Abstract

The utility model discloses a device for monitoring the opening of a well cover. The device comprises a stroke switch on the wall of the well and a signal acquiring and processing device, wherein the stroke switch is connected to a resilient means, the signal acquiring and processing device acquires signals of the stroke switch and sends the signals to a monitoring center. The simple and practical stroke switch is provided for detecting the state of a well cover through a wire loop of a certain shape. The device is simple in structure and easy for construction and can monitor a well cover.

Description

The monitoring device that a kind of well lid is opened

Technical field

The utility model relates to the monitoring device that a kind of well lid is opened, and relates in particular to a kind of monitoring device that with gemel well lid is opened that is applied to.

Background technology

Along with the development of modern city, increasing electric power has adopted the underground utilities mode with the cable of communicating by letter.Convenient for maintenance and management, arranged numerous well lids.But well lid is robbed or burgled, illegally open phenomenon, happen occasionally, in case lose or illegal the unlatching, or " well is eaten the people " phenomenon occurs or have people's illegal invasion to produce and destroy equipment, cable.

Robbed or burgled in order to prevent well lid, there is the people on well lid, to be provided with pattern manhole cover lock, and make an effort anti-the opening on pick-proof of pattern manhole cover lock, thus, though receive certain effect, not enough is when in a single day well lid is pried open or be stolen, can't realize detecting and Realtime Alerts.At present a lot of well lid monitoring devices is also arranged, but mostly device is complicated, sensitivity is low, assembling is difficult.

The utility model content

The monitoring device that the utility model provides a kind of well lid to open, purpose is Real-Time Monitoring well lid state, in case there is the illegal open manhole cover of people in the very first time, to notify the related management personnel by this situation, responding in time or reparation, avoid the further generation endangered.Simultaneously, this monitoring device has solved the problems such as device is complicated, sensitivity is low, assembling is difficult.

For achieving the above object, the utility model adopts following technical scheme.

The monitoring device that a kind of well lid is opened, comprise the travel switch and the signal acquisition and processing apparatus that are arranged on the borehole wall, above described travel switch, connect an elastic device, and the signal of described signal acquisition and processing apparatus collection travel switch, and send to Surveillance center.

Described elastic device comprises spring and wire loop, and described spring one end is connected with travel switch, and the other end is connected with wire loop, and described wire loop is " ρ " shape.

Described travel switch is fixing in the enclosure, and shell has at well lid by bolts assemblies on the borehole wall of a side of hinge.

The vertical component of described wire loop inserts spring.

Described signal acquisition and processing apparatus comprises collector and main frame, and described collector gathers the signal of travel switch, and sends to main frame, sends to Surveillance center after described host process.

Above travel switch, connect wire loop by spring, wire loop can tilt under external force; Wire loop curves " ρ " shape, is beneficial to the control vergence direction, tangent with the well lid medial surface, can rotate and rotate along with well lid; This shape is not easy to block simultaneously.

Travel switch is assemblied in well lid to be had on the borehole wall of a side of hinge, and the shell level altitude will be controlled at apart from the well lid certain size, guarantees the validity of travel switch effect.

Working method of the present utility model is: well lid is when open mode, and spring is erectility, and switch is closure state; When well lid slowly closes, wire loop slowly tilts under the drive of well lid, reach certain angle, by spring, drives travel switch and disconnects; Well lid closes rear motionless, and travel switch is in off-state always; Allow there are vibrations in well lid, only otherwise just lift and can not cause the state variation of switch; In case there is the people to open (normally opening or illegal the unlatching) wire loop, can and then recover plumbness along with lifting of well lid, travel switch transfers closure state to.The variation transmit button amount of travel switch closure and off-state is to collector, by collector, the variation of signal is sent to main frame again, until send Surveillance center to, the staff grasps the state of on-the-spot well lid by Surveillance center's very first time, in case well lid is illegally opened, the further destruction to equipment such as tunnel pipelines is avoided in responding in time as far as possible.

The beneficial effects of the utility model: a kind of simple travel switch is provided, by the wire loop of definite shape, has detected the well lid state.Simple in structure, construction easily, has been played the effect of monitoring well lid.

The accompanying drawing explanation

Fig. 1 is the well lid open mode;

Fig. 2 is the well lid closed condition;

Fig. 3 is wire loop shape schematic diagram;

Fig. 4 is the detection alarm topological diagram.

In figure: 1. the borehole wall, 2. well lid, 3. wire loop, 4. spring, 5. travel switch, 6. shell, 7. bolt.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described further.

The assembling mode: wire loop 3 eccentric arm X determine according to field condition and travel switch 5 positions.Wire loop 3 and spring 4 are nested together, and wire loop 3 vertical components insert spring 4, and the inclination of wire loop 3 will be guaranteed the action of travel switch 5.Travel switch 5 is fixed in shell 6, by bolt 7, shell 6 is fixed on the borehole wall 1, the borehole wall 1 at place is the side that well lid 2 has hinge.

Working method: well lid 2 is when open mode, and spring 4 is erectilities, and switch is closure state; When well lid 2 slowly closes, wire loop 3 slowly tilts under the drive of well lid 2, reach certain angle, by spring 4, drives travel switch 5 and disconnects; The well lid 2 motionless travel switch 5 that closes is in off-state always; Well lid 2 allows to exist vibrations, only otherwise just lift and can not cause the state variation of switch; Wire loop 3 can be along with lifting of well lid 2 and then recovered plumbness in case there is the people to open (normally opening or illegal the unlatching), and travel switch 5 transfers closure state to.The variation transmit button amount of travel switch 5 closures and off-state is to collector, by collector, the variation of signal is sent to main frame again, until send Surveillance center to, the staff grasps the state of on-the-spot well lid 2 by Surveillance center's very first time, in case well lid 2 is illegally opened, the destruction to equipment such as tunnel pipelines is avoided in responding in time as far as possible.

Although above-mentioned, by reference to the accompanying drawings embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
