Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet with a drying function. Background Art

[0002] Electrical cabinets are made of steel and are used to protect the normal operation of components. They are widely used in industrial production and residential electricity use. When electrical cabinets work in a humid and hot environment for a long time, a large amount of water vapor will accumulate inside to form condensation. Once the condensation adheres to the insulation surface, it will accelerate the deterioration of the insulating medium, causing the circuit breaker to trip or electrical equipment to be damaged. In more serious cases, it will cause major power accidents, so the inside of the electrical cabinet needs to be dried.

[0003] For example, an electrical cabinet with a drying function is disclosed in the announcement number CN116632681A. When in use, the desiccant is manually pushed so that the desiccant falls onto the third rotating plate, and then the opening and closing plate is closed downward. When the wind blown out of the bellows enters the air outlet pipe through the first air pipe, the desiccant can dry the wind to avoid bringing moisture into the electrical cabinet. When the desiccant absorbs enough water vapor, the weight of the desiccant increases, causing the third rotating plate to rotate downward, and the torsion spring is deformed. When the third rotating plate rotates downward, the second rotating plate is driven to rotate downward through the first connecting rod. At this time, the used desiccant on the third rotating plate is discharged from the air outlet pipe, and the unused desiccant in the storage box slides downward and then passes through the blocking plate. The blocking plate slows down the unused desiccant, thereby leaving enough time for the third rotating plate to reset. When the used desiccant is discharged, the torsion spring is reset. Under the reset action of the torsion spring, the third rotating plate is reset upward. The third rotating plate is reset upward and drives the second rotating plate to reset upward through the first connecting rod. At this time, the unused desiccant slides onto the third rotating plate, thereby realizing automatic replacement of the desiccant.

[0004] Most of the desiccants currently used are in granular form. After long-term use, the third rotating plate is folded under the gravity of the desiccant placed on the top thereof, causing the desiccant to fall and be discharged from the air outlet pipe, and at the same time, the desiccant in the storage box slides downward. In this process, it cannot be guaranteed that the desiccant can fill the air outlet pipe 82, which will result in the gas entering the electrical cabinet not being effectively dried, and unused desiccant will fall along with the used desiccant, causing waste. The overall drying structure inside the electrical cabinet is complicated, which is not conducive to production. Summary of the invention

[0005] The object of the present invention is to provide an electrical cabinet with a drying function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: an electrical cabinet with a drying function, comprising a cabinet body; A heat dissipation mechanism disposed inside and on the right side of the cabinet; An air outlet is provided on the left side of the cabinet; and a drying component arranged on the heat dissipation mechanism; The heat dissipation mechanism is used to dissipate heat inside the cabinet, and the drying component is used to dry the gas entering the cabinet; The heat dissipation mechanism is composed of a heat dissipation fan and an air inlet hood. The drying component is arranged on the air inlet hood. Replacement components are arranged inside the air inlet hood and on the drying component. The replacement components are used to replace the drying component. The gas drawn into the cabinet by the heat dissipation mechanism is dried by the drying component to prevent moisture in the air from entering the cabinet. After long-term use, the replacement component can automatically replace the drying box in the drying component used for drying the gas, which is easy to use.

[0007] Preferably, the cooling fan is arranged inside the cabinet, and the cooling fan draws air into the cabinet through an air inlet hood, and the air inlet hood is composed of a hood and a filter, and the filter is fixed inside the hood to isolate dust, and the hood passes through the right side of the cabinet and is fixed to the cabinet by bolts. The cooling fan draws external air into the cabinet through the hood, and the air entering the cabinet is filtered by the set filter. The air enters the cabinet to dissipate heat for electrical components inside the cabinet, thereby ensuring the normal operation of the cabinet.

[0008] Preferably, the drying component includes a placement rack, the placement rack is fixed on the top of the cover body, a telescopic rod is fixed to the inner wall of the placement rack, a resistance plate is fixed to the end of the telescopic rod away from the placement rack, an extrusion spring is fixed to the side of the resistance plate close to the telescopic rod, and the end of the extrusion spring away from the resistance plate is fixed to the inner wall of the placement rack, and a drying box is placed inside the placement rack, and the gas entering the cabinet can be dried by the arranged drying box.

By placing the drying box in the placement rack, when the drying box falls into the cover body, the gas entering the cover body needs to first pass through the drying box and then enter the cabinet body, and the moisture in the air is adsorbed by the desiccant on the inner side of the inner shell, thereby achieving a drying effect.

[0010] Preferably, the sides of the inner shell and the outer shell are provided with air holes for air flow to pass through, so that the desiccant can adsorb moisture in the gas.

When the desiccant continues to fall, the limiting rod can contact the inner side of the limiting groove, thereby limiting the outer shell, and at the same time, under the elastic action of the spring piece, the outer shell and the inner wall of the cover body are kept in a state of being in contact. With long-term use, too much moisture is adsorbed on the desiccant, resulting in an increase in the overall weight of the inner shell and the desiccant. The inner shell moves downward for a certain distance, and the inner shell moves downward with the fixing rod and the contact block. The contact wheel is set so that when the inner shell moves downward, the contact wheel rotates, which will not provide too much resistance to the inner shell and affect the normal downward movement of the inner shell. When the contact block moves to the limit When the gear is in the position of the positioning groove, under the action of the connecting spring, the resistance block moves the resistance wheel to the left, and the resistance wheel pushes the limit rod, so that the limit rod moves to the left and withdraws from the limit groove, thereby releasing the limit on the shell, and the shell can move downward under the action of its own gravity. When the shell moves to the position of the gear, the rack fixed on the left side of the shell and the gear enter into a meshing state. As the shell moves downward with the rack, the gear can be driven to rotate, and the gear drives the rotating wheel to rotate through the conveyor belt. When the rotating wheel rotates, the push rod resists the push block, causing the push block to move upward.

[0012] Preferably, an inclined groove is provided at the bottom of the shell, and when the pushing block moves upward, the pushing block can abut against the inclined groove at the bottom of the shell, thereby pushing the shell to move leftward, causing a force to move leftward on the abutment plate, and no longer squeezing the rightmost drying box, so that the rightmost drying box can move downward under the action of its own gravity and fall into the cover body.

[0013] Preferably, both the top of the cover body and the bottom of the placement rack are provided with openings, and a guide tube is fixed to the bottom of the cover body.

The drying box can fall into the cover body through the openings at the bottom of the placement rack and the top of the cover body, and the top of the placement rack is set to an open state, thereby facilitating the staff to place the drying box into the placement rack.

[0014] Preferably, a reminder mechanism is provided on the top and inside of the placement rack, and the reminder mechanism includes a reminder rod, which passes through the top of the placement rack and is slidably connected to the placement rack. A spring is fixed to the inner wall of the placement rack, and one end of the spring away from the placement rack is fixed to the reminder rod. When the contact plate moves a certain distance to the right, the contact plate can contact the bottom of the reminder rod, pushing the reminder rod to move upward, thereby reminding the staff to add a drying box inside the placement rack.

[0015] Compared with the prior art, the present invention provides an electrical cabinet with a drying function, which has the following beneficial effects: 1. The electrical cabinet with drying function is provided with drying components and replacement components. With long-term use, the desiccant absorbs too much moisture, resulting in an increase in the overall weight of the inner shell and the desiccant.

When the outer shell moves to the position of the gear, it drives the gear to rotate, thereby controlling the rotation of the rotating wheel, and the push rod abuts the push block, so that the push block moves upward. The push block can abut on the inclined groove at the bottom of the outer shell, thereby pushing the outer shell to move to the left, and no longer squeezes the rightmost drying box, so that the rightmost drying box can move downward under the action of its own gravity and fall into the cover body, completing the replacement.

[0016] 2. For the electrical cabinet with drying function, when the drying box falls from the cover, it can fall into the guide tube. The drying box can be taken out by opening the guide tube, and the desiccant in the inner shell can be replaced before continuing to use.

The air enters the cabinet 1 to dissipate heat for the electrical components inside the cabinet 1, thereby ensuring the normal operation of the cabinet 1.

[0022] The drying component 3 includes a placement rack 31, which is fixed on the top of the cover body 221. A telescopic rod 32 is fixed to the inner wall of the placement rack 31. A resistance plate 33 is fixed to the end of the telescopic rod 32 away from the placement rack 31. An extrusion spring 34 is fixed to the side of the resistance plate 33 close to the telescopic rod 32. The end of the extrusion spring 34 away from the resistance plate 33 is fixed to the inner wall of the placement rack 31. A drying box 35 is placed inside the placement rack 31. The gas entering the cabinet 1 can be dried by the provided drying box 35.

[0023] The drying box 35 includes an outer shell 351, an inner shell 352, a desiccant 353 and a rubber rope 354. An openable door is provided at the bottom of the outer shell 351. A rubber rope 354 is fixed on the inner wall of the outer shell 351. One end of the rubber rope 354 away from the outer shell 351 is fixed to the top of the inner shell 352. The inner shell 352 is plugged into the outer shell 351. The desiccant 353 is placed on the inner side of the inner shell 352. By placing the drying box 35 in the placement rack 31, when the drying box 35 falls into the cover body 221, the gas entering the cover body 221 needs to first pass through the drying box 35 and then enter the cabinet 1. The moisture in the air is adsorbed by the desiccant 353 on the inner side of the inner shell 352, thereby achieving a drying effect.

[0024] The sides of the inner shell 352 and the outer shell 351 are provided with air holes for air flow to pass through, so that the desiccant 353 can absorb moisture in the gas.

[0025] The replacement component 4 includes a fixed column 41, the bottom of which is fixed on the inner wall of the cover body 221, a spring sheet 42 is fixed on the right side of the fixed column 41, the fixed column 41 is penetrated by a limit rod 43 and is slidably connected to the limit rod 43, a return spring 44 is fixed on the left side of the fixed column 41, and the end of the return spring 44 away from the fixed column 41 is fixed to the limit rod 43, the fixed column 41 is penetrated by a gear 45 and is rotatably connected to the gear 45, the gear 45 is transmission-connected to a rotating wheel 46 through a transmission belt, the rotating wheel 46 is rotatably installed on the inner wall of the cover body 221, a push rod 47 is fixed on the surface of the rotating wheel 46, the bottom of the placement rack 31 is penetrated by a push block 48 and is slidably connected to the push block 48, and the left side of the inner shell 352 is fixed There is a fixing rod 49, the fixing rod 49 passes through the resistance block 410 and is slidably connected with the resistance block 410, and the resistance block 410 is rotatably installed with a resistance wheel 411 at one end away from the fixing rod 49, and a connecting spring 412 is fixed to the side of the resistance block 410 close to the fixing rod 49, and the end of the connecting spring 412 away from the resistance block 410 is fixed to the left side of the inner shell 352, and a rack 413 is fixed to the left side of the outer shell 351, and a limiting groove 414 is provided on the left side of the outer shell 351. When the drying box 35 falls into the cover body 221, the elastic sheet 42 is deformed by the gravity of the drying box 35 as a whole, and the limiting rod 43 is inserted into the limiting groove 414. As the outer shell 351 continues to fall, the limiting rod 43 can be in contact with the limiting groove 414. The inner side of the groove 414 is used to limit the outer shell 351, and at the same time, under the elastic action of the spring piece 42, the outer shell 351 is kept in contact with the inner wall of the cover body 221. With long-term use, too much moisture is adsorbed on the desiccant 353, resulting in an increase in the overall weight of the inner shell 352 and the desiccant 353. The inner shell 352 moves downward for a certain distance, and the inner shell 352 moves downward with the fixing rod 49 and the abutment block 410. The abutment wheel 411 is set so that when the inner shell 352 moves downward, the abutment wheel 411 rotates, which will not provide too much resistance to the inner shell 352, affecting the normal downward movement of the inner shell 352. When the abutment block 410 moves to the position of the limiting groove 414, the inner shell 352 is connected. Under the action of the connecting spring 412, the resistance block 410 moves to the left with the resistance wheel 411, and the resistance wheel 411 pushes on the limiting rod 43, so that the limiting rod 43 moves to the left and withdraws from the limiting groove 414, thereby releasing the limit on the shell 351, and the shell 351 can move downward under the action of its own gravity. When the shell 351 moves to the position of the gear 45, the rack 413 fixed on the left side of the shell 351 enters into a meshing state with the gear 45. As the shell 351 moves downward with the rack 413, the gear 45 can be driven to rotate. The gear 45 drives the rotating wheel 46 to rotate through the conveyor belt. When the rotating wheel 46 rotates, it resists the pushing block 48 through the push rod 47, so that the pushing block 48 moves upward.

[0026] An inclined groove 6 is provided at the bottom of the shell 351. Through the inclined groove 6 provided at the bottom of the shell 351, when the push block 48 moves upward, the push block 48 can abut against the inclined groove 6 at the bottom of the shell 351, thereby pushing the shell 351 to move leftward, causing a force to move leftward on the abutment plate 33, and no longer squeezing the rightmost drying box 35, so that the rightmost drying box 35 can move downward under the action of its own gravity and fall into the cover body 221.

[0027] The top of the cover body 221 and the bottom of the placement rack 31 are both provided with openings, and a guide tube 10 is fixed to the bottom of the cover body 221. When the drying box 35 falls from the cover body 221, it can fall into the guide tube 10. The drying box 35 can be taken out by opening the guide tube 10, and the desiccant 353 in the inner shell 352 can be replaced before continuing to use it. The drying box 35 can fall into the cover body 221 through the openings at the bottom of the placement rack 31 and the top of the cover body 221, and the top of the placement rack 31 is set to an open state, so that the staff can place the drying box 35 in the placement rack 31 conveniently.

[0028] A reminder mechanism 5 is provided on the top and inside of the placement rack 31, and the reminder mechanism 5 includes a reminder rod 51, which passes through the top of the placement rack 31 and is slidably connected to the placement rack 31. A spring 52 is fixed on the inner wall of the placement rack 31, and the end of the spring 52 away from the placement rack 31 is fixed to the reminder rod 51. When the contact plate 33 moves a certain distance to the right, the contact plate 33 can contact the bottom of the reminder rod 51, pushing the reminder rod 51 to move upward, thereby reminding the staff to add a drying box 35 inside the placement rack 31.

[0029] Based on the above implementation, when the cabinet 1 is working, the cooling fan 21 works together, and the cooling fan 21 draws air into the cabinet 1 through the air inlet cover 22, and then discharges it through the air outlet on the left side of the cabinet 1, thereby achieving heat dissipation inside the cabinet 1.

[0030] When placing the drying box 35, first open the top of the placement rack 31 and place the drying box 35 into the placement rack 31. At this time, the drying box 35 needs to be pushed so that the drying box 35 falls into the cover body 221 through the opening at the top of the cover body 221. After the drying box 35 falls into the cover body 221, the elastic sheet 42 is deformed by the overall gravity of the drying box 35, and the limiting rod 43 is inserted into the limiting groove 414. As the shell 351 continues to fall, the limiting rod 43 can abut against the inner side of the limiting groove 414, thereby limiting the shell 351. At the same time, under the elastic action of the elastic sheet 42, the shell 351 and the inner wall of the cover body 221 are kept in a state of being in contact.

[0031] At this time, other drying boxes 35 are placed in the rack 31, and the abutment plate 33 is pressed to move the abutment plate 33 to the left until the drying boxes 35 are pressed against each other, so that the right side of the drying boxes 35 abuts against the inner wall of the rack 31, and the top of the rack 31 is closed.

[0032] With long-term use, too much moisture is absorbed on the desiccant 353, resulting in an increase in the overall weight of the inner shell 352 and the desiccant 353. The inner shell 352 moves downward a certain distance, and the inner shell 352 moves downward with the fixing rod 49 and the resistance block 410. The resistance wheel 411 is set so that when the inner shell 352 moves downward, the resistance wheel 411 rotates, which will not provide too much resistance to the inner shell 352 and affect the normal downward movement of the inner shell 352. When the resistance block 410 moves to the position of the limiting groove 414, under the action of the connecting spring 412, the resistance block 410 moves to the left with the resistance wheel 411, and the resistance wheel 411 pushes on the limiting rod 43, so that the limiting rod 43 moves to the left and withdraws from the limiting groove 414, thereby releasing the limit on the outer shell 351. The outer shell 351 It can move downward under the action of its own gravity. When the shell 351 moves to the position of the gear 45, the rack 413 fixed on the left side of the shell 351 enters into a meshing state with the gear 45. As the shell 351 moves downward with the rack 413, the gear 45 can be driven to rotate. The gear 45 drives the rotating wheel 46 to rotate through the conveyor belt. When the rotating wheel 46 rotates, the push rod 47 abuts against the pushing block 48, so that the pushing block 48 moves upward. When the pushing block 48 moves upward, the pushing block 48 can abut on the inclined groove 6 at the bottom of the shell 351, thereby pushing the shell 351 to move leftward, causing a force to move leftward on the abutment plate 33, and no longer squeezing the rightmost drying box 35, so that the rightmost drying box 35 can move downward under the action of its own gravity and fall into the cover body 221.

[0033] When the drying box 35 falls from the cover body 221, it can fall into the guide tube 10. The drying box 35 can be taken out by opening the guide tube 10, and the desiccant 353 in the inner shell 352 can be replaced for continued use.

[0034] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
