Description

Technical Field

[0001] This utility model relates to the field of groundwater exploration technology, specifically a portable penetration water sampling device for groundwater exploration. Background Technology

[0002] Groundwater resources are one of the most important water sources for human survival, widely used in agricultural irrigation, industrial production, and urban water supply. Therefore, groundwater exploration and monitoring are of paramount importance. Groundwater exploration typically involves measuring parameters such as water level, aquifers, permeability, and water quality, providing crucial information for water resource management, environmental protection, and hydrogeological research. However, groundwater exploration work often faces numerous challenges, especially in the selection and use of water intake equipment.

[0003] In traditional groundwater exploration, water sampling is a crucial step. Accurate sampling and subsequent analysis are essential; therefore, the design and performance of sampling equipment directly affect the reliability and accuracy of the exploration results. Especially for some inaccessible groundwater layers, existing groundwater sampling devices often suffer from problems such as complex structure, cumbersome operation, and heavy weight. These issues not only increase the difficulty of on-site operations but also easily lead to sample contamination or inaccurate sampling, ultimately affecting the effectiveness of groundwater exploration.

[0004] The shortcomings of existing technology:

[0005] Currently available groundwater intrusion sampling devices still have some shortcomings. First, many traditional sampling devices are complex in structure and large in size, making them inconvenient to carry, especially in field surveys. Heavy equipment not only increases transportation costs but also increases the labor intensity of operators. Some existing devices cannot provide sufficiently accurate water sample collection control, particularly in effectively regulating the inflow and outflow of water during sampling, which may lead to inaccurate water sample collection and even interfere with water quality analysis results.

[0006] In addition, many existing devices are poorly adapted to groundwater layers, especially when deep water extraction is required or when facing different groundwater layers. The stability and operational flexibility of the equipment are insufficient, and they cannot effectively meet the needs of on-site investigation. Utility Model Content

[0029] Please see Figure 1-4 A portable penetration sampling device for groundwater exploration is designed with portability, compact structure, and accuracy and reliability in the water sampling process. The device mainly includes core components such as a probe column 1, a corrugated pipe 2, a bottom cover 3, a stepping cylinder 4, a liquid inlet 31, a one-way valve 5, and a suspension rope 6.

[0030] The lowering column 1, as the main body of the entire device, is made of high-strength, corrosion-resistant materials such as stainless steel or composite materials to ensure it can withstand long-term use in groundwater environments without damage. Its inner diameter is rationally designed to accommodate the stepping cylinder 4 and related components, providing good structural stability. The lower end of the column connects to the bellows 2. The outer surface of the lowering column 1 is equipped with a spiral binding groove 11 for easy securing of the suspension rope 6, preventing it from slipping off during transport. Furthermore, a hanging ear 7 is installed at the top of the lowering column. This hanging ear is designed with a reinforced structure to withstand significant tensile force, ensuring the equipment can be safely suspended and lowered, preventing operational accidents caused by instability.

[0031] The corrugated pipe 2 is a key component of this device, serving as the primary container for water sample collection. Designed with an expandable and contractible corrugated structure, its volume can be altered by a cylinder, thus regulating the water collection rate. The bottom of the corrugated pipe is sealed with a bottom cap 3 to prevent water sample loss. Highly elastic materials are used in the corrugated pipe design to ensure it will not age or break even after repeated expansion and contraction. The upper end of the corrugated pipe is screwed to the lower probe 1, ensuring a secure connection and preventing loosening due to water pressure or external forces. The outer surface of the corrugated pipe can be coated with a wear-resistant material to enhance its durability and corrosion resistance during repeated underground use.

[0032] The bottom cap 3 seals the bottom of the bellows, allowing water samples to flow through the inlet holes 31. Four inlet holes 31 are provided on the bottom cap. When the stepping cylinder 4 pushes the bottom cap 3 away from the lower end face of the probe column 1, the bellows 2 expands, creating a negative pressure inside. At this point, external water is drawn in through the four inlet holes 31. A one-way valve 5 is installed at the upper end of each inlet hole 31, ensuring that water only enters the bellows 2 from the outside during water sample collection, preventing sampled water from flowing out.

[0033] Each inlet port 31 is equipped with a one-way valve 5, which is designed to ensure that water flows in only one direction. In this device, the one-way valve ensures that water can only enter the bellows from the outside and will not flow back to the external environment from inside the bellows.

[0034] The stepping cylinder 4 is the power source of this device. It mainly drives the bottom cap 3 to move up and down by changing the gas pressure inside the cylinder, thereby changing the internal space of the bellows 2 and thus realizing the liquid sampling operation. Through a precise control system, the stepping cylinder can achieve precise step adjustment, thereby precisely controlling the expansion and contraction of the bellows to complete the water sample collection.

[0035] The suspension rope 6 is a crucial component for the device's hoisting and descent. Made of high-strength materials such as Kevlar fiber or steel wire rope, it possesses extremely high tensile strength and abrasion resistance, ensuring it will not be damaged during prolonged use in groundwater. One end of the suspension rope 6 is connected to the mounting lug 7 of the descent column via a lifting ring 62, while the other end is fixed with a grip ring 61. Operators can easily manipulate the equipment to collect water samples or remove the device using the grip ring. In actual use, the suspension rope 6 allows for flexible adjustment of the device's vertical movement, enabling it to smoothly pass through water layers and reach the groundwater level for water sampling.

[0036] Applications and functions:

[0037] The primary function of this device is to collect groundwater samples, particularly suitable for water quality testing and hydrological analysis during groundwater exploration. By precisely controlling the inner volume of the bellows 2 using a stepping cylinder 4, a stable amount of water sample can be collected at the groundwater level, thereby improving the efficiency and accuracy of the collection process. The device's design allows for rapid and effective water sample collection without disturbing groundwater flow and prevents interference from any external contaminants. Its portability and ease of operation make it ideal for field or inaccessible groundwater exploration sites, and its robust structure and high-quality materials ensure that the device can withstand the demands of various underground environments.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
