Description

Technical Field

[0001] The utility model belongs to the technical field of road and bridge protection, and in particular relates to a road and bridge anti-collision structure. Background Art

[0002] In today's world where automobiles are developing extremely rapidly, with the gradual increase in the number of cars on the road, vehicle accidents are also increasing. In most cases, especially when vehicles are driving at high speeds, once an accident occurs, the vehicle will be out of control and will inevitably collide with the crash barrier of the road or bridge, causing damage to people and property.

[0003] A road and bridge anti-collision protection device disclosed in Chinese utility model patent application CN210597139U includes a barrel body located on one side of a crash barrier and in a rectangular shape, an upper end surface of the barrel body is provided with an opening, and an edge of the upper end surface of the barrel body is provided with a baffle. Although the utility model has the advantages of reducing the impact force generated when a vehicle loses control and collides with a road and bridge crash barrier, and reducing damage to the road and bridge crash barrier and the vehicle, since the drainage chamber and the water storage chamber in the barrel body are separated by a buffer plate, when external dust enters the water storage chamber from the opening, the dust cannot be discharged. After a long time, the dust will accumulate in the barrel body. When a large amount of dust accumulates in the barrel body, the hardness of the barrel body will increase, and its buffering performance will be reduced, that is, the protection performance of the barrel body will be reduced.

[0004] In order to avoid the above technical problems, it is necessary to provide a road bridge anti-collision structure to overcome the above defects in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-4As shown, a road bridge anti-collision structure provided by the utility model includes an anti-collision barrel 1, which is a rectangular structure. The anti-collision barrel 1 is installed on the bridge wall 2. A plurality of anti-collision barrels 1 are spliced ​​and installed in sequence to cover the bridge wall 2. The interior of the anti-collision barrel 1 is horizontally slidably connected with a buffer plate 3, and a buffer spring 4 is connected between the buffer plate 3 and the anti-collision barrel 1. The buffer plate 3 divides the interior of the anti-collision barrel 1 into a water storage chamber 5 and a drainage chamber 6. The drainage chamber 6 is close to the bridge wall 2. A drainage hole 7 is opened on the side of the anti-collision barrel 1 close to the bridge wall 2. A water outlet hole 8 connected to the drainage hole 7 is opened on the bridge wall 2. A sand discharge hole 9 is opened on the side of the anti-collision barrel 1. A sand discharge hole 10 connected to the sand discharge hole 9 is opened on the bridge wall 2. The sand discharge hole 9 is located below the drainage hole 7. A water inlet 11 is opened on the top of the anti-collision barrel 1, and also includes:

[0023] The automatic sand discharge mechanism 12 is installed inside the crash bucket 1. The bottom of the buffer plate 3 elastically abuts against the automatic sand discharge mechanism 12, thereby preventing the water in the water storage chamber 5 from entering the drainage chamber 6 from the bottom of the buffer plate 3. When it rains, the automatic sand discharge mechanism 12 is used to discharge the sand and dust in the crash bucket 1.

[0024] In the embodiment of the present utility model, Figure 2-3 As shown, as a preferred embodiment of the utility model, the automatic sand discharge mechanism 12 includes a lifting plate 121, and the lifting plate 121 is vertically slidably connected to the inside of the anti-collision barrel 1, the top of the lifting plate 121 is elastically abutted against the bottom of the buffer plate 3, and a water baffle 122 is fixedly connected to one side of the top of the lifting plate 121, and the water baffle 122 blocks the drainage hole 7, and a first compression spring 123 is connected between the lifting plate 121 and the bottom of the anti-collision barrel 1, and an inclined first guide plate 124 is fixedly connected to the inside of the anti-collision barrel 1, and a vertical fixed plate 125 is fixedly connected to the end of the first guide plate 124, and an inclined second guide plate 125 is fixedly connected to the side of the fixed plate 125 6. The end of the second guide plate 126 is connected to the bottom of the sand discharge hole 9, and a water retaining plate 127 is fixedly connected to the side of the lifting plate 121. A sliding hole for the water retaining plate 127 to pass through is opened on the second guide plate 126, and a sand passing hole 128 is opened on the side of the water retaining plate 127. A baffle 129 is fixedly connected to the inside of the crash bucket 1, and the side of the baffle 129 is in contact with the water retaining plate 127. Initially, the baffle 129 blocks the sand passing hole 128. Therefore, a sand storage trough is formed between the water retaining plate 127, the baffle 129, the second guide plate 126 and the fixed plate 125. When it is not raining, the sand and dust entering the crash bucket 1 will settle in the sand storage trough, which is convenient for the discharge of sand and dust.

[0025] In the embodiment of the present utility model, Figure 2 and Figure 4As shown, as a preferred embodiment of the utility model, the buffer plate 3 includes an anti-collision plate 31, and the anti-collision plate 31 is slidably connected to the inside of the anti-collision barrel 1. The side of the anti-collision plate 31 is slidably connected with a water cut-off plate 32, and a second compression spring 33 is connected between the water cut-off plate 32 and the anti-collision plate 31, and the bottom of the water cut-off plate 32 abuts against the lifting plate 121.

[0026] In the embodiment of the present utility model, Figure 2 As shown, as a preferred embodiment of the utility model, the top of the crash bucket 1 is provided with an inclined top plate, the water inlet 11 is provided at the end of the top plate, and the water inlet 11 is located above the water storage chamber 5, and the height of the top of the crash bucket 1 is greater than the height of the top plate, so as to facilitate rainwater to gather at the water inlet 11.

[0027] In the embodiment of the present utility model, Figure 1-2 As shown, as a preferred embodiment of the utility model, the side of the crash bucket 1 away from the bridge wall 2 is set as a trapezoidal structure, which increases the volume of the water storage chamber 5 and lowers the center of gravity of the crash bucket 1, thereby making the crash bucket 1 more stable.

[0028] In the embodiment of the utility model, as a preferred embodiment of the utility model, the crash bucket 1 is made of plastic material, which reduces the reaction force of the crash bucket 1 and thus improves the protection capability of the crash bucket 1 .

[0029] When installing the anti-collision structure of the road and bridge, the anti-collision barrels 1 are sequentially spliced ​​and installed on the side walls of the bridge. When it rains, rainwater enters the water storage chamber 5 from the water inlet 11 and is then stored. When a car hits the anti-collision barrel 1, the rainwater increases the buffering force of the anti-collision barrel 1 and reduces the damage to the car. After the external dust enters the water storage chamber 5, the dust will settle on the first guide plate 124 and the second guide plate 126. When it rains, after the rainwater overflows the buffer plate 3, the rainwater will enter the drainage chamber 6. Since the drainage hole 7 is blocked by the water retaining plate 122, the rainwater will gradually accumulate. Under the gravity of the rainwater, the lifting plate 121 descends, and the lifting plate 121 drives the water retaining plate 122 and the water retaining plate 127 to descend. Thereby, the drainage hole 7 and the sand-passing hole 128 are exposed, and the sand and dust on the second guide plate 126 are washed out from the sand-passing hole 128 by the rainwater in the water storage chamber 5, and then discharged from the anti-collision barrel 1 after passing through the sand-discharging hole 9 and the sand-discharging hole 10, while the rainwater in the drainage chamber 6 will be discharged from the drainage hole 7 and the water-discharging hole 8. When the amount of water in the drainage chamber 6 is insufficient, under the action of the first compression spring 123, the lifting plate 121 rises, the water baffle plate 122 divides the drainage hole 7, and the baffle plate 129 blocks the sand-passing hole 128 to prevent the rainwater in the anti-collision barrel 1 from being discharged. The device can intermittently discharge the mud and sand in the anti-collision barrel 1 to avoid the problem of reducing the protective strength of the anti-collision barrel 1 due to the filling of the mud and sand in the anti-collision barrel 1.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
