Description
Technical Field
[0001] This application relates to the technical field of water quality testing and sampling, and in particular to a water quality sampling device for exploration. Background Technology
[0002] Water sampling devices are used to sample and test water from different bodies of water or at different depths within the same body of water. They play an important role in environmental protection and water quality monitoring.
[0003] Existing water sampling devices involve operators using ropes to attach a retrieval bucket and lowering it into the water for direct sampling. While this method is simple and convenient, it is difficult to accurately control the sampling depth during the sampling process. This makes it impossible to precisely sample water at different depths in the water, resulting in water samples that may not accurately reflect the water quality at the target depth or fully represent the overall water quality of the target body, thus affecting the accuracy of subsequent analysis results.
[0004] The aforementioned technologies suffer from the problem of difficulty in accurately controlling sampling depth, leading to inaccurate sampling at different depths. Utility Model Content
[0005] In order to accurately control the sampling depth and improve the accuracy of sampling, this application provides a water quality sampling device.
[0006] This application provides a water quality sampling device, which adopts the following technical solution:
[0007] A water quality sampling device, comprising:
[0008] Sample tube;
[0009] Two hinged caps are hinged to one end of the sample cylinder;
[0010] A sealing cap, the sealing cap being threadedly connected to the end of the sample cylinder away from the opening / closing cap;
[0011] A water inlet control component is installed on the sample cylinder and is used to control the sample cylinder to collect water samples at different depths.
[0012] The counterweight is connected to the sample cylinder via a mounting bracket;
[0013] Two sets of mounting components are installed on the sample cylinder, and the mounting components are used to install counterweights.
[0014] By adopting the above technical solution, the sealing cap is tightened on the sample cylinder. According to the predetermined sampling depth, a counterweight of corresponding weight is installed in the installation component. The water quality sampling device is placed in the water area to be sampled. Under the action of the water pressure, the water inlet control component precisely controls the opening and closing of the cap at the predetermined depth, allowing water to enter the sample cylinder. Under the action of the atmospheric pressure in the sample cylinder, the water inlet control component controls the closing of the cap to complete the sampling, thus achieving accurate sampling at the predetermined depth. After sampling, the device is retrieved, the counterweight is removed, the sealing cap is unscrewed, and the sample is poured out for testing. The sampling depth is controllable, greatly improving the accuracy of sampling.
[0015] Optionally, the water inlet control component includes:
[0016] The first corrugated tube is fixedly connected at both ends to the two opening and closing caps on the side near the inner cavity of the sample cylinder.
[0017] A first air guide tube, one end of which is connected to the top wall of the sample tube, and the other end of which is away from the sample tube is connected to the first corrugated tube.
[0018] The second corrugated tube is fixedly connected at both ends to the side of the two opening and closing caps away from the inner cavity of the sample cylinder.
[0019] An airbag is fixedly installed on the sample cylinder, and an inflation port is provided on the airbag;
[0020] The second air duct has one end connected to the second corrugated tube and the other end of the second air duct away from the second corrugated tube connected to the airbag.
[0021] An electric valve is installed on the second air duct and is electrically connected to an external control console.
[0022] By adopting the above technical solution, and through the coordinated operation of the first corrugated pipe, the first air guide pipe, the second corrugated pipe, the airbag, the second air guide pipe, and the electric valve, the water inlet control component can accurately control the sampling depth.
[0023] When sampling is required, the device is placed in the water area to be sampled. When the device reaches the sampling depth, the electric valve is opened by controlling the external control console. Under the action of water pressure, the gas in the airbag enters the second bellows, thereby controlling the expansion of the second bellows. Since the second bellows is connected to the opening and closing cover, its expansion will drive the opening and closing cover to open, thereby controlling the water sample to enter the sample tube.
[0024] Water enters the sample cylinder, and the air inside the sample cylinder, under the action of water, enters the first corrugated tube through the first air guide tube, thereby controlling the expansion of the first corrugated tube. Since the first corrugated tube is connected to the opening and closing cap, its expansion will drive the opening and closing cap to close, and the sampling is completed. The water inlet control component makes the sampling process more precise and controllable, greatly improving the accuracy of sampling.
[0025] Optionally, both sets of the installation components include:
[0026] The mounting box is fixedly mounted on the sample cylinder;
[0027] A snap-fit block is hinged inside the mounting box, and the mounting bracket is engaged with the snap-fit block.
[0028] A first spring, one end of which is fixed to the mounting box, and the end of which is away from the mounting box abuts against the buckle block;
[0029] The second spring has one end fixed to the mounting box and the end of the second spring away from the mounting box abutting against the buckle block. The first spring is parallel to the axis of the second spring.
[0030] A button, which is fixedly connected to the latch block.
[0031] By adopting the above technical solution, and through the design of the mounting box, buckle block, first spring, second spring, button, and mounting bracket, the counterweight can be easily installed and disassembled. The operator only needs to press the button to disengage the buckle block from the mounting bracket, and can quickly replace or adjust the counterweight. This allows the device to flexibly adjust the counterweight according to the needs of different water areas and depths, so as to ensure the stability of the device and the sampling accuracy.
[0032] Optionally, a filter screen is fixedly installed inside the sample tube.
[0033] By adopting the above technical solution, the filter screen can effectively intercept large particulate impurities and suspended solids in the water sample, making the water sample entering the sample tube clearer, reducing interference factors in subsequent analysis, and improving the accuracy and reliability of water quality testing.
[0034] Optionally, the sample tube is coated with graduation lines.
[0035] By adopting the above technical solution, the sample tube is made of transparent material. The scale lines on the wall of the sample tube allow the water quality sampling device to intuitively display the sampling amount, which facilitates sampling operation, improves experimental efficiency, facilitates recording and reporting, and enhances the ease of use of the device and the accuracy of experimental data.
[0036] Optionally, a hanging ring is fixedly installed at the top of the sample tube.
[0037] By adopting the above technical solution, operators can easily remove or place the sample tube from the sampling water area using the hanging ring, simplifying the sampling process and improving the convenience and efficiency of the operation.
[0038] Optionally, a sealing ring is fixedly installed at the closure of the sample tube and the opening / closing cover.
[0039] By adopting the above technical solution, the sealing ring, as a key component connecting the sample tube and the opening and closing cap, ensures that the two form a good sealing effect when closed, preventing leakage of water samples during sampling, transportation or storage, ensuring the integrity and purity of the water samples, and thus ensuring the accuracy and reliability of subsequent water quality analysis.
[0040] Optionally, a rotating door is hinged to the mounting bracket.
[0041] By adopting the above technical solution, operators can easily open and close the internal space of the mounting bracket, thereby facilitating the replacement of counterweights of different weights.
[0042] In summary, this application includes at least one of the following beneficial technical effects:
[0043] 1. Through the coordinated operation of the first corrugated pipe, the first air guide pipe, the second corrugated pipe, the air bag, the second air guide pipe and the electric valve, the water inlet control component can accurately control the opening or closing of the cover, making the sampling process more accurate and controllable.
[0044] 2. The design of the mounting box, buckle block, first spring, second spring, button and mounting bracket allows for easy installation and removal of the counterweight. Operators can quickly replace or adjust the counterweight by simply pressing the button to disengage the buckle block from the mounting bracket. This allows the device to flexibly adjust the counterweight according to the needs of different water areas and depths, ensuring the stability of the device and the sampling accuracy.
[0045] 3. By installing counterweights of appropriate weight into the mounting components, the sampling depth of the water quality sampling device can be controlled, thereby improving the accuracy of sampling. Attached Figure Description

[0054] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0055] This application discloses a water quality sampling device.
[0056] Reference Figure 1 and Figure 2The water quality sampling device includes a sample cylinder 1, two hinged covers 2, a sealing cover 3, a water inlet control assembly 5, an installation assembly 6, a mounting frame 4, and a counterweight 7. The sample cylinder 1 is vertically arranged, with the two hinged covers 2 hinged to the bottom of the sample cylinder 1, and the sealing cover 3 threaded to the top of the sample cylinder 1. The water inlet control assembly 5 is installed on the sample cylinder 1 and is used to control the collection of water samples at different depths. The counterweight 7 is connected to the sample cylinder 1 through the mounting frame 4, and the installation assembly 6 is installed on the sample cylinder 1 and is used to install the counterweight 7.
[0057] In use, the sealing cap 3 is tightened onto the sample cylinder 1. According to the predetermined sampling depth, a counterweight 7 of corresponding weight is placed into the mounting frame 4. The mounting frame 4 is then installed onto the sample cylinder 1 by the mounting component 6. The water quality sampling device is placed into the water area to be sampled. Under the action of water pressure, the water inlet control component 5 precisely controls the opening and closing of the cover 2 at the predetermined depth for sampling. After sampling is completed, the device is retrieved, the sealing cap 3 is unscrewed, and the water sample is poured out from the top of the sample cylinder 1 for testing.
[0058] Reference Figure 1 and Figure 2 The sample tube 1 is a cylindrical tube made of transparent material. The tube wall of the sample tube 1 is coated with scale lines 9. A hanging ring 10 is fixedly installed at the top of the sample tube 1. The two opening and closing covers 2 are semi-circular and are hinged together. They are installed at the bottom of the sample tube 1, and the outer circumference of the opening and closing covers 2 abuts against the inner wall of the bottom of the sample tube 1.
[0059] A sealing ring 11 is fixedly installed at the bottom of the inner wall of the sample cylinder 1. When the opening and closing cover 2 is closed with the sample cylinder 1, the opening and closing cover 2 abuts against the sealing ring 11. The sealing cover 3 is threadedly connected to the top of the sample cylinder 1. A filter screen 8 is fixedly installed inside the sample cylinder 1.
[0060] Reference Figure 2 and Figure 3 The water inlet control assembly 5 includes a first corrugated pipe 51, a first air guide pipe 52, a second corrugated pipe 53, an air bladder 54, a second air guide pipe 55, and an electric valve 56. The two ends of the first corrugated pipe 51 are respectively fixedly connected to the side of the two opening and closing caps 2 near the inner cavity of the sample cylinder 1.
[0061] One end of the first air guide tube 52 is connected to the top wall of the sample cylinder 1, and the other end of the first air guide tube 52 away from the sample cylinder 1 is connected to the first corrugated tube 51. The two ends of the second corrugated tube 53 are respectively fixedly connected to the side of the two opening and closing caps 2 away from the inner cavity of the sample cylinder 1.
[0062] An air bladder 54 is fixedly installed on the bottom end of the sample cylinder 1, and an inflation port is provided on the air bladder 54. One end of the second air guide tube 55 is connected to the second corrugated tube 53, and the other end of the second air guide tube 55 away from the second corrugated tube 53 is connected to the air bladder 54. An electric valve 56 is provided on the second air guide tube 55.
[0063] In use, an appropriate amount of gas is injected into the air bladder 54 through the inflation port according to the sampling depth. The water quality sampling device is placed in the water area to be sampled. After the device descends to the designated depth, the electric valve 56 is opened by the external control console. The gas in the air bladder 54 enters the second corrugated pipe 53, thereby controlling the expansion of the second corrugated pipe 53. The second corrugated pipe 53 controls the opening and closing cover 2 to open, and water enters the sample cylinder 1. When the water level in the sample cylinder 1 reaches the designated height, the original air in the sample cylinder 1 enters the first corrugated pipe 51 through the first air guide pipe 52. The expansion of the first corrugated pipe 51 controls the closing of the opening and closing cover 2. When the opening and closing cover 2 is closed, the water level in the sample cylinder 1 is always lower than the position of the first air guide pipe 52, so that the water quality sampling device can accurately sample water quality at different depths.
[0064] Reference Figure 2 and Figure 3 The installation components 6 are provided in two sets. The two sets of installation components 6 are symmetrically installed on the bottom outer wall of the sample cylinder 1. Both sets of installation components 6 include an installation box 61, a buckle block 62, a first spring 63, a second spring 64, and a button 65.
[0065] The mounting box 61 is rectangular and vertically positioned. It is fixedly mounted on the sample cylinder 1. The mounting box 61 has a mating hole for inserting the mounting bracket 4. The snap-fit block 62 is hinged to the mounting box 61. One end of the first spring 63 is fixed to the mounting box 61, and the end of the first spring 63 away from the mounting box 61 abuts against the snap-fit block 62.
[0066] One end of the second spring 64 is fixed to the mounting box 61, and the end of the second spring 64 away from the mounting box 61 abuts against the buckle block 62. The first spring 63 is parallel to the axis of the second spring 64. The button 65 is fixedly connected to the buckle block 62. The mounting bracket 4 is engaged with the buckle block 62. The counterweight 7 is placed inside the mounting bracket 4. The mounting bracket 4 is hinged with a rotating door 41.
[0067] When in use, depending on the predetermined sampling depth, a counterweight 7 of different weight should be installed at the bottom of the sample tube 1. The counterweight 7 is placed into the mounting frame 4 through the rotating door 41. The rotating door 41 is closed, and the mounting frame 4 is extended into the mounting box 61. The latching block 62 latches the mounting frame 4 to achieve the counterweight of the device.
[0068] When it is necessary to remove the mounting component 6, press both buttons 65 at the same time. The second spring 64 retracts, the mounting bracket 4 disengages from the snap-fit block 62, and the mounting component 6 separates from the sample cylinder 1, so as to realize the flexible replacement of the counterweight block 7 to collect water samples at different depths.
[0069] The implementation principle of the water quality sampling device in this application embodiment is as follows: When using the water quality sampling device for sampling, the sampling cylinder is equipped with counterweights 7 of different weights through the flexibly detachable installation component 6, thereby enabling the water quality sampling device to collect water at different depths. The sealing cap 3 is tightened on the sample cylinder 1, and the water quality sampling device is placed in the water area to be sampled. The opening and closing time of the opening and closing cap 2 is precisely controlled by the water inlet control component 5 under pressure, thereby accurately controlling the sampling depth. After sampling is completed, the device is retrieved, the sealing cap 3 is unscrewed, and the water sample is poured out from the top of the sample cylinder 1 for testing, thereby improving the accuracy of sampling.
[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
