Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, specifically to a trench safety early warning and auxiliary reminder device. Background Technology
[0002] In building construction, trenches are strip-shaped earthwork projects with a bottom width of ≤3 meters and a bottom length exceeding 3 times the bottom width. They are mainly used for the foundation excavation of linear structures such as pipelines, and trench excavation is an important basic task in the construction process.
[0003] Due to factors such as the surrounding environment, soil quality, and groundwater level at the construction site, the liquid level in the trench is prone to sudden rises, which can lead to safety accidents such as sidewall collapse and electrical equipment short circuits. Therefore, liquid level warning is of paramount importance.
[0004] Therefore, we urgently need a trench safety early warning and reminder device. Utility Model Content
[0005] The purpose of this utility model is to provide a trench safety early warning auxiliary reminder device to solve the problem mentioned in the background art, where the liquid level in the trench is prone to sudden rise due to factors such as the surrounding environment of the construction site, soil quality and groundwater level, which may cause safety accidents such as sidewall collapse and electrical equipment short circuit, making liquid level early warning crucial.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a trench safety early warning auxiliary reminder device, including a trench body, an early warning mechanism is provided on the inner side of the trench body, and a protective mechanism is provided on the outer side of the early warning mechanism; The warning mechanism includes a floating plate and a mounting plate. A top rod is fixedly connected to the top of the floating plate, and a laser emitter is fixedly connected to the top of the top rod. A warning frame is fixedly connected to the top of the mounting plate, and a laser receiver is fixedly connected to one end of the warning frame. A positioning plate is fixedly connected to one end of the warning frame, and a sliding block is slidably connected to the inner side of the positioning plate. An alarm is electrically connected to one end of the laser receiver.
[0007] Preferably, the mounting plate is screwed to the top of the groove body, and one end of the top rod passes through the mounting plate and extends to the top of the mounting plate.
[0008] Preferably, there are multiple laser receivers, and the multiple laser receivers are arranged in a linear array.
[0009] Preferably, one end of the sliding block is fixedly connected to one end of the top rod, and one end of the alarm is fixedly connected to one end of the warning frame.
[0010] Preferably, the protective mechanism includes a protective cover, with multiple filters installed on the side of the protective cover and a leakage hole at the bottom of the protective cover.
[0011] Preferably, the protective cover is fixedly connected to the bottom of the mounting plate and covers the outside of the floating plate.
[0012] Preferably, multiple filters are provided, and the multiple filters are arranged in a rectangular array.
[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, this utility model installs an mounting plate above the trench body. When the liquid level in the trench body rises, the float plate moves upward under buoyancy, driving the top rod to rise synchronously. The top rod passes through the mounting plate and drives the sliding block to slide inside the positioning plate, ensuring the vertical and stable movement of the top rod. At the same time, the laser emitter at the top of the top rod moves upward. When the liquid level rises to different heights, the laser emitted by the laser emitter will sequentially align with multiple laser receivers linearly distributed on the warning frame. The aligned laser receivers then transmit electrical signals to the alarm, causing the alarm to issue corresponding warning signals. This achieves precise graded warnings for different liquid levels in the trench body, improving the timeliness and accuracy of the warnings and enhancing safety.
[0014] Secondly, by placing the protective cover outside the float plate, when there is mud, sand, floating debris, etc. in the trench body, the protective cover first forms a physical barrier for the float plate, preventing large impurities from directly contacting the float plate. At the same time, multiple filters distributed in a rectangular array further filter impurities in the water flow, preventing impurities from entangled in the float plate. The leakage holes at the bottom of the protective cover ensure that the accumulated water can smoothly enter the interior of the protective cover, ensuring that the float plate can rise and fall normally with the liquid level. This effectively prevents the float plate from being stuck or interfered with by impurities, ensures the stable operation of the early warning mechanism, and extends the service life of the device.

[0017] 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.
[0018] This utility model provides the following technical solution: Example 1
[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A trench safety early warning auxiliary reminder device includes a trench body 1, an early warning mechanism 2 is provided on the inner side of the trench body 1, and a protective mechanism 3 is provided on the outer side of the early warning mechanism 2; The warning mechanism 2 includes a floating plate 21 and a mounting plate 22. A top rod 23 is fixedly connected to the top of the floating plate 21, and a laser emitter 24 is fixedly connected to the top of the top rod 23. A warning frame 25 is fixedly connected to the top of the mounting plate 22. A laser receiver 26 is fixedly connected to one end of the warning frame 25, and a positioning plate 27 is fixedly connected to one end of the warning frame 25. A sliding block 28 is slidably connected to the inner side of the positioning plate 27. An alarm 29 is electrically connected to one end of the laser receiver 26.
[0020] Mounting plate 22 is screwed to the top of the groove body 1, and one end of top rod 23 passes through mounting plate 22 and extends to the top of mounting plate 22.
[0021] Multiple laser receivers 26 are provided, and the multiple laser receivers 26 are arranged in a linear array.
[0022] One end of the sliding block 28 is fixedly connected to one end of the top rod 23, and one end of the alarm 29 is fixedly connected to one end of the warning frame 25.
[0023] Through the above technical solution, by installing the mounting plate 22 above the trench body 1, when the liquid level in the trench body 1 rises, the float plate 21 first moves upward under the action of buoyancy. The float plate 21 drives the top rod 23 to rise synchronously. The top rod 23 passes through the mounting plate 22 and drives the sliding block 28 to slide inside the positioning plate 27, ensuring that the top rod 23 moves vertically and stably. At the same time, the laser emitter 24 at the top of the top rod 23 moves upward. When the liquid level rises to different heights, the laser emitted by the laser emitter 24 will be aligned sequentially with multiple laser receivers 26 linearly distributed on the warning frame 25. The aligned laser receivers 26 then transmit electrical signals to the alarm 29, causing the alarm 29 to issue a warning signal of the corresponding level. This achieves accurate graded warning for different liquid levels in the trench body 1, improves the timeliness and accuracy of the warning, and enhances the safety effect. Example 2
[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the protective mechanism 3 includes a protective cover 31, a plurality of filters 32 are installed on the side of the protective cover 31, and a leakage hole 33 is provided at the bottom of the protective cover 31.
[0025] The protective cover 31 is fixedly connected to the bottom of the mounting plate 22 and covers the outside of the floating plate 21.
[0026] Multiple filters 32 are provided, and the multiple filters 32 are arranged in a rectangular array.
[0027] Through the above technical solution, by placing the protective cover 31 outside the float 21, when there is mud, sand, floating debris, etc. in the trench body 1, the protective cover 31 first forms a physical barrier for the float 21, preventing large impurities from directly contacting the float 21. At the same time, multiple filter screens 32 distributed in a rectangular array further filter impurities in the water flow, preventing impurities from entangled in the float 21. The leakage holes 33 at the bottom of the protective cover 31 ensure that the accumulated water can smoothly enter the interior of the protective cover 31, ensuring that the float 21 can rise and fall normally with the liquid level. This effectively prevents the float 21 from being stuck or interfered with by impurities, ensures the stable operation of the early warning mechanism 2, and extends the service life of the device.
