Technical Field

[0001] This invention relates to the field of reactive power compensation controller chassis technology, specifically a combined reactive power compensation controller chassis. Background Technology

[0002] The modular reactive power compensation controller enclosure is the external structure used to install and protect the various components of the modular reactive power compensation control system.

[0003] Patent publication number CN208062571U relates to a combined reactive power compensation controller chassis, including a left side panel, a right side panel, a front side panel, and a rear side panel. Connecting plates are fixedly connected to both sides of the front and rear side panels. A first groove is formed on the top surface of both the left and right side panels. One end of each connecting plate is inserted into the first groove. This patent solves the problem of high cost and difficult manufacturing, leading to low production efficiency of reactive power compensation controller chassis. By setting up a left side panel, right side panel, front side panel, rear side panel, connecting plate, first groove, second groove, first bolt, third groove, nut, first fixing block, and second bolt, and then fixing the first fixing block with the second bolt, the left side panel, right side panel, front side panel, and rear side panel are combined together to form the four side panels of the chassis, and are firmly fixed.

[0004] In the aforementioned patent, the first fixing block is fixed by the first fixing block and the second bolt, and then the first fixing block is fixed by the second bolt, so that the left side plate, right side plate, front side plate and rear side plate are combined together to form the four side plates of the chassis and are firmly fixed. However, the power cord inside the controller is too messy, which will affect the heat dissipation and ventilation inside the chassis, causing some components to fail to operate normally. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a combined reactive power compensation controller chassis, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a combined reactive power compensation controller chassis, including an outer shell, a power distribution cabinet fixedly installed on the surface of the outer shell, a reactive power compensation device installed inside the outer shell, a partition fixedly installed inside the outer shell, a power supply device installed inside the outer shell, a winding device and a sealing device installed inside the outer shell, and a protective device installed on the surface of the outer shell.

[0007] The winding device includes: a power cord, a servo motor, an I-beam reel, a fixed arc rod, a U-shaped rod, a sliding vertical rod, an arc rod, a sliding column, a limit block, a limit baffle, and a detection device. The power supply devices are electrically connected to each other via power cords, and are also electrically connected to the power distribution cabinet via power cords. The servo motor is fixedly installed on the bottom inner wall of the housing, and its output end rotates through the inner and outer walls of the partition. The I-beam reel is rotatably installed on the top of the partition, the fixed arc rod is rotatably installed on the surface of the I-beam reel, the U-shaped rod is fixedly installed on the inner wall of the housing, and the sliding vertical rod is slidably installed. On the inner wall of the U-shaped rod, the arc-shaped rod is fixedly installed on the top of the sliding vertical rod, the sliding column is slidably installed on the inner wall of the outer shell, the sliding column is fixedly installed on the top of the arc-shaped rod, the limiting block is fixedly installed on the bottom of the I-beam wheel, the limiting baffle is fixedly installed on the side of the sliding vertical rod near the I-beam wheel, the detection device is set on the top of the inner wall of the outer shell, the detection device is electrically connected to the servo motor, the reverse rotation of the I-beam wheel will drive the fixed arc rod to rotate, the rotation of the fixed arc rod will drive the power line to stretch, so that in the face of extreme weather, the output end of the servo motor will rotate slightly in the opposite direction and stretch the tightened power line.

[0008] According to the above technical solution, a first spring is provided between the sliding column and the outer shell, and the power line is in contact with the sliding column, so that the sliding column is reset by the first spring.

[0009] According to the above technical solution, the sealing device includes: a transmission triangle, a baffle, a square block, a transmission vertical rod, and an elastic telescopic rod. A ventilation opening is provided on the surface of the outer shell. The square block is fixedly installed on the top of the inner wall of the outer shell. The transmission vertical rod is slidably installed on the inner wall of the square block. The transmission triangle is fixedly installed on the side of the transmission vertical rod that is close to each other. The baffle is rotatably installed on the inner wall of the outer shell, with its two rotating ends rotatably installed on the side of the transmission vertical rod that is close to each other. The fixed end of the elastic telescopic rod is rotatably installed on the surface of the I-beam wheel, and the free end of the elastic telescopic rod is slidably installed on the inner wall of the outer shell. Movement of the transmission triangle will cause the transmission vertical rod to move upwards, and movement of the transmission vertical rod will cause the baffle to rotate towards the ventilation opening. The rotation of the baffle will block the ventilation opening.

[0010] According to the above technical solution, the sealing device further includes: an inclined block, a connecting rod, and a sealing plate. The inclined block is slidably mounted on the inner wall of the housing, the connecting rod is rotatably mounted on the inner wall of the housing, and the sealing plate is slidably mounted on the inner wall of the housing. One end of the connecting rod is rotatably mounted on the side of the inclined block near the sealing plate. The other end of the connecting rod is rotatably mounted on the end of the sealing plate near the inclined block. The rotation of the connecting rod will cause the sealing plate to move to the bottom, and the moving sealing plate will contact the baffle.

[0011] According to the above technical solution, a torsion spring is provided between the connecting rod and the sealing plate, and the elastic telescopic rod is in contact with the transmission triangle, thereby driving the sealing plate to reset through the torsion spring.

[0012] According to the above technical solution, the protective device includes: a protective door, an L-shaped rod, a door lock, and a square plate. The protective door is rotatably mounted on the surface of the outer shell. The L-shaped rod is fixedly mounted on the side of the transmission vertical rod near the protective door. The door lock is fixedly mounted on the side of the protective door near the outer shell. The square plate is slidably mounted on the bottom of the door lock. The square plate cannot rotate outward, so that the protective door cannot be opened, thus providing double protection for the protective door in extreme weather conditions.

[0013] According to the above technical solution, the protective device includes: a rotating long rod, a handle, a reset plate, and a transmission round rod. The rotating long rod rotates through the inner and outer walls of the protective door. The handle is fixedly installed at one end of the rotating long rod, and the reset plate is fixedly installed at the other end of the rotating long rod. The transmission round rod is fixedly installed on the side of the square plate near the reset plate. The movement of the transmission round rod will drive the square plate to move. After the square plate moves, it will no longer be in contact with the L-shaped rod, so that the protective door can be opened through a special unlocking method.

[0014] According to the above technical solution, the reset plate contacts the transmission rod, and a second spring is provided between the rotating rod and the protective door. The second spring drives the rotating rod to reset.

[0015] This invention provides a combined reactive power compensation controller chassis. It has the following advantages:

[0016] (1) In this invention, the rotation of the fixed arc rod will drive the power cord to rotate and be wound up, preventing multiple power cords from being placed messily inside the shell, which would prevent the air inside the shell from circulating and cause the device inside the shell to not be able to dissipate heat effectively, thus improving the protection effect of the device. After the limit baffle contacts the limit block, the limit block can no longer rotate, so that the I-beam wheel cannot rotate, and the I-beam wheel can no longer be wound up after the power cord is wound up, preventing excessive winding from causing the connection between the power cord and the distribution cabinet or power supply device to break, thus preventing the device from working properly and improving the stability of the device during operation. The output end of the servo motor will rotate slightly in the opposite direction and stretch the tightened power cord, preventing the device from shaking in extreme weather and causing the power cord to break in the tightened state, thus further improving the protection effect of the device.

[0017] (2) In this invention, the movement of the transmission rod will cause the baffle to rotate towards the vent. The rotation of the baffle will block the vent, preventing rainwater or impurities from flowing back into the shell under extreme weather conditions, causing the shell to lose insulation, resulting in the device discharging or leaking electricity, thus improving the safety of the device. The movement of the sealing plate will contact the baffle and block and seal the contact point between the baffle and the vent, further improving the sealing effect of the baffle.

[0018] (3) The invention prevents the protective door from being opened by the square plate being unable to rotate outwards, thus providing double protection for the protective door in extreme weather conditions. This prevents the internal components of the outer casing from being exposed to rainwater and damaged when the protective door is opened. The protective door can be opened by the square plate no longer contacting the L-shaped rod after it moves. The protective door can be opened under special circumstances by a special unlocking method. The protective door cannot be opened by pulling or rotating it by a single motion, thus improving the practicality of the device. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1 - Figure 4 One embodiment of the present invention is: a combined reactive power compensation controller chassis, including a shell 1, a power distribution cabinet 2 fixedly mounted on the surface of the shell 1, a reactive power compensation device 3 disposed inside the shell 1, a partition 4 fixedly mounted inside the shell 1, a power supply device 5 disposed inside the shell 1, and a winding device disposed inside the shell 1. The winding device includes: a power cord 61, a servo motor 62, a bobbin 63, a fixed arc rod 64, a U-shaped rod 65, a sliding vertical rod 66, an arc rod 67, a sliding column 68, a limit block 69, a limit baffle 610, and a detection device 611. The power supply devices 5 are electrically connected to each other via the power cord 61, and the power supply devices 5 are electrically connected to the power distribution cabinet 2 via the power cord 61. The servo motor 62 is fixedly mounted on the bottom of the inner wall of the shell 1, and the output end of the servo motor 62 rotates through the inner and outer walls of the partition 4. The bobbin 63 is rotatably mounted on the top of the partition 4, and the fixed arc rod 64 is rotatably mounted on the surface of the bobbin 63 to prevent multiple power cords 61 from being placed haphazardly in the shell 1. The internal structure of the casing 1 prevents air circulation, hindering effective heat dissipation for the internal components. To enhance protection, a U-shaped rod 65 is fixedly mounted on the inner wall of the casing 1, a sliding vertical rod 66 is slidably mounted on the inner wall of the U-shaped rod 65, an arc-shaped rod 67 is fixedly mounted on the top of the sliding vertical rod 66, a sliding column 68 is slidably mounted on the inner wall of the casing 1, and a sliding column 68 is fixedly mounted on the top of the arc-shaped rod 67. A limiting block 69 is fixedly mounted on the bottom of the I-beam wheel 63, and a limiting baffle 610 is fixedly mounted on the side of the sliding vertical rod 66 near the I-beam wheel 63 to prevent excessive winding from causing the power cord 61 to disconnect from the distribution cabinet 2 or power supply device 5, thus preventing the device from malfunctioning and improving its stability during operation. A detection device 611 is located on the top of the inner wall of the casing 1 and is electrically connected to the servo motor 62 to prevent the power cord 61 from disconnecting in the tightened state due to shaking of the entire device during extreme weather conditions, further enhancing the device's protective effect.

[0029] A first spring is provided between the sliding post 68 and the outer casing 1. The power cord 61 is in contact with the sliding post 68, and the first spring drives the sliding post 68 to reset.

[0030] In this embodiment, during operation: the fixed arc rod 64 is rotated upwards, and then the power cord 61 is placed at the bottom of the fixed arc rod 64. The fixed arc rod 64 is then rotated downwards, fixing the power cord 61. The servo motor 62 is started, and the output of the servo motor 62 rotates, causing the I-beam wheel 63 to rotate. The I-beam wheel 63 rotates, causing the fixed arc rod 64 to rotate, which in turn rotates the power cord 61 and winds it up. This prevents multiple power cords 61 from being haphazardly placed inside the housing 1, hindering airflow and heat dissipation, thus improving the protection of the device. After the power cord 61 is wound up, the tightened power cord moves the sliding column 68 upwards. The sliding column 68 moves the arc rod 67 upwards, which in turn moves the sliding vertical rod 66 upwards. The sliding vertical rod 66 moves the limiting baffle 610 upwards. When the 10-moving device contacts the limit block 69, the limit block 69 can no longer rotate after the limit baffle 610 contacts the limit block 69, preventing the H-beam wheel 63 from rotating. This prevents the H-beam wheel 63 from continuing to rewind after the power cord 61 has finished winding, thus preventing over-winding from causing the connection between the power cord 61 and the distribution cabinet 2 or power supply device 5 to break and causing the device to malfunction. This improves the stability of the device during operation. When the detection device 611 detects rain or strong winds outside the casing 1, the detection device 611 starts the servo motor 62. The reverse rotation of the output end of the servo motor 62 will drive the H-beam wheel 63 to reverse, which will drive the fixed arc rod 64 to rotate. The rotation of the fixed arc rod 64 will cause the power cord 61 to stretch. In the face of extreme weather, the output end of the servo motor 62 will rotate slightly in the opposite direction and stretch the tightened power cord 61, preventing the device from shaking and causing the power cord 61 to break in the tightened state during extreme weather, further improving the protective effect of the device.

[0031] Please see Figure 1 - Figure 7Based on the above embodiments, in another embodiment of the present invention, a sealing device is provided inside the outer shell 1, and a protective device is provided on the surface of the outer shell 1. The sealing device includes: a transmission triangle 71, a baffle 72, a square block 73, a transmission vertical rod 74, and an elastic telescopic rod 75. A ventilation opening is provided on the surface of the outer shell 1. The square block 73 is fixedly installed on the top of the inner wall of the outer shell 1. The transmission vertical rod 74 is slidably installed on the inner wall of the square block 73. The transmission triangle 71 is fixedly installed on the side of the transmission vertical rod 74 that is close to each other. The baffle 72 is rotatably installed on the inner wall of the outer shell 1. The two ends of the baffle 72 are rotatably installed on the side of the transmission vertical rod 74 that is close to each other. The fixed end of the elastic telescopic rod 75 is rotatably installed on the surface of the I-beam wheel 63. The free end of the elastic telescopic rod 75 is slidably installed on the inner wall of the outer shell 1. This prevents rainwater or impurities from flowing back into the interior of the outer shell 1 under extreme weather conditions, which could cause the outer shell 1 to lose its insulation, resulting in discharge or leakage of the device, thus improving the safety of the device.

[0032] The sealing device also includes: a bevel block 76, a connecting rod 77, and a sealing plate 78. The bevel block 76 is slidably mounted on the inner wall of the housing 1, the connecting rod 77 is rotatably mounted on the inner wall of the housing 1, and the sealing plate 78 is slidably mounted on the inner wall of the housing 1. One end of the connecting rod 77 is rotatably mounted on the side of the bevel block 76 near the sealing plate 78. The other end of the connecting rod 77 is rotatably mounted on the end of the sealing plate 78 near the bevel block 76. The baffle 72 blocks and seals the contact point between itself and the vent, further improving the sealing effect of the baffle 72.

[0033] A torsion spring is provided between the connecting rod 77 and the sealing plate 78. The elastic telescopic rod 75 contacts the transmission triangle 71, and the sealing plate 78 is reset through the torsion spring.

[0034] The protective device includes a protective door 81, an L-shaped rod 82, a door lock 83, and a square plate 84. The protective door 81 is rotatably mounted on the surface of the housing 1. The L-shaped rod 82 is fixedly mounted on the side of the transmission vertical rod 74 near the protective door 81. The door lock 83 is fixedly mounted on the side of the protective door 81 near the housing 1. The square plate 84 is slidably mounted on the bottom of the door lock 83 to prevent the protective door 81 from being opened and causing the internal devices of the housing 1 to be exposed to rainwater and thus damaged.

[0035] The protective device includes a rotating long rod 85, a handle 86, a reset plate 87, and a transmission round rod 88. The rotating long rod 85 rotates through the inner and outer walls of the protective door 81. The handle 86 is fixedly installed at one end of the rotating long rod 85, the reset plate 87 is fixedly installed at the other end of the rotating long rod 85, and the transmission round rod 88 is fixedly installed on the side of the square plate 84 near the reset plate 87. This allows the protective door 81 to be opened under special circumstances, and the protective door 81 cannot be opened by pulling or rotating it alone, thus improving the practicality of the device.

[0036] The reset plate 87 contacts the transmission rod 88, and a second spring is installed between the rotating rod 85 and the protective door 81. The second spring drives the rotating rod 85 to reset.

[0037] In this embodiment, during operation: the rotation of the H-beam wheel 63 causes the fixed end of the elastic telescopic rod 75 to rotate. This rotation causes the free end of the elastic telescopic rod 75 to move towards the U-shaped rod 65. The free end of the elastic telescopic rod 75 then contacts the transmission triangle 71. This movement causes the transmission triangle 71 to move upwards. The movement of the transmission triangle 71 then causes the transmission vertical rod 74 to move upwards. The movement of the transmission vertical rod 74 causes the baffle 72 to rotate towards the ventilation opening. This rotation of the baffle obstructs the ventilation opening. The baffle 72 prevents rainwater or impurities from flowing back into the housing 1 under extreme weather conditions, which could cause the housing 1 to lose its insulation, leading to discharge or leakage of the device and improving the safety of the device. When the baffle 72 rotates, it will contact the inclined block 76. The rotation of the baffle 72 will drive the inclined block 76 to move to the bottom. The movement of the inclined block 76 will drive the connecting rod 77 to rotate. The rotation of the connecting rod 77 will drive the sealing plate 78 to move to the bottom. The movement of the sealing plate 78 will contact the baffle 72 and block and seal the contact point between the baffle 72 and the vent, further improving the sealing effect of the baffle 72.

[0038] Moving the transmission vertical rod 74 upwards will cause the L-shaped rod 82 to move upwards as well. After moving, the L-shaped rod 82 will contact the square plate 84. Once in contact with the square plate 84, the square plate 84 will block the L-shaped rod 82, preventing it from rotating outwards. This prevents the protective door 81 from opening, thus providing a double limit on the protective door 81 in extreme weather conditions. This prevents the internal components of the outer casing 1 from being exposed to rain and damaged if the protective door 81 is opened. Manually pulling the handle 86 will cause the rotating rod 85 to move away from the outer casing 1. The movement of the rotating rod 85 will activate the reset plate. The door lock 83 moves in the direction of 87, and then the handle 86 is rotated. The rotation of the handle 86 will drive the rotating rod 85 to rotate, which will drive the reset plate 87 to rotate. The rotation of the reset plate 87 will make contact with the transmission rod 88. The rotation of the reset plate 87 will drive the transmission rod 88 to move, which will drive the square plate 84 to move. After the square plate 84 moves, it will no longer be in contact with the L-shaped rod 82, so that the protective door 81 can be opened. Through a special unlocking method, the protective door 81 can be opened under special circumstances. Pulling or rotating alone will not open the protective door 81, thus improving the practicality of the device.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
