DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] A drainage device for water conservancy and hydropower, such as Figures 1 to 4 As shown, it includes a drainage pipe 1 installed on the canal dam, a pumping and filtering mechanism 2 is arranged at the top of the drainage pipe 1, and a convenient drainage mechanism 3 is arranged inside the drainage pipe 1.

[0023] The water pumping and filtering mechanism 2 includes an outer sleeve 201, a rotating drum 202, a water wheel 203, and an inner sleeve 205. The outer sleeve 201 is clamped on the water inlet end of the drainage pipe 1, the rotating drum 202 is sleeved on the inner wall of the outer sleeve 201, and a water wheel 203 is installed on the inner wall of the rotating drum 202. A plurality of fixing plates 204 are arranged on the inner wall of the outer sleeve 201 corresponding to the upper part of the water wheel 203, and the other end of the fixing plate 204 is connected to the bottom bolt of the inner sleeve 205.

[0024] When water flows in from the top of the inner sleeve 205 or the gap between the inner sleeve and the outer sleeve, the water will impact the water wheel and make it rotate during the downward movement. During the rotation of the water wheel, eddy suction is generated, which can speed up the efficiency of pumping water.

[0025] A number of guide plates 206 are evenly distributed between the inner sleeve 205 and the outer sleeve 201. The guide plates 206 can be snapped in or fixedly connected between the inner sleeve 205 and the outer sleeve 201 to play a guiding role. The cooperation between the guide plates 206 and the water wheel 203 can increase the rotation speed of the water wheel, thereby facilitating rapid water pumping.

[0026] A filter is installed between the top of the inner sleeve 205 and the top of the outer sleeve 201 to prevent impurities in the water from being discharged into the drainage pipe along with the water flow, causing the drainage pipe to be blocked and affecting drainage.

[0027] The filter includes a first filter screen 207 installed on the top of the inner sleeve 205 and a second filter screen 208 installed on the outer side wall of the inner sleeve 205 and the top of the outer sleeve 201 .

[0028] A plurality of scrapers 6 are installed on the inner wall of the inner sleeve 205 located above the first filter screen 207. The centripetal ends of the scrapers 6 are respectively connected to the mounting blocks 5 arranged in the center. The mounting blocks 5 are threadedly connected to the top ends of the vertical rods 4. The bottom ends of the vertical rods 4 are installed in the center of the water wheel 203. The impurities on the first filter screen 207 can be cleaned to prevent the impurities in the water from being stuck in the gaps of the filter screen and affecting drainage.

[0029] A grille sleeve 7 is also installed on the top of the inner sleeve 205 to protect the scraper 6, so as to prevent fish in the water from contacting the scraper during the rotation of the scraper.

[0030] The outer sleeve 201 includes a vertical portion and an expansion portion. The rotating drum 202 is sleeved on the vertical portion of the outer sleeve. The inner sleeve 205 expands upward in a trumpet shape to expand the drainage area.

[0031] The height of the inner sleeve 205 can be set to be higher than the height of the outer sleeve 201 to facilitate better drainage.

[0032] The convenient drainage mechanism 3 includes a blocking plate 306, a retaining ring 308, and a cross connecting plate 304 installed inside the drainage pipe 1. The cross connecting plate 304 is installed inside the drainage pipe 1. A sliding rod 305 is slidingly arranged at the center of the cross connecting plate 304. The blocking plate 306 is installed at one end of the sliding rod 305 close to the water inlet end. A spring 307 is installed between the blocking plate 306 and the cross connecting plate 304.

[0033] The retaining ring 308 is installed on the inner wall of the drainage tube 201 located in front of the sealing plate 306, and a groove for assembling with the sealing plate 306 is opened at one end of the retaining ring 308 close to the sealing plate 306, wherein the inner diameter of the retaining ring 308 is smaller than the outer diameter of the plug plate 306.

[0034] To ensure the drainage effect, a notch is opened on the outer wall of the drainage pipe 201 corresponding to the cross connecting plate 304, and a fixed frame 301 is arranged around the notch. A slider 303 connected to the end of the cross connecting plate 304 is slidably arranged inside the notch. The slider 303 is threadedly connected to the adjusting rod 302 installed on the fixed frame 301, and can adjust the distance between the cross connecting plate 304 and the sealing plate 306, thereby adjusting the adjustment range of the spring.

[0035] During the drainage process, water flows into the outer sleeve 201 through the inner sleeve 205, flushes the water wheel 203, and causes the water wheel 203 and the rotating drum 202 to rotate inside the outer sleeve 201, forming a vortex to generate suction, thereby improving the pumping effect and facilitating and quickly pumping water from the canal.

[0036] When a part of the water flows through the outer sleeve 201 and the inner sleeve 205, the water flow is deflected by the guide plate 206, and then cooperates with the water wheel 203 to improve the rotation efficiency of the water flow inside the outer sleeve 201, further enhancing the water pumping effect.

[0037] During the pumping process, the first filter screen 207 and the second filter screen 208 cooperate to prevent aquatic plants and impurities from entering the drainage pipe 1 and prevent blockage. At the same time, during the rotation of the water wheel 203, the vertical rod 4 drives the mounting block 5 and the scraper 6 to rotate, so that the scraper 6 cleans the top of the first filter screen 207 to prevent aquatic plants and impurities from getting stuck on the filter screen 207, thereby ensuring the drainage filtration effect.

[0038] When the water inside the rainwater canal increases, the water level rises and the water pressure increases. When the water pressure is greater than the elastic force of the spring 307, the blocking plate 306 will be pushed, so that the blocking plate 306 and the slide rod 305 slide along the inner wall of the cross connecting plate 304. At the same time, the blocking plate is separated from the retaining ring 308, and the seal on the drainage pipe 1 is released, which facilitates the timely discharge of the flow inside the canal, prevents the water level from continuing to increase, and breaks the dam on the canal, thereby increasing safety.

[0039] The position of the cross connecting plate 304 can also be pre-adjusted according to the data of the water level change inside the canal, and the adjusting rod 302 can be rotated so that the adjusting rod 302 can slide on the inner wall of the fixed frame 301 with the cross connecting plate 304 through the slider 303, thereby changing the distance between the cross connecting plate 304 and the retaining ring 308, thereby adjusting the adjustment range of the spring.

[0040] The present invention provides a drainage device for water conservancy and hydropower. Rapid drainage and water discharge are achieved by arranging a pumping and filtering mechanism and a convenient drainage mechanism. No human intervention is required during the drainage process, and the drainage effect is good. During the pumping process, the power of the water flow drives the water wheel to rotate and generates turbine suction, which speeds up the pumping speed and improves the pumping efficiency. Automatic drainage and water drainage are achieved by opening the drainage port through the impact of the water flow on a sealing plate. The accumulated water in the canal can be quickly discharged without human operation.
