Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of clamshell sampling devices, specifically a novel clamshell sampling device. Background Technology
[0002] The clamshell sampling device is a specialized piece of equipment used in various fields such as environmental monitoring, marine research, and geological exploration. It is named for its clamshell-like opening and closing mechanism.
[0003] In marine geological research, it is necessary to collect samples such as rocks and sediments from the seabed to analyze marine geological structures, stratigraphic evolution, and mineral resource distribution. Clamshell sampling devices can penetrate deep into the seabed and accurately collect different types of geological samples, providing important physical evidence for marine geological scientific research.
[0004] Underwater sampling is typically carried out using specialized samplers installed on shipboard facilities. These samplers consist of a support frame mounted on the ship's deck, a winch mounted on the deck, and a grab bucket that is lifted, lowered, and moved by the winch. The grab bucket is equipped with a hydraulic opening and closing control device. During underwater sampling, the winch lowers the grab bucket to the bottom of the water, and then the hydraulic opening and closing control device moves the grab bucket from the open to the closed state, thus capturing the soil sample from the bottom. The winch then lifts the grab bucket back to the surface, and the hydraulic opening and closing control device releases the soil sample from the grab bucket. The construction personnel then analyze and record the soil conditions obtained on-site.
[0005] Regarding the existing related technologies, the inventors believe that the following defects exist: the existing samplers are relatively specialized and require equipment adjustment before construction, which is time-consuming; secondly, the operation process is relatively complicated, resulting in low sampling efficiency. Utility Model Content
[0006] To address the technical problems of existing samplers being too specialized, requiring equipment adjustment before construction, which is time-consuming, and having a complex operation process, resulting in low sampling efficiency, this utility model provides a novel clamshell sampling device.
[0007] This utility model is achieved using the following technical solution: a novel clamshell sampling device, comprising a first bucket and a second bucket, one end of the first bucket and one end of the second bucket being hingedly connected, a first flap being hingedly connected to the top of the first bucket, a second flap being hingedly connected to the top of the second bucket, a connecting rope being fixedly connected to the top of the first and second flaps, a steel wire rope being fixedly connected to the middle of one end of the second bucket, a fixing plate being fixedly connected to the top of the steel wire rope, a pull hook being rotatably connected inside the fixing plate, a hook head being fixedly connected to one end of the pull hook, and the middle of the connecting rope being located inside the hook head.
[0008] Preferably, a connecting ring is provided at the top of the fixing plate, and a fixing shaft is provided in the middle of the fixing plate.
[0009] Preferably, the fixed shaft is rotatably connected inside the hook.
[0010] Preferably, one end of the hook is fixedly connected to a counterweight.
[0011] Preferably, the top of the second bucket is fixedly connected to a fixed base, and the bottom ends of the second flap are fixedly connected to rotating shafts, which are rotatably connected inside the fixed base.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, by pulling the connecting ring upwards, the connecting ring will move the fixed plate, making the fixed plate vertical. Then, the middle part of the connecting rope is looped inside the hook head, and the two ends of the connecting rope will pull the first flap and the second flap respectively. By continuing to pull the connecting ring upwards, under the gravity of the first bucket and the second bucket, the connecting rope will move the hook head to the bottom side of the fixed plate, thereby placing the first bucket and the second bucket in the open state at the bottom of the water for sampling.
[0014] When this utility model is in use, when the first and second buckets are placed at the bottom of the water, the weight of the counterweight will be greater than the weight of the connecting rope inside the hook. The counterweight will drive the hook to rotate, and the hook will drive the hook head to move upward, causing the connecting rope to detach from the inside of the hook head. Finally, by pulling the connecting ring, the connecting ring will drive the fixing plate, wire rope, second bucket and first bucket to move upward. Under the action of gravity, the first and second buckets will approach each other and close to sample the mud at the bottom of the water. The operation is simple and convenient.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0020] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a clamshell sampling device includes a first bucket 1 and a second bucket 2. One end of the first bucket 1 is hinged to one end of the second bucket 2. A first flap 3 is hinged to the top of the first bucket 1, and a second flap 4 is hinged to the top of the second bucket 2. A connecting rope 12 is fixedly connected to the top of the first flap 3 and the second flap 4. A steel wire rope 5 is fixedly connected to the middle of one end of the second bucket 2. A fixing plate 6 is fixedly connected to the top of the steel wire rope 5. A hook 9 is rotatably connected inside the fixing plate 6. A hook head 10 is fixedly connected to one end of the hook 9. The middle of the connecting rope 12 is located inside the hook head 10.
[0021] In use, by pulling the connecting ring 7 upward, the connecting ring 7 will move the fixing plate 6, making the fixing plate 6 vertical. Then, the middle part of the connecting rope 12 is put into the inside of the hook head 10. The two ends of the connecting rope 12 will pull the first flap 3 and the second flap 4 respectively. Then, by continuing to pull the connecting ring 7 upward, under the gravity of the first bucket 1 and the second bucket 2, the connecting rope 12 will move the hook head 10 to the bottom side of the fixing plate 6, so that the first bucket 1 and the second bucket 2 are in the open state and placed at the bottom of the water for sampling.
[0022] Furthermore, a connecting ring 7 is provided at the top of the fixing plate 6, and a fixing shaft 8 is provided in the middle of the fixing plate 6. The fixing shaft 8 is rotatably connected to the inside of the hook 9. When the connecting rope 12 pulls the hook head 10, the hook head 10 will drive the hook 9 to rotate around the fixing shaft 8.
[0023] Furthermore, a counterweight 11 is fixedly connected to one end of the hook 9. When the first bucket 1 and the second bucket 2 are placed at the bottom of the water, the weight of the counterweight 11 will be greater than the weight of the connecting rope 12 inside the hook head 10. The counterweight 11 will drive the hook 9 to rotate, and the hook 9 will drive the hook head 10 to move upward. The connecting rope 12 will disengage from the inside of the hook head 10. Finally, by pulling the connecting ring 7, the connecting ring 7 will drive the fixing plate 6 to move upward, the fixing plate 6 will drive the wire rope 5 to move upward, and the wire rope 5 will drive the second bucket 2 to move upward. When the first bucket 1 moves upward, the second bucket 2 will drive the first bucket 1 to move upward through the hinge end. Under the action of gravity, the first bucket 1 and the second bucket 2 will approach and close together to sample the bottom soil. The clamshell sampler uses a pair of interlocking steel lobes to cut into the bottom soil after reaching the seabed. When extracting, the two lobes close to effectively grab the sample, which greatly improves the sampling success rate and reduces the time and cost wasted due to failure to obtain a sample. The closed first bucket 1 and the second bucket 2 will move upward through the steel wire rope 5. The operation is simple and convenient.
[0024] Furthermore, a fixed base 13 is fixedly connected to the top of the second bucket 2, and a rotating shaft 14 is fixedly connected to both ends of the bottom of the second flap 4. The rotating shaft 14 is rotatably connected inside the fixed base 13. When the connecting rope 12 pulls the second flap 4, the second flap 4 will drive the rotating shaft 14 at both ends of the bottom to rotate around the fixed base 13, thereby opening the top of the second bucket 2.
[0025] Working principle: By pulling the connecting ring 7 upward, the connecting ring 7 will drive the fixed plate 6 to move, making the fixed plate 6 vertical. Then, the middle part of the connecting rope 12 is looped inside the hook head 10. The two ends of the connecting rope 12 will pull the first flap 3 and the second flap 4 respectively. Then, by continuing to pull the connecting ring 7 upward, under the gravity of the first bucket 1 and the second bucket 2, the connecting rope 12 will drive the hook head 10 to move to the bottom side of the fixed plate 6, so that the first bucket 1 and the second bucket 2 are in the open state and placed at the bottom of the water for sampling.
[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
