DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0024] Refer to Figures 1-4, in an embodiment of the utility model, an early warning device for edge protection in building construction includes two adjacent support columns 1 and a guardrail 2 installed between the support columns 1. On one side of each support column 1 close to the guardrail 2, two mounting seats 3 are fixedly connected. The mounting seats 3 are all of a structure with upper and lower openings, and the bottom of the mounting seat 3 is of an open structure to avoid the closed structure of the mounting seat 3 affecting the emission of the bell sound. On one side of the guardrail 2 close to the support column 1, two connecting plates 4 which are L-shaped structures and are cooperatively connected with the mounting seats 3 are fixedly connected. On one side of each mounting seat 3 close to the guardrail 2, a chute 19 is opened. The connecting plates 4 are all cooperatively slid with the adjacent chutes 19 to ensure the smooth movement operation of the guardrail 2. Among them, early warning components are arranged inside two of the upper mounting seats 3;

[0025] The early warning component includes a sliding plate 5 slidably connected inside the mounting seat 3, two springs 6 symmetrically and fixedly connected to the bottom of the sliding plate 5, two support plates 14 fixedly connected inside the mounting seat 3 and located at the bottom of the springs 6, a rack 7 fixedly connected to the bottom of the sliding plate 5, two fixing plates 8 fixedly connected to the top of the corresponding support plates 14, a rotating shaft 9 rotatably connected inside one of the fixing plates 8, a gear 10 fixedly connected to the outside of the rotating shaft 9 and meshed with the rack 7, a plurality of knocking rods 11 uniformly fixedly connected to one end of the rotating shaft 9, and a knocking bell 12 installed on one side of the fixing plate 8 close to the knocking rod 11. The bottoms of the springs 6 are all fixedly connected to the adjacent support plates 14. The other end of the rotating shaft 9 is fixedly connected to the corresponding fixing plate 8. The knocking rod 11 can contact the outside of the knocking bell 12 through the rotation of the rotating shaft 9. The bottom of the connecting plate 4 contacts the top of the sliding plate 5.

[0026] The guardrail 2 surrounds the construction area to protect and enclose the construction area. When a person wants to climb over the guardrail 2 and enter the construction area, the person exerts pressure on the guardrail 2 to make it move downward. The downward-moving guardrail 2 simultaneously pushes the sliding plate 5 downward through the connecting plate 4. The downward-moving sliding plate 5 can thus realize the rotation of the rotating shaft 9 through the cooperation of the rack 7 and the gear 10. The rotation of the rotating shaft 9 drives the knocking rod 11 at the end to strike the knocking bell 12 to make a sound, sending out an early warning message to remind the climbing person of the dangerous area. At the same time, it can also remind relevant personnel to pay attention and take corresponding safety measures, providing real-time early warning and effectively improving the safety protection level of the edge area to reduce the probability of safety accidents.

[0027] The early warning component further includes two limiting rods 13 slidably connected inside the corresponding support plates 14. The limiting rods 13 are all inserted inside the corresponding springs 6, and the bottoms of the limiting rods 13 are all fixedly connected to a limiting plate in contact with the bottom of the support plate 14. The tops of the limiting rods 13 are all fixedly connected to the sliding plate 5. When the sliding plate 5 moves upward and is reset under the action of the spring 6, the limiting rods 13 and the limiting plate at their bottoms can limit the sliding plate 5.

[0028] A positioning component for positioning the connecting plate 4 is provided at the top of each mounting base 3. The positioning component includes a positioning plate 17 with a U-shaped structure, two guide grooves 15 symmetrically opened on the outer side of the mounting base 3, two sliders 16 slidably connected to the inside of the corresponding guide grooves 15, and a bolt 18 threadedly connected to the inside of the positioning plate 17 and located above the connecting plate 4. Both ends of the positioning plate 17 are fixedly connected to the adjacent sliders 16.

[0029] After the connecting plate 4 is inserted into the mounting base 3, move the positioning plate 17 above the connecting plate 4, and tighten the bolt 18 so that its bottom contacts the top of the connecting plate 4 to position the connecting plate 4, which is beneficial to ensuring the stability of the installation of the guardrail 2. Moreover, the movable connection method facilitates the disassembly and assembly work between the guardrail 2 and the support column 1, making it convenient to use.

[0030] A bottom plate is fixedly connected to the bottom of each support column 1. The larger support area of the bottom plate can support the support column 1 more stably. A plurality of through holes are opened in the bottom plate, which is convenient for fixing the support column 1 to the installation surface. A reflective warning sticker 20 is provided on one side of the guardrail 2 near the bottom to enhance visibility at night or in low-light environments.

[0031] Working principle: The guardrail 2 surrounds the construction area, and can protect and enclose the construction area. When a person attempts to climb over the guardrail 2 and enter the construction area, the person exerts pressure on the guardrail 2 to make it move downward. The downward-moving guardrail 2 simultaneously pushes the sliding plate 5 downward through the connecting plate 4. The downward-moving sliding plate 5 can thus drive the rotation of the rotating shaft 9 through the cooperation of the rack 7 and the gear 10. The rotation of the rotating shaft 9 drives the knocking rod 11 at the end to strike the knocking bell 12 to emit a sound, sending a warning message to remind the climbing person of the dangerous area, and at the same time, it can also remind relevant personnel to pay attention and take corresponding safety measures, providing real-time warning and effectively improving the safety protection level of the edge area to reduce the probability of safety accidents.

[0032] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
