DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following are specific embodiments of the utility model and in conjunction with the drawings, the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.

[0022] Such as Figures 1 - 5As shown, a flood control and water retaining plate comprises at least one L-shaped plate body 1 and a plurality of counterweights 2. A slide groove 11 is provided on one side of the top of the plate body 1, and a sliding portion 12 that can be inserted into the slide groove 11 and slidably cooperate with it is provided on the other side. A slot 13 is provided on one side of the bottom of the plate body 1, and a plug-in portion 14 that can be inserted into the slot 13 and fixed is provided on the other side. The plate body 1 protrudes from its lower surface to the upper surface to form at least one L-shaped supporting keel 15 with an inner concave cavity 151. The supporting keel 15 mainly serves to prevent the L-shaped plate body 1 from bending and deformation and to improve the compressive strength. A counterweight groove 16 for embedding the counterweight 2 is formed on the lower end surface of the bottom of the plate body 1. The counterweight groove 16 is through-connected with the inner concave cavity 151. Ball head plungers 3 are symmetrically threaded on both sides of the counterweight 2. Slide rails 4 are fixedly connected to the two side walls of the counterweight groove 16. Rolling grooves 41 are provided on the slide rails 4 for the balls on the ball head plungers 3 to roll in.

[0023] The working principle of the utility model in actual use is: multiple plates 1 are combined for use, the sliding portion 12 of one of the plates 1 is inserted into the slide groove 11 of the adjacent plate 1, and the plug-in portion 14 of the plate 1 is inserted into the slot 13 of the adjacent plate 1 for fixing, and several plates 1 are sequentially connected according to the above connection method to form a water retaining wall;

[0024] The installation of the counterweight block 2 is to align the counterweight block 2 with the counterweight groove 16 and press it to make it embedded between the two symmetrical slide rails 4. During this period, the ball on the ball plunger 3 and the side wall of the slide rail 4 are squeezed into the ball plunger 3 until the ball docks with the rolling groove 41 and pops out again. The number of counterweight blocks 2 to be installed can be selected according to the actual possible precipitation and water level height;

[0025] To remove the counterweight block 2, since the counterweight groove 16 is connected to the inner concave cavity 151, it is only necessary to push the counterweight block 2 into the inner concave cavity 151 from one side. During this period, the ball rolls along the rolling groove 4, causing the ball of the ball head plunger 3 to retract into the ball head plunger 3, so that the counterweight block 2 can slide into the inner concave cavity 151 and disengage from the counterweight groove 16.

[0026] Furthermore, if Figure 4 As shown, the counterweight groove 16 is 80 mm-200 mm away from the side of the bottom of the board body 1 facing the water.

[0027] A water-stopping rubber strip 5 is fixedly connected to the edge of the lower end surface of the bottom of the plate body 1 .

[0028] The counterweight groove 16 is close to the bottom of the board body 1 and faces the water side, and has a downward pressure, so that the waterproof rubber strip 5 fits more closely with the ground, preventing the water pressure from impacting the board body 1 upward and causing overturning.

[0029] Furthermore, if Figure 5As shown, the inner side of the lower end of the slide rail 4 is chamfered, so that the ball on the ball plunger 3 is in smooth pressing contact with the inner side wall of the slide rail 4, and then the ball on the ball plunger 3 is quickly introduced into the rolling groove 41.

[0030] At the connection between the rolling groove 41 and the concave cavity 151, there is a guiding inclined surface 411. The ball rolls along the rolling groove 4 and finally fits and presses against the guiding inclined surface 411, making it more labor-saving to push the counterweight 2 into the concave cavity 151.

[0031] At the top of the plate body 1, there is a handle 17 for manual lifting, which is convenient for installation and recovery.

[0032] The counterweight 2 is made of cast iron or cast aluminum. Cast iron or cast aluminum is low in price, good in hardness, large in density, wear-resistant and corrosion-resistant, and is suitable for use as a counterweight.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
