Description

Technical Field

[0001] The utility model relates to the technical field of gas detection alarms, and particularly relates to an explosion-proof battery box for a gas detection alarm. Background Art

[0002] Gas detection alarms need to be powered to operate, so a battery box is required to supply power to ensure the normal operation of the gas detection alarm.

[0003] During the overload operation of the existing explosion-proof battery box, an explosion may occur. The main reason for the explosion is that the battery generates heat, causing a large amount of heat to accumulate inside the battery box, resulting in a poor heat dissipation effect of the battery box, a rapid increase in the internal temperature of the battery box, and finally an explosion of the battery due to the increased temperature, posing a danger. Content of the Utility Model

[0004] The purpose of the utility model is to provide an explosion-proof battery box for a gas detection alarm to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a battery box body assembly and a polyurethane fiber rope. The battery box body assembly includes a battery box cover, a hinge, an elastic strap, and an explosion-proof battery box body. One side of the battery box cover is connected with a hinge, the lower end of the battery box cover is connected with the explosion-proof battery box body, and an elastic strap is installed at the upper end of the battery box cover. The polyurethane fiber rope is located on one side of the battery box body assembly.

[0006] Preferably, a helium sensor is installed above the battery box body assembly, and a protective partition pad is arranged inside the battery box body assembly.

[0007] Preferably, a battery assembly is arranged inside the protective partition pad, and an electrode connection assembly is arranged above the battery assembly.

[0008] Preferably, the battery assembly includes a battery body, a battery fixing frame, a battery connection electrode, and an electrode fixing wire. The battery fixing frame is arranged outside the battery body, the battery connection electrode is connected to the upper end of the battery body, and the electrode fixing wire is arranged above the battery connection electrode.

[0009] Preferably, the electrode connection assembly includes an electrode connection column, an electrode installation column, and an electrode telescopic column. The lower end of the electrode connection column is connected with the electrode installation column, and the lower end of the electrode installation column is connected with the electrode telescopic column.

[0010] Preferably, the electrode connection assembly further includes a spring and a battery contact post, a spring is disposed outside the electrode telescopic post, and the lower end of the spring is connected to the battery contact post.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When excessive heat accumulates inside the explosion-proof battery box of this device, it will cause the surface temperature of the explosion-proof battery box to be too high, which will cause the polyurethane fiber rope of the explosion-proof battery box to melt, resulting in the battery box cover losing its traction effect. At this time, relying on the elasticity of the elastic strap, the battery box cover that forms a rotating structure with the explosion-proof battery box through the hinge can be opened, so that the inside and outside of the device are connected, facilitating the device to dissipate heat quickly, reducing the internal temperature of the device, and preventing the battery from exploding.

[0013] 2. The inside of the explosion-proof battery box of this device is filled with helium. By means of helium, the battery body can be isolated, achieving a flame-retardant effect. At the same time, the protective partition pad can isolate the battery body from the explosion-proof battery box. When the device is hit and broken by a sharp object, due to the isolation space provided by the protective partition pad, the sharp object cannot immediately damage the battery body when it penetrates the device. At the same time, when the explosion-proof battery box is broken, helium will leak, and at this time, the helium sensor will detect the change in the helium concentration and alarm to remind the staff that this device is damaged.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 and Figure 2 The present invention provides a technical solution: including a battery box body assembly 1 and a polyurethane fiber rope 2. The battery box body assembly 1 includes a battery box cover 101, a hinge 102, an elastic strap 103 and an explosion-proof battery box body 104. One side of the battery box cover 101 is connected to the hinge 102, the lower end of the battery box cover 101 is connected to the explosion-proof battery box body 104, and an elastic strap 103 is installed at the upper end of the battery box cover 101. The polyurethane fiber rope 2 is located on one side of the battery box body assembly 1;

[0021] When too much heat accumulates inside the explosion-proof battery box body 104, it will cause the surface temperature of the explosion-proof battery box body 104 to be too high, which will cause the explosion-proof battery box body 104 to fuse the polyurethane fiber rope 2, so that the battery box cover 101 loses the traction effect. At this time, relying on the elasticity of the elastic strap 103, the battery box cover 101 that forms a rotating structure with the explosion-proof battery box body 104 through the hinge 102 can be opened, so that the inside and outside of the device are connected, facilitating the device to dissipate heat quickly, so that the internal temperature of the device is reduced, and thus preventing the battery from exploding.

[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a helium sensor 3 is installed above the battery box body assembly 1, and a protective partition pad 4 is arranged inside the battery box body assembly 1. A battery assembly 5 is arranged inside the protective partition pad 4, and an electrode connection assembly 6 is arranged above the battery assembly 5;

[0023] The inside of the explosion-proof battery box body 104 is filled with helium. By means of helium, the battery body 501 can be isolated, achieving a flame-retardant effect. At the same time, the protective partition pad 4 can isolate the battery body 501 from the explosion-proof battery box body 104. When the device is hit and broken by a sharp object, due to the isolation space provided by the protective partition pad 4, when the sharp object inserts into the device, it cannot immediately damage the battery body 501. At the same time, when the explosion-proof battery box body 104 is broken, helium will leak. At this time, the helium sensor 3 will detect the change in the helium concentration and thus alarm to remind the staff that this device is damaged.

[0024] As Figure 3As shown, the battery assembly 5 includes a battery body 501, a battery fixing bracket 502, a battery connection electrode 503, and an electrode fixing wire 504. The battery fixing bracket 502 is disposed outside the battery body 501. The upper end of the battery body 501 is connected to the battery connection electrode 503, and the electrode fixing wire 504 is disposed above the battery connection electrode 503.

[0025] Place the battery body 501 in the battery fixing bracket 502, then connect the electrodes of multiple battery bodies 501 together through the battery connection electrode 503, and fix the battery connection electrode 503 with the electrode fixing wire 504.

[0026] As Figure 4 shown, the electrode connection assembly 6 includes an electrode connection post 601, an electrode mounting post 602, and an electrode telescopic post 603. The lower end of the electrode connection post 601 is connected to the electrode mounting post 602, the lower end of the electrode mounting post 602 is connected to the electrode telescopic post 603. The electrode connection assembly 6 further includes a spring 604 and a battery contact post 605. The spring 604 is disposed outside the electrode telescopic post 603, and the lower end of the spring 604 is connected to the battery contact post 605.

[0027] The elastic telescopic structure formed by the battery contact post 605, the spring 604, and the electrode telescopic post 603 with the battery box cover 101 facilitates the contact between the battery contact post 605 and the battery connection electrode 503, so that the electricity inside the battery body 501 can be supplied to the electrode mounting post 602, making the electrode mounting post 602 charged.

[0028] Working principle: First, place the battery body 501 in the battery fixing bracket 502, then connect the electrodes of multiple battery bodies 501 together through the battery connection electrode 503, and fix the battery connection electrode 503 with the electrode fixing wire 504. After the battery assembly 5 is assembled, fill a certain amount of protective partition pads 4 inside the explosion-proof battery box 104, and then place the battery assembly 5 in the explosion-proof battery box 104. Protect the battery assembly 5 by the protective partition pads 4. Then, rely on the rotating structure formed by the battery box cover 101 and the explosion-proof battery box 104 through the hinge 102 to close the battery box cover 101. While the battery box cover 101 is being closed, fill helium gas inside the explosion-proof battery box 104 through the flexible pipeline to reduce the air content inside the explosion-proof battery box 104, and carry out a certain degree of flame retardancy with helium gas. After the battery box cover 101 is completely closed, fix one end of the polyurethane fiber rope 2 with bolts, so that the polyurethane fiber rope 2 pulls the battery box cover 101 to keep the battery box cover 101 in a closed state. At this time, the battery contact post 605 forms an elastic telescopic structure with the battery box cover 101 through the spring 604 and the electrode telescopic post 603, which is convenient for the battery contact post 605 to contact the battery connection electrode 503, so that the electricity inside the battery body 501 can be supplied to the electrode mounting post 602, making the electrode mounting post 602 charged. When the device is in use, just connect the power cord of the gas detection alarm to the two electrode mounting posts 602 and fix it through the electrode connection post 601. When the temperature of the device is too high, the polyurethane fiber rope 2 will be melted, so that the battery box cover 101 opens for heat dissipation. When the explosion-proof battery box 104 is damaged, the helium gas sensor 3 will detect a decrease in the helium gas content inside the explosion-proof battery box 104 and give an alarm to remind the staff.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
