Description

Technical Field

[0001] This application relates to the technical field of irrigation for the green belts of municipal roads. More specifically, it relates to an irrigation device for sunken green belts under municipal roads. Background Art

[0002] A sunken green space refers to a public green space with an elevation lower than the surrounding road surface, also known as a low-lying green space. Contrary to a "flower bed", its concept is to use open space to receive and store rainwater, achieving the effect of reducing runoff discharge. Generally speaking, there are certain requirements for the sunken depth of low-lying green spaces, and their soil quality is mostly unimproved. Compared with the "linear" vegetation shallow ditch, it is mainly a "surface" that can receive more rainwater, and the plants inside are mostly native herbs.

[0003] The sunken green belt fully considers rainwater utilization. The irrigation device is placed at the bottom of the sunken area, collecting and storing rainwater during the rainy season or when rainwater is sufficient. During the dry season or when rainwater is insufficient, the collected rainwater can be used for irrigation and plant maintenance in the green belt.

[0004] However, during the process of rainwater recycling by the current irrigation device, a large amount of silt will accumulate in the water storage well. After a large amount of silt settles, it will cause a reduction in the water storage capacity of the water storage well. If the rainwater and silt cannot be separated in time, the silt may contain pollutants such as heavy metals and organic substances, and the accumulation of these pollutants in the water storage well will cause poisoning to the plants in the green belt.

[0005] In view of this, we propose an irrigation device for sunken green belts under municipal roads. Summary of the Invention

[0033] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0034] A watering device for a sunken green belt under a municipal road, comprising: a rainwater sedimentation tank 1, the rainwater sedimentation tank 1 including a water accumulation hopper 11, a mesh plate 12 and a sedimentation tank 13, the water accumulation hopper 11 being an inverted trapezoidal structure, the mesh plate 12 being fixed to the large-diameter end of the upper end of the water accumulation hopper 11, and the small-diameter end of the water accumulation hopper 11 being connected to the sedimentation tank 13 in a through manner; a silt cleaning assembly 2, rotatably arranged in the sedimentation tank 13; a silt collection well 3, connected to one side of the bottom of the sedimentation tank 13 in a through manner, and the sedimentation tank 13 and the silt collection well 3 being openable and closable; a water storage well 4, connected to one side of the upper end of the sedimentation tank 13 in a through manner; and an irrigation mechanism 5, connected to the water storage well 4 in a through manner.

[0035] Refer to Figure 1 - Figure 7 , manhole covers 6 are provided at the tops of both the silt collection well 3 and the water storage well 4 to prevent soil from falling into the wells. The whole is buried in the sunken part of the sunken green belt. During rainy weather, rainwater is filtered through the mesh plate 12 and collected through the water accumulation hopper 11. When the sedimentation tank 13 and the silt collection well 3 are in a closed state, the sedimentation tank 13 is used for rainwater sedimentation. The sedimented silt remains in the sedimentation tank 13, and the rainwater overflows into the water storage well 4 after sedimentation. Then, during the dry season when water is lacking, the rainwater in the water storage well 4 is pumped out through the irrigation mechanism 5 to spray and irrigate the green belt. And the sedimentation tank 13 and the silt collection well 3 are opened, and then the silt in the sedimentation tank 13 is cleaned into the silt collection well 3 through the silt cleaning assembly 2 to facilitate the separation of the silt from the rainwater, and at the same time, the silt collection well 3 facilitates the centralized cleaning of the silt.

[0036] The rainwater sedimentation tank 1 further includes a silt discharge pipe 15, an overflow pipe 14, a sluice gate 16 and a servo electric cylinder 17. A silt discharge port 131 is opened on one side of the bottom of the sedimentation tank 13. The silt discharge pipe 15 corresponds to the silt discharge port 131 and is fixed on the sedimentation tank 13. The overflow pipe 14 is connected through and between the sedimentation tank 13 and the water storage well 4. The sluice gate 16 is vertically inserted and slid on the silt discharge pipe 15. The sluice gate 16 is attached to the side of the silt discharge port 131 of the sedimentation tank 13. The size of the sluice gate 16 is larger than that of the silt discharge port 131. The servo electric cylinder 17 is vertically fixed on the sedimentation tank 13, and the piston rod of the servo electric cylinder 17 is fixed to the sluice gate 16.

[0037] Refer to Figure 2 - Figure 4 , the silt discharge port 131 is opened at the lower left end of the sedimentation tank 13, and the overflow pipe 14 is connected through and at the upper right end of the sedimentation tank 13 for the overflow of the sedimented rainwater into the water storage well 4. And the lifting of the sluice gate 16 is driven by the piston rod of the servo electric cylinder 17. When the sluice gate 16 blocks the silt discharge port 131, the sedimentation tank 13 and the silt collection well 3 can be closed. At this time, the sedimentation tank 13 is used for the sedimentation of rainwater. At the same time, when the piston rod of the servo electric cylinder 17 contracts, the sluice gate 16 rises upward, and the silt discharge port 131 is communicated with the silt discharge pipe 15. At this time, the sedimentation tank 13 is communicated with the silt collection well 3 to facilitate the cleaning of the silt.

[0038] The silt cleaning component 2 includes a servo motor 21 and a auger 22. The bottom of the sedimentation tank 13 is of an arc structure. The auger 22 is adapted to the arc surface of the sedimentation tank 13. The servo motor 21 is fixed on the sedimentation tank 13, and the servo motor 21 is in transmission connection with the auger 22. The auger 22 is rotatably arranged in the sedimentation tank 13.

[0039] Refer to Figure 3 , both ends of the auger 22 are rotatably arranged on the sedimentation tank 13 through bearings, and the output shaft of the servo motor 21 is coaxially fixed to the shaft rod of the auger 22. And when the auger 22 rotates counterclockwise, the auger 22 discharges the silt in the sedimentation tank 13 from right to left through the silt discharge port 131, and thus the cleaning of the silt in the sedimentation tank 13 can be completed.

[0040] A silt collection bucket 31 is arranged in the silt collection well 3. A towing rope 32 is fixed at the open end of the silt collection bucket 31. The silt collection bucket 31 is placed below the silt discharge pipe 15.

[0041] Refer to Figure 3 and Figure 6 , the silt collection bucket 31 is placed into the silt collection well 3, and the opening of the silt collection bucket 31 is placed below the silt discharge pipe 15. The silt discharged from the silt discharge pipe 15 falls into the silt collection bucket 31, and through the towing rope 32, it is convenient to lift the silt collection bucket 31 out of the silt collection well 3, and then the silt in the bucket can be centrally cleaned.

[0042] The irrigation mechanism 5 includes a submersible pump 51 immersed in the water storage well 4, a main water pipe 52 connected in a through manner to the outlet pipe of the submersible pump 51, a plurality of shunt pipes 53 connected in a through manner to the main water pipe 52, and a plurality of spray heads 54 connected in a through manner to the shunt pipes 53. The main water pipe 52 is provided with a valve 521.

[0043] Refer to Figure 1 and Figure 4 and Figure 7 , after the valve 521 is opened and the submersible pump 51 is powered on, the submersible pump 51 pumps the rainwater in the water storage well 4 after being powered on, then it is shunted through the main water pipe 52 into a plurality of shunt pipes 53, and finally the green belt is sprinkled and irrigated through the spray heads 54.

[0044] A circular ring 41 is fixed inside the water storage well 4. A debris collection barrel 42 is arranged inside the water storage well 4. A plurality of water drainage holes 421 are formed at the bottom of the debris collection barrel 42. The debris collection barrel 42 is fixed with a towing rod 43.

[0045] Refer to Figure 3 - Figure 5 , the main water pipe 52 passes through the water storage well 4, and the circular ring 41 is placed at the upper end of the part of the submersible pump 51 and the main water pipe 52 placed in the water storage well 4. The debris collection barrel 42 is placed into the water storage well 4 and placed on the circular ring 41. The rainwater overflowed from the overflow pipe 14 is intercepted by the debris again through the water drainage holes 421 to reduce the blockage of the submersible pump 51 caused by debris falling into the water storage well 4. At the same time, the debris collection barrel 42 can be lifted out of the water storage well 4 through the towing rod 43, and then the garbage in the debris collection barrel 42 can be cleaned.

[0046] Both the servo motor 21 and the servo electric cylinder 17 are sleeved inside the protective cover 7, and the protective cover 7 is fixed on the sedimentation tank 13.

[0047] Refer to Figure 2 , both the servo motor 21 and the servo electric cylinder 17 are sleeved inside the protective cover 7 to protect the servo motor 21 and the servo electric cylinder 17 through the protective cover 7.

[0048] Working principle: It is integrally buried in the depression of the sunken green belt, and a gravel layer, a sand layer and a planting soil layer are sequentially laid above the mesh plate 12. The planting soil layer is used for planting green plants, and the sand layer and the gravel layer are used for rainwater filtration. The sprinkler head 54 protrudes from the planting soil layer. After the rainwater is filtered by the sand layer and the gravel layer, it is intercepted and filtered by the mesh plate 12, flows into the water collecting hopper 11, and then is collected in the sedimentation tank 13 for sedimentation. After the sedimentation of the rainwater, when the liquid level reaches the overflow pipe 14, the rainwater overflows through the overflow pipe 14 into the water storage well 4, and is intercepted and filtered again through the water drainage holes 421 of the impurity collection barrel 42. After being filtered multiple times, the rainwater is stored in the water storage well 4. When it is necessary to dredge the sedimentation tank 13, the servo electric cylinder 17 is energized at this time and the piston rod contracts. The piston rod pulls the gate plate 16 upward, the sludge discharge port 131 is communicated with the sludge discharge pipe 15, and the servo motor 21 is started to drive the auger 22 to rotate counterclockwise. The auger 22 pushes the sludge in the sedimentation tank 13 towards the sludge discharge pipe 15 and drops into the sludge collection barrel 31 in the sludge collection well 3. When it is necessary to irrigate the green belt, the valve 521 and the submersible pump 51 are opened. After the submersible pump 51 is energized, it pumps the rainwater in the water storage well 4, and then is shunted into multiple shunt pipes 53 through the main water pipe 52. Finally, the green belt is sprinkled and irrigated through the sprinkler head 54.
