Description

Technical Field

[0001] This invention relates to the field of sewer drainage technology, specifically to a municipal garden drainage outlet device. Background Technology

[0002] As people pay more attention to urban greening and environmental protection, more and more municipal parks are being built. However, the drainage problem of these parks is also attracting more attention. At present, most municipal parks have drainage structures, but these drainage structures can usually only simply intercept impurities such as leaves and branches.

[0003] To address the aforementioned issues, improvements have been made to existing drainage structures. Typically, filters are installed inside the drain outlet to intercept fine impurities, facilitating subsequent wastewater treatment. However, long-term use of these filters can lead to cleaning problems. Without careful inspection, it is difficult to detect filter blockages, and if clogged filters are not cleaned promptly, the drainage efficiency of the drain outlet will be significantly reduced. Summary of the Invention

[0004] The purpose of this invention is to provide a municipal garden drainage outlet device to overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A municipal garden drainage outlet device includes a drainage outlet body with a slag intercepting plate. The slag intercepting plate has an elongated slot, and a water filtering component is installed on the slot. The water filtering component includes a flexible filter screen mounted on the inner wall of the slot. When sewage falls into the slot, residue is intercepted by the flexible filter screen. A slag cleaning component is also installed within the drainage outlet body. The slag cleaning component includes multiple top plates, and a pulling component is installed on each top plate. The pulling component is responsible for actively or passively pulling the top plates upwards, causing the flexible filter screen to flip outwards, thus completing the cleaning work.

[0007] Furthermore, the pulling component includes a limiting plate located on the slag-cutting plate, and a pulling rope is fixedly connected between the limiting plate and the top plate.

[0008] Furthermore, the flexible water filter is made of an elastic material, and a buffer component is provided at the bottom of the flexible water filter.

[0009] Optionally, the pulling component further includes an outer rod and an inner rod, with an elastic element provided between the bottom of the inner rod and the inner bottom of the outer rod, and a locking component provided on the inner rod. When the locking component is not locked, the top plate is raised by the elastic element.

[0010] Furthermore, the locking component includes an arc-shaped block disposed below the inner rod, and an annular baffle is fixedly connected to the inner wall of the outer rod near the bottom. The inner rod is locked by the arc-shaped block and the annular baffle.

[0011] Furthermore, a hollow rod is fixedly connected to the bottom of the inner rod, and a telescopic member is fixedly connected to the side end of the arc-shaped block. The outer wall of the hollow rod is fixedly connected to the end of the telescopic member.

[0012] Furthermore, the top plate is provided with an unlocking component, which includes a first magnetic block. A traction member is fixedly connected to the bottom of the first magnetic block. One end of the traction member movably passes through the inner rod and the hollow rod and is fixedly connected to the arc-shaped block. When the first magnetic block rises, the inner rod is automatically unlocked by the traction member.

[0013] Furthermore, a filter plate is fixedly connected to the bottom of the flexible filter screen, and a second magnetic block is provided at the bottom of the filter plate. When the flexible filter screen extends to its maximum length, the second magnetic block approaches the first magnetic block, causing the first magnetic block to rise and unlock the inner rod.

[0014] Optionally, the top plate is hollow, and honeycomb-shaped holes are provided at the outer end of the top plate. When the top plate is located inside the long groove, sewage flows from the outside of the top plate to its interior, and finally flows into the interior of the drain outlet body.

[0015] The municipal garden drainage outlet device provided by the present invention has the following beneficial effects in the above technical solution:

[0016] By setting up a flexible water filter, fine impurities can be intercepted, and the filtration area will gradually increase with long-term use. The top plate allows for timely cleaning of the flexible water filter, ensuring it is not easily clogged. With the inner rod and elastic element, when the flexible water filter becomes severely clogged after prolonged use, gravity drives the inner rod to unlock, allowing the top plate to rise passively. This not only automatically removes impurities from the flexible water filter but also clearly alerts staff to the clogged problem, without affecting normal drainage from the drain outlet.

[0017] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0035] Example 1, please refer to Figure 1-4 A municipal garden drainage outlet device includes a drainage outlet body 1, a slag intercepting plate 2 is provided on the drainage outlet body 1, a long slot is provided on the slag intercepting plate 2, a water filtering component 3 is provided on the long slot, and the water filtering component 3 includes a flexible water filtering net 31 provided on the inner wall of the long slot. When sewage falls into the long slot, the residue is intercepted by the flexible water filtering net 31.

[0036] The top of the flexible filter screen 31 is detachably installed on the inner wall of the long slot located at the top.

[0037] The drain outlet body 1 is equipped with a slag cleaning component, which includes multiple top plates 41. The top plates 41 are located below the corresponding flexible filter screens 31. A pulling component 5 is provided on the top plates 41. The pulling component 5 is responsible for actively or passively pulling the top plates 41 upward, causing the flexible filter screens 31 to flip outward, thus completing the cleaning work.

[0038] Specifically, the drain body 1 includes a first drain pipe 11, and a pair of second drain pipes 12 are provided on both sides of the first drain pipe 11. After the sewage falls from the slag interceptor plate 2 into the first drain pipe 11, it flows to the second drain pipes 12 on both sides respectively.

[0039] To further intercept and remove sludge from the sewage, a flexible filter screen 31 is installed. The residue that falls into the long trough is collected by the flexible filter screen 31, achieving the purpose of automatic sludge removal from the sewage. A top plate 41 is installed, which is adapted to the long trough. The top plate 41 is driven to rise, causing the flexible filter screen 31 to flip outward, thereby completing the cleaning work of the flexible filter screen 31.

[0040] In a further embodiment of the present invention, the pulling component 5 includes a limiting plate 51 located on the slag-cutting plate 2, and a pulling rope 52 is fixedly connected between the limiting plate 51 and the top plate 41.

[0041] When municipal staff conduct inspections at regular intervals, they can pull the limit plate 51 and use the pull rope 52 to pull the top plate 41 up, causing the top plate 41 to lift the flexible filter screen 31, thereby completing the cleaning work.

[0042] Optionally, multiple top plates 41 can be fixedly connected by connecting plates, so that pulling a limiting plate 51 can complete the raising of all top plates 41.

[0043] The flexible water filter 31 is made of elastic material. A buffer component is provided at the bottom of the flexible water filter 31 to ensure that the speed of the flexible water filter 31 is slowed down when it rebounds.

[0044] Specifically, the flexible water filter net 31 consists of two sets of lines, warp and weft. The warp lines are made of elastic material, while the weft lines are made of ordinary non-elastic material. Therefore, when the flexible water filter net 31 is subjected to gravity due to the accumulation of sewage inside, it will extend downwards instead of extending to the left or right.

[0045] The buffer component is a sliding rod. A guide bar 8 is fixedly connected to the inner wall of the drain outlet body 1. The end of the sliding rod 9 slides on the outer wall of the guide bar 8. The bottom of the flexible filter screen 31 is fixedly connected to the sliding rod 9. The speed of rebound is reduced by the sliding between the sliding rod 9 and the guide bar 8.

[0046] A roller may also be provided on the side end of the slide bar 9, so that the roller rolls on the outer wall of the guide bar.

[0047] Example 2 differs from Example 1 in that the following technical features are added: Please refer to... Figure 5-11 The bottom of the top plate 41 is provided with a driving component, which includes an outer rod 53 and an inner rod 54 (made of lightweight material). The bottom of the top plate 41 is fixedly connected to the top of the inner rod 54. An elastic element 55 is provided between the bottom of the inner rod 54 and the inner top of the outer rod 53. A locking component 6 is provided on the inner rod 54. When the locking component 6 is not locked, the top plate 41 is raised by the elastic element 55.

[0048] The bottom of the outer rod 53 is fixedly connected to the inner bottom surface of the drain outlet body 1. The inner rod 54 slides on the inner wall of the outer rod 53. The elastic element 55 is a strong elastic rope with an elastic force between 10 and 30 Newtons.

[0049] A sealing ring is provided between the outer rod 53 and the inner rod 54.

[0050] The locking component 6 includes an arc-shaped block 61 disposed below the inner rod 54, and an annular baffle 62 is fixedly connected to the inner wall of the outer rod 53 near the bottom. Since the arc-shaped block 61 is limited by the annular baffle 62, the inner rod 54 is locked.

[0051] A hollow rod 63 is fixedly connected to the bottom of the inner rod 54, and a telescopic member 64 is fixedly connected to the side end of the arc-shaped block 61. The outer wall of the hollow rod 63 is fixedly connected to the end of the telescopic member 64.

[0052] Specifically, the telescopic component 64 includes a fixed column and a movable column. A return spring is sleeved on the outside of the movable column. The movable column is fixedly connected to the arc-shaped block 61, and the fixed column is fixedly connected to the outer wall of the hollow rod 63.

[0053] The top plate 41 is provided with an unlocking component 7, which includes a first magnetic block 71. A traction component 72 is fixedly connected to the bottom of the first magnetic block 71. One end of the traction component 72 movably passes through the inner rod 54 and the hollow rod 63, and is fixedly connected to the arc-shaped block 61. When the first magnetic block 71 rises, the inner rod 54 is automatically unlocked by the traction component 72.

[0054] The bottom of the flexible water filter 31 is fixedly connected to a water filter plate 73. A second magnetic block 74 is provided at the bottom of the water filter plate 73. When the flexible water filter 31 extends to its maximum length, the second magnetic block 74 approaches the first magnetic block 71, causing the first magnetic block 71 to rise and unlock the inner rod 54.

[0055] One end of the traction component 72 is connected to the first magnetic block 71, and the other end is fixedly connected to the outer wall of the movable column. The inner rod 54, the hollow rod 63 and the fixed column are all provided with rope holes. The rope hole on the hollow rod 63 is L-shaped, and a pulley is provided at the corner to reduce friction with the traction component 72.

[0056] When the flexible filter screen 31 extends to its maximum length, it will be difficult to extend further. At this point, the force that continues to deform and extend is much greater than the elastic force of the return spring, causing the telescopic component 64 to contract and the arc-shaped block 61 to move.

[0057] Initially, under the constraint of the annular baffle 62, the arc-shaped block 61 forces the inner rod 54 to retract inside the outer rod 53. At this time, the top plate 41 is located below the flexible filter screen 31. When the flexible filter screen 31 begins to collect residue, its permeability decreases, and more and more water accumulates inside, causing it to experience increasing pressure. Finally, when the flexible filter screen 31 extends to its maximum length, the second magnetic block 74 approaches the first magnetic block 71, causing the first magnetic block 71 to move upward under magnetic force. Through the traction member 72, the arc-shaped block 61 is pulled to move, causing the telescopic member 64 to retract. After the arc-shaped block 61 disengages from the annular baffle 62, under the action of the elastic member 55, the inner rod 54 moves upward, eventually pushing the flexible filter screen 31 up with the top plate 41, causing it to flip outward, thus achieving the purpose of automatic cleaning.

[0058] When heavy rain occurs, the top plate rises passively. When the top plate 41 is located on the inner wall of the long groove, the impurities on the flexible filter screen 31 are washed away by the impact of rainwater, effectively preventing the long groove from being blocked.

[0059] Please see Figure 12 The top plate 41 is hollow, and honeycomb-shaped holes are provided at the outer end of the top plate 41. The cross-sectional area of ​​the holes is larger than the cross-sectional area of ​​the mesh of the flexible filter screen 31. When the top plate 41 is located inside the long groove, sewage flows from the outside of the top plate 41 to its interior, and finally flows into the interior of the drain outlet body 1.

[0060] In a further embodiment of the present invention, when the top plate 41 enters the long slot, external sewage can still enter the drain body 1 through the top plate 41 to achieve normal sewage discharge. Subsequently, the staff presses the top plate 41, causing the arc-shaped block 61 to automatically retract and enter below the annular baffle 62 to lock the inner rod 54.

[0061] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
