Description

Technical Field

[0001] The present invention relates to the technical field of hydroturbine equipment, and particularly to an energy-saving cooling tower hydroturbine and a control system. Background Art

[0002] Forced-draft cooling towers utilize the principle of convective flow to provide air circulation. Forced-draft cooling towers are usually very tall to induce sufficient air circulation, and they are also expensive to construct and are only used in applications that require continuous large-scale cooling for many years, such as thermal power plants. When air passes through the cooling tower packing, its temperature rises, and due to the chimney effect, it rises to the top of the cooling tower and leaves the tower. The air at the top draws in more air at the bottom of the tower, thus forming a natural air flow from the bottom to the top of the tower. As long as the cooling water circulates continuously, it can continue continuously.

[0003] Among them, when the hydroturbine changes from a stationary state to a rotating direction, due to the influence of the excessive mass of the top metal fan blades, during the startup process of the equipment, the mass of the metal fan blades will greatly limit the rotation efficiency of the hydroturbine in the early stage of startup. In view of the above problems, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an energy-saving cooling tower hydroturbine, including a driving mechanism, the interior of which has a space to provide space for the passage of high-pressure water bodies;

[0005] A cooling mechanism, fixedly installed on the top of the driving mechanism, and the rotational force generated by the driving mechanism drives the cooling mechanism to rotate;

[0006] A clamping mechanism, fixedly installed on the inner wall of the cooling mechanism, and provides a supporting force for the cooling mechanism when the rotation speed of the cooling mechanism is too fast;

[0007] Among them, during use, the driving mechanism is impacted by external water bodies and drives the cooling mechanism to rotate. When the rotation speed of the cooling mechanism is too fast, the clamping mechanism provides a clamping force for the cooling mechanism.

[0008] Preferably, the interior of the driving mechanism includes a housing, and a driving rod is rotatably connected to the inner wall of the through hole of the housing. The driving mechanism includes:

[0009] A driving component, arranged on the inner wall of the housing, for converting the impact force of external water bodies into the rotational force of the driving rod;

[0010] A circulation component, penetratingly arranged on both sides of the housing, and external water bodies are transmitted to the interior of the housing through the circulation component;

[0011] Among them, after the external water bodies reach the inside of the circulation component through the circulation component, the circulation component drives the driving rod to rotate.

[0012] Preferably, the cooling mechanism includes:

[0013] A fan blade assembly, which is fixedly arranged on the outer wall of the driving rod through a fixing member;

[0014] The fixing member includes a driving disk fixedly connected to the outer wall of the driving rod. A clamping frame is fixedly connected to the top of the driving disk. A fan blade frame is clamped and fixed at the inner wall of the clamping frame. A sliding groove is provided at the inner wall of the fan blade frame. The fan blade frame is set to be in a hollow state, effectively avoiding that when starting in the early stage, the fan blade frame rotates with too large contact area with the external air, resulting in an increase in the power required for the fan blade frame to start in the early stage;

[0015] A shielding assembly, which is slidably arranged at the inner wall of the sliding groove through a sliding member;

[0016] The sliding member includes an L-shaped sliding plate slidably connected to the inner wall of the sliding groove;

[0017] Among them, the L-shaped sliding plates are stacked together by a plurality of identical plates and are slidably connected to each other. The L-shaped sliding plates can be extended and completely block the inner wall of the sliding groove.

[0018] Preferably, the clamping mechanism includes:

[0019] A clamping assembly, which is fixedly installed at the bottom of the fan blade frame through a limiting member;

[0020] The limiting member includes two slide rails fixedly connected to the bottom of the fan blade frame. A slide rod is slidably connected to the inner walls of the two slide rails;

[0021] A pressure-receiving assembly, which is fixedly arranged at the inner wall of the sliding groove through a pressure-receiving member;

[0022] A fixing rod is fixedly connected between the two slide rods. A T-shaped sliding plate is fixedly connected to the top of the fixing rod;

[0023] Among them, when the L-shaped sliding plate extends outwards, it will drive the pressure-receiving assembly to operate synchronously. At this time, the pressure-receiving assembly will clamp and limit the bottom of the driving disk through the clamping assembly.

[0024] Preferably, the driving assembly includes a pressure-receiving fan blade fixedly connected to one end of the driving rod away from the driving disk. The outer wall of the pressure-receiving fan blade is slidably connected to the inner wall of the housing. A rotational speed sensor is fixedly arranged at the inner wall of the housing. The inner wall of the rotational speed sensor is rotatably connected to the outer wall of the driving rod. When cooling is required, external water source is transmitted into the housing through the water inlet pipe. At this time, the impact force generated by the high-pressure water body will act on the outer wall of the pressure-receiving fan blade, causing the pressure-receiving fan blade to drive the driving rod and the driving disk to rotate.

[0025] Among them, the external water body impacts the pressure-receiving fan blade, causing the pressure-receiving fan blade to drive the driving rod to rotate.

[0026] Preferably, the circulation component includes a water inlet pipe penetrating and connected to the side wall of the housing, and a water outlet pipe penetrating and connected to the side wall of the housing;

[0027] Among them, the external water body is transmitted to the inside of the housing through the water inlet pipe, and then discharged outwards through the water outlet pipe.

[0028] Preferably, the fan blade component includes a fixing block fixedly connected to one end of the fan blade frame away from the driving disc;

[0029] Among them, when the L-shaped sliding plate extends outwards, the corresponding L-shaped sliding plate will move towards the direction of the fixing block to complete the filling of the sliding groove;

[0030] The shielding component includes a first spring fixedly connected inside the L-shaped sliding plate. One end of the L-shaped sliding plate away from the clamping frame is fixedly connected with a counterweight block, and the outer wall of the counterweight block is slidably connected with the inner wall of the sliding groove;

[0031] Among them, when the fan blade frame rotates, the centrifugal force will force the counterweight block to slide outwards along the inner wall of the sliding groove and drive the L-shaped sliding plate to slide outwards;

[0032] Due to the characteristic that the counterweight block moves outwards under the influence of centrifugal force, after the counterweight block moves outwards, at this time, the counterweight components of the fan blade frame are dispersed to the overall peripheral part. At this time, the potential energy generated by the rotation of the counterweight block increases, and this potential energy will be converted into the thrust for the rotation of the fan blade frame, so that while the fan blade frame is subjected to the thrust of the high-pressure water body, the potential energy generated by the counterweight block will offset part of the resistance generated by the rotation, ensuring the rotation speed and efficiency of the fan blade frame.

[0033] Preferably, the clamping component includes a fixing frame fixedly connected to the bottom of the slide rail. A toothed rod is fixedly connected to the top of the fixing frame. A cylinder is rotatably connected to the inner wall of the slide rod. A torsion spring is sleeved on the outer wall of the cylinder. One end of the torsion spring away from the cylinder is fixedly connected with a prying rod. The side wall of the prying rod is rotatably connected with the side wall of the slide rod. One end of the cylinder away from the slide rod is fixedly connected with a first gear. The driving disc rotates synchronously through the fan blade frame, and the centrifugal force generated by the rotation will force the counterweight block to slide outwards along the inner wall of the sliding groove, so that the counterweight block can drive the L-shaped sliding plate to extend outwards;

[0034] Among them, when the counterweight block moves outwards, the side wall of the T-shaped sliding plate will contact the side wall of the T-shaped sliding plate, and the T-shaped sliding plate drives the slide rod to slide through the fixing rod;

[0035] As the internal impact force increases, the rotation speed of the fan blade holder continuously increases. At this time, the thrust generated by the outward sliding of the counterweight also increases accordingly. When the L-shaped slide completely covers the inner wall of the sliding groove, the side wall of the counterweight also contacts the side wall of the T-shaped slide. When the thrust generated by the counterweight increases, this thrust will force the T-shaped slide to move outward along the inner wall of the chute. The outward-moving T-shaped slide drives the slide bar to move along the inner wall of the slide rail in the direction of the second spring through the fixed rod. The slide bar will drive a number of cylinders to move outward synchronously. During this process, the first gear will roll along the outer wall of the rack. The rolling first gear will drive the cylinder to rotate counterclockwise. The cylinder drives the prying rod to rotate upward synchronously through the torsion spring, so that one end of the prying rod contacts the bottom of the L-shaped slide, causing the prying rod to move from Figure 8 to Figure 9 the state G in. Through the application of the above components, when the rotation speed of the fan blade holder increases, at this time, the prying rod will clamp and limit the bottom of the L-shaped slide, greatly reducing the vibration frequency generated when the L-shaped slide rotates.

[0036] Preferably, the pressure-receiving component includes a chute opened on the inner wall of the fixed block. The outer wall of the T-shaped slide is slidably connected to the inner wall of the chute. A second spring is fixedly connected to the side wall of the T-shaped slide. The end of the second spring away from the T-shaped slide is fixedly connected to the inner wall of the chute. In the early stage of equipment use, the L-shaped slides will be stacked near the center of the equipment. At this time, the counterweights of the equipment are mostly concentrated around the driving disk. Among them, the closer the counterweight is to the center position, the less power it needs to move, and the farther the counterweight is from the center position, the greater the power it needs to move. Therefore, the L-shaped slides and the counterweights are mostly stacked around the driving disk, greatly reducing the power required for the equipment to start in the early stage, and avoiding excessive deformation of the internally compressed fan blades due to excessive thrust for pushing the fan blades to rotate.

[0037] Among them, after the rotation speed decreases, as the centrifugal force decreases, the second spring will push the T-shaped slide to slide outward along the inner wall of the chute;

[0038] The design of the torsion spring enables, after some of the prying rods contact the bottom of the L-shaped slide, as the slide bar moves horizontally, at this time, the first gear will continue to rotate, and the torsional force generated by the rotation will be absorbed by the torsion spring. The torsion spring will generate an upward pushing force, forcing the other end of the prying rod to press more tightly against the bottom of the L-shaped slide. The above design enables different prying rods to adapt to L-shaped slides of different heights.

[0039] The control system of the energy-saving cooling tower water turbine includes the following steps:

[0040] S1: Rotation speed detection: Detect the rotation speed of the compressed fan blade through a rotation speed sensor installed on the inner wall of the housing. When the rotation speed of the drive rod is too slow or too fast, an electrical signal will be sent to the operation platform;

[0041] S2: Human-computer interaction: For the convenience of maintenance and operation, the staff need to monitor the data of the operation platform in real time, view the system parameters through the background, and receive fault alarm information.

[0042] The present invention has the following beneficial effects:

[0043] (1) Aiming at the problem that the weight of the fan blade is relatively large, resulting in excessive power required for startup, a cooling mechanism and a clamping mechanism are provided inside the device. The impact force generated by the high-pressure water body will act on the outer wall of the compressed fan blade, causing the compressed fan blade to drive the driving rod and the driving disk to rotate, so that the counterweight can drive the L-shaped slide plate to extend outward. Through the application of the above components, the closer the counterweight is to the center position, the less power is required for its movement, and the farther the counterweight is from the center position, the more power is required for its movement. Therefore, the L-shaped slide plate and the counterweight are mostly stacked around the driving disk, greatly reducing the power required for the initial startup of the device, and avoiding excessive thrust on the internal compressed fan blade due to pushing the fan blade to rotate, resulting in deformation.

[0044] (2) The present invention utilizes the increased thrust generated by the counterweight. The thrust will force the T-shaped slide plate to move outward along the inner wall of the chute. The outward-moving T-shaped slide plate drives the slide rod to move along the inner wall of the slide rail in the direction of the second spring through the fixed rod. The slide rod will drive a number of cylinders to move outward synchronously. During this process, the first gear will roll along the outer wall of the toothed rod. The rolling first gear will drive the cylinder to rotate counterclockwise. The cylinder drives the prying rod to rotate upward synchronously through the torsion spring, so that one end of the prying rod contacts the bottom of the L-shaped slide plate, causing the prying rod to change from the Figure 8 state to the Figure 9 state of G in the figure. When the rotation speed of the fan blade frame increases, at this time, the prying rod will clamp and limit the bottom of the L-shaped slide plate, greatly reducing the vibration frequency generated when the L-shaped slide plate rotates.

[0045] (3) The present invention sets the fan blade frame in a hollow state, effectively avoiding excessive contact area between the rotation of the fan blade frame and the external air during the initial startup, resulting in an increase in the power required for the initial startup of the fan blade frame. In addition, the design of the torsion spring enables, after some prying rods contact the bottom of the L-shaped slide plate, as the slide rod moves horizontally, at this time, the first gear will continue to rotate, and the torsional force generated by the rotation will be absorbed by the torsion spring. The torsion spring will generate an upward pushing force, forcing the other end of the prying rod to press more tightly against the bottom of the L-shaped slide plate. The above design enables different prying rods to adapt to L-shaped slide plates with different heights.

[0046] (4) The present invention utilizes the characteristic that the counterweight moves outward under the influence of centrifugal force. After the counterweight moves outward, at this time, the counterweight assembly of the fan blade frame is dispersed to the overall outer peripheral part. At this time, the potential energy generated by the rotation of the counterweight increases, and this potential energy will be converted into the thrust for the rotation of the fan blade frame, so that while the fan blade frame is subjected to the thrust of the high-pressure water body, the potential energy generated by the counterweight will offset part of the resistance generated by the rotation, ensuring the rotation speed and efficiency of the fan blade frame.

[0064] Among them, during use, the driving mechanism 1 is impacted by external water bodies and drives the cooling mechanism 2 to rotate. When the rotation speed of the cooling mechanism 2 is too fast, the clamping mechanism 3 provides a clamping force for the cooling mechanism 2.

[0065] The inside of the driving mechanism 1 includes an outer shell 13. The inner wall of the through hole of the outer shell 13 is rotatably connected with a driving rod 111. The driving mechanism 1 includes:

[0066] A driving component 11, the driving component 11 is arranged on the inner wall of the outer shell 13 and is used to convert the impact force of external water bodies into the rotational force of the driving rod 111;

[0067] The circulation component 12 is provided through both sides of the outer shell 13. The external water body is transmitted to the inside of the outer shell 13 through the circulation component 12;

[0068] Among them, after the external water body reaches the inside of the circulation component 12 through the circulation component 12, the circulation component 12 drives the drive rod 111 to rotate.

[0069] The cooling mechanism 2 includes:

[0070] The fan blade assembly 21 is fixedly arranged on the outer wall of the drive rod 111 through a fixing member;

[0071] The fixing member includes a drive disk 211 fixedly connected to the outer wall of the drive rod 111. A clamping frame 212 is fixedly connected to the top of the drive disk 211. A fan blade frame 213 is clamped and fixed at the inner wall of the clamping frame 212. A sliding groove 214 is formed at the inner wall of the fan blade frame 213. The fan blade frame 213 is set to be in a hollow state, effectively avoiding that when starting in the early stage, the rotation of the fan blade frame 213 has too large a contact area with the external air, resulting in an increase in the power required for the initial start of the fan blade frame 213;

[0072] The shielding component 22 is slidably arranged at the inner wall of the sliding groove 214 through a sliding member;

[0073] The sliding member includes an L-shaped sliding plate 221 slidably connected to the inner wall of the sliding groove 214;

[0074] Among them, the L-shaped sliding plates 221 are stacked together with multiple identical plates and are slidably connected to each other. The L-shaped sliding plates 221 can be extended and completely block the inner wall of the sliding groove 214.

[0075] The clamping mechanism 3 includes:

[0076] The clamping component 31 is fixedly installed at the bottom of the fan blade frame 213 through a limiting member;

[0077] The limiting member includes two slide rails 311 fixedly connected to the bottom of the fan blade frame 213. A slide rod 312 is slidably connected to the inner walls of the two slide rails 311;

[0078] The pressure-receiving component 32 is fixedly arranged at the inner wall of the sliding groove 214 through a pressure-receiving member;

[0079] A fixing rod 323 is fixedly connected between the two slide rods 312. A T-shaped sliding plate 322 is fixedly connected to the top of the fixing rod 323;

[0080] Among them, when the L-shaped sliding plate 221 extends outwards, it will drive the pressure-receiving component 32 to operate synchronously. At this time, the pressure-receiving component 32 will clamp and limit the bottom of the drive disk 211 through the clamping component 31.

[0081] Example 2. Please refer to Figure 3 - Figure 10 In this invention, an energy-saving cooling tower water turbine is provided. On the basis of Example 1, the driving assembly 11 includes a pressure-receiving fan blade 112 fixedly connected to one end of the driving rod 111 away from the driving disk 211. The outer wall of the pressure-receiving fan blade 112 is slidably connected to the inner wall of the housing 13. A rotational speed sensor 123 is fixedly arranged at the inner wall of the housing 13, and the inner wall of the rotational speed sensor 123 is rotatably connected to the outer wall of the driving rod 111. When cooling is required, an external water source is transmitted into the housing 13 through the water inlet pipe 121. At this time, the impact force generated by the high-pressure water body will act on the outer wall of the pressure-receiving fan blade 112, causing the pressure-receiving fan blade 112 to drive the driving rod 111 and the driving disk 211 to rotate.

[0082] Among them, the external water body impacts the pressure-receiving fan blade 112, causing the pressure-receiving fan blade 112 to drive the driving rod 111 to rotate.

[0083] The circulation assembly 12 includes a water inlet pipe 121 penetrating and connected to the side wall of the housing 13, and a water outlet pipe 122 penetrating and connected to the side wall of the housing 13;

[0084] Among them, the external water body is transmitted into the housing 13 through the water inlet pipe 121, and then discharged outwards from the water outlet pipe 122.

[0085] The fan blade assembly 21 includes a fixed block 215 fixedly connected to one end of the fan blade frame 213 away from the driving disk 211;

[0086] Among them, when the L-shaped sliding plate 221 extends outwards, the corresponding L-shaped sliding plate 221 will move towards the direction of the fixed block 215 to complete the filling of the sliding groove 214;

[0087] The shielding assembly 22 includes a first spring 222 fixedly connected inside the L-shaped sliding plate 221. One end of the L-shaped sliding plate 221 away from the clamping frame 212 is fixedly connected with a counterweight 223, and the outer wall of the counterweight 223 is slidably connected to the inner wall of the sliding groove 214;

[0088] Among them, when the fan blade frame 213 rotates, the centrifugal force will force the counterweight 223 to slide outwards along the inner wall of the sliding groove 214 and drive the L-shaped sliding plate 221 to slide outwards;

[0089] Due to the characteristic that the counterweight 223 moves outwards under the influence of the centrifugal force, after the counterweight 223 moves outwards, the counterweight components of the fan blade frame 213 are dispersed to the overall outer peripheral part. At this time, the potential energy generated by the rotation of the counterweight 223 increases, and this potential energy will be converted into the thrust for the rotation of the fan blade frame 213, so that while the fan blade frame 213 is subject to the thrust of the high-pressure water body, the potential energy generated by the counterweight 223 will offset part of the resistance generated by the rotation, ensuring the rotation speed and efficiency of the fan blade frame 213.

[0090] The clamping assembly 31 includes a fixing frame 313 fixedly connected to the bottom of the slide rail 311. A rack 314 is fixedly connected to the top of the fixing frame 313. A cylinder 315 is rotatably connected to the inner wall of the slide rod 312. A torsion spring 316 is sleeved on the outer wall of the cylinder 315. One end of the torsion spring 316 away from the cylinder 315 is fixedly connected to a lever 317. The side wall of the lever 317 is rotatably connected to the side wall of the slide rod 312. One end of the cylinder 315 away from the slide rod 312 is fixedly connected to a first gear 318. The driving disk 211 rotates synchronously through the fan blade frame 213. The centrifugal force generated by the rotation will force the counterweight 223 to slide outward along the inner wall of the sliding groove 214, so that the counterweight 223 can drive the L-shaped slide plate 221 to extend outward;

[0091] Among them, when the counterweight 223 moves outward, the side wall of the T-shaped slide plate 322 will contact the side wall of the T-shaped slide plate 322. The T-shaped slide plate 322 drives the slide rod 312 to slide through the fixing rod 323;

[0092] As the internal impact force increases, the rotation speed of the fan blade frame 213 continuously increases. At this time, the thrust generated by the outward sliding of the counterweight 223 also increases accordingly. When the L-shaped slide plate 221 completely covers the inner wall of the sliding groove 214, the side wall of the counterweight 223 also contacts the side wall of the T-shaped slide plate 322. When the thrust generated by the counterweight 223 increases, at this time the thrust will force the T-shaped slide plate 322 to move outward along the inner wall of the sliding groove 321. The outward moving T-shaped slide plate 322 drives the slide rod 312 to move along the inner wall of the slide rail 311 in the direction of the second spring 324 through the fixing rod 323. The slide rod 312 will drive a plurality of cylinders 315 to move outward synchronously. In this process, the first gear 318 will roll along the outer wall of the rack 314. The rolling first gear 318 will drive the cylinder 315 to rotate counterclockwise. The cylinder 315 drives the lever 317 to rotate upward synchronously through the torsion spring 316, so that one end of the lever 317 contacts the bottom of the L-shaped slide plate 221, so that the lever 317 changes from the state of Figure 8 to the state of G in Figure 9 Through the application of the above components, when the rotation speed of the fan blade frame 213 increases, at this time the lever 317 will clamp and limit the bottom of the L-shaped slide plate 221, greatly reducing the vibration frequency generated when the L-shaped slide plate 221 rotates.

[0093] The pressure - receiving component 32 includes a sliding groove 321 formed in the inner wall of the fixed block 215. The outer wall of the T - shaped sliding plate 322 is slidably connected to the inner wall of the sliding groove 321. A second spring 324 is fixedly connected to the side wall of the T - shaped sliding plate 322, and the end of the second spring 324 away from the T - shaped sliding plate 322 is fixedly connected to the inner wall of the sliding groove 321. In the early stage of equipment use, the L - shaped sliding plate 221 will be stacked near the center of the equipment. At this time, the counterweights of the equipment are mostly concentrated around the driving disc 211. Among them, the closer the counterweight is to the center position, the less power is required for its movement, and the farther the counterweight is from the center position, the greater the power required for its movement. Therefore, the L - shaped sliding plate 221 and the counterweight block 223 are mostly stacked around the driving disc 211, greatly reducing the power required for the equipment to start in the early stage, and avoiding excessive thrust on the internally pressured fan blade 112 due to pushing the fan blade to rotate, resulting in deformation of the fan blade.

[0094] Among them, after the rotational speed drops, as the centrifugal force drops, the second spring 324 will push the T - shaped sliding plate 322 to slide outward along the inner wall of the sliding groove 321.

[0095] The design of the torsion spring 316 enables, after part of the prying lever 317 contacts the bottom of the L - shaped sliding plate 221, as the sliding rod 312 moves horizontally, at this time, the first gear 318 will continue to rotate, and the torsional force generated by the rotation will be absorbed by the torsion spring 316. The torsion spring 316 will generate an upward - pushing force, forcing the other end of the prying lever 317 to press more closely against the bottom of the L - shaped sliding plate 221. The above design enables different prying levers 317 to adapt to L - shaped sliding plates 221 with different heights.

[0096] The control system of this energy - saving cooling tower water turbine includes the following steps:

[0097] S1: Rotational speed detection: The rotational speed of the pressured fan blade 112 is detected by a rotational speed sensor 123 installed on the inner wall of the housing 13. When the rotational speed of the driving rod 111 is too slow or too fast, an electrical signal will be sent to the operation platform.

[0098] S2: Human - machine interaction: For the convenience of maintenance and operation, the staff needs to monitor the data of the operation platform in real - time, view the system parameters through the background, and receive fault alarm information.

[0099] A specific application of this embodiment is as follows: Before use, first fix the housing 13 at the required position, then fixedly install multiple fan blade assemblies 21 on the top of the driving disc 211 through the clamping frame 212. Subsequently, ensure that the water inlet pipe 121 is connected to the water inlet, and the water outlet pipe is connected to the water outlet pipe 122 to complete the preliminary preparation process of the equipment.

[0100] When cooling is required, an external water source is transmitted through the water inlet pipe 121 to the inside of the housing 13. At this time, the impact force generated by the high-pressure water body will act on the outer wall of the housing 13, causing the housing 13 to drive the drive rod 111 and the drive disk 211 to rotate. The drive disk 211 rotates synchronously through the fan blade holder 213, and the centrifugal force generated by the rotation will force the counterweight 223 to slide outward along the inner wall of the sliding groove 214, enabling the counterweight 223 to drive the L-shaped sliding plate 221 to extend outward. Eventually, the outward-extended L-shaped sliding plate 221 will completely cover the inside of the sliding groove 214, causing the L-shaped sliding plate 221 to change from Figure 1 the state of Figure 2 to the state of

[0101] . Through the application of the above components, in the early stage of equipment use, the L-shaped sliding plate 221 will be stacked near the center of the equipment. At this time, the counterweight of the equipment is mostly concentrated around the drive disk 211. Among them, the closer the counterweight is to the center position, the less power is required for its movement, and the farther the counterweight is from the center position, the greater the power required for its movement. Therefore, the L-shaped sliding plate 221 and the counterweight 223 are mostly stacked around the drive disk 211, greatly reducing the power required for the equipment to start in the early stage and avoiding excessive deformation of the internal compressed fan blade 112 due to the large thrust required to drive the fan blade to rotate; Among them, as the internal impact force increases, the rotation speed of the fan blade holder 213 continues to increase. At this time, the thrust generated by the outward sliding of the counterweight 223 also increases accordingly. When the L-shaped sliding plate 221 completely covers the inner wall of the sliding groove 214, the side wall of the counterweight 223 also contacts the side wall of the T-shaped sliding plate 322. When the thrust generated by the counterweight 223 increases, this thrust will force the T-shaped sliding plate 322 to move outward along the inner wall of the sliding groove 321. The outward-moved T-shaped sliding plate 322 drives the sliding rod 312 to move along the inner wall of the slide rail 311 in the direction of the spring two 324 through the fixed rod 323. The sliding rod 312 will drive a number of cylinders 315 to move outward synchronously. During this process, the first gear 318 will roll along the outer wall of the toothed rod 314. The rolling first gear 318 will drive the cylinder 315 to rotate counterclockwise. The cylinder 315 drives the prying lever 317 to rotate upward synchronously through the torsion spring 316, causing one end of the prying lever 317 to contact the bottom of the L-shaped sliding plate 221, causing the prying lever 317 to change from Figure 8 the state of Figure 9 to the state of G in

[0102] . Through the application of the above components, when the rotation speed of the fan blade holder 213 increases, the prying lever 317 will clamp and limit the bottom of the L-shaped sliding plate 221, greatly reducing the vibration frequency generated by the L-shaped sliding plate 221 during rotation.Among them, the fan blade holder 213 is set to a hollow state, effectively avoiding excessive contact area between the rotation of the fan blade holder 213 and the external air during the initial startup, which may lead to an increase in the power required for the initial startup of the fan blade holder 213. In addition, the design of the torsion spring 316 enables, after a part of the pry bar 317 contacts the bottom of the L-shaped sliding plate 221, as the sliding rod 312 moves horizontally, at this time the first gear 318 will continue to rotate, and the torsional force generated by the rotation will be absorbed by the torsion spring 316. The torsion spring 316 will generate an upward pushing force, forcing the other end of the pry bar 317 to press more closely against the bottom of the L-shaped sliding plate 221. The above design enables different pry bars 317 to adapt to L-shaped sliding plates 221 with different heights.

[0103] Utilizing the characteristic that the counterweight 223 moves outward under the influence of centrifugal force, after the counterweight 223 moves outward, at this time the counterweight components of the fan blade holder 213 are dispersed to the overall outer peripheral part. At this time, the potential energy generated by the rotation of the counterweight 223 increases, and this potential energy will be converted into the thrust for the rotation of the fan blade holder 213. When the fan blade holder 213 is subjected to the thrust of the high-pressure water body, the potential energy generated by the counterweight 223 will offset part of the resistance generated by the rotation, ensuring the rotation speed and efficiency of the fan blade holder 213.
