Abstract
The invention relates to a manhole cover loss alarming device, which mainly comprises three parts, a group of pressure switches (two or more), an explosion-proof and waterproof lamp and an alarm speaker 4. Multiple switches are arranged so that the alarm can not be switched off easily, the number of the switches for each manhole is determined according to local security conditions. The pressure switches are arranged between the manhole cover and a manhole cover gasket. When the manhole cover is in good condition, the switches are switched off, and when the manhole cover is removed, the switches are switched on and the lamp and the alarm are started simultaneously. The lamp and the alarming speaker are arranged on the manhole wall and can not be contacted easily from the ground. The light and alarm sound are transmitted out from the open mouth of the manhole, thereby not only shocking criminals but also reminding passing people against falling in. The invention has the advantages of simple structure, convenient installation, low production cost, easy popularization, easy maintenance and high safety.
Description
Technical field
The present invention relates to the warning device of lossing of well lids such as a kind of road drainage well, maintenance well, belong to town road corollary apparatus technical field.
Background technology
Buried Pipeline Network Systems is the important component part of city municipal administration infrastructure, serves as a series of people's livelihood important tasks such as sewage effluent, delivery of fuel gas, heating communication.Wherein a lot of pipelines be along urban road in provided underground, reserved a lot of well heads in order to carry out work such as pipeline maintenance, maintenance.Because some people, a large amount of well lids of lossing has caused the loss of not guilty masses' life and national wealth.So the problem of lossing of well lid more and more causes people's attention, various anti-stealing manhole covers are devised.
Summary of the invention
The present invention makes things convenient for the function of staff down-hole construction operation in addition when serving as antitheft task.
The present invention mainly contains three parts and forms one group of pressure switch (two or more) 3, anti-riot watertight light fitting 5, alert speaker 4.
Why a plurality of switches are set are for alarm can be switched off easily, the number of switches of each well head is decided on local safety case.Pressure switch 2 is satisfied with between well lid 1 and the well lid packing ring 9.Switch 2 cuts out when well lid 1 is built, and switch 2 is opened when well lid 1 is removed, and lamp 4 and alarm 3 are opened simultaneously.Light fixture 4 and alert speaker 3 are placed on the borehole wall, can not touch easily from ground.Light and alarm song send from the well head that opens wide, and frightened the offender on the one hand, have also reminded the passing masses carefully to fall on the other hand, and when the staff went into the well work, light can also play the mine lighting effect.Simple structure of the present invention, easy for installation, production cost is low, be easy to penetration and promotion, be convenient to safeguard, the security performance height.

Embodiment
A plurality of as shown in Figure 1 pressure switches 2 are satisfied with between well lid 1 and the well lid packing ring 9, and light fixture 4 and alert speaker 3 are placed on the borehole wall, can not touch easily from ground.
Make a plurality of pressure switches 2 and anti-riot watertight light fitting 4 and alert speaker 3 employings open many prosecutors formula by power lead 6 more as shown in Figure 2 and be connected, light fixture 4 and alert speaker 3 are opened simultaneously when any one pressure switch 2 is in closure state.
Claims (1)
