Description

The horizontal naked mouthful of automatic attention device of well

(1) technical field

The utility model relates to a kind of safety device, specifically a kind of safety indicating device that is used for well head.

(2) background technology

At various underground installations such as power supply, heating, air feed, plumbing, septic tank, communication, oil pipelines, to be provided with all that some are used to observe on ground, the well of maintenance etc.In the city, these wells are positioned on the street mostly.In order to guarantee vehicle and pedestrian's safety, the anti-manhole cover of being made up of walling crib and well lid to be set all at the well head place.Present anti-manhole cover only covers its function of safety protection of competence exertion under the condition on the walling crib in good condition at well lid.In actual use, well lid is former thereby cause that well lid and walling crib break away from, well head exposes because rolled breakage etc. by lawless person theft, vehicle through regular meeting.These naked mouthful of untimely maintenance process of well can have been brought great hidden danger to urban traffic safety.Personnel or vehicle are arranged often because of falling into naked mouthful well, cause casualties or the report of property loss occurs.Though existing multiple well lid with anti-theft feature occurs, and can not stop the appearance of naked mouthful of well fully.Needs to well in facility check or when keeping in repair, people must open well lid, this normal operation, in order to give pedestrian and vehicle with caution, special-purpose warning mark all will be set near the well head of opening, and these warning marks need carry at any time, the on-the-spot installation, operate cumbersome.

(3) summary of the invention

The purpose of this utility model is to provide a kind of alarm signal, simple in structure, easy to use, horizontal naked mouthful of automatic attention device of well that reliability is high of can sending automatically after well lid is opened.

The purpose of this utility model is achieved in that it comprises caution mark post and axle, and the caution mark post is rotatably installed on the axle, and the two ends of axle are fixed on well body or the walling crib, and an end of caution mark post is connected with weight.

The utility model can also comprise some architectural features like this:

1, the end that does not connect weight at the caution mark post is equipped with warning sign.

2, the sign board that has well on the described warning sign.

3, the sign board of described well is printed on the warning sign.

4, the sign board of described well hangs on the warning sign.

5, scribble eye-catching caution color on the described caution mark post.

6, be provided with bearing between caution mark post and the axle.

Advantage of the present utility model is: when well lid covered on well head, the caution mark post was horizontal in well, without any exposed parts, can not have any impact to the current of pedestrian and vehicle on the road surface.No matter be normally to open well lid to overhaul or safeguard that still because well lid is stolen or damaged, as long as well lid separates with well head, the caution mark post will sway under the effect of weight, an end is downward, and the other end rises and stretches out well head.The caution mark post that stretches out well head plays the effect of sending alarm signal to passer-by or vehicle.Device of the present utility model is without any need for power, as long as well lid breaks away from well head, the caution mark post just can stretch out well head automatically, can send alarm signal in the very first time.Its simple in structure, easy realization and need not carrying with car.After device of the present utility model is applied, can thoroughly eliminate the well danger that falls of the pedestrian, the vehicle that cause owing to reasons such as well lid is lost, breakages.
