Description

Technical Field

[0001] This utility model belongs to the field of water quality testing, specifically a portable water quality testing sampling box. Background Technology

[0002] Water quality testing sampling refers to obtaining samples from a water body at a specific time and location for subsequent analysis and testing. The purpose of sampling is to assess the degree of water pollution, monitor changes in water quality, and ensure that the water body meets relevant safety standards.

[0003] In existing technologies, when it is necessary to sample and test the water quality of different water areas or different time periods in the same water area, the water sample is generally collected by a sampling device and then transported to a water quality analyzer for water quality testing. The operation is relatively complicated. Moreover, the sampling device can only sample one set of water samples at a time. The water sample inside the device needs to be processed before sampling the second set of samples, which seriously affects the sampling efficiency. Furthermore, the sampling head of the sampling device in the existing technology is mostly exposed to the outside world without a protective mechanism. This will cause the sampling head to be exposed to the outside world for a long time, making it susceptible to external pollution or collisions with external objects, which will reduce its service life.

A reciprocating screw is rotatably connected inside the housing and above the motor. One end of the reciprocating screw is fixedly connected to a second synchronous pulley. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt drive. A connecting plate is connected to the outside of the reciprocating screw through a screw nut pair. The top of the connecting plate is fixedly connected to a sliding sleeve.

[0008] In a preferred embodiment, the top of the turntable is provided with drain outlets at equal intervals, and the multiple drain outlets and multiple sampling cups are staggered. The bottom of the box is fixedly connected to a water outlet pipe, the turntable is rotatably connected to the water outlet pipe, the water outlet pipe is connected to the multiple drain outlets through an internal channel, and a solenoid valve is installed at the bottom of the water outlet pipe.

[0009] In a preferred embodiment, a water pump is installed at the bottom of the sampling tube, and a funnel cap is installed at the top of each of the sampling cups.

[0010] In a preferred embodiment, a rotating plate is rotatably connected to the outer side of the housing near the sliding sleeve, and a torsion spring is provided at the rotatable connection between the rotating plate and the housing.

[0013] The beneficial effects of this utility model are as follows:

[0014] This device can collect water samples from different water sources using multiple sampling cups. It also facilitates the collection of water samples from the same water source at different times, avoiding the inconvenience of similar sampling devices that can only collect one set of water samples at a time and require frequent emptying of the collected samples before continuing sampling. This improves the accuracy and efficiency of subsequent water quality testing. Furthermore, after sampling, the sampling head can be stored inside the housing, preventing contamination or damage from external objects due to prolonged exposure, thus enhancing the device's safety.

[0032] Please see Figure 1-5 A portable water quality testing sampling box includes a box body 1. A sampling tube 2 is fixedly connected to one side of the inside of the box body 1. A sliding sleeve 3 is slidably connected to the outside of the sampling tube 2. A corrugated pipe 4 is installed on one side of the bottom of the sliding sleeve 3. A sampling head is fixedly connected to the bottom of the corrugated pipe 4. A turntable 5 is rotatably connected to the bottom of the inner wall of the box body 1. Sampling cups 6 are equidistantly arranged on the top of the turntable 5. A water quality analyzer 7 is fixedly connected to the upper inside of the box body 1. A transmission assembly is provided inside the box body 1.

[0033] Specifically, the transmission assembly includes a first bevel gear 8 and a linkage unit. The first bevel gear 8 is fixedly connected to the lower outer side of the turntable 5. A second bevel gear 9 is rotatably connected to one side of the bottom of the inner wall of the housing 1 via a rotating shaft. The first bevel gear 8 and the second bevel gear 9 are meshed together. A motor 10 is fixedly connected to one side of the inner side of the housing 1 via a mounting block. The output end of the motor 10 is fixedly connected to the second bevel gear 9. The sliding sleeve 3 can be moved through the linkage unit. The linkage unit includes a first synchronous pulley 11, which is fixedly connected to the outside of the output end of the motor 10. A reciprocating screw 12 is rotatably connected inside the housing 1 and above the motor 10. A second synchronous pulley 13 is fixedly connected to one end of the reciprocating screw 12. The first synchronous pulley 11 and the second synchronous pulley 13 are connected by a synchronous belt 14. A connecting plate 15 is connected to the outside of the reciprocating screw 12 via a screw nut pair. The top of the connecting plate 15 is fixedly connected to the sliding sleeve 3.

[0034] Through the above technical solution, the handle 24 facilitates the carrying of the device by staff, and the casters facilitate its movement, thereby improving the flexibility and portability of the device. When water sampling is required, the motor 10 is started via the control panel 23. The output of the motor 10 drives the second bevel gear 9 and the first synchronous pulley 11 to rotate. The second bevel gear 9, through meshing, drives the first bevel gear 8 and the turntable 5 to rotate. The turntable 5 moves one of the sampling cups 6 at the top to below the sampling tube 2. At the same time, the first synchronous pulley 11 drives the second synchronous pulley 13 and the reciprocating screw 12 to rotate via the synchronous belt 14. The reciprocating screw 12 drives the connecting plate 15 and the sliding sleeve 3 to move to one side until the sliding sleeve 3 drives the bellows 4 to move to the outside of the housing 1 and pushes the rotating plate 20 upward to open. At the same time, the torsion spring is compressed, causing it to deform. At this time, the motor 10 is turned off, and the operator can then pull the sampling head into the water body by stretching the bellows 4. Then, the water pump 18 is started through the control panel 23 to pump water into the current sampling cup 6. After the water body sampling is completed, the motor 10 is started again, and the turntable 5 continues to rotate through the same operation as above, which in turn drives the current sampling cup 6 to continue rotating, and drives the rear... The drain outlet 16 rotates to the bottom of the sampling tube 2, allowing residual water droplets at the bottom of the sampling tube 2 to be collected, preventing them from dripping everywhere and being difficult to clean. Simultaneously, the reciprocating screw 12, through its reciprocating connection with the connecting plate 15, drives the sliding sleeve 3 back to its original position, thus retracting the sliding sleeve 3. This prevents the sampling head at the bottom of the sliding sleeve 3 from being exposed to the outside environment for extended periods, avoiding contamination or damage from collisions with external objects, thus improving the safety of the device. After the sliding sleeve 3 returns to the inside of the housing 1, the return force of the torsion spring causes the rotating plate 20 to reseal the housing 1. To prevent external dust from entering the interior of the housing 1, this device can collect water samples from different water sources using multiple sampling cups 6. It also facilitates the collection of water samples from different time periods within the same water body, avoiding the inconvenience of similar sampling devices that can only sample one set of water samples at a time and then frequently pour out the collected water samples before continuing sampling. This improves the accuracy and efficiency of subsequent water quality testing. Furthermore, after sampling, the sampling head can be stored inside the housing 1, preventing the sampling head from being exposed to the outside environment for a long time and thus avoiding contamination or damage caused by collisions with external objects, thereby improving the safety of the device.

[0035] Specifically, the top of the turntable 5 is provided with drain outlets 16 at equal intervals, and the multiple drain outlets 16 and multiple sampling cups 6 are staggered. The bottom of the box 1 is fixedly connected to the water outlet pipe 17, and the turntable 5 and the water outlet pipe 17 are rotatably connected. The water outlet pipe 17 and the multiple drain outlets 16 are connected through an internal channel. The bottom of the water outlet pipe 17 is equipped with a solenoid valve, the bottom of the sampling tube 2 is equipped with a water pump 18, and the top of the multiple sampling cups 6 is equipped with a funnel cover 19.

[0036] With the above technical solution, the residual water droplets collected by the drain outlet 16 can slide into the outlet pipe 17. The collected residual water droplets can be discharged by opening the solenoid valve. The funnel cover 19 facilitates the entry of the collected water sample and avoids the problem of water sample splashing out when the tank 1 moves.

[0037] Specifically, a rotating plate 20 is rotatably connected to the outside of the housing 1 near the sliding sleeve 3. A torsion spring is provided at the rotatable connection between the rotating plate 20 and the housing 1. A lifting detection head 21 is installed on the outside of the water quality analyzer 7 away from the sampling tube 2. The diameter of the second bevel gear 9 is smaller than the diameter of the first bevel gear 8. A door 22 is installed on the outside of the housing 1. A control panel 23 is installed on one side of the outside of the door 22. Handles 24 are fixedly connected to both sides of the top of the housing 1. Universal wheels are symmetrically installed on both sides of the bottom of the housing 1. The water quality analyzer 7, the motor 10, and the water pump 18 are all electrically connected to the control panel 23.

[0038] Through the above technical solution, by controlling the lifting detection head 21 to descend and probe into the corresponding sampling cup 6, the water sample inside can be detected, realizing the integration of sampling and detection, further improving the practicality of the device. By opening the box door 22, the sampling cup 6 inside can be taken out, thereby processing the water sample inside the sampling cup 6, and the sampling cup 6 can be cleaned at the same time. The control panel 23 allows the staff to quickly control the water quality detector 7, motor 10 and water pump 18.

[0039] In use, the handle 24 facilitates carrying the device, and the casters make it easy to move, thus improving its flexibility and portability. When water sampling is required, the motor 10 is started via the control panel 23. The output of the motor 10 drives the second bevel gear 9 and the first synchronous pulley 11 to rotate. The second bevel gear 9, through meshing, drives the first bevel gear 8 and the turntable 5 to rotate. The turntable 5 moves one of the sampling cups 6 at the top to below the sampling tube 2. At the same time, the first synchronous pulley 11 drives the second synchronous pulley 13 and the reciprocating screw 12 to rotate via the synchronous belt 14. This causes the reciprocating screw 12 to move the connecting plate 15 and the sliding sleeve 3 to one side until the sliding sleeve 3 drives the bellows 4. The device moves to the outside of housing 1 and pushes the rotating plate 20 upwards, simultaneously compressing the torsion spring to deform it. At this point, motor 10 is turned off, and the operator can then use the extended bellows 4 to drive the sampling head into the water body. The water pump 18 is then started via control panel 23 to pump water into the current sampling cup 6. After water sampling is complete, motor 10 is restarted, and the turntable 5 continues to rotate through the same process, causing the current sampling cup 6 to continue rotating. This also rotates the drain outlet 16 to the bottom of the sampling tube 2, allowing residual water droplets at the bottom of the sampling tube 2 to be collected, preventing them from dripping and becoming difficult to clean. Simultaneously, the reciprocating screw 12 can be connected to... The reciprocating connection of plate 15 drives the sliding sleeve 3 to move back to its original position, thereby completing the storage of the sliding sleeve 3. This avoids the sampling head at the bottom of the sliding sleeve 3 from being exposed to the outside environment for a long time, which could lead to contamination or damage from collisions with external objects, thus improving the safety of the device. After the sliding sleeve 3 moves back into the box 1, the return force of the torsion spring can drive the rotating plate 20 to reseal the box 1, preventing external dust from entering the interior of the box 1. This device can collect water samples from different water sources using multiple sampling cups 6. It can also facilitate the collection of water samples from the same water source at different times, avoiding the problem of similar sampling devices that can only sample one set of water samples at a time and then frequently pour out the collected water samples before continuing. The simplified sampling process improves the accuracy and efficiency of subsequent water quality testing. After sampling, the sampling head can be retracted into the housing 1, preventing contamination or damage from prolonged exposure and impacts, thus enhancing safety. The drain outlet 16 collects residual water droplets, which then slide into the outlet pipe 17. Opening the solenoid valve discharges the collected droplets. The funnel cover 19 facilitates sample entry and prevents splashing during housing movement. By controlling the lifting detection head 21 to descend and penetrate the corresponding sampling cup 6, the water sample inside can be tested, achieving integrated sampling and testing.This further enhances the practicality of the device. By opening the door 22, the sampling cup 6 can be removed, allowing for the processing of the water sample inside. The sampling cup 6 can also be cleaned. The control panel 23 allows for convenient and quick control of the water quality analyzer 7, motor 10, and water pump 18 by the operator.

[0040] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
