Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, and specifically relates to a water quality testing sampler. Background Technology

[0002] Water resources are an indispensable resource for human society. Water is used in human life and production activities. Depending on the purpose, some industrial production consumes a lot of water, while others consume little or no water. In addition, the requirements for water quality are different for different purposes. When testing the water quality in different places, it is necessary to use a sampler to collect samples.

[0003] Water quality varies at different depths. Existing samplers can sample water at different depths, but after each sampling, the sampler usually needs to be pulled up to retrieve the water. When sampling is needed again, the sampler needs to be put back into the sampling site. It cannot sample water at different depths at the same time, so its functionality is poor and the sampling efficiency is low. Utility Model Content

Detailed Implementation

[0033] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] like Figure 1-7 As shown, this utility model provides a water quality testing sampler, comprising:

[0035] Base 1, with a mounting groove 11 on the top of base 1, and an assembly plate 12 fixedly installed inside the upper side of the mounting groove 11;

[0036] Motor 13 is fixedly installed on the inner wall of the bottom side of the mounting groove 11. The output shaft of motor 13 passes through the mounting plate 12 and is fixedly installed with a connecting block 14. A cross-shaped groove 15 is opened on the top of the connecting block 14. Motor 13 is a motor with a holding brake function.

[0037] Cross-shaped block 2, placed inside cross-shaped groove 15;

[0038] The collection block 3 is fixedly installed on the top of the cross-shaped block 2, and the top of the collection block 3 is provided with several placement slots 31 around it.

[0039] Sampling bottles 4 are provided in several units, and the sampling bottles 4 are placed in several placement slots 31 respectively. The top of the sampling bottle 4 is provided with a first sealing ring 41.

[0040] The sealing cover 43 is detachably installed on the top of the base 1. The tops of several first sealing rings 41 abut against the upper inside of the sealing cover 43. The bottom of the sealing cover 43 is provided with a second sealing ring 44.

[0041] The water inlet mechanism 5 is eccentrically positioned on the top of the sealing cap 43 and aligned with the position of one of the sampling bottles 4. Specifically, the water inlet mechanism 5 includes a pipe 51, which is eccentrically positioned on the top of the sealing cap 43 and aligned with the position of one of the sampling bottles 4. The pipe 51 is equipped with a solenoid valve, and a filter element 52 is detachably mounted on the top of the pipe 51. A second battery and a signal transmitter are sequentially mounted on the inner periphery of the sealing cap 43. The solenoid valve, the second battery, and the signal transmitter are all electrically connected to the WeChat controller 6.

[0042] After the sealing cap 43 is connected to the base 1, the position of the sealing cap 43 is fixed, and the pipe 51 is aligned with the center of the sampling bottle 4. The solenoid valve is in the closed state. When the base 1 connected to the sealing cap 43 is placed in the water and reaches the specified water depth, the staff can send a control signal to the microcontroller through the external control terminal. The microcontroller 6 controls the solenoid valve to open, and then the pipe 51 starts to flow water normally, draining water into the sampling bottle 4 for water sampling. After a period of time, the solenoid valve can be closed, and the motor 13 can be controlled to rotate. The motor 13 drives the sampling block 3 to rotate evenly, so that the adjacent sampling bottle 4 is re-aligned with the sealing cap 43. Repeat the above operation process to carry out the next sampling. In this way, the sampling operation of water at different depths can be completed in one go.

[0043] Inside the mounting slot 11, a microcontroller 6, an underwater wireless signal transmitter 7, and a first battery 8 are installed in sequence. The water entry mechanism 5, the motor 13, and the first battery 8 are all electrically connected to the microcontroller 6. The microcontroller 6 is electrically connected to an external control terminal through the underwater wireless signal transmitter 7.

[0044] The lifting mechanism 9 is located behind the base 1 and is fixedly connected to the periphery of the base 1 via a connecting component 911. Specifically, the lifting mechanism 9 includes a base plate 91, which is located behind the base 1. Four moving wheels 92 are evenly distributed on the bottom of the base plate 91. A support column 93 is fixedly installed on the top of the base plate 91. A support column 94 is fixedly installed on the upper end of the support column 93. An assembly groove 96 is opened at the bottom of the support column 94. A winding wheel 97 is rotatably mounted on the front side inside the assembly groove 96. A drive motor 98 is fixedly installed on one side of the support column 94. The output shaft of the drive motor 98 is connected to the winding wheel 97. A pull rope 99 is fixedly installed around the periphery of the winding wheel 97. One end of the pull rope 99 is fixedly connected to the connecting component 911.

[0045] When in use, the base plate 91 is moved to the designated position so that the base 1 is suspended above the water surface. The output shaft of the drive motor 98 can be controlled to rotate through the external control terminal. The output shaft of the drive motor 98 can drive the winding wheel 97 to complete the winding and unwinding operation of the pull rope 99. When unwinding, the base 1 descends and can be slowly put into the water. Based on the unwinding length of the pull rope 99, the depth of the base 1 below the water surface can be determined, which is convenient for sampling. After the sampling is completed, the pull rope 99 is wound up again to pull the base 1 out of the water.

[0046] The pull rope 99 has a length mark around its circumference; the length mark makes it easy to directly determine the unwinding length of the pull rope 99.

[0047] The connecting component 911 includes an annular counterweight 912, which is fixedly installed around the base 1. A U-shaped mounting rod 913 is fixedly installed on the upper side of the annular counterweight 912, and one end of the pull rope 99 is fixedly connected to the center of the top of the U-shaped mounting rod 913. The annular counterweight 912 can increase the overall weight of the base 1, making it easier for the base 1 to be directly immersed in water.

[0048] A reinforcing rib 95 is provided between the support column 94 and the support column 93; the setting of the reinforcing rib 95 can increase the connection strength between the support column 94 and the support column 93.

[0049] A sealing ring 42 is fixedly installed on the top of the base 1. The sealing ring 42 has a first threaded section around its periphery. The sealing cover 43 has a second threaded section on its lower inner side that is threaded to the first threaded section. When installing the sealing cover 43, rotate the sealing cover 43 to connect it to the sealing ring 42 until the second sealing ring 44 is pressed against the top of the base 1 to complete the seal and prevent water from entering. After being pressed, the pipe 51 will be aligned with the center of the top of one of the sampling bottles 4. The operation is simple and convenient.

[0050] The sealing cap 43 has a handle on top; holding the handle makes it easy to rotate the sealing cap 43 to tighten it.

[0051] The device is used as follows:

[0052] In the initial state, the sampling block 3 needs to be installed. After placing several sampling bottles 4 in several placement slots 31, the cross-shaped block 2 is aligned with the cross-shaped slot 31 and placed in. The motor 13 is a brake motor. When it is not started, its output shaft does not rotate. After each sampling, the motor 13 needs to be controlled by the external control terminal to drive the cross-shaped block 2 to perform a reset operation. This ensures that the cross-shaped block 2 is in the initial state before each sampling. After the cross-shaped block 2 is placed in, it is connected to the sealing ring 42 through the sealing cover 43 until the second sealing ring 44 is pressed against the top of the base 1 to complete the seal. At the same time, the first sealing ring 41 set on the top of several sampling bottles 4 will press against the upper inside of the sealing cover 43 to complete the seal.

[0053] When sampling water, the base plate 91 is moved to the designated location, and the drive motor 98 is started to unwind the water. The base 1 is then placed in the water, and the sampling depth is determined by the length of the unwinding rope 99. During sampling, the solenoid valve is activated by the external control terminal, and water begins to enter the pipe 51 and drain into the corresponding sampling bottle 4. The solenoid valve is then closed after a period of time. The sampling bottle 4 has a large volume. After one sampling is completed, the base 1 is lowered to different water depth areas, and the sampling block 3 is driven to rotate by the tapping motor 13. The motor 13 can drive the sampling block 3 to rotate at a fixed angle each time, thereby aligning an adjacent sampling bottle 4 with the pipe 51 for sampling again. Repeating the above operation allows for multiple samplings to be completed by lowering the base 1 once, resulting in higher sampling efficiency. After sampling is completed, the output shaft of the motor 13 can be reset with one key control via the external control terminal. Finally, the base 1 is pulled up, the sealing cover 43 is removed, and the sampling block 3 is taken out. All electronic devices used in this application are waterproof, resulting in a longer service life.

[0054] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
