In the following, a water treatment facility with a shut-off mechanism provided by the present application will be described in detail.

Example one

Referring to fig. 1 to 10, a water treatment facility provided by an embodiment of the present application includes: a facility body 4 and at least one shut-off mechanism 5, wherein the facility body 4 is provided with a water inlet pipe 41 and at least one water outlet pipe 42. It is understood that the number of the shut-off mechanism 5 in the embodiment of the present application may be 1 or more, and the number of the water outlet pipe 42 in the facility body 4 may also be 1 or more.

As an implementation manner of the embodiment of the present application, the number of the interception mechanism 5 is one, the number of the water outlet pipe 42 is one, at this time, the water outlet pipe 42 is connected to the natural water body through a downstream pipeline, and the interception mechanism 5 is fixed at a pipe orifice portion of the water outlet pipe 42 to intercept or release water entering the water outlet pipe 42.

As another implementation manner of the embodiment of the present application, the number of the intercepting mechanism 1 is one, the number of the water outlet pipes 42 is two, in this case, one of the water outlet pipes 42 may be connected to the natural water body through a downstream pipeline, the other water outlet pipe 42 may be connected to a sewage treatment plant or a sewage storage tank through a downstream pipeline, and the intercepting mechanism 5 is fixed at a pipe orifice portion of any one of the water outlet pipes 42 to intercept or release water entering the water outlet pipe 42.

As another implementation manner of the embodiment of the present application, the number of the intercepting mechanism 5 may be two, the number of the water outlet pipes 42 is two, at this time, one of the water outlet pipes 42 may be connected to the natural water body through a downstream pipeline, the other water outlet pipe 42 may be connected to a sewage treatment plant or a sewage storage tank through a downstream pipeline, and each intercepting mechanism 5 is fixed at the pipe orifice position of the corresponding one of the water outlet pipes 42.

Of course, it will be understood by those skilled in the art that the above matching numbers for the shut-off mechanism 5 and the outlet pipe 42 are merely three examples, and are not limiting. In other words, a plurality of (greater than or equal to 1) outlet pipes 42 arranged in the facility body 4 are matched with a plurality of (greater than or equal to 1) embodiments of the closure mechanism 5, and the present invention is applicable to both of them.

As for the shut-off mechanism 5, it may comprise: outer barrel 1, drive assembly 2 and seal receptacle 3. Wherein, the first part 11 of the outer cylinder 1 is provided with a first opening 111 for connecting the water inlet pipe 41 or the water outlet pipe 42, and the second part 12 is provided with a second opening 121 for intercepting the flow; the outer cylinder 1 is also provided with a closure seal 14 at said second portion 12; the driving assembly 2 is fixed at a third part 13 of the outer cylinder 1 and is in sealing connection with the third part 13, and the third part 13 and the first part 11 are oppositely distributed on the outer cylinder 1; the sealing seat 3 is fixedly connected with the driving assembly 2, and the first part 11 is positioned between the second part 12 and the third part 13.

In the embodiment of the present application, the first portion 11 may be a side portion of the outer cylinder 1, the second portion 12 may be a bottom portion of the outer cylinder 1, and the third portion 13 may be a top portion of the outer cylinder 1, such that the first portion 11 is located between the second portion 12 and the third portion 13, it can be understood that when the first opening 111 at the first portion 11 is connected to the water outlet pipe 42, a top height of the water outlet pipe 42 is lower than a height of the third portion 13 of the outer cylinder 1, and a bottom height of the water outlet pipe 42 is higher than a height of the second portion 12 of the outer cylinder 1. The inner space of the outer cylinder 1 is a hollow chamber and is used for accommodating the driving component 2, the driving component 2 is a component for driving the sealing element to displace, when the closure is required, the driving component 2 drives the sealing seat 3 to move in the axial direction (namely in the vertical direction shown in the figure) of the first part 11 and the third part 13 so as to be attached to the closure sealing element 14 arranged at the second part 12 to realize the closure, so that the liquid (rainwater, sewage, the mixed water of the rainwater and the sewage and the like) outside the outer cylinder 1 cannot flow into the inner part of the outer cylinder 1 through the second opening 121; or the driving assembly 2 drives the sealing seat 3 to move in the axial direction (i.e. in the vertical direction shown in the figure) of the first portion 11 and the third portion 13 to separate from the intercepting sealing member 14 to achieve conduction, so that liquid (rainwater, sewage, mixed water of rainwater and sewage, etc.) outside the outer cylinder 1 flows into the inner portion of the outer cylinder 1 through the second opening 121 and flows into the water outlet pipe 42 through the first opening 111. It can be seen that, with such a structural design, it is not necessary to arrange a flexible sleeve outside the steel casing as in the prior art, nor to envelop the entire steel casing, but only the driving assembly 2 is fixed at the third portion 13 of the outer cylinder 1 to drive the sealing seat 3 to move in the axial direction of the first portion 11 and the third portion 13, so as to achieve the interception or conduction, and the size of the interception mechanism itself is greatly reduced, and when the interception mechanism is applied to a drainage system (such as a diversion well, an installation well, etc.), it is not necessary to transversely install the entire interception mechanism in the well, and the occupied space is extremely small.

As a first embodiment of the driving assembly 2 in the embodiment of the present application, please continue to refer to fig. 1, the driving assembly 2 may include a first housing 21 and a cylinder 22. The first cover 21 is fixed at the third portion 13 and is connected with the third portion 13 in a sealing manner, and the height of the connection between the first cover 21 and the third portion 13 is higher than the opening height of the first opening 111 at the first portion 11; the cylinder 22 is fixed in the first cover 21 and externally connected with an air compressor, and an output shaft 221 of the cylinder 22 penetrates through the inner space of the outer cylinder 1 and is fixedly connected with the sealing seat 3.
