Technical Field

[0001] The invention relates to the technical field of water quality detection equipment, and in particular to a portable water quality heavy metal detector. Background Art

[0002] Water is the source of life and a resource that people depend on for survival, so water conservation and water quality analysis are particularly important. Water quality includes drinking water, surface water, sewage, etc. The corresponding water quality testing includes drinking water testing, surface water testing and sewage testing, etc. By testing the water quality, we can determine whether the water is polluted, which is inextricably linked to our health and the environment. At the same time, in the process of mining, smelting, manufacturing products and discharging wastewater and exhaust gas, some heavy metals that endanger human safety are discharged. At present, the staff of the Water Quality Testing Department need to conduct chemical analysis, and the traditional method often used is atomic absorption spectrophotometry.

[0003] An existing portable water quality heavy metal detector generally includes a detection box, in which a detector is installed, and a handle is installed on the detection box, by which the detection box can be carried. However, the existing handles are usually fixedly installed on the detection box, which is not convenient for storing the handles, and the position of the handles is usually fixed. Therefore, in the process of carrying the detection box by the handle, the hand experience is single, which easily causes the disadvantage of hand fatigue. Therefore, it is necessary to provide a portable water quality heavy metal detector to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of an embodiment of the present invention is to provide a portable water quality heavy metal detector to solve the problems in the above-mentioned background technology.

[0009] The adjusting component is installed in the detection box and connected to the sliding component to drive the sliding component to slide, thereby driving the handle to slide;

[0010] The support assembly is installed on the detection box and is used to support the detection box.

[0011] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0012] The present invention provides a storage component, which is installed on the detection box, and a handle is installed at the end. The storage component is used to drive the handle to slide in the detection box; the adjustment component is installed in the detection box and connected to the storage component, which is used to drive the storage component to slide, and then drive the handle to slide. When the detection box is carried, the detection box can be carried by the handle. When the handle needs to be used, the storage component is rotated, and the storage component can drive the handle to slide outward, so that it is convenient to carry the detection box by the handle. The storage component is rotated in the opposite direction, so that the handle can be stored, and the handle can be protected, and the phenomenon of the handle being exposed to the outside for a long time and being damaged can be prevented. When the position of the handle needs to be adjusted, the adjustment component is rotated, and the adjustment component can drive the storage component to slide through the connection with the storage component, and the position of the handle can be adjusted, so that the feel of the handle can be adjusted during the use of the handle, and the phenomenon of hand fatigue caused by carrying the detection box by the handle for a long time can be prevented.

[0024] A detection box 1, wherein a detector body 11 is installed in the detection box 1;

[0027] The support assembly 6 is installed on the detection box 1 and is used to support the detection box 1 .

[0028] In the embodiment of the present invention, the water quality can be sampled by the sampling component 7. After the water quality is sampled, the detector body 11 can detect the water quality. When the water quality is detected, the reciprocating component 3 is turned on, and the reciprocating component 3 can drive the two groups of mixing components 2 to intermittently and alternately stir the water quality in the detection box 1, effectively improving the uniformity of the water quality in the detection box 1, preventing the precipitation of the water quality from affecting the detection results, and improving the accuracy of the water quality detection. When the detection box 1 is carried, the detection box 1 can be carried by the handle 13. When the handle 13 needs to be used, the sliding component 4 is rotated, and the sliding component 4 can drive the handle 13 to slide outward, so that the detection box 1 is convenient to carry through the handle 13. When the position of the handle 13 needs to be adjusted, the adjusting component 5 is rotated, and the adjusting component 5 can drive the sliding component 4 to slide through the connection with the sliding component 4, so that the position of the handle 13 can be adjusted to different degrees, which is convenient for people with different hand shapes to use the handle 13, and then it is convenient to carry the detection box 1.

[0029] In one embodiment of the present invention, Figure 1 As shown, a mixing assembly 2 is installed inside the detection box 1, and the mixing assembly 2 is used to mix and stir water. The mixing assembly 2 includes:

[0030] A rotating rod 21 is rotatably connected in the detection box 1;

[0031] The stirring blade 22 is connected to the surface of the rotating rod 21 .

[0032] In this embodiment, the rotating rod 21 is rotatably connected in the detection box 1; the stirring blade 22 is connected to the surface of the rotating rod 21. The detection box 1 is provided with a detector body 11. The upper side of the detection box 1 is provided with a carrying strap 14, through which the detection box 1 can be carried, making it easy to carry the detection box 1. The rotating rod 21 and the stirring blade 22 in the mixing assembly 2 are respectively provided with two groups.

[0033] The water quality can be sampled by the sampling assembly 7. After the water quality is sampled, the detector body 11 can detect the water quality. The detector body 11 can adopt the water quality heavy metal detector of Shandong Hengmei Electronic Technology Co., Ltd. to facilitate the detection of water quality.

[0034] The reciprocating component 3 is turned on, and the reciprocating component 3 can drive the rotating rod 21 to reciprocate in the detection box 1. The two groups of rotating rods 21 can drive the stirring blades 22 on the surface thereof to reciprocate when rotating, so that the two groups of stirring blades 22 can mix the water quality in the detection box 1, thereby preventing the precipitation of the water quality from affecting the detection result and improving the accuracy of the water quality detection.

[0035] The mixing assembly 2 may also be replaced by a rotating rod 21 and a spiral blade, wherein the spiral blade is mounted on the surface of the rotating rod 21 so that the spiral blade can rotate under the drive of the rotating rod 21 .

[0036] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, a reciprocating assembly 3 is installed inside the detection box 1, and the reciprocating assembly 3 is connected to the mixing assembly 2 to drive the mixing assembly 2 to slide back and forth intermittently. The reciprocating assembly 3 includes:

[0037] A first gear 31 is mounted on the rotating rod 21;

[0038] A second gear 32 is mounted on another set of rotating rods 21, and the second gear 32 is meshedly connected with the first gear 31;

[0039] A first rotating frame 33, mounted on the rotating rod 21;

[0040] A second rotating frame 34 is mounted on another set of rotating rods 21;

[0041] A driving member 35 is installed in the detection box 1, and an output end of the driving member 35 is connected to a rotating rod 36;

[0042] The rotating frame 37 is installed on the surface of the rotating rod 36, and a rotating column 38 is installed on the side.

[0043] In this embodiment, the first gear 31 is mounted on the rotating rod 21; the second gear 32 is mounted on another set of rotating rods 21, and the second gear 32 and the first gear 31 are meshed and connected; the first rotating frame 33 is mounted on the rotating rod 21; the second rotating frame 34 is mounted on another set of rotating rods 21; the driving member 35 is mounted in the detection box 1, and the output end of the driving member 35 is connected to the rotating rod 36; the rotating frame 37 is mounted on the surface of the rotating rod 36, and a rotating column 38 is mounted on the side.

[0044] When testing the water quality, the driving member 35 is turned on, and the output end of the driving member 35 can drive the rotating rod 36 to rotate. When the rotating rod 36 rotates, the rotating column 38 can be driven to rotate through the rotating frame 37 (such as Figure 3 direction of the arrow).

[0045] When the rotating column 38 contacts the second rotating frame 34, the second rotating frame 34 can drive the rotating rod 21 to rotate on the detection box 1 under the action of the rotating column 38, so that the rotating rod 21 can drive the stirring blades 22 on its surface to rotate, so that the stirring blades 22 can mix and stir the water in the detection box 1. When the rotating rod 21 rotates, it can drive the first gear 31 on its surface to rotate. The first gear 31 can drive the other group of rotating rods 21 to rotate through the meshing connection with the second gear 32, so that the other group of rotating rods 21 can drive the stirring blades 22 on its surface to rotate in the opposite direction, so that the two groups of stirring blades 22 can rotate in the opposite direction, so as to mix the water evenly.

[0046] When the rotating column 38 is separated from the surface of the second rotating frame 34 during rotation, the second rotating frame 34 can stop rotating, so that the stirring blade 22 can stop rotating. When the rotating frame 37 drives the rotating column 38 to contact the first rotating frame 33, the first rotating frame 33 can drive the group of rotating rods 21 to rotate in the opposite direction under the action of the rotating column 38, and then the rotating rod 21 can drive the stirring blade 22 on its surface to rotate in the opposite direction. The two groups of rotating rods 21 can drive the stirring blade 22 on their surface to rotate intermittently and alternately to the water quality in the detection box 1, and then the stirring blade 22 can stir the water quality in the detection box 1 intermittently and alternately, effectively improving the uniformity of the water quality in the detection box 1, preventing the precipitation of the water quality from affecting the detection results, and improving the accuracy of the water quality detection.

[0047] A discharge valve 12 is installed on the side of the detection box 1. After the water quality is tested, the water in the detection box 1 can be discharged through the discharge valve 12.

[0048] The driving member 35 can be an electric motor or a pneumatic motor to drive the rotating rod 36 to rotate stably.

[0049] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the sliding assembly 4 includes:

[0050] The adjusting rod 41 is rotatably connected to the detection box 1, and a rotating cylinder 42 is mounted on the surface;

[0051] The slide groove 43 is provided on the surface of the rotating cylinder 42;

[0052] A guide groove 44 is provided on the inner side of the detection box 1, and a slider 45 is slidably connected therein;

[0053] A fixing frame 46 is mounted on the side of the slider 45 and is slidably connected to a slider 47;

[0054] The sliding column 48 is installed on the side of the sliding member 47 , and the sliding column 48 and the sliding groove 43 are slidably connected.

[0055] In this embodiment, the adjusting rod 41 is rotatably connected to the detection box 1, and a rotating cylinder 42 is installed on the surface; the sliding groove 43 is opened on the surface of the rotating cylinder 42; the guiding groove 44 is opened on the inner side of the detection box 1, and a slider 45 is slidably connected inside; the fixing frame 46 is installed on the side of the slider 45, and a sliding member 47 is slidably connected inside; the sliding column 48 is installed on the side of the sliding member 47, and the sliding column 48 and the sliding groove 43 are slidably connected.

[0056] When the detection box 1 is carried, the detection box 1 can be carried by the handle 13. When the handle 13 is needed, the adjustment rod 41 is rotated, and the adjustment rod 41 can drive the rotating cylinder 42 on its surface to rotate. Since the sliding groove 43 and the sliding column 48 on the surface of the rotating cylinder 42 are slidably connected, the sliding member 47 will drive the fixed frame 46 to slide outward under the action of the sliding groove 43 and the sliding column 48, so that the fixed frame 46 can drive the slider 45 on its side to slide outward in the guide groove 44. The guide groove 44 can limit the fixed frame 46 through the slider 45, thereby improving the stability of the fixed frame 46 when sliding. When the fixed frame 46 slides outward, it can drive the handle 13 on its side to slide outward, so that the detection box 1 can be carried easily by the handle 13.

[0057] Similarly, when the handle 13 is to be stored, the adjusting rod 41 is rotated in the opposite direction, so that the fixing frame 46 can drive the handle 13 at its end to slide inward, so as to facilitate the storage of the handle 13.

[0058] The sliding assembly 4 may also be replaced by an electric telescopic rod, which is installed in the detection box 1 to drive the handle 13 to slide in the detection box 1 .

[0059] In one embodiment of the present invention, Figure 4 As shown, the adjustment component 5 includes:

[0060] A rotating shaft 51 is rotatably connected to the detection box 1, and a gear 52 is mounted on the surface;

[0061] The rack 53 is mounted on the side of the sliding member 47 and is meshedly connected with the gear 52;

[0062] A handle 54 is mounted on the rotating shaft 51;

[0063] The opening 55 is formed on the detection box 1 , and a first magnet 57 is installed inside the opening 55 . The inner wall of the opening 55 is connected to the handle 54 via an elastic member 56 .

[0064] In this embodiment, two groups of the slide grooves 43, the slide column 48 and the slide member 47 are installed respectively, and the bending degrees of the two groups of slide grooves 43 are different. The rotating shaft 51 is rotatably connected to the detection box 1, and a gear 52 is installed on the surface; the rack 53 is installed on the side of the slide member 47 and meshed with the gear 52; the handle 54 is installed on the rotating shaft 51; the opening 55 is opened on the detection box 1, and a first magnet 57 is installed inside, and the inner wall of the opening 55 is connected to the handle 54 through an elastic member 56.

[0065] When the position of the handle 13 needs to be adjusted, the handle 54 is turned leftward, and the handle 54 can drive the rotating shaft 51 to rotate counterclockwise on the detection box 1. When the rotating shaft 51 rotates, it can drive the gear 52 on its surface to rotate. The gear 52 can drive the two sets of sliding members 47 to slide in the opposite direction in the fixed frame 46 through the connection with the two sets of racks 53, so that the sliding member 47 on the left side drives the sliding column 48 on its side to slide into the corresponding sliding groove 43, and the sliding member 47 on the right side drives the sliding column 48 on its side to slide out of the corresponding sliding groove 43, because the bending degrees of the two sets of sliding grooves 43 are different. Therefore, when the adjustment rod 41 is rotated again at this time, the sliding member 47 drives the fixed frame 46 to slide outward to different degrees under the action of the sliding groove 43 and the sliding column 48, and then the fixed frame 46 drives the handle 13 on its side to slide outward to different degrees. Therefore, the position of the handle 13 can be adjusted to different degrees, making it easier for people with different hand shapes to use the handle 13 and further making it easier to carry the detection box 1.

[0066] When the handle 54 is turned rightward and contacts the first magnet 57, the first magnet 57 in the opening 55 can limit and fix the handle 54, and the handle 54 can stretch the elastic member 56. When the handle 54 is turned leftward, the handle 54 can overcome the magnetic force of the first magnet 57 and rotate leftward. At this time, the elastic member 56 can stretch the handle 54 and limit the handle 54, so that the handle 54 can limit the gear 52 through the rotating shaft 51, thereby improving the stability of the two sets of sliding members 47.

[0067] The elastic member 56 can be a spring or elastic rubber to facilitate driving the handle 54 to reset.

[0068] In one embodiment of the present invention, Figure 1 and Figure 6 As shown, the support assembly 6 includes:

[0069] A support frame 61 is hinged on the detection box 1;

[0070] A placement slot 62 is provided on the detection box 1 and a second magnet 63 is installed inside;

[0071] The limiting frame 64 is installed on the detection box 1 and is used to limit the support frame 61 .

[0072] In this embodiment, the support frame 61 is hinged on the detection box 1; the placement slot 62 is opened on the detection box 1, and a second magnet 63 is installed inside; the limiting frame 64 is installed on the detection box 1 to limit the support frame 61.

[0073] When supporting the detection box 1, the support frame 61 is rotated outward so that the side of the support frame 61 contacts the limiting frame 64, and the limiting frame 64 can limit the support frame 61, so that the support frame 61 can support the detection box 1. When storing the support frame 61, the support frame 61 is rotated inward so that the support frame 61 is rotated into the placement groove 62, so that the second magnet 63 can fix the support frame 61, so that the support frame 61 is easy to store.

[0074] The second magnet 63 in the support assembly 6 may also be replaced by a suction cup to facilitate fixing the support frame 61 .

[0075] In one embodiment of the present invention, Figure 1 As shown, a sampling assembly 7 is installed in the detection box 1, and the sampling assembly 7 includes:

[0076] A water pump 71 is installed on the detection box 1;

[0077] The conduit 72 is connected to the output end of the water pump 71 .

[0078] In this embodiment, the water pump 71 is installed on the detection box 1; the conduit 72 is connected to the output end of the water pump 71. When sampling water quality, by placing the end of the conduit 72 into the sampling water source and turning on the water pump 71, the output end of the water pump 71 can pump water into the detection box 1 through the conduit 72, so that the detection box 1 can detect the water quality in the detection box 1.

[0079] The sampling assembly 7 can also be directly replaced by a sampling tube, which is installed on the detection box 1, so that the water quality in the detection box 1 can be sampled through the sampling tube.

[0080] The working principle of the present invention is: the water quality can be sampled through the sampling component 7, and after the water quality sampling is completed, the detector body 11 can detect the water quality.

[0081] When testing the water quality, the driving member 35 is turned on, and the output end of the driving member 35 can drive the rotating rod 36 to rotate. When the rotating rod 36 rotates, it can drive the rotating column 38 to rotate through the rotating frame 37 (as shown in the direction of the arrow in the figure).

[0082] When the rotating column 38 contacts the second rotating frame 34, the second rotating frame 34 can drive the rotating rod 21 to rotate on the detection box 1 under the action of the rotating column 38, so that the rotating rod 21 can drive the stirring blades 22 on its surface to rotate, so that the stirring blades 22 can mix and stir the water in the detection box 1. When the rotating rod 21 rotates, it can drive the first gear 31 on its surface to rotate. The first gear 31 can drive the other group of rotating rods 21 to rotate through the meshing connection with the second gear 32, so that the other group of rotating rods 21 can drive the stirring blades 22 on its surface to rotate in the opposite direction, so that the two groups of stirring blades 22 can rotate in the opposite direction, so as to mix the water evenly.

[0083] When the rotating column 38 is separated from the surface of the second rotating frame 34 during rotation, the second rotating frame 34 can stop rotating, so that the stirring blade 22 can stop rotating. When the rotating frame 37 drives the rotating column 38 to contact the first rotating frame 33, the first rotating frame 33 can drive the group of rotating rods 21 to rotate in the opposite direction under the action of the rotating column 38, and then the rotating rod 21 can drive the stirring blade 22 on its surface to rotate in the opposite direction. The two groups of rotating rods 21 can drive the stirring blade 22 on their surface to rotate intermittently and alternately to the water quality in the detection box 1, and then the stirring blade 22 can stir the water quality in the detection box 1 intermittently and alternately, effectively improving the uniformity of the water quality in the detection box 1, preventing the precipitation of the water quality from affecting the detection results, and improving the accuracy of the water quality detection.

[0084] When the detection box 1 is carried, the detection box 1 can be carried by the handle 13. When the handle 13 is needed, the adjustment rod 41 is rotated, and the adjustment rod 41 can drive the rotating cylinder 42 on its surface to rotate. Since the sliding groove 43 and the sliding column 48 on the surface of the rotating cylinder 42 are slidably connected, the sliding member 47 will drive the fixed frame 46 to slide outward under the action of the sliding groove 43 and the sliding column 48, so that the fixed frame 46 can drive the slider 45 on its side to slide outward in the guide groove 44. The guide groove 44 can limit the fixed frame 46 through the slider 45, thereby improving the stability of the fixed frame 46 when sliding. When the fixed frame 46 slides outward, it can drive the handle 13 on its side to slide outward, so that the detection box 1 can be carried easily by the handle 13.

[0085] Similarly, when the handle 13 is to be stored, the adjusting rod 41 is rotated in the opposite direction, so that the fixing frame 46 can drive the handle 13 at its end to slide inward, so as to facilitate the storage of the handle 13.

[0086] When the position of the handle 13 needs to be adjusted, the handle 54 is turned leftward, and the handle 54 can drive the rotating shaft 51 to rotate counterclockwise on the detection box 1. When the rotating shaft 51 rotates, it can drive the gear 52 on its surface to rotate. The gear 52 can drive the two sets of sliding members 47 to slide in the opposite direction in the fixed frame 46 through the connection with the two sets of racks 53, so that the sliding member 47 on the left side drives the sliding column 48 on its side to slide into the corresponding sliding groove 43, and the sliding member 47 on the right side drives the sliding column 48 on its side to slide out of the corresponding sliding groove 43, because the bending degrees of the two sets of sliding grooves 43 are different. Therefore, when the adjustment rod 41 is rotated again at this time, the sliding member 47 drives the fixed frame 46 to slide outward to different degrees under the action of the sliding groove 43 and the sliding column 48, and then the fixed frame 46 drives the handle 13 on its side to slide outward to different degrees. Therefore, the position of the handle 13 can be adjusted to different degrees, making it easier for people with different hand shapes to use the handle 13 and further making it easier to carry the detection box 1.
