DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] As shown in the attached figure of the specification Figure 1-Figure 7 As shown, the present application proposes an oil tank truck that is easy to clean. The oil tank 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 to the frame at the rear side of the vehicle body 1 by bolt fixings or directly welded; an equipment platform 13 is provided on the top of the oil tank, and pipelines for oil outlet and oil inlet are provided on the equipment platform 13, as well as relevant monitoring equipment for monitoring data such as temperature and pressure inside the oil tank 11; and the support platform 12 and the equipment platform 13 respectively wrap the top and bottom of the oil tank 11, so that the arc outer surface of the oil tank 11 is directly exposed to the external environment as long as the parts close to the two sides, so fixed sleeves 2 are provided on the two side ends of the oil tank 11, and the fixed sleeve 2 is located between the support platform 12 and the equipment platform 13, and is fixed on the outer surface of the oil tank 11;

[0036] Arc-shaped cleaning rods 21 are slidably arranged on the outer surfaces of both sides of the oil tank 11, and cleaning grooves 22 are arranged on the side walls where the cleaning rods 21 contact the oil tank 11, and bristles are evenly arranged on the inner walls of the cleaning grooves 22; and the fixed sleeve 2 plays a role of wrapping and shielding the joints between the ends of both sides of the oil tank 11 and the side walls, and the outer surface of the side walls of the oil tank 11 is also shielded and protected by the cleaning rods 21, so that when external impact occurs, the fixed sleeve 2 and the cleaning rods 21 are limited to withstand the external impact, and play a role of dispersing support, reducing the direct impact on the oil tank 11 body, thereby reducing the probability of damage accidents to the oil tank 11;

[0037] A pushing rod 23 is arranged transversely through the cleaning rod 21, and the pushing 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 a controller inside the cab and is used to realize the lateral sliding of the cleaning rod 21; recovery grooves 121 are arranged on both sides of the support platform 12, and the bottom of the cleaning rod 21 slides and is embedded in the entrance of the recovery groove 121. A chamber structure is arranged at the bottom of the recovery groove 121, which can temporarily store the sewage mixed with oil generated during the cleaning operation. After arriving at a place where it can be treated, the sewage is pumped to the external sewage treatment facility through the bottom interface to avoid pollution of the surrounding environment.

[0038] Specific work flow: During the long-term operation of the oil tank, the outer surface of the oil tank 11 is directly exposed to the external environment. During the oil inlet and outlet process, the outer surface of the oil tank is adhered to oil stains. Due to the adhesion of the oil stains, external dust and impurities also adhere to the outer surface of the oil tank, forming dirt that adheres tightly to the outer surface of the oil tank. The dirt continues to adhere to the outer surface of the oil tank 11, which is easy to affect the appearance and sanitation of the outer surface of the oil tank, and is also easy to cause the outer surface of the oil tank 11 to be corroded more, 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, the present application automatically cleans the oil impurities adhered to the outer surface of the oil tank 11 through the cleaning rod 21, thereby ensuring that the outer surface of the oil tank 11 is fully cleaned; specifically, when cleaning is required, the driver can directly start the telescopic device 24 through the controller to drive the push rod 23 to drive the connected cleaning rods 21 to move laterally, and the lateral movement process is greater than the distance between adjacent cleaning rods 21, so that the outer surfaces of both sides of the oil tank 11 are fully covered;

[0040] During the movement of the cleaning rod 21, the driver sprays cleaning liquid on the outer surface of the oil tank 11 in advance, and the sliding cleaning rod 21 scrapes the outer surface of the oil tank 11, so that the oil impurities adhering to the outer surface of the oil tank 11 are accelerated to separate and flow downward along the outer surface of the oil tank 11 with the cleaning liquid; the cleaning liquid is a special detergent used for cleaning oil in the prior art, which is mixed with clean water and stored in the cleaning liquid tank inside the support platform 12 in advance;

[0041] At the same time, the bristles evenly distributed on the inner wall of the cleaning groove 22 sweep the oily impurities adhered to the outer surface of the oil tank 11, and cooperate with the cleaning liquid flowing from top to bottom to accelerate the separation of the oily impurities adhered to the surface of the oil tank 11 and mix them into the cleaning liquid, and then flow downward along the cleaning rod 21 and the outer surface of the oil tank 11 into the recovery groove 121 of the bottom support platform 12, so as to facilitate the subsequent recovery and purification of the sewage mixed with the oily impurities, and avoid the cleaning liquid mixed with oily impurities flowing around during the cleaning process, causing pollution to the surrounding environment; such an automatic cleaning method does not require the driver to drive the tanker into a special cleaning place for manual flushing and cleaning during the cleaning process. The present application can select a nearby parking location for cleaning when cleaning is needed, and the cleaned sewage can be recycled and stored, reducing waste on the surrounding environment;

[0042] In addition, compared with the manual flushing method directly using a handheld nozzle, the present application is more automated by pushing the cleaning rod 21 to achieve full coverage of scraping and scrubbing, and the cleaning effect more comprehensively covers the surfaces on both sides of the oil tank 11, reducing the situation where oil stains and impurities in local areas are manually omitted during the cleaning process. While reducing labor input, it ensures that the outer surface of the oil tank 11 is fully cleaned, thereby ensuring the service life of the oil tank 11.

[0043] Embodiment 2:

[0044] On the basis of the first embodiment, regarding the use of the cleaning liquid, in addition to the prior art using a water gun for direct spraying, or using a brush or other tools for smearing, this embodiment provides a more efficient use method, wherein the telescopic device 24 is arranged on the fixed sleeve 2 on the side close to the rear of the vehicle body 1, and a replenishing chamber 25 is arranged inside the fixed sleeve 2 on the side close to the head of the vehicle body 1, and the replenishing chamber 25 is communicated with the cleaning liquid tank inside the support platform 12, and the cleaning liquid tank is filled with cleaning liquid and communicated with the replenishing chamber 25 through a pipeline, and a water pump device is arranged in the middle of the pipeline, and the cleaning liquid is pumped into the replenishing chamber 25 through the pipeline during the cleaning operation to perform the cleaning operation;

[0045] A replenishing hole 251 is provided on the side wall of the replenishing chamber 25 at a position directly facing the push rod 23, and the end of the push rod 23 slides through the replenishing hole 251 and is embedded in the replenishing chamber 25, and during the lateral reciprocating movement of the push rod 23, the end of the push rod 23 remains inside the replenishing chamber 25 and does not collide with the inner wall of the replenishing chamber 25; a cleaning chamber 211 is provided on the inner wall of the cleaning rod 21, and the cleaning chamber 211 is communicated with the inside of the replenishing chamber 25 through the push rod 23 of the tubular structure; a cleaning hole 221 is provided on the inner wall of the cleaning groove 22 at a position located in the gap between the bristles, and the cleaning hole 221 is communicated with the inside of the cleaning chamber 211;

[0046] Specific workflow: Based on the specific workflow in the first embodiment, when it is necessary to clean the outer surfaces of both sides of the oil tank 11, the telescopic device 24 is started to drive the cleaning rod 21 to brush and clean the outer surface of the oil tank 11 through the push rod 23, and the cleaning liquid is sent into the replenishing chamber 25. Then, because the end of the push rod 23 of the tubular structure slides and extends into the replenishing chamber 25, the cleaning liquid can flow from the replenishing chamber 25 into the push rod 23, flow along the inside of the push rod 23, and then flow into the cleaning groove 22 between the cleaning rod 21 and the outer surface of the oil tank 11 through the cleaning hole 221;

[0047] After the cleaning liquid is sprayed out of the cleaning hole 221 and passes through the gap between the cleaning bristles to impact the outer surface of the oil tank 11, the cleaning action of the cleaning bristles accelerates the cleaning of the oil dirt and impurities adhered to the surface of the oil tank 11; because the cleaning rod 21 is in sliding contact with the outer surface of the oil tank 11, the contact of the parts of the cleaning rod 21 located on both sides of the cleaning groove 22 has an intercepting and limiting effect on the cleaning liquid in the middle, so that the cleaning liquid entering the cleaning groove 22 is restricted to the cleaning groove 22, so that the cleaning liquid inside the cleaning groove 22 continues to accumulate and the water pressure increases, and then flows along the downward extension direction of the cleaning groove 22, and flows out from the bottom opening of the cleaning groove 22 where the cleaning rod 21 extends into the bottom recovery groove 121; the automatic input and replenishment of the cleaning liquid further improves the automation of the cleaning of the oil tank 11, reduces the manual input, and makes the cleaning operation more convenient and efficient;

[0048] In addition, in a hot summer environment, when the metal shell of the oil tank 11 is too hot under long-term exposure to sunlight, the cleaning rod 21 can be started to slide horizontally and the cleaning liquid can be introduced so that the cleaning liquid is evenly applied to the outer surface of the oil tank 11, thereby cooling the outer surface of the oil tank 11 and reducing the probability of accidents caused by high temperature in the oil tank 11.

[0049] In the cleaning groove 22 in the gap between the cleaning rod 21 and the outer surface of the oil tank 11, the flowing cleaning liquid is accelerated under the action of pressure, and the friction and scrubbing effect between the cleaning liquid and the outer surface of the oil tank 11 causes the oil impurities adhering to the outer surface of the oil tank 11 to separate, and then mix into the flowing cleaning liquid, and enter the recovery groove 121 downward to be collected, thereby improving the cleaning effect of the outer surface of the oil tank 11; when the oil tanker is in a working state for a long time and it is difficult to replenish the cleaning liquid in time, the recovery groove 121 can be connected with the cleaning liquid tank through a pipeline, and an existing filter for oil impurities can be set in the middle of the pipeline, and the oil impurities in the cleaning liquid inside the recovery groove 121 can be separated and then replenished into the cleaning liquid tank, so as to form a recycling use of the cleaning liquid, thereby reducing the frequency of replenishment and ensuring the continuous operation of the oil tanker;

[0050] Because during the cleaning process, the cleaning liquid and oil impurities are mainly confined to the cleaning tank 22 and concentrated on the outer surface of the oil tank 11, and after cleaning, they flow downward along the cleaning tank 22 to the recovery tank 121, thereby reducing the waste caused by the cleaning liquid spilling outward, and reducing the oil impurities spilling into the surrounding environment of the oil tank along with the cleaning liquid, thereby improving the utilization efficiency of the cleaning liquid and reducing waste, and also reducing the pollution to the surrounding environment that may occur during the cleaning process, making the cleaning operation of the tanker truck more in line with the theme of environmental protection.

[0051] Embodiment three:

[0052] On the basis of the second embodiment, an air filling tube 231 is provided in the middle part of the push rod 23, and the air filling tube 231 is communicated with the air filling chamber 252 on one side of the supplementary chamber 25, and the air filling tube 231 is a telescopic hose structure, and a flushing tube 232 is provided at the position of the air filling tube 231 corresponding to the cleaning hole 221, and the open end of the flushing tube 232 extends into the cleaning hole 221;

[0053] The cleaning hole 221 is a tapered hole, and the small end is located at an opening position close to the outer surface of the oil tank 11. The open end of the flushing pipe 232 is a tapered pipe mouth structure, and the opening is the large end.

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

[0055] The airflow exists in the cleaning liquid in the form of bubbles. The cleaning liquid mixed with bubbles is impacted and stirred by the airflow at the same time, and the friction with the surface of the oil tank 11 is increased. The bubbles in the cleaning liquid are impacted and broken when they come into contact with the surface of the oil tank 11. The impact of the bubble breaking is transmitted to the surface of the oil tank 11, further accelerating the shedding of oil impurities adhering to the surface of the oil tank 11.

[0056] Furthermore, when the airflow enters the cleaning tank 22 through the flushing tube 232, because the opening of the flushing tube 232 located in the middle of the cleaning hole 221 is a conical structure, and the opening is the large end, the outflowing airflow tends to diffuse outward, and the cleaning hole 221 is also a conical structure with a small end, so that the cleaning liquid passing through the cleaning hole 221 tends to be concentrated; in this way, in the process of passing through the cleaning hole 221, the airflow diffusing outward and the cleaning liquid concentrating inward contact and impact each other, which promotes the mixing of the cleaning liquid and the airflow, so that the airflow is more evenly distributed in the cleaning liquid, thereby forming a gas-liquid mixture to participate in the flushing and cleaning of the outer surface of the oil tank 11, thereby improving the cleaning effect of the outer surface of the oil tank 11.

[0057] Embodiment 4:

[0058] On the basis of the third embodiment, guide plates 26 are evenly arranged at the positions of the gaps between the cleaning holes 221 on the inner wall of the cleaning groove 22, and 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 groove 22, and the other end of the guide plate 26 is inclined toward the direction close to the recovery groove 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 groove 22 is made of elastic material, or the end of the guide plate 26 and the inner wall of the cleaning groove 22 are rotatably connected, and a torsion spring is arranged at the rotatable connection, so that the guide plate 26 can be reset after swinging;

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

[0060] Specific working process: Based on the specific working process in the third embodiment, as the cleaning rod 21 slides back and forth horizontally, the cleaning hole 221 draws the cleaning liquid inside the cleaning chamber 211 and sprays it into the cleaning groove 22. After acting on the outer surface of the oil tank 11, the cleaning liquid takes away the oil impurities and flows downward along the annular cleaning groove 22 and enters the recovery groove 121.

[0061] In this process, because the guide plates 26 are evenly arranged inside the cleaning groove 22, when the cleaning liquid flowing downward passes through the guide plates 26, it impacts the side surface of the guide plates 26 facing the flow direction of the cleaning liquid. At this time, the flow of the cleaning liquid is blocked 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 liquid flowing inside the cleaning groove 22 to flow concentratedly to the gap area between the guide plates 26 and the outer surface of the oil tank 11, so that the cleaning liquid is pressurized in the process of concentratedly passing through the gap area, and the impact and friction effect on the outer surface of the oil tank 11 is enhanced, thereby enhancing the flushing and cleaning effect on the outer surface of the oil tank 11;

[0062] And because the opening of the cleaning hole 221 near the guide plate 26 points to the surface of the guide plate 26 facing away from the flow direction of the cleaning liquid, the outflowing cleaning liquid impacts the back of the guide plate 26, so that the guide plate 26 overcomes the impact of the cleaning liquid flowing downward along the cleaning groove 22, swings back, and the distance between the end of the guide plate 26 and the outer surface of the oil tank 11 is reduced, so that the cleaning liquid is guided to flow to the gap area, and further concentratedly flushes the outer surface of the oil tank 11; the number of cleaning holes 221 is greater than that of the guide plates 26, and some of them are located in the gap area between adjacent guide plates 26, and some of them open to the surface of the guide plate 26;

[0063] Furthermore, the cleaning liquid flowing downward is intercepted by the guide plates 26 and is limited to the area between the adjacent guide plates 26. In this area, the flow rate of the cleaning liquid is slowed down and limited, so the pressure increases, and the pressure on the outer surface of the oil tank 11 also increases. As the cleaning rod 21 moves, the cleaning liquid of the gas-liquid mixture in the area between the adjacent guide plates 26 cooperates with the brush bristles to enhance the friction flushing effect on the outer surface of the oil tank 11, further removing the oil impurities that are more tightly adhered to the outer surface of the oil tank 11.

[0064] The process of controlling the cleaning liquid tank to fill the replenishing chamber 25 is performed intermittently. When the filling is stopped, the cleaning liquid sprayed out of the cleaning hole 221 is reduced, and the restrictive effect on the guide plate 26 is reduced. Therefore, the guide plate 26 swings under the impact of the cleaning liquid flowing downward, releasing the cleaning liquid in the area between the adjacent guide plates 26, so that it accelerates to flow downward along the cleaning groove 22, tangentially flushes the outer surface of the oil tank 11, and promptly takes away the cleaned oil impurities; then the cleaning liquid is resumed to be filled, and this reciprocating process causes the flow rate of the cleaning liquid in the cleaning groove 22 to change back and forth, and the vibration is intensified, which accelerates the separation of the oil impurities adhering to the outer surface of the oil tank 11;

[0065] Furthermore, a breaker bar 261 is provided at the end of the guide plate 26. When the end of the guide plate 26 is swung toward the outer surface of the oil tank 11, the end of the breaker bar 261 abuts against the outer surface of the oil tank 11, ensuring that the cleaning liquid can pass through the gap between the breaker bar 261 in the gap between the end of the guide plate 26 and the outer surface of the oil tank 11, thereby avoiding excessive pressure in the gap area between the guide plates 26.

[0066] The guide plate 26 is evenly provided with guide grooves 263 on the surface of one side close to the impact nozzle, and the guide grooves 263 point to the gap area between the breaking rods 261, so that the cleaning liquid contacting the guide plate 26 is concentrated along the guide grooves 263 to flow to the gap area, and impacts the outer surface of the oil tank 11. At the same time, the cleaning liquid is concentrated to pass through the gap between the breaking rods 261 at the end of the guide plate 26 when passing through the gap area, and the bubbles mixed in the cleaning liquid contact the breaking thorns 262 on the outer surface of the breaking rod 261 when passing through the breaking rod 261. The sharp ends of the breaking thorns 262 break the bubbles mixed in the cleaning liquid, and the bubble breaking impact is concentrated to the gap area close to the outer surface of the oil tank 11, so that the oil impurities that are more tightly adhered to the outer surface of the oil tank 11 are also dropped and separated under the concentrated flushing action of the cleaning liquid.

[0067] Embodiment five:

[0068] On the basis of the fourth embodiment, the guide plate 26 is hollow inside to form a combing chamber 264, the inner wall of the guide groove 263 is provided with a liquid filling port 266, and a filter is provided at the opening of the liquid filling port 266 to intercept impurities and dirt mixed in the inflowing cleaning liquid, and the liquid filling port 266 is communicated with the inside of the combing chamber 264;

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

[0070] Specific working process: On the basis of the specific working process in Example 3, as the cleaning liquid filling process is carried out intermittently, the guide plate 26 swings back and forth in the cleaning groove 22, and in this process contacts the bristles located in the gap area between the guide plates 26, and the breaking rod 261 located at the end of the guide plate 26 is embedded in the gap area between the bristles, and the end of the breaking thorn 262 on the side wall of the breaking rod 261 is embedded in the gap between the bristles in the gap area of ​​the breaking rod 261. As the guide plate 26 swings, the breaking rod 261 and the end of the breaking thorn 262 play a combing role on the bristles, remove the oil impurities adhered to the gap between the bristles, reduce the adhesion between the bristles, and ensure that the bristles normally brush the outer surface of the oil tank 11;

[0071] When the cleaning liquid flows along the guide groove 263, it contacts the filling port 266. A part of the cleaning liquid 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, thereby improving the combing effect on the contacted bristles. After the cleaning liquid flows into the combing chamber 264, it flows out from the interconnected combing holes 265. Because the combing holes 265 are distributed on the ends of the crushing thorns 262, the cleaning liquid sprayed from the opening of the combing hole 265 is directly injected into the gap between the bristles along the ends of the crushing thorns 262, so that the bristles are cleaned from the inside to the outside, and the cleaning liquid flowing out of the opening of the combing hole 265 can directly act on the gap area of ​​the crushing rod 261, continue to dredge and clean the gap area of ​​the crushing rod 261, ensure the cleanliness of the gap of the crushing rod 261, thereby ensuring the combing effect of the crushing rod 261 and the crushing thorns 262 on the bristles.
