Description

Technical Field

[0001] This invention relates to the field of electrical distribution box line testing technology, specifically to a electrical distribution box line testing device. Background Technology

[0002] Electrical distribution box line inspection is a crucial step in ensuring electrical safety, involving aspects such as leakage current detection, line aging inspection, and grounding system assessment. Line inspection devices are typically installed inside the distribution box to periodically monitor the line transmission conditions, thereby improving electrical safety. For example, a distribution box line inspection device with announcement number CN116449140B, belonging to the field of electrical line inspection technology, includes an outer casing containing a detection component. Mounting components are located on both sides of the detection component. The detection component includes an outer cover, with an inner fixing cover fixedly connected inside the outer cover. The outer cover has multiple jet pipes that are fixedly connected through it, and the inner fixed cover has multiple exhaust ports that are connected to the jet pipes. The inner fixed cover has an inner rotating cover, and the outer side of the inner rotating cover has multiple rotating rods fixedly installed. The end of the rotating rod away from the inner rotating cover is fixedly equipped with a sealing block, which is slidably connected to the inner wall of the inner fixed cover. By setting a detection component, it can automatically extinguish fires when a fault occurs in the circuit inside the distribution box and spontaneous combustion occurs. It can also send a warning signal in real time. It has the ability to automatically detect power faults in the distribution box, which makes it convenient for power maintenance personnel to accurately locate the faulty distribution box. It has good performance.

[0003] For example, a distribution box circuit testing device with announcement number CN118243974B relates to the field of electrical circuit testing technology. This distribution box circuit testing device includes a cabinet and external wiring, as well as a clamping device. The clamping device includes a wiring frame, a wiring plate, a receiving rod, a U-shaped rod, a clamping plate, a receiving plate, a fixing rod, a crossbar, and a triangular plate. The wiring frame is fixedly installed through the inner and outer walls of the cabinet. The wiring plate is slidably installed inside the wiring frame. The receiving rod slidably penetrates the left and right walls of the wiring plate. The U-shaped rod slidably penetrates the inner and outer walls of the wiring frame. The clamping plate is slidably installed on the side of the wiring plate. The receiving plate is fixedly installed above the clamping plate. This distribution box circuit testing device enables rapid installation and removal of external wiring, facilitating testing by personnel. It also ensures tight contact between the external wiring and the wiring plate, reducing testing errors and improving the testing efficiency of the distribution box. However, the above-mentioned distribution box circuit testing device still has the following drawbacks in actual use:

[0004] 1. Traditional distribution boxes mostly do not have circuit detection devices installed inside. The circuits inside the distribution box are usually inspected periodically by construction personnel, so it is impossible to detect circuit faults in a timely manner.

[0005] 2. Furthermore, the lines generate a certain amount of heat during transmission. When the internal temperature of the distribution box is too high, it can also cause line faults. In order to reduce line faults, a heat dissipation structure needs to be set up during operation. However, most traditional heat dissipation structures cool down directly by blowing air, and the blown air is directly discharged without being recycled, resulting in a waste of resources.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing line testing devices. Summary of the Invention

[0007] The purpose of this invention is to provide a circuit detection device for distribution boxes, in order to solve the problems mentioned in the background art. Traditional distribution boxes mostly do not have circuit detection devices installed inside. Usually, the circuits inside the distribution box are inspected by construction personnel on a regular basis, so it is impossible to detect circuit faults in time. In addition, traditional heat dissipation structures mostly cool down by blowing air directly, and the blown air is directly discharged without being recycled.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a distribution box line detection device, comprising a box body, a door hinged to the front of the box body, a main line passing through the top of the box body, the bottom of the main line being connected to a branch line via a connector, and the branch line passing through the bottom of the box body;

[0009] It also includes: a fixing box, which is fixedly installed through the top of the enclosure, and a line fault detection mechanism is provided inside the fixing box. The line fault detection mechanism detects the power transmission line by switching contact points. A connecting box is fixedly installed through the back of the enclosure, and a heat dissipation mechanism is provided inside the connecting box. The heat dissipation mechanism is used to dissipate the high temperature generated by the main line and the branch line.

[0010] Preferably, the line fault detection mechanism includes a detection element fixed to the top of the fixed box, and a first motor is installed on the side of the fixed box. The output shaft of the first motor is connected to a connecting shaft. When the first motor drives the output shaft to rotate, it can wind up the connecting rope.

[0011] Preferably, connecting ropes are symmetrically arranged on the outer side of the connecting shaft, and two adjacent connecting shafts are connected to each other by a pulley mechanism. The end of the connecting rope away from the connecting shaft is fixed at the corner of the movable platform. When the connecting rope is wound up, it drives the movable platform to rise, and when the winding of the connecting rope is released, the movable platform descends.

[0012] Preferably, the movable platform and the fixed box form a relative lifting structure, and the lower part of the movable platform is connected to the first terminal block. Support plates are fixed at both ends of the movable platform, and the support plates are provided with second terminal blocks. When the movable platform descends, it drives the first terminal block to be energized, and when the movable platform rises, it drives the second terminal block to be energized.

[0013] Preferably, the main line is electrically connected to both the first and second terminals, and the support plate and the fixing rod are elastically slidably connected. The fixing rod is fixed to the inner top surface of the fixed box. During the lifting and lowering of the movable platform, the support plate can slide on the fixing rod, and the spring's elasticity can cause the movable platform to automatically return to its original position.

[0014] Preferably, the heat dissipation mechanism includes a second motor installed at the bottom of the connecting box, and a fan blade is fixedly installed on the output shaft of the second motor. The fan blade is located at the upper end inside the connecting box. When the second motor drives the fan blade to rotate, it can generate gas, thereby achieving heat dissipation.

[0015] Preferably, the middle position of the connecting box is separated by the back of the box body, and a one-way valve is provided at the separation position of the connecting box. The top of the connecting box is connected to the upper heat dissipation ring through the air supply pipe. At the same time, the upper heat dissipation ring is sleeved on the outside of the main line. The gas in the connecting box can be transmitted to the upper heat dissipation ring through the air supply pipe to dissipate heat from the main line.

[0016] Preferably, the upper heat dissipation ring is internally connected to the lower heat dissipation ring through a connecting pipe, and the lower heat dissipation ring is sleeved on the outside of the branch line. The lower heat dissipation rings are evenly spaced, and adjacent heat dissipation rings are connected by pipes. The upper heat dissipation ring transmits gas to the lower heat dissipation ring through the connecting pipe to dissipate heat from the branch line.

[0017] Preferably, the heat dissipation ring at the lower end is connected to the interior of the connecting box through a fixing pipe, and heat dissipation metal wires are fixed at equal intervals on the side of the connecting box away from the housing, and the heat dissipation metal wires pass through the side of the connecting box. When the gas that has absorbed heat flows back into the interior of the connecting box, the heat can be discharged from the connecting box through the heat dissipation metal wires.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the distribution box line detection device, by setting line detection elements inside the distribution box, can periodically detect line faults so as to repair faulty lines in a timely manner. Furthermore, during transmission, the heat generated by the line can be dissipated through gas circulation, thus reducing line faults and improving safety during use. The specific details are as follows:

[0019] 1. The rotating connecting shaft winds up the connecting rope, which in turn lifts the movable platform, separating the first connector and connecting the second connector. This allows the current transmission of the main line to be detected by the detection element, facilitating timely repairs when a fault is detected.

[0020] 2. The air force generated by the fan blade rotation is transmitted through the air supply pipe to the upper heat dissipation ring, absorbing the heat of the main line. Then, it is transmitted through the connecting pipe to the lower heat dissipation ring, absorbing the heat of the branch line. The heated air is then transmitted back to the connecting box through the fixed pipe. The heat comes into contact with the heat dissipation wire, allowing the heat to be dissipated to the outside of the connecting box, thus achieving circulation. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-9 The present invention provides the following technical solution:

[0033] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a distribution box line detection device, comprising a box body 1, a door 2 hinged to the front of the box body 1, a main line 3 passing through the top of the box body 1, the bottom of the main line 3 being connected to a branch line 5 via a connector 4, and the branch line 5 passing through the bottom of the box body 1; further comprising: a fixing box 6 fixedly passing through the top of the box body 1, a line fault detection mechanism being provided inside the fixing box 6, the line fault detection mechanism detecting the transmission line by switching contact points, a connecting box 15 fixedly passing through the back of the box body 1, and a heat dissipation mechanism being provided inside the connecting box 15, the heat dissipation mechanism being used to dissipate the high temperature generated by the main line 3 and the branch line 5.

[0034] Most existing distribution boxes lack internal wiring detection devices. Wiring is typically inspected periodically by construction workers, making it difficult to detect faults in the wiring promptly. Figures 1-4As shown, the line fault detection mechanism includes a detection element 61 fixed to the top of the fixed box 6, and a first motor 7 is installed on the side of the fixed box 6, with the output shaft of the first motor 7 connected to a connecting shaft 8; connecting ropes 9 are symmetrically arranged on the outer side of the connecting shaft 8, and two adjacent connecting shafts 8 are connected to each other through a pulley mechanism, with one end of the connecting rope 9 away from the connecting shaft 8 fixed to the corner of the movable platform 10; the movable platform 10 and the fixed box 6 form a relative lifting structure, and the lower part of the movable platform 10 is connected to the first terminal 11, with support plates 13 fixed at both ends of the movable platform 10, and a second terminal 12 is provided on the support plate 13, the switching contact refers to switching the position of the first terminal 11 and the second terminal 12; the main line 3 is electrically connected to both the first terminal 11 and the second terminal 12, and the support plate 13 and the fixed rod 14 are elastically slidingly connected, with the fixed rod 14 fixed to the fixed box 6. The inner top surface of box 6; During use, the current transmission status of the distribution box can be detected by the line fault detection mechanism. The first motor 7 drives the connecting shaft 8 to rotate, thereby winding the connecting rope 9. During the winding process, the movable platform 10 can be lifted, and the support plate 13 can slide on the fixed rod 14, improving the stability of the movable platform 10. After the movable platform 10 is lifted, the first terminal 11 is separated, and the second terminal 12 is connected. In this way, the current transmission status of the main line 3 can be detected by the detection element 61. When a fault is found, it is convenient to repair it in time. After the detection is completed, the connecting shaft 8 releases the winding of the connecting rope 9. The spring rebound causes the movable platform 10 to descend, and the second terminal 12 is disconnected, so that the first terminal 11 is reconnected, so that the subsequent current can be transmitted to the branch line 5. Therefore, the line fault detection mechanism can detect the line at regular intervals, which can reduce its damage.

[0035] Example 2: During transmission, lines generate heat. Overheating inside the distribution box can cause line faults. To reduce these faults, a heat dissipation structure is needed during operation. However, traditional heat dissipation structures mostly rely on air cooling, and the blown air is directly discharged without being recycled, resulting in resource waste. Therefore, this example uses the following technical solution: Figures 5-9As shown, the heat dissipation mechanism includes a second motor 16 installed at the bottom of the connecting box 15, and a fan blade 17 is fixedly installed on the output shaft of the second motor 16, with the fan blade 17 located at the upper end inside the connecting box 15; the middle position of the connecting box 15 is separated by the back of the housing 1, and a one-way valve is provided at the separation position of the connecting box 15; the top of the connecting box 15 is connected to the upper heat dissipation ring 19 through an air supply pipe 18, and the upper heat dissipation ring 19 is fitted on the outside of the main line 3; the upper heat dissipation ring 19 is connected to the interior of the lower heat dissipation ring 19 through a connecting pipe 20, and the lower heat dissipation ring 19 is fitted on the outside of the branch line 5; the lower heat dissipation rings 19 are evenly spaced, and adjacent heat dissipation rings 19 are connected by pipes; the lower heat dissipation ring 19 is connected to the interior of the connecting box 15 through a fixing pipe 21, and the connecting box 15 is located away from the housing 1. Heat dissipation wires 22 are fixed at equal intervals on both sides of the connecting box 15, and the heat dissipation wires 22 pass through the side of the connecting box 15. Both the main line 3 and the branch line 5 generate heat during use. Therefore, the second motor 16 drives the fan blades 17 to rotate. The resulting airflow can be transmitted through the air pipe 18 to the upper heat dissipation ring 19, thereby absorbing the heat of the main line 3. Then the air continues to be transmitted through the connecting pipe 20 to the lower heat dissipation ring 19, absorbing the heat of the branch line 5. The heated air is then transmitted back to the connecting box 15 through the fixed pipe 21. The heat comes into contact with the heat dissipation wires 22. The heat dissipation wires 22 have good thermal conductivity, which allows the heat to be dissipated from inside the connecting box 15 to the outside. Then the air is transmitted through the one-way valve to the side of the connecting box 15 near the housing 1. The rotation of the fan blades 17 realizes the air circulation, which dissipates heat from the line and reduces the waste of resources.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
