Description

Technical Field

[0001] This utility model relates to the field of warning technology for environmental protection engineering in transportation, specifically a warning device for environmental protection engineering in transportation. Background Technology

[0002] Construction work is a special accounting subject for construction and installation companies to collect and calculate project costs. It refers to the activities of building, expanding, or renovating a construction project in accordance with the requirements of the construction project design documents. Construction work includes four sub-items: labor costs, material costs, machinery costs, and other direct costs.

[0003] To prevent pedestrians from being injured during environmental protection construction, warning signs need to be placed near the construction site. The components of existing warning signs are generally welded and fixed, which results in a large space occupied during transportation and storage, affecting transportation and storage. In addition, a small number of warning signs are modular structures, so they need to be assembled before placement. However, existing warning signs are inconvenient for users to assemble, wasting a lot of users' time and reducing the practicality of the warning signs.

[0004] As disclosed in Chinese Patent CN219080134U, an environmental protection engineering construction warning device can be assembled and disassembled to facilitate its storage and transportation. The warning sign is suspended and fixed on the support rod by screwing the screw rod with the screw hole and fixing the vertical rod with the screw rod. The base and support rod are movably fixed by fixing the vertical plate and support rod with the locking rod, thereby achieving the purpose of facilitating the assembly and disassembly of the warning sign, base and support rod.

[0005] However, the warning sign lacks lighting, making it impossible to see the warning messages at night.

[0006] Therefore, we urgently need to provide a warning device with lighting function for transportation environmental protection projects. Utility Model Content

[0007] The purpose of this utility model is to provide a warning device for environmental protection engineering in transportation, so as to solve the problem mentioned in the background art that the warning signs do not have a lighting structure, thus making it impossible to see the warning statements on the warning signs at night.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a warning device for environmental protection engineering in transportation, comprising a warning sign and a support rod, wherein the support rod is disposed at the lower end of the warning sign, and a base is connected to the lower end of the support rod; a warning mechanism is connected to the outer ends of the warning sign and the support rod; the warning mechanism comprises a lighting unit and a disassembly unit, wherein the lighting unit is disposed at the upper end of the warning sign, and the disassembly unit is disposed at the outer end of the warning sign.

[0009] The lighting unit includes a connecting rod, a round shaft, a rotating block, a lighting lamp, a first threaded rod, and a rotating handle. The connecting rod is fixedly connected to the upper side of the warning sign at equal intervals. The round shaft is connected to the front end of the connecting rod. The rotating block is connected to the outer end of the round shaft. The lighting lamp is fixedly connected to the lower end of the rotating block. The first threaded rod is connected to the right side of the inner front end of the connecting rod. The rotating handle is fixedly connected to the right end of the first threaded rod.

[0010] A further improvement is that the front end of the connecting rod has a groove, the center of the rotating block has a rotating hole, the left and right sides of the circular shaft are fixedly connected to the center of the front ends of the left and right sides of the groove, the outer side of the circular shaft is rotatably connected to the inner side of the rotating hole, and the left and right sides of the rotating block are slidably connected to the left and right ends of the inner side of the groove. This allows the rotating block to rotate around the circular shaft within the groove.

[0011] A further improvement is that a threaded hole is provided inside the connecting rod at the upper right end of the groove. The outer side of the first threaded rod is threaded to the inner side of the threaded hole, and the left end of the first threaded rod abuts against the right side of the rotating block. Thus, after the rotating block rotates around the circular axis and drives the lamp to rotate to a suitable lighting angle, rotating the handle causes the first threaded rod to rotate within the threaded hole and move to the left until the left end of the first threaded rod contacts the right side of the rotating block, thereby fixing the rotating block in the groove and completing the adjustment of the lighting angle of the lamp.

[0012] A further improvement is that the disassembly unit includes a concave fixing component, a spring, a plug rod, a connecting plate, a second threaded rod, and a cylinder. The concave fixing component is fixedly connected to the upper side of the support rod, the spring is connected to the middle position of the lower end inside the warning sign, the plug rod is fixedly connected to the front end of the spring, the connecting plate is fixedly connected to the lower side of the support rod, the second threaded rod is fixedly connected to the upper left and right ends of the support rod, and the cylinder is connected to the outer side of the second threaded rod.

[0013] A further improvement is that a circular groove is formed at the front of the lower center of the warning sign, and an insertion hole is formed at the center of the front end of the concave fixing member. The rear end of the spring is fixedly connected to the inner rear end of the circular groove, the outer side of the insertion rod is slidably connected to the inner side of the circular groove, the middle position of the lower outer side of the warning sign is slidably connected to the inner side of the concave fixing member, and the outer side of the insertion rod is inserted into the inner side of the insertion hole. Therefore, by pressing the insertion rod into the circular groove, the warning sign can be removed from the concave fixing member.

[0014] A further improvement is that a through hole is provided at the middle of the left and right ends of the connecting plate, and an internal thread is provided on the inner side of the cylinder. The outer side of the second threaded rod is slidably connected to the inner side of the through hole, and the outer side of the second threaded rod is threadedly connected to the inner side of the cylinder. The lower side of the cylinder abuts against the upper left and right ends of the connecting plate. Thus, by rotating the cylinder to remove it from the outer side of the second threaded rod, the connecting plate can be removed from the outer end of the second threaded rod at the upper end of the base, thereby separating the support rod from the base.

[0015] A further improvement is that rectangular sleeves are symmetrically fixedly connected to the upper ends of the left and right sides of the warning sign. A fixing rod is slidably connected to the inner side of each rectangular sleeve, and a canopy is fixedly connected to the upper end of each fixing rod. Thus, by sliding the lower end of the fixing rod to the inner side of the rectangular sleeve, the canopy can be fixed to the upper end of the warning sign, providing rain protection.

[0016] In summary, this application discloses a warning device for environmental protection engineering in transportation.

[0017] In this technical solution, after the rotating block rotates around the circular axis to drive the lighting lamp to a suitable lighting angle, the rotating handle is then rotated to drive the first threaded rod to rotate within the threaded hole and move to the left until the left end of the first threaded rod contacts the right side of the rotating block. This fixes the rotating block in the groove, thus completing the adjustment of the lighting angle of the lighting lamp. This allows the lighting lamp to be adjusted according to the position to be illuminated on the warning sign.

[0018] Furthermore, by pressing the rear insert rod into the circular groove, the warning sign can be removed from the concave fixing part. After rotating the cylinder to remove it from the outside of the second threaded rod, the connecting plate can be removed from the outer end of the second threaded rod at the top of the base, thus separating the support rod from the base. This makes the disassembly of the warning device very convenient, reduces assembly time, and increases practicality. Attached Figure Description

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] Example 1:

[0028] A warning device for environmental protection engineering in transportation includes a warning sign 1 and a support rod 2. The support rod 2 is located at the lower end of the warning sign 1, and a base 3 is connected to the lower end of the support rod 2. A warning mechanism is connected to the outer ends of the warning sign 1 and the support rod 2. The warning mechanism includes a lighting unit and a disassembly unit. The lighting unit is located at the upper end of the warning sign 1, and the disassembly unit is located at the outer end of the warning sign 1.

[0029] The lighting unit includes a connecting rod 401, a round shaft 402, a rotating block 403, a lighting lamp 404, a first threaded rod 405, and a rotating handle 406. The connecting rod 401 is fixedly connected to the upper side of the warning sign 1 at equal intervals. The round shaft 402 is connected to the front end of the connecting rod 401, and the rotating block 403 is connected to the outer end of the round shaft 402. A groove is formed at the front end of the connecting rod 401, and a rotating hole is formed in the middle of the interior of the rotating block 403. The left and right sides of the round shaft 402 are fixedly connected to the middle of the front ends of the left and right sides of the groove, and the outer side of the round shaft 402 is rotatably connected to the inner side of the rotating hole. The left and right sides of the rotating block 403 are slidably connected to the left and right ends of the inner side of the groove. This allows the rotating block 403 to rotate around the round shaft 402 within the groove.

[0030] The lighting lamp 404 is fixedly connected to the lower end of the rotating block 403. The first threaded rod 405 is connected to the right side of the inner front end of the connecting rod 401, and the rotating handle 406 is fixedly connected to the right end of the first threaded rod 405. A threaded hole is provided inside the connecting rod 401 at the upper front right end of the groove. The outer side of the first threaded rod 405 is threadedly connected to the inner side of the threaded hole, and the left end of the first threaded rod 405 abuts against the right side of the rotating block 403. Thus, after the rotating block 403 rotates around the circular shaft 402 and drives the lighting lamp 404 to rotate to a suitable lighting angle, the rotating handle 406 is then rotated to drive the first threaded rod 405 to rotate within the threaded hole while moving to the left until the left end of the first threaded rod 405 contacts the right side of the rotating block 403, thereby fixing the rotating block 403 in the groove and completing the adjustment of the lighting angle of the lighting lamp 404.

[0031] Example 2:

[0032] Based on Embodiment 1: The disassembly unit includes a concave fixing component 501, a spring 502, a plug rod 503, a connecting plate 504, a second threaded rod 505, and a cylinder 506. The concave fixing component 501 is fixedly connected to the upper side of the support rod 2. The spring 502 is connected to the middle position of the lower inner end of the warning sign 1. The plug rod 503 is fixedly connected to the front end of the spring 502. A circular groove is formed in front of the middle position of the lower inner end of the warning sign 1. An insertion hole is formed in the middle position of the front end of the concave fixing component 501. The rear end of the spring 502 is fixedly connected to the rear end of the inner side of the circular groove. The outer side of the plug rod 503 is slidably connected to the inner side of the circular groove. The middle position of the lower outer side of the warning sign 1 is slidably connected to the inner side of the concave fixing component 501. The outer side of the plug rod 503 is inserted into the inner side of the insertion hole. Thus, by pressing the plug rod 503 into the circular groove, the warning sign 1 can be removed from the concave fixing component 501.

[0033] A connecting plate 504 is fixedly connected to the lower side of the support rod 2, and a second threaded rod 505 is fixedly connected to the upper left and right ends of the support rod 2. A cylinder 506 is connected to the outer side of the second threaded rod 505. A through hole is provided at the middle of the left and right ends inside the connecting plate 504. An internal thread is provided on the inner side of the cylinder 506. The outer side of the second threaded rod 505 is slidably connected to the inner side of the through hole, and the outer side of the second threaded rod 505 is threadedly connected to the inner side of the cylinder 506. The lower side of the cylinder 506 abuts against the upper left and right ends of the connecting plate 504. By rotating the cylinder 506 to remove it from the outer side of the second threaded rod 505, the connecting plate 504 can be removed from the outer end of the second threaded rod 505 at the upper end of the base 3, thus separating the support rod 2 from the base 3.

[0034] Example 3:

A fixing rod 7 is slidably connected to the inner side of the rectangular sleeve 6, and a canopy 8 is fixedly connected to the upper end of the fixing rod 7. Thus, by sliding the lower end of the fixing rod 7 to the inner side of the rectangular sleeve 6, the canopy 8 can be fixed to the upper end of the warning sign 1, providing rain protection for the warning sign 1.

[0036] Working principle: First, place the connecting plate 504 at the lower end of the support rod 2 on the base 3. At the same time, the second threaded rod 505 passes through the through hole. Then, thread the cylinder 506 to the outside of the second threaded rod 505 until it contacts the upper left and right ends of the connecting plate 504. Fix the connecting plate 504 to the upper end of the base 3. Then, press the insert rod 503 to press it into the inside of the circular groove. Then, slide the lower middle position of the warning sign 1 to the inside of the concave fixing part 501. Then, the spring 502 rebounds and pushes the insert rod 503 forward, pushing the front end of the insert rod 503 into the insertion hole at the front end of the concave fixing part 501. Fix the warning sign 1 to the concave fixing part 501, completing the assembly of the warning device.
