Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a municipal road surface drainage structure. Background Art

[0002] The municipal drainage system is an important part of municipal engineering. It is mainly responsible for draining away the accumulated water in the city, especially on the road, in a timely manner to prevent the accumulated water from being too deep and affecting the traffic in the city. The common municipal drainage structure is a drainage ditch buried under the road surface. The upper side of the drainage ditch is paved with grates to prevent pedestrians and vehicles from falling into the drainage ditch, and to prevent larger debris from entering the drainage ditch and blocking the drainage ditch.

[0003] A Chinese patent with publication number CN220225646U was searched and disclosed, which is a municipal pavement drainage structure. In the above drainage structure, when large areas of debris such as fallen leaves are brought to the top of the grille by the water flow, the grille is easily covered, making it difficult for the water flow to pass through the grille into the sink for filtration, resulting in water accumulation around the drainage structure, blocking the drainage structure and affecting the drainage function. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a municipal pavement drainage structure. When the fallen leaves cover the top of the second filter plate and water accumulates around it, the elastic member keeps the inclined clamping block in a balanced state, and the force of the accumulated water flow breaks the balance and squeezes the connecting plate. At the same time, the accumulated water flows through the water holes, increasing the impact force of the accumulated water and driving the inclined sliding block to move. The inclined sliding block squeezes the inclined clamping block to move upward, driving the second filter plate to move upward. At this time, a space is generated between the second filter plate and the first filter plate, and the accumulated water flows into the first filter plate through the space and enters the drainage trough for filtration. At the same time, the up and down movement of the second filter plate will also generate vibration to shake off the debris on the top.

[0005] The technical solution to achieve the purpose of the utility model is: a municipal pavement drainage structure, including a drainage frame, a first filter plate is fixedly connected to the top of the drainage frame, and two slots are provided on both sides of the top of the drainage frame, characterized in that: a second filter plate is provided directly above the first filter plate, and two oblique blocks are fixedly connected on both sides of the bottom of the second filter plate, four oblique blocks are respectively slidably connected to the four slots, the bottoms of the four slots are slidably connected with oblique sliding blocks, the four oblique sliding blocks are respectively adapted to the four oblique blocking blocks, one side of the four oblique sliding blocks are provided with a water hole, the tops of the four oblique sliding blocks are fixedly connected with sliding blocks, and the tops of two adjacent sliding blocks are commonly fixedly connected with a connecting plate.

[0006] In some embodiments, one side inner wall of each of the four slots is fixedly connected with an elastic member, and one end of the four elastic members is fixedly connected to one side of each of the four sliding blocks.

[0007] In some embodiments, a drainage groove is provided at the bottom of the drainage frame, and two fixing blocks are fixedly connected to an outer wall of one side of the drainage groove. Two fixing grooves are provided on an inner wall of one side of the drainage frame, and the two fixing blocks are respectively adapted to the two fixing grooves.

[0008] In some embodiments, threaded holes are formed on the tops of the two fixing blocks, two bolts are screwed on the top of the drainage frame, and the bottom ends of the two bolts are screwed into the two threaded holes respectively.

[0009] In some embodiments, the inner wall of the drainage groove is fixedly connected with a rotating shaft, and a third filter plate is rotatably connected to the rotating shaft, and one end of the third filter plate is in contact with one inner wall of the drainage groove.

[0010] Compared with the prior art, the present invention has the following significant advantages:

[0011] First, the utility model sets the second filter plate. When the fallen leaves cover the top of the second filter plate and water accumulates around it, the elastic member keeps the oblique clamping block in a balanced state. The force of the accumulated water flow breaks the balance and squeezes the connecting plate. At the same time, the accumulated water flows through the water holes, increasing the impact force of the accumulated water and driving the oblique slider to move. The oblique slider squeezes the oblique clamping block to move upward, driving the second filter plate to move upward. At this time, a space is generated between the second filter plate and the first filter plate. The accumulated water flows into the first filter plate through the space and enters the drainage groove for filtration. At the same time, the up and down movement of the second filter plate will also generate vibration to shake off the debris on the top.

[0012] Second, the utility model is provided with bolts. When it is necessary to clean the debris in the drainage trough, the second filter plate is taken out upwards, and the two bolts are rotated to make the two bolts away from the two threaded holes, so that the two fixing blocks and the two fixing grooves are loosened, and the drainage trough is moved until the two fixing blocks leave the fixing groove, and the debris in the drainage trough can be poured out;

[0013] The problem that fallen leaves and other debris are easily covered by the grille when they are carried to the top of the grille by the water flow makes it difficult for the water flow to pass through the grille into the sink for filtration, which may cause water accumulation around the drainage structure and block the drainage structure.

[0021] 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.

[0022] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] The utility model provides a municipal pavement drainage structure through improvement. The technical solution of the utility model is:

[0025] like Figure 1-Figure 4As shown, a municipal road drainage structure includes a drainage frame 1. When installed, the drainage frame 1 is parallel to the road surface. A first filter plate 101 is fixedly connected to the top of the drainage frame 1. The filter holes of the first filter plate 101 are slightly larger than the filter holes of the second filter plate 2, so that some debris in the accumulated water can be filtered through the drainage groove 3. Two card slots 102 are provided on both sides of the top of the drainage frame 1. The characteristics are: a second filter plate 2 is provided directly above the first filter plate 101, and two oblique card blocks 201 are fixedly connected to the two sides of the bottom of the second filter plate 2. The four oblique card blocks 20 1 are respectively slidably connected in the four card slots 102, the bottoms of the four card slots 102 are slidably connected with oblique sliding blocks 502, the four oblique sliding blocks 502 are respectively adapted to the four oblique card blocks 201, one side of the four oblique sliding blocks 502 is provided with a water hole 504, the accumulated water impacts the water hole 504 to increase the impact force of the accumulated water on the oblique sliding blocks 502, and at the same time facilitates the discharge of the accumulated water in the card slot 102, the tops of the four oblique sliding blocks 502 are fixedly connected with the sliding blocks 501, and the tops of two adjacent sliding blocks 501 are commonly fixedly connected with a connecting plate 503.

[0026] Through the setting of the second filter plate 2, when the fallen leaves cover the top of the second filter plate 2 and water accumulates around it, the elastic member 5 keeps the oblique clamping block 201 in a balanced state, and the force of the accumulated water flow breaks the balance and squeezes the connecting plate 503. At the same time, the accumulated water impacts the water hole 504, driving the oblique sliding block 502 to move. The oblique sliding block 502 squeezes the oblique clamping block 201 to move upward, driving the second filter plate 2 to move upward. At this time, a space is generated between the second filter plate 2 and the first filter plate 101, and the accumulated water flows into the first filter plate 101 through the space and enters the drainage groove 3 for filtration. At the same time, the up and down movement of the second filter plate 2 will also generate vibration to shake off the debris on the top.

[0027] The provision of the second filter plate 2 allows most debris to be preliminarily intercepted before reaching the first filter plate 101, thereby reducing the risk of clogging of the first filter plate 101 and improving drainage efficiency.

[0028] The filter holes of the first filter plate 101 are slightly larger than those of the second filter plate 2, which not only ensures an effective filtering effect but also avoids the problem of poor drainage caused by too small filter holes.

[0029] like Figure 2 As shown, in one embodiment, in order to extend the service life, the elastic member 5 is made of metal, the inner wall of one side of the four slots 102 is fixedly connected with the elastic member 5, and one end of the four elastic members 5 is fixedly connected to one side of the four sliding blocks 501 respectively.

[0030] Through the setting of the elastic member 5, the elastic member 5 gives elastic force to the sliding block 501, so that the inclined sliding block 502 gives the inclined clamping block 201 an extrusion force perpendicular to the inclined surface, and the vertical component of the extrusion force offsets the gravity, so that the inclined clamping block 201 is in a balanced state. Therefore, only a little extra force of the flow of accumulated water is needed to drive the inclined sliding block 502 to move, thereby driving the inclined clamping block 201 to move upward, and driving the second filter plate 2 to move upward.

[0031] When the accumulated water flows and drives the inclined slider to move, the elastic member 5 will be stretched or compressed. Once the accumulated water pressure decreases or disappears, the elastic member 5 can automatically restore its original state, thereby driving the sliding block 501 and the inclined slider to reset. This automatic reset function ensures the stability and sustainability of the drainage structure.

[0032] Preferably, the elastic member is a telescopic spring.

[0033] like Figure 4 As shown, in one embodiment, the outer wall of the drainage groove 3 is provided with a plurality of water-permeable holes, the bottom of the drainage frame 1 is provided with the drainage groove 3, one side of the outer wall of the drainage groove 3 is fixedly connected with two fixed blocks 301, and one side of the inner wall of the drainage frame 1 is provided with two fixed grooves 103, and the two fixed blocks 301 are respectively adapted to the two fixed grooves 103.

[0034] By providing the drainage groove 3 , further filtering of the flowing water is achieved, and larger impurities are retained in the drainage groove 3 .

[0035] like Figure 1 As shown, in one embodiment, in order to extend the service life, the two bolts 4 are made of metal, and threaded holes 303 are opened on the tops of the two fixing blocks 301. The top of the drainage frame 1 is screwed with two bolts 4, and the bottom ends of the two bolts 4 are screwed into the two threaded holes 303 respectively.

[0036] Through the setting of the bolts 4, when it is necessary to clean the debris in the drainage trough 3, the second filter plate 2 is taken out upwards, and the two bolts 4 are rotated to make the two bolts 4 away from the two threaded holes 303, so that the two fixing blocks 301 and the two fixing grooves 103 are loosened, and the drainage trough 3 is moved until the two fixing blocks 301 leave the fixing grooves 103, and the debris in the drainage trough 3 can be poured out.

[0037] like Figure 2 As shown, in one embodiment, the inner wall of the drainage trough 3 is fixedly connected with a rotating shaft 302, and the third filter plate 6 is rotatably connected to the rotating shaft 302. One end of the third filter plate 6 is in contact with one side inner wall of the drainage trough 3. The length of the third filter plate 6 is greater than the height of the drainage trough 3, so that it can be placed at an angle.

[0038] By setting the third filter plate 6, the third filter plate 6 is placed obliquely, which can increase the filtering area of ​​the third filter plate 6 for rainwater on the one hand, and on the other hand, can concentrate the solid waste generated by filtering to the bottom of the drainage trough 3 through gravity.

[0039] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
