Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinets, specifically relating to a power distribution cabinet with temperature regulation function. Background Technology

[0002] Distribution cabinets with temperature regulation functions are mainly built to ensure the safe and stable operation of electrical equipment. They use high-precision temperature sensors to monitor the internal temperature of the distribution cabinet in real time and precisely drive the fans to cool down and heat up, thus solving the long-standing problems of high-temperature aging and low-temperature condensation that have plagued the operation of power systems.

[0003] Patent CN116683333B discloses a power distribution cabinet with temperature regulation function, including a power distribution cabinet shell, a heat preservation device, and a heating device. The heat preservation device includes a spiral shaft fixedly connected to the inner wall of a stepper motor, a spiral shaft fixed to the drive shaft of the stepper motor, a guide sleeve fixed to the power distribution cabinet shell, a sealing flexible plate sliding in the guide sleeve, a stabilizing plate fixed to the top of the power distribution cabinet shell, an electric fan fixed to the stabilizing plate, an exhaust plate fixed to the top front of the power distribution cabinet shell, a strip-shaped pusher fixed to the side of the sealing flexible plate near the spiral shaft, and a temperature sensor fixed to the inner wall of the power distribution cabinet shell. The guide sleeve is located on both sides of the spiral shaft. This patent has the characteristics of strong practicality and the ability to work in a targeted manner at different temperatures.

[0004] Because the internal temperature of the power distribution cabinet is not uniform when adjusting the temperature, the temperature in the area where the high-voltage circuit breaker is energized is often higher, while the temperature at the bottom of the cabinet is often lower. This uneven temperature adjustment can lead to short circuits or moisture buildup, significantly shortening the cabinet's lifespan. Furthermore, if the drying process is too slow, moisture can accumulate inside the high-voltage circuit breaker, causing it to short-circuit. Additionally, the cabinet can easily compress the calcium chloride blocks during dehumidification, potentially damaging them. Summary of the Invention

[0005] The purpose of this invention is to provide a power distribution cabinet with temperature regulation function to solve the problem that the power distribution cabinet may short-circuit or become damp when it is running for a long time and the temperature regulation is uneven, which will lead to a significant reduction in the service life of the power distribution cabinet.

[0012] In one or more embodiments of the present invention, the dehumidification device includes: a frame plate, the frame plate being fixedly installed on the front side of the strip shell; A bracket, which is fixedly installed on the front side of the frame plate; Two concave plates are fixed to the top surface of the bracket. Calcium chloride blocks are fixed to the bottom of the inner ends of two concave plates. The concave plates drive the calcium chloride blocks to move up and down repeatedly, allowing the calcium chloride blocks to come into large-area contact with the air in the cabinet. The calcium chloride block is used to accelerate the drying of the inside of the drying cabinet.

[0013] In one or more embodiments of the present invention, a concave block is fixed on both sides of the front of the bracket, a curved plate is fixed on the bottom surface of each of the two concave blocks, a concave arc plate is fixed at the ends of the two curved plates that are far apart from each other, a roller is rotatably installed on the inner wall of each of the two concave arc plates, the outer wall of the two rollers rolls in contact with the inner wall of the cabinet, and the concave arc plates drive the rollers to move up and down reciprocally, and the rollers roll up and down reciprocally in the cabinet.

[0014] In one or more embodiments of the present invention, the protective device includes: an L-shaped plate, the L-shaped plate being fixed to the outer walls of two curved plates respectively; Vertical columns, which are respectively fixed to the top surfaces of the two L-shaped plates; U-shaped strip, the U-shaped strip being fixed to the front of the vertical column; Two U-shaped guard plates are fixed to the back of the U-shaped strip and are located in front of the two calcium chloride blocks respectively. The U-shaped strip drives the U-shaped guard plates to move up and down reciprocally. The U-shaped guard plate is used to abut against the lower chamber of the cabinet, and the two U-shaped guard plates are used to prevent the two calcium chloride blocks from being squeezed against the top of the lower chamber of the cabinet.

[0015] In one or more embodiments of the present invention, a U-shaped connecting block is fixed in the middle of the back side of the U-shaped strip, a pressure plate is rotatably installed on the inner wall of the U-shaped connecting block, an arc-shaped spring is fixed on the outer wall of the rotating shaft of the pressure plate, and one end of the arc-shaped spring away from the rotating shaft of the pressure plate is fixedly connected to the front side of the U-shaped strip. When the U-shaped connecting block moves downward, the hose deforms and abuts against the pressure plate. The rotating shaft of the pressure plate rotates upward in the U-shaped connecting block, the arc-shaped spring deforms, and when the U-shaped connecting block moves upward, the arc-shaped spring returns to its original position. The rotating shaft of the pressure plate rotates downward in the U-shaped connecting block, and the pressure plate bends against the hose.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention uses a cabinet, a high-voltage circuit breaker, a temperature sensor, a resistance heater, an electric fan, a cover, a hose, a servo motor, a threaded rod, an inner spiral tube, and a strip shell in conjunction with a mesh frame. The electric fan delivers hot or cold air to the cover, the cover delivers hot or cold air to the hose, and the hose delivers hot or cold air to the strip shell. The output shaft of the servo motor drives the threaded rod to rotate back and forth. Under the constraint of the threaded rod, the inner spiral tube moves up and down in the thread groove of the threaded rod. The inner spiral tube drives the strip shell to move up and down. The strip shell guides the hot or cold air to blow into the cabinet, so that the temperature inside the cabinet is balanced. This prevents the risk of short circuit or moisture in the power distribution cabinet due to uneven temperature regulation, which would greatly shorten the service life of the power distribution cabinet.

[0017] (2) By setting up a dehumidification device, the frame plate, bracket and concave plate work together with the calcium chloride block. The concave plate drives the calcium chloride block to move up and down repeatedly, and the calcium chloride block comes into contact with the air in the cabinet over a large area. The calcium chloride block accelerates the drying of the moisture in the cabinet, preventing the moisture inside the cabinet from drying too slowly and causing the moisture to accumulate inside the high voltage circuit breaker, resulting in the high voltage circuit breaker becoming damp and short-circuiting.

[0018] (3) The present invention uses a dehumidification device to make the concave block, the curved plate and the concave arc plate work together with the roller. The concave arc plate drives the roller to move up and down repeatedly. The roller rolls up and down repeatedly in the cabinet. Under the restriction of the roller, the vibration of the bracket during movement is reduced, and the high vibration frequency of the bracket is prevented from causing the calcium chloride block to shake and break easily.

[0019] (4) The present invention uses a protective device to make the L-shaped plate, the vertical column and the U-shaped strip plate work together with the U-shaped guard plate. The U-shaped strip plate drives the U-shaped guard plate to move up and down repeatedly. The U-shaped guard plate is used to press against the lower cavity of the cabinet so that the calcium chloride block will not come into contact with the cabinet and prevent the cabinet from easily squeezing the calcium chloride block and causing damage to the calcium chloride block.

[0020] (5) The present invention, through the setting of the protective device, makes the U-shaped connecting block and the pressure plate cooperate with the arc-shaped spring piece. When the U-shaped connecting block moves downward, the hose deforms and abuts against the pressure plate. The rotating shaft of the pressure plate rotates upward in the U-shaped connecting block, and the arc-shaped spring piece deforms. When the U-shaped connecting block moves upward, the arc-shaped spring piece resets. The rotating shaft of the pressure plate rotates downward in the U-shaped connecting block, and the pressure plate bends against the hose, so that the hose will not get stuck in the slot of the cabinet, and prevent the hose from getting stuck in the slot of the cabinet and causing the hose to break and be damaged.

[0023] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0024] like Figure 1-9 As shown, a power distribution cabinet with temperature regulation function includes: cabinet 1, cabinet 1 has two chambers inside, cabinet door 101 is hinged to the upper right side of cabinet 1, a control console is provided on the front of cabinet door 101, cabinet door 2 102 is hinged to the lower right side of cabinet 1, air inlets 103 are provided on the upper left and right sides of cabinet 1, and exhaust outlets 104 are provided on the lower left and right sides of cabinet 1. High-voltage circuit breaker 2 is installed on the front of the lower inner wall of the cabinet 1. Temperature sensor 3 is installed on the top surface of high voltage circuit breaker 2; Resistance heater 4 is fixed at the bottom of the upper cavity of cabinet 1; Electric fan 5, the electric fan 5 is fixed on the front of the resistance heater 4; Cover 6, cover 6 is fixed to the front of the electric fan 5; Hose 7, which passes through and is fixed in the middle of the front side of the cover 6; Two servo motors 8 are fixed at the bottom of the upper cavity; Two threaded rods 9 are installed through and rotatably inside the lower cavity of the cabinet 1 at the top and bottom ends, and the top surfaces of the two threaded rods 9 are fixedly connected to the bottom surfaces of the output shafts of the two servo motors 8. The internal threaded tube 10 is slidably installed on the outer wall of the threaded rod 9. The outer walls of the two threaded rods 9 are respectively provided with non-self-locking threaded grooves, and the outer walls of the threaded grooves of the two threaded rods 9 mesh with the inner walls of the two internal threaded tubes 10. The strip shell 11 is fixed on one side of the two internal helical tubes 10 that are close to each other. The top surface of the strip shell 11 is fixedly connected to the end of the hose 7 away from the cover 6. The hose 7 is located behind the two servo motors 8 and in front of the cover 6. The strip shell 11 is located in front of the high voltage circuit breaker 2. A slot is opened at the bottom of the upper cavity of the cabinet 1. The hose 7 is located inside the slot of the upper cavity of the cabinet 1. A mesh frame 12 is installed on the inner wall of the strip shell 11. The mesh frame 12 is used to filter dust in the gas. The casing 11 is used to guide the heat flow or low-temperature gas to heat up or cool down the high-voltage circuit breaker 2; When this distribution cabinet is used indoors, cabinet 1 supports high-voltage circuit breaker 2, and high-voltage circuit breaker 2 supports temperature sensor 3. Temperature sensor 3 monitors the internal temperature of cabinet 1 in real time. When the internal temperature of cabinet 1 is too high, temperature sensor 3 activates resistance heater 4, which begins to heat up. Temperature sensor 3 also activates electric fan 5, which begins to rotate forward. Air is drawn in through air inlet 103, heated by resistance heater 4, and then delivered by electric fan 5 to housing 6. When the internal temperature of cabinet 1 is too low, electric fan 5 begins to rotate forward, drawing in air through air inlet 103 and delivering cold air to housing 6. Housing 6 then delivers hot or cold air to hose 7, which in turn delivers hot or cold air to strip housing 11. Temperature sensor 3 activates servo motor 8, whose output shaft begins to rotate in both directions. The output shaft of servo motor 8 drives threaded rod 9 to rotate in both directions. The threaded rod 9 rotates back and forth in the cabinet 1. Under the constraint of the threaded rod 9, the inner threaded tube 10 moves up and down in the thread groove of the threaded rod 9. The inner threaded tube 10 drives the strip shell 11 to move up and down, and the strip shell 11 drives the mesh frame 12 to move up and down. The mesh frame 12 filters dust in the hot or cold air. The air entering the cabinet 1 is discharged from the exhaust port 104. During the up and down movement, the strip shell 11 guides the hot or cold air to blow into the cabinet 1, so that the internal temperature of the cabinet 1 is even. This avoids the risk of short circuit or moisture in the distribution cabinet when the internal temperature of the distribution cabinet is unevenly adjusted, which would greatly shorten the service life of the distribution cabinet. The operator rotates to open the cabinet door 101 to facilitate the maintenance of the resistance heater 4. The operator rotates to open the cabinet door 202 to facilitate the maintenance of the high voltage circuit breaker 2. A dehumidification device 13 is provided on the front of the shell 11. The dehumidification device 13 is used to accelerate the drying of the inside of the cabinet 1 when cooling. A protective device 14 is provided on the outer wall of the dehumidification device 13. The protective device 14 is used to prevent the dehumidification device 13 from being squeezed when the equipment is running.

[0025] The dehumidification device 13 includes: a frame plate 131, which is fixedly installed on the front side of the strip shell 11; Bracket 132 is fixedly installed on the front side of frame plate 131; Two concave plates 133 are fixed to the top surface of the bracket 132; Calcium chloride block 134 is fixed to the bottom of the inside of two concave plates 133 respectively; Calcium chloride block 134 is used inside the accelerated drying cabinet 1; While the strip shell 11 drives the mesh frame 12 to move up and down, the strip shell 11 drives the frame plate 131 to move up and down, the frame plate 131 drives the bracket 132 to move up and down, the bracket 132 drives the concave plate 133 to move up and down, and the concave plate 133 drives the calcium chloride block 134 to move up and down. During the up and down movement of the calcium chloride block 134, the calcium chloride block 134 comes into large-area contact with the air in the cabinet 1. The calcium chloride block 134 accelerates the drying of the moisture in the cabinet 1, thereby avoiding the problem that the moisture inside the cabinet 1 will accumulate inside the high-voltage circuit breaker 2 and cause the high-voltage circuit breaker 2 to become damp and short-circuit during the process of adjusting the internal temperature of the distribution cabinet 1.

[0026] A recess 135 is fixed on both sides of the front of the bracket 132. A curved plate 136 is fixed on the bottom surface of the two recesses 135 respectively. A concave arc plate 137 is fixed at the opposite end of the two curved plates 136 respectively. A roller 138 is rotatably installed on the inner wall of the two concave arc plates 137 respectively. The outer wall of the two rollers 138 makes rolling contact with the inner wall of the cabinet 1. While the bracket 132 drives the concave plate 133 to move up and down reciprocally, the concave plate 133 drives the concave block 135 to move up and down reciprocally, the concave block 135 drives the curved plate 136 to move up and down reciprocally, the curved plate 136 drives the concave arc plate 137 to move up and down reciprocally, and the concave arc plate 137 drives the roller 138 to move up and down reciprocally. The roller 138 rolls up and down in the cabinet 1. Under the restriction of the roller 138, the vibration of the bracket 132 during movement is reduced, thereby avoiding the problem that the calcium chloride block 134 is prone to vibration and breakage due to the excessive vibration frequency of the bracket 132 during the process of adjusting the internal temperature of the cabinet 1.

[0027] The protective device 14 includes: an L-shaped plate 141, which is fixed to the outer wall of the two curved plates 136 respectively; Vertical column 142, which is fixed to the top surface of two L-shaped plates 141 respectively; U-shaped strip 143, U-shaped strip 143 is fixed to the front of vertical column 142; Two U-shaped protective plates 144 are fixed to the back of the U-shaped strip 143 and are located in front of the two calcium chloride blocks 134 respectively. Two U-shaped guards 144 are used to prevent the two calcium chloride blocks 134 from being squeezed and the top of the lower cavity of the cabinet 1; While the curved plate 136 drives the concave arc plate 137 to move up and down reciprocally, the concave arc plate 137 drives the L-shaped plate 141 to move up and down reciprocally, the L-shaped plate 141 drives the vertical column 142 to move up and down reciprocally, the vertical column 142 drives the U-shaped strip plate 143 to move up and down reciprocally, and the U-shaped strip plate 143 drives the U-shaped guard plate 144 to move up and down reciprocally. The U-shaped guard plate 144 is used to abut against the lower cavity of the cabinet 1, so that the calcium chloride block 134 will not come into contact with the cabinet 1 during the upward movement, thereby avoiding the problem that the cabinet 1 may squeeze the calcium chloride block 134 and cause damage to the calcium chloride block 134 during the process of adjusting the internal temperature of the cabinet 1.

[0028] A U-shaped connecting block 145 is fixed in the middle of the back of the U-shaped strip 143. A pressure plate 146 is rotatably installed on the inner wall of the U-shaped connecting block 145. An arc-shaped spring piece 147 is fixed on the outer wall of the rotating shaft of the pressure plate 146. One end of the arc-shaped spring piece 147 away from the rotating shaft of the pressure plate 146 is fixedly connected to the front of the U-shaped strip 143. While the U-shaped strip 143 drives the U-shaped guard plate 144 to move up and down reciprocally, the U-shaped strip 143 drives the U-shaped connecting block 145 to move up and down reciprocally. The U-shaped connecting block 145 drives the pressure plate 146 to move up and down reciprocally. The pressure plate 146 drives the arc-shaped spring piece 147 to move up and down reciprocally. When the U-shaped connecting block 145 moves downward, the flexible hose 7 deforms and abuts against the pressure plate 146. The rotating shaft of the pressure plate 146 rotates upward in the U-shaped connecting block 145. The arc-shaped spring piece 147 deforms. When the U-shaped connecting block 145 moves upward, the arc-shaped spring piece 147 returns to its original position. The rotating shaft of the pressure plate 146 rotates downward in the U-shaped connecting block 145. The pressure plate 146 bends against the flexible hose 7, preventing the flexible hose 7 from getting stuck in the slot of the cabinet 1. This avoids the problem of the flexible hose 7 getting stuck in the slot of the cabinet 1 and causing the flexible hose 7 to break and be damaged during the process of adjusting the internal temperature of the power distribution cabinet.

[0029] Working principle: When this distribution cabinet is used indoors, the temperature sensor 3 monitors the internal temperature of the cabinet 1 in real time. When the internal temperature of the cabinet 1 is too high, the air inlet 103 draws in air, and the resistance heater 4 heats the air. When the internal temperature of the cabinet 1 is too low, the electric fan 5 delivers cold air to the cover 6. The cover 6 delivers hot or cold air to the hose 7. The hose 7 delivers hot or cold air to the strip shell 11. The output shaft of the servo motor 8 drives the threaded rod 9 to rotate back and forth. The threaded rod 9 rotates back and forth in the cabinet 1. Under the restriction of the threaded rod 9, the inner thread tube 10 moves up and down in the thread groove of the threaded rod 9. The inner thread tube 10 drives the strip shell 11 to move up and down. The strip shell 11 drives the mesh frame 12 to move up and down. The mesh frame 12 filters the dust in the hot or cold air. The air entering the cabinet 1 is discharged from the exhaust port 104. The strip shell 11 guides the hot or cold air to blow into the cabinet 1. The shell 11 drives the frame plate 131 to move up and down reciprocally, the frame plate 131 drives the bracket 132 to move up and down reciprocally, the bracket 132 drives the concave plate 133 to move up and down reciprocally, the concave plate 133 drives the calcium chloride block 134 to move up and down reciprocally, and the calcium chloride block 134 comes into large-area contact with the air in the cabinet 1. The concave plate 133 drives the concave block 135 to move up and down reciprocally. The concave block 135 drives the bent plate 136 to move up and down reciprocally. The bent plate 136 drives the concave arc plate 137 to move up and down reciprocally. The concave arc plate 137 drives the roller 138 to move up and down reciprocally. The roller 138 rolls up and down in the cabinet 1. The vibration of the bracket 132 when it moves is reduced by the restriction of the roller 138. The concave arc plate 137 drives the L-shaped plate 141 to move up and down reciprocally. The L-shaped plate 141 drives the vertical column 142 to move up and down reciprocally. The vertical column 142 drives the U-shaped strip plate 143 to move up and down reciprocally. The U-shaped strip plate 143 drives the U-shaped guard plate 144 to move up and down reciprocally. The U-shaped guard plate 144 is used to abut against the lower cavity of the cabinet 1 to prevent the calcium chloride block 134 from contacting the cabinet 1. The U-shaped strip 143 drives the U-shaped connecting block 145 to move up and down reciprocally. The U-shaped connecting block 145 drives the pressure plate 146 to move up and down reciprocally. The pressure plate 146 drives the arc-shaped spring piece 147 to move up and down reciprocally. When the U-shaped connecting block 145 moves downward, the hose 7 deforms and abuts against the pressure plate 146. The pivot of the pressure plate 146 rotates upward in the U-shaped connecting block 145. The arc-shaped spring piece 147 deforms. When the U-shaped connecting block 145 moves upward, the arc-shaped spring piece 147 returns to its original position. The pivot of the pressure plate 146 rotates downward in the U-shaped connecting block 145. The pressure plate 146 bends against the hose 7.
