Description

Flood plugging device with emergent alarm function

Technical Field

The invention relates to the field of flood plugging devices, in particular to a flood plugging device with an emergency alarm function.

Background

Water bodies such as rivers, oceans, lakes and the like rise to exceed a certain water level, threaten the safety of relevant areas, even cause water flow of disasters, and in areas which are close to oceans and have developed water systems, the water level of river water is easy to rise in rainy seasons due to seasonal strong rainfall, flood is induced, and irreversible damage is caused to the life and property safety of people in river water basin areas.

When the water level rises due to the concentrated heavy rain in the rain season process of river and river basin, special people are generally required to be organized to carry out flood fighting activities, the flood fighting activities are mostly temporary flood fighting facilities, such flood fighting facilities mostly take plugging facilities as the main, the terrains of river banks and dams are raised by the aid of the plugging facilities such as sand bags and plugging plates, the liquid level is prevented from rising to directly submerge the river banks and the dams, and waterlogging is formed at the lower part of the terrains.

However, in the river and river basin, the water level of the river and river water rises suddenly due to too long time in rainy season or too concentrated rainfall, which is very easy to damage the sand bags and the plugging plates, even directly causes the phenomenon of collapse of the plugging facilities, and the collapse phenomenon usually occurs suddenly, only a short reaction time is left for flood fighting personnel, and the work difficulty of the flood fighting personnel is greatly increased usually due to the sudden occurrence of the collapse phenomenon, even the life health safety of the flood fighting personnel is affected.

Disclosure of Invention

1. Technical problem to be solved

Aiming at the problems in the prior art, the invention aims to provide a flood plugging device with an emergency alarm function, which can send out early warning information in time before a flood-fighting plugging facility collapses, remind flood fighting personnel of strengthening in time, reserve sufficient reaction time for the flood fighting personnel, reduce the difficulty of flood fighting work and reduce the life health and safety of the flood fighting personnel.

2. Technical scheme

In order to solve the above problems, the present invention adopts the following technical solutions.

A flood plugging device with an emergency alarm function comprises a fixed base plate, wherein a pair of side fixing plates is fixedly connected to the upper end of the fixed base plate, a plugging plate is hinged to the upper end of the fixed base plate and located between the pair of side fixing plates, mutually matched limiting sliding grooves are formed in the mutually close ends of the two side fixing plates, each limiting sliding groove comprises a linear part and a bent part, a limiting rod matched with the limiting sliding groove is fixedly connected between the side walls of the limiting sliding grooves, a limiting sliding block matched with the limiting sliding block is connected in the limiting sliding grooves in a sliding mode, the limiting sliding block penetrates through the limiting sliding block and slides in the limiting sliding groove along the direction of the limiting rod under the limitation of the limiting rod, connecting rotating shafts are connected between the plugging plate and the pair of limiting sliding blocks, and a fixing cylinder is fixedly connected between the limiting sliding block and the side walls of the limiting sliding grooves, the fixed cylinder cup joints the outside at the gag lever post, spacing slider and fixed cylinder all are located the straight line portion of spacing spout at flood plugging device normal during operation, evenly dig on the fixed cylinder has a plurality of prefabricated breachs, and is a plurality of prefabricated breach all runs through the lateral wall of fixed cylinder, can realize in time sending early warning information before anti-flood shutoff facility collapses, reminds anti-flood personnel in time to consolidate, reserves for anti-flood personnel sufficient reaction time, reduces the degree of difficulty of anti-flood work, reduces anti-flood personnel's life health safety.

Further, a flood plugging device's early warning system with emergent alarm function, treat in the plugging device and have processing terminal and energy memory, the power supply line has been laid in the solid fixed cylinder, and the power supply line walks around a prefabricated breach and form complete loop in the solid fixed cylinder, through power supply line electric connection between processing terminal and the energy memory, processing terminal in the plugging device signal is connected with thing networking module, signal device signal connection has mobile terminal, and processing terminal can last to send operating signal to mobile terminal through thing networking module at the in-process that the plugging device normally worked, and when the plugging plate took place under the flood effect at the plugging device and the plugging plate leans forward, the fracture of solid fixed cylinder can tear the power supply line simultaneously off, cuts off the connection between processing terminal and the energy memory, handles the terminal and stops to send working signal, and flood fighting personnel need in time go to the installation place of plugging plate to the plugging device when mobile terminal can's unable received working signal And (5) reinforcing.
