Abstract
Description
Technical Field
[0001] This application relates to the field of waste treatment technology, and in particular to a mosquito and fly control device and spray control method for waste storage pits. Background Technology
[0002] Waste incineration is a relatively traditional method of waste disposal. Because incineration significantly reduces waste volume, saves land, eliminates pathogens, and transforms toxic and harmful substances into harmless ones, it has become one of the primary methods of urban waste management. Furthermore, waste-to-energy plants are generally open to the public, projecting an environmentally friendly and harmless image. The waste storage pit is where waste-to-energy plants store and ferment waste. Household waste is collected from various parts of the city and gathered in the storage pit. After 3-7 days of fermentation, the moisture in the waste is filtered out, the calorific value of the waste increases, and it becomes easier to incinerate. To ensure sufficient storage space and fermentation time, the design capacity of the waste storage pit in a waste-to-energy plant is generally more than 10 times the incineration capacity. Waste-to-energy plants with a processing capacity of 2000 tons / day or more typically have a waste storage pit design capacity of over 40,000 m³, and the cross-sectional area of the storage pit is also relatively large.
[0003] Currently, during the waste fermentation process, the complex composition of waste results in a large amount of perishable substances, creating ideal breeding grounds for flies and mosquitoes. This not only affects the environmental hygiene of waste-to-energy plants but also easily spreads viruses, endangering public health. Existing technologies, due to the large volume and area of waste storage pits, primarily address the problem of flies and mosquitoes in waste-to-energy plants by using isolation methods. This involves using double-glazed windows to separate the viewing passages from the storage pits and using unloading doors to separate the storage pits from the unloading hall, preventing flies and mosquitoes from spilling out and affecting the public environment. However, because flies and mosquitoes reproduce rapidly within the storage pits, isolation methods are not effective in eliminating them. Furthermore, the isolated flies and mosquitoes continue to roam freely within the storage pits, negatively impacting the environmental image of the waste-to-energy plant. Summary of the Invention
[0004] The purpose of this application is to at least solve one of the above-mentioned technical defects, especially the technical defect that the existing technology cannot effectively eliminate flies and mosquitoes by means of isolation because the breeding rate of pests such as flies and mosquitoes in the garbage storage pit is relatively fast, and the isolated flies and mosquitoes fly around in the garbage storage pit, which will also affect the environmental image of the waste incineration power plant.
[0005] This application provides a device for controlling mosquitoes and flies in a garbage storage pit, the device comprising a lime powder conveying unit, a lime powder spraying unit, and a spraying control system;
[0006] The output end of the lime powder conveying unit is connected to the input end of the lime powder spraying unit, and the output end of the lime powder spraying unit is connected to the spraying control system.
[0007] The lime powder conveying unit sprays lime powder onto the lime powder spraying unit by pneumatic conveying. The lime powder spraying units are evenly distributed on the walls around the garbage storage pit.
[0008] After the spraying control system collects the location information of the garbage crane and the opening and closing status of the garbage grab, it determines the target area in the garbage storage pit that needs to be sprayed with lime based on the location information and the opening and closing status. When it is determined that the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, it controls the lime powder spraying unit to spray lime powder onto the garbage in the target area.
[0009] Optionally, the lime powder conveying unit includes a lime storage bin, a lime rotary feeder valve, a lime weighing feeder bin, and a lime screw feeder valve connected in sequence in a first direction, and a Roots blower and a Venturi jet pipe connected in sequence in a second direction perpendicular to the first direction, wherein the bottom of the lime screw feeder valve is connected through the top of the Venturi jet pipe.
[0010] The lime rotary feeder valve replenishes the lime weighing feed hopper according to the real-time weight of the lime weighing feed hopper;
[0011] The lime screw feeder valve is used to control the feeding speed of the lime weighing feeder hopper;
[0012] The Roots blower is used to input high-pressure air into the Venturi injection pipe, so that after the Venturi injection pipe is located at the bottom area of the lime screw feeder valve and forms a negative pressure zone, the lime powder in the negative pressure zone is sucked into the Venturi injection pipe and transported to the input end of the lime powder injection unit along with the high-pressure air.
[0013] Optionally, the lime powder spraying unit includes a lime spraying pipe network installed on the perimeter wall around the garbage storage pit, and electric butterfly valves evenly distributed on the lime spraying pipe network.
[0014] Each electric butterfly valve has a spray nozzle corresponding to the waste in a specific area within the waste storage pit.
[0015] Optionally, the spraying control system includes a data acquisition unit, a central processing unit, a lime pipeline electric butterfly valve controller, and a memory. The lime powder spraying unit includes electric butterfly valves evenly distributed on the walls around the garbage storage pit. The lime pipeline electric butterfly valve controller is electrically connected to each electric butterfly valve.
[0016] The data acquisition unit is used to collect and send the location information of the garbage crane, the opening and closing status of the garbage grab bucket, and the opening and closing status of each electric butterfly valve to the central processing unit.
[0017] The memory is used to store the position information of each electric butterfly valve after being encoded according to the plane coordinate system of the waste storage area;
[0018] The central processing unit is used to select the target electric butterfly valve that is closest to the garbage grab bucket based on the position information of the garbage crane and the position information of each electric butterfly valve. When it is detected that the opening and closing state of the garbage grab bucket meets the preset action, and it is determined that the lime powder conveying unit is in the start state and the target electric butterfly valve is in the closed state, it sends an instruction to open the electric butterfly valve to the lime network electric butterfly valve controller.
[0019] The lime pipeline electric butterfly valve controller is used to open the target electric butterfly valve at the corresponding location according to the electric butterfly valve opening command, so as to spray lime powder onto the garbage in the corresponding area through the target electric butterfly valve.
[0020] Optionally, the electric butterfly valve controller for the limestone pipeline network is also used for:
[0021] After the central processing unit stops sending the command to open the electric butterfly valve, the target electric butterfly valve is closed after a delay.
[0022] Optionally, the central processing unit is further configured to:
[0023] When the opening and closing state of the garbage grab bucket does not conform to the preset action, no instruction is sent to the electric butterfly valve controller of the lime pipeline network.
[0024] This application also provides a spray control method for a mosquito and fly control device for a garbage storage pit, applied to the spray control system in the mosquito and fly control device for a garbage storage pit as described in any of the above embodiments, the method comprising:
[0025] Collect the location information of the garbage crane and the opening and closing status of the garbage grab bucket;
[0026] Based on the location information and the opening / closing state, determine the target area within the waste storage pit where lime needs to be sprayed;

[0028] Optionally, the lime powder spraying unit includes electrically operated butterfly valves evenly distributed on the perimeter walls around the waste storage pit;
[0029] Determining the target area within the waste storage pit that needs to be sprayed with lime based on the location information and the opening / closing state includes:
[0030] Obtain the pre-stored position information of each electric butterfly valve after it has been encoded according to the plane coordinate system of the waste storage area;
[0031] Based on the location information of the garbage crane and the location information of each electric butterfly valve, select the target electric butterfly valve that is closest to the garbage grab bucket;
[0032] Determine whether the opening and closing state of the garbage grab bucket conforms to the preset action;
[0033] If the conditions are met, the area corresponding to the injection port of the target electric butterfly valve will be taken as the target area in the waste storage pit where lime needs to be sprayed.
[0034] If it does not meet the requirements, then it is determined that lime does not need to be sprayed in the current waste storage pit.
[0035] Optionally, when the operating states of the lime powder conveying unit and the lime powder spraying unit meet preset conditions, controlling the lime powder spraying unit to spray lime powder onto the garbage in the target area includes:
[0036] Determine if the lime powder conveying unit is in the start-up state;
[0037] If it is in the start state, determine whether the target electric butterfly valve is in the closed state;
[0038] If it is in the closed state, the target electric butterfly valve is opened, and lime powder is sprayed onto the garbage in the target area through the target electric butterfly valve;
[0039] If not in the closed state, lime powder will continue to be sprayed onto the garbage in the target area through the target electric butterfly valve;
[0040] If it is not in the start state, after starting the lime powder conveying unit, return to the process of determining whether the target electric butterfly valve is in the closed state and the subsequent steps.
[0041] Optionally, the method further includes:
[0042] If it is determined that the opening and closing state of the garbage grab does not conform to the preset action, and the target electric butterfly valve is still in the open state, the target electric butterfly valve is closed after a delay.
[0043] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:
[0044] This application provides a mosquito and fly control device and spraying control method for a garbage storage pit. The device includes a lime powder conveying unit, a lime powder spraying unit, and a spraying control system. The output end of the lime powder conveying unit is connected to the input end of the lime powder spraying unit, and the output end of the lime powder spraying unit is connected to the spraying control system. In this way, the lime powder conveying unit can pneumatically convey lime powder to the lime powder spraying unit, which is evenly distributed on the walls surrounding the garbage storage pit. It can precisely spray the garbage in different areas of the pit, thus utilizing the insect-killing principle of lime (lime reacts with water). The system achieves insect control by utilizing the chemical reactions that occur, the bactericidal effect of the generated calcium hydroxide, and the physical and chemical properties of lime itself, while also saving lime. Specifically, after the spray control system of this application collects the location information of the garbage crane and the opening and closing status of the garbage grab, it can determine the target area in the garbage storage pit that needs to be sprayed with lime based on the location information and the opening and closing status. When the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, the system controls the lime powder spraying unit to spray lime powder onto the garbage in the target area, thereby efficiently and accurately eliminating mosquitoes and flies and maintaining the environmental image of the waste incineration power plant.

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0053] In one embodiment, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a mosquito and fly control device for a garbage storage pit provided in an embodiment of this application. This application provides a mosquito and fly control device for a garbage storage pit, which includes a lime powder conveying unit, a lime powder spraying unit, and a spraying control system.
[0054] The output end of the lime powder conveying unit is connected to the input end of the lime powder spraying unit, and the output end of the lime powder spraying unit is connected to the spraying control system.
[0055] The lime powder conveying unit sprays lime powder onto the lime powder spraying unit via pneumatic conveying. The lime powder spraying units are evenly distributed on the perimeter wall 7 around the garbage storage pit.
[0056] After the spraying control system collects the position information of the garbage crane 10 and the opening and closing status of the garbage grab bucket 11, it determines the target area in the garbage storage pit that needs to be sprayed with lime based on the position information and the opening and closing status. When it is determined that the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, it controls the lime powder spraying unit to spray lime powder onto the garbage in the target area.
[0057] In this embodiment, when eliminating mosquitoes and flies in the garbage storage pit, lime can be used for insect control. Specifically, this application can form a mosquito and fly control device for the garbage storage pit by constructing a lime powder conveying unit, a lime powder spraying unit, and a spraying control system. The output end of the lime powder conveying unit can be connected to the input end of the lime powder spraying unit, and the output end of the lime powder spraying unit can be connected to the spraying control system. In this way, the spraying control system can collect the position information of the garbage crane 10 and the opening and closing state of the garbage grab bucket 11. After determining the target area in the garbage storage pit that needs to be sprayed with lime based on the collected position information of the garbage crane 10 and the opening and closing state of the garbage grab bucket 11, it is determined whether the working state of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions. If the preset conditions are met, the spraying control system can directly control the lime powder spraying unit to spray lime powder onto the garbage in the target area. If the preset conditions are not met, the working state of the lime powder conveying unit and the lime powder spraying unit can be adjusted to meet the preset conditions before controlling the lime powder spraying unit to spray lime powder onto the garbage in the target area.
[0058] It is understandable that the principle behind lime's insecticidal effect mainly includes the following points:
[0059] 1. Quicklime reacts with water: When quicklime (calcium oxide) comes into contact with water, it undergoes a chemical reaction to produce calcium hydroxide and release a large amount of heat. This chemical reaction not only generates high temperatures but also creates a high-humidity environment, thereby killing mosquito and fly larvae.
[0060] 2. The bactericidal effect of calcium hydroxide: The calcium hydroxide (hydrated lime) produced is highly alkaline, which can increase the pH value of the environment. The released hydroxide ions have a strong bactericidal effect and can effectively kill bacteria, fungi, viruses and pests.
[0061] 3. Damage to the body surface and cell membrane of pests: The hydroxyl and oxidizing components in lime will rapidly oxidize and decompose the fat and protein on the body wall and cell membrane of pests, damaging their metabolic function and body structure.
[0062] 4. Corrosive effect: Lime has a corrosive effect on the skin and scales of pests, which can destroy the physiological structure of pests and lead to their death.
[0063] 5. Dehydration effect: Lime can absorb water from the bodies of mosquito and fly larvae, causing the larvae to dehydrate and die.
[0064] In summary, the insecticidal effect of lime is achieved through a combination of the chemical reaction between lime and water, the bactericidal effect of the generated calcium hydroxide, and the physical and chemical properties of lime itself.
[0065] This application uses a lime powder conveying unit to transport the generated lime powder to a lime powder spraying unit via pneumatic conveying. The lime powder spraying unit can be evenly distributed on the perimeter wall 7 around the garbage storage pit. After the output end of the lime powder spraying unit is connected to the spraying control system, the spraying control system can activate the spraying components installed in the target area of the lime powder spraying unit to evenly spray the lime powder onto the garbage surface in the target area after determining the target area where lime needs to be sprayed in the garbage storage pit.
[0066] It should be noted that, due to the large cross-sectional area of the waste storage pit and the fact that the waste does not need to be turned over during fermentation, once the waste in the fermentation zone is piled up and a layer of lime is sprayed onto the surface, a protective lime layer exists on the surface of the waste. If the waste in the fermentation zone is not turned over, this protective lime layer will function properly, and there is no need to repeat the lime spraying disinfection in that area. When the waste grabber picks up the waste, the lime protective layer on the surface of the waste is destroyed. At this time, the lime powder spraying unit can be controlled by the spraying control system of this application to spray lime on the corresponding area of waste for protection, thereby preventing the breeding of mosquitoes and flies.
[0067] Furthermore, since the location information of the garbage crane 10 and the opening / closing state of the garbage grab bucket 11 change continuously as the garbage cleaning work progresses, this application can first obtain the location information of the garbage crane 10 and the opening / closing state of the garbage grab bucket 11 when determining whether there is a target area in the garbage storage pit that needs to be sprayed with lime. This allows for the determination of the lime powder spraying unit at the corresponding position on the perimeter wall 7 of the garbage storage pit and the targeted garbage area using the location information of the garbage crane 10, and also allows for the determination of whether garbage is being grabbed or scattered in that garbage area using the opening / closing state of the garbage grab bucket 11. If it is determined that the garbage... If garbage is being grabbed or scattered in a garbage area, it indicates that the area is a target area for lime spraying. At this time, when the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, the lime powder spraying unit can be controlled to spray lime powder onto the garbage in the target area, thereby spraying lime onto the surface of the garbage in the target area and forming a lime protective layer to prevent the breeding of mosquitoes and flies. When the garbage area is not being grabbed or scattered, it means that the garbage area does not need to be sprayed with lime. At this time, no related actions can be performed, thereby maintaining the lime protective layer on the surface of the garbage and also saving lime.
[0068] In the above embodiment, the device includes a lime powder conveying unit, a lime powder spraying unit, and a spraying control system; wherein, the output end of the lime powder conveying unit is connected to the input end of the lime powder spraying unit, and the output end of the lime powder spraying unit is connected to the spraying control system; thus, the lime powder conveying unit can pneumatically convey lime powder to the lime powder spraying unit, and the lime powder spraying unit is evenly distributed on the perimeter wall 7 around the garbage storage pit, and can precisely spray garbage in different areas of the garbage storage pit. This utilizes the principle of lime killing pests (the chemical reaction produced by the reaction of lime and water, biological...). The bactericidal effect of calcium hydroxide and the physical and chemical properties of lime itself can achieve insecticidal effect and save lime. Specifically, after the spray control system of this application collects the position information of the garbage crane 10 and the opening and closing status of the garbage grab bucket 11, it can determine the target area in the garbage storage pit that needs to be sprayed with lime based on the position information and opening and closing status. When the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, the system controls the lime powder spraying unit to spray lime powder onto the garbage in the target area, so as to efficiently and accurately eliminate mosquitoes and flies and maintain the environmental protection image of the waste incineration power plant.
[0069] In one embodiment, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the lime powder conveying unit provided in the embodiment of this application; the lime powder conveying unit includes a lime storage bin 1, a lime rotary feed valve 2, a lime weighing feed bin 3 and a lime screw feed valve 4 connected in sequence in a first direction, and a Roots blower 6 and a Venturi injection pipe 5 connected in sequence in a second direction perpendicular to the first direction, the bottom of the lime screw feed valve 4 and the top of the Venturi injection pipe 5 are connected through it.
[0070] The lime rotary feeder 2 replenishes the lime weighing feeder 3 according to the real-time weight of the lime weighing feeder 3.
[0071] The lime screw feeder 4 is used to control the feeding speed of the lime weighing feeder 3.
[0072] The Roots blower 6 is used to input high-pressure air into the Venturi injection pipe 5, so that after the Venturi injection pipe 5 is located at the bottom area of the lime spiral feed valve 4, a negative pressure zone is formed, and the lime powder in the negative pressure zone is sucked into the Venturi injection pipe 5 and transported to the input end of the lime powder injection unit along with the high-pressure air.
[0073] In this embodiment, as Figure 2As shown, the lime powder conveying unit of this application may include a feeding assembly and a conveying assembly. The feeding assembly may include a lime storage silo 1, a lime rotary feed valve 2, a lime weighing feed silo 3, and a lime screw feed valve 4, connected sequentially in a first direction. The lime storage silo 1 stores lime powder. The lime rotary feed valve 2 periodically replenishes the lime weighing feed silo 3. When the weight of the lime weighing feed silo 3 falls below a lower limit, the lime rotary feed valve 2 automatically starts replenishing the powder. When the weight of the lime weighing feed silo 3 reaches a set upper limit, the lime rotary feed valve 2 automatically stops replenishing the powder. Furthermore, the lime screw feed valve 4 below the lime weighing feed silo 3 also has a frequency conversion control function, which can control the lime feeding speed according to the weight of the lime powder in the lime weighing feed silo 3 and the lime spraying time.
[0074] Furthermore, the conveying assembly of this application may include a Roots blower 6 and a Venturi injection pipe 5 connected sequentially in a second direction perpendicular to the first direction. The bottom of the lime screw feeder 4 is connected through the top of the Venturi injection pipe 5. In this way, when the Roots blower 6 is working, it can input high-pressure air into the Venturi injection pipe 5, so that after the Venturi injection pipe 5 is located in the bottom area of the lime screw feeder 4, a negative pressure zone is formed. The lime powder in the negative pressure zone is sucked into the Venturi injection pipe 5 and conveyed to the input end of the lime powder injection unit along with the high-pressure air, so as to continuously supply lime powder to the lime powder injection unit.
[0075] In one embodiment, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the lime powder spraying unit provided in the embodiment of this application; the lime powder spraying unit includes a lime spraying pipe network 8 installed on the perimeter wall 7 around the garbage storage pit, and electric butterfly valves 9 evenly distributed on the lime spraying pipe network 8.
[0076] Each electric butterfly valve 9 has a spray nozzle corresponding to the garbage in a specific area within the garbage storage pit.
[0077] In this embodiment, as Figure 3 As shown, the lime powder injection unit of this application may include a lime injection pipeline network 8 installed on the perimeter wall 7 around the garbage storage pit, and electric butterfly valves 9 evenly distributed on the lime injection pipeline network 8. In this way, after the lime powder conveying unit delivers lime powder to the lime injection pipeline network 8, the electric butterfly valves 9 at the corresponding positions can be activated by the injection control system to achieve the effect of precise injection.
[0078] In one embodiment, the spraying control system includes a data acquisition unit, a central processing unit, a lime pipeline electric butterfly valve 9 controller, and a memory. The lime powder spraying unit includes electric butterfly valves 9 evenly distributed on the perimeter wall 7 around the garbage storage pit. The lime pipeline electric butterfly valve 9 controller is electrically connected to each electric butterfly valve 9.
[0079] The data acquisition unit is used to collect and send the location information of the garbage crane 10, the opening and closing status of the garbage grab bucket 11, and the opening and closing status of each electric butterfly valve 9 to the central processing unit.
[0080] The memory is used to store the position information of each electric butterfly valve 9 after being encoded according to the coordinate system of the waste storage plane.
[0081] The central processing unit is used to select the target electric butterfly valve 9 that is closest to the garbage grab bucket 11 based on the position information of the garbage crane 10 and the position information of each electric butterfly valve 9. When it is detected that the opening and closing state of the garbage grab bucket 11 meets the preset action, and it is determined that the lime powder conveying unit is in the start state and the target electric butterfly valve 9 is in the closed state, the central processing unit sends an instruction to open the electric butterfly valve 9 to the lime pipeline electric butterfly valve 9 controller.
[0082] The controller of the lime pipeline electric butterfly valve 9 is used to open the target electric butterfly valve 9 at the corresponding position according to the instruction to open the electric butterfly valve 9, so as to spray lime powder onto the garbage in the corresponding area through the target electric butterfly valve 9.
[0083] In this embodiment, the spraying control system may include a data acquisition unit, a central processing unit, a lime pipeline electric butterfly valve 9 controller, and a memory. The lime powder spraying unit may include electric butterfly valves 9 evenly distributed on the perimeter wall 7 around the garbage storage pit. The lime pipeline electric butterfly valve 9 controller is electrically connected to each electric butterfly valve 9. In this way, the central processing unit can determine whether lime needs to be sprayed on the garbage in the garbage storage pit based on the data acquired by the data acquisition unit and the data stored in the memory. When lime needs to be sprayed, the lime pipeline electric butterfly valve 9 controller can control the electric butterfly valve 9 at the corresponding position to spray lime.
[0084] Specifically, the data acquisition unit of this application can collect and send the position information of the garbage crane 10, the opening and closing status of the garbage grab bucket 11, and the opening and closing status of each electric butterfly valve 9 to the central processing unit. The memory stores the position information of each electric butterfly valve 9 after encoding according to the garbage storage plane coordinate system. For example, this application can establish a garbage storage plane coordinate system and encode the position information of each electric butterfly valve 9 according to the garbage storage plane coordinate system, namely {(x1,y1), (x2,y2)………..(xn,yn)}, and then store the position information of each electric butterfly valve 9 in the memory. Thus, the central processing unit receives the garbage crane position information sent by the data acquisition unit. After obtaining the location information of the garbage crane 10 and the opening / closing status of the garbage grab bucket 11, the target electric butterfly valve 9 closest to the garbage grab bucket 11 can be selected based on the location information of the garbage crane 10 and the location information of each electric butterfly valve 9. When the opening / closing status of the garbage grab bucket 11 is detected to meet the preset action, and it is determined that the lime powder conveying unit is in the start state and the target electric butterfly valve 9 is in the closed state, an instruction to open the electric butterfly valve 9 is sent to the lime network electric butterfly valve 9 controller. In this way, the lime network electric butterfly valve 9 controller can open the target electric butterfly valve 9 at the corresponding location according to the instruction to open the electric butterfly valve 9, so as to spray lime powder onto the garbage in the corresponding area through the target electric butterfly valve 9.
[0085] Indicatively, such as Figure 4 As shown, Figure 4 This is a structural schematic diagram of the side of a waste storage pit provided in an embodiment of this application; through Figure 4As can be seen, this application evenly installs multiple electric butterfly valves 9 on the perimeter wall 7 around the garbage storage pit. A data acquisition unit collects real-time information on the position of the garbage crane 10 above the garbage storage pit and the opening / closing status of the garbage grab bucket 11. The central processing unit compares the received position information of the garbage crane 10 with the position information of the electric butterfly valves 9 stored in the memory, selecting the electric butterfly valve 9 closest to the garbage grab bucket as the target electric butterfly valve 9. Then, the central processing unit can determine whether the opening / closing status of the garbage grab bucket 11 conforms to a preset action. If the garbage grab bucket 11 performs an "open-close" or "close-open" action, it indicates that the garbage area corresponding to the target electric butterfly valve 9 in the garbage storage pit is grabbing or scattering garbage, and the lime protective layer on the garbage surface is damaged. At this time, the central processing unit can determine whether the lime powder conveying unit is in the activated state and whether the target electric butterfly valve 9 is in the closed state. Under normal circumstances, the lime powder conveying unit is in the activated state to keep the pressure in the lime injection pipeline network 8 working, and the electric butterfly valve 9 is in the closed state. When lime needs to be injected, the electric butterfly valve 9 is opened to inject lime into the garbage storage pit. Therefore, when the central processing unit determines that the lime powder conveying unit is in the start state and the target electric butterfly valve 9 is in the closed state, it can send an instruction to open the electric butterfly valve 9 to the lime pipeline electric butterfly valve 9 controller. After receiving the instruction to open the electric butterfly valve 9, the lime pipeline electric butterfly valve 9 controller executes the instruction to open the electric butterfly valve 9 and spray lime in the area to achieve the effect of lime killing insects.
[0086] In one embodiment, the controller for the lime network electric butterfly valve 9 can also be used for:
[0087] After the central processing unit stops sending the command to open the electric butterfly valve 9, the target electric butterfly valve 9 is closed after a delay.
[0088] In this embodiment, after receiving the command to open the electric butterfly valve 9, the controller of the lime pipeline electric butterfly valve 9 executes the command to spray lime onto the area. When the command disappears, it indicates that the lime spraying protection of the area has been completed. Therefore, the lime pipeline electric butterfly valve 9 controller of this application can close the target electric butterfly valve 9 after the central processing unit stops sending the command to open the electric butterfly valve 9. The delay time can be set according to the actual situation, such as closing the target electric butterfly valve 9 after a delay of 10 seconds, or closing the target electric butterfly valve 9 after a delay of 15 seconds, etc., and is not limited here.
[0089] In one embodiment, the central processing unit can also be used for:
[0090] When the opening and closing state of the garbage grab 11 is detected to be inconsistent with the preset action, no instruction is sent to the controller of the lime pipeline electric butterfly valve 9.
[0091] In this embodiment, the spray control system continuously monitors the position information of the garbage crane 10 and the opening and closing status of the garbage grab bucket 11. When the garbage grab bucket 11 grabs garbage, it controls the electric butterfly valve 9 to spray lime on the garbage in the area to eliminate mosquitoes and flies on the garbage surface. When the operator leaves for a long time and does not grab garbage, the spray control system will not spray lime on the garbage storage pit when it detects that the garbage grab bucket 11 is not opening or closing, thereby saving lime.
[0092] In one embodiment, such as Figure 5 As shown, Figure 5 This application provides a schematic flowchart of a spray control method for a mosquito and fly control device in a garbage storage pit, as described in an embodiment of this application. This application also provides a spray control method for a mosquito and fly control device in a garbage storage pit, applied to the spray control system in any of the above embodiments. The method may include:
[0093] S110: Collects the location information of the garbage crane 10 and the opening and closing status of the garbage grab bucket 11.
[0094] S120: Determine the target area within the waste storage pit that needs to be sprayed with lime based on location information and opening / closing status.
[0095] S130: When the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, control the lime powder spraying unit to spray lime powder onto the garbage in the target area.
[0096] In this embodiment, the output end of the lime powder conveying unit can be connected to the input end of the lime powder spraying unit, and the output end of the lime powder spraying unit can be connected to the spraying control system. In this way, the spraying control system can collect the position information of the garbage crane 10 and the opening and closing state of the garbage grab bucket 11. After determining the target area in the garbage storage pit that needs to be sprayed with lime based on the collected position information of the garbage crane 10 and the opening and closing state of the garbage grab bucket 11, it is determined whether the working state of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions. If the preset conditions are met, the spraying control system can directly control the lime powder spraying unit to spray lime powder onto the garbage in the target area. If the preset conditions are not met, the working state of the lime powder conveying unit and the lime powder spraying unit can be adjusted to meet the preset conditions before controlling the lime powder spraying unit to spray lime powder onto the garbage in the target area.
[0097] Specifically, since the location information of the garbage crane 10 and the opening / closing state of the garbage grab bucket 11 change continuously as the garbage cleaning work progresses, this application can first obtain the location information of the garbage crane 10 and the opening / closing state of the garbage grab bucket 11 when determining whether there is a target area in the garbage storage pit that needs to be sprayed with lime. This allows for the determination of the lime powder spraying unit at the corresponding position on the perimeter wall 7 of the garbage storage pit and the targeted garbage area using the location information of the garbage crane 10, and also allows for the determination of whether garbage is being grabbed or scattered in that garbage area using the opening / closing state of the garbage grab bucket 11. If it is determined that the garbage... If garbage is being grabbed or scattered in a garbage area, it indicates that the area is a target area for lime spraying. At this time, when the working status of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, the lime powder spraying unit can be controlled to spray lime powder onto the garbage in the target area, thereby spraying lime onto the surface of the garbage in the target area and forming a lime protective layer to prevent the breeding of mosquitoes and flies. When the garbage area is not being grabbed or scattered, it means that the garbage area does not need to be sprayed with lime. At this time, no related actions can be performed, thereby maintaining the lime protective layer on the surface of the garbage and also saving lime.
[0098] The preset conditions here can be that the lime powder conveying unit is in the start state and the target electric butterfly valve 9 is in the closed state. When these two states are reached, the lime powder spraying unit can be directly controlled to spray lime powder onto the garbage in the target area.
[0099] In one embodiment, the lime powder spraying unit includes electrically operated butterfly valves 9 evenly distributed on the perimeter wall 7 surrounding the waste storage pit.
[0100] S120, determining the target area within the waste storage pit that needs to be sprayed with lime based on the location information and the opening / closing state, may include:
[0101] S121: Obtain the pre-stored position information of each electric butterfly valve 9 after being encoded according to the plane coordinate system of the waste storage area.
[0102] S122: Select the target electric butterfly valve 9 that is closest to the garbage grab bucket 11 based on the position information of the garbage crane 10 and the position information of each electric butterfly valve 9.
[0103] S123: Determine whether the opening and closing state of the garbage grab 11 conforms to the preset action; if it does, execute S124; if it does not, execute S125.
[0104] S124: The area corresponding to the spray port of the target electric butterfly valve 9 is designated as the target area in the garbage storage pit where lime needs to be sprayed.
[0105] S125: Determine that lime does not need to be sprayed in the current waste storage pit.
[0106] In this embodiment, as Figure 6 As shown, Figure 6 This is a flowchart illustrating the process of determining the target area within a garbage storage pit that needs to be sprayed with lime, as provided in this application embodiment. The lime powder spraying unit of this application may include electric butterfly valves 9 evenly distributed on the perimeter walls 7 surrounding the garbage storage pit. After obtaining the position information of the garbage crane 10 and the opening / closing state of the garbage grab bucket 11, the spraying control system can obtain the pre-stored position information of each electric butterfly valve 9 encoded according to the garbage pit plane coordinate system. In this way, the target electric butterfly valve 9 closest to the garbage grab bucket 11 and the corresponding garbage area can be selected based on the position information of the garbage crane 10 and the position information of each electric butterfly valve 9. The opening / closing state of the garbage grab bucket 11 can also be used to determine whether the garbage area is being grabbed or scattered. If the opening and closing state of the grab bucket 11 conforms to the preset action, it indicates that the garbage area is grabbing or throwing garbage. This garbage area can be identified as the target area for lime spraying. At this time, when the working state of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, the lime powder spraying unit can be controlled to spray lime powder onto the garbage in the target area, thereby spraying lime onto the surface of the garbage in the target area and forming a lime protective layer to prevent mosquitoes and flies from breeding. If the opening and closing state of the garbage grab bucket 11 does not conform to the preset action, it indicates that the garbage area is not grabbing or throwing garbage, and the garbage area does not need to be sprayed with lime. At this time, no related action can be performed, thereby maintaining the lime protective layer on the surface of the garbage and also saving lime.
[0107] In one embodiment, S130, when it is determined that the operating states of the lime powder conveying unit and the lime powder spraying unit meet preset conditions, controlling the lime powder spraying unit to spray lime powder onto the garbage in the target area may include:
[0108] S131: Determine whether the lime powder conveying unit is in the start-up state.
[0109] S132: If it is in the start state, determine whether the target electric butterfly valve 9 is in the closed state.
[0110] S133: If it is in the closed state, open the target electric butterfly valve 9 and spray lime powder onto the garbage in the target area through the target electric butterfly valve 9.
[0111] S134: If not in the closed state, continue to spray lime powder onto the garbage in the target area through the target electric butterfly valve 9.
[0112] S135: If not in the start state, after starting the lime powder conveying unit, return to the process of determining whether the target electric butterfly valve 9 is in the closed state and its subsequent steps.
[0113] In this embodiment, when determining whether the working state of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, it can first be determined whether the lime powder conveying unit is in the start state. If it is in the start state, it can then be determined whether the target electric butterfly valve 9 is in the closed state. If it is in the closed state, the target electric butterfly valve 9 is opened, and lime powder is sprayed onto the garbage in the target area through the target electric butterfly valve 9. If it is not in the closed state, it indicates that the target solenoid valve is in the working state, and at this time, lime powder can continue to be sprayed onto the garbage in the target area through the target electric butterfly valve 9. If it is not in the start state, after starting the lime powder conveying unit, it is necessary to continue to determine whether the target electric butterfly valve 9 is in the closed state, and to perform subsequent actions according to the opening and closing state of the target electric butterfly valve 9, so that when it is determined that the working state of the lime powder conveying unit and the lime powder spraying unit meets the preset conditions, the lime powder spraying unit can be controlled to spray lime powder onto the garbage in the target area.
[0114] In one embodiment, the method may further include:
[0115] If it is determined that the opening and closing state of the garbage grab 11 does not conform to the preset action, and the target electric butterfly valve 9 is still in the open state, the target electric butterfly valve 9 is closed after a delay.
[0116] In this embodiment, the spray control system continuously monitors the position information of the garbage crane 10 and the opening and closing status of the garbage grab bucket 11 during operation. When the garbage grab bucket 11 grabs garbage, it controls the electric butterfly valve 9 to spray lime on the garbage in that area to eliminate mosquitoes and flies on the garbage surface. When the operator leaves for a long time and does not grab garbage, the spray control system will not spray lime on the garbage storage pit if it detects that the opening and closing status of the garbage grab bucket 11 does not meet the preset action, i.e., there is no opening and closing action, thereby saving lime.
