Problems solved by technology
[0002] In the process of cable installation, it is usually necessary to install a temperature monitoring device in the cable to prevent the cable from overheating during operation, so that the staff can control the temperature of the cable to avoid short circuits caused by high temperature cables or aging wires , or even cause a fire in serious cases, the existing temperature online monitoring device is generally connected to the control equipment by the temperature monitoring port, and the temperature in the cable tunnel is measured by the temperature monitoring port, and then transmitted to the device by the circuit for further monitoring. It is shown that the staff can get the temperature of the cable in each section, and the temperature monitoring port is set inside the middle joint, and the cable is placed on the ground and it is easy to be stained with sand. When the cable is moved to the middle joint, the cable will Friction with the temperature detection port causes the temperature detection port to fall off or even be damaged

Embodiment
[0017] see Figure 1-Figure 4 , the present invention provides a cable bridge cable tunnel intermediate joint temperature online monitoring device, the structure of which includes a bridge 1, a cable tunnel pipe 2, and an intermediate joint 3. An intermediate joint 3 is connected between the cable tunnel pipes 2, and the intermediate joint 3 includes an intermediate frame body 31, an interlayer frame 32, a placement groove 33, and a temperature detection head 34. The width of the intermediate frame body 31 extends from both ends to the middle. Gradually shrinking, and both sides are connected to the cable tunnel pipe 2, the interlayer frame 32 is embedded in the middle of the middle frame body 31, the placement groove 33 is located at the side end of the interlayer frame 32, and the temperature detection head 34 is installed in the inside of placement groove 33.
[0018] The interlayer frame 32 includes a ring frame 321, an engaging block 322, a through groove 323, and an int...

The invention discloses a cable bridge cable tunnel intermediate joint temperature on-line monitoring device which structurally comprises bridges, cable tunnel pipes and an intermediate joint, the number of the bridges is two, the tops of the bridges are connected to the cable tunnel pipes, the intermediate joint is connected between the cable tunnel pipes, and the intermediate joint comprises an intermediate frame body, an interlayer frame, a placing groove and a temperature detection head. The interlayer frame comprises a circular ring frame, a clamping block, a penetrating groove and an intercepting block, the intercepting block comprises an intercepting body, a cutting groove and a protruding block, the temperature detection head is installed in the placing groove, and then the circular ring frame is used for fixing the cable, so that the cable cannot make contact with the end face of the temperature detection head when penetrating through the intermediate frame body, the temperature detection head is prevented from falling off, the temperature of the cable can also be detected, the situation that the temperature of the cable is too high is prevented, and the aging speed of the cable is slowed down.
Description
technical field [0001] The invention relates to the field of cable monitoring, in particular to an on-line temperature monitoring device for the middle joint of a cable bridge and cable tunnel.
