Description

Technical Field

[0001] This utility model relates to the field of power generation equipment technology, specifically a pipeline power generation device based on water potential energy. Background Technology

[0002] Water turbine pumps, as devices that utilize the energy of water flow to lift water, are widely used in agricultural irrigation, industrial water supply, and other fields. However, traditional water turbine pump structures have some design shortcomings that affect their overall performance and service life.

[0003] Specifically, traditional water turbine pumps often use simple connection methods at the inlet and water pipe connection, such as flange or clamp connections. While these methods can achieve the connection between the inlet and water pipes to a certain extent, problems such as loosening and poor sealing can easily occur during long-term use. These problems not only lead to water leakage and reduce the pump's efficiency, but may also damage the equipment and increase maintenance costs.

[0004] To address these issues, those skilled in the art have proposed a pipeline power generation device based on water potential energy. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a pipeline power generation device based on water potential energy, aiming to improve the working efficiency, stability, and service life of the water turbine pump by optimizing component design and connection methods. One of the main improvements is the installation of a threaded sealing gasket at the connection between the inlet and the water pipe, which ensures a tighter connection between the inlet and the water pipe, effectively solving problems such as poor sealing and loose connections inherent in traditional connection methods.

[0006] A pipeline power generation device based on water potential energy includes a power generation device body, a drain pipe at the bottom end of the power generation device body, a water inlet pipe installed on the side wall of the power generation device body, and a limit collar installed at the outermost end of the water inlet pipe.

[0007] An impeller body is installed in the middle of the main body of the power generation equipment. An impeller nut is installed at the top of the impeller body where it is connected to the main body of the power generation equipment. Three limit nuts are threaded around the impeller body. A drain cone bolt is also installed at the outlet end of the drain pipe.

[0008] A sealing mechanism is provided on the outside of a limiting collar, a guide tube is provided on the outside of the limiting collar, and a sealing plug is provided between the limiting collar and the guide tube.

[0009] A tightening mechanism is provided between the limiting collar and the guide tube.

[0010] Preferably, the three limiting nuts limit the impeller body within the generator body via the generator body.

[0011] Preferably, a small pressure ring is provided on the top of the main body of the power generation equipment, a pump cover is installed on the top of the main body of the power generation equipment near the impeller body, and a water guide seat is provided on one side of the bottom end of the main body of the power generation equipment.

[0012] Preferably, the tightening mechanism includes a sidewall sealing gasket, which is fixedly connected to both sides of the sealing plug in two forms, and two limiting sleeves are installed at both ends of the limiting collar corresponding to the positions of the sidewall sealing gasket.

[0013] Preferably, the sidewall sealing gasket has a connecting groove in the middle, one end of the limiting sleeve is a groove for placing the sidewall sealing gasket, and the other side has two connections corresponding to the position of the sidewall sealing gasket.

[0014] Preferably, two compression gaskets are sleeved on the outer side of the guide tube. Two protrusions are fixedly connected to both sides of the two compression gaskets. A connecting groove is also opened in the middle of the two protrusions. A limiting screw is installed in the connecting groove opened in the compression gasket. The limiting screw also passes through the connecting groove in the side wall sealing gasket and the limiting sleeve. The other end of the limiting screw is threaded to a limiting screw sleeve. The limiting screw sleeve is set on the outer side wall of the limiting sleeve near the connecting groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model features a threaded sealing gasket at the connection between the water inlet and the water pipe, a design that significantly enhances the sealing performance of the connection. The sealing gasket effectively fills the connection gaps, preventing water leakage and thus improving the overall operating efficiency of the water turbine pump. Compared to traditional connection methods, the sealing design of this utility model is more reliable and can maintain a stable sealing effect over a long period.

[0017] 2. By adopting an impeller with high-efficiency blade design and a streamlined pump casing and tailpipe design, the flow efficiency and impeller rotation efficiency are significantly improved, thereby enhancing the overall working efficiency of the water turbine pump. This structural optimization not only enables the water turbine pump to provide a greater head and water output under the same hydraulic conditions, but also reduces energy loss and improves energy utilization efficiency.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] As attached Figure 1 To be continued Figure 3 As shown:

[0024] Example 1: According to Figure 1 and Figure 2 As shown, this utility model provides a pipeline power generation device based on water potential energy, including a power generation device body 1, a drain pipe 2 provided at the bottom end of the power generation device body 1, a water inlet pipe 3 installed on the side wall of the power generation device body 1, and a limit collar 4 installed at the outermost end of the water inlet pipe 3.

[0025] An impeller body 7 is installed in the middle of the main body 1 of the power generation equipment. An impeller nut 5 is installed at the top of the impeller body 7 where it is connected to the main body 1 of the power generation equipment. Three limit nuts 6 are threaded around the impeller body 7. A drain cone bolt 8 is also installed at the outlet end of the drain pipe 2.

[0026] A sealing mechanism is provided on the outside of the limiting collar 4. A guide tube 12 is provided on the outside of the limiting collar 4. A sealing plug 13 is provided between the limiting collar 4 and the guide tube 12.

[0027] A tightening mechanism is provided between the limiting collar 4 and the guide pipe 12. Three limiting nuts 6 limit the impeller body 7 within the generator body 1. A small pressure ring 9 is provided on the top of the generator body 1. A pump cover 10 is installed on the top of the generator body 1 near the impeller body 7. A water guide seat 11 is provided on one side of the bottom end of the generator body 1. By adopting an impeller with high-efficiency blade design and a streamlined pump casing and tailpipe design, the water flow efficiency and impeller rotation efficiency are significantly improved, thereby improving the overall working efficiency of the water turbine pump. This structural optimization not only enables the water turbine pump to provide a larger head and water output under the same hydraulic conditions, but also reduces energy loss and improves energy utilization efficiency.

[0028] Example 2: According to Figure 1 and Figure 3 As shown, the tightening mechanism includes a sidewall sealing gasket 14, which is fixedly connected to both sides of the sealing plug 13. Two limiting sleeves 15 are installed at the ends of the limiting collar 4 corresponding to the positions of the sidewall sealing gaskets 14. A connecting groove is formed in the middle of the sidewall sealing gasket 14. One end of each limiting sleeve 15 is a groove for placing the sidewall sealing gasket 14, and two connections are formed on the other side corresponding to the positions of the sidewall sealing gasket 14. Two compression gaskets 16 are sleeved on the outer side of the guide tube 12. Two protrusions are fixedly connected to both sides, and a connecting groove is also formed in the middle of the two protrusions. A limiting screw 17 is installed in the connecting groove formed in the compression gasket 16. The limiting screw 17 also passes through the connecting groove in the side wall sealing gasket 14 and the limiting sleeve 15. The other end of the limiting screw 17 is threadedly connected to a limiting sleeve 18. The limiting sleeve 18 is set on the outer side wall of the limiting sleeve 15 near the connecting groove. A threaded sealing gasket is provided at the connection between the water inlet and the water pipe. This design significantly enhances the sealing performance of the connection. The sealing gasket can effectively fill the connection gap and prevent water leakage at the connection, thereby improving the overall working efficiency of the water turbine pump.

[0029] Working principle: When water flows into the main body 1 of the power generation equipment through the inlet pipe 3, the water flow is accelerated and generates kinetic energy under the action of the impeller body 7. The rotation of the impeller body 7 drives the main shaft to rotate, thereby driving the generator to generate electricity. During installation, firstly, the sealing plug 13 is inserted into the limiting sleeve 4, and the side wall sealing gasket 14 is aligned with the limiting sleeve 15 and inserted. Then, the compression gasket 16 is slid to the position of the sealing plug 13. Next, the limiting screw 17 passes through the compression gasket 16, the limiting screw 17, and the limiting sleeve 15 and comes out from the rear end of the limiting sleeve 4. Then, the limiting screw sleeve 18 applies force to the limiting screw 17, causing the limiting screw 17 to pull the compression gasket 16, causing the compression gasket 16 to squeeze the sealing plug 13 forward, squeezing the sealing plug 13 and filling it into the limiting sleeve 4, thus sealing the guide pipe 12 and the limiting sleeve 4.
