Description

Technical Field

[0001] This utility model relates to the field of greenhouse irrigation technology, and in particular to an agricultural greenhouse water collection and irrigation system. Background Technology

[0002] In greenhouse cultivation, irrigation equipment is often needed to improve irrigation efficiency and water utilization.

[0003] In the prior art, Chinese utility model patent CN 215957435 U discloses an irrigation device for greenhouses in the field of agricultural planting technology, including a walking component and an irrigation component. The walking component includes a path plate, with sliding rods on both sides of the path plate. A sliding groove is fixed at the lower end of the path plate, and a first motor is installed at one end of the sliding groove. A lead screw is provided at the output end of the first motor, and a movable base is threaded onto the surface of the lead screw. A connecting plate is fixed under the movable base. The irrigation component includes a second motor. The placement plate of this utility model is used for the fixed connection of the irrigation component. The water inlet pipe is a corrugated pipe that can extend its service length. The water inlet pipe delivers irrigation water to a buffer bottle to avoid "water bursting." Opening the water valve allows the delivery pipe to deliver water to a distributor, which distributes the water to each mist generator. The mist outlet pipe sprays water mist into the greenhouse. Starting the second motor can drive the placement plate to rotate horizontally, expanding the mist irrigation area.

[0004] While the above technical solution solves the problem of mobile irrigation equipment in greenhouses, the following problems still exist:

[0005] 1) The structure is complex, and the movement is driven by a lead screw motor, which limits the range of movement and makes it difficult to control stability;

[0006] 2) Using a second motor to drive the irrigation equipment to rotate and irrigate can easily lead to excessive watering of crops at the center of rotation, while insufficient watering of crops at the edges.

[0007] Therefore, we need to provide a technical solution that can solve the problem of automatic and uniform irrigation while also taking into account resource utilization and cost savings. Utility Model Content

[0008] This utility model addresses the shortcomings of existing technologies by providing an agricultural greenhouse water collection and irrigation system that can automatically irrigate greenhouse crops and collect rainwater for water supply, thus achieving effective resource utilization and significantly reducing costs.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0010] This utility model provides an agricultural greenhouse water collection and irrigation system, including a greenhouse frame, a sprinkler system installed inside the greenhouse, a water supply pipe for supplying water to the sprinkler system, a water pump assembly for pumping water from the water supply pipe, and a water collection system for collecting rainwater.

[0011] The water collection system includes a water collection trough for collecting rainwater, a water collection pool for storing collected water, and a water collection pipe for connecting the water collection trough and the water collection pool for water transportation. The water collection trough is located at the edge of the roof of the shed or at the edge of the roof of an adjacent shed.

[0012] The inlet end of the water supply pipe is connected to the water collection tank, and the outlet end of the water supply pipe is connected to the sprinkler system.

[0013] The sprinkler system includes several supports installed inside the greenhouse, sprinkler head units evenly arranged and installed on the supports, and water supply pipes connecting the sprinkler head units and the water supply pipes.

[0014] The spray head unit includes several spray heads, a mounting rod for supporting the spray heads, and a connecting seat for connecting the mounting rod and the bracket.

[0015] The bracket is provided with an annular toothed belt, and a rotating pulley is engaged with the inner ring of the annular toothed belt. The rotating pulley is driven by a drive motor. The connecting seat is installed on the annular toothed belt. The bracket is also provided with a slide rail for limiting and supporting the mounting rod.

[0016] The slide rail has a guide groove on its outer ring wall for guiding the water pipe, and a storage groove at the end of the slide rail located on the support for storing the water pipe.

[0017] Each of the aforementioned brackets is equipped with an independent control valve.

[0018] The canopy is equipped with a canopy film for blocking rainwater, and the water collection trough is located below the bottom of the canopy film. The bottom of the water collection trough is equipped with a support rod for supporting and reinforcing the water collection trough.

[0019] The water collection and irrigation system also includes a monitoring component for monitoring the temperature and humidity inside the greenhouse. The monitoring component includes a humidity sensor for monitoring the humidity inside the greenhouse, a temperature sensor for monitoring the temperature inside the greenhouse, and a soil moisture sensor for monitoring soil moisture. The monitoring component also includes an axial flow fan.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides an agricultural greenhouse water collection and irrigation system. The system incorporates a sprinkler system to provide optimal growing conditions for the crops grown in the greenhouse. By deploying the sprinkler system inside the greenhouse, it ensures automatic irrigation for every plant. Water supply pipes and pumps deliver water to the sprinkler system, while the water collection system can store water for daily use and also collect rainwater for irrigation, thus saving water. When collecting rainwater, a collection trough collects natural rainwater. Rainwater falls directly into the trough or drips onto the greenhouse and flows down into the trough for collection. The collected rainwater is then channeled through a collection pipe to a storage tank for use in crop irrigation, effectively saving water and achieving efficient resource utilization. This invention enables automatic irrigation of greenhouse crops and also collects rainwater for water supply, achieving efficient resource utilization and significantly reducing costs.

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0029] refer to Figures 1 to 6As shown, an agricultural greenhouse water collection and irrigation system includes a greenhouse frame 1. It is characterized by comprising a sprinkler system 51 installed within the greenhouse, a water supply pipe 52 for supplying water to the sprinkler system 51, a water pump assembly 53 for pumping water from the water supply pipe 52, and a rainwater collection system 54. The rainwater collection system 54 includes a rainwater collection trough 541, a rainwater storage tank 542, and a water collection pipe 543 connecting the rainwater collection trough 541 and the rainwater storage tank 542 for water transport. The rainwater collection trough 541 is located at the edge of the greenhouse roof of the greenhouse frame 1 or at the edge of the roof of an adjacent greenhouse frame 1. The inlet end of the water supply pipe 52 is connected to the rainwater storage tank 542, and the outlet end of the water supply pipe 52 is connected to the sprinkler system 51.

[0030] This system features a sprinkler system 5 to provide optimal growing conditions for crops grown in the greenhouse. The sprinkler system 51, installed inside the greenhouse, ensures automatic irrigation for every plant. Water supply pipes 52 and a water pump assembly 53 deliver water to the sprinkler system. The water collection system 54 stores water for daily use and collects rainwater for irrigation, conserving water. When collecting rainwater, a collection trough 541 collects natural rainwater. Rainwater falls directly into the collection trough 541, or falls onto the greenhouse and flows down into it. The collected rainwater is then channeled through a collection pipe 543 to a collection tank 542 for storage before being used for crop irrigation. This effectively saves water and achieves efficient resource utilization. This system provides automatic irrigation for greenhouse crops and also collects rainwater for water supply, achieving efficient resource utilization and significantly reducing costs.

[0031] refer to Figure 5 As shown, the sprinkler system 51 includes several supports 511 erected inside the greenhouse, sprinkler head units 512 evenly arranged and installed on the supports 511, and water supply pipes 513 connecting the sprinkler head units 512 and the water supply pipes 52. Multiple sets of supports 511 are set up inside the greenhouse according to the planting location of the crops to ensure that all crops can be irrigated. The sprinkler head units 512 are installed on the supports 511, and water is supplied to the sprinkler head units 512 through the water supply pipes 513, enabling the sprinkler heads to perform irrigation operations. This structure can achieve efficient irrigation operations, and it is automatic irrigation, resulting in more uniform irrigation.

[0032] refer to Figure 5 and Figure 6As shown, the spray head unit 512 includes several spray heads 5121, a mounting rod 5122 for supporting the spray heads 5121, and a connecting seat 5123 for connecting the mounting rod 5122 and the bracket 511. Multiple spray heads 5121 are provided on one spray head unit 512. The spray angle of each spray head 5121 is set according to the actual site conditions, allowing for finer spraying to facilitate simultaneous spraying of a large area. The spray heads 5121 are installed via the mounting rod 5122 and then connected to the bracket 511 via the connecting seat 5123, facilitating adjustment of the installation position of the spray head unit 512.

[0033] refer to Figure 5 and Figure 6 As shown, the bracket 511 is equipped with an annular toothed belt 5111, and the inner ring of the annular toothed belt 5111 is meshed with a rotating pulley 5112. The rotating pulley 5112 is driven by a drive motor 5113. The connecting seat 5123 is mounted on the annular toothed belt 5111. The bracket 511 is also equipped with a slide rail 5114 for limiting and supporting the mounting rod 5122. The drive motor 5113 is a bidirectional rotating motor. The annular toothed belt 5111 drives the connecting seat 5123 to reciprocate, further driving the mounting rod 5122 to move on the slide rail 5114, enabling the spray head unit 512 to perform mobile spraying operations. Compared with a fixed spray head design, this saves equipment usage, and the reduced number of spray heads also reduces the workload of damage maintenance.

[0034] During operation, the drive motor 5113 drives the rotating pulley 5112 to rotate, thereby driving the annular toothed belt 5111 to rotate. At this time, the connecting seat 5123 installed on the annular toothed belt 5111 also drives the spray head unit 512 to perform mobile spraying operation.

[0035] refer to Figure 6 As shown, the outer ring wall of the slide rail 5114 is provided with a guide groove 5115 for guiding the water pipe 513, and the end of the slide rail 5114 located on the bracket 511 is provided with a storage groove 514 for storing the water pipe 513. During the mobile spraying operation, the water pipe 513 moves forward or backward within the guide groove 5115. The guide groove 5115 prevents the water pipe 513 from slipping and also limits its travel path to prevent stacking. Even when the connecting seat 5123 is retracting, the water pipe 513 will not stack.

[0036] refer to Figure 3 As shown, each set of supports 511 is equipped with an independent control valve 516. In this embodiment, the independent control valve 516 facilitates independent irrigation of crops in different locations, making it more flexible and convenient.

[0037] During operation: The water pump assembly 513 and corresponding control valve 516 are turned on. Water from the water collection system 54, under the action of the water pump assembly 513, enters the corresponding water delivery pipe 513 through the water supply pipe 52 and is then transported to the connected sprinkler head unit 512. The drive motor 5113 is started to drive the rotating pulley 5112 to rotate, thereby driving the annular toothed belt 5111 to rotate. At this time, the connecting seat 5123 located on the annular toothed belt 5111 moves together with the annular toothed belt 5111, thereby driving the mounting rod 5122 to slide on the slide rail 5114. At this time, the sprinkler head 5121 set on the mounting rod 5112 sprays water mist onto the crops. However, as the mounting rod 5112 moves, the sprinkler head 5121 performs mobile spraying to complete the irrigation operation of the crops within the set range. After the irrigation operation is completed, simply turn off the water pump assembly 513 to stop the water supply, and then turn off the drive motor and control valve 516.

[0038] refer to Figure 2 As shown, the shed frame 1 is equipped with a shed film 2 for blocking rainwater. The water collection trough 541 is located below the lowest end of the shed film 2, and the bottom of the water collection trough 541 is equipped with a support rod 544 for supporting and reinforcing the water collection trough 541. By placing the water collection trough 541 below the lowest end of the shed film 2, rainwater falling on the shed film 2 flows downwards along the curvature of the shed film 2 into the water collection trough 541, which can maximize the collection of rainwater for resource utilization. The water collection trough 541 can also be set between the expansion bodies of two greenhouses to reduce equipment costs.

[0039] refer to Figure 2 As shown, the water collection and irrigation system also includes a monitoring component 6 for monitoring the temperature and humidity inside the greenhouse. The monitoring component 6 includes a humidity sensor 61 for monitoring humidity, a temperature sensor 62 for monitoring temperature, and a soil moisture sensor for monitoring soil moisture. The monitoring component 6 also includes an axial flow fan 63. In this embodiment, the humidity sensor 61, temperature sensor 62, and soil moisture sensor jointly monitor the crop growth environment inside the greenhouse and feed the monitoring data back to the control unit. This allows the control unit to control the sprinkler system 51 to achieve automatic irrigation. The axial flow fan 63 is mainly used for ventilation, cooling, and temperature and humidity regulation. Through the effective operation of the axial flow fan, the temperature inside the greenhouse can be significantly reduced, creating a more suitable environment for crop growth. Combined with the temperature sensor 62, this ensures the optimal growth environment for the crops.

[0040] One implementation method: During operation, the monitoring component 6 detects real-time data such as temperature, humidity, and soil moisture in the greenhouse and feeds it back to the control unit. After analyzing the data, the control unit sends a command to the water pump component 53 to start according to the set threshold. The water supply pipe 52 starts supplying water and the sprinkler component 51 starts the sprinkler watering operation. The stop time is determined according to the set water supply volume or irrigation time to complete the irrigation operation.

[0041] Another implementation method: Pre-set the irrigation time, water volume and irrigation duration to carry out timed irrigation operations.
