Description

Technical Field

[0001] This invention belongs to the field of oil tanker technology, specifically an oil tanker that is easy to clean. Background Technology

[0002] Tanker trucks, also known as mobile refueling trucks, computer-controlled tax refueling trucks, oil tankers, oil loading trucks, oil transport trucks, oil hauling trucks, petroleum transport trucks, and edible oil transport trucks, are mainly used for the transportation and storage of petroleum derivatives (gasoline, diesel, crude oil, lubricating oil, and coal tar, etc.).

[0003] The main purpose of cleaning the exterior of ordinary oil tankers is to keep the vehicle clean and aesthetically pleasing, reduce the corrosion of the exterior surface of the oil tanker by oil stains and impurities, and also to prevent road pollution and maintain good hygiene conditions.

[0004] In practice, the first step is to prepare by driving the tanker truck to a designated cleaning site and ensuring that the site has good drainage facilities to prevent wastewater from flowing everywhere during the cleaning process. Prepare various cleaning tools such as high-pressure water guns, cleaning brushes, and cleaning agents. Next, use the high-pressure water gun to rinse the exterior of the tanker truck to wash away surface dirt and dust. For some stubborn stains, use a cleaning brush with cleaning agent to wipe and clean them.

[0005] This cleaning method relies on manual operation and requires a special location to properly clean up the oily wastewater. This limits the cleaning of tank trucks. During periods of high-intensity operation, it is difficult to clean the outer surface of the tank trucks regularly and in a timely manner, which can easily lead to accelerated corrosion of the outer surface of the tank trucks and affect their service life.

The oil tanker includes a vehicle body and an oil tank. A support platform is provided at the bottom of the oil tanker and is fixed to the vehicle body. An equipment platform is provided at the top of the oil tanker.

[0007] The oil tank is provided with fixing sleeves on both ends, the fixing sleeves are located between the support platform and the equipment platform, and are fixed to the outer surface of the oil tank;

[0008] Arc-shaped cleaning rods are slidably provided on the outer surfaces of both sides of the oil tank. A cleaning groove is provided on the side wall of the oil tank where the cleaning rod contacts the cleaning rod. Brush bristles are evenly provided on the inner wall of the cleaning groove.

[0010] Preferably, the telescopic device is mounted on the fixed sleeve on the side near the rear of the vehicle body, and a replenishment cavity is provided inside the fixed sleeve on the side near the front of the vehicle body. The replenishment cavity is connected to the cleaning fluid tank on the support platform.

[0011] A supplementary hole is provided on the side wall of the supplementary cavity, opposite the push rod, and the end of the push rod is slidably embedded into the supplementary hole;

[0012] The cleaning rod has a cleaning cavity on its inner wall, which is connected to the supplementary cavity via a tubular push rod; the cleaning groove has a cleaning hole on its inner wall at the bristle gap, which is connected to the cleaning cavity.

[0013] Preferably, an inflation tube is provided in the middle part of the push rod, the inflation tube is connected to the inflation chamber on one side of the replenishment chamber, and a flushing tube is provided on the side wall of the inflation tube at the part corresponding to the cleaning hole, the open end of the flushing tube extending into the cleaning hole.

[0014] Preferably, the cleaning hole is a conical hole, with the smaller end located near the opening on the outer surface of the oil tank, and the opening end of the air inlet pipe is a conical pipe structure, with the larger end being the opening.

[0015] Preferably, a guide plate is uniformly provided on the inner wall of the cleaning tank at the location of the gap between the cleaning holes, and the guide plate is made of an elastic material; one end of the guide plate is elastically connected to the inner wall of the cleaning tank, and the other end of the guide plate is inclined towards the direction of the recycling tank.

[0022] The present invention discloses an easy-to-clean oil tanker. When cleaning is required, the driver can directly activate the telescopic device via the controller, which drives the push rod to move the connected cleaning rod laterally. The sliding cleaning rod scrapes the outer surface of the oil tank, causing the oil and impurities adhering to the outer surface of the oil tank to be removed more quickly. These impurities then flow downwards along the outer surface of the oil tank with the cleaning fluid. After the oil and impurities adhering to the oil tank surface are removed, they mix into the cleaning fluid and then flow downwards along the cleaning rod and the outer surface of the oil tank into the recovery tank of the bottom support platform. This facilitates the subsequent recycling and purification of the cleaning fluid containing these mixed oil and impurities, preventing the cleaning fluid containing oil and impurities from flowing around and causing pollution to the surrounding environment during the cleaning process.

[0023] This invention automates the scraping and scrubbing process by pushing the cleaning rod to achieve full coverage. This ensures more comprehensive cleaning of both sides of the oil tank, reducing the chance of missing oil stains or impurities in certain areas during the cleaning process. It also reduces manual labor while ensuring thorough cleaning of the outer surface of the oil tank, thereby extending the service life of the oil tank. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] As shown in the attached diagram of the instruction manual. Figures 1-7 As shown, this application proposes an easy-to-clean oil tanker. The oil tanker includes a vehicle body 1 and an oil tank 11. A support platform 12 is provided at the bottom of the oil tank 11. The support platform 12 is fixed to the vehicle body 1 and connected by bolt fasteners or directly welded to the frame on the rear side of the vehicle body 1. An equipment platform 13 is provided at the top of the oil tank. The equipment platform 13 is provided with oil outlet and oil inlet pipes, as well as relevant monitoring equipment for monitoring data such as internal temperature and pressure of the oil tank 11. The support platform 12 and the equipment platform 13 respectively cover the top and bottom of the oil tank 11, so that only the parts of the arc-shaped outer surface of the oil tank 11 near the two sides are directly exposed to the external environment. Therefore, a fixing sleeve 2 is provided on both ends of the oil tank 11. The fixing sleeve 2 is located between the support platform 12 and the equipment platform 13 and is fixed to the outer surface of the oil tank 11.

[0036] Arc-shaped cleaning rods 21 are slidably installed on the outer surfaces of both sides of the oil tank 11. Cleaning grooves 22 are provided on the side walls of the oil tank 11 where the cleaning rods 21 contact. Bristles are evenly arranged on the inner walls of the cleaning grooves 22. In addition, the fixing sleeves 2 cover and shield the joint between the two ends of the oil tank 11 and the side walls. The outer surface of the side walls of the oil tank 11 is also shielded and protected by the cleaning rods 21. In this way, when an external impact occurs, the fixing sleeves 2 and the cleaning rods 21 are limited to withstand the external impact and play a role in dispersing and supporting, reducing the direct impact on the oil tank 11 body, thereby reducing the probability of damage to the oil tank 11.

[0037] A push rod 23 is horizontally installed on the cleaning rod 21. The push rod 23 is connected to the output end of the telescopic device 24 on the fixed sleeve 2. The telescopic device here can be an existing electric telescopic device, which is controlled by the controller inside the cab to realize the lateral sliding of the cleaning rod 21. A recovery tank 121 is provided on both sides of the support platform 12. The bottom of the cleaning rod 21 is slidably embedded into the inlet of the recovery tank 121. The bottom of the recovery tank 121 is provided with a chamber structure, which can temporarily store the sewage mixed with oil generated during the cleaning operation. After reaching a place where it can be treated, the sewage is pumped to the external sewage treatment facility through the bottom interface to avoid causing pollution to the surrounding environment.

[0038] Specific workflow: During long-term operation, the outer surface of the oil tank 11 is directly exposed to the external environment. Due to the oil inlet and outlet process, oil stains adhere to the outer surface of the oil tank. The adhesiveness of the oil stains also causes external dust and impurities to adhere to them, forming a tightly adhered dirt on the outer surface of the oil tank 11. This dirt adheres to the outer surface of the oil tank 11, which can easily affect the appearance and hygiene of the outer surface of the oil tank. It can also easily lead to the aggravation of the corrosion on the outer surface of the oil tank 11, thereby increasing the possibility of leakage and damage to the oil tank 11, and even affecting the service life of the oil tank.

[0039] Therefore, this application uses cleaning rod 21 to automatically clean the oil stains and impurities adhering to the outer surface of oil tank 11, thereby ensuring that the outer surface of oil tank 11 is fully cleaned. Specifically, when cleaning is required, the driver can directly start the telescopic device 24 through the controller, which drives the push rod 23 to move the connected cleaning rod 21 laterally. The lateral movement is greater than the distance between adjacent cleaning rods 21, so that the outer surfaces on both sides of oil tank 11 are fully covered.

[0040] During the movement of the cleaning rod 21, the driver sprays cleaning fluid on the outer surface of the oil tank 11 in advance. The scraping action of the sliding cleaning rod 21 on the outer surface of the oil tank 11 promotes the rapid removal of oil and dirt adhering to the outer surface of the oil tank 11, and the cleaning fluid flows down the outer surface of the oil tank 11. The cleaning fluid is a special detergent used for cleaning oil in the prior art, which is mixed with clean water and pre-stored in the cleaning fluid tank inside the support platform 12.

[0041] Meanwhile, the bristles evenly distributed on the inner wall of the cleaning tank 22 sweep away the oil stains and impurities adhering to the outer surface of the oil tank 11. Combined with the cleaning fluid flowing from top to bottom, this accelerates the removal of oil stains and impurities from the surface of the oil tank 11, which then mix into the cleaning fluid. Subsequently, the fluid flows down the cleaning rod 21 and the outer surface of the oil tank 11 into the recovery tank 121 of the bottom support platform 12, facilitating the subsequent recycling and purification of the wastewater containing these mixed oil stains and impurities. This prevents the cleaning fluid containing oil stains and impurities from flowing around and causing pollution to the surrounding environment during the cleaning process. This automatic cleaning method eliminates the need for a driver to drive the oil tanker to a dedicated cleaning area for manual flushing and cleaning. This application allows for cleaning at the nearest parking location when cleaning is required, and the wastewater collected can be recycled and stored, reducing waste to the surrounding environment.

[0042] Furthermore, compared to manual rinsing by handheld nozzles, this application achieves more automated cleaning by pushing the cleaning rod 21 to fully cover the scraping and brushing direction. The cleaning effect more comprehensively covers both sides of the oil tank 11, reducing the possibility of local oil stains and impurities being missed by manual cleaning. This reduces manual input while ensuring thorough cleaning of the outer surface of the oil tank 11, thereby ensuring the service life of the oil tank 11.

[0043] Example 2:

[0044] Based on Embodiment 1, regarding the use of cleaning fluid, in addition to the existing technology of directly spraying with a water gun or applying with tools such as a brush, this embodiment provides a more efficient way of using it. The telescopic device 24 is set on the fixed sleeve 2 on the side near the rear of the vehicle body 1. The fixed sleeve 2 on the side near the front of the vehicle body 1 is provided with a replenishment chamber 25. The replenishment chamber 25 is connected to the cleaning fluid tank inside the support platform 12. The cleaning fluid tank is filled with cleaning fluid and is connected to the replenishment chamber 25 through a pipe. A water pump device is set in the middle of the pipe. During the cleaning operation, the cleaning fluid is pumped into the replenishment chamber 25 through the pipe for cleaning.

[0045] A replenishment hole 251 is provided on the side wall of the replenishment cavity 25, directly opposite the push rod 23. The end of the push rod 23 slides through the replenishment hole 251 and is embedded in the replenishment cavity 25. During the lateral reciprocating movement of the push rod 23, the end of the push rod 23 remains inside the replenishment cavity 25 and will not collide with the inner wall of the replenishment cavity 25. A cleaning cavity 211 is provided on the inner wall of the cleaning rod 21. The cleaning cavity 211 is connected to the interior of the replenishment cavity 25 through the tubular push rod 23. A cleaning hole 221 is provided on the inner wall of the cleaning groove 22, located at the gap between the bristles. The cleaning hole 221 is connected to the interior of the cleaning cavity 211.

[0046] Specific workflow: Based on the specific workflow in Example 1, when it is necessary to clean the outer surfaces of both sides of the oil tank 11, the telescopic device 24 is activated to drive the cleaning rod 21 through the push rod 23 to clean the outer surface of the oil tank 11. At the same time, the cleaning fluid is sent into the replenishment chamber 25. Then, because the end of the tubular push rod 23 slides into the replenishment chamber 25, the cleaning fluid can flow from the inside of the replenishment chamber 25 into the inside of the push rod 23. It flows along the inside of the push rod 23 and then flows through the cleaning hole 221 into the cleaning groove 22 between the cleaning rod 21 and the outer surface of the oil tank 11.

[0047] The cleaning fluid, sprayed from the cleaning hole 221, passes through the gaps in the cleaning brush bristles and impacts the outer surface of the oil tank 11. Combined with the scrubbing action of the cleaning brush bristles, this accelerates the removal of oil and impurities adhering to the surface of the oil tank 11. Because the cleaning rod 21 slides in contact with the outer surface of the oil tank 11, the contact points on both sides of the cleaning groove 22 intercept and limit the cleaning fluid in the middle, confining the cleaning fluid entering the cleaning groove 22. This causes the cleaning fluid inside the cleaning groove 22 to continuously accumulate, increasing the water pressure. The fluid then flows downwards along the cleaning groove 22 and exits from the bottom opening of the bottom recovery trough 121, which is reached by the cleaning rod 21. The automatic input and replenishment of the cleaning fluid further enhances the automation of cleaning the oil tank 11, reduces manual labor, and makes the cleaning operation more convenient and efficient.

[0048] Furthermore, in the hot summer environment, when the metal shell of the oil tank 11 gets too hot under long-term exposure to sunlight, the cleaning rod 21 can be activated to slide laterally and the cleaning fluid can be introduced, so that the cleaning fluid can be evenly coated on the outer surface of the oil tank 11, which can cool down the outer surface of the oil tank 11 and reduce the probability of the oil tank 11 causing an accident due to high temperature.

[0049] In the cleaning groove 22, which is the gap between the cleaning rod 21 and the outer surface of the oil tank 11, the flowing cleaning fluid accelerates under pressure. The friction and scrubbing action between the cleaning fluid and the outer surface of the oil tank 11 causes the oil stains and impurities adhering to the outer surface of the oil tank 11 to detach. They then mix into the flowing cleaning fluid and flow downward into the recovery tank 121 for collection, thereby improving the cleaning effect on the outer surface of the oil tank 11. When the oil tanker is in operation for a long time and it is difficult to replenish the cleaning fluid in time, the recovery tank 121 can be connected to the cleaning fluid tank through a pipeline, and an existing filter for oil stains and impurities can be installed in the middle of the pipeline to separate the oil stains and impurities in the cleaning fluid inside the recovery tank 121 before replenishing it into the cleaning fluid tank, forming a cycle of cleaning fluid, thereby reducing the frequency of replenishment and ensuring the continuous operation of the oil tanker.

[0050] Because during the cleaning process, the cleaning fluid and oily impurities are mainly confined to the cleaning tank 22 and concentrated on the outer surface of the oil tank 11. After cleaning, they flow down the cleaning tank 22 into the recovery tank 121, reducing the waste caused by the cleaning fluid spilling outwards and reducing the amount of oily impurities spilling into the surrounding environment with the cleaning fluid. This improves the utilization efficiency of the cleaning fluid, reduces waste, and also reduces the potential pollution to the surrounding environment during the cleaning process, making the cleaning operation of the oil tanker more in line with the theme of environmental protection.

[0051] Example 3:

[0052] Based on Embodiment 2, an inflation tube 231 is provided in the middle part of the push rod 23. The inflation tube 231 is connected to the inflation chamber 252 on one side of the supplementary chamber 25. The inflation tube 231 is a telescopic hose structure. A flushing tube 232 is provided at the part of the inflation tube 231 corresponding to the cleaning hole 221. The open end of the flushing tube 232 extends into the cleaning hole 221.

[0053] The cleaning hole 221 is a conical hole, with the small end located near the opening on the outer surface of the oil tank 11. The flushing pipe 232 has a conical pipe opening structure at the opening end, with the large end at the opening.

[0054] Specific workflow: Based on the specific workflow in Example 2, during the cleaning process, while the cleaning fluid is injected into the push rod 23 and enters the cleaning chamber 211, the air pump connected to the air chamber 252 is started to inject the purified airflow into the air chamber 252, which increases the air pressure inside the air chamber 252. Then, under the action of pressure difference, the airflow flows into the push rod 23 along the connected air pipe 231, and then flows out from the flushing pipe 232 on the side wall of the air pipe 231 pointing to the cleaning hole 221. The outflowing airflow mixes with the cleaning fluid to form a gas-liquid mixture, which increases the impact between the cleaning fluid inside the cleaning tank 22 and the outer surface of the oil tank 11.

[0055] The airflow exists in the form of bubbles in the cleaning fluid. The cleaning fluid mixed with bubbles is simultaneously subjected to the impact and agitation of the airflow, which increases the friction with the surface of the oil tank 11. Furthermore, when the bubbles in the cleaning fluid come into contact with the surface of the oil tank 11, they are impacted and broken. The impact of the broken bubbles is transmitted to the surface of the oil tank 11, further accelerating the removal of oil stains and impurities adhering to the surface of the oil tank 11.

[0056] Furthermore, as the airflow enters the cleaning tank 22 through the flushing pipe 232, the airflow tends to diffuse outward because the opening of the flushing pipe 232 in the middle of the cleaning hole 221 is a conical structure with the larger end of the opening. The cleaning hole 221 is also a conical structure with the smaller end of the opening, causing the cleaning fluid passing through the cleaning hole 221 to tend to concentrate. Thus, during the process of passing through the cleaning hole 221, the outwardly diffused airflow and the inwardly concentrated cleaning fluid come into contact and impact each other, promoting the mixing of the cleaning fluid and the airflow. This makes the airflow more evenly distributed in the cleaning fluid, thereby forming a gas-liquid mixture that participates in flushing and cleaning the outer surface of the oil tank 11, improving the cleaning effect on the outer surface of the oil tank 11.

[0057] Example 4:

[0058] Based on Embodiment 3, guide plates 26 are uniformly arranged on the inner wall of the cleaning tank 22 at the gap between the cleaning holes 221. The guide plates 26 are made of elastic material. One end of the guide plate 26 is elastically connected to the inner wall of the cleaning tank 22, and the other end of the guide plate 26 is inclined towards the recovery tank 121. The elastic connection here can be that the connection between the end of the guide plate 26 and the inner wall of the cleaning tank 22 is made of elastic material, or the end of the guide plate 26 and the inner wall of the cleaning tank 22 are rotatably connected, and a torsion spring is provided at the rotatable connection so that the guide plate 26 can return to its original position after swinging.

[0059] The guide plate 26 is close to the cleaning hole 221, and the opening of the cleaning hole 221 points towards the inclined surface of the guide plate 26; a breaking rod 261 is provided on the end of the guide plate 26, and the end of the breaking rod 261 near the outer surface of the oil tank 11 is a spherical structure; breaking spikes 262 are evenly provided on the side wall of the breaking rod 261, and the ends of the breaking spikes 262 are sharp.

[0060] Specific workflow: Based on the specific workflow in Example 3, as the cleaning rod 21 slides laterally back and forth, the cleaning hole 221 draws the cleaning fluid inside the cleaning chamber 211 into the cleaning groove 22 and sprays it into the cleaning groove 22. After acting on the outer surface of the oil tank 11, it carries away the oil and impurities and flows downward along the annular cleaning groove 22 and enters the recovery groove 121.

[0061] During this process, because the cleaning tank 22 is uniformly equipped with guide plates 26, when the downward-flowing cleaning fluid passes through the guide plates 26, it impacts the side surface of the guide plates 26 facing the direction of the cleaning fluid flow. At this time, the flow of the cleaning fluid is obstructed and flows along the inclined surface of the guide plates 26 to the narrow gap area between the end of the guide plates 26 and the outer surface of the oil tank 11, and passes through the gap area. The guiding effect of the guide plates 26 causes the cleaning fluid flowing inside the cleaning tank 22 to concentrate and flow to the gap area between the guide plates 26 and the outer surface of the oil tank 11. This causes the cleaning fluid to be pressurized during the concentrated passage through the gap area, which enhances the impact and friction on the outer surface of the oil tank 11, thereby strengthening the scouring and cleaning effect on the outer surface of the oil tank 11.

[0062] Furthermore, because the opening of the cleaning hole 221 near the guide plate 26 points to the surface of the guide plate 26 opposite to the direction of the cleaning fluid flow, the outflowing cleaning fluid impacts the back of the guide plate 26, causing the guide plate 26 to overcome the impact of the cleaning fluid flowing downward along the cleaning groove 22, swing back to its original position, and reduce the gap between the end of the guide plate 26 and the outer surface of the oil tank 11, prompting the cleaning fluid to be guided and concentrated to the gap area, further concentrating the flushing of the outer surface of the oil tank 11; the number of cleaning holes 221 is greater than that of the guide plate 26, and some are located in the gap area between adjacent guide plates 26, while some open towards the surface of the guide plate 26;

[0063] Furthermore, the downward-flowing cleaning fluid is blocked by the guide plate 26 and confined to the area between adjacent guide plates 26. In this area, the flow rate of the cleaning fluid slows down and is limited, thus increasing the pressure and the pressure on the outer surface of the oil tank 11 also increases. As the cleaning rod 21 moves, the cleaning fluid of the gas-liquid mixture in the area between adjacent guide plates 26, together with the brush bristles, enhances the frictional rinsing effect on the outer surface of the oil tank 11, further removing the tightly adhered oil stains and impurities on the outer surface of the oil tank 11.

[0064] The process of filling the cleaning fluid tank into the replenishment chamber 25 is carried out intermittently. When filling stops, the amount of cleaning fluid sprayed from the cleaning hole 221 decreases, and the restrictive effect on the guide plate 26 is reduced. Therefore, the guide plate 26 swings under the impact of the downward flow of the cleaning fluid, releasing the cleaning fluid in the area between adjacent guide plates 26, which accelerates the downward flow along the cleaning groove 22 and tangentially scours the outer surface of the oil tank 11, promptly removing the cleaned oil and impurities. Then the cleaning fluid is refilled, and this process is repeated, causing the flow rate of the cleaning fluid inside the cleaning groove 22 to change repeatedly and the vibration to intensify, which promotes the faster removal of oil and impurities adhering to the outer surface of the oil tank 11.

[0065] Furthermore, a breaking rod 261 is provided at the end of the guide plate 26. When the end of the guide plate 26 approaches the outer surface of the oil tank 11 and swings in contact, the end of the breaking rod 261 abuts against the outer surface of the oil tank 11, ensuring that the cleaning fluid can pass through the gap between the breaking rods 261 in the gap between the end of the guide plate 26 and the outer surface of the oil tank 11, thus avoiding excessive pressure in the gap area between the guide plates 26.

[0066] The guide plate 26 has uniformly arranged guide grooves 263 on the surface near the impact nozzle. The guide grooves 263 point towards the gap area between the breakers 261. This causes the cleaning fluid in contact with the guide plate 26 to flow along the guide grooves 263 to the gap area. While impacting the outer surface of the oil tank 11, the cleaning fluid also concentrates through the gap between the breakers 261 at the end of the guide plate 26 when passing through the gap area. Furthermore, the air bubbles mixed in the cleaning fluid come into contact with the breakers 262 on the outer surface of the breakers 261 when passing through the breakers 261. The sharp ends of the breakers 262 cause the air bubbles mixed in the cleaning fluid to break, and the impact of the broken air bubbles is concentrated in the gap area near the outer surface of the oil tank 11. This causes the oil stains and impurities that are more tightly adhered to the outer surface of the oil tank 11 to fall off and separate under the concentrated flushing action of the cleaning fluid.

[0067] Example 5:

[0068] Based on Embodiment 4, the inside of the guide plate 26 is hollow to form a combing cavity 264, and the inner wall of the guide groove 263 is provided with a liquid filling port 266. A filter screen is provided at the opening of the liquid filling port 266 to intercept impurities and dirt mixed in the cleaning fluid. The liquid filling port 266 is connected to the inside of the combing cavity 264.

[0069] The side wall of the combing chamber 264 is provided with a combing hole 265, and the opening of the combing hole 265 extends to the end of the shredder 262;

[0070] Specific workflow: Based on the specific workflow in Example 3, as the cleaning fluid filling process is carried out intermittently, the guide plate 26 swings back and forth in the cleaning tank 22. During this process, it contacts the bristles located in the gap area between the guide plates 26. The breaking rod 261 located at the end of the guide plate 26 is embedded in the gap area between the bristles. The breaking spike 262 end on the side wall of the breaking rod 261 is embedded in the bristle gap in the gap area of ​​the breaking rod 261. As the guide plate 26 swings, the breaking rod 261 and the breaking spike 262 end comb the bristles, remove the oil and impurities adhering to the bristle gap, reduce the situation of the bristles sticking to each other, and ensure that the bristles can properly clean the outer surface of the oil tank 11.

[0071] When the cleaning fluid flows along the guide channel 263, it contacts the filling port 266. A portion of the cleaning fluid enters the combing chamber 264 through the filling port 266 and flows along the inner wall of the combing chamber 264. The flow friction causes the elastic guide plate 26 to vibrate, improving the combing effect on the contact bristles. After the cleaning fluid flows into the combing chamber 264, it flows out from the communicating combing holes 265. Because the combing holes 265 are distributed on the ends of the shredders 262, the cleaning fluid sprayed from the opening of the combing holes 265 is directly injected into the bristle gaps along with the ends of the shredders 262, so that the bristles are cleaned from the inside out. Furthermore, the cleaning fluid flowing out of the opening of the combing holes 265 can directly act on the gap area of ​​the shredders 261, further clearing and cleaning the gap area of ​​the shredders 261, ensuring the cleanliness of the gaps of the shredders 261, thereby ensuring the combing effect of the shredders 261 and shredders 262 on the bristles.
