[0007] An internal thread is arranged on the inner side of the top end of the insertion hole, and a stop bolt made of plastic material is installed inside the insertion hole, and the end of the stop bolt abuts against the upper end of the connecting rod inside the insertion hole.

[0008] The water tank base has a base body, the top of the base body has a support part, the top of the base body is provided with a mounting groove corresponding to one side of the support part, the mounting groove matches the bottom end of the support rod, and the support rod is detachably fixedly connected to the support part.

[0009] A slot is provided at the lower end of the support rod, a stud matching the slot is provided at one side of the support portion, and a fixing nut is mounted on the stud.

[0010] A water filling cover is arranged on the top of the support part, and a drainage cover is arranged on one side of the bottom of the base body.

[0011] The support portion is a right-angled triangular protrusion structure that is integrated with the base body, and the support portion is communicated with the base body.

[0012] The flexible flat belt is a nylon flat belt.

[0013] Beneficial effects of the utility model:

[0014] (1) In the utility model, after the water tank base is filled with seawater, it is placed at the edge of the platform. The lower end of the support rod is installed on the water tank base to support the support rod. A retractable protective net assembly is arranged between two adjacent support rods. The retractable protective net assembly protects the personnel on the platform and reduces the risk of personnel falling into the sea when approaching the edge.
