Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a power box for power engineering. Background Technology

[0002] In power engineering, the power box is a box-like device used to install and protect various electrical components and cables in the power system, and to realize the functions of power distribution, control and protection. It is an important part of the power transmission and distribution process.

[0003] Existing electrical boxes mainly include floor-standing electrical boxes and wall-mounted electrical boxes. Wall-mounted electrical boxes have a mounting plate on the box body, which, together with screws, allows the electrical box to be installed on the wall. However, in this type of electrical box, the mounting plate is usually welded to the box body. The mounting plate cannot be fitted at different heights or rotated for adjustment. During installation, it cannot be well adapted to the screws or holes on the wall, resulting in poor installation adaptability. Furthermore, there is no buffer structure in the electrical box. Every time the box door is closed, there is a large impact force between the box door and the box body, which can easily cause damage to the box door or the box body, thus affecting the normal use of the electrical box.

[0004] The existing patent (publication number: CN222127400U) discloses an electrical box for power engineering. Through its installation structure, an adjustment groove is set on the fixed frame, which works in conjunction with a mounting plate and a round rod. When needed, the mounting plate can be moved along the adjustment groove, improving installation flexibility. The mounting plate can also be rotated and adjusted via the round rod, making the electrical box highly adaptable to different installations. An internal buffer structure is incorporated into the box, utilizing springs and rubber blocks in the buffer assembly to cushion the impact and prevent direct impact to the box body during door closure. This prevents damage to the door and box body from excessive impact force, ensuring the integrity of the electrical box. The rubber blocks can deform through deformation holes, working in conjunction with the springs to create secondary deformation, further enhancing the buffering effect.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, while the mounting plates proposed in these patents can be adjusted in position and rotation, when adjusting the power distribution box to a horizontal position, it is necessary to coordinate the adjustment of all four mounting plates to easily find the horizontal position. Since most power distribution boxes are large in size and have a certain weight, and there is a certain distance between adjacent mounting plates, it is inconvenient to adjust the horizontal position of the power distribution box, thus affecting the installation efficiency of the power distribution box.

[0006] Therefore, a power box for power engineering is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a power box for power engineering, which can solve the problem that although the mounting plates in the existing patent can be adjusted in position and rotation, when adjusting the power box to a horizontal position, it is necessary to adjust the four mounting plates in a coordinated manner to find the horizontal position. Since most power boxes are large in size and have a certain weight, and there is a certain distance between adjacent mounting plates, it is inconvenient to adjust the horizontal position of the power box, which affects the installation efficiency of the power box.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a power box for power engineering, comprising a power box body, a box door and a heat dissipation vent, wherein a plurality of heat dissipation fins are provided on the rear side of the power box body, and a horizontal adjustment mechanism is provided on the top of the rear side of the power box body;

[0009] The horizontal adjustment mechanism includes two mounting brackets, a mounting plate, a rotating shaft, a rotating plate, and two mounting blocks.

[0010] Preferably, brackets are fixedly connected to both sides of the bottom rear side of the power box body, and the rear side of the brackets and the rear side of the mounting bracket are located on the same plane.

[0011] Preferably, the bottom of the mounting plate has a chamfer on the front side, and handles are fixedly connected to both sides of the power box body.

[0012] Preferably, a bubble level is fixedly connected to the bottom of the front side of the box door.

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

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A power box for power engineering includes a power box body 1, a box door 2 and a heat dissipation vent 7. Several heat dissipation fins 5 are provided on the rear side of the power box body 1, and a horizontal adjustment mechanism 6 is provided on the top of the rear side of the power box body 1.

[0030] The horizontal adjustment mechanism 6 includes two mounting brackets 601, a mounting plate 602, a rotating shaft 603, a rotating plate 604, and two mounting blocks 605. The front side of the mounting bracket 601 is fixedly connected to the rear side of the mounting plate 602, the front side of the mounting block 605 is fixedly connected to the rear side of the rotating plate 604, the mounting block 605 is hung on the surface of the mounting plate 602, the rotating shaft 603 is rotatably connected to the inside of the rotating plate 604, and the front side of the rotating shaft 603 is fixedly connected to the rear side of the power box body 1.

[0031] In this embodiment: First, external bolts are used to fix the mounting plate 602 through the mounting bracket 601. Then, the power box body 1 is moved by holding the handle 11 so that the mounting block 605 is attached to the mounting plate 602. Utilizing the rotational connection between the rotating shaft 603 and the rotating plate 604, as well as gravity, the power box body 1 automatically rotates to a horizontal position. After confirmation by the bubble level 3, an external electric drilling tool is used to drill holes in the wall at corresponding positions through the bracket 4. External expansion bolts are then used to fix the bracket 4, the rotating shaft 603, and the two brackets 4. The three-point support ensures a stable installation, solving the problem of inconsistent leveling of multiple mounting plates in the prior art. This design addresses the issue of convenience and improves installation efficiency. During use, the curved design of the speaker cover 901 on the bottom wiring mechanism 9 prevents excessive bending of the wires. The silicone ring 902 is waterproof and dustproof. Heat inside the power box body 1 is conducted to the heat conduction plate 12 and then quickly dissipated through the aluminum heat sink 5, enhancing the heat dissipation effect. The heat conduction plate 12 is fixed by the plug-in rail 8 and the connecting button 14, allowing it to be reassembled after the box is installed, thus avoiding scratches and damage during the installation of the power box body 1. It should be noted that the layout of electrical components, circuit connections, heat dissipation system, and the connection of the box door 2 inside the power box body 1 are all existing and published mature technologies, which will not be elaborated here.

[0032] Specifically, such as Figure 2As shown, brackets 4 are fixedly connected to both sides of the bottom rear side of the power box body 1, and the rear side of the brackets 4 and the rear side of the mounting bracket 601 are on the same plane.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, a chamfer is provided on the front side of the bottom of the mounting plate 602, and handles 11 are fixedly connected to both sides of the power box body 1.

[0034] Specifically, such as Figure 1 and Figure 6 As shown, a bubble level 3 is fixedly connected to the bottom of the front side of the box door 2.

[0035] In this embodiment: the two brackets 4 at the bottom rear side of the power box body 1 are flush with the rear side of the mounting bracket 601, and together with the rotating shaft 603, they form a stable three-point connection structure. During installation, they are fixed with expansion bolts to enhance the stability of the power box body 1. The bottom chamfer design of the hanging plate 602 makes it easy for the hanging block 605 to be quickly inserted. The handle 11 makes it easy to move the power box body 1. The bubble level 3 can intuitively display the horizontal state of the power box body 1 and assist in precise leveling.

[0036] Specifically, such as Figure 4 As shown, a wiring mechanism 9 is provided at the bottom of the power box body 1. The wiring mechanism 9 includes a speaker cover 901, a silicone ring 902 and a wiring hole 903. The wiring hole 903 is opened at the bottom of the power box body 1. The surface of the silicone ring 902 is fixedly connected to the inner wall of the speaker cover 901. The top of the speaker cover 901 is fixedly connected to the bottom of the wiring hole 903.

[0037] Specifically, such as Figure 5 As shown, a heat-conducting plate 12 is provided on the rear side of the power box body 1, and the front side of the heat sink 5 is fixedly connected to the rear side of the heat-conducting plate 12. Both the heat sink 5 and the heat-conducting plate 12 are made of aluminum.

[0038] In this embodiment: In the wiring mechanism 9, the arc-shaped structure of the speaker cover 901 effectively guides the wires and prevents excessive bending damage. The silicone ring 902 fits tightly against the wires to achieve waterproof and dustproof protection. The heat-conducting plate 12 is combined with the aluminum heat sink 5, which quickly conducts heat due to its excellent thermal conductivity. The heat sink 5 expands the heat dissipation area and significantly improves the heat dissipation efficiency.

[0039] Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, the top and bottom of the rear side of the power box body 1 are fixedly connected to the insertion rails 8, and the heat conduction plate 12 is movably inserted into the inside of the insertion rails 8. The front side of the heat conduction plate 12 is in contact with the rear side of the power box body 1.

[0040] Specifically, such as Figure 1 , Figure 2and Figure 5 As shown, a connecting block 13 is fixedly connected to the left side of the heat-conducting plate 12, and a connecting button 14 is provided on the left side of the connecting block 13. A connecting plate 10 is fixedly connected to the left side of the power box body 1. The right side of the connecting button 14 passes through the connecting block 13 and is threadedly connected to the inside of the connecting plate 10.

[0041] In this embodiment: the plug-in rail 8 provides precise positioning and convenient disassembly and assembly for the heat conduction plate 12. After the power box body 1 is installed, the heat conduction plate 12 and heat sink 5 are installed to avoid damage to the heat sink 5 when installing the power box body 1. The connecting block 13 is limited by the threaded connection between the connecting button 14 and the connecting plate 10 to ensure that the heat conduction plate 12 fits in close with the power box body 1, ensuring heat conduction efficiency and facilitating heat dissipation.

[0042] Working principle: When installing the power box body 1, first use external bolts to pass through the mounting bracket 601 to fix the mounting plate 602 to the wall where it is to be installed, completing the foundation fixation. Then, the operator holds the handles 11 on both sides of the power box body 1 and moves the power box body 1 to the mounting block 605 to hang it on the surface of the mounting plate 602. Since the rotating shaft 603 is rotatably connected inside the rotating plate 604, and the front side of the rotating shaft 603 is fixed to the rear side of the power box body 1, the power box body 1 will automatically rotate around the rotating shaft 603 under the action of gravity until it is in a horizontal state. At this time, the operator observes through the bubble level 3 at the bottom front side of the box door 2 to confirm whether the power box body 1 is completely horizontal. If it is not horizontal, the position can be finely adjusted. If it is horizontal, the position can be adjusted. To ensure the electrical box is level, an external electric drilling tool is used to drill holes in the wall at the corresponding positions, passing through bracket 4. Then, external expansion bolts are used to fix bracket 4 in place. Connecting the pivot point 603 to the two bracket 4 connection points ensures the electrical box body 1 is securely installed. The electrical box body 1 automatically rotates to a horizontal position due to gravity, improving the leveling efficiency and thus installation efficiency. This solves the problem in existing patents where, although the mounting plates can be adjusted in position and rotation, adjusting the electrical box to a horizontal position requires coordinated adjustment of all four mounting plates. Since most electrical boxes are large and heavy, adjacent mounting plates... The distance between them makes horizontal adjustment of the power box in power engineering projects inconvenient, affecting the installation efficiency of the power box. During the use of the power box body 1, the bottom wiring mechanism 9 plays a role. The horn cover 901 guides the wires in and out. Its arc design can avoid excessive bending of the wires and reduce the risk of damage caused by excessive bending when wiring outside the power box body 1. The silicone ring 902 fits tightly with the wires, making it waterproof and dustproof. The heat generated by the operation of electrical components inside the power box body 1 is first conducted to the power box body 1, and then to the heat conduction plate 12 on the rear side. Since the heat conduction plate 12 and the heat sink 5 are both made of aluminum, they have good thermal conductivity, and the heat is quickly transferred to the heat sink 5, which increases the heat output. The surface area accelerates heat exchange with the air, achieving efficient heat dissipation. In addition, the heat-conducting plate 12 is movably inserted into the insertion track 8 and fixed to the connecting plate 10 by the threaded connection of the connecting block 13 and the connecting button 14. When installing the power box body 1, the heat-conducting plate 12 and the heat sink 5 can be installed without first installing them. They can be assembled after the power box body 1 is fixed, which effectively avoids scratching and damage to the heat sink 5 during the installation process. It should be noted that the layout of electrical components, circuit connection, heat dissipation system and the connection of the box door 2 inside the power box body 1 are all existing and published mature technologies, which will not be elaborated here. The addition of the heat-conducting plate 12 and the heat sink 5 further enhances the heat dissipation effect and ensures that the power box body 1 maintains a good working condition during long-term operation.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
