Description

Technical Field

[0001] The utility model relates to the technical field of leakage prevention detection devices, in particular to a leakage prevention detection device used for security weak current engineering. Background Art

[0002] Weak current engineering is a classification of power application. Power application can be divided into two categories according to the strength of power transmission power: strong current and weak current. Security weak current includes closed-circuit monitoring system, anti-theft alarm system, building intercom system, parking lot management system, community card system, infrared perimeter alarm system, electronic fence, patrol system, attendance access control system, security room system, electronic examination room system, smart door lock, etc. In the implementation of security weak current engineering, power distribution cabinets will be used. Since power distribution cabinets are prone to line failure or aging of wires, resulting in leakage in the shell, if not discovered in time, it is easy to cause electric shock to the human body. Therefore, power personnel need to regularly inspect weak current circuits to prevent safety accidents caused by leakage. When conducting inspections, anti-leakage detection devices are usually used.

[0003] Anti-leakage detection devices generally determine whether there is leakage by contacting the conductive sheet with the object to be measured. The conductive sheet is generally exposed to the outside, and its surface is easily covered with dust and water, resulting in poor contact during detection, affecting the accuracy of the detection. It is also easily damaged by collision. Anti-leakage detection devices can generally only detect the outer casing of the distribution cabinet. For the detection of the line, other detection tools need to be used, which is more troublesome. Moreover, anti-leakage detection devices are generally handheld, and the distance between the hand and the object to be measured is close, which is easy to accidentally touch and cause electric shock. The safety is not high, so it is urgently needed to be improved.

[0004] The existing patent (publication number: CN 220455501 U) discloses a leakage detection device for security weak current engineering, which is provided with a rotating rod, an active bevel gear, a driven bevel gear, a first insulating handwheel, a threaded sleeve, a threaded rod, a conductive sheet, a ring sleeve, and a guide rod. During detection, the first insulating handwheel is rotated to make the rotating rod drive the active bevel gear to rotate. Under the transmission action of the active bevel gear and the driven bevel gear, the threaded sleeve is rotated to make the threaded rod drive the conductive sheet to move out from the inside of the chassis, and the ring sleeve slides along the guide rod. After the detection is completed, the first insulating handwheel is rotated in the opposite direction to make the rotating rod drive the active bevel gear to rotate in the opposite direction. Under the transmission action of the active bevel gear and the driven bevel gear, the threaded sleeve is rotated to make the threaded rod drive the conductive sheet to move into the chassis, so that the conductive sheet can be stored, which plays a role of dustproof and waterproof, and can prevent collision.

[0005] However, the above technical solution still has certain defects. In the above patent, the chassis is installed on the base, and four sets of universal wheels are provided at the bottom of the base. The chassis is pushed to move by a push handle. However, when testing the electrical equipment in some computer rooms, there is a threshold at the entrance of the computer room. At this time, the staff is required to lift the entire detection device and cross the threshold. There are many parts in the detection device, and the storage drawer also contains tools, which is heavy. It is very laborious for workers to lift it, which makes it inconvenient to use. For this reason, a leakage prevention detection device for security weak current engineering is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] A leakage detection device for security weak current engineering, such as Figure 1-3 As shown, it includes a housing 100, a detection mechanism 300 is provided on the side wall of the housing 100, and a handheld lifting mechanism 200 is provided at the bottom end of the housing 100;

[0028] The hand-held lifting mechanism 200 includes a grip rod 201, the bottom end of the housing 100 is fixedly connected to the grip rod 201, the inner wall of the grip rod 201 is slidably connected to a lifting rod 202, the bottom end of the lifting rod 202 is fixedly connected to a base 203, the inner wall of the grip rod 201 is provided with two groups of straight grooves 204, the inner walls of the two groups of straight grooves 204 are provided with multiple groups of transverse grooves 205, the outer wall of the lifting rod 202 is fixedly connected to two groups of fixed blocks 206, and the outer walls of the two groups of fixed blocks 206 are respectively slidably connected to the inner walls of the multiple groups of transverse grooves 205, and the grip rod 201 is provided with two groups of straight grooves 204, and the inner walls of the two groups of straight grooves 204 are provided with multiple groups of transverse grooves 205. A T-shaped slot 207 is provided at the bottom end of the rod 201, and a T-shaped rail 208 is rotatably connected to the inner wall of the T-shaped slot 207, and a swivel 209 is fixedly connected to the bottom end of the T-shaped rail 208. Two sets of sliding slots 210 are provided on the outer wall of the lifting rod 202, and two sets of sliders 211 are fixedly connected to the inner wall of the swivel 209, and the outer walls of the two sets of sliders 211 are respectively slidably connected to the inner walls of the two sets of sliding slots 210, and a torsion spring 212 is fixedly connected to the top end of the swivel 209, and one end of the torsion spring 212 is fixedly connected to the bottom end of the grip rod 201.

[0029] When the height of the detection device needs to be adjusted in order to detect objects at different heights, the base 203 only needs to be placed on the ground, and then the grip 201 is rotated. When the grip 201 is rotated, the two sets of fixed blocks 206 can be rotated from the transverse groove 205 into the straight groove 204. Since the slider 211 is located inside the sliding groove 210, the grip 201 will not drive the swivel 209 to rotate. At this time, the grip 201 can be moved upward or upward to drive the detection device to adjust the height. When the detection device is adjusted to a suitable level, only the grip 201 needs to be released. At this time, the torsion spring 212 can drive the grip 201 to reset and rotate, so that the fixed block 206 re-enters the corresponding transverse groove 205. At this time, the height of the detection device is fixed. When the grip 201 is rotated.

[0030] Please refer to Figure 4-5The detection mechanism 300 includes a conductive plate 301. The conductive plate 301 is provided on the right side of the housing 100. A threaded sleeve 302 is fixedly connected to the right side of the housing 100. A screw rod 303 is threadedly connected to the inner wall of the threaded sleeve 302. The right end of the screw rod 303 is fixedly connected to the left outer wall of the conductive plate 301. The left end of the screw rod 303 extends to the inside of the housing 100. A conductive ring 304 is rotatably sleeved on the outer wall of one end of the screw rod 303 located inside the housing 100. An electric control board 306 is fixedly connected to the top of the housing 100. A conductive rod 305 is fixedly connected to the top of the conductive ring 304. The top end of the conductive rod 305 is electrically connected to the bottom end of the electric control board 306, the top end of the electric control board 306 is electrically connected to a warning light 307, the top end of the electric control board 306 is located on one side of the warning light 307 and is electrically connected to a voltmeter 308, the inner wall of one end of the screw rod 303 located inside the shell 100 is slidably connected to a rectangular rod 3091, the end of the rectangular rod 3091 is fixedly connected to a rotating shaft 309, and the left end of the rotating shaft 309 extends to the outside of the shell 100, the inner wall of the rotating shaft 309 is slidably connected to a semicircular rod 310, and the end of the semicircular rod 310 is fixedly connected to a crank 311.

[0031] When it is necessary to perform leakage detection on the surface of an object, it is only necessary to rotate the screw rod 303. The screw rod 303 will drive the conductive plate 301 to move to the outside of the housing 100 through the threaded connection with the threaded sleeve 302. When the conductive plate 301 contacts the surface of the object to be detected, if the surface of the object has leakage, the current can be transmitted to the screw rod 303 through the conductive plate 301, and then transmitted from the screw rod 303 to the conductive ring 304, and the conductive ring 304 is then transmitted to the electric control board 306 through the conductive rod 305. When the electric control board 306 is energized, the warning light 307 will light up, thereby reminding the operator that the device has leakage. The brighter the warning light 307 is, the higher the leakage voltage is. At the same time, the current will be transmitted to the voltmeter 308, so that the operator can observe the leakage voltage. When there is no leakage in the object, the electric control board 306 will not be energized, and the warning light 307 will not light up.

[0032] Please refer to Figure 4-5 The inner wall of the rotating shaft 309 is provided with two groups of sliding grooves, and the inner walls of the two groups of sliding grooves are slidably connected with arc heads 312, the top ends of the two groups of arc heads 312 are fixedly connected with limit springs, and the top ends of the two groups of limit springs are fixedly connected to the inner walls of the two groups of sliding grooves, and the top end of the semicircular rod 310 is provided with two groups of arc grooves 313, and the two groups of arc heads 312 are respectively matched with the two groups of arc grooves 313.

[0033] When it is necessary to detect an object, the operator needs to stay away from the object to be detected to prevent electric shock. He only needs to pull the crank handle 311 backward to drive the semicircular rod 310 to move. When the pulling force is greater than the friction force of the arc head 312 on the arc groove 313, the arc groove 313 can squeeze the arc head 312 into the interior of the slide groove. When the right arc groove 313 moves to the bottom of the left arc head 312, the left arc head 312 will be pushed into the right arc groove 313 by the limit spring, and the pulling of the crank handle 311 can be stopped. At this time, the crank handle 311 is the object to be detected, and the operator can stay away from the object to be detected and turn the crank handle 311. The crank handle 311 drives the rotating shaft 309 to rotate through the semicircular rod 310, and the rotating shaft 309 drives the rectangular rod 3091 to rotate. The rectangular rod 3091 can drive the screw rod 303 to rotate, thereby making the conductive plate 301 move toward the direction of the object to be detected until the conductive plate 301 is in contact with the outer surface of the object to be detected.

[0034] Please refer to Figure 1 The housing 100, the grip 201 and the crank 311 are all made of plastic insulating material.

[0035] The housing 100, the grip 201 and the crank 311 are all made of plastic insulating material to prevent the operator from getting an electric shock.

[0036] During use, when the detection device needs to be used, the entire device can be easily picked up by holding the handle 201, and when the object to be detected needs to be detected, the height of the conductive plate 301 can be adjusted by rotating the handle 201, and after loosening the handle 201, the height of the conductive plate 301 can be automatically fixed, which is very convenient to use. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
