Description

Technical Field

[0001] This utility model relates to the field of water sample extraction technology, and in particular to a water sample pH detection sample extraction device. Background Technology

[0002] Water quality monitoring is a crucial step in evaluating water quality. It requires testing multiple indicators such as temperature, color, turbidity, and pH value. Among these, pH value is an important indicator reflecting the acidity or alkalinity of water. It is essential for understanding the properties of water bodies and assessing their impact on the ecological environment and human activities, and is widely used in environmental monitoring, industrial production, drinking water safety, and other fields.

[0003] When extracting water samples, select a calm water surface, place the extraction device in the water, pump water into the device, filter out the mud and impurities in the water, and finally collect the extracted water sample.

[0004] Existing water sample pH testing and extraction devices require operators to come into contact with the water during extraction. This can cause harm to the operator if the water is toxic or harmful. Therefore, a new water sample pH testing and extraction device is proposed. Utility Model Content

The coarse filter head can block impurities in the water. When the water is pumped into the filter box and comes into contact with the filter plate, the filter plate filters the sediment in the water, which has the function of quickly extracting water samples.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a water sample pH detection sample extraction device, including a support frame 1, an extraction mechanism 2 is provided on the top of the support frame 1, and a collection mechanism 3 is provided at the bottom of the extraction mechanism 2.

[0030] Extraction mechanism 2 includes a filter box 204 fixedly installed on the top of support frame 1. A filter plate 207 is movably installed inside the filter box 204. A three-ear slide plate 202 and a three-ear support plate 201 are respectively provided on the outer surface of support frame 1 from top to bottom. A lead screw 203 is installed at the center of the top of support frame 1. A telescopic tube 206 is provided on the top of the three-ear slide plate 202. One end of the telescopic tube 206 passes through the bottom of the three-ear slide plate 202 and a coarse filter head 208 is fixedly installed thereon.

[0031] Specifically, the three-ear support plate 201 is fixedly connected to the support frame 1, and the three-ear sliding plate 202 is slidably connected to the outside of the support frame 1 column. The center of the three-ear sliding plate 202 is movably installed on the outside of the lead screw 203 through a threaded collar. The bottom end of the lead screw 203 is movably installed on the top center of the three-ear support plate 201 through a bearing seat. When the lead screw 203 rotates, the three-ear sliding plate 202 is driven to move up and down on the outside of the support frame 1 column through the action of the threaded sleeve. During the up and down movement of the three-ear sliding plate 202, the coarse filter head 208 is driven to rise or fall to extract water at different depths. Under the action of the coarse filter head 208, larger impurities in the water are blocked.

[0032] Specifically, the outer surface of the lead screw 203 is movably mounted at the top center of the support frame 1 via a bearing, and the lead screw 203 extends through the filter box 204 to the outside. The top of the telescopic tube 206 is connected to the bottom of the filter box 204. The filter plate 207 is movably inserted into the inner cavity of the filter box 204. When the coarse filter head 208 is driven to move up and down, the water sample is continuously extracted by the telescopic tube 206 itself. Under the action of the filter plate 207, the sediment in the water is filtered to prevent the sediment from affecting the pH test results of the water sample.

[0033] Specifically, a battery compartment 205 is provided on one side of the filter box 204, and a discharge port 209 is provided on the other side of the filter box 204, which is connected to the filter box 204. A rotating handle 210 is installed at one end of the lead screw 203 extending to the outside of the filter box 204. A water pump adapted to the telescopic tube 206 is provided in the inner cavity of the filter box 204. The water pump is electrically connected to the battery compartment 205. Opening the discharge port 209 injects clean water into the filter box 204, which can discharge the mud and sand in the filter box 204 without affecting subsequent use.

[0034] Furthermore, the support frame 1 is placed in the water, and the water level must not be higher than the bottom of the disc of the support frame 1. The rotating handle 210 is manually rotated, and the rotating handle 210 drives the lead screw 203 to rotate on the three-ear support plate 201. The lead screw 203 drives the three-ear sliding plate 202 to move, and the three-ear sliding plate 202 drives the coarse filter head 208 to move, so that the telescopic tube 206 deforms accordingly. First, the coarse filter head 208 is placed at a certain depth, and the water pump in the inner cavity of the filter box 204 is controlled to run. With the assistance of the coarse filter head 208, water is pumped into the inner cavity of the filter box 204. When the water comes into contact with the filter plate 207, the mud and sand in the water are filtered. Finally, the water that has been treated is collected to complete the sampling.

[0035] Example 2

[0036] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The collection mechanism 3 includes a liquid outlet column 301 fixedly installed at the bottom of the filter box 204. The bottom of the filter box 204 is symmetrically provided with an L-shaped plate 302 adapted to the liquid outlet column 301. A sliding strip 304 is connected to one side of the L-shaped plate 302. A baffle 307 is installed inside the L-shaped plate 302.

[0037] Specifically, the liquid outlet column 301 is located in the middle of the opposite side of the two L-shaped plates 302. One side of the L-shaped plate 302 is provided with a sliding hole that is adapted to the stop block 307. The stop block 307 is movably installed inside the sliding hole, which locks the mouth of the water sample collection bag on the top of the two sliding strips 304 and pushes the water sample collection bag away from the stop block 307. Under the action of the two stop blocks 307, the stability of the water sample collection bag is ensured when extracting water samples.

[0038] Specifically, a rear baffle 303 is installed on one side of the L-shaped plate 302, a spring 305 is installed inside the L-shaped plate 302, a limit plate 306 is installed on one side of the spring 305, and a sliding groove adapted to the limit plate 306 is opened inside the L-shaped plate 302. The limit plate 306 is slidably connected inside the sliding groove. Under the action of the spring 305, an outward pushing force is applied to the limit plate 306, so that the stop block 307 obtains an outward pushing force. Under the action of the two stop blocks 307, the stability of the water sample collection bag is ensured when extracting water.

[0039] Furthermore, the opening of the water sample collection bag is secured to the top of the two sliding strips 304 and pushed so that the collection belt abuts against one side of the rear baffle 303. Under the action of the spring 305, the spring 305 pushes the limiting plate 306 outward, and the limiting plate 306 applies an outward pushing force to the stop block 307. Under the action of the two springs 305, the corresponding stop block 307 is secured to the outside of the collection belt. Finally, the water sample is introduced into the collection bag through the liquid outlet column 301.

[0040] Working principle: Place the support frame 1 in water, ensuring the water level is not higher than the bottom of the disc on the support frame 1. Manually rotate the handle 210. The handle 210 drives the lead screw 203 to rotate on the three-ear support plate 201. The lead screw 203 moves the three-ear sliding plate 202, which in turn moves the coarse filter head 208, causing the telescopic tube 206 to deform. Initially, the coarse filter head 208 is positioned at a certain depth. Control the water pump inside the filter box 204. This water pump is the same as existing ones and as those disclosed. With the assistance of the coarse filter head 208, water is pumped into the filter box 204. The water then contacts the filter plate 201. At 7 o'clock, the mud and sand in the water are filtered. Then, the mouth of the water sample collection bag is clamped on the top of the two sliding strips 304 and pushed so that the collection belt is against one side of the rear baffle 303. Under the action of the spring 305, the spring 305 pushes the limiting plate 306 outward. The limiting plate 306 applies an outward pushing force to the stop block 307. Under the action of the two springs 305, the corresponding stop block 307 is clamped on the outside of the collection belt. Finally, the water sample is introduced into the collection bag through the liquid outlet 301. After the device is used, the impurity discharge port 209 is opened and clean water is injected into the filter box 204 to discharge the mud and sand in the filter box 204.
