Description

Technical Field

[0001] This utility model relates to the field of flood control, and in particular to a flood control barrier for water conservancy projects. Background Technology

[0002] Flood control barriers are important facilities used for flood prevention and drainage, primarily to prevent floodwaters or accumulated water from entering specific areas and protecting people's lives and property. Traditional sandbag flood control methods are inefficient, time-consuming, and difficult to reuse. Flood control barriers were developed to address this need, employing a modular design that allows for rapid installation, flexible adjustment, and reusability. The movable panels are typically made of aluminum alloy, stainless steel, or composite materials, combining lightweight design with durability. Flood control barriers are widely used in urban streets, underground facilities, industrial parks, residential areas, and farmland, becoming a crucial technical means in modern flood control engineering, effectively improving flood control efficiency and emergency response capabilities.

[0003] There is a flood control barrier in the prior art, such as Chinese Patent Application No. CN202420600795.9, which mentions a flood control device for water conservancy projects, including a base, a flood control support mechanism and a positioning and storage mechanism set on the base; the positioning and storage mechanism includes a storage groove, a recess and a movable groove, the storage groove and the recess are set on the top wall of the base, the bottom wall of the storage groove is provided with a sliding groove, a slider is slidably arranged in the sliding groove, the side wall of the slider is provided with a locking groove, the movable groove is set in the base, the movable groove is located below the recess, and the movable groove is provided with a pressing component.

[0004] Existing technologies, such as the flood control device for water conservancy projects mentioned in the aforementioned patent, rely on only four conical short columns for base fixation. During flood control, the four conical short columns alone cannot provide sufficient stability. Furthermore, when installing on the ground, it is necessary to drill holes on-site to insert the conical short columns, which is not only not stable enough but also increases the time cost of flood control. Therefore, there is a need for a flood control barrier for water conservancy projects that is sufficiently stable and can be installed quickly. Summary of the Invention

[0005] To address the problem that existing flood control devices in water conservancy projects mostly rely on four conical short columns to fix the base, resulting in insufficient stability during flood control and the need for on-site drilling to install the conical short columns, which increases time costs and reduces emergency response efficiency, this utility model proposes a flood control baffle for water conservancy projects, solving the above-mentioned technical problems. The technical solution is as follows.

[0006] A flood control barrier for water conservancy projects includes a base plate and a movable plate that can be opened and closed and installed above the base plate. A foldable support mechanism is provided between the base plate and the movable plate. The support mechanism does not affect the fit between the movable plate and the base plate. The bottom surface of the base plate is provided with a plurality of fixing devices that can fix the entire flood control barrier to the ground.

[0007] The fixing device includes a fixing pile and a fixing sleeve. The fixing pile is perpendicular to the bottom surface of the base plate and is fixedly connected to the base plate. One end of the fixing sleeve is closed and the other end is open. The fixing pile can be coaxially inserted into the fixing sleeve from the open end of the fixing sleeve.

[0008] The fixed pile has several movable locking blocks embedded in its body, and a push-out mechanism is provided in the pile body. The push-out mechanism can push out or retract a part of the movable locking block from the side wall of the fixed pile. The inner wall of the fixed sleeve is provided with several fixing grooves. When the movable locking block is pushed into the fixing groove, the fixed pile is fixed to the fixed sleeve. When the movable locking block is retracted into the side wall of the fixed pile, the fixed pile can be pulled out from the fixed sleeve.

[0009] Furthermore, the ejection mechanism includes a longitudinal movable hole coaxially formed with the fixed pile. The longitudinal movable hole is a blind hole, and its opening is located on the top surface of the fixed pile. The side wall of the fixed pile has several transverse movable holes with axes perpendicular to the fixed pile. The transverse movable holes are connected to the longitudinal movable holes, and a movable locking block is coaxially movably arranged in the transverse movable hole. A top pin is coaxially movably inserted in the longitudinal movable hole. When the top pin moves downward in the longitudinal movable hole, it can push the movable locking block out to the side of the transverse movable hole away from the axis of the longitudinal movable hole and lock it into the fixing groove. When the top pin moves upward in the longitudinal movable hole, it can retract the movable locking block to the side of the transverse movable hole closer to the axis of the longitudinal movable hole, and the movable locking block is no longer locked into the fixing groove.

[0010] Furthermore, the movable block is a cylindrical block coaxial with the transverse movable hole. The end face of the movable block near the axis of the longitudinal movable hole is inclined upwards. The top pin has several slits with the slits inclined downwards. A sliding protrusion is provided on the inclined surface of the movable block. A groove matching the shape of the sliding protrusion is provided on the inclined surface of the slit. The sliding protrusion is slidably disposed in the groove and can move in the groove. When the top pin is pressed down, it pushes the movable blocks on both sides out of the transverse movable hole. When the top pin is pulled up, the movable blocks are pulled back into the transverse movable hole. A limiting protrusion is provided on the inner wall of the opening of the transverse movable hole. The limiting protrusion protrudes vertically into the transverse movable hole. The movable block has a second flange protruding outwards perpendicular to its own axis. The second flange is limited by the limiting protrusion, thereby preventing the movable block from completely dislodging from the transverse movable hole.

[0011] Furthermore, a fixing cover plate is provided at the top of the top pin. When the top pin is fully inserted into the movable hole, the fixing cover plate is fixed to the base plate, thereby fixing the top pin.

[0012] Furthermore, one side of the movable plate is hinged to the base plate on a single axis, and the movable plate can rotate relative to the base plate about the axis of the hinge. The support mechanism shown includes several support rods that are hinged to the movable plate on a single axis, and the rotation surface of the support rod about its own hinge is parallel to the rotation surface of the movable plate.

[0013] Furthermore, the base plate has several slots, and the support rod can be inserted into the slots for additional fixation.

[0014] The slot has several locking holes, and the angle of the axis of the locking hole relative to the base plate is set so that the support rod can be fixed at a specific angle. The support rod has a fixing hole perpendicular to its own axis. Pin seats are provided on both sides of the slot opening. The support rod can be locked by passing a fixing pin coaxially through the fixing hole and the pin seat.

[0015] Furthermore, several sturdy connecting rods are fixedly connected between the several support rods to distribute the force on the support rods.

[0016] Furthermore, the movable plate has several receiving grooves on the side of the plate near the bottom plate. The receiving grooves can accommodate the support rod and the stabilizing connecting rod. After the support rod and the stabilizing connecting rod are rotated into the receiving grooves, the movable plate is rotated towards the bottom plate so that the movable plate can be attached to the bottom plate. After the movable plate is attached to the bottom plate, the opposite side of the single-axis hinged side of the movable plate can be fixed to the movable plate to prevent the movable plate from moving.

[0017] This utility model has the following beneficial effects: By improving the fixing device and support mechanism, this utility model solves the problems of insufficient stability and time-consuming installation of existing flood control barriers. The fixing device adopts the cooperation of fixing piles and fixing sleeves, and realizes quick fixing and disassembly through movable blocks and ejection mechanism, which improves installation efficiency and stability. The support mechanism adopts a foldable design, which makes the movable plate fit tightly with the base plate, making it easy to store and transport. The overall structure is simple and reliable, suitable for flood control scenarios that require rapid deployment, significantly reducing time costs and enhancing flood resistance.

[0030] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, the fixed pile 3 has several movable locking blocks 5 embedded in its pile body, and the fixed pile 3 has an ejection mechanism in its pile body. The ejection mechanism can eject or retract a part of the movable locking block 5 from the side wall of the fixed pile 3. The inner wall of the fixed sleeve 4 has several fixing grooves 6. When the movable locking block 5 is ejected into the fixing groove 6, the fixed pile 3 is fixed to the fixed sleeve 4. When the movable locking block 5 is retracted into the side wall of the fixed pile 3, the fixed pile 3 can be pulled out from the fixed sleeve 4.

[0031] like Figure 5 , Figure 6 , Figure 7 As shown, preferably, the ejection mechanism includes a longitudinal movable hole 7 coaxially opened on the fixed pile 3.

The inclined surface of the cuts 10 is provided with a groove 12 that matches the shape of the sliding protrusion 11. The sliding protrusion 11 is slidably disposed in the groove 12 and can move in the groove 12. When the top pin 9 is pressed down, the movable blocks 5 on both sides are pushed out of the transverse movable hole 8. When the top pin 9 is pulled up, the movable blocks 5 are pulled back into the transverse movable hole 8.

[0033] like Figure 6 , Figure 8 , Figure 9 As shown, a limiting protrusion 13 is provided on the inner wall of the opening of the transverse movable hole 8. The limiting protrusion 13 protrudes vertically into the transverse movable hole 8. The movable block 5 is provided with a second flange 14 protruding outward perpendicular to its own axis. The second flange 14 is limited by the limiting protrusion 13, thereby preventing the movable block 5 from completely dislodging from the transverse movable hole 8.

[0034] like Figure 1 , Figure 7 As shown, preferably, the stroke of the top pin 9 in the movable hole will not cause the sliding protrusion 11 to come out of the groove 12, and the top of the top pin 9 is provided with a fixing cover plate 15. When the top pin 9 is fully inserted into the movable hole, the fixing cover plate 15 is fixed to the base plate 1, thereby fixing the top pin 9.

[0035] like Figure 1 , Figure 3 , Figure 4 As shown, preferably, one side of the movable plate 2 is hinged to the base plate 1 on a single axis.

A plurality of pin seats 21 are provided on both sides of the slot opening of the slot 17, and the support rod 16 can be locked by a fixing pin 22 passing through the fixing hole 23 and the pin seat 21 coaxially.

[0038] like Figure 1 , Figure 3 , Figure 4 As shown, preferably, a plurality of stable connecting rods 18 are fixedly connected between the plurality of support rods 16 to distribute the force on the support rods 16.

[0039] like Figure 1 , Figure 3 , Figure 4 As shown, preferably, the movable plate 2 has several receiving grooves 19 on the side of the plate near the base plate 1. The receiving grooves 19 can accommodate the support rod 16 and the stabilizing connecting rod 18. After the support rod 16 and the stabilizing connecting rod 18 are rotated into the receiving grooves 19, the movable plate 2 is rotated toward the base plate 1 so that the movable plate 2 can be attached to the base plate 1. After the movable plate 2 is attached to the base plate 1, the opposite side of the single-axis hinged side of the movable plate 2 can be fixed to the movable plate 2 to prevent the movable plate 2 from moving.

Then, the movable plate 2 is rotated and unfolded upward from the base plate 1, and the movable plate 2 is made perpendicular to the base plate 1 by using a single-axis hinge structure. The support rod 16 is then unfolded and inserted into the slot 17 on the base plate 1, ensuring... The movable plate 2 provides stable support; simultaneously, the stabilizing connecting rod 18 between the fixed support rods 16 distributes the force and enhances overall stability. After use, the stabilizing connecting rod 18 is removed, the support rods 16 are taken out of the slot 17 and rotated into the receiving slot 19 of the movable plate 2, and then the movable plate 2 is rotated towards the base plate 1 to fit it against the base plate 1 for storage. Finally, the top pin 9 is pulled upwards to retract the movable locking block 5 into the side wall of the fixed pile 3, releasing the lock with the fixed sleeve 4, and the fixed pile 3 is pulled out of the fixed sleeve 4 to complete disassembly. Through the above steps, the flood control baffle can achieve rapid installation, stable support, and convenient storage, and is suitable for flood control scenarios in water conservancy projects.
