DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a telescopic depth sounding device for a waterway patrol boat, comprising a patrol boat hull 1, a protective cover 4, an I-shaped wheel 7 and a counterweight cover 18. A fixing plate 2 is fixed to the upper left side of the front end of the deck of the patrol boat hull 1, a servo motor 3 and a protective cover 4 are installed on the upper end of the fixing plate 2, a bearing seat is installed at the left end inside the protective cover 4, and a rotating shaft 6 is horizontally installed in the inner ring of the bearing seat, an I-shaped wheel 7 is fixedly sleeved on the annular side of the rotating shaft 6, and a measuring wire 8 is wound around the annular side of the I-shaped wheel 7, and mounting plates 9 are installed on the lower sides of the left and right ends of the inner side of the protective cover 4, and two mounting plates 9 Electric push rods 10 are installed at the relative inner ends, and arc-shaped pieces 11 are installed at the movable ends of the two electric push rods 10. Sponge wiping pieces 12 are arranged on the inner sides of the two arc-shaped pieces 11. An adjusting groove 13 is opened at the lower end of the protective cover 4. Multiple springs 14 are horizontally installed on the left and right ends of the adjusting groove 13. Rubber pieces 15 are installed at the relative inner ends of the multiple springs 14. Elastic sponge blocks 16 are arranged on the inner sides of the two rubber pieces 15. A depth sounder probe 20 is installed inside the counterweight cover 18. This design solves the problem that the original device has a limited extension degree and is inconvenient to use for depth sounding in deeper waters.

[0019] As the first embodiment of the utility model: the motor shaft 5 is installed at the left end of the servo motor 3, and the motor shaft 5 passes through the protective cover 4 and is connected to the rotating shaft 6 through the coupling. When the added motor shaft 5 is driven to rotate, the rotating shaft 6 and the I-shaped wheel 7 can be driven to rotate through the coupling. A transparent sealing plate 19 is horizontally arranged at the lower end of the counterweight cover 18. The added transparent sealing plate 19 can prevent water leakage from the lower end of the counterweight cover 18. The upper end of the counterweight cover 18 is penetrated by a mounting tube 17, and the protruding end of the measuring wire 8 passes through the adjustment slot 13, the fixing plate 2, the mounting tube 17 and is connected to the depth sounder probe 20. The center of gravity of the added mounting tube 17 and the counterweight cover 18 is downward, so that when the depth sounder probe 20 is driven to move downward, it will not easily swing.

[0020] The two elastic sponge blocks 16 are both attached to one side of the drooping end of the measuring wire 8, and the measuring wire 8 can be wiped by the two added elastic sponge blocks 16. The two sponge wiping pieces 12 are respectively located on the left and right sides of the drooping end of the measuring wire 8, and the two added sponge wiping pieces 12 can be driven by the two electric push rods 10 to move toward each other to wipe the measuring wire 8.

[0021] As the second embodiment of the utility model: in actual use, the servo motor 3 is started, and the servo motor 3 drives the motor shaft 5 to rotate clockwise, and the motor shaft 5 drives the rotating shaft 6 to rotate through the coupling, so that the I-shaped wheel 7 is also driven to perform the line laying operation. During this process, the measuring wire 8 will slowly extend downward due to the weight of the installation tube 17 and the counterweight cover 18, and then it can drive the depth sounder probe 20 to move down to the water area for depth measurement. After the measurement is completed, the servo motor 3 is controlled to drive the motor shaft 5 to rotate counterclockwise, so that the measuring wire 8 can be rewound to the annular side of the I-shaped wheel 7. At this time, the two electric push rods 10 are started, and the movable ends of the two electric push rods 10 will drive the two arc pieces 11 and the two sponge wiping pieces 12 to move toward each other until the two sponge wiping pieces 12 are attached to the left and right ends of the measuring wire 8. During the retraction process of the measuring wire 8, its surface will be wiped by the two elastic sponge blocks 16 and the two sponge wiping pieces 12, so as to ensure the cleanliness of the surface of the measuring wire 8.
