[0062] First of all, before introducing this application, let me first introduce the relevant content of this application regarding the application background.

[0063] The water treatment facility with a cut-off mechanism provided in the present application can be applied to a drainage system, and the diversion facility can be a diversion well. A hollow structure is arranged inside the cover body, and a flexible sleeve with a chamber is arranged in the hollow structure, and a water hole is arranged on the cover body. When the flexible sleeve expands, the water hole is closed by the flexible sleeve filling the entire hollow structure during the expansion process. When the flexible sleeve contracts, the water hole is connected by the flexible sleeve not filling the entire hollow structure during the contraction process. Such a structural design does not require the flexible sleeve to be arranged on the outside of the steel outer cover as in the prior art, nor does it require the flexible sleeve to wrap the entire steel outer cover. Instead, it only requires the flexible sleeve to be arranged in the hollow structure of the cover body to achieve the connection or closure of the water hole through expansion or contraction. When it is installed in a diversion facility such as a diversion well, it only needs to be connected to the water outlet pipe therein, and it does not need to be installed horizontally in the well as a whole, and has the characteristic of occupying extremely small space.

[0064] Next, the water treatment facility with a shut-off mechanism provided by the present application will be specifically introduced.

[0065] Embodiment 1

[0066] See also Figure 1-8 The water treatment facility with a cut-off mechanism provided in the embodiment of the present application comprises: a well body 4, a flexible sleeve 12 and a cover body 11. The well body 4 is provided with a water outlet pipe 41, and the flexible sleeve 12 has a chamber 121 for filling a filler; the cover body 11 has a connection port 112 connected to the water outlet pipe, and a hollow structure 113 for the flexible sleeve 12 to expand or contract in the cover body 11, and a plurality of water holes 111 for water circulation are provided on the opposite side of the connection port 112; the flexible sleeve 12 is arranged in the hollow structure 113, and can expand and contract in the hollow structure 113.

[0067] The well body 4 is provided with at least one water outlet pipe 41. It can be understood that the number of the flexible intercepting mechanism 1 in the embodiment of the present application can be one or more, and the number of the water outlet pipes 41 in the well body 4 can also be one or more.

[0068] For example:

[0069] As an implementation method of an embodiment of the present application, the number of flexible intercepting mechanisms 1 is one, and the number of water outlet pipes 41 is one. At this time, the water outlet pipe 41 is connected to a natural water body through a downstream pipe, and the flexible intercepting mechanism 1 is fixed at the pipe mouth of the water outlet pipe 41 to intercept or release the water entering the water outlet pipe 41.

[0070] As another implementation method of the embodiment of the present application, the number of flexible intercepting mechanisms 1 is one, and the number of outlet pipes 41 is two. In this case, one of the outlet pipes 41 can be connected to a natural water body through a downstream pipe, and the other outlet pipe 41 can be connected to a sewage treatment plant or a sewage storage tank through a downstream pipe. The flexible intercepting mechanism 1 is fixed at the pipe mouth of any one of the outlet pipes 41 to intercept or release the water entering the outlet pipe 41.

[0071] As another implementation method of the embodiment of the present application, the number of flexible intercepting mechanisms 1 can be two, and the number of the outlet pipes 41 is two. In this case, one of the outlet pipes 41 can be connected to a natural water body through a downstream pipe, and the other outlet pipe 41 can be connected to a sewage treatment plant or a sewage storage tank through a downstream pipe. Each flexible intercepting mechanism 1 is fixed at the pipe mouth of a corresponding outlet pipe 41.

[0072] Of course, those skilled in the art can understand that the above matching numbers of the flexible intercepting mechanism 1 and the water outlet pipe 41 are only three examples and are not limiting. In other words, the embodiments of matching a plurality of (greater than or equal to 1) water outlet pipes 41 provided in the well body 4 with a plurality of (greater than or equal to 1) flexible intercepting mechanisms 1 are all applicable to the present invention.

[0073] In the embodiment of the present application, the water hole 111 can be understood as a hole for the flow of water or other flowing liquids after the flexible intercepting mechanism is connected to the outlet pipe 41 of the diversion well. The flexible sleeve 12 can be a flexible airbag with contraction and expansion functions, and the expansion of the airbag is achieved by filling the chamber 121 inside the flexible sleeve 12, or the contraction of the airbag is achieved by discharging the filler from the chamber 121 inside the flexible sleeve 12. When the flexible sleeve 12 expands in the hollow structure 113, the expanded flexible sleeve 12 can fill the entire hollow structure 113 and block the water hole 111 to close it, thereby achieving interception; and when the flexible sleeve 12 shrinks in the hollow structure 113, the shrunken flexible sleeve 12 will not fill the entire hollow structure 113, and then will not be able to block the water hole 111, and finally the conduction of the water hole 111 is achieved. Those skilled in the art can understand that such a structural design makes it unnecessary to put the flexible sleeve 12 on the outside of the steel outer cover as in the prior art, nor does it require the flexible sleeve 12 to wrap around the entire steel outer cover. Instead, the flexible sleeve only needs to be set in the hollow structure of the cover body to achieve the opening or closing of the water hole through expansion or contraction. When installing it in the well body 4, it is not necessary to install it entirely horizontally in the well, and it occupies very little space.

[0074] It should be noted that, in the embodiment of the present application, the cover body 11 can be cylindrical, the shape of the flexible sleeve 12 is adapted to the shape of the cover body 11, a through hole 122 is provided at the top of the flexible sleeve 12, and communicated with the chamber 121; wherein, a plurality of water holes 111 are provided on one side of the cover body 11, and a connecting port 112 is provided on the other side opposite to the side, and an external pipeline is connected through the connecting port 112.

[0075] Of course, those skilled in the art can understand that the cylindrical shape of the cover body 11 is only one structural form of the cover body 11 in the embodiment of the present application. In addition to the cylindrical shape, the cover body 11 can also be square, trapezoidal, and other structural forms. Correspondingly, when the structural form of the cover body 11 changes, the shape of the flexible sleeve 12 will also be adjusted and changed accordingly, and the present application is not limited thereto. In other words, the cover body 11 structure that can only achieve the flexible sleeve 12 expansion and deformation to block the water hole 111 and thus achieve the interception state, and the corresponding flexible sleeve 12 structure, can both be applied to the present invention.

[0076] Furthermore, in order to stabilize the installation of the flexible sleeve 12 in the hollow structure 113 of the cover body 11, the embodiment of the present application further includes a first support frame 13 and a first hanging chain 14. The first support frame 13 is fixed to the top of the cover body 11; one end (the upper end shown in the figure) of the first hanging chain 14 is fixed to the first support frame 13, and the other end (the lower end shown in the figure) is connected to the top of the flexible sleeve 12.

[0077] Furthermore, in order to prevent the flexible sleeve 12 from being affected by the buoyancy of water in the hollow structure 113 of the cover body 11, the embodiment of the present application may further include a second support frame 15 and a second hanging chain 16 on the basis of the above. The second support frame 15 is fixed to the bottom of the cover body 11; one end (the lower end shown in the figure) of the second hanging chain 16 is fixed to the second support frame 15, and the other end (the upper end shown in the figure) is connected to the bottom of the flexible sleeve 12; so that when the flexible sleeve 12 is affected by the buoyancy of water, the second support frame 15 and the second hanging chain 16 can form a pulling force on the flexible sleeve 12, further enhancing its temperature in the hollow structure 113. The flexible sleeve 12 is located between the first support frame 13 and the second support frame 15.

[0078] Of course, in order to facilitate the quick installation between the cover body 11 and the water outlet pipe 41, in the embodiment of the present application, the cover body 11 can be a three-way structure, and the connecting port 112 extends outward in the flow direction of the cover body 11, so that it can be bolted to the water outlet pipe 41 through the connecting port 112, or directly inserted into the water outlet pipe 41 and clamped therewith.

[0079] It should be noted that the filler in the embodiment of the present application can be a gas (such as air, nitrogen, inert gas, etc.) or a liquid (such as hydraulic oil, water, etc.). The embodiment of the present application is not limited as an implementation method. When the filler is water, please continue to refer to Figure 6 The embodiment of the present application may further include: a pipeline group, a valve group box 18 and a control box 19.

[0080] The pipeline group is connected to the chamber 121 ; the valve group box 18 is connected to the pipeline group; and the control box 19 is connected to the valve group box 18 and is used to control the on-off of the pipelines in the pipeline group through the valve group box 18 .

[0081] As an implementation of the valve assembly box 18, it may include: valve A181 and valve B182. The valve A181 is connected to the control box 19, and the valve B182 is connected to the control box 19 and connected to the valve A181 through an intermediate pipe.

[0082] As an implementation of the pipeline group, it may include: pipeline A171 and pipeline B172. One pipe opening of pipeline A171 is connected to the chamber 121, and the other pipe opening of pipeline A171 is connected to the middle pipe; one pipe opening of pipeline B172 is connected to valve B182, and the other pipe opening of pipeline B172 is externally connected to the water supply pipeline 3.

[0083] Specifically, when the flexible interception mechanism 1 is required to intercept, the control box 19 can control valve A to close and valve B to open. At this time, the water in the water supply pipe 3 is sequentially filled into the chamber in the flexible sleeve 12 through the pipe B, the intermediate pipe and the pipe A, and then the flexible sleeve 12 begins to expand until the entire hollow structure 113 is filled and the water hole is blocked, thereby forming interception in turn. The control principle of the control box 19 controlling valves A and B is not limited in the embodiment of the present application, and the control principle in the prior art can be adopted.

[0084] As another embodiment, when the filler is air, please continue to refer to Figure 8 , the embodiment of the present application also includes: pipeline C173, valve C183 and air compressor 194. Among them, pipeline C173 is connected to the flexible sleeve 12; valve C is connected to pipeline C; air compressor 194 is connected to valve C, and is used to control the inflation or deflation of the flexible sleeve 12 through valve C183. Similarly, the control principle of the air compressor 194 controlling the valve C is not limited in the embodiment of the present application, and the control principle in the prior art can be adopted.

[0085] Furthermore, the embodiment of the present application further includes: a support rod 191 and a solar panel 192. The support rod 191 is fixed on the ground, the valve assembly box 18 is fixed to the lower position of the support rod 191, the air compressor 194 or the control box 19 is fixed to the upper position of the support rod 191, and the solar panel 192 is fixed to the upper position of the support rod 191 and connected to the control box 19 or the air compressor 194. In this way, the support rod 191 provides support for the installation of the valve assembly box 18, the control box 19 or the air compressor 194, and the solar panel 192.

[0086] Of course, those skilled in the art will understand that in addition to converting solar energy through the solar panel 192 to power the control box 19 and the valve group box 18 in the embodiment of the present application, the control box 19 and / or the valve group box 18 can also be powered by directly connecting the control box 19 and / or the valve group box 18 to an external power source, and the embodiment of the present application is not limited to this. In other words, the control box 19 or the air compressor 194, and / or the valve group box 18 can also be powered by directly connecting the control box 19 or the air compressor 194, and / or the valve group box 18 to an external power source. The power supply is also applicable to the present invention.

[0087] In the embodiment of the present application, the cover body 11 can be fixed to the well wall of the well body 4 by means of anchor bolt connection, for example, a plurality of pressure strips 193 can be used to fix the cover body 11 to the well wall by means of anchor bolts. Of course, the connection method between the cover body 11 and the well wall can also be other methods such as flange connection and bolt connection, and the present invention is not limited thereto. As long as the connection method can realize the fixing of the cover body 11 to the well wall of the well body 4, it is applicable to the present invention.

[0088] In summary, the water treatment facility with a shut-off mechanism provided in the embodiment of the present application is achieved by setting a hollow structure inside the cover body, and setting a flexible sleeve with a chamber inside the hollow structure, and a water hole is provided on the cover body. When the flexible sleeve expands, the water hole is closed by the flexible sleeve filling the entire hollow structure during the expansion process, and when the flexible sleeve contracts, the water hole is connected by the flexible sleeve not filling the entire hollow structure during the contraction process. Such a structural design does not require the flexible sleeve to be set on the outside of the steel outer cover as in the prior art, nor does it require the flexible sleeve to wrap the entire steel outer cover. Instead, it only requires the flexible sleeve to be set in the hollow structure of the cover body to achieve the connection or closure of the water hole through expansion or contraction. When the flexible shut-off mechanism is installed in the well body, it is not necessary to install it entirely horizontally in the well, and it has the characteristic of occupying extremely small space.

[0089] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
