DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Example 1:

[0033] This embodiment provides a drainage hole opening device for waterproofing renovation of a house, specifically as follows: Figures 1-3 As shown, the device includes a mounting frame 1, on which an adjusting frame 3 is mounted. The adjusting frame 3 includes a fixed part and a movable part. The movable part is provided with an opening area, a refining area, and a coarsening area. The opening area is provided with an opening component 4, the refining area is provided with a refining component 5, and the coarsening area is provided with a coarsening component 6. The movable part includes a movable frame, on which a driving unit is provided. The driving unit is used to drive the opening component 4, the refining component 5, and the coarsening component 6 to operate. Each functional area on the movable frame is equipped with a cylinder 301. The opening component 4, the refining component 5, and the coarsening component 6 are respectively connected to the corresponding cylinder 301 for transmission. The cylinder 301 is used to control the transmission relationship between the driving unit and the opening component 4, the refining component 5, and the coarsening component 6.

[0034] When drilling is required, the drilling component 4 is first placed close to the building body 2. The cylinder 301 in the drilling area extends, connecting the drive unit with the drilling component 4. The drive unit then starts, driving the drilling component 4 to perform the drilling operation. The cylinder 301 continues to extend, causing the drilling component 4 to continuously advance. After drilling is completed, the drilling component 4 is retracted, and the refining component 5 or the coarsening component 6 is switched as needed to further process the hole drilled by the drilling component 4. When a drainage pipe needs to be directly inserted into the drainage hole, the refining component 5 can be used to grind the inner wall of the drainage hole to prevent damage to the pipe caused by the rough inner wall of the drainage hole, thus protecting the drainage pipe that will be inserted later. When the drainage pipe needs to be sealed with expanding foam or polyurethane foam after being inserted into the drainage hole, the coarsening component 6 can be used to further coarse the inner wall of the drainage hole to prevent the expanding foam or other materials from detaching from the drainage hole when the drainage pipe moves, and to increase the adhesion of the expanding foam.

[0035] Example 2:

[0036] This embodiment further expands upon the above embodiment by modifying the adjustment frame 3, the opening assembly 4, the refining assembly 5, and the coarsening assembly 6, specifically as follows: Figures 5-6As shown, the drive unit includes a main motor 307 mounted on a movable frame, and a drive gear shaft 310 is mounted on the output end of the main motor 307. The multiple functional areas are arranged in a circular array with the main motor 307 as the center.

[0037] like Figure 8 As shown, the opening assembly 4 includes an opening shaft 405, on which a first gear 401 and a protective cover 402 are mounted. The first gear 401 meshes with the drive gear shaft 310 to transmit power. A second spring 406 is provided between the protective cover 402 and the first gear 401. Multiple guide plates 407 are mounted at the end of the opening shaft 405, and opening teeth 408 are mounted on the guide plates 407. The opening shaft 405 is connected to the cylinder 301 in the opening area.

[0038] When the hole-opening assembly 4 needs to open a hole, the cylinder 301 extends. At this time, the first gear 401 begins to mesh with the drive gear shaft 310. After the main motor 307 is started, the drive gear shaft 310 drives the first gear 401 to rotate. The first gear 401 drives the hole-opening shaft 405 to rotate. At this time, the protective cover 402 presses against the building body 2 under the action of the second spring 406. Since the protective cover 402 is only sleeved on the hole-opening shaft 405, the protective cover 402 will not rotate, while the guide plate 407 is opened. The shaft 405 rotates, and the drilling tooth 408 begins to drill through the wall. The dust generated is blocked by the protective cover 402. As the cylinder 301 continues to extend, the drilling depth of the drilling tooth 408 becomes deeper and deeper. At this time, the compression of the second spring 406 increases. When the drilling is completed, the cylinder 301 retracts, and the drilling shaft 405 retracts synchronously. The first gear 401 disengages from the drive gear shaft 310, and the protective cover 402 detaches from the building body 2. At this time, the dust falls and can be collected by personnel.

[0039] like Figure 7 As shown, the refining component 5 includes a grinding shaft 505, on which a second gear 501 and a rocker arm 507 are mounted. The rocker arm 507 is connected to the grinding shaft 505 via a ball joint. The second gear 501 meshes with the drive gear shaft 310 to transmit power. A bracket 506 is rotatably connected to the grinding shaft 505. The bracket 506 is slidably connected to the movable frame. A cross shaft 508 is rotatably connected to the bracket 506. The cross shaft 508 is rotatably connected to the rocker arm 507. A grinding ring 502 is fixedly connected to the rocker arm 507. The grinding shaft 505 is connected to the cylinder 301 of the refining zone via a transmission connection.

[0040] When the hole wall needs to be refined and polished, the cylinder 301 is extended, at this time the second gear 501 starts to engage with the driving gear shaft 310, after starting the main motor 307, the driving gear shaft 310 drives the second gear 501, the second gear 501 drives the polishing shaft 505 to rotate, because the support 506 slides on the movable frame, the support 506 will not rotate, at this time the polishing shaft 505 drives the swing arm 507 to swing, so as to realize the continuous swing of the polishing ring 502, when the polishing ring 502 swings, because the outer wall surface of the polishing ring 502 is spherical, after the polishing ring 502 wall surface is attached to the hole wall, the hole wall will be continuously polished to prevent the subsequent inserted drain pipe from being damaged due to the roughness of the hole wall being too large; after polishing, the cylinder 301 is retracted, at this time the second gear 501 is disengaged from the driving gear shaft 310.

[0041] As shown in Figures 9-10 The roughening assembly 6 includes a roughening box 602, a third gear 601 is installed on the roughening box 602, the third gear 601 is engaged with the driving gear shaft 310 to realize power transmission; a telescopic rod frame 610 is rotatably connected on the roughening box 602, a plurality of telescopic rods 603 are installed on the telescopic rod frame 610, the telescopic rods 603 are slidingly connected on the movable frame, a fifth gear 609 is fixedly connected on the telescopic rod frame 610, a lead screw 604 is rotatably connected on the roughening box 602, a fourth gear 608 is installed on the lead screw 604, the fourth gear 608 is engaged with the fifth gear 609, a moving seat 607 is slidingly connected on the roughening box 602, the moving seat 607 is threadedly connected with the lead screw 604, a carving tooth 606 is slidingly connected on the moving seat 607, an extrusion spring 605 is arranged between the carving tooth 606 and the moving seat 607; the roughening box 602 is drivingly connected with the cylinder 301 of the roughening area.

[0042] When the hole wall needs to be roughened, the cylinder 301 extends, at which time the third gear 601 begins to mesh with the driving gear shaft 310. After the main motor 307 is started, the driving gear shaft 310 drives the third gear 601 to rotate, the third gear 601 drives the roughening box 602 to rotate, the roughening box 602 drives the fourth gear 608 to revolve, since the telescopic rod 603 is slidingly connected to the movable frame, the telescopic rod holder 610 will not rotate, thus the fourth gear 608 will begin to rotate due to the meshing with the fifth gear 609, the revolution of the fourth gear 608 and the elastic force of the compression spring 605 cause the carving tooth 606 to press on the hole wall to perform carving, the telescopic rod 603 is pressed on the building body 2, and the rotation of the fourth gear 608 drives the lead screw 604 to rotate, so that the moving seat 607 moves laterally on the roughening box 602, so that the movement track of the carving tooth 606 is a spiral line, that is, the carving tooth 606 carves a spiral groove in the hole wall, and the telescopic rod 603 continuously contracts. After the carving is completed, the main motor 307 reverses rotation, so that the moving seat 607 returns to the original position, and the cylinder 301 retracts until the third gear 601 is disengaged from the driving gear shaft 310. Through the roughening operation, after the drainage pipe is arranged later, the spiral groove carved by the carving tooth 606 can be used when the foaming glue is filled, so as to enhance the adhesion of the foaming glue and the building body 2, and prevent loosening at the sealing position.

[0043] In another specific embodiment, as shown in Figures 7-8 The first connecting sleeve 403 is rotatably connected to the hole opening shaft 405, and the first spring 404 is arranged between the hole opening shaft 405 and the first connecting sleeve 403. The second connecting sleeve 503 is rotatably connected to the polishing shaft 505, and the third spring 504 is arranged between the polishing shaft 505 and the second connecting sleeve 503. The first spring 404 and the third spring 504 have the same effect, that is, when the hole opening assembly 4 or the refining assembly 5 is working, the cylinder 301 extends at a constant speed, but the excavation speed of the hole opening tooth 408 or the polishing speed of the polishing ring 502 is determined according to the material of the building body 2. If there is a hard material such as a stone in the building body 2, the working speed will be reduced. In order to prevent the hole opening tooth 408 or the polishing ring 502 from being damaged, the first spring 404 or the third spring 504 is arranged to provide buffering.

[0044] The other parts of the embodiment are the same as those of the above-described embodiment, and will not be described again.
