Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ecological observation devices, specifically a synchronous sampler for pore water sediments in mangrove swamps. Background Technology
[0002] In existing technologies, sediment samplers can only collect sediments and cannot collect pore water in marshland at the same time. This means that in actual sampling work, sediments and pore water in marshland must be collected separately, which not only increases the workload in the field, but also makes it difficult to ensure the correspondence between sediments and pore water. Utility Model Content
[0003] Purpose of the utility model: To provide a synchronous sampler for pore water sediments in mangrove swamps. The combination of the mud sampler and the collection shell facilitates sediment collection, while the combination of the collection shell, rubber tube, filter and peristaltic pump enables the collection of pore water during sediment collection.
[0004] The technical solution of this utility model is as follows: a synchronous sampler for pore water sediments in mangrove swamps includes: a collection shell, a mud sampler, a rubber tube, a filter element, and a peristaltic pump.
[0005] The collecting shell is provided with a first collecting chamber and a water collecting hole, and the mud collector is provided with a second collecting chamber.
[0006] The mud sampler is inserted into the first collection chamber of the collection shell, and the second collection chamber is used to collect sediment.
[0007] The water collection port is located on the side wall of the collection shell. The filter element and the rubber tube are installed in the water collection port. The rubber tube is used to connect to the peristaltic pump, which collects pore water.
[0008] In a further embodiment, the collection shell is provided with multiple water collection holes, which are distributed from top to bottom to collect pore water at different heights.
[0009] In a further embodiment, the water collection holes are spirally distributed on the side wall of the collection shell, which can obtain pore water at different heights and directions.
[0010] In a further embodiment, the sampler further includes a hollow screw and a nut, and the filter element is a silk screen.
[0011] The hollow screw is installed at the water collection hole position on the side wall of the collection shell, and the screen and rubber tube are installed on the hollow screw by a nut.
[0012] In a further embodiment, the rubber tube is installed at the water collection hole in the first collection cavity. The rubber tube in the first collection cavity does not affect the shape of the outer wall of the collection shell, which is beneficial to the sinking of the collection shell.
[0013] In a further embodiment, the sampler also includes a plurality of first fittings.
[0014] Multiple first tubular components can be detachably connected to form a collection shell. The collection shell formed by the first tubular components facilitates the assembly of the filter element and the rubber tube when the first tubular components are separated.
[0015] In a further embodiment, the sampler also includes a plurality of second fittings.
[0016] Multiple second pipe fittings can be detachably connected to form a mud sampler. Since both the sampling shell and the mud sampler are detachable, the carrying length can be reduced, making it convenient to carry the sampler.
[0017] In a further embodiment, a plurality of the first pipe fittings are threaded together.
[0018] Multiple second pipe fittings are threaded together.
[0019] In a further embodiment, the sampler further includes a handle disposed at the top of the mud sampler; The bottom of the mud sampler and the collection shell are threaded together. Through the connection of the handle, the mud sampler and the collection shell, the collection shell can be rotated and pressed down when the texture of the mangrove experimental site is hard, which makes it easier to press the collection shell into the sediment.
[0020] In a further embodiment, the sampler further includes a mud presser, which is detachably disposed within the handle, enabling the sediment to be easily pressed out of the first collection chamber for further processing.
[0021] The beneficial effects of this utility model are: the collection shell and the collection chamber of the mud sampler enable the collection shell to leave the sediment in the second collection chamber when it is pulled out of the sediment, which facilitates the collection of sediment. Through the cooperation of the collection shell, rubber tube, filter and peristaltic pump, the peristaltic pump can be used to collect pore water when the collection shell is inserted into the sediment to collect sediment, which solves the problem that the existing collectors cannot collect sediment and pore water at the same time.

[0029] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0030] This application discloses a synchronous sampler for pore water sediments in mangrove swamps. The combination of a mud sampler and a collection shell facilitates sediment collection, while the combination of the collection shell, rubber tube, filter, and peristaltic pump enables the collection of pore water during sediment collection.
[0031] like Figure 1 The sampler shown includes: a collection shell 1, a mud sampler 2, a rubber tube 3, and a filter element 4.
[0032] The collection shell 1 is provided with a first collection chamber 13 and a water collection hole 12, and the mud collector 2 is provided with a second collection chamber 23.
[0033] The mud sampler 2 is inserted into the first collection chamber 13 of the collection shell 1, and the second collection chamber 23 is used to collect sediment.
[0034] A water collection port 12 is located on the side wall of the collection shell 1. A filter element 4 and a rubber tube 3 are installed in the water collection port 12. The sampler also includes a peristaltic pump. The rubber tube 3 is used to connect the peristaltic pump and collect pore water through the peristaltic pump.
[0035] like Figure 1 , 2 The bottom of the collection shell 1 shown in Figures 4 and 5 is a conical structure.
[0036] The collection shell 1 is provided with multiple water collection holes 12, which are distributed from top to bottom.
[0037] like Figure 1 and 2 The water collection holes 12 shown are spirally distributed on the side wall of the collection shell 1.
[0038] like Figure 3 The sampler shown also includes: a hollow screw 5 and a nut 6, and a filter element 4 is a silk screen.
[0039] Hollow screw 5 is installed at the water collection hole 12 on the side wall of the collection shell 1. The screen and rubber tube 3 are installed on the hollow screw 5 by nut 6. The screw and nut 6 fixing the rubber tube 3 is existing technology. The screw and nut 6 of different samplers can be replaced and adjusted to the appropriate model according to the size of the rubber tube 3.
[0040] like Figure 1 and 2 The rubber tube 3 shown is installed at the water collection hole 12 and is located in the first collection chamber 13.
[0041] like Figure 1 and 2 The sampler shown also includes: multiple first tubes 11, which are detachably connected to form a collection housing 1.
[0042] like Figure 1 and 2 The sampler shown also includes: multiple second pipe fittings 21, which are detachably connected to form a mud sampler 2.
[0043] Multiple first pipe fittings 11 are threaded together, and multiple second pipe fittings 21 are threaded together.
[0044] like Figure 1 The sampler shown also includes a handle 22, which is located at the top of the mud sampler 2. The handle 22 can be detachably connected to the mud sampler 2 via a threaded connection, or it can be fixedly connected to a second pipe fitting 21.
[0045] like Figure 5 The bottom of the mud sampler 2 and the collection shell 1 are threaded together.
[0046] The sampler also includes: a mud press 7, which is detachably housed within the handle, including but not limited to: Figure 6 The mud press 7 shown is detachably installed inside the handle via a snap fastener 8, and the mud press 7 can be removed from the handle by pressing the snap fastener 8.
[0047] In use, different numbers and lengths of first pipe fittings 11 and second pipe fittings 21 can be selected according to the required sampling depth to form the sampling shell 1 and the mud sampler 2. Figure 1 and 2 In the embodiment shown, the three first pipe sections 11 are 20cm, 30cm and 10cm from top to bottom, and the second pipe section 21 is matched accordingly.
[0048] Before assembling the collection shell 1, use hollow screws 5 and nuts 6 to install the screen and rubber tube 3, and place the rubber tube 3 inside the first collection chamber 13.
[0049] When encountering a relatively hard surface at the experimental location, ensure that the bottom of the collection shell 1 and the mud sampler 2 are as follows: Figure 5 The threaded connection is shown, and when the collection shell 1 is pressed down, the mud sampler 2 is rotated by the handle 22, which in turn drives the collection shell 1 to rotate during the pressing process.
[0050] As the collection shell 1 sinks, sediment enters the second collection chamber 23. When the collection shell 1 sinks to the predetermined depth, a peristaltic pump is used to collect pore water from the side of the collection shell 1.
[0051] After sampling is completed, the collection shell 1 is extracted from the sediment, the mud press 7 is extracted from the handle 22, and then the mud press 7 is used to press the sediment out of the second collector for further processing.
[0052] During the sampling process, only sediment can be collected without collecting pore water, depending on the need.
[0053] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
