[0002] With the increasing importance of water resource management and environmental protection, river sediment sampling plays a key role in hydrological research, environmental monitoring and ecological assessment. Accurate sediment sampling is essential for assessing the sediment load, pollutant migration and ecosystem health of rivers. However, traditional samplers have exposed many problems in actual use, which seriously affect the representativeness of sampling results and the accuracy of data.

[0003] Traditional river sediment samplers mainly include grab samplers, cylinder samplers and bottle samplers. Although these samplers meet the basic needs of sediment collection to a certain extent, they still have many shortcomings in actual operation. For example, in a turbulent water environment, the grab sampler is easy to shake with the water flow due to its large cross-section, and has poor stability. The cylinder sampler has the problems of limited sampling range and insufficient sampling volume, and the bottle sampler has poor collection effect on sediment and sediment, especially in waters with low sediment concentration, and the sampling efficiency is low. Therefore, in view of the above problems, a conical sediment sampler is designed to better meet the actual use needs. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-Figure 3 The utility model provides a technical solution: a conical mud sampler, including a gravity plate 1 and a clamping jaw 2, a clamping jaw 2 is arranged on the lower side of the clamping jaw 2, a mud guide tube 4 is fixed on the gravity plate 1, the mud guide tube 4 is connected with the gravity plate 1, a hydraulic rod 5 is also fixed on the gravity plate 1, a movable plate 6 is fixed on the output end of the hydraulic rod 5, the movable plate 6 and the mud guide tube 4 are slidably connected, a threaded joint 401 is fixed on the mud guide tube 4, and the threaded joint 401 is connected to the sampler 7 through a thread.

[0018] A lifting ear 101 with an arc structure is fixed on the gravity plate 1, and there are four lifting ears 101 distributed at equal angles with respect to the center of the gravity plate 1; there are four clamping jaws 2 distributed at equal angles with respect to the center of the gravity plate 1, and the four clamping jaws 2 cooperate to form a conical structure, and a connecting rod 201 is fixed on the clamping jaw 2, and the connecting rod 201 is rotatably connected to the gravity plate 1; one end of the rotating rod 3 is rotatably connected to the connecting rod 201, and the other end of the rotating rod 3 is rotatably connected to the movable plate 6; a GPS locator 601 is fixed on the movable plate 6, and the model of the GPS locator 601 is u-blox NEO-M8N GPS module; a piston rod 701 is slidably connected to the sampler 7, and a piston head 702 is fixed to the lower end of the piston rod 701, and the piston head 702 is slidably connected to the sampler 7 and the mud guide tube 4;

[0019] When using the cone-shaped mud sampler, Figure 1-Figure 3As shown, by threading the sampler 7 and the threaded connector 401, the piston head 702 slides into the mud guide tube 4 to seal the lower end of the mud guide tube 4, and then the wire rope is fixed to the lifting ear 101, and the entire device can be sunk underwater for sampling by releasing the wire rope. During the sinking process of the device, the four clamping jaws 2 are in a closed conical state. The conical structure composed of the four clamping jaws 2 can reduce the impact of water flow impact on the device, thereby ensuring the stability of the device. In actual operation, sampling positioning can be achieved through the GPS locator 601, which is convenient for recording the location data of the sampling point. When the device is close to the bottom of the water, the hydraulic rod 5 is controlled to extend, thereby driving the movable plate 6 to move up. The sliding guiding effect between the movable plate 6 and the mud guide tube 4 can ensure the stability of the movement of the movable plate 6. When the movable plate 6 moves, the transmission effect of the rotating rod 3 and the rotation effect between the connecting rod 201 and the gravity plate 1 can be cooperated, so that the clamping jaws 2 can be stretched under force. Open, and then cooperate with the gravity of the gravity plate 1 and the pointed structure at the end of the clamping jaw 2, the clamping jaw 2 can be inserted into the bottom mud, and when the clamping jaw 2 is unfolded, the piston head 702 blocks the lower end of the mud guide tube 4, which can prevent water from entering the mud guide tube 4, and can prevent the sample from containing more water in the later period. Then, by controlling the hydraulic rod 5 to contract, the clamping jaw 2 can be closed. During the closing process of the clamping jaw 2, water can be distributed outward through the gap between the clamping jaws 2, and the mud and sand captured by the clamping jaw 2 can be forced to move upward due to the reduction of the internal space after the clamping jaw 2 contracts. Under the force of the mud and sand, the piston head 702 can be moved upward, and with the action of the mud guide tube 4, the mud and sand can be stored in the sampler 7, thereby completing the sampling operation, and can effectively ensure the integrity and purity of the sample. When testing the sample in the later period, it is only necessary to separate the sampler 7 from the mud guide tube 4, and the sample in the sampler 7 can be discharged by pressing the piston rod 701, so as to facilitate the sample testing. This is the working principle of the conical mud sampler.
