[0023] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the embodiments described are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] See also Figure 1 and Figure 2 The present application first provides an embodiment of a tank sampler, which comprises: Protective cover 01, sampling barrel 02, drive assembly 03, cylindrical connecting ring 04, cover plate 05 and connecting rope 06; One end of the cylindrical connecting ring is connected to the tank body 07, and the other end is connected to the protective cover 01. The cylindrical connecting ring 04 and the protective cover 01 are used to prevent the liquid in the sampling barrel 02 from splashing; The driving assembly 03 is arranged above the protective cover 01 and is connected to the sampling barrel 02 through the connecting rope 06. The driving assembly 03 is used to reel or unreel the connecting rope 06 to lift and lower the sampling barrel 02. A cover plate 05 is provided in the protective cover 01, and the cover plate 05 is used to seal the tank body 07 and prevent the operator from stepping into empty space.

[0025] Protective cover 01: Protective cover 01 has a hood-like structure with a defined space, accommodating the active area of ​​sampling barrel 02 and covering the sampling area. Protective cover 01 prevents splashing of liquid within sampling barrel 02, preventing injury to the operator and contamination of the surrounding environment. Protective cover 01 is welded to a cylindrical connecting ring 04, creating a relatively enclosed space and ensuring that sampling operations are conducted within a defined protective envelope. Protective cover 01 is typically constructed of corrosion-resistant, high-strength materials, such as stainless steel or engineering plastics, to adapt to the working environment surrounding the extraction tank, protect against chemical corrosion, and withstand certain external forces.

[0026] Sampling Bucket 02: Sampling Bucket 02 is cylindrical or square, or other shapes suitable for holding liquids and easily raised and lowered. In this application, drive assembly 03 controls the raising and lowering of sampling bucket 02 via connecting rope 06, thereby enabling sampling from tank 07. Sampling Bucket 02 is typically constructed of corrosion-resistant materials, such as stainless steel or polytetrafluoroethylene, to ensure resistance to corrosion from various chemical liquids, maintain sampling accuracy, and extend the life of the bucket.

[0027] Drive Assembly 03: Drive Assembly 03 can be implemented in a variety of ways, including a hand-cranked winch, lever-and-pulley mechanism, and motor-driven configurations. Drive Assembly 03 needs to be suitable for use in corrosive environments such as phosphoric acid extraction tanks. It can be constructed of corrosion-resistant and durable metal to prevent corrosion from the liquid during the sampling process, which can impact its service life. Drive Assembly 03 is secured above Protective Cover 01. By reeling in or unreeling Connecting Rope 06, it controls the raising and lowering of Sampling Bucket 02, effectively controlling its position and completing the sampling operation.

[0028] Cylindrical Connecting Ring 04: This hollow cylindrical ring connects the tank body 07 and the protective cover 01 at either end. Made of the same corrosion-resistant, high-strength material as the protective cover 01, it ensures a secure connection and long-term stability. It connects and secures the protective cover 01 and, together with the protective cover 01, prevents liquid from splashing within the sampling barrel 02. Structurally, the protective cover 01 and tank body 07 form a single unit, ensuring that sampling is performed in a relatively closed environment and enhancing safety.

[0029] Cover 05: Installed within protective cover 01, cover 05 conforms to the cross-section of protective cover 01 and may be round, square, or similar in shape to completely cover the opening of tank 07. Cover 05 is constructed of a high-strength material, such as metal or high-strength engineering plastic, to withstand pressure and prevent operators from stepping on empty space. Cover 05 also seals tank 07, preventing the liquid from evaporating or spilling, as well as preventing foreign matter from entering and impacting the extraction process. To ensure a secure seal, the edges of cover 05 can be provided with a flexible sealing material.

[0030] Connecting Rope 06: Connecting Rope 06 connects Drive Assembly 03 and Sampling Bucket 02. Drive Assembly 03 winds or unwinds it, enabling the lifting and lowering of Sampling Bucket 02. It serves as the connecting component that allows Drive Assembly 03 to control the position of Sampling Bucket 02. Connecting Rope 06 is typically a slender, high-strength, and wear-resistant rope, such as a steel wire rope or high-strength synthetic fiber rope. This prevents it from breaking during frequent winding and unwinding, reliably transmitting power from Drive Assembly 03 and controlling the lifting and lowering of Sampling Bucket 02.

[0031] Working Principle: To sample the liquid in tank 07, the operator first opens cover 05 of protective cover 01 and simultaneously uses drive assembly 03 to unwind connecting rope 06, causing sampling bucket 02 to descend, pass through protective cover 01 and cylindrical connecting ring 04, and enter tank 07 for sampling. Once sampling bucket 02 has collected the desired liquid, the operator again uses drive assembly 03 to rewind connecting rope 06, causing sampling bucket 02 to ascend, passing through cylindrical connecting ring 04 and protective cover 01. Once it reaches a position where the operator can access sampling bucket 02, the operator closes cover 05 of protective cover 01, creating a sealed space between tank 07, cylindrical connecting ring 04, and protective cover 01.

[0032] In this embodiment, the tank sampler acts on the tank body 07 of the extraction tank. It is composed of a protective cover 01, a sampling barrel 02, a drive assembly 03, a cylindrical connecting ring 04, a cover plate 05, and a connecting rope 06 to form a winch-shaped tank sampler. The drive assembly 03 reels and unreels the connecting rope 06 to achieve the lifting and lowering movement of the sampling barrel 02, which can make the sampling process more labor-saving and convenient, and improve the efficiency of sampling. The tank sampler is provided with a protective cover 01 and a cylindrical connecting ring 04, and the protective cover 01 is provided with a cover plate 05. The protective cover 01 and the cylindrical connecting ring 04 can prevent the liquid in the sampling barrel 02 from splashing. The cover plate 05 can seal the extraction tank and prevent the operator from stepping on air, which can improve the safety during sampling.

[0033] See also Figures 1 to 4The drive assembly 03 can be implemented in a variety of ways, such as a hand-cranked winch structure, a lever pulley structure, and a motor-driven structure. The present application provides a preferred embodiment, which includes: The driving assembly 03 includes a handle 31, a connecting shaft 32 and two support frames 33; Two support frames 33 are connected to the protective cover 01; Both ends of the connecting shaft 32 are rotatably connected to the top ends of the two supporting frames 33 respectively; One end of the connecting shaft 32 is connected to the rotating handle 31; The connecting shaft 32 is connected to the sampling barrel 02 via a connecting rope 06; The handle 31 includes a connecting rod 311, a T-shaped rod 312 and a sleeve 313; The connecting rod 311 is connected to one end of the connecting shaft 32; The T-shaped rod 312 is connected to the connecting rod 311 and is placed in the sleeve 313 .

[0034] Turning handle 31: The turning handle 31 needs to be made of a material with high strength and good corrosion resistance, which can withstand the force applied by the operator when turning and adapt to different working environments, especially in environments where corrosive substances are present, such as phosphoric acid extraction. The turning handle 31 is composed of a connecting rod 311, a T-shaped rod 312 and a sleeve 313. One end of the connecting rod 311 is detachably connected to the connecting shaft 32 through a connector 34, and the other end is detachably connected to the T-shaped rod 312. The turning handle 31 will be subjected to a large force during operation, so it needs to be maintained on time. The detachable structure allows the components in the turning handle 31 to be replaced individually during daily maintenance, which increases the safety of the drive assembly 03 and can reduce costs to a certain extent. The sleeve 313 is a hollow tube with an inner diameter that matches the crossbar portion of the T-bar 312 and can be sleeved on the outside of the T-bar 312. The sleeve 313 is the position for the operator to grasp. The surface of the sleeve 313 is provided with an anti-slip sleeve 314, such as diamond or strip-shaped patterns. The anti-slip sleeve 314 can increase the friction when the operator grasps it, so that the operator can hold the sleeve 313 more stably, reduce operational errors caused by hand slippage, and improve the safety and comfort of operation.

[0035] Connecting shaft 32: Connecting shaft 32 is typically cylindrical and rotatable. Its smooth surface facilitates the winding and sliding of the connecting rope 06, reducing friction between the connecting rope 06 and the connecting shaft 32, ensuring smoother winding and unwinding of the connecting rope 06. To withstand the tension generated by the connecting rope 06 during winding and unwinding, as well as the torque transmitted by the handle 31, the connecting shaft 32 is typically constructed of a high-strength metal material, such as alloy steel. Annular retaining grooves 321 are provided on the exterior of each end of the connecting shaft 32, securing the connecting shaft 32 to the support frame 33 and enabling rotation. Two retaining rings 322 are located in the middle of the connecting shaft 32, between which the connecting rope 06 is wound. These retaining rings 322 effectively prevent the connecting rope 06 from drifting during winding and unwinding, ensuring that the connecting rope 06 is neatly wound around the connecting shaft 32 and preventing the connecting rope 06 from becoming entangled or detaching from the connecting shaft 32, thereby improving the stability and reliability of the drive assembly 03.

[0036] Support frame 33: Support frame 33 primarily supports and secures connecting shaft 32. Connected to protective cover 01, the two support frames 33 stand opposite each other, securing the entire drive assembly 03 above protective cover 01. This allows the connecting shaft 32 to rotate stably on the top of the support frame 33. Furthermore, the support frame 33 can withstand the reaction force generated by the rotation of the connecting shaft 32, ensuring the overall stability of the drive assembly 03. To firmly support the weight of the connecting shaft 32 and the entire drive assembly 03, the support frame 33 is typically constructed of metal, such as angle steel. A circular ferrule 331 is secured to the top of the support frame 33. This mates with annular grooves 321 on the outside of the connecting shaft 32, further stabilizing the connection between the connecting shaft 32 and support frame 33 while ensuring the flexible rotation of the connecting shaft 32. A recess 332 on the top of the support frame 33 serves to position and secure the circular ferrule 331, preventing it from shifting during use.

[0037] Working principle: The operator grasps the sleeve 313 of the rotating handle 31 and applies force, and transmits the force to the connecting shaft 32 with the help of the T-bar 312 and the connecting rod 311, so that the connecting shaft 32 rotates in the circular sleeve 331 of the support frame 33, driving the connecting rope 06 to reel or unreel between the two limiting rings 322 in the middle of the connecting shaft 32, thereby realizing the lifting and lowering movement of the sampling barrel 02.

[0038] In this embodiment, the driving assembly 03 of the trough sampler is composed of a rotating handle 31, a connecting shaft 32 and two support frames 33. The annular grooves 321 on the outside of the two ends of the connecting shaft 32 cooperate with the circular sleeves 331 of the support frames 33, so that the connecting shaft 32 can rotate stably. The limiting ring 322 in the middle of the connecting shaft 32 prevents the connecting rope 06 from deviating, which is conducive to the smooth retraction and release of the connecting rope 06, and improves the stability and reliability of the driving assembly 03. When sampling, the operator rotates the rotating handle 31 to rotate the connecting shaft 32, driving the connecting rope 06 to reel in and unreel, thereby realizing the lifting and lowering of the sampling bucket 02. The use of a simple driving assembly 03 allows the operator to flexibly adjust the rotation speed according to actual conditions to control the lifting and lowering of the sampling bucket 02, effectively saving manual physical exertion and improving the efficiency of sampling.

[0039] See also Figure 1 and Figure 2 In an optional embodiment, the sampling bucket 02 includes a sampling bucket body 21 and a sampling bucket handle 22; a hole 23 is provided on the outer wall of the sampling bucket body 21, and the sampling bucket handle 22 is connected to the sampling bucket body 21 through the hole 23; the connecting shaft 32 is connected to the middle part of the sampling bucket handle 22 through the connecting rope 06.

[0040] In this embodiment, the sampling bucket body 21 and the sampling bucket handle 22 are connected through holes 23 on the outer wall. The sampling bucket handles 22 are located on both sides of the sampling bucket body 21, making it convenient for the operator to hold the sampling bucket 02 for operation and to maintain balance when extracting samples. The connection through the hole 23 facilitates the installation and removal of the sampling bucket handle 22. If the sampling bucket handle 22 or the sampling bucket body 21 is damaged, they can be replaced separately, reducing maintenance costs and difficulty. The connecting shaft 32 is connected to the middle of the sampling bucket handle 22 through the connecting rope 06. When the drive assembly 03 is running and the connecting shaft 32 rotates to retract and release the connecting rope 06, since the connection point is located in the middle of the sampling bucket handle 22, it can ensure that the sampling bucket 02 is evenly stressed during the lifting process and moves vertically up and down, reducing factors that cause sample spillage due to tilting.

[0041] It should be noted that the above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
