Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality testing, and in particular to a foldable telescopic sampling arm for a portable water quality testing instrument. Background Technology
[0002] In the field of water quality testing, water sampling refers to the process of collecting water samples for subsequent analysis. Existing sampling devices are broadly classified into two types: surface sampling and depth sampling. Surface sampling devices have a simpler structure, typically consisting of a bucket with a handle, and sampling is performed manually. Depth sampling devices require a counterweight at the bottom of the bucket and a rope at the top for raising and lowering, which is then raised and lowered by a worker standing at the water's edge using a hand-cranked reel.
[0003] However, all of the above sampling methods require personnel to be able to directly reach the edge of the water to take samples. Some sampling locations are relatively remote or have obstacles, making it difficult for personnel to approach them directly, which increases the difficulty of sampling and makes it impossible to take samples directly using existing sampling equipment or methods.
[0004] Furthermore, when multiple samples need to be collected simultaneously, personnel are required to carry additional sample boxes for storage, but existing sampling devices do not have the function of temporary sample storage, resulting in low sampling efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a portable water quality analyzer with a foldable telescopic sampling arm that can conveniently sample locations that are difficult to sample directly and can temporarily store the sampled samples.
[0006] To solve the above-mentioned technical problems, this utility model provides a portable water quality tester foldable telescopic sampling arm, including a telescopic arm body, a fixed base connected to one end of the telescopic arm body, and a sampling head assembly connected to the other end of the telescopic arm body. The sampling head assembly includes a limiting frame rotatably connected to the end of the telescopic arm body and a sampling bottle detachably connected to the limiting frame. Furthermore, storage components are symmetrically arranged on both sides of the end of the telescopic arm body near the fixed base. The storage components include a foldable storage bag.
[0007] Furthermore, the storage assembly also includes a support frame disposed on the side of the telescopic arm body, a first positioning rod and a second positioning rod rotatably connected to the support frame, the support frame having a first limiting rod at both ends, and the ends of the first positioning rod and the second positioning rod having a second limiting rod, so that the hanging opening on the outer periphery of the storage bag is fitted onto the first limiting rod and the second limiting rod.
[0008] Furthermore, a first adjusting block is rotatably provided on the side of the first positioning rod away from the storage bag, and a second adjusting block is rotatably provided on the side of the second positioning rod away from the storage bag, and an elastic element connects the first adjusting block and the second adjusting block.
[0009] Furthermore, the fixed seat side is connected to a positioning frame via at least two telescopic rods, and the support frame is connected to the side of the positioning frame.
[0010] Furthermore, the sampling head assembly also includes a detachable positioning frame connected to the limiting frame, wherein the positioning frame has several hollowed-out grooves spaced apart on its outer periphery, and the sampling bottle is placed in the positioning frame.
[0011] Furthermore, the opening of the positioning frame is provided with an adhesive strip along the circumference so that the outer periphery of the sampling bottle is in contact with the adhesive strip.
[0012] Furthermore, a pipe is installed at the fixed base, and the pipe is connected to the telescopic arm body.
[0013] Furthermore, the fixed base has a handle on its side.
[0014] The beneficial effects of this utility model are as follows: By controlling the extension length of the limiting frame through the telescopic control of the telescopic arm body, the limiting frame can drive the sampling bottle inside to extend into the target water area for sampling. The rotating setting of the limiting frame allows the sampling bottle to be tilted to collect water when sampling water quality, making it easier to expel air from the sampling bottle and thus enabling the sampling bottle to quickly complete the water filling operation. At the same time, the foldable storage bag structure can be folded and stored when not in use, saving space and making it easy to carry. When it is necessary to place the sampling bottle in the storage bag, the storage bag can be unfolded to make reasonable use of its internal space to arrange the sampling bottle, increasing the temporary storage space without the need to carry an additional storage container.

[0021] 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 some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0022] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.
[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0024] like Figures 1-5 The present invention provides a portable water quality analyzer foldable telescopic sampling arm, including a telescopic arm body 1, a fixed base 2 connected to one end of the telescopic arm body 1, and a sampling head assembly connected to the other end of the telescopic arm body 1. The sampling head assembly includes a limiting frame 3 rotatably connected to the end of the telescopic arm body 1 and a sampling bottle detachably connected to the limiting frame 3. Storage components are symmetrically arranged on both sides of the end of the telescopic arm body 1 near the fixed base 2. The storage components include a foldable storage bag 4.
[0025] The extension length of the limiting frame 3 is controlled by the telescopic arm body 1, allowing the limiting frame 3 to extend the sampling bottle inside to the target water area for sampling. The rotating setting of the limiting frame 3 allows the sampling bottle to be tilted to collect water when sampling water quality, making it easier to expel air from the sampling bottle and thus enabling the sampling bottle to quickly complete the water filling operation. At the same time, the foldable storage bag 4 structure can be folded and stored when not in use, saving space and making it easy to carry. When it is necessary to place the sampling bottle in the storage bag 4, the storage bag 4 can be unfolded to make reasonable use of its internal space to arrange the sampling bottle, increasing the temporary storage space without the need to carry an additional storage container.
[0026] The sampling bottle is a transparent bottle-shaped structure to facilitate observation of the water quality sampling status inside; the storage bag 4 is made of elastic fabric to facilitate stretching when folded.
[0027] In one embodiment of this solution, a pipe 19 is installed at the fixed base 2, and the pipe 19 is connected to the telescopic arm body 1. The pipe 19 is used to control the air pressure or hydraulic pressure, thereby controlling the extension and retraction of the telescopic arm body 1 through air pressure or hydraulic pressure. When using air pressure or hydraulic pressure to control the extension and retraction, a small air pump or hydraulic pump is required to be connected to the pipe 19.
[0028] In another embodiment of this solution, an electric push rod structure can be set at the fixed base 2. The extension and retraction of the telescopic arm body 1 can be controlled by the electric push rod, or the telescopic arm can be manually controlled in conjunction with the buckle for fixation. When the telescopic arm body 1 is in use, the buckle is opened to extend it. After sampling is completed, it is manually retracted and the length is limited by the buckle. The specific control method of the telescopic arm body 1 can be selected and designed according to different sampling requirements.
[0029] Preferably, the storage assembly further includes a support frame 5 disposed on the side of the telescopic arm body 1, a first positioning rod 6 and a second positioning rod 7 rotatably connected to the support frame 5, the support frame 5 having a first limiting rod 8 at both ends, and the ends of the first positioning rod 6 and the second positioning rod 7 having a second limiting rod 9, so that the hanging opening 10 on the outer periphery of the storage bag 4 is fitted onto the first limiting rod 8 and the second limiting rod 9.
[0030] Specifically, the first limiting rod 8 and the second limiting rod 9 are supported at the hanging opening 10, so that the outer periphery of the storage bag 4 is opened by the first limiting rod 8 and the second limiting rod 9, which can ensure that the storage bag 4 is in an unfolded state, making it easy to place and take out the sampling bottle. At the same time, when it is necessary to fold the storage bag 4, by rotating the first positioning rod 6 and the second positioning rod 7, the second limiting rod 9 drives one side of the storage bag 4 to fold. After the first positioning rod 6 and the second positioning rod 7 are rotated to the side of the support frame 5, the storage bag 4 can be folded to the side of the telescopic arm body 1 by the second limiting rod 9, reducing the usable space.
[0031] In one embodiment of this solution, the support frame 5 is arranged in an "L" shape, and when the support frame 5, the first positioning rod 6 and the second positioning rod 7 are unfolded, they together form a "+" shape, so that the first limiting rod 8 and the second limiting rod 9 support the four corners of the storage bag 4.
[0032] Preferably, a first adjusting block 11 is rotatably provided on the side of the first positioning rod 6 away from the storage bag 4, and a second adjusting block 12 is rotatably provided on the side of the second positioning rod 7 away from the storage bag 4, and an elastic member 13 is connected between the first adjusting block 11 and the second adjusting block 12.
[0033] Specifically, when adjusting the positions of the first positioning rod 6 and the second positioning rod 7 to control the unfolding or folding state of the storage bag 4, the first positioning rod 6 and the second positioning rod 7 are simultaneously rotated. The first adjusting block 11 and the second adjusting block 12 pull the elastic element 13 to extend. When the elastic element 13 moves with the rotation of the positioning rods past the axis of rotational connection between the support frame 5, the first positioning rod 6, and the second positioning rod 7, the elastic element 13 contracts and automatically rebounds, thereby resetting the distance between the first positioning rod 6 and the second positioning rod 7, so as to achieve the automatic adjustment effect of folding or unfolding.
[0034] Among them, the elastic element 13 can be a spring structure.
[0035] Preferably, the fixed base 2 is connected to a positioning frame 15 by at least two telescopic rods 14 on its side, and the support frame 5 is connected to the side of the positioning frame 15.
[0036] Specifically, the positioning frame 15 stabilizes the support frame 5, thereby ensuring the stability of the storage bag 4. At the same time, due to the setting of the telescopic rod 14, when adapting to sampling bottles of different specifications, the distance between the positioning frame 15 and the fixed base 2 can be adjusted, thereby ensuring sufficient storage space for storage bags 4 of different sizes.
[0037] In one embodiment of this solution, one of the telescopic rods 14 is a threaded telescopic rod 14, which can be adjusted by rotating the telescopic rod 14 to control the distance between the positioning frame 15 and the fixed seat 2, and the end of the threaded telescopic rod 14 is in rotational engagement with the positioning frame 15.
[0038] Preferably, the sampling head assembly further includes a positioning frame 16 detachably connected to the limiting frame 3, wherein the positioning frame 16 has a plurality of hollow grooves 17 spaced apart on its outer periphery, and the sampling bottle is placed in the positioning frame 16.
[0039] Specifically, the positioning frame 16 is connected to the limiting frame 3, and the sampling bottle is supported by the positioning frame 16 to ensure the stability of the sampling bottle during the sampling process. At the same time, the design of the hollow groove 17 makes it easy to observe the placement status of the sampling bottle, the sampling volume, etc. Since the positioning frame 16 is detachable, it can be quickly disassembled and replaced with a suitable positioning frame 16 when it is necessary to change the sampling bottle of different specifications, thereby improving the versatility and convenience of the overall device.
[0040] The positioning frame 16 can be connected to the limiting frame 3 by means of a threaded connection.
[0041] Preferably, the opening of the positioning frame 16 is provided with an adhesive strip 18 along the circumference so that the outer periphery of the sampling bottle is in contact with the adhesive strip 18. When the sampling bottle is placed in the positioning frame 16, the adhesive strip 18 can limit the outer periphery of the sampling bottle and prevent the sampling bottle from falling to the outside of the positioning frame 16, thereby improving the sampling stability of the sampling bottle.
[0042] Preferably, the fixed base 2 has a handle 20 on one side, so that the user can easily carry the sampling arm structure of this solution by pulling the handle 20, and ensure the overall structural stability during the sampling process.
[0043] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
