Description

Technical Field

[0001] This invention belongs to the field of energy storage power technology, specifically relating to a wall-mounted energy storage power supply with high efficiency in charging and discharging. Background Technology

[0002] Energy storage power supplies, also known as "outdoor power supplies" or "portable power stations," are large mobile power supplies that integrate high-capacity lithium batteries, inverters, charging management systems, and multiple output interfaces. Essentially, they are small, portable, and clean "home power grids" that can convert stored electrical energy into the power needed by various devices. The biggest difference between them and traditional small power banks is that they have high power, large capacity, and a full range of interfaces, enabling them to power a variety of electrical appliances, from mobile phones and laptops to rice cookers, refrigerators, and even power tools.

[0003] Currently, existing wall-mounted energy storage power supplies experience temperature rise during charging and discharging due to the operation of their internal inverters and battery cells. This causes current limitation during charging and discharging, resulting in a decrease in charging and discharging power and affecting the lifespan of the power supply. Therefore, this paper proposes a wall-mounted energy storage power supply with high-efficiency charging and discharging. Summary of the Invention

[0004] The purpose of this invention is to provide a reasonably designed, high-efficiency wall-mounted energy storage power supply for charging and discharging in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A high-efficiency charging and discharging wall-mounted energy storage power supply includes a housing and two power blocks installed inside the housing. A cover is bolted to the housing, and a touchscreen is fixedly connected to the cover. A bracket is fixedly connected to the back of the housing, and louvers are installed on the top of the housing. A circuit board is fixedly connected inside the housing, and a socket is fixedly connected to the bottom of the circuit board, passing through the housing. A mounting plate is fixedly connected inside the housing, and the power blocks are bolted to the mounting plate. The power supply also includes: A heat dissipation mechanism that is fixedly connected inside the enclosure; A cooling mechanism is fixedly connected inside the housing and located on the outer surface of the power block, with the exhaust end of the heat dissipation mechanism facing the cooling mechanism.

A switch mechanism is fixedly connected inside the housing. The switch mechanism is driven by an inspection mechanism. When one of the upper inspection section, middle inspection section, and lower inspection section breaks, the inspection mechanism drives the switch mechanism to block the cooling mechanism. When the upper inspection section, middle inspection section, and lower inspection section are tightened simultaneously, the inspection mechanism drives the switch mechanism to open the cooling mechanism.

[0006] As a further optimization of the present invention, the cooling mechanism includes a liquid tank fixedly connected to the housing, a vent channel fixedly connected inside the liquid tank, a pump body fixedly connected to the liquid tank, a heat exchange tube fixedly connected to the discharge end of the pump body, the heat exchange tube being fixedly connected to the housing through a fixed pipe bracket, and a return pipe fixedly connected to the end of the heat exchange tube, the return pipe being fixedly connected to the liquid tank.

[0007] As a further optimization of the present invention, the heat exchange tube is fixedly connected to a liquid spraying pipe at the part below the power supply block, and the liquid spraying pipe is provided with spray holes.

[0008] As a further optimization of the present invention, the heat dissipation mechanism includes an exhaust pipe fixedly connected to the housing, the exhaust pipe being fixedly connected to the liquid tank, the exhaust end of the exhaust pipe being positioned directly opposite the ventilation channel and communicating with the interior of the ventilation channel, a filter screen being fixedly connected to the inlet end of the exhaust pipe, an outlet being provided on the exhaust pipe, a mounting bracket being fixedly connected inside the exhaust pipe, a motor being fixedly connected to the mounting bracket, a rotating shaft being fixedly connected to the output end of the motor, fan blades being fixedly connected to the outer surface of the rotating shaft, and the rotating shaft being rotatably connected to the mounting bracket.

[0009] As a further optimization of the present invention, the inspection mechanism further includes a fixed frame fixedly connected to the box body, a connecting plate fixedly connected to the box body, and the upper inspection part, middle inspection part and lower inspection part are all fixedly connected to the box body.

[0010] As a further optimization of the present invention, the upper inspection section includes an upper fixing plate fixedly connected to the box body. An upper inspection rope is fixedly connected to one side of the upper fixing plate. The upper inspection rope slides through the fixing frame. An upper guide rope plate is fixedly connected to the box body. An upper guide cylinder is fixedly connected to the upper guide rope plate. The upper inspection rope passes through the upper guide rope plate and is slidably connected to the upper guide cylinder. An upper push frame is fixedly connected to the end of the upper inspection rope. An upper push spring is fixedly connected to the upper push frame. An upper roller is rotatably connected to the end of the upper push frame. The upper push spring is fixedly connected to the connecting plate.

[0011] As a further optimization of the present invention, the intermediate inspection section includes an intermediate fixing plate fixedly connected to the box body, an intermediate inspection rope fixedly connected to the intermediate fixing plate, the intermediate inspection rope being slidably connected to the fixing frame, an intermediate push frame fixedly connected to the end of the intermediate inspection rope, an intermediate push spring fixedly connected to one end of the intermediate push frame, the intermediate push spring being fixedly connected to the fixing frame, and an intermediate roller rotatably connected to the other end of the intermediate push spring.

[0012] As a further optimization of the present invention, the lower inspection section includes a lower fixing plate fixedly connected to the box body, a lower inspection rope fixedly connected to the lower fixing plate, a lower guide rope plate fixedly connected to the box body, a lower guide cylinder fixedly connected to the lower guide rope plate, the lower inspection rope passing through the lower guide rope plate and slidably connected to the lower guide cylinder, a lower push frame fixedly connected to the end of the lower inspection rope, a lower roller fixedly connected to the end of the lower push frame, a lower push spring fixedly connected to the lower push frame, and the lower push spring fixedly connected to the connecting plate.

[0013] As a further optimization of the present invention, the switching mechanism includes multiple telescopic rods fixedly connected to the housing. A push plate is fixedly connected to the end of each telescopic rod. A connecting spring is sleeved on the telescopic rod located in the middle. The two ends of the connecting spring are fixedly connected to the push plate and the housing, respectively. A push block is fixedly connected to one side of the push plate. The push block has three push grooves, which are adapted to the upper push frame, the middle push frame, and the lower push frame, respectively. A sealing plate is fixedly connected to one side of the push plate located on the push block. A sealing chamber is fixedly connected to one side of the heat exchange tube. The sealing plate and the sealing chamber are slidably connected.

[0014] The beneficial effects of this invention are as follows: 1. This invention utilizes a cooling mechanism and a perfluoroketone solution. When the perfluoroketone flows through the heat exchange tube, it dissipates heat from the power block, thus reducing the temperature impact on the power block's charging and discharging process. Furthermore, during this process, air entering the extraction pipe enters the ventilation channel and is then discharged through the top of the ventilation channel. This allows outside air to dissipate heat from the perfluoroketone liquid in the tank after it has absorbed heat from the power block, further improving the heat dissipation efficiency of the power block and consequently enhancing the charging and discharging efficiency of the energy storage power supply.

[0015] 2. By designing a heat dissipation mechanism, this invention achieves cooling of the power supply block, circuit board, and touch screen during charging and discharging, preventing the power supply block from overheating and thus limiting the current during charging and discharging, thereby improving the charging and discharging power of the energy storage power supply.

[0016] 3. This invention, through the setting of an upper inspection section, a middle inspection section, and a lower inspection section, ensures that regardless of which part of the power block catches fire, the sealing plate will enter the heat exchange tube to seal it. This increases the pressure between the sealed part of the heat exchange tube and the discharge end of the pump body. When the pressure exceeds the opening pressure of the overflow valve in the spray pipe, the overflow valve opens, allowing the spray nozzle to spray perfluoroketone liquid into the power block and the tank. The perfluoroketone liquid is then atomized in the tank through the spray nozzle. Furthermore, when a fire occurs inside the energy storage power supply, the power supply is in operating mode, i.e., the evacuation pipe is in evacuation mode, which will allow the gas inside the tank to circulate, thereby filling the tank with the atomized perfluoroketone liquid. After a period of time, when the motor is turned off, the tank will be filled with perfluoroketone liquid, thus realizing the fire extinguishing operation of the power block, improving the timeliness of fire extinguishing, and achieving good protection for the energy storage power supply.

[0017] 4. Through the design of the switching mechanism, this invention ensures that when the energy storage power supply is repaired after a fire, the pushing block will only be able to pull the sealing plate away from the heat exchange tube under the action of the connecting spring when the upper, middle, and lower inspection ropes are all tightened, preventing the upper, middle, and lower push frames from moving the pushing block. This allows for timely fire extinguishing of the energy storage power supply regardless of which part of the power block catches fire, ensuring the safety of the energy storage power supply during operation.

Detailed Implementation

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 12As shown, a high-efficiency charging and discharging wall-mounted energy storage power supply includes a housing 1 and two power blocks 8 installed inside the housing 1. A cover 2 is fixedly connected to the housing 1 by bolts, and a touch screen 3 is fixedly connected to the cover 2. The touch screen 3 is existing technology and is used to control the operation of the energy storage power supply. A bracket 4 is fixedly connected to the back of the housing 1, and a louver 5 is installed on the top of the housing 1. A circuit board 6 is fixedly connected inside the housing 1. The circuit board 6 is electrically connected to the power blocks 8 and the touch screen 3. A socket 7 is fixedly connected to the bottom of the circuit board 6. Multiple sockets 7 are provided for charging and discharging operations. The sockets 7 pass through the housing 1. A mounting plate 9 is fixedly connected inside the housing 1, and the power blocks 8 are fixedly connected to the mounting plate 9 by bolts.

[0022] During charging, the charging device is connected to the power grid through the socket 7, and the power block 8 can be charged through the circuit board 6. During discharging, the energy storage power is connected to the electrical device through the socket 7, and the discharge power is adjusted through the touch screen 3. During the charging and discharging process, the touch screen 3 always displays the charging and discharging power, so that the user can clearly understand the charging and discharging power.

[0023] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a heat dissipation mechanism 10 is fixedly connected inside the housing 1. The heat dissipation mechanism 10 includes an exhaust pipe 101 fixedly connected to the housing 1. A filter screen 102 is fixedly connected to the air inlet end of the exhaust pipe 101. The filter screen 102 is used to filter the air entering the housing 1. An air outlet 103 is provided on the exhaust pipe 101. Multiple air outlets 103 are provided, and one of them is set directly opposite the circuit board 6. A mounting bracket 104 is fixedly connected inside the exhaust pipe 101. A motor 105 is fixedly connected to the mounting bracket 104. A rotating shaft 106 is fixedly connected to the output end of the motor 105. A fan blade 107 is fixedly connected to the outer surface of the rotating shaft 106. The rotating shaft 106 is rotatably connected to the mounting bracket 104.

[0024] During the charging and discharging process, the starting motor 105 causes the rotating shaft 106 to drive the fan blades 107 to rotate, which in turn causes the air extraction pipe 101 to draw in the outside air filtered by the filter screen 102 and enter the air extraction pipe 101, and then discharge it into the housing 1 through the air outlet 103. Then the outside air will flow upward through the power block 8 and finally be discharged to the outside through the louver 5. This achieves the cooling operation of the power block 8, the circuit board 6 and the touch screen 3, and avoids the high temperature of the power block 8, which would limit the current during the charging and discharging process of the energy storage power supply, thereby improving the charging and discharging power of the energy storage power supply.

[0025] like Figure 3 , Figure 4 , Figure 5, Figure 6 , Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, a cooling mechanism 11 is fixedly connected inside the housing 1 and located on the outer surface of the power block 8. The exhaust end of the heat dissipation mechanism 10 is positioned directly opposite the cooling mechanism 11. The cooling mechanism 11 includes a liquid tank 111 fixedly connected inside the housing 1. The liquid tank 111 is filled with perfluoroketone liquid (it should be noted that the perfluoroketone liquid may be designated as Novec 649 or Novec). 1230; As an electric fire extinguishing agent: its dielectric strength is very high, even higher than that of air, making it an excellent insulator. It can be directly sprayed onto burning, energized electrical equipment without causing short circuits or electric shock risks. It completely evaporates after extinguishing the fire, leaving no residue and will not damage expensive electronic equipment. It is non-toxic to humans at normal concentrations. It extinguishes fires primarily through heat absorption and cooling, and physical isolation of oxygen, rather than through chemical reactions, making it very safe. As a refrigerant: these liquids have a high latent heat of vaporization, meaning they can absorb a large amount of heat. This is the core principle of the refrigeration cycle. In high-end computing, heat-generating electronic components are directly immersed in a tank containing perfluoroketone. The liquid absorbs heat and partially vaporizes, then cools down and turns the gas back into a liquid, forming a highly efficient closed-loop cooling system. This cooling method is far more efficient than traditional air cooling and water cooling. A liquid filling pipe is fixedly connected to the liquid tank 111. The liquid filling pipe is used to add perfluoroketone liquid to the liquid tank 111. The exhaust pipe 101 is fixed. The exhaust end of the suction pipe 101, connected to the liquid tank 111, is positioned directly opposite the vent 112 and communicates with the interior of the vent 112. The vent 112 is fixedly connected inside the liquid tank 111. A pump body 113 is fixedly connected to the liquid tank 111. A heat exchange pipe 114 is fixedly connected to the discharge end of the pump body 113. The heat exchange pipe 114 is located on the outer surface of the power supply block 8. A spray pipe 117 is fixedly connected to the portion of the heat exchange pipe 114 below the power supply block 8. An overflow valve (the overflow valve is...) is installed inside the spray pipe 117. The prior art, not shown in the figure, will not be described in detail. In addition, it should be noted that when the pump body 113 is working, within 10 seconds after the heat exchange tube 114 is blocked, the internal pressure of the heat exchange tube 114 will be greater than the opening pressure of the overflow valve, thereby causing the overflow valve to open. The spray pipe 117 has a spray hole 118. The heat exchange tube 114 is fixedly connected to the box 1 by the fixed pipe bracket 115. The end of the heat exchange tube 114 is fixedly connected to the return pipe 116, and the return pipe 116 is fixedly connected to the liquid tank 111.

[0026] During charging and discharging, the pump body 113 is activated, causing it to draw perfluoroketone from the liquid tank 111 into the heat exchange tube 114, and then return it to the liquid tank 111 through the return pipe 116. Since the heat exchange tube 114 is located around the power block 8, the perfluoroketone flowing through the heat exchange tube 114 will dissipate heat from the power block 8, thus reducing the impact of temperature on the charging and discharging process of the power block 8. During this process, the air entering the exhaust pipe 101 will enter the vent 112 and then be discharged through the top of the vent 112, allowing the outside air to dissipate heat from the perfluoroketone liquid in the liquid tank 111 after absorbing heat from the power block 8, further improving the heat dissipation efficiency of the power block 8, thereby further improving the charging and discharging efficiency of the energy storage power supply.

[0027] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, an inspection mechanism 12 is fixedly connected inside the housing 1. The inspection mechanism 12 includes an upper inspection section 121, a middle inspection section 122, and a lower inspection section 123 fixedly connected inside the housing 1. The upper inspection section 121 is located above the top power block 8, the middle inspection section 122 is located between the two power blocks 8, and the lower inspection section 123 is located below the bottom power block 8. A fixing frame 124 and a connecting plate 125 are fixedly connected inside the housing 1. The upper inspection section 121 includes an upper fixing plate 1210 fixedly connected inside the housing 1. One side of the upper fixing plate 1210 is fixed... An upper inspection rope 1211 is fixedly connected to the housing 1. The upper inspection rope 1211 slides through the fixed frame 124. An upper guide rope plate 1212 is fixedly connected inside the housing 1. An upper guide cylinder 1213 is fixedly connected to the upper guide rope plate 1212. The upper inspection rope 1211 passes through the upper guide rope plate 1212 and is slidably connected to the upper guide cylinder 1213. An upper push frame 1214 is fixedly connected to the end of the upper inspection rope 1211. An upper push spring 1215 is fixedly connected to the upper push frame 1214. An upper roller 1216 is rotatably connected to the end of the upper push frame 1214. The upper push spring 1215 is fixedly connected to the connecting plate 125. The middle inspection section 122 includes a middle fixing plate 1220 fixedly connected to the housing 1. A middle inspection rope 1221 is fixedly connected to the middle fixing plate 1220. The middle inspection rope 1221 is slidably connected to the fixing frame 124. A middle push frame 1222 is fixedly connected to the end of the middle inspection rope 1221. A middle push spring 1223 is fixedly connected to one end of the middle push frame 1222. The middle push spring 1223 is fixedly connected to the fixing frame 124. A middle roller 1224 is rotatably connected to the other end of the middle push spring 1223. The lower inspection section 123 includes a lower fixing plate 1220 fixedly connected to the housing 1. A fixed plate 1230 is provided. A lower inspection rope 1231 is fixedly connected to the lower fixed plate 1230. A lower guide rope plate 1232 is fixedly connected inside the housing 1. A lower guide cylinder 1233 is fixedly connected to the lower guide rope plate 1232. The lower inspection rope 1231 passes through the lower guide rope plate 1232 and is slidably connected to the lower guide cylinder 1233. A lower push frame 1234 is fixedly connected to the end of the lower inspection rope 1231. A lower roller 1236 is fixedly connected to the end of the lower push frame 1234. A lower push spring 1235 is fixedly connected to the lower push frame 1234. The lower push spring 1235 is fixedly connected to the connecting plate 125.

[0028] When in use, if a fire occurs at the bottom or right side of the power block 8 or the circuit board 6, the fire will burn through the lower inspection rope 1231. At this time, the lower pusher 1234 will move upward under the action of the lower push spring 1235. When a fire occurs at the top of the lower power block 8 or the bottom of the upper power block 8, the fire will burn through the middle inspection rope 1221. At this time, the middle push frame 1222 will move to the right under the action of the middle push spring 1223. When a fire occurs on the top or right side of the power block 8 located above, the fire will burn through the upper inspection rope 1211. At this time, the upper push frame 1214 will move downward under the action of the upper push spring 1215. It can detect whether the power block 8 is on fire in a timely manner, ensuring the timely protection of the energy storage power supply in the event of a fire, and guaranteeing the safety of the energy storage power supply.

[0029] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, a switching mechanism 13 is fixedly connected inside the housing 1. The switching mechanism 13 is driven by the inspection mechanism 12. When one of the upper inspection section 121, the middle inspection section 122, and the lower inspection section 123 breaks, the inspection mechanism 12 drives the switching mechanism 13 to block the cooling mechanism 11. When the upper inspection section 121, the middle inspection section 122, and the lower inspection section 123 are simultaneously tightened, the inspection mechanism 12 drives the switching mechanism 13 to open the cooling mechanism 11. The switching mechanism 13 includes multiple telescopic rods 132 fixedly connected inside the housing 1. A push plate 131 is fixedly connected to the end of each telescopic rod 132. A connecting spring 133 is sleeved on the telescopic rod 132 located in the middle. An upper push spring 1215, a middle push spring 1223, and a lower push spring 1215 are also included. The elastic force of 35 is greater than that of the connecting spring 133. The two ends of the connecting spring 133 are fixedly connected to the push plate 131 and the housing 1 respectively. A push block 134 is fixedly connected to one side of the push plate 131. Three push grooves 135 are opened on the push block 134. The three push grooves 135 are all inclined. The three push grooves 135 are respectively adapted to the upper push frame 1214, the middle push frame 1222 and the lower push frame 1234. A sealing plate 136 is fixedly connected to one side of the push plate 131 located on the push block 134. A sealing chamber 137 is fixedly connected to one side of the heat exchange tube 114. The sealing plate 136 and the sealing chamber 137 are slidably connected. The upper inspection rope 1211, the middle inspection rope 1221 and the lower inspection rope 1231 are all made of a material that is easily burned.

[0030] When the test rope 1231 breaks during use, the lower pusher 1234 will move upward under the action of the lower pusher spring 1235. At this time, the lower pusher 1234 will push the pusher block 134 towards the direction of the box cover 2 through the lower roller 1236 and the pusher groove 135 located below, thereby pulling the pusher plate 131 towards the direction of the box cover 2, so that the sealing plate 136 enters the heat exchange tube 114 and blocks the heat exchange tube 114, so that the pressure in the part of the heat exchange tube 114 that is blocked to the discharge end of the pump body 113 increases. When the pressure is greater than the opening pressure of the overflow valve in the spray pipe 117, the overflow valve opens, so that the spray hole 118 sprays the perfluoroketone liquid into the power block 8 and the box body 1. When the inspection rope 1221 breaks, the middle pusher 1222 will move to the right under the action of the middle pusher spring 1223. At this time, the middle pusher 1222 will push the pusher block 134 to move towards the direction of the box cover 2 through the middle roller 1224 and the pusher groove 135 located in the middle, thereby pulling the pusher plate 131 to move towards the direction of the box cover 2, so that the sealing plate 136 enters the heat exchange tube 114 and blocks the heat exchange tube 114, so that the pressure in the part of the heat exchange tube 114 that is blocked to the discharge end of the pump body 113 increases. When the pressure is greater than the opening pressure of the overflow valve in the spray pipe 117, the overflow valve opens, so that the spray hole 118 sprays the perfluoroketone liquid into the power block 8 and the box body 1. When the upper inspection rope 1211 breaks, the upper push frame 1214 will move downward under the action of the upper push spring 1215. At this time, the upper push frame 1214 will push the push block 134 towards the direction of the box cover 2 through the upper roller 1216 and the push groove 135 located above, thereby pulling the push plate 131 towards the direction of the box cover 2, so that the sealing plate 136 enters the heat exchange tube 114 and blocks the heat exchange tube 114, so that the pressure in the part of the heat exchange tube 114 that is blocked to the discharge end of the pump body 113 increases. When the pressure is greater than the opening pressure of the overflow valve in the spray pipe 117, the overflow valve opens, so that the spray hole 118 sprays the perfluoroketone liquid into the power block 8 and the box body 1. The perfluoroketone liquid is atomized inside the housing 1 through the nozzle 118. In addition, when a fire occurs inside the energy storage power supply, the energy storage power supply is in working state, that is, the exhaust pipe 101 is in the exhaust state, which will cause the gas inside the housing 1 to circulate, thereby filling the housing 1 with the atomized perfluoroketone liquid. After the fire has been burning for a period of time, the motor 105 is turned off, and the housing 1 will be filled with perfluoroketone liquid, realizing the fire extinguishing operation of the power block 8, improving the timeliness of fire extinguishing, and achieving good protection for the energy storage power supply. In addition, when the energy storage power supply is repaired after a fire, the upper inspection rope 1211, middle inspection rope 1221 and lower inspection rope 1231 are all tightened, so that the upper push frame 1214, middle push frame 1222 and lower push frame 1234 cannot push the push block 134 to move. Only then will the push block 134 drive the sealing plate 136 to be pulled away from the heat exchange tube 114 under the action of the connecting spring 133. This ensures that the energy storage power supply can be extinguished in time no matter which part of the power block 8 catches fire, thus ensuring the safety of the energy storage power supply during operation.

[0031] The specific working principle of this invention is as follows: During charging, the charging device is connected to the power grid through the socket 7, and the power block 8 can be charged through the circuit board 6. During discharging, the energy storage power is connected to the electrical device through the socket 7, and the discharge power is adjusted through the touch screen 3. During the charging and discharging process, the touch screen 3 always displays the charging and discharging power, so that the user can clearly understand the charging and discharging power. During the charging and discharging process, the starting motor 105 causes the rotating shaft 106 to drive the fan blades 107 to rotate, which in turn causes the air extraction pipe 101 to draw in the outside air filtered by the filter screen 102 and enter the air extraction pipe 101, and then discharge it into the housing 1 through the air outlet 103. Then the outside air will flow upward through the power block 8 and finally be discharged to the outside through the louver 5. This achieves the cooling operation of the power block 8, the circuit board 6 and the touch screen 3, and avoids the high temperature of the power block 8, which would limit the current during the charging and discharging process of the energy storage power supply, thereby improving the charging and discharging power of the energy storage power supply. At the same time, the pump body 113 is started, which draws the perfluoroketone in the liquid tank 111 into the heat exchange tube 114 and returns it to the liquid tank 111 through the return pipe 116. Since the heat exchange tube 114 is located around the power block 8, the perfluoroketone will dissipate heat from the power block 8 when it flows in the heat exchange tube 114, thereby reducing the temperature of the power block 8 and reducing the impact of temperature on the charging and discharging process of the power block 8. In addition, during this process, the air entering the exhaust pipe 101 will enter the ventilation channel 112 and then be discharged through the top of the ventilation channel 112, so that the outside air dissipates the perfluoroketone liquid in the liquid tank 111 after absorbing the heat of the power block 8, further improving the heat dissipation efficiency of the power block 8, thereby further improving the charging and discharging efficiency of the energy storage power supply. Furthermore, during the charging and discharging process, if a fire occurs at the bottom or right side of the power block 8 or the circuit board 6, the fire will burn through the lower inspection rope 1231. At this time, the lower pusher 1234 will move upward under the action of the lower push spring 1235. The lower pusher 1234 will push the push block 134 towards the direction of the box cover 2 through the lower roller 1236 and the push groove 135 located below, thereby pulling the push plate 131 towards the direction of the box cover 2, so that the sealing plate 136 enters the heat exchange tube 114 and seals the heat exchange tube 114, so that the pressure in the part of the heat exchange tube 114 that is sealed to the discharge end of the pump body 113 increases. When the pressure is greater than the opening pressure of the overflow valve in the spray pipe 117, the overflow valve opens, so that the spray hole 118 sprays the perfluoroketone liquid into the power block 8 and the box body 1. When a fire occurs at the top of the lower power block 8 or the bottom of the upper power block 8, the fire will burn through the middle inspection rope 1221. At this time, the middle pusher 1222 will move to the right under the action of the middle push spring 1223. The middle pusher 1222 will push the pusher block 134 towards the direction of the box cover 2 through the middle roller 1224 and the push groove 135 in the middle. This will pull the push plate 131 towards the direction of the box cover 2, so that the sealing plate 136 enters the heat exchange tube 114 and seals the heat exchange tube 114. This will increase the pressure in the part of the heat exchange tube 114 that is sealed to the discharge end of the pump body 113. When the pressure is greater than the opening pressure of the overflow valve in the spray pipe 117, the overflow valve opens, so that the spray hole 118 sprays the perfluoroketone liquid into the power block 8 and the box body 1. When a fire occurs on the top or right side of the power block 8 located above, the fire will burn through the upper inspection rope 1211. At this time, the upper pusher 1214 will move downward under the action of the upper push spring 1215. The upper pusher 1214 will push the pusher block 134 towards the direction of the box cover 2 through the upper roller 1216 and the upper push groove 135, thereby pulling the push plate 131 towards the direction of the box cover 2, so that the sealing plate 136 enters the heat exchange tube 114 and seals the heat exchange tube 114, so that the pressure in the part of the heat exchange tube 114 that is sealed to the discharge end of the pump body 113 increases. When the pressure is greater than the opening pressure of the overflow valve in the spray pipe 117, the overflow valve opens, so that the spray hole 118 sprays the perfluoroketone liquid into the power block 8 and the box body 1. The perfluoroketone liquid is atomized inside the housing 1 through the nozzle 118. In addition, when a fire occurs inside the energy storage power supply, the energy storage power supply is in working state, that is, the exhaust pipe 101 is in the exhaust state, which will cause the gas inside the housing 1 to circulate, thereby filling the housing 1 with the atomized perfluoroketone liquid. After the fire has been burning for a period of time, the motor 105 is turned off, and the housing 1 will be filled with perfluoroketone liquid, realizing the fire extinguishing operation of the power block 8, improving the timeliness of fire extinguishing, and achieving good protection for the energy storage power supply. In addition, when the energy storage power supply is repaired after a fire, the upper inspection rope 1211, middle inspection rope 1221 and lower inspection rope 1231 are all tightened, so that the upper push frame 1214, middle push frame 1222 and lower push frame 1234 cannot push the push block 134 to move. Only then will the push block 134 drive the sealing plate 136 to be pulled away from the heat exchange tube 114 under the action of the connecting spring 133. This ensures that the energy storage power supply can be extinguished in time no matter which part of the power block 8 catches fire, thus ensuring the safety of the energy storage power supply during operation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
