Description

Technical Field

[0001] The present invention relates to the technical field of road and bridge drainage, and particularly relates to a road and bridge drainage device. Background Art

[0002] Once water accumulates on the bridge deck on a rainy day, the tires of vehicles driving at high speed on it will be affected by the accumulated water and slip or get out of control, resulting in serious traffic accidents such as vehicle skidding or rollover.

[0003] When building a road bridge, a corresponding drainage structure needs to be built to drain the accumulated water on the bridge or viaduct through drainage pipes, so as to ensure the driving safety on the bridge deck. At the same time, in order to prevent debris such as stones from blocking the drainage pipes on the bridge or viaduct, a filter screen is generally installed at the inlet of the drainage pipe to prevent stones or other debris from entering the inlet of the drainage pipe.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0077] The present invention provides a road and bridge drainage device as Figure 1-7 shown, including:

[0078] A drainage pipeline 100;

[0079] A diversion pipeline 200, which is fixed at the bottom of the drainage pipeline 100 and communicates with the drainage pipeline 100;

[0080] A filtering component 300, which is rotatably installed inside the diversion pipeline 200 and filters rainwater;

[0081] A lifting partition plate 400, which is slidably installed up and down inside the drainage pipeline 100;

[0082] A sealing component 500, which is slidably installed up and down inside the lifting partition plate 400, releases the seal of the lifting partition plate 400 when the lifting partition plate 400 descends, and seals the lifting partition plate 400 when the lifting partition plate 400 ascends;

[0083] A limiting device 600, which is installed inside the drainage pipeline 100 and limits the height of the lifting partition plate 400 after the lifting partition plate 400 descends;

[0084] A driving device 700, which is fixed at the bottom of the lifting partition plate 400 and drives the filtering component 300 to rotate when the lifting partition plate 400 ascends and descends;

[0085] A plurality of rubber columns 800 are provided and are evenly distributed in a circular array. The top and bottom of the rubber columns 800 are bonded to the lifting partition plate 400 and the drainage pipeline 100 respectively;

[0086] A sewage storage component 900, which communicates with the diversion pipeline 200.

[0087] Among them, by driving the lifting and lowering of the lifting and dividing plate 400, the filtering component 300 is rotated, so that the filtering component 300 rotates from the filtering state to the self-cleaning state, realizing the cleaning of the filtering component 300, and transporting the accumulated debris after cleaning to the inside of the sewage storage component 900 for centralized treatment. At the same time, after the filtering component 300 is cleaned, it will quickly reset for filtering use, improving the drainage effect. At the same time, there is no need to clean the drainage outlet during drainage, avoiding the long-term existence of accumulated water on the bridge or viaduct;

[0088] Among them, the setting of the rubber column 800 can adjust the height according to the water storage volume on the lifting and dividing plate 400, so that the lifting and dividing plate 400 descends when the filtering component 300 is blocked and rises when the blockage is released, realizing the automatic cleaning of the filtering component 300 during use;

[0089] Among them, the setting of the driving device 700 realizes the lifting of the lifting and dividing plate 400 to drive the filtering component 300 to rotate and adjust the filtering state of the filtering component 300.

[0090] In some embodiments of the present invention, the drainage pipeline 100 includes:

[0091] An outer pipeline 110;

[0092] An inner pipeline 120, which is fixed inside the outer pipeline 110 and is communicated with the diversion pipeline 200;

[0093] A water storage space 130, which is arranged between the outer pipeline 110 and the inner pipeline 120;

[0094] A plurality of first water inlet through holes 140 are provided, and are arranged in an annular array on the upper part of the inner pipeline 120;

[0095] A top cover 150, which is detachably fixed at the top opening of the outer pipeline 110.

[0096] Among them, the setting of the inner pipeline 120 can ensure the normal discharge and flow of the accumulated water on the bridge or viaduct, preventing the long-term existence of accumulated water on the bridge or viaduct from affecting the normal passage of vehicles;

[0097] Among them, the setting of the water storage space 130 can store the accumulated water when the filtering component 300 is blocked, increasing the weight of the accumulated water on the lifting and dividing plate 400, and driving the lifting and dividing plate 400 to descend as the weight increases;

[0098] Among them, the setting of the first water inlet through hole 140 diverts the accumulated water into the inside of the water storage space 130 for storage after the water level inside the inner pipeline 120 rises to a certain height, and under the action of the weight of the accumulated water, the lifting and dividing plate 400 is pushed to descend and the rubber column 800 is compressed;

[0099] Among them, the top opening of the water storage space 130 is blocked by the setting of the top cover 150. At the same time, a blocking device can be set on the top cover 150 to prevent the accumulated water from entering the interior of the inner pipe 120 when the filter component 300 is self-cleaned, and open the top cover 150 after the filter component 300 is self-cleaned to allow the accumulated water to enter normally.

[0100] In some embodiments of the present invention, the flow guide pipeline 200 includes:

[0101] A receiving pipe 210, which is fixed to the bottom of the outer pipe 110 and communicates with the inner pipe 120;

[0102] A spherical pipe 220, the spherical pipe 220 is fixed to the bottom of the receiving pipe 210;

[0103] Socket joints 230, two socket joints 230 are provided and symmetrically fixed on the outside of the spherical pipe 220;

[0104] The water conduit 240 has two ends which are respectively connected to the water storage space 130 and the spherical conduit 220 .

[0105] The setting of the receiving pipe 210 ensures the normal communication between the spherical pipe 220 and the inner pipe 120, and ensures the normal use of the spherical pipe 220;

[0106] The socket 230 is provided to ensure the sealing of the extended position of the filter assembly 300, thereby preventing the accumulated water from seeping out from the socket 230;

[0107] The water conduit 240 is arranged to guide the accumulated water in the water storage space 130 into the spherical conduit 220 when the lifting partition plate 400 is opened, and flush the rotating filter assembly 300, and flush the filtered deposits into the sewage storage assembly 900 for storage;

[0108] Among them, the water inflow of the first water inlet hole 140 is less than the water discharge of the filter component 300 after self-cleaning. After the filter component 300 self-cleans, the amount of water accumulated inside the water storage space 130 will decrease, causing the lifting partition plate 400 to rise under the elastic force of the rubber column 800.

[0109] In some embodiments of the present invention, the filter assembly 300 includes:

[0110] A spherical component 310, the spherical component 310 is rotatably mounted inside the spherical pipe 220;

[0111] Extension columns 320, two of which are provided and fixed to the outside of the spherical component 310 and pass through the socket 230;

[0112] Gear 330 is fixed to one end of the extension column 320 away from the spherical assembly 310;

[0113] A coil spring 340, and both ends of the coil spring 340 are detachably and fixedly connected to the extension column 320 and the inner wall of the receiving joint 230 respectively.

[0114] Among them, through the setting of the extension column 320, it extends to the outside of the spherical pipe 220, and ensures the normal installation of the gear 330 and the coil spring 340;

[0115] Among them, through the setting of the gear 330, it is connected to the driving device 700, and when the lifting partition plate 400 descends, the spherical assembly 310 is driven to rotate by the driving device 700 and the gear 330, adjusting the state of the spherical assembly 310, so that the spherical assembly 310 is adjusted back and forth between the filtering and self-cleaning states;

[0116] Among them, through the setting of the coil spring 340, after the water level above the lifting partition plate 400 drops, it can drive the lifting partition plate 400 to rise and reset, and at the same time drive the spherical assembly 310 to rotate, so that the spherical assembly 310 changes back from the self-cleaning state to the filtering state, and the spherical assembly 310 is used for normal filtering.

[0117] In some embodiments of the present invention, the spherical assembly 310 includes:

[0118] A spherical head 311, which is rotatably installed inside the spherical pipe 220 and fixedly connected to the extension column 320;

[0119] Sealing strips 312, multiple sealing strips 312 are provided and fixed on the outside of the spherical head 311 in contact with the inner wall of the spherical pipe 220;

[0120] A diversion channel 313 is vertically and throughly opened in the middle of the spherical head 311;

[0121] Three filter meshes 314 are provided, and are equidistantly fixed inside the diversion channel 313, and the diameters of the filter holes of the three filter meshes 314 decrease in sequence from top to bottom.

[0122] Among them, through the cooperation of the spherical head 311 and the sealing strips 312, it contacts with the spherical pipe 220 and is sealed, so that the diversion channel 313 is always kept sealed before being communicated with the receiving joint 230 and the water guiding pipe 240;

[0123] Among them, through the setting of the diversion channel 313, it ensures the normal flow of accumulated water, so that the accumulated water can flow out;

[0124] Among them, the filter screen 314 can filter the deposits in the accumulated water, and the diameters of the filter holes of the three filter screens 314 decrease in sequence, which can separate and filter deposits of different sizes, reducing the probability of the filter screen 314 being blocked during use.

[0125] In some embodiments of the present invention, the lifting and dividing plate 400 includes:

[0126] A sealing plate 410, which is slidably installed inside the water storage space 130 and bonded to the rubber column 800;

[0127] A plurality of second water inlet through holes 420, which are formed in an annular array and uniformly arranged on the sealing plate 410;

[0128] A guide cylinder 430, which is fixed on the top of the sealing plate 410 and corresponds to the second water inlet through hole 420;

[0129] A plurality of third water inlet through holes 440, which are formed in an annular array and uniformly arranged on the outer side of the guide cylinder 430.

[0130] Among them, through the setting of the sealing plate 410 in contact and sealed with the outer pipe 110 and the inner pipe 120, it can be avoided that when the sealing plate 410 does not descend to the corresponding height, the accumulated water will not flow out, affecting the self-cleaning of the filter screen 314;

[0131] Among them, through the setting of the second water inlet through hole 420, after it is opened, the accumulated water above the sealing plate 410 is diverted to the lower part, so that the accumulated water can enter the inside of the diversion channel 313 through the water guide pipe 240 to clean the filter screen 314;

[0132] Among them, through the setting of the guide cylinder 430, the sliding of the sealing component 500 is guided to avoid the sealing component 500 shifting during up and down sliding, affecting the normal sealing of the second water inlet through hole 420; through the setting of the third water inlet through hole 440, after the second water inlet through hole 420 is opened, the accumulated water is diverted into the inside of the guide cylinder 430 and flows downward through the second water inlet through hole 420.

[0133] In some embodiments of the present invention, the sealing component 500 includes:

[0134] A sealing disc 510, which is slidably installed inside the guide cylinder 430 and plugs the second water inlet through hole 420 when descending;

[0135] The draw ropes 520 are provided with two, which are respectively fixed to the top and bottom of the sealing disc 510. The upper draw rope 520 is fixedly connected to the top cover 150, and the lower draw rope 520 is fixedly connected to the inner bottom wall of the outer pipe 110.

[0136] Among them, through the setting of the draw ropes 520, the height of the sealing disc 510 can be pulled up and down according to the height of the lifting partition plate 400, so that the sealing disc 510 can lift to release the blockage of the second water inlet through hole 420 or block the second water inlet through hole 420, enabling the water inside the water storage space 130 to flow normally.

[0137] Among them, through the setting of the sealing disc 510, the second water inlet through hole 420 can be blocked, and the length of the draw rope 520 is preset. When the lifting partition plate 400 descends to the lowest position, the upper draw rope 520 pulls the sealing disc 510 to rise. When the lifting partition plate 400 rises to the highest position, the lower draw rope 520 pulls the sealing disc 510 to descend, so that the initial lifting and lowering of the lifting partition plate 400 will not affect the position of the sealing disc 510.

[0138] In some embodiments of the present invention, the limiting device 600 includes:

[0139] Installation grooves 610 are provided with a plurality of them, which are arranged in an annular array on the inner wall of the outer pipe 110.

[0140] Compression springs 620 are fixed inside the installation grooves 610.

[0141] Limit heads 630 are slidably installed inside the installation grooves 610 and are detachably fixedly connected to the compression springs 620.

[0142] Among them, the setting of the installation grooves 610 provides space for the installation of the compression springs 620 and the limit heads 630, and at the same time ensures the normal sliding of the limit heads 630.

[0143] Among them, through the cooperative setting of the compression springs 620 and the limit heads 630, the height of the sealing plate 410 is restricted, preventing the sealing plate 410 from rising immediately when the water level on it drops, and ensuring the stability of water conduction.

[0144] Among them, the sum of the limiting force of the limit head 630 on the sealing plate 410, the elastic force of the rubber column 800, and the stress of the coil spring 340 is less than the acting force of the full accumulated water weight inside the water storage space 130 on the sealing plate 410, enabling the sealing plate 410 to descend normally. The sum of the elastic force of the rubber column 800 and the stress of the coil spring 340 is greater than the limiting force of the limit head 630 on the sealing plate 410. After a certain amount of accumulated water is discharged, the sealing plate 410 can rise normally.

[0145] In some embodiments of the present invention, the driving device 700 includes:

[0146] A lower pressing plate 710, which is fixed to the bottom of the sealing plate 410 and passes downward through the outer pipe 110;

[0147] A gear plate 720, which is fixed to the bottom of the lower pressing plate 710 and meshes with the gear 330.

[0148] Wherein, the setting of the lower pressing plate 710 ensures the installation and fixation of the gear plate 720. At the same time, the lower pressing plate 710 is hermetically arranged with the outer pipe 110 to prevent water from seeping out, and drives the gear plate 720 to rise and fall with the sealing plate 410;

[0149] Wherein, the descent of the gear plate 720 drives the gear 330 to rotate, causing the gear 330 to drive the spherical head 311 to rotate. And when the force of the coil spring 340 is released, it will cause the gear 330 to drive the gear plate 720 to rise and drive the sealing plate 410 to rise.

[0150] In some embodiments of the present invention, the sewage storage assembly 900 includes:

[0151] An inclined pipe 910, which is fixed to the outside of the spherical pipe 220 and is arranged obliquely downward;

[0152] A sewage storage well 920, which is arranged on one side of the drainage pipeline 100 and is communicated with the spherical pipe 220 through the inclined pipe 910.

[0153] Wherein, the setting of the inclined pipe 910 transports the filtered deposits to the inside of the sewage storage well 920, and the inclined setting of the inclined pipe 910 can better enter the inside of the sewage storage well 920 under the scouring of accumulated water;

[0154] Wherein, the setting of the sewage storage well 920 can store the scoured deposits, which is convenient for the later cleaning of the deposits and will not affect the normal use of the device during cleaning.

[0155] The working method of the present invention:

[0156] During use, the accumulated water enters the inside of the inner pipe 120 through the top cover 150 and is discharged through the diversion channel 313. When passing through the diversion channel 313, it is filtered by three filter meshes 314 to filter the debris in the accumulated water;

[0157] When the filter screen 314 is clogged, the water level of the accumulated water in the inner pipe 120 will rise and reach the first water inlet hole 140, and then enter the water storage space 130 through the first water inlet hole 140. As the water accumulated in the water storage space 130 increases, the sealing plate 410 will descend and squeeze the rubber column 800, so that the rubber column 800 is compressed and accumulates force. At the same time, when the sealing plate 410 descends, it will also drive the lower pressure plate 710 and the gear plate 720 to descend, and when the gear plate 720 descends, the gear 330 is driven to rotate, so that the gear 330 drives the spherical head 311 to rotate by driving the extension column 320, and at the same time When the sealing plate 410 is lowered, the coil spring 340 is driven to store force, so that the openings at both ends of the diversion channel 313 correspond to the water diversion pipe 240 and the inclined pipe 910 respectively, and as the sealing plate 410 descends, the limiting head 630 is squeezed, so that the limiting head 630 moves toward the inside of the installation groove 610 and squeezes the compression spring 620. When the sealing plate 410 and the limiting head 630 are staggered, the limiting head 630 pops out to limit the sealing plate 410. At the same time, when the sealing plate 410 contacts the limiting head 630, as the sealing plate 410 descends, the pull rope 520 located above will pull the sealing plate 510 up to open the second water inlet hole 420.

[0158] When the second water inlet hole 420 is opened, the accumulated water inside the water storage space 130 will flow downward through the second water inlet hole 420 and the third water inlet hole 440, and the drainage volume of the second water inlet hole 420 and the third water inlet hole 440 is less than the water inlet volume of the first water inlet hole 140, and the accumulated water enters the interior of the diversion channel 313 through the water guide pipe 240, and flushes the filter screen 314, and the water inlet opening of the diversion channel 313 corresponds to the water guide pipe 240, and the flushed debris will enter the interior of the sewage storage well 920 through the inclined pipe 910;

[0159] When the accumulated water above the sealing plate 410 drops to a certain water level, the rubber column 800 will push the sealing plate 410 to rise. At the same time, the force of the coil spring 340 is released, so that the coil spring 340 drives the spherical head 311 to rotate and reset, and the diversion channel 313 and the receiving pipe 210 are drained normally. At the same time, the gear plate 720 is driven to rise, so that the gear plate 720 drives the sealing plate 410 to rise, and the sealing plate 410 squeezes the limit head 630, and passes the limit head 630. After the sealing plate 410 rises to the corresponding height, the pull rope 520 below drives the sealing plate 510 to descend and seals the second water inlet hole 420.
