Problems solved by technology

[0002] The gates for water conservancy projects are movable structures used to open and close water outlets such as river channels and reservoirs. In most cases, the gates are in a closed state. Under the impact of upstream water flow, a large amount of floating matter and aquatic plants will accumulate in front of the gates. If the gate is opened directly when the gate needs to be opened, it is easy to make the accumulated sundries enter the downstream river, thus causing cross-infection of pollutants in each river. Therefore, it is necessary to improve the structure of the gate so that it can not only protect the river water The control of the flow can also reduce the situation that the debris in the upstream of the river enters the downstream to pollute the water quality

Embodiment 1

[0031] Such as Figure 1-Figure 7 Shown, a kind of river channel gate with filtering interception function, comprises dam abutment 10, support 20, opening and closing degree adjustable gate mechanism 30 and filter screen 40, on dam abutment 10 straddles support 20, and support 20 and dam abutment 10 Adjustable opening and closing degree gate mechanism 30 is arranged between, and the side of opening and closing degree adjustable gate mechanism 30 is provided with filter screen 40, and filter screen 40 is used for intercepting the sundry in the river channel, can intercept the floating in the river channel by filter screen 40 Matter and aquatic plants and other sundries can reduce their influence on the gate, while the opening and closing degree adjustable gate mechanism 30 can change the opening and closing degree of the gate according to needs, so as to control the water flow in the river channel;

[0032] The opening and closing adjustable gate mechanism 30 is set to include ...

Embodiment 2

[0042] Such as Figure 1-Figure 7 As shown, the difference from Embodiment 1 is that, further, a debris scraping mechanism 50 is set on the dam platform 10, and the debris scraping mechanism 50 is set to include a motor 2 501, a lead screw 502, a feed rod 503, a lead screw The auxiliary 504 and the scraper 505, the second motor 501 are fixed on the dam platform 10, and the output end of the motor shaft of the second motor 501 is connected to one end of the lead screw 502, and the lead screw 502 and the light rod 503 are all erected on the dam platform through the support base 10, and the lead screw 502 and the light rod 503 are fitted with a lead screw pair 504, the lead screw pair 504 is connected to the upper end of the scraper 505, and the lead screw pair 504 can move linearly along the lead screw 502 to drive the scraper 505 scrapes off the sundries on the filter screen 40, and the scraper 505 fits with the outer wall of the filter screen 40, and drives the leading screw 5...

Embodiment 3

[0045] Such as Figure 1-Figure 7 As shown, the difference with Embodiment 2 and Embodiment 3 is that, further, a sundry push-out mechanism 60 is arranged outside the filter screen 40, and the sundry push-out mechanism 60 is fixed on the dam platform 10, and the sundry push-out mechanism 60 can It is set to include a horizontal installation groove 601, a motor three 602 and a feeding screw 603. The horizontal installation groove 601 is fixed on the dam platform 10, and a discharge port 604 is provided on the bottom wall of the end of the horizontal installation groove 601. The three motors 602 are arranged on the horizontal In the inner cavity of the beginning end of the installation groove 601, and the output end of the motor shaft of the motor three 602 is connected to the feed screw 603, and the feed screw 603 pushes the sundries to the discharge port 604 to be discharged, and the three motors 602 drive the feed screw 603 to rotate, so as to The sundries such as floating ma...

Abstract

The invention provides a river channel gate with a filtering and intercepting function. The river channel gate with the filtering and intercepting function comprises a dam platform, a support, an adjustable opening degree gate mechanism and a filter net, the support is arranged on the dam platform in a spanning mode, the adjustable opening degree gate mechanism is arranged between the support andthe dam platform, and the filter net is arranged on the side of the adjustable opening degree gate mechanism. The adjustable opening degree gate mechanism is arranged as comprising an installing box body, a first motor, a transmission assembly and a plurality of groups of special-shaped baffles, water through holes are formed in the installing box body, the input end of the transmission assembly is connected to the output end of the first motor, and the transmission assembly controls the occlusion areas of the multi-group special-shaped baffles to the water through holes; and the sum of the areas of the multi-group special-shaped baffle is larger than the areas of the water through holes, and the side walls of the special-shaped baffles are attached to the inner side wall of the installingbox body. The river channel gate with the filtering and intercepting function is adopted, the opening degree of the gate can be controlled to ensure the water flow in a river channel according to thedemand, floating materials, water grasses and other sundries can be intercepted in the river channel, the influence on the gate is reduced, and the intercepted sundries are conveniently sent out fromthe bottom of a river.
