Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, specifically to a power distribution cabinet with a temperature alarm function. Background Technology

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

[0003] Patent CN222547015U discloses a power distribution cabinet with a temperature detection and alarm function. The cabinet includes a cabinet body with four right-angled supports vertically mounted inside. The ends of the four supports are located near the internal corner edges of the cabinet, and their openings correspond to each other. Multiple mounting holes are provided on one side of each support. Control equipment is installed through the cooperation of the right-angled supports inside the cabinet. A detection component is also installed between the right-angled supports. A temperature sensor on a square frame can detect the temperature inside the cabinet in real time. When the temperature inside the cabinet rises to a certain level, an alarm connected to the device will sound, reminding staff to check the heat dissipation structure or the control equipment itself to prevent reduced lifespan due to prolonged operation at high temperatures. However, when the device detects high temperatures, staff need to manually cool it down, which is difficult to do. If staff do not hear the alarm, it can easily damage the electronic components inside the power distribution cabinet. Therefore, a power 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 power distribution cabinet with a temperature alarm function, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a power distribution cabinet with a temperature alarm function, comprising a housing, a cabinet door rotatably connected to the inner wall of the housing, an alarm light fixedly connected to the left side of the housing, a ventilation window fixedly connected to the inner wall of the housing, a fan assembly disposed on the inner wall of the ventilation window, a filter plate fixedly connected to the inner wall of the ventilation window, a motor fixedly connected to the inner wall of the housing, a threaded rod fixedly connected to the output end of the motor, a brush plate threadedly connected to the circumferential surface of the threaded rod, a guide rod fixedly connected to the inner wall of the housing, a connecting block fixedly connected to the right side of the brush plate, a reciprocating screw rotatably connected to the inner wall of the connecting block, a transmission wheel fixedly connected to the circumferential surface of the reciprocating screw, a pushing device for convenient worker inspection disposed on the inner wall of the housing, a collecting device for collecting residual dust disposed on the inner wall of the housing, a cleaning plate movably connected to the circumferential surface of the transmission wheel, and the alarm light 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, and the right side of the filter plate is in contact with the left side of the cleaning plate. When the temperature of the distribution cabinet is too high, the temperature detector will detect the temperature of the distribution cabinet and transmit the electrical signal to the alarm light to trigger an alarm, thereby attracting maintenance personnel to conduct inspections and take preventive measures to avoid overheating caused by short circuits and fires inside the distribution cabinet. It can also blow out the hot air inside the distribution cabinet, enabling automatic cooling of the distribution cabinet and preventing the temperature from rising continuously and damaging the internal electronic components. At the same time, it can remove dust from the surface of the filter plate, improving the ventilation efficiency inside the distribution cabinet. It can also allow the cleaning plate to move back and forth, further improving the dust removal effect of the filter plate and quickly reducing the temperature inside the distribution cabinet.

[0006] Preferably, the pushing device includes a sliding rod, which is slidably connected to the inner wall of the outer casing via a spring. A force-bearing plate is fixedly connected to the bottom of the sliding rod, and an 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 outer casing. A fixing block is fixedly connected to the inner wall of the outer casing, and a moving rod is slidably connected to the inner wall of the fixing block. A second fixing block is fixedly connected to the inner wall of the outer casing, and a spring rod is slidably connected to the inner wall of the fixing block via a spring. A push block is fixedly connected to the front of the spring rod, and a baffle is fixedly connected to the bottom of the moving rod. The circumferential surface of the moving rod contacts the inner wall of the push block. The inner wall contacts the left side of the push block. When the temperature of the distribution cabinet is too high, it can engage the limit switch of the cabinet door, allowing the door to be easily opened. This prevents the cabinet door from becoming too hot to open in case of an emergency fire inside the distribution cabinet, thus affecting the progress of firefighting and the rescue of the fire. At the same time, the push block can impact the cabinet door, pushing it open to further assist firefighters in extinguishing the fire inside the distribution cabinet and preventing the fire from spreading further. It can quickly limit the cabinet door and automatically lock the cabinet door, thereby improving the working efficiency of the distribution cabinet during use.

[0007] Preferably, the collecting device includes a collecting box, which is fixedly connected to the inner wall of the outer shell. 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 via 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 via a spring. A striking block is fixedly connected to the left side of the second sliding rod. A protrusion is fixedly connected to the right side of the filter plate. The right side of the straight plate contacts the left side of the movable door, and the right side of the filter plate contacts the striking block. When the air vent is cleaned, the blown dust can be collected. After the dust falls into the collection box, the straight plate moves up and no longer squeezes the movable door, allowing the movable door to rotate via a torsion spring. This seals the dust inside the collection box, preventing it from being blown into the electronic components inside the distribution cabinet and potentially causing short circuits. At the same time, the surface of the filter plate vibrates, dislodging dust remaining in the pores of the filter plate, improving ventilation and extending its lifespan.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This power distribution cabinet with temperature alarm function works in concert with its casing, cabinet door, alarm light, ventilation window, fan assembly, temperature detector, filter plate, motor, threaded rod, brush plate, guide rod, connecting block, reciprocating screw, and transmission wheel. When the temperature of the power distribution cabinet is too high, the temperature detector will detect the temperature and transmit an electrical signal to the alarm light to trigger an alarm, thereby attracting maintenance personnel to inspect and prevent overheating caused by short circuits or fires inside the power distribution cabinet. It can also blow out hot air from inside the power distribution cabinet, enabling automatic cooling of the internal components and preventing damage to internal electronic components caused by continuous temperature rise. At the same time, it can remove dust from the surface of the filter plate, improving the ventilation efficiency inside the power distribution cabinet. The reciprocating movement of the cleaning plate can further improve the dust removal effect of the filter plate, enabling rapid reduction of the internal temperature of the power distribution cabinet.

[0009] 2. This distribution cabinet with temperature alarm function, through the coordinated operation of sliding rod 1, force plate, inclined plate 1, sliding push plate, fixed block 1, moving rod, fixed block 2, elastic rod, push block, and baffle, can easily open the cabinet door when the temperature is too high. This prevents the cabinet door from being too hot to open in case of an emergency fire, thus hindering the firefighting progress and the rescue efforts. Simultaneously, the push block can impact the cabinet door, pushing it open to further assist firefighters in extinguishing the fire inside the cabinet and preventing it from spreading. The cabinet cabinet can quickly limit the door's movement and automatically lock it, improving its operational efficiency during use.

[0010] 3. This distribution cabinet with temperature alarm function, through the coordinated operation of the collection box, straight plate, movable door, inclined plate two, sliding rod two, knocking block, protrusion, and cleaning plate, can collect the dust that falls when cleaning the ventilation window. After the dust falls into the collection box, the straight plate moves up and no longer squeezes the movable door, allowing the movable door to rotate through the torsion spring. This seals the dust inside the collection box, preventing dust from being blown into the electronic components inside the distribution cabinet and potentially causing short circuits. At the same time, the surface of the filter plate vibrates, which can shake out the dust remaining in the holes inside the filter plate, improving the ventilation effect and service life of the filter plate.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figures 1-7One embodiment of the present invention is as follows: a power distribution cabinet with a temperature alarm function includes a housing 1, a cabinet door 2 rotatably connected to the inner wall of the housing 1, an alarm light 3 fixedly connected to the left side of the housing 1, a ventilation window 4 fixedly connected to the inner wall of the housing 1, and a fan assembly 5 disposed on the inner wall of the ventilation window 4. When the temperature of the power distribution cabinet is too high, a temperature detector 6 will detect the temperature of the power distribution cabinet and transmit an electrical signal to the alarm light 3 to trigger an alarm, thereby attracting maintenance personnel to conduct inspections and take preventive measures to avoid overheating caused by short circuits and fires inside the power distribution cabinet. When the electrical signal is transmitted to the alarm light 3, it will also be transmitted to the fan assembly 5 and activated, thereby blowing out the hot air inside the power distribution cabinet, allowing the cabinet to cool down. The system automatically cools the inside of the power distribution cabinet, preventing damage to internal electronic components due to continuous temperature rise. A filter plate 7 is fixedly connected to the inner wall of the ventilation window 4. A motor 8 is fixedly connected to the inner wall of the outer casing 1. A threaded rod 9 is fixedly connected to the output end of the motor 8. A brush plate 10 is threadedly connected to the circumferential surface of the threaded rod 9. A guide rod 11 is fixedly connected to the inner wall of the outer casing 1. A connecting block 12 is fixedly connected to the right side of the brush plate 10. A reciprocating screw 13 is rotatably connected to the inner wall of the connecting block 12. A transmission wheel 14 is fixedly connected to the circumferential surface of the reciprocating screw 13. A pushing device 15 is provided on the inner wall of the outer casing 1 for convenient worker inspection. A collection device 16 is provided on the inner wall of the outer casing 1 for collecting residual dust. A cleaning plate 17 is movably connected to the circumferential surface of the drive wheel 14. The alarm light 3 is electrically connected to the temperature detector 6, and the fan assembly 5 is electrically connected to the temperature detector 6. The inner wall of the brush plate 10 is slidably connected to 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 drive wheel 14, and the right side of the filter plate 7 is in contact with the left side of the cleaning plate 17. Simultaneously, when the filter plate 7 inside the distribution cabinet becomes clogged, the motor 8 starts, driving the threaded rod 9 to rotate. During the rotation of the threaded rod 9, the threaded groove on the surface of the threaded rod 9 contacts the slider inside the brush plate 10. Through friction, the brush plate 10 moves in the direction of rotation of the threaded rod 9, thereby cleaning the surface of the filter plate 7. The dust generated on the surface is hung down, which improves the ventilation efficiency inside the 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 13 to move, and the movement of the reciprocating screw 13 drives the transmission wheel 14 to move. During the movement of the transmission wheel 14, it will come into contact with the ventilation window 4 and generate friction, causing the transmission wheel 14 to rotate. The rotation of the transmission wheel 14 drives the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 will cause the slider set inside the cleaning plate 17 to come into contact with the thread set on the surface of the reciprocating screw 13, so that the cleaning plate 17 can move back and forth, thereby further improving the dust cleaning effect of the filter plate 7 and enabling a rapid reduction in the temperature inside the distribution cabinet.

[0015] The pushing device 15 includes a sliding rod 151, which is slidably connected to the inner wall of the outer casing 1 by a spring. A force-bearing plate 152 is fixedly connected to the bottom of the sliding rod 151, and an 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 outer casing 1. When the temperature of the 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 it could not originally reach when it moves downward. At this time, the connecting block 12 drives the sliding push plate 154 to continue to move downward, so that the sliding push plate 154 contacts the force-bearing plate 152 and pushes the force-bearing plate 152 downward. The movable force plate 152 moves downward, causing the sliding rod 151 to move downward. The sliding rod 151 moves downward, causing the inclined plate 153 to move downward, thus contacting the limit of the cabinet door 2, allowing the cabinet door 2 to be easily opened. This prevents the cabinet door 2 from becoming too hot to open in an emergency situation where a fire occurs inside the distribution cabinet, thus affecting the progress of firefighting and the rescue of the fire. The inner wall of the outer shell 1 is fixedly connected to the fixing block 155, and the inner wall of the fixing block 155 is slidably connected to the moving rod 156. The inner wall of the outer shell 1 is fixedly connected to the fixing block 157. A spring rod 158 is slidably connected to the inner wall of 57 via a spring. A push block 159 is fixedly connected to the front of the spring 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 push block 159. The inner wall of the outer shell 1 contacts the left side of the push block 159. At the same time, the sliding push plate 154 moves downward and contacts the baffle 1510, pushing the baffle 1510 downward. The downward movement of the baffle 1510 causes the moving rod 156 to move downward. The downward movement of the moving rod 156 causes the moving rod 156 to leave the interior of the push block 159, thereby releasing the limiting position of the spring rod 158, allowing the spring rod 156 to move downward. The lever 158 moves forward via a spring, which in turn moves the push block 159. This allows the push block 159 to impact the cabinet door 2, pushing it open. This helps firefighters extinguish the fire inside the distribution cabinet and prevents the fire from spreading further. When the cabinet door 2 is closed normally, it exerts pressure on the inclined plate 153, causing the sliding rod 151 to move downward. The downward movement of the sliding rod 151 causes the force plate 152 to move downward, thus quickly limiting the cabinet door 2 and automatically locking it. This improves the efficiency of the distribution cabinet during use.

[0016] Working Principle: When the temperature of the distribution cabinet is too high, the temperature detector 6 will detect the temperature of the distribution cabinet and transmit the electrical signal to the alarm light 3 to trigger an alarm, thereby attracting maintenance personnel to inspect and take preventive measures to avoid overheating caused by short circuits or fires inside the distribution cabinet. When the electrical signal is transmitted to the alarm light 3, it will also be transmitted to the fan assembly 5 and start, thereby blowing out the hot air inside the distribution cabinet, which can automatically cool the inside of the distribution cabinet and prevent the temperature from rising continuously and damaging the internal electronic components. At the same time, when the filter plate 7 inside the distribution cabinet becomes clogged, the motor 8 starts and drives the threaded rod 9 to rotate. During the rotation of the threaded rod 9, the threaded groove on the surface of the threaded rod 9 will contact the slider set inside the brush plate 10, and then, through friction, make the filter plate 10 more resistant to heat. The brush plate 10 can move in the direction of rotation of the threaded rod 9, thereby removing dust from the surface of the filter plate 7 and improving the ventilation efficiency inside the distribution cabinet. The movement of the brush plate 10 drives the connecting block 12 to move, which in turn drives the reciprocating screw 13 to move. The reciprocating screw 13 then drives the transmission wheel 14 to move. During its movement, the transmission wheel 14 comes into contact with the ventilation window 4, generating friction that causes it to rotate. The rotation of the transmission wheel 14 drives the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 causes the slider inside the cleaning plate 17 to come into contact with the threads on its surface, allowing the cleaning plate 17 to move back and forth. This further improves the dust removal effect of the filter plate 7 and quickly reduces the temperature inside the distribution cabinet.

[0017] When the temperature of the distribution cabinet is too high, the motor 8 will extend the clockwise rotation time of the threaded rod 9, allowing the connecting block 12 to move to a position it could not reach before when moving downwards. At this time, the connecting block 12 drives the sliding push plate 154 to continue moving downwards, so that the sliding push plate 154 contacts the force plate 152 and pushes the force plate 152 downwards. The downward movement of the force plate 152 drives the sliding rod 151 to move downwards, and the downward movement of the sliding rod 151 drives the inclined plate 153 to move downwards, thereby contacting the limit of the cabinet door 2 and making the cabinet door 2 easy to open. This avoids the situation where the temperature of the cabinet door 2 is too high in an emergency when a fire occurs inside the distribution cabinet, making it difficult for firefighters to open the cabinet door 2, thus affecting the progress of fire fighting and the rescue of the fire. At the same time, the downward movement of the sliding push plate 154 will contact the baffle 1510 and push the baffle 1510. When baffle 1510 moves downward, it causes moving rod 156 to move downward. Moving rod 156 downward causes it to leave the inside of push block 159, thereby releasing the limit of spring rod 158. Spring rod 158 then moves forward through spring and drives push block 159 to move together. This allows push block 159 to hit cabinet door 2 and push cabinet door 2 open, which can further help firefighters extinguish the fire inside the distribution cabinet and prevent the fire from spreading further. When cabinet door 2 is closed normally, cabinet door 2 will exert pressure on inclined plate 153, causing sliding rod 151 to move downward. Sliding rod 151 moving downward will drive force plate 152 to move downward, thereby quickly limiting cabinet door 2 and automatically locking cabinet door 2, which can improve the working efficiency of distribution cabinet during use.

[0018] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the collecting device 16 includes a collecting box 161, which is fixedly connected to the inner wall of the outer casing 1. A straight plate 162 is fixedly connected to the left side of the sliding push plate 154. The inner wall of the collecting box 161 is rotatably connected to a movable door 163 via a torsion spring. When cleaning the ventilation window 4, the sliding push plate 154 moves downward, which drives the straight plate 162 to move downward. The downward movement of the straight plate 162 will contact the movable door 163 and push the movable door 163 to flip downward, so that it can... The collection box 161 is opened to collect the fallen dust. After the dust falls into the collection box 161, the straight plate 162 moves upward and no longer presses against the movable door 163, causing the movable door 163 to rotate via a torsion spring. This seals the dust inside the collection box 161, preventing it from being blown into the electronic components inside the distribution cabinet and potentially causing a short circuit. A second inclined plate 164 is fixedly connected to the front of the sliding push plate 154, and the inner wall of the second inclined plate 164 is open to... A sliding rod 165 is connected via a spring. A striking block 166 is fixedly connected to the left side of the sliding rod 165. A protrusion 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 striking block 166. Simultaneously, the sliding push plate 154 moves, causing the inclined plate 164 to move. The movement of the inclined plate 164 causes the sliding rod 165 to move, which in turn causes the striking block 166 to move. During the movement of the striking block 166, it will interact with the protrusion 167. The contact causes the striking block 166 to be pressed by the protrusion 167, causing the striking block 166 to move to the right and stretch the spring. After the striking block 166 passes the protrusion 167, it is no longer pressed by the protrusion 167, and the striking block 166 is reset by the elastic force of the spring. This allows the striking block 166 to strike the surface of the filter plate 7, thereby causing the surface of the filter plate 7 to vibrate. This can shake out the dust remaining in the holes inside the filter plate 7, improving the ventilation effect of the filter plate 7 and extending its service life.

[0019] Working principle: When cleaning ventilation window 4, the sliding push plate 154 moves downward, causing 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 flip downward, allowing the collection box 161 to open and collect the dust. After the dust falls into the collection box 161, the straight plate 162 moves upward and no longer presses against the movable door 163, causing the movable door 163 to rotate via the torsion spring. This seals the dust inside the collection box 161, preventing dust from being blown into the electronic components inside the distribution cabinet, which could easily cause a short circuit. At the same time, the movement of the sliding push plate 154 causes the inclined plate 2 to move downward. The movement of the inclined plate 164 causes the sliding rod 165 to move, which in turn causes the striking block 166 to move. During its movement, the striking block 166 comes into contact with the protrusion 167, which in turn causes the striking block 166 to be subjected to the squeezing force of the protrusion 167. This causes the striking block 166 to move to the right and stretch the spring. After the striking block 166 passes the protrusion 167, it is no longer subjected to the squeezing force of the protrusion 167, and the striking block 166 is reset by the elastic force of the spring. This allows the striking block 166 to strike the surface of the filter plate 7, thereby causing the surface of the filter plate 7 to vibrate. This, in turn, shakes out the dust remaining in the holes inside the filter plate 7, improving the ventilation effect and service life of the filter plate 7.
