Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, and in particular to safety detection equipment for power distribution. Background Technology

[0002] In power distribution systems, distribution cabinets are critical equipment, and the robustness of the connections between their internal wiring and circuit breakers directly affects the stability and security of the power supply. Traditional methods for checking the tightness of these connections rely primarily on manual pulling of the wires. This method has several drawbacks. Firstly, manual operation is inefficient, consuming significant manpower and time when dealing with a large number of distribution cabinets to test. Secondly, it's difficult to precisely control the force applied when manually pulling the wires, making the test results susceptible to subjective influences. Furthermore, prolonged high-intensity work can lead to fatigue for the testing personnel, resulting in missed detections or misjudgments.

[0003] With the development of the power industry, higher demands are being placed on the efficiency and accuracy of safety inspections of power distribution systems. There is an urgent need for equipment that can overcome the shortcomings of manual inspection and improve inspection efficiency and quality. Utility Model Content

[0004] This utility model provides a safety testing device for power distribution to solve the problem of time-consuming and labor-intensive manual testing of wiring tightness.

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A power distribution safety detection device includes a power distribution cabinet, the power distribution cabinet includes a cabinet body, a switch is installed inside the cabinet body, and a power wire is connected to the switch body. It also includes a pulling mechanism, the pulling mechanism includes a slide block magnetically attracted inside the power distribution cabinet, a slider is slidably connected inside the slide block, and a first swing rod and a second swing rod are symmetrically hinged to the lower part of the slider body. The first swing rod and the second swing rod are symmetrically arranged on both sides of the connection between the power wire and the switch body, and an elastic pull rope is connected between the first swing rod and the second swing rod.

[0007] Both the first and second swing arms are rotatably connected to a turntable at their bottoms. The turntables are projected to coincide in the axial direction and are vertically staggered. When the slider slides on the slide block, both turntables can roll and press against the wire. When the wire is not securely connected, the two turntables can be pulled closer to each other by the elastic pull rope.

[0008] Furthermore, the traction mechanism also includes a first mounting rod and a second mounting rod, wherein the first swing arm and the second swing arm are respectively hinged to the bottom ends of the first mounting rod and the second mounting rod.

[0009] Furthermore, it also includes a limiting mechanism, which includes a winding wire, and a rotating shaft is fixedly connected to both the first and second swing arms and is respectively hinged to the first and second swing arms through the rotating shaft;

[0010] The two take-up cords are respectively wound and connected to the two rotating shafts. When the two take-up cords are pulled up, the two take-up cords are released from the two rotating shafts respectively, so that the first swing arm and the second swing arm move away from each other.

[0011] Furthermore, the limiting mechanism also includes a connecting rope, and both of the take-up lines are fixedly connected to the bottom end of the connecting rope.

[0012] Furthermore, the limiting mechanism also includes a piston cylinder connected to the top of the slider, a piston plate slidably connected inside the piston cylinder, a connecting rope passing through the slider and fixedly connected to the piston plate at its top, an air pipe provided at the upper part of the piston cylinder, and a valve provided on the air pipe. When the valve is closed, the piston plate is limited to the piston cylinder.

[0013] Furthermore, the limiting mechanism also includes a pull rod, which is fixedly connected to the upper surface of the piston plate, and the top of the piston cylinder has a hole that mates with the pull rod.

[0014] Furthermore, it also includes a marking mechanism. The second swing arm has a cavity for containing liquid dye. The marking mechanism includes a nozzle communicating with the cavity of the second swing arm. The nozzle faces the inner wall of the cabinet. The slide has an elongated hole that mates with the nozzle. When the wire connection is not secure, causing the two turntables to move closer to each other due to the pull of the elastic rope, the nozzle sprays pigment onto the inner wall of the cabinet.

[0015] Furthermore, the marking mechanism also includes a rotary switch rotatably connected to the second swing arm and a proximity switch fixedly connected to the second swing arm. The rotary switch is connected to a lever. When the lever is blocked by the wire, the rotary switch rotates, thereby activating the proximity switch. The nozzle is equipped with a solenoid valve. When the proximity switch approaches the wire, the solenoid valve briefly opens.

[0016] Furthermore, a pigment replenishment tube is connected to the second pendulum rod, and the pigment replenishment tube communicates with the cavity of the second pendulum rod.

[0017] Furthermore, the pigment replenishment tube is equipped with a one-way valve.

[0018] The beneficial effects of this utility model are analyzed as follows:

[0019] Safety detection equipment for power distribution includes a distribution cabinet, which includes a cabinet body, a switch installed inside the cabinet, and wires connected to the switch. It also includes a pulling mechanism, which includes a slide block magnetically attached inside the distribution cabinet. A slider is slidably connected inside the slide block. A first swing arm and a second swing arm are symmetrically hinged to the lower part of the slider. The first and second swing arms are symmetrically arranged on both sides of the connection between the wires and the switch, and an elastic pull rope connects the first and second swing arms. A turntable is rotatably connected to the bottom of both the first and second swing arms. The turntables overlap axially and are vertically staggered. When the slider slides on the slide block, both turntables can roll and press against the wires. If the wire connection is not secure, the two turntables can be pulled closer together by the elastic pull rope.

[0020] Place the slide block on top of the circuit breaker, so that the first and second swing arms are located on either side of the connection between the wire and the circuit breaker. At this time, the two turntables are also located on either side of the connection between the wire and the circuit breaker. Then, manually push the slider to slide linearly within the slide block. When the turntables roll on the wire, the tension of the elastic rope on the first and second swing arms can cause the two turntables to tend to move closer to each other. If the connection between the wire and the circuit breaker is firm, the distance between the two turntables will not decrease further. If the connection between the wire and the circuit breaker is not firm, the force of the two turntables moving closer to each other can push the wire into an S-shape, causing the end of the wire to be relatively displaced from the circuit breaker. This indicates that the connection between the wire and the circuit breaker is not firm and needs to be reconnected. Compared with manually pulling the wire to check the connection firmness, this device has higher detection efficiency and is more labor-saving. Attached Figure Description

[0032] Examples, such as Figures 1-5As shown, the power distribution safety detection equipment includes a power distribution cabinet 100, which includes a cabinet body 110. A switch 120 is installed inside the cabinet body 110, and a power cable 130 is connected to the switch 120. The equipment also includes a pulling mechanism 200, which includes a slide block 210 magnetically attached inside the power distribution cabinet 100. A slider 220 is slidably connected inside the slide block 210. A first swing arm 231 and a second swing arm 241 are symmetrically hinged to the lower part of the slider 220. The first swing arm 231 and the second swing arm 241 are symmetrically arranged on the power cable 130. On both sides of the connection with the switch 120, and between the first swing arm 231 and the second swing arm 241, there is an elastic pull rope 260; the bottom of the first swing arm 231 and the second swing arm 241 are rotatably connected to a turntable 250, the turntables 250 are projected to coincide in the axial direction, and the two turntables 250 are vertically staggered. When the slider 220 slides on the slide block 210, the two turntables 250 can roll and press against the wire 130. When the wire 130 is not firmly connected, the two turntables 250 can be pulled closer to each other by the elastic pull rope 260.

[0033] The working principle of the power distribution safety detection equipment provided in this embodiment is as follows:

[0034] After the wire 130 of the cabinet 110 is connected to the switch 120, if it is necessary to test the firmness of the connection, place the slide 210 on top of the switch 120, so that the first swing arm 231 and the second swing arm 241 are respectively located on both sides of the connection between the wire 130 and the switch 120. Activate the magnet control switch on the slide 210 (the principle is the same as the magnet used for the suction mold, which will not be elaborated here; for cabinets 110 made of non-ferromagnetic materials, a structure that does not require the installation of a clothes drying rod can be used to fix the slide 210), so that the slide 210 is firmly attached to the cabinet 110. At this time, the two turntables 250 are also located on both sides of the connection between the wire 130 and the switch 120. Then, manually push the slider 220 to slide linearly inside the slide 210. Since the axial projections of the turntables 250 coincide, and the two turntables... The discs 250 are arranged vertically and alternately. When the discs 250 roll on the wire 130, the tension of the elastic rope 260 on the first swing arm 231 and the second swing arm 241 can make the two discs 250 tend to move closer to each other. If the connection between the wire 130 and the switch 120 is firm, the distance between the two discs 250 will not decrease further. If the connection between the wire 130 and the switch 120 is not firm, the force of the two discs 250 moving closer to each other can push the wire 130 into an S-shape, so that the end of the wire 130 is relatively displaced relative to the switch 120. At this time, it indicates that the connection between the wire 130 and the switch 120 is not firm and needs to be reconnected. Compared with manually pulling the wire 130 to check the connection of the wire 130, the detection efficiency of this device is higher and less labor-intensive.

[0035] Among the optional methods in this embodiment, the more preferred one is:

[0036] The traction mechanism 200 also includes a first mounting rod 230 and a second mounting rod 240, and a first swing rod 231 and a second swing rod 241 are respectively hinged to the bottom ends of the first mounting rod 230 and the second mounting rod 240.

[0037] The first mounting rod 230 and the second mounting rod 240 can slide axially on the slider 220. A nut is threaded onto the slider 220 so that when the nut is tightened, it can abut against the first mounting rod 230 and the second mounting rod 240. This allows the vertical height of the two turntables 250 and the vertical distance between them to be adjustable, so as to be suitable for testing different wiring conditions.

[0038] Regarding the structure of the limit mechanism 300, specifically:

[0039] The limiting mechanism 300 includes a take-up cord 351. A rotating shaft 352 is fixedly connected to both the first swing arm 231 and the second swing arm 241 and is respectively hinged to the first swing arm 231 and the second swing arm 241 through the rotating shaft 352. There are two take-up cords 351, which are respectively wound and connected to the two rotating shafts 352. When the two take-up cords 351 are pulled, the two take-up cords 351 are released from the two rotating shafts 352 respectively, so that the first swing arm 231 and the second swing arm 241 move away from each other.

[0040] To prevent the turntable 250 and the first and second swing arms 231 from interfering with each other during the installation of the slide block 210, when placing the slide block 210, first pull up the two take-up cables 351 so that the two take-up cables 351 are released to the two rotating shafts 352 respectively. As a result, the rotating shafts 352 rotate and drive the first and second swing arms 231 and 241 to swing, so that the two move away from each other and ensure that the placement of the slide block 210 is not interfered with.

[0041] Among the optional methods in this embodiment, the more preferred one is:

[0042] The limiting mechanism 300 also includes a connecting rope 350, and two take-up lines 351 are fixedly connected to the bottom end of the connecting rope 350.

[0043] By pulling the connecting rope 350, both take-up lines 351 can be pulled simultaneously.

[0044] Among the optional methods in this embodiment, the more preferred one is:

[0045] The limiting mechanism 300 also includes a piston cylinder 310 connected to the top of the slider 220. A piston plate 320 is slidably connected inside the piston cylinder 310. A connecting rope 350 passes through the slider 220 and is fixedly connected to the top of the piston plate 320. An air pipe 340 is provided on the upper part of the piston cylinder 310. A valve is provided on the air pipe 340. When the valve is closed, the piston plate 320 is limited to the piston cylinder 310.

[0046] After opening the valve on the air pipe 340, the piston plate 320 can slide upward onto the piston cylinder 310. At this time, the piston plate 320 drives the connecting rope 350 to pull the winding line 351. After controlling the piston plate 320 to slide to a suitable height, the valve on the air pipe 340 is closed, so that the piston plate 320 is not prone to sliding down relative to the piston cylinder 310 due to air pressure, thereby maintaining the first swing rod 231 and the second swing rod 241 in a state of being far apart from each other. After the slide seat 210 is installed, the valve on the air pipe 340 is opened. At this time, the elastic pull rope 260 pulls the first swing rod 231 and the second swing rod 241 closer to each other, and then the firmness of the connection line can be tested.

[0047] Among the optional methods in this embodiment, the more preferred one is:

[0048] The limiting mechanism 300 also includes a pull rod 330, which is fixedly connected to the upper surface of the piston plate 320, and the top of the piston cylinder 310 has a hole that mates with the pull rod 330.

[0049] The hole at the top of the piston cylinder 310 fits tightly against the side wall of the pull rod 330, which reduces the degree of air leakage inside the piston cylinder 310. By pulling the pull rod 330, the piston plate 320 can slide upward, thereby causing the first swing rod 231 and the second swing rod 241 of the Shudie to move away from each other.

[0050] Regarding the structure of the marking mechanism 400, specifically:

[0051] The second swing arm 241 has a cavity for containing liquid dye. The marking mechanism 400 includes a nozzle 440 connected to the cavity of the second swing arm 241. The nozzle 440 faces the inner wall of the cabinet 110. The slide 210 has an elongated hole that mates with the nozzle 440. When the wire 130 is not securely connected, causing the two turntables 250 to move closer to each other due to the pull of the elastic rope 260, the nozzle 440 sprays dye onto the inner wall of the cabinet 110.

[0052] When the turntable 250 comes into contact with the wire 130, if the wire 130 is not securely connected, the wire 130 will be squeezed by the two turntables 250 and become S-shaped. At this time, the nozzle 440 sprays paint onto the cabinet 110 at the position corresponding to the wiring point, which makes it easier to quickly locate the part with the loose wiring and rewire it.

[0053] Among the optional methods in this embodiment, the more preferred one is:

[0054] The marking mechanism 400 also includes a rotary switch 420 rotatably connected to the second rocker arm 241 and a proximity switch 430 fixedly connected to the second rocker arm 241. A lever 421 is connected to the rotary switch 420. When the lever 421 is blocked by the wire 130, the rotary switch 420 rotates, thereby activating the proximity switch 430. A solenoid valve 450 is provided on the nozzle 440. When the proximity switch 430 approaches the wire 130, the solenoid valve 450 opens briefly.

[0055] During the movement of slider 220, if turntable 250 contacts wire 130, lever 421 on rotary switch 420 will also contact the same wire 130. At this time, wire 130 blocks lever 421, causing rotary switch 420 to rotate. Rotary switch 420 then activates proximity switch 430. Thus, when wire 130 is not securely connected, it is squeezed into an S-shape by the two turntables 250. Proximity switch 430 can then approach wire 130, thereby controlling the spray... After the solenoid valve 450 on the head 440 is opened, it closes, causing the pigment to be sprayed onto the inner wall of the cabinet 110. A torsion spring is also sleeved on the second swing arm 241. The two ends of the torsion spring are fixedly connected to the rotary switch 420 and the second swing arm 241, respectively. The wire 130 blocks the lever 421, causing the rotary switch 420 to rotate. The torsion spring is in a torsional state and has potential energy. After the lever 421 moves away from the wire 130, the torsion spring drives the rotary switch 420 to reset, causing the proximity switch 430 to close, ensuring that no errors occur in the subsequent detection process.

[0056] Among the optional methods in this embodiment, the more preferred one is:

[0057] A pigment replenishment tube 410 is connected to the second swing arm 241, and the pigment replenishment tube 410 is connected to the cavity of the second swing arm 241.

[0058] The cavity of the second lever 241 is filled with pigment and has high pressure inside, so that when the solenoid valve 450 is opened, the pigment can be sprayed out through the nozzle 440. When the pigment or pressure is insufficient, pigment is added to the cavity or pressure is increased through the pigment replenishment pipe 410.

[0059] Among the optional methods in this embodiment, the more preferred one is:

[0060] A one-way valve is installed on the pigment replenishment tube 410.

[0061] By installing a one-way valve on the pigment replenishment tube 410, it is convenient to replenish pigment or pressurize the cavity of the second swing rod 241, eliminating the need for the opening and closing process of ordinary valves.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
