Description

Technical Field

[0001] The utility model belongs to the technical field of underwater measuring devices, and in particular relates to a suspended fixing device for a multi-beam depth sounder. Background Art

[0002] Multibeam echo sounder is a sounding equipment used in marine surveying and mapping in the early days. With the improvement of multibeam echo sounding technology, more and more underwater topography measurements of inland rivers also need to use multibeam to collect data, especially underwater topography measurements of reservoirs. In actual work, since most reservoirs are located in river valleys and valleys, there are relatively few places for ships to launch. Since the reservoirs are long, they generally need to be operated in sections, with daily measurements and return measurements. The echo sounder probe is placed in the water, the measurement ship has a large resistance, and the operation takes a lot of time.

[0003] In multi-beam underwater survey operations, inland rivers mostly use rubber boats to fix depth sounders. They can fix the multi-beam transducer well and keep the transducer vertically fixed. Driving at low speeds can improve measurement accuracy. However, the transducer is always underwater on the way to the work area, which increases the ship's resistance and takes a long time to travel to and from the work area. Installing the transducer in the air can save time on traveling to and from the work area. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer and more understandable, the technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] Reference Figures 1 to 3The utility model discloses a multi-beam echo sounder suspended fixing device, comprising a side frame 9, a crossbar assembly and a panel 10. There are two side frames 9 and they are arranged opposite to each other. The crossbar assembly comprises a first crossbar 1, a second crossbar 2 and a third crossbar 11. The first crossbar 1, the second crossbar 2 and the third crossbar 11 are all connected between the two side frames 9. The first crossbar 1 and the second crossbar 2 are in the same vertical plane, the third crossbar 11 and the second crossbar 2 are in the same horizontal plane, the panel 10 is embedded between the second crossbar 2 and the third crossbar 11, and a multi-beam echo sounder mounting structure is provided on any side frame 9.

[0019] The side frame 9 and the crossbar assembly can form a frame body set on the rubber boat to facilitate the placement of the multi-beam echo sounder. The third crossbar 11, the second crossbar 2 and the panel 10 are combined to act as a support plate, and the fiber optic compass, SIM box, RTK conversion box and other equipment of the multi-beam echo sounder system can be placed on the panel 10.

[0020] The multi-beam echo sounder installation structure includes a first steel plate 5, a second steel plate 13 and a rotation adjustment connection assembly. The first steel plate 5 and the second steel plate 13 are both fixedly mounted on the side frame 9. The first steel plate 5 is in a vertical state and the second steel plate 13 is in a horizontal state. The rotation adjustment connection assembly is mounted on the first steel plate 5. A first bolt hole 6 is provided on the first steel plate 5 below the rotation adjustment connection assembly. The first bolt hole 6 can be fixedly connected to the multi-beam probe 21 by bolts. Second bolt holes 3 are provided on both sides of the rotation adjustment connection assembly on the second steel plate 13. The second bolt holes 3 can be fixedly connected to the multi-beam probe 21 by bolts. The rotation adjustment connection assembly includes a mounting nut 15, a bearing 4 and a steel sheet 16. The bearing 4 is mounted on the first steel plate 5. The steel sheet 16 is fixedly mounted on the first steel plate 5 to prevent the bearing 4 from slipping. The nut 15 is mounted on the inner ring of the bearing 4. The nut 15 can be fixedly connected to the multi-beam probe 21 by bolts.

[0021] like Figure 4 As shown, the multi-beam probe rod 21 is provided with two mounting screw holes 22 , which can be connected to the first bolt hole 6 , the second bolt hole 3 or the nut 15 by bolts.

[0022] Therefore, in summary, the working method of the multi-beam echo sounder suspended fixture is as follows:

[0023] Step 1, select a suitable place at the work site, then connect and fix the side frame 9, the first cross bar 1, the second cross bar 2 and the third cross bar 11 with screws. After the connection is completed, place the panel 10 in the horizontal plane formed by the second cross bar 2 and the third cross bar 11 and fix it.

[0024] Step 2, take out the multi-beam probe 21 and the multi-beam transducer of the multi-beam echo sounder, connect the multi-beam transducer and the bottom of the multi-beam probe 21, install the RTK receiver to the top of the multi-beam probe 21, connect the multi-beam transducer to the probe through the multi-beam connection port 23, and go deep into the water.

[0025] Step 3, lift and place the assembled multi-beam echo sounder suspended fixture in the middle of the rubber boat, and fix it to the rubber boat with a lanyard, hook or cable. After the multi-beam echo sounder fixture and the rubber boat are fixed together, place the multi-beam probe 21 on the first steel plate 5 of the gunwale 9, and connect and fix it with the nut 15 and the first bolt hole 6 on the first steel plate 5 by passing the bolt through the mounting screw hole 22 on the multi-beam probe 21.

[0026] Step 4, determine the working distance. If the distance to the underwater location to be measured is short, just follow the above steps to connect. If the distance to the underwater location to be measured is far, the multi-beam probe 21 can be placed on the first steel plate 5 of the port frame 9 first, and installed by passing bolts through the mounting screw holes 22 on the multi-beam probe 21 and the nuts 15 on the first steel plate 5. Then, the multi-beam probe 21 is rotated to the second steel plate 13 of the port frame 9 through the bearing 4, and connected and fixed with the first bolt hole 3 on the second steel plate 13 through the bolts. After reaching the working position area, the bolts on the first bolt hole 3 are removed, and the probe is rotated to a vertical position through the bearing 4 and connected and fixed with the second bolt hole 6 on the first steel plate 5.

[0027] Step 5. After the installation of the suspended device is completed, rotate the narrow transducer probe of the sounding rod vertically to the water surface, set up the RTK base station, and make the RTK receiver on the multi-beam sounding rod 21 complete the communication connection with the base station receiver. Place the fiber optic compass, SIM box, RTK conversion box and other equipment of the multi-beam sounding system on the panel 10, connect them to the multi-beam sounding monitor in turn, and connect the battery to power on. After all the equipment of the multi-beam sounding system is debugged and connected, check whether the system components are operating normally, whether the communication lines are connected correctly, and check whether the equipment is installed and fixed firmly. After confirming that the debugging is normal, start the sounding operation.
