Description

Technical Field

[0001] The utility model relates to the technical field of water environment treatment, and more specifically to a sample collection cylinder for water environment detection. Background Art

[0002] When detecting the content of water quality microorganisms in a lake, an inspector needs to use a collection cylinder to sample the water source in the lake. Since various waterweeds and sediment are mixed in the lake water, the traditional collection cylinder will collect the waterweeds and sediment together during the process of collecting the water source. Therefore, when the inspector fills and collects the collected water source, it is necessary to first filter the waterweeds and sediment mixed in the water source before the water source can be filled and sent back to the laboratory to avoid the detection accuracy from being affected by the sediment carried in the water source sample. Since the entire lake needs to be sampled at multiple points, the inspection personnel need to filter all the collected samples separately, which not only increases the workload of the staff but also reduces the water source collection efficiency. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a sample collection cylinder for water environment detection to solve the above problems.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A sample collection cylinder for water environment detection, comprising:

[0005] A cylinder body with a water storage cavity, and a water collection groove is opened at the top end of the cylinder body;

[0006] A spiral tube rotatably arranged in the water storage cavity and communicating with the water collection groove, and filter holes are arranged on the side wall of the spiral tube in an array along the spiral path;

[0007] A drain pipe fixedly installed at the bottom end of the cylinder body and communicating with the water storage cavity;

[0008] A counterweight block slidably arranged at the bottom end of the cylinder body and abutting against the top end of the drain pipe.

[0009] Preferably, a plug block is fixedly installed in the cylinder body, a collection groove is opened in the plug block, a spiral tube is movably connected in the collection groove, and symmetrically arranged waste material grooves are opened at the bottom end of the spiral tube, and the waste material grooves communicate with the collection groove.

[0010] Preferably, a sealing block is fixedly installed on the side wall of the cylinder body, and the side wall of the sealing block abuts against the inside of the collection groove.

[0011] Preferably, a motor is fixedly installed at the bottom end of the plug block, the output end of the motor is fixedly connected to the spiral tube, and balls are arranged on the side wall of the spiral tube in a circumferential array.

[0013] Preferably, a drainage chamber is arranged inside the cylinder body, the drainage chamber communicates with the through hole, and a drain pipe is movably connected inside the drainage chamber.

[0014] In the above technical solution, a sample collection cylinder for water environment detection provided by the present utility model has the following beneficial effects: when the cylinder body is placed in water, the cylinder body is pulled into the water by the configuration block installed at the bottom of the cylinder body, so that the water sample with sediment and water plants flows into the collection tank for collection. The collection tank is communicated with the spiral pipe through the threaded pipe, so that the water sample collected in the collection tank flows into the spiral pipe. When the water sample enters the spiral pipe, the spiral pipe is driven to rotate at a high speed, so that the water sample flows towards the water storage cavity along the filter holes formed on the side wall of the spiral pipe under the action of centrifugal force. The water plants mixed in the water sample are filtered through the filter holes, so that the water plants are separated from the water sample. And the sediment mixed in the water sample is filtered through the filter plate installed in the filter holes, so that the sediment in the water sample is separated and flows into the water storage cavity for storage. When the cylinder body is pulled onto the shore, by pushing the counterweight block upwards, the configuration block is separated from the port of the drain pipe, so that the water sample stored in the water storage cavity flows out along the drain pipe. It can not only automatically filter the water sample during the collection process, but also improve the collection efficiency of the inspectors, and avoid the time wasted by filtering the water sample separately.

[0021] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] As Figures 1-3 shown, a sample collection cylinder for water environment detection includes:

[0023] A cylinder body 1 provided with a water storage cavity 5, and a water collection groove 2 is opened at the top end of the cylinder body 1;

[0024] A spiral tube 6 rotatably arranged in the water storage cavity 5 and communicating with the water collection groove 2, and filter holes 7 are arranged on the side wall of the spiral tube 6 in an array along a spiral path;

[0025] A drain pipe 14 fixedly installed at the bottom end of the cylinder body 1 and communicating with the water storage cavity 5;

[0026] A counterweight 15 slidably arranged at the bottom end of the cylinder body 1 and abutting against the top end of the drain pipe 14.

[0027] Specifically, when the cylinder body 1 enters the water, gravity is provided to the cylinder body 1 by the counterweight 15, so that the cylinder body 1 sinks vertically, thereby avoiding tilting of the cylinder body 1 during sampling. And when the cylinder body 1 is submerged in the water surface, the water sample mixed with sediment and waterweeds flows into the water collection groove 2. Since the spiral tube 6 communicates with the water collection groove 2, the water sample flows into the spiral tube 6 along the water collection groove 2. By driving the spiral tube 6 to rotate, the centrifugal force generated by the spiral tube 6 pushes the water sample into the filter holes 7 for filtration, so that the filter plate 8 installed in the filter holes 7 filters the sediment and waterweeds. The filtered water sample flows into the water storage cavity 5 for storage. When the water sample is pulled out of the water surface, the counterweight 15 is manually pushed to slide into the cylinder body 1, so that the counterweight 15 is separated from the top end of the drain pipe 14, thereby enabling the drain pipe 14 to communicate with the water storage cavity 5, and the drain pipe 14 can discharge the filtered water sample in the water storage cavity 5 for collection. And by the counterweight 15 abutting against the drain pipe 14, the drain pipe 14 is always kept in a closed state underwater, thereby avoiding the water flow with sediment from entering the water storage cavity 5 along the drain pipe 14.

[0028] In the above embodiments, when the cylinder 1 is placed in water, the cylinder 1 is pulled into the water by the configuration block installed at the bottom of the cylinder 1, so that the water sample with sediment and waterweeds flows into the collection tank 2 for collection. The collection tank 2 is interconnected with the threaded pipe, so that the water sample collected in the collection tank 2 flows into the threaded pipe. When the water sample enters the threaded pipe, the threaded pipe is driven to rotate at a high speed, so that the water sample flows into the water storage cavity 5 along the filter holes 7 opened on the side wall of the threaded pipe under the action of centrifugal force. The waterweeds mixed in the water sample are filtered through the filter holes 7, so that the waterweeds are separated from the water sample. And the sediment mixed in the water sample is filtered by the filter plate 8 installed in the filter holes 7, so that the sediment in the water sample is separated and flows into the water storage cavity 5 for storage. When the cylinder 1 is pulled onto the shore, by pushing the counterweight 15 upward, the configuration block is disengaged from the port of the drain pipe 14, so that the water sample stored in the water storage cavity 5 flows out along the drain pipe 14. It can not only automatically filter the water sample during the collection process, but also improve the collection efficiency of the inspectors, and avoid wasting time by filtering the water sample separately.

[0029] As a further embodiment provided by the present utility model, a plug block 10 is fixedly installed in the cylinder 1. A collection groove 11 is opened in the plug block 10. A spiral pipe 6 is movably connected in the collection groove 11. Symmetrically arranged waste material grooves 17 are opened at the bottom end of the spiral pipe 6. The waste material grooves 17 are communicated with the collection groove 11.

[0030] Specifically, after the water sample is filtered, the sediment and waterweeds filtered out by the filter plate 8 continuously slide down along the spiral pipe 6 and flow into the collection groove 11 through the waste material grooves 17 for collection, so as to avoid the sediment and waterweeds accumulating in the spiral pipe 6 and affecting the filtering effect of the filter plate 8.

[0031] As still another embodiment provided by the present utility model, a sealing block 18 is fixedly installed on the side wall of the cylinder 1. The side wall of the sealing block 18 abuts against the inside of the collection groove 11.

[0032] Specifically, the collection groove 11 is sealed by the sealing block 18, so that the collection groove 11 is in a sealed state when the cylinder 1 is in water, avoiding water flow flowing into the spiral pipe 6 along the collection groove 11. And when the water sample collection is completed, the sealing block 18 can be pulled out to clean the sediment and waterweeds collected in the collection groove 11.

[0033] As yet another embodiment provided by the present utility model, a motor 16 is fixedly installed at the bottom end of the plug block 10. The output end of the motor 16 is fixedly connected to the spiral pipe 6. A circumferentially arrayed plurality of balls 9 are arranged on the side wall of the spiral pipe 6.

[0034] Specifically, the motor 16 installed in the plug 10 provides power to the spiral tube 6, enabling the spiral tube 6 to rotate at high speed underwater. And the installed ball bearings 9 reduce the friction generated between the spiral tube 6 and the inner wall of the cylinder body 1, making the rotation of the spiral tube 6 more stable.

[0035] As another embodiment further provided by the present utility model, through holes 12 symmetrically arranged are formed at the top end of the plug 10, and the through holes 12 communicate with the water storage cavity 5.

[0036] Furthermore, a drainage chamber 13 is formed in the cylinder body 1. The drainage chamber 13 communicates with the through holes 12, and a drain pipe 14 is movably connected in the drainage chamber 13.

[0037] Specifically, the drainage chamber 13 is communicated with the water storage cavity 5 through the through holes 12 formed in the plug 10, so that the water sample stored in the water storage cavity 5 can pass through the through holes 12 and flow into the drainage chamber 13 for collection. Thus, when the drain pipe 14 is opened, the water sample can flow out along the drain pipe 14.

[0038] Working principle: When the cylinder body 1 is put into water, the cylinder body 1 is pulled into the water by the configuration block, so that the water sample flows into the water collecting tank 2 for collection. Since the spiral tube 6 communicates with the water collecting tank 2, the water sample flows along the water collecting tank 2 into the spiral tube 6. When the water sample flows into the threaded tube, the motor 16 installed in the plug 10 drives the spiral tube 6 to rotate, so that the spiral tube 6 generates centrifugal force. Thus, under the action of the centrifugal force, the water sample flows into the water storage cavity 5 along the filter holes 7 formed on the side wall of the threaded tube. The filter plate 8 installed in the filter holes 7 filters out sediment and waterweeds, so that the water sample can flow into the water storage cavity 5 for collection only after being filtered. And the filtered sediment flows into the collection tank 11 along the waste material groove 17 formed in the spiral tube 6 for collection, preventing the sediment from accumulating in the filter holes 7 and affecting the efficiency of the water sample entering the water storage cavity 5. The drainage chamber 13 is communicated with the water storage cavity 5 through the through holes 12 formed in the plug 10, so that the water sample in the water storage cavity 5 can flow into the drainage chamber 13 for collection. When the cylinder body 1 is pulled onto the shore, the worker counterweight block 15 moves upward, so that the configuration block disengages from the port of the drain pipe 14, thus opening the drain pipe 14 and discharging the water sample in the drainage chamber 13. The staff can then collect the water sample. After the water sample collection is completed, by opening the sealing block 18, the sediment and waterweeds can be cleaned up.

[0039] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
