Description

Technical Field

[0001] This invention relates to the field of barrier dam technology, and in particular to a combined stabilized debris flow barrier dam. Background Technology

[0002] Among related technologies, Chinese invention patent CN103088791B discloses a debris flow retaining dam combining energy dissipation, drainage, and interception. The dam includes a foundation and a main body built upon the foundation. The main body comprises several piers spaced at regular intervals, with horizontal grids between each pair of piers. The piers extend upstream from the grids, and the grids are 0.5-1.0m high above ground. The grids are hollow, forming drainage holes with transverse and longitudinal beams for support. Compared to existing technologies, this invention utilizes piers to support the dam and intercept coarse particles; it uses drainage holes to drain water from debris flows passing over the dam, disrupting the debris flow structure and preventing structural blockage; and it uses horizontal grids for energy dissipation and drainage, increasing the dam's flow capacity, making the entire retaining dam less prone to blockage, increasing its ability to resist subsequent debris flows after a single flow, while ensuring downstream safety.

[0003] However, the horizontal grids of the aforementioned debris flow retaining dams are mostly integrally molded, which makes it difficult to flexibly adjust the height of the horizontal grids according to the required retaining height of the dam body design, thus affecting the effectiveness of the retaining dam. Summary of the Invention

[0004] To address the technical problems mentioned in the background section, this invention provides a combined stabilized debris flow barrier dam.

[0006] The connecting device includes a first cylinder. A docking groove is provided on the side of the horizontal grid near the support. The first cylinder is vertically arranged in the docking groove. A locking rod is threaded into the bottom of the first cylinder. A limiting block is sleeved and fixed on the outside of the locking rod. One side of the limiting block is slidably locked onto the groove wall of the docking groove. A locking hole is provided at the top of the first cylinder to engage with the locking rod.

[0007] As a further improvement to the above solution, a cross arm is provided in the docking groove, and the first cylinder is rotatably inserted into the cross arm.

The second cylinder is parallel to the horizontal grid and a docking rod is movably inserted inside it. A docking hole is opened on the side wall of the support.

[0009] When the limiting block moves downward, the docking rod is driven by the limiting block to be inserted into the docking hole along the second cylinder.

[0010] As a further improvement to the above solution, a second connecting rod parallel to the support is movably provided at the end of the connecting rod away from the adjacent support. A first connecting rod is movably inserted on the second connecting rod, and one end of the first connecting rod is movably inserted on the other side of the limiting block.

[0011] As a further improvement to the above solution, the first connecting rod is in the form of an L-shape. The first connecting rod has a horizontal section and a vertical section. The horizontal section is pinned to the limiting block, and the vertical section is pinned to the second connecting rod. A synchronous shaft is fixedly inserted at the junction of the horizontal section and the vertical section. The synchronous shaft is rotatably inserted into the groove wall of the docking groove.

[0013] As a further improvement to the above solution, an arc-shaped track groove is provided on the inner side wall of the second cylinder. A track block that slides and engages with the track groove is provided on the outer side of the end of the docking rod away from the docking hole. A third connecting rod is coaxially inserted on the end of the docking rod away from the support. One end of the third connecting rod is fixed to the second connecting rod. An external thread is provided on the outer side of the docking rod near the docking hole. An internal thread that matches the external thread is provided on the inner side wall of the docking hole.

[0014] As a further improvement to the above solution, a receiving groove is radially provided on the docking rod, and a retaining bead that can protrude from the groove is elastically provided in the receiving groove. A retaining groove that engages with the retaining bead is provided on the inner side wall of the docking hole.

[0015] As a further improvement to the above solution, a first support plate is fixed in the receiving groove, and a fourth connecting rod is slidably inserted into the first support plate. One end of the fourth connecting rod is fixed to the retaining bead, and a first spring is sleeved on the outside of the fourth connecting rod. The two ends of the first spring are respectively fixed to the outer wall of the first support plate and the outer wall of the retaining bead. When the first spring does not deform, the retaining bead protrudes from the outside of the receiving groove.

[0016] As a further improvement to the above solution, the foundation of the dam body is also reserved with locking holes for engaging with the locking rod.

[0034] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] Example 1

[0036] Please combine Figures 1 to 9The combined stabilized debris flow barrier dam includes a dam body main body set on the dam body foundation 1. The dam body main body includes several piers 2. Horizontal grids 3 are stacked vertically along the height direction of two adjacent piers 2. The horizontal grids 3 are locked and fixed by a connecting device so that the appropriate number of horizontal grids 3 can be selected and stacked according to the dam design requirements, so as to flexibly set the barrier height of the dam body main body.

[0037] The connecting device includes a first cylindrical body 5. A docking groove 4 is provided on the side of the horizontal grid 3 adjacent to the support pier 2. The first cylindrical body 5 is vertically installed in the docking groove 4. A locking rod 6 is threaded into the bottom of the first cylindrical body 5. A limiting block 7 is sleeved and fixed on the outside of the locking rod 6. One side of the limiting block 7 is slidably locked onto the groove wall of the docking groove 4. A locking hole 8 is provided at the top of the first cylindrical body 5 to engage with the locking rod 6. A locking hole 8 should also be reserved on the dam foundation 1.

[0038] In this embodiment, the docking groove 4 has a groove (not shown) parallel to the support 2 on its groove wall. The limiting block 7 is slidably engaged in the groove and can move relative to it along the groove. A cross arm is provided in the docking groove 4, and the first cylinder 5 is rotatably inserted into the cross arm.

[0039] In other words, when it is necessary to assemble two horizontal grids 3 stacked on top of each other, firstly, by rotating the first cylinder 5 on the lower horizontal grid 3, the locking rod 6 is inserted into the locking hole 8 on the foundation 1 of the dam body. Then, by rotating the first cylinder 5 on the upper horizontal grid 3, the locking rod 6 on the upper side is inserted into the locking hole 8 at the top of the lower first cylinder 5. This can achieve a stable assembly and fixation between the stacked horizontal grids 3, which is safe and convenient.

[0040] In this embodiment, in order to not only achieve rapid assembly and fixing between stacked horizontal grid fences 3, but also to simultaneously achieve installation and fixing between the horizontal grid fence 3 and its adjacent support piers 2, the specific details are as follows:

[0041] The connecting device also includes a second cylinder 15, which is fixed in the docking groove 4 on the side near the adjacent support 2. The second cylinder 15 is parallel to the horizontal grid 3 and a docking rod 16 is inserted inside. A docking hole 17 is opened on the side wall of the support 2.

[0042] When the limiting block 7 moves down, the connecting rod 16 is driven by the limiting block 7 to be inserted into the connecting hole 17 along the second cylinder 15, thereby completing the initial fixation between the horizontal grid 3 and the support 2.

[0043] A second connecting rod 12 parallel to the support 2 is movably provided at the end of the connecting rod 16 away from the adjacent support 2. A first connecting rod 9 is movably inserted on the second connecting rod 12. One end of the first connecting rod 9 is movably inserted on the other side of the limiting block 7.

[0044] Furthermore, the first connecting rod 9 has an overall L-shaped structure, and has a horizontal section (not shown) and a vertical section (not shown). The horizontal section is pinned to the limiting block 7, and the vertical section is pinned to the second connecting rod 12. A synchronous shaft 31 is fixedly inserted at the junction of the horizontal and vertical sections. The synchronous shaft 31 is rotatably inserted into the groove wall of the docking groove 4, so the first connecting rod 9 can rotate within the docking groove 4 following the synchronous shaft 31.

[0045] Specifically, a first pin hole 11 parallel to the horizontal section and shaped like a racetrack is provided on the horizontal section. A first pin 10 is inserted into the other side of the limiting block 7, and the first pin 10 is slidably engaged in the first pin hole 11. A second pin 13 is inserted into the vertical section, and a second pin hole 14 parallel to the vertical section and shaped like a racetrack is provided on the second connecting rod 12. The second pin 13 is slidably engaged in the second pin hole 14.

[0046] The inner wall of the second cylinder 15 has an arc-shaped track groove 20. The outer side of the connecting rod 16 away from the connecting hole 17 is provided with a track block 19 that slides and engages with the track groove 20. The end of the connecting rod 16 away from the support 2 is coaxially rotatably inserted with a third connecting rod 18. One end of the third connecting rod 18 is fixed to the second connecting rod 12. The outer side of the connecting rod 16 near the connecting hole 17 is provided with external threads, and the inner wall of the connecting hole 17 is provided with internal threads that match the external threads.

[0047] Since the track groove 20 in this embodiment has an arc-shaped structure, when the docking rod 16 is pushed by the third connecting rod 18 and the second connecting rod 12, the track block 19 on it will be continuously squeezed by the inner wall of the track groove 20, forcing the docking rod 16 to rotate relative to the third connecting rod 18. At this time, the docking rod 16 is in a state of rotating forward toward the docking hole 17, and under the cooperation of the internal and external threads, the docking rod 16 is locked and fixed in the docking hole 17, so as to realize the installation and fixation between the horizontal grid 3 and the support 2 simultaneously while installing and fixing between the stacked horizontal grid 3, which is stable and reliable.

[0048] To further enhance the stability of the connection between the connecting rod 16 and the connecting hole 17, the connecting rod 16 in this embodiment is provided with a radially opening receiving groove 21. A retaining bead 23 that can protrude from the groove opening is elastically provided in the receiving groove 21. A retaining groove 24 that engages with the retaining bead 23 is provided on the inner side wall of the connecting hole 17.

[0049] A first support plate 22 is fixed in the receiving groove 21. A fourth connecting rod 25 is slidably inserted into the first support plate 22. One end of the fourth connecting rod 25 is fixed to the retaining bead 23, and a first spring is sleeved on the outside of the fourth connecting rod 25. The two ends of the first spring are respectively fixed to the outer wall of the first support plate 22 and the outer wall of the retaining bead 23. When the first spring does not deform, the retaining bead 23 protrudes from the outside of the receiving groove 21.

[0050] As can be seen from the above, when the docking rod 16 is screwed into the docking hole 17, the locking ball 23 will be aligned with the locking groove 24. At this time, the spring force of the first spring is released, pushing the locking ball 23 into the locking groove 24, further locking and fixing the docking rod 16 and the docking hole 17.

[0051] Example 2

[0052] Please combine Figures 1 to 9 This embodiment is an improvement on embodiment 1. To prevent the retaining bead 23 from protruding from the opening of the receiving groove 21 and pressing against the inner wall of the docking hole 17 when the retaining bead 23 has not been moved to the retaining groove 24, thereby causing interference resistance when the docking rod 16 is screwed into the docking hole 17, this embodiment makes the following improvements based on embodiment 1:

[0053] A groove 27, axially connected to a receiving groove 21, is provided inside the connecting rod 16. A slider 29 is slidably connected within the groove 27. A second support plate 28 is fixed within the groove 27, and the second support plate 28 is located on the side of the slider 29 closest to the receiving groove 21. A fifth connecting rod 30 is slidably inserted onto the second support plate 28. One end of the fifth connecting rod 30 is fixed to the side wall of the slider 29, and a second spring is sleeved on its outer side. The two ends of the second spring are respectively fixed to the side wall of the slider 29 and the side wall of the second support plate 28. The elastic force of the first spring is less than that of the second spring.

[0054] A pressure-bearing groove 26 is provided on the outer wall of the radial end of the fourth connecting rod 25. The pressure-bearing groove 26 is an inclined groove that is inclined in the axial direction of the fourth connecting rod 25. The end of the fifth connecting rod 30 near the receiving groove 21 contacts the pressure-bearing groove 26 and then slides and squeezes to engage. A spool 32 is sleeved and fixed on the synchronous shaft 31. A tensioned traction rope is wound on the spool 32. The free end of the traction rope passes into the connecting rod 16 and is bolted and fixed to the corresponding side wall of the slider 29.

[0055] In this embodiment, when the limiting block 7 does not move down, the end of the fifth link 30 is inserted into the pressure groove 26 of the fourth link 25 (the second spring is in a non-deformed state), and at this time the retaining ball 23 is completely retracted into the receiving groove 21 (the first spring is in a compressed state).

[0056] When the limiting block 7 moves down, it drives the docking rod 16 to rotate and advance towards the docking hole 17 via the first connecting rod 9, the second connecting rod 12, and the third connecting rod 18, so that the docking rod 16 is screwed into the docking hole 17 to complete the fixation. During this period, the first connecting rod 9 will drive the synchronous shaft 31 to deflect around the inner wall of the docking groove 4, which will cause the pulley 32 to rotate and wind up the traction rope, so as to pull the slider 29 and the fifth connecting rod 30 to move away from the receiving groove 21 in the sliding groove 27 (the second spring is compressed). When the docking rod 16 is fully screwed into the docking hole 17, the end of the fifth connecting rod 30 just disengages from the pressure groove 26. At this time, under the action of the release of the first spring force, it will push the retaining ball 23 to be inserted into the retaining groove 24, so that the screwed docking rod 16 and the docking hole 17 remain stable, thereby making the connection between the horizontal grid 3 and the support 2 more stable.

[0057] When disassembly is required, the first connecting rod 9 drives the synchronous shaft 31 to deflect in the opposite direction around the inner wall of the docking groove 4. This causes the spool 32 to rotate in the opposite direction and release the previously wound traction rope length. The release of the second spring force pushes the slider 29 and the fifth connecting rod 30 to move in the groove 27 toward the receiving groove 21. Since the second spring force is greater than the first spring force, the end of the fifth connecting rod 30 will squeeze the groove wall of the pressure groove 26 after entering the pressure groove 26, forcing the fourth connecting rod 25 to move centripetally. This causes the retaining ball 23 to disengage from the retaining groove 24 and be received in the receiving groove 21, avoiding interference with the disengagement of the docking rod 16 from the docking hole 17, making it convenient and reliable.

[0058] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
