The invention discloses a contact detection type water spraying mechanism. The contact detection type water spraying mechanism comprises a box body, a detection box, a partition plate, an
electromagnet, a first guide rod, an armature, a first spring, a clamping head, a rotating pin, a swing rod, a second guide rod, an arc-shaped contact head, second springs, water spraying mechanism bodies and a proximity switch. When a vehicle performs water replenishment operations, the arc-shaped contact head and a landscape guardrail are in contact to be stressed to push the second guide rod to slide along the swing rod, and when a detection block triggers the proximity switch, the
electromagnet the armature are attracted to drive the clamping head fixedly connected with the first guide rod to move upwards to be separated from the swing rod, the swing rod rotates along the rotating pin, and at the moment, water is pumped into the water spraying mechanism. Water lines sprayed by a plurality of spray heads form an annular three-dimensional
coating structure, and therefore, water supplementing operations are performed on green plants under the condition that the
water consumption is reduced. The mechanism is simple in structure, through
contact type detection and positioning, the landscape guardrail can be rapidly positioned, manual positioning is not needed, connection is improved, besides, annular three-dimensional water spraying is adopted, and consumption of
water resources is reduced.
