Description

Technical Field

[0001] The utility model relates to the technical field of river maintenance engineering, in particular to a spur dike system that can rotate vertically. Background Art

[0002] A spur dike, also known as a "flow deflecting dam", is a river engineering structure with one end connected to the bank and the other end extending into the river. Because its planar shape resembles the Chinese character "ding" (T-shaped), it is called a spur dike. Since the spur dike has the function of raising the water level, it is widely used in waterway regulation and water diversion irrigation projects. Existing spur dikes are usually of fixed structures, so once they are built, their water retaining effect on the river is determined. Due to the extremely complex terrain of the real river and the constantly changing river water conditions, it is impossible for designers to fully consider all factors affecting the implementation effect of the project. Therefore, after the spur dike is built, there will be an error between its actual water retaining effect and the design value, and it is difficult to reach the most ideal state. In addition, the incoming water flow of many rivers has obvious time differences. Therefore, the water retaining effect of a spur dike with a fixed structure may be good for a certain incoming water flow, but once the incoming water flow changes greatly, its water retaining effect is difficult to guarantee. It may retain too much water or not enough water. In other words, a spur dike with a fixed structure does not have flexible adjustability and multi-adaptability. It can neither eliminate the design error through later structural modification nor adapt to the change of the incoming water flow while ensuring the water retaining effect. In addition, during the flood period of the river, the existence of a spur dike with a fixed structure may cause the water flow to be more rapid and dangerous, the water level to be too high, and flood disasters to occur. Moreover, during the flood period, the water flow is rapid and has a large impact force, which easily causes the spur dike with a fixed structure to be scoured and damaged, reducing its service life.

[0003] In view of this, how to make better use of the spur dike and make it more convenient to adjust the water level for navigation and water diversion irrigation has become a problem to be considered by those skilled in the art. Summary of the Utility Model

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide a new type of spur dike system that can better realize water level adjustment control to facilitate river navigation and water diversion irrigation.

[0005] To solve the above technical problem, the utility model adopts the following technical solutions:

[0006] A spur dike system that can rotate vertically, characterized in that it includes a dam body vertically arranged as a whole. At the upper end of the side where the dam body is connected to the river bank, there is a turning handle extending horizontally outwards. The turning handle is vertically rotatably installed on a base platform arranged on the river bank through a horizontal rotating shaft; it also includes a dam body vertical rotation control mechanism.

[0007] In this way, when it is necessary to raise the water level during the dry season, the vertical rotation of the dam body around the horizontal axis can be controlled so that it rotates from the riverbank into the river channel to achieve the raising of the water level. When it is not necessary to raise the water level during the flood season, the dam body can be controlled to rotate upward back to the riverbank to widen the river channel, accelerate the discharge of flood water, and at the same time avoid the erosion of the flood on the dam body. This vertical rotation type spur dike system is more suitable for implementation in river channels where it is inconvenient to level the bottom of the river channel to a horizontal shape because it does not require horizontal rotation.

[0008] Furthermore, the vertical rotation control mechanism of the dam body includes a tie rod arranged along the length direction of the dam body. One end of the tie rod is hinged to a connecting seat protruding upward at the upper part on the side of the dam body away from the riverbank, and the other end of the tie rod is hinged to a horizontally arranged connecting rod on the riverbank. The connecting rod is installed in a horizontally arranged limiting hole of a limiting support on the riverbank. The limiting support is used to limit that the connecting rod can only slide along the length direction of the dam body. A transmission tooth is arranged along the length direction on one side surface of the connecting rod. It also includes a vertical rotation control motor, and a control gear is installed on the main shaft of the vertical rotation control motor and meshes with the transmission tooth at the end of the connecting rod away from the dam body.

[0009] In this way, by driving the control gear and the transmission tooth to mesh and drive through the vertical rotation control motor, the connecting rod moves horizontally, and acts on the dam body through the tie rod to drive the dam body to flip, realizing the control of raising and lowering the dam body. The structure is simple, the control is convenient, and the lever principle is utilized. By increasing the force arm and reducing the force, the control process is more labor-saving and stable. Of course, in specific implementation, the control can also be realized through other vertical rotation control mechanisms of the dam body. For example, a device capable of controlling the rotation angle of the rotating shaft can be directly installed at the horizontal rotating shaft. For example, a motor is set to drive the rotating shaft to rotate through gear transmission. This structure is simpler, but the control stability is relatively poor.

[0010] Furthermore, the length of the tie rod is greater than the length of the dam body, so that the hinged position of the connecting rod and the tie rod is located on the riverbank inside the rotating handle of the dam body. This better increases the force arm and reduces the force, further improving the control stability.

[0011] Furthermore, the transmission tooth is located on one side surface of the upper end of the connecting rod and is set lower than the upper end surface.

[0012] This better protects the transmission tooth from contacting the limiting block of the limiting support.

[0013] Furthermore, rollers are arranged on the upper and lower side surfaces of the inner cavity of the limiting hole of the limiting support to contact the surface of the connecting rod.

[0014] In this way, the contact surface between the connecting rod and the limiting support is a rolling fit, which is more convenient for the sliding of the connecting rod.

[0015] Further, the length of the connecting rod is greater than the sum of the lengths of the dam body and the tie rod, and the distance from the limiting support to the horizontal rotating shaft is equal to or greater than the sum of the lengths of the dam body and the tie rod.

[0016] In this way, the dam body can be pulled and flipped 180 degrees by the tie rod, so that the whole is pulled down to the river bank, better maintaining stability.

[0017] Further, there are two limiting supports, and the vertical rotation control motor and its control gear are located between the two limiting supports. This can better ensure stability.

[0018] Further, the vertical rotation control motor is a self-locking motor. It is convenient to realize automatic control for the positioning of the spur dike.

[0019] Further, a plurality of retaining piles are vertically and fixedly arranged adjacent to the downstream side of the dam body. The retaining piles are arranged at intervals along the length direction of the dam body, and the upstream side surface of the retaining piles is in contact with the downstream side surface of the dam body.

[0020] In this way, the retaining piles can support and resist the impact force of the river water on the dam body, ensuring the stable and reliable structure of the dam body itself and the stable and reliable process of controlling the rotation of the dam body.

[0021] Further, some of the retaining piles are arranged within the rotation range of the dam body on the river bank, and the height of the upper end surface of each retaining pile is set as an arc along the rotation path of the end far from the river bank when the dam body rotates.

[0022] In this way, the retaining piles can better bear the force during the entire rotation path of the dam body, improving the stability of the rotation control process.

[0023] As an optimized choice for the dam body structure, a rectangular slot is provided at the middle position of the dam body. The slot penetrates through the front and back, and a row of horizontally arranged rotating blades is vertically arranged therein. Rotating shafts are provided in the middle of the upper and lower ends of the rotating blades and are installed on the inner cavity walls on both sides of the upper and lower parts of the slot. A passive gear is fixedly arranged on each rotating shaft, and each passive gear meshes with a rack that can be horizontally slidably installed on the dam body. One end of the rack is provided with a rotating blade motor fixed to the dam body, and an active gear meshing with the rack is installed on the main shaft of the rotating blade motor.

[0024] In this way, a spur dike dam body structure convenient for realizing water permeability adjustment is obtained. When the dam body rotates, the rotating blades can be controlled to rotate and open for water permeability, reducing the water flow resistance and facilitating the smooth realization of the rotation adjustment control of the dam body. At the same time, after the dam body rotates to the position, when needed, the rotating blades can also be controlled to rotate for water permeability to realize the switching control between an impermeable spur dike and a permeable spur dike.

[0025] Further, a control center is also included, and the control center is connected to each motor. This is more convenient for realizing control.

[0026] As another optimized option for the dam body structure, a rectangular slot is provided upward at the middle position of the dam body. A plurality of vertical columns are arranged at intervals in the slot. A plurality of horizontally arranged inserts are also provided in the slot. The length of the insert matches the length of the slot, and the insert has a plurality of vertical jacks and is correspondingly inserted on the vertical columns. A screw hole is also provided on each column at the position corresponding to the upper surface after each insert is installed. The screw hole is used to install a bolt to fix the installed insert.

[0027] In this way, a spur dike dam body structure that can achieve submersible adjustment is obtained. The height of the dam body can be adjusted by increasing or decreasing the inserts, realizing the conversion control between the submersible spur dike and the non-submersible spur dike, and the submersible depth can be adjusted according to needs.

[0028] To sum up, the utility model has the advantages of being able to better realize water level adjustment control to facilitate river navigation and water diversion irrigation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following further details the utility model in conjunction with the specific embodiments.

[0036] Embodiment 1: Referring to Figure 1-6 shown, a spur dike system that can rotate vertically, characterized in that it includes a dam body 21 that is vertically arranged as a whole. The upper end of the side where the dam body 21 is connected to the river bank has a horizontally extending rotating handle 22. The rotating handle 22 is vertically rotatably installed on a base platform arranged on the river bank through a horizontal rotating shaft 23; it also includes a dam body vertical rotation control mechanism.

[0037] In this way, when it is necessary to raise the water level during the dry season, the water level can be raised by controlling the vertical rotation of the dam body around the horizontal rotation axis so that it rotates from the riverbank into the river channel. When it is not necessary to raise the water level during the flood season, the dam body can be controlled to rotate upward back to the riverbank to widen the river channel, accelerate the discharge of flood water, and at the same time avoid the erosion of the flood on the dam body. This vertical rotation type spur dike system is more suitable for implementation in river channels where the bottom of the river channel is inconvenient to be leveled into a horizontal shape because it does not require horizontal rotation.

[0038] Among them, the dam body vertical rotation control mechanism includes a pull rod 24 arranged along the length direction of the dam body. One end of the pull rod 24 is hinged to a connecting seat 25 protruding upward at the upper part on the side of the dam body away from the riverbank. The other end of the pull rod 24 is hinged to a horizontally arranged connecting rod 26 on the riverbank. The connecting rod 26 is installed in a horizontally arranged limit hole of a limit support 27 on the riverbank. The limit support 27 is used to limit that the connecting rod can only slide along the length direction of the dam body. A transmission tooth 28 is arranged along the length direction on one surface of the connecting rod 26. It also includes a vertical rotation control motor 29. A control gear 30 is installed on the main shaft of the vertical rotation control motor and meshes with the transmission tooth 28 at the end of the connecting rod away from the dam body.

[0039] In this way, by driving the control gear and the transmission tooth to mesh and drive through the vertical rotation control motor, the connecting rod moves horizontally, and acts on the dam body through the pull rod to drive the dam body to flip, realizing the control of lifting and lowering the dam body. The structure is simple, the control is convenient, and the lever principle is utilized to reduce the force by increasing the force arm, making the control process more labor-saving and stable. Of course, in specific implementation, the control can also be realized through other dam body vertical rotation control mechanisms. For example, a device capable of controlling the rotation angle of the rotation shaft can be directly installed at the horizontal rotation shaft. For example, a motor is set to drive the rotation shaft to rotate through gear transmission. This structure is simpler, but the control stability is relatively poor.

[0040] Among them, the length of the pull rod 24 is greater than the length of the dam body 21, so that the hinged position of the connecting rod 26 and the pull rod is located on the riverbank inside the handle of the dam body 21. In this way, the force arm is better increased to reduce the force, and the control stability is further improved.

[0041] Among them, the transmission tooth 28 is located on one surface of the upper end of the connecting rod 26 and is arranged lower than the upper end surface.

[0042] In this way, it better protects the transmission tooth from contacting the limit block of the limit support.

[0043] Among them, roller wheels are arranged on the upper and lower side surfaces of the inner cavity of the limit hole of the limit support 27 to contact the surface of the connecting rod (not shown in the figure).

[0044] In this way, the contact surface between the connecting rod 26 and the limit support 27 is a rolling fit, which is more convenient for the sliding of the connecting rod.

[0045] Among them, the length of the connecting rod 26 is greater than the sum of the lengths of the dam body 21 and the tie rod 24, and the distance from the limit support 27 to the horizontal rotating shaft 23 is equal to or greater than the sum of the lengths of the dam body and the tie rod.

[0046] In this way, the dam body can be pulled and flipped 180 degrees by the tie rod, so that the whole dam body is pulled down to the river bank, better maintaining stability.

[0047] Among them, there are two limit supports 27, and the vertical rotation control motor and its control gear are located between the two limit supports. This can better ensure stability.

[0048] Among them, the vertical rotation control motor 30 is a self-locking motor. It is convenient to realize automatic control for the positioning of the spur dike.

[0049] Among them, a plurality of retaining piles 31 are vertically and fixedly arranged adjacent to the downstream side of the dam body. The retaining piles 31 are arranged at intervals along the length direction of the dam body, and the upstream side surface of the retaining piles 31 is in contact with the downstream side surface of the dam body 21.

[0050] In this way, the retaining piles can support and resist the impact force of the river water on the dam body, ensuring the stable and reliable structure of the dam body itself and the stable and reliable process of controlling the rotation of the dam body.

[0051] Among them, some retaining piles are arranged within the rotation range of the dam body on the river bank, and the upper end surface heights of the retaining piles are set in an arc along the rotation path of the end away from the river bank when the dam body rotates.

[0052] In this way, the retaining piles can better bear the force during the entire rotation path of the dam body, improving the stability of the rotation process control.

[0053] As an optimized choice for the dam body structure, refer to Figure 4 , a rectangular slot is provided at the middle position of the dam body 21. The slot penetrates through the front and back, and a row of horizontally arranged turning pages 32 are vertically arranged therein. The middle parts of the upper and lower ends of the turning pages 32 are provided with turning page rotating shafts and are installed on the inner cavity walls on the upper and lower sides of the slot. A passive gear 33 is also fixedly provided on each turning page rotating shaft, and each passive gear 33 is engaged with a rack 34 that is horizontally slidably installed on the dam body. One end of the rack 34 is provided with a turning page motor 35 fixed to the dam body, and a driving gear 36 is installed on the main shaft of the turning page motor 35 and is engaged with the rack 34.

[0054] In this way, a spur dike dam body structure that is convenient to realize water permeability adjustment is obtained. When the dam body rotates, the turning pages can be controlled to rotate and open for water permeability, reducing the water flow resistance and facilitating the smooth realization of the rotation adjustment control of the dam body. At the same time, after the dam body rotates to the position, when needed, the turning pages can also be controlled to rotate for water permeability to realize the switching control between an impermeable spur dike and a permeable spur dike.

[0055] Among them, it also includes a control center, and the control center is connected to each motor. This makes it more convenient to achieve control.

[0056] As another optimized option for the dam body structure, refer to Figure 5 and Figure 6 , a rectangular slot is provided upward at the middle position of the dam body 21. A plurality of vertical columns 37 are arranged at intervals in the slot. A plurality of horizontally arranged inserts 38 are also provided in the slot. The length of the insert 38 matches the length of the slot and it has a plurality of vertical jacks and is correspondingly inserted on the vertical columns 37. Screw holes are also provided at the upper surface positions corresponding to each insert after installation on each column. The screw holes are used to install bolts 39 to fix the installed inserts 38.

[0057] In this way, a spur dike dam body structure that can achieve submersible adjustment is obtained. The height of the dam body can be adjusted by increasing or decreasing the inserts, so as to realize the conversion control between the submersible spur dike and the non-submersible spur dike, and the submersible depth can be adjusted as needed.
