Description

Technical Field

[0001] This utility model relates to the field of water samplers, specifically a field water sampler designed to prevent clogging. Background Technology

[0002] The field water sampler is a water sampling device designed specifically for complex field water environments. It can accurately collect water samples in different scenarios. Its core advantage is that through a special structure, it can effectively prevent the pipeline and water inlet from being blocked by mud, sand and debris during collection, ensuring smooth sampling and water sample quality.

[0003] Existing technologies commonly use outdoor water sources containing high concentrations of silt, suspended algae, and debris. These impurities quickly adhere to the filter pores and gradually clog the filtration channels, leading to a sharp drop in water flow or even complete flow interruption, making continuous water sampling impossible. This situation forces the equipment to be frequently shut down for cleaning, ultimately resulting in a significant decrease in overall sampling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a field water sample collector that is resistant to clogging. It is equipped with a closed-loop backwashing system, which can complete internal cleaning without disassembling the equipment. It is convenient and efficient to operate. It adopts a staged filtration design, which can effectively distribute the filtration pressure and avoid a single filter layer bearing the entire filtration load, thereby slowing down the clogging speed of the overall filter pores and ensuring the long-term stable operation of the system. This invention solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A field water sample collection device for preventing blockage includes a collection container. A first connecting block is fixedly connected to the lower end of the collection container. An auxiliary bucket is threaded onto the lower end of the side wall of the first connecting block. A counterweight is slidably installed on the inner wall of the auxiliary bucket. A feed pipe is fixedly connected to the upper end of the collection container. A water purification mechanism is provided on one side of the feed pipe. Limiting rings are fixedly connected to both the upper and lower ends of the side wall of the collection container. Multiple support rods are fixedly connected to the side of the two limiting rings that are close to each other. A first connecting pipe is fixedly connected to both sides of the upper end of the limiting ring located at the upper end of the side wall of the collection container. An electric cylinder is fixedly connected to the inner wall of the first connecting pipe. A second connecting block is fixedly connected to the output end of the electric cylinder. A handle is fixedly connected to the upper ends of the two second connecting blocks.

[0007] Preferably, a secondary water tank is fixedly connected to one side of the feed pipe, a water pump is fixedly connected to the inner wall of the secondary water tank, a first slot is opened at the upper end of the secondary water tank, one end of a second connecting pipe is fixedly connected to the output end of the water pump, a nozzle is fixedly connected to the other end of the second connecting pipe, and the side wall of the second connecting pipe is located on the inner wall of the first slot.

[0008] It is worth noting that the water pump delivers water to the nozzles via a second connecting pipe, allowing direct flushing of the feed pipe and water purification mechanism, avoiding the hassle of manual cleaning and improving maintenance efficiency.

[0009] Preferably, the water purification mechanism includes a limiting tube fixed to the inner wall of the feed pipe inlet hole, a clamping block fixed to the inner wall of the limiting tube, two second slots on one side of the clamping block, filter blocks slidably installed on the inner walls of the two second slots, a third slot at the upper end of the limiting tube, a sliding block slidably installed on the side wall of the third slot, fixing blocks fixed to both sides of the sliding block and the limiting tube, and a fourth slot at the lower end of the limiting tube.

[0010] It is worth noting that the second slot of the clamping block allows the filter block to be slidably installed and removed. When the filter block is clogged or fails, it can be directly pulled out and replaced, avoiding the need to replace the entire water purification mechanism and reducing maintenance costs. The two filter blocks are limited by the connection between the sliding block and the limiting tube.

[0011] Preferably, the fourth slot is located between the two filter blocks, and the side wall of the second connecting pipe is in contact with the inner wall of the fourth slot.

[0012] It is worth noting that the inner wall of the fourth slot is equipped with a second connecting pipe, through which the water pumped by the water pump is transported to the nozzle.

[0013] Preferably, the nozzle is located inside the limiting tube, and the opening of the nozzle faces away from the filter block of the storage container.

[0014] It is worth noting that the two filter blocks, the one furthest from the collection container, is the preliminary purification filter block. During use, this filter block is easily clogged by impurities such as silt and algae in the water. Therefore, it can be backwashed through the nozzle to effectively alleviate the clogging problem of the preliminary purification filter block.

[0015] Preferably, multiple filter holes are provided on both sides of the auxiliary water tank.

[0016] It is worth noting that water flows through multiple filter holes into the secondary water tank, and the water pump flushes the filter blocks, which are located away from the collection pot, with water from the secondary water tank.

[0017] Preferably, a waterproof cap is fixed to the inner wall of the first connecting pipe, and a hole is opened through the upper end of the waterproof cap. The output end of the electric cylinder passes through the hole and is connected to the lower end of the second connecting block.

[0018] It is worth noting that the electric cylinder is protected by a waterproof cover, and the electric cylinder is also a submersible electric cylinder with good waterproof function to prevent water from entering and damaging the electric cylinder so that it cannot be used.

[0019] Preferably, the sliding block and the fixing block, which are fixed to both sides of the limiting tube, are connected by bolts.

[0020] It is worth noting that the limit tube and the sliding block are connected by bolts to fix the two filter blocks in the middle of the clamping block. The filter blocks can also be quickly replaced by unfastening the bolts.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model: By setting two filter blocks, with the filter block furthest away from the storage pot serving as the first filter device, when the filter block is blocked by mud or algae, water can flow into the auxiliary water tank through the filter holes on both sides of the auxiliary water tank, and then the water pump will flow to the nozzle through the second connecting pipe to backwash the blocked filter block, thereby removing the impurities blocked inside the filter holes and ensuring the smooth operation of water collection.

[0023] 2. The backwashing function can clean the clogged filter blocks in time, reduce manual intervention, improve sampling efficiency, and enable the collector to work continuously and stably in harsh field environments.

[0024] 3. During disassembly, simply remove the bolts on the inner wall of the fixing block to remove the sliding block from the top of the limiting tube. During installation, place the two filter blocks into the two second slots respectively, and then fix the sliding block to the limiting tube with bolts and fixing blocks. It is very quick and convenient. Attached Figure Description

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In field water quality monitoring, environmental surveys, and scientific research, obtaining accurate, uncontaminated, and representative water samples is fundamental for subsequent analysis. However, field water environments are complex, often containing impurities such as silt, fallen leaves, and plankton. Traditional water samplers are prone to pipe blockage during collection, affecting not only efficiency but also potentially distorting the collected samples and compromising the accuracy of subsequent analyses. To address this, a new anti-clogging field water sampler has been developed. Specifically designed for complex field water environments, it effectively solves the clogging problem of traditional samplers and plays an irreplaceable role in field water sampling.

[0033] From the perspective of its positioning and importance, the field water sampler with anti-clogging function is positioned as a professional water sampling device adapted to complex field aquatic environments. In environmental monitoring, as people increasingly value the ecological environment, the water quality of field water bodies, as an important component of the ecosystem, is being monitored more frequently. Accurate water sampling is the primary step in monitoring work. If the sampler becomes clogged, it will not only delay the monitoring progress but may also render the monitoring data unusable, failing to accurately reflect the true pollution situation of the water body, and thus affecting the formulation of environmental governance decisions. In scientific research fields, such as aquatic biology research and hydrological and water resource research, researchers need to collect field water samples continuously over a long period to analyze indicators such as chemical composition and biological communities. The anti-clogging sampler ensures the smooth progress of the sampling work, ensuring that the obtained water samples meet research requirements and providing strong support for the accuracy of research conclusions. Furthermore, in the emergency response to sudden water pollution incidents, rapid and accurate collection of polluted water samples is crucial. The anti-clogging sampler can efficiently collect water samples in complex polluted water bodies, buying valuable time for timely assessment of the pollution level and the development of emergency response plans.

[0034] Looking back at the development of anti-clogging water samplers in the field, early field water sampling relied mainly on manual collection using simple containers such as buckets and glass bottles. This method was not only labor-intensive but also unable to achieve precise, quantitative sampling, let alone provide anti-clogging functionality. With technological advancements, simple mechanical samplers emerged, such as manual water pump-type samplers. However, these samplers had narrow pipes, making them prone to clogging when encountering water with high levels of impurities. To address this clogging problem, researchers began improving the sampler's structure by installing a filter at the inlet to initially filter large particles of impurities. However, with traditional filters, impurities easily adhered to the screen during use, and the pores gradually became clogged over time, failing to fundamentally solve the problem. Later, through optimization of the filter structure and materials, a detachable and washable filter design was adopted, allowing staff to easily clean impurities from the screen. Simultaneously, some samplers added a backwashing function, using reverse water flow to flush the filter during sampling intervals, effectively removing deposits and further improving the anti-clogging effect. In recent years, with the development of intelligent technology, some field water sample collectors have begun to be equipped with sensors and intelligent control systems, which can monitor the working status of the collector in real time. When signs of blockage are detected in the pipeline, the backwashing function is automatically activated or an alarm signal is issued to remind staff to deal with it in time, which has significantly improved the anti-blockage capability and intelligence level of the collector.

[0035] In terms of function and design, field water samplers with anti-clogging features a variety of practical functions and a scientifically sound structural design. Their core function is anti-clogging. Besides installing a high-efficiency filter at the inlet, some samplers employ unique hydraulic designs that optimize the shape and size of the water flow channels to reduce eddies and stagnation within the channels, thus lowering the probability of impurities adhering to the pipe walls. Simultaneously, a backwashing function is a crucial guarantee against clogging. This function controls valves to change the water flow direction, using high-pressure water to flush the filter and pipes, removing adhering impurities and ensuring unobstructed water flow. Regarding water sample collection, the samplers can achieve fixed-point and quantitative sampling to meet various monitoring and research needs. Some samplers are equipped with adjustable sampling depth devices, allowing operators to flexibly adjust the sampling depth according to the water depth to obtain water samples from different water layers. In terms of design, the samplers typically use corrosion-resistant, high-strength materials such as stainless steel and engineering plastics, enabling them to adapt to harsh field environments, resist corrosion from chemicals in the water, and withstand external impacts, extending the sampler's service life. Furthermore, the collector's structural design prioritizes portability and ease of operation, with a lightweight overall design that allows staff to easily carry it to various field collection sites. The user interface is simple and clear, enabling staff to quickly master the operation even in complex field environments, thus improving collection efficiency.

[0036] The application scenarios for field water sample collection devices are very wide. In river and lake water quality monitoring, staff can carry the device to different monitoring sections to collect surface, middle, and bottom water samples, and analyze indicators such as dissolved oxygen, pH, chemical oxygen demand, and ammonia nitrogen to understand the water quality status and trends. In ecological surveys of reservoirs, ponds, and other water bodies, the device can be used to collect water samples to study the types and quantities of plankton, the growth status of aquatic plants, etc., providing data support for the protection and restoration of aquatic ecosystems. In marine environmental monitoring, for the complex aquatic environment of nearshore waters, the device can effectively filter impurities such as sediment and algae from seawater, collecting water samples that meet analytical requirements for monitoring indicators such as salinity, temperature, and heavy metal content, providing a basis for marine environmental protection and marine resource development. In groundwater monitoring, traditional water samplers are prone to clogging in wells with turbid water and high sediment content. However, field-based anti-clogging water samplers can successfully collect samples, helping monitoring personnel understand groundwater quality changes and ensuring the safe use of groundwater resources. Furthermore, in monitoring mine wastewater and industrial wastewater discharge outlets, the samplers can efficiently collect water samples from wastewater containing large amounts of suspended solids and impurities, providing accurate water sample data for wastewater treatment effectiveness assessment and environmental enforcement.

[0037] In practical applications, the anti-clogging water sampler has demonstrated outstanding performance, effectively solving the clogging problem of traditional samplers and significantly improving the efficiency and quality of field water sampling. In a water quality monitoring project in a river basin, when using traditional samplers, clogging occurred on average every 3-4 samples collected, with each clearing taking 10-15 minutes, severely impacting the monitoring progress. However, with the anti-clogging sampler, under the same water conditions, the sampler could continuously collect 10-15 samples without clogging. Even if minor clogging occasionally occurred, the backwashing function cleared it within 1-2 minutes, increasing sampling efficiency by 3-4 times. Furthermore, comparative analysis of the collected samples revealed significantly lower impurity content compared to those collected with traditional samplers, resulting in higher representativeness and accuracy, providing reliable data for subsequent water quality analysis. In the emergency response to a sudden water pollution incident, staff used a field water sampler with anti-clogging technology to quickly collect water samples from the polluted river. No clogging occurred during the collection process, and key indicator data of the polluted water samples were obtained in a timely manner. This provided crucial information for environmental protection departments to formulate emergency response plans and effectively controlled the spread of pollution. Furthermore, the durability of the field water sampler with anti-clogging technology has been verified in long-term field monitoring work. Its corrosion-resistant materials can withstand the erosion of harsh field environments, reducing equipment maintenance costs and replacement frequency, and providing strong support for the long-term stable operation of field water sampling.

[0038] To address the common problem in existing technologies where field water sources typically contain high concentrations of impurities such as silt, suspended algae, and debris, which rapidly adhere to the filter pores and gradually clog the filtration channels, leading to a sharp drop in water flow or even complete flow interruption and hindering continuous water sampling, thus requiring frequent equipment shutdowns for cleaning and ultimately causing a significant decrease in overall sampling efficiency, the following technical solution is provided.
