Description

Technical Field

[0001] This utility model relates to the field of sanitation vehicle technology, and more specifically, to a tank assembly and a combined dredging vehicle. Background Technology

[0002] The combined dredging truck, also known as a sewer dredging truck, is a sanitation vehicle that integrates high-pressure cleaning and vacuum suction functions. It is widely used for dredging, cleaning, and sewage suction operations in urban sewers, rainwater wells, sedimentation wells, and ditches. This equipment typically consists of a chassis, tank assembly, high-pressure flushing system, vacuum suction system, hydraulic transmission system, and control system.

[0003] The tank assembly typically comprises a clean water tank and a wastewater tank, and is generally constructed using an integral welding process: two clean water tanks are symmetrically welded to both sides of the wastewater tank, with the outer wall of the wastewater tank simultaneously serving as the inner wall of the clean water tank. However, this structural design has the following technical drawbacks: First, it requires high precision in the welding process, making the tank anti-corrosion treatment difficult to implement; second, the wastewater tank wall must withstand the dual corrosion effects of internal wastewater and external clean water, significantly reducing the equipment's service life; furthermore, welding defects and leakage problems caused by long-term use are difficult to pinpoint accurately, affecting equipment maintenance efficiency.

[0004] In other words, existing tank assemblies suffer from high manufacturing process requirements, low corrosion resistance, and difficulty in maintenance, which seriously affect the reliability and service life of the tank assembly. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] As described in the background section, existing tank assemblies suffer from high manufacturing process requirements, low corrosion resistance, and difficulty in maintenance, severely impacting their reliability and service life. Specifically, the clean water and wastewater tanks in these assemblies are typically manufactured using an integral welding process, where two clean water tanks are symmetrically welded to both sides of the wastewater tank, with the outer wall of the wastewater tank simultaneously serving as the inner wall of the clean water tank. However, this method demands high precision in the welding process, making anti-corrosion treatment difficult. Secondly, the wastewater tank wall must withstand the dual corrosion from both internal wastewater and external clean water, significantly reducing the equipment's lifespan. Furthermore, welding defects and leaks caused by long-term use are difficult to pinpoint accurately, affecting equipment maintenance efficiency.

[0029] Based on this, please refer to Figures 1-15 The present invention provides a tank assembly 100 and a combined dredging vehicle 1000, which can effectively improve the aforementioned technical problems. Specifically, it is easy to maintain, simple to assemble, and not easily corroded, thus improving the reliability and service life of the tank assembly 100. The tank assembly 100 and the combined dredging vehicle 1000 will be described in detail below.

[0030] Please refer to Figure 1 and Figure 2 , Figure 1 This is a first-view structural schematic diagram of the combined dredging vehicle 1000 provided in this embodiment. Figure 2 This is a second-view structural schematic diagram of the combined dredging vehicle 1000 provided in this embodiment. (Combined with...) Figure 1 and Figure 2 The combined dredging vehicle 1000 includes a tank assembly 100 and a chassis 200, with the tank assembly 100 mounted on the chassis 200.

[0031] For details, please refer to Figure 3 and Figure 4 , Figure 3 This is a first-view structural schematic diagram of the tank assembly 100 provided in this embodiment. Figure 4 This is a second-view structural schematic diagram of the tank assembly 100 provided in this embodiment. (Combined with...) Figure 3 and Figure 4The tank assembly 100 includes a first clean water tank 11, a second clean water tank 12, a wastewater tank 20, multiple upper connecting structures 30, and multiple lower connecting structures 40. The first clean water tank 11 and the second clean water tank 12 are spaced apart, and the wastewater tank 20 is disposed between the first clean water tank 11 and the second clean water tank 12. The upper part of the first clean water tank 11 is connected to the upper part of the wastewater tank 20 through at least one upper connecting structure 30, and the upper part of the second clean water tank 12 is connected to the upper part of the wastewater tank 20 through at least one upper connecting structure 30. The lower part of the first clean water tank 11 is connected to the lower part of the wastewater tank 20 through at least one lower connecting structure 40, and the lower part of the second clean water tank 12 is connected to the lower part of the wastewater tank 20 through at least one lower connecting structure 40.

[0032] As is easily understood, the first clean water tank 11 and the sewage tank 20 are connected and fixed together by an upper connecting structure 30 and a lower connecting structure 40, and the second clean water tank 12 and the sewage tank 20 are also connected and fixed together by an upper connecting structure 30 and a lower connecting structure 40. In other words, the first clean water tank 11, the second clean water tank 12, and the sewage tank 20 of the tank assembly 100 are all independent tanks, without being integrally welded together, making overall assembly convenient and the installation process simple. Furthermore, the clean water tank and the sewage tank 20 do not share a wall panel, thus avoiding dual corrosion from sewage and clean water, resulting in strong corrosion resistance. At the same time, it also facilitates the implementation of tank anti-corrosion treatment processes, leading to high maintenance efficiency, thereby improving the reliability and service life of the tank assembly 100.

[0033] Combination Figures 1-4 Furthermore, the combined dredging vehicle 1000 also includes a high-pressure dredging reel system 600, a suction boom system 801, a high-pressure water system 802, a primary overflow prevention system 803, a secondary overflow prevention system 804, a vacuum suction system 805, and a centrifugal pump 806. The centrifugal pump 806 is connected to the sewage tank 20 and is used to discharge the sewage in the sewage tank 20. It can also operate simultaneously with the vacuum suction system 805.

[0034] Understandably, in this embodiment, the suction boom system 801, the high-pressure water system 802, the primary overflow prevention system 803, the secondary overflow prevention system 804, and the vacuum suction system 805 are all connected to the tank assembly 100.

[0035] It should be noted that, in order to improve the connection stability between the first clean water tank 11 and the second clean water tank 12 and the sewage tank 20, the number of upper connection structures 30 and lower connection structures 40 between the first clean water tank 11 and the sewage tank 20 can be multiple, and the number of upper connection structures 30 and lower connection structures 40 between the second clean water tank 12 and the sewage tank 20 can also be multiple.

[0036] For example, please refer to Figure 5 and Figure 6 , Figure 5 This is a third-view structural schematic diagram of the tank assembly 100 provided in this embodiment. Figure 6 This is a fourth-view structural schematic diagram of the tank assembly 100 provided in this embodiment. (Combined with...) Figure 5 and Figure 6 In this embodiment, there are six upper connecting structures 30 and six lower connecting structures 40. Furthermore, there are three upper connecting structures 30 and three lower connecting structures 40 between the first clean water tank 11 and the sewage tank 20, and three upper connecting structures 30 and three lower connecting structures 40 between the second clean water tank 12 and the sewage tank 20. This symmetrical arrangement ensures that the installation forces on the first clean water tank 11 and the second clean water tank 12 on opposite sides of the sewage tank 20 are balanced, thereby improving the stability of the combined dredging vehicle 1000 during travel and operation.

[0037] Of course, in other embodiments, the number of upper connecting structures 30 and lower connecting structures 40 between the first clean water tank 11 and the sewage tank 20 can also be one, two, or four, etc.; similarly, the number of upper connecting structures 30 and lower connecting structures 40 between the second clean water tank 12 and the sewage tank 20 can also be one, two, or four, etc.

[0038] Furthermore, in order to improve the overall structural strength of the sewage tank 20, the tank assembly 100 also includes a constraint structure 50, which is disposed around the sewage tank 20 and at least partially surrounds the sewage tank 20; the upper connecting structure 30 and the lower connecting structure 40 are both disposed on the constraint structure 50 and are both connected to the first clean water tank 11 or the second clean water tank 12.

[0039] As is easily understood, the constraint structure 50 can also provide installation points for the upper connecting structure 30 and the lower connecting structure 40, which facilitates the installation and fixing of the two, and to a certain extent improves the installation stability of the upper connecting structure 30 and the lower connecting structure 40, while also improving assembly efficiency.

[0040] It should be noted that in this embodiment, the constraint structure 50 is specifically a U-shaped clamp structure with the opening facing upwards. That is, the constraint structure 50 is set around the circumference of the sewage tank 20, extending from the lower part of the sewage tank 20 to the upper part, and the two ends of the constraint structure 50 are not connected at the upper part of the sewage tank 20. The purpose of this setting is that, firstly, according to actual operation, the water in the tank will not be full, so there is no need to reinforce the top; secondly, the negative pressure of the entire hollow tank is mainly concentrated in the middle position, so it is sufficient to reinforce the lower middle part of the tank; thirdly, the top of the sewage tank 20 is usually equipped with an overflow valve and other structures. If the constraint structure 50 is extended to the top of the tank, it will occupy the top space and easily interfere with other components; in addition, this U-shaped clamp structure can also improve the overall aesthetics of the tank assembly 100.

[0041] Combination Figure 5 and Figure 6 It should also be noted that, specifically in this embodiment, the number of constraint structures 50 is three, and each constraint structure 50 is provided with two upper connecting structures 30 and two lower connecting structures 40. Of course, in other embodiments, the number of constraint structures 50 can also be one, two, or four, etc.

[0042] Combination Figures 3-6 The tank assembly 100 also includes a connecting pipe 60, with its two ends connected to the first clean water tank 11 and the second clean water tank 12, respectively. By connecting the first clean water tank 11 and the second clean water tank 12, the clean water inside both tanks can flow between them. During operation, the combined cleaning truck 1000 ensures that the water levels in the first clean water tank 11 and the second clean water tank 12 remain consistent, thus maintaining equal weight on both sides of the vehicle and improving stability and safety. Furthermore, the connecting pipe 60 balances the air pressure inside the first clean water tank 11 and the second clean water tank 12, resulting in smoother water flow and improving cleaning efficiency to some extent.

[0043] It should be noted that, in this embodiment, the connecting pipe 60 is specifically located below the sewage tank 20 and near the front end of the sewage tank 20. This avoids interference between the connecting pipe 60 and other components above the tank assembly 100, and also avoids interference between the connecting pipe 60 and components located at the rear end of the tank assembly 100, saving installation space and facilitating the installation and subsequent maintenance and replacement of the connecting pipe 60.

[0044] Please continue to combine Figure 3Specifically, the connecting pipe 60 includes a first flexible hose 61, a second flexible hose 62, and a rigid pipe 63. The first flexible hose 61, the rigid pipe 63, and the second flexible hose 62 are connected in sequence, and the first flexible hose 61 is connected to the first clean water tank 11, and the second flexible hose 62 is connected to the second clean water tank 12.

[0045] Understandably, the first hose 61 and the second hose 62 are flexible and adaptable, facilitating easy installation and connection with the first water tank 11 and the second water tank 12, thus improving assembly efficiency. Furthermore, the rigid pipe 63 ensures the overall structural strength of the connecting pipe 60, preventing it from swaying during vehicle operation or work.

[0046] Furthermore, in order to improve the installation stability of the rigid pipe 63, in this embodiment, the connecting pipe 60 also includes a mounting bracket 64, which is disposed on the sewage tank 20 and fixedly connected to the rigid pipe 63.

[0047] It should be noted that there can be multiple mounting brackets 64, which are spaced apart. For example, in this embodiment, there are two mounting brackets 64. Of course, in other embodiments, there can be one, three, or four mounting brackets 64, etc.

[0048] Please refer to Figure 7 , Figure 7 This is a schematic diagram showing the connection between the first clean water tank 11, the upper connecting structure 30, and the sewage tank 20 provided in this embodiment, in conjunction with... Figure 3 and Figure 7 Specifically, the upper connecting structure 30 includes a first upper connecting frame 31, a second upper connecting frame 32, and a first fastener 33. The first upper connecting frame 31 is disposed on the upper part of the first clean water tank 11 or the second clean water tank 12, and the second upper connecting frame 32 is disposed on the upper part of the sewage tank 20. The first upper connecting frame 31 is connected to the second upper connecting frame 32 through the first fastener 33.

[0049] In other words, during the actual assembly process, the first upper connecting frame 31 can be welded to the upper part of the first clean water tank 11 or the second clean water tank 12, and the second upper connecting frame 32 can be welded to the upper part of the sewage tank 20. Then, the first upper connecting frame 31 and the second upper connecting frame 32 can be overlapped and locked and fixed using the first fastener 33, making the assembly convenient and quick.

[0050] Please refer to Figure 8 , Figure 8 This is a schematic diagram showing the connection between the second clean water tank 12, the lower connecting structure 40, and the sewage tank 20 provided in this embodiment, in conjunction with... Figure 3 and Figure 8Specifically, the lower connecting structure 40 includes a first lower connecting frame 41, a second lower connecting frame 42, and a second fastener 43. The first lower connecting frame 41 is disposed at the lower part of the first clean water tank 11 or the second clean water tank 12, and the second lower connecting frame 42 is disposed at the lower part of the sewage tank 20. The first lower connecting frame 41 is connected to the second lower connecting frame 42 by the second fastener 43. Through the cooperation of the first lower connecting frame 41, the second lower connecting frame 42, and the second fastener 43, the assembly efficiency between the clean water tank and the sewage tank 20 can also be improved.

[0051] Combination Figure 7 and Figure 8 It should be noted that, specifically in this embodiment, both the second upper connecting frame 32 and the second lower connecting frame 42 are disposed on the constraint structure 50.

[0052] Furthermore, in order to improve the installation stability of the first upper connecting frame 31, the upper connecting structure 30 also includes a first reinforcing plate 34, which is disposed on the upper part of the first clean water tank 11 or the second clean water tank 12, and the first upper connecting frame 31 is disposed on the first reinforcing plate 34.

[0053] Similarly, in order to improve the installation stability of the first lower connecting frame 41, the lower connecting structure 40 also includes a second reinforcing plate 44, which is disposed at the lower part of the first clean water tank 11 or the second clean water tank 12, and the first lower connecting frame 41 is disposed on the second reinforcing plate 44.

[0054] It should be noted that, in this embodiment, the first reinforcing plate 34 and the second reinforcing plate 44 are connected and fixed to the first clean water tank 11 or the second clean water tank 12 by welding, and both the first reinforcing plate 34 and the second reinforcing plate 44 are L-shaped reinforcing plates, which can increase the welding area and further improve the connection strength between the first clean water tank 11 or the second clean water tank 12 and the sewage tank 20.

[0055] To facilitate assembly and improve the installation stability between the clean water tank and the sewage tank 20, in this embodiment, the first upper connecting frame 31 overlaps the side of the second upper connecting frame 32 away from the sewage tank 20, and the first lower connecting frame 41 overlaps the side of the second lower connecting frame 42 close to the sewage tank 20.

[0056] In other words, the installation positions of the first upper connecting frame 31 and the second upper connecting frame 32 between the first clean water tank 11 and the sewage tank 20, or between the second clean water tank 12 and the sewage tank 20, are actually misaligned with the installation positions of the first lower connecting frame 41 and the second lower connecting frame 42. When assembling the first clean water tank 11 or the second clean water tank 12 with the sewage tank 20, the first upper connecting frame 31 can overlap the second upper connecting frame 32, and the first lower connecting frame 41 can also overlap the second lower connecting frame 42, thereby ensuring that the first clean water tank 11 or the second clean water tank 12 can be stably aligned with the sewage tank 20 first, and then connected and fixed by the first fastener 33 or the second fastener 43.

[0057] Please continue to combine Figure 1 In order to facilitate the storage of working tools, the combined dredging vehicle 1000 also includes a first toolbox 301, which is located on the chassis 200 and on the side of the first clean water tank 11 near the sewage tank 20.

[0058] Combination Figure 2 Similarly, the combined dredging vehicle 1000 also includes a second toolbox 302, which is located on the chassis 200 and on the side of the second clean water tank 12 near the sewage tank 20.

[0059] That is, in this embodiment, toolboxes are provided on both sides of the sewage tank 20, and the first toolbox 301 and the second toolbox 302 can also be understood as left and right toolboxes.

[0060] It should be noted that the first toolbox 301 and the second toolbox 302 are located below the first water tank 11 and the second water tank 12, respectively, and are flush with the outer sides of the first toolbox 301 and the second toolbox 302, thereby ensuring the overall coordination and aesthetics of the vehicle.

[0061] For details, please refer to Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of the structure of the first toolbox 301 and the second toolbox 302 provided in this embodiment.
