Description

Technical Field

[0001] The utility model relates to the technical field of garbage cleaning and collecting vehicles, and more specifically to an amphibious garbage collecting vehicle. Background Art

[0002] Floating garbage on the water surface not only causes bad odor and eutrophication of water bodies, but also seriously affects the appearance of the city, the living environment of residents and the ecological environment of the water.

[0003] Existing literature ("Design and Research of Marine Garbage Treatment and Collection Vehicle" by Wang Qi and Weng Jiongzhou) discloses a marine trash can, which is made of a large fiber net and floats on the sea surface near the dock to collect garbage. It provides kinetic energy through a marine trash can set up near a dock or a dock through a shore water pump, and under the rotation of the water pump, a height difference is formed between the edge of the trash can and the surrounding sea level, so that the surrounding water body rushes into the "trash can", driving the floating garbage on the sea surface into the trash can, and completing the collection of nearby sea surface garbage. At the same time, the outlet of the water pump is connected to the seawater, and the seawater is discharged back into the sea to form a cycle. The garbage bag of the "marine trash can" is easy to disassemble and assemble, but it must be fixed on the shore, and can only collect garbage on the shore, and it cannot achieve the cleaning of underwater and shallow garbage.

[0004] In addition, the cleaning vehicles disclosed in the existing patent documents (CN217870204U-an amphibious garbage cleaning vehicle, CN112921922A-an amphibious garbage cleaning device) can only collect garbage on the beach and the water surface, and are also unable to clean up underwater and shallow shoal garbage.

[0005] Therefore, how to provide an amphibious garbage collection vehicle that can not only clean up garbage on the road, beach, and floating on the water, but also clean up garbage suspended in the water and settled in the shallows underwater is a problem that technicians in this field urgently need to solve. Utility Model Content

[0006] In view of this, the utility model provides an amphibious garbage collection vehicle which can not only clean up garbage on roads, beaches and floating on water surfaces, but also clean up garbage suspended in water and settled in underwater shallows.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An amphibious garbage collection vehicle, comprising:

[0009] An amphibious submersible, wherein a steering thruster and a lifting thruster are fixed on both sides of the amphibious submersible, a garbage collection chamber is provided inside the amphibious submersible, a plurality of first filter holes connected to the garbage collection chamber are provided on the bottom end surface of the amphibious submersible, a garbage self-suction inlet, a garbage delivery inlet and a garbage removal outlet connected to the garbage collection chamber are provided on the amphibious submersible, and a garbage collection cover and a garbage removal cover for opening and closing the garbage delivery inlet and the garbage removal outlet are provided on the amphibious submersible;

[0010] A screw propeller mechanism, the screw propeller mechanism being mounted on the bottom end surface of the amphibious submersible body;

[0011] A mechanical arm shovel, the mechanical arm shovel is fixed to the front end of the amphibious submersible body, and is used to put the scooped garbage into the garbage collection chamber through the garbage delivery port;

[0012] A garbage self-suction mechanism, wherein the garbage self-suction mechanism is fixed to the amphibious submersible body, and a self-suction port of the garbage self-suction mechanism is connected to the garbage self-suction port;

[0013] A garbage conveyor belt mechanism is arranged on the bottom surface of the garbage collection chamber and is used to transfer garbage to the rear side of the garbage collection chamber. A plurality of second filter holes are provided on the belt body of the garbage conveyor belt mechanism.

[0014] It can be seen from the above technical scheme that compared with the prior art, the utility model discloses an amphibious garbage collection vehicle. When the collection vehicle cleans up garbage on the road surface and the beach, the screw propeller mechanism drives the amphibious submersible to walk on the road surface or the beach, the garbage collection cover is opened, and the mechanical arm shovel scoops up the garbage on the road surface and the beach and puts it into the garbage collection chamber through the garbage delivery port, and then the garbage conveyor belt mechanism drives the garbage to the rear side of the garbage collection chamber for storage. In the process of garbage transportation, the tiny sand and gravel in the garbage are discharged through the first filter hole and the second filter hole, reducing the accidental collection of tiny sand and gravel. When the garbage needs to be dumped, the garbage retrieval cover is opened and the garbage can be taken out manually. When the collection vehicle cleans up the garbage floating on the water surface or the garbage suspended in the water, the collection vehicle is put into the water, and the amphibious submersible moves under the action of the screw propeller mechanism, turns under the action of the steering propeller, and rises and dives under the action of the lifting propeller. When it is necessary to collect garbage, the garbage self-suction mechanism works to reduce the pressure at the self-suction port, while the fluid pressure at the pollutant layer above the self-suction port is strong, so that the pollutants above are sucked into the garbage collection cavity through the self-suction port, and the collection of garbage on the water surface and in the water is realized. When the collection vehicle collects garbage in the underwater shoal, the garbage can be scooped up by a mechanical arm shovel and then placed into the garbage collection cavity through the garbage delivery port to realize the collection of garbage. Therefore, the collection vehicle can not only walk on the beach and use the mechanical arm shovel to realize the cleaning of garbage on the beach, but also dive into the water to self-adsorb and collect the garbage floating on the water surface and the garbage suspended in the water, and can also use the mechanical arm shovel to collect the garbage on the underwater shoal, which greatly improves the scope of garbage cleaning by the collection vehicle.

[0015] Furthermore, the screw propeller mechanism comprises:

[0016] A fixing frame, wherein the fixing frames are two and are respectively fixed to the front and rear sides of the bottom end surface of the amphibious submersible body, and both sides of each fixing frame are rotatably connected with a swing shaft;

[0017] Swing arm frames, the number of the swing arm frames being two, and both sides of the swing arm frames are fixedly connected to the corresponding swing shafts;

[0018] Steering motors, there are two steering motors, which are respectively fixed on the two fixing frames, and a driving swing arm is fixed on the driving end of each steering motor, and the driving swing arm is fixed to the corresponding swing arm frame;

[0019] The screw propellers are two in number, and both ends of the screw propellers are respectively fixedly connected to the two swing shafts located on the same side.

[0020] The beneficial effect of adopting the above technical solution is: the rotating motor drives the swing arm frame to swing, thereby realizing the swing of the screw propeller, and finally realizing the steering of the vehicle body.

[0021] Furthermore, the garbage self-suction mechanism comprises:

[0022] The garbage self-suction inner cylinder comprises: a conical cylinder and a straight cylinder, the large cylinder mouth end of the conical cylinder is fixed to and communicated with the garbage self-suction port, and the small cylinder mouth end of the conical cylinder is integrally connected to and communicated with the lower end of the straight cylinder;

[0023] A pressurized outer sleeve, wherein the pressurized outer sleeve is sleeved on the garbage self-suction inner sleeve, and the interlayer space between the two forms a pressurized chamber that is larger at the top and smaller at the bottom, the lower cylinder edge of the pressurized outer sleeve is fixed and sealed to the lower end of the tapered cylinder, the upper cylinder edge of the pressurized outer sleeve has a bent portion bent downward, the bent portion is inserted into the upper cylinder mouth of the straight cylinder, and the gap between the two forms an injection port, the pressurized chamber is connected with the upper cylinder mouth of the straight cylinder through the injection port, so as to form the self-suction port at the upper cylinder mouth of the straight cylinder;

[0024] A booster box, the booster box is fixed on the amphibious submersible body, and two opposite side walls of the booster box are respectively provided with a water inlet and a water outlet, and the water outlet is communicated with the booster chamber;

[0025] A boost mechanism is fixed in the boost box.

[0026] The beneficial effect of adopting the above technical scheme is: when the vehicle body collects garbage in the water, water enters the boosting box through the water suction port, and the boosting mechanism pressurizes the water to increase the flow rate of the water and discharges it into the boosting chamber through the water outlet. Because the lower space of the boosting chamber is narrow, the flow rate of the pressurized water will further increase after it flows into the lower space, and it will be further accelerated through the narrow injection port and then sprayed into the straight cylinder. Because the flow rate of the sprayed water is relatively large, according to Bernoulli's principle, the speed and pressure are inversely proportional. Therefore, the pressure at the upper barrel mouth of the straight cylinder, that is, the self-priming port, will decrease and be less than the strength of the fluid at the pollutant layer above the self-priming port. Due to the pressure difference, the pollutants above will be prompted to enter the self-priming port, thereby realizing the self-adsorption and collection function of garbage on the water surface and in the water.

[0027] Furthermore, the boosting mechanism comprises:

[0028] A boost motor, the boost motor being fixed in the boost box;

[0029] A supercharger turbine is arranged close to the water intake port and is fixedly connected to the driving end of the supercharger motor.

[0030] The beneficial effect of adopting the above technical solution is that the booster motor can drive the booster turbine to boost the water entering the booster box, thereby achieving initial boosting of the water flow.

[0031] Furthermore, the boost motor has dual drive ends, wherein the first drive end is fixed to the boost turbine, and the second drive end is fixed with an inducer, and the inducer is arranged close to the water outlet side.

[0032] The beneficial effect of adopting the above technical solution is that the guide wheel can guide the pressurized water to avoid the generation of a turbine at the water outlet and affecting the pressurized water from entering the supercharging chamber. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The garbage self-suction mechanism 8 comprises:

[0054] The garbage self-suction inner cylinder 81 includes: a conical cylinder 811 and a straight cylinder 812. The large cylinder mouth end of the conical cylinder 811 is fixed and connected to the garbage self-suction port 103, and the small cylinder mouth end of the conical cylinder 811 is integrally connected and connected to the lower end of the straight cylinder 812.

[0055] The pressurized outer sleeve 82 is sleeved on the garbage self-suction inner sleeve 81, and the interlayer space between the two forms a pressurized chamber 801 that is larger at the top and smaller at the bottom. The lower cylinder edge of the pressurized outer sleeve 82 is fixed and sealed to the lower end of the conical cylinder 811, and the upper cylinder edge of the pressurized outer sleeve 82 has a bent portion 821 bent downward, which is inserted into the upper cylinder mouth of the straight cylinder 812, and the gap between the two forms an injection port 802. The pressurized chamber 801 is connected to the upper cylinder mouth of the straight cylinder 812 through the injection port 802 to form a self-suction port 803 at the upper cylinder mouth of the straight cylinder 812;

[0057] The boost mechanism 84 is fixed in the boost box 83 .

[0058] The boost mechanism 84 includes:

[0059] A boost motor 841, the boost motor 841 is fixed in the boost box 83;

[0060] The supercharger turbine 842 is arranged close to the water suction port 831 , and the supercharger turbine 842 is fixedly connected to the driving end of the supercharger motor 841 .

[0061] The boost motor 841 has dual drive ends, wherein the first drive end is fixed to the boost turbine 842 , and the second drive end is fixed with a guide wheel 843 , which is arranged close to the water outlet 832 .

[0062] The amphibious submersible body 1 of the utility model is fixed with a sealed compartment 10 on the garbage removal cover 5, and the sealed compartment 10 can be placed with a rechargeable battery, a controller and other components for powering the device, and the device is also equipped with a camera, an obstacle avoidance radar, an antenna, a diving depth sensor and other components. The operator can remotely control the device through the picture transmitted to the remote control in real time through the camera. Of course, the device can also autonomously plan and navigate the path to improve the cleaning efficiency and accuracy.

[0063] The garbage collection principle of this utility model is as follows:

[0064] When the collection vehicle is cleaning up garbage on the road and the beach, the screw propeller drives the vehicle to move and turn. When it moves to the garbage location, the garbage collection cover is opened, the mechanical arm shovel scoops up the garbage and puts it into the garbage collection chamber through the garbage delivery port, and then the garbage conveyor belt mechanism drives the garbage to the back side of the garbage collection chamber for storage. During the garbage transportation process, the tiny sand and gravel in the garbage are discharged through the first filter hole and the second filter hole, reducing the accidental collection of tiny sand and gravel. When the garbage needs to be dumped, the garbage retrieval cover is opened and the garbage can be taken out manually.

[0065] When the collection vehicle cleans up the garbage floating on the water surface or the garbage suspended in the water, the garbage collection cover is closed, and then the collection vehicle is put into the water. The amphibious submersible body turns under the action of the steering thruster, rises and dives under the action of the lifting thruster, and moves under the action of the screw propeller. When it is necessary to collect garbage, the booster motor drives the booster turbine to rotate, and the water enters the booster box through the water suction port, and is discharged into the booster chamber through the water outlet after being boosted by the booster turbine. Because the lower space of the booster chamber is narrow and the upper space is large, the pressurized water flows into the lower space The flow velocity will further increase, and will be further accelerated after being ejected into the straight cylinder through the narrow injection port. Because the flow velocity of the ejected water is relatively large, according to Bernoulli's principle, speed and pressure are inversely proportional. Therefore, the pressure at the upper tube mouth of the straight cylinder, i.e., the self-priming port, will decrease and be lower than the strength of the fluid at the pollutant layer above the self-priming port. Due to the pressure difference between the two, the pollutants above will be prompted to enter the self-priming port and enter the garbage collection chamber. Then the garbage conveyor belt mechanism will drive the garbage to the back side of the garbage collection chamber for storage, thereby realizing the self-adsorption and collection function of garbage on the water surface and in the water.

[0066] When the collection vehicle collects garbage in an underwater shallow beach, the garbage can be scooped up by a mechanical arm shovel and then placed into a garbage collection chamber through a garbage placement port to realize the collection of the shallow beach garbage.

[0067] The advantages of this collection vehicle are as follows:

[0068] 1. The utility model can dive underwater through a lifting propeller to clean up garbage in rivers, lakes, oceans and other waters. Specifically, it can clean up the garbage suspended underwater, the garbage floating on the water surface and the garbage deposited on the bottom of the shallow water through adsorption and mechanical arm shovel, greatly improving the cleanliness of the water area.

[0069] 2. Because the device dives underwater, it is relatively stable and will not be disturbed by the water flow on the surface. It can clean up garbage more effectively. Underwater cleaning will not interfere with surface activities and the ecological environment, and can avoid causing harm to water birds, marine life, etc., and better protect the balance and health of the ecosystem.

[0070] 3. This collection vehicle is based on the principle of fluid vortex centripetal suction. The self-suction port of the garbage self-suction mechanism generates centripetal suction to suck the vortex downward, so that the fluid carries the suspended matter on the water surface in the vortex area and flows downward in a spiral, thereby realizing 360-degree no-dead-angle salvage of garbage in a certain nearby water area.

[0071] 4. The utility model adopts 4 lifting thrusters, 4 steering thrusters and 2 screw thrusters, which can provide a greater total thrust for the device, making the device less susceptible to the influence of water flow, and can clean up garbage more effectively. It also allows the device to carry more sensors, batteries and other equipment, improve the load carrying capacity of the device, and ensure its endurance.

[0072] 5. The utility model can realize 360-degree garbage cleaning without dead angles on the bottom of water, water surface and surrounding environment. It not only has a simple structure, but also has good garbage collection effect, high efficiency and strong practicality. It can achieve the effect of saving resources, protecting the environment, energy saving and emission reduction, and is conducive to the construction of a beautiful home of modern ecological civilization in my country.

The same or similar parts between the embodiments can be referred to each other. For the collection vehicle disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
