Figures 1 to 5 The lower end of the equipment shell 1 is fixedly connected with a limiting plate 18, the limiting plate 18 is fixedly installed on the upper side of the mounting seat 5, the lower surface of the mounting seat 5 is fixedly connected with three groups of fourth transmission blocks 51, the lower side of the mounting seat 5 is rotatably connected with three groups of supporting rods 52, the upper end of the supporting rod 52 is rotatably connected with the fourth transmission block 51, the side surface of the fourth transmission block 51 is fixedly connected with an abutting block 53, the surface of the equipment shell 1 is provided with a detection assembly, the detection assembly comprises a storage battery 11, a display panel 14, a warning light 15, a buzzer 16, a controller 112, a mounting rod 2 and a laser sensor 4, and the display panel 14, the warning light 15, the buzzer 16 and the laser sensor 4 are electrically connected with the storage battery 11 and the controller 112.

[0031] In use, the three groups of supporting rods 52 are unfolded, the mounting seat 5 is erected on the upper side of the concrete formwork, the supporting rod 52 is made of stainless steel, the influence on the concrete pouring is reduced, then the equipment shell 1 and the limiting plate 18 are fixedly installed on the upper side of the mounting seat 5, the mounting rod 2 is unfolded, and the pouring height is set in the controller 112, at this time, the laser sensor 4 continuously detects the distance between the laser sensor 4 and the formwork during the pouring process, and the height of the concrete is calculated by the controller 112, and the height of the concrete is detected in real time.

[0032] Referring to Figures 3 to 10 The storage battery 11 is fixedly installed in the equipment shell 1, the upper end of the equipment shell 1 is threadedly connected with a sealing cover plate 12, the controller 112 is fixedly connected with the inner side surface of the sealing cover plate 12, the upper surface of the sealing cover plate 12 is fixedly connected with a connecting seat 13, the display panel 14 is fixedly installed at the upper end of the connecting seat 13, three groups of warning lights 15 are fixedly connected with the position close to the upper end of the side surface of the equipment shell 1, the lower side of each of the three groups of warning lights 15 is fixedly connected with a buzzer 16, a sliding groove 25 is formed in the inside of the mounting rod 2, a sliding rod 26 is slidably connected in the inside of the sliding groove 25, a mounting block 27 is fixedly connected with one end outside of the sliding rod 26, a plug-in female groove 28 is formed in the inner wall of the mounting block 27, a plug-in male head 41 is fixedly connected with the side surface of the laser sensor 4, and the plug-in male head 41 is plug-in fixed with the plug-in female groove 28.

[0033] Specifically, the laser sensor 4 first emits a laser beam onto the surface of the template, which is then reflected and captured by the receiver. The controller 112 collects distance data in real time and calculates the distance value using the time-of-flight method, thereby measuring the initial distance. During the concrete pouring process, the laser beam is continuously emitted onto the concrete surface to continuously measure the height of the concrete. At the same time, the pouring thickness is calculated in conjunction with a preset reference surface, and the concrete height is displayed in real time on the display panel 14, allowing workers to observe the pouring height of the concrete in a timely manner. Simultaneously, when the thickness deviation exceeds the set threshold, an alarm is triggered. At this time, the controller 112 controls the warning light 15 to flash and the buzzer 16 to emit a humming sound to remind the construction personnel, thereby adjusting the concrete pouring height, improving the concrete pouring accuracy, facilitating the subsequent leveling of the concrete surface, reducing the concrete leveling time, and effectively improving the efficiency of concrete pouring construction.

[0034] Example 2: See Figure 3 and Figure 7 Three sets of mounting rods 2 are installed on the side of the equipment housing 1. A first transmission block 21 is rotatably connected to one end of the inner side of the mounting rod 2. The first transmission block 21 is fixedly connected to the side of the equipment housing 1. A second transmission block 22 is fixedly connected to the middle position of the mounting rod 2. A first connecting sleeve 23 is fixedly connected to the upper surface of the mounting rod 2 near the outer end. A first locking screw 24 is connected to the internal thread of the first connecting sleeve 23. A limit ring 3 is slidably connected to the surface of the equipment housing 1. Three sets of third transmission blocks 33 are fixedly connected to the side of the limit ring 3. A transmission rod 34 is rotatably connected to the upper end of the third transmission block 33. The upper end of the transmission rod 34 is rotatably connected to the second transmission block 22. A limit block 17 is fixedly connected to the middle position of the side of the equipment housing 1. A second connecting sleeve 31 is fixedly connected to the side of the limit ring 3. A second locking screw 32 is connected to the internal thread of the second connecting sleeve 31.

[0035] Simultaneously, during the unfolding of the detection component, the mounting rod 2 is directly rotated upward around the first transmission block 21. At this time, the mounting rod 2 will drive the limiting ring 3 to slide upward through the cooperation of the second transmission block 22, the transmission rod 34, and the third transmission block 33. When the upper end of the limiting ring 3 abuts against the limiting block 17, the mounting rod 2 just rotates to a horizontal position. Then, the second locking screw 32 is rotated inward to abut against the surface of the equipment housing 1, locking and fixing the limiting ring 3. At this time, the limiting ring 3, the third transmission block 33, the transmission rod 34, and the second transmission block 22 cooperate to support and fix the mounting rod 2, keeping the mounting rod 2 horizontal. Next, the sliding rod 26 is pulled outward. When the sliding rod 26 is pulled to the outermost end, the first locking screw 24 is rotated downward to abut against the surface of the sliding rod 26, locking and fixing the sliding rod 26. This effectively improves the detection range of the laser sensor 4, and at the same time facilitates the folding and storage of the equipment, thus making it easier to carry, transport, and install.

[0036] Example 3: See Figures 4 to 6 and Figures 11 to 13 The lower surface of the limiting plate 18 is fixedly connected with two sets of connecting blocks 19. Insertion slots 110 are provided on both the left and right sides of the lower surface of the limiting plate 18. A snap-fit ​​slot 111 is provided on the opposite side of the insertion slot 110 near the upper end. The upper surface of the mounting base 5 is provided with two sets of connecting slots 54. The side of the mounting base 5 is provided with two sets of symmetrically distributed positioning slots 55. A positioning block 57 is slidably connected inside the positioning slot 55. A positioning hole 510 is provided at one end of the inner side of the positioning block 57. A positioning rod 51 is fixedly connected to one end of the inner side of the positioning slot 55. 1. The positioning rod 511 is slidably connected to the positioning hole 510. A positioning spring 512 is sleeved on the surface of the positioning rod 511. The two ends of the positioning spring 512 abut against the inner wall of the positioning groove 55 and the side wall of the positioning block 57, respectively. Limiting grooves 56 are opened on both the left and right sides of the upper surface of the mounting base 5. The lower end of the limiting groove 56 is connected to the positioning groove 55. A limiting rod 58 is slidably connected inside the limiting groove 56. The lower end of the limiting rod 58 is fixedly connected to the positioning block 57. A snap-fit ​​block 59 is fixedly connected to the upper end of the limiting rod 58. The side of the snap-fit ​​block 59 is inclined.

[0037] In addition, during the installation of the limiting plate 18 and the mounting base 5, the equipment housing 1 and the limiting plate 18 are placed directly on the upper side of the mounting base 5, and the connecting block 19 is aligned with the connecting groove 54 and pressed down to insert the connecting block 19 into the interior of the connecting groove 54. At the same time, when the connecting block 19 is aligned with the connecting groove 54, the insertion groove 110 is located on the upper side of the limiting rod 58 and the snap-fit ​​block 59. When the limiting plate 18 is pressed down, the snap-fit ​​block 59 and the limiting rod 58 will be inserted into the interior of the insertion groove 110. When the snap-fit ​​block 59 is inserted into the uppermost end of the insertion groove 110, it will automatically snap into the interior of the snap-fit ​​groove 111 under the action of the positioning spring 512, thereby locking and fixing the limiting plate 18 and the mounting base 5.

[0038] Conversely, when disassembling the device, the positioning blocks 57 on both sides are pressed inward simultaneously. As the positioning blocks 57 slide inward, they drive the limiting rod 58 and the locking block 59 to slide inward, causing the locking block 59 to disengage from the inside of the locking groove 111. This allows the device housing 1 and the limiting plate 18 to be pulled upward directly for disassembly, effectively improving the ease of disassembly and assembly and further enhancing the ease of use of the device.

[0039] The working principle of this invention is as follows: By using the support rod 52 and the mounting base 5 to fix the equipment shell 1 and the detection component to the upper side of the building formwork, the detection component will detect the initial height. As the concrete is continuously poured, the detection component will continuously detect the height of the concrete and display it on the surface of the display panel 14, so that the staff can more intuitively observe the height of the concrete. When the concrete reaches the threshold, the warning light 15 and the buzzer 16 will sound an alarm to remind the staff, which effectively improves the flatness of the concrete pouring, reduces the later leveling time, and improves the construction efficiency. At the same time, the mounting rod 2 can rotate around the equipment shell 1, the sliding rod 26 can slide inside the sliding groove 25, and the equipment shell 1 and the mounting base 5 can be disassembled, which makes it easy to fold and disassemble the equipment during transportation, effectively improving the convenience of carrying and transporting the equipment, and thus improving the ease of use of the equipment.
