Description

Technical Field

[0001] The utility model belongs to the technical field of dam protection, and in particular relates to a reservoir dam protection structure. Background Art

[0002] Dam protection projects are generally embankment protection projects. In the river sections where renovation is being carried out, they are mainly used to control the lateral deformation of the reservoir riverbed, stabilize the boundary conditions of the water flow, and guide and control the water flow to a favorable direction.

[0003] The prior art discloses a safety protection structure applied to a reservoir dam (CN219260892U), comprising a dam body, one side of which is adhesively connected to a fixing block; the utility model mutually mounts and cooperates the protection plate and the block, so that the outer wall of the protrusion is clamped and connected with the inner wall of the square groove, and the rubber ring adhesively connected to the outer wall of the block is stably clamped with the inner wall of the square groove, so as to prevent the surface of the dam body from being directly eroded by rainwater and water sources in the reservoir; through the mutual mounting and cooperation of the vertical plate and the inclined plate, the outer wall of the pad on one side of the inclined plate is clamped with the inner wall of the ring groove, so as to reduce the impact force on the dam body and prevent the internal concrete structure from being damaged due to the impact force on the surface of the dam body.

[0004] After searching, it was found that the design of the horizontal plate of the device cannot guide the flow rate and direction of the water when in use. On the contrary, the smooth design is more likely to cause the impact of accelerated water flow, which makes the horizontal plate extremely susceptible to wear and tear, and thus requires frequent replacement. In addition, in rainy and snowy weather, the plate design of the horizontal plate cannot guide the discharge of water, which makes it easy for water to accumulate, thereby causing erosion of the reservoir dam.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0030] A reservoir dam protection structure, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a dam body 10, which is fixedly placed in the reservoir; a transverse plate 11, two transverse plates 11 are provided, the two transverse plates 11 are clamped with each other, and the transverse plates 11 are fixedly arranged on the inclined surface of the dam body 10 by bolts; a guide structure, the guide structure is fixedly arranged on the side of the transverse plate 11, the guide structure includes a guide plate 13 and a shock-reducing ladder plate 14, the guide plate 13 is located above the shock-reducing ladder plate 14, and the guide plate 13 and the shock-reducing ladder plate 14 are both fixedly arranged on the side of the transverse plate 11; a water discharge structure, the water discharge structure is movably arranged inside the transverse plate 11, the water discharge structure includes a water discharge port 15, a flow blocking block 20 and a flow discharge block 21, the water discharge port 15 is opened inside the transverse plate 11, and the flow blocking block 20 and the flow discharge block 21 are elastically arranged inside the transverse plate 11.

[0031] The working principle is as follows: a plurality of transverse plates 11 can be fixedly arranged on the inclined surface of the dam body 10 by bolts and nuts. When in use, the transverse plates 11 can protect the dam body 10. By setting a guide structure, the arc shape of the guide plate 13 is used to guide the flow direction of the water flow in a circuitous manner to help the water flow to flow back, and then the stepped shape of the shock-reducing ladder plate 14 is used to buffer and decelerate the fluctuating water flow, which can not only reduce the impact force of the water flow, but also reduce the flow rate of the water flow, thereby reducing the wear of the transverse plate. Damage can be avoided, and frequent replacement of the transverse plate can be avoided; by setting a water discharge structure, the impact force of water flow extrusion is used to squeeze the discharge block 21 or the blocking block 20, so that the blocking block 20 and the discharge block 21 are squeezed into the transverse plate 11 at the same time, so that the discharge block 21 and the blocking block 20 are lower than the position of the discharge port 15, and then the water flows through the discharge block 21 and the blocking block 20. The surface shape guides the water flow through the discharge port 15 to achieve the discharge effect, thereby achieving the guided discharge of the water flow to a certain extent, avoiding the erosion of the reservoir dam body by water accumulation.

[0032] like Figure 2 and Figure 3 As shown, the horizontal plate 11 is a square, and a notch 18 is respectively provided at the upper and lower ends of the horizontal plate 11, and a slot plate 17 is fixedly connected to the upper and lower ends of the horizontal plate 11, respectively. The slot plate 17 and the slot 18 are respectively located on the left and right sides of the horizontal plate 11, and the slot plate 17 is slidably connected to the slot 18. The insides of the slot plate 17 and the slot 18 are provided with threaded holes, and bolts are provided in the threaded holes. The slot plate 17 is fixed to the slot 18 by bolts; as shown Figure 2 and Figure 3 As shown, a clamping plate 19 is fixedly connected to one side of the transverse plate 11, and the clamping plate 19 is located between the two slots 18. A clamping port 16 is provided on one side of the transverse plate 11, and the clamping port 16 is located between the two slot plates 17. The clamping plate 19 clamps the clamping port 16. A plurality of through holes are provided inside the clamping port 16 and threads are provided in the through holes. Other bolts are provided through the threads. The clamping port 16 and the clamping plate 19 are fixedly connected by bolts.

[0033] The working principle is as follows. When in use, align the slot plate 17 with the slot 18, and align the clamping plate 19 with the clamping hole 16. By squeezing, the two horizontal plates 11 are engaged with each other, and then the bolts and nuts are fixed in the threaded holes to fix the two horizontal plates 11. Then, the bolts are penetrated into the holes to fix the dam body 10 and the two horizontal plates 11.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the side of the transverse plate 11 away from the dam body 10 is fixedly connected to the guide plate 13 and the shock-reducing ladder plate 14, and two shock-reducing ladder plates 14 are provided. The two shock-reducing ladder plates 14 are fixedly arranged at the middle position of one side of the transverse plate 11, and the guide plate 13 is located at the top of the shock-reducing ladder plate 14. The guide plate 13 is located at the common side adjacent to the groove plate 17 and the groove 18; Figure 2 and Figure 3 As shown, a blocking groove 22 and a discharge groove 23 are opened inside the transverse plate 11, and the blocking groove 22 and the discharge groove 23 are symmetrically arranged with the shock-reducing ladder plate 14 as the midpoint. The drain port 15 is located between the blocking groove 22 and the discharge groove 23, and the drain port 15 is arranged opposite to the shock-reducing ladder plate 14.

[0035] The working principle is as follows: the guide plate 13 is L-shaped; the inner side of the guide plate 13 near the shock-reducing ladder plate 14 is set to an arc-shaped structure, and an arc surface is set on the inner side; the side of the shock-reducing ladder plate 14 away from the cross plate 11 is set to a stepped shape; when the water flows through the shock-reducing ladder plate 14, it will also pass through the baffle block 20 and the discharge block 21 at the same time, and will be blocked by the stepped shape on the surface of the shock-reducing ladder plate 14, and will squeeze the baffle block 20 and the discharge block 21, so that part of the water flows through the drain port 15 to discharge, thereby achieving a certain degree of flow rate reduction; when the water flow is high tide and the impact force of the water flow is too large, the arc surface on the inner side of the guide plate 13 will slide along the inner arc surface to achieve a certain degree of reflux, thereby utilizing the reflux to reduce the impact force of the water flow.

[0036] like Figure 3 and Figure 4 As shown, a square ring groove is provided at the bottom of the choke groove 22, and the choke block 20 is composed of a wide wavy plate and a square ring. The square ring is slidably engaged in the square ring groove, and a resistance spring 24 is fixedly arranged between the wide wavy plate and the bottom surface of the choke groove 22. The choke block 20 is elastically connected to the choke groove 22 through the resistance spring 24; Figure 3 and Figure 5 As shown, a square ring groove is provided at the bottom of the discharge groove 23, and the discharge block 21 is composed of a narrow wavy plate and a square ring. The square ring is slidably engaged in the square ring groove, and a buffer spring 25 is fixedly arranged between the narrow wavy plate and the bottom surface of the discharge groove 23. The discharge block 21 is elastically connected to the discharge groove 23 through the buffer spring 25.

[0037] The working principle is as follows. When in use, the impact force of the water flow will squeeze the baffle block 20 and the discharge block 21. At this time, the baffle block 20 and the discharge block 21 will synchronously squeeze the resistance spring 24 and the buffer spring 25. Due to the cooperation of the resistance spring 24 and the buffer spring 25, the square ring and the square ring will synchronously slide in the square slide groove and the square ring groove under the action of elasticity. When the wide wavy plate and the narrow wavy plate of the baffle block 20 and the discharge block 21 are lower than the drain port 15, the water flow is buffered and discharged through the drain port 15. At the same time, the water flow will be hindered by the shape of the wide wavy plate and the narrow wavy plate when passing through them, slowing down a certain flow rate, thereby slowing down the erosion of the surface of the horizontal plate 11.
