[0033] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0034] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, this utility model provides a modified sewage suction truck, comprising:

[0035] The cleaning head storage structure includes a base and a sliding plate 5. The sliding plate 5 is slidably mounted on the base. Multiple retainers 4 are provided on one side of the sliding plate 5. The retainers 4 are used for threaded connection with the bottom of the cleaning head 3.

[0036] The warning label storage structure includes a fixed end frame 8 and a movable end frame 11. One end of the movable end frame 11 is rotatably connected to one end of the fixed end frame 8. The movable end frame 11 has at least two first mounting holes, and the radial dimension of the first mounting hole is smaller than the bottom radial dimension of the warning label 10.

[0037] The maintenance tool storage structure includes at least two pairs of clamping plate assemblies and a placement rack 15. One end of the placement rack 15 is connected to one side of the clamping plate assembly. The plane on which the placement rack 15 is located forms an angle of 15° to 35° with the horizontal plane. The placement rack 15 is provided with a plurality of second mounting holes for engaging and fixing with the head structure of the maintenance tool 16.

[0038] The base is installed in the garbage bin of the vacuum truck, the fixed end frame 8 is installed on the rear wheel cover 18 of the vacuum truck, and the clamping plate assembly is installed on the front wheel frame 17 of the vacuum truck.

[0039] Specifically, the vacuum truck features a storage structure for cleaning heads 3 added to the storage box. The cleaning heads 3 are neatly installed on the sliding plate 5. During cleaning operations, the sliding plate 5 can be extended from the base, placing it outside the storage box for easy access to the appropriate cleaning head 3. This cleaning head storage structure is vertically arranged within the storage box, allowing all cleaning heads 3 to be placed at different heights without occupying excessive storage space at the bottom of the box. A warning label storage structure is also provided on the rear wheel cover 18. Since the warning labels 10 are hollow cones, multiple warning labels 10 can be stacked together and then inserted upside down into the first mounting hole on the movable end frame 11. When the warning label 10 needs to be retrieved, it is simply moved... The movable end frame 11 is rotated out to the outside of the vacuum truck, so that the warning label 10 is not obstructed by the vacuum truck's water tank when it is taken out. When the warning label 10 is not needed, the movable end frame 11 can be rotated to connect and fix it to the fixed end frame 8. In this way, the warning label 10 will be restricted by the vacuum truck's water tank, and the warning label 10 will not fall off accidentally. The movable end frame 11 is located inside the vacuum truck and does not affect the normal passage of the vacuum truck. A maintenance tool storage structure is set on the front wheel frame 17, and the placement rack 15 is set at an angle, so it is very convenient and quick to take out the maintenance tools 16. The placement rack 15 and the clamp assembly are stably connected to the frame, preventing the placement rack 15 and maintenance tools 16 from falling off accidentally during the vacuum truck's operation.

[0040] In one embodiment, the tool storage structure and the warning label storage structure can be placed on the front and rear wheels on the same side. This way, when the tool 16 is taken out, the warning label 10 is also taken out. After placing the warning label 10, the worker can start the repair directly. This can improve the worker's repair efficiency, avoid the worker having to walk around to take out the warning label 10 and the tool 16 multiple times, and reduce the worker's workload.

[0041] like Figures 1 to 3 As shown, the base includes a back plate 1, an upper groove plate 2, and a lower groove plate 7. The upper and lower ends of the back plate 1 are welded to one end of the upper groove plate 2 and one end of the lower groove plate 7, respectively. The other ends of the upper groove plate 2 and the lower groove plate 7 are respectively provided with sliding grooves. The upper groove plate 2 and the lower groove plate 7 are arranged in parallel. The upper and lower ends of the sliding plate 5 are slidably arranged in the sliding grooves of the upper groove plate 2 and the lower groove plate 7, respectively.

[0042] Preferably, the retainers 4 are staggered on the slide plate 5, and the bottom of the retainer 4 is provided with two first internal thread holes. The slide plate 5 is provided with through holes corresponding to the first internal thread holes, and the through holes and the first internal thread holes are connected by bolts.

[0043] Preferably, a push-pull handle 6 is provided at the end of the slide plate 5 near the opening of the storage box, and the push-pull handle 6 is bolted to the slide plate 5.

[0044] Specifically, in the cleaning head storage structure, the base is formed by welding or bolting the back plate 1 and the upper and lower groove plates 7. The back plate 1 and the lower groove plate 7 are fitted to the bottom and one side wall of the storage box, so that the cleaning head storage structure does not occupy too much space in the storage box. The slide plate 5 is slidably connected to the base through the sliding grooves of the upper and lower groove plates 7. Multiple fixing devices 4 are set on the slide plate 5, which are staggered. This allows more cleaning heads 3 to be placed horizontally on the slide plate 5. Each fixing device 4 has two first internal threaded holes at its bottom. Corresponding through holes are opened on the slide plate 5, and each fixing device 4 is bolted together. The two first internal threaded holes can determine the installation position of the fixing device 4 and avoid the fixing device from being bolted together. The installation position of 4 is inaccurate, which will cause interference between adjacent cleaning heads 3 when they are installed. In addition, the outer peripheral surface of the fixture 4 is provided with external threads. The cleaning head 3 is connected to the fixture 4 through the threaded connection. This not only ensures the connection area and the connection of the cleaning head 3, but also makes it easy for the vacuum truck to pick up and remove, reducing the difficulty of operation for workers. A push-pull handle 6 is provided on one end of the outer surface of the slide plate 5 near the outside of the garbage box, and a limit plate is provided on the other end of the slide plate 5. A limit block is provided on the back plate 1. When the cleaning head 3 is needed, the slide plate 5 is pulled out by pushing and pulling the handle 6. When the limit plate contacts the limit block, the slide plate 5 cannot slide outward, preventing the slide plate 5 and the cleaning head 3 on it from falling out of the garbage box. In existing vacuum trucks, the cleaning heads 3 are often simply stored in the toolbox or placed elsewhere on the truck. When using a cleaning head 3, one has to search for it, and in urgent cleaning situations, only a similar model of cleaning head 3 can be found, which greatly affects the cleaning effect. In the cleaning head storage structure protected in this application, the slide plate 5 is set vertically. When a cleaning head 3 needs to be retrieved, the slide plate 5 can be pulled out, making all cleaning heads 3 visible and convenient for workers to select the appropriate cleaning head 3 for cleaning operations. After use, the cleaning head 3 can be screwed back onto the slide plate 5 for easy reuse.

[0045] like Figures 4 to 7 As shown, the fixed end frame 8 is L-shaped and is bolted to the rear wheel cover 18. One end of the movable end frame 11 is rotatably connected to one end of the fixed end frame 8 through a pin 12. The fixed end frame 8 is provided with multiple fixing holes, and the movable end frame 11 is screwed with a locking pin 9. The lower end of the locking pin 9 is provided with a protrusion, and the locking pin 9 is set with the fixing holes corresponding to each other.

[0046] When the movable end frame 11 rotates to fit against the fixed end frame 8, the locking pin 9 rotates downward to engage the protrusion with the fixing hole.

[0047] Preferably, when the movable end frame 11 is in contact with the fixed end frame 8, the movable end frame 11 does not protrude from the rear wheel cover 18, and the distance between the movable end frame 11 and the water tank of the vacuum truck is less than the height of the warning sign 10.

[0048] Preferably, the side of the fixed end frame 8 is provided with multiple slots, and the side of the movable end frame 11 is provided with multiple plates. When the movable end frame 11 is attached to the fixed end frame 8, the slots and plates are inserted into each other in a corresponding manner.

[0049] Specifically, the warning label storage structure is installed on the rear side of the rear wheel cover 18. When the warning label 10 is not in use, the movable end frame 11 can be rotated to fit against the fixed end frame 8, thus storing the movable end frame 11 inside the vacuum truck without increasing its passage width. The movable end frame 11 has a double-layer plate structure, and two locking pins 9 are screwed onto it. The locking pins 9 penetrate the upper surface of the movable end frame 11, and a protrusion is provided at the end of the locking pin 9 located between the two layers. When the movable end frame 11 is fitted against the fixed end frame 8, the locking pin 9 is positioned directly above the fixing hole. By twisting the locking pin 9, the protrusion can be inserted into the fixing hole, thus locking the protrusion and fixing it in place. This prevents the movable end frame 11 from separating from the fixed end frame 8, and also prevents the warning label 10 from detaching from the movable end frame 11, as the vacuum truck's water tank restricts the upward movement of the warning label 10. When it is necessary to remove the warning label 10, the locking pin 9 can be twisted in the opposite direction, causing the protrusion to detach from the fixing hole. The movable end frame 11 can then rotate around the pin 12. When the movable end frame 11 rotates to the outside of the vacuum truck's water tank, the warning label 10 can be easily picked up from the movable end frame 11. The movable end frame 11 has a double-layer plate structure, while the fixed end frame 8 has a single-layer plate structure. When the movable end frame 11 and the fixed end frame 8 are attached, the fixed end frame 8 is inserted between the two layers of the movable end frame 11. Four slots and four plates are respectively provided on the contact sides of the two frames. Through the engagement of the slots and plates, it can be ensured that the movable end frame 11 and the fixed end frame 8 are properly attached. Finally, by turning the locking pin 9, the protrusion can be inserted into the fixing hole. This allows the movable end frame 11 to be accurately and quickly retracted into the inside of the vacuum truck, improving the efficiency of the warning label 10.

[0050] like Figure 8 and Figure 9 As shown, the clamp assembly includes a left clamp 13 and a right clamp 14, which are bolted together. The left clamp 13 and the right clamp 14 wrap around the outer periphery of the front wheel frame 17, and one side of the mounting bracket 15 is connected to all the right clamps 14.

[0051] Preferably, the placement rack 15 is disposed inside the front wheel frame 17.

[0052] Preferably, the placement rack 15 and the clamping plate assembly are arranged on different planes, and the axial extension direction of the second mounting hole does not intersect with the water tank of the vacuum truck.

[0053] Specifically, in the tool storage structure, the front wheel frame 17 is connected to the placement rack 15 via a clamping assembly. The clamping assembly consists of two clamping plates on the left and right sides, which clamp and fix the front wheel frame 17 from both sides. After the two clamping plates wrap around the front wheel frame 17 from both sides, they are connected by bolts. The clamping force of the bolts makes the clamping assembly and the front wheel frame 17 firmly connected, thus preventing the placement rack 15 from shaking during the operation of the vacuum truck. The front wheel frame 17 is set horizontally on the vacuum truck, and the clamping assembly is clamped and fixed to the front wheel frame 17, so the clamping assembly is also set horizontally. To facilitate easy access to the tool 16, the right clamping plate 14 is welded to the placement rack 15 to form a certain angle. Thus, when the tool storage structure is installed on the front wheel frame 17, the placement rack 15 is at a certain angle to the ground, and workers can directly access the tool 16 without interfering with the vacuum truck's water tank. In this way, as long as the placement rack 15 is set at a certain angle inside the front wheel frame 17, the maintenance tool storage structure can be placed on the placement rack 15 without protruding from the outer contour of the vacuum truck, making it convenient to take out the maintenance tool 16.

[0054] In summary, when performing cleaning operations, the modified vacuum truck is driven to the work site. The slide plate 5 is pulled from the base, and a suitable cleaning head 3 is installed on the water pipe. The maintenance tool 16 is then retrieved directly from the front wheel position. Simultaneously, the movable end frame 11 is rotated outwards from the rear wheel position, allowing the warning signs 10 to be lifted and a stack to be retrieved. These warning signs 10 are then placed at the work site to begin cleaning. After cleaning, the warning signs 10 are stacked together and inverted into the first mounting hole of the movable end frame 11. Next, the movable end frame 11 is rotated until it aligns with the fixed end frame 8. The locking pin 9 is then tightened, inserting the protrusion into the fixed hole. This completes the installation of the movable end frame 11. Once the fixed end frame 8 is fixedly connected, the warning sign 10 will not fall off the movable end frame 11, and the movable end frame 11 will not protrude from the outside of the vacuum truck and affect normal passage. Next, the maintenance tool 16 is directly inserted into the placement frame 15, and the head of the maintenance tool 16 is engaged with the second mounting hole. Because the handle of the maintenance tool 16 is too long, the maintenance tool 16 is not subjected to much vibration during the vacuum truck's operation, and the maintenance tool 16 will not fall off the placement frame 15. Finally, the used cleaning head 3 is installed back onto the fixing device 4, the slide plate 5 is returned to the storage box, and the slide plate 5 is fixed to the base. The fixing method can be conventional methods such as screws or magnetic attachments to prevent the slide plate 5 from accidentally sliding out during the vacuum truck's operation.

[0055] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
