Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a multi-element self-balancing driven double-fish type tide-blocking floating gate and an operation method thereof. Background Art

[0002] The gate is an important part of hydraulic structures and a key device for water storage, flow regulation and discharge control. Traditional tide gates have complex structures and are difficult to open and close. They are prone to problems such as large opening and closing resistance and poor stability under high water pressure differences. Therefore, it is of great significance to design a tide gate with a reasonable structure, convenient opening and closing, and stable operation.

[0003] Arch structures have been widely used in engineering fields such as buildings and bridges. Due to their reasonable structural system, they are more widely used in large-span structures and spatial structures. Arch structures convert the bending moment formed by external loads into axial forces of components through arch curves, which can give full play to the performance of materials. Due to the mechanical properties of the arch, its gate bearing structure mainly bears axial forces, and the force is uniform along the span. In the case of large spans, not only the materials are economical, but also the shape is beautiful and the gate structure is simple to arrange.

[0004] For example, Chinese patent CN119145364A proposes a large-span folding arc-shaped tide-blocking floating gate structure. The gate unit is designed to be divided into two layers, upper and lower, which can be folded and folded in the gate reservoir. Each gate unit includes an upper tide-blocking floating gate, a lower tide-blocking floating gate and an arc-shaped foundation. The radius of the upper tide-blocking floating gate is larger than that of the lower tide-blocking floating gate. One end of the upper tide-blocking floating gate and the lower tide-blocking floating gate are both hinged in the load-bearing pier on the shore side, and are arranged concentrically in different positions. The arc-shaped foundation is formed by the upper tide-blocking floating gate and the lower tide-blocking floating gate. The foundation extends from the gate reservoir to the center of the river channel. The upper and lower tide-blocking floating gates rotate and move from the edge of the gate reservoir to the center of the river channel around their hinge points along the arc foundation. By controlling the water injection volume of the upper and lower tide-blocking floating gates, the ends of the upper and lower tide-blocking floating gates away from the hinge points sink to the arc foundation. The arc foundation is used to provide upward support for the upper and lower tide-blocking floating gates in the tide-blocking state. This solution can achieve large-span water retention and reduce the structural footprint, but in actual applications it is difficult to ensure accurate and stable opening and closing control of the upper and lower tide-blocking floating gates. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a multi-element self-balancing driven double fish type tide-blocking floating gate and its operation method, which can open and close the gate efficiently, accurately and stably.

[0006] The object of the present invention can be achieved through the following technical scheme: a multi-element self-balancing driven double fish-type tide-blocking floating gate, including an arched gate body, the arched gate body is divided into two fish-type arched structures arranged symmetrically on the left and right, the fish-type arched structure is provided with a plurality of adjustable opening and closing flow holes, the belly part of the fish-type arched structure is provided with a buoyancy box, the tail part of the fish-type arched structure is provided with a weight, the tail part of the fish-type arched structure is connected to a motor drive device, and the motor drive device transmits power to the tail part to rotate, so as to realize the opening and closing action of the arched gate body.

[0007] Furthermore, a floating gear is provided at the fishtail portion of the fish-type arch structure, and the floating gear is connected to the motor drive device.

[0008] Furthermore, the fishtail portion of the fish-type arch structure is provided with a pin-tooth transmission mechanism, and the pin-tooth transmission mechanism is connected to the motor drive device.

[0009] Furthermore, the flow hole is provided with a rotary door, and the opening and closing of the flow hole is controlled by the rotary door.

[0010] Furthermore, a track is laid under the fishtail portion of the fish-type arch structure, and an anti-hook device is provided.

[0011] Furthermore, a ball joint is provided at the rotation center of the fishtail portion of the fish-type arch structure, and a centering rotation center column is provided.

[0012] Furthermore, a high polymer anti-friction material is used to realize a sliding surface at a position where the fishtail portion of the fish-type arch structure contacts the track.

[0013] Furthermore, rollers are used to realize the rolling surface at the position where the fishtail portion of the fish-type arch structure contacts the track.

[0014] A method for operating a multi-element self-balancing driven double fish type tide-blocking floating gate comprises a gate closing operation process and a gate opening operation process realized by a motor driving device through forward and reverse rotation.

[0015] Furthermore, the gate closing operation process is specifically as follows: the motor drive device runs forward to transmit power to the fishtail parts of the two fish-type arch structures to drive the left and right fish-type arch structures to rotate, and at the same time open the flow hole to reduce the rotation resistance caused by the water pressure difference. The arch gate body rotates toward the river side until the front end surfaces of the two are in contact and overlap, and the two fish-type arch structures form an arch on the outside to cut off the river for tide blocking operations. At this time, the gate is in a closed state, and the arch side is in contact with the upstream of the river to withstand water pressure. In this process, the buoyancy of the buoyancy box and the weight of the fishtail cooperate to ensure that the arch gate body rotates smoothly and closes;

[0016] The gate opening operation process is specifically as follows: the motor drive device runs in reverse to transmit power to the fishtail parts of the two fish-type arch structures to drive the left and right fish-type arch structures to rotate, the flow hole is in an open state, and the arch gate body rotates toward the road side until the axis of the arch gate body is parallel to the river channel edge line. At this time, the gate is in a fully open state.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The present invention designs two left-right symmetrical fish-shaped arch structures as the main body of the arch door to realize a double-door gate structure, and arranges a plurality of flow holes that can be adjusted to open and close in the fish-shaped arch structure, a buoyancy box is arranged in the belly part of the fish, and a ballast weight is provided in the tail part. The flow holes are used to adjust the water pressure difference and reduce the opening and closing resistance, and the buoyancy box and the ballast weight are used to ensure the axial stability during the opening and closing process. Therefore, by adjusting the buoyancy, water inlet and outlet, and the ballast weight at the end of the fish tail section, the arch door can be realized in multiple dynamic self-balancing under different water levels, including ballast weight self-balancing, driving force self-balancing and posture self-balancing, which can effectively improve the efficiency, stability and accuracy of gate opening and closing.

[0019] The present invention arranges a floating gear or pin-tooth transmission mechanism connected to a motor drive device at the fishtail portion of the fish-type arch structure, so that the motor drive device is used to transmit power to the floating gear or pin-tooth transmission mechanism to drive the left and right fish-type arch structures to rotate. Through the floating gear meshing or pin-tooth driving method, the opening and closing accuracy can be effectively improved, and the adaptability is better.

[0020] The present invention lays a track under the fishtail portion of the fish-type arch structure and arranges an anti-hook device, so that the fishtail section of the arch door body is always in contact with the track, ensuring the reliability of the opening and closing process.

[0021] The present invention arranges a ball joint at the rotation center position of the fishtail part of the fish-type arch structure, and is provided with a centering rotation center column, which can ensure the stability of the opening and closing process, adapt to the floating and swinging during the opening and closing process, and realize posture self-balancing.

[0028] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Embodiment 1

[0030] like Figure 1 As shown, a multi-element self-balancing driven double fish type tide-blocking floating gate, the arch gate body 1 is composed of two left-right symmetrically arranged fish-type arch structures to convert water pressure into pressure of the arch axis. When the two fish-type arch structures, i.e., the arch gate body 1, rotate toward the river side until the front end surfaces contact and overlap, an arch will be formed on the outside of the arch gate body 1, and the gate is in a closed state at this time; when the arch gate body 1 rotates until its axis is parallel to the river bank, the gate is in an open state.

[0031] The main body 1 of the arched door has several flow holes 2 built in, and the opening and closing of the flow holes are controlled by a rotary door to adjust the water pressure difference. A buoyancy box 3 is provided at the belly of the fish-shaped arched structure, and the buoyancy is used to ensure the axial stability of the arched door during the opening and closing process. The tail section of the fish-shaped arched structure is provided with a weight 4, so that the dynamic balance of the arched door at different water levels can be achieved by adjusting the buoyancy, water inlet and outlet, and the weight 4 at the end of the tail section of the main body 1 of the arched door.

[0032] like Figure 2 As shown, a track 7 is laid under the arch door body 1, and an anti-hook device is provided to ensure that the fishtail section of the arch door body 1 is always in contact with the track 7 and prevent the fishtail section from being separated from the track 7. In addition, the contact surface between the fishtail and the track 7 is designed to adopt a high polymer anti-friction material or a roller to achieve low-friction movement. A ball hinge 8 is provided in the rotation center of the fishtail of the arch door 1, and a centering rotation center column is provided to adapt to the up and down floating and left and right swinging during the opening and closing process, thereby ensuring the stability of the arch door opening and closing process.

[0033] The arch door body 1 is opened and closed by the fishtail. Figure 3 As shown, in this embodiment, the opening and closing method adopts the meshing drive of the floating gear 5, and the floating gear 5 is connected to the motor drive device.

[0034] In actual applications, the driving system of the arch door body 1 can also automatically adjust the motor output torque according to the change of water pressure to achieve balance with the water pressure. At the same time, it can adjust the number of motor drive devices involved in the work according to the size of the opening and closing torque to achieve self-balancing of the driving force.

[0035] The operation method of the above-mentioned double fish-type tide-blocking floating gate includes a gate closing operation process and a gate opening operation process, wherein the gate closing operation process is: the motor driving device transmits power to the floating gear 5 to drive the left and right fish-type arch structures to rotate, the flow hole 2 in the arch gate is opened to reduce the rotation resistance caused by the water pressure difference, and the arch gate body 1 rotates toward the river side until the front end surfaces of the two contact and overlap, and the outer sides of the two fish-type arch structures will form an arch to cut off the river for tide-blocking operations. At this time, the gate is in a closed state, and the arch side contacts the upstream of the river and bears the water pressure. Through the buoyancy of the buoyancy box 3 and the cooperation of the fish tail weight 4, it is ensured that the arch gate body 1 rotates smoothly and closes;

[0036] The gate opening operation process is as follows: the motor drive device runs in reverse, transmitting power to the floating gear 5 to drive the left and right fish-type arch structures to rotate, the flow hole 2 in the arch gate is also in an open state, and the arch gate body 1 rotates toward the road side until the axis of the arch gate body 1 is parallel to the river edge line. At this time, the gate is in a fully open state.

[0037] Embodiment 2

[0038] In this embodiment, Figure 4 As shown, the opening and closing mode is driven by a pin gear transmission mechanism 6, and the pin gear transmission mechanism 6 is connected to the motor drive device. The other structures of this embodiment are the same as those of the first embodiment. During the gate closing operation or the gate opening operation, the motor drive device transmits power to the pin gear transmission mechanism 6 to drive the left and right fish-shaped arch structures to rotate.

[0039] In summary, the multi-element self-balancing driven double fish type tide-blocking floating gate proposed in this scheme has the advantages of reasonable structure and uniform force, and can effectively resist water pressure. Its flow hole design can reduce the opening and closing resistance and improve the opening and closing efficiency; its buoyancy box and ballast weight design ensure the axial stability of the opening and closing process; the use of floating gear meshing or pin gear drive can improve the opening and closing accuracy and has strong adaptability. In addition, the design of the track and the anti-hook device is combined to ensure the reliability of the opening and closing process. The ball joint and the rotating center column design are used at the center of rotation, which can adapt to the floating and swinging during the opening and closing process and ensure smooth operation.
