Description

Technical Field

[0001] The present invention relates to the field of energy conservation and environmental protection, and in particular to a glacier water acquisition device. Background Art

[0002] Glacial water resources are solid bodies of water stored in the form of glaciers on Earth. Glacial water is produced by the melting of glaciers. Due to the addition of precipitation, groundwater, snowmelt, and other sources, the glacial water content decreases the further away from the glacier the water source is from. For example, for some glaciers, over the past 60 years, measurements at a distance of 200 meters from the glacier showed that glacial runoff accounted for approximately 70% of the total runoff. Of this 70%, precipitation within the glacier area accounted for 44%, while meltwater, or runoff from glacial ice melt, accounted for only 26%. This poses a challenge to obtaining high-purity glacial water, necessitating proximity to the glacier to obtain high-quality glacial water. However, the vast majority of glaciers are important solid water resources, and harvesting ice from glaciers to obtain glacial water is prohibited.

[0003] The inventors discovered during their research that the existing methods for obtaining glacial water have at least the following disadvantages:

[0004] The purity of the glacier water obtained is lower. Summary of the Invention

Because the glacier water is collected in the ice cave, the glacier water in the ice cave has a high purity.

DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] Currently, obtaining high-purity glacier water typically involves driving a water truck or other means of transportation to the glacier, using pumps and other equipment to extract the water on-site, and then transporting the water to a designated location for treatment before use. This process is labor-intensive and energy-intensive, and is significantly affected by environmental factors, making continuous water extraction impossible. Furthermore, to ensure safety and to avoid damaging the ecological environment of the glacier area, water extraction is carried out at a distance from the glacier, resulting in lower purity raw water.

[0034] In view of this, the designer provides a glacier water acquisition device, which can reduce labor intensity, reduce energy consumption, save energy, and improve the purity of the collected glacier water.

[0035] Please combine Figure 1-Figure 3 In this embodiment, the glacier water acquisition device includes a raw water collector 100, a first water reservoir 200, a filtration and sterilization unit, and a second water reservoir 600. The raw water collector 100 is placed in the ice cave; the first water reservoir 200 is connected to the raw water collector 100, the filtration and sterilization unit is connected to the first water reservoir 200, and the second water reservoir 600 is connected to the filtration and sterilization unit. The heights of the raw water collector 100, the first water reservoir 200, the filtration and sterilization unit, and the second water reservoir 600 are arranged in descending order.

[0036] Based on the above, the working principle of the glacier water acquisition device provided in this embodiment is as follows:

[0037] During operation, the raw water collector 100 is first placed in an ice cave formed by long-term erosion of glacial meltwater. The glacial water collected by the raw water collector 100 is then transported to the first reservoir 200. It then passes through a filtration and sterilization unit and is stored in the second reservoir 600. The glacial water in the second reservoir 600 is then transferred as needed, allowing the glacial water to be used in different scenarios and improving its utilization rate. Because the glacial water is collected within the ice cave, it has a higher purity. Furthermore, during the transportation process, after passing through the filtration and sterilization unit, solid impurities, bacteria, and viruses carried in the glacial water are eliminated, improving the water quality and facilitating subsequent direct use. During the glacial water transportation process, the heights of the raw water collector 100, the first reservoir 200, the filtration and sterilization unit, and the second reservoir 600 are successively lowered. This allows the glacial water to flow from the raw water collector 100 through the first reservoir 200, the filtration and sterilization unit, and the second reservoir 600 by gravity, reducing energy consumption during the glacial water transportation process and promoting energy conservation and environmental protection.

[0038] The following examples illustrate the detailed structure of the glacier water acquisition device provided in this application.

[0039] Please combine Figure 1 In this embodiment, the glacier water acquisition device optionally includes a raw water collector 100, a first water reservoir 200, a first filtration and sterilization unit 300, a second filtration and sterilization unit 400, a third filtration and sterilization unit 500, and a second water reservoir 600. The raw water collector 100 is intended to be placed within the ice cave. The first water reservoir 200 is connected to the raw water collector 100, the first filtration and sterilization unit 300 is connected to the first water reservoir 200, the second filtration and sterilization unit 400 is connected to the first filtration and sterilization unit 300, the third filtration and sterilization unit 500 is connected to the second filtration and sterilization unit 400, and the second water reservoir 600 is connected to the third filtration and sterilization unit. The raw water collector 100, the first water reservoir 200, the first filtration and sterilization unit 300, the second filtration and sterilization unit 400, the third filtration and sterilization unit 500, and the second water reservoir 600 are connected to the third filtration and sterilization unit.

[0040] As described above, to collect raw water, the raw water collector 100 is placed in the ice cave and submerged in the water within. Once the water enters the raw water collector 100, it flows under gravity through the first water reservoir 200, the first filtration and sterilization unit 300, the second filtration and sterilization unit 400, the third filtration and sterilization unit 500, and the second water reservoir 600. The raw water is sterilized and disinfected as it passes through the first filtration and sterilization unit 300, the second filtration and sterilization unit 400, and the third filtration and sterilization unit 500. The glacial water stored in the second water reservoir 600 is of high purity and quality, making it easy to use. Because the glacial water is automatically transported by gravity, energy consumption and costs are low. The raw water collector 100 is placed in the ice cave and draws water directly from the ice cave, eliminating the need for multiple trips to the glacier, minimizing environmental impact, and enabling continuous water collection.

[0041] Please combine Figure 2 In this embodiment, the raw water collector 100 optionally includes a floating raft 110, a collection head 120, and a water pipe 130. The floating raft 110 is designed to float on the water surface 001 within the ice cave. The collection head 120 is mounted on the floating raft 110. One end of the water pipe 130 is connected to the collection head 120, and the other end of the water pipe 130 is connected to the first filtration and sterilization unit 300. Furthermore, the floating raft 110 is used to adjust the collection head 120 between an active position and an inactive position. When the collection head 120 is in the active position, raw water enters the collection head 120 and is transported to the first water reservoir 200 through the water pipe 130. When the collection head 120 is in the inactive position, the water pipe 130 stops transporting water.

[0042] It should be noted that glacier water is generally best collected from June to September each year. When all the snow on the glacier melts and the glacier enters its ablation period, the daytime temperature is high, the glacier melts rapidly, and the glacier meltwater contains high levels of inorganic and organic components, as well as a large amount of sediment. However, at night, the temperature drops, the glacier melt slows, and the inorganic, organic, and sediment contents decrease. Therefore, glacier water is generally collected at night, as the collected glacier water is of higher purity. The structural design of the floating raft 110 and the collection head 120 allows the state of the collection head 120 to be controlled. During the day, the collection head 120 can be placed in an inactive position, preventing glacier water from entering the collection head 120 and, therefore, not being collected. At night, by adjusting the state of the float 110, the collection head 120 is switched from the non-working position to the working position, and the collection head 120 is immersed in the raw water. Under the action of gravity, the glacial water enters the first water reservoir 200 from the collection head 120, and then flows from the first water reservoir 200 through the first filtration and sterilization unit 300, the second filtration and sterilization unit 400, and the third filtration and sterilization unit 500 in sequence. The filtered glacial water is stored in the second water reservoir 600.

[0043] Please combine Figure 2 and Figure 3 Optionally, the floating row 110 includes a bladder 111 and an annular partition 112. The bladder 111 is a circular ring structure, and the middle portion of the bladder 111 forms a circular collection hole 116. The interior of the bladder 111 is formed with an annular ring chamber. The annular partition 112 is disposed within the annular chamber, and the edge of the annular partition 112 is sealed to the inner wall of the bladder 111. The annular partition 112 separates the annular chamber into an annular inner cavity 113 and an annular outer cavity 114. Both the annular inner cavity 113 and the annular outer cavity 114 are annular chambers. The annular outer cavity 114 is located outside the annular inner cavity 113, which is located outside the collection hole 116. An air pump is installed on the floating row 110. The air pump can be installed on the surface corresponding to the annular outer cavity 114 without affecting the shape adjustment of the annular inner cavity 113. The air pump is connected to the annular inner cavity 113 and is used to adjust the air pressure in the annular inner cavity 113. In other words, the air pump can inflate the annular inner cavity 113, thereby increasing the air pressure in the annular inner cavity 113 and expanding the annular inner cavity 113 to support the collection head 120. At the same time, the air pump can also deflate the annular inner cavity 113, causing the annular inner cavity 113 to deform and weaken its supporting capacity.

[0044] Optionally, an air supply channel is provided on the annular spacer 112, and the annular inner cavity 113 is connected to the annular outer cavity 114 through the air supply channel. A one-way vent valve 115 is provided in the air supply channel, and the one-way vent valve 115 only allows gas to enter the annular outer cavity 114 from the annular inner cavity 113. When the annular inner cavity 113 is inflated, the gas can enter the annular outer cavity 114, thereby inflating the annular outer cavity 114.

[0045] Optionally, the collection head 120 has a connected water inlet 121 and a water outlet 122. The water inlet 121 is located within the area enclosed by the collection holes 116, and the water pipe 130 is connected to the water outlet 122. When in the operating position, the water inlet 121 is immersed in the raw water, and the height of the water outlet 122 is lower than the raw water surface 001, so that the raw water can be transported through the water pipe 130. To facilitate the installation of the collection head 120, the collection head 120 is provided with a counterweight plate 140. The counterweight plate 140 is a circular plate and overlaps the floating row 110. For example, the counterweight plate 140 is placed directly above the floating row 110 and is located within the area enclosed by the annular spacer 112. In other words, the counterweight plate 140 is supported by the annular inner cavity 113. When the air pressure in annular cavity 113 is high, the shape of annular cavity 113 is stable and resistant to deformation. The counterweight plate 140 is supported by annular cavity 113, and the height of the collection head 120 is spaced from the water surface 001. At this point, water cannot be transferred. When water transfer is required, the air in annular cavity 113 is deflated, reducing the air pressure and the supporting force. Under the action of its own weight, the counterweight plate 140 presses against the raft 110, causing it to descend, driving the collection head 120 downward. The collection head 120 is immersed in the water, and both the water inlet 121 and the water outlet 122 are submerged, achieving water transfer. In this way, by adjusting the air pressure in the raft 110, the position of the collection head 120 can be adjusted, thereby controlling the timing of raw water collection and obtaining raw water of higher purity.

[0046] It should be understood that the air pump can be remotely controlled or its operating time can be adjusted by setting a relay. This is not specifically limited in this embodiment, and it can be selected during the time period of raw water collection. In addition, the air pump can be equipped with a battery and can also be equipped with a photovoltaic panel to provide it with electricity.

[0047] In other embodiments, optionally, a first anti-detachment hook 150 is provided on the counterweight plate 140, and a second anti-detachment hook 160 is provided on the wall of the collection hole 116. The first anti-detachment hook 150 engages with the second anti-detachment hook 160, and the first anti-detachment hook 150 can rotate relative to the second anti-detachment hook 160. With such a design, when the annular inner cavity 113 is deflated to switch the collection head 120 to the working position, the mutual engagement of the first anti-detachment hook 150 and the second anti-detachment hook 160 can control the position of the counterweight plate 140, preventing the counterweight plate 140 from directly sliding off the floating row 110. When the annular inner cavity 113 is inflated, it is convenient to use the floating row 110 to lift the counterweight plate 140, thereby raising the height of the counterweight plate 140 and switching the collection head 120 to the non-working position.

[0048] In addition, a vent hole 141 communicating with the collection head 120 is provided on the counterweight plate 140 .

[0049] In this embodiment, optionally, the first filtering and sterilizing unit includes a first filter tube 310 and a first exposure pool 320. The second filtering and sterilizing unit includes a second filter tube 410 and a second exposure pool 420. The third filtering and sterilizing unit includes a third filter tube 510 and a third exposure pool 520. The first filter tube 310 is connected to the first water reservoir 200, and the first filter tube 310, the first exposure pool 320, the second filter tube 410, the second exposure pool 420, the third filter tube 510, and the third exposure pool 520 are connected in sequence, and the first filter tube 310, the second filter tube 410, and the third filter tube 510 are all set at an angle α to the horizontal plane, where α is an acute angle. The angles of the first filter tube 310, the second filter tube 410, and the third filter tube 510 with the horizontal plane increase successively. That is, the slopes of the first filter tube 310, the second filter tube 410, and the third filter tube 510 increase successively. At the beginning of raw water collection, the first filter tube 310 filters the raw water for the first time. The slope of the first filter tube 310 is small, the flow rate of the raw water is slow, and the raw water stays in the first filter tube 310 for a long time, resulting in a good filtering effect. Subsequently, the filtering requirements for the raw water are reduced. Therefore, when the raw water flows through the second filter tube 410 and the third filter tube 510, the slope gradually increases, the flow rate gradually accelerates, and the raw water transportation efficiency is improved.

[0050] It should be understood that the height of the upstream port of each filter tube is greater than the height of the downstream port, so that the raw water can flow automatically by gravity, reducing the energy consumption required for transportation.

[0051] Optionally, the first filter tube 310, the second filter tube 410, and the third filter tube 510 are all spiral tubes, which can extend the flow time of the raw water and improve the purification effect. The first filter tube 310, the second filter tube 410, and the third filter tube 510 are each provided with a filter layer for filtering the raw water. The filter layer can be clay and gravel collected from glaciers, and the clay and gravel can be arranged in layers.

[0052] Optionally, each exposure pool has a closed water storage chamber, and at least a portion of the exposure pool is configured as a light-transmitting structure. Thus, raw water flows through the water storage chamber, preventing the ingress of foreign matter and contamination of the raw water. Sunlight can penetrate the light-transmitting structure to illuminate the raw water, thereby achieving disinfection and sterilization.

[0053] The glacier water acquisition device provided in this embodiment relies on gravity to achieve the automatic flow of glacier water, with low energy consumption, low labor intensity and low cost; and can select the collection period of glacier water as needed, making collection flexible and convenient, and can improve the purity of the collected glacier water.

[0054] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
