Abstract

The invention relates to a moisture-proof and water-proof photoelectric sensor; a plurality of mounting bolts are in threaded connection with a mounting bottom plate; a fixed sleeve is arranged in an outer shell and connected with a supporting rod. A connecting plate is arranged on the supporting rod, and a photoelectric sensor body is mounted on the connecting plate; a light-transmitting part is arranged on the outer shell; a cooling fan is arranged on the side wall of the outer shell, and a connecting frame is arranged at an air outlet of the cooling fan; vent holes are formed in the connecting frame; an annular plate is arranged in the connecting frame, and a sealing ring is arranged on the annular plate; a sealing pressing plate is arranged in the connecting frame in a sliding mode, and a telescopic spring is arranged on the sealing pressing plate and connected with the connecting frame. A driving device is arranged in the outer shell and located above the connecting frame, and a pressing plate is connected to the driving device; a pressing bulge is arranged on the pressing plate. The photoelectric sensor is convenient and fast to assemble and disassemble, has good waterproof and moisture-proof effects on the photoelectric sensor, has a good heat dissipation effect, improves the use performance and prolongs the service life of the photoelectric sensor.

Description

technical field [0001] The invention relates to the technical field of photoelectric sensors, in particular to a moisture-proof and waterproof photoelectric sensor. Background technique [0002] A photoelectric sensor generally consists of two parts: a processing path and a processing element. Its basic principle is based on the photoelectric effect, which converts the measured changes into changes in optical signals, and then further converts non-electrical signals into electrical signals with the help of photoelectric elements. The photoelectric effect refers to irradiating an object with light, which can be regarded as a series of photons with a certain energy bombarding the object. At this time, the photon energy is transferred to the electron, and the entire energy of a photon is absorbed by one at a time. When the electrons are absorbed, the state of the electrons will change after they get the energy transmitted by the photons, so that the object irradiated by the li...
