Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, and more specifically, to a temperature detection device moving on the surface of a cable. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. Cables have the characteristics of internal power supply and external insulation. They are one of the main components of modern power transmission lines. Cables are exposed to the outdoors for a long time and need to be regularly inspected and maintained. During the inspection, the temperature of the cable needs to be detected. Therefore, a temperature detection device is needed to detect the cable temperature to ensure the normal use of the cable and extend its service life.

[0003] However, there are various types of temperature detection devices in the prior art. For example, utility model patent CN213148123U relates to a temperature detection device for power cables. The utility model is provided with a base, a group of supports are connected on both sides of the base, buckles are connected on both sides of the base through the supports, a semicircular through hole is opened at one end of the base, semicircular grooves are opened at the two ends of the semicircular through hole at the top of the base, positioning columns are connected to the four corners of the top of the base, a control mainboard is connected to one side of the top of the base, a temperature sensor is connected to the middle of one side of the semicircular through hole and both ends of the other side of the top of the base, and a cover plate is connected to the top of the base through the positioning column. This device effectively reduces the influence of the external environment on the cable temperature detection, improves the accuracy of the temperature detection data, and detects three different positions at the same time to obtain multiple temperature values, effectively reducing the error of the detection data. This device is light in structure and easy to carry and use, making circuit maintenance work faster and more efficient.

[0004] Although the temperature detection device can detect multiple temperature data at the same time and is easy to carry and use, the device is fixed to the cable surface by two clamps and a cover plate during use, and is difficult to move freely on the cable surface. It is not convenient to perform multi-point temperature detection on different positions of the cable. The operation is not simple enough and the use is limited. In order to avoid this phenomenon, it is necessary to design a temperature detection device that moves on the cable surface. Utility Model Content

The ends of the two movable rods close to each other are fixedly connected with splints through the connecting seat, and the splints are located in the connecting rings. Anti-slip rubber pads are provided on the inner sides of the two splints.

[0009] Preferably, the compression spring is fixed on the connecting seat, the movable rod passes through the compression spring, the compression spring is in a compressed state and presses the connecting seat, and the ends of the two movable rods that are away from each other are fixedly connected with pull rings, and the pull rings are located outside the connecting ring.

[0010] Preferably, a cable body is provided through the first half ring and the second half ring, and the surface of the cable body is in contact with the inner side of the anti-slip rubber pad.

The operation is simple and convenient, and the practicability is strong. After the detection device moves to the corresponding position, release the pull ring. Since the compression spring is in a compressed state, the rebound elasticity of the compression spring is used to press the clamping plate, so that the anti-skid rubber pad is tightly attached to the cable, and the anti-skid property of the anti-skid rubber pad is used to position the moving device, thereby preventing the device from slipping arbitrarily during detection to ensure the stability of the device.

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 , Figure 2 as well as Figure 3 As shown, it is a structural schematic diagram of the temperature detection device moving on the cable surface in this embodiment.
