Description

Technical Field

[0001] The utility model relates to the technical field of large-span river and sensitive water body monitoring, in particular to an orbital channel automatic flow measurement vehicle with a lightweight structure. Background Technique

[0002] Due to the fluidity of rivers, the scope of pollution impact is not limited to the pollution occurrence area. Pollution in the upper reaches will quickly affect the lower reaches. Even pollution in a section of the river can affect the ecological environment of the entire river channel (considering fish migration, etc.). River water is the main drinking water source. Pollutants can directly poison the human body through drinking water, or indirectly endanger human health through the food chain and irrigated farmland.

[0003] The pollution degree varies with the runoff. Under the same sewage discharge, the larger the river runoff, the lower the pollution degree; the seasonal change of runoff brings differences in pollution degree over time. In addition, in irrigation areas and water body sensitive areas, the daily regular monitoring of suspended solids such as sediment in the water body and additional measurements in case of emergencies are also the key points of monitoring. At present, water sample collection and in-water flow measurement mostly adopt manual methods or other semi-automatic means. Building a measurement bridge with a rigid track as the carrier and using an automatic flow measurement vehicle to replace manual work also has certain applications, but there are mostly some small cross-sections with short spans and many limitations. Therefore, the research and development of automatic flow measurement equipment for large-span channels is still one of the pain points in the industry.

[0004] Limited by the difficulty of flow measurement technology in realizing large-span channel measurement, currently, for the monitoring of polluted rivers, the flow measurement location is still set above a relatively narrow river channel near the pollution source. For areas with large channel spans, it is still a measurement blind spot, and only local measurements can be carried out by setting water quality monitoring equipment along the channel edge. Due to the lack of support from accurate flow data, the polluted data collected at present is difficult to comprehensively reflect the river pollution status. Summary of the Invention

Detailed implementation mode

[0042] The following further describes the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0043] The present utility model discloses an orbital channel automatic flow measurement vehicle with a lightweight structure. The orbital channel automatic flow measurement vehicle is installed on a rigid track and moves along the rigid track; the rigid track includes several square steel pipes welded together and is erected above the cross-section of the river channel in the form of a simply supported beam; the length of the cross-section of the river channel is not less than 50 meters;

[0044] The orbital channel automatic flow measurement vehicle includes a vehicle body, a wheel assembly, a driving motor, a lifting motor, a flow measurement assembly, a water sample collection device, a rain gauge, a first communication component, and a second communication component;

[0045] The wheel assembly includes two driving wheels and two driven wheels. The circumferences of the driving wheels and the driven wheels are wrapped with a polyurethane wrapping layer of a certain thickness. The surface width of the polyurethane wrapping layer is greater than the width of the square steel, and it contacts the upper plane of the square steel track, with large friction, good wear resistance and physical properties, smooth movement, low noise and vibration. Guide slides are installed inside the driving wheels and the driven wheels.

The two driving wheels are connected to the driving motor and, under the action of the driving motor, move the vehicle body on the rigid track together with the driven wheels;

[0046] Both the flow measurement assembly and the water sample collection device are connected to the lifting motor.

[0050] The guiding slide plate is made of polytetrafluoroethylene, and the side area of the guiding slide plate is larger than the side area of the wheel body.

[0051] The flow measurement assembly includes a counting wheel, a limiter, a river bottom signal generator, a lead fish and a current meter; the counting wheel and the limiter are installed on the cross beam above the front part of the vehicle body. One end of the steel wire rope is fixed on the lifting component and tightly wound. After passing around the counting wheel, the other end is connected to the lead fish through the river bottom signal generator. The flow measurement vehicle of the present utility model can be adapted to the conventional flow measurement assemblies on the market, and the flow measurement principle is the same as that of the prior art. That is, the flow measurement vehicle is moved to a certain location, and the lifting component is used to release the lead fish and the river bottom signal generator. After touching the bottom, the current meter is used to measure the flow velocity of the area where it is located.

[0052] The water sample collection device can be attached to the side of the lead fish or installed on the steel wire rope to collect sediment suspended load samples while measuring the flow. The collected sediment suspended load samples are carried back to the river bank by the flow measurement vehicle and detected by the staff or the detection equipment set on the river bank.

[0053] The flow velocity of large cross-section rivers is relatively fast, so the lead fish usually used is also relatively heavy. The present utility model optimizes the frame structure of the flow measurement vehicle so that the flow measurement vehicle can carry a lead fish weighing more than 100 Kg. Specifically, such as Figure 1As shown in the figure, the vehicle body includes a frame component and a body shell component; the frame component includes a first longitudinal support, a second longitudinal support, a first longitudinal load beam, a second longitudinal load beam, a first transverse support, a second transverse support, a load cross beam, two driving wheel supports, a drive motor support, a lifting motor support, and two driven wheel supports; the first longitudinal support and the second longitudinal support are parallel to each other, the first transverse support and the second transverse support are parallel to each other, the first transverse support is vertically connected to one of the tops of the first longitudinal support and the second longitudinal support, and the second transverse support is vertically connected to the middle regions of the first longitudinal support and the second longitudinal support; the first longitudinal support, the second longitudinal support, the first transverse support, and the second transverse support intersect to form a frame platform; the two driving wheel supports are respectively installed at the angles between the first longitudinal support and the first transverse support, and between the first longitudinal support and the second transverse support, for carrying two driving wheels; the two driven wheel supports are arranged oppositely and are respectively installed at the tail regions of the first longitudinal support and the second longitudinal support far from the load cross beam, for carrying two driven wheels; the first longitudinal load beam and the second longitudinal load beam are both vertically welded to the middle regions of the first transverse support and the second transverse support, for carrying the flow measurement component and the power supply unit; the load cross beam is vertically welded to the middle regions of the first longitudinal support and the second longitudinal support, for carrying the flow measurement component; the drive motor support is located below the frame platform and directly below one of the driving wheels, and the drive motor is installed in the drive motor support; the lifting motor support is installed above the frame platform, and the lifting motor is installed in the lifting motor support. A column support is vertically arranged above the frame platform, and a reinforcing brace is connected between the column support and the frame platform. The longitudinal support and the transverse support form a frame platform. After being reinforced by the driving wheel support and the driven wheel support, the corresponding wheel assemblies are carried. The longitudinal load beam is used to carry heavy electronic devices such as the measurement and control unit and the power supply unit through reliable welding. The drive motor support and the lifting motor support are reliably connected to the longitudinal load beam, independently carry the corresponding motor and reducer, and bear the torque generated by them. The load cross beam is fixed by the column support and strengthened by the reinforcing brace, and can withstand a lead fish load of more than 100 Kg.

[0054] As Figure 3 shown, in order to reduce the overall weight of the vehicle body, the present utility model has improved the body shell component. The body shell component is sleeved on the frame component and includes a body shell and reinforced aluminum plates. The reinforced aluminum plates are fixed on both sides of the body shell, maintaining the firmness of the vehicle body while reducing its weight. As Figure 2 shown, the body shell component includes a lower cover shell, a rear cover plate, an antenna, an upper cover plate, a front cover shell, and a handle; the lower cover shell is fixed to the frame platform by M6 bolts, the rear cover plate and the upper cover plate are fixed to the lower cover shell by snap pins, and are closed with a door lock; the antenna is installed at the rear of the frame and led out through the holes on the lower cover shell; the handles are respectively installed on both sides of the lower cover shell and above the side of the front cover shell.

[0055] There are two sets of communication components mounted on the flow measurement vehicle of the present utility model. The first communication component uses a LoRa communication module, which is mainly responsible for communicating with water quality monitoring devices at nearby monitoring points and collecting water quality parameters sent by the water quality monitoring devices. The second communication component uses a WiFi communication module, which is responsible for communicating with the remote control center and sending the collected water quality parameters, flow velocity data, and rainfall information to the remote control center.

[0056] As one of the preferred examples, limited by the limited communication distance of the LoRa communication module, for some areas, the flow measurement vehicle can also serve as a signal relay point to transmit the collected data of water quality monitoring devices deployed at nearby monitoring points to the remote control center over a long distance, lifting the restriction on the deployment locations of some water quality monitoring devices.

[0057] As one of the preferred examples, a water quality detector is mounted on the orbital channel automatic flow measurement vehicle, which can, under the control of the staff, measure the water quality at any point on the channel cross-section, for example, at the center of the river. On this basis, the staff no longer need to deploy water quality monitoring devices separately, reducing the water quality monitoring cost.

[0058] As one of the preferred examples, the orbital channel automatic flow measurement vehicle includes a flow measurement mode control circuit; the flow measurement mode control circuit is respectively connected to the first communication component and the rain gauge. When the water quality parameters received by the first communication component exceed the preset water quality parameter threshold, a first flow measurement mode signal is output; when the rain gauge feeds back rainfall, a second flow measurement mode signal is output; otherwise, a third flow measurement mode signal is output; the flow measurement frequencies corresponding to the first flow measurement mode signal, the second flow measurement mode signal, and the third flow measurement mode signal are different. For example, when the water quality parameters received by the first communication component exceed the preset water quality parameter threshold, a first flow measurement mode signal is output to measure the river flow velocity at the highest frequency; when the rain gauge feeds back rainfall, a second flow measurement mode signal is output to measure the river flow velocity at a medium frequency; otherwise, a third flow measurement mode signal is output to measure the river flow velocity at the lowest frequency. This part of the setting can reduce the number of control outputs of the remote control center and save the energy consumption of the automatic flow measurement vehicle.

[0059] As one of the preferred examples, a flow measurement house is arranged on one side of the rigid track, and a charging pile is arranged in the flow measurement house. Electrodes are installed on the vehicle body of the orbital channel automatic flow measurement vehicle at positions corresponding to the charging pile, so that the flow measurement vehicle can be charged by using the charging pile.

Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present application.

[0061] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application is also intended to include these changes and modifications.
