Description

A photovoltaic-based windbreak irrigation device Technical Field

[0001] This invention relates to the field of irrigation technology, and more specifically to a photovoltaic-based windbreak irrigation device. Background Technology

[0002] In areas with strong winds and scarce water resources, such as deserts, rocky desertification areas, and salinized areas, the soil is infertile and extremely lacking in fresh water. Plant seeds cannot attach and grow in loose substrates such as shifting sand, and the long growth cycle and low survival rate of plants result in slow progress in plant-based sand control and soil stabilization, as well as ecological restoration. Photovoltaic power generation systems refer to power generation systems that directly convert solar radiation energy into electrical energy using the photovoltaic effect of photovoltaic cells. Originating from inexhaustible solar energy, it is a clean, safe, and renewable energy source. Therefore, combining photovoltaic power generation with desertification control can achieve a win-win situation of ecological restoration and clean energy development through photovoltaic technology.

[0003] These areas typically feature vast open spaces, low rainfall, and long hours of sunshine, making them ideal for photovoltaic (PV) power generation systems. The energy generated by PV can also aid in desertification control and vegetation irrigation. However, these areas are often far from urban areas and face difficulties in accessing electricity. Therefore, utilizing solar energy resources and converting it into mechanical energy to drive irrigation systems is of great significance for agricultural development and ecological restoration in these regions. However, irrigation in such areas, especially in desert regions, is hampered by strong winds that cause water loss during sprinkler irrigation, preventing the water from accurately reaching the target area. Therefore, an irrigation device suitable for these windy and water-scarce regions is needed. Summary of the Invention

[0004] In view of this, the present invention provides a photovoltaic-based wind-resistant irrigation device that can adjust the nozzle outlet flow rate to reduce the impact of wind on irrigation.

[0005] The technical solution adopted in this invention is as follows:

[0006] A photovoltaic-based windbreak irrigation device includes a support body, photovoltaic panels, mounting frame, irrigation pipe, sprinkler head, annular protective cover, and auxiliary mechanisms.

[0007] A photovoltaic panel is provided on the upper surface of the main body of the support frame, and an installation frame is provided on one side of the main body of the support frame.

[0014] Both ends of the sliding plate are slidably engaged with corresponding sliding grooves and sliding holes via sliding rods to control the flow rate at the nozzle outlet; the sliding rods at both ends are coaxial and are an integral structure with the sliding plate.

[0015] Furthermore, the sliding plate includes abutment surface I and abutment surface II, which form an acute angle, and adjacent sliding plates are fitted together through abutment surface I and abutment surface II.

[0016] Furthermore, the irrigation device also includes an adjustment mechanism for extending the protective height and an expansion mechanism;

[0017] The adjustment mechanism includes a contact member, a movable member, and an adjusting member; several contact members are disposed at the bottom end of the annular member; one end of the movable member is connected to the adjusting member, and the other end extends out from the outer circumferential surface of the annular cover, and the upper end of the movable member has a slot for the contact member to pass through; the adjusting member is disposed inside the annular cover; when the contact member rotates with the annular member, the movable member reciprocates linearly, causing the adjusting member to expand or contract, and the adjusting member extends out from the annular cover after expansion;

[0018] The expansion mechanism includes a movable component disposed on the inner wall of the annular cover and an auxiliary component disposed at the bottom end of the annular component. The movable component and the auxiliary component cooperate to fill the gap of the adjacent adjusting component extending out of the annular cover, and at the same time fill the gap between the annular cover and the adjusting component.

[0019] Furthermore, the abutting member includes a connecting rod arranged circumferentially at the bottom end of the annular plate, and an annular edge arranged at the bottom end of multiple sets of the connecting rods;

[0020] A variable diameter section is provided on the outer wall of the annular edge along the circumferential direction. The variable diameter section is composed of arc-shaped surface I and arc-shaped surface II.

[0021] Furthermore, the movable component includes a movable plate and a bearing II;

[0022] One end of the movable plate is rotatably connected to the bearing seat II, the bearing seat II is mounted on the adjusting member, and the other end of the movable plate extends out from the annular protective cover; a locking block is integrally formed on one end of the slot on the movable plate, and the locking block is correspondingly located above the variable diameter part; the movable plate is slidably connected to the movable opening provided on the bottom end face of the annular protective cover.

[0023] Furthermore, the adjusting component includes an adjusting plate, a bearing seat I, and a compression spring;

[0025] Furthermore, the moving component includes a tension spring and a moving plate;

[0026] The inner wall of the annular cover is provided with a mounting groove, which is distributed along the circumference; one end of the tension spring is fixed to the top of the inner wall of the mounting groove, and the other end is provided with a movable plate, the upper surface of which is formed with a wedge-shaped part.

[0027] Furthermore, the auxiliary component includes an auxiliary block disposed on the annular component and an abutting portion disposed at the bottom end of the auxiliary block, the abutting portion correspondingly engaging with the wedge-shaped portion. Beneficial effects

[0028] 1. This invention, by incorporating an auxiliary mechanism within the annular protective cover to adjust the flow rate at the nozzle outlet, allows for control of the internal flow rate of the annular cover. This reduces the opening size during strong winds, resulting in more concentrated irrigation and minimizing the impact of wind on irrigation. Simultaneously, the annular cover effectively blocks wind and sand intrusion, preventing damage to the internal components and ensuring the device's durability, making it less prone to malfunctions due to wind and sand.

[0029] 2. The auxiliary mechanism of the present invention drives the ring to rotate through the driving component, so that the offset component is offset to block the nozzle outlet, thereby adjusting the flow rate. The force transmission method and structure are simple and easy to implement.

[0030] 3. The sliding plate of the offset component of the present invention moves along with the rotation of the annular component, thereby blocking the nozzle outlet. The structure is compact and the linkage mechanism is simple and reliable.

[0031] 4. The present invention also includes an adjustment mechanism for extending the protective height, which further improves the wind-blocking effect of the annular cover during use. Since the internal protection of the adjustment component creates a certain gap during use, the present invention fills the gap by providing an expansion mechanism inside the annular cover, thereby further avoiding the impact of wind on irrigation.

[0032] 5. The present invention is equipped with an adjustment mechanism, which causes the annular plate to rotate while driving the variable diameter part to rotate. The variable diameter part is composed of arc-shaped surface I and arc-shaped surface II. Arc-shaped surface I is in contact with the inside of the locking block. When arc-shaped surface I is in contact with the inside of the locking block, the radius gradually increases, thereby driving the movable plate to slide within the movable opening. At this time, the movable plate is rotatably connected to the adjustment plate through the bearing II, and the adjustment plate is rotatably connected to the inner wall of the annular cover through the bearing I. At this time, the adjustment plate is in an expanded state, extending the protective height and enhancing the windproof effect.

[0033] 6. The present invention is provided with an expansion mechanism, which causes the annular plate to rotate while driving the annular strip on the connecting block to rotate. At this time, the annular strip drives the contact part on the auxiliary block to rotate simultaneously. When it rotates, the contact part contacts the wedge-shaped part, thereby squeezing the moving plate and causing the moving plate to move in the vertical direction. At the same time, the tension spring deforms. When the moving plate moves downward, it fills the gap after the adjusting plate rotates around the shaft seat I, further avoiding the impact of wind on irrigation. Attached Figure Description

Detailed Implementation

[0046] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0047] The present invention provides a photovoltaic-based windproof irrigation device, including a support body 100, a photovoltaic panel 101, a mounting frame 102, an irrigation pipe 103, a nozzle 105, an annular protective cover 106, and an auxiliary mechanism 200.

[0048] As shown in Figures 1 and 2, a photovoltaic panel 101 is mounted on the upper surface of the support body 100. A mounting frame 102 is mounted on one side of the support body 100, and an irrigation pipe 103 is mounted on the mounting frame 102. Multiple sets of nozzles 105 are mounted on the irrigation pipe 103, and the nozzles 105 are mounted on the irrigation pipe 103 via a spray base 104. An annular protective cover 106 is provided at the bottom of the nozzle 105, and an auxiliary mechanism 200 for adjusting the outlet flow of the nozzle 105 is provided inside the annular protective cover 106.

[0049] In this embodiment, the annular protective cover 106 has an opening 107 in the middle, and the opening 107 is connected to the outlet of the nozzle 105, that is, the nozzle 105 is located inside the opening 107. In other words, the auxiliary mechanism 200 directly adjusts the outlet flow rate of the opening 107.

[0050] Taking the application of this device in desert areas as an example, photovoltaic desertification control is an innovative model that combines photovoltaic power generation with desert management. It mainly achieves a win-win situation of ecological restoration and clean energy development through photovoltaic technology. The installation of photovoltaic panels 101 can effectively reduce surface wind speed and wind erosion, thereby stabilizing the sand and preventing sand dune movement. In addition, the shading effect of photovoltaic panels 101 can reduce surface water evaporation. At the same time, photovoltaic panels 101 can regulate the thermal balance of desert areas, weaken the power of sandstorms and sand flows, and its rainwater collection effect can also promote plant growth.

[0051] The "Photovoltaic + Desertification Control" model involves planting drought-resistant plants, such as sand rice, sand wormwood, and alfalfa, under and between photovoltaic panels 101. This not only helps prevent wind erosion and sand fixation but also brings economic benefits. The space under and between photovoltaic panels 101 is used for planting and breeding, developing water-saving agriculture and forming a comprehensive model of above-ground power generation, ground planting, and breeding between panels. Furthermore, ecotourism is developed around the photovoltaic power station, combined with the construction of protective forest belts and industrial parks, to achieve a combination of ecological and economic benefits.

[0052] Photovoltaic desertification control can significantly increase vegetation coverage, increase soil moisture, and reduce the frequency of sandstorms. For example, after the photovoltaic power station is built, the vegetation coverage can reach more than 80%, which is 40% higher than outside the park. The yield of fresh grass is four times that outside the park. At the same time, photovoltaic desertification control projects can generate a large amount of green electricity, while driving the development of related industries and creating employment opportunities. Therefore, photovoltaic desertification control has brought significant economic benefits to the local community and promoted rural revitalization and ecotourism development.

[0053] The "photovoltaic + agriculture" model converts sunlight into electricity through photovoltaic panels 101. When sunlight shines on the photovoltaic panels 101, photons are absorbed and electrons are excited, generating direct current (DC). This DC is transmitted through cables to an inverter, which converts it into alternating current (AC) to meet the power needs of the water pump. The converted electricity drives the water pump, which draws water from groundwater, rivers, or lakes and delivers it to the irrigation pipe 103 via pipelines. The pump's power, flow rate, and head need to be matched to the irrigation requirements, and different irrigation methods, such as sprinkler and drip irrigation, can be selected based on actual needs. In severely water-scarce desert areas, a rainwater harvesting system can be added. This system includes a collection module and a storage module. The collection module uses a trough structure to collect rainwater, while the storage module, connected to the collection module, stores the collected rainwater.

[0054] Desert regions are vast, receive little rainfall, and have long hours of sunshine, making them ideal for photovoltaic power generation systems. They also contribute to desertification control and vegetation irrigation. Furthermore, desert regions are generally far from urban areas. However, strong winds in desert regions can lead to water loss during sprinkler irrigation, mainly because water droplets are scattered in the air and cannot accurately reach the target area.

[0055] Existing technology uses a protective cover at the bottom of the sprinkler head 105 to block wind and reduce the impact of wind on irrigation. This invention further improves the structure of the protective cover by providing an auxiliary mechanism 200 inside the annular protective cover 106. The auxiliary mechanism 200 changes the size of the opening 107 in the middle of the annular protective cover 106, thereby controlling the internal flow of the annular protective cover 106. In strong winds, reducing the opening 107, according to Bernoulli's principle, makes the irrigation more concentrated, thus reducing the impact of wind on irrigation.

[0056] Specifically, the auxiliary mechanism 200 includes a driving component 201, an annular component 202, and an offset component 203. The driving component 201 is disposed on the upper end face of the annular cover 106, the annular component 202 is fitted outside the annular cover 106, and the offset component 203 is disposed inside the annular component 202, and the offset component 203 is located inside the annular cover 106 at the outlet of the nozzle 105. The driving component 201 drives the annular component 202 to rotate, so that the offset component 203 adjusts the outlet flow of the nozzle 105.

[0057] As shown in Figure 3, the driving component 201 includes a fixed frame 201a, a motor 201b, and a gear 201c, which are fixedly connected to the upper end face of the annular cover 106. The motor 201b is detachably mounted on the upper end of the fixed frame 201a, and the gear 201c is connected to one end of the rotor shaft of the motor 201b that passes through the fixed frame 201a.

[0058] The upper end of the annular component 202 is an annular plate 202b, and a gear ring 202c is fixedly connected to the inner wall of the annular plate 202b. The gear ring 202c meshes with the gear 201c.

[0059] The mounting bracket 201a has a U-shaped structure to ensure the stability of the device during use. The motor 201b is bolted to the mounting bracket 201a. The output shaft of the motor 201b is keyed to a gear 201c. The gear 201c meshes with the gear ring 202c on the inner wall of the annular plate 202b, thereby driving the annular plate 202b on the inner ring to rotate. The rotation direction and angle of the rotor shaft of the motor 201b are adjusted by an external controller. When the wind speed exceeds level 4, the external controller sends a command to adjust the operation of the motor 201b, thereby rotating the gear 201c on the rotor shaft of the motor 201b. Since the gear 201c meshes with the gear ring 202c, it drives the annular plate 202b outside the gear ring 202c to rotate.

[0060] A protective space 202d is formed inside the annular cover 106, and symmetrical annular holes 202a are provided on the upper end surface of the annular cover 106. A connecting block 202e is fixedly connected to the bottom end of the annular plate 202b. The connecting block 202e is slidably engaged with the annular hole 202a. An annular strip 202f is provided at one end of the connecting block 202e that passes through the annular hole 202a on the upper end surface of the annular cover 106. A circular plate 202h is fixedly connected between multiple sets of connecting plates 202g. A hollow hole 202i is provided in the middle position of the circular plate 202h. The hollow hole 202i is connected to the opening 107.

[0061] The protective space 202d formed inside the annular shield 106 blocks the wind, thereby reducing the impact of wind on irrigation. The bottom end of the annular plate 202b is symmetrically and fixedly connected to a long strip-shaped connecting block 202e. The connecting block 202e is correspondingly slidably connected in the annular hole 202a. The bottom end of the connecting block 202e is fixedly connected to an annular strip 202f. Therefore, when the annular plate 202b rotates, it drives the annular strip 202f on the connecting block 202e to rotate. Six sets of connecting plates 202g are fixedly connected in a circular pattern on the outer wall of the annular strip 202f. A circular plate 202h is fixedly connected between the six sets of connecting plates 202g. As can be seen from the above, the annular strip 202f drives the circular plate 202h inside the connecting plate 202g to rotate.

[0062] The offset component 203 includes a sliding plate 203b, a sliding rod, and a connecting plate 202g; the connecting plate 202g is horizontally evenly distributed on the annular strip 202f, and the connecting plate 202g is provided with sliding holes 203e; the inner top surface of the annular cover 106 is provided with a sliding groove 203a, which is circumferentially opened, and two adjacent sets of sliding grooves 203a are symmetrically arranged and intersect each other, and the angle between two adjacent sets of sliding grooves 203a is an obtuse angle; both ends of the sliding plate 203b are slidably engaged with the corresponding sliding grooves 203a and sliding holes 203e through sliding rods to control the size of the outlet flow of the nozzle 105; the sliding rods at both ends are coaxial and are an integral structure with the sliding plate 203b.

[0063] More specifically, as shown in Figure 4, the sliding plate 203b includes abutment surface I 203c and abutment surface II 203d, which form an acute angle. Adjacent sliding plates 203b are fitted together through abutment surface I 203c and abutment surface II 203d. There are six sliding plates 203b.

[0064] As shown in Figure 5, the inner wall of the annular cover 106 is provided with six sets of elongated grooves 203a in a circular shape. The two sets of grooves 203a intersect each other. Each groove 203a is slidably connected to a corresponding sliding plate 203b, and the sliding plate 203b only slides in its corresponding groove 203a.

[0065] The photovoltaic power generation system mainly consists of photovoltaic modules, a controller, an inverter, and a battery. The specific working process is as follows: When sunlight shines on the photovoltaic modules, the photovoltaic cells absorb light energy and generate direct current (DC). The generated DC is transmitted to the controller through wires. The controller manages and regulates the DC, and then transmits it to the inverter. The inverter converts the DC into alternating current (AC). The converted AC is then transmitted to the motor 201b through a cable to provide power to the motor 201b. When there is sufficient sunlight, excess electrical energy is stored in the battery through the controller. When there is insufficient sunlight or at night, the battery supplies power to the motor 201b through the inverter.

[0066] Working principle: As shown in Example 1, when the wind sensor detects that the wind force exceeds level 4, the operator sends a command through an external controller to adjust the motor 201b for operation. This causes the gear 201c at the rotor shaft end of the motor 201b to rotate. Since the gear 201c meshes with the gear ring 202c, it drives the annular plate 202b outside the gear ring 202c to rotate. When the annular plate 202b rotates, it drives the annular strip 202f on the connecting block 202e to rotate. When the annular strip 202f rotates, it drives the circular plate 202h on its connecting plate 202g to rotate synchronously. The moving rod 203f rotates within the sliding hole 203e and the sliding groove 203a. Due to the offset of the sliding hole 203e, the sliding plate 203b on the sliding rod 203f moves within the sliding groove 203a, and adjacent sliding plates 203b are in contact with each other through the contact surface I 203c and the contact surface II 203d. In this way, the size of the opening 107 inside the annular cover 106 is adjusted, thereby controlling the internal flow of the annular cover 106. Thus, in the case of strong winds, the opening 107 is reduced, and the reduction of the opening 107 makes the sprinkler irrigation more concentrated, thereby reducing the impact of wind on irrigation. Example

[0067] Based on Embodiment 1, the irrigation device of the present invention further includes an adjustment mechanism 300 for extending the protective height and an expansion mechanism.

[0068] The adjustment mechanism 300 includes a contact member 301, a movable member 302, and an adjustment member 303. As shown in Figure 6, several contact members 301 are disposed at the bottom end of the annular member 202. One end of the movable member 302 is connected to the adjustment member 303, and the other end extends out from the outer circumferential surface of the annular cover 106. A slot 302c is provided on the upper end of the movable member 302 for the contact members 301 to pass through. The adjustment member 303 is disposed inside the annular cover 106. When the contact member 301 rotates with the annular member 202, the movable member 302 reciprocates linearly, causing the adjustment member 303 to expand or contract. After expansion, the adjustment member 303 extends out from the annular cover 106.

[0069] The expansion mechanism 400 includes a movable part 401 disposed on the inner wall of the annular cover 106 and an auxiliary part 402 disposed at the bottom of the annular part 202. The movable part 401 and the auxiliary part 402 cooperate to fill the gap of the adjacent adjusting part 303 extending out of the annular cover 106, and at the same time fill the gap between the annular cover 106 and the adjusting part 303, further avoiding the impact of wind on irrigation.

[0070] Specifically, the abutting member 301 includes a connecting rod 301a arranged circumferentially at the bottom end of the annular plate 202b, and an annular edge 301b arranged at the bottom end of multiple sets of connecting rods 301a; a variable diameter part 301c is provided on the outer wall of the annular edge 301b along the circumferential direction, and the variable diameter part 301c is composed of arc-shaped surface I 301d and arc-shaped surface II 301e.

[0071] As shown in Figures 7 and 9, eight sets of elongated connecting rods 301a are fixedly connected to the bottom of the annular plate 202b in a circular shape. Annular edges 301b are fixedly connected to the bottom of the eight sets of connecting rods 301a. The annular edges 301b are attached to the outer side of the annular cover 106. As can be seen from Embodiment 1, when the annular plate 202b rotates, it drives the annular edges 301b on the connecting rods 301a to rotate. The annular edges 301b drive the variable diameter part 301c to rotate synchronously.

[0072] As shown in Figure 8, the movable component 302 includes a movable plate 302b and a bearing seat II 303c; one end of the movable plate 302b is rotatably connected to the bearing seat II 303c, the bearing seat II 303c is mounted on the adjusting component 303, and the other end of the movable plate 302b extends out from the annular cover 106; a locking block 302d is integrally formed at one end of the slot 302c on the movable plate 302b, and the locking block 302d is correspondingly located above the variable diameter part 301c; the movable plate 302b is slidably connected to the movable opening 302a provided on the bottom end surface of the annular cover 106.

[0073] The adjusting component 303 includes an adjusting plate 303b, a bearing seat I 303a, and a compression spring 303d. The upper end of the adjusting plate 303b is rotatably connected to the annular cover 106 via the bearing seat I 303a. The lower inner wall of the adjusting plate 303b is symmetrically provided with compression springs 303d. The compression springs 303d are carbon springs, which are high in strength and convenient for daily use. Multiple sets of compression springs 303d are correspondingly arranged on the inner wall of the annular cover 106. The lower end of the adjusting plate 303b is fixedly connected to the bearing seat II 303c.

[0074] As shown in Figure 3, the bottom of the annular cover 106 has eight sets of movable openings 302a in a circular shape. The movable openings 302a are square-shaped, and a movable plate 302b is slidably connected inside the movable openings 302a. One side of the movable plate 302b is rotatably connected to the adjusting plate 303b through a bearing II 303c. The adjusting plate 303b is connected to the inner wall of the annular cover 106 through two sets of compression springs 303d. The outer wall of the movable plate 302b is provided with a slot 302c, and a locking block 302d is integrally formed on the side wall of the slot 302c. Correspondingly, above the variable diameter section 301c, the variable diameter section 301c abuts against the inner side of the locking block 302d. When the annular edge 301b rotates, the variable diameter section 301c presses the movable plate 302b, causing the movable plate 302b to slide over the arc surface I 301d and the arc surface II 301e, thereby causing the movable plate 302b to reciprocate radially along the annular cover 106. Since the movable plate 302b is rotatably connected to the adjusting plate 303b, the adjusting plate 303b expands or contracts. At the same time, the compression spring 303d deforms.

[0075] Working principle: When the annular plate 202b rotates, the annular edge 301b at the bottom of the connecting rod 301a rotates as well. The annular edge 301b drives the variable diameter part 301c to rotate. The arc-shaped surface I 301d of the variable diameter part 301c contacts the inside of the locking block 302d. When the arc-shaped surface I 301d contacts the inside of the locking block 302d, the radius gradually expands, thereby driving the movable plate 302b to slide within the movable opening 302a. At this time, the movable plate 302b is rotatably connected to the adjusting plate 303b through the bearing II 303c. The adjusting plate 303b is rotatably connected to the inner wall of the annular cover 106 through the bearing I 303a. At this time, the adjusting plate 303b is in an expanded state, that is, it extends from the bottom of the annular cover 106, extending the protective height. At the same time, the compression spring 303d deforms. When the adjusting plate 303b expands, the windproof effect is enhanced.

[0076] When the motor 201b drives the gear 201c to rotate, the gear 201c meshes with the gear ring 202c, and the gear ring 202c drives its outer annular plate 202b to rotate. The arc-shaped surface I 301d contacts the inside of the locking block 302d. As its radius gradually decreases, the restoring force driven by the compression spring 303d causes the adjusting plate 303b to rotate, thereby causing the adjusting plate 303b to retract to the inside of the annular cover 106.

[0077] In summary, in its initial state, the annular cover 106 and the adjusting plate 303b of this device block the wind. When the wind increases, the size of the opening 107 of the annular cover 106 is adjusted by the auxiliary mechanism 200, and the adjusting plate 303b expands to increase the windproof space, thereby reducing the impact of wind on irrigation.

[0078] Further, as shown in Figures 10 and 11, the movable component 401 includes a tension spring 401b and a movable plate 401c; the inner wall of the annular cover 106 is provided with a mounting groove 401a, which is distributed along its circumference; the tension spring 401b is a carbon spring with high strength, which is convenient for daily use; one end of the tension spring 401b is fixed to the top of the inner wall of the mounting groove 401a, and the other end is provided with a movable plate 401c; a wedge-shaped portion 401d is formed on the upper surface of the movable plate 401c.

[0079] The auxiliary component 402 includes an auxiliary block 402a disposed on the annular component 202 and an abutting portion 402b disposed at the bottom end of the auxiliary block 402a, the abutting portion 402b correspondingly engaging with the wedge-shaped portion 401d.

[0080] The inner side of the annular cover 106 is symmetrically provided with eight sets of mounting slots 401a. A movable plate 401c is fixedly connected to the mounting slot 401a by a tension spring 401b. The movable plate 401c extends downward by moving vertically within the mounting slot 401a, so that the movable plate 401c fills the gap between adjacent adjusting plates 303b extending out of the annular cover 106. In order to ensure the stability of the movable plate 401c in the vertical direction, a wedge-shaped part 401d is integrally formed at the upper end of the movable plate 401c. At the same time, an auxiliary block 402a and a contact part 402b are fixedly connected to the bottom of the annular bar 202f. When the annular bar 202f rotates, it drives the contact part 402b on the auxiliary block 402a to contact the wedge-shaped part 401d, thereby driving the movable plate 401c to move in the vertical direction.

[0081] Working principle: When the annular plate 202b rotates, it drives the annular strip 202f on the connecting block 202e to rotate. At this time, the annular strip 202f drives the contact part 402b on the auxiliary block 402a to rotate simultaneously. When it rotates, the contact part 402b contacts the wedge-shaped part 401d, thereby squeezing the moving plate 401c, causing the moving plate 401c to move vertically. At the same time, the tension spring 401b deforms. When the moving plate 401c moves downward, as shown in Figure 9, it fills the gap between the adjacent adjusting plates 303b extending from the annular cover 106. When the annular plate 202b rotates back, the contact part 402b no longer abuts against the wedge-shaped part 401d. Under the restoring force of the tension spring 401b, the moving plate 401c is driven to reset.

[0082] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
