Fully-automatic intelligent manhole cover lock with opening and closing functions, manhole cover and opening and closing control method

Abstract

The invention discloses a fully-automatic intelligent manhole cover lock with opening and closing functions, a manhole cover and an opening and closing control method, and belongs to the technical field of intelligent control of manhole covers. The fully-automatic intelligent manhole cover lock structurally comprises a lock body assembly, a drive assembly and a control assembly; the lock body assembly comprises multiple lock body units distributed in the circumferential direction of a cover body; each lock body unit comprises a lockpin, a guiding tube and a reset spring, the lockpin is mountedin the guiding tube in a sliding manner, and the reset spring is arranged on the lockpin in the guiding tube in a sleeving manner and drives the lockpin to extend out of the guiding tube; the drive assembly comprises a drive motor, a turnplate and a connecting strip, the turnplate is mounted on an output shaft of the drive motor, and two ends of the connecting strip are connected with the lockpinand the turnplate respectively; the control assembly is connected with the drive motor and used for receiving an external control command to control the drive motor to rotate forwards or reversely. The whole technical scheme has the advantages of being simple in structure, low in cost, safe and reliable to open and close, multifunctional and high in intelligent level and the like.

Description

technical field [0001] The invention mainly relates to the technical field of electrical control, in particular to a fully automatic intelligent manhole cover lock with an opening and closing function, a manhole cover and an opening and closing control method. Background technique [0002] The city's water supply, drainage, communication, electricity, and gas are the basic public facilities that guarantee the normal life of citizens. The underground pipe networks for water supply, drainage, communication, electricity, and gas are criss-crossing and spread across every corner of the city. The expansion of the underground pipe network will also expand accordingly. As the connection channel between the underground pipe network and the ground, the inspection shaft provides a convenient maintenance entrance and exit channel for the basic public facilities in the underground pipe network. At the same time, there are many uncontrollable safety factors in inspection wells, which ma...

Problems solved by technology

[0003] 1) Most of the existing pipeline manhole covers do not have a locking structure, even if there is a simple mechanical locking structure, it is very easy to open;

[0004] 2) The so-called smart manhole cover locks on the market have complex structures and extremely poor protection performance. Under the harsh environment of pipelines, their functions and life cannot be guaranteed, and they cannot meet the monitoring requirements at all;

[0005] 3) The so-called smart manhole cover locks on the market are semi-automatic locks, which need to be opened and closed and equipped with electronic keys, and manual operation of the open and close locks is required. The operation of the on-site staff is complicated and time-consuming. forget to lock

[0006] 4) The manufacturing cost of the so-called smart manhole cover locks in the market is high, which brings extremely high financial budget for mass application, which hinders the rapid and widespread application of electronic manhole cover locks
