Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection, and more specifically, particularly relates to a portable, electricity-free and foldable high-efficiency rainwater collector. Background Art

[0002] Rainwater collection is mostly used in fields such as atmospheric activity monitoring and research, water quality analysis, and water cycle research, involving related industries such as atmospheric science, hydrology and water resources engineering, and environmental engineering. For the collection of solid precipitation such as snow and hail, it is usually directly collected with less difficulty; while rainwater is liquid water in a fluid state. Some researchers indirectly study the characteristics of rainwater by collecting surface water accumulation and small streams. However, the surface water accumulation and small streams have obviously been polluted by surface substances and can no longer accurately reflect the characteristics of rainwater. Therefore, the collection of rainwater must be completed with the help of tools.

[0003] China has a vast territory, and there are significant differences in population density, transportation convenience, communication convenience, power grid coverage, rainfall characteristics, etc. in different regions. Most of the existing rainwater collection instruments are of cuboid structure. For example, a rainwater collector with the publication number CN211504858U and an initial rainwater automatic collection device with the publication number CN206038370U. The rainwater collectors with cuboid structure have a slow rainwater collection speed, are inconvenient to use, and most rainwater collectors require power support. Although automatic collection is achieved, the battery life is limited, and the portability is poor. Even if they can be folded, the weight is relatively large. Therefore, there is a need to propose an effective rainwater collector with a short single collection duration, foldability, weight reduction, and electricity-free. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As Figures 1 - 5 shown, the present invention provides a portable electric-free foldable high-efficiency rainwater collector, including: a water collection cloth 1, the water collection cloth 1 is in an inverted conical shape as a whole, and an opening is provided at the central position; a conduit 6, the conduit 6 is connected below the water collection cloth 1 through a seal 9, the inside of the conduit 6 is a hollow structure, the conduit 6 communicates with the central opening of the water collection cloth 1, a slip ring 7 is provided on the conduit 6, and the position of the slip ring 7 is fixed by a locking member 4, and the locking member 4 is provided on the slip ring 7; a support member, the support member is hinged between the outside of the water collection cloth 1 and the slip ring 7.

[0025] The water collection cloth 1 is in an inverted conical shape, and the top view of the unfolded water collection cloth 1 is circular, which is beneficial to collecting rainwater and improving the sampling efficiency. When the water collection cloth 1 is opened, the inverted conical water collection surface is made of a non-water-soluble lotus leaf type water-repellent dense fabric, so that the collected water is not hung on the water collection surface and leaked, or evaporated, which can improve the water collection efficiency; a binding band 12 is provided at the lower surface of the water collection cloth 1 near the fabric edge for tidying and bundling the water collection cloth 1 after the instrument is folded. A support member is provided below the water collection cloth 1 to make the water collection cloth 1 flat, stable, and uniform after being unfolded.

[0026] The support member includes a plurality of first keels 2 and a plurality of second keels 10. The first keels 2 are evenly pasted on the lower surface of the water collection cloth 1. The first keels 2 are made of stainless steel material and have a certain elasticity. The cross-section is circular. The length of the first keel 2 is the same as the radius of the water collection cloth 1. In order to balance the water collection efficiency and wind resistance, the preferred range is 0.5-0.9 meters, and the number is preferably 8-12. The horizontal projection angle between the first keels 2 is obtained by dividing 360 degrees by the number of roots; one end of the second keel 10 is hinged to the middle of the first keel 2 through a first hinge chain 11, and the other end is hinged to the slip ring 7 through a second hinge chain 8. The second keel 10 is also made of stainless steel or alloy material, and the cross-section is U-shaped, which is used to connect the slip ring 7 and the first keel 2. The U-shaped design is to prevent the first keel 2, the second keel 10, and the cloth surface from rotating around the axis in any state. At the same time, setting it in a U-shaped structure can enhance the shear force of the second keel 10 and enhance the supporting effect of the second keel 10.

[0027] The conduit 6 is made of stainless steel or alloy material and has a sturdy property to support the upper water collection cloth 1, the first keel 2, and the second keel 10. The inner side of the conduit 6 has a non-water-soluble wall surface to prevent rainwater from flowing through and carrying dissolved substances, ensuring that the water at the water outlet is pure rainwater. The top of the conduit 6 fixes the water collection cloth 1 through a seal 9, making the opening at the center of the water collection cloth 1 communicate with the inside of the conduit 6. The seal 9 is a seal ring structure. In this embodiment, the seal ring is composed of two semi-circular rings and bolts. The two semi-circular rings are clamped at the connection of the water collection cloth 1 and the conduit 6. The opening of the water collection cloth 1 is sleeved on the outer wall of the top of the conduit 6. Tighten the bolts to fix the two semi-circular rings, realizing the fixation between the water collection cloth 1 and the conduit 6. The seal ring adopts the structure in the prior art, and the specific model is SCSP or SSCSP or SCNPA; the seal 9 can also use thermoplastic glue and iron wire. Place the thermoplastic glue at the connection of the water collection cloth 1 and the conduit 6, heat it to make the thermoplastic glue fuse, and bond the water collection cloth 1 to the outer wall of the conduit 6 to enhance the sealing between the water collection cloth 1 and the conduit 6 and prevent rainwater from leaking along the outer wall of the conduit 6, affecting rainwater collection. Then use iron wire to wind around the outside of the water collection cloth 1 to further strengthen the firmness between the water collection cloth 1 and the conduit 6.

[0028] The length of the conduit 6 is coordinated with the length of the first keel 2. It is preferably selected to be 0.3 - 0.5 meters. The outer diameter of the conduit 6 should not be too large to avoid inconvenient carrying. The outer diameter is preferably selected to be 5 - 15 millimeters. The wall thickness of the conduit 6 should not be too large to avoid increasing the weight. It is recommended to take 1 - 2 millimeters; a hand-held handle 5 of the whole instrument is provided at the lowermost end of the conduit 6, and the material of the handle 5 is elastic plastic or latex material.

[0029] A number of locking grooves 3 are provided on the outer side wall of the conduit 6. The slip ring 7 is fixed on the conduit 6 through a locking member 4 and the locking grooves 3. The inner diameter of the slip ring 7 is larger than the outer diameter of the conduit 6, and the slip ring 7 is sleeved on the conduit 6.

[0030] As Figure 5 shown, the locking member 4 includes a locking rod 401, a hinge ring 402, and a spring 403. The locking rod 401 passes through the slip ring 7. The locking rod 401 includes a pressing end 4011 and a locking end 4012. The pressing end 4011 is located outside the slip ring 7, and the locking end 4012 is arranged corresponding to the locking groove 3. The middle of the locking rod 401 is hinged to the slip ring 7 through the hinge ring 402. The hinge ring 402 is arranged on the inner side wall of the slip ring 7. One end of the spring 403 is fixed on the inner side wall of the slip ring 7, and the other end is fixed on the locking end 4012.

[0031] When force is applied to the pressing end 4011, the locking end 4012 rotates away from the locking groove 3 under the action of the hinge ring 402, thereby squeezing the spring 403, and the locking end 4012 moves away from the locking groove 3, releasing the fixation of the slip ring 7, pulling the slip ring 7 downward, so that the slip ring 7 slides downward along the guide tube 6, driving the second keel 10 and the first keel 2 to open, and the water collecting cloth 1 is opened into an inverted cone shape. When the slip ring 7 moves to the locking groove 3 at the lower end, the pressing end 4011 is released, and the locking end 4012 rotates toward the locking groove 3 under the action of the spring 403, so that the locking end 4012 is inserted into the locking groove 3, thereby fixing the slip ring 7. At this time, the water collecting cloth 1 is The sliding ring 7 is in an open state, and is kept in a stable open state under the support of the sliding ring 7, the first keel 2 and the second keel 10, so as to collect rainwater; when the collection is completed, the pressing end 4011 is applied with force again, and the locking end 4012 is away from the locking groove 3, so as to release the fixation of the sliding ring 7, push the sliding ring 7 upward, and as the sliding ring 7 moves upward along the conduit 6, the second keel 10 and the first keel 2 gradually show a tendency to close together, and when they move to the uppermost locking groove 3, the pressing end 4011 is released, and the locking end 4012 is inserted into the uppermost locking groove 3 to fix the sliding ring 7. At this time, the second keel 10 and the first keel 2 are gathered together, and the water-collecting cloth 1 is in a folded state, and then the binding belt 12 can be used to fix it (such as Figure 3 shown).

[0032] When collecting rainwater samples, hold the handle 5 under the conduit 6 in the open state with one hand, and hold the open sampling bottle with the other hand and place it directly under the conduit 6 (such as Figure 4 As shown), when rainwater flows out of the initial sampling conduit 6, do not use the sampling bottle to catch it first, so that part of the initial water flows away, so that the rainwater naturally rinses the water-collecting cloth 1 and the conduit 6. The rinsing can be basically completed by continuing to discharge water for 10 seconds, and then start to use the sampling bottle to catch the subsequent water out of the conduit 6. When the water sample in the sampling bottle meets the requirements, take out the sampling bottle and seal it; after the sampling is completed, organize and store the instrument, and then turn the instrument upside down with the opening of the water collection surface facing downward, and use gravity to make the water hanging on the wall of the water collection cloth 1 escape, or hold the instrument to dry, if conditions permit, do not fold it and then fold it after drying, and then fix the water collection cloth 1 with the strap 12, and the instrument is stored.

[0033] The dimensions of the device after folding are as follows: the length does not exceed 1 meter, the width does not exceed 4 centimeters, and the weight does not exceed 1.5 kilograms. If the support is made of lighter aviation aluminum, the weight is even less than 1 kilogram. Compared with most existing instruments with a length exceeding 1 meter, a width exceeding 0.5 meter, and a weight of at least 3 kilograms, this device significantly occupies less space, is lighter in weight, and has high portability, making it highly suitable for on-site rainwater collection. Moreover, this device is easy to operate. From taking out the instrument to completing the sampling, for ordinary rain types, a sampling can be completed within 5 minutes. Compared with existing instruments that require relatively cumbersome and time-consuming procedures such as instrument installation, power-on testing, opening the rain shield, and implementing sampling, this device features simple procedures and high efficiency in use.
