Description

Technical Field

[0001] This application relates to the technical field of distribution cabinets, and in particular to a distribution cabinet with low energy consumption for heat dissipation. Background Art

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

[0003] In related technologies, the traditional design of a distribution cabinet usually includes a cabinet body and a cabinet door hinged thereto, and the cabinet door is securely locked through a mechanical lock structure. Inside the cabinet door, in order to support and fix electrical components (such as circuit breakers), several horizontal plates are pre-installed. These horizontal plates are often fixed to the inner wall of the cabinet firmly by screws or direct welding. However, the sizes of electrical components are diverse, and their requirements for installation space vary. Ideally, the spacing between the horizontal plates should be flexibly adjustable according to the size of the components to ensure efficient space utilization and reasonable component layout.

[0004] However, the fixing method of the horizontal plates in the prior art, especially the welding fixation, significantly limits the adjustability of their installation height. When facing electrical components of different sizes, it is difficult for the staff to quickly adjust the position of the horizontal plates to meet the installation requirements, which often leads to uneven layout during the installation of electrical components. Some areas may have a risk of overheating due to dense components, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a distribution cabinet with low energy consumption for heat dissipation, and solve the problem that the horizontal plates in the above-mentioned related technologies cannot be quickly adjusted adaptively.

[0006] A distribution cabinet with low energy consumption for heat dissipation provided by this application adopts the following technical solutions:

[0007] A distribution cabinet with low energy consumption for heat dissipation includes a cabinet body and a cabinet door. One vertical edge of the cabinet door is hinged to the cabinet body, and the other edge of the cabinet door is detachably connected to the cabinet body. A heat dissipation opening is provided on the side wall of the cabinet body, and a protective cover with a downward opening is fixedly provided on the outer opening edge of the cabinet body at the heat dissipation opening; on the opposite two vertical inner walls of the cabinet body, two vertical plates are relatively installed along the vertical direction, and several horizontal plates are provided between the two vertical plates; a plurality of waist-shaped holes are evenly opened on the vertical plates along the vertical direction, and locking screw holes are opened at both ends of the horizontal plates; locking bolts are provided in the cabinet body and penetrate through the waist-shaped holes and then are screwed into the locking screw holes.

[0008] By adopting the above technical solution, two vertical plates are relatively installed vertically 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 vertically on the vertical plates, locking screw holes are opened at both ends of the horizontal plates, and locking bolts that pass through the waist-shaped holes and are screwed into the locking screw holes are arranged inside the cabinet body, realizing the 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, thus ensuring a reasonable layout of the electrical components and efficient utilization of space.

[0009] Optionally, the vertical plates are fixedly arranged on the inner wall of the cabinet body.

[0010] By adopting the above technical solution, the fixed vertical plates serve as the reference and support for the installation of the horizontal plates, which can ensure that the horizontal plates remain horizontal and stable during the adjustment process, avoiding affecting the installation accuracy and safety of the electrical components due to shaking or deviation. In addition, the fixed connection between the vertical plates and the inner wall of the cabinet body also simplifies the installation steps and reduces the extra workload caused by frequently adjusting the positions of the vertical plates.

[0011] Optionally, the vertical plates are slidably arranged on the inner wall of the cabinet body, there is a gap between the lower end of the vertical plates and the bottom side of the cabinet body, and the vertical plates can slide up and down along the vertical direction; a driving member for driving the vertical plates to move up and down is arranged inside the cabinet body.

[0012] By adopting the above technical solution, this design allows the staff to quickly and accurately adjust the heights of the vertical plates and the horizontal plates according to the actual installation requirements of the electrical components, thus optimizing the layout of the electrical components and the utilization of space. The introduction of the driving member further simplifies the adjustment process, reduces manual operation, and improves work efficiency. At the same time, the gap between the vertical plates and the bottom side of the cabinet body ensures the smoothness of the sliding, avoiding potential damage to the vertical plates and the cabinet body caused by jamming or friction.

[0013] Optionally, the driving member includes an electric cylinder fixedly arranged on the inner wall of the cabinet body along the vertical direction, a receiving rod is fixedly arranged on the side edge of the vertical plate facing the cabinet door and above the electric cylinder, the end of the telescopic rod of 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.

[0014] By adopting the above technical solution, the electric cylinder as the driving member can stably and accurately control the up and down movement of the vertical plates. The vertically upward design of its telescopic rod ensures an effective connection with the receiving rod, thus realizing the precise control of the position of the vertical plates. The receiving rod is fixedly arranged 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 inside the cabinet body. In addition, the electric cylinder is fixedly arranged on the inner wall of the cabinet body along the vertical direction, making the entire driving system compact in structure and stable in operation, further improving the reliability and service life of the power distribution cabinet.

[0015] 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] Optionally, limiting rods are fixedly arranged opposite to each other on the lower side edge of the rain shield, limiting blocks are fixedly arranged on the two opposite vertical side surfaces of the waterproof cover, and limiting through holes for the limiting rods to penetrate are formed in the limiting blocks; a sealing plate for blocking the water diversion through hole is slidably arranged on the inner wall of the water diversion groove, the lower end of the limiting rod is hinged with a transmission rod, and the other end of the transmission rod is hinged with the upper side edge of the sealing plate; when the limiting rod moves downwards along with the rain shield, the transmission rod drives the sealing plate to slide, and the blocking of the water diversion through hole is released; when the limiting rod moves upwards, the sealing plate is driven to slide in the reverse direction to block the water diversion through hole.

[0026] By adopting the above technical solution, when the rain shield moves downwards along with the vertical plate, the limiting rod drives the sealing plate to slide through the transmission rod, automatically releasing the blocking of the water diversion through hole, so that the accumulated water in the water diversion groove can be discharged in time; when the rain shield moves upwards, the limiting rod drives the sealing plate to slide in the reverse direction to re-block the water diversion through hole, preventing rainwater from seeping into the cabinet body through the water diversion through hole. This design not only simplifies the operation process, improves the work efficiency, but also effectively enhances the waterproof performance and operation stability of the power distribution cabinet.

[0027] In summary, the present application includes the following beneficial technical effects:

[0028] By adopting the design of relatively installing two vertical plates in the vertical direction on the two opposite vertical inner walls of the cabinet body and arranging a plurality of horizontal plates between the two vertical plates, and at the same time, a plurality of waist-shaped holes are evenly formed in the vertical direction on the vertical plates, locking screw holes are formed at both ends of the horizontal plates, and locking bolts passing through the waist-shaped holes and screwed into the locking screw holes are arranged in the cabinet body, the quick adaptive adjustment of the installation height of the horizontal plates is realized.

[0046] Embodiment 2:

[0047] Referring to Figure 4 and Figure 5 , the difference between the embodiment of this application and Embodiment 1 is that the vertical plates 31 are slidably arranged on the inner wall of the cabinet body 1, there is a gap between the lower end of the vertical plates 31 and the bottom side of the cabinet body 1, and the vertical plates 31 can slide up and down in the vertical direction; a driving member 4 for driving the vertical plates 31 to move up and down is arranged inside the cabinet body 1;

[0048] The staff can adjust the height of the support assembly 3 through the driving member 4, which not only improves the flexibility and convenience of the height adjustment of the support assembly 3, but also enhances the stability and safety of the power distribution cabinet.

[0049] Referring to Figure 5 , the driving member 4 includes two electric cylinders 41 fixedly arranged on the opposite two vertical inner walls of the cabinet body 1 in the vertical direction. On the side edges of the two vertical plates 31 facing the cabinet door 2, a receiving rod 312 located above the electric cylinders 41 is fixedly arranged horizontally, and the end of the telescopic rod on the electric cylinders 41 is vertically upward. The upper end of the electric cylinders 41 is fixedly connected to the lower side of the receiving rod 312; by starting the electric cylinders 41, the receiving rod 312 and the vertical plates 31 are driven to move up and down as a whole for adjustment.

[0050] Referring to Figure 5 and Figure 6A waterproof cover 5 is fixedly provided on the top of the cabinet 1, wherein a support plane 51 is provided in the middle of the upper side of the waterproof cover 5, and the waterproof cover 5 is symmetrically provided with water-guiding slopes 52 inclined downward on the two opposite sides of the support plane 51; a rain shield 6 is provided above the waterproof cover 5, and there is a gap between the rain shield 6 and the waterproof cover 5, and the waterproof cover 5 is provided with a plurality of vents 511 located below the rain shield 6 on the support plane 51;

[0052] Reference Figure 5 Two support rods 61 are fixedly provided on the lower side of the rain shield 6, wherein the waterproof cover 5 is provided with a support through hole 512 on the support plane 51 for the support rod 61 to penetrate and slide; a traction member 7 for driving the support rod 61 to move downward, and a reset member 8 for driving the support rod 61 to move upward and reset are provided in the cabinet 1. When the rain shield 6 moves downward with the support rod 61, the vent 511 (that is, the gap between the rain shield 6 and the waterproof cover 5) is blocked, and when it moves upward, the vent 511 is unblocked.

[0053] Reference Figure 6 and Figure 7 The reset member 8 includes a spring 81 and a stopper 82 fixed on the outer periphery of the support rod 61. The spring 81 is made of a high-strength material (such as high-carbon steel, stainless steel, etc.), has good resilience and a long service life; a support groove 513 for the stopper 82 to be placed and slide is provided on the upper opening edge of the support through hole 512 on the waterproof cover 5. The lower end of the spring 81 is fixedly connected to the bottom side of the support groove 513, and the upper end of the spring 81 is fixedly connected to the lower side of the stopper 82;
