Description

Technical Field

[0001] The invention relates to the technical field of power distribution equipment, and in particular to an environmentally friendly gas-filled cabinet. Background Art

[0002] The insulated cabinet is also called an insulated electrical cabinet. It achieves insulation by injecting inert gas into the interior so that the inert gas wraps and covers the electronic components in the charging cabinet, thereby improving the safety of the electronic components during the process. When the electronic components in the current inflatable cabinet are abnormal, the pressure in the inflatable cabinet will continue to increase (when the electronic components are abnormal, hot air will be generated in the charging cabinet, so the pressure in the inflatable cabinet will become greater and greater). The existing treatment method is to install a pressure relief valve on the charging cabinet, but the disadvantage of this method is that the pressure relief valve will only open and then discharge the excess gas in the charging cabinet when the pressure in the charging cabinet exceeds the threshold of the pressure relief valve. When the pressure in the inflatable cabinet returns to normal, since the pressure relief valve discharges part of the gas in the inflatable cabinet in advance, the pressure in the charging cabinet cannot reach the pressure before the pressure relief when the inflatable cabinet is used subsequently. When the inflatable cabinet does not reach the pressure required for work, it will be detrimental to the operation of the electronic components in the charging cabinet. Summary of the invention

[0028] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. The selected positional descriptions in the description, such as top, bottom, left, right, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0029] Embodiment 1: An environmentally friendly inflatable cabinet, such as Figure 1-Figure 4As shown, the box body 101 includes a box body 101, a blocking plate 102 is connected to the front side of the box body 101 with bolts, and the blocking plate 102 is provided with a first blocking member 1021 for blocking itself. The box body 101 is provided with a cavity 103. When the cavity 103 is filled with inert gas, it is in a high pressure state. A plurality of electronic components are placed in the cavity 103. The electronic components are used to control or connect external power equipment. The blocking plate 102 is used to block the cavity 103. The upper side of the cavity 103 is fixed with a first blocking member 1021. The first air storage shell 104 has a left side connected to the outside through a connecting pipe that penetrates the box body 101. An elastic diaphragm 105 is fixedly connected to the first air storage shell 104. The basic state of the elastic diaphragm 105 (the state when it is not deformed) is sufficient to adapt to the pressure when the cavity 103 is full of inert gas. When the pressure in the cavity 103 exceeds the pressure required for work, the elastic diaphragm 105 is deformed to the left by the change in pressure and expands the volume in the cavity 103, so that the cavity 103 The pressure inside is kept constant. After the pressure in the cavity 103 reaches the pressure required for work, the elastic diaphragm 105 deforms to the right and resets. A control panel 1 is provided on the left side of the upper part of the box body 101. The box body 101 is provided with a pressure relief component 200 and an air replenishing component 300. The pressure relief component 200 is used to discharge excess gas in the cavity 103. When the pressure in the cavity 103 continues to increase, the excess gas in the cavity 103 is discharged from it and collected by the pressure relief component 200, thereby completing the pressure relief of the cavity 103. The air replenishing component 300 is used to replenish inert gas into the cavity 103. After the pressure in the cavity 103 reaches the pressure required for work, the air replenishing component 300 replenishes inert gas into the cavity 103 to replace the gas leaked from the cavity 103. The box body 101 is provided with a cooling component 500 electrically connected to the control panel 1. The cavity 103 is cooled by the cooling component 500 to keep the pressure and temperature in the cavity 103 at the required working state.

[0030] like Figure 1-Figure 5As shown, the pressure relief assembly 200 includes a first fixing member 201 fixedly connected to the top of the box body 101, the first fixing member 201 is connected to the cavity 103, and a first pressure relief valve 202 is arranged on the lower side of the first fixing member 201. When the pressure in the cavity 103 exceeds the threshold of the first pressure relief valve 202, the first fixing member 201 and the cavity 103 form a passage, and the first pressure relief valve 202 is in an open state. When the pressure in the cavity 103 does not exceed the threshold of the first pressure relief valve 202, the first pressure relief valve 202 is in a closed state to disconnect the connection between the cavity 103 and the first fixing member 201. A first slide plate 203 is sealingly and slidably connected in the first fixing member 201. The first slide plate 203 is The plate 203 is located above the first pressure relief valve 202. When the gas in the cavity 103 enters the first fixing member 201, the first slide plate 203 is driven to move upward. A spring is arranged between the first slide plate 203 and the first fixing member 201. The upper side of the first slide plate 203 is fixedly connected with a first connecting member 204 located in the first fixing member 201. The box body 101 is fixedly connected with a second gas storage shell 205. Inert gas is stored in the second gas storage shell 205. The lower side of the second gas storage shell 205 is connected to the lower side of the first fixing member 201 through an L-shaped tube. A filter 2 for filtering exhaust gas is arranged in the L-shaped tube adjacent to the first fixing member 201. The filter 2 is used to filter the cavity 103. 03 discharges excess gas, the filter element 2 is an activated carbon filter, a second pressure relief valve 206 is arranged in the L-shaped tube adjacent to the first fixing element 201, when the pressure in the first fixing element 201 exceeds the threshold value of the second pressure relief valve 206, the second pressure relief valve 206 is in an open state, at this time the first fixing element 201 forms a passage with the first fixing element 201 through the adjacent L-shaped tube, when the pressure in the first fixing element 201 does not exceed the threshold value of the second pressure relief valve 206, the second pressure relief valve 206 is in a closed state, the first fixing element 201 no longer forms a passage with the first fixing element 201 through the adjacent L-shaped tube, the second pressure relief valve 206 is located between the first slide plate 203 and the first pressure relief valve The first fixing member 201 is provided with a second blocking member 207 which is slidingly connected in a limited position in the first fixing member 201. When the second blocking member 207 moves upward, it blocks the left side of the adjacent L-shaped tube, so that the gas in the cavity 103 will not flow into the adjacent L-shaped tube during the process of leaking into the first fixing member 201. The second blocking member 207 is located between the first slide plate 203 and the first pressure relief valve 202. The threshold value of the second pressure relief valve 206 is smaller than the threshold value of the first pressure relief valve 202. The first fixing member 201 is provided with a deceleration component 400. The deceleration component 400 reduces the speed of the first slide plate 203 moving and resetting, thereby extending the time for the cooling component 500 to cool the gas in the cavity 103.

[0031] like Figure 1-Figure 5As shown, the air replenishing component 300 includes a second fixing member 301 fixedly connected to the right side of the top of the box body 101, the second fixing member 301 is communicated with the cavity 103, the second air storage shell 205 is located between the second fixing member 301 and the first fixing member 201, and two first one-way valves 3011 distributed in left and right mirror images are arranged on the lower side of the second fixing member 301, and the upper part of the left side of the second fixing member 301 is communicated with the upper side of the second air storage shell 205 through an L-shaped tube, and a second slide plate 302 is slidably connected in the second fixing member 301, and the second slide plate 302 is provided with two second one-way valves 3021 distributed in left and right mirror images. When the second slide plate 302 moves upward, the two second one-way valves 3021 are in an open state, and the inert gas on the upper side of the second slide plate 302 and the second fixing member 301 is transferred to the lower side of the second slide plate 302 and the second fixing member 301 through the upward movement of the second slide plate 302. When the second slide plate 302 moves downward , the two second one-way valves 3021 are in a closed state, and the inert gas in the second slide plate 302 and the lower side of the second fixing member 301 pushes the lower side of the second fixing member 301 into the cavity 103, thereby completing the gas replenishment of the cavity 103. In the process of the inert gas flowing through the two first one-way valves 3011, the two first one-way valves 3011 are opened, and a passage is formed between the second fixing member 301 and the cavity 103. After all the inert gas in the second fixing member 301 enters the cavity 103, the two first one-way valves 3011 are closed, so that the second fixing member 301 and the cavity 103 are no longer connected. The second connecting member 303 is fixedly connected to the upper side of the second slide plate 302, and the second connecting member 303 is sealingly and slidably matched with the second fixing member 301. The rear first rack frame 3 is fixedly connected between the second connecting member 303 and the upper side of the first connecting member 204, and the first rack frame 3 is composed of a U-shaped frame and a spur rack fixedly connected to each other.

[0032] like Figure 4-Figure 6 As shown, the deceleration assembly 400 includes a fixed frame 401 fixed to the upper side of the first fixed member 201, a fixed rod 402 fixed to the upper side of the fixed frame 401, the fixed rod 402 is provided with circumferentially distributed sliding grooves, the sliding grooves on the fixed rod 402 are composed of folding grooves distributed in a linear array, a fixed ring 403 is fixed to the upper side of the first connecting member 204, the fixed ring 403 is rotatably connected to a swivel 404, the fixed ring 403 is provided with mirror-distributed springs, the mirror-distributed springs are all in contact with the swivel 404, the swivel 404 is fixed with a circumferentially distributed elastic pin 405 on one side close to the center of the circle, the elastic pin 405 cooperates with the adjacent sliding groove on the fixed rod 402, the folding arc of the circumferentially distributed sliding groove on the fixed rod 402 in the horizontal direction is relatively large, so the elastic pin 405 will not slide along the circumferentially distributed sliding groove on the fixed rod 402 under the influence of rapid rise.

[0033] like Figure 2-Figure 4 , Figure 7 and Figure 8 As shown, the cooling component 500 includes a cooling element 501 disposed on the right side of the box body 101, the cooling element 501 is electrically connected to the control panel 1, the cooling element 501 is a refrigerator, and the cooling element 501 is connected to a first gas pipe 502 and a second gas pipe 503 that penetrates the box body 101, the first gas pipe 502 is located below the second gas pipe 503, and the first gas pipe 502 and the second gas pipe 503 are both provided with linear arrays of air holes that are distributed in a mirror image on the opposite sides, and a piston rod 504 is slidably connected to the second gas pipe 503, and the piston rod 504 is connected to the second gas pipe 503. The adjacent air holes in the air pipe 503 cooperate with each other, and the blocking position of the air holes in the second air supply pipe 503 is adjusted by adjusting the moving distance of the piston rod 504, so as to adjust the cooling efficiency of the cooling component 501 on the gas. A spring is arranged between the piston rod 504 and the second air supply pipe 503. The left side of the box body 101 is sealed and slidably connected with a first sliding frame 505 that cooperates with the piston rod 504. When the first sliding frame 505 moves to the left, it will drive the piston rod 504 to move to the left at the same time. The left side of the first sliding frame 505 is located in the cavity 103 and is connected to the first air storage The left side of the first air storage shell 104 is slidably matched, and a third slide plate 506 is slidably connected in the first air storage shell 104. A spring for resetting the third slide plate 506 is arranged between the left side of the third slide plate 506 and the first air storage shell 104. The first air storage shell 104 stores liquid located between the elastic diaphragm 105 and the third slide plate 506. The left side of the first sliding frame 505 is located in the first air storage shell 104 and is fixedly connected to the left side of the third slide plate 506. The rear side of the box body 101 is limitedly slidably connected to the second rack frame 507. The right side of the second rack frame 507 is connected to the piston rod 504 cooperates, and the piston rod 504 is driven to move to the left at the same time during the movement of the second rack rack 507 to the left.

The first gear 508 is meshed with the second rack rack 507, and the second gear 509 is meshed with the first rack rack 3. The module of the first gear 508 and the second gear 509 is consistent, and the number of teeth of the first gear 508 is less than the number of teeth of the second gear 509, which is used to amplify the movement stroke of the second rack rack 507.

[0034] Before using the device, the user needs to deliver an appropriate amount of inert gas into the cavity 103 in advance (the inert gas fills the cavity 103 with an appropriate amount of inert gas). The inert gas delivered into the cavity 103 protects the electronic components in the cavity 103 (the cavity 103 is in a high pressure state after being filled with inert gas). The inert gas in the cavity 103 is affected by the temperature inside the cavity 103 or other external environmental influences, which may cause the pressure inside the cavity 103 to exceed the pressure required for work. When the pressure inside the cavity 103 is too high, it is not conducive to the normal operation of the electronic components therein.

[0035] During use of the device, the user starts the cooling element 501 through the control panel 1, and the cooling element 501 extracts the gas in the cavity 103 through the second gas pipe 503 and re-discharges it into the cavity 103 through the first gas pipe 502. The extraction process of the second gas pipe 503: under the action of the piston rod 504 blocking the air holes of the second gas pipe 503, the second gas pipe 503 extracts the gas in the cavity 103 through the air holes on the lower right side, and the cooling element 501 cools the extracted gas and then transports it to the first gas pipe 502. The exhaust process of the first gas pipe 502: the first gas pipe 502 discharges the cooled gas therein upward from all the air holes on its upper side to achieve cooling in the cavity 103 (the electronic components in the cavity 103 will emit heat during use).

[0036] When the pressure in the cavity 103 exceeds the pressure required for work (when the load of the electronic equipment connected to the electronic components is too large, the temperature in the cavity 103 will rise rapidly, and the temperature increase will increase the pressure in the cavity 103), the pressure change in the cavity 103 squeezes the elastic diaphragm 105, and the elastic diaphragm 105 deforms to the left and expands the volume in the cavity 103, so that the pressure in the cavity 103 remains constant. After the elastic diaphragm 105 is deformed, it squeezes the liquid in the first air storage shell 104, and the third slide plate 506 is squeezed to the left through the liquid in the first air storage shell 104. During the movement of the third slide plate 506, the adjacent spring is squeezed. The third slide plate 506 drives the piston rod 504 to move to the left. During the movement of the piston rod 504, the adjacent spring is squeezed. The piston rod 504 moves to the left and gradually breaks away from the obstruction of the adjacent air hole on the second air pipe 503, thereby increasing the amount of air pumped from the second air pipe 503, thereby enhancing the cooling effect on the cavity 103.

[0037] When the pressure in the cavity 103 continues to increase (proving that the electronic component is short-circuited and damaged, and radiates heat and exhaust gas to the surroundings. Since multiple electronic components are placed in the cavity 103, when one of the electronic components is abnormal, the remaining electronic components will continue to work normally), when the pressure in the cavity 103 exceeds the deformation of the elastic diaphragm 105 and the pressure in the cavity 103 is sufficient to push the first pressure relief valve 202 open, the first pressure relief valve 202 opens and releases the excess pressure in the cavity 103 into the first fixing member 201. The gas entering the first fixing member 201 quickly pushes the first slide 203, the first connecting member 204 and the second blocking member 207 upwards, and the first slide During the movement of the plate 203, the adjacent spring is squeezed, and the second blocking member 207 blocks the left side of the adjacent L-shaped tube, so that the gas in the first fixing member 201 will not enter the adjacent L-shaped tube, and the first connecting member 204 drives the second connecting member 303 to move upward through the first rack frame 3 (the movement process of the second connecting member 303 will be described in detail later). When the force of the first connecting member 204 moving upward is greater than the supporting force provided by the two elastic pins 405, the first connecting member 204 drives the two elastic pins 405 and the parts thereon to move upward, and the two elastic pins 405 will not slide along the sliding grooves circumferentially distributed on the fixing rod 402. Through the above description, the pressure relief in the cavity 103 is completed.

[0038] During the pressure relief of the cavity 103, the first connecting member 204 drives the first rack 3 and the second connecting member 303 to move upward, and the two second one-way valves 3021 are in an open state. Through the upward movement of the second slide 302, the inert gas between the upper sides of the second slide 302 and the second fixing member 301 is squeezed to between the lower sides of the second slide 302 and the second fixing member 301, thereby completing the transfer of the inert gas.

[0039] When the inert gas in the second fixing member 301 is transferred, the first rack 3 moves upward and drives the first gear 508 to rotate. The first gear 508 drives the second gear 509 to rotate through the adjacent rotating shaft. The first gear 508 drives the second rack 507 to move leftward. The second rack 507 drives the piston rod 504 to continue to move leftward. The piston rod 504 squeezes the adjacent spring. The piston rod 504 moves leftward and gradually breaks away from the obstruction of the adjacent air hole on the second air pipe 503, and continues to increase the amount of air pumped from the second air pipe 503, and continues to enhance the cooling effect on the cavity 103. The above description is a description of the pressure relief process of the cavity 103.

[0040] When the pressure in the cavity 103 is released, the first pressure relief valve 202 remains closed to block the upper left side of the cavity 103. The second blocking member 207 slides downward after losing the impact of the gas during pressure relief to break away from the blockage of the adjacent L-shaped tube. The first slide plate 203 and the first connecting member 204 drive the first rack 3 and the parts thereon to slide downward under the action of the adjacent springs. During the downward movement of the first slide plate 203, the exhaust gas discharged from the cavity 103 in the first fixing member 201 is pushed into the adjacent L-shaped tube. The second pressure relief valve 206 in the adjacent L-shaped tube of the first fixing member 201 is Under the action, the downward sliding speed of the first slide plate 203 is buffered, and the exhaust gas is compressed and flows into the adjacent L-shaped tube (the downward sliding speed of the first connecting member 204 is reduced by buffering), and the exhaust gas entering the adjacent L-shaped tube pushes open the second pressure relief valve 206, so that the gas enters the second gas storage shell 205 from the adjacent L-shaped tube, and the exhaust gas flowing through the adjacent L-shaped tube is filtered by the filter element 2, so that the gas entering the second gas storage shell 205 is in a clean state, and the gas discharged from the cavity 103 is collected by the second gas storage shell 205, so that the gas does not flow into the outside air.

[0041] The purpose of reducing the downward sliding speed of the first connecting member 204 is to extend the time for the cooling member 501 to cool the gas in the cavity 103. During the downward sliding process of the first connecting member 204, the two elastic pins 405 thereon slide along the circumferentially distributed sliding grooves on the fixed rod 402. The sliding grooves on the fixed rod 402 are folded, so the downward sliding speed of the first connecting member 204 is further reduced, and the time for the cooling member 501 to cool the gas in the cavity 103 is further extended. When the elastic pin 405 slides to the fold of the adjacent sliding groove on the fixed rod 402, the swivel 404 drives the two elastic pins 405 thereon to rotate along the swivel 404 and squeeze the spring on the same side as the rotating side. When the elastic pin 405 no longer slides to the fold of the adjacent sliding groove on the fixed rod 402, the swivel 404 is driven to reset by the spring on the same side as the rotating side.

[0042] When the excess gas in the cavity 103 is discharged and gas replenishment is required, the first connecting member 204 slides downward and drives the first rack 3 and the second connecting member 303 to move downward. The second connecting member 303 drives the second slide plate 302 to slide downward so that the two second one-way valves 3021 remain in a closed state. The second slide plate 302 moves downward to squeeze it and the inert gas in the lower side of the second fixing member 301 downward. The first one-way valve 3011 is pushed open by the inert gas squeezed downward, so that a passage is formed between the second fixing member 301 and the cavity 103, and the inert gas enters the cavity 103 from the lower side of the second fixing member 301, thereby completing the gas replenishment of the cavity 103. During the downward movement of the second slide plate 302, the gas in the second gas storage shell 205 is re-drawn to between the second slide plate 302 and the upper side of the second fixing member 301 through the adjacent L-shaped tube.

[0043] During the process of replenishing air to the cavity 103, the first rack rack 3 moves downward and drives the first gear 508 and the second gear 509 to rotate. The first gear 508 rotates and drives the second rack rack 507 to move to the right. During the movement of the second rack rack 507 to the right, it gradually breaks away from the squeezing of the piston rod 504. The piston rod 504 drives the first sliding rack 505 to move to the right through the adjacent spring. During the movement of the piston rod 504 to the right, it gradually blocks the air hole on the right side of the second air pipe 503, thereby reducing the air suction volume of the second air pipe 503.

[0044] After the air supply to the cavity 103 is completed, the first slide plate 203 has been pushed to the basic state by the adjacent spring (the basic state is Figure 4 For example, the first slide plate 203 is located at the lower side of the first fixing member 201 near the first pressure relief valve 202), the first slide plate 203 stops moving after sliding to the basic state, at this time the second pressure relief valve 206 remains closed, so that the first fixing member 201 and the adjacent L-shaped tube are no longer interconnected, the second slide plate 302 slides to the position close to the first one-way valve 3011 in the second fixing member 301 and stops moving, at this time the two first one-way valves 3011 are in a closed state, so that the second fixing member 301 and the cavity 103 are no longer interconnected, the exhaust gas discharged from the cavity 103 is collected and filtered through the above steps, and the inert gas is re-delivered into the cavity 103, and the cooling member 501 is used to cool the remaining gas in the cavity 103 to complete the cooling of the gas in the cavity 103 while keeping the volume of the gas therein unchanged.

[0045] After the temperature of the gas in the cavity 103 reaches the required working temperature, the elastic diaphragm 105 deforms and resets to the right. Under the action of the adjacent spring of the third slide plate 506, it moves to the right and squeezes the liquid in the first air storage shell 104, so that the liquid in the first air storage shell 104 squeezes the elastic diaphragm 105, and the elastic diaphragm 105 returns to the state before deformation.

[0046] After the above actions are completed, the user will repair the abnormal electronic components, and the maintenance process is as follows: before the user repairs the electronic components in the cavity 103, the user turns off the cooling component 500 through the control panel 1, and then the user extracts and collects the inert gas in the cavity 103, and finally the user removes the sealing plate 102, and then repairs the abnormal electronic components in the cavity 103. After the maintenance is completed, the sealing plate 102 is reassembled into the box body 101, and then the inert gas is re-injected into the cavity 103.

When the electronic components in the cavity 103 need to be repaired, the solenoid valve 603 is opened and the adjacent L-shaped tube is no longer blocked. The gas storage member 602 forms a passage with the cavity 103 through two L-shaped tubes. The tension spring adjacent to the gas storage member 602 pulls the gas storage member 602 upward. Under the action of the negative pressure environment in the gas storage member 602, the high-pressure gas in the cavity 103 is extracted for collection.

[0048] like Figure 2 and Fig. 9As shown, it also includes a locking assembly 700 arranged on the box body 101, and the second sliding frame 605 is locked to the middle part of the limiting rod 604 by the locking assembly 700, so that the second sliding frame 605 maintains the extrusion state of the gas storage member 602, and the locking assembly 700 includes two elastic limiting members 701 distributed in left and right mirror images, and the two elastic limiting members 701 distributed in left and right mirror images are both fixed to the lower side of the box body 101, and the opposite sides of the two elastic limiting members 701 distributed in left and right mirror images are provided with inclined surfaces, and the inclined surfaces on both sides of the second sliding frame 605 are both aligned with the two elastic limiting members 701 distributed in left and right mirror images. 01's inclined surface is squeezed and matched, the mirror-distributed elastic limit members 701 are all limited and matched with the second sliding frame 605, when the upper side of the second sliding frame 605 contacts the lower sides of the two elastic limit members 701 distributed in the left and right mirror images, the second sliding frame 605 is limited, the box body 101 is slidably connected with the third sliding frame 702, and the back side of the lower side of the third sliding frame 702 is provided with inclined surfaces, the inclined surfaces on the back sides of the two elastic limit members 701 in the left and right mirror images are squeezed and matched with the inclined surfaces on the back side of the lower side of the third sliding frame 702, and a spring is provided between the third sliding frame 702 and the box body 101.

[0049] like Fig. 9 and Fig.10 As shown, a buffer component 8 is fixedly connected to the upper side of the limiting rod 604. The buffer component 8 is located above the second sliding frame 605. The buffer component 8 cooperates with the upper side of the second sliding frame 605. The buffer component 8 is used to buffer the second sliding frame 605. The buffer component 8 is provided with a linear array of pores distributed circumferentially.

[0050] Before using the device, the user connects the external air pump to the gas storage member 602, and then the user presses the second sliding frame 605 downward. During the pressing of the second sliding frame 605, the user controls the external air pump to extract the gas in the gas storage member 602, and the second sliding frame 605 moves downward to squeeze the gas in the gas storage member 602 and make the gas storage member 602 shrink and move downward (the adjacent tension springs are stretched during the shrinking process of the gas storage member 602). When the second sliding frame 605 moves to the point where its two sides contact the two elastic stoppers 701, the user continues to press the second sliding frame 605 to make the second sliding frame 605 squeezes the telescopic parts on the two elastic limit members 701 to both sides, and after the second sliding frame 605 continues to move downward so that its upper side contacts the lower sides of the two elastic limit members 701, the two elastic limit members 701 limit the second sliding frame 605, so that the second sliding frame 605 will not move upward at will, and the user no longer presses the second sliding frame 605 downward, and then the user controls the external vacuum pump to no longer extract the gas in the gas storage member 602. At this time, a negative pressure environment has been formed in the gas storage member 602. The above process is the preparation work before using the present device, and the working state of the present device is consistent with the above.

[0051] Before the user repairs the electronic components in the cavity 103, the user needs to first extract the high-pressure gas in the cavity 103 to avoid the cavity 103 being in a high-pressure environment when the user repairs the cavity 103, causing the user to be impacted by the high-pressure gas in the cavity 103, thereby threatening the user's personal safety. The process of extracting the high-pressure gas is as follows: the user first opens the two solenoid valves 603 through the control panel 1, so that the cavity 103 is connected to the gas storage member 602 through the adjacent L-shaped tubes. Under the action of the negative pressure environment in the gas storage member 602, the high-pressure gas in the cavity 103 is extracted into the gas storage member 602 through the two adjacent L-shaped tubes, and then the user presses the third sliding frame 702 downward (the third sliding frame 702 is pushed downward). During the downward movement, the adjacent springs are squeezed), and the lower side of the third sliding frame 702 squeezes the two elastic limiting members 701 to both sides until it is disengaged from the limiting position of the second sliding frame 605 (after the third sliding frame 702 is disengaged from the contact with the two elastic limiting members 701, it is reset upward through the adjacent springs), and the upper side of the second sliding frame 605 and the gas storage member 602 are driven to move upward under the action of the adjacent tension springs of the second sliding frame 605. Through the reset movement of the gas storage member 602, the high-pressure gas in the cavity 103 is drawn into the gas storage member 602 through the two adjacent L-shaped tubes, thereby shortening the time for forming a normal pressure environment (consistent with the external pressure) in the cavity 103, and quickly transferring the high-pressure gas in the cavity 103 to the gas storage member 602.

[0052] When the high-pressure gas in the cavity 103 is completely transferred to the gas storage member 602, the user closes the two solenoid valves 603 through the control panel 1, so that the cavity 103 is no longer connected to the gas storage member 602 through the adjacent L-shaped tube. When the second sliding frame 605 is pulled upward and reset by the adjacent tension spring, the second sliding frame 605 moves to the upper side of the limit rod 604 and contacts the two buffer members 8. When the second sliding frame 605 squeezes the two buffer members 8, the two buffer members 8 are squeezed and the gas therein is discharged from all the air holes thereon to achieve buffering of the second sliding frame 605, and prevent the second sliding frame 605 from moving upward too fast, causing the second sliding frame 605 to collide with the upper sides of the two limit rods 604 and cause wear or damage to both. Through the above process, the transfer of gas in the cavity 103 is achieved.

[0053] After completing the transfer of the high-pressure gas in the cavity 103 , the user pulls out the first sealing member 1021 until it is no longer in contact with the sealing plate 102 , allowing external gas to enter the cavity 103 to form a positive pressure environment, and then the user removes the sealing plate 102 to repair the electronic components in the cavity 103 .

[0054] After completing the repair of the electronic components in the cavity 103, the user first inserts the first sealing member 1021 into the sealing plate 102, and then reinstalls the sealing plate 102 to the front side of the box 101. Finally, the user controls the external vacuum equipment to evacuate the cavity 103 to a negative pressure environment.

[0055] When a negative pressure environment is formed in the cavity 103, the user starts the two solenoid valves 603 through the control panel 1, so that the cavity 103 is connected with the gas storage component 602 through the adjacent L-shaped tubes. Under the action of the negative pressure environment in the cavity 103, the high-pressure gas in the gas storage component 602 enters the cavity 103 through the two adjacent L-shaped tubes. During the transfer of the high-pressure gas, the user presses the second sliding frame 605 downward to limit it with two elastic limiting members 701. During the downward movement of the second sliding frame 605, the gas storage component 602 is squeezed, so that the gas in the gas storage component 602 quickly enters the cavity 103 through the two adjacent L-shaped tubes to complete the filling of the gas in the cavity 103.

[0056] When all the gas in the gas storage member 602 enters the cavity 103, the user closes the two solenoid valves 603 through the control panel 1 so that the cavity 103 is no longer connected to the gas storage member 602 through the adjacent L-shaped tube. The user then replenishes inert gas into the cavity 103 to restore the high-pressure environment in the cavity 103.
