[0002] In the construction of clean areas in pharmaceutical factories, the flatness of the building floor is one of the key factors affecting the quality of the clean environment. Poor floor flatness may lead to problems such as dust and water accumulation, which in turn affects the quality and safety of pharmaceutical production. Therefore, accurate testing of floor flatness is crucial.

[0020] 4.

The entire device can be moved by the movable base 1;

[0034] As an embodiment of the present invention, it also includes a driving mechanism, which is used to drive the detection mechanism to rotate. In this way, a single point can be repeatedly detected to reduce the detection error.

[0035] As an embodiment of the present invention, it also includes a pre-inspection mechanism, which is used to ensure the accuracy of the operation of the detection mechanism. The pre-inspection mechanism includes a horizontal plate 27 fixedly connected to the left side of the mobile base 1, a rectangular bar 11 is fixedly connected to the left side of the horizontal plate 27, a slide 14 is provided at the upper end of the rectangular bar 11, a reciprocating screw 12 is rotatably connected between the front and rear inner walls of the slide 14, a slider 13 is threadedly connected to the reciprocating screw 12, the slider 13 is slidably connected to the inner wall of the slide 14, and an L-shaped bar 40 is fixedly connected to the upper end of the slider 13. A sponge layer is installed at the upper left end of the horizontal portion of the mounting strip 40. The rear end of the reciprocating screw 12 extends to the outside and is fixedly connected to the second bevel gear 26. The lower end of the rotating shaft 24 is installed with a first bevel gear 25 through a second one-way bearing. By utilizing the arrangement of the first bearing and the second bearing, when the drive motor 9 rotates forward, it will rotate the detection mechanism through the belt transmission member 10 (the pre-inspection mechanism does not operate), and when the drive motor 9 rotates reversely, the pre-inspection mechanism operates, and it will not rotate the detection mechanism through the belt transmission member 10;

[0036] As an embodiment of the present invention, the upper end of the vertical plate 2 is fixedly connected to the hollow plate 15, and the upper end of the hollow plate 15 is symmetrically fixedly connected to two handles 17. The two handles 17 are hollow and communicated with the hollow plate 15. A plurality of exhaust ports 21 are opened on the outside of each handle 17, and a support ring 22 is provided on the outside of each handle 17. The upper end of the connecting plate 4 is fixedly connected to the piston cylinder 36, the upper end of the rotating tube 5 passes through the L-shaped mounting plate 3, and the lower end of the rotating tube 5 is communicated with the mounting groove. The second piston plate 39 is slidably connected between the front and rear inner walls of the piston cylinder 36, and the front side of the second piston plate 39 is elastically connected to the front inner wall of the piston cylinder 36 through the second spring 23. The spring coefficient of the second spring 23 is greater than the spring coefficient of the first spring 29 Degree coefficient, the rear side of the second piston plate 39 is fixedly connected with a round head push rod 38, the output shaft of the drive motor 9 is installed with a cam 37, the round head push rod 38 cooperates with the cam 37, and the right side of the vertical plate 2 is fixedly connected with a gas storage cylinder 18, and a first piston plate 30 that can slide up and down is provided in the gas storage cylinder 18. The upper end of the first piston plate 30 is elastically connected to the inner top of the gas storage cylinder 18 through a first spring 29, and a connecting port 34 is provided on the inner top of the gas storage cylinder 18. The front space of the piston cylinder 36 is connected with the first one-way tube 20, and the other end of the first one-way tube 20 is connected with the upper end of the rotating tube 5 through a rotary joint 19. The front space of the piston cylinder 36 is connected with the inner bottom space of the gas storage cylinder 18 through the second one-way tube 35;

[0037] As an embodiment of the present invention, the middle space of the gas storage cylinder 18 is connected to the interior of the hollow plate 15 through a connecting pipe, and a one-way valve is installed inside the first one-way tube 20 and the second one-way tube 35. The one-way valve inside the first one-way tube 20 flows in a one-way direction from the rotating tube 5 to the front space of the piston cylinder 36, and the one-way valve inside the second one-way tube 35 flows in a one-way direction from the front space of the piston cylinder 36 to the inner bottom space of the gas storage cylinder 18. As the driving motor 9 rotates, it drives the cam 37 to rotate. Under the elastic action of the second spring 23, the round head push rod 38 will always be against the cam 37. In this way, the rotation of the cam 37 will cause the second piston plate 39 to reciprocate back and forth. By using the first one-way tube 20 and the second one-way tube 35, a The gas flows in one direction among the outside, the mounting groove, the piston cylinder 36 and the inner bottom space of the gas storage cylinder 18. As the gas gathers, the first piston plate 30 moves upward and compresses the first spring 29 (it should be noted that the gas supply speed is relatively fast. Even if the solenoid valve 32 is always open, the gas can also gather in the inner bottom space of the gas storage cylinder 18). When the first piston plate 30 moves upward to a position higher than the connection between the connecting pipe and the gas storage cylinder 18, the excess gas will enter the hollow plate 15 through the connecting pipe and finally be discharged from the exhaust port 21 of the grip 17 to dissipate heat to the palm of the hand holding it. In addition, the above-mentioned gas flow can also replace the gas in the mounting groove, so as to avoid the heat accumulation inside the mounting groove after long-term use, thereby affecting the service life of the infrared ranging head 28.

[0038] As an embodiment of the present invention, the inner bottom space of the gas storage cylinder 18 is connected to the outside world through a release tube 31, a solenoid valve 32 is installed inside the release tube 31, and a whistle 33 is installed at the end of the release tube 31. A display panel 16 is installed on the right side of the hollow plate 15, and a controller is integrated inside the display panel 16. The controller is electrically connected to multiple infrared ranging heads 28 and the solenoid valve 32. When multiple infrared ranging heads 28 are started, the detection data will be displayed on the display panel 16, and the user only needs to observe whether the data on the display panel 16 changes. Furthermore, when different data appear in multiple data, the solenoid valve 32 will also open, causing part of the gas in the bottom space of the gas storage cylinder 18 to be released through the release tube 31, and the gas makes a sound through the whistle 33 to remind the user, further improving the reminder effect when it is uneven.

[0039] In the present invention, the entire device can be moved to the ground position that needs to be detected in the clean area of the pharmaceutical factory by moving the moving wheels of the mobile base 1. A pre-inspection is first performed. During the pre-inspection, the multiple infrared ranging heads 28 are first opened, and then the driving motor 9 rotates in the opposite direction. At this time, through the cooperation of the first one-way bearing and the second one-way bearing, the pre-inspection mechanism runs but the detection mechanism does not rotate. The driving motor 9 drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the reciprocating screw 12 to rotate through the engagement of the first bevel gear 25 and the second bevel gear 26. The rotation of the reciprocating screw 12 causes the slider 13 to slide back and forth in the slide groove 14, thereby driving the sponge layer at the upper left end of the horizontal part of the L-shaped strip 40 to move backward. During the movement, the sponge layer part of the L-shaped strip 40 will sequentially block the multiple infrared ranging heads 28. Observe the data on the display panel 16 to see whether the data of the multiple infrared ranging heads 28 change in sequence, so as to judge whether the infrared ranging heads 28 can be used normally.

[0040] Furthermore, the driving motor 9 rotates to drive the cam 37 to rotate. Under the elastic action of the second spring 23, the round head push rod 38 always resists the cam 37, causing the second piston plate 39 to reciprocate back and forth in the piston cylinder 36, and through the first one-way tube 20 and the second one-way tube 35, a one-way gas flow is generated in the outside world, the mounting groove, the piston cylinder 36 and the bottom space of the gas storage cylinder 18. If the detection data of the multiple infrared ranging heads 28 are different, the solenoid valve 32 is opened at this time, and part of the gas is released through the release tube 31. At this time, the wind whistle 33 will make a sound to warn. The user can also judge whether the infrared ranging head 28 can be used normally by listening to whether the wind whistle 33 occurs. At the same time, during the movement of the L-shaped strip 40, the sponge layer thereon will also wipe the light-transmitting glass 8 to ensure its cleanliness, thereby ensuring the accuracy of subsequent detection;

[0041] After the pre-inspection is completed, the driving motor 9 rotates forward, which drives the rotating tube 5 to rotate through the belt transmission member 10, and then drives the installation box 6 to rotate. When the installation box 6 rotates, the multiple infrared ranging heads 28 in the installation slot at the lower end thereof rotate rapidly. The rapid rotation of the multiple infrared ranging heads 28 can achieve an effect similar to a detection surface, avoiding the occurrence of detection blind spots. At the same time, single points can be repeatedly detected, thereby improving the actual detection accuracy. During the detection process, the staff can judge whether there are any uneven places by observing the display panel 16 or listening to whether the wind whistle 33 makes a sound;

[0042] In the above process, as the gas is continuously injected into the bottom space of the gas storage cylinder 18, the gas accumulates and causes the first piston plate 30 to move upward to compress the first spring 29. When the first piston plate 30 moves up to a position higher than the connection point between the connecting pipe and the gas storage cylinder 18, the excess gas enters the hollow plate 15 through the connecting pipe and is finally discharged from the exhaust port 21 of the handle 17, dissipating heat to the palm of the holder. At the same time, the gas flow can replace the gas in the installation groove, thereby avoiding internal heat accumulation affecting the service life of the infrared ranging head 28.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
