[0002] A prefabricated substation, also often referred to as a box-type substation, combines and installs main electrical equipment such as high-voltage switchgear, transformers, and low-voltage switchgear in one or several enclosed boxes according to a certain wiring method.

[0016] Compared with the related art, the prefabricated substation provided by the present invention has the following beneficial effects: The present invention provides a prefabricated substation. Through the cooperation of the first water collecting tank, the second filter screen, the gutter water tank, the drain pipe and the second water collecting tank, in rainy days, through the two gutter water tanks, the second water collecting tank and the first water collecting tank can collect natural rainwater resources, reducing the dependence on other water sources such as municipal water supply. When there is a need for cleaning substation equipment in the future, the collected rainwater can be used, thus saving water costs; through the cooperation of the first pipe, the first pump body, the heat absorbing plate, the cooling pipe, the heat dissipation groove and the heat dissipation port, when the substation is operating, the heat absorbing plate inside will absorb a large amount of heat. Using the rainwater to circulate through the heat absorbing plate can take away the heat and thus achieve effective heat dissipation, keeping the internal temperature of the substation in a more reasonable range, avoiding that too high temperature is likely to cause the performance of electrical equipment to decline, the service life to be shortened or even failures to occur, and compared with using traditional refrigeration and heat dissipation equipment to control the temperature, using natural cold source of rainwater for heat exchange to dissipate heat can reduce energy consumption to a certain extent; Through the cooperation of the transparent plate, dust box, sliding plate, fixed frame, spring, third filter, first guide rod and movable frame, since rainwater often carries dust, leaves, small particles and other impurities when falling from the sky to the ground, the third filter can intercept these impurities to prevent them from entering the pipes and equipment used for subsequent heat dissipation and cleaning and causing blockage, ensuring that rainwater can circulate smoothly and perform heat exchange operations, and secondly reducing the corrosion and other damage to the device itself and the pipeline caused by the long-term accumulation of impurities; through the pressure sensor, dustproof plate, first servo motor, second belt, rotating The column, gear and first bearing cooperate with each other. When dust and impurities accumulate to a certain amount, they will block the pores of the filter, resulting in reduced filtration efficiency and poor water flow. As impurities accumulate, the movable frame gradually drops and conflicts with the pressure sensor. When the pressure sensor reaches the trigger value, it sends a signal to the external motor control device, which then drives the first servo motor to operate, so that these blockages can be automatically cleared, allowing the third filter to always maintain good filtration capabilities and continuously and effectively intercept impurities. There is no need for manual frequent inspection of filter blockage and manual cleaning, saving manpower and time costs. Through the cooperation of the first screw, the second screw, the second servo motor, the first belt, the lifting plate, the cleaning brush, the slot and the second guide rod, since the substation is exposed to the outside for a long time, the outer wall is easily contaminated with dust, stains, bird droppings, etc., and the lifting plate can be regularly cleaned by the cleaning brush when it is lifted, so that the appearance of the substation is kept clean and tidy, and some corrosive stains and dust are prevented from adhering to the outer wall for a long time to corrode the outer shell material of the substation. Secondly, dust and the like cover the outer wall of the substation, which will affect its heat dissipation performance to a certain extent. Through regular cleaning, the obstacles to heat dissipation from the outer wall can be reduced, thereby ensuring the substation The heat generated by the internal electrical equipment can be better dissipated; through the cooperation of the second pump body, the second pipe, the waterproof plate, the diversion seat and the water spray pipe, the nozzle sprays rainwater evenly onto the outer wall of the substation body. Compared with simple wiping and other methods, it can more comprehensively cover every corner of the outer wall of the substation, better wash away dust, stains, bird droppings and other dirt, and improve the cleaning effect. Secondly, the sprayed water will take away heat when it evaporates. When the weather is hot, rainwater is sprayed onto the outer wall surface. The water evaporation process helps to take away part of the heat emitted from the outer wall and the inside of the substation, and plays a certain auxiliary heat dissipation role.

Detailed implementation manners

[0019] The present invention will be further described below in conjunction with the accompanying drawings and implementation manners.

[0020] First embodiment: Please refer to Figures 1 - 5, in the first embodiment of the present invention, the prefabricated substation includes: a substation body 1, a waterproof roof 7, and a plurality of first filters 2. The waterproof roof 7 is fixedly installed on the top of the substation body 1, and the plurality of first filters 2 are all fixedly installed on the substation body 1. Gutters 5 are fixedly installed on both sides of the waterproof roof 7, and second filters 6 are fixedly installed on the tops of the two gutters 5. When rainwater flows along the waterproof roof into the gutters 5, larger impurities or fallen leaves can be isolated to prevent them from entering the first water collection tank 4 and the second water collection tank 11. A first water collection tank 4 and a second water collection tank 11 are respectively fixedly installed on both sides of the substation body 1. Heat sinks 49 are fixedly installed at the bottoms of the first water collection tank 4 and the second water collection tank 11. One end of a connecting pipe 50 is fixedly installed on one side of the first water collection tank 4, and the other end of the connecting pipe 50 is fixedly connected to the second water collection tank 11. Through the connecting pipe 50, the first water collection tank 4 and the second water collection tank 11 can be integrated into a larger water storage space, and the coolant can flow and mix with each other through the connecting pipe 50 to make the temperatures of the two tend to be the same, ensuring the stability and uniformity of the cooling effect. Drain pipes 13 are fixedly installed at the bottoms of the two gutters 5, and the other ends of the two drain pipes 13 respectively extend into the first water collection tank 4 and the second water collection tank 11. An endothermic plate 19 is fixedly installed inside the substation body 1, and a cooling pipe 12 is fixedly installed on the top of the endothermic plate 19. When rainwater is pumped into the cooling pipe 12, the endothermic plate 19 transfers the absorbed heat to the surface of the cooling pipe 12, and the cooling pipe 12 absorbs and takes away the heat through the rainwater, thereby quickly reducing the temperature inside the substation body 1. One end of the cooling pipe 12 penetrates the substation body 1 and extends into the first water collection tank 4. A first pump body 17 is fixedly installed at the bottom of the waterproof roof 7. The water inlet end of the first pump body 17 is fixedly installed with a first pipe 16, and the other end of the first pipe 16 is fixedly connected to the first water collection tank 4. The other end of the cooling pipe 12 is fixedly installed at the water outlet end of the first pump body 17. The other end of the first pipe 16 at the inlet end of the first pump body 17 is fixedly connected to the first water collection tank 4. A limiting baffle 15 is fixedly installed inside the substation body 1, and a plurality of fans 14 are fixedly installed on the side of the limiting baffle 15 away from the first filter 2.

[0021] The waterproof roof 7 is provided with two inclined surfaces, and a number of drinking troughs are opened on both inclined surfaces. Through such a layout, rainwater can flow into the gutters 5 quickly and accurately, facilitating subsequent collection.

[0022] A plurality of ventilation openings 3 are provided on the substation body 1, and the plurality of first filters 2 are respectively fixedly installed in the plurality of ventilation openings 3.

[0023] A plurality of heat dissipation openings 21 are provided on the endothermic plate 19, and a heat dissipation groove 20 is further provided on the top of the endothermic plate 19. The cooling pipe 12 is located in the heat dissipation groove 20, and the outer wall of the cooling pipe 12 is in contact with the heat dissipation groove 20.

[0024] The working principle of the prefabricated substation provided by the present invention is as follows: When it rains, rainwater flows along the waterproof roof 7 into the two gutter water tanks 5. At this time, the second filter screen 6 isolates impurities and leaves, and the rainwater flows into the first water collection tank 4 through the drain pipe 13 and is concentrated.

[0025] When the temperature inside the substation body 1 is relatively high and heat dissipation is required, the first pump body 17 is started. The first pump body 17 extracts the rainwater in the first water collection tank 4 through the first pipeline 16 and transports it to the cooling pipe 12. The heat generated by the equipment inside the substation body 1 rises and is absorbed by the heat absorption plate 19. At this time, the heat absorbed by the heat absorption plate 19 is absorbed and carried away through the cooling pipe 12. The rainwater circulates in the cooling pipe 12 and finally drains back into the first water collection tank 4 again to be mixed with cold water. Then, the fan 14 is started, and the fan 14 extracts the cold air outside the substation body 1 into the substation body 1, so as to further dissipate heat inside the substation body 1. Through the connecting pipe 50, the first water collection tank 4 and the second water collection tank 11 can be integrated into a larger water storage space, reducing the situation of rainwater overflowing the box body, etc. When there is a temperature difference between the coolants in the two cooling boxes, the coolants can flow and mix with each other through the connecting pipe 50 to make their temperatures tend to be the same, ensuring the stability and uniformity of the cooling effect.

[0026] Compared with the related technology, the prefabricated substation provided by the present invention has the following beneficial effects: Through the cooperation of the first water collection tank 4, the second filter screen 6, the gutter water tank 5, the drain pipe 13 and the second water collection tank 11, when it rains, through the two gutter water tanks 5, the second water collection tank 11 and the first water collection tank 4 can collect natural rainwater resources, reducing the dependence on other water sources such as municipal water supply. When there is a need for cleaning substation equipment in the future, the collected rainwater can be used, thus saving water costs; through the cooperation of the first pipeline 16, the first pump body 17, the heat absorption plate 19, the cooling pipe 12, the heat dissipation groove 20 and the heat dissipation port 21, when the substation is operating, the heat absorption plate inside will absorb a large amount of heat. Using rainwater to circulate through the heat absorption plate can take away the heat and thus achieve effective heat dissipation, keeping the temperature inside the substation within a more reasonable range, avoiding the situation that too high temperature easily leads to the decline of the performance of electrical equipment, shortening of the service life or even failure, and compared with using traditional refrigeration and heat dissipation equipment to control the temperature, using rainwater, a natural cold source, for heat exchange to dissipate heat can reduce energy consumption to a certain extent.

[0027] Second Embodiment: Based on the prefabricated substation provided in the first embodiment of the present application, the second embodiment of the present application proposes another prefabricated substation. The second embodiment is merely a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0028] The second embodiment of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Please refer to Figures 6 - 15 , the prefabricated substation further includes two dust collection boxes 24 respectively and fixedly installed on the second water collection tank 11 and the first water collection tank 4. The bottom of each of the two dust collection boxes 24 is slidably installed with a sliding plate 31. When there is too much impurity in the dust collection box 24, it can be observed through the transparent plate 25, and then the sliding plate 31 at the bottom is pulled to quickly clean the impurities inside. Openings are provided on the sides of the second water collection tank 11 and the first water collection tank 4 away from each other, and dust-proof plates 26 are hinged. One end of each of the two dust-proof plates 26 is fixedly installed with a first connecting rod 27. Rotating columns 36 are rotatably installed on one side of the second water collection tank 11 and the first water collection tank 4. Gears 30 are fixedly installed on the outer walls of the rotating columns 36 and the outer walls of the first connecting rods 27. The two gears 30 are meshed with each other. Fixed frames 35 are hinged in the second water collection tank 11 and the first water collection tank 4. Second connecting rods 38 are fixedly installed at both ends of the fixed frame 35. First servo motors 28 are fixedly installed on both sides of the second water collection tank 11 and the first water collection tank 4. The output shafts of the two first servo motors 28 are respectively fixedly connected to the two second connecting rods 38. First belt pulleys are fixedly installed on the outer sides of the output shafts of the first servo motors 28 and the outer sides of the rotating columns 36. The same second belt 42 is sleeved on the outer sides of the two first belt pulleys. When the two gears 30 are rotated simultaneously by the second belt 42, the dust-proof plate 26 can be opened while the fixed frame 35 rotates. An activity frame 34 is slidably installed in the fixed frame 35. A pressure sensor 32 is fixedly installed on the bottom inner wall of the fixed frame (35). As the impurities accumulate, the activity frame 34 gradually descends and finally contacts the pressure sensor 32. When the pressure applied by the activity frame 34 reaches the trigger value of the pressure sensor 32, it will send a signal to the external motor control device, and the external motor control device then drives the first servo motor 28 to operate. At this time, the dust-proof plate 26 is opened through the second belt 42, and then the activity frame 34 is driven to rotate, and the dust and impurities above are thrown into the dust collection box 24 by centrifugal force to realize the self-cleaning function. Three third filters 33 are hinged in the activity frame 34, and three limiting blocks are fixedly installed on the inner wall of the activity frame 34, and the three limiting blocks are respectively located at the bottoms of the three third filters 33.

[0030] Observation ports are provided on the sides of the two dust collection boxes 24 away from each other, and transparent plates 25 are fixedly installed in the observation ports. The impurities in the dust collection box 24 can be clearly seen through the transparent plates 25, thus facilitating cleaning.

[0031] First bearings 29 are rotatably installed on the outer walls of the two first connecting rods 27, and the outer walls of the two first bearings 29 are respectively fixedly installed on the first water collection tank 4 and the second water collection tank 11.

[0032] A first guide rod 41 is fixedly installed in the fixed frame 35 , and the movable frame 34 is slidably installed on the first guide rod 41 . A spring 39 is provided on the outer wall of the first guide rod 41 , and both ends of the spring 39 are fixedly connected to the movable frame 34 and the fixed frame 35 respectively.

[0033] When rainwater is discharged into the second water collecting tank 11 and the first water collecting tank 4 through the drain pipe 13, impurities in the rainwater will be intercepted on the three third filter screens 33. When a certain amount of impurities are accumulated on the three third filter screens 33, the weight of the accumulated dust causes the movable frame 34 to drop, and the movable frame 34 contacts the pressure sensor 32. At this time, the first servo motor 28 is started, and the output shaft of the first servo motor 28 drives the fixed frame 35 to rotate, and at the same time drives the rotating column 36 to rotate through the second belt 42, so that the two gears 30 rotate and the dustproof plate 26 is opened. Since the third filter screen 33 is hinged on the movable frame 34, when the fixed frame 35 rotates to the outside of the second water collecting tank 11 or the first water collecting tank 4, the third filter screen 33 is opened, and the impurities and dust on the third filter screen 33 are poured into the dust collecting box 24. Then the first servo motor 28 rotates the fixed frame 35 to the second water collecting tank 11 or the first water collecting tank 4 again, and the dustproof plate 26 is closed. When it is necessary to clean the dust collecting box 24, the sliding The plate 31 is sufficient. Through the arrangement of the above-mentioned components, the present invention can intercept impurities such as dust, leaves, and small particles of debris that are carried along by rainwater in the process of falling from the sky to the ground, and prevent them from entering the subsequent pipes and equipment used for heat dissipation and cleaning and causing blockage, thereby ensuring that rainwater can smoothly circulate and perform heat exchange operations. Secondly, it reduces the damage such as corrosion to the device itself and the pipeline caused by the long-term accumulation of impurities. When the dust impurities accumulate to a certain amount, they will block the pores of the filter, resulting in a decrease in filtration efficiency and poor water flow. As impurities accumulate, the movable frame 34 gradually descends and conflicts with the pressure sensor 32. When the pressure sensor 32 reaches the trigger value, it sends a signal to the external motor control device, which then drives the first servo motor 28 to operate, thereby automatically clearing these blockages, allowing the third filter 33 to always maintain a good filtration capacity, continuously and effectively intercept impurities, and there is no need for manual frequent inspection of the filter blockage and manual cleaning, saving manpower and time costs.

[0034] Third embodiment: Based on the prefabricated substation provided in the second embodiment of the present application, the third embodiment of the present application provides another prefabricated substation. The third embodiment is only a preferred embodiment of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0035] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0036] Please refer toFigures 16 - 19 In the prefabricated substation provided in this embodiment, it further includes a slot 44 and a fixing plate 46 fixedly installed outside the substation body 1. Four second guide rods 43 are fixedly installed at the top of the slot 44, and the other ends of the four second guide rods 43 are fixedly connected to the fixing plate 46. The same lifting plate 45 is slidably installed on the outer sides of the four second guide rods 43. A cleaning brush 8 and two water spray pipes 10 are fixedly installed on one side of the lifting plate 45 close to the substation body 1. When the lifting plate 45 moves up and down, the cleaning brush 8 can regularly clean it, keeping the appearance of the substation clean and tidy, and preventing some corrosive stains and dust from adhering to the outer wall for a long time and corroding the outer shell material of the substation. One end of the two water spray pipes 10 close to each other is fixedly installed with the same flow dividing seat 9. The flow dividing seat 9 can evenly distribute water into the two water spray pipes 10. A plurality of nozzles are fixedly installed on one side of the two water spray pipes 10 close to the substation body 1. While spraying water, the plurality of nozzles cooperate with the cleaning brush 8 to better wash away dirt such as dust, stains, and bird droppings, improving the cleaning effect. Moreover, the sprayed water will take away heat when evaporating. When the weather is hot, spraying rainwater on the outer wall surface helps to take away part of the heat dissipated from the outer wall and the interior of the substation, playing a certain role in auxiliary heat dissipation. A second pump body 37 is fixedly installed at the top of the fixing plate 46. The outlet end and the inlet end of the second pump body 37 are both fixedly installed with a second pipe 40. The other end of the second pipe 40 at the outlet end of the second pump body 37 is fixedly connected to the flow dividing seat 9, and the other end of the second pipe 40 at the inlet end of the second pump body 37 is fixedly connected to the second water collecting tank 11. A second screw rod 48 is rotatably installed at the top of the slot 44. The lifting plate 45 is threadedly connected to the outer side of the second screw rod 48. A second servo motor 47 is fixedly installed at the top of the fixing plate 46, and the output shaft of the second servo motor 47 is fixedly connected to the second screw rod 48. A first screw rod 22 is rotatably installed in the substation body 1. A waterproof plate 18 is threadedly connected to the outer side of the first screw rod 22. The waterproof plate 18 is located within the limit baffle 15. Second belt pulleys are fixedly installed on the outer sides of the output shaft of the second servo motor 47 and the outer side of the first screw rod 22, and the same first belt 23 is sleeved on the outer sides of the two second belt pulleys.

[0037] The threads of the first screw rod 22 and the second screw rod 48 are arranged in opposite directions. Through this opposite arrangement, while the lifting plate 45 rises, the waterproof plate 18 descends, preventing water from entering the substation body 1 through the ventilation opening 3 when cleaning the outer wall of the substation body 1.

[0038] In this embodiment, when it is necessary to clean the outer wall of the substation body 1 or spray water on the outer wall of the substation body 1 for heat dissipation, the second pump body 37 is started. The second pump body 37 extracts the water in the second water collecting tank 11 through the second pipeline 40 and transports it to the flow dividing seat 9 through the second pipeline 40. The flow dividing seat 9 evenly distributes the water into the two spray pipes 10, and finally the water sprays out from multiple nozzles. Subsequently, the second servo motor 47 is started, and the output shaft of the second servo motor 47 drives the second screw rod 48 to rotate, and at the same time drives the first screw rod 22 to rotate through the first belt 23, so that the lifting plate 45 rises and the waterproof plate 18 descends. When the waterproof plate 18 descends, it blocks the ventilation opening 3. When the lifting plate 45 rises, the cleaning brush 8 cooperates with the nozzle to clean and dissipate heat from the outer wall of the substation body 1. Through the arrangement of the above components of the present invention, since the substation is exposed outdoors for a long time, the outer wall is prone to be contaminated with dust, stains, bird droppings, etc. When the lifting plate 45 rises and falls, the cleaning brush 8 can regularly clean it, keeping the appearance of the substation clean and tidy, and avoiding some corrosive stains and dust from adhering to the outer wall for a long time and corroding the outer shell material of the substation. Secondly, dust and the like covering the outer wall of the substation will, to a certain extent, affect its heat dissipation performance. Through regular cleaning, the obstruction of heat dissipation from the outer wall can be reduced, ensuring that the heat generated by the electrical equipment inside the substation can be better dissipated. The nozzles evenly spray rainwater on the outer wall of the substation body 1, which can cover all corners of the outer wall of the substation more comprehensively than simple wiping and other methods, and can better wash away dust, stains, bird droppings and other dirt, improving the cleaning effect. Secondly, the sprayed water will take away heat when it evaporates. In hot weather, spraying rainwater on the outer wall surface, the evaporation process of the water helps to take away part of the heat radiated from the outer wall and the inside of the substation, playing a certain role in auxiliary heat dissipation.

[0039] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present invention.
