Correspondingly, a prompt sign can be set on the outer surface of the cover-type cover body 5 to indicate the position of the signal transmission area 15, so that the signal transmission assembly 4 can be attached to the area when the lock is unlocked.
When the hidden box body is used, the hidden box body is arranged below the ground, and the upper end surface of the cover type cover body 5 is displayed on the ground without any opening position; the lower part of the embedded box 6 is connected with a corresponding power supply pipeline to supply power to the controller 13, and other needed equipment can be arranged at the same time, so that the structure of the embedded box 6 is optimized to supply power, and one feasible option is given here: the lower part or the bottom of the side wall of the embedded box body 6 is provided with a connecting pipe orifice 12, and the connecting pipe orifice 12 is provided with a power supply cable which is connected with a controller 13. When the scheme is adopted, other needed equipment is arranged in the embedded box body 6, such as an irrigation valve body, a power distribution switch, a control valve and the like, and is connected with a main pipeline and the like embedded underground through the connecting pipe orifice 12.
The above is an embodiment exemplified in this example, but this example is not limited to the above-described alternative embodiments, and a person skilled in the art may obtain various other embodiments by any combination of the above-described embodiments, and any person may obtain various other embodiments in the light of this example. The above detailed description should not be construed as limiting the scope of the present embodiments, which is defined in the claims and the description may be used to interpret the claims.
