Description

Technical Field

[0001] This application relates to the technical field of pumping stations, and in particular to an agricultural irrigation pumping station. Background Technology

[0002] Pumping stations, as core water conservancy facilities for farmland irrigation, are mainly responsible for drawing water from natural water sources such as rivers, ditches, and ponds to irrigation canals for farmland, providing stable irrigation water for farmland.

[0003] In practical applications, aquatic plants such as water hyacinths and weeds often float in water sources around farmland, along with household garbage, gravel, silt, and other debris. These plants and debris can easily enter the pumping pipes during the pumping process, causing blockages and interruptions in pumping. In severe cases, they can also damage critical components such as the pump impeller. Regular water outages are typically required to clean the pipes, resulting in high overall maintenance costs. Therefore, there is room for improvement. Utility Model Content

[0004] In order to limit the entry of river vegetation and debris into the pumping pipes of the pumping station during the pumping process, this application provides a farmland water conservancy pumping station.

[0005] This application provides a farmland irrigation pumping station, which adopts the following technical solution: A farmland irrigation pumping station includes a pump house and an interception structure; The pump room is equipped with a water pump, and the water pump is connected to an inlet pipe and an outlet pipe respectively. The interception structure includes an inlet pool located on one side of the river embankment. The inlet pool is positioned above the river water level. An inlet is provided on the side of the inlet pool away from the river embankment. A debris-blocking mesh is provided in the inlet pool corresponding to the inlet, and the debris-blocking mesh covers the inlet. The end of the inlet pipe away from the water pump extends into the inlet pool. An intercepting net is installed at the end of the inlet pipe located in the inlet pool. The mesh size of the intercepting net is smaller than that of the debris-blocking mesh.

[0006] By adopting the above technical solution, when river water enters the inlet pool, it can first pass through the debris-blocking screen to intercept larger debris such as water hyacinths, weeds, and larger domestic waste, thus initially purifying the water flow. Subsequently, when the water flow entering the inlet pool is pumped by the water pump, the intercepting net at the end of the inlet pipe further intercepts smaller debris such as gravel and fine silt that were not filtered by the debris-blocking screen, effectively reducing the amount of debris entering the water pump and inlet pipe, reducing the risk of pipe blockage and water pump damage. Compared with traditional treatment methods, there is no need to maintain the inlet pipe regularly, effectively reducing maintenance costs.

[0007] Preferably, a support is provided at the bottom of the water inlet pool, and the support is connected and fixed to the base of the river embankment through pre-embedded parts.

[0008] By adopting the above technical solution, the water intake pool is fixed to the bottom of the river embankment using pre-embedded parts, which effectively limits the displacement of the water intake pool caused by the scouring of the river water.

[0009] Preferably, the inlet has an opening at the top, and there are snap-fit ​​grooves on both sides of the inlet. The snap-fit ​​grooves have openings at the top, and the debris screen plate is slidably inserted into the snap-fit ​​grooves on both sides of the inlet.

[0010] By adopting the above technical solution, when the debris barrier needs to be cleaned or replaced due to blockage, the operator can directly pull the debris barrier upward from the top of the slot, which facilitates quick cleaning or replacement of the debris barrier.

[0011] Preferably, it also includes a support structure, which includes a plurality of anchor blocks. The anchor blocks are evenly distributed on the ground and the surface of the river embankment. The anchor blocks are located below the water inlet pipe. A limiting groove is opened on the surface of the anchor blocks corresponding to the water inlet pipe, and the water inlet pipe is embedded in the limiting groove.

[0012] By adopting the above technical solution, multiple anchor blocks are used to form multi-point support for the water inlet pipe, which helps to reduce the downward bending deformation of the water inlet pipe under stress. At the same time, the limiting groove on the anchor blocks is used to limit the water inlet pipe, which helps to reduce the vibration displacement of the water inlet pipe due to the impact of water flow during the pumping process.

[0013] Preferably, each of the piers is provided with a limiting clamp, which is embedded in the surface of the water inlet pipe and both ends of the limiting clamp are fixed to the pier.

[0014] By adopting the above technical solution and using the limiting clamp to further limit and fix the water inlet pipe, it is beneficial to fix the water inlet pipe more stably on the town pier.

[0015] Preferably, a flexible pad is laid in the limiting groove, and the water inlet pipe abuts against the flexible pad.

[0016] By adopting the above technical solution, when the water inlet pipe vibrates due to pumping, a flexible pad can be used to absorb the vibration, thereby buffering and reducing the friction and wear between the surface of the water inlet pipe and the pier.

[0017] Preferably, the floor inside the pump room is provided with a raised platform, and the water pump is installed on the raised platform.

[0018] By adopting the above technical solution, the water pump is raised off the pump room floor using a raised platform. This effectively prevents water from immersing the pump's motor, wiring, and other critical components when rainwater enters the pump room and causes water accumulation, thus reducing the likelihood of short-circuit failures due to moisture.

[0019] Preferably, the debris-blocking mesh is provided in two locations, and the two locations are evenly distributed in a direction away from the river embankment.

[0020] By adopting the above technical solution, the two debris-blocking screens serve as backups for each other. When cleaning the debris-blocking screens, one screen can be retained to ensure that the water inlet pool maintains its interception function and restricts debris from entering the water inlet pool through the inlet.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. When river water enters the inlet pool, debris carried by the river water can be intercepted by the debris screen and the interception net at the end of the inlet pipe, thus preventing debris from entering the pump and inlet pipe.

[0022] 2. Connecting the intake pool support to the river embankment through pre-embedded parts helps improve the overall stability of the intake pool and limits the displacement of the intake pool due to river scouring.

[0023] 3. By inserting the debris screen into the grooves on both sides of the water inlet, the debris screen can be detachably installed at the water inlet, making it convenient to disassemble and replace the debris screen after it becomes clogged. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses a farmland irrigation pumping station, as shown in the embodiments below. Figure 1 and Figure 2 It includes pump house 1, interception structure and support structure.

[0032] Reference Figure 1 and Figure 2 Pump station 1 is located on the ground near the river channel. Pump station 1 contains a water pump 11 and a power supply box, which supplies power to the water pump 11. The water pump 11 has an inlet pipe 111 and an outlet pipe 112 connected to its inlet and outlet ends, respectively. The interception structure includes an inlet pool 2, located within the river channel and near the river embankment 4. An inlet 20 is located on the side of the inlet pool 2 away from the river embankment 4, and a debris-blocking mesh 21 is installed at the inlet 20, covering it. The end of the inlet pipe 111 away from the water pump 11 extends to the bottom of the inlet pool 2. The debris-blocking mesh 21 at the inlet 20 of the inlet pool 2 intercepts aquatic plants, garbage, and other debris carried by the river water, effectively preventing debris from entering the inlet pipe 111 and causing blockage.

[0033] Reference Figure 1 and Figure 2 Pump house 1 is constructed of concrete brick masonry. A foundation 12 structural layer is provided at the bottom of pump house 1 to improve its overall stability. Specifically, the foundation 12 structural layer includes a stone chip cushion layer and a reinforced concrete layer distributed from bottom to top. Through-wall pipes are pre-embedded in the walls of pump house 1 corresponding to the inlet pipe 111 and outlet pipe 112, allowing the inlet pipe 111 and outlet pipe 112 to pass through the walls of pump house 1.

[0034] Reference Figure 1 and Figure 2The top wall of pump house 1 has several light-transmitting and ventilation openings 13, which facilitate air circulation between the inside and outside of pump house 1 and ensure that the interior of pump house 1 remains dry. A raised platform 10 is poured into the floor of pump house 1, and the water pump 11 and power supply box are installed on top of the raised platform. The raised platform 10 elevates the water pump 11 and power supply box off the ground, effectively preventing water from accumulating inside the pump house 1 due to rainwater intrusion and avoiding water damage to critical components such as the motor and wiring of the water pump 11, thus reducing the possibility of short-circuit failures caused by moisture. The roof of pump house 1 is higher in the middle and lower around the edges, which facilitates roof drainage and reduces rainwater accumulation on the roof of pump house 1.

[0035] Reference Figure 1 and Figure 3 The end of the inlet pipe 111 furthest from the pump 11 extends into the inlet pool 2. An intercepting net 113 is installed at the end of the inlet pipe 111 located within the inlet pool 2. The mesh size of the intercepting net 113 is smaller than that of the debris-blocking mesh 21. The intercepting net 113 is made of metal wire mesh. The intercepting net 113 at the end of the inlet pipe 111 further intercepts smaller debris such as gravel and fine silt that are not filtered by the debris-blocking mesh 21, effectively reducing the amount of debris entering the pump 11 and the inlet pipe 111.

[0036] The interception net 113 and the inlet pipe 111 are connected and fixed at one end by a flange structure, which facilitates the disassembly and replacement of the interception net 113 if it is damaged.

[0037] Reference Figure 1 and Figure 2 The intake pool 2 is entirely located on the base of the river embankment 4, and a support 22 is integrally formed at the bottom of the intake pool 2. The support 22 is connected and fixed to the base of the river embankment 4 through embedded parts, which helps to improve the integrity of the connection between the intake pool 2 and the river embankment 4 and limits the displacement of the intake pool 2 due to water flow impact. Specifically, the embedded parts include embedded sleeves and embedded steel bars, which are respectively embedded on the opposite side of the base of the river embankment 4 and the support 22, and the embedded steel bars and embedded sleeves are interlocked.

[0038] Reference Figure 1 and Figure 2 The inlet 20 has an opening at the top, and there are snap-fit ​​grooves 201 on both sides of the inlet 20. The snap-fit ​​grooves 201 have openings at the top, and the debris-blocking mesh plate 21 is slidably inserted into the snap-fit ​​grooves 201 on both sides of the inlet 20. When the debris-blocking mesh plate 21 needs to be cleaned or replaced due to a large amount of debris blockage, it can be pulled out directly from the top of the snap-fit ​​groove 201, making it easy to disassemble and replace the debris-blocking mesh plate 21.

[0039] In other embodiments, brackets are provided at both ends of the top of the inlet 20, and a winch is installed on the top of the brackets corresponding to the debris screen 21. The winch is connected to the top of the debris screen 21. When cleaning the debris screen later, the debris screen can be lifted out with the help of the winch, which facilitates the cleaning of the debris screen.

[0040] Reference Figure 1 and Figure 4 The supporting structure includes several anchor blocks 3, which are specifically reinforced concrete structures. These anchor blocks 3 are evenly distributed on the ground and the surface of the river embankment 4. The anchor blocks 3 located on the river embankment 4 are connected and fixed to the embankment 4 via embedded parts to ensure the connection strength between the anchor blocks 3 and the river. The anchor blocks 3 are located below the inlet pipe 111. A limiting groove 30 is formed on the surface of the anchor block 3 corresponding to the inlet pipe 111. A flexible pad 301, specifically a rubber pad with good elasticity and shock absorption performance, is glued and fixed within the limiting groove 30. The inlet pipe 111 is embedded in the limiting groove 30 and abuts against the flexible pad 301. The limiting groove 30 limits the movement of the inlet pipe 111; simultaneously, the flexible pad 301 absorbs vibration, buffering and reducing shock absorption, thus minimizing friction and wear between the surface of the inlet pipe 111 and the anchor blocks 3.

[0041] Reference Figure 1 and Figure 4 Each of the piers 3 is also equipped with a limiting clamp 31, which is embedded in the surface of the water inlet pipe 111. Both ends of the limiting clamp 31 are welded with connecting ear plates, which are fixed to the pier 3 by expansion bolts. The pier 3 is used to further limit and fix the water inlet pipe 111, so that the water inlet pipe 111 is more firmly fixed on the pier 3.

[0042] The implementation principle of this embodiment is as follows: When the water pump 11 inside the pump house 1 draws water from the river, the sewage discharge screen at the inlet 20 of the inlet pool 2, together with the intercepting net at the end of the inlet pipe 111, intercepts plants, garbage, and other debris in the river, preventing debris from entering the inlet pipe 111 along with the river water. This effectively reduces the risk of pipe blockage and damage to the water pump 11. Furthermore, it eliminates the need for regular manual dredging of the inlet pipe 111, reducing maintenance costs. The use of a support structure to support and limit the entire inlet pipe 111 helps reduce damage caused by vibration and displacement.

[0043] Example 2 The difference between Example 2 and Example 1 is that: Reference Figure 1 and Figure 5In this embodiment, two debris-blocking net panels 21 are provided, and the two debris-blocking net panels 21 are distributed in sequence in the direction away from the river embankment 4. With the provision of two debris-blocking net panels 21, when cleaning the debris-blocking net panels 21 in the future, after one debris-blocking net panel 21 is removed and cleaned, the other debris-blocking net panel 21 can continue to intercept debris in the river, avoiding the situation where debris enters the water inlet pool 2 through the water inlet 20 due to the removal of the debris-blocking net panel 21.

[0044] A submersible pump 23 is also installed at the bottom of the inlet pool 2. The outlet of the submersible pump 23 extends to the outer side of the top of the inlet pool 2. When cleaning the inlet pool 2 later, the screen plate 21 can be replaced with a solid steel plate to temporarily block the inlet 20 of the inlet pool 2. At the same time, the submersible pump 23 is used to pump out the river water inside the inlet pool 2, which makes it easier to clean the inside of the inlet pool 2 and the intercepting net 113 located at the end of the inlet pipe 111.

[0045] The implementation principle of Example 2 is similar to that of Example 1, so it will not be described again.

[0046] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
