Description

TECHNICAL FIELD

[0001] The utility model relates to the field of transparency detection, especially a kind of transparency and water depth automatic reading equipment. BACKGROUND

[0002] The transparency of lake, reservoir and other water bodies is generally measured by using Sechi disk measurement, and during measurement, the Sechi disk is placed on a chain and gradually lowered into water until it is almost invisible from above, and then the length of the chain submerged is measured, which is the general guide method for measuring the transparency of lake, reservoir and other water bodies. At present, according to this guide method, some devices for measuring and determining water depth have been designed in the industry, such as the water depth and transparency Sechi disk direct reading instrument disclosed in Chinese patent publication No. CN 109580555 A. The direct reading instrument includes a controller, a 485 bus and a cable, a fixed support, a water pressure sensor, a water depth sensor, a 20 cm diameter disk, a conical counterweight, the 20 cm diameter disk is divided into four equal areas on the front face, and is painted in black and white; the conical counterweight is fixed with the disk, and the disk is connected to the flat end of the fixed support by a rope; the water depth sensor and the water pressure sensor are installed on the vertical end of the fixed support, and their positions are the same as the depth of the disk after being immersed in water; the control 485 bus of the water depth sensor and the water pressure sensor is connected to the controller above the support; the entire support is pulled by the cable, and the 485 bus is not under stress. The water pressure sensor transmits water pressure information to the water surface controller through the 485 bus, converts the water pressure on the disk surface into the vertical distance from the disk surface to the water surface, and displays "water quality transparency XXX.XX meters" on the display screen, accurate to the nearest centimeter and taking two decimal places; the water depth sensor also transmits depth information to the water surface controller through the 485 bus, and the water surface controller obtains the actual water depth of the water area by accumulating the data of the water depth sensor and the distance data of the water pressure sensor, and displays "actual water depth XXX.XX meters" on the display screen, accurate to the nearest centimeter and taking two decimal places. This direct reading instrument can directly read out the water quality transparency and the actual water depth, and when in use, only needs to drive a ship to the measurement area and then lower the Sechi disk direct reading instrument. However, when using this Sechi disk direct reading instrument, the actual water depth and water quality transparency are recorded when the black and white disk (Sechi disk) cannot be seen, and the Sechi disk is difficult to adjust the length of the rope to the critical position of being visible and invisible, resulting in a poor user experience.

[0014] Figure 2 This is a top view of the automatic transparency and water depth reading device of Embodiment 1 of this utility model during use. Detailed Implementation

[0015] This embodiment is an automatic transparency and water depth reading device, such as... Figure 1 As shown, in practical applications, it is generally placed on a boat, and the boat is rowed to a suitable location in a lake or reservoir to test the water quality. In this embodiment, the automatic transparency and water depth reading device on the boat includes a Syracuse disk 1, a first sonar sensor 2, a second sonar sensor 3, a processor, and a display screen 4. When the Syracuse disk 1 is submerged in water and cannot be observed, the first sonar sensor 2 measures the distance from the water surface to the Syracuse disk 1, and the second sonar sensor 3 measures the water depth. The processor is connected to the first sonar sensor 2 and the second sonar sensor 3, processes the received data, and displays it on the display screen 4. In this embodiment, a telescopic arm 5 is also included. The Syracuse disk 1 is installed at the end of the telescopic arm 5, and the first sonar sensor 2 is movably installed on the telescopic arm 5. When the Syracuse disk 1 is submerged in water and cannot be observed, it is close to the water surface. The probe of the second sonar sensor 3 is installed at the end of the telescopic arm 5 below the Syracuse disk 1.

[0016] In this embodiment, a metal rod that reaches 10 meters when fully extended is used as the telescopic arm 5. A Cyclone disk 1 is installed at the end of the telescopic arm 5, so that the Cyclone disk 1 is installed perpendicular to the metal rod. In practice, the Cyclone disk 1 can be fixed on the innermost section of the telescopic metal rod. The center of the Cyclone disk 1 coincides with the center of the innermost metal rod. When the telescopic arm 5 is stored, after all the sections of the metal rod are retracted, the metal rod of the email is still extended, and the Cyclone disk 1 can remain on it.

[0017] In this embodiment, for ease of use of the telescopic arm 5, a handle 7 is also provided on the telescopic arm 5, such as... Figure 1The handle 7 is arranged at the end of the outermost telescopic metal rod, perpendicular to the metal rod. A circuit board can be accommodated in the handle 7. The processor and peripheral circuits such as a memory can be arranged on the circuit board. A communication circuit for communication between the processor and the two sonar sensors can also be arranged on the circuit board. In practice, the two sonar sensors are sonar sensors with built-in Bluetooth wireless circuits. A Bluetooth communication module is also arranged on the circuit board in the handle 7. Thus, wireless communication between the two sonar sensors and the processor can be achieved. The data detected by the sonar sensors is transmitted in real time to the processor through the Bluetooth wireless communication module. The processor can display the data on the display screen 4 after processing. In practice, since the telescopic arm 5 is only 10 meters long at most, which is sufficient for all lakes and reservoirs in the region, the two sensors can be connected to the processor at the handle through wires when installed on the telescopic arm, so as to directly transmit the data collected by the sonar sensors to the processor. Of course, there are many communication methods between the sonar sensors and the processor. For example, when there is WIFI on the boat, the sonar sensors and the processor can also communicate through WIFI. These are mature communication technologies.

[0018] In the embodiment, the camera 6 is also included. When the Sei disk 1 is immersed in water, the camera 6 is closely attached to the water surface. The camera 6 is connected to the processor, and the output image is displayed on the display screen 4. In practice, the communication between the camera 6 and the processor can be the same as the communication between the sonar sensors and the processor. Wired communication or wireless communication such as Bluetooth and WIFI can be used. In the embodiment, the memory on the circuit board in the handle 7 also stores a comparison image. The comparison image is an image captured by the camera 6 when the Sei disk 1 is not observed to be immersed in water. Under the control of the processor, the comparison image and the image captured by the camera 6 in real time are displayed on the display screen 4 at the same time. In the embodiment, the camera 6 is a camera with a fill light. When used, the camera 6 is attached to the water surface, and then the length of the telescopic metal rod is adjusted to observe the Sei disk 1 in the water until it cannot be seen. In practice, the camera 6 and the first sonar sensor 2 are movably installed on the telescopic arm 1, and their distance from the water surface can be adjusted to be close to the water surface. In the display screen 4, the image captured by the camera 6 in real time is compared with the comparison image until the two images are basically consistent, that is, the Sei disk 1 reaches the measured depth. In practice, an automatic comparison module is also included on the circuit board. The automatic comparison module automatically compares the comparison image and the image captured by the camera 6 in real time. The processor compares the two images. If the difference between the image captured by the camera 6 in real time and the original standard image is within the set range, it is considered that the transparency measurement can be performed. The real-time comparison module can be programmed by a person skilled in the art or purchased on the market. It is a very mature technology. A person skilled in the art can choose as desired.
