DETAILED DESCRIPTION

[0019] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 9 , the present invention provides a technical solution: Embodiment 1, a side-operating mechanical arm for an ocean-going vessel, comprises: a mounting base 1.

[0021] Specifically, an adjusting arm 2, an adjusting small arm 3 and a connecting seat 4 are sequentially installed on the mounting seat 1, and the connecting seat 4, the adjusting small arm 3 and the adjusting arm 2 are sequentially connected end to end, and the adjusting arm 2 is rotatably installed on the front of the mounting seat 1 through a hinge support, and the connecting seat 4, the adjusting small arm 3 and the adjusting arm 2 can all be rotated separately to change the position of the connecting seat 4, and the rotation of the connecting seat 4, the adjusting small arm 3 and the adjusting arm 2 are all powered by a driving device known in the prior art such as an oil cylinder or an air cylinder, and the mounting seat 1 is slidably installed on the outer surface of the side of the ship through a track, and the mounting seat 1 can be adjusted in position along the length direction of the track, thereby changing the connecting seat 4, a rotating table 5 is rotatably installed at one end of the connecting seat 4, and the rotating table 5 can be driven to rotate by the motor and gear known in the prior art, which will not be described in detail here. A mechanical claw assembly 6 is arranged at one end of the rotating table 5, and the mechanical claw assembly 6 is directly facing the sideboard drainage pipe 7 on the side of the ship. Through the mutual cooperation and adjustment of the mounting seat 1, the adjusting arm 2, the adjusting arm 3 and the connecting seat 4, the mechanical claw assembly 6 can be aligned with the sideboard drainage pipe 7. After the front end of the mechanical claw assembly 6 is inserted into the inner cavity of the sideboard drainage pipe 7, the mechanical claw assembly 6 is driven to rotate by rotating the rotating table 5, and the mechanical claw assembly 6 can clear the blockage in the inner cavity of the sideboard drainage pipe 7; Secondly, the mechanical claw assembly 6 includes a fixed bracket 61 fixedly mounted on the rotating table 5, and the fixed bracket 61 can rotate with the rotation of the rotating table 5. An adjusting bracket 62 is rotatably mounted on one end of the fixed bracket 61. The angle between the adjusting bracket 62 and the fixed bracket 61 can be adjusted, so as to control the opening angle of the front end of the mechanical claw assembly 6 to adapt to the inner cavity size of the side drain pipe 7. A clamping claw 63 is fixedly connected to one end of the adjusting bracket 62. The clamping claw 63 is arc-shaped, and a strip plate 631 is fixed on the inner wall. After the clamping claw 63 is inserted into the inner cavity of the side drain pipe 7, the adjusting bracket 62 is opened to adjust the clamping claw 63. The arc surface fits with the inner wall of the side drain pipe 7. At this time, the clamping jaw 63 rotates around the axis of the rotating table 5 to clean the impurities adhering to the inner wall of the side drain pipe 7. One end of the clamping jaw 63 is provided with a beveled edge 632, and a sawtooth groove 633 is provided on the beveled edge 632. The front end of the clamping jaw 63 is a "V"-shaped angle structure, which can be easily inserted into the blockage in the inner cavity of the side drain pipe 7. During the rotation of the clamping jaw 63, the sawtooth groove 633 can saw the blockage to more easily clean the blockage, avoiding the influence of the hardness of some blockages on the normal dredging and cleaning work; In addition, a reflector 52 is installed inside the rotating platform 5. The reflector 52 is in a triangular pyramid shape and is coated with a reflective coating 521 on the surface. When light is irradiated on the reflective coating 521, it can be reflected. A light guide 53 is fixedly installed on the side wall of the rotating platform 5. A reflector 531 is fixed in the inner cavity of the light guide 53. One end of the light guide 53 faces the side drain pipe 7, and the other end of the light guide 53 faces the reflector 52. The interior of the connecting seat 4 is hollow and a camera 41 is fixedly installed. The camera 41 faces the reflector 52. Figure 4 and Figure 5 As shown, the light from the outer side of one end of the light guide tube 53 enters the inner cavity of the light guide tube 53, is reflected by the reflector 531, and can be emitted from the other end of the light guide tube 53. At this time, the light just shines on the reflective coating 521 on the surface of the reflector 52, and the reflective coating 521 reflects the light for a second time, thereby shining the light on the camera 41. Therefore, although the camera 41 is located in the middle of the inner cavity of the connecting seat 4, it can monitor the image at the front edge of the rotating table 5, that is, the image of the position of the circle where the clamping claw 63 is located. The advantage of such a design is that when the bracket 62 is rotated and the opening size of the clamping claw 63 is adjusted, the camera 41 is used to monitor from the opening at one end of the light guide tube 53, so that it can be clearly observed whether the clamping claw 63 is in contact with the inner wall of the side drain pipe 7.

[0022] In order to avoid the reflector 52 and the other end of the light guide 53 from being misaligned with each other, the present application also has an installation cavity 51 in communication with the inner cavity of the connecting seat 4, and a fixed base 54 is fixed in the middle of the inner cavity of the installation cavity 51. The reflector 52 is fixed to one side of the reflector 52, and the fixed base 54 itself is in the shape of a truncated cone. The other end of the light guide 53 fits the surface of the fixed base 54 and is fixed thereto. The reflector 52 is relatively fixed to the rotating table 5 by being fixedly connected to the fixed base 54, and then relatively fixed to the light guide 53, so as to avoid the other end opening of the light guide 53 and the reflective coating 521 from being misaligned with each other. In addition, since the camera 41 itself remains relatively fixed to the connecting seat 4 and will not rotate, but the reflector 52 will rotate synchronously with the rotating table 5, the image area actually monitored by the camera 41 will also change with the rotation and movement of the light guide 53. The image area actually monitored by the camera 41 is in the shape of a circular ring and directly opposite to the side drain pipe 7.

[0023] In order to describe the structure of the light duct 53 in detail, the light duct 53 of the present application is arranged in a "<" shape, and the reflector 531 is fixedly installed at the corner of the inner cavity of the light duct 53. The camera 41 monitors the front of the light duct 53 by reflecting the light through the reflector 52 and the reflector 531. Three light ducts 53 are arranged and distributed in a circular array around the rotating table 5. The two ends of the light duct 53 face different directions. With the help of the reflector 531, the light in the inner cavity of the light duct 53 can be transported in a "<" shape. With the secondary reflection of the light by the reflective coating 521, it can ensure that the camera 41 can simultaneously monitor the images of multiple areas around the rotating table 5.

[0024] In order to drive the adjustment bracket 62 to rotate, the present application also has a telescopic member 55 fixed at the other end of the fixed base 54, the telescopic member 55 itself can be telescoped, and the inner cavity of the installation cavity 51 can be pre-installed with a battery and a controller known in the prior art to control the working telescope of the telescopic member 55. The telescopic member 55 adopts wireless control and is not connected to an external socket with a power cord, which can prevent the power cord of the telescopic member 55 from being twisted off when the rotating table 5 rotates. The movable end of the telescopic member 55 passes through the inner wall of one end of the rotating table 5 and extends to the outside of one end of the rotating table 5. The movable end of the telescopic member 55 is provided with a driving connecting rod 56 for driving the adjustment bracket 62 to rotate. When the telescopic member 55 is working and telescopic, the driving connecting rod 56 can be linked to drive the adjustment bracket 62 to rotate around one end of the fixed bracket 61, thereby changing the position of the clamp 63.

[0025] In order to connect the driving link 56 with the adjusting bracket 62, the present application also has a through groove 621 running through the middle of the adjusting bracket 62, one end of the driving link 56 extends to the inner cavity of the through groove 621 and maintains a rotational connection with the adjusting bracket 62 through a fixing pin 622, and an avoidance chamfer 623 is provided at the edge of one end of the through groove 621, so that the adjusting bracket 62 and the driving link 56 can only rotate relative to each other and will not separate from each other. The setting of the avoidance chamfer 623 can be used to increase the relative expansion angle between the driving link 56 and the adjusting bracket 62, thereby avoiding collision between the driving link 56 and the adjusting bracket 62 and affecting the rotational expansion of the adjusting bracket 62.

[0026] In order to drive the driving link 56 to move, the present application also has a connecting platform 551 fixed at the movable end of the telescopic member 55, and the other end of the driving link 56 is rotatably connected to the connecting platform 551 through a hinge support. The fixed bracket 61, the adjustment bracket 62 and the driving link 56 are each provided with three and distributed in a circular array. The three light guides 53 and the three fixed brackets 61 are spaced apart from each other, such as Figure 7 As shown, when the telescopic member 55 is extended or retracted, the connecting platform 551 is driven to move accordingly, and then the three adjustment brackets 62 can be synchronously rotated, unfolded, or gathered together through the synchronous linkage of the three driving connecting rods 56. It should be noted that the present application sets three fixed brackets 61, adjustment brackets 62 and driving connecting rods 56, which is only a number designed for easy understanding. In actual use, the number can be set to two, three, four... or more, which will not be elaborated here.

[0027] In order to prevent water and impurities from entering the inner cavity of the light guide 53, the present application also has a positioning slot 57 opened on the side wall of the rotating table 5, and the other end of the fixing bracket 61 is inserted into the inner cavity of the positioning slot 57 and is fixedly connected to the rotating table 5 by a countersunk bolt 58. Figure 6As shown in the figure, at least two countersunk bolts 58 are arranged at the end of each fixing bracket 61 as a group, which are used to ensure the connection strength and connection stability between the fixing bracket 61 and the rotating table 5. The fixing bracket 61 is an outward arc structure, and a connecting ring 611 is fixed in the middle of the fixing bracket 61. The connecting ring 611 fixes and connects the three fixing brackets 61 together, which can further improve the stability of the relative position between the three fixing brackets 61. One side of the connecting ring 611 is in contact with the open end of the light guide 53, and the connecting ring 611 fixes the light guide 53. After one end of the opening is blocked, water, dust, impurities, etc. can be prevented from entering the inner cavity of the light duct 53. A transparent window 612 corresponding to the light duct 53 is provided on the connecting ring 611. The transparent window 612 is a transparent structure, which ensures that the camera 41 can monitor the picture from one end of the light duct 53. When water or impurities adhere to the surface of the transparent window 612 and the connecting ring 611, the rotating table 5 rotates to drive the fixed bracket 61 and the connecting ring 611 to rotate, and the water and impurities can be thrown away from the surface of the connecting ring 611 and the transparent window 612 through centrifugal force.

[0028] In order to discharge the obstruction in the inner cavity of the side drain pipe 7 in time, the strip plate 631 of the present application is in a spiral structure, and the central angle of the strip plate 631 is smaller than the central angle of the clamping claw 63, such as Figure 8 As shown, the strip plate 631 acts as a structure of a conveying fan blade. When the clamp 63 rotates, the strip plate 631 can squeeze the obstruction inside the clamp 63, thereby discharging the obstruction in the inner cavity of the side drain pipe 7 to the outside of the port of the side drain pipe 7. In combination with the above, it can be seen that when the obstruction is discharged from the inner cavity of the side drain pipe 7, it is possible to adhere to the surface of the connecting ring 611 and the transparent window 612. However, since the rotating table 5 is in a rotating state at this time, even if the obstruction adheres to the surface of the transparent window 612, it will be thrown away in time, and the open end of the light guide 53 will not be blocked by the obstruction to affect the monitoring image of the camera 41. The height of one end of the strip plate 631 is smaller than the height of the other end. Fig. 9 As shown, the strip plate 631 will produce a certain cutting effect on the obstruction when squeezing and conveying the obstruction in the inner cavity of the side drain pipe 7, so as to avoid a large collision impact force on the device when the large obstruction is discharged. In addition, the side of the clamping jaw 63 with a smaller length is provided with an oblique chamfer 634, combined with Figure 8 As shown, the chamfer 634 is mainly used to reduce the resistance generated between the side of the clamping jaw 63 and the obstruction when the clamping jaw 63 rotates.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
