[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] The invention provides a flow measuring device for water conservancy projects.

[0052] Please refer to Figure 1 to Figure 2 In one embodiment of the present invention, the flow measuring device for water conservancy projects comprises: a flow measuring vehicle 1, a lifting device 2, a flow measuring device 3, a slide 4, a shaking device 5, a flow measuring room 10 and a mounting column 20;

[0053] The flow measuring room 10 and the installation column 20 are installed on both sides of the river channel, the slideway 4 is installed between the flow measuring room 10 and the installation column 20, and is suspended above the river channel, the flow measuring vehicle 1 is arranged on the slideway 4, the lifting device 2 is installed on the flow measuring vehicle 1, and the flow measuring device 3 can be movably installed at the output end of the lifting device 2;

[0054] When measuring the flow, the flow measuring vehicle 1 moves along the slide 4 to a preset flow measuring position, and the lifting device 2 lowers the flow measuring device 3 into the river; when floating objects are attached to the flow measuring device 3, the lifting device 2 lifts the flow measuring device 3 above the river, and the shaking device 5 shakes the flow measuring device 3 to make the floating objects fall off.

[0055] During the detection process, when there are floating objects attached to the flow measuring device 3, the lifting device 2 lifts the flow measuring device 3 to above the water flow, and then the shaking device 5 shakes the flow measuring device 3 to shake off the floating objects attached to the flow measuring device 3, so that the detection can continue, realizing the function of automatically shaking off the attached floating objects.

[0056] During detection, the flow measuring vehicle 1 drives the flow measuring device 3 to move to different flow measuring points. After detection in turn, the lifting device 2 retracts the flow measuring device 3, and then the flow measuring vehicle 1 moves to the inside of the flow measuring room 10. The flow measuring vehicle 1 can be assembled with the corresponding charging equipment inside the flow measuring room 10 for charging.

[0057] In this embodiment, the flow measuring device 3 may be a propeller flow meter or an acoustic Doppler flow profiler or other equipment that needs to be inserted under the water flow to detect the flow velocity.

[0058] In one embodiment, a sensor can be installed at the bottom of the flow measuring vehicle 1 or on the flow measuring device 3 to assist in detecting whether there are floating objects attached, wherein the sensor can be a camera, and when installed on the flow measuring device 3, it can also be a radar sensor or a laser sensor, etc., and the sensor faces the flow measuring end of the flow measuring device 3.

[0059] In another embodiment, it is also possible to determine that floating objects are attached based only on the sudden change in the flow velocity of the water flow detected by the flow measuring device 3, and then perform a shaking and cleaning operation.

[0060] See also Figure 3 and Figure 4 In one embodiment, the shaking device 5 includes a horizontal driving device 51, a telescopic rod 52 and a connecting frame 53. The horizontal driving device 51 is installed on the flow measuring vehicle 1, the top end of the telescopic rod 52 is installed at the output end of the horizontal driving device 51, and the bottom end of the telescopic rod 52 is connected to the flow measuring device 3 through the connecting frame 53. The horizontal driving device 51 is used to drive the telescopic rod 52 to move back and forth.

[0061] When floating objects are attached to the flow measuring device 3, the lifting device 2 lifts the flow measuring device 3 to above the water flow, and the horizontal driving device 51 drives the telescopic rod 52 to vibrate horizontally back and forth. The telescopic rod 52 drives the flow measuring device 3 to vibrate horizontally back and forth through the connecting frame 53, thereby shaking off the attached objects on the flow measuring device 3, thereby realizing the function of cleaning the attached objects.

[0062] The reciprocating vibration is carried out in a horizontal direction, that is, in a direction parallel to the slideway 4 .

[0063] The horizontal driving device 51 is installed on the flow measuring vehicle 1. When the lifting device 2 lifts the flow measuring device 3 by retracting and releasing the traction rope 24, the flow measuring device 3 can drive the traction rope 24 to swing simultaneously while vibrating, so that floating objects attached to the traction rope 24 can be cleaned at the same time.

[0064] In another embodiment, the flow measuring device 3 can be installed at the output end of the lifting device 2 through a fixed frame, and a sliding sleeve is provided on the flow measuring device 3, which is slidably arranged on the fixed frame in the horizontal direction. The horizontal driving device 51 is installed on the fixed frame, and the output end of the horizontal driving device 51 is connected to the sliding sleeve or the flow measuring device 3, so as to drive the flow measuring device 3 to reciprocate in the horizontal direction.

[0065] See also Figure 8 The telescopic rod 52 includes a plurality of connecting tubes 521 , the diameters of the plurality of connecting tubes 521 are successively reduced, the plurality of connecting tubes 521 are successively sleeved, and adjacent connecting tubes 521 are connected by sliding keys.

[0066] By configuring the telescopic rod 52 as a plurality of connecting tubes 521 with successively decreasing diameters, and sequentially sleeve-connecting and sliding-keying them, it is possible to ensure that the length of the telescopic rod 52 after extension meets the requirement of the distance that the flow measuring device 3 descends when extended under the water flow. At the same time, after being retracted, the overall length of the telescopic rod 52 can be reduced, so that the flow measuring device 3 can be closer to the flow measuring vehicle 1.

[0067] In one embodiment, a slide groove is provided on the inner wall of the connecting tube 521, and a slide key is correspondingly installed on the outside. When adjacent connecting tubes 521 are assembled, the slide key slides into the slide groove to form a slide key fit.

[0068] In another embodiment, each connecting tube 521 is configured as a frustum, that is, the diameters at both ends are different, and a plurality of connecting tubes 521 are connected to form a "fishing rod" structure.

[0069] See also Figure 3 and Figure 4 The flow measuring equipment for water conservancy projects also includes an angle adjustment device 6, which includes a lifting cylinder 61, an assembly frame 62 and a lifting device 63. The lifting cylinder 61 is installed at the output end of the horizontal driving device 51, and the assembly frame 62 is installed at the output end of the lifting cylinder 61. The lifting device 63 is installed on the assembly frame 62, and the output end of the lifting device 63 is connected to the connecting pipe 521 with the smallest diameter in the telescopic rod 52.

[0070] In this embodiment, the bottom end of the connecting tube 521 with the smallest diameter in the telescopic rod 52 is eccentrically connected to the flow measuring device 3 through the connecting frame 53, and the connecting frame 53 is connected to the part of the flow measuring device 3 near the tail, wherein the head is the part that first acts on the water flow after the flow measuring device 3 is located inside the water flow.

[0071] Please refer to Fig. 9 (9a) to Fig. 9In (9c), when the floating objects attached to the flow measuring device 3 need to be cleaned, the lifting device 2 lifts the flow measuring device 3 to the top of the river, and at the same time, the lifting device 63 lifts the connecting pipe 521 at the bottom of the telescopic rod 52, that is, the connecting pipe 521 with the smallest diameter, so that the bottom connecting pipe 521 and the flow measuring device 3 are kept at the same height, and then the lifting cylinder 61 drives the lifting device 63 to follow the lifting through the assembly frame 62. At this time, the lifting device 63 continues to lift the connecting pipe 521 at the bottom of the telescopic rod 52, and the connecting pipe 521 lifts the tail of the flow measuring device 3 through the connecting frame 53, so that the flow measuring device 3 is inclined. Fig. 9 (9c) and Fig.10 .

[0072] At this time, the horizontal driving device 51 drives the telescopic rod 52 to vibrate back and forth, and the telescopic rod 52 drives the inclined flow measuring device 3 to follow the vibration through the connecting frame 53, so that the attached floating objects can be shaken off more easily.

[0073] The connecting frame 53 includes a connecting plate and a connecting shaft. The connecting plate is installed at the bottom end of the connecting pipe 521 with the smallest diameter. One end of the connecting shaft is connected to the flow measuring device 3, and the other end is rotatably connected to the connecting plate.

[0074] See also Figure 3 and Figure 4 Specifically, the flow measuring vehicle 1 includes a body 11, a driving wheel 12 and a driven wheel 13, the driving wheel 12 and the driven wheel 13 are installed on the body 11 at intervals, and the driving wheel 12 is used to drive the body 11 to move;

[0075] The horizontal driving device 51 and the lifting device 2 are both installed inside the vehicle body 11, and the bottom of the vehicle body 11 is opened.

[0076] The driving wheel 12 cooperates with the driven wheel 13 to drive the vehicle body 11 to move along the slideway 4, thereby driving the lifting device 2, the shaking device 5 and the flow measuring device 3 to move to different flow measuring points.

[0077] The flow measuring vehicle 1 also includes a battery, a control circuit, a charging circuit, a wireless communication module, etc., to realize the functions of regular flow measurement and data transmission of the flow measuring vehicle 1.

[0078] There are no less than two driven wheels 13, which are installed on both sides of the vehicle body 11;

[0079] Please refer again Figure 3 and Figure 4Specifically, the driving wheel 12 includes a driving shaft 121, a walking motor 123, a bracket, a gear set and two rollers 122. The driving shaft 121 passes through the vehicle body 11 and is rotatably connected to the vehicle body 11. The two rollers 122 are respectively installed at both ends of the driving shaft 121. The walking motor 123 is installed inside the vehicle body 11 through the bracket. The walking motor 123 is transmission-connected to the driving shaft 121 through a gear set.

[0080] The travel motor 123 drives the drive shaft 121 to rotate clockwise or counterclockwise through the gear set, and the drive shaft 121 drives the two rollers 122 to rotate, thereby driving the flow measuring vehicle 1 forward and backward, and driving the flow measuring device 3 to move to different flow measuring points.

[0081] See also Figure 3 As a preferred embodiment, the gear set includes a main gear 126 and a slave gear 127, the main gear 126 and the slave gear 127 are respectively mounted on the output shaft of the travel motor 123 and the drive shaft 121, and the main gear 126 and the slave gear 127 are meshed, the drive wheel 12 also includes a convex shaft 128, the convex shaft 128 is eccentrically mounted on the main gear 126, the bracket includes a mounting frame 125 and a plurality of slide bars 124, a plurality of the slide bars 124 are installed at intervals inside the vehicle body 11, the mounting frame 125 is slidably mounted on the slide bars 124, and the travel motor 123 is mounted on the mounting frame 125;

[0082] The horizontal driving device 51 includes a fixed plate 511, a sliding plate 512, a connecting arm 513 and a driving frame 514. The fixed plate 511 is installed inside the vehicle body 11 and is located between the driving shaft 121 and the telescopic rod 52. The sliding plate 512 is slidably installed on the fixed plate 511. The driving frame 514 is suspended above the convex shaft 128. The driving frame 514 is connected to the sliding plate 512 through the connecting arm 513.

[0083] The lifting cylinder 61 is installed on the sliding plate 512, and one end of the assembly frame 62 is connected to the mounting frame 125 along the horizontal direction by a sliding key.

[0084] When the travel motor 123 and the main gear 126 are in the walking state, the main gear 126 is meshed with the slave gear 127, and the convex shaft 128 is located below the driving frame 514. At this time, the travel motor 123 drives the main gear 126 to rotate, and the main gear 126 drives the driving shaft 121 to rotate through the slave gear 127, and the driving shaft 121 drives the two rollers 122 to rotate, thereby driving the flow measuring vehicle 1 to move;

[0085] After the flow measuring vehicle 1 drives the flow measuring device 3 to move to the corresponding flow measuring point, during the flow measuring process, when floating objects are attached to the flow measuring device 3 and need to be shaken off, after the flow measuring device 3 is lifted to the water surface, the lifting cylinder 61 lifts the assembly frame 62, and the lifting device 63 is lifted to make the connecting pipe 521 at the bottom lift the flow measuring device 3 to make it tilted, and the assembly frame 62 drives the mounting frame 125 to be lifted, and the mounting frame 125 lifts the travel motor 123, and the travel motor 123 drives the main gear 126 to be lifted, so that the convex shaft 128 on the main gear 126 is inserted into the driving frame 514 and separated from the slave gear 127;

[0086] At this time, the travel motor 123 and the main gear 126 enter a shaking state. Fig.11 (11a) and Fig.11 In (11b), the travel motor 123 drives the main gear 126 to rotate again, and the main gear 126 drives the convex shaft 128 to slide along the inside of the driving frame 514, and drives the driving frame 514 to move back and forth left and right, and the driving frame 514 drives the sliding plate 512 to move back and forth through the connecting arm 513, and the sliding plate 512 drives the flow measuring device 3 to move back and forth through the telescopic rod 52, thereby driving the flow measuring device 3 to vibrate and shake off the attached floating objects.

[0087] That is, in the process of adjusting the inclination angle of the flow measuring device 3 by using the lifting cylinder 61, the state switching of the travel motor 123 and the main gear 126 is completed, so that the travel motor 123 and the main gear 126 can drive the flow measuring vehicle 1 to move, and can also drive the flow measuring device 3 to shake, clean up attachments, and simplify the demand for driving equipment.

[0088] Subsequently, the lifting cylinder 61 lowers the assembly frame 62, and the telescopic rod 52 follows the lowering, and the flow measuring device 3 returns to the original angle. At the same time, the mounting frame 125 follows the lowering, driving the travel motor 123 to lower, so that the main gear 126 is meshed with the slave gear 127 again.

[0089] When the sliding plate 512 moves back and forth, it drives the lifting cylinder 61 and the lifting device 63 to move accordingly.

[0090] The fixed plate 511 is provided with an opening, and sliding arms are provided on both sides of the opening on the fixed plate 511. One end of the sliding arm is fixed to the fixed plate 511 through a connecting ear, and both sides of the sliding plate 512 are correspondingly sleeved on the sliding arms located on both sides of the opening to form a sliding assembly;

[0091] The lifting cylinder 61 is located in the opening. The lifting cylinder 61 is installed on the sliding plate 512 , and its output shaft passes through the sliding plate 512 and is connected to the assembly frame 62 .

[0092] When the flow measuring vehicle 1 is in the initial state, that is, when it is retracted into the flow measuring room 10, the convex shaft 128 is just located below the driving frame 514. Figure 6 As shown, by setting each time the flow measuring vehicle 1 moves to the flow measuring point, the travel motor 123 drives the main gear 126 to rotate an integer number of circles and then stop, thereby ensuring that after stopping, the convex shaft 128 is still aligned with the driving frame 514, which is convenient for subsequent assembly.

[0093] A plurality of cams 128 may be disposed around the main gear 126 . For example, two cams 128 may be symmetrically disposed. When the main gear 126 approaches the flow measurement point, the main gear 126 only needs to rotate half a circle and stop to ensure that one cam 128 is located below the driving frame 514 .

[0094] When the corresponding travel motor 123 is in a shaking state, the travel motor 123 starts and stops for an integer number of circles, so that the main gear 126 can mesh with the slave gear 127 again later.

[0095] The lifting cylinder 61 is a pneumatic cylinder, a hydraulic cylinder or an electric push cylinder.

[0096] Preferably, a support block is installed at the bottom end of the sliding rod 124.

[0097] By setting a support block at the bottom end of the slide rod 124, when the main gear 126 is engaged with the slave gear 127, the bottom end of the mounting frame 125 is located on the support block, and the support block assists in supporting the mounting frame 125, that is, supporting the travel motor 123, thereby improving the stability of the structure.

[0098] The number of the sliding rods 124 is preferably four, and the four corners of the mounting frame 125 are correspondingly sleeved on the sliding rods 124 .

[0099] See also Figure 7 In one embodiment, a strip hole 9 is opened on the mounting frame 125, and the other end of the assembly frame 62 is sleeved on the mounting frame 125 through the strip hole 9, so that the assembly frame 62 and the mounting frame 125 form a sliding key connection.

[0100] The assembly frame 62 is sleeved on one side of the mounting frame 125 and a strip opening is correspondingly opened, so that there is space for mutual movement between the assembly frame 62 and the mounting frame 125 in the horizontal direction, so that when the travel motor 123 and the main gear 126 are in a shaking state, the sliding plate 512 drives the assembly frame 62 to vibrate reciprocatingly through the lifting cylinder 61, and the assembly frame 62 can move reciprocatingly relative to the mounting frame 125.

[0101] In another embodiment, slide rails are provided on both sides of the mounting frame 125, one side of the assembly frame 62 is sleeved on the mounting frame 125 by opening an opening, and corresponding slide grooves are provided on both sides of the opening to be slidably connected to the slide rails, so that the assembly frame 62 and the mounting frame 125 form a sliding key connection.

[0102] See also Figure 5The flow measuring device for water conservancy projects also includes a stop member 7, which includes a mounting arm 71 and a stop block 72. One end of the mounting arm 71 is connected to the assembly frame 62, and the other end of the mounting arm 71 passes through the vehicle body 11 through a sliding hole 111 and is connected to the stop block 72, and the stop block 72 is suspended below the slide 4.

[0103] When the travel motor 123 and the main gear 126 switch from the walking state to the shaking state, during the process of the lifting cylinder 61 lifting the assembly frame 62, the assembly frame 62 drives the stop block 72 to follow the lifting through the mounting arm 71. When the state switching is completed, the stop block 72 abuts against the bottom of the slide 4, thereby limiting the position of the flow measuring vehicle 1 at this time to avoid displacement of the flow measuring vehicle 1. The roller 122 will not rotate, that is, the slave gear 127 will not rotate, thereby ensuring that subsequently, when the travel motor 123 and the main gear 126 switch from the shaking state to the walking state, the main gear 126 can mesh with the slave gear 127 again.

[0104] A rubber pad is provided on one side of the stop block 72 facing the slideway 4 to increase the friction when the stop block 72 abuts against the slideway 4 .

[0105] See also Figure 3 and Figure 4 In one embodiment, the lifting device 2 includes a mounting plate 21, a lifting motor 22, a first winding wheel 23 and a traction rope 24. The lifting motor 22 is mounted on the flow measuring vehicle 1 through the mounting plate 21. One end of the first winding wheel 23 is mounted on the output end of the lifting motor 22. One end of the traction rope 24 is mounted on the first winding wheel 23, and the other end is connected to the flow measuring device 3.

[0106] The lifting device 63 includes a second winding wheel 631, an adjusting rope 632 and an assembly frame 633. One end of the second winding wheel 631 is rotatably mounted on one end of the assembly frame 62. The assembly sleeve 26 is mounted on the other end of the first winding wheel 23. One end of the adjusting rope 632 is mounted on the second winding wheel 631. The other end of the adjusting rope 632 is connected to the connecting pipe 521 with the smallest diameter in the telescopic rod 52.

[0107] The lifting device 2 also includes an assembly sleeve 26 , which is installed on the side of the first winding wheel 23 facing the second winding wheel 631 . The first winding wheel 23 and the second winding wheel 631 are concentrically arranged, and the assembly frame 633 is inserted into the interior of the assembly sleeve 26 .

[0108] Among them, when the floating objects attached to the flow measuring device 3 need to be shaken off, when the lifting device 2 lifts the flow measuring device 3 out of the water, the lifting motor 22 drives the first winding wheel 23 to rotate, and the traction rope 24 is reeled in, thereby lifting the flow measuring device 3. At the same time, the first winding wheel 23 drives the assembly frame 633 to rotate through the assembly set 26, and the assembly frame 633 drives the second winding wheel 631 to rotate, reeling in the adjusting rope 632, and lifting the connecting pipe 521 at the bottom, so that the bottom connecting pipe 521 and the flow measuring device 3 are synchronously raised, and the bottom end height of the connecting pipe 521 is kept flush with the flow measuring device 3. At this time, when the lifting cylinder 61 lifts the assembly frame 62 to drive the second winding wheel 631 to lift, the bottom connecting pipe 521 can be lifted again by the adjusting rope 632, and the connecting pipe 521 drives one end of the flow measuring device 3 to be lifted through the connecting frame 53, so that the flow measuring device 3 is tilted.

[0109] That is, multiple driving devices are not required to drive the first winding wheel 23 and the second winding wheel 631 .

[0110] See also Figure 6 A positioning frame 25 is connected to the bottom of the mounting plate 21 , and a positioning hole is opened at one end of the positioning frame 25 away from the mounting plate 21 . The traction rope 24 passes through the positioning hole and is connected to the flow measuring device 3 .

[0111] The positioning frame 25 can limit the traction rope 24 in the horizontal direction.

[0112] The bottom end of the traction rope 24 is connected to two branch ropes through a connecting ring. The two branch ropes are respectively connected to two ends of the flow measuring device 3. The two branch ropes can better maintain the level of the flow measuring device 3.

[0113] In another embodiment, driving motors may be provided to drive the first winding wheel 23 and the second winding wheel 631 to rotate respectively.

[0114] In this embodiment, the lifting motor 22 can also be installed on the flow measuring device 3 through a support frame, the first winding wheel 23 is installed at the output end of the lifting motor 22, and the traction rope 24 connects the first winding wheel 23 and the vehicle body 11.

[0115] See also Figure 6 and Fig. 9 A positioning rod 8 is installed inside the vehicle body 11 and is suspended above the assembly frame 633 .

[0116] When the flow measuring device 3 is adjusted to an inclination angle, the assembly frame 633 moves upward and separates from the assembly sleeve 26. The assembly frame 633 is sleeved on the positioning rod 8, thereby preventing the second winding wheel 631 from rotating when the connecting pipe 521 at the bottom is lifted by the winding adjustment rope 632, thereby preventing the connecting pipe 521 from being lifted smoothly and the assembly frame 633 from being assembled with the assembly sleeve 26 again.

[0117] When the assembly frame 633 and the assembly sleeve 26 are not completely separated, the positioning rod 8 begins to be inserted into the assembly frame 633 , so that the axial limitation of the assembly frame 633 is continuous.

[0118] When the flow measuring device 3 is shaken to remove attachments, the sliding plate 512 drives the lifting cylinder 61 to move back and forth, and the lifting cylinder 61 drives the second winding wheel 631 to follow the reciprocating movement through the assembly frame 62. At this time, the positioning rod 8 slides relatively horizontally along the inside of the assembly frame 633.

[0119] The working principle of the flow measuring device for water conservancy projects provided by the present invention is as follows:

[0120] During the detection process, when floating objects are attached to the flow measuring device 3 and need to be cleaned, the lifting device 2 lifts the flow measuring device 3 to the top of the water flow;

[0121] Please refer to Fig. 9 (9a) to Fig. 9 At the same time, the lifting device 63 lifts the connecting pipe 521 at the bottom of the telescopic rod 52, so that the connecting pipe 521 at the bottom is kept at the same height as the flow measuring device 3, and then the lifting cylinder 61 drives the lifting device 63 to follow the lifting through the assembly frame 62. At this time, the lifting device 63 continues to lift the connecting pipe 521 at the bottom of the telescopic rod 52, and the connecting pipe 521 lifts the tail of the flow measuring device 3 through the connecting frame 53, so that the flow measuring device 3 is inclined. Fig. 9 (9c) and Fig.10 .

[0122] Then the horizontal driving device 51 drives the telescopic rod 52 to vibrate back and forth, and the telescopic rod 52 drives the inclined flow measuring device 3 to vibrate along through the connecting frame 53, so that the attached floating objects can be shaken off more easily.

[0123] The specific working principle of the shaking device 5 and the flow measuring vehicle 1 is as follows: when the traveling motor 123 and the main gear 126 are in the traveling state, the main gear 126 is meshed with the slave gear 127, and the convex shaft 128 is located below the driving frame 514. At this time, the traveling motor 123 drives the main gear 126 to rotate, and the main gear 126 drives the driving shaft 121 to rotate through the slave gear 127, and the driving shaft 121 drives the two rollers 122 to rotate, thereby driving the flow measuring vehicle 1 to move;

[0124] After the flow measuring vehicle 1 drives the flow measuring device 3 to move to the corresponding flow measuring point, during the flow measuring process, when floating objects are attached to the flow measuring device 3 and need to be shaken off, after the flow measuring device 3 is lifted to the water surface, the lifting cylinder 61 lifts the assembly frame 62, and the lifting device 63 is lifted to make the connecting pipe 521 at the bottom lift the flow measuring device 3 to make it tilted, and the assembly frame 62 drives the mounting frame 125 to be lifted, and the mounting frame 125 lifts the travel motor 123, and the travel motor 123 drives the main gear 126 to be lifted, so that the convex shaft 128 on the main gear 126 is inserted into the driving frame 514 and separated from the slave gear 127;

[0125] At this time, the travel motor 123 and the main gear 126 enter a shaking state. Fig.11 (11a) and Fig.11 In (11b), the travel motor 123 drives the main gear 126 to rotate again, and the main gear 126 drives the convex shaft 128 to slide along the inside of the driving frame 514, and drives the driving frame 514 to move back and forth left and right, and the driving frame 514 drives the sliding plate 512 to move back and forth through the connecting arm 513, and the sliding plate 512 drives the flow measuring device 3 to move back and forth through the telescopic rod 52, thereby driving the flow measuring device 3 to vibrate and shake off the attached floating objects.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
