[0041] like Figure 1-Figure 13 As shown, an alkali solution concentration detection device of the present invention comprises an intermediate frame 1, a rotating seat 2 is rotatably connected to the intermediate frame 1, and a placement seat 3 is fixedly connected to the four sides of the top of the rotating seat 2;

[0042] A lifting assembly 4 is arranged in the middle frame 1, and the lifting assembly 4 includes a double-headed motor 41 fixed on one side of the middle frame 1 and used as a unified driving source, and a detection assembly 5 and a cleaning assembly 6 are arranged around the outer side of the lifting assembly 4. The concentration and pH value of the alkali solution are differentiated and measured by alternating lifting, thereby improving the comprehensiveness and accuracy of the alkali solution measurement results, and at the same time, the container can also be cleaned after the measurement is completed.

[0043] like Figure 6-Figure 10 As shown, an output shaft of the double-headed motor 41 is embedded with a first electric push rod 42, and the piston rod of the first electric push rod 42 is fixedly connected to the first driving bevel gear 43, and the bottom of the inner cavity of the intermediate frame 1 is rotatably connected to the driven bevel gear 44 used in conjunction with the first driving bevel gear 43. The double-headed motor 41 first provides a unified driving source to save power costs, and the first electric push rod 42 adjusts the meshing stroke between the first driving bevel gear 43 and the driven bevel gear 44, and the top of the driven bevel gear 44 is fixedly connected to a rotating shaft 45, and the top of the rotating shaft 45 is fixedly connected to a threaded rod 46, and the threaded rod 46 is threadedly connected to a threaded barrel 47 that slides with the intermediate frame 1, and then the threaded rod 46 on the rotating shaft 45 realizes the lifting and lowering adjustment effect of the threaded barrel 47 according to actual needs, which provides convenience for the subsequent determination of alkali solution and replaces manual intervention.

[0044] The detection assembly 5 includes a short curved arm 51 fixed around the top of the threaded barrel 47, and the first electric telescopic rod 52 and the second electric telescopic rod 54 are fixedly connected to the side of the short curved arm 51 away from the threaded barrel 47, and the piston rods of the first electric telescopic rod 52 and the second electric telescopic rod 54 are fixedly connected to the concentration meter 53 and the pH meter 55, respectively. The first electric telescopic rod 52 and the second electric telescopic rod 54 on the three short curved arms 51 drive the concentration meter 53 and the pH meter 55 to rise and fall synchronously after being adjusted to the right position, and then the three groups of the first electric telescopic rods 52 and the second electric telescopic rods 54 are used to move the concentration meter 53 and the pH meter 55 to the right position. The electric telescopic rod 54 is corresponding to inserting the concentration meter 53 and the pH meter 55 into the alkali solution to measure the concentration and pH value respectively, and a small electric heater 56 is fixedly connected to the outside of the placement seat 3, and an electric heating coil 57 used in conjunction with the small electric heater 56 is embedded at the bottom of the inner cavity of the placement seat 3. At the same time, three groups of small electric heaters 56 and electric heating coils 57 provide heating conditions for the alkali solution according to actual requirements, and the concentration and pH value of the alkali solution can be compared and measured under normal temperature and high temperature conditions, making the measurement of the alkali solution more comprehensive and accurate;

[0045] The middle frame 1 is vertically provided with limit slide grooves 8 around it, and the inner cavity of the limit slide groove 8 is slidably connected with a limit slide 9 fixedly matched with the threaded cylinder 47, which plays a role of sliding limit on the lifting stroke of the threaded cylinder 47 and improves the lifting stability of the threaded cylinder 47. The top of the threaded cylinder 47 is fixedly connected with an alarm light, and the front of the rotating seat 2 is provided with a PLC controller used in conjunction with the alarm light to control the power supply components and also provide light warning for the operating status;

[0046] The first electric telescopic rod 52 and the concentration meter 53 on the short curved arm 51 are distributed in a triangular equidistant state along the central axis of the threaded barrel 47 with the second electric telescopic rod 54 and the pH meter 55, so that the first electric telescopic rod 52 and the concentration meter 53 and the second electric telescopic rod 54 and the pH meter 55 are reasonably distributed along the threaded barrel 47, and the concentration and pH value of the alkali solution are comprehensively measured. The sealing cover 62, the small motor 63 and the cleaning brush 64 on the long curved arm 61 are distributed in a triangular equidistant state along the central axis of the threaded barrel 47 and are staggered with the short curved arm 51, thereby improving the rationality of the distribution between the short curved arm 51 and the long curved arm 61 to prevent the concentration meter 53 and the pH meter 55 from colliding and interfering with the cleaning brush 64.

[0047] The cleaning assembly 6 includes a long curved arm 61 fixed on the other four sides of the top of the threaded cylinder 47, and a plugging cover 62 is fixedly connected to the side of the long curved arm 61 away from the threaded cylinder 47, a small motor 63 is fixedly connected to the center of the top of the plugging cover 62, and a cleaning brush 64 is fixedly connected to the output shaft of the small motor 63. The plugging covers 62 on the three long curved arms 61 first drive the cleaning brush 64 on the small motor 63 to reach the three groups of alkali solution after pouring, and clean the alkali solution remaining in the three groups of alkali solution. The subsequent cleaning operation of the three groups of alkali solution in the filling cups 12 is replaced by manual cleaning to avoid hurting the hands. A small water bucket 65 is fixedly connected to the side of the long curved arm 61 close to the small motor 63, and the bottom end of the small water bucket 65 is connected to a three-way joint 66, and both ends of the three-way joint 66 are connected to a water supply pipe 67 connected and matched with the plugging cover 62. At the same time, the three groups of small water buckets 65, the three-way joint 66 and the water supply pipe 67 provide detergent supply to the filling cup 12;

[0048] A sealing groove 10 is provided in a ring shape at the bottom of the sealing cover 62, and water supply ports 11 connected to the water supply pipe 67 are provided on both sides of the inner cavity of the sealing cover 62. A containing cup 12 used in conjunction with the concentration meter 53, the pH meter 55, the electric heating ring 57, the sealing cover 62, the cleaning brush 64 and the sealing groove 10 is placed in the inner cavity of the placement seat 3, thereby improving the sealing performance between the sealing cover 62 and the containing cup 12, and facilitating the injection of detergent into the empty containing cup 12, thereby facilitating the cleaning of the containing cup 12, and also heating the containing cup 12 containing the alkali solution.

[0049] like Figure 11-13As shown, after the alkali solution is measured and the alkali solution in the three groups of containing cups 12 is poured out, the three groups of containing cups 12 are mostly cleaned manually. Since the walls of the three groups of containing cups 12 are attached with residual alkali solution, it is easy to hurt the hands. According to actual needs, it is not possible to adopt a flexible transposition method to transfer the three groups of containing cups 12 to directly below the three groups of cleaning brushes 64 to achieve automatic cleaning effect. A transposition component 7 is provided in the rotating seat 2, and the transposition component 7 includes a second electric push rod 71 embedded in another output shaft of the double-headed motor 41, and the piston rod of the second electric push rod 71 is fixedly connected to the second driving bevel gear 72, and the bottom of the rotating seat 2 is fixedly connected to a convex gear ring 73 used in conjunction with the second driving bevel gear 72, and the second electric push rod 71 is used to adjust the meshing stroke between the second driving bevel gear 72 and the convex gear ring 73;

[0050] An annular slide rail 74 is provided on the top of the intermediate frame 1, and the inner cavity of the annular slide rail 74 is slidably connected with a supporting slide seat 75 fixedly matched with the rotating seat 2. The intermediate frame 1 is fixedly connected with a limiting cylinder 76 near the convex gear ring 73, and the limiting cylinder 76 is provided with a limiting slide 77 slidably matched with the convex gear ring 73. When the double-headed motor 41 drives the three groups of serving cups 12 on the rotating seat 2 to rotate and transpose through the engaged second drive bevel gear 72 and the convex gear ring 73, the annular slide rail 74 and the supporting slide seat 75 play a role of sliding support for the rotating seat 2, and at the same time, the limiting slide 77 on the three groups of limiting cylinders 76 play a role of limiting and preventing the convex gear ring 73 from falling off, thereby improving the stability of the three groups of serving cups 12 during the rotation and transposition.

[0051] The working principle of an alkali solution concentration detection device is as follows: first, the alkali solution to be measured is injected into three groups of containing cups 12, and the three groups of containing cups 12 containing the predetermined amount of alkali solution are placed in three groups of placing seats 3 on the rotating seat 2, and the three groups of containing cups 12 are located directly below the three groups of concentration meters 53 and the pH meter 55, firstly, the first electric push rod 42 is controlled to start and drive the first driving bevel gear 43 to move forward to the meshing part of the driven bevel gear 44, and then the double-headed motor 41 is controlled to start and drive the first driving bevel gear 43 to move forward to the meshing part of the driven bevel gear 44 through the meshing of the first driving bevel gear 43. The wheel 43 drives the driven bevel gear 44 to rotate, and the driven bevel gear 44 drives the threaded rod 46 to rotate forward through the rotating shaft 45. The limited slide groove 8 and the limited slide 9 play a sliding limit role on the threaded cylinder 47. Then, the threaded rod 46 drives the threaded cylinder 47 at the initial high position to move down to a predetermined height from the three groups of filling cups 12, and then the double-headed motor 41 is controlled to pause, and then the first electric push rod 42 is controlled to close and drive the first driving bevel gear 43 to move backward to disengage from the meshing part of the driven bevel gear 44 to the initial position;

[0052] After the threaded cylinder 47 drives the first electric telescopic rod 52 and the second electric telescopic rod 54 on the three short curved arms 51 to synchronously move downward to a predetermined height from the three groups of filling cups 12, according to the measurement sequence, the three groups of first electric telescopic rods 52 are first controlled to open and drive the three groups of concentration meters 53 to be inserted downward into the alkali solution contained in the three groups of filling cups 12. Under normal temperature conditions, after the concentration of the current three portions of alkali solution is measured, the three groups of first electric telescopic rods 52 are closed and drive the three groups of concentration meters 53 to move upward and reset. Similarly, the three groups of second electric telescopic rods 54 are opened and drive the three groups of pH meters 55 to be inserted downward into the alkali solution contained in the three groups of filling cups 12. Under normal temperature conditions, after the pH value of the current three portions of alkali solution is measured, the three groups of second electric telescopic rods 54 are closed and drive the three groups of pH meters 55 to be moved upward and reset, thereby completing the concentration and pH value measurement of the three portions of alkali solution.

[0053] During this period, the threaded barrel 47 also drives the blocking covers 62 and the cleaning brushes 64 on the three long curved arms 61 to follow the three short curved arms 51 that are staggered, and synchronously move downward to the adjacent spatial positions of the three groups of filling cups 12. According to actual requirements, when a high-temperature environment is required for the three alkali solutions, the three groups of small electric heaters 56 are controlled to be turned on, and the alkali solutions in the three groups of filling cups 12 are heated by the three groups of electric heating coils 57. Similarly, in order of precedence, the three groups of concentration meters 53 and the three groups of pH meters 55 are respectively controlled to be inserted into the alkali solutions in the three groups of filling cups 12 in a high-temperature state to measure the concentration and pH value, and the concentration and pH value changes of the alkali solutions under normal temperature and high temperature conditions are obtained.

[0054] After the three portions of alkali solution are measured, the alkali solution that has completed the measurement work in the three groups of filling cups 12 is poured into the recycling place, and then the empty three groups of filling cups 12 are placed back in place, the second electric push rod 71 is first controlled to open and drive the second drive bevel gear 72 to move forward to the meshing part of the convex gear ring 73, and then the double-headed motor 41 is controlled to open again and drive the convex gear ring 73 to rotate through the second drive bevel gear 72 that is meshed in place, and the annular slide rail 74 and the supporting slide seat 75 provide sliding support for the rotating seat 2, so that the convex gear ring 73 drives the rotating seat 2 to rotate accordingly, and the rotating seat 2 rotates accordingly in the limiting slide 77 on the three groups of limiting cylinders 76, until the rotating seat 2 drives the empty three groups of filling cups 12 to rotate and transpose to the bottom of the three groups of cleaning brushes 64 through the three groups of placing seats 3, and the double-headed motor 41 is first controlled to pause, and then the second electric push rod 71 is controlled to close and drive the second drive bevel gear 72 to move backward to disengage the meshing part of the convex gear ring 73 to the initial position;

[0055] After the three empty groups of filling cups 12 are rotated and transposed to their positions, similarly, the threaded rod 46 is controlled to drive the threaded cylinder 47 that has been reset to its initial high position to move downward again, and the threaded cylinder 47 drives the blocking covers 62 on the three long curved arms 61 to move downward accordingly. During this period, the three groups of concentration meters 53 and pH meters 55 on the three short curved arms 51 follow the three long curved arms 61 that are staggered and move downward synchronously to the adjacent spatial positions of the three groups of empty filling cups 12 that have been rotated and transposed to their positions, until the blocking grooves 10 in the three groups of blocking covers 62 are closed. The card is moved down until it reaches the edge of the three groups of holding cups 12 that have been rotated into place, and the three groups of small motors 63 are controlled to start and drive the cleaning brushes 64 to rotate and clean the three empty groups of holding cups 12. At the same time, the three groups of small water buckets 65 provide detergent supply, and the water supply pipes 67 on the three three-way joints 66 pass through the water supply port 11 and the three groups of blocking covers 62 to reach the three empty groups of holding cups 12. Then, the three cleaning brushes 64 use the detergent to clean the residual alkali solution attached to the inner wall of the three empty groups of holding cups 12.

[0056] It should be noted that the specific models and specifications of the double-headed motor 41, the first electric push rod 42, the first electric telescopic rod 52, the second electric telescopic rod 54, the small electric heater 56, the small motor 63 and the second electric push rod 71 need to be selected and determined according to the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in the field, so it will not be repeated in detail.
