[0041] As Figures 1 to 4 shown, a buried box-type substation with waterproof and corrosion-resistant functions includes an outer box body 1, a power distribution cabinet 2 and a drainage mechanism. The power distribution cabinet 2 is arranged inside the outer box body 1, and the drainage mechanism is arranged on the outer box body 1. The drainage mechanism includes:

[0042] A first water storage frame 3, sleeved on the outer box body 1, the top of the first water storage frame 3 is flush with the top of the outer box body 1, and a cavity is formed between the first water storage frame 3 and the outer box body 1;

[0043] A water storage tank 4, arranged inside the outer box body 1, and a water inlet 5 is arranged on one side of the water storage tank 4, and the water inlet 5 is communicated with one side of the outer box body 1;

[0044] A heat dissipation component is arranged on the power distribution cabinet 2, and one part of the heat dissipation component communicates with the outer box body 1;

[0045] A water pump 6 is arranged between the power distribution cabinet 2 and the water storage tank 4, and both ends of the water pump 6 are respectively communicated with the water storage tank 4 and the heat dissipation component;

[0046] A pressurization component is arranged in the cavity. The pressurization component is located beside the outer box body 1, and the pressurization component is used to squeeze the water at one end of the cavity to move towards the other end;

[0047] A box lifting component is arranged at the bottom of the cavity. The box lifting component is in transmission connection with the power distribution cabinet 2, and the box lifting component drives the power distribution cabinet 2 to move upward by the power of squeezing the water flow by the pressurization component.

[0048] The water is converged into the cavity through the first water storage frame 3 and flows into the water storage tank 4 through the water inlet 5. The water in the water storage tank 4 is conveyed to the heat dissipation component through the water pump 6. After the heat dissipation component absorbs the heat dissipated by the electrical components inside the power distribution cabinet 2, it flows out of the outer box body 1, so that the buried box substation can drain water in time, prevent water corrosion, and the power distribution cabinet 2 can be cooled in time. By squeezing the water in the cavity through the pressurization component, the water pressure drives the box lifting component to move upward, and the box lifting component drives the power distribution cabinet 2 to move upward, so that the electrical components in the power distribution cabinet 2 will not be damaged by water corrosion caused by water leakage of the outer box body 1, solving the problem of poor waterproof and corrosion resistance of the existing buried box substation, and realizing the problem of effectively draining water and preventing water corrosion of the buried box substation.

[0049] As an optional embodiment, a plurality of first rectangular through holes 7 are arranged at the top of the first water storage frame 3.

[0050] By arranging a plurality of first rectangular through holes 7 on the first water storage frame 3, stone and soil blocks cannot fall into the cavity, solving the problem that stone and soil blocks fall into the cavity, resulting in the blockage of the cavity and affecting the normal operation of the pressurization component, and realizing the problem of protecting the cavity.

[0051] As an optional embodiment, the heat dissipation component includes:

[0052] A second water storage frame 8 is sleeved on the power distribution cabinet 2, and the bottom of the second water storage frame 8 is flush with the power distribution cabinet 2;

[0053] A first water pipe 9, one end of which is communicated with one side of the second water storage frame 8, and the other end of the first water pipe 9 is communicated with the output end of the water pump 6;

[0054] The second water pipe 10, one end of which is communicated with the side of the second water storage frame 8 away from the first water pipe 9, and the other end of the second water pipe 10 penetrates through the outer box body 1.

[0055] The water in the water storage tank 4 is conveyed to the second water storage frame 8 through the first water pipe 9 by the water pump 6. The heat dissipated by the electrical components in the power distribution cabinet 2 is taken away by the flowing water in the second water storage frame 8. The water that absorbs heat is discharged outside the outer box body 1 through the second water pipe 10. Thus, during the drainage and waterproof process of the buried box substation, it also has the purpose of dissipating heat from the power distribution cabinet 2, solves the problem of how to dissipate heat from the power distribution cabinet 2, and realizes the problem of absorbing heat and discharging it from the power distribution cabinet 2 by using the drainage of the buried box substation.

[0056] As an alternative embodiment, the pressurizing assembly includes:

[0057] A threaded rod 11, hinged on one side of the outer box body 1;

[0058] A water pressing plate 12, the center of which is sleeved on the threaded rod 11;

[0059] A first bevel gear 13, sleeved on one end of the threaded rod 11;

[0060] A motor 14, mounted inside the outer box body 1, and the output shaft of the motor 14 penetrates through the outer box body 1;

[0061] A second bevel gear 15, sleeved on the output shaft of the motor 14, and the second bevel gear 15 meshes with the first bevel gear 13.

[0062] The motor 14 drives the second bevel gear 15 to rotate, the second bevel gear 15 drives the first bevel gear 13 to rotate, the first bevel gear 13 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the water pressing plate 12 to move in the cavity, so that the water pressing plate 12 pushes the water in the cavity to drive the lifting box assembly to move upward, solves the problem of how to apply pressure to the water, and realizes the problem of driving the lifting box assembly to move upward by the principle of squeezing the water at one end of the cavity to move to the other end.

[0063] As an alternative embodiment, there is a gap for water to flow into the first water storage frame 3 between a place near the top of the first water storage frame 3 in the cavity and the water pressing plate 12.

[0064] For example, in order to enable the water pressing plate 12 to squeeze water and move within the cavity, one side of the water pressing plate 12 within the cavity is attached to the first water storage frame 3, and the other end is attached to the outer box body 1, thereby achieving the purpose of squeezing water and moving. However, this method causes water to fall on the water pressing plate 12 through the first rectangular through hole 7 and cannot flow into other cavities at the bottom of the water pressing plate 12. By providing a certain gap between a location of the cavity close to the first rectangular through hole 7 and the water pressing plate 12, water falls onto the water pressing plate 12 through the first rectangular through hole 7 and flows into other cavity areas at the bottom of the water pressing plate 12 through the gap, so that the water pressing plate 12 can normally squeeze water and move within the cavity, solving the problem that the water pressing plate 12 encloses the cavity, resulting in water being unable to fall into other cavity areas at the bottom of the water pressing plate 12, and achieving an area within the cavity where the water pressing plate 12 cannot be closed to facilitate water circulation.

[0065] As an alternative embodiment, a water baffle 16 is provided at one end of the cavity away from the threaded rod 11. The water baffle 16 is located at the top of the water inlet 5. A ventilation fan 17 is provided inside the outer box body 1. The ventilation fan 17 is inserted on one side of the outer box body 1 away from the threaded rod 11. A grille 18 is provided on one side of the first water storage frame 3 close to the ventilation fan 17. The grille 18 is located at the top of the water baffle 16.

[0066] The heat inside the outer box body 1 is extracted into the cavity by the ventilation fan 17 and discharged through the grille 18, so that the inside of the outer box body 1 is further cooled. By providing a water baffle 16 at the top of the cavity at the location of the water inlet 5, the water in the cavity will not flow into the inside of the outer box body 1 through the ventilation fan 17, solving the problem of poor air fluidity inside the outer box body 1 and achieving the problem of providing a water-free area within the cavity to facilitate ventilation measures.

[0067] As an alternative embodiment, the lifting box assembly includes:

[0068] A lifting frame 19 is inserted through the bottom of the outer box body 1. The top of the lifting frame 19 is fixedly connected to the power distribution cabinet 2. Second rectangular through holes 20 are provided on both sides of the lifting frame 19 along the water flow direction, and each second rectangular through hole 20 is located at a location of the lifting frame 19 close to the bottom;

[0069] A clamping plate 21 is provided inside the lifting frame 19, and the clamping plate 21 is fixedly connected to the first water storage frame 3;

[0070] A first partition plate 22 is inserted into the clamping plate 21. The top of the first partition plate 22 is fixedly connected to the lifting frame 19, and a third rectangular through hole 23 is provided at a location of the first partition plate 22 close to the first water storage frame 3;

[0071] Two second partition plates 24 are respectively located on one side of the lifting frame 19, and each of the second partition plates 24 is fixedly connected to the first water storage frame 3.

[0072] The water pressure plate 12 sends water pressure into the interior of the lifting frame 19 through the second rectangular through hole 20. Under the sealing action of the clamping plate 21, the first partition plate 22 and the second partition plate 24, the water pressure drives the lifting frame 19 to move upward inside the lifting frame 19. The lifting frame 19 drives the power distribution cabinet 2 to move upward. When the lifting frame 19 rises to the highest position, the other side of the first partition plate 22 is communicated through the third rectangular through hole 23, so that water flows into the water storage tank 4 through the water inlet 5, solving the problem that the power distribution cabinet 2 is corroded and damaged by water, and realizing the problem that the power distribution cabinet 2 is supported inside the outer box body 1 and cannot contact the water at the bottom of the outer box body 1.

[0073] As an alternative embodiment, a limiting block 25 is extended outward at the bottom of the lifting frame 19.

[0074] For example, by arranging the limiting block 25 at the bottom of the lifting frame 19, the lifting frame 19 will not penetrate out of the outer box body 1 during the rising process, solving the problem that the lifting frame 19 penetrates into the interior of the outer box body 1 and causes water to flow into the outer box body 1 and soak the power distribution cabinet 2, and realizing the problem of limiting and protecting the lifting frame 19.
