Description
Technical Field
[0001] The utility model relates to the field of ditch covers, in particular to an anti-blocking highway ditch cover. Background Art
[0002] In order to avoid water accumulation on the road on rainy days, side ditches are generally set up on both sides of the road. The accumulated water on the road will flow into the side ditches, so that there will not be a large amount of water accumulation on the road, affecting pedestrians and vehicle driving. Cover plates are installed above the side ditches.
[0003] Although there are many types and quantities of highway ditch covers on the market, most of them have the disadvantage that the water inlet set on the cover is easily blocked by some objects. In many cases, large heavy objects will press on the water inlet, preventing water from flowing in, seriously affecting the drainage effect. The existing highway ditch covers are partially integrated designs, which are costly and heavy, and require heavy workloads for workers. In addition, it is inconvenient to remove the cover and clean the inside of the ditch.
[0004] Therefore, those skilled in the art provide an anti-clogging highway ditch cover to solve the problems raised in the above background technology. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an anti-clogging highway ditch cover. The ditch cover is provided with an inclined groove which is narrow at the top and wide at the bottom, and an outer drainage groove and an inner drainage groove are provided on both sides. When foreign objects are stuck in the narrow part of the inclined groove, they are easily washed down into the ditch by the water flows led out from both sides. A shock-absorbing belt is provided to ensure that there is always a certain distance between large foreign objects and the outer surface of the inclined groove to prevent the water inlet from being blocked. The overall structure reduces weight while improving stability and strength. Slopes and limit blocks are provided to facilitate the removal of the cover, thereby reducing the workload of workers.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-blocking highway ditch cover, comprising a ditch, a cover frame and an inner cover, wherein the upper end of the cover frame is provided with a plurality of external drainage grooves near both sides, the upper end of the cover frame is fixedly provided with limiting blocks near the front and rear, both sides of the inner cover are provided with a plurality of internal drainage grooves, the upper end of the inner cover is provided with a plurality of inclined grooves, the inner cover is provided with a plurality of shock-absorbing belts penetrating near the upper end, the inner part of the plurality of shock-absorbing belts is provided with pressure plates slidingly penetrating near the upper part, the inner sides of the lower ends of the plurality of shock-absorbing belts are fixedly provided with a plurality of dampers, the upper end of the inner cover is provided with a lifting handle rotatably provided in the groove near the front and rear ends, and the inner cover is provided with a slope near the lower part of the front and rear ends;
[0007] The inner cover plate is provided with an outer layer around the body, a shock-absorbing plate is provided inside the inner cover plate near the shock-absorbing belt, a steel mesh layer is provided inside the inner cover plate near the shock-absorbing plate, a plurality of reinforcing columns are provided inside the inner cover plate near the bending part of the steel mesh layer, two honeycomb panels are provided inside the inner cover plate, and the remaining space of the inner cover plate is provided with an inner layer;
[0008] Through the above technical scheme, multiple limit blocks and corresponding slopes cooperate, and after pulling the lifting handle, the inner cover plate can be dragged out in more directions. The steel mesh layer, shock-absorbing plate and honeycomb plate designed inside the inner cover plate reduce the overall weight of the inner cover plate, making it easier to take out. The internal structure of the inner cover plate as above can effectively improve the shock absorption effect and bending strength while cooperating with the outer layer and the inner layer. The shock-absorbing belt arranged at the upper end of the inner cover plate further reduces the damage caused by the crushing of heavy objects such as cars. When foreign objects are piled on the upper end of the inner cover plate, they will not contact the inclined groove due to the influence of the shock-absorbing belt, ensuring that water will not be blocked. Multiple external drainage grooves and internal drainage grooves can further improve the hydrophobic ability. Multiple inclined grooves can ensure that foreign objects will not be stuck in the groove for too long, reduce the impact of foreign object blockage, and improve drainage capacity.
[0009] Furthermore, a plurality of the outer drainage grooves are connected, and the outer drainage grooves are located at a height higher than the inner drainage grooves;
[0010] Through the above technical solution, while ensuring the stability of the inner cover plate structure, the remaining space is used as much as possible to add water channels to improve the drainage capacity.
[0011] Furthermore, the plurality of inclined grooves extend from the upper end of the inner cover plate to the lower end of the inner cover plate, and the plurality of inclined grooves are designed to be narrow at the top and wide at the bottom;
[0012] Through the above technical solution, the upper part of the inclined groove is narrower, and the contact area with the inner cover plate is limited when foreign objects are stuck, which will cause the foreign objects to not be clamped too tightly. Combined with the lateral water outlet of the inner drainage grooves on both sides, the foreign objects are easily washed into the side ditch due to the impact of water on both sides.
[0013] Furthermore, the size of the slope is matched with the size of the slope of the limit block, and a plurality of limit blocks with equal distances are designed on the cover frame, and the distance between each two adjacent limit blocks is equal to the width of the inner cover;
[0014] The above technical solution makes it easier to position and install the inner cover.
[0015] Furthermore, the shock absorbing plate is a rubber shock absorbing plate and has a rigid steel frame inside;
[0016] Through the above technical solution, the rubber shock-absorbing plate has good durability and torsional stiffness, which can effectively reduce the vibration loss caused by the inner cover plate being rolled over by the vehicle, improve stability and reduce the overall weight.
[0017] Furthermore, the steel mesh layer is composed of a plurality of steel bars forming a mesh structure and is arranged in a bent manner. The steel bars of the steel mesh layer are made of ordinary carbon steel, and the reinforcement column is composed of ordinary carbon steel wrapped with carbon fiber reinforced polymer.
[0018] Through the above technical solution, the internal arrangement of a steel mesh layer can effectively increase the bearing capacity of the inner cover plate, enhance the crack resistance, and improve durability. The arrangement of reinforcement columns can further ensure the structural stability of the steel mesh layer.
[0019] Further, the honeycomb panel is a glass fiber honeycomb panel;
[0020] Through the above technical solution, the glass fiber honeycomb panel has the characteristics of light weight and high strength, can play the role of shock absorption and noise reduction, and is moisture-proof and corrosion-resistant. It is suitable for a variety of lightweight fields, ensuring the stability of the inner cover structure while reducing the overall weight.
[0021] Further, the outer layer is reactive powder concrete, and the inner layer is steel fiber concrete;
[0022] Through the above technical scheme, the active powder concrete has fewer micro-cracks on the surface, excellent durability and low brittleness, and has ultra-high mechanical properties and good environmental performance. It is suitable for the outer surface of the inner cover plate. Steel fiber concrete can effectively improve the internal tightness and improve the tensile crack resistance.
[0023] The utility model has the following beneficial effects:
[0024] 1. The utility model proposes an anti-blocking highway ditch cover, which reduces the contact area between foreign objects and the inner cover when they are stuck in the ditch by opening a plurality of oblique grooves which are narrow at the top and wide at the bottom. External drainage grooves and internal drainage grooves are designed on both sides. When the water flow is large, the foreign objects stuck in the oblique grooves can be impacted to facilitate flushing them into the ditch. When large foreign objects cover the inner cover, the shock-absorbing belts are provided to support the large foreign objects, thereby preventing the large foreign objects from covering the oblique grooves and affecting drainage, thereby greatly improving the drainage and anti-blocking capabilities.
[0025] 2. The utility model proposes an anti-clogging highway ditch cover, which adopts a series of reinforcing materials to improve strength and durability while lightening the internal structure. The outer layer adopts active powder concrete and the inner layer adopts steel fiber concrete to increase the overall compactness. A steel mesh layer and reinforcing columns are added inside to improve the crack resistance and bending resistance. A shock-absorbing plate and a honeycomb plate are also provided inside to improve the shock-absorbing and buffering capacity and service life. This design reduces the overall weight compared with the traditional inner cover. By setting a lifting handle, the slope of the inner cover can be taken out along the slope of the limit block, reducing the workload of the workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Reference Figure 1-5, the utility model provides an embodiment: an anti-blocking highway ditch cover, including a ditch 1, a cover frame 2 and an inner cover 4. In order to improve the ability to evacuate water, a plurality of outer drainage grooves 8 are opened near both sides of the upper end of the cover frame 2. The outer drainage grooves 8 are connected to the inner drainage grooves 10, and water can flow to the inside of the ditch 1 along the connecting path therebetween. In order to facilitate the positioning and installation of the inner cover 4 and facilitate subsequent removal, a limiting block 3 is fixedly arranged at the front and rear ends of the upper end of the cover frame 2. The limiting block 3 is triangular in shape, and the size of its inclined surface fits the size of the slope 9, so that there are more directions for taking out the dragging and pulling handle 7, and it is easier to take out the inner cover 4. A plurality of inner drainage grooves 10 are opened on both sides of the inner cover 4;
[0035] The grooves on the conventional inner cover plate 4 have the same width from top to bottom, which will cause foreign objects to get stuck on them and not be easily washed off even if they are washed by water. To avoid this, a plurality of inclined grooves 6 are provided at the upper end of the inner cover plate 4. The inclined grooves 6 are designed to be narrow at the top and wide at the bottom. Foreign objects will only get stuck in the narrow part and have a small contact area with the inner cover plate 4. When they are impacted by water flowing out of the inner drainage groove 10, they are more likely to be washed off into the side ditch 1. If the upper end of the inner cover plate 4 is a flat surface, its drainage capacity will be seriously affected when large foreign objects are accumulated. Therefore, a plurality of shock-absorbing belts 5 are provided through the upper end of the inner cover plate 4, which can play a shock-absorbing and buffering effect and ensure that large foreign objects will not contact the inclined grooves 6 when accumulated, thereby ensuring drainage capacity.
[0036] A pressure plate 11 is slidably provided inside the multiple shock-absorbing belts 5 at the upper part, and multiple dampers 12 are fixedly provided on the inner side of the lower end of the multiple shock-absorbing belts 5. A lifting handle 7 is rotatably provided in the groove at the front and rear ends of the upper end of the inner cover plate 4. When it is needed, the lifting handle 7 can be turned to a suitable position for dragging, without buckling or using other tools, and it is more convenient to take it away. A slope 9 is provided at the lower part of the front and rear ends of the inner cover plate 4, and it is more labor-saving to drag along the slope 9;
[0037] In order to improve the strength of the inner cover plate 4 and make the whole body lighter, an outer layer 13 is arranged around the inner cover plate 4. The outer layer 13 is made of active powder concrete, which has many excellent properties, so that other structures can be added inside more safely. A shock-absorbing plate 17 is arranged inside the inner cover plate 4 near the bottom of the shock-absorbing belt 5. The shock-absorbing plate 17 is made of a rubber shock-absorbing plate. The rigid skeleton arranged inside the shock-absorbing plate 17 effectively connects and stabilizes it, effectively plays a role in buffering and shock-absorbing, and reduces the overall mass.
[0038] A steel mesh layer 14 is provided inside the inner cover plate 4 near the bottom of the shock absorbing plate 17. The steel mesh layer 14 is a mesh arrangement and is designed with an upward curved protrusion on the top. A reinforcing column 18 is provided below the protrusion to further improve stability, improve the bending and cracking resistance of the inner cover plate 4, and improve durability. A plurality of reinforcing columns 18 are provided below the inner cover plate 4 near the bending part of the steel mesh layer 14. The reinforcing columns 18 are formed by carbon fiber reinforced polymer wrapped around ordinary carbon steel to make the internal structure more stable. Two honeycomb panels 16 are provided inside the inner cover plate 4 near the bottom. They are glass fiber honeycomb panels, which are suitable for a variety of lightweight fields, have high strength, can achieve a shock absorbing effect, and are waterproof and corrosion-resistant. An inner layer 15 is provided in the remaining space of the inner cover plate 4. The inner layer 15 is steel fiber concrete, which makes the internal density higher and more compact, and improves the overall strength.
[0039] Multiple limit blocks 3 and corresponding slopes 9 cooperate, and after pulling open the lifting handle 7, the inner cover plate 4 can be dragged out in more directions. The steel mesh layer 14, shock-absorbing plate 17 and honeycomb plate 16 designed inside the inner cover plate 4 reduce the overall weight of the inner cover plate 4, making it easier to take out. The internal structure of the inner cover plate 4 as above is effectively improved while cooperating with the outer layer 13 and the inner layer 15. The shock-absorbing belt 5 set at the upper end of the inner cover plate 4 further reduces the damage caused by the crushing of heavy objects such as cars. When foreign objects are piled on the upper end of the inner cover plate 4, they will not contact the chute 6 due to the influence of the shock-absorbing belt 5, ensuring that water will not be blocked. Multiple external drainage grooves 8 and internal drainage grooves 10 can further improve the hydrophobic ability. Multiple chute 6 can ensure that foreign objects will not be stuck in the groove for too long, reduce the impact of foreign object blockage, and improve drainage capacity;
[0040] Multiple outer drainage grooves 8 are connected to the inner drainage grooves 10. The height of the outer drainage grooves 8 is higher than that of the inner drainage grooves 10. Under the condition of ensuring the stability of the structure of the inner cover plate 4, the remaining space is used as much as possible to add waterways to improve the drainage capacity. Multiple inclined grooves 6 run from the upper end of the inner cover plate 4 to the lower end of the inner cover plate 4. Multiple inclined grooves 6 are designed to be narrow at the top and wide at the bottom. The upper part of the inclined grooves 6 is narrower. When foreign objects are stuck, the contact area with the inner cover plate 4 is limited, which will cause the foreign objects not to be clamped too tightly. In conjunction with the lateral water discharge of the inner drainage grooves 10 on both sides, the foreign objects are easily washed down into the side ditch 1 by the impact of water on both sides.
[0041] The size of the slope 9 is matched with the size of the slope of the limit block 3. A plurality of equidistant limit blocks 3 are designed on the cover frame 2. The distance between each two adjacent limit blocks 3 is equal to the width of the inner cover 4, so that the inner cover 4 is easier to be positioned and installed. The shock-absorbing plate 17 is a rubber shock-absorbing plate, and has a rigid steel skeleton inside. The rubber shock-absorbing plate has good durability and torsional rigidity, which can effectively reduce the vibration loss caused by the inner cover 4 being rolled over by the vehicle, improve stability and reduce the overall weight. The steel mesh layer 14 is composed of a plurality of steel bars to form a mesh structure, and is bent. The steel bars of the steel mesh layer 14 are made of ordinary carbon steel. The reinforcement column 18 is composed of ordinary carbon steel wrapped with a carbon fiber reinforced polymer. The steel mesh layer 14 is arranged inside to effectively increase the bearing capacity of the inner cover 4, enhance crack resistance, and improve durability. The reinforcement column 18 is arranged to further ensure the structural stability of the steel mesh layer 14.
[0042] The honeycomb panel 16 is a glass fiber honeycomb panel. The glass fiber honeycomb panel has the characteristics of light weight and high strength. It can reduce shock and sound, and is moisture-proof and corrosion-resistant. It is suitable for a variety of lightweight fields. While ensuring the structural stability of the inner cover plate 4, the overall weight is reduced. The outer layer 13 is active powder concrete, and the inner layer 15 is steel fiber concrete. The active powder concrete has few micro-cracks on the surface, has excellent durability and low brittleness, and has ultra-high mechanical properties and good environmental protection performance. It is suitable for the outer surface of the inner cover plate 4. Steel fiber concrete can effectively improve the internal tightness and improve the tensile crack resistance.
[0043] Working principle: workers can place the inner cover plate 4 between two adjacent limit blocks 3. If they need to take it out, they only need to turn the lifting handle 7 to the appropriate position, and then pull out the inner cover plate 4. During the pulling process, the inner cover plate 4 can move along the slope 9. After the inner cover plate 4 is placed, the outer drainage groove 8 and the inner drainage groove 10 will be connected, and water will flow into the outer drainage groove 8 and out of the inner drainage groove 10. If foreign matter is stuck in the inclined groove 6, when the water flow is large, it can produce a lateral impact on it, which can easily cause the foreign matter to fall into the side ditch 1. When a moving vehicle runs over it, the shock-absorbing belt 5 will The multiple dampers 12 can play a buffering and shock-absorbing role. When large foreign objects accumulate, the shock-absorbing belt 5 can also play a supporting role to prevent the large foreign objects from contacting the chute 6 and affecting normal drainage. The outer layer 13 of the inner cover plate 4 is made of active powder concrete, and the inner layer 15 is made of steel fiber concrete, which makes the overall structure more stable and tight, and improves the crack resistance and bending resistance. The steel mesh layer 14 is arranged inside to further improve the stability and crack resistance. The shock-absorbing plate 17 and the honeycomb plate 16 can not only improve the overall performance, but also are lighter in weight than the traditional inner cover plate 4, and are easy to put in and remove.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
