A motor one is arranged at the upper end of the vertical rod, the upper end of the screw rod one is arranged on the output shaft of the motor one after penetrating through the upper end surface of the vertical rod, the screw rod one is driven to rotate by the motor one, thereby driving the horizontal rod to move up and down, so that the filter plate can be taken out of the box body, a handle is arranged on the vertical rod, the vertical rod is rotated by the handle, thereby rotating the filter plate to one side for garbage cleaning.

[0007] An installation groove is arranged on the end surface of one of the horizontal shafts, a chain wheel is arranged around each of the rotating shafts arranged in the installation groove, a plurality of chain wheels are connected by a chain, and corresponding limiting blocks are arranged on both sides of the chain, the limiting blocks being fixed in the installation groove and used for keeping the meshing of the chain and the chain wheels and preventing the chain from falling off. The outer periphery of the end portion of the rotating shaft below the horizontal rod is provided with a gear, and a lower vertical rod is provided on the lower side surface of the horizontal rod, and a slide groove 2 is provided on the corresponding side surface of the lower vertical rod, and a screw rod 2 is provided in the slide groove 2 for rotation between the upper and lower end surfaces, and a screw rod slider 2 is provided on the outer periphery of the screw rod 2 to cooperate with the slide groove 2, and a rack meshing with the gear is provided on the screw rod slider 2, and the upper and lower ends of the rack are provided with limit plates for use with the gear, when the gear contacts the limit plate at the upper end, the filter plate is in a vertical state, and when the gear contacts the limit plate at the lower end, the filter plate is in a horizontal state; A second motor is provided on the upper side surface of the horizontal rod, and the upper end of the second screw rod is provided on the output shaft of the second motor after passing through the horizontal rod. The second motor drives the second screw rod to rotate, thereby driving the rack to slide, thereby driving the gear to rotate, and then driving all the rotating shafts to rotate through the sprocket chain structure, thereby realizing the simultaneous rotation of the filter plate to a vertical state or a flat state.

[0008] The garbage collection mechanism is provided with a sediment collection mechanism, which is provided below the filter plates. Due to the on-site construction environment of the highway, rainwater washes into the water collection pool through the drainage trough, which is bound to contain sediment of various particle sizes. Large particles can be intercepted by the filter plates, but fine sediment will sink to the bottom of the water collection pool, so it needs to be cleaned in time. The sediment collection mechanism includes several groups of downwardly extending fixed rods arranged on several of the horizontal axes, the free ends of the fixed rods are provided with collection trays, and the bottom surface of the box body is provided with several sand falling grooves cooperating with the collection trays, and the collection trays are arranged in the corresponding sand falling grooves.

[0009] There are nine groups of sand falling troughs and they are evenly distributed on the bottom surface of the box in a nine-square grid. The sand falling trough on the outermost diagonal line is the deepest sand falling trough, the three sand falling troughs adjacent to the deepest sand falling trough are the second-deepest sand falling troughs, and the five sand falling troughs adjacent to the three second-deepest sand falling troughs are the second-deepest sand falling troughs. The depth of the deepest sand falling trough is greater than the depth of the second-deepest sand falling trough, and the depth of the second-deepest sand falling trough is greater than the depth of the second-deepest sand falling trough.

[0010] The three secondary deep sand chutes are each provided with an oblique slot hole 1 on the inner bottom surface thereof, connected to the deepest sand chute; the secondary deep sand chutes and the two adjacent secondary deep sand chutes on the same diagonal as the deepest sand chute are each provided with an oblique slot hole 2 on the inner bottom surface thereof, connected to the secondary deep sand chute at the center of the nine-square grid; the remaining two secondary deep sand chutes are respectively connected to the two corresponding secondary deep sand chutes adjacent to the secondary deep sand chutes at the center of the nine-square grid via oblique slot holes 3 on the inner bottom surfaces thereof; There are also nine groups of collecting trays cooperating with the sand falling troughs and they are evenly distributed in a nine-square grid. The heights of the nine groups of collecting trays correspond to the depths of the nine corresponding sand falling troughs, that is, after the sediment collection mechanism extends down to the box body, the lower side surfaces of the collecting trays all rest against the inner bottom surface of the corresponding sand falling trough, which facilitates the collection of sediment.

[0011] Since the collection pool is often large in size, it would be very unsatisfactory to use a whole piece of sediment collection plate for collection, and simply digging by hand is time-consuming and labor-intensive. For this reason, several collection plates are designed, and the sand drop trough is used to improve the collection effect.

[0012] In addition, the depths of the sand-falling troughs are different and are arranged according to a certain pattern. At the same time, the inclined trough hole one, the inclined trough hole two and the inclined trough hole three are designed so that water and part of the sediment are concentrated in the deepest sand-falling trough as much as possible. Especially when the amount of water is small, the water is concentrated in the deepest sand-falling trough for easier use, and the sediment is concentrated in the deepest sand-falling trough as much as possible and is also easy to clean.

[0013] The lowermost edges of the first, second and third chute holes are all higher than the uppermost edges of the corresponding collecting plates, ensuring that water and sediment flowing in from adjacent sand dropout troughs can smoothly enter the corresponding collecting plates, which is conducive to the smooth collection of sediment.

[0014] The bottom surface of the box body is provided with a convex inclined surface structure matched with the sand falling trough, so that the mud and sand in the water fall into the sand falling trough as much as possible, which is convenient for collection.

[0015] A water pump for transporting rainwater to the purification pool is provided in the deepest sand settling trough.

[0016] The application principle is as follows: rainwater passes through the drainage trough and is filtered by the filter mesh before entering the box. Initially, the filter plate is in a horizontal position inside the box. When garbage and sediment need to be cleaned, the first motor is started to drive the filter plate and the collection tray upward and out of the box. The vertical rod is then rotated by the handle to rotate the filter plate and the collection tray to the outside of the box for garbage and sediment cleaning. When the filter plate and the collection tray are then put back into the box, the second motor is first used to make the filter plate vertical, and then it is placed into the box. Finally, the second motor is used to level the filter plate. The water pump transports the water through the first pipeline to the purification tank higher than the water collection tank, and then it is sprayed by the spray device. The purified rainwater can be automatically sprayed mostly by gravity, thus saving energy and reducing usage costs.

[0017] The beneficial effects of the present invention are as follows: the present solution realizes the collection of rainwater, especially the collection of sediment, through the provision of a water collection pool, a purification pool and a spraying device; the cooperation of the collection tray and the sediment drop trough improves the collection effect.

[0018] In addition, the depths of the sediment falling grooves are different and arranged regularly, so that water and part of the sediment are concentrated into the deepest sediment falling groove as much as possible, and the utilization rate of water and the cleaning effect of the sediment are improved.

[0028] In order to clearly illustrate the technical features of the scheme, the scheme will be described below through specific embodiments.

[0029] Referring to Figures 1-5 A highway reconstruction and expansion construction period rainwater collection system, comprising a water collecting pool, a drainage channel used in cooperation with the water collecting pool, a purification pool communicated with the water collecting pool through a first pipeline, and a spraying device communicated with the purification pool through a second pipeline; The water collecting pool is installed in a groove on the ground, and the water collecting pool comprises a box body 1 with an open upper end, and a filter screen 2 arranged around the outer periphery of the upper end of the box body 1; The drainage channel is provided with a plurality of drainage channels, and the plurality of drainage channels are arranged around the water collecting pool and cooperate with the filter screen 2. The water in the drainage channel flows into the water collecting pool through the filter screen 2, and the impurities in the drainage channel are intercepted outside by the filter screen 2, and then can be cleaned by manual or other means.

The garbage collecting mechanism is used for collecting garbage floating on the water surface or sundries falling into the water. Since garbage cannot be avoided from falling into the water during the use of the water collecting pool, it is necessary to design the garbage collecting mechanism. Initially, all the filter plates 8 are in a spread state and submerged into the water in the box body 1 and just cover the whole cross section of the box body 1, so as to collect the garbage on the water surface upward. After the garbage is cleaned, the filter plates 8 are rotated to a vertical state, because the vertical state is easier to enter the water in the box body 1 and will not press the newly fallen garbage into the water.

[0031] The support frame comprises a vertical rod 3 rotatably arranged on the base, a sliding groove one arranged on the side surface of the vertical rod 3, a screw rod one 4 rotatably arranged between the upper and lower side end surfaces of the sliding groove one, a screw rod sliding block one arranged around the screw rod one 4 and matched with the sliding groove one, a horizontal rod 6 arranged on the screw rod sliding block one, the horizontal rod 6 being parallel to the rotating shaft 9, a lower extension rod 7 arranged on the lower side surface of the horizontal rod 6 close to the free end, and the lower end of the lower extension rod 7 being fixed on the main shaft 14. A motor one 5 is arranged at the upper end of the vertical rod 3, the upper end of the screw rod one 4 is arranged on the output shaft of the motor one 5 after penetrating through the upper end surface of the vertical rod 3, the screw rod one 4 is driven to rotate by the motor one 5, so as to drive the horizontal rod 6 to move up and down, thereby the filter plate 8 can be taken out of the box body 1.

[0032] An installation groove is arranged on the end surface of one horizontal shaft 10, a chain wheel is arranged around each of the plurality of rotating shafts 9 in the installation groove, the plurality of chain wheels are connected by a chain, and corresponding limiting blocks are arranged on both sides of the chain, the limiting blocks being fixed in the installation groove and used for keeping the meshing of the chain and the chain wheel and preventing the chain from falling off. A gear 19 is arranged around the end part of the rotating shaft 9 below the horizontal rod 6, a lower vertical rod 11 is arranged on the lower side surface of the horizontal rod 6, a sliding groove two is arranged on the corresponding side surface of the lower vertical rod 11, a screw rod two is rotatably arranged between the upper and lower side end surfaces of the sliding groove two, a screw rod sliding block two is arranged around the screw rod two and matched with the sliding groove two, a rack 18 is arranged on the screw rod sliding block two and meshed with the gear 19, and limiting plates 20 matched with the gear 19 are arranged at the upper and lower ends of the rack 18. When the gear 19 is in contact with the limiting plate 20 at the upper end, the filter plate 8 is in a vertical state. When the gear 19 is in contact with the limiting plate 20 at the lower end, the filter plate 8 is in a horizontal state. A second motor 12 is provided on the upper side surface of the horizontal rod 6. The upper end of the second screw rod passes through the horizontal rod 6 and is provided on the output shaft of the second motor 12. The second motor 12 drives the second screw rod to rotate, thereby driving the rack 18 to slide, thereby driving the gear 19 to rotate, and then drives all the rotating shafts 9 to rotate through the sprocket chain structure, thereby realizing the simultaneous rotation of the filter plate to a vertical state or a flat state.

[0033] The garbage collection mechanism is provided with a sediment collection mechanism, which is provided below a number of filter plates 8. Due to the on-site construction environment of the highway, rainwater washes through the drainage trough into the water collection pool, which is inevitably mixed with sediment of various particle sizes. Large particles can be intercepted by the filter plates 8, but fine sediment will sink to the bottom of the water collection pool, so it needs to be cleaned in time. The sediment collection mechanism includes several groups of downwardly extending fixed rods 16 arranged on several horizontal axes 10, and the free ends of the fixed rods 16 are provided with collection trays 17. The bottom surface of the box body 1 is provided with several sand falling troughs cooperating with the collection trays 17, and the collection trays 17 are arranged in the corresponding sand falling troughs.

[0034] There are nine groups of sand falling troughs and they are evenly distributed on the bottom surface of the box body 1 in the form of a nine-square grid. The sand falling trough on the outermost diagonal line is the deepest sand falling trough 21, the three sand falling troughs adjacent to the deepest sand falling trough 21 are the second-deepest sand falling troughs 22, and the five sand falling troughs adjacent to the three second-deepest sand falling troughs 22 are the second-deepest sand falling troughs 23. The depth of the deepest sand falling trough 21 is greater than the depth of the second-deepest sand falling trough 22, and the depth of the second-deepest sand falling trough 22 is greater than the depth of the second-deepest sand falling trough 23.

[0035] The inner bottom surfaces of the three secondary deep sand chutes 22 are each provided with an oblique slot hole 1 24 connected to the deepest sand chute 21. The inner bottom surfaces of the secondary deep sand chutes 23 and the two adjacent secondary deep sand chutes 23 on the same diagonal as the deepest sand chutes 21 are each provided with an oblique slot hole 25 connected to the secondary deep sand chutes 22 at the center of the nine-square grid. The inner bottom surfaces of the remaining two secondary deep sand chutes 23 are respectively connected to the two corresponding secondary deep sand chutes 22 adjacent to the secondary deep sand chutes 22 at the center of the nine-square grid via oblique slot holes 3 26. There are also nine groups of collecting trays 17 that cooperate with the sand falling troughs and are evenly distributed in the form of a nine-square grid. The heights of the nine groups of collecting trays 17 correspond to the depths of the nine corresponding sand falling troughs. That is, after the sediment collection mechanism extends down to the box body 1, the lower side surfaces of the collecting trays 17 all rest against the bottom surface of the corresponding sand falling trough, which facilitates the collection of sediment.

[0036] Since the water collection pool is often large in size, it would be very unsatisfactory to use a whole piece of sediment collection tray 17 for collection, and simply digging by hand is time-consuming and labor-intensive. Therefore, a number of collection trays 17 are designed, and the sand drop trough is used to improve the collection effect.

[0037] In addition, the depths of the sand falling grooves are different and arranged in a certain rule, and the chute hole one 24, the chute hole two 25 and the chute hole three 26 are designed, so that water and part of the sand are concentrated into the deepest sand falling groove 21 as much as possible, especially when the water quantity is small, the water is concentrated into the deepest sand falling groove 21 and is more easily taken, and the sand concentrated into the deepest sand falling groove 21 is also easily cleaned.

[0038] The lowermost edges of the chute hole one 24, the chute hole two 25 and the chute hole three 26 are higher than the uppermost edges of the corresponding collecting discs 17, so that the water and the sand flowing from the adjacent sand falling grooves can smoothly enter the corresponding collecting discs 17, and the sand is smoothly collected.

[0039] The convex slope structure 27 matched with the sand falling grooves is arranged on the inner bottom surface of the box body 1, so that the sand in the water is as much as possible to fall into the sand falling grooves, and the collection is facilitated.

[0040] The water pump for conveying the rainwater to the purification tank is arranged in the deepest sand falling groove 21.

[0041] The application principle is as follows: the rainwater enters into the box body 1 through the drainage groove and the filter screen 2, at the beginning, the filter plate 8 is in a horizontal state in the box body 1, when the garbage and the sand need to be cleaned, the motor one 5 drives the filter plate 8 and the collecting disc 17 to move upwards and leave the box body 1, then the handle is rotated to rotate the vertical rod 3, so that the filter plate 8 and the collecting disc 17 are rotated to one side outside the box body 1 to clean the garbage and the sand, then when the filter plate 8 and the collecting disc 17 are put back into the box body 1, the motor two 12 is used to make the filter plate 8 in a vertical state, then the filter plate 8 is put into the box body 1, and finally the filter plate 8 is put flat by the motor two 12. The water pump conveys the water to the purification tank which is higher than the water collecting tank through the first pipeline, then the water is sprayed by the spraying device, and the purified rainwater can be automatically sprayed by the gravity, so that the energy is saved and the use cost is reduced.

[0042] The technical features not described in the application can be realized by or using the prior art, which will not be repeated here, of course, the above description is not a limitation of the application, the application is not limited to the above examples, the changes, modifications, additions or replacements made by the ordinary skilled in the art within the essential scope of the application should also belong to the protection scope of the application.
