However, when the pontoon is tilted by the fluctuations in the water, the pontoon cannot automatically correct itself, resulting in low reliability of the device. Although the buffer plate arranged in the device weakens the flow of water inside the pontoon to a certain extent, it still cannot eliminate the flow of water and still affects the stability of the pontoon.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please see attached Figure 1 -Attached Figure 4 The auxiliary sinking support device of the wind tower includes a pontoon 1, the outer wall of the pontoon 1 is provided with a self-balancing component, the interior of the pontoon 1 is provided with a compression mechanism, the self-balancing component includes four first obstruction plates 2 arranged around the periphery of the pontoon 1, a second obstruction plate 201 is fixed on the side of the first obstruction plate 2 away from the pontoon 1, the first obstruction plate 2 and the second obstruction plate 201 are both V-shaped structures, a counterweight block 202 is fixed between the first obstruction plate 2 and the second obstruction plate 201, and the counterweight block 202 can be a solid iron block or a solid marble.

[0022] In the embodiment, three sliding rods 203 are fixed to one side of the first obstructed plate 2 close to the pontoon 1, and a sliding sleeve 204 is slidably provided on the outer wall of the sliding rod 203, and one end of the sliding sleeve 204 is fixed to the outer wall of the pontoon 1. Through the arrangement and use of the first obstructed plate 2 and the second obstructed plate 201, and the combination of water resistance and the lever principle, the pontoon 1 has an automatic balancing function during the sinking of the water, which prevents the pontoon 1 from being unable to correct itself after being tilted by water waves, thereby increasing the reliability of the device.

[0023] In an embodiment, a first limiting ring 3 is fixed to one end of the outer wall of the sliding rod 203 close to the sliding sleeve 204, and a second limiting ring 301 is fixed to one end of the sliding sleeve 204 close to the sliding rod 203. Through the setting and use of the first limiting ring 3 and the second limiting ring 301, the sliding rod 203 can be limited to prevent the sliding rod 203 from detaching from the inside of the sliding sleeve 204.

[0024] In the embodiment, a piston 302 is fixed to one end of the sliding rod 203 close to the sliding sleeve 204, and the piston 302 is interference fit with the inside of the sliding sleeve 204. The interference fit between the piston 302 and the inside of the sliding sleeve 204 enables the sliding rod 203 to have a certain damping effect when moving inside the sliding sleeve 204, thereby preventing the sliding rod 203 from sliding too fast and affecting the self-balancing of the self-balancing assembly.

[0025] In an embodiment, the compression mechanism includes an extension hole 4 opened on the top surface of the buoyancy box 1, a compression plate 401 is fixed to the inner top surface of the buoyancy box 1, a rubber sleeve 402 is fixed to the bottom surface of the compression plate 401, an inflation joint 403 is fixed to the top surface of the compression plate 401, the inflation joint 403 is connected to the inner cavity of the rubber sleeve 402, the inflation joint 403 is fixed to the inside of the extension hole 4 through a sealant, a water injection port 404 is fixed to the top surface of the buoyancy box 1, and the outer walls of the inflation joint 403 and the water injection port 404 are both threadedly connected with a sealing cover. Through the arrangement and use of the compression plate 401 and the rubber sleeve 402, after a certain amount of water is injected into the buoyancy box 1, the water can be compressed by the compression plate 401 and the rubber sleeve 402, so that the water fills the inner cavity of the buoyancy box 1, effectively preventing water from flowing in the inner cavity of the buoyancy box 1 and affecting the stability of the buoyancy box 1 during the sinking process.

[0026] In an embodiment, the length of the first obstructed plate 2 is greater than that of the second obstructed plate 201. Since the length of the first obstructed plate 2 is greater than that of the second obstructed plate 201, the first obstructed plate 2 is subjected to greater resistance than that of the second obstructed plate 201, so that when the pontoon 1 sinks, the first obstructed plate 2, the second obstructed plate 201 and the counterweight 202 extend outward to the maximum distance, thereby increasing the balance of the device.

[0027] Working principle: When in use, open the sealing cover between the inflation joint 403 and the water injection port 404, then inject a certain amount of water into the buoyancy tank 1 through the water injection port 404, connect the inflation pump to the inflation joint 403, and then inflate the inside of the rubber sleeve 402, so that the rubber sleeve 402 continuously expands and compresses the water inside the buoyancy tank 1, so that the water inside the buoyancy tank 1 fills the buoyancy tank 1, effectively preventing water from flowing in the inner cavity of the buoyancy tank 1 and affecting the stability of the buoyancy tank 1 during the sinking process. It is worth noting that since the rubber sleeve 402 is inside the buoyancy tank 1, the water pressure will not act on the rubber sleeve 402, so the rubber sleeve 402 will not be compressed by the water pressure and become smaller, and then the buoyancy tank 1 is sunk into the water. When the buoyancy tank 1 sinks in the water, During the process, the first obstruction plate 2 and the second obstruction plate 201 will be subject to the resistance of water from bottom to top. Since the length of the first obstruction plate 2 is greater than that of the second obstruction plate 201, the resistance encountered by the first obstruction plate 2 is greater than that of the second obstruction plate 201, so that when the pontoon 1 sinks, the first obstruction plate 2, the second obstruction plate 201 and the counterweight 202 extend outward to the maximum distance, thereby increasing the balance of the device. When the pontoon 1 tilts in the water, the angle between the second obstruction plate 201 at the inclined end and the direction of water flow suddenly decreases, so that the water resistance encountered by the second obstruction plate 201 increases significantly. The angle between the first obstruction plate 2 at one end of the anti-inclined end and the direction of water flow also decreases, and the water resistance encountered also increases significantly. This causes the first obstruction plate 2 at the inclined end of the pontoon 1 to , the second blocked plate 201 and the counterweight 202 shrink toward the inside of the pontoon 1, while the first blocked plate 2, the second blocked plate 201 and the counterweight 202 at the reverse tilted end maintain their original state. At this time, since the counterweight 202 at the tilted end is close to the pontoon 1, and the counterweight 202 at the end opposite to the tilted end is far from the pontoon 1, a lever principle is formed, causing the pontoon 1 to tilt toward the end opposite to the tilted end, until the pontoon 1 is no longer tilted, the angle between the second blocked plate 201 at the tilted end and the first blocked plate 2 at the reverse tilted end and the water flow direction returns to normal, and the water resistance also returns to normal, causing the first blocked plate 2, the second blocked plate 201 and the counterweight 202 at the tilted end of the pontoon 1 to extend to the maximum distance outside the pontoon 1 again, thereby The self-balancing process is realized. Through the setting and use of the first limit ring 3 and the second limit ring 301, the sliding rod 203 can be limited to prevent the sliding rod 203 from escaping from the inside of the sliding sleeve 204. The piston 302 is interfered with the inside of the sliding sleeve 204, so that the sliding rod 203 has a certain damping effect when moving inside the sliding sleeve 204, preventing the sliding rod 203 from sliding too fast and affecting the self-balancing of the self-balancing assembly. The length of the first blocked plate 2 is greater than that of the second blocked plate 201, and the resistance of the first blocked plate 2 is greater than that of the second blocked plate 201. When the buoy 1 sinks, the first blocked plate 2, the second blocked plate 201 and the counterweight block 202 extend outward to the maximum distance, thereby increasing the balance of the device.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
