[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale.

[0025] Example 1

[0026] Reference Figures 1 to 5The first embodiment of the present invention provides a floating interception assembly 100, comprising a floating interception buoy 101 and an operating cavity 102 disposed within the floating interception buoy 101. The floating interception buoy 101, placed at the water inlet of a hydropower station, can intercept floating objects carried by the current, preventing them from entering the station and ensuring the normal operation of the hydropower station. A connecting assembly 200 includes a serial hole 201 formed on the floating interception buoy 101. The serial hole 201 facilitates the connection of individual floating interception buoys 101 via ropes, forming a floating interception chain and improving the interception performance of floating objects. An adjusting assembly 400 includes an adjusting cylinder 401 disposed within the operating cavity 102. The bottom of the adjusting cylinder 401 is provided with an inlet and outlet 402 extending through the floating interception buoy 101, and a filter is disposed within the inlet and outlet 402. The inlet and outlet 402 facilitates the entry of water into the adjusting cylinder 401, and the filter can filter the water entering the adjusting cylinder 401, preventing impurities such as aquatic plants from entering the adjusting cylinder 401.

[0027] Furthermore, the adjustment component 400 also includes a piston plate 403 slidably installed in the inner cavity of the adjustment cylinder 401, and a vent hole 405 connected to the inner cavity of the adjustment cylinder 401 is opened on the piston plate 403, and a sealing plate 406 for sealing the vent hole 405 is provided on the piston plate 403. A sealing ring 404 is provided on the edge of the piston plate 403 to fit the inner wall of the adjustment cylinder 401, and a driving component 409 for controlling the movement of the piston plate 403 and the sealing plate 406 is provided in the operating cavity 102. In this embodiment, the weight of the flowing water in the regulating cylinder 401 is controlled to achieve the operation of increasing the stability of the intercepting float 101, which not only reduces the use cost of the device, but also does not need to worry about the corrosion of the medium, thereby ensuring the performance of the intercepting float in intercepting floating objects. In specific operation, the vent 405 can be blocked by the sealing plate 406. At this time, if the intercepting float 101 is in water, the inner cavity of the regulating cylinder 401 is isolated from the outside world. Under the action of air pressure, the flowing water will not enter the regulating cylinder 401. When it is necessary to increase the weight of the intercepting float 101, the sealing plate 406 is rotated to make the regulating cylinder 401 communicate with the outside world through the vent 405. Then, the flowing water can enter the regulating cylinder 401 along the inlet and outlet 402, thereby increasing the weight of the intercepting float 101. Figure 1 As shown, the outer surface of the buoy 101 is provided with scale lines. The staff can observe the draft depth of the buoy 101 by setting the scale lines. At the same time, under the premise of closing the vent 405, they can squeeze the piston plate 403 downward to squeeze the excess water out of the regulating cylinder 401, and then open the vent 405. After the piston plate 403 is reset, the vent 405 is blocked again to achieve the effect of adjusting the weight of the buoy 101.

[0028] Furthermore, the driving assembly 409 includes a driving sleeve 409a slidably installed in the inner cavity of the adjusting cylinder 401, and one end of the driving sleeve 409a passes through the floating cylinder 101, and the other end is transmission-connected to the piston plate 403 and the sealing plate 406. A guide block 409e is provided on the driving sleeve 409a, and a rotating ring groove 409f for sliding the guide block 409e is provided on the inner wall of the floating cylinder 101 and close to the driving sleeve 409a. A guide groove 409g for limiting the rotation of the guide block 409e is provided on the end of the rotating ring groove 409f away from the piston plate 403. A sliding ring 1 409b is provided on the outside of the driving sleeve 409a and away from the guide groove 409g, and a sliding ring 2 409c is provided above the sliding ring 1 409b, and a telescopic spring 409d is provided between the sliding ring 1 409b and the sliding ring 2 409c. Under normal conditions, the guide block 409e is in the guide groove 409g under the action of the telescopic spring 409d. At this time, under the restriction of the guide groove 409g, the guide block 409e will not rotate. When the vent hole 405 needs to be opened, the driving sleeve 409a can be rotated and pressed to make the guide block 409e slide from the guide groove 409g to the rotating ring groove 409f, and then the driving sleeve 409a can be rotated to make the blocking plate 406 disengage from the vent hole 405, so that the vent hole 405 can be unblocked and water can be filled in. When draining, when the vent hole 405 is blocked, Directly press the drive sleeve 409a to cause the piston plate 403 to move downward, and then rotate the drive sleeve 409a to make the air pressure inside and outside the regulating cylinder 401 consistent, remove the extrusion force of the drive sleeve 409a, and under the action of the telescopic spring 409d, the drive sleeve 409a will quickly return to the top of the rotating ring groove 409f. At this time, the drive sleeve 409a can be rotated to align the upper guide block 409e with the guide groove 409g. The telescopic spring 409d can send the guide block 409e into the guide groove 409g. At this time, the vent 405 is closed.

[0029] During use, the operation of controlling the quality of river water in the regulating cylinder 401 is completed through the cooperation of components such as the piston plate 403 and the vent hole 405, thereby increasing the stability of the floating cylinder 101. This method not only reduces the cost of using the device, but also does not have to worry about the medium being corroded, thereby ensuring the performance of the floating cylinder in intercepting floating objects.

[0030] Example 2

[0031] Reference Figures 2 to 5, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: an extension rod 409h is slidably installed inside the driving sleeve 409a, and one end of the extension rod 409h is rotatably connected to the piston plate 403, and the outside of the extension rod 409h is coaxially fixed with the rotating end of the sealing plate 406, and an extension gear 409i is provided in the inner cavity of the driving sleeve 409a, and the two sides of the extension gear 409i are respectively engaged with the arc-shaped teeth 409j fixed on the inner wall of the operating cavity 102 and the extension rack 409k fixed on the extension rod 409h. When the driving sleeve 409a moves downward, it will drive the extension rod 409h to move together. At this time, the extension gear 409i set on the driving sleeve 409a will rotate under the action of the arc-shaped teeth 409j. Since the extension gear 409i is engaged with the extension rack 409k set on the extension rod 409h, the extension rack 409k will accelerate the downward movement of the extension rod 409h, thereby extending the movement range of the piston plate 403 and increasing the discharge amount of the equipment to the river water inside the regulating cylinder 401.

[0032] Furthermore, a synchronous gear 1 407 is coaxially secured to the exterior of the extension rod 409h. Synchronous gear 1 407 is externally engaged with a synchronous gear 2 408, which meshes with the inner wall of the operating cavity 102. One end of synchronous gear 2 408 extends through the inner wall of the damming buoy 101. Because one end of synchronous gear 2 408 extends through the inner wall of the damming buoy 101, when two damming buoys 101 are connected, adjacent synchronous gears 2 408 mesh with each other. Rotating either drive sleeve 409a opens the vents 405 in the adjacent damming buoy 101, thereby reducing the workload and manpower required to control the water inflow.

[0033] Furthermore, a bend 103 is provided in the middle of the buoy 101. The buoy chain formed by the plurality of buoys 101 will not be straight under the impact of the water flow. The provision of the bend 103 will cause the buoys 101 to bend to varying degrees according to the direction of the water flow, thereby reducing the impact of the water flow and extending the service life of the buoys 101.

[0034] During use, the movement range of the piston plate 403 is extended by setting components such as the extension rod 409h and the extension gear 409i, thereby increasing the discharge volume of the river water inside the regulating cylinder 401, and utilizing the cooperation of the synchronous gear 1 407 and the synchronous gear 2 408 to reduce the workload of the staff in controlling the weight of the floating cylinder 101.

[0035] The remaining structures are the same as those of Example 1.

[0036] Example 3

[0037] Reference Figure 1 and Figure 5This is the third embodiment of the present invention. This embodiment differs from the second embodiment in that the connecting assembly 200 further includes a mounting slot 202 formed on the upper portion of the buoy 101, with a threaded hole formed at one end of the mounting slot 202. The provision of the mounting slot 202 and the threaded hole facilitates the connection of adjacent buoys 101, enabling the splicing of buoys 101. This increases the flexibility and adaptability of the buoyancy barrier system and facilitates transportation, installation, and maintenance.

[0038] Furthermore, a transfer assembly 300 is provided on the inner wall of the dam 101, and the transfer assembly 300 includes a transfer groove 301 provided on the outside of the dam 101, in which a paddle blade 302 is rotatably mounted, and a transmission blade 303 is provided below the dam 101 and fixed coaxially with the paddle blade 302. The transmission blade 303 provided at the bottom of the dam 101 will rotate under the flow of water, and drive the paddle blade 302 fixed coaxially with it to rotate. When the paddle blade 302 rotates, it will paddle floating objects near the dam 101, causing them to move in one direction, facilitating subsequent collection and cleaning.

[0039] Furthermore, a guide roller 304 is provided on the paddle blade 302. The guide roller 304 prevents floating objects from adhering to the paddle blade 302. When the floating objects come into contact with the paddle blade 302, they are likely to slide relative to each other, thereby detaching from the paddle blade 302 and quickly flowing to the place where the floating objects gather.

[0040] During use, the transmission blades 303 and the paddle blades 302 are arranged so that the floating objects will move in one direction, which is convenient for subsequent collection and cleaning. In addition, the guide rollers 304 arranged on the paddle blades 302 will cause the floating objects in contact with the paddle blades 302 to slide relative to each other, further increasing the speed at which the floating objects flow to the gathering place.

[0041] The remaining structures are the same as those of Example 2.
