The next level of farm channels is the small channels, which are used for irrigation or salt washing in each field.

[0003] Farmland channel flow measurement can provide irrigation data support for farmers more accurately and conveniently. Through farmland channel flow measurement, farmers can check irrigation conditions and water resource usage at any time, so as to better allocate water resources and improve agricultural production efficiency. At the same time, through the statistics and analysis of monitoring data, useful information about farmland irrigation conditions can be extracted to provide a scientific basis for agricultural water resources management. With the construction of high-standard farmland, agricultural water price reform and the requirements of the most stringent water resources management system, the measurement of farmland channel irrigation water has become more and more important.

[0004] Since the measuring device needs to be placed in the channel when measuring the channel flow, and since the water flow will impact the measuring device during the measurement, the measuring device needs to be fixed during use. However, in the prior art, the operation of fixing the measuring device is usually complicated. Therefore, we propose a new channel flow rate measuring device to solve the above-mentioned problems.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-Figure 6 The utility model provides a novel channel flow velocity measuring device, comprising a channel 1, a fixing component 2 arranged on the channel 1, a measuring component 3 arranged on the fixing component 2, and a limiting component 4 arranged between the channel 1 and the measuring component 3;

[0036] Among them, the fixing component 2 includes a fixing seat 21, a hollow roller 22, a clamping block 23 and an adjusting member 24. The fixing seat 21 is fixedly connected to the inner surface of the channel 1. A fixing groove is opened at the upper end of the fixing seat 21. The hollow roller 22 is fixedly connected in the fixing groove. The clamping block 23 is fixedly connected to the inside of the hollow roller 22. The adjusting member 24 is arranged inside the hollow roller 22. The adjusting member 24 includes a threaded portion 241 and an extrusion portion 242. The extrusion portion 242 is arranged as an internal hollow conical structure. The threaded portion 241 is threadedly connected to the hollow roller 22, and the extrusion portion 242 is sleeved on the upper end of the clamping block 23.

[0037] Specifically, when measuring the flow velocity of a farmland channel, the measuring component 3 can be first set in the channel 1. In order to ensure the stability of the measuring component 3 during the measurement and prevent the measuring component 3 from moving and rotating under the impact of the water flow, a fixing component 2 can be set in the channel 1, and the measuring component 3 can be set on the fixing component 2. The position of the measuring component 3 can be further fixed by the limiting component 4 to prevent the measuring component 3 from rotating.

[0038] Furthermore, when fixing the measuring component 3, the fixing seat 21 can be set inside the channel 1, and the hollow roller 22 can be fixedly connected inside the fixing groove, and the clamping block 23 can be fixedly connected inside the hollow roller 22, and the adjusting member 24 can be threadedly set inside the hollow roller 22. At this time, the measuring component 3 is inserted into the clamping block 23, and then the adjusting member 24 can be rotated to drive the adjusting member 24 to move up and down. When the adjusting member 24 descends, the upper end of the clamping block 23 can be squeezed inwardly by the squeezing portion 242, so that the clamping block 23 is deformed, and then the measuring component 3 inserted into the clamping block 23 can be squeezed, so that the measuring component 3 can be fixed, and when releasing the fixation, the adjusting member 24 can be rotated in the opposite direction, so that the squeezing portion 242 can release the squeezing of the upper end of the clamping block 23, and then the fixing of the measuring component 3 can be released.

[0039] In this embodiment, the measuring assembly 3 includes a measuring device 31 and an insertion rod 32. The insertion rod 32 is fixedly connected to the lower end of the measuring device 31. The insertion rod 32 passes through the hollow roller 22, the clamping block 23 and the adjusting member 24 and extends out of the surface of the hollow roller 22.

[0040] Specifically, in order to enable the measuring device 31 to be better fixed, an insertion rod 32 is fixedly set at the lower end of the measuring device 31. When in use, the insertion rod 32 is inserted into the hollow roller 22, the clamping block 23 and the adjusting member 24, and then the adjusting member 24 can be rotated to squeeze and fix the insertion rod 32, so that the measuring device 31 can be stably set in the channel 1.

[0041] In this embodiment, the measuring component 3 also includes a fixed block 33, which is fixedly connected to the upper end of the measuring device 31, and a threaded hole is provided on the surface of the fixed block 33; the limiting component 4 includes a connecting seat 41 and a limiting arm 42, the connecting seat 41 is fixedly connected to the inner surface of the channel 1, and the limiting arm 42 is rotatably connected to the connecting seat 41; the limiting arm 42 can be arranged on the fixed block 33, and an insertion hole is provided on the surface of the limiting arm 42, and the center of the insertion hole and the threaded hole are arranged on the same straight line.

[0042] Specifically, during use, in order to prevent the measuring device 31 from rotating under the impact of water flow, a connecting seat 41 can be set in the channel 1, and a limiting arm 42 can be rotatably set on the connecting seat 41 to connect the limiting arm 42 and the fixed block 33. Since the fixed block 33 is fixedly connected to the upper end of the measuring device 31, the limiting arm 42 can be used to limit the fixed block 33, thereby preventing the measuring device 31 from rotating.

[0043] In this embodiment, the limiting assembly 4 further includes a limiting rod 43 , which is threadedly disposed in the threaded hole, and the limiting rod 43 passes through the limiting arm 42 and extends out of the surface of the limiting arm 42 .

[0044] Specifically, in order to enable the limiting arm 42 to be stably connected to the fixed block 33, a threaded hole can be opened on the fixed block 33, an insertion hole can be opened on the limiting arm 42, and the limiting rod 43 can be set inside the two, so that the limiting arm 42 and the fixed block 33 can be stably set.

[0045] In this embodiment, the measuring device 31 is configured as a rectangular structure.

[0046] Specifically, the measuring device 31 is a rectangular device that can measure the water surface depth on both the front and back sides. The rectangular measuring device 31 is more likely to form stagnant water when encountering water with a high flow rate, thereby facilitating subsequent measurements.

[0047] In this embodiment, the depth of the water-facing surface after water accumulation is H1, the depth of the water-receiving surface is H2, and the difference between H1 and H2 is △Z, that is, H1-H2=△Z;

[0048] According to the formula △Z=η(V2-V02)

[0049] Where:

[0050] △Z: waterlogging height (m)

[0051] η: Waterlogging coefficient, related to water flow resistance, generally taken as 0.05 for channels

[0052] V: Average flow velocity of the section after construction (m / s)

[0053] V0: Average flow velocity of the section before construction (m / s).

[0054] Specifically, by measuring the depth H1 of the upstream surface after water accumulation and the depth H2 of the downstream surface, we can directly read the difference △Z of H1-H2, and H1-H2=△Z. Then, through the above formula, we can get that △Z has a linear relationship with the flow velocity V0, because the flow velocity V0 can be obtained by reading different △Z.

[0055] The working principle and use process of the utility model are as follows: when measuring the flow rate of water in a farmland channel, the fixing component 2 can be first fixed in the channel 1, and then the measuring component 3 can be inserted into the fixing component 2, and the measuring device 31 can be squeezed and clamped by rotating the adjusting member 24, so that the measuring component 3 can be relatively stably arranged in the fixing component 2, and during the flow rate measurement, the position of the measuring device 31 will not be changed when the water flow impacts the measuring device 31, and during use, in order to prevent the measuring device 31 from rotating, a limit component 4 can be set in the channel 1, and the measuring component 3 and the limit component 4 are connected, so that the measuring device 31 can maintain its angle and position unchanged.

[0056] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.

[0057] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
