DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] The present invention provides a waterproof mobile power conversion device, such as Figures 1 to 9 As shown, it includes a mobile substation chassis 1, an installation compartment 2, a circuit breaker 3, a transformer 4, a capacitor 5, and a plurality of wiring harness boxes 6.

[0038] Working principles of the above components: The circuit breaker 3, transformer 4, and capacitor 5 are all common standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. At the same time, the circuit connections and usage methods of these components can also be known through technical manuals or conventional experimental methods.

[0039] like Figure 1 As shown in the figure, a roller is arranged at the bottom of the mobile substation chassis 1, and a connecting frame is arranged on one side of the mobile substation chassis 1, so that the mobile substation chassis 1 and the components thereon can be moved by a vehicle. Figure 1 In the figure, it can be seen that the mobile substation equipment chassis 1 is provided with hydraulic rods, and when the mobile substation equipment chassis 1 is fixed at a certain location, the hydraulic rods are used to provide support for the mobile substation equipment chassis 1.

[0040] The inner wall of the rotating shell 12 is installed with a waterproof device, which is used to prevent water from flowing into the installation bin 2 along the line. The waterproof device includes: a fixed shell 13, a moving ring 15, a fixed column 16, and an electromagnet 18;

[0041] The outer walls on both sides of the installation bin 2 are rotatably connected with rotating leaves 7, a first fixing frame 8 is fixedly installed on the outer wall of the rotating leaf 7 close to the installation bin 2, a connecting groove 9 is fixedly installed on the side of the first fixing frame 8 away from the rotating leaf 7, a plurality of moving blocks 10 are slidably connected to the inner wall of the connecting groove 9 away from the first fixing frame 8, a plurality of moving blocks 10 are rotatably connected to the outer walls of the sides away from the connecting groove 9, a rotating shell 12 is rotatably connected to the outer wall of the rotating block 11 away from the moving block 10, a through hole is provided in the middle of the water-absorbing sponge 14, a rubber ring 20 is fixedly installed on the inner wall of the fixed shell 13 away from the water-absorbing sponge 14, an opening 21 is provided on the bottom outer wall of the fixed shell 13 close to the water-absorbing sponge 14, a second fixing ring 19 is sleeved on the inner ring of the electromagnet 18, and the inner wall of the second fixing ring 19 is slidably connected to the outer wall of the fixed shell 13;

[0042] The working principle of the above components: when the transformer 4 needs to be connected to a higher machine through a wiring harness, the wiring harness is passed through the fixing shell 13, so that the wiring harness passes through the water-absorbing sponge 14 and the rubber ring 20. In this way, when it rains, although the rainwater will flow downward along the wiring harness, when the rainwater flows to the water-absorbing sponge 14, the water-absorbing sponge 14 will absorb the rainwater, thereby preventing the rainwater from entering the installation compartment 2. At the same time, because the rubber ring 20 itself has elasticity, after the wiring harness passes through the rubber ring 20, the rubber ring 20 will fit tightly to the wiring harness, thus establishing a second line of defense to further enhance the waterproof effect;

[0043] At the same time, because the amount of water that the water-absorbing sponge 14 can absorb is limited, in order to continuously absorb rainwater, the electromagnet 18 can be started. Here, the fixed column 16 is made of metal. When the electromagnet 18 is started, the fixed column 16 will be attracted to move toward the electromagnet 18, so that the moving ring 15 moves, so that the moving ring 15 squeezes the water-absorbing sponge 14 to squeeze out the water in the water-absorbing sponge 14. At this time, the water will flow from the opening 21 to the rotating shell 12 for storage;

[0044] Taking into account the placement position and angle of the wire harness, the moving block 10 and the rotating block 11 enable the rotating shell 12 to rotate and move laterally.

[0045] The outer ring of the electromagnet 18 is sleeved with a first fixing ring 17, and the outer walls of the first fixing ring 17 and the second fixing ring 19 are both provided with an adjusting device, which includes: a connecting pipe 22, a tapered pipe 23, and a first bolt 24, and the adjusting device is used to adjust the position of the electromagnet 18;

[0046] The outer walls of the connecting tube 22 are fixedly connected to the outer walls of the inner ring of the second fixing ring 19 on both sides, and the outer walls of the fixing shell 13 on both sides are provided with sliding grooves to slide with the outer walls of the connecting tube 22 on both sides, and the outer wall of one side of the tapered tube 23 is fixedly connected to the outer wall of the connecting tube 22 on both sides away from the water-absorbing sponge 14. The outer walls of the connecting tube 22 on both sides are fixedly connected to the outer walls of the inner ring of the second fixing ring 19 on both sides, and the outer walls of the fixing shell 13 on both sides are provided with sliding grooves to slide with the outer walls of the connecting tube 22 on both sides, and the outer wall of one side of the tapered tube 23 is fixedly connected to the outer wall of the connecting tube 22 on one side away from the water-absorbing sponge 14. There are two first bolts 24, and the outer walls of the two first bolts 24 are fixedly connected to the outer walls of the first fixing ring 17 on both sides, and the outer walls of the rotating shell 12 on both sides are slidably connected to the outer walls of the first fixing ring 17 on both sides by providing sliding grooves, and the outer wall of the rotating shell 12 on one side away from the water-absorbing sponge 14 is slidably connected to the outer walls of the two first bolts 24, and nuts are provided at the connection between the rotating shell 12 and the first bolts 24;

[0047] The working principle of the above components: Sometimes when the wire harness is rolled up, there will be water drops on the wire harness. At this time, the above components can be used to remove the water drops on the wire harness. After the wire harness passes through the rotating shell 12, the nut needs to be rotated to move the first bolt 24 away from the water-absorbing sponge 14 to drive the first fixing ring 17 to move away from the water-absorbing sponge 14. At this time, the connecting tube 22 and the tapered tube 23 will squeeze the rubber ring 20, so that the rubber ring 20 is stretched open, so that the wire harness cannot contact the rubber ring 20. When the wire harness passes through the rubber ring 20, the resistance becomes smaller, thereby preventing the rubber ring 20 from rubbing against the wire harness and causing the surface temperature of the wire harness to be too high, and also protecting the shape of the rubber ring 20 from being torn.

[0048] A fixed tube 25 is fixedly installed on the outer wall of one side of the moving ring 15 away from the water-absorbing sponge 14, and a connecting cloth 26 is fixedly installed on the outer wall of the fixed tube 25 away from the moving ring 15. The outer wall of the connecting cloth 26 is connected to a cleaning device, which includes: a metal ring 27, a connecting line 28, two rotating shafts 29, a second fixing frame 30, two gears 31, a handle 32, and a second bolt 33. The cleaning device is used to clean the sludge on the wiring harness;

[0049] The outer wall of the inner ring of the metal ring 27 is fixedly connected to the outer wall of the side of the connecting cloth 26 away from the fixed tube 25, the connecting wire 28 is wound around the outer wall of the metal ring 27, and the outer walls at both ends of the connecting wire 28 are slidably connected to the inner wall of the top of the fixed tube 25, the outer wall of the bottom of the second fixing frame 30 is fixedly connected to the outer wall of the top of the fixed tube 25, the two sides of the top of the second fixing frame 30 are respectively rotatably connected to the outer walls of the two rotating shafts 29, the two ends of the connecting wire 28 are respectively wound around the outer walls of the two rotating shafts 29, the inner walls of the two gears 31 are respectively fixedly connected to the outer walls of one side of the two rotating shafts 29, the two gears 31 are meshed with each other, the handle 32 is fixedly connected to the outer wall of one side of one of the rotating shafts 29, the second bolt 33 is threadedly connected to the outer wall of the top of the second fixing frame 30 away from the moving ring 15, the metal ring 27 is annular in shape, but the metal ring 27 is not closed as a whole, and the second bolt 33 is located above the two gears 31;

[0050] The working principle of the above components: Sometimes when the wire harness is rolled up, there will be mud on the wire harness. At this time, it is necessary to rotate the second bolt 33 upwards so that the two gears 31 can rotate. At this time, the handle 32 is rotated to drive the rotating shaft 29 to rotate, so as to reel in the connecting wire 28. At this time, the connecting wire 28 will squeeze the metal ring 27. Because the metal ring 27 is made of elastic metal material, and the two ends of the metal ring 27 are not closed and staggered, the metal ring 27 will shrink when squeezed, and the metal ring 27 will drive one end of the connecting cloth 26 to shrink. The handle 32 is continuously rotated so that the metal ring 27 drives one end of the connecting cloth 26 to contact the surface of the wire harness. At this time, when the wire harness passes through the metal ring 27, the mud on its surface will be scraped off;

[0051] It should be noted here that the connecting cloth 26 needs to be made of cloth with a certain elasticity, so that when the metal ring 27 rebounds to its original position without being squeezed, the connecting cloth 26 can rebound to its original position, so as not to block the advancement of the wiring harness.

[0052] A drain pipe 34 is fixedly installed at the bottom of the rotating shell 12, and the drain pipe 34 is connected to the inner wall of the rotating shell 12. A threaded connection pipe 35 is fixedly installed at the bottom of the drain pipe 34, and the inner wall of the threaded connection pipe 35 is connected to the drain pipe 34. The outer wall of the threaded connection pipe 35 is threadedly connected to a collecting bottle 36;

[0053] The working principle of the above components: In order to prevent rainwater from scattering into the installation bin 2 when being discharged, a collection bottle 36 can be connected to the threaded connecting pipe 35, so that when the rainwater flows to the drain pipe 34, the rainwater will eventually fall into the collection bottle 36.

[0054] Working principle: When the transformer 4 needs to be connected to a higher machine through a wiring harness, the wiring harness is passed through the fixed shell 13, so that the wiring harness passes through the water-absorbing sponge 14 and the rubber ring 20, so that when it rains, the water-absorbing sponge 14 will absorb the rainwater on the wiring harness. When it is necessary to discharge the rainwater in the water-absorbing sponge 14, the electromagnet 18 is started to attract the fixed column 16 to move toward the electromagnet 18, thereby driving the moving ring 15 to move, so that the moving ring 15 squeezes the water-absorbing sponge 14 to squeeze out the water in the water-absorbing sponge 14, and the water will flow from the opening 21 to the drain pipe 34 under the rotating shell 12, and finally flow into the collection bottle 36. When the wiring harness is retracted, it is necessary to use When the water-absorbing sponge 14 is used to clean the water droplets and sludge on the wiring harness, the nut is rotated to move the first bolt 24 away from the water-absorbing sponge 14 to drive the first fixing ring 17 to move away from the water-absorbing sponge 14. At this time, the connecting tube 22 and the tapered tube 23 will squeeze the rubber ring 20 to open the rubber ring 20. Then, the second bolt 33 is rotated upward, and the handle 32 is rotated to drive the rotating shaft 29 to rotate to reel in the connecting wire 28 to squeeze the metal ring 27, so that the metal ring 27 will drive one end of the connecting cloth 26 to shrink and contact the surface of the wiring harness. In this way, when the wiring harness is pulled through the fixing shell 13, the water droplets and sludge on the wiring harness can be continuously cleaned.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
