Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser ranging technology, and in particular to a laser overflow device. Background Technology
[0002] With the advancement of intelligent urban management, garbage bin overflow detection has become a key link in improving garbage collection efficiency and optimizing resource allocation. Existing technologies mostly use fixed laser rangefinders to detect the height of garbage inside the bins. These sensors are typically mounted directly on the top of the bin and can only detect in a single direction.
[0003] However, due to the randomness of garbage disposal, garbage may accumulate or protrude in certain areas inside the garbage bins, causing blind spots in laser detection, resulting in inaccurate detection results and making it easy to make false or missed judgments. Utility Model Content
[0004] The present invention aims to provide a laser overflow device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A laser overflow device includes a housing, a mounting buckle connected to the housing, a mounting groove formed in the housing, a mounting ring movably connected to the inner wall of the mounting groove, a limiting structure connected to the mounting ring for limiting the position of the mounting ring, a toothed ring connected to the mounting ring, a working groove and a driving groove formed in the housing, the driving groove communicating with the mounting groove, a rotating shaft rotatably connected to the housing, a motor connected to the inner wall of the working groove, the output end of the motor connected to the rotating shaft, a gear connected to the rotating shaft, the gear meshing with the toothed ring, an annular groove formed in the housing communicating with the mounting groove, a laser ranging sensor connected to the mounting ring, the laser ranging sensor located within the annular groove, a power source connected to the working groove, and multiple sections of electric telescopic rods connected to the housing, with pressure plates connected to the telescopic ends of the multiple sections of electric telescopic rods.
[0007] Preferably, the housing is connected to a connector, and the connector is detachably connected to a wiping sponge.
[0008] Preferably, the connector is connected to a sub-hook and loop fastener, and the wiping sponge is connected to a female hook and loop fastener, with the female hook and loop fastener and the sub-hook and loop fastener being attached together.
[0009] Preferably, the limiting structure includes a ball bearing, the mounting ring has several sets of movable grooves arranged in a circular array, the ball bearing is movably connected to the movable grooves, the housing has a limiting groove, and the ball bearing abuts against the inner wall of the limiting groove.
[0010] Preferably, the multi-section electric telescopic rod is fitted with a corrugated sleeve on its outer side, and the two ends of the corrugated sleeve are respectively connected to the housing and the pressure plate.
[0011] Preferably, the surface of the pressure plate is coated with a low surface energy coating.
[0012] Preferably, the top wall of the pressure plate is in the shape of a circular sloping platform.
[0013] Preferably, the housing is detachably connected to an inspection cover, which cooperates with the working groove.
[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:
[0015] (1) This technical solution uses a motor-driven gear meshing with a gear ring to rotate the mounting ring and laser rangefinder sensor along the ring groove, enabling omnidirectional detection of different locations inside the trash can. This effectively eliminates blind spots caused by localized accumulation and improves accuracy. Furthermore, the multi-section electric telescopic rod drives a pressure plate to compact the trash, increasing the space utilization of the trash can and reducing collection frequency. The mounting buckle facilitates fixing the device to trash cans of different sizes, and the limiting structure ensures the rotational stability of the mounting ring. The overall structure is compact and highly adaptable, optimizing the efficiency of trash overflow detection and management.
[0016] (2) By setting the connector to attach the female Velcro to the wiping sponge through the male Velcro, when the surface of the laser rangefinder sensor is contaminated with dust and stains that affect the detection accuracy, the wiping sponge can quickly clean it to ensure the detection accuracy. After the sponge has been used for a period of time, the dirty sponge can be replaced in time to maintain the cleaning effect and improve the convenience and efficiency of maintenance.
[0017] (3) By setting up ball bearings, movable grooves, and limiting grooves, the ball bearings abut against the inner wall of the limiting grooves, limiting the radial or axial displacement of the mounting ring during rotation, ensuring that it always maintains a precise rotation trajectory, thereby guaranteeing the accuracy of the laser rangefinder sensor's omnidirectional detection. Furthermore, the ball bearings convert the sliding friction between the mounting ring and the housing into rolling friction, significantly reducing friction and making the rotation of the laser rangefinder sensor driven by the motor smoother, thus reducing energy loss.
[0018] (4) By installing corrugated sleeves, the telescopic rod can be protected from corrosion by garbage, dust, and liquids, preventing the telescopic rod from being affected by foreign objects or rust, thus extending its service life. The low surface energy coating on the pressure plate reduces the adhesion between garbage and the pressure plate, making it less likely for garbage to stick to the pressure plate surface after compaction, facilitating cleaning and subsequent use. The circular sloping top wall of the pressure plate can guide garbage to slide to the surroundings using the slope, preventing garbage from accumulating on the top of the pressure plate and affecting subsequent compaction work and laser detection.
[0019] (5) By setting a detachable inspection cover, when the core components such as the motor and power supply in the working tank malfunction or need regular maintenance, the inspection cover can be opened quickly to access the internal components for inspection, replacement or cleaning, shortening maintenance time and reducing maintenance difficulty.

Detailed Implementation
[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:
[0025] like Figure 1-3The laser overflow device shown includes a housing 1, with a mounting buckle 2 connected to the side wall of the housing 1. An installation groove 15 is formed inside the housing 1, and an installation ring 14 is movably connected to the inner wall of the installation groove 15. The installation ring 14 is connected to a limiting structure, which includes ball bearings 24. Several sets of movable grooves 23 arranged in a circular array are formed on the top and bottom walls of the installation ring 14. The ball bearings 24 are movably connected to the movable grooves 23. Limiting grooves 25 are formed on the inner top and bottom walls of the installation groove 15. The limiting grooves 25 are annular, and the ball bearings 24 abut against the inner wall of the limiting grooves 25. A working groove 9 is formed on the top wall of the housing 1, and a power supply 11 is connected to the working groove 9. A maintenance cover 10 is detachably connected to the top wall of the housing 1, completely covering the working groove 9. A drive groove 16 is formed inside the housing 1, communicating with the installation groove 15. A rotating shaft 17 is rotatably connected to the housing 1, passing through a drive groove 16. A motor 12 is connected to the bottom wall of the working groove 9, and the output end of the motor 12 is connected to the rotating shaft 17. A gear 13 is connected to the rotating shaft 17, located within the drive groove 16. A gear ring 20 is connected to the inner wall of the mounting ring 14, and the gear 13 meshes with the gear ring 20. An annular groove 8 is formed on the bottom wall of the housing 1, communicating with the mounting groove 15. A laser rangefinder 7 is connected to the bottom wall of the mounting ring 14, and the laser rangefinder 7 is an infrared laser module with an accuracy of ±1mm. The laser rangefinder 7 is located within the annular groove 8. Motor 12 drives shaft 17 to rotate gear 13. Gear 13 meshes with gear ring 20 on the inner wall of mounting ring 14, causing mounting ring 14 to rotate along mounting groove 15. Simultaneously, the ball bearings 24 of the limiting structure roll within the movable groove 23 and limiting groove 25, ensuring stable rotation of mounting ring 14. Laser distance sensor 7 at the bottom of mounting ring 14 rotates with the ring, detecting the height of different positions inside the trash can through ring groove 8, and acquiring real-time data on trash accumulation. When laser distance sensor 7 passes the connector 4, its surface is wiped by wiping sponge 3.
[0026] like Figure 2-3 As shown, a connector 4 is connected to the bottom wall of the housing 1, and a sub-hook and loop fastener 21 is connected to the top wall of the connector 4. A female hook and loop fastener 22 is connected to the bottom of the wiping sponge 3, and the female hook and loop fastener 22 is attached to the sub-hook and loop fastener 21. The wiping sponge 3 cooperates with the laser rangefinder sensor 7. A multi-section electric telescopic rod 19 is connected to the center of the bottom wall of the housing 1, and a pressure plate 6 is connected to the telescopic end of the multi-section electric telescopic rod 19. A corrugated sleeve 5 is fitted on the outside of the multi-section electric telescopic rod 19, and the two ends of the corrugated sleeve 5 are connected to the bottom wall of the housing 1 and the top wall of the pressure plate 6, respectively. The top wall of the pressure plate 6 is in the shape of a circular sloping platform, and the surface of the pressure plate 6 is coated with a polytetrafluoroethylene low surface energy coating 18. When the garbage is detected to be close to the overflow threshold, the multi-section electric telescopic rod 19 extends, driving the pressure plate 6 to descend and compact the garbage. The corrugated sleeve 5 protects the telescopic rod from garbage contamination. The circular sloping platform design of the top wall of the pressure plate 6 guides the garbage to slide to the surroundings, avoiding its own accumulation, and the low surface energy coating 18 reduces garbage adhesion.
[0027] The specific implementation process is as follows:
[0028] In use, the device is fixed to the inside of the top of the trash can using the mounting buckle 2 on the side wall of the housing 1, ensuring that the laser rangefinder 7 and the pressure plate 6 are facing the space inside the can. After the device is powered on, the motor 12 drives the mounting ring 14 to rotate, and the laser rangefinder 7 performs 360° all-round height detection of the trash inside the trash can along the ring groove 8, monitoring the trash accumulation status in real time. When the laser detects that the height of the trash reaches a preset threshold, the multi-section electric telescopic rod 19 automatically extends, driving the pressure plate 6 to descend and compact the trash; after compaction, the telescopic rod retracts and resets, and the pressure plate 6 leaves the trash surface. The wiping sponge 3 can be periodically removed and cleaned or replaced using Velcro and then reattached.
