Description

Safe, theft-resistant manholes and manhole covers

technical field

The utility model relates to a safe and anti-theft inspection shaft and an inspection shaft cover.

Background technique

Inspection wells and inspection well covers are common on roads and streets in cities, and are an important link in municipal construction. But the stolen situation of manhole cover often takes place, has brought many dangers thus. After the manhole cover is stolen, it is very easy to cause pedestrians and various vehicles to drop the injury accident of the manhole, especially at night, the stolen manhole cover is more harmful, which greatly threatens personal and property safety.

Contents of the invention

The technical problem to be solved by the utility model is to provide a safe and anti-theft inspection shaft and inspection shaft cover, which can prevent the inspection shaft cover from being stolen, and effectively prevent pedestrians or various vehicles from falling into the inspection shaft after the inspection shaft cover is stolen, thus protecting the human body. and property safety.

In order to solve the above-mentioned technical problems, the safe and anti-theft inspection shaft and inspection shaft cover of the utility model include the inspection shaft and the inspection shaft cover covering the inspection shaft, and also include a signal transmitter, a signal receiver, two power supplies and two sound and light alarms, The two power supplies and the two acousto-optic alarms are respectively arranged on the edge of the inspection well and in the cover of the inspection well, the acousto-optic alarm is powered by the power supply, the signal transmitter is arranged on the edge of the inspection well and is controlled by the device. The power supply is supplied by the power supply at the edge of the inspection shaft, the output of the signal transmitter is connected to the sound and light alarm device located at the edge of the inspection shaft, the signal receiver is arranged in the inspection shaft cover and powered by the power supply arranged in the inspection shaft cover, The output of the signal receiver is connected to the acousto-optic alarm set in the manhole cover and receives the signal emitted by the signal transmitter.

Because the utility model safe, anti-theft inspection shaft and inspection shaft cover have adopted the above-mentioned technical scheme, promptly be provided with signal transmitter and acousto-optic alarm device along the mouth of inspection shaft, be provided with signal receiver and acousto-optic alarm device in inspection shaft cover, once If the inspection shaft cover is stolen from the inspection shaft, the signal emitted by the signal transmitter cannot be received by the signal receiver. At this time, the signal transmitter drives the sound and light alarm installed on the edge of the inspection shaft to issue an audible and visual alarm, prompting pedestrians and vehicles to detour. To avoid danger, at the same time, the signal receiver drives the sound and light alarm installed in the manhole cover to issue an audible and visual alarm to prevent the manhole cover from being stolen; in this way, the safety of the manhole to prevent the manhole cover from being stolen or missing is realized, and personal injury is avoided. and property safety are threatened.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Fig. 1 is the structural representation of the safe, anti-theft inspection shaft and inspection shaft cover of the utility model.

Detailed ways

As shown in Figure 1, the inspection shaft and the inspection shaft cover of the safety of the utility model, antitheft include inspection shaft 2 and cover the inspection shaft cover 1 on the inspection shaft, also comprise signal transmitter 8, signal receiver 7, two power supplies 3 and 4 and Two acousto-optic alarms 5 and 6, the two power supplies 3 and 4 and two acousto-optic alarms 5 and 6 are respectively located at the edge of the inspection shaft 2 and in the inspection shaft cover 1, the audible-visual alarms 5 and 6 Powered by the power sources 3 and 4, the signal transmitter 8 is located at the edge of the inspection shaft 2 and powered by the power supply 4 located at the edge of the inspection shaft 2, and the output connection of the signal transmitter 8 is located at the edge of the inspection shaft 2 The sound and light alarm device 6 at the mouth, the signal receiver 7 is located in the inspection shaft cover 1 and is powered by the power supply 3 located in the inspection shaft cover 1, and the output connection of the signal receiver 7 is located in the inspection shaft cover 1 The acousto-optic alarm 5 and receive the signal emitted by the signal transmitter 8.

The safe, anti-theft inspection shaft and inspection shaft cover of the utility model are provided with a signal transmitter 8 and an acousto-optic alarm 6 along the mouth of the inspection shaft 2, and a signal receiver 7 and an acousto-optic alarm 5 are arranged in the inspection shaft cover 1. Once the inspection shaft cover 1 is stolen from the inspection shaft 2, the signal emitted by the signal transmitter 8 cannot be received by the signal receiver 7. At this time, the signal transmitter 8 drives the sound and light alarm device 6 located at the edge of the inspection shaft 2 to send an audible and visual alarm, prompting Pedestrians and vehicles detour to avoid danger. At the same time, the signal receiver 7 drives the sound and light alarm device 5 located in the inspection shaft cover 1 to issue an audible and visual alarm to prevent the inspection shaft cover 1 from being stolen; The inspection well is safe when the cover is missing, and the personal and property safety are avoided from being threatened.
