fig. 2 is a top view of a floating block in the self-collapsing protector of the rubber dam of the present invention.

In the figure: the device comprises a rubber dam bag 1, a communicating pipe 2, a water discharging pipe 3, a hollow pipe 4, a first vertical bar 5, a return spring 6, a steering ring 7, a pull rope 8, a second vertical bar 9, a floating block 10, a through hole 11 and a limiting ring 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a rubber dam self-collapsing protection device comprises a rubber dam bag 1, wherein the rubber dam bag 1 has the highest horizontal line, a communicating pipe 2 communicated with the rubber dam bag 1 is installed at the bottom of the rubber dam bag 1, the communicating pipe 2 is in a J-shaped shape, the upper end of the high end of the communicating pipe 2 is higher than the upper end of the rubber dam bag 1, and a shorter vertical pipe of the communicating pipe 2 is communicated with the rubber dam bag 1.

The bottom fixedly connected with of communicating pipe 2 and its drain pipe 3 that communicates each other, the inner wall sliding connection of communicating pipe 2 has the hollow tube 4 of shutoff drain pipe 3, be equipped with canceling release mechanical system between hollow tube 4 and the inner wall of communicating pipe 2, canceling release mechanical system is including fixing the last first vertical retort 5 of communicating pipe 2 inner wall, fixedly connected with reset spring 6 between first vertical retort 5 and the hollow tube 4, reset spring 6's outer wall is equipped with the flexible glue gum cover, can protect reset spring 6, make it be difficult for receiving the erosion of water.

The inner wall of the communicating pipe 2 is connected with a floating block 10 in a sliding way, and a plurality of through holes 11 are arranged on the floating block 10 in a vertical penetrating way, so that a communicating vessel is formed between the communicating pipe 2 and the rubber dam bag 1; be connected through stay cord 8 between floating block 10 and the hollow tube 4, stay cord 8 is the nylon rope, and one side fixedly connected with second vertical bar 9 that hollow tube 4 and first vertical bar 5 carried on the back mutually drives stay cord 8 and 9 fixed connection of second vertical bar, the inner wall fixedly connected with steering ring 7 of communicating pipe 2, stay cord 8 run through steering ring 7 and rather than sliding connection.

The inner wall fixedly connected with spacing ring 12 of communicating pipe 2 prevents that floating block 10 from dropping downwards, leads to the lax phenomenon of knoing of stay cord 8 to appear, and spacing ring 12 is located the below of floating block 10.

In the utility model, as the water quantity of the rubber dam bag 1 increases, the water quantity in the communicating pipe 2 also increases gradually and is always flush with the water level line in the rubber dam bag 1 (communicating vessel principle); along with the increase of the water level in the rubber dam bag 1, the water amount in the communicating pipe 2 is gradually increased, when the water is abutted against the floating block 10, the water amount is gradually increased, the floating block 10 moves upwards, the second vertical bar 9, the hollow pipe 4 and the first vertical bar 5 can move through the pull rope 8, and the pipe orifice of the drain pipe 3 is slowly opened; when the rubber dam bag 1 reaches the highest horizontal line, the floating block 10 drives the hollow pipe 4 to move, the drain pipe 3 is completely opened, and water is discharged through the drain pipe 3, so that automatic dam collapse is realized, manual operation is not needed, the life safety and property safety of people are guaranteed, and manual operation is not needed.

With the discharge of water in the rubber dam bag 1, the water quantity is reduced, the corresponding floating block 10 moves downwards due to gravity and the pulling force of the return spring 6, the discharge quantity of air passing through the through hole 11 can be blocked under the action of the through hole 11, the downward moving speed of the floating block 10 is further slowed down, the speed of plugging the drain pipe 3 is reduced, and more water can be drained; when the hollow pipe 4 is completely reset, the hollow pipe plugs the drain pipe 3, the floating block 10 abuts against the limiting ring 12, and then a communicating vessel is formed between the communicating pipe 2 and the rubber dam bag 1 again.

The water in the rubber dam bag 1 can be drained again when the water level is increased to the highest water level again, and then the water can be automatically closed without manual operation.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
