Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinets, and particularly to an electrical cabinet with a dehumidification function. Background Art

[0002] An electrical cabinet is a cabinet made of steel materials to protect components to work properly. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are relatively softer than hot-rolled steel plates and are more suitable for making electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] The patent with the publication number CN214411872U relates to an electrical cabinet with a dehumidification function. The above application includes an electrical cabinet body, an upper cover is installed at the upper end of the electrical cabinet body by means of bolt connection, and through holes are evenly formed in the right end face of the electrical cabinet body; a support seat, which is welded and fixed on the lower end face inside the electrical cabinet body, and a support frame for supporting is arranged on the upper end face of the support seat; a fan, which is installed on the left end face of the electrical cabinet body by means of bolt connection. The device is provided with a condensation pipe, a condensation plate and a receiving tray. The cold air instrument works to circulate cold air into the condensation pipe through an air pipe. At the same time, since the condensation pipes are arranged at equal intervals from top to bottom on the inner right end face of the electrical cabinet body, and the cross section of the condensation plate is arc-shaped, it is convenient to increase the contact area between the condensation plate and the air, the temperature inside the condensation mechanism decreases, so that the water vapor in the electrical cabinet body contacts the condensation plate and liquefies into small water droplets, and flows down along the condensation plate. Since the width of the upper end face of the receiving tray is greater than the width of the support plate, it is convenient to receive the water droplets falling from the condensation mechanism through the receiving tray and discharge them through a water outlet pipe, so as to prevent excessive moisture in the cabinet.

[0004] In the above electrical cabinet, when the condensation pipe is used for a long time, it is inevitable to adhere a large amount of scale and other deposits. And because the condensation pipe is installed inside the cabinet body, it is inconvenient to deal with the scale and other deposits on the outer wall of the condensation pipe, which will affect the drying effect of moisture, and it is easy to cause a large amount of moisture to enter the cabinet body, resulting in damage to electrical equipment. Summary of the Invention

[0007] According to the above technical solution, a pushing plate is slidably installed on the inner wall of the connection cover, a reset spring is fixed on the side wall of the pushing plate, and the side of the reset spring away from the pushing plate is fixed on the inner side of the inside of the connection cover.

[0008] According to the above technical solution, a winding groove is opened on the outer wall of the rotating sleeve, a steel wire rope is fixed on the inner wall of the winding groove, and the end of the steel wire rope away from the rotating sleeve is fixed on the pushing plate. When the rotating sleeve rotates, the winding groove opened on the outer wall of the rotating sleeve can wind the steel wire rope, so that the steel wire rope can pull the pushing plate, and the pushing plate moves along the inner wall of the connection cover.

[0009] According to the above technical solution, the knocking component includes a connecting rod, a pressing block, a support plate, a fixing plate, a transmission block, a transmission spring, a connecting rod, a hinge block, a knocking block, a connecting block and a rotating rod. One end of the connecting rod is fixed on the pushing plate, and the other end of the connecting rod is fixed with a pressing block. When the pushing plate moves, the pressing block can be driven to move through the connecting rod.

[0010] According to the above technical solution, a support plate is fixed to the outer wall of the connection cover. A transmission block passes through the support plate. A fixing plate is fixed to the bottom of the transmission block. A transmission spring is fixed to the top of the fixing plate, and the top of the transmission spring is fixed to the bottom of the support plate. When the extrusion block moves, the arc surface at the bottom of the extrusion block can extrude the arc surface at the top of the transmission block, causing the transmission block to move downward under the extrusion force and driving the fixing plate to move downward.

[0011] According to the above technical solution, a connection block is fixed to the bottom of the connection cover. A rotating rod is rotatably installed inside the connection block. A knocking block is fixed to the outer wall of the rotating rod. A hinged block is slidably installed on the top of the knocking block. A connecting rod is hinged to the top of the hinged block, and the top of the connecting rod is fixed to the bottom of the fixing plate. When the fixing plate moves downward, the connecting rod can move downward, causing the connecting rod to squeeze the hinged block, making the hinged block squeeze the knocking block to rotate, and making the knocking block knock on the outer wall of the connection cover.

The humidity sensor is electrically connected to the controller.

[0013] According to the above technical solution, a shielding plate is hinged to the side wall of the connection cover. An electric telescopic rod is fixed to the side wall of the cabinet body. The electric telescopic rod is electrically connected to the controller. The output end of the electric telescopic rod is fixed with an L-shaped sliding rod. The outer wall of the L-shaped sliding rod is attached to the inner side of the side wall of the shielding plate. When the humidity in the electrical cabinet exceeds 60%, the humidity sensor will be induced by the humidity and transmit an electrical signal to the controller. The controller will transmit the signal to the electric telescopic rod, causing the electric telescopic rod to start, driving the L-shaped sliding rod to approach the cabinet body, and the L-shaped sliding rod to pull the shielding plate to block the mesh holes on the right side of the connection cover.

[0014] According to the above technical solution, a shielding plate is hinged to the side wall of the connection cover. A pushing block penetrates through the side wall of the cabinet body and is slidably connected at the penetration point. A moving frame is fixed to the side wall of the pushing block. A return spring is fixed to the side wall of the moving frame, and the side of the return spring away from the moving frame is fixed to the inner wall of the cabinet body. A protective cover is slidably installed on the front of the electrical equipment. A hinged rod is hinged to the outer wall of the protective cover, and the end of the hinged rod away from the protective cover is hinged to the moving frame. When the shielding plate rotates in reverse, the shielding plate will squeeze the pushing block, causing the pushing block to move into the cabinet body. Thus, the pushing block drives the moving frame to move. The moving frame squeezes the hinged rod, causing the hinged rod to rotate at the hinge point. Thus, the hinged rod can squeeze the protective cover to move, and the protective cover shields the wire harness connection part of the electrical equipment.

[0015] The present invention provides an electrical cabinet with a dehumidification function, having the following beneficial effects:

[0016] 1. In the present invention, when the condensation pipe is used for a long time, by pushing the L-shaped slider to move, the L-shaped slider can drive the moving column to move, enabling the extrusion rod to move in the spiral groove, driving the rotating sleeve to rotate, and making the scraping plate rotate along the outer wall of the condensation pipe. The scraping plate can scrape off deposits such as scale attached to the outer wall of the condensation pipe, improving the condensation effect of the condensation pipe, facilitating subsequent drying of moisture. Moreover, through the cooperation of the steel rope and the push plate, when the rotating sleeve rotates, the steel rope can be wound up, and the steel rope can pull the push plate to move along the inner wall of the connecting cover, thereby pushing water droplets and the like on the inner wall of the connecting cover to the discharge hole at the bottom of the connecting cover for discharge, preventing a large amount of water droplets from adhering to the vicinity of the air inlet hole of the connecting cover, which may easily cause the water droplets to enter the cabinet through the air inlet hole and damage the electrical equipment.

[0017] 2. In the present invention, when the push plate moves, it can drive the connecting rod to move, enabling the extrusion block to extrude a plurality of transmission blocks. Through the cooperation of the fixing plate, the connecting rod, the hinge block, and the return spring, the knocking block can knock back and forth on the bottom of the connecting cover, causing the connecting cover to vibrate, and the vibration is transmitted to the condensation pipe. When the scraping plate scrapes off deposits such as scale attached to the outer wall of the condensation pipe, the vibration of the condensation pipe can accelerate the falling of deposits such as scale on the condensation pipe, improving the cleaning efficiency of the condensation pipe.

[0018] 3. In the present invention, when the condensation effect of the condensation pipe decreases, a large amount of moisture will enter the cabinet, causing the moisture to contact the humidity sensor. When the humidity sensor senses the humidity, it can transmit an electrical signal to the controller, causing the controller to control the electric telescopic rod to start. Thus, the electric telescopic rod can drive the L-shaped sliding rod to move, enabling the L-shaped sliding rod to squeeze the shielding plate to reverse, blocking the mesh holes on the right side of the connecting cover, and stopping the moisture from entering the cabinet, preventing excessive moisture from entering and damaging the electrical equipment. Moreover, through the cooperation of the push block, the moving frame, and the hinge rod, the two protective covers can approach each other, shielding the wire harness connection part of the electrical equipment and preventing the wire harness connection part from contacting a large amount of moisture, which may cause a short-circuit phenomenon.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 9, an embodiment of the present invention is: an electrical cabinet with a dehumidification function, including a cabinet body 1, a top plate 2 is fixed on the top of the cabinet body 1, an electrical device 4 is fixed inside the cabinet body 1, an air inlet hole 11 is opened on the right side of the cabinet body 1, an air suction fan 3 is fixed on the left side of the cabinet body 1, the air suction pipe of the air suction fan 3 is communicated with the inside of the cabinet body 1, a controller 12 is fixed on the front of the cabinet body 1, a connection cover 5 is fixed on the right side of the cabinet body 1, a cold air meter 6 is fixed on the outer wall of the connection cover 5, a condensation pipe 7 is fixed on the inner wall of the connection cover 5, the cold air meter 6 is fixedly connected to the condensation pipe 7 through a pipeline. By starting the cold air meter 6, cold air can enter the condensation pipe 7 through the pipeline, improving the refrigeration effect of the condensation pipe 7. A scraping component for improving the condensation effect is provided on the connection cover 5; wherein, the scraping component includes an L-shaped slider 81, a connection spring 82, a moving column 83, a pressing rod 86, a rotating sleeve 84, a spiral groove 85, a scraping plate 87, a steel wire rope 88, a pushing plate 89 and a reset spring 810; the L-shaped slider 81 is slidably installed on the outer wall of the connection cover 5, a connection spring 82 is fixed on the side wall of the L-shaped slider 81, and the side of the connection spring 82 away from the L-shaped slider 81 is fixed on the inner wall of the connection cover 5. A rotating sleeve 84 penetrates through the side wall of the connection cover 5 and is rotatably connected at the penetration point. A spiral groove 85 is opened on the outer wall of the rotating sleeve 84. A moving column 83 is fixed on the side of the L-shaped slider 81 close to the connection cover 5. A pressing rod 86 is fixed on the outer wall of the moving column 83. The pressing rod 86 penetrates through the spiral groove 85 and fits at the penetration point. A pushing plate 89 is slidably installed on the inner wall of the connection cover 5. A reset spring 810 is fixed on the side wall of the pushing plate 89, and the side of the reset spring 810 away from the pushing plate 89 is fixed on the inner side of the inside of the connection cover 5. A winding groove is opened on the outer wall of the rotating sleeve 84, and a steel wire rope 88 is fixed on the inner wall of the winding groove. One end of the steel wire rope 88 away from the rotating sleeve 84 is fixed on the pushing plate 89.

[0031] By providing the spiral groove 85, when the pressing rod 86 moves in the spiral groove 85, it can squeeze the spiral groove 85, enabling the rotating sleeve 84 to rotate. The outer wall of the scraping plate 87 fits against the outer wall of the condensation pipe 7. By the rotation of the rotating sleeve 84, the scraping plate 87 can be driven to rotate, causing the scraping plate 87 to rotate while fitting against the outer wall of the condensation pipe 7, so that the scraping plate 87 can scrape off deposits such as scale attached to the outer wall of the condensation pipe 7, preventing a large amount of deposits such as scale from adhering to the outer wall of the condensation pipe 7 and blocking the outer wall of the condensation pipe 7, which would affect the condensation effect of the condensation pipe 7.

[0032] The outer wall size of the push plate 89 matches the inner wall size of the connecting cover 5. The four faces of the push plate 89 are closely attached to the four faces of the connecting cover 5. When the rotating sleeve 84 rotates, it can wind up the steel rope 88, so that the steel rope 88 can pull the push plate 89 to move, making the push plate 89 move along the inner wall of the connecting cover 5, thereby pushing the water droplets and the like on the inner wall of the connecting cover 5 to the discharge hole at the bottom of the connecting cover 5 for discharge, preventing a large amount of water droplets from adhering to the connecting cover 5 near the air inlet hole 11, which is likely to cause the water droplets to enter the cabinet body 1 through the air inlet hole 11 and damage the electrical equipment 4.

[0033] During the operation of this embodiment: When the condenser tube 7 is used for a long time and a large amount of deposits such as scale adhere to the outer wall of the condenser tube 7, resulting in a reduction in the condensation effect of the condenser tube 7, by pushing the L-shaped slider 81 towards the connecting cover 5, the connecting spring 82 is compressed. And when the L-shaped slider 81 moves towards the connecting cover 5, it drives the moving column 83 to move in the rotating sleeve 84, so that the moving column 83 can drive the extrusion rod 86 to move in the spiral groove 85, making the extrusion rod 86 move the spiral groove 85, causing the spiral groove 85 to be under extrusion force and making the rotating sleeve 84 rotate. When the rotating sleeve 84 rotates, the scraper 87 can rotate while adhering to the outer wall of the condenser tube 7. The deposits such as scale adhering to the outer wall of the condenser tube 7 can be scraped off and dropped by the scraper 87. And when the rotating sleeve 84 rotates, the winding groove opened on the rotating sleeve 84 can wind up the steel rope 88, so that the steel rope 88 pulls the push plate 89 away from the cabinet body 1, thereby pushing the water droplets and the like on the inner wall of the connecting cover 5 to the discharge hole at the bottom of the connecting cover 5 for discharge. And when the push plate 89 moves away from the cabinet body 1, the push plate 89 will compress the return spring 810.

[0034] When the L-shaped slider 81 is released, since the connecting spring 82 is in a compressed state, the connecting spring 82 can drive the L-shaped slider 81 to reset, making the L-shaped slider 81 drive the moving column 83 to move out of the rotating sleeve 84, so that the rotating sleeve 84 can drive the scraper 87 to rotate and reset, and the steel rope 88 on the rotating sleeve 84 is loosened. Since the return spring 810 is in a compressed state, the return spring 810 can drive the push plate 89 to reset. By squeezing the L-shaped slider 81 back and forth, the scraper 87 rotates back and forth to scrape the outer wall of the condenser tube 7.

[0035] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, it further includes a knocking component and an auxiliary component for knocking the outer wall of the connecting cover 5. The knocking component includes a connecting rod 91, a pressing block 93, a support plate 92, a fixing plate 95, a transmission block 94, a transmission spring 96, a connecting rod 911, a hinge block 910, a knocking block 99, a connecting block 97 and a rotating rod 98. One end of the connecting rod 91 is fixed on the push plate 89, and the other end of the connecting rod 91 is fixed with a pressing block 93. A support plate 92 is fixed on the outer wall of the connecting cover 5. A transmission block 94 penetrates through the support plate 92. The bottom of the transmission block 94 is fixed with a fixing plate 95. The top of the fixing plate 95 is fixed with a transmission spring 96. The top of the transmission spring 96 is fixed to the bottom of the support plate 92. A connecting block 97 is fixed to the bottom of the connecting cover 5. A rotating rod 98 is rotatably installed inside the connecting block 97. A knocking block 99 is fixed on the outer wall of the rotating rod 98. A hinge block 910 is slidably installed on the top of the knocking block 99. The top of the hinge block 910 is hinged with a connecting rod 911. The top of the connecting rod 911 is fixed to the bottom of the fixing plate 95.

[0036] Multiple groups of knocking blocks 99 are provided, and the multiple groups of knocking blocks 99 are arranged in a linear array at the bottom of the connecting cover 5. Through the arrangement of the multiple groups of knocking blocks 99, when the knocking blocks 99 knock back and forth at the bottom of the connecting cover 5, the connecting cover 5 can be vibrated, and the vibration is transmitted to the condensing pipe 7. When the scraper 87 scrapes the scale and other deposits attached to the outer wall of the condensing pipe 7, the vibration of the condensing pipe 7 can accelerate the falling of the scale and other deposits on the condensing pipe 7, improving the cleaning efficiency of the condensing pipe 7.

[0037] The auxiliary component includes a guide plate 101, a humidity sensor 102, a shielding plate 103, an electric telescopic rod 104, an L-shaped sliding rod 105, a pushing block 106, a moving frame 107, a hinge rod 109, a protective cover 108 and a return spring 1010; a guide plate 101 is fixed on the inner wall of the cabinet body 1. A humidity sensor 102 is fixed inside the guide plate 101. The humidity sensor 102 is electrically connected to the controller 12. A shielding plate 103 is hinged on the side wall of the connecting cover 5. An electric telescopic rod 104 is fixed on the side wall of the cabinet body 1. The electric telescopic rod 104 is electrically connected to the controller 12. The output end of the electric telescopic rod 104 is fixed with an L-shaped sliding rod 105. The outer wall of the L-shaped sliding rod 105 is attached to the inner side of the side wall of the shielding plate 103. A shielding plate 103 is hinged on the side wall of the connecting cover 5. A pushing block 106 penetrates through the side wall of the cabinet body 1 and is slidably connected at the penetration. A moving frame 107 is fixed on the side wall of the pushing block 106. A return spring 1010 is fixed on the side wall of the moving frame 107. The side of the return spring 1010 away from the moving frame 107 is fixed on the inner wall of the cabinet body 1. A protective cover 108 is slidably installed on the front surface of the electrical equipment 4. A hinge rod 109 is hinged on the outer wall of the protective cover 108. One end of the hinge rod 109 away from the protective cover 108 is hinged on the moving frame 107.

[0038] The humidity sensor 102 is electrically connected to the controller 12. When the condensation effect on the condensing pipe 7 decreases, a large amount of moisture will enter the cabinet 1, causing the moisture to come into contact with the humidity sensor 102. When the humidity sensor 102 senses the humidity, it can transmit an electrical signal to the controller 12, causing the controller 12 to control the electric telescopic rod 104 to start. Thus, the electric telescopic rod 104 can drive the L-shaped sliding rod 105 to move, enabling the L-shaped sliding rod 105 to squeeze the shielding plate 103 to reverse, so that the shielding plate 103 blocks the mesh holes on the right side of the connecting cover 5, stopping the moisture from entering the cabinet 1 and preventing excessive moisture from entering and damaging the electrical equipment 4. Moreover, through the cooperation of the push block 106, the moving frame 107 and the hinge rod 109, the two protective covers 108 can approach each other, shielding the wire harness connection points of the electrical equipment 4 and preventing the wire harness connection points from coming into contact with a large amount of moisture, which may cause a short-circuit phenomenon.

[0039] During the operation of this embodiment: When the push plate 89 moves away from the cabinet 1, it will cause the push plate 89 to drive the connecting rod 91 to move, causing the connecting rod 91 to drive the extrusion block 93 to move, and the arc surface at the bottom of the extrusion block 93 to come into contact with the top arc surface of the transmission block 94. When the extrusion block 93 contacts the top of the transmission block 94, the transmission block 94 will move downward under the extrusion force, causing the transmission block 94 to drive the fixed plate 95 to move downward, stretching the transmission spring 96. When the fixed plate 95 moves downward, it will cause the fixed plate 95 to drive the connecting rod 911 to move downward, causing the connecting rod 911 to squeeze the hinge block 910, enabling the hinge block 910 to move in the top chute of the knocking block 99, and causing the hinge block 910 to squeeze the knocking point of the knocking block 99 to move upward. Thus, the rotating rod 98 rotates on the connecting block 97. When the knocking block 99 rotates upward, the knocking block 99 can knock on the bottom of the connecting cover 5. And when the extrusion block 93 moves between the two transmission blocks 94, since the transmission spring 96 is in a stretched state, the transmission spring 96 can drive the fixed plate 95 to reset upward. And when the fixed plate 95 moves upward, it will cause the connecting rod 911 to pull the hinge block 910, so that the hinge block 910 can pull the knocking block 99 to reset for the next knocking operation.

[0040] Moreover, when a large amount of scale and other deposits adhere to the outer wall of the condenser tube 7, the condensation effect of the condenser tube 7 will be reduced. When the humidity on the outer wall of the cabinet body 1 is too high, the condensation effect of the condenser tube 7 on the humidity will be poor, resulting in a large amount of humidity entering the cabinet body 1. The humidity will pass through the guide plate 101 and then pass by the humidity sensor 102. Since the suitable humidity range inside the cabinet body 1 is 40%-60%, when the humidity is too high and exceeds 60%, the humidity sensor 102 will sense the corresponding humidity, and thus the humidity sensor 102 will transmit an electrical signal to the controller 12. After receiving the signal, the controller 12 controls the electric telescopic rod 104 to start, causing the electric telescopic rod 104 to drive the L-shaped sliding rod 105 to approach the cabinet body 1. The L-shaped sliding rod 105 moves inside the side wall of the shielding plate 103, and the L-shaped sliding rod 105 pulls the shielding plate 103 to rotate towards the connecting cover 5. The shielding plate 103 blocks the mesh holes on the right side of the connecting cover 5, thereby preventing the humidity from continuing to enter the cabinet body 1. Moreover, when the shielding plate 103 rotates towards the connecting cover 5, the shielding plate 103 will squeeze the push block 106, causing the push block 106 to move into the cabinet body 1. The push block 106 drives the moving frame 107 to move, stretching the return spring 1010. When the moving frame 107 moves, it will squeeze the hinge rod 109, causing the hinge rod 109 to rotate at the hinge, enabling the hinge rod 109 to squeeze the two protective covers 108 to approach each other. The protective covers 108 can shield and protect the wire harness connection points of the electrical equipment 4. And at this time, the staff can process the surface of the condenser tube 7 for the next drying operation. And through the controller 12, when controlling the electric telescopic rod 104 to drive the L-shaped sliding rod 105 away from the cabinet body 1, the L-shaped sliding rod 105 will squeeze the shielding plate 103 to unfold, so that the shielding plate 103 no longer blocks the mesh holes on the right side of the connecting cover 5, thus enabling the air intake and heat dissipation operation. And when the shielding plate 103 is reset, since the push block 106 is no longer under the extrusion force and the return spring 1010 is in the stretched state, the return spring 1010 drives the moving frame 107 to reset. The moving frame 107 pulls the hinge rod 109, causing the hinge rod 109 to rotate at the hinge, and the hinge rod 109 pulls the two protective covers 108 to move away from each other, so that the wire harness connection points of the electrical equipment 4 are exposed for heat dissipation and for the maintenance, unplugging and plugging of the wire harness connection points.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
