Description

Technical Field

[0001] This utility model relates to the field of flood control barrier technology, specifically an adjustable flood control barrier. Background Technology

[0002] Water conservancy projects are a systematic undertaking that scientifically develops and effectively utilizes water resources and is dedicated to preventing and controlling floods. Water conservancy construction is a crucial foundation for ensuring the sustainable socio-economic development of a region, directly impacting the safety of people's lives and property and social stability. Among the many aspects of water conservancy work, flood control and disaster reduction are paramount and have become one of the core functions of governments at all levels. In responding to sudden floods, the rapid construction of temporary flood barriers is a common emergency response method, making flood barriers a key piece of basic equipment that plays an irreplaceable role in protecting people's lives and property.

[0003] In the prior art, various flood control baffle structures have been proposed. For example, Chinese utility model patent (publication number: CN222206177U) discloses a flood control baffle that achieves flexible adjustment of the water-blocking area by setting a second baffle that can move relative to the main baffle, thereby improving the adaptability and efficiency of a single baffle unit to different water levels.

[0004] However, analysis revealed significant shortcomings in this existing technology: its core improvement lies in the scalability of individual baffles, but it lacks an efficient and reliable inter-baffle connection mechanism. When large-scale deployment is required, involving the horizontal splicing of multiple sets of first and second baffles to form a continuous flood barrier, the docking operations between units are cumbersome and time-consuming, and the overall integrity and sealing of the connection are difficult to guarantee. In the fast-paced flood control and rescue operations, this inefficient assembly method severely delays flood control efforts, increases the risk of escalating the danger, and fails to meet the practical needs of rapid response and emergency deployment. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable flood control barrier to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable flood control baffle, comprising a baffle body, wherein a connecting groove is provided inside the baffle body, an extension plate is slidably connected to the inner wall of the connecting groove, a bolt is provided at the top of the baffle body, the bolt penetrates the baffle body and is threadedly connected to the baffle body, two sets of extension plates are provided, and a connecting component and a limiting component are provided on the outer surface of the extension plate;

[0007] The connection component includes:

[0008] The docking groove is used to connect with the fixed column.

[0009] The card slot is used to cooperate with the card block to achieve limit positioning;

[0010] Release element, used to release the limit for easy separation.

[0011] Preferably, the docking groove is formed on the outer surface of one of the two sets of extension plates. A retaining groove is formed on the inner wall of the docking groove. A fixing post is fixed to the outer surface of the other set of extension plates. A cavity is formed inside the fixing post. A retaining block is slidably connected to the inner wall of the cavity. A spring is fixed to the outer surface of the connecting post fixed to the inner wall of the cavity. The end of the spring away from the connecting post is fixed to the outer surface of the retaining block. The end of the retaining block away from the spring passes through the fixing post. When docking is required, the fixing post is installed into the docking groove, and the retaining block enters the retaining groove. The side of the retaining block away from the inclined surface abuts against the inner wall of the retaining groove, thereby limiting the movement between the extension plates and completing the rapid docking.

[0012] Preferably, the release mechanism includes a circular plate rotatably connected to the inner wall of cavity one, away from the locking block. An extension plate has a second cavity inside, and a worm gear is rotatably connected to the inner wall of cavity two. A rotating rod is fixed to the side of the circular plate away from the locking block, with one end of the rotating rod passing through cavity two. A knob is rotatably connected to the top of the extension plate, and the output shaft of the knob passes through the extension plate. A long rod is rotatably connected to the inner wall of cavity two, and a worm gear is fixed to the outer surface of the long rod, meshing with a worm wheel. A through hole is formed on the outer surface of the circular plate, and a circular rod is fixed to the inner wall of the through hole. One end of the circular rod away from the through hole is fixed to the outer surface of the locking block. When separation is required, rotating the knob causes the long rod, worm gear, worm wheel, rotating rod, and circular plate to rotate. The arc-shaped inner wall of the through hole abuts against the outer surface of the circular rod, causing each circular rod and the locking block to move radially synchronously and disengage from the locking groove, thereby releasing the limiting position.

[0013] Preferably, the limiting component includes a fixing block fixed to the top of the extension plate. The fixing block has a cavity three inside, and an L-shaped rod slidably connected to the inner wall of the cavity three. The L-shaped rod passes through the fixing block, and a groove is formed on the outer surface of the L-shaped rod. A stabilizing column is slidably connected to the inner wall of the groove, and a spring two is fixed to the outer surface of the stabilizing column. The end of the spring two away from the stabilizing column is fixed to the inner wall of the groove. A stabilizing groove is formed on the inner wall of the cavity three, and a limiting groove is formed on the outer surface of the knob. Two sets of stabilizing grooves are provided. When the L-shaped rod enters the limiting groove, it locks the knob to prevent it from rotating. During removal, the L-shaped rod is pulled outward to disengage from the limiting groove, and simultaneously the stabilizing column engages in the new stabilizing groove, fixing the position of the L-shaped rod. The knob can then be rotated normally for operation.

[0014] Preferably, the side of the through hole closest to the round rod is set to be arc-shaped, so that it abuts against the outer surface of the round rod when the round plate rotates, which can make each round rod and the locking block move radially synchronously.

[0015] Preferably, the end of the locking block away from the spring is set as an inclined surface, so that when it is pressed, the locking block can move into the cavity without affecting normal docking.

[0016] Preferably, the end of the stabilizing column away from the second spring is set in an arc shape. When the stabilizing column moves with the L-shaped rod, its surface abuts against the inner wall of the stabilizing groove, allowing it to enter the sliding groove without affecting the normal movement of the L-shaped rod.

[0017] Compared with the prior art, this utility model provides an adjustable flood control baffle, which has the following beneficial effects:

[0018] 1. This adjustable flood control baffle, through its connecting components, allows for quick and easy docking when the fixed column is installed into the docking slot. A spring then engages the locking block within the slot. The side of the locking block away from the inclined surface abuts against the inner wall of the slot, limiting the movement of the extension plates. When separation is required, rotating the knob causes the long rod, worm gear, worm wheel, rotating rod, and circular plate to rotate. The arc-shaped inner wall of the through hole abuts against the outer surface of the circular rod, causing the rods and locking block to move radially synchronously and disengage from the slot, thus releasing the limiting mechanism and allowing for normal separation and easy retrieval.

[0019] 2. This adjustable flood control baffle, through its set limiting components, ensures that when the extension plates are connected, the L-shaped rod enters the limiting groove, locking the knob to prevent it from rotating on its own, thus avoiding accidental contact or unforeseen impact on the stability of the connection. During removal, pull the L-shaped rod outward to disengage it from the limiting groove, and simultaneously, the stabilizing post engages in the new stabilizing groove, fixing the position of the L-shaped rod. At this point, the knob can be rotated normally for operation. Attached Figure Description

[0027] like Figure 1-6 As shown, this utility model provides a technical solution: an adjustable flood control baffle, including a baffle body 1, a connecting groove 6 is provided inside the baffle body 1, an extension plate 2 is slidably connected to the inner wall of the connecting groove 6, a bolt 3 is provided on the top of the baffle body 1, the bolt 3 penetrates the baffle body 1 and is threadedly connected to the baffle body 1, two sets of extension plates 2 are provided, and a connecting component 4 and a limiting component 5 are provided on the outer surface of the extension plate 2; the connecting component 4 includes: a docking groove 40, a slot 41, a fixing post 42, a cavity 1 43, a connecting post 44, a spring 1 45, a locking block 46, a release component 47, a round plate 470, a through hole 471, a round rod 472, a rotating rod 473, a cavity 2 474, a worm gear 475, a knob 476, a long rod 477, and a worm gear 478.

[0028] A docking groove 40 is formed on the outer surface of one of the two sets of extension plates 2. A slot 41 is formed on the inner wall of the docking groove 40. A fixing post 42 is fixed on the outer surface of the other set of two sets of extension plates 2. A cavity 43 is formed inside the fixing post 42. A locking block 46 is slidably connected to the inner wall of the cavity 43. A spring 45 is fixed on the outer surface of a connecting post 44 fixed to the inner wall of the cavity 43. The end of the spring 45 away from the connecting post 44 is fixed to the outer surface of the locking block 46. The end of the locking block 46 away from the spring 45 passes through the fixing post 42. The release member 47 includes a circular plate 470. The circular plate 470 is rotatably connected to the inner wall of the cavity 43 away from the locking block 46. A cavity 474 is formed inside the extension plate 2. A worm gear 475 is rotatably connected to the inner wall of the cavity 474. A rotating rod 473 is fixed on the side of the circular plate 470 away from the locking block 46. 73 has one end away from the circular plate 470 that passes through the cavity 474. A knob 476 is rotatably connected to the top of the extension plate 2. The output shaft of the knob 476 passes through the extension plate 2. A long rod 477 is rotatably connected to the inner wall of the cavity 474. A worm gear 478 is fixed to the outer surface of the long rod 477. The worm gear 478 meshes with the worm wheel 475. A through hole 471 is opened on the outer surface of the circular plate 470. A round rod 472 is fixed to the inner wall of the through hole 471. One end of the round rod 472 away from the through hole 471 is fixed to the outer surface of the locking block 46. The side of the through hole 471 near the round rod 472 is set as an arc. The end of the locking block 46 away from the spring 45 is set as a slope. When docking is required, the fixing post 42 is installed into the docking groove 40. At this time, the slope of the locking block 46 abuts against the inner wall of the docking groove 40, causing the locking block 46 to move into the cavity 43. At the same time, the spring 45 is compressed. When the locking block 46 moves to a position parallel to and aligned with the slot 41, the spring 45 releases, causing the locking block 46 to reset and enter the slot 41. At this time, the side of the locking block 46 away from the inclined plane abuts against the inner wall of the slot 41, limiting the movement between the extension plates 2 and completing the quick docking. When separation is required, the knob 476 is turned, causing the long rod 477 and the worm gear 478 to rotate synchronously, which in turn drives the worm wheel 475, the rotating rod 473, and the circular plate 470 to rotate synchronously. At this time, the arc-shaped inner wall of the through hole 471 abuts against the outer surface of the circular rod 472, causing each circular rod 472 and the locking block 46 to move radially synchronously and disengage from the slot 41, thereby releasing the limitation and achieving normal separation.

[0029] The limiting component 5 includes a fixing block 50, which is fixed to the top of the extension plate 2. A cavity 51 is formed inside the fixing block 50. An L-shaped rod 52 is slidably connected to the inner wall of the cavity 51. The L-shaped rod 52 passes through the fixing block 50. A groove 54 is formed on the outer surface of the L-shaped rod 52. A stabilizing column 55 is slidably connected to the inner wall of the groove 54. A spring 56 is fixed to the outer surface of the stabilizing column 55. The end of the spring 56 away from the stabilizing column 55 is fixed to the inner wall of the groove 54. A stabilizing groove 57 is formed on the inner wall of the cavity 51. A limiting groove 53 is formed on the outer surface of the knob 476. Two sets of stabilizing grooves 57 are provided. The end of the stabilizing column 55 away from the spring 56 is set to be arc-shaped. The L-shaped rod 52 enters the limiting groove 53, which can lock the knob 476 to prevent it from rotating. During disassembly, pull the L-shaped rod 52 outward to disengage it from the limiting groove 53. During this process, the stabilizing column 55 is squeezed by the inner wall of the stabilizing groove 57, retracting into the sliding groove 54 and compressing the second spring 56. When the stabilizing column 55 moves to align with the next set of stabilizing grooves 57, the second spring 56 is released, pushing the stabilizing column 55 into the new stabilizing groove 57, thereby fixing the position of the L-shaped rod 52. This design eliminates the need for continuous pulling by personnel; the knob 476 can then be rotated normally for operation.

[0030] When the width between the baffle bodies 1 needs to be adjusted, rotate bolt 3 to disengage from extension plate 2. Extension plate 2 can then be pulled normally. When adjusted to the appropriate position, rotate bolt 3 to contact the top of extension plate 2, stabilizing it. When docking is required, install fixing post 42 into docking groove 40. The inclined surface of locking block 46 contacts the inner wall of docking groove 40, allowing locking block 46 to move into cavity 43. Simultaneously, spring 45 is compressed. When locking block 46 is parallel to groove 41, spring 45 is released, causing locking block 46 to reset and enter groove 41. The side of locking block 46 away from the inclined surface contacts the inner wall of groove 41, limiting the distance between extension plates 2 for quick docking and convenient use. Simultaneously, L-shaped rod 52 enters limiting groove 53, limiting knob 476 and preventing knob 47 from being rotated. 76. The rotation affects stability. When disassembly is required, pull the L-shaped rod 52 to disengage from the limiting groove 53. At the same time, the outer surface of the stabilizing column 55 abuts against the inner wall of the stabilizing groove 57, causing the stabilizing column 55 to move into the sliding groove 54. At this time, the second spring 56 is compressed. When the position of the stabilizing column 55 is parallel to another set of stabilizing grooves 57, the second spring 56 is released, which can drive the stabilizing column 55 into the stabilizing groove 57, thus stabilizing the L-shaped rod 52. There is no need for personnel to pull the L-shaped rod 52 for a long time. At this time, turn the knob 476 to drive the long rod 477 and the worm gear 478 to rotate synchronously, which can drive the worm wheel 475, the rotating rod 473, and the circular plate 470 to rotate synchronously. At this time, the arc-shaped interior of the through hole 471 abuts against the outer surface of the circular rod 472, which can cause each circular rod 472 and the locking block 46 to move radially synchronously and disengage from the locking groove 41, thus releasing the limit. At this time, normal separation can be achieved.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
