Embodiment approach

[0043] As an embodiment, the driving device includes a DC motor 33, a speed reducer 20, and a power supply 32 for supplying power to the DC motor; the DC motor 33 is connected to the speed reducer 20 through a flexible coupling; the speed reducer 20 The output shaft is coaxially connected with one end of the drum 22;

[0044] Further, the accelerator 20 adopts a worm gear reducer, and the worm gear reducer has a self-locking function, which can ensure that when the inspection robot system suddenly loses power and the DC motor of the telescopic rod cannot provide power, the telescopic rod will not stop. Slide down under its own gravity.

[0045] Further, the power supply 32 is a lithium battery, and the mounting frame 21 is provided with a charging terminal seat connected to the lithium battery to charge the lithium battery.

[0046] Further, the other end of the drum 22 is also provided with a second encoder 27, the second encoder 27 is coaxially connected with the drum 22, a...

Abstract

The invention discloses a multi-degree-of-freedom modular inspection robot. The multi-degree-of-freedom modular inspection robot comprises a track trolley suitable for straight and curved rails, a telescopic device and a detection device, wherein the track trolley adopts the structure that transmission chains are arranged on a track; the track trolley realizes horizontal movement through cooperation between chain wheels and the chains to convey an overall inspection robot to be in front of a to-be-detected switch board room cabinet, thus achieving accurate positioning; the telescopic device isfixed at the lower end of the track trolley to realize up-and-down vertical stable and reliable movement and to guarantee the movement synchronism; the detection device is fixed at the lower end of the double-track telescopic device; and a sensor, a partial discharge sensor probe, a high-definition camera, an infrared thermal imager, a two-axis holder, an electric push rod and the like are arranged inside the detection device to realize real-time detection of the switch board room cabinet. The movement stability and reliability and accurate positioning of the multi-degree-of-freedom modular inspection robot in a triaxial direction are realized.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a multi-degree-of-freedom modular inspection robot. Background technique [0002] With the continuous increase of the number of electricity users in our country, the user's requirements for the quality of electricity consumption continue to increase, and it is very important to ensure the normal and safe operation of power distribution equipment, so that the inspection of power distribution rooms has received greater attention. In addition, with the improvement of the automation level of the power system and the popularity of unattended power distribution rooms, the safety of equipment operation is subject to more stringent tests. At present, most power distribution rooms in China still adopt the traditional manual inspection method. Due to the constraints of many factors of the inspectors, missed inspections and false inspections occur from time to time, whic...
