Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a water sample collection mechanism. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] To understand the vertical distribution characteristics of water quality, it is necessary to collect water samples at different depths of the water body for water quality testing. Most current water sampling devices are operated manually, by attaching the sampler to a rope and placing it into the water body at a set depth. This not only makes it difficult to collect water samples close to the center of the water body, but also makes it difficult to retrieve the rope due to the complex water environment and the influence of debris at the bottom of the water body. As a result, the sampling efficiency is low and the adaptability is poor. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a water sampling mechanism that can efficiently collect water samples from various locations within a water body.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a water sample sampling mechanism, comprising:

[0006] Remote-controlled boat, used to travel to various sampling points in the water;

[0007] The pump assembly, mounted on the remotely controlled vessel, is used to pump and transport water samples.

[0008] The telescopic tube assembly has one end connected to the liquid inlet end of the pump suction assembly and the other end inserted into the water body to change the height at which the pump suction assembly draws water samples.

[0009] The telescopic control component, installed on the remote-controlled boat, is used to control the telescopic length of the telescopic tube assembly.

[0010] Furthermore, the telescopic tube assembly includes at least two sleeves that are nested together and can move along the axial direction. One of the sleeves is connected to the liquid inlet end of the pump suction assembly, and the sleeve is provided with an anti-detachment ring that is inserted into the adjacent sleeve. Correspondingly, a sliding groove is provided in the sleeve for the anti-detachment ring to move along the axial direction.

[0011] Furthermore, the telescopic control assembly includes a winding motor and a winding roller disposed at the output end of the winding motor. A pull rope is detachably disposed on the winding roller, and the end of the pull rope away from the winding roller is fixedly connected to the outermost sleeve of the telescopic tube assembly.

[0012] Furthermore, the bottom end of the outermost sleeve is provided with an annular counterweight block, and a filter screen is embedded in the annular counterweight block. The bottom ends of the other sleeves are provided with multiple pins corresponding to the filter holes of the filter screen. When the telescopic tube assembly is at its shortest length, each pin is inserted into the filter hole of the filter screen.

[0013] Furthermore, the pump suction assembly is provided with a liquid outlet component at the liquid outlet end, which can change the liquid outlet position;

[0014] The liquid outlet assembly includes a liquid outlet pipe rotatably disposed at the liquid outlet end of the pump suction assembly. The liquid outlet pipe is inverted U-shape. A driven gear capable of rotating with the liquid outlet pipe is disposed on the liquid outlet pipe. The liquid outlet assembly also includes an angle adjustment motor and a driving gear disposed at the output end of the angle adjustment motor. The driven gear and the driving gear mesh with each other.

[0015] The beneficial effects of this utility model are reflected in:

[0016] This invention involves placing a remote-controlled boat in the water body to be sampled, maneuvering the boat to the sampling point, and then, according to the required sampling height at that point, controlling the telescopic control component to change the telescopic length of the telescopic tube assembly, causing the telescopic tube assembly to extend and retract to the corresponding water layer height. Then, the pump suction component can be used to draw water samples from that water layer for discharge. By receiving the water sample at the outlet end of the pump suction component, the water sample collection is completed. The entire sampling process is not easily limited by the sampling point, achieving the goal of efficiently collecting water samples from various locations in the water body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-3 This utility model discloses a water sample sampling mechanism, comprising:

[0024] Remote-controlled boat 1, used to travel to various sampling points in the water;

[0025] Pump suction assembly 2, installed on remote-controlled boat 1, is used to suction and transport water samples;

[0026] The telescopic tube assembly 3 is connected at one end to the liquid inlet end of the pump suction assembly 2 and the other end is inserted into the water body to change the height at which the pump suction assembly 2 draws water samples.

[0027] Telescopic control component 4 is installed on remote-controlled boat 1 and is used to control the telescopic length of telescopic tube component 3.

[0028] This invention involves placing a remote-controlled boat 1 in the water body to be sampled, controlling the boat 1 to move to the sampling point, and then controlling the telescopic control component 4 to change the telescopic length of the telescopic tube component 3 according to the required sampling height. The telescopic tube component 3 is then extended and inserted to the corresponding water layer height. The pump suction component 2 can then be used to pump the water sample from that water layer for discharge. By receiving the water sample at the outlet end of the pump suction component 2, the water sample collection can be completed. The entire sampling process is not easily limited by the sampling point, achieving the goal of efficiently collecting water samples from various locations in the water body.

[0029] It should be noted that both the remote-controlled boat 1 and the pump suction component 2 are mature existing technologies, and will not be elaborated on further here.

[0030] In practice, to facilitate the sampling personnel's observation of the movement of the remote-controlled boat 1, a monitoring camera is installed on the remote-controlled boat 1, and a locator is also installed on the remote-controlled boat 1 to facilitate the sampling personnel's determination of whether the remote-controlled boat 1 has moved to the correct position.

[0031] In one embodiment, the telescopic tube assembly 3 includes at least two sleeves 31 that are nested together and movable along the axial direction. One of the sleeves 31 is connected to the liquid inlet end of the pump suction assembly 2, and the sleeve 31 is provided with an anti-detachment ring 32 that is inserted into the adjacent sleeve 31. A sliding groove is provided in the corresponding sleeve 31 for the anti-detachment ring 32 to move along the axial direction.

[0032] This design, through the connection of multiple sleeves 31 and the use of anti-detachment rings 32 to prevent two adjacent sleeves 31 from completely disengaging during telescopic adjustment, allows the telescopic tube assembly 3 to freely adjust its length within the maximum adjustment range. Furthermore, since the sleeves 31 are rigid tubes, they will not be affected by water flow and will not shift the measurement point. They will also not be entangled by underwater vegetation and thus unable to telescopically move, resulting in high stability in use.

[0033] It should be noted that, in order to prevent water from entering through the gap between adjacent sleeves 31, the anti-detachment ring 32 is provided with a sealing ring that abuts against the adjacent sleeve 31. In order to ensure that the sleeve 31 can move up and down normally, each sleeve 31 with a sliding groove is also provided with a pressure stabilizing hole communicating with the sliding groove at its top.

[0034] In one embodiment, the telescopic control assembly 4 includes a winding motor and a winding roller disposed at the output end of the winding motor. A pull rope is detachably disposed on the winding roller, and the end of the pull rope away from the winding roller is fixedly connected to the outermost sleeve 31 of the telescopic tube assembly 3.

[0035] With this design, due to the weight of the sleeve 31, it will automatically fall and extend when the sleeve 31 is not restricted. Since the outermost sleeve 31 is connected to the pull rope, the maximum length that multiple sleeves 31 can extend depends on the length of the pull rope. Therefore, the length of the telescopic tube assembly 3 can be quickly adjusted by simply controlling the number of rotations at the output end of the winding motor.

[0036] In one embodiment, the bottom end of the outermost sleeve 31 is provided with an annular counterweight block, and a filter screen is embedded in the annular counterweight block. The bottom ends of the other sleeves 31 are provided with multiple pins corresponding to the filter holes of the filter screen. When the telescopic tube assembly 3 is at its shortest length, each pin is inserted into the filter hole of the filter screen.

[0037] This design utilizes an annular counterweight to increase the downward movement force of the sleeve 31 when it is unrestricted. At the same time, through the cooperation of the filter screen set on the annular counterweight and the push pin set at the bottom of the sleeve 31, when the telescopic tube assembly 3 is extended, the filter screen pores are not affected by the push pin blockage, allowing water to enter normally and intercepting large particles of debris. When the telescopic tube assembly 3 is at its shortest length, the push pin can be inserted into the filter screen pores to push out some of the debris blocking the pores, achieving an automatic unblocking effect and ensuring that the efficiency of the next collection remains unchanged.

[0038] In one embodiment, the outlet end of the pump suction assembly 2 is provided with an outlet assembly 5 capable of changing the outlet position;

[0039] The liquid outlet assembly 5 includes a liquid outlet pipe 51 rotatably disposed at the liquid outlet end of the pump suction assembly 2. The liquid outlet pipe 51 is inverted U-shape. A driven gear 52 that can rotate with the liquid outlet pipe 51 is disposed on the liquid outlet pipe 51. The liquid outlet assembly 5 also includes an angle adjustment motor 53 and a drive gear 54 disposed at the output end of the angle adjustment motor 53. The driven gear 52 and the drive gear 54 mesh with each other.

[0040] This design allows the angle adjustment motor 53 to rotate, causing the outlet pipe 51 to rotate under the cooperation of the driven gear 52 and the driving gear 54, thus changing the outlet position. This enables the remote-controlled boat 1 to have fixed water sample collection positions and waste liquid discharge positions. After the water sample collection at one of the points is completed, the outlet position of the outlet pipe 51 can be changed so that the subsequent discharged liquid is first discharged to the waste liquid discharge position, and the original water sample remaining in the outlet pipe 51 is discharged as waste liquid. After that, it rotates back to the water sample collection position to collect subsequent water samples.

[0041] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0043] Additionally, "multiple" refers to two or more.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
