Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction, in particular to a channel drainage interception device. Background Art

[0002] The construction of water conservancy projects is used to control water flow, prevent flood disasters, and regulate and distribute water to meet the people's needs for water resources for life and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, channels, etc. to achieve their goals.

[0003] In the current water conservancy construction channels on the market, linear and flocculent materials are entangled into balls during actual application. When blockage occurs, they are mostly entangled inside the pump body and are difficult to remove. The existing drainage interception device is not convenient for interception and regulation, which greatly affects the water interception effect of the water conservancy construction channel, causing some water to continue to be discharged, affecting construction.

[0004] In order to solve the above problems, the utility model patent with publication number CN217267573U discloses a channel drainage intercepting device for water conservancy construction, which is provided with a stable base at the bottom of the intercepting vertical cylinder, and two column round rods are fixedly installed on the top of the stable base, so that the connecting support is movably sleeved, and a sleeve rotating cylinder is fixedly installed on the top of the stable base, so that the adjusting screw can be rotatably sleeved, and a threaded cylinder is fixed at the bottom of the connecting support through a fixed sleeve, so that the top end of the adjusting screw is threadedly sleeved with the threaded cylinder, so that the support height of the intercepting vertical cylinder can be quickly and conveniently adjusted, so that the intercepting vertical cylinder is suitable for connecting drainage pipes of different heights.

[0005] When the above-mentioned channel drainage interception device for water conservancy construction is actually used, different weather changes require adjustment of the water flow size in the channel.

The annular groove provides a space for the fan-shaped regulating plate 9, and the guide groove 10 ensures that the moving direction of the fan-shaped regulating plate 9 is linear. The water in the channel 1 flows from one side to the other side after passing through the first shell 2. By moving the fan-shaped regulating plate 9, the gap between adjacent fan-shaped regulating plates 9 can be accurately controlled, thereby achieving the purpose of regulating the size of the water flow.

[0033] refer to Figure 3 The drainage interception device of channel 1 includes a filter screen 11, which is installed in the channel 1. The water flow in the channel flows through the filter screen 11 and flows to the water flow regulating component, which can effectively intercept impurities and solid particles in the channel 1, so as to keep the channel 1 unobstructed.

[0034] like Figure 1 and Figure 6As shown, the drainage intercepting device of the channel 1 also includes a support frame 12 installed on both sides of the channel 1, and a second driving part and a scraper 19 are arranged on the support frame 12. The second driving part includes a second shell 13 fixed on the support frame 12, and a mounting bracket 14, a motor 15, a rotating bracket 17, a rotating shaft 16 and a connecting rod 18 are arranged on the second shell 13. A notch 20 is opened on the bottom surface of the second shell 13; the mounting bracket 14 and the motor 15 are fixed in the second shell 13, the rotating bracket 17 is fixed to the rotating shaft 16, and the rotating bracket 17 is rotatably connected to the mounting bracket 14 through the rotating shaft 16, one end of the rotating shaft 16 is connected to the motor 15, the upper end of the connecting rod 18 passes through the notch 20 and is fixed to the rotating bracket 17, and the lower end is fixed to the scraper 19.

The swing of the rotating frame drives the scraper 19 to swing back and forth through the connecting rod 18. The scraper 19 scrapes impurities on the inner wall of the scraping channel 1 to keep the inside of the channel 1 clean and prevent blockage and siltation inside the channel 1.

[0035] The working principle of the device in this embodiment is as follows:

[0036] When the water flow needs to be adjusted, the rotating rod 3 is first rotated, and the rotating rod 3 drives the gear 4 to rotate, thereby driving the toothed disc 5 to rotate, and the rotation of the toothed disc 5 drives the multiple curved slide grooves 6 to push the fixed rod 7 to move, and the movement of the multiple fixed rods 7 drives the sliding plate 8 to slide inside the guide groove 10, thereby driving the gaps between the multiple fan-shaped adjustment plates 9, so as to achieve the purpose of controlling the size of the water flow;

[0037] The filter 11 can filter impurities and solid particles in the water flow, thereby preventing the channel 1 from being blocked or damaged and keeping the channel 1 unobstructed. When impurities are accumulated in front of the filter 11, the motor 15 is started, and the scraper 19 is driven by the motor 15 to scrape the inner wall of the channel 1, so that the impurities accumulated inside the channel 1 can be cleaned to both sides of the outside of the channel 1, so as to keep the inside of the channel 1 clean. When swinging, the notch 20 can guide the connecting rod to prevent it from shaking, and on the other hand, it can also limit the maximum swing amplitude of the scraper 19.
