Embodiment 1

[0029] Example 1: Electromagnetic anti-theft lock manhole cover controlled by power supply

[0030] From Figure 1-7 As can be seen in the figure, the present invention is made up of well cover 4, well seat 5. Two inward cylindrical pins 9 are arranged on the inwall of well seat 5 circumferences, and these cylindrical pins 9 are placed horizontally, and one end is fixed on the inwall of well seat 5, and the other end faces the side wall of well cover 4. It also has an electromagnet 2, the electromagnet 2 is outside the inner wall circumference of the well base 5, and there is a horizontal hole on the inner wall of the well base 5 to allow the dead bolt 3 of the electromagnet 2 to pass through, and there are two or three pin holes on the circumferential side of the well cover 4 8. The positions of the pin holes 8 correspond to the cylindrical pin 9 and the dead bolt 3 of the electromagnet 2 respectively, and the diameter and length of the pin hole 8 match the cylindrical pin 9...

Embodiment 2

[0031] Example 2: Anti-theft manhole cover controlled by power supply and coding

[0032] Figure 1-7 It also shows that the anti-theft well cover also has an electrical box 1, the electrical box 1 is fixed on the outside of the inner wall of the well base 5, the upper and lower surfaces of the box are respectively flush with the upper and lower end faces of the well base 5, and the electromagnet 2 is installed in the electrical box 1 Inside, there is also an electromagnet connection control device in the electrical box 1, the external power supply jack 10 of the electromagnet 2 and the signal input jack 11 of the control device are fixed on the well base 5, and one end of the control device is connected to the electromagnet 2. The other end is connected with the external power supply jack 10 and the signal input jack 11. The lower surface of the electrical box 1 is an electrical box cover 6, which can be opened for installation and maintenance of the electromagnet 2 and the ...

Embodiment 3

[0040] Embodiment 3: Anti-theft manhole cover controlled by power supply and wireless transmission code

[0041] The decoding controller is a hand-held remote control with a signal transmitting circuit. The signal transmitting circuit is added at the last stage of the signal output part, and the signal receiving part is added at the front stage of the signal receiving part. There is no signal input jack on the well base, only the power plug The signal input part can be divided into two separate devices, the power supply part and the signal transmitting part. When in use, insert the power plug into the power jack on the well base, and then send signals through the hand-held remote control to control the attraction of the electromagnet. The signal transmitting circuit and the signal receiving circuit added in this embodiment are mature prior art and can be realized completely, and the design of this structure should also be within the scope of protection of the present invention...

Abstract

The invention relates to a method for guarding the well cover and relative anti-theft well cover, belonging to city fitting device technique, while the invention has simple structure, and easy operation. The invention comprises a well cover and a well base, wherein, the well base comprises a horizontal well base ring and an inner wall vertical to the inner circumference of well base ring. It is characterized in that: the well cover and the well base utilize two-point or three-point connection of cylinder pins; the well base has electromagnetic anti-theft lock which has at least on cylinder pin as bolt; it uses electromagnetic iron to connect the control device to control the movement of said bolt; the external power has a decode controller; and the electromagnetic anti-theft lock can start the movement of bolt when the decode controller is connected and its encode signal meets the anti-theft code. In said invention, the power control signal is encode signal which can solve the anti-theft problem.

Description

technical field [0001] The invention relates to an anti-theft well cover used in an anti-theft method for well covers such as road drainage wells and maintenance wells, and belongs to the technical field of road matching devices. Background technique [0002] The underground pipeline system is an important part of urban infrastructure, responsible for discharging sewage, transporting gas, laying underground communication cables and other tasks. Wherein many pipelines will be laid underground along urban roads. In order to carry out work such as pipeline dredging and maintenance, many shafts are set above the pipelines, which are covered by openable manhole covers. The number of manhole covers is large and the distribution area is wide. However, the loss of pipeline manhole covers in cities is serious at present, which not only causes great economic losses to the country, but also exposes well holes that often cause damage to passing vehicles and pedestrians after road manhol...
