[0002] With the rapid development of society, economy, and human science, the responsibilities and roles of electricity are becoming increasingly important. However, with the introduction of various nonlinear electrical appliances, the degree of harmonic pollution in the power system is constantly increasing, which poses a huge threat to the safe transmission of electricity. Therefore, it is necessary to use power detection devices to detect voltage changes in the lines in order to make rapid adjustments.

[0003] The fixed support device for power testing equipment is an auxiliary device used to fix and support the power testing equipment, making it convenient to use. In the existing technology, when the power testing equipment tests the electricity meter, it is necessary to manually adjust the level, then position and clamp the electricity meter before testing. After the test is completed, the tested electricity meter still needs to be removed manually, which is labor-intensive and inefficient. Therefore, there is a need in the market for a clamping system that can automatically level and clamp the electricity meter without requiring manual removal. Summary of the Invention

[0014] Step A: Place the test meter on the mounting plate. The motor drives the mounting plate to rise through the lead screw. The upper wedge block and the inclined plate control the movable ball to push the test meter. Then, the movable ball is used to level the test meter. The clamping frame clamps the test meter.

[0015] Step B: The inclined plate pushes the piston rod through the connecting plate, and the piston rod cleans the dust from the detection port on the surface of the meter through the piston cylinder;

[0016] Step C: As the mounting plate lifts the test meter, the detector is inserted into the test port to perform power testing;

[0017] Step D: After the test is completed, the screw controls the mounting plate to descend, the first spring controls the drive plate to reset, and the push plate pushes the test meter onto the bearing plate. Under the action of the push plate, the test meter falls into the interior of the housing through the arc plate.

[0018] Preferably, in step D, after the meter completes the test, as the mounting plate descends, the magnetic block rotates under the magnetic force of the magnet, and at this time the clamping frame will not clamp the meter.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention clamps the electricity meter by setting up a clamping assembly. The upper wedge block pushes the inclined plate to move to the right, the drive plate drives the limit plate to move to the right via the drive rod, the limit plate drives the push rod to move to the right, the push rod pushes the detection meter via the push plate, and the detection meter is leveled by several movable balls. The drive rod drives the hinge plate to rotate, and the mating frame clamps the detection meter through the clamping frame, thereby realizing the clamping operation of the detection meter. Compared with existing equipment, this invention has a simple structure. The clamping of the electricity meter can be achieved by the cooperation between the inclined plate and the wedge block, without the need for manual additional fixing and limiting.

[0021] 2. This invention cleans the dust from the test meter by setting up a cleaning component. The connecting plate drives the piston rod to move to the right, and the piston rod controls the piston cylinder to spray air onto the test port, thereby achieving dust removal from the test port and further improving the accuracy of the test results.

[0022] 3. This invention uses a sealing assembly to transport the test meter. After testing, the motor controls the mounting plate to descend. Under the action of the second spring, elastic block, and drive rod, the clamping frame releases its grip on the test meter. The inclined plate begins to move to the right under the action of the lower wedge block, and the magnetic block rotates to the left under the action of the magnet. The magnetic block no longer grips the test meter, and the test meter falls into the opening of the arc plate. The L-shaped plate pushes the cover plate to the surface of the test meter. Under the action of the mounting plate and the lead screw, the L-shaped plate moves to the right and downwards simultaneously. While moving, the L-shaped plate applies pressure to the test meter. After being subjected to pressure, the test meter falls into the interior through the arc-shaped opening of the arc plate, thereby collecting the test meter and further improving the portability of this device.

There are four sets of elastic rods 304 arranged in a front-back and left-right manner, and an opening is formed between the four sets of arc blocks 303.

[0042] To prevent excessive rotation of the magnetic block 215, a limiting block 13 is fixedly connected to the upper end face of the mounting plate 6 on the left side of the magnetic block 215 to limit its movement. To reduce the heat generated during operation, a matching rod 4 is fixedly connected to the lower end face of the motor 3 on the left side of the lead screw 7, and a cooling fan 5 is fixedly installed on the left side of the lead screw 7.

[0043] A clamping method for a clamping system used for testing electricity meters, the method comprising the following steps:

[0044] Step A: Place the test meter 9 on the mounting plate 6. The motor 3 drives the mounting plate 6 to rise through the lead screw 7. The upper wedge block 201 and the inclined plate 203 control the movable ball 218 to push the test meter 9. Then, the movable ball 218 is used to level the test meter 9. The clamping frame 213 clamps the test meter 9.

[0045] Step B: The inclined plate 203 pushes the piston rod 402 through the connecting plate 401, and the piston rod 402 cleans the dust from the detection port 106 on the surface of the test meter 9 through the piston cylinder 403;

[0046] Step C: As the mounting plate 6 drives the test meter 9 to rise, the detector 104 is inserted into the test port 106 to perform power detection;

[0047] Step D: After the test is completed, the lead screw 7 controls the mounting plate 6 to descend, the first spring 206 controls the drive plate 205 to reset, and the push plate 208 pushes the test meter 9 onto the support plate 307. Under the action of the push plate 302, the test meter 9 falls into the interior of the housing 1 through the arc plate 301.

[0048] Furthermore, after the test meter 9 completes the test in step D, as the mounting plate 6 descends, the magnetic block 215 rotates under the magnetic force of the magnet 10. At this time, the clamping frame 213 will not clamp the test meter 9.

[0049] Working principle: After installing this device, place the test meter 9 to be tested on the mounting plate 6. Turn on the control switch of the motor 3. The output end of the motor 3 drives the lead screw 7, which is fixedly connected to it, to rotate. The lead screw 7 drives the mounting plate 6 to move upward. During the upward movement of the mounting plate 6, the upper wedge block 201 pushes the inclined plate 203 to move to the right. The inclined plate 203 drives the drive plate 205, which is fixedly connected to it, to move to the right. The drive plate 205 drives the drive rod 207, which is fixedly connected to it, to move to the right. The drive rod 207 drives the limit plate 210 to move to the right. The limit plate 210 drives the push rod 216, which is fixedly connected to it, to move to the right. Push rod 216 pushes test meter 9 through push plate 208. When test meter 9 pushes movable ball 218, under the action of third spring 221, movable ball 218 levels test meter 9. Drive rod 207 drives hinge plate 217 to rotate. Hinge plate 217 controls mating frame 212 to rotate. Mating frame 212 drives clamping frame 213 to move, thereby realizing the clamping work of two sets of clamping frames 213. Magnetic block 215 clamps test meter 9. The opening between the two sets of clamping frames 213 further clamps and limits clamping member 105, thereby realizing the clamping work of test meter 9.

[0050] The inclined plate 203 also drives the connecting plate 401 fixedly connected to it to move to the right. The connecting plate 401 drives the piston rod 402 fixedly connected to it to move to the right. The piston rod 402 controls the piston cylinder 403 to spray air onto the detection port 106, thereby realizing the dust removal work of the detection port 106 and further improving the accuracy of detection.

[0051] The detector 104 is inserted into the detection port 106, and then the power detection begins. The detection information is transmitted to the detector 104 through the transmission rod 101. The detector 104 remotely sends the detection results to the staff, thereby realizing the power detection work of the detection meter 9.

[0052] After the test is completed, the motor 3 rotates in the reverse direction, and the lead screw 7 controls the descent of the mounting plate 6. Under the action of the second spring 209, the elastic block 214, and the drive rod 207, the clamping frame 213 releases its grip on the test meter 9. As the mounting plate 6 continues to move downward, the inclined plate 203 begins to move to the right under the action of the lower wedge block 202. The clamping frame 213 continues to perform the clamping work. The magnetic block 215 rotates to the left under the action of the magnet 10. Therefore, the magnetic block 215 does not clamp the test meter 9. The push plate 208 pushes the test meter 9 to the surface of the support plate 307. The fourth spring 306 is stretched and contracted under the force. The support plate 307 rotates to the left under the action of the push plate 302. The test meter 9 falls into the opening of the arc plate 301 due to the inclination of the support plate 307.

[0053] The limiting plate 210 drives the fixing rod 310 to move to the right. The fixing rod 310 drives the L-shaped plate 309 fixedly connected to it to move to the right. The L-shaped plate 309 pushes the cover plate 308 inside the transport frame 11. The cover plate 308 falls on the surface of the test meter 9. Under the action of the mounting plate 6 and the lead screw 7, the L-shaped plate 309 moves to the right and also moves downward. While moving, the L-shaped plate 309 applies pressure to the test meter 9. After being subjected to pressure, the test meter 9 falls through the arc-shaped opening of the arc plate 301 onto the arc block 303. Then, under the action of the four sets of arc blocks 303 and the elastic rod 304, it falls into the interior of 1, thus completing the test of the test meter 9.
