Description

Technical Field

[0001] This utility model relates to the field of water quality testing devices, and in particular to a portable water quality testing device. Background Technology

[0002] Water quality testing devices are used to sample water bodies and then analyze and monitor various physical, chemical, and biological parameters in the water. They can help ensure the safety of water sources and compliance with hygiene standards, and are widely used in environmental monitoring, drinking water treatment, industrial processes, and scientific research.

[0003] However, existing water quality testing devices require multiple sampling points in the water body, necessitate numerous auxiliary devices, involve frequent operations, and have a certain error rate. They are also very inconvenient to use, increasing the time delay and complexity of water quality testing.

[0004] Therefore, to address the issues of numerous auxiliary devices required for water quality testing and sampling, frequent operations, a certain error rate in sampling, and insufficient portability, a portable water quality testing device can be designed. Utility Model Content

[0005] To overcome the problems of numerous auxiliary equipment required for water quality testing and sampling, frequent operations, a certain error rate in sampling, and lack of portability.

[0006] The technical solution of this utility model is as follows: a portable water quality testing device, comprising a handheld handle, a mounting frame, an electric reel, a connecting frame, a mounting frame, a water sample collection assembly, and a float plate; a "door"-shaped mounting frame is fixedly connected to the front end of the handheld handle; an electric reel for launching and retrieving the water quality testing device is installed inside the mounting frame; one end of the electric reel's wire rope is fixedly connected to the connecting frame; a mounting frame is provided at the front end of the connecting frame; a water sample collection assembly for collecting water samples at different depths is installed inside the mounting frame; the water sample collection assembly includes push rod group A, push rod group B, a moving plate, a piston column, and a sampling tube; push rod group A and push rod group B are respectively fixed to the upper and lower ends of the mounting frame; a moving plate located inside the mounting frame is installed at the front end of the piston rods of push rod group A and push rod group B; a piston column is fixedly connected to the front end of the moving plate; a sampling tube is sleeved on the outside of the piston column; symmetrical float plates are provided on the top of the mounting frame to support the water sample collection assembly and prevent it from sinking.

[0007] Preferably, in the first step, the water quality testing device adopts a handheld design. When taking samples, the mounting frame is separated from the connecting frame, and the electric reel releases the steel wire rope of the pre-throwing distance.

[0008] The second step involves the testing personnel forcefully throwing the water sample collection component towards the target water area to be tested. Once the water sample collection component enters the water, the float supports it to prevent it from sinking to the bottom, thus avoiding the absorption of sludge during sampling.

[0009] The third step involves remotely activating push rod group A and push rod group B after the water sample collection assembly has stabilized. Push rod group A and push rod group B move the moving plate backward, simultaneously moving the pistons in the three sampling tubes at different positions backward. When the pistons in the sampling tubes are pulled back, they create negative pressure, drawing the water sample into the sampling tubes. Each set of sampling tubes has two sampling tubes, one as the main sampling tube and one as a backup sampling tube. This provides backup data in case the sample in the main sampling tube is unqualified or damaged, greatly improving the sampling success rate.

[0010] The fourth step involves the electric reel winding up the water sample collection assembly after sampling. The water sample is then simply rinsed, reassembled, and carried to the next testing location.

[0011] Preferably, an anti-slip ring is fixedly connected to the upper rear side of the hand handle to prevent the operator from slipping out of the water quality testing device; anti-slip pads are fixedly connected to both the upper and lower ends of the hand handle to increase the friction of the hand contact surface; the operator needs to put his hand into the anti-slip ring of the hand handle and grasp the anti-slip pad area, which increases the friction of the hand contact surface and prevents the water quality testing device from slipping out of the hand when moving.

[0012] Preferably, a magnetic block A is fixedly connected to the front end of the mounting frame; a magnetic block B is fixedly connected to the rear end of the connecting frame; magnetic block B and magnetic block A are connected by adsorption; the two parts of the water quality testing device are connected by magnetic block A and magnetic block B, which makes it very convenient and quick to separate and assemble the water quality testing device.

[0013] As a preferred option, the piston rod and sampling tube are installed in matching positions; the sampling tubes are all fixed to the front end of the mounting frame.

[0014] As a preferred embodiment, the water sample collection assembly also includes a limiting slider and a limiting groove; limiting grooves are provided at both ends of the mounting frame; limiting sliders are fixedly connected to both ends of the moving plate; the limiting slider and the limiting groove are slidably connected; thus ensuring the stability of the water quality testing device when sampling in water.

[0015] Preferably, positioning rings are fixedly connected to both ends of the mounting frame; detachable locking buckles are fastened to the outside of the positioning rings; the locking buckles are connected to the float via hanging ropes; depending on the sampling requirements, hanging ropes of different lengths can be replaced to adjust the distance between the water surface and the water sample collection component.

[0016] The beneficial effects of this utility model are:

[0017] This utility model features a handheld design, making it easy to move and use a water quality testing device. It is highly portable and designed for separate use. During sampling, the operator forcefully throws the water sample collection component towards the target water area. Once in the water, a float supports the component to prevent it from sinking and to avoid absorbing sludge during sampling. The negative pressure generated by the collection component draws the water sample into three sets of sampling tubes at different locations. Each set has two tubes: a main tube and a backup tube. This provides backup data should the main tube sample be unqualified or damaged, greatly improving the success rate and depth diversity of the sampling. After sampling, an electric reel winds up the water sample collection component, making the operation very convenient and quick. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-4This utility model provides an embodiment: a portable water quality testing device, including a handheld handle 1, a mounting frame 2, an electric reel 3, a connecting frame 4, a mounting frame 5, a water sample collection assembly, and a float 7; the front end of the handheld handle 1 is fixedly connected to the "door"-shaped mounting frame 2; the inner side of the mounting frame 2 is equipped with an electric reel 3 for launching and retracting the water quality testing device; one end of the steel wire rope of the electric reel 3 is fixedly connected to the connecting frame 4; the front end of the connecting frame 4 is provided with the mounting frame 5; the inner side of the mounting frame 5 is equipped with a water sample collection assembly for collecting water samples at different depths; the water sample collection assembly includes a push rod assembly A601, a push rod assembly B602, a moving plate 603, a piston column 604, and a sampling tube 605; the push rod assembly A601 and the push rod assembly B602 are respectively fixed on the mounting frame 5. The upper and lower ends; the piston rods of push rod assembly A601 and push rod assembly B602 are equipped with a movable plate 603 located inside the mounting frame 5; the front end of the movable plate 603 is fixedly connected to a piston column 604; a sampling tube 605 is sleeved on the outside of the piston column 604; symmetrical float plates 7 are set on the top of the mounting frame 5 to support the water sample collection component and prevent it from sinking; an anti-slip ring 8 is fixedly connected to the rear side of the upper end of the hand handle 1 to prevent the operator from slipping out of the water quality testing device; anti-slip pads 9 are fixedly connected to both the upper and lower ends of the hand handle 1 to increase the friction of the hand contact surface; the operator needs to put his hand into the anti-slip ring 8 of the hand handle 1 and hold the area of ​​the anti-slip pad 9, which increases the friction of the hand contact surface and prevents the water quality testing device from slipping out of the hand when moving.

[0025] Please see Figure 3 In this embodiment, a magnetic block A10 is fixedly connected to the front end of the mounting frame 2; a magnetic block B11 is fixedly connected to the rear end of the connecting frame 4; the magnetic block B11 and the magnetic block A10 are connected by adsorption; the two parts of the water quality detection device are magnetically connected by the magnetic blocks A10 and B11, which makes it very convenient and quick to separate and assemble the water quality detection device; the piston column 604 and the sampling tube 605 are installed in matching positions; the sampling tubes 605 are all fixed to the front end face of the mounting frame 5; the water sample collection assembly also includes a limiting slider 606 and a limiting groove 607; the mounting frame 5 has limiting grooves 607 at both ends; the moving plate 603 has limiting sliders 606 fixedly connected to both ends; the limiting sliders 606 and the limiting grooves 607 are slidably connected; ensuring the stability of the water quality detection device when sampling in water.

[0026] Please see Figure 4 In this embodiment, positioning rings 12 are fixedly connected to both ends of the mounting frame 5; detachable buckles 13 are fastened to the outside of the positioning rings 12; the buckles 13 are connected to the float 7 by a hanging rope 14; according to the sampling requirements, different lengths of hanging ropes 14 can be replaced to adjust the distance between the water surface and the water sample collection component.

[0027] When working, the first step is that the water quality testing device adopts a handheld design. The operator needs to put his hand into the anti-slip ring 8 of the handheld handle 1 and hold the anti-slip pad 9 area. This increases the friction of the hand contact surface, which may cause the water quality testing device to slip out of the hand when moving. When taking a sample, the mounting frame 2 and the connecting frame 4 are separated by magnetic attraction between magnetic block A10 and magnetic block B11. The electric reel 3 releases the wire rope of the pre-throw distance.

[0028] The second step involves the testing personnel forcefully throwing the water sample collection component towards the target water area. Once the component enters the water, the float 7 supports it to prevent it from sinking and avoids the absorption of sludge during sampling.

[0029] Third, after the water sample collection assembly is stable, remotely start push rod group A601 and push rod group B602. Push rod group A601 and push rod group B602 drive the moving plate 603 to move backward, and at the same time, the piston column 604 in the three sampling tubes 605 at different positions moves backward. When the piston column 604 of the sampling tube 605 is pulled back, it creates negative pressure and draws the water sample into the sampling tube 605. Each set of sampling tubes 605 has two sampling tubes 605, one as the main sampling tube 605 and one as the backup sampling tube 605. This can provide backup data if the sample in the main sampling tube 605 is unqualified or damaged, which greatly improves the sampling success rate.

[0030] The fourth step is to reel in the water sample collection component after sampling is completed. After extracting the water sample, it is simply rinsed, reassembled, and carried to the next testing location.

[0031] According to the testing and sampling requirements, the buckle 13 can be removed from the positioning ring 12 and the hanging rope 14 of different lengths can be replaced to adjust the distance between the water surface and the water sample collection component.

[0032] Through the above steps, the handheld design facilitates the movement of the water quality testing device, making it highly portable. The device is designed for separate use; during sampling, the operator forcefully throws the water sample collection component towards the target water area. The component enters the water, and the float 7 supports it to prevent it from sinking and to avoid absorbing sludge during sampling. The negative pressure generated by the water sample collection component draws the water sample into three sets of sampling tubes 605 at different locations. Each set of tubes 605 has two tubes: one main tube and one backup tube. This provides backup data should the main tube sample be unqualified or damaged, greatly improving the sampling success rate and depth diversity. After sampling, the electric reel 3 winds up the water sample collection component, making the operation very convenient and quick.
