[0019] 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.

[0020] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a foundation pit protection device, including a base 1, which is integrally welded from Q235 low-carbon steel plate with a thickness of 8mm. The bottom is laser-cut to create a flat contact surface, ensuring a tight fit with the foundation and reducing the risk of settlement. It can also withstand minor impacts during construction without deformation. A guardrail 2 is installed on the base 1, made of high-strength aluminum alloy tubing and detachably connected to the base 1 by bolts. The guardrail 2 prevents personnel and debris from falling while maintaining a clear view, allowing construction personnel to observe the interior of the foundation pit. The surface is coated with a light gray environmentally friendly powder coating using an electrostatic spraying process, effectively resisting corrosion from cement slurry, silt, and other corrosive substances during foundation pit construction, maintaining a clean appearance. The base 1 is equipped with reflective strips 12, which use microprism structure reflective film, providing a visibility distance of over 100m under nighttime lighting. The reflective strips are adhered with 3M strong adhesive and secured with rivets at the edges to prevent detachment due to long-term wind and rain, ensuring a lifespan of over 5 years. A solar panel 3, using monocrystalline silicon solar panels, is installed on the top of the guardrail 2, fixed to the guardrail 2 with an aluminum alloy bracket. This allows for adjustment based on the sunlight angle at the construction site, improving power generation efficiency. A warning light 4, using LED strobe lights, is installed on one side of the solar panel 3. It features red and yellow dual-color switching and a nighttime visibility distance of up to 500m. The warning light 4's casing is made of PC material, capable of withstanding impacts from gravel during construction. A buzzer 20 is installed below the warning light 4. The buzzer 20 has an adjustable volume, with a default warning volume of 85dB, ensuring clear alarm signals even in noisy construction environments. The buzzer 20 features a waterproof casing to prevent rainwater from entering and causing short circuits. It also includes a dustproof mesh to prevent mud and sand from clogging the sound-emitting holes. The solar panel 3 is equipped with a 12V / 30Ah lithium battery, housed in a waterproof box inside the base 1. It also features an MPPT charging controller to intelligently adjust the charging current, preventing overcharging and over-discharging of the lithium battery and extending its lifespan. Under an average of 4 hours of sunlight per day, the lithium battery can store enough energy to power the warning light 4, buzzer 20, LED light 18, and other components continuously for over 72 hours, completely eliminating reliance on mains power. The system also includes: a movable component 5 mounted on the base 1 for easy movement of the base 1 and guardrail 2; and an auxiliary component 6 mounted on the base 1 for temporary use.

[0021] Furthermore, the movable component 5 includes a groove 10 formed on the base 1. The groove 10 is reinforced with welded steel plates, forming a cavity for mounting the cylinder 7. The cylinder 7 is installed inside the groove 10. The cylinder 7 is a small pneumatic cylinder, which can easily move the base 1 and guardrail 2 as a whole. The cylinder body is chrome-plated, achieving an IP65 rust-proof rating, suitable for damp construction environments in foundation pits. It is also equipped with a hydraulic lock, which can lock the cylinder 7 at any extended position to prevent sudden pressure drops from causing the wheels to sink. A push plate 8 is installed at the output end of the cylinder 7. The push plate 8 is made of Q235 steel plate, and a caster 9 is installed at the bottom of the push plate 8. The caster 9 has a built-in braking function. The caster 9 is a heavy-duty industrial caster made of high-elasticity polyurethane, possessing good wear resistance and shock absorption, effectively preventing scratches on the foundation surface. The caster 9 has a dual-brake function, ensuring stable fixation after the protective device is moved into position, preventing slippage. The brake pedal features an anti-slip textured design for easy operation by construction personnel.

[0022] Meanwhile, a slot 13 is provided on the push plate 8, and an elastic pad 21 is installed inside the slot 13. The elastic pad 21 is made of EPDM rubber with a thickness of 5mm and is attached to the bottom of the slot 13. It has good elasticity and wear resistance. When the locking block 16 is inserted into the slot 13, the elastic pad 21 can buffer the impact force and fill the gap to prevent the locking block 16 from loosening. An electromagnetic suction 14 is installed inside the slot 13. The surface of the electromagnetic suction 14 is covered with an epoxy resin coating, which has insulation and rust prevention functions. After being energized, it can firmly attract the locking block 16, further improving the installation stability of the temporary pedal 15.

[0023] The movable component 5 enables rapid movement and position adjustment of the protective device without disassembling the module, thus improving the ease of operation and management.

[0024] This utility model is equipped with a movable component 5. By installing a cylinder 7 and universal wheels 9 on the base 1, it is easy to move the guardrail 2. During the construction of the foundation pit, it is necessary to adjust the position of the protection. When the excavation range of the foundation pit changes or the local construction area is changed, there is no need to disassemble the module. A single person can push the protection unit to move. At the same time, when the foundation settles slightly, the horizontal height of the protection unit can be adjusted by extending one wheel, so as to prevent the guardrail from tilting due to settlement. It can be restored to a horizontal state without disassembly and reassembly. It is adapted to the common problem of uneven settlement of the foundation during foundation pit construction, has strong adaptability, and facilitates construction.

[0025] Example 2: This is a further description of Example 1: Please refer to... Figure 1-5The auxiliary component 6 includes a temporary pedal 15 detachably mounted on the push plate 8. The temporary pedal 15 is made of aluminum alloy honeycomb panel, with the panel material being 5052 aluminum alloy and the core layer being an aluminum honeycomb structure. The surface of the temporary pedal 15 is sandblasted and then coated with a polytetrafluoroethylene wear-resistant coating, which can effectively prevent construction workers from slipping even in humid environments. Symmetrically mounted clips 16 are installed on the temporary pedal 15, integrally molded with the temporary pedal 15 through injection molding, capable of bearing the entire weight of the temporary pedal 15 without falling off. The surface of the clips 16 is frosted to enhance friction with the elastic pad 21, further improving installation stability. A protrusion 17 is fixedly connected to the clip 16, secured to the top of the clip 16 with bolts, facilitating the upward pulling and removal of the temporary pedal 15 by construction workers. The sides of the protrusion 17 are designed with an arc shape to prevent snagging on clothing during use. The temporary pedal 15 can be quickly removed by pulling the protrusion 17 upward.

[0026] Furthermore, the size of the locking block 16 corresponds to the locking slot 13, and the electromagnetic suction 14 attracts the locking block 16 when energized, which facilitates the improvement of the stability of the temporary pedal 15 during installation.

[0027] It should be noted that an LED light 18 is installed under the temporary pedal 15. The housing of the LED light 18 is made of PC material with an IP65 waterproof rating to prevent rainwater from entering and causing damage. A pressure sensor 19 is installed on one side of the LED light 18. The LED light 18 is activated at night to improve the safety of the auxiliary component 6. The pressure sensor 19 is used to sense the pressure above the temporary pedal 15 and is connected to the control panel 11 via a wire. The sensor surface is covered with a stainless steel protective film, which has good pressure resistance and corrosion resistance. It can monitor the load-bearing weight of the temporary pedal 15 in real time to prevent multiple people from stepping on it simultaneously and causing overloading, thus improving the safety of the equipment.

[0028] A control panel 11 is installed on the base 1. The solar panel 3, warning light 4, cylinder 7, electromagnetic suction 14, LED light 18 and buzzer 20 are all electrically connected to the control panel 11.

[0029] When used at night, construction workers can turn on the LED light 18 through the control panel 11. The light illuminates the surface and area below the temporary step 15, preventing personnel from stepping out of place due to dim lighting. At the same time, the LED light 18 is linked with the warning light 4. When the warning light 4 is in the warning state, the LED light 18 will switch to flashing red light to remind personnel to pay attention to safety.

[0030] The working principle of this device is as follows: First, when the position of the protective device needs to be adjusted, the worker sends a "wheel extension" command through the control panel 11. The cylinder 7 is then energized, and its output pushes the push plate 8 downwards until the caster wheel 9 contacts the ground and lifts the base 1. At this point, the cylinder 7 can be deactivated and the hydraulic lock engaged. A single worker can move the protective device at a speed of up to 0.5 m / s, completing a 10-meter adjustment within 10 minutes. After positioning, the worker steps on the brake pedal of the caster wheel 9 to lock the wheels, and then uses the control panel 11 to retract the cylinder 7, bringing the base 1 to contact the ground, thus completing the position adjustment. Secondly, when slight settlement of the foundation causes the protective device to tilt, construction workers can use the control panel 11 to individually extend the cylinder 7 on the settled side, adjust the extension height of the caster 9 on that side until the guardrail 2 returns to a horizontal state, and then lock the cylinder 7 and keep the caster 9 in a braking state. This process does not require disassembling the protective device and can be completed by a single person within 5 minutes, effectively avoiding safety hazards caused by the tilt of the guardrail and adapting to the common problem of uneven settlement of the foundation during foundation pit construction. Finally, during installation, the worker aligns the locking block 16 of the temporary pedal 15 with the slot 13 of the push plate 8 and presses it down until the locking block 16 is fully inserted. Then, the electromagnetic suction 14 is energized via the control panel 11, generating a magnetic force to attract the locking block 16, completing the installation. For disassembly, the worker disconnects the power to the electromagnetic suction 14 via the control panel 11, the magnetic force disappears, and then pulls the protrusion 17 upwards to remove the locking block 16 from the slot 13, completing the disassembly of the temporary pedal 15. Compared to traditional bolt-connected pedals, disassembly efficiency is increased by over 90%, and no tools are required, making operation convenient.
