Technical Field

[0001] The present invention relates to the technical field of distribution box inspection equipment, and in particular to an inspection device for a distribution box and a detection method thereof. Background Art

[0002] The distribution box is a low-voltage distribution box that is assembled in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. The circuit can be connected or disconnected by manual or automatic switches during normal operation. In case of failure or abnormal operation, the circuit can be cut off or an alarm can be given with the help of protective devices. The measuring instruments can display various parameters in operation, and some electrical parameters can be adjusted. It can also prompt or send signals when the box deviates from the normal working state. After the production and processing of the distribution box is completed, it needs to be tested. The detection scope includes factory inspection, quality test, IP grade inspection, insulation resistance inspection, waterproof and dustproof inspection, and fire prevention inspection. The current distribution boxes are mostly shaped by stamping metal sheets, and in order to increase the pressure-bearing capacity of the distribution box, the edges are mostly curled.

[0003] However, after stamping and curling, the elastic force of the metal will force the compressed position to rebound slightly, especially the corner of the distribution box door. Due to the influence of the metal elasticity, the angle of the corner of the distribution box door will expand, affecting the closing effect of the distribution box door and the distribution box. To solve the above problems, the following solutions are proposed. Summary of the invention

[0005] Preferably, the positive angle detection component includes an oil pipe that passes through and is connected to the side wall of the hydraulic box, and an arc-shaped hydraulic rod is connected to the end of the oil pipe away from the hydraulic box. The bottom of the arc-shaped hydraulic rod is fixedly connected to the top of the U-shaped bracket, and the end of the arc-shaped hydraulic rod away from the U-shaped bracket is fixedly connected to a sliding bracket. When using the device, the electric telescopic rod 1 is fixed at the required position, and the distribution box door to be detected is placed at the bottom of the device, and the power supply of the electric telescopic rod 1 is turned on. The electric telescopic rod 1 generates an extension force, forcing the push rod and the piston plate to slide downward along the inner wall of the shell. The solution inside the shell is pressurized into the hydraulic rod, and the hydraulic rod generates an extension force, and forces the piston plate 2 to squeeze the hydraulic box and the fixed plate to move outward. At this time, the fixed plate drives the slide rail bracket and the rotating column 1 to contact the corner of the distribution box door, presenting a Figure 1 In the state shown, the staff then turns on the power of the electric telescopic rod 2, and the electric telescopic rod 2 generates a contraction force, forcing the U-shaped bracket and the slider to move toward the center of the equipment along the inner wall of the slider. The slider drives the outer push rod to slide through the rotating column 2, and the outer push rod will push the folding plate 1 to contact the inner wall of the distribution box door. If the inner wall of the distribution box door is concave inward at this time, the concave position will contact the side of the pressure detector 1, and the pressure detector 1 is pushed by the outer push rod, and the pressure on the pressure detector 1 increases.

The characteristic of the above-mentioned piston plate 2 pushing the fixed plate and the slide rail bracket to move outward is utilized, and a hydraulic box and a piston plate 2 are arranged inside the equipment. When the slide rail bracket contacts the inner wall of the distribution box door, the piston plate 2 will press the solution inside the hydraulic box into the arc hydraulic rod through the oil pipe, forcing the arc hydraulic rod to extend outward, and the arc hydraulic rod drives the folding plate 2 to rotate downward through the sliding bracket and the rolling column, so as to move the folding plate 2 from Figure 2 state, transforming into Figure 1The folding plate 2 is in the state of being covered on the outer wall of the distribution box door. At this time, the electric telescopic rod 2 generates a contraction force, and the electric telescopic rod 2 drives the sliding bracket to move deeper into the equipment through the U-shaped bracket, and the sliding bracket drives the rolling column to move along the slide groove on the top of the folding plate 2, so that the folding plate 2 is folded inward and forces the pressure detector 2 to contact the outer wall of the distribution box door. By detecting the pressure change transmitted by the pressure detector 2, it can effectively detect whether the outer wall of the box door is protruding. Through the above detection of the inner and outer walls of the distribution box door, it can quickly check whether there is deformation at the corner of the distribution box door.

[0007] Preferably, the cleaning assembly also includes a fixing rod fixedly connected to the top of the slide rail bracket, the top of the fixing rod is fixedly connected to an air pressure box, and the outer wall of the air pressure box is fixedly connected to a one-way valve.

[0008] Preferably, a piston ring is slidably connected to the inner wall of the air pressure box, and a pressure tube is fixedly connected to the side wall of the piston ring. After the detection is completed, the electric telescopic rod 2 generates an extension force to make the pressure detector 2 and the pressure detector 1 close to the distribution box door, and the electric telescopic rod 1 generates a contraction force to force the piston plate to move upward along the inner wall of the shell. At the same time, the hydraulic rod and the piston plate 2 are reset. At this time, the piston plate 2 contracts along the inner wall of the hydraulic box, and the solution inside the arc-shaped hydraulic rod is reset through the oil pipeline. At this time, the arc-shaped hydraulic rod will drive the folding plate 2 and the pressure detector 2 to tilt upward, and the piston plate 2 drives the fixed plate and the slide rail bracket to contract, completing the rapid disengagement of the equipment.

[0010] Preferably, the cleaning component also includes a slide groove provided at the side wall of the contact block, a compression spring is fixedly connected to the inner wall of the slide groove, a slide plate is fixedly connected to the other end of the compression spring, an air outlet hole is provided at the outer wall of the slide plate, and a cleaning component is arranged inside the device by utilizing the force of the above-mentioned fixed plate extending outward, and before the rotating column contacts the inner wall of the distribution box door, the contact block will first contact the inner wall of the distribution box door, and with the movement of the slide rail bracket, the pressure tube will slide along the inner wall of the air pressure box, and in this process, the internal air of the pressure tube will be compressed , and high-pressure gas is formed inside the air storage tank. When the rotating column 1 contacts the inner wall of the distribution box door, the side wall of the air pressure box will contact the side wall of the slide plate, and the slide plate will slide along the inner wall of the slide groove, forcing the air outlet to overlap with the air outlet hole to form a gap, and the high-pressure gas inside the air storage tank will be discharged outward through the above gap and act on the inside of the distribution box door, and the high-pressure gas flows outward along the inner wall of the distribution box door, effectively removing most of the residual impurities. Through the application of the above components, the residual impurities can be prevented from affecting the detection accuracy of the pressure detector 1.

[0011] A detection method for a distribution box inspection device comprises the following steps: S1: When in use, fix the electric telescopic rod 1 at the desired position, place the distribution box door to be tested at the bottom of the device, turn on the power of the electric telescopic rod 1, and the electric telescopic rod 1 generates an extension force, forcing the push rod and the piston plate to slide downward along the inner wall of the shell; S2: The solution inside the shell is pressed into the hydraulic rod, which generates an extension force and forces the second piston plate to squeeze the hydraulic box and the fixed plate to move outward. At this time, the fixed plate drives the slide rail bracket and the rotating column 1 to contact the corner of the distribution box door; S3: The staff then turns on the power of the electric telescopic rod 2, which generates a contraction force, forcing the U-shaped bracket and the slider to move toward the center of the device along the inner wall of the slider. The slider drives the outer push rod to slide through the rotating column 2, and the outer push rod pushes the folding plate 1 to contact the inner wall of the distribution box door.

[0012] The present invention has the following beneficial effects: (1) The present invention aims to solve the problem that the corner curling position may be deformed after the iron sheet is stamped. A pressure detector is provided inside the device. When the device is used, the electric telescopic rod is fixed at the required position, and the distribution box door to be tested is placed at the bottom of the device. The power of the electric telescopic rod is turned on, and the electric telescopic rod generates an extension force, forcing the push rod and the piston plate to slide downward along the inner wall of the shell. The solution inside the shell is pressurized into the hydraulic rod, and the hydraulic rod generates an extension force, forcing the piston plate 2 to squeeze the hydraulic box and the fixed plate to move outward. At this time, the fixed plate drives the slide rail bracket and the rotating column 1 to contact the corner of the distribution box door, presenting the following Figure 1In the state shown, the staff then turns on the power of the electric telescopic rod 2, and the electric telescopic rod 2 generates a contraction force, forcing the U-shaped bracket and the slider to move toward the center of the equipment along the inner wall of the slider. The slider drives the outer push rod to slide through the rotating column 2, and the outer push rod will push the folding plate 1 to contact the inner wall of the distribution box door. If the inner wall of the distribution box door is concave inward at this time, the concave position will contact the side of the pressure detector 1, and the pressure detector 1 is pushed by the outer push rod, and the pressure on the pressure detector 1 increases. Through the application of the upper component and the feedback of the data of the pressure detector 1, it can be quickly identified whether the inner wall of the distribution box door is protruding, thereby improving the detection efficiency of the equipment.

[0013] (2) The present invention utilizes the characteristic that the piston plate 2 pushes the fixed plate and the slide rail bracket to move outward. A hydraulic box and a piston plate 2 are arranged inside the equipment. When the slide rail bracket contacts the inner wall of the distribution box door, the piston plate 2 will press the solution inside the hydraulic box into the arc-shaped hydraulic rod through the oil pipe, forcing the arc-shaped hydraulic rod to extend outward. The arc-shaped hydraulic rod drives the folding plate 2 to rotate downward through the sliding bracket and the rolling column, and the folding plate 2 is moved from Figure 2 state, transforming into Figure 1 The folding plate 2 is in the state of being covered on the outer wall of the distribution box door. At this time, the electric telescopic rod 2 generates a contraction force, and the electric telescopic rod 2 drives the sliding bracket to move deeper into the equipment through the U-shaped bracket, and the sliding bracket drives the rolling column to move along the slide groove on the top of the folding plate 2, so that the folding plate 2 is folded inward and forces the pressure detector 2 to contact the outer wall of the distribution box door. By detecting the pressure change transmitted by the pressure detector 2, it can effectively detect whether the outer wall of the box door is protruding. Through the above detection of the inner and outer walls of the distribution box door, it can quickly check whether there is deformation at the corner of the distribution box door.

[0014] (3) The present invention utilizes the outward extension force of the above-mentioned fixed plate and provides a cleaning component inside the equipment. Before the rotating column 1 contacts the inner wall of the distribution box door, the contact block will first contact the inner wall of the distribution box door, and as the slide rail bracket moves, the pressure tube will slide along the inner wall of the air pressure box. During this process, the internal air of the pressure tube will be compressed and high-pressure gas will be formed inside the air storage tank. When the rotating column 1 contacts the inner wall of the distribution box door, the side wall of the air pressure box will contact the side wall of the slide plate. The slide plate slides along the inner wall of the slide groove, forcing the air outlet to overlap with the air outlet hole to form a gap, and the high-pressure gas inside the air storage tank will be discharged outward through the above-mentioned gap and act on the inside of the distribution box door. The high-pressure gas flows outward along the inner wall of the distribution box door, effectively removing most of the residual impurities. Through the application of the above-mentioned components, the residual impurities can be prevented from affecting the detection accuracy of the pressure detector 1.

[0015] (4) After the detection is completed, the electric telescopic rod 2 generates an extension force to make the pressure detector 2 and the pressure detector 1 separate from the distribution box door, and the electric telescopic rod 1 generates a contraction force to force the piston plate to move upward along the inner wall of the shell. At the same time, the hydraulic rod and the piston plate 2 are reset. At this time, the piston plate 2 contracts along the inner wall of the hydraulic box, and the solution inside the arc-shaped hydraulic rod is reset through the oil pipeline. At this time, the arc-shaped hydraulic rod will drive the folding plate 2 and the pressure detector 2 to tilt upward, and the piston plate 2 drives the fixed plate and the slide rail bracket to contract, completing the rapid separation of the equipment. Through the application of the above components, the separation efficiency of the equipment is improved, and excessive component design is avoided to affect the operating efficiency of the equipment.

If the inner wall of the distribution box door is concave inward at this time, the concave position will contact the side of the pressure detector 1 26, and the pressure detector 1 26 is pushed by the outer push rod 34, and the pressure on the pressure detector 1 26 increases. Through the application of the upper component, through the pressure detector The feedback of the data of the measuring instrument 26 can quickly identify whether the inner wall of the distribution box door is protruding, thereby improving the detection efficiency of the equipment. The characteristics of the piston plate 215 pushing the fixed plate 22 and the slide rail bracket 23 to move outward are utilized. A hydraulic box 21 and a piston plate 215 are arranged inside the equipment. When the slide rail bracket 23 contacts the inner wall of the distribution box door, the piston plate 215 will press the solution inside the hydraulic box 21 into the arc hydraulic rod 42 through the oil pipe 41, forcing the arc hydraulic rod 42 to extend outward. The arc hydraulic rod 42 drives the folding plate 245 to rotate downward through the sliding bracket 43 and the rolling column 44, and the folding plate 245 is moved from Figure 2 state, transforming into Figure 1 The folding plate 2 45 is wrapped around the outer wall of the distribution box door. At this time, the electric telescopic rod 2 16 generates a contraction force. The electric telescopic rod 2 16 drives the sliding bracket 43 to move deeper into the equipment through the U-shaped bracket 17. The sliding bracket 43 drives the rolling column 44 to move along the slide groove on the top of the folding plate 2 45, so that the folding plate 2 45 is folded inward and forces the pressure detector 2 46 to contact the outer wall of the distribution box door. By detecting the pressure change transmitted by the pressure detector 2 46, it can be effectively detected whether the outer wall of the box door is protruding. Through the above detection of the inner and outer walls of the distribution box door, it can quickly check whether there is deformation at the corner of the distribution box door.

[0029] By utilizing the outward extension force of the above-mentioned fixed plate 22, a cleaning component 5 is arranged inside the equipment. Before the rotating column 24 contacts the inner wall of the distribution box door, the contact block 56 will first contact the inner wall of the distribution box door, and with the movement of the slide rail bracket 23, the pressure tube 55 will slide along the inner wall of the air pressure box 52. During this process, the internal air of the pressure tube 55 will be compressed and high-pressure gas will be formed inside the air storage groove 57. When the rotating column 24 contacts the inner wall of the distribution box door, the side wall of the air pressure box 52 will contact the side wall of the slide plate 511, and the slide plate 511 slides along the inner wall of the slide groove 59, forcing the air outlet 58 to overlap with the air outlet through hole 512 to form a gap, and the high-pressure gas inside the air storage groove 57 will be discharged outward through the above-mentioned gap and act on the inside of the distribution box door, and the high-pressure gas flows outward along the inner wall of the distribution box door, effectively removing most of the residual impurities. Through the application of the above-mentioned components, the residual impurities can be prevented from affecting the detection accuracy of the pressure detector 26.

[0030] After the detection is completed, the electric telescopic rod 16 generates an extension force, so that the pressure detector 46 and the pressure detector 26 are separated from the distribution box door, and the electric telescopic rod 13 generates a contraction force, forcing the piston plate 11 to move upward along the inner wall of the outer shell 1, and at the same time the hydraulic rod 14 and the piston plate 15 are reset. At this time, the piston plate 15 contracts along the inner wall of the hydraulic box 21, and the solution inside the arc hydraulic rod 42 is reset through the oil pipe 41. At this time, the arc hydraulic rod 42 will drive the folding plate 45 and the pressure detector 46 to tilt upward, and the piston plate 15 drives the fixed plate 22 and the slide rail bracket 23 to contract, completing the rapid separation of the equipment. Through the application of the above components, the separation efficiency of the equipment is improved, and excessive component design is avoided to affect the operating efficiency of the equipment.
