DETAILED DESCRIPTION

[0028] Embodiment 1, as Figure 1-Figure 9 As shown, a modular mobile energy-saving substation proposed in this embodiment includes a box assembly, a dehumidification and ventilation device, a water tank 22 and a cleaning device.

[0029] like Figure 1 and Figure 2As shown, the box assembly includes a bottom box 3, a top box 1 located above the bottom box 3, and a plurality of connecting boxes 2 stacked and connected between the bottom box 3 and the top box 1. There is at least one connecting box 2, and the number of connecting boxes 2 is selected according to the number and size of the electrical components required inside the substation to ensure that all electrical components can be installed in the bottom box 3, the connecting box 2 and the top box 1. A base 4 is provided at the bottom of the bottom box 3, and a foot cup 5 is provided at the bottom of the base 4 for easy movement and fixation. A bracket 25 is provided at the top of the top box 1, and a solar panel 26 is tiltedly provided on the top of the bracket 25. The solar panel 26 is electrically connected to a battery, and the electricity generated by the solar panel 26 is stored in the battery. The top of the bottom box 3 is connected with a flange pipe a301, the bottom of the top box 1 is connected with a flange pipe d101, the bottom of the connecting box 2 is connected with a flange pipe b201 detachably connected to the flange pipe a301, and the top of the connecting box 2 is connected with a flange pipe c202 detachably connected to the flange pipe d101. Each electrical component is routed through the flange pipe, and each flange pipe is provided with a through hole, which is detachably connected by bolts and nuts, thereby realizing the modular connection of the connecting box 2. If there is only one connecting box 2, it is directly connected between the bottom box 3 and the top box 1; if there are multiple connecting boxes 2, the multiple connecting boxes 2 are stacked and distributed and connected in sequence through the flange pipe c202 and the flange pipe b201, the connecting box 2 at the bottom is connected to the bottom box 3, and the connecting box 2 at the top is connected to the top box 1.

[0030] like Figure 3 and Figure 4 As shown, the dehumidification ventilation device includes a ventilation pipe 6 which is arranged on the top box 1 and has two air inlet ends and one air outlet end, a fan 7 which is arranged at the air outlet end of the ventilation pipe 6, a filter 17 which is arranged at one air inlet end of the ventilation pipe 6, a mounting pipe 8 which is arranged vertically and is connected to the other air inlet end of the ventilation pipe 6, a dehumidification assembly which is arranged on the lower part of the mounting pipe 8, a condensation plate 18 which is arranged on the inner side of the mounting pipe 8, and a drip pipe 21 which is connected to the bottom of the mounting pipe 8, and the ventilation pipe 6 has mesh holes, and the condensation plate 18 is a cone-shaped structure with the cone top facing upward and is located above the dehumidification assembly. The battery can provide electric energy for the fan 7. When the fan 7 is running, air is drawn from the ventilation pipe 6, and negative air pressure is generated in the ventilation pipe 6. The hot air in the bottom box 3 and the connecting box 2 flows upward to the top box 1, and the hot air in the top box 1 enters the ventilation pipe 6 through the mesh holes on the ventilation pipe 6, so that the hot air can be discharged from the top box 1, and the heat dissipation of each box is realized. In addition, at night, when the outside air flows from the dehumidification assembly, the moisture in the outside air is adsorbed by the dehumidification assembly. When the temperature is high during the day, the moisture adsorbed in the dehumidification assembly evaporates and is condensed into water droplets by the condensation plate 18 . The water droplets flow downward along the condensation plate 18 and the inner wall of the installation pipe 8 , and flow downward through the drip pipe 21 .

[0031] like Figure 3 , Figure 5 and Figure 6As shown, the water tank 22 is arranged on the top box 1 and is connected to the drip pipe 21, and can collect condensed water drops. The top of the water tank 22 is connected to a rain collecting hopper 23, the top of which is provided with a filter screen, the bottom of which is provided with a magnet a231, the bottom of which is an inclined surface, and a blocking plate 24 with an inclined distribution is rotatably installed at the higher end of the bottom of the rain collecting hopper 23, the blocking plate 24 is provided with a magnet b241 that is magnetically attracted to the magnet a231, and the outer end of the blocking plate 24 is connected to a limit rod 242 that can abut against the bottom of the rain collecting hopper 23. On rainy days, rainwater passes through the filter and enters the rain collecting hopper 23, the rainwater flushes open the blocking plate 24, the magnet b241 separates from the magnet a231, and the limiting rod 242 abuts against the outer surface of the rain collecting hopper 23, so that there is still a suction force between the magnet a231 and the magnet b241 that is sufficient to drive the blocking plate 24 to reset. When the rain stops or the rain is not enough to flush open the blocking plate 24, the magnet a231 attracts the magnet b241, and the magnet b241 drives the blocking plate 24 to rotate in the opposite direction and reset. The blocking plate 24 is re-sealed at the bottom of the rain collecting hopper 23 to prevent the waste of water in the water tank 22 due to evaporation.

[0032] The cleaning device is connected to the water tank 22 and sprays water or air to the solar panel 26. When there is water in the water tank 22, the cleaning device draws water from the water tank 22 and sprays water to the solar panel 26 for cleaning. When there is no water in the water tank 22, the cleaning device draws air and sprays air to the solar panel 26 for jet cleaning. Regardless of whether there is water or not, the solar panel 26 can be effectively cleaned to ensure the cleanliness of the surface of the solar panel 26 and the efficiency of the solar panel 26 in converting solar energy.

[0033] This embodiment can convert moisture in the air into water for cleaning the solar panel 26, and can clean the solar panel 26 by blowing air after the water is used up. On the one hand, the dehumidification ventilation device can discharge the hot air in the substation to achieve heat dissipation and ensure the normal operation of the internal electrical components; on the other hand, the dehumidification ventilation device can convert moisture in the air into water and store it in the water tank 22. The cleaning device can spray water to clean the solar panel 26 by extracting water from the water tank 22. After the water is used up, the cleaning device can also clean the solar panel 26 by jetting air, ensuring the efficiency and quality of the solar panel 26 in converting solar energy.

[0034] Embodiment 2, as Figure 1-Figure 9 As shown, a modular mobile energy-saving substation proposed in this embodiment, compared with the first embodiment, in this embodiment, the ventilation pipe 6 includes a straight pipe portion 61 horizontally penetrating the top box 1 and a connecting pipe portion 62 connected to the bottom end of the straight pipe portion 61, the bottom end of the connecting pipe portion 62 penetrates the top box 1, the meshes are distributed on the straight pipe portion 61, and the fan 7 and the filter 17 are respectively located at both ends of the straight pipe portion 61. The fan 7 exhausts air outward, and the filter 17 plays a filtering role to filter the air entering the straight pipe portion 61.

[0035] like Figure 4 As shown, the dehumidification component includes an outer cylinder 9 installed through the bottom of the installation tube 8, a filter plate a12 and a filter plate b13 respectively connected to the bottom and top of the outer cylinder 9, an inner cylinder 10 connected between the filter plate a12 and the filter plate b13 and located on the inner side of the outer cylinder 9, and an adsorption material 11 filled between the outer cylinder 9 and the inner cylinder 10. The adsorption material 11 is made of calcium chloride particles, which can absorb moisture in the air.

[0036] like Figure 3 and Figure 4 As shown, the substation also includes a switching assembly, which includes a lifting frame 15 vertically penetrating the installation tube 8, a baffle 16 connected to the lifting frame 15, an electric push rod 14 arranged on the top box 1 and drivingly connected to the lifting frame 15, a connecting rod 19 vertically arranged at the bottom of the condensation plate 18, and a sealing plug 20 arranged at the bottom end of the connecting rod 19. The bottom end of the lifting frame 15 is connected to the condensation plate 18, the inner bottom surface of the installation tube 8 is an inclined surface, and the lower end of the inclined surface has a circular hole, the sealing plug 20 is adapted to the circular hole, the inner diameter of the drip pipe 21 is larger than the diameter of the circular hole, and the outer edge of the condensation plate 18 contacts the inner edge of the installation tube 8. The battery can provide electric energy for the electric push rod 14, the electric push rod 14 drives the lifting frame 15 to rise and fall, and the lifting frame 15 can drive the baffle 16, the condensation plate 18, the connecting rod 19 and the sealing plug 20 to rise and fall. When the water in the adsorption material 11 evaporates, the water vapor flows upward to the condensation plate 18 and condenses into water droplets. The water droplets fall along the bottom surface of the condensation plate 18 and the inner wall of the mounting tube 8, and can flow smoothly to the circular hole. After the sealing plug 20 is moved downward from the circular hole, the water will flow downward along the gap between the sealing plug 20 and the inner wall of the drip pipe 21, and finally flow into the water tank 22.

[0037] Furthermore, a clock and a central controller are provided on the top box 1, and the clock is connected to the central controller in communication, and the central controller controls the extension and retraction of the electric push rod 14 according to the time. When the humidity is heavy at night, the baffle 16 blocks the filter 17, and the condensation plate 18 is higher than the connection point between the connecting pipe part 62 and the installation pipe 8. When the fan 7 blows outward, negative air pressure is generated in the straight pipe part 61 and the connecting pipe part 62. The outside air enters the installation pipe 8 through the dehumidification component, and enters the straight pipe part 61 through the connecting pipe part 62. The moisture in the outside air has been subjected to the moisture absorption treatment of the adsorption material 11. At this time, the sealing plug 20 is blocked at the circular hole at the bottom of the installation pipe 8. When the temperature is high during the day, the condensation plate 18 moves downward, and the condensation plate 18 is lower than the connection point between the connecting pipe portion 62 and the installation pipe 8. The baffle 16 moves downward from the filter 17. When the fan 7 blows air outward, air is drawn from the filter 17. The water in the adsorption material 11 evaporates due to the heat. After the water vapor is condensed by the condensation plate 18, it flows to the circular hole. The sealing plug 20 moves downward to the drip pipe 21. The water flows downward through the circular hole and continues to flow downward through the gap between the sealing plug 20 and the inner wall of the drip pipe 21 until it flows into the water tank 22.

When the nozzle 34 moves back and forth, the row of spray holes 341 on the front side of the moving direction first sprays water or air to perform preliminary cleaning, and then the cleaning brush 35 scrapes the surface of the solar panel 26 for secondary cleaning, and then the row of spray holes 341 on the rear side of the moving direction sprays water or air to clean the scraped dirt, so as to achieve the third cleaning, and the triple cleaning effect is better.
