Problems solved by technology

The laying of non-frozen model ice is uneven, and the non-freezing model ice of the same size is too concentrated, which is far from the control of model ice in the test requirements, which often leads to a large deviation in the resistance value obtained by the crushed ice test

Embodiment 1

[0024] The non-frozen model ice uniform laying device used in the drag pool of the present invention consists of four parts: a model ice conveying device, a trailer, a lateral moving device, and a uniform stirring device. The model ice conveying device is mainly composed of four parts: universal wheels, base, scissor lifting device and ice storage device. The lateral movement is mainly composed of a linear module, a servo motor and a controller. By inserting the slider on the linear module into the groove 18 on the outer wall of the uniform stirring device, it can drive the uniform stirring release device to move. The uniform stirring release device is a cylindrical device with a main shaft passing through the middle. The upper end of the main shaft is two motors that can drive it to rotate and move up and down. The lower end of the main shaft is a driven shaft that moves and rotates with the main shaft. The evenly stirred release is filled with different sizes of non-frozen m...

Embodiment 2

[0032]The present invention is an inventive device that can evenly stir the non-freezing model ice and lay it on the water surface of the test water area. In front of the trailer, place the mobile device horizontally along the direction of the trailer. The mobile device consists of a linear module fixed on the trailer that is equal to the width of the trailer, and a servo motor placed at the end of the linear module. The output shaft of the servo motor is connected to the linear module. The screw connection of the module and the controller connected to the servo motor can realize the position control of the uniform stirring release device placed on the lateral moving device. The uniform stirring release device fixed on the lateral moving device is a cylindrical device, and the whole device is fixed on the moving device through a fixing device. The device can achieve uniform stirring and release of non-frozen model ice, which is mainly composed of the outer wall of the cylindri...

Abstract

The utility model relates to a device for laying non-freezing model ice evenly inside a towing pool, which belongs to the field of ship operation. The structure of the present invention includes a horizontal moving device, a vertical moving device, a uniform stirring release device, and a non-freezing model ice delivery device. The uniform stirring release device is fixed on the slider of the horizontal moving device, and the horizontal moving device is installed on the trailer of the longitudinal moving device The upper part of the main shaft in the axial direction of the uniform stirring release device is connected with the rotating motor and the axial motor respectively, and a plurality of driven rods are fixed at the lower part of the main shaft. The upper part of the outer wall of the uniform stirring release device is a fixed part, and the lower part of the outer wall is a moving part. The upper part of the outer wall is hinged, and the ice pour port of the non-freezing model ice delivery device cooperates with the ice inlet port of the uniform stirring release device. The invention fully and evenly mixes different model ices; through the control of the trailer and the lateral moving device, the release device can reach any position of the pool, saving manpower and improving efficiency; the invention is convenient for dismantling.

Description

technical field [0001] The invention belongs to the field of ship operation, and in particular relates to a device for evenly laying non-freezing model ice inside a towing pool. Background technique [0002] With the melting of the Arctic and Antarctic ice regions, the development of Arctic waterways has attracted more and more attention from the international community. As a service ship that breaks ice, opens up channels, and guides ships to navigate in ice areas, icebreakers play an important role in the normal passage of routes in polar regions. Therefore, the optimization and design of the icebreaker is very important. The ice breaking resistance experiment of the icebreaker is one of the most important means to study the interaction force of ship ice. For ice breaking ice resistance tests of icebreakers, most of the non-freezing model ice is used at this stage. Due to the large number of non-freezing model ice required in the test, and the limitation of production co...
