Description

An oil tank cleaning device Technical Field

[0001] This application relates to the field of oil tank cleaning technology, and specifically discloses an oil tank cleaning device. Background Technology

[0002] Fuel tanks (especially those commonly used at gas stations) will accumulate condensation due to temperature fluctuations after a period of use. This condensation accelerates the emulsification of the fuel stored in the tank, corrodes the tank walls, and gradually increases the amount of sludge adhering to the tank walls. All of these factors reduce the quality of the fuel, which can have a very adverse effect on vehicles using this fuel. Therefore, fuel tanks need to be cleaned regularly.

[0003] As for oil storage tanks, given the large number of gas stations in my country and the existence of some automatic oil tank cleaning devices, even without considering the effectiveness of these devices, the cost of using them would be extremely high due to the sheer number of oil storage tanks.

[0004] Therefore, for the vast majority of oil tank cleaning, the cleaning method is still manual cleaning, that is, workers manually clean the oil tanks. In other words, workers need to enter the tank to carry out the cleaning operation. Although this method is low-end, it is low-cost and can be controlled.

[0005] Currently, the biggest challenge in manually cleaning oil tanks is the shape of the tank's inner wall, which has many blind spots. Traditional cleaning devices cannot reach these blind spots. In view of this, the inventor proposes an oil tank cleaning device that allows workers to hold the device and enter the oil tank to effectively clean the inner wall corners. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that traditional handheld oil tank cleaning devices cannot effectively clean the dead corners inside the oil tank.

[0007] To achieve the above objectives, the present invention provides the following basic solution:

[0008] An oil tank cleaning device includes a water pipe connected to a booster, a fine-adjustment pressure handle installed on the water pipe, a storage tank connected to the water pipe, an outlet pipe connected to the storage tank, and a spraying assembly installed at the end of the outlet pipe.

[0009] A switch valve is provided at the connection between the storage box and the water outlet pipe, and dead angle mounting parts are rotatably connected around the storage box;

[0010] The spraying assembly includes a spray disc installed at the end of the water outlet pipe, a plurality of spray holes on the surface of the spray disc, and a connecting shaft rotatably connected to the spray disc. One end of the connecting shaft passes through a blocking disc provided on the spray disc to block the spray holes. The blocking disc has blocking holes.

[0011] The dead angle installation component includes a rotating shaft rotatably connected to the storage box, a rotating block mounted on the rotating shaft, and a dead angle nozzle set on the rotating block.

[0012] The principle and effect of this basic scheme are as follows:

[0013] 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device can effectively clean the dead corners of the inner wall of the oil tank, eliminate the threat of dead corners in the oil tank, and solve the problem that traditional handheld oil tank cleaning devices cannot effectively clean the dead corners of the inner wall of the oil tank.

[0014] 2. Compared with existing technologies, traditional methods of effectively cleaning dead corners often sacrifice the efficiency of cleaning over a large area by using small nozzles. This invention combines both methods, using a spray disc to solve the problem of overall cleaning efficiency and dead corner nozzles to solve the cleaning of dead corners that the spray disc cannot reach. Thus, the overall cleaning efficiency of this device is not reduced, and it can solve the problem of dead corners of oil tanks that the spray disc cannot reach.

[0015] 3. Compared with existing technologies, this invention features a dead-angle installation component, which includes a rotating shaft rotatably connected to the storage tank, a rotating block mounted on the rotating shaft, and a dead-angle nozzle mounted on the rotating block. The dead-angle nozzle is installed on the hollow shaft by rotating it. At this time, the blocking holes on the baffle plate are misaligned with the spray holes. When the dead-angle nozzle is not installed on the hollow shaft, the blocking holes on the baffle plate are aligned with the spray holes. When the dead-angle nozzle is installed, all the flow enters the dead-angle nozzle, ensuring sufficient flow. When the dead-angle nozzle is removed, all the flow flows through the spray holes, ensuring a wide-area spray cleaning effect.

[0016] 4. Compared with existing technologies, this device is more portable and more suitable for manual cleaning. It includes a water pipe connected to a booster, a fine-adjustment pressure handle installed on the water pipe, a storage tank connected to the water pipe, an outlet pipe connected to the storage tank, and a spraying assembly installed at the end of the outlet pipe. It is easy to hold.

[0017] 5. Compared with the prior art, this device is equipped with a fine-tuning pressure handle. Although there is a booster to ensure pressure, in actual cleaning environments, it is necessary to further increase the pressure range. Therefore, this device is equipped with a fine-tuning pressure handle to slightly adjust the water pressure to ensure smooth cleaning.

[0018] Furthermore, the water pipe is a flexible hose, and the fine-tuning pressure handle includes a cylinder fixed to the flexible hose, a groove around the cylinder, and a squeezing block disposed in the groove. The squeezing block can squeeze the flexible hose to change the inner diameter of the flexible hose, and the other end of the booster is connected to a water tank.

[0019] Furthermore, a groove is opened at the bottom of the water outlet pipe, and a connecting pipe is slidably connected in the groove. The connecting pipe is a through pipe, and the other end of the connecting pipe is connected to a cleaning agent pipe. The cleaning agent pipe is filled with cleaning liquid. The operator holds the connecting pipe and the fine-tuning pressure handle to achieve stable control.

[0020] Furthermore, it also includes a wiring stabilization structure, which is installed outside the oil tank. The wiring stabilization structure includes symmetrically arranged supports and two sets of winding wheels arranged between the supports. One set of winding wheels is used to wind and connect the water pipe, and the other set of winding wheels is used to wind and connect the cleaning agent pipe.

[0021] Furthermore, the savings box has grooves around its perimeter, the dead angle mounting piece is installed in the grooves, and the grooves are provided with an annular ring on one side of the fine-tuning pressure handle, and the rotating shaft is rotatably connected to the annular ring.

[0022] Furthermore, the rotating block is magnetically connected to the dead angle nozzle, and a connecting line is eccentrically provided at one end of the dead angle nozzle. A connecting wheel is provided inside the rotating block, and the connecting line is wound around the connecting wheel. After the rotating block and the dead angle nozzle are manually separated, the dead angle nozzle is installed on the spray plate.

[0023] Furthermore, the dead-angle nozzle includes one or more of the following: trapezoidal nozzle, triangular nozzle, diamond-shaped nozzle, and elliptical nozzle.

[0024] Furthermore, the connecting shaft is a hollow shaft, one end of which is placed in the spray disc and threaded to the inner wall of the spray disc, and the other end of which is connected to the dead angle nozzle. A connecting ring is provided on the outer circumference of the hollow shaft, and the connecting ring is used to seal the gap between the hollow shaft and the spray disc.

[0025] Furthermore, the dead angle nozzle is installed on the hollow shaft by rotating the hollow shaft. At this time, the blocking hole on the blocking plate is misaligned with the spray hole. When the dead angle nozzle is not installed on the hollow shaft, the blocking hole on the blocking plate is in the same position as the spray hole. Attached Figure Description

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] The reference numerals in the accompanying drawings include: water pipe 1, detergent pipe 2, fine-tuning pressure handle 3, storage box 4, groove 5, buckle 6, spray disc 7, connecting pipe 8, groove 9, rotating block 10, dead angle nozzle 11, spray hole 12, squeezing block 13, annular ring 14, connecting wheel 17, blocking disc 18, blocking hole 19, connecting shaft 20, bracket 21, winding wheel 22.

[0037] The embodiments are shown in Figures 1, 2, 3, 4, 5, 6, 7, and 8:

[0038] An oil tank cleaning device includes a water pipe 1 connected to a booster, a fine-adjustment pressure handle 3 installed on the water pipe 1, a storage tank 4 connected to the water pipe 1, an outlet pipe 1 connected to the storage tank 4, and a spraying assembly installed at the end of the outlet pipe 1.

[0039] Specifically:

[0040] Water pipe 1 is a flexible hose. The fine-tuning pressure handle 3 includes a cylinder fixed to the flexible hose, a groove 5 around the cylinder, and a squeezing block 13 set in the groove 5. The squeezing block 13 can squeeze the flexible hose to change its inner diameter. The other end of the booster is connected to the water tank. This device is equipped with a fine-tuning pressure handle 3. Although the booster ensures the pressure, in the actual cleaning environment, it is necessary to further increase the pressure range. Therefore, this device is equipped with a fine-tuning pressure handle 3 to slightly adjust the water pressure to ensure the smooth progress of cleaning.

[0041] Regarding the handheld device in this case: the bottom of the water outlet pipe 1 has a groove, and a connecting pipe 8 is slidably connected in the groove. The connecting pipe 8 is a through pipe, and the other end of the connecting pipe 8 is connected to a cleaning agent pipe 2. The cleaning agent pipe 2 is filled with cleaning liquid. The operator holds the connecting pipe 8 and the fine-tuning pressure handle 3 to achieve stable control.

[0042] The purpose of filling the cleaning agent tube 2 with cleaning liquid is to mix with the water in the water tube 1 to improve the cleaning effect.

[0043] Since this case requires human access to the oil tank, special attention needs to be paid to the wiring. Therefore, this case has set up a wiring stabilization structure, which is set outside the oil tank. The wiring stabilization structure includes symmetrically arranged brackets 21 and two sets of winding wheels 22 arranged between the brackets 21. One set of winding wheels 22 is used to wind and connect the water pipe 1, and the other set of winding wheels 22 is used to wind and connect the cleaning agent pipe 2.

[0044] Specifically: A winding wheel 22 is provided to connect the cleaning agent pipe 2 and the water pipe 1. The winding wheel 22 can be used to extend the cleaning agent pipe 2 and the water pipe 1. This is very convenient for the staff inside the oil tank and also increases their range of movement.

[0045] A switch valve is provided at the connection between the storage box 4 and the water outlet pipe 1, and dead angle mounting parts are rotatably connected around the storage box 4.

[0046] The system is equipped with a switch valve, which is mainly designed to store water in the storage tank 4 first, as shown in Figure 1. The diameter of the outlet pipe 1 is significantly smaller than that of the storage tank 4. The system of storing water first and then opening the switch valve to release water ensures that the water pressure entering the outlet pipe 1 is sufficiently high.

[0047] The dead angle installation component includes a rotating shaft rotatably connected to the storage box 4, a rotating block 10 mounted on the rotating shaft, and a dead angle nozzle 11 set on the rotating block 10. The dead angle nozzle 11 is used in conjunction with the spray disc 7 to achieve dead angle cleaning.

[0048] Regarding the dead angle mounting component: The storage box 4 has grooves 5 around its perimeter. The dead angle mounting component is installed in the grooves 5. The groove 5 is located on one side of the fine-tuning pressure handle 3 and has an annular ring 14. The rotating shaft is rotatably connected to the annular ring 14. The rotating block 10 is magnetically connected to the dead angle nozzle 11. One end of the dead angle nozzle 11 is eccentrically connected with a connecting line. The rotating block 10 has a connecting wheel 17 inside, and the connecting line is wound around the connecting wheel 17. After the rotating block 10 and the dead angle nozzle 11 are manually separated, the dead angle nozzle 11 is installed on the spray plate 7. When the dead angle nozzle 11 is not needed, the rotating block 10 and the dead angle nozzle 11 are magnetically connected.

[0049] The dead angle nozzle 11 includes one or more of trapezoidal nozzles, triangular nozzles, diamond nozzles and elliptical nozzles. It is mainly used at irregular joints of oil tanks to clean these irregular joints.

[0050] Regarding the spraying assembly: The spraying assembly includes a spray disc 7 installed at the end of the water outlet pipe 1, a plurality of spray holes 12 opened on the surface of the spray disc 7, and a connecting shaft 20 rotatably connected to the spray disc 7. One end of the connecting shaft 20 passes through the spray disc 7 and is provided with a blocking disc 18 that can block the spray holes 12. The blocking disc 18 has blocking holes 19.

[0051] Specifically: The connecting shaft 20 is a hollow shaft. One end of the hollow shaft is placed in the spray disc 7 and threadedly connected to the inner wall of the spray disc 7. The other end of the hollow shaft is connected to the dead angle nozzle 11. A connecting ring is provided on the outer circumference of the hollow shaft. The connecting ring is used to seal the gap between the hollow shaft and the spray disc 7. The dead angle nozzle 11 is installed on the hollow shaft by rotating the hollow shaft. At this time, the blocking hole 19 on the blocking disc 18 is misaligned with the spray hole 12. When the dead angle nozzle 11 is not installed on the hollow shaft, the blocking hole 19 on the blocking disc 18 is in the same position as the spray hole 12.

[0052] Specific implementation process:

[0053] First, if you need to clean the oil tank in a wide area, do not move the dead corner nozzle 11. There is a buckle 6 in the groove 5 position, so that the dead corner installation part is locked in the groove 5. At this time, all the water will be sprayed out from the spray hole 12 on the spray plate 7. You can use the spray hole 12 to clean the wide area.

[0054] The second step is to remove the corner nozzle 11 if it is necessary to clean the dead corners of the oil tank. Then, rotate the corner nozzle 11 onto the hollow shaft. Due to the rotation, the blocking hole 19 on the blocking plate 18 is misaligned with the spray hole 12. The water will not flow out from the spray hole 12, but only from the corner nozzle 11. The shape and small size of the corner nozzle 11 can be used to clean the dead corners or irregular areas of the oil tank.

[0055] This device solves the problem that traditional handheld oil tank cleaning devices cannot effectively clean the dead corners inside the oil tank.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
