DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Figure 1 It is a schematic diagram of the overall structure provided by an embodiment of the utility model; Figure 2 It is a schematic diagram of the structure of a first data cable provided by an embodiment of the utility model; Figure 3 Schematic diagram of the cross section of the probe provided by the embodiment of the utility model. Figures 1 to 3 An underwater geological detection device shown in the figure includes: a box body 1, a probe rod 2 and a data cable 3, the probe rod 2 is vertically and slidably inserted into the box body 1, a sensor 4 is arranged at the bottom of the probe rod 2, the data cable 3 includes a first data cable 31 and a second data cable 32, the first data cable 31 is spirally coiled between the top of the probe rod 2 and the top of the box body 1, the second data cable 32 is arranged inside the probe rod 2, one end is connected to the sensor 4, and the other end is connected to the first data cable 31, a data acquisition cabin 5 is arranged inside the box body 1, and the sensor 4 is connected to the data acquisition cabin 5 signal through the data cable 3.

[0026] For example, in the embodiment of the utility model, the device is hoisted into the water by the hoisting cable on the hull until the box 1 is located on the seabed. At this time, the box 1 is also connected with a measurement and control cable for controlling the movement of the probe rod 2 in the vertical direction. When the box 1 is stable, the probe rod 2 is controlled to move in the vertical direction, so that the sensor at the bottom of the probe rod 2 extends into different geological layers to collect data. The collected data is transmitted to the data collection cabin 5 inside the box 1 through the data cable 3 for storage. After the operation is completed, the data collection cabin 5 is extracted for analysis. The data cable 3 is divided into a first data cable 31 and a second data cable 32. The second data cable 32 is located inside the probe rod 2, so it will not interfere with other cables. The first data cable 31 is coiled on the probe rod 2 and is located between the top of the probe rod 2 and the top of the box 1. In the process of the probe rod 2 probing down, due to its spring-like structure, it will only be compressed and coiled between the top of the probe rod 2 and the top of the box 1, and will not interfere with other cables. Compared with the traditional technology, during the operation, the loose measurement and control cable and the data cable may be entangled with the suspension cable. By setting this structure, the data cable 3 will not interfere with other cable structures, thereby reducing the probability of accidents caused by cable entanglement.

[0027] An underwater geological exploration device provided by an embodiment of the utility model comprises a data cable 3 consisting of a first data cable 31 and a second data cable 32, and the second data cable 32 is arranged inside the probe rod 2, and the first data cable 31 is arranged as a spring-mounted structure. After the operation starts, the probe rod 2 moves downward to explore the geology at the bottom of the seabed, collects information through the sensor 4 and transmits it to the data acquisition cabin 5 for storage through the data cable 3. Since the second data cable 32 is arranged inside the probe rod 2, it will not be entangled with the suspension cable when the device is lowered, and the first data cable 31 is a spring-like structure. During the downward exploration of the probe rod 2, the first data cable 31 is always between the top of the probe rod 2 and the top of the box body 1, so that the data cable 3 will not interfere with the suspension cable, thereby reducing the possibility of entanglement between cables during operation, which can effectively solve the problem of high degree of operation danger in the prior art.

[0028] Optionally, a penetration mechanism 6 is provided in the box body 1, and the penetration mechanism 6 includes two transverse hydraulic cylinders 61 and two longitudinal hydraulic cylinders 62. The two longitudinal hydraulic cylinders 62 are arranged on both sides of the probe rod 2, and the transverse hydraulic cylinder 61 is arranged at the end of the piston rod of the longitudinal hydraulic cylinder 62. The end of the piston rod of the transverse hydraulic cylinder 61 is provided with a clamp 63, and the opening of the clamp 63 is set toward the probe rod 2 and matches the probe rod 2.

[0029] For example, in the embodiment of the present utility model, Figure 1As shown, by controlling the movement of the piston rods of the two transverse hydraulic cylinders 61, the clamping claw 63 can clamp the probe rod 2, and then by controlling the movement of the longitudinal hydraulic cylinder 62, the probe rod 2 can be moved upward or downward for a distance. When the maximum stroke of the longitudinal hydraulic cylinder 62 is reached, the piston rod of the transverse hydraulic cylinder 61 is controlled to move in the opposite direction, so that the clamping claw 63 is separated from the probe rod 2, and the longitudinal hydraulic cylinder 62 is controlled to move again. After the maximum stroke of the directional movement is reached, the piston rods of the two transverse hydraulic cylinders 61 are controlled to move, so that the clamping claw 63 can clamp the probe rod 2. The above operations are repeated, and the continuous upward or downward movement of the probe rod 2 is realized to realize the geological exploration of the sensor 4. By setting this structure, the structure is simple and the operation is convenient, and the movement control of the probe rod 2 can be realized, which improves the convenience of operation of the device.

[0030] Optionally, the probe rod 2 is a cylindrical structure, the clamping jaw 63 is an arc-shaped clamping jaw, and the clamping jaw 63 matches the circumferential surface of the probe rod 2 .

[0031] Exemplarily, in an embodiment of the utility model, the clamping jaw 63 is set to be an arc-shaped clamping jaw that matches the circumferential surface of the probe rod 2, which can increase the contact area between the clamping jaw 63 and the probe rod 2. Compared with the use of a "V"-shaped clamping jaw that only contacts two surfaces with the probe rod 2, the clamping jaw 63 in this embodiment can fit the probe rod 2 to the greatest extent, thereby increasing the friction force during the clamping and pulling process of the probe rod 2, and improving the stability of the device.

[0032] Optionally, a first fixing seat 71 is disposed on the top of the probe rod 2 , and a second fixing seat 72 is disposed on the top of the box body 1 .

[0033] For example, in the embodiment of the present utility model, Figure 1 and Figure 2 As shown, a wire clamping hole can be set on the first fixing seat 71 and the second fixing seat 72, and the data cable 3 is passed through the wire clamping hole for setting, so that the data cable 3 is fixed on the first fixing seat 71 and the second fixing seat 72. The positions of the first fixing seat 71 and the second fixing seat 72 are at the turning point of the layout position of the data cable 3. The data cable 3 is fixed at the turning point, so that the first data cable 31 can be fixed on the device more stably, preventing excess cables from interfering with other cables at the turning point, and further reducing the probability of accidents caused by cable entanglement.

[0034] Optionally, the first fixing seat 71 and the second fixing seat 72 are disc structures, and the area of ​​the second fixing seat 72 is larger than that of the first fixing seat 71 .

[0035] Exemplarily, in an embodiment of the utility model, during the downward movement of the probe rod 2, the first data cable 31 will be compressed, and the cable will coil on the second fixing seat 72 under the action of gravity, so that the first data cable 31 is accumulated on the second fixing seat 72. By increasing the area of ​​the second fixing seat 72, the second fixing seat 72 can provide more stable support for the first data cable 31 in a compressed state, thereby further improving the stability of the device.

[0036] Optionally, mounting holes 11 are provided at the top and the bottom of the box body 1 , the probe rod 2 is inserted through the mounting holes 11 , and a sealing ring 8 is provided in the mounting holes 11 .

[0037] For example, in the embodiment of the present utility model, Figure 1 As shown, by providing a sealing ring in the mounting hole 11, it is possible to prevent water from entering the interior of the box body 1 when the probe rod 2 moves through the box body 1. By providing the sealing ring, the sealing performance of the device is improved.

[0038] Optionally, a wiring groove 91 along the direction of the probe rod 2 is provided in the probe rod 2 , and the second data cable 32 is arranged in the wiring groove 91 .

[0039] For example, in the embodiment of the present utility model, Figure 3 As shown, the wiring groove 91 can provide a stable laying channel for the second data cable 32. By setting the wiring groove 91 inside the probe rod 2, the second data cable 32 can be more stably fixed in the wiring groove 91. By setting the wiring groove 91, the stability of the device is further improved.

[0040] Optionally, a plurality of fixing cards 92 are provided in the wiring groove 91 , and the plurality of fixing cards 92 are evenly spaced apart along the direction of the probe rod 2 .

[0041] For example, in the embodiment of the present utility model, Figure 3 As shown, the fixing card 92 is provided with a movable buckle, and the second data cable 32 can be inserted therein. The movable buckle can be interference fit with the second data cable 32, so that the second data cable 32 is more stably fixed in the fixing card 92. By arranging the fixing card 92 in the wiring groove 91, the stability of the device is further improved.

[0042] Optionally, a chamfer is provided between the top end surface and the side wall of the box body 1 .

[0043] For example, in an embodiment of the utility model, after the operation of the device is completed, the device needs to be lifted out of the water. By setting a chamfer on the top of the box 1, the resistance in the process of lifting the box 1 out of the water can be reduced, so that the device can be recovered more easily, thereby further improving the operational convenience of the device.

[0044] Optionally, the housing 1 is made of titanium alloy.

[0045] For example, in the embodiment of the utility model, the box 1 is made of titanium alloy. Titanium alloy has the characteristics of high strength and good corrosion resistance. The high strength can physically protect the equipment inside the box 1. At the same time, the high corrosion resistance can prevent the box 1 from being corroded by seawater and causing damage to its internal equipment, thereby increasing the service life of the device.
