[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figs. 1 to 4 The utility model provides a technical scheme.

[0023] The energy storage cabinet body sealing detection tool comprises a base 1, a sealing cover 3 is clamped on the top of the base 1, a sealing cavity is formed in the clamped part of the base 1 and the sealing cover 3, the sealing cover 3 is provided with an air outlet, a pressure gauge 6 for detecting the pressure in the sealing cavity is installed on the sealing cover 3, and a sealing strip is extruded and attached to the joint gap between the base 1 and the sealing cover 3. The energy storage cabinet body is placed on the base 1, then the sealing cover 3 is clamped on the top of the base 1, the energy storage cabinet body is placed in the sealing cavity formed by the clamped part of the base 1 and the sealing cover 3, then the air outlet is connected to a vacuum pump, the vacuum pump is started to extract the air in the base 1, then the pressure in the sealing cavity is detected by the pressure gauge 6, if the pressure changes greatly, it is judged that the sealing property of the energy storage cabinet body is poor, which is based on the gas pressure balance and leakage principle. When the vacuum pump is started to extract the air in the base 1, the gas in the sealing cavity is continuously extracted, the number of gas molecules decreases, according to the ideal gas state equation pV = nRT, under the condition that the volume and temperature are relatively stable, the decrease of the amount of substance of the gas will cause the pressure in the sealing cavity to decrease, thereby forming a relatively low-pressure environment.

[0024] If the energy storage cabinet body is well sealed, there is no additional gas entering or escaping in the sealed cavity except for a small amount of gas that may remain due to incomplete vacuum pumping. At this time, the pressure in the sealed cavity detected by the pressure gauge 6 should be relatively stable and will not change significantly. However, if the energy storage cabinet body is not well sealed, there are gaps or holes, and external air will enter the sealed cavity through these leakage points under the action of pressure difference. With the entry of external air, the number of gas molecules in the sealed cavity increases. According to the ideal gas state equation, the amount of gas substance increases under the condition of constant volume and temperature, and the pressure rises. Therefore, when the pressure change in the sealed cavity is detected by the pressure gauge 6, it can be determined that there is a sealing problem in the energy storage cabinet body, and air enters the sealed cavity through the leakage points in the cabinet body.

[0025] The base 1 and the sealing cover 3 are square, and the top of the base 1 is fixedly connected with a square ring 2, which is used for positioning the sealing cover 3. When the sealing cover 3 is connected with the base 1, the outer surface of the square ring 2 is respectively tightly attached to the inner wall of the sealing cover 3 on four sides, thereby limiting the sealing cover 3. Further, those skilled in the art can apply the technology well known in the art to apply pressure to the sealing cover 3 from the top end of the sealing cover 3, for example, by adding a weight on the top of the sealing cover 3 or mechanically pressing the top of the sealing cover 3.

[0026] The sealing strip includes two long sealing pads 10 and two short sealing pads 12. The two long sealing pads 10 are used to seal the gaps between the front and rear connections of the base 1 and the sealing cover 3, and the two short sealing pads 12 are used to seal the gaps between the left and right connections of the base 1 and the sealing cover 3. By extruding the long sealing pads 10 and the short sealing pads 12 at the gaps between the base 1 and the sealing cover 3, the sealing property of the gaps is increased.

[0027] It also includes four mounting plates 7, which are respectively arranged around the base 1. The surface of each mounting plate 7 is mounted with an electric hydraulic push rod 8. The four electric hydraulic push rods 8 are respectively used to drive the two long sealing pads 10 and the two short sealing pads 12 to extrude at the gaps between the base 1 and the sealing cover 3. By setting the electric hydraulic push rod 8, the sealing cover 3 drives the sealing strip away when it is disassembled, and drives the sealing strip to be tightly attached after the sealing cover 3 is connected.

[0028] Conventionally, the mounting plate 7 is fixed in the tool as a whole, which can be fixed to the ground or the wall. Similarly, the base 1 is also fixed, and the pressure gauge 6 and the electric hydraulic push rod 8 can be selected and purchased according to the needs in the existing products by those skilled in the art.

[0029] The opposite ends of the two electric hydraulic push rods 8 are fixedly connected with short push plates 11, the opposite surfaces of the two short push plates 11 are respectively connected with two short sealing pads 12, the short push plates 11 are driven to move by the electric hydraulic push rods 8, so as to drive the short sealing pads 12 to move, the opposite ends of the two electric hydraulic push rods 8 are fixedly connected with long push plates 9, the opposite surfaces of the two long push plates 9 are respectively connected with two long sealing pads 10, the long push plates 9 are driven to move by the electric hydraulic push rods 8, so as to drive the long sealing pads 10 to move, and further, the skilled in the art can apply the technology known in the art to the long push plates 9 and the short push plates 11 to exert a pushing force, for example, the surface of each mounting plate 7 is provided with a plurality of electric hydraulic push rods 8 arranged at equal intervals, and the surface of each long push plate 9 and short push plate 11 is subjected to a uniform pushing force.

[0030] Further, the side edges of the front and rear long sealing pads 10 are connected with the side edges of the corresponding left and right short sealing pads 12, and together form a rectangular frame structure.

[0031] The sealing cover 3 is fixedly provided with a communication pipe 4 at the air outlet, the end of the communication pipe 4 is coaxially fixedly connected with a flange 5, and the flange 5 is connected with the flange of the vacuum pump, and the skilled in the art knows that a rubber gasket is arranged between the two flanges to increase the sealing performance during connection.

[0032] The specific scheme is that the flange 5 is connected with the flange of the vacuum pump through a rubber gasket, so as to ensure firm connection and good sealing, thereby preventing air leakage during air extraction.

[0033] Placing the energy storage cabinet body: the energy storage cabinet body is stably placed on the base 1, the sealing cover 3 is positioned by the square ring 2, the sealing cover 3 is clamped on the top of the base 1, the four electric hydraulic push rods 8 are started to drive the two long sealing pads 10 and the two short sealing pads 12 to move, the left and right electric hydraulic push rods 8 drive the short sealing pads 12 to move through the short push plates 11 fixedly connected at the opposite ends, the front and rear electric hydraulic push rods 8 drive the long sealing pads 10 to move through the long push plates 9 fixedly connected at the opposite ends, the long sealing pads 10 and the short sealing pads 12 are extruded at the gap between the base 1 and the sealing cover 3, and the sealing performance is increased, since the side edges of the front and rear long sealing pads 10 are connected with the side edges of the corresponding left and right short sealing pads 12, and together form a rectangular frame structure, the overall sealing can be better achieved.

[0034] Air extraction and pressure detection: the vacuum pump is started, the air in the sealed cavity is extracted through the air outlet of the sealing cover 3, so as to form a relatively low-pressure environment in the sealed cavity, and during the air extraction process and after the air extraction is completed, the pressure change in the sealed cavity is detected in real time by the pressure gauge 6, and the pressure data is recorded after a period of observation, for example, 10-30 minutes.

[0035] Judge the sealing: if in the observation time, the pressure in the sealed cavity is relatively stable, there is no large amplitude change, it shows that the energy storage cabinet body sealing is good, if the pressure change in the sealed cavity is big, the pressure is obviously increased, it is judged that the energy storage cabinet body has sealing problem, there is air through the cabinet leakage point into the sealed cavity;

[0036] After the detection is finished, the vacuum pump is closed, the electric hydraulic push rod 8 drives the sealing strip long sealing gasket 10 and the short sealing gasket 12 to be far away from the connecting gap of the base 1 and the sealing cover 3 first, then the sealing cover 3 is detached from the base 1, and then the energy storage cabinet body is taken out.
