[0028] See also Figure 1 The utility model provides a water tank. The water tank comprises a tank body 1, a clean water tank 3 with a variable volume installed in the tank body 1, and a sewage cavity 5 formed in the remaining space inside the tank body 1. The space of the sewage cavity 5 is all the remaining space in the tank body 1 except the volume of the clean water tank 3.

[0029] See also Figure 2 and Figure 3The clean water tank 3 includes a soft water-carrying bag 31, a foldable telescopic frame 33, a fixed plate 35 and a pull plate 37. The fixed plate 35 is fixedly connected to the side wall of the box body 1, and the pull plate 37 is arranged opposite to the fixed plate 35. One end of the foldable telescopic frame 33 is connected to the fixed plate 35, and the other end is connected to the pull plate 37. The peripheral side of the pull plate 37 is fixedly connected to the inner wall of the water-carrying bag 31. The water-carrying bag 31 is fixed to the side wall of the box body 1 and wraps the fixed plate 35, the foldable telescopic frame 33 and the pull plate 37 in the water-carrying space formed therein. The water-carrying bag 31 is connected to a water inlet pipe. The water-carrying bag 31 can be opened along the telescopic track of the foldable telescopic frame 33 under water supply. The sewage entering the garbage cavity of the cleaning vehicle compartment enters the sewage cavity 5. When the sewage cavity 5 is loaded with water, the water-carrying bag 31 is compressed along the telescopic track of the foldable telescopic frame 33 during the squeezing process. During the cleaning process of the sanitation vehicle, the clean water in the clean water tank 3 is sprayed onto the road surface through the water spray pipe, and the suction nozzle sucks up the garbage through the pipe, and the sewage that enters the garbage chamber 101 with the garbage will flow into the sewage chamber. As the amount of water in the clean water tank 3 decreases during the operation, the sewage entering the sewage chamber 5 slowly increases. Under the squeezing of the sewage in the sewage chamber 5, the clean water tank 3 itself can be folded into a state with the smallest volume. When the clean water in the clean water tank 3 is gradually consumed and the water in the sewage chamber 5 gradually increases, the sewage will gradually compress the folded clean water tank 3 until the clean water is completely consumed, the sewage is completely recovered, and the sewage is discharged after one cleaning is completed. Compared with the traditional water tank, this foldable clean water tank 3 makes full use of the effective volume in the box body 1. Under the same chassis, the overall box body 1 is smaller in volume, and there is enough space to increase the volume of the box body 1, so that the whole vehicle operation time is longer. After that, clean water is again filled into the clean water tank 3, and the clean water tank 3 gradually expands to the maximum capacity (the sewage chamber is empty at this time) along the movement trajectory of the foldable telescopic frame 33 as the amount of water increases. It can be understood that the foldability of the foldable telescopic frame 33 is used to achieve the change of the volume of the clean water tank 3, so that the water-carrying bag 31 is affected by the telescopic trajectory of the foldable telescopic frame 33 during the carding and squeezing process, so that the water-carrying bag 31 can move along the trajectory of the foldable telescopic frame 33, and the contraction of the water-carrying bag 31 is more controllable.

[0030] Therefore, by installing the clean water tank 3 in the box body 1, and the sewage chamber 5 is formed in the remaining space inside the box body 1, and the clean water tank 3 is configured as a soft water-carrying bag 31, according to the variability of the volume of the water-carrying bag 31, a mutually complementary relationship is formed with the space of the sewage chamber 5, and the foldable telescopic frame 33 installed in the water-carrying bag 31 enables the water-carrying bag 31 to be extended and retracted along a predetermined trajectory under the action of the foldable telescopic frame 33, the contraction of the water-carrying bag 31 is better controllable, and it is more flexible and reliable during the expansion and compression process.

[0031] Furthermore, the foldable telescopic frame 33 includes a plurality of connecting rods, which are rotatably connected to form a scissor-type structure, and the scissor-type structure supports the water bag 31, so that the water bag 31 can be extended and retracted under its predetermined trajectory and under the action of water inflow and external squeezing.

[0032] In one embodiment, the upper and lower fulcrums at both ends of the foldable telescopic frame 33 can be hinged on the fixed plate 35 and the pull plate 37. The upper and lower fulcrums are both hinged to achieve the folding and telescopic movement of the foldable telescopic frame 33.

[0033] In another embodiment, the lower fulcrum at one end of the foldable telescopic frame 33 is rotatably connected to the pull plate 37, the upper fulcrum at one end of the foldable telescopic frame 33 is rollably connected to the pull plate 37, the upper fulcrum at the other end of the foldable telescopic frame 33 is rotatably connected to the fixed plate 35, and the lower fulcrum at the other end of the foldable telescopic frame 33 is rollably connected to the fixed plate 35. The fulcrum at one end of the foldable telescopic frame 33 is rollably connected to the fixed plate 35 and the pull plate 37. When the foldable telescopic frame 33 is telescopically moved, the rolling connection of the two fulcrums can reduce the movement friction of the structure and increase the flexibility. Specifically, rollers 38 are respectively installed on the lower fulcrum and the upper fulcrum at both ends of the foldable telescopic frame 33, and the pull plate 37 and the fixed plate 35 are provided with slide grooves 39, and the rollers 38 are embedded in the slide grooves 39 and move along the slide grooves 39. The slide groove 39 is opened vertically, and the foldable telescopic frame 33 moves up and down along the slide groove 39 as the telescopic length of the foldable telescopic frame 33 changes. The roller 38 is arranged to reduce the friction of the foldable telescopic frame 33. When the external force is small, the foldable telescopic frame 33 can also be pushed to be squeezed and folded.

[0034] The two foldable telescopic frames 33 are arranged at a relative interval, and the ends of the two ends of the two foldable telescopic frames 33 are rotatably connected by an assembly rod. The two foldable telescopic frames 33 can rotate around the assembly rod at the same time. It can be understood that the two foldable telescopic frames 33 are arranged at the same time to improve the structural strength.

[0035] In detail, each of the foldable telescopic frames 33 includes four rotatably connected connecting rods, namely a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod. The middle parts of the first connecting rod and the second connecting rod, the third connecting rod and the fourth connecting rod are hinged in pairs, and the ends of the second connecting rod and the fourth connecting rod, the first connecting rod and the third connecting rod are hinged.

[0036] Furthermore, the water-carrying bag 31 is made of a flexible material, and specifically, the water-carrying bag 31 is made of rubber. Since rubber has the ability to deform, the water-carrying bag 31 made of rubber can present different shapes under the action of external force, so that the volume of the water-carrying bag 31 can be changed. Specifically, the four sides of the pull plate 37 inside the water-carrying bag 31 are fixedly connected to the inner wall of the water-carrying bag 31, so that when the foldable telescopic frame 33 pushes and pulls the water-carrying bag 31, the water-carrying bag 31 can be better expanded and contracted with it.

[0037] See also Figure 1 and Figure 2 The utility model also provides a sanitation sweeper compartment, which includes a water tank, a garbage chamber 101, a clean water pipe 103, a sewage pipe 105 and a suction pipe 107. The garbage chamber 101 is formed in the remaining space in the compartment isolated by the water tank. The clean water pipe 103 passes through the fixed plate 35 and is connected to the inside of the clean water tank 3 for connecting an external water supply device to supply water to the clean water tank 3. The sewage pipe 105 is connected to the sewage chamber 5 for discharging sewage therein. The suction pipe 107 is connected to the garbage chamber 101, and the sewage chamber 5 is connected to the garbage chamber 101. The suction nozzle of the sweeper is connected to the garbage chamber 101 through the suction pipe 107, and the garbage is sucked into the garbage chamber 101. The sewage sucked into the garbage chamber 101 is then discharged into the sewage chamber 5.

[0038] The box body 1 includes a top plate 11, a bottom plate 13, a side plate 15 and a partition plate 17. The top plate 11 and the bottom plate 13 are arranged opposite to each other. The top plate 11 and / or the partition plate 17 are provided with a plurality of water filtering holes penetrating the upper and lower surfaces thereof. The sewage chamber 5 is connected with the garbage chamber 101 through the water filtering holes. The fixing plate 35 is fixed on the side plate 15. The sewage in the garbage chamber 101 flows into the sewage chamber 5 through the water filtering holes to separate the solid and liquid of the garbage. After the clean water flows out to wash the ground, the amount of sewage will become less and less. At the same time, the more sewage there is in the sewage chamber 5, the more sewage will squeeze the water-carrying bag 31 under the condition of gradual increase. In this way, the volume of the water-carrying bag 31 is reduced, and the sewage chamber 5 is gradually increased. The change in the volume of the clean water tank 3 will not occupy the space inside the box body 1.

[0039] Wherein, the partition 17 is tilted, and the angle α between the partition 17 and the horizontal plane is 40-50°. That is, the angle between the partition 17 and the horizontal plane can be 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49° or 50°. Preferably, in this embodiment, the angle between the partition 17 and the horizontal plane is 47°. Garbage, stones, sewage, etc. are sucked into the garbage chamber 101 through the suction pipe 107. The garbage quickly settles on the right side of the top plate 11 or the partition 17 by inertia. The sewage enters the sewage chamber through the water filter hole, and the garbage, stones, etc. are always above the right side of the second side. The sucked garbage, stones, and sewage are effectively classified and processed, and solid garbage is prevented from entering the sewage chamber, which causes wear on the flexible water bag of the clean water tank 3, increases the service life of the clean water tank 3, and reduces the maintenance cost of the clean water tank 3.

[0040] Further, the top plate 11 and / or the partition 17 are filter nets. That is, the top plate 11 and the partition 17 are both filter nets, or the top plate 11 or the partition 17 is a filter net. Preferably, in this embodiment, the top plate 11 and the partition 17 are both filter nets, so that the sewage in the garbage chamber 101 can flow into the sewage chamber 5 as quickly as possible.

[0041] The water tank and the carriage of the sanitation sweeper provided by the utility model are achieved by installing the clean water tank 3 in the box body 1, and the sewage chamber 5 is formed in the remaining space inside the box body 1, and the clean water tank 3 is configured as a soft water-carrying bag 31. According to the variability of the volume of the water-carrying bag 31, a complementary relationship is formed with the space of the sewage chamber 5. The foldable telescopic frame 33 installed in the water-carrying bag 31 enables the water-carrying bag 31 to be extended and retracted along a predetermined trajectory under the action of the foldable telescopic frame 33. The contraction of the water-carrying bag 31 is better controllable, and it is more flexible and reliable during the expansion and compression process.
