Description

Technical Field

[0001] The utility model relates to the technical field of clamping force detection, in particular to a disconnector clamping force detection device. Background Technique

[0002] A disconnector is a switching device mainly used for "isolating power sources, switching operations, and connecting and disconnecting small-current circuits" without arc-extinguishing function. When the disconnector is in the open position, there is an insulating distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time.

[0003] At present, some existing disconnectors need to be assisted by an external housing for support during normal use to connect the circuit. Therefore, when testing the clamping force, it is necessary to install it first and then test the clamping force inside the housing. Most of the existing clamping force testing devices need to install the switch structure inside the testing device before testing, which is likely to conflict with the use of the above-mentioned disconnector, affecting the normal clamping force testing of the device, and thus making the use of the measuring device relatively limited. Content of the Utility Model

[0004] The purpose of the utility model is to provide a disconnector clamping force detection device to solve the problems raised in the above background technique. To achieve the above purpose, the utility model provides the following technical solution: A disconnector clamping force detection device includes an installation frame. Anti-slip plates are slidably installed on both the left and right sides of the installation frame. An installation bottom plate is slidably installed inside the installation frame. A sliding block is slidably installed inside the installation bottom plate. A display screen is rotatably installed at the upper end of the sliding block. A second threaded rod is rotatably installed inside the first threaded rod. A pressure tester is rotatably installed at the side end of the second threaded rod. A second rotating motor is installed at the side end of the sliding block.

[0005] Further preferably, driving motors are fixedly installed on both the left and right sides of the installation frame. A driving rod is slidably installed at the side end of each driving motor.

[0007] Further preferably, reserved slots are provided on both the left and right sides of the installation bottom plate. A first threaded rod is rotatably installed inside the installation bottom plate. A first rotating motor is rotatably installed at the side end of the first threaded rod.

[0008] Further preferably, the mounting base plate is slidably mounted inside the mounting frame by cooperating with the protrusions on the inner wall of the mounting frame through the reserved slots opened on the left and right sides, and support legs are fixedly mounted at the lower end of the mounting base plate.

[0009] Further preferably, a fixing ring is fixedly mounted at the upper end of the sliding block, a rotating rod is rotatably mounted inside the fixing ring, and a display screen is mounted at the side end of the rotating rod.

[0010] Further preferably, a second transmission gear is rotatably mounted at the rear side end of the sliding block, a first rotating gear is rotatably mounted at the side end of the second rotating motor, the first rotating gear meshes with the second transmission gear, and the pressure tester is in signal communication with the display screen.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the support legs cooperate with the pushing motors on both sides to push the anti-slip plates to clamp and fix the device body, and then cooperate with the first rotating motor to drive the first threaded rod to rotate, thereby cooperating with the sliding block to push for position transformation, so as to facilitate the measurement of disconnectors of different sizes inside the device during use, thereby improving the use efficiency of the device and enhancing the practicality of the device.

[0013] In the present utility model, after the position of the sliding block is confirmed, the pressure tester installed at the side end of the second threaded rod is attached to the connecting plate, and then the second rotating motor is started. The second rotating motor drives the first rotating gear to rotate, thereby driving the engaged second transmission gear to rotate, and then cooperating with the second threaded rod to push the pressure tester to squeeze towards the connecting plate. Furthermore, data analysis and processing are carried out between the pressure tester and the display screen, so as to facilitate and quickly test the clamping force of the disconnector during the use of the device and improve the use effect of the device.
