Description

Technical Field

[0001] The invention relates to a surface water intake device, belonging to the technical field of water conservancy and hydropower. Background Art

[0002] The vast stagnant waters created by hydropower construction, influenced by factors such as solar radiation and the physical and chemical properties of water, create an aquatic environment completely different from that of natural rivers. Water temperatures within hydropower project reservoirs are typically stratified by depth. Traditional bottom-water extraction methods cause large amounts of low-temperature water to flow downstream, lowering the water temperature downstream. Irrigation with low-temperature water can affect crop growth and yields. Furthermore, this low-temperature water can inhibit the growth and reproduction of aquatic organisms and affect fish food. Because the water temperature differs from that of natural river channels, the low-temperature water must travel a considerable distance to return to natural channel conditions, disrupting the habitats of thermophilic fish and altering the river sections and times where fish breed, impacting their reproduction, migration, and foraging environments. Therefore, surface water is often drawn from intakes at major water sources, such as large reservoirs, to ensure consistent water temperature and oxygen content.

[0003] For example, Chinese patent document CN111945824A discloses a surface water intake device that automatically rises and falls with the water level, including a water intake pipe and a concrete fixed pile arranged on one side of the water intake pipe; the water intake pipe is divided into an upper half and a lower half, the upper half of the water intake pipe is slidably connected to the lower half of the water intake pipe via a sealing ring; the lower half of the water intake pipe is connected to the concrete fixed pile via a second nut, and the upper half of the water intake pipe is slidably connected to the concrete fixed pile via an adjustable rubber inflatable cylinder and a concrete counterweight. Under the dynamic balance of the adjustable rubber inflatable cylinder and the concrete counterweight, the position of the water inlet automatically moves up and down as the water level in the reservoir rises, ensuring that the water inlet is always constant at a certain distance below the water surface. The water entering the water intake pipe is high-temperature surface water, avoiding the adverse effects of low-temperature water leakage on agricultural production in the irrigation area.

[0004] However, the water inlet of the surface water intake device is always kept at a certain distance below the water surface, and its flexibility of use is poor. In addition, the surface water is relatively greatly affected by natural factors, reservoir operation factors, geographical and climatic factors, etc., resulting in the temperature of the water obtained by the surface water intake device not necessarily being able to meet the growth and reproduction needs of crops, fish and aquatic organisms downstream of the dam.

[0014] The driven transmission assembly includes a driven shaft, and driven sprockets are provided at both ends of the driven shaft, and the driven sprockets at both ends of the driven shaft are connected to the two chains in a one-to-one correspondence.

[0015] The support and limit component includes a plurality of support and limit assemblies arranged side by side, and the support and limit assemblies include a connecting rod, the two ends of the connecting rod are connected to the chain plates on the two chains one by one, and rollers are movably provided at both ends of the connecting rod, and the rollers at both ends of the connecting rod are located one by one in the U-shaped grooves on the two U-shaped seats.

[0016] The water temperature and water level detection component is a vertical multi-point temperature chain monitoring system, and the vertical multi-point temperature chain monitoring system is electrically connected to the controller.

[0017] The water surface detection component includes a radar level gauge, which is installed on the top of the water reservoir through a support plate and is electrically connected to the controller.

[0018] It also includes a water sealing mechanism, which includes an inflatable rubber sealing strip A, two inflatable rubber sealing strips B and an air pump. The inflatable rubber sealing strip A is arranged on the inner wall of the water intake tower on the side close to the water reservoir, and the top surface elevation of the inflatable rubber sealing strip A is consistent with the bottom surface elevation of the water reservoir.

[0021] 2. Since surface water is relatively greatly affected by natural factors, reservoir operation factors, geographical and climatic factors, etc., the temperature of surface water will fluctuate in real time. For this reason, the present invention is guided by water temperature and will discharge all or part of the water at a temperature that meets the growth and reproduction requirements of crops, fish and aquatic organisms downstream of the dam to the downstream of the dam in real time, while taking into account the discharge volume control of the water intake device. Specifically, when the water demand downstream of the dam is large, the water intake device will discharge all the water that meets the water temperature requirements to the downstream of the dam (that is, the right end of the flexible baffle moves to the target temperature sensor), and when the water demand downstream of the dam is small, the water intake device will discharge part of the water that meets the water temperature requirements to the downstream of the dam (that is, the right end of the flexible baffle moves to a certain distance above the target temperature sensor).

[0022] 3. For the straight section on the right side of the U-shaped notch, the gap between the flexible baffle and the right side wall of the U-shaped notch is sealed by the inflatable rubber sealing strip B to prevent water on the right side of the flexible baffle from flowing into the water intake tower through the gap during the water intake process; the gap between the flexible baffle and the bottom of the water tank is sealed by the inflatable rubber sealing strip A to prevent water on the right side of the flexible baffle from flowing into the water intake tower through the gap, thereby ensuring the water intake effect of the device.

[0030] like Figures 1 to 5 As shown, a surface water intake device described in the present invention includes a water intake tower 1, a water intake depth control mechanism, a flexible baffle 14 and a controller. The top of the water intake tower 1 is provided with an equipment warehouse 4, and one side of the water intake tower 1 is provided with a water reservoir 12. The water reservoir 12 is connected to the interior of the water intake tower 1 through multiple water outlets 15, and multiple water inlets 16 are opened on the water reservoir 12. A water temperature and water level detection component 13 is provided in the water reservoir 12, and a water surface detection component is provided on the top of the water reservoir 12. The water intake depth control mechanism is provided in the equipment warehouse 4 and the water intake tower 1, the flexible baffle 14 is located in the water intake tower 1 and is provided on the water intake depth control mechanism, and the controller is provided in the equipment warehouse 4. During use, the water temperature and water level detection component 13 detects the water temperature and water depth at multiple measuring points below the water surface along the water depth direction, and transmits the relevant water temperature and water depth information to the controller; the water surface detection component detects the distance from the water surface to the top of the water reservoir 12, and transmits the relevant distance information to the controller; based on the water temperature, water depth, and distance information, the controller controls the water intake depth control mechanism to drive the end of the flexible baffle 14 near the water reservoir 12 to move up or down a certain height, thereby ensuring in real time that the temperature of the water flowing into the water intake tower 1 after overflowing the flexible baffle 14 can meet the growth and reproduction needs of crops, fish, and aquatic organisms downstream of the dam, significantly improving the flexibility of the water intake device. The flexible baffle 14 refers to a rubber plate that can be normally bent.

[0031] The lower portion of the water intake tower 1 is provided with an outlet pipe 2, and a grating-type trash rack 24 is installed at the water inlet 16. During use, water that overflows the flexible baffle 14 and enters the water intake tower 1 is discharged downstream through the outlet pipe 2. The grating-type trash rack 24 is installed at the water inlet 16 to intercept floating objects and other impurities in the reservoir water, preventing these floating objects and other impurities from entering the water reservoir 12 and affecting the safe and stable operation of the water intake device.

[0032] Two U-shaped seats 21 are arranged side by side in the water intake tower 1 , and U-shaped notches 210 are opened face to face on the two U-shaped seats 21 .

[0033] The water intake depth control mechanism includes two chains 3, a drive assembly, two active transmission assemblies, four driven transmission assemblies and a support and limiting component. The two chains 3 are both ring-shaped, and a part of the chain 3 is located in the equipment warehouse 4, and the other part is located in the water intake tower 1. The drive assembly, the two active transmission assemblies and all the driven transmission assemblies are all arranged in the equipment warehouse 4. The two active transmission assemblies are connected to the drive assembly and are connected to the two chains 3 in a one-to-one transmission manner. All the driven transmission assemblies are arranged side by side and are connected to the two chains 3 in a transmission manner. The support and limiting component is located in the water intake tower 1, connected to the two chains 3, and movably connected to the U-shaped notches 210 on the two U-shaped seats 21;

[0034] The flexible baffle 14 is provided on the support and limit member. When in use, the support and limit member cooperates with the U-shaped notches 210 on the two U-shaped seats 21, so that the two chains 3 can be tensioned and operate normally. At the same time, the support and limit member connects the two chains 3, which can improve the operating stability of the two chains 3. Figure 1 As shown, in the initial state, the flexible baffle 14 is J-shaped, and its right end is located in the right straight section of the U-shaped notch 210, and the right end face of the flexible baffle 14 is coplanar with the top surface of the water reservoir 12. The controller records and saves the rotation angle of the main shaft of the servo motor 6 at this time; the left end of the flexible baffle 14 is located in the left straight section of the U-shaped notch 210, and the left end face of the flexible baffle 14 is much lower than the right end face, and slightly higher than the outlet pipe 2.

[0035] The drive assembly includes a reducer 7 and a servo motor 6 mounted on the reducer 7. The servo motor 6 is equipped with an encoder, which is in transmission connection with the reducer 7. The encoder, reducer 7, and servo motor 6 are all electrically connected to a controller. The servo motor 6 drives the two chains 3, facilitating accurate control of the ascent or descent height of the flexible baffle 14 at the end closest to the water reservoir 12.

[0036] The active transmission assembly includes a driving shaft, one end of which is connected to the output shaft of the reducer 7, and the other end is provided with a driving sprocket 8;

[0037] The driven transmission assembly includes a driven shaft 5, with driven sprockets at both ends of the driven shaft 5, and the driven sprockets at both ends of the driven shaft 5 are connected to the two chains 3 in a one-to-one correspondence. When in use, the driving shaft and the driven shaft are respectively installed in the equipment compartment 4 through seat bearings.

[0038] The support and limiter components include a plurality of support and limiter assemblies arranged side by side, each of which includes a connecting rod 19, the ends of which are connected to the chain plates 22 on the two chains 3 in a one-to-one correspondence. Furthermore, rollers 18 are rotatably provided at both ends of the connecting rod 19, and the rollers 18 at both ends of the connecting rod 19 are positioned in a one-to-one correspondence within the U-shaped notches 210 on the two U-shaped seats 21. When in use, the connecting rod 9 includes a supporting section and connecting sections provided at both ends of the supporting section. The supporting section has a square cross-section and is used to connect and support the flexible baffle 14. The connecting section is a screw, which facilitates the installation of the rollers 18 and facilitates connection with the chain plates 22.

[0039] The water temperature and water level detection assembly 13 is a vertical multi-point temperature chain monitoring system, which is electrically connected to the controller. During use, each measuring point of the vertical multi-point temperature chain monitoring system is equipped with not only temperature sensors but also liquid level sensors, enabling it to simultaneously detect water temperature and depth. This vertical multi-point temperature chain monitoring system can be purchased directly and is currently available, so its further description is omitted.

[0040] The water surface detection assembly includes a radar level gauge 10 , which is mounted on the top of a water reservoir 12 via a support plate 11 , and is electrically connected to a controller.

[0041] It also includes a water sealing mechanism, which includes an inflatable rubber sealing strip A17, two inflatable rubber sealing strips B23 and an air pump 9. The inflatable rubber sealing strip A17 is arranged on the inner wall of the water intake tower 1 on the side close to the water reservoir 12, and the top surface elevation of the inflatable rubber sealing strip A17 is consistent with the bottom surface elevation of the water reservoir 12. One side of the inflatable rubber sealing strip A17 rests on the flexible baffle 14, and the two ends rest on the two U-shaped seats 21 in a one-to-one correspondence. The two inflatable rubber sealing strips B23 are arranged on the two U-shaped seats 21 in a one-to-one correspondence. In the U-shaped notch 210 on the upper part, one side of the inflatable rubber sealing strip B23 is against the flexible baffle 14, and the inflatable rubber sealing strip B23 is arranged close to the end of the inflatable rubber sealing strip A17. The air pump 9 is arranged in the equipment compartment 4, and its air outlet is connected to the inflation main pipe, and the inflation main pipe is connected to the inflatable rubber sealing strip A17 and the inflatable rubber sealing strip B23 through the inflation branch pipe. The inflation main pipe is connected to the pressure relief pipe, and the pressure relief pipe is provided with an electric ball valve 20. The electric ball valve 20 and the air pump 9 are both electrically connected to the controller. When in use, the bottom elevation of the water reservoir 12 is consistent with the dead water level elevation of the reservoir. Figure 3 As shown, for the straight section on the right side of the U-shaped notch 210, the gap between the flexible baffle 14 and the right side wall of the U-shaped notch 210 is sealed by the inflatable rubber sealing strip B23 to prevent the water on the right side of the flexible baffle 14 from flowing into the water intake tower 1 through the gap during the water intake process; Figure 1 and Figure 3As shown, the gap between the flexible baffle 14 and the bottom of the water reservoir 12 is sealed by an inflatable rubber sealing strip A17 to prevent water on the right side of the flexible baffle 14 from flowing into the water intake tower 1 through the gap, thereby ensuring the water intake effect of the device.

[0042] The surface water intake device provided by the present invention has the following working principle:

[0043] The water intake temperature is preset on the controller, and the water temperature and water depth (referring to the distance from the measuring point to the water surface) of multiple measuring points below the water surface are detected along the water depth direction through the vertical multi-point temperature chain monitoring system, and the relevant water temperature and water depth information are transmitted to the controller; the radar level meter 10 is used to detect the distance from the water surface to the top of the water reservoir 12, and the relevant distance information is transmitted to the controller. Based on the water temperature, water depth and distance information, and combined with the current position of the right end face of the flexible baffle 14, the controller calculates the height that the right end face of the flexible baffle 14 needs to rise or fall. Specifically: Assuming that among all the temperature sensors whose actual detected water temperature is not less than the preset water intake temperature of the controller, the temperature sensor with the deepest water depth (i.e., the target temperature sensor, the same below) is at a distance of h from the water surface, the value of h can be obtained by detecting the liquid level sensor at the temperature sensor; Assuming that the distance from the water surface detected by the radar level meter 10 to the water reservoir 12 is L1; assuming that the distance from the right end face of the flexible baffle 14 to the top of the water reservoir 12 is L2, the value of L2 can be calculated by the accumulated rotation angle of the servo motor 6, combined with the transmission ratio between the servo motor 6 and the reducer 7, and the pitch circle of the driving sprocket 8 and other known quantities; then the height Δh that the right end face of the flexible baffle 14 needs to rise or fall is Δh = h + L1 - L2. When this value is positive, it indicates that the right end face of the flexible baffle 14 needs to fall, and when this value is negative, it indicates that the right end face of the flexible baffle 14 needs to rise.

[0044] Next, the controller activates the servo motor 6, which drives the two chains 3 via the reducer 7 and the driving sprocket 8. These chains, through the support and limiting components, drive the right end of the flexible baffle 14 to rise or fall to a certain height. When the servo motor 6 is turned off, the right end of the flexible baffle 14 moves to the target temperature sensor, or above it. This ensures that the temperature of the water flowing over the flexible baffle 14 into the water intake tower 1 is met in real time, meeting the growth and reproduction requirements of crops, fish, and aquatic life downstream of the dam, significantly improving the flexibility of the water intake device.

[0045] When the right end of the flexible baffle 14 is adjusted to the desired height, the air pump 9 inflates the inflatable rubber seal strips A7 and B23 through the main and branch air pipes to seal the gap between the flexible baffle 14 and the bottom of the water reservoir 12, and the gap between the flexible baffle 14 and the right side wall of the U-shaped notch 210. This prevents water on the right side of the flexible baffle 14 from flowing into the water intake tower 1 through these two gaps, thereby ensuring the water intake effect of the device. When the height of the right end of the flexible baffle 14 needs to be adjusted again, the electric ball valve 20 is first opened to deflate the inflatable rubber seal strips A7 and B23, so that the height of the right end of the flexible baffle 14 can be flexibly adjusted up and down.
