Description

Technical Field

[0001] The utility model relates to the technical field of river water intake, in particular to a return-type water intake sedimentation tank. Background Art

[0002] Rivers are common sources of water for people's domestic and irrigation use. Since rivers are usually located at a lower level, water pumps are generally required to pump water from higher places when taking water from rivers. However, there are also river sections in nature where the riverbed is higher than the ground on both sides. They are usually called suspended rivers or above-ground rivers. For water intake from suspended rivers, river water can usually be directly led out for use. Suspended rivers are generally formed because the silt carried by the river water has been accumulated for a long time, resulting in a high riverbed. The river water has a high sand content, and the sedimentation and treatment of the silt needs to be considered when taking water.

[0003] Therefore, how to design a water intake system that can conveniently realize sediment sedimentation treatment so that it can be better applied to suspended river water intake has become a problem to be considered by technical personnel in this field. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a return water intake sedimentation tank suitable for taking water from a suspended river and capable of conveniently realizing sediment sedimentation treatment.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A return-type water intake sedimentation tank is characterized in that it includes a river bank arranged along the river bank, and also includes four base banks arranged vertically connected to the river bank; a sedimentation area is formed between the two middle base banks, and the sedimentation area is provided with a number of partition banks which are staggered and vertically fixed on the two middle base banks, and a sedimentation channel for allowing the incoming water to flow in an S-shaped tortuous manner as a whole is formed between the partition banks; a water inlet connected to the water inlet end of the sedimentation channel is opened on the river bank, and a water inlet valve is arranged at the water inlet to connect with the river channel and form the water inlet end.

[0007] Furthermore, a water storage channel is formed between the two base dikes at the upstream end, an overflow outlet is provided at the water outlet of the sedimentation channel and connected to the water storage channel, and a water supply gate valve is provided at the water outlet of the water storage channel.

[0008] In this way, river water enters the sedimentation area from the water inlet valve, flows through the overall S-shaped sedimentation channel, and completes the gradual sedimentation of sediment to obtain clarified river water. The set water storage channel can make the clarified river water flow out from the overflow outlet at the outlet end of the sedimentation channel and accumulate in the water storage channel, which can better meet the demand for stable water discharge.

[0009] Furthermore, a water gate valve is provided at the overflow outlet, so that the overflow water outlet height can be conveniently adjusted.

[0010] Furthermore, a sand discharge channel is formed between the two base dikes at the downstream end; and on the base dike between the sand discharge channel and the sedimentation area, a sand discharge gate valve is provided corresponding to the sedimentation flow channel between each pair of adjacent partition dikes.

[0011] In this way, it is convenient to flush the sediment in the sedimentation channel into the sand discharge channel for discharge after opening the sand discharge gate valve.

[0012] Furthermore, on the base embankment between the water storage channel and the sedimentation area, a sand flushing gate valve is provided corresponding to the sedimentation flow channel between each pair of adjacent partition embankments.

[0013] In this way, when the sediment needs to be cleaned in the sedimentation area, the sand flushing gate valve can be opened to introduce the clean water accumulated in the water storage channel to backflow and flush the sedimentation channels, thereby achieving reverse sand flushing and flushing the sediment into the inner and outer sand discharge channels for discharge.

[0014] Furthermore, the sedimentation channel between each pair of adjacent dikes is inclined from high to low along the upstream end to the downstream end.

[0015] This makes it easier to use the clean water in the water storage channel to flush and clean the silt deposited in the sedimentation channel.

[0016] Furthermore, a drain pipe with a switch is installed at the bottom of the outermost dam at the end of the sand settling channel. This makes it convenient to drain the water in the sand settling area through the drain pipe when the water in the sand settling area needs to be drained out.

[0017] Furthermore, a sand scraping device is provided on the base embankment outside the sand discharge channel, and the sand scraping device includes a sand scraping plate arranged in the sand discharge channel along the width direction, the upper end of the sand scraping plate is higher than the base embankment and a support arm end extends to the base embankment, a roller is provided on the support arm end and is snap-fitted to the guide rail on the upper surface of the base embankment, a sand scraping power motor is also installed on the support arm end, a sand scraping gear is installed on the output shaft of the sand scraping power motor, and the sand scraping gear is engaged with a sand scraping rack arranged along the length direction of the base embankment.

[0018] In this way, the sand scraping power motor drives the sand scraping gear to rotate and cooperate with the sand scraping rack, which can drive the sand scraping plate to move horizontally along the sand discharge channel to scrape out the accumulated sand in the sand discharge channel, making it easier to clean the sand. During implementation, similar sand scraping devices are also correspondingly provided on each dike, making it easier to clean the sand in the sand settling channel.

[0019] Furthermore, the water inlet of the return water intake sedimentation tank is connected to the river channel through a floating object interception device, which is convenient for intercepting floating objects.

[0020] Furthermore, a water retaining dam is arranged outside the water inlet of the river bank, and a water diversion channel is formed between the water retaining dam and the river bank. The floating object interception device is arranged in the water diversion channel facing the water inlet of the river bank. This makes it more convenient to set up the floating object interception device and to introduce river water.

[0021] Furthermore, the floating object interception device includes a mounting frame, the two sides of which are supported and fixed on a floating body, the floating body floats on the water surface, the front end of the mounting frame is located below the water surface and is provided with a passive wheel arranged along the width direction of the water diversion channel, the rear end of the mounting frame is located above the water surface and is suspended with a driving wheel arranged along the width direction of the water diversion channel, and a conveyor belt is provided between the passive wheel and the driving wheel; an impeller is also installed in the middle position of the mounting frame, the impeller is arranged in the direction of the water flow and the lower part is immersed under the water surface, and the rotating shaft of the impeller is connected to the driving wheel through a transmission mechanism.

[0022] In this way, after the water flows into the water diversion channel, it is blocked by the conveyor belt, and then the water flow impacts the impeller to rotate, further driving the upper surface of the conveyor belt to be transported upward, lifting the floating objects that hit the conveyor belt upward and transporting them to the accumulation area at the downstream end of the floating object interception device, so that they can be transported out for centralized treatment, avoiding the floating objects from entering the water intake area. In this way, not only the power of water flow is used to realize the automatic cleaning of floating objects, but the device can also automatically float and adjust with the rise and fall of water level, ensuring the reliability and stability of the interception work.

[0023] Furthermore, the rotating shaft of the impeller is connected to a driving gear through a belt, the driving gear is meshed with a driven gear, and the driven gear is connected to the driving wheel through a belt.

[0024] In this way, the steering is achieved through a pair of gears and then the transmission is achieved through a belt, and the structure is simple, reliable and stable.

[0025] Furthermore, a plurality of interception protrusions are arranged in rows on the surface of the conveyor belt, so as to realize automatic interception and transmission of floating objects more conveniently.

[0026] Furthermore, a plurality of water leakage holes are arranged on the surface of the conveyor belt, so as to facilitate automatic water leakage in the process of intercepting and conveying floating objects.

[0027] Furthermore, a slide plate is arranged on the mounting frame behind the driving wheel, tilted downward and backward, so as to more conveniently intercept the sliding of floating objects.

[0028] Furthermore, a floating body is provided on each side of the front and rear ends of the mounting frame, so that the balance can be better ensured.

[0029] Furthermore, grooves are provided on the side walls of both sides of the water diversion channel corresponding to the floating bodies, and the floating bodies are installed in the grooves accordingly.

[0030] This effectively achieves the front and rear position limitation of the floating body, thereby achieving the overall position limitation of the floating object interception device.

[0031] In summary, the utility model has the advantages of being able to directly draw water from the river, facilitating sedimentation treatment, facilitating floating object interception treatment, etc., and is particularly suitable for drawing water from a suspended river.
