Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet fixing device. Background Technology

[0002] With the widespread application and continuous development of power systems, the reliability and convenience of the installation and fixing of distribution cabinets, as key equipment for power distribution and control, are becoming increasingly important. However, existing distribution cabinet fixing devices have gradually revealed many problems in practical applications, seriously affecting the installation efficiency, operational stability, and long-term safety of distribution cabinets. In terms of operational convenience, traditional distribution cabinet fixing devices are often complex in design and cumbersome in installation. Many fixing devices require a large number of specialized tools for installation and debugging; for example, tightening some fixing bolts requires wrenches with specific torque, and operation is extremely inconvenient in the narrow installation space of the distribution cabinet. Installers need to spend a lot of time and energy to ensure the correct installation of the fixing devices, which not only increases labor costs but also prolongs the installation cycle of the distribution cabinet, hindering the rapid progress of power projects. Insufficient stability is also a critical issue concerning the safe operation of distribution cabinets. Existing distribution cabinet fixing devices perform poorly in the face of external impacts such as earthquakes and vibrations. Due to unreasonable fixed structure design, such as insufficient number of fixing points, uneven layout, or insufficient connection strength, the distribution cabinet is prone to displacement, shaking, or even tipping over when subjected to external forces. This can not only damage the electrical components inside the distribution cabinet and affect the continuity of power supply, but may also cause safety accidents such as electrical short circuits and fires, posing a serious threat to the safety of people's lives and property.

[0003] Chinese utility model patent CN219247211U discloses a power distribution cabinet fixing device, including a cabinet body, a steel frame for supporting the cabinet body, a cable trench for facilitating cable routing from the cabinet body, hexagonal bolts for fixing the cabinet body, expansion bolts for fixing the steel frame, a concrete foundation for supporting other components, and a ground. This utility model pre-reserves space for steel profiles according to the dimensions of the power distribution cabinet during foundation pouring. The purpose of this utility model is to ensure the stability of the main power distribution cabinet and the reliability and safety of on-site power supply. This fixing device is simple to install and disassemble, allows for the reuse of the power distribution cabinet installation, and achieves high efficiency and reliability in power distribution cabinet installation.

[0004] The above-mentioned device has at least the following technical defects:

[0005] 1. The design of this device is based on the ground and concrete foundation. This structure limits its installation location to ground. In some special application scenarios, such as the middle floor of a high-rise building or in some industrial facilities with special space requirements, the distribution cabinet needs to be installed on the wall or suspended. This device cannot meet the requirements because it does not take into account the compatibility structure of other installation methods, such as the lack of reserved holes for suspension or connectors that can be fixed to the wall.

[0006] 2. Although the device uses hexagonal bolts to fix the cabinet and expansion screws to fix the steel frame, the electrical components installed in the distribution cabinet will vibrate when working, and changes in the external environment will also affect the stability of the distribution cabinet.

[0007] 3. The above-mentioned device fixes the power distribution cabinet on the ground, which is not conducive to the ventilation and heat dissipation of the power distribution cabinet. Especially when the power distribution cabinet is installed in an outdoor environment, the moisture on the ground will easily enter the power distribution cabinet, thereby reducing the service life of the electrical components inside the power distribution cabinet.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1-5 As shown, this utility model provides a power distribution cabinet fixing device, including a power distribution cabinet 1 and a fixing mechanism 4. The fixing mechanism 4 is used to limit the position of the power distribution cabinet 1. The fixing mechanism 4 consists of a fixing plate 11 and positioning plates 16 respectively fixedly connected to the upper and lower ends of the fixing plate 11; a sleeve plate 9, which is sleeved on the outer surface of the fixing plate 11; a lower support plate 2, which is detachably installed on the sleeve plate 9; an upper support plate 3, which is fixed to the top of the fixing plate 11; and an adjustment mechanism, which is installed on the fixing plate 11 and used to adjust the position of the sleeve plate 9. The lower support plate 2 has a groove with a top opening, and the upper support plate 3 has a groove with a bottom opening. The upper and lower ends of the power distribution cabinet 1 are installed in the grooves opened by the lower support plate 2 and the upper support plate 3.

[0028] The upper and lower ends of the surface of the fixed plate 11 away from the upper support plate 3 are respectively fixed with protrusions 12. The center of the outer surface of the two protrusions 12 on opposite sides is rotatably connected with a threaded rod 14. The top end of the threaded rod 14 passes through the protrusion 12 located at the top of the fixed plate 11. The top end of the threaded rod 14 is fixed with a crank handle 13. The outer surface of the sleeve plate 9 is fixed with a connecting block 15 that is threadedly connected to the threaded rod 14.

[0029] Movable triangular blocks 5 are slidably connected to both sides of the inner wall of the groove at the bottom of the lower support plate 2. At least three first guide rods 6 are fixed to the two movable triangular blocks 5 respectively. The first guide rods 6 pass through the side of the lower support plate 2 respectively. The outer surface of the first guide rods 6 is sleeved with a first spring 7. The two ends of the first spring 7 are in contact with the movable triangular block 5 and the inner wall of the lower support plate 2 respectively.

[0030] The top of the upper support plate 3 has four through holes evenly distributed. The inner wall of the through holes is slidably connected to a second guide rod 18. The bottom of the second guide rod 18 is fixedly connected to a moving plate 17. The top of the second guide rod 18 is fixedly connected to a stop block 21. The outer surface of the second guide rod 18 is sleeved with a second spring 19. The upper and lower ends of the second spring 19 are in contact with the upper support plate 3 and the moving plate 17, respectively.

[0031] Two misaligned triangular blocks 20 are fixedly connected to the bottom of the power distribution cabinet 1, and the two misaligned triangular blocks 20 are in contact with the side of the movable triangular block 5 respectively.

[0032] Bolt holes are respectively provided at the upper and lower ends of the outer surface of the positioning plate 16.

[0033] Baffles 10 are fixedly connected to the left and right ends of the outer surface of the sleeve plate 9 away from the adjustment mechanism. The baffles 10 are L-shaped. A connecting plate 8 is fixedly connected to the rear end of the lower support plate 2. A sliding groove is provided between the baffles 10 and the sleeve plate 9. The connecting plate 8 is detachably installed on the inner wall of the sliding groove.

[0034] The working principle of this device is as follows: First, the fixing mechanism 4 (including the fixing plate 11 and the positioning plate 16) is fixed in a suitable position through the bolt holes at both ends of the outer surface of the positioning plate 16, such as on the wall of the building or on a special distribution cabinet mounting bracket. Then, the distribution cabinet is placed in the groove opened on the lower support plate 2, and the height of the lower support plate 2 is adjusted by the adjustment mechanism. The distribution cabinet 1 is fixed in conjunction with the groove opened on the upper support plate 3.

[0035] The working principle of the adjustment mechanism is as follows: turn the crank handle 13, and the crank handle 13 drives the threaded rod 14 to rotate. Since the connecting block 15 on the outer surface of the sleeve plate 9 is threadedly connected to the threaded rod 14, when the threaded rod 14 rotates, the connecting block 15 will carry the sleeve plate 9 up and down along the fixed plate 11 until the distribution cabinet 1 is installed into the groove of the upper support plate 3.

[0036] When installing the distribution cabinet, the bottom of the distribution cabinet 1 needs to be aligned with the groove of the lower support plate 2. When the two misaligned triangular blocks 20 at the bottom of the distribution cabinet 1 contact the movable triangular block 5 in the groove of the lower support plate 2, the movable triangular block 5 will slide on the inner wall of the bottom of the groove as the distribution cabinet 1 is pressed down. The first guide rod 6 on the movable triangular block 5 will compress the first spring 7 as it passes through the side of the lower support plate 2. This design can buffer and initially position the bottom of the distribution cabinet 1, reduce the vibration generated by the operation of electrical components, and reduce the impact of the external environment on electrical components, thereby protecting the electrical components.

[0037] After the bottom of the distribution cabinet 1 is installed in place, continue to lift the distribution cabinet 1 upwards so that its top enters the groove of the bottom opening of the upper support plate 3. During this process, the moving plate 17 at the bottom of the second guide rod 18 in the through hole at the top of the upper support plate 3 will be squeezed upwards by the top of the distribution cabinet 1. The second guide rod 18 slides in the through hole, and at the same time the second spring 19 is compressed. When the distribution cabinet 1 is fully installed in place, the second spring 19 will provide a certain downward pressure, so that the distribution cabinet 1 is stably fixed between the upper and lower support plates in the vertical direction. This design can further increase the stability of the device.

[0038] The distribution cabinet 1 is installed in the grooves of the lower support plate 2 and the upper support plate 3 at its upper and lower ends, respectively. This method of simultaneous fixation at both ends can effectively prevent the distribution cabinet 1 from shaking in the vertical direction. Furthermore, the elastic components (second spring 19 and first spring 7) inside the upper support plate 3 and the lower support plate 2 generate a reaction force when subjected to pressure, which can tightly fit the upper and lower surfaces of the distribution cabinet 1, further enhancing the stability of the fixation.

[0039] The existence of the adjustment mechanism allows the height of the lower support plate 2 to be flexibly adjusted. By turning the rocker handle 13 to change the position of the sleeve plate 9 on the fixed plate 11, the distance between the upper and lower support plates can be adjusted, thereby adapting to distribution cabinets 1 of different heights and expanding the applicability of this device.

[0040] If users find that the installation height of the distribution cabinet 1 needs to be fine-tuned during installation, or if there are issues such as uneven ground or deviations in the mounting brackets, they can quickly and easily make adjustments using the adjustment mechanism, reducing difficulties and errors during the installation process.

[0041] This device is simple to operate, easy to use, and ingeniously structured. It achieves the fixation and protection of the distribution cabinet, reduces the impact of the external environment on the distribution cabinet, and keeps the distribution cabinet away from the ground after installation, which further facilitates heat dissipation of the distribution cabinet. At the same time, it reduces the impact of ground moisture on the electrical components inside the distribution cabinet, thereby extending the service life of the electrical components.

[0042] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
