Problems solved by technology

This kind of manhole cover has the following disadvantages: on the one hand, when the manhole cover is washed away, because it is in the water, this positioning system can not make people find the manhole cover quickly, which not only consumes time and effort but also delays the progress of emergency repair; Warning function, easy to cause safety accidents, especially at night

Embodiment 1

[0023] Such as figure 1 Shown: a new type of anti-movement safety manhole cover, including a disc-shaped manhole cover body 1 matching the wellhead 4, and several prefabricated concrete fixing piles 2 installed below the surface of the wellhead 4 side, the upper surface of the fixing piles 2 An electromagnetic chuck 21 is embedded; the side of the well cover body 1 is fixedly connected with a well lug 11 corresponding to the position of the electromagnetic chuck 21; a pressure sensor 12 is installed on the bottom surface of the well cover body; 21 connections.

[0024] The working process of the present invention is that when there are too many heavy rains or floods, the water level in the well rises to a certain height, and its impact force on the bottom surface of the well cover body 1 is also increasing. When the impact force reaches the gravity of the well cover body 1, it passes through the well cover body. 1 The pressure sensor 12 at the bottom senses, and the electroma...

Embodiment 2

[0027] This embodiment is further optimized on the basis of Embodiment 1. Specifically: the upper surface of the fixed pile 2 is embedded with a warning box 22 opened by the control unit 3, and a warning balloon 221 is housed in the warning box 22. , the warning balloon 221 is wound and placed in the warning box 22 through the connecting wire 222 .

[0028] In this embodiment, the warning box 22 can be activated when the well cover body 1 drifts away accidentally, so that the warning balloon 221 inside can float out, and the exposed wellhead 4 can be visually marked. The warning balloons 221 of this embodiment are visually visible, and a plurality of warning balloons 221 can surround the wellhead by installing a plurality of fixing piles 2 and warning boxes 22 . The warning balloon 221 of the present embodiment can adopt the filled small balloon, and its size is equivalent to the size of the fist of an ordinary adult. For getting rid of the flowing water that enters warning b...

Embodiment 3

[0033] In this embodiment, on the basis of Embodiment 2, a suspension box 13 opened by the control unit 3 is embedded in the surface of the well cover body 1, and the suspension box 13 is equipped with a GPS positioning system, a gyroscope sensor and a suspension board; The surface of the board is coated with waterproof luminous powder.

[0034] In this embodiment, when the well cover body 1 is about to float away, the movement angle of the well cover body 1 is detected by the gyro sensor, and when the set value is reached, the signal is transmitted to the control unit 3, and the suspension box 13 is opened by the control unit 3 (in this embodiment The suspension box 13 controlled by the control unit 3 and the warning box 22 in the embodiment 2 are opened synchronously at this time), so that the suspension board coated with waterproof luminous powder floats on the water surface, so that the well cover body 1 floats away and is convenient for people to recycle. . The connectio...

Abstract

The invention provides a manhole cover, and particularly relates to a safety manhole cover capable of being prevented from being flown away by water flow and having a safety warning effect. The safetymanhole cover comprises a disc-shaped manhole cover body matched with a wellhead and a plurality of precast concrete fixing piles installed below the earth surface and on the wellhead side surface. An electromagnetic chuck is embedded in the upper surface of each fixing pile; well lugs corresponding to the electromagnetic chucks in position are fixedly connected to the side face of the manhole cover body; a pressure sensor is installed on the bottom face of the manhole cover body; the pressure sensor is connected with the electromagnetic chucks through control units; and warning boxes openedby the control units are embedded in the upper surfaces of the fixing piles, warning balloons are installed in the warning boxes, and the warning balloons are wound and placed in the warning boxes through connecting wires. By means of the safety manhole cover, the manhole cover can be effectively prevented from being washed away by the water flow through the suction force of the electromagnetic chucks, the warning boxes are started when the manhole cover is accidentally washed away, the exposed wellhead is marked, and coming and going people can be prevented from falling into a well.

Description

technical field [0001] The invention relates to a well cover, in particular to a safety well cover capable of preventing water flow from washing away and having a safety warning effect. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. Especially in modern cities, with the improvement of municipal facilities and the development of road traffic, more and more manhole covers have appeared, so the safety performance of manhole covers has received more and more attention, and more people have studied in this field . [0003] Among the many safety accidents of manhole covers, the accidents in which manhole covers drift away due to heavy rain and floods, causing people to accidentally fall into them are particularly serious. Most of the manhole covers on the market are realized by adding safety locks in terms of safety. The safety effect is average, especially in the face of natural disasters su...
