Description

Technical Field

[0001] This invention relates to the field of subway station cleaning technology, and more particularly to a snow removal device for subway stations. Background Technology

[0002] As the lifeline of modern urban transportation, the safety and efficiency of subway operations are of paramount importance. Especially during winter snowfall, subway station entrances and exits become crucial passageways for passengers. To prevent passengers from slipping, subway operators typically lay rubber anti-slip mats on steps and flat surfaces at entrances and exits. These mats effectively increase friction, ensuring passenger safety when walking through snow to enter the station. However, in actual use, especially when temperatures remain consistently low, snowfall on these mats melts rapidly and refreezes due to the combined effects of pedestrian traffic and low temperatures. This causes the snow to physically freeze onto the fibrous or textured surface of the mat, forming a hard ice shell or layer of ice particles. Traditional snow removal methods, such as shovels, snowplows, or simple brooms, are insufficient to remove the frozen ice layer from the mat due to the tight bond between the snow and ice. The remaining ice shell still reduces the anti-slip effect of the mat. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a snow removal device for subway stations.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A snow removal device for a subway station includes two corresponding car bodies. Each car body has an installation groove on its lower side. A lifting rod is hinged in the installation groove via a spring hinge. The lifting rod can generate heat. Each car body has a snow scraping device installed on its rear side. The two snow scraping devices are arranged correspondingly. Each snow scraping device includes a fixed rod with a motor mounted on it. The telescopic end of the motor is fixedly connected to an installation beam. A snow sweeping plate is provided on the lower side of the installation beam. The snow removal device is used to remove snow from the anti-slip mats laid on the ground in the subway station. During snow removal, the lifting rod extends under the anti-slip mat, and the snow sweeping plate is located above the anti-slip mat. The lifting rod lifts the anti-slip mat upward and heats it, and then the snow sweeping plate scrapes away the snow on top of the anti-slip mat.

[0005] Furthermore, an electric telescopic rod is fixedly connected to the underside of each vehicle body. The telescopic end of the electric telescopic rod is set downward and fixed to a mounting base. A scraper is fixedly connected between two mounting bases, and the scraper is set horizontally.

[0006] Furthermore, the lifting rod is tilted, and there is a cavity inside the lifting rod. A hot air inlet hose is provided on one side of the lifting rod, and the hot air inlet hose is connected to the cavity. There is an air outlet hole that passes through the lifting rod inside the cavity.

[0007] Furthermore, a clearance groove is provided on the lower side of the lever, and the scraper is located in the clearance groove.

[0008] Furthermore, the upper surface of the lifting rod is an arc-shaped surface, and a guide groove is provided on the upper surface of the lifting rod, with all air outlets located within the guide groove.

[0009] Furthermore, an electric push rod is installed on the mounting beam, with the telescopic end of the electric push rod set vertically downward and equipped with a first clamping wheel.

[0010] Furthermore, a rotatable swing rod is installed inside the mounting slot, with one end of the swing rod fixedly connected to an end post, and a second clamping wheel installed at the lower end of the end post.

[0011] Furthermore, each vehicle body is fixedly connected to a column on its upper side, and the upper ends of the two columns are jointly fixedly connected to a crossbeam. A fixing plate is installed in the middle of the crossbeam, and a detector is installed on the fixing plate. The detector can control the operation of the motor.

[0012] Advantages of this invention: This invention uses a lifting rod to lift the anti-slip mat upwards and heat it. Under the action of hot air, the frozen snow separates from the anti-slip mat. Then, a snow sweeper removes the snow on top of the anti-slip mat. When pedestrians pass by, a detector detects whether passengers or pedestrians are passing the anti-slip mat. When a passenger or pedestrian is detected, the mounting beam and snow sweeper are moved to the outside of the anti-slip mat to prevent passengers or pedestrians from tripping and eliminate the safety hazard of passengers falling.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-5 As shown, a snow removal device for a subway station in this embodiment includes two correspondingly arranged car bodies 1. The bottom of the car body 1 is equipped with a traveling wheel, and a column 61 is fixedly connected to the upper side of each car body 1. The upper ends of the two columns 61 are jointly fixedly connected to a crossbeam 6.

[0021] Each vehicle body 1 has a mounting slot 11 on its lower side. A lifting rod 3 is hinged to the mounting slot 11 via a spring hinge 12. The lifting rod 3 is angled and has a cavity 31 inside. A hot air intake hose is located on one side of the lifting rod 3, connecting to the cavity 31. An air outlet 33 penetrates the lifting rod 3 within the cavity 31, allowing hot air to be injected into the cavity 31 via the hot air intake hose, thus heating the lifting rod 3. The upper surface of the lifting rod 3 is arc-shaped, and a guide groove 32 is provided on this surface. The air outlet 33 is located within the guide groove 32. The purpose of the guide groove 32 is to ensure uniform distribution of hot air.

[0022] Each vehicle body 1 is fixedly connected to an electric telescopic rod on its lower side. The telescopic end of the electric telescopic rod is set downward and fixed to a mounting base. A scraper 2 is fixedly connected between two mounting bases, and the scraper 2 is set horizontally. The electric telescopic rod and the mounting base are at the bottom of the mounting groove 11 and are not shown because they are obscured by the mounting groove 11. The lower side of the lifting rod 3 is provided with a clearance groove 34, and the scraper 2 is located in the clearance groove 34. In this way, the scraper 2 is hidden in the clearance groove 34, which can protect it from the clearance groove 34 and save space.

[0023] Each vehicle body 1 is equipped with a snow scraper 5 on its rear side. Two snow scraper devices 5 are arranged correspondingly. Each snow scraper device 5 includes a fixed rod 51, on which a motor 52 is mounted. The telescopic end of the motor 52 is fixedly connected to a mounting beam 53. A snow sweeping plate 54 is provided on the lower side of the mounting beam 53. An electric push rod 55 is mounted on the mounting beam 53. The telescopic end of the electric push rod 55 is set vertically downward and is equipped with a first pressure wheel 56.

[0024] See Figure 6 The snow removal device disclosed in this embodiment is used to remove snow from the anti-slip mat 100 laid on the ground in the subway station. The anti-slip mat 100 is existing technology and will not be described in detail here. During snow removal, with the assistance of staff, the lifting rod 3 is inserted under the anti-slip mat 100, and the snow sweeping plate 54 is positioned above the anti-slip mat 100. The first pressing wheel 56 is pressed firmly by the electric push rod 55. The lifting rod 3 lifts the anti-slip mat 100 upward and heats it. Under the action of hot air, the frozen snow separates from the anti-slip mat 100. Then, the motor 52 drives the mounting beam 53 and the snow sweeping plate 54 to swing back and forth, thereby scraping away the snow above the anti-slip mat 100 by the snow sweeping plate 54. During this process, the anti-slip mat 100 is always pressed firmly by the first pressing wheel 56, so that the anti-slip mat 100 will not be excessively lifted by the lifting rod 3 and wrinkled during the movement of the car body 1. Meanwhile, as the vehicle body 1 moves, the electric telescopic rod pushes the scraper 2 to contact the ground, and the scraper 2 cleans the bottom surface under the anti-slip mat 100.

[0025] In a preferred embodiment of the present invention, since passengers may pass by and walk on the anti-slip mat 100 during snow removal, the present invention is designed to facilitate passenger passage as follows: First, a swing rod 41 is rotatably connected in the mounting groove 11. One end of the swing rod 41 is fixedly connected to an end post 42, and a second pressure wheel 43 is installed at the lower end of the end post 42. Simultaneously, a driver is installed in the mounting groove 11, which can drive the swing rod 41 to rotate. The driver is existing technology and will not be described in detail here. A fixing plate 62 is installed in the middle of the crossbeam 6, and a detector 63 is installed on the fixing plate 62. The detector 63 is a detection radar, which can control the motor 52 and the driver. When detector 63 detects a passenger or pedestrian crossing the anti-slip mat 100, detector 63 simultaneously controls motor 52 and driver to operate. Motor 52 drives mounting beam 53 and snowplow 54 to rotate, causing mounting beam 53 and snowplow 54 to move to the outside of anti-slip mat 100, preventing passengers or pedestrians from tripping over mounting beam 53 and snowplow 54 and eliminating the safety hazard of passengers falling. At the same time, the driver drives swing rod 41 to rotate, causing the second pressure wheel 43 to move directly above the lifting rod 3, thereby applying pressure to the lifting rod 3, causing the lifting rod 3 to change from an inclined state to a horizontal state. The lifting rod 3 is pressed tightly against the ground by the second pressure wheel 43. In this way, the lifting rod 3 under the anti-slip mat 100 will only cause the anti-slip mat 100 to bulge slightly, which can further eliminate the safety hazard of passengers falling.
