Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waterlogging prevention monitoring, in particular to a waterlogging prevention monitoring device for a riverside sunken zone and a use method thereof. BACKGROUND

[0002] The riverside sunken zone is generally low in overall terrain, and sudden rainwater increase often leads to flood disasters, which seriously threaten people's life and property safety.

[0003] There are many types of devices for monitoring the water level. The traditional water level monitor monitors the water level by the monitoring probe at the end in contact with the water surface. However, the device is set up in a remote section, and it is inconvenient to control the height position of the probe at any time to facilitate the exploration of the water level height. The advanced ultrasonic water level meter is used, but it is easily affected by the shielding of the dense vegetation and rolling stones below, which affects the monitored data, and thus cannot meet the use requirement.

[0004] Therefore, in view of the above-mentioned problem that the existing water level monitoring device cannot flexibly adjust the height of the monitoring probe to facilitate the exploration of the specific height of the existing water level, and the use of the ultrasonic water level meter is also easily affected by the shielding of the object below, and thus cannot obtain accurate water level data, affecting the monitoring result, and thus cannot meet the use requirement, a waterlogging prevention monitoring device for a riverside sunken zone can be designed. The interior is isolated from the outside by setting three arc-shaped transparent glass plates to avoid the influence of external objects on the use of the waterproof and turnable camera and the monitoring probe body. The monitoring probe body and the waterproof and turnable camera are driven to rise and fall synchronously by controlling the lifting block to rise and fall, and the change of the water level is adaptively adjusted and monitored, and the surrounding is monitored.

[0005] Therefore, based on the rich experience in design, development and actual production in the related industry for many years, the present applicant studies and improves the existing structure and defects, provides a waterlogging prevention monitoring device for a riverside sunken zone and a use method thereof, so as to achieve a more practical purpose.
