[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figures 1-12 , a substation with a heat dissipation function, including a base 1 and a controller. The substation is controlled by the controller. A substation box body 2 is fixed on the top of the base 1, and a cabinet door is opened on the front of the substation box body 2. A top frame 21 is fixed at the edge of the top of the substation box body 2, and exhaust grooves 22 are fixed on both sides of the top of the substation box body 2. A plurality of outer grooves 24 are symmetrically opened on the outer walls on both sides of the substation box body 2. Embedded grooves 25 are opened on both sides of the top and bottom of the outer groove 24. A spring 26 is fixed inside the embedded groove 25. One end of the spring 26 is fixed with a ventilation filter 27, and the ventilation filter 27 is clamped inside the outer groove 24;

[0036] The inner wall of the substation box body 2 is fixed with a motor 3. The outside of the output shaft of the motor 3 is fixed with a first fan blade shaft 31. A closing component is arranged on the top of the top frame 21. The closing component is used to close the exhaust groove 22. A water cooling component is arranged on the closing component. The water cooling component is used to enhance the heat dissipation of the substation box body 2. The closing component includes a closing plate 4. The closing plate 4 is clamped on the top of the top frame 21. An inlet water cavity 401 is opened inside the top end of the closing plate 4. A cylinder 41 is fixed on the top of the substation box body 2. The output shaft of the cylinder 41 is slidably connected with the closing plate 4. The output shaft of the cylinder 41 is fixed with a top cover 42, and the top cover 42 is located inside the inlet water cavity 401. A rain drop sensor 421 is fixed on the top of the top cover 42;

[0037] On both sides of the top of the substation box body 2, limiting tubes 23 are fixed. On both sides of the bottom of the closing plate 4, rubber plugs 43 are fixed. The limiting tubes 23 are slidably and sealingly connected with the rubber plugs 43. On both sides of the inner cavity top plate of the substation box body 2, sealing boxes 44 are fixed. The sealing boxes 44 are communicated with the limiting tubes 23, and the rubber plugs 43 are slidably and sealingly connected with the sealing boxes 44. A top rod 45 is slidably and sealingly arranged inside the sealing box 44. One end of the top rod 45 close to the ventilation filter screen 27 is fixed with a connecting plate 46. On both sides of one end of the connecting plate 46 close to the ventilation filter screen 27, connecting arms 48 are fixed. The connecting arms 48 are fixed with the ventilation filter screen 27. On one side of the connecting plate 46 close to the ventilation filter screen 27, a scraping plate 47 is fixed. An inner groove 241 is opened on one side of the outer groove 24, and the scraping plate 47 is slidably connected with the inner groove 241;

[0038] During the specific operation process, when the weather is clear, the cylinder 41 is started through the controller, so that the cylinder 41 drives the top cover 42 to jack up inside the inlet water cavity 401 until both ends of the top cover 42 abut against both ends of the top of the inlet water cavity 401, so that the top cover 42 drives the closing plate 4 to jack up synchronously, and then the closing plate 4 is disengaged from the clamping connection with the top frame 21, so that the top of the top frame 21 is in an open state. At the same time, as the closing plate 4 is disengaged from the top frame 21, the closing plate 4 is disengaged from the exhaust groove 22, that is, the top of the exhaust groove 22 loses the shielding of the closing plate 4, so that the inner cavity of the substation box body 2 can complete the air convection with the outside through the exhaust groove 22;

[0039] Since the hot air generated inside the substation box body 2 is heavier than the normal temperature gas, that is, the hot air is lighter than the normal temperature air, after the hot air is generated, it can rise and be directly discharged to the outside through the exhaust groove 22, thereby improving the natural heat dissipation effect inside the substation box body 2;

[0040] Meanwhile, during the process of the closing plate 4 being lifted, the closing plate 4 drives the rubber plug 43 to be lifted synchronously, causing the closing plate 4 to drive the rubber plug 43 to slide inside the limiting tube 23, increasing the space inside the limiting tube 23 and the sealing box 44, reducing the air pressure. And under the action of the pulling force of the spring 26, the spring 26 drives the ventilation filter screen 27 to be clamped inside the outer groove 24. As the ventilation filter screen 27 is clamped inside the outer groove 24, the ventilation filter screen 27 drives the connecting arm 48 and the scraping plate 47 to slide inside the inner groove 241, causing the scraping plate 47 to be in an open state with the inner groove 241, and then making the outer groove 24 communicate with the inside of the substation box body 2. Thus, the hot air inside the substation box body 2 can be transferred externally through the outer groove 24, and then the effect of dissipating heat from the substation box body 2 is achieved;

[0041] When both the exhaust groove 22 and the outer groove 24 are in communication with the inside of the substation box body 2, the controller starts the motor 3, causing the motor 3 to drive the first fan shaft 31 to rotate inside the substation box body 2, thereby accelerating the air circulation speed inside the substation box body 2 and further enhancing the heat dissipation effect;

[0042] Conversely, on a rainy day, the rain droplets are sensed by the rain droplet sensor 421. When the rainfall is large, the rain droplet sensor 421 can transmit a signal to the controller, and the controller controls the cylinder 41 to reset, causing the cylinder 41 to drive the top cover 42 to reset. Under the influence of gravity, the closing plate 4 is carried on the top of the top cover 42 and resets synchronously, and the closing plate 4 covers the top frame 21 and the exhaust groove 22, preventing rainwater from entering the inside of the substation box body 2 through the exhaust groove 22;

[0043] Meanwhile, during the reset process of the closing plate 4, the rubber plug 43 is driven to reset, causing the rubber plug 43 to slide inside the limiting tube 23 and the sealing box 44, reducing the space inside the limiting tube 23 and the sealing box 44 and increasing the air pressure. Then, the ejector rod 45 is pushed to slide and eject inside the sealing box 44, causing the ejector rod 45 to drive the connecting plate 46 to eject towards the outer groove 24, causing the connecting plate 46 to drive the connecting arm 48 to move towards the ventilation filter screen 27. Then, the ventilation filter screen 27 is detached from the inside of the outer groove 24 to the outside of the substation box body 2. At the same time, the connecting plate 46 drives the scraping plate 47 to be completely clamped inside the inner groove 241, closing the inner groove 241, and then preventing rainwater from entering the inside of the substation box body 2 through the outer groove 24. Thus, rainwater is prevented from entering the inside of the substation box body 2, improving the safety of the electrical equipment inside the substation box body 2;

[0044] Further, when the scraping plate 47 moves inside the inner groove 241, the inner wall of the inner groove 241 is cleaned by the scraping plate 47, so that dust and the like accumulated inside the inner groove 241 are swept outside the outer groove 24. At the same time, when the scraping plate 47 is completely clamped into the inner groove 241, the ventilation filter screen 27 is completely exposed outside the substation box body 2, that is, the ventilation filter screen 27 is completely exposed to rainwater. At this time, the ventilation filter screen 27 can be washed by rainwater, so that the blocked filter holes in the ventilation filter screen 27 can be cleaned and dredged. In this way, it is ensured that after the ventilation filter screen 27 is re-clamped into the inner part of the outer groove 24 subsequently, the air circulation between the inside and outside of the substation box body 2 can be improved, and the heat dissipation effect of the substation box body 2 is further improved.

[0045] It should be noted that, referring to Figure 3 , the top of the exhaust groove 22 is inclined, and filter holes are also provided on one side of the exhaust groove 22. Filter holes are also provided on both sides of the top frame 21 below the closing plate 4. Thus, when the closing plate 4 closes and shields the top frame 21, the hot air inside the substation box body 2 can still be discharged to the outside through the filter holes provided on one side of the exhaust groove 22 and 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, so there is no need to worry about rainwater entering the top of the substation box body 2 through the top frame 21.

[0046] Embodiment 2

[0047] The water cooling component includes a water delivery channel 5. The water delivery channel 5 is provided inside the closing plate 4 on the side away from the cabinet door. A water delivery pipe 51 is fixed on one side of the top of the substation box body 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 interconnected. A water pump 52 is fixed on one side of the top of the substation box body 2 close to the water delivery pipe 51, and the outlet pipe of the water pump 52 is communicated with the water delivery pipe 51. A cooling pipe 53 is fixed at the bottom of the water delivery pipe 51. A plurality of heat dissipation fins 54 are fixedly connected to the surface of the cooling pipe 53, and one side of the heat dissipation fins 54 is located inside the cooling pipe 53. One end of the cooling pipe 53 is fixedly connected to the inlet pipe of the water pump 52;

[0048] On the inner wall of the substation box body 2 close to the cabinet door, a second fan blade shaft 32 is rotatably connected. The second fan blade shaft 32 is drivingly connected to the first fan blade shaft 31 through a belt 33. One ends of the second fan blade shaft 32 and the first fan blade shaft 31 are both sealingly and rotatably connected to the cooling pipe 53. A linkage arc plate 34 is fixed at one end of the second fan blade shaft 32 and the first fan blade shaft 31 located inside the cooling pipe 53. A three-way pipe 6 is fixed at the bottom of the cooling pipe 53. Both ends of the bottom of the three-way pipe 6 pass through both sides of the substation box body 2. A storage groove 11 is formed inside the base 1. A protective frame 12 is slidably connected inside the storage groove 11. A drainage groove 13 is formed on the inner wall of the storage groove 11, and a one-way valve is provided in the drainage groove 13. Both ends of the bottom of the three-way pipe 6 respectively pass through the tops of both sides of the protective frame 12 and are located inside the storage groove 11;

[0049] Specifically, on the basis of Embodiment 1, when the cylinder 41 is fully reset, at this time, the top of the exhaust groove 22 and the inner groove 241 are in a completely closed state, while the top of the water inlet cavity 401 is in an open state. At this time, rainwater can accumulate inside the water inlet cavity 401 and enter the inside of the water delivery channel 5 through the water inlet cavity 401, and then enter the inside of the water delivery pipe 51 through the water delivery channel 5, so that the rainwater enters the inside of the cooling pipe 53 through the water delivery pipe 51. Subsequently, the water pump 52 is started through the controller, so that the water pump 52 sucks and pumps water for the cooling pipe 53, and then the rainwater circulates inside the cooling pipe 53;

[0050] When the rainwater circulates inside the cooling pipe 53, it passes through the heat dissipation fins 54 and cools the heat dissipation fins 54, taking away the heat adsorbed on the surface of the heat dissipation fins 54 from the equipment inside the substation box body 2. Thus, the effect of using rainwater to perform water-cooling heat dissipation on the electrical equipment inside the substation box body 2 is achieved, and when the outer groove 24 is in a completely closed state, the heat dissipation effect of the substation box body 2 is further improved;

[0051] Furthermore, when the rainwater circulates inside the cooling pipe 53, it impacts the linkage arc plate 34, causing the linkage arc plate 34 to rotate inside the cooling pipe 53. Then, the first fan blade shaft 31 and the second fan blade shaft 32 are driven to rotate through the linkage arc plate 34. At this time, the power supply drive to the first fan blade shaft 31 by the motor 3 is stopped, so that the first fan blade shaft 31 and the second fan blade shaft 32 rotate without power consumption, thereby strengthening the heat dissipation of the substation box body 2 and cooperating with the water-cooling of the rainwater, further strengthening the heat dissipation effect of the substation box body 2;

[0052] Further, when the rainwater temperature in the cooling pipe 53 is insufficient for effective heat dissipation, or when the rainfall is large 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 receiving groove 11 through the three-way pipe 6. When the rainwater accumulates in the receiving groove 11, affected by the buoyancy, the rainwater lifts the protective frame 12, causing the protective frame 12 to float out of the receiving groove 11 and seal the gap of the cabinet door of the substation box body 2 until the protective frame 12 is limited at both ends of the three-way pipe 6 and cannot continue to eject. At this time, the protective frame 12 protects the cabinet door of the substation box body 2, increasing the minimum height of the gap of the cabinet door of the substation box body 2, thereby avoiding too high ground water level and reducing the possibility of surface water entering the interior of the substation box body 2 through the gap of the cabinet door of the substation box body 2, and further improving the protection effect on the substation box body 2;

[0053] Meanwhile, as the rainwater is injected into the receiving groove 11, the weight of the base 1 increases. Since the base 1 is fixedly connected to the substation box body 2, the weight of the substation box body 2 is indirectly increased, making the substation box body 2 more stable, ensuring the stability of the substation box body 2 during waterlogging, preventing the substation box body 2 from being washed away by the rainwater of waterlogging, and thus playing a role in protecting the substation box body 2. When the rainy day or waterlogging ends, the rainwater in the receiving groove 11 can be discharged through the drain groove 13, then the protective frame 12 is reset, and the cabinet door of the substation box body 2 is unshielded.

[0054] It should be noted that the second fan shaft 32 is drivingly connected to the first fan shaft 31 through the belt 33. That is, in the first embodiment, when the motor 3 is started and the motor 3 drives the first fan shaft 31 to rotate, the first fan shaft 31 drives the second fan shaft 32 to rotate synchronously through the belt 33, and then the first fan shaft 31 and the second fan shaft 32 rotate synchronously inside the substation box body 2, further improving the heat dissipation effect of the substation box body 2;

[0055] A one-way valve is provided inside the end of the water delivery pipe 51 connected to the water delivery channel 5, enabling the water delivery pipe 51 to control the replacement of the rainwater in the cooling pipe 53. After the rainwater in the cooling pipe 53 reaches a certain temperature, cooler rainwater is delivered into the cooling pipe 53 through the water delivery pipe 51. A one-way valve is also provided inside the three-way pipe 6, enabling the three-way pipe 6 to communicate with the cooling pipe 53 through the one-way valve inside the three-way pipe 6 when the rainwater in the cooling pipe 53 needs to be replaced or when water is injected into the receiving groove 11.

[0056] Embodiment 3

[0057] On both sides of the top of the closing plate 4, there are fixed vertical frames 7. On both sides of the vertical frames 7, there are rotatably connected snow-clearing plates 71. The bottom ends of the snow-clearing plates 71 are inclined. On the surfaces at both ends of the closing plate 4, there are rotatably connected movable plates 72, and the two movable plates 72 are respectively located at the tops of both ends of the closing plate 4. One end of the movable plate 72 close to the snow-clearing plate 71 is inclined;

[0058] During the specific operation process, when it snows, since the top cover 42 and the movable plate 72 are completely exposed to the air, snow accumulates on the tops of the movable plate 72 and the top cover 42. At this time, the controller controls the cylinder 41 to start and reset repeatedly. The cylinder 41 drives the top cover 42 to eject and reset repeatedly. During this process, the top cover 42 repeatedly contacts the top of the water inlet cavity 401 and vibrates. Thus, the snow on the top of the top cover 42 can be gradually shaken off and fall into the interior of the water inlet cavity 401. When the snow melts, it can be used as a cooling liquid, and according to the operation of Embodiment 2, heat dissipation operation is carried out on the interior of the substation box body 2, further improving the heat dissipation effect of the substation box body 2;

[0059] Furthermore, after the snow on the top of the top cover 42 is shaken off, maintaining the state where the top cover 42 repeatedly touches the water inlet cavity 401, 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 in vibrating the snow-clearing plate 71, gradually releasing the frozen state of the snow-clearing plate 71. When the top cover 42 is completely reset, the snow-clearing plate 71 in the unfrozen state resets under the action of gravity. The snow-clearing plate 71 is perpendicular to the bottom of the water inlet cavity 401, thereby causing the movable plate 72 to lose the limit support of the snow-clearing plate 71. Under the action of gravity, the movable plate 72 flips and falls back to abut against the surface of the closing plate 4. During the process of the movable plate 72 flipping and falling back, the movable plate 72 also vibrates, which can loosen the snow on the top of the movable plate 72;

[0060] Subsequently, when the top cover 42 is ejected again, it can contact the snow-clearing plate 71, causing the top cover 42 to drive the snow-clearing plate 71 to gradually flip towards the direction of the movable plate 72. Until after the snow-clearing plate 71 contacts the movable plate 72, it drives the movable plate 72 to flip, thereby causing the movable plate 72 to drive the snow on its 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, thereby gradually loosening and sliding the snow on the top of the movable plate 72. Thus, the present invention can perform snow-clearing operations on the tops of the movable plate 72 and the top cover 42 when it snows, avoiding excessive load on the substation box body 2 and damage and failure, and at the same time avoiding the blockage of the rain droplet sensor 421 by snow, ensuring the accuracy of the rain droplet sensor 421 in sensing rain droplets in the later stage.

[0061] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
