Description

Technical Field

[0001] The invention relates to the field of hydropower technology, and in particular to a static water body non-powered hydropower generation device. Background Technology

[0002] Hydropower, as a clean and renewable energy technology, has long relied primarily on the kinetic energy of water flow or the gravitational potential energy generated by the difference in water level. Traditional hydropower systems, such as river hydroelectric power stations, pumped storage power stations, and micro run-of-river hydroelectric units, all require the water body to have continuous flow characteristics or artificially constructed water level differences (such as dams). The core of these devices lies in using the movement or potential energy changes of water to drive the turbine to rotate, thereby driving the generator to work.

[0003] However, in many natural or artificial water bodies, the water is relatively still, such as inland lakes, enclosed ponds, the center of reservoirs, deep wells, or industrial water storage containers. While these static water bodies contain enormous hydrostatic pressure (approximately one atmosphere increases in pressure for every 10 meters of depth), traditional hydroelectric power generation technologies cannot directly utilize it because hydrostatic pressure itself does not generate continuous flow. To extract high-pressure water, external power (such as water pumps) is typically required to overcome the pressure and establish circulation, resulting in a negative net energy output.

[0004] Therefore, there is an urgent need for a device that can generate electricity by drawing flowing water from static water bodies without consuming external power, in order to fill the technological gap in static water body power generation. Summary of the Invention

[0005] The invention aims to solve the technical problems existing in the prior art. To this end, the invention provides a static water body non-powered hydroelectric power generation device that generates electricity by drawing flowing water from a static water body without consuming external power, relying on air pressure energy, thus filling the technical gap in static water body power generation.

[0006] The technical solution adopted by the invention to solve its technical problem is:

[0007] A static water body non-powered hydroelectric power generation device is provided, including a pneumatic booster pump submerged in the water body and a miniature hydroelectric generator located above the water surface and connected to the outlet pipe of the pneumatic booster pump.

[0008] The pneumatic booster pump includes a water tank, an inlet pipe located at the top of the water tank, a first anti-backflow valve located inside the inlet pipe, a first hydraulically controlled vent pipe located inside the water tank for venting air, a booster pipe assembly located at the bottom of the water tank, a bottom chamber connected to the booster pipe assembly, a second hydraulically controlled vent pipe located inside the bottom chamber for venting air, and an outlet pipe, wherein:

[0009] The booster pipe assembly includes a connecting pipe, a return water cover inverted at the top opening of the connecting pipe, and a booster component installed inside the connecting pipe. The top of the connecting pipe extends to the set outlet water level in the water storage tank, and its bottom extends below the design water level of the bottom compartment to form a water seal.

[0010] The pressurization assembly includes a pressurizer and a second anti-backflow valve located below the pressurizer. The pressurizer consists of a central tube and a flange ring located at the top of the central tube and connected to the inner wall of the connecting pipe. The flow cross-sectional area of ​​the second anti-backflow valve is smaller than the water flow area of ​​the central tube, so that a water-sealed air chamber can be formed between the second anti-backflow valve and the outer wall of the central tube.

[0011] The first hydraulic vent pipe and the second hydraulic vent pipe are respectively configured such that: when the liquid level in the water storage tank reaches the set outlet water level, the first hydraulic vent pipe is closed; when the liquid level in the bottom tank reaches the design water level, the second hydraulic vent pipe is closed.

[0012] The inlet pipe and the connecting pipe are coaxially arranged, and the inner diameter of the inlet pipe is larger than the outer diameter of the return water cover. The inlet pipe extends to below the liquid surface in the water storage tank to form a water seal.

[0013] In some optional embodiments, the inlet pipe of the air pressure booster pump is submerged at least 15 cm below the water surface, and the inlet of the inlet pipe is equipped with a filter cap.

[0014] In some alternative embodiments, the water inlet pipe consists of a main water inlet pipe and a connecting pipe flange connected to the main water inlet pipe. The connecting pipe is welded to the water storage tank, and the diameter of the main water inlet pipe is larger than the diameter of the connecting pipe.

[0015] In some optional embodiments, the first anti-backflow valve and the second anti-backflow valve have the same structure, including a valve body, a water outlet cap and a float. The bottom of the central hole of the valve body is provided with a conical hole. The water outlet cap is screwed to the bottom of the valve body and has a plurality of water outlet holes arranged in a ring on its bottom surface. The center of the water outlet cap is provided with a central hole. The float is a thin-walled frustum-shaped cone, which is placed inside the water outlet cap and completely covers the central hole. The anti-backflow is achieved by using the float to float up and block the conical hole of the valve body.

[0016] In some alternative embodiments, the connecting pipe is formed by screwing together multiple short pipe sections, and at least one short pipe section is provided with a pressurization component.

[0017] In some optional embodiments, the pressurization assembly includes a bundle of tubes and a pressurizer and a second anti-backflow valve disposed within the bundle of tubes. The bundle of tubes includes multiple small tubes arranged in a circular array within a connecting tube, and perforated plates disposed at the top and bottom of the bundle of tubes to isolate adjacent small tubes. The perforated plates are fixedly disposed within the connecting tube. Each of the small tubes is provided with a pressurizer and a second anti-backflow valve from top to bottom.

[0018] The first and second hydraulically controlled exhaust pipes have the same structure, both including an exhaust pipe body and a float valve installed on the exhaust pipe body. The end of the exhaust pipe body of the first and second hydraulically controlled exhaust pipes with the float valve installed is respectively located in the water storage tank and the bottom compartment, and the pipe opening at this end is above the liquid surface. The other end of the exhaust pipe body of the first and second hydraulically controlled exhaust pipes extends out of the water surface and is equipped with a switch.

[0019] One end of the water outlet pipe is vertically located at the bottom of the tank, and the other end extends out to the water surface and connects to the micro hydroelectric generator. The end of the water outlet pipe located inside the tank is also equipped with a pressure boosting cover, and the water outlet pipe extends into the pressure boosting cover.

[0020] A flow booster is also provided between the water outlet pipe and the micro hydroelectric generator. The flow booster includes a tank and a third hydraulically controlled vent pipe or manual vent switch located on the tank. The water outlet pipe extends below the liquid level inside the tank. The bottom of the tank is connected to the micro hydroelectric generator through a connecting pipe.

[0021] The micro hydroelectric generator includes two units arranged vertically. The water flow from the outlet pipe drives the upper micro hydroelectric generator, and the water discharged from the upper micro hydroelectric generator drives the lower micro hydroelectric generator. The two micro hydroelectric generators are electrically connected to a battery or a user.

[0022] Compared with existing technologies, the beneficial effects of the invention are:

[0023] The pneumatic booster pump designed in this invention can push static water out of the water surface to drive a micro hydroelectric generator to generate electricity, filling the technological gap in static water power generation. Moreover, the pneumatic booster pump does not require external power during operation, is energy-saving and environmentally friendly, and has the advantages of simple structure and low cost.

[0040] Example 1

[0041] As attached Figure 1 As shown, this embodiment provides a static water body non-powered hydroelectric power generation device, including a pneumatic booster pump submerged in the water body and a miniature hydroelectric generator 9 located above the water surface and connected to the outlet pipe 8 of the pneumatic booster pump. In this embodiment, the pneumatic booster pump is submerged at least 15cm below the water surface, meaning the inlet of the pneumatic booster pump is at least 15cm below the water surface. This ensures sufficient water intake and a certain water pressure during operation. Theoretically, the deeper the submersion, the better, because the deeper the water intake, the greater the water pressure. Preferably, to prevent foreign objects from clogging the pneumatic booster pump through the inlet pipe, this embodiment provides a filter cap at the inlet of the inlet pipe.

[0042] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 6 and attached Figure 7As shown, the pneumatic booster pump includes a water tank 2, an inlet pipe 1 located at the top of the water tank, a first anti-backflow valve 3 located inside the inlet pipe, a first hydraulically controlled vent pipe 4 located inside the water tank for venting air, a booster pipe assembly 5 located at the bottom of the water tank, a bottom chamber 6 connected to the booster pipe assembly, a second hydraulically controlled vent pipe 7 located inside the bottom chamber for venting air, and an outlet pipe 8, wherein:

[0043] The water storage tank 2 has a cylindrical structure, with its top and bottom fixedly connected to the water inlet pipe 1 and the booster pipe group 5, respectively, forming a sealed cavity inside.

[0044] The booster pipe assembly 5 includes a connecting pipe 5.1, a return water cover 5.2 inverted at the top opening of the connecting pipe, and a booster component disposed inside the connecting pipe. The top of the connecting pipe 5.1 extends to the set outlet water level 2A in the water storage tank 2, and its bottom extends below the design water level 6A of the bottom compartment 6 to form a water seal. In this embodiment, the inner diameter of the return water cover 5.2 is larger than the outer diameter of the connecting pipe 5.1, and it is fixedly connected to the connecting pipe by multiple connecting ribs.

[0045] The pressurization assembly in this embodiment includes a pressurizer 5.3 and a second anti-backflow valve 5.4 located below the pressurizer. The pressurizer 5.3 consists of a central pipe 5.3.1 and a flange ring 5.3.2 located at the top of the central pipe and connected to the inner wall of the connecting pipe. The flow cross-sectional area of ​​the second anti-backflow valve 5.4 is smaller than the water flow area of ​​the central pipe 5.3.1, so that a water-sealed air chamber can be formed between the second anti-backflow valve 5.4 and the outer wall of the central pipe 5.3.1.

[0046] The inlet pipe 1 is coaxially arranged with the connecting pipe 5.1, and its inner diameter is larger than the outer diameter of the return water cover 5.2. The inlet pipe 1 extends to below the liquid surface in the water storage tank 2 to form a water seal.

[0047] In this embodiment, the inlet water volume of the water storage tank 2 should be greater than the outlet water volume of the connecting pipe; the diameter of the outlet pipe 8 is much smaller than the diameter of the connecting pipe 5.1, that is, the outlet water volume is much smaller than the inlet water volume of the bottom tank.

[0048] The first hydraulically controlled vent pipe 4 and the second hydraulically controlled vent pipe 7 have the same structure, both including a vent pipe body A-1 and a float valve A-2 installed on the vent pipe body. The ends of the vent pipe bodies of the first and second hydraulically controlled vent pipes with the float valves are respectively located inside the water storage tank and the bottom compartment, with the pipe openings at these ends above the liquid surface. The other ends of the vent pipe bodies of both the first and second hydraulically controlled vent pipes extend beyond the water surface. In this embodiment, the first and second hydraulically controlled vent pipes are configured such that: when the liquid level in the water storage tank reaches the set outlet water level, the first hydraulically controlled vent pipe closes; when the liquid level in the bottom compartment reaches the designed water level, the second hydraulically controlled vent pipe closes.

[0049] Preferred options are listed below. Figure 1 and attached Figure 5 As shown, the first anti-backflow valve 3 and the second anti-backflow valve 5.4 in this embodiment have the same structure, including a valve body B-1, a water outlet cap B-2 and a float B-3. The bottom of the central hole of the valve body B-1 is provided with a conical hole B-1-1. The water outlet cap B-2 is screwed to the bottom of the valve body B-1, and its bottom surface has a plurality of water outlet holes B-2-1 arranged in a ring. The center of the water outlet cap B-2 is provided with a central hole B-2-2. The float B-3 is a thin-walled frustoconical type. It is placed in the water outlet cap B-2 and completely covers the central hole B-2-2. The anti-backflow is achieved by using the float to float and block the conical hole of the valve body.

[0050] One end of the water outlet pipe 8 is vertically located at the bottom of the bottom chamber 6, and the other end extends out to the water outlet surface and connects to the micro hydroelectric generator 9. The end of the water outlet pipe 8 located inside the bottom chamber 6 is also equipped with a pressure boosting cover 10, and the water outlet pipe 8 extends into the pressure boosting cover 10.

[0051] The working principle of the pneumatic booster pump described in this embodiment is as follows:

[0052] The air pressure booster pump is vertically placed into the water body, preferably submerged in deep water. Water flows into the storage tank through the inlet pipe. During the water storage process, the storage tank vents air to the outside through the first hydraulic control vent pipe. When the water level in the storage tank reaches the outlet water level, the first hydraulic control vent pipe automatically closes. At this time, the water continues to flow into the storage tank. Since the inflow is greater than the outflow, the water level in the storage tank will continue to rise. The bottom of the inlet pipe is below the water surface, forming a water seal. Some air is compressed in the storage tank to form an air chamber, increasing the outlet water pressure of the storage tank.

[0053] Water flows from the connecting pipe into the bottom tank through the booster pipe assembly, and the bottom tank begins to fill with water. During the water filling process, air is vented to the outside through the second hydraulic control vent pipe. When the water level in the bottom tank reaches the design water level, the second hydraulic control vent pipe automatically closes. At this time, the connecting pipe is below the liquid surface, forming a water seal. Since the water output of the outlet pipe is less than the water inflow of the bottom tank, after the second hydraulic control vent pipe is closed, some air will be compressed in the bottom tank, forming an air chamber above the liquid level, which increases the water output pressure of the outlet pipe.

[0054] The connecting pipe of the booster pipe assembly is designed with a booster and a second anti-backflow valve. Since the flow cross-sectional area of ​​the second anti-backflow valve is smaller than the water flow area of ​​the central pipe, a water seal air chamber can be formed between the second anti-backflow valve and the central pipe, increasing the outlet water pressure of the connecting pipe.

[0055] The first anti-backflow valve and the second anti-backflow valve can prevent water from flowing back and ensure that water can only flow out from the outlet pipe.

[0056] The pressure booster shroud installed on the water outlet pipe can also form an air chamber inside, further increasing the water outlet pressure.

[0057] This embodiment achieves water pressure above the water surface by setting multiple air chambers in the air pressure booster pump, and uses the outflowing water to drive a micro hydroelectric generator to do work, thus realizing hydroelectric power generation.

[0058] Preferred options are listed below. Figure 1 and attached Figure 4 As shown, the water inlet pipe 1 in this embodiment consists of a main water inlet pipe 1.1 and a connecting pipe 1.2 connected to the flange of the main water inlet pipe. The connecting pipe 1.2 is welded to the water storage tank 2, and the diameter of the main water inlet pipe 1.1 is larger than the diameter of the connecting pipe 1.2. The first anti-backflow valve 3 is screwed to the port of the connecting pipe 1.2.

[0059] Preferred options are listed below. Figure 1 As shown, the connecting pipe 5.1 in this embodiment is formed by screwing together multiple short pipe sections, and at least one short pipe section is provided with a pressurization component.

[0060] Preferred options are listed below. Figure 1 As shown, in this embodiment, both the first hydraulic exhaust pipe 4 and the second hydraulic exhaust pipe 7 are equipped with switches 11 at their openings above the liquid surface. When the device is operating normally, the switches are turned off to prevent foreign objects from entering the first hydraulic exhaust pipe and the second hydraulic exhaust pipe and causing blockage.

[0061] Example 2

[0062] The difference from Embodiment 1 lies in the different booster components, as shown in the attached diagram. Figure 8 As shown, the pressurization assembly in this embodiment includes a bundled tube group 5.5 and a pressurizer 5.3 and a second anti-backflow valve 5.4 disposed within the bundled tube group. The bundled tube group 5.5 includes multiple small tubes 5.5.1 arranged in a circular array within a connecting tube, and perforated plates 5.5.2 disposed at the top and bottom of the bundled tube group to isolate adjacent small tubes. The perforated plates 5.5.2 are fixedly disposed within the connecting tube 5.1. Each small tube 5.5.1 is provided with a pressurizer 5.3 and a second anti-backflow valve 5.4 from top to bottom.

[0063] The structure of the booster and the second anti-backflow valve in this embodiment is the same as that in Embodiment 1.

[0064] The booster assembly designed in this embodiment can reduce the size of each component, and its function is the same as that in Embodiment 1.

[0065] Example 3

[0066] Based on Example 1 or Example 2, as shown in the appendix Figure 2As shown, this embodiment also includes a flow booster 12 between the water outlet pipe 8 and the micro hydroelectric generator 9. The flow booster 12 includes a tank 12.1 and a third hydraulically controlled vent pipe or manual vent switch 12.2 located on the tank. The water outlet pipe 8 extends below the liquid level inside the tank 12.1, and the bottom of the tank 12.1 is connected to the micro hydroelectric generator 9 via a connecting pipe 13. This design also utilizes the formation of an air chamber inside the tank to increase the water outlet pressure and improve the kinetic energy of the water flow, thereby increasing the power generation efficiency.

[0067] Example 4

[0068] Based on any of the above-described embodiments, as shown in the appendix Figure 2 As shown, this embodiment has two micro hydroelectric generators 9, which are arranged one above the other. The water flow from the outlet pipe drives the upper micro hydroelectric generator, and the water discharged from the upper micro hydroelectric generator drives the lower micro hydroelectric generator, thus forming a high-efficiency micro hydroelectric cascade power generation system. The two micro hydroelectric generators are electrically connected to a battery or the user.

[0069] In one embodiment, the total length of the air pressure booster pump can be designed to be about 12 meters, with the inlet pipe being a φ2m pipe and the outlet pipe being a φ10cm pipe.

[0070] The above description is merely an embodiment of the invention and does not limit the patent scope of the invention. Any equivalent structural or procedural changes made using the content of the invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the invention.
