Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the underwater high-irradiation-resistant manipulator structure provided by the present invention, compared with a general multi-joint manipulator, the joints of the manipulator adopt an irradiation-resistant design, which removes unnecessary sensors and replaces the sensors that must be retained with Radiation-resistant type, and rationalize the position of electronic components, so that the radiation-resistant requirements of the manipulator body can be met. At the same time, the joints of the robotic arm are designed to be waterproof, and a single joint can be sealed with only three sealing rings.

[0021] Compared with the general multi-joint manipulator, the present invention adopts the radiation-resistant design for the joints of the manipulator, removes unnecessary sensors, replaces the sensors that must be retained wit...

Abstract

The invention discloses an underwater high-irradiation-resistant mechanical arm joint structure which comprises a plurality of joint assemblies and a mechanical arm and further comprises a base assembly, the joint assemblies are connected with one another, the joint assemblies are connected with the base assembly, and the joint assemblies are connected with the mechanical arm. The joint sealing device has the beneficial effects that each joint is provided with three sealing rings, and a good sealing effect can be achieved. The whole mechanical arm can be communicated, and sealing gas is introduced into the mechanical arm, so that the mechanical arm has good sealing performance. According to the mechanical arm, electronic components sensitive to irradiation are not arranged, the electronic components are uniformly placed in the base assembly and are physically shielded, and therefore the whole mechanical arm can resist large irradiation.

Description

technical field [0001] The invention belongs to an underwater operation device of each container of a primary circuit of a nuclear power plant, in particular to an underwater high-irradiation-resistant mechanical arm joint structure. Background technique [0002] With the vigorous promotion and application of my country's nuclear power generation, military nuclear power plants, and irradiation industries. There will be more and more nuclear facilities requiring regular inspection or maintenance. [0003] At present, the inspection or maintenance of nuclear facilities is mostly carried out through special equipment and tools. In this way, different equipments are often used, so the operation and maintenance cost of the nuclear power plant will be very large. [0004] The multi-joint robotic arm has been widely used in the field of industrial automation due to its multiple degrees of freedom and high flexibility, and can replace manual work to complete various complex tasks....
