Technical Field

The invention relates to the field of traffic safety facilities, in particular to a quick-open type bridge bottom road accumulated water safety warning device.

Background

Along with the increase of vehicles, the pressure of road trip is bigger and bigger, in order to alleviate traffic pressure, fast channels such as bridge of building can realize shunting decompression, but the sunken road of underpass bridge produces ponding easily in rainy day, and ponding probably can make the vehicle flame out.

The conventional accumulated water safety warning device is a warning board usually placed manually, the warning time is not timely enough, and the warning board placed on the roadside cannot prompt a driver of a vehicle effectively.

Disclosure of Invention

The invention aims to solve the defects of untimely warning and unobtrusive warning in the prior art, and provides a quick-opening type safety warning device for accumulated water on a bridge bottom road.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a quick open type road ponding safety warning device at bottom of bridge, is including installing the fixed plate at the bottom of the bridge, on the fixed plate respectively the symmetry install two pistols and two peg, every the flexible end of pistil all rotates and installs the pinch bar, every spout has all been seted up on the pinch bar, every the lower extreme of peg all slides and rotates and install in the spout that corresponds, every the one end that the pistil was kept away from to the pinch bar all rotates and installs the kickoff, every the kicking block is all installed to the lower extreme of kickoff, the warning jar is installed to the centre of fixed plate, two flat tubes, every are installed to the lateral wall symmetry of warning jar the lower bottom surface of flat tube is impartial apart from installing a plurality of book rubber tubes.

Preferably, each floating rod is sleeved with a limiting sleeve in a sliding mode, and each limiting sleeve is fixed on the side wall of the pier.

Preferably, each piston device is provided with a pressure pipe on the side wall close to the telescopic end, and the two pressure pipes are fixedly inserted on the warning tank and far away from the two flat pipes.

Preferably, a sealing plate is slidably mounted in the warning tank, a first magnetic block is mounted on the lower bottom surface of the sealing plate, a second magnetic block is mounted on the inner bottom wall of the warning tank, a pressure spring is mounted between the first magnetic block and the second magnetic block, and the sealing plate is located above the two flat tubes.

Preferably, the distance from the floating rod to the sliding groove is greater than the distance from the piston device to the sliding groove, and the height of the upper end of the floating rod is lower than that of the lower end of the hanging rod.

The invention has the following beneficial effects:

1. through utilizing the floating block to detect road ponding degree of depth at the bottom of the bridge, the floating block rises under buoyancy and through the kicking lever that makes progress of floating rod, make the telescopic end of crowbar use the lower extreme of peg to prize the piston ware as the fulcrum, make atmospheric pressure in the piston ware pass through the connecting pipe and get into in the warning jar and through the plain tube a plurality of rubber of rolling up intraductal, make a plurality of rubber of rolling up pipes stretch out under the effect of atmospheric pressure and straighten, it is too deep to remind the vehicle ponding that is about to arrive, increase the striking degree of warning, and the rubber of rolling up pipe is comparatively soft, even the vehicle also can't cause the damage to the vehicle because the speed of passing the rubber of stopping too fast, the security of increase device.

2. By arranging the sealing plate, the first magnetic block, the second magnetic block and the pressure spring in the warning tank, the floating rod prizes the piston device through the prying rod to exhaust water into the warning tank in the rising process of accumulated water, the pressure spring can prevent air pressure from pushing the sealing plate to move downwards to open the plain tube so as to extend the rubber rolling tube to work, namely, when the depth of the accumulated water is shallow, the warning is not carried out, and when the accumulated water is deep, the air pressure at the upper part in the warning tank pushes the sealing plate to move downwards, the pressure spring is compressed, the first magnetic block and the second magnetic block are gradually close to each other, the magnetic force is larger than the deformation force of the pressure spring, the first magnetic block and the second magnetic block are attracted to and locked with the pressure spring, the accumulated gas can enter the rubber winding pipe from the flat pipe instantly, so that the rubber winding pipe is stretched instantly, the problems that the accumulated gas cannot prompt effectively and the passing is blocked due to slow stretching are avoided, and the safety and the reliability of the device are improved.

3. The distance from the floating rod to the sliding groove is larger than the distance from the piston device to the sliding groove, so that the buoyancy driving force arm is larger than the force arm for prying the piston device, the buoyancy can be enabled to be stretched easily, and the sensitivity and the reliability of accumulated water detection of the device are improved.

In conclusion, the depth of accumulated water can be sensitively detected by utilizing the buoyancy of the accumulated water and the principle of labor-saving lever, the accumulated water can reach the function of limiting the water level and quickly acting to implement warning by the change of the air pressure in the piston and the warning tank and the limitation of the sealing plate by the first magnetic block, the second magnetic block and the pressure spring, and the device is more timely, reliable and striking.
