[0002] Walls are divided into load-bearing walls and non-load-bearing walls. Their core function is to enclose and divide space. The walls of load-bearing structures also have the function of bearing weight, and the walls must have sufficient strength, stability, and properties such as heat insulation, sound insulation, fire resistance, and waterproofing. With the development of building construction, the flatness of the wall surface is crucial to the subsequent wall decoration and processing.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1, referring to Figure 1 - Figure 2 The first embodiment of the present invention provides a wall flatness detection device for civil engineering. The device includes: a housing 1 and a horizontal unit 2 fixedly installed on the housing 1 for performing horizontal detection of the whole, and an adjustment unit 3 rotatably installed on the housing 1. The adjustment unit 3 is fixedly connected to the horizontal unit 2 and is used for adjustment and leveling after the horizontal detection is completed.

[0029] The leveling unit 2 includes a support component 21 fixedly installed at the bottom of the housing 1 for supporting the entire level, and a trigger component 22 slidably installed on the support component 21. The trigger component 22 is slidably connected to the housing 1 and is used to cooperate with the support component 21 to detect the flatness of the ground when providing support, and to trigger the adjustment unit 3 to level the ground through the trigger component 22.

[0030] Preferably, the adjustment unit 3 includes an adjustment component 31 rotatably mounted on the inner wall of the housing 1 for cooperating with the trigger component 22 to drive after detecting uneven ground, and a drive component 32 fixedly mounted on the adjustment component 31. The drive component 32 is fixedly connected to the housing 1 and cooperates with the drive component 32 to drive the adjustment component 31 to start horizontal adjustment.

[0031] During use, when testing the flatness of the wall surface, the support component 21 is placed on the ground. If the ground is uneven, the trigger component 22 will begin to tilt under the influence of gravity, triggering the drive component 32 to drive it. The drive component 32 then drives the adjustment component 31 to adjust. During this process, the trigger component 22 moves together with the adjustment component 31. When the adjustment component 31 completes the leveling, the trigger component 22 returns to a vertical state. At this point, the drive component 32 is released, and it stops working. The adjustment component 31 remains in its adjusted state, thus achieving overall leveling. This mechanism not only solves the problems of traditional testing tools having high requirements for the angle of placement on the ground and being easily affected by debris and uneven ground, leading to inaccurate measurement data, but also simplifies the operation process, reduces manual intervention, and significantly improves the accuracy and efficiency of the test data.

[0032] In confined spaces such as attics where the floor is uneven, the support component 21 can be placed directly on the attic floor or a temporary platform without the need for additional leveling. The device can quickly detect the floor tilt and automatically adjust it via the trigger component 22. Even if there are beams or columns obstructing the view or the operating space is limited, its automatic leveling feature can quickly locate the reference point and efficiently complete the attic wall flatness test, meeting the construction needs of special scenarios.

[0033] Example 2, refer to Figure 1 - Figure 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the support component 21 includes a base 211 fixedly installed at the bottom of the housing 1, which supports the fixed bracket 212 and connects to the housing 1, and a fixed bracket 212 fixedly installed at the bottom of the base 211 for providing support on the ground.

[0034] Compared to Embodiment 1, the base 211 further includes an inclined groove 216 for tilting adjustment in conjunction with the mounting component 221; the base 211 also includes a sliding groove 213 for sliding with the telescopic rod 214. The telescopic rod 214 is slidably installed inside the sliding groove 213. One end of the telescopic rod is connected to a fixing collar 215 to achieve telescopic function, and the other end is fixedly installed with the fixing collar 215. The fixing collar 215 is fixedly connected to the connecting rod 225. When the connecting rod 225 detects uneven ground, it tilts, and the fixing collar 215 tilts synchronously with the telescopic rod 214 to limit movement.

[0035] In addition, the trigger assembly 22 includes a mounting member 221 slidably installed inside the tilting groove 216 for adjusting the tilt of the connecting rod 225; a connector 222 fixedly installed at the bottom of the mounting member 221 for connecting the mounting member 221 and the connecting elastic rope 223; and a drive switch 228 fixedly installed on the inner wall of the connector 222, which is fixedly connected to the mounting member 221 for driving the cooperating drive assembly 32 to work.

[0036] Furthermore, a connecting elastic rope 223 is fixedly installed at the bottom of the connector 222 for returning to its original position when the connecting rod 225 is tilted or adjusted. A fixing collar 224 is fixedly installed at the other end of the connecting elastic rope 223 for connecting the connecting rod 225. The connecting rod 225 is fixedly installed inside the fixing collar 224 for moving in conjunction with the gravity ball 226. The gravity ball 226 is fixedly installed at the bottom of the connecting rod 225 for automatic horizontal detection under gravity. A main laser 229 is fixedly installed at the top of the mounting part 221 and is slidably connected to the housing 1 for laser detection of the wall surface. At the same time, the outer wall of the connecting rod 225 is fixedly connected to the fixing collar 215 for limiting the movement of the connecting rod 225.

[0037] Furthermore, a trigger block 227 is fixedly installed on the top of the connecting rod 225, and the trigger block 227 is slidably connected to the drive switch 228. When the connecting rod 225 moves, the trigger block 227 moves accordingly and presses the drive switch 228, so that the drive assembly 32 performs drive leveling.

[0038] During use, when testing the flatness of the wall surface, the fixed bracket 212 is placed on the ground. The fixed bracket 212 moves according to the ground conditions. If the ground is uneven, the gravity ball 226 moves the connecting rod 225 under the action of gravity. At the same time, the movement of the connecting rod 225 causes the fixed collar 215 and the telescopic rod 214 to move inside the sliding groove 213 to cooperate with the movement of the connecting rod 225. The trigger block 227 at the top of the connecting rod 225 also moves, pressing the drive switch 228. The drive switch 228 sends a signal to the drive assembly 32, and the drive assembly 32 adjusts the level of the adjustment assembly 31.

[0039] After the adjustment component 31 completes the horizontal adjustment with the cooperation of the drive component 32, the mounting component 221 moves back to the horizontal state with the adjustment component 31. At the same time, the connector 222 and the connecting elastic rope 223 at the bottom of the mounting component 221 cause the connecting rod 225 and the gravity ball 226 to return to their original positions. The gravity ball 226 becomes vertical again under the action of gravity, and the trigger block 227 also becomes vertical and slides out from the drive switch 228, canceling the control of the drive component 32. The drive component 32 stops driving, the adjustment component 31 remains horizontal, and the overall leveling is completed. The flatness detection of the wall surface begins, which simplifies the operation process, reduces manual intervention, improves the accuracy and efficiency of the detection data, and is suitable for wall detection scenarios in various civil engineering sites.

[0040] The remaining structure is the same as that in Example 1.

[0041] Example 3, referring to Figure 1 - Figure 8 This is the third embodiment of the present invention, which differs from the second embodiment in that: the adjustment assembly 31 includes a rotating shaft 311 fixedly installed on the inner wall of the housing 1 for rotating and limiting the movable plate 312; the movable plate 312 fixedly installed on the rotating shaft 311 for receiving the auxiliary laser 313 and performing horizontal adjustment; and the auxiliary laser 313 fixedly installed on the rotating shaft 311, which is slidably connected to the housing 1 and cooperates with the main laser 229 to detect the flatness of the wall surface.

[0042] Compared to Embodiment 2, the bottom of the movable plate 312 is further fixedly equipped with a connecting rod 314, and the other end of the connecting rod 314 is fixedly connected to the mounting component 221 to drive the mounting component 221 to move and adjust together.

[0043] The drive assembly 32 includes an adjustment shaft 321 fixedly mounted on the movable plate 312 for connecting and driving one end of the movable plate 312 to move; an adjustment rod 322 rotatably mounted on the inner wall of the adjustment shaft 321 for adjusting the movable plate 312 during movement; and an adjustment nut 323 rotatably mounted on the other end of the adjustment rod 322 for driving the movable plate 312 to adjust.

[0044] Furthermore, a motor 325 is fixedly installed on the top of the housing 1 to drive the lead screw 324 to rotate. The lead screw 324 is fixedly installed at the output end of the motor 325, and the outer wall of the lead screw 324 is engaged with the adjusting nut 323 to drive the adjusting nut 323 to move. A limit plate 326 is fixedly installed on the inner wall of the housing 1. The limit plate 326 is rotatably connected to the lead screw 324 and slidably connected to the adjusting rod 322 to limit the movement of the adjusting rod 322.

[0045] During use, when the gravity ball 226 shifts, the connecting rod 225 and the trigger block 227 press the drive switch 228. The drive switch 228 controls the motor 325 to start, and the motor 325 drives the lead screw 324 to rotate. At the same time, the adjusting nut 323 moves upward, causing the adjusting rod 322 and the adjusting shaft 321 to move upward together. The rotation of the adjusting shaft 321, in conjunction with the upward movement of the adjusting rod 322, causes the moving plate 312 to move upward. Since one end of the moving plate 312 is connected to the rotating shaft 311, it can only move at one end, while the other end rotates in conjunction with the rotating shaft 311. Through the movement of the moving plate 312, the secondary laser 313 is adjusted accordingly.

[0046] Simultaneously, the connecting rod 214 at the bottom of the moving plate 312 drives one end of the mounting piece 221 to move upward, while the other end tilts towards the inclined groove 216, causing the main laser 229 to be adjusted horizontally in sync. The mounting piece 221 drives the connecting piece 222 and the connecting elastic rope 223 to move. The connecting elastic rope 223, in conjunction with the fixing collar 224, pulls back the connecting rod 225 and the gravity ball 226, restoring them to a vertical state. When the connecting rod 225 and the gravity ball 226 are restored to a vertical state, the trigger block 227 disengages from the drive switch 228, and the drive switch 228 disconnects the motor 325 control, completing the automatic leveling. This avoids the problems of traditional testing tools having high requirements for the angle of placement on the ground and being easily affected by debris and uneven ground, leading to inaccurate measurement data. At the same time, it simplifies the operation process and enhances practicality.

[0047] The remaining structure is the same as that in Example 2.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
