Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figures 1-12 As shown, this utility model embodiment provides a multifunctional mud sampler, including a left half mud sampling grab 11, a right half mud sampling grab 12, a first lifting handle 14-1, a second lifting handle 14-2, a lifting rope 10, a first traction rope 20, a rope switcher, a second traction rope 40, a camera 50, a lighting lamp 80, a temperature, salinity, and depth meter 60, a counterweight 70, a water sampling module 90, a hydroacoustic beacon 110, and a battery 120. The tops of the left half mud sampling grab 11 and the right half mud sampling grab 12 are hinged together to form the mud sampling grabs of the mud sampler.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a first lifting handle 14-1 is connected to the left half of the mud-collecting grab bucket 11, and a second lifting handle 14-2 is connected to the right half of the mud-collecting grab bucket 12. The first lifting handle 14-1 has a first top through hole 15-1 and a first bottom through hole 15-2 at its two ends, respectively. The second lifting handle 14-2 has a second top through hole 15-3 and a second bottom through hole 15-4 at its two ends, respectively. The first top through hole 15-1 and the second top through hole 15-3 are connected to the two ends of a first traction rope 20, and a lifting rope 10 is connected to the middle loop hole of the first traction rope 20. The bottom of the lifting rope 10 is connected to a second traction rope 40 via a rope switcher, and the two ends of the second traction rope 40 are connected to the first bottom through hole 15-2 and the second bottom through hole 15-4, respectively.

[0031] The left half of the mud-collecting grab bucket 11 and the right half of the mud-collecting grab bucket 12 are equipped with multiple vents 102, instrument supports 103, cameras 50, a temperature, salinity, and depth (TDM) meter 60, counterweights 70, lighting lamps 80, a water sampling module 90, an acoustic beacon 110, and batteries 120. The multiple vents 102 are located on the upper and side surfaces of the left half of the mud-collecting grab bucket 11 and the right half of the mud-collecting grab bucket 12; the vents 102 are used to drain water from the grab bucket cavity when the grab bucket is closed. A set of cameras 50 and a set of lighting lamps 80 are respectively mounted on the counterweight 70 and the instrument support 103; the cameras 50 and the lighting lamps 80 are used to capture seabed conditions from different perspectives. The TDM meter 60 and the acoustic beacon 110 are used to collect seabed temperature, salinity, depth, and sampling coordinates.

[0032] like Figure 4As shown, the pull rope switcher includes a sleeve assembly 30 and a lifting ring rod assembly 130 coaxially mounted on the sleeve assembly 30. The sleeve assembly 30 includes a sleeve 31, a spring 34, and a brake push rod 33; the brake push rod 33 is mounted on both sides of the bottom of the sleeve 31, the spring 34 is sleeved on the axial surface of the brake push rod 33, and the brake push rod 33 is elastically connected to the sleeve 31 through the spring 34; the top of the sleeve 31 has rope holes 32 on both sides, wherein the lifting rope 10 passes through the middle loop hole of the first traction rope 20, and the bottom end of the lifting rope 10 is tied to the rope holes 32 on both sides of the top of the sleeve 31.

The hollow frustum 135 is held in the sleeve 31, and the bottom of the hollow frustum 135 abuts against the end of the brake push rod 33. When there is a large contact force between the upper surface of the brake push rod 33 and the lower surface of the hollow frustum 135, the float 134 cannot push the brake push rod 33 radially away under the action of buoyancy. When the upper surface of the brake push rod 33 only makes slight contact with the lower surface of the hollow frustum 135, the float 134 will push the brake push rod 33 radially away under the action of buoyancy. The middle loop hole of the second traction rope 40 is fixed to the eye ring hole 131. Preferably, the float base 133 is welded to the ring rod 132. The float 134 is made of material with a density of less than 1000 kg / m³. 3 Made of materials.

[0034] Figure 5 Combination Figure 1 The left half mud-collecting grab bucket 11 and the right half mud-collecting grab bucket 12 are two quarter-hollow cylinders with the same structure and size.

Figure 8 This is a schematic diagram of the structure of a 60°C salinity depth meter. Figure 9 This is a schematic diagram of the underwater acoustic beacon 110. Figure 10 This is a schematic diagram of the water intake module 90. Figure 11 This is a schematic diagram of the lifting rope 10. Figure 12 This is a schematic diagram of the first traction rope 20.

[0036] Preferably, such as Figure 10 As shown, the water sampling module 90 includes a syringe 91 and an electric actuator 92, with the electric actuator 92 mounted on the end of the syringe 91. Figure 5As shown, the left half of the mud-collecting grab bucket 11 and the right half of the mud-collecting grab bucket 12 are hinged together by a pivot 101. A counterweight 70 is bolted to both the left and right halves of the mud-collecting grab bucket 11 and 12, with the purpose of closing the grab buckets under their own weight. The bottom end of the lifting rope 10 is attached to a sleeve 031, and then passes through the central loop of the first traction rope 20. Both ends of the first traction rope 20 are attached to the ends of the first and second lifting handles. A battery 120 and a water-collecting module 90 are also installed on the mud-collecting grab bucket. A camera 50, a light 80, and a hydroacoustic beacon 110 are bolted to the instrument bracket 103. A camera 50, a light 80, and a temperature, salinity, and depth meter 60 are bolted to the counterweight 70.

[0037] This utility model embodiment also provides a method for using a multifunctional mud sampler, including the following steps:

[0038] Step 1: First, reset the pull rope switch, connect the sleeve assembly 30 and the lifting ring rod assembly 130 together, and put the water sampling module 90 in the initial state. The electric push rod 92 extends to the bottom of the syringe 91.

[0039] Step 2: Then, the mud sampler is slowly lowered to the bottom of the water using the lifting rope 10. During this process, due to the force on the lifting rope 10, the upper surface of the brake push rod 33 has a large contact force with the lower surface of the hollow truncated cone 135, and the float 134 cannot push the brake push rod 33 radially away under the action of buoyancy. When the mud sampler touches the bottom, the lifting rope 10 slackens and is no longer under force. At this time, the upper surface of the brake push rod 33 only makes slight contact with the lower surface of the hollow truncated cone 135, and the float 134 will push the brake push rod 33 radially away under the action of buoyancy, causing the brake push rod 33 to lose its braking effect. Since the second traction rope 40 is in a slack state, the left half mud sampler grab bucket 11 and the right half mud sampler grab bucket 12... The bucket 12 will close naturally under the action of the counterweight 70. At the same time, the water sampling module 90 retracts through the electric push rod 92 to suck the bottom water into the syringe 91, completing the water sampling operation. Furthermore, the various instrument modules on the mud sampler complete the corresponding data collection work. Among them, the counterweight 70 and the instrument support 103 are respectively equipped with a set of cameras 50 and lighting lamps 80, which are used to capture the seabed conditions under different fields of view. The temperature, salinity and depth gauge 60 and the underwater acoustic beacon 110 are used to collect seabed temperature, salinity, depth and sampling coordinates. The vent holes 102 on the upper surface and side of the left half mud sampling bucket 11 and the right half mud sampling bucket 12 are used to drain the water in the bucket cavity when the bucket is closed.

[0040] Step 3: After all the work is completed, the mud sampler is lifted. At this time, the lifting rope 10 is tightened again. Since the brake push rod 33 loses its braking effect, the sleeve assembly 30 will separate from the lifting ring rod assembly 130. The second traction rope 40 no longer has a pulling force. Instead, the first traction rope 20 begins to bear the force. Under the pulling force of the first traction rope 20, the mud sampler grab bucket closes tightly and is lifted out of the water, completing the mud sampling operation.

[0041] The working process of a multifunctional mud sampler in this embodiment is as follows: First, the pull rope switcher is reset, that is, the sleeve assembly 30 is connected to the lifting ring rod assembly 130, and the water sampling module 90 is in the initial state, and the electric push rod 92 is extended to the bottom of the syringe 91. The mud sampler is slowly lowered to the bottom of the water by the lifting rope 10. At this time, each instrument module will automatically complete its own task, including mud sampling, water sampling and various data acquisition. Then, the mud sampler is lifted out of the water by the lifting rope 10 to complete the mud sampling operation.

[0042] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
