Preferably, the camera 1 is an infrared night camera; the camera 1 is connected to the control system circuit; a limit component 2, which is fixedly arranged on the cableway, and the limit component 2 mainly limits the traveling frame 45 and the lead fish; the cableway includes a main cable 42 and a working cable 43; a power supply component 3, which is fixedly arranged in the central control room on the shore; the power supply component 3 is connected to the cableway current measurement system circuit. In addition, it should be noted that the cableway flow measurement system belongs to the existing technology. The connection method between the camera and the control system, as well as the specific model of the camera involved are not the improvement points of this application and will not be elaborated here.

[0031] like Figure 1 and Figure 2 As shown, the limit assembly 2 includes a first limit block 21; the first limit block 21 is arranged at one end of the working rope 43 close to the lead fish; the first limit block 21 is located between the traveling frame 44 and the lead fish; the width of the groove wheel 45 is smaller than the width of the first limit block 21, and preferably, the first limit block 21 is a rectangular structure.

The control system executes the stop flow measurement signal and controls the winch. The winch pulls the working rope 43 to lift the lead fish in the river and raise it to a safe height to avoid endangering the safety of the lead fish from people and animals or large floating objects. If the control system fails and the winch cannot be stopped, the working rope 43 is continuously pulled back, so that the first limit block 21 approaches the traveling frame 44, and the first limit block 21 contacts the groove wheel 45 at the bottom of the traveling frame 44. The first limit block 21 blocks the groove wheel 45, preventing the working rope 43 from being pulled back, preventing the lead fish from continuing to move and colliding with the traveling frame 44, thereby avoiding damage to the lead fish.

If the control system fails and the winch cannot stop, the vertical end of the L-shaped plate 24 contacts the shore column 41, supports the shore column 41, and stops the traveling frame 44 from continuing to move, preventing the traveling frame 44 from colliding with the shore column 41, and avoiding damage to the traveling frame 44.

[0042] like Figure 3 As shown, preferably, the limit assembly 2 also includes a second limit switch 25; the second limit switch 25 is arranged on the shore column 41; the second limit switch 25 is close to the main rope, and its triggering part is located on the same straight line as the L-shaped plate 24; preferably, the second limit switch 25 is a universal limit switch with a steel wire soft rod.
