Abstract

The invention discloses an anti-explosion image pickup instrument, which comprises a base, a rotating tube body, an image pickup instrument and an image pickup instrument rotating device, wherein the image pickup instrument is connected with the rotating tube body through the image pickup instrument rotating device, the anti-explosion image pickup instrument also comprises a tube body rotating device, the tube body rotating device comprises a transmission base plate, a motor installing frame, a motor, a driving gear, a driven gear, a spring, a spring press ring, a transmission shaft, a first bearing, a second bearing and a bearing press ring, the anti-explosion image pickup instrument also comprises a closed loop servo control device, the closed loop servo control device comprises a detecting mechanism and a servo control mechanism, and the detecting mechanism comprises an optical grating installing shaft, an optical grating disc, a signal receiver and an optical grating installing element. The anti-explosion image pickup instrument has the advantages that when the motor is overloaded, a transmission gear can automatically slip, so that the normal operation of equipment is protected, the transmission line connection is safe and reliable, the service life of the equipment is prolonged, the control precision is high, and in addition, the effect is good.

Description

technical field [0001] The invention relates to an explosion-proof camera. Background technique [0002] Explosion-proof cameras are mainly used in toxic environments and severely polluted environments. They are used to monitor the surrounding cameras. Usually, explosion-proof cameras need to be driven by a motor to rotate. As a motor used to output rotational torque, it is most likely to be overloaded due to equipment resistance. As a result, the motor is damaged, and at the same time, the transmission gear and the transmission shaft are subjected to excessive torque to cause overload friction and damage. Therefore, in order to increase the service life of the equipment, it is necessary to prevent the equipment from being overloaded when the torque is output. Protect the normal operation of the equipment for a long time. [0003] The current one is the electrical connection between different explosion-proof chambers. According to the national standard GB3836-2010, each cab...
