Description

Technical Field

[0001] This utility model relates to the field of hydrological lead fish, specifically a hydrological lead fish device with ADCP. Background Technology

[0002] The hydrological lead weight is a lead weight used for hydrological cableway surveying. Manufactured according to national standards, it is a hydrological surveying instrument made of metallic lead or a lead-iron mixture, possessing a certain weight and a slender ratio with a streamlined shape. The lead weight's structure is primarily based on a streamlined body, with a suspension mechanism and current meter suspension rod mounted on its back. Together with the longitudinal and transverse tails and signal source, it forms the complete lead weight unit.

[0003] In addition to maintaining basic functions, the new lead fish has added devices such as ADCP, radio wave current meter and horizontal sampler, which better enable the use of cableway to complete various hydrological test tasks across the entire river section and meet the requirements of the development of water test equipment in the new era. However, existing lead fish devices that install ADCP often fix the ADCP inside the lead fish with bolts or other structures. This installation method is not convenient for disassembling and assembling ADCP, and it is time-consuming and labor-intensive when ADCP needs to be replaced or repaired.

[0004] Therefore, a hydrological lead fish device with ADCP is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, a hydrological lead fish device with ADCP includes a lead fish body 1; the lead fish body 1 has an internal mounting groove 12, and an ADCP body 13 is slidably connected to the inner side of the mounting groove 12; the lead fish body 1 has an internal groove 14, and a screw 15 is rotatably connected to the inside of the groove 14; a moving block 16 is threadedly connected to the surface of the screw 15; a positioning plate 17 is fixedly connected to the side of the moving block 16; the positioning plate 17 is slidably connected to the mounting groove 12, and a friction pad is provided on the inner side of the positioning plate 17; a worm gear 18 is fixedly connected to the surface of the screw 15; a worm 19 is rotatably connected to the inside of the mounting groove 12, and the worm 19 meshes with the worm gear 18; a rotating rod 110 is fixedly connected to the side of the worm 19, and the rotating rod 110 is rotatably connected to the lead fish body 1; during operation, the ADCP body 13 is inserted into the inside of the mounting groove 12, and the rotating rod 110 is rotated to allow passage. The rotating rod 110 drives the worm gear 19 to rotate, which in turn drives the worm wheel 18 to rotate. The worm wheel 18 then drives the screw 15 to rotate, which in turn drives the moving block 16 to slide inside the groove 14. The moving block 16 then drives the positioning plate 17 to move, so that its inner side fits against the ADCP body 13. The positioning plates 17 on both sides clamp and position the sides of the ADCP body 13. Reversing the rotating rod 110 allows the screw 15 to move the positioning plate 17 outward, separating the positioning plate 17 from the ADCP body 13. At this point, the ADCP body 13 can be pulled out of the mounting groove 12 for disassembly and assembly. This step, by setting up the rotating rod 110, worm gear 19, and worm wheel 18, can drive the positioning plates 17 on both sides to move, clamping and positioning the ADCP body 13 inside the mounting groove 12, while also facilitating the disassembly and assembly of the ADCP body 13.

[0024] like Figure 1 and Figure 3 As shown, a first mounting bracket 21 is slidably connected to the surface of the lead fish body 1, and a second mounting bracket 22 is slidably connected to the surface of the lead fish body 1. The second mounting bracket 22 is slidably connected to the first mounting bracket 21. A fixed plate 23 is fixedly connected to the side of the second mounting bracket 22. A movable plate 24 is slidably connected inside the fixed plate 23. A float plate 25 is fixedly connected to the top of the movable plate 24. A first bolt 26 is threadedly connected inside the float plate 25. During operation, the float plate 25 can be connected to a fixed object through the first bolt 26 inside the float plate 25. This step connects the float plate 25 to the fixed object through the first bolt 26 inside the float plate 25. The float plate 25 plays a balancing role for the lead fish body 1, increasing the balance of the lead fish body 1 in the water.

[0025] like Figure 3As shown, a connecting block 31 is fixedly connected to the side of the first mounting bracket 21. A second bolt 32 is threadedly connected to the inside of the connecting block 31. The second bolt 32 is threadedly connected to the fixing plate 23. During operation, rotating the second bolt 32 separates it from the fixing plate 23, thus separating the first mounting bracket 21 from the second mounting bracket 22. This step, by setting the second bolt 32 and the connecting block 31, allows for the disassembly and assembly of the first mounting bracket 21 and the second mounting bracket 22. At the same time, it allows for the adjustment of the positions of the first mounting bracket 21 and the second mounting bracket 22 on the surface of the lead fish body 1, increasing the range within which the floating plate 25 provides a balancing effect on the lead fish body 1.

[0026] like Figure 3 As shown, the fixed plate 23 has a positioning bolt 41 internally threadedly connected, and the movable plate 24 has a positioning hole 42 internally. The positioning bolt 41 is threadedly connected to the positioning hole 42. During operation, there are several positioning holes 42. By rotating the positioning bolt 41, it can be connected to the corresponding positioning hole 42. This step can fix the height of the floating plate 25 when the positioning bolt 41 is connected to the corresponding positioning hole 42, so as to prevent the movable plate 24 from continuously moving up and down inside the fixed plate 23 when the lead fish body 1 is on the water surface, causing the floating plate 25 to shake.

[0027] like Figure 2 and Figure 4 As shown, a first waterproof pad 51 is provided on the side of the positioning plate 17. The surface of the first waterproof pad 51 is in contact with the mounting groove 12. A second waterproof pad 52 is fixedly connected to the inner side of the mounting groove 12. The inner side of the second waterproof pad 52 is in contact with the worm gear 19. During operation, when the positioning plate 17 moves, it drives the first waterproof pad 51 to move. This step can increase the sealing of the positioning plate 17 and the edge of the groove 14 through the first waterproof pad 51, and can increase the sealing of the connection between the worm gear 19 and the mounting groove 12 through the second waterproof pad 52, preventing water from entering the inside of the groove 14.

[0028] like Figure 3 and Figure 5 As shown, a support rod 61 is fixedly connected to the bottom of the first mounting frame 21, and a flow guide is provided on the side of the support rod 61. During operation, the first mounting frame 21 moves while driving the support rod 61 to move. In this step, when the lead fish body 1 is placed on the ground, the support rod 61 can support the first mounting frame 21 to prevent the bottom surface of the ADCP body 13 from contacting the ground and causing wear to the ADCP body 13. By setting the flow guide, the resistance of the support rod 61 in the water can be reduced.

[0029] Working principle: By inserting the ADCP body 13 into the mounting slot 12, rotating the rotating rod 110 drives the worm gear 19 to rotate, which in turn drives the worm wheel 18 to rotate. The worm wheel 18 then drives the screw 15 to rotate, which in turn drives the moving block 16 to slide inside the groove 14. The moving block 16 then moves the positioning plate 17, causing its inner side to fit against the ADCP body 13. The positioning plates 17 on both sides clamp and position the sides of the ADCP body 13. Reversing the rotating rod 110 allows the screw 15 to... The positioning plate 17 moves outward to separate the positioning plate 17 from the ADCP body 13. At this time, the ADCP body 13 can be pulled out of the mounting slot 12 for disassembly and assembly. The floating plate 25 can be connected to the fixed object by the first bolt 26 inside the floating plate 25. The second bolt 32 is rotated to separate it from the fixed plate 23, and the first mounting bracket 21 and the second mounting bracket 22 can be separated. Then, the positions of the first mounting bracket 21 and the second mounting bracket 22 on the surface of the lead fish body 1 are adjusted. The first mounting bracket 21 moves while driving the support rod 61 to move.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
