Description

Technical Field

[0001] The utility model relates to the technical field of valves, and more specifically, to a valve and a dam for water level control. Background Art

[0002] As an important part of blue-green infrastructure, constructed wetlands have increasingly diverse application scenarios. It can provide diverse ecosystem services, such as purifying water quality for the treatment and regeneration of slightly polluted water bodies; regulating rainwater and flood. In China, in the face of the problems of urban rainwater and flood management, the construction concept and practice system of "sponge city" have been put forward. Constructed wetlands, because they perfectly realize functions such as "storing, retaining, and purifying", are used as important rainwater and flood regulation measures and have a large demand for application; ecological restoration, constructed wetlands can form diverse habitats to provide habitats for wild animals, and are used for the ecological restoration and improvement of natural habitats such as lakes, rivers, and water sources to improve the stability of the ecosystem; landscape and recreation, it can provide opportunities for human recreation activities and ecological environment education. At the same time, compared with other ecological restoration measures, constructed wetlands have relatively low costs and are one of the key measures for preventing non-point source pollution, improving the water quality of urban rivers, and optimizing urban wetland parks.

[0003] Different filter ponds in constructed wetlands are usually separated by dams, and valves are installed on the dams to control the water flow direction and water level. The commonly used types of constructed wetlands are divided into four categories, and their main differences lie in the different operating water level heights and water flow directions. At present, the existing valves can only control the water level by controlling the flow rate. For the situation where the water inflow is unstable or even fluctuates greatly, the water level control is not accurate; and the existing valves are usually single valves installed at the bottom of the water, which is inconvenient to operate; in addition, the existing valves can only release water from the bottom operation, and often cannot be operated from the water surface, which is inconvenient to use, cannot meet different control requirements, and the water level adjustment speed is slow and the efficiency is low. Summary of the Utility Model

[0004] The utility model aims to overcome at least one defect (shortcoming) of the above-mentioned existing technologies, and provides a valve and a dam for water level control to realize selective control of water flow release.

[0005] An object of the utility model is to provide a valve for water level control, comprising:

[0006] A hollow vertical valve body;

[0007] A strip-shaped valve core rotatably arranged in the vertical valve body;

[0008] At least two communication groups vertically distributed are arranged on the strip-shaped valve core, and each communication group comprises a plurality of communication channels;

[0009] The communication groups face different directions;

[0010] The blocking side and the conducting side of the vertical valve body are respectively provided with a water inlet and a water outlet corresponding to the communication channel.

[0011] In this technical solution, the vertical valve body is a structure installed on the dam body, and the communication channel allows water to flow through. The water body enters the communication channel from the water inlet on the blocking side of the vertical valve body and then flows out from the water outlet on the conducting side. In an artificial wetland system, different communication groups correspond to different subsurface flow layers, and the orientations of different communication groups are different, that is, different communication channels have different orientations, so that different communication groups are not conducted simultaneously, realizing the selective on-off control of different subsurface flow layers and the interaction of the subsurface flow layers at the same height on both sides of the valve, meeting different requirements for operations in actual artificial wetlands and adapting to more different situations.

[0012] In addition, when releasing water, the water flow to be released can be selected at the corresponding height according to the requirements of the wetland type to adjust the water level, so as to realize the conversion of different types of wetlands; moreover, since the water level is adjusted without infiltrating from the bottom in this solution, but the water flow is released from the corresponding height, the water level can be adjusted quickly in this way, improving the efficiency.

[0013] Further, the communication group includes at least two communication channels.

[0014] In this technical solution, the setting of multiple communication channels can improve the water passing efficiency and prevent blockage; at the same time, compared with the setting of a single communication channel, multiple communication channels can divide the water flow, reducing the impact of the water flow on the valve body and being beneficial to the maintenance work of the valve body.

[0015] Further, the communication channels are horizontally arranged, and the distances between adjacent two communication channels in the same communication group are equal.

[0016] In this technical solution, the horizontal arrangement of the communication channels facilitates the control of their height and improves the accuracy of height control; the equal distances between adjacent two communication channels make the water flow distribution uniform when the water body flows through this communication group, further reducing the impact of the water body on the valve body, especially when the valve body is opened.

[0017] Further, the heights of the communication channels on the strip-shaped valve core are different, and the communication channels in the same communication group have the same orientation.

[0018] In this technical solution, the different communication channels are distributed in the vertical direction, enabling different heights of the subsurface flow layer to be connected, so that the water body is evenly distributed in the subsurface flow layer; the communication channels in the same communication group have the same orientation, enabling the communication channels in the same communication group to be opened synchronously and increasing the connection speed.

[0019] Further, a separation limiting ring is provided between any two communication groups.

[0020] In the present technical solution, the separating limit ring is used to limit the strip valve core in the vertical valve body and to separate different connecting groups; compared with the strip valve core being limited by itself in the vertical valve body, the use of the separating limit ring can reduce the volume of the strip valve core, thereby saving materials and reducing production costs; at the same time, due to the provision of the separating limit ring, friction between the side of the strip valve core and the inner wall of the vertical valve body is avoided, thereby reducing wear, extending its service life, and reducing repair and maintenance costs.

[0021] Furthermore, any communication channel is provided with a corresponding pair of water inlets and water outlets on the vertical valve body, and the communication channel matches the corresponding water inlets and water outlets one by one.

[0022] In this technical solution, when the valve is closed, the entrance of the connecting channel cuts off the water flow, and the water inlet and outlet correspond to the connecting channel one by one, and the water flow is diverted on the vertical valve body, reducing the resistance of the strip valve core to cut off the water flow, making it easier to close the valve body; similarly, it can also facilitate the opening of the valve and reduce the difficulty of opening.

[0023] Furthermore, the blocking side of the vertical valve body is provided with an extension edge, and the extension edge is symmetrically arranged on both sides of the vertical valve body and extends to the bottom of the vertical valve body.

[0024] In the present technical solution, the arrangement of the outer extension edge and its extended arrangement facilitate the fixing of the strip valve core on the dam body, thereby improving its stability and avoiding loosening under long-term water flow impact, thereby improving its reliability.

[0025] Furthermore, the bottom of the vertical valve body is closed and the top is provided with an opening, and a detachable rotating handle is provided outside the vertical valve body, and the rotating handle is connected to the strip valve core.

[0026] In the technical solution, the strip valve core is rotated by rotating the handle, which is easy to operate; the bottom seal also facilitates the strip valve core to be limited on the valve body.

[0027] Another object of the utility model is to provide an assembled dam, comprising a dam body and the above-mentioned valve for water level control; the dam body is provided with an installation position penetrating through both sides of the dam body, and the valve is arranged on the installation position.

[0028] In the present technical solution, the prefabricated dam is a reinforced concrete gravity dam, and valve fixing connectors can be pre-embedded at the installation position. Through the setting of valves, selective connection or isolation of different heights of the pools on both sides of the dam body can be achieved, which can adapt to various situations in actual work and meet different needs.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] (1) Through the arrangement of multiple communication groups and communication channels with different orientations, the valve of the present utility model can be selectively conducted or blocked at different heights, with strong adaptability and simple operation. In an artificial wetland, separate conduction between different subsurface flow layers can be achieved to meet different requirements.

[0031] (2) When releasing water flow, the water flow to be released can be selected at the corresponding height according to the requirements of the wetland type to adjust the water level, thereby realizing the conversion of different types of wetlands. Moreover, since the water level is adjusted in this solution without permeating from the bottom, but the water flow is released from the corresponding height, the water level can be adjusted quickly in this way, improving the efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] The drawings of the present utility model are only for illustrative purposes and should not be construed as a limitation to the present utility model. For better illustration of the following embodiments, some components in the drawings will be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0042] Example 1

[0043] Reference Figures 1 to 4 , this embodiment provides a valve 500 for water level control 400, a hollow vertical valve body 100; a strip-shaped valve core 200 rotatably arranged in the vertical valve body 100; at least two communication groups 210 vertically distributed on the strip-shaped valve core 200, each communication group 210 includes a number of communication channels 220; the communication groups 210 face in different directions; an inlet 111 and an outlet 121 corresponding to the communication channels 220 are respectively arranged on the blocking side 110 and the conducting side 120 of the vertical valve body 100.

[0044] The vertical valve body 100 is a structure installed on the dam body 400. The communication channels 220 allow water to flow through. Water enters the communication channels 220 from the inlet 111 on the blocking side 110 of the vertical valve body 100 and then flows out from the outlet 121 on the conducting side 120. Different communication groups 210 correspond to different underflow layers, and the communication groups 210 face in different directions, that is, different communication channels 220 face different directions, so that different communication groups 210 are not simultaneously conducted, realizing the selective on-off control of different underflow layers, meeting different requirements in the actual operation of artificial wetlands, and adapting to more different situations.

[0045] Each communication group 210 includes at least two communication channels 220. For example, the number of communication channels 220 in each communication group 210 can be two, three, four, etc. The communication channels 220 are horizontally arranged, and the distances between adjacent two communication channels 220 in the same communication group 210 are equal. The heights of the communication channels 220 on the strip-shaped valve core 200 are different, and the communication channels 220 in the same communication group 210 face the same direction. A separation limiting ring is arranged between any two communication groups 210. The separation limiting ring is used to limit the strip-shaped valve core 200 in the vertical valve body 100 and separate different communication groups 210; compared with the strip-shaped valve core 200 being limited in the vertical valve body 100 by itself, using the separation limiting ring can reduce the volume of the strip-shaped valve core 200, thereby saving materials and reducing production costs; at the same time, due to the setting of the separation limiting ring, the friction between the side surface of the strip-shaped valve core 200 and the inner wall of the vertical valve body 100 is avoided, reducing wear, extending its service life, and reducing the maintenance cost.

[0046] In this embodiment, the strip-shaped valve core 200 is a cylinder. Three communication groups 210 are arranged on the strip-shaped valve core 200, each communication group 210 includes three communication channels 220, and the outlets of the communication channels 220 are arranged on the cylindrical wall of the strip-shaped valve core 200, and its shape includes but is not limited to being circular. The outer wall of the vertical valve body 100 is square.

[0047] The setting of multiple connecting channels 220 can improve the water flow efficiency and prevent blockage; at the same time, compared with the setting of a single connecting channel 220, multiple connecting channels 220 can divert the water flow, reduce the impact of the water flow on the valve body, and facilitate the maintenance of the valve body. The horizontal setting of the connecting channel 220 facilitates the control of its height and improves the accuracy of height control; the distance between two adjacent connecting copper strips is equal, so that the flow distribution of water is uniform when it flows through the connecting group 210, further reducing the impact of the water on the valve body, especially when the valve body is opened. Different connecting channels 220 are distributed in the vertical direction, so that different heights of the subsurface flow layer can be connected, so that the water body is evenly distributed in the subsurface flow layer; the connecting channels 220 in the same connecting group 210 have the same direction, so that the connecting channels 220 in the same connecting group 210 can be opened synchronously, increasing the connection speed.

[0048] Any communication channel 220 is provided with a corresponding pair of water inlets 111 and water outlets 121 on the vertical valve body 100, and the communication channel 220 matches the corresponding water inlets 111 and water outlets 121 one by one. The positions and shapes of the water inlets 111 and water outlets 121 match the communication channel 220 one by one.

[0049] The blocking side 110 of the vertical valve body 100 is provided with an extension edge 112, and the extension edge 112 is symmetrically arranged on both sides of the vertical valve body 100 and extends to the bottom of the strip core body. The provision of the extension edge 112 and its extension facilitate the fixing of the strip valve core 200 on the dam body 400, improve its stability, and avoid loosening under long-term water flow impact, thereby improving its reliability. Furthermore, the extension edge 112 is also provided with a mounting hole, and the dam body 400 is also provided with a circular hole corresponding to the mounting hole. The fastener passes through the mounting hole and the corresponding circular hole to fix the vertical valve body 100 on the dam body 400.

[0050] The bottom of the vertical valve body 100 is closed and the top is provided with an opening. The vertical valve body 100 is provided with a detachable rotating handle 300, and the rotating handle 300 is connected to the strip valve core 200. The strip valve core 200 is rotated by the handle, and when the communication channel 220 on the valve core corresponds to the water inlet 111 and the water outlet 121 of the vertical valve body 100, the corresponding communication group 210 is connected, and when the communication channel 220 is completely staggered with the water inlet 111 and the water outlet 121 of the vertical valve body 100, the corresponding communication group 210 is closed.

[0051] The valve of this embodiment adopts the form of one valve with multiple outlets at different heights, which automatically realizes the stability of multi-water level control and is easy to operate, thereby realizing the mutual conversion of different artificial wetland types, and can further play the extended functions of artificial wetlands such as sewage treatment, flood storage, water storage, and landscaping.
