Description

Technical Field

[0001] The utility model belongs to the field of fluid transportation, and specifically relates to a water diversion cylinder and a water diversion device. Background Art

[0002] Water diversion cylinders are widely used, often in rural irrigation, aquaculture, and urban water use. During use, the cylinder must be installed above the water source. First, fill the cylinder with water. Once the pump is activated, negative pressure forms inside the cylinder as the water is pumped out. Water from the source rises along the diversion pipe until it enters the cylinder (when the negative pressure is sufficient), creating a continuous water supply. Currently, there's little systematic and comprehensive information on water diversion with diversion cylinders. Some sources simply assume that the larger the cylinder's volume, the better. This makes it difficult for users to gain a systematic and clear understanding of the diversion principles and processes, leading to illogical structures in some diversion cylinder devices and even difficulties in proper water diversion.

[0003] The prior art includes a technology titled "Water Drain Pump" and published as "CN200999732Y." This technology discloses a water drain pump consisting of a motor, pump body, pump shaft, and pump base. The pump body is mounted on the pump base, and the pump body is provided with a pump shaft, a water outlet, and a water inlet. The motor's output shaft is connected to the pump shaft. A water drain is located outside the pump body, and the pump base and pump body are both located within the drain. A water drain pipe is located at the top of the drain, and the water outlet of the pump body is connected to the side wall of the drain. Before starting the water drain pump, the drain is filled with water to the junction section of the drain pipe. After the pump is started, the water level in the drain drops, creating negative pressure within the drain, and water from the pool rises through the suction pipe. When the water level in the drain drops to the water inlet section of the pump body, the suction pipe is filled with water, and the water suction system enters operation. Clearly, this technology does not address the technical problem and solution of the present application. Utility Model Content

[0004] The present invention is designed to solve the above problems and aims to provide a water diversion device with a simple structure, stable operating performance and high system cavitation margin.

DETAILED DESCRIPTION

[0018] The following is a further detailed description of the specific implementation methods of the present invention through the description of the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0019] Figure 1 It is a structural schematic diagram of a water diversion cylinder and a water diversion device in an embodiment of the present utility model.

[0020] like Figure 1 As shown, the water diversion cylinder 10 provided by the present invention includes a water diversion pipe 11 and a water diversion cylinder body 12, and the water diversion cylinder body 12 includes a first cylinder 121 and a second cylinder 122. The first cylinder 121 is truncated cone-shaped, and the second cylinder 122 is cylindrical. The first cylinder 121 is arranged on the second cylinder 122. The structure of the water diversion cylinder body 12 can greatly reduce the volume of air remaining above the water diversion cylinder body after it is filled with water, thereby improving the water diversion performance. The water diversion pipe 11 is connected to the first cylinder 121. The utility model also provides a water diversion device, which includes the above-mentioned water diversion cylinder 10 and a water diversion pump 20. The water diversion pump 20 is provided with a water inlet pipe 21 and a water outlet pipe 22. The water inlet pipe 21 is connected to the water diversion cylinder 10, and the water outlet pipe 22 is connected to the water-using equipment. The water diversion process is completed by the water diversion pump 20. The water inlet pipe 21 extends into the cylinder and a 45° downward elbow 23 is welded at the pipe mouth. An exhaust valve 24 is installed under the check valve of the water pump outlet pipe 22, which helps to stabilize the operation of the system, reduce the negative pressure in the cylinder during water diversion, increase the cavitation margin of the device, and extend the service life of the water diversion pump.

[0021] One end of the water pipe 11 is connected to the first cylinder 121, and the other end of the water pipe 11 is provided with a water inlet 13, which is trumpet-shaped and immersed in the water source. A filter is provided inside the water inlet 13 to prevent foreign matter in the water source from entering the water cylinder 10.

[0022] The first cylinder 121 is provided with an overflow pipe 14. When water flows outward, it reminds the on-site operator that the water cylinder is full of water and the valve on the water injection pipe 16 should be closed immediately to avoid water waste.

[0023] Second cylinder 122 is provided with an exhaust pipe 15 equipped with a one-way valve, which allows air to escape only from inside water diversion cylinder body 12 to the atmosphere. This prevents ambient air from entering water diversion cylinder body 12. This creates a negative pressure within water diversion cylinder body 12, completing the water diversion process and improving structural reliability. Like overflow pipe 14, exhaust pipe 15 is responsible for exhausting air during the water filling process.

[0024] A water injection pipe 16 is provided on the second cylinder 122. The water injection pipe 16 can inject water into the water diversion cylinder body 12 for the water diversion pump 20 to extract. After the water diversion pump 20 extracts the injected water, negative pressure is generated in the water diversion cylinder body 12, thereby introducing water from the water source into the water diversion cylinder body 12 to complete the water diversion work.

[0025] When water is diverted by the water diversion cylinder and water diversion device provided by the present invention, water is filled into the water diversion cylinder body 12 through the water injection pipe 16, and the end of the water diversion pipe 11 away from the water diversion cylinder body 12 is immersed in the water source, and the water diversion pump 20 is started. The water diversion pump 20 draws the water injected into the cylinder body, so that negative pressure is generated in the water diversion cylinder body 12, and the water source water continuously enters the water diversion cylinder body 12, completing the water diversion process.

[0026] Functions and Effects of the Embodiments

[0027] The water diversion cylinder 10 provided by the present invention includes a water diversion pipe 11 and a water diversion cylinder body 12. The water diversion cylinder body 12 includes a first cylinder 121 and a second cylinder 122. The first cylinder 121 is designed as a truncated cone and is placed on the second cylinder 122. This can significantly reduce the volume of air remaining in the cylinder after the water diversion cylinder body 12 is filled with water. According to the water diversion principle of the water diversion cylinder, the volume of the water diversion cylinder can be greatly reduced, the height of the water diversion cylinder can be appropriately reduced, and the height difference between the cylinder water inlet and the water source liquid level is correspondingly reduced. An exhaust pipe 15 is added to the second cylinder 122 to help exhaust air in corners. The water diversion pipe 11 is connected to the first cylinder 121, and the water diversion port (13) at the end of the water diversion pipe is trumpet-shaped. The present invention also provides a water diversion device, comprising the aforementioned water diversion cylinder 10 and a water diversion pump 20. The water diversion pump 20 is provided with an inlet pipe 21 and an outlet pipe 22. The inlet pipe 21 is connected to the water diversion cylinder 10, extending into the cylinder body and having a 45° elbow 23 welded to the pipe opening to reduce the chance of the water pump inhaling air. An exhaust valve 24 is installed below the check valve of the water pump outlet pipe 22 to exhaust air from the water pump outlet pipe before starting the pump. The height of the cylinder water diversion port mentioned above is lowered, the first cylinder body 121 is designed as a frustum, the second cylinder body 122 is equipped with an exhaust pipe 15, the water diversion port 13 is trumpet-shaped, the inlet pipe 21 extends into the cylinder body and has a 45° elbow 23 welded to the pipe opening facing downward, and the exhaust valve 24 is installed below the check valve of the water pump outlet pipe 22. All of these contribute to stable system operation, reduce negative pressure within the cylinder body during water diversion, improve the cavitation margin of the device, and extend the service life of the water diversion pump.

[0028] The water diversion cylinder and water diversion device provided by this utility model divide the water diversion cylinder into two parts, significantly reducing the volume of air remaining in the cylinder after the cylinder is filled with water. This reduces the cylinder volume and the height difference between the cylinder water inlet and the water source liquid level. The design of the water diversion pipe and the water pump inlet and outlet pipes further reduces the negative pressure in the cylinder during water diversion, maximizes the cavitation margin of the device, and extends the service life of the water diversion pump.
