Description

Technical Field

[0001] This utility model relates to the field of waste detection technology, and in particular to a device for detecting the overflow state of waste containers. Background Technology

[0002] With the accelerating pace of urbanization, the amount of urban household waste generated continues to increase, making the operational efficiency of waste collection and transportation an increasingly important concern. Fixed waste collection stations, as crucial nodes in urban waste collection, undertake the functions of centralized storage and transfer of household waste. Currently, these stations generally use standardized, large, detachable waste containers, which are loaded, unloaded, and transferred regularly by specialized collection vehicles. In recent years, with the widespread application of new-generation information technologies such as the Internet of Things and big data in municipal management, urban sanitation systems are developing towards refined management. Against this backdrop, real-time monitoring and data analysis of waste container status helps optimize collection route planning, improve operational efficiency, and enhance public health services. In particular, developing suitable status monitoring technologies for mobile and detachable waste containers has become a direction for technological development in the industry.

[0003] Chinese patent document 202011241743.X discloses a trash can with overflow detection, including a body, an inner liner disposed within the body, and a rain cover disposed above the opening of the inner liner. A weighing device is provided at the bottom of the body, and the inner liner is supported on the weighing device. At least one distance sensor is disposed on the rain cover facing the inner liner. A column is provided along the height direction on one side of the body, and a sliding groove is provided in the column. The rain cover is slidably disposed in the sliding groove by a sliding rod. A compaction block is also provided on the side of the rain cover facing the inner liner. The device also includes a driving component for driving the sliding rod to move up and down.

[0004] However, the above-mentioned solutions have at least the following technical problems during implementation: sensors at single fixed points are inaccurate and prone to false alarms and missed alarms. Therefore, there is an urgent need to propose a waste container overflow detection device. Summary of the Invention

[0005] In view of the above technical problems, this disclosure provides a garbage container overflow detection device, which solves the technical problems of inaccurate detection and false alarms and missed alarms caused by single fixed-point sensors in the prior art.

[0006] According to one aspect of this disclosure, a garbage container overflow detection device is provided, applied to a detachable garbage container in a fixed garbage station; the detection device includes a distance detection component installed above the detachable garbage container for monitoring the height of garbage inside the detachable garbage container; the distance detection component is signal-connected to a control unit for issuing control commands when the garbage is overflowing; the distance detection component is mounted on a drive mechanism, which is signal-connected to the control unit for driving the distance detection component to rotate, thereby scanning the internal area of ​​the detachable garbage container; In some embodiments of this disclosure, the drive mechanism includes a rotating assembly mounted on a detachable waste container via a bracket. The rotating assembly includes a motor, a shaft mounted on the power output shaft of the motor, and a distance detection assembly mounted on the shaft to adjust the rotation direction of the distance detection assembly.

[0007] In some embodiments of this disclosure, the rotating shaft is mounted with a hinge structure to adjust the longitudinal angle of the distance detection component.

[0008] In some embodiments of this disclosure, the drive mechanism further includes a lifting section comprising a plurality of hydraulic telescopic cylinders mounted on a bracket surrounding the rotating shaft, for lifting the rotating shaft and distance detection assembly out of the removable waste container when it is overflowing.

[0009] In some embodiments of this disclosure, the distance detection component is an ultrasonic sensor or a laser rangefinder.

[0010] In some embodiments of this disclosure, the control unit is also signal-connected to an audible and visual alarm for issuing an audible and visual alarm signal when the garbage is overflowing.

[0011] In some embodiments of this disclosure, a housing for accommodating a detachable waste container is also included, the housing having a waste disposal opening on its side.

[0012] The beneficial effects of this utility model are as follows: By driving the sensor to rotate via a motor, the entire cross-section of the waste container can be scanned, effectively overcoming the problems of premature false alarms or delayed alarms caused by uneven waste stacking in traditional single-point sensors, resulting in more scientific and accurate judgment results.

[0013] The hinged structure allows the sensor to adjust its longitudinal angle, preventing the distance detection component from hitting the trash can lid during lifting, protecting the equipment, extending its service life, and improving the reliability of the distance measurement data.

[0014] The control unit is linked to an audible and visual alarm, which can immediately emit audible and visual signals when the garbage overflows, actively notifying management personnel or sanitation workers. This changes the previous passive mode that relied on manual patrols, enabling on-demand scheduling of garbage collection and improving response speed and work efficiency.

[0015] The entire detection and alarm process requires no manual intervention, reducing the labor costs of managing and maintaining the waste station.

[0016] To resolve conflicts during garbage collection, traditional fixed sensors require manual removal before garbage trucks arrive, otherwise they are easily damaged by collisions. This device's hydraulic lifting unit automatically raises the entire detection assembly from the container, creating space for collection operations.

[0017] Automatic lifting avoids human error or mechanical collisions that may occur during each cleaning operation, protecting delicate instruments and extending the service life of the entire system.

[0018] The design employs multiple hydraulic telescopic cylinders arranged around the rotating shaft, providing a smooth and balanced lifting force, ensuring that the sensor does not shake or jam during lifting and lowering, and operates stably.

[0019] Ultrasonic or laser sensors are inherently more resistant to environmental conditions. Furthermore, the entire mechanism is mounted on top of the container via a support frame, avoiding direct contact with waste and reducing the risk of corrosion and pollution. This makes it suitable for long-term stable operation in complex environments such as waste stations.

[0020] With accurate and timely overflow information, managers can plan collection routes and shifts more rationally, achieving refined scheduling of waste collection and transportation, thereby improving the overall sanitation management level and service image of the area.

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example 1

[0023] This example discloses a device for detecting overflow status of waste containers. See [link to documentation]. Figures 1 to 2 A detachable garbage container 1 is applied to a fixed garbage station; the detection device includes a distance detection component 2 installed above the detachable garbage container 1 for monitoring the height of garbage inside the detachable garbage container; the distance detection component 2 is signal-connected to the control unit for control commands when the garbage overflows; the distance detection component 2 is mounted on a drive mechanism, which is signal-connected to the control unit for driving the distance detection component 2 to rotate in order to scan the internal area of ​​the detachable garbage container. The drive mechanism includes a rotating assembly mounted on the detachable waste container 1 via a bracket 3. The rotating assembly includes a motor 4, a rotating shaft 5 mounted on the power output shaft of the motor 4, and a distance detection assembly 2 mounted on the rotating shaft 5 to adjust the rotation direction of the distance detection assembly 2.

[0024] The distance detection component 2 is mounted on the pivot 5 via the hinge structure 6 to adjust the longitudinal angle of the distance detection component 2.

[0025] The drive mechanism also includes a lifting unit, which includes multiple hydraulic telescopic cylinders 7. The hydraulic telescopic cylinders 7 are mounted on the bracket 3 and surround the rotating shaft 5, and are used to lift the rotating shaft 5 and the distance detection component 2 out of the detachable waste container 1 when it is overflowing.

[0026] The distance detection component 2 is an ultrasonic sensor or a laser rangefinder.

[0027] The control unit is also connected to an audible and visual alarm to issue an audible and visual alarm signal when the garbage is overflowing.

[0028] It also includes a housing 8 for accommodating the detachable waste container 1, with a waste disposal port 9 provided on the side of the housing 8.

[0029] During operation, upon startup, the control unit issues a command, and the drive mechanism begins to work. Motor 4 drives the rotating shaft 5 to rotate, causing the distance detection component 2 mounted on the shaft to scan the interior of the detachable waste container 1 below. During rotation, the distance detection component 2 continuously emits detection signals towards the bottom of the waste container, thereby monitoring the height of the waste surface in real time. The rotation of the shaft 5 allows the sensor to scan the entire cross-section of the container, avoiding misjudgments caused by uneven waste accumulation. The control unit receives and processes the data from the distance detection component 2. When the detected waste height continuously reaches or exceeds the preset overflow threshold, the control unit determines that the container is full. An audible and visual alarm is activated to alert management personnel or cleaning staff. Simultaneously, the control unit issues a command to the lifting unit. Multiple hydraulic telescopic cylinders 7 surrounding the shaft operate synchronously, lifting the entire shaft 5 and the distance detection component 2 from the full waste container, creating a safe and unobstructed space for subsequent disassembly and removal operations. The hinge structure 6 at the end of the rotating shaft 5 allows for adjustment of the longitudinal angle of the distance detection component 2, preventing collision with the trash can lid during lifting. After the trash is emptied and the container is reset, the hydraulic telescopic cylinder 7 can be controlled to descend, allowing the distance detection component 2 to return to its working position and begin a new monitoring cycle.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this application and their equivalents, this utility model also intends to include these modifications and variations.
