Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampler technology, and more specifically to a sampler for outdoor environmental assessment. Background Technology
[0002] Outdoor environmental assessment refers to the comprehensive testing and evaluation of the outdoor environment to understand its quality, safety, and sustainability. Outdoor environmental assessment includes water quality testing, which detects the types, concentrations, and trends of pollutants in water bodies to assess water quality. Currently, water quality assessment typically requires the use of samplers to collect water samples.
[0003] Existing samplers can typically only collect water samples from one depth per use. If it is necessary to collect water samples from different depths in rivers, lakes, or other bodies of water, the sampler needs to be placed in the water multiple times for repeated sampling. This method is cumbersome and inefficient and needs to be improved. Utility Model Content

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The sampler for outdoor environmental assessment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example 1:
[0022] like Figure 1-5 As shown, a sampler for outdoor environmental assessment includes a sampler body 1. Multiple liquid storage chambers 7 are evenly distributed around the perimeter of the sampler body 1. Multiple water inlets 66 are located at the bottom of the sampler body 1, with their tops communicating with the interiors of the liquid storage chambers 7. Multiple sealing plugs 65 are located at the bottom of the sampler body 1, with their tops inserted into the interiors of the water inlets 66. Each sealing plug 65 has a sealing sleeve on its outer surface. A connecting plate 64 is fixedly connected to one side of each sealing plug 65. Multiple connecting rods 6 are located around the perimeter of the sampler body 1. Each connecting rod 6 has a hexagonal cross-section and its bottom is fixed... A connecting plate 64 is connected to the sampler body 1. A spring 63 is movably sleeved on the lower part of the outer wall of the multiple connecting rods 6. A number of limiting blocks 62 are fixedly connected to the upper part of the outer wall of the sampler body 1. The outer wall of the connecting rod 6 is slidably sleeved inside the limiting block 62. The top end of the spring 63 is fixedly connected to the bottom of the limiting block 62. The bottom end of the spring 63 is fixedly connected to the top of the connecting plate 64. A fixing frame 4 is fixedly connected to the middle of the top of the sampler body 1. The outer walls of the sampler body 1 and the fixing frame 4 are both provided with scale markings 5. A limiting plate 3 is fixedly connected to the top of the fixing frame 4. A handle 2 is fixedly connected to the middle of the top of the limiting plate 3. The upper part of the outer wall of the multiple connecting rods 6 is slidably sleeved around the inside of the limiting plate 3. A pressure plate 61 is fixedly connected to the top of the multiple connecting rods 6.
[0023] In this embodiment, the handle 2 facilitates user operation by holding the device, and the scale markings 5 allow staff to observe the depth of the sampler body 1 in the water, facilitating sampling at different water depths. During water sampling, the pressure plate 61, connecting rod 6, limiting block 62, spring 63, and connecting plate 64 work together to move the sealing plug 65, allowing the inlet 66 to be opened or closed, enabling water to enter the storage chamber 7 for sampling. The sampler body 1 can also be moved to different depths of water, and different water depths can be sampled using the same method. The pressure plate 61, connecting rod 6, limiting block 62, spring 63, and connecting plate 64 are all rust-proofed or made of corrosion-resistant materials.
[0024] Example 2:
[0025] like Figure 1-5 As shown, multiple vents 8 are provided around the top of the sampler body 1. The bottom of the multiple vents 8 is connected to the top of multiple liquid storage chambers 7. One-way vent valves 81 are fixedly installed inside the multiple vents 8. The top of the one-way vent valve 81 is the one-way venting end, and the bottom of the one-way vent valve 81 is the one-way inlet end. Multiple filters 82 are fixedly connected around the top of the sampler body 1. The multiple filters 82 are located above the multiple vents 8.
[0026] In this embodiment, the filter screen 82 facilitates filtration above the exhaust port 8, preventing impurities in the water from adhering to the exhaust end of the one-way exhaust valve 81. When sampling the water, the air inside the storage chamber 7 can be discharged through the one-way exhaust valve 81. The formula for calculating the critical depth of one-way exhaust valve 81 in water is as follows: If the air pressure inside the storage chamber 7 is normal pressure (0.1 MPa) and the opening pressure of the one-way exhaust valve 81 is 0.02 MPa, then the critical depth is:
[0027]
[0028] When the water depth is ≤8 meters, air can be naturally discharged through the one-way exhaust valve 81. Therefore, this device is suitable for water sampling with a water depth of ≤8 meters, and can also be adjusted according to the air pressure inside the liquid storage chamber 7 and the opening pressure of the one-way exhaust valve 81.
[0029] In summary, as Figure 1-5As shown, this sampler for outdoor environmental assessment allows the operator to hold handle 2 and vertically place the sampler body 1 in the water. The operator can then observe the scale markings 5 on the water surface to determine the depth of the sampler body 1. During sampling, the operator presses down on one of the pressure plates 61 and the connecting rod 6. The bottom of the connecting rod 6 extends through the connecting plate 64, stretching the bottom of the spring 63. The connecting plate 64 then moves the sealing plug 65 downwards, disengaging it from the inlet 66. This opens the inlet 66, allowing water to enter the storage chamber 7. Air inside the storage chamber 7 can be released through a one-way exhaust system. After the valve 81 is discharged and the sample is taken, the pressure plate 61 and the connecting rod 6 are released. The elasticity of the spring 63 drives the connecting plate 64, the sealing plug 65 and the connecting rod 6 to move upward to reset. If necessary, the connecting rod 6 can also be moved upward manually so that the top of the sealing plug 65 is fully inserted into the inlet 66 to seal and close the water, thus storing the water. If it is necessary to sample water at different levels, the sampler body 1 can be moved to water at different depths and other inlets 66 can be opened or closed in the same way. This allows water at different levels to enter multiple storage chambers 7 for storage, making it convenient to collect water at different levels at a time. After sampling, the sampler is slowly lifted.
