Description

Technical Field

[0001] The utility model belongs to flood control and flood fighting facilities, in particular to a flood control sub-dike with quick installation and corner functions. Background Art

[0002] A flood control sub-dike refers to a small dike temporarily built on the top of a dike, and its main purpose is to be a flood control and flood fighting facility to overcome the danger of flood overflow. It is usually stored as emergency rescue equipment in national, basin or provincial and municipal fixed-point warehouses, and is also directly equipped for mobile emergency rescue teams in each province, autonomous region and municipality.

[0003] Aiming at the problems of large occupied space and inconvenient handling of ordinary flood control sub-dikes, a foldable sub-dike with quick disassembly and installation is provided in the prior art. Existing flood control sub-dikes are arranged in a straight line, and the cross beams and brackets are mainly connected by threads and inserted joints. The problems of the above-mentioned flood control sub-dikes are as follows: First, the sub-dikes arranged in a straight line have great limitations in actual applications. At the corners of rivers or buildings, a water retaining structure needs to be built separately, which cannot meet the needs of rapid flood control. Second, when the cross beam and the bracket are connected by an inserted joint, generally, the cross beam is clamped on the bracket, the sub-body in the spring parent-child structure is installed on the cross beam, the parent body is installed on the bracket, and the spring's elastic force is used to squeeze the parent body snap ring to limit the sub-body to prevent it from coming out; the extrusion force is mainly provided by the spring's elastic force. The above structure will shake under the impact of floods and strong winds, and the stability is poor. Third, when the cross beam and the bracket are connected by threads, the first bracket needs to be installed for each sub-dike, all the required cross beams are placed and screwed tightly with the first bracket, and then the second bracket is installed at the other end of the cross beam, and so on for sequential installation. Otherwise, the cross beam cannot be installed. If several sub-dikes are installed separately and placed in the required positions to connect the waterproof plates to each other, because they are connected by threads, the cross beam is larger than the gap between two sub-dikes, and the adjacent sub-dikes cannot be reinforced by the cross beam, and the integrity is poor. If each sub-dike is not firmly fixed to the ground, it is easy to appear gaps; and the sequential installation of sub-dikes is slow and difficult to apply to the situation where a long flood control line needs to be established.

[0004] For the above reasons, those skilled in the art urgently need to develop a flood control sub-dike with quick installation, stable structure, corner and quick installation functions and capable of quickly building a long flood control line. The applicant has not found any patent literature reports in the domestic patent database that are the same as or similar to the present utility model. Summary of the Invention

[0041] Embodiment

[0042] The overall structure of this embodiment is as shown in the figure. The flood control sub-dike with quick installation and corner functions includes a support unit 1 composed of a support rod 1A, a connecting rod 1B, and a bottom rod 1C that are integrally triangular, hinged at the ends, and have a rectangular cross-section. A cross beam 3 is connected between adjacent support units 1, and a baffle 2 is assembled on the outer surface of the support unit 1 and / or the cross beam 3. Both ends of the cross beam 3 are fixedly connected to the inner sides of adjacent support units 1 through a connection mechanism 4. The connection mechanism 4 includes a first connection head 4A fixedly arranged at both ends of the cross beam 3, a second connection head 4B fixed to both sides of the support rod 1A, the connecting rod 1B, and the bottom rod 1C, and a clamp 5 for clamping and fixing the first connection head 4A and the second connection head 4B. The first connection head 4A and / or the second connection head 4B adopt a straight joint with a straight connection at the connection or a corner joint with a corner connection at the connection. The main function of the corner joint structure design is to facilitate the corner connection between the first connection head 4A and the second connection head 4B through the clamp 5, thereby solving the problem that existing products can only build a flood control line along a straight line and meeting the specific construction needs of the flood control line. The cross beam 3 can be installed after the support unit is installed and laid to the designated position. Due to the action of the connection mechanism 4, the cross beam 3 fixedly connects the first connection head 4A and the second connection head 4B into one body through the clamp 5. Compared with the threaded connection method used in the prior art, it is not necessary to align the threaded rod and the threaded hole during assembly, and standardized production and rapid assembly can be achieved.

[0043] The top of the first connection head 4A bulges to form a first stop plate 4C, and the top of the second connection head 4B bulges to form a second stop plate 4D. A stopping groove 5A adapted to the first stop plate 4C and the second stop plate 4D is provided in the clamp 5.

[0044] When the first connector 4A and the second connector 4B are angularly connected by a clamp 5, a flexible connection is adopted at the adjacent part of the baffle 2 corresponding to the angular connection.

[0045] Reinforcing parts are provided at the connection between the first stop plate 4C and the first connector 4A and at the connection between the second stop plate 4D and the second connector 4B. The function of the reinforcing parts is to prevent the connections between the first stop plate 4C, the second stop plate 4D and adjacent components from breaking due to excessive stress or fatigue.

[0046] The inner surface of the baffle 2 is fixedly assembled on the support unit 1 and / or the cross beam 3 by a spring clip 6, as Figure 10 、 10A shown. The spring clip 6 includes a mounting part 6A that can be fixedly connected to the inner surface of the baffle 2 through a mounting hole and a fastening member. Both ends of the mounting part 6A extend to form clamping parts 6B that can be fitted to the outer surface of the support unit 1 and / or the cross beam 3. The outer ends of the clamping parts 6B form clamping parts 6C that can prevent the support unit 1 and / or the cross beam 3 from coming out. The outer ends of the clamping parts 6C form an inlet part 6D for the support rod 1A, the connecting rod 1B, the bottom rod 1C, and the cross beam 3 to be inserted into. The inlet part 6D is in a flared shape. When in use, the cross beam 3 and / or the support rod 1A in the support unit 1 can be pushed into the spring clip 6, or an auxiliary device such as a wrench can be used to tighten the spring clip 6, so that the positioning and blocking effect of the clamping part 6C is better. When disassembling, an auxiliary device such as a wrench is needed to pull the spring clip 6 outwards to facilitate the removal of the support rod 1A of the cross beam 3 and / or the support unit 1.

[0047] The bottom rod 1C includes a first bottom rod 1C1 and a second bottom rod 1C2. The outer ends of the first bottom rod 1C1 and the second bottom rod 1C2 are hinged to the support rod 1A or the connecting rod 1B. One end of the middle bottom rod 1C3 is fixedly sleeved and inserted into the inner end of the first bottom rod 1C1 or the second bottom rod 1C2, and the other end of the middle bottom rod 1C3 is sleeved and inserted into the inner end of the first bottom rod 1C1 or the second bottom rod 1C2 and fixed by a spring pin 1C4. The bottom rod 1C will not shake due to flood or wind impact. When disassembling, the first bottom rod 1C1 and the second bottom rod 1C2 can be separated by pulling out the spring pin 1C4, enabling the support unit 1 to have a folding function;

[0048] A waterproof cloth is provided on the surface of the baffle 2. The baffle 2 adopts a corrugated waterproof board to achieve the function of convenient mutual lap joint.

[0049] It also includes a positioning member 7 that can fix the bottom rod 1C to an external foundation, capable of fixing the support unit 1 to the ground.

[0050] The waterproof cloth selects a double-composite plastic woven cloth that complies with the standard of QB / T 3808-1999. When in use, sandbags can be used to press it to meet the need for reliable positioning. The material of the baffle 2 is made of fiberglass reinforced plastic that complies with the standard of GB / T 15568-2008. The materials of the support rod 1A, the connecting rod 1B, and the bottom rod 1C in the support unit 1 are made of fiberglass reinforced plastic square tubes. The performance of the above fiberglass reinforced plastic square tubes meets the requirements of GB61539-2015, and the mechanical properties meet the M23 level.
