[0021] The present invention will be further described below with reference to the accompanying drawings: As Figure 1 — Figure 6 shown, this embodiment provides a road dead corner cleaning device for a sanitation cleaning vehicle, including a main cleaning vehicle 1, a water pump 2, a water tank 3 and two transfer cleaning devices 4. The water pump 2 and the water tank 3 are both installed on the main cleaning vehicle 1, and the water pump 2 is connected to the water tank 3. The transfer cleaning device 4 includes a cleaning reference frame 41 and a cleaning deflection frame 42. The cleaning reference frame 41 is installed on the main cleaning vehicle 1, and the cleaning reference frame 41 is connected to the water pump 2, so that the water pump 2 supplies water to the cleaning reference frame 41. The cleaning reference frame 41 and the cleaning deflection frame 42 adsorb to each other. There are interconnected cleaning pipelines inside the cleaning reference frame 41 and the cleaning deflection frame 42. A plurality of nozzles 43 are arranged on the lower side of the cleaning pipelines. When the cleaning reference frame 41 and the cleaning deflection frame 42 adsorb to each other, a circular cleaning pipeline is formed. When the circular cleaning pipeline needs to pass through the column 5 of the middle guardrail, the cleaning reference frame 41 and the cleaning deflection frame 42 are first separated from each other until the circular cleaning pipeline slews around the column 5, and then the road surface around the column 5 is cleaned, eliminating dead corners. When the cleaning reference frame 41 and the cleaning deflection frame 42 adsorb to each other, the two cleaning pipelines are connected. Both sides of the cleaning deflection frame 42 and the cleaning reference frame 41 that are close to each other form two suction surfaces 45. The cleaning deflection frame 42 is provided with separation inclined planes 421 on both the inner part of the suction surface 45 located inside the circular cleaning pipeline and the outer part of the suction surface 45 located outside the circular cleaning pipeline. Each separation inclined plane 421 is inclined away from the suction surface 45. When the cleaning deflection frame 42 passes through the column 5, the separation inclined plane 421 slides along the column 5, so that the cleaning deflection frame 42 is separated from the cleaning reference frame 41. Until after the cleaning deflection frame 42 is separated from the cleaning reference frame 41 and slews around the column 5, the cleaning deflection frame 42 is separated from the cleaning reference frame 41 and closes again, so that the circular cleaning pipeline slews around the column 5 to clean the road surface under the column 5.

[0022] Specifically, the main cleaning vehicle 1 includes a cleaning vehicle frame 11, a cleaning power system 12, a sweeping system 13, a collection system 14, a collection hopper 15 and a dust cover 16. The cleaning power system 12, the sweeping system 13 and the collection system 14 are all installed on the cleaning vehicle frame 11. The sweeping system 13 and the collection system 14 are respectively in transmission connection with the cleaning power system 12. The cleaning power system 12 drives the sweeping system 13 to sweep. The collection hopper 15 is installed on the cleaning vehicle frame 11. The collection hopper 15 is located on the side of the collection system 14. The cleaning power system 12 drives the collection system 14 to act, sweeping the road garbage into the collection hopper 15. The dust cover 16 is installed on the cleaning vehicle frame 11. The dust cover 16 is located outside the sweeping system 13 and the collection system 14, reducing dust leakage.

[0023] Specifically, two universal wheels 111 and two walking wheels 112 are provided at the bottom of the cleaning vehicle frame 11 to realize the walking of the cleaning vehicle frame 11. For the convenience of walking, as a preferred embodiment, a walking motor for driving the walking wheels 112 to rotate is further provided on the cleaning vehicle frame 11.

[0024] Specifically, the cleaning power system 12 includes a cleaning motor 121 and a reduction box 122. The cleaning motor 121 is in transmission connection with the reduction box 122. A pulley is provided at the output end of the reduction box 122. The sweeping system 13 and the collection system 14 are both in transmission connection with the pulley through a synchronous belt. The cleaning motor 121 simultaneously realizes the operation of the sweeping system 13 and the collection system 14.

[0025] Specifically, the sweeping system 13 includes a sweeping synchronous shaft 131, two sweeping transmission shafts 132 and two sweeping arms 133. The two sweeping arms 133 are rotatably installed on the cleaning vehicle frame 11. Oil cylinders for controlling the opening and closing degree of the sweeping arms 133 are provided between the two sweeping arms 133 and the cleaning vehicle frame 11. The sweeping synchronous shaft 131 is rotatably installed on the cleaning vehicle frame 11. The two sweeping transmission shafts 132 are rotatably installed on the cleaning vehicle frame 11 and the axes of the two sweeping transmission shafts 132 are parallel to each other. The rotation axes of the two sweeping transmission shafts 132 are perpendicular to the rotation axis of the sweeping synchronous shaft 131. The two ends of the sweeping synchronous shaft 131 are respectively in transmission connection with the sweeping transmission shafts 132 through bevel gears. Sweeping shafts 134 are provided on both of the two sweeping arms 133. The two sweeping shafts 134 are respectively in transmission connection with the corresponding sweeping transmission shafts 132 through synchronous belts. The sweeping synchronous shaft 131 is in transmission connection with the cleaning power system 12 through a synchronous belt. The sweeping synchronous shaft 131 synchronously drives the two sweeping transmission shafts 132 to rotate, and further realizes the rotation of the two sweeping shafts 134 to realize sweeping.

[0026] Specifically, the collection system 14 includes a collection wheel. The conveying direction of the lower side of the collection wheel points to the collection hopper 15. The collection wheel is in transmission connection with the cleaning power system 12 to realize the rotation of the collection wheel and convey the dirt into the collection hopper 15.

[0027] Specifically, the cleaning reference frame 41 is slidably mounted on the main cleaning vehicle 1. Specifically, the cleaning reference frame 41 is provided with a guiding mounting post 412 that slidably cooperates with the main cleaning vehicle 1. A buffer spring is provided between the cleaning reference frame 41 and the main cleaning vehicle 1, and both ends of the buffer spring are respectively mounted on the cleaning reference frame 41 and the main cleaning vehicle 1, so that the cleaning reference frame 41 has a fitting property when cooperating with the upright post 5. The cleaning reference frame 41 is provided with avoidance inclined surfaces 411 on both the inner part of the annular cleaning pipeline and the outer part of the annular cleaning pipeline of each suction surface 45. Each avoidance inclined surface 411 is inclined away from the suction surface 45. After the avoidance inclined surface 411 contacts the upright post 5, under the guiding action of the avoidance inclined surface 411, the cleaning reference frame 41 and the cleaning deflection frame 42 are opened at the position of the suction surface 45 until the cleaning reference frame 41 and the cleaning deflection frame 42 surround the upright post 5, realizing that the cleaning reference frame 41 and the cleaning deflection frame 42 enclose the upright post 5, and then cleaning the road surface under the upright post 5. Subsequently, the cleaning reference frame 41 and the cleaning deflection frame 42 are opened at the position of another suction surface 45, so that the cleaning reference frame 41 and the cleaning deflection frame 42 are separated from the upright post 5.

[0028] Specifically, two water connectors 422 are provided on the cleaning deflection frame 42. Each water connector 422 forms a conical surface. The water connector 422 is communicated with the cleaning pipeline on the cleaning reference frame 41. The water connector 422 realizes the limit between the cleaning reference frame 41 and the cleaning deflection frame 42, so that the cleaning reference frame 41 and the cleaning deflection frame 42 will not move relative to each other due to different frictional forces between the cleaning reference frame 41 and the cleaning deflection frame 42 and the upright post 5 respectively. After one suction surface 45 of the cleaning reference frame 41 and the cleaning deflection frame 42 is opened, under the limitation of the water connector 422, the cleaning deflection frame 42 rotates around the cleaning reference frame 41. In order to further prevent the cleaning reference frame 41 and the cleaning deflection frame 42 from moving relative to each other, an auxiliary limit conical surface 423 is also provided on the cleaning deflection frame 42 to play a reference role in the rotation of the cleaning deflection frame 42 when the cleaning reference frame 41 and the cleaning deflection frame 42 are opened.

[0029] In order to ensure that the cleaning reference frame 41 and the cleaning deflection frame 42 can close again after being opened relative to each other, permanent magnets are provided on both the avoidance inclined surface 411 and the separation inclined surface 421, so that the avoidance inclined surface 411 and the separation inclined surface 421 can attract the upright post 5 of the guardrail when the cleaning reference frame 41 and the cleaning deflection frame 42 are separated from each other, ensuring that the cleaning reference frame 41 and the cleaning deflection frame 42 can close smoothly after being opened.

[0030] When the cleaning frame 11 is moving, the cleaning reference frame 41 can supply water continuously. However, there may be a situation of water splashing when supplying water continuously. If the road surface does not allow water splashing to ensure pedestrian passage, water can also be supplied for cleaning after the cleaning reference frame 41 and the cleaning deflection frame 42 enclose the column 5. In order to reduce water leakage, a sealing ring is provided at the position where the cleaning reference frame 41 is adapted to the water joint 422.
