[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides: a foundation pit anti-collapse detection device for building construction, including an anti-displacement base 1, an assembly plate 4, and a protective plate 9; the top of the anti-displacement base 1 is connected to a limiting bracket 3 via an installation bracket 2, the two sides of the assembly plate 4 are connected to the installation bracket 2, and a power control box 7 is installed on the surface of the assembly plate 4 via a bearing plate 6; the protective plate 9 is movably installed on the surface of the limiting bracket 3 via a connecting frame 11, and a protective net frame 12 is detachably connected to the side of the protective plate 9; a fixing plate 14 is connected to the inner surface of the protective plate 9, and the two ends of the fixing plate 14 are slidably connected to the surface of the assembly plate 4 via connecting guide rods 15, and a detection component for warning of foundation pit pressure is provided on the surface of the fixing plate 14.
[0022] It is worth noting that, through the coordinated arrangement of the anti-displacement base 1, assembly plate 4, protective plate 9, protective net frame 12, fixing plate 14 and detection component structure, the pressure of the foundation pit can be detected in real time during use, so as to reinforce the foundation pit in the future, effectively prevent insufficient support strength and collapse, and improve the safety of use.
[0023] Specifically, the connecting frame 11 is symmetrically installed on the inner surface of the protective plate 9, and the connecting frame 11 is slidably installed on the surface of the limiting bracket 3. The surface of the connecting frame 11 is fitted with a top compression spring that cooperates with the limiting bracket 3, and the surface of the anti-displacement base 1 is provided with a reinforcing anchor rod 8.
[0024] Furthermore, the connecting frame 11 is a structure that movably connects the protective plate 9 and the limiting bracket 3. Together with the connection between the bottom and the anti-displacement base 1, it can ensure the protection of the pit wall by the protective plate 9. When the pit is squeezed, it will apply pressure to the weighing sensor 5 in time. The weighing sensor 5 will send the detected data to the display panel 17 for display and alarm in time to ensure the safety of the pit. The reinforcing anchor rod 8 is a structure that reinforces the anti-displacement base 1. The top pressure spring works with the connecting frame 11 to act on the protective plate 9 and improve the structure's protection of the pit wall.
[0025] In addition, connecting slots 10 are provided on both sides of the protective plate 9, and connecting plates 13 are provided at both ends of the protective mesh frame 12. The surface of the connecting plates 13 is movably engaged with the inner wall of the connecting slots 10. The connecting slots 10 cooperate with the connecting plates 13 to assemble the protective mesh frame 12, which facilitates the installation and cleaning of the protective mesh frame 12. The protective mesh frame 12 is elastic and can undergo a certain degree of deformation.
[0026] The detection assembly includes a connecting sleeve 18 connected to the surface of the fixed plate 14, and a load cell 5 embedded in the surface of the assembly plate 4. A sliding post 19 is slidably mounted on the inner wall of the connecting sleeve 18, and a limit baffle 20 is connected to the end of the sliding post 19. A compression spring 21 is fitted onto the surface of the connecting sleeve 18, one end of which is connected to the inner wall of the limit baffle 20. The surface of the limit baffle 20 is pressed against the detection end of the load cell 5.
[0027] The connecting sleeve 18 is used to assemble the sliding column 19, and the limiting baffle 20 limits the compression spring 21 on the surface of the connecting sleeve 18 and the sliding column 19 to prevent the compression spring 21 from falling off. When the protective plate 9 is subjected to force shift, the compression spring 21 transfers the pressure to the detection end of the weighing sensor 5, so that the pit pressure can be observed intuitively through the display panel 17.
[0028] A mounting plate 16 is connected to the end of the connecting guide rod 15. A display panel 17 is mounted on the surface of the mounting plate 16. The load cell 5 and the display panel 17 are electrically connected to the power control box 7. The power control box and the display panel are centrally located to realize the visualization of test data and the integrated management of system power supply, which facilitates real-time monitoring and operation by on-site personnel, and improves the coordination of the test process and the level of intelligent construction management.
[0029] The combination of the anti-displacement base 1 and the reinforcing anchor rod 8 effectively enhances the overall stability of the device, preventing displacement due to external forces or loose foundation during use, and ensuring the accuracy and continuity of the detection data. The protective plate 9 is slidably connected to the limiting bracket 3 through the connecting frame 11 and supplemented by the top pressure spring, enabling the device to adaptively adjust according to the actual situation of the pit sidewall, improving the versatility and practicality of the device. The protective plate 9 and the protective net frame 12 are connected by a detachable slot, which facilitates quick on-site installation, replacement or cleaning, further improving construction efficiency. Through the synergistic action of the weighing sensor 5, the compression spring 21 and the sliding column 19, the device can sensitively detect pressure changes on the pit sidewall and provide real-time alarm feedback through the display panel when the pressure is abnormal, realizing early warning of the risk of pit collapse and effectively preventing construction safety hazards.
[0030] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
