Description

Technical Field

[0001] This utility model relates to the technical field of water quality testing equipment, specifically a portable water quality heavy metal detector. Background Technology

[0002] Water is the source of life and a resource upon which people depend for survival. Therefore, water conservation and water quality analysis are of paramount importance. Water quality includes drinking water, surface water, and sewage, and corresponding water quality testing includes drinking water testing, surface water testing, and sewage testing. By testing water quality, we can determine whether water is polluted, which is inextricably linked to our health and the environment. At the same time, in the processes of mining, smelting, manufacturing products, and discharging wastewater and exhaust gases, some heavy metals that endanger human health are emitted. Currently, water quality testing personnel need to conduct laboratory analysis, often using the traditional method of atomic absorption spectrophotometry.

[0003] Existing heavy metal detectors are typically installed inside a housing with a handle at the top for portability. However, when testing in remote water sources, the inconvenient road conditions require personnel to carry the detector over long distances using the handle, which can easily lead to hand fatigue, soreness, and even skin abrasions due to prolonged strain. Therefore, we provide a portable water quality heavy metal detector to address these issues. Utility Model Content

[0009] The sealing plate has two sets of symmetrical insertion holes on its front side and two sets of symmetrical strip grooves on its front side. The two ends of the two shoulder straps pass through the two sets of symmetrical strip grooves respectively. One end of the shoulder strap passing through the upper side of the strip groove is fixedly connected to the slide plate inside the upper sliding cavity, and the other end of the shoulder strap passing through the lower side of the strip groove is fixedly connected to the slide plate inside the lower sliding cavity.

[0010] Furthermore, the back sides of both fixed frames are fixedly connected to the rear side of the inner wall of the storage cavity, and the two first elastic members are sleeved on the outside of the slide rod, with the ends of the two first elastic members away from the slide plate fixedly connected to the inner wall of the sliding cavity.

[0011] Furthermore, the outer surface of the plug rod is slidably connected to the inner wall of the circular groove, the back of the sealing plate is fixedly connected to the front of the heavy metal detector housing, and both sets of plug holes are plugged into the plug rod.

[0012] Furthermore, a handle mechanism is provided on the top of the heavy metal detector housing. The handle mechanism includes a handle, and sliding grooves are provided at both ends of the handle. A limit ring is fixedly connected to the bottom of the inner sidewall of the sliding groove.

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this portable water heavy metal detector has the following advantages:

[0018] I. This portable water quality heavy metal detector, by pulling out a sealing plate and limiting the two ends of the shoulder strap through the plug rod and plug hole, enables the device to be carried on the back. When the shoulder strap is not in use, it does not affect the portability of the device when carried by hand. This solves the problem of existing heavy metal detectors in remote water sources where, due to inconvenient road access, the testing personnel need to carry the heavy metal detector over long distances by hand, which can easily cause fatigue, soreness, and even skin abrasions to the hands of the testing personnel due to long-term stress.

[0019] II. When this portable water quality heavy metal detector is carried by the handle, the elasticity of the third elastic element causes the sliding plate to slide up and down inside the sliding groove as the box moves. At the same time, the sliding column slides up and down under the positioning of the limiting ring, and the connecting rod moves in the same direction as the sliding column. This causes the heavy metal detector box to move up and down, thereby reducing the impact on the arm caused by the up and down movement of the heavy metal detector box. This achieves the purpose of the device to effectively reduce the impact on the arm caused by the up and down movement of the box. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5As shown, this utility model provides a technical solution: a portable water quality heavy metal detector, including a heavy metal detector housing 1. A storage cavity 2 is opened on the front of the heavy metal detector housing 1. A shoulder strap mechanism 3 is arranged inside the storage cavity 2. The shoulder strap mechanism 3 includes two mutually symmetrical fixing frames 301, a sealing plate 309, and two mutually symmetrical shoulder straps 312. Two mutually symmetrical sliding cavities 302 are opened on the front of each of the two fixing frames 301. Two mutually symmetrical sliding rods 303 are fixedly connected to the inner sidewalls of each of the two sliding cavities 302. A sliding plate 304 is slidably connected to the two sliding rods 303. Two mutually symmetrical first elastic elements 305 are fixedly connected to the sliding plate 304. A circular groove 306 is opened on the front of the sliding plate 304. A second elastic element 307 is fixedly connected to the rear side of the inner sidewall of the circular groove 306. A plug-in rod 308 is fixedly connected to the front end of the second elastic element 307. Two sets of mutually symmetrical... The connector 310 is provided. Two sets of symmetrical strip-shaped grooves 311 are provided on the front of the sealing plate 309. The two ends of the two shoulder straps 312 pass through the two sets of symmetrical strip-shaped grooves 311 respectively. One end of the shoulder strap 312 passing through the upper side of the strip-shaped groove 311 is fixedly connected to the slide plate 304 inside the upper sliding cavity 302. The other end of the shoulder strap 312 passing through the lower side of the strip-shaped groove 311 is fixedly connected to the slide plate 304 inside the lower sliding cavity 302. Two fixing frames... The back of 301 is fixedly connected to the rear side of the inner wall of the storage cavity 2. The two first elastic elements 305 are sleeved on the outside of the slide rod 303. The ends of the two first elastic elements 305 away from the slide plate 304 are fixedly connected to the inner wall of the sliding cavity 302. The outer surface of the plug rod 308 is slidably connected to the inner wall of the circular groove 306. The back of the sealing plate 309 is fixedly connected to the front of the heavy metal detector housing 1. The two sets of plug holes 310 are plugged into the plug rod 308.

[0029] The first elastic element 305 and the second elastic element 307 are preferably made of springs. The plug rod 308 is preferably cylindrical. The plug hole 310 is preferably a round hole. The axis of the cylindrical plug rod 308 and the axis of the round hole 310 are both in the same longitudinal vertical plane.

[0030] By pulling the two symmetrical shoulder straps 312 in front of the sealing plate 309, the two symmetrical sliding plates 304 are moved away from each other. Simultaneously, the insertion rod 308 moves in the same direction as the sliding plate 304. When the insertion rod 308 is aligned with the insertion hole 310, the second elastic element 307 pushes the insertion rod 308 into the insertion hole 310, limiting the position of the shoulder straps 312. This enables the device to carry passengers. When the shoulder straps are not in use, pressing the insertion rod 308 releases the limitation imposed by the insertion hole 310 on the insertion rod 308. Under the elastic action of the first elastic element 305, the carrying strap 312 quickly returns to its original position, so that the carrying strap does not affect the portability of the device when it is carried by hand. This achieves the purpose of the device having a carrying function, and the portability of the device when it is not carried by hand is not affected when the carrying function is not used. This solves the problem that in the prior art, when heavy metal detectors are used to detect some remote water sources, due to inconvenient road access, the detection personnel need to carry the heavy metal detector over a long distance by the handle, and the detection personnel's hands are prone to fatigue, soreness and even skin abrasion due to long-term force.

[0031] A handle mechanism 4 is provided on the top of the heavy metal detector housing 1. The handle mechanism 4 includes a handle 401. Both ends of the handle 401 are provided with sliding grooves 402. A limiting ring 403 is fixedly connected to the bottom of the inner sidewall of the sliding groove 402. A sliding column 404 is slidably connected to the inner sidewall of the limiting ring 403. A sliding disk 405 is fixedly connected to the top of the sliding column 404. The outer surface of the sliding disk 405 is slidably connected to the inner sidewall of the sliding groove 402. A third elastic element 406 is fixedly connected to the lower surface of the sliding disk 405. The bottom end of the third elastic element 406 is fixedly connected to the outer surface of the limiting ring 403. The third elastic element 406 is sleeved on the outside of the sliding column 404. A connecting rod 407 is fixedly connected to the bottom end of the sliding column 404. A connecting plate 408 is fixedly connected to the bottom end of the connecting rod 407. The lower surface of the connecting plate 408 is fixedly connected to the upper surface of the heavy metal detector housing 1.

[0032] The material of the third elastic element 406 here is preferably a spring, and the handle 401 here is provided with a rubber sleeve on the outside.

[0033] When the device is carried by the handle, under the elastic action of the third elastic element 406, the sliding plate 405 moves up and down inside the sliding groove 402 as the box moves, and at the same time, the sliding column 404 moves up and down under the positioning of the limiting ring 403. Simultaneously, the connecting rod 407 moves in the same direction as the sliding column 404, and the heavy metal detector box 1 moves up and down. This reduces the impact force on the arm when the heavy metal detector box 1 moves up and down, thus achieving the purpose of the device to effectively reduce the impact of the box's undulation on the arm.

[0034] Working principle: In use, by pulling out the two symmetrical shoulder straps 312 in front of the sealing plate 309, the two symmetrical sliding plates 304 are moved away from each other. Simultaneously, the insertion rod 308 moves in the same direction as the sliding plate 304. When the insertion rod 308 is aligned with the insertion hole 310, the second elastic element 307 causes the insertion rod 308 to insert into the insertion hole 310, limiting the position of the shoulder straps 312 and enabling the device to carry the device. When the shoulder straps are not in use, pressing the insertion rod 308 releases the limitation imposed by the insertion hole 310, and the first elastic element 305 causes the shoulder straps 312 to quickly return to their original position, ensuring that the shoulder straps do not interfere with the device. The device is portable when carried by hand, achieving the purpose of having a carrying function, and the portability of the device when carried by hand is not affected when the carrying function is not used. When carrying the device by the handle, under the elastic action of the third elastic element 406, the sliding plate 405 moves up and down inside the sliding groove 402 as the case moves, thereby driving the sliding column 404 to move up and down under the positioning of the limiting ring 403. At the same time, the connecting rod 407 moves in the same direction as the sliding column 404, and drives the heavy metal detector case 1 to move up and down. This can reduce the impact force on the arm when the heavy metal detector case 1 moves up and down, thus achieving the purpose of the device to effectively reduce the impact of the case's undulation on the arm.
