Description

Technical Field

[0001] This invention relates to the field of waste collection technology, and in particular to a pure electric waste collection vehicle with a sewage collection structure. Background Technology

[0002] Garbage collection and transportation refers to the collection and transport of garbage. It includes the collection and transportation of various types of garbage, such as community household waste, construction waste, and slag, as well as garbage collection from companies, enterprises, factories, shopping malls, hotels, construction sites, schools, entertainment venues, training centers, and other locations. Garbage collection vehicles are required for this process.

[0003] Pure electric garbage trucks are new energy sanitation vehicles powered by lithium iron phosphate batteries with zero exhaust emissions. They have green license plates, are low-noise and enclosed, and are the mainstream models for collecting and transporting domestic waste in urban communities, streets and parks. They are divided into four categories: micro, light, medium and heavy, covering all scenarios of garbage collection and transportation needs.

[0004] For example, a garbage collection vehicle, as disclosed in Chinese Patent Publication No. CN221776715U, includes a truck body for loading garbage and a discharge port for garbage entry and exit; a collection component with two connection states: unfolded and retracted. When unfolded, the collection component is laid below the discharge port; a drive component connected to the collection component and rotatably configured to retract or release the collection component; the collection component includes a connecting component fixedly disposed at the free end of the collection component and used to guide the collection component; a waterproof layer is attached to the collection component; and the collection component is a roll-up curtain. By setting up the collection component, it is laid on the ground below the discharge port, and spilled garbage or leachate falls directly onto the collection component. The collection component collects the spilled garbage or leachate, preventing direct environmental pollution from garbage or leachate, reducing the labor intensity of sanitation workers, and improving the efficiency of garbage transfer.

[0005] In existing technical references, a collection component with a concave, arc-shaped waterproof tarpaulin can be used to naturally form a water collection area to collect sewage. However, when collecting sewage, especially when dealing with garbage with a lot of leachate, the sewage needs to be treated and emptied before it is full. Otherwise, leachate will overflow, causing secondary pollution, increasing the auxiliary time for garbage collection, and making it inconvenient for continuous garbage recycling. Summary of the Invention

[0006] To solve the above technical problems, the present invention is implemented through the following technical solution:

[0007] A pure electric garbage collection vehicle with a sewage collection structure includes:

[0008] An electric vehicle and a garbage storage compartment mounted on top of the electric vehicle. A garbage lifting mechanism is installed on the side of the surface of the electric vehicle, and an opening and closing mechanism is installed at the rear of the garbage storage compartment. The opening and closing mechanism is used to seal the garbage inside the garbage storage compartment. A sewage collection mechanism is installed between the bottom of the electric vehicle and the bottom of the garbage storage compartment. The sewage collection mechanism is used to control sewage in an orderly manner so as to collect it continuously.

[0009] The wastewater collection mechanism includes a wastewater collection bucket and a water collection trough. The wastewater collection bucket is detachably and fixedly installed on the side of the bottom of the electric vehicle via a right-angled plate. The wastewater collection buckets are arranged in an orderly manner on the bottom of the electric vehicle. The water collection trough is detachably and fixedly installed on the side of the bottom of the garbage storage compartment. A conical cap is detachably and fixedly installed on the top of the wastewater collection bucket. A hose connector is connected to the bottom of the water collection trough. A multi-channel connecting pipe is detachably and fixedly installed on the top of the conical cap. The hose connector, the multi-channel connecting pipe, and the conical cap are connected to form a wastewater collection channel. An auxiliary component is installed inside the garbage storage compartment near the water collection trough. The bottom of the wastewater collection bucket is connected to... The system includes a drain pipe, and a guide rod is fixedly connected to the middle of the sewage collection tank. A conical floating end cap is slidably connected to the surface of the guide rod. The conical floating end cap uses buoyancy to control the sewage entering the sewage collection tank. The sewage in the garbage storage compartment is collected through the water collection tank at the bottom of the garbage storage compartment. A complete and sealed sewage collection channel is formed by the hose joint, multi-channel connecting pipe, conical cap and sewage collection tank at the bottom of the electric vehicle. It can accurately collect various types of sewage such as leachate, rainwater and melted sewage in the garbage storage compartment. This changes the problem of traditional garbage trucks not having a dedicated sewage collection structure and sewage dripping onto the road along the gaps in the compartment, effectively avoiding road pollution, odor diffusion and road slippery safety hazards.

[0010] Furthermore, the water collection tank is sealed to the garbage storage compartment, the multi-channel connecting pipe is installed directly above the conical cap, there are two multi-channel connecting pipes, and the two multi-channel connecting pipes are symmetrically installed along the central axis of the electric vehicle, and the inner diameter of the conical floating end block gradually increases from top to bottom.

[0011] After the sewage enters the sewage collection tank, the conical floating end block comes into contact with the sewage and is subjected to upward buoyancy by the buoyancy linkage structure between the guide rod inside the sewage collection tank and the conical floating end block, which can realize adaptive water level control.

[0012] When the sewage in the sewage collection tank accumulates to a certain height, the conical floating end cap is buoyed and slides upward along the guide rod, automatically sealing the lower port of the conical cap, cutting off the sewage inlet channel of the multi-channel connecting pipe, and preventing sewage overflow and leakage. The sewage collection tank is equipped with a drainage pipe at the bottom, which can realize centralized sewage discharge at fixed points. The sewage discharge is convenient and there is no secondary pollution, which greatly improves the environmental protection standardization of garbage collection and transportation operations and meets the high-standard operation requirements of urban sanitation.

[0013] Furthermore, the auxiliary components are used to create a fence-like barrier for the garbage in the garbage storage compartment and to filter out any residue in the garbage;

[0014] The auxiliary components include a baffle plate, a protective shell, and a filter screen. The baffle plate is installed inside the garbage storage compartment and near the water collection tank. A straight hole is formed on the surface of the baffle plate, which, together with the baffle plate, forms a fence to intercept garbage inside the garbage storage compartment. A connecting pin is fixedly connected to the bottom of the outer side of the baffle plate. The connecting pin is rotatably installed between the inner wall of the garbage storage compartment and a bushing. The connecting pin passes through the garbage storage compartment and extends to its outside. The protective shell is fixedly installed on the surface of the garbage storage compartment, and the connecting pin extends into the interior of the protective shell. The filter screen is fixedly installed on the top of the water collection tank. A spiral spring is fixedly connected between the outer circular surface of the connecting pin and the inner wall of the protective shell.

[0015] Furthermore, the baffle plate is installed at an angle, the straight holes are evenly distributed on the surface of the baffle plate, and the baffle plate is installed above the filter screen.

[0016] Furthermore, the connecting pin passes through the center of the worm gear spring, and there are two connecting pins, which are symmetrically installed along the baffle plate.

[0017] Furthermore, the garbage lifting mechanism is used to lift and tip over garbage bins containing garbage. The garbage lifting mechanism includes a hydraulic cylinder and a lift. The hydraulic cylinder is fixedly installed on the side of the garbage storage compartment surface. The lift is fixedly installed on the telescopic end of the hydraulic cylinder. A connecting slider is installed at the output end of the lift. A support plate is hinged to the bottom of the connecting slider. A support tooth is fixedly connected to the side of the support plate surface near the lift. A roller is rolled on the top of the support tooth, and the outer surface of the roller is in contact with the surface of the lift. A telescopic device is fixedly connected to the top of the support plate near the garbage storage compartment. The top of the telescopic device is fixedly equipped with a hook tooth, and a bent guide rail is fixedly connected to the top side of the lifting platform. By extending the telescopic ends of two symmetrical hydraulic cylinders, a downward pushing force can be applied to the two symmetrical lifting platforms, which can make the lifting platforms move downward and adjust the overall height of the lifting platforms so that the tray mounted on the lifting platform through the connecting slider can contact the ground, which helps to move the garbage can containing garbage onto the tray. By retracting the telescopic ends of the hydraulic cylinders, an upward pulling force can be applied to the lifting platforms, which can make the lifting platforms move upward. The bottom end of the lifting platform and the tray are lifted off the ground, which facilitates the movement of electric vehicles and avoids obstruction.

[0018] Furthermore, both the hydraulic cylinders and the lifting platform are installed vertically. There are two hydraulic cylinders, and the two hydraulic cylinders are symmetrically installed along the support plate. There are also two lifting platforms, and the two lifting platforms are symmetrically installed along the support plate.

[0019] Utilizing a symmetrical drive structure with dual lifts, and connected by a slider, the pallet can be lowered to provide a stable vertical driving force for garbage lifting operations. The force is evenly distributed during operation, preventing deviation and swaying. The pallet, combined with support teeth and rollers sliding along the guide rail, effectively improves the stability of the lifting operation, preventing the garbage bin from tilting and falling during lifting. Simultaneously, the telescopic mechanism moves the hook teeth downwards to secure the garbage bin. As the pallet lifts the garbage bin, the lift raises it, and with the support teeth, the rollers enter the curved guide rail. Guided by the curved guide rail, the entire process of lifting, tilting, and unloading the garbage bin is precisely completed. This highly automated and convenient operation significantly reduces manual intervention and the workload of sanitation workers. It also effectively avoids garbage spillage and sewage splashing during manual unloading, improving the cleanliness and safety of the operation.

[0020] Furthermore, the telescopic device is installed vertically, the hook teeth are hooked on the side of the top of the trash can, and the hook teeth and the telescopic device form a structure to fix the trash can, and the bent guide rail is installed directly above the roller.

[0021] Furthermore, the opening and closing mechanism includes a cylinder and an opening and closing plate. The cylinder is rotatably mounted at the top of the rear of the garbage storage compartment. The top of the opening and closing plate is hinged to the rear of the garbage storage compartment. The telescopic end of the cylinder is hinged to the surface of the opening and closing plate. A sealing block is fixedly connected to the surface of the opening and closing plate. The sealing block is embedded in the garbage outlet at the rear of the garbage storage compartment. A wedge-shaped actuating block is fixedly connected to the surface of the sealing block. In the initial state, the telescopic end of the cylinder extends... Pressing pressure can be applied to the opening and closing plate, which is sealed at the rear of the garbage storage compartment. The inclined surface of the wedge-shaped jacking block fits against the top of the baffle, thus supporting the baffle and preventing it from tipping over. The inclined baffle with a straight hole forms a fence interception structure, which can effectively block large debris and prevent large debris from accumulating above the water collection tank and causing pipe blockage. The filter screen below can accurately filter small impurities such as fine mud and food residue, achieving fine graded filtration of sewage.

[0022] Furthermore, the cylinders are installed at an angle, and there are two cylinders, which are symmetrically installed along the central axis of the opening and closing plate. The sealing block is made of rubber. When the electric vehicle transports garbage from the full garbage storage compartment, the sealing block can be embedded in the garbage outlet at the rear of the garbage storage compartment to seal the garbage outlet and prevent garbage from falling out and sewage from seeping out. When the electric vehicle transports the garbage from the garbage storage compartment to the designated location, the cylinders are activated. The contraction of the cylinder's telescopic end applies a pulling force to the opening and closing plate. This causes the opening and closing plate to rotate counterclockwise and open, separating from the baffle plate via the wedge-shaped jacking block. The supporting force on the baffle plate disappears, and under the pressure of the garbage, the baffle plate rotates clockwise to a horizontal position, covering the top of the filter screen and facilitating the discharge of garbage from the garbage storage compartment. At the same time, the baffle plate drives the connecting pin to rotate, causing the worm gear spring to be subjected to torque force and undergo elastic deformation. When the garbage in the garbage storage compartment is discharged, the pressure on the baffle plate disappears, and under the elastic force of the worm gear spring itself, the baffle plate rotates in the opposite direction to reset, and the baffle plate is in an inclined state again.

[0023] The core components of the sewage collection system, such as the sewage collection tank, water collection trough, conical cap, and multi-channel connecting pipe, can all be disassembled and installed individually. This makes it easy for staff to regularly disassemble and clean the accumulated sludge and residue inside, while also facilitating the inspection and replacement of parts, thus significantly reducing the difficulty and cost of equipment operation and maintenance.

[0024] The equipment is rationally laid out and compactly structured. Its pure electric drive mode is green and energy-saving. Combined with a stable mechanical transmission and elastic reset structure, the equipment experiences less wear and tear and has a low failure rate, effectively extending its overall service life. Compared with traditional garbage trucks, it offers higher overall cost-effectiveness and is suitable for routine and large-scale urban sanitation and garbage collection operations.

[0025] The beneficial effects of the technical solution provided by this invention include:

[0026] 1. By collecting wastewater in the garbage storage compartment through the water collection tank at the bottom of the garbage storage compartment, and forming a complete and sealed wastewater collection channel with the hose joint, multi-channel connecting pipe, conical cap and wastewater collection bucket at the bottom of the electric vehicle, it can accurately collect various types of wastewater such as leachate, rainwater and melting wastewater in the garbage storage compartment. It changes the problem of traditional garbage collection vehicles not having a dedicated wastewater collection structure and wastewater dripping onto the road along the gaps in the compartment, effectively avoiding road pollution, odor diffusion and road slippery safety hazards.

[0027] 2. After the sewage enters the sewage collection tank, relying on the buoyancy linkage structure between the guide rod inside the sewage collection tank and the conical floating end cap, the conical floating end cap contacts the sewage and is subjected to upward buoyancy, which can realize adaptive water level control. When the sewage in the sewage collection tank accumulates to a certain height, the conical floating end cap slides upward along the guide rod under the buoyancy, automatically sealing the lower port of the conical cap, cutting off the sewage inlet channel of the multi-channel connecting pipe, and preventing sewage overflow and leakage problems.

[0028] 3. In the initial state, the extension of the cylinder extension end can apply pressure to the opening and closing plate. The sealing end of the opening and closing plate is at the rear of the garbage storage compartment, and the inclined surface of the wedge-shaped push block is in contact with the top of the baffle plate, which can support the baffle plate and prevent it from tipping over. The inclined baffle plate with a straight hole forms a fence interception structure, which can effectively block large-volume debris and prevent large debris from accumulating above the water collection tank and causing pipeline blockage. The filter screen below can accurately filter small impurities such as fine mud and food residue, realizing fine graded filtration of sewage.

[0029] Fourth, by embedding a sealing block into the garbage outlet at the rear of the garbage storage compartment, the garbage outlet at the rear of the garbage storage compartment can be sealed to prevent garbage from falling and sewage from seeping out. When the electric vehicle transports the garbage in the garbage storage compartment to the designated location, the contraction of the cylinder extension end can apply a pulling force to the opening and closing plate, causing the opening and closing plate to rotate counterclockwise and open. Through the wedge-shaped jacking block separating from the baffle plate, the supporting force on the baffle plate disappears, and under the pressure of the garbage, the baffle plate rotates clockwise to present a horizontal state covering the top of the filter screen, which also facilitates the discharge of garbage in the garbage storage compartment.

[0030] 5. By extending the telescopic ends of two symmetrical hydraulic cylinders, a downward pushing force can be applied to the two symmetrical lifting platforms, causing the lifting platforms to move downwards and adjusting the overall height of the lifting platforms. This allows the pallet mounted on the lifting platform via the connecting slider to contact the ground, facilitating the movement of garbage bins onto the pallet. Conversely, by retracting the telescopic ends of the hydraulic cylinders, an upward pulling force can be applied to the lifting platforms, causing the entire lifting platform to move upwards. The bottom of the lifting platform and the pallet are lifted off the ground, allowing electric vehicles to avoid obstruction during operation.

[0031] VI. Utilizing a symmetrical drive structure with dual lifting platforms, and with the connection of the slider, the pallet can be lowered to provide a stable vertical driving force for garbage lifting operations. The force is evenly distributed during operation, preventing deviation and shaking. The pallet, combined with the support teeth and rollers sliding against the guide rail, effectively improves the stability of the lifting operation and prevents the garbage bin from tilting and falling during lifting. At the same time, the hook teeth are moved down by the telescopic device to fix the garbage bin. As the pallet lifts the garbage bin, the lifting platform raises it. With the support of the support teeth, the rollers enter the interior of the bent guide rail. Under the limiting and guiding effect of the bent guide rail, the entire process of lifting, tilting, and unloading the garbage bin is accurately completed. Attached Figure Description

[0042] Example 1, see Figures 1-5 A technical solution is provided:

[0043] A pure electric garbage collection vehicle with a sewage collection structure includes:

[0044] Electric vehicle 1, and garbage storage compartment 2 installed on top of electric vehicle 1. Garbage lifting mechanism 3 is installed on the side of the surface of electric vehicle 1. Opening and closing mechanism 4 is installed at the rear of garbage storage compartment 2. Opening and closing mechanism 4 is used to seal the garbage in garbage storage compartment 2. Sewage collection mechanism 5 is installed between the bottom of electric vehicle 1 and the bottom of garbage storage compartment 2. Sewage collection mechanism 5 is used to orderly control sewage so as to continuously collect it.

[0045] The sewage collection mechanism 5 includes a sewage collection bucket 51 and a water collection tank 52. The sewage collection bucket 51 is detachably and fixedly installed on the side of the bottom of the electric vehicle 1 via a right-angled plate. The sewage collection buckets 51 are arranged in an orderly manner on the bottom of the electric vehicle 1. The water collection tank 52 is detachably and fixedly installed on the side of the bottom of the garbage storage compartment 2. A conical cap 53 is detachably and fixedly installed on the top of the sewage collection bucket 51. A hose connector 54 is connected to the bottom of the water collection tank 52. A multi-channel connector is detachably and fixedly installed on the top of the conical cap 53. The multi-channel connecting pipe 55, hose connector 54, and conical cap 53 are connected to form a sewage collection channel. An auxiliary component 56 is installed inside the garbage storage compartment 2 near the water collection tank 52. A drain pipe 57 is connected to the bottom of the sewage collection tank 51. A guide rod 58 is fixedly connected to the middle of the inside of the sewage collection tank 51. A conical floating end block 59 is slidably connected to the surface of the guide rod 58. The conical floating end block 59 uses buoyancy to control the sewage entering the sewage collection tank 51.

[0046] Wastewater from garbage is collected in the garbage storage compartment 2 by the water collection tank 52 at the bottom of the garbage storage compartment 2. A complete and sealed wastewater collection channel is formed by the hose connector 54, multi-channel connecting pipe 55, conical cap 53 and wastewater collection bucket 51 at the bottom of the electric vehicle 1. This can accurately collect various types of wastewater such as leachate, rainwater and melted wastewater in the garbage storage compartment 2. This changes the problem of traditional garbage trucks not having a dedicated wastewater collection structure and wastewater dripping onto the road along the gaps in the compartment. It effectively avoids road pollution, odor diffusion and road slippery safety hazards.

[0047] The water collection tank 52 is sealed to the garbage storage compartment 2. A multi-channel connecting pipe 55 is installed directly above the conical cap 53. There are two multi-channel connecting pipes 55, symmetrically installed along the central axis of the electric vehicle 1. The conical floating end cap 59 gradually increases in inner diameter from top to bottom. After sewage enters the sewage collection tank 51, relying on the buoyancy linkage structure between the guide rod 58 inside the sewage collection tank 51 and the conical floating end cap 59, the conical floating end cap 59 contacts the sewage and is subjected to upward pressure. The buoyancy allows for adaptive water level control. When the sewage in the sewage collection tank 51 accumulates to a certain height, the conical floating end cap 59 slides upward along the guide rod 58 under the buoyancy, automatically sealing the lower port of the conical cap 53, cutting off the sewage inlet channel of the multi-channel connecting pipe 55, and preventing sewage overflow and leakage. The bottom of the sewage collection tank 51 is equipped with a drainage pipe 57, which can realize centralized sewage discharge at fixed points. The sewage discharge is convenient and there is no secondary pollution, which greatly improves the environmental standardization of garbage collection operations and meets the high-standard operation requirements of urban sanitation.

[0048] The auxiliary component 56 is used to create a fence-like barrier for the garbage in the garbage storage compartment 2 and to filter out any residue in the garbage.

[0049] The auxiliary component 56 includes a baffle plate 561, a protective shell 562, and a filter screen 563. The baffle plate 561 is installed inside the garbage storage compartment 2 and near the water collection tank 52. A straight hole 564 is opened on the surface of the baffle plate 561. The straight hole 564 and the baffle plate 561 form a fence to intercept the garbage in the garbage storage compartment 2. A connecting pin 565 is fixedly connected to the bottom of the outer side of the baffle plate 561. The connecting pin 565 is rotatably installed between the inner wall of the garbage storage compartment 2 through a bushing. The connecting pin 565 passes through the garbage storage compartment 2 and extends to its outside. The protective shell 562 is fixedly installed on the surface of the garbage storage compartment 2. The connecting pin 565 extends into the inside of the protective shell 562. The filter screen 563 is fixedly installed on the top of the water collection tank 52. A spiral spring 566 is fixedly connected between the outer circular surface of the connecting pin 565 and the inner wall of the protective shell 562.

[0050] The baffle plate 561 is installed at an angle, and the straight holes 564 are evenly distributed on the surface of the baffle plate 561. The baffle plate 561 is installed above the filter screen 563.

[0051] The connecting pin 565 passes through the center of the worm gear spring 566. There are two connecting pins 565, and the two connecting pins 565 are symmetrically installed along the baffle 561.

[0052] Example 2, based on Example 1, see [link / reference] Figures 1 to 7 A technical solution is provided:

[0053] The garbage lifting mechanism 3 is used to lift and tip over garbage bins containing garbage. The garbage lifting mechanism 3 includes a hydraulic cylinder 31 and a lift 32. The hydraulic cylinder 31 is fixedly installed on the side of the surface of the garbage storage compartment 2. The lift 32 is fixedly installed on the telescopic end of the hydraulic cylinder 31. A connecting slider 33 is installed on the output end of the lift 32. A support plate 34 is hinged to the bottom of the connecting slider 33. A support tooth 35 is fixedly connected to the side of the surface of the support plate 34 near the lift 32. A roller 36 is rolled on the top of the support tooth 35. The outer surface of the roller 36 is in contact with the surface of the lift 32. A telescopic device 37 is fixedly connected to the top of the support plate 34 near the garbage storage compartment 2. A hook tooth 38 is fixedly installed on the top of the telescopic device 37. A bent guide rail 39 is fixedly connected to the side of the top of the surface of the lift 32.

[0054] By extending the telescopic ends of two symmetrical hydraulic cylinders 31, a downward pushing force can be applied to the two symmetrical lifting platforms 32, causing the lifting platforms 32 to move downward and adjusting the overall height of the lifting platforms 32 so that the pallet 34 installed on the lifting platform 32 via the connecting slider 33 can contact the ground. This facilitates the movement of the garbage bin containing garbage onto the pallet 34. By retracting the telescopic ends of the hydraulic cylinders 31, an upward pulling force can be applied to the lifting platform 32, causing the lifting platform 32 to move upward as a whole. The bottom end of the lifting platform 32 and the pallet 34 are lifted off the ground, making it easier for the electric vehicle 1 to avoid obstruction during operation.

[0055] Both hydraulic cylinders 31 and lifting platforms 32 are vertically installed. There are two hydraulic cylinders 31, which are symmetrically installed along the support plate 34. There are also two lifting platforms 32, which are symmetrically installed along the support plate 34. Utilizing the symmetrical layout of the double lifting platforms 32 and connected by the connecting slider 33, the support plate 34 can be lowered to provide a stable vertical driving force for garbage lifting operations. The force is evenly distributed during operation, and it is not easy to deviate or shake. The support plate is equipped with a structure in which the support teeth and rollers slide against the guide rail, which effectively improves the stability of the lifting operation and prevents the garbage bin from tilting and falling during the lifting process. At the same time, the hook teeth 38 are moved down by the telescopic device 37 to fix the garbage bin. As the support plate 34 lifts the garbage bin, the lifting platform 32 raises the garbage bin. With the support teeth 35, the rollers 36 enter the interior of the bent guide rail 39. Under the limiting and guiding effect of the bent guide rail 39, the entire process of lifting, flipping, and unloading the garbage bin is accurately completed.

[0056] The telescopic connector 37 is installed vertically, and the hook tooth 38 is hooked on the side of the top of the trash can. The hook tooth 38 and the telescopic connector 37 form a structure to fix the trash can. The bent guide rail 39 is installed directly above the roller 36.

[0057] Example 3, based on Examples 1 and 2, see below. Figures 1 to 9 A technical solution is provided:

[0058] The opening and closing mechanism 4 includes a cylinder 41 and an opening and closing plate 42. The cylinder 41 is rotatably mounted at the top of the rear of the garbage storage compartment 2. The top of the opening and closing plate 42 is hinged to the rear of the garbage storage compartment 2. The telescopic end of the cylinder 41 is hinged to the surface of the opening and closing plate 42. A sealing block 43 is fixedly connected to the surface of the opening and closing plate 42. The sealing block 43 is embedded in the garbage outlet at the rear of the garbage storage compartment 2. A wedge-shaped actuating block 44 is fixedly connected to the surface of the sealing block 43. In the initial state, the extension of the telescopic end of the cylinder 41 can apply pressure to the opening and closing plate 42. When pressure is applied, the opening and closing plate 42 is sealed at the rear of the garbage storage compartment 2, and the inclined surface of the wedge-shaped jacking block 44 is in contact with the top of the baffle plate 561, which can support the baffle plate 561 and prevent it from tipping over. The baffle plate 561 with the inclined shape and the straight hole 564 forms a fence interception structure, which can effectively block large debris and prevent large debris from accumulating above the water collection tank 52 and causing pipeline blockage. The filter screen 563 below can accurately filter small impurities such as fine mud and food residue, realizing fine graded filtration of sewage.

[0059] Two cylinders 41 are installed at an angle, symmetrically along the central axis of the opening and closing plate 42. The sealing block 43 is made of rubber. When the electric vehicle 1 transports garbage from the garbage storage compartment 2, the sealing block 43 can be embedded into the garbage outlet at the rear of the garbage storage compartment 2 to seal the outlet, preventing garbage from falling out and sewage from leaking out. When the electric vehicle 1 transports the garbage from the garbage storage compartment 2 to the designated location, the cylinders 41 are activated. The contraction of the telescopic end of the cylinder 41 applies a pulling force to the opening and closing plate 42, causing the plate to rotate counterclockwise. When the baffle plate 561 is separated by the wedge-shaped jacking block 44, the supporting force on the baffle plate 561 disappears, and under the pressure of the garbage, the baffle plate 561 rotates clockwise to a horizontal position, covering the top of the filter screen 563, which facilitates the discharge of garbage from the garbage storage compartment 2. At the same time, the baffle plate 561 drives the connecting pin 565 to rotate, so that the worm gear spring 566 is subjected to torque force and undergoes elastic deformation. When the garbage in the garbage storage compartment 2 is discharged, the pressure on the baffle plate 561 disappears, and under the elastic force of the worm gear spring 566 itself, the baffle plate 561 rotates in the opposite direction to reset, and the baffle plate 561 is in an inclined state again.

[0060] When in use, the extension of the cylinder 41 extension end first applies pressure to the opening and closing plate 42. The opening and closing plate 42 is sealed at the rear of the garbage storage compartment 2, and the inclined surface of the wedge-shaped push block 44 is in contact with the top of the baffle plate 561, which can support the baffle plate 561 and prevent the baffle plate 561 from tipping over.

[0061] Furthermore, by driving the electric vehicle 1 to pull the garbage storage compartment 2 to the garbage bin containing garbage, the extension of the telescopic ends of the two symmetrical hydraulic cylinders 31 can apply a downward pushing force to the two symmetrical elevators 32, thereby causing the elevators 32 to move downward and adjusting the overall height of the elevators 32.

[0062] Simultaneously, utilizing the symmetrical drive structure of the dual lifting platforms 32, and connected by the slider 33, the pallet 34 can be lowered, making contact with the ground, and the garbage bin can be moved onto the pallet 34. At the same time, the telescopic device 37 drives the hook teeth 38 to move down, which can fix the garbage bin. The lifting platform 32 provides a stable vertical driving force for the garbage lifting operation, ensuring even force distribution and preventing deviation or shaking. The structure of the pallet with support teeth and rollers sliding in close contact with the guide rail effectively improves the stability of the lifting operation and prevents the garbage bin from tilting and falling during the lifting process. As the pallet 34 lifts the garbage bin, the lifting platform 32 raises the garbage bin. With the support of the support teeth 35, the rollers 36 enter the interior of the bent guide rail 39. Under the limiting and guiding effect of the bent guide rail 39, the entire process of lifting, flipping, and unloading the garbage bin is accurately completed.

[0063] As the garbage is dumped into the garbage storage compartment 2, the inclined baffle 561 with a straight hole 564 forms a fence interception structure, which can effectively block large debris and prevent large debris from accumulating above the water collection tank 52 and causing pipe blockage. The filter screen 563 below can accurately filter small impurities such as fine mud and food residue, realizing fine graded filtration of sewage.

[0064] Furthermore, the wastewater in the waste storage compartment 2 is collected by the water collection tank 52 at the bottom of the waste storage compartment 2, and a complete closed wastewater collection channel is formed by the hose connector 54, the multi-channel connecting pipe 55, the conical cap 53 and the wastewater collection bucket 51 at the bottom of the electric vehicle 1, which can accurately collect various types of wastewater such as leachate, rainwater and melted wastewater in the waste storage compartment 2.

[0065] After the sewage enters the sewage collection tank 51, relying on the buoyancy linkage structure between the guide rod 58 inside the sewage collection tank 51 and the conical floating end block 59, the conical floating end block 59 contacts the sewage and is subjected to upward buoyancy, which can realize adaptive water level control. When the sewage in the sewage collection tank 51 accumulates to a certain height, the conical floating end block 59 slides upward along the guide rod 58 under the buoyancy, automatically sealing the lower port of the conical cap 53, cutting off the sewage inlet channel of the multi-channel connecting pipe 55, preventing sewage overflow and leakage. Furthermore, by using the sewage collection tank 51 evenly installed at the bottom of the electric vehicle 1, the sewage collection tank 51 can collect sewage one by one in an orderly manner.

[0066] When the garbage storage compartment 2 is full, the retraction of the extension end of the hydraulic cylinder 31 applies an upward pulling force to the elevator 32, causing the elevator 32 to move upward as a whole. The bottom end of the elevator 32 and the support plate 34 are lifted off the ground, and the garbage storage compartment 2 is then pulled to the designated garbage disposal location by the electric vehicle 1. The cylinder 41 is then activated, and the retraction of the extension end of the cylinder 41 applies a pulling force to the opening and closing plate 42, causing the opening and closing plate 42 to rotate counterclockwise and open. The wedge-shaped jacking block 44 separates from the baffle plate 561. When the supporting force disappears and under the pressure of the garbage, the baffle 561 rotates clockwise to a horizontal position, covering the top of the filter screen 563, which facilitates the discharge of garbage from the garbage storage compartment 2. At the same time, the baffle 561 drives the connecting pin 565 to rotate, causing the worm gear spring 566 to be subjected to torque and undergo elastic deformation. When the garbage in the garbage storage compartment 2 is discharged, the pressure on the baffle 561 disappears, and under the elastic force of the worm gear spring 566 itself, the baffle 561 rotates in the opposite direction to reset, and the baffle 561 is in an inclined state again.

[0067] Open the valve on the drain pipe 57 to drain the sewage from the sewage collection tank 51 and rinse the inside of the garbage storage compartment 2.

[0068] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
