Description

Technical Field

[0001] The utility model relates to the technical field of distribution equipment, and particularly to a distribution device for electric power construction. Background Art

[0002] The distribution board, also known as the distribution cabinet, is a device for concentrating, switching, and distributing electric energy. The distribution cabinet generally consists of a cabinet body, switches (circuit breakers), protection devices, monitoring devices, electric energy meters, and other secondary components. It is installed at power generation stations, substations, and power customers with large electricity consumption, and can achieve the effects of intelligent power consumption monitoring and power distribution. In the prior art, when the entire cabinet body is installed, various components are generally directly installed on the installation beams or installation frames inside the cabinet. Due to the limited internal space of the cabinet body, it is relatively inconvenient to install, maintain, or replace components later. Therefore, improvements are needed.

[0003] Based on the above problems, after retrieval, a kind of intelligent power construction distribution device provided by the patent with the publication number of CN221328327U includes a distribution board composed of a cabinet internal foundation and a cabinet body shell. The cabinet internal foundation includes a main frame for supporting the cabinet body shell and an installation frame for installing components. The installation frame is rotatably arranged inside the main frame. The cabinet body shell includes two side plates, which are respectively detachably connected to both sides of the main frame. Limiting blocks for limiting the installation frame are detachably arranged on the inner sides of the two side plates; by rotatably arranging the installation frame on the main frame, the installation frame can be rotated when installing components onto the installation frame, so that there are no dead corners when installing or replacing components, achieving the improvement of installation convenience in a limited space, and thus solving the problem that the operation of installing components or later maintenance of the distribution board in the prior art is inconvenient due to the limitation of the cabinet body space.

[0004] Based on the above retrieval, combined with the prior art, it is found that although the power construction distribution devices similar to the above - disclosed one in the prior art can disassemble the side plates to facilitate installation and maintenance operations, the disassembly and assembly operations of the side plates are relatively troublesome, resulting in a reduction in operation efficiency. Therefore, a power construction distribution device is proposed to improve the above problems. Summary of the Utility Model

[0005] The purpose of this application is to provide a power construction distribution device to solve the problems raised in the above - mentioned background art.

[0006] To achieve the above purpose, this application provides the following technical solution: A power construction distribution device, including a base:

[0007] Support columns are vertically fixed at the four corners of the upper end of the base. Side plates are hinged to the side ends of the support columns. An installation frame for installing electrical equipment is fixed to the upper end of the base and is located inside the enclosed space;

[0008] A fixing frame is installed between the tops of the four support columns. A driving motor is installed in the middle of the fixing frame. A threaded rod is vertically installed at the output end of the driving motor. A top plate is arranged above the fixing frame. The top plate can completely cover the top surface surrounded by the support columns and the side plates. Guide sliding rods are vertically fixed at the four corners of the lower end of the top plate. A limiting sliding groove for the vertical sliding of the guide sliding rods is arranged at the upper end of the support column. The threaded rod threadedly penetrates through the top plate;

[0009] A linkage mechanism is connected between the threaded rod and the support column. When the threaded rod rotates, it acts on the side plate through the linkage mechanism, causing the side plate to close. The peripheral edges of the top plate are all folded downwards to limit the outer ends of the side plates in the closed state.

[0010] As a further supplement to this solution, a protective sleeve is fixed at the upper end of the top plate, and the protective sleeve covers the outside of the threaded rod.

[0011] As a further supplement to this solution, the linkage mechanism includes a transmission component and a friction wheel. The friction wheel is vertically rotatably installed at the upper end of the support column and is in contact with the top end of the side plate. A groove adapted to the friction wheel is arranged at the inner wall of the edge of the top plate;

[0012] The transmission component is connected between the friction wheel and the threaded rod. When the threaded rod rotates, it drives the friction wheel to rotate through the transmission component. By using the friction force between the friction wheel and the side plate, the side plate is caused to close.

[0013] As a further supplement to this solution, the transmission component includes a first bevel gear, a second bevel gear, a transmission rod, a third bevel gear and a fourth bevel gear;

[0014] The first bevel gear is coaxially fixed on the threaded rod. The fourth bevel gear is coaxially fixed with the friction wheel. The transmission rod is horizontally rotatably installed on the fixing frame. The second bevel gear and the third bevel gear are respectively coaxially fixed at both ends of the transmission rod, and the second bevel gear and the third bevel gear are respectively meshed with the first bevel gear and the fourth bevel gear.

[0015] As a further supplement to this solution, a one-way thread is arranged on the threaded rod. When the driving motor drives the threaded rod to rotate forward, the threaded rod drives the top plate to move upward and drives the side plate to open through the linkage mechanism. When the driving motor drives the threaded rod to rotate reversely, the threaded rod drives the top plate to move downward and drives the side plate to close through the linkage mechanism.

[0016] As a further supplement to this solution, a two-way thread is arranged on the threaded rod. The driving motor always drives the threaded rod to rotate forward. The threaded rod drives the top plate to move up and down reciprocally and drives the side plate to close through the linkage mechanism.

[0017] As a further supplement to this solution, a handle groove is arranged on the outer end face of one side of the side plate far from the end hinged to the support column.

[0018] In summary, the technical effects and advantages of the present utility model are as follows:

[0019] Through the side plates hinged to the support columns, drive motors, threaded rods, and the linkage mechanism connecting the threaded rods and the support columns and acting on the side plates, all four side plates can be opened outwards, facilitating the installation and maintenance operations of internal electrical equipment. After the installation or maintenance operation is completed, the drive motor can be used to drive the threaded rod to rotate. The threaded rod then drives the top plate to close downwards, and through the linkage mechanism, the side plates are closed. The circumferential edge of the top plate that folds downwards is used to limit the outer ends of the side plates in the closed state, realizing the common locking effect on the four side plates, eliminating the need for staff to manually close the side plates one by one, making the installation and maintenance operations more convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment: Refer to Figures 1-5 the power construction distribution device shown in the figure, which includes a base 1. Support columns 2 are vertically fixed at the four corners of the upper end of the base 1. A side plate 3 is hinged to the side end of the support column 2. A handle groove 301 is provided on the outer end face of one side of the side plate 3 away from the end where it is hinged to the support column 2. An installation frame 5 for installing electrical equipment is fixed to the upper end of the base 1, and 5 is located inside the space surrounded by 3 and 2.

[0029] All four side plates 3 can be opened outwards, facilitating the installation and maintenance operations of the internal electrical equipment.

[0030] A fixing frame 6 is installed between the tops of the four support columns 2. A driving motor 10 is installed in the middle of the fixing frame 6. A threaded rod 11 is vertically installed at the output end of the driving motor 10. A top plate 4 is provided above the fixing frame 6. The top plate 4 can completely cover the top surface surrounded by the support columns 2 and the side plates 3. Guide sliding rods 8 are vertically fixed at the four corners of the lower end of the top plate 4. A limiting sliding groove for the vertical sliding of the guide sliding rods 8 is provided at the upper end of the support column 2. The threaded rod 11 threadedly penetrates the top plate 4. The driving motor 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the top plate 4 to move up and down. When the top plate 4 is in the upward opening state, it is convenient for the staff to install and maintain the electrical equipment on the top of the installation frame 5.

[0031] In order to prevent individual side plates 3 from being in an unclosed state after the installation or maintenance operation due to the negligence of the staff, a linkage mechanism 7 is connected between the threaded rod 11 and the support column 2. When the threaded rod 11 rotates, it acts on the side plate 3 through the linkage mechanism 7, causing the side plate 3 to close. There is no need for the staff to manually close the side plates 3 one by one. The peripheral edges of the top plate 4 are all folded downwards to limit the outer ends of the closed side plates 3, realizing the common locking effect on the four side plates 3.

[0032] Based on the cooperative setting of the above structure, when the staff needs to install or repair the electrical equipment inside the cabinet body, they only need to start the driving motor 10. The driving motor 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the top plate 4 to open upward, so that the side plates 3 lose the limit locking function. The staff can open the corresponding side plates 3 according to the actual installation or repair needs to install and repair the electrical equipment. After the operation is completed, start the driving motor 10 again. The driving motor 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the top plate 4 to close downward, and through the linkage mechanism 7, the side plates 3 are closed. The circumferential edge of the top plate 4 that folds downward is used to limit the outer end of the side plates 3 in the closed state, realizing the common locking function of the four side plates 3, without the need for the staff to manually close the side plates 3 one by one, making the installation and repair operations more convenient.

[0033] Wherein, a protective sleeve 9 is fixed to the upper end of the top plate 4, and the protective sleeve 9 covers the outside of the threaded rod 11 to prevent the threaded rod 11 from being exposed to the outside.

[0034] Regarding the linkage mechanism 7, specifically, as Figure 5 shown, the linkage mechanism 7 includes a transmission component and a friction wheel 76. The friction wheel 76 is vertically rotatably installed at the upper end of the support column 2, and the friction wheel 76 is in contact with the top end of the side plate 3. A groove 401 adapted to the friction wheel 76 is provided at the inner wall of the edge of the top plate 4. The transmission component is connected between the friction wheel 76 and the threaded rod 11. When the threaded rod 11 rotates, the friction wheel 76 is driven to rotate through the transmission component. Using the friction force between the friction wheel 76 and the side plate 3, the side plate 3 is closed. The transmission component includes a first bevel gear 71, a second bevel gear 72, a transmission rod 73, a third bevel gear 74 and a fourth bevel gear 75. The first bevel gear 71 is coaxially fixed on the threaded rod 11, the fourth bevel gear 75 is coaxially fixed with the friction wheel 76, the transmission rod 73 is horizontally rotatably installed on the fixed frame 6, and the second bevel gear 72 and the third bevel gear 74 are respectively coaxially fixed at both ends of the transmission rod 73, and the second bevel gear 72 and the third bevel gear 74 are respectively meshed with the first bevel gear 71 and the fourth bevel gear 75.

[0035] It should be further noted that the top surface of the support column 2 can be set to be slightly lower than the top surface of the side plate 3 to prevent the friction wheel 76 from rubbing against the top surface of the support column 2.

[0036] Regarding the threaded rod 11, as one implementation mode of this embodiment, a one-way thread is provided on the threaded rod 11. When the driving motor 10 drives the threaded rod 11 to rotate forward, the threaded rod 11 drives the top plate 4 to move upward, and drives the side plates 3 to open through the linkage mechanism 7. This design method can automatically open all the side plates 3 at the same time, without the need for staff to manually open the side plates 3. When the driving motor 10 drives the threaded rod 11 to rotate in reverse, the threaded rod 11 drives the top plate 4 to move downward, and drives the side plates 3 to close through the linkage mechanism 7, without the need for staff to manually close the side plates 3.

[0037] Regarding the threaded rod 11, as another implementation mode of this embodiment, a two-way thread is provided on the threaded rod 11, that is, a conventional threaded lead screw in the prior art. The driving motor 10 always drives the threaded rod 11 to rotate forward, and the threaded rod 11 drives the top plate 4 to move up and down reciprocally, and drives the side plates 3 to close through the linkage mechanism 7. In this design, during the process of the top plate 4 opening upward, the friction wheel 76 always exerts an inward closing force on the side plates 3. The staff can manually open the corresponding side plates 3 for installation or maintenance operations according to actual needs, avoiding the ineffective occupation of space caused by the synchronous opening of other side plates 3. During the process of the top plate 4 closing downward, the friction wheel 76 exerts an inward closing force on the side plates 3 to close the side plates 3 in the open state, without the need for staff to manually close the side plates 3.

[0038] The working principle of the present utility model: When the staff needs to install or maintain the electrical equipment inside the cabinet, only need to start the driving motor 10. The driving motor 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the top plate 4 to open upward, so that the side plates 3 lose the limit locking function. The staff can open the corresponding side plates 3 according to actual installation or maintenance needs to install and maintain the electrical equipment. After the operation is completed, start the driving motor 10 again. The driving motor 10 drives the threaded rod 11 to rotate, and the threaded rod 11 drives the top plate 4 to close downward, and through the linkage mechanism 7, the side plates 3 are closed. The peripheral edge of the top plate 4 that folds downward is used to limit the outer end of the side plates 3 in the closed state, realizing the common locking function of the four side plates 3, without the need for staff to manually close the side plates 3 one by one, making the installation and maintenance operations more convenient.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
