Embodiment 1

[0024] see Figure 1~2 , in an embodiment of the present invention, a photoelectric sensor multi-functional protection device, including a mounting case 1 and a protective cover, a protective glass 4 is embedded on the side wall of the mounting case 1, and a protective glass 4 is embedded on the side wall of the mounting case 1. Sponge strips are attached to the contact positions of the protective glass 4, which can buffer and protect the protective glass 4. The protective cover is arranged on the outside of the installation shell 1, and a gap is provided between the inner wall of the protective cover and the outer wall of the installation shell 1 to protect the protective glass 4. The side of the cover close to the protective glass 4 has an opening. Furthermore, a protective mechanism for protecting the protective glass 4 is installed on the protective cover. The protective mechanism includes a protective plate 6 and a switch for driving the protective plate 6 to open and clos...

Embodiment 2

[0028] see image 3 The difference between the embodiment of the present invention and embodiment 1 is that the outer wall of the installation housing 1 is located at the ventilation net 5 and is provided with a placement screen frame 23, and a desiccant is placed in the placement screen frame 23 for reducing Moisture enters the installation housing 1 .

[0029] The working principle of the present invention is: when the photoelectric sensor is working, the protection plate 6 is opened; Ventilation nets 5 are installed on both side walls of the housing 1. After the photoelectric sensor is placed on the placement board, the placement board descends downward under the action of gravity, and the placement board presses down on the horizontal section of the L-shaped bar 2, and the L-shaped bar 2 Rotate through the guide rod 3 to drive the splint 19 to move towards the photoelectric sensor, thereby realizing automatic positioning and clamping of the photoelectric sensor. The opera...

Abstract

The invention discloses a multifunctional protection device for a photoelectric sensor. The device comprises a mounting shell and a protective cover. Protective glass is mounted on one side wall of the mounting shell in an embedded manner; a temperature control unit is also mounted in the mounting shell and comprises a first spraying plate, a second spraying plate, a fan, a heating pipe, a temperature sensor, a motor, a turntable and a movable rod; the protective cover is also provided with a protective mechanism for protecting the protective glass; the protection mechanism comprises a protection plate and a switch mechanism for driving the protection plate to be opened or closed; an installation mechanism for installing a photoelectric sensor is arranged in the mounting shell and comprises an installation plate and a positioning mechanism. According to the invention, the temperature control unit is arranged and thus the photoelectric sensor can be fully operated, so that the work efficiency is improved; with the protective mechanism, when the photoelectric sensor does not work, the protection plate is rotationally located on the front side of the protective glass, and the protective glass can be protected; and with the installation mechanism, operation is easy, great convenience and high practicability are realized, and the photoelectric sensor can be easily disassembled or assembled.

Description

technical field [0001] The invention relates to the field of photoelectric technology, in particular to a multifunctional protection device for a photoelectric sensor. Background technique [0002] A photoelectric sensor is a device that converts light signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to that when light is irradiated on certain substances, the electrons of the substance absorb the energy of photons and a corresponding electric effect occurs. According to the different phenomena of photoelectric effect, photoelectric effect can be divided into three categories: external photoelectric effect, internal photoelectric effect and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells. The performance and characteristic curves of optoelectronic devices are analyzed. [0003] Since the photoelectr...
