Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric inspection equipment, in particular to an electric tester for electrical maintenance in power plants. Background Technique
[0002] An electric tester is an instrument for detecting whether an object is charged and roughly estimating the magnitude of the charge. Its typical structure is shown in the left figure. When the object to be tested contacts the conductor at the top of the electric tester, the charge it carries will be transmitted to the foil in the glass bell jar. Due to the mutual repulsion of like charges, the foil will automatically separate and form a certain angle.
[0003] Chinese Patent with publication number CN217879408U discloses an electric testing device for electrical maintenance in power plants, including: a clamping assembly, on both sides of the top of the clamping assembly, insulating hanging arm assemblies are fixedly installed, and an electric tester is clamped by the clamping part of the clamping assembly; the clamping assembly includes a bottom plate, and a bottom bearing strip is fixedly installed at a lower position on the front surface of the bottom plate. For this electric testing device for electrical maintenance in power plants, if the equipment nearby or the equipment itself uses iron or other adsorbable metals for support, the electromagnet can be directly turned on to generate suction force, and then, the device can be fixed by magnetic adsorption through the electromagnet. Also, the cabinet door can be opened, and the U-shaped head can be hung on the cabinet door to limit the position of the device. These two methods can limit the position of the device, that is, when performing electric testing, there is no need to hold the electric tester by hand, and the electric tester can be closer to the user's line of sight, making it more convenient to view the value on the electric tester.
[0004] The above patent has the following problems: The electric testing device for electrical maintenance in power plants is hung on the cabinet door through a U-shaped head, so that subsequent workers do not need to hold the electric tester by hand. However, when most U-shaped heads are hung on the outer surface of the cabinet, the U-shaped head is prone to move during use, resulting in the need for subsequent workers to support the electric tester during the operation of the electric tester, thus reducing the practicability of the device.

[0062] Embodiment:
[0063] As Figures 1-5 shown, an electroscope for electrical maintenance in a power plant includes an electroscope 1, a positioning mechanism 2, a limiting mechanism 3, a mounting mechanism 4, a clamping mechanism 6, and a fixing mechanism 7.
[0064] The positioning mechanism 2 includes a fixing plate, a mounting bracket 202, an L-shaped limiting plate 203, a first lifting motion driving assembly, and a second lifting motion driving assembly.
[0065] The fixing plate is a square frame-shaped fixing plate 201; an electroscope 1 is clamped inside the square frame-shaped fixing plate 201.
[0066] The first lifting motion driving assembly includes a U-shaped connecting plate 205, a motor 206, a threaded rod 204, and a slider 209. The second lifting assembly is a double-acting electric telescopic rod 207.
[0067] A clamping groove is formed in the front surface of the mounting bracket 202. The upper end of the U-shaped connecting plate 205 is fixedly connected to the lower end of the mounting bracket 202. A motor 206 is fixedly provided on the inner wall of the U-shaped connecting plate 205; the output shaft of the motor 206 is fixedly connected to the lower end of the threaded rod 204. The threaded rod 204 passes through the mounting bracket 202, through holes are formed in the bottom and top of the inner wall of the clamping groove of the mounting bracket 202, and the threaded rod 204 is rotatably connected inside the through holes of the mounting bracket 202. The outer circumference of the threaded rod 204 is threadedly connected to the slider 209; the slider 209 is slidably arranged in the clamping groove. The front surface of the slider 209 is fixedly connected to the back surface of the fixing plate.
[0068] A groove is formed in the back surface of the mounting bracket 202; a double-acting electric telescopic rod 207 is installed inside the groove. The upper output end and the lower output end of the double-acting electric telescopic rod 207 are respectively fixedly connected to the L-shaped limiting plate 203. Clamping grooves are formed on the opposite end faces of the two limiting plates; positioning pulleys 208 are respectively rotatably arranged in the two clamping grooves; the upper surface of the positioning pulley 208 is flush with the surface of the opposite end face of the limiting plate.
[0069] Specifically, by starting the positioning mechanism 2, the electroscope 1 is clamped and installed on the front side of the power distribution cabinet, and then by pushing the positioning mechanism 2 and starting the positioning mechanism 2 to drive the electroscope 1 to move at multiple angles on the front side of the power distribution cabinet, the use range of the electroscope 1 is expanded, so the practicability of the electroscope 1 is improved.
[0070] When the positions of the two groups of L-shaped limit plates 203 are respectively adjusted and moved to the upper and lower ends of the power distribution cabinet at the rear end of the electrical appliance tester 1, the output ends of the bidirectional electric telescopic rods 207 are started to drive the two groups of L-shaped limit plates 203 to move, so that the inner walls of the opposite end faces of the two L-shaped limit plates 203 are respectively abutted and attached to the upper and lower sides of the power distribution cabinet at the rear end of the electrical appliance tester 1. Then, by starting the motor 206, the motor 206 drives the threaded rod 204 to rotate. When the threaded rod 204 rotates, it drives the slider 209, the square frame-shaped fixing plate 201 and the electrical appliance tester 1 to move up and down on the front side of the mounting frame 202. Thus, when the subsequent electrical appliance tester 1 is installed on the front side of the power distribution cabinet, its position can be adjusted up and down, thereby expanding the detection range of the subsequent electrical appliance tester 1, and improving the practicability of the device. By pushing the mounting frame 202 to drive the opposite end faces of the two directional pulleys to slide on the upper and lower sides of the power distribution cabinet respectively, the subsequent staff can drive the electrical appliance tester 1 to move left and right on the front side of the power distribution cabinet by pushing the mounting frame 202. Thus, when the positioning mechanism 2 positions the electrical appliance tester 1 on the front side of the power distribution cabinet, the position of the electrical appliance tester 1 can be adjusted at multiple angles, thereby expanding the use range of the electrical appliance tester 1, and improving the practicability of the electrical appliance tester 1.
[0071] Installation mechanisms 4 are respectively arranged on both sides of the fixing plate. The installation mechanism 4 includes a clamping plate 403, an electric telescopic rod 402 and an L-shaped fixing plate 401. Clamping plates 403 are arranged on both sides of the electrical appliance tester 1. The two groups of clamping plates 403 are respectively clamped inside the grooves on both sides of the square frame-shaped fixing plate 201. A clamping groove is formed at the bottom of the inner wall of the square frame-shaped fixing plate 201. The bottom ends of the two groups of clamping plates 403 are both slidably connected inside the clamping groove of the square frame-shaped fixing plate 201. L-shaped fixing plates 401 are fixedly arranged on the outer walls on both sides of the square frame-shaped fixing plate 201. Electric telescopic rods 402 are respectively fixedly arranged on the inner end faces on both sides of the two L-shaped fixing plates 401. Through holes are respectively formed on the left and right sides of the square frame-shaped fixing plate 201. The output ends of the electric telescopic rods 402 on both sides respectively pass through the through holes of the square frame-shaped fixing plate 201 and are fixedly connected to the clamping plates 403. The electric telescopic rod 402 is rotationally connected to the L-shaped fixing plate 401.
[0072] Specifically, when the subsequent electrical appliance tester 1 with a smaller volume is placed inside the square frame-shaped fixing plate 201, by starting the two groups of electric telescopic rods 402 to push the two groups of clamping plates 403 to slide inside the clamping groove of the square frame-shaped fixing plate 201, the opposite end faces of the two clamping plates 403 are respectively abutted against the left and right sides of the electrical appliance tester 1, so that the two groups of installation mechanisms 4 limit the positions of electrical appliance testers 1 with various volumes inside the square frame-shaped fixing plate 201. Thus, after the subsequent electrical appliance tester 1 and the positioning mechanism 2 are disassembled, the positioning mechanism 2 can be clamped on the outer ends of multiple electrical appliance testers 1, thereby expanding the use range of the positioning mechanism 2, and improving the practicability of the device.
[0073] Grooves are provided on the opposite end surfaces of the clamping plates 403 on both sides, and rubber pads 5 are embedded in the grooves of the clamping plates 403 on both sides. Specifically, the two rubber pads 5 are arranged between the two clamping plates 403, so that when the two clamping plates 403 clamp the electroscope 1 with a smaller volume inside the U-shaped fixing plate 201, the two rubber pads 5 protect the contact surfaces between the two clamping plates 403 and the electroscope 1, thereby preventing the two clamping plates 403 from excessively squeezing the two sides of the electroscope 1 and causing damage to the electroscope 1.
[0074] The distance between the two L-shaped limiting plates 203 is adjusted by the electric telescopic rod 402 , so that the L-shaped fixing plate 401 can be clamped on the outer surface of various types of distribution cabinets during use, thereby expanding the positioning range of the positioning mechanism 2 .
[0075] A limiting mechanism 3 is provided at one side end of the mounting frame 202. The limiting mechanism 3 includes a fixed block 301, a fixed rod 302, a screw 303 and a positioning block 304. A fixed block 301 is fixedly provided at one side end of the mounting frame 202. A through hole and a threaded hole are provided on the front of the fixed block 301, and a fixing rod 302 is passed through the through hole of the fixed block 301, and the fixing rod 302 is rotatably connected to the fixed block 301. The back of the fixing rod 302 is fixedly connected to the front of the positioning block 304. The screw 303 is threadedly connected to the inside of the fixed block 301. A through hole is provided on the front of the positioning block 304, and the back of the screw 303 is rotatably connected to the inside of the through hole of the positioning block 304.
[0076] Specifically, when the subsequent positioning mechanism 2 is installed at the outer end of the distribution cabinet, the inner walls of the two L-shaped limit plates 203 are respectively attached to the back of the distribution cabinet by pulling the mounting frame 202, and then the positioning block 304 is pushed to move by rotating the screw 303, and the back of the positioning block 304 is abutted against the front of the distribution cabinet, so that the limiting mechanism 3 limits the moving position of the two L-shaped limit plates 203 at the upper and lower ends of the distribution cabinet, thereby minimizing the forward and backward movement of the subsequent electrical tester 1 on the front side of the distribution cabinet during use.
[0077] The lower end of the mounting frame 202 is provided with a clamping mechanism 6. The clamping mechanism 6 includes a back plate 612, a U-shaped connecting plate 601, a horizontal motion driving assembly and a positioning plate 602. The horizontal motion driving assembly includes a bidirectional threaded rod 603, a hydraulic cylinder 604, a gear 1 605, a gear 2 606, a rotating rod 607, a gear 3 608, a connecting rod 609, a bevel gear 1 610 and a bevel gear 2 611. The upper end of the back plate 612 is fixedly connected to the lower end of the mounting frame 202. The front of the back plate 612 is fixedly connected to the back of the U-shaped connecting plate 601.
[0078] Gear 2 606 is fixedly provided on the outer circumference of the output shaft of the motor 206. Gear 2 606 and the gear 1 605 are meshed with each other; the upper end of the gear 1 605 is fixedly connected to the output end of the hydraulic cylinder 604; the hydraulic cylinder 604 is rotatably arranged inside the lower end of the mounting frame 202. Gear 1 605 and gear 3 608 are meshed with each other. The upper end of the gear 3 608 is fixedly connected to the lower end of the rotating rod 607; the rotating rod 607 is rotatably arranged inside the lower end of the mounting frame 202. The lower end of the mounting frame 202 limits the hydraulic cylinder 604 and the rotating rod 607 at the same time to prevent the hydraulic cylinder 604 and the rotating rod 607 from falling. The lower end of the rotating rod 607 is rotatably connected to the connecting rod 609. The lower end of the connecting rod 609 is fixedly connected to the upper end of the bevel gear 1 610. The bevel gear 1 610 and the bevel gear 2 611 are meshed with each other. A bidirectional threaded rod 603 is rotatably arranged inside the U-shaped connecting plate 601. The outer peripheral surface of the bidirectional threaded rod 603 is fixedly connected to the second bevel gear 611. Positioning plates 602 are respectively threadedly connected to the external threads on both sides of the bidirectional threaded rod 603.
[0079] Specifically, the gear 2 606 is installed on the outer surface of the output shaft of the motor 206, so that the subsequent motor 206 drives the gear 2 606 to drive the gear 1 605, the gear 3 608, the bevel gear 1 610 and the bevel gear 2 611 to rotate during the startup process, and the bevel gear 2 611 drives the two-way threaded rod 603 to rotate during the rotation, and the two-way threaded rod 603 drives the two positioning plates 602 to move during the rotation, and the opposite end faces of the two positioning plates 602 are respectively abutted against the left and right sides of the power distribution cabinet at the rear end of the electroscope 1, so that the clamping mechanism 6 limits and positions the left and right movement position of the electroscope 1 during use, thereby minimizing the left and right swinging of the subsequent electroscope 1 during use.
[0080] At the same time, when the subsequent staff adjusts the position of the mobile electroscope 1 at the front end of the mounting frame 202, the hydraulic cylinder 604 is started to drive the gear 1 605 to move upward, and the external teeth of the gear 1 605 and the external teeth of the gear 2 606 are disconnected, so as to avoid the subsequent staff from driving the two sets of positioning plates 602 to move when the motor 206 is started to adjust the position of the mobile electroscope 1. By starting the motor 206 to synchronously drive the two sets of positioning plates 602 to move when adjusting the position of the mobile electroscope 1, the energy expenditure consumed by the subsequent clamping mechanism 6 during use is reduced, thereby improving the practicality of the device.
[0081] The fixing mechanism 7 includes an L-shaped connection block 701 and a bolt 702. The L-shaped connection block 701 is fixedly provided on the side end of the connection plate away from the limiting mechanism 3; the bolt 702 is threadedly connected to the L-shaped connection block 701 along the length direction of the bidirectional threaded rod 603. A threaded hole is provided through the connection plate along the length direction of the bidirectional threaded rod 603; the positions of the threaded hole and the bolt 702 correspond, and the bolt 702 can be passed through the threaded hole.
[0082] Specifically, when the subsequent gear three 608 and gear one 605 are disconnected, the bolt 702 is passed through the threaded hole by rotating the bolt 702; the inner end of the bolt 702 abuts against the outer end face of the two-way threaded rod 603, so that the fixing mechanism 7 limits the rotation position of the two-way threaded rod 603 inside the two sets of through holes of the U-shaped connecting plate 601, thereby minimizing the rotation of the gear three 608 when the subsequent gear three 608 and gear one 605 are disconnected, causing the two sets of positioning plates 602 to move, thereby improving the stability of the clamping mechanism 6 during use.
[0083] A control device 8 is fixed to the upper end of the U-shaped fixing plate 201, and the output end of the motor 206 is electrically connected to the input end of the control device 8; the output end of the electric telescopic rod 402 is electrically connected to the input end of the control device 8; the output end of the bidirectional electric telescopic rod 207 is electrically connected to the input end of the control device 8.
[0084] Specifically, by operating the control device 8, the control device 8 controls the starting motor 206 and the bidirectional electric telescopic rod 207, so that the staff does not need to run back and forth during the installation of the positioning electroscope 1, thereby reducing the labor consumed by subsequent staff when installing the positioning electroscope 1.
[0085] Working principle:
[0086] By starting the two-way electric telescopic rod 207 to pull the two groups of L-shaped limit plates 203 to move, the inner walls of the opposite sides of the two groups of L-shaped limit plates 203 are respectively abutted against the upper and lower sides of the power distribution cabinet at the rear end of the electroscope 1, and then the threaded rod 204 is triggered by starting the motor 206 to drive the slider 209, the U-shaped fixing plate 201 and the electroscope 1 to move up and down on the front side of the mounting frame 202, so that the position of the subsequent electroscope 1 when installed on the front side of the power distribution cabinet can be adjusted up and down, thereby expanding the detection range of the subsequent electroscope 1; by pushing the mounting frame 202, the adjacent sides of the two groups of directional pulleys are driven to slide on the upper and lower sides of the power distribution cabinet respectively, so that the subsequent staff can drive the electroscope 1 to move left and right on the front side of the power distribution cabinet by pushing the mounting frame 202, so that the position of the electroscope 1 can be adjusted at multiple angles when the positioning mechanism 2 positions the electroscope 1 on the front side of the power distribution cabinet, thereby expanding the use range of the electroscope 1.
[0087] Meanwhile, by pulling the mounting bracket 202, the inner walls of the two groups of L-shaped limiting plates 203 are respectively attached to the back of the power distribution cabinet. Then, by rotating the screw rod 303, the positioning block 304 is pushed to move, and the back of the positioning block 304 is abutted and attached to the front of the power distribution cabinet, so that the limiting mechanism 3 restricts the moving positions of the two groups of L-shaped limiting plates 203 at the upper and lower ends of the power distribution cabinet, thereby minimizing the subsequent front-back movement of the electroscope 1 on the front side of the power distribution cabinet during use; by starting the two groups of electric telescopic rods 402, the two groups of clamping plates 403 are pushed to slide inside the slots of the square frame-shaped fixing plate 201, and the adjacent sides of the two groups of clamping plates 403 are respectively abutted against the left and right sides of the electroscope 1, so that the two groups of mounting mechanisms 4 restrict the positions of electroscopes 1 of various volumes inside the square frame-shaped fixing plate 201, so that after the subsequent electroscope 1 and the positioning mechanism 2 are disassembled, the positioning mechanism 2 can be clamped to the outer ends of multiple electroscopes 1, thereby expanding the application range of the positioning mechanism 2.
[0088] In addition, by installing the second gear 606 on the outer surface of the output shaft of the motor 206, when the subsequent motor 206 is started, the second gear 606 is triggered to drive the first gear 605, the third gear 608, the first bevel gear 610 and the second bevel gear 611 to rotate. Then, during the rotation of the second bevel gear 611, the bidirectional threaded rod 603 is driven to trigger the two groups of positioning plates 602 to move, and the two groups of positioning plates 602 are respectively abutted against the left and right sides of the power distribution cabinet at the rear end of the electroscope 1, so that the clamping mechanism 6 restricts and positions the left-right movement position of the electroscope 1 during use, thereby minimizing the left-right swing of the subsequent electroscope 1 during use.
