Description
Technical Field
The invention relates to the field of environmental sanitation equipment, in particular to a cleaning vehicle for washing, sweeping and dry sweeping.
Background
Due to the advantages of high working efficiency, good sweeping effect, manpower and cost saving, the sweeper (also called a cleaning vehicle or a sweeping machine) is widely used for cleaning the places such as roads, factories and scenic spots. The sweeper can be classified into a pure suction type sweeper, a pure sweeping type sweeper, a suction sweeping type sweeper, a washing sweeping type sweeper and the like according to the working mode of the sweeper. The washing and sweeping vehicle washes the road surface through high-pressure water spraying equipment, the washed road surface is swept by a high-speed disc brush, and the swept garbage and sewage are sucked into a garbage can on the vehicle by a middle-mounted or rear-mounted negative pressure sucking disc.
At present, the washing and sweeping vehicle on the market can not normally operate in cold places in winter. One reason is that the water tank of the washing and sweeping vehicle has limited capacity, water needs to be added after the water tank is used up, and water of the outdoor fire hydrant is frozen in winter, so that the washing and sweeping vehicle cannot be added with water. Another reason is that the low temperature in winter can cause the water pump, valve and pipeline of the washing and sweeping vehicle to be frozen or even frozen and cracked, so that the washing and sweeping vehicle cannot be used normally. The other important reason is that the water sprayed on the ground by the washing and sweeping vehicle can be frozen in winter, and a large amount of dust can be generated to pollute the environment if the floor is only swept without spraying water. Therefore, the washing and sweeping vehicle is often idle in winter, resulting in low equipment utilization rate and waste of resources.
In order to overcome the difficulties, one method is to add a set of heating equipment to the waterway pipeline on the washing and sweeping vehicle. Patent document CN205242335U discloses an all-weather washing and sweeping vehicle, in which a heating device is laid on the outer surface of the water outlet pipeline along the extending direction of the water outlet pipeline, and an insulating layer is arranged to wrap the heating device. Therefore, the heating device is started under the low-temperature condition in winter, the water path system can be ensured not to be frozen, and the water sprayed on the road surface can be sucked back, so that no accumulated water exists on the road surface. However, this solution requires modification of the water outlet pipeline and addition of a heating device, which increases the manufacturing cost and increases the energy consumption.
Another method is to provide a dry sweeping function for a washing and sweeping vehicle, and patent document CN207878357U discloses a car body and a sweeping vehicle for both washing and sweeping and dust collection. The carriage is provided with a dry sweeping dust cavity, a wet sweeping garbage cavity and a dust storage cavity, the dry sweeping dust cavity and the wet sweeping garbage cavity are controlled to be communicated or not through a valve cavity, and the dry sweeping dust cavity is communicated with the dust storage cavity through a connecting cavity. The wall of the dry sweeping dust cavity is provided with a water inlet and a water outlet connected with the nozzle, and the outlet of the dust storage cavity is connected with a detachable sealing plate. When the sweeper is used as a dust collection vehicle, the water inlet of the dry sweeping dust cavity is sealed, the filter element is arranged in the cavity, and the communication between the dry sweeping dust cavity and the wet sweeping dustbin is disconnected. When the sweeper is used as a washing sweeper, the filter element in the dust dry sweeping cavity is detached, a pipeline system such as a water pipe, a nozzle and the like is installed, and a sealing plate is installed at the end part of the dust storage cavity. At the moment, the dry-sweeping dust cavity, the connecting cavity and the dust storage cavity form a closed cavity which can be used as a clean water tank of the washing and sweeping vehicle. The sweeper realizes cleaning and dust collection by disassembling and replacing part of the components, so that the universality of the carriage is increased, and the utilization rate of the sweeper is improved. However, this solution has several major drawbacks. Firstly, although the dry cleaning dust chamber and the dust storage chamber can be used as water tanks in the cleaning mode, complex and careful disassembly and assembly work is required, and extremely high requirements are provided for the sealing performance of the valve chamber, the water inlet and the sealing plate, so that the implementation cost is greatly increased. Secondly, the common compartment actually limits the capacity of the water tank, and further limits the cruising ability of the sweeper in the washing and sweeping mode. Thirdly, the inlet at one end of the suction nozzle of the sweeper for washing and sweeping is positioned below the bottom plate of the carriage body, the outlet at one end of the suction nozzle is positioned in the wet sweeping dustbin, and the communication pipeline in the middle passes through the connecting cavity of the dry sweeping dust cavity and the dust storage cavity. When the sweeper works in a dust collection mode, the connecting cavity is closed, and the suction nozzle cannot form a closed air path with the fan. This means that an additional set of suction nozzles must be provided for suction, which increases the structural complexity and the manufacturing costs. Finally, when the dust collection and cleaning share one compartment, a lot of garbage and dust enter the dry cleaning dust chamber and the dust storage chamber in the dust collection mode, so that the space becomes dirty. If the space is directly used as a clean water tank in a washing and sweeping mode, water is polluted, and a water pump and a pipeline are abraded, blocked and even damaged. If the space is cleaned prior to the scrubbing mode, the workload is greatly increased, and the work efficiency is reduced.
Further, patent document CN201420249Y discloses an all-weather road sweeper, which also shares a dust removing box and a clean water box, thereby having dual functions of washing and dry sweeping. Like the CN207878357U patent, the sweeper has the disadvantages of complex disassembly and replacement, high requirement on sealing performance, limited water tank capacity, dust pollution of the clean water tank, and the like.

Further, the air path flow direction of the washing and sweeping mode is as follows: suction nozzle 501 → suction pipe 503 → dustbin 7 → wet sweeping filter screen 603 → blower inlet 505 → blower 504 → blower outlet 506, wherein the sweeping mode is suitable for non-low temperature environmental conditions.
When the sweeper is operating in dry sweeping mode, the water spray device 3 is not in operation and must be fitted with a dry sweeping filter cartridge 602. Before operation, the water tank 301 is drained to reduce the load of the vehicle, or the water tank 301 is kept when no water is required to be drained, and the dry-wet switching valve 604 is switched to the vertical position, as shown in fig. 1, and when operation, the sweeping disk 401 is rotated to sweep up dust and debris on the floor and collect them back to the suction nozzle 501. The fan 504 creates a negative pressure environment in the dustbin 7 by sucking air from the dustbin 7 and discharging air from the fan outlet 506, and dust and garbage are sucked into the dustbin 7 through the suction nozzle 501 and the suction duct 503 by the external air pressure. Larger garbage falls into the garbage can 7 through gravity settling and blocking of a dry-sweeping filter screen 601; dust and small particulate debris are filtered at the dry sweep filter cartridge 602. The whole dry sweeping mode flow realizes the cleaning of the ground and the collection of dust and garbage.
Further, the air path flow direction in the dry cleaning mode is: suction nozzle 501 → suction duct 503 → dustbin 7 → dry sweeping filter screen 601 → dry sweeping filter cartridge 602 → blower inlet 505 → blower 504 → blower outlet 506. Under the dry sweeping mode of the sweeper, the water tank 301 can be used not only under the low-temperature environmental condition, but also under the non-low-temperature environmental condition, for example, when the water in the water tank is exhausted and the washing and sweeping mode cannot be adopted, so that the utilization rate of the sweeper is further improved.
In the dry sweeping mode, a dust cover may be added above the sweeping disk 401 to prevent dust from spreading around and polluting the air and environment during operation.
At the beginning of the cleaning operation, the push rod driving device 403 drives the push rod 402 to open the cleaning plate 401 to the outside of both sides of the vehicle body, so as to expand the cleaning width as much as possible and enhance the cleaning effect. After the cleaning work is finished, the push rod driving device 403 drives the push rod 402 to retract the sweeping disk 401 to the inner parts of the two sides of the vehicle body, so that the probability that the sweeping disk 401 collides with an obstacle when the vehicle runs is reduced. The opening and retraction of the sweeping disk 401 can be controlled by a person in the cockpit 2 or can be automatically performed by the sweeper according to the environment and task.
At the beginning of cleaning, the suction nozzle lifting device 502 lowers the suction nozzle 501 from a position close to the chassis 1 to a height suitable for suction work, so as to expand the suction range as much as possible and enhance the cleaning effect. After the cleaning work is finished, the suction nozzle elevating device 502 elevates the suction nozzle 501 from the suction work level to a position close to the chassis 1 to reduce the possibility of collision of the suction nozzle 501 with an obstacle while the vehicle is running. The lowering and raising of the suction nozzle 501 can be controlled by a person in the cockpit 2 or can be automatically performed by a sweeper according to the environment and task.
The cabin 2 may be manned or unmanned. When the driver cabin 2 has a person, the person is used as a driver to control the operation of the sweeper such as running, steering, stopping and the like, the sweeper is manually controlled to perform the tasks of spraying water, cleaning, sucking and the like, and the sweeper is manually controlled to dump garbage from the garbage can 7 to a specified place. When the cab 2 is not occupied, the sweeper is in a state of automatically driving and automatically executing a cleaning task, the sweeper is provided with a sensor, a controller and a communication system, the sensor is used for sensing surrounding environment information and state information of the sweeper, and the controller controls the sweeper to automatically carry out operations such as driving, steering and parking according to the environment information and the state information acquired by the sensor and a remote instruction received by a preset program or the communication system, and automatically executes tasks such as water spraying, cleaning, sucking and garbage dumping.
Before dumping the garbage, the garbage can 7 opens the sewage outlet 703 to discharge the sewage in the garbage can 7, and then the supporting rod 702 lifts the front end of the garbage can 7 so as to dump the garbage in the can. The fan inlet 505 is fixedly connected to the front end of the dustbin 7, and when the front end of the dustbin 7 is lifted, the fan inlet 505 is also separated from the fan 504. When the dustbin 7 returns to the normal horizontal position, the fan inlet 505 is attached to the fan 504, and a certain pressure exists in the contact between the fan inlet and the fan 504, and the sealing performance is maintained through the sealing rubber strip.
The power system of the sweeper truck may be electric or internal combustion. The electric power system provides power from the electric motor, and the electric motor is powered by the battery system. The power provided by the internal combustion type power system is from an engine, the engine is powered by a fuel system, meanwhile, the water pump 302, the push rod 402 and other devices are still driven by a motor, the electric energy required by the motor is from a generator connected with the engine, and the generator is provided with a small-capacity battery to realize standby power supply.
