Description

Technical Field

[0001] This invention relates to the field of low-voltage power distribution equipment technology, specifically to a remotely controllable intelligent low-voltage power distribution device. Background Technology

[0002] The low-voltage power distribution device and control equipment is a type of low-voltage distribution cabinet, which can be used to install and protect internal electronic components.

[0003] Utility model patent CN205282920U relates to a safe low-voltage distribution cabinet, including a cabinet body and cabinet doors. The cabinet body is divided into several installation chambers by partitions. The cabinet body is equipped with a safety alarm device, a power plug, and a fault detection module. The safety alarm device includes an external alarm and an internal controller, a main power switch, branch switches, an alarm module, and a wireless signal transmission device. This utility model overcomes the shortcomings of the prior art by installing a safety alarm device above the low-voltage distribution cabinet. When a fault occurs in the low-voltage distribution, the safety alarm device sends an alarm signal to a remote server via a wireless signal transmission device. Simultaneously, an alarm light illuminates. Upon receiving the alarm signal, the remote server can, based on the fault condition, select to switch the main power switch on / off, activate the audible alarm, or dispatch personnel for on-site repair. This achieves simultaneous on-site and remote alarm operation, intelligent operation, and maximizes the safety of the low-voltage distribution cabinet. The aforementioned utility model allows for the selection of switching the main power switch on and off, activating the audible alarm, and dispatching personnel to the site for repairs, based on the fault condition, enabling simultaneous on-site and remote alarms. However, once the power supply inside the distribution cabinet is disconnected, the internal heat dissipation device becomes unusable, resulting in the inability to dissipate heat in a timely manner, which can damage the electronic components inside the distribution cabinet. Furthermore, the aforementioned distribution cabinet relies on air intake for heat dissipation, preventing the timely expulsion of high-temperature and toxic gases from the cabinet, thus affecting subsequent maintenance work. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a remotely controllable intelligent low-voltage power distribution device. This solves the problem that when the power supply inside the power distribution cabinet is disconnected, the internal heat dissipation device becomes unusable, leading to insufficient heat dissipation and potential damage to the electronic components inside the cabinet. Furthermore, the aforementioned power distribution cabinet relies on internal air intake for heat dissipation, preventing the timely expulsion of high-temperature and toxic gases, thus affecting subsequent maintenance work.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a remotely controllable intelligent low-voltage power distribution device, comprising a device body, a door panel rotatably mounted on the surface of the device body, a control switch fixedly mounted on the inner wall of the device body, a signal transmitter fixedly mounted on the top of the device body, a protective device provided on the inner wall of the device body, the protective device including a partition, the partition fixedly mounted on the inner wall of the device body, a battery fixedly mounted on the top of the inner wall of the device body, a ventilation frame fixedly mounted inside the partition, a drive device fixedly mounted on the top of the partition, a fan blade fixedly mounted on the output end of the drive device, an L-shaped plate rotatably mounted on the top of the device body, a push rod slidably mounted on the inner wall of the ventilation frame, an elastic telescopic rod fixedly mounted on the surface of the output end of the drive device, a plug rod slidably mounted on the bottom of the push rod, and a temperature control switch that transmits a signal when the internal temperature of the device body rises. When the device is turned on, the signal transmitter transmits information about the high temperature generated inside the device. Upon receiving this signal, the receiver sends a feedback signal. When the signal transmitter receives the feedback signal, it shuts off the power supply inside the device via a control switch. Simultaneously, the control switch turns on the drive device. The rotation of the elastic telescopic rod generates centrifugal force, causing the free end of the elastic telescopic rod to move away from the drive device. This causes the free end of the elastic telescopic rod to contact the insertion rod and push it to move. This movement causes the insertion rod to disengage from the bottom of the ventilation frame, releasing the insertion rod from its limiting position on the push rod. As the push rod moves upward, it pushes the L-shaped plate to rotate upward. The upward rotation of the L-shaped plate opens the top of the ventilation frame, causing the drive device to rotate the fan blades. The rotation of the fan blades expels the gas inside the device from the ventilation frame, improving the ventilation effect inside the device.

[0008] Preferably, a spring is provided between the push rod and the surface of the ventilation frame, a return spring is provided between the insert rod and the push rod, and the ends of the insert rod and the elastic telescopic rod that are close to each other are provided with an arc shape. The arc shape allows the elastic telescopic rod to push the insert rod to move when it contacts the insert rod, and the insert rod contacts the bottom of the ventilation frame.

[0009] Preferably, the battery is electrically connected to the drive device, and the drive device is electrically connected to the control switch. The control switch can turn on the drive device and provide power to the drive device through the battery.

[0010] Preferably, the surface of the drive device is provided with a flow guiding device, which includes a connecting shaft. The connecting shaft is fixedly installed at the bottom of the output end of the drive device. An arc-shaped plate is hinged to the surface of the connecting shaft, and a slide rod is hinged to the surface of the arc-shaped plate. The end of the slide rod away from the arc-shaped plate is slidably installed on the surface of the connecting shaft. An elastic plate is fixedly installed at the bottom of the slide rod. When the arc-shaped plate rotates, centrifugal force is generated, causing the arc-shaped plate to flip downwards. When the arc-shaped plate flips downwards, it can prevent the gas drawn by the fan blades from moving to the bottom of the partition, thereby improving the effect of gas moving towards the ventilation frame. Preventing the gas drawn by the fan blades from flowing to the bottom of the partition will increase the temperature around the battery, thus preventing high temperature from affecting the battery.

[0011] Preferably, a fire extinguishing device is provided on the surface of the connecting shaft. The fire extinguishing device includes a fire extinguisher, which is rotatably mounted on the bottom of the connecting shaft. A spray plate is fixedly mounted on the bottom of the fire extinguisher. An arc-shaped rod is fixedly mounted on the bottom of the arc-shaped plate. A push switch is fixedly mounted on the surface of the connecting shaft. A temperature sensing device is fixedly mounted on the inner wall of the device body. The temperature sensing device is electrically connected to the drive device. A temperature sensing module is provided inside the temperature sensing device. The temperature sensing module can contact the temperature. When the temperature rises, it can reduce the resistance between the battery and the drive device. When the rotation speed of the arc-shaped plate increases, the downward flipping range increases. Thus, when the arc-shaped plate flips downward, it will drive the arc-shaped rod to press the push switch, causing the push switch to open the fire extinguisher. The extinguishing agent inside the fire extinguisher will be sprayed out from inside the spray plate. The spraying of the extinguishing agent can prevent the electronic components inside the device body from spontaneously combusting due to high temperature. The spray plate can increase the spraying range and improve the effect of preventing spontaneous combustion.

[0012] Preferably, a torsion spring is provided between the arc-shaped plate and the connecting shaft, and the fire extinguisher is fixedly installed on the inner wall of the device body by a bracket so that the fire extinguisher will not rotate.

[0013] Preferably, the top of the device body is provided with a cooling protection device, which includes a water storage frame, a conveying pipe fixedly installed at the bottom of the water storage frame, a cooling plate fixedly installed at the bottom of the conveying pipe, a movable plate rotatably installed on the surface of the L-shaped plate, a filter plate rotatably installed on the top of the water storage frame, the movable plate contacting the top of the water storage frame, and a sealing block provided on the top of the conveying pipe. The sealing block is fixed to the filter plate by a pull rope. When the L-shaped plate rotates, it pushes the movable plate to move, and when the movable plate moves, it pushes the filter plate to rotate. When the filter plate rotates, it pulls the sealing block away from the conveying pipe by the pull rope, thereby releasing the seal on the conveying pipe and allowing rainwater inside the water storage frame to enter the interior of the cooling plate. The cooling plate can cool the area around the battery, thus protecting the battery from damage caused by excessively high ambient temperatures.

[0014] Preferably, a protrusion is fixedly installed at the bottom of the filter plate, and a spiral spring is provided between the movable plate and the L-shaped plate. When the movable plate moves, it will collide with the protrusion on the surface of the filter plate, causing the filter plate to vibrate, thus preventing excessive impurities from adhering to the filter plate and affecting the filtration effect of rainwater.

[0015] (III) Beneficial Effects

[0016] This invention provides a remotely controllable intelligent low-voltage power distribution device. It has the following advantages:

[0017] (1) When the temperature inside the device body rises, the remotely controllable intelligent low-voltage power distribution device transmits high temperature information through a control switch and a signal transmitter. After receiving the signal, the receiver transmits feedback information. When the signal transmitter receives the feedback information, the control device shuts off the power inside the device body. The control switch enables the battery to provide power to the drive device. The drive device drives the fan blades to rotate. When the fan blades rotate, the gas inside the device body is ejected from the ventilation frame, realizing the exhaust and heat dissipation function when the power is off. At the same time, the drive device drives the elastic telescopic rod to rotate. When the elastic telescopic rod rotates, it pushes the insertion rod to move, so that the insertion rod releases the limit on the push rod. The push rod moves upward and pushes the L-shaped plate to rotate upward. When the L-shaped plate rotates upward, it opens the top of the ventilation frame, thereby improving the exhaust and ventilation effect inside the device body.

[0018] (2) The remotely controllable intelligent low-voltage power distribution device will drive the arc plate to rotate. When the arc plate rotates, it will generate centrifugal force. Under the action of centrifugal force, the arc plate will rotate downward. When the arc plate rotates downward, it will press the gas inside the device body to flow towards the ventilation frame, preventing the gas drawn by the fan blades from flowing to the bottom of the partition and increasing the temperature around the battery, thus preventing high temperature from affecting the battery.

[0019] (3) The remotely controllable intelligent low-voltage power distribution device detects the internal temperature of the device body through a temperature sensing device. When the internal temperature of the device body is higher, the speed of the drive device driving the arc plate to rotate is faster, and the arc plate rotates downwards to a greater extent. The arc plate drives the arc rod to press the push switch, which opens the fire extinguisher. The fire extinguisher sprays the extinguishing agent inside from the spray plate. The spraying of the extinguishing agent can prevent the electronic components inside the device body from spontaneously combusting due to high temperature.

[0020] (4) The remotely controllable intelligent low-voltage power distribution device can collect rainwater through the water storage frame. When the L-shaped plate rotates upward, it will drive the moving plate to move. When the moving plate moves, it will push the filter plate to rotate. When the filter plate rotates, it will pull the rope and the sealing block to open the conveying pipe, so that the water inside the water storage frame will enter the interior of the cooling plate through the conveying pipe. The cooling plate can cool the area around the battery and protect the battery. When the moving plate moves, it will contact the protrusion, causing the filter plate to vibrate and avoid excessive impurities adhering to the filter plate, which will affect the filtration effect of rainwater.

[0028] 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.

[0029] Please see Figure 1-6This invention provides a technical solution: a remotely controllable intelligent low-voltage power distribution device, comprising a device body 1, a door panel 2 rotatably mounted on the surface of the device body 1, a control switch 3 fixedly mounted on the inner wall of the device body 1, a signal transmitter 4 fixedly mounted on the top of the device body 1, a protective device provided on the inner wall of the device body 1, the protective device including a partition 51 fixedly mounted on the inner wall of the device body 1, a battery 53 fixedly mounted on the top of the inner wall of the device body 1, a ventilation frame 52 fixedly mounted inside the partition 51, a drive device 54 fixedly mounted on the top of the partition 51, a fan blade 511 fixedly mounted on the output end of the drive device 54, an L-shaped plate 55 rotatably mounted on the top of the device body 1, a push rod 56 slidably mounted on the inner wall of the ventilation frame 52, an elastic telescopic rod 58 fixedly mounted on the surface of the output end of the drive device 54, and a plug rod 57 slidably mounted on the bottom of the push rod 56. The control switch 3 is a temperature control switch; when the temperature inside the device body 1 rises, the control switch 3 will open the signal transmitter 4, transmitting the signal through a signal. Transmitter 4 transmits information about the high temperature generated inside device body 1. Upon receiving this signal, the receiver transmits feedback information. When transmitter 4 receives the feedback information, it shuts off the power supply inside device body 1 via control switch 3. Simultaneously, control switch 3 activates drive device 54. The rotation of elastic telescopic rod 58 generates centrifugal force. Under this centrifugal force, the free end of elastic telescopic rod 58 moves away from drive device 54, causing the free end of elastic telescopic rod 58 to... When the insertion rod 57 contacts and pushes the insertion rod 57 to move, the insertion rod 57 will disengage from the bottom of the ventilation frame 52, and the insertion rod 57 will release the limit on the push rod 56. When the push rod 56 moves upward, it will push the L-shaped plate 55 to rotate upward. When the L-shaped plate 55 rotates upward, it will open the top of the ventilation frame 52, so that the drive device 54 will drive the fan blade 511 to rotate. When the fan blade 511 rotates, it will discharge the gas inside the device body 1 from the ventilation frame 52, which can improve the exhaust and ventilation effect inside the device body 1.

[0030] A spring is provided between the push rod 56 and the surface of the ventilation frame 52. A return spring is provided between the insertion rod 57 and the push rod 56. The ends of the insertion rod 57 and the elastic telescopic rod 58 that are close to each other are both provided with arcs. The arcs allow the elastic telescopic rod 58 to push the insertion rod 57 to move when it comes into contact with the insertion rod 57. The insertion rod 57 then contacts the bottom of the ventilation frame 52.

[0031] The battery 53 is electrically connected to the drive unit 54, and the drive unit 54 is electrically connected to the control switch 3. The control switch 3 can turn on the drive unit 54 and provide power to the drive unit 54 through the battery 53.

[0032] The drive unit 54 is provided with a flow guiding device, which includes a connecting shaft 61. The connecting shaft 61 is fixedly installed at the bottom of the output end of the drive unit 54. An arc-shaped plate 62 is hinged to the surface of the connecting shaft 61, and a slide rod 63 is hinged to the surface of the arc-shaped plate 62. The end of the slide rod 63 away from the arc-shaped plate 62 is slidably installed on the surface of the connecting shaft 61. An elastic plate 64 is fixedly installed at the bottom of the slide rod 63. The drive unit 54 can also drive the connecting shaft 61 to rotate. When the connecting shaft 61 rotates, it will drive the arc-shaped plate 62 to rotate. When the arc-shaped plate 62 rotates, it will generate centrifugal force, causing the arc-shaped plate 62 to flip downward. When the arc-shaped plate 62 flips downward, it can prevent the gas drawn by the fan blade 511 from moving to the bottom of the partition 51, thereby improving the effect of gas moving towards the ventilation frame 52. Preventing the gas drawn by the fan blade 511 from flowing to the bottom of the partition 51 will increase the temperature around the battery 53, thus preventing high temperature from affecting the battery 53.

[0033] A fire extinguishing device is provided on the surface of the connecting shaft 61, including a fire extinguisher 67. The fire extinguisher 67 is rotatably mounted on the bottom of the connecting shaft 61. A spray plate 68 is fixedly mounted on the bottom of the fire extinguisher 67. An arc rod 65 is fixedly mounted on the bottom of the arc plate 62. A push-button switch 66 is fixedly mounted on the surface of the connecting shaft 61. A temperature sensing device 69 is fixedly mounted on the inner wall of the device body 1. The temperature sensing device 69 is electrically connected to the drive device 54. A temperature sensing module is provided inside the temperature sensing device 69. The temperature sensing module can detect the temperature. When the temperature rises, it can reduce the resistance between the battery 53 and the drive device 54. The temperature sensing device 69 will... Temperature is detected, and as the temperature rises, the temperature sensing device 69 increases the working power of the drive device 54, thereby increasing the rotation speed of the fan blade 511 and the arc plate 62 driven by the drive device 54. When the rotation speed of the arc plate 62 increases, the downward flipping range increases. When the arc plate 62 flips downward, it drives the arc rod 65 to press the push switch 66, causing the push switch 66 to open the fire extinguisher 67. The extinguishing agent inside the fire extinguisher 67 will be sprayed out from inside the spray plate 68. The spraying of the extinguishing agent by the spray plate 68 can prevent the electronic components inside the device body 1 from spontaneously combusting due to high temperature. The spray plate 68 can increase the spray range and improve the effect of preventing spontaneous combustion.

[0034] A torsion spring is provided between the arc plate 62 and the connecting shaft 61. The fire extinguisher 67 is fixedly installed on the inner wall of the device body 1 by a bracket, so that the fire extinguisher 67 will not rotate.

[0035] A cooling and protection device is installed on the top of the main body 1. The cooling and protection device includes a water storage frame 71, a conveying pipe 72 fixedly installed at the bottom of the water storage frame 71, a cooling plate 73 fixedly installed at the bottom of the conveying pipe 72, a movable plate 76 rotatably installed on the surface of the L-shaped plate 55, and a filter plate 77 rotatably installed on the top of the water storage frame 71. The movable plate 76 contacts the top of the water storage frame 71. A sealing block 74 is provided on the top of the conveying pipe 72. The sealing block 74 is fixed to the filter plate 77 by a pull rope 75. The water storage frame 71 can collect rainwater and will push the L-shaped plate 55 when it rotates. The movable plate 76 moves, which pushes the filter plate 77 to rotate. When the filter plate 77 rotates, it pulls the sealing block 74 away from the delivery pipe 72 through the pull rope 75, thereby releasing the seal on the delivery pipe 72. This allows rainwater inside the water storage frame 71 to enter the interior of the cooling plate 73. The cooling plate 73 can cool the area around the battery 53, thus protecting the battery 53 from damage due to excessively high ambient temperature.

[0036] A protrusion 78 is fixedly installed at the bottom of the filter plate 77. A spiral spring is provided between the movable plate 76 and the L-shaped plate 55. When the movable plate 76 moves, it will collide with the protrusion 78 on the surface of the filter plate 77, causing the filter plate 77 to vibrate. This prevents too many impurities from adhering to the filter plate 77 and affecting the filtration effect on rainwater.

[0037] When it is necessary to protect the electronic components inside the device body 1 during operation (or use), the temperature inside the device body 1 will be detected by the control switch 3. If the temperature inside the device body 1 is too high, the control switch 3 will activate the signal transmitter 4, which will transmit information about the high temperature inside the device body 1. After receiving the signal, the receiving end will transmit feedback information. When the signal transmitter 4 receives the feedback information, the control switch 3 will turn off the power inside the device body 1 and simultaneously turn on the drive device 54. The battery 53 will provide power to the drive device 54. When the drive device 54 is working, it will drive the elastic telescopic rod 58 to rotate. When the elastic telescopic rod 58 rotates... Centrifugal force will be generated. Under the action of centrifugal force, the free end of the elastic telescopic rod 58 will move away from the drive device 54, so that the free end of the elastic telescopic rod 58 will contact the insertion rod 57 and push the insertion rod 57 to move. The insertion rod 57 will move and disengage from the bottom of the ventilation frame 52, so that the insertion rod 57 will release the limit on the push rod 56. Under the elastic force of the first spring, the push rod 56 will move upward. When the push rod 56 moves upward, it will push the L-shaped plate 55 to rotate upward. When the L-shaped plate 55 rotates upward, it will open the top of the ventilation frame 52, so that the drive device 54 will drive the fan blade 511 to rotate. When the fan blade 511 rotates, it will discharge the gas inside the device body 1 from the ventilation frame 52.

[0038] The drive device 54 can also drive the connecting shaft 61 to rotate. When the connecting shaft 61 rotates, it will drive the arc plate 62 to rotate. When the arc plate 62 rotates, it will generate centrifugal force, causing the arc plate 62 to flip downward. When the arc plate 62 flips downward, it can prevent the gas drawn by the fan blade 511 from moving to the bottom of the partition 51, thereby improving the effect of the gas moving towards the ventilation frame 52.

[0039] When the temperature inside the device body 1 rises further, the temperature sensing device 69 will detect the temperature. As the temperature rises, the temperature sensing device 69 will increase the working power of the drive device 54, thereby increasing the rotation speed of the drive device 54 driving the fan blade 511 and the arc plate 62. When the rotation speed of the arc plate 62 increases, the downward flipping range will increase. When the arc plate 62 flips downward, it will drive the arc rod 65 to press the push switch 66, causing the push switch 66 to open the fire extinguisher 67. The extinguishing agent inside the fire extinguisher 67 will be sprayed out from inside the spray plate 68.

[0040] Rainwater can be collected through the water storage frame 71. When the L-shaped plate 55 rotates, it will push the moving plate 76 to move. When the moving plate 76 moves, it will push the filter plate 77 to rotate. When the filter plate 77 rotates, it will pull the sealing block 74 and the conveying pipe 72 through the pull rope 75, thereby releasing the seal on the conveying pipe 72 and allowing the rainwater inside the water storage frame 71 to enter the interior of the cooling plate 73. The cooling plate 73 can cool the area around the battery 53. When the moving plate 76 moves, it will collide with the protrusions 78 on the surface of the filter plate 77, causing the filter plate 77 to vibrate.

[0041] 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 alterations 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.
