Description

Technical Field

[0001] This utility model relates to the field of hanging rack technology, specifically to a hanging rack for a portable water quality sampler. Background Technology

[0002] A portable water quality sampler hanger is an auxiliary device used with portable water quality samplers. It is usually made of lightweight and corrosion-resistant materials (such as aluminum alloy and engineering plastics) and features a foldable and easily detachable structure. Through hooks, buckles, or straps, the sampler can be securely mounted on the back, arm, or sampling boat / pole of the sampling personnel. This frees up the hands of the sampling personnel in complex water environments such as rivers, lakes, and reservoirs, enabling them to carry out mobile sampling operations more flexibly and safely, improving sampling efficiency and reducing the burden of operation. For example, a new type of sampler hanger is disclosed in Chinese Patent Publication No. CN213481825U.

[0003] Existing portable water quality sampler racks have limitations because their fixing angle and strength cannot be adjusted according to the type of sampler and sampling requirements. This results in poor adaptability when dealing with samplers of different sizes and weights, posing a risk of insecure fixing or damage to the equipment due to excessive pressure. Furthermore, in special sampling scenarios, such as high-altitude sampling and deep-water sampling, the rack angle cannot be flexibly adjusted, restricting the operation of sampling personnel, increasing sampling difficulty and safety hazards, and failing to meet the diverse needs of water quality sampling work. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a portable water quality sampler holder, which can effectively solve the problem that the fixing angle and fixing strength of the sampler in the existing technology cannot be changed according to the type of sampler and the sampling requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a portable water quality sampler holder, including:

[0007] The mounting plate is equipped with angle adjustment components on all four sides;

[0008] The angle adjustment component includes a fixed block fixedly connected to the side, a rotating shaft fixedly connected to the bottom of the fixed block, a rotating component rotatably connected to the shaft of the rotating shaft, a rotating telescopic rod snapped into the bottom of the rotating component, and a pneumatic component provided at the other end of the rotating telescopic rod.

[0009] Furthermore, the pneumatic assembly includes an air box snapped onto the other side of the rotating telescopic rod. A piston is slidably connected inside the air box, and a stop rod is fixedly connected to the side of the piston. The other side of the stop rod passes through the air box and extends outside the air box. A positioning telescopic rod is fixedly connected to the air box on one side of the stop rod. The other side of the positioning telescopic rod is fixedly connected to the stop rod. A mounting plate is fixedly connected to the side of the air box away from the stop rod.

[0010] Furthermore, a multi-port air distribution valve is fixedly connected to both sides of the air box along the length direction near the mounting plate. The multi-port air distribution valve has multiple output ends and one input end, and the input end of the multi-port air distribution valve is connected to the air box through a pipe. A single-port air valve is fixedly connected to both sides of the air box along the width direction near the mounting plate, and the input end of the single-port air valve is connected to the air box through a pipe.

[0011] Furthermore, multiple adsorption components are provided around the other side of the mounting plate. Each adsorption component includes a connecting square tube fixedly connected to the side of the mounting plate facing the gas box. A connecting tube is fixedly connected to the side of the connecting square tube away from the mounting plate. The other side of the connecting tube is connected to any one of the output ends of a single-port gas valve or a multi-port gas distribution valve. A valve is installed on the body of the connecting tube.

[0012] Furthermore, a positioning block is fixedly connected to the side of the mounting plate away from the air box, and a flexible tube is fixedly connected to the other side of the positioning block. The other side of the connecting square tube passes through the mounting plate, the positioning block and the flexible tube. A fixing frame is fixedly connected to the other side of the flexible tube. Sealing strips are fixedly connected to all four sides of the other side of the fixing frame. A fixing plate is fixedly connected to the inside of the fixing frame near the sealing strip. Multiple suction guide structures are arranged in a linear array on the side of the fixing plate.

[0013] Furthermore, the suction guiding structure includes a hollow strip fixedly connected to the side of the fixed plate. Multiple grooves are linearly arranged on both sides of the hollow strip along its length. Multiple guide covers are linearly connected to both sides of the hollow strip located in the grooves. The grooves and guide covers are alternately arranged inside the hollow strip.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. The angle adjustment component allows for adjustment of the angles of the subsequent pneumatic and adsorption components, enabling the adsorption components to adsorb and fix different types (specifications) of samplers. The pneumatic component only needs to provide the corresponding suction force for the subsequent adsorption components to adsorb onto the sampler surface. Thus, the adsorption components can implement corresponding adsorption requirements for the sampler according to its type and sampling specifications. By using the pneumatic component to provide suction force as needed, the adsorption components can achieve diversified adsorption and fixation of samplers. This not only improves the versatility and flexibility of the equipment and effectively reduces the adaptation cost caused by differences in sampler specifications, but also ensures the stability and reliability of the adsorption process.

[0016] 2. Multiple adsorption components are distributed around the perimeter of the same side of the mounting plate, providing corresponding positions and numbers of adsorption components according to the type and specifications of the sampler. Each adsorption component has a connecting tube that connects to the air pressure component, transmitting the negative pressure generated by the air pressure component to the connecting square tube, then to the flexible tube, and finally to the fixed frame. The fixed frame, in conjunction with a sealing strip, completes the adsorption with the sampler surface. Furthermore, by installing valves on the connecting tubes, the tubes can be blocked, thus disabling the corresponding adsorption component's adsorption capacity. This limits the number and location of adsorption components used on the mounting plate. The valves on the connecting tubes can freely block specific adsorption components, flexibly limiting the number and location of adsorption components used. This improves adaptability to different samplers and adsorption stability, enhances operational flexibility and controllability, and effectively improves work efficiency and practicality.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Example: Refer to Figures 1 to 8 Portable water quality sampler holder, including:

[0034] Hanging plate 1, with angle adjustment components 2 installed on all four sides of the hanging plate 1;

[0035] The angle adjustment component 2 includes a fixed block 21 fixedly connected to the side, a rotating shaft 22 fixedly connected to the bottom of the fixed block 21, a rotating component 23 rotatably connected to the shaft of the rotating shaft 22, a rotating telescopic rod 24 snapped into the bottom of the rotating component 23, and a pneumatic component 3 provided at the other end of the rotating telescopic rod 24.

[0036] The rotating shaft 22 is fixed by the fixing block 21 in the angle adjustment component 2, and the rotating part 23 is rotated and connected to the rotating shaft 22 to adjust the angle of the rotating telescopic rod 24 fixed in the rotating part 23. This allows the angle of the air pressure component 3 and the adsorption component 4 subsequently set in the rotating telescopic rod 24 to meet the type (specification). The rotating telescopic rod 24 is extended or retracted by manual rotation, thereby adjusting the height of the air pressure component 3 and the adsorption component 4.

[0037] Reference Figures 2 to 3 The pneumatic assembly 3 includes an air box 31 that is snapped onto the other side of the rotating telescopic rod 24. A piston is slidably connected inside the air box 31. A stop rod 32 is fixedly connected to the side of the piston. The other side of the stop rod 32 passes through the air box 31 and extends outside the air box 31. A positioning telescopic rod 33 is fixedly connected to the side of the air box 31 located on the stop rod 32. The other side of the positioning telescopic rod 33 is fixedly connected to the stop rod 32. A mounting plate 36 is fixedly connected to the side of the air box 31 away from the stop rod 32.

[0038] By using the air box 31 in the pneumatic assembly 3 in conjunction with the piston and the stopper rod 32, suction can be generated. By pulling the stopper rod 32, the piston can move within the air box 31, thereby generating suction. The magnitude of the suction is determined by the length to which the stopper rod 32 is pulled. The positioning telescopic rod 33 can lock the stopper rod 32 after it has been pulled to a certain length.

[0039] Reference Figures 2 to 4 A multi-port air distribution valve 34 is fixedly connected to both sides of the air box 31 near the mounting plate 36 along its length. The multi-port air distribution valve 34 has multiple output ends and one input end. The input end of the multi-port air distribution valve 34 is connected to the air box 31 through a pipe. A single-port air valve 35 is fixedly connected to both sides of the air box 31 near the mounting plate 36 along its width. The input end of the single-port air valve 35 is connected to the air box 31 through a pipe.

[0040] The single-port gas valve 35 and the multi-port gas distribution valve 34 in the gas box 31 are used to achieve individual connection with multiple adsorption components 4.

[0041] Reference Figure 4 Multiple adsorption components 4 are provided around the other side of the mounting plate 36. Each adsorption component 4 includes a connecting square tube 41 fixedly connected to the side of the mounting plate 36 facing the gas box 31. A connecting tube 42 is fixedly connected to the side of the connecting square tube 41 away from the mounting plate 36. The other side of the connecting tube 42 is connected to any one of the output ends of the single-port gas valve 35 and the multi-port gas distribution valve 34. A valve 43 is installed on the body of the connecting tube 42.

[0042] The mounting plate 36 is used to distribute multiple adsorption components 4. According to the type and sampling specifications of the sampler, the corresponding position and number of adsorption components 4 are provided. The connecting pipe 42 is connected to any one of the output ends of the single-port gas valve 35 or the multi-port gas distribution valve 34 to transmit the negative pressure generated by the gas box 31. The valve 43 of the connecting pipe 42 can block the connecting pipe 42, thereby causing the corresponding adsorption component 4 to lose its adsorption capacity, so as to limit the number and position of the adsorption components 4 in the mounting plate 36.

[0043] Reference Figures 5 to 7 A positioning block 44 is fixedly connected to the side of the mounting plate 36 away from the air box 31. A flexible tube 45 is fixedly connected to the other side of the positioning block 44. The other side of the connecting square tube 41 passes through the mounting plate 36, the positioning block 44 and the flexible tube 45. A fixing frame 46 is fixedly connected to the other side of the flexible tube 45. Sealing strips 47 are fixedly connected to all four sides of the other side of the fixing frame 46. A fixing plate 48 is fixedly connected to the inside of the fixing frame 46 near the sealing strips 47. Multiple suction guide structures 49 are arranged in a linear array on the side of the fixing plate 48.

[0044] The negative pressure is further transmitted to the flexible tube 45 through the connecting tube 42, and finally to the fixed frame 46 through the flexible tube 45. The fixed frame 46, together with the sealing strip 47, completes the adsorption with the sampler surface. The flexible tube 45 is flexible, which makes it easier to adjust the position of the fixed frame 46 on the sampler surface.

[0045] Reference Figure 7 The suction guiding structure 49 includes a hollow strip 491 fixedly connected to the side of the fixed plate 48. Multiple grooves 492 are linearly arranged on both sides of the hollow strip 491 in the length direction. Multiple guide covers 493 are linearly connected to both sides of the hollow strip 491 in the grooves 492. The grooves 492 and guide covers 493 are alternately arranged inside.

[0046] The suction force is guided and concentrated by the suction force guiding structure 49 in the fixed frame 46, thereby concentrating the suction force. The groove 492 in the hollow strip 491 of the suction force guiding structure 49 plays a guiding role in the suction force, while the guide cover 493 plays a concentrating role in the suction force.

[0047] The working principle of this utility model is as follows:

[0048] First, the fixing block 21 is fixed to the side of the hanging plate 1. The rotating part 23 is rotatably connected to the fixing block 21 through the rotating shaft 22. Then, the tilt angle of the rotating telescopic rod 24 can be adjusted by manually moving the rotating part 23 according to the current sampler specifications, so that the air pressure component 3 and the adsorption component 4 can adapt to the installation angle requirements of samplers of different specifications. The length of the rotating telescopic rod 24 can be changed by manually rotating it, thereby adjusting the vertical height of the air pressure component 3 and the adsorption component 4 to match the size of the sampler.

[0049] In this system, after the rotating telescopic rod 24 has completed the angle and height adjustment, the operator pulls the stopper rod 32 from the outside, which moves the piston inside the air box 31, creating a negative pressure (suction) inside the air box 31. The magnitude of the suction is determined by the pulling length of the stopper rod 32. The positioning telescopic rod 33 locks after the stopper rod 32 is pulled to the appropriate position, maintaining the negative pressure state. The multi-port air distribution valve 34 is located on both sides of the length direction of the air box 31. Each air distribution valve has multiple output ends and can connect to multiple adsorption components 4 at the same time, which is suitable for scenarios that require large-area adsorption. The single-port air valve 35 is located on both sides of the width direction of the air box 31. Each air valve connects to only one adsorption component 4, which is suitable for scenarios that require precise control of a single adsorption point.

[0050] In this design, one end of the connecting pipe 42 of the adsorption component 4 is connected to one of the output ends of the multi-port gas valve 34 or the single-port gas valve 35, and the other end is connected to the flexible pipe 45 through the connecting square pipe 41. When the valve 43 on the connecting pipe 42 is opened, the negative pressure is transmitted to the fixed frame 46 through the pipe; when the valve 43 is closed, the negative pressure is blocked, and the function of the corresponding adsorption component 4 is stopped. By opening or closing the valve 43, the negative pressure connection between the corresponding adsorption component 4 and the gas pressure component 3 can be controlled. This allows for flexible blocking of the connecting pipe 42 of the adsorption component 4 that is not in use, based on the sampler's specifications and shape, leaving only the components in specific positions to work. This limits the number and position of the adsorption components 4 used, avoids excessive adsorption force causing equipment compression or instability, and improves adaptability, operational flexibility, and adsorption stability.

[0051] The flexible tube 45 is flexible and can adapt to the irregular shape of the sampler surface. The fixing frame 46 is attached to the sampler surface, and the sealing strip 47 around the fixing frame 46 forms a sealed cavity.

[0052] The fixed frame 46 fits against the surface of the sampler, and the sealing strips 47 around it form a sealed environment to prevent air leakage from affecting the adsorption force. The suction guiding structure 49 (hollow strip 491, groove 492, guide cover 493) on the fixed plate 48 guides and gathers the negative pressure. The hollow strip 491 serves as an airflow channel, and the grooves 492 on both sides inside guide the airflow direction to make the negative pressure evenly distributed. The guide covers 493 are arranged in an array to gather the dispersed airflow into concentrated suction and enhance the adsorption stability.

[0053] This solves the problem in special scenarios such as high-altitude or deep-water sampling, by adjusting the length of the rotating telescopic rod 24 and the angle of the rotating component 23 to adapt the adsorption assembly 4 to the installation direction of the sampler, thereby improving operational flexibility and reducing safety hazards.

[0054] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
