Description

Technical Field

[0001] This utility model relates to the technical field of vehicle disinfection devices, and in particular to a disinfection device for garbage collection vehicles. Background Technology

[0002] Garbage trucks travel between cities during the waste disposal process, and due to their contact with large amounts of garbage, they can potentially become a source of germs and their spread. To prevent secondary pollution from garbage trucks, disinfection is essential. Disinfection devices typically use physical or chemical methods to thoroughly disinfect and sterilize all parts of the garbage truck, including the body, chassis, and interior, to reduce the risk of germ transmission and ensure hygiene and health.

[0003] Currently, the existing disinfection devices for garbage trucks on the market mainly include: manual high-pressure water gun disinfection and sterilization, and fixed spray frame disinfection. Manual high-pressure water gun disinfection and sterilization involves the operator manually spraying the garbage truck with a high-pressure water gun from all angles. The spray frame arranges a single row of nozzles in a straight line at a height of 2-2.5m, spraying the garbage truck while it is in motion through fixed nozzle positions.

[0004] However, these existing disinfection devices have the following problems:

[0005] 1. Manual disinfection is inefficient, with each operation taking more than 5 minutes. Operators must operate at close range, posing a high risk of exposure to pathogens. Furthermore, manual spraying makes it difficult to ensure uniform atomization, affecting disinfection effectiveness and increasing the risk of cross-infection.

[0006] 2. Due to the limitations of nozzle height and arrangement, the fixed spray rack can only cover the front and side of the vehicle, and cannot disinfect the roof and chassis, resulting in a disinfection coverage rate of less than 60% and more than 40% of the area is untreated. Utility Model Content

[0007] The purpose of this utility model is to provide a disinfection device for garbage collection vehicles to alleviate the technical problems of uneven disinfection and dead corners that cannot be disinfected in the existing technology.

[0008] The present invention provides a disinfection device for a garbage truck, comprising: a deceleration assembly, an arched bracket, a nozzle assembly, a water supply assembly, and a control assembly;

[0009] Deceleration components and arched supports are arranged sequentially along the direction of travel of the waste collection vehicle;

[0010] The nozzle assembly includes top sprayers, side sprayers, and ground sprayers. Multiple top sprayers are arranged in the arc-shaped part of the arched support, with several top sprayers arranged in double rows in an alternating pattern. The distance between two adjacent top sprayers is 0.5m to 0.6m, and the spray angle α of the top sprayers is 85° to 90°. Multiple side sprayers are arranged on the straight parts on both sides of the arched support, with the spray angle β of the side sprayers being 30° to 45°. Several ground sprayers are distributed below the arched support, with the spray angle γ of the ground sprayers being 45° to 50°.

[0011] The top spray, side spray guns and ground spray are all connected to the water supply unit through pipelines, and the control unit is connected to the water supply unit by signal.

[0012] Furthermore, the water supply assembly includes a water tank and a water pump; the water tank is connected to pipelines for storing and supplying disinfectant, and the water pump is installed in the pipelines and is signal-connected to the control assembly.

[0013] Furthermore, the control components include an infrared sensor, a pressure sensor, and a controller;

[0014] An infrared sensor is positioned in front of the deceleration assembly and connected to the controller for signal control of start and stop; a pressure sensor is positioned on the surface of the deceleration assembly and connected to the controller for signal detection of vehicle speed; the output of the controller is connected to a water pump.

[0015] Furthermore, the infrared sensor is fixed by a column, and the height of the infrared sensor is 0.8m to 1m.

[0016] Furthermore, the deceleration assembly consists of three speed bumps, each with a height of 50mm to 60mm and a spacing of 1.2m between adjacent speed bumps.

[0017] Furthermore, the three speed bumps will reduce the speed of garbage trucks to 3km / h to 5km / h.

[0018] Furthermore, the deceleration assembly is a hydraulically lifted road barrier.

[0019] Furthermore, the span of the arched support is 4.2m to 4.5m.

[0020] Furthermore, drainage channels are provided on both sides of the ground below the arched support.

[0021] Beneficial effects:

[0022] This utility model provides a disinfection device for a garbage truck, including a deceleration assembly and an arched support arranged sequentially along the direction of travel of the truck; the nozzle assembly includes top sprayers, side sprayers and ground sprayers, with multiple top sprayers arranged in the arc-shaped part of the arched support, and several top sprayers arranged in double rows in an alternating pattern, with a spacing of 0.5m to 0.6m between two adjacent top sprayers, and the spray angle α of the top sprayers being 85° to 90°; multiple side sprayers are arranged on the straight parts on both sides of the arched support, with a spray angle β of 30° to 45°; several ground sprayers are distributed below the arched support, with a spray angle γ of 45° to 50°; the top sprayers, side sprayers and ground sprayers are all connected to a water supply assembly through pipelines, and the control assembly is signal-connected to the water supply assembly.

[0023] By using a double-row staggered arrangement of top sprayers, side sprayers on both sides, and ground sprayers below, along with their spray angles, the garbage truck is disinfected simultaneously from multiple directions, including the top, sides, and chassis. Compared to traditional methods, this greatly improves the disinfection coverage rate, increasing it from less than 60% to over 98%, effectively eliminating blind spots that cannot be disinfected.

[0024] By setting a deceleration component that is set in the direction of vehicle travel, the vehicle can receive precise disinfection while slowing down, avoiding unnecessary waste of disinfectant. The amount of disinfectant consumed can be reduced to 4L / vehicle to 6L / vehicle, saving 50% compared to traditional solutions.

[0025] In summary, this invention can achieve three-dimensional disinfection and utilize the disinfection linkage of speed bumps to improve coverage and save on the amount of disinfectant consumed. Attached Figure Description

[0037] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] like Figure 1 , Figure 2 As shown, this utility model embodiment provides a disinfection device for a garbage truck, including: a deceleration assembly 1, an arched bracket 2, a nozzle assembly 3, a water supply assembly 4, and a control assembly 5;

[0039] Deceleration assembly 1 and arched support 2 are arranged sequentially along the direction of travel of the garbage truck;

[0040] The nozzle assembly 3 includes a top spray 301, side spray guns 302, and a ground spray 303. Multiple top sprays 301 are arranged in the arc-shaped part of the arched support 2, and the top sprays 301 are arranged in double rows in an alternating manner. The distance between two adjacent top sprays 301 is 0.5m to 0.6m, and the spray angle α of the top spray 301 is 85° to 90°. Multiple side spray guns 302 are arranged on the straight parts on both sides of the arched support 2, and the spray angle β of the side spray guns 302 is 30° to 45°. Multiple ground sprays 303 are distributed below the arched support 2, and the spray angle γ of the ground spray 303 is 45° to 50°.

[0041] The top sprayer 301, the side sprayer 302 and the ground sprayer 303 are all connected to the water supply component 4 through pipelines, and the control component 5 is connected to the water supply component 4 by signal.

[0042] Specifically, the deceleration assembly 1 is positioned on the ground in front of the arched support 2, where spraying begins. When a garbage truck passes the deceleration assembly 1, the vehicle is forced to slow down, ensuring sufficient time for comprehensive and effective disinfection during subsequent processes. Simultaneously, the control assembly 5 within the deceleration bump monitors the vehicle speed in real time. If the speed exceeds 8 km / h, an alarm signal is issued to alert the driver to abnormal speed, ensuring the safety and effectiveness of the disinfection process. The arched support 2 has an arched cross-section, with two curved top sections and corresponding straight sections on both sides. A connecting rod connects the two curved top sections, providing support for the nozzle assembly 3. The straight sections of the arched support 2 are fixed to the ground behind the deceleration assembly 1. The arched shape allows for support of the nozzle assembly 3 without obstructing the normal passage of the garbage truck.

[0043] Multiple top sprayers 301 in the nozzle assembly 3 are arranged in a double-row staggered pattern on the arc-shaped part of the arched support 2. That is, the projected position of the top sprayer 301 on the latter arc-shaped part is between the two top sprayers 301 on the former arc-shaped part. Preferably, there are 5 top sprayers 301 in each row. The distance between two adjacent top sprayers 301 is between 0.5m and 0.6m, and the spray angle α of the top sprayer 301 is between 85° and 90°. Side spray guns 302 are arranged on the straight parts on both sides of the arched support 2, with multiple side spray guns 302 arranged on each side. Preferably, there are two side spray guns 302 on each side. The spray angle β of the side spray guns 302 is in the range of 30° to 45°. Several ground sprayers 303 are pre-embedded and distributed under the arched support 2. The spray angle γ of the ground sprayers 303 is between 45° and 50°. The top sprayers 301, side spray guns 302, and ground sprayers 303 are all connected to the water supply assembly 4 through pesticide spraying pipelines. The top sprayer 301, side sprayers 302, and ground sprayers 303 simultaneously disinfect the vehicle's top, sides, and chassis, creating a three-dimensional disinfection space. The top sprayer 301 disinfects the vehicle's top, with its double-row staggered arrangement and appropriate spray angle ensuring comprehensive coverage. The side sprayers 302 disinfect the vehicle's sides, and the ground sprayer 303 disinfects the vehicle's chassis. Its upward spray angle ensures that all parts of the chassis receive the disinfectant, significantly improving the disinfection coverage from less than 60% to over 98%, eliminating any blind spots.

[0044] It should be noted that the top spray 301, side spray gun 302 and ground spray 303 can all be set to self-clean the nozzles, that is, to perform a 10-second air backflushing after each disinfection.

[0045] The water supply component 4 stores the disinfectant in a tank, extracts and pressurizes it, and then transmits it through branching channels resembling tree branches to the top sprayer 301, side sprayers 302, and ground sprayers 303, thus achieving water supply. The control component 5 detects vehicle entry and speed. When a vehicle enters the disinfection area and reaches the appropriate speed, the water supply component 4 is activated, causing the spray nozzles to begin disinfection. The entire control process uses a hard-wired system, eliminating reliance on complex software and reducing the risk of software failure. This invention has undergone 2000 continuous operation tests, achieving a system reliability of 99.6%, ensuring stable operation and precise control of the disinfection device.

[0046] In embodiments of this utility model, such as Figure 2 As shown, the water supply component 4 includes a water supply tank 401 and a water pump 402; the water supply tank 401 is connected to the pipeline and is used to store and supply disinfectant; the water pump 402 is installed in the pipeline and is connected to the control component 5 via signal.

[0047] like Figure 3 As shown, the control component 5 includes an infrared sensor 501, a pressure sensor 502, and a controller 503. The infrared sensor 501 is located in front of the deceleration component 1 and is connected to the controller 503 for signal control of start and stop. The pressure sensor 502 is located on the surface of the deceleration component 1 and is connected to the controller 503 for signal detection of vehicle speed. The output of the controller 503 is connected to a water pump 402. The infrared sensor 501 is fixed by a column, and its height is 0.8m to 1m.

[0048] Specifically, the infrared sensor 501 is a conventional infrared sensor. When the sensing element detects a vehicle, it emits an infrared signal. The detected signal is amplified, filtered, and converted into an electrical signal that the controller 503 can recognize. The infrared sensor 501 is fixed to the front of the reduction assembly 1 by a pole, maintaining a height between 0.8m and 1m to detect vehicles and prevent the disinfection assembly from failing to detect vehicles due to the height being too low. The infrared sensor 501 is connected to the controller 503 via a wire to realize automatic start-stop function, avoiding cumbersome manual operation, improving work efficiency, and reducing unnecessary energy consumption and chemical waste.

[0049] The pressure sensor 502 is a conventional piezoresistive type. Its sensitive element detects pressure changes on the surface of the deceleration assembly 1 as the vehicle passes through, converting this pressure into an electrical signal that the controller 503 can recognize. By monitoring pressure changes in real time as the vehicle passes through the deceleration assembly 1, and considering that pressure changes are related to vehicle speed, the controller 503 can calculate the vehicle's speed based on the signal transmitted by the pressure sensor 502. When the vehicle speed exceeds a set threshold (e.g., 8 km / h), the controller 503 issues an alarm signal to remind the driver to slow down, ensuring effective disinfection.

[0050] The input terminal of the controller 503 is connected to the infrared sensor 501 and the pressure sensor 502 respectively through signal lines to receive the transmitted signals; the output terminal is connected to the water pump 402 to send control commands to the water pump 402.

[0051] Control component 5 works in conjunction with deceleration component 1 and water supply component 4 to automate the disinfection process of the garbage truck, improve disinfection efficiency, reduce waste of disinfectant and labor costs, and enhance the reliability and safety of the system.

[0052] In one embodiment of this utility model, as a method of implementing a speed reduction component 1, the speed reduction component 1 consists of three speed bumps, each with a height of 50mm to 60mm and a spacing of 1.2m between adjacent speed bumps. These three speed bumps reduce the speed of the garbage truck to 3km / h to 5km / h.

[0053] Specifically, the deceleration assembly 1 consists of three speed bumps arranged sequentially along the direction of travel of the garbage truck. This is to cause the vehicle to undergo multiple deceleration processes when passing over them, thereby reducing the vehicle speed. The speed bumps are low in cost and easy to maintain.

[0054] Each speed bump is between 50mm and 60mm high, effectively slowing down vehicles without causing excessive bumps or damage. The spacing between adjacent speed bumps is 1.2m, allowing vehicles a suitable buffer distance after passing one speed bump before smoothly reducing speed to the next. Passing through three speed bumps can stably reduce the garbage truck's speed to 3km / h to 5km / h. This speed range facilitates subsequent disinfection; the reduced speed allows the nozzle assembly 3 sufficient time for comprehensive and thorough disinfection, thereby improving the effectiveness and coverage of the disinfection.

[0055] As another implementation of the deceleration component 1, the deceleration component 1 is a hydraulic lifting road barrier, which can force a stop and is safer.

[0056] In this embodiment of the invention, the span of the arched support 2 is 4.2m to 4.5m. Drainage channels 6 are provided on both sides of the ground below the arched support 2.

[0057] Based on the above embodiments, the working process of the disinfection device for the garbage truck provided by this utility model is as follows:

[0058] The garbage truck drives towards the disinfection area, first passing through speed reduction assembly 1. If speed reduction assembly 1 consists of three speed bumps spaced 1.2m apart, the vehicle speed will be reduced. Simultaneously, the infrared sensor 501 located in front of speed reduction assembly 1 detects the vehicle's entry and quickly transmits a signal to the controller 503. Upon receiving the signal from the infrared sensor 501 and confirming that the vehicle speed meets the requirements, the controller 503 sends a start command to the water pump 402 in the water supply assembly 4. The water pump 402 starts, drawing and pressurizing disinfectant from the water supply tank 401, and then delivering the disinfectant through pipelines to the top sprayer 301, side sprayers 302, and ground sprayers 303, respectively, for comprehensive disinfection of the roof, body, and chassis.

[0059] The disinfection device for garbage trucks provided by this utility model increases the coverage rate from 60% to 98%. With the deceleration component 1 and its control, the consumption of disinfectant is reduced to 4-6L per truck.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
