Description

Technical Field

[0001] This utility model relates to the field of chassis cleaning technology, specifically to an automatic spray disinfection device for the chassis of vehicles at the entrance of a goose farm. Background Technology

[0002] With the rapid development of modern large-scale farming, farms are facing increasingly stringent requirements for disease prevention. Vehicles, as a major route for pathogen transmission, require thorough disinfection of their chassis to prevent the spread of disease. Traditional vehicle disinfection methods mainly rely on fixed spray equipment or manual hand-held sprayers, which have significant limitations. Fixed spray devices cannot flexibly adapt to the chassis height and structure of different vehicle models, easily leaving disinfection dead spots and resulting in incomplete disinfection. Manual operation is inefficient, and the disinfection effect is difficult to guarantee. It also poses a risk of personnel contact. Moreover, most existing equipment lacks wastewater recycling and treatment functions, and the disinfection waste liquid after spraying is directly discharged, which not only wastes disinfectant and water resources but may also cause chemical pollution to the farm area and surrounding environment. Therefore, there is room for improvement. Utility Model Content

[0003] To address the problems mentioned in the background section, this application provides an automatic spray disinfection device for the chassis of vehicles entering a goose farm.

[0004] The automatic spray disinfection device for vehicle chassis at the entrance of a goose farm provided in this application adopts the following technical solution:

[0005] An automatic spray disinfection device for vehicle chassis at the entrance of a goose farm includes a mechanical structure system, a spray system, an intelligent control system, and a wastewater recovery system. The mechanical structure system includes a buried spray unit, a lifting drive mechanism, and a swing drive mechanism. The spray system includes a liquid preparation tank, a high-pressure pump, and nozzles. The nozzles are installed on the buried spray unit. The intelligent control system is electrically connected to the lifting drive mechanism, the swing drive mechanism, and the high-pressure pump to control the movement of the buried spray unit and the start and stop of the spray system. The wastewater recovery system is located below the buried spray unit to collect and treat the waste liquid after spraying.

[0006] By adopting the above-mentioned technical solutions, fully automatic, efficient, and three-dimensional spray disinfection of the chassis of vehicles entering the site is achieved. The underground design, combined with the lifting and swinging mechanism, allows the spraying unit to be hidden underground when not in operation, avoiding damage from being run over and keeping the site clean. During operation, the flexible lifting and swinging mechanism allows the disinfectant to fully cover the complex structure of the chassis of different vehicle models, with no blind spots in disinfection. The intelligent control system automatically identifies vehicles and triggers the disinfection process through sensors and machine vision, without the need for manual intervention, thus improving disinfection efficiency and reliability. The wastewater recycling system realizes the collection, filtration, and recycling of disinfection waste liquid, which not only saves disinfectant and water resources, but also avoids the pollution of the site environment by chemical waste liquid, meeting the dual requirements of epidemic prevention and environmental protection in modern farms.

[0007] Optionally, the buried spray unit includes a liftable column and a spray arm mounted on the column. The lifting drive mechanism is used to drive the column to rise and fall, and the swing drive mechanism is used to drive the spray arm to swing back and forth.

[0008] By adopting the above technical solution, the vertical movement of the lifting column and the horizontal swing of the spray arm achieve adaptive coverage of the vehicle chassis height and contour. The lifting function ensures that vehicles with different chassis heights can obtain the optimal spray distance and impact force, while the reciprocating swing of the arm expands the lateral coverage of the spray, effectively cleaning complex structures such as chassis longitudinal beams and tire inner sides, avoiding disinfection blind spots present with fixed nozzles, and allowing the disinfectant to be sprayed evenly onto the chassis surface at the optimal angle and pressure, significantly improving the thoroughness and efficiency of disinfection. At the same time, the underground structure can be completely retracted when not in operation, ensuring smooth traffic flow and equipment safety in the site.

[0009] Optionally, the buried spray unit is provided with a waterproof cover plate. When not in operation, the waterproof cover plate is in a closed state, enclosing the buried spray unit inside.

[0010] By adopting the above technical solution, the waterproof cover forms a sealed protective space when not in operation, effectively preventing dust, debris, rainwater or surface wash water from entering the underground spray unit. This avoids damage to precision components such as the lifting mechanism and nozzles due to pollution, corrosion or freezing, significantly improving the reliability and service life of the equipment. When closed, the cover is flush with the ground, maintaining the integrity and aesthetics of the site while ensuring unobstructed vehicle passage and avoiding interference with daily traffic operations.

[0011] Optionally, there are multiple nozzles, which are distributed and fixed on the spray arm at a preset interval.

[0012] By adopting the above technical solution, multiple nozzles are distributed on the spray arm at a preset interval to form a spray array with a wide coverage and uniform spray density, which can simultaneously disinfect different areas of the vehicle chassis without dead angles.

[0013] Optionally, the spray system further includes a self-cleaning unit, which includes a clean water pipeline and a control valve. The clean water pipeline is connected to the water inlet passage of the nozzle, and the control valve is electrically connected to the intelligent control system.

[0014] By adopting the above technical solution, the self-cleaning unit automatically starts after the disinfection operation is completed through the intelligent control system. It uses the clean water pipeline to rinse the inside of the nozzle, effectively removing residual disinfectant crystals, impurities or precipitates, preventing nozzle blockage or corrosion, and significantly improving the reliability and service life of the spray system.

[0015] Optionally, the intelligent control system includes a main controller, a first sensor, and a machine vision unit. The first sensor is used to sense the entry of a vehicle, and the machine vision unit is used to identify the vehicle type. The main controller is connected to the first sensor, the machine vision unit, the lifting drive mechanism, the swing drive mechanism, and the high-pressure pump signal respectively.

[0016] By adopting the above technical solutions, the intelligent control system realizes fully automated disinfection process control. The first sensor senses the vehicle entry signal in real time, the machine vision unit accurately identifies the vehicle type and chassis structure characteristics, and the main controller intelligently adjusts the height of the lifting drive mechanism, the angle of the swing drive mechanism, and the spray parameters of the high-pressure pump based on this information, so that the disinfection operation can adapt to the chassis characteristics of different vehicle models and achieve precise and efficient spray disinfection.

[0017] Optionally, the wastewater recycling system includes a wastewater collection tank, a filtration unit, and a circulation pump. The wastewater collection tank is located below the buried spray unit. The input end of the filtration unit is connected to the wastewater collection tank. The input end of the circulation pump is connected to the output end of the filtration unit. The output end of the circulation pump is connected to the liquid preparation tank of the spray system.

[0018] By adopting the above technical solutions, the wastewater recycling system realizes the automated collection, treatment and recycling of disinfection waste liquid. The wastewater collection tank effectively collects the residual liquid after spraying. After the filtration unit removes impurities and pollutants, the purified liquid is transported back to the liquid preparation tank by the circulation pump, forming a closed-loop resource recycling system. This significantly reduces the consumption of disinfectant and the use of fresh water, saves operating costs, and embodies the green and environmentally friendly design concept.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. Through the synergistic effect of the underground spray unit and the intelligent control system, fully automatic and thorough disinfection of the chassis of various vehicles can be achieved;

[0021] 2. The waterproof cover and self-cleaning unit effectively protect the core components from environmental influences and maintain the long-term stable operation of the system, reducing maintenance costs;

[0022] 3. Through the closed-loop design of the wastewater recycling system, the disinfection waste liquid can be purified and reused, which can significantly reduce resource consumption and environmental pollution while ensuring the effectiveness of epidemic prevention, demonstrating good economic and environmental benefits.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses an automatic spray disinfection device for the chassis of a vehicle at the entrance of a goose farm.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The mechanical structure system 1 of the device adopts an underground design. The underground spray unit 10 consists of a liftable lifting column 101 and a spray arm 102. The lifting column 101 is made of 304 stainless steel with a diameter of 80mm to ensure load-bearing capacity and corrosion resistance. The spray arm 102 is made of the same material and is welded to the top of the lifting column 101. The two form a coordinated structure of "vertical lifting + horizontal spraying". The base of the lifting drive mechanism 11 is fixed in the underground pre-set concrete foundation with expansion bolts. The output shaft is rigidly connected to the bottom flange of the lifting column 101, driving the lifting column 101 to achieve a stroke adjustment of 0.3-1.2m in the vertical direction, adapting to different models from cars (chassis height 12-18cm) to small trucks (chassis height 30-60cm); the swing drive mechanism 12 drives... The spray arm 102 can reciprocate from 0 to 60°, expanding the lateral spray coverage. At the top of the buried spray unit 10, a waterproof cover plate 13 made of cast iron is connected by a hinge. The cover plate is 10mm thick and equipped with a spring return assembly at the bottom. When the lifting drive mechanism 11 drives the lifting column 101 to rise, the lifting column 101 pushes open the waterproof cover plate 13 through the linkage mechanism, allowing it to slide open to both sides. When the disinfection operation is completed, when the lifting drive mechanism 11 drives the lifting column 101 to fall and return to its original position, the connection between the linkage mechanism and the waterproof cover plate 13 is released. Under the action of the built-in return spring, the cover plate automatically rotates back to the closed state, returning to the ground level, completely enclosing the buried spray unit 10 and preventing mud, sand, and rainwater from entering the tank. During operation, the lifting column 101 rises to lift the cover plate, ensuring the normal operation of the spray arm 102.

[0031] The liquid preparation tank 20 of the spray system 2 is a 200L stainless steel tank, placed in the equipment room next to the disinfection channel. The bottom outlet of the tank is connected to the inlet of the high-pressure pump 21 via a PVC hose with a filter screen. The high-pressure pump 21 is a 4kW chemical-specific pump with an output pressure adjustable between 0.4-0.8MPa. The outlet is sealed to the inlet of the liquid delivery chamber of the spray arm 102 via a high-pressure steel wire hose, forming a "liquid storage-pressurization-transportation" fluid channel. A nozzle 22 mounting hole is pre-set every 15cm along the length of the spray arm 102. Each mounting hole is connected to a nozzle 22 via a thread. The diameter of the atomized particles is controlled at 15-30μm. The water inlet passage is directly connected to the infusion chamber inside the support arm. Multiple nozzles 22 form a uniform spray array to ensure that the disinfectant can fully cover the vehicle chassis. The spray system 2 is also equipped with a self-cleaning unit 23, which consists of a clean water pipe 231 and a control valve 232. One end of the clean water pipe 231 is connected to an external clean water source, and the other end is connected to the high-pressure pump 21 to the high-pressure hose of the spray support arm 102. The control end of the control valve 232 is connected to the intelligent control system 3 through a signal line. It automatically opens after disinfection to rinse the disinfectant residue inside the nozzles 22 with clean water.

[0032] The intelligent control system 3 uses a PLC as the main controller 30, which is installed in the control box in the equipment room. The first sensor 31 is fixed on the column on the left side of the entrance to the disinfection channel, at a height of 1.2m, for real-time sensing of vehicle entry. The machine vision unit 32 consists of a high-definition industrial camera and an image recognition module. The camera is installed on the bracket on the right side of the entrance to the channel, with the lens facing the direction of vehicle travel, to capture images of the side of the vehicle. The image recognition module communicates with the main controller 30 via Ethernet and can accurately identify the vehicle type and chassis height with an accuracy rate of no less than 98%. The main controller 30 is connected to the control valves 232 of the lifting drive mechanism 11, the swing drive mechanism 12, the high-pressure pump 21, and the self-cleaning unit 23 via control lines. It receives the trigger signal from the first sensor 31 and the recognition result from the machine vision unit 32, and then generates corresponding control commands. When a large truck is detected, the lifting column 101 is raised to a height of 0.6m, the swing angle of the spray arm 102 is adjusted to 60°, and the pressure of the high-pressure pump 21 is set to 0.7MPa to ensure that the disinfectant can penetrate the chassis gaps.

[0033] The wastewater collection tank 40 of the wastewater recycling system 4 is an underground concrete structure located directly below the buried spray unit 10. The top of the tank is connected to the bottom of the buried trench through a guide hole. The waste liquid generated during the disinfection process and the rinsing water during the self-cleaning stage flow into the collection tank by gravity. The outlet of the collection tank is connected to the input end of the filter unit 41. The filter unit 41 adopts a three-stage filtration structure of "grid + quartz sand + activated carbon". It first removes large particulate impurities in the waste liquid, then filters fine suspended solids and adsorbs odors. The filtered clean water is transported to the inlet of the circulation pump 42 through a pipeline. The circulation pump 42 is a centrifugal pump with a power of 1.5kW. The output end is connected to the liquid preparation tank 20 of the spray system 2 through a pipeline to realize the purification and reuse of waste liquid and form a closed loop of resource recycling.

[0034] In actual use, when a vehicle enters the disinfection channel at the entrance of the goose farm, the first sensor 31 detects the vehicle and transmits the signal to the main controller 30. The main controller 30 immediately activates the machine vision unit 32 to capture an image of the vehicle and identify the vehicle type and chassis parameters. Subsequently, based on the identification results, it controls the lifting drive mechanism 11 to drive the lifting column 101 to the appropriate height, while the swing drive mechanism 12 drives the spray arm 102 to adjust its initial angle. During the ascent of the lifting column 101, the waterproof cover 13 is lifted. After the mechanical structure is adjusted to the correct position, the main controller 30 starts the high-pressure pump 21. The disinfectant in the liquid preparation tank 20 is pressurized and then transported through pipelines to the spray arm 102, where it is atomized and sprayed out by multiple nozzles 22. At the same time, the swing drive mechanism... The mechanism 12 drives the spray arm 102 to swing back and forth, achieving full-area disinfection of the vehicle chassis. After the vehicle leaves the passage, the first sensor 31 detects the departure signal, and the main controller 30 shuts down the high-pressure pump 21 and the swing drive mechanism 12, controls the lifting column 101 to descend to the initial position, and the waterproof cover 13 closes under the action of the spring. Then, the main controller 30 opens the control valve 232 of the self-cleaning unit 23, and the clean water rinses the nozzle 221 for 2 minutes and then closes. The rinsing water and disinfection waste liquid flow into the wastewater collection tank 40 together. When the liquid level in the collection tank reaches the preset height, the main controller 30 starts the circulation pump 42 to deliver the clean water purified by the filtration unit 41 to the liquid preparation tank 20, completing a complete disinfection and resource recycling process.

[0035] The implementation principle of the automatic spray disinfection device for vehicle chassis at the entrance of a goose farm according to an embodiment of this application is as follows:

[0036] With the intelligent control system 3 as the core, the three major systems are linked to achieve fully automated disinfection and resource recycling. When a vehicle enters the site, the first sensor 31 triggers the machine vision unit 32 to identify the vehicle model and chassis parameters and transmit them to the main controller 30. The main controller 30 drives the lifting column 101 to rise and lift the waterproof cover 13 to the appropriate height. At the same time, it adjusts the initial angle of the spray arm 102 and then starts the high-pressure pump 21. The disinfectant in the liquid preparation tank 20 is pressurized and then atomized and sprayed out from the nozzle 22 of the spray arm 102. The arm swings back and forth to achieve no dead angle coverage of the chassis. After the vehicle leaves the site, the main controller 30 shuts off the spray and swing mechanism, the lifting column 101 descends, the waterproof cover 13 closes, and the self-cleaning unit 23 rinses the nozzle 22 after disinfection. The disinfection waste liquid and rinsing water flow into the wastewater collection tank 40 and are purified by the filtration unit 41. The purified water is transported to the liquid preparation tank 20 for reuse by the circulation pump 42, completing the complete operation of "sensing-disinfection-cleaning-recycling" while taking into account both epidemic prevention and resource conservation.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
