The lock cover 36 protects the internal structure of the lock 3, and guarantees the safety and stability of use. The limiting nut 37 limits the lower end of the rotating shaft 34 below the cover body support 1, so that it cannot come out of the through hole 361.

[0033] As shown in the figures, Figure 2 The cover plate 2 comprises a stainless steel plate 21 at the upper portion and a buoyancy block 22 at the lower portion, the size of the stainless steel plate 21 is larger than that of the buoyancy block 22, the thickness of the stainless steel plate 21 is smaller than that of the buoyancy block 22, and the buoyancy block 22 is fixedly connected with the stainless steel plate 21 through bolts. The function of the buoyancy block 22 is to enhance the buoyancy of water, so that the cover plate 2 can be quickly closed. The material of the buoyancy block 22 can be selected from the materials known in the art. The stainless steel plate 21 provides support for the buoyancy block 22, and does not need to be too thick.

[0034] As shown in the figures, Figure 2 、 Figure 3 and Figure 5 The lower surface of the cover body support 1 is provided with a sealing rubber strip 15 around the outer periphery. The sealing rubber strip 15 makes the cover body support 1 and the barrel body in sealing contact, so as to prevent water from spilling out.

[0035] As shown in the figures, Figure 7 and Figure 11 The outer periphery of the cover body support 1 is evenly provided with a ring buckle avoiding opening 16. The setting of the ring buckle avoiding opening 16 does not affect the installation of the water bag.
