Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

As shown in fig. 1 and 2, the ecological wetland gate control device based on mountain and flood ditches comprises a retaining wall 2 arranged between a river and a wetland system 1 and a floating body box 4 floatingly arranged in the river, wherein a water inlet hole is formed in the lower part of the retaining wall 2, a water inlet 8 is formed in the upper part of the floating body box 4, the bottom of the floating body box 4 is connected with the water inlet hole through a pipeline 3, and the elevation of the bottom of the water inlet 8 of the floating body box 4 is lower than the water level of the river.

Specifically, the retaining wall 2 separates the river from the wetland system 1, so that water in the river cannot directly flow into the wetland system 1, the top elevation of the retaining wall 2 needs to be higher than the highest water level of the river history, the floating body box 4 can be lifted along with the lifting of the river water level, the height difference between the bottom elevation of the water inlet 8 of the floating body box 4 and the river water level is always kept unchanged, the floating body box 4 is in sealing connection with the pipeline 3, and the pipeline 3 is in sealing connection with the water inlet of the retaining wall 2.

It can be understood that, because the bottom elevation of the water inlet 8 of the floating body tank 4 is lower than the river water level, and the height difference between the bottom elevation of the water inlet 8 of the floating body tank 4 and the river water level is always kept unchanged, water in the water flow can always enter the wetland system 1 through the floating body tank 4, the pipeline 3 and the water inlet hole at a fixed flow rate, so that the water entering the wetland system 1 in unit time cannot excessively cause the collapse of the wetland system 1.

In some embodiments, the water inlet 8 is provided with a slice 5 for controlling the flow of water into the float tank 4.

It will be appreciated that by providing a weir flow plate 5 within the float tank 4, the maximum flow of water into the wetland system 1 can be controlled, ensuring that the wetland system 1 does not collapse due to short floods.

Further, as shown in fig. 3, a support plate is disposed in the floating body tank 4, one end of the support plate is fixed at the bottom of the water inlet 8 of the floating body tank 4, and the weir flow plate 5 is fixed on the support plate.

Further, as shown in fig. 4, the slice plate 5 includes a fixed plate 7 and a moving plate 6 that are vertically disposed, the fixed plate 7 is disposed on the support plate, the moving plate 6 is disposed directly above the fixed plate 7, and the moving plate 6 is vertically slidably connected with the floating body tank 4.

Specifically, fixed plate 7 bottom and backup pad are fixed, and the side is connected with body case 4 lateral wall sealing, fixed plate 7 top elevation is less than river water level, the opening size between movable plate 6 and the fixed plate 7 then is the biggest discharge that can get into wetland system 1, thereby the biggest discharge that gets into wetland system 1 through the lift control of control movable plate 6, has seted up vertical spout on the body case 4 lateral wall, has seted up a plurality of bolt holes on the spout, thereby movable plate 6 accessible bolt fastening is on the bolt hole of different co-altitude control movable plate 6.

Further, a first inclined surface inclined downwards is arranged at the top of the back water side of the fixed plate 7, and a second inclined surface inclined downwards is arranged at the bottom of the front water side of the movable plate 6.

It will be appreciated that when the moving plate 6 is moved to the top of the fixed plate 7, the first and second inclined surfaces may fully engage, preventing water flow into the interior of the float tank 4.

In some embodiments, the float tank 4 is funnel-shaped. Facilitating rapid water flow into the conduit 3 and into the wetland system 1.

The working principle of the ecological wetland gate control device is as follows: under normal conditions, the floating body box 4 floats in a river, water in the river can enter the floating body box 4 from the water inlet 8 of the floating body box 4 and then is converged into the pipeline 3 through the weir flow plate 5, and finally enters the wetland system 1 through the water inlet of the retaining wall 2, and as the floating body box 4 can always rise and fall along with the rise and fall of the river water level, the flow entering the wetland system 1 can always be unchanged, and the collapse of the wetland system 1 is prevented; when flood disasters occur, the water level rises rapidly, water flow entering the floating body box 4 in a short time is increased, and water flow entering from the water inlet 8 of the floating body box 4 cannot completely enter the wetland system 1 because the opening between the fixed plate 7 and the movable plate 6 is fixed in size, so that the stability of the wetland system 1 is ensured, and in addition, the movable plate 6 can be moved downwards, so that the first inclined plane and the second inclined plane are completely attached, and water flow is prevented from entering the floating body box 4.

The above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present application, and are intended to be included in the scope of the present application.
