Description

Technical Field

[0001] This utility model belongs to the field of waste collection technology, and in particular relates to a waste collection device for water surfaces. Background Technology

[0002] A surface garbage collection device is a specialized piece of equipment used to clean up floating garbage on the surface of water bodies such as rivers, lakes, and oceans. It uses mechanical transmission, water flow guidance, or manual operation to gather, collect, and transport floating objects such as plastic bottles, dead leaves, and foam from the water surface using structures such as dredging nets, conveyor belts, and floats. This effectively improves the aquatic ecological environment, maintains water cleanliness, and plays an important role in water environment protection and management.

[0003] Currently, most surface garbage collection equipment adopts a one-time operation mode, which can only collect garbage once. After the garbage is full, it needs to be frequently cleaned and retrieved manually, which is not only labor-intensive and time-consuming, but also reduces efficiency. It cannot meet the needs of long-term and large-scale surface cleaning. Moreover, this type of equipment has a simple structure and poor endurance, making it difficult to cope with complex water areas and sudden garbage accumulation. Utility Model Content

[0004] The purpose of this utility model is to provide a water surface garbage collection device. By setting up a lifting unit, it solves the problem that it can only be used for single-time retrieval. After the garbage is full, it needs to be frequently cleaned and retrieved manually, which is not only labor-intensive and time-consuming, but also reduces efficiency and cannot meet the needs of long-term and large-scale water surface cleaning. Moreover, this type of equipment has a simple structure and poor endurance, making it difficult to cope with complex water areas and sudden garbage accumulation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a surface garbage collection device, comprising an aluminum profile frame, and further comprising: a lifting part, which is installed on the aluminum profile frame and is used to lift the collection bin; and a quick-release part, which is set on the lifting part and is used to reinforce the collection bin to prevent it from falling. When the collection bin is full of garbage, the lifting part is activated, which will lift the collection bin, and during the lifting process, the quick-release part will reinforce the collection bin to prevent it from falling during the lifting and lowering process.

[0007] Furthermore, the lifting section includes a drive assembly mounted on an aluminum profile frame for providing power to the lifting section; and a lifting component mounted on the drive assembly for lifting the collection bucket. Using the drive assembly to move the lifting component to raise and lower the collection bucket reduces labor intensity and improves work efficiency.

[0008] Furthermore, the quick-release section includes a quick-release assembly, which is installed on the lifting assembly to reinforce the collection bin and prevent it from falling during lifting; and a collection assembly, which is installed on the quick-release assembly to filter the collection bin, separate water from garbage, and reduce the lifting pressure of the lifting section.

[0009] In the process of lifting the collection components, the quick-release components provide stability, the collection components filter the garbage and water on them, and the pressure of the lifting unit during the lifting process is reduced by draining water.

[0010] Furthermore, the drive assembly includes an intelligent module fixedly connected to an aluminum profile frame. A motor sleeve is fixedly connected to the back of the aluminum profile frame, and a motor is fitted on the motor sleeve. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. The rotating shaft passes through the aluminum profile frame and is rotatably connected to the aluminum profile frame. A crank is fitted on the outer wall of the rotating shaft.

[0011] Once the motor is started, it will drive the crank via the rotating shaft. The crank works in conjunction with the lifting component to complete the lifting and lowering operation of the collecting component with a small amount of movement.

[0012] Furthermore, the lifting assembly includes a rocker arm rotatably connected to the front of the aluminum profile frame, a connecting rod hinged to the end of the rocker arm away from the aluminum profile frame, a slide rail fixedly connected to the front of the aluminum profile frame, a slider slidably connected to the outer surface of the slide rail, a connecting rod hinged to the slider at the end of the connecting rod away from the rocker arm, and a hanging rod fixedly connected to the front of the slider.

[0013] During the rotation of the crank, the crank will cooperate with the rocker arm, so that the connecting rod connected to the rocker arm can drive the slider connected to it and the collecting component on it to slide on the slide rail, thereby completing the lifting of the collecting component.

[0014] Furthermore, the quick-release assembly includes a fixed slider mounted on a slide rail. Two slide rods are fixedly connected to the left side of the fixed slider. Movable sliders are slidably connected to the outer walls of the two slide rods. The movable sliders are adapted to the fixed sliders. Springs are wound around the outer walls of the two slide rods. One end of each spring is fixedly connected to the fixed slider, and the other end of each spring is fixedly connected to the movable slider. Limiting components are provided on the movable sliders. Thus, with the cooperation of the slide rods and springs, when disassembling the quick-release assembly, the fixed slider and the movable slider can be quickly disassembled by relying on the restoring energy of the springs.

[0015] Furthermore, the collection assembly includes a collection bucket fixedly connected to the front of the fixed slider. The top of the collection bucket has two grooves, and the inner walls of the two grooves are slidably connected to limit blocks. A filter bucket is fixedly connected to the side of the two limit blocks that are close to each other. A drain pipe is fixedly connected to the bottom of the collection bucket. A solenoid valve is provided on the drain pipe, and a handle ring is rotatably connected to the drain pipe. The handle ring is adapted to the hanging rod. The two limit blocks on the filter bucket and the two grooves on the collection bucket cooperate with each other to separate the filter bucket from the collection bucket, thereby facilitating the cleaning of the collection bucket.

[0016] Furthermore, the limiting component includes a screw fixedly connected to the left side of the fixed slider, the screw passing through the movable slider and slidably connected to the movable slider, and a manual knob threadedly connected to the outer wall of the screw; wherein, when fixing the fixed slider and the movable slider, rotating the manual knob on the outer wall of the screw causes the manual knob to move the fixed slider on the outer wall of the screw closer to the movable slider, thereby completing the assembly of the quick-release assembly.

[0017] This utility model has the following beneficial effects:

[0018] 1. By setting up a lifting section, when using this device, it must first be placed in the area requiring garbage collection. At this time, the intelligent module will take over the device. When the intelligent module detects that the collection bin is full of garbage, it will trigger the motor to start. The motor drives the crank to rotate through the shaft. The crank and the rocker arm work together to drive the connecting rod on the rocker arm. The movement of the connecting rod causes the slider connected to it to slide along the slide rail, thereby driving the collection bin to rise. During this process, the quick-release assembly provides stable support for the lifting and lowering of the collection bin to ensure smooth operation. At the same time, the filter bucket in the collection assembly will filter and separate garbage and sewage. After filtration, the sewage can be discharged in time by controlling the solenoid valve on the drain pipe. In this way, the load on the lifting section during lifting and lowering is effectively reduced, which not only reduces labor intensity but also improves work efficiency.

[0019] 2. By setting up a quick-release mechanism, when the collection bucket needs to be disassembled at the top, first remove the handle ring on it from the hanging rod of the lifting part, and then turn the manual knob on the screw to release the limit on the movable slider. At this time, under the reset action of the slide rod and the spring, the movable slider separates from the fixed slider, realizing the quick disassembly of the collection bucket from the lifting part. This design not only ensures the stability of the collection bucket during the lifting process, but also simplifies the fixing operation process, saving time and manpower.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5As shown, this utility model is a surface garbage collection device, including an aluminum profile frame 111, and further including: a lifting part 2, which is installed on the aluminum profile frame 111 and is used to lift the collection bin; and a quick-release part 3, which is set on the lifting part 2 and is used to reinforce the collection bin to prevent it from falling. When the collection bin is full of garbage, the lifting part 2 is activated, which will lift the collection bin. During the lifting process, the quick-release part 3 will reinforce the collection bin to prevent it from falling during the lifting process.

[0031] Lifting unit 2 includes a drive assembly 21 mounted on an aluminum profile frame 111 for providing power to the lifting unit 2; and a lifting assembly 22 mounted on the drive assembly 21 for lifting the collection bucket. Using the drive assembly 21 to drive the lifting assembly 22 to lift the collection bucket reduces labor intensity and improves work efficiency. The drive assembly 21 includes an intelligent module 211 fixedly connected to the aluminum profile frame 111. A motor sleeve 212 is fixedly connected to the back of the aluminum profile frame 111, and a motor 213 is fitted onto the motor sleeve 212. The output shaft of the motor 213 is fixedly connected to a rotating shaft 214 via a coupling. A rotating shaft 214 passes through the aluminum profile frame 111 and is rotatably connected to it. A crank 215 is sleeved on the outer wall of the rotating shaft 214. When the motor 213 is started, it drives the crank 215 through the rotating shaft 214. The crank 215 cooperates with the lifting assembly 22 to complete the lifting and lowering operation of the collecting assembly 32 with a small amount of movement. The lifting assembly 22 includes a rocker arm 221 rotatably connected to the front of the aluminum profile frame 111. A connecting rod 222 is hinged to the end of the rocker arm 221 away from the aluminum profile frame 111. A slide rail 223 is fixedly connected to the front of the aluminum profile frame 111. A slider 224 is slidably connected to the outer surface of the slide rail 223. The connecting rod 222 is located away from the rocker arm 221. One end of the rod 221 is hinged to the slider 224, and a hanging rod 225 is fixedly connected to the front of the slider 224. During the rotation of the crank 215, the crank 215 engages with the rocker arm 221, causing the connecting rod 222 on the rocker arm 221 to drive the connected slider 224 and its collection component 32 to slide on the slide rail 223, thereby lifting the collection component 32. By providing the lifting section 2, when using this device, it must first be placed in the area requiring garbage collection. At this time, the intelligent module 211 will take over the device. When the intelligent module detects that the collection bin 321 is full of garbage, it will trigger the motor 213 to start. The motor 213 drives the crank 225 through the rotating shaft 214. Rotating the crank 215 causes the crank 215 and rocker arm 221 to work together, which in turn drives the connecting rod 222 on the rocker arm 221 to move. The movement of the connecting rod 222 causes the slider 224 connected to it to slide along the slide rail 223, thereby lifting the collection bucket 321. During this process, the quick-release assembly 31 provides stable support for the lifting and lowering of the collection bucket 321, ensuring smooth operation. At the same time, the filter bucket 324 inside the collection assembly 32 filters and separates garbage and sewage. After filtration, the sewage can be discharged in time by controlling the solenoid valve 326 on the drain pipe 325. In this way, the load on the lifting part 2 during lifting and lowering is effectively reduced, which not only reduces labor intensity but also improves work efficiency.

[0032] The quick-release section 3 includes a quick-release assembly 31, which is mounted on the lifting assembly 22 to reinforce the collection bin and prevent it from falling during lifting; and a collection assembly 32, which is mounted on the quick-release assembly 31 to filter the collection bin, separating water from waste and reducing the lifting pressure on the lifting section 2. During the lifting process, the quick-release assembly 31 provides stability to the collection assembly 32, while the collection assembly 32 filters the waste and water on it and reduces the pressure on the lifting section 2 during lifting by draining water. Component 31 includes a fixed slider 311 mounted on a slide rail 223. Two slide rods 312 are fixedly connected to the left side of the fixed slider 311. Movable sliders 313 are slidably connected to the outer walls of the two slide rods 312. The movable sliders 313 are adapted to the fixed slider 311. Springs 314 are wound around the outer walls of both slide rods 312. One end of each spring 314 is fixedly connected to the fixed slider 311, and the other end is fixedly connected to the movable slider 313. Limiting elements are provided on the movable slider 313. Specifically, the connection between the slide rods 312 and the springs 312... With the cooperation of 14, when disassembling the quick-release assembly 31, the fixed slider 311 and the movable slider 313 can be quickly disassembled by relying on the reset energy of the spring 314. The collection assembly 32 includes a collection bucket 321 fixedly connected to the front of the fixed slider 311. The top of the collection bucket 321 has two grooves 322. The inner walls of the two grooves 322 are slidably connected to limit blocks 323. A filter bucket 324 is fixedly connected to the side of the two limit blocks 323 that are close to each other. A drain pipe 325 is fixedly connected to the bottom of the collection bucket 321. An electric current device is installed on the drain pipe 325. A handle ring 327 is rotatably connected to the solenoid valve 326 and the drain pipe 325. The handle ring 327 is adapted to the hanging rod 225. The two limiting blocks 323 on the filter bucket 324 cooperate with the two sliding grooves 322 on the collection bucket 321 to separate the filter bucket 324 from the collection bucket 321, thereby facilitating the cleaning of the collection bucket 321. The limiting component includes a screw 315 fixedly connected to the left side of the fixed slider 311. The screw 315 passes through the movable slider 313 and is slidably connected to the movable slider 313. A manual knob 316 is threadedly connected to the outer wall of the screw 315.In this design, when fixing the fixed slider 311 and the movable slider 313, the manual knob 316 on the outer wall of the screw 315 is rotated. This causes the manual knob 316 to move the fixed slider 311 closer to the movable slider 313, thus completing the assembly of the quick-release assembly 31. By providing the quick-release part 3, when the collection bucket 321 is raised to the top and needs to be disassembled, the handle ring 327 on it is first removed from the hanging rod 225 of the lifting part 2. Then, the manual knob 316 on the screw 315 is rotated to release the limit on the movable slider 313. At this time, under the reset action of the slide rod 312 and the spring 314, the movable slider 313 separates from the fixed slider 311, achieving quick disassembly of the collection bucket 321 from the lifting part 2. This design ensures the stability of the collection bucket 321 during the lifting process and simplifies the fixing operation, saving time and manpower.

[0033] A specific application of this embodiment is as follows: The intelligent device includes a garbage full detection module and a power supply module. The garbage full detection module includes an Arduino control terminal, which can precisely control the rotation degree of the motor. A GMS communication module is set to the right of the Arduino control terminal to send site information to the staff for accurate location. An ultrasonic sensor is set below the GMS communication module. By transmitting and reflecting ultrasonic waves, the distance of garbage in the bin is calculated. After reaching a certain value, a signal is sent outward via GMS. The power supply module includes a solar panel, which is installed above the intelligent module to reduce the damage to the module and act as a rain shield. An MMPT voltage regulator module is set below the solar panel to stabilize the voltage generated by the solar panel and avoid damage to the power supply caused by voltage fluctuations due to environmental factors. A power supply is set below the MMPT voltage regulator module and is connected to a step-down module.

[0034] Solenoid valve 326: It is a basic automated component that uses electromagnetic force to control fluid flow. It belongs to the actuator category and is widely used in fluid control systems in industrial fields. It controls the opening and closing of the valve by the attraction force generated by the electromagnet, thereby realizing the control of parameters such as fluid direction, speed, and flow rate. For example, ZDF solenoid valve is suitable for various fluids such as water, gas, oil, and steam. The ambient temperature range is -20℃ to 60℃, and the fluid temperature varies depending on the group. The standard voltage is AC220V, DC24V, etc.

[0035] When using this device, it must first be placed in the area requiring garbage collection. At this time, the intelligent module 211 will take over the device. When the intelligent module detects that the collection bin 321 is full of garbage, it will trigger the motor 213 to start. The motor 213 drives the crank 215 to rotate through the shaft 214. The crank 215 works in conjunction with the rocker arm 221, which drives the connecting rod 222 on the rocker arm 221 to move. The movement of the connecting rod 222 causes the slider 224 connected to it to slide along the slide rail 223, thereby lifting the collection bin 321. During this process, the quick-release assembly 31 provides stable support for the lifting and lowering of the collection bin 321, ensuring smooth operation. At the same time, the filter bin 324 inside the collection assembly 32 will filter and separate the garbage and sewage. After filtration is completed, Sewage can be discharged in a timely manner by controlling the opening of the solenoid valve 326 on the drain pipe 325. This effectively reduces the load on the lifting part 2 during lifting, which not only reduces labor intensity but also improves work efficiency. When the collection bucket 321 is lifted to the top and needs to be disassembled, first remove the handle ring 327 from the hanging rod 225 of the lifting part 2, and then turn the manual knob 316 on the screw 315 to release the limit on the movable slider 313. At this time, under the reset action of the slide rod 312 and the spring 314, the movable slider 313 separates from the fixed slider 311, realizing the quick disassembly of the collection bucket 321 from the lifting part 2. This design not only ensures the stability of the collection bucket 321 during lifting, but also simplifies the fixing operation process and saves time and manpower.
