Description

Technical Field

[0001] The present invention belongs to the technical field of substations, and particularly relates to a heat dissipation protection device for electromechanical equipment. Background Art

[0002] A substation refers to a place in the power system where voltage and current are transformed, and electric energy is received and distributed. In a protection cabinet with a ventilation and heat dissipation function for a substation disclosed in the patent with the publication number CN218161419U, to ensure the continuous heat dissipation effect of the protection cabinet, "after the filter screen has been used for a long time, the filter screen can be replaced by pulling the handle." For the filter screen in this protection cabinet, it is necessary for personnel to judge whether replacement is needed, and during replacement, it requires manual replacement by personnel. The protection cabinet itself cannot monitor whether the filter screen needs to be replaced, and at the same time, it cannot replace the filter screen automatically when it is determined that replacement is needed, reducing the automation degree of the heat dissipation protection effect of the protection cabinet. Summary of the Invention

[0003] The purpose of the present invention is to provide a heat dissipation protection device for electromechanical equipment to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A heat dissipation protection device for electromechanical equipment includes a cabinet body. A cabinet door is hinged to the front side of the cabinet body. A fan is connected to the top of the cabinet body. A filtering module is provided on one side of the cabinet body. The filtering module includes an opening, a cylinder, an arc-shaped notch, and a filter screen. The openings are symmetrically arranged up and down on the side of the cabinet body close to the cabinet door. The wall of the cylinder is arranged in the opening. The arc-shaped notches are circumferentially arranged on the outer wall of the cylinder, and the arc-shaped notches are communicated with the inner cavity of the cylinder. The filter screen is arranged in the arc-shaped notches and is connected to the cylinder. A driving module is connected between the cylinder and the cabinet body. The driving module includes a communication notch, teeth, and a gear. The communication notches are symmetrically arranged up and down on the side wall of the cabinet body and are communicated with the openings. The teeth are circumferentially connected to one end of the outer wall of the cylinder far from the cabinet door, and the teeth pass through the communication notches and leave a gap with the cabinet body. The gear is arranged on one side of the cylinder and is meshed with the teeth.

[0005] Preferably, the filtering module further includes a first-stage baffle, a second-stage baffle, and an air inlet pipe. The first-stage baffles are symmetrically arranged inside one end of the cylinder close to the cabinet door and are both connected to the cabinet body, and the outer walls of the first-stage baffles are slidably matched with the cylinder. The second-stage baffles are symmetrically arranged inside one end of the cylinder far from the cabinet door and are both connected to the cabinet body, and the outer walls of the second-stage baffles are slidably matched with the cylinder. One end of the air inlet pipe is connected to the second-stage baffle, and the other end of the air inlet pipe is connected to the cabinet body, and the air inlet pipe is communicated with the inner cavity of the cylinder and the inner cavity of the cabinet body respectively to block the inner cavity of the cylinder so that the inner cavity of the cylinder is not easily connected to the outside.

[0006] Preferably, the filtering module further includes a plugging frame and a mounting bracket. The plugging frame is disposed between the cylinder and the cabinet door, and the plugging frame penetrates through the opening. The plugging frame is connected to the cabinet body by positioning bolts. The mounting bracket is connected to the side of the plugging frame away from the cabinet body. The cylinder is restricted by the plugging frame, so that the cylinder is not easily separated from the opening.

[0007] Preferably, the filtering module further includes a photoelectric emitter and a receiver. The photoelectric emitter is embedded in the mounting bracket. The receivers are circumferentially arrayed and embedded on the side of the cylinder close to the cabinet door, and the receivers correspond to the photoelectric emitter. Multiple groups of receivers correspond to multiple groups of filter meshes one by one. Since multiple groups of receivers correspond to multiple groups of filter meshes one by one, the filter mesh corresponding to the original receiver is rotated to another position and covered by the outer baffle member, while the filter mesh corresponding to another receiver is rotated to the position originally occupied by the filter mesh corresponding to the original receiver, thereby completing the automatic replacement of the filter mesh.

[0008] Preferably, the filtering module further includes an outer baffle member and a first-level assembly plate member. The outer baffle members are symmetrically arranged above and below the outside of the cylinder, and the outer baffle members are in sliding fit with the cylinder. The first-level assembly plate member is connected to the side of the outer baffle member away from the cylinder, and both the first-level assembly plate member and the outer baffle member are in contact with the cabinet body. The first-level assembly plate member is connected to the cabinet body by positioning bolts. The outer baffle member covers and shields the filter mesh that is outside the cabinet body and is not in use.

[0009] Preferably, the filtering module further includes a first-level arc plate, a second-level arc plate, a first-level baffle, a second-level baffle, a third-level baffle and a second-level assembly plate member. The first-level baffle is disposed on the side of the cylinder away from the cabinet door. The second-level baffle and the third-level baffle are both sleeved on the outer wall of the cylinder, and the teeth are between the first-level baffle and the second-level baffle. The filter mesh is between the second-level baffle and the third-level baffle. The first-level arc plate is connected between the first-level baffle and the second-level baffle, and there is a gap between the first-level arc plate and the teeth. The second-level arc plate is connected between the second-level baffle and the third-level baffle. The second-level assembly plate members are symmetrically connected to both sides of the second-level arc plate, and the second-level assembly plate members are respectively connected to the second-level arc plate, the first-level baffle, the second-level baffle and the third-level baffle, and the second-level assembly plate member is connected to the cabinet body by positioning bolts. The settings of the first-level arc plate, the first-level baffle and the second-level baffle prevent impurities in the external environment from entering the cabinet through the communication slot. Through the second-level arc plate and the third-level baffle, the filter mesh in the cabinet is isolated to prevent the filter mesh from interacting with the objects in the cabinet.

[0010] Preferably, the filtering module further includes an inclined panel member and a gas flow sensor. The inclined panel member is symmetrically connected to one side of the outer wall of the cabinet up and down and is located inside the cylinder. The inclined panel member is slidably engaged with the inner wall of the cylinder. The end of the air inlet pipe away from the cabinet is connected to the cavity between the two inclined panel members, and the arc-shaped notch on the outer side of the cabinet is connected to the cavity between the two inclined panel members. The gas flow sensor is connected to one side of the lower inclined panel member. After the filter screen for filtering air is used for a certain period of time, it will be blocked. When blocked, the amount of air passing through the filter screen decreases, resulting in a decrease in the air flow rate between the two inclined baffle plates. The gas flow sensor monitors the situation. When the air flow rate decreases to the preset value of the gas flow sensor, the gas flow sensor transmits the data to the peripheral device terminal.

[0011] Preferably, the driving module further includes a fixing plate member, a driving motor and an output shaft. The fixing plate member is arranged on the side of the cylinder away from the cabinet door and is connected to the cabinet. The driving motor is connected to the side of the fixing plate member close to the cylinder through a positioning bolt, and the rear end of the output shaft is connected to the output end of the driving motor. The end of the output shaft away from the driving motor is connected to the middle of one side of the gear. There is a gap between the driving motor and the air inlet pipe. The driving motor drives the output shaft to rotate, thereby driving the gear to rotate. Since the gear is meshed with the teeth, the cylinder rotates with the gear under the action of the teeth.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention is in use, the gas flow sensor monitors the gas flow in the chamber between the two inclined panel members. When the filter screen put into use is severely blocked, the amount of gas entering the chamber between the two inclined panel members decreases. When the gas flow drops to the preset value of the gas flow sensor, the driving module drives the cylinder to rotate, and in cooperation with the photoelectric emitter and receiver, the new filter screen is rotated out with the cylinder to replace the old filter screen in the original position, thereby completing the automatic replacement of the filter screen and improving the degree of automation.

The filtering module 4 includes an opening 41, a cylinder 42, an arc-shaped notch 43 and a filter net 44. The openings 41 are symmetrically arranged up and down on the side of the cabinet body 1 close to the cabinet door 2. The wall of the cylinder 42 is arranged in the opening 41. The arc-shaped notches 43 are arranged in a circumferential array on the outer wall of the cylinder 42, and the arc-shaped notches 43 communicate with the inner cavity of the cylinder 42. The filter net 44 is arranged in the arc-shaped notch 43, and the filter net 44 is connected to the cylinder 42. A driving module 5 is connected between the cylinder 42 and the cabinet body 1.

The teeth 52 are connected in a circumferential array to one end of the outer wall of the cylinder 42 far from the cabinet door 2, and the teeth 52 pass through the communicating notch 51 and have a gap with the cabinet body 1. The gear 53 is arranged on one side of the cylinder 42, and the gear 53 is meshed and connected with the teeth 52.

[0026] Reference Figures 1 - 9 As shown in the figure, the filtering module 4 further includes a primary blocking plate 45, a secondary blocking plate 46 and an air inlet pipe 47. The primary blocking plates 45 are symmetrically arranged inside one end of the cylinder 42 close to the cabinet door 2, and the primary blocking plates 45 are all connected to the cabinet body 1, and the outer wall of the primary blocking plate 45 is in sliding fit with the cylinder 42. The secondary blocking plates 46 are symmetrically arranged inside one end of the cylinder 42 far from the cabinet door 2, and the secondary blocking plates 46 are all connected to the cabinet body 1, and the outer wall of the secondary blocking plate 46 is in sliding fit with the cylinder 42. One end of the air inlet pipe 47 is connected to the secondary blocking plate 46, and the other end of the air inlet pipe 47 is connected to the cabinet body 1, and the air inlet pipe 47 communicates with the inner cavity of the cylinder 42 and the inner cavity of the cabinet body 1 respectively to block the inner cavity of the cylinder 42 so that the inner cavity of the cylinder 42 is not easily connected to the outside.

[0027] Reference Figures 1 - 3 As shown in the figure, the filtering module 4 further includes a blocking frame 48 and a mounting bracket 49. The blocking frame 48 is arranged between the cylinder 42 and the cabinet door 2, and the blocking frame 48 penetrates through the opening 41. The blocking frame 48 is connected to the cabinet body 1 through a positioning bolt. The mounting bracket 49 is connected to the side of the blocking frame 48 far from the cabinet body 1. The cylinder 42 is restricted by the blocking frame 48 so that the cylinder 42 is not easily separated from the opening 41.

[0028] Reference Figures 1 - 8 and Figure 11As shown, the filtering module 4 further includes a photoelectric emitter 410 and a receiver 411. The photoelectric emitter 410 is embedded in the mounting bracket 49. The receivers 411 are arranged in a circumferential array and embedded on the side of the cylinder 42 close to the cabinet door 2, and the receivers 411 correspond to the photoelectric emitter 410. Multiple groups of receivers 411 correspond to multiple groups of filter meshes 44 one by one. Since multiple groups of receivers 411 correspond to multiple groups of filter meshes 44 one by one, the filter mesh 44 corresponding to the original receiver 411 is rotated to another position and covered and blocked by the outer baffle member 412, while the filter mesh 44 corresponding to another receiver 411 is rotated to the original position of the filter mesh 44 corresponding to the original receiver 411, thus completing the automatic replacement of the filter mesh 44.

[0029] Reference Figures 1 - 3 As shown, the filtering module 4 further includes an outer baffle member 412 and a first-level assembly plate member 413. The outer baffle member 412 is symmetrically arranged up and down on the outside of the cylinder 42, and the outer baffle member 412 is in sliding fit with the cylinder 42. The first-level assembly plate member 413 is connected to the side of the outer baffle member 412 away from the cylinder 42, and both the first-level assembly plate member 413 and the outer baffle member 412 are in contact with the cabinet body 1. The first-level assembly plate member 413 is connected to the cabinet body 1 through positioning bolts. The outer baffle member 412 covers and blocks the filter mesh 44 that is outside the cabinet body 1 and is not in use.

[0030] Reference Figures 5 - 7 As shown, the filtering module 4 further includes a first-level arc plate 414, a second-level arc plate 415, a first-level baffle 416, a second-level baffle 417, a third-level baffle 418 and a second-level assembly plate member 419. The first-level baffle 416 is arranged on the side of the cylinder 42 away from the cabinet door 2. The second-level baffle 417 and the third-level baffle 418 are both sleeved on the outer wall of the cylinder 42, and the tooth 52 is between the first-level baffle 416 and the second-level baffle 417. The filter mesh 44 is between the second-level baffle 417 and the third-level baffle 418. The first-level arc plate 414 is connected between the first-level baffle 416 and the second-level baffle 417, and there is a gap between the first-level arc plate 414 and the tooth 52. The second-level arc plate 415 is connected between the second-level baffle 417 and the third-level baffle 418. The second-level assembly plate member 419 is symmetrically connected to both sides of the second-level arc plate 415 up and down, and the second-level assembly plate member 419 is respectively connected to the second-level arc plate 415, the first-level baffle 416, the second-level baffle 417 and the third-level baffle 418, and the second-level assembly plate member 419 is connected to the cabinet body 1 through positioning bolts. The settings of the first-level arc plate 414, the first-level baffle 416 and the second-level baffle 417 prevent impurities in the external environment from entering the cabinet body 1 through the communication notch 51. Through the second-level arc plate 415 and the third-level baffle 418, the filter mesh 44 inside the cabinet body 1 is isolated to prevent the filter mesh 44 from interacting with the objects inside the cabinet body 1.

[0031] Reference Figure 8 andFigure 9 As shown, the filtering module 4 further includes an inclined panel member 420 and a gas flow sensor 421. The inclined panel member 420 is symmetrically connected to one side of the outer wall of the cabinet body 1 up and down, and the inclined panel member 420 is located inside the cylinder 42. The inclined panel member 420 is slidably engaged with the inner wall of the cylinder 42. One end of the air inlet pipe 47 away from the cabinet body 1 is communicated with the cavity between the two inclined panel members 420, and the arc-shaped notch 43 located outside the cabinet body 1 is communicated with the cavity between the two inclined panel members 420. The gas flow sensor 421 is connected to one side of the lower inclined panel member 420. After the filter screen 44 for filtering air is used for a certain period of time, it will be blocked. When blocked, the amount of air passing through the filter screen 44 decreases, so that the air flow rate between the two inclined baffles decreases. The gas flow sensor 421 monitors. When the air flow rate decreases to the preset value of the gas flow sensor 421, the gas flow sensor 421 transmits the data to the peripheral terminal.

[0032] Reference Figures 1 - 7 As shown, the driving module 5 further includes a fixing plate member 54, a driving motor 55 and an output shaft 56. The fixing plate member 54 is arranged on the side of the cylinder 42 away from the cabinet door 2, and the fixing plate member 54 is connected to the cabinet body 1. The driving motor 55 is connected to the side of the fixing plate member 54 close to the cylinder 42 by positioning bolts, and the rear end of the output shaft 56 is connected to the output end of the driving motor 55. One end of the output shaft 56 away from the driving motor 55 is connected to the middle of one side of the gear 53. There is a gap between the driving motor 55 and the air inlet pipe 47. The driving motor 55 drives the output shaft 56 to rotate, thereby driving the gear 53 to rotate. Since the gear 53 is meshed with the teeth 52, the cylinder 42 rotates with the gear 53 under the action of the teeth 52.

[0033] Working principle: The cylinder 42 is arranged on the side wall of the cabinet body 1 through the opening 41. When arranging, the side wall of the cabinet body 1 passes through between two adjacent sets of teeth 52, and the teeth 52 are engaged with the gear 53 to prevent the existence of the teeth 52 from affecting the arrangement of the cylinder 42. After the cylinder 42 is arranged, the plugging frame 48 is sleeved on the side wall of the cabinet body 1 through the opening 41, and positioning bolts are used to fix the plugging frame 48 to the cabinet body 1, so as to limit the cylinder 42 and prevent the cylinder 42 from disengaging from the opening 41. The primary assembly plate 413 is connected and fixed to the cabinet body 1 by using positioning bolts, so as to fix the two outer baffle plates 412 on the upper and lower sides of the outer wall of the cylinder 42, covering and plugging the filter screen 44 that is exposed outside the cabinet body 1 and not in use. The secondary assembly plate 419 is connected and fixed to the cabinet body 1 by using positioning bolts, so as to arrange the primary arc plate 414, the secondary arc plate 415, the primary baffle 416, the secondary baffle 417, and the tertiary baffle 418. The arrangement of the primary arc plate 414, the primary baffle 416, and the secondary baffle 417 prevents impurities in the external environment from entering the cabinet body 1 through the communication notch 51. Through the secondary arc plate 415 and the tertiary baffle 418, the filter screen 44 inside the cabinet body 1 is isolated to prevent the filter screen 44 from affecting the objects inside the cabinet body 1. When the equipment inside the cabinet body 1 is running, the fan 3 is turned on to extract and discharge the air inside the cabinet body 1. To ensure the air extraction effect of the fan 3, the air in the external environment enters between the two inclined panel parts 420 through the filter screen 44 on the outside of the cabinet body 1. The air filtered by the filter screen 44 in use enters the cabinet body 1 through the air inlet pipe, so as to realize the heat dissipation of the equipment. After the filter screen 44 for filtering air is used for a certain period of time, it will be blocked. During the blocking, the air volume passing through the filter screen 44 decreases, so that the air flow rate between the two inclined baffle plates decreases. The gas flow sensor 421 monitors. When the air flow rate decreases to the preset value of the gas flow sensor 421, the gas flow sensor 421 transmits the data to the peripheral device terminal. The peripheral device terminal receives the data and controls the driving motor 55, the photoelectric emitter 410, and the receiver 411 to turn on. The driving motor 55 drives the output shaft 56 to rotate, so as to drive the gear 53 to rotate. Since the gear 53 is meshed with the teeth 52, under the action of the teeth 52, the cylinder 42 rotates with the gear 53. The original receiver 411 corresponding to the photoelectric emitter 410 no longer corresponds to the photoelectric emitter 410 due to the rotation of the cylinder 42. As the cylinder 42 continues to rotate, another receiver 411 adjacent to the original receiver 411 will rotate with the cylinder 42 to a position corresponding to the photoelectric emitter 410. This another receiver 411 receives the signal emitted by the photoelectric emitter 410, and the another receiver 411 transmits the signal to the peripheral device terminal. The peripheral device terminal receives the signal and controls the driving motor 55, the photoelectric emitter 410, and the receiver 411 to turn off.Since multiple groups of receivers 411 correspond to multiple groups of filter meshes 44 one by one, the filter mesh 44 corresponding to the original receiver 411 is rotated to another position and covered and blocked by the outer baffle member 412, while the filter mesh 44 corresponding to another receiver 411 is rotated to the original position of the filter mesh 44 corresponding to the original receiver 411, thus completing the automatic replacement of the filter mesh 44. As the filter mesh 44 is continuously replaced, when the last filter mesh 44 is replaced, when the receiver 411 corresponding to the last filter mesh 44 transmits a signal to the peripheral terminal, the peripheral terminal receives the signal and records it. When the gas flow rate monitored by the gas flow sensor 421 drops to the preset value again, the gas flow sensor 421 transmits the data to the peripheral terminal. The peripheral terminal receives the data and performs a limit through the peripheral display device, reminding the personnel to disassemble the cylinder 42 and clean the filter meshes 44 uniformly, thereby extending the cycle for the personnel to clean the filter meshes 44.
