Description
Technical Field
[0001] This utility model relates to the field of power generation system technology, specifically a water gravity source negative pressure self-circulating water device. Background Technology
[0002] Hydropower, as a clean and renewable energy source, is widely used in various scenarios. Traditional waterwheel power generation systems typically utilize the kinetic energy of natural water flows such as rivers and streams to impact a waterwheel, which in turn drives a generator to produce electricity. While these systems are relatively simple in structure, they have significant limitations in practical applications. First, their power generation efficiency and stability heavily depend on the flow rate and volume of the natural water. In dry seasons or areas with slow water flow, insufficient water momentum causes the waterwheel to rotate slowly or even stop, resulting in a sharp drop in power generation or even complete failure to generate electricity, severely limiting their applicability. Second, traditional waterwheels typically use a single-use water model, discharging water directly after it impacts the waterwheel without effective recycling. This not only wastes water resources but also makes it difficult to promote the application of such power generation systems in water-scarce areas. In addition, some improvement schemes attempt to accelerate water flow by constructing canals or setting confluence plates, or to use buoyancy devices to adjust the position of waterwheels to adapt to water level changes (e.g., CN104595092A, CN104653388A). However, these improvements still do not fundamentally solve the problem of dependence on continuous and stable external water flow, nor do they achieve closed-loop recycling of water resources. Summary of the Invention
[0003] In view of the shortcomings of existing waterwheel power generation systems, this utility model provides a water gravity source negative pressure self-circulating water device, which can overcome the limitations of natural water flow, realize the internal circulation of water resources, and generate electricity stably and efficiently.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a water gravity source negative pressure self-circulating water device, comprising at least one water circulation unit, wherein the water circulation unit includes a water tank and a vacuum pump installed on the top of the water tank; the water tank is connected to a water collection tank via a pumping pipe, the pumping pipe including a first inlet extending into the water collection tank and a first outlet extending into the water tank; the water tank is connected to a water-carrying basket via an outlet pipe, the outlet pipe including a second inlet communicating with the water tank and a second outlet facing the water wheel; the horizontal height of the first outlet is higher than the horizontal height of the second inlet; the vacuum pump is used to create negative pressure in the water tank to draw water from the water collection tank through the pumping pipe, and the water is supplied to the water wheel through the outlet pipe to drive the water wheel to rotate.
[0005] Furthermore, there are multiple water circulation units, and the second water outlets of multiple water outlet pipes are centrally arranged on the upper half-circle of the water wheel drive side.
[0006] Furthermore, the number of water circulation units is five, arranged side by side on the top of the support frame.
[0007] Furthermore, each water circulation unit is connected to two pumping pipes and two outlet pipes.
[0008] Furthermore, a one-way valve is provided at the first water inlet end.
[0009] Furthermore, a solenoid valve is provided in the middle of the water outlet pipe.
[0010] Furthermore, the water collection tank is equipped with a filter.
[0011] Furthermore, the vacuum pump and the solenoid valve are electrically connected to the controller.
[0012] This utility model provides a water gravity source negative pressure self-circulating water device, which has the following beneficial effects: 1. The negative pressure water circulation system is constructed by setting up a water circulation unit including a water tank and a vacuum pump, and connecting the water collection tank and the water wheel with a water pumping pipe and a water outlet pipe. It is a water circulation system based on the principle of negative pressure. The vacuum pump creates negative pressure in the water tank, which can efficiently and automatically pump the water in the water collection tank to a higher position, and then supply the water wheel through the water outlet pipe to drive its rotation. This design gets rid of the strong dependence of traditional waterwheels on the natural water flow speed and drop, realizes the internal recycling of water resources, and significantly saves water resources.

Detailed Implementation The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Please see the appendix Figure 1 As shown, this utility model provides an energy-saving water source circulation gravity power generation system 100, including a support frame 1, a water wheel 2, and a water gravity source negative pressure self-circulating water device. The water wheel 2, as the core rotating component, converts the gravitational potential energy of water into mechanical energy for power generation. The water wheel 2 is installed inside the support frame 1 via a main shaft 11 and can rotate under the drive of water flow. The outer ring of the water wheel 2 is provided with a water groove 21, and multiple equidistantly spaced water-carrying baskets 22 are assembled within the water groove 21. The support frame 1 is preferably trapezoidal, providing overall structural support and ensuring the stability of the device. The bottom of the support frame 1 is provided with a water collection tank 12 to receive water flowing from the water-carrying baskets 22, facilitating recycling. The water groove 21 accommodates the water-carrying baskets 22 and water, ensuring that the water-carrying baskets 22 and water move along a fixed path. The water-carrying baskets 22 use gravity to drive the water wheel 2 to rotate.
[0021] Please see the appendix Figure 1-6 As shown, the water gravity source negative pressure self-circulating water device of this utility model serves as a key energy-saving component, realizing water circulation from bottom to top. The negative pressure water circulation system includes at least one water circulation unit 3 installed on the top of the support frame 1. The water circulation unit 3 includes a water tank 33 and a vacuum pump 34 installed on top of the water tank 33. The water tank 33 is connected to the water collection tank 12 via a water extraction pipe 31, as shown in the attached diagram. Figure 2-4 As shown, the water pumping pipe 31 includes a first inlet end 311 extending into the water collection tank 12 and a first outlet end 312 extending into the water tank 33. The water tank 33 is connected to the water-carrying basket 22 via an outlet pipe 32, as shown in the attached diagram. Figure 2-4 As shown, the water outlet pipe 32 includes a second water inlet 321 connected to the water tank 33 and a second water outlet 322 facing the water wheel 2. The vacuum pump 34 is used to create negative pressure in the water tank 33 to draw water from the water collection tank 12 through the water pumping pipe 31. The water is supplied to the water wheel 2 through the water outlet pipe 32 to drive the water wheel 2 to rotate. The horizontal height of the first water outlet 312 is higher than that of the second water inlet 321, which cleverly utilizes gravity to assist the water flow, reduces the system's operating energy consumption, and improves the energy conversion efficiency and the operational stability and reliability of the entire negative pressure water circulation system.
[0022] This utility model's water gravity source negative pressure self-circulating water device, by setting up a water circulation unit 3 including a water tank 33 and a vacuum pump 34, and using a water pumping pipe 31 and a water outlet pipe 32 to connect the water collection tank 12 and the water wheel 2, constructs a water circulation system based on the principle of negative pressure. By using the vacuum pump 34 to create negative pressure in the water tank 33, the water in the water collection tank 12 can be pumped to a higher position efficiently and automatically, and then supplied to the water wheel 2 through the water outlet pipe 32 to drive its rotation. This design gets rid of the dependence of traditional waterwheels on natural water flow, realizes the internal recycling of water resources, and significantly saves water resources.
[0023] In this utility model, there are multiple water circulation units 3. Through multiple water circulation units 3 and centralized water supply, sufficient water flow is ensured on the driving side of the water wheel 2, thereby improving driving force and power generation efficiency. The second water outlets 322 of multiple water outlet pipes 32 are centrally arranged on the upper half-circle of the driving side of the water wheel 2, and water is supplied to the water-carrying basket 22 passing through this area, thereby maximizing the conversion of gravitational potential energy.
[0024] In this invention, there are five water circulation units 3 arranged side by side on the top of the support frame 1. The parallel arrangement of multiple water circulation units 3 enhances the overall system capacity and power generation capability, making it suitable for large-scale applications.
[0025] In this invention, each water circulation unit 3 is connected to two pumping pipes 31 and two outlet pipes 32. This multi-pipe connection increases the water circulation flow rate, improving system efficiency and stability. The two pumping pipes 31 and two outlet pipes 32 operate in parallel, enhancing pumping and supply speeds.
[0026] In this utility model, as shown in the appendix Figure 4 As shown, a one-way valve 313 is provided at the first water inlet 311. This prevents water from flowing back from the pump pipe 31 and maintains the system pressure.
[0027] In this utility model, as shown in the appendix Figure 2As shown, a solenoid valve 323 is installed in the middle of the water outlet pipe 32. This valve controls the opening and closing of the water outlet pipe 32, enabling on-demand water supply. Valve control improves the reliability and automation level of the power generation system 100, prevents backflow, and precisely controls the water output.
[0028] In this utility model, as shown in the appendix Figure 4 As shown, the water collection tank 12 is equipped with a filter 4, which purifies the circulating water, removes impurities from the water, prevents impurities from clogging the system, protects pipes and pumps, and extends the service life of the equipment.
[0029] In this invention, the vacuum pump 34 and the solenoid valve 323 are electrically connected to a controller (not shown) to achieve automatic start and stop.
[0030] In this utility model, as shown in the appendix Figure 1-2 As shown, the waterwheel 2 includes multiple blades 13 connected to the main shaft 11.
[0031] In this utility model, as shown in the appendix Figure 5-6 As shown, to improve water loading efficiency and prevent leakage, and to reduce water waste, the water-carrying basket 22 has a water inlet 226 at one end, and includes a first side 221, a second side 222, a third side 223, a fourth side 224, and a bottom surface 225. The first side 221 is embedded in the bottom surface 225 of the water ditch 21 to fix the position of the water-carrying basket 22. The second side 222 and the fourth side 224 are respectively fitted and connected to both sides of the water ditch 21 to prevent water from leaking from the sides. A first baffle plate 227 extends from the connection between side 222 and the third side 223, and a second baffle plate 228 extends from the connection between the fourth side 224 and the third side 223. The third side 223 serves as the main bearing surface and works with the baffle plate to prevent water from splashing out. When the water outlet pipe 32 is not aligned with the water inlet 226, water will rush onto the third side 223. At this time, the first baffle plate 227 and the second baffle plate 228 can prevent water from overflowing from the side, guide the water to flow downward, and improve water utilization.
[0032] In this utility model, the direction from the first side 221 to the third side 223 is defined as the width of the water-carrying basket 22, the direction from the inlet 226 to the bottom surface 225 is defined as the depth of the water-carrying basket 22, and the direction from the surface of the water trough 21 to the bottom of the water trough 21 is defined as the depth of the water trough 21. The width of the second side 222 and the fourth side 224 is greater than the depth of the water trough 21, that is, the overall width of the water-carrying basket 22 is greater than the depth of the water trough 21, which can increase the volume of the water-carrying basket 22 and thus increase the accumulation of gravitational potential energy.
[0033] In this invention, the third side surface 223 extends outward from one end of the water inlet 226 and is provided with an inclined plate 229. By setting the inclined plate 229, water is guided to flow smoothly into the water-carrying basket 22, reducing water inlet resistance and splashing, and improving water inlet efficiency; when the water-carrying basket 22 rotates to the lower semicircle of the drive side, the inclined plate 229 can also act as a guide plate, making it easier for the water to flow out slowly and enter the water collection tank 12.
[0034] The energy-saving water source circulation gravity power generation system 100 of this utility model has the following beneficial technical effects: 1. The structure is simple and compact, easy to install and maintain. It generates electricity by gravity, requiring no fuel or external power grid, thus saving energy and protecting the environment. It also enables the recycling of water resources, significantly saving water resources.
[0035] 2. The negative pressure water circulation system has a high degree of automation and stable and reliable operation; the design of the water-carrying basket 22 reduces water waste and can rotate stably to generate electricity efficiently.
[0036] 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.
