Description

Technical Field

[0001] The utility model relates to the technical field of cable maintenance, in particular to a temperature detection device. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. As an important part of power transmission, the quality of cable use is directly related to the safety of the power system. If the cable is overheated for a long time, it will cause the cable to age faster, and eventually cause the cable to break down, destroying the power supply of the power system and the safety of the surrounding environment. Therefore, in the daily operation and maintenance of power equipment, the detection of the surface temperature of the cable is particularly important, but the existing temperature detection devices are mostly point temperature measuring instruments, which are not conducive to improving the accuracy of cable surface temperature detection. Based on this, the utility model designs a temperature detection device to solve the above problems. Utility Model Content

[0003] The utility model aims to provide a temperature detection device to solve the problem that most of the existing temperature detection devices mentioned above are point temperature measuring instruments, which are not conducive to improving the accuracy of cable surface temperature detection.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A temperature detection device comprises a handle, which is in the shape of a straight rod or a retractable insulating rod. A support frame is welded on the top of the handle, and the support frame is a symmetrical structure. A U-shaped rod is fixed to the top circle of the support frame, and a cylindrical tube is welded on the surface of the U-shaped rod. A lower detection plate is welded on the surface of the cylindrical tube, which is used to detect the temperature within the range from the bottom surface of the tested cable to the horizontal cross-section. The lower detection plate is a downward convex arc plate, which is adapted to the curvature of the bottom of the cable. The inner wall of the lower detection plate is evenly provided with a plurality of planes with threaded holes, and each of the planes is threadedly connected with a temperature measuring component. A motor is installed on the top of the support frame, and the output end of the motor is connected to a main gear that rotates synchronously with the rotating shaft through a rotating shaft. The surface of the main gear is meshed with a gear tube, and the surface of the gear tube is integrally formed with the upper detection plate. The inner wall of the upper detection plate is evenly installed with temperature measuring components through a plane. The upper detection plate is a curved plate and forms an annular cavity with the opposite surface of the lower detection plate for passing the cable under test. During the inspection, the inspector holds the handle to make the lower detection plate face the bottom surface of the cable under test and place it concentrically, start the motor, drive the rotating shaft and the main gear to rotate through the output end of the motor, and drive the gear tube to rotate through the main gear, so as to adjust the upper detection plate and the top surface of the cable under test to be concentrically placed through the gear tube, and form an encircling detection structure for the cable surface through the two detection plates. The temperature of the surface of the cable under test is carried out at multiple points through the temperature measuring components evenly distributed on the detection plate, and the vertical direction is 360° fully covered. Compared with traditional point-type temperature measuring instruments, the range of cable surface temperature detection is improved.

[0006] As a further solution of the utility model: the lower end of the handle is detachably connected with a gripping portion, and a battery compartment is installed on the side of the gripping portion, and the battery compartment is used to power the motor.

[0007] As a further solution of the utility model: the lower half of the detection plate is a semi-cylindrical panel, which is used to adapt to the curvature of the surface of the cable to be tested.

[0008] As a further solution of the utility model: the temperature measuring component is one or a combination of a thermocouple thermometer, an optical thermometer, and a gas thermometer, which can improve the convenience of temperature detection.

[0009] As a further solution of the utility model: an auxiliary connecting block is welded on the top of the support frame, one end of the rotating shaft passes through the auxiliary connecting block, and a bearing is provided at the connecting part of the rotating shaft and the auxiliary connecting block. The auxiliary connecting block can reduce the load on the output end of the motor by supporting one end of the rotating shaft, thereby avoiding the displacement of the use position of the rotating shaft during long-term use.

[0010] As a further solution of the utility model: a cable to be tested coaxially penetrates the annular cavity, and a diameter of the annular cavity is not less than a diameter of the cable to be tested.

[0011] As a further solution of the utility model: a supporting plate adapted to the bottom end of the upper detection plate is welded on the side of the U-shaped rod, which is used to support the bottom of the upper detection plate and improve the stability of the upper detection plate in use.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, by setting a lower detection plate adapted to the curvature of the bottom of the cable under test, it can be used to detect the temperature within the range from the bottom surface to the horizontal cross-section of the cable under test. The orthographic projections of the lower detection plate and the upper detection plate are symmetrical about the bisecting plane of the cable under test, so that the surface of the cable under test can be simultaneously tested in a 360° annular manner, which improves the range of cable surface temperature detection compared with traditional point-type temperature measuring instruments.

[0014] 2. In the utility model, the motor is powered by batteries installed in the battery compartment, which is compact and easy to use.
