Description

Technical Field

[0001] The present invention relates to the technical field of water energy power, and more specifically, to a water energy power output device. Background Art

[0002] Water energy is a clean energy, green energy, and renewable energy, mainly used for hydroelectric power generation. The advantages of hydroelectric power generation are low cost, continuous renewable, and pollution-free. The disadvantage is that its distribution is greatly restricted by natural conditions such as hydrology, climate, and landforms, and is easily affected by factors such as terrain and climate.

[0003] Water energy power output equipment refers to equipment that uses water resources such as water flow, tide or water pressure to generate power. This type of equipment can convert the potential energy of water into kinetic energy for power output. In order to make the most direct use of the output power, the output power can be combined with power generation equipment to form hydropower generation equipment. Existing large-scale hydropower generation equipment mainly builds hydropower generation facilities in corresponding waters, uses natural water flow or artificially constructed channels to guide water flow through the turbine, and the water flow impacts the turbine blades to make them rotate, and the turbine drives the generator to operate, which in turn drives the rotor inside the generator to rotate, thereby generating electricity. For large-scale power generation facilities, they can be connected to the power grid through substation equipment, or they can be connected to energy storage devices to store electricity according to demand.

[0004] However, for some smaller rivers, mountains and other areas, or some outdoor emergency endurance stations, it is impossible to build large-scale fixed power generation facilities. Therefore, in order to facilitate the movement of equipment and adapt to more usage scenarios, many small power generation equipment have been designed based on the above-mentioned power generation principle. Although such equipment is small in size and has limited power generation capacity, it can stabilize the power output by using corresponding controllers, power small electrical devices such as mobile phones and lighting fixtures, and can also be connected to batteries for energy storage.

[0005] For the above-mentioned small hydroelectric power generation equipment, in order to reduce the volume and facilitate mobility, a large number of structures need to be reduced, and only the power cylinder (housing), turbine body, small generator and related necessary structures are retained. However, the power generation principle is basically the same. Since small hydroelectric power generation equipment does not require the establishment of related infrastructure and fixed support equipment, the above-mentioned small equipment can be directly placed in the water flow in actual use, pulled by ropes, or simply fixed with other simple fixing equipment. It is only necessary to ensure that the equipment is completely placed in the water and that water flows through the turbine inside the equipment.

[0006] In order to improve the utilization of the kinetic energy of flowing water and reduce the obstruction of flowing water, the above-mentioned small hydroelectric power generation equipment is usually designed as a straight-through structure, that is, the water flows directly through the turbine structure in the equipment along its flow direction. For hydroelectric power generation equipment, the greater the river water flow rate, the more energy is converted. However, when the water flow is too large, the kinetic energy of the debris carried in the water (such as garbage, stones formed by excessive impact, corpses of small animals such as fish, etc.) is relatively large. Directly flowing into the equipment or colliding with the equipment will cause certain damage to the equipment, especially when it is stuck in the turbine, it will seriously affect the rotation efficiency of the turbine and even cause the turbine to get stuck, reducing the power conversion efficiency of the equipment. Summary of the invention

[0012] In a preferred embodiment, the impact cover is composed of a plurality of elastic rods, the plurality of elastic rods are distributed in a cone shape, and the outer curved portion is a curved structure at the tail end of the elastic rod.

[0013] In a preferred embodiment, an elastic strip is fixedly connected to the filter cover corresponding to the elastic rod, one end of the elastic strip close to the center of the impact cover is fixedly connected to the impact cover, and an elastic connecting piece is arranged between the elastic strip and the elastic rod, and the elastic connecting piece is used to provide elastic force to the elastic rod toward the outside of the impact cover.

[0014] In a preferred embodiment, a pull rod is slidably installed at the center of the impact cover, a traction connection structure is fixedly installed on the pull rod, an end of the pull rod away from the traction connection structure is fixedly connected to a fixing rope, an end of the fixing rope away from the pull rod is fixedly connected to a support ring, and an elastic reset member is arranged between the pull rod and the impact cover, and the elastic reset member is used to provide an elastic force to the impact cover in a direction away from the support ring.

[0015] In a preferred embodiment, a vertical rotation plate is installed at the bottom of the power cylinder, a counterweight structure is fixedly connected to the bottom end of the vertical rotation plate, and a plurality of wing plates are also arranged outside the power cylinder.

[0016] In a preferred embodiment, a swivel is rotatably mounted on the outside of the power cylinder, the wing plate is mounted on the swivel, and a fastening structure for fixing the swivel is provided between the swivel and the power cylinder.

[0020] The beneficial effects of the present invention are as follows: under the action of the filter cover, the present invention can block and filter most of the debris and prevent it from moving into the power cylinder. Secondly, the debris can rebound when it collides with the impact cover, so that the debris with greater kinetic energy can deviate from the original movement path. Even if the water flow is slow and the kinetic energy of the debris is small, it can move backward along the surface of the impact cover. The taper of the impact cover is greater than that of the filter cover. Therefore, during the movement, the debris tends to move away from the filter cover, thereby effectively protecting the power conversion component, ensuring the power conversion efficiency of the power conversion component, and ensuring the stability of the equipment operation. Moreover, since the filter cover is distributed in a cone shape, the filtered debris will gradually move backward under the impact of the external water flow, which can prevent the debris from accumulating outside the filter cover to form a blockage.

DETAILED DESCRIPTION

[0036] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0037] Refer to the instruction manual Figures 1 to 14 A water energy power output device includes a power conversion component 1, a small generator 2 is arranged at the output end of the power conversion component 1, the power conversion component 1 includes a power cylinder 11, a turbine 12 is rotatably installed inside the power cylinder 11, an output shaft 13 is connected to the turbine 12, a docking mounting sleeve 111 is arranged on the power cylinder 11, the small generator 2 is detachably installed in the docking mounting sleeve 111 (for example, the small generator 2 is fixed with bolts), and the output shaft 13 is detachably connected to the input shaft of the small generator 2 (for example, a coupling is used to connect or a slot is set in the output shaft 13, and a plug structure is set on the input shaft of the small generator 2, and the detachable connection between the two is achieved by plugging the plug and the slot).

[0038] The input end of the power conversion assembly 1 is provided with a support ring 3, a guide cover 4 is connected between the support ring 3 and the power conversion assembly 1, a filter cover 5 is installed on the side of the support ring 3 away from the guide cover 4, and an impact cover 6 is fixedly connected to the end of the filter cover 5 away from the support ring 3, wherein the guide cover 4 and the filter cover 5 are both conical structures, the guide cover 4 is gradually reduced in diameter in the direction close to the power conversion assembly 1, and the filter cover 5 is gradually reduced in diameter in the direction away from the power conversion assembly 1, and the impact cover 6 is provided with a traction connection structure 61 (such as a lifting ring, using a rope) for connecting to a traction device. The rope is connected to the traction connection structure 61, and the rope is fixed on the shore, and the traction connection structure 61 is pulled by the rope). It should be noted that the deflector 4 is made of waterproof material, and the deflector 4 and the filter cover 5 can both use soft structures, and the deflector 4 can be connected to the input port of the power cylinder 11 by bolts or tie ropes and other structures, that is, the deflector 4 and the power cylinder 11 can be disassembled, and the deflector 4 and the filter cover 5 are fixedly connected to the support ring 3, so that the deflector 4, the support ring 3 and the filter cover 5 can form a storage bag structure to store the remaining structure of the equipment.

[0039] The impact cover 6 is a conical structure, the taper of the impact cover 6 is greater than the taper of the filter cover 5 , and an outwardly expanded outer curved portion 601 is provided at the edge of the impact cover 6 .

[0040] In the above embodiment, in actual use, the impact cover 6 is at the front end of the entire device and contacts the water flow first. First, under the action of the filter cover 5, most of the debris can be blocked and filtered to prevent it from moving into the power cylinder 11. Secondly, the water flow passing through the filter cover 5 is guided by the guide cover 4 and flows into the power cylinder 11 in a concentrated manner, which can increase the conversion and utilization of the kinetic energy of the water. After the equipment is arranged, the impact cover 6 and the power conversion component 1 are on the same axis. When the debris in the water flow near the axis area of ​​the power conversion component 1 approaches the equipment, it will first contact the impact cover 6, collide with the impact cover 6, and rebound, which can cause the debris with greater kinetic energy to deviate from the original movement path, thereby reducing the debris. The phenomenon of debris impacting the power cylinder 11, even if the water flow is slow and the kinetic energy of the debris is small, it can move backward along the surface of the impact cover 6, and the taper of the impact cover 6 is greater than the taper of the filter cover 5. Therefore, during the movement, the debris has a tendency to move away from the filter cover 5, especially after the debris contacts the outer bend 601, it can also increase the tendency to move outward, thereby improving the effect of the debris away from the filter cover 5, thereby achieving effective protection of the power conversion component 1, ensuring the power conversion efficiency of the power conversion component 1, and ensuring the stability of the equipment operation. Moreover, since the filter cover 5 is distributed in a cone shape, the filtered debris will gradually move backward under the impact of the external water flow, which can avoid the accumulation of debris outside the filter cover 5 to form an obstruction.

[0041] Further, in order to improve the effect of water flow passing through the power cylinder 11, and to increase the elasticity of the impact cover 6 itself, and to prevent debris from impacting the impact cover 6 and causing it to shake too much, this embodiment also provides the following technical solutions, for details, refer to the attached manual Figures 4 to 6 The impact cover 6 is composed of a plurality of elastic rods 602 , and the plurality of elastic rods 602 are distributed in a cone shape (ie, a cover structure with gaps formed by rotating in an axis line), and the outer curved portion 601 is a curved structure at the tail end of the elastic rod 602 .

[0042] Through the above-mentioned improvements to the impact cover 6, firstly, a gap is formed on the impact cover 6 through which water can flow. Secondly, the elasticity of the elastic rod 602 is increased. When debris hits, it can form a good buffer for the impact cover 6 as a whole, reducing the shaking amplitude of the impact cover 6. Secondly, when the elastic rod 602 rebounds, it can also form a unilateral outward push on the debris, thereby increasing the reverse impact effect on the debris. When the debris collides, it only contacts part of the elastic rod 602, causing the elastic rod 602 that it contacts to deform, while other elastic rods 602 are not affected. Therefore, the overall relative stability of the impact cover 6 is relatively high.

[0043] Furthermore, in the above embodiment, although most of the debris will move backward along the surface of the filter cover 5 under the influence of the water flow, some structures with complex shapes or plants with more roots and leaves are easy to be connected with the filter cover 5. In order to improve the efficiency of removing debris, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Figure 5 and Figure 6 An elastic strip 65 is fixedly connected to the filter cover 5 at the elastic rod 602. One end of the elastic strip 65 close to the center of the impact cover 6 is fixedly connected to the impact cover 6. An elastic connector 651 is arranged between the elastic strip 65 and the elastic rod 602. The elastic connector 651 is used to provide an elastic force to the elastic rod 602 toward the outside of the impact cover 6, such as a spring structure.

[0044] In actual use, the elastic pressure strip 65 and the elastic connector 651 can increase the elastic buffering effect of the single elastic rod 602. Secondly, when hit by debris, the elastic connector 651 will transmit part of the impact force and cause the filter cover 5 to vibrate, thereby improving the effect of clearing external debris.

[0045] Furthermore, a pull rod 62 is slidably installed at the center of the impact cover 6, and the traction connection structure 61 is fixedly installed on the pull rod 62. The end of the pull rod 62 away from the traction connection structure 61 is fixedly connected to a fixing rope 63, and the end of the fixing rope 63 away from the pull rod 62 is fixedly connected to the support ring 3. An elastic reset member 64 is arranged between the pull rod 62 and the impact cover 6, and the elastic reset member 64 is used to provide an elastic force, such as a spring, to the impact cover 6 in a direction away from the support ring 3.

[0046] In actual use, the rope is directly connected to the pull rod 62. Therefore, under the action of the reverse thrust of the deflector 4, the fixing rope 63 is straightened, and the impact cover 6, under the action of the elastic reset member 64, will also straighten the filter cover 5, so that the filter cover 5 is in a straightened state. When the impact cover 6 is impacted, the elastic force of the elastic reset member 64 can provide more sufficient buffering. At the same time, the impact cover 6 will also move relatively backward on the pull rod 62, thereby making the filter cover 5 fluffy. After the debris is removed, the elastic reset member 64 rebounds, the impact cover 6 is reset, and the filter cover 5 can be straightened again, so that the filter cover 5 shakes, further avoiding the debris from being hooked and gathered outside the filter cover 5, and ensuring the efficiency of water flow through the power cylinder 11.

[0047] In actual use, a rope is fixed on the shore, and the telescopic and traction connection structure 61 is connected, and then the entire device is thrown into the flowing water. Under the action of the water flow, the deflector 4 can be fully expanded to form a deflection structure, so that more water passes through the power cylinder 11. At the same time, the water flow will also form a thrust on the deflector 4, and cooperate with the traction of the rope to place the device relatively stably in the water. When the water flows through the power cylinder 11, it drives the turbine 12 to rotate, and then drives the output shaft 13 to drive the rotor of the turbine 12 to rotate to generate electricity (the small generator 2 has the same structure as the commonly used generator, and the other facilities it needs to be equipped with are also the commonly used technical solutions used in the power generation system, such as stabilizer, automatic voltage regulator AVR, rotor speed regulator, energy storage system, inverter, rectifier and intelligent control system, etc. Since the above technologies are all commonly used devices in the field of generator power generation, this embodiment will not be explained in detail). Among them, the wires of the small generator 2 can be connected to the shore together with the rope, and other equipment required for power generation such as energy storage devices (batteries) are set on the shore.

[0048] Refer to the instruction manual Figure 7 and Figure 8 If the operating environment conditions permit, rope structures can be set up on both sides to fully tow and fix the equipment. When fixing, the equipment needs to be completely immersed below the water surface. The overall equipment of this solution can be set relatively large, which is suitable for long-term use. If the use environment is limited, such as outdoor camping, emergency, etc., it is difficult to set up complete towing and fixing ropes on both sides. Only one set of towing ropes can be used for towing, but the power generation efficiency is reduced. However, this solution can make the equipment smaller, which is conducive to storage and carrying.

[0049] In the above embodiment, if the attached Figure 7 The equipment is relatively stable and will not shake much when hit by debris. However, if conditions are limited, only the attachment can be used. Figure 8 When the fixing method is shown, the overall stability of the device is relatively poor. To this end, this embodiment also provides the following technical solutions. For details, refer to the attached manual. Figures 9 to 13 A swivel plate 14 is installed at the bottom of the power cylinder 11, and a counterweight structure 141 is fixedly connected to the bottom end of the swivel plate 14. A wing plate 15 is also arranged outside the power cylinder 11. A swivel 152 is rotatably installed outside the power cylinder 11, and the wing plate 15 is installed on the swivel 152. A fastening structure (such as a fastening screw) for fixing the swivel 152 is arranged between the swivel 152 and the power cylinder 11, wherein the swivel plate 14 and the wing plate 15 are preferably detachably installed, and then when they are not needed, the swivel plate 14 and the wing plate 15 can be removed and connected together with the power conversion assembly 1. The wing plates 14 and the counterweight structure 141 are mainly used to keep the power conversion assembly 1 relatively stable in the vertical direction to prevent the power conversion assembly 1 from rotating as a whole. Secondly, in order to avoid the influence of the rotational kinetic energy generated by the rotation of the turbine 12 on the power conversion assembly 1, two sets of turbines 12 can be set at the same time, and the two sets of turbines 12 rotate in opposite directions to offset the rotational kinetic energy. Secondly, the position of each wing plate 15 can be adjusted according to the needs, as shown in the attached manual. Fig. 9 As shown, the stabilizing effect of the power conversion assembly 1 is improved by means of the guidance of the vertical plate 14 and the wing plate 15 in the water.

[0050] For further information, please refer to the attached manual. Fig. 9 and Fig.10 An airbag structure 151 is embedded in the wing panel 15, and an air filling and discharging nozzle is provided on the airbag structure 151, and a sealing cover is provided on the air filling and discharging nozzle. Therefore, when in use, the wing panel 15 can be inflated according to the overall weight of the equipment and the required diving height of the equipment to change the overall buoyancy of the equipment, thereby adjusting the use state of the equipment and improving the practicality of the equipment.

[0051] Further, in the attached manual Figure 8 When the device is fixed in the state shown, under the action of the water flow, the device tends to approach the shore, and the shore is shallow, and the water flow velocity is small, and the power conversion efficiency is low. For this reason, the present embodiment also provides the following technical solution: a docking seat 16 is fixedly connected to the bottom of the power cylinder 11, and a docking shaft 161 is provided on the docking seat 16. The docking shaft 161 is rotatably plugged with the swivel plate 14, and a fixing structure (such as a fixing screw) for fixing the swivel plate 14 is provided on the swivel plate 14.

[0052] When in use, the swivel plate 14 can be rotated to cause an inclination between it and the power cylinder 11. After being fixed, the swivel plate 14 can form a reverse thrust on the power cylinder 11 like a rudder. Fig.11, so that the device can be driven to approach the center of the river (the device will tilt slightly during the approach process) until the device, rope and inclined swivel plate 14 form a stable state, thereby allowing the device to stay as far away from the shore as possible.

[0053] It should be noted that in the above scheme, a plug structure can be used to quickly disassemble and install the wing plate 15 and the swivel ring 152. A positioning bead structure is provided in the plug, and a corresponding bolt structure can also be used. A socket that is plugged into the docking shaft 161 can be provided on the swivel plate 14, and the positioning bead structure can be used to achieve quick disassembly. In addition, other quick-disassembly structures can also be used.

[0054] For further information, please refer to the attached manual. Fig.12 and Fig.13 The present embodiment also provides another solution for keeping the equipment away from the shore. Specifically, a through hole 142 is provided in the middle of the vertical plate 14, and a reverse thrust impeller 8 is rotatably installed inside the through hole 142. A shroud 81 is fixedly connected to the reverse thrust impeller 8, and a plurality of groups of radial blades 82 are fixedly connected to the outside of the shroud 81. A guide boss 143 is provided at a position of the reverse thrust impeller 8 on the outside of the vertical plate 14, and both ends of the guide boss 143 are set to triangular structures. The guide boss 143 is arranged to surround the shroud 81, and a notch 144 is provided at a position of the top of the guide boss 143 corresponding to the radial blade 82.

[0055] During actual use, the lateral flow of river water flows through the surface of the vertical plate 14, and under the action of the end of the guide boss 143, the lateral flow will not directly pass through the rotation center of the reverse thrust impeller 8, but will be separated by the guide boss 143, wherein the upper lateral flow flows backward along the upper area of ​​the guide boss 143, and cooperates with the radial blade 82 when flowing through the notch 144, driving the circumferential cylinder 81 to rotate, thereby rotating the reverse thrust impeller 8, and when the reverse thrust impeller 8 rotates, it will provide a longitudinal driving force perpendicular to the turbine 12 to the wing plate 15 like a propeller, and with the help of the above-mentioned power, the equipment can tend to move away from the shore.

[0056] It should be noted that two sets of docking structures docked with the docking shaft 161 can be set on the swivel plate 14. In actual use, the installation and matching direction of the swivel plate 14 and the power conversion assembly 1 can be replaced, thereby changing the thrust direction generated by the reverse thrust impeller 8 when driven by water flow.

[0057] The above solutions are only some simple fixing solutions provided in this embodiment. If there are other requirements, corresponding long-term fixing structures can be built in the water in advance to fix the equipment in the corresponding area.

[0058] The power conversion assembly 1 used as a power conversion can not only generate power in cooperation with the small generator 2, but also be directly connected to the device to drive the device to rotate. Fig.14 When in use, the small generator 2 is not connected, the output shaft 13 is docked with the flexible shaft 7, and the flexible shaft 7 is connected to the shore and directly docked with the use equipment, such as connecting the rotating shaft of the fan structure to directly drive the fan.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
