Description

Technical Field

[0001] This utility model relates to the field of road rainwater harvesting technology, and in particular to a rainwater harvesting structure for municipal roads. Background Technology

[0002] my country has a large number of municipal roads, large and small, that are intertwined. When rainwater falls on the roads, it can only be discharged by the city's drainage system. In response to this situation, various rainwater harvesting devices have emerged on the market. These devices usually include a rainwater collection chamber and a grate. Although they can meet the needs of rainwater collection, they also have some drawbacks.

[0003] Chinese utility model patent application number 202220510766.4 discloses a rainwater harvesting structure for municipal roads, comprising a main body; the main body includes a first plane parallel to the road surface and a second plane in contact with the road cross-section; the first plane is provided with filter holes for filtering impurities; a collection chamber is provided inside the main body, and the filter holes and the collection chamber are interconnected; the second plane is inclined and has rollers for moving the main body; the main body is provided with a pull buckle for pulling the main body along the road cross-section. In this utility model, the side in contact with the road end face is an inclined plane, and rollers are provided on this surface. When the main body is lowered into or removed from the road surface, it can be moved slowly by the rollers, which is very convenient. In addition, the main body has a pull-out filter frame containing loose sand, which can filter out fine solid particles in the rainwater, ensuring the cleanliness of the collected rainwater and avoiding subsequent impact on the suction pump.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist:

[0005] During the cleaning process, the entire device needs to be removed before the internal pull-out filter can be taken out, which makes the overall operation time-consuming and labor-intensive, causing inconvenience to cleaning and maintenance. In addition, rainwater harvesting devices are usually located on municipal roads, and each one needs to be removed before cleaning. After cleaning, they also need to be reinstalled, which is too much work and too costly, making it difficult to promote and use. Utility Model Content

[0006] To address the technical problems of inconvenient cleaning and maintenance, excessive workload, and unfavorable promotion and use of existing municipal road rainwater harvesting devices, this utility model provides a municipal road rainwater harvesting structure.

[0007] This utility model is achieved using the following technical solution: a municipal road rainwater harvesting structure, comprising:

[0008] The main body is composed of an upper shell and a lower shell;

Sliding blocks are inserted and slidably connected inside the two slide bars. Filter plate two is fixedly connected to the middle of each of the two sliding blocks. The sieve hole diameter of filter plate two is smaller than that of filter plate one, and the sieve hole diameter of filter plate two is smaller than that of the well cover sieve hole.

[0012] As a further improvement to the above solution, an inlet and an outlet are sequentially provided on both sides of the bottom end of the lower shell, and the vertical height of the inlet is higher than that of the outlet, with the rainwater flowing from the inlet to the outlet.

[0013] As a further improvement to the above solution, vertical rods are symmetrically fixedly connected to the inner wall of the upper shell, and the vertical rods are set perpendicular to the direction of rainwater flow. The vertical rods are slidably connected to both sides of the filter plate. Side rods are fixedly connected to the inner wall of the upper shell at the point where they are aligned with the direction of rainwater flow. The side rods are slid perpendicularly to the filter plate. Rubber blocks are provided at the connection points between the filter plate and the side rods and the vertical rods.

[0014] As a further improvement to the above solution, grooves are evenly provided on the inner sides of both side rods, and the two grooves are asymmetrically arranged.

[0015] As a further improvement to the above solution, the two sides of the filter plate slidably abut against the grooves on both sides, so that the filter plate 2 slides horizontally back and forth at the bottom of the filter plate 1, and the bottom ends of the filter plate 2 are symmetrically fixed with handles.

[0016] As a further improvement to the above solution, the limiting component includes a slot opened in the middle of one side of the manhole cover, a limiting rotating block inserted into the slot, the limiting rotating block rotating on one side of the top of the upper housing, and a locking hole opened on the top of the limiting rotating block.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example 1:

[0030] Please combine Figures 1-5 This embodiment of a municipal road rainwater harvesting structure includes:

[0031] The main body consists of an upper shell 1 and a lower shell 2. The upper shell 1 is located at the top and is used to receive rainwater from the top. The lower shell 2 guides the rainwater to the collection area. The lower shell 2 is designed to gradually decrease in width from the top to the bottom.

[0032] The manhole cover 5 is hinged to one side of the upper housing 1. The manhole cover 5 and the upper housing 1 are provided with a limiting component on the other side. The manhole cover 5 is locked to the upper housing 1 by the limiting component to prevent it from being opened and disassembled by others at will.

[0033] The filter element is vertically movable inside the upper housing 1, making it easy to remove and clean.

[0034] The filter element includes a filter plate 14, with slide bars 15 symmetrically fixed to the bottom of the filter plate 14. Sliding blocks 16 are inserted and slidably connected inside the two slide bars 15. Filter plate 17 is fixedly connected to the middle of each of the two sliding blocks 16. The sieve aperture of filter plate 17 is smaller than that of filter plate 14, and the sieve aperture of filter plate 17 is smaller than that of the 5-sieve aperture of the manhole cover. This is used to gradually filter rainwater in multiple layers to ensure that the collected rainwater has fewer impurities.

[0035] The bottom of the lower housing 2 is provided with an inlet 3 and an outlet 4 on both sides in sequence. The vertical height of the inlet 3 is higher than that of the outlet 4. Specifically, the inlet 3 is slightly inclined downward from the outlet 4 to the outlet 4. The rainwater flows from the inlet 3 to the outlet 4. The inlet 3 is recessed and the outlet 4 is protruding. The outlet 4 in another set of devices can be plugged into the inlet 3 of this set to achieve assembly and connection.

[0036] Vertical rods 11 are symmetrically fixed to the inner wall of the upper shell 1, and the vertical rods 11 are set perpendicular to the direction of rainwater flow. The vertical rods 11 are slidably connected to both sides of the filter plate 14. A side rod 12 is fixed to the inner wall of the upper shell 1 at the position consistent with the direction of rainwater flow. The side rod 12 slides perpendicularly to the filter plate 14. Rubber blocks are provided at the connection points of the filter plate 14 with the side rod 12 and the vertical rod 11. The rubber blocks have a large resistance when connected to the vertical rod 11 and the side rod 12. They will slowly descend under the influence of gravity and rainwater erosion during subsequent use until they fall into the connection point between the upper shell 1 and the lower shell 2.

[0037] The limiting component includes a slot 6 located in the middle of one side of the manhole cover 5. A limiting rotating block 10 is inserted into the slot 6. The limiting rotating block 10 rotates to one side of the top of the upper housing 1. A locking hole 9 is provided at the top of the limiting rotating block 10. The top of the locking hole 9 has a special structure that requires a special workpiece to open.

[0038] The top of the upper shell 1 has a sloping surface 7, which abuts against a sloping surface 8. The sloping surface 8 is located at the bottom of the manhole cover 5. The sloping surface 7 and the sloping surface 8 match each other so that they fit together more closely when closed.

[0039] The implementation principle of a municipal road rainwater harvesting structure in this application embodiment is as follows:

[0040] After the multiple devices are installed and assembled, the filter components are installed and placed in the upper housing 1 in sequence, and the hinged well cover 5 is flipped and closed. The workpiece is used to rotate the lock hole 9 to realize the limit block 10 to limit the insertion of the slot 6.

[0041] When it rains, the rainwater will first pass through the screen holes of the manhole cover 5 to filter out larger debris, allowing the rainwater to gradually enter the upper shell 1 through other screen holes, and then fall into the bottom of the lower shell 2 through the first filter plate 14 and the second filter plate 17, and flow towards the outlet 4.

[0042] When cleaning regularly, simply open the manhole cover 5 and lift the internal filter plate 14 vertically to clean it; there is no need to remove the entire device.

[0043] Example 2:

[0044] Combination Figure 2 , Figure 4 and Figure 5 This embodiment is an improvement on embodiment 1, further described in the following aspects:

[0045] Both side rods 12 have grooves 13 evenly distributed on their inner sides, and the two grooves 13 are asymmetrically arranged.

[0046] The two sides of the filter plate 17 slide against the grooves 13 on both sides in sequence, so that the filter plate 17 slides horizontally back and forth at the bottom of the filter plate 14. The two bottom ends of the filter plate 17 are symmetrically fixed with handles 18.

[0047] The implementation principle of this embodiment is as follows:

[0048] Because the filter plate 14 is connected to the vertical rod 11 and the side rod 12 by rubber, which generates a large friction force, the filter plate 14 can maintain its relative height to the upper shell 1 without external force. When it rains, the rainwater enters and brings an impact force to the filter plate 14. Under the weight of the rainwater itself, the entire filter plate 14 moves vertically downward along the vertical rod 11 and the side rod 12. As the filter plate 14 drives the filter plate 2 17 to slide down, the filter plate 2 17 will slide horizontally back and forth at the bottom of the filter plate 14 under the action of the grooves 13 on both sides, which slide and abut against each other. This can shake the rainwater at the filter plate 2 17 and prevent it from being blocked by impurities.

[0049] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
