Description

Technical Field

[0001] This invention relates to the field of sanitation vehicle technology, specifically to a warning system for sanitation vehicles operating in violation of regulations. Background Technology

[0002] In the field of sanitation vehicle production and use technology, sanitation vehicles are generally equipped with a clean water tank and a sewage tank. When normal operation begins, the clean water tank is full and the sewage tank is empty. After cleaning is completed, the clean water tank is empty and the sewage tank is full. When working again, the driver needs to empty the sewage tank before adding water to the clean water tank.

[0003] Because the clean water tank and wastewater tank are large in size to meet operational requirements, the maximum gross vehicle weight is designed to only meet the requirements when the clean water tank is full. If the wastewater tank still contains water when the clean water tank is full, the vehicle will be overweight. Overweight vehicles will seriously damage road infrastructure. Overloading increases the load and inertia of the vehicle, and the braking distance will be longer. If the overloading is severe, the tires may blow out due to excessive deformation caused by excessive load, resulting in sudden swerving, brake failure, rollover and other accidents. In addition, overloading will also affect the vehicle's steering performance, making it easy to cause accidents due to loss of steering control.

[0004] However, in actual use of sanitation vehicles, some drivers, for convenience or due to negligence, add water to the clean water tank before the sewage tank is empty. This leads to overloading of the vehicle, which greatly affects the driving safety of the sanitation vehicle. At the same time, the clean water tank and sewage tank in most existing sanitation vehicles are arranged in a row. When the clean water tank is empty, the center of gravity of the sanitation vehicle will shift, reducing the stability of the sanitation vehicle. Furthermore, when existing sanitation vehicles pump sewage from the road, simple filtration increases the density of the sewage, increasing the load on the sanitation vehicle and wasting energy. Fine filtration often causes blockages, which is not conducive to the continuous and normal operation of sanitation work. Therefore, a warning system for illegal operation of sanitation vehicles is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a warning system for illegal operations of sanitation vehicles, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a warning system for illegal operation of sanitation vehicles, comprising a clean water tank located at the center of gravity of the sanitation vehicle, a wastewater tank located at the bottom of the clean water tank, a water spray nozzle located at the bottom of the clean water tank, a first liquid level sensor located inside the clean water tank, a first water spray pump fixedly connected inside the clean water tank at the water spray nozzle, a second liquid level sensor located inside the wastewater tank, a recycling mechanism located at the bottom of the wastewater tank, and a second water pump fixedly connected inside the wastewater tank at the recycling mechanism.

[0007] The recycling mechanism includes a bottom cavity block fixedly connected to the bottom of the sewage tank. A suction pipe is fixedly connected to the top of the bottom cavity block and is connected to a second water pump. A baffle filter plate is fixedly connected to one side of the bottom of the bottom cavity block. Several brooms are fixedly connected to the bottom of the baffle filter plate. Several suction tubes are fixedly connected to the bottom of the bottom cavity block away from the baffle filter plate. A through-slot is opened on the side wall of the bottom cavity block above the suction tubes. The end of the through-slot, away from the suction tubes, leads to the interior of the bottom cavity block.

[0008] Preferably, the clean water tank is provided with an inlet, and the wastewater tank is provided with an outlet. The inlet is located at the top of the clean water tank, and the outlet is located at the bottom of the wastewater tank. Both the inlet and the outlet are provided with a stop valve.

[0009] Preferably, the corner of the inclined filter plate away from the bottom cavity block is set as an arc corner, the sweeping bar is elastic, a plurality of the sweeping bars are arranged at equal distances, the bottom of the sweeping bar and the bottom of the water suction tube are located on the same horizontal plane, and the water suction tube is elastic.

[0010] Preferably, the bottom cavity block is provided with an anti-clogging mechanism to maintain the smooth flow of wastewater collection from the ground.

[0011] Preferably, the anti-clogging mechanism includes an outer sliding groove formed on the outside of the side wall of the bottom cavity block near the inclined filter plate, an inner sliding groove formed inside the side wall of the bottom cavity block near the inclined filter plate, a central sliding groove formed between the outer sliding groove and the inner sliding groove, a central connecting plate slidably connected to the central sliding groove, an inner filter plate fixedly connected to the side of the central connecting plate near the inside of the bottom cavity block, and an outer solid plate fixedly connected to the side of the central connecting plate near the inclined filter plate.

[0012] Preferably, a spring groove is provided at the lower part of the inner sliding groove, and a return spring is fixedly connected to the inner bottom surface of the spring groove. The end of the return spring away from the inner bottom surface of the spring groove is fixedly connected to the inner filter plate. The inner filter plate slides in the inner sliding groove, the outer solid plate slides in the outer sliding groove, and the end of the inner filter plate away from the inner sliding groove slides against the inner wall of the bottom cavity block.

[0013] Preferably, the diameter of the filter holes in the inner filter plate is smaller than that in the inclined filter plate, and the outer sliding groove, inner sliding groove and central sliding groove are all inclined, and the inner filter plate is inclined.

[0014] Preferably, the system also includes a microcontroller controller, an audible and visual alarm, a battery, and a drive controller. The microcontroller controller is electrically connected to the first liquid level sensor, the second liquid level sensor, the audible and visual alarm, and the drive controller. The battery powers the warning system.

[0015] Preferably, the microcontroller controller collects the liquid level L1 from the first liquid level sensor and the liquid level L2 from the second liquid level sensor. The microcontroller controller sets the load threshold of the sanitation vehicle and converts it into a liquid level range {X1, X2}. When the sum of L1 and L2 is greater than or equal to X1 and less than or equal to X2, the microcontroller controller controls the audible and visual alarm to start and limits the driving power of the sanitation vehicle to 50% of the normal value through the drive controller. When the sum of L1 and L2 is greater than X2, the microcontroller controller controls the audible and visual alarm to start and limits the driving power of the sanitation vehicle to 10% of the normal value through the drive controller.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up clean water tanks and sewage tanks, the clean water or sewage stored on the sanitation vehicle is located at the center of gravity of the sanitation vehicle, which greatly improves the stability of the sanitation vehicle, making the sanitation vehicle more stable and safer during operation. The structure is simple and efficient, and is suitable for widespread use.

[0018] 2. The recycling mechanism utilizes inclined filter plates to block large particles and sweeping strips to clean them, resulting in a lower density of wastewater collected by the system through the bottom cavity block. This significantly reduces the weight of the wastewater, saving energy for sanitation vehicles and facilitating the removal of sediment. It also reduces the filtration pressure on the internal filter plates. Furthermore, the elasticity of the suction tube allows it to penetrate into ground crevices to absorb water, increasing the water recovery rate and preventing water waste. This greatly enhances the system's environmental friendliness.

[0019] 3. The anti-clogging mechanism utilizes the guidance of the inclined filter plate, causing large particles filtered by the inclined filter plate to move upwards along the inclined filter plate and collide with the outer solid plate. This causes the outer solid plate to slide upwards in the outer sliding groove, and through the transmission of the central connecting plate, the inner filter plate slides up and down and vibrates in the inner sliding groove. This causes small particles clogging the filter holes of the inner filter plate to fall off due to the vibration of the inner filter plate, greatly improving the smoothness and stability of the system and significantly reducing the failure rate of the system. The structure is ingenious and efficient, making it suitable for widespread use.

[0020] 4. Through the configuration and collaboration of a microcontroller, an audible and visual alarm, and a drive controller, the system utilizes a first and a second liquid level sensor to measure the liquid levels in the clean water tank and the wastewater tank. This allows for the calculation of the total weight of the clean water and wastewater in the tanks. Combined with the sanitation vehicle's own load, the system activates the audible and visual alarm and limits the drive power of the sanitation vehicle when the total weight of the clean water tank and wastewater tank exceeds the limit. This provides a clear and unambiguous reminder to the driver, ensuring the sanitation vehicle remains in a safe driving state. This significantly improves the driving safety of the sanitation vehicle. The system is ingeniously designed and highly efficient, making it suitable for widespread use. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Reference Figure 1-9 As shown, the present invention provides a technical solution for a warning system for illegal operations of sanitation vehicles:

[0034] A warning system for violations of sanitation vehicle operation includes a clean water tank 1 located at the center of gravity of the sanitation vehicle, a wastewater tank 2 located at the bottom of the clean water tank 1, a water spray nozzle 103 located at the bottom of the clean water tank 1, a first liquid level sensor 101 located inside the clean water tank 1 for detecting the liquid level inside the clean water tank 1, a first water pump 102 fixedly connected inside the clean water tank 1 at the water spray nozzle 103 for spraying water from the clean water tank 1 onto the road surface to clean the road surface, a second liquid level sensor 201 located inside the wastewater tank 2 for detecting the liquid level inside the wastewater tank 2, a recycling mechanism located at the bottom of the wastewater tank 2, and a second water pump 202 fixedly connected inside the wastewater tank 2 at the recycling mechanism for sucking wastewater from the road surface into the wastewater tank 2.

[0035] The recycling mechanism includes a bottom cavity block 3 fixedly connected to the bottom of the sewage tank 2. A suction pipe 203 is fixedly connected to the top of the bottom cavity block 3 and is connected to the second water pump 202. A baffle filter plate 4 is fixedly connected to one side of the bottom of the bottom cavity block 3. Several sweeping bars 401 are fixedly connected to the bottom of the baffle filter plate 4. Several suction tubes 301 are fixedly connected to the bottom of the bottom cavity block 3 away from the baffle filter plate 4. A through groove pipe 307 is opened on the side wall of the bottom cavity block 3 above the suction tubes 301. The end of the through groove pipe 307 away from the suction tubes 301 leads to the interior of the bottom cavity block 3.

[0036] This invention, through the arrangement of a clean water tank 1 and a wastewater tank 2, ensures that both the clean water and wastewater stored on the sanitation vehicle are located at the vehicle's center of gravity. This avoids the conventional arrangement of tanks for storing clean water and wastewater on sanitation vehicles, which causes the center of gravity of the sanitation vehicle to shift as the clean water is used up, resulting in a significant decrease in the stability of the sanitation vehicle. This invention greatly improves the stability of the sanitation vehicle, making it more stable and safer during operation. The structure is simple, efficient, and suitable for widespread use.

[0037] In this warning system, during the use of the recycling mechanism, sewage mixed with road dirt passes through the inclined filter plate 4 and the sweeping bar 401. After being filtered once by the inclined filter plate 4 and the sweeping bar 401, the density of the sewage placed at the bottom of the bottom cavity block 3 is greatly reduced. At this time, due to the start of the second water pump 202, the second water pump 202 will draw the sewage placed below the bottom cavity block 3 through the suction pipe 203 and the bottom cavity block 3. At the same time, due to the elasticity of the suction pipe 301, as the sanitation vehicle moves, the bottom end of the suction pipe 301 will extend into the gaps in the ground. Under the action of negative pressure inside the bottom cavity block 3, the water in the gaps in the ground will be drawn into the bottom cavity block 3 and finally into the sewage tank 2.

[0038] The recycling mechanism utilizes the obstruction of large particles by the inclined filter plate 4 and the sweeping of large particles by the sweeping bar 401. This results in a lower density of the ground sewage recovered by the warning system through the bottom cavity block 3, greatly reducing the weight of the sewage. This not only saves energy consumed by sanitation vehicles due to their heavy loads but also facilitates the subsequent discharge of sediment in the sewage. It also reduces the filtration pressure on the inner filter plate 5. At the same time, the elasticity of the water suction tube 301 is utilized to extend into the crevices of the ground to absorb water, thereby increasing the proportion of water recovered by the warning system, avoiding water waste, and greatly improving the environmental friendliness of the warning system.

[0039] It should be noted that the clean water tank 1 is equipped with an inlet, and the sewage tank 2 is equipped with an outlet. The inlet is located at the top of the clean water tank 1, and the outlet is located at the bottom of the sewage tank 2. Both the inlet and outlet are equipped with stop valves. The corner of the inclined filter plate 4 away from the bottom cavity block 3 is set as an arc corner 402. It should be noted that the arc corner 402 is set to prevent the corner of the inclined filter plate 4 from breaking up impurities in the sewage on the road surface, thus preventing them from mixing into the bottom cavity block 3, increasing the density of the sewage, increasing the weight of the sewage, increasing the load on the sanitation vehicle, or further causing blockage at the inner filter plate 5, which would hinder the normal operation of the recycling mechanism. The sweeping strips 401 are elastic, and several sweeping strips 401 are arranged at equal distances. The bottom of the sweeping strips 401 and the bottom of the suction tube 301 are on the same horizontal plane. The suction tube 301 is elastic.

[0040] The bottom cavity block 3 is equipped with an anti-clogging mechanism to ensure the smooth flow of wastewater collected from the ground.

[0041] Example 2:

[0042] The anti-clogging mechanism includes an outer sliding groove 304 on the outside of the side wall of the bottom cavity block 3 near the inclined filter plate 4, an inner sliding groove 305 on the inside of the side wall of the bottom cavity block 3 near the inclined filter plate 4, a central sliding groove 306 between the outer sliding groove 304 and the inner sliding groove 305, a central connecting plate 501 slidably connected to the central sliding groove 306, an inner filter plate 5 fixedly connected to the side of the central connecting plate 501 near the inside of the bottom cavity block 3, and an outer solid plate 502 fixedly connected to the side of the central connecting plate 501 near the inclined filter plate 4.

[0043] The anti-clogging mechanism utilizes the guide of the inclined filter plate 4, causing large particles filtered by the inclined filter plate 4 to move upwards along the inclined filter plate 4 and collide with the outer solid plate 502. This causes the outer solid plate 502 to slide upwards within the outer sliding groove 304. Through the transmission of the central connecting plate 501, the inner filter plate 5 slides up and down and vibrates within the inner sliding groove 305. This causes small particles clogging the filter holes of the inner filter plate 5 to fall off due to the vibration of the inner filter plate 5. At the same time, the inclined setting of the inner filter plate 5 increases the filtration area and facilitates the falling of small particles from the inner filter plate 5. In summary, this greatly improves the smoothness and stability of the system, significantly reduces the failure rate of the system, and features a compact and efficient structure suitable for widespread use.

[0044] It should be noted that the lower part of the inner slide groove 305 is provided with a spring groove 302. A return spring 303 is fixedly connected to the inner bottom surface of the spring groove 302. The end of the return spring 303 away from the inner bottom surface of the spring groove 302 is fixedly connected to the inner filter plate 5. The inner filter plate 5 slides at the inner slide groove 305, and the outer solid plate 502 slides at the outer slide groove 304. The end of the inner filter plate 5 away from the inner slide groove 305 slides against the inner wall of the bottom cavity block 3. The diameter of the filter hole of the inner filter plate 5 is smaller than the diameter of the filter hole of the inclined filter plate 4. The outer slide groove 304, the inner slide groove 305 and the central slide groove 306 are all inclined. The inner filter plate 5 is inclined.

[0045] Example 3:

[0046] This warning system also includes a microcontroller, an audible and visual alarm, a battery, and a drive controller. The microcontroller is electrically connected to the first liquid level sensor 101, the second liquid level sensor 201, the audible and visual alarm, and the drive controller. The battery powers this warning system.

[0047] It should be noted that the microcontroller collects the liquid level L1 from the first liquid level sensor 101 and the liquid level L2 from the second liquid level sensor 201. Since the density of the sewage passing through the inner filter plate 5 is approximately the same, the weight of the sewage can be estimated by obtaining the liquid level of the sewage tank 2. This warning system sets the load threshold of the sanitation vehicle through the microcontroller and converts it into a liquid level range {X1, X2}. When the sum of L1 and L2 is greater than or equal to X1 and less than or equal to X2, the microcontroller controls the sound and light alarm to start and limits the driving power of the sanitation vehicle to 50% of the normal value through the drive controller. When the sum of L1 and L2 is greater than X2, the microcontroller controls the sound and light alarm to start and limits the driving power of the sanitation vehicle to 10% of the normal value through the drive controller.

[0048] By configuring and coordinating a microcontroller controller, an audible and visual alarm, and a drive controller, the system utilizes the first liquid level sensor 101 and the second liquid level sensor 201 to measure the liquid levels in the clean water tank 1 and the wastewater tank 2. This allows for the calculation of the total weight of the clean water and wastewater in the tanks. Combined with the sanitation vehicle's own load, the system activates the audible and visual alarm and limits the drive power of the sanitation vehicle when the total weight exceeds the limit. This provides a clear and unambiguous reminder to the driver, ensuring the sanitation vehicle remains in a safe driving state. This significantly improves the driving safety of the sanitation vehicle. The system is ingeniously designed, highly efficient, and suitable for widespread use.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
