[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] like Figure 1-Figure 7 As shown, a wall detection device based on architectural design of the present invention comprises a detection carrier 1; a rubber wheel 11 is rotatably mounted on one side of the detection carrier 1; the rubber wheel 11 can contact with the wall surface to increase the friction between the wall surface, and the rubber wheel 11 is elastic and can also achieve a shock-absorbing effect;

[0049] The auxiliary unit 4 includes a bidirectional threaded rod 41, and the bidirectional threaded rod 41 is fixedly connected to the middle of the two rubber wheels 11;

[0050] The bidirectional threaded rod 41 has a non-threaded portion in the middle, and the threaded portions at both ends are bidirectional threads;

[0051] A reciprocating block 42, which is sleeved on the outer wall of the bidirectional threaded rod 41;

[0052] The rotating member is arranged on one side of the reciprocating block 42 close to the middle of the detection carrier 1 , and the bidirectional threaded rod 41 rotates, and the reciprocating block 42 sleeved on the outer wall thereof drives the rotating member to reciprocate.

[0053] When the rubber wheel 11 contacts the wall and moves along the wall, the rotation of the rubber wheel 11 drives the bidirectional threaded rod 41 to rotate synchronously. At this time, the reciprocating block 42 threadedly connected to the outer wall of the bidirectional threaded rod 41 reciprocates along the outer wall of the bidirectional threaded rod 41. A non-threaded portion is provided in the middle of the bidirectional threaded rod 41. The length of the non-threaded portion is less than the diameter of the rotating roller 46, and the moving directions of the two rotating rollers 46 are synchronized, which can avoid collision between the two rotating rollers 46 and avoid cleaning dead corners of the two rotating rollers 46. At the same time, when the rubber wheel 11 rotates to drive the bidirectional threaded rod 41 to rotate, when the forward distance of the rubber wheel 11 is the same as the length of the rotating roller 46, the rotating roller 46 has just one reciprocating motion cycle along the bidirectional threaded rod 41, and the transmission roller 46 will rotate during the movement. The protruding position of the wall can be smoothed by the rotation of the rotating roller 46, so as to realize the correction of the wall and ensure the flatness of the wall, and at the same time, it is also beneficial to the subsequent detection of the wall.

[0054] Specifically, the rotating member includes a rotating roller 46, which is made of metal and has a diameter between 20cm and 30cm. A diamond protrusion 461 is fixedly provided on the outer wall of the rotating roller 46, and the diameter of the diamond protrusion 461 is between 0.5cm and 0.6cm. The farthest point of the diamond protrusion 461 away from the detection carrier 1 is flush with the farthest point of the rubber wheel 11 away from the detection carrier 1.

[0055] The rotating roller 46 is made of metal and has a diameter between 20cm and 30cm. The longer and heavier the rotating roller 46 is, the greater the load on the power part 22 will be when it moves on the wall surface. It is best to set the rotating roller 46 at 20cm-30cm. When cleaning the wall surface, the preset position can be cleaned quickly. The diamond protrusion 461 meets the standard in hardness and can easily wipe off the protrusions on the wall surface moved out during the wall building process. The diameter of the diamond protrusion 461 is set between 0.5cm-0.6cm for better effect, and the farthest point of the diamond protrusion 461 away from the detection carrier 1 is flush with the farthest point of the rubber wheel 11 away from the detection carrier 1, which can protect the treated wall surface.

[0056] Specifically, the guide track 43 is located between the two rubber wheels 11 , and the end of the reciprocating block 42 is slidably inserted into the guide track 43 .

[0057] The setting of the guide rail 43 can make the reciprocating block 42 more stable during its movement.

[0058] The mating gear 45 is rotatably arranged on one side of the reciprocating block 42;

[0059] A guide rack 44 is disposed on one side of the guide track 43 close to the matching gear 45 , and the guide rack 44 is meshed with the matching gear 45 .

[0060] During the movement of the reciprocating block 42 , a matching gear 45 provided on one side cooperates with the guide rack 44 , and the matching gear 45 rotates. During the rotation process, the matching gear 45 can drive the rotating roller 46 to rotate synchronously.

[0061] Specifically, the rotating roller 46 is hollow to form an inner cavity 463 , and a plurality of through holes 464 are arranged in an array along the circumferential direction of the inner cavity 463 . A pressure nozzle 465 is fixedly provided on the outer wall of the rotating roller 46 , and the pressure nozzle 465 is arranged to penetrate the inner cavity 463 .

[0062] The rotating roller 46 is hollow in design to reduce the overall mass and achieve lightweight. The multiple through holes 464 opened on the side wall of the rotating roller 46 can achieve mechanical lightweight. At the same time, the debris falling from above can be dropped from the through holes 464 to the ground below, avoiding the accumulation of a large amount of debris on the rotating roller 46. During the rotation of the rotating roller 46, the debris will enter the through holes 464 under the action of centrifugal force and then fall to the ground.

[0063] Specifically, a first connecting shaft is fixedly provided on one side of the rotating roller 46 close to the matching gear 45 , and a second connecting shaft 466 is fixedly provided on one side of the matching gear 45 . The first connecting shaft and the second connecting shaft 466 are connected via a universal joint 467 .

[0064] A plurality of damping springs 468 are arranged in an array along the outer circumference of the universal shaft on the side opposite to the first connecting shaft and the second connecting shaft 466 .

[0065] The setting of the universal joint 467 enables the first connecting shaft and the second connecting shaft 466 to rotate relative to each other. When the protrusion on the wall cannot be cleaned by the rotating roller 46 during the rotation process, the rotating roller 46 will rotate along the universal joint 467 to make way due to the obstruction of the protrusion, and the first connecting shaft and the second connecting shaft 466 will rotate relative to each other. At this time, the shock absorbing spring 468 will bend. When passing over the protrusion, under the action of the shock absorbing spring 468, the first connecting shaft and the second connecting shaft 466 will return to the initial state;

[0066] During the normal process of the rotating roller 46 rotating to clean the wall, the shock absorbing spring 468 can play a shock absorbing role.

[0067] Specifically, an air bag 469 is sleeved along the outer side of the universal shaft on the opposite sides of the first connecting shaft and the second connecting shaft 466 , and a plurality of air pipes 460 are fixedly provided at the outlet end of the air bag 469 , and the air pipes 460 extend into the inner cavity 463 .

[0068] The airbag 460 wrapped outside the first connecting shaft and the second connecting shaft 466 can prevent dust from entering during the wall cleaning process, ensure that the first connecting shaft and the second connecting shaft 466 rotate smoothly, and also protect the internal components to prevent rust from entering water;

[0069] When the rotating roller 46 rotates over the protrusion, the airbag will be compressed due to the rotation of the first connecting shaft and the second connecting shaft 466, and the gas will enter the inner cavity 463 through the air pipe 460. The internal pressure will increase. The inner cavity 463 is filled with pigment, which will be sprayed out through the pressure nozzle 465 and sprayed onto the wall for marking, which is convenient for subsequent maintenance by staff.

[0070] A one-way valve is provided in the middle of the air tube 460 of the airbag 469, so that the gas can only enter the inner cavity 463 from the airbag 469.

[0071] The pressure nozzle 465 is a miniature pressure nozzle, which will open under a pressure of 3 Pascals (Pa). The rotating roller 46 is made of metal and can withstand higher pressure, thereby ensuring that the pressure nozzle 465 can work normally.

[0072] Specifically, the first connecting shaft and the second connecting shaft 466 are covered with an outer cover 462, and the outer cover 462 is made of soft leather material.

[0073] The outer cover 462 is made of soft leather material, and the relative rotation between the first connecting shaft and the second connecting shaft 466 is not affected by the outer cover 462. The setting of the outer cover 462 can further prevent the entry of dust, ensuring that the first connecting shaft and the second connecting shaft 466 can work normally for a long time. Secondly, the outer cover 462 has a guiding function, which can make the fallen debris slide along the outer wall into the through hole 464.

[0074] Specifically, a plurality of motors 3 are fixedly connected to the middle of the detection carrier 1 , and a cleaning brush 31 is fixedly connected to the output end of the motor 3 .

[0075] A plurality of ultrasonic detectors 6 are fixedly disposed on one side of the detection carrier 1 .

[0076] The cleaning brush 31 is driven to rotate by the motor 3, wherein the cleaning brush can clean the wall surface, so that the subsequent ultrasonic detector 6 can detect more accurately. The arc-shaped guard plate 5 arranged above the ultrasonic detector 6 can play a protective role. The debris falling from the top is scattered to both sides along the arc-shaped guard plate 5. The arc-shaped guard plate 5 can also contact with the wall surface to further clean the flatness of the wall surface. The scraper 49 can also smooth the wall surface and spread the newly sprayed paint at the same time, so that the staff can find it in time.

[0077] Specifically, a laser detector 47 is fixedly disposed on one side of the reciprocating block 42 away from the middle of the detection carrier 1 .

[0078] The laser detector 47 is set to detect the flatness of the wall during the process of detecting wall cracks. When the distance between the position where the light falls on the ground and the wall is greater than the distance between the laser detector 47 and the rubber wheel 11, the wall may be tilted.

[0079] Specifically, a thrust wing 21 and a power member 22 are provided on a side of the detection carrier 1 away from the rubber wheel 11 .

[0080] The thrust wing 21 can make the device contact and press against the wall; the power member 22 can control the movement of the device;

[0081] The thrust wing 21 and the power part 22 both generate thrust by driving the fan blades to rotate through the motor; the overall weight of the detection devices of different weight models is different, and the fan blade power required to be matched is different, see Table 1 for details:

[0082] Table 1 The corresponding fan blade power table of different weight models of detection devices

[0083] Detection device Mass (kg) Fan power (W) 1 15 200 2 20 250 3 25 300 4 30 350 5 35 400

[0084] The thrust wing 2 and the power member 22 provide power for the device, so that the device can smoothly reach a height that is not conducive to observation by staff, thereby increasing the detection range.

[0085] The present invention also provides a wall detection method based on architectural design, comprising the following steps:

[0086] S1: Clean the wall surface to remove impurities and moisture that may affect the propagation of ultrasonic waves;

[0087] Clean the wall surface to remove impurities and moisture on the surface, which is conducive to ultrasonic detection;

[0088] S2: Select appropriate ultrasonic equipment and mark the crack location to be detected on the wall;

[0089] Select the appropriate ultrasonic testing instrument to ensure that the instrument accuracy meets the testing requirements

[0090] S3: The crack passes through the transmitting probe and the receiving probe;

[0091] According to the length and distribution of the cracks, perform multiple inspections at multiple points to improve the comprehensiveness and accuracy of the inspection. Set the ultrasonic detector's transmission frequency, receiving sensitivity and other parameters to ensure that a clear signal can be obtained;

[0092] According to the acoustic properties of the wall material, select the appropriate ultrasonic waveform (such as longitudinal wave, transverse wave, etc.).

[0093] S4: The length and distribution of the crack, and the reasonable arrangement of multiple measuring points.

[0096] S6: Calculate the depth and width of the crack using a specific algorithm or formula based on the ultrasonic propagation time and the acoustic parameters of the wall material.
