Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and particularly relates to a river channel pollution interception and flood control grid. Background Technique

[0002] In water conservancy projects, a river channel is the route through which river water flows. During the flow of the river water in the river channel, it may carry waterweeds, driftwood or various plastic wastes. Driven by the river water, these pollutants will flow to various parts of the river channel, which will affect the water quality of the river water. In order to control such pollutants, pollution interception grids are usually installed at the water inlet and the water outlet in the river channel. The pollution interception grid is used to intercept various sundries carried by the water flow, so that the sundries are not easily introduced into the water channel, so as to ensure that the sluice, the gate, the water turbine, the pump water turbine, etc. are not damaged, ensure the normal operation of the equipment, and thus play a certain role in flood control for the control of the river water flow.

[0003] A kind of water conservancy river channel pollution interception and flood control grid described in the publication number CN219951859U includes a vertical plate. One end of the vertical plate is fixedly connected with a connecting block, and one end of the connecting block is rotatably connected with a first support rod. The advantages of the utility model are as follows: pulling the vertical plate, the first support rod rotatably connected by the connecting block and the second support rod rotatably connected at one end extend and unfold. The pollution interception net arranged inside the first support rod and the second support rod is stretched by the movement of the vertical plate, and the staff can adjust the pollution interception net according to the width of the river channel, and the practicability is relatively high. When the first support rod and the second support rod are adjusted, the limit slide rod at the bottom of one end of the first support rod will slide in the limit chute opened on the first fixing plate and the second fixing plate to limit the first support rod and the second support rod. The connecting plate fixed at one end of the first fixing plate slides inside one end of the second fixing plate to limit the vertical plate, which relatively improves the stability of the pollution interception and flood control grid.

[0004] The information disclosed in this background technical part is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

[0005] Although the above flood control grid solves certain problems, it still has the following disadvantages:

[0006] (1) The river channel pollution interception and flood control grid is supported by inserting two poles on both sides inside the river channel. The stability of the support is poor. As the amount of garbage accumulated on the flood control grid increases, it is easy to be washed down by the water flow.

[0007] (2) The mesh of the river channel pollution interception and flood control grid is fixed and the size cannot be changed. During the flood season, it is impossible to quickly increase and adjust the flowing water area of the river channel pollution interception and flood control grid.

[0008] (3) After the river channel garbage intercepted by the river channel pollution interception and flood control grid is intercepted, it is relatively troublesome to clean up. Content of the Utility Model

[0042] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1:

[0045] As Figures 1 to 7 shown, this embodiment provides a river channel trash and flood prevention fence, including a base platform 1, a second fence 2, a control mechanism 3, a driving mechanism 4, a limiting mechanism 5, a support platform 6, a first fence 7, a hanging column 8, a fixed anchor 9, and a scraping convex rod 10 fixedly connected to a rotating shaft 302 between the support platforms 6.

[0046] Among them, the support platforms 6 are arranged on both sides of the river channel, and the cross-section of the support platform 6 is an isosceles trapezoid with inclined surfaces at the front and back. A base platform 1 is arranged below the support platform 6. The two support platforms 6 are symmetrically arranged, and the lower ends of the support platforms 6 are respectively fixedly connected to both sides of the upper end of the base platform 1. The base platform 1 is fixed to the bottom of the river channel by a number of evenly distributed fixed anchors 9 at the bottom to increase the stability of the support platform 6 and the base platform 1. A first fence 7 is arranged on the front side between the support platforms 6. The grids inside the first fence 7 are vertical, and the gaps formed between the grids are used for water flow. The dirt and garbage in the river channel are intercepted through the grids. Moreover, the gaps between the grids inside the first fence 7 are communicated with the upper end outside the first fence 7, and there is no obstruction at the upper end of the gaps between the grids inside the first fence 7. The first fence 7 is parallel to the front surface of the support platform 6. The inclined fence can reduce the vertical impact of water flow, reduce wear, and increase durability. In addition, both sides of the front end of the first fence 7 are connected to the support platform 6 by two reinforcing baffles through bolts for reinforcement.

[0047] A second barrier 2 is also provided between the support platforms 6. The second barrier 2 is parallel to the first barrier 7, and the front side of the second barrier 2 is in contact with the rear side of the first barrier 7. The grids inside the second barrier 2 are horizontal. A number of evenly distributed hanging columns 8 are fixedly connected to the front end of each grid. The hanging columns 8 can move upward through the second barrier 2 within the gaps between the grids in the first barrier 7. The hanging columns 8 scrape and lift upward the dirt, garbage, etc. intercepted by the front side of the first barrier 7, facilitating cleaning. At the front position on the side where the support platforms 6 are close to each other, a limiting card slot 502 parallel to the front side of the support platform 6 is opened. Limiting track bars 501 are fixedly connected to both sides of the second barrier 2. The second barrier 2 is clamped by the limiting card slot 502 and the limiting track bars 501, so that the second barrier 2 can only move up and down parallel to the first barrier 7 along the inclined direction inside the limiting card slot 502 to limit the second barrier 2.

[0048] To drive the second barrier 2, a rotating shaft 302 is provided between the support platforms 6. Both ends of the rotating shaft 302 are rotatably connected to the side where the support platforms 6 are close to each other. A number of evenly distributed scraping convex bars 10 are fixedly connected to the surface of the rotating shaft 302 to scrape some flocculent and strip-shaped floating objects floating on the river surface after the second barrier 2 rises, increasing the sewage interception effect on the river channel. Driving gears 303 are rotatably connected to the side where the support platforms 6 are close to each other. A retaining bar 301 is fixedly connected to both ends of the rear side of the second barrier 2. A number of evenly distributed transmission tooth grooves 304 are opened on the rear side of the retaining bar 301. The transmission tooth grooves 304 are engaged with the teeth of the driving gears 303. The rotation of the driving gears 303 drives the retaining bar 301 to move up and down, and the second barrier 2 is driven to move up and down.

[0049] On the front side of the upper end of the support platform 6 on one side, an installation cavity 401 is opened. One end of the rotating shaft 302 extends into the interior of the installation cavity 401. A worm gear 402 is arranged inside the installation cavity 401. The worm gear 402 is fixedly connected to one end of the rotating shaft 302 extending into the interior of the installation cavity 401. It is driven by a worm 403 installed at the rear side inside the installation cavity 401 and meshing with the worm gear 402. By utilizing the characteristic that the worm 403 can drive the worm gear 402 while the worm gear 402 cannot drive the worm 403 in reverse, the worm gear 402 is driven to rotate, and the rotating shaft 302 rotates in a self-locking manner, realizing the self-positioning lifting of the second barrier 2. A servo motor 11 is fixedly connected to the upper end of the support platform 6 where the installation cavity 401 is opened. The output end at the lower end of the servo motor 11 is fixedly connected to the rotating shaft at the upper end of the worm 403. The worm 403 is driven to rotate by the servo motor 11. During normal use, the second barrier 2 is lowered, and the river channel is intercepted by the grid formed by the vertical and horizontal grids between the first barrier 7 and the second barrier 2. When the flood season arrives or the barriers need to be cleaned, by moving the second barrier 2 upward, the hanging column 8 hooks up the intercepted river channel garbage, facilitating cleaning. And during the flood season, due to the upward movement of the second barrier 2, only the grids of the first barrier 7 are used for blocking, the flow area increases, and the interception hole area increases, as Figure 3 shown, increasing the flow of water.

[0050] All the electrical components mentioned in this article are electrically connected to the external main controller and 220V mains electricity. And the main controller can be a conventional known device such as a computer for control. The detailed descriptions of known functions and known components are omitted in the specific implementation manners of the present disclosure. To ensure the compatibility of the device, the operating means adopted are consistent with the parameters of market instruments.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
