Description

Technical Field

[0001] This utility model belongs to the field of coating technology, and in particular relates to a spraying device for internal drag-reducing coatings. Background Technology

[0002] In modern industrial sectors such as oil, natural gas, and chemicals, pipeline transportation is an extremely important method of material transport. In order to reduce resistance during pipeline transportation, improve transportation efficiency, and reduce energy consumption, the application of internal drag-reducing coatings is becoming increasingly widespread. Internal drag-reducing coatings can form a smooth coating on the inner wall of the pipeline, effectively reducing the friction between the fluid and the inner wall of the pipeline, thereby achieving more efficient material transportation.

[0003] However, existing internal drag-reducing coating spraying devices are not convenient for cleaning the inner wall of the pipe during use. When spraying on a contaminated inner wall, the coating cannot fully and tightly bond with the pipe surface, resulting in reduced coating adhesion and problems such as bubbles and peeling, which greatly affects the spraying effect and coating quality. Utility Model Content

[0004] The purpose of this invention is to provide a spraying device for internal drag-reducing coatings. By setting up a cleaning mechanism, it solves the problem that it is inconvenient to clean the inner wall of the pipe. When spraying, the coating cannot fully and tightly bond with the pipe surface when the inner wall of the pipe is contaminated, resulting in a decrease in coating adhesion and problems such as bubbles and peeling, which greatly affect the spraying effect and coating quality.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a spraying device for internal drag-reducing coating, including a housing, on which a cleaning mechanism and several adjustment mechanisms are provided;

[0007] The bottom of the housing is fixedly connected to wheels, and the back of the housing is provided with a spray pipe. The cleaning mechanism includes a worm gear that rotates inside the inner wall of the housing. The back of the worm gear extends to the outside of the housing. A gear is fixedly connected to the back of the worm gear. The back of the gear is fixedly connected to the spray pipe. An internal gear is rotatably connected to the back of the housing. The gear meshes with the internal gear. A hollow rod is provided inside the housing.

[0008] Furthermore, a worm gear is fixedly connected to the outer wall of the hollow rod one, the worm gear meshes with the worm, and two connecting rods two are slidably connected to the inner wall of the hollow rod one.

[0009] Furthermore, a spring is fixedly connected between the two connecting rods 2, and a transmission wheel is fixedly connected to the side of the two connecting rods 2 that is far apart from each other.

[0010] Furthermore, the back of the housing is provided with several cleaning plates, and a motor is fixedly connected to the inner wall of the housing. The output shaft of the motor is fixedly connected to a worm gear through a coupling.

[0011] Furthermore, the adjustment mechanism includes a hollow rod two fixed to the outer wall of the internal gear, and a connecting rod is slidably connected to the inner wall of the hollow rod two, and the connecting rod is fixedly connected to the cleaning plate.

[0012] Furthermore, the connecting rod is provided with several limiting holes, and a sliding rod is slidably connected to the hollow rod 2, with the front of the sliding rod extending into the limiting holes.

[0013] Furthermore, a handle is fixedly connected to the back of the slide rod, and a second spring is sleeved on the outer wall of the slide rod. The front of the second spring is fixedly connected to the hollow rod, and the back of the second spring is fixedly connected to the handle.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a cleaning mechanism, after adjustment, the motor is started. When the motor rotates, the worm gear rotates accordingly. As the worm gear rotates, the gear also rotates, causing the internal gear to rotate. The rotation of the internal gear, through the hollow rod 2 and connecting rod, causes the cleaning plate to rotate simultaneously. The rotation of the cleaning plate cleans the inner wall of the pipe, thus achieving the effect of cleaning the pipe. Simultaneously, when the worm gear rotates, the worm wheel also rotates. When the worm wheel rotates, the hollow rod 1 also rotates. The rotation of the hollow rod 1 causes the connecting rod 2 to rotate. At this time, the spring 1 inside the hollow rod 1 pushes the two connecting rods 2 outwards, causing the transmission wheel on the connecting rod 2 to connect with the pipe... When the connecting rod rotates, the transmission wheel also rotates. At this time, the transmission wheel in contact with the inner wall of the pipe will move the entire device forward. As the device moves, the wheel will also move, achieving the effect of cleaning the entire pipe. When the gear rotates, the nozzle will also rotate, and the spraying will be started. As the device moves forward, the nozzle will continuously spray the inside of the pipe. This ensures that after the cleaning plate has finished cleaning the inner wall of the pipe, the nozzle will immediately spray, reducing the possibility of the cleaned inner wall of the pipe being exposed to the environment again and being contaminated. It can ensure that the paint is sprayed on the clean pipe surface in a timely manner, which is conducive to obtaining better spraying effect and coating quality.

[0016] 2. By setting an adjustment mechanism, the cleaning plate is adjusted to fit the inner wall of the pipe according to the required pipe size. Pulling the handle causes the spring to be pulled as it slides on the hollow rod. With continued pulling, the handle slides out of the limiting hole, stopping the limiting effect on the sliding rod. The length of the connecting rod extending beyond the hollow rod is then adjusted, changing the distance of the cleaning plate. After adjusting to the appropriate length, releasing the handle causes the handle to be pulled by the spring. As the handle is pulled, the sliding rod slides back into the corresponding limiting hole. This achieves the effect of adjusting the length of the cleaning plate to adapt to the pipe size, allowing for flexible adjustment of the cleaning plate length according to different pipe sizes, ensuring a tight fit with the inner wall of the pipe, guaranteeing the comprehensiveness and effectiveness of the cleaning work, meeting diverse pipe cleaning needs, and expanding the applicability of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a spraying device for internal drag-reducing coatings, including a housing 1. The housing 1 is equipped with a cleaning mechanism 2 and several adjusting mechanisms 3. A wheel 101 is fixedly connected to the bottom of the housing 1, and a spray pipe 102 is provided on the back of the housing 1. The cleaning mechanism 2 includes a worm gear 211 that rotates inside the inner wall of the housing 1. The back of the worm gear 211 extends outside the housing 1, and a gear 212 is fixedly connected to the back of the worm gear 211. The back of the gear 212 is fixedly connected to the spray pipe 102. An internal gear 213 is rotatably connected to the back of the housing 1, and the gear 212 meshes with the internal gear 213. A hollow rod 214 is provided inside the housing 1, and a worm wheel 215 is fixedly connected to the outer wall of the hollow rod 214. The worm wheel 215 meshes with the worm gear 211. The inner wall of the hollow rod 214 is slidably connected to two connecting rods 216. A spring 217 is fixedly connected between the two connecting rods 216. A transmission wheel 218 is fixedly connected to the side of the two connecting rods 216 that are far apart from each other. Several cleaning plates 219 are provided on the back of the sleeve 1. A motor 2110 is fixedly connected to the inner wall of the sleeve 1. The output shaft of the motor 2110 is fixedly connected to the worm gear 211 through a coupling. By setting up the cleaning mechanism 2, the spray nozzle is immediately sprayed after the cleaning plates have cleaned the inner wall of the pipe. This reduces the possibility of the cleaned inner wall of the pipe being exposed to the environment again and being contaminated. It can ensure that the paint is sprayed on the clean pipe surface in a timely manner, which is conducive to obtaining better spraying effect and coating quality.

[0028] The adjustment mechanism 3 includes a hollow rod 311 fixed to the outer wall of the internal gear 213. A connecting rod 312 is slidably connected to the inner wall of the hollow rod 311. The connecting rod 312 is fixedly connected to the cleaning plate 219. Several limiting holes 313 are provided on the connecting rod 312. A sliding rod 314 is slidably connected to the hollow rod 311. The front of the sliding rod 314 extends into the limiting holes 313. A handle 315 is fixedly connected to the back of the sliding rod 314. A spring 316 is sleeved on the outer wall of the sliding rod 314. The front of the spring 316 is fixedly connected to the hollow rod 311. The back of the spring 316 is fixedly connected to the handle 315. By setting the adjustment mechanism 3, the length of the cleaning plate can be flexibly adjusted according to the pipe of different sizes, so that it fits tightly against the inner wall of the pipe, ensuring the comprehensiveness and effectiveness of the cleaning work, meeting diverse pipe cleaning needs, and expanding the applicability of the device.

[0029] One specific application of this embodiment is as follows: In use, first place the device in the appropriate position. Then, adjust the cleaning plate 219 to fit against the inner wall of the pipe according to the required pipe size. At this time, pull the handle 315. When the handle 315 slides on the hollow rod 311, the spring 316 will be pulled. With continued pulling of the handle 315, the handle 315 will slide out of the limiting hole 313. At this time, the sliding rod 314 will stop its restrictive effect. Then, adjust the length of the connecting rod 312 extending beyond the hollow rod 311. The distance of the cleaning plate 219 can be changed by adjusting it. After adjusting to the appropriate length, the pull on the handle 315 is released. At this time, the handle 315 will be pulled by the spring 316. When the handle 315 is pulled, the slide rod 314 will slide accordingly. At this time, the slide rod 314 will slide back into the corresponding limiting hole 313. This achieves the effect of adjusting the length of the cleaning plate 219 to adapt to the pipe size. After the adjustment is completed, the motor 2110 is started. When the motor 2110 rotates, the worm gear 211 rotates accordingly. When the worm gear 211 rotates, the gear 212... The internal gear 213 will also rotate as the gear 212 rotates, causing the internal gear 213 to rotate as well. The rotation of the internal gear 213, in turn, will cause the cleaning plate 219 to rotate simultaneously via the hollow rod 211 and connecting rod 312. The rotation of the cleaning plate 219 will clean the inner wall of the pipe, thus achieving the effect of cleaning the pipe. Simultaneously, the worm gear 215 will also rotate as the worm 211 rotates, and the hollow rod 214 will also rotate as the worm gear 215 rotates. The rotation of the hollow rod 214 will cause the connecting rod 216 to rotate as well. At this time, the internal gear 214... Spring 217 pushes the two connecting rods 216 outward, causing the transmission wheel 218 on the connecting rod 216 to contact the pipe. When the connecting rod 216 rotates, the transmission wheel 218 also rotates. At this time, the transmission wheel 218, which is in contact with the inner wall of the pipe, will move the entire device forward. When the device moves, the wheel 101 will also move, achieving the effect of cleaning the entire pipe. When the gear 212 rotates, the spray nozzle 102 will also rotate, and the spraying will be started. As the device moves forward, the spray nozzle 102 will continuously spray the inside of the pipe.
