Description

Technical Field

[0001] The invention relates to a power distribution cabinet, in particular to a multifunctional power distribution cabinet. Background Art

[0002] The power distribution cabinet is a terminal power distribution facility in the power supply and distribution process. Since there are many electrical appliances inside, a lot of heat is generated. If this heat accumulates for a long time, it will cause the electrical appliances to work inefficiently or even malfunction. Therefore, it needs to be equipped with certain heat dissipation devices. During the use of these electrical appliances, they are affected by various unfavorable factors and the probability of fire is high. Therefore, it is necessary to equip them with corresponding fire extinguishing devices. However, the existing power distribution cabinets have uneven heat conduction, low heat dissipation efficiency, and a relatively single fire extinguishing function, which makes the fire extinguishing effect poor. In addition, some power distribution cabinets that trigger the fire extinguishing action by sensing and identifying smoke and flames are difficult to stop the fire in time before it occurs, which is inconvenient to reduce economic losses and highlights the shortcomings of the existing technology.

When the crankshaft rotates, it can drive the sliding frame to slide back and forth. When the sliding frame slides back and forth, it can drive the push plate to move back and forth along the liquid storage tank through the upper polishing rod.

[0013] On the basis of the above technical solution, the temperature sensor is located at an upper position in the cabinet, and the controller is located at a bottom position in the cabinet.

[0014] Compared with the prior art, the present invention has the following advantages: the present invention can increase the heat conduction area by arranging a liquid storage tank, an inner heat dissipation fin plate and an outer heat dissipation fin plate, and utilizes a push plate to reciprocately push the coolant in the liquid storage tank, and the guidance of a guide cylinder can enable the coolant in the liquid storage tank to flow fully, thereby making the heat conduction more uniform and improving the heat dissipation efficiency.

The two parts are coaxially fixed with an internal gear 7 and an external gear 8 in sequence, and vertical support frames 9 are placed in the two support cylinders 4 respectively. A vertical strip brush 10 is fixed to the front and rear parts of the support frame 9, and a horizontal external rack 11 is fixed to the two support frames 9 respectively. The two external racks 11 are meshed with the two external gears 8 respectively. The strip brush 10 is in contact with the surface of the filter 5. A sliding frame 12 is connected to the front and rear sliding in the cabinet 1. A horizontal mounting frame 13 is fixed in the cabinet 1. A vertical dual-axis motor 14 is fixed to the top of the mounting frame 13. The bottom of the mounting frame 13 is fixed with a vertical dual-axis motor 14. A vertical gear reduction box 15 is fixed at the end, a turbofan 16 is coaxially fixed to the upper part of the rotating shaft of the dual-axis motor 14, the input shaft of the gear reduction box 15 is coaxially fixed with the bottom of the rotating shaft of the dual-axis motor 14, and a crankshaft 17 is coaxially fixed to the output shaft of the gear reduction box 15. The connecting rod journal of the crankshaft 17 is gap-inserted with the sliding frame 12, and the connecting rod journal of the crankshaft 17 can move left and right along the sliding frame 12. The left and right parts of the sliding frame 12 are each slidably connected to a horizontal moving frame 18, and the parts of the two moving frames 18 that are away from each other are respectively fixed with horizontal internal gears. Strip 19, the two movable frames 18 are connected to the sliding frame 12 respectively through an elastic member No. 1, and vertical lower baffles 20 are installed at the bottom of the two movable frames 18 through sliding members. The lower baffles 20 can move left and right compared with the movable frame 18 through the sliding members. The two lower baffles 20 are connected to the sliding frame 12 through an elastic member No. 2, and a driving component 21 is fixed to the bottom of the cabinet 1, and the driving component 21 can drive the two lower baffles 20 away from each other, and the cabinet 1 and the sliding frame 12 are jointly installed with a heat dissipation component 22, and a ventilation component 23 is installed on the top of the cabinet 1.

[0025] The bottom of the support tube 4 is inclined outward and downward, which is conducive to the discharge of dust removed by the strip brush 10 when cleaning the filter screen 5.

[0026] The ventilation assembly 23 includes a ventilation tube 24, an interception net 25, a rain cap 26, a fixing frame 27, a heat-conducting cylinder 28, a piston 29, and an upper baffle 30. The top of the cabinet 1 is fixedly connected with a vertical ventilation tube 24, and the upper penetration of the ventilation tube 24 is sealed and fixed with an interception net 25. The upper part of the ventilation tube 24 is fixed with a rain cap 26, which is used to prevent rain from scouring the interception net 25. The top of the inner wall of the cabinet 1 is fixed with a fixing frame 27, and the top of the fixing frame 27 is fixed with a heat-conducting cylinder 28. The heat-conducting cylinder A vertical piston 29 is sealed and slidably connected up and down in the body 28, and air is stored in the closed space between the piston 29 and the heat-conducting cylinder body 28. A horizontal upper baffle 30 is fixed to the piston 29 rod on the top of the piston 29. The heat-conducting cylinder body 28 is made of metal, which can improve the heat conduction efficiency. After the heat-conducting cylinder body 28 is heated, the air inside it can expand and push the piston 29 to slide upward, thereby moving the upper baffle 30 upward. When the upper baffle 30 moves upward to a certain height, it can block and close the interception net 25.

[0027] The driving assembly 21 includes a bidirectional electric push rod 31 and a roller 32. A horizontal bidirectional electric push rod 31 is fixed at the bottom of the cabinet 1. The left and right push rods of the bidirectional electric push rod 31 are rotatably connected to rollers 32. The two rollers 32 can respectively roll and rub with the two lower baffles 20. The front and back rolling friction between the rollers 32 and the lower baffles 20 facilitates the forward and backward movement of the lower baffles 20 compared to the lower baffles 20. When the bidirectional electric push rod 31 is extended, the rollers 32 can The two lower baffles 20 are pushed away from each other to close the two filter screens 5. When the two lower baffles 20 are away from each other, the two movable frames 18 are able to move away from each other under the elastic action of the second elastic member and the first elastic member. When the two movable frames 18 move away from each other to a certain extent, the inner rack 19 can mesh with the inner gear 7. When the two-way electric push rod 31 retracts the push rod, the two lower baffles 20 are able to move closer to each other under the elastic action of the first elastic member and the second elastic member to release the closure of the two filter screens 5.

[0028] The No. 1 elastic member is a No. 1 tension spring 33, and the adjacent ends of the two movable frames 18 are respectively fixed with horizontal No. 1 tension springs 33, and the ends of the two No. 1 tension springs 33 are respectively fixed to the sliding frame 12, and the two movable frames 18 have a tendency to approach each other under the elastic tension of the No. 1 tension spring 33. The No. 2 elastic member is a No. 2 tension spring 34, and the adjacent ends of the two lower baffles 20 are respectively fixed with two horizontal No. 2 tension springs 34, and the ends of the No. 2 tension springs 34 are fixed to the sliding frame 12, and the two lower baffles 20 have a tendency to approach each other under the elastic tension of the No. 2 tension spring 34, and the sliding frame 12 is a lower light rod 35, and the adjacent ends of the two lower baffles 20 are respectively fixed with horizontal lower light rods 35, and the two lower light rods 35 are respectively connected to the movable frame 18 for left and right sliding.

[0029] The heat dissipation assembly 22 includes a liquid storage tank 36, a mounting plate 37, a mounting rail 38, an inner heat dissipation fin plate 39, an outer heat dissipation fin plate 40, an upper polishing rod 41, and a push plate 42. The left and right parts of the cabinet 1 are each fixed with a metal liquid storage tank 36, and the turbofan 16 is located between the two liquid storage tanks 36. The opposite parts of the two liquid storage tanks 36 are respectively sealed and fixed with vertical metal mounting plates 37. Liquid coolant is stored in the closed cavity formed by the liquid storage tank 36 and the mounting plate 37. The end surfaces of the two mounting plates 37 facing each other are respectively fixed with multiple horizontal mounting rails 38. The two mounting plates 37 are adjacent to each other. The end faces are respectively fixed with a plurality of horizontal inner heat dissipating fins 39 made of metal, and the inner heat dissipating fins 39 are located in the liquid storage tank 36. The outer walls of the two liquid storage tanks 36 are respectively fixed with a plurality of vertical outer heat dissipating fins 40 made of metal. The left and right parts of the sliding frame 12 are respectively fixed with a group of horizontal polishing rods 41, and the two polishing rods 41 form a group. The two groups of polishing rods 41 are respectively fixed with vertical push plates 42, and the polishing rods 41 are sealed and slidably connected with the liquid storage tank 36 front and back. The push plates 42 are located in the liquid storage tank 36, and the push plates 42 are gap-connected with the liquid storage tank 36 and the inner heat dissipating fins 39.

[0030] The push plate 42 is fixed with a plurality of downwardly inclined guide cylinders 43, and the inner cavity of each guide cylinder 43 passes through the push plate 42 front to back. When the inclined guide cylinder 43 moves back and forth with the push plate 42, it can guide the coolant to move up and down, so that the coolant is fully mixed and heated evenly.

[0031] An upper water tank 44 is fixed to the upper outer portion of the cabinet 1, and a lower water tank 45 is fixed to the lower outer portion of the cabinet 1. The upper water tank 44 is connected to the upper inner cavity of the liquid storage tank 36 through a metal pipe, and the lower water tank 45 is connected to the bottom inner cavity of the liquid storage tank 36 through a metal pipe. Each of the metal pipes is sealed and filled with solid paraffin. Liquid coolant is stored in the upper water tank 44. At room temperature, the paraffin is in a solid state, thereby preventing the coolant from flowing among the upper water tank 45, the liquid storage tank 36 and the lower water tank 45. When the temperature reaches 47°C-64°C, it will melt, thereby facilitating the coolant to flow among the upper water tank 45, the liquid storage tank 36 and the lower water tank 45.

[0032] A temperature sensor 46 and a controller 47 are installed in the cabinet 1. The controller 47 is a known prior art, such as a single-chip microcomputer. The dual-axis motor 14, the bidirectional electric push rod 31, the temperature sensor 46 and the controller 47 are electrically connected. The controller 47 is externally connected to a power supply. When the dual-axis motor 14 is powered on and rotated, it can drive the turbofan 16 to rotate. When the dual-axis motor 14 is powered on and rotated, it can drive the crankshaft 17 to rotate slowly through the gear reduction box 15. When the crankshaft 17 rotates, it can drive the sliding frame 12 to slide back and forth. When the sliding frame 12 slides back and forth, it can drive the push plate 42 to move back and forth along the liquid storage tank 36 through the upper polishing rod 41.

[0033] The temperature sensor 46 is located at the upper part of the cabinet 1, so as to facilitate timely sensing of high temperature, and the controller 47 is located at the bottom of the cabinet 1, so as to reduce the interference of high temperature thereon.

[0034] The working principle of the present invention is as follows: when in use, the electrical appliance is installed on the mounting rail 38, and the cable is passed through the threading hole 3 to connect to the external power grid. After the connection is completed, the gap between the threading hole 3 and the cable is filled and sealed with a filling object. The heat generated by the electrical appliance can be transferred to the coolant through the mounting plate 37 and the internal heat dissipation fin plate 39, and further transferred to the liquid storage tank 36 and the external heat dissipation fin plate 40.

[0035] During normal heat dissipation, the temperature in the cabinet 1 is relatively low, the piston 29 is at a lower position than the heat-conducting cylinder 28, the upper baffle 30 does not block and seal the interception net 25, and the paraffin remains solid. The liquid between the upper water tank 44, the liquid storage tank 36 and the lower water tank 45 does not circulate. At this time, the dual-axis motor 14 keeps rotating, and the bidirectional electric push rod 31 is in a retracted state. At this time, the roller 32 does not roll and rub with the lower baffle 20, the inner rack 19 does not mesh with the inner gear 7, and the lower baffle 20 does not block and seal the filter 5. At this time, the rotating turbofan 16 can suck the air below and transport it upward, thereby It is able to draw external air into the cabinet 1 through the filter 5, and then pass between the two liquid storage tanks 36 and be discharged from the interception net 25. When passing between the liquid storage tanks 36, the air can exchange heat with the external heat dissipation fins 40, thereby achieving a heat dissipation effect. The dual-axis motor 14 will drive the crankshaft 17 to rotate through the gear reduction box 15, so as to drive the sliding frame 12 to slide back and forth by the crankshaft 17, and then the upper polishing rod 41 can be used to drive the push plate 42 to move back and forth in the liquid storage tank 36, so as to push the coolant back and forth, and then the coolant can be heated evenly, which is beneficial to cooling and heat dissipation.

[0036] When the filter 5 is clogged, the air entering the cabinet 1 is reduced, thereby weakening the heat dissipation effect, which will cause the temperature in the cabinet 1 to rise. At this time, the temperature sensor 46 senses that the temperature has reached the threshold value and will control the two-way electric push rod 31 to slightly extend the push rod, so that under the action of the No. 1 tension spring 33 and the No. 2 tension spring 34, the two moving frames 18 are much farther away from the sliding frame 12, and the lower baffle 20 is slightly farther away from the moving frame 18. At this time, the inner rack 19 is meshed with the inner gear 7, and the lower baffle 20 does not block and close the filter 5. At this time, the back and forth sliding of the sliding frame 12 can make the inner rack 19 move back and forth, so that the support frame 9 can be moved back and forth by using the internal gear 7, the support shaft 6, the external gear 8 and the external rack 11, and then the filter 5 can be brushed and cleaned with the strip brush 10 to restore the ventilation effect.

[0037] When a circuit failure occurs in the electrical appliance in the cabinet 1, causing the temperature in the cabinet 1 to rise abnormally, the temperature sensor 46 senses that the temperature has reached the threshold value and controls the dual-axis motor 14 to stop rotating, disconnects the circuit of the electrical appliance, and controls the bidirectional electric push rod 31 to extend the push rod heavily, so that the two lower baffles 20 are greatly separated from each other, so that the lower baffle 20 blocks and closes the filter screen 5, and the sharp increase in temperature causes the volume of the air in the heat-conducting cylinder 28 to expand greatly, so that the piston 29 extends upward greatly, and then the upper baffle 30 The interception net 25 is blocked and closed. At this time, the air in the cabinet 1 is not circulated with the outside air. After the oxygen in the cabinet 1 is consumed, the oxygen can be isolated. The increase in temperature will cause the solid paraffin to melt, so that the high-temperature coolant in the liquid storage tank 36 can be discharged into the lower water tank 45, and the low-temperature coolant in the upper water tank 44 can be discharged into the liquid storage tank 36, and then the cabinet 1 can be quickly cooled, so that the fire can be controlled in time, and even the fire can be stopped before the abnormally high temperature causes the electrical appliance to burn, so as to reduce economic losses.

[0038] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
