Description

Technical Field

[0001] This utility model relates to the field of safety warning fence technology, and in particular to a safety warning fence for blasting construction. Background Technology

[0002] During blasting, flying rocks, debris, or shock waves may be generated. Enclosures (such as steel plates, blast walls, etc.) can effectively block flying objects and prevent injury to surrounding personnel, vehicles, or buildings. At the same time, enclosures clearly demarcate construction restricted areas to prevent unauthorized personnel from accidentally entering the blasting area and reduce accident risks. Therefore, safety warning enclosures are an indispensable "physical + information" dual barrier in blasting operations. By combining active protection and passive isolation, risks are minimized and life and property and construction compliance are protected.

[0003] Existing warning barriers are all fixed with screws when they are assembled. However, using screws requires workers to install fasteners one by one between the two barriers. There are many bolts to install, which is time-consuming and laborious. Subsequent disassembly is also more troublesome. Moreover, the screws may rust and loosen when used in the external environment, affecting the normal use of the barriers. In addition, it is difficult to adjust the height of the installed barriers according to the actual construction site, which greatly increases their limitations. Utility Model Content

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a safety warning enclosure for blasting construction, including an enclosure panel 1. A limiting groove 4 is provided at one end of the outer side of the enclosure panel 1, and a limiting block 6 is fixedly connected to the other end of the enclosure panel 1. The limiting block 6 and the limiting groove 4 correspond to each other. The two enclosure panels 1 can be quickly merged and installed through the quick correspondence between the limiting block 6 and the limiting groove 4. A connecting shell 19 is fixedly connected to one end of the enclosure panel 1 near the limiting groove 4. A rotating part 2 is rotatably connected to one side of the connecting shell 19. A bevel gear 21 is fixedly connected to the inner end of the rotating part 2.

[0027] A screw 22 is rotatably connected to the other end of the inner side of the connecting shell 19. Two bevel gears 20 are fixedly connected to the screw 22. The bevel gears 20 and 21 mesh with each other. Both ends of the screw 22 are threaded with positioning blocks 10, and all four ends of the positioning blocks 10 are in contact with the inner wall of the enclosure 1. The positioning blocks 10 are restricted by the inner wall of the enclosure 1, so they can move stably under the action of the threaded connection. The interior of the limiting block 6 is provided with a positioning groove 11. The positioning blocks 10 correspond to the positioning groove 11. Rotating the outer rotating part 2 drives the inner bevel gear 21 to rotate, and under the action of meshing, it drives the bevel gears 20 and the screw 22 to rotate. At the same time, under the action of the threaded connection, the positioning blocks 10 can gradually move outward. The positioning blocks 10 extend into the limiting groove 4 and engage with the positioning groove 11, so as to merge and install the two adjacent enclosures 1. The position of the positioning groove 11 is also reserved at the inner end of the limiting groove 4, so as to improve the installation strength between the two enclosures 1.

[0028] A battery box 7 is fixedly connected to one end of the upper part of the fence 1. A camera 8 is installed in the middle of the upper part of the fence 1. An alarm light 9 is installed at the other end of the upper part of the fence 1. Both the camera 8 and the alarm light 9 are electrically connected to the battery box 7. An adhesive position is reserved on the outside of the fence 1 so that warning messages can be pasted on it for warning purposes. At the same time, the battery inside the battery box 7 can power the camera 8 and the alarm light 9. When a suspicious person is found, the alarm light 9 is remotely activated to alert the surrounding staff. A buzzer is installed around the alarm light 9. Together with the alarm light 9, it can achieve a rapid alarm effect, thereby achieving the warning effect.

[0029] Two positioning parts 5 are fixedly connected to the lower end of the fence panel 1. The lower end of the positioning part 5 is threadedly connected to a threaded connector 12. The lower end of the threaded connector 12 is fixedly connected to a fixing post 3. The interior of the fixing post 3 is movably connected to a movable rod 13. The lower end of the movable rod 13 is fixedly connected to an insertion rod 14. The support component is installed on the positioning part 5 through the threaded connector 12. The insertion rod 14 is inserted into the ground to fix the entire fence, ensuring the stable use of the entire fence. When used in different environments, the support component can also be replaced by replacing the insertion rod 14 at the bottom with a support seat, thereby improving the support effect.

[0030] The movable rod 13 has grooves 17 at both ends. A slider 18 is fixedly connected inside the fixed column 3. The slider 18 is slidably connected inside the groove 17. Several screw holes 16 are opened inside the groove 17. Positioning bolts 15 are threadedly connected to the fixed column 3 and the slider 18. The positioning bolts 15 correspond to the screw holes 16. When the height of the support component needs to be adjusted, first turn the two outer positioning bolts 15 so that the positioning bolts 15 leave the inside of the screw holes 16. Under the action of the groove 17 and the slider 18, the length of the insert rod 14 is adjusted, thereby adjusting the height of the entire enclosure. After the adjustment is completed, turning the positioning bolts 15 again can complete the locking effect and improve its stability after adjustment.

[0031] Working principle: During use, the staff selects a suitable location for setup, quickly aligning the limiting blocks 6 and limiting grooves 4 of two adjacent fence panels 1. Then, rotating the outer rotating part 2 drives the inner bevel gear 21 to rotate, and under meshing action, drives the bevel gear 20 and screw 22 to rotate. Simultaneously, under the action of the threaded connection, the positioning block 10 gradually moves outward, and the positioning block 10 extends out to the limiting groove 4 and engages with the positioning groove 11, thereby merging and installing the two adjacent fence panels 1. Secondly, the same method is used for longitudinal installation. Because the limiting blocks 6 and limiting grooves 4 are both square structures, the installation work can be completed even in a longitudinal position. Finally, the support component is installed on the positioning part 5 through the threaded connector 12, and the insertion rod 14 is inserted into the ground to fix the entire fence, ensuring the stable use of the entire fence. At the same time, during use, the battery box 7 can power the camera 8 and the alarm light 9. When a suspicious person is detected, the alarm light 9 will activate to alert the surrounding staff, thereby achieving a warning function.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
