[0002] Municipal bridges are structures that allow vehicles and pedestrians to pass smoothly. As an important part of urban transportation, their drainage performance is directly related to the service life of the bridge and driving safety.

[0003] At present, the drainage of municipal bridges is generally achieved through drainage devices, which transport the water on the bridge to the drainage system. Since there are impurities such as branches and soil on the surface of the bridge, blockage problems are prone to occur during the drainage process. In related technologies, grates are generally set to play a filtering role to reduce the flow of impurities into the drainage device.

[0004] However, the grate can only play a certain preventive role. When mud and other materials are deposited and accumulated, the drainage device may still be blocked.

[0025] Optionally, a filter portion is provided at the bottom of the carrier, and the filter portion is used to filter impurities in water.

[0026] By adopting the above technical solution, after rainwater flows into the bottom of the second filter element, it can be further filtered through the supporting member, limiting the location where blockage occurs below the second filter element, allowing impurities to adhere to the filter portion and become blocked on the supporting member, thereby reducing the risk of blockage below the supporting member, thereby achieving effective cleaning by removing the supporting member, thereby increasing the success rate of blockage resolution.

The first connecting member of the first cleaning mechanism is used to connect the bearing member, and the bearing member is used to filter the rainwater again to improve the cleanliness of the rainwater flowing into the embedded pipe, so that when the second filter element moves, the bearing member can be driven to the top of the first filter element. It is convenient to clean the impurities filtered out in the bearing member. The first cleaning mechanism is moved out as a whole, without reaching into the connecting pipe and removing the first filter element, thereby reducing the pulling strength and cleaning difficulty. When blockage occurs, the water level in the embedded pipe and the connecting pipe continues to rise, which can make the floating member float up. Under the action of the sliding rod and the sliding guide of the slide groove, the floating member drives the indicator member to move upward until the indicator member passes through the second through hole on the second filter element. The protrusion of the indicator member indicates the occurrence of blockage, avoiding the influence of excessive rainwater on the judgment of whether there is blockage.

When the floating member floats up, the vertical rod is used to pass through the second through hole, driving the flexible member to reliably pass through the second through hole. After the flexible member protrudes from the surface of the second filter member, its flexibility can avoid affecting pedestrians and vehicles on the bridge body. At the same time, the flexible member can float with the water. Through its dynamic changes, the possibility of the flexible member being discovered is increased, thereby improving the timeliness of discovering the blockage; 3. In the process of moving the first cleaning mechanism upward, the cleaning component can be moved to the top of the first through hole by driving the transmission component to move, so that after the first cleaning mechanism is completely moved out, the cleaning component cover is set on the first through hole to avoid the first through hole being completely exposed when cleaning the first cleaning mechanism, which will cause safety hazards to pedestrians and vehicles.

[0035] The following is combined with Figure 1 -Attached Figure 6 The present application is further described in detail. In this embodiment, if not clearly specified, "connected", "connected" and "fixed" are understood in a broad sense, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection and interaction between two elements, etc., which can be understood according to the specific circumstances. In the absence of any contrary explanation, the directional words used in this application, such as "inside" and "outside", refer to the outline of the corresponding parts themselves.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application discloses a municipal bridge drainage device (hereinafter referred to as "device"). The device is arranged on the bridge body 100, and includes a pre-buried pipe 1, a filter mechanism 2, a first cleaning mechanism 3 and an indication mechanism 4. The pre-buried pipe 1 is buried in the bridge body 100, so that one end of the pre-buried pipe 1 is connected to the filter mechanism 2, and the other end is connected to the drain pipe, so that rainwater and other liquids on the bridge body 100 are input into the pre-buried pipe 1 through the filter mechanism 2, and further discharged to the drain pipe of the drainage system through the pre-buried pipe 1, so as to achieve the drainage of the bridge body 100. In this embodiment, the drainage of rainwater is introduced as an example. Through the filtering of the filter mechanism 2 of the device, the cleaning of impurities by the first cleaning mechanism 3, and the timely prompting of the occurrence of blockage by the indication mechanism 4, the purpose of reducing the risk of blockage of the pre-buried pipe 1 and the drain pipe below it, reducing the difficulty of cleaning and timely cleaning is achieved.

[0037] like Figure 3 , Figure 4 and Figure 5As shown, the filter mechanism 2 includes a first filter element 21, a connecting pipe 22 and a second filter element 23. The first filter element 21 is arranged on the upper surface of the bridge body 100, and the connecting pipe 22 is arranged below the first filter element 21. The two ends of the connecting pipe 22 are respectively connected to the first filter element 21 and the embedded pipe 1, so that rainwater on the bridge body 100 can flow into the connecting pipe 22 through the first filter element 21, and further flow into the embedded pipe 1. The first filter element 21 is provided with a first through hole 211 and a plurality of first drain ports 212. The first through hole 211 is arranged at the center of the first filter element 21, and the first drain ports 212 are distributed around the first through hole 211. The first drain ports 212 are used to allow rainwater to flow into the connecting pipe 22. The side wall of the first through hole 211 is provided with a step portion 213, which can be a plurality of block structures, and the plurality of step portions 213 are circumferentially distributed on the side wall of the first through hole 211; the step portion 213 can also be an annular structure, the outer periphery of the annular structure is connected to the side wall of the first through hole 211, and the step portion 213 is used to set up the second filter element 23 so that the second filter element 23 is assembled and connected with the first filter element 21.

[0038] The second filter element 23 is provided with a second drain port 233, through which rainwater can flow into the connecting pipe 22 below the second filter element 23. Preliminary filtration is performed by the first filter element 21 provided with the first drain port 212 and the second filter element 23 provided with the second drain port 233, thereby reducing the possibility of impurities such as large branches entering the connecting pipe 22 and the embedded pipe 1, and reducing the risk of clogging the embedded pipe 1 or the drainage pipe. The second filter element 23 is detachably connected to the step portion 213, so as to facilitate the removal of the second filter element 23 and the cleaning of the area below the first filter element 21. Both the first filter element 21 and the second filter element 23 can be plate-like structures, the first drain port 212 and the second drain port 233 are vertically extending through holes, the diameters of the first drain port 212 and the second drain port 233 are determined according to actual conditions, the shape of the second filter element 23 matches the shape of the first through hole 211, and the shape of the first filter element 21 is set as required. The connecting pipe 22 can be a funnel-shaped structure or a hollow straight tube structure, which can connect the first filter element 21 and the embedded pipe 1 to transport rainwater on the bridge body 100 to the embedded pipe 1.

[0039] like Figure 3 and Figure 6As shown, the first cleaning mechanism 3 is arranged below the second filter element 23. The first cleaning mechanism 3 includes a bearing member 31 and a plurality of first connecting members 32. The two ends of the first connecting member 32 are respectively connected to the second filter element 23 and the bearing member 31. The bearing member 31 is used to carry impurities in the water. By filtering the rainwater again, the cleanliness of the rainwater flowing into the pre-buried pipe 1 is improved. The first connecting member 32 can be a rod-shaped structure or a plate-shaped structure, the upper end of which is connected to the second filter element 23 and the lower end is connected to the bearing member 31, so that when the second filter element 23 is disassembled, the bearing member 31 can be driven to move synchronously, which is convenient for cleaning the impurities filtered out of the bearing member 31. The method of removing the first cleaning mechanism 3 as a whole does not require extending into the interior of the connecting pipe 22 and does not require removing the first filter element 21, which can reduce the difficulty of cleaning and the pulling force required for removal.

[0040] The support member 31 may be a bowl-shaped structure, and a filter portion is provided at the bottom of the bowl-shaped structure, and the filter portion is used to filter impurities in the water. The filter portion is a plate member provided with a plurality of through holes, and the diameter of the through holes is smaller than the diameter of the first drain port 212 and the second drain port 233, so as to achieve further filtration. After the rainwater flows into the bottom of the second filter element 23, it can be further filtered through the support member 31, and the blockage position under the second filter element 23 is limited, so that impurities can adhere to the filter portion, and the blockage position is easily concentrated on the support member 31, reducing the risk of blockage under the support member 31, so that the blockage position can be effectively cleaned by removing the support member 31, thereby improving the success rate of blockage resolution.

[0041] like Figure 3 and Figure 6As shown, the indicating mechanism 4 includes an indicating member, a floating member 42 and a plurality of sliding rods 43. A slide groove 321 is provided on the first connecting member 32, and the sliding rod 43 corresponds to the slide groove 321 one by one. In this embodiment, two first connecting members 32 are provided, and the two first connecting members 32 are symmetrically arranged on both sides of the bearing member 31. The bearing member 31 is fixedly connected to the first connecting member 32. The bearing member 31 can be connected to the lower end of the first connecting member 32, or it can be connected to the upper part of the lower end of the first connecting member 32. The bearing member 31 can be arranged below the second filter member 23. Each first connecting member 32 is provided with a vertically extending slide groove 321, and the slide groove 321 extends downward from the upper end of the first connecting member 32 by a certain distance, so that the slide groove 321 is located above the bearing member 31. One end of the sliding rod 43 is slidably connected to the slide groove 321, and the other end of the sliding rod 43 is connected to the floating member 42. A plurality of sliding rods 43 are evenly distributed around the floating member 42, so that the floating member 42 can only move in the vertical direction. The floating member 42 can be a hollow ball made of rubber or plastic material, or other structures that can float under the buoyancy of rainwater. The top of the floating member 42 is connected to the indicator, and the second filter 23 is provided with a second through hole 231. The floating member 42 can drive the indicator to pass through the second through hole 231 upward, and the indicator is used to indicate the blockage of the connecting pipe 22 or the embedded pipe 1.

[0042] When a blockage occurs, the water level in the embedded pipe 1 and the connecting pipe 22 will continue to rise. After rising to the moving height, the floating member 42 can float up. Under the action of the sliding guide of the sliding rod 43 and the slide groove 321, the floating member 42 drives the indicator to move vertically upward until the indicator passes through the second through hole 231. The protrusion of the indicator indicates the occurrence of blockage, avoiding the judgment of whether there is a blockage due to excessive rainwater on the bridge body 100; and the indicator can also facilitate the rapid and accurate positioning of the device when there is a lot of rainwater on the bridge body 100, so as to improve the cleaning efficiency; the indicator can be coated with a striking color to optimize the prompt effect. The longitudinal section of the sliding rod 43 is rectangular, and the shape of the slide groove 321 matches the sliding rod 43 to avoid the floating member 42 rotating around the sliding rod 43 so that the indicator cannot be aligned with the second through hole 231.

[0043] like Figure 3 and Figure 6As shown, optionally, the indicator includes a vertical rod 411 and a flexible member 412. One end of the vertical rod 411 is connected to the top of the floating member 42, and the flexible member 412 is arranged at the upper end of the vertical rod 411. The vertical rod 411 is penetrated through the second through hole 231, so that the flexible member 412 extends above the second filter 23. The vertical rod 411 is a rigid rod. When the floating member 42 floats, the vertical rod 411 is used to pass through the second through hole 231, thereby driving the flexible member 412 to reliably pass through the second through hole 231. The highest position of the top of the vertical rod 411 can be flush with the upper surface of the second filter 23, so as to avoid the safety hazard caused by the rigid vertical rod 411 extending out. The flexible member 412 can be a structure with certain flexibility and can float in water, such as sponge, cloth or rope, so that after the flexible member 412 protrudes from the surface of the second filter 23, its flexibility can avoid affecting pedestrians and vehicles on the bridge body 100. At the same time, the flexible member 412 can float with the water, and through its dynamic changes, the possibility of the flexible member 412 being discovered is increased, thereby improving the timeliness of discovering the blockage. The diameter of the second through hole 231 is greater than or equal to the diameter of the vertical rod 411, so that the vertical rod 411 can penetrate into the second through hole 231.

[0044] like Figure 2 , Figure 3 and Figure 6 As shown, optionally, a handle 232 is provided on the second filter element 23. The handle 232 is provided on one side of the second through hole 231, and the handle 232 is used to drive the second filter element 23 to disengage from the step portion 213. One or two handles 232 can be provided to reduce the difficulty of operation when lifting the second filter element 23. By pulling the handle 232, the second filter element 23 and the first cleaning mechanism 3 thereunder are driven to move upward as a whole, thereby reducing the difficulty of cleaning. The handle 232 can be a U-shaped structure, and is rotatably connected to the second filter element 23 through the two ends of the U-shaped structure. When not in use, the handle 232 is horizontally placed on the second filter element 23 and is located on one side of the second through hole 231 to avoid affecting the extension of the indicator; when the second filter element 23 needs to be lifted, the handle 232 is rotated to a vertical state to achieve lifting.

[0045] Optionally, the device further includes a second cleaning mechanism 5, which includes a cleaning assembly and a transmission assembly. The cleaning assembly is disposed on the bridge body 100, the cleaning assembly is located on both sides of the first filter element 21, the transmission assembly is connected to the cleaning assembly, and the first cleaning mechanism 3 is selectively connected to the transmission assembly. In the process of moving the first cleaning mechanism 3 upward, the second filter element 23 drives the supporting element 31 upward, so that the supporting element 31 drives the cleaning assembly to move horizontally to above the first through hole 211 through the transmission assembly, so that after the first cleaning mechanism 3 is completely moved out, the cleaning assembly cover is disposed on the first through hole 211, so as to avoid the first through hole 211 being completely exposed when cleaning the first cleaning mechanism 3, thereby causing a safety hazard to pedestrians and vehicles.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the cleaning assembly includes a first cleaning plate 51 and a second cleaning plate 52, and the first cleaning plate 51 and the second cleaning plate 52 are respectively arranged on two symmetrical sides of the first filter element 21. The transmission assembly is respectively connected to the first end of the first cleaning plate 51 away from the first filter element 21 and the first end of the second cleaning plate 52 away from the first filter element 21, and the transmission assembly is used to drive the first cleaning plate 51 and the second cleaning plate 52 to move toward each other, so that the first cleaning plate 51 and the second cleaning plate 52 are stacked on the first filter element 21. The second cleaning plate 52 is used to block the first through hole 211; the first cleaning plate 51 is detachably connected to the transmission assembly, and the first cleaning plate 51 is used to remove impurities. The first cleaning mechanism 3 drives the second cleaning plate 52 and the first cleaning plate 51 to be stacked up and down, so that the second cleaning plate 52 of the lower layer can cover the first through hole 211 to prevent impurities from flowing into the connecting pipe 22; the first cleaning plate 51 located on the upper layer is detachably connected to the transmission assembly, so that the first cleaning plate 51 can be removed. When there is too much rain and water accumulates on the bridge body 100, the first cleaning plate 51 is used to clean impurities around the first filter element 21, thereby reducing impurities around the device and preventing impurities from pouring into the connecting pipe 22 when the second cleaning plate 52 is opened.

[0047] Optionally, a plurality of blocking bars 53 are provided on the first cleaning plate 51 and the second cleaning plate 52, and the blocking bars 53 are used to block impurities. In the initial state of the second cleaning mechanism 5, the blocking bars 53 on the first cleaning plate 51 and the second cleaning plate 52 located on both sides of the first filter element 21 can block impurities in the rainwater flowing into the connecting pipe 22, reduce impurities flowing onto the first filter element 21, and reduce the risk of clogging of the pre-buried pipe 1 and other pipelines.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, a first guide groove 110 and a second guide groove 120 are provided on the bridge body 100, and the first guide groove 110 and the second guide groove 120 are respectively provided on both sides of the first filter element 21. A first leg is detachably connected to the lower side of the first end of the first cleaning plate 51, and a second leg is provided to the lower side of the first end of the second cleaning plate 52, and the first leg is slidably connected to the first guide groove 110, and the second leg is slidably connected to the second guide groove 120.

[0049] In the present embodiment, two first guide grooves 110 and two second guide grooves 120 are provided, the two first guide grooves 110 are parallel to each other and arranged horizontally at intervals, and the two second guide grooves 120 are parallel to each other and arranged horizontally at intervals. Two first legs and two second legs are provided respectively, the first legs correspond to the first guide grooves 110 one by one, and the second legs correspond to the second guide grooves 120 one by one. The first legs and the second legs can be columnar structures, and the lower ends of the first legs and the second legs can be spherical surfaces, so that when the transmission assembly pulls the first cleaning plate 51 and the second cleaning plate 52, it can be easy to slide in the first guide groove 110 and the second guide groove 120 to reduce friction resistance. There can be a certain vertical relative movement between the first leg and the first guide groove 110, and between the second leg and the second guide groove 120, so that the first cleaning plate 51 and the second cleaning plate 52 can be stacked. The first leg and the end surface of the first guide groove 110 close to the first filter element 21 are used to limit the movement position of the first cleaning plate 51, so as to prevent the first cleaning plate 51 from moving too much and being unable to cover the first filter element 21; the second leg and the end surface of the second guide groove 120 close to the first filter element 21 are used to limit the movement position of the second cleaning plate 52, so as to prevent the second cleaning plate 52 from moving too much and being unable to completely cover the first through hole 211, causing impurities to flow into the first through hole 211, affecting the cleaning effect and anti-blocking effect. The lower ends of the first leg and the second leg can be provided with a certain clamping structure, so that the first leg will not fall out of the first guide groove 110 and the second leg will not fall out of the second guide groove 120. A vertical limiting structure can also be provided above one side of the first cleaning plate 51 and the second cleaning plate 52, so as to prevent the first cleaning plate 51 and the second cleaning plate 52 from flipping over when the transmission assembly drives the cleaning assembly to move, thereby affecting the use.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, the cooperation between the first guide groove 110 and the first leg enables the first cleaning plate 51 to move in a straight line toward the first filter element 21 when being pulled, and the cooperation between the second guide groove 120 and the second leg enables the second cleaning plate 52 to move in a straight line toward the first filter element 21 when being pulled. In the initial state, the horizontal distance between the first cleaning plate 51 and the second cleaning plate 52 and the first filter element 21 can be set as needed, so that after the support member 31 moves to the top of the second filter element 23, the first cleaning plate 51 and the second cleaning plate 52 can be stacked on the first through hole 211.

[0051] The height of the first leg is greater than the height of the second leg. The first cleaning plate 51 is provided with a first transition portion 511 at the second end near the first filter element 21, and the second cleaning plate 52 is provided with a second transition portion 521 at the second end near the first filter element 21. The first transition portion 511 cooperates with the second transition portion 521 so that the first cleaning plate 51 can slide above the second cleaning plate 52. When the first cleaning plate 51 and the second cleaning plate 52 move relative to each other until they are in contact, the first cleaning plate 51 can move above the second cleaning plate 52 through the cooperation of the first transition portion 511 and the second transition portion 521. Since the height of the first leg is greater than the height of the second leg, it is helpful to ensure that the first cleaning plate 51, which has risen in vertical height, is still guided by the first guide groove 110, thereby improving the reliability of the first cleaning plate 51 and the second cleaning plate 52 when they are stacked. The detachable connection of the first leg helps to disengage the first cleaning plate 51 from the first guide groove 110, so that the first cleaning plate 51 can be used to clean impurities.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, the first transition portion 511 includes a first inclined surface, which extends upward from the bottom of the end surface of the second end of the first cleaning plate 51 in a direction close to the first filter element 21 until it extends to the upper surface of the first cleaning plate 51; the second transition portion 521 includes a second inclined surface and a third inclined surface, so that the second end surface of the second cleaning plate 52, the second inclined surface and the third inclined surface form a triangular structure, and the connection position of the second inclined surface and the third inclined surface in the vertical direction is located in the middle of the first inclined surface, so that after the second transition portion 521 contacts the first transition portion 511, the first cleaning plate 51 can slide to the top of the second cleaning plate 52. The first transition portion 511 and the second transition portion 521 can both be provided with rounded corners or chamfers to improve safety during use and avoid scratches and the problem of relative sliding stacking after contact.

[0053] like Figure 1 , Figure 2 and Figure 4 As shown, optionally, the transmission assembly includes a first transmission member 54, a second transmission member 55, and a second connecting member 56. The first end of the first transmission member 54 is rotatably connected to the first end of the first cleaning plate 51, the first end of the second transmission member 55 is rotatably connected to the first end of the second cleaning plate 52, and the second end of the first transmission member 54 and the second end of the second transmission member 55 are rotatably connected through the second connecting member 56. The first cleaning mechanism 3 is used to lift the second connecting member 56, so that the second connecting member 56 drives the first cleaning plate 51 and the second cleaning plate 52 to move toward each other through the first transmission member 54 and the second transmission member 55.

[0054] Since the second end of the first transmission member 54 and the second connecting member 56, the second end of the second transmission member 55 and the second connecting member 56, the first end of the first transmission member 54 and the first cleaning plate 51, and the first end of the second transmission member 55 and the second cleaning plate 52 are all rotatably connected, when the first cleaning mechanism 3 lifts the second connecting member 56, the second connecting member 56 can drive the first end of the first transmission member 54 and the first end of the second transmission member 55 to move upward, so that the first transmission member 54 and the second transmission member 55 are both tilted. Since the first transmission member 54 and the second transmission member 55 are arranged on both sides of the second connecting member 56, the first transmission member 54 and the second transmission member 55 can be tilted in opposite directions, so that the first cleaning plate 51 and the second cleaning plate 52 can be provided with horizontal forces in opposite directions, pulling the first cleaning plate 51 and the second cleaning plate 52 to move toward each other, thereby achieving stacking.

[0055] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the first transmission member 54, the second transmission member 55 and the second connecting member 56 are rod-shaped structures or ropes with hooks or rings at both ends, and the hook connection is realized by the hook or the connection is realized by the structure similar to the nine-linked rings set mutually by the rings, so that relative rotation can be realized. In this embodiment, taking the rod-shaped structure with hooks at both ends as an example, the first end of the first cleaning plate 51 and the first end of the second cleaning plate 52 can be provided with a cylindrical rod, so that the hook can be hooked to the cylindrical rod to realize relative rotation. The hook setting mode is also convenient for removing the first cleaning plate 51. The specific structure of the hook can be selected according to the actual use. The middle part of the second connecting member 56 can be provided with a clamping part, which is used to cooperate with the bearing member 31 to realize the alignment clamping, so as to avoid the second connecting member 56 from sliding horizontally. The middle part of the rod-shaped structure of the second connecting member 56 can be set as a bendable structure, so that the bearing member 31 is clamped to the middle part of the rod-shaped structure and bends, so as to avoid the second connecting member 56 from moving horizontally. The length of the second connecting member 56 can be smaller than that of the first transmission member 54 and the second transmission member 55, and the second connecting member 56 may not even be provided, so that the first transmission member 54 and the second transmission member 55 can be directly rotatably connected. However, at this time, when the supporting member 31 drives the transmission assembly, it is not easy to achieve reliable support and lifting of the transmission assembly. The clamping connection between the second connecting member 56 and the supporting member 31 helps to reliably drive the transmission assembly to rise, and then drive the cleaning assembly to move.

[0056] like Figure 2 , Figure 3 and Figure 6As shown, optionally, a protrusion 311 is provided on the carrier 31, and a avoidance groove is provided on the first filter 21 so that the protrusion 311 can pass through. The protrusion 311 can be clamped with the second connecting member 56, and the protrusion 311 is used to drive the second connecting member 56 to move. A clamping groove can be provided on the protrusion 311, and the cross-sectional shape of the clamping groove matches the second connecting member 56. When the carrier 31 moves up to the upper surface of the first filter 21, the clamping groove of the protrusion 311 can be used to realize the clamping with the second connecting member 56, thereby driving the second connecting member 56 to move up, and then driving the first transmission member 54 and the second transmission member 55 to move, so as to realize the pulling of the first cleaning plate 51 and the second cleaning plate 52. The horizontal distance between the first cleaning plate 51 and the second cleaning plate 52 and the first filter 21 is set as required, so that after the carrier 31 moves to the top of the first filter 21, the first cleaning plate 51 and the second cleaning plate 52 come into contact.

[0057] It can be understood that the device also includes necessary structures for connection, support, limitation, avoidance, driving and control so that the device can operate normally; the shape, size, setting quantity and other parameters of each part of the device can be determined as needed to achieve the corresponding functions.

[0058] The implementation principle of a municipal bridge drainage device in the embodiment of the present application is as follows: when no blockage occurs, rainwater can pass through the filtering effect of the first filter element 21, the second filter element 23 and the supporting element 31, thereby reducing the impurities flowing into the embedded pipe 1 and reducing the risk of blockage; when blockage occurs, the floating element 42 floats up under the buoyancy of rainwater, so that the vertical rod 411 passes through the second through hole 231, and the flexible element 412 extends and floats with the water, which is used to indicate the blockage and locate the position of the device so as to quickly and accurately find the drainage position; the handle 232 is pulled to drive the second filter element 23 and the first cleaning mechanism 3 to move upward, and the impurities deposited in the supporting element 31 are removed. The second cleaning plate 51 and the second cleaning plate 52 can be moved toward each other and stacked through the movement of the first transmission member 54 and the second transmission member 55, so that when cleaning the carrier 31, the second cleaning plate 52 can block the second through hole 231, and the first cleaning plate 51 can clean the surrounding impurities, thereby optimizing the cleaning effect. After cleaning, the second filter element 23, the second cleaning mechanism 5 and the first cleaning mechanism 3 can be reset respectively.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
