Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drainage outlet filtering devices, and particularly relates to a drainage device for filtering and facilitating dredging of a municipal road drainage outlet. BACKGROUND

[0002] The drainage device for filtering and facilitating dredging of a municipal road drainage outlet, namely a rainwater grate, is an open grid-shaped facility installed on a rainwater outlet or drainage ditch, and is mainly used in urban drainage systems. The main function of the rainwater grate is to ensure that rainwater can flow smoothly into the sewer, while blocking larger debris from clogging the sewer. The surface of the rainwater grate is designed with many regularly arranged small holes or grid structures. These holes are small enough to prevent large debris such as leaves and garbage from entering the sewer system, but large enough to allow rainwater to pass through.

[0003] However, after the rain, the debris blocked by the rainwater grate will hang on the rainwater grate, making it very inconvenient for maintenance personnel to clean the rainwater grate. CONTENT OF THE INVENTION

[0004] In view of the deficiencies in the prior art, the present application aims to provide a drainage device for filtering and facilitating dredging of a municipal road drainage outlet, which solves the technical problem that in the prior art, debris blocked by the rainwater grate will hang on the rainwater grate, making it very inconvenient for maintenance personnel to clean the rainwater grate.

[0005] The above-mentioned purpose of the present application is achieved by the following technical solution: a drainage device for filtering and facilitating dredging of a municipal road drainage outlet, comprising a blocking plate, a plurality of water passages formed in the blocking plate and penetrating through the blocking plate, a filling structure arranged at the bottom surface of the blocking plate for filling the water passages, and a control structure arranged on both sides of the filling structure for pulling the filling structure close to the blocking plate, wherein the bottom surface of the blocking plate is provided with a receiving groove for receiving the filling structure.

[0006] Further, the filling structure comprises a filling plate and a plurality of filling blocks arranged on the upper surface and corresponding to the plurality of water passages.

[0007] Further, the control structure comprises two control rods located on both sides of the upper surface of the blocking plate and fixedly connected to the upper surface of the filling plate through the blocking plate, and a limiting ring arranged on the end of the control rod away from the filling plate for preventing the control rod from falling, wherein the control rod is inserted into the blocking plate.

[0008] When the maintenance personnel needs to clean the sundries on the blocking plate, the control rod is pulled to drive the filling plate to move close to the blocking plate and extend into the receiving groove of the blocking plate, at this time, the filling block gradually fills the water passage of the blocking plate, and the sundries hung on the water passage are pushed out by the filling block, so that the maintenance personnel can clean the sundries on the blocking plate as if cleaning the sundries on the flat ground, and the sundries can be gathered by using a cleaning tool and then removed, so that the maintenance personnel can clean the sundries on the blocking plate more conveniently, and the maintenance personnel can also pull the control rod to make the filling block fill the water passage when the rain has not completely receded, so that the sundries pushed out by the filling block are taken away by the rain, making it more convenient for the maintenance personnel to clean the sundries, and after cleaning is completed, the control rod is loosened, and due to the gravity, the blocking plate drives the control rod to move downward until the limiting ring abuts against the blocking plate, so as to reset the blocking plate.

[0009] Further, the end of the control rod away from the filling plate is fixedly provided with a pull ring.

[0010] By adopting the above technical scheme, the control rod is pulled by the maintenance personnel.

[0011] Further, a through hole for rainwater to pass through is formed in the filling plate, the through hole is located between the plurality of filling blocks, and the area of the through hole is greater than the area of the water passage.

[0012] By adopting the above technical scheme, although the setting of the filling structure makes it more convenient for the maintenance personnel to clean the sundries, rainwater falling on the filling plate after passing through the water passage reduces the drainage effect of the municipal road drainage outlet to a certain extent, and the setting of the through hole solves this technical problem, rainwater falling on the filling plate can continue to flow down through the through hole, thereby reducing the influence of the filling plate on the drainage effect of the municipal road drainage outlet, and the area of the through hole being greater than the area of the water passage can prevent sundries from hanging on the filling plate, because the sundries larger than the area of the water passage cannot pass through the water passage, and the sundries smaller than the area of the water passage can pass through the through hole and be discharged.

[0013] Further, the end of the control rod close to the filling structure is provided with a limiting structure for limiting the downward falling of the control rod.

[0014] Further, the limiting structure comprises limiting holes formed in the side edges of the two control rods and penetrating the two control rods, and a limiting rod for penetrating the two control rods through the two limiting holes, and the limiting holes of the two control rods are opposite.

[0015] Through adoption of the above technical scheme, although the control structure is convenient for the maintenance personnel to pull the filling structure to fill the water gap, the maintenance personnel needs to pull the control rod during the cleaning process, so that the maintenance personnel is relatively inconvenient when cleaning the sundries pushed out by the filling structure, and the setting of the limiting structure solves this technical problem, before the maintenance personnel prepares to clean the blocking plate, the maintenance personnel needs to carry the limiting rod to the cleaning site, after reaching the cleaning site, the control rod is pulled to make the filling structure fill the water gap, and then the limiting rod passes through the two control rods through the limiting hole, so that the limiting rod is located between the two control rods, so that the limiting rod abuts against the surface of the blocking plate to prevent the filling structure from falling, so that the filling structure maintains the state of filling the water gap, so that the maintenance personnel does not need to pull the control rod all the time, and the sundries pushed out by the filling structure can also be cleaned.

[0016] Further, the filling plate and the filling block are both made of aluminum alloy material.

[0017] Through adoption of the above technical scheme, the strength and wear resistance of the aluminum alloy are relatively high, the density is about one third of that of steel, and the light characteristic makes it convenient for the maintenance personnel to pull the filling structure, and the wear resistance characteristic makes the service life of the filling structure relatively long.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] Through the setting of the filling structure and the control structure, when the maintenance personnel needs to clean the sundries on the blocking plate, the control rod is only pulled to make the control rod drive the filling plate to approach the blocking plate and extend into the storage groove of the blocking plate, at this time, the filling block will gradually fill the water gap of the blocking plate, and the sundries hung at the water gap will be pushed out by the filling block during the filling process, so that when the maintenance personnel cleans the sundries on the blocking plate, it is like cleaning the sundries on the flat ground, and only the cleaning tool is used to gather the sundries, and the sundries can be shovelled away, so that the maintenance personnel cleans the sundries on the blocking plate more conveniently.

DETAILED DESCRIPTION

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Example, refer to Figure 1 , Figure 2 A drainage device for filtering and facilitating the unblocking of municipal road drainage outlets includes a barrier plate 1 and multiple water inlets 10 formed on and passing through the barrier plate 1, designed to ensure smooth water flow while also providing space for subsequent cleaning work. It also includes a filling structure 2 disposed on the bottom surface of the barrier plate 1 for filling the water inlets 10, and control structures 3 disposed on both sides of the filling structure 2 for pulling the filling structure 2 closer to the barrier plate 1. A storage groove 11 is provided on the bottom surface of the barrier plate 1 to accommodate the filling structure 2.

[0025] It consists of a filling plate 20 and filling blocks 21 precisely positioned on its upper surface corresponding to the positions of each water outlet 10, which are assembled like a collage. Figure 1 Generally, it can quickly fill the sluice gate when needed.

[0026] The control structure 3 includes two robust control rods 30, located on either side of the upper surface of the barrier plate 1. These rods not only pass through the barrier plate 1 and are fixedly connected to the filling plate 20, but also have a limiting ring 31 at their ends away from the filling plate 20. This design not only enhances the stability of the structure but also effectively prevents the control rods 30 from accidentally falling off during operation. The control rods 30 and the barrier plate 1 are connected by a plug-in joint, ensuring a secure connection while facilitating operation by maintenance personnel.

[0027] In practical applications, when municipal road drainage outlets need cleaning, maintenance personnel simply pull two control levers 30, and the filling plate 20 moves closer to the barrier plate 1 and slides smoothly into the pre-designed collection slot 11. During this process, the filling blocks 21 fill the drainage outlets 10 one by one. Their unique shape design allows them to effectively push and clear debris hanging on the edges of the drainage outlets 10 during the filling process, providing maintenance personnel with a flat cleaning platform. Whether using cleaning tools to gather and shovel away debris or using rainwater to wash it away, it becomes exceptionally simple and efficient.

[0028] Of particular note is the device's design, which fully considers both ease of operation and safety. After cleaning is complete, maintenance personnel simply need to release the control lever 30. Using gravity, the barrier plate 1 will cause the control lever 30 to naturally droop until the limit ring 31 gently abuts against the barrier plate 1, thus automatically resetting the filling structure 2. This process requires no additional human intervention, saving time and improving work efficiency.

[0029] In summary, the municipal road drainage outlet filter and facilitate dredging of drainage device, with its unique design concept and efficient performance, greatly improves the work efficiency and safety of maintenance personnel.

[0030] In this embodiment, the control lever 30 is fixed with a pull ring 32 away from the filling plate 20, so as to facilitate the maintenance personnel to pull the control lever 30.

[0031] Although the setting of the filling structure 2 makes it more convenient for maintenance personnel to clean the debris, but the rainwater after passing through the water inlet 10 will fall on the filling plate 20, the filling plate 20 hinders the drainage effect of the municipal road drainage outlet to a certain extent, in order to solve this technical problem, the through hole 22 for rainwater to pass through is set on the filling plate 20, the through hole 22 is located between the plurality of filling blocks 21, the area of the through hole 22 is greater than the area of the water inlet 10, the rainwater falling on the filling plate 20 can continue to flow down through the through hole 22, thereby reducing the influence of the filling plate 20 on the drainage effect of the municipal road drainage outlet, and the area of the through hole 22 is greater than the area of the water inlet 10, which can prevent the debris from hanging on the filling plate 20, because the debris larger than the area of the water inlet 10 cannot pass through the water inlet 10, and the debris smaller than the area of the water inlet 10 can pass through the through hole 22.

[0032] Although the setting of the control structure 3 is convenient for the maintenance personnel to pull the filling structure 2 to fill the water inlet 10, but in the process of cleaning, the maintenance personnel need to pull the control lever 30 all the time, so that the maintenance personnel is more inconvenient when cleaning the debris pushed out by the filling structure 2, in order to solve this technical problem, the limiting structure 4 for limiting the control lever 30 from falling down is arranged at the end of the control lever 30 close to the filling structure 2, the limiting structure 4 includes the limiting hole 40 arranged on the side of the two control levers 30 and penetrating the two control levers 30 and the limiting rod 41 for penetrating the two control levers 30 through the two limiting holes 40, the limiting holes 40 of the two control levers 30 are opposite, the maintenance personnel need to carry the limiting rod 41 to the cleaning site before preparing to clean the blocking plate 1, after reaching the cleaning site, pull the control lever 30 to make the filling structure 2 fill the water inlet 10, then pass the two control levers 30 through the limiting holes 40 with the limiting rod 41, so that the limiting rod 41 is located between the two control levers 30, so that the limiting rod 41 abuts against the surface of the blocking plate 1 to prevent the filling structure 2 from falling down when the filling structure 2 falls with the control lever 30, so that the filling structure 2 maintains the state of filling the water inlet 10, so that the maintenance personnel can clean the debris pushed out by the filling structure 2 without pulling the control lever 30 all the time.

[0033] In this embodiment, the patch plate 20 and the patch block 21 are both made of aluminum alloy material, the aluminum alloy has high strength and wear resistance, the density is about one third of steel, the lighter characteristics make the maintenance personnel easy to pull the patch structure 2, the wear-resistant characteristics make the service life of the patch structure 2 longer.

[0034] Specific implementation process: before the maintenance personnel need to clean the sundries on the blocking plate 1, carry the limiting rod 41 to the cleaning site, after arriving at the cleaning site, pull the control rod 30 to make the control rod 30 drive the patch plate 20 to close to the blocking plate 1 and extend into the storage groove 11 of the blocking plate 1, at this time the patch block 21 will gradually fill the water gap 10 of the blocking plate 1, in the process of filling, the sundries hanging at the water gap 10 will be pushed out by the patch block 21, then the limiting rod 41 passes through the limiting hole 40 through the two control rods 30, so that the limiting rod 41 is located between the two control rods 30, so that the patch structure 2 falls with the control rod 30, the limiting rod 41 will abut against the surface of the blocking plate 1 to prevent the patch structure 2 from falling, so that the patch structure 2 maintains the state of filling the water gap 10, at this time the maintenance personnel only need to use the cleaning tool to gather the sundries and shovel away.

[0035] The embodiments of the specific implementation are the preferred embodiments of the application, not limited to the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
