Technical Field

[0001] The invention relates to the technical field of transformer substations, in particular to a box-type transformer substation with heat dissipation and dust prevention functions. Background Art

[0002] Box-type substation is a kind of indoor and outdoor compact power distribution equipment prefabricated in a factory, which is equipped with high-voltage switchgear, distribution transformer and low-voltage distribution device according to a certain wiring scheme. It combines transformer step-down and low-voltage distribution functions organically and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substation. Box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of power distribution equipment.

[0003] Existing box-type substations usually use heat dissipation holes for heat dissipation and ventilation. The heat dissipation efficiency is low when the heat dissipation holes are used for free ventilation. In the process of heat dissipation, some dust will enter the shell through the heat dissipation holes, and the dust will adhere to the electrical components, thereby affecting the normal operation of the electrical components. Summary of the invention

[0004] The object of the present invention is to provide a box-type substation with heat dissipation and dust prevention functions to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A box-type substation with heat dissipation and dustproof function, comprising: a box, an energy storage device is arranged on the top of the box, a heat dissipation device is arranged in the box, one end of the water storage tank is connected to the energy storage device, and the other end of the water storage tank is connected to the heat dissipation device; the energy storage device comprises: a solar panel, the solar panel is arranged on the top of the box, the heat dissipation device is used to dissipate heat for the box, and a temperature sensor is arranged in the box;

[0007] When the temperature in the box rises, the controller controls the heat dissipation device to start, and the heat dissipation device immediately dissipates heat inside the box, thereby ensuring that the temperature in the box is within a normal range and ensuring the normal operation of the electrical components in the box.

[0008] Preferably, a water storage tank is provided on the top of the box body, a plurality of infusion tubes are provided on the side of the box body, and the plurality of infusion tubes are equally arranged along the side of the box body, an inclined surface is provided in the water storage tank, the inclined surface is inclined toward the side close to the infusion tube, the infusion tube extends toward the side close to the water tank, one end of the infusion tube is connected to the water storage tank, and the other end of the infusion tube is connected to the water tank, a water delivery tube is provided on the side of the water tank away from the infusion tube, the water delivery tube is connected to an external water source, and a water level sensor is provided in the water tank;

[0009] When it is a rainy day, rainwater falls on the solar panels, and then flows into the water tank through the gap between two adjacent solar panels. Since the water tank is provided with an inclined surface, and the inclined surface is inclined toward the side close to the infusion pipe, the rainwater moves through the water tank to the infusion pipe, and then the rainwater is transported to the water tank through the infusion pipe. The water level sensor in the water tank continuously converts the water level signal into an electrical signal and transmits it to the controller, which analyzes it. If the water level in the water tank does not reach the amount of water stored in the water tank, the controller controls the water pipe to open, and the external water source is then transported to the water tank through the water pipe for storage.

[0010] Preferably, the number of the solar panels is several, and the several solar panels are equally arranged on the top of the box body, a power cavity is provided between the box body and the water storage tank, a battery is provided in the power cavity, the solar panels are connected to the battery through a circuit, and the battery is connected to the heat dissipation device through a circuit;

[0011] When it is a sunny day, the solar panels convert solar energy into electrical energy and transmit it to the battery for storage. When a power outage occurs, the battery transmits the stored electrical energy to the heat sink through the circuit, thereby ensuring the normal operation of the heat sink and avoiding the problem of the heat sink being unable to work due to a power outage.

[0012] Preferably, the heat dissipation device includes: a heat dissipation port, the number of the heat dissipation ports is several, the heat dissipation port is arranged between two adjacent infusion tubes, a slide groove is arranged on the side wall of the infusion tube, a rack is arranged in the slide groove, a gear is arranged in the slide groove, a dust removal plate is arranged on the side of the gear close to the heat dissipation port, a micro motor is arranged on the side of the dust removal plate close to the infusion tube, the driving shaft of the micro motor is connected to the gear, and the gear is meshed with the rack for transmission.

[0013] Preferably, a water inlet pipe is provided on the side of the heat dissipation port close to the water tank, the water inlet pipe extends close to the water tank, one end of the water inlet pipe is connected to the water tank, a micro pump is provided in the water inlet pipe, one end of the micro pump is connected to the water tank through a pipeline, and the other end of the micro pump is connected to the double-headed pipe through a pipeline.

[0014] Preferably, a double-ended pipe is provided in the heat dissipation port, the double-ended pipe is connected to the water inlet pipe, the micro pump is connected to the double-ended pipe through a pipeline, a rotating blade ring is provided on the side of the double-ended pipe close to the dust removal plate, a No. 1 electromagnetic coil is provided in the heat dissipation port, the outer ring of the rotating blade ring is a magnetic conductor, and the rotating blade ring is rotatably connected to the heat dissipation port and the double-ended pipe respectively.

[0015] Preferably, an atomizer is provided in the double-headed tube, a bell mouth is provided on the side of the double-headed tube close to the rotating blade ring, a plurality of nozzles are provided on the side of the double-headed tube close to the inside of the box, the plurality of nozzles are arranged around the axis of the heat dissipation port, and a guide cone is provided on the side of the nozzle close to the double-headed tube.

[0016] Preferably, the diameter Dv0.50 of the droplets sprayed from the nozzle is less than 200 μm, and the diameter Dv0.99 of the droplets sprayed from the nozzle is less than 400 μm;

[0017] When the temperature in the box is in a normal state, the dust removal plate is located on the side of the heat dissipation port away from the inside of the box, that is, the dust removal plate blocks the heat dissipation port, and at the same time, the controller controls the No. 1 electromagnetic coil to be positively energized. After the No. 1 electromagnetic coil is energized, it generates magnetic force. Since the outer ring of the rotating blade ring is a magnetic conductor, the rotating blade ring immediately rotates in the positive direction, and the rotating blade ring immediately transports air to the inside of the box, and transports the outside air to the inside of the box through the heat dissipation port, thereby ensuring the circulation of air flow inside the box, so that the temperature in the box is maintained within the normal temperature range, and the outside air extracted by the rotating blade ring encounters the dust removal plate before entering the heat dissipation port. The dust removal plate absorbs and blocks the dust in the outside air, preventing the dust from entering the box, thereby interfering with the normal operation of the electrical components, thereby improving the dust-proof effect of the box;

[0018] The temperature sensor in the box converts the heat signal in the box into an electrical signal in real time and transmits it to the controller. The controller then analyzes the electrical signal. When the temperature in the box exceeds the maximum value set by the temperature sensor, the controller controls the micro pump in the water inlet pipe to start. The micro pump extracts water from the water inlet pipe and transports it to the double-headed pipe after pressurization, so that the water is transported to the double-headed pipe through the water inlet pipe. When the water enters the double-headed pipe, the water passes through the atomizer in the double-headed pipe to form water mist. At this time, the controller controls the bell mouth to open, and the water mist is immediately sprayed out through the bell mouth. The sprayed water mist passes through the dust removal plate, so that the water mist cleans the dust removal plate and cleans the dust adsorbed on the surface of the dust removal plate, thereby reducing the workload of the staff for cleaning the dust removal plate and improving the cleanliness of the dust removal plate, thereby improving the dust prevention effect of the box.

[0019] When the water mist is sprayed out from the bell mouth, the high-pressure water mist is discharged through the heat dissipation port, thereby driving the airflow of the heat dissipation port. The airflow flows at a high speed from the heat dissipation port to the side close to the dust removal plate, so that the gas in the box also flows along with it, and then the water mist is sprayed out from the heat dissipation port to the outside of the box, so that the hot air in the box also flows along with it, and the hot air is then discharged through the heat dissipation port, thereby realizing the heat dissipation in the box, thereby reducing the temperature in the box and ensuring the normal operation of the electrical components in the box; at the same time, after the water mist is sprayed to the outside of the box, the heat generated by the sun will evaporate the droplets of the water mist, and evaporation is an endothermic phenomenon, thereby reducing the external ambient temperature of the box, further dissipating the heat and cooling the box, thereby improving the efficiency of heat dissipation and cooling of the box;

[0020] When a fire occurs in the box, after the temperature sensor in the box detects that the temperature rises abnormally, the controller first controls the micro motor in the dust removal plate to start, and the driving shaft in the micro motor drives the gear to rotate. When the gear rotates, it meshes with the rack in the slide slot, and then the gear moves along the slide slot. When the gear moves, it drives the dust removal plate to move to the side close to the solar panel, so that the dust removal plate is separated from the heat dissipation port, and then the controller opens the nozzle. Since the nozzle is arranged around the axis of the double-headed pipe, the water mist moves from the double-headed pipe to the nozzle. When the water mist is sprayed from the nozzle, it is in a blooming state, thereby increasing the diffusion area of ​​the water mist, and since the diameter of the droplets sprayed from the nozzle Dv0.50 is less than 200μm, and the diameter of the droplets sprayed from the nozzle Dv0.99 is less than 400μm, and through the restriction of the nozzle, the fine water mist sprayed from the nozzle has good electrical insulation. When it is directly sprayed to the charged high-voltage electrode, the leakage current is very small, and no flashover phenomenon will occur. Therefore, during the fire extinguishing process, no leakage phenomenon will occur, thereby improving the safety of fire extinguishing of electrical components;

[0021] The fine water mist sprayed from the nozzle not only extinguishes the fire source, but also cools down the inside of the box, so that the temperature inside the box is reduced. At the same time, the controller controls the No. 1 electromagnetic coil to pass a reverse current, and the No. 1 electromagnetic coil drives the rotating blade ring to reverse, thereby causing the rotating blade ring to generate a reverse airflow. The fine water mist sprayed from the nozzle will also drive the airflow outside the box to flow, so that the airflow outside the box will move to the side close to the heat dissipation port, so that the reverse airflow generated by the rotating blade ring and the airflow outside the box form a relative movement, so that the reverse airflow generated by the rotating blade ring blocks the airflow outside the box, and thus the airflow outside the box cannot enter the box, so that the combustion-supporting agent in the box is reduced, which further improves the fire extinguishing efficiency in the box, and the reverse airflow generated by the rotating blade ring will also drive a part of the fine water mist to be transported to the outside of the box, so that the fine water mist will also reduce the temperature of the external environment of the box.

[0022] Preferably, an internal circulation device is also provided in the box body, and the internal circulation device includes: an air intake pipe, the air intake pipe is symmetrically arranged on the side of the box body, the air intake pipe extends to the side close to the water tank, a plurality of No. 1 cooling pipes are provided in the water tank, a connecting pipe is provided between two adjacent No. 1 cooling pipes, one end of the No. 1 cooling pipe is connected to the air intake pipe, and the other end of the No. 1 cooling pipe is connected to the connecting pipe, and a fan is provided on the side of the air intake pipe close to the box body.

[0023] Preferably, an air outlet pipe is provided between two adjacent air inlet pipes, one end of the air outlet pipe extends toward the top of the box body, and the other end of the air outlet pipe extends toward the water storage tank, a No. 2 cooling pipe is provided at one end of the air outlet pipe close to the water storage tank, one end of the No. 2 cooling pipe is connected to the air outlet pipe, and the other end of the No. 1 cooling pipe is connected to the connecting pipe; a cooling pipe is provided at one end of the air outlet pipe close to the top of the box body, and the cooling pipe is provided in the box body, and both the No. 1 cooling pipe and the No. 2 cooling pipe are corrugated pipes;

[0024] When the environment is humid, the controller controls the fan in the air intake pipe to start, and the fan extracts the hot air in the box, and the hot air then enters the air intake pipe through the box, and then the hot air is transported to the No. 1 cooling pipe through the air intake pipe. Since the No. 1 cooling pipe is arranged in the water storage tank and is a corrugated pipe, the contact area between the No. 1 cooling pipe and the water in the water storage tank is increased, so that the hot air in the No. 1 cooling pipe is fully heat-exchanged with the water in the water storage tank to form cold air, and then the cold air that has been cooled once is transported from the No. 1 cooling pipe to the connecting pipe, and the cold air is transported to the side close to the No. 2 cooling pipe through the connecting pipe, and then The No. 2 cooling pipe is also arranged in the water storage tank and is also a corrugated pipe. The cold air is further cooled and cooled in the No. 2 cooling pipe, so that the residual heat in the cold air is diffused out through the No. 2 cooling pipe. The gas cooled twice is then transported to the outlet pipe through the No. 2 cooling pipe, and finally transported to the cooling pipe through the outlet pipe, and sprayed into the box from the cooling pipe, thereby realizing heat dissipation and cooling of the substation in a humid and humid environment, achieving the effect of internal circulation heat dissipation of the box, avoiding the entry of moisture-carrying air from the outside into the box, thereby avoiding damage to the electrical components in the box by moisture from the outside.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0026] 1. By conveying water to the double-headed pipe, the double-headed pipe atomizes the water into water mist. The high-pressure water mist can not only drive the hot air in the box to be transported outward through the heat dissipation port when the temperature of the box is high, but also clean the dust on the dust removal plate, reducing the workload of the staff for cleaning the dust removal plate and improving the cleanliness of the dust removal plate, thereby improving the dust-proof effect of the box; and when a fire occurs in the box, the water mist forms fine water mist through the nozzle, and the box is extinguished and cooled under the condition of ensuring that there is no safety problem caused by leakage, thereby improving the efficiency of fire extinguishing in the box and reducing the damage to the electrical components in the box caused by the fire.

[0027] 2. When the environment is humid, the controller controls the fan in the air intake pipe to start, and the fan extracts the hot air in the box, and the hot air then enters the air intake pipe through the box, and then the hot air is transported to the No. 1 cooling pipe through the air intake pipe. Since the No. 1 cooling pipe is set in the water storage tank and is a corrugated pipe, the contact area between the No. 1 cooling pipe and the water in the water storage tank is increased, so that the hot air in the No. 1 cooling pipe can fully exchange heat with the water in the water storage tank to form cold air. Then, the cold air that has been cooled once is transported from the No. 1 cooling pipe to the connecting pipe, and the cold air is transported to the side close to the No. 2 cooling pipe through the connecting pipe. Since the No. 2 cooling pipe is also arranged in the water storage tank and is also a corrugated pipe, the cold air is further cooled and cooled in the No. 2 cooling pipe, so that the residual heat in the cold air is diffused out through the No. 2 cooling pipe. The gas cooled twice is then transported to the outlet pipe through the No. 2 cooling pipe, and finally transported to the cooling pipe through the outlet pipe, and sprayed into the box from the cooling pipe, thereby realizing heat dissipation and cooling of the substation in a humid and humid environment, achieving the effect of internal circulation heat dissipation of the box, avoiding the entry of moisture-carrying air from the outside into the box, thereby avoiding damage to the electrical components in the box by moisture from the outside.

[0046] When the temperature in the box 1 rises, the controller controls the heat dissipation device 4 to start, and the heat dissipation device 4 then dissipates heat inside the box 1, thereby ensuring that the temperature in the box 1 is within a normal range and ensuring the normal operation of the electrical components in the box 1.

[0047] As a specific embodiment of the present invention, a water storage tank 11 is provided on the top of the box body 1, and a plurality of infusion tubes 12 are provided on the side of the box body 1, and the plurality of infusion tubes 12 are equally arranged along the side of the box body 1, and an inclined surface is provided in the water storage tank 11, and the inclined surface is inclined toward the side close to the infusion tube 12, and the infusion tube 12 extends toward the side close to the water tank 3, and one end of the infusion tube 12 is connected to the water storage tank 11, and the other end of the infusion tube 12 is connected to the water tank 3, and a water delivery tube 31 is provided on the side of the water tank 3 away from the infusion tube 12, and the water delivery tube 31 is connected to an external water source, and a water level sensor is provided in the water tank 3;

[0048] When it is a rainy day, rainwater falls on the solar panel 21, and then flows into the water tank 11 through the gap between two adjacent solar panels 21. Since the water tank 11 is provided with an inclined surface, and the inclined surface is inclined toward the side close to the infusion pipe 12, the rainwater moves through the water tank 11 to the infusion pipe 12, and then the rainwater is transported to the water tank 3 through the infusion pipe 12. The water level sensor in the water tank 3 continuously converts the water level signal into an electrical signal and transmits it to the controller, which analyzes it. If the water level in the water tank 3 does not reach the amount of water stored in the water tank 3, the controller controls the water pipe 31 to open, and the external water source is then transported to the water tank 3 through the water pipe 31 for storage.

[0049] As a specific embodiment of the present invention, the number of the solar panels 21 is several, and the several solar panels 21 are equally arranged on the top of the box body 1, a power cavity 22 is provided between the box body 1 and the water storage tank 3, a battery 23 is provided in the power cavity 22, the solar panels 21 are connected to the battery 23 through a circuit, and the battery 23 is connected to the heat dissipation device 4 through a circuit;

[0050] When the environment is sunny, the solar panel 21 converts solar energy into electrical energy and transmits it to the battery 23 for storage. When a power outage occurs, the battery 23 transmits the stored electrical energy to the heat dissipation device 4 through the circuit.

[0051] As a specific embodiment of the present invention, the heat dissipation device 4 includes: a heat dissipation port 41, the number of the heat dissipation ports 41 is several, the heat dissipation port 41 is arranged between two adjacent infusion tubes 12, a slide groove 13 is arranged on the side wall of the infusion tube 12, a rack is arranged in the slide groove 13, a gear is arranged in the slide groove 13, a dust removal plate 42 is arranged on the side of the gear close to the heat dissipation port 41, a micro motor is arranged on the side of the dust removal plate 42 close to the infusion tube 12, the driving shaft of the micro motor is connected to the gear, and the gear is meshed with the rack for transmission.

[0052] As a specific embodiment of the present invention, a water inlet pipe 43 is arranged on the side of the heat dissipation port 41 close to the water tank 3, and the water inlet pipe 43 extends toward the water tank 3. One end of the water inlet pipe 43 is connected to the water tank 3. A micro pump is arranged in the water inlet pipe 43, and one end of the micro pump is connected to the water tank 3 through a pipeline, and the other end of the micro pump is connected to the double-headed pipe 45 through a pipeline.

[0053] As a specific embodiment of the present invention, a double-headed pipe 45 is provided in the heat dissipation port 41, and the double-headed pipe 45 is connected to the water inlet pipe 43. The micro pump is connected to the double-headed pipe 45 through a pipeline. A rotating blade ring 46 is provided on the side of the double-headed pipe 45 close to the dust removal plate 42. A No. 1 electromagnetic coil is provided in the heat dissipation port 41, and the outer ring of the rotating blade ring 46 is a magnetic conductor. The rotating blade ring 46 is rotatably connected to the heat dissipation port 41 and the double-headed pipe 45 respectively.

[0054] As a specific embodiment of the present invention, an atomizer is provided in the double-headed tube 45, a bell mouth 47 is provided on the side of the double-headed tube 45 close to the rotating blade ring 46, a plurality of nozzles 48 are provided on the side of the double-headed tube 45 close to the inside of the box body 1, and the plurality of nozzles 48 are arranged around the axis of the heat dissipation port 41, and a guide cone is provided on the side of the nozzle 48 close to the double-headed tube 45.

[0055] As a specific embodiment of the present invention, the diameter Dv0.50 of the droplets sprayed from the nozzle 48 is less than 200 μm, and the diameter Dv0.99 of the droplets sprayed from the nozzle 48 is less than 400 μm;

[0056] When the temperature in the box body 1 is in a normal state, the dust removal plate 42 is located on the side of the heat dissipation port 41 away from the inside of the box body 1, that is, the dust removal plate 42 blocks the heat dissipation port 41, and at the same time, the controller controls the No. 1 electromagnetic coil to be positively energized. After the No. 1 electromagnetic coil is energized, a magnetic force is generated. Since the outer ring of the rotating leaf ring 46 is a magnetic conductor, the rotating leaf ring 46 immediately rotates in the positive direction, and the rotating leaf ring 46 immediately conveys airflow to the inside of the box body 1, and conveys the outside air to the inside of the box body 1 through the heat dissipation port 41, thereby ensuring the circulation of airflow inside the box body 1, so that the temperature in the box body 1 is maintained within the normal temperature range, and the outside air extracted by the rotating leaf ring 46 encounters the dust removal plate 42 before entering the heat dissipation port 41, and the dust removal plate 42 adsorbs and blocks the dust in the outside air;

[0057] The temperature sensor in the box body 1 converts the heat signal in the box body 1 into an electrical signal in real time, and transmits it to the controller, which then analyzes the electrical signal. When the temperature in the box body 1 exceeds the maximum value set by the temperature sensor, during the water transportation process, the controller controls the micro pump in the water inlet pipe 43 to start, and the micro pump extracts the water in the water inlet pipe 43, and transports it to the double-headed pipe 45 after pressurization, so that the water is transported to the double-headed pipe 45 through the water inlet pipe 43. After the water enters the double-headed pipe 45, the water passes through the atomizer in the double-headed pipe 45 to form water mist. At this time, the controller controls the bell mouth 47 to open, and the water mist is immediately sprayed outward through the bell mouth 47. The sprayed water mist passes through the dust removal plate 42, so that the water mist cleans the dust removal plate 42 and cleans the dust adsorbed on the surface of the dust removal plate 42.

[0058] When the water mist is sprayed out from the bell mouth 47, the high-pressure water mist is discharged through the heat dissipation port 41, thereby driving the airflow of the heat dissipation port 41, and the airflow flows at a high speed from the heat dissipation port 41 to the side close to the dust removal plate 42, so that the gas in the box body 1 also flows along with it, and then the water mist is sprayed out from the heat dissipation port 41 to the outside of the box body 1, so that the hot air in the box body 1 also flows along with it, and the hot air is then discharged through the heat dissipation port 41, thereby achieving heat dissipation in the box body 1; at the same time, after the water mist is sprayed to the outside of the box body 1, the heat generated by the sun will evaporate the droplets of the water mist, and evaporation is an endothermic phenomenon, so that the external environment temperature of the box body 1 is also reduced;

[0059] When a fire occurs in the box 1, after the temperature sensor in the box 1 detects an abnormal increase in temperature, the controller first controls the micro motor in the dust removal plate 42 to start, and the drive shaft in the micro motor drives the gear to rotate. When the gear rotates, it meshes with the rack in the slide slot 13, and then the gear moves along the slide slot 13. When the gear moves, it drives the dust removal plate 42 to move to the side close to the solar panel 21, so that the dust removal plate 42 is separated from the heat dissipation port 41, and then the controller opens the nozzle 48. Since the nozzle 48 is arranged around the axis of the double-headed pipe 45, the water mist is generated by The double-headed pipe 45 moves toward the nozzle 48, and the water mist is in a blooming state when it is sprayed from the nozzle 48, thereby increasing the diffusion area of ​​the water mist. In addition, since the diameter Dv0.50 of the mist droplets sprayed from the nozzle 48 is less than 200 μm, and the diameter Dv0.99 of the mist droplets sprayed from the nozzle 48 is less than 400 μm, and the fine water mist sprayed from the nozzle 48 has good electrical insulation due to the restriction of the nozzle 48, when it is directly sprayed to the charged high-voltage electrode, the leakage current is very small, and no flashover phenomenon occurs, so that no leakage phenomenon occurs during the fire extinguishing process;

[0060] The fine water mist sprayed from the nozzle 48 not only extinguishes the fire source, but also cools down the inside of the box body 1, so that the temperature inside the box body 1 is reduced. At the same time, the controller controls the No. 1 electromagnetic coil to pass a reverse current, and the No. 1 electromagnetic coil drives the rotating leaf ring 46 to reverse, thereby causing the rotating leaf ring 46 to generate a reverse airflow. Since the fine water mist sprayed from the nozzle 48 will also drive the airflow outside the box body 1 to flow, the airflow outside the box body 1 will move to the side close to the heat dissipation port 41, so that the reverse airflow generated by the rotating leaf ring 46 and the airflow outside the box body 1 form a relative movement, so that the reverse airflow generated by the rotating leaf ring 46 blocks the airflow outside the box body 1, and thus the airflow outside the box body 1 cannot enter the box body 1, so that the combustion-supporting agent in the box body 1 is reduced, and the reverse airflow generated by the rotating leaf ring 46 will also drive a part of the fine water mist to be transported to the outside of the box body 1, so that the fine water mist will also reduce the temperature of the external environment of the box body 1.

[0061] As a specific embodiment of the present invention, an internal circulation device 5 is also provided in the box body 1, and the internal circulation device 5 includes: an air intake pipe 51, the air intake pipe 51 is symmetrically arranged on the side of the box body 1, and the air intake pipe 51 extends to the side close to the water storage tank 3, and a plurality of No. 1 cooling pipes 52 are arranged in the water storage tank 3, and a connecting pipe 53 is arranged between two adjacent No. 1 cooling pipes 52, one end of the No. 1 cooling pipe 52 is connected to the air intake pipe 51, and the other end of the No. 1 cooling pipe 52 is connected to the connecting pipe 53, and a fan is arranged on the side of the air intake pipe 51 close to the box body 1.

[0062] As a specific embodiment of the present invention, an air outlet pipe 54 is arranged between two adjacent air inlet pipes 51, one end of the air outlet pipe 54 extends to the top of the box body 1, and the other end of the air outlet pipe 54 extends to the water storage tank 3, and a second cooling pipe 55 is arranged at one end of the air outlet pipe 54 close to the water storage tank 3, one end of the second cooling pipe 55 is connected to the air outlet pipe 54, and the other end of the first cooling pipe 52 is connected to the connecting pipe 53; a cooling pipe 56 is arranged at one end of the air outlet pipe 54 close to the top of the box body 1, and the cooling pipe 56 is arranged in the box body 1, and the first cooling pipe 52 and the second cooling pipe 55 are both corrugated pipes;

[0063] When the environment is humid, the controller controls the fan in the air intake pipe 51 to start, and the fan extracts the hot air in the box body 1, and the hot air then enters the air intake pipe 51 through the box body 1, and then the hot air is transported to the first cooling pipe 52 through the air intake pipe 51. Since the first cooling pipe 52 is arranged in the water storage tank 3 and is a corrugated pipe, the contact area between the first cooling pipe 52 and the water in the water storage tank 3 is increased, so that the hot air in the first cooling pipe 52 is fully heat-exchanged with the water in the water storage tank 3 to form cold air, and then the cold air that has been cooled once is transported from the first cooling pipe 52 to the connecting pipe 53, and the cold air is transported to the side close to the second cooling pipe 55 through the connecting pipe 53. Since the No. 2 cooling pipe 55 is also arranged in the water storage tank 3 and is also a corrugated pipe, the cold air is further cooled and cooled in the No. 2 cooling pipe 55, so that the residual heat in the cold air is diffused out through the No. 2 cooling pipe 55, and the gas cooled twice is then transported to the outlet pipe 54 through the No. 2 cooling pipe 55, and finally transported to the cooling pipe 56 through the outlet pipe 54, and sprayed into the box body 1 from the cooling pipe 56, thereby realizing heat dissipation and cooling of the substation in a moist and humid environment, achieving the effect of internal circulation heat dissipation of the box body 1, avoiding the outside air with moisture from entering the box body 1, thereby avoiding the damage of the external moisture to the electrical components in the box body 1.

[0064] Working principle of the present invention:

[0065] When the temperature in the box 1 rises, the controller controls the heat dissipation device 4 to start, and the heat dissipation device 4 then performs heat dissipation treatment inside the box 1, thereby ensuring that the temperature in the box 1 is within a normal range and ensuring the normal operation of the electrical components in the box 1;

[0066] When it is rainy, rain falls on the solar panel 21, and then flows into the water tank 11 through the gap between two adjacent solar panels 21. Since the water tank 11 is provided with an inclined surface, and the inclined surface is inclined toward the side close to the infusion pipe 12, the rain moves through the water tank 11 to the infusion pipe 12, and then the rain is transported to the water tank 3 through the infusion pipe 12. The water level sensor in the water tank 3 continuously converts the water level signal into an electrical signal and transmits it to the controller, which analyzes it. If the water level in the water tank 3 does not reach the amount of water stored in the water tank 3, the controller controls the water pipe 31 to open, and the external water source is then transported to the water tank 3 through the water pipe 31 for storage;

[0067] When the environment is sunny, the solar panel 21 converts solar energy into electrical energy and transmits it to the battery 23 for storage. When a power outage occurs, the battery 23 transmits the stored electrical energy to the heat dissipation device 4 through the circuit.

[0068] When the temperature in the box body 1 is in a normal state, the dust removal plate 42 is located on the side of the heat dissipation port 41 away from the inside of the box body 1, that is, the dust removal plate 42 blocks the heat dissipation port 41, and at the same time, the controller controls the No. 1 electromagnetic coil to be positively energized. After the No. 1 electromagnetic coil is energized, a magnetic force is generated. Since the outer ring of the rotating leaf ring 46 is a magnetic conductor, the rotating leaf ring 46 immediately rotates in the positive direction, and the rotating leaf ring 46 immediately conveys airflow to the inside of the box body 1, and conveys the outside air to the inside of the box body 1 through the heat dissipation port 41, thereby ensuring the circulation of airflow inside the box body 1, so that the temperature in the box body 1 is maintained within the normal temperature range, and the outside air extracted by the rotating leaf ring 46 encounters the dust removal plate 42 before entering the heat dissipation port 41, and the dust removal plate 42 adsorbs and blocks the dust in the outside air;

[0069] The temperature sensor in the box body 1 converts the heat signal in the box body 1 into an electrical signal in real time, and transmits it to the controller, which then analyzes the electrical signal. When the temperature in the box body 1 exceeds the maximum value set by the temperature sensor, during the water transportation process, the controller controls the micro pump in the water inlet pipe 43 to start, and the micro pump extracts the water in the water inlet pipe 43, and transports it to the double-headed pipe 45 after pressurization, so that the water is transported to the double-headed pipe 45 through the water inlet pipe 43. After the water enters the double-headed pipe 45, the water passes through the atomizer in the double-headed pipe 45 to form water mist. At this time, the controller controls the bell mouth 47 to open, and the water mist is immediately sprayed outward through the bell mouth 47. The sprayed water mist passes through the dust removal plate 42, so that the water mist cleans the dust removal plate 42 and cleans the dust adsorbed on the surface of the dust removal plate 42.

[0070] When the water mist is sprayed out from the bell mouth 47, the high-pressure water mist is discharged through the heat dissipation port 41, thereby driving the airflow of the heat dissipation port 41, and the airflow flows at a high speed from the heat dissipation port 41 to the side close to the dust removal plate 42, so that the gas in the box body 1 also flows along with it, and then the water mist is sprayed out from the heat dissipation port 41 to the outside of the box body 1, so that the hot air in the box body 1 also flows along with it, and the hot air is then discharged through the heat dissipation port 41, thereby achieving heat dissipation in the box body 1; at the same time, after the water mist is sprayed to the outside of the box body 1, the heat generated by the sun will evaporate the droplets of the water mist, and evaporation is an endothermic phenomenon, so that the external environment temperature of the box body 1 is also reduced;

[0071] When a fire occurs in the box 1, after the temperature sensor in the box 1 detects an abnormal increase in temperature, the controller first controls the micro motor in the dust removal plate 42 to start, and the drive shaft in the micro motor drives the gear to rotate. When the gear rotates, it meshes with the rack in the slide slot 13, and then the gear moves along the slide slot 13. When the gear moves, it drives the dust removal plate 42 to move to the side close to the solar panel 21, so that the dust removal plate 42 is separated from the heat dissipation port 41, and then the controller opens the nozzle 48. Since the nozzle 48 is arranged around the axis of the double-headed pipe 45, the water mist is generated by The double-headed pipe 45 moves toward the nozzle 48, and the water mist is in a blooming state when it is sprayed from the nozzle 48, thereby increasing the diffusion area of ​​the water mist. In addition, since the diameter Dv0.50 of the mist droplets sprayed from the nozzle 48 is less than 200 μm, and the diameter Dv0.99 of the mist droplets sprayed from the nozzle 48 is less than 400 μm, and the fine water mist sprayed from the nozzle 48 has good electrical insulation due to the restriction of the nozzle 48, when it is directly sprayed to the charged high-voltage electrode, the leakage current is very small, and no flashover phenomenon occurs, so that no leakage phenomenon occurs during the fire extinguishing process;

[0072] The fine water mist sprayed from the nozzle 48 not only extinguishes the fire source, but also cools down the inside of the box body 1, so that the temperature inside the box body 1 is reduced. At the same time, the controller controls the No. 1 electromagnetic coil to pass reverse current, and the No. 1 electromagnetic coil drives the rotating leaf ring 46 to reverse, thereby causing the rotating leaf ring 46 to generate a reverse airflow. Since the fine water mist sprayed from the nozzle 48 will also drive the airflow outside the box body 1 to flow, the airflow outside the box body 1 will move to the side close to the heat dissipation port 41, so that the reverse airflow generated by the rotating leaf ring 46 and the airflow outside the box body 1 form a relative movement, so that the reverse airflow generated by the rotating leaf ring 46 blocks the airflow outside the box body 1, and thus the airflow outside the box body 1 cannot enter the box body 1, so that the combustion-supporting agent in the box body 1 is reduced, and the reverse airflow generated by the rotating leaf ring 46 will also drive a part of the fine water mist to be transported to the outside of the box body 1, so that the fine water mist will also reduce the temperature of the external environment of the box body 1;

[0073] When the environment is humid, the controller controls the fan in the air intake pipe 51 to start, and the fan extracts the hot air in the box body 1, and the hot air then enters the air intake pipe 51 through the box body 1, and then the hot air is transported to the first cooling pipe 52 through the air intake pipe 51. Since the first cooling pipe 52 is arranged in the water storage tank 3 and is a corrugated pipe, the contact area between the first cooling pipe 52 and the water in the water storage tank 3 is increased, so that the hot air in the first cooling pipe 52 is fully heat-exchanged with the water in the water storage tank 3 to form cold air, and then the cold air that has been cooled once is transported from the first cooling pipe 52 to the connecting pipe 53, and the cold air is transported to the side close to the second cooling pipe 55 through the connecting pipe 53. Since the No. 2 cooling pipe 55 is also arranged in the water storage tank 3 and is also a corrugated pipe, the cold air is further cooled and cooled in the No. 2 cooling pipe 55, so that the residual heat in the cold air is diffused out through the No. 2 cooling pipe 55, and the gas cooled twice is then transported to the outlet pipe 54 through the No. 2 cooling pipe 55, and finally transported to the cooling pipe 56 through the outlet pipe 54, and sprayed into the box body 1 through the cooling pipe 56, thereby realizing heat dissipation and cooling of the substation in a humid and humid environment, achieving the effect of internal circulation heat dissipation of the box body 1, avoiding the outside air with moisture from entering the box body 1, thereby avoiding the damage of the electrical components in the box body 1 by the outside moisture.
