Description

Technical Field

[0001] The present invention belongs to the technical field of hydroelectric power generation, and specifically refers to a tower-type water kinetic energy generator set system. Background Art

[0002] With the increasing energy demand, the development and utilization of renewable energy have become particularly important. Traditional hydroelectric power generation methods usually rely on large-scale water conservancy projects, which have high construction costs, long cycles, and strict requirements for the geographical environment, restricting their application in some areas.

[0003] Currently, although there are also some small-scale hydroelectric power generation devices, most of them have problems such as low energy conversion efficiency and poor stability. For example, some simple waterwheel-type power generation devices are greatly affected by water flow velocity and flow rate, and the power generation power is unstable; there are also some power generation devices using the water hammer effect, whose structural design is not reasonable enough, unable to fully utilize the energy of water resources, and prone to failures during operation.

[0004] In addition, for some remote areas or ecologically sensitive areas, traditional power generation methods are difficult to implement, and these areas often have an urgent need for power supply. Therefore, it is of great practical significance to develop a small-scale hydroelectric power generation system with simple structure, low cost, strong adaptability and environmental friendliness. Summary of the Invention

[0005] The technical problem to be solved by the present invention is the problems of low energy conversion efficiency, poor stability, limited applicable range and large environmental impact existing in existing hydroelectric power generation devices, and it is used to achieve efficient and stable power generation in different geographical environments and application scenarios.

[0006] To solve the above problems, the technical solutions adopted by the present invention are as follows:

[0007] The tower-type water kinetic energy generator set system proposed by the present invention includes:

[0008] A water storage tank: used to store the water pumped from the river and provide the height potential energy of the water. The water storage tank is set at a certain height above the river, and its bottom is connected to the river through a pipeline;

[0009] An intelligent control module is arranged in the water storage tank. The intelligent control module is used to monitor parameters such as water level and flow rate in real time, and automatically adjust the operation state of the system according to the monitoring results to achieve the best power generation efficiency;

[0010] A water hammer pump: lifting the water to the water storage tank through the water hammer effect of the river water. Multiple groups of the water hammer pumps are connected to the water storage tank through an inlet pipeline;

[0011] Generator: The generator generates electricity by using the height potential energy of the water stored in the water storage tank. Multiple groups of the generators are connected to the water storage tank through drainage pipes. When the water flows out of the drainage pipes, it has a certain potential energy, which is used to drive the impellers of the generators to rotate, thereby generating electrical energy and generating electricity by using potential energy;

[0012] The generator adopts a turgo generator. Multiple groups of the generators are connected in parallel. Every four groups of generators and four drainage pipes form a module, and multiple modules can be connected in parallel.

[0013] First flow valve: Installed between the water storage tank and the drainage pipe, it is used to control the water flow rate, thereby adjusting the output power of the generator. The first flow valve automatically adjusts the opening degree according to the instructions of the intelligent control module to ensure the stable operation of the system under different working conditions.

[0014] Preferably, a second flow valve is provided on the side of the water inlet pipe close to the water storage tank. The second flow valve is used to control the water flow rate and flow into the water storage tank according to requirements.

[0015] Preferably, the intelligent control module includes a liquid level sensor for monitoring the water level in the water storage tank, a flow meter for detecting the water flow rate, a pressure sensor for monitoring the water pressure, and a central processor connected thereto for data processing. The central processor is connected to the first flow valve and the second flow valve, and automatically adjusts the opening degrees of the first flow valve and the second flow valve according to the monitoring results. It also includes a wireless communication module connected to the central processor. At the same time, data is transmitted to the remote monitoring center through the wireless communication module (such as GPRS, LoRa, etc.). Managers can view the operation status, parameters and alarm information of the system in real time through terminal devices such as mobile phones and computers.

[0016] Preferably, the system further includes an overflow valve. The overflow valve is provided at the top of the water storage tank. When the water level in the water storage tank exceeds the set upper limit, the overflow valve automatically opens to drain the excess water back to the river to prevent the water storage tank from overflowing.

[0017] Preferably, a flow meter is also provided on the drainage pipe. The flow meter is used to monitor the water flow rate and feedback the monitoring data to the intelligent control module.

[0018] Preferably, a water quality purification device is provided at the front end of the water inlet pipe or at the inlet of the hydraulic ram pump. The water quality purification device includes any one or more of a filter screen, a sedimentation tank, and an activated carbon filter. The filter screen can intercept larger sediment and impurities. The sedimentation tank can let sediment and the like settle down and be cleaned regularly. The activated carbon filter can adsorb organic matters, microorganisms and odors in the water, etc., to improve the water quality.

[0019] Adopting the above solution, the beneficial effects obtained by the present invention are as follows:

[0020] 1. By utilizing the water hammer effect of river water and the height potential energy difference of water, efficient energy conversion is achieved, and the power generation efficiency is improved.

[0033] Embodiment 1

[0034] As Figure 1 shown, a tower-type water kinetic energy generator set system proposed by the present invention includes:

[0035] Water storage tank 1: It is used to store the water pumped from the river and provide the height potential energy of the water. The water storage tank 1 is set at a certain height above the river through a high tower, and its bottom is connected to the river through a pipeline.

[0036] An intelligent control module 2 is arranged in the water storage tank 1. The intelligent control module 2 is used to monitor parameters such as water level and flow rate in real time, and automatically adjust the operating state of the system according to the monitoring results to achieve the best power generation efficiency.

[0037] An overflow valve 11 is provided on the water storage tank 1. The overflow valve 11 is arranged at the top of the water storage tank 1. When the water level in the water storage tank 1 exceeds the set upper limit, the overflow valve 11 automatically opens to drain the excess water back to the river to prevent the water storage tank 1 from overflowing.

[0038] Hydraulic ram pump 3: It lifts water to the water storage tank 1 through the water hammer effect of the river water. Multiple groups of the hydraulic ram pumps 3 are connected to the water storage tank 1 through the inlet pipeline.

[0039] Generator 4: The generator 4 generates electricity by using the height potential energy of the water stored in the water storage tank 1. Multiple groups of the generators 4 are connected to the water storage tank 1 through the drainage pipeline. When the water flows out from the drainage pipeline, it has a certain potential energy, which is used to drive the impeller of the generator 4 to rotate, thereby generating electric energy and generating electricity by using potential energy.

[0040] First flow valve 5: It is installed between the water storage tank 1 and the drainage pipeline and is used to control the water flow rate, thereby adjusting the output power of the generator 4. The first flow valve 5 automatically adjusts the opening degree according to the instructions of the intelligent control module 2 to ensure the stable operation of the system under different working conditions.

[0041] Furthermore, a second flow meter is also provided on the drainage pipeline. The second flow meter is used to monitor the water flow rate and feed back the monitoring data to the intelligent control module 2.

[0042] Second flow valve 6: It is arranged on the side of the water inlet pipe close to the water storage tank 1, and the second flow valve 6 is used to control the water flow speed and flow rate into the water storage tank 1 according to requirements.

[0043] Reference Figure 2 As shown, the intelligent control module 2 includes a liquid level sensor 21 for monitoring the water level in the water storage tank 1, a flow meter 22 for detecting the water flow speed, a pressure sensor for monitoring the water pressure, and a central processor connected thereto for data processing. The central processor is connected to the first flow valve 5 and the second flow valve 6, and automatically adjusts the opening degrees of the first flow valve 5 and the second flow valve 6 according to the monitoring results. At the same time, data is transmitted to the remote monitoring center through the wireless communication module 24 (such as GPRS, LoRa, etc.), and the management personnel can view the running status, parameters and alarm information of the system in real time through terminal devices such as mobile phones and computers.

[0044] In the above system, through the setting of the first flow valve 5, the opening degree can be automatically adjusted according to the instructions of the intelligent control system to ensure the stable operation of the system under different working conditions. Through the control of the second flow valve 6, the water supply amount of other hydraulic ram pumps 3 can also be quickly adjusted to make up for the insufficient water supply of the faulty hydraulic ram pump 3 and ensure the stable operation of the water level in the water storage tank 1 and the power generation system.

[0045] As an embodiment for further elaboration:

[0046] A water quality purification device 7 is arranged at the front end of the water inlet pipe or at the inlet of the hydraulic ram pump 3. The water quality purification device 7 includes any one or more of a filter screen, a sedimentation tank, and an activated carbon filter. The filter screen can intercept larger sediment and impurities, the sedimentation tank can let sediment and the like settle down and be cleaned regularly, and the activated carbon filter can adsorb organic matters, microorganisms and peculiar smells in the water to improve the water quality.

[0047] Embodiment 2

[0048] On the basis of Embodiment 1, multiple groups of hydraulic ram pumps 3 can be set as required. Taking four groups as an example, the four groups of hydraulic ram pumps 3 have the following connection methods:

[0049] A. Each group of hydraulic ram pumps 3 is connected to the water storage tank 1 through the second flow valve 6.

[0050] Each group of hydraulic ram pumps 3 has an independent power source and is connected to the water storage tank 1 through its respective second flow valve 6 to realize the function of lifting water to the water storage tank 1. The second flow valve 6 can play a role in controlling the water delivery flow rate and pressure of each group of hydraulic ram pumps 3 to the water storage tank 1 to ensure the stable operation of the system.

[0051] Each group of hydraulic ram pumps 3 can precisely control the water supply volume and pressure to the water storage tank 1 through independent flow valves, and flexibly adjust the working state of each group of hydraulic ram pumps 3. For example, in different time periods or different water flow conditions, the flow valve of a certain group of hydraulic ram pumps 3 can be adjusted separately to meet the water level control and power generation requirements of the water storage tank 1.

[0052] When a certain group of hydraulic ram pumps 3 needs to be maintained or overhauled, only the corresponding flow valve needs to be closed, without affecting the normal operation of other groups of hydraulic ram pumps 3, improving the maintainability and reliability of the system. Since each group of hydraulic ram pumps 3 is relatively independent, when one group of hydraulic ram pumps 3 fails, other groups of hydraulic ram pumps 3 can still work normally, without causing the entire system to break down.

[0053] B. Multiple hydraulic ram pumps 3 are connected in series.

[0054] Multiple hydraulic ram pumps 3 are connected in sequence. The water outlet of the previous hydraulic ram pump 3 is connected to the water inlet of the next hydraulic ram pump 3. The water flow passes through each hydraulic ram pump 3 in sequence, and the pressure of the water will further increase after passing through each hydraulic ram pump 3.

[0055] In this case, it is suitable for scenarios where water needs to be lifted to a relatively high height. For example, when lifting water into a water storage tank 1 that is more than ten meters or even higher, the series-connected hydraulic ram pumps 3 can gradually increase the water pressure, so as to meet the requirement of lifting water to the specified height.

[0056] C. Multiple hydraulic ram pumps 3 are connected in parallel.

[0057] The water inlets and outlets of multiple hydraulic ram pumps 3 are connected in parallel respectively. The water flow enters each hydraulic ram pump 3 simultaneously, and then flows out from the water outlets of each hydraulic ram pump 3.

[0058] The above operation can transport a large amount of water in a relatively short time, improving the water supply capacity of the system. In some occasions with large water volume requirements, the water volume can be met. Since the working pressure of each hydraulic ram pump 3 is relatively independent, the parallel connection method is difficult to significantly increase the water pressure like the series connection. Therefore, it is not very suitable for scenarios where water needs to be lifted to a very high height.

[0059] The above three connection methods can be selected according to the specific usage scenarios. Which connection method to specifically adopt depends on the actual application requirements and system design objectives.

[0060] Embodiment 3

[0061] The 4 - group system of the tower - type water kinetic generator provided by the present invention can be applied in remote mountainous areas and ecologically sensitive areas in southern China.

[0062] Taking a specific embodiment as an example, assume that the system is built on a river with a flow rate of 2.5 L / s and a flow velocity of 9 cubic meters per hour.

[0063] There is a collecting tank with a drop of more than one meter at the river. This collecting tank is located downstream of the waterfall or at the ditch or embankment. If it does not exist, manual excavation is carried out to achieve the water hammer effect, and the hydraulic ram pump 3 is placed in the collecting tank.

[0064] Build a water storage tank 1 with a capacity of 10000L at a suitable position above the river. The full-load design weight (including the water storage tank 1) is 11000 kg. The water storage tank 1 is fixed by a tower about 10 meters high. The total full-load weight (including the iron tower) is 15000 kg. The iron tower is made of angle iron with a corresponding thickness and is assembled by drilling using the triangle principle (for easy disassembly). The water storage tank 1 can be made of iron or aluminum, or industrial waste without residue can also be used. It can be installed at the top of the tower or fixed to the bottom surface that meets the height requirement.

[0065] Taking four RZ50-type hydraulic ram pumps 3 as an example, the inlet pipe diameter of the hydraulic ram pump 3 is 50MM, and the outlet pipe diameter is 15MM. Four hydraulic ram pumps 3 are connected in series. The water storage tank 1 is connected to the river through the hydraulic ram pumps 3 composed of four RZ50-type hydraulic ram pumps 3 connected in series, and it can fill a 10-cubic water tank in 20 - 22 minutes.

[0066] A pipeline is connected between the bottom of the water storage tank 1 and the generator 4. The generator 4 uses an oblique impact generator with a rated power of 0.75Kw, and the designed flow rate is 0.01 - 0.02M 3 / s. Four groups of generators 4 are connected in parallel, and it can drain 10 cubic meters of water and generate 1 degree of electricity every 20 minutes. This set of configuration is the most basic configuration, which can generate 3 degrees of electricity per hour, 72 degrees of electricity per 24 hours. Every 4 pipelines and 4 generators 4 form a module, and multiple modules can be connected in parallel. The designed water discharge adopts a tree-shaped pipe network. For example, the main pipeline is 80mm, and the branch pipeline is 50mm. A flow control valve is used in synchronization to achieve high-power generation in synchronization.

[0067] At the same time, an overflow valve 11 is installed on the top of the water storage tank 1, and a liquid level gauge and a flow meter 22 are installed in the water storage tank 1.

[0068] During the actual operation process, the river water is lifted to the water storage tank 1 by the hydraulic ram pump 3 for storage. When power generation is required, the water in the water storage tank 1 flows into the generator 4 to drive the generator 4 to generate electricity. The intelligent control system monitors parameters such as water level and flow rate in real time, and automatically adjusts the opening degree of the flow valve according to the monitoring results to control the output power of the generator 4.

[0069] The procurement cost of each RZ50 type hydraulic ram pump 3 is 4,500 yuan, and for four units it is 18,000 yuan. The procurement cost of a 0.75KW tangential flow generator 4 is about 5,000 yuan, and for four units it is 20,000 yuan. The cost of a 10-meter iron tower is about 50,000 yuan. The cost of the water storage tank 1 is about 20,000 yuan. The costs of pipelines + filtration equipment + flow control equipment + construction labor, etc. are about 50,000 yuan. The design cost of the whole set of equipment is between 158,000 yuan and 160,000 yuan.

[0070] After actual testing, under normal operating conditions of the system, the daily power generation is 72 degrees. Calculated according to the local electricity price of 0.48 yuan per degree, a single-module unit can generate an economic benefit of 345.6 yuan per day. Under ideal conditions, working 250 days a year, it can generate an economic benefit of 207,360 yuan per year.

[0071] The operating principle of the 4 groups of tower-type water kinetic generators provided in this application is simple, with low investment and maintenance. It can recover the cost in the year of investment, has low requirements for the environment, and any tributary of the main river can be used as a production scenario for production. It is a product that makes full use of the natural environment to serve humanity. The generation and operation of the 4 groups of generators only utilize the water hammer effect generated by the water head drop to further raise the water head drop to serve humanity. In addition to power generation, the practical working scenario can also be used for life scenarios such as farmland irrigation. The water is in the pipeline throughout the power generation process and is returned to the river after power generation, without any environmental pollution or noise pollution. It is suitable for use in ecologically sensitive areas or for long-term field operation of work teams. The daily electricity consumption of rural families in China is about 3 kilowatts. In villages in remote mountainous areas, the daily workload of a single-module unit can meet the daily electricity needs of 70 families with no less than 200 people. If multiple modules operate simultaneously, they can be connected to the national power grid to transmit electricity and earn profits. Of course, it is still mainly to solve the electricity consumption in remote mountainous areas and ecologically sensitive areas.

[0072] Embodiment 4

[0073] In order to avoid the intermittency and instability of hydropower generation, on the basis of the above system, an energy storage device such as a battery pack can also be added.

[0074] When the power generation of the generator 4 is large, the excess electric energy is stored in the energy storage device; when the power generation is insufficient or the system stops generating electricity, the energy storage device can release the stored electric energy to supply power to the load, ensuring the stability and continuity of power supply.

[0075] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the gist of the present invention, they shall fall within the protection scope of the present invention.
