DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] Embodiment 1 The present invention discloses a Figure 1-6 The cleaning device shown is mainly used for cleaning the inside of sludge pools, oil pools, various large sludge, crude oil, and sewage chemical storage tanks. The body 1 of the device is shaped like an inverted rubber raft and is an inflatable structure. The jet cleaning nozzles 2 with water are distributed at the front end of the body 1. There are about 4 nozzles, two of which are high-pressure nozzles with small flow and high flow rate, which can flush out the compacted stains and break up the stains; the other two are low-pressure nozzles with large flow and low flow rate, which are mainly used to dilute the stains and facilitate the suction of the suction pipe 3 in the cavity. A camera unit 4 is set in the middle of the upper surface of the body. The camera unit has its own lighting system. The system uses its own battery to meet the explosion-proof requirements. The spray device 5 is installed at the rear end of the body 1. The device consists of two pieces, and the two groups of spray devices can rotate horizontally. The two sets of injection devices are respectively connected to the two 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, and the connecting rod 7 is also rotatably connected to the pull rod 8, and the pull rod 8 is connected to a driving mechanism 9 for driving the pull rod to move forward and backward. The driving mechanism can be a structure that can realize linear telescopic movement, such as pneumatic or electric motor. The injection device 5 is used to spray outward to provide the vehicle body 1 with forward power. The injection device 5 uses an anti-static non-metallic material pipeline to supply air, and the overall weight is light.

[0021] A sewage suction pipe 3 is arranged in the cavity of the vehicle body 1. The diameter of the sewage suction pipe is about 10 cm. A filter is arranged at the lower end of the sewage suction pipe and in front of the sewage suction port to filter out impurities. The sucked stains are discharged through the connecting pipeline. A circle of power airbags 6 is arranged at the edge of the vehicle body cavity, i.e., the inner wall of the vehicle body. The bottom end of the power airbag 6 is open. High-pressure gas sprays gas to the lower end opening through the power airbag 6 to form an air pressure difference, and the equipment is floated by this pressure difference. At the same time, the sewage suction port sucks the stains while also drawing the surrounding air, which can increase the pressure difference, help the equipment float and discharge the stains.

[0022] The gas source of the injection device 5 and the power airbag 6 comes from the high-pressure gas supplied from the outside, which is supplied from the external high-pressure gas pump through the high-pressure gas transmission hose. Since similar environments usually contain a large amount of toxic and harmful gases, and are usually flammable and explosive. The gas source is supplemented with nitrogen, which is manufactured by a special nitrogen generator. The manufactured nitrogen is supplied to the air pump, and then supplied to the equipment after being pressurized by the air pump.

[0023] The inflatable car body is not inflated under normal circumstances, and an air valve is set on the car body 1. It is only inflated when in use. If the entrance of the use scenario is relatively large, it can be inflated immediately. If the entrance is narrow and it is difficult to enter, it can be inflated after entering. The airbag is equipped with a water-sensitive sensor and a small CO2 gas cylinder. When it contacts the liquid surface, it opens quickly to release gas and fill the car body. After use, the gas in the car body is released through the exhaust valve. If the outlet is small and the machine is inconvenient, it can be deflated in advance. The exhaust valve is electronically controlled and can be opened and closed by wireless control.

[0024] Compared with the previous manual method, both safety and efficiency have been greatly improved. The crawler machine has a large weight and crawls slowly in the dirt. Compared with the crawler type, which is also fast and efficient, the new equipment floats on the liquid surface, has less resistance and moves faster.

[0025] The control system observes the scene through the camera unit 4 and controls the two airflow injection ports to walk. The airflow injection ports can be turned.

[0026] The extracted water-containing stains are separated by a filter press to separate the stains and water. The stains are dried to meet environmental protection requirements. If the stains contain crude oil, an oil-water separation device can be installed.

[0027] Embodiment 2 This embodiment discloses a Figures 7 and 8The cleaning device for tank wall shown in the figure is similar to that of the first embodiment. It also uses an inflatable bladder-type vehicle body 1 to enter the tank through the container port on the tank top to clean the tank wall. The difference from the first embodiment is that the suction pipe 3 is removed in this embodiment, and the spray device 5 and the cleaning nozzle 2 are connected to the same water pipe. The spray device 5 is used to spray water outward to provide the driving force for the entire cleaning device to move forward. Now, to clean the tank wall, one is to manually enter the tank body for cleaning. The dirty oil or stains in the bottom of the tank must be cleaned up before entering the confined space to meet the safety conditions. After entering, a scaffold is built to clean the tank wall. Or it can be cleaned directly with a high-pressure water gun. Another method is mechanical cleaning. A mechanical arm is extended into the tank from the top of the tank, and then fixed, and the pipe wall is cleaned by the nozzle carried by the mechanical arm. The nozzle is far away from the tank wall, and the pipe wall can only be cleaned with a large amount of water. The cleaning quality of this method cannot be guaranteed, and the local position may not be cleaned, and the cleaning quality cannot meet the requirements. Only by opening the tank and entering the interior can the cleaning quality be known. And construction can only be carried out after the liquid level in the tank drops to the lowest point.

[0028] When the device of this embodiment is adopted, since the inlet of the tank container is relatively narrow, the bladder can be inflated without air first, and then inflated after entering the tank. A cleaning device, a driving device and a video device are arranged on the bladder type vehicle body.

[0029] What is different from the first embodiment is that the cleaning device in this embodiment comprises two water jet nozzles, and the cleaning angles of the nozzles are staggered in height, so that a larger area can be cleaned.

[0030] The driving device in the present embodiment is also two water jet nozzles. These two nozzles can adjust the horizontal angle to provide the power for the rubber raft to advance.

[0031] One is to provide power, and the other is to provide power to offset the reaction force when the cleaning device cleans the tank wall.

[0032] In this embodiment, the tank cleaning quality can be observed in real time through a video system.

[0033] The cleaning equipment of this embodiment does not need to wait for the liquid level in the tank to drop. It floats on the liquid surface. After the part exposed to the water surface is cleaned, the liquid level is gradually lowered, and it is lowered while cleaning. When the bottom is lowered, the tank wall is also cleaned. It greatly saves construction time and ensures the utilization rate of the tank body. It is safe and efficient.

[0034] The cleaning device is mainly reflected in safety, efficiency, environmental protection, cost, application range and other aspects, as follows: High safety performance Avoiding poisoning of personnel: In traditional manual tank cleaning methods, the tanks often contain harmful substances such as sulfur, ammonia, hydrocarbons, phenols, etc. Personnel need to enter storage tanks filled with flammable and explosive gases, toxic and harmful substances to work, facing extremely high safety risks such as poisoning, suffocation, and explosion. The device of this application can be operated remotely, and there is no need for personnel to enter the tank, which fundamentally avoids the operating risks of personnel in harsh environments. The entire process is remotely controlled and the operator can complete all work tasks without entering the tank, which greatly reduces the safety risks of personnel.

[0035] Reduce the risk of explosion: When cleaning the tank manually, the tools used may produce friction and sparks, which can easily cause flash explosions in the tank environment with flammable and explosive gases. The device of this application adopts an explosion-proof design and can operate safely in dangerous environments.

[0036] Prevent other accidents: The space for tank cleaning operations is limited, and manual operations may also face risks such as hypoxia and mechanical injuries. The device of this application can isolate the operator from the dangerous environment and reduce the accident rate.

[0037] The work efficiency is high and the cleaning speed is fast, which is much higher than the manual dredging speed and can greatly shorten the tank cleaning project cycle.

[0038] Continuous and stable operation: The machine does not need to rest and can work continuously for 24 hours. It can complete a large number of tank cleaning tasks in a short time and improve overall work efficiency.

[0039] Good cleaning effect and no dead angle cleaning: the device of the present application can flexibly shuttle to various corners of the tank, is not restricted by space, can reach the parts that are difficult to reach manually, realize comprehensive and thorough cleaning, and ensure that there is no sediment residue in the tank.

[0040] Good environmental benefits and reduced pollutant emissions: The efficient cleaning method of the device of this application can reduce the generation and leakage of waste and pollutants during the cleaning process, and reduce pollution to the environment.

[0041] Low overall cost and improved equipment utilization: Fast and efficient tank cleaning operations can put storage tanks into use faster, improve equipment turnover and utilization, and bring more economic benefits to the company.

[0042] It has a wide range of applications and is applicable to a variety of industries: it is not only suitable for cleaning various storage tanks in the petrochemical industry, but can also be used for dredging and cleaning of confined spaces such as sedimentation tanks, sewage treatment tanks in sewage treatment plants, etc.

[0043] Cleaning of different media: It can clean sediments and media of different properties, such as sludge, silt, garbage, etc., to meet various tank cleaning needs.

[0044] The device solves the problems of low efficiency and great safety hazards of traditional manual or tracked equipment in confined space operations through an inflatable body, powered airbag suspension, air jet drive and a combination of high and low pressure nozzles.

[0045] Existing technologies (such as crawler cleaning vehicles and robotic arm cleaning) require personnel to enter or rely on bulky equipment, while this device significantly improves safety and efficiency through floating design + pneumatic drive. The technical solution is not obvious. Using nitrogen as the power source ensures safety and reduces the risk of explosion.

[0046] The device is suitable for scenes such as storage tanks and sewage pools, and its practicality is clear.

[0047] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
