Abstract
Description
Technical Field
[0001] The present application relates to the technical field of power distribution cabinet detection, and in particular to a safety performance detection device for a power distribution cabinet. Background Art
[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits, and the motor control center is used in occasions with concentrated loads and more circuits.
[0003] When the power distribution cabinet is in use, it is prone to leakage because there are multiple electrical components such as circuit breakers, contactors, relays, speed regulators and PLCs inside. Therefore, it is necessary to set up a detection device to perform leakage detection on the power distribution cabinet. For example, the Chinese patent with publication number CN114137336A in the related technology proposes a safety performance detection device for the power distribution cabinet. The device moves quickly through the conductor rod, and the first magnetic block and the second magnetic block are respectively provided on both sides of the conductor rod. The conductor rod quickly cuts the first magnetic block and the second magnetic block to generate magnetic flux lines, and the induced current generated by the conductor rod increases. The current enters the top conductor at the conductive slider, and the first resistor and the second resistor are connected in parallel in the conductor. The current can pass through the first resistor and the second resistor, and the heat dissipation detection light and the leakage detection light are turned on. The heat dissipation detection light and the leakage detection light are both on, indicating that there is leakage in the power distribution cabinet.
[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: using heat dissipation detection lights and leakage detection lights to detect whether the distribution cabinet has leakage. When the leakage detection light is on, it means that there is leakage in the distribution cabinet. When the leakage detection light does not respond, it means that the distribution cabinet can be used normally. However, this design is not convenient for waterproof protection when the distribution cabinet has leakage. As a result, if part of the distribution cabinet is flooded by rainwater on a rainy day and the distribution cabinet is leaking, the current will be guided into the rainwater along with the distribution cabinet, making it easy for maintenance personnel to get electric shock when they come to repair, and it will also affect passers-by, and the safety of the use of the distribution cabinet cannot be guaranteed. Summary of the invention
[0005] In order to solve the problem that it is inconvenient to provide waterproof protection when the distribution cabinet is leaking electricity, if part of the distribution cabinet is submerged in rainwater on a rainy day and the distribution cabinet is leaking electricity, the current will be conducted in the rainwater along the distribution cabinet body, making it easy for maintenance personnel to get electric shock when coming for maintenance, and it will also affect passers-by, the present application provides a safety performance detection device for a distribution cabinet.
[0006] The present application provides a safety performance detection device for a power distribution cabinet adopts the following technical solution:
[0007] A safety performance detection device for a power distribution cabinet, comprising a distribution box, a distributor fixed inside the distribution box, a distribution line fixed on the distributor, a plug-in strip fixed inside the distribution box, and an external wire fixed outside the plug-in strip, wherein the plug-in strip is electrically connected to the distribution line, a heat dissipation component for dissipating heat for the distributor is provided on the distribution box; a detection mechanism for detecting whether the distributor has leakage is provided on the distribution box; the detection mechanism includes a speaker component and an adjustment component; a waterproof mechanism for waterproofing the distribution box is provided on the distribution box, and the waterproof mechanism includes a water collection component and a lifting component; the adjustment component can open the water collection component, the water collection component can drive the lifting component to drive, and the lifting component can drive the distribution box to lift;
[0008] The speaker assembly includes an insulating plate arranged on the top of the distribution box, an electromagnet, a first speaker, a second speaker, a motor, a rotating disk fixed on the motor output shaft, two movable magnets fixed on the rotating disk, and a series connection member connecting the power strip, the electromagnet, the motor, the first speaker, the second speaker and the distribution box in series; when the series connection member drives the motor, the electromagnet, the first speaker and the second speaker, an alternating magnetic field can be generated between the electromagnet, the two movable magnets, the first speaker and the second speaker to drive the adjustment assembly;
[0009] The water collection assembly includes a collection frame movably arranged on the distribution box, a high-temperature nylon arranged on the top of the collection frame, a buffer for supporting the collection frame, and a fixing member for fixing the high-temperature nylon;
[0010] The lifting assembly comprises four adjusting rods fixed at the bottom of the collection frame, four adjusting plates fixed at the bottom of the distribution box, and a lifting member used for lifting and driving the four adjusting plates and the distribution box.
[0011] By adopting the above technical solution, the detection mechanism can detect whether there is leakage in the distributor. When the distributor leaks, the speaker assembly will be driven. At this time, the first speaker and the second speaker in the speaker assembly will directly make a sound, which can directly remind the staff that the distribution box has leakage and needs to be repaired. At the same time, it can remind the staff and passers-by to pay attention to safety. The traditional distribution box leakage detection method only detects leakage through the detection light. Although this detection method is effective, it is not easy to be discovered by the staff and passers-by during the day and cannot serve as a good warning. At the same time, when the distribution box leaks, it will also drive the electromagnet connected to the motor, electromagnet, The series parts on the first speaker and the second speaker will be driven to generate an alternating magnetic field to drive the adjustment component. The adjustment component can cut the high-temperature nylon on the water collection component, so that the collection frame can collect rainwater on rainy days. The weight of the rainwater can drive the lifting component to drive, and the lifting component drives the distribution box to move upward, and the height of the distribution box is adjusted to prevent the bottom of the distribution box from being submerged by rainwater. The more rainwater the collection frame collects, the higher the height of the distribution box rises due to the weight of the collection frame, which can ensure the effect of the leakage protection of the distribution box, prevent the distribution box from leaking on rainy days and affect passers-by and maintenance personnel, and ensure the safety of the use of the distribution box.
[0012] Although the prior art also has the function of lifting the distribution box to achieve the waterproof function of the distribution box, most of them drive the distribution box to lift by driving the lifting mechanism through an intelligent driver. Although this method also achieves the waterproof effect of the distribution box on rainy days, the process is too cumbersome. On rainy days, it is necessary to start the intelligent driver to drive the distribution box to lift, and it also consumes a lot of costs to drive through multiple intelligent drivers. In addition, although a water collecting mechanism is also provided on the top of the distribution box in the prior art to achieve the waterproof effect and lifting effect on the top of the distribution box, this method can also achieve the waterproof effect on the top of the distribution box, but this method requires regular cleaning of the water collecting mechanism, because it is usually light rain on rainy days. Too frequent long-term water accumulation and outdoor use will be stained with a lot of dust and stains, and the use process is too complicated. In addition, when the distribution box is in normal use, it does not need to be lifted on light rainy days, because light rainy days will not flood the distribution box. If the distribution box is lifted on rainy days, it will cause a lot of troubles to the staff. The use scenario of this design is very special. Rainwater will only be collected in heavy rain and when the distribution box leaks electricity. The distribution box will be raised and lowered to make it waterproof. First, high-temperature nylon is set on the top of the collection frame to make the top of the collection frame and the distribution box waterproof and high-temperature resistant. On light rainy days, rainwater can be prevented from entering the inner side of the collection frame, and rainwater can flow directly down along the high-temperature nylon. At the same time, stains and impurities can be prevented from entering the inner side of the collection frame. At the same time, the collection frame can be prevented from rising and falling on light rainy days. If the distribution box leaks electricity, it will first drive the adjustment component to directly pierce the high-temperature nylon and open the collection frame. Therefore, the collection frame can collect rainwater on rainy days and can be directly passed through As the weight of rainwater in the collection frame gradually increases, the weight of the rainwater and the buffering force of the four buffer springs drive the four adjustment rods to move downward, and then drive the lifting assembly to drive the distribution box to move upward, thereby ensuring the stability of the distribution box in upward movement, and preventing the distribution box from conducting current in the rainwater and causing harm to passers-by and staff when there is a leakage. Moreover, the design can directly drive the distribution box to rise and fall when there is a leakage, and there is no need to set up an additional intelligent drive to lift the distribution box, and there is no need for staff to drive the intelligent drive on rainy days, so as to reduce the cost of making the distribution box.
[0013] Optionally, the series component includes a support block fixed on the top of the insulating plate, the top of the support block is fixedly connected to the motor, the two active magnets and the electromagnet are located between the first speaker and the second speaker, the two active magnets are located directly above the electromagnet, a cathode wire and an anode wire are provided on the outside of the motor, the cathode wire is welded to the outer surface of the first speaker, and the anode wire is welded to the outer surface of the second speaker, the two active magnets are magnetically connected to the first speaker and the second speaker without contact, the two active magnets, the first speaker and the second speaker are magnetically connected to the electromagnet without contact, and the first speaker and the second speaker are both composed of structures such as magnetic steel, coil, iron frame and voice coil.
[0014] By adopting the above technical solution, when the electromagnet is driven, the rotating disk and the two movable magnets on the motor can be driven to rotate. Because the anode wire of the motor is welded to the second speaker, and the cathode wire is welded to the first speaker, the first speaker and the second speaker are both composed of structures such as magnetic steel, coils, iron frames and voice coils, which can play the role of an electromagnetic coil. Therefore, when the electromagnet generates magnetic force, the magnetic force is added between the first speaker, the second speaker and the two movable magnets, so that the magnetic field magnetic force between the first speaker, the second speaker and the two movable magnets is no longer balanced and symmetrical, so that the motor will be subjected to a torque, and the torque will drive the motor to drive the rotating disk and the two movable magnets to rotate, so that the motor and the second speaker and the first speaker can generate a current conductor. The reason for the rotation of the motor is the interaction between the magnetic field generated by the current passing through the first speaker, the second speaker, the anode wire and the cathode wire and the two movable magnets and the electromagnet. This interaction force is expressed in the form of magnetic torque to drive the motor to rotate continuously, which can drive the two movable magnets to rotate continuously. Therefore, the adjustment component can be driven by the two movable magnets to facilitate the adjustment component to open the water collection component.
[0015] Optionally, a positive wire and a negative wire are provided on the outside of the electromagnet, the positive wire is connected to the positive pole of the second speaker, the negative wire is connected to the negative pole of the first speaker, a neutral wire is provided on the outside of the second speaker, the neutral wire is connected to the zero terminal connector in the power strip, the neutral wire is connected to the negative pole of the second speaker, and a live wire is provided on the outside of the first speaker, the live wire is connected to the inner top wall of the distribution box.
[0016] By adopting the above technical scheme, when the distributor leaks electricity, the current of the distributor will be guided to the distribution box, and the current will flow to the live wire, the first speaker, the electromagnet, the positive wire, the second speaker and the neutral wire in sequence. Because the neutral wire is connected to the zero-end connector of the power strip, when the distributor leaks electricity, a series circuit can be formed between the power strip, the distribution box, the live wire, the first speaker, the electromagnet, the positive wire, the second speaker and the neutral wire, which can drive the first speaker, the electromagnet and the second speaker to make a sound to remind the staff that the distribution box has a leakage and needs to be repaired, and can also remind the staff and passers-by to pay attention to safety. When the distributor does not leak electricity, the distribution box will not generate current, so the live wire will not introduce current, so a series circuit cannot be formed between the power strip, the distribution box, the live wire, the first speaker, the electromagnet, the positive wire, the second speaker and the neutral wire, so the first speaker, the electromagnet and the second speaker will not be driven, indicating that the distribution box is safe at this time and can be used normally.
[0017] Optionally, the adjustment component includes a lifting rod movably arranged on the collection frame, the bottom end of the lifting rod is hinged with a movable seesaw, a sharp knife is arranged on the top of the lifting rod, the two movable magnets are movably fitted with the movable seesaw, the high-temperature nylon is movably fitted with the sharp knife, the sharp knife is located on the inner side of the collection frame, a supporting seesaw is arranged on the top of the insulating plate, the supporting seesaw is hinged with the movable seesaw, a water collecting cylinder is arranged on the top of the supporting seesaw, a water outlet is opened on the inner side of the water collecting cylinder, the water collecting cylinder is located on the outer side of the collection frame, the combined weight of the lifting rod and the sharp knife is greater than the weight of the water collecting cylinder, and when the inner side of the water collecting cylinder is full of water, the weight of the water collecting cylinder is greater than the combined weight of the lifting rod and the sharp knife.
[0018] By adopting the above technical solution, when the distribution box encounters light rain weather without leakage, the water collecting cylinder can collect rainwater. Because the water collecting cylinder is provided with a water outlet hole, rainwater can also flow out from the water outlet hole, and the water collecting cylinder will not be filled with water. At the same time, the water collecting cylinder will not drive the lifting rod and the sharp knife to move up and cut the high-temperature nylon, so as to save the frequency of replacing the high-temperature nylon, because in light rain weather, rainwater will not flood the distribution box and cause leakage accidents;
[0019] When the distribution box has no leakage and encounters heavy rain, rainwater will quickly collect in the water collection barrel, and the water outlet cannot quickly discharge the rainwater. When the inner side of the water collection barrel is full of water, the weight of the water collection barrel will be greater than the weight of the lifting rod and the sharp knife. Through the hinged cooperation between the supporting seesaw and the lifting rod, the lifting rod and the sharp knife can be driven to move upward to cut the high-temperature nylon, so that rainwater can be collected through the collection frame, and then the weight of the rainwater collected by the collection frame can drive the lifting assembly to drive the distribution box to move upward, which can avoid the distribution box from being submerged due to excessive rainwater, prevent rainwater from entering the inner side of the distribution box to cause current interference and cause leakage, and ensure the safety of the leakage protection of the distribution box;
[0020] When the two movable magnets rotate, they will drive the movable seesaw, the lifting rod and the sharp knife to move up and down in turn. When the sharp knife moves up and down, it can pierce the high-temperature nylon, so that the high-temperature nylon will split instantly, and the collection frame can be opened. Therefore, when the distribution box leaks electricity, the high-temperature nylon will be directly cut off. In this way, no matter it is light rain or heavy rain, the collection frame will collect rainwater and drive the lifting assembly to drive the distribution box to move upward away from the ground, so as to prepare leakage protection in advance for rain and reduce the chance of electric shock to passers-by.
[0021] Optionally, the buffer component includes fixed blocks fixed on the left and right sides of the distribution box, the number of the fixed blocks is four, buffer springs are arranged on the inner sides of the four fixed blocks, buffer rods are arranged on the tops of the four buffer springs, and the four buffer rods are fixedly connected to the collection frame.
[0022] By adopting the above technical solution, when the collecting frame collects rainwater, as the rainwater accumulates more and more, the collecting frame will become heavier, and the four buffer springs will be in a compressed state. Through the cooperation of the four fixed blocks, the four buffer springs and the four buffer rods, the collecting frame can be buffered and supported, so that the collecting frame moves downward slowly due to its weight, thereby preventing the collecting frame from directly driving the lifting assembly due to its weight, thereby interfering with the normal use of the distribution box.
[0023] Optionally, the lifting member includes four drive boxes arranged at the bottom of the distribution box, the inner sides of the four drive boxes are movably connected with threaded rods, the outer sides of the four threaded rods are threadedly connected with threaded blocks, the four threaded blocks are respectively fixedly connected to four adjustment plates, the outer sides of the four threaded rods are provided with first bevel gears, the outer sides of the four first bevel gears are meshed with second bevel gears, the inner sides of the four second bevel gears are provided with support rods, the outer sides of the four support rods are provided with movable gears, the outer sides of the four movable gears are meshed with movable racks, and the four movable racks are respectively fixedly connected to four adjustment rods.
[0024] By adopting the above technical solution, when the collecting frame moves downward due to rainwater, it will drive the four adjusting rods and the four movable racks to move downward respectively, and then drive the four movable gears, four supporting rods, four second bevel gears, four first bevel gears and four threaded rods to rotate respectively, thereby driving the four threaded blocks, four adjusting plates and the distribution box to move upward respectively, so that the height of the distribution box can be adjusted to prevent the bottom of the distribution box from being submerged due to rainwater, and the effect of the leakage protection of the distribution box can be ensured, so as to prevent the distribution box from leaking on rainy days and affecting passers-by and maintenance personnel, thereby ensuring the safety of the use of the distribution box.
[0025] Optionally, the heat dissipation assembly includes a heat dissipation box fixed to the bottom of a distribution box, a heat sink is arranged on the inner side of the heat dissipation box, a partition plate is arranged on the inner side of the heat dissipation box, an air intake pipe is arranged on the top of the heat dissipation box, the top of the air intake pipe passes through the heat dissipation box and the distribution box in sequence and extends to the inner side of the distribution box, the heat sink is composed of an electric motor, a motor shaft, fan blades, a support plate and rolling bearings, and two heat dissipation pipes are arranged on the top of the distribution box.
[0026] By adopting the above technical solution, the heat sink is driven to blow wind into the inside of the distribution box through the heat sink and the air intake pipe in turn. The wind circulates and drifts inside the distribution box to dissipate heat for the distributor, thus preventing the distributor from burning out due to over-high temperature. In combination with the two heat pipes, the inside of the distribution box can be ventilated to ensure the heat dissipation effect of the distributor.
[0027] Optionally, an adjustment block is provided on the inner side of the heat sink, a movable plate is provided on the bottom of the adjustment block, a movable plate is provided on the bottom of the movable plate, a movable rod is movably connected to the inner side of the heat sink, a limiting block is provided on the left end of the movable rod, a movable cone plate is provided on the right end of the movable rod, an air adjusting plate is provided on the bottom of the movable cone plate, an annular spring is provided on the left side of the movable cone plate, a scale is provided on the left side of the heat sink, the annular spring is fixedly connected to the heat sink, the movable cone plate is a three-vertebral body, the movable plate and the inclined surface of the movable cone plate are movably fitted together, an adjustment square hole is provided on the right side of the partition plate, the air adjusting plate is slidably connected to the adjustment square hole, the air adjusting plate is located above the heat sink, and the adjustment block is fitted with the distributor.
[0028] By adopting the above technical solution, because the adjustment block is fitted with the distributor, when the temperature of the distributor rises, the adjustment block will expand due to the high temperature, and when the temperature of the distributor decreases, the adjustment block will shrink due to the low temperature, so the adjustment block will change with the temperature of the distributor, and when the adjustment block expands or shrinks, it will drive the movable plate and the moving plate to move up and down in turn. The annular spring can make the movable rod, the movable cone plate and the air regulating plate have a buffering effect, so when the movable plate moves up and down, it can drive the movable cone plate, the air regulating plate, the movable rod and the limit block to move left and right in turn, and the size of the wind gap between the air regulating plate and the heat dissipation box can be controlled to control the wind force entering the inside of the distribution box. When the temperature of the distributor is high, the air regulating plate can be driven to move to the left to increase the wind gap between the air regulating plate and the heat dissipation box. When the temperature of the distributor is low, the air regulating plate can be driven to move to the right to decrease the wind gap between the air regulating plate and the heat dissipation box, so that the distributor can dissipate heat at the optimal temperature to avoid the phenomenon that the distributor becomes wet due to the low temperature. Controlling the distributor to dissipate heat at the optimal temperature can minimize damage to the distributor.
[0029] Optionally, the fixing device includes screw racks fixed on the left and right sides of the collection frame, and the number of the screw racks is six. The inner sides of the six screw racks are threadedly connected with screw rods, the outer sides of the six screw rods are provided with movable pressure blocks, the outer sides of the six movable pressure blocks are provided with movable turning handles, and the six movable pressure blocks are movably connected to high-temperature nylon.
[0030] By adopting the above technical solution, when the high-temperature nylon on the collecting frame needs to be disassembled and replaced, the six movable handles can be rotated to drive the six spiral rods and the six movable pressure blocks to rotate and move left and right respectively, so that the six movable pressure blocks can be separated from the high-temperature nylon, and the high-temperature nylon can be disassembled and replaced. At the same time, through the cooperation of the six screw frames, six spiral rods, six movable pressure blocks and six movable handles, the high-temperature nylon can be stably installed on the collecting frame to avoid the high-temperature nylon from falling off, and the top of the collecting frame can have a waterproof effect.
[0031] Optionally, a floating plate is provided at the bottom of the heat sink, and floating balls are provided at the top of the floating plate, and the floating balls are evenly distributed on the top of the floating plate; an inflation tube is provided at the outside of the heat sink, and a solenoid valve is fixedly installed at the outside of the inflation tube; an electric valve switch is provided at the bottom of the collection frame, and a trigger block is provided at the outside of the lifting rod, and the trigger block is movably fitted with the electric valve switch; the inlet and outlet of the inflation tube are respectively connected with the floating plate and the heat sink; an air storage cavity is provided on the inner side of the floating plate, and a plurality of the floating balls are connected with the air storage cavity; the inflation tube is located on the inner side of the air storage cavity, and the solenoid valve is electrically connected with the electric valve switch.
[0032] By adopting the above technical scheme, when the distribution cabinet leaks electricity or encounters heavy rain, the lifting rod will also drive the trigger block to move upward when moving upward and fit with the electric valve switch to open the solenoid valve. When the heat sink blows air to dissipate heat to the distribution cabinet, the wind will enter the air storage cavity through the inflation tube, and the wind will enter the multiple floating balls in turn. The multiple floating balls are inflated to ensure the buoyancy of the floating plate and the multiple floating balls on the heat dissipation box and the distribution box. When encountering heavy rain, rainwater cooperates with the floating plate and the multiple floating balls to cooperate with the water collection assembly and the lifting assembly to drive the distribution box to move upward, which can avoid the distribution box being insufficient for the lifting assembly to drive the distribution box to lift due to the influence of weight, and can also prevent the distribution box from being submerged by rainwater in heavy rain or leakage.
[0033] In summary, the present application includes at least one of the following beneficial technical effects:
[0034] 1. When encountering light rain, the water collection tube can collect rainwater. Because there is a water outlet on the water collection tube, rainwater can also flow out from the water outlet, and the water collection tube will not be filled with water. At the same time, the water collection tube will not drive the lifting rod and the sharp knife to move up and cut the high-temperature nylon to save the frequency of replacing the high-temperature nylon. Because in light rain, rainwater will not flood the distribution box and cause leakage accidents. When encountering heavy rain, rainwater will quickly collect in the water collection tube, and the water outlet cannot quickly discharge the rainwater. When the inner side of the water collection tube When the water is full, the weight of the water collection cylinder will be greater than the weight of the lifting rod and the sharp knife. Through the hinged cooperation between the supporting seesaw and the lifting rod, the lifting rod and the sharp knife can be driven to move upward to cut the high-temperature nylon, so that rainwater can be collected through the collection frame. Then, the weight of the rainwater collected by the collection frame can drive the lifting assembly to drive the distribution box to move upward, which can prevent the distribution box from being submerged due to excessive rainwater, and prevent rainwater from entering the inner side of the distribution box to cause current interference and cause leakage, thereby ensuring the safety of the leakage protection of the distribution box;
[0035] 2. When the distributor leaks electricity, the current will be directed to the distribution box, and then the current will flow to the live wire, the first speaker, the electromagnet, the positive wire, the second speaker and the neutral wire in sequence. Because the neutral wire is connected to the zero-end connector of the power strip, when the distributor leaks electricity, a series circuit can be formed between the power strip, the distribution box, the live wire, the first speaker, the electromagnet, the positive wire, the second speaker and the neutral wire, which can drive the first speaker, the electromagnet and the second speaker, and make a sound when the first speaker and the second speaker are driven, reminding the staff that the distribution box needs to be repaired due to leakage, and at the same time reminding the staff and passers-by to pay attention to safety;
[0036] 3. When the electromagnet is driven, it can drive the rotating disk and two movable magnets on the motor to rotate. When the electromagnet generates magnetic force, the magnetic force is added between the first speaker, the second speaker and the two movable magnets, so that the motor will be subjected to a torque. The torque will drive the motor to drive the rotating disk and the two movable magnets to rotate, and the motor, the second speaker and the first speaker can generate a current conductor. The reason for the rotation of the motor is the interaction between the magnetic field generated by the current passing through the first speaker, the second speaker, the anode wire and the cathode wire and the two movable magnets and the electromagnet. This interaction force is expressed in the form of magnetic torque to drive the motor to rotate continuously, and can drive the two movable magnets to rotate continuously. When the two movable magnets rotate, they will drive the movable seesaw, the lifting rod and the sharp knife to move up and down in turn to pierce the high-temperature nylon, and the high-temperature nylon will split. Therefore, when the distribution box leaks electricity and it rains, the collection frame can collect rainwater. As the rainwater accumulates more The more collecting frames there are, the heavier they will be. Through the cooperation of four fixed blocks, four buffer springs and four buffer rods, the collecting frame moves slowly downward due to the weight. When the collecting frame moves downward due to rain, through the cooperation of four adjusting rods, four movable racks, four movable gears, four supporting rods, four second bevel gears, four first bevel gears, four threaded rods, four threaded blocks and four adjusting plates, the distribution box can be driven to move upward to prevent the bottom of the distribution box from being submerged by rain. The heavier the weight of the collecting frame, the higher the height of the distribution box can be raised, which can ensure the effect of leakage protection of the distribution box, prevent the distribution box from affecting passers-by and maintenance personnel due to leakage on rainy days, and ensure the safety of the use of the distribution box. When the distribution cabinet leaks electricity, whether it is light rain or heavy rain, the collecting frame will collect rainwater, drive the lifting assembly to drive the distribution box to move upward away from the ground, prepare leakage protection for rain in advance, and reduce the probability of electric shock to passers-by.
[0037] 4. The heat sink blows the wind into the distribution box through the heat sink and the air inlet pipe in turn, which can dissipate the heat of the distributor. With the two heat sinks, the distribution box can have a ventilation effect to ensure the heat dissipation effect of the distributor. When the temperature of the distributor rises, the adjustment block will expand due to the high temperature. When the temperature of the distributor decreases, the adjustment block will shrink due to the low temperature. When the adjustment block expands or shrinks, the wind distance between the air adjustment plate and the heat sink can be controlled through the cooperation between the movable plate, the moving plate, the annular spring, the movable rod, the movable cone plate, the air adjustment plate and the limit block. The size of the gap is used to control the wind force entering the inside of the distribution box. The larger the wind gap between the air regulating plate and the heat dissipation box, the faster the wind force enters the distribution box and the faster the heat dissipation of the distributor. The smaller the wind gap between the air regulating plate and the heat dissipation box, the slower the wind force enters the distribution box, so that the distributor can dissipate heat at the best temperature and avoid moisture in the distributor due to low temperature. Controlling the distributor to dissipate heat at the best temperature can avoid the distributor from aging faster due to high temperature and reduce the probability of leakage.
[0038] 5. When the distribution cabinet leaks electricity or encounters heavy rain, the lifting rod will move upward and drive the trigger block to move upward, which can fit with the electric valve switch to open the solenoid valve. Then, when the heat sink is blowing and cooling the distributor, the wind will enter the inner side of the air storage cavity through the inflation tube, so that the wind will enter the inner side of multiple floating balls in turn. Multiple floating balls can be inflated to generate buoyancy, which can ensure the buoyancy of the floating board and multiple floating balls on the heat dissipation box and the distribution box. In heavy rain, rainwater can cooperate with the floating board and multiple floating balls to The combined water collection component and the lifting component drive the distribution box to move upward, while the floating plate and multiple floating balls can ensure the stability and speed of the distribution box's upward movement, and at the same time prevent the distribution box from being insufficiently lifted by the lifting component due to the influence of weight, thereby preventing the distribution box from being submerged by rainwater in heavy rain or when there is a leakage. By arranging air holes on the top of the floating plate, the floating plate can be made breathable, thereby preventing the multiple floating balls from rupturing due to excessive gas when the floating plate is inflated, thereby ensuring the use effect of the multiple floating balls.

If the heat sink 43 leaks, it can play an insulating protection role.Avoid leakage of heat sink 43 into rainwater.
[0062] The implementation principle of a safety performance detection device for a power distribution cabinet in the embodiment of the present application is as follows:
[0063] (1) When encountering light rain weather, the water collecting tube 69 can collect rainwater. Because the water collecting tube 69 is provided with a water outlet, rainwater can also flow out from the water outlet, and the water collecting tube 69 will not be filled with water. At the same time, the water collecting tube 69 will not drive the lifting rod 25 and the sharp knife 26 to move up and cut the high-temperature nylon 31, so as to save the frequency of replacing the high-temperature nylon 31, because in light rain weather, rainwater will not flood the distribution box 1 and cause leakage accidents;
[0064] (2) When it rains heavily, rainwater will quickly collect in the water collection tube 69, and the water outlet cannot quickly drain the rainwater. When the inner side of the water collection tube 69 is full of water, the weight of the water collection tube 69 will be greater than the weight of the lifting rod 25 and the sharp knife 26. The hinged cooperation between the supporting seesaw 68 and the lifting rod 25 can drive the lifting rod 25 and the sharp knife 26 to move upward, cut the high-temperature nylon 31, and collect rainwater through the collection frame 30. The weight of the rainwater collected by the collection frame 30 can drive the lifting assembly to drive the distribution box 1 to move upward, which can prevent the distribution box 1 from being submerged due to excessive rainwater, and prevent rainwater from entering the inner side of the distribution box 1 to cause current interference and cause leakage, thereby ensuring the safety of the leakage protection of the distribution box 1;
[0065] (3) When the distributor 2 leaks electricity, the current of the distributor 2 will be directed to the distribution box 1, and then the current will flow to the live wire 22, the first speaker 12, the electromagnet 7, the positive wire 21, the second speaker 13 and the neutral wire 20 in sequence. Because the neutral wire 20 is connected to the zero-end connector of the power strip 4, when the distributor 2 leaks electricity, a series circuit can be formed between the power strip 4, the distribution box 1, the live wire 22, the first speaker 12, the electromagnet 7, the positive wire 21, the second speaker 13 and the neutral wire 20, thereby driving the first speaker 12, the electromagnet 7 and the second speaker 13. When the first speaker 12 and the second speaker 13 are driven, a sound can be emitted, thereby reminding the staff that the distribution box 1 has a leakage and needs to be repaired, and at the same time reminding the staff and passers-by to pay attention to safety;
[0066] (4) Because the two movable magnets 11 and the electromagnet 7 are located between the first speaker 12 and the second speaker 13, and the two movable magnets 11 are located directly above the electromagnet 7, the two movable magnets 11 and the first speaker 12 and the second speaker 13 are all in non-contact magnetic connection, and the two movable magnets 11, the first speaker 12 and the second speaker 13 are all in non-contact magnetic connection with the electromagnet 7, so when the electromagnet 7 is driven, it can drive the rotating disk 10 on the motor 9 and the two movable magnets 11 to rotate. Because the anode wire 19 of the motor 9 is welded to the second speaker 13, and the cathode wire 18 is welded to the first speaker 12, the first speaker 12 and the second speaker 13 are both composed of a magnetic steel, a coil, an iron frame and a voice coil, and can play the role of an electromagnetic coil, so the electromagnet 7 generates When magnetic force is applied, magnetic force is added between the first speaker 12, the second speaker 13 and the two movable magnets 11, so that the magnetic field magnetic force between the first speaker 12, the second speaker 13 and the two movable magnets 11 is no longer balanced and symmetrical, so that a torque is applied to the motor 9, and the torque drives the motor 9 to drive the rotating disk 10 and the two movable magnets 11 to rotate, so that the motor 9, the second speaker 13 and the first speaker 12 can generate a current conductor. The reason why the motor 9 rotates is the interaction between the magnetic field generated by the current passing through the first speaker 12, the second speaker 13, the anode wire 19 and the cathode wire 18 and the two movable magnets 11 and the electromagnet 7. This interaction force is manifested in the form of magnetic torque to drive the motor 9 to rotate continuously, and then drive the two movable magnets 11 to rotate continuously;
[0067] (5) When the two movable magnets 11 rotate, they will drive the movable seesaw 24, the lifting rod 25 and the sharp knife 26 to move up and down in turn. When the sharp knife 26 moves up and down, it can pierce the high-temperature nylon 31, so that the high-temperature nylon 31 will split instantly. Therefore, when the distribution box 1 leaks electricity and encounters rainy days, the collection frame 30 can collect rainwater. As the rainwater accumulates more and more, the collection frame 30 will become heavier and heavier, and the four buffer springs 28 will be in a compressed state. Then, through the cooperation between the four fixed blocks 27, the four buffer springs 28 and the four buffer rods 29, the collection frame 30 can be buffered and supported, so that the collection frame 30 moves slowly downward due to its weight;
[0068] (6) When the collection frame 30 moves downward due to its weight, it will drive the four adjustment rods 41 and the four movable racks 40 to move downward respectively. Because the four movable racks 40 are respectively engaged with the four movable gears 39, the four movable racks 40 will respectively drive the four movable gears 39, the four support rods 38 and the four second bevel gears 37 to rotate when they move downward. Because the four second bevel gears 37 are respectively engaged with the four first bevel gears 36, when the four second bevel gears 37 rotate, they will respectively drive the four first bevel gears 36 and the four threaded rods 33 to rotate. Because the four threaded rods 33 are respectively threadedly connected to the four threaded blocks 34, when the four threaded rods 33 rotate, they will respectively drive the four The threaded block 34 and the four adjustment plates 35 move upward, and when the four adjustment plates 35 move upward, the distribution box 1 can be driven to move upward, and the height of the distribution box 1 can be adjusted to prevent the bottom of the distribution box 1 from being submerged by rainwater. The heavier the weight of the collection frame 30, the higher the height of the distribution box 1 can be raised, which can ensure the effect of leakage protection of the distribution box 1, and prevent the distribution box 1 from affecting passers-by and maintenance personnel due to leakage on rainy days, thereby ensuring the safety of the use of the distribution box 1. When the distribution box 1 leaks electricity, whether it is light rain or heavy rain, the collection frame 30 will collect rainwater, drive the lifting assembly to drive the distribution box 1 to move upward away from the ground, prepare leakage protection for rain in advance, and reduce the probability of electric shock to passers-by;
[0069] (7) The heat sink 43 is driven to blow wind into the inner side of the distribution box 1 through the heat sink 42 and the air inlet pipe 45 in sequence. The wind circulates and drifts inside the distribution box 1 to dissipate heat for the distributor 2, thereby preventing the distributor 2 from burning out due to excessive temperature. In combination with the two heat sinks 57, the inner side of the distribution box 1 can be ventilated to ensure the heat dissipation effect of the distributor 2.
[0070] (8) Because the regulating block 46 fits with the distributor 2, when the temperature of the distributor 2 rises, the regulating block 46 will expand due to the high temperature, and when the temperature of the distributor 2 drops, the regulating block 46 will shrink due to the low temperature. Therefore, the regulating block 46 will change with the temperature of the distributor 2. When the regulating block 46 expands or shrinks, it will drive the movable plate 47 and the movable plate 48 to move up and down in turn. Because the movable plate 48 fits with the inclined surface of the movable cone plate 51, the annular spring 53 can make the movable rod 49, the movable cone plate 51 and the air regulating plate 52 have a buffering effect. Therefore, when the movable plate 48 moves up and down, it can drive the movable cone plate 51, the air regulating plate 52, the movable rod 49 and the limit block 50 to move left and right in turn. When the air regulating plate 52 moves left and right, the size of the wind gap between the air regulating plate 52 and the heat dissipation box 42 can be controlled to control the wind force entering the inner side of the distribution box 1. When the temperature of the distributor 2 is high, the regulating block 46 will expand, which can drive the air regulating plate 5 2 moves to the left, so that the wind gap between the air regulating plate 52 and the heat dissipation box 42 becomes larger, so as to increase the flow rate of wind entering the distribution box 1 and strengthen the heat dissipation speed of the distributor 2. When the temperature of the distributor 2 is low, the regulating block 46 will shrink, which can drive the air regulating plate 52 to move to the right, so that the wind gap between the air regulating plate 52 and the heat dissipation box 42 becomes smaller, so as to reduce the flow rate of wind entering the distribution box 1, so that the distributor 2 can dissipate heat at an optimal temperature, and avoid the phenomenon of moisture in the distributor 2 due to low temperature. Controlling the distributor 2 to dissipate heat at an optimal temperature can minimize damage to the distributor 2 and prevent the distributor 2 from burning out due to high temperature. At the same time, it can avoid the distributor 2 from accelerating the aging speed due to excessively high temperature, and increase the service life of the distributor 2 to reduce the probability of leakage of the distributor 2. At the same time, when the limit block 50 moves left and right, the current position of the limit block 50 can be detected by the scale 54 to detect the current temperature change of the distributor 2;
[0071] (9) When the high-temperature nylon 31 on the collection frame 30 needs to be disassembled and replaced, the six movable handles 64 can be rotated to drive the six screw rods 62 and the six movable pressing blocks 63 to rotate respectively. Because the six screw racks 61 are respectively threadedly connected to the six screw rods 62, the six screw rods 62 rotate to drive the six movable pressing blocks 63 to rotate left and right, so that the six movable pressing blocks 63 can be separated from the high-temperature nylon 31, so that the high-temperature nylon 31 loses its limit, so that the high-temperature nylon 31 can be disassembled and replaced;
[0072] (10) At the same time, through the cooperation between the six screw racks 61, the six screw rods 62, the six movable pressing blocks 63 and the six movable turning handles 64, the high-temperature nylon 31 can be stably installed on the collection frame 30 to prevent the high-temperature nylon 31 from falling off, so that the top of the collection frame 30 has a waterproof effect;
[0073] (11) Therefore, according to the above principle, when the distributor 2 leaks electricity and it is raining, a series circuit will be formed between the power strip 4, the distribution box 1, the live wire 22, the first speaker 12, the electromagnet 7, the positive wire 21, the second speaker 13 and the neutral wire 20, driving the first speaker 12, the electromagnet 7 and the second speaker 13. When the first speaker 12 and the second speaker 13 are driven, a prompt sound will be generated, thereby reminding the staff to come and deal with it, and reminding the staff and passers-by to pay attention to safety. At the same time, when the electromagnet 7 is driven, it cooperates with the motor 9, the electromagnet 7, the first speaker 12, the second speaker 13 and the series connection to generate an alternating magnetic field, which can drive the two movable magnets 11 to rotate continuously, thereby pushing the movable seesaw 24, the lifting rod 25 and the sharp knife 26 to cut the high-temperature nylon 31, so that the collection frame 30 can collect rainwater on rainy days. The distribution box 1 can be moved upward by the weight of rainwater to avoid the bottom of the distribution box 1 being submerged by rainwater, thereby ensuring the safety of the distribution box 1. This method can be used to prevent accidents. On rainy days, the distribution box 1 can achieve a good leakage protection effect. After the staff has repaired the distribution box 1, they can disassemble the cut high-temperature nylon 31 and take out the new high-temperature nylon 31 from the storage box 55. The rainwater inside the collection frame 30 can be released and the top of the distribution box 1 can be covered with the high-temperature nylon 31 for waterproofing, so as to re-protect the distribution box 1 from leakage. The high-temperature nylon 31 can be used to cover the top of the collection frame 30 to achieve a good waterproof effect and prevent the high-temperature nylon 31 from being damaged by high temperature and easily cut by the sharp knife 26. In addition, the high-temperature nylon 31 is cheap and does not cost a lot.
[0074] (12) When the distribution cabinet leaks electricity or encounters heavy rain, the lifting rod 25 will also drive the trigger block 73 to move upward when it moves upward, and can fit with the electric valve switch 72 to open the solenoid valve 71. Then, when the heat sink 43 blows air to dissipate heat to the distributor 2, the wind will also enter the inner side of the air storage cavity through the inflation tube 70, so that the wind will enter the inner side of the multiple floating balls 67 in turn, and the multiple floating balls 67 can be inflated to generate buoyancy, which can ensure the buoyancy of the floating plate 66 and the multiple floating balls 67 on the heat sink 42 and the distribution box 1. When encountering heavy rain, the rainwater cooperates with the floating plate 66 and the multiple floating balls 67, and the rainwater collected in the collection frame 30 will gradually drive the four adjustment rods 41 to move downward due to the weight, through the four fixed blocks 27, the four buffer springs 28, the four buffer rods 29, the four adjustment rods 41, and the four The cooperation among the movable rack 40, four movable gears 39, four support rods 38, four second bevel gears 37, four first bevel gears 36, four drive boxes 32, four threaded rods 33, four threaded blocks 34 and four adjustment plates 35 can gradually drive the distribution box 1 to move upward. At the same time, the floating plate 66 and multiple floating balls 67 can ensure the stability and speed of the distribution box 1 moving upward, and at the same time, it can avoid the distribution box 1 being insufficient for the lifting assembly to drive the distribution box 1 to move up and down due to the influence of weight, and prevent the distribution box 1 from being submerged by rainwater in heavy rain or leakage. By arranging air holes on the top of the floating plate 66, the floating plate 66 can have a breathable effect, and avoid the phenomenon that the multiple floating balls 67 are ruptured due to excessive gas when the floating plate 66 is inflated, so as to ensure the use effect of the multiple floating balls 67.
[0075] Compared with the prior art, this design does not require any intelligent driver to be set up for driving, because if the distribution box 1 is still driven to rise and fall by the intelligent driver when there is a leakage in the distribution box 1, a series of serious effects will occur. First, if the leakage current is conducted to the intelligent driver, it will cause local overheating of the intelligent driver, which may cause a fire. At the same time, it will also aggravate the risk of leakage in the distribution box 1, forming a vicious circle, further threatening the safety of passers-by and property. In addition, when the distribution box 1 is driven to rise and fall by multiple intelligent drivers, leakage will lead to an increase in power consumption, resulting in energy waste and increasing The electricity cost, and the leakage detection mechanism, sound speaker component, water collection component and lifting component set up can be automatically driven according to the leakage of the distribution box 1 and heavy rain weather, and there is no need to add additional intelligent drivers, so these problems can be avoided. The distribution box 1 can be automatically lifted and lowered by rainwater to achieve rain protection of the distribution box 1 and avoid the distribution box 1 being flooded by rainwater. At the same time, the leakage protection of the distribution box 1 can be achieved, and the consumption of energy can be reduced to prevent the leakage phenomenon from further deteriorating, and avoid the leakage intelligent driver of the distribution box 1 causing additional damage to the distributor 2 in the distribution box 1.
[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
