Description

Technical Field

[0001] This invention relates to the field of energy storage and power distribution technology, specifically to an energy storage and power distribution device and a power distribution testing system. Background Technology

[0002] Before using energy storage and distribution equipment, it needs to be tested by corresponding power distribution testing equipment. When existing energy storage and distribution equipment and power distribution testing systems are in use, the energy storage and distribution terminals generate a lot of heat. Most devices use air blowing to cool the energy storage and distribution terminals. This method fails to filter and recover large particulate impurities in the extracted gas, and also fails to filter out water vapor in the gas. This results in poor dust protection for the energy storage and distribution terminals. In addition, the water vapor in the gas blowing directly onto the energy storage and distribution equipment can cause safety hazards. Furthermore, when the energy storage and distribution equipment malfunctions and produces smoke due to the malfunction, the device fails to recover and treat large particulate impurities and toxic impurities in the smoke.

[0013] Beneficial effects

[0014] This invention provides an energy storage power distribution device and a power distribution testing system. Compared with the prior art, it has the following advantages:

[0015] (1) The energy storage power distribution equipment and power distribution test system, by setting up a gear ring assembly and a water pump assembly in the device, during the process of the air pump drawing in external gas and cooling the energy storage battery, the motor drives the filter cylinder and cooling ring to rotate through the pulley assembly and gear ring assembly. The air inlet filter in the rotating filter cylinder filters out large particulate impurities in the drawn gas, while the scraper scrapes the surface of the air inlet filter. At the same time, the water pump assembly draws in external cold water and injects it into the cooling tank in the cooling ring. When the cold water flows through the cooling ring, it absorbs heat and cools the gas through heat exchange. The water vapor in the gas liquefies when it encounters cold and remains on the lower side of the casing. This setting filters and cools the impurities in the drawn gas before blowing and cooling the energy storage battery, which plays a role in dust prevention and avoids the water vapor in the drawn gas from directly blowing on the energy storage battery, causing safety hazards, and also avoids the high temperature of the drawn gas from affecting heat dissipation.

[0016] (2) The energy storage and power distribution equipment and power distribution testing system, by setting a feeding component in the device, after the scraper in the housing cleans the impurities attached to the surface of the air intake filter in the filter cartridge, the impurities on the surface of the air intake filter fall off and fall onto the baffle. The micro cylinder is activated and the micro cylinder drives the baffle to retract. The impurities on the baffle fall into the recycling box through the feeding shell. The anti-blocking wheel rotates under the action of the gear to avoid the feeding shell from being blocked. This setting makes it convenient for users to collect the impurities that fall off the filter end in a timely manner and avoid excessive accumulation of impurities that fall off the filter end.

[0017] (3) The energy storage power distribution equipment and power distribution test system, by setting up a recovery component and two three-way valves in the device, when the smoke sensor in the housing detects smoke, the first three-way valve and the second three-way valve switch, and the solenoid valve starts. At this time, the air pump draws gas and smoke from the housing through the housing, the first three-way valve, the switching pipe, the solenoid valve, and the ventilation plate. When the gas and smoke pass through the housing, the filter cartridge filters the large particulate impurities in the smoke, and the cooling ring absorbs the heat in the smoke. The gas drawn by the air pump is injected into the treatment liquid in the storage tank through the branch pipe, the stirring rod, and the slot. The treatment liquid absorbs the toxic impurities in the gas. The motor drives the stirring rod to stir the treatment liquid through the pulley assembly and the bevel gear assembly, which promotes the full contact between the treatment liquid and the toxic impurities in the gas. When the energy storage battery fails and smokes, this device can filter the solid impurities in the smoke in time and recover the toxic impurities in the smoke, reducing dust pollution and safety hazards.

[0028] The exhaust end of the air pump 4 is equipped with a second three-way valve 8. The right side of the second three-way valve 8 is equipped with a conduit 9. The top of the housing 1 is equipped with a vent plate 10 that is fixedly connected to and communicates with the conduit 9. The lower side of the housing 5 is equipped with a bracket that is fixedly connected to the housing 1. The upper left side of the bracket is equipped with a motor 11. The output end of the motor 11 is connected to a pulley assembly 12. The lower left side of the housing 5 is equipped with a feeding part 13. The upper side of the pulley assembly 12 is connected to a gear ring assembly 14. The left side of the housing 5 is rotatably connected to a filter cartridge 15 that is connected to the gear ring assembly 14. The left side of the housing 5 near the filter cartridge 15 is equipped with a scraper 16. The bottom of the vent plate 10 is equipped with several vent holes that communicate with the conduit 9.

The left side of the filter cartridge 15 is equipped with an air inlet filter that is in contact with the scraper 16.

[0029] A cooling ring 17 is rotatably connected to the right side of the housing 5 and fixedly connected to the right side of the filter cartridge 15. A sealing gasket is provided on the outside of the cooling ring 17. The water pump assembly 7 consists of a water pump, a water suction pipe, and an injection pipe. The water pump is fixedly connected to the outside of the housing 5. The water pump suction end is fixedly connected to the water suction pipe. The water pump discharge end is fixedly connected to the injection pipe. The injection pipe is fixedly connected to the housing 5. A water passage groove communicating with the injection pipe is provided on the inside of the housing 5 near the cooling ring 17. A water passage ring communicating with the water passage groove is provided on the outside of the cooling ring 17. A drain pipe communicating with the water passage ring is provided at the bottom of the housing 5. A recycling component 18 is connected to the lower right end of the pulley assembly 12.

[0030] During the charging and discharging process of the energy storage battery 2, the air pump 4 draws in external gas and blows it to cool the energy storage battery 2. The motor 11 drives the filter cartridge 15 and cooling ring 17 to rotate via the pulley assembly 12 and gear ring assembly 14. The rotating filter cartridge 15's air intake filter filters large particles of impurities in the drawn gas, while the scraper 16 scrapes the surface of the air intake filter to promote the removal of impurities. Simultaneously, the water pump assembly 7 draws in external cold water, which then flows through a water channel and water ring into the cooling tank within the cooling ring 17. Finally, the water is discharged to a water source through a drain channel and drain pipe. As the cold water flows through the cooling ring 17, it absorbs heat and cools the passing gas through heat exchange. The water vapor in the gas liquefies upon cooling and remains on the lower side of the casing 5. The energy storage battery 2 is electrically connected to the power distribution test piece 3 via a switch, and is also electrically connected to the power switch (a selector switch) and an external load.

[0031] like Figure 1-5 The second embodiment shown differs from the first embodiment mainly in that:

[0032] The feeding component 13 consists of a miniature cylinder 131, a stop block 132, a feeding shell 133, an anti-blocking wheel 134, and a recycling box 135. The fixed end of the miniature cylinder 131 is fixedly connected to the housing 5. The stop block 132 is slidably connected to the lower left side of the housing 5 near the filter cartridge 15. The lower end of the housing 5 near the stop block 132 is fixedly connected to the feeding shell 133. The stop block 132 is fixedly connected to the extended end of the miniature cylinder 131. The anti-blocking wheel 134 is rotatably connected to the inner end of the feeding shell 133 and is coaxial with the gear inside the gear ring assembly 14. The bracket is fixedly connected to the bottom of the discharge shell 133 and slidably connected to the recycling box 135; after the scraper 16 inside the housing 5 cleans the impurities attached to the surface of the air intake filter screen inside the filter cartridge 15, the impurities on the surface of the air intake filter screen fall off and fall onto the baffle 132. The micro cylinder 131 is activated, and the micro cylinder 131 drives the baffle 132 to retract. The impurities on the baffle 132 fall into the recycling box 135 through the discharge shell 133. The anti-blocking wheel 134 rotates under the action of the gear to prevent the discharge shell 133 from being blocked.

[0033] like Figure 1-6 The main difference between the second embodiment shown and the second embodiment is that:

[0034] The recycling component 18 consists of a bevel gear assembly 181, a liquid storage tank 182, a stirring rod 183, and a branch pipe 184. The left-side driving bevel gear of the bevel gear assembly 181 is coaxially and fixedly connected to the right-side driving belt pulley in the pulley assembly 12. The liquid storage tank 182 is fixedly connected to the bracket and its inner end is filled with processing liquid. The branch pipe 184 is fixedly connected to the right side of the second three-way valve 8 and the top of the liquid storage tank 182, respectively. The stirring rod 183 is rotatably connected to the middle part of the liquid storage tank 182. The bottom of the branch pipe 184 is rotatably connected to the upper end of the stirring rod 183 and communicates with it. The bottom of the stirring rod 183 is provided with a slot for connecting to the branch pipe 184. The driven bevel gear in the bevel gear assembly 181 is coaxially and fixedly connected to the stirring rod 183. A pressure relief valve is provided on the top right side of the liquid storage tank 182. A second valve is provided on the upper left side of the liquid storage tank 182. A third valve is provided on the lower left side of the liquid storage tank 182. An inlet pipe is provided on the left side of the second valve. A discharge pipe is provided on the left side of the third valve.

[0035] When the smoke sensor detects smoke inside the housing 1, it stops supplying power to the energy storage battery 2 and closes the internal switch of the power distribution test piece 3. The first three-way valve 6 and the second three-way valve 8 are reversed, and the solenoid valve is started. At this time, the air pump 4 extracts gas and smoke from the housing 1 through the housing 5, the first three-way valve 6, the reversing pipe 19, the solenoid valve, and the ventilation plate 10. When the gas and smoke pass through the housing 5, the filter cartridge 15 filters large particulate impurities in the smoke, and the cooling ring 17 absorbs heat from the smoke. Finally, the gas extracted by the air pump 4 is injected into the treatment liquid in the liquid storage tank 182 through the branch pipe 184, the stirring rod 183, and the slot. The treatment liquid absorbs toxic impurities in the gas. The motor 11 drives the stirring rod 183 to stir the treatment liquid through the pulley assembly 12 and the bevel gear assembly 181, promoting full contact between the treatment liquid and the toxic impurities in the gas.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During use, the user charges the energy storage battery 2 through an external power source. After charging is complete, the user turns on the switch inside the power distribution test piece 3. The energy storage battery 2 supplies power to the power distribution test piece 3. The detection instrument inside the power distribution test piece 3 tests the power supplied by the energy storage battery 2. This is existing technology, so its specific operating principle will not be described in detail. During the charging and discharging process of the energy storage battery 2, the air pump 4, water pump assembly 7, and motor 11 are started. The air pump 4 draws air from the outside through the housing 5 and the first three-way valve 6. Then, the gas is injected into the housing 1 through the second three-way valve 8, the conduit 9, and the vent plate 10 to blow and dissipate heat from the energy storage battery 2. After the heat dissipation is complete, the gas is discharged through the exhaust filter.

[0038] The motor 11 drives the filter cartridge 15 and cooling ring 17 to rotate via the pulley assembly 12 and gear ring assembly 14. The air intake filter in the rotating filter cartridge 15 filters large particulate impurities in the drawn gas, while the scraper 16 scrapes the surface of the air intake filter to promote the removal of impurities. At the same time, the water pump assembly 7 draws in external cold water, which then flows through the water channel and water ring into the cooling tank in the cooling ring 17. Finally, the water is discharged to the water source through the drain channel and drain pipe. When the cold water flows through the cooling ring 17, it absorbs heat and cools the gas through heat exchange. The water vapor in the gas liquefies upon cooling and remains on the lower side of the casing 5. The first valve is opened periodically to discharge the retained liquid.
