Abstract
Description
Technical Field
[0001] This utility model relates to the field of road construction protection technology, and in particular to a warning device for road construction. Background Technology
[0002] During road construction, timely and effective warnings are crucial to ensuring the safety of pedestrians and vehicles. Traditional road construction warning methods mainly rely on warning signs, which are indeed effective in alerting pedestrians and vehicles under good daylight conditions. However, as night falls and ambient light diminishes, the effectiveness of warning signs decreases significantly, especially in areas without streetlights or with insufficient lighting. In these areas, warning signs almost become useless, undoubtedly increasing safety hazards in the construction zone.
[0003] Therefore, existing warning signs are much less visible at night due to insufficient light, making it difficult for pedestrians or vehicles to notice the construction site in time, increasing the probability of accidents. In addition, traditional warning signs are often placed directly on the ground at a low height, making them difficult to attract the attention of pedestrians and drivers, especially at high speeds, where drivers may not be able to spot the signs on the ground in a short time. At the same time, traditional warning signs mostly rely on text or pictures to warn, lacking diverse warning methods such as sound and light, making the warning effect relatively simple and not eye-catching enough.
[0004] In summary, existing warning devices have the following drawbacks: poor nighttime warning effect, low placement of warning signs, and limited warning effectiveness. Utility Model Content
[0005] In view of the above situation and to overcome the shortcomings of the existing technology, this utility model provides a warning device for road construction. This design effectively solves the problems of poor nighttime warning effect, low position of warning signs, and limited warning effect of existing warning devices.
[0006] To achieve the above objectives, the present invention provides the following technical solution: The present invention includes a base, a column fixedly connected to the base, a first support rod fixedly connected to the side of the column, a warning frame fixedly connected to the first support rod, a second support rod fixedly connected above the column, and a warning light installed at the upper end of the second support rod, the height of the warning light being higher than the height of the warning frame;
[0007] The warning frame includes a support, a fixed frame is fixedly connected to the front side of the support, a fixing screw is installed between the fixed frame and the support, a storage slot is opened inside the fixed frame, a slot communicating with the storage slot is opened on the lower side of the fixed frame, a limiting pin is provided at the slot, the limiting pin is slidably connected to the fixed frame, and an observation port is provided on the fixed frame above the limiting pin.
[0008] Preferably, a connecting shaft is provided between the column and the base, the upper end of the connecting shaft is rotatably connected to the column, the lower end of the connecting shaft is fixedly connected to the base, and the base is provided with a fixing hole.
[0009] Preferably, the bracket has an X-shaped structure, with grooves around its perimeter that mate with fixing screws, and a locking block threaded into the inner side of the fixing screws. The fixing frame has a slot for the locking block to slide.
[0010] Preferably, indicator lights are fixedly connected to both sides of the fixed frame.
[0011] Preferably, a third support rod is fixedly connected to both sides of the second support rod, and a solar panel is fixedly connected to the third support rod, with the solar panel facing the back of the fixed frame.
[0012] Preferably, the base is rotatably connected to casters, and the casters are provided with fixed feet around their perimeter, the fixed feet being threadedly connected to the base.
[0013] The outstanding advantages of this invention compared to existing devices are:
[0014] This invention raises the height of the warning frame by using pillars to increase the visibility of the warning. The addition of warning lights to the warning frame reduces the impact of the environment on the warning device in low-visibility environments, thereby improving the warning effect and reducing potential safety hazards.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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. Example 1
[0024] Please see the appendix Figure 1-5 This embodiment provides a warning device for road construction: it includes a base 1, a column 2 fixedly connected to the base 1, a first support rod 3 fixedly connected to the side of the column 2, a warning frame 4 fixedly connected to the first support rod 3, a second support rod 5 fixedly connected above the column 2, and a warning light 6 installed at the upper end of the second support rod 5. The height of the warning light 6 is higher than the height of the warning frame 4.
[0025] The base 1 is a cuboid structure, with the column 2 located above it. The first support rod 3 is vertically connected to the column 2, and the warning frame 4 is placed vertically relative to the first support rod 3. The column 2 can raise the height of the warning frame 4. Compared to warning signs placed on the ground, the warning frame 4 on this device is more conspicuous on the road and can better provide early warning to vehicles and pedestrians. Warning or construction information is set on the front of the warning frame 4 to facilitate understanding of the duration and status of the construction. The warning light 6 directly above the column 2 has four types of lights. The warning light 6 starts to work when the visibility is low, providing an early warning function to passing vehicles and pedestrians to prevent them from rushing into the construction site.
[0026] The warning frame 4 includes a bracket 17, a fixed frame 401 is fixedly connected to the front side of the bracket 17, a fixing screw 402 is installed between the fixed frame 401 and the bracket 17, a storage slot 403 is opened inside the fixed frame 401, a slot 404 communicating with the storage slot 403 is opened on the lower side of the fixed frame, a limiting pin 405 is provided at the slot 404, the limiting pin 405 is slidably connected to the fixed frame 401, and an observation port is provided on the fixed frame 401 above the limiting pin 405.
[0027] The warning frame 4 has a storage slot 403 in the middle of the fixed frame 401. The storage slot 403 is used to place cards with warning information. The cards are placed into the storage slot 403 through the slot 404. After the cards are placed, the lower side is limited by the limiting pin 405. The fixed frame 401 on the front side of the storage slot 403 has an observation port with a transparent plastic plate to facilitate viewing the contents of the storage slot 403. The fixed frame 401 can be used multiple times. In different construction sites, only the contents of the cards inside need to be changed. The fixed frame 401 and the bracket 17 are fixed with fixing screws 402. The two can also be disassembled with fixing screws 402. Different sizes of fixed frames 401 can be replaced in different scenarios. At the same time, the detachable connection between the two also facilitates the transportation and carrying of the device.
[0028] Furthermore, to make the device more convenient to carry, the base 1 can be made of hollow board to reduce the weight of the base 1. Fixing holes 8 are provided at the four corners of the base 1. The fixing holes 8 are fixed by expansion screws, which can fix the base 1 more firmly and also prevent the device from being blown away or moved in strong winds. The device can still serve as a warning in its original position in strong winds.
[0029] The connecting shaft 7 is located between the base 1 and the column 2. A locking pin is provided between the connecting shaft 7 and the column 2. After the locking pin is removed, the connecting shaft 7 and the column 2 can rotate relative to each other. After the base 1 is installed, the direction of the warning frame 4 is ensured to be opposite to the construction position.
[0030] The bracket 17 has an X-shaped structure, and each of the four corners of the bracket 17 has a sliding groove 9. The locking block 10 inside the fixing screw 402 is locked in the slot 11 of the fixing frame 401. The fixing screw 402 drives the locking block 10 to move outward along the sliding groove 9, locking the locking block 10 in the outermost position of the slot 11. Then, by rotating the fixing screw 402, the fixing screw 402 pulls the locking block 10 to move towards the bracket 17, thereby locking the fixing frame 401 and the bracket 17 together.
[0031] The indicator lights 12 on both sides of the fixed frame 401 are arrow indicator lights 12, which indicate that the road is closed and provide guidance on the direction of travel for vehicles and pedestrians, so as to avoid congestion in front of the construction site.
[0032] There are two second support poles 5, and solar panels 14 are installed on both third support poles 13. The solar panels 14 can convert light energy into electrical energy for storage. The stored electrical energy powers the warning light 6 at night, thereby reducing the need for external power supply and internal power supply, and facilitating the operation of the device. The solar panels 14 face the back of the warning frame 4, which can prevent sunlight from reflecting in front of the warning frame 4 and prevent light from affecting the vision of oncoming vehicles and pedestrians. Example 2
[0033] The structure is the same as that of the above embodiments, such as Figure 6 As shown, the specific difference in this embodiment is that: a caster 15 is rotatably connected to the base 1, and fixed feet 16 are provided around the caster 15, and the fixed feet 16 are threadedly connected to the base 1.
[0034] The fixed feet 16 are threaded around the base 1. Rotating the fixed feet 16 can adjust the height of the fixed bracket 17 off the ground. When the fixed feet 16 are close to the bottom of the base 1, the device can be pushed to roll forward on the ground by the casters 15, reducing the friction between the device and the ground. When it is necessary to fix it, the casters 15 can be raised off the ground by the fixed feet 16. The four fixed feet 16 are controlled independently, which can also provide good stable support for the device on uneven roads.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
