Description

Technical Field

[0001] This invention belongs to the field of silo unloading technology, specifically relating to a fixed silo unloading and loading control method with vehicle model adaptive function. Background Technology

[0002] Boiler slag is a solid waste generated during the coal combustion process. It is the final product formed by the physicochemical changes of minerals in coal under high temperature. After boiler slag is generated in the boiler, it is swept out and sent to a fixed silo, and then transported to other locations by transport vehicles and other transportation equipment.

[0003] In existing technology, since the location of the silo is fixed, the transport vehicle needs to be driven below the discharge port according to the location of the silo discharge port. During the discharge process, the transport personnel need to judge the height of the boiler slag in the transport vehicle based on their personal judgment and control the movement of the transport vehicle. However, since the storage capacity of the transport vehicle varies depending on the model, the above process cannot detect the boiler slag in the transport vehicle. Relying solely on the personal judgment of the transport personnel results in too much or too little material in the transport vehicle. Furthermore, a lot of dust is often generated during the discharge process, affecting the environmental safety of the discharge area. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fixed hopper unloading and loading control method with material unloading detection, dust handling and vehicle model adaptation function.

[0005] The technical solution of the present invention is as follows:

[0006] A method for controlling the unloading and loading of a fixed hopper with vehicle model adaptive function includes the following steps;

[0007] S1. Establish a vehicle information database and associate vehicle information, license plate information, boiler slag height, number of feedings and displacement distance. The control equipment can obtain the corresponding vehicle information and license plate information from the database.

[0008] S2. The transport vehicle drives into the parking garage and is positioned below the unloading port. The license plate recognition device identifies the vehicle information and sends it back to the control equipment.

[0009] S3. Obtain vehicle information based on license plate information. Retrieve the corresponding vehicle information from the database. After the position detection equipment detects the position information of the transport vehicle, the control equipment determines the unloading point and the longitudinal displacement range of the unloading based on the transport vehicle information. Then, control the displacement equipment to work based on the position information of the transport vehicle.

[0010] S4. The displacement device controls the material discharge port to move to the material discharge point. The control device controls the material discharge port to open and removes dust through the dust removal device. During the material discharge process, the laser rangefinder detects the height information of the boiler slag inside the vehicle. The control device controls the upward movement speed of the material discharge port based on the boiler slag height change data.

[0011] S5. When the boiler slag height reaches the boiler slag height corresponding to the vehicle information in the database, the control device closes the discharge port and reminds the transport vehicle to move. When the transport vehicle moves, the position detection device detects the position of the transport vehicle. When the displacement distance is reached, the control device controls the reminder device to prompt the driver to stop. Then the control device continues to discharge according to step S4 until all discharges are completed. Then the discharge port moves up to reset, and the transport vehicle can drive out of the parking garage.

[0012] Furthermore, the control device establishes a spatial coordinate system based on the location and size of the parking garage, and confirms the unloading point based on the position of the position detection device in the spatial coordinate system and the position of the transport vehicle detected by the position detection device.

[0013] Furthermore, the dust removal equipment includes at least one end plate fixed to the discharge port, a dust removal component rotatably connected to the end plate, a servo motor for driving the dust removal component to rotate, a water pump fixed to the parking garage, a water tank connected to the water pump, and an air extraction device connected to the dust removal component. The servo motor is fixed to the end plate, the water pump is connected to the dust removal component, and the water tank is fixed to the parking garage.

[0014] Furthermore, the dust removal assembly includes a hollow cylinder connected to a servo motor, a water storage shell fixed inside the cylinder, a perforated plate fixed to the top of the water storage shell, a filter assembly disposed above the perforated plate, and a guide pipe opened on the inner wall of the water storage shell. A channel is vertically opened in the middle of the water storage shell, the upper end of the channel is closed, and the channel is connected to the upper part of the guide pipe.

[0015] The cylinder has openings at both the top and bottom ends, and the opening at the top end is rotatably sealed to a sealing shell. The sealing shell is connected to an air extraction device so that the air extraction device is connected to the opening on the top side of the cylinder.

[0016] The cylinder has an inlet located between the filter assembly and the perforated plate, and the sealing shell has a connection port that communicates with the water pump.

[0017] The filter assembly knocks on the perforated plate and dumps dust as the cylinder rotates. The filter assembly vibrates itself when dumping dust, and the water in the water storage tank is gradually discharged from the opening at the top of the cylinder as the cylinder rotates.

[0018] Furthermore, the filter assembly includes four pressure regulating assemblies arranged horizontally and rotatably connected in the cylinder, a filter screen disposed on the pressure regulating assemblies, contact seals disposed at the left and right ends of the filter screen, a connecting barrel connected below the pressure regulating assemblies, a drive assembly A, and a drive assembly B. Adjacent contact seals, contact seals and cylinder, and filter screen and cylinder are all in contact and sealed.

[0019] The cylinder has driving cavities at both ends of its axial direction. Driving component A and driving component B are located in the two driving cavities respectively. Both driving component A and driving component B can mesh with the end plate. The pressure adjustment component is connected to driving component A to drive the pressure adjustment component to adjust the pressure and rotate.

[0020] The connecting barrel is connected to the pressure regulating assembly. Inside the connecting barrel, there is a transmission assembly that moves along the axial direction of the connecting barrel with the pressure. The driving assembly B has a groove for the displacement of the transmission assembly. The driving assembly B has displacement holes located at both ends of the groove. The displacement holes move with the displacement of the transmission assembly and are driven by the driving assembly B. The connecting barrel rotates with the rotation of the transmission assembly. Multiple striking balls are arranged on the outer circumference of the connecting barrel.

[0021] Furthermore, the pressure regulating assembly includes a fixed cylinder rotatably connected to the inner wall of the cylinder, a threaded shaft connected to the drive assembly A, a threaded cylinder connected to the threaded shaft, a pressure regulating piston fixed on the threaded cylinder, and spring telescopic rods fixed at both ends of the fixed cylinder. The threaded shaft, the threaded cylinder, and the pressure regulating piston are all located inside the fixed cylinder, and the threaded shaft is rotatably and sealingly connected to the fixed cylinder.

[0022] The spring telescopic rod near one end of the drive assembly A connects the connecting barrel and the fixed barrel;

[0023] The axial side of the pressure regulating piston is polygonal.

[0024] Furthermore, the drive assembly A includes a drive gear meshing with the end plate, a worm gear mechanism that drives the drive gear, and four transmission gears that drive the worm gear mechanism. The four transmission gears are respectively connected to four threaded shafts, and the four transmission gears are divided into left and right groups. The transmission gears in the same group rotate in the same direction. The four filter screens are divided into left and right groups, and the cross-sections of the two contact seals in the same group that are in contact with each other are inclined planes with the same inclination angle. When the filter screens in the same group rotate in the same direction, the inclined planes of the two contact seals in the same group that are in contact with each other move away from each other or move closer to each other.

[0025] Furthermore, the drive assembly B includes a drive gear meshing with the end plate, a worm gear mechanism that drives the drive gear, a fixed plate fixed in the drive cavity, four tooth grooves on the fixed plate, four main gears that drive the worm gear mechanism, and a driven gear that drives the main gears. The main gears and driven gears are all located in the tooth grooves. The main gears, tooth grooves, and driven gears are all provided with arc-shaped sliding grooves. The three sliding grooves form a sliding groove, and the two ends of the sliding groove are located at the axis of the main gear and the driven gear, respectively. The diameter of the sliding groove gradually decreases from that of the main gear, so that the spring telescopic rod can be extended and retracted when the connecting barrel is displaced.

[0026] The groove is provided with a guide ridge, the thickness of which gradually increases from both ends to the middle. The transmission component passes through the guide ridge. The two ends of the displacement hole groove are provided with tapered teeth at the bottom of the displacement hole on the main gear and semi-circular toothed rings at the top of the displacement hole on the driven gear.

[0027] The end plate has an arc-shaped meshing groove, and the upper and lower ends of the arc-shaped meshing groove are respectively provided with cleaning teeth that mesh with the drive gear of the drive component B. The middle of the arc-shaped meshing groove is provided with a rotating tooth that meshes with the drive gear of the drive component A.

[0028] Furthermore, the transmission assembly includes two mirror-arranged bevel gears, a connecting column coaxially fixed on the two bevel gears, and a displacement piston. The end of the connecting barrel near the bevel gear has a displacement cavity, which connects to the connecting barrel. The displacement piston is sealed and inserted into the displacement cavity. The guide convex strip is located between the two bevel gears. The two bevel gears can respectively mesh with the conical teeth and the tooth ring. The connecting barrel is fixed with a sealing disc that contacts the side wall of the cylindrical plane.

[0029] Furthermore, the discharge port is connected to the storage tank via an elastic tube. The displacement device includes an electric slide rail fixed to the parking garage, a movable frame fixed to the electric slide rail, a drive device fixed to the movable frame, a buffer rod fixed to the movable frame, a roller body disposed on the buffer rod, and a connecting belt connected to the drive device.

Detailed Implementation

[0046] 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.

[0047] like Figure 1-11 As shown, a fixed hopper unloading and loading control method with vehicle model adaptive function includes the following steps;

[0048] S1. Establish a vehicle information database and associate vehicle information, license plate information, boiler slag height, number of feedings and displacement distance. The control device 14 can obtain the corresponding vehicle information and license plate information from the database.

[0049] S2. The transport vehicle 15 drives into the parking room 11 and is located below the unloading port 1. The license plate recognition device 12 recognizes the vehicle information and feeds it back to the control device 14.

[0050] S3. Obtain vehicle information based on license plate information. Obtain the corresponding vehicle information from the database. Then, after the position detection device 13 detects the position information of the transport vehicle 15, the control device 14 determines the unloading point and the longitudinal displacement range of the unloading based on the information of the transport vehicle 15. Then, control the displacement device to work based on the position information of the transport vehicle 15.

[0051] S4. The displacement device controls the discharge port 1 to move to the discharge point. The control device 14 controls the discharge port 1 to open and removes dust through the dust removal device. During the discharge process, the laser rangefinder 6 detects the height information of the boiler slag inside the vehicle. The control device 14 controls the upward movement speed of the discharge port 1 based on the boiler slag height change data.

[0052] S5. When the boiler slag height reaches the boiler slag height corresponding to the vehicle information in the database, the control device 1 closes the discharge port 1 and reminds the transport vehicle 15 to move. When the transport vehicle 15 moves, the position detection device 13 detects the position of the transport vehicle 15. When the displacement distance is reached, the control device 14 controls the reminder device 16 to prompt the driver to stop. Then the control device 14 discharges material according to step S4 until all the discharges are completed. Then the discharge port 1 moves up and resets. At this time, the transport vehicle 15 can drive out of the parking garage 11.

[0053] In this embodiment, the control device 14 establishes a spatial coordinate system based on the location and size of the parking garage 11, and confirms the unloading point based on the position of the position detection device 13 in the spatial coordinate system and the position of the transport vehicle 15 detected by the position detection device 13.

[0054] The control device 14 is an industrial computer, PLC control circuit or other control device. The position detection device 13 is a laser rangefinder 6 and a vision detector. The position of the transport vehicle 15 is confirmed based on the distance information detected by the laser rangefinder 6 and the position information captured by the vision detector. The reminder device specifically adopts a speaker or a display screen or a combination thereof to prompt the driver to control the movement of the transport vehicle 15 through sound or image.

[0055] In this embodiment, the dust removal equipment includes at least one end plate 2 fixed on the discharge port 1, a dust removal component 3 rotatably connected to the end plate 2, a servo motor 4 for driving the dust removal component 3 to rotate, a water pump 10 fixed on the parking garage 11, a water tank 9 connected to the water pump 10, and an air extraction device 7 connected to the dust removal component 3. The servo motor 4 is fixed on the end plate 2, the water pump 10 is connected to the dust removal component 3, and the water tank 9 is fixed on the parking garage 11.

[0056] When in use, the water pump 10 fills the dust removal component 3 with water. After filling, it is turned off. The air extraction device 7 extracts air, and the dust enters the dust removal component 3 for dust removal. After the transport vehicle 15 is filled, the servo motor 4 drives the dust removal device to rotate, and the dust removal device pours out the sewage. Then the servo motor 4 drives the dust removal device to rotate and reset. After that, water can be added again according to the above process.

[0057] The air extraction device 7 can be any device that can extract air, such as an exhaust fan, air pump, or fan.

[0058] In this embodiment, the dust removal assembly 3 includes a hollow cylinder 38 connected to a servo motor 4, a water storage shell 36 fixed inside the cylinder 38, a perforated plate 35 fixed on the top of the water storage shell 36, a filter assembly disposed above the perforated plate 35, and a guide pipe 37 opened on the inner wall of the water storage shell 36. A channel 31 is vertically opened in the middle of the water storage shell 36, the upper end of the channel 31 is closed, and the channel 31 is connected to the upper part of the guide pipe 37.

[0059] The cylinder 38 has openings at both the top and bottom ends, and the upper opening is in rotatable sealing contact with a sealing shell 34. The sealing shell 34 is connected to the air extraction device 7, so that the air extraction device 7 is connected to the upper opening of the cylinder 38.

[0060] The cylinder 38 has an inlet 32 ​​located between the filter assembly and the perforated plate 35, and the sealing shell 34 has a connection port 33 that communicates with the water pump 10.

[0061] As the cylinder 38 rotates, the filter assembly knocks on the perforated plate 35 and dumps dust. The filter assembly vibrates itself when dumping dust, and the water in the water storage shell 36 is gradually discharged from the opening above the cylinder 38 as the cylinder 38 rotates.

[0062] In use, the water pump 10 discharges water into the cylinder 38 through the connection port 33 and the inlet 32. The water in the circumference flows into the water storage tank 36 through the perforated plate 35. When the water in the water storage tank 36 is below the connection between the guide pipe 37 and the channel 31, the water addition stops. Then, the air extraction device 7 extracts air from below the cylinder 38 through the channel 31, the guide pipe 37, the water in the water storage tank 36, and the filter assembly. The air undergoes a first dust removal when passing through the water and a second dust removal when passing through the filter assembly to ensure the dust removal effect. After the dust removal is completed, the servo motor 4 drives the cylinder 38 to rotate counterclockwise 180°. When rotating from 0° to 60°, the filter assembly knocks on the perforated plate 35. When rotating from 60° to 120°, the filter assembly gradually opens, and the water in the water storage tank 36 is discharged. When rotating from 120° to 180°, the filter assembly itself vibrates to remove dirt. After that, it is reset and water is added again.

[0063] The air extraction device 7 and the water pump 10 are both connected to the sealing shell 34 and the connection port 33 via a retractable flexible hose.

[0064] In this embodiment, the filter assembly includes four pressure adjustment assemblies 301 arranged horizontally and rotatably connected in the cylinder 38, a filter screen 314 disposed on the pressure adjustment assembly 301, contact seals 315 sealed and fixed at the left and right ends of the filter screen 314, a connecting barrel 302 connected below the pressure adjustment assembly 301, a drive assembly A and a drive assembly B, and adjacent contact seals 315, contact seals 315 and cylinder 38, and filter screen 314 and cylinder 38 are all in contact and sealed.

[0065] The cylinder 38 has drive cavities 39 at both ends of the axial direction. Drive assembly A and drive assembly B are located in the two drive cavities 39 respectively. Both drive assembly A and drive assembly B can mesh with end plate 2. Pressure adjustment assembly 301 is connected to drive assembly A to drive pressure adjustment assembly 301 to adjust pressure and rotate.

[0066] The connecting barrel 302 is connected to the pressure regulating assembly 301. A transmission assembly is provided inside the connecting barrel 302, which moves along the axial direction of the connecting barrel 302 with the pressure. The driving assembly B has a slide groove for the displacement of the transmission assembly. The driving assembly B has displacement holes 3072 located at both ends of the slide groove. The displacement holes 3072 move with the displacement of the transmission assembly and are driven by the driving assembly B. The connecting barrel 302 rotates with the rotation of the transmission assembly. Multiple striking balls 3023 are provided on the outer circumference of the connecting barrel 302. In the initial state, the striking balls 3023 are in contact with the orifice plate 35 and not with the filter assembly. When the cylinder 38 rotates to 120°-180°, the striking balls 3023 are in contact with the orifice plate 35 and are in contact with the filter assembly.

[0067] During operation, as cylinder 38 rotates counterclockwise, drive assembly B drives the connecting barrel 302 to rotate via the transmission assembly when the rotation is between 0° and 60°. The connecting barrel 302 drives the striking ball 3023 to strike the orifice plate 35, causing dust on the orifice plate 35 to detach. When cylinder 38 rotates to 60-120°, drive assembly A operates while drive assembly B ceases operation. At this time, drive assembly A drives pressure adjustment assembly 301 to adjust the pressure, causing the transmission assembly to displace axially along the connecting barrel 302, thus discontinuing the transmission between the two components. Subsequently, as the pressure of pressure adjustment assembly 301 increases... As the drive assembly increases, it gradually enables the filter screen 314 and the connecting barrel 302 to rotate. During the rotation, the distance between the connecting barrel 302 and the filter screen 314 decreases. When the filter screen 314 can no longer rotate, the transmission assembly continues to drive the drive assembly B. When the cylinder 38 rotates to 120°-180°, the drive assembly drives the connecting barrel 302 to rotate and drives the striking ball 3023 to strike the filter screen 314 to remove dust from the filter screen 314. Similarly, when the cylinder 38 rotates to reset, the transmission is carried out according to the above process, and the filter screen 314 and the connecting barrel 302 are reset.

[0068] In this embodiment, the pressure regulating assembly 301 includes a fixed cylinder 3011 rotatably connected to the inner wall of the cylinder 38, a threaded shaft 3012 connected to the drive assembly A, a threaded cylinder 3014 connected to the threaded shaft 3012, a pressure regulating piston 3015 fixed on the threaded cylinder 3014, and spring telescopic rods 3013 fixed at both ends of the fixed cylinder 3011. The threaded shaft 3012, the threaded cylinder 3014, and the pressure regulating piston 3015 are all located inside the fixed cylinder 3011, and a column is fixed to one end of the threaded shaft 3012 and the column is rotatably and sealingly connected to the fixed cylinder 3011.

[0069] The spring telescopic rod 3013 near one end of the drive assembly A connects the connecting barrel 302 and the fixed barrel 3011;

[0070] The axial side surface of the pressure regulating piston 3015 is polygonal;

[0071] The spring telescopic rod 3013 includes a cylinder and a rod. A spring connected to the rod is installed inside the cylinder. The rod is in sealed contact with the cylinder. The rod has an annular groove and a vertical hole. The sliding hole connects the annular groove and the cylinder. The connecting barrel 302 is rotatably and sealedly connected to the annular groove and communicates with the annular groove.

[0072] During use, the threaded rod rotates with the rotation of the drive assembly A. During the rotation, the pressure of the fixed cylinder 3011 gradually increases or decreases and injects or extracts air into the connecting barrel 302 to control the position of the transmission assembly. As the pressure inside the fixed cylinder 3011 changes, the friction between the threaded shaft 3012 and the threaded cylinder 3014 also gradually increases until the threaded shaft 3012 can drive the threaded cylinder 3014 to rotate. The threaded cylinder 3014 drives the fixed cylinder 3011 to rotate through the pressure regulating piston 3015. The fixed cylinder 3011 drives the corresponding connecting barrel 302 to rotate through the spring telescopic rod 3013, thereby ensuring the rotation of the connecting barrel 302.

[0073] In this embodiment, the drive assembly A includes a drive gear 306 meshing with the end plate 2, a worm gear mechanism 30 that drives the drive gear 306, and four transmission gears 311 that drive the worm gear mechanism 30 through a gear set. The four transmission gears 311 are respectively connected to four threaded shafts 3012, and the four transmission gears 311 are divided into left and right groups. The transmission gears 311 in the same group rotate in the same direction. The four filter screens 314 are divided into left and right groups, and the cross-sections of the two contact seals 315 in the same group that are in contact with each other are inclined surfaces with the same inclination angle. When the filter screens 314 in the same group rotate in the same direction, the inclined surfaces of the two contact seals 315 in the same group that are in contact with each other move away from each other or move closer to each other.

[0074] In use, the drive gear 306 meshes with the end plate 2 when the cylinder 38 rotates 60°-120°. Then, the worm gear mechanism 30 works and drives the transmission gear 311 to rotate through the gear set. The transmission gear 311 drives the threaded shaft 3012 to rotate, ensuring the drive.

[0075] In this embodiment, the drive assembly B includes a drive gear 306 meshing with the end plate 2, a worm gear mechanism 30 that drives the drive gear 306, a fixed plate 308 fixed in the drive cavity 39, four toothed grooves 309 on the fixed plate 308, four main gears 307 that drive the worm gear mechanism 30, and a driven gear 310 that drives the main gears 307. The main gears 307 and the driven gears 310 are all located in the toothed grooves 309. The main gears 307, the toothed grooves 309, and the driven gears 310 are all provided with arc-shaped sliding grooves. The three sliding grooves form a sliding groove, and the two ends of the sliding groove are located at the axis of the main gears 307 and the driven gears 310, respectively. The diameter of the sliding groove gradually decreases from the main gears 307, so that the spring telescopic rod 3013 can be extended and retracted when the connecting barrel 302 is displaced.

[0076] A guide rib 3071 is provided in the groove, and the transmission component passes through the guide rib 3071. At both ends of the groove of the displacement hole 3072, the bottom of the displacement hole 3072 on the main gear 307 is provided with a bevel tooth, and the top of the displacement hole 3072 on the slave gear 310 is provided with a semi-circular toothed ring 3101. The guide rib 3071 gradually shifts away from the cylinder 38 along the axial direction of the cylinder 38 from the main gear 307. That is, when the transmission component disengages from the displacement hole 3072 of the main gear 307 and moves along the guide rib 3071, the gap between the transmission component and the toothed ring 3101 gradually increases as the transmission component moves along the guide rib 3071, so that the transmission component can smoothly enter the displacement hole 3072 and continue to move. Both ends of the guide rib 3071 are provided with spring pieces so that the transmission component can enter the guide rib 3071 along the spring pieces.

[0077] The end plate 2 has an arc-shaped meshing groove. The upper and lower ends of the arc-shaped meshing groove are respectively provided with cleaning teeth 201 that mesh with the drive gear 306 of the drive assembly B. The middle of the arc-shaped meshing groove is provided with rotating teeth 202 that mesh with the drive gear 306 of the drive assembly A.

[0078] At 0°-60°, the drive gear 306 of drive assembly B meshes with the cleaning gear 201 and drives the worm gear mechanism 30 to rotate. The worm gear mechanism 30 drives the main gear 307 and the driven gear 310 to rotate. The main gear 307 drives the connecting barrel 302 to rotate through the transmission assembly. When the rotation reaches 60°-120°, the drive gear 306 of drive assembly A meshes with the rotating gear 202 and drives the transmission. The pressure inside the connecting barrel 302 decreases, and the transmission assembly moves towards the connecting barrel 302 and contacts the guide protrusion 3071. At this time, the transmission assembly can disengage from the displacement hole 3072 of the main gear 307. Then the pressure inside the connecting barrel 302 continues to decrease until the threaded rod can drive the fixed cylinder 3011 to rotate. The transmission assembly moves along the guide protrusion 3071. When the transmission assembly moves along the guide protrusion 3071, the transmission assembly gradually moves away from the cylinder 38. When the transmission component is located at the spring plate, under low pressure, the transmission component is inserted into the displacement hole 3072 and meshes with the gear ring 3101. At this time, the driven gear 310 meshes with the transmission component. Then, when rotating to 120°-180°, the drive gear 306 of the drive component B meshes with the cleaning gear 201. The driven gear 310 drives the connecting barrel 302 to rotate through the transmission component. When the cylinder 38 is reset, the driven gear 310 continues to drive the transmission component and the connecting barrel 302 to rotate. When rotating to 60°-120°, the transmission component gradually disengages from the gear ring 3101 from the displacement hole 3072 of the gear 310 and enters the guide convex strip 3071 along the spring plate until it moves into the displacement hole 3072 of the main gear 307. Then, it is inserted into the conical tooth of the displacement hole 3072 at the spring plate, so that the main gear 307 can drive the transmission component to rotate, ensuring operation.

[0079] In this embodiment, the transmission assembly includes two mirror-arranged bevel gears 312, a connecting column 313 coaxially fixed on the two bevel gears 312, and a displacement piston 3022. A displacement cavity 3021 is opened at one end of the connecting barrel 302 near the bevel gears 312. The displacement cavity 3021 is connected to the connecting barrel 302. The displacement piston 3022 is sealed and inserted into the displacement cavity 3021. The guide rib 3071 and the spring are located between the two bevel gears 312. The two bevel gears 312 can respectively mesh with the conical teeth and the tooth ring 3101. A sealing disc 303 is fixed to the connecting barrel 302 and contacts the side wall of the cylindrical 38 plane.

[0080] During use, depending on the rotation angle of the cylinder 38, the bevel gear 312 meshes with the corresponding gear ring 3101 and bevel teeth, and can move along the guide ridge 3071 and the spring piece to ensure transmission.

[0081] In this embodiment, the discharge port 1 is connected to the storage tank 8 via an elastic tube. The displacement device includes an electric slide rail 22 fixed on the parking garage 11, a movable frame 21 fixed on the electric slide rail 22, a drive device 20 fixed on the movable frame 21, a buffer rod 17 fixed on the movable frame 21, a roller body 18 disposed on the buffer rod 17, and a connecting belt 19 connected to the drive device 20. The connecting belt 19 passes through the roller body 18 and is connected to the discharge port 1.

[0082] In use, the connecting belt 19 is retracted and extended by the drive device 20 to control the vertical displacement of the discharge port 1. The displacement of the discharge port 1 is driven by the electric slide rail 22, thereby realizing the adjustment of the position of the discharge port 1. The buffer rod 17 is used to buffer the downward and upward movement of the discharge port 1 to prevent the connecting belt 19 from breaking.

[0083] The drive device 20 is a drive motor, and the buffer rod 17 is a hydraulic rod.

[0084] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
