Description

Technical Field

[0001] This utility model belongs to the technical field of filtration and interception devices, specifically relating to a device for intercepting pollutants from surface runoff in gardens. Background Technology

[0002] In road drainage systems, rainwater runoff often carries a large amount of pollutants, including vegetation, leaves, packaging bags, plastic products, and other solid waste. These pollutants, once carried by the water flow into the drainage network, can easily cause blockages, severely impacting the normal operation of the urban drainage system. To address this problem, existing technologies typically involve installing interceptor grilles at runoff collection points to filter solid waste from the runoff through physical barriers.

[0003] However, this traditional interception device has significant drawbacks: as the intercepted garbage accumulates, the effective water-passing area of the grid gradually decreases, leading to a continuous decline in drainage capacity. Especially under heavy rainfall conditions, the water level in front of the grid can rise rapidly due to poor drainage, causing not only severe water accumulation on the road surface but also potential damage to the grid structure due to increased water pressure. More seriously, when the water depth exceeds the height of the curb, the intercepted garbage may re-enter the environment with the overflowing water, causing secondary pollution.

[0021] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below to facilitate understanding by those skilled in the art.

[0022] Please see Figures 1 to 6 This embodiment provides a garden surface runoff pollutant interception device, which is installed at the node of road 1 where water flows. It includes: an interception grid 2 installed on the road 1 and having two working states: horizontal and vertical. When it rains, the interception grid 2 vertically intercepts garbage, and when it does not rain, it is horizontal to facilitate passage.

[0023] Multiple horizontal grid plates 3 are installed on the water-facing side of the intercepting grid plate 2 and are closely attached to the vertically positioned intercepting grid plate 2; driving devices are installed on both sides of the road 1 to drive the horizontal grid plates 3 to rise one by one; when garbage accumulation causes the water level to rise, the driving devices can sequentially raise the horizontal grid plates 3, thus maintaining effective interception of garbage while ensuring sufficient drainage capacity.

[0024] The road 1 is provided with a first groove 4 to accommodate all of the horizontal grid plates 3; the road 1 is provided with a second groove 5 to accommodate the intercepting grid plates 2 in a flat position. When not in operation, the intercepting device merges with the road surface and does not obstruct traffic.

[0025] A vertical plate 6 is provided on the side of the horizontal grid plate 3 away from the interception grid plate 2; when the horizontal grid plate 3 is raised, the vertical plate 6 prevents garbage from falling off the horizontal grid plate 3.

[0026] The horizontal grid plate 3 has four support columns 7 of equal height at its bottom corners; the function of the support columns 7 is to provide a certain distance between the horizontal grid plates 3 when the horizontal grid plate 3 is located in the first groove 4, so as to facilitate the gripping of the driving device.

[0027] The horizontal grid plate 3 is provided with horizontal support plates 8 on both sides.

[0028] The driving device includes: guide grooves 9 fixed to the road 1 on both sides of the first groove 4; an n-shaped support frame 10 above the guide grooves 9; a sliding rod 11 inside the guide grooves 9 and extending upward through the n-shaped support frame 10; anti-fall mechanisms 28 on both sides of the n-shaped support frame 10 and in number corresponding to the horizontal grid plates 3; a horizontal grid plate lifting mechanism at the top of the n-shaped support frame 10; and guide holes on the horizontal support plate 8 that slide with the sliding rod 11.

[0029] The anti-fall mechanism 28 includes: first square holes 12 symmetrically arranged on both sides of the n-shaped support frame 10 at equal intervals; a first fixed seat 13 located outside the first square holes 12; an anti-fall lock pin 14 slidably disposed within the first fixed seat 13 and directly opposite the first square holes 12; a lock pin limiting piece 15 disposed on the anti-fall lock pin 14 and larger in size than the first square holes 12; a first wedge-shaped lock tongue 16 located at the front end of the lock pin limiting piece 15; a first return spring 17 sleeved on the anti-fall lock pin 14 and located between the lock pin limiting piece 15 and the first fixed seat 13; and the front end of the first wedge-shaped lock tongue 16 is provided with a downwardly sloping guide surface. When the horizontal grid plate 3 rises, the guide slope contacts the horizontal support plate 8 of the horizontal grid plate 3 and retracts, allowing the horizontal grid plate 3 to rise smoothly. After the horizontal grid plate 3 rises, the first return spring 17 resets the first wedge-shaped locking tongue 16, preventing the horizontal grid plate 3 from falling. The tail of the anti-fall lock pin 14 is provided with a first pull ring, which is used to pull a wedge-shaped locking tongue to manually lower the horizontal grid plate 3.

[0030] The horizontal grid plate lifting mechanism includes: an electric push rod 18 fixed to the top of the n-shaped support frame 10; a piston rod 19 of the electric push rod 18 passing vertically downward through the top of the n-shaped support frame 10; and a locking mechanism 29 for engaging the horizontal support plate 8 at the lower end of the piston rod 19. The locking mechanism 29 includes: a locking mounting plate 20 fixed to the lower end of the piston rod 19; a second square hole 21 disposed on the locking mounting plate 20; a second fixing seat 22 disposed outside the second square hole 21; a locking latch pin 23 slidably disposed in the second fixing seat 22 and facing the second square hole 21; a locking latch pin limiting piece 24 disposed on the locking latch pin 23 and larger in size than the second square hole 21; a second wedge-shaped locking tongue 25 disposed at the front end of the locking latch pin limiting piece 24; a second return spring 26 sleeved on the locking latch pin 23 and located between the locking latch pin limiting piece 24 and the second fixing seat 22; and a downwardly sloping guide surface at the front end of the second wedge-shaped locking tongue 25. The piston rod 19 of the electric push rod 18 descends, contacting and retracting the horizontal support plate 8 with its guide ramp facing downwards, allowing the piston rod 19 to descend smoothly. The second return spring 26 resets the second wedge-shaped locking tongue 25, and the second wedge-shaped locking tongues 25 on both sides lock the horizontal grid plates 3 on both sides, allowing the piston rod 19 to smoothly drive the plates upwards. The tail of the latch pin 23 is provided with a second pull ring to allow the horizontal grid plate 3 to be manually reset.

[0031] In this embodiment, the electric actuator 18 is synchronously controlled by the same controller. The electric actuator 18 is a LINAK LA36 series stroke-controlled electric actuator, and the controller is an STM32 series microcontroller. The servo motor 27 is also controlled by the same microcontroller. The preset downward and upward strokes of the horizontal grid plate 3 are determined from top to bottom, and are operated manually in actual use.

[0032] The interceptor gate 2 has a rotating shaft on the side near the horizontal gate 3; mounting seats for servo motors 27 are pre-embedded on both sides of the road 1; the output shaft of the servo motor 27 is connected to the rotating shaft for transmission. The servo motor 27 is a synchronous servo motor used to drive the interceptor gate 2 to achieve both horizontal and vertical states.

[0033] Both the servo motor 27 and the electric actuator 18 have an IP67 protection rating.

[0034] In this embodiment, a water level gauge is used to measure the water level.

[0035] When using the garden surface runoff pollutant interception device of this utility model:

[0036] (1) Initial state: The intercepting grid plate 2 is placed flat in the second groove 5, and the horizontal grid plate 3 is stored in the first groove 4, flush with the road surface.

[0037] (2) Interception state: When it rains, the servo motor 27 drives the interception grid 2 to stand up to 90°. When the intercepted garbage causes the water level to rise, the first horizontal grid 3 is raised to the highest position of the anti-fall mechanism 28 under the action of the electric push rod 18. When the water level rises again, the second horizontal grid 3 is raised to the second highest position of the anti-fall mechanism 28 under the action of the electric push rod 18. And so on.

[0038] (3) Reset process: After the rain ends, clean up the garbage and manually reset the horizontal grid plate 3 to the first groove 4. The servo motor 27 will flatten the interception grid plate 2 and reset it to the second groove 5.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
