Description

Technical Field

[0001] This utility model belongs to the field of water quality sampling and analysis technology, specifically relating to a water quality sampling and analysis device with a calibration spectrum function. Background Technology

[0002] Water quality analysis, also known as water chemical analysis, involves using chemical and physical methods to determine the content of various chemical components in water. A search reveals that application number "CN202323044008.1" discloses "a water quality analysis sampling device," which describes a method that "facilitates sampling by utilizing a pump, connecting pipe, and nozzle, and conveniently discharges water into a sampling bottle for analysis by the water quality analyzer itself, resulting in low cost." While the pump, connecting pipe, and nozzle facilitate sampling and discharge water into a sampling bottle, and the water is indeed analyzed by the water quality analyzer itself, this method is indeed low-cost and therefore has a stronger photocatalytic effect. However, the above-mentioned document still has the following problems in practical use: In practical use, it is inconvenient to adjust the sampling, cannot sample water in deeper areas, cannot calibrate the spectrum, and is prone to clogging the pipes with debris in the water during sampling, which is inconvenient to clean.

[0003] Therefore, providing a device that can adjust sampling, perform spectral calibration, block debris, and facilitate cleaning is highly practical. Utility Model Content

The user then places the hose, along with the suction head and its external components, into the water to be sampled. The user then activates the water pump via the controller, generating suction that draws the water into the suction head. The water is then fed through the hose into the delivery pipe and subsequently into the take-up drum.

When cleaning the filter cartridge after prolonged use, the user moves the limiting ring upwards via the drive assembly, causing the limiting head to slide out of the insertion rod and release its restriction. The user can then pull the auxiliary ring to one side to slide the insertion rod out of the plug. The protective filter cartridge can then be removed and cleaned by pulling it downwards through the plug, achieving both protection and quick disassembly. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example Please see Figure 1-5 A water quality sampling and analysis device with spectral calibration function includes a protective box 100, an adjustment sampling and spectral calibration component 200, and a protective and quick-disassembly box 300.

[0019] Please refer to the details. Figure 1 A spectrometer 110 is installed on the top of the inner wall of the protective box 100.

[0020] Please see Figure 1-3The adjustment sampling and spectral calibration component 200 includes two fixed brackets 210 disposed on one side of the protective box 100. A torque motor 220 is disposed between the two fixed brackets 210. A winding drum 230 is disposed on one side of the output shaft of the torque motor 220, which penetrates the inner wall of the protective box 100. A connecting rod 240 is sealed and connected to one side of the winding drum 230. A rotating joint 250 is sealed and connected to one side of the connecting rod 240, which penetrates the protective box 100. A conveying pipe 260 is sealed and connected to the top of the winding drum 230. A flexible hose 270 is sealed and connected to one end of the conveying pipe 260. A suction head 280 is sealed and connected to the bottom of the flexible hose 270.

[0021] In one specific embodiment, the included torque motor 220 allows the user to easily sample deeper water. The user activates the torque motor 220 via a controller, causing the take-up drum 230 to rotate. The rotating drum 230 lowers and discharges the hose 270. The user then places the hose 270, connected to the suction head 280 and its external components, into the water to be sampled. The user then activates the water pump 800 via the controller, generating suction that draws water into the suction head 280, which then passes it through the hose 270 into the delivery pipe 260 and finally into the take-up drum 230. After water enters the take-up drum 230, it is sent to the liquid delivery pipe 700 through the rotary joint 250 and then to the water pump 800. The water pump 800 sends the water into the detection pool 1000 through the connecting pipe 900 for testing. During testing, when the user turns on the spectrometer 110 via the controller, the mercury lamp 1200 can be turned on simultaneously to scan characteristic spectral lines such as 253.65nm / 546.07nm. The data from the spectrometer 110 is compared. If the difference is >0.1nm, the grating angle is automatically adjusted to achieve automatic calibration, thereby adjusting the sampling and achieving the purpose of detecting and automatically calibrating water in deeper areas.

[0022] Please see Figure 4-5 The protective and quick-release assembly 300 includes a retaining ring 310 disposed on the outer wall of the suction head 280. Two plugs 320 are inserted and connected inside the retaining ring 310. A protective filter cartridge 330 is disposed at the bottom of the two plugs 320. Insert rods 340 are inserted and connected inside the two plugs 320. An auxiliary ring 350 is disposed on one side of each of the two insert rods 340. A limiting head 360 is inserted and connected to the top of each of the two insert rods 340. A limiting ring 370 is disposed at the top of each of the two limiting heads 360.

[0023] In one specific embodiment, the protective filter cartridge 330 allows for the filtration of larger debris and algae in the water during suction testing by the suction head 280, without affecting the testing structure. When the protective filter cartridge 330 needs cleaning after prolonged use, the user moves the limiting ring 370 upwards via the drive assembly 500, causing the limiting head 360 to move upwards and slide out of the insertion rod 340, releasing the limitation on the insertion rod 340. At this point, the user pulls the auxiliary ring 350 to one side, causing the insertion rod 340 to slide out of the plug 320. The user can then pull the protective filter cartridge 330 downwards via the plug 320 to remove it for cleaning, thus achieving both protection and quick disassembly and cleaning.

[0024] Please see Figure 3 The auxiliary winding and unwinding assembly 400 includes a limiting rod 410 disposed on the inner wall of the protective box 100. A movable plate 420 is slidably connected to the outer wall of the limiting rod 410. A lead screw nut 430 is threadedly connected to the bottom of the movable plate 420. One side of the lead screw nut 430 is rotatably connected to one side of the inner wall of the protective box 100. A connector is provided through the protective box 100 on the other side of the lead screw nut 430. Synchronous pulleys 440 are provided on the outer walls of both the connector and the output shaft of the torque motor 220. A belt 450 is drivenly connected to the outer walls of the two synchronous pulleys 440. One end of the movable plate 420 is slidably connected to the hose 270. An auxiliary groove is provided at the bottom of the protective box 100.

[0025] In one specific embodiment, the provided synchronous pulley 440 facilitates the rotation of the output shaft of the torque motor 220 during use, thereby driving one of the synchronous pulleys 440 to rotate. The rotation of one synchronous pulley 440 drives the other synchronous pulley 440 to rotate via the belt 450. The rotation of the other synchronous pulley 440 drives the connector to rotate, which in turn drives the lead screw nut 430 to rotate. The rotation of the lead screw nut 430 causes the moving plate 420 to move through the engagement of the external thread with the limiting rod 410. The movement of the moving plate 420 causes the internal hose 270 to move and deflect, so that the moving plate 420 can move when the winding drum 230 winds up and unwinds the hose 270. This allows the hose 270 to be wound evenly on the winding drum 230 and also facilitates the unwinding of the hose 270, thereby achieving the purpose of assisting in winding.

[0026] Please see Figure 4The drive assembly 500 includes a fixing head 510 disposed at the bottom of the limiting ring 370. The bottom of the fixing head 510 is hinged to a first hinge seat 520. The bottom of the first hinge seat 520 is fixedly connected to the fixing ring 310. The top of the limiting ring 370 is provided with two second hinge seats 530. The top of the two second hinge seats 530 is hinged to a connecting frame 540. The connecting frame 540 is internally slidably connected with two support rods 550. The top of the two support rods 550 is provided with a support head. The bottom of the two support heads is provided with a spring 560. The bottom of the two springs 560 is fixedly connected to the connecting frame 540. The bottom of the two support rods 550 is fixedly connected to a suction head 280.

[0027] In one specific embodiment, the connecting frame 540 allows the user to pull the pull head upwards, thereby moving the connecting frame 540 upwards. The upward movement of the connecting frame 540 causes the spring 560 to contract and store energy. The upward movement of the connecting frame 540 also causes the second hinge seat 530 to move upwards. The upward movement of the second hinge seat 530 causes the limiting ring 370 to shift upwards. The limiting ring 370 shifts upwards through the cooperation of the first hinge seat 520 and the fixed head 510, thereby achieving the purpose of driving.

[0028] Please see Figure 5 The interior of the protective filter cartridge 330 is movably connected to the outer wall of the suction head 280, and the interior of the hose 270 is wound and connected to the winding drum 230.

[0029] In one specific embodiment, the provided take-up drum 230 allows the hose 270 to be evenly wound up when sampling is not required, enabling more stable winding during use and improving work efficiency.

[0030] Please see Figure 1 The top and bottom of the rotary joint 250 are equipped with a reinforcing frame 600. The end of the rotary joint 250 is sealed and connected to a liquid delivery pipe 700. The end of the liquid delivery pipe 700 is sealed and connected to a water pump 800. One end of the water pump 800 is sealed and connected to a connecting pipe 900.

[0031] In one specific embodiment, the provided reinforcing frame 600 facilitates the support and fixation of the rotary joint 250 during use, making the rotary joint 250 more stable during use and preventing it from shaking.

[0032] Please see Figure 2An isolation plate is provided in the middle of the inner wall of the protective box 100. A detection pool 1000 is provided at the bottom of one end of the inner wall of the protective box 100. A protective door 1100 is hinged to one end of the protective box 100. A door lock and a handle are provided at one end of the protective door 1100. Two mercury lamps 1200 are provided on one side of one end of the protective box 100.

[0033] In one specific embodiment, the protective door 1100 allows users to unlock the door lock with a key and open the protective door 1100 with a handle so that the detection pool 1000 inside the protective box 100 can be cleaned during use.

[0034] Please see Figure 2 The two reinforcing frames 600 and the water pump 800 are fixedly connected to the protective box 100 on one side. The end of the connecting pipe 900 passes through the inner wall of the protective box 100 and corresponds to the detection pool 1000. Support frames are provided on both sides of the protective box 100, and a controller is provided at the top corner of the protective box 100.

[0035] In one specific embodiment, the provided support frame facilitates the support and fixation of the protective box 100 during use, making the protective box 100 more stable during use and preventing shaking.

[0036] Please see Figure 1-5 The spectrometer 110, torque motor 220, water pump 800 and mercury lamp 1200 are all electrically connected to the controller, and the controller is electrically connected to an external power supply.

[0037] In one specific embodiment, a controller is provided to facilitate power supply control of electrical equipment, enabling the equipment to be powered on when needed, thus avoiding situations where power cannot be supplied when power is required.

[0038] In use, the torque motor 220 is provided for easy sampling in deeper water. The user activates the torque motor 220 via the controller, causing the take-up drum 230 to rotate. The rotating drum 230 lowers and discharges the hose 270. The user then places the hose 270, connected to the suction head 280 and its external parts, into the water to be sampled. The user then activates the water pump 800 via the controller, generating suction that causes the suction head 280 to... The system generates suction to draw water in and delivers it through hose 270 to delivery pipe 260, then into take-up drum 230. Once inside drum 230, the water is delivered through rotary joint 250 to liquid delivery pipe 700 and then to water pump 800. Water pump 800 then delivers the water through connecting pipe 900 into detection pool 1000 for testing. During testing, for user convenience, the mercury lamp 1200 can be simultaneously turned on when the spectrometer 110 is activated via controller, scanning 253.65nm / 546.07nm. The characteristic spectral lines are compared with the data from the spectrometer 110. If the variation is >0.1nm, the grating angle is automatically adjusted to achieve automatic calibration, thereby adjusting the sampling and achieving the purpose of detecting and automatically calibrating water in deeper areas. Then, the protective filter cartridge 330 is provided to facilitate suction detection by the suction head 280. The protective filter cartridge 330 can filter larger debris and algae in the water without affecting the detection structure, providing protection. However, for prolonged use, the protective filter cartridge 330 needs to be disinfected. When cleaning the inside of the protective filter cartridge 330, the user drives the limit ring 370 upward through the drive component 500, causing the limit ring 370 to drive the limit head 360 upward, and then slide out from the insertion rod 340. Finally, the limit on the insertion rod 340 is released. At this time, the user pulls the auxiliary ring 350 to one side, causing the insertion rod 340 to slide out from the plug 320. At this time, the user can pull the protective filter cartridge 330 downward through the plug 320 to remove it for cleaning, thereby achieving the purpose of protection and quick disassembly and cleaning.
