Description

Technical Field

[0001] This utility model relates to the field of emergency water supply technology, and in particular to a portable emergency water supply device. Background Technology

[0002] In emergency scenarios such as natural disasters (e.g., earthquakes, floods, mudslides), public health emergencies, or water shortages in remote areas, emergency water supply devices are key equipment for ensuring people's basic drinking water needs. Their ease of use and response efficiency are directly related to the effectiveness of rescue work.

[0003] While some existing emergency water supply devices are equipped with movable parts, the braking mechanism of the movable wheels is mostly a single brake pad type, and the linkage between the braking component and the wheel axle is poor. During water supply operations, the device needs to remain stationary to ensure stable water pumping and normal filtration of the filter element. However, if there is slight vibration on the ground or accidental contact by personnel, the movable wheels with a single brake are prone to "slipping". Displacement of the device will not only cause the inlet pipe to detach from the water source and the outlet pipe to fall off, interrupting the water supply process, but may also damage the movable wheels due to collision with surrounding objects, further losing the ability to move, creating new obstacles for subsequent transportation, and seriously affecting the continuity of emergency water supply. Therefore, we propose a portable emergency water supply device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a portable emergency water supply device. This device addresses the issue that while some existing emergency water supply devices are equipped with moving parts, the braking mechanism of the moving wheels is mostly a single brake pad type, and the linkage between the braking component and the wheel axle is poor. During water supply operations, the device needs to remain stationary to ensure stable water pumping and normal filtration of the filter element. However, if there is slight vibration on the ground or accidental contact by personnel, the single-brake moving wheels are prone to "slipping." Displacement of the device can not only cause the inlet pipe to detach from the water source and the outlet pipe to fall off, interrupting the water supply process, but may also damage the moving wheels due to collisions with surrounding objects, further losing its mobility and creating new obstacles for subsequent transportation, seriously affecting the continuity of emergency water supply. Therefore, we propose a portable emergency water supply device to solve this problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable emergency water supply device, comprising: A fixed base, with a water pump fixedly installed inside the fixed base; A movable adjustment structure is located on a fixed base; The movable adjustment structure includes two fixed plates, a support shaft, two mounting seats, and a positioning square plate. The two fixed plates are fixedly connected to both sides of the fixed base, and the support shaft is rotatably connected to the opposite surfaces of the two fixed plates. Both mounting seats are fixedly sleeved on the outer surface of the support shaft, and two movable wheels are fixedly installed on each of the two mounting seats. The positioning square plate is fixedly sleeved on the outer surface of the support shaft, and mounting grooves and threaded holes are respectively opened on both sides of the positioning square plate.

[0006] Preferably, the movable adjustment structure further includes a connecting plate, a locking bolt, a blocking block, and a mounting slide plate. The mounting slide plate is slidably connected inside the corresponding mounting groove. The blocking block is fixedly connected to the side of the mounting slide plate away from the positioning square plate. The side of the blocking block away from the mounting slide plate is in contact with the outside of the fixed base. The connecting plate is fixedly connected to the top of the blocking block and the mounting slide plate. The top of the connecting plate has a through hole. The locking bolt passes through the inside of the through hole and is threadedly connected to the inside of the corresponding threaded hole.

[0007] Preferably, there are two movable adjustment structures, which are symmetrically arranged on both sides of the fixed base.

[0008] Preferably, magnetic attracting pieces 1 are embedded in both sides of the fixed base, and magnetic attracting pieces 2 are embedded in the side of the two blocking blocks near the fixed base. The two magnetic attracting pieces 2 are attracted to the corresponding magnetic attracting pieces 1.

[0009] Preferably, both the mounting groove and the connecting plate are convex structures.

[0010] Preferably, the fixed base has a "U" shaped structure.

[0011] Preferably, the included angle between the two moving wheels is 90°.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This portable emergency water supply device, through two symmetrically arranged movable adjustment structures, combined with the linkage design of the support shaft, mounting base and movable wheels, allows the device to quickly switch to the movable state; and the two movable wheels are at a 90° angle, which not only ensures the directional controllability during the movement, but also, through the rigid constraint structure of locking bolts, connecting plates, mounting slide plates and blocking blocks, can firmly lock the support shaft to prevent the movable wheels from rotating accidentally during the water supply process, thereby improving the fixed stability of the device and ensuring the continuous and stable operation of the water pump.

[0019] Fixed base 1: The basic load-bearing structure of the device, which is U-shaped in general, provides a mounting base for the water pump 2, the two fixed plates 3 and the embedded magnetic suction plate 8. At the same time, during the transfer and adjustment of the device, the support shaft 4 is constrained and initially fixed by the contact with the blocking block 14 and the adsorption of the magnetic suction plate 8 and the magnetic suction plate 9. Water pump 2: Fixedly installed inside the fixed base 1, it is the core water supply component of the emergency water supply device, used to draw water and realize the emergency water supply function; Fixed plate 3: There are two plates, which are fixedly connected to both sides of the fixed base 1 respectively. They serve as the rotation support structure for the support shaft 4, providing a stable rotation fulcrum for the support shaft 4 and ensuring that the support shaft 4 can rotate smoothly around it. Support shaft 4: Rotatably connected to the opposite surfaces of the two fixed plates 3, it is the core transmission structure connecting the mounting base 5 and the positioning square plate 7. It can rotate around the fixed plate 3. When rotating, it can drive the mounting base 5 and the positioning square plate 7, which are fixedly sleeved on its outer surface, to rotate synchronously, thereby realizing the position adjustment of the moving wheel 6. Mounting base 5: There are two of them, both of which are fixedly sleeved on the outer surface of the support shaft 4. They are the mounting carriers for the movable wheel 6, used to fix the movable wheel 6 on the support shaft 4, so that when the support shaft 4 rotates, it can drive the movable wheel 6 to rotate synchronously, realizing the switching between the movable wheel 6 being in contact with or detached from the ground. Two movable wheels 6 are fixedly installed on each mounting base 5. The included angle between the two movable wheels 6 is 90°. When the support shaft 4 drives the mounting base 5 to rotate until the movable wheel 6 contacts the ground, one movable wheel 6 is used to support the device and assist the device in moving. The other movable wheel 6 is located on one side of it and plays a role in preventing tipping. The device can be easily transferred by rolling. Positioning square plate 7: It is fixedly sleeved on the outer surface of the support shaft 4. It has mounting grooves 16 and threaded holes 12 on both sides. It is the mounting positioning structure for mounting slide plate 15 and locking bolt 10 in the movable adjustment structure, providing a sliding track for mounting slide plate 15 and a threaded connection base for locking bolt 10. Magnetic plate 18: Embedded on both sides of the fixed base 1, it attracts each other with the magnetic plate 29 embedded in the blocking block 14. When the blocking block 14 moves down to fit against the outer surface of the fixed base 1, the position of the blocking block 14 is initially fixed to avoid accidental rotation of the support shaft 4. Magnetic suction piece 2 9: It is embedded in the side of the two blocking blocks 14 near the fixed base 1, and attracts the corresponding magnetic suction piece 1 8. It works with the magnetic suction piece 1 8 to achieve the initial fixation of the blocking block 14 and assist in constraining the rotation of the support shaft 4. Locking bolt 10: Passes through the through hole 13 at the top of the connecting plate 11 and is threadedly connected to the threaded hole 12 on the positioning square plate 7. It is a fixing component of the connecting plate 11. When loosened, it can release the fixing constraint of the connecting plate 11, making it easier for the connecting plate 11 to drive the related components to move. When tightened, it engages with the threaded hole 12 to firmly fix the connecting plate 11 on the positioning square plate 7, ultimately achieving complete locking of the support shaft 4. Connecting plate 11: It is convex in shape and is fixedly connected to the top of the blocking block 14 and the mounting plate 15. The top has a through hole 13, which is the structure connecting the blocking block 14 and the mounting plate 15. It also provides a passage for the locking bolt 10. During operation, it can drive the blocking block 14 and the mounting plate 15 to move up and down synchronously, so as to release and lock the rotation constraint of the support shaft 4. Threaded hole 12: It is opened on one side of the positioning square plate 7 and is threadedly connected to the locking bolt 10, providing a fixing base for the locking bolt 10. The locking bolt 10 can be fixed and loosened to the connecting plate 11 through thread engagement. Through hole 13: It is opened on the top of the connecting plate 11 for the locking bolt 10 to pass through, so that the locking bolt 10 can be connected to the threaded hole 12 on the positioning square plate 7, providing an installation channel for the locking bolt 10; Block 14: It is fixedly connected to the side of the mounting slide plate 15 away from the positioning square plate 7. The side close to the fixed base 1 has a magnetic suction piece 9 embedded in it. It is a key component for restricting the rotation of the support shaft 4. When it is in contact with the outer surface of the fixed base 1, it can restrict the rotation of the support shaft 4. When it is away from the outer surface of the fixed base 1, it releases the rotation constraint on the support shaft 4. The mounting slide 15 is slidably connected inside the mounting groove 16 corresponding to the positioning square plate 7, and is fixedly connected to the side of the blocking block 14 near the positioning square plate 7. Its top is fixed to the connecting plate 11. It is a sliding connection structure between the blocking block 14 and the positioning square plate 7. It can slide up and down along the mounting groove 16, driving the blocking block 14 to move synchronously, so as to achieve the contact or separation of the blocking block 14 and the fixed base 1.

[0020] Example 1: like Figure 1-4 As shown, after a natural disaster occurs in a mountainous area, it is necessary to quickly provide emergency water supply to the affected people. The fixed base 1 of this portable emergency water supply device is made of high-strength lightweight alloy material to reduce the overall weight and facilitate manual transport on rugged mountain roads. The moving wheels 6 in the movable adjustment structure are made of large-size, high-grip off-road tires to adapt to the complex terrain of the mountainous area.

[0021] When the device needs to be moved, the locking bolt 10 is unscrewed from the threaded hole 12. At this time, the mounting plate 15 can slide freely in the mounting groove 16, and the positioning square plate 7 can rotate around the support shaft 4, so that the moving wheel 6 contacts the ground. Utilizing the high friction and grip of the off-road tires, the device can be easily moved on the mountain road. After reaching the water supply point, the device is adjusted to a suitable position, and the locking bolt 10 is rotated in the opposite direction so that it passes through the through hole 13 and is threadedly connected to the threaded hole 12. The connecting plate 11 and the mounting plate 15 are fixed, thereby fixing the positioning square plate 7 and the moving wheel 6. This prevents the device from moving due to uneven ground during use, ensuring that the water pump 2 can work stably and provide continuous emergency water supply to the disaster-stricken people.

[0022] Example 2: like Figure 3-4 As shown, when the device is placed on a hard surface around the building, due to the complex on-site environment, there may be situations such as people walking around and vibrations caused by the operation of fire-fighting equipment. At this time, magnetic plate 18 is embedded in both sides of the fixed base 1, and magnetic plate 29 is embedded in the two blocking blocks 14 on the side near the fixed base 1. After the device is adjusted to the correct position by the moving adjustment structure and initially fixed by the locking bolt 10, magnetic plate 18 and magnetic plate 29 attract each other and generate a strong adsorption force.

[0023] This adsorption force can effectively resist external vibrations and minor collisions, preventing the device from affecting the normal operation of the water pump 2 due to shaking during use, ensuring a continuous and stable water source for fire fighting in high-rise buildings, and improving rescue efficiency.

[0024] Furthermore, when using this device, if it is necessary to transfer the device to the emergency water supply site, first loosen the locking bolt 10 in the movable adjustment structure: Since the locking bolt 10 passes through the through hole 13 at the top of the connecting plate 11 and is threadedly connected to the threaded hole 12 on the positioning square plate 7, after loosening, the fixed constraint of the connecting plate 11 is released. At this time, since the mounting slide plate 15 and the "convex" shaped mounting groove 16 on the positioning square plate 7 are in sliding fit, the connecting plate 11 can be pushed upward, causing the mounting slide plate 15 to move upward along the mounting groove 16, thereby causing the blocking block 14, which is fixedly connected to the mounting slide plate 15, to move upward synchronously until the blocking block 14 moves away from the outer surface of the fixed base 1, releasing the rotation constraint on the support shaft 4.

[0025] Subsequently, the support shaft 4 is rotated with the two fixed plates 3 as fulcrums. Since the support shaft 4 is rotatably connected to the opposite surfaces of the two fixed plates 3, and the two mounting seats 5 are fixedly sleeved on the outer surface of the support shaft 4, the mounting seats 5 will rotate synchronously with the support shaft 4 during the rotation. Eventually, the two movable wheels 6 fixed on the mounting seats 5 will contact the ground, so that one of the movable wheels 6 is used for support and movement, and the other movable wheel 6 is located on one side of the movable wheel to prevent tipping. At this time, the fixed base 1 is supported by the movable wheel 6, and the operator can push the device to achieve convenient transfer of the device by the rolling of the movable wheel 6.

[0026] After adjustment, pull down the connecting plate 11 to move the mounting slide plate 15 down along the rotated "convex" mounting groove 16 until the side of the blocking block 14 close to the fixed base 1 is in contact with the outer surface of the fixed base 1. At this time, the magnetic absorbing piece 9 embedded in the blocking block 14 and the magnetic absorbing piece 8 embedded on both sides of the fixed base 1 attract each other, initially fixing the position of the blocking block 14 and preventing the support shaft 4 from rotating accidentally.

[0027] Finally, tighten the locking bolt 10. By engaging the threads of the locking bolt 10 with the threaded hole 12, the connecting plate 11 is firmly fixed to the positioning square plate 7. Since the connecting plate 11 is fixedly connected to the mounting slide plate 15 and the blocking block 14, the support shaft 4 is completely locked, ensuring that the moving wheel 6 no longer rotates and the device enters a stable and fixed state.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
