Description

Technical Field

[0001] The invention relates to the technical field of flood prevention, and in particular to an urban flood prevention early warning device. Background Art

[0002] In recent years, extreme weather has occurred more and more frequently. Existing technologies rely on technologies such as the Internet of Things and wireless communications, integrating hardware equipment such as water level sensors, rain gauges, communication equipment, and telemetry terminals to automatically collect and monitor local rainfall, river / low-lying flood-prone area water levels, and on-site images / videos and other hydrological data, and report them through 5G / 4G, LORA, wifi, Beidou and other communication networks. Through a visual smart water conservancy cloud platform, the real-time situation of water accumulation can be viewed remotely, and 24-hour monitoring of reservoirs, rivers, drainage manhole covers, flood-prone areas and other locations can be achieved without human supervision. Reports can be made to relevant departments or personnel in a timely manner through WeChat, text messages, telephone calls, etc. According to the early warning messages, early warning plans and preventive measures can be formulated in advance to reduce the losses and impacts caused by disasters. For example, the patent with application number CN202020265492.8 discloses a flood prevention warning device for monitoring water level stability, including a server, a relay device, a node device and a sensor. The sensor detects the water level information and sends it to the node device. The node device determines whether the received water level information is at the warning level through processing. If it reaches the warning level, the warning level information is sent to the relay device through the communication module, and then transmitted to the server through the relay device. The function of automatic monitoring of the water level is realized. When the water level exceeds the warning level, the server sends the automatic push information of the corresponding control measures to the user end, and realizes the remote monitoring function of the flood prevention warning of important equipment. When any flood disaster occurs, the information is quickly sent to the server through the relay device to obtain the actual flood information in time, which is of great significance for flood prevention warning. At the same time, the patent with application number CN202320496198.1 discloses a flood prevention monitoring device, including a solar panel, a laser water level meter and a laser ranging reflective device. The laser water level meter is provided with a box body, an integrated lithium battery is provided at the front end of the upper part of the box body, a remote terminal control system is provided at the rear of the integrated lithium battery, an antenna is provided at the top of the remote terminal control system, a laser controller is provided in the middle of the box body, and a laser water level probe is provided in the lower part of the box body. The various components are connected by cables, and the solar panel is fixedly connected to the outer side of the box body; a fixing device is connected to the rear side of the box body, and the fixing device is fixedly connected to the wall or support rod; a laser ranging reflective device is fixedly provided on the ground below the laser water level probe. Placing the laser ranging reflective device on the ground below the laser water level probe can prevent external factors from damaging or deforming it, changing its straight state and affecting the monitoring effect of the laser beam. However, the following problems still exist:

[0003] (1) The drainage ditch cover is not equipped with a protective structure, which often causes blockage, objects falling into the ditch, or children's legs getting stuck. Blockage also makes drainage difficult and monitoring difficult.

[0004] (2) When the rainfall is too heavy, the water accumulates deeply and there are no warning structures, posing a safety hazard. Summary of the invention
