Description

Technical Field

[0001] The present application relates to the technical field of distribution boxes, and in particular to an intelligent distribution box. Background Art

[0002] Distribution boxes are essential components of power supply and distribution systems. Their proper installation and stable operation are crucial to ensuring reliable power transmission. Outdoor installations, particularly those below a pole-mounted transformer, are common. This installation method efficiently utilizes space and facilitates centralized management and maintenance of the transformer and distribution box. Utility poles typically serve as supporting structures, providing a foundation for the transformer and distribution box, ensuring their stability in complex outdoor environments and meeting the power needs of the surrounding area.

[0003] Currently, a common method for installing outdoor distribution boxes is below a pole-mounted transformer. The installation process involves first securing two horizontal crossarms side by side on two utility poles to provide a support platform for subsequent equipment installation. Next, the oil-immersed transformer is mounted above the two crossarms using screws or welding to secure them firmly in place. Finally, the top side of the distribution box is screwed to the bottom of the crossarms, completing the installation. This installation technique is widely used in the power industry and offers a certain degree of stability and practicality.

[0004] However, when screwing the distribution box to the bottom of the crossarm, it's necessary to use a lifting device (such as an electric forklift) to continuously support the box to align the through-holes on the upper side of the box with the screw holes on the crossarm. However, distribution boxes are often installed close to the road, and the vibrations from frequent roadside trucks can easily cause the lifting device to shift slightly. This shift can cause the previously aligned through-holes and screw holes to become misaligned again, forcing installers to spend a considerable amount of time repeatedly re-aligning them. This significantly reduces installation efficiency and increases both construction costs and time. Improvements are urgently needed. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent distribution box to solve the problem of low efficiency when the distribution box is installed below the pole-mounted transformer in the above-mentioned related art.

[0006] The intelligent distribution box provided in this application adopts the following technical solution: An intelligent distribution box comprises a box body and a top cover fixedly mounted on the top of the box body, an installation cavity is provided on a vertical surface of one side of the box body, and a box door for sealing the installation cavity is detachably mounted thereon, a plurality of heat dissipation openings are provided on two opposite vertical side surfaces of the box body, and protective covers with downward openings are fixedly mounted on the opening edges of the heat dissipation openings; vertically upward fixing rods are mounted on two opposite side surfaces of the top cover, and the surfaces of the fixing rods are perpendicular to the surfaces of the heat dissipation openings; a positioning rod is horizontally mounted above the top cover with one end rotatably connected to the upper end surface of the fixing rod, and the rotating surface of the positioning rod is parallel to the upper surface of the top cover.

[0007] By adopting the above technical solution, when installing the distribution box, the positioning rod is pre-rotated from the top of the top cover. After the distribution box is moved to the bottom of the transformer on the pole using the lifting equipment, the positioning rod is rotated back to the top of the top cover. At this time, the cross arm on the pole is located between the positioning rod and the top cover. In this way, the distribution box is auxiliary supported by the fixing rod and the positioning rod, and is conveniently positioned and coordinated with the cross arm and other structures. There is no need to rely entirely on the lifting equipment to accurately lift the distribution box to align the hole positions as in the traditional way. Even if the vibration caused by the passing of a large truck on the roadside causes the lifting equipment to shift, the positioning rod can maintain the relative position to a certain extent, reducing the occurrence of misalignment between the through hole and the screw hole. This effectively avoids the installer from repeatedly performing alignment operations, greatly saves installation time, significantly improves installation efficiency, and thus reduces construction costs and time costs, and effectively solves the problem of low distribution box installation efficiency in the existing technology.

[0008] Optionally, a receiving notch is provided on the upper side surface of the top cover; the lower end of the fixing rod is rotatably connected to the vertical side of the top cover, and the rotating surface of the fixing rod is parallel to the vertical side surface of the connected top cover; the positioning rod can be rotated into the receiving notch when the fixing rod is rotated downward to a horizontal state, and the upper side surface of the positioning rod is now flush with the upper surface of the top cover.

[0009] By adopting this technical solution, the positioning rod and fixing rod can be cleverly stored during non-installation periods or during transportation, eliminating extra space and preventing them from protruding and causing accidental damage such as scratches, thereby improving safety. This also makes the distribution box more regular and aesthetically pleasing. During installation, the positioning rod can be quickly deployed for positioning, balancing installation convenience with practicality for daily use.

[0010] Optionally, two traction rods are provided in the vertical direction on the vertical outer side of the box body with a heat dissipation outlet, and a sealing plate is provided under the protective cover, and both ends of several sealing plates are fixedly connected to the side surfaces of the two traction rods close to each other; an elastic clip is provided on the side of the traction rod facing the box body, and several positioning grooves are provided on the outer side of the box body, and the elastic clip is inserted into the corresponding positioning groove when the traction rod slides up and down; the traction rod can drive the sealing plate to move up to block the lower opening of the protective cover, and move down to release the blockage of the protective cover opening.

[0011] By adopting this technical solution, a traction rod and a blocking plate are installed on the vertical outer side of the heat dissipation vent of the box, allowing the opening below the protective cover to be opened and closed as needed. Through the coordination of elastic clips and positioning grooves, the traction rod can be stably positioned at different positions, driving the blocking plate to precisely move upward to block the opening, preventing rainwater and debris from entering the box and ensuring the safety of the internal equipment. When moved downward, the blockage can be released to ensure normal heat dissipation. This design can be flexibly adjusted according to actual weather conditions and heat dissipation requirements, balancing the protection performance and heat dissipation function of the distribution box, effectively improving the adaptability and operational stability of the distribution box in different environments.

[0012] Optionally, an insulating pull rod is provided on the outside of the box body, and both ends of the insulating pull rod are fixedly connected to the ends of the two traction rods away from the top cover.

[0013] By adopting this technical solution, when the drawbar needs to be slid up and down to control the blocking plate to block and release the shield opening, the installer can directly operate the insulating pull rod. The insulating material effectively prevents electric shock during operation, ensuring operational safety.

[0014] Optionally, a movable wheel is fixed on the side away from the top cover when the positioning rod is inside the receiving gap. When the distribution box needs to be moved, the top cover can be flipped to a moving state facing the ground. At this time, the movable wheel can abut against the ground when the positioning rod is in the receiving gap.

[0015] By adopting this technical solution, when the distribution box needs to be moved, the top cover can be flipped to a ground-facing position, at which point the wheels can contact the ground. This eliminates the need for additional tools or multiple people to move the distribution box during transport or repositioning, allowing installers to easily push and move it, significantly saving labor costs and improving movement efficiency.

[0016] Optionally, a limit shaft is fixed on the outer periphery of the end parts of the two traction rods close to the top cover, and two opposite limit blocks are fixed on the vertical outer side of the box body; a limit slide groove for inserting and sliding the limit shaft is opened in the vertical direction on the side surfaces of the two limit blocks close to each other, and the traction rod can rotate around the axis of the limit shaft; a control member for limiting the rotation of the traction rod is provided on the box body, and the control member releases the rotation limit of the traction rod when the positioning rod rotates into the storage notch, and limits the rotation of the traction rod when it rotates out of the storage notch; when the top cover of the movable wheel is facing the ground and the movable wheel itself can abut against the ground, the traction rod can be rotated in the direction away from the box body to an inclined state to pull the box body to slide.

[0017] By adopting the above technical solution, the control component design is very clever. When the positioning rod is rotated into the storage notch, the rotation limit on the traction rod is released, facilitating subsequent operation; when it is rotated out, it is limited to ensure structural stability. When the top cover is facing the ground and the moving wheel is in contact with the ground, the traction rod can be rotated to an inclined state away from the box body to pull the box body and slide. This makes the movement of the distribution box more labor-saving and the direction easier to control. Overall, the coordinated action of these components not only ensures the stability and precision of the traction rod when adjusting the sealing plate, but also gives the distribution box better controllability and convenience when moving, improving the adaptability and practicality of the product in different usage scenarios and reducing the difficulty and labor intensity of operation.

[0018] Optionally, the control member includes a locking plate rotatably arranged on the inner wall of the box, an adjusting member for controlling the rotation of the locking plate, and a control strip fixed on the side of the traction rod facing the box, and a guide groove is provided on the box in the vertical direction for the control strip to be inserted and slide up and down; the rotating surface of the locking plate is parallel to the inner wall of the box to which it is connected, and a control notch is provided on the vertical side of the control strip close to the locking plate, and the adjusting member can drive the edge of the locking plate to rotate in or out of the control notch.

[0019] By adopting the above technical solution, when the positioning rod rotates into the storage notch and the traction rod rotation limit needs to be released, the adjustment member drives the edge of the locking plate to rotate out of the control notch, allowing the traction rod to rotate freely and flexibly. When the positioning rod rotates out of the storage notch, the edge of the locking plate rotates into the control notch, effectively limiting the rotation of the traction rod and ensuring structural stability. At the same time, the control strip slides up and down within the guide groove to ensure the linearity and stability of the traction rod movement and avoid deviation. This solution integrates the control function inside the box, has a compact structure, does not occupy external space, does not affect the overall appearance and protective performance of the distribution box, and is easy to operate. The traction rod rotation limit can be switched simply by adjusting the member, greatly improving the convenience and safety of the distribution box during installation, movement, and other operations.

[0020] Optionally, the adjusting member includes an elastic return member, an adjusting rod slidingly arranged on the inner wall of the box in a vertical direction, and a torsion spring arranged on the locking plate; the torsion spring is used to drive the locking plate to rotate into the control notch in the direction close to the control insertion strip, and an adjusting through-hole for the end of the adjusting rod to pass through is provided on the bottom surface of the receiving notch, and a control rod is fixedly fixed at an end of the adjusting rod away from the top cover at an angle; the elastic return member is used to drive the adjusting rod to slide in the direction close to the top cover until it protrudes from the adjusting through-hole; when the positioning rod rotates into the receiving notch, the protruding part of the adjusting rod is squeezed, and the locking plate then abuts and slides along the inclined surface on the control rod, so that the locking plate rotates out of the control notch in the direction away from the control insertion strip.

[0021] By adopting the above technical solution, the elastic reset member is used to keep the adjustment rod in a protruding state, and the torsion spring is used to allow the locking plate to naturally rotate into the control notch to achieve positioning, which has a simple and reliable structure. When the positioning rod rotates into the storage notch, the adjustment rod is squeezed, and the locking plate is rotated out of the control notch through the inclined surface of the control rod. The mechanical linkage is cleverly used to achieve automatic unlocking, without the need for additional manual operation, which improves the convenience and efficiency of operation. At the same time, the various components work together, and when the positioning rod is rotated out, the elastic reset member and the torsion spring can quickly restore the positioning state to ensure structural stability. This design not only reduces the errors and operational difficulties that may be caused by manual intervention, but also makes the entire positioning control process smooth and natural, effectively improving the accuracy and safety of the distribution box operation under different working conditions, and reducing maintenance costs and usage risks.

[0022] Optionally, a limiting rod parallel to the adjusting rod is fixed to the end of the control rod away from the adjusting rod, and the edge of the locking plate abuts against one side of the limiting rod when it rotates into the control notch.

[0023] By adopting this technical solution, when the edge of the locking plate rotates into the control notch, it abuts against one side of the limit rod, providing a clear physical limit to the locking plate's rotation range. This effectively prevents the locking plate from overrotating, avoiding structural damage or control failure caused by excessive rotation, and enhances the stability and reliability of the entire control structure.

[0024] Optionally, the elastic return member includes a spring in a compressed state, a guide block fixed on the inner wall of the box, and a baffle fixed on the outer periphery of the adjusting rod, the guide block is provided with a guide hole for the adjusting rod to pass through, the guide block is located below the baffle, and the two ends of the spring are respectively fixedly connected to the side surfaces of the guide block and the baffle close to each other.

[0025] By adopting this technical solution, the compressed spring provides a stable elastic force, ensuring that the adjustment rod always tends to slide toward the top cover. This ensures that the adjustment rod is in its initial state of protruding from the adjustment hole when there is no external interference, allowing the entire limit control mechanism to be reliably reset. The combination of the guide block and the guide hole provides precise guidance for the sliding of the adjustment rod, preventing offset and jamming during movement, and ensuring smooth and stable movement. The baffle setting clarifies the spring's installation position and range of action, allowing the spring's elastic force to effectively act on the adjustment rod.

[0026] In summary, this application has the following beneficial technical effects: The distribution box easily aligns with crossarms and other structures, eliminating the need for traditional lifting equipment to precisely align the distribution box holes. Even if the vibrations of a passing truck cause the lifting equipment to shift, the positioning rods maintain relative position to a certain extent, reducing the possibility of misalignment between the through-holes and screw holes.

The traction rod 41 is provided with a placement groove 411 for the compression spring 431 and the arc-shaped protrusion 432 to be placed. The compression spring 431 presses one side of the arc-shaped protrusion 432, causing a portion of the arc-shaped protrusion 432 to protrude from the opening of the placement groove 411. The outer side surface of the protruding portion of the arc-shaped protrusion 432 is an arc surface, and the arc length corresponding to the arc surface is the minor arc. An insulating pull rod 44 is provided on the outside of the box body 1, and both ends of the insulating pull rod 44 are fixedly connected to the ends of the two traction rods 41 away from the top cover 11; when the staff drives the traction rod 41 up and down, they can operate more safely through the insulating pull rod 44, reducing safety hazards during operation.

[0036] Reference Figure 5 and Figure 6 When the positioning rod 32 is in the receiving notch 13, a moving wheel 33 is fixed on the side away from the top cover 11; when the distribution box needs to be moved, the top cover 11 can be flipped with the distribution box to a moving state facing the ground, and the positioning rod 32 is in the receiving notch 13. At this time, the moving wheel 33 can abut against the ground, and the staff can hold the insulating pull rod 44 to more conveniently push the distribution box to move a short distance.

[0037] Reference Figure 7 、 Figure 8 and Figure 9 , a limiting shaft 412 is fixedly provided on the outer periphery of the ends of the two traction rods 41 close to the top cover 11, and two opposite limiting blocks 17 are fixedly provided on the vertical outer surface of the box body 1; a limiting slide 171 for inserting and sliding the limiting shaft 412 is opened in the vertical direction on the side surfaces of the two limiting blocks 17 close to each other, so that the traction rod 41 can rotate around the axis of the limiting shaft 412; a control member 5 for limiting the rotation of the traction rod 41 is provided on the box body 1, and the control member 5 releases the rotation limit of the traction rod 41 when the positioning rod 32 rotates into the receiving notch 13, and limits the rotation of the traction rod 41 when it rotates out of the receiving notch 13; When the distribution box is in a state convenient for short-distance movement, the top cover 11 faces the ground and the moving wheel 33 abuts the ground. At this time, the control component 5 releases the rotation limit of the traction rod 41, and the staff can rotate the traction rod 41 away from the box body 1 to an inclined state, so as to better tow the box body 1 for short-distance movement.

[0038] Reference Figure 8 and Figure 9 The control member 5 includes a locking plate 51 rotatably mounted on the inner wall of the box body 1, an adjusting member 53 for controlling the rotation of the locking plate 51, and a control insertion strip 52 fixedly mounted on the side of the traction rod 41 facing the box body 1. A guide groove 18 is vertically provided on the box body 1 for the control insertion strip 52 to be inserted and slide up and down; the rotating surface of the locking plate 51 is parallel to the inner wall of the box body 1 to which it is connected, and a control notch 521 is provided on the vertical side of the control insertion strip 52 close to the locking plate 51. The adjusting member 53 can drive the edge of the locking plate 51 to rotate into or out of the control notch 521.

[0039] Reference Figure 9 and Figure 10The adjusting member 53 includes an elastic reset member 531, an adjusting rod 533 slidably mounted on the inner wall of the box body 1 in the vertical direction, and a torsion spring 532 mounted on the locking plate 51; the torsion spring 532 is used to drive the locking plate 51 to rotate toward the control strip 52 and into the control notch 521; An adjustment hole 131 is formed on the bottom surface of the receiving notch 13, through which the end of the adjustment rod 533 passes. A control rod 534 is fixedly attached at an angle to the end of the adjustment rod 533 away from the top cover 11. The elastic return member 531 is used to drive the adjustment rod 533 to slide toward the top cover 11 until it protrudes from the adjustment hole 131. When the positioning rod 32 is rotated into the receiving notch 13, the positioning rod 32 presses the protrusion of the adjusting rod 533, and the locking plate 51 abuts and slides along the inclined surface of the control rod 534, so that the locking plate 51 is rotated out of the control notch 521 in the direction away from the control insert 52; when the positioning rod 32 is rotated out of the receiving notch 13, the elastic reset member 531 drives the adjusting rod 533 to reset, and at this time, under the action of the torsion spring 532, the locking plate 51 is rotated back into the control notch 521.

[0041] Reference Figure 10 A limit rod 535 parallel to the adjusting rod 533 is fixed to the end of the control rod 534 away from the adjusting rod 533. When the edge of the locking plate 51 turns into the control notch 521, one side of itself abuts against one side of the limit rod 535, thereby limiting the rotation range of the locking plate 51 through the limit rod 535.

[0042] The implementation principle of the embodiment of this application is: Installation auxiliary support state: When the distribution box is installed below the transformer on the pole, use a lifting device to move it to the appropriate position. The top cover 11 is equipped with a fixing assembly 3. First, rotate the positioning rod 32 out from above the top cover 11, move it to the correct position, and then rotate it back. At this time, the pole crossarm is located between the positioning rod 32 and the top cover 11. The fixing rod 31 and the positioning rod 32 provide auxiliary support, eliminating the need for a lifting device to continuously support the bottom, facilitating installation operations.

[0043] Heat dissipation and protection adjustment state: When the outdoor environment is harsh, the staff drives the traction rod 41 upward, and the elastic clamping member 43 snaps into the corresponding positioning groove 16. At this time, the blocking plate 42 blocks the opening of the protective cover 15. When the environment is good, the traction rod 41 moves downward to release the blockage. The staff can also operate the traction rod 41 through the insulating pull rod 44, which is safer and more convenient.

[0044] Movement and Limit Control: When the positioning rod 32 is retracted, the moving wheels 33 engage. When the distribution box is flipped so that the top cover 11 faces the ground, the moving wheels 33 contact the ground, facilitating short-distance movement. At this point, the control member 5 releases the rotation limit on the traction rod 41, allowing the traction rod 41 and the blocking plate 42 to be tilted to act as a "handle" to better pull the box body 1.
