Technical Field
[0001] This utility model relates to the technical field of high-voltage disconnector finger pressure tester equipment, and in particular to a push-type sensor. Background Technology
[0002] In the field of contact finger pressure testing for high-voltage switchgear, accurately measuring the contact pressure of the luffing contact is crucial for ensuring the conductivity and operational safety of the equipment. Traditional contact finger pressure measurement methods suffer from problems such as cumbersome operation and insufficient adaptability. For example:
[0003] Low efficiency of manual operation: Some inspections require manual adjustment of the sensor position point by point, especially when dealing with complex components such as the plum blossom contact, it is difficult to quickly and accurately locate the position, resulting in long inspection time and high labor costs.
[0004] Sensor compatibility limitations: Traditional sensors typically use analog contacts of fixed specifications, which cannot flexibly match the inner diameter of different types of Phillips head contacts. This requires frequent replacement of parts or customized adjustments, affecting detection efficiency.
[0005] Therefore, a push-type sensor needs to be designed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a push-type sensor. This sensor improves ease of operation, adapts to multiple contact specifications, and has a stable structure. Furthermore, the use of limit screws and positioning plates allows for the positioning of the Phillips head contact, facilitating the subsequent installation of the Phillips head contact and the sensor body together using a second bolt.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A push-type sensor includes a connecting post with handles welded to both sides. A connecting plate is welded to the upper end of the connecting post, and a sensor body is provided on the upper end of the connecting plate. The sensor body and the connecting plate are connected by multiple first bolts. The upper end of the sensor body is provided with two stud contacts, each of which has multiple first threaded holes. The upper end of the sensor body is provided with multiple second threaded holes, and multiple first threaded holes and corresponding second threaded holes share a second bolt.
[0009] Preferably, both of the plum blossom contacts are semi-circular, and each of the two plum blossom contacts is provided with an arc-shaped hole and two round holes.
[0010] Preferably, L-shaped plates are fixedly connected to both the left and right sides of the connecting plate, and rectangular plates are fixedly connected to the upper ends of the two L-shaped plates. Guide grooves are provided on the adjacent sides of the two rectangular plates, and the two guide grooves are slidably connected to two positioning plates.
[0011] Preferably, the inner walls of the front two sides of the guide groove on the left side are rotatably connected to a bidirectional lead screw, the bidirectional lead screw passes through two positioning plates, the two positioning plates are threadedly connected to the bidirectional lead screw, and the front side of the bidirectional lead screw extends to the outside and is fixedly connected to a knob.
[0012] Preferably, both rectangular plates are threaded with limit screws.
[0013] Preferably, protective sleeves are provided on adjacent sides of the two limiting screws, and limiting blocks are fixedly connected to adjacent sides of the two positioning plates.
[0014] Compared with existing technologies, the advantages of this device are:
[0015] 1. Compared with existing technologies, by setting handles on both sides of the connecting column, the inspector can easily push the sensor to move by holding the handles, without having to bend over or adjust the posture frequently, which reduces the intensity of manual operation and is especially suitable for inspection scenarios at high altitudes or in confined spaces.
[0016] 2. Compared with the existing technology, the two pentagonal contacts at the top of the sensor body are connected to the sensor body by the second bolt, so that different sizes of pentagonal contacts can be selected and quickly installed on the sensor body according to the test requirements;
[0017] 3. Compared with existing technologies, the use of limit screws and positioning plates allows for quick positioning of the pendulum contact during installation, enabling rapid alignment of the first and second threaded holes and greatly improving the efficiency of pendulum contact replacement.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1
[0024] Reference Figure 1 A push-type sensor includes a connecting post 1, with handles 2 welded to both the left and right sides of the connecting post 1. A connecting plate 3 is welded to the upper end of the connecting post 1, and a sensor body 4 is provided at the upper end of the connecting plate 3. The sensor body 4 and the connecting plate 3 are connected by multiple first bolts. The upper end of the sensor body 4 is provided with two stud contacts 5, each of which is provided with multiple first threaded holes 8. The upper end of the sensor body 4 is provided with multiple second threaded holes, and the multiple first threaded holes 8 and the corresponding second threaded holes are connected by a second bolt.
[0025] Among them, both plum blossom contacts 5 are semi-circular, and each of the two plum blossom contacts 5 is provided with an arc-shaped hole 7 and two round holes 6. A monitoring device is provided on the outside. During the test, the electrical signal generated by the sensor body 4 will be transmitted to the monitoring device, and the monitoring device will save and display the data.
[0026] The functional principle of this utility model can be explained through the following operation: The testing personnel hold the handles 2 on both sides of the connecting column 1 and push the sensor to move by applying force with their hands. The welded structure between the handles 2 and the connecting column 1 forms a stable force transmission path, so that the testing personnel can easily control the sensor to move in complex scenarios such as high altitude and narrow space without frequently bending over or adjusting their posture, which significantly reduces the intensity of manual operation. When it is necessary to adapt to different specifications of plum blossom contacts 5, the two plum blossom contacts 5 at the upper end of the sensor body 4 are connected to the sensor body 4 by the second bolt. The original plum blossom contacts 5 can be quickly disassembled and replaced with the appropriate specifications according to the inner diameter of the contact to be tested.
[0027] Example 2
[0028] Reference Figure 2-3The difference between this embodiment and embodiment 1 is that L-shaped plates 9 are fixedly connected to both the left and right sides of the connecting plate 3, and rectangular plates 10 are fixedly connected to the upper ends of both L-shaped plates 9. Guide grooves 15 are provided on adjacent sides of the two rectangular plates 10. Two positioning plates 12 are slidably connected to the two guide grooves 15. A bidirectional lead screw 14 is rotatably connected to the inner walls of the front sides of the guide groove 15 on the left side. The bidirectional lead screw 14 passes through the two positioning plates 12, and the two positioning plates 12 are threadedly connected to the bidirectional lead screw 14. The front extends to the outside and is fixedly connected to a knob 13. Both rectangular plates 10 are threadedly connected to limit screws 11. The adjacent sides of the two limit screws 11 are provided with protective sleeves. The adjacent sides of the two positioning plates 12 are fixedly connected to limit blocks. When the knob 13 is rotated, the two positioning plates 12 will move relative to each other or away from each other. Then, the limit screws 11 are rotated, so that the two penguin contacts 5 move relative to each other, limiting the penguin contacts 5, so that the first threaded hole 8 and the second threaded hole are quickly aligned, which is convenient for subsequent installation using the second bolt.
[0029] In this embodiment, rotating the knob 13 drives the bidirectional lead screw 14 to rotate, causing the two positioning plates 12 to move relative to each other in the guide groove 15, quickly positioning the plum blossom contact 5 above the sensor body 4. Then, by rotating the limiting screw 11, the two limiting screws 11 move relative to each other, thereby pushing the two plum blossom contacts 5 to move relative to each other. When the two plum blossom contacts 5 come into contact with the limiting block, the first threaded hole 8 of the plum blossom contact 5 is precisely aligned with the second threaded hole of the sensor body 4, and the sensor body 4 and the plum blossom contact 5 can be connected together using the second bolt.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
