Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and in particular to a protective structure of a power distribution cabinet. Background Art

[0002] A distribution cabinet is a metal cabinet with electrical components placed inside. By placing the electrical components inside the distribution cabinet, it can not only provide certain protection for the electrical components, but also facilitate maintenance by the staff. Therefore, the distribution cabinet has become an indispensable part of the power supply equipment.

[0003] At present, the general protection structure of the distribution cabinet is to prevent the distribution cabinet from being damaged by rain by providing a shielding cover on the top of the cabinet and providing a support frame and a cooling fan inside the cabinet.

[0004] However, some existing distribution cabinets are usually installed outdoors, and it is easy to encounter rainy days outdoors. When encountering heavy rain, rainwater may penetrate into the interior of the distribution cabinet, causing the electrical appliances inside the distribution cabinet to be easily damaged. Summary of the invention

[0005] In order to improve the safety of a power distribution cabinet, the present application provides a protection structure for a power distribution cabinet.

[0006] The present application provides a distribution cabinet protection structure, which adopts the following technical solutions: A power distribution cabinet protection structure, comprising: A cabinet body, one side of which is open, and a cabinet door is hinged at the open end, and heat dissipation openings are provided on both side walls of the cabinet body; A rain shield assembly is disposed on the top of the cabinet and is used to shield the cabinet from rain; The shielding components are provided in two groups, and the two groups of shielding components are respectively provided at the two groups of heat dissipation ports, and the shielding components include a sensing part and a shielding part; A dehumidification component, comprising a diffusion part, a transmission part and a dehumidification part; in, The sensing part is arranged on the rain shield component and is used to detect the rainfall; the shielding part is arranged at the heat dissipation port and is used to close the heat dissipation port; the diffusion part, the transmission part and the dehumidification part are all arranged in the cabinet body, and when the rainfall exceeds a preset value, the diffusion part blows and stirs the moisture in the cabinet body, and the transmission part drives the dehumidification part to rotate, and the dehumidification part absorbs the moisture in the cabinet body during the rotation process.

[0007] By adopting the above technical solution, when encountering heavy rain, the rain shielding component shields the cabinet from rain, and the sensing part detects the rainfall. When the rainfall reaches the first set value, the shielding part closes the heat dissipation port, thereby reducing the possibility of moisture entering the cabinet from the heat dissipation port; then, the sensing part continues to detect the rainfall. When the rainfall reaches the second set value, it means that the moisture inside the cabinet has exceeded the set value. The diffusion part blows and diffuses the deposited moisture, and the transmission part drives the dehumidification part to rotate. During the rotation, the dehumidification part absorbs the moisture in the cabinet, thereby effectively reducing the humidity in the cabinet, preventing moisture from corroding electrical components, and improving the working stability and service life of the equipment inside the distribution cabinet, thereby easily improving the safety of the distribution cabinet.

[0008] Optionally, the rain shield assembly includes: A V-shaped rain shield, covering the top of the cabinet; There are two guide grooves, which are respectively located below the two ends of the V-shaped rain shield, and the notch direction of the guide groove is arranged toward the side of the V-shaped rain shield, and the guide groove is connected to the cabinet; Wherein, a drainage hole is provided on the side wall of the guide groove away from the cabinet, and the drainage hole is located near the notch of the guide groove.

[0009] By adopting the above technical solution, when rainwater falls on the top of the distribution cabinet, it can be quickly guided by the V-shaped structure and slide down to both sides and enter the guide groove, effectively preventing rainwater from accumulating on the top of the distribution cabinet, thereby reducing the risk of rainwater directly invading the interior of the distribution cabinet; The drainage holes allow the accumulated water to be quickly discharged from the drainage holes to avoid accumulation in the guide groove, thereby further improving the rainproof performance of the distribution cabinet.

[0010] Optionally, the sensing unit includes: A pressure-bearing telescopic rod is fixedly mounted on the cabinet, and a movable end of the pressure-bearing telescopic rod is fixedly connected to the guide groove; The displacement sensor is fixedly mounted on the movable end of the pressure-bearing telescopic rod and is used to output a travel signal of the movable end of the pressure-bearing telescopic rod.

[0011] By adopting the above technical solution, when rainwater accumulates in the diversion groove, under the action of the gravity of the rainwater, downward pressure is generated on the pressure-bearing telescopic rod, the movable end of the pressure-bearing telescopic rod moves, and the displacement sensor outputs a travel signal of the movable end of the pressure-bearing telescopic rod. When the first set value is reached, the displacement sensor transmits a signal to the shielding part, and the shielding part closes the heat dissipation port; The expansion and contraction of the pressure-bearing telescopic rod is converted into a displacement signal, which is captured and output by the displacement sensor. This enables the system to accurately judge the amount of rainfall and provide a basis for subsequent control decisions. This automated control mechanism improves the protection efficiency and response speed of the distribution cabinet.

[0012] Optionally, the shielding portion includes: An electric telescopic rod, fixedly arranged in the cabinet and electrically connected to the displacement sensor; The baffle is fixedly connected to the movable end of the electric telescopic rod and is arranged parallel to the side wall of the cabinet. The baffle is slidably connected to the cabinet through a guide rail and is used to cover the heat dissipation port.

[0013] By adopting the above technical solution, when the first set value is reached, the displacement sensor outputs a travel signal of the movable end of the pressure-bearing telescopic rod to the electric telescopic rod, and the electric telescopic rod drives its movable end to extend, thereby driving the baffle to slide along the guide rail to block the heat dissipation port. This intelligent control mechanism can quickly respond to changes in rainfall, thereby easily ensuring the safety of equipment inside the distribution cabinet.

[0014] Optionally, the diffusion part includes: A motor, fixed on the cabinet and electrically connected to the displacement sensor; An intermediate gear, coaxially connected to the output shaft of the motor; There are multiple driven gears, which are arranged around the axis of the intermediate gear. The driven gears are meshed with the intermediate gears and are rotatably connected to the cabinet body. Wherein, the driven gear is coaxially fixed with a fan.

[0015] By adopting the above technical solution, when rainwater continues to accumulate in the diversion groove, the gravity of the rainwater generates downward pressure on the pressure-bearing telescopic rod, and the movable end of the pressure-bearing telescopic rod moves. The displacement sensor outputs a stroke signal of the movable end of the pressure-bearing telescopic rod. When the second set value is reached, the stroke signal of the movable end of the pressure-bearing telescopic rod is transmitted to the motor to drive it to start. The motor drives the intermediate gear to rotate, and the intermediate gear drives these driven gears and the coaxially fixed fan to rotate synchronously through meshing with multiple driven gears, thereby accelerating the air flow inside the cabinet, making it difficult for moisture to deposit at the bottom of the cabinet, thereby making it easy for the dehumidification part to absorb moisture.

[0016] Optionally, the transmission unit includes: A first rotating shaft, coaxially connected to the intermediate gear; A second rotating shaft is rotatably connected to the cabinet; There are two connecting gears, which are respectively coaxially fixed to the rotating shaft 1 and the rotating shaft 2, and the two connecting gears are meshed.

[0017] By adopting the above technical solution, the motor drives the intermediate gear to rotate, the intermediate gear drives the connecting gear to rotate, the connecting gear drives another connecting gear to rotate, and the other connecting gear drives the rotating shaft 2 to rotate, so that the rotating shaft 1 and the rotating shaft 2 rotate in opposite directions, which can achieve efficient power transmission and improve the operating efficiency of the overall system.

[0018] Optionally, the dehumidification part is provided with two groups, and the two groups of the dehumidification parts are respectively provided on the first rotating shaft and the second rotating shaft, and the dehumidification part includes: A plurality of connecting rods are provided, the plurality of connecting rods are arranged around the axis of the first rotating shaft, and one end of the connecting rod is fixedly connected to the first rotating shaft; A dehumidifying ball, which is hollow inside and fixedly connected to an end of the connecting rod away from the rotating shaft; The dehumidifying ball is provided with a plurality of through holes, and the dehumidifying ball is filled with calcium chloride dehumidifying particles.

[0019] By adopting the above technical solution, the first and second rotating shafts respectively drive two groups of dehumidification parts to rotate. In one group, the first rotating shaft drives the connecting rod to rotate, and the connecting rod drives the dehumidification ball to rotate. The dehumidification ball contacts the stirred moisture. The dynamic dehumidification method helps to speed up the air flow, thereby facilitating the improvement of the dehumidification efficiency. Since calcium chloride has strong hygroscopicity, it can quickly absorb moisture in the air, thus easily reducing the humidity inside the distribution cabinet.

[0020] Optionally, a plurality of drainage holes are provided, and the plurality of drainage holes are arranged along the length direction of the guide groove.

[0021] By adopting the above technical solution, when water flows into the guide groove from all directions, these drainage holes can quickly guide and discharge the water, thereby improving the drainage efficiency.

[0022] Optionally, a dust shield is provided at the heat dissipation port, and the dust shield is fixedly mounted on the outer wall of the cabinet.

[0023] By adopting the above technical solution, dust and impurities in the external air can be effectively blocked, and the internal environment of the cabinet can be kept clean.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: By providing the sensing part and the shielding part, the possibility of moisture entering the cabinet from the heat dissipation port is reduced, thereby making it easier to ensure the safety of the equipment inside the power distribution cabinet; By setting up the diffusion part, the transmission part and the dehumidification part, the dynamic dehumidification method helps to speed up the air flow, thereby facilitating the improvement of the dehumidification efficiency and thus facilitating the reduction of the humidity inside the power distribution cabinet; By setting up V-shaped rain shields and guide grooves, rainwater can be effectively prevented from accumulating on the top of the distribution cabinet, thereby reducing the risk of rainwater directly invading the interior of the distribution cabinet.
