[0001] The utility model relates to the technical field of car washers, in particular to a gantry type car washer suitable for operating in a low temperature environment. Background Art

[0002] With the advancement of technology, automatic car washers have become widely popular. Currently, the most common gantry car washers suitable for low-temperature environments include a gantry frame that can move on the ground, on which a roller brush and a top brush are arranged. The roller brush mainly washes the sides of the vehicle, while the top brush mainly washes the top of the vehicle.

[0003] In the existing gantry-type car washing machines suitable for operation in low-temperature environments, since the sides and tops of multiple vehicles need to be brushed during the car washing process, at least one roller brush and one top brush are arranged on each side of the gantry. The roller brush and the top brush are respectively responsible for brushing the sides and tops of the vehicles, and each roller brush needs to be driven to rotate by a motor alone. This requires that the entire car washing machine be installed with at least two roller brushes, two top brushes and four motors for driving the roller brushes or the top brushes to rotate, resulting in the structure of the entire car washing machine being too bloated and complicated. In addition, due to the large number of installed roller brushes, top brushes and motors, the manufacturing cost is high.

[0004] Secondly, in low temperature weather in winter (0° to -10°), the bristles on the drum brush and top brush of the gantry-type car washing machine suitable for operating in low temperature environments are prone to ice and freezing, resulting in the inability to carry out normal car washing operations, and the ability to adapt to the low temperature environment in winter is poor.

The roller brush swing motor 15 is installed on the connecting frame 16. The swing frame 17 is connected to the output shaft of the roller brush swing motor 15. The roller brush rotating motor 18 is arranged on the swing frame 17. The upper end of the roller brush 8 is connected to the roller brush rotating motor 18. The swing frame 17 is driven by the roller brush swing motor 15 to swing synchronously with the roller brush 8, so as to adjust the angle of the roller brush 8. The roller brush swing mechanism can swing the roller brush 8 to any angle between the horizontal state and the vertical state. By adjusting the angle of the roller brush 8, the roller brush 8 can be made to fit the outer surface of the vehicle at different angles. Among them, when the roller brush 8 is in a horizontal state, the roller brush 8 can be used as a top brush, which can fit the top of the vehicle and is used to brush the top of the vehicle; when the roller brush 8 is in a vertical state, the roller brush 8 can be used as a roller brush, which can fit the side of the vehicle and brush the side of the vehicle.

[0040] A fan swing mechanism is provided on both sides of the gantry 3, and a fan 11 is provided on the fan swing mechanism. The fan swing mechanism drives the fan 11 to swing in a vertical plane. The fan swing mechanism includes a fixed seat 22, a rotating shaft 23, and a fan swing motor 12. The fixed seat 22 is fixedly arranged on the gantry 3, and the rotating shaft 23 is rotatably connected to the fixed seat 22. One end of the rotating shaft 23 is connected to the fan swing motor 12.

[0041] In some embodiments of the present invention, the fan 11 is a vortex fan 11 .

[0042] Furthermore, both sides of the gantry 3 are respectively connected with an openable and closing water shield 13, the openable and closing water shield 13 is in an "L" shape, one side of the openable and closing water shield 13 is hinged to the gantry 3, and a waterproof heating strip is arranged on the inner side of the openable and closing water shield 13; an opening and closing driving component 14 is arranged between the openable and closing water shield 13 and the gantry 3, and the openable and closing water shield 13 is driven by the opening and closing driving component 14 to switch between an open state and a closed state; a first side panel 38 and a second side panel 39 corresponding to the openable and closing water shield 13 are arranged on the gantry 3.

[0043] When the retractable water shield 13 is in a closed state, the retractable water shield 13, the first side plate 38, and the second side plate 39 together enclose a heating and heat preservation space area, which is a rectangular closed space area, and the roller brush 8 is located in the heating and heat preservation space area. The waterproof heating strip is turned on when the temperature is below zero. After the waterproof heating strip is powered on, it heats the closed heating and heat preservation space area, so that the temperature in the heating and heat preservation space area is higher than zero degrees Celsius, thereby preventing the bristles on the roller brush 8 from freezing and becoming unusable.

[0044] When the openable water shield 13 is in the open state, an open area with one side open is formed between the openable water shield 13 and the first side plate and the second side plate. At this time, the existence of the openable water shield 13 can play a good water shielding function, preventing water from splashing toward the outside of the gantry-type car washing machine suitable for low-temperature environment operation during the car washing process. When the openable water shield 13 rotates from the open state to the closed state, the rotation angle of the openable water shield 13 is 90 degrees.

A heating device for heating water is provided in the clean water bucket 33, and an air compressor 37 is provided in the water tank 32. The high-pressure gas generated by the air compressor 37 drives the clean water in the clean water bucket 33 to spray out from the side nozzle 4. An insulation layer is provided on the outside of the clean water bucket 33. When the clean water in the clean water bucket 33 is heated by the heating device, the water temperature is controlled between 40 degrees and 45 degrees, which can prevent the water in the clean water bucket 33 from freezing and being unable to discharge in the low temperature in winter, and also prevent the pipes and clean water buckets from freezing and cracking due to ice. Insulation cotton is attached around the water tank 32, which can play a role in heat preservation in winter. Preferably, the heating power of the heating device is 15KW.

[0050] The water supply system also includes a sewage bucket 34, a filter 35, and a water pump 36. The filter 35 is arranged in the water tank 32. The water outlet of the water pump 36 is connected to the water inlet of the filter 35 through a pipe, and the water outlet of the filter 35 is connected to the sewage bucket 34 through a pipe. During the car washing process, the washed sewage will flow into the sump or trough near the floor 1 of the car washing area. The sewage in the sump or trough is extracted by the water pump 36, and after the large amount of sediment in the sewage is filtered by the filter 35, the sewage is passed into the sewage bucket 34 for storage; by collecting the car washing sewage, the pollution to the surrounding environment is reduced.

[0051] A thermometer is provided on the gantry 3, and the thermometer is used to detect the air temperature. When the air temperature is lower than a set temperature value, the waterproof heating strip and the heating device in the clean water bucket 33 will be turned on.
