Specific implementation manner

[0028] As Figure 1-2 shown, an acoustic wave detection device for channel measurement that is convenient for replacing the detector includes a monitoring platform main body 1. A detection mechanism 2 is installed on the top of the monitoring platform main body 1. Connecting plates 5 are fixedly connected to the four corners of the surface of the monitoring platform main body 1. Floating balls 6 are fixedly connected to both sides of each connecting plate 5. A bottom shell 11 is fixedly connected to the bottom of the monitoring platform main body 1. The bottom shell 11 is threadedly connected to a support rod 9. A counterweight 10 is fixedly connected to the bottom of the support rod 9.

[0029] As Figure 1 、 Figure 4 shown, the detection mechanism 2 includes a base 14. The base 14 is fixedly installed on the top of the monitoring platform main body 1. A plurality of grooves 15 are circumferentially formed on the surface of the base 14. The size of each groove 15 matches the size of the insertion block 16. The insertion block 16 can be inserted into the corresponding groove 15. The positions and quantities of the insertion block 16 and the groove 15 correspond one by one. An acoustic wave detector 17 is installed on the side of the insertion block 16 opposite to the groove 15.

[0030] As Figures 4-7As shown, a fixed cylinder 18 is fixedly connected to the top of the base 14. The front and rear sides of the side wall of the fixed cylinder 18 are open, and a through hole is opened in the top plate of the fixed cylinder 18. A movable plate 19 is slidably arranged on the side wall of the fixed cylinder 18. Arc-shaped through holes are opened on the left and right of the movable plate 19, and the arc-shaped through holes match the side wall of the fixed cylinder 18. The movable plate 19 passes through the side wall of the fixed cylinder 18 through the arc-shaped through holes, so that the movable plate 19 can move freely up and down relative to the fixed cylinder 18. A first connecting rod 21.1 is fixedly arranged at the central position on the movable plate 19. The first connecting rod 21.1 freely passes through the through hole in the top plate of the fixed cylinder 18. Second connecting rods 21.2 are fixedly arranged on the left and right sides of the outer edge of the movable plate 19. The heights of the first connecting rod 21.1 and the second connecting rods 21.2 are greater than the height of the fixed cylinder 18. The first connecting rod and the second connecting rods are connected to the horizontal plate and form a pulling plate 21. A spring 20 is arranged in the fixed cylinder 18. The lower end of the spring 20 is connected to the movable plate 19, and the upper end abuts against the inner top surface of the fixed cylinder 18. The spring 20 is in a compressed state under normal conditions and presses the movable plate 19 tightly against the base 14.

[0031] As Figure 4 shown, a plurality of connecting blocks 22 are fixedly connected to the surface of the movable plate 19. A fixed insertion plate 23 is fixedly connected to the bottom of each connecting block 22. A slot is arranged on the corresponding insertion block 16. After the fixed insertion plate 23 extends vertically downward, it can extend into the slot of the insertion block 16, so that the outward removal of the insertion block 16 can be restricted.

[0032] As Figures 6-7 shown, by arranging the fixed cylinder 18, the movable plate 19 can be guided and limited, so as to increase the stability of the movable plate 19 during movement.

[0033] During use, when the pulling plate 21 is pulled upward, the movable plate 19 moves upward, drives the fixed insertion plate 23 to move upward through the connecting block 22, and the fixed insertion plate 23 is removed from the insertion block 16, so as to release the limit on the plurality of acoustic wave detectors 17 and realize unlocking. At this time, the spring 20 is further compressed. When the pulling plate 21 is released, the movable plate 19 is reset again by the elastic force of the spring 20. At this time, the fixed insertion plate 23 is inserted into the insertion block 16 to limit and fix the acoustic wave detector 17 and realize locking.

[0034] Preferably, as Figures 2-3 shown, a reinforcing rod 12 is fixedly installed on the surface of the support rod 9 through bolts. The top of the reinforcing rod 12 is fixedly connected to the bottom case 11 through bolts, and the number of the reinforcing rods 12 is three. By arranging the reinforcing rod 12, the stability between the bottom case 11 and the support rod 9 can be increased to prevent the support rod 9 from shaking during use.

[0035] Preferably, as Figure 3 shown, a battery pack 13 is fixedly installed in the inner cavity of the bottom case 11, and the battery pack 13 supplies power to the device.

[0036] Preferably, as Figure 1 shown, a protective rod 7 is installed through the top of the connecting plate 5, and a floating cylinder 8 is fixedly sleeved on the surface of the protective rod 7. By providing the floating cylinder 8, the buoyancy of the device can be increased, and at the same time, the protection on the surface of the protective rod 7 can also be enhanced. By providing the protective rod 7, the protective rod 7 can also protect the bottom of the device to prevent the bottom of the device from being collided.

[0037] Preferably, as Figure 1-2 shown, the number of floating balls 6 is eight, and reinforcing plates are fixedly connected to both sides of the connecting plate 5, and the rear sides of the reinforcing plates are fixedly connected to the monitoring platform main body 1. The connecting plate 5 drives the floating balls 6 to protect the periphery of the device, and at the same time, the floating force of the device can also be increased; by providing the reinforcing plates, the stability of the connection between the connecting plate 5 and the monitoring platform main body 1 can be increased.

[0038] Preferably, as Figure 1-2 shown, a bracket 3 is fixedly connected to the top of the monitoring platform main body 1, and a radio signal transmitter 4 is fixedly connected to the top of the bracket 3. The radio signal transmitter 4 in this device can remotely transmit the measurement data to the control platform so that the staff can remotely observe the measurement data of the device.

[0039] Working principle and process:

[0040] 1). When in use, first, install the support rod 9 on the bottom case 11 so that the counterweight 10 can increase the weight of the bottom of the device.

[0041] 2). Then, place the device on the waterway so that the monitoring platform main body 1 can measure the waterway through the acoustic wave detector 17.

[0042] During the measurement, the connecting plate 5 will increase the overall buoyancy of the monitoring platform main body 1 through the floating balls 6 to prevent the device from being overturned by the waves during detection. At the same time, the connecting plate 5 will also protect the outside of the device through the protective rod 7 to avoid collisions between the device and external objects, so that the device can be effectively protected during use.

[0043] 3). When the acoustic wave detector 17 needs to be replaced or maintained, the user pulls the movable plate 19 by pulling the pulling plate 21. When the movable plate 19 moves upward, it will drive the fixed insertion plate 23 to move upward through the connecting block 22 until the fixed insertion plate 23 is removed from the insertion block 16, thereby releasing the limit on the insertion block 16.

[0044] 4), Subsequently, the user pulls the acoustic wave detector 17 outwards until the insertion block 16 is removed from the groove 15, so that the user can replace the acoustic wave detector 17. When multiple acoustic wave detectors 17 need to be replaced at the same time, after the fixed insertion plate 23 is removed from the insertion block 16, the user can quickly remove multiple acoustic wave detectors 17 from the device.
