Description

Technical Field

[0001] This invention relates to the field of prefabricated paving technology, and in particular to an environmentally friendly and eco-friendly prefabricated pedestrian paving. Background Technology

[0002] In the field of environmentally friendly prefabricated pedestrian paving, although existing modular paving panels have achieved rapid assembly and ecological function integration, the following easily overlooked technical problems still exist: First, the potential for stress concentration under temperature-induced deformation. When the ambient temperature fluctuates significantly, the linear deformation caused by thermal expansion and contraction of the paving panel modules can easily lead to stress concentration at traditional rigid connection points between modules (such as ordinary tenons and buckles). Over time, this can cause cracking and damage at the edges of the modules, severely reducing the structural durability of the paving system. Second, the hidden blockage and cleaning difficulties of permeable holes. Small particles carried by pedestrians pose a challenge. Debris (such as leaf particles and sandy dust) tends to accumulate gradually in the permeable holes of the paving slab. Traditional permeable holes lack a convenient mechanical self-cleaning mechanism. Manual cleaning requires disassembling the module, which is cumbersome and can easily damage the integrity of the paving. Long-term blockage will significantly weaken the permeability and water storage capacity of the paving. Thirdly, there is the risk of water seepage and erosion from the anti-slip texture. The surface texture designed to improve anti-slip performance can easily seep into the bonding surface between the paving slab and the base layer during cleaning (such as high-pressure water jet washing) or natural rainfall. Long-term water accumulation will erode the base structure and further affect the overall stability of the paving system. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention is proposed.

[0005] The cleaning component includes an assembly block, the inner wall of which is provided with an installation sleeve and the installation sleeve is provided with a pushing component, the pushing component including floating protrusions and the floating protrusions moving on the inner wall of the installation sleeve due to the influence of pedestrian walking.

[0006] The end of the pusher is connected to a moving part, and the moving part includes a paddle disposed on the inner wall of the cleaning hole on the end face of the assembly block. When the floating protrusion moves down the inner wall of the mounting sleeve, it cleans the inner wall of the cleaning hole through the paddle.

[0007] As a preferred embodiment of the environmentally friendly prefabricated pedestrian paving slab of the present invention, the end face of the assembly block is further provided with a connecting groove and the connecting groove is connected to the drainage groove, and the end of the cleaning hole is further provided with an inlet and the inlet is located on the inner wall of the connecting groove.

[0009] As a preferred embodiment of the environmentally friendly prefabricated pedestrian paving slab of the present invention, wherein: the outer wall of the rack is further sleeved with a third elastic element and the third elastic element is disposed on the inner wall of the mounting sleeve.

[0010] As a preferred embodiment of the environmentally friendly prefabricated pedestrian paving slab of the present invention, the moving part includes a gear and the outer wall of the gear meshes with the rack through an opening provided on the outer wall of the mounting sleeve.

[0011] As a preferred embodiment of the environmentally friendly prefabricated pedestrian paving slab of the present invention, wherein: a first joint is provided at the gear shaft and the first joint is also connected to a universal connecting shaft, and the other end of the universal connecting shaft is connected to a second joint, and the outer wall of the second joint is provided with a dial.

[0013] As a preferred embodiment of the environmentally friendly prefabricated pedestrian paving slab of the present invention, the end face of the assembly block is further provided with an installation hole, the inner wall of the installation hole is provided with a slide rail and a limiting groove, the end of the slide rail is connected to the end of the limiting groove, and the end face of the installation hole is provided with a cover.

[0014] As a preferred embodiment of the environmentally friendly prefabricated pedestrian paving slab of the present invention, the outer wall of the paving slab is provided with a concave platform and a convex platform, the end face of the concave platform is provided with a tenon groove, and the outer wall of the convex platform is provided with a tenon.

Combined with the sliding track and limiting groove design of the installation hole, the assembly block can be accurately positioned and quickly fixed without additional measuring tools. The cover can also block the installation hole to prevent rainwater intrusion, which greatly improves construction efficiency and extends the life of the components. The cleaning system relies on the natural kinetic energy of pedestrians to drive the floating protrusions. The rack, gear and universal connecting shaft drive the paddle to rotate in both directions. Combined with the vortex flushing formed by rainwater through the diversion channel and the inlet, the deep cleaning of the inner wall of the cleaning hole can be completed without external power. It effectively avoids the blockage of sand and debris. Moreover, the sewage can be discharged in an orderly manner or infiltrated to replenish the groundwater, which meets the ecological needs.

[0017] Meanwhile, the paving panels are connected by elastic tenon and mortise joints with movable top blocks. The movable top blocks achieve axial expansion and contraction through double elastic elements. Unlike traditional rigid structures, this can disperse stress when the panel deforms due to temperature differences, avoid cracking at the edge of the module, ensure connection stability, and adapt to paving needs in different climatic environments.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0031] Reference Figures 1-4 This is the first embodiment of the present invention, which provides an environmentally friendly and ecological prefabricated pedestrian paving slab.

[0032] Specifically, the main component 100 includes a paving plate 101. The paving plate 101 has a guide groove 102 and a drainage groove 103 at its end. The guide groove 102 has a guide groove 1021 on its outer wall and the end of the guide groove 1021 is connected to a drainage groove 1022.

[0033] Cleaning component 200 includes assembly block 201. The inner wall of assembly block 201 is provided with mounting sleeve 202 and the mounting sleeve 202 is provided with a pusher. The pusher includes floating protrusion 203 and the floating protrusion 203 moves on the inner wall of mounting sleeve 202 due to the influence of pedestrian walking.

[0034] The end of the pusher is connected to a moving part, and the moving part includes a paddle 2044 disposed on the inner wall of the cleaning hole 2014 on the end face of the assembly block 201. When the inner wall of the mounting sleeve 202 moves down, the floating protrusion 203 cleans the inner wall of the cleaning hole 2014 through the paddle 2044.

[0035] This application applies to public areas such as urban sidewalks, community trails, park landscape paths, and bus stops that use prefabricated paving, and is especially suitable for rainy areas or ecological paving scenarios with high pedestrian traffic.

[0036] In urban sidewalks, park trails, and other similar applications, when encountering natural rainfall or when the paved surface needs to be manually washed with a high-pressure water gun, the water flow will naturally converge along the surface texture of the paving slab 101. Because the pre-set guide groove 102 at the end of the paving slab 101 has an inverted trapezoidal structure that is wider at the top and narrower at the bottom, and the groove opening is slightly lower than the surface of the paving slab, the water flow will quickly flow into the guide groove 102, effectively preventing water accumulation on the paved surface. The guide grooves 1021 on the outer wall of the guide groove 102 are distributed in a "branching" pattern, which can further divert and guide the water flow within the groove. Some of the water flows directly to the drainage groove 103 at the edge of the paving slab, while the other part of the water flows into the drainage trough 1022 through the connecting port at the end of the guide groove 1021.

[0037] When pedestrians walk, they naturally step on the raised structures on the surface of the paving slab 101, most of which are fixed protrusions 1011, and a small portion are floating protrusions 203 that are adapted to the assembly block 201. When a pedestrian's foot contacts and applies pressure to the floating protrusion 203, the floating protrusion 203 is subjected to axial pressure and moves vertically downward smoothly along the mounting sleeve 202 preset on the inner wall of the assembly block 201. Since the floating protrusion 203 acts as a pushing component and is directly connected to the moving component at the bottom, its downward movement synchronously drives the moving component to start transmission.

[0038] As the moving parts are triggered, the paddle 2044 installed on the inner wall of the cleaning hole 2014 on the end face of the assembly block 201 will rotate in a circular motion with the power output of the moving parts. As the core permeable channel of the paving plate 101, the cleaning hole 2014 is easily blocked by small debris such as sand dust, fallen leaves, and pet hair carried by pedestrians during daily use. The rotation trajectory of the paddle 2044 is closely attached to the inner wall of the cleaning hole 2014, which can directly scrape off the debris attached to the hole wall.

[0039] While the rotating blade 2044 scrapes away debris, rainwater or flushing water stored in the drainage channel 1022 continuously flows into the cleaning hole 2014 area. The water flow and the rotating blade 2044 form a vortex flush, which not only thoroughly washes away the debris scraped off by the blade 2044 from the hole wall, but also performs a secondary cleaning of fine dust in the gaps inside the hole. After cleaning, the wastewater flows downward along the channel of the cleaning hole 2014 and is discharged, achieving orderly discharge of wastewater or natural infiltration of rainwater to replenish groundwater. Example 2

[0040] Reference Figures 4-7 This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0041] Specifically, the end face of the assembly block 201 is also provided with a connecting groove 2012 and the connecting groove 2012 is connected to the drainage groove 1022. The end of the cleaning hole 2014 is also provided with an inlet 2013 and the inlet 2013 is located on the inner wall of the connecting groove 2012.

[0042] The two ends of the connecting groove 2012 on the surface of the assembly block 201 are connected to the two ends of the drainage groove 1022. After the flushing water or rainwater enters the drainage groove 1022 from the guide groove 102, it flows through the connecting groove 2012, and a part of it gathers in the inlet 2013 and flows downward along the inlet 2013.

[0043] Preferably, the floating protrusion 203 is provided with a column 2031 at its end and a rack 2033 at its end. The outer wall of the column 2031 is provided with a protrusion 2032 and the end of the protrusion 2032 extends to the inner wall of the groove 2021 opened on the outer wall of the mounting sleeve 202. The outer wall of the rack 2033 is also provided with a third elastic element 2034 and the third elastic element 2034 is provided on the inner wall of the mounting sleeve 202.

[0044] The mounting sleeve 202 is fixed inside the assembly block 201, and the column 2031 is fixed at the axis of the lower surface of the floating protrusion 203 and is fixedly connected to the floating protrusion 203. When the floating protrusion 203 is stepped on by a pedestrian, it causes the column 2031 to move downward inside the mounting sleeve 202, and the rack 2033 below moves downward synchronously.

[0045] The protruding post 2032 moves synchronously with the upright post 2031. When it moves downward, it presses the third elastic element 2034 on the inner wall of the mounting sleeve 202 to move downward. After the pedestrian moves away, it is pushed back up by the third elastic element 2034, so that the floating protrusion 203 is reset.

[0046] The moving part includes a gear 204, and the outer wall of the gear 204 meshes with a rack 2033 through an opening 2022 on the outer wall of the mounting sleeve 202. A first connector 2041 is provided at the shaft center of the gear 204, and the first connector 2041 is also connected to a universal connecting shaft 2042. The other end of the universal connecting shaft 2042 is connected to a second connector 2043, and the outer wall of the second connector 2043 is provided with an array of paddles 2044.

[0047] The gear 204 is installed inside the assembly block 201. The outer wall of the gear 204 meshes with the rack 2033 inside the mounting sleeve 202 through the opening 2022. When the rack 2033 moves down with the floating protrusion 203, it drives the gear 204 to rotate.

[0048] The paddle 2044 is installed on the outside of the connecting rod at the shaft of the second connector 2043. The outer wall of the paddle 2044 is not in complete contact with the inner wall of the cleaning hole 2014. When the gear 204 rotates, it is connected to the universal joint shaft 2042 through the first connector 2041, and drives the second connector 2043 and the paddle 2044 on its surface to rotate synchronously. When the floating protrusion 203 is reset, it drives the paddle 2044 to reverse inside the cleaning hole 2014, and performs secondary cleaning on the inside of the cleaning hole 2014. This is combined with the rainwater or flushing water flowing through the inlet 2013 to clean the inner wall of the cleaning hole 2014.

[0049] The end of the paving plate 101 is provided with an installation groove 104 and the inner wall of the installation groove 104 is provided with a limiting guide rail 1041. The outer wall of the assembly block 201 is provided with a vertical groove 2011 and the outer wall of the limiting guide rail 1041 extends to the inner wall of the vertical groove 2011 and slides with it.

[0050] The vertical grooves 2011 symmetrically opened on the outer wall of the assembly block 201 are opposite to the limiting guide rails 1041 on the inner wall of the mounting groove 104. When the assembly block 201 is installed into the mounting groove 104, it is fully installed and lowered by aligning the vertical grooves 2011 with the limiting guide rails 1041.

[0051] Preferably, the end face of the assembly block 201 is also provided with a mounting hole 2015, the inner wall of the mounting hole 2015 is provided with a slide 2016 and a limiting groove 2017, the slide 2016 is connected to the end of the limiting groove 2017, and a cover 2018 is provided on the end face of the mounting hole 2015.

[0052] The mounting holes 2015 are symmetrically opened on the upper surface of the assembly block 201, and the inner wall is provided with a slide rail 2016. When installing the assembly block 201, a tool is inserted into the mounting hole 2015. The outer wall of the tool has a protrusion that aligns with the slide rail 2016. After it is fully inserted into the mounting hole 2015, the tool is rotated so that the protrusion on the outer wall of the tool aligns with the bottom limiting groove 2017 and the tool is engaged in the mounting hole 2015, so as to complete the installation of the assembly block 201.

[0053] After installation, the cover 2018 is placed above the mounting hole 2015 to prevent rainwater from entering.

[0054] In summary, during use, the inner wall of the mounting groove 104 at the end of the paving plate 101 is pre-set with a limiting guide rail 1041, and the vertical grooves 2011 symmetrically opened on the outer wall of the assembly block 201 are aligned with the limiting guide rail 1041 during installation. They can be directly aligned visually without the need for additional measuring tools, and the initial positioning of the assembly block can be completed quickly.

[0055] Insert the tip of the assembly tool into the mounting hole 2015 on the upper surface of the assembly block 201, so that the tool protrusion extends vertically along the slide 2016 on the inner wall; after reaching the bottom of the hole, rotate the tool so that the protrusion is engaged in the limiting groove 2017 that communicates with the slide. Then install the assembly block 201 smoothly down to the bottom of the mounting groove 104 along the limiting guide rail 1041 to complete the fixing. After the installation is completed, fasten the cover 2018 to the top of the mounting hole 2015 to completely seal the hole.

[0056] During natural rainfall or artificial washing of the paved surface, rainwater / washing water converges along the surface of the paved slab 101 to the end guide channel 102. After being diverted by the guide channel 102, part of the water flows directly into the drainage channel 103 and is discharged through the drain outlet 1031 at the top of the drainage channel 103. The other part of the water flows into the guide channel 1021 on the outer wall of the guide channel 102. The guide channel 1021 guides the water flow into the drainage channel 1022. Since the two ends of the connecting groove 2012 on the end face of the assembly block 201 are connected to the drainage channel 1022, the water in the drainage channel 1022 will naturally flow into the connecting groove 2012 and be distributed along the channel.

[0057] The inlet 2013 on the inner wall of the connecting tank 2012 can quickly gather the water flow in the tank, so that the water flows vertically downward along the inlet 2013 into the top area of ​​the cleaning hole 2014, completing the pre-reservation of clean water source.

[0058] When a pedestrian walks on the paved surface, the pedestrian's foot steps on the floating protrusions 203 on the surface of the assembly block 201. The protrusions are driven by axial pressure to move the column 2031 at the bottom axis vertically downward along the inner wall of the mounting sleeve 202. The protrusions 2032 on the outer wall of the column 2031 slide along the groove 2021 on the outer wall of the mounting sleeve, providing guidance and limiting for the column 2031.

[0059] When the column 2031 moves down, the rack 2033 at its end moves down synchronously, and the third elastic element 2034 on the outer wall of the rack 2033 is squeezed and deformed to store energy; at the same time, the rack 2033 meshes with the gear 204 inside the assembly block through the opening 2022 on the outer wall of the mounting sleeve 202, driving the gear 204 to rotate clockwise along the axis.

[0060] When gear 204 rotates, the first joint 2041 at its shaft center drives the universal joint shaft 2042 to rotate synchronously. The universal joint shaft 2042 transmits power to the cleaning hole 2014 through the second joint 2043 at the other end, driving the paddles 2044 arrayed on the outer wall of the second joint 2043 to rotate clockwise.

[0061] When the paddle 2044 rotates clockwise, its edge maintains a 1-2mm gap with the inner wall of the cleaning hole 2014, which avoids wear caused by hard friction and effectively scrapes off sand, dust, leaf debris and other debris attached to the hole wall; at the same time, the water flow gathered at the inlet 2013 flows down along the inner wall of the cleaning hole 2014, forming a "vortex flushing effect" with the rotating paddle 2044, which completely peels off the scraped debris from the hole wall;

[0062] When the pedestrian's foot leaves the floating protrusion 203, the third elastic element 2034 releases its stored energy, pushing the rack 2033, column 2031 and floating protrusion 203 to return to their original position. When the rack 2033 moves upward, it drives the gear 204 to rotate counterclockwise, which drives the paddle 2044 to rotate in the opposite direction through the universal joint shaft 2042, performing a secondary scraping on the inner wall of the cleaning hole 2014 to further clean the fine impurities remaining from the forward cleaning.

[0063] The mixture of "debris and sewage" generated during cleaning is discharged along the bottom of the cleaning hole 2014 and eventually flows into the municipal pipe network or underground infiltration layer. Example 3

[0064] Reference Figures 1-4 This is the third embodiment of the present invention, which is implemented based on the previous embodiment.

[0065] Specifically, the outer wall of the paving slab 101 is provided with a recessed platform 1012 and a protruding platform 1013. The end face of the recessed platform 1012 is provided with a tenon 1014, and the outer wall of the protruding platform 1013 is provided with a tenon 1015.

[0066] The outer wall of the paving slab 101 has a recessed platform 1012 on one side and a protrusion 1013 on the other side. During the installation process, the protrusion 1013 on the outer wall of the paving slab 101 cooperates with the recessed platform 1012 on the outer wall of the adjacent paving slab 101. The installation is completed by the cooperation of the tenon 1015 on the outer wall of the protrusion 1013 and the mortise 1014 on the surface of the recessed platform 1012. The paving slabs are then arranged and laid out in this manner.

[0067] Preferably, a movable top block 1016 is fitted on the outer wall of the tenon 1015, a connecting shaft 1017 is provided on the inner wall of the movable top block 1016 and the end of the connecting shaft 1017 extends to the inner wall of the tenon 1015, a first elastic element 1018 is fitted on the outer wall of the connecting shaft 1017, and a second elastic element 1019 is also provided at the end of the connecting shaft 1017.

[0068] The movable top block 1016 is installed at the top of the tenon 1015. During installation, the movable top block 1016 is pressed against the inner wall of the mortise 1014 and can extend and retract at the top of the tenon 1015 and slide on the inner wall of the mortise 1014 through the first elastic element 1018 on the outer wall of the connecting shaft 1017 and the second elastic element 1019 on the side.

[0069] Unlike traditional rigid mortise and tenon structures, in this application, the stress is dispersed into the material through the axial elastic displacement of the movable top block 1016. When the temperature difference causes the plate to deform, the movable top block 1016 slides and expands with the elastic element in the buffer cavity, dispersing the stress and preventing edge cracking, thus ensuring the stability of the module connection and avoiding edge cracking.

[0070] 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.
