Description

Technical Field

[0001] This utility model relates to the field of power equipment testing technology, specifically to a portable ball-head ring testing device. Background Technology

[0002] Ball-head rings are circular accessories used to connect insulator strings. During operation, they are affected by both natural environmental factors and human installation factors, which can cause damage, leading to insulator string disconnection and tripping, thus affecting the safe operation of the power grid. Therefore, ball-head rings need to be inspected frequently. Existing daily infrared inspections and drone inspections are difficult to see the wear of the ball-head rings or their potential internal defects due to the inspection angle. Therefore, it is often necessary for workers to climb the power tower to use small ultrasonic equipment to inspect the ball-head rings.

[0003] While existing small ultrasonic devices are convenient for staff to carry, when using them to test ball-head rings, staff need to hold the ultrasonic probe in one hand to place it at different positions on the ball-head ring, while holding the data output terminal in the other hand to observe the test data and complete the test of the ball-head ring. Holding the ultrasonic probe by hand limits the staff's position and range of motion, preventing the ultrasonic probe from contacting the ground-facing surface of the ball-head ring. Furthermore, having both hands occupied makes it inconvenient for staff to operate the data output terminal or perform other operations. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the prior art, handheld ultrasonic probes are inconvenient to access different positions of the ball head ring and occupy the operator's hands, affecting the operator's testing efficiency, and to provide a portable ball head ring testing device.

[0005] To address the shortcomings of the aforementioned technical problems, the present invention provides a portable ball-head ring testing device. This device includes an ultrasonic probe, a data output terminal for display, and a transmission line connecting the data output terminal and the ultrasonic probe. The ultrasonic probe is positioned at the center of a connecting plate. Sliding grooves are provided on both sides of the center of the connecting plate. Sliding blocks slide within each of the two sliding grooves. Clamping plates are provided on the side of each sliding block facing the ultrasonic probe's detection end. A clamping spring is provided between each sliding block and the inner wall of each sliding groove to drive the two clamping plates closer together.

[0006] As a further optimization of the portable ball head ring testing device of this utility model: a protrusion is fixedly provided at the center of the connecting plate, and a stepped hole for engaging with the ultrasonic probe is opened in the protrusion.

[0007] As a further optimization of the portable ball head ring testing device of this utility model: an elastic ring is fixedly provided on the inner wall of the stepped hole, the inner wall of the elastic ring is provided with a rough layer, and the elastic ring is made of elastic rubber.

[0008] As a further optimization of the portable ball-head hanging ring detection device of this utility model: the ends of the two extrusion plates away from the sliding block are inclined from the center to both sides to form flared portions, which allow the clamping plates to quickly connect with the objects to be clamped.

[0009] As a further optimization of the portable ball head ring detection device of this utility model: anti-slip pads are provided on the opposite surfaces of the two clamping plates, and the anti-slip pads are made of rubber.

[0010] As a further optimization of the portable ball head hanging ring testing device of this utility model: both of the sliding grooves are provided with reinforcing columns, the reinforcing columns are slidably engaged with the sliding blocks, and the top pressure springs are wrapped around the reinforcing columns.

[0011] As a further optimization of the portable ball-head ring detection device of this utility model: both ends of the connecting plate are provided with winding posts on the side opposite to the clamping plate in the length direction, and the two winding posts are used for winding and bundling of the transmission line.

[0012] As a further optimization of the portable ball-head hanging ring detection device of this utility model: a grip is fixedly provided at one end of each of the two winding columns away from the connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention uses two clamping springs to press down on the sliding block. During the pressing process, the sliding block's movement trajectory is stabilized by the sliding groove on the connecting plate. Then, the clamping plate connected to the sliding block can clamp the vicinity of the ball head ring, such as the end of the insulator string connected to the ball head ring. Subsequently, the ultrasonic probe, which is clamped at the center of the side of the connecting plate in the width direction, can be positioned at the point to be tested on the ball head ring. This allows the operator to complete the test of the ball head ring simply by holding the data output terminal. At the same time, it also makes it easy for the operator to rotate the ultrasonic probe around the ball head ring for comprehensive testing. Attached Figure Description

[0018] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0019] like Figure 1 or Figure 2 As shown, a portable ball joint ring detection device has a data output terminal 1 for display, monitoring, and control. The data output terminal 1 is equipped with a transmission line 2, which is connected to an ultrasonic probe 6. The ultrasonic probe 6, the data output terminal 1, and the transmission line 2 are easy for workers to carry with them, even when climbing up a transmission tower for use. When needed, workers can press the ultrasonic probe 6 against the ball joint ring to be tested, and the detection information will then be transmitted to the data output terminal 1 via the transmission line 2, allowing workers to hold the data output terminal 1 to observe the data and determine whether the ball joint ring is damaged.

[0020] The ultrasonic probe 6 is mounted on the connecting plate 401. The connecting plate 401 has two symmetrically arranged sliding grooves 402. Sliding blocks 405 slide in each of the two sliding grooves 402. A clamping spring 404 is provided between the opposite ends of the two sliding blocks 405 and the inner walls of the opposite ends of the two sliding grooves 402. A clamping plate 408 is fixedly provided on the side of the two sliding blocks 405 facing the detection end of the ultrasonic probe 6. The two clamping plates 408 can cooperate with the clamping springs 404 and the sliding blocks 405 to clamp the ball head ring near the detection point, thereby positioning the ultrasonic probe 6 at the detection point of the ball head ring. This allows the operator to complete the detection of the ball head ring by simply holding the data output terminal 1. At the same time, the connecting plate 401 can be moved to make the two clamping plates 408 rotate around the ball head ring under the pressure of the clamping springs 404. During this process, the ultrasonic probe 6 will also rotate around the detection point of the ball head ring, making it easier for the operator to fully detect the ball head ring.

[0021] During transport, the two clamping plates 408 can also be clamped onto the data output terminal 1, thereby neatly positioning the transmission line 2 onto the data output terminal 1, making it easier for staff to remove and use it later, and also improving the convenience of carrying and moving it.

[0022] A protrusion 5 is fixedly connected to the center of the connecting plate 401. A stepped hole 501 is opened at the center of the protrusion 5 to engage with the ultrasonic probe 6. The stepped hole 501 makes it easy for staff to insert ultrasonic probes 6 of different models for use. An elastic ring 502 is provided inside the stepped hole 501. The inner wall of the elastic ring 502 is roughened and the elastic ring 502 is made of rubber. This allows the elastic ring 502 to protect the ultrasonic probe 6 and further stabilize the engagement and positioning effect between the stepped hole 501 and the ultrasonic probe 6.

[0023] The connecting plate 401 is provided with a handle 3 on the side opposite to the clamping plate 408. The handle 3 makes it easy for the staff to hold and move the connecting plate 401 to different positions for use. Both ends of the handle 3 in the length direction are provided with winding posts 301 that are fixedly connected to the connecting plate 401. The setting of the two winding posts 301 makes it easy to wind the longer transmission line 2, so as to reduce the situation where the transmission line 2 is too long and obstructs the staff's hand movement, thereby affecting the staff's inspection work.

[0024] The two inner walls of the two sliding grooves 402 of the connecting plate 401 are fixedly connected to the two ends of the reinforcing column 403. The two reinforcing columns 403 are surrounded by the tightening spring 404, thereby maintaining the elastic change shape of the tightening spring 404. The two reinforcing columns 403 are slidably engaged with the sliding block 405 to maintain the stability of the sliding block 405 and the clamping plate 408 connected to the connecting plate 401.

[0025] Both clamping plates 408 are inclined from the inside to the outside on the side facing the detection end of the ultrasonic probe 6 to form a flared part 406. The flared part 406 makes it easy for the operator to connect the two clamping plates 408 with the ball head hanging ring. Then, the connecting plate 401 can be pressed continuously to make the two clamping plates 408 clamp the ball head hanging ring to complete the positioning function of the ultrasonic probe 6.

[0026] Both clamping plates 408 have anti-slip pads 407 on their opposing surfaces. The anti-slip pads 407 are made of rubber, which helps to maintain the friction between the ball head ring and the clamping plate 408 when the clamping plate 408 clamps the ball head ring, thereby improving the stability of the clamping plate 408 clamping the ball head ring area, such as on the insulator string, and thus improving the stability of the ultrasonic probe 6 in positioning the ball head ring to be detected.

[0027] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
