Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a sweeper vehicle operation water drainage system and a sweeper vehicle. Background Technology

[0002] A sweeper truck, also known as a street sweeper, is an integrated garbage sweeper that combines sweeping and vacuuming. It has advantages such as high work efficiency, low cleaning cost, good cleaning effect, high safety performance, and high economic return. It has been widely used in the cleaning of roads in cities of all sizes. Sweepers are equipped with a water spraying function to prevent dust from causing secondary environmental pollution during the sweeping process. Two rotating brushes are installed at the front of the vehicle. When the vehicle moves forward, the rotating brushes at the front will bring the garbage and sand on the ground to the middle of the vehicle through rotation. Then, the negative pressure suction head of the vehicle will suck the garbage and sand into the waste collection box on the vehicle.

[0003] When the temperature drops below 0°C in winter, the water system for spraying and dust suppression on a sweeper truck (including water valves, water pumps, water tanks, and water pipes) needs to be completely drained to prevent damage to components due to freezing and expansion. Generally, sweepers use compressed air to supply water to the system, closing the water tank outlet and opening the spray nozzles to ensure no large amount of water remains in the system.

[0004] However, many sweepers do not have compressed air pumps, especially small sweepers. Without compressed air, water may accumulate in certain sections of the spraying and dust suppression water circuits when they are horizontal or the outlets are facing upwards. This makes it difficult to manually drain the entire water circuit. In addition, the water circuits are prone to freezing and damage when the temperature drops below 0°C in winter.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 like Figure 1 As shown, this embodiment includes a water tank 10, a water path 20, a connecting component 30, a suction pipe 40, a trash can 50, and a negative pressure fan 60. The water tank 10 is a non-sealed water tank; the inlet of the water path 20 is connected to the water tank 10; the connecting component 30 connects the water path 20 to the suction pipe 40; the exhaust port of the suction pipe 40 is connected to the trash can 50; and the suction port of the negative pressure fan 60 is connected to the trash can 50. In this embodiment, the water path 20 is equipped with a main water valve 21 for controlling the flow rate, and a humidity sensor 22 is installed inside the water path 20 for detecting the humidity within the water path 20. The connecting component 30 is a straight connecting pipe located at the rear of the water path 20 and the suction pipe 40, used to connect the water path 20 and the suction pipe 30; in this embodiment, the water path 20 is provided with a connecting port that connects to the inlet end of the straight connecting pipe.

[0021] The outlet end of the connecting straight pipe is connected to the vacuum pipe 40; in this embodiment, the vacuum pipe 40 is provided with a through hole that is connected to the outlet end of the connecting straight pipe.

[0022] The outlet of the water channel 20 is connected to a first electric ball valve 32, and the first electric ball valve 32 is connected to a spray head 33; in this embodiment, the spray head 33 can both spray and suppress dust.

[0023] A second electric ball valve 41 is provided on the suction pipe 40 between the suction port of the suction pipe 40 and the connecting component 30; the second electric ball valve 41 can control the suction pipe to perform suction or stop suction.

[0024] In this embodiment, a negative pressure fan 60 is installed on the garbage bin 50; a filter screen 61 is provided between the suction inlet of the negative pressure fan 60 and the garbage bin 50; the negative pressure fan 60 is detachably connected to the garbage bin 50; thus, when the garbage bin 50 is full of garbage, the garbage bin 50 can be detached from the negative pressure fan 60 to achieve cleaning inside the garbage bin 50; at the same time, the filter screen 61 can also be removed for cleaning.

[0025] In addition, the connecting component 30 is provided with an electric ball valve 31 for controlling the connection between the suction pipe 40 and the water passage 20. In this embodiment, the electric ball valve 31 is provided on the connecting straight pipe.

[0026] In this embodiment, the water circuit 20 is shared by the water circuits for spraying and dust suppression.

[0027] The working principle of this utility model is as follows: When the temperature drops below 0°C in winter, after the sweeper has finished cleaning and the water in the tank has been drained by opening the main water valve 21, the water circuit 20 needs to be drained. First, the first electric ball valve 32 and the second electric ball valve 41 are closed, and the electric ball valve 31 is opened. Then, the negative pressure fan 60 runs to create negative pressure in the water circuit 20. By closing the first electric ball valve 32 and the second electric ball valve 41, the negative pressure in the water circuit 20 is increased, and the negative pressure forces the water in the water circuit 20 into the garbage bin 50 through the connecting straight pipe and the suction pipe 40, and then drains the water from the garbage bin 50. At the same time, the humidity sensor 22 can detect the drainage status of the water in the water circuit 20, and then control the running time of the negative pressure fan to achieve the drainage of the water in the water circuit 20. This prevents the water circuit from being easily damaged by freezing when the temperature drops below 0°C in winter.

[0028] Example 2 like Figure 2As shown, the difference between this embodiment and embodiment 1 is that: the connecting component 30 is a three-way pipe, the first end of the three-way pipe is connected to the water outlet of the water passage 20, the second end of the three-way pipe is connected to the middle of the suction pipe 40, the third end of the three-way pipe is connected to a first electric ball valve 32, and the first electric ball valve 32 is connected to a spray head 33; a second electric ball valve 41 is provided on the suction pipe 40 between the suction port of the suction pipe 40 and the second end of the three-way pipe.

[0029] In this embodiment, the middle part of the suction pipe 40 is the position between the suction port and the exhaust port in the suction pipe 40.

[0030] In this embodiment, the suction pipe 40 is provided with a through hole that communicates with the second end of the three-way pipe.

[0031] In addition, the connecting component 30 is provided with an electric ball valve 31 for controlling the connection between the suction pipe 40 and the water channel 20. In this embodiment, the electric ball valve 31 is located on the second end of the three-way pipe.

[0032] The working principle of this utility model is as follows: When the temperature drops below 0°C in winter, after the sweeper has finished cleaning and the water in the water tank has been drained by opening the main water valve 21, the water circuit 20 needs to be emptied. The negative pressure fan 60 runs, creating negative pressure in the water circuit 20. This negative pressure forces the water in the water circuit 20 through the T-pipe and suction pipe 40 into the garbage bin 50, and then drains the water from the garbage bin 50. At the same time, the humidity sensor 22 can detect the water drainage status in the water circuit 20, thereby controlling the running time of the negative pressure fan to achieve the emptying of the water in the water circuit 20. This prevents the water circuit from freezing and being damaged when the temperature drops below 0°C in winter.

[0033] Example 3 like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that the connecting component 30 includes at least two connected T-pipes, wherein the first ends of the at least two T-pipes are respectively connected to the water outlet of the water path 20 and the dust suction port of the dust suction pipe 40.

[0034] The second ends of at least two T-joints are interconnected; the third ends of at least two T-joints are respectively connected to a first electric ball valve 32 and a second electric ball valve 41, the first electric ball valve 32 is connected to a spray head 33, and the second electric ball valve 41 is connected to a vacuum head 45.

[0035] The working principle of this utility model is as follows: When the temperature drops below 0°C in winter, after the sweeper has finished cleaning and the water in the tank has been drained by opening the main water valve 21, the water circuit 20 needs to be drained. First, the first electric ball valve 32 and the second electric ball valve 41 are closed, and the electric ball valve 31 is opened. Then, the negative pressure fan 60 runs to create negative pressure in the water circuit 20. By closing the first electric ball valve 32 and the second electric ball valve 41, the negative pressure in the water circuit 20 is increased, and the negative pressure forces the water in the water circuit 20 into the garbage bin 50 through at least two T-joints and the suction pipe 40, and then drains the water from the garbage bin 50. At the same time, the humidity sensor 22 can detect the drainage status of the water in the water circuit 20, and then control the running time of the negative pressure fan to achieve the drainage of the water in the water circuit 20. This prevents the water circuit from being easily damaged by freezing when the temperature drops below 0°C in winter.

[0036] Example 4 like Figure 4 As shown, the difference between this embodiment and any of the above embodiments is that: a dust suppression water channel 70 is also connected to the water channel 20, and a dust suppression electric ball valve 71 is provided on the dust suppression water channel 70; thus, through the dust suppression water channel 70 and the dust suppression electric ball valve 71, this utility model can simultaneously spray for dust suppression.

[0037] When the temperature drops below 0°C in winter, after the sweeper has finished sweeping and the water in the tank has been drained by opening the main water valve 21, the water circuit 20 needs to be drained. First, the first electric ball valve 32, the second electric ball valve 41, and the dust suppression electric ball valve 71 are closed, and electric ball valve 31 is opened. Then, the negative pressure fan 60 operates, creating negative pressure in the water circuit 20 and the dust suppression water circuit 70. By closing the first electric ball valve 32, the second electric ball valve 41, and the dust suppression electric ball valve 71, the water circuit 20... The negative pressure in the dust suppression water path 70 is increased, which forces the water in the water path 20 and the dust suppression water path 70 into the garbage bin 50 through the connecting component and the suction pipe 40, and then drains the water from the garbage bin 50. At the same time, the humidity sensor 22 can detect the drainage status of the water in the water path 20, and thus control the running time of the negative pressure fan to achieve the drainage of the water in the water path 20. This prevents the water path from freezing and being damaged when the temperature drops below 0°C in winter.
