Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a storage battery storage box that stores a storage battery inside and is mainly installed under the floor of a wheel.

[0002]

[Prior art]

 A conventional storage battery storage box comprises a rectangular housing A, in which a desired number of sealed storage batteries B are stored, and which is mainly used for mounting storage batteries B, B under the floor of a wheel. . In the drawing, C is a trolley on which the storage battery group B is mounted, D is a wheel mounting plate disposed on the left and right of the top surface of the top of the housing A, and E is a hinge F at the front opening of the housing A. A cover plate G that can be rotated and opened / closed via a fixing device G is a fixing device including a bolt for fixing the cover plate E in a closed state and a wing nut screwed to the bolt.

As described above, since the storage battery B stored in the storage box generates heat during overcharging and discharging, the heat needs to be discharged to the outside. The side wall plate H is provided with a transparent window I, and the outer surface of the transparent window I is covered with a so-called armor-punched plate L having a large number of downward air passages K provided with eaves J so as to be attached with heat. Release is permitted, but water is prevented from entering from the outside. Further, a wire mesh M is stretched over the transparent window I to prevent dust from entering from the outside.

[0004]

[Problems to be solved by the device]

 As in the conventional case, the storage battery storage box having the above-mentioned configuration must allow the heat radiation and have a waterproof structure. Therefore, the eaves J of each ventilation port K are above the ventilation port K in detail. The structure is such that the surface is covered from the front side to both side walls, and the ventilation port K is opened only downward. However, when actually tested, as shown in FIG. 7, as shown in FIG. External water wraps around from the lower edges on both sides as shown by the arrow, and further, the invading water enters the inside of the housing A from the mesh of the wire mesh M stretched over the transparent window I, It was found that its waterproofness was defective. Therefore, it is desirable to improve waterproofness.

[0005]

[Means for Solving the Problems]

 The present invention solves the above-mentioned conventional problems and provides a storage box for a storage battery that satisfies the above-mentioned demands. The configuration of the storage box is such that a net is attached to a transparent window provided on a side wall of a housing for storing the storage battery. In addition, the peripheral wall of the transparent window is provided with a space on the outer surface of the transparent window, and a frame wall is provided so as to close both side surfaces along with the upper surface of the space, and the front surface of the space is provided. Is covered with a covering wall provided with a large number of vent holes.

[0006]

[Action]

 A net stretched through the window provided on the side wall of the housing prevents dust from entering from the outside. Even if external water enters through the multiple vents of the covering wall, the space existing between the covering wall and the transparent window prevents the invading water from reaching the transparent window. Water is prevented from entering the housing. Further, since the space has its upper surface as well as its both side surfaces closed by the frame wall, water from the outside is prevented from entering the space by the frame wall. On the other hand, the heat generated from the storage battery is not only released to the outside through the through-holes through the large number of vent holes of the coating wall in front of it, but also outside through the opening on the lower surface of the space, The heat radiation cooling effect in the housing is large.

【Example】

 An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a rear view of a storage battery storage box according to an embodiment of the present invention, which is composed of a rectangular parallelepiped casing 1 and is not shown, but a plurality of sealed storage batteries are mounted on a trolley as in the conventional case. The front opening is closed by a cover plate that can be closed and fixed in a closed state with bolts and screw nuts.Wheels are installed on the left and right of the top surface of the top plate wall. It has a configuration in which it is mounted under the floor of the wheel with plates 2 and 2.

The storage battery storage box of the present invention is characterized in that the side wall of the housing 1, that is, the side wall 3 constituting the back surface of the housing 1 in the illustrated example, is waterproof and breathable. The following structure should be provided.

That is, a transparent window 4 is provided on the side wall 3 of the housing 1, and a net 5 such as a wire net for preventing dust from entering the transparent window 4 is stretched. The peripheral portion of the net 5 is fixed to the back surface of the peripheral wall portion of the transparent window 4 by an appropriate fixing means such as an adhesive, a nail or a tack. This structure is the same as the conventional one, but according to the present invention, it has the following characteristic structure. That is, the peripheral wall of the transparent window 4 is provided with a space 6 on the outer surface of the transparent window 4, and a frame wall 9 is provided so as to close both side surfaces in parallel with the upper surface of the space 6, and the front surface of the space 6 is provided. Is covered with a covering wall 8 having a large number of vent holes 7.

Preferably, the above-mentioned characteristic structure can be formed by attaching one of the following bulging plates 10 manufactured separately from the housing 1 to the peripheral wall portion of the through window 4 of the housing 1. This brings the advantage of facilitating the manufacture of the storage box of the present invention.

That is, as shown in FIG. 1, the bulging plate 10 is formed by bending a single plate material and covering the cover wall 8 having a large number of vent holes 7 and the upper edge and both sides of the cover wall 8. The U-shaped frame wall 9 is formed by bending the edge at a right angle, and the U-shaped mounting plate portion 11 is formed by bending the tip of the U-shaped frame wall 9 outward at a right angle.

In this case, the plurality of ventilation holes 7 of the covering wall 8 are regularly arranged and each of them has the eaves 12 projecting from the upper surface to the front surface and both side surfaces in the same manner as in the conventional case, and the downward ventilation is performed. It is preferably formed on the mouth 7, and is formed on a so-called stirrup punched plate.

The U-shaped mounting plate portion 11 of the bulging plate 10 manufactured in this manner is applied to the outer surface of the peripheral wall portion of the transparent window 4 of the rear side wall 3 and is arranged at regular intervals on the mounting plate portion 11. The storage battery storage housing of the present invention is easily and inexpensively manufactured by attaching the storage housing to the wall surface with the screw 13 through the provided mounting hole.

Thus, the space between the transparent window 4 of the space 6 and the covering wall 8 can be obtained in accordance with the degree of protrusion of the U-shaped frame wall 9 of the bulging plate 10, so that the frame can be obtained. If the projection of the wall 9 is appropriately set in advance, the desired size of the space 6 can be obtained. According to many experiments, the size of the space 6 larger than the water droplet is sufficient if it is at least larger than the diameter of the water droplet, but it is generally preferable that the size is 15 mm or more.

Further, the U-shaped frame wall 9 of the swelling plate 10 prevents water from entering the space 4 from above and both sides thereof, while the space 6 surrounded by the U-shaped frame wall 9 is below the water. An opening 14 communicating with the outside air is formed on the surface so that the hot air emitted from the transparent window 4 can be emitted to the outside through the opening 14. In the drawing, reference numeral 15 denotes a reinforcing bar provided in the center of the transparent window 4, and 16 projects inward from an intermediate portion of the covering wall 10 and abuts on the bar 15 and the peripheral wall portion of the transparent window 4 to support the covering wall 10. A reinforcing tubular body, 17 is a fixing screw that is inserted into the tubular body 16 and is screwed to the crosspiece 15 and the peripheral wall portion of the transparent window 4, and 18 is an annular packing.

In the storage box of the present invention, a plurality of sealed storage batteries are stored according to a conventional method, and the storage batteries are used under the floor of the wheel for use. The air is not only discharged from the window 4 through a large number of downward vents 7, 7, ... Of the covering wall 8 in front of the window 4, but is also discharged through the large open surface 14 below the space 6. Since the heat is dissipated in the air, its heat dissipation and cooling effect is significantly increased.

On the other hand, even if external water enters through the many downward ventilation holes 7, 7, ... Of the covering wall 8, the space 6 exists, so that the invading water is absorbed by the space 6 by the transparent window. It is separated from 4, and the invasion from the transparent window 4 is surely prevented, whereby the waterproof property in the housing 1 is secured. The U-shaped frame wall 9 prevents water and dust from above and both sides thereof from entering the space 6. The net 5 stretched over the transparent window 4 prevents external dust from entering the housing 1 as in the conventional case.

[0018]

[Effect of device]

 As described above, the storage battery storage box of the present invention not only prevents external dust from entering the housing by stretching the net through the transparent window provided on the side wall of the housing storing the storage battery. Instead, the peripheral wall of the transparent window is provided with a frame wall that occupies a space on the outer surface of the transparent window and closes both side surfaces along with the upper surface of the space. Since the ventilation holes of the cover are covered by the provided covering wall, the frame wall prevents water from entering the space, and even if water enters from the many vents of the covering wall, By the space, it is possible to prevent the water from reaching the transparent window, and thus to surely prevent the water from entering the housing, while the hot air of the storage battery discharged from the transparent window is In addition to being able to dissipate to the outside from the multiple ventilation holes of the cover plate, Because it is dissipated to the outside through the opening, compared to the conventional storage box facilitating release of hot air, and quickly, with the effect of such a cooling effect of the housing of the battery may significantly increase.
