[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] like Figures 1-6 As shown, the present invention provides a deepwater handheld sampler comprising: a telescopic tube 1, a hose 2, and a water pumping device. The upper end of the telescopic tube 1 is connected to one end of the hose 2 via a detachable connecting assembly. The interior of the telescopic tube 1 communicates with the interior of the hose 2, and the other end of the hose 2 is connected to the output end of the water pumping device. A valve 3 is provided on the hose 2. The present invention utilizes the telescopic tube 1 to extend into the water, and the hose 2 to integrally connect the telescopic tube 1 and the water pumping device, thereby extracting water samples. The telescopic tube 1 is adjustable in length, allowing for extraction of water samples at different depths. Furthermore, the connecting assembly between the hose 2 and the telescopic tube 1 utilizes conventional technology (e.g., a clamp, connector, etc., used in the prior art). This detachable connecting assembly facilitates connection and disconnection between the hose 2 and the telescopic tube 1, making the entire device easier to store and carry. Furthermore, the water pump (not shown) used in the present invention can utilize conventional water pumps, etc.

[0025] like Figure 2-Figure 4As shown, the telescopic tube 1 in the present application includes a fixed tube 10, a sleeve 11, a telescopic hose 12 and an adjusting tube 13; the sleeve 11 is a hollow structure, the sleeve 11 is vertically arranged, the sleeve 11 and the fixed tube 10 are coaxially arranged, the lower end of the fixed tube 10 extends into the top of the sleeve 11, and the lower end of the fixed tube 10 is rotatably connected to the top of the sleeve 11; wherein the top of the sleeve 11 is fixedly provided with a rotating shaft 110 rotatably connected to the lower end of the fixed tube 10 (the rotation connection here adopts a limitable rotation connection method in the prior art, that is, the fixed tube 10 and the sleeve 11 can rotate with each other, but cannot produce axial displacement). In addition, a telescopic hose 12 is disposed axially within the sleeve 11, with the lower end of the fixed tube 10 fixedly connected to the upper end of the telescopic hose 12. An adjusting tube 13 is coaxially disposed within the sleeve 11 and below the telescopic hose 12. The upper end of the adjusting tube 13 is fixedly connected to the lower end of the telescopic hose 12, and the lower end of the adjusting tube 13 extends to the exterior of the sleeve 11. The outer wall of the adjusting tube 13 is threadedly connected to the lower end of the sleeve 11, wherein the outer wall of the adjusting tube 13 is provided with corresponding threads, and a threaded barrel 111 is fixedly provided at the bottom of the sleeve 11 and threadedly connected to the outer wall of the adjusting tube 13. The telescopic hose 12 in this application adopts a telescopic tube known in the prior art (i.e., a telescopic tube or telescopic joint commonly found on the market).

[0026] In the present application, the length of the telescopic tube 1 is adjustable; when adjusting, the portion of the adjusting tube 13 located outside the sleeve 11 can be held by hand, and then the sleeve 11 is rotated. Since the bottom of the sleeve 11 is threadedly connected to the adjusting tube 13, and the sleeve 11 is rotatably connected to the fixed tube 10, when the sleeve 11 is rotated, only the sleeve 11 rotates, while the fixed tube 10, the telescopic hose 2 and the adjusting tube 13 do not rotate; and when the sleeve 11 is rotated, the portion of the adjusting tube 13 extending from the sleeve 11 becomes longer and longer, as shown in FIG. Figure 5 As shown, the adjustment tube 13 is extended from the sleeve 11, and the telescopic hose 12 is continuously extended. When the adjustment tube 13 is retracted into the sleeve 11, the telescopic hose 12 is automatically shortened during the retraction of the adjustment tube 13.

[0027] It is also worth noting that in this application, the upper end of the regulating tube 13 is provided with an annular card 130, such as Figure 3 As shown, the outer diameter of the card 130 is smaller than the inner diameter of the sleeve 11, and the outer diameter of the card 130 is larger than the inner diameter of the threaded barrel 111. The provision of the card 130 can provide a certain limit between the sleeve 11 and the adjusting tube 13, preventing the adjusting tube 13 from being completely dislodged from the sleeve 11 due to excessive rotation of the sleeve 11. In other words, when the card 130 of the adjusting tube 13 is engaged with the upper end of the threaded barrel 111, the maximum length to which the adjusting tube 13 can extend from the sleeve 11 is reached.

[0028] In addition, for the convenience of personnel to operate well when taking water samples, a handheld portion 14 is provided at the upper end of the outer wall of the fixed pipe 10. The personnel can hold the handheld portion 14 and place the telescopic tube 1 in the water.

[0029] In addition, in the present application, a first scale bar 100 is provided on the outer wall of the fixed tube 10 along its axial direction, and the first scale bar 100 extends from the top of the fixed tube 10 to the top of the sleeve 11; a second scale bar 112 is provided on the outer wall of the sleeve 11 along its axial direction, and the second scale bar 112 extends from the top of the sleeve 11 to the bottom of the sleeve 11. The lengths of the fixed tube 10 and the sleeve 11 are both fixed, and the provision of the first scale bar 100 and the second scale bar 112 is only convenient for personnel to check the fixed length of the top of the fixed tube 10 from the bottom of the sleeve 11. When the fixed length meets the requirements of the personnel for taking water samples, there is no need to adjust the length of the adjusting tube 13 in the present application, and the water sample of the corresponding depth can be extracted by referring to the first scale bar 100 and the second scale bar 112. When the fixed length cannot meet the requirements of the personnel for taking water samples, the length of the adjusting tube 13 extending from the sleeve 11 can be extended to adjust the length of the entire telescopic tube 1. In order to facilitate viewing the length of the entire telescopic tube 1, a third scale bar 15 is slidably provided on the outer wall of the sleeve 11; Figure 4 As shown, a long groove 113 is recessed along the axial direction of the outer wall of the sleeve 11, and the bottom of the long groove 113 extends to the bottom of the sleeve 11; the third scale bar 15 is slidably arranged in the long groove 113 along the axial direction of the sleeve 11, and the 0 scale line in the third scale bar 15 is located at the bottom of the third scale bar 15; a slider 150 is provided at the top of the third scale bar 15, and sliding grooves 114 corresponding to the slider 150 are provided on the side walls on both sides of the long groove 113. After the adjustment tube 13 is adjusted, the third scale bar 15 can be pulled out to measure the extended length of the adjustment tube 13, as shown in FIG. Figure 5 As shown, the length plus the length of the first scale bar 100 and the second scale bar 112 is the length of the entire telescopic tube 1.

[0030] In addition, Figure 5 and Figure 6 As shown, the lower end of the regulating tube 13 in this application is also provided with a filter portion, which can filter out larger impurities to prevent the impurities from clogging the telescopic tube during the pumping process. Figure 6As shown, the filter unit includes a connecting tube 18 and a filter screen 19. The connecting tube 18 is sleeved on the bottom of the regulating tube 13, and the filter screen 19 is located at the bottom of the connecting tube 18. Specifically, the inner wall of the connecting tube 18 is provided with a mating thread, and the connecting tube 18 is threadedly connected to the lower end of the regulating tube 13; the lower end of the connecting tube 18 is provided with an annular boss 180, and the center of the annular boss 180 is provided with an opening 181. The filter screen is located above the annular boss 180 and is engaged with the annular boss 180. The outer diameter of the filter screen 19 is greater than or equal to the outer diameter of the regulating tube 13. Therefore, after the connecting tube 18 and the regulating tube 13 are rotated and tightened together, the bottom end of the regulating tube 13 can press the periphery of the upper surface of the filter screen 19, while the lower surface of the filter screen 19 is engaged by the annular boss 180, thereby limiting the position of the filter screen 19.
