Description

Technical Field

[0001] This utility model relates to the field of water diversion, specifically to a water diversion system and a reservoir system. Background Technology

[0002] According to the principles of self-priming water pumps, their suction lift limit is less than 10m. Most self-priming water pumps on the market have a suction lift of around 6m, with some pumps equipped with vacuum devices in the suction pipe that can increase it to 8m. Therefore, when the depth of the storage tank exceeds 8m, the water in the tank cannot be fully utilized. Due to the insufficient suction lift of the pump, the depth of the tank cannot exceed the pump's suction lift range to effectively draw water. Therefore, to meet a certain water storage capacity, the only solution is to increase the area of ​​the storage tank, which will lead to increased land acquisition and engineering costs, resulting in low water diversion efficiency and high water diversion costs. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] In related technologies, the water diversion methods are as follows:

[0005] Method 1: Install a foot valve for priming. Limitations: The foot valve may leak, requiring manual priming; the suction lift is limited by the performance of the self-priming pump, typically not exceeding 6-8m.

[0006] Method 2: Use a priming cylinder or a sealed water tank to prime water. Limitations: prone to air leakage after repeated start-ups and shutdowns, reducing priming efficiency; not suitable for long and thick suction pipes; requires repeated priming and pump restarts.

[0007] Method 3: Using a water jet injector and a vacuum pump to draw water. Limitations: Water jet injectors require additional pressurized water equipment and are only suitable for small water pumps; vacuum pumps require additional equipment, increasing potential points of failure, maintenance work, and energy consumption.

[0008] Method 4: Use a self-priming water pump for priming. Limitations: Self-priming pumps have a limited suction lift, typically about 6m; they cannot be used for priming if the depth of the storage tank exceeds the suction lift.

[0009] This utility model aims to at least partially solve one of the technical problems in the related art.

[0010] Therefore, embodiments of this utility model propose a water diversion system with high water diversion efficiency and low water diversion cost.

[0012] The water intake system according to an embodiment of the present invention includes: a water intake component, which includes a suction pump, a suction pipe, and a bottom valve. The suction pump is adapted to be located outside the reservoir and at the bottom of the dam. The two ends of the suction pipe are respectively connected to the suction pipe and the bottom valve.

In the first state, the first solenoid valve is open to replenish water to the suction pipe, and in the second state, the first solenoid valve is closed to stop replenishing water to the suction pipe.

[0016] In some embodiments, the volume of the water tank is greater than the volume of the suction pipe.

[0017] In some embodiments, one end of the pipe is connected to the bottom of the water tank.

[0018] In some embodiments, the water intake system further includes a first pipe and a second pipe.

The water intake system has a third state and a fourth state. In the third state, the water in the water tank is lower than a first preset value. The other end of the second pipe is connected to the water tank so that water from the water pump flows into the water tank through the first pipe and the second pipe.

[0028] The water diversion system 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0029] like Figure 1 As shown, the water intake system 100 according to an embodiment of the present invention includes a water intake component 1 and a water replenishment component 2.

[0030] The water intake assembly includes a suction pump 11, a suction pipe 12, and a bottom valve 13. The suction pump 11 is suitable for being located outside the reservoir and at the bottom of the dam. Both ends of the suction pipe 12 are connected to the bottom valve 13, respectively. The bottom valve 13 is suitable for being located inside the reservoir so that the suction pump 11 can draw water from the reservoir through the suction pipe 12 and the bottom valve 13. Specifically, as... Figure 1 As shown, the suction pump 11 adopts a vertical multi-stage centrifugal pump structure and is installed on the bottom concrete base on the backwater side of the reservoir dam. The inlet of the suction pipe 12 is located inside the reservoir and is equipped with a foot valve 13, which prevents the water in the pipeline from flowing back into the reservoir when the suction pump 11 stops. This avoids energy loss caused by water backflow when the suction pump 11 is repeatedly started and stopped, while maintaining the continuity of the water column in the suction pipe 12. The outlet of the suction pipe 12 is connected to the inlet of the suction pump 11, so that the suction pump 11 can draw water from the reservoir through the suction pipe 12 and the foot valve 13.

[0031] The water replenishment component 2 is connected to the water suction pipe 12. The water replenishment component 2 is used to replenish water to the water suction pipe 12. The water intake system 100 has a first state and a second state. In the first state, the water suction pump 11 is closed, and the water replenishment component 2 is opened to replenish water to the water suction pipe 12 so that the water suction pipe 12 is filled with water to create a siphon effect. In the second state, the water replenishment component 2 is closed and the water suction pump 11 is opened so that the water suction pump 11 can draw water from the reservoir. Specifically, as shown in the figure... Figure 1 As shown, the outlet of the water replenishment component 2 is connected to the water suction pipe 12. The water replenishment component 2 can replenish water to the water suction pipe 12. Before the water intake component 1 starts water intake, the water replenishment component 2 is in the first state. The water replenishment component 2 is turned on and the water suction pump 11 is turned off. The water replenishment component 2 can replenish the water suction pipe 12 and the water suction pump 11, so that the water suction pipe 12 and the water suction pump 11 are filled with water, thereby causing the water suction pipe 12 to generate a siphon effect. The water in the reservoir is automatically sucked into the water suction pipe 12. When the water intake component 1 starts water intake, the water replenishment component 2 is turned off and the water suction pump 11 is turned on, so that the water in the water suction pipe 12 is sucked out by the water suction pump 11, thereby realizing low-energy continuous water intake.

[0032] The water diversion system 100 of this utility model embodiment is equipped with a water replenishment component 2. The water replenishment component 2 replenishes water to the water suction pipe 12 and the water suction pump 11 to generate a siphon effect in the water suction pipe 12. Water in the reservoir can be automatically drawn into the water suction pipe 12 through the water suction pipe 12, and then pumped into external water-using equipment by the water suction pump 11. This solves the problem of mismatch between the suction lift of the self-priming pump and the water depth of the reservoir. It can adapt to reservoir depths of more than 6m. Compared with related technologies, it does not require expanding the footprint of the water storage tank or manually filling the water suction pipe 12, thus improving the water diversion efficiency of the water diversion system 100 and reducing the water diversion cost.

[0033] In some embodiments, the water replenishment component 2 includes a water tank 21 and a pipe 22.

[0034] The water tank 21 is suitable for being located outside the reservoir and above the suction pipe 12. The water tank 21 is suitable for storing water. Both ends of the pipe 22 are connected to the water tank 21 and the suction pipe 12 respectively, so that the water tank 21 can replenish water to the suction pipe 12 through the pipe 22. Specifically, as... Figure 1 As shown, the water tank 21 can be installed on a concrete support pier on the backwater side of the reservoir dam, which is higher than the top of the suction pipe 12. The inlet of the pipe 22 can be connected to the bottom of the water tank 21. In the first state, the outlet of the pipe 22 is connected to the suction pipe 12, so that the water tank 21 supplies water to the suction pipe 12 through the pipe 22. In the second state, the outlet of the pipe 22 is disconnected from the suction pipe 12. Compared with the methods 2 and 3 in the related technologies, there is no need to consider the easy leakage of air after multiple start-ups and shutdowns, which would reduce the water diversion effect. There is also no need for additional pressure water equipment, which reduces the cost of using the water replenishment component 2.

[0035] In some embodiments, the water supply system 100 further includes a first solenoid valve 23, which is disposed within the pipe 22. In a first state, the first solenoid valve 23 is open to replenish water to the suction pipe 12; in a second state, the first solenoid valve 23 is closed to stop replenishing water to the suction pipe 12. Specifically, as... Figure 1 As shown, the first solenoid valve 23 can be a water inlet valve and is installed in the pipeline 22. In the first state, the first solenoid valve 23 is open, so that the water tank 21 replenishes water to the suction pipe 12 through the pipeline 22. In the second state, the first solenoid valve 23 is closed, so that the pipeline 22 is closed and the pipeline 22 no longer supplies water to the suction pipe 12.

[0036] In some embodiments, the volume of the water tank 21 is greater than the volume of the pipe 22 of the suction pipe 12. This is because when the water supply system 100 is first started or after a long period of shutdown, air accumulates in the suction pipe 12, creating an air resistance. To establish a continuous water column and trigger the siphon effect, the air in the pipe must be completely expelled and the pipe filled with water. If the volume of the water tank 21 is smaller than the volume of the suction pipe 12, a gas-liquid mixture will always exist in the suction pipe 12 during the water replenishment process. Therefore, a larger volume in the water tank 21 ensures that the water in the water tank 21 fills the entire suction pipe 12, thus guaranteeing the siphon effect of the suction pipe 12.

[0037] In some embodiments, one end of the pipe 22 is connected to the bottom of the water tank 21. Specifically, as shown in the figure... Figure 1 As shown, the inlet of pipe 22 is connected to the bottom of water tank 21, which can make full use of the gravitational potential energy of the water in water tank 21, so that the water in water tank 21 flows completely into water suction pipe 12.

[0038] In some embodiments, the water intake system 100 further includes a first pipe 3 and a second pipe 4. One end of the first pipe 3 is connected to a water pump 11 so that water flowing out of the water pump 11 flows into the first pipe 3. One end of the second pipe 4 is connected to the first pipe 3. The water intake system 100 has a third state and a fourth state. In the third state, the water level in the water tank 21 is lower than a first preset value, and the other end of the second pipe 4 is connected to the water tank 21 so that water pump 11 flows into the water tank 21 through the first pipe 3 and the second pipe 4. In the fourth state, the other end of the second pipe 4 is disconnected from the water tank 21. Specifically, as shown in... Figure 1 As shown, the third state is the water level maintenance mode. When the water level in the water tank 21 is lower than the first preset value (e.g., 20% of the total volume), the circulation water replenishment process is triggered, and a water circulation path is established from the water pump 11 to the first pipe 3, the second pipe 4, and the water tank 21. Water is replenished to the water tank 21 through the second pipe 4. The fourth state is the normal water intake mode, where the water is directly transported to the water user through the first pipe 3.

[0039] In some embodiments, the water intake system 100 further includes a float control valve 5 and a second solenoid valve 6. The float control valve 5 is disposed on and communicates with the second pipe 4, and the second solenoid valve 6 is disposed at the other end of the first pipe 3 and communicates with the other end of the first pipe 3. In a third state, the float control valve 5 is open and the second solenoid valve 6 is closed; in a fourth state, the float control valve 5 is closed and the second solenoid valve 6 is open. Specifically, as... Figure 1As shown, the float control valve 5 is located inside and connected to the second pipe 4, and the second solenoid valve 6 is a power switch valve located inside the second pipe 4 and at the right end of the connection point between the second pipe 4 and the first pipe 3. In the third state, the float control valve 5 is open and the second solenoid valve 6 is closed, so that the water in the suction pump 11 flows into the water tank 21. In the fourth state, the float control valve 5 is closed and the second solenoid valve 6 is open, so that the water in the suction pump 11 flows into the water-using end.

[0040] In some embodiments, the water intake system 100 further includes a float 7, which is disposed on the suction pipe 12 and adjacent to the bottom valve 13. The float 7 is used to drive the bottom valve 13 to float on the horizontal surface of the reservoir. Specifically, as Figure 1 As shown, the floating component 7 can be a float and is installed at the inlet end of the suction pipe 12. The floating component 7 drives the bottom valve 13 and the inlet of the suction pipe 12 to float on the horizontal surface of the reservoir through its buoyancy. This allows the suction pipe 12 to always draw water from the upper clear water area of ​​the reservoir, avoiding the draw of water from the bottom layer that may contain more sediment and impurities. This ensures the quality of the water taken, reduces the risk of the bottom valve 13 being blocked by bottom mud, and extends the service life of the bottom valve 13.

[0041] In some embodiments, the suction pipe 12 includes a first section 121 and a second section 122. The first section 121 is adapted to be located inside the reservoir, and a bottom valve 13 is located at the free end of the first section 121. The second section 122 is adapted to be located outside the reservoir, and at least a portion of the second section 122 is below the bottom of the reservoir. Specifically, as... Figure 1 As shown, the first section 121, the suction pipe 12, is located inside the reservoir. A bottom valve 13 is provided at the left end of the first section 121. The second section 122, the suction pipe 12, is located outside the reservoir, and the right end of the first section 121 is connected to the left end of the second pipe 4. Part or all of the second section 122 is lower than the bottom of the reservoir. This not only ensures the continuous siphon reaction in the suction pipe 12, but also prevents water from flowing back into the reservoir when the system stops. At the same time, it keeps the water column in the suction pipe 12 continuous, which facilitates quick restart next time.

[0042] The water intake system 100 of this embodiment mainly consists of two parts: the arrangement of equipment and the connection of pipelines. First, a self-priming pump 11 is placed at the bottom of the dam outside the reservoir. The suction pipe 12 at the inlet of the pump 11 extends along the dam surface into the water. A float 7 is used to float the suction pipe 12 on the reservoir surface for water intake. A bottom valve 13 is installed at the end of the suction pipe 12 to prevent water from flowing back into the reservoir. Next, a water tank 21 is placed at the top of the dam. A branch pipe from the outlet of the pump 11 connects to the top of the water tank 21. A float control valve 5 is installed at the inlet of the water tank 21. The bottom of the water tank 21 is connected to the first pipe 3 of the pump 11 via a second pipe 4. A second solenoid valve 6 is installed on the suction pipe 12. The second solenoid valve 6 can be remotely opened and closed, and is interlocked with the start and stop of the pump 11. Before the first water intake, the water tank 21 must be filled. During water intake, the first solenoid valve 23 is opened first. Water flows by gravity, filling the suction pump 11 and suction pipe 12. The suction pump 11 can then be started. After water intake, the water level in the tank 21 decreases, and the outlet branch pipe of the self-priming pump 11 and the float control valve 5 automatically replenish the tank 21. When the water level in the tank 21 reaches a certain level, the float control valve 5 closes, and water replenishment automatically stops. When the water level in the tank 21 decreases, the float control valve 5 opens, and water replenishment automatically resumes. A switch valve is installed at the outlet of the self-priming pump 11 to prevent water from flowing directly out of the first outlet pipe 3 during intake. After the suction pump 11 starts, the second solenoid valve 6 is opened to ensure normal operation of the suction pump 11. The suction pipe 12 uses a float 7 to float on the water surface, ensuring the intake of clean water from the upper layer of the reservoir. After the initial operation of the self-priming pump 11, subsequent water intake during production can be automatically completed by the plant's DCS before starting the suction pump 111.

[0043] The advantages of this water absorption system are as follows:

[0044] The suction pump 11 is arranged at the bottom outside the reservoir dam, which allows the self-priming pump to have a small suction head and still be able to draw water when the reservoir water level is low.

[0045] The volume of the water tank 21 needs to be larger than that of the suction pipe 12 so that it can fill the test pump and the suction pipe 12 during the first water intake. The water tank 21 is located on the top of the reservoir dam so that the suction pipe 12 and the suction pump 11 can be replenished with water by the weight of the water after the valve is opened.

[0046] The outlet of the suction pump 11 is connected to the water tank 21 via a second pipe 4, and the inlet of the water tank 21 is equipped with a float control valve 5. After the initial water intake, the water level in the water tank 21 decreases. After the suction pump 11 is turned on, water can be replenished to the water tank 21 through the branch pipe. When the water level in the water tank 21 reaches a certain level, the float control valve 5 closes, and the water tank 21 automatically stops replenishing water. When the water level in the water tank 21 decreases, the float control valve opens, and the water tank 21 automatically replenishes water. A bottom valve 13 is installed at the bottom of the suction pipe 12 to prevent water in the suction pipe 12 from flowing back into the reservoir during water intake; a switch valve is installed at the pump outlet to prevent water from flowing directly away from the outlet pipe 22 during water intake. The suction pipe 12 uses a float 7 to float on the water surface, ensuring that it draws clean water from the upper layer of the reservoir.

[0047] After the water pump 11 is replaced or repaired, there is no need to refill the water tank 21. The valve between the water tank 21 and the suction pipe 12 is opened via the plant's DCS. After the set priming time, the water pump 11 is started, the valve is closed, and the priming process ends.

[0049] The water diversion system 100 is any one of the water diversion systems 100 in the above embodiments.

[0051] The reservoir system 10 of this utility model embodiment is as follows:

[0052] The reservoir is 12m deep with an effective water level of approximately 10m. The self-priming pump 11 has a flow rate of 480m³ / h, a head of 30m, a suction lift of approximately 6m, and a suction pipe 12 of DN250. The pump 11 is positioned at the bottom of the dam outside the reservoir, while the water tank 21 is located at the top of the dam. A branch pipe (second pipe 4) from the outlet of the pump 11 connects to the water tank 21. A DN200 float control valve 5 is installed at the inlet of the water tank 21. A DN200 pipe at the bottom of the water tank 21 connects to the suction pipe of the pump 11, and an electric butterfly valve is installed on this pipe. This connection communicates with the system control station and is controlled by the plant's DCS. A bottom valve 13 of DN250 is installed at the bottom of the suction pipe 12 of the pump 11, and a floater 7 is used to keep the suction pipe 12 afloat on the water surface.

[0053] The water tank 21 must be filled with water for the first time. Before starting the water suction pump 11, open the water tank 21 to fill the water suction pump 11 and the suction pipe 12. Then start the water suction pump 11 and close the first solenoid valve 23. No manual intervention is required after normal operation.
