when the work is needed, the user holds the handle 20 to push the box body 15 to the constructed blank room, at this time, the main switch 60 is pressed, at this time, the air extractor 41 rotates forwards and sucks a certain amount of air from left to right, at the same time, the rotating rod 43 rotates anticlockwise under the action of wind power, the air is sucked into the test cavity 36 from the outside through the dust cavity 42, when the air extractor 41 sucks the air into the test cavity 36 quantitatively, the air extractor 41 stops rotating forwards, dust in the air is accumulated on the upper surface of the sliding plate 40, the weight of the sliding plate 40 is increased and slides downwards along the inner wall of the test cavity 36, the telescopic spring 38 is further pulled up, at the same time, the sliding shaft 39 slides downwards and the scales are exposed in the detection range of the scale detector 54, then the scale detector 54 calculates the detected scale number and calculates the weight, further calculates the dust concentration in the quantitative air and transmits the dust concentration to the display screen 21 for display, after each display is completed, the display screen 21 transmits, further, the air extractor 41 rotates reversely to extract the dust on the surface of the sliding plate 40 and in the test cavity 36, and the dust passes through the dust cavity 42 and the rotating rod 43 to the outside, and the air extractor 41 rotates forward automatically again after a certain time to extract the air, and the test is performed again; if the height of the raised ground block needs to be tested, the box body 15 needs to be pushed, in the moving process of the box body 15, when the box body 15 touches the raised part, the moving shaft 48 rotates and moves upwards in engagement with the threads of the long plate 49, so that the friction block 45 moves upwards, the memory spring 46 is compressed, in the upward movement process of the moving shaft 48, the scale block 50 slides upwards along the partition plate 56, the scale marks on the partition plate 56 are exposed to the detection range of the height detector 55, the height detector 55 detects the number of the scale marks and obtains the ascending distance of the partition plate 56, meanwhile, the box body 15 continues to move leftwards and rightwards, the friction block 45 is separated from the raised ground part at a certain moment, at this moment, under the resilience action of the memory spring 46, the friction block 45 moves downwards, the moving shaft 48 rotates reversely and moves downwards, the scale block 50 slides downwards along the partition plate 56, and the scale marks on the scale block 50 leave the detection range of the height detector 55, until the memory spring 46 returns to the initial position, the height detector 55 detects the maximum number of scale marks in the period from the appearance of the measurement line on the partition plate 56 to the disappearance of the measurement line, the maximum upward sliding distance of the scale block 50 in the period is calculated, the maximum upward sliding length of the scale block 50 is the height of the ground bulge, and the value is transmitted to the display screen 21; if the wall surface roughness test is to be performed, firstly, the box body 15 is pushed to the wall side by manpower, the left end surface of the box body 15 is parallel to the wall surface, the rotating switch 61 is pressed, the energy storage motor 18 is further started, the driving shaft 33 is further driven to rotate, the driving belt pulley 19 is further driven to rotate, the driven belt pulley 35 is further driven to rotate under the connecting action of the belt 16, the driven shaft 34 is further driven to rotate, the cam 13 is further driven to rotate, the air cylinder 29 is further pushed to rotate around the fixing rod 24, the long rod 12 and the disc 11 rotate along with the rotation, the supporting spring 51 is simultaneously stretched, when the disc 11 contacts the wall surface and is parallel to the wall surface under the combined action of the cam 13 and the wall surface, the cam 13 cannot rotate any more, namely, the energy storage motor 18 cannot rotate any more, at the time, the energy storage motor 18 automatically stops rotating, when the disc 11 is parallel to the wall, further compressing the memory spring 32, if the wall surface is very flat and smooth, the memory spring 32 is compressed to a certain position, at this time, the left end point of the telescopic block 30, the left surface of the disc 11 and the wall surface are positioned on the same plane, and at this time, the roughness is zero; if the wall surface has a pit at a certain position, the memory spring 32 is compressed to a certain position, at this time, the left end point of the telescopic block 30 is positioned outside the circular groove 31 and contacts the wall surface at the certain position, and at this time, the memory spring 32 judges the roughness according to the compressed distance; if a certain position of the wall surface is convex, the memory spring 32 is compressed to a certain position, the left end point of the telescopic block 30 is positioned in the circular groove 31 and contacts with the position of the wall surface, the memory spring 32 judges the roughness according to the compressed distance, finally the memory spring 32 transmits the calculated roughness average value to the display screen 21 for display, when the disc 11 completes the test of the roughness of the area and transmits data to the display screen 21, the display screen 21 transmits a signal to the energy storage motor 18, the energy storage motor 18 is automatically started and reversed, the cam 13 reversely rotates and returns to the initial position, the air cylinder 29 clockwise rotates and returns to the initial position under the effect of the resilience force of the supporting spring 51, the energy storage motor 18 automatically stops, and the test is completed; when the disc 11 needs to perform a roughness test on a higher wall surface, the pneumatic switch 62 is pressed for a long time, the air pump 25 is started and enables air to enter the air cavity 52 through the soft air pipe 26, and then the sliding block 27 slides upwards, so that the long rod 12 and the disc 11 move upwards, the pneumatic switch 62 is loosened when the target operation position is reached, the air pump 25 stops operating, when the operation of the disc 11 is completed, the pneumatic switch 62 is pressed for a long time again, at the moment, the air pump 25 rotates reversely to pump out the air at the lower end of the sliding block 27 along the soft air pipe 26, and at the moment, the sliding block 27 slides downwards.
The invention has the beneficial effects that: the device detects the air quality, the ground flatness and the wall surface roughness in an unfinished blank room, and automatically detects the dust amount in a certain air volume in the environment at intervals, so that the aim of detecting the air quality is fulfilled; when the hand-pushing device moves and passes through the ground bump, the device displays the height of the bump measured on the display screen; the extension and the rotation of the long rod realize the accurate measurement of the roughness of each position on the wall surface.
In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
