Description

Technical Field

[0001] This utility model belongs to the field of channel flow measurement technology, and in particular relates to a channel flow measurement vehicle. Background Technology

[0002] Accurate flow measurement in water conservancy projects has long been a technical bottleneck, particularly in concealed engineering scenarios such as buried sewage treatment plants and underground pipe networks. Currently, traditional channel flow measurement suffers from the following systemic defects:

[0003] The measurement range of fixed measuring devices is limited;

[0004] Traditional portable flow meters require pre-entry of channel dimensions, while manual measurement of channel dimensions poses safety risks and is inefficient;

[0005] In flow measurement equipment equipped with a common mobile platform, the mobile platform requires a large turning space to turn, making it difficult to adapt to narrow T-shaped or L-shaped channels. For wider channels, it can only complete channel-side operations and cannot complete multi-point flow velocity measurement in the channel, resulting in limited accuracy of flow data.

[0006] The coordination of split-type measuring devices is insufficient, and there is a problem of temporal and spatial asynchrony between the flow velocity and cross-sectional measurements of existing flow meters. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this utility model provides a channel flow measurement vehicle that can accurately measure the flow rate of various channels.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A channel flow measurement vehicle includes a van body. Mecanum wheels driven by a rotary drive mechanism are provided at the four lower corners of the van body. An on-board power supply and an industrial control computer are provided inside the van body. A mounting bracket is slidably connected to the upper end of the van body along the longitudinal direction. A communication antenna, a navigation radar, and a first linear drive mechanism for driving the mounting bracket to slide along the longitudinal direction are fixedly connected to the upper end of the van body. A Doppler flow meter measuring probe is provided at one end of the mounting bracket. A second linear drive mechanism is fixedly connected to the other end of the mounting bracket along the vertical direction. The output end of the second linear drive mechanism extends downward and is fixedly connected to a sonar.

[0010] The rotary drive mechanism, vehicle power supply, communication antenna, navigation radar, first linear drive mechanism, Doppler flow meter measuring probe, second linear drive mechanism and sonar are all electrically connected to the industrial control computer, and the communication antenna is electrically connected to the terminal equipment.

[0011] Furthermore, a flow meter data module connected to the industrial control computer is installed inside the van.

[0012] Furthermore, the sides of the van body are detachably connected to inspection covers.

[0013] Furthermore, four rotating drive mechanisms are horizontally fixedly connected to the four corners of the lower end of the van body, and the output end of the rotating drive mechanism is coaxially fixedly connected to a Mecanum wheel.

[0014] Furthermore, the rotation drive mechanism is a servo motor.

[0015] Furthermore, two linear guide rails are longitudinally arranged at the upper end of the van body, and the two sides of the mounting bracket are respectively fixedly connected to the slider ends of the two linear guide rails.

[0016] Furthermore, the slide rail ends of the two linear guide rails are fixedly connected to the van body.

[0017] Furthermore, both the first linear drive mechanism and the second linear drive mechanism are linear motors.

[0018] Furthermore, the van body is equipped with a charging port for charging the vehicle's power supply.

[0019] Furthermore, a charging port is provided on the end of the van body away from the mounting bracket.

[0020] The beneficial effects of this utility model are as follows:

[0021] The channel flow measurement vehicle, equipped with four sets of Mecanum wheels, can turn and move within the narrow space of a channel to reach various locations for flow measurement. Combining Doppler flowmeters and sonar technology, it can simultaneously measure channel velocity and channel cross-sectional area for accurate flow measurement. When the channel flow measurement vehicle is placed laterally, the Doppler flowmeter probe and sonar can move laterally with the mounting frame to perform multi-point velocity measurements on the channel cross-section, thereby improving the accuracy of the flow measurement values.

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] This utility model provides a channel flow measurement vehicle, such as Figure 1-3 and Figure 5 As shown, the vehicle includes a van body 8. Mecanum wheels 9 driven by a rotating drive mechanism 16 are provided at the four corners of the lower end of the van body 8. The van body 8 is equipped with an on-board power supply 11, an industrial control computer 12, and a flow meter data module 13 for receiving and analyzing various data. A mounting bracket 3 is slidably connected to the upper end of the van body 8 along the longitudinal direction. A communication antenna 6 for receiving or outputting data, a navigation radar 7 for automatic navigation and positioning, and a first linear drive mechanism 4 for driving the mounting bracket 3 to slide along the longitudinal direction are fixedly connected to the upper end of the van body 8. A Doppler flow meter measuring probe 1 is provided at one end of the mounting bracket 3. A second linear drive mechanism 2 is fixedly connected to one end of the mounting bracket 3 along the vertical direction. The output end of the second linear drive mechanism 2 extends downward and is fixedly connected to a sonar 10.

[0033] The rotary drive mechanism 16, vehicle power supply 11, flow meter data module 13, communication antenna 6, navigation radar 7, first linear drive mechanism 4, Doppler flow meter measuring probe 1, second linear drive mechanism 2 and sonar 10 are all electrically connected to the industrial control computer 12, and the communication antenna 6 is electrically connected to the terminal equipment.

[0034] Understandably, the channel flow measurement vehicle, with the aid of four sets of Mecanum wheels 9, can achieve more flexible turning, allowing it to turn and move within the narrow space of a channel, enabling it to move to any position in the channel for flow measurement. Combined with Doppler flow meter and sonar 10 technology, it can simultaneously measure channel velocity and channel cross-sectional area for accurate channel flow measurement. When the channel flow measurement vehicle is placed laterally, the Doppler flow meter probe 1 and sonar 10 can move laterally with the mounting frame 3 to measure the flow velocity at multiple points on the channel cross-section, thereby obtaining the channel cross-sectional flow curve distribution and achieving accurate channel flow measurement.

[0035] It should be noted that the communication antenna 6 and navigation radar 7 can realize the automatic positioning and navigation of the channel flow measurement vehicle, so as to realize accurate channel measurement remotely; the industrial control computer 12 integrates the Doppler flow meter and sonar 10 and other equipment to transmit data, and after analysis and processing, the results are output to terminal devices such as computers or mobile phones through the communication antenna 6.

[0036] It should also be noted that the channel flow measurement vehicle generally moves longitudinally. At this time, the Doppler flow meter measuring probe 1 and the sonar 10 can move longitudinally with the mounting frame 3. When performing multi-point flow velocity measurement on the channel cross-section, the channel flow measurement vehicle is placed laterally. Accordingly, the Doppler flow meter measuring probe 1 and the sonar 10 can move laterally with the mounting frame 3.

[0037] In one embodiment, such as Figure 4 As shown, a maintenance cover 15 is detachably connected to the side of the van body 8 so that the maintenance cover 15 can be opened to inspect the components inside the van body 8.

[0038] In one embodiment, four rotating drive mechanisms 16 are horizontally fixedly connected to the four corners of the lower end of the van body 8, and the output end of the rotating drive mechanism 16 is coaxially fixedly connected to the Mecanum wheel 9; wherein, the rotating drive mechanism 16 is a servo motor.

[0039] In one embodiment, the upper end of the van body 8 is provided with two linear guide rails 5 along the longitudinal direction, and the two sides of the mounting bracket 3 are respectively fixedly connected to the slider ends of the two linear guide rails 5.

[0040] Specifically, the slide rail ends of the two linear guide rails 5 are fixedly connected to the van body 8.

[0041] In one embodiment, both the first linear drive mechanism 4 and the second linear drive mechanism 2 are linear motors.

[0042] In one embodiment, such as Figure 1 and Figure 4 As shown, the van body 8 is provided with a charging port 14 for charging the vehicle power supply 11, and the charging port 14 is located at the end of the van body 8 away from the mounting bracket 3.

[0043] In summary, this utility model has an integrated van body 8, which integrates the vehicle power supply 11, industrial control computer 12, communication antenna 6, navigation radar 7, first linear drive mechanism 4, Doppler flow meter, second linear drive mechanism 2, sonar 10, flow meter data module 13 and linear guide rail 5 into one complete set of equipment.

[0044] This utility model can improve the efficiency and safety of measurement in narrow spaces. In scenarios where traditional equipment is inconvenient, such as underground sewage treatment plant culverts, it can realize automatic measurement of channel flow, significantly improving the efficiency of a single operation compared to manual work, and avoiding the risk of personnel entering toxic or oxygen-deficient environments.

[0045] This invention can improve the accuracy of flow measurement by using spatial synchronous measurement between sonar 10 and Doppler flow meter to eliminate the reference plane offset error of traditional split-type equipment.

[0046] This invention can adapt to more narrow spaces. It is equipped with Mecanum wheels 9, which can make more flexible turns, enabling the channel flow measurement vehicle to turn in narrow spaces.
