Description

Technical Field

[0001] This application relates to the field of groundwater vacuum sampling bottle technology, and more specifically, to a groundwater vacuum sampling bottle. Background Technology

[0002] Groundwater is a vital water resource in my country, particularly for coastal cities, inland cities, and large and medium-sized cities in the north. However, with the rapid increase in water demand for industrial, agricultural, and domestic production, and the year-on-year increase in wastewater discharge, the scarcity and pollution of groundwater in my country is becoming increasingly severe. Therefore, groundwater sampling is necessary.

[0003] In the field of groundwater monitoring and sampling, the sealing performance and ease of operation of sampling bottles directly affect the purity of samples and the reliability of data. Traditional groundwater sampling bottles mostly adopt mechanical seals or screw cap structures, which often have the following technical pain points during the sampling process: First, poor sealing can lead to the ingress of external air, surface pollutants, or microorganisms, causing cross-contamination of samples. Second, the sampling operation is complicated, and direct extraction is not possible; external equipment is required, resulting in poor convenience, especially in the field where fewer items need to be carried and greater convenience is required. Third, some sampling bottles lack vacuum retention capabilities. In addition, although there have been attempts at vacuum sampling bottles in existing technologies, they often suffer from problems such as complex structure, high cost, poor reusability, or short vacuum retention time, making it difficult to meet the requirements for rapid sampling in the field. Therefore, it is very important to have a vacuum sampling bottle that can meet the requirements simply by setting a connecting structure on the cap.

[0004] In view of this, we propose a groundwater vacuum sampling bottle. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a groundwater vacuum sampling bottle that solves the following technical problems in the traditional groundwater sampling bottles mentioned above, which mostly use mechanical seals or screw caps: First, inadequate sealing leads to the ingress of external air, surface pollutants, or microorganisms, causing cross-contamination of the sample. Second, the sampling operation is complex, as it cannot be directly extracted and requires external equipment, resulting in poor convenience, especially in the field where minimal equipment needs to be carried. Third, some sampling bottles lack vacuum retention functionality. Furthermore, although there have been attempts at vacuum sampling bottles in the prior art, they often suffer from complex structures, high costs, poor reusability, or short vacuum retention times, making it difficult to meet the technical requirements for rapid field sampling. This application achieves the desired technical effect.

[0034] Vacuum control assembly 3 includes a connecting pipe 31 connected to the outside of bottle cap 2, an installation pipe 32 provided on the outside of the connecting pipe 31, a threaded groove A33 opened inside the installation pipe 32, and the threaded groove A33 is threadedly connected to a threaded block A34 provided on the outer wall of the connecting pipe 31.

[0035] The outer end of the mounting tube 32 is connected to a control chamber 38. A sealing block 35 is rotatably installed inside the control chamber 38. The sealing block 35 is coaxially connected and fixed to the handle 36 provided on the outer side of the mounting tube 32.

[0036] A through hole 37 is opened in the middle of the sealing block 35.

[0037] A retaining ring 301 is fixedly installed on the outer wall of the connecting pipe 31, and a sealing ring is installed on the outside of the retaining ring 301. The mounting pipe 32 is pressed against the outer wall of the retaining ring 301.

[0038] Two facilitating blocks 3001 are symmetrically fixed on the outer wall of the sealing block 35, and the facilitating blocks 3001 are arranged in an arc structure;

[0039] The slidable block 3001 is slidably disposed inside the slidable groove 3002 opened on the inner wall of the control chamber 38;

[0040] The inner side of the motive block 3001 is connected to the inner wall of the motive groove 3002 by the spring 3003.

[0041] A connecting pipe 3200 is provided on the outside of the control compartment 38. One end of the connecting pipe 3200 is tapered, and the inner wall of the other end is provided with a threaded groove B3300. The threaded groove B3300 is threadedly connected to a threaded cylinder 3100 that is connected to one side of the control compartment 38. A sealing ring is provided on the contact surface of the threaded cylinder 3100 and the threaded groove B3300.

[0042] The symmetrical design of the vacuum control component 3, combined with the threaded connection structure of the connecting pipe 31 and the mounting pipe 32, and the sealing design of the retaining ring 301 and the sealing ring, effectively solves the problem of poor sealing and prevents the ingress of external air, pollutants, or microorganisms. The rotation of the sealing block 35 controls the on / off state, and the elastic sealing design of the facilitating block 3001 and the spring 3003 enables convenient vacuum extraction and sealing operations without the need for complex manual adjustments, improving operational efficiency. The vacuum bottle itself has adsorption force, adapting to the needs of rapid sampling in the field.

[0043] Working principle: Before sampling, the cap 2 of the groundwater vacuum sampling bottle is installed at the inlet of the sampling bottle body 1. Vacuum extraction and sealing operations are achieved through the vacuum control component 3. The threaded block A34 on the outer wall of the connecting pipe 31 is threadedly connected to the threaded groove A33 inside the installation pipe 32, tightly fixing the installation pipe 32 and the connecting pipe 31. At this time, the sealing ring on the outer wall of the retaining ring 301 is pressed against the inner wall of the installation pipe 32 to form a seal. Simultaneously, the threaded groove B3300 at the other end of the connecting pipe head 3200 is threadedly connected to the threaded cylinder 3100 on one side of the control chamber 38. When vacuuming is performed using the extraction device, rotating the handle 36 causes the sealing block 35 to rotate within the control chamber 38, causing the through hole 37 in the middle of the sealing block 35 to connect with the connecting pipe 31. One side of the connector 31 is open, while the other side is closed. At this time, it can be connected to an external vacuum device through the conical structure at one end of the connector head 3200 to extract air from the sampling bottle 1 to form a vacuum environment. After extraction, the handle 36 is rotated in the opposite direction to misalign the through hole 37 with the connecting pipe 31. The facilitating block 3001 on the outer wall of the sealing block 35 slides in the facilitating groove 3002 on the inner wall of the control chamber 38. The spring 3003 on the inner side of the facilitating block 3001 provides elastic force to hold it in place, so that the sealing block 35 fits tightly against the end of the mounting pipe 32 to form a reliable seal. When sampling, it can be directly collected through the connection structure of one of the vacuum control components 3 and the pipe contact collection point without the need for complicated external equipment. The operation is simple and efficient.
