Abstract
The utility model relates to a photoelectric material level device, in particular to a high-protection photoelectric material level device. The photoelectric material level device comprises a height adjusting rod, a data collecting single chip microcomputer, a connection cable and a photoelectric position sensor; the photoelectric position sensor is connected with the data collecting single chip microcomputer by the connection cable; all the parts are mounted in a metal protective shield with a transparent probing window; the transparent probing window is formed by a glass sheet and sealing rubber rings; the photoelectric position sensor is spirally matched with the metal protective shield by external threads and realizes a watertight property by rotationally extruding the glass sheet and the sealing rubber rings. The high-protection photoelectric material level device is simple in structure and quite small in maintenance amount, has good dustproof, anti-corrosion, anti-seismic, shock-resistant and pressure resistant properties; as the photoelectric technology is adopted, no complex electric lines exist, and no mechanical transmission parts exist, so various malfunctions are further avoided, the material level control alarm of the instrument is very reliable without the need of debugging, and the photoelectric material level device is easy to maintain and is not influenced by environment and can continuously operate for a long time.
Description
Technical field
The utility model relates to a kind of photoelectricity level detector, is specifically related to a kind of high protection photoelectricity level detector.
Background technology
The detection of the controlling level in solid material (pellet, powder) storehouse; the normal height that adopts photoelectricity level detector to detect and control material level; when material level reaches the height of technological requirement; the photoelectricity level detector closing of contact or disconnection; send alerting signal; alert is noted, the interlocking action protection of the line correlation of going forward side by side.
If worked under perfect condition, the effect of photoelectricity level detector is good, and actual working environment is generally very severe, particularly graininess and granular material.In order to reduce the pollution of dust from flying to staff and environment, in each unloading and transfer point, all to carry out the spray sprinkler dirt that goes out, itself just has certain humidity and corrosivity some materials, working time is when slightly longer, each metal position of photoelectricity level detector will oxidation corrosion, the mud that dust forms can adhere to conducting surface, impact and intercept propagation and the reception of photosignal, thus cause the malfunctioning or misoperation of photoelectricity level detector.
Summary of the invention
For overcoming the deficiencies in the prior art part, the utility model provides a kind of high protection photoelectricity level detector, causes the technical matters of malfunctioning or misoperation to solve existing photoelectricity level detector adhesion dust and mud.
The technical scheme that the utility model technical solution problem adopts is: high protection photoelectricity level detector, this photoelectricity level detector comprises height regulating rod, data acquisition single-chip microcomputer, stube cable and photoelectrical position sensor, and this photoelectrical position sensor is connected with described data acquisition single-chip microcomputer by described stube cable; Above-mentioned parts are installed in a shelter-clad with transparent detecting window, described transparent detecting window is comprised of glass sheet and sealing rubber ring, described electric position sensor coordinates with described shelter-clad spiral by external thread, and realizes water-stop by glass sheet described in rotary squeezing and sealing rubber ring.
Shelter-clad, glass sheet, sealing rubber ring form photoelectricity level detector protective cover, whether photoelectrical position sensor has object to exist for front end, and sensing results is sent to data acquisition single-chip microcomputer by stube cable, by single-chip microcomputer, carry out corresponding analysis and judgement.
Further, described height regulating rod be two thickness differences, can be mutually nested metal circular tube, wherein the tube wall of thick pipe is provided with a lock screw, for locking or discharging, is enclosed within its inner mini diameter tube.By the length of the adjustable feeler arm of this structure, realize and change the function of surveying height of materials.
Further, the inner chamber of described thick pipe and mini diameter tube is used for arranging power lead and the signal wire of described photoelectrical position sensor, and plays protective action.
Beneficial effect: this product structure is simple, maintenance is very little, has good dustproof, anticorrosion, antidetonation, shock-resistant and withstand voltage properties.Owing to adopting photoelectric sense technology, without complicated electric wiring, without any mechanical transmission component, and then avoid the appearance of various misoperations, and the material level of this instrument is controlled report to the police very reliable, need not debug, for ease of maintenaince, not affected by environment, long-time running continuously.
Accompanying drawing explanation
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model,
Fig. 2 is three-dimensional view of the present utility model,
Fig. 3 is that height regulating rod discharges the view after mini diameter tube.
