Description

Technical Field

[0001] The invention relates to the technical field of hydropower generation, in particular to a liftable hydropower generation device. Background Art

[0002] As a renewable energy source, hydropower has long been widely used around the world. Traditional hydropower generation devices usually rely on stable water flow, converting the kinetic energy of the water flow into mechanical energy through a fixed turbine, and then converting the mechanical energy into electrical energy through a generator. However, the hydropower generation devices in the prior art have some significant deficiencies in practical applications, especially when facing large changes in water levels in natural environments.

[0003] First, most existing hydroelectric power generation devices adopt a fixed installation design. The turbines and power generation devices are usually fixed at a certain height and cannot be adjusted according to the changes in water levels. In rivers and waterways, water levels often fluctuate significantly due to seasonal changes. In the dry season, the water level drops and the turbines may not be able to access enough water flow, resulting in a significant reduction in power generation efficiency or even failure to work properly; and during the flood season or floods, the high water level may cause damage to the fixed power generation equipment, further affecting the stability and safety of the power generation system.

[0004] Secondly, in the prior art, the maintenance and operation of hydroelectric power generation devices are relatively complicated. Traditional turbines and power generation systems usually adopt an integrated structural design. Once a component fails, the maintenance of the entire system is difficult, and it is often necessary to shut down and disassemble the entire device for inspection and repair. This not only increases maintenance costs, but may also cause the equipment to shut down for a long time, affecting the continuity of power supply. In addition, turbines are usually susceptible to debris in the water (such as branches, stones, and garbage, etc.), which may get stuck in the impeller of the turbine, causing the turbine to fail to operate normally. The existing device lacks a convenient filtering and cleaning system, which requires operators to frequently clean the turbine manually, increasing labor intensity.

[0005] Thirdly, many traditional hydroelectric devices are not designed with full consideration of environmental diversity and adaptability. These devices are usually complex in structure, high in manufacturing cost, and have high installation and operation requirements, making them unsuitable for promotion and application in areas with limited resources or harsh conditions. Especially in rivers or waterways with large seasonal water level changes, existing hydroelectric devices are difficult to ensure long-term stable power generation and are easily affected by the external environment, reducing the reliability and practicality of the devices.

[0006] To this end, those skilled in the art provide a liftable hydroelectric power generation device to solve the problems raised in the above background technology. Summary of the invention

[0007] In view of the deficiencies of the prior art, the present invention provides a liftable hydroelectric power generation device, which solves the problems of reduced efficiency, inconvenient maintenance and poor adaptability of the existing hydroelectric power generation devices due to water level changes.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: A liftable hydroelectric power generation device, comprising:

[0009] The base has a protrusion on one side and is rectangular in shape, and is used to install other components and provide support;

[0011] The lifting device comprises a fixed pier, a first lifting shaft, a second lifting shaft, a buckle, a lifting screw shaft and a matching knob, the lifting screw shaft controls the up and down position of the lifting device through the knob, and the buckle on the fixed pier is used to fix the first lifting shaft and the second lifting shaft;

[0012] The power generation system includes a power generation device, which is installed on the lifting system and one end of which is connected to the runner;

[0013] Connecting piece, used to connect the power generation system and the lifting system.

[0015] Preferably, the filter is installed on the outside of the water turbine through a mosaic structure, located at the quartered position of the water turbine, and connected to the filter tank to filter debris in the water.

[0016] Preferably, the impeller comprises a first turntable, a second turntable and a turntable belt, wherein the turntable belt connects the first turntable and the second turntable for transmitting mechanical energy to the power generation device when the turbine rotates.

[0017] Preferably, the lifting device is connected to the power generation device via a connecting member, and the connecting member includes an embedded rotating shaft interface, which is used to connect the outer rotating shaft and the inner rotating shaft to transmit the rotation of the inner rotating shaft.

[0018] Preferably, the water turbine is composed of an impeller, a horizontal bar and a snap-on slot, the impeller is located at the center of the horizontal bar, the horizontal bar is connected to the base through a guide rail, and the snap-on slot is used to fix and remove the filter.

[0019] Preferably, the filter tank is connected to an outer rotating shaft, the outer rotating shaft is further connected to an inner rotating shaft, the inner rotating shaft is connected to a power generation device via a rotor, and the outer rotating shaft, the inner rotating shaft and the rotor are all installed on a base.

[0020] Preferably, the filter comprises a mesh shell, a filter screen and a main shell, wherein the filter screen is semicircularly surrounded on the main shell, the mesh shell is fixedly installed at both ends, and the main shell is connected to the snap-on slot of the turbine through a slot.

[0021] Preferably, a fixed pier is provided on the base, and the fixed pier fixes the first lifting shaft and the second lifting shaft respectively through buckles fixed on the left and right sides of the structural bottom plate, and fixes the lifting screw shaft through the middle buckle, and the lifting screw shaft controls the up and down position of the lifting system through a knob.

[0022] Working principle: During operation, when water flows into the device, the impurities in the water are first filtered out by the filter embedded in the outer side of the turbine to ensure the normal operation of the turbine. The filtered water flows into the impeller of the turbine, causing the impeller to start rotating. The impeller is fixed on the horizontal bar, which is connected to the base through the guide rail to ensure that the turbine can operate stably. As the turbine rotates, the mechanical energy is transmitted to the inner shaft through the outer shaft, and further transmitted to the generator through the runner. The runner consists of a first turntable, a second turntable and a runner belt connecting the two. When the turbine rotates, the runner belt transmits the rotational motion to the generator, so that the generator converts the mechanical energy into electrical energy through the internal magnetic flux line cutting process and outputs electricity.

[0023] Under different water level conditions, the lifting device adjusts the height of the lifting screw shaft through the matching knob, so that the power generation system as a whole can be lifted and lowered with the water level. The fixed pier firmly fixes the first lifting shaft and the second lifting shaft through the buckle, and the lifting system and the power generation system are tightly connected through the connector, ensuring that the system maintains structural stability while adjusting the height, and ensuring that the power generation device can operate efficiently under different water levels. When maintenance or cleaning is required, the filter can be easily removed from the turbine through the buckle slot for cleaning or replacement. At the same time, the design of the entire device makes it easy to disassemble and reinstall the connections between the components (such as the connection between the outer shaft and the inner shaft, and the connection between the power generation system and the lifting system), so as to achieve convenient maintenance and continuous and efficient operation of the device.

[0024] The present invention provides a liftable hydroelectric power generation device having the following beneficial effects:

[0025] 1. The present invention can flexibly adjust the height of the turbine and the power generation system according to the change of water level through the design of the lifting system, and can be used in rivers with different water levels, eliminating the defect of low efficiency of the hydroelectric power generation device caused by the fluctuation of the water level, so that the utilization efficiency of the water power is significantly improved.

[0026] 2. The present invention adopts modular design, especially in the connection of filter, turbine, lifting system and power generation system, through the snap-on slot and interlocking structure, the components can be easily disassembled and replaced. This not only simplifies daily maintenance and cleaning work, but also reduces maintenance costs and improves the service life and reliability of the device.

[0027] 3. The filter provided by the present invention can effectively filter the debris in the water and prevent the debris from entering the turbine, thereby preventing the turbine from being blocked or damaged by the debris and affecting the normal operation of the power generation device. The disassembly design of the filter also makes it very convenient to clean and replace it, further ensuring the long-term stable operation of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example:

[0036] Please see attached Figure 1The embodiment of the present invention provides a liftable hydroelectric power generation device, which includes a base 5, a lifting system, a power generation system, a connector 203 and other auxiliary components. The base 5 is rectangular as a whole, and a protruding structure is provided on one side thereof to enhance the stability of the device and provide installation support for other components. The base 5 supports the entire device through a structural bottom plate 207, and a plurality of buckles 202 are provided on the structural bottom plate 207 to fix the first lifting shaft 206 and the second lifting shaft 208 of the lifting system to ensure the stability of the lifting system when adjusting the height.

[0037] Please see attached Figure 1 -Attached Figure 2 The lifting system includes a lifting device 8, the core components of which are a lifting screw shaft 205 and a matching knob 201. The knob 201 is mounted on the lifting screw shaft 205 and is used to control the up and down position adjustment of the lifting device 8. When the water level changes, the operator can drive the lifting screw shaft 205 to rise or fall by rotating the knob 201, thereby driving the height change of the entire power generation system to ensure that the turbine 1 can always be in the optimal water flow position. In addition, a fixed pier is also provided in the lifting device 8, and the fixed pier fixes the first lifting shaft 206 and the second lifting shaft 208 respectively through the buckle 202, so that the lifting system maintains good stability and reliability when adjusting the height.

[0038] Please see attached Figure 3 -Attached Figure 4 The power generation system mainly includes a turbine 1, a filter 2, a filter tank 3, an outer rotating shaft 4, an inner rotating shaft 6, a runner 7 and a power generation device 9. When the water flows into the device, it first passes through the filter 2 embedded in the outer side of the turbine 1, located at the four-equal position of the turbine 1, and connected to the filter tank 3. The filter 2 is used to filter the debris in the water to prevent the debris from entering the turbine 1 and ensure the normal operation of the turbine 1. After the water flows through the filter 2, it impacts the impeller 302 of the turbine 1, and the impeller 302 starts to rotate. The impeller 302 is fixed on the horizontal bar 301, and the horizontal bar 301 is connected to the base 5 through a guide rail. The rotation of the turbine 1 is transmitted to the inner rotating shaft 6 through the outer rotating shaft 4, and further transmitted to the power generation device 9 through the runner 7.

[0039] Please see attached Figure 5 The runner 7 includes a first rotating disc 501, a second rotating disc 503 and a runner belt 502 connecting the two. When the turbine 1 rotates, the runner belt 502 transmits the rotational motion to the generator 9, so that the generator 9 converts mechanical energy into electrical energy through the internal magnetic flux line cutting process, and finally outputs electricity for external use.

[0040] The filter 2 is composed of a mesh housing 401, a filter screen 402 and a main housing 403. The filter screen 402 is semicircularly surrounded on the main housing 403. The mesh housing 401 is fixedly installed at both ends. The main housing 403 is connected to the snap-on slot 303 of the turbine 1 through a slot. The filter 2 is used to filter debris in the water to prevent the debris from entering the turbine 1 and ensure the normal operation of the turbine 1.

[0041] Please see attached Figure 3 -Attached Figure 4 , the device is designed with convenient disassembly and maintenance functions, especially in the components of the filter 2 and the lifting system. In order to facilitate the cleaning of the turbine 1 and the filter 2, the filter 2 adopts a snap-on slot 303 installation structure, which can be removed from the turbine 1 through simple operation for cleaning or replacement. At the same time, the power generation system and the lifting system are connected through a connector 203, and the connector 203 includes an embedded shaft interface 204, which is used to connect the outer shaft 4 with the inner shaft 6 and ensure smooth transmission. The modular design of the connector 203 allows the power generation system to be easily separated from the lifting system, which is convenient for the maintenance and inspection of the power generation device 9 and the lifting device 8.

[0042] The device is particularly suitable for environments with seasonal water level changes such as rivers and waterways, such as the tributary areas of the middle and lower reaches of the Yangtze River. The water flow speed in these areas is relatively fast, but the water level changes frequently. Through the lifting function of the present invention, the device can adjust its height accordingly according to the water level, ensuring that it can maintain efficient power generation capabilities during dry seasons or floods. In addition, the portable and detachable design of the device makes it easy to install and remove in different locations, suitable for temporary power generation or emergency power generation needs.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
