Description

Technical Field

[0001] This invention belongs to the technical field of waste disposal and relates to an underground waste station with automatic waste compression function. Background Technology

[0002] The sanitation department's charging standards for garbage collection in residential areas vary depending on the region, the amount of garbage, and the type of garbage. Generally, the charging standard for the collection of household waste, construction waste, and other types of garbage is per cubic meter. Some areas may adopt a per-bin charging method. For cost-effectiveness considerations, some garbage compression bins or devices have emerged.

[0003] Currently, most residential areas have ground-level garbage collection points. These are simple sheet metal boxes with built-in garbage bins and no compression function. Then, all the garbage bins from nearby collection points that are full are sent to a compression point for compression before being processed by garbage trucks. Alternatively, the uncompressed garbage bins from the original collection points are left to be processed by garbage trucks. This method is time-consuming, labor-intensive, and uneconomical. Moreover, the garbage is located on the ground, which easily breeds flies and insects and produces odors.

[0004] Some residential communities are equipped with garbage compression bins. The method of use is to place the garbage bin in the appropriate area directly under the compression plate, press the button or handwheel to operate the compression plate to compress downwards, and after resetting, the compression plate rises back to the starting position. Then, garbage is added into the bin and the compression action is repeated. In some places, people even stand on top of the garbage bin and step on it to compress it, which is extremely unsafe. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose an underground garbage station with automatic garbage compression function and its usage method.

[0006] To achieve the aforementioned technical objective, the technical solution adopted by the present invention is as follows:

[0007] An underground waste station with automatic waste compression function includes a horizontally arranged upper platform and a lower platform. The lower platform is located in a waste station pit below the ground surface, while the upper platform is located on the ground. The upper platform has multiple feeding ports, each equipped with a feeder. Multiple waste bins are positioned on the lower platform, with the feeders aligned vertically with the bins. When the feeders are opened, waste can be fed into the waste bins through the feeding ports. The station is characterized by a compression device installed at each feeding port on the lower surface of the upper platform. The compression device includes a pressure plate, upper and lower telescopic units, and a horizontal closing unit. A compression device is located in the middle of the pressure plate. The system includes a pressure plate through-hole that runs vertically through the pressure plate and is aligned vertically with the feeding port. A horizontal closing unit is installed on the pressure plate and includes a horizontally movable baffle that can open, partially close, or completely close the pressure plate through-hole. An upper and lower telescopic unit is connected between the lower platform and the pressure plate and can move the pressure plate downwards, allowing the entire pressure plate to enter the garbage bin and compress the garbage inside. The underground garbage station also includes a control unit that is signal-connected to the upper and lower telescopic unit and the horizontal closing unit, and controls their operation.

[0008] To optimize the technical solution, the specific measures taken also include:

[0009] The horizontal closing unit includes horizontal closing structures symmetrically arranged on both sides of the pressure plate through hole. One horizontal closing structure includes a first horizontal drive electric cylinder, a first push plate, a first hinge shaft, and a first arc-shaped baffle. The other horizontal closing structure includes a second horizontal drive electric cylinder, a second push plate, a second hinge shaft, and a second arc-shaped baffle. The pressure plate has a first slide rail and a second slide rail symmetrically arranged on the left and right sides of the pressure plate through hole. Both the first slide rail and the second slide rail are arc-shaped slide rails extending from the corner of the pressure plate towards the center. The first horizontal drive electric cylinder is fixedly installed on... On the upper surface of the pressure plate, a first horizontal drive electric cylinder is connected to a first push plate, which is hinged to a first hinge shaft. A first arc-shaped baffle is located on the lower surface of the pressure plate, with its positioning end hinged to the pressure plate and its movable end hinged to the lower end of the first hinge shaft. The first hinge shaft passes through a first slide rail, and its upper end is hinged to the first push plate. The first horizontal drive electric cylinder can push the first push plate, causing the first hinge shaft to slide in the first slide rail. The first hinge shaft drives the first arc-shaped baffle to rotate about its positioning end. When the first hinge shaft moves to the end of the first slide rail near the corner of the pressure plate, the first arc-shaped baffle does not block the through hole of the pressure plate. When the first hinge shaft moves to the end of the first slide rail near the middle of the pressure plate, the first arc-shaped baffle partially blocks the through hole of the pressure plate. The second horizontal drive electric cylinder is fixedly installed on the upper surface of the pressure plate and is connected to the second push plate. The second push plate is hinged to the second hinge shaft. The second arc-shaped baffle is located on the lower surface of the pressure plate. The positioning end of the second arc-shaped baffle is hinged to the pressure plate, and the movable end is connected to the lower end of the second hinge shaft. The second hinge shaft passes through the second slide rail and is hinged to the second push plate at its upper end. The second horizontal drive electric cylinder can push the second push plate, causing the second hinge shaft to slide in the second slide rail. The second hinge shaft drives the second arc-shaped baffle to rotate around the positioning end of the second arc-shaped baffle. When the second hinge shaft moves to the end of the second slide rail near the corner of the pressure plate, the second arc-shaped baffle does not block the pressure plate through hole. When the second hinge shaft moves to the end of the second slide rail near the middle of the pressure plate, the second arc-shaped baffle partially blocks the pressure plate through hole.

[0010] The upper surface of the pressure plate is equipped with positioning micro switches at both ends of the first slide and the second slide. The positioning micro switches can sense the first hinge shaft that has moved to the end of the first slide and the second hinge shaft that has moved to the end of the second slide. The positioning micro switches are connected to the corresponding first and second horizontal drive cylinders. When the positioning micro switch senses the corresponding hinge shaft, the horizontal drive cylinder on that side stops operating.

[0011] A guide ring extends upward from the edge of the through hole in the pressure plate. When the upper and lower telescopic units are in the retracted state, the upper end of the guide ring abuts against the lower surface of the upper platform, and the guide ring is aligned with the feeding port.

[0012] A sensor through hole is provided at the bottom of the guide ring. An overflow sensor is installed in the sensor through hole, with the overflow sensor facing the trash can. The overflow sensor is used to sense whether the trash can is overflowing.

[0013] The edge of the pressure plate extends upward to form a garbage-proof seal, which is used to prevent garbage from moving from the side of the pressure plate to the upper surface of the pressure plate.

[0014] At least one of the first and second arc-shaped baffles is equipped with a laser sensor. The laser sensor is used to detect the distance between itself and the opposite arc-shaped baffle. The laser sensor is signal-connected to the control unit. The control unit determines the opening and closing state of the first and second arc-shaped baffles and whether there is an obstruction between the first and second arc-shaped baffles based on the information from the laser sensor.

[0015] The telescopic unit comprises two sets of telescopic components arranged in parallel. Each set includes a telescopic motor, a scissor-type telescopic frame, and a slide rail. The telescopic motor and slide rail are fixed to the lower surface of the upper platform. Of the two connection points at the upper end of the scissor-type telescopic frame, one is the active point, which is slidably connected to the slide rail, and the other is the passive point, which is hinged to the lower surface of the upper platform. The lower connection points of the scissor-type telescopic frame are all hinged to the upper surface of the pressure plate. The motor shaft of the telescopic motor is hinged to the active point of the scissor-type telescopic frame. The motor shaft of the telescopic motor can push the active point to slide on the slide rail, thereby enabling the scissor-type telescopic frame to telescopically extend and retract.

[0016] A current detector is installed on the connection circuit between the telescopic motor and the power supply, and the current detector is connected to the control unit signal.

[0017] A method for using an underground waste station with automatic waste compression function, specifically including the following steps:

[0018] Step a: When the underground garbage station is in use, the upper and lower telescopic units are in the retracted state, the pressure plate is in the upper position, the baffle of the horizontal closed unit opens the pressure plate through hole, the user opens the feeder, and the garbage can be put into the garbage bin through the feed port.

[0019] Step b: When the overflow sensor detects that the trash can is full and the trash needs to be compressed, the laser sensor detects whether there is an obstruction between the first and second arc-shaped baffles. If the laser sensor detects an obstruction between the first and second arc-shaped baffles, the compression of the trash can stops. If the laser sensor detects no obstruction between the first and second arc-shaped baffles, the control unit controls the first horizontal drive cylinder to move the first hinge axis towards one end of the first slide near the middle of the pressure plate, thereby partially blocking the through hole of the pressure plate with the first arc-shaped baffle. The control unit then controls the second horizontal drive cylinder to move the second hinge axis towards the second slide. The guide plate moves one end near the middle of the pressure plate, causing the second arc-shaped baffle to partially block the pressure plate's through hole. The first and second arc-shaped baffles work together to completely or partially block the pressure plate's through hole. The control unit controls the telescopic motor to extend the scissor-type telescopic frame, causing the pressure plate to move down and enter the garbage bin as a whole to compress the garbage. When the scissor-type telescopic frame moves to the lower end of its stroke or the current detector detects that the telescopic motor has reached the overload threshold, the control unit controls the telescopic motor to stop operating for a few seconds to prevent the garbage from rebounding. Then, the control unit controls the telescopic motor to operate in reverse, causing the scissor-type telescopic frame to retract to the upper end of its stroke, and the pressure plate to rise and reset, completing the garbage compression process.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention integrates waste collection and compression functions into an underground pit through a buried, layered design, significantly reducing surface odor emissions and fly breeding. The feeding port is flush with the ground platform, preventing waste exposure and significantly improving the community's sanitation. Simultaneously, this invention innovatively integrates an automatic compression module below the feeding port, achieving in-situ compression of waste after disposal. Through an intelligent control unit that links the opening and closing of the baffles and the raising and lowering of the pressure plates, multiple rounds of compression operations can be completed without manual intervention, significantly increasing the capacity of a single waste bin and reducing collection frequency and transportation costs.

[0022] 2. This invention adopts a closed compression structure, which completely eliminates the dangerous behavior of manual stepping on the compression, and has high operational safety. This invention can monitor the status of the compression channel in real time through laser, and will immediately terminate the compression if foreign objects are detected; the current overload protection mechanism automatically stops the equipment to prevent mechanical damage.

[0023] 3. The compression channel of this invention is equipped with an adjustable baffle system. It fully opens during feeding to ensure smooth flow, and partially closes during compression to form a guiding structure, preventing waste from getting stuck. The three-dimensional sealing design of the pressure plate edges effectively prevents waste leakage, ensuring the cleanliness of the equipment's interior.

[0024] 4. A single station integrates multiple independent compression units, supporting parallel processing of multiple trash cans. Overflow automatically triggers the compression process, reducing manual inspection costs; the increased density of compressed trash lowers collection expenses based on volume / number of cans, achieving long-term cost reduction and efficiency improvement.

[0025] In summary, this invention integrates feeding, compression, and overflow status notification through the combination of multiple structural modules. The device is highly automated and intelligent, saving manpower, material resources, and time. It is also highly user-friendly, convenient, and reduces safety hazards. Furthermore, it avoids the problem of garbage scattering on the ground during transportation, saving considerable garbage transportation and disposal costs. Attached Figure Description

[0040] The pressure plate 4 includes a pressure plate through hole 41, a first slide rail 42, a second slide rail 43, a positioning micro switch 44, a guide ring 45, a sensor through hole 46, an overflow sensor 47, and a garbage-proof sealing plate 48. The pressure plate 4 has a pressure plate through hole 41 in the middle and an anti-garbage sealing plate 48 extending upward from the edge. The guide ring 45 extends upward from the edge of the pressure plate through hole 41, and a sensor through hole 46 is opened at the bottom of the guide ring 45. The overflow sensor 47 is fixed in the sensor through hole 46.

[0041] The horizontal closing unit 6 includes a first horizontal drive electric cylinder 61, a first push plate 62, a first hinge shaft 63, a first arc-shaped baffle 64, a second horizontal drive electric cylinder, a second push plate, a second hinge shaft, and a second arc-shaped baffle. The first horizontal drive electric cylinder 61 and the second horizontal drive electric cylinder are bolted to the upper surface of the pressure plate 4. The output end of the first horizontal drive electric cylinder 61 is hinged to the first push plate 62, and the first push plate 62 is hinged to the upper end of the first hinge shaft 63. The first hinge shaft 63 passes through the first slide rail 42, and its lower end is hinged to the movable end of the first arc-shaped baffle 64. The positioning end of the first arc-shaped baffle 64 is hinged to the lower surface of the pressure plate 4. The connection methods of the second horizontal drive electric cylinder, the second push plate, the second hinge shaft, and the second arc-shaped baffle are symmetrical and identical.

[0042] The upper and lower telescopic unit 5 includes two sets of telescopic components, which are installed in parallel on the lower surface of the upper platform 1. Each set of telescopic components includes: a telescopic motor 51 bolted to the upper platform 1; a slide rail 53 welded to the upper platform 1; the upper active point of the scissor-type telescopic frame 52 is slidably connected to the slide rail 53, and the passive point is hinged to the upper platform 1; the lower end of the scissor-type telescopic frame 52 is hinged to the upper surface of the pressure plate 4; and the motor shaft of the telescopic motor 51 is hinged to the active point of the scissor-type telescopic frame 52.

[0043] The positioning micro switch 44 is embedded on the upper surface of the pressure plate 4 and located at the ends of the first slide rail 42 and the second slide rail 43; the laser sensor is bolted to the inner surface of the first arc-shaped baffle 64; the current detector is connected in series to the power circuit of the telescopic motor 51.

[0044] The control unit is connected via cables to the overflow sensor 47, the position micro switch 44, the laser sensor, the current detector (signal input), the first horizontal drive cylinder 61, the second horizontal drive cylinder, the telescopic motor 51 (drive output), and the feeder 3.

[0045] The method of using this invention is as follows:

[0046] Initial feeding status:

[0047] The scissor-type telescopic frame 52 is in the retracted state, and the upper end of the guide ring 45 abuts against the lower surface of the upper platform 1;

[0048] The control unit drives the first horizontal drive cylinder 61 and the second horizontal drive cylinder, causing the first hinge shaft 63 to move to the corner of the first slide rail 42 and the second hinge shaft to move to the corner of the second slide rail 43. The first arc-shaped baffle 64 and the second arc-shaped baffle 64 fully open the pressure plate through hole 41. The positioning micro switch 44 triggers the "open to position" signal. The green light of the feeder 3 lights up, and the user can kick / use a sensor to open the feeder 3. The garbage enters the pressure plate through hole 41 through the feeding port and then falls into the garbage bin 21.

[0049] When overflow sensor 47 detects that trash can 21 is overflowing:

[0050] The control unit switches feeder 3 to the red light locked state, prohibiting feeding.

[0051] The laser sensor scans the channel between the first arc-shaped baffle 64 and the second arc-shaped baffle:

[0052] If there is an obstacle: keep the red light on and send an alarm SMS to the administrator via the IoT module;

[0053] Obstacle-free: Perform the compression process.

[0054] Compression execution process:

[0055] Baffle closing stage:

[0056] The control unit activates the first horizontal drive electric cylinder 61 to push the first push plate 62, causing the first hinge shaft 63 to slide along the first slide rail 42 towards the center; the first arc-shaped baffle 64 rotates around the positioning end to partially block the pressure plate through hole 41; the second horizontal drive electric cylinder is activated simultaneously, and the second arc-shaped baffle moves symmetrically; when the first hinge shaft 63 triggers the positioning micro switch 44 in the center of the first slide rail 42, the electric cylinder stops, and the double baffles form a compression channel.

[0057] Waste compression stage:

[0058] The telescopic motor 51 starts, pushing the active point of the scissor-type telescopic frame 52 to slide along the slide rail 53. The scissor-type telescopic frame 52 extends, and the pressure plate 4 moves down into the garbage bin 21 to compress the garbage. The current detector continuously monitors the current of the telescopic motor 51; if the current exceeds the threshold (overload), the control unit immediately reverses the telescopic motor 51 to retract the pressure plate 4; if the pressure plate 4 reaches the lower end of its stroke, the control unit pauses the telescopic motor 51 for a few seconds (to prevent rebound).

[0059] Reset / Unlock Phase:

[0060] The telescopic motor 51 reverses, the scissor-type telescopic frame 52 retracts, and the pressure plate 4 rises to reset; the horizontal closing unit 6 reopens the baffle; the overflow sensor 47 resets, and the feeder 3 switches back to the green light to unlock.

[0061] The embodiments described are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the embodiments described. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.

A method of using an underground waste station with automatic waste compression function, characterized in that: The application of the underground waste station as described in claim 9 specifically includes the following steps: Step a: When the underground garbage station is in use, the upper and lower telescopic units (5) are in the retracted state, the pressure plate (4) is in the upper position, the baffle of the horizontal closing unit (6) opens the pressure plate through hole (41), the user opens the feeder (3), and the garbage can be put into the garbage bin (21) through the feed port. Step b: When the overflow sensor (47) senses that the trash can (21) is full and the trash needs to be compressed, the laser sensor detects whether there is an obstruction between the first arc-shaped baffle (64) and the second arc-shaped baffle. If the laser sensor detects an obstruction between the first arc-shaped baffle (64) and the second arc-shaped baffle, the compression of the trash can (21) is stopped. If the laser sensor detects no obstruction between the first arc-shaped baffle (64) and the second arc-shaped baffle, the control unit controls the first horizontal drive cylinder (61) to drive the first hinge shaft (63) to move towards the middle of the pressure plate (4) on the first slide rail (42), so that the first arc-shaped baffle (64) partially blocks the through hole (41) of the pressure plate. The control unit controls the second horizontal drive cylinder to drive the second hinge shaft to move the second slide rail (43) axially. The first arc-shaped baffle (64) moves to the middle position of the pressure plate (4), thereby partially blocking the pressure plate through hole (41). The first arc-shaped baffle (64) and the second arc-shaped baffle cooperate to completely or partially block the pressure plate through hole (41). The control unit controls the telescopic motor (51) to operate, so that the scissor telescopic frame (52) extends, the pressure plate (4) moves down and enters the garbage bin (21) as a whole to compress the garbage. When the scissor telescopic frame (52) moves to the lower end of its stroke or the current detector detects that the telescopic motor (51) has reached the overload threshold, the control unit controls the telescopic motor (51) to stop operating for a few seconds to prevent the garbage from rebounding. Then, the control unit controls the telescopic motor (51) to operate in reverse, so that the scissor telescopic frame (52) retracts to the upper end of its stroke, the pressure plate (4) rises and resets, and the garbage compression process is completed.
