Accompanying drawing explanation
Accompanying drawing 2 is the perspective structure figure of photoelectric level metering device.
Embodiment
Photoelectric level metering device of the present utility model, as shown in Fig. 1 to 2, comprises the casing 1 of hollow, and the interior transparent gauge line 2 that is vertically provided with of casing 1 is also provided with many group electrooptical devices 3 up and down in casing 1.
Every group of electrooptical device comprises optical sender structure 4 and the optical receiver 5 that can move up and down in casing 1, and the light of optical sender structure 4 transmittings is received by optical receiver 5 through gauge line 2.
On the opening that casing 1 upper and lower arranges, fixed block 6 is installed, fixed block 6 the inners are all provided with pickup groove 7, gauge line 2 two ends are arranged on respectively in the pickup groove 7 of corresponding fixed block 6, in fixed block 6, be all provided with fluid passage 8, fluid passage 8 is all communicated with gauge line 2, between gauge line 2 ends and corresponding pickup groove 7 bottom lands, O-ring seal 9 is all installed, heavy ball 10 is also housed in gauge line 2.
One of them fluid passage 8 is connected with a feed flow feed flow power pump by pipeline.
The optical sender structure 4 of every group of electrooptical device 3 and optical receiver 5 all comprise the regulating block 11 of hollow, regulating block 11 is all arranged on the chute 12 of casing 1 outer wall setting, the interior installation transmitting illuminant 13 of regulating block 11 of optical sender structure 4, the interior installation optical receiver 14 of regulating block 11 of optical receiver 5, optical receiver 14 is electrically connected to feed flow feed flow power pump, regulating block 11 is all provided with light hole 15, the light hole 15 of two regulating blocks 11 is relative, and regulating block 11 is attached on the tube wall of gauge line 2 with the one side of light hole 15.
