Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a water sampling device. Background Art

[0002] Sampling is generally required for water quality testing. When sampling, the sample water is directly filled into the sampling bottle underwater, and then the sampling bottle is closed. However, when sampling in a field environment, the sampling personnel may not be able to smoothly reach the water's edge to fill water. For example, if the water is more than 1m below the edge, it is difficult for the sampling personnel to take samples through the sampling bottle even if they climb down. At this time, the sampling bottle can be tied with an extension rod, and then the sampling bottle is extended into the water through the extension rod for sampling. In this way, the water can be smoothly filled into the sampling bottle. In the actual operation process, the bottle mouth tube of the sampling bottle generally needs to be facing upwards and opened to allow the water to enter smoothly. However, this may cause some floating objects on the water surface to enter the sampling bottle. At the same time, the water in the sampling bottle may overturn during the lifting process, resulting in sampling failure. Therefore, the operation needs to be very careful, which is time-consuming and labor-intensive, and the efficiency cannot be improved. Utility Model Content

[0004] According to an embodiment of the utility model, a water sampling device comprises: a sampling bottle, a bottle mouth tube is provided at one end of the sampling bottle and is connected to a bottle cap that blocks the bottle mouth tube, and the other end is connected to a balancing tube, the balancing tube communicating with the inside and outside of the sampling bottle, the sampling bottle is also fixedly connected to an extension rod, the extension rod extending toward a direction away from the bottle mouth tube; a rotating rod, the rotating rod comprising a first rod section located in the sampling bottle, and a second rod section that rotates and passes through the sampling bottle, one end of the first rod section is fixedly connected to the bottle cap, and the other end is fixedly connected to the second rod section; a sleeve, the sleeve is located outside the sampling bottle, and the sleeve is also fixedly connected to the sampling bottle and surrounds the outside of the second rod section; the bottle cap comprises a bottom plate and a connecting tube fixedly connected to the bottom plate, the first rod section is fixedly connected to the bottom plate, an inner wall of the connecting tube is further provided with a first threaded section at one end close to the bottom plate, and a second threaded section is further provided at the other end, a third threaded section is provided on the outer wall of the bottle mouth tube, which respectively cooperates with the first threaded section and the second threaded section, and the connecting tube is further provided with a communicating hole located between the first threaded section and the second threaded section.

[0005] In the above embodiment, the extension rod is similar to that in the prior art, which can enable the sampling bottle to reach the water smoothly. The difference is that a rotating rod is also provided in this solution, and the bottle mouth tube and the bottle cap are located below when the sampling operation is performed. After the sampling bottle enters the water surface, the bottle cap can be partially turned open by the rotating rod so that the provided connecting hole can smoothly connect the sampling bottle and the underwater environment. Water can enter the sampling bottle through the connecting hole, and then the rotating rod is rotated to close the bottle cap again, and the sampling bottle can be taken out. In this process, floating objects on the water surface have no chance to enter the sampling bottle, and water will not be accidentally spilled. The operation is quick, which solves the problem of time-consuming, labor-intensive and low efficiency when an extension rod is needed to assist in sampling in the prior art.

[0006] Furthermore, the extension rod is fixedly connected to the positioning plate, the second rod section rotates and passes through the positioning plate, and the end of the balance tube facing away from the sampling bottle is detachably connected to the positioning plate.

[0007] Furthermore, the balancing tube is a hose and both ends are fixedly connected to a first fixed tube and a second fixed tube, a third fixed tube is fixedly connected to the sampling bottle and the first fixed tube is connected to the third fixed tube, and the second fixed tube is connected to the positioning plate.

[0008] Furthermore, a positioning sleeve is provided on the positioning plate, and the second fixing tube is threadedly connected to the positioning sleeve.

[0009] Furthermore, a rotating sleeve is fixedly connected to the positioning plate, and the second rod section rotates through the rotating sleeve.

[0010] Furthermore, a handle is fixedly connected to the end of the second rod segment facing away from the first rod segment.

[0011] Furthermore, the sleeve and the limiting plate are arranged on both sides of the positioning plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Similarly, the sampling bottle is extended into the water by the extension rod, but the connecting hole is opened and closed in the water by the rotating rod to assist the bottle cap, so that water can enter the sampling bottle smoothly, and floating objects on the water surface have no chance to enter the sampling bottle during the process, and water will not be accidentally spilled. The operation is quick, which solves the problem of time-consuming, labor-intensive and low efficiency in the prior art when the extension rod is needed to assist sampling.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] In an exemplary embodiment, Figure 1-5As shown, this embodiment provides a water sampling device, which includes: a sampling bottle 1, a bottle mouth tube 2 is provided at one end of the sampling bottle 1 and is connected to a bottle cap 3 that blocks the bottle mouth tube 2, and a balance tube 4 is connected at the other end. The balance tube 4 connects the inside and outside of the sampling bottle 1, and the sampling bottle 1 is also fixedly connected to an extension rod 5, which extends toward a side away from the bottle mouth tube 2, and the two ends of the balance tube 4 connect the inside and outside of the sampling bottle 1, so that the air pressure inside the sampling bottle 1 is the same as the external air pressure, and when the bottle cap 3 is opened, water can smoothly enter the sampling bottle 1; a rotating rod 6, which includes a rotating rod 6 located at the sampling bottle 1, and the second rod segment 8 that rotates and passes through the sampling bottle 1, one end of the first rod segment 7 is fixedly connected to the bottle cap 3, and the other end is fixedly connected to the second rod segment 8, the first rod segment 7 and the second rod segment 8 are fixed, and the second rod segment 8 rotates outside the sampling bottle 1 to drive the first rod segment 7 to rotate, so that the bottle cap 3 rotates. At this time, the sampling bottle 1 can be kept relatively motionless by holding the extension rod 5 to ensure that the bottle cap 3 can rotate smoothly relative to the bottle mouth tube 2; the sleeve 9, the sleeve 9 is partially located outside the sampling bottle 1, and the sleeve 9 is also fixedly connected to the sampling bottle 1 and surrounds the first Outside the second rod section 8, the sleeve 9 has a longer length and surrounds the outside of the second rod section 8, so that when the sampling bottle 1 is located under the water surface, the end of the sleeve 9 away from the sampling bottle 1 can be located on the water surface, which can prevent water from accidentally entering the sampling bottle 1 from the rotation point of the second rod section 8 and the sampling bottle 1, thereby preventing floating impurities from being brought in; the bottle cap 3 includes a bottom plate 11 and a connecting tube 10 fixedly connected to the bottom plate 11, the first rod section 7 is fixedly connected to the bottom plate 11, and the inner wall of the connecting tube 10 is further provided with a first threaded section at one end close to the bottom plate 11 and a second threaded section at the other end The outer wall of the bottle mouth tube 2 is provided with a third thread segment which cooperates with the first thread segment and the second thread segment respectively. The connecting cylinder 10 is further provided with a communicating hole 12 located between the first thread segment and the second thread segment. Specifically, the overall length of the third thread segment is equivalent to the distance between the two end portions of the first thread segment and the second thread segment. In this way, when the rotating rod 6 rotates, the bottle cap 3 can be rotated, so that when the communicating hole 12 is connected to the inside and outside of the sampling bottle 1, the bottle cap 3 is not completely disengaged from the bottle mouth tube 2, and water enters normally. Then, the rotating rod 6 is rotated in the opposite direction to close the bottle cap 3.

[0024] After the bottle cap 3 is closed, the sampling bottle 1 can be taken out, and floating objects on the water surface will not have the opportunity to enter the sampling bottle 1, and there will be no accidental spillage of water. The operation is quick, which solves the problem of time-consuming, labor-intensive and low efficiency in the prior art when the extension rod 5 is needed to assist in sampling.

[0025] More specifically, one end of the extension rod 5 is fixedly connected to the sampling bottle 1, and the other end is fixedly connected to a positioning plate 13. The second rod segment 8 rotates through the positioning plate 13, and the end of the balance tube 4 facing away from the sampling bottle 1 is detachably connected to the positioning plate 13. The positioning plate 13 provides a positioning basis for the rotating rod 6 and the balance tube 4, especially the balance tube 4, so that a hose material can be used to reduce the overall weight, while ensuring that the balance tube 4 is stably positioned above the water surface. The end of the rotating rod 6 can also be fixedly connected to a handle 14, that is, the end of the second rod segment 8 facing away from the first rod segment 7 is fixedly connected to the handle 14, for the operator to hold and rotate with one hand, and hold the extension rod 5 with the other hand.

[0026] like Figure 1 、 5 As shown, the main body of the balancing tube 4 can be a hose, with a first fixed tube 15 and a second fixed tube 16 fixedly connected at both ends respectively. A third fixed tube 17 is fixedly connected to the sampling bottle 1 and the first fixed tube 15 is connected to the third fixed tube 17. The first fixed tube 15 and the third fixed tube 17 can be threadedly connected. The second fixed tube 16 is connected to the positioning plate 13. More specifically, a positioning sleeve 18 is provided on the positioning plate 13, and the second fixed tube 16 is threadedly connected to the positioning sleeve 18. The positioning sleeve 18 can pass through the positioning plate 13 for connection to the second fixed tube 16, or it can be threadedly connected. In particular, when the communicating hole 12 on the bottle cap 3 is in the open and closed states, the hose (i.e., the main body of the balancing tube 4) is in an untensioned state to prevent the hose from being pulled.

[0027] In more detail, the positioning plate 13 is further fixedly connected with a rotating sleeve 19, and the second rod segment 8 rotates through the rotating sleeve 19. The second rod segment 8 can also be fixedly connected with a limiting plate 20, and the limiting plate 20 and the positioning plate 13 are respectively arranged on both sides of the rotating sleeve 19, and the sleeve 9 and the limiting plate 20 are respectively arranged on both sides of the positioning plate 13. The rotating sleeve 19 is for the second rod segment 8 to rotate through, so that the handle 14 can be arranged on the other side of the positioning plate 13, which is convenient for operation. At the same time, when the limiting plate 20 and the rotating sleeve 19 abut against each other, the bottle cap 3 can be completely disengaged from the bottle mouth tube 2, or it can be partially disengaged so that the communicating hole 12 is in an open state, so that the rotating rod 6 can have an upward lifting support. At the same time, the sleeve 9 and the second rod segment 8 can also be rotatably matched, and the rotating sleeve 19 and the second rod segment 8 can also be rotatably matched. In this way, even if the bottle cap 3 is completely disengaged, it can be smoothly and smoothly covered with the bottle mouth tube 2 again under the rotation guide of the sleeve 9 and the rotating sleeve 19.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
