Description

Intelligent well lid

[ field of technology ]

The utility model relates to the technical field of well covers, in particular to an intelligent well cover.

[ background Art ]

The well cover is used for covering a road or a deep well in a home and preventing people or objects from falling carelessly. In order to ensure the use safety of the well lid, a monitoring device is generally arranged on the well lid so that alarm information can be timely generated and reported under the conditions of losing, moving and the like of the well lid.

The monitoring device of the traditional manhole cover generally adopts a gyroscope, a door magnetic switch and the like as sensing devices for identifying the state of the manhole cover (opening, closing and the like of the manhole cover), such as an intelligent manhole cover disclosed in Chinese patent application No. CN202123353778.5, wherein the gyroscope is arranged in a cavity of the manhole cover; as another example, an intelligent well lid is disclosed in the chinese patent application No. CN202121006616.1, which is to set a door magnetic switch on the well lid to realize an alarm function. Because the working environment where the well lid monitoring device is located is bad (such as high temperature, high humidity, large day and night temperature difference, past vibration of vehicles, rolling compaction, acid-base corrosion and the like) in actual working, after the device is used for a plurality of years, the magnetic field intensity of the magnetic attraction component for detecting the state of the well lid by using door magnetic induction can be weakened, and due to factors such as past vibration of road vehicles and the like, the situation that the false alarm of the state of the well lid is caused (such as that the mistaken identification well lid is opened and the alarm is reported) can be caused to a higher probability, and thus unnecessary inspection arrangement is caused. The monitoring device adopting the gyroscope as a sensing device also has the false alarm with high probability, the time from lifting up to landing of the well cover is short (usually about 0.5 seconds) because of the large interference of the road surface, and if the sensitivity of the inclination angle monitored by the gyroscope is too high, the alarm is triggered frequently; the sensitivity of the dip angle is set too low, so that the gyroscope is likely to be incapable of waking up the equipment, and the warning condition of the well lid state change is not reported correctly.

As a common supplementary scheme of the well lid monitoring device, besides adopting a gyroscope, a door magnetic switch and other sensing devices, a photosensitive device is adopted as an auxiliary sensing means, and the working principle is that when the state of the well lid is changed (opened and closed), the intensity of the ambient light of the monitoring device is also changed, so that whether the state of the well lid is actually changed can be accurately identified by measuring the intensity of the ambient light. However, although the problems of false alarm and false omission caused by the state change of the well lid can be solved to a great extent through the ambient light intensity monitoring, a certain degree of monitoring dead angle still exists, and for the area which cannot be effectively covered by the street lamp at night, the ambient light intensity of the well lid monitoring device is insufficient to form enough difference in the opening and closing states, and the problems of false alarm and false omission still exist. In view of the above problems, the present inventors have conducted intensive studies on the problems, and have produced the present utility model.

The distance measuring element 32 is used for measuring the distance between the intelligent monitoring device 3 and the signal reflecting part 5 so as to determine the state of the intelligent well cover 100 through the distance between the intelligent monitoring device 3 and the signal reflecting part 5.

According to the utility model, the Hall switch element 31 and the ranging element 32 are arranged on the base 1 of the intelligent well lid 100, and the magnet 4 matched with the Hall switch element 31 and the signal reflecting part 5 matched with the ranging element 32 are arranged on the cover body 2, so that when the intelligent well lid is specifically used, the state of the cover body 2 can be primarily judged by utilizing the matching of the Hall switch element 31 and the magnet 4, and then the state of the cover body 2 can be further judged by utilizing the matching of the ranging element 32 and the signal reflecting part 5, so that the influence caused by interference factors (such as vehicle past vibration and the like) is reduced. Compared with the existing mode of adopting a gyroscope or a door magnetic switch, the method can effectively reduce the situations of false alarm and missing alarm in travel, which is beneficial to improving the problems of unnecessary inspection caused by false alarm and potential safety hazard caused by missing alarm, and the reduction of the false alarm situation is beneficial to reducing the power consumption, so that the service life of the intelligent monitoring device 3 is prolonged; in addition, the hall switching element 31 and the distance measuring element 32 are not affected by the intensity of the ambient light, and can be better adapted to various environments.
