Description

Technical Field

[0001] This application relates to the field of emergency drought relief technology, specifically to a mobile emergency drought relief water storage bag. Background Technology

[0002] In agricultural production and ensuring people's livelihoods in arid regions, water storage is a core element in coping with seasonal droughts and sudden water shortages. Currently, drought relief water storage solutions widely employ fixed, immovable reservoirs to intercept rainwater, surface runoff, or store water transported from external sources, achieving centralized water storage. To accommodate the scattered and dispersed water demands of agricultural production, water users rely on portable water bags for self-collection and transportation.

[0003] Existing water bags typically have a detachable cap at the inlet, which can be screwed on for sealing or unscrewed for removal. Users remove the cap to open the inlet when collecting water, and then reseal the inlet before transporting the water to prevent the water bag from being jostled and causing water to overflow during transport.

[0004] However, in actual use, existing water bags often result in situations where personnel forget to replace the caps after taking water or load the bags directly onto vehicles without checking the inlet. When this happens, personnel are in the driver's seat, not in the storage compartment of the transport vehicle, and cannot observe the water bags in real time as they would during water collection operations. This makes it difficult to detect leaks promptly, and the inlet remains open, continuously overflowing water without being observed or remedied, leading to a waste of water resources during drought periods. Utility Model Content

[0005] Therefore, this application provides a mobile emergency drought relief water storage bag to solve the problem of existing water bags being easily forgotten to re-seale the water inlet, resulting in water waste.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A mobile emergency drought relief water storage bag, comprising:

[0008] The bag body has an inlet and an outlet. The inlet is equipped with a one-way valve, and the outlet is equipped with a controller for switching the on / off state of the outlet. The bag body has a pull rope, and the two ends of the pull rope are respectively connected to the inner walls of opposite ends of the bag body.

[0009] An explosion-proof net is used to enclose the bag body within the containment space formed by the explosion-proof net.

[0010] Optionally, the one-way valve is a right-angle one-way shut-off valve.

[0011] Further optionally, the right-angle one-way shut-off valve is a spring-loaded one-way valve, comprising:

[0012] The valve body is T-shaped and tubular. The two ends of the T-shape are respectively provided with an inlet and an outlet. The inlet is used to connect with the outlet of the active water supply equipment, and the outlet is sealed to the inlet of the bag body.

[0013] First spring;

[0014] A valve disc is mounted at one end to the inner wall of the T-shaped third end sealing tube of the valve body via a first spring. The extension and retraction direction of the first spring is consistent with the inlet water inlet axis of the valve body. A valve cover is connected to the end of the valve disc away from the first spring to seal the inlet of the valve body. The valve cover moves back and forth with the valve disc, moving closer to or away from a preset position that seals the inlet of the valve body in its movement trajectory.

[0015] Alternatively, the valve disc is connected to the valve cover via a second spring, the extension and retraction directions of the second spring and the first spring being the same.

[0016] Optionally, the inner wall of the valve body opposite to its inlet is provided with a first guide cylinder, the axial direction of the first guide cylinder is consistent with the inlet water inlet axis of the valve body, one end of the valve disc is located inside the cylinder and is installed on the inner wall of the first guide cylinder by a first spring, and the other end passes through the axial opening of the first guide cylinder to exit the cylinder.

[0017] Optionally, the outer wall of the bag is provided with a connecting part, the two ends of the connecting part are fixedly connected to the outer wall of the bag, and a gap is provided between the middle part of the connecting part and the bag body.

[0018] Compared to existing technologies, this application's embodiment features a one-way valve at the water inlet of the bag to automatically allow forward water flow and prevent reverse overflow. Therefore, after using the water bag to collect water and before transportation, personnel do not need to manually operate the inlet, avoiding situations where personnel forget to perform steps, leaks are not easily detected before transportation, or leaks are difficult to detect during transport due to the inability to observe the water bag's condition, leading to continuous overflow and wasted water resources.

Detailed Implementation

[0037] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0039] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0040] like Figure 1 As shown, this application provides a mobile emergency drought relief water storage bag, including a bag body 100 and an explosion-proof net 200. Wherein:

[0041] The water bag 100 has an inlet 110 and an outlet 120. The inlet 110 is equipped with a one-way valve, and the outlet 120 is equipped with a controller. This controller is used to switch the on / off state of the outlet 120. The controller can be a sealing component that is detachably connected to the outlet, such as a threaded second cap. When water is needed, the second cap is removed, changing the outlet state from "off" (water passage blocked, no water output) to "on" (water passage unobstructed, water can flow), facilitating water dispensing. Regarding the power for water dispensing from the water bag, a water pump or other equipment can be added to the water bag for active water supply, or a water pump or other driving device on the water-using equipment can be used. Alternatively, the orientation of the water bag can be simply adjusted. Figure 1As shown, the water outlet 120 is positioned as close to the ground as possible on the side of the bag 100, using the water pressure generated by the water stored inside the bag to drive the water flow. After each use, the second cap is installed to seal the water outlet 120, changing its state from "open" to "closed". Besides the aforementioned detachable sealing device controller, a valve controller can also be used. A second valve can be installed at the water outlet as a controller, and the on / off state of the water outlet 120 can be switched by adjusting the opening degree of the second valve. The bag 100 contains a pull rope 160, with both ends of the pull rope 160 connected to the inner walls of opposite ends of the bag 100.

[0042] The explosion-proof net 200 and the bag body 100 are installed within the containment space enclosed by the explosion-proof net 200.

[0043] In current water bag usage, some bags are filled with water directly while loaded onto the vehicle, requiring no movement before transport, making leaks undetectable by handling. Even when moving the bags for loading, manual handling is faster and more stable than vehicle transport, and the bags may not be fully filled in a single trip. Even if the cap is missing and the inlet is open, overflow is unlikely. Even if water does overflow, the amount during short, stable handling is minimal and difficult to detect in a short period. However, the prolonged bumps and jolting during vehicle transport lead to larger overflows per trip and more frequent overflows over longer transport times, ultimately resulting in significant water waste.

[0044] In this embodiment, a one-way valve is installed at the water inlet 110 of the bag body 100, which can automatically enable forward water inflow and stop reverse overflow. Therefore, after taking water from the water bag and before transportation, personnel do not need to manually close the water inlet 110. The one-way valve automatically achieves reverse flow control, effectively avoiding the problem of water wasting resources due to personnel forgetting to manually close the valve, or difficulty in detecting leaks during handling and transportation, which ultimately leads to the water inlet 110 remaining open and continuously overflowing.

[0045] This application incorporates a normally closed second valve at the water outlet 120 of the water bag 100. No operation is required during water collection and transportation; operation is only necessary when water is used, reducing reliance on manual operation and thus mitigating the risk of waste due to missed steps. Even if the valve is forgotten to be closed after the last use, water will flow out immediately upon collection. Since the person collecting water is next to the water bag, they can directly observe the water flow and take timely remedial action. If the second valve is not closed, water will continue to flow, providing a continuous reminder. These design features effectively remind users to take timely remedial action, reducing water waste.

[0046] In addition, during the transportation of water bags, stress tends to concentrate at structural defects in the bag body 100 due to factors such as aging of the bag body material, liquid vaporization and thermal expansion caused by long-term high-temperature transportation environment, and impact force generated by bumps, ultimately leading to water bag explosion.

[0047] In one possible implementation, the check valve is a right-angle check valve, and preferably a spring-loaded check valve. Specifically, the check valve includes a valve body 310, a first spring 330, and a valve disc 340.

[0048] The valve body 310 is T-shaped, with an inlet 315 and an outlet 317 at the two right-angled ends of the T-shape. The inlet 315 connects to the outlet of the active water supply device. Water enters the valve body 310 through the inlet 315 with a certain initial velocity, and the driving force for the water flow is provided by the active water supply device. Here, the active water supply device refers to drought-resistant water storage equipment, such as the aforementioned reservoir. As is well known, the function of drought-resistant water storage equipment is to store water during normal times and to supply water during droughts; therefore, it is necessary to install an active water supply actuator (water pump, etc.) or other alternative structure, which is a conventional setup in this field and will not be elaborated here. The outlet 317 is sealed and connected to the inlet 110 of the bag body 100.

[0049] One end of the valve disc 340 is installed on the inner wall of the T-shaped third end of the valve body 310 via the first spring 330. The extension and retraction direction of the first spring 330 is consistent with the water inlet axis of the valve body 310 inlet 315. The end of the valve disc 340 away from the first spring 330 is connected to a valve cover 360, which is used to seal the inlet 315 of the valve body 310. The valve cover 360 moves back and forth with the valve disc 340, approaching or moving away from the preset position of sealing the inlet 315 of the valve body 310 in its movement trajectory.

[0050] Optionally, the one-way valve also includes a second spring 350. The valve disc 340 is connected to the valve cover 360 via the second spring 350, and the extension and retraction directions of the second spring 350 and the first spring 330 are the same.

[0051] In one possible implementation, the valve body 310 is T-shaped, with three ends. One end is the first end, with an inlet 315. The other end is the second end, with an outlet 317. The first and second ends are perpendicular, and the inlet axis of the valve body 310 (inlet 315) and the outlet axis of the valve body 310 (outlet 317) are perpendicular, which is an inherent structural feature of a right-angle one-way shut-off valve and will not be elaborated here. The remaining end is the third end, which is sealed and closed without an opening. The third end and the first end are positioned opposite each other along the inlet axis of the valve body 310 (inlet 315), therefore, the third end of the valve body 310 can also be described as the end of the valve body 310 facing away from its inlet 315. This is also an inherent structural feature of a right-angle one-way shut-off valve and will not be elaborated here.

[0052] A first guide cylinder 320 is provided on the inner wall of the third end of the valve body 310. One axial end of the first guide cylinder 320 is fixed to the inner wall of the third end of the valve body 310, and the other axial end has a cylinder opening. The axial direction of the first guide cylinder 320 is consistent with the water inlet axial direction of the valve body 310 inlet 315. One end of the valve disc 340 along its own reciprocating motion direction is located inside the cylinder of the first guide cylinder 320, and is installed on the inner wall of the axial end of the first guide cylinder 320 opposite to its opening by a first spring 330. The other end of the valve disc 340 passes through the axial opening of the first guide cylinder 320 and extends out of the cylinder to connect with the valve cover 360.

[0053] Optionally, a second guide cylinder 361 is provided on the side of the valve cover 360 facing the valve disc 340. The axial direction of the second guide cylinder 361 is consistent with the water inlet axis of the valve body 310 inlet 315. The opposite ends of the valve disc 340 are located inside the first guide cylinder 320 and the second guide cylinder 361, respectively, and are fixed to the inner wall of the valve body 310 and the side wall of the valve cover 360 by the first spring 330 and the second spring 350, respectively. This application uses a cylindrical member extending along the water inlet axis of the valve body 310 inlet 315 to constrain the extension and retraction direction of the first spring 330 and the second spring 350, and the reciprocating motion direction of the valve disc 340, thereby preventing radial deviation.

[0054] In one possible implementation, the valve body 310 has a tubular end with an inlet 315 and a threaded or flanged 370 for connection with the output end of the active water supply device. The valve body 310 also has a tubular end with an outlet 317 and a threaded or flanged 370. The inlet 110 of the bag body 100 has a matching threaded or flanged 370, and the two are sealed together to achieve a sealed connection between the valve body 310 and the internal space of the water bag 100. A ring buckle 150 is welded to the inner wall of the bag as a ring-shaped fixing element for binding and securing the two ends of the pull rope 160. The pull rope 160 is pre-tightened, with one end passing through the annular opening of the ring buckle 150, going around the ring buckle 150, folding it in half, and securing it to the rope. The other end is fixed in the same way. Regarding the explosion-proof net 200, it can be an integral explosion-proof net 200 forming a three-dimensional accommodating cavity that matches the water-filled bag body 100, or it can be multiple planar meshes spliced ​​together to surround the outside of the bag body 100. Figure 5 , Figure 6 The embodiment shown is covered by a ring-shaped mesh structure. Figure 1The front, top, back, and bottom surfaces of the bag 100 in this embodiment are designed so that the left and right sides of the front are spliced ​​to fit the length of the front and back surfaces of the bag 100. The left and right sides are formed by splicing two mesh structures together to create a planar mesh, which is then spliced ​​to the edge of a ring-shaped mesh structure at the side edges, thus forming a whole explosion-proof net 200 for accommodating a rectangular water bag. The joints of multiple mesh structures are wrapped with flexible rope structures 210. The ends of the wrapping of the ring-shaped splices are joined together and fixed in pairs. At the joints of the side panel mesh structures, the ends of the wrapping of the flexible rope structures 210 are simply bound to any one of the mesh ropes. Regarding how the connecting part 140 and valves at the splicing point extend out of the explosion-proof net 200, they can be accommodated when selecting the explosion-proof net 200. If there are many of them and it is difficult to accommodate them all, the net ropes in the part covered by the net structure can be appropriately pulled and deformed. If the deformation exceeds the deformation capacity of the net ropes, an opening is made at this point to expose the parts. A ring rope is added to the edge of the opening to reinforce and bind the end of the net rope formed by the cut edge. This is a routine operation for accommodating the net structure, and this application will not elaborate on it.

[0055] In one possible implementation, the bag body 100 is also provided with a pressure relief port, which is equipped with a pressure relief valve 131 for venting and releasing pressure, thus extending service life and providing explosion-proof effects. The bag body 100 is made of soft, flexible polymer fabric, which can be a material produced by high-temperature heat sealing process, such as polyvinyl chloride coated fabric or waterproof fabric. The former is preferred. High-strength PVC coating technology is used to improve the softness of the bag body 100 material, making it easy to install and move. When not filled with water, it can also be folded to reduce the space occupied.

[0056] Optionally, when filled with water, the water bag unfolds into a rectangular structure of 2m*2m*1.2m. The pressure relief port and water inlet 110 are located on the top side of the rectangular structure. The water outlet 120 is located on the side of the rectangular structure. Eight 2-inch water outlets 120 are installed on the vertical side of the bag body 100 near the bottom (e.g., 50mm from the bottom). The water outlets 120 function as 2-inch ball valves as a second valve to control the water flow rate and volume. Alternatively, the mobile emergency drought-resistant water storage bag includes two or more bag bodies 100, connected end-to-end (water inlet 110) and end-to-end (water outlet 120) of the two or more bag bodies 100. The water outlet 120 of the bag body 100 can be connected in series with other water bags via a connecting pipe. At least one second valve is installed at the water outlet 120 of the last bag body 100.

[0057] In one possible implementation, the outer wall of the bag body 100 is provided with a connecting portion 140. Both ends of the connecting portion 140 are fixedly connected to the outer wall of the bag body 100, and a gap is provided between the middle of the connecting portion 140 and the bag body 100. A closed loop for hoisting and holding is formed in the middle, fixing the bag body 100 to a hook in the transport vehicle, preventing the bag body 100 from moving and tipping over during bumpy rides, thus avoiding collisions that could lead to explosions or leaks due to punctures by sharp objects. The explosion-proof net 200 uses mesh to make way for the connecting portion 140, or the connecting portion 140 is made of flexible material, passing through a nearby mesh and fixed to the vehicle hook. Preferably, the outer wall of the water bag is provided with two or more connecting portions 140, increasing connection stability through multiple connections. The position of the connecting portion 140 can be arbitrarily set to increase stability. Alternatively, several connecting portions 140 can be grouped together, with several connecting portions 140 in a group distributed circumferentially around the height axis of the bag body 100 to improve connection stability. The mobile emergency drought relief water storage bag is equipped with multiple sets of connecting parts 140, which are distributed adjacently along the height direction of the bag body 100. Regarding the height direction of the bag body 100, the bag body 100 has a three-dimensional structure when unfolded, with three axes that are perpendicular to each other and all pass through the center of gravity. When hanging the water bag, one of these axes is distributed along the direction of gravity, and this axis is the axis of the bag body 100 along the height direction.

[0058] In one possible implementation, the connecting part 140 is a folded nylon rope with both ends welded to the outer wall of the bag body 100. The folding inflection point in the middle separates from the bag body 100 to form a gap. The bag body 100 and the nylon rope form a closed loop, which is used to hang the water bag in the vehicle, keep it relatively stationary, and reduce a series of risks caused by random displacement.

[0059] In one possible implementation, the valve body 310 has a third opening and a third cover 311 at its third end. The third cover 311 is used for a sealed connection with the third opening of the valve body 310 (e.g., a detachable connection via bolts 313, facilitating disassembly, maintenance, replacement, and reinstallation of components). The third cover 311, connected to the valve body 310, seals and closes the third opening (a third sealing ring 312 is provided on the contact surface; the elastic material of the third sealing ring 312 elastically expands and contracts to fill the gaps in the contact area, improving the sealing degree). First, the valve disc 340, the first spring 330, the first guide cylinder 320, etc., are installed on one side of the third cover 311. Then, these components are inserted into the valve body 310 through the third opening and subsequently sealed. If the spring fails or other components malfunction, the third cover 311 can be removed from the third opening, and the valve body 310 can be taken out for replacement and maintenance, expanding the operating space and reducing the difficulty of operation.

[0060] Optionally, the first spring 330 and the like are distributed on one side of the third cover 311. After the third cover 311 is installed on the third opening, it exists as the inner wall of the end of the valve body 310 opposite to its inlet 315. A clamping protrusion is provided on the opposite side of the third cover 311. The third cover 311 is clamped by a wrench, pliers, etc. to fix the third cover 311, which facilitates gripping, positioning, alignment, and installation after alignment. The first guide cylinder 320 is fixed to the third cover 311 by screws 314.

[0061] In one possible implementation, the stiffness of the first spring 330 is greater than that of the second spring 350. This application ensures the low-pressure sensitivity of the check valve by setting the second spring 350. Even if the inlet water pressure at inlet 315 is low, the second spring 350 can still have sufficient expansion and contraction, allowing the valve cover 360 to retract away from inlet 315 and allowing water flow. If the inlet water pressure at inlet 315 is too high, both springs will contract under pressure, causing the valve disc 340 to retract away from inlet 315. The first spring 330, with its greater stiffness, can absorb more mechanical energy within the same expansion and contraction range, even with a fixed installation space and limited expansion and contraction. This high energy storage characteristic effectively buffers the impact of high-pressure water flow, preventing local pressure from exceeding the elastic limits of the two springs or other structural bearing limits due to sudden increases in water pressure, thereby preventing component damage and ensuring the stable operation of the valve as a whole.

[0062] In one possible implementation, the two opposite ends of the valve disc 340 extend and retract within the first guide cylinder 320 and the second guide cylinder 361, respectively. A first sealing ring 321 is provided at one end of the valve disc 340 or on the inner wall of the axial opening of the first guide cylinder 320, and a second sealing ring 351 is provided at the other end of the valve disc 340 or on the inner wall of the axial opening of the second guide cylinder 361. The extension and retraction of the elastic material of the sealing ring ensures that there is a movable gap between the radial outer edge of the valve disc 340 and the inner wall of the cylinder, and that they are tightly fitted and sealed in a static state, preventing water from seeping into the cylinder and contacting the spring metal parts, thus corroding the spring and shortening its service life. The sealing fit of the sealing ring allows the valve disc 340 to reciprocate, and also allows the exchange of highly permeable gas required for its reciprocating motion. This is the inherent structure and basic function of the sealing ring sealing the extension and retraction cavity, which will not be elaborated here. Preferably, when the valve cover 360 is located at a preset position at the inlet 315 of its sealing valve body 310, 0 < the compression of the spring with the minimum stiffness < its maximum compression. In other words: if the check valve only has a first spring 330 and no second spring 350, and the valve cover 360 is located in the preset position sealing the inlet 315 of the valve body 310, then 0 < the compression amount of the first spring 330 < the maximum compression amount of the first spring 330. If the check valve has a second spring 350, then when the valve cover 360 is located in the preset position sealing the inlet 315 of the valve body 310, then 0 < the compression amount of the second spring 350 < the maximum compression amount of the second spring 350.

[0063] In one possible implementation, the valve body 310 has an inlet 315 at one end of the pipe forming a Venturi channel 316 within the pipe. The Venturi channel 316 refers to the pipe wall smoothly contracting and then expanding inwards along the water inlet 315 of the valve body 310. The fluid accelerates in the contraction section, converting pressure energy into kinetic energy, resulting in a smaller pressure difference before and after the valve disc 340, further reducing flow resistance. The negative pressure effect generated in the expansion section helps to push the valve disc 340 to the closed position more quickly during the initial pump shutdown, reducing backflow.

[0064] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0065] The present application has been described in a relatively specific and detailed manner above through general descriptions and specific embodiments.
