Description

Technical Field

[0001] The present invention relates to the technical field of dehumidifying and moisture-proof marine electrical control cabinet equipment, and specifically relates to an adaptable environment dehumidifying and moisture-proof marine electrical control cabinet. Background Technique

[0002] In our daily life, an electrical control cabinet is a common cabinet for installing electronic components, which is made of metal materials to protect the normal operation of its internal electronic components. It is usually fixedly installed on the wall or directly placed on the ground. According to different uses, it can be divided into low-voltage electrical control cabinets, high-voltage electrical control cabinets, outdoor electrical control cabinets, etc. Electrical cabinets are widely used mainly in the environmental protection industry, power systems, metallurgical systems, nuclear power industries, fire safety monitoring, etc., and control cabinets are also used in the marine industry.

[0003] However, during the use of marine electrical control cabinets, due to the fact that ships sail on the sea all year round, the air humidity is usually high, and the high-humidity air is very easy to enter the interior of the control cabinet. Due to the principle that hot air rises and cold air sinks, the bottom of the control cabinet will get damp. Over time, it will not only cause rust on the control cabinet, but also affect the use of control components. Summary of the Invention

The end of the lower push disk is rotatably connected with a sealing disk; A diffusion mechanism, the diffusion mechanism includes a push plate. The end of the push plate is fixedly connected with a diffusion disk.

[0006] Furthermore, the surface of the cabinet door is fixedly connected with a handle. Heat dissipation holes are opened on both sides of the control cabinet. The number of cabinet doors is set to two, and the two cabinet doors are symmetrically arranged on the surface of the control cabinet.

[0007] Further, the heat dissipation mechanism includes a gear shaft, a heat dissipation fan is fixedly connected to the end of the gear shaft, a protective cover is fixedly connected to the inner wall of the control cabinet, centralized funnels are fixedly connected to both sides of the control cabinet, and a helical gear is fixedly connected to the end of the transmission shaft away from the motor.

[0008] Further, the surface of the helical gear meshes with the surface of the gear shaft, the surface of the gear shaft is rotatably connected to the inner wall of the support ring, the end of the heat dissipation pipe is fixedly connected to the end of the centralized funnel, and the end of the heat dissipation fan away from the gear shaft is rotatably connected to the inner wall of the protective cover.

[0009] Further, the dehumidification mechanism includes a transmission pipe, a dehumidification circular pipe is fixedly connected to the surface of the transmission pipe, a spray pipe is fixedly connected to the bottom of the transmission pipe, an electric push rod is fixedly connected to the surface of the control cabinet, a sliding disk is fixedly connected to the end of the electric push rod, and a limiting elastic rod is fixedly connected to the bottom of the sliding disk.

[0010] Further, the surface of the transmission pipe communicates with the surface of the heat dissipation pipe, a chute is opened on the upper surface of the inner wall of the transmission pipe, the outer wall of the sliding disk is slidably connected to the inner wall of the chute, the end of the limiting elastic rod away from the sliding disk is fixedly connected to the inner wall of the chute, the end of the lower push disk away from the sealing disk is rotatably connected to the bottom of the sliding disk, the outer wall of the sealing disk is rotatably connected to the lower surface of the inner wall of the transmission pipe, the end of the driven pull rod away from the sealing disk is rotatably connected to the surface of the sealing disk, and the outer wall of the sealing disk contacts the inner wall of the transmission pipe.

[0011] Further, the diffusion mechanism includes a driven frame, an elastic plate is fixedly connected to the bottom of the driven frame, and a scraping plate is fixedly connected to the bottom of the push plate.

[0012] Further, the end of the driven frame away from the elastic plate is fixedly connected to the surface of the electric push rod, the end of the push plate away from the diffusion disk is fixedly connected to the surface of the elastic plate, and diffusion grooves are formed on the surface of the diffusion disk.

[0013] The present invention has the following beneficial effects: By setting the heat dissipation mechanism, the motor is first started to drive the transmission shaft to rotate. When the transmission shaft rotates, it will drive the gear shaft to rotate. When the gear shaft rotates, it will drive the heat dissipation fan to rotate. When the heat dissipation fan rotates, the heat dissipated by the control components will be transmitted to the inside of the centralized funnel through the heat dissipation holes, and then the heat will be concentrated by the centralized funnel and transmitted to the outside through the heat dissipation pipe. During the transmission of the heat dissipation pipe, the sealing disk is in an open state and does not block the heat transmission, effectively delivering the heat energy dissipated by the control components inside the control cabinet, thereby avoiding damage caused by excessive heat dissipated by the control components and improving the service life.

[0014] In the present invention, by providing a dehumidification mechanism, when dehumidifying the bottom inside the control cabinet, the electric push rod is activated to push the sliding plate to slide downward along the inner wall of the chute. When the sliding plate slides, it will squeeze the limiting elastic rod. When the limiting elastic rod is squeezed, it will contract downward. When the limiting elastic rod contracts to a certain position, it will limit the sliding plate to prevent the sliding plate from contacting the bottom of the inner wall of the chute. When the sliding plate moves downward, it will push the lower push plate downward. When the lower push plate moves, it will push the sealing disc downward and rotate downward at an angle of 45 degrees. At this time, during the movement of the sealing disc, it will pull the driven pull rod downward. When the driven pull rod moves, it will pull the sealing disc downward and rotate downward at an angle of 45 degrees, thereby sealing the inner wall of the heat dissipation pipe and blocking the transmitted hot air. At this time, the sealing disc is in an open state, and the hot air will be transmitted into the interior of the transmission pipe. At this time, the hot air will pass through the interior of the transmission pipe, and then the hot air will be transmitted into the interior of the dehumidification circular pipe, and finally transmitted to the bottom of the inner wall of the control cabinet. Finally, the hot air is also transmitted to the bottom of the inner wall of the control cabinet through the spray pipe to dry the damp bottom of the control cabinet. When the temperature inside the control cabinet is too high, the electric push rod will reset. At this time, the sealing disc will close, and the sealing disc will be opened through the driven pull rod, so as to utilize the heat dissipated by the control components and dehumidify the interior of the control cabinet, thereby reducing the damage to the control cabinet and the control components.

[0015] In the present invention, by providing a diffusion mechanism, when the electric push rod extends downward, it will push the driven frame downward. When the driven frame moves, it will squeeze the elastic plate. When the elastic plate is squeezed, the middle part will bend. When the middle part of the elastic plate bends, it will push the push plate to move in the direction of approaching each other. When the push plate moves, it will push the diffusion disc to move in the direction of approaching each other and contact the surface of the spray pipe, without affecting the spray pipe for exhausting air. Since the bottom of the dehumidification circular pipe is provided with air outlet holes, at this time, the diffusion disc moves to the lower part of the dehumidification circular pipe. When the air outlet holes exhaust air, the exhausted hot air can be diffused around through the diffusion grooves on the surface of the diffusion disc, increasing the diffusion range of the hot air and improving the dehumidification efficiency. When the push plate moves, it will drive the scraper to move in the direction of approaching each other. When the scraper moves, it will scrape the bottom of the inner wall of the control cabinet to prevent the accumulation of moisture in local positions and the phenomenon of water accumulation, thereby improving the dehumidification efficiency.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the sealing disc 38 is in an open state, and the hot air will be transmitted into the inside of the transmission pipe 31. At this time, the hot air will pass through the inside of the transmission pipe 31, then be transmitted into the inside of the dehumidifying circular pipe 32, and finally be transmitted to the bottom of the inner wall of the control cabinet 1. Finally, the hot air is also transmitted to the bottom of the inner wall of the control cabinet 1 through the spray pipe 33 to dry the damp bottom of the control cabinet 1. When the temperature inside the control cabinet 1 is too high, the electric push rod 34 will be reset. At this time, the sealing disc 38 will close, and the sealing disc 16 will be opened through the driven pull rod 17. When the electric push rod 34 extends downward, it will push the driven frame 51 downward. When the driven frame 51 moves, it will squeeze the elastic plate 52. When the elastic plate 52 is squeezed, the middle part will bend. When the middle part of the elastic plate 52 bends, it will push the push plate 53 to move toward each other. When the push plate 53 moves, it will push the diffusion disc 54 to move toward each other and contact the surface of the spray pipe 33, and it does not affect the spray pipe 33 from exhausting air. Since the bottom of the dehumidifying circular pipe 32 is provided with air outlet holes, at this time, the diffusion disc 54 moves to the lower part of the dehumidifying circular pipe 32. When the air outlet holes exhaust air, the discharged hot air can be diffused around through the diffusion grooves on the surface of the diffusion disc 54, increasing the diffusion range of the hot air and improving the dehumidification efficiency.
