In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0031] like Figures 1 to 9 As shown, an anchor type mud sampler comprises an anchor column 1, wherein a sampling channel 3 penetrating the anchor column 1 is provided in the anchor column 1;
[0032] The upper half of the anchor column 1 is threaded with a locking screw 7, the upper end of the locking screw 7 is provided with a connector 8, the connector 8 is connected to the lower end of the anchor rope 2, the lower end of the locking screw 7 is provided with a stop block 9, the stop block 9 is provided with a limiting opening 10, and a bolt 11 passes through the anchor column 1 and the limiting opening 10 to limit the stop block 9;
[0033] The lower half of the anchor column 1 is provided with four anchor tubes 5, each of which is arranged in a circular array along the center line of the anchor column 1, and the output end of each anchor tube 5 is connected to the sampling channel 3, and the angle θ between the anchor column 1 and the anchor tube 5 is 45°;
[0034] The lower end of the anchor column 1 is detachably provided with a collecting bag 12, and the collecting bag 12 is communicated with the sampling channel 3. In the present invention, the collecting bag 12 is a nylon bag that is permeable to water but not permeable to mud.
[0035] Connection unit 20 (Embodiment 1)
[0036] The anchor column 1 is detachably connected to the collection bag 12 via a connecting unit 20;
[0037] The connecting unit 20 includes a positioning ring 22 sleeved on the lower half of the anchor column 1, and a connecting ring 23 is detachably provided at the lower end of the positioning ring 22 (see Figure 1 and Figure 2 ), the collecting bag 12 is arranged on the connecting ring 23. In this way, the collecting bag 12 and the connecting ring 23 are arranged together, and sampling is performed after the connecting ring 12 is disassembled.
[0038] Connection unit 20 (Embodiment 2)
[0039] The anchor column 1 is detachably connected to the collection bag 12 via a connecting unit 20;
[0040] The connecting unit 20 includes a positioning ring 22 sleeved on the lower half of the anchor column 1, and a circle of grooves 26 are formed around the outer edge of the positioning ring 22 (see Figure 7 ), the upper end of the collecting bag 12 is located in the card slot 26 and is positioned by the clamp 27. Compared with the connecting unit 20 in the first embodiment, the collecting bag 12 of this structure is provided separately, and the collecting bag 12 is no longer limited by the clamp 27, so the collecting bag 12 can be removed separately, so when the collecting bag needs to be replaced, only the collecting bag 12 needs to be replaced separately, and the replacement of the collecting bag is more convenient and the cost is lower.
[0041] The above two methods are two ways to fix the collecting bag 12. However, in actual use, the collecting bag 12 is not limited to the above two methods for detachable fixation. Any structure in the prior art that can achieve detachable fixation of the collecting bag 12 can also be used. No specific limitation is made on the method of the collecting bag 12 and the anchor column 1.
[0042] The connector 8 is provided with an anchor rope connection hole 28. By providing the connection hole 28, the anchor rope 2 is convenient to be detachably connected to the connector 8.
[0043] The anchor pipe 5 includes a connecting section 51 and a sampling section 52 . The input end of the sampling section 52 is provided with a sleeve 53 . The sampling section 52 is detachably connected to the input end of the connecting section 51 through the sleeve 53 . The output end of the connecting section 51 is connected to the anchor column 1 .
[0044] By configuring the anchor pipe 5 to be divided into a connecting section 51 and a sampling section 52 , it is convenient to clean the interior of the anchor pipe 5 .
[0045] The input end of the sampling section 52 has an elliptical inclined surface 55. To ensure that the anchor (sampling section 52) can smoothly enter the sediment, the end of the anchor is cut to a point (the inclined surface 55 is formed after the cutting), so as to facilitate sampling.
[0046] The input end of the sampling section 52 is sleeved with a protective sleeve 56. When not in use, the protective sleeve 56 is sleeved on the sampling section 52 to prevent the inclined surface 55 from being exposed, thereby further improving safety.
[0047] The sampling section 52 is sleeved with a limiting ring 58, and the inner end of the protective sleeve 56 is fitted with the limiting ring 58. The limiting ring 58 prevents the inclined surface 55 from contacting the inner side of the protective sleeve 56, thereby preventing the inclined surface 55 from directly contacting the protective sleeve 56 for a long time and damaging the protective sleeve 56.
[0048] The existing structure has low sampling efficiency when the water level is deep (>10 meters) and the flow rate is high.
[0049] The optimal working principle of the utility model is as follows:
[0050] When working, the end of the anchor rope 2 is fixed on a sampling boat (not shown in the figure), and the device is thrown into the water until it sinks to the bottom of the water. The sampling boat is started and towed for a distance, and sampling is performed through the anchor pipe 5. The sample (sediment) enters the collection bag 12 through the anchor pipe 5. After the sampling is completed, the device is lifted out of the water by manpower or a winch to take out the sediment.
[0051] As a further preference, by making the anchor column 1, the locking screw 7 and the connecting head 8 detachable, it is not only convenient to clean the interior of the anchor column 1, but also more convenient to replace individual components, thereby reducing the cost of use. At the same time, by providing the bolt 11, the locking screw 7 and the anchor column 1 can be effectively prevented from falling off after the structure sinks to the bottom of the water, thereby improving the firmness of the overall structure.
[0052] In the utility model, the anchor column 1 and the anchor pipe 5 are both made of hollow stainless steel pipes, the anchor column 1 has an inner diameter of 40 mm and a length of 50 cm, and the anchor pipe 5 has an inner diameter of 32 mm and a length of 30 cm. The utility model is more suitable for collecting deep water and flowing water.
[0053] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
