Description

Technical Field

[0001] The utility model relates to a detection device, in particular to an automatic lake silt measuring device. Background Art

[0002] Lakes are an important part of the ecosystem, and lake silt detection is of great significance for protecting the lake ecological environment. By removing pollutants and toxic substances in the silt, a better living environment can be provided for the organisms in the lake, promoting the restoration and stability of the lake ecosystem.

[0003] At present, when the lake silt detection device conducts mobile detection on the lake, its detection component needs to be exposed at the bottom of the device to conduct detection. Since the lake is relatively open, wind and waves are easily formed. During measurement, generally, when it reaches the corresponding measurement point, it directly conducts measurement. When the detection component is at the corresponding measurement point, it is affected by wind and waves and shows a swinging situation in different directions, which is likely to result in inaccurate detection. Summary of the Utility Model

[0004] To improve the measurement accuracy, an embodiment of the utility model provides an automatic lake silt measuring device.

[0005] The embodiment of the utility model adopts the following technical scheme: an automatic lake silt measuring device, including a first housing, and a second housing fixedly installed above the first housing; the first housing floats on the lake water surface, and a receiving cavity is arranged at its bottom, the receiving cavity is far from the second housing, and a measuring mechanism is arranged in the cavity; a propeller thruster is installed on the outer side wall of the first housing and is close to the receiving cavity; a data memory and a communication component are installed in the first housing; an airborne sensor, a processor electrically connected to the airborne sensor, a GPS module electrically connected to the processor, and a motor mechanism electrically connected to the processor are installed in the second housing; a propeller thruster is installed on the outer surface of the second housing; the propeller thruster is close to the first housing and is electrically connected to the motor mechanism; the measuring mechanism includes a gyroscope and an ultrasonic measuring instrument; the gyroscope is installed on the top inner wall of the receiving cavity and is far from the water surface; the ultrasonic measuring instrument is installed on the gyroscope.

[0006] Advantageous Effects: Compared with the prior art, the structure of this solution is completely different; in this solution, a receiving cavity is arranged on the first housing close to the lake water surface, and a measuring mechanism is installed in the receiving cavity, which can prevent the measuring mechanism from being corroded under the water surface for a long time and thus reduce the service life, and can also initially stabilize the measuring mechanism to achieve the improvement of the accuracy of silt measurement.

[0007] Secondly, an integrated gyroscope-stabilized ultrasonic measuring instrument can remain stable under any circumstances, achieving accurate measurement results. At the same time, by designing a housing cavity for installing the ultrasonic sludge level gauge, water surface pollution can be reduced, and the immersion of the measuring mechanism by water can be minimized.

[0008] Preferably, the volume is not greater than 1.5 cubic meters.

[0009] Beneficial effects: Small volume, convenient for carrying and transportation.

[0010] Preferably, the height difference between the ultrasonic measuring instrument and the bottom of the housing cavity is 200 mm.

[0011] Beneficial effects: When the automatic lake sludge measuring device moves on the lake, affected by buoyancy, if it is less than 200 mm, the measuring mechanism is likely to be constantly immersed in water, which will reduce the service life of the measuring mechanism. At the same time, when it is greater than 200 mm, it will instead increase the volume and weight of the automatic lake sludge measuring device and reduce the endurance of the automatic lake sludge measuring device.

[0012] Preferably, the motor mechanism includes a motor, a ternary lithium battery module for driving the motor, and a backup battery module; the motor is electrically connected to the propeller thruster, the ternary lithium battery module, and the backup battery module respectively.

[0013] Beneficial effects: When the area of the lake is large, the backup battery module can provide backup power to accelerate the measurement of the lake sludge. At the same time, when encountering strong winds and waves, using the backup battery and the ternary lithium battery together can increase the propulsion speed of the propeller thruster in a short time, enabling the automatic lake sludge measuring device to travel stably on the water surface.

[0014] Preferably, a photovoltaic panel is also fixedly installed on the second housing, and the photovoltaic panel is far from the first housing; a photovoltaic power storage module is also fixedly installed in the second housing; the photovoltaic power storage module is close to the photovoltaic panel and is electrically connected to the motor mechanism.

[0015] Beneficial effects: The photovoltaic panel can convert light energy into electrical energy to provide power for the automatic lake sludge measuring device, thereby reducing dependence on external energy sources and achieving self-sufficiency in energy. At the same time, the electrical energy provided by the photovoltaic panel can be directly used to drive the motor mechanism through the photovoltaic power storage module, thereby driving the automatic lake sludge measuring device forward. This way of using solar energy for power drive reduces energy conversion losses and improves energy utilization efficiency.

[0016] Preferably, the processor is an STM32 single-chip microcomputer.

[0017] Beneficial effects: The STM32 single-chip microcomputer features high performance and low power consumption. It can not only meet the usage requirements of the automatic lake silt measurement device but also reduce power consumption. Since more power consumption of the automatic lake silt measurement device is concentrated on the propeller thruster, its service life can be extended.

[0018] Preferably, the propeller thruster is a single propeller.

[0019] Beneficial effects: The single propeller has a simple structure, low cost, high efficiency, and small size, making it very suitable for achieving the lightweight effect of the automatic lake silt measurement device.

[0020] Preferably, the structure of the automatic lake silt measurement device is a hull structure.

[0021] Beneficial effects: The hull structure endows the automatic lake silt measurement device with good maneuverability and flexibility, enabling it to move freely in waters such as lakes and easily reach the areas to be measured. At the same time, the hull structure also facilitates the installation of various components, further improving the efficiency and quality of the measurement work.

[0022] Preferably, both the first housing and the second housing are made of fiberglass.

[0023] Beneficial effects: Fiberglass has a low density, but its tensile strength can be close to or exceed that of carbon steel, and its specific strength can be comparable to that of high-grade alloy steel. Fiberglass has good resistance to the atmosphere, water, acids, alkalis, salts at general concentrations, and various oils and solvents, and is suitable for corrosive environments.

[0024] Preferably, the airborne sensors include a radar and a camera.

[0025] Beneficial effects: Further measure the lake to achieve a comprehensive and diversified measurement effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment

[0035] As Figure 1 and 2 shown, this embodiment provides an automatic lake silt measuring device, which is in the structure of a hull and has a volume not greater than 1.5 cubic meters. It includes a first housing 1, and a second housing 2 is fixedly installed on the top of the first housing 1. In this embodiment, both the first housing 1 and the second housing 2 are made of fiberglass. An accommodation cavity 13 is provided at the bottom of the first housing 1. The accommodation cavity 13 is far from the second housing 2, and a measuring mechanism is provided in the cavity. Two propeller thrusters 3 are symmetrically installed at the bottom end of the first housing 1 along the accommodation cavity 13. The bottoms of both sides of the first housing 1 are in an "L" shape, and the two propeller thrusters 3 are respectively located at the bottoms of both sides of the first housing 1. In this embodiment, the propeller thruster 3 is a single propeller and is electrically connected to the motor 26 mechanism. The single propeller is responsible for generating thrust or lift, and the motor 26 provides power for the single propeller. The model of the propeller thruster 3 is Lesong Sulan type marine thruster.

[0036] As Figure 3 shown, a data memory 11 and a communication component 12 are installed in the first housing 1. The memory can adjust the memory according to the actual usage. The communication component 12 includes an antenna, and the antenna is electrically connected to the processor 24. The antenna is fixedly installed on the left inner wall inside the first housing 1, and the data processor 24 is fixedly installed on the right inner wall inside the first housing 1.

[0037] As Figure 4 shown, an airborne sensor 25, a processor 24 electrically connected to the airborne sensor 25, a GPS module 23 electrically connected to the processor 24, and a motor 26 mechanism electrically connected to the processor 24 are installed in the second housing 2. The processor 24 is an STM32 single-chip microcomputer. The airborne sensor 25 includes a radar and a camera. The radar can use electromagnetic waves to monitor the changes of silt in real time, such as sedimentation rate, erosion process, etc. The camera is used to take pictures and measure the nearby water surface. At the same time, the camera has a built-in infrared GPS module 23 and can perform infrared measurement on the water surface. In this embodiment, the processor 24 is an STM32 single-chip microcomputer. AsFigure 4 As shown, the processor 24 is fixedly installed on the left side inside the second housing 2, the on-board sensor 25 is fixedly installed on the right side of the second housing 2, and the on-board sensor 25 can be symmetrically placed with the processor 24. The motor 26 is fixedly installed on the inner wall of the second housing 2, below the on-board sensor 25 and the processor 24. The backup battery module 27 and the ternary lithium battery module 28 are located below the motor 26. While being electrically connected to the motor 26, they are also fixedly installed at the bottom of the inner wall of the second housing 2.

[0038] Specifically, an antenna is installed inside the first housing 1, and a GPS module 23 is installed inside the second housing 2. Placing the two signal transmitters / receivers in different housings can avoid interference between their signals. Moreover, since the data memory 11 occupies a large space, placing it in the second housing 2 will make the second housing 2 too large, easily causing the first housing 1 below the second housing 2 to sink deeper in the water. Therefore, the data memory 11 is installed inside the first housing 1 to achieve a reasonable layout. A wire passing hole is provided on the connection surface between the first housing 1 and the second housing 2 for connecting the components inside the first housing 1 and the components inside the second housing 2 through the wire passing hole. The antenna is electrically connected to the processor 24. The collected measurement data can be remotely sent to the technician through the antenna, and the antenna can also remotely receive the measurement instructions sent by the operator. This measurement instruction is an existing technology. A wire passing hole is also provided at the connection between the first housing 1 and the propeller 3. This wire passing hole is used for wire passing when the propeller 3 and the motor 26 are electrically connected. And since this wire passing hole is prone to water seepage, the size of the wire passing hole matches the size of the wire, and waterproof glue is applied on the surface of the wire passing hole to further achieve the purpose of waterproofing.

[0039] On the top of the outer surface of the second housing 2, a photovoltaic panel 21 is also fixedly installed, and the photovoltaic panel 21 is far from the first housing 1. The photovoltaic panel 21 can absorb light energy. To increase the power generation so that the power generation can meet the power demand consumed by the driving and measurement of the automatic lake silt measuring device, the surface area of the photovoltaic panel 21 is larger than the surface area of the first housing 1. As Figure 4 , on the top of the inner wall of the second housing 2, a photovoltaic power storage module 22 is also fixedly installed; the photovoltaic power storage module 22 is close to the photovoltaic panel 21, one end is connected to the photovoltaic panel 21, and the other end is electrically connected to the motor 26 mechanism. Specifically, it can be electrically connected to the motor 26. The photovoltaic power storage module 22 can convert solar energy into electrical energy and then store the electrical energy, and can provide the electrical energy for the motor 26 mechanism to use. The photovoltaic power storage module 22 is an existing technology, and those skilled in the art can perform conventional designs.

[0040] As Figure 5As shown, the measuring mechanism includes a gyroscope 131 and an ultrasonic measuring instrument 132; the gyroscope 131 is installed on the top inside the accommodation cavity 13. The ultrasonic measuring instrument 132 is installed on the gyroscope 131. The height difference between the ultrasonic measuring instrument 132 and the bottom of the accommodation cavity 13 is 200 mm. Specifically, it is equivalent to the ultrasonic measuring instrument 132 being 200 mm away from the water surface A.

[0041] Usage method of this embodiment

[0042] The operator can store the size of the lake and the longitude and latitude data of the measurement point in the data memory 11 of the automatic lake silt measuring device. The operator can remotely send a measurement instruction to the automatic lake silt measuring device. After receiving the measurement instruction through the antenna, the automatic lake silt measuring device obtains its own longitude and latitude through GPS and drives towards the target measurement point based on its own position. During the driving process, the ternary lithium battery module 28 provides electrical energy for the motor 26, and the motor 26 provides power for the single propeller. The single propeller operates, enabling the automatic lake silt measuring device to travel on the water surface A. The photovoltaic panel 21 converts light energy into electrical energy and drives the motor 26 through the photovoltaic power storage module 22. It can provide a certain driving power for the automatic lake silt measuring device when the ternary lithium battery module 28 has no power. When encountering strong winds and waves, using the backup battery module 27 and the ternary lithium battery together can increase the propulsion speed of the propeller thruster 3 in a short time, enabling the automatic lake silt measuring device to travel stably on the water surface A.

[0043] When the automatic lake silt measuring device travels to the target measurement point, a camera is used to take pictures and measure the nearby water surface to obtain corresponding image measurement data. And the change of the silt is monitored in real time through the radar. At this time, if the water surface A is not calm and the automatic lake silt measuring device is in a swinging state, it is easy to have inaccurate measurements when using the ultrasonic measuring instrument 132 for measurement. In this embodiment, however, the ultrasonic measuring instrument 132 is installed on the gyroscope 131, which can well control the attitude and direction of the ultrasonic measuring instrument 132, enabling the ultrasonic measuring instrument 132 to stably perform precise measurement in the measurement direction to achieve the effect of precise measurement. After obtaining the measurement result, it is stored in the data memory 11 or can also be sent to the operator through the antenna.

[0044] Beneficial effects of this embodiment

[0045] Generally, when the ultrasonic measuring instrument 132 is installed at the bottom of the device, there are no obstructions around the ultrasonic measuring instrument 132. Because once there are obstructions, the ultrasonic waves emitted by the ultrasonic measuring instrument 132 will be absorbed or reflected by the surrounding obstructions, greatly reducing the range of ultrasonic measurement. The reduction of the ultrasonic measurement range will also reduce its measurement accuracy. Although directly installing the ultrasonic measuring instrument 132 at the bottom of the device and directly submerging it underwater can increase the measurement range, due to long-term immersion in water, it will not only shorten the service life of the ultrasonic measuring instrument 132, but also when there are pollutants on the lake surface, they are likely to adhere to the ultrasonic measuring instrument 132, resulting in a further reduction in measurement accuracy. Especially when measuring lake silt, the device often needs to be driven to relatively turbid waters, where there are also abundant pollutants, which are likely to adhere to the ultrasonic measuring instrument 132.

[0046] The structure of this embodiment is different from that of the prior art. A receiving cavity 13 is provided at the bottom of the first housing 1. The ultrasonic measuring instrument 132 is surrounded by the receiving cavity 13. When the ultrasonic measuring instrument 132 is in a static water surface state, the height difference from the water surface is 200 mm, making it difficult for pollutants to adhere. At the same time, the ultrasonic measuring instrument 132 does not need to be submerged in water for a long time, increasing the service life of the ultrasonic measuring instrument 132. To further improve the measurement accuracy, a gyroscope 131 is installed on the ultrasonic measuring instrument 132, enabling the gyroscope 131 to control the attitude and direction of the ultrasonic measuring instrument 132, so that when there are large winds and waves, the ultrasonic measuring instrument 132 can also stably control the measurement direction at the target measurement point to achieve the effect of accurate measurement. At the same time, due to the influence of the receiving cavity 13 at this time, there are obstructions around the ultrasonic measuring instrument 132, and multiple target measurement points can be set to improve the measurement accuracy.
