Description

Technical Field

[0001] The present invention belongs to the field of JP cabinets, and particularly relates to a multi-side-mounted JP cabinet that is convenient for installation. Background Art

[0002] In the construction and maintenance of power systems, JP cabinets (i.e., low-voltage integrated distribution boxes) play a crucial role. They can not only achieve the distribution, control, and protection of electric energy but also ensure the safe and stable operation of the power grid. However, with the continuous optimization of the power grid structure and the in-depth development of intelligent transformation, a series of problems have emerged during the installation of existing JP cabinets, especially in terms of adaptability, installation efficiency, and safety in old power distribution areas and new power grid construction. There is an urgent need for technological innovation to find solutions.

[0003] Firstly, there is the problem of a single cabinet installation direction. In the initial planning stage of old power distribution areas, due to technical and economic constraints, the installation positions of JP cabinets are often not clearly planned, resulting in many challenges during actual deployment. Most current JP cabinet designs usually adopt a single-side installation interface, that is, they can only be hung or fixed from one side of the cabinet. This design greatly limits the installation flexibility of JP cabinets. Especially in scenarios with limited space, complex terrain, or the need for close cooperation with other equipment, the single installation direction often makes it difficult to find a suitable installation position for the JP cabinet, increasing not only the installation difficulty but also the risk of affecting the operation efficiency and safety of the equipment due to improper installation.

[0004] Secondly, there is the problem of excessive cabinet weight. The weight of a standard JP cabinet usually reaches 300 kg, which poses a significant burden on the structural equipment on some overhead poles in power distribution areas. Especially in old power distribution areas, the brackets on overhead poles are often aging and have limited load-bearing capacity. Installing an overly heavy JP cabinet may not only accelerate the aging process of the brackets, increasing the risk of failure, but also have an adverse impact on the stability of the poles, threatening the safe operation of the power grid.

[0005] Thirdly, there is the problem of complex and inefficient cabinet installation. The installation process of traditional JP cabinets usually requires large auxiliary equipment such as cranes or pulleys, especially when the cabinet needs to be lifted to a certain height for installation. This installation method is not only costly but also has high requirements for the on-site operation environment, often requiring a large open area and sufficient working space. In addition, due to the complex installation process, it usually needs to be carried out under a power outage state, and the entire installation process takes a long time, about 3 hours on average, seriously affecting the continuity and reliability of power supply services. More importantly, during the power outage construction period, operators need to be in close contact with adjacent live equipment, posing a high safety risk. A slight mistake may trigger an electric shock accident, posing a serious threat to the lives of construction workers. Summary of the Invention

Therefore, it should not be construed as a limitation to the present invention.

[0039] As Figure 1 shown, a multi-side-mounted JP cabinet that is convenient for installation includes: a cabinet body 1, an electrical installation rack 3, a telescopic mechanism 2, and a plurality of side installation racks 4. A front cabinet door 12 is provided on one side of the cabinet body 1, a rear cabinet door 13 is provided on the other side of the cabinet body 1, ventilation holes 11 are provided on the side wall of the cabinet body 1, and an inlet 14 and an outlet 15 are provided at the upper part of the cabinet body 1;

[0040] As Figure 4 shown, the electrical installation rack 3 is arranged inside the cabinet body 1. The electrical installation rack 3 includes two columns 31, and a plurality of cross beams 32 are connected between the two columns 31. Electrical equipment is installed on the cross beams 32;

[0041] As Figure 1 、 Figure 8 shown, the telescopic mechanism 2 is installed on the top of the cabinet body 1. The telescopic mechanism 2 includes a scissor-type telescopic frame 21. Two feet 22 are provided at the lower part of the scissor-type telescopic frame 21. One of the feet 22 is pivotally connected to a connecting rod at the lower end of the scissor-type telescopic frame 21, and a chute 23 is provided on the other foot 22. A screw rod 26 is rotatably connected to the cabinet body 1, a connecting block 24 is threadedly connected to the screw rod 26, and both ends of the connecting block 24 are fixedly connected with a connecting shaft 25. The end of the connecting shaft 25 is pivotally connected to another connecting rod at the lower end of the scissor-type telescopic frame 21, and the connecting shaft 25 is movably installed in the chute 23; A hanging bracket 27 is provided at the upper end of the scissor-type telescopic frame 21 for connecting with a bench to realize the hanging installation of the JP cabinet;

[0042] As Figure 3 、 Figure 6 shown, a plurality of side installation racks 4 are arranged on the side wall of the cabinet body 1. The side installation rack 4 includes a mounting plate 41 and a main hoop 42 provided on one side of the mounting plate 41. The main hoop 42 is tightened on the electric pole for laterally installing the JP cabinet on the electric pole.

[0043] When the JP cabinet is installed in a hanging manner, remove the side mounting frame 4 from the side wall of the cabinet body 1, and use bolts to block the connection holes on the cabinet body 1 to prevent rainwater from entering the interior of the cabinet body 1; move the JP cabinet to the lower part of the bench, then rotate the screw rod 26 to extend the scissor expansion frame 21, and connect the hanging frame 27 to the bench. Subsequently, flip the screw rod 26 to contract the scissor expansion frame 21 and lift the JP cabinet upward until the scissor expansion frame 21 is fully contracted or the JP cabinet is lifted to the installation position.

[0044] When the bench is aged or its load-bearing capacity is limited, the JP cabinet is installed on the electric pole in a side-mounted manner. Before installing the JP cabinet, first install the side mounting frame 4 on the side wall of the cabinet body 1, remove the other half of the main hoop 42, then clamp the main hoop 42 on one side of the electric pole, extend the scissor expansion frame 21, connect the hanging frame 27 to the bench, and then contract the scissor expansion frame 21 to lift the JP cabinet upward until the JP cabinet is lifted to the installation position. Then, the operator climbs to a height using a ladder or climbing pole footrests to install the other half of the main hoop 42, so that the JP cabinet is side-mounted on the electric pole; after the installation of the JP cabinet is completed, remove the hanging frame 27 from the bench and remove the scissor expansion frame 21 from the top of the cabinet body 1.

[0045] As Figure 2 shown, water collecting troughs 16 are provided on both sides of the upper part of the cabinet body 1, and water guide pipes 17 are connected to both ends of the water collecting troughs 16 for guiding rainwater to the lower part of the JP cabinet on rainy days.

[0046] As Figure 2 shown, the upper cover plate of the cabinet body 1 has a roof-shaped structure that is high in the middle and low on both sides, and the water collecting trough 16 is installed on the lower side of the upper cover plate to facilitate the rapid convergence of rainwater into the interior of the water collecting trough 16.

[0047] As Figure 8 shown, U-shaped frames 28 are movably installed on both sides of the hanging frame 27 for adjusting the width of the hanging frame 27 to adapt to benches of different widths; both ends of the hanging frame 27 are threadedly connected with fastening bolts 29, and one end of each fastening bolt 29 abuts against the side wall of the U-shaped frame 28 for positioning the U-shaped frame 28 after adjustment.

[0048] As Figure 5As shown in the figure, the cross beam 32 includes a fixed beam 321 and a movable beam 322. Both ends of the fixed beam 321 are fixedly installed on the column 31. On one side of the fixed beam 321, there is an upper fixing plate 323, and the upper end face of the upper fixing plate 323 is lower than the upper end face of the fixed beam 321. On one side of the movable beam 322, there is a lower fixing plate 324, and the lower end face of the lower fixing plate 324 is higher than the lower end face of the movable beam 322. The upper fixing plate 323 and the lower fixing plate 324 are connected by a plurality of springs 327. When installing electrical equipment such as air switches and leakage protectors, first, the upper part of the electrical equipment is clamped on the fixed beam 321, then the movable beam 322 is lifted upward by hand, and the lower part of the electrical equipment is clamped on the movable beam 322. After releasing the hand, the movable beam 322 automatically moves downward under the action of the spring 327 to clamp the electrical equipment tightly, improving the installation efficiency of the electrical equipment.

[0049] As Figure 5 shown in the figure, several guide rods 325 are provided at the lower part of the upper fixed beam 321, and several rod sleeves 326 are provided at the upper part of the lower fixing plate 324. The guide rods 325 are inserted into the rod sleeves 326 with a clearance, ensuring the moving track of the movable beam 322 and preventing the fixed beam 321 and the movable beam 322 from being out of the same plane after the movable beam 322 is lifted or reset, which affects the installation effect of the electrical equipment.

[0050] As Figure 7 shown in the figure, an anti-slip ring 43 is provided inside the main hoop 42, and corrugated protrusions are provided on the inner circle of the anti-slip ring 43, increasing the friction between the hoop and the pole and ensuring the stability of the JP cabinet installation.

[0051] As Figure 7 shown in the figure, the cross section of the anti-slip ring 43 is a trapezoidal structure, and the length of the lower base of this cross section is greater than the length of the upper base. The cross section of the main hoop 42 is adapted to the anti-slip ring 43, and there is a gap between the upper end face of the anti-slip ring 43 and the upper end face of the main hoop 42. When installing the main hoop 42, the lower end face of the anti-slip ring 43 is aligned with the lower end face of the main hoop 42. When the JP cabinet accidentally falls downward, the main hoop 42 moves downward. Under the action of the mating surface between the main hoop 42 and the anti-slip ring 43, the main hoop 42 squeezes the anti-slip ring 43 inward, increasing the friction between the anti-slip ring 43 and the pole and preventing the JP cabinet from falling further, enhancing the stability and safety of the JP cabinet after installation.

[0052] As Figure 6 shown in the figure, a reinforcing hoop 44 is provided at the lower part of the main hoop 42, and the reinforcing hoop 44 is fastened to the pole. The two sides of the lower part of the mounting plate 41 are pivotally connected with diagonal braces 45, and the other ends of the diagonal braces 45 are pivotally connected with the reinforcing hoop 44, further enhancing the stability of the JP cabinet installation.

[0053] The above content is only an example and illustration of the structure of the present invention.
