Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a disc type buoy gate supporting mechanism. Background Art

[0002] The disc-type buoy gate is a water level regulating and water flow control device used in water conservancy projects. The traditional buoy gate automatically adjusts the opening and closing of the gate as the water level changes through the buoyancy of the buoy to achieve the purpose of water flow control. In the existing design, as the water level rises, the gate support structure will be subjected to increasing water flow pressure. If the supporting force cannot be automatically adjusted with the water level change, the support mechanism may be subjected to unnecessary excessive stress at low water levels, or may not be able to provide sufficient support at high water levels. This results in the gate frame being subjected to excessive stress when the water level changes greatly or the external impact force is strong, increasing the risk of material fatigue and damage. At the same time, traditional support systems often rely on external electronic monitoring equipment to adjust the support force to cope with water level fluctuations, which not only increases the complexity and maintenance cost of the system, but also reduces the reliability and adaptability of operation. Therefore, the existing buoy gate support structure has certain limitations. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-6 The present invention provides a technical solution for a disc-type floating gate support mechanism, and its detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0044] A disc type buoy gate support mechanism comprises: a gate body frame 1, a gate body 2, a buoy 3 and an anchor base 4.

[0045] The gate body frame 1 is a movable guide rail for the gate body 2. The gate body 2 is inserted into the gate body frame 1 in a direction perpendicular to the ground. The gate body 2 is a disc-type gate. When the disc-type gate is opened, the disc is arranged perpendicular to the direction of water flow, which can effectively reduce the resistance of water flow. Its structural design makes it difficult for the fluid to generate turbulence when passing through, and the flow regulation is more stable. When the gate is in a fully open state, the flow channel through which the water flows is relatively smooth, and a large water flow rate can be maintained to reduce energy loss. The float 3 is arranged on the gate body 2, and the float 3 is located below the gate body 2. The buoyancy generated by the float 3 can lift the gate body 2. When the gate is open, the top of the gate body 2 will extend from the top of the gate body frame 1. The anchor base 4 is arranged at the bottom of the gate body frame 1, and the bottom of the anchor base 4 will be buried in the ground or riverbed to ensure its stability and anti-sliding performance.

[0046] The gate support mechanism also includes: a support system and four oil supply mechanisms 6.

[0047] The support system includes four support mechanisms, which are symmetrically arranged in groups of two on the water-facing surface (upstream surface) and the water-receiving surface (downstream surface) of the gate body frame 1. Each support mechanism is composed of two support assemblies 5. The two support assemblies 5 are arranged side by side along the horizontal plane of the gate body 2, and the bottoms are aligned with each other and are located on the same horizontal plane. This symmetrical arrangement ensures that under different water flow conditions, the gate body frame 1 maintains a stable force distribution when subjected to water flow pressure, and effectively avoids the problem of lateral deviation or excessive local stress, providing all-round mechanical support. Four independent oil supply mechanisms 6 are respectively installed on the water-facing surface and the water-receiving surface of the gate body frame 1. Each oil supply mechanism 6 is connected to the corresponding two support assemblies 5 to ensure that hydraulic oil can be accurately supplied to each support assembly 5, thereby realizing independent drive and control of the support assembly 5. This design not only ensures the synchronous action of the support assembly 5, but also can be adjusted according to real-time working conditions to ensure the stability of the system under various water levels and external force conditions.

[0048] The support assembly 5 includes: a first support rod 51 , a second support rod 52 , a connecting piece 53 , a first guide wheel 54 , a second guide wheel 55 , a top plate 56 , a traction belt 57 and a support cylinder 58 .

[0049] One end of the first support rod 51 is hinged to the anchor base 4, and one end of the second support rod 52 is hinged to the gate body frame 1. The first support rod 51 and the second support rod 52 are located on the same vertical plane. The first support rod 51 and the second support rod 52 adopt the same structural design, and both are adjustable length structures. Their lengths can be flexibly adjusted according to needs to adapt to the support requirements under different working conditions. Each support rod consists of an intermediate rod 512 and two side rods 511. The intermediate rod 512 is connected to the two side rods 511 through threads. The threads of the intermediate rod 512 are bidirectional threads, that is, the rotation directions of the threads at both ends are opposite. One end is a right-hand thread, which is screwed to the side rod 511 on one side, and the other end is a left-hand thread, which is screwed to the side rod 511 on the other side. Screw connection, when the middle rod 512 rotates, due to the different thread directions, the two side rods 511 will move in opposite directions or approach each other, thereby achieving the effect of changing the overall length of the support rod. The shape of the side rod 511 adopts a high-strength cylindrical design, which has excellent bending and torsion resistance, ensuring that the support rod can still maintain good mechanical stability after adjusting the length and prevent deformation under heavy load conditions. The middle rod 512 is a polygonal structure, which is convenient for operation with a wrench. In order to ensure the stability of the support rod after adjustment, a locking device is designed on the support rod, which can firmly lock the middle rod 512 in the current position after adjusting to the expected length to prevent loosening or deformation under external force. The locking device includes but is not limited to the use of a locking nut 513. To ensure the stability of the length of the support rod after adjustment, the first support rod 51 and the second support rod 52 in each support assembly 5 are the same, and different lengths are adjusted to suit different positions. The connecting piece 53 is hinged to the far end of the first support rod 51 from the anchor base 4 and the far end of the second support rod 52 from the gate body frame 1. The first guide wheel 54 is arranged on the gate body frame 1, and the second guide wheel 55 is arranged on the anchor base 4. The end of the top plate 56 is hinged to the gate body frame 1. One end of the traction belt 57 is connected to the connecting piece 53, and the other end of the traction belt 57 is connected to the far end of the top plate 56 from the gate body frame 1 via the first guide wheel 54 and the second guide wheel 55. The traction belt 57 has high tensile strength and low elongation. The traction belt 57 should have The lower elongation rate can keep its length unchanged when bearing load, ensuring the efficiency of force transmission. The support cylinder 58 is arranged on the anchor base 4 in a direction perpendicular to the ground. The top output end of the support cylinder 58 abuts against the bottom surface of the top plate 56. A spherical joint is installed between the top output end of the support cylinder 58 and the bottom surface of the top plate 56, including but not limited to the installation of a spherical joint. The joint can provide adaptive adjustment when the top plate 56 has an angular deviation or the thrust of the support cylinder 58 is not completely vertical. The vertically arranged support cylinder 58 can directly withstand the vertical pressure from the top plate 56, reducing the interference of lateral force. The thrust of the hydraulic cylinder can be transmitted along the axial direction of the cylinder, ensuring the mechanical efficiency of the support system. In the two support components 5 of the same support mechanism,The connection points of the two second support rods 52 and the gate frame 1 are at different heights, so that the two groups of first support rods 51 and second support rods 52 have different inclination angles, which can optimize the force distribution of the structure and the stability of the system, and can provide variable pulling force and supporting force at different positions of the gate frame 1 under different water depths. At the same time, the two support cylinders 58 under the same support mechanism are connected to the same oil supply mechanism 6. According to Pascal's principle, the pressure of the liquid is equal at all places in the closed system. Therefore, when multiple cylinders are connected in series in the same pipeline, the pressure in the hydraulic system will be evenly transmitted to each cylinder through the hydraulic oil. Therefore, the oil supply by the same oil supply mechanism 6 can ensure that the pressure is balanced between the two support cylinders 58.

[0050] The portion of the traction belt 57 located between the connecting piece 53 and the first guide wheel 54 is perpendicular to the force direction of the hinge point of the first support rod 51 and the second support rod 52, which can maximize the transmission efficiency of the traction force. The vertical force design can reduce the generation of lateral force and prevent unnecessary force dispersion or increase in friction, thereby ensuring that the system can be smoothly adjusted when the load changes.

[0051] In the unstressed state, the first support rod 51 and the second support rod 52 located on the water-facing side of the gate body frame 1 are on the same axis, and the first support rod 51 and the second support rod 52 located on the water-receiving side of the gate body frame 1 have an angle, and the angle points in the direction away from the gate body frame 1. On the water-facing side of the gate body frame 1, when the first support rod 51 and the second support rod 52 gradually change from being located on the same axis (that is, the two rods are in a straight line) to having an angle, and the angle points in the direction of the gate body frame 1, as the angle gradually increases, the distance between the outer ends (distal ends) of the first support rod 51 and the second support rod 52 will gradually shorten. This geometric change directly This directly leads to an increase in the tension between the gate body frame 1 and the anchor base 4. On the back surface of the gate body frame 1, when the first support rod 51 and the second support rod 52 change from a state of having an angle, and the angle points in a direction away from the gate body frame 1, to a coaxial state, that is, the angle gradually increases, the distance between the outer ends (distal ends) of the first support rod 51 and the second support rod 52 will gradually increase. This geometric change directly leads to an increase in the supporting force between the gate body frame 1 and the anchor base 4, so that as the water level rises on the water-facing surface of the gate body frame 1, the tension generated by the support assembly 5 gradually increases, and the supporting force generated by the support assembly 5 on the back surface of the gate body frame 1 gradually increases.

[0052] A limit device is provided at the hinge point of the first support rod 51 and the second support rod 52, and the limit device is used to limit the angle variation range between the support rods to ensure that the system always maintains a safe mechanical state during operation and avoids excessive folding or exceeding the designed angle range.

[0053] The oil supply mechanism 6 includes an oil supply cylinder 61 , a piston rod 62 , an oil delivery pipe 63 , a connecting rod 64 , an auxiliary rod 65 , a push rod 66 and a spring 67 .

[0054] The oil supply cylinder 61 is arranged on the gate body frame 1, the cylinder cavity of the oil supply cylinder 61 is perpendicular to the ground, and the cavity opening is located at the bottom of the oil supply cylinder 61, the piston rod 62 is plugged into the bottom of the oil supply cylinder 61, and the oil supply is controlled by the push of the piston rod 62. The oil delivery pipe 63 is arranged between the oil supply cylinder 61 and the supporting cylinder 58. The oil delivery pipe 63 is a hydraulic oil delivery channel between the oil supply cylinder 61 and the supporting cylinder 58, which is used to transfer hydraulic oil. The oil delivery pipe 63 is connected to the top of the oil supply cylinder 61 and the supporting cylinder 58. To ensure that the hydraulic oil in the oil cylinder can flow smoothly into the supporting oil cylinder 58, one end of the connecting rod 64 is connected to the bottom of the piston rod 62, and the other end of the connecting rod 64 extends above the top surface of the oil supply cylinder 61. To ensure the stable sliding of the piston rod 62, the connecting rod 64 can be symmetrically arranged on both sides of the piston rod 62 to avoid the unsmooth movement of the piston rod 62 due to uneven force. The auxiliary rod 65 is arranged perpendicular to the ground at the far end of the connecting rod 64 away from the bottom of the piston rod 62, and a limited position convex is arranged on the top of the auxiliary rod 65. The push rod 66 is ensured to slide within the length of the auxiliary rod 65. One end of the push rod 66 is sleeved on the outer wall of the auxiliary rod 65. The push rod 66 is located directly above the gate body 2. During the rising process of the gate body 2, the push rod 66 is pushed to move synchronously upward. At the same time, the auxiliary rods 65 on both sides of the gate frame 1 are connected by the same push rod 66. The push rod 66 is pushed by the gate body 2, so that the oil supply mechanisms 6 on both sides of the gate frame 1 operate simultaneously. The spring 67 is sleeved on the outer wall of the auxiliary rod 65, and the spring 67 is located at the limit position. Between the protrusion and the push rod 66, when the piston rod 62 has not moved to the maximum limit of the oil supply cylinder 61, the spring 67 is in an uncompressed state. At the same time, the push rod 66 will drive the piston rod 62 to move synchronously through the connecting rod 64, and squeeze the hydraulic oil in the oil supply cylinder 61 into the supporting cylinder 58. When the piston rod 62 moves to the maximum limit of the oil supply cylinder 61, the gate body 2 will continue to move upward. At this time, the spring 67 is compressed. When the push rod 66 moves to the maximum limit at the top of the auxiliary rod 65, the gate is in a fully open state.

[0055] The cylinder diameter of the oil supply cylinder 61 is smaller than that of the supporting cylinder 58, indicating that the oil supply cylinder 61 provides a smaller volume of hydraulic oil, but can transmit sufficient pressure through the hydraulic principle to push the supporting cylinder 58. Based on the pressure conversion principle in the hydraulic system, efficient pressure transmission and system stability are achieved.

[0056] The oil storage capacity of the oil supply cylinder 61 is greater than the total oil storage capacity of the two connected supporting cylinders 58. The two supporting cylinders 58 require a large amount of hydraulic oil for thrust output at the same time. The oil supply cylinder 61 can provide sufficient hydraulic oil supply, maintain the continuity of oil supply, and prevent oil supply terminal.

[0057] The sum of the displacement of the piston rod 62 and the displacement of the push rod 66 on the auxiliary rod 65 matches the displacement of the gate body 2 .

[0058] A guide plate 7 is arranged on the anchor base 4. The guide plate 7 wraps the support mechanism to reduce the impact of the water flow on the support mechanism when the water flows through, and prevents the accumulation of debris and silt in the water, thereby protecting the stability and life of the support system. The guide plate 7 adopts a streamlined structure, which can guide the water flow to bypass the support mechanism along a smooth path, effectively reducing the frontal impact of the water flow on the support structure. The guide plate 7 can not only guide the water flow, but also form a specific water flow channel. Through the flushing effect of the water flow, it prevents debris (such as branches, plastics, etc.) and silt in the water from accumulating near the support mechanism, thereby ensuring the cleanliness and stability of the support structure.

[0059] Due to being underwater for a long time, the bearings, rotating parts (such as the rotating parts of the first guide wheel 54) and supporting parts need to have extremely strong corrosion resistance, which can be achieved by adding anti-corrosion coatings on the surface of the equipment. Since it is inconvenient to perform conventional lubrication and maintenance in the underwater environment, the rotating parts and bearings of the equipment adopt a self-lubricating design. In order to prevent water from entering the interior of the equipment, the bearing parts of the rotating parts and supporting parts need to have excellent waterproof sealing performance. In underwater equipment, organisms (such as algae, shellfish, etc.) are easy to attach to the surface and affect the operation of the equipment. Therefore, anti-biological attachment materials or coatings (such as copper-based coatings, anti-fouling paints, etc.) can be used on the surface of the equipment to prevent organisms from attaching to the surface of the equipment.

[0060] Working principle:

[0061] In the initial state, the first support rod 51 and the second support rod 52 located on the water-facing side of the gate body frame 1 are in a coaxial state, and at the same time, the output end of the support cylinder 58 located on the water-facing side of the gate body frame 1 is in an unextended state, generating a pulling force on the gate body frame 1, and there is an angle between the first support rod 51 and the second support rod 52 located on the water-receiving side of the gate body frame 1, and the output end of the support cylinder 58 located on the water-receiving side of the gate body frame 1 is in an unextended state, but the traction belt 57 is still in a taut state, so that the angle between the first support rod 51 and the second support rod 52 located on the water-receiving side of the gate body frame 1 has a tendency to increase, thereby generating a supporting force on the water-receiving side of the gate body frame 1, thereby achieving a supporting effect on the entire gate.

[0062] When the water level rises, the gate body 2 will rise under the action of the buoy 3, and the top of the gate body 2 will move out from the top of the gate frame 1, pushing the push rod 66 to move up synchronously, and the connecting rods 64 connected on both sides of the push rod 66 will push the piston rod 62 to move up, so that the oil supply cylinders 61 on both sides of the gate frame 1 will transport the hydraulic oil to the corresponding supporting cylinders 58 through the oil pipes 63. At this time, the output ends of the two supporting cylinders 58 located on the water-facing surface of the gate frame 1 will extend, lift up the top plate 56, and pull the traction belt 57, and cooperate with the use of the first guide wheel 54 and the second guide wheel 55 to make the support cylinders 58 located on the water-facing surface of the gate frame 1 The first support rod 51 and the second support rod 52 on the side are changed from a coaxial line state to a state with an angle, and the angle points to the direction of the gate body frame 1. At this time, the pulling force acting on the gate body frame 1 will increase with the rise of water level, and the oil supply cylinder 61 located on the back water side of the gate body frame 1 pushes the top plate 56 to flip up, and the traction belt 57 is pulled. The first support rod 51 and the second support rod 52 located on the back water side of the gate body frame 1 are changed from a state with an angle to a coaxial line state. At this time, the supporting force acting on the back water side of the gate body frame 1 will increase with the rise of water level, so as to achieve a good supporting effect for the gate as a whole.
