[0027] See also Figure 1-4 ,The utility model provides a technical solution:
[0028] A water flow velocity detection device comprises a mounting plate 1 and a main unit 2, wherein the main unit 2 is fixedly mounted on the upper side of the mounting plate 1, and a connecting line 3 is arranged on the outer side of the main unit 2, and a sensor 4 is fixedly arranged on the outer end of the connecting line 3, an electric push rod 5 is arranged on the outer side of the mounting plate 1, one end of the electric push rod 5 is connected to the mounting plate 1, and a U-shaped block 6 is arranged on the other end of the electric push rod 5, a wire roller 7 for docking with the connecting line 3 is rotatably arranged on the inner side of the U-shaped block 6, a winding shaft 8 is fixedly arranged on the outer side of the main unit 2, and a positioning block 9 is fixedly arranged on the outer end of the winding shaft 8, a mounting groove 10 is opened on the upper side of the positioning block 9, and a positioning mechanism for docking with the connecting line 3 is arranged on the inner side of the mounting groove 10, and the winding roller 8 can conveniently reel up the connecting line 3 to avoid the disorder of the connecting line 3, thereby improving the overall convenience of use of the device.
[0029] Specifically, the positioning mechanism includes a fixed cylinder 11 fixedly arranged on both sides of the installation groove 10, and movable rods 12 are movably inserted into the inner sides of the two groups of fixed cylinders 11. The movable rods 12 movably penetrate the fixed cylinder 11 and extend to the outside, and the outer end of the movable rod 12 is located at the outer part of the fixed cylinder 11 and a clamping block 13 is fixedly arranged, and a spring 14 is arranged on the inner side of the fixed cylinder 11, one end of the spring 14 is connected to the inner side of the fixed cylinder 11, and the other end of the spring 14 is connected to the movable rod 12. The spring 14 does not deform in its initial state. When the two groups of clamping blocks 13 are pried apart and the connecting line 3 is passed through between the two groups of clamping blocks 13, the spring 14 is deformed. After the clamping block 13 is released, the elastic potential energy of the spring 14 is released to drive the clamping block 13 to clamp the connecting line 3, thereby ensuring the stability of the connecting line 3 and the sensor 4.
[0030] Furthermore, a mounting tube 15 is fixedly provided on the lower side of the mounting plate 1, and a connecting rod 16 is movably inserted into the inner side of the mounting tube 15. The connecting rod 16 movably passes through the mounting tube 15 and extends to the outside, and a fixing cone 17 is fixedly provided on the outer end of the connecting rod 16 at the outer part of the mounting tube 15. By providing the fixing cone 17, the entire device can be conveniently fixed to ensure the stability of the device when in use.
[0031] It is worth mentioning that a limit block 20 is fixedly arranged on the inner side of the mounting tube 15, and a limit groove 19 for docking with the limit block 20 is opened on the outer side of the connecting rod 16. When the connecting rod 16 is moved, the limit block 20 can be driven to slide in the limit groove 19, thereby improving the movement stability of the connecting rod 16.
[0032] It is worth noting that the outer side of the connecting rod 16 is respectively provided with a smooth surface 21 and a threaded surface 22 from top to bottom, and a turntable 18 for docking with the threaded surface 22 is rotatably provided on the outer side of the mounting tube 15. The connecting rod 16 is movably inserted into the mounting tube 15, which is convenient for supporting and fixing the mounting plate 1 while also facilitating the disassembly and carrying of the device.
[0033] In addition, multiple groups of anti-sliding blocks are fixedly provided on the outer side of the turntable 18, and the multiple groups of anti-sliding blocks are all made of soft materials. The anti-sliding blocks can increase the friction of the turntable 18, making the rotation of the turntable 18 more convenient.
[0034] It has to be said that a connecting disk 23 is fixedly provided on the inner side of the turntable 18, and an internal thread for docking with the threaded surface 22 is provided on the inner side of the connecting disk 23. When installing the connecting rod 16, the connecting rod 16 is first inserted into the inner side of the mounting tube 15, so that the limit block 20 moves along the limit groove 19. At this time, the smooth surface 21 on the outer side of the connecting rod 16 first enters the inner side of the mounting tube 15. When the threaded surface 22 on the outer side of the connecting rod 16 enters the inner side of the mounting tube 15, the turntable 18 is rotated at this time, so that the connecting disk 23 on the inner side of the turntable 18 is threadedly connected with the threaded surface 22, so that the connecting rod 16 can be conveniently fixed. At the same time, with the continuous rotation of the turntable 18, the limit block 20 and the limit groove 19 are limited, so that the connecting rod 16 cannot rotate, and can only move parallel to the inner side of the mounting tube 15, so that the height of the mounting plate 1 can be adjusted.
[0035] Working principle: first, place the device at a suitable position on the dam, fix the device as a whole by fixing the cone 17, then remove the connecting wire 3 from the winding shaft 8, then pass the connecting wire 3 through the two groups of blocks 13, support the connecting wire 3 by the wire roller 7, so that the sensor 4 is vertically downward, then turn on the electric push rod 5 by an external power supply, the electric push rod 5 extends to drive the U-shaped block 6 and the wire roller 7 to move, and the movement of the wire roller 7 drives the connecting wire 3 and the sensor 4 to move. At this time, the two groups of blocks 13 need to be broken apart to both sides to ensure the normal movement of the connecting wire 3 until the U-shaped block 6 moves to a suitable position, and then continue to pay out the connecting wire 3 so that the sensor 4 moves into the water, and finally release the two groups of blocks 13, and drive the blocks 13 to clamp the connecting wire 3 by the spring 14, so that the connecting wire 3 and the sensor 4 can be fixed, and then the flow rate of the water flow can be detected by the sensor 4 and the specific value can be fed back to the display screen of the host 2.
