Description

Technical Field

[0001] The utility model relates to the field of cable joint monitoring, in particular to a cable joint temperature detector. Background Art

[0002] The main function of the cable joint is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint so that it can operate safely and reliably. If the seal is poor, not only will the oil leak and cause the oil-impregnated paper to dry up, but moisture will also invade the inside of the cable, causing its insulation performance to deteriorate.

[0003] Existing cable joints may become hot after long-term use. If they remain hot for a long time, it may be detrimental to the surrounding environment and may even spontaneously combust. Existing cable joints generally have a thermometer tied to them to monitor their temperature, which is troublesome to install.

[0004] Therefore, we need to develop a cable joint temperature detector that is easy to install. Utility Model Content

[0005] In order to overcome the disadvantage that the existing temperature detectors are generally directly tied to the cable joints, which makes installation more troublesome, the utility model provides a cable joint temperature detector that is easy to install.

[0006] The technical solution of the utility model is: a cable joint temperature detector, including a protective cover, a temperature detector, screws, a sliding rod, an arc-shaped clamping plate and a second spring. The two protective covers are fixed by four screws. The temperature detector is slidably provided on the right protective cover. The front and rear sides of the two protective covers are slidably provided with sliding rods. The side of the sliding rod away from the protective cover is equipped with an arc-shaped clamping plate. The second spring is sleeved on the sliding rod, and the two ends of the second spring are respectively connected to the protective cover and the arc-shaped clamping plate.

[0007] As an improvement of the above scheme, it also includes a fixed block, a clamping rod and a first spring. The fixed block is installed on the right protective cover, the fixed block is installed on the front side of the temperature detector, a clamping rod is slidably provided on the fixed block, the clamping rod is sleeved with a first spring, and both ends of the first spring are respectively connected to the fixed block and the clamping rod.

[0008] As an improvement of the above solution, it also includes a fixing plate and a fan. The rear side of the protective cover is equipped with a fixing plate, and a plurality of fans are installed on the fixing plate.

[0009] As an improvement of the above solution, a plurality of heat dissipation holes are provided on the protective cover.

[0010] As an improvement of the above solution, a rubber pad is also included, and the rubber pads are installed on the front and rear sides of the protective cover.

[0011] As an improvement to the above solution, a gasket is slidably provided on the screw.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model moves the arc-shaped clamping plates on both sides outward, causing the second spring to contract, but the arc-shaped clamping plates are squeezed inward under the action of the second spring, so that the arc-shaped clamping plates can fix the protective cover to the cable connector, thereby achieving the effect of conveniently fixing the temperature detector.

[0013] 2. The utility model stretches the first spring by pulling the clamping rod. When the clamping rod is separated from the thermometer, the thermometer is pulled upward, and then the clamping rod is released. Under the action of the first spring, the clamping rod is clamped back into the thermometer, thereby achieving the effect of adjusting the height of the thermometer.

[0019] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0020] Example 1

[0021] A cable joint temperature detector, such as Figure 1-Figure 4As shown, it includes a protective cover 1, a temperature detector 2, a screw 6, a sliding rod 7, an arc-shaped clamping plate 8, a second spring 9, a fixing plate 10, a fan 11 and a rubber pad 13. The two protective covers 1 are fixed by four screws 6. A gasket is slidably provided on the screw 6 to prevent the nut from falling off when tightening. The right protective cover 1 is slidably provided with a temperature detector 2. The front and rear sides of the two protective covers 1 are slidably provided with sliding rods 7. The side of the sliding rod 7 away from the protective cover 1 is equipped with an arc-shaped clamping plate 8. The sliding rod 7 is sleeved with a second spring 9. Second spring 9, the second spring 9 can enable the arc-shaped clamping plate 8 to fix the protective cover 1 to the cable connector, the two ends of the second spring 9 are respectively connected to the protective cover 1 and the arc-shaped clamping plate 8, a fixing plate 10 is installed on the rear side of the protective cover 1, a plurality of fans 11 are installed on the fixing plate 10, and there are two fans 11 on each fixing plate 10, a plurality of heat dissipation holes 12 are opened on the protective cover 1, and rubber pads 13 are installed on the front and rear sides of the protective cover 1, and the rubber pads 13 can prevent the staff from slipping when installing the two protective covers 1.

[0022] When it is necessary to install the thermometer 2 on the cable connector, first dock the two thermometers 2 onto the cable connector, then pass the screws 6 through the two protective covers 1, and tighten the screws 6. While the two thermometers 2 are docked, the arc-shaped clamping plates 8 on both sides will move outward. The movement of the arc-shaped clamping plates 8 will cause the second spring 9 to contract, but the arc-shaped clamping plates 8 will be squeezed inward under the action of the second spring 9, so that the arc-shaped clamping plates 8 can fix the protective cover 1 to the cable connector. When the temperature of the cable connector is too high, the thermometer 2 will sound an alarm, and then the fan 11 will be started. Under the action of the fan 11, the temperature inside the protective cover 1 will drop, and the wind blown by the fan 11 will be discharged through the heat dissipation holes 12.

[0023] Example 2

[0024] On the basis of Example 1, Figure 3 As shown, it also includes a fixed block 3, a clamping rod 4 and a first spring 5. The fixed block 3 is fixedly installed on the right protective cover 1, and the fixed block 3 is installed on the front side of the temperature detector 2. A clamping rod 4 is slidably provided on the fixed block 3, and the clamping rod 4 can clamp the temperature detector 2. A first spring 5 is sleeved on the clamping rod 4, and the first spring 5 can reset the clamping rod 4. The two ends of the first spring 5 are respectively connected to the fixed block 3 and the clamping rod 4.

[0025] When it is necessary to perform temperature measurement and monitoring on a larger cable joint, pull the clamping rod 4 to stretch the first spring 5. When the clamping rod 4 is separated from the thermometer 2, pull the thermometer 2 upward, then release the clamping rod 4. Under the action of the first spring 5, the clamping rod 4 will be clamped back into the thermometer 2, so that the temperature of the larger cable joint can be monitored.

[0026] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
