A water level detection system based on Beidou satellite positioning and its application

Abstract

The invention discloses a water level detection system based on Beidou satellite positioning and an application thereof, and specifically relates to the technical field of water conservancy detection. The invention detects wind direction and wind speed through a wind direction sensor, and controls a rotating mechanism to slide in a spiral groove according to different wind direction positions, so that a support column can drive a protective structure to rotate, so that the protective structure adjusts the right protrusion surface to be opposite to the flow direction of strong winds. Since both sides of the front protrusion in the middle of the protective structure are inclined surfaces, the protective structure can cut the airflow when the airflow passes through, so that the airflow can be dispersed and guided along the inclined surface of the protective structure, thereby reducing the contact area between the entire device and the airflow, and reducing the force of the airflow, so that the device is not easily broken by strong winds to affect the use and increase the subsequent maintenance cost. At the same time, the device controls the radar water level gauge to leave the water surface through rotation, thereby facilitating the inspection and maintenance of the radar water level gauge.

[0002] In water conservancy project construction, it is usually necessary to detect the water level to facilitate recording the rise and fall of the water level. The commonly used water level detection equipment is generally a water level tester, which consists of a fixed bracket, a distribution box and a radar water level meter.

[0003] Existing water level testers are generally fixed structures, which greatly reduce the life of distribution boxes and radar water level gauges in an environment exposed to the sun and rain, and the detection port surface of the radar water level gauge is easily contaminated with dust, which is not easy to clean. Moreover, the radar water level gauge is generally extended to the upper part of the water surface through a bracket. Not only can it not measure the water levels of multiple rivers or the water levels of multiple locations in the same river, but it is also inconvenient to inspect and disassemble. In addition, general water level testers are set up on the open riverside. When encountering strong winds, the fixed brackets are easily broken by the strong winds, affecting subsequent use. In addition, the power supply of the sensors in the water level monitoring area and its communication system are all powered by solar panels. However, in order to maintain the power supply efficiency, this design requires regular and dynamic adjustment of the solar angle of the photovoltaic panel, and the above-mentioned windproof storage mechanism and the solar angle adjustment mechanism of the photovoltaic panel require multiple driving mechanisms to drive the operation, so its overall size is large and the reliability is low, and the cost is expensive.

An electromagnet module is arranged in the reinforcing rib net, and the electromagnet module matches the minimum height of the pin. A transverse through hole is arranged in the cylindrical block, and the pin passes through the transverse through hole. A reset spring is embedded in the transverse through hole, and both ends of the reset spring are respectively fixed to the pin body and the inner wall of the transverse through hole.

[0009] As a further solution of the present invention: an alarm is installed on the front side above the support column, the storage structure includes a mounting seat, the mounting seat is embedded and installed in the middle of the support column, a concave plate is fixedly connected to the left side of the mounting seat, the position of the concave plate corresponds to the position of the baffle, a sponge layer is fixedly connected inside the concave plate, and a control cabinet is fixedly connected to the front side of the concave plate.

[0011] As a further solution of the present invention: a fixing rod is fixedly connected to the right side of the motor, the bottom end of the fixing rod is fixedly connected to the top of the fixing frame, the upper and lower sides of the inner wall of the fixing frame are respectively fixedly connected to the upper and lower ends of the guide rod, and the threaded seat is slidably connected to the outside of the guide rod.

[0014] An application of a water level detection system based on Beidou satellite positioning includes the following steps:

[0015] S1. First, control the motor to drive the screw to rotate, so that the screw drives the telescopic frame to unfold through the screw, so that the telescopic frame unfolds the fixed frame, so that the fixed frame can drive the bottom radar water level meter to adjust the position, so that the radar water level meter cooperates with the Beidou positioning module to realize the detection of different water levels.

[0016] S2. When encountering strong winds, the wind direction sensor monitors the wind direction and wind speed, and transmits the signal to the alarm to warn people nearby. At the same time, the wind direction sensor controls the operation of the motor and the electric push rod in turn through the adjustment control module, so that the motor reverses and drives the threaded seat to move through the screw, so that the telescopic frame contracts, and the fixed frame drives the radar water level meter to fold, so that the baffle and the concave plate are closed, and the radar water level meter is wiped and cleaned through the sponge layer. At the same time, the baffle and the concave plate protect the radar water level meter.

[0017] S3, then control the electric push rod to drive the roller to move through the cylindrical block, so that the roller slides in the spiral groove, so that the roller squeezes the spiral groove when sliding and drives the support column to rotate, so that the support column drives the guard plate to rotate through the plug plate, so that the direction of the guard plate is opposite to the wind direction, so that when the airflow passes through the guard plate, the guard plate cuts and disperses the airflow and guides it from both sides due to the protrusion of the middle part of the guard plate, thereby protecting the device as a whole. During the above process, the electromagnet module is closed, so that the roller of the latch is tightly attached to the spiral groove under the action of the reset spring;

[0018] S4. If the pitch angle of the solar panel to the sun needs to be adjusted, the electromagnetic module is controlled to open so that the roller at one end of the pin is disengaged from the spiral groove and the magnetic block at the other end of the pin is attracted by the electromagnetic module and inserted into the grid of the reinforcing rib net. At this time, the electric push rod is controlled to rise, which can drive the reinforcing rib net to rise so that the top of the reinforcing rib net abuts against one end of the solar panel to drive the solar panel to adjust the pitch angle. When it is necessary to store the solar panel, the electric push rod is first controlled to descend to the lowest point and the electromagnetic module is closed. At this time, the pin is reset under the action of the reset spring and drives the roller to enter the spiral groove again, and step S4 is performed again according to the pitch angle adjustment.

[0019] The beneficial effects of the present invention are:

[0020] 1. In the present invention, the same electric push rod is used in conjunction with the relatively slidable design inside the protective plate body, as well as the coordination of the electromagnet module, the return spring, and the transverse through hole, so that the wind shelter angle rotation and the solar panel pitch angle adjustment can be switched according to different needs. In addition, the inner and outer double layers of the protective structure are vertically relatively slidable, so that while strengthening the wind resistance, it can also reduce the lifting weight in adjusting the photovoltaic panel to the sun, save the power consumption of the electric push rod, and enhance the endurance.

[0021] 2. The present invention detects wind direction and wind speed through a wind direction sensor, and controls the rotating mechanism to slide in the spiral groove according to different wind direction positions, so that the support column can drive the protective structure to rotate, so that the protective structure adjusts the right protrusion to be opposite to the direction of strong wind flow. Since the two sides of the front protrusion in the middle of the protective structure are inclined, the protective structure can cut the airflow when the airflow passes through, so that the airflow can be dispersed and guided along the inclined surface of the protective structure, thereby reducing the contact area between the device as a whole and the airflow, and reducing the force of the airflow, so that the device is not easily broken by strong winds, affecting the use and increasing the subsequent maintenance cost. At the same time, the device controls the radar water level gauge to leave the water surface through rotation, thereby facilitating the inspection and maintenance of the radar water level gauge;

[0022] 3. The present invention drives the threaded seat to move by a motor-driven screw, so that the threaded seat can control the expansion movement of the telescopic frame, and the telescopic frame controls the radar water level meter to adjust the position. Therefore, the device can use an active adjustment method to measure the water levels at different positions or the water levels of multiple rivers, so that the detection accuracy is higher and the water level detection range is improved. At the same time, the baffle plate and the concave plate are closed by the contraction of the telescopic frame, so that the radar water level meter can be wiped and cleaned through the sponge layer. At the same time, the concave plate and the baffle plate can cooperate to achieve closed protection for the radar water level meter to avoid damage to the radar water level meter in severe weather.

In the above process, the electromagnet module is closed, so that the roller 34 of the latch is tightly attached to the spiral groove 12 under the action of the reset spring;

[0042] S4. If the pitch angle of the solar panel 7 needs to be adjusted, the electromagnetic module is controlled to open so that the roller 34 at one end of the latch is disengaged from the spiral groove 12 and the magnetic block at the other end of the latch is attracted by the electromagnetic module and inserted into the grid of the reinforcing rib net 52. At this time, the electric push rod 32 is controlled to rise, which can drive the reinforcing rib net 52 to rise so that the top of the reinforcing rib net 52 abuts against one end of the solar panel 7 to drive the solar panel 7 to adjust the pitch angle.

4. The application of a water level detection system based on Beidou satellite positioning according to any one of claims 1 to 3, characterized in that: The following steps are involved: S1. First, the motor (66) is controlled to drive the screw rod (62) to rotate, so that the screw rod (62) drives the telescopic frame (68) to perform an unfolding operation through the screw rod (62), so that the telescopic frame (68) unfolds the fixed frame (61), so that the fixed frame (61) drives the bottom radar water level meter (610) to adjust its position, so that the radar water level meter (610) cooperates with the Beidou positioning module (69) to realize the detection operation of different water levels; S2. When encountering strong winds, the wind direction sensor (11) monitors the wind direction and wind speed, and transmits the signal to the alarm (10) to warn people nearby. At the same time, the wind direction sensor (11) controls the motor (66) and the electric push rod (32) in sequence through the adjustment control module, so that the motor (66) reverses and drives the threaded seat (63) to move through the screw rod (62), so that the telescopic frame (68) contracts, so that the fixed frame (61) drives the radar water level meter (610) to retract, so that the baffle (611) and the concave plate (82) are closed, so that the radar water level meter (610) is wiped and cleaned through the sponge layer (83), and the baffle (611) and the concave plate (82) protect the radar water level meter (610); S3, then controlling the electric push rod (32) to drive the roller (34) to move through the cylindrical block (33), so that the roller (34) slides in the spiral groove (12), so that the roller (34) squeezes the spiral groove (12) when sliding, driving the support column (2) to generate a rotational motion, so that the support column (2) drives the guard plate (51) to rotate through the plug plate (53), so that the direction of the guard plate (51) is opposite to the wind direction, so that when the airflow passes through the guard plate (51), due to the protrusion of the middle part of the guard plate (51), the guard plate (51) cuts and disperses the airflow and guides it from both sides, thereby protecting the device as a whole. During the above process, the electromagnet module is closed, so that the roller (34) of the latch is tightly attached to the spiral groove (12) under the action of the reset spring; S4. If the pitch angle of the solar panel (7) needs to be adjusted, the electromagnet module is controlled to be turned on so that the roller (34) at one end of the latch is disengaged from the spiral groove (12) and the magnetic block at the other end of the latch is attracted by the electromagnet module and inserted into the grid of the reinforcing rib net (52). At this time, the electric push rod (32) is controlled to rise, driving the reinforcing rib net (52) to rise so that the top of the reinforcing rib net (52) abuts against one end of the solar panel (7) and drives the solar panel (7) to adjust the pitch angle. When it is necessary to store the solar panel, the electric push rod (32) is first controlled to descend to the lowest point and the electromagnet module is turned off. At this time, the latch is reset under the action of the reset spring and drives the roller (34) to enter the spiral groove (12) again, and step S4 is performed again according to the pitch angle adjustment.
