Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and in particular to a bottom protection structure for water utilization. Background Art

[0002] Water scouring is an important way to affect the evolution of rivers. It will cause a lot of soil and water loss, threaten the stability of the bank slope and damage the ecological environment. In the design of water conservancy projects, scouring protection is a key design point. The most serious part of water scouring is often the riverbed. For riverbeds with fast water flow and large water level changes, there are great design difficulties in designing the protective structure at the bottom of the riverbed. If a stronger protective structure is set for protection according to the most unfavorable water flow conditions, there will be a lot of safety surplus when running at low water level and low flow rate, resulting in a waste of investment; if a weaker protective structure is set for protection according to the water flow conditions of low water level and low flow rate, it will cause serious riverbed scouring when running at high water level and high flow rate, resulting in a lot of soil and water loss, and it will not play an effective protective role.

[0028] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0029] Please also read Figures 1 to 3The embodiment of the present application provides a bottom protection structure 100 for water utilization, including a base 10, a lifting device 20 and a plurality of baffles 30. The lifting device 20 is connected to the base 10. The plurality of baffles 30 are arranged in sequence along the water flow direction and form an undulating structure. The baffle 30 has two opposite ends along its own length direction. One end of the baffle 30 is movably connected to the base 10, and the other end of the baffle 30 is connected to the lifting device 20. The lifting device 20 is used to drive the baffle 30 to rise or fall to adjust the height of the baffle 30.

[0030] The bottom protection structure 100 for water utilization provided in the embodiment of the present application is configured by arranging a plurality of baffles 30 which are arranged in sequence and spaced apart in the direction of water flow to form an undulating structure, and the two ends of the baffles 30 along their own length direction are respectively connected to the base 10 and the lifting device 20, and the lifting device 20 is used to drive the baffles 30 to rise or fall to adjust the height of the baffles 30. In this way, by adjusting the height of the baffle 30, the speed of the water flow can be slowed down. Through the multi-level undulating structure with one high and one low, a multi-level blocking and sedimentation effect is formed, so that the silt flowing with the water flow is gradually settled between the two baffles 30 with different heights, thereby reducing the loss of silt in the water flow and improving the reliability of protection. At the same time, the height of the baffle 30 can be freely adjusted according to needs. Under low water level and low flow rate conditions, the baffle 30 is adjusted to be lowered through the lifting device 20 so that the height of the baffle 30 is adapted to the height of the flow of silt brought by the water flow, thereby not only blocking the flow of silt in the water flow, but also ensuring the normal circulation of the water flow, reducing investment waste; under high water level and high flow rate conditions, the baffle 30 is adjusted to be raised through the lifting device 20 so that the height of the baffle 30 is adapted to the height of the flow of silt brought by the water flow, thereby ensuring that the quicksand in the water flow can be intercepted by the baffle 30 to prevent soil and water loss. That is, under the conditions of different water levels and different flow rates, by adjusting the height of the baffle 30 to match the height of the flow of silt carried by the water flow, it is possible to effectively block the flow of silt in the water flow and prevent soil erosion, while ensuring the normal flow of water flow and reducing investment waste. It can be seen that the bottom protection structure 100 for water utilization provided by the present application can adapt to a larger range of water flow speed and water level changes, so as to reduce resource waste while ensuring the protection effect.

[0031] In some embodiments, the base 10 includes a supporting portion 11 and an intercepting portion 12 connected to the supporting portion 11, the intercepting portion 12 is arranged on the riverbed, the intercepting portion 12 is provided with a plurality of mounting grooves 121 arranged in sequence along the water flow direction, and the openings of the mounting grooves 121 face away from the riverbed, a plurality of baffles 30 are arranged one by one corresponding to the plurality of mounting grooves 121, and the baffles 30 can be movably connected to the mounting grooves 121 so that the height of the baffles 30 extending out of the mounting grooves 121 can be adjusted.

[0032] In this way, by setting the baffle 30 movably connected to the mounting groove 121, the height of the baffle 30 can be adjusted to adapt to different water levels and water flow speeds, and the verticality of the baffle 30 can be ensured to ensure the ability to block mud and sand, thereby avoiding the situation where the baffle 30 is unable to intercept mud and sand due to the baffle 30 being driven by the water flow to move offset.

[0033] Optionally, a slide rail 1210 is provided on the inner wall of the mounting groove 121, and sliders 31 are provided on both sides of the baffle 30, and the sliders 31 are slidably connected to the slide rail 1210. Thus, the baffle 30 can be slidably connected to the inner wall of the mounting groove 121, so as to reduce the friction force of the baffle 30 relative to the inner wall of the mounting groove 121, so as to reduce the resistance of the baffle 30 during the lifting movement, so that the lifting device 20 can adjust the height of the baffle 30 with less power, so as to achieve the effect of reducing energy consumption and saving labor.

[0034] Optionally, the depths of the plurality of installation grooves are consistent, and the lengths of the plurality of baffles 30 are different, so that the plurality of baffles 30 form an undulating structure along the water flow direction. In this way, when installing the baffles 30, the baffles 30 can be extended to the bottom of the installation grooves, so that the bottoms of the plurality of baffles 30 are kept at the same height in the initial state, which can help simplify the installation steps of the baffles 30 and reduce the difficulty of design and installation.

[0035] It is understandable that in other embodiments, the lengths of the plurality of baffles 30 may also be the same, and the bottoms of the plurality of baffles 30 may be adjusted to have different heights in the initial state to form an undulating structure.

[0036] Optionally, the support portion 11 may be any one of a support plate, a support column or a support block, which may be specifically configured according to actual needs and is not limited here.

[0037] In some embodiments, the lifting device 20 includes a fixed column 21, a winding portion 22 and a connecting member 23. The fixed column 21 is connected to the winding portion 22 and the intercepting portion 12 of the base 10. Both ends of the connecting member 23 are respectively connected to the winding portion 22 and the baffle 30. The winding portion 22 is used to drive the baffle 30 to move toward or away from the winding portion 22 through the connecting member 23.

[0038] In this way, there is a movable space between the winding portion 22 and the base 10 for the baffle 30 to move up and down. The baffle 30 is driven by the winding portion 22 and the connecting member 23 to move in a direction close to or away from the winding portion 22 to adjust the height of the baffle 30 extending out of the mounting groove 121, thereby realizing the height adjustment of the baffle 30. The structure for blocking mud and sand is formed by the fixed column 21, the winding portion 22, the connecting member 23, the baffle 30 and the intercepting portion 12, which is beneficial to improve the stability of the lifting and lowering movement of the baffle 30, reduce the influence of the water flow on the verticality of the baffle 30, and thus improve the reliability of the baffle 30 in intercepting mud and sand.

[0039] Optionally, the winding portion 22 includes a main body 221 and a rotating rod 222, the main body 221 is provided with a hollow portion and a lifting hole connected to the hollow portion, the rotating rod 222 is arranged in the hollow portion and is rotatable relative to the main body 221, and the end of the connecting member 23 away from the baffle 30 extends into the hollow portion through the lifting hole and is connected to the rotating rod 222.

[0040] In this way, by rotating the rotating rod 222 to adjust the number of turns of the connecting member 23 around the rotating rod 222, the distance of the baffle 30 relative to the winding portion 22 can be adjusted, thereby adjusting the height of the baffle 30.

[0041] Optionally, considering that multiple baffles 30 are arranged at intervals along the direction of water flow, when the axis of the rotating rod 222 is perpendicular to the direction of water flow, each connecting member 23 needs to be driven to wind through a rotating rod 222 respectively, that is, each baffle 30 needs to be correspondingly provided with a rotating rod 222. Based on this, the axis of the rotating rod 222 is parallel to the direction of water flow, so that the multiple baffles 30 can be distributed in a straight line along the direction of water flow and are respectively connected to the rotating rod 222, so as to help reduce the usage of the rotating rod 222, and by connecting the rotating rod 222 with multiple connecting members 23, the raising or lowering of multiple baffles 30 can be controlled at the same time, thereby improving the rationality of the design and the convenience of operation.

[0042] Optionally, a rotating wheel 223 is sleeved on the outer periphery of the rotating rod 222 , and the rotating wheel 223 is located in the hollow part. The connecting member 23 is arranged around the outer periphery of the rotating wheel 223 and is arranged corresponding to the lifting hole, so that the connecting member 23 is connected to the rotating rod 222 through the rotating wheel 223 .

[0043] In this way, the rotating wheel 223 is driven by the rotating rod 222 to rotate relative to the main body 221 to adjust the number of circles of the connecting member 23 around the outer circumference of the rotating wheel 223, thereby adjusting the height of the baffle 30, and the diameter of the outer circumference of the rotating rod 222 is increased by the rotating wheel 223, so that the diameter of each circle of the connecting member 23 increases, that is, the length of the connecting member 23 wound by each rotation of the rotating rod 222 becomes larger, so that the number of rotations of the rotating rod 222 can be reduced within the specified lifting height range, so as to facilitate the manual rotation of the rotating rod 222 by the operator, and avoid the operator's fatigue caused by the operator manually rotating the rotating rod 222 too many times. In addition, the setting of the rotating wheel 223 can also limit the displacement of the connecting member 23, so that the connecting member 23 is wound layer by layer along the outer circumference of the rotating wheel 223, and the connecting member 23 is prevented from moving along the axial direction of the rotating rod 222 during the winding process, thereby reducing the length loss of the connecting member 23 and improving the conversion efficiency of the rotary motion into the linear motion.

[0044] Optionally, there are multiple rotating wheels 223, multiple lifting holes and multiple connecting members 23, and the multiple rotating wheels 223, multiple lifting holes, multiple connecting members 23 correspond to the multiple baffles 30 one by one, thereby improving the flexibility of height adjustment of the baffles 30. By adjusting the multiple baffles 30 to have different heights in the initial state, it can be beneficial to intercept mud and sand. At the same time, when the rotating rod 222 rotates, the multiple baffles 30 are driven to rise and fall at the same time by the multiple rotating wheels 223 and the connecting members 23, so that one power source can simultaneously drive the multiple baffles 30 to rise and fall, so as to achieve the effect of reducing energy consumption and labor saving, and improve the efficiency of height adjustment of the baffles 30, so as to quickly switch the height of the baffles 30 when the water level and flow rate change rapidly, thereby helping to reduce soil erosion.

[0045] Optionally, the connecting member 23 may be any one of a steel wire rope, a synthetic fiber rope or a metal wire rope (such as a steel belt rope woven by steel belts), etc., and may be specifically configured according to actual needs and is not limited here.

[0046] Optionally, a fixing pin 24 is provided at one end of the connecting member 23 near the baffle 30, and the baffle 30 is provided with a threaded hole, and the fixing pin 24 is threadedly connected to the threaded hole. Thus, the connection between the connecting member 23 and the baffle 30 is detachable, and when one of the connecting member 23 and the fixing pin 24 is damaged, the damaged part can be replaced to continue to be used, so as to avoid the situation that the connecting member 23 and the fixing pin 24 need to be completely replaced when one of them is damaged due to the integral connection, thereby achieving the effect of reducing material costs.

[0047] Optionally, there can be multiple fixed columns 21, which are spaced apart in a direction perpendicular to the water flow, and the width of the baffle 30 is consistent with the width of the riverbed, thereby ensuring the normal passage of water flow and intercepting silt in the water flow to reduce the loss of silt.

[0048] In some embodiments, the baffle 30 is provided with a diverter component 32, which has a first end and a second end relative to each other along the water flow direction, and the second end is connected to the baffle 30. In the direction in which the baffle 30 is raised and lowered, the length of the diverter component 32 gradually increases along the water flow direction so that the length of the second end is greater than the length of the first end.

[0049] In this way, when the mud and sand at the bottom of the water flow follows the water flow to the diverter plate, the water flow is restricted by the diverter plate and the flow rate is slowed down, so that the mud and sand are deposited at the bottom of the water flow. When the water flow carries the mud and sand to hit the baffle 30, the water flow flows along the top of the diverter plate, and the mud and sand hit the baffle 30 along the bottom of the diverter plate, thereby staying between the multiple baffles 30.

[0050] Optionally, the diverter component 32 may be a triangular prism, and the first end is the tip of the triangular prism, so as to guide the sediment and water to flow along the top and bottom of the diverter component 32 respectively, thereby realizing the diversion of sediment and water, thereby reducing sediment loss.

[0051] In some embodiments, the base 10 also includes a reflux portion 13 disposed on the riverbed, and the reflux portion 13 is disposed at the front end of the interception portion 12 along the water flow direction (that is, the water flows through the reflux portion 13 first and then through the interception portion 12), and the reflux portion 13 is provided with a reflux pipe 131, and the two ends of the reflux pipe 131 are respectively provided with a first opening and a second opening with an opening facing away from the baffle 30, and the first opening and the second opening are spaced apart along the direction in which the baffle 30 is raised and lowered.

[0052] In this way, under the condition of low water level, when the water flow drives the sediment at the bottom to flow to the bottom protection structure 100, the water flow at the bottom drives the sediment to enter the first opening or the second opening, and flows out of the return pipe 131 through the other opening of the return pipe 131, so that the sediment in the water flows back again, so that the sediment is settled on the riverbed, and the water flow at the upper part flows through the return part 13 to the interception part 12, and the height of the baffle 30 is adjusted to intercept the sediment in the upper water flow. Thus, the multi-level protection function can be achieved, the protection effect can be improved, and the loss of sediment can be reduced.

[0053] Optionally, the return pipe 131 may be a U-shaped pipe, an arc-shaped pipe or a V-shaped pipe, etc., which may be specifically configured according to actual needs and is not limited here.

[0054] In some embodiments, the rotation of the rotating rod 222 can be manually controlled. The lifting device 20 also includes a handle 25 connected to one end of the rotating rod 222. The handle 25 is located on the periphery of the main body 221, so that the operator can manually rotate the rotating rod 222 to reduce the difficulty of operation.

[0055] It can be understood that in other embodiments, the rotation of the rotating rod 222 can also be controlled electrically, hydraulically or pneumatically.

[0056] Optionally, considering that the length direction of the rotating rod 222 is parallel to the direction of the water flow, the handle 25 is set at one end of the rotating rod 222. When the handle 25 is turned, the operator must take a boat or stand in the water flow. When the water flow speed is high, it is difficult for the operator to remain still in the water flow, resulting in manual adjustment of the rotation of the rotating rod 222. The safety of the operator is difficult to ensure. Based on this, the bottom protection structure 100 for water utilization also includes an adjustment platform 40, which is set on the riverbed and corresponds to the handle 25. The adjustment platform 40 is used to carry the operator.

[0057] In this way, when adjusting the height of the baffle 30, the operator can climb onto the adjusting platform 40 from the river bank, and turn the handle 25 on the adjusting platform 40 to drive the rotating rod 222 and the rotating wheel 223 to rotate, so that the operator can work on the riverbed, improve the operating convenience, and ensure the safety of the operator under high-velocity water flow conditions.

[0058] Optionally, considering that the reflux pipe 131 is located at the front end of the interception part 12, based on this, the regulating platform 40 can be located at the rear end of the base 10 along the water flow direction, that is, the water flows through the reflux part 13, the interception part 12 and the regulating platform 40 in sequence, so as to ensure the interception effect of the reflux part 13 and the interception part 12 on the sediment in the water flow and ensure that the water body can flow normally. In addition, it can also reduce the sediment deposition in front of the regulating platform 40 or on the regulating platform 40, which is conducive to improving the stability of the regulating platform 40 on the riverbed.

[0059] Optionally, the adjustment platform 40 includes a gravel layer 41, a foundation 42, a support 43 and a plane layer 44 from bottom to top, the gravel layer 41 and the foundation 42 are arranged in the riverbed, the support 43 is connected to the foundation 42 and the plane layer 44 and is located on the riverbed, and the plane layer 44 is used for operators to stand or squat. This can improve the structural stability of the adjustment platform 40, and reserve enough space for operators to stand or squat, thereby improving the safety of operators when working on the adjustment platform 40.

[0060] Optionally, there may be a plurality of pillars 43 , and the pillars 43 are arranged at intervals along a direction perpendicular to the water flow to improve the stability of the planar layer 44 .

[0061] Optionally, along a direction perpendicular to the water flow, both ends of the plane layer 44 are connected to the river banks on both sides, so that operators can climb onto the plane layer from the river banks to facilitate height adjustment of the baffle 30 .

[0062] Optionally, the width of the gravel layer 41 and the foundation 42 is consistent with the width of the riverbed, which can not only improve the stability of the adjustment platform 40 structure, but also protect the riverbed and reduce the degree of scouring of the riverbed by the water flowing through the return part 13 and the interception part 12.

[0063] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
