[0024] Embodiment: As Figures 1 to 4 shown, a portable flow measurement rod 3 includes a top cover 1, a storage box 2, a measurement rod 3, and a paddle 4. Two cross columns 6 are installed on the top of the top cover 1. An "L"-shaped mounting block 5 is installed on the outer wall surface of each cross column 6. A rotating shaft 7 is rotatably connected between the upper and lower inner wall surfaces of the mounting block 5.

A fastening part 11 for fixing the moving part 10 is provided on the top of the top cover 1. A storage cavity 12 is opened on the front wall surface of the top cover 1;

[0025] Specifically, the front baffle plate 8 and the rear enclosing plate 9 can play an enclosing and limiting role for the measuring rod 3. Compared with the manual gripping method, it can not only reduce the soreness of the operator's arm when performing the measurement work, but also make the measuring rod 3 always remain in a vertical position when in use, effectively ensuring the accuracy of the measurement data; the driving moving part 10 can drive the cross column 6 to move horizontally, so that the mounting block 5 can be moved to the outside of the storage box 2, so as to play a role in limiting and fixing the measuring rod 3; the balancing support part 13 can rotate when the cross column 6 is moved out, so as to play a supporting effect on the cross column 6, ensure the stability of the cross column 6 when in use, avoid the storage box 2 from tipping over due to the uneven weight on both sides, and ensure the smooth progress of the measurement work; the storage cavity 12 can play a temporary storage effect for all the components arranged on the top cover 1, to avoid dust accumulation when not in use, or damage caused by external force collision;

[0026] like Figure 2 As shown, the front baffle plate 8 and the rear enclosure plate 9 are arranged perpendicularly to each other on the outer wall surface of the rotating shaft 7, and the wall surface of the front baffle plate 8 and the rear enclosure plate 9 on one side close to the measuring rod 3 is provided with anti-slip grooves;

[0027] Specifically, by providing the anti-slip grooves, the stability of the measuring rod 3 placed between the front baffle plate 8 and the rear surround plate 9 can be enhanced, preventing the measuring rod 3 from sliding downward during use.

[0028] like Figure 1 As shown, the moving part 10 includes a fixed platform 101, the top of the top cover 1 is provided with the fixed platform 101, the top of the fixed platform 101 is installed with a gear 102, a wall surface of one side of the two horizontal columns 6 away from each other is connected with a plurality of equidistantly distributed protrusions 103, a stabilizing cavity is formed between every two protrusions 103, the connection between the gear 102 and the stabilizing cavity is meshing, and the inner cavity of the fixed platform 101 is provided with a motor whose output end is connected to the input end of the gear 102;

[0029] Specifically, the driving gear 102 can drive the cross column 6 to move in the horizontal direction with the cooperation of the stabilizing cavity, so that the mounting block 5 can be moved to the outside of the storage box 2.

[0030] like Figure 1 As shown, the bottom of the fixing platform 101 is connected to two engaging columns 1102, and the top of the top cover 1 is provided with an engaging groove 1101 for accommodating the sliding of the gear 102;

[0031] In order to ensure the firmness of the connection between the snap-fit ​​groove 1101 and the snap-fit ​​column 1102, a rubber pad is bonded to the outer wall surface of the snap-fit ​​column 1102;

[0032] Specifically, by inserting the engaging column 1102 into the engaging groove 1101 , the purpose of installing the fixing platform 101 on the top of the top cover 1 can be achieved, and the structure is simple and easy to operate.

[0033] like Figure 1 As shown, a horizontal slider is connected to the bottom of the horizontal column 6, and a sliding groove 1103 for the horizontal slider to slide is provided on the top of the fixed platform 101;

[0034] Specifically, the horizontal sliding block and the sliding groove 1103 can support the bottom of the horizontal column 6 when the horizontal column 6 moves horizontally, thereby improving the stability of the horizontal column 6 when moving.

[0035] like Figure 3 As shown, the balance support portion 13 includes a storage cavity 1301. The storage cavity 1301 is opened at the bottom of the horizontal column 6. A rotating shaft 1302 is rotatably connected inside the storage cavity 1301. A lower support column 1303 is detachably connected to the outer wall surface of the rotating shaft 1302.

[0036] Specifically, when the rotating shaft 1302 is moved to the outside of the storage box 2, the lower support column 1303 can be driven to rotate under the action of gravity, thereby supporting the bottom of the horizontal column 6, ensuring the stability of the horizontal column 6 when in use and the stability of the storage box 2 when placed on the ground (in actual use, the lower support column 1303 of an appropriate length can be selected as needed).

[0037] When in use, the operator can place the storage box 2 on the bank of the water source to be measured, then take out the required parts from the storage chamber 12, and then insert the engaging column 1102 into the engaging groove 1101, so as to achieve the purpose of installing the fixing platform 101 on the top of the top cover 1, and then drive the gear 102 to drive the horizontal column 6 to move in the horizontal direction with the cooperation of the stabilizing chamber, so that the mounting block 5 can be moved to the outside of the storage box 2. When moving, the rotating shaft 1302 needs to be moved to the outside of the storage box 2. When the gear 102 is stopped, the lower support column 1303 can be driven to rotate under the action of gravity when the rotating shaft 1302 is moved to the outside of the storage box 2, so as to support the bottom of the horizontal column 6.

[0038] Then the measuring rod 3 is taken out from the storage box 2 for assembly, and then the assembled measuring rod 3 is moved to one side of the mounting block 5. When the outer wall surface of the measuring rod 3 contacts the outer wall surface of the rotating shaft 7, the rotating shaft 7 can rotate accordingly, so that the measuring rod 3 can be moved to the side close to the mounting block 5. The rear surrounding plate 9 made of elastic silicone material can be deformed according to the shape of the measuring rod 3, so that it can cooperate with the front baffle 8 to play a surrounding limiting and fixing role for the measuring rod 3, thereby ensuring the stability of the measuring rod 3 when in use.

[0039] In summary, the front baffle plate 8 and the rear enclosing plate 9 can play an enclosing and limiting role on the measuring rod 3. Compared with the manual holding method, it can not only reduce the soreness of the operator's arm when performing measurement work, but also make the measuring rod 3 always keep a vertical position when in use, effectively ensuring the accuracy of the measurement data; the driving moving part 10 can drive the cross column 6 to move horizontally, so that the mounting block 5 can be moved to the outside of the storage box 2, so as to play a role in limiting and fixing the measuring rod 3;

[0040] The balancing support portion 13 is capable of rotating when the cross column 6 is removed, thereby supporting the cross column 6 and ensuring the stability of the cross column 6 during use, thereby preventing the storage box 2 from tipping over due to uneven weights on both sides, and ensuring the smooth progress of the measurement work; the storage cavity 12 is capable of temporarily storing all components arranged on the top cover 1, thereby preventing dust accumulation when not in use, or damage caused by external force collision.
