Description

Technical Field

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

[0002] Water quality monitoring is the process of monitoring and determining the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality. Water quality monitoring methods can be divided into on-site measurement and sampling measurement. During on-site measurement, the surveyor needs to carry the water quality monitoring device to the water area that needs to be monitored and conduct on-site measurement in the target water area. This not only avoids the problem of secondary contamination of water samples during the sampling process, but also enables measurements to be conducted at various locations and depths in the target water area, thereby obtaining a large amount of real and effective data, which is convenient for researchers' experimental research;

[0003] According to the Chinese patent announcement number: CN218727193U, a portable water quality monitoring device is disclosed, which is provided with floats on the front and rear walls of the monitoring box body. The two sets of floats can ensure that the whole device floats on the water surface and will not sink to the bottom of the water to cause damage. A water quality monitoring probe is provided at the bottom of the monitoring box body, and a lifting device that can lift the water quality monitoring probe is provided in the inner cavity of the monitoring box body. When working, the water quality monitoring probe can be moved out of the monitoring box body by the lifting device to perform water quality sampling. When the sampling work is completed, the water quality monitoring probe can be stored in the monitoring box body by the lifting device to avoid damage to the water quality monitoring probe. By manually pulling the wristband, the entire water quality monitoring device can be conveniently carried; in this technical solution, the wristband does not have an auxiliary fixing structure, which makes it easy for the monitoring box body to slip from the hand and collide with the ground, thereby causing damage and affecting the service life of the monitoring box. For this reason, we propose a portable water quality monitoring device. Utility Model Content

[0004] The purpose of the utility model is to provide a portable water quality monitoring device to solve the problems in the background technology.

By setting the limit rod, the L-shaped plate 1 and the L-shaped plate 2 can be limited to prevent the L-shaped plate 1 and the L-shaped plate 2 from rotating with the bidirectional screw, thereby ensuring the normal movement of the L-shaped plate 1 and the L-shaped plate 2.

[0008] Preferably, a clamping pad is fixedly installed on the inner side of the splint, and the material of the clamping pad is silicone. By providing the clamping pad, hard contact between the splint and the wrist of the person is avoided, thereby improving the comfort of the person when the splint is clamped.

[0009] Preferably, the outer sleeve of the buoyancy box is provided with a protective cover, a positioning rod is fixedly installed on the inner side of the protective cover, a fixing plate is fixedly installed on the top of the monitoring box body, a rod hole 1 is opened on the fixing plate, the positioning rod movably passes through the fixing plate through the rod hole 1, a magnetic ring 1 is fixedly sleeved on the outer wall of the positioning rod, a magnetic ring 2 is fixedly installed on the inner wall of the rod hole 1, and the magnetic ring 2 is magnetically sleeved on the outer wall of the magnetic ring 1.

[0010] Preferably, the outer wall surface of magnetic ring one and the inner wall surface of magnetic ring two have opposite magnetic properties. By arranging magnetic ring one and magnetic ring two, the stability of the positioning rod in rod hole one can be improved, thereby ensuring the installation stability of the protective cover.

[0011] Preferably, the protective cover is made of transparent PVC material, and the number of the positioning rods and the number of the fixing plates are both four.

[0012] The utility model provides a portable water quality monitoring device. The portable water quality monitoring device has the following beneficial effects:

[0013] (1) The portable water quality monitoring device can be equipped with a carrying mechanism so that the clamp can clamp the wrist of the person, thereby improving the firmness of the person when taking the monitoring box body, avoiding the problem that the monitoring box body slips from the hand and causes damage after colliding with the ground, ensuring the safety and stability of the monitoring box body when carrying, and facilitating the person to carry;

[0014] (2) The portable water quality monitoring device can provide a protective cover to the buoyancy box to prevent the buoyancy box from being scratched by collision, which would render the buoyancy box unusable and affect the normal monitoring and use of the monitoring box body. In addition, the protective cover can be easily disassembled and assembled by personnel through the cooperation of the positioning rod, magnetic ring 1, fixing plate, rod hole 1 and magnetic ring 2, which is highly practical.

[0026] The carrying mechanism 4 includes a connecting frame 401, an L-shaped plate 1 404, and an L-shaped plate 2 405. The connecting frame 401 is fixedly installed on the top of the monitoring box body 1. The inner wall of the connecting frame 401 is rotatably connected to a bidirectional screw 402 through a bearing. The outer wall of the bidirectional screw 402 is fixedly sleeved with a grip sleeve 403. The L-shaped plate 1 404 and the L-shaped plate 2 405 are respectively threadedly sleeved on the outer wall of the bidirectional screw 402 near both ends. A clamping plate 406 is fixedly installed on the inner side of the top of the L-shaped plate 1 404 and the L-shaped plate 2 405. A limiting rod 408 is fixedly installed on the inner wall of the connecting frame 401. A rod hole 2 409 is opened near the bottom of the L-shaped plate 1 404 and the L-shaped plate 2 405. The limiting rod 408 movably passes through the rod hole 2 409 and penetrates the L-shaped plate 1 404 and the L-shaped plate 2 405.

[0027] Specifically, when a person picks up and carries the monitoring box body 1, he or she can hold the grip 403 and then rotate the bidirectional screw 402. The bidirectional screw 402 drives the L-shaped plate 1 404 and the L-shaped plate 2 405 to approach each other. The L-shaped plate 1 404 and the L-shaped plate 2 405 drive the splint 406 thereon to approach the person's wrist, and finally the splint 406 clamps the person's wrist, thereby improving the firmness of the person when picking up the monitoring box body 1, avoiding the problem that the monitoring box body 1 slips from the hand and collides with the ground, causing damage, thereby ensuring the safety and stability of the monitoring box body 1 when being carried, and facilitating people to carry it.
