[0037] See also Figure 1 and Figure 2 The flow velocity measuring device of the embodiment of the utility model integrated with the depth scale probe rod 200 comprises a speed meter 100, a probe rod 200 and a protective layer 300. The probe rod 200 is provided with a probe 210, which is electrically connected to the speed meter 100 through a connecting line 110. The probe 210 is used to cooperate with the speed meter 100 to measure the water flow velocity. The surface of the probe rod 200 is provided with a scale mark 220 along the length direction of the probe rod 200. The protective layer 300 is wrapped and connected to the surface of the probe rod 200, and the protective layer 300 is transparent.

[0038] The probe 210 cooperates with the speed meter 100 to measure the water flow rate. The probe rod 200 is provided with a scale mark 220, so that the probe rod 200 allows the user to adjust the depth of the probe rod 200 inserted into the water according to the water depth, so that the scale mark can be directly aligned with the water surface, thereby reading the water depth. A transparent protective layer 300 is provided on the surface of the probe rod 200, which will not block the scale mark 220, but can also protect the scale mark 220, reduce the wear of the scale mark 220, and improve the accuracy and service life of the equipment.

[0039] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The flow velocity measuring device further includes an indicating buoy 400, on which a through hole 410 is provided, the inner diameter of the through hole 410 is larger than the outer diameter of the protective layer 300, and the indicating buoy 400 is slidably sleeved outside the protective layer 300. When the probe 200 is inserted into the water, the indicating buoy 400 floats on the water surface under the action of buoyancy, and the position of the scale mark 220 indicated by the inner circle of the indicating buoy 400 is the water depth. Setting the indicating buoy 400 can reduce the situation of inaccurate readings caused by refraction or reflection of the water surface.

[0040] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The through hole 410 is chamfered to reduce the effect of the thickness of the indicating buoy 400 blocking the indicating scale and affecting the water depth reading.

[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The indicating buoy 400 is provided with an opening 420, and the opening 420 communicates with the through hole 410 and the outside of the indicating buoy 400. The indicating buoy 400 is provided with the opening 420, so that the indicating buoy 400 is easier to be disassembled from the probe 200. The indicating buoy 400 can be disassembled from the probe 200 by staggering the two ends close to the opening 420.

[0042] In some embodiments, see Figure 1 , Figure 2 and Figure 3 , a first retaining ring 430 is provided on the probe rod 200, and the first retaining ring 430 is sleeved on the protective layer 300. The first retaining ring 430 is connected to the protective layer 300 in a damping sliding manner, and the outer diameter of the first retaining ring 430 is greater than the inner diameter of the through hole 410. The first retaining ring 430 is connected to the protective layer 300 in a damping sliding manner. When the first retaining ring 430 is moved, the first retaining ring 430 can wipe the surface of the protective layer 300, improve the transparency of the protective layer 300, and ensure smooth reading of the water depth. The outer diameter of the first retaining ring 430 is greater than the inner diameter of the through hole 410, so that the first retaining ring 430 can limit the moving range of the indicating buoy 400.

[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The probe rod 200 is provided with a second retaining ring 440, which is sleeved on the protective layer 300, and is connected to the protective layer 300 in a damping sliding manner. The outer diameter of the second retaining ring 440 is greater than the inner diameter of the through hole 410, and the first retaining ring 430 and the second retaining ring 440 are located on both sides of the indicating buoy 400. The first retaining ring 430 and the second retaining ring 440 are connected to the protective layer 300 in a damping sliding manner, and the first retaining ring 430 and the second retaining ring 440 are located on both sides of the indicating buoy 400. The first retaining ring 430 is located above the indicating buoy 400, and the second retaining ring 440 is located below the indicating buoy 400, so that the first retaining ring 430 and the second retaining ring 440 can clamp the indicating buoy 400 to ensure that the probe rod 200 measures the water flow rate at a preset depth.

[0044] During measurement, first move the second retaining ring 440 located below the indicating buoy 400 to a position close to the scale mark 220 corresponding to the preset depth, then move the indicating buoy 400 to the scale mark 220 corresponding to the preset depth, then push the second retaining ring 440 to abut the bottom of the indicating buoy 400, and finally push the first retaining ring 430 to abut the top of the indicating buoy 400.

[0045] When fixed water depth measurement is not needed, it is only necessary to move the first retaining ring 430 to the top of the probe rod 200 and the second retaining ring 440 to the bottom of the probe rod 200 .

[0046] In some embodiments, see Figure 1 The scale mark 220 includes a plurality of scale grooves 221, and the plurality of scale grooves 221 are evenly spaced. The scale grooves 221 are directly processed on the surface of the probe rod 200, so that the scale mark 220 is not easy to fall off from the surface of the probe rod 200, and the wear resistance and service life of the scale mark 220 can be increased.

[0047] In some embodiments, see Figure 1 The scale groove 221 is filled with a first coating, and the surface of the probe rod 200 is coated with a second coating, and the colors of the first coating and the second coating are inconsistent. The color of the indicator mark is inconsistent with the color of the probe rod 200 itself, which facilitates the reading of the depth.

[0048] In some embodiments, see Figure 1 and Figure 3 The indicator buoy 400 is coated with a fourth coating, and the color of the fourth coating is inconsistent with the color of the first coating. The color of the indicator mark is inconsistent with the color of the indicator mark, so that the indicator mark is more prominent, which is convenient for depth reading.

[0049] In some embodiments, see Figure 1 and Figure 2 The protective layer 300 includes a third coating, which is coated on the probe rod 200 and is transparent. The third coating can be transparent glue or varnish, which is sprayed on the probe rod 200 to protect the scale mark 220 and improve the wear resistance of the scale mark 220.

[0050] In some embodiments, see Figure 1 and Figure 2 The protective layer 300 includes a sleeve 310, which is transparent and can be detachably sleeved on the surface of the probe 200. The protective layer 300 is provided as the sleeve 310, so that the protective layer 300 and the probe 200 can be easily disassembled and assembled. Moreover, the transparent sleeve 310 is relatively common and has a low cost. After the sleeve 310 is worn, the sleeve 310 can be directly replaced.

[0051] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The probe rod 200 is hollow inside, and a connecting wire 110 is arranged inside the probe rod 200. The connecting wire 110 passes through the probe rod 200 and is electrically connected to the sensor 213.

[0052] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The probe rod 200 is made of a rigid material, such as iron alloy or aluminum alloy, so that the probe rod 200 can remain stable in the water and is not deflected by the water flow, thereby ensuring stability and accuracy in the water.

[0053] In some embodiments, see Figure 1 and Figure 4 The probe 210 includes a bracket 211, a propeller 212 and a sensor 213. The bracket 211 is installed at one end of the probe rod 200. The bracket 211 is arranged in a ring shape and a rotating shaft is arranged on the bracket 211. The sensor 213 is installed on the bracket 211. The propeller 212 is rotatably connected to the rotating shaft of the bracket 211. The sensor 213 is directly opposite to the propeller. The sensor 213 is electrically connected to the speed meter 100 through the connecting line 110. The speed meter 100 is a conventional speed meter 100 in the prior art, and a signal processing circuit is usually installed inside the flow meter. The sensor 213 is responsible for detecting the rotation speed of the propeller 212 and converting it into an electrical signal. The signal processing circuit amplifies, filters and calculates these electrical signals to finally obtain the numerical value of the water flow velocity.

[0054] The working principle of the flow velocity measuring device with integrated depth scale probe of the utility model is as follows:

[0055] 1. When measuring at a preset depth: move the second retaining ring 440 located below the indicating buoy 400 to a position close to the scale mark 220 corresponding to the preset depth, then move the indicating buoy 400 to the scale mark 220 corresponding to the preset depth, then push the second retaining ring 440 to abut the bottom of the indicating buoy 400, and finally push the first retaining ring 430 to abut the top of the indicating buoy 400, insert the probe rod 200 into the water, and start the speed meter 100 to measure the water flow rate.

[0056] 2. When measuring at an uncertain depth, move the second baffle ring 440 to the lowermost end of the probe rod 200, move the first baffle ring 430 to the uppermost end of the probe rod 200, insert the probe rod 200 into the water, start the speed meter 100 to measure the water flow rate, and the reading of the scale mark 220 corresponding to the position indicated by the indicator buoy 400 is the real-time depth.
