Description

Technical Field

[0001] The invention relates to a surface water intake device which automatically rises and falls with the water level and belongs to the technical field of water supply of hydraulic engineering. Background Art

[0002] The conventional practice for setting up the existing water intake (water inlet) is to design a bottom hole, which can also be used for emptying, sand flushing, water supply and irrigation. However, due to the stratification of reservoir water temperature, the low-temperature water discharged is not conducive to the growth of crops, resulting in reduced agricultural production and affecting the production and life of farmers in the irrigation area.

[0003] With the advancement of technology, fixed water intake or stacked beam gate devices are commonly used to achieve stratified water intake. Stacked beam gates use multiple individual gate plates, which are placed horizontally in the gate slots one by one to form a flat water retaining structure. The stacked beam gate has a simple structure, light weight, small lifting force, and is easy to carry. However, since the water stop between the gate plates relies on their own weight to achieve the sealing effect, the integrity of the water retaining structure is poor, the sealing is poor due to the water level, the leakage is large, the management and control devices are complex, the operation is cumbersome, and the leakage is serious during daily operation, resulting in a large waste of water resources. The water intake cannot automatically change with the rise and fall of the water level, and automatic control cannot be achieved.

[0004] In the prior art, a Chinese patent with publication number CN106703121A discloses a reservoir stratified water intake method and structure, which can be applied to stratified water intake of reservoirs, but it mainly uses a water intake tower to take water in stratified form, and the water intake is relatively fixed, and the water intake cannot be automatically operated with the water level. The water intake pipeline of the present application uses an adjustable rubber inflatable cylinder, a concrete counterweight and other telescopic sliding devices to realize the automatic operation of the water intake (water inlet) with the water level. The water intake is always kept at a fixed position under the water surface, ensuring the downstream irrigation water. Water temperature requirements; for example, a Chinese patent with publication number CN206607655U discloses a stratified water intake suitable for the Dashaoluo Reservoir. This patent can also be applied to stratified water intake of the reservoir, but the stratified water intake is achieved by stacked beam doors, which is cumbersome to operate and complex to manage. The sealing between the stacked beam doors is poor and there are leakages. The water intake pipeline of the present application uses telescopic sliding devices such as adjustable rubber inflatable cylinders and concrete counterweights to achieve automatic operation of the water inlet as the water level changes. The water inlet is always kept at a fixed position below the water surface to ensure the water temperature requirements for downstream irrigation water. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a surface water intake device that automatically rises and falls with the water level. The surface water intake device that automatically rises and falls with the water level keeps the water inlet constant at a certain position below the surface water, takes high-temperature surface water, ensures that the downstream water temperature meets the temperature requirements of downstream agricultural production, avoids the impact of low-temperature water discharge on downstream agricultural production, and avoids agricultural production reduction.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0022] like Figures 1 to 3 As shown, a surface water intake device that automatically rises and falls with the water level includes a water intake pipe 10 and a concrete fixed pile 1 vertically arranged on one side of the water intake pipe 10; the water intake pipe 10 is divided into an upper half and a lower half, and the upper half of the water intake pipe 10 is slidably connected to the lower half of the water intake pipe 10 through a sealing ring 7; the lower half of the water intake pipe 10 is connected to the concrete fixed pile 1 through a plurality of second nuts 8, and the upper half of the water intake pipe 10 is slidably connected to the concrete fixed pile 1 through an adjustable rubber inflatable cylinder 3 and a concrete counterweight block 6, and a pressure sensor is provided on the adjustable rubber inflatable cylinder 3.

[0023] Preferably, the water level will rise and fall over time during the operation of the reservoir. According to the buoyancy adjustment control cabinet 18, the dynamic balance parameters of the buoyancy of the adjustable rubber inflatable cylinder 3 and the concrete counterweight 6 are automatically achieved, so that the adjustable rubber inflatable cylinder 3 moves up and down with the rise and fall of the water level, thereby achieving the dynamic balance of the adjustable rubber inflatable cylinder 3 and the concrete counterweight 6.

[0024] The sealing ring 7 is made of rubber.

[0025] The concrete fixed pile 1 is provided with a movable guide rail 4, and the adjustable rubber inflatable cylinder 3 and the concrete counterweight block 6 are slidably connected to the concrete fixed pile 1 through the movable guide rail 4, so that the adjustable rubber inflatable cylinder 3 and the concrete counterweight block 6 can move up and down on the concrete fixed pile 1, and also play the purpose of relatively fixing the adjustable rubber inflatable cylinder 3 and the concrete counterweight block 6, avoiding the impact of water flow on the upper water intake pipe 10.

[0026] The adjustable rubber inflator 3 is provided with a slag barrier 12 to prevent slag or other debris from accumulating and to prevent slag from entering the water intake pipe 10 .

[0027] The water outlet 9 of the water intake pipe 10 penetrates through the dam and is exposed outside.

[0028] A filter screen 13 is provided in the water inlet 2 of the water intake pipe 10 to prevent scum or other debris from clogging the water intake pipe 10 and to retain the scum or other debris outside the water inlet 2 .

[0029] The adjustable rubber inflator 3 is connected to the water intake pipe 10 via a connector 11 (conventional connector).

[0030] The concrete counterweight block 6 is connected to the water intake pipe 10 via a first nut 5 .

[0031] The adjustable rubber inflator 3 is provided with a pressure relief valve 14 and an inflation hole. The inflation hole is connected to a fan 16 via an inflation tube 15 . The pressure sensor is connected to a buoyancy adjustment control cabinet 18 via a parameter acquisition cable 17 .

[0032] Furthermore, the upper half of the water intake pipe 10 can achieve dynamic balance through the adjustable rubber inflator 3 and the concrete counterweight 6, so that the upper pipe can automatically rise and fall with the water level rise, and the water inlet 2 always remains at a certain position below the normal water storage level (using concrete fixed piles 1 and movable guide rails 4 to achieve up and down sliding of the water inlet 2), which can ensure that the water in the water intake pipe 10 is always surface high-temperature water.

[0033] Furthermore, the adjustable rubber inflatable cylinder 3 and the concrete counterweight block 6 move up and down along the movable guide rail 4, which can avoid displacement and left-right swinging due to the impact of water flow.

[0034] Preferably, in order to ensure the normal operation of the water inlet, the scum or other debris around the adjustable rubber inflator 3 and the slag fence 12 must be cleaned regularly to ensure that the water area near the water inlet 2 is clean.
