[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a pH value detection device for an alkali-free liquid quick-setting agent, including a base plate 1 and a detector 2;

[0024] Rotating mechanism 3 is mounted on base plate 1;

[0025] Several fixing parts 4 and cleaning parts 5 are distributed at intervals on the rotating mechanism 3;

[0026] The lifting mechanism 6 is mounted on the base plate 1;

[0027] The detection head 7 is mounted on the lifting mechanism 6 and is electrically connected to the detector 2 via a wire.

[0028] The rotating mechanism 3 is used to drive the fixing part 4 and the cleaning part 5 to rotate, so as to adjust them to the relative position with the detection head 7. The fixing part 4 is used to fix the test tube, and the cleaning part 5 is used to clean the detection head 7. The lifting mechanism 6 is used to drive the detection head 7 to rise and fall, so as to insert it into the test tube for detection and into the cleaning part 5 for cleaning.

[0029] In this embodiment, multiple sample tubes can be inserted one by one into each fixing member 4 during use. Then, the rotating mechanism 3 rotates, causing one sample tube to rotate to below the detection head 7. The lifting mechanism 6 drives the detection head 7 to descend, inserting it into the current test tube to detect the pH value of the alkali-free liquid quick-setting agent sample in the current test tube. After the test is completed, the lifting mechanism 6 drives the detection head 7 to rise, and the rotating mechanism 3 rotates the cleaning member 5 to below the detection head 7. The lifting mechanism 6 then drives the detection head 7 to descend again, inserting it into the cleaning member 5 for cleaning. After cleaning is completed, the lifting mechanism 6 drives the detection head 7 to reset, and the rotating mechanism 3 rotates again to transport the next test tube to below the detection head 7. This process is repeated to sequentially test multiple samples and clean the detection head 7 after each test, avoiding affecting the structure of the next test. Compared with manual methods, this is not only convenient and fast but also more efficient.

[0030] Specifically, refer to Figure 1-2The rotating mechanism 3 includes a rotating ring 31 rotatably mounted on the base plate 1; a toothed ring 32 sleeved on the outer wall of the rotating ring 31; a servo motor 33 mounted on the base plate 1; and a gear 34 mounted on the output shaft of the servo motor 33, wherein the gear 34 and the toothed ring 32 mesh.

[0031] In this embodiment, when the servo motor 33 is powered on, the gear 34 can sequentially drive the gear ring 32 and the rotating ring 31 to rotate. When the rotating ring 31 rotates, the fixing part 4 and the cleaning part 5 rotate accordingly to adjust the two to their relative positions with the detection head 7.

[0032] Specifically, refer to Figure 2 The fixing component 4 includes a fixing cylinder 41 disposed on the rotating ring 31; and a fixing ring 42 disposed inside the fixing cylinder 41, the fixing ring 42 being made of rubber.

[0033] In this embodiment, before use, the bottom of the test tube containing the sample can be inserted into the fixing cylinder 41 and the fixing ring 42 in sequence. During the insertion process, the test tube will squeeze the fixing ring 42 and expand it. After the insertion is completed, the fixing ring 42 will fix the test tube in the fixing cylinder 41 through the elasticity and friction of its own material.

[0034] Specifically, refer to Figure 2 The cleaning component 5 includes a cleaning cylinder 51 disposed on the rotating ring 31; a fixing frame 52 disposed on the outer wall of the cleaning cylinder 51; and a cleaning block 53 disposed on the inner wall of the fixing frame 52.

[0035] In this embodiment, before use, cleaning fluid can be poured into the cleaning tube 51. When the detection head 7 is inserted into the fixing frame 52 and the cleaning tube 51, the cleaning fluid in the cleaning tube 51 will clean the detection head 7, and the cleaning block 53 will wipe the surface of the detection head 7, thus completing the cleaning of the detection head 7.

[0036] Specifically, refer to Figure 3 The lifting mechanism 6 includes two fixed plates 61, with the lower fixed plate 61 on the base plate 1; threaded rods 62 passing through the two fixed plates 61 at both ends; two sliding rods 63 disposed between the two fixed plates 61; a second servo motor 64 disposed on the top of the upper fixed plate 61, with the output end of the second servo motor 64 connected to the top of the threaded rod 62; and a lifting frame 65 sleeved on the outer wall of the threaded rod 62 and the sliding rod 63, with a detection head 7 disposed through the lifting frame 65.

[0037] In this embodiment, when the servo motor 64 is powered on, it can drive the threaded rod 62 to rotate. At this time, the threaded rod 62 drives the lifting frame 65 to lift the detection head 7, and the slide rod 63 can limit and guide the lifting frame 65 during the lifting process.

[0038] Specifically, refer to Figure 1 A fan 8 is installed on the base plate 1, and the output end of the fan 8 is in a relative position to the detection head 7.

[0039] In this embodiment, after the detection head 7 is cleaned, the fan 8 is powered on and blows air onto the surface of the detection head 7 to dry the cleaning liquid adhering to the surface of the detection head 7, thereby avoiding the cleaning liquid from affecting the detection results. At the same time, it is more efficient than natural air drying.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
