[0002] Rail transit elevated stations refer to rail transit stations located above the ground, mainly used for urban rail transit such as subways, light rails or urban express trains. Compared with ground stations and underground stations, elevated stations have their own unique characteristics and advantages. Rail transit elevated stations generally adopt lightweight designs and materials, especially lightweight ceilings, in order to save construction costs and reduce structural weight.

[0003] Lightweight ceilings can reduce their own weight and have good thermal insulation properties, but when it snows, as the thickness of the snow increases, it creates additional loads on the supporting structure and generates great pressure, posing the risk of ceiling rupture and collapse.

[0025] According to an embodiment of the utility model, an automatic snow removal device for the roof of a rail transit elevated station is provided.

[0026] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-Figure 6 As shown, the automatic snow removal device for the roof of an elevated rail transit station according to an embodiment of the utility model includes a base plate 1, a fixed sleeve 2 is provided at one end of the top of the base plate 1, a fixed support column 3 is provided at the other end of the top of the base plate 1, a rotating lifting mechanism 4 is provided inside the top of the fixed sleeve 2, a trigger mechanism 5 is provided at the top of the rotating lifting mechanism 4, and a connecting column 6 is provided at the top of the trigger mechanism 5; a fixed cylinder 7 is provided at the top of the fixed support column 3 and the connecting column 6, a rotating shaft 8 is provided inside the fixed cylinder 7, a plurality of openings 9 are opened on the outside of the fixed cylinder 7, a plurality of support rods 10 inserted into the openings 9 are provided on the outside of the rotating shaft 8, and a rail transit elevated station roof 11 is provided on the top of the support rod 10.

[0027] With the help of the above-mentioned technical scheme of the utility model, the utility model can automatically identify whether the snow accumulation on the ceiling has reached a critical weight, and can increase the inclination angle of the ceiling by starting the rotating lifting mechanism 4. At the same time, vibration is generated during the lifting process to achieve the snow removal effect without manual intervention, thereby improving the snow removal efficiency and response speed, greatly improving the safety of the station, and being able to cope with continuous and high-intensity snowfall.

[0028] In one embodiment, for the above-mentioned rotary lifting mechanism 4, the rotary lifting mechanism 4 includes a rotary lifting motor 401 arranged inside the fixed sleeve 2, a rotary rod 402 is arranged at the top of the output shaft of the rotary lifting motor 401, a vibration assembly 403 is arranged at the top of the rotary rod 402, a protective shell 404 is arranged on the outside of the vibration assembly 403, and a connecting block 405 that penetrates the top of the protective shell 404 and is connected to the trigger mechanism 5 is arranged at the top of the vibration assembly 403; the vibration assembly 403 is composed of two groups of relatively arranged disc ratchets 4031, and the disc ratchet 4031 located at the bottom is fixedly connected to the rotary rod 402, and the disc ratchet 4031 located at the top is movably connected to the connecting block 405. In addition, in specific applications, a damping bearing is arranged between the connecting block 405 and the protective shell 404, so that under the drive of the rotary lifting motor 401, the ceiling can vibrate while being lifted, which helps to remove snow more effectively, while avoiding damage to the ceiling structure and increasing the service life of the ceiling structure.

[0029] In addition, it should be noted that the rotary lifting motor 401 is composed of a motor body, a transmission system, a control system and other components, among which the motor body is the core of the rotary lifting motor and provides power, and the transmission system converts the rotational motion of the motor into linear motion, which is usually achieved through mechanical devices such as a lead screw, a gear set or a belt drive; lead screw drive is the most common lifting transmission method, in which the motor rotates through the spiral lead screw and the nut moves along the axial direction of the lead screw to achieve linear motion; the control system is responsible for the start, stop, direction and speed control of the motor. The structure and principle of the above-mentioned rotary lifting motor 401 are all existing technologies and will not be elaborated here.

[0030] The working principle of the rotary lifting mechanism 4 is as follows: when the trigger mechanism 5 reaches the trigger point and the circuit is connected, the rotary lifting motor 401 starts, thereby driving the rotary rod 402 to rotate and lift, so that under the action of the two disc ratchet wheels 4031, the connecting block 405 can achieve regular vibration during the rising process, thereby driving one end of the rail transit elevated station roof 11 to lift and vibrate, thereby achieving the treatment of accumulated snow.

[0031] In one embodiment, for the above-mentioned trigger mechanism 5, the trigger mechanism 5 includes two groups of support plates 501 relatively arranged at the top end of the connecting block 405, and the two groups of support plates 501 are connected by a spring 502, a contact switch 503 is arranged at the top end of the support plate 501 located at the bottom, and a push rod 504 is arranged at the bottom end of the support plate 501 located at the top; the support plate 501 located at the bottom is fixedly connected to the connecting block 405, and the support plate 501 located at the top is fixedly connected to the connecting column 6; a reset contact 1101 is arranged at the bottom end of the ceiling 11 of the rail transit elevated station near one end of the fixed support column 3; a reset rod 701 cooperating with the reset contact 1101 is arranged on the outer side of the fixed cylinder 7 located at the top end of the fixed support column 3, so that the snow on the ceiling can be automatically removed, and it can also be automatically reset after completing the snow removal task, preparing for the next automatic removal of snow, saving the time and cost of manual reset.

[0032] In addition, it should be noted that the contact switch 503 is an electrical switch, which includes at least one pair of normally open (NO) and normally closed (NC) contacts. When there is no external force, the normally open contact is in an open state, while the normally closed contact is in a closed state. When an external force acts on the contact switch, the contact state changes: the normally closed contact is open, and the normally open contact is closed. When the weight of the snow on the ceiling increases, the push rod 504 will apply pressure to the contact switch 503. This pressure causes the normally closed contact to open and the normally open contact to close, thereby connecting the circuit, starting the motor of the rotating lifting mechanism 4, and starting the snow removal process.

[0033] The reset contact 1101 is an electrical switch, usually including at least one pair of normally open (NO) and normally closed (NC) contacts. When there is no external force, the normally open contact is in an open state, and the normally closed contact is in a closed state. When an external force acts on the reset contact, the contact state changes: the normally closed contact is disconnected, and the normally open contact is closed, thereby connecting the circuit, reversely starting the motor of the rotating lifting mechanism 4, and starting the reset process.

[0034] The working principle of the trigger mechanism 5, the reset contact 1101 and the reset rod 701 is as follows: when snow accumulates on the top of the rail transit elevated station roof 11 and one end of itself moves downward, the distance between the support plates 501 will be shortened and the spring 502 will be deformed. At the same time, the push rod 504 releases the contact switch 503, so that the circuit is connected, thereby starting the rotary lifting mechanism 4 to process the accumulated snow. When the rail transit elevated station roof 11 is lifted to a certain extent, the reset rod 701 contacts the reset contact 1101, triggering the reset circuit to reverse the rotary lifting mechanism 4, thereby enabling the rail transit elevated station roof 11 to not vibrate during the reset process.

[0035] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0036] In actual application, when snow falls, snow will accumulate on the top of the elevated rail transit station roof 11, which will increase the weight of the elevated rail transit station roof 11, and then one end of the elevated rail transit station roof 11 will move downward, and then the trigger mechanism 5 will reach the trigger point, and the circuit will be connected, so that the rotating lifting mechanism 4 (the working principle of the rotating lifting mechanism 4 is as described above) pushes one end of the elevated rail transit station roof 11 to lift and generate regular vibrations to help remove snow. When the elevated rail transit station roof 11 reaches the preset maximum inclination angle, the other end of the elevated rail transit station roof 11 triggers the reset circuit through the reset contact 1101 and the reset rod 701 (the working principles of the trigger mechanism 5, the reset contact 1101 and the reset rod 701 are as described above) to reverse the rotating lifting mechanism 4, so that the entire snow removal device is reset, and the roof will not vibrate during the reset process.

[0037] In summary, with the help of the above-mentioned technical scheme of the utility model, the utility model can automatically identify whether the snow accumulation on the ceiling has reached a critical weight, and can increase the inclination angle of the ceiling by starting the rotating lifting mechanism 4. At the same time, vibration is generated during the lifting process to achieve the snow removal effect without manual intervention, thereby improving the snow removal efficiency and response speed, greatly improving the safety of the station, and being able to cope with continuous and high-intensity snowfall; by setting up the rotating lifting mechanism 4, the ceiling can be vibrated while being lifted under the drive of the rotating lifting motor 401, helping to remove the snow more effectively, while avoiding damage to the ceiling structure and increasing the service life of the ceiling structure; by setting up the trigger mechanism 5 and the reset contact 1101, the snow on the ceiling can be automatically removed, and it can also automatically reset after completing the snow removal task, preparing for the next automatic removal of snow, saving the time and cost of manual reset.
