Description

Technical Field

[0001] This invention relates to the field of road drainage technology, and more specifically to a road surface water drainage device. Background Technology

[0002] Road surface drainage design is a core component of highway engineering, crucial for removing surface and groundwater and ensuring roadbed stability. It requires considering factors such as highway grade, rainfall, and longitudinal slope, and integrating the roadbed with bridge and culvert structures to form a complete drainage system. Its design objective is to guarantee roadbed and pavement stability and improve road traffic service levels. Road surface drainage is divided into two main categories: surface drainage and subsurface drainage. Surface drainage covers the road surface, shoulders, and median strip, and facilities include side ditches, intercepting ditches, drainage ditches, and storm drains. Subsurface drainage uses infiltration trenches, culverts, and isolation layers to divert water that has seeped into the structure.

[0003] In existing technologies, when installing storm drains on the roadside, a grate (a grid-like structure made up of perpendicular main and secondary reinforcing bars) is typically used to cover the top opening of the storm drain to prevent debris such as fallen leaves and branches from entering. However, in cases of heavy rainfall and road surface flooding, the water flow carries debris towards the grate, causing the grate's openings to become blocked. This necessitates manually disassembling and removing the grate to reopen the storm drain opening, which is quite inconvenient. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a road surface water drainage device to solve the problem that the existing technology requires manual disassembly and removal of the grate when water accumulates on the road surface with heavy rainfall, which is quite troublesome.

[0005] This invention is achieved through the following technical solution:

[0006] A road surface water drainage device includes a rectangular frame, a main rib, and multiple secondary ribs. The multiple secondary ribs are evenly arranged along the width direction of the frame. The two ends of the main rib are fixedly connected to the inner walls of both sides of the frame along the width direction. The multiple secondary ribs are slidably connected to the main rib along the width direction of the frame.

[0007] A rainwater collection basin is provided below the frame. The rainwater collection basin is slidably connected to the frame in the vertical direction, and a drainage hole is provided on the bottom wall of the rainwater collection basin.

[0008] A linkage component is provided between the receiving basin and the multiple secondary ribs. When the receiving basin slides down on the frame, the linkage component drives the multiple secondary ribs to slide and converge.

[0009] Furthermore, the secondary rib has through holes on its sidewall along the width of the frame, and the linkage component includes a pull rope, one end of which is fixedly connected to the receiving basin.

[0010] The other end of the pull rope passes through multiple through holes on multiple secondary reinforcing bars in sequence, and a limiting block is provided at the end, which abuts against the last secondary reinforcing bar.

[0011] Furthermore, a guide hole is provided on the inner side wall of the frame, which connects to the bottom wall of the frame. One end of the pull rope is fixedly connected to the side wall of the container facing the guide hole, and the other end passes through the guide hole and then through multiple through holes in sequence.

[0012] Furthermore, an elastic support is provided between any two adjacent secondary reinforcement bars, and the two ends of the elastic support bar respectively abut against the two corresponding secondary reinforcement bars;

[0013] The multiple elastic support members have the same specifications and dimensions, and in their natural extended state, the first and last secondary ribs abut against the inner walls on both sides of the frame.

[0014] Furthermore, a guide tube is coaxially fixedly connected to one end of the through hole, and the guide tube is sleeved outside the pull rope;

[0015] One end of the guide tube extends out of the through hole and is inserted into the through hole of the adjacent secondary reinforcement, and is in sliding fit.

[0016] Furthermore, the receiving basin is provided with a partition extending along the length of the frame. The height of the top edge of the partition is lower than the height of the top edge of the receiving basin, and the partition divides the inside of the receiving basin into a slag collection chamber and a drainage chamber.

[0017] The slag collection bin is located directly below the last secondary reinforcement, and the drainage bin is located directly below the first secondary reinforcement. Drainage holes are provided on the bottom surfaces of both the slag collection bin and the drainage bin.

[0018] Furthermore, a sliding rod is provided below the main reinforcement bar. One end of the sliding rod is fixedly connected to the bottom surface of the main reinforcement bar, and the other end extends vertically downward through the partition plate and is slidably engaged.

[0019] Furthermore, the diameter of the drainage hole in the slag collection bin is smaller than the diameter of the drainage hole in the drainage bin.

[0020] Furthermore, the main rib has a strip-shaped hole on its side along the length of the frame, and the strip-shaped hole extends toward the width of the frame;

[0021] The secondary rib is embedded in the strip hole in the middle and slides along the width of the frame.

[0022] Furthermore, grooves are provided on the inner walls of both ends of the frame along the length direction, and the grooves extend toward the width direction of the frame;

[0023] The two ends of the secondary rib are respectively inserted into two sliding grooves and are in sliding fit.

[0024] The beneficial effects of this invention are as follows:

[0025] This road surface water drainage device adjusts the width of the gap between adjacent secondary reinforcements by driving the secondary reinforcements to slide on the main reinforcements. It uses a collection basin to collect rainwater passing through the gaps in the secondary reinforcements. When the amount of water discharged from the collection basin is less than the amount of water input, a water storage effect is generated, increasing the overall weight of the collection basin. Under the action of gravity, the collection basin slides downward on the frame, and the linkage component drives multiple secondary reinforcements to automatically slide and converge on the frame, reducing the size of the gap between adjacent secondary reinforcements and increasing the gap between the outer secondary reinforcement and the side wall of the frame. This makes the rainwater well semi-open, promoting drainage without the need for manual operation.

[0026] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0040] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0041] Please see Figure 1-8 The present invention provides a technical solution: a road surface water drainage device, including a rectangular frame 1, a main rib 2 and a plurality of secondary ribs 3, the plurality of secondary ribs 3 being evenly arranged along the width direction of the frame 1, the two ends of the main rib 2 being fixedly connected to the inner walls of both sides of the frame 1 along the width direction, and the plurality of secondary ribs 3 being slidably connected to the main rib 2 along the width direction of the frame 1.

[0042] Below the frame 1, there is a basin 4 for collecting rainwater. The basin 4 is slidably connected to the frame 1 in the vertical direction, and the bottom wall of the basin 4 is provided with a drainage hole 41.

[0043] A linkage component is provided between the receiving basin 4 and the multiple secondary ribs 3. When the receiving basin 4 slides down on the frame 1, the linkage component drives the multiple secondary ribs 3 to slide and gather together.

[0044] In this solution, by driving the secondary reinforcement 3 to slide on the main reinforcement 2, the width of the gap between two adjacent secondary reinforcements 3 can be adjusted. The rainwater passing through the gap of the secondary reinforcement 3 is collected by the collection basin 4. When the amount of water discharged from the collection basin 4 is less than the amount of water input, a water storage effect is generated, increasing the overall weight of the collection basin 4. Under the action of gravity, the collection basin 4 slides downward on the frame 1, and the linkage component drives multiple secondary reinforcements 3 to automatically slide and gather on the frame 1, reducing the size of the gap between two adjacent secondary reinforcements 3 and increasing the gap between the outer secondary reinforcement 3 and the side wall of the frame 1, so that the rainwater well is in a semi-open state, promoting drainage without manual operation.

[0045] The secondary reinforcement 3 is perpendicular to the main reinforcement 2 and is spliced ​​together to form a grid-like structure. The frame 1 is fixedly installed at the opening of the rainwater well to support the main reinforcement 2 and the secondary reinforcement 3. A hole adapted to the main reinforcement 2 can be opened in the middle of the secondary reinforcement 3, and the main reinforcement 2 can be inserted into the hole to achieve a sliding connection. At the same time, the interference fit uses friction to restrict the free sliding of the secondary reinforcement 3.

[0046] The weight of the receiving basin 4 is less than the sum of the frictional forces between the multiple secondary reinforcements 3 and the main reinforcement 2, and less than the weight of the receiving basin 4 filled with water (receiving basin 4 + water).

[0047] The receiving basin 4, when placed on the frame 1, can present the following two states:

[0048] State 1 (e.g.) Figure 3 As shown), the receiving basin 4 is unloaded and in a high position, with multiple secondary reinforcement bars 3 scattered, and the two outer secondary reinforcement bars 3 respectively attached to the inner walls on both sides of the width direction of the receiving basin 4.

[0049] State 2 (e.g.) Figure 5 As shown), the receiving basin is fully loaded and in a low position. Multiple secondary ribs 3 are gathered into a flat plate, which forms one (the flat plate abuts against one side wall of the frame 1) or two (the flat plate is located in the middle of the frame 1) hollow spaces between the flat plate and the frame 1.

[0050] The basin 4 is used to collect rainwater falling from inside the frame 1, and the drain hole 41 at the bottom of the basin 4 is used to drain the rainwater inside the basin 4.

[0051] During use, when there is little rainfall, there is no water accumulation outside the roadside rainwater well. The rainwater that enters the collection basin 4 can be completely discharged from the drainage hole 41. It is difficult to store water and increase weight, so it is in state one and can prevent leaves and branches from passing through.

[0052] When there is a lot of rainfall, the road surface water surrounds or covers the opening of the rainwater well. The rainwater entering the collection basin 4 is difficult to be discharged quickly from the drainage hole 41, resulting in a water storage effect and increased weight. After the collection basin 4 is full of water, it changes from state one to state two. The opening of the rainwater well is semi-open. Fallen leaves, branches and other garbage fall into the collection basin 4 and are collected. The rainwater can overflow the top edge of the collection basin 4 and be discharged, keeping state two stable.

[0053] When the rainfall decreases and the water on the road surface is drained, no new rainwater is injected into the collection basin 4. The rainwater inside is discharged from the drainage hole 41 so that the staff can pick up the collected garbage. After the collection basin 4 is cleaned, the position of the secondary reinforcement 3 is adjusted in preparation for secondary drainage work.

[0054] Therefore, by setting the diameter and number of drainage holes 41, the drainage volume per unit time can be adjusted, the sensitivity of the device can be adjusted, and the usage requirements of different areas (such as differences in precipitation) can be adapted.

[0055] In this embodiment: the secondary rib 3 has a through hole 31 on the side wall along the width direction of the frame 1, and the linkage component includes a pull rope 5, one end of which is fixedly connected to the receiving basin 4.

[0056] The other end of the pull rope 5 passes through multiple through holes 31 on multiple secondary reinforcing bars 3 in sequence, and the end is provided with a limiting block 51, which abuts against the last secondary reinforcing bar 3.

[0057] In this design, a pulley or slide can be installed on the inner wall of the frame 1. The end of the pull rope 5 facing away from the receiving basin 4 is passed around the pulley and then through the through hole 31. The limiting block 51 abuts against the last secondary rib 3. When the receiving basin 4 slides down, the pull rope 5 applies an external force along the width of the frame 1 to the last secondary rib 3 to overcome friction and make it slide. The last secondary rib 3 abuts against the second to last secondary rib 3 and pushes them to slide together until multiple secondary ribs 3 come together and abut against one side wall of the frame 1. A large-sized hollow area is formed on the other side of the frame 1, allowing rainwater, garbage, etc. to pass through smoothly and fall into the receiving basin 4.

[0058] The outer dimensions of the limiting block 51 can be set to be larger than the diameter of the through hole 31, making it difficult for the limiting block 51 to pass through the through hole 31, so that it abuts against the secondary reinforcement 3 and drives the secondary reinforcement 3 to move.

[0059] In this embodiment: a guide hole 11 is provided on an inner side wall of the frame 1, which is connected to the bottom wall of the frame 1. One end of the pull rope 5 is fixedly connected to the side wall of the container 4 facing the guide hole 11, and the other end passes through the guide hole 11 and then passes through multiple through holes 31 in sequence.

[0060] In this design, the guide hole 11 is used to support the middle of the pull rope 5. The opening of the guide hole 11 on the inner side wall of the frame 1 is opposite to the through hole 31 of the secondary rib 3. The pull rope 5 extends out of the guide hole 11 and is taut and parallel to the main rib 2. When the container 4 slides down, the pull rope 5 can apply an external force to the secondary rib 3 in the direction of its sliding, making the secondary rib 3 easier to slide. In state two, multiple secondary ribs 3 converge on the side of the frame 1 with the guide hole 11, so that the other side of the frame 1 is opened to the maximum extent, so that rainwater and garbage can pass through.

[0061] In this embodiment: an elastic support is provided between any two adjacent secondary reinforcement bars 3, and the two ends of the elastic support abut against the corresponding two secondary reinforcement bars 3 respectively;

[0062] The multiple elastic support members have the same specifications and dimensions, and in their natural extended state, the first secondary rib 3 and the last secondary rib 3 abut against the inner walls on both sides of the frame 1.

[0063] In this design, the elastic support is a compression spring 6, which is sleeved on the outside of the pull rope 5, and its two ends are respectively connected to two adjacent secondary ribs 3. Since the specifications and dimensions of the multiple compression springs 6 are the same, in state one, all the compression springs 6 are in a compressed state, and the gap size between any two adjacent secondary ribs 3 is equal.

[0064] When transitioning from state one to state two, multiple secondary ribs 3 slide and converge synchronously, causing multiple compression springs 6 to deform and contract to store energy. As the water in the water storage basin gradually decreases, multiple compression springs 6 can simultaneously release energy to push the secondary ribs 3 to slide and reset until they return to the initial (state one) position.

[0065] Therefore, when the water storage basin is storing water, the multiple secondary ribs 3 automatically converge to promote drainage; when the water storage basin is draining water, the multiple secondary ribs 3 automatically disperse to prevent garbage from passing through.

[0066] In this embodiment: a guide tube 32 is coaxially fixedly connected to one end of the through hole 31, and the guide tube 32 is sleeved on the outside of the pull rope 5;

[0067] One end of the guide tube 32 extends out of the through hole 31 and is inserted into the through hole 31 of the adjacent secondary rib 3, and is slidably fitted.

[0068] In this scheme, in state one, the guide tube 32 is inserted into the through hole 31 of the adjacent secondary rib 3 at one end outside the corresponding through hole 31, guiding the sliding of the two adjacent secondary ribs 3. The outer wall of the guide tube 32 can be sealed to the through hole 31 to reduce or prevent rainwater from entering the through hole 31 and causing corrosion damage to the pull rope 5. The shape of the limiting block 51 is adapted to the through hole 31. The limiting block 51 is embedded in the through hole 31 of the last secondary rib 3 and abuts against the guide tube 32 on the secondary rib 3, so that a section of the pull rope 5 within the multiple secondary ribs 3 is in a relatively sealed environment, which protects against tension.

[0069] The compression spring 6 is installed inside the through hole 31, and its two ends are respectively opposed to the two guide tubes 32, so that the corresponding two secondary ribs 3 tend to keep away from each other. The compression spring 6 is in a relatively closed environment and is not easily corroded or damaged by rainwater.

[0070] In this embodiment: a partition 42 extending along the length of the frame 1 is provided inside the receiving basin 4. The height of the top edge of the partition 42 is lower than the height of the top edge of the receiving basin 4, and the partition 42 divides the inside of the receiving basin 4 into a slag collection chamber 43 and a drainage chamber 44.

[0071] The slag collection bin 43 is located directly below the last secondary reinforcement 3, and the drainage bin 44 is located directly below the first secondary reinforcement 3. Drainage holes 41 are provided on the bottom surfaces of both the slag collection bin 43 and the drainage bin 44.

[0072] In this scheme, the height of the partition 42 is lower than the height of the top edge of the receiving basin 4. In state two, multiple secondary ribs 3 gather and block above the drainage chamber 44, restricting rainwater from passing through and falling into the drainage hole 41. The top of the slag collection chamber 43 is open, allowing rainwater and garbage to fall smoothly into the slag collection chamber 43 for initial garbage collection, causing most of the garbage to sink to the bottom of the slag collection chamber 43. When the drainage hole 41 in the slag collection chamber 43 is blocked by garbage, or when the water inflow is too large, rainwater and a small amount of garbage can overflow the top edge of the partition 42 and enter the drainage chamber 44. After being filtered by the drainage hole 41 in the drainage chamber 44, the garbage is collected a second time, reducing the probability of garbage entering the rainwater well.

[0073] Furthermore, most of the trash is collected below the open side of frame 1 for easy retrieval and unblocking.

[0074] In this embodiment: a sliding rod 21 is provided below the main rib 2. One end of the sliding rod 21 is fixedly connected to the bottom surface of the main rib 2, and the other end extends vertically downward through the partition plate 42 and is slidably engaged.

[0075] In this scheme, there are two main ribs 2, and each main rib 2 is equipped with a sliding rod 21. Both sliding rods 21 pass through the partition 42 and are slidably engaged, so that the receiving basin can only slide on the frame 1 in the vertical direction (sliding rod 21).

[0076] In this embodiment, the diameter of the drainage hole 41 inside the slag collection bin 43 is smaller than the diameter of the drainage hole 41 inside the drainage bin 44.

[0077] In this design, the number of drainage holes 41 inside the slag collection bin 43 is less than the number of drainage holes 41 inside the drainage bin 44. This ensures that the slag collection bin 43 primarily functions to filter and collect garbage, while also maintaining a certain water storage capacity. Rainwater is mainly discharged through the drainage holes 41 inside the drainage bin 44, and drainage holes 41 are also provided on the side wall of the drainage bin 44 to improve drainage capacity and reduce the probability of rainwater overflowing from the top edge of the collecting basin 4, thus ensuring sufficient garbage collection.

[0078] In this embodiment: the main rib 2 has a strip hole 22 on its side along the length direction of the frame 1, and the strip hole 22 extends toward the width direction of the frame 1;

[0079] The secondary rib 3 is embedded in the strip hole 22 in the middle and slides along the width direction of the frame 1.

[0080] In this design, the main reinforcement 2 supports the secondary reinforcement 3. The secondary reinforcement 3 has a notch at the same location as the main reinforcement 2. After the secondary reinforcement 3 is inserted into the strip hole 22, the two side walls of the notch are respectively attached to the two side walls of the main reinforcement 2 along the length direction of the frame 1, so that the secondary reinforcement 3 can only slide on the main reinforcement 2 along the length direction of the main reinforcement 2 (the width direction of the frame 1).

[0081] In this embodiment: the inner walls at both ends of the frame 1 along the length direction are provided with grooves 12, and the grooves 12 extend toward the width direction of the frame 1;

[0082] The two ends of the secondary rib 3 are respectively inserted into the two sliding grooves 12 and are in sliding fit.

[0083] In this design, the two ends of the secondary rib 3 are inserted into the two sliding grooves 12 on the frame 1, and the frame 1 supports the two ends of the secondary rib 3. The main rib 2 supports the middle of the secondary rib 3, making the overall structure of the device more compact and stable.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
