[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0030] like Figure 1-7 As shown, the utility model provides a drainage pipe maintainer, including a crawler vehicle 1, a liquid storage tank 3 for storing a dissolving liquid is fixedly provided at the top of the crawler vehicle 1, a controller 2 is fixedly provided at the outer end of the liquid storage tank 3, the crawler vehicle 1 is arranged at the output end of the controller 2, a spraying component 5 for spraying the dissolving liquid is provided at the front side of the liquid storage tank 3, and a cleaning component 8 capable of cleaning oil stains is provided at the rear side of the liquid storage tank 3;

[0031] Two electric push rods 6 are provided at the top of the liquid storage tank 3, and the rear ends of the electric push rods 6 extend to the rear side of the liquid storage tank 3 and are connected to the cleaning assembly 8. The electric push rods 6 are arranged at the output end of the controller 2, and two supporting assemblies 7 are provided at the rear side of the liquid storage tank 3, and the supporting assemblies 7 are connected to the electric push rods 6 and move synchronously with the electric push rods 6;

[0032] The support assembly 7 includes a bracket 701, and two rollers 705 are provided on the inner wall of the bracket 701 through a rotating shaft. The rollers 705 can contact the inner wall of the drainage pipe, and one of the rollers 705 is provided with a speed sensor 706 fixed at the outer end of the bracket 701, and the speed sensor 706 is arranged at the input end of the controller 2.

[0033] The maintainer is driven by the tracked vehicle 1 to move inside the drainage pipe as a whole. During the movement, the spraying component 5 sprays the dissolving liquid inside the liquid storage tank 3 onto the inner wall of the pipe, and the cleaning component 8 cleans the dissolved oil on the inner wall of the pipe. During the movement of the tracked vehicle 1, the roller 705 rolls on the pipe wall as the tracked vehicle 1 moves. The faster the tracked vehicle 1 moves, the faster the rotation speed of the roller 705. The rotation speed sensor 706 senses the rotation speed of the roller 705 and controls the electric push rod 6 through the controller 2 according to the rotation speed. The faster the rotation speed, the longer the electric push rod 6 will extend backward, and the larger the distance between the cleaning component 8 and the spraying component 5. Therefore, the faster the moving speed of the maintainer, the larger the distance between the cleaning component 8 and the spraying component 5. The dissolution time of the oil is increased by increasing the distance between the cleaning component 8 and the spraying component 5, and the shortened dissolution time of the oil due to the increase in the moving speed is compensated. Under the premise of not affecting the maintenance efficiency, the dissolution time of the oil is increased as much as possible, so that the cleaning of the oil is more sufficient.

[0034] In order to make the roller 705 fully contact with the inner wall of the pipe, Figure 1 , 5 As shown in FIG. 6 , the two electric push rods 6 are fixedly connected by a transverse plate, and the two support assemblies 7 are symmetrically distributed on the upper and lower sides of the transverse plate. The support assembly 7 also includes a sleeve 702 fixedly arranged on the side of the bracket 701 facing the transverse plate;

[0035] A spring 704 is fixedly disposed on the inner wall of the sleeve 702, and a guide rod 703 is fixedly disposed at one end of the spring 704. The guide rod 703 extends toward one end of the horizontal plate to the outside of the sleeve 702 and is fixedly connected to the horizontal plate.

[0036] A sliding seat is fixed at the front end of the electric push rod 6, and two columns are fixed at the top of the liquid storage tank 3. The tops of the two columns respectively penetrate the two sliding seats and are fixed with limit plates. The height of the electric push rod 6 can also be adjusted under the action of the support assembly 7.

[0037] When the maintainer is placed in the drainage pipe, the elastic force of the spring 704 will push the sleeve 702 and the bracket 701, and make the roller 705 automatically contact the inner wall of the pipe, and the support component 7 can adapt to drainage pipes with different inner diameters. In this process, the height of the electric push rod 6 also slides under the action of the support component 7, and the slide seat slides on the column.

[0038] In order to remotely control the maintainer, Figure 1 , 4 As shown in 7, an antenna, an air filling pipe and a water injection pipe are fixedly provided at the top of the liquid storage tank 3. A sealing plug is provided at the open end of the water injection pipe. The dissolved liquid is added into the liquid storage tank 3 through the water injection pipe. An air pump 4 is fixedly provided on the air filling pipe. The air pressure inside the liquid storage tank 3 is increased through the air pump 4 and the air filling pipe, and the dissolved liquid inside the liquid storage tank 3 is driven to flow outward by squeezing.

[0039] The antenna is arranged at the input end of the controller 2 , and the air pump 4 is arranged at the output end of the controller 2 .

[0040] The spray assembly 5 includes a connecting pipe 502 fixedly arranged at the front side of the liquid storage tank 3 , a diverter tube 501 is fixedly arranged at the front end of the connecting pipe 502 , and a plurality of nozzles 503 are fixedly arranged at the outer end of the diverter tube 501 .

[0041] The maintainer can be remotely controlled to move inside the drainage pipe through the antenna. When the dissolving liquid needs to be sprayed, the air pump 4 drives the air into the liquid storage tank 3, and the dissolving liquid is squeezed into the diversion cylinder 501 through the connecting pipe 502 by air pressure, and sprayed to the surroundings through the nozzle 503, so that the dissolving liquid contacts the inner wall of the drainage pipe and dissolves the oil stains on the pipe wall.

[0042] After the oil is dissolved, it needs to be cleaned up. Figure 1, 2 As shown, the cleaning assembly 8 includes a fixed head 801, and a plurality of sliding plates 803 are provided at the outer end of the fixed head 801. Two clamping plates 802 are provided at one end of the sliding plate 803 facing the fixed head 801 through a slide rail. The position of the sliding plate 803 can be adjusted by sliding. The clamping plate 802 is fixed at the outer end of the fixed head 801, and the sliding plate 803 is clamped between the corresponding two clamping plates 802. The clamping plate 802 is provided with a fastening bolt through a thread.

[0043] The sliding plate 803 has a fixed plate 804 at one end away from the fixed head 801, a part of the fixed plate 804 has a brush 805 at one end away from the sliding plate 803, and the other fixed plate 804 has a rubber scraper 806 at one end away from the sliding plate 803. The brush 805 and the rubber scraper 806 can clean the oil stains on the inner wall of the drainage pipe.

[0044] When cleaning oil stains, the fixed head 801 rotates and drives the fixed plate 804 connected to its outer end to rotate. The bristles 805 on the fixed plate 804 come into contact with the pipe wall to scrape the decomposed oil stains on the pipe wall. The bristles 805 rub against the pipe wall to play a scrubbing role. Before maintaining the drainage pipe, the sliding plate 803 can be slid according to the size of the pipe, and the distance between the fixed plate 804 and the fixed head 801 can be adjusted so that the bristles 805 and the rubber scraper 806 can come into contact with the pipe wall.

[0045] In order to drive the cleaning assembly 8 to rotate, as Figure 1 , 2 As shown in , 3 and 7, a protective tube 9 is provided at the front side of the fixed head 801, the rear end of the electric push rod 6 is fixedly connected to the outer end of the protective tube 9, and a detachable end cover 10 is provided at the front end of the protective tube 9;

[0046] A motor 11 is fixedly mounted on the inner wall of the protection tube 9 . The motor 11 is disposed at the output end of the controller 2 . The output shaft of the motor 11 extends to the rear side of the protection tube 9 and is fixedly connected to the fixing head 801 .

[0047] The two support components 7 symmetrically distributed up and down play a supporting role, so that the electric push rod 6 and the cleaning component 8 are both located in the center of the pipe, so that the cleaning component 8 can clean the inner wall of the drainage pipe, and the motor 11 inside the protective tube 9 directly drives the fixed head 801 to rotate and makes the cleaning component 8 rotate as a whole. The outer end of the protective tube 9 is connected to the rear end of the electric push rod 6, so the extension and retraction of the electric push rod 6 can control the front and rear distance of the cleaning component 8.

[0048] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
