[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by setting up a filter assembly, when the drive motor on the housing is started, the drive motor drives the threaded rod to rotate, and the support blocks on both sides will drive the corresponding limit rods to slide on the connecting frame. The limit rods drive the baffle to move synchronously, which helps to keep the protective net and the sampling tube moving in the same direction. At the same time, the support blocks on both sides will stretch the compression spring on the connecting frame. At this time, the sampling tube and the protective net will enter the water synchronously, and then filter the water collected by the sampling tube through the protective net. This helps to filter out some larger particles in the water, preventing some impurities and larger particles from clogging the opening of the sampling tube, and also preventing some impurities from adhering to the sampling tube, which helps to improve the accuracy of water detection.

[0019] 2. In this utility model, by setting an adjustment component, when water samples need to be taken for testing, the distance of the sampling tube on the moving plate is first adjusted according to the required sampling location. At this time, the lever is released, and under the elastic force of the telescopic spring, the telescopic spring pulls the positioning rod into the positioning hole of the fixed sleeve through the lever, thereby keeping the moving sleeve in a fixed state. At the same time, the moving sleeve keeps the moving plate and the sampling tube in a stable state through the drive frame. The distance adjustment helps to improve the flexibility of the equipment, making it easier for the equipment to collect water samples from some distant locations, improving the efficiency of water sample collection, and thus improving the practicality of the equipment.

[0027] 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. 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 protection scope of the present utility model.

[0028] Please see Figure 1-5This utility model provides a technical solution: a controllable water sample collection device, including a housing 1, a drive motor 2 fixedly installed on the inner wall of the housing 1, a threaded rod 8 fixedly installed on the output end of the drive motor 2, one end of the threaded rod 8 extending into the interior of the housing 1 and rotatably connected to the inner wall of the bottom surface of the housing 1, a threaded plate 3 threadedly installed on the outer surface of the threaded rod 8, one end of the threaded plate 3 extending to the outside of the side wall of the housing 1, a movable plate 4 slidably installed on the outer wall of the threaded plate 3, a sampling tube 5 provided at one end of the movable plate 4, a filter assembly 6 provided on the lower surface of the sampling tube 5, and an adjustment assembly 7 provided on the side wall of the housing 1;

[0029] The filter assembly 6 includes a connecting frame 61 and a connecting rod 66. A compression spring 64 is fixedly installed on the lower surface of the connecting frame 61. A support block 63 is fixedly installed on one end of the compression spring 64. A protective net 62 is fixedly installed on one end of the support block 63. A limit rod 65 is fixedly installed on the upper surface of the support block 63. One end of the limit rod 65 passes through the interior of the compression spring 64 and extends to the outside of the upper surface of the connecting frame 61. A baffle is fixedly installed on one end of the limit rod 65. The other end of the connecting rod 66 is fixedly connected to the lower surface of the sampling tube 5. A top block 67 is fixedly installed on one end of the connecting rod 66.

[0030] The specific implementation method is as follows: At this time, the drive motor 2 on the housing 1 is started. The drive motor 2 drives the threaded rod 8 to rotate. The threaded rod 8 drives the threaded plate 3 to move through the thread. The threaded plate 3 drives the moving plate 4 to move synchronously. At this time, the moving plate 4 will drive the limiting block 77 to move in the groove on the drive frame 73. The moving plate 4 will drive the sampling tube 5 to move into the water. The sampling tube 5 drives the connecting rod 66 to move synchronously. The connecting rod 66 drives the top block 67 to move into the protective net 62. When the top block 67 contacts the inner wall of the protective net 62, the top block 67 will be squeezed by the connecting rod 66 and will push against the protective net 62. The synchronous compression helps to separate the sampling tube 5 from the protective net 62 when it is retracted. At this time, the protective net 62 will drive the support blocks 63 on both sides to move synchronously. The support blocks 63 on both sides will drive the corresponding limit rods 65 to slide on the connecting frame 61. The limit rods 65 will drive the baffle to move synchronously, which helps to keep the protective net 62 and the sampling tube 5 moving in the same direction. At the same time, the support blocks 63 on both sides will stretch the compression springs 64 on the connecting frame 61. At this time, the sampling tube 5 drives the protective net 62 to enter the water synchronously, and then the water collected by the sampling tube 5 is filtered through the protective net 62.

[0031] The adjusting assembly 7 includes a fixed sleeve 71, one end of which is fixedly connected to the side wall of the housing 1. A positioning hole is provided on the side wall of the fixed sleeve 71. A movable sleeve 72 is slidably mounted on the outer wall of the fixed sleeve 71. One end of the movable sleeve 72 is fixedly connected to the side wall of the connecting frame 61. A drive frame 73 is fixedly mounted on the outer wall of the movable sleeve 72. A telescopic spring 74 is fixedly mounted on the side wall of the drive frame 73. A paddle 76 is fixedly mounted on one end of the telescopic spring 74. A positioning rod 75 is fixedly mounted on the side wall of the paddle 76. One end of the positioning rod 75 passes through the interior of the telescopic spring 74 and extends into the positioning hole of the fixed sleeve 71. The other side wall of the drive frame 73 is slidably connected to the outer wall of the movable plate 4. A limit block 77 is fixedly mounted on the side wall of the movable plate 4. A groove is provided on the side wall of the drive frame 73. One end of the limit block 77 extends outside the groove of the drive frame 73.

[0032] The specific implementation method is as follows: When water samples need to be taken for testing, first adjust the distance of the sampling tube 5 on the moving plate 4 according to the required sampling position. At this time, pull the lever 76 to one side. The lever 76 pulls the positioning rod 75 out of the positioning hole of the fixed sleeve 71. When the drive frame 73 moves, it will drive the moving plate 4 to move synchronously on the threaded plate 3 through the limit block 77, thereby making the moving plate 4 drive the sampling tube 5 to the appropriate position. At this time, release the lever 76. Then, under the elastic force of the telescopic spring 74, the telescopic spring 74 pulls the positioning rod 75 into the positioning hole of the fixed sleeve 71 through the lever 76, thereby keeping the moving sleeve 72 in a fixed state. At the same time, the moving sleeve 72 keeps the moving plate 4 and the sampling tube 5 in a stable state through the drive frame 73.

[0033] Working Principle: When water samples need to be collected for testing, first adjust the distance between the sampling tube 5 on the moving plate 4 and the sampling tube 5 according to the required sampling location. Then, pull the lever 76 to one side, which pulls the positioning rod 75 out of the positioning hole of the fixed sleeve 71. At this time, the lever 76 will stretch the telescopic spring 74. Then, pull the drive frame 73 to one side to a suitable distance. The drive frame 73 will drive the moving sleeve 72 to move on the fixed sleeve 71. When the drive frame 73 moves, it will drive the moving plate 4 to move synchronously on the threaded plate 3 through the limit block 77, thereby moving the sampling tube 5 to the appropriate position. Then, release the lever 76. At this time, under the elastic force of the telescopic spring 74, the telescopic spring 74 will pull the positioning rod 75 into the positioning hole of the fixed sleeve 71 through the lever 76, thereby keeping the moving sleeve 72 in a fixed state. At the same time, the moving sleeve 72 keeps the moving plate 4 and the sampling tube 5 in a stable state through the drive frame 73. At this time, start the drive motor on the housing 1. 2. The drive motor 2 drives the threaded rod 8 to rotate. The threaded rod 8 drives the threaded plate 3 to move through the thread. The threaded plate 3 drives the moving plate 4 to move synchronously. At this time, the moving plate 4 will drive the limiting block 77 to move in the groove on the drive frame 73. The moving plate 4 will drive the sampling tube 5 to move into the water. The sampling tube 5 drives the connecting rod 66 to move synchronously. The connecting rod 66 drives the top block 67 to move into the protective net 62. When the top block 67 contacts the inner wall of the protective net 62, the top block 67 will be squeezed by the connecting rod 66 and will squeeze the protective net 62 synchronously. At this time, the protective net 62 will drive the support blocks 63 on both sides to move synchronously. The support blocks 63 on both sides will drive the corresponding limiting rods 65 to slide on the connecting frame 61. The limiting rods 65 drive the baffle to move synchronously. At the same time, the support blocks 63 on both sides will stretch the compression spring 64 on the connecting frame 61. At this time, the sampling tube 5 drives the protective net 62 to enter the water synchronously, and then the water collected by the sampling tube 5 is filtered through the protective net 62.

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.
