Description

Technical Field

[0001] The utility model relates to the field of emergency rescue, in particular to a water supply and drainage vehicle and a drainage device thereof. Background Art

[0002] Water supply and drainage vehicles are crucial equipment in emergency rescue operations. They can quickly and efficiently transfer liquids from water sources to designated discharge points or disaster areas, playing an irreplaceable role in post-disaster reconstruction and water resource allocation in emergency situations. To meet diverse operational needs, existing water supply and drainage vehicles are typically equipped with a variety of piping systems to achieve flexible and efficient liquid transfer.

[0003] Referring to the applicant's previous patent (authorization announcement number: CN113350721B), a water intake system for a vehicle body is disclosed, comprising a base, a water pump, a water intake pipe, a connecting pipe and a first water pipe assembly; the water intake pipe and the first water pipe assembly are arranged side by side on the base, the water inlet end of the water intake pipe and the water outlet end of the first water pipe assembly are arranged on the same side, the water outlet end of the water intake pipe and the water inlet end of the first water pipe assembly are arranged on the same side, the water pump is set at the water inlet of the water intake pipe, the water outlet end of the water intake pipe is detachably connected to one end of the connecting pipe, the other end of the connecting pipe is detachably connected to the water inlet end of the first water pipe assembly, and the water outlet end of the first water pipe assembly is used to connect a water intake device or a water pipe.

[0004] In actual application, the above water intake system can adapt to two main working modes:

[0005] Mode 1: Install the connecting pipe between the water intake pipe and the first water pipe assembly, and discharge water through the first water pipe assembly;

[0006] Mode 2: Remove the connecting pipe from between the water intake pipe and the first water pipe assembly, and discharge water through the water intake pipe;

[0007] Mode three: remove the connecting pipe from between the water intake pipe and the first water pipe assembly, install an elbow on the water outlet of the water intake pipe, and discharge water through the elbow.

[0008] While this design has improved the system's flexibility to a certain extent, it also has some drawbacks. Specifically, when switching between different operating modes, not only do additional accessories such as connecting pipes and elbows need to be prepared, but these components also take up a relatively large amount of space, increasing the vehicle's carrying capacity, especially within limited loading space. Utility Model Content

[0009] To this end, it is necessary to provide a water supply and drainage vehicle and its drainage device to solve the problem that when performing conversions between different working conditions, not only additional accessories such as connecting pipes and elbows need to be prepared, but these components also occupy a relatively large space, increasing the burden on the vehicle.

[0010] To achieve the above objectives, this embodiment provides a water supply and drainage device, comprising:

[0011] First pipeline;

[0012] a third pipeline, the third pipeline being arranged side by side with the first pipeline and located below the first pipeline;

[0013] a supporting mechanism, the supporting mechanism being configured to support the first pipe and the third pipe; and

[0014] The second pipe is U-shaped and includes a first connecting pipe and a second connecting pipe symmetrically arranged. The first connecting pipe and the second connecting pipe are elbows. The water outlet of the first pipe is detachably connected to the water inlet of the first connecting pipe, the water inlet of the second connecting pipe is detachably connected to the water outlet of the first connecting pipe, and the water outlet of the second connecting pipe is detachably connected to the water inlet of the second pipe.

[0015] Furthermore, when the first connecting pipe is connected to the water outlet of the first pipe, the water outlet of the first connecting pipe can face different directions according to different installation methods.

[0016] Furthermore, quick-connect joints are provided on the water outlet of the first pipe and the water inlet of the first connecting pipe, the water inlet of the second connecting pipe and the water outlet of the first connecting pipe, and the water outlet of the second connecting pipe and the water inlet of the second pipe, and the quick-connect joints include rotary joints or clamp joints.

[0017] Furthermore, the rotary joint is a three-claw joint.

[0018] Furthermore, a sealing ring is provided at the joint portion of the quick connector.

[0019] Furthermore, the first connecting tube and / or the second connecting tube is provided with a handle.

[0020] Furthermore, it also includes a lifting mechanism, which is connected to the supporting mechanism and is used to make the supporting mechanism pitch.

[0021] Furthermore, the support mechanism includes a support frame and a sliding frame, the sliding frame is slidably provided on the support frame and is located above the support frame, the first pipe is a multi-stage telescopic pipe, wherein the first-stage telescopic pipe is slidably provided on the sliding frame, and the third pipe is provided on the support frame and is located below the support frame.

[0022] Furthermore, it also includes a water pump, which is arranged on the water inlet of the first pipeline.

[0023] To achieve the above-mentioned purpose, this embodiment further provides a water supply and drainage vehicle, comprising the water supply and drainage device as described in any one of the above-mentioned embodiments.

[0024] Different from the existing technology, the above technical solution has the following beneficial effects:

[0025] The second pipe is a U-shaped structure, composed of two symmetrically arranged 90° elbows, namely the first connecting pipe and the second connecting pipe. These two elbows are combined together through a detachable connection, allowing the entire second pipe to flexibly change direction. These two elbows can also be used separately with water supply and drainage devices. The second pipe adopts a segmented structure, and the direction and layout of the pipe can be quickly adjusted according to site conditions. For example, water can be discharged through the first connecting pipe to adapt to underground drainage, deep pit drainage, or through a third pipe. The segmented second pipe can replace the elbows in the background technology, serving two purposes, allowing for compact storage inside the transportation vehicle, improving space utilization, and reducing production costs.

[0051] See also Figures 1 to 8 This embodiment provides a water supply and drainage device that is easy to disassemble, including:

[0052] First pipeline 1;

[0053] The third pipeline 3 is arranged side by side with the first pipeline 1 and is located below the first pipeline 1;

[0054] A supporting mechanism 6, the supporting mechanism 6 is used to support the first pipe 1 and the third pipe 3; and

[0055] The second pipe 2 is U-shaped and includes a first connecting pipe 21 and a second connecting pipe 22 symmetrically arranged. The first connecting pipe 21 and the second connecting pipe 22 are 90° elbows. The water outlet of the first pipe 1 is detachably connected to the water inlet of the first connecting pipe 21, the water inlet of the second connecting pipe 22 is detachably connected to the water outlet of the first connecting pipe 21, and the water outlet of the second connecting pipe 22 is detachably connected to the water inlet of the second pipe 2.

[0056] The first and third pipes 1 and 3 are arranged vertically and, preferably, in parallel. This arrangement facilitates smooth water flow from the first pipe 1 to the third pipe 3. However, in practice, due to assembly issues, the first and third pipes 1 and 3 may be slightly tilted. Such technical solutions fall within the scope of protection of this application. In some embodiments, the first and third pipes 1 and 3 are designed to be tilted from the outset, for example, at a steep angle of 30, 40, or 60 degrees.

[0057] The second pipeline 2 is a U-shaped structure, consisting of two symmetrically arranged 90° elbows, namely a first connecting pipe 21 and a second connecting pipe 22 . Figure 2 An exploded view of the first connecting pipe 21 and the second connecting pipe 22 is shown. Figure 3 A schematic diagram shows the assembly of the first connecting pipe 21 and the second connecting pipe 22. The two elbows are combined together through a detachable connection, allowing the entire second pipe 2 to flexibly change direction. The two elbows can also be used separately with water supply and drainage devices. The second pipe 2 is segmented, allowing the direction and layout of the pipe to be quickly adjusted according to site conditions. For example, water can be discharged through the first connecting pipe 21 for underground drainage or deep pit drainage, or through the third pipe 3. The segmented second pipe 2 can replace the elbows in the background art, serving two purposes, allowing for compact storage inside the vehicle, improving space utilization, and reducing production costs.

[0058] In this embodiment, when the first connecting pipe is connected to the water outlet of the first pipe, the water outlet of the first connecting pipe can face different directions depending on the installation method. The quick-connect connectors (such as rotary quick-connect connectors and clamp-type quick-connect connectors) and flanges described below can provide multiple installation methods to adjust the orientation of the first connecting pipe. In actual use, the orientation of the water outlet of the first connecting pipe can be selected according to specific needs:

[0059] The first water outlet direction: the second pipe 2 needs to be installed between the first pipe 1 and the third pipe 3 assembly, then the first connecting pipe 21 is installed on the first pipe 1, and the water outlet of the first connecting pipe 21 is facing the first direction (such as downward), so that it can connect to the second connecting pipe 22 located below.

[0060] The second water outlet direction: if underground drainage or deep pit drainage is required, the first connecting pipe 21 is installed on the first pipe 1, and the water outlet of the first connecting pipe 21 is facing the second direction. The second direction can be upward. When the subsequent lifting mechanism 7 raises the water outlet of the first pipe 1, the water outlet of the first connecting pipe 21 can face backward to facilitate backward water supply. The second direction can also be the front or the right, depending on the water supply direction.

[0061] See also Figures 1 to 3 、 Figure 5 In this embodiment, quick connectors 4 are provided on the water outlet of the first pipe 1 and the water inlet of the first connecting pipe 21, the water inlet of the second connecting pipe 22 and the water outlet of the first connecting pipe 21, and the water outlet of the second connecting pipe 22 and the water inlet of the second pipe 2. The design of the quick connector 4 makes the connection and disconnection operations between the pipes very quick and easy, greatly reducing the installation and disassembly time.

[0062] In this embodiment, the quick connector 4 is a rotary connector, a clamp connector, etc. Preferably, the quick connector 4 is a rotary connector, such as a three-claw connector 41, a six-claw connector, a threaded rotary connector, etc. The user only needs to align the two interfaces and rotate them to complete the connection. Figure 2 As shown, a three-prong connector 41 is provided at the junction of the first connecting tube 21 and the second connecting tube 22. Rotating the three prongs allows the first connecting tube to be installed in a variety of ways, with the water outlet facing the desired direction. Preferably, in actual use, the multiple quick-connect connectors 4 are of the same type and specification, which facilitates procurement, controls costs, and ensures interchangeability and operational consistency.

[0063] In some embodiments, the detachable connection between the pipelines is a flange connection, which has the disadvantage that the disassembly of the flange is not as convenient as the disassembly of the quick connector 4 .

[0064] In this embodiment, the quick-connect connector 4 has a sealing ring at the joint to ensure a tight seal and prevent liquid leakage. The operator aligns the outlet of the first pipe 1 with the water inlet of the first connecting pipe 21 and then connects them by twisting or snapping. Similarly, the water inlet of the second connecting pipe 22 is aligned with the water outlet of the first connecting pipe 21 and connected, and the water outlet of the second connecting pipe 22 is aligned with the water inlet of the second pipe 2 and connected. During this process, the sealing ring is compressed, forming a tight seal.

[0065] See also Figure 2 and Figure 3 In this embodiment, handles 23 are provided on the first connecting pipe 21 and / or the second connecting pipe 22. These handles 23 can be annular handles 23 fixed to the outer wall of the pipe, hook-shaped handles 23, or other forms of gripping structures. The handles 23 are designed to facilitate operators to install, remove, and carry the second pipe 2 more conveniently. When it is necessary to install or remove the second pipe 2, the operator can easily operate through the handles 23 provided on the first connecting pipe 21 and / or the second connecting pipe 22. The handles 23 provide a stable gripping point, reducing the risk of accidental injury to the operator due to slipping hands or unstable grip, especially in slippery or complex working environments.

[0066] See also Figure 6 In this embodiment, the support mechanism 6 includes a support frame 61 and a sliding frame 62. The sliding frame 62 is slidably provided on the support frame 61 and is located above the support frame 61. The first pipe 1 is a multi-stage telescopic tube, in which the first-stage telescopic tube is slidably provided on the sliding frame 62. The third pipe 3 is provided on the support frame 61 and is located below the support frame 61.

[0067] The sliding frame 62 is installed above the support frame 61 and can slide horizontally on the support frame 61. The design of the sliding frame 62 allows the height and position of the first pipe 1 to be flexibly adjusted. The first pipe 1 is designed as a multi-stage telescopic tube, which can be extended and retracted to adapt to different height requirements. One of the first-stage telescopic tubes of the first pipe 1 can be slidably arranged on the sliding frame 62. The height and position of the first pipe 1 can be adjusted by moving the sliding frame 62 and extending and retracting the telescopic tube. The third pipe 3 is fixed below the support frame 61 and is relatively fixed in position. It is responsible for discharging the water flow to a predetermined position. It should be noted that when the first pipe 1 is telescopically moved, the second pipe 2 can be disassembled to avoid interference with each other. When the second pipe 2 is installed in place, the telescopic tube of the first stage where the water outlet of the first pipe 1 is located is stationary, but the other stages of telescopic tubes can be telescopically moved toward the water inlet, close to the water source.

[0068] See also Figure 6In this embodiment, the sliding connection between the support frame 61 and the sliding frame 62, and the sliding frame 62 and the first pipeline 1 can adopt a pulley and groove assembly 63.

[0069] See also Figure 7 and Figure 8 In this embodiment, the water supply and drainage device further includes a lifting mechanism 7 , which is connected to the supporting mechanism 6 and is used to make the supporting mechanism 6 pitch, thereby adjusting the angles of the first pipe 1 and the third pipe 3 .

[0070] See also Figure 7 and Figure 8 In this embodiment, the lifting mechanism 7 includes a lifting cylinder 71 and a lifting bracket 72. The support mechanism 6 (which can be the support bracket 61 mentioned above) is arranged on the chassis of the water supply and drainage vehicle through the lifting bracket 72. The support mechanism 6 can rotate relative to the lifting bracket 72. The two ends of the lifting cylinder 71 are respectively hinged to the support mechanism 6 (which can be the support bracket 61 mentioned below) and the chassis. The support mechanism 6 is driven to pitch by the extension and retraction of the lifting cylinder 71, thereby adjusting the angles of the first pipe 1 and the third pipe 3.

[0071] See also Figure 1 In this embodiment, the water supply and drainage device further includes a water pump 5 , which is disposed on the water inlet of the first pipe 1 . The water pump 5 can draw external water into the first pipe 1 .

[0072] See also Figure 1 In this embodiment, the first connecting pipe 21 and the second connecting pipe 22 are arc-shaped pipes with a 90° bend. When the two are connected, they form a U-shape. The first pipe 1 is parallel to the third pipe 3, and the first pipe 1, the second pipe 2, and the third pipe 3 also form a U-shape.

[0073] See also Figures 1 to 8 This embodiment also provides a water supply and drainage vehicle, including the water supply and drainage device as described in any one of the above embodiments.
