Abstract

<P>PROBLEM TO BE SOLVED: To realize saving energy and suppression of exhaust gas by alleviating wind force load received when driving by the wall of a container protruding from the roof above driver's seat of a truck in front view. <P>SOLUTION: A rotating body rotating by the wind force with a blade 2 and a belt is installed on a front wall of a container 8, and the direction of air flow generated when driving the truck is changed by the blade so as not hit the wall to the utmost, and drag force is reduced by making the blade move as required in the direction of air flow by the force of the wind. <P>COPYRIGHT: (C)2004,JPO

Description

2. Description of the Related Art Electric vehicles [Prior art] Conventional electric vehicles have a low energy density of secondary batteries mounted thereon, forcing a large number of batteries to be loaded. It was short and the charging time while stopped was extremely long, which was a major barrier to the spread of electric vehicles.
[Means to solve the problem]
An electrolyte storage tank is installed outside the lead battery, and is connected to the electrolyte tank via a sliding shutter to replenish the electrolyte during discharge. In addition, a discharge tank is provided outside the mixed liquid generated by the discharge in the battery container with another sliding shutter interposed therebetween, and the mixed liquid is discharged so that the electrolytic liquid is always kept in a dischargeable state. On the other hand, since the electrode also decreases with the discharge, a part of the electrode is taken out of the electrolytic solution tank and filled with a paste-like or clad-like electrode to perform a continuous discharge. As one specific example, the electrode plate is replaced with a disk shape and assembled in a coil shape, the lower half is immersed in the electrolyte solution, and the upper half is pressed into the electrode as a place to replenish the reduced electrode. When the lower half electrode is reduced by the discharge, the electrode of the disk is rotated 180 degrees to reverse the upper and lower sides so that the discharge is always continued when necessary.
[Action]
The battery keeps the electrolyte in a dischargeable state by replenishing the battery with consumables from the outside of the battery during discharge, and continuously discharges the battery to reduce the need for charging in the battery case. By removing the battery, the continuous running of the electric vehicle equipped with the battery was greatly extended.

DETAILED DESCRIPTION OF THE INVENTION
To reduce the wind load hitting the front wall of the container, which is higher than the truck roof, a slope plate is installed in front of the container, and the surrounding area is pressed against the wind while contacting the surface of the slope plate. The airflow of the wind blowing from the front with the blades and belt rotating while moving is directed by the blades and passes without hitting the container wall, reducing drag, saving energy and consequently suppressing exhaust gas emission. system.
[Comparison with the conventional method] In the case of a sinus plate with only a fixed inclined plate used for the same purpose as the conventional one, the antibody receives the wind once and the airflow flows along the slope on it. The drag is inevitably increased, and especially when the speed of the truck is low, the flow of the air current is not large, and the amount of air deflecting to the side along the flow is small, so the drag attenuation rate is not so high. Therefore, there is a defect that the energy saving effect is not good when traveling in an urban area other than at a high speed because the gravity increases excessively. In contrast, the present invention moves the blade, which is the fulcrum of the pressure at which the wind pressure generates a drag, constantly along the direction in which the wind travels, and directs the wind direction above the container wall by the blade, so that the wind pressure is weak. However, since the wind path deflects the antibody and generates little drag, energy saving effects can be obtained even when the truck is running in urban areas.

To continuously use lead-acid batteries used as power sources for automobiles, and to continuously supply external consumable substances from the materials circulated in the battery case, and to charge them in the battery case. A battery with a structure that eliminates the need to regenerate depleted materials and enables continuous discharge. In the case of a lead-acid battery, the depleted materials in the battery case include electrolyte and lead and lead oxide as electrodes, The electrolyte solution is applied to the paste made of dilute sulfuric acid or the clad made of the lead oxide active material, and the electrolyte solution is replenished into the battery case with a storage tank for the electrolyte solution installed outside the lead battery with a slide shutter interposed. By installing a discharge port at the bottom of the battery case and connecting it to the waste liquid storage tank provided outside the lead battery with another slide shutter, it is possible to circulate the electrolyte without charging.
