Description

Technical Field

[0001] This utility model belongs to the field of marine water detection technology, specifically relating to a deep water sampling device for marine detection. Background Technology

[0002] Seawater quality testing aims to assess the health of the marine environment, including parameters such as water temperature, salinity, pH, dissolved oxygen, turbidity, and nutrients. Water quality testing in deep-sea environments typically requires the use of sampling devices to collect water samples, which play a crucial role in oceanographic research, environmental monitoring, and water quality assessment.

[0003] A Chinese utility model patent, CN216645984U, discloses a water sampling device for marine ranching testing. This utility model incorporates a lifting component that allows the sampling tube to rise and fall, enabling it to extend into water at different depths. This facilitates water sampling at various depths, overcoming the limitation of existing water sampling devices that cannot sample water at different depths. Furthermore, it can seal the inlet pipe, isolating the sample and improving the accuracy of water sample collection, thereby enhancing testing precision.

[0004] However, existing sampling devices use a winding rope to raise the sampling cylinder during sampling. However, the winding rope cannot be wound in an orderly manner, and the wound rope is prone to tangling and knotting, which affects the normal lowering and retrieval of the sampler, making subsequent sampling work more difficult and time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a deep-water sampling device for marine testing, which can orderly wind up the rope, prevent the rope from getting tangled and knotted, make the lowering and retrieval of the sampler smoother, and improve the overall work efficiency.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A deep-water sampling device for marine testing includes a sampling frame, a winding roller, a winding rope, a sampler, and a servo motor. One end of the winding roller is connected to the inner side of the sampler via a bearing, and the other end of the winding roller extends to the outer side of the sampling frame. The winding rope is wound around the surface of the winding roller, and one end of the winding rope is connected to the inner side of the sampling frame. The sampler is connected to the other end of the winding rope. The servo motor is fixedly mounted on the outer side of the sampling frame, and one output end of the servo motor is fixedly connected to the end of the winding roller. A sorting mechanism is provided on the inner side of the sampling frame. The sorting mechanism includes a rotating column, a transmission wheel, a pulley, a transmission belt, a track groove, and a limiter. The sampling frame consists of a positioning rod, a rope loop, and a sliding column. One end of the rotating column is connected to the inner side of the sampling frame via a bearing, and the other end of the rotating column extends to the outer side of the sampling frame. The drive wheel is fixedly sleeved on the surface of the take-up roller and located on the outer side of the sampling frame. The pulley is sleeved on the surface of the rotating column and located on the outer side of the sampling frame. The transmission belt is respectively sleeved in the grooves of the drive wheel and the pulley. The track groove is formed on the surface of the rotating column. The positioning rod is fixedly connected to the inner side of the sampling frame. The rope loop is slidably connected to the surface of the positioning rod. The take-up rope passes through the inner side of the rope loop. The sliding column is fixedly connected to the rear side of the rope loop and slidably connected inside the track groove.

[0008] Preferably, the sampler has water inlets on the front and rear sides of its surface, and a filter plate is installed inside the sampler.

[0009] Preferably, the bottom of the sampler is equipped with an iron weight, which is cylindrical in shape and made of stainless steel.

[0010] Preferably, the front side of the sampler is connected to a liquid outlet tube, and a rubber stopper is provided inside the liquid outlet tube.

[0011] Preferably, a support plate is fixedly connected to the outer side of the sampling frame, and the servo motor is mounted on the top of the support plate.

[0012] Preferably, the sampler is conical in shape and made of titanium alloy.

[0013] The technical effects achieved by this utility model are as follows:

[0014] In this invention, after seawater sampling, a servo motor can be activated. The servo motor drives the take-up roller to rotate, which winds the take-up rope onto its surface. Simultaneously, the rotation of the take-up roller drives the transmission wheel to rotate, which in turn drives the pulley to rotate via the transmission belt. The pulley's rotation, in turn, drives the rotating column to rotate, causing the sliding column to slide along the track groove. Under the guidance and limitation of the limit rod, the rope loop and the sliding column are further limited, allowing them to move parallel to the limit rod. As the rope loop moves, it drives the take-up rope to wind orderly around the surface of the take-up roller along the parallel movement track, preventing the take-up rope from tangling and knotting during the winding process, which would hinder the successful retrieval and sampling of the sampler.

[0020] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figures 1-3As shown, a deep-water sampling device for marine testing includes a sampling frame 1, a winding roller 101, a winding rope 102, a sampler 103, and a servo motor 104. One end of the winding roller 101 is connected to the inner side of the sampler 103 via a bearing, and the other end of the winding roller 101 extends to the outer side of the sampling frame 1. The winding rope 102 is wound around the surface of the winding roller 101, and one end of the winding rope 102 is connected to the inner side of the sampling frame 1. The sampler 103 is connected to the winding rope 102. At the other end of 2, a servo motor 104 is fixedly installed on the outside of the sampling frame 1. The output end of one side of the servo motor 104 is fixedly connected to the end of the take-up roller 101. A sorting mechanism is provided on the inner side of the sampling frame 1. The sorting mechanism includes a rotating column 201, a transmission wheel 202, a pulley 203, a transmission belt 204, a track groove 205, a limit rod 206, a rope ring 207, and a sliding column 208. One end of the rotating column 201 is connected to the inner side of the sampling frame 1 through a bearing. The other end of the column 201 extends to the outside of the sampling frame 1. The drive wheel 202 is fixedly sleeved on the surface of the take-up roller 101 and located on the outside of the sampling frame 1. The pulley 203 is sleeved on the surface of the rotating column 201 and located on the outside of the sampling frame 1. The transmission belt 204 is respectively sleeved in the grooves of the drive wheel 202 and the pulley 203. The track groove 205 is opened on the surface of the rotating column 201. The limiting rod 206 is fixedly connected to the inside of the sampling frame 1. The rope ring 207 is slidably connected to the surface of the limiting rod 206. The take-up rope 102 passes through the inside of the rope ring 207. The sliding column 208 is fixedly connected to the rear side of the rope ring 207. The sliding column 208 is slidably connected to the inside of the track groove 205. With the cooperation of the sorting mechanism, the take-up rope 102 can be neatly and orderly wound around the surface of the take-up roller 101 during sampling, effectively avoiding the entanglement or knotting of the take-up rope 102 during the recycling process, reducing device failures and improving work efficiency.

[0022] like Figure 3 As shown, the sampler 103 has inlets 301 on the front and rear sides. A filter plate 302 is installed inside the sampler 103. During sampling, seawater can enter the sampler 103 through the inlets 301 and be filtered by the filter plate 302. Impurities in the seawater can be filtered onto the filter plate 302. The filtered seawater will pass through the filter plate 302 and be collected inside the sampler 103. By filtering the seawater before collecting the sample, solid suspended matter, particles, microorganisms and organic matter can be removed, ensuring that the collected seawater sample is purer and more reliable.

[0023] like Figure 3As shown, a weight 303 is installed at the bottom of the sampler 103. The weight 303 is cylindrical in shape and made of stainless steel. The weight of the weight 303 can increase the sinking speed of the sampler 103, helping it to reach the required sampling depth quickly and stably. During the sampling process, especially in deep sea or waters with strong currents, the weight 303 helps to ensure that the sampler 103 can accurately reach the predetermined depth and position, avoiding errors or sample contamination.

[0024] like Figure 3 As shown, the front of the sampler 103 is connected to the liquid outlet pipe 304. The inside of the liquid outlet pipe 304 is equipped with a rubber stopper. By setting the liquid outlet pipe 304, it is convenient to discharge the sample collected inside the sampler 103 for sampling. The rubber stopper can prevent the seawater sample inside from flowing out through the liquid outlet pipe 304 when the sampler 103 is lifted and wound up, resulting in insufficient water volume for sampling.

[0025] like Figure 1 and Figure 2 As shown, a support plate 4 is fixedly connected to the outer side of the sampling frame 1. The servo motor 104 is installed on the top of the support plate 4. The support plate 4 can stably support the servo motor 104, ensuring that the servo motor 104 is stable and does not shift during operation, and avoiding the shaking caused by vibration when the servo motor 104 is working, thus reducing the displacement and instability factors of the servo motor 104.

[0026] like Figure 1 and Figure 3 As shown, the sampler 103 is conical in shape and made of titanium alloy. The conical design helps the sampler 103 to quickly and stably enter the target layer in the water, reducing the impact of water flow or external disturbances on sampling. Its streamlined shape makes the sampler 103 move more smoothly in the water, avoiding greater resistance or vibration, thereby improving the accuracy and precision of sampling. Titanium alloy has excellent corrosion resistance and oxidation resistance, making it particularly suitable for use in seawater with high salt concentration. The low specific gravity of titanium alloy reduces the overall weight of the seawater sampler 103, making it suitable for deep-sea and high-pressure environments and giving it a long service life.

[0027] The working principle of this utility model is as follows: After seawater sampling, the servo motor 104 can be activated. The operation of the servo motor 104 will drive the take-up roller 101 to rotate. When the take-up roller 101 rotates, it can wind the take-up rope 102 onto the surface of the take-up roller 101. The rotation of the take-up roller 101 can also drive the transmission wheel 202 to rotate. The rotation of the transmission wheel can drive the pulley 203 to rotate through the transmission belt 204. The rotation of the pulley 203 will simultaneously drive the rotating column 201 to rotate. The rotation of the rotating column 201 will cause the sliding... The column 208 slides along the track groove 205, and under the guidance and limitation of the limiting rod 206, it can assist in limiting the rope ring 207 and the sliding column 208, so that the sliding column 208 and the rope ring 207 move parallel to the limiting rod 206. When the rope ring 207 moves, it can drive the winding rope 102 to wind orderly around the surface of the winding roller 101 along the parallel movement track, so as to avoid the winding rope 102 from getting tangled and knotted during the winding process, which would prevent the sampler 103 from being able to recycle and sample smoothly.

[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
