[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. By setting up a vertical plate, adjusting components, sleeve, mounting plate, and electric push rod, the vertical plate can drive the main body of the control cabinet to rotate around the pivot during the lifting and lowering process. With the cooperation of measuring and sensing components, the tilt angle of the main body of the control cabinet can be adjusted, so that the main body of the control cabinet can still be set vertically when it is installed on an inclined base. This provides a certain degree of protection for the internal parts of the control cabinet and can also adjust the center of gravity of the control body, which helps to increase the stability of the control cabinet.

[0016] 2. By setting up support components, the paint is placed inside the cavity, and the paint can fall onto the surface of the base through the discharge hole. Those skilled in the art can select the paint as needed, making the connection between the control cabinet body and the base tighter and the installation range of the control cabinet body wider.

[0017] 3. By setting up a scraper, the scraper can scrape the part where the base and the fixture come into contact, removing impurities adhering to the surface of the base. This reduces the impact of impurities on the fixture and can also smooth the paint, making the paint applied more evenly on the surface of the base. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8 The diagram shows a photovoltaic energy storage control cabinet, including a control cabinet body 1. A base 2 is provided below the control cabinet body 1, and the base 2 is inclined. A fixing frame 3 is provided between the control cabinet body 1 and the base 2. The fixing frame 3 is rotatably connected to the control cabinet body 1 via a rotating shaft 4. A measuring element 5 and a sensing element 6 are provided on one side of the control cabinet body 1. The measuring element 5 is rotatably connected to the control cabinet body 1, and the measuring element 5 and the sensing element 6 are in contact. The sensing element 6 is detachably installed on the outside of the control cabinet body 1. A clamping mechanism is provided below the control cabinet body 1. The clamping mechanism includes a horizontal plate 7 and two sets of support members 8. The horizontal plate 7 is fixedly installed inside the fixing frame 3. Both sets of support members 8 are slidably installed below the horizontal plate 7. Two sets of clamps 9 are provided below the support members 8. A moving device is provided between the two sets of clamps 9. A material feeding component is provided inside the support members 8. A leveling component is provided on the adjacent side of the two sets of clamps 9.

[0029] The moving device includes a rotatable shaft 10, a gear 11 is fixedly sleeved on the outside of the shaft 10, and a second rack 14 is slidably mounted on the top of the support 8. The second rack 14 is fixedly connected to the clamp 9, and the second rack 14 and the gear 11 mesh.

[0030] A sliding member 13 is provided above the shaft member 10. The sliding member 13 is connected to the drive assembly and the fixed frame 3. A rack 12 is fixedly installed inside the sliding member 13. The rack 12 meshes with the gear 11.

[0031] The drive assembly includes a mounting plate 29 and an electric push rod 30. The electric push rod 30 is fixedly mounted on the outside of the fixed frame 3. The output end of the electric push rod 30 passes through the fixed frame 3 and extends into the interior of the fixed frame 3. The output end of the electric push rod 30 is fixedly connected to the mounting plate 29. Plates 27 are fixedly mounted on both sides of the mounting plate 29. A guide groove 28 is provided inside the fixed frame 3. Plates 27 and guide grooves 28 are slidably connected. Plates 27 and sliders 13 are slidably connected.

[0032] Specifically, the control cabinet body 1 is placed on top of the base 2. Under the action of the fixing frame 3, the electric push rod 30 is connected to the external power supply. The electric push rod 30 pushes the mounting plate 29 to move inside the fixing frame 3. The mounting plate 29 drives the plate 27 to move inside the guide groove 28. Since the sliding member 13 and the plate 27 are slidably connected, the plate 27 can drive the sliding member 13 to move when it moves.

[0033] During this process, the sliding member 13 drives the first rack 12 to move. Since the first rack 12 meshes with the gear 11, the sliding member 13 can drive the shaft 10 to rotate when it moves. Since the gear 11 meshes with the second rack 14, the gear 11 can drive the second rack 14 to move when it rotates, thereby driving the two sets of clamps 9 to move closer to each other. The clamps 9 clamp the base 2, thereby fixing the control cabinet body 1 on the top of the base 2. Through the above structure, when fixing the control cabinet body 1 on the base 2, it is not necessary for multiple workers to cooperate, which can reduce the workload of the workers, improve the safety of installation, and increase the stability of the control cabinet body 1.

[0034] It should be noted that the shaft 10 and the support 8 are slidably connected. Under the action of the horizontal plate 7, by adjusting the position of the support 8, it can be adapted to bases 2 of different sizes, making it more widely applicable. The shaft 10 and the sliding member 13 are slidably connected. When the support 8 moves along the length of the horizontal plate 7, it can drive the sliding member 13 to move synchronously, so that the first rack 12 and the gear 11 are always meshed.

[0035] A vertical plate 32 is provided on the side of the mounting plate 29 away from the electric push rod 30. The vertical plate 32 is connected to the fixing frame 3 through a lifting structure. A mounting base 31 is rotatably installed on the top of the vertical plate 32. The mounting base 31 is slidably connected to the bottom of the control cabinet body 1.

[0036] The lifting structure includes a sleeve 33 and an adjusting plate 34. The sleeve 33 is slidably sleeved on the end of the mounting plate 29 away from the electric push rod 30. A rod 35 is fixedly inserted inside the sleeve 33. The rod 35 is slidably connected to the mounting plate 29. A second spring 36 is movably sleeved on the outside of the rod 35. The second spring 36 is fixedly connected to the mounting plate 29. One end of the adjusting plate 34 is rotatably connected to the end of the sleeve 33 away from the mounting plate 29. The other end of the adjusting plate 34 is rotatably connected to the bottom of the vertical plate 32.

[0037] Furthermore, when the mounting plate 29 moves, it can slide inside the sleeve 33. At this time, the mounting plate 29 and the rod 35 are slidably connected, and the second spring 36 is deformed under force. When the two sets of clamps 9 clamp the base 2, the second spring 36 is deformed to its maximum extent. At this time, the mounting plate 29 drives the sleeve 33 to move synchronously. The sleeve 33 pushes the adjusting plate 34 to rotate. The adjusting plate 34 pushes the vertical plate 32 to slide upward inside the fixed frame 3. Under the action of the mounting base 31, the vertical plate 32 can push the control cabinet body 1 to rotate around the rotating shaft 4, thereby adjusting the angle of the control cabinet body 1. It should be noted that the base 2 is tilted. When the control cabinet body 1 is installed on the base 2, it is also tilted. Under the action of gravity, the measuring element 5 is always in a vertical state. When the measuring element 5 contacts the sensing element 6, the control cabinet body 1 is in a vertical state, and the vertical plate 32 stops moving, thereby adjusting the installation state of the control cabinet body 1.

[0038] The feeding assembly includes a cavity 20, which is opened inside the support member 8. The support member 8 has discharge holes 21 on both sides. A shielding member 22 is provided inside the cavity 20. The area of ​​the shielding member 22 is larger than the area of ​​the discharge hole 21. Two sets of extrusion plates 23 are slidably inserted inside the cavity 20. The two sets of extrusion plates 23 are connected to the shaft member 10 through a pushing structure.

[0039] The pushing structure includes an adjusting member 24, which is rotatably inserted into the cavity 20. The adjusting member 24 is fixedly connected to the shaft 10. The adjusting member 24 has an elliptical design. A track 25 is provided inside the adjusting member 24. An installation block 26 is slidably inserted into the track 25. The installation block 26 is fixedly connected to the extrusion plate 23.

[0040] Furthermore, the cavity 20 is filled with a coating, which can be a waterproof coating, a rust-removing coating, or an adhesive, etc., which can be selected by those skilled in the art as needed. When the shaft 10 rotates, it drives the adjusting member 24 to rotate synchronously. Since the track 25 and the mounting block 26 are slidably connected, and the adjusting member 24 is elliptical in design, the adjusting member 24 can push the two sets of extrusion plates 23 away from each other when it rotates, thereby extruding the coating inside the cavity 20. The coating breaks the shielding member 22 and flows out from the discharge hole 21. The coating flows onto the surface of the base 2. The shielding member 22 is made of a fragile material, and in this embodiment, a plastic film is used.

[0041] The leveling assembly includes a scraper 15 and a support plate 16. There are two sets of both scraper 15 and support plate 16. The scraper 15 is fixedly installed on the side of the support plate 16 away from the clamp 9. A push plate 17 is rotatably installed on the top of the support plate 16. The end of the push plate 17 away from the support plate 16 is rotatably connected to the clamp 9. An elastic structure is provided between the two sets of support plates 16.

[0042] The elastic structure includes a crossbar 18 and a first spring 19. The crossbar 18 slides through two sets of support plates 16, and the first spring 19 is movably sleeved on the outside of the crossbar 18. The crossbar 18 and the support plates 16 are fixedly connected.

[0043] Specifically, when the two sets of clamps 9 approach each other, they can drive the scraper 15 to move synchronously. In the initial state, the two sets of scrapers 15 are close together. When the scraper 15 contacts the base 2, the clamps 9 push the push plate 17 to rotate. The push plate 17 drives the scraper 15 to move through the support plate 16. At this time, the two sets of support plates 16 are far apart from each other outside the crossbar 18. The first spring 19 is deformed by force. The support plate 16 drives the scraper 15 to move synchronously, which can scrape the surface of the base 2, remove the impurities attached to the surface of the base 2, and make the paint evenly applied to the part of the base 2 and the clamps 9 in contact.

[0044] Working principle: The main body 1 of the control cabinet is placed on top of the base 2. Under the action of the fixed frame 3, the electric push rod 30 is connected to the external power supply. The electric push rod 30 pushes the mounting plate 29 to move inside the fixed frame 3. The mounting plate 29 drives the plate 27 to move inside the guide groove 28. Since the sliding member 13 and the plate 27 are slidably connected, the plate 27 can drive the sliding member 13 to move when it moves.

[0045] During this process, the sliding member 13 drives the first rack 12 to move. Since the first rack 12 meshes with the gear 11, the sliding member 13 can drive the shaft 10 to rotate when it moves. Since the gear 11 meshes with the second rack 14, the gear 11 can drive the second rack 14 to move when it rotates, thereby driving the two sets of clamps 9 to move closer to each other. The clamps 9 clamp the base 2, thereby fixing the control cabinet body 1 above the base 2.

[0046] When the mounting plate 29 moves, it can slide inside the sleeve 33. At this time, the mounting plate 29 and the rod 35 are slidably connected, and the second spring 36 is deformed under force. When the two sets of clamps 9 clamp the base 2, the second spring 36 is deformed to the maximum extent. At this time, the mounting plate 29 drives the sleeve 33 to move synchronously. The sleeve 33 pushes the adjusting plate 34 to rotate. The adjusting plate 34 pushes the vertical plate 32 to slide upward inside the fixed frame 3. Under the action of the mounting seat 31, the vertical plate 32 can push the control cabinet body 1 to rotate around the rotating shaft 4, thereby adjusting the angle of the control cabinet body 1.

[0047] The cavity 20 is filled with a coating, which can be a waterproof coating, a rust-removing coating, or an adhesive, etc. Those skilled in the art can choose according to their needs. When the shaft 10 rotates, it drives the adjusting component 24 to rotate synchronously. Since the track 25 and the mounting block 26 are slidably connected, and the adjusting component 24 is elliptical in design, the adjusting component 24 can push the two sets of extrusion plates 23 away from each other when it rotates, thereby extruding the coating inside the cavity 20. The coating breaks through the shielding component 22 and flows out from the discharge hole 21, and the coating flows onto the surface of the base 2.

[0048] When the two sets of clamps 9 approach each other, they can drive the scraper 15 to move synchronously. In the initial state, the two sets of scrapers 15 are close together. When the scraper 15 contacts the base 2, the clamps 9 push the push plate 17 to rotate. The push plate 17 drives the scraper 15 to move through the support plate 16. At this time, the two sets of support plates 16 are far apart from each other outside the crossbar 18. The first spring 19 is deformed by force. The support plate 16 drives the scraper 15 to move synchronously, which can scrape the surface of the base 2, remove the impurities attached to the surface of the base 2, and make the paint evenly applied to the part of the base 2 and the clamps 9 in contact.
