Water-saving device for greenhouse planting

Abstract

This utility model discloses a water-saving device for greenhouse cultivation, belonging to the field of dragon fruit cultivation technology. It aims to address the problem that existing water-saving measures in greenhouse cultivation often focus on rainwater harvesting, but this single method is insufficient to meet long-term needs. Firstly, the capacity of existing collection facilities is generally inadequate. Even in rainy weather, the lack of matching large-capacity collection equipment results in a significant amount of rainwater being wasted, failing to provide a stable water source for long-term irrigation. Secondly, the uncertainty of climatic conditions further highlights the limitations of rainwater harvesting. In dry seasons, rainwater harvesting facilities become "waterless" due to the lack of effective rainfall replenishment. At this time, to ensure crop irrigation, growers have to use external water sources such as tap water, which contradicts the original intention of water conservation and makes the water-saving model relying solely on rainwater harvesting unsustainable. This invention applies to dragon fruit greenhouses.

Description

Technical Field

[0001] This utility model belongs to the field of dragon fruit planting technology, specifically relating to a water-saving device for greenhouse planting. Background Technology

[0002] Dragon fruit is a perennial climbing succulent plant that is very popular. In order to be able to eat it in different seasons, it usually needs to be grown in greenhouses.

[0003] Current water-saving measures commonly used in greenhouse cultivation mostly focus on rainwater harvesting. However, this single approach is insufficient to meet long-term needs. On the one hand, the capacity of existing collection facilities is generally inadequate. Even in rainy weather, a large amount of rainwater is lost due to the lack of matching large-capacity collection equipment, failing to provide a stable water source for long-term irrigation. On the other hand, the uncertainty of climate conditions further highlights the limitations of rainwater harvesting. In dry seasons, rainwater harvesting facilities become "water without a source" due to the lack of effective rainfall replenishment. At this time, in order to ensure crop irrigation, growers have to use external water sources such as tap water, which runs counter to the original intention of water conservation and makes the water-saving model that relies solely on rainwater harvesting unsustainable. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a water-saving device for greenhouse cultivation. This device aims to solve the problem that existing water-saving measures in greenhouse cultivation often focus on rainwater harvesting, but this single approach is insufficient to meet long-term needs. Firstly, the capacity of existing harvesting facilities is generally inadequate. Even in rainy weather, the lack of matching large-capacity harvesting equipment results in a significant amount of rainwater being wasted, failing to provide a stable water source for long-term irrigation. Secondly, the uncertainty of climatic conditions further highlights the limitations of rainwater harvesting. During dry seasons, rainwater harvesting facilities become "waterless" due to the lack of effective rainfall replenishment. In such cases, to ensure crop irrigation, growers have to use external water sources such as tap water, which contradicts the original intention of water conservation and makes the water-saving model relying solely on rainwater harvesting unsustainable.

An irrigation mechanism is installed on one side and above the middle of the underground water storage tank. The water-saving component includes a guide water pipe, and the end of the guide water pipe is connected to a filter box. The filter box is equipped with a filter component inside. An external water pipe is connected to the upper side of the underground water storage tank.

[0008] Furthermore, the water-saving component includes a partitioned water collection frame, which is fixedly mounted on the top of a plurality of second support frames. A first guide plate is fixedly installed in the V-shaped groove of the partitioned water collection frame, and a main water collection frame is fixedly connected to one side of the partitioned water collection frame. Second guide plates are fixedly installed on both sides of the middle part of the main water collection frame, and a guide water pipe is connected to the middle of the bottom end of the main water collection frame.

[0009] Furthermore, the partitioned water collection frame is composed of multiple V-shaped frames connected together, and a first guide plate is fixedly installed in the groove of each of the multiple V-shaped frames.

[0010] Furthermore, the second guide vanes are symmetrically distributed along the vertical central axis of the main water collection frame, and the two second guide vanes are designed to be inclined relative to each other.

[0011] Furthermore, the filter assembly includes an embedded slot frame, which is fixed inside the lower section of the filter box.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In dragon fruit greenhouses, temperatures are typically higher than outside, especially at night or on rainy days. Because the inner wall temperature of the greenhouse film is lower than the dew point temperature of the air inside, a large amount of condensation forms on the inner wall. To effectively collect this condensation, a zoned water collection rack is installed below the greenhouse. This rack consists of multiple V-shaped troughs. When condensation falls, the zoned racks collect it and guide it to the main collection rack via a first guide plate. In the main collection rack, two opposing second guide plates guide the condensation through guide pipes into a filter box. The filter box contains a filtration area composed of a filter frame and a conical filter frame, effectively removing impurities from the water. Upon contact with the conical filter frame, impurities are carried down the slope... The water naturally slides onto the filter rack. Subsequent workers simply need to open a door on one side of the filter box to remove the filter rack and cone-shaped filter for cleaning. The filtered water then flows through a collection pipe into an underground water storage tank for later use. This design not only achieves effective water recycling but also prevents continuous dripping of condensate from damaging the dragon fruit leaves and fruit. Notably, the underground water storage tank is buried underground, effectively preventing water evaporation caused by high summer temperatures. Furthermore, a water level sensor is installed inside the underground water storage tank. When the water level drops to a preset value, the sensor activates an electrically controlled solenoid valve to replenish the underground water storage tank with self-contained water via an external water pipe, ensuring a continuous supply of irrigation water.

[0018] When irrigation of dragon fruit is required, the operator starts the water pump with a protective outer shell. This protective shell can effectively resist the corrosion of the water pump by harsh weather and ensure the stable operation of the equipment. After starting, the water pump transports the water stored in the underground water tank to the sprinkler frame in an orderly manner through the first and second connecting pipes. The sprinklers evenly distributed below the sprinkler frame will spray the water in an atomized or drip irrigation manner, accurately covering the dragon fruit planting area, thereby efficiently completing the irrigation operation.

[0025] 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.

[0026] This specific embodiment is a water-saving device for greenhouse cultivation, and its structural schematic diagram is shown below. Figures 1 to 4As shown, the dragon fruit planting greenhouse 1 includes multiple first support frames 2 internally, and multiple second support frames 3 internally. A water-saving mechanism 4 is installed on the top of the multiple second support frames 3 and on the interior and exterior of the dragon fruit planting greenhouse 1. The water-saving mechanism 4 includes a water-saving component 41, a water collection pipe 436, and an external water pipe 44. The ends of the water collection pipe 436 and the external water pipe 44 are connected to an underground water storage tank 5. An irrigation mechanism 6 is installed on one side and above the middle of the underground water storage tank 5. The water-saving component 41 includes a zoned water collection rack 411, which is fixedly mounted on the top of the multiple second support frames 3. A first guide plate 412 is fixedly installed in the V-shaped groove of the zoned water collection rack 411. The water collection frame 411 is composed of multiple V-shaped frames connected together, and a first guide plate 412 is fixedly installed in the groove of the multiple V-shaped frames. A main water collection frame 413 is fixedly connected to one side of the partitioned water collection frame 411. Second guide plates 414 are fixedly installed on both sides of the middle part of the main water collection frame 413. A guide water pipe 415 is connected to the middle of the bottom end of the main water collection frame 413. The second guide plates 414 are symmetrically distributed along the vertical central axis of the main water collection frame 413, and the two second guide plates 414 are designed to be inclined relative to each other. The end of the guide water pipe 415 is connected to a filter box 42. A filter assembly 43 is installed inside the filter box 42. The filter assembly 43 includes an embedded groove frame 431, which is fixedly installed in the lower part of the filter box 42. The upper middle part of the embedded groove frame 431 is embedded in the filter assembly 431. The system is equipped with a filter frame 432, and a conical filter frame 433 is installed above the filter frame 432. Handles 434 are fixed on both sides of the upper part of the filter frame 432. A water guide cover 435 is connected to the lower part of the embedded groove frame 431, and a water collection pipe 436 is connected to the bottom of the water guide cover 435. The embedded groove frame 431 and the filter frame 432 are detachably embedded, while the filter frame 432 and the conical filter frame 433 are fixedly connected. An external water pipe 44 is connected to one side of the upper part of the underground water storage tank 5. At night or on rainy days, the temperature inside the dragon fruit greenhouse 1 is usually higher than the outside temperature. Because the temperature of the inner wall of the greenhouse film is lower than the dew point temperature of the air inside the greenhouse, a large amount of condensate will be generated on the inner wall of the greenhouse film. In order to effectively collect this condensate, a zoned collection system is set up at the bottom of the greenhouse. The water collection rack 411, composed of multiple V-shaped troughs, receives condensate water as it falls. The first guide plate 412 then transports it to the main water collection rack 413. In the main water collection rack 413, two opposing second guide plates 414 guide the condensate water through the guide pipe 415 into the filter box 42. The filter box 42 contains a filtration area composed of a filter frame 432 and a conical filter frame 433, effectively removing impurities from the water. Impurities, upon contact with the conical filter frame 433, naturally slide down the slope onto the filter frame 432. Subsequent cleaning can be achieved by simply opening a door on one side of the filter box 42 and removing the filter frame 432 and conical filter frame 433. The filtered water is then ready for use.The water will then flow through the collection pipe 436 into the underground water storage tank 5 for storage and backup. This design not only achieves effective water recycling but also avoids damage to the dragon fruit leaves and fruits caused by continuous dripping condensate. It is worth noting that the underground water storage tank 5 is buried underground, effectively preventing water evaporation caused by high summer temperatures. Furthermore, a water level sensor is installed inside the underground water storage tank 5. When the water level drops to a preset value, the sensor will activate an electrically controlled solenoid valve to replenish the underground water storage tank 5 with self-used water via the external water pipe 44, ensuring a continuous supply of irrigation water.

[0027] The irrigation mechanism 6 includes a first connecting pipe 61, which runs through one side of the middle of the underground water storage tank 5. A water pump 62 is connected to one end of the first connecting pipe 61, and a second connecting pipe 63 is connected to the other end of the water pump 62. A sprinkler frame 64 is installed at the end of the second connecting pipe 63. The sprinkler frame 64 is located inside the dragon fruit planting greenhouse 1 and is supported and fixed by a fixed frame. Sprinklers are connected to the bottom of the sprinkler frame 64. When it is necessary to irrigate the dragon fruit, the operator starts the water pump 62, which is protected by a shell. This protective shell can effectively resist the corrosion of the water pump 62 by harsh weather and ensure the stable operation of the equipment. After starting, the water pump 62 transports the water stored in the underground water storage tank 5 to the sprinkler frame 64 in an orderly manner through the first connecting pipe 61 and the second connecting pipe 63. The sprinklers evenly distributed below the sprinkler frame 64 spray water in an atomized or drip irrigation manner, accurately covering the dragon fruit planting area, thereby efficiently completing the irrigation operation.

[0028] Working principle: At night or on rainy days, the temperature inside the dragon fruit greenhouse 1 is usually higher than the outside temperature. Because the temperature of the inner wall of the greenhouse film is lower than the dew point temperature of the air inside, a large amount of condensate will form on the inner wall of the film. To effectively collect this condensate, a zoned water collection rack 411 is installed below the greenhouse. This water collection rack consists of multiple V-shaped troughs. When the condensate falls, the zoned water collection rack 411 can receive it and transport it to the main water collection rack 413 through the first guide plate 412. In the main water collection rack 413, two opposing second guide plates... Plate 414 guides condensate water through guide pipe 415 into filter box 42. Filter box 42 contains a filtration area composed of filter frame 432 and conical filter frame 433, which effectively removes impurities from the water. Impurities, upon contact with conical filter frame 433, will naturally slide down the slope onto filter frame 432. Subsequent cleaning can be performed by simply opening a door panel on one side of filter box 42 and removing filter frame 432 and conical filter frame 433. The filtered clean water will then flow down collection pipe 4... Water 36 is discharged into the underground water storage tank 5 for storage and backup. This design not only achieves effective recycling of water resources, but also avoids damage to dragon fruit leaves and fruits caused by continuous dripping of condensate. It is worth noting that the underground water storage tank 5 is buried underground, which can effectively avoid water evaporation caused by high summer temperatures. In addition, a water level sensor is installed in the underground water storage tank 5. When the water level drops to a preset value, the sensor will use an electrically controlled solenoid valve to replenish the underground water storage tank 5 with self-used water through the external water pipe 44, ensuring a continuous supply of irrigation water. Secondly, when it is necessary to irrigate the dragon fruit, the operator starts the water pump 62 with a protective shell. This protective shell can effectively resist the corrosion of the water pump 62 by harsh weather and ensure the stable operation of the equipment. After starting, the water pump 62 transports the water stored in the underground water storage tank 5 to the sprinkler frame 64 in an orderly manner through the first connecting pipe 61 and the second connecting pipe 63. The sprinklers evenly distributed below the sprinkler frame 64 will spray water in an atomized or drip irrigation manner, accurately covering the dragon fruit planting area, thereby efficiently completing the irrigation operation.
