[0024] See also Figures 1 to 6 As shown, a guide wheel structure of a buoy gate includes a gate body 1, a lifting device and a guide device. Gate piers are arranged on both sides of the gate body 1, and the gate body 1 is limited by the gate piers. The gate body 1 is generally made of steel or other corrosion-resistant materials. The amount of water flow is adjusted by moving the gate body 1 up and down. The lifting device is mainly used to drive the lifting and lowering movement of the gate body 1. A control system is arranged in the lifting device, which not only realizes remote monitoring, but also can accurately control the rising and falling positions of the gate body 1. The guide device is used to guide the gate body 1 to maintain the correct direction and position during the rising or falling process, so that the gate body 1 can move smoothly along the preset track to avoid the gate body 1 from deflecting or shaking.

[0025] The guide device includes a guide rail 2 and a guide wheel 3. The guide rail 2 is vertically arranged in the gate piers on both sides of the gate body 1. One end of the guide rail 2 is a fixing portion 6, which is arranged inside the gate pier. The other end of the guide rail 2 is a sliding groove 7, which is exposed from the gate pier. The cross section of the sliding groove 7 is a "concave" type. The guide wheel 3 is arranged in the sliding groove 7. The guide wheel 3 includes a connecting end 4 and a limiting end 5. The connecting end 4 of the guide wheel 3 is connected to the gate body 1. The limiting end 5 of the guide wheel 3 is located in the sliding groove 7. The limiting end 5 is hemispherical. By sliding the hemispherical limiting end 5 in the sliding groove 7, the phenomenon of wheel blocking and rail jamming can be effectively avoided. The connecting end 4 and the limiting end 5 are an integrally formed structure. Since the limiting end 5 of the guide wheel 3 located in the sliding groove 7 is hemispherical, the limiting end 5 is in the sliding groove 7. The inner portion will not be completely fitted with the sliding groove 7, and there is a gap between the limit end 5 and the sliding groove 7, which is a movable space. Through the movable space, the gate body 1 can be more suitable for different water levels and meet the operation requirements under different load conditions, ensuring that the gate body 1 can operate flexibly and reliably. The activity space can effectively avoid the problem that friction and water flow resistance affect the smoothness of the lifting and lowering of the gate body 1. If the guide wheel 3 and the guide rail 2 are too fitted, the friction will increase, and in a dynamic environment such as water flow, this friction will become more unpredictable, and the activity space can also help the lubricating fluid to be evenly distributed. If the guide wheel 3 and the guide rail 2 are too fitted, the lubricating fluid cannot be evenly distributed, and it is difficult to penetrate between the contact surfaces, resulting in a weakened lubrication effect, thereby making the rising and falling of the gate body 1 more difficult.

[0026] A rotating kit 8 is also provided on the limit end 5 of the guide wheel 3. The rotating kit 8 is in the shape of a hemisphere with a hollow interior. The rotating kit 8 is sleeved on the limit end 5, and the rotating kit 8 can rotate around the limit end 5. The rotating kit 8 can reduce the friction between the limit end 5 and the sliding groove 7, thereby increasing the service life of the limit end 5 and the sliding groove 7, and can improve the smoothness of the gate body 1 when moving up and down. Through holes 9 are provided on the rotating kit 8. The number of through holes 9 is multiple and evenly distributed on the rotating kit 8. The lubricating liquid can be transferred to the activity space through the through holes 9, so as to lubricate the sliding groove 7, and the rotation of the rotating kit 8 can also make the through holes 9 drive the lubricating liquid to be evenly distributed.

[0027] Internal spaces are provided in the limit end 5 and the connection end 4 of the guide wheel 3. The internal space of the connection end 4 is a liquid injection pipe 10, and the internal space of the limit end 5 is a heating chamber 11. A first one-way valve 12 is provided at the connection between the liquid injection pipe 10 and the heating chamber 11. The first one-way valve 12 can prevent the backflow of the lubricating liquid. A telescopic cylinder 13 is provided in the liquid injection pipe 10. The telescopic cylinder 13 is connected to the lifting device. The control system in the lifting device can control the telescopic cylinder 13 to perform telescopic movement. A sealing plug 14 is provided on 13, and the sealing plug 14 divides the injection pipeline 10 into two parts. Lubricating liquid is stored between the sealing plug 14 and the first one-way valve 12, so that the sealing plug 14 is controlled to push the lubricating liquid, so that the lubricating liquid is discharged from the first one-way valve 12 and enters the heating chamber 11. A second one-way valve 15 is provided on the side wall of the heating chamber 11. The first one-way valve 12 and the second one-way valve 15 are both ball one-way valves or swing one-way valves. When the inlet pressure decreases, the first one-way valve 12 and the second one-way valve 15 The one-way valve 15 will automatically close to prevent backflow. A heating ball 16 is arranged in the heating chamber 11. The heating ball 16 is a hemispherical shape with a hollow interior. The heating ball 16 is made of pure copper. The heating ball 16 is arranged in the heating chamber 11. The heating ball 16 can be heated by electric current. Since the heating ball 16 is made of pure copper, the heating ball 16 will expand after being powered on and heated, thereby squeezing the lubricating fluid in the heating chamber 11 and discharging it from the heating chamber 11 through the second one-way valve 15. A The auxiliary positioning ring 17 is sleeved on the outer surface of the heating ball 16, and the auxiliary positioning ring 17 is connected to the inner wall of the heating chamber 11, so that the heating ball 16 is stabilized in the heating chamber 11, and the auxiliary positioning ring 17 is made of fluororubber. The oil resistance and corrosion resistance of the fluororubber material can make the auxiliary positioning ring 17 immersed in the lubricating liquid for a long time, and the high temperature resistance and elasticity of the fluororubber material make it possible to prevent the auxiliary positioning ring 17 from melting or breaking when the heating ball 16 is powered on and heated to expand.

[0028] An anti-drop-off plate 18 is also provided on the sliding groove 7. The anti-drop-off plate 18 and the sliding groove 7 are an integrally formed structure. The anti-drop-off plates 18 are respectively arranged on both sides of the sliding groove 7. When the limiting end 5 of the guide wheel 3 is located in the sliding groove 7, the two anti-drop-off plates will block the limiting end 5, so that the limiting end 5 cannot fall off from the sliding groove 7. At this time, the limiting end 5 of the guide wheel 3 is located between the anti-drop-off plates 18 on both sides. A cleaning brush 19 is provided on the anti-drop-off plate 18. The cleaning brush 19 is located on the side wall of any one of the two anti-drop-off plates 18, and the cleaning brush 19 can contact with the limiting end 5 of the guide wheel 3. The cleaning brush 19 is made of polypropylene, abbreviated as PP material. The extremely low water absorption rate of PP material can prevent it from absorbing the lubricating liquid, and will not affect the flow effect of the lubricating liquid. It is also not afraid of long-term immersion. Since the cleaning brush 19 is only provided on the anti-slip plate on one side, when the cleaning brush 19 brushes the rotating kit 8 to clean it, it will also generate friction with the rotating kit 8, causing the rotating kit 8 to rotate so that the lubricating liquid flows out from the through hole 9 and is evenly distributed on the outside of the rotating kit 8. The lubricating liquid is in contact with the sliding groove 7 through the activity space, thereby enhancing the lubrication effect.

[0029] During use, since the temperature in the north is relatively low in winter, the lubricating fluid is prone to freezing. At this time, the heating ball 16 in the heating chamber 11 can be heated to make the heating ball 16 heat up and expand. When the heating ball 16 heats up, the lubricating fluid in the heating chamber 11 is heated to thaw the lubricating fluid in the heating chamber 11. Moreover, since the volume of the heating ball 16 expands due to the heat, the lubricating fluid inside the heating chamber 11 is squeezed. After being squeezed, the lubricating fluid cannot return to the injection pipe 10 from the first one-way valve 12. Therefore, the lubricating fluid can only be discharged from the second one-way valve 15 and then discharged through the through hole 9 on the rotating kit 8. The heating ball 1 6 gradually cools down after stopping heating, and its volume shrinks. At this time, the pressure in the heating chamber 11 becomes smaller. At this time, the telescopic cylinder 13 can be started, and the lubricating liquid in the injection pipe 10 enters the heating chamber 11 through the telescopic cylinder 13 through the first one-way valve 12. When the lubricating liquid in the heating chamber 11 fills the heating chamber 11, the first one-way valve 12 is affected by the pressure change and automatically closes to prevent the lubricating liquid from flowing back. When it is necessary to lubricate the sliding groove 7 and the rotating kit 8, it is only necessary to re-energize and heat the heating ball 16. The lubricating liquid can make the gate body 1 drive the guide wheel 3 to rise or fall more smoothly, and on the upper side of the gate body 1 During the process of rising and falling, since the limit end 5 in the guide wheel 3 is located in the sliding groove 7 in the guide rail 2, and since the anti-slip plate 18 and the sliding groove 7 are integrally formed, the limit end 5 will not be separated from the sliding groove 7, thereby guiding the movement of the gate body 1, so that the gate body 1 can only move along the direction of the guide rail 2 when rising and falling, and since the limit end 5 of the guide wheel 3 is in the shape of a hemispherical shape, and the limit end 5 of the guide wheel 3 is located inside the sliding groove 7 of the guide rail 2, the phenomenon of wheel blocking and rail jamming can be effectively avoided. When the limit end 5 moves in the sliding groove 7, the cleaning part on the rotating kit 8 and the anti-slip plate 18 The brush 19 contacts the anti-slip plate 18 on one side, thereby increasing the friction. Since the cleaning brush 19 is only provided on one side of the anti-slip plate 18, when the limit end 5 moves up and down, the rotating sleeve 8 will rotate due to the friction with the cleaning brush 19. When the rotating sleeve 8 rotates, the through hole 9 on the rotating sleeve 8 will rotate around the limit end 5, so that the lubricating fluid between the rotating sleeve 8 and the limit end 5 is discharged from the through hole 9, and the lubricating fluid enters the sliding groove 7 to lubricate the sliding groove 7, and can lubricate the rotating sleeve 8 at the same time, so that the rotation of the rotating sleeve 8 is more flexible and free, and the limit end 5 drives the rotating sleeve 8 to move in the sliding groove 7 more smoothly.

[0030] 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.
