In addition, the terms "first", "second" and the like are only used for differentiation in description and cannot be understood as indicating or implying relative importance.

[0031] In addition, the term "same" and the like do not mean that the components must be absolutely the same, but there can be slight differences. The term "vertical" only means that the positional relationship between the components is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0032] Please refer to Figures 1-4 The utility model provides a technical scheme: the auxiliary device of putting down of surveying and mapping unmanned ship, including base 1 and putting down board 2, base 1 and putting down board 2 one end articulate, the other end of putting down board 2 can be lifted up, still including linkage assembly and support assembly, support assembly is installed to the bottom surface of base 1, linkage assembly is located between support assembly and putting down board 2, when the end of putting down board 2 is lifted up, support assembly is driven to descend through linkage assembly.

[0033] In the present scheme, the end of base 1 away from the articulated end can be provided with a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is hinged to the end of putting down board 2 away from the articulated end. The hydraulic cylinder can be of model DG-80.

[0034] The top surface of the putting down board 2 is provided with a fence, and the end of the putting down board 2 hinged to the base 1 is provided with an open mouth for the unmanned ship to enter the water.

[0035] The bottom surface of the base 1 can be provided with a roller to facilitate the transportation of the unmanned ship. When the support assembly is not lowered, the bottom surface of the support assembly is higher than the bottom surface of the roller.

[0036] In use, the articulated end of the base 1 and the putting down board 2 is directed towards the water area, and the end of the putting down board 2 away from the water area is lifted up by starting the hydraulic cylinder, which causes the putting down board 2 to be in an inclined state. Under the influence of gravity, the unmanned ship on the putting down board 2 falls downward along the inner side of the inclined putting down board 2, thereby achieving the launching of the unmanned ship.

[0037] In the process of lifting the end of the launching plate by the hydraulic cylinder, the supporting assembly is driven to descend through the transmission of the linkage assembly, and as the launching plate is lifted, the supporting assembly gradually moves downward until it abuts against the ground, thereby generating friction between the supporting assembly and the ground to slow down the reaction force generated on the base 1 when the unmanned ship is launched, and to enhance the stability of the base 1.

[0038] When the auxiliary lowering device of the surveying and mapping unmanned ship is used, the launching plate 2 lowers the unmanned ship at the same time, the supporting assembly is driven to abut against the ground through the linkage assembly, so as to enhance the stability of the base 1, and prevent the base 1 from being moved due to the reaction force when the unmanned ship is launched, thereby preventing the surrounding personnel from being injured.

[0039] In the embodiment, the supporting assembly comprises a supporting plate 3 and a first inserting rod 4, the linkage assembly is connected with the supporting plate 3, the first inserting rod 4 is installed on the supporting plate 3, and the bottom surface of the first inserting rod 4 is lower than the bottom surface of the supporting plate 3.

[0040] In specific use, in the process of lifting the end of the launching plate by the hydraulic cylinder, the supporting plate 3 and the first inserting rod 4 are driven to move downward through the transmission of the linkage assembly until the supporting plate 3 abuts against the ground, and at the same time, since the ground near the water area is mostly composed of soil, the first inserting rod 4 is inserted into the soil when the supporting plate 3 abuts against the ground, and the first inserting rod 4 is vertically inserted into the soil to increase the resistance to the lateral movement of the base 1.

[0041] In the embodiment, a second inserting rod 401 is arranged on the outer side of the lower end of the first inserting rod 4, the second inserting rod 401 is perpendicular to the first inserting rod 4, and a plurality of second inserting rods 401 are vertically arranged.

[0042] In specific use, when the first inserting rod 4 is inserted into the soil, the second inserting rod 401 further improves the insertion stability of the first inserting rod 4 and the soil.

[0043] In the embodiment, the first inserting rod 4 is hollow, a vertical plate 402 is arranged in the first inserting rod 4, and the central part of the vertical plate 402 is rotationally connected with the inner wall of the first inserting rod 4.

[0044] A through hole is arranged on the side wall of the lower end of the first inserting rod 4, the through hole is used for the second inserting rod 401 to pass through, and one end of the first inserting rod 4 is connected with the vertical plate 402.

[0045] An extrusion cylinder 5 is slidably connected in the first inserting rod 4, the upper end of the extrusion cylinder 5 is connected with the bottom surface of the base 1, the lower end of the extrusion cylinder 5 is sleeved on the vertical plate 402, and the inner wall of the lower end of the extrusion cylinder 5 abuts against the outer wall of the vertical plate 402.

[0046] When the support plate 3 and the first inserting rod 4 are not moved downward, the inner wall of the extrusion cylinder 5 abuts against the middle part of the vertical plate 402, at this time, the vertical plate 402 is not easy to incline under the extrusion of the extrusion cylinder 5, and in this state, the second inserting rod 401 is located in the through hole of the first inserting rod 4;

[0047] In specific use, when the support plate 3 and the first inserting rod 4 are driven by the linkage assembly to move downward, the extrusion cylinder 5 is fixedly connected with the base 1, and when the first inserting rod 4 is driven to move downward, the position of the extrusion cylinder 5 does not change, the vertical plate 402 is driven to move downward with the first inserting rod 4, the position of the vertical plate 402 under the extrusion of the extrusion cylinder 5 gradually moves upward, and when the upper end of the vertical plate 402 is extruded, the lower end of the vertical plate 402 is driven to move toward the direction of the through hole, so that the second inserting rod 401 passes through the through hole and penetrates into the soil.

[0048] In the embodiment, the inner wall of the extrusion cylinder 5 is provided with an extrusion ring 501, the extrusion ring 501 is located between the extrusion cylinder 5 and the vertical plate 402, and the extrusion ring 501 is made of flexible material.

[0049] The hole diameter through which the vertical plate 402 passes is reduced by the extrusion ring 501 arranged in the extrusion cylinder 5.

[0050] In specific use, the extrusion ring 501 is used as the abutting part of the extrusion cylinder 5 and the vertical plate 402, and because the extrusion ring 501 is flexible, when the extrusion cylinder 5 and the vertical plate 402 are relatively moved, the extrusion ring 501 is compressed to enable the extrusion cylinder 5 and the vertical plate 402 to normally move.

[0051] In the embodiment, the linkage assembly comprises a first connecting rod 6, a sliding block 601 and a telescopic rod 602, a sliding groove for sliding the sliding block 601 is formed in the side wall of the base 1, the sliding groove extends along the length direction of the base 1, the two ends of the first connecting rod 6 are respectively hingedly connected with the sliding block 601 and the support plate 3, and the end of the support plate 3 away from the first connecting rod 6 is connected with the bottom surface of the base 1 through the telescopic rod 602.

[0052] In the natural state, the first connecting rod 6 is in an inclined state, and the end connected with the sliding block 601 is higher than the end connected with the support plate 3, at this time, the sliding block 601 is located at the end of the sliding groove away from the support plate 3.

[0053] In specific use, when the sliding block 601 slides toward the end of the sliding groove close to the support plate 3, the first connecting rod 6 gradually changes from the inclined state to the vertical state, because the first connecting rod 6 is made of rigid material, when the upper end of the first connecting rod 6 moves horizontally, the lower end moves downward, and then the support plate 3 and the first inserting rod 4 are synchronously driven to move downward.

[0054] In the embodiment, the linkage assembly further comprises a second connecting rod 603, both ends of the second connecting rod 603 are hingedly connected with the sliding block 601 and the lower plate 2 respectively.

[0055] In the embodiment, the first connecting rod 6 is in an inclined state in a natural state, and the second connecting rod 603 is also in an inclined state, and the end of the second connecting rod 603 connected with the lower plate 2 is higher than the end connected with the sliding block 601.

[0056] In specific use, when the lower plate 2 is lifted, since one end of the second connecting rod 603 is connected with the lifted end of the lower plate 2, the second connecting rod 603 is gradually changed from the inclined state to the vertical state due to the lifting of the lower plate 2, and during the change, since the lower end of the second connecting rod 603 is connected with the sliding block 601, the sliding block 601 is driven to slide towards the end of the support plate 3 close to the sliding groove.

[0057] In the embodiment, the bottom surface of the lower plate 2 is provided with a protrusion 7 protruding downward, the top surface of the base 1 is provided with a groove for inserting the protrusion 7, and the groove is provided with an elastic supporting piece abutting against the protrusion 7.

[0058] In specific use, when the unmanned ship is transported, the cooperation of the elastic supporting piece and the protrusion 7 can effectively increase the shock resistance of the lower plate 2, thereby protecting the unmanned ship in the lower plate 2 from being collided with the fence on the lower plate 2 due to shaking.

[0059] In the embodiment, the elastic supporting piece comprises a force receiving piece and two springs 8, the force receiving piece is in sliding cooperation with the groove, the top surface of the force receiving piece is pressed to move away from each other, the two springs 8 are respectively located on the two sides of the force receiving piece, and the two ends of the spring 8 are respectively abutted against the force receiving piece and the groove.

[0060] In the embodiment, since the unmanned ship is placed on the lower plate 2, the gravity of the lower plate 2 is pressed on the force receiving piece through the protrusion 7, so that the two sides of the force receiving piece move away from each other, and since the two sides of the force receiving piece are connected with the springs 8, the springs 8 can relieve part of the pressure received by the force receiving piece.

[0061] In the embodiment, the force receiving piece comprises a force receiving plate 9, two hinged plates and two sliding plates 901, the groove is provided with a guide rod 10 extending along the length direction of the base 1, the two sliding plates 901 are respectively located at the two ends of the guide rod 10 and are in sliding cooperation with the guide rod 10, and one end of the hinged plate is hingedly connected with the sliding plate 901, and the other end is hingedly connected with the end of the force receiving plate 9.

[0062] In specific use, when the force receiving plate 9 is pressed downward by the protrusion 7, the two hinged plates drive the two sliding plates 901 to move away from each other, so that the two sliding plates 901 press the springs 8, and the elasticity of the springs 8 relieves part of the pressure received by the two sliding plates 901.
