[0002] The power distribution cabinet is the core component of the power system, and undertakes the important functions of power distribution, control, protection and monitoring. With the development of industrial automation and intelligence, the power distribution cabinet plays an irreplaceable role in many fields such as industrial production, building electrical, and power systems.

[0003] In the related art, the traditional power distribution cabinet design usually includes a cabinet body and a cabinet door hinged thereon, and the cabinet door is securely locked by a mechanical lock structure. On the inside of the cabinet door, in order to support and fix electrical components (such as circuit breakers), several cross plates are pre-installed. These cross plates are often fixed to the inner wall of the cabinet by screws or direct welding. However, electrical components come in various sizes and have different requirements for installation space. Ideally, the spacing between the cross plates should be able to be flexibly adjusted according to the size of the components to ensure efficient space utilization and reasonable component layout.

[0004] However, the fixing method of the horizontal plate in the prior art, especially welding fixing, significantly limits the adjustability of its installation height. When faced with electrical components of different sizes, it is difficult for workers to quickly adjust the position of the horizontal plate to meet installation requirements, which often leads to uneven layout of electrical components during installation. Some areas may have overheating risks due to dense components, and there is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a power distribution cabinet with low energy consumption and heat dissipation, so as to solve the problem that the horizontal plate in the above-mentioned related technology cannot be quickly and adaptively adjusted.

[0006] The present application provides a low-energy heat dissipation distribution cabinet adopts the following technical solution: A low-energy heat dissipation distribution cabinet comprises a cabinet body and a cabinet door, wherein a vertical edge on one side of the cabinet door is hinged to the cabinet body, and an edge on the other side of the cabinet body is detachably connected to the cabinet body, a heat dissipation port is provided on the side wall of the cabinet body, and a protective cover with an opening downward is fixed to the outer opening edge of the heat dissipation port; two vertical plates are relatively installed on two opposite vertical inner walls of the cabinet body in a vertical direction, and a plurality of horizontal plates are provided between the two vertical plates; a plurality of waist-shaped holes are evenly provided on the upper sides of the vertical plates, and locking screw holes are provided at both ends of the horizontal plates; a locking bolt is provided in the cabinet body and passes through the waist-shaped hole and is screwed into the locking screw hole.

[0007] By adopting the above technical solution, two vertical plates are installed on two opposite vertical inner walls of the cabinet in the vertical direction, and a number of horizontal plates are arranged between the two vertical plates. At the same time, a number of waist-shaped holes are evenly opened in the vertical direction on the upper side of the vertical plates, locking screw holes are opened at both ends of the horizontal plates, and locking bolts are set in the cabinet body and then screwed into the locking screw holes after passing through the waist-shaped holes, so as to achieve rapid adaptive adjustment of the installation height of the horizontal plates. This design enables the staff to quickly adjust the position of the horizontal plates to meet the installation requirements when facing electrical components of different sizes, thereby ensuring a reasonable layout of electrical components and efficient space utilization.

[0008] Optionally, the vertical plate is fixed on the inner wall of the cabinet.

[0009] By adopting the above technical solution, the fixed vertical plate serves as the reference and support for the installation of the horizontal plate, which can ensure that the horizontal plate remains horizontal and stable during the adjustment process, avoiding shaking or offset that affects the installation accuracy and safety of electrical components. In addition, the fixed connection between the vertical plate and the inner wall of the cabinet also simplifies the installation steps and reduces the extra workload caused by frequent adjustment of the vertical plate position.

[0010] Optionally, the vertical plate is slidably mounted on the inner wall of the cabinet, a gap exists between the lower end of the vertical plate and the bottom of the cabinet, and the vertical plate can slide up and down in the vertical direction; a driving member is provided inside the cabinet to drive the vertical plate to move up and down.

[0011] By adopting the above technical solution, this design allows the staff to quickly and accurately adjust the height of the vertical plate and the horizontal plate according to the actual installation requirements of the electrical components, thereby optimizing the layout of the electrical components and space utilization. The introduction of the drive further simplifies the adjustment process, reduces manual operation, and improves work efficiency. At the same time, the spacing between the vertical plate and the bottom side of the cabinet ensures smooth sliding and avoids potential damage to the vertical plate and the cabinet caused by jamming or friction.

[0012] Optionally, the driving member includes an electric cylinder fixed on the inner wall of the cabinet in a vertical direction, a receiving rod located above the electric cylinder is fixed on the side edge of the vertical plate facing the cabinet door, the end of the telescopic rod on the electric cylinder is vertically upward, and the upper end of the electric cylinder is fixedly connected to the lower side of the receiving rod.

[0013] By adopting the above technical solution, the electric cylinder as a driving part can stably and accurately control the up and down movement of the vertical plate. The vertical upward design of its telescopic rod ensures the effective connection with the receiving rod, thereby realizing the precise control of the position of the vertical plate. The receiving rod is fixed on the side edge of the vertical plate facing the cabinet door, which not only ensures the firmness of the connection, but also avoids affecting other layouts in the cabinet. In addition, the electric cylinder is fixed on the inner wall of the cabinet in the vertical direction, making the entire drive system compact and running smoothly, further improving the reliability and service life of the distribution cabinet.

[0014] Optionally, a waterproof cover is fixedly provided on the top of the cabinet, a supporting plane is provided in the middle of the upper side surface of the waterproof cover, and the waterproof cover is symmetrically provided with downwardly inclined water-guiding slopes on the opposite side edges of the supporting plane; a rain shield is provided above the waterproof cover, and there is a gap between the rain shield and the waterproof cover, and a plurality of ventilation holes are provided on the supporting plane below the rain shield; a mounting hole connected to the ventilation holes is provided on the upper side of the cabinet, and an air guide fan is embedded on the inner wall of the mounting hole.

[0015] By adopting the above technical solution, the waterproof cover effectively blocks the invasion of external rainwater into the interior of the cabinet, and the water-guiding slope design ensures that rainwater is quickly discharged to avoid water accumulation. The gap between the rain shield and the waterproof cover and the setting of the vents not only ensure air circulation, but also prevent rainwater from directly infiltrating. The introduction of the air guide fan further enhances the air convection inside the distribution cabinet, improves the heat dissipation effect, and ensures the stable operation of electrical components. Therefore, this technical solution not only enhances the protection performance of the distribution cabinet, but also optimizes its heat dissipation structure, providing a strong guarantee for the stable operation of the distribution cabinet in harsh environments.

[0016] Optionally, a plurality of support rods are fixedly provided on the lower side of the rain shield, and a support through hole for the support rods to pass through is opened on the waterproof cover; a traction member for driving the support rods to move downward, and a reset member for driving the support rods to move upward and reset are provided in the cabinet; the rain shield blocks the vents when the support rods move downward, and releases the blockage of the vents when the support rods move upward.

[0017] By adopting the above technical solution, the fixed connection between the support rod and the rain shield, and the cooperation of the traction member and the reset member, the rain shield can automatically adjust its position according to the external environmental conditions, effectively blocking or opening the vents. In severe weather conditions, such as heavy rain or strong winds, the rain shield moves down to block the vents to prevent rainwater from intruding; in good weather or when heat dissipation is required, the rain shield moves up to release the blockage and ensure air circulation. This design not only enhances the waterproof performance of the distribution cabinet, but also optimizes its heat dissipation structure and improves the operating stability and service life of electrical components.

[0018] Optionally, the traction member is a traction rope placed in the cabinet, one end of the traction rope is fixedly connected to the upper end of the receiving rod, and the other end of the traction rope passes through the top of the box and is fixedly connected to the lower end of the support rod; when the vertical plate moves downward, the support rod is driven downward by the traction rope.

[0019] By adopting the above technical solution, a traction rope is used as a traction member, and one end of the traction rope is fixedly connected to the upper end of the receiving rod, and the other end is fixedly connected to the lower end of the support rod. The power distribution cabinet can control the position of the rain shield while adjusting the height of the vertical plate and the horizontal plate, realizing the integrated operation of height adjustment and vent opening and closing. When the vertical plate moves down, the traction rope pulls the support rod down, and the rain shield blocks the vent, effectively preventing rainwater from intruding; conversely, when the vertical plate moves up, the traction rope releases the tension on the support rod, the reset member moves the support rod up, and the rain shield releases the blockage of the vent to ensure air circulation. This design not only simplifies the operation process and improves work efficiency, but also enhances the automation and intelligence level of the power distribution cabinet.

[0020] Optionally, the reset member includes a spring and a block fixed on the outer periphery of the support rod, and the waterproof cover is provided with a support groove for the block to be placed and slide at the upper opening edge of the supporting through hole, the lower end of the spring is fixedly connected to the bottom side of the support groove, and the upper end of the spring is fixedly connected to the lower side of the block.

[0021] By adopting the above technical solution, when the vertical plate and the traction rope drive the support rod to move downward and the rain shield blocks the vent, the spring is in a compressed state. Once the vertical plate and the traction rope release the pulling force on the support rod, the spring immediately exerts its elastic force to push the block and the support rod upward, so that the rain shield can quickly and smoothly release the blockage of the vent. The design of the support trough ensures the stability and guidance of the block during movement, avoiding deviation or jamming. This reset method is not only simple in structure and easy to implement, but also can effectively ensure that the rain shield can block or open the vent in a timely and accurate manner when needed, thereby improving the automation and operation efficiency of the distribution cabinet.

[0022] Optionally, a water diversion groove opening upward is provided on the lower edge of the waterproof cover, and a water diversion through hole is provided on the bottom side of the water diversion groove.

[0023] By adopting the above technical solution, the water diversion trough can collect and temporarily store rainwater dripping from the edge of the rain shield, preventing it from dripping directly near the vent or on the top of the cabinet, reducing the risk of rainwater invading the interior of the cabinet. At the same time, the setting of the water diversion through hole allows the accumulated water in the water diversion trough to be discharged in time, avoiding overflow or leakage caused by excessive water accumulation. This design not only improves the waterproof effect of the distribution cabinet, but also ensures its long-term stability and safety.

[0024] Optionally, a limit rod is relatively fixedly provided on the lower edge of the rain shield, and limit blocks are fixedly provided on the two opposite vertical sides of the waterproof cover, and the limit blocks are provided with a limit hole for the limit rod to pass through; a sealing plate for blocking the water diversion hole is slidably provided on the inner wall of the water diversion trough, and a transmission rod is hinged at the lower end of the limit rod, and the other end of the transmission rod is hinged to the upper edge of the sealing plate; when the limit rod moves downward with the rain shield, the sealing plate is driven to slide through the transmission rod to release the blockage of the water diversion hole; when the limit rod moves upward, it drives the sealing plate to slide in the opposite direction to block the water diversion hole.

[0025] By adopting the above technical solution, when the rain shield moves down with the vertical plate, the limit rod drives the blocking plate to slide through the transmission rod, automatically releasing the blockage of the water diversion hole, so that the accumulated water in the water diversion trough can be discharged in time; and when the rain shield moves up, the limit rod drives the blocking plate to slide in the opposite direction, re-blocking the water diversion hole to prevent rainwater from seeping into the cabinet from the water diversion hole. This design not only simplifies the operation process and improves work efficiency, but also effectively enhances the waterproof performance and operation stability of the distribution cabinet.

[0026] In summary, this application includes the following beneficial technical effects: The design adopts that two vertical plates are installed relatively in the vertical direction on two opposite vertical inner walls of the cabinet body, and a number of horizontal plates are arranged between the two vertical plates. At the same time, a number of waist-shaped holes are evenly opened in the vertical direction on the upper portion of the vertical plates, and locking screw holes are opened at both ends of the horizontal plates. Locking bolts are arranged in the cabinet body and penetrate the waist-shaped holes and are screwed into the locking screw holes, thereby realizing rapid adaptive adjustment of the installation height of the horizontal plates.
