Description

Technical Field

[0001] The utility model relates to the field of urban disaster analysis, and in particular to a meteorological risk analysis and early warning device for urban waterlogging disasters. Background Art

[0002] Urban waterlogging refers to the phenomenon that waterlogging disasters occur in cities due to heavy rainfall or continuous rainfall that exceeds the city's drainage capacity. The objective reasons for urban waterlogging are high rainfall intensity and concentrated range. The precipitation is greater than the drainage capacity of urban drainage pipes, resulting in overflow of accumulated water and thus urban floods. In order to prevent urban waterlogging from causing harm to the city, urban waterlogging early warning devices are often set up to detect various drainage points in the city. When the urban water level is abnormal, the water level situation needs to be transmitted to the meteorological department for analysis and processing.

[0003] A Chinese patent discloses a meteorological risk analysis and early warning device for urban waterlogging disasters (authorization announcement number CN215954468U). This patented technology can solve the problems that existing meteorological risk analysis and early warning devices for urban waterlogging disasters mostly use sensors for detection during use. Since the sensors are too sensitive, false early warnings may occur, causing the control center to make wrong judgments. In addition, the early warning devices mostly use spherical floats, which will float violently when the water level rises, resulting in intermittent early warnings of the early warning devices and unclear warning effects.

[0004] The existing early warning devices cannot send information to the relevant departments in time when a situation occurs, resulting in slow processing speed. In addition, the early warning devices have poor stability during installation, which makes them prone to the risk of tipping over. In addition, the real-time water level information cannot be transmitted and processed in time, resulting in the problem that remote personnel cannot analyze and process the data.

Specific embodiments

[0020] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0021] Please refer to Figures 1 to 7 , in this embodiment, a meteorological risk analysis and early warning device for urban waterlogging disasters is provided, including a sewer pipe 1 and a fixed rod 2. The sewer pipe 1 is arranged at the bottom of the ground. A manhole cover is installed on the upper end surface of the sewer pipe 1. A fixed rod 2 is inserted and fixed on the outer side wall of the manhole cover. A chassis is installed on the upper end surface of the fixed rod 2. A water level detector 11 is installed on the upper end surface of the chassis. A plurality of water level sensors 12 are installed on the outer side wall of the fixed rod 2 from top to bottom. The water level sensors 12 are electrically connected to the water level detector 11. A signal transmitter 13 is installed on the upper end surface of the water level detector 11. A plurality of first alarms 14 are installed on the upper end surface of the chassis along its circumferential direction. The first alarms 14 are electrically connected to the water level detector 11. During operation, the water level sensors 12 monitor the water level in the sewer pipe 1. When the water level continuously rises and a waterlogging phenomenon occurs, the water level detector 11 receives the water level information and sends the information to the remote center through the signal transmitter 13, so that the staff can timely handle according to the urban waterlogging situation and avoid further economic losses. The use of multiple water sensor structures facilitates the staff to understand the rising situation of the water level in a timely manner and thus make analysis and processing.

[0022] The upper end surface of the fixed rod 2 is installed with a support rod 15 in a plug-in manner. The upper end surface of the support rod 15 is installed with a chassis. The outer side wall of the fixed rod 2 is installed with a bottom column. The bottom column and the support rod 15 are connected by a limit bolt 16. The outer side wall of the support rod 15 is installed with a connecting plate 17 in a sliding fit manner. The bottom of the connecting plate 17 is installed with a spring rod 18. The bottom of the spring rod 18 is installed with a plug rod. The upper end surface of the limit bolt 16 is provided with a card slot matched with it. Above the connecting plate 17 is arranged a fixing plate 19. The bottom of the fixing plate 19 is embedded with a pressure sensor 21. The upper end surface of the fixing plate 19 is installed with a second alarm 22. The bottom of the chassis is installed with a control panel. The control panel is electrically connected with the pressure sensor 21. During operation, rotate and remove the limit bolt 16 to facilitate the removal of the support rod 15, so as to perform maintenance on the water level detector 11. There is no need for personnel to climb to a high place for maintenance, improving the safety performance of the operation. The spring rod 18 drives the plug rod to move downward, so as to perform a limit treatment on the limit bolt 16, avoiding the rotation and falling off of the limit bolt 16 and the risk of the support rod 15 tipping over. When the limit bolt 16 rotates upward, it drives the connecting plate 17 to move upward, pressing the pressure sensor 21. The control panel is programmed with a PLC program, so as to transmit the pressure signal to the control panel and control the second alarm 22 to alarm, reminding the surrounding people to stay away from here to avoid the support rod 15 tipping over and injuring passers-by.

[0023] The outer side wall of the support rod 15 is installed with an arc-shaped frame. The outer side wall of the arc-shaped frame is installed with a plurality of photovoltaic panels 23 along its circumferential direction. During operation, the structure of the photovoltaic panels 23 is adopted, so as to be able to supply power to the water level detector 11, which is energy-saving and environment-friendly.

[0024] The outer side wall of the bottom column is installed with a plurality of square plates along its circumferential direction. The bottom of the square plate is installed with a limit pin 24. During operation, the limit pin 24 is inserted and fixed on the ground, improving the ground gripping ability of the fixed rod 2 and the overall stability of the device.

[0025] During specific operation, the water level sensor 12 monitors the water level in the sewer pipe 1. When the water level continuously rises and causes an internal waterlogging phenomenon, the water level detector 11 receives the water level information and sends the information to the remote center through the signal transmitter 13, enabling the staff to process it in time according to the urban internal waterlogging situation and avoiding further economic losses.
