Description

Technical Field

[0001] This invention belongs to the field of municipal sanitation machinery technology, specifically relating to an intelligent snow collection and compression vehicle and a snow collection and compression method. Background Technology

[0002] Winter snowfall causes significant inconvenience to urban traffic and residents' travel. Traditional snow removal methods mainly rely on manual shoveling and spreading de-icing agents, which are inefficient, labor-intensive, and have negative environmental impacts. Currently, snow removal equipment includes snowplows or snow blowers, but these devices have relatively limited functionality, typically only able to dump snow on the roadside and failing to effectively collect and transport it. The current method for clearing roadside snow involves manually collecting the snow and then manually transporting the accumulated snow into transport vehicles, which also obstructs traffic. Furthermore, loose, accumulated snow is bulky, resulting in low transportation efficiency and occupying significant storage space in transport vehicles, leading to high snow transport costs.

[0003] Therefore, this application proposes an intelligent snow collection and compression vehicle and a snow collection and compression method to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems of existing snow removal equipment having relatively limited functionality, requiring manual snow transport, and the large space occupied by loose snow, thus reducing transport efficiency and increasing transportation costs.

The four wheels are respectively mounted on the base plate via the double wishbone, with two wheels located at the front end of the base plate and the other two wheels located at the rear end of the base plate. Each wheel is connected to a corresponding brake for braking.

[0009] Furthermore, the snow collection mechanism includes a snow shovel, a snow collection belt, a snow collection baffle, a snow collection guide plate, and a power input shaft. Snow collection baffles are installed on both sides of the snow collection belt to constrain the movement path of the snow. The snow shovel is arranged at the bottom front end of the snow collection baffle and connected to it. The snow collection belt is located above and behind the snow shovel to receive and transport the snow fed in by the snow shovel upwards. The snow collection guide plate is arranged at the output end of the snow collection belt to guide the snow into the compression mechanism. The snow collection guide plate is installed on the snow collection baffle. The power input shaft is rotatably installed on the snow collection baffle.

[0010] Furthermore, the snow collection belt is a scraper conveyor belt, and the snow collection diversion plate is an arc-shaped plate structure.

[0011] Furthermore, the compression mechanism includes a compression box body, a compression push plate, a lifting arm, a compression push rod, a discharge push rod, and a discharge door. The compression box body is mounted on a base plate. One end of the lifting arm is hinged to the compression box body, and the other end of the lifting arm is hinged to the compression push plate via a connecting rod. The compression push plate is slidably arranged inside the compression box body. Two compression push rods are symmetrically connected between the lifting arm and the compression push plate. The cylinder of each compression push rod is hinged to the lifting arm, and the telescopic end of the compression push rod is hinged to the compression push plate. A discharge push rod is installed on the side wall of the compression box body, and the telescopic end of the discharge push rod is connected to the discharge door.

[0013] Furthermore, the intelligent control module includes an intelligent control module body, a snow accumulation monitoring sensor, an intelligent connected vision system, a pressure sensor, and a battery controller. The battery unit is connected to the intelligent control module body through the battery controller. The snow accumulation monitoring sensor and the intelligent connected vision system are respectively connected to the intelligent control module body via signal.

[0014] Option 2: A snow compression method for an intelligent snow compression vehicle, which is based on the intelligent snow compression vehicle described in Option 1, and includes the following steps:

[0015] Snow collection operation: Snow monitoring sensors monitor the snow conditions in real time and provide environmental perception through the intelligent connected vision system. The main body of the intelligent control module coordinates the vehicle to move to the snow-covered area based on the collected information. The battery controller manages the energy distribution of the battery unit to the whole vehicle. The snow collection mechanism located at the front of the vehicle starts to work. The snow collection shovel collects the snow on the road and transports it upward through the snow collection belt. The snow is then guided into the compression box of the compression mechanism through the snow collection diversion plate.

[0016] Compression operation: After the snow enters the main body of the compression chamber of the compression mechanism, the compression pusher drives the compression push plate to compress the snow in the main body of the compression chamber. The degree of snow compaction is determined by the compression force data transmitted by the pressure sensor.

[0017] Unloading operation: After the compression operation is completed, the unloading push rod extends and opens the unloading door on the side wall of the compression box. The unloading motor is turned on and drives the gear to rotate. Under the condition of gear and rack meshing, the unloading push plate is pushed out.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0032] The connections mentioned in this invention are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0033] Example 1, combined with Figures 1-8 This embodiment describes an intelligent snow collection and compression vehicle, which includes a chassis mechanism 1, a snow collection mechanism 2, a compression mechanism 3, and an intelligent control module 4. The snow collection mechanism 2, the compression mechanism 3, and the intelligent control module 4 are integrated on the chassis mechanism 1. The snow collection mechanism 2 is located at the front of the chassis mechanism 1, and the compression mechanism 3 is located at the output end of the snow collection mechanism 2. The intelligent control module 4 is connected to the chassis mechanism 1, the snow collection mechanism 2, and the compression mechanism 3 respectively.

[0034] A battery unit 5 is installed on the chassis mechanism 1. The battery unit 5 uses a hydrogen fuel cell. The battery unit 5 is connected to the battery controller 45 of the intelligent control module 4. The battery controller 45 is a hydrogen energy battery controller, model Haiyi New Energy HYV. The power distribution is managed and energy consumption is optimized through the battery controller 45. The main body 41 of the intelligent control module is a box-type structure, model SIEMENS SIMATIC S7-1500 Advanced Controller. The main body 41 of the intelligent control module is connected to the battery unit 5 through the battery controller 45. It has a central processing unit and a wireless communication module inside. The snow accumulation detection sensor 42 is model SICK-DT50-P1124. Multiple snow accumulation detection sensors 42 are distributed at the front of the vehicle. The snow accumulation detection sensor 42 detects snow depth and density. The intelligent connected vision system 43 is model FLIR A70 intelligent vision system. The intelligent connected vision system 43 identifies road obstacles and snow conditions. The pressure sensor 44 is model CZL6W-90T. The pressure sensor 44 is embedded in the compression push plate 32 and feeds back the pressure value to the main body 41 of the intelligent control module.

[0035] As attached Figure 2As shown, the chassis mechanism 1's base plate 11 is made of high-strength aluminum alloy, bearing the weight of the entire vehicle. The steering system 12 controls the steering of the wheels 16 via a servo motor, ensuring agile driving. Double wishbone suspensions 13 connect the wheels 16 to the base plate 11, buffering road impacts. The drive motor 14 is a hub motor, integrated inside the wheels 16. All four wheels 16 are mounted on the base plate 11. The brake 15 uses an electro-disc brake, providing emergency braking functionality and enhancing safety. The wheels 16 are anti-skid tires with deep treads to enhance grip and adapt to icy and snowy road conditions.

[0036] As attached Figure 3 As shown, the snow collection mechanism 2 is mainly used for collecting and transporting snow. The snow collection shovel 21 of the snow collection mechanism 2 is made of steel plate. The snow collection shovel 21 is arranged at the front bottom of the snow collection baffle 23 and connected to the snow collection baffle 23. The angle of the snow collection shovel 21 can be adjusted appropriately. The snow collection belt 22 is a cold-resistant PVC scraper conveyor belt, driven by the power input shaft 25, which transports the snow from the snow collection shovel 21 to the compression box body 31 of the compression mechanism 3. The snow collection baffle 23 is fixed on both sides of the snow collection shovel 21 and the snow collection belt 22 to prevent snow from overflowing. The snow collection guide plate 24 is an adjustable guide plate with an arc-shaped plate structure to optimize the snow flow path and improve collection efficiency. The power input shaft 25 and the rotating shaft installed between the snow collection baffle 23 form the transmission device of the snow collection belt 22. The power input shaft 25 is connected to the motor to realize the transmission of power.

[0037] As attached Figure 4 and Figure 5 As shown, the compression mechanism 3 is mainly used for compressing and storing snow. The compression box body 31 of the compression mechanism 3 is a rectangular box with a smooth interior to reduce resistance. The compression push plate 32 is located inside the box. The compression push plate 32 moves linearly under the action of the compression push rod 34, the lifting arm 33, and the connecting rod 40, thereby compressing the snow inside the compression box body 31. One end of the lifting arm 33 is hinged to the compression box body 31, and the other end of the lifting arm 33 is hinged to the compression push plate 32 through the connecting rod 40. The up and down movement of the compression push plate 32 is controlled by the extension and retraction of the compression push rod 34. During the compression process, the pressure sensor 44 monitors the pressure inside the box in real time to ensure uniform compression.

[0038] The side wall of the compression chamber body 31 has a discharge port, and a discharge door 36 is installed at the discharge port. The discharge door 36 is connected to the telescopic end of the discharge push rod 35. The cylinder end of the discharge push rod 35 is installed on the side wall of the compression chamber body 31. When the discharge push rod 35 retracts, the discharge door 36 blocks the discharge port. When the discharge push rod 35 extends, the discharge door 36 is opened to discharge the material. The compression chamber body 31 has a sliding discharge push plate 37. A discharge motor 38 is installed on the back of the discharge push plate 37. The actuator end of the discharge motor 38 is connected to a gear 39. The gear 39 meshes with a rack 30 installed on the inner side wall of the compression chamber body 31. When the discharge motor 38 is turned on and drives the gear 39 to rotate, it controls the discharge push plate 37 to push out the compressed snow blocks to complete the discharge.

[0039] As attached Figure 7 and Figure 8 As shown, when the vehicle travels to the snow-covered area, the snow monitoring sensor 42 of the intelligent control module 4 detects the snow condition and automatically adjusts the parameters of the snow collection mechanism 2. The snow shovel 21 cuts into the snow layer, and the snow is guided by the snow shovel 21 to the snow collection belt 22 and transported to the compression box body 31 through the snow collection diversion plate 24. During the operation, the surrounding environment is monitored in real time by the intelligent network vision system 43 to avoid collisions.

[0040] After the snow enters the main body 31 of the compression chamber, the compression push rod 34 drives the compression push plate 32 to compress the snow. The pressure sensor 44 adjusts the pressure value to the preset range in real time. After compression, the unloading push rod 35 opens the unloading door 36. The unloading motor 38, through the cooperation of the gear 39 and the rack 30, drives the unloading push plate 37 to push out of the main body 31 of the compression chamber, pushing out the compressed snow blocks inside the main body 31. After unloading is completed, the unloading motor 38 rotates in the opposite direction to retract the unloading push plate 37, and the unloading push rod 35 retracts to close the unloading door 36, completing one snow compression and unloading operation.

[0041] Example 2, combined with Figures 1-8 This embodiment describes a snow compression method for an intelligent snow compression vehicle, comprising the following steps:

[0042] Snow collection operation: Snow monitoring sensor 42 monitors the snow conditions in real time and provides environmental perception through intelligent connected vision system 43. The intelligent control module 41 coordinates the vehicle to move to the snow-covered area by collecting the information. The battery controller 45 manages the energy distribution of the battery unit 5 to the whole vehicle. The snow collection mechanism 2 located at the front of the vehicle starts to work. The snow collection shovel 21 collects the snow on the road and transports it upward through the snow collection belt 22. The snow is then guided into the compression box 31 of the compression mechanism 3 through the snow collection guide plate 24.

[0043] Compression operation: After the snow enters the compression box body 31 of the compression mechanism 3, the compression pusher 34 drives the compression pusher plate 32 to compress the snow in the compression box body 31. The degree of snow compaction is determined by the compression force data transmitted by the pressure sensor 44.

[0044] Unloading operation: After the compression operation is completed, the unloading push rod 35 extends and opens the unloading door 36 on the side wall of the compression box body 31. The unloading motor 38 is turned on and drives the gear 39 to rotate. Under the condition that the gear 39 meshes with the rack 30, the unloading push plate 37 is pushed out. During the process of pushing out the unloading push plate 37, the compressed snow blocks are pushed out through the side wall opening of the compression box body 31, thus completing the unloading of the snow blocks.

[0045] This embodiment is merely an exemplary illustration of the present invention and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of the present invention, they are all within the scope of protection of the present invention.
