However, the lubricating oil is difficult to be recycled immediately after use, and there is a certain waste of lubricating oil materials. In addition, the application of lubricating oil and pushing the instrument are carried out separately, and the steps are too troublesome. Therefore, a leakage detection device for urban water supply pipeline network is proposed to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figure 1-5As shown, a leakage detection device for a city water supply pipe network comprises a detector body 1; a plurality of groups of rotating wheels 11 are rotatably connected at the bottom of the detector body 1; a first connecting frame 12 is fixedly connected to the top of the detector body 1; a scraper 13 is fixedly connected to the end of the first connecting frame 12, and the inner wall of the scraper 13 is inclined; a storage box 14 is fixedly connected to the end of the scraper 13; a pump body 15 is installed on the inner wall of the storage box 14; a pipe body 16 is fixedly connected to the top of the pump body 15, and the pipe body 16 and the pump body 15 are connected; when working, the staff needs to connect the detector body 1 and the display device together with the help of a connecting line, and then place the detector body 1 on the pipeline so that the rotating wheel 11 is in direct contact with the pipeline, and by arranging the scraper 13 in the middle of the detector body 1, the staff can first add to the inner walls of the two groups of storage boxes 14 when pushing the detector body 1 An appropriate amount of lubricating oil is added, and then the two sets of pump body 15 switches are started, and the lubricating oil is evenly sprayed out in conjunction with the tube body 16 and the multiple sets of small holes opened on its bottom wall, and transferred to the surface of the pipeline. When the detector body 1 is pushed to slide on the pipeline, the scraper 13 set in contact with the pipeline can collect the used lubricating oil under the action of its inclined surface, and then transfer it to the inner wall of the storage box 14 for collection by gravity, and repeat this step. This step is coordinated with the scraper 13 set in deep contact with the pipeline, and the used lubricating oil can be transferred to the inner wall of the storage box 14 again, reducing the problem of lubricating oil material being directly smeared on the pipeline surface, which makes the subsequent cleaning troublesome, and at the same time reduces the waste of lubricating oil material. Under the action of the two sets of pump bodies 15, the problem of lubricating oil smearing and pushing the instrument separately can be reduced, thereby reducing the labor intensity of the staff.

[0027] like Figure 3 and 5As shown, two groups of vertical plates 2 are fixedly connected to the top of the detector body 1; a rotating shaft 21 is rotatably connected to the middle of the vertical plate 2; a belt 22 is rotatably connected to the middle of the rotating shaft 21, and the other end of the belt 22 is rotatably connected to the output end of the rotating wheel 11; a half-tooth block 23 is fixedly connected to the middle of the rotating shaft 21; two groups of spring rods 24 are installed on the inner wall of the detector body 1, and a slide plate 25 is fixedly connected to the output end of the spring rod 24, and the slide plate 25 and the half-tooth block 23 are meshed with each other; the half-tooth block 23 is slidably arranged in the middle of the detector body 1; a second connecting frame 26 is fixedly connected to the end of the slide plate 25; a bracket 27 is provided at the end of the slide plate 25, and the middle part of the bracket 27 is arranged in an arc shape; when working, a slidable slide plate 25 is provided on the top of the detector body 1, so that when the rotating wheel 11 as a whole rotates, the belt 22 provided in cooperation It can synchronously drive the rotating shaft 21 to rotate as a whole, and the half-tooth block 23 will push the slide plate 25 to approach the center of the detector body 1. After the teeth in the middle of the half-tooth block 23 are disengaged from the slide plate 25, the slide plate 25 can be reset as a whole under the action of the two sets of spring rods 24, so that the bracket 27 can slide back and forth in the middle of the pipeline and wipe the lubricating oil dripping in the middle of the pipeline evenly. This step cooperates with the bracket 27 to improve the uniformity of the distribution of the lubricating oil in the middle of the pipeline, reduce the blind spots of the lubricating oil dripping directly from the middle of the pipe body 16, and make it difficult for the runner 11 to have deep contact with the lubrication when moving on the pipeline, resulting in greater wear. When the slide plate 25 is reset and impacted under the action of the spring rod 24, the lubricating oil accumulated in the middle of the bracket 27 can be vibrated and cleaned.

[0028] like Figure 2 , 3 As shown in Figure 5, the inner wall of the second connecting frame 26 is slidably connected to the limiting member 3; the bottom of the limiting member 3 is fixedly connected to the bracket 27; a connecting block 31 is fixedly connected to the middle of the second connecting frame 26; a screw 32 is threadedly connected to the middle of the connecting block 31; a connecting member 33 is fixedly connected to the side wall of the bracket 27, and the end of the connecting block 31 is rotatably connected to the connecting member 33; during operation, by setting the limiting member 3 in the middle of the second connecting frame 26, when it is necessary to adjust the distance between the bracket 27 and the pipeline, the staff can use a tool to rotate the screw 32. Because the screw 32 and the connecting member 33 are rotatably connected, and the limiting member 3 is slidably arranged, the bracket 27 can move straight as a whole, and at the same time, the middle part of the soft plate 34 can be squeezed to deform during movement. The screw 32 arranged in conjunction with this step can improve the flexibility of the bracket 27 after use, and adjust the contact force between the soft plate 34 and the pipeline, thereby adjusting the thickness of the applied lubricating oil.

[0029] like Figure 4As shown, two groups of connecting rods 4 are fixedly connected to the outer wall of the scraper 13; the connecting rod 4 is fixedly connected to the end of the connecting rod 4, and the middle part of the frame plate 41 is inclined; the inner wall of the frame plate 41 is fixedly connected to the filter screen 42; during operation, by arranging an inclined filter screen 42 on the inner wall of the storage box 14, the lubricating oil on the pipeline will first be assisted by the inclined filter screen 42 when it falls and transfers, and the lubricating oil will be transferred to the inner wall of the storage box 14 through the filter screen 42 for collection, and the impurities contained in the lubricating oil will be blocked by the edge of the raised frame plate 41. This step cooperates with the set filter screen 42 to improve the cleanliness of the lubricating oil transferred to the inner wall of the storage box 14, reduce the transfer of more impurities to the inside of the storage box 14, so that the subsequent pump body 15 will not be blocked in the middle when it is working for a long time, and reduce the need for staff to frequently maintain or clean the pump body 15.

[0030] like Figure 5 As shown, two groups of reinforcing rods 5 are fixedly connected to the top of the vertical plate 2; a top plate 51 is fixedly connected to the top of the reinforcing rods 5; when working, by arranging two groups of reinforcing rods 5 on the top of the vertical plate 2, the reinforcing rods 5 can support the top plate 51, and the top plate 51 can block the impurities floating from the outside of the detector body 1. In this step, under the action of the top plate 51, the adhesion of more impurities to the surface of the half-tooth block 23 is reduced, and the problem of jamming or large wear during the subsequent meshing between the half-tooth block 23 and the slide plate 25 is reduced.

[0031] like Figure 2 As shown, a rubber pad 6 is provided on the inner wall of the scraper 13; during operation, by providing the rubber pad 6 on the inner wall of the scraper 13, when the staff pulls the scraper 13 to move as a whole, the rubber pad 6 will deeply contact with the surface of the pipeline. In this step, under the action of the soft material rubber pad 6, the sealing performance of the scraper 13 for collecting lubricating oil materials can be improved, the problem of lubricating oil leakage when the detector body 1 slides can be reduced, and the accuracy of cleaning the pipeline surface can be improved.

[0032] like Figure 3 As shown, the end of the tube body 16 is fixedly connected with a connecting rope 7, and the other end of the connecting rope 7 is fixedly connected to the end of the adjacent tube body 16; when working, by arranging a rubber pad 6 at the end of the tube body 16, the rubber pad 6 can reinforce the ends of the two groups of tube bodies 16. This step cooperates with the rubber pad 6 to reduce the problem of frequent shaking and deformation in the middle of the detector body 1 due to the uneven amount of lubricating oil accumulated inside when the detector body 1 is in motion.

[0033] Working principle: by connecting the detector body 1 and the display device together, and then placing the detector body 1 on the pipeline, the rotating wheel 11 is in direct contact with the pipeline, and by setting a scraper 13 in the middle of the detector body 1, the staff can first add a proper amount of lubricating oil to the inner walls of the two sets of storage boxes 14 when pushing the detector body 1, and then start the two sets of pump body 15 switches, and cooperate with the pipe body 16 and the multiple sets of small holes opened on its bottom wall to spray the lubricating oil evenly and transfer it to the surface of the pipeline. When the detector body 1 is pushed to slide on the pipeline, the scraper 13 set in contact with the pipeline on its inclined surface Under the action, the used lubricating oil can be collected together, and then transferred to the inner wall of the storage box 14 by gravity for collection, and this process is repeated. By providing a slidable slide plate 25 on the top of the detector body 1, when the rotating wheel 11 rotates as a whole, the belt 22 provided in conjunction can synchronously drive the rotating shaft 21 to rotate as a whole, and the half-tooth block 23 will push the slide plate 25 to approach the center of the detector body 1. After the teeth in the middle of the half-tooth block 23 are disengaged from the slide plate 25, the slide plate 25 can be reset as a whole under the action of the two sets of spring rods 24, so that the bracket 27 can be in the pipeline. The support 27 is reciprocated and the lubricating oil dripping on the middle of the pipeline is wiped evenly. By setting a limiting member 3 in the middle of the second connecting frame 26, when the distance between the bracket 27 and the pipeline needs to be adjusted, the staff can use a tool to rotate the screw 32. Since the screw 32 and the connecting member 33 are rotatably connected and cooperate with the limiting member 3 set for sliding, the bracket 27 can move straight as a whole, and the middle part of the soft plate 34 can be squeezed and deformed during the movement. By setting an inclined filter screen 42 on the inner wall of the storage box 14, the lubricating oil on the pipeline will first interact with the inclined filter screen 42 when it falls and is transferred. The lubricating oil will be transferred to the inner wall of the storage box 14 through the filter screen 42 for collection, and the impurities contained in the lubricating oil will be blocked by the edge of the raised frame plate 41. By arranging two groups of reinforcing rods 5 on the top of the vertical plate 2, the reinforcing rods 5 can support the top plate 51, and the top plate 51 can block the impurities floating from the outside of the detector body 1. By arranging rubber pads 6 on the inner wall of the scraper 13, when the staff pulls the scraper 13 as a whole to move, the rubber pads 6 will deeply contact the surface of the pipeline. By arranging rubber pads 6 at the ends of the tube bodies 16, the rubber pads 6 can reinforce the ends of the two groups of tube bodies 16.
