Description

Technical Field

[0001] This utility model belongs to the field of water barrier technology, specifically relating to a water barrier for flood control in water conservancy. Background Technology

[0002] Flood barriers are temporary protective devices used to prevent natural disasters such as floods and rainstorms from entering specific areas. They block water flow through physical barriers to protect flood-prone areas such as underground spaces and building entrances.

[0003] However, existing flood barriers are often spliced ​​together using snap-fit ​​mechanisms. Plastic flood barriers often have low structural strength and are prone to damage at the joints, causing inconvenience during use. In addition, existing flood barriers often lack anti-slip structures on the bottom, making them easy to be pushed away, which also causes inconvenience during use. Therefore, there is an urgent need for a flood barrier for water conservancy and flood control to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a water-blocking board for flood control in water conservancy, so as to solve the problems mentioned in the background art that existing water-blocking boards are often spliced ​​by snap-fit, plastic water-blocking boards often have low connection strength, and the bottom of existing water-blocking boards often do not have an anti-slip structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flood control barrier for water conservancy, comprising a barrier body, a fixing structure, and a splicing structure. The fixing structure includes a rubber pad and ground nails. The bottom of the barrier body is fixedly connected to the rubber pad. Three mounting holes are provided at both the left and right ends of the barrier body, and the ground nails are inserted into the mounting holes. The splicing structure includes a guide rail and a rod. The guide rail is fixedly connected to the rear left end of the barrier body, and the rod is fixedly connected to the rear right end of the barrier body. A threaded rod is threadedly connected to the top of the guide rail. A fixing rod is fixedly connected to the top of the threaded rod. A rotating seat is fixedly connected to the top of the fixing rod. A rotating shaft is rotatably connected to the rotating seat. An eccentric seat is rotatably connected to the rotating shaft. A pressure plate is slidably connected to the fixing rod. A pressure block is fixedly connected to the front side of the pressure plate, and the pressure block is slidably connected to the guide rail.

[0006] Preferably, the bottom surface of the rubber pad is provided with an uneven pattern.

[0007] Preferably, the rear end of the insertion rod is provided with an inverted trapezoidal slide bar, and the guide rail is provided with a slide groove corresponding to the insertion rod.

[0008] Preferably, the top of the guide rail is provided with an insertion port, and the bottom of the guide rail is provided with a limiting plate.

[0009] Preferably, the shape of the pressure block corresponds to the inverted trapezoidal slide bar of the insertion rod, and the thickness of the pressure block is greater than the thickness of the pressure plate.

[0010] Preferably, a handle is fixedly connected to the right side of the eccentric seat, and the surface of the handle is provided with an anti-slip sleeve.

[0011] Preferably, the bottom of the eccentric seat is provided with an arc-shaped protrusion, and the arc-shaped protrusion abuts against the top of the pressure plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of flood control barrier is equipped with a splicing structure. When two barriers need to be spliced ​​together, the operator aligns the insert rod of one barrier with the top of the guide rail on the adjacent barrier body and inserts it into the slot. The insert rod slides down the groove in the guide rail until it is stopped by the bottom limiting plate, completing the initial positioning. Then, the pressure plate is rotated so that the pressure block is at the top of the insert rod. The handle is rotated, causing the eccentric seat to rotate around the axis. The arc-shaped protrusion at the bottom of the eccentric seat rotates accordingly and presses down on the top of the pressure plate, forcing the pressure plate to move along the guide rail. As the fixed rod slides downward, the pressure block connected to the front of the pressure plate moves downward accordingly, tightly pressing and locking the insert rod, thus achieving a firm splicing of the two plates. This enables rapid splicing of the water-retaining plate and reliable mechanical self-locking. The insertion method of the insert rod and the guide rail simplifies the alignment steps and improves the installation speed. The pressure block is pressed down and locked by the eccentric seat, and the self-locking principle of the eccentric cam ensures the strength and stability of the connection point, effectively preventing the splice from loosening or separating due to water pressure, and greatly improving the reliability of the overall water-retaining wall.

[0013] 2. This type of flood control barrier has a fixed structure. When the barrier is deployed, the rubber pad at its bottom is in direct contact with the ground. The uneven pattern on the bottom of the rubber pad increases the friction with the ground. At the same time, the operator inserts ground nails through the mounting holes at both ends of the barrier and hammers them into the ground. The rubber pad deforms under the weight of the barrier and the pressure of the ground nails, conforming to the uneven ground and filling tiny gaps. This improves the bottom sealing and overall anti-slip stability of the barrier. As a flexible sealing medium, the rubber pad can adaptively compensate for the unevenness of the ground, effectively reducing the amount of water leaking from the bottom of the barrier. The pattern on its surface, combined with the anchoring effect of the ground nails, forms a dual fixing mechanism of anti-slip and anchoring, which greatly enhances the barrier's ability to resist flood erosion and thrust, preventing it from slipping or overturning.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides an embodiment of a flood control barrier for water conservancy, comprising a barrier body 1, a fixing structure 2, and a splicing structure 3. The fixing structure 2 includes a rubber pad 21 and ground nails 23. The bottom of the barrier body 1 is fixedly connected to the rubber pad 21. Three mounting holes 22 are provided at both the left and right ends of the barrier body 1, and the ground nails 23 are inserted into the mounting holes 22. The splicing structure 3 includes a guide rail 31 and a rod 32. The guide rail 31 is fixedly connected to the rear left end of the barrier body 1, and the rod 32 is fixedly connected to the rear right end of the barrier body 1. The top end of the guide rail 31 is threadedly connected to a threaded rod 33. The top end of the threaded rod 33 is fixedly connected to a fixing rod 34. The top end of the fixing rod 34 is fixedly connected to a rotating seat 35. The rotating seat 35 is rotatably connected to a rotating shaft 36. The rotating shaft 36 is rotatably connected to an eccentric seat 37. The fixing rod 34 is slidably connected to a pressure plate 39. The front side of the pressure plate 39 is fixedly connected to a pressure block 310. The pressure block 310 is slidably connected to the guide rail 31.

[0018] Furthermore, the bottom surface of the rubber pad 21 is provided with uneven patterns, which can significantly increase the static friction between the rubber pad 21 and the ground, effectively preventing the water barrier body 1 from sliding horizontally when impacted by water flow, thereby improving the stability of the entire flood control barrier.

[0019] Furthermore, the rear end of the insertion rod 32 is provided with an inverted trapezoidal slide bar, and the guide rail 31 is provided with a slide groove corresponding to the insertion rod 32. The inverted trapezoidal design enables the insertion rod 32 to achieve self-centering and pre-locking after being inserted into the guide rail 31, preventing it from accidentally coming out in the vertical direction, and providing convenience and basic protection for subsequent pressing operations.

[0020] Furthermore, the top of the guide rail 31 is provided with an insertion port, and the bottom of the guide rail 31 is provided with a limiting plate. The insertion port at the top provides a clear guide entrance for the insertion of the rod 32, which facilitates quick alignment, while the limiting plate at the bottom can reliably support the lower end of the rod 32, ensuring that the bottom of the multiple water-blocking plate bodies 1 can be aligned after splicing to form a neat water-blocking wall.

[0021] Furthermore, the shape of the pressure block 310 corresponds to the inverted trapezoidal slide bar of the insertion rod 32. The thickness of the pressure block 310 is greater than the thickness of the pressure plate 39, ensuring that the pressure block 310 can fully fit with the inclined surface of the insertion rod 32 and apply uniform clamping force. Its greater thickness provides sufficient structural strength and wear resistance to withstand the long-term load caused by repeated locking operations and water pressure.

[0022] Furthermore, a handle 38 is fixedly connected to the right side of the eccentric seat 37. The surface of the handle 38 is provided with an anti-slip sleeve. The added handle 38 provides the operator with a labor-saving and comfortable point of force application. The anti-slip sleeve on its surface can ensure that the operator can hold firmly in wet or emergency situations and prevent slippage, thereby quickly completing the locking or unlocking action.

[0023] Furthermore, the bottom of the eccentric seat 37 is provided with an arc-shaped protrusion, which abuts against the top of the pressure plate 39, converting the rotational motion of the eccentric seat 37 into a linear downward pressure on the pressure plate 39. By utilizing the force amplification characteristics of the cam mechanism, a large downward pressure can be generated at the pressure block 310 by applying a small rotational force through the handle 38, thereby achieving a firm mechanical locking.

[0024] Working principle: When two baffle plates 1 need to be joined together, the operator aligns the insertion rod 32 of one plate with the slot at the top of the guide rail 31 on the adjacent baffle plate 1 from above. The insertion rod 32 slides down the groove in the guide rail 31 until it is stopped by the bottom limiting plate, completing the initial positioning. Then, the pressure plate 39 is rotated so that the pressure block 310 is located on top of the insertion rod 32. The handle 38 is rotated to drive the eccentric seat 37 to rotate around the rotating shaft 36. The arc-shaped convex part at the bottom of the eccentric seat 37... The block rotates and presses downwards against the top of the pressure plate 39, forcing the pressure plate 39 to slide downwards along the fixed rod 34. The pressure block 310, connected to the front side of the pressure plate 39, moves downwards accordingly, tightly pressing against and locking the insertion rod 32, thereby achieving a firm splicing of the two plates. This enables rapid splicing of the baffle plate and reliable mechanical self-locking. The insertion method of the insertion rod 32 and the guide rail 31 simplifies the alignment steps and improves the installation speed. The pressure block 310 is driven downwards and locked by the eccentric seat 37, utilizing the self-locking of the eccentric cam. The principle ensures the strength and stability of the connection points, effectively preventing the splices from loosening or separating due to water pressure, greatly improving the reliability of the overall water retaining wall. When the water retaining plate body 1 is deployed, the rubber pad 21 fixed at its bottom is in direct contact with the ground. The uneven pattern on the bottom of the rubber pad 21 increases the friction with the ground. At the same time, the operator inserts the ground nails 23 through the mounting holes 22 at both ends of the water retaining plate body 1 and hammers them into the ground. Under the weight of the water retaining plate and the downward pressure of the ground nails 23, the rubber pad 21 deforms, conforms to the uneven ground, fills the tiny gaps, and improves the bottom sealing and overall anti-slip stability of the water retaining plate. As a flexible sealing medium, the rubber pad 21 can adaptively compensate for the unevenness of the ground, effectively reducing the amount of water leaking from the bottom of the plate. The pattern on its surface, combined with the anchoring effect of the ground nails 23, forms a dual fixing mechanism of anti-slip and anchoring, which greatly enhances the ability of the water retaining plate body 1 to resist flood erosion and thrust, preventing it from slipping or overturning.
