Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a simple inverted siphon water intake device. Background Technology

[0002] Water intake projects are also widely used in water conservancy projects. Using a good water intake device can not only save manpower and material resources, but also achieve economic benefits. As we all know, the principle of inverted siphon water intake is to use the pressure difference of the water column to make the water rise and then flow to a lower place. Because the water surface at the pipe opening is subjected to different atmospheric pressures, the water will flow from the side with higher pressure to the side with lower pressure until the atmospheric pressure on both sides is equal, the water level in the container becomes the same height, and the water will stop flowing. Usually, reservoir water is diverted to water supply plants. Common methods include: using electric power to supply water, which will increase the operating cost of the water plant; or using water conveyance tunnels to supply water, which has poor water quality, increases the amount of chemicals added by the water plant, increases costs, and faces the problem of insufficient elevation difference.

[0003] In summary, most reservoirs use inverted siphons for water intake. However, inverted siphons require the siphon pipe to be filled with water. Furthermore, if the water plant is under maintenance or shut down, air will enter the siphon pipe, causing it to lose its siphon effect. When water is drawn again, the siphon pipe needs to be refilled, which is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a simple inverted siphon water intake device. By setting up a water intake pipe, a three-way pipe, a connecting pipe, an A check valve, and a submersible pump, it solves the problem that inverted siphon water intake requires filling the siphon pipe with water, and that if the water plant is under maintenance or stops operating, air will enter the siphon pipe, causing it to fail to achieve the siphon effect. The problem is that the siphon pipe needs to be refilled with water when water intake is resumed, which is quite inconvenient.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a simple inverted siphon water intake device, including a water intake pipe, a three-way pipe welded to the bottom end of the water intake pipe, a connecting pipe welded to the bottom end of the three-way pipe, a check valve A fixedly installed at the bottom end of the connecting pipe via flange A, and a submersible pump fixedly installed at the bottom end of the check valve A via flange B.

[0006] Preferably, a side pipe is welded to the surface of the tee pipe, an elbow is welded to one end of the side pipe, and a water suction pipe is welded to the bottom of the elbow.

[0007] Preferably, a B check valve is fixedly installed at the bottom end of the water suction pipe via a C flange, and a filter pipe is fixedly installed at the bottom end of the B check valve via a D flange.

[0008] Preferably, the filter tube has a partition mesh inside, and the connecting tube has a hanging bracket welded to its surface.

[0009] Preferably, the inside of the suspension bracket is wound with multiple steel ropes, and the top of the steel ropes is wound with a sleeve.

[0010] Preferably, a float is fixedly installed inside the frame, and a reflective warning sign is provided on the upper surface of the frame.

[0011] This utility model provides a simple inverted siphon water intake device, which has the following beneficial effects:

[0012] This equipment utilizes the siphon principle. First, a float pulls the device to a position 2-3 meters below the water surface, allowing it to access the optimal water source from the reservoir. A generator or existing power source is then connected to a submersible pump. By starting the submersible pump, the equipment is filled with water. After stopping the pump, water from the reservoir is drawn from the filter pipe, achieving the siphon principle. The water supply pipeline continues to supply water normally. When used in conjunction with the float, this equipment can obtain relatively high-quality water from the reservoir. Compared to electric water extraction, it significantly reduces the investment in water extraction projects. If air is present in the pipeline, preventing the siphon effect from being achieved, simply restarting the submersible pump will resolve the issue. The operation is convenient, reducing the workload of personnel during subsequent water filling and improving water extraction efficiency. Attached Figure Description

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a simple inverted siphon water intake device, including a water intake pipe 1. The top of the water intake pipe 1 is also equipped with a flange, which can be connected to a pipeline by bolts. Water in the reservoir is drawn to a lower position through the siphon effect. A tee pipe 2 is welded to the bottom end of the water intake pipe 1, and a connecting pipe 3 is welded to the bottom end of the tee pipe 2. A check valve 4 is fixedly installed at the bottom end of the connecting pipe 3 through flange A. A submersible pump 5 is fixedly installed at the bottom end of the check valve 4 through flange B. Water can be injected into the pipeline connected to this device through the submersible pump 5. After the water injection is completed, the pump is closed. Water is continuously output through the pipeline through the siphon effect. The check valve 4 prevents the internal water from flowing back into the reservoir.

[0023] A side pipe 6 is welded to the surface of the three-way pipe 2. An elbow 7 is welded to one end of the side pipe 6. A suction pipe 8 is welded to the bottom of the elbow 7. Water can flow into the side pipe 6 and the suction pipe 8 simultaneously through the injection of water by the submersible pump 5.

[0024] The bottom end of the suction pipe 8 is fixedly installed with a B check valve 9 via a C flange. The bottom end of the B check valve 9 is fixedly installed with a D flange. Under the action of the B check valve 9, the water injected into the equipment by the submersible pump 5 is prevented from being discharged into the reservoir through the filter pipe 10.

[0025] The filter tube 10 is equipped with a partition 11 inside to prevent large foreign matter from flowing into the tube. The surface of the connecting tube 3 is welded with a hanger 12.

[0026] Multiple steel cables 13 are wound inside the hanging base 12. The steel cables 13 are made of 6.2mm diameter steel wire rope and are about 3-5m long. A frame 14 is wound around the top of the steel cables 13. A float 15 is fixedly installed inside the frame 14. The float 15 is a hollow float made of polyethylene. A reflective warning sign 16 is provided on the upper surface of the frame 14. The float 15 floats on the water surface, allowing the equipment at the bottom to draw water at a depth of 2-3m in the reservoir, so that the equipment can draw water from the reservoir's optimal water source. At the same time, the reflective warning sign 16 prevents non-staff members from touching the equipment and makes it easy for staff to quickly spot the equipment.

[0027] This equipment uses multiple flanges to connect the various components. All flanges are fixed with hex bolts and hex nuts, and sealing rings are installed at the connection points to prevent internal water leakage that could cause equipment failure.

[0028] Specifically, when this simple inverted siphon water extraction device is in operation / use: This equipment utilizes the siphon principle. First, the float 15 is used to pull the device to a position 2-3m below the water surface, allowing the device to obtain the best water source from the reservoir. A generator or existing power source is used to connect the submersible pump 5. By starting the submersible pump 5, the device is filled with water. Then, the submersible pump 5 is stopped, and water from the reservoir will be drawn from the filter pipe 10, achieving the siphon principle. The water supply pipeline will then supply water normally. This equipment, used in conjunction with the float 15, can obtain relatively high-quality water from the reservoir. Compared with electric water extraction, it greatly saves on the investment in water extraction projects. If air is present in the pipeline and the siphon effect is not achieved, simply restarting the submersible pump 5 will solve the problem. The operation is convenient, reducing the workload of personnel in subsequent water filling and improving water extraction efficiency.

[0029] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
