Problems solved by technology

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 manhole covers are lost, directly threatening the safety of people's lives and property. The loss of manhole covers has already become a public nuisance in the city

Embodiment 1

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

[0030] From Figure 1-7 It can be seen that the present invention consists of a well cover 4 and a well seat 5. There are two inward cylindrical pins 9 on the inner wall of the well base 5. These cylindrical pins 9 are placed horizontally, one end is fixed on the inner wall of the well base 5, and the other end faces the side wall of the well cover 4. It also has an electromagnet 2. The electromagnet 2 is outside the circumference of the inner wall of the well base 5. There are horizontal holes on the inner wall of the well base 5 for the bolt 3 of the electromagnet 2 to pass through, and the circumferential side of the manhole cover 4 has two or three pin holes 8. The position of the pin hole 8 corresponds to the cylindrical pin 9 and the bolt 3 of the electromagnet 2 respectively, and the diameter and length of the pin hole 8 match the cylindrical pin 9 and the bolt 3 respectively. The po...

Embodiment 2

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

[0032] Figure 1-7 It also shows that the anti-theft manhole 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 body are flush with the upper and lower end surfaces of the well base 5 respectively. The electromagnet 2 is installed in the electrical box 1. Inside, there is an electromagnet switch-on 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 the electrical box cover 6, after opening, the electromagnet 2 and the control device circuit board 7 can be install...

Embodiment 3

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

[0041] The decoder controller is a handheld remote control with a signal transmitting circuit. The signal transmitting circuit is added to the last stage of the signal output part, and the signal receiving part is added to the front stage of the signal receiving part. There is no longer a signal input jack on the well seat, only the power plug Hole, the signal input part can be divided into two separate devices, the power part and the signal transmitting part. When in use, insert the power plug into the power jack on the well base, and then transmit a signal through the handheld remote control to control the attraction of the electromagnet. The signal transmitting circuit and the signal receiving circuit added in this embodiment are mature existing technologies and can be fully realized, and the design of this structure should also be within the protection scope of the present...

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 manhole cover used in an anti-theft method for road drainage wells, maintenance wells, etc., and belongs to the technical field of road matching devices. Background technique [0002] The underground pipeline system is an important part of the urban infrastructure, which is responsible for the discharge of sewage, the transportation of gas, and the laying of underground communication cables. Many of the pipelines need to be laid underground along urban roads. In order to carry out the dredging and maintenance of the pipelines, many vertical shafts are set up above the pipelines, which are covered by manhole covers that can be opened. There are a large number of manhole covers and a wide distribution area. However, the current serious loss of pipeline manhole covers in cities has not only caused major economic losses to the country, but also after the loss of road manhole covers, the exposed manholes often cause injurie...
