Description

Technical Field

[0001] The utility model belongs to the technical field of underwater plugging, and in particular relates to a plugging plate structure for plugging an underwater hole. Background Art

[0002] Underwater plugging is a method of plugging the target pipeline underwater using plates. With the rapid development of society and the continuous improvement of plugging technology, underwater plugging technology has been widely used.

[0003] The main structure of the plugging plate depends on the size of the plugged pipe opening and the pressure. It is generally welded with 10mm thick steel plates, channel steels and angle steels. For example, China Utility Model Patent Authorization Announcement No. CN216517919U discloses a plugging plate structure for underwater plugging. By providing expansion screws, positioning steel bars, cotton rings and rubber pads, a better plugging effect is achieved. Five groups of positioning steel bars are distributed in a ring shape on one side of the circular steel plate, which can fit on the inner wall of the pipe to prevent the circular steel plate from shifting and quickly position the circular steel plate. The distribution of the expansion screws facilitates the firm installation of the circular steel plate. At the same time, the setting of the cotton ring and the rubber pad will be deformed under the action of the extrusion force and fill the gap between the circular steel plate and the wall, thereby improving the plugging effect of the plugging plate structure; by providing the first The equalizing pipe, the second equalizing pipe and the control valve realize the regulation of the pressure on both sides of the sealing plate. The first equalizing pipe and the second equalizing pipe are arranged in parallel, and the first equalizing pipe is higher than the second equalizing pipe. When sealing, the control valve can be operated to connect the water flow on both sides of the circular steel plate, and the water pressure difference on both sides can be reduced by the flow of water to avoid the influence of water pressure on the installation, so that the sealing plate structure has a pressure stabilizing function; by providing an attachment groove, an anti-corrosion coating and an outer covering layer, the anti-corrosion of the sealing plate structure is achieved. The anti-corrosion coating is evenly covered on the outer wall of the circular steel plate to form a protective layer, which can effectively block the direct contact between media such as water and oxygen and the circular steel plate, prevent the circular steel plate from corrosion, and the setting of the attachment groove can prevent the anti-corrosion coating from falling off, thereby extending the service life of the sealing plate structure.

[0004] Although the above-mentioned prior art can make the pressure inside the pipeline consistent with the underwater pressure through the pressure stabilizing structure for easy installation, due to the limitation of the pipe diameter and the size of the sealing plate, the operator encounters great resistance when pushing the sealing plate into the hole underwater, making the installation extremely inconvenient.

The present invention provides the following embodiments.

[0029] like Figure 1 as well as Figure 2 As shown, it is a schematic diagram of a sealing plate structure for sealing an underwater hole in a preferred embodiment of the utility model. The sealing plate structure for sealing an underwater hole in this embodiment includes a sealing outer plate 100. The sealing outer plate 100 is hollow inside and has a plurality of penetrating water grooves 101 on the outside. The sealing outer plate 100 on one side of each water groove 101 is rotatably connected to a sealing inner plate 200. The plurality of water grooves 101 allow the operator to move the sealing outer plate 100 underwater while water flows through the water grooves 101, thereby reducing resistance, making movement more convenient, and also more convenient installation.

[0030] like Figure 1 As shown, a plurality of expansion screws 102 pass through the sealing outer plate 100, and the plurality of expansion screws 102 are connected to the wall inside the opening. A plurality of positioning steel bars 103 inserted into the opening for positioning are fixedly connected to the back of the sealing outer plate 100. When sealing the opening, the plurality of positioning steel bars 103 are inserted into the opening for positioning, and then the plurality of expansion screws 102 are connected to the inner wall of the opening to fix the sealing outer plate 100. Then, the plurality of sealing inner plates 200 are rotated to block the water groove 101 to complete the sealing. The outer wall edge of the sealing outer plate 100 is chamfered, and the edge of each water groove 101 close to the outside is chamfered, so as to reduce the resistance when moving in water.

[0031] like Figure 2 as well as Figure 3As shown, it is a schematic diagram of the cross-section of the sealing outer plate and the front view of the sealing inner plate in this embodiment, a connecting plate 201 fixedly connected to each sealing inner plate 200 is arranged at the center of the multiple connecting plates 201, a through hole is arranged on the front side of the sealing outer plate 100, and a hexagon socket head 208 passing through the through hole is fixedly connected to the front side of the sealing inner plate 200.

In this embodiment, when the blocking inner plate 200 is retracted inside the blocking outer plate 100, the sealing plug plate 206 is retracted inside the blocking inner plate 200. When the blocking inner plate 200 is rotated and moved until the outer wall of the blocking inner plate 200 which is close to the rotation direction is inserted into the inner wall of the blocking outer plate 100 on the other side, the first connecting groove 202 is exposed to the outside, so that water enters the inside of the blocking inner plate 200 to squeeze the filling plate 205 toward the back side of the blocking inner plate 200, thereby making the sealing plug plate 206 extend and insert into the inside of the limiting groove 105, thereby making the sealing better.

[0033] like Figure 4 As shown, in order to further reduce the resistance of the blocking outer plate 100 when it moves in the water, in this embodiment, a cone head 204 is fixedly connected to the center of the back side of the blocking outer plate 100.
