Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Please refer to Figure 1-Figure 3 The enclosure device for underwater operation provided by the present invention comprises a casing 1 and an annular sealing pad 2, wherein the casing 1 is a cylindrical structure, which is evenly stressed in all directions in the water and is not prone to instability. The annular sealing pad 2 is made of rubber material, and comprises an annular bottom plate 201 and an annular extension 202 vertically arranged on the annular bottom plate 201. A vertical annular groove 2021 is provided on the top of the annular extension 202. The bottom opening of the casing 1 is inserted downward into the annular groove 2021. The height between the bottom of the annular groove 2021 and the bottom of the annular bottom plate 201 is less than the thickness of the annular bottom plate 201, which can ensure that the thinner sealing pad directly below the casing 1 is in close contact with the bottom of the water, and the thicker sealing pads on both sides will not bend, thereby avoiding seepage. In this embodiment, the height from the bottom of the annular groove 2021 to the bottom of the annular bottom plate 201 is half the thickness of the annular bottom plate 201, the thickness of the annular bottom plate 201 is 60 mm, and the height from the bottom of the annular groove 2021 to the bottom of the annular bottom plate 201 is 30 mm.

[0027] In this embodiment, in order to better realize the present invention, the cross-section of the annular bottom plate 201 is a conical structure, and the annular extension portion 202 is vertically arranged on the conical top of the annular bottom plate 201. The shape of the conical structure not only makes the annular bottom plate 201 have a larger bottom area, but also when the bottom of the casing 1 is inserted into the annular groove 2021, the cross-section of the annular sealing gasket 2 on both sides of the annular groove 2021 is a triangular shape, and the bottom length of the triangle can reach 290 mm, and it still has excellent supporting performance, so that the casing 1 and the annular sealing gasket 2 have a more solid supporting performance after cooperation, and provide a stronger support strength for the enclosure device for underwater operations.

[0028] In order to improve the stability and convenience of the connection, the annular extension 202 and the casing 1 are connected by bolts. The bolts are tension bolts 3. The tension bolts 3 are arranged in two rows up and down. The tension bolts 3 have high tensile strength and shear strength, and can withstand large tensile and shear forces to ensure the stability and safety of the connection structure between the casing 1 and the annular sealing gasket 2. And its special fastening method makes the bolts not easy to loosen, which improves the reliability of the connection. The tension bolts 3 have a compact structure, and the installation and disassembly process is relatively simple, which saves a lot of time and labor costs. This convenience makes the tension bolts widely used in various projects, especially in occasions that require frequent disassembly and reassembly.

[0029] In order to better realize the present invention, the above structure is further optimized, and the casing 1 is made of carbon steel. It is low-cost, has high strength and weight, and improves the stability of the casing. When selecting, different casing wall thicknesses are selected according to different engineering requirements, such as the difference in liquid level height in the pool. The wall thickness must be ≥8mm to have a large deadweight so that the annular sealing gasket 2 below is in close contact with the bottom of the water, so that the casing 1 can withstand water pressure, and use its own weight to make the annular sealing gasket 2 at the bottom in close contact with the bottom of the water, thereby improving the sealing performance.

[0030] When in use, the device is placed in a pool or pump pit by hoisting, so that the annular sealing gasket 2 contacts the bottom of the water, and the weight of the casing 1 is used to squeeze the annular groove 2021 downward, so that the thinner sealing gasket below the annular groove 2021 is in close contact with the bottom of the water under gravity, which plays a role of extrusion isolation, and at the same time, the thicker sealing gaskets on both sides will not be warped, and seepage will be avoided, thereby achieving physical isolation of the medium inside and outside the casing 1, and then a pump is placed in the casing 1 to discharge the accumulated water inside, so as to achieve the purpose of emptying the inside of the casing in a short time, and then the waterless space inside can be used to help workers smoothly implement the scheduled engineering tasks such as equipment installation, maintenance, and civil engineering, and at the same time, it is used with a pump during operation, and even if a small amount of water seepage occurs, the accumulated water can be quickly drained by the pump. Moreover, the device can be reused, and after completing the operation, the casing 1 and the annular sealing gasket 2 can be completely taken out, and can still be used next time.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
