Description
Technical Field
[0001] This utility model relates to the field of flood control equipment technology, and in particular to an assembled emergency flood control baffle. Background Technology
[0002] In recent years, global climate change has intensified, and extreme rainfall and floods have become more frequent, posing a serious threat to urban infrastructure and the safety of residents' lives and property. Traditional flood control measures (such as sandbags and concrete embankments) suffer from problems such as low deployment efficiency, high transportation costs, and poor reusability, making it difficult to meet the needs for rapid response and flexible flood control.
[0003] In existing technologies, flood barriers, as a modular flood control device, are gradually becoming an important solution for urban flood control. They are typically made of metal, plastic, or composite materials, and are assembled to form temporary barriers, offering advantages such as convenient installation and reusability. However, current flood barriers on the market suffer from inflexibility in height adjustment. For example, patent CN202120163041.8 discloses a flood barrier assembly composed of several flood barriers connected and fixed by a fixing mechanism. Each flood barrier includes a vertically L-shaped body and reinforcing ribs distributed on its surface. The body consists of a vertically placed water-retaining plate and a horizontally placed fixed base plate, which are an integral structure. However, this type of flood barrier cannot be assembled and heightened as the water level rises. Preparing multiple sets of flood barriers of different specifications not only lacks flexibility but is also difficult to store. Therefore, some modular flood barriers have emerged that can be flexibly assembled longitudinally to raise the water-blocking position. However, after the flood barriers are assembled and raised, the longitudinal joints are prone to seepage and separation under the impact of high-pressure water flow. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of the prior art and provide an assembled emergency flood control barrier.
[0005] The objective of this utility model is achieved through the following technical solution: an assembled emergency flood control baffle, comprising several horizontally assembled L-shaped baffles; an extension baffle is assembled at the upper end of the L-shaped baffles; the extension baffle is used to extend the longitudinal height of the flood control baffle; the L-shaped baffle includes an integrally formed vertical plate and a bottom plate; a first reinforcing rib is provided on one side surface of the vertical plate; a first groove is provided on the other side surface of the vertical plate corresponding to the position of the first reinforcing rib; a second reinforcing rib is provided on the upper surface of the bottom plate; a second groove is provided on the lower surface of the bottom plate corresponding to the position of the second reinforcing rib; the first reinforcing rib and the second reinforcing rib are connected; a third reinforcing rib is provided on one side surface of the extension baffle; a third groove is provided on the other side surface of the extension baffle corresponding to the position of the third reinforcing rib; a support column is movably installed in the first groove or the third groove; the L-shaped baffles can be assembled horizontally using conventional snap-fit connections, for example, by providing several protrusions at intervals on one side edge of the L-shaped baffle, and on the other side edge of the L-shaped baffle... The interface is provided with corresponding protrusions to assemble the L-shaped baffles on both sides together. The L-shaped baffles and the raised baffles can be made of waterproof plastic material, and any suitable material can be selected as needed. The L-shaped baffles can be assembled laterally to extend their horizontal length and adapt to different terrains. In the longitudinal direction, the upper part of the L-shaped baffles can be assembled with raised baffles to flexibly adjust the height of the flood control baffles. The L-shaped baffles include an integrally formed vertical plate and a bottom plate. The vertical plate has a first reinforcing rib on one side surface and a first groove on the other side surface. The bottom plate has a second reinforcing rib on the upper surface and a second groove on the lower surface corresponding to the second reinforcing rib. The raised baffle has a third reinforcing rib on one side surface and a third groove on the other side surface corresponding to the third reinforcing rib. This facilitates stacking and storage when not in use. At the same time, the groove structure of the first and third grooves allows for the connection of support columns inside, which facilitates the installation of support columns as needed, improves structural strength, and prevents the raised baffles from separating from the vertical plate when the water pressure is too high.
[0006] The top of the vertical plate is provided with a first slot; the bottom of the heightening baffle is provided with a locking strip corresponding to the first slot; the top of the heightening baffle is provided with a second slot corresponding to the locking strip; the second slot is used to continue to assemble the heightening baffle vertically upwards; the heightening baffle is inserted into the first slot to extend the vertical height of the L-shaped baffle, and the heightening baffle can be further increased with the help of the second slot and locking strip, so as to flexibly adjust the height of the flood control baffle.
[0007] Waterproof strips are provided on both sides of the card strip; the upper edge of the waterproof strip is connected to the side surface of the raised baffle; the lower edge of the waterproof strip is connected to the side surface of the vertical plate or the raised baffle below; the waterproof strips are provided on both sides of the card strip, and the waterproof strips are made of flexible waterproof plastic material. The waterproof strips help to ensure the sealing of the connection of the raised baffle and prevent water leakage. The lower edge of the waterproof strip can be connected to the side surface of the vertical plate below or the raised baffle below, and can be connected by magnetic, snap fastener or Velcro or other connection methods.
[0008] A connecting strip is provided on one side of the heightening baffle; a connecting groove is provided on the other side of the heightening baffle corresponding to the connecting strip; the connecting strip is movably engaged in the connecting groove for the lateral assembly of the heightening baffle; after the connecting strip and the connecting groove of the heightening baffle are connected, it is beneficial for the heightening baffle to be assembled laterally.
[0009] The bottom of the L-shaped baffle is also equipped with an anti-slip mat; the anti-slip mat is made of conventional anti-slip material. As the water pressure on the L-shaped baffle increases, the pressure between the anti-slip mat and the ground can be increased, which helps to improve the grip effect.
[0010] The support column includes a column body and an anti-slip base; the bottom of the anti-slip base is provided with an anti-slip sheet; the top of the anti-slip base is provided with an installation groove; the lower end of the column body is inserted into the installation groove of the anti-slip base; the upper end of the column body extends outward with a claw; a first groove is provided in the first groove corresponding to the claw; a second groove is provided in the third groove corresponding to the claw; the support column is made of conventional materials with certain mechanical strength, and any reasonable material can be selected as needed. The support column can provide support on the back of an L-shaped baffle or a raised baffle. In use, the claw is engaged in the first or second groove, the bottom is inserted into the anti-slip base, and the anti-slip base is placed on the ground to prevent the raised baffle from separating under water pressure.
[0011] A further technical solution involves providing elastic buckles on both sides of the first groove; the support column is housed within the first groove and locked in place by the elastic buckles; when the water level is low and the support column is not needed, it can be temporarily housed in the first groove instead of being stored in a warehouse. As the water level changes, the support column can be directly removed and installed on-site, saving installation time and improving the mobility of emergency flood control. The elastic buckles have a certain deformation force, so stacking L-shaped baffles after the flood level rises does not affect the insertion of the first reinforcing rib in the first groove; the number of the first groove and the first reinforcing rib can be set to an odd number, with the elastic buckles positioned in the middle of the first groove. During storage, the support column is installed in the middle of the first groove to avoid imbalance.
[0012] This utility model has the following advantages: 1. The L-shaped baffle of this utility model can be assembled and extended in the horizontal direction to adapt to different terrains. In the vertical direction, the upper part of the L-shaped baffle can be assembled with a heightening baffle to flexibly adjust the height of the flood control baffle. 2. The L-shaped baffle includes an integrally formed vertical plate and a bottom plate. A first reinforcing rib is provided on one side of the vertical plate, and a first groove is provided on the other side. A second reinforcing rib is provided on the upper surface of the bottom plate, and a second groove is provided on the lower surface of the bottom plate corresponding to the position of the second reinforcing rib. A third reinforcing rib is provided on one side of the raised baffle, and a third groove is provided on the other side of the raised baffle corresponding to the position of the third reinforcing rib. When not in use, it is convenient to stack and store. At the same time, with the groove structure of the first and third grooves, support columns can be connected inside. It is convenient to install support columns as needed, improve structural strength, and prevent the raised baffle from separating from the vertical plate when the water pressure is too high.
