Description

Technical Field

[0001] This utility model relates to the field of irrigation device technology, specifically a diversion irrigation device for water conservancy projects. Background Technology

[0002] In the field of agricultural irrigation and water conservancy engineering, diversion devices are the core equipment for achieving efficient allocation of water resources. Traditional irrigation devices mostly adopt a single inlet design, and the water inlet channel relies on filter screens or simple grilles to intercept impurities. In rivers, canals with poor water quality or in flood-prone scenarios during the rainy season, impurities such as dead branches and fallen leaves may be wrapped around the surface of the filter screen, resulting in a reduction in water intake. Once the main inlet becomes blocked, it is necessary to stop the machine for maintenance, which directly affects irrigation efficiency and is inconvenient to use.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To solve the problems mentioned in the background art, the present invention is achieved through the following technical solution: a diversion irrigation device for water conservancy projects, including a base, a plurality of mounting holes on the base, a water pump installed on the base, a pumping structure installed at one end of the water pump inlet, and a water outlet pipe installed at one end of the water pump outlet.

[0005] The pumping structure includes a three-way connector, which is installed at one end of the water pump inlet, and two suction ends are symmetrically installed on the three-way connector;

[0006] Each of the inhalation ends includes a flow-blocking assembly mounted on a tee connector. One end of the flow-blocking assembly is connected to a connecting hose, and the other end of the connecting hose is connected to a bend pipe. An electric push rod is mounted on the bend pipe, and an electric turntable is mounted on the lower end of the electric push rod. The electric turntable is fixedly mounted on a base, and a flange is mounted on one end of the bend pipe. A filter screen is installed on the flange.

[0007] Preferably, the flow-stopping assembly includes a solenoid valve, which is mounted on a three-way connector. An electromagnetic flow meter is mounted on one end of the solenoid valve, and the connecting hose is mounted on one end of the electromagnetic flow meter.

[0008] Preferably, a fixing sleeve is provided between the telescopic end of the electric push rod and the bending tube.

[0009] Preferably, the flange and one end of the bent pipe are movably fitted with multiple bolts, and each bolt is movably fitted with a nut.

[0010] Preferably, the flange and the filter screen are an integral structure.

[0011] Preferably, a control panel is mounted on the base.

[0012] Beneficial effects

[0013] This utility model provides a diversion irrigation device for water conservancy projects. Compared with the prior art, it has the following advantages: by operating the water pump, two symmetrically arranged suction ends simultaneously draw irrigation water. When the filter screen in one suction end is blocked, resulting in low flow, the solenoid valve in that channel automatically closes. The electric push rod and the turntable work together to lift and rotate the filter screen to the maintenance position. At the same time, the other suction end continues to work, ensuring that the irrigation operation is not interrupted and guaranteeing irrigation efficiency. Attached Figure Description

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0019] To address the problems of traditional single-inlet irrigation devices that rely on filters or simple grilles to intercept impurities in rivers, canals, or flooded areas with poor water quality, debris such as fallen leaves and branches may accumulate on the filter surface, reducing water intake. Furthermore, if the main inlet becomes clogged, the system needs to be shut down for maintenance, directly impacting irrigation efficiency and causing inconvenience, this technical solution is designed. The detailed technical solution is as follows:

[0020] Please see Figure 1-2 A water diversion irrigation device for water conservancy projects includes a base 1, a plurality of mounting holes 14 on the base 1, a water pump 2 installed on the base 1, a pumping structure installed at one end of the water inlet of the water pump 2, and a water outlet pipe 15 installed at one end of the water outlet of the water pump 2.

[0021] It should be noted that multiple mounting holes 14 are used to insert fasteners, such as bolts 12 or screws, to fix the base 1 in the target position and connect the power supply to extend the water outlet pipe 15 into the position to be irrigated. The water pump 2 is used to provide power for the water pumping operation.

[0022] Specifically, the pumping structure includes a three-way connector 3, which is installed at one end of the water inlet of the water pump 2, and two suction ends are symmetrically installed on the three-way connector 3.

[0023] It should be noted that both suction ends extend into the water source, which can be a canal, river, or lake, etc.

[0024] Specifically, each suction end includes a flow-blocking component, which is installed on the three-way connector 3. A connecting hose 4 is installed at one end of the flow-blocking component, and a bending pipe 5 is installed at the other end of the connecting hose 4. An electric push rod 6 is installed on the bending pipe 5, and an electric turntable 7 is installed at the lower end of the electric push rod 6. The electric turntable 7 is fixedly installed on the base 1, and a flange 8 is installed at one end of the bending pipe 5. A filter screen 9 is installed on the flange 8.

[0025] Specifically, the flow-stopping assembly includes a solenoid valve 10, which is mounted on a three-way connector 3. An electromagnetic flow meter 11 is mounted on one end of the solenoid valve 10, and a connecting hose 4 is mounted on one end of the electromagnetic flow meter 11.

[0026] It should be noted that during water pumping, the electric push rod 6 is in the retracted state, and both sides of the filter screen cylinders 9 and one end of the bent pipe 5 extend into the water source. Driven by the water pump 2, water passes through the filter screen cylinders 9 and enters the bent pipe 5. As the water from the source passes through the filter screen cylinders 9, suspended solids and other impurities are intercepted, preventing them from entering the device and causing blockages or wear. The water in the bent pipe 5 flows sequentially through the connecting hose 4, the electromagnetic flowmeter 11, and the solenoid valve 10 into the three-way connector 3, and then is discharged from the outlet pipe 15 by the water pump 2, thus achieving irrigation. The electromagnetic flowmeter 11 is used to detect the water flow rate; if impurities accumulate on one side of the filter screen cylinder 9, the electromagnetic flowmeter 11 will detect a decrease in flow. When the flow rate is less than the set value, the solenoid valve 10 of this channel closes, the electric push rod 6 extends, causing the bending pipe 5 and the filter screen 9 to leave the water source, and the electric turntable 7 rotates, causing the bending pipe 5 and the filter screen 9 to rotate to one side of the device, making it convenient for staff to maintain the filter screen 9. If the electromagnetic flow meter 11 on the other side detects that the flow rate is normal at this time, the water suction work will proceed normally to ensure that the irrigation operation is not interrupted and to guarantee irrigation efficiency. The specific structure and working principle of the connecting hose 4 can refer to the high-flow telephone line water pipe in the existing technology. It can be stretched and bent to meet the lifting and rotation of the bending pipe 5. If the electromagnetic flow meters 11 on both sides detect that the flow rate is low at the same time, the machine will stop to check whether the water pump 2 is faulty.

[0027] As a preferred and further option, a fixing sleeve 16 is provided between the telescopic end of the electric push rod 6 and the bending tube 5;

[0028] As a preferred and further option, a plurality of bolts 12 are movably inserted into one end of the flange 8 and the bent pipe 5, and each bolt 12 is movably fitted with a nut 17 for connecting the flange 8 and the bent pipe 5, which facilitates disassembly and assembly.

[0029] As a preferred and further option, the flange 8 and the filter cylinder 9 are an integral structure. When maintaining the filter cylinder 9, the flange 8 and the filter cylinder 9 are removed from the bending pipe 5 as a whole, and then a new flange 8 and the filter cylinder 9 can be installed as a whole.

[0030] As a preferred and further option, a control panel 13 is installed on the base 1. The control panel 13 has a built-in microcontroller that can be programmed with software. By writing control programs, the device can be controlled. Since this is existing technology, it will not be described in detail here.

[0031] 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.
