[0032] Reference Figures 1 to 5 In one embodiment of the utility model, a portable water flow velocity measuring device for water conservancy projects includes:

[0033] A main floating plate 100, serving as a supporting base, wherein the density of the main floating plate 100 is 0.1 to 0.8 times the density of water;

[0034] Two guide plates 200 are arranged on the lower surface of both ends of the main floating plate 100 in the width direction, and the length direction of the guide plates 200 is consistent with the length direction of the main floating plate 100;

[0035] A water flow velocity measuring unit 300 is disposed on the lower surface of the main floating board 100, and the measuring direction of the water flow velocity measuring unit 300 is consistent with the length direction of the main floating board 100;

[0036] A plane bearing assembly 400, the inner wall of which is connected to the upper surface of the main floating plate 100;

[0037] A bearing cover 500 is connected to the outer periphery of the plane bearing assembly 400 to wrap the upper surface of the plane bearing assembly 400, and the bearing cover 500 and the main floating plate 100 are relatively rotatable;

[0038] The sleeve 600 is hinged to the outer surface of the bearing cover 500 , and one end of the sleeve 600 away from the bearing cover 500 is an open installation opening.

[0039] In the prior art, when a soft rope is connected, it is difficult to ensure the position of the flow measurement main structure, and it is also difficult to ensure the angle of the flow measurement main structure; when a hard rod is connected, the angle of the flow measurement main structure is difficult to ensure and may require a long time of handholding.

[0040] In the utility model, when the measuring device is in use, the up and down directions are fixed, so a certain direction indication is performed in an up and down manner. The main floating board 100 serves as a supporting base, and the density of the main floating board 100 is 0.1 to 0.8 times the density of water. When in use, the main floating board 100 is parallel to the water surface, thereby ensuring that the angle of the measuring device in the vertical direction is accurate. The material of the main floating board 100 can be various types of plastics or foamed plastics, etc. It should be noted that the main floating board 100 does not necessarily need to float. Under certain circumstances, the main floating board 100 can also be pressed into the water flow by an external structure for use. At this time, the main floating board 100 plays a role of diversion, and can also ensure that the angle of the measuring device in the vertical direction is accurate.

[0041] Two guide plates 200 are arranged on the lower surface of both ends of the main floating plate 100 in the width direction, and the length direction of the guide plates 200 is consistent with the length direction of the main floating plate 100. Through the function of the guide plates 200, the horizontal angle of the measuring device can be guaranteed to be accurate. The number of guide plates 200 is two, which can form a better diversion effect. During use, the direction consistency between the measuring device and the water flow is high; at the same time, the guide plates 200 can protect the water flow velocity measuring part 300 from damage by external impact to a certain extent. In some cases, the guide plates 200 can be used as a storage.

[0042] The water flow velocity measuring unit 300 is disposed on the lower surface of the main floating board 100, and the measuring direction of the water flow velocity measuring unit 300 is consistent with the length direction of the main floating board 100. The test type of the water flow velocity measuring unit 300 is not important, and it can be a propeller type or an ultrasonic type, etc. The water flow velocity measuring unit 300 can read the data in the water flow velocity measuring unit 300 after completing the test, and can also read the relevant data by wired or wireless means.

[0043] The inner wall of the plane bearing assembly 400 is connected to the upper surface of the main floating plate 100. The plane bearing assembly 400 can perform the bearing function in the horizontal direction, thereby ensuring that the main floating plate 100 can rotate in the horizontal direction during the use of the measuring device.

[0044] The bearing cap 500 is connected to the outer periphery of the plane bearing assembly 400 and wraps the upper surface of the plane bearing assembly 400. The bearing cap 500 and the main floating plate 100 are relatively rotatable. The bearing cap 500 plays a transitional role and forms a fixed foundation for the subsequent sleeve 600. At the same time, the bearing cap 500 wraps the upper surface of the plane bearing assembly 400, so the bearing cap 500 can protect the plane bearing assembly 400. During use, the plane bearing assembly 400 will not be affected by abnormal external environment.

[0045] The sleeve 600 is hinged to the outer surface of the bearing cover 500, and the end of the sleeve 600 away from the bearing cover 500 is an open installation opening. The installation opening is the installation base of the external rod-shaped structure. In certain cases, the measuring device can be adapted to its own telescopic rod, but it can also find a relevant rod-shaped structure at the relevant site for temporary connection.

[0046] During use, the sleeve 600 is hinged with the bearing cover 500, so that the sleeve 600 will not limit the swing of the main floating board 100, and the angle of the main floating board 100 can be guaranteed. The setting of the plane bearing assembly 400 enables the main floating board 100 to rotate in the horizontal direction, so that the measuring device can adapt to the direction of the water flow.

[0047] In summary, the sleeve 600 is hinged with the bearing cover 500, and the sleeve 600 will not limit the swing of the main floating plate 100. The main floating plate 100 is parallel to the water surface when in use, thereby ensuring that the angle of the measuring device in the vertical direction is accurate; two guide plates 200 are arranged on the lower surface of the two ends of the width direction of the main floating plate 100. Through the action of the guide plates 200, the horizontal angle of the measuring device can be guaranteed to be accurate. The setting of the plane bearing assembly 400 enables the main floating plate 100 to rotate in the horizontal direction, so that the measuring device can adapt to the direction of the water flow; at the same time, the guide plates 200 can protect the water flow velocity measuring part 300 from being damaged by external impact to a certain extent.

[0048] Reference Figures 1 to 4 In one embodiment, the measuring device further comprises two end covers 700, which are respectively hinged at both ends of the main floating board 100 in the length direction, and the density of the end covers 700 is 0.1 to 0.8 times the density of water, wherein when the end covers 700 are at the bottom, they are combined with the two guide plates 200; when the end covers 700 are at the top, they are arranged parallel to the main floating board 100.

[0049] In this embodiment, when the end cover 700 is turned up, it can provide an auxiliary floating effect during use; and when the end cover 700 is turned down, the end cover 700 can be combined with the guide plate 200 to form a box body to accommodate the water flow velocity measuring part 300. In some embodiments, a cover body can also be provided, and the cover body, the end cover 700, the guide plate 200 and the main floating plate 100 can form a box body. At this time, in the storage state, the entire measuring device can form a box body, and the plane bearing assembly 400, the bearing cover 500 and the sleeve 600 can also be placed in the above-mentioned box body. The material of the end cover 700 can be various types of plastics or foamed plastics.

[0050] In one embodiment, the end cover 700 is fixed when it is arranged parallel to the main floating board 100 .

[0051] In this embodiment, when the main floating board 100 is parallel to the end cap 700, a water flow rate test is required, and it is advantageous to fix the main floating board 100 to the end cap 700. The specific connection between the main floating board 100 and the end cap 700 can be various, such as a snap connection.

[0052] In one embodiment, the density of the end cap 700 is 0.5 to 0.8 times the density of water.

[0053] In this embodiment, the density of the end cap 700 is also limited so that the floating effect of the measuring device is appropriate and a better measuring effect can be provided. The material of the end cap 700 can be various types of plastics or foamed plastics.

[0054] Reference Figure 5 In one embodiment, the measuring device further comprises a telescopic rod 800, and the telescopic rod 800 is detachably connected to the mounting port.

[0055] In this embodiment, a telescopic rod 800 is directly adapted to the measuring device, and after the telescopic rod 800 is connected to the mounting port, the telescopic rod 800 can be used as a handheld base for the user. The telescopic form of the telescopic rod 800 can be various, based on the ability to achieve length adjustment, and can refer to various types of existing technologies, and the specific structure is not the focus.

[0056] In one embodiment, the plane bearing assembly 400 is detachably connected to the main floating board 100 .

[0057] In this embodiment, considering that the plane bearing assembly 400 is easily affected by the external environment, the plane bearing assembly 400 is set to a detachable structure, so that the plane bearing assembly 400 can be maintained and properly stored when not in use. The detachable setting method between the plane bearing assembly 400 and the main floating board 100 can be buckle connection, clamping connection and threaded connection, etc., which is not the focus here.

[0058] Reference Figures 1 to 4 In one embodiment, the plane bearing assembly 400 includes a plane bearing 410 and a mounting seat 420 for fixing the plane bearing 410 , and an internal threaded opening is provided on the main floating plate 100 , and the mounting seat 420 is threadedly connected with the internal threaded opening.

[0059] In this embodiment, a suitable structure of a plane bearing assembly 400 is provided to reduce the difficulty of processing and improve the convenience during use. The plane bearing 410 generally includes an inner ring and an outer ring, and a lubrication structure (such as a ball) is arranged between the inner ring and the outer ring. The connection position of the bearing cover 500 can be on the inner ring or the outer ring, wherein the outer ring is preferred. The mounting seat 420 fixes the plane bearing 410 on one hand, and serves as a basis for connecting the plane bearing 410 to the main floating board 100. For example, the mounting seat 420 is fixed to the inner ring of the plane bearing 410, and the bearing cover 500 is connected to the outer ring of the plane bearing 410. The outer wall of the free end of the mounting seat 420 is provided with an external thread, and the mounting seat 420 can be connected to the internal thread opening on the main floating board 100. During use, the plane bearing assembly 400 is screwed into the internal thread opening; and after use, the plane bearing assembly 400 is screwed out of the internal thread opening.

[0060] In one embodiment, the water flow velocity measuring unit 300 is of propeller type or ultrasonic type.

[0061] In this embodiment, two common water flow test types are given. The propeller type velocity measurement has the advantages of simplicity, low cost and easy maintenance; the ultrasonic type velocity measurement is not easily damaged by abnormal interference from impurities in the water body.

[0062] Reference Figure 1 Corresponding to the sleeve 600, a plurality of sealing sleeves 900 having the same size as each other are provided.

[0063] In this embodiment, when the measuring device is not equipped with a hand-held rod of a corresponding structure, the sleeve 600 can form a suitable connection with the rod-shaped structure of self-selected materials through the appropriate selection of the sealing tube 900. For example, after the rod-shaped structure is inserted into the sleeve 600, it is fixed by a clamp. At this time, when the sealing tube 900 is set between the rod-shaped structure and the inner wall of the sleeve 600, the number of sealing tubes 900 can form a size adaptation. The material of the sealing tube 900 can be various types of rubber, which is not the focus here.

[0064] In one embodiment, a safety rope is connected to the main floating board 100 .

[0065] In this embodiment, the safety rope greatly reduces the risk of accidental loss of the entire measuring device during the test; at the same time, when the water flow velocity measuring unit 300 is wired data transmission, the safety rope can reduce the tension on the data line. The main floating board 100 and the safety rope can be connected in various ways, which are not limited to the specific method. For example, a hanging ring is set on the main floating board 100, and the safety rope is connected to the hanging ring.
