For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] The present invention discloses a floating head assembly and a floating head. The floating head can be used for plugging water outlets of underwater pipelines and can also be used for plugging holes of other structures. There are multiple implementation methods.

[0033] The first implementation method of floating head is as follows Figure 1 The floating head includes a head body 2, a sealing plate 12 and at least two first regulating pipes 3. The sealing plate 12 is sealed and connected with the head body 2 to form a first cavity 11; the first regulating pipe 3 is arranged on the head body 2, one end of which is connected with the first cavity 11 and the other end is placed outside the first cavity.

[0034] With this structure, a sealing plate 12 is provided on the head body 2. The sealing plate 12 is provided on the inner concave surface of the head body 2 and forms a first cavity between the head body 2. Before launching, a first valve is installed at one end of the first regulating pipe 3 outside the first cavity. The first valve is closed to seal the first cavity. Since the cavity has a certain buoyancy, the weight of the floating head as a whole can be reduced during underwater operations, which is convenient for underwater construction. When it is necessary to control the sinking of the floating head, the first valve 71 is opened and water is injected into the first cavity to achieve sinking control.

[0035] During the floating control, at least one first regulating tube 3 is connected to the drainage tube, and at least one first regulating tube 3 is connected to the inflation tube to discharge the water in the first cavity 11 and realize floating.

[0036] In order to facilitate the flattening process when removing the plug after plugging, at least one second regulating pipe 4 can be provided, and the second regulating pipe 4 passes through the plug body 2 and the sealing plate 12 at the same time. Before launching, a second valve 72 is installed at one end of the second regulating pipe 4 close to the plug body 2. Under the plugging condition, the second valve is closed, and when it needs to be removed, the second valve can be opened.

[0037] In order to enhance the structural stability of the floating head, a reinforcing structure 5 is provided on the sealing plate 12. The reinforcing structure 5 includes a shroud connected to the sealing plate 12 and reinforcing ribs connected between the shroud and the bottom plate 1.

[0038] For example, Figure 1 As shown, two first adjusting tubes 3 and two second adjusting tubes 4 are arranged on the head body 2 .

[0039] The diameter of the first regulating tube 3 is smaller than the diameter of the second regulating tube 4 .

[0040] The second implementation of the floating head is based on the assembly of at least two floating head assemblies, that is, the first implementation is split into at least two floating head assemblies. This structure can not only reduce the weight of the head, but also reduce the volume of a single head assembly, making it easier to use in scenarios where the on-site environment is limited and large mechanical equipment cannot be used.

[0041] Structural reference of floating head assembly Figure 2 , 3 , including a bottom plate 1, a head body 2, a sealing connection plate 6 and at least two first regulating tubes 3. Among them, the bottom plate 1 is placed on one side of the inner concave surface of the head body 2, and has an opening structure between the head body 2, that is, except for the opening structure, the connection between the head body 2 and the bottom plate 1 is a sealed connection. The sealing connection plate 6 is used to seal the opening structure formed by the head body 2 and the bottom plate 1 so that a second cavity 61 is formed between the head body 2, the bottom plate 1 and the sealing connection plate 6. The sealing connection plate 6 is provided with connecting holes 62 for connecting two adjacent floating head assemblies around it. The first regulating tube 3 is arranged on the head body 2, and one end is connected to the second cavity 61, and the other end is placed outside the second cavity 61.

[0042] The shape of the sealing connecting plate 6 is determined according to the number of floating head assemblies that constitute the floating head. For example, if two floating head assemblies can be assembled into a floating head, the sealing connecting plate 6 is in a sheet shape; if the floating head requires more than or equal to 3 floating head assemblies to be assembled, the sealing connecting plate 6 is in an L shape.

[0043] In order to facilitate the flattening process when removing the plug after plugging is completed, at least one second adjusting tube 4 is also included, and the second adjusting tube 4 passes through the plug body 2 and the bottom plate 1 at the same time.

[0044] In order to improve the structural stability of the floating head assembly, a reinforcement structure 5 is provided on the bottom. The reinforcement structure 5 includes a shroud connected to the bottom plate 1 and reinforcement ribs connected between the shroud and the bottom plate 1 .

[0045] In order to improve the sealing performance of the assembly of the two floating head assemblies, the connection holes 62 are evenly distributed around the sealing connection plate 6 .

[0046] The floating head assembled by the above floating head assembly is shown in Figure 4 , comprising at least two floating head assemblies of any one of the above structures. The sealing connecting plates 6 of two adjacent floating head assemblies are fixedly connected by bolts 8.

[0047] Among them, the two floating head assemblies can have the same structure, such as Figure 4 As shown, after the assembly is completed, a complete floating head is formed.

[0048] Of course, the structures of the two floating head assemblies may also be different. For example, a second adjusting tube 4 is provided on one floating head assembly, while the second adjusting tube 4 is not provided on the other floating head assembly. For another example, the head bodies 2 and bottom plates 1 of the two floating head assemblies are different in size, that is, the head bodies 2 may not both be half of the desired ellipse, but one may be one-third and the other two-thirds, as long as the two head bodies 2 are spliced ​​into the desired ellipse.

[0049] This structure is the same as the first method. Before launching, a first valve 71 is installed at one end of the first regulating tube 3 outside the second cavity, and the first valve is closed to seal the second cavity; and a second valve 72 is installed at one end of the second regulating tube 4 close to the head body 2, and the first valve is closed. After launching, since the second cavity is sealed, its buoyancy can reduce the overall weight of the floating head, which is convenient for underwater construction. When it is necessary to control the sinking of the floating head, open the first valve 71, inject water into the second cavity, and the sinking control can be achieved. When it is necessary to remove the floating head, open the second valve.

[0050] A sealing pad is arranged between the sealing connecting plates 6 of the two floating head assemblies. In order to further improve the sealing performance, a sealing ring can be arranged around the bottom plate 1.

[0051] The first valve 71 and the second valve may be ball valves or other valve structures.

[0052] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
