Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinets, and particularly to a distribution cabinet with a temperature alarm function. Background Art

[0002] With the initial formation and development of the power system, simple distribution devices began to appear, which were used to distribute the electric energy generated by power plants to different electrical equipment and areas. These early distribution cabinets had relatively simple structures and were mainly composed of some basic components such as switches and fuses. Their functions were also relatively single, mainly realizing the on-off control of electric energy and basic overload protection.

[0003] The patent with the publication number CN222547015U relates to a distribution cabinet with a temperature detection and alarm function, including a cabinet body. Four right-angle support rods are vertically installed inside the cabinet body. The two ends of the four right-angle support rods are respectively close to the inner corner edges of the cabinet body. The openings of the four right-angle support rods correspond to each other. A plurality of clamping holes are formed on one side of the right-angle support rods. The power control equipment is installed through the mutual cooperation between the right-angle support rods inside the cabinet body, and the detection component is also installed between the right-angle support rods. The temperature sensor main body on the square frame can detect the temperature inside the cabinet in real time. When the temperature inside the cabinet rises to a certain level, the alarm main body electrically connected to it will give an alarm, reminding the staff to detect the heat dissipation structure inside the cabinet or the power control equipment itself, preventing the reduction of the service life of the power control equipment inside the cabinet caused by working in a high-temperature environment for a long time. However, when the device detects high temperature, it requires the staff to manually cool it down, and it is very difficult to cool itself. If the staff does not hear the alarm, it is easy to cause damage to the electronic components inside the distribution cabinet. Therefore, a distribution cabinet with a temperature alarm function is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a distribution cabinet with a temperature alarm function for the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a power distribution cabinet with a temperature alarm function, including a housing, the inner wall of the housing is rotatably connected with a cabinet door, the left side of the housing is fixedly connected with an alarm lamp, the inner wall of the housing is fixedly connected with a ventilation window, a fan assembly is arranged on the inner wall of the ventilation window, a filter plate is fixedly connected to the inner wall of the ventilation window, a motor is fixedly connected to the inner wall of the housing, the output end of the motor is fixedly connected with a threaded rod, a brush plate is threadedly connected to the circumferential surface of the threaded rod, a guide rod is fixedly connected to the inner wall of the housing, a connecting block is fixedly connected to the right side of the brush plate, a reciprocating lead screw is rotatably connected to the inner wall of the connecting block, a transmission wheel is fixedly connected to the circumferential surface of the reciprocating lead screw, a pushing device for facilitating workers to inspect is arranged on the inner wall of the housing, a collecting device for collecting residual dust is arranged on the inner wall of the housing, a cleaning plate is movably connected to the circumferential surface of the transmission wheel, the alarm lamp is electrically connected to a temperature detector, the fan assembly is electrically connected to the temperature detector, the inner wall of the brush plate is slidably connected to the circumferential surface of the guide rod, the left side of the ventilation window is in contact with the circumferential surface of the transmission wheel, the right side of the filter plate is in contact with the left side of the cleaning plate. When the temperature of the power distribution cabinet is too high, the temperature detector will detect the temperature of the power distribution cabinet, conduct an electrical signal to the alarm lamp to make it alarm, thereby attracting maintenance personnel to detect and prevent the temperature in the power distribution cabinet from being too high caused by a short circuit and fire inside. It can also blow out the hot air inside the power distribution cabinet, so as to automatically cool the inside of the power distribution cabinet, and further avoid damage to the internal electronic components caused by the continuous increase of the temperature of the power distribution cabinet. At the same time, it can scrape off the dust generated on the surface of the filter plate, so as to improve the ventilation efficiency inside the power distribution cabinet. It can also make the cleaning plate move reciprocally, which can further improve the dust cleaning effect of the filter plate, so as to quickly reduce the temperature inside the power distribution cabinet.

[0006] Preferably, the pushing device includes a first sliding rod, which is slidably connected to the inner wall of the housing through a spring. A force-bearing plate is fixedly connected to the bottom of the first sliding rod, and a first inclined plate is fixedly connected to the top of the force-bearing plate. A sliding push plate is slidably connected to the inner wall of the housing, and a first fixing block is fixedly connected to the inner wall of the housing. A moving rod is slidably connected to the inner wall of the first fixing block. A second fixing block is fixedly connected to the inner wall of the housing, and an elastic rod is slidably connected to the inner wall of the second fixing block through a spring. A pushing block is fixedly connected to the front of the elastic rod. A baffle is fixedly connected to the bottom of the moving rod. The circumferential surface of the moving rod is in contact with the inner wall of the pushing block, and the inner wall of the housing is in contact with the left side of the pushing block. When the temperature of the power distribution cabinet is too high, the limit of the cabinet door can be released, so that the cabinet door can be easily opened, avoiding the situation that when there is a fire inside the power distribution cabinet in an emergency, the high temperature of the cabinet door makes it difficult for the fire extinguishing personnel to open the cabinet door, thus affecting the fire extinguishing progress of the power distribution cabinet and the rescue of the fire situation. At the same time, it can make the pushing block impact the cabinet door, thereby pushing open the cabinet door, further helping the fire extinguishing personnel to extinguish the fire inside the power distribution cabinet, avoiding the further spread of the fire, quickly limiting the cabinet door, and achieving the effect of automatically locking the cabinet door, so as to improve the working efficiency of the power distribution cabinet during use.

[0007] Preferably, the collecting device includes a collecting box, which is fixedly connected to the inner wall of the housing. A straight plate is fixedly connected to the left side of the sliding push plate. A movable door is rotatably connected to the inner wall of the collecting box through a torsion spring. A second inclined plate is fixedly connected to the front of the sliding push plate. A second sliding rod is slidably connected to the inner wall of the second inclined plate through a spring. A knocking block is fixedly connected to the left side of the second sliding rod. A convex block is fixedly connected to the right side of the filter plate. The right side of the straight plate is in contact with the left side of the movable door, and the right side of the filter plate is in contact with the knocking block. When cleaning the ventilation window, the scraped dust can be collected. After the dust falls into the interior of the collecting box, the straight plate moves upward and no longer presses the movable door, so that the movable door rotates through the torsion spring, thereby closing the dust falling into the interior of the collecting box, avoiding the dust being blown into the electronic components inside the power distribution cabinet, which is likely to cause the problem of electronic short circuit inside the power distribution cabinet. At the same time, it makes the surface of the filter plate vibrate, thereby vibrating out the dust remaining in the holes inside the filter plate, improving the ventilation effect of the filter plate and the service life of the filter plate.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. The power distribution cabinet with temperature alarm function operates through the cooperation among the shell, cabinet door, alarm lamp, ventilation window, fan assembly, temperature detector, filter plate, motor, threaded rod, brush plate, guide rod, connecting block, reciprocating lead screw and transmission wheel. When the temperature of the power distribution cabinet is too high, the temperature detector will detect the temperature of the power distribution cabinet, conduct the electrical signal to the alarm lamp to make it give an alarm, so as to attract maintenance personnel for detection and prevent the temperature inside the power distribution cabinet from being too high caused by short - circuit fire. It can also blow out the hot air inside the power distribution cabinet to automatically cool the inside of the power distribution cabinet, thus avoiding the continuous increase of the temperature of the power distribution cabinet from damaging the internal electronic components. At the same time, it can scrape off the dust generated on the surface of the filter plate, improve the ventilation efficiency inside the power distribution cabinet, and make the cleaning plate move reciprocally, which can further improve the dust cleaning effect of the filter plate and quickly reduce the temperature inside the power distribution cabinet.

[0009] 2. The power distribution cabinet with temperature alarm function operates through the cooperation among the first sliding rod, stress plate, first inclined plate, sliding push plate, first fixed block, moving rod, second fixed block, elastic rod, push block and baffle. When the temperature of the power distribution cabinet is too high, it can release the limit of the cabinet door so that the cabinet door can be easily opened, avoiding that in case of an emergency of fire inside the power distribution cabinet, the high temperature of the cabinet door makes it difficult for the fire - fighting personnel to open the cabinet door, thus affecting the fire - fighting progress of the power distribution cabinet and the rescue of the fire situation. At the same time, it can make the push block impact the cabinet door to push it open, further helping the fire - fighting personnel to extinguish the fire inside the power distribution cabinet, preventing the fire from spreading further, quickly limiting the cabinet door and achieving the effect of automatically locking the cabinet door, so as to improve the working efficiency of the power distribution cabinet during use.

[0010] 3. The power distribution cabinet with temperature alarm function operates through the cooperation among the collection box, straight plate, movable door, second inclined plate, second sliding rod, knocking block, convex block and cleaning plate. When cleaning the ventilation window, it can collect the scraped dust. After the dust falls into the interior of the collection box, the straight plate moves upward and no longer presses the movable door, so that the movable door rotates through the torsion spring, and then can seal the dust falling into the interior of the collection box, avoiding the dust being blown into the electronic components inside the power distribution cabinet, which is likely to cause the problem of electronic short - circuit inside the power distribution cabinet. At the same time, it makes the surface of the filter plate vibrate, and then can shake out the dust remaining in the holes of the filter plate, improving the ventilation effect of the filter plate and the service life of the filter plate.

[0013] 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 of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1 - 7, an embodiment of the present invention is: a power distribution cabinet with a temperature alarm function, including a housing 1, the inner wall of the housing 1 is rotatably connected with a cabinet door 2, the left side of the housing 1 is fixedly connected with an alarm lamp 3, the inner wall of the housing 1 is fixedly connected with a ventilation window 4, the inner wall of the ventilation window 4 is provided with a fan assembly 5. When the temperature of the power distribution cabinet is too high, the temperature detector 6 will detect the temperature of the power distribution cabinet, conduct the electrical signal to the alarm lamp 3 to make it alarm, thereby attracting maintenance personnel to detect and prevent the temperature of the power distribution cabinet from being too high due to short circuit and fire inside. When the electrical signal is conducted to the alarm lamp 3, it will be conducted to the fan assembly 5 and start at the same time, so that the hot air inside the power distribution cabinet can be blown out, enabling automatic cooling of the inside of the power distribution cabinet, and further preventing the temperature of the power distribution cabinet from continuously rising and damaging the internal electronic components. The inner wall of the ventilation window 4 is fixedly connected with a filter plate 7, the inner wall of the housing 1 is fixedly connected with a motor 8, the output end of the motor 8 is fixedly connected with a threaded rod 9, the circumferential surface of the threaded rod 9 is threadedly connected with a brush plate 10, the inner wall of the housing 1 is fixedly connected with a guide rod 11, the right side of the brush plate 10 is fixedly connected with a connecting block 12, the inner wall of the connecting block 12 is rotatably connected with a reciprocating screw rod 13, the circumferential surface of the reciprocating screw rod 13 is fixedly connected with a transmission wheel 14, the inner wall of the housing 1 is provided with a pushing device 15 for facilitating workers to check, the inner wall of the housing 1 is provided with a collecting device 16 for collecting residual dust, the circumferential surface of the transmission wheel 14 is movably connected with a cleaning plate 17, the alarm lamp 3 is electrically connected with the temperature detector 6, the fan assembly 5 is electrically connected with the temperature detector 6, the inner wall of the brush plate 10 slides on the circumferential surface of the guide rod 11, the left side of the ventilation window 4 is in contact with the circumferential surface of the transmission wheel 14, the right side of the filter plate 7 is in contact with the left side of the cleaning plate 17. At the same time, when the filter plate 7 inside the power distribution cabinet is blocked, the motor 8 starts to drive the threaded rod 9 to rotate. During the rotation of the threaded rod 9, the thread groove on the surface of the threaded rod 9 will contact the slider arranged inside the brush plate 10, and then the brush plate 10 can move along the rotation direction of the threaded rod 9 through friction, so that the dust generated on the surface of the filter plate 7 can be scraped off, improving the ventilation efficiency inside the power distribution cabinet. The movement of the brush plate 10 drives the connecting block 12 to move, the movement of the connecting block 12 drives the reciprocating screw rod 13 to move, the movement of the reciprocating screw rod 13 drives the transmission wheel 14 to move. During the movement of the transmission wheel 14, it will contact the ventilation window 4 and generate friction to make the transmission wheel 14 rotate. The rotation of the transmission wheel 14 drives the reciprocating screw rod 13 to rotate. The rotation of the reciprocating screw rod 13 will contact the thread arranged on the surface of the reciprocating screw rod 13 through the slider arranged inside the cleaning plate 17, so that the cleaning plate 17 can move reciprocally, further improving the dust cleaning effect of the filter plate 7 and enabling the temperature inside the power distribution cabinet to be quickly reduced.

[0015] The driving device 15 includes a first sliding rod 151. The first sliding rod 151 is slidably connected to the inner wall of the housing 1 through a spring. A force-bearing plate 152 is fixedly connected to the bottom of the first sliding rod 151. A first inclined plate 153 is fixedly connected to the top of the force-bearing plate 152. A sliding push plate 154 is slidably connected to the inner wall of the housing 1. When the temperature of the power distribution cabinet is too high, the motor 8 will extend the time of the clockwise rotation of the threaded rod 9, so that the connecting block 12 can move to a position that it could not originally reach when moving downward. At this time, the connecting block 12 drives the sliding push plate 154 to continue moving downward, so that the sliding push plate 154 contacts the force-bearing plate 152 and pushes the force-bearing plate 152 downward. The force-bearing plate 152 moves downward to drive the first sliding rod 151 to move downward, and the first sliding rod 151 moves downward to drive the first inclined plate 153 to move downward, so as to release the limit of the cabinet door 2, making the cabinet door 2 easy to open. This can prevent the temperature of the cabinet door 2 from being too high when there is an emergency of fire inside the power distribution cabinet, making it difficult for the fire extinguishing personnel to open the cabinet door 2, which will affect the fire extinguishing progress of the power distribution cabinet and the rescue of the fire situation. A first fixing block 155 is fixedly connected to the inner wall of the housing 1. A moving rod 156 is slidably connected to the inner wall of the first fixing block 155. A second fixing block 157 is fixedly connected to the inner wall of the housing 1. An elastic rod 158 is slidably connected to the inner wall of the second fixing block 157 through a spring. A pushing block 159 is fixedly connected to the front of the elastic rod 158. A baffle 1510 is fixedly connected to the bottom of the moving rod 156. The circumferential surface of the moving rod 156 contacts the inner wall of the pushing block 159. The inner wall of the housing 1 contacts the left side of the pushing block 159. At the same time, when the sliding push plate 154 moves downward, it will contact the baffle 1510 and push the baffle 1510 downward. The baffle 1510 moves downward to drive the moving rod 156 to move downward. When the moving rod 156 moves downward, it will make the moving rod 156 leave the inside of the pushing block 159, thus releasing the limit of the elastic rod 158, so that the elastic rod 158 moves forward through the spring and drives the pushing block 159 to move together, so that the pushing block 159 can impact the cabinet door 2, thereby pushing open the cabinet door 2, which can further help the fire extinguishing personnel to extinguish the fire inside the power distribution cabinet and prevent the fire from spreading further. When the cabinet door 2 is normally closed, the cabinet door 2 will exert a squeezing force on the first inclined plate 153, causing the first sliding rod 151 to move downward. The downward movement of the first sliding rod 151 will drive the force-bearing plate 152 to move downward, so as to quickly limit the cabinet door 2 and achieve the effect of automatically locking the cabinet door 2, improving the working efficiency of the power distribution cabinet during use.

[0016] Working principle: When the temperature of the power distribution cabinet is too high, the temperature detector 6 will detect the temperature of the power distribution cabinet, conduct the electrical signal to the alarm light 3 to make it alarm, thus attracting maintenance personnel for detection and preventing the temperature rise inside the power distribution cabinet caused by short-circuit fire. When the electrical signal is conducted to the alarm light 3, it will be conducted to the fan assembly 5 at the same time and start, so that the hot air inside the power distribution cabinet can be blown out, enabling automatic cooling inside the power distribution cabinet, and further preventing the continuous rise of the temperature of the power distribution cabinet from damaging the internal electronic components. At the same time, when the filter plate 7 inside the power distribution cabinet is blocked, the motor 8 starts to drive the threaded rod 9 to rotate. During the rotation of the threaded rod 9, the thread groove on the surface of the threaded rod 9 will contact the slider arranged inside the brush plate 10, and then through the frictional force, the brush plate 10 can move along the rotation direction of the threaded rod 9, so that the dust generated on the surface of the filter plate 7 can be scraped off, enabling the ventilation efficiency inside the power distribution cabinet to be improved. The movement of the brush plate 10 drives the connecting block 12 to move, the movement of the connecting block 12 drives the reciprocating screw rod 13 to move, the movement of the reciprocating screw rod 13 drives the transmission wheel 14 to move. During the movement of the transmission wheel 14, it will contact the ventilation window 4 and generate frictional force to make the transmission wheel 14 rotate. The rotation of the transmission wheel 14 drives the reciprocating screw rod 13 to rotate. The rotation of the reciprocating screw rod 13 will contact the thread arranged on the surface of the reciprocating screw rod 13 through the slider arranged inside the cleaning plate 17, so that the cleaning plate 17 can move reciprocally, thus further improving the dust cleaning effect of the filter plate 7 and enabling the temperature inside the power distribution cabinet to be quickly reduced.

[0017] When the temperature of the power distribution cabinet is too high, the motor 8 will extend the clockwise rotation time of the threaded rod 9, so that the connecting block 12 can move to a position that could not be reached originally when moving downward. At this time, the connecting block 12 drives the sliding push plate 154 to continue moving downward, so that the sliding push plate 154 contacts the stress plate 152 and pushes the stress plate 152 downward. The downward movement of the stress plate 152 drives the first sliding rod 151 to move downward, and the downward movement of the first sliding rod 151 drives the first inclined plate 153 to move downward, so that the limit of the cabinet door 2 can be released, and the cabinet door 2 can be easily opened. To avoid that in case of an emergency of fire inside the power distribution cabinet, the high temperature of the cabinet door 2 makes it difficult for the fire extinguishing personnel to open the cabinet door 2, which in turn affects the fire extinguishing progress of the power distribution cabinet and the rescue of the fire situation. At the same time, when the sliding push plate 154 moves downward, it will contact the baffle 1510 and push the baffle 1510 downward. The downward movement of the baffle 1510 drives the moving rod 156 to move downward. When the moving rod 156 moves downward, the moving rod 156 will leave the inside of the push block 159, thus releasing the limit of the elastic rod 158, so that the elastic rod 158 moves forward through the spring and drives the push block 159 to move together, so that the push block 159 can impact the cabinet door 2, and then push open the cabinet door 2, so as to further help the fire extinguishing personnel to extinguish the fire inside the power distribution cabinet and avoid the further spread of the fire. When the cabinet door 2 is normally closed, the cabinet door 2 will exert a squeezing force on the first inclined plate 153, causing the first sliding rod 151 to move downward. The downward movement of the first sliding rod 151 will drive the stress plate 152 to move downward, so that the cabinet door 2 can be quickly limited and automatically locked, improving the working efficiency of the power distribution cabinet during use.

[0018] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, the collection device 16 includes a collection box 161, the collection box 161 is fixedly connected to the inner wall of the housing 1, a straight plate 162 is fixedly connected to the left side of the sliding push plate 154, and a movable door 163 is rotatably connected to the inner wall of the collection box 161 through a torsion spring. When cleaning the ventilation window 4, the downward movement of the sliding push plate 154 will drive the straight plate 162 to move downward, and the downward movement of the straight plate 162 will contact the movable door 163 and push the movable door 163 to turn downward, so that the collection box 161 can be opened, so that the scraped dust can be collected. After the dust falls into the interior of the collection box 161, the straight plate 162 moves upward and no longer presses the movable door 163, so that the movable door 163 rotates through the torsion spring, and then the dust falling into the interior of the collection box 161 can be sealed, preventing the dust from being blown into the electronic components inside the power distribution cabinet, which may easily lead to the problem of electronic short - circuit inside the power distribution cabinet. A second inclined plate 164 is fixedly connected to the front part of the sliding push plate 154, a second sliding rod 165 is slidably connected to the inner wall of the second inclined plate 164 through a spring, a knocking block 166 is fixedly connected to the left side of the second sliding rod 165, a convex block 167 is fixedly connected to the right side of the filter plate 7, the right side of the straight plate 162 is in contact with the left side of the movable door 163, and the right side of the filter plate 7 is in contact with the knocking block 166. At the same time, the movement of the sliding push plate 154 drives the second inclined plate 164 to move, the movement of the second inclined plate 164 drives the second sliding rod 165 to move, the movement of the second sliding rod 165 drives the knocking block 166 to move, and the knocking block 166 contacts the convex block 167 during the movement process, so that the knocking block 166 is subjected to the extrusion force of the convex block 167, causing the knocking block 166 to move to the right and stretch the spring. After the knocking block 166 passes over the convex block 167, it no longer receives the extrusion force of the convex block 167, so that the knocking block 166 is reset by the elastic force of the spring, which can make the knocking block 166 knock on the surface of the filter plate 7, so that the surface of the filter plate 7 vibrates, and then the dust remaining in the holes inside the filter plate 7 can be shaken out, improving the ventilation effect of the filter plate 7 and the service life of the filter plate 7.

[0019] Working principle: When cleaning the ventilation window 4, the downward movement of the sliding push plate 154 drives the straight plate 162 to move downward. The downward movement of the straight plate 162 contacts the movable door 163 and pushes the movable door 163 to turn downward, enabling the collection box 161 to be opened, so that the scraped dust can be collected. After the dust falls into the interior of the collection box 161, the straight plate 162 moves upward and no longer presses the movable door 163, causing the movable door 163 to rotate through the torsion spring, thereby sealing the dust falling into the interior of the collection box 161 and preventing the dust from being blown onto the electronic components inside the power distribution cabinet, which may easily lead to the problem of electronic short - circuit inside the power distribution cabinet. At the same time, the movement of the sliding push plate 154 drives the movement of the second inclined plate 164, the movement of the second inclined plate 164 drives the movement of the second sliding rod 165, and the movement of the second sliding rod 165 drives the movement of the knocking block 166. During the movement of the knocking block 166, it contacts the convex block 167, so that the knocking block 166 is subjected to the extrusion force of the convex block 167, causing the knocking block 166 to move to the right and stretch the spring. After the knocking block 166 passes over the convex block 167, it is no longer subjected to the extrusion force of the convex block 167, and the knocking block 166 is reset by the elastic force of the spring, enabling the knocking block 166 to knock on the surface of the filter plate 7, thereby causing vibration on the surface of the filter plate 7, and then being able to shake out the dust remaining in the holes inside the filter plate 7, improving the ventilation effect of the filter plate 7 and the service life of the filter plate 7.
