[0002] Cable accessories are products that connect cables to power transmission and distribution lines and related distribution devices. They generally refer to the intermediate connections and terminal connections of various cables in cable lines. Together with the cables, they constitute a distribution network. As an important part of the power transmission system, the electrical strength of cable accessories is determined to a certain extent by the interface pressure between the cable accessories and the cable body. Therefore, it is necessary to perform interface pressure testing on cable accessories to ensure the safe operation of the cables.

[0003] The prior art discloses a device for testing interface pressure of distribution cable accessories with patent announcement number CN218674017U. The above patent synchronously measures the radial thickness of the cable accessories, measures and calculates the actual interface pressure value according to the corresponding relationship between the actual radial thickness of the cable accessories and the interface pressure. During the measurement process, the two ranging sensors and the light emitted by the ranging sensors are always in a straight line, and the test data is accurate and the operation is simple. However, in actual use, there are still the following deficiencies: due to the large number of cable accessories, it is not easy for the detection device to fix cable accessories of different specifications, and when detecting cable accessories of different specifications, it is necessary to replace detection probes of different specifications, and the operation process is relatively complicated, which reduces the detection efficiency.

[0004] Therefore, a cable accessory interface pressure detection device is needed to solve the problem that the detection device in the prior art is not easy to fix cable accessories of different specifications, and different detection probes need to be replaced when detecting cable accessories of different specifications.

The operation is simple and effectively avoids the problem that the detection device is difficult to fix cable accessories of different specifications.

[0016] (2) Through the action of the detection mechanism, the forward and reverse rotation of the motor causes the movable plate to drive the installation column to be inserted into the cable accessory. When one side of the installation column collides with one side of the support column inside the cable accessory, the electric push rod is turned on to push the sliding sleeve to move, so that the four T-bars are opened simultaneously inside the cable accessory, thereby causing the pressure sensor to collide with the inner wall of the cable accessory. The detection data is displayed by the pressure measuring instrument, which effectively avoids the problem of replacing different detection probes when detecting cable accessories of different specifications.

A pressure sensor 65 matching the pressure measuring instrument 2 is installed at the center of the top surface of each T-bar 64. A sliding sleeve 66 is slidingly sleeved on the outer surface of the mounting column 61. Second connecting rods 67 are hinged between the outer surfaces of the sliding sleeve 66 and the four T-bars 64 respectively. A limiting ring 68 is tightly sleeved on the outer surface of the mounting column 61.

[0025] Further Figure 1 and Figure 2 As shown, it is worth explaining in detail that the fixing component 7 includes a stepper motor 71, which is fixedly connected to the center of the outer wall of one side of the detection box 1, and the output end of the stepper motor 71 rotates through the one side wall of the detection box 1 and is coaxially fixedly connected with a turntable 72, and the outer wall of the turntable 72 away from the stepper motor 71 is fixedly connected with four support columns 73 with different diameters and distributed in a circle.

[0026] Further Figure 4 As shown, it is worth explaining in detail that four connecting columns 8 distributed in a circle are fixedly connected to the outer wall of one side of the sliding sleeve 66, and the outer wall of the four connecting columns 8 on the side away from the sliding sleeve 66 is fixedly connected to the same fixed disk 9, and the outer wall of the fixed disk 9 on the side away from the connecting columns 8 is coaxially fixedly connected to the output end of the electric push rod 5.

[0027] Further Figure 1 As shown, it is worth explaining in detail that two parallel mounting plates 10 are fixedly connected to the top surface of the detection box 1, and a forward and reverse motor 11 is fixedly connected to the outer wall on one side of one mounting plate 10, and a threaded rod 12 is coaxially fixedly connected to the output end of the forward and reverse motor 11, and the threaded rod 12 rotates through the outer wall on the side away from the forward and reverse motor 11 and penetrates one of the mounting plates 10 and is rotationally connected to the outer wall on the side of the other mounting plate 10, and the threaded rod 12 threadably penetrates the movable plate 4.

Under the action of the thread, the movable plate 4 moves in the through hole 3, and then the movable plate 4 drives the mounting column 61 to move toward the inside of the cable accessory. When the outer wall on one side of the mounting column 61 conflicts with the outer wall on one side of the support column 73 inside the cable accessory, the electric push rod 5 is turned on to push the sliding sleeve 66 on the mounting column 61 to move toward the direction of the support column 73. When the sliding sleeve 66 moves, the cooperation of the second connecting rod 67 and the first connecting rod 63 pushes the four T-shaped rods 64 to open inside the cable accessory. After the pressure sensors 65 arranged on the top surfaces of the four T-shaped rods 64 contact the inner wall of the cable accessory, interface pressure detection is started. The detected data is displayed by the pressure measuring instrument 2, which effectively avoids the problem of replacing different detection probes when detecting cable accessories of different specifications.
