[0040] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The following combination Figure 1-Figure 3 The utility model describes a water turbidity detection device.

[0042] like Figures 1 to 3 As shown, the present invention provides a water turbidity detection device 1, comprising: a liquid storage container 11, a lifting mechanism 12, and a turbidity sensor 13. The liquid storage container 11 is open at the top and is used to hold a water sample to be tested. The lifting mechanism 12 is connected to the liquid storage container 11. The turbidity sensor 13 is configured to extend into the water sample to be tested within the liquid storage container 11 and is connected to the lifting mechanism 12. The lifting mechanism 12 is used to drive the turbidity sensor 13 up and down to adjust the detection height of the turbidity sensor 13.

[0043] In this embodiment, it is understood that the interior of the liquid storage container 11 forms an inner cavity for containing the water sample to be tested, and the top of the inner cavity is open so that the water sample to be tested can be passed into the inner cavity of the liquid storage container 11. The lifting mechanism 12 is provided in the liquid storage container 11. It is understood that the lifting mechanism 12 includes a fixed component and a movable component, the fixed component is installed on the liquid storage container 11, and the movable component is liftably provided on the fixed component. The movable component is connected to the turbidity sensor 13 so that the turbidity sensor 13 can be extended into the water sample to be tested in the liquid storage container 11 so as to detect the turbidity of the water sample to be tested. At the same time, during the detection process, the lifting height of the lifting mechanism 12 can be adjusted according to the detection requirements, and then the depth of the detection end 131 of the turbidity sensor 13 can be adjusted so that the turbidity sensor 13 can detect the turbidity of the water sample to be tested at different depths, which is conducive to a more comprehensive analysis of the water quality of the water sample to be tested.

[0044] The water quality turbidity detection device 1 of the present invention is provided with a liquid storage container 11 with an open top so that a water sample to be tested can be passed into the liquid storage container 11 for detection; a lifting mechanism 12 is provided on the liquid storage container 11, and a turbidity sensor 13 is installed on the lifting mechanism 12. The turbidity sensor 13 can be extended into the water sample to be tested in the liquid storage container 11 to perform turbidity detection; at the same time, the lifting mechanism 12 can be raised and lowered to adjust the height of the turbidity sensor 13, so that the turbidity sensor 13 can detect the turbidity at different depths of the water sample to be tested, thereby better meeting the detection and analysis requirements of the water quality of the water sample to be tested, and effectively solving the defects in the prior art that it is difficult to adjust the depth of the turbidity detection probe and meet the detection requirements.

[0045] It is understandable that the lifting mechanism 12 is usually arranged on the outside or upper end of the side wall of the liquid storage container 11 to avoid contact with the water sample to be tested, so that the water sample to be tested flows into the lifting mechanism 12, affecting the activity and service life of the lifting mechanism 12.

[0046] Specifically, in some embodiments, Figure 1 As shown, the lifting mechanism 12 includes a mounting base 121, a first drive assembly 122, and an adapter frame 123. The mounting base 121 is mounted on the liquid storage container 11. The first drive assembly 122 is mounted on the mounting base 121 and connected to the adapter frame 123. The adapter frame 123 is vertically movable on the mounting base 121. The turbidity sensor 13 is mounted on the adapter frame 123. The first drive assembly 122 is used to drive the adapter frame 123 to move the turbidity sensor 13 up and down.

[0047] In this embodiment, a mounting base 121 is provided on the liquid storage container 11 to support the remaining components of the lifting mechanism 12 and the turbidity sensor 13. Specifically, a first drive assembly 122 is provided on the mounting base 121, and an adapter frame 123 is movably provided on the mounting base 121. The first drive assembly 122 and the adapter frame 123 are in transmission connection to drive the adapter frame 123 to move vertically. The adapter frame 123 is used to mount the turbidity sensor 13, so that the turbidity sensor 13 is located in a suitable position and can be raised and lowered within a suitable height range with the adapter frame 123 to detect the turbidity of the water sample to be tested at different depths in the liquid storage container 11.

[0048] In some embodiments, as Figure 1 As shown, the first drive assembly 122 includes a first drive member 1221, a screw rod 1222, and a threaded sleeve 1223. The first drive member 1221 is disposed on the mounting base 121. The screw rod 1222 extends vertically, and the threaded sleeve 1223 is connected to the adapter frame 123 and threadedly engages with the screw rod 1222. The first drive member 1221 is connected to the screw rod 1222, and the first drive member 1221 is used to drive the screw rod 1222 to rotate, thereby achieving the lifting and lowering of the adapter frame 123 by the threaded sleeve 1223.

[0049] In this embodiment, by connecting the first driving member 1221 and the screw rod 1222, the screw rod 1222 and the threaded sleeve 1223 are threadedly engaged, and the threaded sleeve 1223 is connected to the adapter frame 123. When the first driving member 1221 drives the screw rod 1222 to rotate, the adapter frame 123 is limited by the mounting base 121 and can only move in the vertical direction. The adapter frame 123 can also limit the movement of the threaded sleeve 1223 to only in the vertical direction, so that the threaded sleeve 1223 does not rotate synchronously with the screw rod 1222. Instead, the threaded sleeve 1223 is moved in the vertical direction through the threaded engagement, thereby driving the adapter frame 123 to move in the vertical direction, thereby adjusting the detection height of the turbidity sensor 13. The transmission method of the threaded engagement between the screw rod 1222 and the threaded sleeve 1223 is more stable, and it is also convenient to control the rising or falling height of the threaded sleeve 1223, the adapter frame 123, and the turbidity sensor 13. It has a simple structure and is convenient and practical.

[0050] Specifically, in some embodiments, Figure 1As shown, the mounting base 121 includes a first portion and a second portion. The first portion is mounted above the side wall of the liquid storage container 11, and the second portion extends from the first portion toward the opening of the liquid storage container 11. The first driving member 1221 is mounted on the lower side of the second portion and is located above the opening. The second portion is provided with a limiting hole at the position corresponding to the screw rod 1222. One end of the screw rod 1222 is in transmission connection with the first driving member 1221, and the other end passes through the limiting hole and is threadedly engaged with the threaded sleeve 1223. The adapter frame 123 includes a connecting member and a connecting rod. The threaded sleeve 1223 is connected to the connecting rod through the connecting member. The connecting rod is arranged in a vertical direction. The second portion is provided with a guide hole at the position corresponding to the connecting rod. The connecting rod passes through the guide hole and extends into the inner cavity of the liquid storage container 11. The turbidity sensor 13 is arranged at the lower end of the connecting rod.

[0051] Specifically, based on the above embodiment, a scale ruler can be set on the connecting rod along the height direction, and the inspection personnel can judge the current height of the turbidity sensor 13 according to the scale corresponding to the edge of the current guide hole on the scale ruler, so as to control the lifting mechanism 12 to lift and lower, and adjust the turbidity sensor 13 to the depth position where turbidity detection is required.

[0052] In some embodiments, as Figure 1 As shown, the water turbidity detection device 1 further includes a display 14 , which is communicatively connected to the turbidity sensor 13 , and is used to display the detection result of the turbidity sensor 13 .

[0053] In this embodiment, a display 14 communicatively connected to the turbidity sensor 13 is provided to receive and display the detection data of the turbidity sensor 13 , so as to facilitate the detection personnel to observe and record the turbidity of the water sample to be detected during the detection process.

[0054] It is understandable that the display 14 can be directly mounted on the mounting base 121 of the above embodiment.

[0055] In some embodiments, as Figure 1 As shown, the water turbidity detection device 1 further includes a first cleaning assembly 15, which includes a second drive assembly 151, a telescopic rod 152, and a cleaning brush 153. The second drive assembly 151 is mounted on the mounting base 121. The telescopic rod 152 is vertically retractable and connected to the second drive assembly 151. The cleaning brush 153 is mounted at the lower end of the telescopic rod 152. The second drive assembly 151 is configured to rotate the telescopic rod 152, thereby driving the cleaning brush 153 to clean the lower end of the turbidity sensor 13.

[0056] In this embodiment, a second drive assembly 151 is provided on the mounting base 121, and the second drive assembly 151 is transmission-connected to the telescopic rod 152. The telescopic rod 152 is provided in a vertical direction so as to extend to a height position lower than the turbidity sensor 13, so that the cleaning brush 153 at the lower end of the telescopic rod 152 can be located in the same plane as the lower end of the turbidity sensor 13. The second drive assembly 151 can drive the telescopic rod 152 to rotate, thereby driving the cleaning brush 153 to rotate, so that the cleaning brush 153 can wipe the lower end of the turbidity sensor 13 and clean the dirt attached to the lower end of the turbidity sensor 13.

[0057] It is understandable that the detection end 131 of the turbidity sensor is located at the lower end, and the cleaning brush 153 can rotate to clean the detection end 131 of the turbidity sensor 13 to prevent dirt from adhering to the detection end 131 and affecting the detection accuracy of the turbidity sensor 13.

[0058] At the same time, the telescopic rod 152 can be extended and retracted in the vertical direction so as to adjust the height of the cleaning brush 153 according to the height of the turbidity sensor 13 to ensure that the lower end of the turbidity sensor 13 can be wiped and cleaned when the turbidity sensor 13 is located at different heights.

[0059] Specifically, in some embodiments, Figure 1 As shown, the telescopic rod 152 includes a first rod 1521 and a second rod 1522. The second rod 1522 is slidably mounted on the first rod 1521 in a vertical direction. The first rod 1521 is connected to the second drive assembly 151. The second rod 1522 is connected to the adapter frame 123. The cleaning brush 153 is mounted on the lower end of the second rod 1522.

[0060] In this embodiment, the first rod 1521 is connected to the second driving assembly 151 so that it can rotate under the drive of the second driving assembly 151 and drive the second rod 1522 and the cleaning brush 153 to rotate; the second rod 1522 is connected to the adapter frame 123, and the cleaning brush 153 is arranged on the second rod 1522. When the first driving assembly 122 drives the adapter frame 123 to rise and fall to adjust the height of the turbidity sensor 13, the adapter frame 123 will also drive the second rod 1522 to rise and fall, so that the cleaning brush 153 and the turbidity sensor 13 are synchronously raised and lowered, so that the brushing surface of the cleaning brush 153 and the lower end surface of the turbidity sensor 13 are always maintained at the same height, so that the cleaning brush 153 can contact the lower end surface of the turbidity sensor 13 when rotating, and wipe and clean the lower end of the turbidity sensor 13. The structure is simple and there is no need to manually adjust the telescopic rod 152.

[0061] Specifically, in some embodiments, Figure 1 and Figure 2As shown, the second drive assembly 151 includes a second drive member 1511, a gear 1512, and a rack 1513. The second drive member 1511 is disposed on the mounting base 121 and is in driving connection with the rack 1513. The gear 1512 is sleeved on the telescopic rod 152 and meshes with the rack 1513. The second drive member 1511 is used to drive the rack 1513 to move, thereby driving the gear 1512 to rotate.

[0062] In this embodiment, the second driving member 1511 and the rack 1513 are connected in a transmission manner to drive the rack 1513 to move in the horizontal direction. The rack 1513 is engaged with the gear 1512. When the rack 1513 moves horizontally, it drives the gear 1512 to rotate, thereby driving the telescopic rod 152 to rotate, so that the cleaning brush 153 at the lower end of the telescopic rod 152 can rotate to wipe and clean the lower end of the turbidity sensor 13. The structure is simple, convenient and practical.

[0063] Specifically, in some embodiments, Figure 3 As shown, the cleaning brush 153 is annular in shape, with the telescopic rod 152 and the outer peripheral wall of the cleaning brush 153 connected. The cleaning brush 153 is provided with an opening for avoiding the detection end 131 of the turbidity sensor 13. During cleaning, the second driving member 1511 can drive the rack 1513 to reciprocate horizontally, thereby driving the telescopic rod 152 and the cleaning brush 153 to reciprocate to wipe the detection end 131 of the turbidity sensor 13. When cleaning is not required, the cleaning brush 153 is parked directly below the turbidity sensor 13, and the detection end 131 of the turbidity sensor 13 can be exposed through the opening to facilitate water quality testing.

[0064] In some embodiments, as Figure 1 As shown, the water turbidity detection device 1 further includes a second cleaning assembly 16. The second cleaning assembly 16 includes a third driving member 161 and a cleaning member 162. The third driving member 161 and the cleaning member 162 are drivingly connected, and the cleaning member 162 contacts the inner wall of the liquid storage container 11. The third driving member 161 is used to drive the cleaning member 162 to move along the inner wall of the liquid storage container 11.

[0065] In this embodiment, the third driving member 161 can drive the cleaning member 162 to move along the inner wall of the liquid storage container 11, so that the cleaning member 162 can wipe and clean the inner wall of the liquid storage container 11, remove dirt attached to the inner wall, and keep the inner wall of the liquid storage container 11 clean.

[0066] It is understandable that the third driving member 161 can be a robotic arm, which can flexibly drive the cleaning member 162 to move on the inner wall of the liquid storage container 11 to wipe the inner wall; the third driving member 161 can also be a motor and a transmission mechanism, and the motor is connected to the cleaning member 162 through the transmission mechanism, so that the cleaning member 162 moves along a fixed motion trajectory on the inner wall of the liquid storage container 11 to wipe the inner wall.

[0067] In some specific embodiments, Figure 1 As shown, the liquid storage container 11 has a cylindrical inner cavity. The third driving member 161 includes a rotary motor. The output shaft of the rotary motor is arranged along the central axis of the liquid storage container 11. The cleaning member 162 contacts the inner wall of the liquid storage container 11.

[0068] In this embodiment, by setting the inner cavity of the liquid storage container 11 to a cylindrical shape and setting the output shaft of the rotating motor at the central axis position of the liquid storage container 11, the rotating motor drives the cleaning member 162 to rotate around the central axis of the liquid storage container 11 through the output shaft, so that the cleaning member 162 can complete the wiping and cleaning of the inner wall of the liquid storage container 11 in the circumferential direction. The transmission structure is simple, convenient and practical.

[0069] Optionally, by reasonably arranging the structure of the cleaning member 162, the cleaning member 162 can also be brought into contact with the bottom wall of the liquid storage container 11, so that the cleaning member 162 can complete wiping and cleaning of the inner bottom wall of the liquid storage container 11 along the circumferential direction; or, the cleaning member 162 can be brought into contact with both the inner side wall and the bottom wall of the liquid storage container 11, so that the cleaning member 162 can clean the inner side wall and the bottom wall at the same time during the rotation process.

[0070] Specifically, in some embodiments, Figure 1 As shown, the cleaning member 162 includes a first brush body 1621, a second brush body 1622 and a third brush body 1623; the first brush body 1621 is transmission-connected to the rotating motor and extends radially along the inner cavity of the liquid storage container 11, and the first brush body 1621 contacts the bottom wall of the liquid storage container 11; the second brush body 1622 and the third brush body 1623 are respectively arranged at both ends of the first brush body 1621, and the second brush body 1622 and the third brush body 1623 are both extended from the first brush body 1621 along the axial direction of the inner cavity of the liquid storage container 11, and the second brush body 1622 and the third brush body 1623 respectively contact the inner side walls on opposite sides of the liquid storage container 11.

[0071] In this embodiment, a first brush body 1621 is drivingly connected to a rotating motor and contacts the bottom wall of the liquid storage container 11. The rotating motor drives the first brush body 1621 to rotate, thereby wiping and cleaning the entire bottom wall of the liquid storage container 11. A second brush body 1622 and a third brush body 1623 are respectively disposed at each end of the first brush body 1621. Both the second brush body 1622 and the third brush body 1623 contact the inner sidewall of the liquid storage container 11. Rotation of the first brush body 1621 drives the second and third brush bodies 1622, 1623 to rotate circumferentially along the liquid storage container 11, thereby cleaning the inner sidewall of the liquid storage container 11. Simultaneously, the second and third brush bodies 1622, 1623 contact opposite inner sidewalls of the liquid storage container 11. This ensures that the cleaning element 162 is supported by the inner sidewalls of the liquid storage container 11 during rotation of the first brush body 1621, resulting in more balanced force and more stable rotation.

[0072] Furthermore, the second brush body 1622 and the third brush body 1623 have the same structure and are axially symmetrically arranged relative to the central axis of the liquid storage container 11, so that the center of gravity of the cleaning member 162 can fall on the central axis of the liquid storage container 11, and the rotation is more stable.

[0073] In some embodiments, as Figure 1 As shown, the liquid storage container 11 is further provided with a drain hole connected to the inner cavity, and a valve is provided in the drain hole. The drain hole of this embodiment is used to discharge the water sample to be tested after the test is completed, and the valve is used to control the opening and closing of the drain hole.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
