Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of garbage trucks, in particular to a kitchen waste truck and a discharging system. BACKGROUND

[0002] At present, the kitchen waste truck adopts a rear flip cover discharging design. After the kitchen waste is collected from the collection point and transported to the kitchen waste treatment plant, it is put into the discharging room and undergoes several straight and reversing operations. The kitchen waste truck is parked in the kitchen waste storage pit position, then the isolation door of the storage pit is opened, the driver operates the discharging, the rear flip cover is opened, and the kitchen waste is directly flowed into the storage pit. At the same time, the front end of the vehicle-mounted hopper is lifted by the hydraulic system, so as to facilitate the kitchen waste at the front end of the hopper to flow into the storage pit through the rear end cover under the action of gravity.

[0003] The discharging system requires separate setting of the discharging room and the storage bin, and the kitchen waste truck needs to be reversed during discharging operation, so a sufficient turning radius needs to be designed, and the required operation and storage space is large. The operation of the driver during discharging operation is relatively complex, and the time required for discharging is relatively long. During the discharging process of the kitchen waste storage bin, the isolation door must be fully opened, and a large amount of odor is diffused into the discharging room during the discharging process. In addition, the kitchen waste truck needs to be reversed during discharging, and the kitchen waste that is splashed and leaked falls to the ground after being crushed by the tire, which can cause odor in the discharging room, so the working environment of the discharging room is poor. When the kitchen waste truck lifts the front end of the hopper, the rear of the kitchen waste truck will be heavy and the front will be light for a short time. If the operation is too fast or improper, the kitchen waste truck is easy to fall into the storage pit, causing an accident. Because the storage room and the discharging room have a large space, the odor concentration is high, so the amount of odor to be treated is large, and the investment and operation cost of the odor treatment facility are high. SUMMARY

[0004] The present application provides a kitchen waste truck and a discharging system to solve the problems of the kitchen waste truck with a rear flip cover discharging in the prior art, such as a large operation space, a risk of rear flip due to rear inclination during discharging, and a large amount of odor and high treatment cost.

[0006] According to the present invention, the side wall of the hopper connected to the unloading port is inclined at an angle of 3‰. And / or, the hopper is equipped with a shaftless screw to push the kitchen waste to the discharge port during unloading.

[0007] According to the present invention, a food waste truck also includes: a camera; The camera is mounted on the vehicle body and is positioned facing the unloading pipe.

[0008] In a second aspect, the present invention provides an unloading system, comprising: A food waste truck, wherein the food waste truck is as described in any of the preceding claims; The unloading room includes a first space located on the ground and a second space located underground.

[0010] According to the unloading system provided by the present invention, it further includes: an inlet position detection sensor, an outlet position detection sensor, and an unloading position detection sensor; Along the direction of travel of the food waste truck, the entrance position detection sensor is located on the rear side of the entrance isolation door, the exit position detection sensor is located on the front side of the exit isolation door, and the unloading position detection sensor is located on the front side of the storage bin; The inlet position detection sensor, the outlet position detection sensor, and the unloading position detection sensor are all electrically connected to the controller. Based on the position information of the kitchen waste truck fed back by the inlet position detection sensor, the outlet position detection sensor, and the unloading position detection sensor, the controller controls the opening and closing of the inlet isolation door and the outlet isolation door.

[0011] The unloading system provided by the present invention further includes: a crash bar; Along the direction of travel of the food waste truck, the anti-collision bar is flexibly and retractably positioned next to the unloading position detection sensor; The anti-collision bar is electrically connected to the controller; And / or, also includes a discharge indicator light; The unloading indicator light is located in the unloading room and is electrically connected to the controller.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0026] The following is combined with Figures 1 to 3 The present invention will provide a detailed description of the kitchen waste truck and unloading system provided in the embodiments of the present invention through specific implementation methods and application scenarios.

[0027] Firstly, such as Figure 1 As shown, this embodiment provides a food waste truck 1, including: a vehicle body 11, a hopper 12 and an unloading pipe 13.

[0028] The hopper 12 is located on the vehicle body 11 and is used to store kitchen waste. The bottom of the hopper 12 has a discharge port 121.

[0029] One end of the unloading pipe 13 is connected to the unloading port 121, and the other end of the unloading pipe 13 is opposite to the storage bin 21 of the unloading system, so as to guide the kitchen waste from the hopper 12 to the storage bin 21; an unloading control valve 14 is installed inside the unloading pipe 13, which is used to control the opening and closing of the unloading pipe 13.

[0030] Understandably, the vehicle body 11 in this embodiment includes a cab 111 and a loading mechanism. The cab 111 is located at the front of the vehicle body 11, where the driver controls and operates the vehicle. It is equipped with air conditioning and has a built-in control system 16. The control system 16 is a 12.3-inch touch screen. The control system 16 in the cab 111 can wirelessly connect with the controller 24 of the unloading system. The vehicle body 11 in this embodiment is equipped with 120L and 240L garbage bins. The loading mechanism is chain-driven and uses a side-tipping method to load kitchen waste into the hopper 12.

[0031] The hopper 12 in this embodiment is used to store kitchen waste. It has a cylindrical structure and is made of stainless steel, specifically 304 grade stainless steel. The discharge port 121 is located at the bottom of the hopper 12 and is connected to the discharge pipe 13. The discharge pipe 13 is used to guide the kitchen waste to prevent the kitchen waste flowing out of the discharge port 121 from not accurately entering the storage bin 21 and causing waste to splash out.

[0032] Specifically, the unloading pipe 13 can also be made of stainless steel with grade 304.

[0033] A discharge control valve 14 is installed on the inner wall of the discharge pipe 13. The discharge control valve 14 can open and close the passage between the discharge pipe 13 and the hopper 12.

[0034] Specifically, in this embodiment, the unloading control valve 14 is controlled by a hydraulic system, which is electrically connected to the control system 16 of the cab 111.

[0035] Because the vehicle body 11 in this embodiment has a discharge port 121 at its bottom, and the kitchen waste is guided from the hopper 12 to the storage bin 21 through the discharge pipe 13, the storage bin 21 is located on the lower side of the vehicle body 11. When unloading, the kitchen waste truck 1 does not need to tip the hopper 12 backward as in the prior art. It only needs to open the discharge control valve 14 in the discharge pipe 13 to ensure that the discharge pipe 13 is unobstructed, and the kitchen waste can be unloaded under the action of gravity. Since the discharge port 121 is located at the bottom of the vehicle body 11, the discharge path is downward along the discharge port 121, and there will be no significant shift in the center of gravity, so there is no risk of the kitchen waste truck 1 tipping over. Furthermore, since the discharge path is located below the discharge port 121 and also below the vehicle body 11, no additional working space is required, realizing flexible unloading of the kitchen waste truck 1. When a garbage truck tipps over, the rear cover needs to be fully opened before unloading. Food waste flows obliquely into the storage hopper 21 through the rear cover, resulting in a larger volume of exposed food waste and a higher concentration of odor emitted, requiring a larger volume of odor to be treated. In contrast, in this embodiment, the hopper 12 is connected to the storage hopper 21 via the unloading pipe 13. Odor only overflows through the gap between the bottom of the unloading pipe 13 and the top of the storage hopper 21. The concentration and volume of odor are lower, and the amount of odor requiring treatment is also smaller.

[0036] The food waste truck 1 provided by this invention has a discharge port 121 at the bottom of the hopper 12, and the discharge port 121 is connected to the storage bin 21 of the unloading system through the discharge pipe 13. A discharge control valve 14 is provided on the inner wall of the discharge pipe 13 to control the opening and closing of the discharge pipe 13. When the food waste truck 1 travels above the storage bin 21, the food waste in the hopper 12 can flow into the storage bin 21 through the discharge port 121 under the action of gravity through the guide effect of the discharge pipe 13. The required working space is small. When unloading, the center of gravity of the vehicle body 11 is consistent with the center of gravity of the food waste, so there is no risk of tipping over. Moreover, the conveying path of the food waste from the hopper 12 to the storage bin 21 is short, and the odor leakage is less. This not only improves the unloading efficiency of food waste, improves the unloading working environment, reduces the safety risk of unloading, reduces the cost of odor treatment, but also improves production efficiency and operational stability.

[0037] like Figure 1As shown, in this embodiment, the side wall of the hopper 12 connected to the discharge port 121 is inclined at an angle of 3‰.

[0038] Understandably, in order to ensure the smooth flow of kitchen waste in the hopper 12 to the unloading pipe 13, this embodiment sets the side wall of the hopper 12 connected to the unloading port 121 at an angle of 3‰.

[0039] In this embodiment, a shaftless screw is installed inside the hopper 12 to push the kitchen waste to the discharge port 121 during unloading.

[0040] Understandably, in order to increase the speed at which the kitchen waste in the discharge port 121 moves toward the discharge pipe 13, this embodiment installs a shaftless screw inside the hopper 12. Driven by the drive device, the screw blades rotate inside the hopper 12 and directly contact the kitchen waste, pushing the kitchen waste in the hopper 12 into the discharge port 121 and into the discharge pipe 13.

[0041] Specifically, in this embodiment, two shaftless screws are symmetrically installed on the side of the discharge port 121 inside the hopper 12. Under the dual action of screw pushing and gravity discharge, the kitchen waste in the hopper 12 quickly passes through the discharge pipe 13 and enters the storage bin 21, which improves the discharge efficiency.

[0042] The unloading time in this embodiment is less than or equal to 180 seconds.

[0043] like Figure 1 As shown, the food waste truck 1 in this embodiment also includes a camera 15.

[0044] The camera 15 is mounted on the vehicle body 11 and faces the unloading pipe 13.

[0045] Understandably, in order to monitor the unloading process and status of the unloading port 121 in a timely manner, this embodiment sets up a camera 15 on the outside of the unloading pipe 13. The camera 15 is connected to the control system 16 of the cab 111 and can feed back the image signal to the control system 16 in a timely manner so as to know whether the kitchen waste in the unloading pipe 13 has been unloaded.

[0046] Specifically, in this embodiment, the camera 15 is a PTZ camera that can rotate 360 ​​degrees to adjust the angle facing the unloading pipe 13 in real time. The camera 15 has a resolution of 1080P (1920×1080) and a resolution of 720 TVL.

[0047] Secondly, such as Figure 2 and Figure 3 As shown, this embodiment provides an unloading system, including: a kitchen waste truck 1, an unloading room 2, and a receiving pipe 22.

[0048] The unloading room 2 includes a first space located on the ground and a second space located underground. The first space and the second space are connected. The first space is used to form a closed space when the food waste truck 1 is unloading. The second space is equipped with a storage bin 21, which is used to store the unloaded food waste truck 1.

[0049] The receiving pipe 22 is vertically mounted at the connection between the first space and the second space and is connected to the storage bin 21. A receiving control valve 23 is installed inside the receiving pipe 22, which is used to control the opening and closing of the receiving pipe 22.

[0050] Specifically, since the unloading system includes a kitchen waste truck 1, and the specific structure of the kitchen waste truck 1 is as described in the above embodiments, the unloading system shown in this embodiment includes all the technical solutions of the above embodiments. Therefore, it has at least all the beneficial effects achieved by all the technical solutions of the above embodiments, which will not be described in detail here.

[0051] Understandably, the unloading room 2 in this embodiment is a closed work area, constructed of reinforced concrete and designed to be airtight. This allows the food waste truck 1 to unload within the enclosed space after entering the unloading room 2, preventing odor from escaping and harming the surrounding environment. The storage bin 21 is used to store the unloaded food waste from the food waste truck 1 for subsequent processing.

[0052] The first space of the unloading chamber 2 is located on the ground for the passage and unloading of the food waste truck 1. The second space of the unloading chamber 2 is located underground, and the storage bin 21 is located in the second space, i.e., the storage bin 21 is located underground. The first space and the second space are connected on the ground. To prevent food waste from leaking out due to the height gap between the unloading pipe 13 and the storage bin 21, this embodiment also provides a receiving pipe 22 on the ground. The receiving pipe 22 can be raised and lowered relative to the ground. One end of the receiving pipe 22 is connected to the storage bin 21, and the other end can be raised and lowered relative to the ground.

[0053] The receiving pipe 22 has a flexible structure. It rises during unloading, gradually approaches the unloading pipe 13, and falls below ground level after unloading, where it is housed in the storage bin 21. The raising and lowering of the receiving pipe 22 is controlled by a hydraulic system, which is connected in communication with the controller 24 of the unloading system.

[0054] Furthermore, in order to control the opening and closing of the receiving pipe 22, this embodiment has a receiving control valve 23 installed inside the receiving pipe 22, and the receiving control valve 23 is also connected in communication with the controller 24 of the unloading system.

[0055] Specifically, the receiving control valve 23 can be a stainless steel gate valve, with the movement of the gate controlled by a hydraulic system.

[0056] In practical application, when the food waste truck 1 is parked on the ground of the second space, waiting for the unloading operation, the controller 24 controls the receiving pipe 22 to rise, the receiving control valve 23 to open, and controls the unloading control valve 14 to open. At this time, the hopper 12, unloading pipe 13, receiving pipe 22, and storage bin 21 are all connected. The food waste truck 1 begins to unload into the storage bin 21. After the food waste in the hopper 12 is unloaded, the controller 24 controls the unloading control valve 14 to close, the receiving pipe 22 to descend, and the receiving control valve 23 to close, completing the unloading process of the food waste truck 1.

[0057] Since the storage bin 21 is located underground in the unloading room 2, the floor area of ​​the unloading room 2 is reduced by more than 50%, and the unloading time is reduced from 10 minutes in the existing technology to 3 minutes, improving efficiency by more than 70%.

[0058] The unloading system provided by this invention places the storage bin 21 below the ground of the unloading room 2, and sets up a receiving pipe 22 at the entrance of the storage bin 21. The receiving pipe 22 can be raised and lowered relative to the ground, and a receiving control valve 23 is set inside the receiving pipe 22. When unloading the garbage and kitchen waste truck, the hopper 12 is aligned with the entrance of the storage bin 21, the receiving pipe 22 is raised to approach the unloading pipe 13, and the receiving control valve 23 and the unloading control valve 14 are opened, so that the hopper 12 and the storage bin 21 can be connected. This enables the unloading operation to be carried out in a fully enclosed environment of the unloading room 2, avoiding the overflow of odors. Furthermore, since the hopper 12 and the storage bin 21 are set up directly opposite each other, the unloading path of the kitchen waste is the shortest, which improves the unloading speed and thus improves the production efficiency.

[0059] like Figure 2 and Figure 3 As shown, the unloading system in this embodiment also includes a controller 24, an inlet isolation door 25, and an outlet isolation door 26.

[0060] The first space has a first opening and a second opening, which are spaced apart. The first opening is equipped with an entrance isolation door 25, which can open and close the first opening. The second opening is provided with an exit isolation door 26, which can open and close the second opening.

[0061] The controller 24 is electrically connected to the entrance isolation door 25 and the exit isolation door 26 respectively.

[0062] Understandably, to facilitate the entry and exit of the food waste truck 1 into the enclosed space of the unloading room 2, this embodiment provides a first opening and a second opening in the first space. The first opening is equipped with an entrance isolation door 25, and the second opening is equipped with an exit isolation door 26. The controller 24 can control the opening and closing of the entrance isolation door 25 and the exit isolation door 26 respectively. The entrance isolation door 25 and the exit isolation door 26 can also be manually controlled on-site by staff.

[0063] When the food waste truck 1 needs to enter the first space, the entrance isolation door 25 is opened. After the food waste truck 1 enters the first space, the entrance isolation door 25 is closed, making the first space a sealed unloading space. After the food waste truck 1 has finished unloading, the exit isolation door 26 is opened to facilitate the food waste truck 1 to drive out of the first space. After the food waste truck 1 leaves the unloading room 2, the exit isolation door 26 is closed.

[0064] Specifically, the door frames of the entrance isolation door 25 and the exit isolation door 26 are both made of 304 stainless steel, and the door curtains are made of PVC coated cloth with a fluorocarbon coating (thickness ≥60μm) on the surface. The pH value is resistant to acids and alkalis in the range of 2~12, and can resist corrosion from substances such as hydrogen sulfide.

[0065] like Figure 2 and Figure 3 As shown, the unloading system in this embodiment also includes: an inlet position detection sensor 27, an outlet position detection sensor 28, and an unloading position detection sensor 29.

[0066] Along the direction of travel of the food waste truck 1, the entrance position detection sensor 27 is located behind the entrance isolation door 25, the exit position detection sensor 28 is located in front of the exit isolation door 26, and the unloading position detection sensor 29 is located in front of the storage bin 21.

[0067] The inlet position detection sensor 27, the outlet position detection sensor 28, and the unloading position detection sensor 29 are all electrically connected to the controller 24. Based on the position information of the kitchen waste truck 1 fed back by the inlet position detection sensor 27, the outlet position detection sensor 28, and the unloading position detection sensor 29, the controller 24 controls the opening and closing of the inlet isolation door 25 and the outlet isolation door 26.

[0068] Understandably, the entrance positioning sensor 27 is used to detect whether the food waste truck 1 has reached the outside of the entrance isolation door 25, the exit positioning sensor 28 is used to detect whether the food waste truck 1 has left the unloading room 2, and the unloading positioning sensor 29 is used to detect whether the food waste truck 1 is located on the upper side of the second space.

[0069] Furthermore, in order to give the driver an intuitive sense of their location, the entrance positioning sensor 27, the exit positioning sensor 28, and the unloading positioning sensor 29 in this embodiment are all set up with a vehicle speed reduction barge structure. They are composed of yellow and black rubber speed reduction barge units and are set on the ground of the unloading room 2. They are equipped with a geomagnetic and radar dual sensing module and transmit the corresponding positioning signal to the controller 24.

[0070] Specifically, the inlet position detection sensor 27 is located 2m behind the inlet isolation door 25, the unloading position detection sensor 29 is installed 4m behind the outlet isolation door 26, and the outlet position detection sensor 28 is installed 2m in front of the outlet isolation door 26.

[0071] In practical application, when the food waste truck 1 reaches the entrance positioning sensor 27, the positioning signal is fed back to the controller 24. The controller 24 controls the entrance isolation door 25 to open. The food waste truck 1 continues to move forward to the unloading positioning sensor 29, where the positioning signal is fed back to the controller 24. The controller 24 sends the positioning signal of the food waste truck 1 to the control system 16 of the food waste truck 1. The control system 16 controls the food waste truck 1 to stop. At the same time, the controller 24 controls the entrance isolation door 25 to close, so that the unloading chamber 2 forms a sealed space for unloading. After unloading is completed, the controller 24 controls the exit isolation door 26 to open, and the food waste truck 1 leaves the unloading chamber 2. When the food waste truck 1 reaches the exit positioning sensor 28, the positioning signal is fed back to the controller 24. After a delay, the controller 24 controls the exit isolation door 26 to close.

[0072] Specifically, the delay time can be 30 seconds.

[0073] like Figure 2 and Figure 3 As shown, the unloading system in this embodiment also includes a crash bar 30.

[0074] Along the direction of travel of the kitchen waste truck 1, the anti-collision bar 30 is raised and lowered and installed next to the unloading position detection sensor 29; the anti-collision bar 30 is electrically connected to the controller 24.

[0075] Understandably, the anti-collision bar 30 is located between the unloading position detection sensor 29 and the exit isolation door 26, and is used to limit the travel position of the food waste truck 1 when it enters the unloading room 2 to wait for unloading, so as to avoid the food waste truck 1 being unable to face the storage bin 21 due to the excessive travel distance.

[0076] Multiple anti-collision bars 30 can be provided, and the multiple anti-collision bars 30 are evenly spaced along the width direction of the unloading chamber 2.

[0077] Optionally, the anti-collision bar 30 is installed at a distance of 1.5 meters from the exit isolation door 26. There are six anti-collision bars 30, all of which are round bars made of stainless steel. The anti-collision bars 30 are hydraulically lifted and lowered. After being lowered, the top of the anti-collision bar 30 is flush with the ground of the unloading room 2.

[0078] In practical applications, when the entrance isolation door 25 is opened, the anti-collision bar 30 rises; when the material receiving control valve 23 of the storage bin 21 is closed, the anti-collision bar 30 falls.

[0079] likeFigure 2 and Figure 3 As shown, the unloading system in this embodiment also includes an unloading indicator light 35.

[0080] The unloading indicator light 35 is located in the unloading room 2. The unloading indicator light 35 is electrically connected to the controller 24. The controller 24 controls the opening and closing of the unloading indicator light 35 according to the opening and closing status of the receiving control valve 23.

[0081] Understandably, the unloading indicator light 35 is used to indicate the unloading process, allowing staff to intuitively understand the progress. The unloading indicator light 35 can be installed on the wall of the unloading room 2. When the unloading indicator light 35 is on, it indicates that the unloading room 2 is in the unloading state; when the unloading indicator light 35 is off, it indicates that the unloading room 2 is in the unloading state.

[0082] In practical applications, the unloading indicator light 35 is linked with the receiving control valve 23. After the receiving control valve 23 is opened, the controller 24 controls the unloading indicator light 35 to turn on. After the receiving control valve 23 is closed, the controller 24 controls the unloading indicator light 35 to turn off.

[0083] like Figure 2 and Figure 3 As shown, the unloading system in this embodiment also includes a limiting device.

[0084] The limiting device includes: a detection alarm 33 and a limiting guide rail 31.

[0085] Two limiting guide rails 31 are provided, and the two limiting guide rails 31 are spaced apart on both sides of the storage bin 21. The limiting guide rails 31 extend along the travel direction of the kitchen waste truck 1.

[0086] The detector 33 is located on the upper side of the limit rail 31, with the detection end of the detector 33 facing the limit rail 31.

[0087] The detector alarm 33 is electrically connected to the controller 24.

[0088] Understandably, there are two limiting guide rails 31, which are arranged in parallel and protrude from the ground of the unloading room 2. The width of the tires of the kitchen waste truck 1 is less than the distance between the two limiting guide rails 31, and the limiting guide rails 31 constrain the kitchen waste truck 1 to the inside of the two limiting guide rails 31.

[0089] Specifically, the limiting guide rail 31 can be made of lightweight steel rail, which is semi-buried underground and about 10cm above the ground.

[0090] Meanwhile, this embodiment also includes a detection alarm 33, which can detect whether the food waste truck 1 deviates from its driving route and issue an alarm when the food waste truck 1 deviates from its track to remind the driver. The alarm signal is simultaneously fed back to the control system 16 in the driver's cab 111 and the controller 24 in the unloading room 2.

[0091] Specifically, the detector alarm 33 can be an infrared alarm.

[0092] In practical applications, the food waste truck 1, guided by the limit rails 31 on both sides, travels in the unloading room 2 towards the storage bin 21. When the vehicle body 11 deviates from its course, the detection alarm 33 detects the deviation and triggers an alarm signal, which is transmitted to the driver's cab 111 and the controller 24, allowing the driver to correct the course in time. If the food waste truck 1 deviates further, its tires will run over the limit rails 31, causing the vehicle body 11 to become obstructed and unable to move forward, allowing the driver to correct the course in time.

[0093] The detector alarm 33 set in this embodiment can automatically detect the driving trajectory of the kitchen waste truck 1 and alert the driver when it deviates from the track. The limiting guide rail 31 provides physical correction for the kitchen waste truck 1, constraining the kitchen waste truck 1 within the internal space of the two limiting guide rails 31, providing double protection for the driving trajectory of the kitchen waste truck 1, and ensuring the correctness of the kitchen waste truck 1 driving towards the storage room.

[0094] like Figure 2 and Figure 3 As shown, the limiting device in this embodiment also includes an indicator line 32; the indicator line 32 is located at the center of the two limiting guide rails 31.

[0095] Understandably, the indicator line 32 is used to indicate and guide the driving path of the kitchen waste truck 1. The indicator line 32 is installed at the center line of the two limit guide rails 31 on the ground of the unloading room 2.

[0096] Specifically, the indicator line 32 is made of white ceramic tile slices embedded in the floor of the unloading room 2.

[0097] like Figure 2 and Figure 3 As shown, the unloading system in this embodiment also includes a flow meter 34; the flow meter 34 is installed at the inlet of the storage bin 21 and is electrically connected to the controller 24.

[0098] Understandably, in order to accurately test the flow rate of kitchen waste flowing into the inlet of storage silo 21, a flow meter 34 is installed here in this embodiment. The flow meter 34 can monitor the inlet flow rate of storage silo 21 in a timely manner and feed the flow information back to the controller 24, so that the staff can know the storage status of storage silo 21 in a timely manner and predict whether it can accept more kitchen waste trucks 1 or whether further processing of kitchen waste in storage silo 21 is required.

[0099] Specifically, the flow meter 34 adopts a waterproof and corrosion-resistant design with a waterproof rating of IP68. It can output signals by cutting magnetic field lines through the rotation of a multi-bladed rotor.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
