Description

Technical Field

[0001] The present invention relates to the field of underwater sediment layers and biological detection, and particularly relates to an anchor-type underwater detection device. Background Art

[0002] Currently, in wetland and lake scientific research work, it is necessary to study underwater sediment layers and organisms, and the collection of environmental element data is an important task. Current scientific research data shows that underwater detection is more difficult than ground detection, and the data abundance is far less than surface observation items. The reasons are as follows: Firstly, due to the limited distribution of the water surface, and secondly, the high requirements for equipment and the great pressure on scientific research costs. The existing method is to collect samples centrally and then analyze them in the laboratory later, but the environmental background data of the samples often cannot be obtained in a timely manner, or only simple and displaced measurements can be carried out, or even abandoned. And the in-situ research method is difficult to implement due to conditions. Summary of the Invention

[0003] In order to solve the problems of the existing method of collecting samples centrally and then analyzing them in the laboratory later, where the environmental background data of the samples often cannot be obtained in a timely manner, or only simple and displaced measurements can be carried out, or even cannot be obtained, and the in-situ research method is difficult to implement due to conditions, the present invention provides an anchor-type underwater detection device, and the technical solution to solve this problem is as follows:

[0004] An anchor-type underwater detection device of the present invention is composed of a suspension cable lock point, an anchor hanger, a locking nut, a limit bolt, a limit chassis, an anchor, a detector, and a recorder. The suspension cable lock point is arranged above the anchor hanger, the lower part of the anchor hanger is arranged on the anchor, a limit bolt hole is opened in the center of the anchor, the limit bolt is assembled on the anchor in cooperation with the locking nut through the limit bolt hole, a limit chassis is arranged at the lower end of the limit bolt, the detector is arranged on the upper plane of the anchor, multiple groups of probe guide holes are opened on the anchor, the probe of the detector extends to the lower part of the limit chassis through the probe guide holes, and the recorder is connected to the upper end of the wire;

[0005] The detector is composed of a wire, a detection chip, and a probe. The wire is connected to the detection chip, and a probe is arranged below the detection chip.

[0006] An anchor - type underwater detection device of the present invention adopts the principle of "ship anchor", endows the detector function to the device (anchor body). The device can be suspended in water or sink to the bottom of the lake. When detecting at the bottom of the lake, the depth of the probe inserted into the sediment layer can be controlled by adjusting the mechanical structure of the anchor body, so as to accurately obtain environmental data at different sediment depths. It solves the problems of synchronously collecting environmental element data during underwater sample collection, improving the accuracy of in - situ environmental data collection, providing favorable data support for subsequent experimental analysis. The device has good portability, is relatively convenient to switch positions, takes a short time to balance the environment, is conducive to providing relatively accurate and reliable support for spatial pattern data, forming a regional effect, and has the advantage of low manufacturing cost.

DETAILED DESCRIPTION OF THE INVENTION

[0008] DETAILED DESCRIPTION OF THE INVENTION I: Combine Figure 1 to describe this embodiment. This embodiment is composed of a suspension cable lock point 1, an anchor body hanger 2, a locking nut 3, a limit bolt 4, a limit chassis 5, an anchor body 6, a detector 7 and a recorder 8. The suspension cable lock point 1 is arranged above the anchor body hanger 2, the lower part of the anchor body hanger 2 is arranged on the anchor body 6. A limit bolt hole 6 - 2 is opened in the center of the anchor body 6. The limit bolt 4 is assembled on the anchor body 6 through the limit bolt hole 6 - 2 in cooperation with the locking nut 3. A limit chassis 5 is arranged at the lower end of the limit bolt 4. The detector 7 is arranged on the upper plane of the anchor body 6. Multiple groups of probe guide holes 6 - 1 are opened on the anchor body 6. The probe 7 - 3 of the detector 7 extends to the lower part of the limit chassis 5 through the probe guide hole 6 - 1. The input end of the recorder 8 is connected to the upper end of the wire 7 - 1;

[0009] The detector 7 described above is composed of a wire 7 - 1, a detection chip 7 - 2 and a probe 7 - 3. The wire 7 - 1 is connected to the detection chip 7 - 2, and the probe 7 - 3 is arranged below the detection chip 7 - 2.

[0010] DETAILED DESCRIPTION OF THE INVENTION II: Combine Figure 1 , Figure 2 and Figure 3 to describe this embodiment. The detector 7 described in this embodiment adopts a double - probe, triple - probe and quadruple - probe according to different functions.

[0011] DETAILED DESCRIPTION OF THE INVENTION III: Combine Figure 1 , Figure 2 and Figure 3Describe this embodiment. The probe guide hole 6-1 described in this embodiment is an insulating hole. The insulating hole is formed by riveting an insulating material kit, spraying insulating powder, or passivating treatment using material properties. This prevents the probe 7-3 from conducting electricity with the main board signal, which may cause the detector 7 to malfunction or give inaccurate measurements. During processing, tolerances should be reserved according to different insulation schemes to meet the sliding requirements of the probe 7-3 and also play a guiding and supporting role.

[0012] Specific Embodiment Four: Combine Figure 1 、 Figure 2 Describe this embodiment. The anchor body 6 described in this embodiment is a square plate or a circular plate, made of steel plate or aluminum plate, and the thickness of the anchor body 6 is 1-5 cm.

[0013] Specific Embodiment Five: Combine Figure 1 Describe this embodiment. The detector described in this embodiment is of the N-P-K, PH, or T-H-EC model.

[0014] Specific Embodiment Six: Combine Figure 1 、 Figure 2 Describe this embodiment. The recorder described in this embodiment uses PR-3002-TRREC-N01.

[0015] Specific Embodiment Six: Combine Figure 4 Describe this embodiment. The wire 7-1 of the detector 7 in this embodiment is coupled with the suspension cable in a row.

[0016] Due to the complex underwater environment, it is easy to accidentally touch hard objects and cause damage, and the detector probe is very fragile and vulnerable. Therefore, a probe retraction mechanism can also be designed. For example, when encountering a relatively hard lake bottom, the strength of the probe certainly cannot bear the total weight of the anchor body, which may cause bending deformation and damage. The rebound mechanism is that when the reaction force reaches a certain number of newtons (the external force that does not damage the probe), the probe 7-3 will automatically retract to avoid probe damage, and the mechanism design can facilitate resetting.

[0017] Working principle and usage method of the device (taking a lake as an example):

[0018] First step, preparation work. Before the device enters the water, use a depth sounding tool to detect the approximate depth from the water surface to the lake bottom, use an ultrasonic device to detect the geological conditions of the lake bottom (whether it is sandy, rocky, or muddy), and select the detection depth required to penetrate the sediment layer according to the geological conditions of the lake bottom. According to the detection target, adjust the relative distance between the limit chassis 5 and the main board of the anchor body 6 to ensure the depth at which the probe 7-3 penetrates the sediment layer for detection. The detection depth can be accurate to the millimeter level. Lock the lock nut 3 and the limit bolt 4 at the required position;

[0019] Step 2: Connect and lock the supporting suspension cable 9 to the anchor body suspension cable locking point 1. Select a detector based on the detection index data, and select the corresponding installation position of the anchor body plate according to the number of needles of the detector. Couple and arrange the detector wire 7-1 with the suspension cable 9. Connect the recorder supporting the detector 7 to the other end of the wire 7-1 using PR-3002-TRREC-N01. Each connection point of the detector 7 and the wire 7-1 should meet the IP68 protection level to ensure the long-term operation of the detector;

[0020] Step 3: Select a suitable anchor dropping point according to the data obtained in Step 1 and lower the device;

[0021] During the lowering process, control the cable release speed to avoid damaging the detector probe 7-3. At the moment of touching the bottom, make every effort to ensure that the device is vertical and avoid horizontal movement of the device to ensure accurate positioning of the device;

[0022] Step 4: After the device is positioned, turn on the recorder 8 to collect environmental element data. During the collection process, ensure the range of the hull drifting on the water surface, always keep the suspension cable 9 and the wire 7-1 in a slack state, and ensure sufficient power supply for the instrument;

[0023] Step 5: During the detection and collection period, if other samples (water samples, sediment, microorganisms, planktonic animals and plants, aquatic animals and plants) are collected, it is necessary to ensure the time synchronization of each instrument and accurately record the start and end times of sampling for subsequent data synchronization processing.

[0024] The above embodiments only describe the specific implementation manners of the present invention and do not limit the scope of the present invention. Those skilled in the art can make various modifications and changes based on the prior art. Without departing from the design spirit of the present invention, they should all fall within the protection scope determined by the claims of the present invention.
