[0028] Further, if Figure 2 As shown, the shell 1 is provided with a first through hole 7, and the piston passes through the first through hole 7 and is slidably arranged in the shell 1; the piston includes a vertical rod 8 and a push plate 9, the push plate 9 is provided with the vertical rod 8, the vertical rod 8 is slidably arranged in the first through hole 7, and the vertical rod 8 pushes the push plate 9 so that the push plate 9 is slidably arranged in the shell 1; the cover plate at one end of the shell 2 away from the first through hole 7 is provided with a plurality of openings 12, and the cover plate at one end of the shell 1 is provided with a plurality of openings 12 and is connected to the sponge 6, so that the activator can be injected into the sponge 6 through the plurality of openings 12.

[0029] In this embodiment, the shell 1 is preferably a cylinder, and a cover plate at one end of the shell 1 is provided with a first through hole 7, and a vertical rod 8 is vertically arranged on a push plate 9. The push plate 9 is circular, and the vertical rod 8 passes through the first through hole 7 to push the push plate 9 to slide in the shell 1. The cover plate at one end of the shell 1 away from the first through hole 7 is a convex cover plate, and a plurality of evenly distributed openings 12 are provided on the top and around the convex cover plate. The convex cover plate is embedded and bonded with the concave sponge 6, and the push plate 9 pushes the activator in the shell 1 to flow into the sponge 6 through the plurality of openings 12, so that the sponge 6 fully infiltrated with the activator coats the surface of the sea pipe.

[0030] Further, if Figure 1 As shown, the end of the vertical rod 8 away from the push plate 9 is sleeved with the sliding rod 3, and the end of the sliding rod 3 away from the vertical rod 8 is provided with a protrusion 10, so that the protrusion 10 is engaged with the slide groove 2; the sliding rod 3 is provided with a second handle 5, and the second handle 5 is rotated to engage or separate the protrusion 10 with the slide groove 2; the end of the shell 1 away from the first through hole 7 is connected with a cover 11, and the end of the shell 1 connected with the cover 11 is provided with an outer thread, and the outer thread is screwed with the inner thread of the cover 11, so that the sponge 6 is sealed in the cover 11.

[0031] The end of the shell 1 connected to the sponge 6 is provided with a cover 11, which is screwed to the shell 1. In the initial state, the shell 1 is full of activator, and the cover 11 seals the sponge 6 in the cover 11, so that the activator does not contact with seawater, thereby diluting the activator; when in use, the cover 11 is unscrewed, so that the activator flows into the sponge 6, and the activator is coated on the surface of the sea pipe through the sponge 6, thereby improving the efficiency of activator coating and reducing waste.

[0032] Further, if Figure 1 As shown, the housing 1 is provided with a first through hole 7 and a plurality of small holes are opened at one end, and seawater flows into the housing 1 through the plurality of small holes to balance the pressure inside and outside the housing 1; the slide 2 includes a plurality of parallel notches, and the plurality of parallel notches are evenly arranged along the length direction of the surface of the housing 1, so that the protrusions 10 are respectively engaged with or separated from the plurality of parallel notches; the slide bar 3 is L-shaped and sleeved on the vertical rod 8.

When the activator is continued to be used, the second handle 5 is rotated in the opposite direction to separate the protrusion 10 from the corresponding notch. The slide bar 3 is L-shaped and matches the shell 1, which facilitates the rotation of the slide bar 3 and the movement along the activator direction.

[0034] The working principle of the underwater coating device in the utility model is as follows:

[0035] The housing 1 is filled with the activator and the sponge 6 is soaked. The diver grabs the first handle 4 provided on the housing 1 with one hand and presses the second handle 5 with the other hand to make the activator flow into the sponge 6; the second handle 5 is rotated to rotate the slide bar 3 connected to the second handle 5, and the protrusion 10 on the slide bar 3 is engaged with the slide groove 2 on the housing 1 to prevent the vertical rod 8 connected to the slide bar 3 from continuing to push the push plate 9, so that the activator stops flowing into the sponge 6; when continuing to use, the second handle 5 is rotated in the opposite direction to separate the protrusion 10 from the slide groove 2, so that the activator can continue to be pushed into the sponge 6.
