Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of security cabinets, in particular to an intelligent electrical security cabinet with a temperature monitoring and alarm function. Background Art
[0002] Electrical cabinets are made of steel and are used to protect components. They are generally made of hot-rolled steel and cold-rolled steel. Cold-rolled steel is softer than hot-rolled steel and is more suitable for electrical cabinets. They are widely used in the chemical industry, environmental protection industry, power systems, metallurgical systems, industry, nuclear power industry, fire safety monitoring, transportation, and more.
[0003] Existing electrical cabinets generally have vents on both sides for natural ventilation. Under normal circumstances, natural ventilation can meet the requirements of the distribution cabinet. However, after long-term use, dust is easily accumulated on the filter screen of the vent, causing the filter screen at the vent to be blocked, resulting in less outside air entering, and then the temperature in the cabinet continues to rise; its internal heat dissipation will be affected, and after long-term use, some dust will also adhere to the electrical components inside the electrical cabinet. The presence of this dust will cause corrosion to the electrical components and affect the service life of the electrical components. Summary of the Invention
[0004] The object of the present invention is to provide an intelligent electrical security cabinet with temperature monitoring and alarm functions to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] An intelligent electrical security cabinet with a temperature monitoring and alarm function comprises: a cabinet body, symmetrically provided with ventilation openings on the side walls of the cabinet body, and symmetrically provided with temperature difference generators on the inner walls of the cabinet body; a filter screen provided in the ventilation opening, the filter screen being used to filter external dust; a cleaning device connected to the filter screen, the cleaning device being used to clean dust off the filter screen; a cooling device provided at the bottom of the cabinet body, the cooling device being used to cool the interior of the cabinet body;
[0007] Outside air enters the cabinet through the vents. During the process of entering, the outside air encounters the obstruction of the filter. The filter blocks the dust and impurities contained in the outside air, preventing the dust from entering the cabinet with the outside air, causing dust to accumulate on the electrical components inside the cabinet, resulting in a decrease in the heat dissipation performance of the electrical components; when the dust filtered by the filter continues to increase, the dust will block the pores in the filter, resulting in less outside air entering, and then the temperature in the cabinet continues to rise. The temperature increase causes the thermoelectric generator to generate electricity, which is transmitted to the cleaning device, causing the cleaning device to clean the filter and remove the dust on the surface of the filter, thereby increasing the amount of outside air entering, and thus improving the heat dissipation efficiency in the cabinet, thereby ensuring the normal operation of the electrical components in the cabinet; during the process of the cleaning device cleaning the filter, the controller controls the cooling device to start, and the cooling device draws the air inside the cabinet to the outside, so that the high-temperature air inside the cabinet is discharged, thereby achieving cooling inside the cabinet.
[0008] Preferably, the cleaning device includes: a sliding cavity, the sliding cavity is opened at the upper end of the vent, an electromagnet is provided at the end of the sliding cavity, the electromagnet is electrically connected to the thermoelectric generator, a slider is slidably connected in the sliding cavity, and the slider and the electromagnet are connected by a spring; the side of the slider away from the spring is connected to a filter; one end of the filter is connected to the lower end surface of the vent, and a magnet is provided on the side of the slider close to the filter.
[0009] Preferably, a movable cavity is formed at the lower end of the vent, a cam is provided in the movable cavity, the cam is connected to a rotating shaft, the rotating shaft is rotatably connected to the cabinet, a motor is provided at the bottom of the cabinet, a side of the rotating shaft away from the cam engages with a bevel gear in the transmission motor through a bevel gear, a side of the cam close to the vent is provided with a striker, the striker is slidably connected to the movable cavity; a top column is provided at the end of the striker away from the cam; the top column passes through the airbag;
[0010] Preferably, the filter screen consists of an outer screen and an inner screen, a gap is provided between the outer screen and the inner screen; and a rubber column is provided in the gap between the outer screen and the inner screen.
[0011] Preferably, an air bag is provided on the side of the impact block away from the cam, and the air bag is provided with an air outlet and an air inlet, and both the air inlet and the air outlet are provided with a one-way valve; the air inlet passes through the cabinet body and is connected to the hollow structure between the external network and the internal network;
[0012] When the filter is blocked by dust, the amount of outside air entering is reduced, causing the temperature in the cabinet to rise. As the temperature rises, the thermoelectric generator generates electricity under the action of the temperature difference. The electricity is transmitted to the electromagnet through the circuit, so that the electromagnet is energized. The electromagnet generates magnetic force, which attracts the slider to move along the sliding cavity. At this time, the slider is attracted by the magnet, and the spring is gradually stretched under the attraction of the electromagnet. When the magnetic force generated by the electromagnet is greater than the magnetic force of the magnet, the slider detaches from the magnet and moves rapidly along the sliding cavity toward the electromagnet. During the movement of the slider, the filter is driven to move. Under the pulling force of the slider, the filter changes from a relaxed state to a tight state. The dust on the filter is ejected outward at the moment of tension, and some of the dust is cleaned from the surface of the filter. When the outer and inner nets are stretched from a relaxed state to a tight state under the action of the slider, the rubber column supports the outer and inner nets to prevent the outer net from colliding with the inner net, causing dust to enter the gap through the outer net.
[0013] When the electromagnet is energized, the controller controls the motor to start, and the driving shaft in the motor drives the bevel gear to rotate. The bevel gears mesh with each other, driving the rotating shaft to rotate. During the rotation of the rotating shaft, the cam is driven to rotate. The cam rotates and hits the impact block. The impact block is hit and moves to the side away from the cam along the active cavity. During the movement of the impact block, it contacts the airbag, and the impact block squeezes the airbag, so that the pressure in the airbag is greater than the external pressure. The gas in the airbag is then discharged outward through the one-way valve in the air outlet pipe, and the gas in the airbag enters the gap between the outer net and the inner net. The gas then moves from the middle to both sides, and the gas moves from the gap to the outer net, spraying out the dust blocked on the outer net from the inside to the outside, cleaning the dust on the outer net, increasing the amount of outside air entering, thereby improving the heat dissipation efficiency in the cabinet, thereby ensuring the normal operation of the electrical components in the cabinet;
[0014] When the impact block moves, it drives the top column to move, and the top column hits the cabinet body. The impact on the cabinet body causes the filter to vibrate. During the vibration of the filter, the dust attached to the filter surface is shaken off to prevent the dust from clogging the air holes in the filter, resulting in less outside air entering. This increases the amount of outside air entering, thereby improving the heat dissipation efficiency in the cabinet body, thereby ensuring the normal operation of the electrical components in the cabinet body.
[0015] As the temperature inside the cabinet gradually drops, the power generated by the thermoelectric generator decreases, causing the magnetic force generated by the electromagnet to decrease. The slider then moves under the elastic force of the spring, and moves toward the side close to the filter. During the movement of the slider, the filter is driven to move, and the filter changes from a taut state to a relaxed state.
[0016] Preferably, the cooling device includes: a cooling cavity, the cooling cavity is symmetrically arranged on both sides of the motor, a filter plate No. 1 is provided on the side of the cooling cavity close to the inside of the cabinet, an air outlet is provided on the side of the cooling cavity away from the motor, and a filter plate No. 2 is provided on the air outlet.
[0017] Preferably, a cooling fan is provided in the cooling chamber, the cooling fan is provided with a rotating shaft, a driving gear is provided on the rotating shaft, a driven gear is provided on the rotating shaft, and the driving gear meshes with the driven gear;
[0018] In the process of the driving shaft in the motor driving the rotating shaft to rotate, the rotating shaft drives the driving gear to rotate, the driving gear meshes with the transmission driven gear, the driven gear drives the rotating shaft to rotate, and the rotating shaft drives the cooling fan to rotate. The cooling fan rotates, so that the hot air in the cabinet is filtered by the No. 1 filter plate and then enters the cooling cavity. The hot air moves under the action of the cooling fan, and the hot air moves along the cooling cavity to the side away from the cabinet. In the process of moving the hot air, it encounters the No. 2 filter plate, and the No. 2 filter plate filters the hot air again, and finally discharged to the outside through the air outlet, realizing the cooling of the cabinet temperature, thereby ensuring the normal operation of the electrical components in the cabinet.
[0019] Preferably, a temperature sensor is provided on the top of the cabinet, an alarm is provided on the outer wall of the cabinet, and the temperature sensor is electrically connected to the alarm through a controller.
[0020] When the temperature inside the cabinet continues to rise, the temperature sensor converts the temperature signal inside the cabinet into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. If the temperature exceeds the preset temperature, the controller immediately controls the alarm to start, and the alarm immediately generates an audible and visual alarm to remind the staff to cool down the cabinet in time to avoid excessive temperature and spontaneous combustion of the security cabinet, thereby ensuring the normal operation of the electrical components in the cabinet.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. During the movement of the slider, the filter is driven to move. Under the pulling force of the slider, the filter changes from a relaxed state to a tight state. The dust on the filter is ejected outward at the moment of tension, and part of the dust is cleaned from the surface of the filter. When the outer and inner nets are stretched from a relaxed state to a tight state under the action of the slider, the rubber column supports the outer and inner nets to prevent the outer nets from colliding with the inner nets, causing dust to enter the gap through the outer net.
[0023] 2. The impact block squeezes the airbag, making the pressure inside the airbag greater than the external pressure. The gas in the airbag is then discharged outward through the one-way valve in the outlet pipe. The gas in the airbag enters the gap between the outer net and the inner net, and the gas then moves from the middle to both sides. The gas moves from the gap to the outer net, spraying out the dust blocking the outer net from the inside to the outside, cleaning the dust on the outer net, increasing the amount of outside air entering, and thereby improving the heat dissipation efficiency in the cabinet, thereby ensuring the normal operation of the electrical components in the cabinet.
[0024] 3. During the movement of the impact block, the impact block drives the top column to move, and the top column hits the cabinet body. The impact on the cabinet body causes the filter to shake. During the shaking of the filter, the dust attached to the surface of the filter is shaken off to prevent the dust from clogging the air holes in the filter, resulting in less outside air entering; thereby increasing the amount of outside air entering, thereby improving the heat dissipation efficiency in the cabinet body, thereby ensuring the normal operation of the electrical components in the cabinet body.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] An intelligent electrical security cabinet with a temperature monitoring and alarm function comprises: a cabinet 1, symmetrically provided with ventilation openings 11 on the side walls of the cabinet 1, and symmetrically provided with a thermoelectric generator 12 on the inner wall of the cabinet 1 (this is prior art, disclosed in publication number CN110535373A, "A Thermoelectric Generator"); a filter 2 is provided within the ventilation opening 11, and is used to filter external dust; a cleaning device 3 is connected to the filter 2, and is used to clean dust from the filter 2; a cooling device 4 is provided at the bottom of the cabinet 1, and is used to cool the interior of the cabinet 1;
[0039] The outside air enters the cabinet 1 through the vent 11. During the process of the outside air entering, it encounters the obstruction of the filter 2. The filter 2 blocks the dust and impurities contained in the outside air, preventing the dust from entering the cabinet 1 with the outside air, causing dust to accumulate on the electrical components inside the cabinet 1, resulting in a decrease in the heat dissipation performance of the electrical components; when the dust filtered by the filter 2 continues to increase, the dust blocks the pores in the filter 2, resulting in a small amount of outside air entering, and then the temperature in the cabinet 1 continues to rise. The temperature increase causes the thermoelectric generator 12 to generate electricity, and the electricity is transmitted to the cleaning device 3, so that the cleaning device 3 cleans the filter 2 and removes the dust on the surface of the filter 2, thereby increasing the amount of outside air entering; during the process of the cleaning device 3 cleaning the filter 2, the controller controls the cooling device 4 to start, and the cooling device 4 draws the air inside the cabinet 1 to the outside, so that the high-temperature air inside the cabinet 1 is discharged, thereby achieving cooling and cooling inside the cabinet 1.
[0040] As a specific embodiment of the present invention, the cleaning device 3 includes: a sliding cavity 31, the sliding cavity 31 is opened at the upper end of the vent 11, an electromagnet 32 is provided at the end of the sliding cavity 31, the electromagnet 32 is electrically connected to the thermoelectric generator 12, a slider 33 is slidably connected in the sliding cavity 31, and the slider 33 and the electromagnet 32 are connected by a spring; the side of the slider 33 away from the spring is connected to the filter 2; one end of the filter 2 is connected to the lower end surface of the vent 11, and the side of the slider 33 close to the filter 2 is provided with a magnet.
[0041] As a specific embodiment of the present invention, a movable cavity 34 is formed at the lower end of the vent 11, a cam 35 is provided in the movable cavity 34, the cam 35 is connected to a rotating shaft 36, the rotating shaft 36 is rotatably connected to the cabinet 1, a motor is provided at the bottom of the cabinet 1, the rotating shaft 36 is engaged with a bevel gear in the transmission motor through a bevel gear on the side away from the cam 35, a striker 37 is provided on the side of the cam 35 close to the vent 11, the striker 37 is slidably connected to the movable cavity 34; a top column is provided on the end of the striker 37 away from the cam 35; the top column passes through the airbag 38;
[0042] As a specific embodiment of the present invention, the filter screen 2 is composed of an outer screen 21 and an inner screen 22 , with a gap provided between the outer screen 21 and the inner screen 22 ; and a rubber column 23 is provided in the gap between the outer screen 21 and the inner screen 22 .
[0043] As a specific embodiment of the present invention, an air bag 38 is provided on the side of the impact block 37 away from the cam 35. The air bag 38 is provided with an air outlet and an air inlet. Both the air inlet and the air outlet are provided with a one-way valve; the air inlet passes through the cabinet 1 and is connected to the hollow structure between the external net 21 and the internal net 22;
[0044] When the filter 2 is blocked by dust, the amount of outside air entering is reduced, causing the temperature in the cabinet 1 to rise. As the temperature rises, the thermoelectric generator 12 generates electricity under the action of the temperature difference, and the electricity is transmitted to the electromagnet 32 through the circuit, so that the electromagnet 32 is energized. The electromagnet 32 generates magnetic force, and the magnetic force attracts the slider 33 to move along the sliding cavity 31. At this time, the slider 33 is attracted by the magnet, and the spring is gradually pulled by the attraction of the electromagnet 32. When the magnetic force generated by the electromagnet 32 is greater than the magnetic force of the magnet, the slider 33 detaches from the magnet and moves along the sliding cavity 31. The movable cavity 31 moves rapidly toward the electromagnet 32; during the movement of the slider 33, the filter screen 2 is driven to move. Under the pulling force of the slider 33, the filter screen 2 changes from a relaxed state to a tight state. The dust on the filter screen 2 is ejected outward at the moment of tension, and some dust is removed from the surface of the filter screen 2. When the outer screen 21 and the inner screen 22 are stretched from a relaxed state to a tight state under the action of the slider 33, the rubber column 23 supports the outer screen 21 and the inner screen 22, preventing the outer screen 21 from colliding with the inner screen 22, which may cause dust to enter the gap through the outer screen 21.
[0045] When the electromagnet 32 is energized, the controller controls the motor to start, and the driving shaft in the motor drives the bevel gear to rotate. The bevel gears mesh with each other, driving the rotating shaft 36 to rotate. During the rotation of the rotating shaft 36, the cam 35 is driven to rotate. The cam 35 rotates and hits the impact block 37. The impact block 37 is hit and moves to the side away from the cam 35 along the active chamber 34. During the movement of the impact block 37, it contacts the airbag 38. The impact block 37 squeezes the airbag 38, so that the pressure in the airbag 38 is greater than the external pressure. The gas in the airbag 38 is then discharged outward through the one-way valve in the air outlet pipe. The gas in the airbag 38 enters the gap between the outer net 21 and the inner net 22, and the gas then moves from the middle to both sides. The gas moves from the gap to the outer net 21, spraying out the dust blocked on the outer net 21 from the inside to the outside, cleaning the dust on the outer net 21, and increasing the amount of external air entering.
[0046] During the movement of the impact block 37, the impact block 37 drives the top column to move, and the top column hits the cabinet body 1. The cabinet body 1 is hit and causes the filter screen 2 to vibrate. During the shaking of the filter screen 2, dust attached to the surface of the filter screen 2 is shaken off, preventing the dust from clogging the air holes in the filter screen 2, resulting in a small amount of outside air entering. This increases the amount of outside air entering.
[0047] As the temperature inside the cabinet 1 gradually decreases, the power generated by the thermoelectric generator 12 decreases, causing the magnetic force generated by the electromagnet 32 to decrease. The slider 33 then moves under the elastic force of the spring, and the slider 33 moves toward the side close to the filter 2. During the movement of the slider 33, the filter 2 is driven to move, and the filter 2 changes from a taut state to a relaxed state.
[0048] As a specific embodiment of the present invention, the cooling device 4 includes: a cooling chamber 41, the cooling chamber 41 is symmetrically arranged on both sides of the motor, a filter plate 42 is provided on the side of the cooling chamber 41 close to the inside of the cabinet 1, and an air outlet 43 is provided on the side of the cooling chamber 41 away from the motor, and a second filter plate 431 is provided on the air outlet 43.
[0049] As a specific embodiment of the present invention, a cooling fan 44 is provided in the cooling chamber 41, and the cooling fan 44 is provided with a rotating shaft 45. A driving gear 361 is provided on the rotating shaft 36, and a driven gear 451 is provided on the rotating shaft 45. The driving gear 361 meshes with the driven gear 451.
[0050] In the process of the driving shaft in the motor driving the rotating shaft 36 to rotate, the rotating shaft 36 drives the driving gear 361 to rotate, the driving gear 361 engages the transmission driven gear 451, the driven gear 451 drives the rotating shaft 45 to rotate, the rotating shaft 45 drives the cooling fan 44 to rotate, and the cooling fan 44 rotates, so that the hot air in the cabinet 1 is filtered by the No. 1 filter plate 42 and then enters the cooling chamber 41. The hot air moves under the action of the cooling fan 44, and the hot air moves along the cooling chamber 41 to the side away from the cabinet 1. In the process of the hot air moving, it encounters the No. 2 filter plate 431, and the No. 2 filter plate 431 filters the hot air again, and finally discharged outward through the air outlet 43, thereby achieving the cooling of the temperature of the cabinet 1.
[0051] As a specific embodiment of the present invention, a temperature sensor 13 is provided on the top of the cabinet 1 , an alarm 14 is provided on the outer wall of the cabinet 1 , and the temperature sensor 13 is electrically connected to the alarm 14 through a controller.
[0052] When the temperature inside the cabinet 1 continues to rise, the temperature sensor 13 converts the temperature signal inside the cabinet 1 into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. If the temperature exceeds the predetermined temperature, the controller immediately controls the alarm 14 to start. The alarm 14 then generates an audible and visual alarm to remind the staff to cool down the cabinet 1 in time to avoid excessive temperature, which may cause the security cabinet to spontaneously combust, thereby ensuring the normal operation of the electrical components in the cabinet 1.
[0053] Working principle of the present invention:
[0054] When the filter 2 is blocked by dust, the amount of outside air entering is reduced, causing the temperature in the cabinet 1 to rise. As the temperature rises, the thermoelectric generator 12 generates electricity under the action of the temperature difference, and the electricity is transmitted to the electromagnet 32 through the circuit, so that the electromagnet 32 is energized. The electromagnet 32 generates magnetic force, and the magnetic force attracts the slider 33 to move along the sliding cavity 31. At this time, the slider 33 is attracted by the magnet, and the spring is gradually pulled by the attraction of the electromagnet 32. When the magnetic force generated by the electromagnet 32 is greater than the magnetic force of the magnet, the slider 33 detaches from the magnet and moves along the sliding cavity 31. The movable cavity 31 moves rapidly toward the electromagnet 32; during the movement of the slider 33, the filter screen 2 is driven to move. Under the pulling force of the slider 33, the filter screen 2 changes from a relaxed state to a tight state. The dust on the filter screen 2 is ejected outward at the moment of tension, and some dust is removed from the surface of the filter screen 2. When the outer screen 21 and the inner screen 22 are stretched from a relaxed state to a tight state under the action of the slider 33, the rubber column 23 supports the outer screen 21 and the inner screen 22, preventing the outer screen 21 from colliding with the inner screen 22, which may cause dust to enter the gap through the outer screen 21.
[0055] When the electromagnet 32 is energized, the controller controls the motor to start, and the driving shaft in the motor drives the bevel gear to rotate. The bevel gears mesh with each other, driving the rotating shaft 36 to rotate. During the rotation of the rotating shaft 36, the cam 35 is driven to rotate. The cam 35 rotates and hits the impact block 37. The impact block 37 is hit and moves to the side away from the cam 35 along the active chamber 34. During the movement of the impact block 37, it contacts the airbag 38. The impact block 37 squeezes the airbag 38, so that the pressure in the airbag 38 is greater than the external pressure. The gas in the airbag 38 is then discharged outward through the one-way valve in the air outlet pipe. The gas in the airbag 38 enters the gap between the outer net 21 and the inner net 22, and the gas then moves from the middle to both sides. The gas moves from the gap to the outer net 21, spraying out the dust blocked on the outer net 21 from the inside to the outside, cleaning the dust on the outer net 21, and increasing the amount of external air entering.
[0056] During the movement of the impact block 37, the impact block 37 drives the top column to move, and the top column hits the cabinet body 1. The cabinet body 1 is hit and causes the filter screen 2 to vibrate. During the shaking of the filter screen 2, dust attached to the surface of the filter screen 2 is shaken off, preventing the dust from clogging the air holes in the filter screen 2, resulting in a small amount of outside air entering. This increases the amount of outside air entering.
[0057] As the temperature inside the cabinet 1 gradually drops, the power generated by the thermoelectric generator 12 decreases, causing the magnetic force generated by the electromagnet 32 to decrease. The slider 33 then moves under the elastic force of the spring, and moves toward the side close to the filter 2. During the movement of the slider 33, the filter 2 is driven to move, and the filter 2 changes from a taut state to a relaxed state.
[0058] When the driving shaft in the motor drives the rotating shaft 36 to rotate, the rotating shaft 36 drives the driving gear 361 to rotate, the driving gear 361 meshes with the driven gear 451, and the driven gear 451 drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the cooling fan 44 to rotate. The cooling fan 44 rotates, so that the hot air in the cabinet 1 is filtered by the first filter plate 42 and then enters the cooling chamber 41. The hot air moves under the action of the cooling fan 44, and the hot air moves along the cooling chamber 41 to the side away from the cabinet 1. During the movement of the hot air, it encounters the second filter plate 431, and the second filter plate 431 filters the hot air again. Finally, it is discharged outward through the air outlet 43, thereby achieving the cooling of the temperature of the cabinet 1;
[0059] When the temperature inside the cabinet 1 continues to rise, the temperature sensor 13 converts the temperature signal inside the cabinet 1 into an electrical signal and transmits it to the controller. The controller analyzes the electrical signal. If the temperature exceeds the predetermined temperature, the controller immediately controls the alarm 14 to start. The alarm 14 then generates an audible and visual alarm to remind the staff to cool down the cabinet 1 in time to avoid excessive temperature, which may cause the security cabinet to spontaneously combust, thereby ensuring the normal operation of the electrical components in the cabinet 1.
