Abstract
Description
Technical Field
[0001] The present application relates to the field of irrigation area flow monitoring equipment, and in particular to an irrigation area open channel metering equipment. Background Art
[0002] Water measurement in irrigation areas is a powerful measure to save irrigation water, improve irrigation quality and efficiency, and is an important means to implement planned water use and accurate water diversion, transmission and distribution. In order to accurately control water use in irrigation areas, it is necessary to monitor the water volume in the channel.
[0003] Among the current irrigation area water measurement equipment, the commonly used ones are contact measurement equipment and non-contact measurement equipment. Ultrasonic pipeline flowmeters, open channel ultrasonic flowmeters, open channel electromagnetic flowmeters, etc. are all contact measurement equipment. Long-term measurement in the channel water body is prone to silt accumulation and is easily blocked by garbage and debris in the channel, resulting in measurement failure and inaccuracy, and requires regular cleaning and maintenance. Therefore, non-contact measurement equipment is more suitable for installation and use in irrigation areas.
[0004] However, the measurement accuracy of non-contact measurement equipment is related to its relative height from the water surface. The higher the installation height, the weaker the echo and the worse the signal. On the contrary, if it is installed too low, the water surface will interfere more with the radar. Utility Model Content
[0005] In order to achieve accurate flow monitoring, the present application provides an irrigation area open channel metering device.
[0006] The open channel metering equipment for irrigation area provided in this application adopts the following technical solution:
[0007] An irrigation area open channel metering device comprises a base and a shell fixedly connected to the upper surface of the base, the upper surface of the base is rotatably connected to a first screw, the first screw is penetrated through the upper surface of the shell, the upper surface of the shell is fixedly connected to a first motor for driving the first screw to rotate, the first screw is threadedly connected to a lifting seat, the side wall of the lifting seat is connected to a sliding assembly, and a radar flow meter for monitoring channel flow is arranged below the sliding assembly.
[0008] By adopting the above technical solution, the first motor rotates to drive the first screw to rotate, and the rotation of the screw drives the lifting seat to rise and fall, thereby realizing the height adjustment of the radar flowmeter, preventing the radar flowmeter echo from weakening due to excessive installation height and affecting the measurement accuracy, thereby ensuring the accuracy of the measurement.
[0009] Optionally, a first guide column is passed through and slidably connected to the lifting seat, one end of the first guide column is fixedly connected to the upper surface of the base, and the other end is fixedly connected to the inner top wall of the shell.
[0010] By adopting the above technical solution, during lifting, the guide column can limit the running track of the lifting seat and prevent the lifting seat from rotating around the first screw rod, so that the lifting seat can only move in the vertical direction, thereby ensuring stability during lifting.
[0011] Optionally, the sliding assembly includes a second motor fixedly connected to the side wall of the lifting seat, a second screw fixedly connected to the output shaft of the second motor, and a sliding seat threadedly connected to the second screw, the second screw passes through the sliding seat, and the radar flowmeter is fixedly connected to the bottom of the sliding seat.
[0012] By adopting the above technical solution, the second motor drives the second screw to rotate, thereby driving the sliding seat to move in the horizontal direction, so that the equipment can adjust the monitoring position of the radar flowmeter according to the width of the channel, thereby ensuring that the radar flowmeter can be located in the middle of the channel, thereby improving the measurement accuracy.
[0013] Optionally, a rain shield is connected to the bottom of the sliding seat, and the rain shield is perpendicular to the side wall of the sliding seat.
[0014] By adopting the above technical solution, the rain shield can effectively prevent rain from directly wetting the radar flow meter, reduce the erosion of rain on the equipment, and extend the service life of the equipment; rain may interfere with the propagation of radar waves and affect the measurement accuracy. The rain shield can reduce this interference and ensure the accuracy of the measurement data.
[0015] Optionally, the sliding seat is provided with a through hole for a fastener to be embedded and threadedly connected, and the fastener is used to fix the radar flowmeter.
[0016] By adopting the above technical solution, the radar flow meter is easy to disassemble and install through the connection of fasteners, and is convenient for replacement during subsequent maintenance.
[0017] Optionally, a second guide column is connected to the side wall of the lifting seat, and the second guide column is penetrated by the sliding seat and is slidably connected to the sliding seat.
[0018] By adopting the above technical solution, the second guide column prevents the sliding seat from rotating around the second screw rod, thereby ensuring that the sliding seat can only be displaced along the length direction of the second screw rod, thereby improving stability during operation.
[0019] Optionally, the second guide column and the end of the second screw rod away from the lifting seat are located in the same plane, and the ends of the second guide column and the second screw rod are both connected to a limiting plate.
[0020] By adopting the above technical solution, when the sliding seat runs to the end of the second screw, it will abut against the limit plate to prevent the sliding seat from falling off the screw during operation, thereby ensuring the stability of the product operation process.
[0021] Optionally, a photovoltaic panel is provided on the side wall of the shell, and an angle formed by the photovoltaic panel and the upper surface of the base is 30° to 50°.
[0022] By adopting the above technical solution, it is more troublesome to connect power lines to most areas in the farmland irrigation area. Using traditional power grids for power supply requires laying long cables, which is costly. Photovoltaic panels can generate electricity on site, eliminating the trouble and cost of laying cables. The arrangement at an angle of 30 to 50 degrees is more conducive to photovoltaic panels converting solar energy into electrical energy.
[0023] In summary, this application has the following beneficial effects:
[0024] 1. By setting the first screw and the lifting seat, the height of the radar flowmeter can be adjusted according to the water level, thereby ensuring the signal strength of the echo and improving the accuracy of the measurement.
[0025] 2. By setting up the sliding component, the radar flow meter can be displaced in the horizontal direction, so that the equipment can adjust the monitoring position of the radar flow meter according to the width of the channel so that it is always located in the middle of the channel, thereby ensuring the accuracy of the measurement.

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The present application embodiment discloses an irrigation open channel metering device. Figure 1 , Figure 2The irrigation area open channel metering equipment includes a base 1 and a shell 2 fixedly connected to the upper surface of the base 1, a first screw 3 is arranged inside the shell 2, a first motor 4 for driving the first screw 3 to rotate is fixedly connected to the upper surface of the shell 2, one end of the first screw 3 is rotatably connected to the base 1, and the other end is fixedly connected to the output shaft of the first motor 4, the first screw 3 is threadedly connected to a lifting seat 5, a sliding assembly 6 is connected to the side wall of the lifting seat 5, and a radar flowmeter 7 is arranged below the sliding assembly 6. When in use, the first motor 4 is started, and the output shaft of the first motor 4 rotates to drive the first screw 3 to rotate. Since the lifting seat 5 is threadedly connected to the first screw 3, adjusting the rotation direction of the first screw 3 can realize the lifting of the lifting seat 5 and thus realize the height adjustment of the radar flowmeter 7.
[0032] Reference Figure 1 , Figure 2 A first guide column 51 penetrating the lifting seat 5 is disposed on the upper side of the base 1, one end of the first guide column 51 is fixedly connected to the base 1, and the other end is fixedly connected to the top wall of the shell 2. The first guide column 51 plays a role in positioning and guiding. During the lifting process, the lifting seat 5 will not rotate around the first screw rod 3 due to the influence of the first guide column 51, thereby ensuring the stability of the operation process.
[0033] Reference Figure 1 , Figure 2 The sliding assembly 6 includes a second screw 62, a second motor 61 for driving the second screw 62 to rotate, and a sliding seat 63 threadedly connected to the second screw 62. The body of the second motor 61 is fixedly connected to the side wall of the lifting seat 5, the output shaft of the second motor 61 is fixedly connected to one end of the second screw 62, and the second screw 62 is inserted into the sliding seat 63. When the sliding assembly 6 is in operation, the second motor 61 is started to drive the second screw 62 to rotate, and the sliding seat 63 moves along the length direction of the second screw 62. The equipment can adjust the monitoring position of the radar flowmeter 7 according to the width of the channel, so that the radar flowmeter 7 is always located in the middle of the channel, thereby adapting to channels of different widths and ensuring the flexibility and accuracy of measurement.
[0034] Reference Figure 1 , Figure 2 The side wall of the lifting seat 5 is fixedly connected with a second guide column 64 that penetrates the sliding seat 63, and the second guide column 64 and the end of the second screw 62 are fixedly connected with a limit plate 65. When the sliding seat 63 moves to the end of the second screw 62, the side wall of the sliding seat 63 will abut against the limit plate 65 to prevent it from moving further, preventing the sliding seat 63 from falling off the screw during operation, thereby ensuring the stability of the product operation process.
[0035] Reference Figure 2 , Figure 3In order to reduce the interference of rainwater on the radar flowmeter 7, a rain shield 631 is fixedly connected to the side wall of the sliding seat 63, and the rain shield 631 is perpendicular to the side wall of the sliding seat 63. On rainy days, raindrops may be mistaken by the radar as a moving target, resulting in false triggering. Therefore, the rain shield 631 is set at the front panel of the radar flowmeter 7 to improve the measurement accuracy. The rain shield 631 is perpendicular to the side wall of the sliding seat 63, so that while blocking raindrops, it will not block the front panel of the radar flowmeter 7 and will not interfere with the radar signal.
[0036] Reference Figure 2 , Figure 3 Through holes 632 are provided on both sides of the radar flow meter 7 and the bottom wall of the sliding seat 63, and the through holes 632 are used for threaded connection of fasteners. The radar flow meter 7 is fixed to the bottom of the sliding seat 63 by fasteners, and the radar flow meter 7 can be moved to the shore by cooperating with the lifting seat 5 and the sliding assembly 6, so as to facilitate disassembly and maintenance.
[0037] Reference Figure 1 In order to save the cost of laying cables in the irrigation area, a photovoltaic panel 8 is provided on the side wall of the housing 2. The photovoltaic panel 8 is provided at the top of the side wall of the housing 2, and the photovoltaic panel 8 forms an angle of 30 to 50 degrees with the upper surface of the base 1. It is troublesome to connect wires for power supply in the irrigation area. The photovoltaic panel 8 can generate electricity on site without using traditional power grids, saving costs. The arrangement at an angle of 30 to 50 degrees is more conducive to the photovoltaic panel 8 converting solar energy into electrical energy.
[0038] The implementation principle of an open channel metering device for an irrigation area in an embodiment of the present application is as follows: when the water level in the channel changes, the first motor 4 is started to drive the lifting seat 5 to move. At this time, the monitoring height of the radar flow meter 7 can be adjusted according to the water level to ensure the measurement accuracy of the radar flow meter 7.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
