[0039] Please refer to Figure 4 and Figures 6-7 , vertical bulkhead 3 is distributed in linear array along the extension direction of transverse bulkhead 2, the bottom is inclined, guide inclined rod 10 is fixedly installed above the back of inclined plate 5 near both sides, adjusting motor 11 is fixedly installed above the back of inclined plate 5 between guide inclined rod 10, one end of output shaft of adjusting motor 11 is fixedly installed with adjusting screw rod 12, sliding plate 13 is sleeved on the outer surface of adjusting screw rod 12 in threaded cooperation, in the process of driving adjusting screw rod 12 to rotate by adjusting motor 11, sliding plate 13 is driven to move in threaded cooperation, sliding plate 13 is matched with guide inclined rod 10 in shaft hole sliding cooperation, sliding groove 14 is opened in the bottom surface of inclined plate 5, pressure sensing seat 15 is arranged at the bottom of sliding plate 13, pressure sensing seat 15 extends below inclined plate 5 through sliding groove 14, first spring rod 16 is movably installed on pressure sensing seat 15 in shaft hole cooperation;

[0040] The output end of pressure sensing seat 15 is connected with the input end of air cooler 9 in signal connection.

[0041] Please refer to Figures 8-9The bottom of the first spring rod 16 is fixedly provided with a mounting box 17, the mounting box 17 is driven to move simultaneously with the pressure sensing seat 15, the inside of the mounting box 17 is provided with a mounting rack 18, the front of the mounting rack 18 is fixedly provided with an electrical equipment 19, the tail seat 20 is arranged on the back of the mounting box 17 close to both sides, the outer side of the tail seat 20 is provided with a gas guide hole 21, the gas guide hole 21 is connected with the inner cavity of the mounting box 17, and the screw coil 22 is arranged on the back of the tail seat 20 close to the top.

[0042] By adjusting the motor 11 to drive the adjusting screw rod 12 to rotate, the sliding plate 13 and the mounting box 17 are driven to move synchronously in a threaded manner, when the maintenance personnel needs to install the electrical equipment 19 in the inside of the mounting box 17 or daily overhauls the electrical equipment 19, the adjusting motor 11 is controlled to drive the mounting box 17 to move towards the front of the ring network box body 1, so that the mounting box 17 can be closer to the maintenance personnel, the inside of the mounting box 17 is conveniently operated by the personnel, the problem that the space is narrow when the mounting box 17 is too close to the inside of the ring network box body 1 during installation, maintenance and overhaul, and operation is difficult is avoided, and the practicability of the device is improved.

[0043] Since the pressure sensing seat 15 and the first spring rod 16 are in the state of active installation, and the guide inclined rod 10 is in an inclined state, the self-weight of the mounting box 17 generates a component force in the direction of the first spring rod 16, and the component force is balanced with the elastic force stored in the first spring rod 16, when the electrical equipment 19 is installed in the inside of the mounting box 17, the self-weight of the mounting box 17 increases, so that the sliding plate 13 further moves towards the adjusting motor 11, at this time, the tail seat 20 passes through the matching hole 64 and pushes open the spring flap 65, since the gas guide hole 21 extends into the back side of the air duct plate 61, the cold air generated by the air cooler 9 can enter the inside of the mounting box 17 through the gas guide hole 21, so that the heat dissipation effect of the electrical equipment 19 is realized, the problem that the working temperature of the electrical equipment 19 is too high to cause thermal runaway is avoided, and as the number of the electrical equipment 19 installed in the inside of the mounting box 17 increases, the self-weight of the mounting box 17 also increases, so that the volume of the part of the tail seat 20 extending into the back side of the air duct plate 61 increases, the wind area of the gas guide hole 21 increases, the amount of cold air entering the inside of the mounting box 17 increases, the cooling efficiency of the electrical equipment 19 also increases, when the number of the electrical equipment 19 in the inside of the mounting box 17 increases and the heat generated by the electrical equipment 19 increases, the cooling efficiency also increases, the electrical equipment 19 is ensured to be at the best working temperature, and the problem that the temperature excessively accumulates to cause thermal runaway is avoided.

[0044] When the number of electrical equipment 19 increases or the load increases, the first spring rod 16 is pressed with increased force, and the pressure sensing seat 15 is also pressed with increased force. At this time, the output end of the pressure sensing seat 15 is connected to the input end of the air cooler 9 through signal connection, so that when the pressure sensing seat 15 is pressed with increased force, the power of the air cooler 9 is controlled to increase synchronously, so that the amount of cold air generated increases, and the heat dissipation efficiency of the air cooler 9 can increase synchronously when the number of electrical equipment 19 is large or the electrical equipment 19 is in high-power operation, so that the heat dissipation efficiency of the device is ensured, and the air cooler 9 is always in the best operating power.

[0045] Please refer to Figures 10-11 , the air duct device 6 includes an air duct plate 61, a water storage device 62 is arranged on the back of the air duct plate 61 near the top, an air duct partition plate 63 is arranged on the back of the air duct plate 61 near the middle, a matching hole 64 is formed on the back of the air duct plate 61 between the water storage device 62 and the air duct partition plate 63 and below the air duct partition plate 63, a spring flap 65 is arranged on the back of the air duct plate 61 corresponding to the matching hole 64, and a side plate 66 is fixedly installed on the back of the air duct plate 61 between the water storage device 62 and the air duct partition plate 63 and below the air duct partition plate 63. The front of the side plate 66 is connected to the water storage device 62 through a pipeline.

[0046] Please refer to Figures 10-14 , the water storage device 62 includes a water storage tank 621 for storing rainwater, and a cooling pipe 622 is arranged in the water storage tank 621, the cooling pipe 622 is connected to one end of the side plate 66, a water leakage hole 623 is formed on the front of the inner wall of the water storage tank 621, and a switch motor 624 is fixedly installed on one side of the inner cavity of the water storage tank 621, and a hole sealing baffle 625 is fixedly installed on one end of the output shaft of the switch motor 624.

[0047] The hole sealing baffle 625 blocks the water leakage hole 623 in the initial state, and after the hole sealing baffle 625 is opened, rainwater enters the gap between the vertical partition plates 3 through the water leakage hole 623.

[0048] When an overload occurs, the magnetic force generated by the screw coil 22 reaches the maximum, and the attraction force received by the permanent magnet 243 reaches the maximum, so that the trigger seat 244 is in contact with the back of the tail seat 20. At this time, the output end of the trigger seat 244 is connected to the switch motor 624 through signal connection, and the switch motor 624 drives the hole sealing baffle 625 to rotate, so that the rainwater stored in the water storage tank 621 enters the gap between the vertical partition plates 3 through the water leakage hole 623, and the water flow is used to dissipate heat in the inner cavity of the mounting box 17, so that when the contact between the trigger seat 244 and the back of the tail seat 20 causes the heat dissipation efficiency of the mounting box 17 to reach the maximum, the water flow can be used to supplement the heat dissipation.

[0049] The cold air generated by the air cooler 9 will enter the inside of the cooling pipe 622 through the channel outside the side plate 66 after passing through all the installation boxes 17, so as to cool the rainwater stored in the water storage box 621, ensure that the rainwater in the water storage box 621 is at a lower temperature, and ensure that the temperature of the rainwater can be normally cooled when the rainwater enters the gap between the vertical partitions 3 through the drain hole 623.

[0050] Please refer to Figure 3 The front of the tail box 7 is provided with a stroke box 23, and a stroke device 24 is movably installed in the inside of the stroke box 23.

[0051] Please refer to Figures 8-9 The stroke device 24 comprises a stroke seat 241, a second spring rod 242 is fixedly installed on the back of the stroke seat 241, springs provided on the outer surface of the second spring rod 242 are connected with the stroke box 23, a permanent magnet 243 is provided on the front of the stroke seat 241 and close to the top, and a trigger seat 244 is provided on the front of the stroke seat 241 and close to the bottom.

[0052] The output end of the trigger seat 244 is connected with the switch motor 624 in a signal connection mode.

[0053] When the electricity peak is reached, the outer surface of the screw coil 22 is wound with the power supply circuit, the screw coil 22 generates a magnetic force during the operation of the device, and an adsorption force is generated with the permanent magnet 243. At this time, the current intensity in the power supply circuit is increased, the magnetic force intensity generated by the screw coil 22 is increased, the attraction force received by the permanent magnet 243 is increased, the spacing between the stroke seat 241 and the tail seat 20 is reduced, which makes the resistance of the cold air generated by the air cooler 9 increased when passing through, so that more cold air enters the inside of the installation box 17 through the air guide hole 21, thereby further improving the heat dissipation capacity of the inside of the installation box 17. When the electricity peak is reached, the current intensity in the power supply circuit is increased and the heat generation is increased, the cooling efficiency of the electrical equipment 19 can be further improved, and the electrical equipment 19 can still be in a normal working state under high load.

[0054] Please refer to Figures 8-9 and Figure 10 The tail seat 20 is corresponding to the matching hole 64, and the tail seat 20 will be inserted into the inside of the matching hole 64 after the installation box 17 slides down along the guide inclined rod 10.

[0055] Please refer to Figure 9 and Figures 15-16 The outer surface of the screw coil 22 is wound with the power supply circuit, and the screw coil 22 generates a magnetic force during the operation of the device, and an adsorption force is generated with the permanent magnet 243.

[0056] Please refer toFigures 3-4 and Figure 10 The air outlet of the air cooler 9 corresponds to the air duct between the air duct plate 61 and the stroke box 23.

[0057] The method of use of the present application is as follows:

[0058] In use, the operator and the maintenance personnel need to install, maintain or repair the electrical equipment 19, by adjusting the motor 11 to drive the adjusting screw rod 12 to rotate, and through the threaded cooperation to drive the sliding plate 13 and the installation box 17 to move synchronously, when the maintenance personnel need to install the electrical equipment 19 in the inside of the installation box 17, or carry out daily maintenance and repair to the electrical equipment 19, the control of the adjusting motor 11 and the driving of the installation box 17 to move towards the front face of the ring network box body 1 can make it closer to the maintenance personnel, and facilitate the personnel to operate the inside of the installation box 17, because the pressure sensing seat 15 and the first spring rod 16 are in the state of active installation, and the guide inclined rod 10 is in the state of inclination, the weight of the installation box 17 generates a component force along the direction of the first spring rod 16, and the component force is balanced with the elastic force stored in the first spring rod 16, when the electrical equipment 19 is installed in the inside of the installation box 17, at this time the weight of the installation box 17 increases, so that the sliding plate 13 further moves towards the direction of the adjusting motor 11, at this time the tail seat 20 passes through the matching hole 64 and pushes open the spring flap 65, because the air guide hole 21 extends into the rear side of the air duct plate 61, the cold air generated by the air cooler 9 can enter into the inside of the installation box 17 through the air guide hole 21, so as to realize the heat dissipation effect of the electrical equipment 19, avoid the problem of thermal runaway caused by the high working temperature of the electrical equipment 19, and as the number of the electrical equipment 19 installed in the inside of the installation box 17 increases, the weight of the installation box 17 also increases, so that the volume of the part of the tail seat 20 extending into the rear side of the air duct plate 61 increases, at the same time the wind receiving area of the air guide hole 21 increases, so that the amount of cold air entering into the inside of the installation box 17 increases, and the cooling efficiency of the electrical equipment 19 also increases at the same time, when the number of the electrical equipment 19 in the inside of the installation box 17 increases and the heat generated by the working increases, the cooling efficiency also increases at the same time, so as to ensure that the electrical equipment 19 is in the best working temperature, when in the power peak, because the outer surface of the screw coil 22 is wound with the power supply circuit, the screw coil 22 generates magnetic force when the device operates, and generates attraction force with the permanent magnet 243, at this time the current intensity in the power supply circuit increases, so that the magnetic force intensity generated by the screw coil 22 increases, at this time the attraction force received by the permanent magnet 243 increases, so that the spacing between the travel seat 241 and the tail seat 20 decreases, which makes the cold air generated by the air cooler 9 increase the resistance when passing, so as to realize that more cold air enters into the inside of the installation box 17 through the air guide hole 21, thereby further improving the heat dissipation capacity in the inside of the installation box 17, when in the power peak, the current intensity in the power supply circuit increases and the heat increases, the cooling efficiency of the electrical equipment 19 also can be further improved, so as to ensure that the electrical equipment 19 can still be in the normal working state under high load, when the number of the electrical equipment 19 increases or the load increases, the degree of compression of the first spring rod 16 increases, at the same time the pressure received by the pressure sensing seat 15 also increases synchronously,At this time, the output end of the pressure sensing seat 15 is connected to the input end of the air cooler 9 through signal connection, so that when the pressure sensing seat 15 is pressed with higher force, the power of the air cooler 9 is controlled to increase synchronously, so that the amount of cold air generated is increased, and when there are more electrical equipment 19 or the electrical equipment 19 is in high-power operation, the heat dissipation efficiency of the air cooler 9 can be increased synchronously.

[0059] When the overload occurs, the magnetic force generated by the screw coil 22 reaches the maximum, and the attraction force of the permanent magnet 243 reaches the maximum, so that the trigger seat 244 is in contact with the back of the tail seat 20. At this time, the output end of the trigger seat 244 is connected to the switch motor 624 through signal connection, and the switch motor 624 drives the sealing baffle 625 to rotate, so that the rainwater stored in the water storage tank 621 enters the gap between the vertical partition plates 3 through the drain hole 623. The inside of the mounting box 17 is cooled by the water flow, and when the trigger seat 244 is in contact with the back of the tail seat 20, the cooling efficiency of the mounting box 17 is maximized, and the water flow can be used for supplementary cooling. After the cold air generated by the air cooler 9 passes through all the mounting boxes 17, it enters the inside of the cooling pipe 622 through the channel outside the side plate 66, thereby cooling the rainwater stored in the water storage tank 621, so that the rainwater in the water storage tank 621 is in a lower temperature state, and when the rainwater enters the gap between the vertical partition plates 3 through the drain hole 623, it can be normally cooled.
