Description

Technical Field

[0001] This utility model relates to the field of rainwater treatment technology, specifically a rainwater collection device for green service areas along highways. Background Technology

[0002] The main function of highway service areas is to facilitate refueling for passing vehicles and rest for pedestrians. Service areas are the largest among the ancillary facilities, and they also have the largest traffic and pedestrian flow. This leads to a problem of high water consumption and a large amount of water waste in service areas. Therefore, it is necessary to take measures to reduce the amount of fresh water used in service areas and increase the amount of recycled water. The available water resources in service areas mainly include domestic sewage and natural rainfall. Rainwater is usually discharged directly outside the service area through the rainwater pipe network, resulting in a low recycling rate of available water resources in service areas.

[0003] To improve the utilization rate of rainwater, rainwater is usually collected. However, service areas inevitably have some trees planted, and small branches and leaves will fall into the sewers. Therefore, it is essential to install a device to filter branches and leaves. Moreover, leaves that get wet can easily stick to the filter device and cause blockage. It is also particularly important to handle the filtered branches and leaves.

[0004] Therefore, this utility model provides a rainwater collection device for green service areas on highways to solve the above problems. Utility Model Content

A connecting platform is fixedly connected to each of the two sliders, and a mounting platform is fixedly connected to the push plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a rainwater harvesting device for green service areas along highways, such as... Figures 1-6 As shown, the technical solution includes a sewer 1, a treatment tank 2, and a collection tank 3. The collection tank 3 is equipped with a pumping pipe 11 and a water pump 12. The water collected in the collection tank 3 is pumped out by the water pump 12 and the pumping pipe 11 for reuse. A filter screen 8 is installed between the treatment tank 2 and the collection tank 3 to filter branches and leaves. A guide plate 6 is fixedly connected inside the treatment tank 2, and a connecting plate 7 is fixedly connected to the bottom of the guide plate 6. A baffle mechanism is provided between the connecting plate 7 and the filter screen 8. The baffle mechanism includes a partition plate 14 and two springs 17. The box 2 is symmetrically fixed with mounting plates 19. A pushing mechanism is provided between the two mounting plates 19. The pushing mechanism includes a bidirectional lead screw 21, a push plate 26 and multiple cross components. The cross components include two cross-arranged connecting rods 24. When too many branches and leaves accumulate, the partition plate 14 in the drive partition mechanism retracts into the cavity, and some branches and leaves fall into the collection box 5. Then, the push plate 26 in the drive mechanism moves down, and the remaining branches and leaves are pushed into the collection box 5 by the push plate 26. This achieves the effect of filtering and processing branches and leaves, making it more practical.

[0026] A cavity is provided inside the connecting plate 7, and the partition plate 14 is slidably connected in the cavity. Round rods 16 are symmetrically fixed in the cavity and slide through the partition plate 14. Two springs 17 are respectively sleeved on the two round rods 16. An electromagnet 18 and an iron plate 15 are provided in the cavity. The iron plate 15 is fixedly connected to the partition plate 14. A collection box 5 is provided below the partition plate 14 and is movably connected to the processing box 2.

[0027] When too many branches and leaves accumulate on the guide plate 6, the electromagnet 18 is energized, causing it to attract the iron plate 15. During this process, the iron plate 15 drives the partition 14 to compress the spring 17 and retract into the cavity. Some of the branches and leaves accumulated on the guide plate 6 fall into the collection box 5. When the branches and leaves on the guide plate 6 are processed, the electromagnet 18 is de-energized, and the compressed spring 17 returns to its original position, pushing the partition 14 out of the cavity so that rainwater can continue to be filtered.

[0028] It should be noted that electromagnet 18 is a device that generates electromagnetism when energized. A conductive winding matching its power is wound around the outside of the iron core. This coil carrying current has magnetism like a magnet. Electromagnet 18 is existing technology and will not be elaborated on here.

[0029] Inside the treatment box 2, guide plates 13 are symmetrically fixed. The two ends of the push plate 26 are slidably connected to the two guide plates 13 respectively. The bidirectional screw 21 is rotatably connected between the two mounting plates 19. The pushing mechanism also includes two sliders 22, which are slidably connected between the two mounting plates 19. Both sliders 22 are threadedly connected to the bidirectional screw 21. A connecting platform 23 is fixedly connected to each slider 22. A mounting platform 25 is fixedly connected to the push plate 26. Multiple cross components are rotatably connected between the mounting platform 25 and the connecting platform 23. A motor 20 is fixedly connected to the side wall of the mounting plate 19. The output end of the motor 20 is coaxially fixed to the bidirectional screw 21. Two positioning rods 9 are rotatably connected to the treatment box 2. Two positioning blocks 10 are fixedly connected to the water collection tank 3. A cover plate 4 is bolted to the top of the water collection tank 3. By opening the cover plate 4 and rotating the positioning rods 9, the filter screen 8 can be pulled out for easy cleaning and replacement.

[0030] When in use, the start motor 20 drives the bidirectional lead screw 21 to rotate. The rotating bidirectional lead screw 21 drives the two sliders 22 to move in opposite directions. The moving sliders 22 drive the connecting rod 24 to rotate. When the two sliders 22 are close to each other, the connecting rod 24 pushes the push plate 26 down, and the push plate 26 pushes the remaining branches and leaves into the collection box 5 to prevent the branches and leaves from clogging the filter screen 8. When the two sliders 22 are far apart, the connecting rod 24 drives the push plate 26 up to prevent the connecting rod 24 and the push plate 26 from obstructing the filtration of rainwater.

[0031] It should be noted that the motor 20 is connected to an external power source via wires. The external power source includes a battery for providing power to the motor 20 and a control switch for controlling its start and stop. The external power source is existing technology. The specific model and specifications of the motor 20 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described in detail.

[0032] In summary: During operation, when electromagnet 18 is energized, it attracts iron sheet 15. During this process, iron sheet 15 drives partition 14 to compress spring 17 and retract into the cavity. Some of the branches and leaves accumulated on guide plate 6 fall into collection box 5. At the same time, motor 20 is started to drive bidirectional lead screw 21 to rotate. The rotating bidirectional lead screw 21 drives two sliders 22 to move in opposite directions. The moving sliders 22 drive connecting rod 24 to rotate. Through connecting rod 24, pusher plate 26 moves down. Pusher plate 26 pushes the remaining branches and leaves into collection box 5 to prevent branches and leaves from clogging filter screen 8.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
