Detailed Implementation

[0019] To better understand the technical content of this utility model, specific embodiments are described below in conjunction with the accompanying drawings. Various aspects of this utility model are described in this disclosure with reference to the accompanying drawings, which illustrate numerous illustrative embodiments. The embodiments of this disclosure are not necessarily defined to include all aspects of this utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in this utility model are not limited to any particular implementation. Furthermore, some aspects of this utility model can be used alone or in any suitable combination with other aspects disclosed in this utility model.

[0020] Example 1

[0021] like Figs. 1-3 As shown, this is the first embodiment of the present invention. This embodiment provides an intelligent stratified water quality sampler, including a main frame assembly 1, including a hexagonal bracket 11 for providing support, and sampling tubes 12 fixed to the hexagonal bracket 11. The number of sampling tubes 12 is set to eight, arranged in parallel inside the hexagonal bracket 11. The sampling cluster unit 2 includes a valveless water inlet 21 for water intake, a storage bottle 22 for providing storage space, a sealing membrane 23 for providing a seal, and a water pressure-spring puncture needle 24 for piercing the sealing membrane 23. The mechanical control assembly 3 includes a mechanical positioning encoder disk 31 for water depth positioning and a density float group 32 for density compensation.

[0022] like Figs. 1-3 As shown, the storage bottle 22 is pre-vacuumed to create negative pressure inside. When the sampler reaches the predetermined sampling water layer, the sampling cluster unit 2 starts working. The valveless inlet 21 allows water to flow in naturally. Since there is no valve obstruction, the water flow can enter the sampler more smoothly, reducing the errors and interference that may be caused by valve opening and closing, and ensuring the authenticity and accuracy of water sample collection. When water flows into the valveless inlet 21 and generates a certain water pressure, the water pressure-spring puncture needle 24 will move downward under the combined action of water pressure and spring, piercing the sealing membrane 23. The water body enters the storage bottle 22 directly under the action of negative pressure, completing the water sample collection process. The sampling trigger adopts a water pressure-spring linkage control mechanism. When the device dives to the target depth, it relies on the negative pressure difference to complete the self-priming sampling. This sampling method can preserve the original state of the water body and will not destroy the original distribution of suspended solids in the water body, thereby ensuring the effectiveness and accuracy of monitoring key indicators such as turbidity and total phosphorus.

[0023] Example 2

[0024] Reference Figs. 1-3This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, the sampling tube 12 includes an outer shell 121 and an inner liner 122. The inner liner 122 is fixed to the inner cavity of the outer shell 121. An inert gas, namely argon, is added to the hollow layer between the outer shell 121 and the inner liner 122.

[0026] The density float assembly 32 is fixed to the bottom of the hexagonal bracket 11, and the mechanical positioning encoder 31 is fixed to one side of the hexagonal bracket 11. The mechanical positioning encoder 31 has three standard positions: red, blue and yellow.

[0027] The sealing membrane 23 is located at the mouth of the storage bottle 22, the storage bottle 22 is fixed below the valveless water inlet 21, and the water pressure-spring puncture needle 24 is fixed above the valveless water inlet 21.

[0028] Storage bottle 22 is a 250ml borosilicate glass bottle, valveless inlet 21 has a diameter of 15mm, and sampling tubes 12 have a tube spacing of 20mm.

[0029] The density float group 32 consists of three sets of ceramic floats with different specific gravities, and can be configured with 0.8 g / cm³. 3 1.0g / cm 3 and 1.2g / cm 3 The hexagonal bracket 11 is made of titanium alloy.

[0030] like Figs. 1-3 As shown, a mechanical control component 3 is used, which integrates a mechanical positioning encoder 31 and a density float group 32. The mechanical positioning encoder 31 has a preset standard locking position, which can be infinitely adjusted after being rotated to unlock. The density float group 32 contains ceramic floats with different specific gravities, which can offset depth drift. The entire depth control process does not require the participation of electronic components, avoiding the problems of long-term water corrosion of electronic components and the release of metal ions to contaminate the sample, thereby ensuring the accuracy of heavy metal detection data.

[0031] When in use, the boat arrives at the sampling point, and the handheld device is placed vertically. Before operation, the mechanical positioning encoder 31 is rotated counterclockwise to release the positioning lock. The red mark is aligned with the baseline to set the surface sampling mode. After the device is lowered vertically to the water surface, the density float group 32 is observed to keep the tube upright. When the depth reaches 0.5m, the water pressure-spring puncture needle 24 operates. The water pressure pushes the trigger piston to compress the energy storage spring, and the puncture needle instantly punctures the sealing membrane 23. The water flows directly into the storage bottle 22 under negative pressure. After the surface sampling is completed, the device continues to descend. The gear set of the mechanical positioning encoder 31 rotates automatically with the diving depth. For mid-level sampling, the blue mark trigger mechanism works when the half depth is reached. When sampling at a custom depth, the mechanical positioning encoder 31 is rotated to the target scale. During the device's descent, the density float group 32 automatically counteracts the effects of turbulence and triggers sampling when the set depth is reached.

[0032] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0033] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
