Description

A sampling device suitable for determining metal elements in water Technical Field

[0001] This utility model relates to the field of metal element determination technology in water, and in particular to a sampling device suitable for metal element determination in water. Background Technology

[0002] Sampling devices for determining metal elements in water are mainly used to collect water samples for subsequent analysis and determination of metal elements in the water. Existing water metal element determination sampling devices have significant shortcomings in terms of the management of the suction pipe's deployment and retraction.

[0003] Due to the lack of effective organization mechanisms, the suction pipes are prone to becoming tangled during deployment and retraction. This tangled state leads to numerous drawbacks. Operationally, operators must expend significant time and effort to straighten the messy pipes, severely impacting the efficiency of water sample collection. From an equipment wear and tear perspective, the tangled suction pipes become intertwined and compressed during frequent deployment and retraction, while also generating excessive friction with other equipment components, greatly increasing the likelihood of pipe wear, bending, and even damage. Once a suction pipe is damaged, it not only requires immediate replacement, increasing equipment maintenance costs and downtime, but also prevents the timely acquisition of qualified water samples, affecting the entire process of metal element determination. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and to propose a sampling device suitable for the determination of metal elements in water.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampling device suitable for determining metal elements in water includes a placement frame, on which a winding roller is rotatably mounted, a water suction tube is wound around the winding roller, and a water suction head is installed on the water suction tube. A water suction pump and a drive motor are mounted on the placement frame via a mounting bracket. The water suction pump is connected to the winding roller via a connecting mechanism, and the output shaft of the drive motor is connected to the winding roller. A screw is mounted on the placement frame via a fixing plate, and the screw is connected to the drive motor via a synchronization mechanism. A nut is threaded onto the screw, and a fixing ring corresponding to the water suction tube is provided on the nut.

[0007] Preferably, the connecting mechanism includes an inlet pipe installed on the water pump, and a connecting pipe is provided on the winding roller through a connecting channel, wherein the inlet pipe and the connecting pipe are rotatably and sealed together.

[0008] Preferably, the synchronization mechanism includes a synchronization pulley mounted on the output shaft of the drive motor and the end of the screw, and the two synchronization pulleys are connected by a synchronization belt.

[0009] Preferably, the end of the water suction pipe is fixedly connected to the winding roller and communicates with the connecting channel, and a filter screen is provided at the water suction port of the water suction head.

[0010] Preferably, a limiting rod is provided between the two fixing plates, the limiting rod being parallel to the screw and slidingly penetrating the nut.

[0011] Preferably, the inner wall of the fixing ring is polished, and the placement frame is provided with multiple round holes.

[0012] The beneficial effects of this utility model are:

[0013] 1. This sampling device possesses a unique sorting capability. During the water suction pipe release process, the nut and retaining ring move along the screw, causing the water suction pipe to be released in an orderly spiral shape, avoiding the water pipes from tangling or knotting. After sampling, the drive motor reverses, and the winding roller retracts the water suction pipe. The nut and retaining ring continue to function, ensuring that the water suction pipe is neatly wound on the winding roller.

[0014] 2. Due to the installation of synchronous pulleys and synchronous belts, the winding roller and screw can rotate synchronously in both directions, eliminating the need for a separate power unit for the screw and ensuring the linkage effect and practicality of the device.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Referring to Figures 1-4, a sampling device suitable for determining metal elements in water includes a placement frame 1, a winding roller 2 rotatably mounted on the placement frame 1, a water suction pipe 12 wound on the winding roller 2, and a water suction head 13 installed on the water suction pipe 12. The water suction head 13 is hollow inside and has a certain weight. After being thrown into the water, it can slowly descend from the water surface to the bottom.

[0022] A water pump 4 and a drive motor 14 are mounted on the placement frame 1 via the mounting frame 3. The water pump 4 is connected to the winding roller 2 via a connecting mechanism. The output shaft of the drive motor 14 is connected to the winding roller 2. A screw 8 is mounted on the placement frame 1 via a fixing plate 7. The screw 8 is connected to the drive motor 14 via a synchronization mechanism. A nut 9 is threaded onto the screw 8. A fixing ring 11 corresponding to the water suction pipe 12 is provided on the nut 9.

[0023] The connecting mechanism includes an inlet pipe 5 installed on the water pump 4, and a connecting pipe 18 provided on the winding roller 2 through the connecting channel 17. The inlet pipe 5 and the connecting pipe 18 are rotatably and sealed together. The connecting pipe 18 rotates together with the winding roller 2.

[0024] The synchronization mechanism includes timing pulleys 15 mounted on the output shaft of the drive motor 14 and the end of the screw 8, with the two timing pulleys 15 connected by a timing belt 16. The timing pulleys 15, in conjunction with the timing belt 16, enable the screw 8 to rotate synchronously with the winding roller 2 and the output shaft of the drive motor 14.

[0025] The end of the suction pipe 12 is fixedly connected to the winding roller 2 and communicates with the connecting channel 17. A filter screen 19 is provided at the suction port of the suction head 13. The filter screen 19 can filter some impurities in the water during water sampling.

[0026] A limiting rod 10 is provided between the two fixing plates 7. The limiting rod 10 is parallel to the screw 8 and slides through the nut 9. The limiting rod 10 limits the nut 9 and prevents the nut 9 from rotating with the screw 8.

[0027] The inner wall of the fixing ring 11 is polished, and the placement frame 1 is provided with multiple round holes 20. These round holes 20 can be used to insert a probe, which ensures the stability of the placement frame 1 when placed on the ground after entering the ground.

[0028] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0029] When using this utility model, the drive motor 14 rotates, which drives the winding roller 2 to rotate, so that the suction pipe 12 can be rotated out. During this process, the suction pipe 12 is dragged and piled up near the placement rack 1. When the suction pipe 12 is completely rotated out, the suction head 13 is grabbed and thrown out forcefully. Then it enters the target water area. At this time, the suction pump 4 is started. The water in the target water area enters the connecting channel 17 through the suction head 13 and the suction pipe 12. Then it enters the suction pump 4 through the connecting pipe 18 and the water inlet pipe 5. Finally, it is discharged through the connecting pipe 18. The water can be collected by a test tube or other components below the connecting pipe 18.

[0030] After sampling is completed, the drive motor 14 starts and reverses, at which time the winding roller 2 rotates to achieve the winding of the water suction pipe 12.

[0031] Regardless of whether the winding roller 2 rotates forward or backward, the screw 8 will follow its rotation. The nut 9 can be moved with the fixing ring 11 to ensure that the suction pipe 12 is released or wound in a spiral shape, ensuring its neatness during release and recovery.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
