Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sampling equipment, and more specifically to a seabed mud sampling device. Background Art
[0002] Existing seabed mud sampling devices often have difficulty ensuring the complete sealing of the sampling container in complex seabed environments, especially under conditions of high pressure and strong water flow. Due to the complex seabed topography and drastic pressure changes, the sampling device is easily interfered with by external factors during operation, resulting in the sealing of the sampling container being affected. This poor sealing often leads to partial leakage of the collected mud during the sample's ascent to the sea surface, making it impossible to ensure the integrity of the sample, which in turn affects the accuracy of the experimental data. It also increases the workload and cost of repeated sampling, making it difficult to ensure the collection of sufficient and representative mud samples. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a seabed mud sampling device to solve the problems existing in the above-mentioned background technology.
[0004] The utility model provides the following technical solutions: it includes a sampler body, two lifting steel ropes are fixedly installed on the top of the sampler body, a telescopic rod is fixedly installed on the internal top of the sampler body, a corrugated waterproof pipe is installed on the sealing sleeve of the telescopic rod, a waterproof motor is fixedly installed on the internal bottom end of the telescopic rod, a sampling electric drill is fixedly installed on the bottom end of the waterproof motor, a sealing ring is fixedly installed on the bottom end of the outer surface of the telescopic rod, a reinforced sealing gasket is fixedly installed on the inner wall of the sampler body, a support plate is fixedly installed on the bottom end of the outer surface of the sampler body, the support plate is annular, and a plurality of counterweights are evenly fixedly installed inside the support plate. When in use, the sampler body and the support plate are sunk into the sea water together by using the lifting steel rope and gradually approaching the seabed. In the initial state, the telescopic rod is shortened and the sampling electric drill is located inside the sampler body. When it reaches the seabed and needs to sample silt, the telescopic rod is extended downward. The telescopic rod will maintain its waterproof function under the action of the corrugated waterproof tube. The telescopic rod is extended, driving the sampling electric drill to extend into the seabed soil on the seabed. At this time, the bottom end of the sampler body is opened, and the sampling electric drill is started. The sampling electric drill will continue to drill holes on the seabed and generate upward water flow. These water flows will send the silt drilled by the sampling electric drill into the sampler body. After sampling is completed, the telescopic rod retracts, and the sealing ring and the reinforced sealing gasket are in close contact to prevent water leakage and sealing failure. In actual use, it effectively solves the problem that the existing seabed silt sampling device is often difficult to ensure the complete sealing of the sampling container in a complex seabed environment, which causes the collected sludge to leak easily during the rising process, affecting the integrity of the sample and making it difficult to collect a sufficient amount of sludge.
[0005] Furthermore, the support plate is fixedly mounted with multiple burrowing stop cones, each with a conical bottom end and constructed from solid stainless steel. During use, these stop cones stabilize the sampler's position on the seabed, ensuring close contact with the seabed and preventing sampling errors caused by the complex seabed environment. The solid stainless steel construction of the stop cones ensures the device's strength and durability.
[0006] Furthermore, a reinforced outer shell is fixedly mounted on the outer surface of the sampler body, and the main body of the reinforced outer shell is made of titanium alloy. When in use, the reinforced outer shell can effectively prevent damage to the device caused by high water pressure, thereby enhancing the pressure resistance and life of the device.
[0007] Furthermore, the interior of the lifting steel ropes is a hollow structure, and a control cable is installed inside the lifting steel ropes. The control cables extend through the interior of the lifting steel ropes to the interior of the sampler body. Water pressure sensors are fixedly installed on both sides of the sampler body, and the water pressure sensors are electrically connected to the control cables inside the sampler body. When in use, the hollow structure design of the lifting steel ropes not only reduces the weight of the equipment, but also enables automatic control and data monitoring of the water pressure sensors through the internal control cables, improving the convenience of operation.
[0008] Furthermore, outlet valves are installed at the bottom ends of both sides of the sampler body, and sludge filter barrels are sealed and fixedly mounted on each of the outlet valves. The sludge filter barrels are internally installed with multiple layers of screens. During use, the outlet valves and sludge filter barrels installed at the bottom ends of the sampler body can effectively remove seawater absorbed during the sampling process, retaining only the sludge sample, thereby improving the sample purity and accuracy of the experimental sample.
[0009] Furthermore, the main body material of the sampler body is aluminum alloy metal, and the main body material of the support plate is solid stainless steel.
[0010] The technical effects and advantages of this utility model are:
[0011] 1. The utility model uses a sampler body, a lifting steel rope, a telescopic rod, a sampling electric drill, a sealing ring, and a support plate to effectively solve the problem that existing seabed mud sampling devices often find it difficult to ensure the complete sealing of the sampling container in a complex seabed environment, resulting in the collected sludge easily leaking during the rising process, affecting the integrity of the sample and making it difficult to collect a sufficient amount of sludge.
[0012] 2. The utility model uses the burying limit cone. When in use, the multiple burying limit cones on the support plate can stabilize the position of the sampler body on the seabed, so that the sampler body and the seabed are in close contact, preventing sampling errors caused by the complex environment of the seabed. The solid stainless steel material of the burying limit cone ensures the strength and durability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Working principle: When in use, the lifting steel rope 110 is used to sink the sampler body 100 and the support plate 114 into the sea water together, and gradually approach the seabed. In the initial state, the telescopic rod 111 is shortened, and the sampling electric drill 112 is located inside the sampler body 100.
