Description

A water supply and drainage vehicle and its water supply and drainage device Technical Field

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

[0002] In the field of emergency rescue, water supply and drainage vehicles are crucial equipment. They can quickly and effectively 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 emergencies. To meet diverse operational needs, existing water supply and drainage vehicles are typically equipped with multiple pipeline 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, including 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 inlet end of the water intake pipe and the outlet end of the first water pipe assembly are located on the same side, the outlet end of the water intake pipe and the inlet end of the first water pipe assembly are located on the same side, the water pump is installed at the inlet of the water intake pipe, the 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 inlet end of the first water pipe assembly, and the outlet end of the first water pipe assembly is used to connect a water intake device or a water pipe.

[0004] In practical applications, the above-mentioned water intake system can adapt to two main operating modes:

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

[0006] Mode 2 involves disconnecting the connecting pipe from the water intake pipe and the first water pipe assembly, and then allowing water to flow out through the water intake pipe.

[0007] In mode three, the connecting pipe is disconnected from the water intake pipe and the first water pipe assembly, and an elbow is installed at the outlet of the water intake pipe, through which water flows out.

[0008] While this design has improved the system's flexibility to some extent, it has also revealed some shortcomings. In particular, when performing transitions between different operating conditions, not only are additional accessories such as connecting pipes and elbows required, but these components also occupy a relatively large amount of space, increasing the vehicle's carrying burden, especially within limited loading space. Utility Model Content

[0009] Therefore, there is a need to provide a water supply and drainage vehicle and its drainage device to solve the problem that when performing different working conditions, not only do additional accessories such as connecting pipes and elbows need to be prepared, but these components also occupy a relatively large space, increasing the burden of carrying the vehicle.

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

[0011] First pipeline;

[0012] A third pipe is arranged side by side with the first pipe and located below the first pipe;

[0013] A support mechanism, wherein the support mechanism is used 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 outlet of the first pipe is detachably connected to the inlet of the first connecting pipe, the inlet of the second connecting pipe is detachably connected to the outlet of the first connecting pipe, and the outlet of the second connecting pipe is detachably connected to the inlet of the second pipe.

[0015] Furthermore, when the first connecting pipe is connected to the outlet of the first pipe, the outlet of the first connecting pipe can face different directions depending on the installation method.

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

[0017] Furthermore, the rotary connector is a three-jaw connector.

[0018] Furthermore, the quick-connect fitting has a sealing ring at the mating part.

[0019] Furthermore, the first connecting pipe and / or the second connecting pipe are provided with handles.

[0020] Furthermore, it also includes a lifting mechanism connected to the support mechanism for tilting the support mechanism.

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

[0022] Furthermore, it also includes a water pump, which is installed at the inlet of the first pipe.

[0023] To achieve the above objectives, this embodiment also provides a water supply and drainage vehicle, including the water supply and drainage device as described in any of the above embodiments.

[0024] Unlike existing technologies, the above technical solution has the following beneficial effects:

[0025] The second pipeline has a U-shaped structure, formed by two symmetrically arranged 90° elbows, namely the first connecting pipe and the second connecting pipe. These two elbows are combined in a detachable manner, allowing the entire second pipeline to flexibly change direction. These two elbows can also be used independently with water supply and drainage devices. The second pipeline adopts a segmented design, which can quickly adjust the direction and layout of the pipeline according to site conditions. For example, water can exit through the first connecting pipe to adapt to underground drainage and deep pit drainage, or water can exit through the third pipeline. The segmented second pipeline can replace the elbows in the prior art, serving two purposes, allowing for compact storage inside the transport vehicle, improving space utilization, and reducing production costs.

[0051] Please refer to 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 pipe 3 is arranged side by side with the first pipe 1 and is located below the first pipe 1;

[0054] Support mechanism 6, which supports 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 arranged symmetrically. The first connecting pipe 21 and the second connecting pipe 22 are 90° bends. The outlet of the first pipe 1 is detachably connected to the inlet of the first connecting pipe 21, the inlet of the second connecting pipe 22 is detachably connected to the outlet of the first connecting pipe 21, and the outlet of the second connecting pipe 22 is detachably connected to the inlet of the second pipe 2.

[0056] The first pipe 1 and the third pipe 3 are arranged vertically, and preferably, they are arranged parallel to each other. This arrangement facilitates smooth water flow from the first pipe 1 to the third pipe 3. However, in practical applications, due to assembly issues, the first pipe 1 and the third pipe 3 may be slightly tilted, and such technical solutions also fall within the scope of protection of this application. In some embodiments, the first pipe 1 and the third pipe 3 are designed to be tilted from the outset, for example, forming large angles such as 30 degrees, 40 degrees, or 60 degrees.

[0057] The second pipe 2 has a U-shaped structure, consisting of two symmetrically arranged 90° elbows, namely the first connecting pipe 21 and the second connecting pipe 22. Figure 2 shows an exploded view of the first connecting pipe 21 and the second connecting pipe 22, and Figure 3 shows a schematic diagram of the first connecting pipe 21 and the second connecting pipe 22 assembled together. These two elbows are combined in a detachable connection manner, allowing the entire second pipe 2 to flexibly change direction. These two elbows can also be used independently with water supply and drainage devices. The second pipe 2 adopts a segmented design, which can quickly adjust the direction and layout of the pipe according to site conditions. For example, water can exit through the first connecting pipe 21 to adapt to underground drainage and deep pit drainage, or water can exit through the third pipe 3. The segmented second pipe 2 can replace the elbows in the prior art, serving two purposes, allowing for compact storage inside transportation vehicles, improving space utilization, and reducing production costs.

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

[0059] The first water outlet orientation: If 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 outlet of the first connecting pipe 21 is oriented in the first direction (as shown below), so that it can be connected to the second connecting pipe 22 located below.

[0060] The second type of water outlet direction: If drainage is required in the well or deep pit, a first connecting pipe 21 is installed on the first pipe 1, so that the outlet of the first connecting pipe 21 faces the second direction. The second direction can be upward. When the lifting mechanism 7 raises the outlet of the first pipe 1, the outlet of the first connecting pipe 21 can face backward to facilitate water delivery to the rear. The second direction can also be forward or right, depending on the direction of water delivery.

[0061] Please refer to Figures 1 to 3 and Figure 5. In this embodiment, quick-connect couplings 4 are provided on the outlet of the first pipe 1 and the inlet of the first connecting pipe 21, the inlet of the second connecting pipe 22 and the outlet of the first connecting pipe 21, and the outlet of the second connecting pipe 22 and the inlet of the second pipe 2. The design of the quick-connect couplings 4 makes the connection and disconnection 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, clamp connector, etc. Preferably, the quick-connector 4 is a rotary connector, such as a three-jaw connector 41, a six-jaw connector, or a threaded rotary connector. The user only needs to align the two interfaces and rotate to complete the connection. As shown in Figure 2, a three-jaw connector 41 is set at the position where the first connecting pipe 21 and the second connecting pipe 22 are connected. By rotating, the three jaws interlock to achieve locking. The three-jaw connector allows the first connecting pipe to have multiple installation methods, so that its outlet faces the desired direction. Preferably, in actual use, the above-mentioned quick-connectors 4 are all 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 pipes is a flange connection, but the disadvantage is that the flange is not as easy to remove as the quick-connect fitting 4.

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

[0065] Referring to Figures 2 and 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, hook handles 23, or other forms of gripping structures fixed to the outer wall of the pipe. The handles 23 are designed to facilitate the installation, disassembly, and handling of the second pipe 2 by the operator. When it is necessary to install or disassemble the second pipe 2, the operator can easily operate using 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 caused by the operator slipping or losing their grip, especially in wet or complex working environments.

[0066] Please refer to 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 disposed on the support frame 61 and located above the support frame 61. The first pipe 1 is a multi-stage telescopic pipe, wherein the first stage telescopic pipe is slidably disposed on the sliding frame 62, and the third pipe 3 is disposed on the support frame 61 and 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 for flexible adjustment of the height and position of the first pipe 1. The first pipe 1 is designed as a multi-stage telescopic pipe, which can extend and retract to adapt to different height requirements. One stage of the telescopic pipe 1 is slidably mounted on the sliding frame 62. By moving the sliding frame 62 and extending and retracting the telescopic pipe, the height and position of the first pipe 1 can be adjusted. The third pipe 3 is fixed below the support frame 61, with a relatively fixed position, and is responsible for discharging water to a predetermined location. It should be noted that the second pipe 2 can be disassembled during the extension and retraction of the first pipe 1 to avoid interference. When the second pipe 2 is installed in place, the telescopic pipe at the outlet of the first pipe 1 remains stationary, but the other stages of telescopic pipes can extend and retract towards the inlet, closer to the water source.

[0068] Please refer to Figure 6. In this embodiment, the sliding connection between the support frame 61 and the sliding frame 62, and between the sliding frame 62 and the first pipe 1, can be achieved by using a pulley and groove assembly 63.

[0069] Please refer to Figures 7 and 8. In this embodiment, the water supply and drainage device also includes a lifting mechanism 7, which is connected to the support mechanism 6 and is used to tilt the support mechanism 6, thereby adjusting the angle of the first pipe 1 and the third pipe 3.

[0070] Please refer to Figures 7 and 8. In this embodiment, the lifting mechanism 7 includes a lifting cylinder 71 and a lifting bracket 72. The support mechanism 6 (which may be the support frame 61 mentioned above) is mounted on the chassis of the water supply and drainage vehicle via 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 may be the support frame 61 mentioned below) and the chassis. The extension and retraction of the lifting cylinder 71 drives the support mechanism 6 to pitch, thereby adjusting the angle of the first pipe 1 and the third pipe 3.

[0071] Please refer to Figure 1. In this embodiment, the water supply and drainage device also includes a water pump 5, which is installed at the inlet of the first pipe 1. The water pump 5 can bring external water into the first pipe 1.

[0072] Please refer to 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 they are connected, they form a U-shaped shape. The first pipe 1 is parallel to the third pipe 3. The first pipe 1, the second pipe 2, and the third pipe 3 also form a U-shaped shape.

[0073] Please refer to 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 of the above embodiments.

[0074] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
