Description

Technical Field

[0001] The present application relates to the technical field of drainage facilities, and in particular to a filter manhole cover for school drainage channels. Background Art

[0002] Drainage channels are facilities set up on the roadside or the edge of a house to guide rainwater and discharge it into rainwater wells. Drainage channels are usually recessed downwards. In order to prevent the drainage channels from affecting pedestrians, permeable manhole covers are usually installed above the drainage channels so that rainwater can flow through the manhole covers into the drainage channels, while also allowing pedestrians to walk.

[0003] Usually, schools have very good green areas, so there will be a lot of fallen leaves. On rainy days, a large number of fallen leaves will flow into the drains along with the rainwater, which can easily lead to blockage of the drains. After the drains are blocked, it is necessary to open the manhole covers and clean the inside of the drains. After the fallen leaves fall into the drains, they will not only land in a few locations of the drains, but will be distributed in various locations of the drains. Therefore, when cleaning, the entire drain must be cleaned to clean the fallen leaves in the drains, which makes the cleaning of fallen leaves too troublesome.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In order to make it easier to clean up debris such as fallen leaves in the drainage channel, the present application provides a filter manhole cover for the school drainage channel.

[0006] This application provides a filter manhole cover for a school drainage ditch, which adopts the following technical solution:

[0007] A filter manhole cover for a school drainage channel includes a cover body for covering the drainage channel, the cover body is provided with a plurality of drainage holes for passing liquid, a water filter frame for filtering fallen leaves is provided below the cover body, the water filter frame is arranged with an upper opening, the upper end opening of the water filter frame is simultaneously connected to all the drainage holes on the cover body, and the height of the water filter frame is less than the depth of the drainage channel.

[0008] By adopting the above technical solution, when the fallen leaves flow into the drain channel with the water flow, the fallen leaves and water will enter the water filter frame through the drainage holes. Then the water will continue to flow downward through the holes on the water filter frame and enter the drain channel for discharge, while the fallen leaves and other debris will be retained in the water filter frame. During subsequent cleaning, it is only necessary to directly remove the fallen leaves in the water filter frame to complete the cleaning without the need to clean the entire drain channel.

[0009] Optionally, a side wall at the upper end of the water filter frame is rotatably connected to the cover body.

[0010] By adopting the above technical solution, when it is necessary to clean the fallen leaves in the water filter frame, the cover body can be directly rotated upward to open the opening at the upper end of the water filter frame, and then the fallen leaves can be removed from the water filter frame through the opening at the upper end of the water filter frame, making the cleaning of the fallen leaves in the water filter frame more convenient.

[0011] Optional: The upper end of the water filter frame is provided with a number of sliders for horizontal sliding, and each slider is rotatably connected to a rotating rod, and the end of the rotating rod away from the water filter frame is rotatably connected to the cover body, and the upper end of the water filter frame is provided with an extension bar, and the extension bar can be set in a groove where the cover body is placed on the drain channel.

[0012] By adopting the above technical solution, when the upper end of the water filter frame needs to be opened, the cover body can be directly rotated upward. During the rotation of the cover body, the slider will move horizontally, so that the groove on the drain channel where the cover body is placed will not hinder the rotation of the cover body. The cover body can be rotated when the water filter frame is placed in the drain channel, making it more convenient to clean the fallen leaves and other debris in the water filter frame.

[0013] Optional: The water filter frame is provided with a limit assembly for limiting its relative rotation with the cover body, and the limit assembly is arranged on the side of the water filter frame away from its own rotation axis. The limit assembly includes a connecting rod rotatably connected to the top of the water filter frame, a limit block arranged on the connecting rod, and a limit elastic member for driving the connecting rod to rotate. A limit groove is provided on the inner wall of the drainage hole of the cover body, and the limit block is embedded in the limit groove.

[0014] By adopting the above technical solution, when there is no need for the cover body to move relative to the water filter frame, the limit block can be inserted into the limit groove, so that the relative position between the cover body and the water filter frame can be limited, so that the cover body can be stably covered on the water filter frame, and the cover body and the water filter frame can be directly removed from the drain channel by applying force to the cover body.

[0015] Optionally, an extension piece is provided at the upper end of the limit block, and the upper end of the extension piece is provided lower than the upper end surface of the cover body.

[0016] By adopting the above technical solution, when the limit block needs to be rotated, insert your finger into the drain hole to apply force to the extension piece, so that the rotating rod rotates away from the side wall to which it is connected, so that the limit block is disengaged from the limit groove, so that the cover plate is not restricted when rotating, and the rotation of the cover plate is more convenient.

[0017] Optionally, a receiving groove is provided at the upper end of the cover body, and a handle that can be rotatably connected to the receiving groove and can be sunk into the receiving groove is provided.

[0018] By adopting the above technical solution, when it is necessary to rotate the limit block and rotate the cover body upward, by holding the handle and pressing the extension piece, force can also be applied to the handle in the process of applying force to the extension piece to drive the cover body to rotate, so that the cover body can be rotated with only one hand.

[0019] Optionally, the handle is arranged on a side of the limiting block close to the rotation axis of the water filter frame, and the handle is arranged close to the limiting assembly.

[0020] By adopting the above technical solution, the handle and the limit assembly can be operated by one hand, making the opening process of the cover more convenient.

[0021] Optionally, a plurality of hooks are provided on the inner wall of the water filter frame, a filter screen is provided in the water filter frame (2), and the upper end of the filter screen is hung on the hooks.

[0022] By adopting the above technical solution, the fallen leaves in the water filter frame are collected and filtered using a filter. When cleaning is needed, the filter can be directly taken out from the water filter frame and the fallen leaves in the filter can be poured out. The filter can then be placed in the water filter frame. This allows the fallen leaves in the water filter frame to be cleaned at one time, making the cleaning process more convenient.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When fallen leaves flow into the drain channel with the water flow, the fallen leaves and water will enter the water filter frame through the drainage holes. Then the water will continue to flow downward through the holes on the water filter frame and enter the drain channel for discharge, while the fallen leaves and other debris will be retained in the water filter frame. When cleaning later, you only need to remove the fallen leaves in the water filter frame to complete the cleaning, without having to clean the entire drain channel.

[0025] 2. Use the filter to collect and filter the fallen leaves in the water filter frame. When cleaning is needed, the filter can be directly taken out from the water filter frame and the fallen leaves in the filter can be dumped out. Then the filter can be placed in the water filter frame. In this way, the fallen leaves in the water filter frame can be cleaned at one time, making the cleaning process of the fallen leaves more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] The present application discloses a filter manhole cover for a school drainage ditch, such as Figure 1 As shown, the device comprises a cover 1 for covering a drain channel. The upper end surface of the cover 1 is penetrated by a plurality of drainage holes 11. The drainage holes 11 are arranged perpendicular to the width of the cover 1 and arranged along the length of the cover 1. When the cover 1 is placed on the drain channel, the cover 1 is arranged along its own length, and adjacent covers 1 abut against each other. A water filter frame 2 for filtering fallen leaves is provided at the lower end of the cover 1. The water filter frame 2 is arranged with an upper opening. The drainage holes 11 on the cover 1 connected to the water filter frame 2 are all projected on a horizontal plane within the water filter frame 2, so that fallen leaves moving downward through the drainage holes 11 can all fall into the water filter frame 2. The projection of the water filter frame 2 on the horizontal plane is located within the projection of the cover body 1 on the horizontal plane. A gap is left between the outer wall of the water filter frame 2 and the four side walls of the cover body 1. Therefore, after adjacent covers 1 abut each other, the water filter frames 2 between adjacent covers 1 will not come into contact with each other, so that the water filter frames 2 and covers 1 will not be blocked when they are subsequently removed from the drainage channel. When the road drainage is poor, only the covers 1 in the poorly drained area need to be opened directly to clean the fallen leaves in the water filter frame 2.

[0033] like Figure 2 As shown, the upper ends of both side walls of the water filter frame 2, parallel to the length of the cover 1, are integrally formed with extension strips 21. The upper end of the extension strips 21 is flush with the upper end of the water filter frame 2. The extension strips 21 fit within the groove of the drain channel in which the cover 1 is placed, and the lower end of the cover 1 abuts against the upper ends of the extension strips 21. Two sliders 22 are horizontally slidably mounted on the inner wall of the water filter frame 2. These sliders 22 are positioned on two inner walls of the water filter frame 2 that are spaced apart from each other, and are arranged parallel to the length of the cover 1. A pivoting rod 23 is pivotally connected to the adjacent side walls of the sliders 22. The upper end of the pivoting rod 23 is pivotally connected to the lower end of the cover 1, allowing the cover 1 to be directly attached to the water filter frame 2. This also allows the cover 1 to be rotated upward without removing it from the groove of the drain channel, making it easier to clean debris such as fallen leaves from the water filter frame 2.

[0034] like Figure 3 As shown, in order to allow both the cover body 1 and the water filter frame 2 to be removed simultaneously from the drain channel, the water filter frame 2 is further provided with a stopper assembly 3 that defines the relative position between the cover body 1 and the water filter frame 2. The stopper assembly 3 is disposed on the side of the water filter frame 2 away from its own rotation axis. The stopper assembly 3 includes a connecting rod 31 rotatably connected to the inner wall of the water filter frame 2, a stopper block 32 disposed at the upper end of the connecting rod 31, and a stopper elastic member 33 that drives the connecting rod 31 to rotate. The connecting rod 31 is vertically disposed, with its upper end extending through a drain hole 11 and its upper end lower than the upper end surface of the cover body 1. A stopper groove 12 is also defined on the inner wall of the drain hole 11 for receiving the connecting rod 31. The stopper block 32 can be embedded in the stopper groove 12, thereby defining the relative position between the cover body 1 and the water filter frame 2. In this embodiment, the limiting elastic member 33 is a torsion spring, which is arranged on the connecting rod 31, and the rotation axis of the connecting rod 31 coincides with the rotation axis of the torsion spring. The two ends of the torsion spring are respectively connected to the water filter frame 2 and the connecting rod 31, thereby pushing the connecting rod 31 to rotate toward the inner wall of the water filter frame 2 to which it is connected, so that the limiting block 32 can be stably inserted into the limiting groove 12.

[0035] To facilitate the upward rotation of the cover 1, a receiving groove 13 is provided at the upper end of the cover 1. The depth of the receiving groove 13 is less than the thickness of the cover 1, and the receiving groove 13 is connected to multiple drainage holes 11. A handle 14 is rotatably connected to the receiving groove 13. The rotation axis of the handle 14 is located near the rotation axis of the cover 1, and the handle 14 can be completely sunk into the receiving groove 13. The upper end of the limit block 32 is provided with an upwardly extending extension 34. The upper end of the extension 34 is located below the upper end surface of the cover 1, and the extension 34 and the handle 14 are close to each other. When it is necessary to rotate the cover 1 upward, the extension 34 can be pressed while grasping the handle 14. Therefore, when the handle 14 is rotated upward and an upward force is applied to the cover 1, the finger can press the extension 34 to disengage the limit block 32 from the limit groove 12, making the upward rotation process of the cover 1 more convenient.

[0036] like Figure 2 As shown, after opening the lid 1, cleaning out fallen leaves and other impurities from the water filter frame 2 is still rather troublesome. Therefore, a filter screen 4 is further provided within the water filter frame 2, covering the inner wall of the water filter frame 2. Several hooks 15 are also provided on the inner wall of the water filter frame 2. The hooks 15 are positioned below the slider 22 and the stop assembly 3, and the upper end of the filter screen 4 can be suspended from the hooks 15. Once placed within the water filter frame 2, the filter screen 4 can stably collect fallen leaves. For subsequent cleaning, the filter screen 4 can be simply removed from the water filter frame 2 to achieve cleanup.

[0037] The implementation principle of this embodiment is: when it is necessary to open the cover body 1 to clean the fallen leaves, grab the handle 14 and turn it upward, then apply an upward force to the cover body 1, press the extension 34 with your fingers while applying force, then turn the cover body 1 upward to open the cover body 1, take the filter 4 out of the water filter frame 2, clean the fallen leaves in the filter screen 4, then place the filter screen 4 in the water filter frame 2, hang the upper end opening of the filter screen 4 on the hook 15, and close the cover body 1.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
