Description

Technical Field

[0001] This utility model belongs to the field of fertilization and irrigation equipment, and in particular relates to a float-type water pump for lifting fertilization and irrigation pumping stations. Background Technology

[0002] The pontoon + pumping station water intake technology is used to draw water from sources such as rivers, lakes, and reservoirs. It offers advantages such as flexibility, efficiency, and adaptability to water level changes. Its basic principle is to use the buoyancy of the pontoons to float the pumping station or related water intake equipment on the water surface, allowing the water intake to rise and fall with the water level, always remaining at a certain position below the water surface, thus ensuring a stable water intake. The pumps in the pumping station draw water from the intake near the pontoons through pipelines and then transport the water to where it is needed, such as irrigation systems.

[0003] Currently, irrigation systems using pontoons and pump stations typically employ pontoons made of high-strength, corrosion-resistant materials, such as high-density polyethylene. The pump station includes water pumps, motors, valves, pipelines, and control systems. The water pump is the core equipment, and appropriate pump types, such as submersible pumps, axial flow pumps, and centrifugal pumps, are selected according to actual needs to meet different flow rate and head requirements. For example, existing patents CN106973611A discloses an irrigation and filtration system for returning water to the field, CN114451258A discloses a floating water intake integrated device and its usage method for surface water irrigation, and CN220383852U discloses an intelligent irrigation system for the ecological restoration zone of the drawdown zone of a pumped storage power station. Among them, the floats disclosed in CN220383852U adopt a long-axis type, double float design, and the supporting surface and stress surface formed by it are more susceptible to the overturning force of the water surface. Furthermore, the connection reliability and connection life of the connecting components will also be affected to a certain extent. Moreover, many devices lack a flexible connection design between the float and the pump station, so the probability of cracks and deformation in the water intake pipe increases, affecting the performance of the water intake system.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Examples, such as Figures 1-8As shown, this utility model provides a float-type water pump lifting fertilization irrigation pumping station, including a float 3 and a pumping station 2. The pumping station 2 is set on a concrete foundation 1. A water inlet pipe 4 is provided between the float 3 and the pumping station 2. A submersible sewage pump 5 is installed on the float 3. The submersible sewage pump 5 is used to pump water into the water inlet pipe 4, while the pumping station 2 is used to filter the water and provide a fertilizer application point, thereby pumping out irrigation water source with integrated water and fertilizer from the pumping station. Based on this, the float 3 provided by this utility model includes an annular body 31, the top and bottom surfaces of the annular body 31 are both conical surfaces, a debris-blocking cylinder 32 is provided at the bottom of the annular body 31, the submersible pump 5 is located inside the debris-blocking cylinder 32, a clamp 33 for installing the submersible pump 5 is provided inside the annular body 31, two symmetrically distributed hinge ears 34 are provided on the side of the annular body 31, a first hinge rod 6 is provided on the hinge ear 34, a first hinge chain 7 connected to the first hinge rod 6 is provided near the two side edges of the concrete foundation 1, a pipeline support mechanism 8 is provided on both the float 3 and the concrete foundation 1, the water inlet pipe 4 is connected to the pipeline support mechanism 8, a steel wire corrugated pipe 9 is provided on the top of the submersible pump 5 and the water inlet side of the pump station 2, and the end of the steel wire corrugated pipe 9 is connected to the water inlet pipe 4.

[0029] Specifically, the annular design of the float 3 has a continuous and uniform force-bearing surface, which can obtain a relatively uniform force on the water surface. Its conical surface design and the weight of the submersible pump 5 can make the entire float 3 have a relatively stable draft, so that the equipment can maintain a sufficient pumping working surface as the water depth changes. The debris-blocking cylinder 32 can play a role in maintaining the center of gravity in the center, and can also filter debris, especially some algae and floating garbage on the water surface. Furthermore, the float 3 is connected to the pump station 2 via a hinge lug 34, a first hinge 7, and a first hinge rod 6. An additional hinge, preferably a universal hinge, can be added between the hinge lug 34 and the first hinge rod to ensure the float can move up and down. The triangular system formed by the two first hinge rods can limit the lateral swing of the float. Therefore, the float 3 is not only subject to buoyancy from the water surface, but its maximum swing can also be controlled by the first hinge 7 and the second hinge 11, preventing it from colliding with the concrete foundation 1. Furthermore, the flexible traction effect of the corrugated steel pipe 9 and the inlet pipe 4 effectively improves the floating balance of the float 3 on the water inlet side of the pump station 2. The pipeline support mechanism 8 supports the inlet pipe 4 and also adopts an anti-corrosion spray design. The two ends of the inlet pipe 4 utilize the corrugated steel pipe 9 to establish a flexible connection between the pump station 2, the inlet pipe 4, and the float 3, which helps improve the reliability of the pumping equipment and the actual service life of the pipeline.

[0030] To improve the dynamic balance of the pontoon 3, the hinge lug 34 provided by this utility model is provided with a second hinge rod 10. Two second hinges 11 are provided near the center of the concrete foundation 1, and the second hinges 11 are connected to the second hinge rods 10 in a one-to-one correspondence. Furthermore, both the first hinge 7 and the second hinge 11 are universal hinges. An additional hinge, preferably a universal hinge, can be added between the hinge lug 34 and the second hinge rod 10 to ensure the smooth up-and-down movement of the pontoon. The connection system formed by the multiple hinge nodes of the first hinge rod 6 and the second hinge rod 10 on the pontoon and the concrete foundation further ensures the balance of the pontoon.

[0031] To prevent the inlet pipe 4 from being pulled and swayed arbitrarily, the pipe support mechanism 8 provided by this utility model includes a bracket 81. A lower clamp 82 is provided on the top of the bracket 81, and an upper clamp 83 is provided above the lower clamp 82. The upper clamp 83 and the lower clamp 82 are connected by bolts 84. Both ends of the inlet pipe 4 can pass through the circular opening formed by the upper clamp 83 and the lower clamp 82, and then connect to the steel wire corrugated pipe 9. This achieves a flexible connection between the float 3 and the pump station 2, while ensuring the reliability of the pipe connection node, which is beneficial to ensuring the pumping performance of this equipment.

[0032] To improve the support strength of the bracket 81, the bracket 81 provided by the present invention is E-shaped, with the opening of the bracket 81 facing upward and its three vertices welded to the lower hoop 82. The line connecting the welding nodes of the bracket 81 and the lower hoop 82 is a triangle. In particular, the middle part of the bracket 81 can be supported at the lowest point of the lower hoop 82, forming a reliable connection with the other two welding positions, and providing more stable support and positioning conditions for the water inlet pipe 4.

[0033] Furthermore, the pontoon 3 provided by this utility model has an axial opening 35 at its top, a flange plate 36 at its top, and a flange cover 37 connected to the flange plate 36 by fixing bolts. The center of the flange cover 37 is through which the wire corrugated pipe 9 passes and is connected to the flange of the wire corrugated pipe 9. The flange connection surfaces of the flange plate 36, the flange cover 37, and the wire corrugated pipe 9 are concentric but not parallel. The connection of these three components can prevent backflow in the middle of the pontoon 3, and the establishment of flexible connection points helps to improve the overall dynamic balance of the pontoon 3.

[0034] To improve the performance of the internal equipment of pump station 2, the pump station 2 provided by this utility model includes an integrated pump house 21. The integrated pump house 21 has an inlet centrifugal pipe 22, a centrifugal pump 23 installed along the inlet path of the inlet centrifugal pipe 22, a sand filter 24 installed on the outlet side of the inlet centrifugal pipe 22, a drain pipe installed at the bottom of the sand filter 24, a mesh filter 25 installed on the clean water outlet side of the sand filter 24, and an outlet pipe 26 installed on the outlet pipe 26. A flow meter 27, a pressure gauge 28, and a fertilizer application pipe 29 are installed on the outlet pipe 29, and a fertilizer applicator 210 is installed at the supply end of the fertilizer application pipe 29. The integrated pump house 21 also has an integrated power cabinet 211 and a camera 212 installed inside. The integrated power cabinet 211 is used to control the various pumps, valves, and pressure detection structures inside pump station 2, while the camera 212 is used to monitor the actual operation of the internal equipment of pump station 2. The sand and gravel filter 24 includes at least two filter tanks connected in series. In this way, the water pumped into the integrated pump house 21 can be fully filtered through the sand and gravel filter 24 and the mesh filter 25. The water entering the outlet pipe 26 can be fertilized by the fertilizer applicator 210 to achieve integrated water and fertilizer, which facilitates the implementation of integrated water and fertilizer irrigation function.

[0035] Furthermore, the integrated pump room 21 features a concealed drainage ditch at the bottom of the equipment room to ensure proper drainage. A wear-resistant rubber floor mat is laid on top of the anti-slip plate in the equipment room to meet waterproofing and anti-static requirements. An odor-proof, high-efficiency drainage system is installed at the drainage ditch outlet to meet odor, insect, and rodent control requirements.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
