Description

Technical Field

[0001] The invention relates to the field related to drought-resistant cultivation of chestnuts, and in particular to a rainwater collection device for drought-resistant chestnuts and a collection method thereof. Background Art

[0002] As an important dried fruit and economic forest tree species, chestnuts not only boast nutritious fruits rich in starch, protein, vitamins, and various minerals, possessing high edible value and health benefits, but also play a vital role in timber utilization and ecological protection. Chestnuts grow in mountainous areas, where most orchards lack irrigation. Droughts severely impact the growth and fruiting of chestnut trees. In recent years, frequent droughts have occurred in chestnut-producing areas, resulting in small chestnuts, poor quality, and low yields, impacting farmers' incomes. Chestnuts have a certain water requirement during their growth, but these requirements vary at different stages of growth. During the budding stage, chestnut trees require an adequate amount of water to promote bud germination and new shoot growth. The flowering stage is a critical period for chestnut growth, and an adequate water supply helps maximize fruit set. During the fruit expansion stage, a high amount of water is required to meet the needs of fruit development. Insufficient water during this period results in slow fruit growth and reduced quality. However, chestnut trees possess a certain degree of drought tolerance and can adapt to arid environments to a certain extent. However, long-term drought stress will have an adverse effect on the growth and development of chestnut trees, such as causing leaves to turn yellow and fall off, poor branch growth, and even affecting the survival of the tree.

[0003] In drought years, insufficient water supply inhibits the physiological activities of chestnut trees, weakening photosynthesis and hindering nutrient absorption and transport. This leads to poor flower bud differentiation, reduced fruit set, and poor fruit development, ultimately resulting in a significant drop in chestnut yield. Drought also negatively impacts chestnut quality. Insufficient water reduces the accumulation of nutrients like sugar and starch within the fruit, resulting in smaller fruits, thicker skin, and a poorer taste.

[0004] Rainwater collection is an ancient and effective way of utilizing water resources. It can collect natural precipitation and use it for agricultural irrigation, domestic water use, etc. In the agricultural field, rainwater collection technology has been widely used. In view of the serious impact of drought on chestnut planting and the wide application prospects of rainwater collection technology in the agricultural field, it is of great practical significance to apply rainwater collection devices to tree irrigation. For example, the Chinese authorized patent with announcement number CN212877013U (202021208682.2 Garden Rainwater Collection Device): includes a water tank, a drain pipe connected to the water tank, a water pump arranged on the drain pipe, and a sprinkler pipe connected to one end of the drain pipe away from the water tank, a plurality of water spray holes are provided on the side of the sprinkler pipe away from the water tank, the sprinkler pipes are distributed around the water tank, and support frames for supporting the sprinkler pipes are provided around the water tank. The technical effect of the utility model is that the plants around the water tank can be watered, which effectively expands the watering range of the plants and improves the efficiency of plant watering.

[0005] Although the above-mentioned existing technology has the function of collecting rainwater for vegetation irrigation, the chestnut trees in the chestnut orchard are trees. The open rainwater collection structure will cause the leaves, branches, and some fruits of the chestnut trees to fall into the collection structure, resulting in too much debris in the collection structure, which will affect the discharge and use of the collected rainwater during the rainy season.

A water collecting chamber is formed inside the upper water collecting tank along the lower end of the filter assembly.

[0010] Preferably, an intermediate fixed column is fixed at the center of the upper end of the intermediate plate, and an upper fixed plate is fixed to the upper end of the intermediate fixed column.

[0016] A collection method comprises the following steps:

[0017] Step 1: The output rod end of the driving cylinder contracts, driving the rainwater output pipe, the upper actuating plate, the upper water collecting tank and the upper structure of the upper water collecting tank to move downward;

[0018] Step 2: When one end of the middle action rod is driven to move downward, the middle action rod rotates outward as a whole, pushing the rotating adjustment rod to rotate outward and open, and the rainwater collecting cloth fixed by multiple rotating adjustment rods is opened;

[0019] Step 3: As the rubber shielding ring plate moves downward and the rainwater collecting cloth expands outward, the rainwater collecting cloth opens outward from the lower end of the rubber shielding ring plate, forming a rainwater collecting area between the rainwater collecting cloth and the rubber shielding ring plate;

[0020] Step 4: Rainwater flows along the rainwater collection cloth to the upper end of the filter assembly inside the upper water collection tank. The fallen leaves and impurities in the rainwater move toward the annular filter along the inward and outward filter screens due to the influence of gravity and the downward flow of rainwater, and accumulate on the upper end of the annular filter screen. The rainwater is filtered through the inward, annular and outward filter screens and then enters the water collection chamber.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) In this invention, when it rains, the output rod end of the driving oil cylinder contracts, driving the rainwater output pipe, the upper action plate, the upper water collecting box and the upper structure to move downward, pushing the rotating adjustment rod to rotate outward and open, and the rainwater collecting cloth is then unfolded, forming a larger rainwater collecting area, which can quickly collect rainwater, greatly improving the rainwater collection efficiency and providing a sufficient water source for the chestnut orchard during the dry season. When the rain stops, the output rod end of the driving oil cylinder is controlled to extend, driving the rainwater collecting cloth and the rotating adjustment rod to contract inward, and finally contracting to the limit state. The rubber shielding ring plate is reset to form an umbrella shape at its upper end, shielding the gap formed by the contraction of the upper end of the rainwater collecting cloth. Impurities such as leaves, branches, and parts of fruits will not fall into the device in the normal non-collection state, preventing them from entering the collection structure and affecting the collection and discharge of rainwater during use, and preventing them from clogging the filter structure when not in use, thereby affecting the filtering effect during rainwater collection.

[0023] (2) In this invention, by cooperating with the supporting base plate, the embedded fixed pointed feet, and the oblique reinforcement points, the device can be flexibly installed according to the terrain of the chestnut orchard. The embedded fixed pointed feet and the oblique reinforcement points are embedded in the soil, providing stable support for the device, ensuring that the device can be stably placed in various terrains, greatly improving the applicability and stability of the device. Moreover, by loosening the fixing bolts, adjusting the relative position of the middle connecting plate, and adjusting the relative positions of the outer adjustment sleeve and the inner adjustment rod, the device can adapt to the ground with different degrees of inclination, maintaining the normal vertical placement of the structure above the middle connecting plate. In the sloping environment of the chestnut orchard, it is not limited by the inclination of the ground, providing a good foundation for subsequent rainwater collection work, and improving the accuracy and reliability of the device installation.

[0024] (3) In this invention, the collected rainwater is filtered through the inward filter, the annular filter, and the outward filter, which can effectively remove impurities such as fallen leaves in the rainwater, thereby ensuring the quality of the collected rainwater. The shapes of the inward filter, the annular filter, and the outward filter are designed so that the fallen leaves in the rainwater move along the inward filter and the outward filter toward the annular filter due to the influence of gravity and the downward flow of rainwater, and accumulate on the upper end of the annular filter, thereby reducing the blockage of the inward filter and the outward filter, thereby ensuring the rainwater collection effect.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figures 1-8 The present invention provides an embodiment: a rainwater collection device for chestnut drought resistance, which mainly includes a driving cylinder 11, a rainwater output pipe 12, a rainwater discharge pipe 14, a fixed vertical pole 15, an upper connecting plate 16, a rotating adjustment rod 18, an upper action plate 20, an intermediate action rod 22, an upper water collecting box 23, a filter assembly 26, a rubber shielding ring plate 38, a rainwater collecting cloth 39 and other structures.

[0036] Second fixing seats 8 are welded and fixed to both sides of the lower end of the intermediate connecting plate 10. One end of an inner adjustment rod 7 is rotatably connected to the inner side of the second fixing seat 8 via an axis. The other end of the inner adjustment rod 7 extends into the interior of the outer adjustment sleeve 6 and is telescopically connected to the outer adjustment sleeve 6. The other end of the outer adjustment sleeve 6 extends into the first fixing seat 5 and is rotatably connected to the first fixing seat 5 via an axis. The lower ends of the two first fixing seats 5 are jointly fixed to both sides of the upper end of the support base plate 1. The inner adjustment rod 7 and the outer adjustment sleeve 6 are fixed by fixing bolts 9. By adjusting the relative position of the outer adjustment sleeve 6 and the inner adjustment rod 7, the entire body formed by the outer adjustment sleeve 6 and the inner adjustment rod 7 can be correspondingly extended or contracted.

[0037] The lower end of the support base 1 is fixed with an array of embedded fixed pointed feet 2, and the outer array of the embedded fixed pointed feet 2 is fixed with oblique reinforcement tips 3, which are set obliquely. The front end of the upper end of the support base 1 is installed with an equipment box 4. The electrical structures used in this device, such as control equipment, battery packs or direct power supply lines, hydraulic oil tanks, hydraulic oil drive equipment, etc., are installed in the equipment box 4. The battery pack provides power support for the device; a better way to power the device is to lead wires from the outside so that the wires are connected to the electrical structure in the equipment box 4 for power supply. In addition, basic structures such as ventilation and heat dissipation holes are opened on the surface of the equipment box 4. Since the equipment box 4 is directly purchased and adaptively installed according to the electrical structure, it is difficult to unify the internal and external structures of the equipment box 4. The attached figure only briefly illustrates its installation position, and does not provide a specific description of the equipment box itself and its internal structure.

[0038] When installing this device, first place this device in an open area in the chestnut forest, and adjust this device according to the inclination of the soil surface. First, place the embedded fixed pointed foot 2 in the installation position, then hit the supporting base plate 1 downward so that the embedded fixed pointed foot 2 and the oblique reinforcement point 3 are embedded in the soil, and the supporting base plate 1 is in contact with the ground. Then tamp the nearby soil and use cement for secondary reinforcement to ensure the stability of the device. Loosen the fixing bolts 9, adjust the relative position of the intermediate connecting plate 10 so that the intermediate connecting plate 10 is in a horizontal state, and then adjust the relative position of the outer adjustment sleeve 6 and the inner adjustment rod 7 so that the overall structure formed by the outer adjustment sleeve 6 and the inner adjustment rod 7 is correspondingly extended or contracted, and then fixed with the fixing bolts 9 to keep the structure above the intermediate connecting plate 10 in a normal vertical position.

[0039] This device is installed in several chestnut orchards, and one or more rainwater collection tanks are installed in low-lying areas. The output end of the rainwater discharge pipe 14 is connected to the input end of the rainwater collection tank; or a transfer pump is installed in the middle to pump the collected water into the rainwater collection tank. The output end of the rainwater collection tank is connected to the irrigation pipe through a pipe and a pumping structure. During droughts, the collected rainwater can be used for irrigation, providing a sufficient water source for the chestnut orchard.

[0040] A driving cylinder 11 is centrally mounted at the lower end of the intermediate connecting plate 10. A rainwater outlet pipe 12 is secured to the upper end of the intermediate connecting plate 10, along the output rod end of the driving cylinder 11. Fixed vertical rods 15 are secured to the outer portion of the upper end of the intermediate connecting plate 10 in a cross-shaped pattern. An upper connecting plate 16 is secured to the upper ends of multiple fixed vertical rods 15. The outer surface of the upper connecting plate 16 is provided with a first rotation slot 17 arrayed therein. A rotation adjustment rod 18 is pivotally connected to the first rotation slot 17 via a shaft. A third fixing seat 19 is secured to the lower end of the inner end of the rotation adjustment rod 18. An intermediate actuating rod 22 is pivotally connected to the inner end of the third fixing seat 19 via a shaft. The upper end of the rainwater outlet pipe 12 passes through the upper connecting plate 16 and is secured to the upper actuating plate 20. The rainwater outlet pipe 12 is slidably connected to the upper connecting plate 16. A second rotation slot 21 arrayed therein is provided on the outer surface of the upper actuating plate 20. The other end of the intermediate actuating rod 22 extends into the second rotation slot 21 and is pivotally connected to the upper actuating plate 20 via a shaft. An upper water collecting tank 23 is fixed to the upper end of the upper operating plate 20, and the upper water collecting tank 23 is connected to the interior of the rainwater output pipe 12. An outer limiting ring 13 is fixed to the lower end of the outer portion of the rainwater output pipe 12. A rainwater discharge pipe 14 is installed at the rear end of the outer portion of the rainwater output pipe 12 along the lower end of the outer limiting ring 13, and the rainwater discharge pipe 14 extends to the rear end.

[0041] When it rains, the output rod end of the drive cylinder 11 retracts, driving the rainwater outlet pipe 12, the upper actuating disc 20, the upper water collecting tank 23, and the upper structure of the upper water collecting tank 23 downward. Driven by the retraction of the output rod end of the drive cylinder 11, the upper actuating disc 20 moves downward, and one end of the intermediate actuating rod 22 is also driven downward, rotating the entire structure outward, pushing the rotating adjustment levers 18 to rotate outward and open. A rainwater collection sheet 39 is secured to the upper ends of the inner ends of the multiple rotating adjustment levers 18. The inner ends of the rainwater collection sheets 39 extend to the inner wall of the upper water collecting tank 23 and are connected to the upper water collecting tank 23. As the rotating adjustment levers 18 are opened, the rainwater collection sheets 39 are deployed. An embedded annular groove 24 is defined in the upper end surface of the inner wall of the upper water collecting tank 23. The inner end of the rainwater collection sheet 39 is fixed within this embedded annular groove 24. A fixed inner ring 25 is formed along the inner end of the embedded annular groove 24 on the inner wall of the upper water collecting tank 23. A filter assembly 26 is disposed at the upper end of the fixed inner ring 25.

[0042] The upper end of the intermediate disk 31 is fixed with an intermediate fixed column 34 in the center, and the upper end of the intermediate fixed column 34 is fixed with an upper fixed disk 35. The outer annular array of the upper fixed disk 35 is fixed with an inclined fixed plate 37. The inclined fixed plate 37 is staggered with the rotating adjustment rod 18 (as shown in the attached figure). Figure 5 A rubber shielding ring 38 is fixed to the upper end of the inclined fixing plate 37 on the exterior of the upper fixing plate 35. The rubber shielding ring 38 is secured to the inclined fixing plate 37. A mushroom-shaped cap 36 is integrally connected to the upper end of the upper fixing plate 35. The outer edge of the cap 36 has an arc-shaped inward-retracting portion, which provides a certain degree of shielding, preventing rainwater from directly eroding the internal structure of the device.

[0043] As the rubber shielding ring plate 38 moves downward and the rainwater collecting cloth 39 expands outward, the rainwater collecting cloth 39 opens outward from the lower end of the rubber shielding ring plate 38 , forming a rainwater collecting area between the rainwater collecting cloth 39 and the rubber shielding ring plate 38 . Rainwater flows along the rainwater collecting cloth 39 to the interior of the upper water collecting tank 23 along the upper end of the filter assembly 26. The filter assembly 26 is composed of an outer ring body 27, an inward filter screen 28, an annular filter screen 29, an outward filter screen 30 and an intermediate disk 31. The outer ring body 27, the inward filter screen 28, the annular filter screen 29, the outward filter screen 30 and the intermediate disk 31 are arranged from outside to inside. The inward filter screen 28 is tilted inward and downward, the annular filter screen 29 is horizontally arranged, and the outward filter screen 30 is tilted inward and upward. Filter holes are provided on the inward filter screen 28, the annular filter screen 29 and the outward filter screen 30. The outer ring body 27 is located at the upper end of the fixed inner ring body 25 and is fixed to the fixed inner ring body 25 by screws. A water collecting chamber 33 is formed inside the upper water collecting tank 23 along the lower end of the filter assembly 26. The fallen leaves and impurities in the rainwater move toward the annular filter 29 along the inward-retracting filter 28 and the outward-expanding filter 30 due to the influence of gravity and the downward flow of rainwater, and accumulate at the upper end of the annular filter 29. The rainwater is filtered through the inward-retracting filter 28, the annular filter 29 and the outward-expanding filter 30 and enters the water collection chamber 33, and enters the rainwater collection tank along the rainwater output pipe 12 and the rainwater discharge pipe 14, thereby ensuring the quality of the collected rainwater.

[0044] When the rain stops, the output rod end of the control driving cylinder 11 is extended, the rainwater output pipe 12, the upper action plate 20, the upper water collecting tank 23 and the upper structure of the upper water collecting tank 23 move upward, and the rotating adjustment rod 18 is driven to retract inward, driving the rainwater collecting cloth 39 to retract inward. As the output rod end of the driving cylinder 11 extends, the rainwater collecting cloth 39 and the rotating adjusting rod 18 are not completely retracted, but the rainwater collecting cloth 39 and the rotating adjusting rod 18 are located outside the rubber shielding ring plate 38 and contact the rubber shielding ring plate 38; then as the output rod end of the driving cylinder 11 continues to extend, the rainwater collecting cloth 39 and the rotating adjusting rod 18 press the rubber shielding ring plate 38 to move inward, and the rubber shielding ring plate 38 is deformed in the process; as the output rod end of the driving cylinder 11 continues to extend, the rainwater collecting cloth 39 and the rotating adjusting rod 18 break through the rubber shielding ring plate 38 and reach the lower end of the rubber shielding ring plate 38 and shrink to the limit state, the rubber shielding ring plate 38 is reset to form an umbrella shape and located at the upper end of the rainwater collecting cloth 39 and the rotating adjusting rod 18, and the gap formed by the shrinkage of the upper end of the rainwater collecting cloth 39 is blocked by the rubber shielding ring plate 38.

[0045] The collection method of the present invention comprises the following steps:

[0046] Step 1: The output rod end of the driving cylinder 11 contracts, driving the rainwater output pipe 12, the upper actuating plate 20, the upper water collecting tank 23 and the upper structure of the upper water collecting tank 23 to move downward;

[0047] Step 2: When one end of the intermediate action rod 22 is driven to move downward, the intermediate action rod 22 rotates outward as a whole, pushing the rotating adjustment rod 18 to rotate outward and open, and the rainwater collecting cloth 39 fixed by multiple rotating adjustment rods 18 is opened;

[0048] Step 3: As the rubber shielding ring plate 38 moves downward and the rainwater collecting cloth 39 expands outward, the rainwater collecting cloth 39 opens outward from the lower end of the rubber shielding ring plate 38, forming a rainwater collecting area between the rainwater collecting cloth 39 and the rubber shielding ring plate 38;

[0049] Step 4: Rainwater flows along the rainwater collecting cloth 39 to the interior of the upper water collecting box 23 along the upper end of the filter assembly 26. The fallen leaves and impurities in the rainwater move toward the annular filter 29 along the inward filter 28 and the outward filter 30 due to the influence of gravity and the downward flow of rainwater, and accumulate at the upper end of the annular filter 29. The rainwater is filtered through the inward filter 28, the annular filter 29 and the outward filter 30 and then enters the water collecting chamber 33.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
