Description

River barrage monomer and river barrage

Technical Field

The utility model relates to the technical field of dams, in particular to a river barrage formed by a single barrage and a combination thereof.

Background

The water storage of the river can not only build a beautiful landscape, but also have the effect of water and soil conservation. Along with the enhancement of environmental awareness and the improvement of life quality, people pay more attention to the protection of ecological environment and life quality. Whereas the aqueous environment is the most important part of the ecological environment. Because the precipitation amount can be greatly changed throughout the year, the water flow of the river channel can be obviously divided into a dead water period and a rich water period. Ideally, there is no obstruction in the river course in the period of high water with abundant rainfall, and can discharge flood rapidly, and in the period of low water, because the river course water level is very low, many places lack water seriously, at this moment, the water storage can be carried out through the barrage to solve the problem of lack water. Therefore, construction of a water conservancy junction is very important, and a scheme of constructing a fixed type barrage in a river course may cause blockage of the river course. And the elevation of the river bed, the foundation is eliminated in the medium and small river management system. The scheme of replacing the hydraulic lifting dam mainly comprises a hydraulic lifting dam, a mechanical rotary base rotary dam, a steel structure lifting gate, a pneumatic shield-shaped gate, a pneumatic floating body dam and the like, and the application of the dams achieves good effects.

However, there are also serious problems in the application of these dams. The hydraulic dam has the obvious defect that once a hydraulic system fails, hydraulic oil can leak, so that river pollution is caused. And cannot be used in many scenarios. The mechanical rotating base rotary steel structure dam is extremely difficult to maintain and has high manufacturing cost. And meanwhile, the service life is limited, and the underwater mechanical system has a very unstable factor. The steel structure lifting gate has a plurality of defects, the pneumatic shield ZHA gate and the pneumatic floating body dam are the most advantageous two dam types, and the pneumatic shield ZHA gate and the pneumatic floating body dam have the common characteristics of simple structure, convenient installation, rapid operation, low use cost and high safety.

Currently existing pneumatic shield dams also find several problems in use. One is that the dam cuts off the river channel during the river blocking work, which can cause the water environment aquatic organisms to be unable to migrate and influence ecology. The other is that in urban environment, the dam crest overflows and falls down directly, the fall is large, and large noise is generated, so that rest of surrounding residents can be influenced at night. This problem has become a hot spot for contradiction in many places, and many places have caused complaints of residents because of the problem, influence rest, and the problem of noise disturbing the residents is required to be solved by taking measures. The existing pneumatic shield dam mainly comprises three structures, namely a front water blocking gate shield plate, a high-strength air bag and a water blocking shield plate limit belt. In the work of the device, the air bag is inflated through the air compressor, the size of the air bag is increased, and the shield plate is jacked up to carry out water blocking. When the air bag is deflated, the air bag volume is reduced, and the shield falls down, so that the falling of the pneumatic shield dam is realized. However, since the existing pneumatic shield dam is not provided with a guide plate for guiding water flow, the river is blocked when the dam works, and huge water flow falling noise can be generated when the ecological channel of aquatic organisms is blocked. Based on the applicant, a shield dam with a deflector is provided, for example, in patent CN115419025a filed by the applicant, which is added with a deflector to guide water flow through the dam top, so that the generation of drop noise of the water flow is inhibited, and meanwhile, the lifting height of the deflector can be controlled to facilitate the migration process of the migration organisms. However, in practical application, the applicant finds that sediment is easily accumulated on the baffle, which makes it difficult for the air bag to drive the baffle and the baffle to lift.

Detailed Description

In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.

Referring to fig. 1 to 4, a single body of a barrage includes a baffle 2, a baffle 3, a sliding structure and a driving structure; one end of the water baffle 2 is hinged to the river bottom 1; the guide plate 3 comprises a first plate body 31 and a second plate body 32, one end of the first plate body 31 is hinged with the other end of the water baffle 2, the other end of the first plate body 31 is lapped on the surface of one end of the second plate body 32 through the sliding structure, the other end of the second plate body 32 is hinged with the river bottom 1, and the other end of the first plate body 31 slides towards the hinged end of the second plate body 32 and the river bottom 1 on the surface of the second plate body 32 in the process from a working state to a lodging state of the river dam monomer; the driving structure is arranged between the water baffle 2 and/or the guide plate 3 and the river bottom 1, and is used for controlling the included angles between the water baffle 2 and the guide plate 3 and the river bottom 1.

The barrage is installed in a river channel, and the river bottom 1 is the basis for installing the barrage monomers. Because one end of the water baffle 2 is hinged with one end of the guide plate 3, the other end of the water baffle is hinged with the river bottom 1, and the other end of the guide plate 3 is hinged with the river bottom 1, the whole river dam is in a triangular shape when the water baffle 2 and the guide plate 3 are in a lifting state (transition state) to a working state. Wherein, when the installation, the breakwater 2 is installed in rivers upstream one side for stop rivers, and the guide plate 3 is installed in rivers downstream one side, is used for flowing through the rivers guide flow down on breakwater 2 top, consequently the setting of this guide plate 3 can effectively avoid the rivers directly to fall to the produced noise of river bottom 1 surface from the top of breakwater 2 directly. Of course, since the elevation height of the deflector 3 is adjustable, the included angle β formed between the deflector 3 and the river bottom 1 can be adjusted to adapt to the migration process of the migration organisms, that is, the angle most suitable for most migration organisms to migrate (that is, the included angle β) is preset according to the characteristics of the migration organisms in the river channel, so as to ensure ecological balance in the river channel.

It should be noted that, in this context, the working state does not refer to only the maximum height at which the barrage monomer can rise, but also includes the optimal working height (below the maximum height) controlled according to actual needs. The lodging state refers to a state when the single body of the barrage is reduced to the lowest position. The lifting state or the transition state refers to a continuous state from a working state to a lodging state or from the lodging state to any moment in the working state of the barrage monomer.

In this context, the articulation may take any of the existing articulation means that achieve the desired effect, such as by means of a pin connection.

In this embodiment, the first plate 31 partially overlaps the surface of the second plate 32, and the two plates are connected by a sliding structure and maintain the connection tightness therebetween, so as to avoid an undesired water leakage phenomenon during the relative sliding of the two plates. Preferably, the sliding structure includes, but is not limited to, a bearing roller and a corresponding sliding rail. Desirably, the sliding structure allows the portion of the first plate 31 to slide freely on the surface of the second plate 32 while the junction therebetween ensures a certain waterproof sealing property. That is, in this embodiment, the entire baffle 3 is telescopic, so that the entire volume and installation width of the barrage in the laid state can be effectively reduced. The sliding process of the first plate body 31 on the surface of the second plate body 32 is not only the whole expansion process of the guide plate 3, but also the cleaning process of the first plate body 31 on the sediment on the surface of the second plate body 32. Referring specifically to fig. 1 to 3, since the sliding structure is disposed at the end of the first plate 31, when the two slide relatively, the end of the first plate 31 may directly contact with the surface of the second plate 32, or a small gap exists between the end of the first plate 31 and the surface of the second plate 32, so that the sediment and the larger sand on the surface of the second plate 32 may be pushed by the end of the first plate 31, so as to clean the surface of the second plate 32. Preferably, the first plate 31 completely covers the second plate 32 when the barrage is in a lodged state.

In one embodiment, the driving structure comprises an air bag 5 connected with an air compressor, wherein the air bag 5 is arranged at an included angle between the water baffle 2 and/or the guide plate 3 and the river bottom 1, namely, the air compressor controls the expansion and contraction of the air bag 5 so as to control the lifting height of the water baffle 2 and/or the guide plate 3. In an alternative embodiment, the air bags 5 are arranged at the included angles between the water baffle 2 and the river bottom 1 and between the guide plate 3 and the river bottom. In this embodiment, due to the arrangement of the guide plate 3, sediment and the like can be effectively prevented from entering the interior of the dam monomer, so that the situation that the air bag 5 is damaged due to the fact that hard sundries such as sediment enter the air bag 5 is avoided, namely, the air bag 5 is effectively protected. However, it is difficult for the air bag 5 to precisely control the elevation height of the water deflector 2 and the deflector 3. Therefore, it is preferable to provide the baffle 3 and the water baffle 2 with the limiting belts 4, for example, the limiting belts 4 limit the included angle β formed between the baffle 3 and the river bottom 1 to be less than or equal to 41 °, so as to avoid difficult migration of the migratory animal due to the overlarge included angle β.

In a preferred embodiment, the working angle of the water deflector 2 in the barrage (the angle formed between the water deflector 2 and the river bottom 1) is 55 °, the angle of the water deflector 3 (the aforementioned angle β) is 41 °, and the angle α formed between the water deflector 2 and the first plate 31 is 84 °. Wherein, the included angle α determines the rotation angle of the baffle 3, when the baffle 3 rotates to a smaller angle, because it is a double-layer lap joint structure, the double-layer lap joint structure is easy to be jammed in the falling process of the barrage monomer, that is, the situation that the barrage monomer is jammed by rotating inwards to dead angle occurs, so in order to ensure that the barrage monomer can fall completely, the angle of the included angle α is preferably limited by a limiting piece, and is preferably 84 ° less than or equal to α < 180 °. In an alternative embodiment, as shown in fig. 4, the limiting member is a working surface 311 formed at one end of the first plate 31, and when the deflector 3 rotates to a desired working angle (e.g., 84 °), the working surface 311 abuts against the back surface of the deflector 2, that is, prevents further lifting of the deflector 2 by the abutting process, and limits further rotation of the first plate 31. The working surface 311 is prefabricated according to a desired design angle when being arranged, so that the working surface can be designed according to actual needs.

In order to realize unpowered dam reduction, so as to meet the requirements of special situations, a manual valve is preferably arranged on a deflation pipeline connected with the air bag 5, namely after the manual valve is opened, the air in the air bag 5 is extruded by using the pressure of the water passing on the water baffle 2 and the water baffle 3, and no power equipment is needed in the process, so that no dam reduction obstruction exists in the special situations.

A kind of barrage is obtained by at least two aforesaid barrage monomer of linear arrangement are spliced, namely in this embodiment, can choose the suitable barrage monomer quantity to install according to the concrete width of river course. In the period of high water yield, the same control on river water flow can be realized by adopting the single river blocking dam with uniform height, and the influence on the migration process of migration organisms caused by the height of the single river blocking dam is not required to be considered due to the abundant water quantity. However, in the dry period, that is, in the low-level operation of the water retaining section (on one side of the water retaining plate 2), it is difficult to form a flowing layer with a certain thickness on the top of the water retaining plate 2 for the migration of the migration organisms to move freely, so that it is preferable to splice at least two types of river blocking dam monomers with different working heights, that is, at least one of the river blocking dam monomers has a working height lower than that of at least one adjacent river blocking dam monomer, preferably the working height of the low-level river blocking dam monomer is lower than that of the high-level river blocking dam monomer by 0.3m, that is, in this way, a low-level migration concentration area can be formed in the river channel, so that the migration organisms can move freely across the river blocking dam in the dry period, that is, the living habits of the migration organisms are not destroyed or changed. In order to further increase the thickness of the water flow at the bottom of the low-level barrage, the included angle beta in the low-level barrage is preferably limited to be less than 30 degrees.
