Abstract
Description
Technical Field
[0001] This utility model relates to the field of water quality environmental protection testing and sampling technology, specifically a sampling device for water quality environmental protection testing. Background Technology
[0002] Water is the source of life and a crucial component of ecosystems; its quality directly impacts human health and ecological balance. With rapid industrialization and urbanization, large amounts of industrial wastewater, domestic sewage, and agricultural non-point source pollutants are discharged into water bodies, exacerbating water quality deterioration. Against this backdrop, accurate and efficient water quality testing has become essential for ensuring water environmental safety. However, traditional water sampling methods and equipment have many drawbacks. Simple manual sampling methods struggle to collect samples from different depths and areas, resulting in samples lacking representativeness and failing to accurately reflect the overall condition of the water body.
[0003] According to the description in the patent announcement (CN215374645U) of a water quality sampling device for environmental protection testing, the device includes a "base plate, casters, and water collection tank" to perform sampling.
[0004] Regarding the above description, the applicant believes the following issues exist:
[0005] The water sampling device used for environmental monitoring utilizes a base plate, casters, and a water collection tank to perform sampling. However, the process involves manually removing the sampling device, activating a hydraulic rod to extend the second suction pipe through a connecting plate, and then manually inserting the second suction pipe into the water. This manual operation affects the safety and convenience of sampling and makes it impossible to classify and store water samples from different locations, impacting the accuracy of subsequent testing. Therefore, improvements to this device are necessary. Utility Model Content

A connecting shaft 38 is fixedly connected to the bottom right side. A sampling bucket 39 is fixedly connected to the inside of the connecting shaft 38. A filter frame 391 is fixedly connected to the inside of the sampling bucket 39. A flexible hose 392 is fixedly connected to the rear side of the sampling bucket 39. A connecting frame 393 is slidably connected to the outside of the flexible hose 392. The connecting frame 393 is fixedly connected to the top of the support platform 33. A two-way pipe 394 is fixedly connected to the left side of the flexible hose 392. A water pump 395 is fixedly connected to the outside of the two-way pipe 394. A fixing frame 396 is fixedly connected to the outside of the two-way pipe 394.
[0031] The rotating rod 32 is rotatably connected to the inside of the sampling device body 1, and the support platform 33 is rotatably connected to the top of the sampling device body 1, so that the support platform 33 can be rotated under the action of the rotating rod 32. The bottom of the first threaded rod 35 is rotatably connected to the bottom of the fixed frame 34, and the support frame 37 is slidably connected to the inside of the fixed frame 34, so that the support frame 37 and the connecting shaft 38 can be moved under the action of the first threaded rod 35. The water pump 395 and the fixed frame 396 are respectively fixedly connected to the top of the support platform 33, and the fixed frame 396 is L-shaped, so that the sampled water can be transported to the storage tank 55 for storage under the action of the water pump 395.
[0032] Example 2
[0033] Please see Figure 1-5 Furthermore, based on Embodiment 1, the storage mechanism 5 further includes a second threaded rod 52, which is rotatably connected to the inside of the sampling device body 1. A knob 51 is fixedly connected to the left side of the second threaded rod 52, and a movable frame 53 is threadedly connected to the outer periphery of the second threaded rod 52. The movable frame 53 is slidably connected to the top of the sampling device body 1, and a clamping plate 54 is fixedly connected to the right side of the movable frame 53. A storage tank 55 is provided inside the clamping plate 54 and is located on the left side of the protective plate 4. A sealing cap 56 is threadedly connected to the top of the storage tank 55.
[0034] The inner side of the clamping plate 54 is in contact with the outer side of the storage tank 55, and the outer side of the storage tank 55 is in contact with the left side of the protective plate 4. The storage tank 55 is slidably connected to the top of the sampling device body 1, and the storage tank 55 is located at the bottom left end of the two-way pipe 394, which facilitates the fixing of the storage tank 55 under the action of the clamping plate 54 and the protective plate 4. A sliding groove is provided on the top of the sampling device body 1, and the moving frame 53 is slidably connected in the sliding groove, which facilitates the more stable movement of the moving frame 53 under the action of the sliding groove.
[0035] In actual operation, when this device is used, when sampling is required in water quality environmental protection testing, firstly, the three storage tanks 55 are slidably connected to the top of the sampling device body 1 and in contact with the left side of the protective plate 4. By turning the second threaded rod 52 through the knob 51, the position of the moving frame 53 and the clamping plate 54 is adjusted so that the inner side of the clamping plate 54 is in contact with the outer side of the storage tank 55, which facilitates fixing the storage tank 55. The protective plate 4 not only prevents the storage tank 55 from accidentally tipping over, but also provides protection for it, and opens the sealing cover 56.
[0036] Simultaneously, the sampling device body 1 is moved to the vicinity of the water source to be sampled by the handrail 6 and the caster 2. The staff can lock the caster 2 by holding the handrail 6 and the self-locking structure of the caster 2 to ensure the stability of the sampling device body 1 during operation. The second servo motor 36 drives the first threaded rod 35 to rotate, controlling the lifting of the load-bearing frame 37 and the sampling bucket 39 to meet the water sample collection needs at different depths. At the same time, the first servo motor 31 drives the rotating rod 32 and the load-bearing platform 33 to rotate, so that the sampling bucket 39 can be easily adjusted to the required position to achieve multi-directional sampling.
[0037] The filter frame 391 performs preliminary filtration of the collected water sample to remove large particulate impurities and improve sample quality. When the sampled water is in the sampling bucket 39, the water source can be transported to the storage bucket 55 through the two-way pipe 394 for storage under the action of the water pump 395 and the hose 392. The bottom of the left end of the two-way pipe 394 should be at the top of the storage bucket 55. The three storage buckets 55 can classify and store water sources at different depths and positions, improving the standardization of subsequent test data.
[0038] When storage is complete, the sealing cap 56 on the top of the storage tank 55 effectively prevents water sample evaporation and external impurities from contaminating it, ensuring the integrity and accuracy of the water sample during storage and transportation. Excess water in the sampling tank 39 can be discharged through the bottom of the sampling tank 39.
