Description

Technical Field

[0001] The invention relates to the technical field of ocean surveying and mapping, in particular to an above-water distance surveying instrument for ocean engineering surveying and mapping. Background Art

[0002] Marine engineering refers to new construction, reconstruction and expansion projects that are aimed at developing, utilizing, protecting and restoring marine resources, and the main body of the project is located on the seaward side of the coastline. It is generally believed that the main content of marine engineering can be divided into two parts: resource development technology and equipment and facility technology. Marine surveying and mapping engineering has become an important part of marine engineering scientific research, and its technical difficulty and precision requirements are getting higher and higher. The measurement accuracy of marine environment such as wind, waves and currents directly determines the accuracy of marine engineering tests. Long-term, continuous and fixed-point detection of marine hydrological environment mostly uses echo sounders to survey water distances. The working principle of the echo sounder is to use a transducer to emit sound waves in the water. When the sound waves encounter obstacles and are reflected back to the transducer, the distance between the obstacle and the transducer can be obtained based on the round-trip time of the sound waves and the speed of sound wave propagation in the measured waters.

[0003] However, the existing water distance surveying instruments cannot maintain a stable state during use and are prone to shaking with the fluctuations of the sea surface, thereby affecting the survey efficiency and accuracy. In addition, the protection effect is poor, which can easily cause the surveying device to roll over, affecting the survey efficiency. Summary of the invention

[0018] (III) Beneficial effects

[0019] The present invention provides an underwater distance surveying instrument for marine engineering surveying and mapping. It has the following beneficial effects:

[0020] 1. When the device shakes, the bubbles in the two levels will move in the leveling liquid, causing the infrared rays emitted by the infrared emitting device to change. The infrared receiving device controls the first water pump or the second water pump to work according to the change of the infrared rays, so that the supporting floating plate remains horizontal and the shaking of the supporting floating plate is reduced. At the same time, the surveying instrument body is connected by a connecting rope, which can prevent the shaking of the device from driving the movement of the surveying instrument body, thereby effectively improving the measurement environment of the surveying instrument body.

[0021] 2. When at least two water immersion sensors are submerged in water, the water immersion sensors will transmit a signal to the gas generator. After receiving the signal, the gas generator will ignite the gas generator to produce a large amount of gas. After being filtered and cooled, the gas enters the folding airbag, causing the airbag to expand rapidly in a very short time, thereby increasing the buoyancy of the device and effectively preventing the device from sinking to the bottom of the sea.

[0022] 3. The weight ball and weight liquid of the device can effectively lower the center of gravity of the device, thereby reducing the risk of the device tipping over. BRIEF DESCRIPTION OF THE DRAWINGS
