[0002] Municipal engineering refers to urban public utility projects such as urban roads, bridges, water supply and drainage, sewage treatment, urban flood control, gardens, road greening, street lights and environmental sanitation, including: road traffic projects, river and lake water system projects and underground pipeline projects. In order to ensure the normal use of municipal engineering, municipal engineering needs to be inspected and maintained regularly. When inspecting and maintaining municipal engineering, roadblocks need to be placed nearby to remind and warn pedestrians.

[0003] Chinese patent publication number CN114908693A discloses a municipal engineering road warning device, comprising a traffic cone; a light source generator configured at the tip of the traffic cone; the light source generator comprises a mounting ring sleeved on the outer surface of the traffic cone, the mounting ring being mounted with a plurality of mounting rods evenly distributed around the circumference, each of which is secured with an LED light.

[0004] The aforementioned patent utilizes a light-generating device to manually place traffic cones near municipal engineering inspection and maintenance sites, illuminating them at night to serve as a warning.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1: A warning device for municipal engineering, such as Figures 1-10 As shown, it includes a sliding plate 1, a rotating rod 2, a reflective cloth 22, a gear 3, a threaded rod 4, a warning light 5, a rotating plate 6, a telescopic rod 7, a convex plate 8 and a rack 9. A sliding groove 21 is opened at the front of the sliding plate 1, the middle part of the sliding plate 1 is rotatably connected to the rotating rod 2, the lower part of the rotating rod 2 is fixed with a gear 3, the rotating rod 2 is threadedly connected with the threaded rod 4, a reflective cloth 22 is provided between the threaded rod 4 and the sliding plate 1, a warning light 5 is installed on the upper part of the threaded rod 4, the lower part of the rotating rod 2 is rotatably connected to the rotating plate 6, telescopic rods 7 are provided between the rotating plate 6 and the two ends of the sliding plate 1 and the threaded rod 4, the front of the front sliding plate 1 is slidably connected to the moving plate 127, the rear of the sliding plate 1 is fixed with a convex plate 8, the convex plate 8 slides in the adjacent sliding groove 21, the left side of the rear of the sliding plate 1 is fixed with a rack 9, and the movement of the gear 3 on the rear rotating rod 2 will engage with the rack 9 of the front sliding plate 1.

[0029] First, pull the sliding plate 1 on one side. Pulling out the sliding plate 1 will pull out the telescopic rod 7 and the rotating rod 2 on it together. During the pulling out process of the sliding plate 1, the gear 1 will mesh with the rack 1 9, thereby causing the gear 3 to rotate. The rotation of the gear 1 3 will drive the rotating rod 2 to rotate, and the rotation of the rotating rod 2 will drive the rotating plate 6 to rotate together. Since the telescopic rod 7 is connected between the sliding plate 1 and the threaded rod 4, the rotating rod 2 rotates to cause the threaded rod 4 to move upward, and the upward movement of the threaded rod 4 will cause the telescopic rod 7 to extend. Then, the reflective cloth 22 is placed on the telescopic rod 7. Through the action of the reflective cloth 22, the sliding plates 1 are pulled out in turn in the same way, so that the municipal engineering operation area can be warned. If municipal engineering operations are carried out at night, the warning light 5 can be controlled, so that the device can also play a good warning role at night.

[0030] When the municipal engineering work is completed, the reflective cloth 22 is put away, and then the sliding plate 1 is pulled back. At this time, the gear 3 and the rack 9 will contact each other again, thereby reversing the gear 3, so that the rotating plate 6 is reversed and restored to its original position. The reversal of the gear 3 will also make the threaded rod 4 move downward, and the downward movement of the threaded rod 4 will cause the telescopic rod 7 to contract, so that the sliding plate 1 can be completely put away, thereby eliminating the need for manual labor to frequently place and put away the road cones one by one, thereby reducing labor intensity, saving time, and improving the efficiency of municipal engineering work.

[0031] Example 2: Based on Example 1, Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 9 and Figure 10 As shown, it also includes a fixing mechanism, which includes a limit rod 101, a compression spring 102, a fixing plate 103, a return spring 104 and a sliding rod 105. The left part of the sliding plate 1 is slidably connected to the limit rod 101. The lower part of the limit rod 101 is conical. When the limit rod 101 moves downward, it will contact the ground, thereby better fixing the device. The right part of the front sliding plate 1 is also slidably connected to the limit rod 101. A compression spring 102 is fixed between the limit rod 101 and the adjacent sliding plate 1. The limit rod 101 The top is fixed with a fixed plate 103, and the left part of the sliding plate 1 is slidably connected to a sliding rod 105. The fixed plate 103 and the sliding rod 105 are both inclined on the side close to each other. A return spring 104 is fixed between the sliding rod 105 and the adjacent sliding plate 1. When the fixed plate 103 moves downward, it will squeeze the sliding rod 105, and the return spring 104 is compressed. When the fixed plate 103 continues to move downward, it will separate from the sliding rod 105, and the return spring 104 will recover. The sliding rod 105 then moves to the left to return to its original position, thereby limiting the fixed plate 103.

[0032] like Figure 6 and Figure 7 As shown, it also includes an extrusion block 106 and a coil spring 107. The left part of the sliding plate 1 is slidably connected to the extrusion block 106. The front side of the extrusion block 106 is set with an inclined surface, and the convex plate 8 can then squeeze the adjacent extrusion block 106, so that when the device is folded, there is no need to manually squeeze the extrusion block 106 multiple times. The rear side of the extrusion block 106 is also set with an inclined surface, and the extrusion block 106 moves backward to better squeeze the sliding rod 105, so that the sliding rod 105 moves to the right and separates from the fixed plate 103, thereby canceling the limit rod 101. The right part of the front sliding plate 1 is also slidably connected to the extrusion block 106, and the extrusion block 106 and the sliding plate 1 are fixed with a coil spring 107. The backward movement of the extrusion block 106 will squeeze the sliding rod 105, thereby causing the sliding rod 105 to move in the direction away from the limit rod 101, thereby causing the sliding rod 105 to no longer limit the limit rod 101.

[0033] When the sliding plate 1 is pulled out, the convex plate 8 on the adjacent sliding plate 1 will slide in the sliding groove 21. At this time, the convex plate 8 no longer squeezes the squeezing block 106, and the squeezing block 106 no longer squeezes the sliding rod 105. The coil spring 107 and the return spring 104 are restored, thereby restoring the squeezing block 106 and the sliding rod 105 to their original positions. After the sliding plate 1 is pulled out, the staff can press the limit rod 101 to make the limit rod 101 move downward. The downward movement of the limit rod 101 will drive the fixed plate 103 to move downward together. At this time, the compression spring 102 is compressed, and the downward movement of the fixed plate 103 will squeeze the sliding rod 105. Since the fixed plate 103 and the sliding rod 105 are relative to each other, The sides close to each other are both inclined, so that the sliding rod 105 moves in the direction away from the fixed plate 103. At this time, the return spring 104 is compressed, so that the fixed plate 103 can continue to move downward. When the fixed plate 103 continues to move downward and separates from the sliding rod 105, the return spring 104 is restored, so that the sliding rod 105 moves in the direction close to the fixed plate 103 and returns to its original position. At this time, the sliding rod 105 is just stuck on the upper part of the fixed plate 103, thereby limiting the limit rod 101 and the fixed plate 103. Since the lower part of the limit rod 101 is conical, the sliding plate 1 is fixed to the ground, thereby preventing the device from being blown down by the wind.

[0034] When the sliding plate 1 is to be folded, the squeezing block 106 is squeezed, so that the squeezing block 106 moves backward to squeeze the sliding rod 105. Since the front and rear sides of the squeezing block 106 are both inclined, the sliding rod 105 moves away from the fixed plate 103, the return spring 104 is compressed, and the sliding rod 105 is separated from the fixed plate 103. The compression spring 102 is restored, and the limiting rod 101 and the fixed plate 103 move upward to restore. The limiting rod 101 no longer limits the sliding plate 1, making it convenient to fold the sliding plate 1.

[0035] like Figure 1 、 Figure 3 、 Figure 5 and Figure 8 As shown, it also includes a sliding block 111 and a fixed rod 112. The right part of the front sliding plate 1 is slidably connected to the limit rod 101, and the right parts of other sliding plates 1 are rotatably connected to the sliding block 111. The upper parts of the sliding blocks 111 are slidably connected to the fixed rod 112. The fixed rod 112 slides to the left and is inserted into the adjacent sliding plate 1, so that the fixed rod 112 can limit the sliding plate 1.

[0036] When the sliding plate 1 is pulled out, the fixing rod 112 will slide along the adjacent sliding plate 1. After the sliding plate 1 is pulled out, the fixing rod 112 is manually pulled to separate the fixing rod 112 from the sliding plate 1. At this time, the angle of the sliding plate 1 can be swung to adjust the placement position of each sliding plate 1, so that it can be changed according to different municipal engineering areas, making the device more flexible.

[0037] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 and Figure 10 As shown, it also includes a driving mechanism, which includes a connecting plate 121, a rotating rod 122, a gear 2 123, a gear 3 124, a gear 4 125, a rack 2 126 and a moving plate 127. The front part of the front sliding plate 1 is fixedly connected to the connecting plate 121, the middle part of the connecting plate 121 is rotatably connected to the rotating rod 122, the lower part of the rotating rod 122 is fixedly connected to the gear 2 123, the middle part of the connecting plate 121 is rotatably connected to the gear 2 123, the gear 3 124 and the gear 4 125, the two gear 2s 123 are meshed with the gear 3 124, the gear 2 123 on the connecting plate 121 is meshed with the gear 1 3 on the front sliding plate 1, the middle part of the front sliding plate 1 is slidably connected to the moving plate 127, the front part of the moving plate 127 is fixedly connected to the rack 2 126, the rack 2 126 is meshed with the gear 4 125, and the rotation of the gear 2 123 on the connecting plate 121 will drive the gear 4 125 to rotate.

[0038] When the gear 126 is extended, the gear 127 is rotated and the gear 127 is rotated, so that the gear 126 is rotated and the gear 126 is rotated.

[0039] When the sliding plate 1 is to be folded up, the rotating rod 122 is rotated in the opposite direction, so that the gear 2 123, the gear 3 124 and the gear 4 125 are all reversed, thereby reversing the gear 1 3 on the front sliding plate 1, and then the rotating plate 6 and the telescopic rod 7 are folded up. At the same time, the rack 2 126 will also return to its original position. The rack 2 126 will also return to its original position and squeeze the squeezing block 106, so that the limit rod 101 and the fixed plate 103 move upward under the action of the compression spring 102. At the same time, when the front sliding plate 1 is folded up, the convex plate 8 of the front sliding plate 1 will slide in the sliding groove 21, and then squeeze the rotating plate 6 on the adjacent sliding plate 1, so that there is no need to manually squeeze the rotating plate 6, reducing the manual workload, saving time and effort.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
