Description

Technical Field

[0001] This utility model relates to the field of weighbridge measurement and early warning technology, and in particular to a weighbridge measurement and early warning protection device for garbage transfer vehicles and a garbage transfer station. Background Technology

[0002] Currently, garbage transfer stations primarily use weighbridge systems for static weighing of garbage trucks. This static system relies on indicator lights before and after the scale, along with a barrier gate to guide and restrain vehicles as they pass through the weighbridge, normally preventing data errors. However, in actual operation, driver violations during weighing can easily lead to data errors and safety accidents. For example, during frequent vehicle traffic, if a vehicle leaves the weighbridge before being weighed and a following vehicle enters immediately, rear-end collisions or congestion are highly likely, affecting not only the accuracy and efficiency of the weighing data but also posing significant safety hazards. Furthermore, when garbage trucks enter the transfer station for weighing, inadequate sealing or overloading often results in the spillage of leachate and the emission of foul odors, causing serious pollution to the weighbridge area and surrounding environment.

[0003] Currently, the management of vehicle entry and exit order mainly relies on the drivers' self-discipline or the manual command of on-site dispatchers. This results in low automation, low management efficiency, and an inability to achieve effective hard constraints. Regarding the odor problem in the weighbridge area, manual spraying of deodorizing agents or timed spraying is often used, which suffers from problems such as delayed response, incomplete coverage, and significant waste of agents.

[0004] Therefore, those skilled in the art urgently need a comprehensive early warning and protection device that can automatically and intelligently solve the problems of environmental pollution and operational safety in weighbridge areas. Utility Model Content

[0044] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] refer to Figures 1 to 5 As shown in the figure, the present invention proposes a weighbridge metering early warning and protection device for a garbage transfer vehicle, comprising: a weighbridge; a front trigger sensing module and a rear trigger sensing module symmetrically arranged at the front and rear ends of the weighbridge; at least one height-adjustable arched support 11 arranged at one end of the weighbridge body and spanning across the vehicle's direction of travel, the arched support 11 being equipped with an odor detection probe 12 and a spray probe 13, the spray probe 13 extending to an external liquid storage container via a flexible pressure pipeline; and a controller, which is respectively connected to the weighbridge, the front trigger sensing module, the rear trigger sensing module, the odor detection probe 12, and the spray probe 13.

[0046] This embodiment, through the collaboration of the pre- and post-weighing triggering modules and the controller, constructs an early warning triggering zone within the weighbridge's measurement range. This accurately monitors the weighbridge's occupancy status, effectively resolving collisions and congestion issues that may result from disorderly vehicle entry and exit, ensuring the safety and efficiency of the measurement operation. Simultaneously, the collaboration between the odor detection probe 12 and the spray probe 13 with the controller enables precise deodorization of garbage trucks, significantly suppressing odor diffusion, improving the weighbridge station environment, and reducing the waste of deodorizing agents.

[0047] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0048] First, refer to Figure 1 As shown, the weighbridge includes a weighbridge body and a barrier gate mechanism. The barrier gate mechanism is located at the rear of the weighbridge body, and both the weighbridge body and the barrier gate mechanism are connected to a controller. The weighbridge body is used to weigh garbage trucks and send the weighing data to the controller. The barrier gate mechanism is used to lower the barrier gate when a garbage truck enters the weighing area of ​​the weighbridge body based on an interception command sent by the controller, and to raise the barrier gate after the controller receives the weighing data from the weighbridge body and sends a release command, thus allowing the weighed garbage truck to pass.

[0049] Next, refer to Figure 1 As shown, the front-of-scale trigger sensing module includes a first weighing indicator light 61, a first column, and a first through-beam photoelectric sensor 31 mounted on the first column. The first through-beam photoelectric sensor 31 is used to acquire the rising edge signal triggered by a vehicle entering the scale. The rear-of-scale trigger sensing module includes a second weighing indicator light 62, a second column, and a second through-beam photoelectric sensor 32 mounted on the second column. The second through-beam photoelectric sensor 32 is used to acquire the falling edge signal triggered by a vehicle exiting the scale. Both the first weighing indicator light 61 and the second weighing indicator light 62 have a red light state (prohibiting passage) and a green light state (allowing passage).

[0050] Furthermore, both the first and second uprights are configured as liftable uprights, each comprising a base, a sliding component, and a drive assembly. One end of the base is fixed to the ground, while the other end has a sliding cavity. The sliding component is movably fitted into the sliding cavity and can move axially within the cavity under the drive assembly. The drive assembly may include a servo motor and a servo driver. The servo driver is connected to both the controller and the servo motor. Upon receiving a lifting command from the controller, the servo driver generates a motor drive signal and sends it to the servo motor. The rotating end of the servo motor is connected to the sliding component. Upon receiving the motor drive signal from the servo driver, the rotating end of the servo motor operates, driving the sliding component to move axially within the sliding cavity, thereby raising or lowering the liftable upright. With both the first and second uprights configured as liftable uprights, the height of the photoelectric sensor's beam angle can be adjusted according to the height of the garbage truck to obtain the optimal beam warning area. This avoids signal loss when vehicles of different heights pass by because the beam angle signal is fixed at a certain height. Furthermore, when not in use, it can be lowered to its lowest height to protect the through-beam photoelectric sensor on the column.

[0051] Furthermore, the area between the first through-beam photoelectric sensor 31 and the second through-beam photoelectric sensor 32 is configured as a warning trigger area, and the distance between the first through-beam photoelectric sensor 31 and the second through-beam photoelectric sensor 32 is greater than the length of the garbage truck.

[0052] For further explanation, please refer to [reference needed]. Figures 3 to 5 As shown, when the first weighing indicator 61 is red, if the garbage truck crosses the beam area of ​​the first through-beam photoelectric sensor 31, the garbage truck will be weighed prematurely. At this time, the first through-beam photoelectric sensor 31 triggers an alarm signal that closes relay KA1 and opens relay KA2. When the garbage truck enters the warning trigger area for weighing, the first weighing indicator 61 and the second weighing indicator 62 switch from green to red, and the barrier gate is in an intercepting state. If the garbage truck crosses the beam area of ​​the first through-beam photoelectric sensor 31, the garbage truck is not fully weighed, and the first through-beam photoelectric sensor 31 triggers an alarm signal that closes relay KA1 and opens relay KA2. If the garbage truck crosses the beam area of ​​the second through-beam photoelectric sensor 32, the garbage truck will be dismounted prematurely, and the second through-beam photoelectric sensor 32 triggers an alarm signal that opens relay KA1 and closes relay KA2.

[0053] Secondly, when the number of arched supports 11 is configured as one, the arched support 11 is set at the front end of the weighbridge and spans across the vehicle's direction of travel. When the number of arched supports 11 is configured as two, the arched supports 11 are set at the front and rear ends of the weighbridge and span across the vehicle's direction of travel.

[0054] Further, refer to Figure 2 As shown, the arched bracket 11 is equipped with an odor detection probe 12 and a spray probe 13. The spray probe 13 extends to an external liquid storage container through a flexible pressure pipeline. A lifting adjustment device 20 is provided at the bottom of the column section of the arched bracket 11. The lifting adjustment device 20 can adjust the height of the arched bracket 11 according to the vehicle height.

[0055] For further explanation, please refer to [reference needed]. Figures 3 to 5 As shown, when the first weighing indicator 61 is green and the garbage truck enters the beam area of ​​the first through-beam photoelectric sensor 31, the first through-beam photoelectric sensor 31 triggers a rising edge signal and sends it to the odor detection probe 12. The odor detection probe 12 starts and performs odor detection. After receiving the odor concentration exceeding the standard signal from the odor detection probe 12, the controller sends a deodorizing spray command to the spray probe 13, so that the deodorizing agent in the external storage container is sprayed into the designated space through the flexible pressure pipeline via the spray probe 13. When the second weighing indicator 62 is green and the garbage truck enters the beam area of ​​the second through-beam photoelectric sensor 32, the second through-beam photoelectric sensor 32 triggers a falling edge signal and sends it to the controller. After receiving the falling edge signal, the controller sends a stop spray command to the odor detection probe 12 and the spray probe 13.

[0056] Then, the weighbridge metering early warning and protection device also includes a video acquisition unit 40 connected to the controller. The lens of the video acquisition unit 40 is pointed in the direction of the weighbridge to scan the surface of the weighbridge and the cab of the garbage truck.

[0057] To further explain, when the first weighbridge indicator light 61 is green and the garbage truck enters the area of ​​the first through-beam photoelectric sensor 31, the first through-beam photoelectric sensor 31 triggers a rising edge signal and sends it to the video acquisition unit 40. The video acquisition unit 40 starts scanning the weighbridge direction to acquire video data of the weighbridge surface and the garbage truck's cab, and then transmits the video data to the controller. When the second weighbridge indicator light 62 is green and the garbage truck enters the area of ​​the second through-beam photoelectric sensor 32, the second through-beam photoelectric sensor 32 triggers a falling edge signal and sends it to the controller. After receiving the falling edge signal, the controller sends a stop video acquisition command to the video acquisition unit 40.

[0058] Furthermore, the weighbridge weighing early warning and protection device also includes a wireless communication transceiver for information exchange between the controller and the garbage truck and video acquisition unit 40.

[0059] Finally, the weighbridge weighing early warning and protection device also includes an audible and visual alarm 50 connected to the controller, which activates the alarm based on the alarm signal sent by the controller.

[0060] On the other hand, this embodiment also provides a waste transfer station, which includes: a waste transfer vehicle; a waste collection bin; and the aforementioned weighbridge metering early warning and protection device for the waste transfer vehicle.

[0061] In summary, this utility model embodiment provides a weighbridge weighing early warning and protection device for garbage transfer vehicles and a garbage transfer station. The device includes a weighbridge, symmetrically arranged front / rear trigger sensing modules, an adjustable arched bracket 11 with an odor detection probe 12 and a spray probe 13, and a controller. The front / rear trigger sensing modules use through-beam photoelectric sensors to accurately define the early warning trigger area based on the weighbridge's measurement range, coordinating with the barrier gate and indicator lights to regulate the vehicle weighing process and effectively prevent collisions and congestion. Simultaneously, the odor detection probe 12 triggers automatic spray deodorization of the garbage transfer vehicle, suppressing odor diffusion and conserving chemicals. Furthermore, the device can integrate video monitoring, wireless communication, and audible and visual alarm functions, achieving comprehensive intelligent management of the weighbridge area and significantly improving the operational safety and environmental hygiene of the garbage transfer station.
