Description

Technical Field

[0001] This application relates to the field of waterproof coatings for walls, and in particular to waterproof walls for prefabricated residential buildings. Background Technology

[0002] Currently, prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories, where building components and accessories are prefabricated, transported to the construction site, and assembled on-site.

[0003] Relevant technology can be found in Chinese Utility Model Patent No. CN210947197U, which discloses a waterproof coating structure, including an inner layer structure covering the surface of an exterior wall and a surface layer structure. A channel steel is fixed to the surface of the exterior wall, and the channel steel is embedded in the inner layer structure. The cross-section of the channel steel is trapezoidal, and the channel opening is the top surface of the trapezoid with a smaller area, and the channel opening is connected to the surface of the inner layer structure. The surface of the inner layer structure is covered with a waterproof layer. A retaining strip is provided on the side of the waterproof layer away from the inner layer structure, and the retaining strip, together with part of the waterproof layer, is secured to the channel steel. The inner layer structure covers the waterproof layer.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the waterproof coating applied to the waterproof wall will peel off during long-term use, requiring manual recoating based on the specific peeling location. Although a machine can also be used to apply the coating to the brushed area, there is a problem that the machine cannot automatically identify the peeling location, ultimately requiring manual positioning of the machine's coating location. Summary of the Invention

[0005] To address the issue of the inability to automatically identify the location of coating peeling, this application provides a prefabricated residential waterproof wall.

[0006] The prefabricated residential waterproof wall provided in this application adopts the following technical solution:

[0007] A prefabricated residential waterproof wall includes a wall body and a coating applied to the surface of the wall body. A sealed box for storing the coating and a coating tank embedded within the wall body are fixed inside the wall body. A pump body is installed between the coating tank and the sealed box. Several coating assembly units are installed inside the wall body. Several feed pipes are connected to the bottom of the coating tank and are connected to the coating assembly units. The coating assembly includes a ladder plate rotatably mounted inside the wall body. A discharge hole is opened on the inclined ladder surface of the ladder plate. A rotating groove is opened on the surface of the wall body, and both sides of the ladder plate are rotatably connected to the inner wall of the rotating groove. An electromagnet is fixed to one side of the rotating groove, and a rotating shaft is slidably connected to the other side along the length of the ladder plate. A rotating groove that can engage with the rotating shaft is opened on the side wall of the ladder plate. A magnetic suction piece that can attract the electromagnet is fixed to the end of the rotating shaft. A rotating assembly for driving the ladder plate to rotate is installed between the rotating shaft and the rotating groove. A photoresistor is fixed on the ladder plate, and the photoresistor, the electromagnet, and the power supply form a series circuit.

[0008] By employing the above technical solution, after the coating peels off, the photoresistor, no longer obstructed by the coating, is exposed to light, thus reducing its resistance. This increases the current in the circuit where the photoresistor and electromagnet are connected in series, strengthening the magnetism of electromagnet. Electromagnet then attracts the magnetic plate, causing the rotating axis to move closer to electromagnet. During this movement, the rotating axis engages with the ladder plate, causing it to rotate. As the ladder plate rotates, the discharge hole on it faces towards the coating side, facilitating the discharge of paint flowing into the ladder plate and repairing the peeled coating.

[0009] Optionally, the rotating assembly includes a plurality of spiral protrusions evenly distributed around the circumference of the rotating shaft and a plurality of spiral grooves evenly distributed around the inner wall of the rotating groove.

[0010] By adopting the above technical solution, as the spiral protrusion moves axially along the rotation axis, it applies a rotational torque to the ladder plate by pressing against the spiral groove, thereby driving the ladder plate to rotate.

[0011] Optionally, a second connecting groove is provided on the side wall of the rotating groove, and a second spring is fixed on the side wall of the second connecting groove away from the first connecting groove. The end of the second spring near the first connecting groove is fixedly connected to the rotating shaft.

[0012] By adopting the above technical solution, the rotating shaft of the spring provides a spring force to return to the side away from the electromagnet.

[0013] Optionally, a solenoid valve is provided on the feed pipe; the solenoid valve includes a valve body fixed to the feed pipe, a valve tube fixed around the valve body, and a valve shaft slidably connected to the valve tube along its own axial direction; a valve plate is fixed to the end of the valve shaft away from the feed pipe; an installation groove is provided in the wall that can be slidably connected to the valve plate along the feed pipe radially; an electromagnet is fixed to the inner wall of the installation groove away from the feed pipe, and a magnetic suction piece is fixed to the side of the valve plate away from the feed pipe that can be attracted to the electromagnet; the photoresistor is connected in series with the electromagnet and the power supply.

[0014] By adopting the above technical solution, after the resistance of the photoresistor decreases, the current through the first electromagnet increases, thereby enhancing the magnetism of the first electromagnet. The first electromagnet drives the valve plate to move by adsorbing the first magnetic accumulator. The valve plate is used to block the flow of fluid. When the valve plate moves, the solenoid valve opens.

[0015] Optionally, a spring is fixed to the side of the valve plate away from the feed pipe, and the end of the spring away from the valve plate is fixedly connected to the side of the mounting groove away from the feed pipe.

[0016] By adopting the above technical solution, spring 1 is used to provide elastic force for the valve plate to reset to the side away from electromagnet 1.

[0017] Optionally, the top, side and bottom surfaces of the rotating groove are respectively provided with receiving grooves; a pressure plate is slidably installed on the wall through the receiving groove, and a return spring is fixed on the side of the pressure plate away from the ladder plate, and the end of the return spring away from the ladder plate is fixedly connected to the inner wall of the receiving groove.

[0018] By adopting the above technical solution and setting a sliding pressure plate, the volume of the receiving groove can be increased, making it easier for the ladder plate to rotate.

[0019] Optionally, the ladder plate has a groove on the side near the coating; the ladder plate is vertically slidably connected to an anti-collision plate through the groove; a spring is fixed to the bottom of the anti-collision plate, and the bottom end of the spring is fixedly connected to the bottom wall of the groove; a dovetail block is fixed to the side of the anti-collision plate away from the coating, and a dovetail groove is formed on the side of the groove away from the coating, and the dovetail block is vertically slidably connected to the ladder plate through the dovetail groove.

[0020] By adopting the above technical solution, the dovetail groove one provides guidance for the dovetail block one, reducing the possibility of the anti-collision plate deviating from the track during vertical movement. Spring three provides the anti-collision plate with an upward restoring force.

[0021] Optionally, the bottom surface of the ladder plate is provided with a sliding groove, and the ladder plate is connected to a sliding piece 1 by sliding vertically through the sliding groove; the side wall of the retention groove away from the coating is provided with a sliding groove 2, and the ladder plate is connected to a sliding piece 2 by sliding along its own width direction through the sliding groove 2; the inner sides of the sliding piece 1 and the sliding piece 2 are respectively provided with inclined surfaces 1; the side of the anti-collision plate away from the coating is provided with a slot that can be inserted into the sliding piece 2, and the top of the sliding piece 2 near the coating and the top wall of the slot are respectively provided with inclined surfaces 2 that can abut against each other.

[0022] By adopting the above technical solution, when the ladder plate abuts against the wall of the mounting groove, sliding plate one presses against sliding plate two, and keeps the sliding plates in an inserted state with the slot of the anti-collision plate, thereby keeping the anti-collision plate in an upward moving state. This reduces the possibility of paint flowing into the mounting groove when the paint flows downward over the anti-collision plate.

[0023] Optionally, a guide plate is fixed on the top surface of the second sliding plate, and a guide groove is provided on the top surface of the second sliding groove. The guide plate is slidably connected to the ladder plate through the guide groove. A spring four is fixed on the side of the guide plate away from the anti-collision plate, and the end of the spring four away from the anti-collision plate is fixedly connected to the side wall of the second sliding groove away from the anti-collision plate.

[0024] By adopting the above technical solution, spring four provides elastic force for slide two to move closer to slide one, so that after slide one separates from the wall of the mounting groove, slide two can separate from the slot.

[0025] Optionally, the ladder plate is slidably connected to an abutment piece along its length via the retention groove; the top of the abutment piece has a chamfer on the side away from the coating that can abut against the bottom of the anti-collision plate; a dovetail block two is fixed to the bottom of the abutment piece, and a dovetail groove two is formed on the top surface of the retention groove that can be slidably connected to the dovetail block two; a spring five is fixed to the side of the dovetail block two away from the coating, and the end of the spring five away from the coating is fixedly connected to the side of the dovetail groove two away from the coating.

[0026] By adopting the above technical solution, when the anti-collision plate moves upward, the side of the abutment piece away from the ladder plate is coplanar with the side of the anti-collision plate away from the ladder plate, reducing the possibility of paint flowing into the gap between the anti-collision plate and the ladder plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. After the coating peels off, the photoresistor is exposed to light without the coating blocking it, causing its resistance to decrease. This increases the current in the circuit where the photoresistor and electromagnet are connected in series, strengthening the magnetism of electromagnet. Electromagnet attracts the magnetic plate, causing the rotating axis to move closer to the electromagnet. During this movement, the rotating axis engages with the ladder plate, causing it to rotate. As the ladder plate rotates, the discharge hole on it faces towards the side closer to the coating, allowing the paint flowing into the ladder plate to exit through the discharge hole, thus repairing the peeled coating.

[0029] 2. When the ladder plate abuts against the wall of the mounting groove, slider one presses against slider two, keeping the sliders in an inserted state with the slot of the anti-collision plate, thereby keeping the anti-collision plate in an upward moving state. This reduces the possibility of paint flowing into the mounting groove when the paint flows downward over the anti-collision plate;

[0030] 3. When the crash barrier moves upward, the side of the abutment piece away from the ladder plate is coplanar with the side of the crash barrier away from the ladder plate, reducing the possibility of paint flowing into the gap between the crash barrier and the ladder plate.

[0037] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0038] This application discloses an embodiment of a prefabricated residential waterproof wall. (Refer to...) Figure 1 and Figure 2 The prefabricated residential waterproof wall includes a wall body 1 and a coating applied to the surface of the wall body 1. A touch-up paint system 2 is installed within the wall body 1 for repairing the coating on the wall body 1.

[0039] Reference Figure 1 and Figure 2 The touch-up paint system 2 includes a sealed box 11 embedded in the wall 1 for storing paint and a paint tank 12 embedded in the wall 1. The sealed box 11 is located at the bottom of the wall 1, and the paint tank 12 is located at the top of the wall 1. The sealed box 11 is used to seal the paint, and a pump body 13 is provided between the paint tank 12 and the sealed box 11 for sucking the paint in the sealed box 11 into the paint tank 12.

[0040] Reference Figure 2 The bottom of the paint tank 12 is connected to several feed pipes 61, and a solenoid valve 3 is installed on each feed pipe 61. Several sets of coating components 4 are installed inside the wall 1 for applying a coating to the wall 1 after the original coating has peeled off. The outlet end of the feed pipes 61 is connected to the coating components 4.

[0041] Reference Figure 1 , Figure 2 and Figure 3The solenoid valve 3 includes a valve body 31 fixed to the feed pipe 61, a valve pipe 32 fixed around the valve body 31, and a valve shaft 33 slidably connected within the valve pipe 32 along its own axial direction. A valve plate 34 is fixed to the end of the valve shaft 33 away from the feed pipe 61. An installation groove 14 is provided in the wall 1, which can be slidably connected to the valve plate 34 along the feed pipe 61. A spring 15 is fixed to the side of the valve plate 34 away from the feed pipe 61, and the end of the spring 15 away from the valve plate 34 is fixedly connected to the side of the installation groove 14 away from the feed pipe 61. An electromagnet 21 is fixed to the inner wall of the installation groove 14 away from the feed pipe 61, and a magnetic suction piece 22 that can be attracted to the electromagnet 21 is fixed to the side of the valve plate 34 away from the feed pipe 61.

[0042] The valve shaft 33 is used to extend into the valve tube 32 to isolate the coating inside the valve body 31. The spring 15 provides power for the movement of the valve shaft 33 towards the side closer to the feed tube 61; the electromagnet 21 can move the valve shaft 33 away from the feed tube 61 by attracting the magnetic plate 22.

[0043] Reference Figure 2 and Figure 4 The coating assembly 4 includes a ladder plate 6 rotatably mounted within the wall 1. The ladder plate 6 is hollow, and a discharge hole 42 is provided on its inclined ladder surface. The discharge end of the feed pipe 61 is connected to the ladder plate 6 to transport the coating into the ladder plate 6, which then flows out through the discharge hole 42. A rotating groove 43 for mounting the ladder plate 6 is provided on the surface of the wall 1. The rotating groove 43 is a square groove, and receiving grooves 44 are provided on its top, side, and bottom surfaces. Pressure plates 45 are slidably mounted on the wall 1 through the receiving grooves 44. The three pressure plates 45 abut against the short bottom surface, long bottom surface, and side surface of the ladder plate 6, respectively. A return spring 41 is fixed to the side of the pressure plate 45 away from the ladder plate 6, and the end of the return spring 41 away from the ladder plate 6 is fixedly connected to the inner wall of the receiving groove 44.

[0044] Because the distance between the top corner of the ladder plate 6 and the center of the rotation shaft 5 is relatively large when the ladder plate 6 is flipped, the side length of the mounting groove 14 needs to be increased. By setting a pressure plate 45, the internal volume of the mounting groove 14 can be increased by pressing against the pressure plate 45 when the ladder plate 6 is flipped.

[0045] Reference Figure 2 and Figure 4The two sides of the ladder plate 6 are rotatably connected to the inner walls of the rotating groove 43. A first connecting groove is formed on one side of the rotating groove 43, and an electromagnet 24 is fixed to the inner wall of the first connecting groove away from the rotating groove 43. A second connecting groove is formed on the side wall of the rotating groove 43 away from the first connecting groove, and a spring 26 is fixed to the side wall of the second connecting groove away from the first connecting groove. A rotating shaft 5 is fixed to the end of the spring 26 near the first connecting groove. A rotating groove 51 is formed on the side wall of the ladder plate 6, which can engage with the rotating shaft 5. A magnetic suction piece 52, which can be attracted to the electromagnet 24, is fixed to the end of the rotating shaft 5 away from the spring 26. The rotating shaft 5 has several spiral protrusions 53 evenly distributed along its circumference, and the inner wall of the rotating groove 51 has several spiral grooves 54 evenly distributed along its circumference.

[0046] When electromagnet 24 is energized, it drives rotating shaft 5 to move closer to electromagnet 24 by attracting magnetic plate 52. During the movement, rotating shaft 5 engages with rotating groove 51, thereby causing ladder plate 6 to flip. Ladder plate 6 flips from right-angle surface facing coating to ladder surface facing coating.

[0047] Reference Figure 4 and Figure 5 A groove 23 is provided on the side of the ladder slab 6 closest to the coating. A crash barrier 62 is vertically connected to the ladder slab 6 via the groove 23. A spring 63 is fixed to the bottom of the crash barrier 62, and the bottom end of the spring 63 is fixedly connected to the bottom wall of the groove 23. A dovetail block is fixed to the side of the crash barrier 62 furthest from the coating, and a dovetail groove is provided on the side of the groove 23 furthest from the coating. The dovetail block is vertically connected to the ladder slab 6 via the dovetail groove.

[0048] When the ladder plate 6 is flipped towards the side closer to the coating, because the distance between the top corner of the ladder plate 6 and the center of the rotation axis 5 of the ladder plate 6 is relatively large, the top corner of the ladder plate 6 will come into contact with the coating and cause more coating to peel off. When the ladder plate 6 is flipped, the distance between the top corner of the ladder plate 6 and the center of the rotation axis 5 of the ladder plate 6 can be shortened by moving the anti-collision plate 62 downward.

[0049] Reference Figure 5The bottom surface of the ladder plate 6 has a sliding groove 71, through which the ladder plate 6 slides vertically and is connected to a sliding piece 72. The side wall of the retaining groove 23 away from the coating has a sliding groove 73, through which the ladder plate 6 slides along its width and is connected to a sliding piece 74. The inner sides of the sliding pieces 72 and 74 each have an inclined surface 75. The side of the anti-collision plate 62 away from the coating has a slot for insertion into the sliding piece 74. The top of the sliding piece 74 near the coating and the top wall of the slot each have inclined surfaces 75 that abut against each other. A guide piece 78 is fixed to the top surface of the sliding piece 74. A guide groove 79 is formed on the top surface of the sliding groove 73, through which the guide piece 78 slides and is connected to the ladder plate 6. A spring 7 is fixed to the side of the guide piece 78 away from the anti-collision plate 62, and the end of the spring 78 away from the anti-collision plate 62 is fixedly connected to the side wall of the sliding groove 73 away from the anti-collision plate 62.

[0050] When the ladder plate 6 is stationary, its right-angled surface abuts against the side or bottom wall of the retaining groove 23, and the sliding piece 1 72 retracts into the sliding groove 2 73. At this time, the sliding piece 1 72 and the sliding piece 2 74 are in contact. The sliding piece 2 74, through its insertion into the slot, causes the anti-collision plate 62 to move upward. The anti-collision plate 62 can protect the side of the ladder plate 6 near the coating, reducing the possibility of the coating falling into the retaining groove 23 when sliding downward. When the ladder plate 6 flips, the sliding piece 2 74 moves away from the anti-collision plate 62 under the action of the spring 4 7, thereby separating the sliding piece 2 74 from the anti-collision plate 62. The anti-collision plate 62 returns to its original position under the pulling force of the spring 3 63.

[0051] Reference Figure 5 The ladder plate 6 is slidably connected to an abutment piece 81 along its length via a groove 23. The top of the abutment piece 81, away from the coating, has a chamfer 82 that abuts against the bottom of the anti-collision plate 62. A dovetail block 83 is fixed to the bottom of the abutment piece 81, and a dovetail groove 23 is formed on the top surface of the groove 23 that can slidably connect with the dovetail block 83. A spring 25 is fixed to the side of the dovetail block 83 away from the coating, and the end of the spring 25 away from the coating is fixedly connected to the side of the dovetail groove 2 away from the coating.

[0052] The abutment piece 81 is used to prevent paint from falling into the gap between the bottom of the anti-collision plate 62 and the bottom surface of the retention groove 23. When the abutment piece 81 moves downward, it moves closer to the coating. When the abutment piece 81 returns to its original position, it moves closer to the feed pipe 61, so that the abutment piece 81 and the side away from the discharge pipe are coplanar with the side of the anti-collision plate 62 away from the discharge pipe.

[0053] Reference Figure 1A photoresistor 8 is embedded and fixed at the top corner of the anti-collision plate 62. The photoresistor 8 forms a series circuit with electromagnet 21 and electromagnet 24, respectively. The photoresistor 8 is connected in series with the power supply. The anti-collision plate 62 with the photoresistor 8 corresponds to the solenoid valve 3 with electromagnet 21, so that when the resistance of the photoresistor 8 changes, the magnetic change of electromagnet 21 affects the material entering the feed pipe 61. The anti-collision plate 62 with the photoresistor 8 corresponds to the coating assembly 4 with electromagnet 24, so that when the resistance of the photoresistor 8 changes, the magnetic change of electromagnet 24 affects the rotation of the ladder plate 6.

[0054] After the coating peels off, the resistance of the photoresistor 8 decreases when exposed to light, thereby increasing the current in the series circuit formed by the photoresistor 8 and electromagnet 21, and the photoresistor 8 and electromagnet 24, and enhancing the magnetism of electromagnet 21 and electromagnet 24.

[0055] The implementation principle of the prefabricated residential waterproof wall in this application embodiment is as follows:

[0056] After the coating peels off, the resistance of the photoresistor 8 decreases when exposed to light, thereby increasing the current in the series circuit formed by the photoresistor 8 and electromagnet 21, and the photoresistor 8 and electromagnet 24, and enhancing the magnetism of electromagnet 21 and electromagnet 24.

[0057] When the power supply to the pump body 13 is turned on, the paint in the sealed box 11 is drawn into the paint box 12. At this time, the electromagnet 21 connected in series with the photoresistor 8 is in the open state. The electromagnet 21 attracts the magnetic plate 22, which can make the valve shaft 33 move away from the feed pipe 61. The solenoid valve 3 opens, and the paint enters the feed pipe 61 and flows into the ladder plate 6 corresponding to the photoresistor 8.

[0058] When the resistance of photoresistor 8 changes, the corresponding electromagnet 24 is activated. Electromagnet 24, through the attraction of magnetic plate 52, drives the rotating shaft 5 to move closer to electromagnet 24. During the movement, the rotating shaft 5 engages with the rotating groove 51, thereby causing the ladder plate 6 to flip. The ladder plate 6 flips from the right-angle surface facing the coating to the ladder surface facing the coating. At the same time, the paint flowing into the ladder plate 6 flows out downward through the discharge hole 42 on the inclined ladder surface. During the paint outflow process, the peeling parts of the paint on the wall 1 are repaired.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
