Description

[0002] At present, with the continuous improvement of the country's environmental protection requirements, the water treatment industry has developed rapidly. At present, the pretreatment stage of water treatment is mainly based on coagulation, clarification, and filtration technologies. Therefore, the equipment in the pretreatment stage is often relatively large. In daily operation, it is necessary to sample and analyze in various large water pools such as clarification pools and filtration pools. However, most of the sampling is still based on hanging bottle sampling, that is, a heavy bottle is tied with a rope and dropped into the water for sampling. However, this sampling method has many limitations and can only be sampled at the edge of the pool. The water sample flow rate is slow, and the water quality is quite different from that in the center of the pool, or the water quality at the bottom of the pool and the upper layer is also quite different.

[0037] It should be noted that when it is necessary to quickly realize the first monitoring unit 201 and the second monitoring unit 202 to monitor the water sample, the third driving component 205c is driven by the cooperation of the first driving component 205a and the second driving component 205b. Furthermore, the third driving component 205c can simultaneously drive the first monitoring unit 201 and the second monitoring unit 202 to monitor the water sample.

[0038] Preferably, the device can not only realize the driving and monitoring function of any monitoring unit through the driving unit 205, but also realize the rapid driving and monitoring function of two monitoring units at the same time.

[0039] Furthermore, the first driving assembly 205a includes a first driving member 205a-1 movably disposed in the installation box 203, and a first driven member 205a-2 driven by the first driving member 205a-1;

[0042] The first follower member 205a-2 includes a first follower rod 205a-21 driven by the first driving rod 205a-11, a first connecting rod 205a-22 one end of which is fixedly connected to the side wall of the first follower rod 205a-21, a first cover 205a-23 fixedly connected to the other end of the first connecting rod 205a-22, and a second spring 205a-24 connecting the first follower rod 205a-21 and the inner wall of the mounting box 203, wherein the contact surfaces of the first follower rod 205a-21 and the first driving rod 205a-11 are both inclined surfaces, the first cover 205a-23 moves along the outer surface of the sampling tube 103, and the first follower rod 205a-21 is limited by the third driving assembly 205c.

[0043] It should be noted that in the initial state, the first cover 205a-23 covers the first opening 103a. When an external force drives the first driving rod 205a-11 to move linearly along the mounting box 203 (the first spring 205a-14 is compressed), the first follower rod 205a-21, under the drive of the first driving rod 205a-11 and the limiting cooperation of the third driving component 205c, drives the first cover 205a-23 to move horizontally along the outer surface of the sampling tube 103 (the second spring 205a-24 is compressed). At this time, the mounting box 203 is connected to the sampling tube 103.

[0044] Further, the second driving member 205b-1 includes a second driving rod 205b-11 with one end movably inserted into the installation box 203, a second L-shaped rod 205b-12 with one end fixedly connected to the side wall of the second driving rod 205b-11, a second oblique rod 205b-13 fixedly connected to the side wall of the second L-shaped rod 205b-12, and a third spring 205b-14 with one end fixedly connected to the second L-shaped rod 205b-12, wherein the other end of the third spring 205b-14 contacts with the limit assembly 205d;

[0045] The second follower member 205b-2 includes a second follower rod 205b-21 driven by the second driving rod 205b-11, a second connecting rod 205b-22 one end of which is fixedly connected to the side wall of the second follower rod 205b-21, a second cover 205b-23 fixedly connected to the other end of the second connecting rod 205b-22, and a fourth spring 205b-24 connecting the second follower rod 205b-21 and the inner wall of the mounting box 203, wherein the contact surfaces of the second follower rod 205b-21 and the second driving rod 205b-11 are both inclined surfaces, the second cover 205b-23 moves along the outer surface of the sampling tube 103, and the first follower rod 205a-21 is limited by the third driving assembly 205c.

[0046] It should be noted that in the initial state, the second cover 205b-23 covers the second opening 103b. When external force drives the second driving rod 205b-11 to move linearly along the installation box 203 (the third spring 205b-14 is compressed), the second follower rod 205b-21, under the drive of the second driving rod 205b-11 and the limiting cooperation of the third driving component 205c, drives the second cover 205b-23 to move horizontally along the outer surface of the sampling tube 103 (the fourth spring 205b-24 is compressed). At this time, the installation box 203 is connected to the sampling tube 103.

[0047] Furthermore, the third driving assembly 205c includes a first turntable 205c-1 rotatably connected to the installation box 203, a first connecting plate 205c-2 fixedly connected to the side wall of the first turntable 205c-1, a second connecting plate 205c-3 and a rotating shaft 205c-4, a fifth spring 205c-5 fixedly connected to the first connecting plate 205c-2 at one end, a sixth spring 205c-6 fixedly connected to the second connecting plate 205c-3 at one end, a first arc-shaped limit plate 205c-7 fixedly connected to the side wall of the first driving rod 205a-11, and first magnets fixedly arranged at both ends of the first arc-shaped limit plate 205c-7. 205c-8, a second arc-shaped limit plate 205c-9 fixedly connected to the side wall of the second driving rod 205b-11, a second magnet 205c-10 fixedly arranged at both ends of the second arc-shaped limit plate 205c-9, and a third follower 205c-11 driven by the rotating shaft 205c-4, wherein the first connecting plate 205c-2 and the second connecting plate 205c-3 are symmetrically arranged around the center of the first turntable 205c-1, the other end of the fifth spring 205c-5 contacts the side wall of the first driving rod 205a-11, and the other end of the sixth spring 205c-6 contacts the side wall of the second driving rod 205b-11.

[0048] It should be noted that when external force drives the first driving rod 205a-11 and the second driving rod 205b-11 to move horizontally close to each other, the first arc-shaped limit plate 205c-7 and the second arc-shaped limit plate 205c-9 synchronously move horizontally close to each other. Through the magnetic attraction of the first magnet 205c-8 and the second magnet 205c-10, the first turntable 205c-1 is wrapped by the first arc-shaped limit plate 205c-7 and the second arc-shaped limit plate 205c-9. When the first driving rod 205a-11 and the second driving rod 205b-11 are driven to move along the special-shaped opening, the first turntable 205c-1 is driven to rotate. The rotation of the first turntable 205c-1 synchronously drives the rotating shaft 205c-4 to rotate, and further drives the third follower 205c-1 to move.

[0049] Furthermore, the third follower 205c-11 includes a second turntable 205c-11a fixedly connected to the rotating shaft 205c-4, two arc-shaped openings 205c-11b arranged on the second turntable 205c-11a, a mounting seat 205c-11c fixedly connected to the interior of the mounting box 203, a movable column 205c-11d moving along the arc-shaped opening 205c-11b, and a movable plate 205c-11e fixedly connected to one end of the movable column 205c-11d, wherein two movable columns 205c-11d and two movable plates 205c-11e are provided, and the two movable plates 205c-11e can only move in a straight line under the limiting cooperation of the two movable columns 205c-11d and the mounting seat 205c-11c.

[0050] It should be noted that the rotating shaft 205c-4 rotates, synchronously driving the second turntable 205c-11a to rotate, and the movable column 205c-11d moves along the arc-shaped opening 205c-11b, thereby driving the two movable plates 205c-11e to move linearly. The two movable plates 205c-11e move linearly and simultaneously push the first follower rod 205a-21 and the second follower rod 205b-21 to move horizontally, thereby removing the blocking effect of the first cover 205a-23 and the second cover 205b-23 on the first opening 103a and the second opening 103b.

[0051] Furthermore, the limiting assembly 205d includes a fixing plate 205d-1 fixedly connected to the inner wall of the installation box 203, a seventh spring 205d-2 fixedly connected to the inner wall of the installation box 203 at one end, and a seventh spring 205d-3 fixedly connected to the inner wall of the installation box 203 at one end.

[0052] A slotted plate 205d-3 to which the other end of 205d-2 is fixedly connected, a reset rod 205d-4 movably arranged in the installation box 203, a third inclined rod 205d-5 one end of which is fixedly connected to the side wall of the reset rod 205d-4, and an eighth spring 205d-6 one end of which is fixedly connected to the reset rod 205d-4, wherein the other ends of the first spring 205a-14 and the third spring 205b-14 are both in contact with the fixed plate 205d-1, and a slot is provided on the fixed plate 205d-1, so that the first driving rod 205a-11 and the second driving rod 205b-11 can move freely without being restricted by the fixed plate 205d-1, and a slot is provided on the slotted plate 205d-3 opposite to the first inclined rod 205a-13, the second inclined rod 205b-13 and the third inclined rod 205d-5.

[0053] It should be noted that when the first driving rod 205a-11 or the second driving rod 205b-11 moves linearly along the installation box 203, the first inclined rod 205a-13 or the second inclined rod 205b-13 squeezes the slot to drive the slotted plate 205d-3 to move horizontally (the seventh spring 205d-2 is compressed), and further the first inclined rod 205a-13 or the second inclined rod 205b-13 engages with the slotted plate 205d-3 to fix it, and the fixing effect can be released by unlocking the reset rod 205d-4 or another driving rod.

[0054] Preferably, when only a single monitoring is to be implemented, the corresponding driving rod can be directly driven to drive and implement the monitoring. Furthermore, when another driving rod is driven, the current driving rod can be automatically reset and the function of switching monitoring can be realized.

[0055] Further, the first monitoring unit 201 includes a first inclined block 201a fixedly connected to the first connecting rod 205a-22, a ninth spring 201b having one end fixedly connected to the installation box 203, a first lifting rod 201c fixedly connected to the other end of the ninth spring 201b, and a PH electrode 201d connected to one end of the first lifting rod 201c, wherein the contact surfaces of the first inclined block 201a and the first lifting rod 201c are both inclined surfaces;

[0056] It should be noted that when the first connecting rod 205a-22 moves linearly, it synchronously drives the first inclined block 201a to move linearly. The first inclined block 201a drives the first lifting rod 201c to move linearly through the inclined surface, drives the PH electrode 201d to rise and fall, and the PH motor passes through the first opening 103a to realize the monitoring of the water body.

[0057] The second monitoring unit 202 includes a second inclined block 202a fixedly connected to the second connecting rod 205b-22, a tenth spring 202b fixedly connected to the installation box 203 at one end, a second lifting rod 202c fixedly connected to the other end of the tenth spring 202b, and a conductivity electrode 202d connected to one end of the second lifting rod 202c, wherein the contact surfaces of the second inclined block 202a and the second lifting rod 202c are both inclined surfaces.

[0058] It should be noted that when the second connecting rod 205b-22 moves linearly, it synchronously drives the second inclined block 202a to move linearly. The second inclined block 202a drives the second lifting rod 202c to move linearly through the inclined surface, driving the conductivity electrode 202d to move up and down. The conductivity electrode 202d passes through the second opening 103b to monitor the water body.

[0059] Furthermore, the telescopic unit 101 includes a telescopic protective tube 101 a having one end connected to the input end of the self-priming diaphragm pump 102 , and a telescopic tube 101 b disposed in the telescopic protective tube 101 a .

[0060] It should be noted that by adjusting the extension and retraction of the telescopic protective tube 101a and driving the extension and retraction of the telescopic tube 101b at the same time, sampling of water bodies at any position can be achieved, which can effectively improve the representativeness of sampling.

[0061] When in use, the present invention includes two use states:

[0062] The first usage state is monitored by a single monitoring unit. This usage state includes two usage processes.

[0063] In the first use process, only the monitoring function of the first monitoring unit 201 or the second monitoring unit 202 is performed. Specifically, by adjusting the telescopic unit 101, the collection end of the telescopic tube 101b is moved to the place to be collected, and the self-priming diaphragm pump 102 is started. The water flows through the telescopic tube 101b through the sampling tube 103 into the sampling bottle. When the water flows through the sampling tube 103, according to the monitoring requirements, any driving rod is driven to move linearly along the installation box 203. The current driving rod moves synchronously and drives the corresponding inclined rod and the corresponding driven rod to move linearly. The current driven rod drives the corresponding connecting rod, and drives the corresponding cover to move linearly along the surface of the sampling tube 103 through the connecting rod. At the same time, the connecting rod moves through the inclined block to make the corresponding lifting rod move linearly, and further drives the corresponding electrode to pass through the corresponding opening to realize the monitoring function. On the other hand, the corresponding inclined rod is engaged with the slotted plate 205d-3. By driving the reset rod 205d-4 or another driving rod to drive the slotted plate 205d-3 to move, the limiting effect on the current driving rod can be released.

[0064] In the second usage process, the two monitoring units need to be monitored one by one. Specifically, when the water flows through the sampling tube 103, according to the monitoring requirements, any driving rod is driven to move linearly along the installation box 203. The current driving rod movement synchronously drives the corresponding inclined rod and the corresponding driven rod to move linearly. The current driven rod drives the corresponding connecting rod, and the corresponding cover is driven by the connecting rod to move linearly along the surface of the sampling tube 103. At the same time, the connecting rod moves through the inclined block to make the corresponding lifting rod move linearly, and further drives the corresponding electrode to pass through the corresponding opening to realize the monitoring function. On the other hand, the corresponding inclined rod is engaged with the slotted plate 205d-3. Further, by driving another driving rod to drive the slotted plate 205d-3 to move, the limiting effect on the previous driving rod can be released while realizing the limiting effect on the current driving rod, thereby realizing the switching of the monitoring function of another monitoring unit. Finally, the reset rod 205d-4 can be driven to reset the device.

[0065] In the second usage state, the two monitoring units monitor at the same time. Specifically, when the water flows through the sampling tube 103, the external force simultaneously drives the first driving rod 205a-11 and the second driving rod 205b-11 to move horizontally close to each other, and the first arc-shaped limit plate 205c-7 and the second arc-shaped limit plate 205c-9 synchronously move horizontally close to each other. Under the magnetic attraction of the first magnet 205c-8 and the second magnet 205c-10, the first turntable 205c-1 is wrapped by the first arc-shaped limit plate 205c-7 and the second arc-shaped limit plate 205c-9. When the first driving rod 205a-11 and the second driving rod 205b-11 are driven to move along the special-shaped opening, the first turntable 205c-1 is driven to rotate. The rotation of the first turntable 205c-1 synchronously drives the rotating shaft 205c-4 to rotate, and the rotating shaft 205 c-4 rotates, synchronously driving the second turntable 205c-11a to rotate, and the movable column 205c-11d moves along the arc-shaped opening 205c-11b, thereby driving the two movable plates 205c-11e to move linearly. The two movable plates 205c-11e move linearly and simultaneously push the first driven rod 205a-21 and the second driven rod 205b-21 to move horizontally, thereby releasing the blocking effect of the first cover 205a-23 and the second cover 205b-23 on the first opening 103a and the second opening 103b. On the other hand, the first lifting rod 201c and the second lifting rod 202c are driven to move linearly through the first inclined block 201a and the second inclined block 202a, so that the pH electrode 201d and the conductivity electrode 202d can respectively pass through the first opening 103a and the second opening 103b to monitor the water body.

[0066] In summary, the beneficial effect of the portable water sampling device with online monitoring of the present invention is that through the setting of the telescopic unit 101, sampling of water in any part can be achieved, which can effectively improve the representativeness of the sampling. Through the setting of the driving unit 205, not only can any monitoring unit be selected for monitoring according to actual monitoring needs, but also the rapid driving and monitoring of two monitoring units can be achieved at the same time, further improving the practicality of the device.
