DETAILED DESCRIPTION

[0021] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0022] Embodiment 1: A cable temperature detection device, comprising: a first clamp body 1 and a second clamp body 12 arranged in an "X" shape and rotatably connected via a rotating shaft 13, and a temperature measuring device 14 is elastically connected to each of the first clamp body 1 and the second clamp body 12 on one side of the rotating shaft 13 and on the opposite sides of the first clamp body 1 and the second clamp body 12;

[0023] A third elastic member 15 is provided on the other side of the rotating shaft 13 and between the first clamp body 1 and the second clamp body 12. When it is necessary to detect the temperature of the power cable, the staff will hold the first clamp body and the second clamp body with their palms and apply force. When the force is greater than the elasticity of the third elastic member between the first clamp body and the second clamp body, the first clamp body and the second clamp body will rotate around the rotating shaft inside the sliding hole, so that the first clamp body and the second clamp body are close to each other, and then the measuring devices on the first clamp body and the second clamp body are attached to the cable surface. The first elastic member on the side wall of the measuring device will make the measuring device fit closely to the cable surface. The elastic force of the elastic member between the measuring device and the first clamp body and the second clamp body will push the measuring device toward the direction of the cable, and then measure;

[0024] A pull rope 4 is provided on the side of the temperature measuring device 14 opposite to the third elastic member 15 and between the first clamp body 1 and the second clamp body 12. When the measuring device clamps the cable, the pull rope will first come into contact with the cable. As the measuring device further clamps, the pull rope will fit against the surface of the cable. As the length of the pull rope is pulled, the two ends of the pull rope will pull the ends of the first clamp body and the second clamp body, so that the measuring device fits more closely against the cable surface.

[0025] The first clamp body 1 and the second clamp body 12 are each provided with a plurality of limit holes 52 along their length direction, and a movable plate 53 is slidably connected inside one end of the first clamp body 1 and the second clamp body 12 away from the temperature measuring device 14, and the movable plate 53 is elastically connected to a limit block 54 that cooperates with the limit hole 52.

[0026] The movable plate 53 is provided with a receiving groove 55, the limiting block 54 is slidably mounted inside the receiving groove 55, and a second elastic member 51 is disposed between the inner wall of the receiving groove 55 and the limiting block 54;

[0027] When the movable plate is adjusted to a suitable length, the accommodating groove is aligned with the limiting hole. At this time, the limit block extends from the accommodating groove under the elastic force of the second elastic member, and the limit block is located in the accommodating groove and the limiting hole, so that the position of the movable block is fixed, which can be used to extend the power arms of the first clamp body and the second clamp body, thereby reducing the requirement on the hand-holding force of the personnel.

[0028] A plurality of first elastic members 2 are respectively disposed between the temperature measuring device 14 and the first clamp body 1 and the second clamp body 12 .

[0029] A first magnet 3 is disposed between the rotating shaft 13 and the temperature measuring device 14 and on the first pliers 1, and a second magnet 31 matching the first magnet 3 is disposed on the second pliers 12;

[0030] When the first clamp body is close to the second clamp body, the distance between the first magnet and the second magnet will also be close as the first clamp body and the second clamp body are close to each other. At this time, the first magnet and the second magnet will be attracted to each other.

[0031] A sliding hole 11 is defined in the middle of the first pliers body 1 , and the rotating shaft 13 is disposed inside the sliding hole 11 . The middle of the second pliers body 12 is located inside the sliding hole 11 and sleeved on the rotating shaft 13 .

[0032] Embodiment 2: A cable temperature detection device, comprising: a first clamp body 1 and a second clamp body 12 arranged in an "X" shape and rotatably connected via a rotating shaft 13, and a temperature measuring device 14 is elastically connected to each of the first clamp body 1 and the second clamp body 12 on one side of the rotating shaft 13 and on the opposite sides of the first clamp body 1 and the second clamp body 12;

[0033] A third elastic member 15 is disposed between the first jaw body 1 and the second jaw body 12 on the other side of the rotating shaft 13, and a pull rope 4 is disposed between the first jaw body 1 and the second jaw body 12 on the side of the temperature measuring device 14 opposite to the third elastic member 15;

[0034] By arranging temperature measuring devices on opposite sides of one end of the rotatably connected first clamp body and second clamp body, personnel can insert the cable between the two temperature measuring devices. When the cable rotates close to the first clamp body and the second clamp body, the pull rope will pull the first clamp body and the second clamp body closer to each other, so that the third elastic member is extended, and the first clamp body and the second clamp body clamp the cable, which is beneficial to reduce the operating force of personnel, reduces the labor intensity of personnel, reduces the situation of personnel losing strength, and improves the reliability of measurement results.

[0035] The first clamp body 1 and the second clamp body 12 are each provided with a plurality of limiting holes 52 along their length direction, and a movable plate 53 is slidably connected inside one end of the first clamp body 1 and the second clamp body 12 away from the temperature measuring device 14, and the movable plate 53 is elastically connected with a limiting block 54 matched with the limiting hole 52;

[0036] By cooperating with the limit block elastically connected by the movable plate and the limit hole, the power arms of the first clamp body and the second clamp body can be extended, reducing the requirements on the hand-holding force of personnel and reducing the situation where personnel hold the heavy load for a long time and cause the force to fall off and affect the measurement, which is conducive to improving the reliability of the measurement.

[0037] The movable plate 53 is provided with a receiving groove 55 , the limiting block 54 is slidably installed inside the receiving groove 55 , and a second elastic member 51 is disposed between the inner wall of the receiving groove 55 and the limiting block 54 .

[0038] A plurality of first elastic members 2 are respectively disposed between the temperature measuring device 14 and the first clamp body 1 and the second clamp body 12 .

[0039] A first magnet 3 is disposed between the rotating shaft 13 and the temperature measuring device 14 and on the first pliers 1, and a second magnet 31 matching the first magnet 3 is disposed on the second pliers 12;

[0040] The magnetic attraction between the first magnet and the second magnet reduces the chance of the first clamp body and the second clamp body bouncing away from each other when the third elastic member is too elastic, increases the clamping force of the measuring device when clamping the cable, and further increases the stability of the measurement by the measuring device.

[0041] A sliding hole 11 is formed in the middle of the first pliers body 1, and the rotating shaft 13 is arranged inside the sliding hole 11, and the middle of the second pliers body 12 is located inside the sliding hole 11 and sleeved on the rotating shaft 13;

[0042] By providing a rotating shaft, the measuring device fits more closely to the cable surface when the first clamp body and the second clamp body are held and force is applied, thereby improving the measuring effect of the measuring device 14 on the cable and the stability during measurement. By providing a sliding hole, the opening angle of the first clamp body and the second clamp body is increased when facing cables of different sizes.

[0043] The first elastic members 2 are arranged at equal intervals along the length direction of the temperature measuring device 14 .

[0044] The working principle is:

[0045] During operation, when it is necessary to detect the temperature of the power cable, the staff will hold the first clamp body and the second clamp body with their palms, and apply force with their palms. When the force is greater than the elasticity of the third elastic member between the first clamp body and the second clamp body, the first clamp body and the second clamp body will rotate around the rotating shaft inside the sliding hole, so that the first clamp body and the second clamp body are close to each other, and then the measuring devices on the first clamp body and the second clamp body are attached to the surface of the cable. The first elastic member on the side wall of the measuring device will make the measuring device fit closely to the surface of the cable, and the elastic force of the elastic member between the measuring device and the first clamp body and the second clamp body will push the measuring device toward the direction of the cable, and then measure;

[0046] When the first clamp body and the second clamp body are close to each other, the distance between the first magnet and the second magnet will also be close as the first clamp body and the second clamp body are close to each other. At this time, the first magnet and the second magnet will be attracted to each other.

[0047] When the measuring device clamps the cable, the pull rope will first contact the cable. As the measuring device further clamps, the pull rope will fit on the surface of the cable. As the pull rope is pulled, the two ends of the pull rope will pull the ends of the first clamp body and the second clamp body, so that the measuring device fits more closely on the cable surface.

[0048] When the movable plate is adjusted to a suitable length, the accommodating groove is aligned with the limiting hole. At this time, the limit block extends from the accommodating groove under the elastic force of the second elastic member, and the limit block is located in the accommodating groove and the limiting hole, so that the position of the movable block is fixed, which can be used to extend the power arms of the first clamp body and the second clamp body, thereby reducing the requirement on the hand-holding force of the personnel.

[0049] When the above-mentioned cable temperature detection device is used, a temperature measuring device is respectively arranged on the opposite sides of one end of the first clamp body and the second clamp body which are rotatably connected. A person can insert the cable between the two temperature measuring devices. When the cable rotates close to the first clamp body and the second clamp body, the pull rope will pull the first clamp body and the second clamp body close to each other, so that the third elastic member is extended, and the first clamp body and the second clamp body clamp the cable, which is conducive to reducing the operating force of the person, reducing the labor intensity of the person, reducing the situation of the person losing strength, and improving the reliability of the measurement result;

[0050] Furthermore, the limit block elastically connected through the movable plate cooperates with the limit hole to extend the power arm of the first clamp body and the second clamp body, reducing the requirement for the hand-holding force of personnel and reducing the situation where personnel hold the heavy load for a long time and cause the loss of force affecting the measurement, which is beneficial to improving the reliability of the measurement.

[0051] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
