Description

Technical Field

[0001] This utility model relates to the field of water sampling and testing technology, specifically to a water stratification sampling and testing device. Background Technology

[0002] Water is indispensable to people's lives and production activities. In particular, the quality of drinking water is closely related to people's health. In order to strengthen the monitoring of water quality and keep abreast of the current water quality status, it is necessary to carry out a lot of on-site water sampling and other work to ensure the timeliness and accuracy of water quality data.

[0003] Because natural water bodies typically have a large three-dimensional structure, the characteristics of the water body vary at different locations. Therefore, to examine the true environment of a water body, it is necessary to set up multiple sampling points within the same water body. At the horizontal level, sampling points can be changed manually. However, at the vertical level, sampling equipment needs to be able to operate underwater in layers. Currently, stratified sampling devices for testing cannot automate the sampling process, requiring manual extraction, which is inconvenient. To address this issue, we provide a stratified water sampling and testing device. Utility Model Content

[0004] To address the problems in the existing technology, this utility model proposes a water stratification sampling and testing device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A water stratification sampling and testing device includes:

[0007] A handheld telescopic component, comprising a main sleeve and a secondary sleeve, wherein the secondary sleeve is telescopically fitted onto one end of the main sleeve;

[0008] The sampling pump is installed at the telescopic end of the auxiliary sleeve;

[0009] The sampling tube is detachably connected to the lower end of the sampling pump. The sampling tube is divided into multiple liquid storage chambers. Each liquid storage chamber has multiple corresponding area sampling holes on its inner front side. A layered shield is provided on the outside of the area sampling holes on the sampling tube. An extraction inner tube is provided inside the sampling tube. The extraction inner tube passes through the multiple liquid storage chambers and is sealed at the penetration point. The extraction inner tube located at the position of the multiple liquid storage chambers is provided with a hollow tube.

[0010] The main sleeve is equipped with a hand grip, which has a control button. The control button is electrically connected to the sampling pump and the stratification shield via a connecting wire.

[0011] As a further improvement to this solution, a motor is mounted on the main sleeve via a mounting bracket, and a lead screw is mounted inside the main sleeve via a bearing; a circular internal thread groove is opened inside the auxiliary sleeve, one end of the lead screw is located inside the auxiliary sleeve, and the other end of the lead screw is fixed with a helical gear II via a flat key; a helical gear I is fixed to the motor output shaft via a flat key, and helical gear I is located inside the main sleeve, with helical gear I and helical gear II meshing.

[0012] As a further improvement to this solution, the inner tube is a flexible tube, and a tube head is installed at the end of the inner tube. The tube head is installed outside the sampling tube; the tube head and the suction port of the sampling pump are connected by a connecting tube.

[0013] As a further improvement to this solution, the layered shielding device includes a shielding disc, a concave disc, and a telescopic cylinder. The lower end of the piston rod of the telescopic cylinder is provided with a concave disc, and the shielding disc is provided on the inner side of the concave disc. The telescopic cylinder is connected to the sampling tube, and the shielding disc shields the outside of the area sampling hole.

[0014] As a further improvement to this scheme, the sampling tube is a stainless steel hollow tube.

[0015] As a further improvement to this solution, the external connection discharge pipe of the sampling pump is used.

[0016] As a further improvement to this scheme, the area blocked by the blocking disk is larger than the sampling area of ​​the regional sampling hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This new model stabilizes the sampling device by using a hand grip, and the hand telescopic component sends the sampling tube into a predetermined depth through the telescopic structure of the main sleeve and the auxiliary sleeve. Then, the sampling pump and the stratification shield on the sampling tube are activated by the corresponding button on the hand grip. Water samples at different depths are collected into the storage tank through the area sampling hole. After sampling is completed, the sampling tube is disassembled and the sample is taken out. The entire sampling process is automated, and multiple water samples at different depths can be collected at one time, which is suitable for collecting complex stratified water samples.

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.

[0025] Example 1

[0026] like Figure 1-4 As shown in this embodiment, a water stratification sampling and testing device is provided, including a handheld telescopic component, a sampling pump, and a sampling tube.

[0027] The handheld telescopic component includes a main sleeve 1 and a secondary sleeve 2, with the secondary sleeve 2 telescopically fitted onto one end of the main sleeve 1. A sampling pump 3 is installed at the telescopic end of the secondary sleeve 2; the sampling pump 3 is externally connected to a discharge pipe.

[0028] The sampling tube 4 is detachably connected to the lower end of the sampling pump 3. The sampling tube 4 is a hollow stainless steel tube. The sampling tube 4 is divided into multiple liquid storage chambers. Each liquid storage chamber has multiple corresponding area sampling holes 40 on its inner front side. A layered shielding device 5 is provided on the outer side of the area sampling holes 40 on the sampling tube 4. An extraction inner tube 42 is provided inside the sampling tube 4. The extraction inner tube 42 passes through the multiple liquid storage chambers and is sealed at the penetration point. A perforated tube 43 is provided on the extraction inner tube 42 located at the position of the multiple liquid storage chambers.

[0030] The inner tube 42 is a flexible tube, and a tube head 41 is installed at the end of the inner tube 42. The tube head 41 is installed outside the sampling tube 4. The tube head 41 and the suction port of the sampling pump 3 are connected by a connecting tube 6.

[0031] The layered shielding device 5 includes a shielding disc 53, a concave disc 52, and a telescopic cylinder 51. The lower end of the piston rod of the telescopic cylinder 51 is provided with the concave disc 52, and the shielding disc 53 is provided on the inner side of the concave disc 52. The telescopic cylinder 51 is connected to the sampling tube 4, and the shielding disc 53 shields the outer side of the area sampling hole 40. The shielding area of ​​the shielding disc 51 is larger than the sampling area of ​​the area sampling hole 40.

[0032] During sampling, the staff holds the handheld handle 7 and activates the drive mechanism of the handheld telescopic component via control button 71. This causes the secondary sleeve 2 to extend forward within the main sleeve 1. Once the water depth reaches the preset scale, the corresponding button on control button 71 activates the telescopic cylinder 51 of the layered shielding device 5. The lower end of the piston rod of the telescopic cylinder 51 has a concave plate 52, which moves the shielding disc 53 upward. After the shielding disc 53 moves upward, the area sampling port 40 opens. Simultaneously, the sampling pump 3 is activated via control button 71. The suction port of the sampling pump 3 is connected to the inner extraction tube 42 via connecting pipe 6. A negative pressure is created inside the inner extraction tube 42, and the sampled water enters the storage tank through the perforated tube 43. After sampling is completed, the sampling tube 4 is removed from the bottom of the sampling pump 3 for collection and testing. This novel device stabilizes the sampling unit using a hand grip. The handheld telescopic component, through the telescopic structure of the main and auxiliary sleeves, inserts the sampling tube to a predetermined depth. Then, the sampling pump and the stratification shield on the sampling tube are activated by the corresponding button on the hand grip. Water samples at different depths are collected into the storage tank through the area sampling holes. After sampling is completed, the sampling tube is disassembled to retrieve the sample. The entire sampling process is automated and can collect multiple water samples at different depths at once, making it suitable for collecting complex stratified water samples.
