Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a portable water quality detection device. Background Art

[0002] A water quality testing device is a specialized device used to analyze and evaluate the various physical, chemical, and biological properties of water. It can accurately measure water components (such as pH, heavy metal content, and microbial counts). When the safety of drinking water needs to be assessed, such as in residential water supply system inspections and field drinking water source assessments, water quality testing devices are used to determine whether the water contains harmful bacteria, viruses, excessive heavy metals, and other substances that endanger human health, ensuring that drinking water meets safety standards. In the field of environmental monitoring, whether it is natural water bodies such as rivers, lakes, and oceans, or polluted water bodies such as industrial wastewater and urban sewage, water quality testing devices are needed to monitor changes in water quality.

[0003] Water quality detection devices use sensors to sense physical parameters of water quality, such as temperature, turbidity, and conductivity. For example, optical sensors are used to measure turbidity based on the principle of light scattering or transmission to obtain intuitive physical state information of water quality. In the existing technology, due to interference from factors such as dust and floating objects in the external environment, some detection devices find it difficult to efficiently detect water quality. In order to eliminate these interference factors, the time period from sampling to outputting results in the detection process is extended, which reduces detection efficiency and the accuracy of detection data. Therefore, a portable water quality detection device is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3 The utility model provides an embodiment: a portable water quality detection device, including a box body 1, which serves as the outer shell and support structure of the entire device to protect the internal components from the influence of the external environment. The inner wall of the box body 1 is fixedly connected to a control console 2, which is responsible for coordinating the work of various components. The top of the console 2 is fixedly connected to a detection board 3, which serves to provide support for subsequent mechanisms and also serves to analyze and process the water quality detection data. The top of the detection board 3 is fixedly connected to an electric push rod 4, which is the power source for the entire device to take samples. The output end of the electric push rod 4 is fixedly connected to a drive plate 5, which is driven by the operation of the electric push rod 4 to lift and lower the drive plate 5.

[0033] The inside of the detection plate 3 is fixedly connected with a plurality of detection test tubes 6, which are used to store water samples to be tested, and the plurality of detection test tubes 6 simultaneously test the water quality and reflect the test data in the form of an average value, so that the test results are more accurate. The top of the detection test tube 6 is detachably connected with a sealing plug 7, which is used to seal the entire detection test tube 6 to prevent external impurities from entering the detection test tube 6 and causing inaccurate test results. The inner wall of the sealing plug 7 is slidably connected with a piston column 8, which is used to control the entire detection test tube 6 to take samples and release samples. The tops of the plurality of piston columns 8 are fixedly connected to the bottom of the driving plate 5, and the movement of the driving plate 5 drives the piston column 8 to move synchronously. The outer wall of the bottom of the piston column 8 contacts the inner wall of the detection test tube 6, so that the pressure in the detection test tube 6 is changed by the sliding of the piston column 8 on the inner wall of the detection test tube 6, thereby achieving the effect of automatic water absorption and discharge.

[0034] The bottom of the detection test tube 6 is fixedly connected to a water pipe 9, which is used to drain external water into a single detection test tube 6. The outer walls of multiple water pipes 9 are fixedly connected to the inside of the console 2 to fix the water pipe 9. The bottoms of multiple water pipes 9 are fixedly connected to a transport pipe 10, which is used to draw sufficient water samples into the detection device to accurately detect data. The outer walls of the two transport pipes 10 are fixedly connected to the inside of the console 2. The outer ends of the transport pipes 10 can be sealed by adding rubber plugs to prevent external pollutants from entering the interior of the detection sampling device. The top of the console 2 is fixedly connected to two reels 11, and the outer side of the reel 11 is provided with a docking hose 12. The reel 11 is used to store the docking hose 12 when the detection device is not needed. The two ends of the docking hose 12 are respectively provided with threads, thereby forming an intermediate docking mechanism, so that the transport pipe 10 can be docked with the subsequent mechanism. Two sampling heads 13 of different models are placed on the top of the console 2. The sampling heads 13 can be replaced according to different detection requirements to improve the detection effect of different water qualities.

[0035] The top of the console 2 is provided with a plurality of control buttons 14, which are used to control the various functions of the detection device. The top of the console 2 is provided with heat dissipation holes 15 to ensure that the device will not overheat during long-term operation. A display 16 is provided on the top of the console 2 to display the test results and other relevant parameter information. A box cover 17 is rotatably connected to one end of the top of the box body 1, and a soft pad 18 is fixedly connected to the inner wall of the box cover 17 to prevent damage to the internal components when the detection box is closed. It also plays a role in protecting the detection device from damage due to external vibrations during transportation. The outer wall of the box body 1 and the outer wall of the box cover 17 are provided with a box lock 27 for controlling the opening and closing of the entire detection box. The entire detection box can be opened by pulling out the pin on the box lock 27, which is convenient for use. The top of the box cover 17 is fixedly connected with a portable component for conveniently carrying the water quality detection device.

[0036] Reference Figure 1 、 Figure 4 、 Figure 5 The portable component includes a fixing bar 19, which is used to provide a support point for the subsequent mechanism. The outer wall of the fixing bar 19 is fixedly connected to two telescopic shells 20, and the telescopic shells 20 are used to provide a telescopic space and an extended track for the subsequent mechanism. The inner walls of the two telescopic shells 20 are slidably connected with a telescopic handle 21, and the entire handle mechanism is extended and retracted by sliding the telescopic handle 21 inside the telescopic shell 20, so that the handle mechanism is extended when the detection device needs to be moved, and the handle mechanism is retracted when it is not needed to be moved, so that the user can carry it with him. One end of the telescopic handle 21 is fixedly connected to a strap 25, which is used to prevent the handle from slipping when the user moves the detection device, causing the detection device to be damaged by falling.

[0037] Two springs 22 are fixedly connected to the interior of the telescopic handle 21. The springs 22 are used to provide a reset and locking force for the subsequent locking mechanism. The other end of the spring 22 is fixedly connected to a limit block 23. The limit block 23 is slidably connected to the inner wall of the telescopic handle 21. The limit block 23 is used to limit the movement direction and path of the subsequent mechanism. A locking ball 24 is fixedly connected to the top of the limit block 23. The outer wall of the locking ball 24 contacts the inner wall of the top of the telescopic shell 20. The contact and separation of the locking ball 24 with the opening at the top of the telescopic shell 20 can fix the extension length of the entire telescopic handle 21. A fastener 28 is threadedly connected to the outer wall of the telescopic shell 20. By rotating the fastener 28, the fastener 28 moves downward until it contacts the telescopic handle 21, thereby further tightening the extension length of the telescopic handle 21 through the action of friction, preventing the telescopic handle 21 from slipping when the mobile device is used. One side outer wall of the box cover 17 is fixedly connected to two universal wheels 26, so that the entire detection device can be easily moved on the ground without lifting, which is very convenient.

[0038] Working principle: When testing the water quality, by opening the box lock 27, the box body 1 and the box cover 17 are opened, the sampling head 13 and the docking hose 12 are taken out, and then the head of the transport pipe 10 is taken out, and the transport pipe 10, the docking hose 12, and the sampling head 13 are connected in turn, and then the electric push rod 4 is opened. The electric push rod 4 moves upward to drive the driving plate 5 to move upward, thereby driving the piston column 8 to move upward, so that a negative pressure is formed inside the test tube 6, thereby sucking the water sample to be tested. After the water sample to be tested is sucked, the water sample is tested by the detection module inside the detection board 3, and finally the detection data is comprehensively processed and displayed on the display screen. After the test is completed, the electric push rod 4 is opened again, so that the electric push rod 4 drives the driving plate 5 to descend, thereby driving the piston column 8 to discharge the water sample in the test tube 6, and then the inner wall of the test tube 6, the water pipe 9 and the inner wall of the transport pipe 10 are cleaned by absorbing clean water and discharged for the next test.

[0039] When the detection device needs to be moved, the entire detection device can be placed vertically so that the universal wheel 26 contacts the ground, and then the locking ball 24 is pressed to drive the limit block 23 to slide downward, thereby compressing the spring 22, and the fastener 28 is rotated at the same time to create a certain gap between the fastener 28 and the telescopic handle 21, so that the length of the entire handle can be freely adjusted by pulling the telescopic handle 21, and then the strap 25 is tied to the user's hand to prevent the entire detection device from slipping. When the length of the telescopic handle 21 is adjusted, since the locking ball 24 is not squeezed by the inner wall of the telescopic shell 20, the spring 22 recovers its deformation and drives the locking ball 24 to contact the telescopic shell 20 again, and then the fastener 28 is rotated in the opposite direction so that the bottom of the fastener 28 contacts the outer wall of the telescopic handle 21, thereby generating a certain friction force, which plays a reinforcing role.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
