Water-flushing-preventing sewer cover plate

Abstract

The invention provides a water-flushing-preventing sewer cover plate. The water-flushing-preventing sewer cover plate comprises a cover plate body, a sensor, a buzzer and a hook, wherein the sensor, the buzzer and the hook are successively arranged on the cover plate body; the hook of the cover plate body is connected with a rope of which one end is fixed to a sewer, so that the cover plate can beopened at a position which is distant from a sewer opening by a certain distance; the buzzer is started, the cover plate body is placed on the sewer opening, if the cover plate body is flushed away by flood, the movement distance of the cover plate body is limited due to the fact that the rope is connected with the cover plate body, moreover, a contact of the sensor arranged on the cover plate body extends and resets, the sensor sends out signals, the buzzer sends out alarming sound to warn passing crowd to pay attention to the sewer opening, and the circumstance that people drop into the sewer to cause personnel loss is avoided; and the sensor and the buzzer are waterproof, and thus, the circumstance that the sensor and the buzzer fail when meeting water. The water-flushing-preventing sewer cover plate is simple in structure and convenient to use, and the cost can be saved effectively.

Description

technical field [0001] The invention relates to the technical field of sewer cover plates, in particular to a waterproof flush sewer cover plate. Background technique [0002] The sewer cover is a municipal engineering equipment laid on the road, which represents the integrity of the road to a certain extent. In the prior art, a light-emitting device is installed on the sewer cover to protect the sewer manhole cover, which is complicated to manufacture and relatively expensive to use, and the cover is installed on the cover after it is washed away by the flood when it rains continuously. All kinds of light-emitting devices can't reach the warning effect, and the ordinary sewer cover will also be washed out from the wellhead when it rains continuously, which will also cause safety hazards. [0003] Therefore, in view of the above-mentioned shortcoming of the sewer cover, it is necessary to further develop the technology of the sewer cover. Contents of the invention [000...
