Description

Technical Field

[0001] This utility model belongs to the field of energy storage cabinets, specifically relating to a climate protection device for a rupture plate used in energy storage cabinets. Background Technology

[0002] Energy storage cabinets are devices used to store electrical energy, and their safety is of paramount importance. To ensure safety, some energy storage cabinets may be equipped with safety devices such as rupture plates, which are used to release pressure when the internal pressure is too high, preventing explosions and damage.

[0003] Under the influence of different climates, the batteries and other components inside the energy storage cabinet may experience additional pressure due to thermal expansion. If the internal pressure is too high, it may cause safety problems such as the outer shell of the energy storage cabinet cracking or the pressure relief valve opening. This could lead to uncontrolled chemical reactions in the batteries inside the energy storage cabinet, resulting in fires and other problems.

[0004] Therefore, a climate protection device for rupture plates in energy storage cabinets is proposed. It has a climate protection structure and monitors the internal air pressure of the energy storage cabinet according to climate change, so as to perform pressure relief in a timely manner. This solves the problem that the energy storage cabinet may explode and damage internal components due to uneven air pressure inside and outside the energy storage cabinet caused by climate change during daily use. Utility Model Content

[0005] To overcome the risk of explosion and damage to internal components caused by uneven air pressure inside and outside the energy storage cabinet due to climate change, a climate protection device with a rupture plate for the energy storage cabinet is proposed.

[0006] The technical solution of this utility model is as follows: a climate protection device for a rupture plate of an energy storage cabinet, including a first fixed frame, a spring, and a buffer assembly. A mounting frame is fixedly connected to the rear end of the first fixed frame, and a first frame is fixedly connected to the rear end of the inner wall of the mounting frame. A sleeve is provided through the center of both ends of the first frame, and a vent valve is provided through the rear end of the sleeve. A mounting groove is opened at the front end of the first fixed frame, and a pressure sensor is provided on the mounting groove. A protective shell is fixedly connected to the inner wall of the first fixed frame, and a reset assembly is provided on the protective shell. The reset assembly includes a second fixed frame. A second fixed frame is fixedly connected to the rear end of the inner wall of the protective shell, and a buffer assembly is provided on the second fixed frame.

[0007] Preferably, an explosion-proof plate is fixed to the inner wall of the mounting frame, and a first groove is provided at the center of the front and rear ends of the explosion-proof plate, with the inner wall of the first groove fitting against the outer wall of the sleeve.

[0008] Preferably, the protective shell has evenly distributed vent holes through both the front and rear ends, and a third groove is through the center of both the front and rear ends of the protective shell, with the inner wall of the third groove fitting against the outer wall of the sleeve.

[0009] Preferably, the reset assembly also includes a fourth groove, a spring, and a sliding column; the fourth groove is provided at the four corners of the front end of the second fixing frame, the spring is fixedly connected to the rear end of the inner wall of the fourth groove, the other end of the spring is fixedly connected to the sliding column, and the outer wall of the sliding column is in contact with the inner wall of the fourth groove.

[0010] Preferably, the buffer assembly includes an explosion-proof pressure plate, a second frame, a fixed column, a first rubber column, a second rubber column, and a third rubber column; the front ends of the four sliding columns are jointly placed with an explosion-proof pressure plate, and a second groove is opened at the four corners of the front end of the protective shell. A threaded groove is opened at the rear end of the inner wall of the second groove, and a baffle is placed on the second groove. A stud is provided on the baffle, and the stud passes through the baffle and is threaded into the threaded groove. The rear end of the baffle is in contact with the front end of the explosion-proof pressure plate.

[0011] Preferably, the explosion-proof pressure plate is fixedly connected to a second frame at its rear end, and the rear end of the second frame is fixedly connected to evenly distributed fixing columns. The rear end of the fixing columns is fixedly connected to a first rubber column, and the rear end of the first rubber column is fixedly connected to a second rubber column.

[0012] Preferably, the first rubber column corresponds one-to-one with the vent hole, the outer wall of the first rubber column is fitted with the inner wall of the vent hole, and the front end of the second rubber column is fitted with the rear end of the protective shell.

[0013] Preferably, a third rubber column is fixedly connected to the rear end of the explosion-proof pressure plate, the outer wall of the third rubber column is in contact with the inner wall of the sleeve, and the four sides of the outer wall of the explosion-proof pressure plate are in contact with the four sides of the inner wall of the protective shell.

[0014] As a preferred option, the explosion-proof pressure plate has a number of tiny micro-holes running through its front and rear ends.

[0015] The beneficial effects of this utility model are:

When the weather protection device reaches an unexpected predetermined threshold, the explosion-proof plate will break on its own to release the overall pressure, thereby protecting the integrity of the subsequent devices. The weather protection device can be put into operation again after the explosion-proof plate is reinstalled on the mounting frame.

[0018] 3. However, when the front end of the explosion-proof pressure plate is attached to the rear end of the baffle, the outer wall of the first rubber column is attached to the inner wall of the vent hole, thereby isolating the air at the front end of the protective shell from the air at the rear end of the protective shell. Through the tiny micropores on the explosion-proof pressure plate, the gas can slowly flow into the space between the explosion-proof pressure plate and the protective shell, thereby carrying out subsequent depressurization work.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-6 This utility model provides an embodiment of a weather protection device for a rupture plate in an energy storage cabinet, comprising a first fixed frame 1, a spring 103, and a buffer assembly. A mounting frame 4 is fixedly connected to the rear end of the first fixed frame 1. A first frame 5 is fixedly connected to the rear end of the inner wall of the mounting frame 4. A sleeve 6 is provided through the center of both ends of the first frame 5. A vent valve 9 is provided through the rear end of the sleeve 6. A mounting groove 2 is provided at the front end of the first fixed frame 1, and a pressure sensor 3 is provided on the mounting groove 2.

The second fixing frame 101 is fixedly connected to the rear end of the inner wall of the protective shell 10, and a buffer assembly is provided on the second fixing frame 101. By installing the climate protection device on the closed door of the energy storage cabinet, a chamber is formed by the mounting frame 4 and the protective shell 10 to alleviate the air pressure difference caused by climate in the energy storage cabinet. The pressure relief work of the device is carried out by the sleeve 6 and the vent valve 9 in combination with the buffer assembly and the reset assembly, thereby improving the overall service life of the energy storage cabinet and improving the protection of the energy storage cabinet.

[0029] Please see Figures 2-3 In this embodiment, an explosion-proof plate 7 is fixedly connected to the inner wall of the mounting frame 4. A first groove 8 is provided at the center of the front and rear ends of the explosion-proof plate 7. The inner wall of the first groove 8 is in contact with the outer wall of the sleeve 6. When the climate protection device reaches an unexpected predetermined threshold, the explosion-proof plate 7 performs overall pressure relief by breaking itself, thereby protecting the integrity of the subsequent device. The climate protection device can be put into operation again after the explosion-proof plate 7 is reinstalled on the mounting frame 4.

[0030] Please see Figures 3-4 In this embodiment, the reset assembly further includes a fourth groove 102, a spring 103, and a sliding column 104. The fourth groove 102 is provided at the four corners of the front end of the second fixing frame 101. The spring 103 is fixedly connected to the rear end of the inner wall of the fourth groove 102. The other end of the spring 103 is fixedly connected to the sliding column 104. The outer wall of the sliding column 104 is in contact with the inner wall of the fourth groove 102. By pushing the sliding column 104 through the reaction force generated by the spring 103, the explosion-proof pressure plate 201 after depressurization can be reset.

[0031] Please see Figures 5-7In this embodiment, the protective shell 10 has evenly distributed vent holes 15 extending through its front and rear ends, and a third groove 16 extending through its center at both ends. The inner wall of the third groove 16 fits against the outer wall of the sleeve 6. The buffer assembly includes an explosion-proof pressure plate 201, a second frame 202, a fixing post 203, a first rubber post 204, a second rubber post 205, and a third rubber post 206. The front ends of the four sliding posts 104 are all equipped with an explosion-proof pressure plate 201, and the four corners of the front end of the protective shell 10 are provided with... The device includes a second groove 11, with a threaded groove 12 at the rear end of its inner wall. A baffle 13 is placed on the second groove 11, and a stud 14 is installed on the baffle 13. The stud 14 passes through the baffle 13 and is threaded onto the threaded groove 12. The rear end of the baffle 13 is fitted against the front end of the explosion-proof pressure plate 201. A second frame 202 is fixedly connected to the rear end of the explosion-proof pressure plate 201. Evenly distributed fixing posts 203 are fixedly connected to the rear end of the second frame 202. A first rubber post 204 is fixedly connected to the rear end of each fixing post 203. A second rubber post 205 is fixedly connected to the rear end. The first rubber post 204 corresponds one-to-one with the vent hole 15. The outer wall of the first rubber post 204 is in contact with the inner wall of the vent hole 15. The front end of the second rubber post 205 is in contact with the rear end of the protective shell 10. A third rubber post 206 is fixedly connected to the rear end of the explosion-proof pressure plate 201. The outer wall of the third rubber post 206 is in contact with the inner wall of the sleeve 6. The four sides of the outer wall of the explosion-proof pressure plate 201 are in contact with the four sides of the inner wall of the protective shell 10. When the front end of the explosion-proof pressure plate 201 is in contact with the rear end of the baffle 13... The outer wall of the first rubber column 204 is in contact with the inner wall of the vent hole 15, thereby isolating the air at the front end of the protective shell 10 from the air at the rear end of the protective shell 10. When the sleeve 6 is in a closed space, the third rubber column 206 fixes the position of the explosion-proof pressure plate 201. The front and rear ends of the explosion-proof pressure plate 201 are provided with a number of small micro-holes. Through the small micro-holes on the explosion-proof pressure plate 201, the gas can slowly flow into the space between the explosion-proof pressure plate 201 and the protective shell 10, thereby carrying out subsequent depressurization work.

[0032] By installing the device on the closed door of the energy storage cabinet, after installation, the explosion-proof pressure plate 201 is pressed against the baffle plate 13 by the reaction force of the fourth groove 102 on the sliding column 104. By closing the vent valve 9, the space formed by the rear end of the sleeve 6 and the third rubber column 206 is filled with gas, so the explosion-proof pressure plate 201 cannot move backward due to the influence of the third rubber column 206. The pressure sensor 3 on the mounting groove 2 senses when the internal pressure of the energy storage cabinet is too high. By opening the vent valve 9, the sleeve 6 forms a through space, and the explosion-proof pressure plate 201 is pushed by the internal pressure of the energy storage cabinet. The first rubber column 204 is pushed backward on the vent hole 15, while the third rubber column 206 slides backward in the sleeve 6, so that the fixed column 203 is located in the vent hole 15. Then, the air in the energy storage cabinet is depressurized with the outside air through the vent hole 15. After the depressurization is completed, the explosion-proof pressure plate 201 is resisted by the reaction force generated by the spring 103 through the sliding column 104. Then, the vent valve 9 is closed. The overall strength of the rupture plate can be improved by the first frame 5, the protective shell 10, and the second frame 202, thereby improving the durability of the weather protection device of the rupture plate.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
