Abstract
The utility model discloses a hard light interference-prevention liquid level detector, comprising a shell, a photoelectric liquid level sensor and a light transmission window; the photoelectric liquid level sensor is arranged in the shell; the light transmission window is arranged at the bottom of the shell to transmit the light emitted or received by the photoelectric liquid level sensor; a mounting seat is arranged at the bottom of the shell; multiple liquid leaking slots are formed in the edge part of the mounting part; a detection cavity is arranged in the middle of the mounting seat; the light transmission window is positioned in the detection cavity part. The hard light interference-prevention liquid level detector is characterized in that multiple anti-light interference stop walls arranged at the bottom, at the part of the detection cavity, of the shell; the anti-light interference stop walls and the liquid leaking slots are in one-to-one correspondence; a liquid inlet is formed between adjacent anti-light interference stop walls; the liquid leaking slots, the liquid inlets and the detection cavity are communicated. The phenomenon that the detection is influenced by hard light is avoided and the reliability on detection of the liquid level is improved.
Description
Technical field
The utility model relates to a kind of anti glare anti static coatings and disturbs liquid level detection device.
Background technology
At present, to water, oil and have in the level gauging of the liquid such as corrosivity, and in the detection of smokescope in gas etc., the general method that uses range estimation, this method had both been wasted manpower, precision is not again very high, some special occasions is (as the environment of toxic liquid and gas, the concentration of airtight nontransparent liquid in containers and smog etc.) very inconvenient again by the method for manual read's number, and some measured liquids and gases has corrosivity and inflammable and explosive feature, liquid level gauge and liquids and gases Long Term Contact, be corroded and cause measuring error, cause reducing greatly its serviceable life even and lost efficacy, although some sensor is powerful, because complex structure, expensive and people are hung back, now develop a kind of liquid level detection device, it is simple in structure, but in use find, when having high light, high light can go through test chamber by saturating liquid bath, thereby affect the measurement of liquid level, make level gauging unreliable.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, provides a kind of anti glare anti static coatings to disturb liquid level detection device, the phenomenon that it can avoid intense laser interfere impact to detect, thus improve the reliability that liquid level detects.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of anti glare anti static coatings disturbs liquid level detection device, comprise housing, the saturating window of photoelectric level transducer and light, photoelectric level transducer is arranged in housing, the saturating window of described light is arranged on the bottom of housing to see through the light that photoelectric level transducer sends or accepts, the bottom of housing is also provided with mount pad, the edge part of mount pad has multiple liquid baths, the middle part of mount pad is provided with test chamber, the saturating window of described light is positioned at test chamber position, it is characterized in that: the bottom of described housing is provided with multiple interference retaining walls against sunshine on the position of test chamber, and interference retaining wall against sunshine and described saturating liquid bath corresponding matching one by one, between adjacent interference retaining wall against sunshine, be provided with inlet, described saturating liquid bath, inlet and test chamber are connected.
Further see through in order to block better from saturating liquid bath the light of coming, the bottom of described mount pad is mutually concordant with the bottom of interference retaining wall against sunshine.
Further see through in order to block better from saturating liquid bath the light of coming, the transverse width of described saturating liquid bath is not more than the transverse width of interference retaining wall against sunshine.
Further, described saturating liquid bath has three, and described interference retaining wall corresponding against sunshine also has three.
Adopt after technique scheme, each liquid bath of the present utility model has an interference retaining wall against sunshine to be arranged on the exit of liquid bath, but leaving space flows by liquid, guarantee on the one hand flow direction test chamber, thereby detection liquid level, prevent again that on the other hand light from injecting test chamber by saturating liquid bath, the phenomenon that can avoid intense laser interfere impact to detect, thus improve the reliability that liquid level detects.
