Problems solved by technology
Existing photoelectric sensors can basically meet the measurement requirements, but in some cases, such as in harsh natural conditions, in violent storms, or need to measure the changes of objects, but the existing photoelectric sensors are not sensitive to the working environment The requirements are high, and it is basically impossible to measure the required data under harsh conditions
If the volume of the object to be measured is large, there may be a phenomenon that the signal change of the object cannot be detected
Moreover, the role of the photoelectric sensor is relatively simple

The invention discloses a photoelectric sensor, which comprises an outer housing provided with an accommodating space, a rotating mechanism arranged inside the accommodating space, a plurality of transmitters movably arranged inside the accommodating space, a receiver arranged inside the accommodating space, a detection circuit arranged inside the accommodating space, and a temperature sensor arranged inside the accommodating space. One end of the accommodating space of the outer housing is provided with a hemispherically-shaped light-transmissive side plate. The radial length of the accommodating space of the outer housing gradually reduced from one end to the other end thereof. The sidewall of the accommodating space of the outer housing is provided with an opening. The rotating mechanism is composed of a supporting stage, pivoting parts and a first power mechanism used for driving the pivoting parts to rotate. The transmitters, positioned at one end of the outer housing, are used for transmitting the light to a to-be-measured object and are pivoted to the pivoting parts. The receiver is used for receiving the reflected light. The detection circuit, positioned at the other end of the outer housing, is connected with the receiver. The temperature sensor telescopically extends out of the accommodating space or telescopically retracts into the accommodating space via the opening. The pivoting parts are in one-to-one correspondence with the transmitters. The plurality of pivoting parts are symmetrically disposed on the supporting stage along the axial direction of the outer housing and are distributed in the shape of a circular arc.
Description
technical field [0001] The invention relates to a photoelectric sensor. Background technique [0002] A photoelectric sensor is a sensor that uses a photoelectric element as a detection element. It first converts the measured changes into changes in optical signals, and then further converts the optical signals into electrical signals with the help of photoelectric elements. A photoelectric sensor generally consists of three parts: a light source, an optical path, and a photoelectric element. Existing photoelectric sensors can basically meet the measurement requirements, but in some cases, such as in harsh natural conditions, in violent storms, or need to measure the changes of objects, but the existing photoelectric sensors are not sensitive to the working environment The requirements are high, and it is basically impossible to measure the required data under harsh conditions. If the volume of the object to be measured is large, there may be a phenomenon that the signal ...
