Description

Technical Field

[0001] This application relates to the field of road and bridge construction, and in particular to a road and bridge construction pavement drainage system. Background Technology

[0002] my country's road and bridge industry has developed rapidly. With the continuous improvement of people's living standards, the requirements for the quality of roads and bridges have also increased. In order to quickly remove water accumulated on bridge construction sites and prevent rainwater from accumulating on the bridge surface, affecting the lifespan of the bridge and traffic, it is necessary to drain the road surface during road and bridge construction.

[0003] In related technologies, application document CN214459606U discloses a drainage device for roads and bridges, including a road body, a kiln cover assembly installed on the inner side of the road body, a water collection tank installed below the road body, a filter plate installed on the inner side of the water collection tank, a drain pipe installed on one side of the water collection tank and at a position corresponding to the filter plate, a rotating column set above the filter plate, the rotating column and the water collection tank being connected by a bearing, a drive device installed at one end of the rotating column, and an adjustment device installed below the water collection tank. Rotating the knob in the adjustment device causes the knob to drive the drive wheel inside the fixed housing to rotate via a rotating shaft. The drive wheel drives two driven wheels to rotate via a belt. The driven wheels drive the moving frame to descend via a rotating screw and screw sleeve, thereby driving the base plate and vibration assembly to descend, so that some water cannot be discharged by the drain pipe during drainage and remains in the lower tank for water storage.

[0004] Regarding the aforementioned technologies, water from the road enters the water collection tank through the kiln cover assembly. Then, the lower tank can store the water. Sometimes, rainwater from the road may flow into the water collection tank mixed with leaves or gravel. At this time, the rainwater mixed with leaves or gravel can be separated by the filter plate, and the leaves or gravel fall onto the filter plate. However, as the amount of leaves or gravel increases, it may clog the filter plate, making it difficult to clean the filter plate. Summary of the Invention

[0005] To address the issue of difficulty in cleaning filter plates, this application provides a road and bridge construction pavement drainage system.

[0006] The road and bridge construction pavement drainage system provided in this application adopts the following technical solution:

[0007] A road and bridge construction pavement drainage system includes a manhole in the road body and a drainage channel in the manhole, which is connected to the manhole. The system includes a fixing component, a drainage component, and a filtering component. The fixing component includes a drainage pipe for drainage, which is located in the drainage channel. The drainage component is located at the manhole and is detachably connected to the drainage pipe. The drainage component is used for drainage.

[0008] The filter assembly is located on the side of the drainage assembly near the drain pipe. The filter assembly includes a first conical filter and a second conical filter. The opening of the first conical filter faces the drainage assembly and is connected to the drainage assembly. The second conical filter is located inside the first conical filter and is oriented in the same direction as the first conical filter. The second conical filter is connected to the drainage assembly, and the filter holes of the second conical filter are larger than those of the first conical filter. A buffer gap is provided between the first conical filter and the second conical filter.

[0009] By adopting the above technical solution, when it rains, rainwater falls on the road surface and flows towards the manhole. Then, the rainwater, mixed with leaves and gravel, flows through the drainage components to the drainage ditch. Afterward, the rainwater flows into the second conical filter screen, and then to the first conical filter screen. The second and first conical filters separate the leaves and gravel from the rainwater. The filtered rainwater then flows through the first conical filter screen into the drain pipe. The rainwater flows along the drain pipe to a designated location, where it undergoes double-layer filtration through the second and first conical filters for better rainwater filtration. When it is necessary to... When cleaning the second and first conical filters, separate the drainage assembly from the drain pipe, then open the drainage assembly to clean the second and first conical filters. After cleaning, install the first and second conical filters and the drainage assembly in the designated positions. Compared with related technologies, this application uses a double-layer filtration system with the second and first conical filters to better filter rainwater. By separating the drainage assembly from the drain pipe, the filter assembly can be removed from the drain trough. Opening the drainage assembly allows for cleaning of the first and second conical filters, which helps to improve the problem of difficult filter cleaning.

[0010] Optionally, the drainage assembly includes a fixing ring located at the wellhead, the fixing ring being detachably connected to the drainage pipe, and a connecting ring being detachably connected to the side of the fixing ring near the drainage pipe. Both the first conical filter screen and the second conical filter screen are connected to the fixing ring.

[0011] The road and bridge construction pavement drainage system also includes at least one pressing component. A pressing groove is formed at the manhole of the road body, and a connecting hole is formed between the road body and the pressing groove, connecting the pressing groove and the drainage channel. The pressing component corresponds to the pressing groove and includes a hinge seat, a connecting rod, a pressing element, and a guide rod. The hinge seat is located within the connecting hole and is fixed to the road body. The connecting rod is horizontally hinged to the hinge seat, with one end located within the pressing groove. A guide groove is formed on the side of the drainage pipe near the connecting hole, extending along the length of the drainage pipe. The other end of the connecting rod extends into the guide groove. The pressing element is hinged to the end of the connecting rod located within the pressing groove. The guide rod is vertically positioned, with one end hinged to the connecting rod located at one end of the guide groove, and the other end hinged to the connecting ring.

[0012] By adopting the above technical solution, when it is necessary to clean the first and second conical filters, personnel move to the pressing groove and activate the pressing component. The pressing component drives the connecting rod to rotate around the hinge seat towards the bottom of the pressing groove at one end. At this time, the connecting rod rotates around the hinge seat towards the side closer to the fixed ring at one end. During the rotation of the connecting rod, the connecting rod can push the guide rod towards the side closer to the fixed plate. While the guide rod pushes the connecting ring, the connecting ring pushes the fixed ring to move, causing the fixed ring and the wellhead to separate. Subsequently, personnel separate the fixed ring and the connecting ring. At this time, the first and second conical filters can be removed from the drain pipe, making it convenient for personnel to clean the first and second conical filters. By setting up the pressing component, it is easy for personnel to separate the fixed ring and the wellhead, and easy to remove the first and second conical filters from the drain pipe, which further helps to improve the problem of difficult filter cleaning.

[0013] Optionally, the drainage assembly further includes a cover plate, a driving component, and a sensing component. The cover plate is located inside the fixing ring and fits into the fixing ring. The cover plate includes multiple horizontally arranged fan-shaped fixing plates, multiple horizontally arranged fan-shaped adjusting plates, and a fixing plate. The multiple fan-shaped fixing plates and multiple fan-shaped adjusting plates are distributed alternately. The fixing plate is located at the center of the fixing ring and is rotatably connected to the fixing plate. The fan-shaped fixing plates are fixed to the fixing plate and are used to adjust the size of the drain outlet between two adjacent fan-shaped fixing plates. The driving component is fixed to the side of the fan-shaped fixing plate near the drain pipe and is connected to the fixing plate to drive the fixing plate to rotate. The sensing component is fixed to the side of the fan-shaped fixing plate away from the drain pipe and is used to sense the water volume. The sensing component is electrically connected to the driving component.

[0014] By adopting the above technical solution, when rainwater flows along the road surface to the manhole, the sensor detects the amount of water and transmits the signal to the drive unit. The drive unit then rotates the fan-shaped adjusting plate, adjusting the size of the drainage outlet between two adjacent fan-shaped fixed plates. When the sensor detects a large amount of water, it transmits the signal to the drive unit, which in turn drives the fixed plate to rotate. During the rotation of the fixed plate, the fan-shaped adjusting plate rotates with it, enlarging the drainage outlet between two adjacent fan-shaped fixed plates, facilitating rainwater drainage. The rainwater falls into the second conical filter screen and is then discharged through the drain pipe. When cleaning the second conical filter screen is required, it is removed from the drain pipe, and the drive unit is activated. The drive unit then drives the fan-shaped adjusting plate, enlarging the drainage outlet between two adjacent fan-shaped fixed plates, facilitating cleaning of the second conical filter screen. By coordinating the sensor, drive unit, fan-shaped fixed plate, and fan-shaped adjusting plate, rainwater drainage and cleaning of the second conical filter screen are both facilitated.

[0015] Optionally, the first conical filter screen has a cleaning port on its side wall, and a cleaning plate is installed at the cleaning port on the first conical filter screen. The cleaning plate is used to open or close the cleaning port.

[0016] By adopting the above technical solution, when it is necessary to clean the first conical filter screen, the first and second conical filters screens are removed from the drain pipe. The second conical filter screen is cleaned by the cooperation of the fan-shaped adjusting plate and the fan-shaped fixing plate. Personnel open the cleaning plate and clean the first conical filter screen through the cleaning port. By setting the cleaning port and cleaning plate, it is convenient to clean the first conical filter screen. Closing the cleaning port by the cleaning plate helps to reduce the entry of leaves and gravel on the first conical filter screen into the drain pipe.

[0017] Optionally, a drive assembly is also included, located within the second conical filter. The drive assembly includes a rotating shaft and a transmission component. The rotating shaft is vertically arranged, with one end passing through the lowest point of the second conical filter and the lowest point of the first conical filter in sequence. The rotating shaft is fixed to the second conical filter and the first conical filter in sequence. The end of the rotating shaft away from the second conical filter is rotatably connected to the fan-shaped fixing plate. The transmission component is fixed to the fan-shaped fixing plate and connected to the rotating shaft to drive the rotating shaft to rotate.

[0018] By adopting the above technical solution, when rainwater enters the second conical filter, the transmission component is activated, which drives the rotating shaft to rotate. During the rotation of the rotating shaft, the second and first conical filters rotate with the rotating shaft. During the rotation of the second and first conical filters, the rainwater can be centrifugally filtered. By setting the drive component, it is beneficial to filter rainwater.

[0019] Optionally, the transmission component includes a transmission rod, a first bevel gear, a second bevel gear, and multiple rotating plates. The transmission rod is horizontally positioned at one end of the rotating shaft near the fixed ring. The transmission rod is rotatably connected to the sector-shaped fixed plate. The first bevel gear is coaxially fixed to the outer peripheral wall of the transmission rod, and the second bevel gear is coaxially fixed to the outer peripheral wall of the rotating shaft. The first bevel gear and the second bevel gear mesh. The multiple rotating plates are all fixed to the end of the transmission rod away from the rotating shaft. The multiple rotating plates are distributed circumferentially along the outer peripheral wall of the transmission rod. The multiple rotating plates are located below the drain outlet between two adjacent sector-shaped fixed plates. When rainwater flows into the drain pipe through the drain outlet, the rainwater impacts the rotating plates.

[0020] By adopting the above technical solution, when rainwater flows through the drain outlet between two adjacent fan-shaped fixed plates into the second conical filter screen, the rainwater simultaneously impacts the rotating plate. Under the impact of the rainwater, the rotating plate and the transmission rod can rotate. During the rotation of the transmission rod, the first bevel gear rotates with the transmission rod, and the second bevel gear rotates with the first bevel gear. The second bevel gear drives the rotating shaft to rotate. At this time, the first and second conical filters rotate, filtering the rainwater. By setting the rotation plate, transmission rod, first bevel gear, and second bevel gear in coordination, on the one hand, it is convenient to make the first and second conical filters rotate; on the other hand, the transmission rod is driven to rotate by rainwater, which is beneficial to energy conservation and environmental protection.

[0021] Optionally, the filter assembly further includes multiple buffer components, all distributed within a buffer gap. Each buffer component includes a telescopic rod, an abutment plate, and a first spring. The telescopic rod is positioned from the first conical filter screen toward the second conical filter screen. One end of the telescopic rod is fixed to the first conical filter screen, and the other end is fixed to the abutment plate, which abuts against the second conical filter screen. The first spring is sleeved on the outer peripheral wall of the telescopic rod, with one end fixed to the first conical filter screen and the other end fixed to the abutment plate.

[0022] By adopting the above technical solution, when rainwater mixed with leaves and gravel enters the second conical filter, the leaves and gravel exert force on the second conical filter due to their own gravity. At this time, the second conical filter pushes the abutment plate toward the first conical filter, the telescopic rod shortens, and the first spring is compressed. By setting a buffer, it is beneficial to reduce the damage to the second and first conical filters.

[0023] Optionally, a plurality of insert rods are fixed on the side of the fixing ring near the drain pipe. The plurality of insert rods are distributed circumferentially along the fixing ring. A plurality of slots for inserting the insert rods are opened at the end of the drain pipe near the well opening. One insert rod corresponds to one slot, and the insert rod and the slot fit together.

[0024] By adopting the above technical solution, when the operator activates the pressing component, the pressing component drives the guide rod to push the fixing ring away from the drain pipe. At this time, the insert rod separates from the slot, and the fixing ring separates from the drain pipe. When it is necessary to fix the fixing ring and the drain pipe, simply insert the insert rod into the slot corresponding to the insert rod. By setting the insert rod and slot, it is easy to separate and fix the fixing ring and the drain pipe.

[0025] Optionally, the pressing assembly further includes a conduit. The road body has a connecting groove at the bottom of the pressing groove. The connecting groove is inclined downward from the pressing groove toward the drainage groove. The conduit is located in the connecting groove. One end of the conduit is connected to the pressing groove, and the other end extends into the drainage groove and is connected to the drainage pipe.

[0026] By adopting the above technical solution, when there is heavy rainfall, the rainwater can flow along the road surface and seep into the pressing groove. At this time, the rainwater in the pressing groove flows through the conduit to the drain pipe and is discharged through the drain pipe. By setting the conduit, it is convenient to discharge the rainwater in the pressing groove.

[0027] Optionally, the pressing assembly further includes a protective plate located at the pressing groove. The protective plate is detachably connected to the road body and is used to open or close the pressing groove.

[0028] By adopting the above technical solution, when the pressing part needs to be activated, the personnel only need to open the protective plate, and then the personnel can easily activate the pressing part; by setting the protective plate, it is easy to close the pressing groove, which helps to reduce the situation where rainwater mixed with leaves and gravel falls into the pressing groove.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. Compared with related technologies, this application performs double-layer filtration of rainwater through a second conical filter and a first conical filter, so as to better filter rainwater. By separating the drainage component and the drainage pipe, the filter component can be removed from the drainage tank. Opening the drainage component allows the first and second conical filters to be cleaned, which helps to improve the problem of difficult filter cleaning.

[0031] 2. By setting up a pressing component, it is easy for personnel to separate the fixing ring from the wellhead, and to remove the first and second conical filter screens from the drain pipe, which further helps to improve the problem of difficult filter screen cleaning;

[0032] 3. By setting up a rotating plate, a transmission rod, and a first bevel gear and a second bevel gear, on the one hand, it is convenient to make the first and second conical filter screens rotate; on the other hand, the transmission rod is driven to rotate by rainwater, which is conducive to energy conservation and environmental protection.

[0059] The implementation principle of a road and bridge construction pavement drainage system according to an embodiment of this application is as follows: When it rains, rainwater falls on the road surface. At this time, the drainage component 2 will adjust the position of the fan-shaped adjustment plate 222 according to the amount of water. Then, the rainwater falls into the filter component 3. The filter component 3 can filter the rainwater and the leaves and gravel mixed in the rainwater. At the same time, the rainwater starts the drive component 4. The drive component 4 drives the filter component 3 to move, and the rainwater falls into the drain pipe 11. The rainwater is discharged to the designated location through the drain pipe 11.

[0060] When rainwater is drained, the sensor 24 senses the amount of water and transmits the signal to the drive motor 231. The drive motor 231 drives the fan-shaped adjustment plate 222 to rotate, which can adjust the gap between two adjacent fan-shaped fixed plates 221 to facilitate rainwater drainage. Rainwater falls into the second conical filter screen 33. At the same time, the rainwater impacts the rotating plate 424. Subsequently, the transmission rod 421 drives the rotating shaft 41 to rotate. At this time, the first conical filter screen 32 and the second conical filter screen 33 rotate to filter the rainwater. After that, the rainwater is discharged through the drain pipe 11.

[0061] When it is necessary to clean the first conical filter screen 32 and the second conical filter screen 33, the personnel open the protective plate 54 and press the contact plate 533. At this time, the pressing rod 532 moves towards the bottom of the pressing groove 63, the second spring 534 is compressed, the connecting rod 52 is tilted, and the connecting rod 52 pushes the guide rod 55 to move towards the fixing ring 21. Then, the fixing plate 223 separates from the drain pipe 11, and the cover plate 22, the first conical filter screen 32 and the second conical filter screen 33 are taken out for cleaning. After cleaning is completed, the cover plate 22, the first conical filter screen 32 and the second conical filter screen 33 can be installed.
