Push-and-block type electrical control anti-theft well lid

Abstract

The invention discloses a push-and-block type electrical control anti-theft well lid comprising a well lid and a well frame, wherein the well lid is horizontally placed on the well frame; a motor is fixed at one end of the well lid; the output shaft of the motor is connected with a chuck driving device; a fixed plunger is mounted at the other end of the well lid; a movable plunger is axially mounted on a chuck; a shift hole is formed in the well lid in a corresponding position below the movable plunger; the chuck surface of the chuck of the chuck driving device is formed by two step surfaces with different thicknesses; and a lock plunger hole corresponding to the movable plunger is formed in the well frame. All the electronic parts and the electromechanical transmission part of the push-and-block type electrical control anti-theft well lid are sealed integrally, so as to solve the problems in preventing water, sand and damage. No component of a lock body control part is positioned above the well lid, so as to achieve good anti-theft and damage prevention effects. The in-out expansion and contraction distances of a lock plunger are controlled by a rotating disc, so that the locking control of the well lid is realized, and the use is reliable and simple.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a push-and-shift electronically controlled anti-theft manhole cover. Background technique [0002] At present, public resources such as urban communication and energy are connected to suppliers and users through underground network pipelines. The management and maintenance of these underground pipeline network resources are mainly realized through manholes. Underground pipelines provide us with an efficient resource transportation method. But it also brought a lot of crisis to the city; manhole covers were stolen and man-made damage left a big hole in the road surface, which greatly affected traffic safety and caused immeasurable losses. At present, a small number of electronically controlled locks in use can realize the anti-theft function of the manhole cover. The control mechanism uses a magnetic suction mechanism to control the tongue to block the movement of the lock bolt to...

[0002] At present, public resources such as urban communication and energy are connected to suppliers and users through underground network pipelines. The management and maintenance of these underground pipeline network resources are mainly realized through manholes. Underground pipelines provide us with an efficient resource transportation method. But it also brought a lot of crisis to the city; manhole covers were stolen and man-made damage left a big hole on the road, which greatly affected traffic safety and caused immeasurable losses

At present, a small number of electronically controlled locks in use can realize the anti-theft function of the manhole cover. The control mechanism uses a magnetic suction mechanism to control the tongue to block the movement of the lock bolt to achieve the locking function. Due to the scattered components, the control force of this structure is not strong, and it cannot be well waterproof. Anti-sand and anti-corrosion, easy to break, not very good protection in fact
