Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and specifically discloses a cleaning device. Background Technology

[0002] The accumulation of stains is an unavoidable consequence of industrial production and urban life. These stains not only occupy valuable space but can also cause secondary pollution to the environment. Cleaning stains can effectively prevent sewage system blockages, reduce sewage treatment costs, and protect the ecological environment. Currently, cleaning is mainly done manually, with more advanced stain cleaning equipment using tracked cleaning trolleys equipped with high-pressure nozzles at the front. Tracked machines are very heavy, require numerous supporting pipelines and equipment, move slowly through stains, have low cleaning efficiency, and cannot clean tank walls. For cleaning stains on the inner walls of tanks, current technology involves extending a robotic arm from the top of the tank and fixing it in place, using nozzles carried by the robotic arm to clean the pipe walls. The nozzles are far from the tank walls, requiring a large volume of water to clean the pipe walls. This method cannot guarantee the cleaning quality, and many storage tanks have various internal structures, so some areas may not be cleaned, resulting in unsatisfactory cleaning quality. The cleaning quality can only be determined by opening the tank and entering the interior. Furthermore, work can only begin after the liquid level inside the tank has dropped to its lowest point. There are safety hazards to workers, and there are injuries and fatalities every year when workers enter confined spaces for cleaning. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a cleaning device that significantly improves both safety and efficiency compared to previous manual methods.

[0004] A cleaning device includes a vehicle body, with a jetting device for providing forward propulsion at the rear end of the vehicle body and a plurality of cleaning nozzles for breaking up and diluting stains at the front end of the vehicle body.

[0005] A cleaning device includes a vehicle body with power airbags arranged around its perimeter. The lower end of each airbag has an air jet nozzle for providing buoyancy. The rear end of the vehicle body has a jetting device for providing forward propulsion. The front end of the vehicle body has multiple cleaning nozzles for breaking up and diluting dirt. The pressure and flow rate of the air and water can be adjusted via the rear-end equipment.

[0006] Preferably, the vehicle body is an inverted U-shaped structure, and the power airbag is disposed on the inner wall of the inverted U-shaped structure.

[0007] Preferably, the spraying device consists of two sets, each set of which is connected to both ends of the horizontal steering mechanism.

[0008] Preferably, the horizontal steering mechanism includes a connecting rod, the middle part of which is rotatably connected to the vehicle body, and a tie rod is rotatably connected to the connecting rod. The tie rod is connected to a drive mechanism for driving the tie rod to move back and forth.

[0009] Preferably, the cleaning nozzles are in two sets: one set is a high-pressure nozzle for dispersing stains, and the other set is a low-pressure nozzle for diluting stains.

[0010] Preferably, the cleaning nozzle is rotatably connected to the vehicle body.

[0011] Preferably, the vehicle body is an inflatable structure, and a water-sensitive sensor is installed at the bottom of the vehicle body.

[0012] Preferably, the vehicle body is equipped with an automatic exhaust valve.

[0013] Preferably, a camera unit is provided on the upper part of the vehicle body.

[0014] Preferably, a suction pipe is provided at the lower end of the vehicle body, and a filter screen is provided at the front end of the suction pipe.

[0015] Beneficial effects:

[0016] 1. This utility model suspends the vehicle body on the liquid surface through airflow nozzles, and the jet mechanism realizes the power and direction change of the movement direction. Compared with the previous manual method, both safety and efficiency are greatly improved. Compared with tracked cleaning equipment, it is faster, more efficient, has less resistance, and moves quickly.

[0017] 2. When using this device to clean tank walls, there's no need to wait for the liquid level inside the tank to drop.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Example 1

[0030] This utility model discloses a method such as Figure 1-6The cleaning device shown is primarily used for cleaning sludge pools, oil sludge pools, various large sludge, crude oil, and sewage chemical storage tanks. The device's vehicle body 1 is shaped like an inverted rubber raft and is an inflatable structure. Water jet cleaning nozzles 2 are distributed at the front of the vehicle body 1, approximately four in total. Two of these are high-pressure nozzles with low flow rates and high velocities, used to break up and disperse hardened dirt; the other two are low-pressure nozzles with high flow rates and low velocities, mainly used to dilute the dirt, facilitating suction from the suction pipe 3 within the cavity. A camera unit 4 is installed in the center of the upper surface of the vehicle body. This camera unit has its own lighting system, which utilizes an internal battery to meet explosion-proof requirements. Two spray devices 5 are installed at the rear of the vehicle body 1; these two sets of spray devices can rotate horizontally. Two sets of injection devices are each connected to both ends of the connecting rod 7 of the horizontal steering mechanism. The middle part of the connecting rod 7 is rotatably connected to the vehicle body 1. The connecting rod 7 is also rotatably connected to a pull rod 8, which is connected to a drive mechanism 9 for driving the pull rod to move back and forth. This drive mechanism can be pneumatic, electric motor, or other structures that can achieve linear telescopic motion. The injection devices 5 use air to provide forward propulsion for the vehicle body 1. The injection devices 5 use anti-static non-metallic material pipelines for air supply and are lightweight overall.

[0031] A suction pipe 3, approximately 10 cm in diameter, is installed inside the cavity of the vehicle body 1. A filter screen is installed at the lower end of the suction pipe, in front of the suction port, to filter out impurities. The sucked-up dirt is discharged through a connecting pipeline. A ring of power airbags 6 is installed around the edge of the vehicle body cavity, i.e., the inner wall of the vehicle body. The bottom end of the power airbags 6 is open. High-pressure gas is sprayed through the power airbags 6 to the lower end opening, creating an air pressure difference. This pressure difference is used to levitate the equipment. At the same time, the suction port draws in surrounding air while sucking up dirt, which can increase the pressure difference, helping the equipment to levitate and the dirt to be discharged.

[0032] The air supply for the injection device 5 and the power airbag 6 comes from an externally supplied high-pressure gas source, delivered via a high-pressure air pump through a high-pressure air delivery hose. Since such environments typically contain large amounts of toxic and harmful gases, and are often flammable and explosive, nitrogen is used as the air source. Nitrogen is produced by a specialized nitrogen generator. The produced nitrogen is then supplied to the air pump, pressurized, and supplied to the equipment.

[0033] The inflatable vehicle body is not inflated under normal circumstances; an air valve is installed on vehicle body 1. It is only inflated during use. If the inlet is large, inflation can be done beforehand. If the inlet is narrow and entry is difficult, inflation can be done after entry. The airbag contains a water-sensitive sensor and a small CO2 cylinder. Upon contact with the liquid surface, it quickly opens, releasing gas to inflate the vehicle body. After use, the gas in the vehicle body is released through the exhaust valve. If the outlet is small and the machine is inconvenient, the gas can be released beforehand. The exhaust valve is electrically controlled and its opening and closing can be controlled wirelessly.

[0034] Compared to the previous manual methods, both safety and efficiency have been greatly improved. Tracked machines are heavy and move slowly through filth. In contrast, the new machine is faster and more efficient at the same speed. The new equipment floats on the liquid surface, resulting in less resistance and faster movement.

[0035] The control system observes the situation on-site through camera unit 4 and manipulates the two air jet nozzles to move. The air jet nozzles can be steered.

[0036] The extracted water-containing stains are separated using a filter press to separate the stains from the water. The stains are then dried to meet environmental protection requirements. If the stains contain crude oil, an oil-water separator can be installed.

[0037] Example 2

[0038] This embodiment discloses a method such as Figures 7 to 8 The cleaning device shown is similar in structure to Embodiment 1. It uses an inflatable bladder-type vehicle 1, which enters the tank through a container opening on the top to clean the tank walls. Unlike Embodiment 1, this embodiment omits the suction pipe 3. The spray device 5 and the cleaning nozzle 2 are connected to the same water pipe, and the spray device 5 propels the entire cleaning device forward by spraying water outwards. Currently, there are two methods for cleaning tank walls: one is manual entry into the tank to clean the bottom of the tank to ensure safety before entering the confined space. After entering, scaffolding is erected for cleaning the tank walls. Alternatively, a high-pressure water gun can be used directly. Another method is mechanical cleaning. A robotic arm extends from the top of the tank and is fixed in place. The nozzle carried by the robotic arm cleans the pipe walls. Since the nozzle is far from the tank wall, a large amount of water is needed to clean the pipe walls. This method cannot guarantee the cleaning quality; some areas may not be cleaned, and the cleaning quality may not meet requirements. Only by opening the tank and entering can the cleaning quality be determined. Construction can only begin after the liquid level in the tank has dropped to its lowest point.

[0039] When using the device of this embodiment, since the inlets of the tank containers are relatively narrow, the bladder can be de-inflated initially and inflated after entering the tank. A cleaning device, a drive device, and a video device are installed on the top of the bladder-type vehicle body.

[0040] Unlike Embodiment 1, the cleaning device in this embodiment consists of two water jet nozzles with their cleaning angles staggered, allowing for the cleaning of a larger area.

[0041] In this embodiment, the driving device is also two water jet nozzles. These two nozzles can be adjusted at a horizontal angle to provide power for the rubber raft to move forward.

[0042] Firstly, it provides power; secondly, it provides power to counteract the reaction force generated when the cleaning device cleans the tank wall.

[0043] This embodiment allows for real-time observation of the tank cleaning quality via a video system.

[0044] The cleaning equipment in this embodiment does not require waiting for the liquid level in the tank to drop. It floats on the surface, and after the portion above the water is cleaned, the liquid level is gradually lowered while cleaning continues. Once the bottom is lowered, the tank wall cleaning is complete. This significantly saves time and ensures the tank's usability. It is safe and efficient.

[0045] This cleaning device excels in several aspects, including safety, efficiency, environmental protection, cost, and application scope, as detailed below:

[0046] High safety performance

[0047] Avoiding personnel poisoning: Traditional manual tank cleaning methods often involve tanks containing harmful substances such as sulfur, ammonia, hydrocarbons, and phenols. Personnel must enter the storage tanks filled with flammable, explosive gases and toxic substances to work, facing extremely high safety risks such as poisoning, suffocation, and explosion. The device proposed in this application can be operated remotely without personnel entering the tank, fundamentally avoiding the risks of personnel working in harsh environments. Its fully remote control operation allows operators to complete all tasks without entering the tank, greatly reducing personnel safety risks.

[0048] Reducing the risk of explosion: During manual tank cleaning, the tools used may generate frictional sparks, which can easily trigger a flash explosion in the presence of flammable and explosive gases inside the tank. The device in this application adopts an explosion-proof design, enabling safe operation in hazardous environments.

[0049] To prevent other accidents: The space for tank cleaning operations is limited, and manual operation may also face risks such as lack of oxygen and mechanical injury. The device in this application can isolate the operator from the hazardous environment and reduce the accident rate.

[0050] It has high work efficiency and fast cleaning speed, far exceeding the speed of manual dredging, and can greatly shorten the tank cleaning project cycle.

[0051] Continuous and stable operation: The machine does not need to rest and can work continuously for 24 hours, completing a large number of tank cleaning tasks in a short time and improving overall work efficiency.

[0052] Excellent cleaning effect with no dead corners: The device of this application can flexibly move through every corner of the tank, without spatial limitations, and can reach parts that are difficult for humans to reach, so as to achieve a comprehensive and thorough cleaning and ensure that there are no sediment residues inside the tank.

[0053] Good environmental benefits and reduced pollutant emissions: The efficient cleaning method of the device in this application can reduce the generation and leakage of waste and pollutants during the cleaning process, thereby reducing environmental pollution.

[0054] Low overall cost and improved equipment utilization: Fast and efficient tank cleaning operations enable storage tanks to be put into use more quickly, improve equipment turnover and utilization, and bring more economic benefits to enterprises.

[0055] It has a wide range of applications and is suitable for various industries: it is not only suitable for cleaning various storage tanks in the petrochemical industry, but also for sludge removal and cleaning of confined spaces such as sedimentation tanks and sewage treatment ponds in sewage treatment plants.

[0056] Cleaning for different media: It can clean sediments and media of different properties, such as oil sludge, silt, and garbage, to meet a variety of tank cleaning needs.

[0057] This device, through its inflatable vehicle body, powered airbag suspension, airflow jet drive, and combination of high and low pressure nozzles, solves the problems of low efficiency and significant safety hazards in confined space operations caused by traditional manual or tracked equipment.

[0058] Existing technologies (such as tracked cleaning vehicles and robotic arm cleaning) require personnel to enter or rely on bulky equipment, while this device, through its floating design and pneumatic drive, significantly improves safety and efficiency; the technical solution is not readily apparent. Using nitrogen as the power source ensures safety and reduces the risk of explosion.

[0059] This device is suitable for scenarios such as storage tanks and sewage ponds, and its practicality is clear.
