[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) The protective cover made of FRP has won unanimous praise from peers inside and outside the province for its excellent performance and beautiful appearance. The protective cover is made of transparent material, which is convenient for observing the operating status of the winch. While ensuring the normal operation of the winch, it also allows the staff to grasp the real-time status of the winch at any time, and promptly discover and deal with possible problems. This design not only improves the safety of the winch, but also improves work efficiency. The wire rope flaw detector on the protective cover can monitor the damage on the surface of the wire rope. At the same time, the FRP material has excellent tensile strength and wear resistance, which can ensure the stable operation of the winch even in extreme environments. Once an emergency such as wire rope breakage occurs, the winch cover can effectively prevent debris from splashing, thereby perfectly resisting emergencies such as wire rope breakage and protecting the personal safety of the staff.

[0021] (2) By using the universal wheel, the staff can quickly move the protective cover equipped with the hydrological winch. The outer walls on both sides of the bottom plate are set to be inclined surfaces, and the opposite surfaces of the slider are also set to be inclined surfaces. When the inclined surface of the slider slides over the inclined surface of the bottom plate, the top surface of the slider can slide at both ends of the bottom surface of the bottom plate. When the forward and reverse motors are turned off, the vertical plate stops moving immediately. At this time, the bottom surface of the base has been lifted off the ground, and the universal wheels have been completely placed on the ground. Then, by using the universal wheel, the staff can move the protective cover equipped with the hydrological winch. Before the inclined surface of the slider slides on the inclined surface of the bottom plate, the bottom surface of the base is placed on the ground, and the universal wheels are completely lifted off the ground. At this time, the protective cover equipped with the hydrological winch is difficult to move. By setting a simple connection method between the long-axis bolt, the first threaded sleeve and the second threaded sleeve, the disassembly and assembly steps of the fiberglass protective cover body are more convenient and quick, and it is also convenient for the staff to replace, repair or clean the winch body.
