Problems solved by technology

However, it is not very flexible in actual use, and the rudder change requires the robot to navigate a large corner to complete the steering action, and it cannot achieve heavy-duty operations due to the limited driving capacity during deep-sea operations; some special functions When an underwater robot is working, such as an underwater robot used for arming, the loud noise generated by the rotation of the propeller will also expose the position of the robot and reduce the concealment performance

Embodiment 1

[0030] Such as Figure 1-5Shown, a kind of water-jet propulsion type underwater spherical heavy-duty robot comprises spherical shell 1, and spherical shell 1 comprises upper hemispherical shell 1-1 and lower hemispherical shell 1-2, and the lower periphery of upper hemispherical shell 1-1 An upper boss is provided, and a lower boss is arranged on the upper periphery of the lower hemispherical shell 1-2. The upper boss and the lower boss are correspondingly evenly distributed with longitudinal bolt holes, and a circle of diameters of 7 to 9 mm is provided on the inner side of the upper boss. The upper sealing groove and the inner side of the lower boss have a lower sealing groove with a diameter of 7-9mm. The upper hemispherical shell 1-1 and the lower hemispherical shell 1-2 are locked and fixed by eight bolts matching the corresponding number of longitudinal bolt holes, and through Sealing rings are installed in the upper and lower sealing grooves to seal the connection to pr...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that the underwater spherical heavy-duty robot is also equipped with an intelligent control manipulator. Extend the grabbing cabin through the intelligent opening and closing window for deep-sea grabbing operations, and set up a storage bin in the grabbing cabin, and the submarine target objects grabbed by the intelligent control manipulator can be stored in the storage bin for later scientific research Wait.

Abstract

The invention discloses a water jet propulsion type underwater spherical heavy-load robot. A spherical shell is divided into an upper power cabin and a lower working cabin through a middle horizontalsealing baffle. A water jet propulsion system is mounted in the upper power cabin; the system comprises a motor, a high-pressure water pump and nozzles which are arranged on the horizontal sealing baffle, the nozzles are uniformly distributed at four corners of the edge part of the horizontal sealing baffle and the nozzles hermetically extend out of the spherical shell; the motor drives and controls the high-pressure water pump to suck external seawater and spray the external seawater through the nozzles, the course and navigational speed of the underwater spherical heavy-load robot are adjustable by controlling the nozzles in different directions to spray water for propulsion, an observation cabin and a ballast water cabin are arranged in the lower working cabin, and the observation cabinis used for observing the seabed environment and transmitting the seabed environment to an offshore console through radio. The volumetric hydraulic pump is adopted to drive medium-high pressure waterjet propulsion, so that the bearing capacity of the underwater robot in operation is greatly improved, and the maneuvering characteristics of the underwater robot are improved through vectorized propulsion of the nozzle.

Description

technical field [0001] The invention belongs to the technical field of underwater vehicles, and in particular relates to a water-jet propelled underwater spherical heavy-duty robot. Background technique [0002] The earth is rich in seawater resources, and the seabed resources are even more numerous. In order to vigorously develop marine resources, countries all over the world have devoted a lot of energy to the research of deep-sea underwater robots. The propeller of the traditional underwater robot is propelled by the propeller, and the main propulsion is generated by the rotation of the blade to make the robot move forward. When changing the attitude, the rudder around the underwater robot swings to achieve the purpose of turning. However, it is not very flexible in actual use, and the rudder change requires the robot to navigate a large corner to complete the steering action, and it cannot achieve heavy-duty operations due to the limited driving capacity during deep-sea...
