[0018] Example 1

[0019] See also Figure 1-12 A substation with heat dissipation function includes a base 1 and a controller. The substation is controlled by the controller. A substation box 2 is fixed on the top of the base 1, and a cabinet door is provided on the front of the substation box 2. A top frame 21 is fixed at the edge of the top of the substation box 2. Exhaust grooves 22 are fixed on both sides of the top of the substation box 2. A plurality of outer grooves 24 are symmetrically provided on the outer walls on both sides of the substation box 2. Inner grooves 25 are provided on both sides of the top and bottom of the outer grooves 24. A spring 26 is fixed inside the inner groove 25. A ventilation filter 27 is fixed at one end of the spring 26, and the ventilation filter 27 is clamped inside the outer groove 24. A motor 3 is fixed to the inner wall of the substation box 2, and a first blade shaft 31 is fixed to the outside of the output shaft of the motor 3. A closing component is provided on the top of the top frame 21, and the closing component is used to close the exhaust slot 22. A water cooling component is provided on the closing component, and the water cooling component is used to enhance the heat dissipation of the substation box 2. The closing component includes a closing plate 4, and the closing plate 4 is clamped on the top of the top frame 21. A water inlet cavity 401 is provided inside the top of the closing plate 4. A cylinder 41 is fixed to the top of the substation box 2, and the output shaft of the cylinder 41 is slidably connected to the closing plate 4. A top cover 42 is fixed to the output shaft of the cylinder 41, and the top cover 42 is located inside the water inlet cavity 401. A raindrop sensor 421 is fixed to the top of the top cover 42; Limiting tubes 23 are fixed on both sides of the top of the transformer substation box 2, rubber plugs 43 are fixed on both sides of the bottom of the closing plate 4, and the limiting tubes 23 are slidably sealed and connected with the rubber plugs 43, and sealing boxes 44 are fixed on both sides of the top plate of the inner cavity of the transformer substation box 2, the sealing box 44 is communicated with the limiting tubes 23, and the rubber plug 43 is slidably sealed and connected with the sealing box 44, and a top rod 45 is slidably sealed inside the sealing box 44, and a connecting plate 46 is fixed on one end of the top rod 45 close to the ventilation filter 27, and connecting arms 48 are fixed on both sides of the connecting plate 46 close to one end of the ventilation filter 27, and the connecting arms 48 are fixed to the ventilation filter 27, and a scraper 47 is fixed on one side of the connecting plate 46 close to the ventilation filter 27, and an inner groove 241 is provided on one side of the outer groove 24, and the scraper 47 is slidably connected with the inner groove 241; During the specific operation, when the weather is clear, the cylinder 41 is started by the controller, so that the cylinder 41 drives the top cover 42 to be lifted up inside the water inlet chamber 401 until the two ends of the top cover 42 abut against the two ends of the top of the water inlet chamber 401, so that the top cover 42 drives the closing plate 4 to be lifted up synchronously, and then the closing plate 4 is disengaged from the top frame 21, so that the top of the top frame 21 is in an open state, and at the same time, as the closing plate 4 is disengaged from the top frame 21, the closing plate 4 is completely disengaged from the exhaust slot 22, that is, the top of the exhaust slot 22 loses the shielding of the closing plate 4, thereby allowing the inner cavity of the substation box 2 to complete air convection with the outside through the exhaust slot 22; Since the hot air generated in the transformer substation box 2 is heavier than the air at room temperature, that is, the hot air is lighter than the air at room temperature, the hot air can rise after being generated and be directly discharged to the outside through the exhaust slot 22, thereby improving the natural heat dissipation effect inside the transformer substation box 2; At the same time, during the lifting process of the closing plate 4, the closing plate 4 drives the rubber plug 43 to be lifted synchronously, so that the closing plate 4 drives the rubber plug 43 to slide inside the limiting tube 23, so that the space inside the limiting tube 23 and the sealing box 44 is increased, and the air pressure is reduced. Under the action of the tension of the spring 26, the spring 26 drives the ventilation filter 27 to be connected to the inside of the outer groove 24. As the ventilation filter 27 is connected to the inside of the outer groove 24, the ventilation filter 27 drives the connecting arm 48 and the scraper 47 to slide inside the inner groove 241, so that the scraper 47 and the inner groove 241 are in an open state, and then the outer groove 24 is connected to the inside of the substation box 2, thereby allowing the hot air inside the substation box 2 to be transmitted to the outside through the outer groove 24, and then having the effect of heat dissipation of the substation box 2; When the exhaust groove 22 and the outer groove 24 are both connected to the inside of the substation box 2, the motor 3 is started by the controller, so that the motor 3 drives the first fan shaft 31 to rotate inside the substation box 2, thereby accelerating the speed of air circulation in the substation box 2, further increasing the heat dissipation effect; On the contrary, on rainy days, raindrops are sensed by the raindrop sensor 421. When the rainfall is heavy, the raindrop sensor 421 can transmit a signal to the controller, and the controller can control the cylinder 41 to reset, so that the cylinder 41 drives the top cover 42 to reset. Under the influence of gravity, the closing plate 4 is mounted on the top of the top cover 42 and resets synchronously, and the closing plate 4 covers the top frame 21 and the exhaust slot 22, so that rainwater cannot enter the interior of the substation box 2 through the exhaust slot 22. At the same time, during the resetting process, the closing plate 4 drives the rubber plug 43 to reset, so that the rubber plug 43 slides inside the limiting tube 23 and the sealing box 44, so that the space inside the limiting tube 23 and the sealing box 44 is reduced, the air pressure is increased, and then the push rod 45 is pushed out inside the sealing box 44, so that the push rod 45 drives the connecting plate 46 to be pushed out toward the direction of the outer groove 24, so that the connecting plate 46 drives the connecting arm 48 to move toward the direction of the ventilation filter 27, and then the ventilation filter 27 is separated from the inside of the outer groove 24 to the outside of the transformer substation box 2. At the same time, the connecting plate 46 drives the scraper 47 to be completely engaged with the inside of the inner groove 241, so that the inner groove 241 is closed, and then rainwater cannot enter the inside of the transformer substation box 2 through the outer groove 24, thereby avoiding rainwater from entering the inside of the transformer substation box 2, and improving the safety of the electrical equipment inside the transformer substation box 2; Furthermore, when the scraper 47 moves inside the inner groove 241, the scraper 47 cleans the inner wall of the inner groove 241, so that the dust accumulated inside the inner groove 241 is swept out of the outside of the outer groove 24. At the same time, when the scraper 47 is fully engaged into the inner groove 241, the ventilation filter 27 is fully exposed to the outside of the substation box 2, that is, the ventilation filter 27 is fully exposed to the rainwater. At this time, the ventilation filter 27 can be flushed by rainwater, so that the blocked filter holes in the ventilation filter 27 can be cleaned and unblocked, thereby ensuring that after the ventilation filter 27 is re-engaged into the outer groove 24, the smoothness of the air circulation inside and outside the substation box 2 can be improved, and the heat dissipation effect of the substation box 2 is further improved.

[0020] It should be noted that the reference Figure 3 The top of the exhaust slot 22 is inclined, and a filter hole is also provided on one side of the exhaust slot 22, and filter holes are also provided on both sides of the top frame 21 below the closing plate 4. As a result, when the closing plate 4 is closed and shielded to the top frame 21, the hot air in the substation box 2 can still be discharged to the outside through the exhaust slot 22 and the filter holes provided on one side of the top frame 21 for heat dissipation. At the same time, the filter holes on one side of the top frame 21 are completely covered by the closing plate 4, and there is no need to worry about rainwater entering the top of the substation box 2 through the top frame 21.

[0021] Example 2

[0022] The water cooling component includes a water delivery channel 5, which is opened inside the closing plate 4 on a side away from the cabinet door. A water delivery pipe 51 is fixed to the side of the top of the substation box 2 close to the water delivery channel 5. The water inlet cavity 401, the water delivery channel 5 and the water delivery pipe 51 are connected to each other. A water pump 52 is fixed to the side of the top of the substation box 2 close to the water delivery pipe 51, and the water outlet pipe of the water pump 52 is connected to the water delivery pipe 51. A cooling pipe 53 is fixed to the bottom of the water delivery pipe 51. A plurality of heat sinks 54 are fixedly connected to the surface of the cooling pipe 53, and one side of the heat sink 54 is located inside the cooling pipe 53. One end of the cooling pipe 53 is fixed to the water inlet pipe of the water pump 52. The second blade shaft 32 is rotatably connected to the inner wall of the transformer substation box 2 near the cabinet door, and the second blade shaft 32 is transmission-connected to the first blade shaft 31 through a belt 33. One end of the second blade shaft 32 and the first blade shaft 31 are both sealed and rotatably connected to the cooling pipe 53. The second blade shaft 32 and the first blade shaft 31 are fixed with a linkage arc plate 34 at one end located in the cooling pipe 53. A three-way pipe 6 is fixed to the bottom of the cooling pipe 53. The two ends of the bottom of the three-way pipe 6 pass through the two sides of the transformer substation box 2. A storage groove 11 is provided inside the base 1. A protective frame 12 is slidably connected inside the storage groove 11. A drainage groove 13 is provided on the inner wall of the storage groove 11, and a one-way valve is provided in the drainage groove 13. The two ends of the bottom of the three-way pipe 6 pass through the tops of the two sides of the protective frame 12 respectively, and are located inside the storage groove 11. Specifically, on the basis of the first embodiment, when the cylinder 41 is completely reset, the top of the exhaust groove 22 and the inner groove 241 are in a completely closed state, and the top of the water inlet chamber 401 is in an open state. At this time, rainwater can be accumulated in the water inlet chamber 401, and enter the water delivery channel 5 through the water inlet chamber 401, and then enter the water delivery pipe 51 through the water delivery channel 5, so that the rainwater enters the cooling pipe 53 through the water delivery pipe 51, and then the water pump 52 is started by the controller, so that the water pump 52 absorbs and pumps water to the cooling pipe 53, and then the rainwater circulates in the cooling pipe 53; When rainwater flows inside the cooling pipe 53, it passes through the heat sink 54 and cools the heat sink 54, taking away the heat adsorbed on the equipment in the substation box 2 by the surface of the heat sink 54, and then plays the effect of using rainwater to water-cool the electrical equipment in the substation box 2, so that the outer tank 24 is in a completely closed state, further improving the heat dissipation effect of the substation box 2; Furthermore, when rainwater circulates inside the cooling tube 53, it will impact the linkage arc plate 34, causing the linkage arc plate 34 to rotate inside the cooling tube 53, and then drive the first blade shaft 31 and the second blade shaft 32 to rotate through the linkage arc plate 34. At this time, the motor 3 stops powering the first blade shaft 31, so that the first blade shaft 31 and the second blade shaft 32 rotate without power consumption, thereby enhancing the heat dissipation of the substation box 2, and cooperates with the water cooling of rainwater to further enhance the heat dissipation effect of the substation box 2; Furthermore, when the temperature of the rainwater in the cooling pipe 53 is not enough for effective heat dissipation, or when the rainfall is heavy and there is waterlogging, the one-way valve of the three-way pipe 6 can be opened to allow the rainwater in the cooling pipe 53 to be discharged into the storage tank 11 through the three-way pipe 6. When the rainwater accumulates in the storage tank 11, it is affected by buoyancy, so that the rainwater lifts the protective frame 12, so that the protective frame 12 floats out of the storage tank 11 and closes the cabinet door gap of the substation box 2 until the protective frame 12 is limited by the two ends of the three-way pipe 6 and cannot continue to be pushed out. At this time, the cabinet door of the substation box 2 is protected by the protective frame 12, so that the minimum height of the cabinet door gap of the substation box 2 is increased, thereby avoiding the ground water level from being too high, reducing the possibility of ground water entering the inside of the substation box 2 through the cabinet door gap of the substation box 2, and thus improving the protection effect of the substation box 2; At the same time, as rainwater is injected into the storage groove 11, the weight of the base 1 increases. Since the base 1 and the transformer substation box 2 are fixedly connected, the weight of the transformer substation box 2 is indirectly increased, making the transformer substation box 2 more stable, ensuring the stability of the transformer substation box 2 during waterlogging, and preventing the transformer substation box 2 from being washed away by rainwater caused by waterlogging, thereby protecting the transformer substation box 2. When it rains or the waterlogging ends, the rainwater in the storage groove 11 can be discharged through the drainage groove 13, and then the protective frame 12 is reset, so that the cabinet door of the transformer substation box 2 is unshielded.

[0023] It should be noted that the second blade shaft 32 is connected to the first blade shaft 31 through a belt 33, that is, in the first embodiment, when the motor 3 is started, the motor 3 drives the first blade shaft 31 to rotate, and the first blade shaft 31 drives the second blade shaft 32 to rotate synchronously through the belt 33, thereby making the first blade shaft 31 and the second blade shaft 32 rotate synchronously inside the substation box 2, further improving the heat dissipation effect of the substation box 2; A one-way valve is provided inside the end of the water pipe 51 connected to the water channel 5, so that the water pipe 51 can control the replacement of rainwater in the cooling pipe 53, so that after the rainwater in the cooling pipe 53 reaches a certain temperature, the rainwater with lower temperature is transported to the cooling pipe 53 through the water pipe 51, and a one-way valve is also provided inside the three-way pipe 6, so that when the cooling pipe 53 needs to replace rainwater or fill water into the storage tank 11, the one-way valve inside the three-way pipe 6 can be used to connect the three-way pipe 6 and the cooling pipe 53.

[0024] Example 3

[0025] Stands 7 are fixed on both sides of the top of the closing plate 4, and snow-clearing plates 71 are rotatably connected on both sides of the stand 7. The bottom ends of the snow-clearing plates 71 are inclined. The surfaces of the two ends of the closing plate 4 are rotatably connected with movable plates 72, and the two movable plates 72 are respectively located at the tops of the two ends of the closing plate 4, and the ends of the movable plates 72 close to the snow-clearing plates 71 are inclined. During the specific operation, when it is snowing, since the top cover 42 and the movable plate 72 are completely exposed to the air, snow will accumulate on the top of the movable plate 72 and the top cover 42. At this time, the cylinder 41 is controlled by the controller to be repeatedly started and reset, and the cylinder 41 drives the top cover 42 to be repeatedly ejected and reset. During this process, the top cover 42 repeatedly contacts the top of the water inlet chamber 401 and vibrates, thereby gradually shaking off the snow on the top of the top cover 42 and falling into the inside of the water inlet chamber 401. When the snow melts, it can be used as a cooling liquid, and according to the operation of the second embodiment, the heat dissipation operation is performed on the inside of the substation box 2, further improving the heat dissipation effect of the substation box 2; Furthermore, after the snow on the top of the top cover 42 is shaken off, the top cover 42 and the water inlet chamber 401 are kept in a state of repeated contact, so that the closing plate 4 drives the movable plate 72 to vibrate repeatedly, thereby loosening the snow on the top of the movable plate 72. At the same time, the repeated contact between the top cover 42 and the closing plate 4 also plays a role of vibrating the snow-clearing plate 71, so that the snow-clearing plate 71 gradually thaws the frozen state. When the top cover 42 is completely restored, the snow-clearing plate 71 that has been thawed is restored under the action of gravity, and the snow-clearing plate 71 is perpendicular to the bottom of the water inlet chamber 401. Then, the movable plate 72 loses the limiting support of the snow-clearing plate 71, so that the movable plate 72, under the action of gravity, flips back and falls against the surface of the closing plate 4. In the process of flipping and falling of the movable plate 72, the movable plate 72 also vibrates, which can loosen the snow on the top of the movable plate 72. Subsequently, when the top cover 42 is pushed out again, it can contact the snow-clearing plate 71, so that the top cover 42 drives the snow-clearing plate 71 to gradually flip toward the direction of the movable plate 72, until the snow-clearing plate 71 contacts the movable plate 72, driving the movable plate 72 to flip, and then the movable plate 72 drives the snow on the top to flip, that is, during the repeated lifting and resetting process of the top cover 42, the movable plate 72 is in a state of repeated flipping and falling vibration, and then the snow on the top of the movable plate 72 gradually loosens and slides off, thereby allowing the present invention to perform snow-clearing operations on the movable plate 72 and the top cover 42 on snowy days, thereby avoiding excessive load on the substation box 2, which may cause damage and malfunction, and at the same time avoiding the blocking of the raindrop sensor 421 by the accumulated snow, thereby ensuring the accuracy of the raindrop sensing by the raindrop sensor 421 in the later stage.
