Description

Technical Field

[0001] The utility model relates to the technical field of river maintenance engineering, in particular to a spur dike system capable of horizontal rotation. Background Technique

[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-raising 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-raising effect and the design value, and it is difficult to reach the most ideal state. In addition, the incoming flow of many rivers has obvious time differences. Therefore, the water-raising effect of a spur dike with a fixed structure on a certain incoming flow may be good, but once the incoming flow changes greatly, its water-raising effect is difficult to guarantee. It may raise the water level too much or may not raise the water level enough. 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 flow while ensuring the water-raising 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 and solved by those skilled in the art. Content 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 scheme:

[0006] A spur dike system capable of horizontal rotation, characterized in that it includes a dam body vertically arranged as a whole. One end of the dam body connected to the river bank is provided with a vertical rotating shaft along the vertical direction. The vertical rotating shaft is horizontally rotatably installed on a base platform arranged on the river bank, and the bottom of the river bed within the rotation range of the dam body is horizontally arranged; it also includes a dam body horizontal rotation control mechanism.

[0007] 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 horizontal rotation of the dam body 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 horizontally back to the riverbank to widen the river channel, accelerate the drainage of flood water, and at the same time avoid the erosion of the flood water on the dam body. This horizontal rotation type spur dike system is relatively suitable for implementation in river channels where the bottom of the river channel can be conveniently leveled into a horizontal shape. The utility model can better realize the regulation of water level elevation according to seasons and needs, and is more conducive to ensuring river channel navigation and river channel water diversion and irrigation operations.

[0008] Furthermore, the dam body horizontal rotation control mechanism includes two cables fixedly connected to both sides of the end of the dam body far from the rotating shaft, and also includes two horizontally arranged guide wheels respectively installed on the riverbanks on both the upstream and downstream sides of the dam body. At adjacent positions on the inner sides of the two guide wheels, there is a horizontal rotation control motor respectively. A winch is installed on the main shaft of the horizontal rotation control motor. The other ends of the two cables respectively bypass the corresponding guide wheels and are wound and connected to the winches of the corresponding horizontal rotation control motors.

[0009] In this way, by retracting and releasing the upper and lower two cables, the outer end of the dam body is pulled to achieve horizontal rotation, which has the advantages of simple structure, stable and reliable control. At the same time, this structure is convenient for controlling the rotation angle of the spur dike. When control is required, the spur dike can be positioned as an inclined flow deflecting type spur dike structure. Of course, in specific implementation, control can also be achieved through other dam body horizontal rotation control mechanisms. For example, a device capable of controlling the rotation angle of the rotating shaft can be directly installed at the vertical rotating shaft, such as setting a motor to drive the rotation of the rotating shaft through gear transmission, but the control stability of this structure is relatively poor.

[0010] Furthermore, the horizontal rotation control motor is a self-locking motor. It is convenient to realize automatic control to facilitate the positioning of the spur dike.

[0011] Furthermore, at one end of the dam body located on the riverbank, there is an extension section that extends beyond the position of the rotating shaft. The dam body horizontal rotation control mechanism also includes a plurality of retaining piles vertically arranged on the riverbank inside the rotating shaft. The retaining piles are arranged in an arc along the rotation path of the extension section of the dam body. A lifting base is provided at the lower end of the retaining pile to realize the lifting control of the retaining pile. When the retaining pile is lifted, the side surface on its downstream side can be in contact with the side surface on the upstream side of the extension section of the dam body that rotates to this position.

[0012] In this way, when the dam body rotates to a fixed position at a corresponding angle, the retaining pile at the corresponding position can be adjusted to rise, so that the side surface on the downstream side is in contact with the upstream side of the extension section of the dam body. The lever action is used to disperse the force and balance the moment of the dam body affected by the water flow impact, better protecting the rotating shaft of the dam body and the horizontal rotation control motor, and extending the service life of the equipment.

[0013] Furthermore, a row of rollers is provided at the bottom of the dam body. This makes the horizontal rotation of the dam body more convenient.

[0014] As an optimized option for the dam body structure, a rectangular slot hole is provided at the middle position of the dam body. The slot hole penetrates through the front and back, and a row of horizontally arranged turning pages is vertically arranged therein. The middle parts of the upper and lower ends of the turning pages are provided with turning page rotating shafts and are installed on the inner cavity walls on both sides of the upper and lower parts of the slot hole. A passive gear is fixedly arranged on each turning page rotating shaft, and each passive gear meshes with a rack that is horizontally slidably installed on the dam body. One end of the rack is provided with a turning page motor fixed to the dam body, and a driving gear meshing with the rack is installed on the main shaft of the turning page motor.

[0015] 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 in place, 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.

[0016] Furthermore, it further includes a control center. An angle sensor is installed on the vertical rotating shaft, and the angle sensor is connected to the control center. A turning page control module is arranged in the control center, and the turning page control module is connected to the turning page motor and is used to control each turning page to rotate and keep in the direction of the water flow during the rotation adjustment process of the dam body.

[0017] In this way, during the rotation process of the dam body, relying on the angle sensor to detect the rotation angle of the dam body and feedback to control each turning page to rotate accordingly, so that each turning page always keeps the width direction completely consistent with the water flow direction, enabling the water flow to pass through smoothly to the greatest extent, reducing the water flow resistance, and reducing the difficulty of controlling the rotation of the dam body.

[0018] 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, and a plurality of horizontally arranged insertion blocks are also arranged in the slot. The length of the insertion block matches the length of the slot, and it has a plurality of vertical insertion holes and is correspondingly inserted on the vertical columns.

[0019] In this way, a spur dike dam body structure that can realize submergence adjustment is obtained. The height of the dam body can be adjusted by increasing or decreasing the insertion blocks to realize the switching control between a submerged spur dike and a non-submerged spur dike, and the submergence depth can be adjusted as needed.

[0020] In summary, 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

[0022] Figure 2 It is a side view of the separate dam body part in the figure.

[0023] Figure 3 It is a schematic diagram of the dam body of another implementable structure in the horizontal rotation spur dike system.

[0024] Figure 4 It is Figure 3 a top view of the separate inserted block in Specific implementation mode

[0025] The following further elaborates on the present utility model in conjunction with the specific implementation mode.

[0026] Embodiment 1: A spur dike system capable of horizontal rotation. Refer to Figures 1-4 as shown, it includes a dam body 1 vertically arranged as a whole. One end of the dam body 1 connected to the riverbank is provided with a vertical rotating shaft 2 along the vertical direction. The vertical rotating shaft 2 is horizontally rotatably installed on the base platform arranged on the riverbank, and the bottom of the riverbed within the rotation range of the dam body 1 is horizontally arranged; it also includes a dam body horizontal rotation control mechanism.

[0027] In this way, when it is necessary to raise the water level in the dry season, the dam body can be controlled to rotate horizontally from the riverbank into the river channel to achieve water level raising; when it is not necessary to raise the water level in the flood season, the dam body can be controlled to rotate back to the riverbank to widen the river channel, accelerate flood discharge, and at the same time avoid the erosion of the flood on the dam body. This horizontal rotation spur dike system is relatively suitable for implementation and application in river channels where the bottom of the river channel can be conveniently leveled into a horizontal shape.

[0028] Among them, the dam body horizontal rotation control mechanism includes two cable wires 3 fixedly connected to both sides of the end of the dam body 1 far from the rotating shaft. It also includes two horizontally arranged guide wheels 4 respectively installed on the riverbank on both the upstream and downstream sides of the dam body 1. At the adjacent positions on the inner sides of the two guide wheels 4, there is a horizontal rotation control motor 5 each. A winch 6 is installed on the main shaft of the horizontal rotation control motor 5. The other ends of the two cable wires 3 respectively bypass the corresponding guide wheels 4 and are wound and connected to the winches 6 of the corresponding horizontal rotation control motors.

[0029] In this way, by retracting and releasing the upper and lower two cable wires, the outer end of the dam body is pulled to achieve horizontal rotation, which has the advantages of simple structure and stable and reliable control. At the same time, this structure is convenient for controlling the rotation angle of the spur dike. When control is required, the spur dike can be positioned as an inclined flow deflecting spur dike structure. Of course, in specific implementation, control can also be achieved through other dam body horizontal rotation control mechanisms. For example, a device capable of controlling the rotation degree of the rotating shaft can be directly installed at the vertical rotating shaft, such as setting a motor to drive the rotating shaft to rotate through gear transmission, but the control stability of this structure is relatively poor.

[0030] Among them, the horizontal rotation control motor 5 is a self-locking motor, which is convenient for realizing automatic control to facilitate the positioning of the spur dike.

[0031] Among them, one end of the dam body 1 located at the river bank also has an extension section 7 that extends beyond the position of the rotating shaft. The dam body horizontal rotation control mechanism also includes a plurality of retaining piles 8 vertically arranged on the inner side of the river bank of the rotating shaft. The retaining piles 8 are arranged in an arc along the rotation path of the extension section 7 of the dam body. The lower end of the retaining pile 8 is provided with a lifting base to realize the lifting control of the retaining pile. When the retaining pile 8 rises, the side surface on its downstream side can be attached to the upstream side surface of the extension section of the dam body that rotates to this position.

[0032] In this way, when the dam body rotates to a fixed position at a corresponding angle, the retaining pile at the corresponding position can be adjusted to rise, so that the downstream side surface is attached to the upstream side of the dam body extension section, and the lever action is used to disperse the force and balance the moment of the dam body affected by the water flow impact, better protecting the dam body rotating shaft and the horizontal rotation control motor, and extending the service life of the equipment.

[0033] Among them, a row of rollers 9 are arranged at the bottom of the dam body 1, which makes it more convenient for the horizontal rotation of the dam body.

[0034] As an optimized choice of the dam body structure, refer to Figure 2 , a rectangular slot is arranged at the middle position of the dam body 1. The slot penetrates through the front and back, and a row of horizontally arranged turning blades 10 are vertically arranged therein. The middle parts of the upper and lower ends of the turning blades 10 are provided with turning blade rotating shafts and are installed on the inner cavity walls on the upper and lower sides of the slot. A passive gear 11 is also fixedly arranged on each turning blade rotating shaft. Each passive gear 11 meshes with a rack 12 that is horizontally slidably installed on the dam body. One end of the rack 12 is provided with a turning blade motor 13 fixed to the dam body. An active gear 14 is installed on the main shaft of the turning blade motor 13 and meshes with the rack 12.

[0035] In this way, a spur dike dam body structure that is convenient for realizing water permeability adjustment is obtained. When the dam body rotates, the turning blades can be controlled to rotate and open to allow water to pass through, 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 place, when needed, the turning blades can also be controlled to rotate to allow water to pass through, realizing the switching control between an impermeable spur dike and a permeable spur dike.

[0036] Among them, it also includes a control center (not shown in the figure). An angle sensor (not shown in the figure) is installed on the vertical rotating shaft. The angle sensor is connected to the control center. A turning blade control module is arranged in the control center. The turning blade control module is connected to the turning blade motor and is used to control each turning blade to rotate and keep in the direction of the water flow during the rotation adjustment process of the dam body.

[0037] In this way, during the rotation of the dam body, the rotation angle of the dam body is detected by the angle sensor, and the rotation of each turning leaf is feedback-controlled to follow, so that each turning leaf always keeps the width direction and the water flow direction completely consistent, enabling the water flow to pass smoothly to the greatest extent, reducing the water flow resistance, and reducing the difficulty of controlling the rotation of the dam body.

[0038] As another implementable structure of the dam body structure, refer to Figure 3 and Figure 4 , a rectangular slot is provided upward at the middle position of the dam body 1. A plurality of vertical columns 15 are arranged at intervals in the slot, and a plurality of horizontally arranged insertion blocks 16 are also arranged in the slot 15. The length of the insertion block 16 matches the length of the slot, and it has a plurality of vertical insertion holes and is correspondingly inserted on the vertical columns 15.

[0039] 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 insertion blocks, realizing the conversion control between the submersible spur dike and the non-submersible spur dike, and the submersible depth can be adjusted as needed.
