Detailed Description
To facilitate understanding of those skilled in the art, the present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, a cable shaft water level alarm structure, including cable shaft 1, 1 upper cover of cable shaft is equipped with well lid 2, still include floater level sensor 4 and alarm 3, floater level sensor 4 sets up in cable shaft 1, floater level sensor 4 includes movable frame 43, mount 42, float 44 and proximity switch 46, movable frame 43 articulates on mount 42, movable frame 43 can be on mount 42 vertical rotation, float 44 sets up on movable frame 43, proximity switch 46 sets up on mount 42, proximity switch 46 electricity is connected on alarm 3, if movable frame 43 when rotating on mount 42, movable frame 43 can be close to or keep away from proximity switch 46.
The cable well 1 refers to a vertical passage leading from an underground passage to the ground, and the upper end of the cable well 1 is a well head.
The well lid 2 is used for covering and establishing on the well head of cable shaft 1. In the in-service use, when the user need overhaul the cable of underpass or change, lift well lid 2 on the well head of cable shaft 1, can overhaul or change the cable in the underpass through cable shaft 1.
The float 44 is less dense than water and the float 44 is intended to float on the surface of the water. In practical use, as the water level in the cable well 1 changes, the position of the float 44 in the cable well 1 changes, which drives the movable frame 43 to rotate on the fixed frame 42, for example, a warning water level is set in the cable well 1, the proximity switch 46 is set at the warning water level, as the water level in the cable well 1 rises, the position of the float 44 in the cable well 1 rises, which drives the movable frame 43 to approach the proximity switch 46, the proximity switch 46 triggers to generate a trigger signal, and the alarm 3 receives the trigger signal to issue an alarm, thereby timely reminding a user that the water level in the cable well 1 exceeds the warning water level.
The utility model discloses in, floater level sensor 4 can detect the water level in cable shaft 1 in real time, if the water level in cable shaft 1 exceeds when the take the altitude, then trigger proximity switch 46 and alarm 3 and initiate the police dispatch newspaper, in time remind the too high problem of water level in the user's cable shaft 1, moreover, proximity switch 46 is one kind and need not to contact the switch that can trigger with floater and adjustable shelf 43, can possess better water-proof effects, thereby be fit for using in filling cable shaft 1 of water, consequently this cable shaft water level alarm structure has the structure and retrencies, but real-time automatic detection and warning, the advantage of reliable operation.
The movable frame 43 includes a trigger portion, and a proximity switch 46 is disposed on a rotation path of the trigger portion, wherein the proximity switch 46 defines a rotation angle of the movable frame 43 on the fixed frame 42. In actual use, if the trigger part rotates to abut against the proximity switch 46, the proximity switch 46 is triggered to generate a trigger signal; if the trigger is rotated to disengage the proximity switch 46, the proximity switch 46 is not triggered by the trigger.
The trigger part is a magnetic member 45, and the proximity switch 46 is a reed switch. The magnetic reed switch is an electric switch triggered by the magnetic field of the magnetic member 45, and comprises a glass tube (not shown in the figure) and two magnetic reed pieces (not shown in the figure), wherein the two magnetic reed pieces are sealed in the glass tube, and can be contacted or separated under the action of the magnetic member 45. The proximity switch 46, which is a reed switch, further improves the waterproof effect. In the present embodiment, the magnetic member 45 is a magnet.
The movable frame 43 is hinged to the fixed frame 42 by a hinge 47, so that the movable frame 43 rotates on the fixed frame 42.
The integral structure of the movable frame 43 is a rod piece, the integral structure of the fixed frame 42 is a rod piece, the hinge 47 is arranged between two ends of the movable frame 43, the hinge 47 is also arranged at one end of the fixed frame 42, and the floater 44 and the magnetic piece 45 are respectively arranged at two ends of the movable frame 43.
The floating ball liquid level sensor 4 comprises a sliding block 41, a sliding rail 5 is fixedly arranged on the inner side wall of the cable well 1, the sliding block 41 is slidably arranged on the sliding rail 5, and the sliding block 41 can vertically slide on the sliding rail 5, so that the height position of the floating ball liquid level sensor 4 in the cable well 1 can be adjusted, and different warning water levels can be detected by the water level warning structure of the cable well 1.
The sliding block 41 can be in interference fit on the sliding rail 5, and a damping force is generated between the sliding block 41 and the sliding rail 5. In practical use, the user can push the slider 41 to slide on the sliding rail 5 against the damping force, and the slider 41 remains positioned on the sliding rail 5 without external force, thereby further facilitating the user to adjust the position of the slider 41 on the sliding rail 5.
The cable well water level alarm structure further comprises a lead 6, wherein the lead 6 is electrically connected between the proximity switch 46 and the alarm 3, so that communication between the proximity switch 46 and the alarm 3 is realized.
