Description

Technical Field

[0001] This utility model relates to the field of municipal and garden drainage, and in particular to a municipal and garden drainage ditch. Background Technology

[0002] Open ditch drainage systems, as a crucial drainage structure, are widely used in various locations such as roads, squares, gardens, and residential areas. Their main function is to quickly remove surface water, keep the site dry, and ensure pedestrian safety. Currently, most common open ditch drainage structures on the market adopt symmetrical forms and flat-bottomed waterway designs. When faced with water containing a lot of sand or debris, they often suffer from problems such as easy clogging and reduced drainage efficiency.

[0003] To solve the above-mentioned technical problems, an open ditch drainage structure has been proposed in the prior art, such as Chinese Patent No. CN223256163U. This utility model is designed with a higher slope on one side of the waterway and a lower slope on the other side, forming a natural inclination. It uses gravity to cause heavy objects such as sand and gravel in the water flow to be deposited along the higher slope side, effectively preventing debris from clogging the waterway.

[0004] However, existing technologies similar to the aforementioned patents have the following problems: larger foreign objects such as sand and leaves still accumulate at lower levels, affecting the flow rate of water or causing blockages in the channel. If it is necessary to clean the lower levels, personnel need to use tools or their bare hands to reach deep into the bottom of the channel to clean it, which is very inconvenient.

[0005] Therefore, there is an urgent need for a municipal garden drainage system that can solve the above-mentioned technical problems. Utility Model Content

[0006] To address the problem of inconvenient cleaning of existing municipal and garden drainage ditches, this utility model proposes a municipal and garden drainage ditches, the technical solution of which is as follows:

[0007] A municipal garden drainage ditch includes a straight channel with a cover on top. One side of the cover is a hinged side, which is hinged to one edge of the channel opening. The other side of the cover is a movable side, which is movably attached to the opposite side of the channel opening.

[0008] A filter plate is provided at the bottom of the channel below the cover. A guide mechanism is provided between the filter plate and the side wall of the channel. The guide mechanism restricts the filter plate to move only along the side wall of the channel and in a direction perpendicular to the axis of the channel.

[0009] A linkage mechanism is connected between the filter plate and the cover. The linkage mechanism includes several parallel connecting rods. One end of each connecting rod is rotatably connected to the side of the filter plate near the guide mechanism, and the other end is rotatably connected to the bottom surface of the cover near the movable side. The connecting rod is perpendicular to the axis of the channel.

[0010] Furthermore, the cover is a rectangular plate with several drainage holes.

[0011] Furthermore, the guiding mechanism includes a guide rail disposed on the side wall of the channel, and the axis of the guide rail is perpendicular to the channel axis. It also includes a guide block slidably disposed on the guide rail, the guide block being movable along the axis of the guide rail, and the side of the guide block away from the guide rail being fixedly connected to the outer periphery of the filter plate.

[0012] Furthermore, the guide rail is a rectangular column that is fitted and fixed to the side wall of the channel. The rectangular column has grooves on both sides along its own axis. The axial cross section of the groove is semi-circular. Multiple pairs of pulleys are installed on both sides of the guide block along its own movement direction. The rolling direction of the pulleys is parallel to the axis of the groove. When the guide block is slidably set on the guide rail, each pair of pulleys is symmetrically located in the grooves on both sides of the guide rail, and the pulleys abut against the bottom of the groove.

[0013] Furthermore, the bottom surface of the cover near the movable side is provided with multiple pairs of hinge ears, and the filter plate near the guide rail is also provided with multiple pairs of hinge ears. A hinge shaft is provided in the hinge ear, the axis of the hinge shaft is parallel to the channel axis, and hinge holes are opened at both ends of the connecting rod. The connecting rod is hinged to the hinge shaft through the hinge holes at both ends.

[0014] Furthermore, the filter plate curves upward on both sides along the channel axis, and several isolation plates perpendicular to the channel axis are vertically arranged on the filter plate. Several filter holes are opened on both the isolation plates and the filter plate.

[0015] Furthermore, the bottom surface of the channel is deeper on the side closer to the hinge and shallower on the side closer to the movable side, forming a channel bottom surface with a smooth slope. The filter plate matches the channel bottom surface with a slope, tilting upward from one end closer to the guide mechanism to the other end, parallel to the channel bottom surface.

[0016] Furthermore, two pairs of baffles are detachably installed on the upper and lower sides of the guide block. When the guide block is slidably set on the guide rail, each pair of baffles is symmetrically located on both sides of the guide rail. The baffles cover the gap between the pulley and the slide groove, and anti-jamming protrusions are provided on the baffles. The anti-jamming protrusions extend into the slide groove, and one side is set as an inclined surface.

[0017] The beneficial effects of this utility model are as follows: This municipal garden drainage ditch has a linkage mechanism between the cover and the filter plate. When the cover is lifted, the connecting rod drives the filter plate to rise to the ditch mouth along the guide mechanism, which makes it easy to directly clean up the deposited debris and avoids the operation of manually exploring the ditch. At the same time, the sloping bottom of the ditch and the filter plate structure with filter holes can effectively collect and intercept debris, which improves drainage efficiency and solves the problem of inconvenient cleaning.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] like Figure 1 As shown, a municipal garden drainage ditch includes a straight channel 1, a cover 2 is provided on the top of the channel 1, one side of the cover 2 is a hinged side 5, which is hinged to one side edge of the channel 1 opening, and the other side of the cover 2 is a movable side 6, which is movably connected to the opposite side of the channel 1 opening.

[0026] like Figure 1 As shown, a filter plate 3 is provided at the bottom of the channel 1 located below the cover 2. A guide mechanism is provided between the filter plate 3 and the side wall of the channel 1. The guide mechanism restricts the filter plate 3 to move only along the side wall of the channel 1 and in a direction perpendicular to the axis of the channel 1.

[0027] like Figure 1 , Figure 2As shown, a linkage mechanism connects the filter plate 3 and the cover 2. The linkage mechanism includes several parallel connecting rods 4. One end of each connecting rod 4 is rotatably connected to the side of the filter plate 3 near the guide mechanism, and the other end is rotatably connected to the bottom surface of the cover 2 near the movable side 6. The connecting rod 4 is perpendicular to the axis of the channel 1. When the cover 2 is lifted from the overlapping state, the connecting rod 4 drives the filter plate 3 to rise, moving the filter plate 3 and the debris intercepted on it to the vicinity of the channel opening for easy cleaning. When the cover 2 is lowered from the lifted state, the connecting rod 4 drives the filter plate 3 to descend until it reaches the bottom surface 16 of the channel, restoring the filtration and drainage function.

[0028] like Figure 1 As shown, preferably, the cover 2 is a rectangular plate, and the cover 2 has several drainage holes 7 to allow surface water to flow smoothly into the channel.

[0029] like Figure 1 , Figure 2 As shown, preferably, the guiding mechanism includes a guide rail 8 disposed on the side wall of the channel 1, and the axis of the guide rail 8 is perpendicular to the axis of the channel 1. It also includes a guide block 9 slidably disposed on the guide rail 8. The guide block 9 can move along the axis of the guide rail 8, and the side of the guide block 9 away from the guide rail 8 is fixedly connected to the outer periphery of the filter plate 3, providing precise guidance and support for the lifting and lowering movement of the filter plate 3.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, preferably, the guide rail 8 is a rectangular column fixed to the side wall of the channel 1. The rectangular column has grooves 11 on both sides along its own axis. The guide block 9 is equipped with two pairs of pulleys 10 along its own direction of movement. The rolling direction of the pulleys 10 is parallel to the axis of the grooves 11. When the guide block 9 is slidably positioned on the guide rail 8, each pair of pulleys 10 is symmetrically located in the grooves 11 on both sides of the guide rail 8, and the pulleys 10 abut against the bottom of the grooves 11. This converts sliding friction into rolling friction, effectively reducing movement resistance and making the lifting and lowering of the filter plate 3 more effortless and smooth. Figure 4 , Figure 5 As shown, preferably, the axial cross-section of the chute 11 is semi-circular to reduce the risk of stones and other debris getting stuck.

[0031] like Figure 4 , Figure 5As shown, preferably, two pairs of baffles 17 are detachably installed on the upper and lower sides of the guide block 9. Each pair of baffles 17 is symmetrically arranged on both sides of the guide rail 8. The baffles 17 cover the gap between the pulley 10 and the slide groove 11, and the baffles 17 are provided with anti-jamming protrusions 18. The anti-jamming protrusions 18 extend into the slide groove 11, and one side is set as an inclined surface. If a stone is stuck in the slide groove 11, the anti-jamming protrusions 18 can push the stone out of the slide groove 11 and guide the stone to the outside of the guide rail 8 through the inclined surface.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, preferably, the bottom surface of the cover 2 near the movable side 6 is provided with multiple pairs of hinge ears 12, and the filter plate 3 near the guide rail 8 is also provided with multiple pairs of hinge ears 12. A hinge shaft 13 is provided in each hinge ear 12. The axis of the hinge shaft 13 is parallel to the axis of the channel 1, and hinge holes are opened at both ends of the connecting rod 4. The connecting rod 4 is hinged to the hinge shaft 13 through the hinge holes at both ends. This structure provides a stable and reliable rotation connection point, ensuring the synchronization and stability of the linkage mechanism.

[0033] like Figure 1 As shown, preferably, the filter plate 3 is curved upwards on both sides along the axis of the channel 1, and several isolation plates 14 perpendicular to the axis of the channel 1 are vertically arranged on the filter plate 3. Several filter holes 15 are opened on the isolation plates 14 and the filter plate 3. This structure can intercept larger debris and separate them into different areas to prevent them from accumulating into clumps. This not only ensures the filtration effect, but also makes cleaning more convenient and thorough.

[0034] like Figure 1 , Figure 2 As shown, preferably, the channel bottom surface 16 is deeper on the side closer to the hinge side 5 and shallower on the side closer to the movable side 6, forming a channel bottom surface 16 with a smooth slope. The filter plate 3 matches the channel bottom surface 16 with a slope, and is inclined upward from one end near the guide mechanism to the other end, parallel to the channel bottom surface 16. This facilitates the natural deposition of heavy objects such as sand and gravel carried by the water flow to the deep side of the filter plate 3 under the action of gravity, making it easy to clean.

[0035] Summary of the usage method of this utility model embodiment:

[0036] In normal use, the cover 2 is closed and overlapped at the channel opening. When cleaning is required, the operator lifts the movable side 6 of the cover 2, and the cover 2 rotates around the hinged side 5 to open. Simultaneously, the filter plate 3 is driven up to the channel opening along the guide rail 8 via the connecting rod 4. At this time, the debris deposited on the filter plate 3 can be cleaned in a concentrated manner. After cleaning, the cover 2 is lowered, and the filter plate 3 is lowered back to the bottom surface 16 of the channel, thus restoring normal drainage function.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model 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 this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
