Problems solved by technology

[0002] The bridge is a very important part of people's daily travel life. Although large bridges account for the main part, in some remote areas or areas with limited terrain, due to economic conditions or other limiting factors, flood bridges are also included in bridge construction. Most of the current flood bridges have only very low guardrails or even no guardrails
Since most flood bridges are distributed in rural areas, people's safety awareness is weak, and safety accidents during the rainy season will increase a lot compared to the dry period, because the river water rises during the rainy season, and the river water will submerge the bridge body and even the railings. People do not pay attention The speed of the water or the depth of the water will cause a drowning accident when crossing the bridge. If the rescue is not timely, life will be endangered.

Embodiment 1

[0020] Embodiment one, adopt the overflow bridge of guardrail of the present invention, as figure 1 As shown, it includes a bridge head guardrail 1, a bridge body 2, and a bridge deck 3. The water flow 4 can overflow the bridge deck 3, and a bridge head guardrail 1 is respectively arranged at the four corners of the bridge deck 3.

[0021] Such as figure 2 , 3 , Shown in 4, the bridge head guardrail 1 is made up of guardrail column body 5 and foundation 6, and foundation 6 is fixed in the bridge body 2. On the upper part of the guardrail column body 5, an acoustic wave type water level sensor 7 is installed, which can stretch out in parallel, and is used to measure the water depth height over the bridge deck. At the lower part of the guardrail column 5, there is a grille 8, so that the water flow 4 can enter and pass through the guardrail column 5, and at the position where the grille 8 is opened, a flow sensor 9 is installed inside the guardrail column 5 for use For meas...

Embodiment 2

[0022] Embodiment two, considering the length of the flood bridge or the bending condition, such as Figure 5 As shown, according to the length of the bridge, at least one intermediate guardrail 12 can be added to the middle part of the bridge to clearly delineate the boundary of the bridge deck. The structure of middle guardrail 12 is as Figure 6 As shown, compared with the bridgehead guardrail 1, the middle guardrail 12 cancels the display screen and replaces it with a laser emitting head 11, which is symmetrical to the position of the laser emitting head on its back, that is, four laser emitting heads 11 are arranged on the middle guardrail 12. It is used for the docking with the laser transmitter head of the bridgehead guardrail.

[0023] The schematic circuit diagram of the electronic system in the flood bridge guardrail that the present invention proposes is as follows Figure 7 As shown, the control center of the electronic system uses the AT89C52 single-chip microco...

Abstract

The invention relates to a submersible bridge and a water level and flow velocity detecting method thereof. The submersible bridge comprises bridgehead guardrails, a bridge body and a bridge surface. Water can overflow the bridge surface; the four corners of bridge surface are respectively with one of the bridgehead guardrails; every bridgehead guardrail is composed of a guardrail column and a base, wherein the base is fixed into the bridge body, the upper part of the guardrail column is provided with a water level sensor, and during water level detection, the water level sensor extends in parallel; the lower part of the guardrail column is provided with a retainer, where a flow velocity sensor is arranged inside the guardrail column; one side of the middle of the guardrail column, which faces towards the bank, is provided with a display screen, and the back surface of the display screen is provided with two laser emitters which are vertically arranged. By means of the functional guardrails arranged on the submersible bridge, pedestrians crossing a driver can obtain certain safety instructions, so that safety of vehicles and pedestrians can be guaranteed.
