Description

Technical Field

[0001] This utility model belongs to the field of microbial sampling technology, specifically relating to an electromagnetic mechanical triggering surface water long-distance microbial sampling device. Background Technology

[0002] Traditional surface water microbial sampling methods include boat sampling, bridge-suspended rope sampling, and wading sampling. Boat and bridge-suspended rope sampling involve slowly lowering the sampler into the water, triggering a closure mechanism, and then retrieving it. Wading sampling is suitable for shallow rivers or shallow sampling points near the shore. Holding the bottle by the bottom, the stoppered bottle is inserted directly into the water, approximately 10-15 cm above the surface, with the bottle opening facing the water flow. The stopper is removed, allowing the sample to enter the bottle, which is then replaced with the stopper and removed from the water. For example, with traditional Van Dorn water samplers, sediment disturbance can increase turbidity by 30%-50% when sampling near the bottom, leading to a false increase of over 20% in the proportion of anaerobic bacteria in the microbial community.

[0003] Traditional samplers struggle to accurately reach target depths, especially in deep water where they easily disturb sediments, leading to a significant increase in turbidity of 30%-50%. This, in turn, distorts the microbial community structure, typically manifesting as an overestimation of the proportion of anaerobic bacteria by more than 20%. Meanwhile, reusable metal or glass samplers often suffer from cross-contamination due to incomplete sterilization or the introduction of exogenous microorganisms during manual operation. Furthermore, their inherent limitation of only being able to collect samples from a single point at a time fails to meet the demands of efficient, multi-point simultaneous sampling for stratified monitoring of large-scale water bodies, severely restricting the accuracy and timeliness of aquatic ecological research. Utility Model Content

[0004] The purpose of this invention is to provide an electromagnetic mechanical triggering surface water long-distance microbial sampling device to solve the problems mentioned in the background art, such as the difficulty of traditional samplers reaching the target depth, easy disturbance of sediment leading to microbial distortion, cross-contamination, low efficiency, and difficulty in meeting monitoring needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic mechanical triggering surface water long-distance microbial sampling device, including a hoisting assembly and a sampling assembly; a hydrological rope is connected to the sampling assembly, and the hydrological rope is connected to an external release and reeling device through the hoisting assembly. The release and reeling device releases and reels the hydrological rope, thereby adjusting the height of the sampling assembly to reach a specified position and depth.

[0006] The sampling device includes a mounting plate, on the surface of which a sampling bottle is mounted. A clamp is also installed on the mounting plate to secure the sampling bottle. The hydrological rope is fixed to the top of the mounting plate. An opening assembly is also provided on the mounting plate, positioned directly above the opening of the sampling bottle. An electrical wire is connected to the opening assembly, which is connected to an external power supply device. Power is supplied to the opening assembly, causing it to open the opening of the sampling bottle at a designated location, thereby drawing in water from the area for sampling. A pressure sensor is also installed on the mounting plate to detect the descent position.

[0007] Preferably, the opening component includes an electromagnetic push rod mounted on the mounting plate, which is connected to the wire. A pin is connected to the extended end of the electromagnetic push rod below the sampling bottle. The pin is positioned directly above the sampling bottle. When the electromagnetic push rod is energized, it extends and presses down on the pin, causing the pin to penetrate into the sampling bottle and opening the bottle. Under negative pressure, water at the location of the sampling bottle is drawn into the bottle.

[0008] Preferably, a limiting plate is also fixed on the surface of the mounting plate, the limiting plate is movably penetrated by the insertion pin, and a spring is also sleeved on the insertion pin. The insertion pin is T-shaped in general, and the two ends of the spring abut against the top T-shaped area of ​​the insertion pin and the top of the limiting plate, respectively. Through the compression and rebound of the spring, it can rebound synchronously when the electromagnetic push rod retracts, so as to separate the spring from the sampling bottle.

[0009] Preferably, the top of the sampling bottle is screwed with a cap, and a plastic sheet is provided in the middle of the cap. The needle is pressed down and penetrates the plastic sheet, thereby breaking the plastic sheet to allow subsequent water inflow.

[0010] Preferably, the sampling bottle is further provided with a closing barrel at the opening, and a connecting rod is fixedly provided on the bottom inner side of the bottle cap. The connecting rod passes through both ends of the closing barrel and is connected to it. A second spring is also sleeved on the connecting rod, which abuts against the connecting rod and the bottle cap. The bottom of the connecting rod has a protrusion, which limits the bottom end of the second spring, so that the second spring will not separate from the connecting rod. After the needle penetrates the plastic sheet, it will press down on the closing barrel, thereby forming a passage between the sampling bottle and the external water source. After the needle separates, the closing barrel will close the area where the plastic sheet was damaged under the rebound of the second spring, thus ensuring that the water source sampling is not contaminated.

[0011] Preferably, the bottom of the sampling bottle is open, and a PTFE filter membrane and a PVA water-soluble protective membrane are arranged sequentially from top to bottom on the inner side of the bottom of the sampling bottle. The PVA water-soluble protective membrane protects the PTFE filter membrane and begins to dissolve when it comes into contact with water. The function of the PTFE filter membrane is to expel the gas inside the sampling bottle under the pressure of the water source when water is injected into the sampling bottle, but not to expel the water source.

[0012] Preferably, the hoisting assembly includes a mechanical boom, and a pulley is installed at the end of the mechanical boom. The hydrological rope is connected to an external launching and retracting device via the pulley.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, a sampling component is mounted on a mechanical boom and positioned using a pressure sensor to achieve precise three-dimensional stratified sampling. At the same time, an electromagnetic and mechanical method is used to trigger the opening and closing mechanism, avoiding sediment disturbance and external pollution, thus greatly improving monitoring efficiency. This invention is suitable for microbial monitoring scenarios in rivers, lakes, and nearshore sea areas. Attached Figure Description

A hydrological rope 300 is fixed to the top of the mounting plate 100. An opening component is also disposed on the mounting plate 100, which is positioned directly above the opening of the sampling bottle 200. An electric wire 107 is connected to the opening component, which is connected to an external power supply device. The external power supply device provides power to the opening component, causing the opening component to open the opening of the sampling bottle 200 at a designated position, thereby drawing in water from the area for sampling. A pressure sensor 102 is also installed on the mounting plate 100 to detect the descent position.

[0027] In this embodiment, preferably, the opening component includes an electromagnetic push rod 104 mounted on the mounting plate 100. The electromagnetic push rod 104 is connected to the wire 107. A pin 106 is connected to the extended end below the electromagnetic push rod 104. The pin 106 is located directly above the sampling bottle 200. When the electromagnetic push rod 104 is energized, it extends and presses down the pin 106, causing the pin 106 to penetrate into the sampling bottle 200, thus opening the opening of the sampling bottle 200. Under negative pressure, the water source at the location of the sampling bottle 200 is drawn into the sampling bottle 200.

[0028] In this embodiment, preferably, a limiting plate 103 is also fixed on the surface of the mounting plate 100. The limiting plate 103 is movably penetrated by the insertion pin 106. A spring 105 is also sleeved on the insertion pin 106. The insertion pin 106 is T-shaped. The two ends of the spring 105 abut against the top T-shaped area of ​​the insertion pin 106 and the top of the limiting plate 103, respectively. Through the compression and rebound of the spring 105, it can rebound synchronously when the electromagnetic push rod 104 retracts, thereby realizing the separation of the spring 105 from the sampling bottle 200.

[0029] In this embodiment, preferably, a bottle cap 201 is screwed into the top of the sampling bottle 200, and a plastic sheet 204 is provided in the middle of the bottle cap 201.

The second spring 206 abuts against the connecting rod 207 and the bottle cap 201. A protrusion is formed at the bottom of the connecting rod 207. The bottom end of the second spring 206 is limited by the protrusion, so that the second spring 206 will not separate from the connecting rod 207. After the needle 106 passes through the plastic sheet 204, it will press down on the closed barrel 205, thereby forming a passage between the sampling bottle 200 and the external water source. After the needle 106 separates, the closed barrel 205 will close the area of ​​the plastic sheet 204 that was damaged under the rebound of the second spring 206, thereby ensuring that the water source sampling is not contaminated.

[0031] In this embodiment, preferably, the bottom of the sampling bottle 200 is open, and a PTFE filter membrane 202 and a PVA water-soluble protective membrane 203 are arranged sequentially from top to bottom on the inner side of the bottom of the sampling bottle 200. The PVA water-soluble protective membrane 203 protects the PTFE filter membrane 202 and begins to dissolve when it comes into contact with water. The function of the PTFE filter membrane 202 is to expel the gas inside the sampling bottle 200 under the pressure of the water source when water is injected into the sampling bottle 200, but not to expel the water source.
