Description

Technical Field

[0001] The utility model relates to the field of river water intake sprinkler irrigation equipment, in particular to a river bank green belt sprinkler irrigation device. Background Art

[0002] In the design process of most artificial canals, moats, landscape rivers and other rivers, in order to improve the river bank protection effect and enhance the landscape effect, it is considered to set up green belts on both sides of the river. In order to maintain the normal growth of plants in the riverside green belt, it is considered to design sprinkler devices for regular watering and maintenance. Conventional sprinkler devices for riverside green belts usually set up irrigation nozzles in the green belts, and then connect the water inlet end of the nozzles to the municipal water pipe network, and control the nozzles to open at a time to achieve timed irrigation. This method has the defect of wasting municipal water.

[0003] CN201920402147.1 has disclosed a drainage irrigation system for river slope protection green belts, including a water storage device arranged on one side of the slope top, a planting trough arranged on the slope body, and a connecting pipe for horizontally connecting two adjacent planting troughs; the planting troughs are arranged in the planting area of ​​the slope body and are arranged in rows horizontally; the planting troughs include a trough body, a water flow plate laterally connected to one side of the rear wall of the trough body, water inlet and outlet holes arranged on the upper parts of the left and right side walls of the trough body, and a water outlet arranged on the upper part of the front wall of the trough body, and the water flow plates of the planting troughs in the next row are abutted against the trough bodies of the planting troughs in the previous row; the water inlet and outlet holes at both ends of each row are closed; the runoff rainwater on the top surface of the slope is collected by the water storage device, and the slope protection plants are irrigated to reduce the water used for greening; the irrigation method of using water to discharge step by step from top to bottom is used to evenly fill all the planting troughs with water, so that the plants in each planting trough can be watered separately and fully.

[0004] CN202310408893.2 disclosed a waterfront sidewalk for controlling rainwater runoff pollution, wherein green belts are provided on both sides of the sidewalk, and a river channel and a motor vehicle lane are provided on both sides of the two green belts respectively. The sidewalk is paved with permeable pavement, and a linear drainage ditch and impermeable concrete are provided at the bottom of the permeable pavement. Compared with conventional waterfront sidewalks, this invention can achieve on-site control of rainwater runoff pollution, thereby reducing pollutants entering the river, improving the water quality of the river, and at the same time reusing rainwater to irrigate green spaces and save water resources.

[0005] The above two existing patent technologies both adopt the method of collecting rainwater for watering green belts, but this method relies on the collection of rainwater and has poor stability.

[0006] CN201621446254.7 also disclosed an electricity-free irrigation system for the green belt on the bank of an urban river, in which a cover body is buckled in a pit, a water outlet is formed on the right side of the cover body, a water inlet pipe is filled in the dam, the water inlet pipe is connected to the cover body, an air inlet pipe is connected to the water inlet pipe, and the diameter of the air inlet pipe is 0.5 to 1 cm; an air collecting box is fixed on the cover body, a water pressure pipe is fixed on the cover body, the lower end of the water pressure pipe extends into the lower part of the cover body, and the upper end extends into the air collecting box; the upper end of the air collecting pipe is connected to the upper part of the air collecting box, the lower end is connected to the cover body, and the lower end is located at the upper part of the cover body; one end of the air outlet pipe is connected to the air collecting box, and the other end is connected to the lower end of the water outlet pipe, the water outlet pipe is fixed on the cover body, and the lower end of the water outlet pipe extends into the water in the river channel on the right side, and the water outlet pipe on the right side of the dam is connected to the watering pipe of the river bank green belt. This solution can realize automatic irrigation of the green belts along the river bank without electricity by using the water flowing in the river. However, this solution requires building a dam first and diverting water to a lower place to introduce bubbles, and then collecting the bubbles to generate air pressure to press the water to a higher place. Its structure is complex, the requirements for the on-site environment are high, the hydraulic efficiency is low, and the practicality of the solution is poor.

[0007] Therefore, how to design a river bank green belt sprinkler irrigation equipment that can directly utilize river water and hydraulic power to irrigate the river bank green belt and has better practicality has become a problem that technical personnel in this field need to consider and solve. Utility Model Content

[0008] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the utility model is: how to provide a riverbank green belt sprinkler irrigation device which can directly utilize river water and hydraulic power for irrigation and is more energy-saving, environmentally friendly and practical.

[0009] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0010] A riverbank green belt sprinkler irrigation device comprises a nozzle arranged in the riverbank green belt and a water-drawing device arranged in a river channel, and is characterized in that the water-drawing device comprises a mounting frame relatively fixedly arranged above the water surface of the river channel, a water-drawing box is arranged on the mounting frame, a piston which can slide along the length direction of the water-drawing box is arranged in the width direction of the water-drawing box, a pull rod extending out of the water-drawing box is vertically arranged at one end of the piston, the outer end of the pull rod is connected to the rotating shaft of an impeller through a reciprocating transmission mechanism, the impeller is arranged in the direction of the river flow and the lower part is immersed under the water surface of the river channel, a water inlet and a water outlet are provided at the inner end of the water-drawing box away from the piston, a water inlet check valve is arranged at the water inlet and connected to the water inlet pipe, the outer end of the water inlet pipe extends downward to below the water surface of the river channel, a water outlet check valve is arranged at the water outlet and connected to the water outlet pipe, and the outer end of the water outlet pipe is connected to the nozzle.

[0011] In this way, when the device is used, the river water flow impels the impeller to rotate, and the reciprocating transmission mechanism can drive the piston to reciprocate. When the piston moves outward, the water inlet check valve opens and the water outlet check valve closes, so that the river water is drawn from the water inlet pipe into the water pumping box. When the piston moves inward, the water inlet check valve closes and the water outlet check valve opens, so that the river water is pressed out of the water pumping box and finally flows out from the nozzle to irrigate the green belt. Therefore, the device can directly use the river water source and hydraulic power to achieve irrigation, which is energy-saving and environmentally friendly. Compared with the background technology, it uses the water flow to directly drive the impeller to rotate to generate power to pump water, which is more reliable, stable and more practical.

[0012] Furthermore, the water pumping box is horizontally arranged along the direction of water flow, and the reciprocating transmission mechanism includes a sliding sleeve vertically fixed to the outer end of the pull rod, and also includes a slider that can be slid up and down in the sliding sleeve. The slider is installed and fixed at an external position on the side of a turntable. The turntable is relatively installed above the impeller and the turntable shaft is connected to the rotating shaft of the impeller through a transmission belt.

[0013] In this way, the impeller is driven by the water flow to rotate, driving the turntable to rotate, and then driving the piston to reciprocate through the cooperation of the slider and the sleeve. It has the advantages of simple structure, reliability and stability.

[0014] Furthermore, the mounting frame is fixed on a float, and the float floats on the water surface of the river.

[0015] In this way, the float can rise and fall with the rise and fall of the river water level, ultimately making the operation of the device unaffected by the water level.

[0016] Furthermore, a horizontal limiting structure is provided for limiting the float in the horizontal direction.

[0017] In this way, the operation of the device can be better ensured to be stable and reliable.

[0018] Furthermore, the horizontal limiting structure includes a foundation pile vertically fixedly arranged in the river channel, the cross section of the foundation pile is non-circular, a vertical sliding hole is arranged in the middle of the float corresponding to the foundation pile and the float can be slidably installed on the foundation pile.

[0019] This has a simple structure and reliable limiting function.

[0020] Furthermore, a roller is provided on the inner surface of the vertical sliding hole in the middle of the float.

[0021] In this way, the rolling friction between the roller and the pile makes it easier for the float to slide up and down.

[0022] Furthermore, a water reservoir is provided at the upper end of the river bank green belt, the outer end of the outlet pipe is upwardly connected to the upper port of the water reservoir, a sprinkler pipe connected to a sprinkler head is provided at the bottom of the water reservoir, and a control valve is installed on the sprinkler pipe.

[0023] In this way, when watering is needed, the control valve can be opened to open the sprinkler for watering.

[0024] Furthermore, a humidity sensor is provided in the river bank green belt, and the humidity sensor is connected to the control valve.

[0025] This can automatically detect the humidity in the riverside green belt and determine whether watering is needed. When watering is needed, the sprinkler head can be controlled to open to avoid excessive waterlogging in the green belt and affect plant growth.

[0026] Furthermore, an overflow port is provided at the upper end of the reservoir, and an overflow channel is provided outside the overflow port to connect with the river channel.

[0027] In this way, excess water can flow back into the river along the overflow port and the overflow channel instead of overflowing the reservoir and causing flooding in the green belt.

[0028] In summary, the utility model can directly utilize river water and hydraulic power to achieve irrigation, and has the advantages of energy saving, environmental protection and good practicality. BRIEF DESCRIPTION OF THE DRAWINGS
