[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way serves as any limitation on the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 4 As shown, an embodiment of the present utility model provides a slope over-limit alarm device, including an alarm device body, which includes a shell structure and a dynamic tilt sensor 12 and a single-chip microcomputer 13 arranged in the shell structure, the dynamic tilt sensor 12 and the single-chip microcomputer 13 are electrically connected, and the dynamic tilt sensor 12 is used to detect the tilt angle; an adjustment part, the adjustment part includes a mounting foot 33, a length adjustment structure and a transfer structure connected in sequence, the mounting foot 33 is used to be connected to the cab of the bulldozer, the length adjustment structure can adjust the distance between the mounting foot 33 and the transfer structure, and the transfer structure is movably connected to the upper side of the shell structure; there are multiple adjustment parts, and the multiple adjustment parts are spaced apart on the upper side of the shell structure.

[0039] In this solution, after the slope excess alarm device is installed at different concave and convex positions of the cab, the distance between the mounting legs 33 and the alarm device body can be adjusted through the length adjustment structure, so that the alarm device body can be adjusted to be horizontal, thereby ensuring the horizontality of the dynamic inclination sensor 12 during initial installation, thereby ensuring the accuracy of detection during use.

[0040] like Figure 3 As shown, the length adjustment structure includes a sleeve 31 and a threaded rod 32. Sleeve 31 and threaded rod 32 are threadedly connected. The upper end of threaded rod 32 is connected to mounting foot 33, and the lower end of sleeve 31 is rotatably connected to the adapter structure. This structure not only facilitates adjustment but also maintains good stability during long-term use. It is suitable for bulldozers operating continuously for long periods of time, such as in large-scale earthwork projects and road construction projects.

[0041] The outer circumference of the sleeve 31 is provided with a rubber pad, which increases friction and facilitates the rotation of the sleeve 31 during use.

[0042] like Figure 2 As shown, the excessive slope alarm device also includes a level bead 2 and a level ruler 21, mounted on different outer side walls of the housing structure. The inclusion of these two elements allows the operator to intuitively determine whether the device is level, improving installation accuracy and making it suitable for applications requiring high-precision work, such as precision construction and bridge building.

[0043] Specifically, the adapter structure is a ball bearing 3. The design of the ball bearing 3 enables free rotation in multiple directions during operation, avoiding jamming during adjustment, adapting to various angle changes of the cab, improving the adaptability and flexibility of the device, and being suitable for bulldozers with variable cab structures.

[0044] like Figure 3As shown, the mounting foot 33 has a mounting hole for inserting a fastener. This design makes the slope overrun alarm device more securely mounted, preventing it from loosening during operation, and is suitable for bulldozers operating in extreme weather conditions, such as rain, snow, windy and sandy environments.

[0045] The housing structure comprises an installation box 1 and a cover 11. The lower portion of the installation box 1 has an opening, which is connected to the cover 11 and seals the opening. A dynamic tilt sensor 12 and a single-chip microcomputer 13 are mounted above the cover 11. This structural design not only protects the internal sensors and single-chip microcomputer 13 but also facilitates maintenance and inspection, making it suitable for bulldozers operating in harsh environments, such as those with high temperature, high humidity, and high dust levels.

[0046] Furthermore, the main body of the alarm device also includes a battery 14, which is installed above the box cover 11. Battery 14 provides power to the single-chip microcomputer 13 and the dynamic tilt sensor 12. The design of the built-in battery 14 eliminates the need for an external power source for the alarm device, improving the device's portability and independence, making it suitable for bulldozer operations in remote areas or environments without power supply.

[0047] In this embodiment, the alarm system also includes a warning light 15 and a speaker 16, mounted below the cover 11. When the tilt angle detected by the dynamic tilt sensor 12 exceeds a set value, the warning light 15 and speaker 16 sound an alarm. This design provides a timely reminder to the operator to avoid rollover accidents caused by improper operation. It is suitable for bulldozers operating in environments with poor visibility or high noise levels, such as nighttime operations and busy construction sites.

[0048] Furthermore, the main body of the alarm device includes a display screen 17, which is mounted on the outer wall of the housing structure and electrically connected to the single-chip microcomputer 13. Display screen 17 is used to display the detection results of the dynamic tilt sensor 12. The addition of display screen 17 allows the operator to monitor the tilt angle of the bulldozer in real time, improving the safety and efficiency of the operation. It is suitable for operating environments that require real-time monitoring of the tilt angle, such as during slope operations and excavation operations.

[0049] Among them, two level beads 2 are symmetrically arranged about the center line of the installation box 1. The two level beads 2 can facilitate the user to observe the horizontal condition of the device. The box cover 11 and the installation box 1 are fixed by bolts, which can make the installation of the box cover 11 and the installation box 1 more firm and reliable.

[0050] The working principle of this solution is: when using the device, use bolts and mounting feet 33 to install the device in the bulldozer cab at a position that does not affect driving, rotate the sleeve 31 to adjust the extension and contraction of the threaded rod 32, and level the installation box 1 by observing the position of the bubble in the level bead 2 and the level ruler 21. This can ensure the horizontality of the dynamic inclination sensor 12 and facilitate the detection of the angle by the dynamic inclination sensor 12. When the device is in use, the dynamic inclination sensor 12 detects the angle of the bulldozer, and the display screen 17 displays the inclination data in real time. When the slope exceeds the limit, the single-chip microcomputer 13 controls the warning light 15 to flash, and the speaker 16 broadcasts the over-limit warning to facilitate the driver to make timely adjustments. The device is powered by a battery 14 to ensure the endurance of the device.

[0051] The slope overlimit alarm device provided in this solution monitors the bulldozer's inclination angle in real time through a dynamic inclination sensor 12, and processes and judges the data through a single-chip microcomputer 13. Once the detected inclination angle exceeds a preset safety threshold, an alarm is immediately issued through a warning light 15 and a speaker 16 to remind the operator to take timely measures to avoid accidents caused by excessive slopes.

[0052] In addition, the design of the length adjustment structure and the adapter structure enables the alarm device to flexibly adapt to the cabs of different models of bulldozers, improving the versatility of the device and the ease of installation. The provision of rubber pads increases friction, facilitating adjustment operations. The addition of the display screen 17 allows the operator to intuitively understand the current tilt angle, improving work safety and efficiency. Overall, this device effectively improves the safety of bulldozers operating on complex terrain, reduces the risk of accidents, and has significant practical value and application prospects.

[0053] In practical applications, the device can also be linked to the bulldozer's control system. Once an excessive slope is detected, it automatically triggers safety mechanisms, such as limiting the bulldozer's speed or direction, further enhancing safety. Furthermore, through data recording and analysis, the device can provide a reference for bulldozer maintenance and operation, helping operators and maintenance personnel better understand the equipment's operating status, prevent potential failures and risks, and improve equipment lifespan and operating efficiency.
