DETAILED DESCRIPTION

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0041] <Example 1>

[0042] like Figures 1 to 8 As shown in the figure, this embodiment provides an end sealing device 10 for prefabricated components, used for sealing the ends of prefabricated components 20. The end sealing device 10 includes a sealing plate 1 and a sealing part 2 protruding from the sealing plate 1. A plurality of sealing parts 2 are spaced apart and correspond one-to-one with the holes 201 at the ends of the prefabricated components 20. The sealing parts 2 are used to seal the holes 201 to prevent water from entering the holes 201. The sealing part 2 includes a magnetic element 21. After the sealing plate 1 is installed on the prefabricated component 20, the magnetic element 21 is inserted into the end holes 201 of the prefabricated component for positioning. In the above technical solution, the sealing plate 1 covers the end of the prefabricated component 20, and the magnetic element 21 is inserted into the hole 201 and magnetically connected to the pre-embedded sleeve 202 inside the prefabricated component 20. Through the above technical solution, multiple holes can be sealed simultaneously by the sealing plate, eliminating the need to seal them one by one, thus improving efficiency; in addition, the magnetic positioning of the magnetic element and the pre-embedded sleeve prevents the sealing device from falling off.

[0043] Furthermore, the magnetic component 21 has a guide end 211, the diameter of which is smaller than the diameter of the end hole 201. In this embodiment, the hole 201 is a circular hole. When the magnetic component 21 is inserted into the hole 201, the smaller diameter of the guide end 211 facilitates insertion. Specifically, the magnetic component 21 is tapered, meaning its diameter gradually increases from the guide end 211 towards the sealing plate, forming a frustum shape, thus allowing the magnetic component 21 to fit more closely to the hole. Figure 6 As shown, as an improvement, the sealing part 2 includes an annular part 22 connected to the sealing plate 1. One end of the magnetic element 21 is connected to the annular part 22. The annular part 22 seals the opening of the hole, thereby further enhancing the sealing performance. The annular part 22 is made of an elastic material, such as rubber.

[0044] Furthermore, the magnetic component 21 includes a plurality of spaced-apart magnets 212, each magnet 212 being arc-shaped and vertically arranged. In this embodiment, three arc-shaped magnets are provided, arranged in a ring, and the guide end 211 is formed by the three magnets 212. Through the spaced-apart arc-shaped magnets, when the magnetic component 21 is inserted into the hole, the magnets can retract inwards, allowing insertion even when there is a slight deviation between the hole and the magnetic component 21.

[0045] Further, the sealing plate 1 is provided with a hollow part 11, which saves material and reduces weight under the condition of ensuring structural strength. The sealing part 2 is arranged at the edge of the sealing plate 1, and the sealing part 2 is arranged around the sealing plate 1, so that the sealing plate 1 can be more stable when connected with the end of the prefabricated component 20. Specifically, the shape of the sealing plate 1 is the same as the cross section of the end of the prefabricated component 20, and the sealing plate 1 of the embodiment is rectangular, and the sealing part 2 is arranged along the edge length of the sealing plate 1. The sealing plate 1 is made of transparent material, which is convenient for observing the position of the sealing part 2 during installation, aligning the hole, and the sealing plate 1 can use existing transparent lightweight materials such as ABS plastic.

[0046] Further, the sealing plate 1 is provided with a positioning part 12, which is arranged corresponding to the preset hole 203 of the end of the prefabricated component 20. After the positioning part 12 corresponds to the preset hole 203, each sealing part 2 is aligned with the hole 201, which facilitates the alignment of the sealing plate 1 and the prefabricated component 20. Specifically, the positioning part 12 is protruded from the sealing plate 1, and when the sealing plate 1 is installed, the positioning part 12 is inserted into the preset hole 203. During installation, the positioning part 12 is positioned by being connected with the preset hole 203. The positioning part 12 of the embodiment is arranged at the middle part of the sealing plate 1, so that the sealing plate 1 is more stable.

[0047] [Embodiment Two]

[0048] In this embodiment, the same parts as in Embodiment One are given the same reference numerals, and the same textual description is omitted.

[0049] As shown in Figures 8 to 12 , compared with Embodiment One, the end sealing device of the prefabricated component provided by this embodiment also has such a difference in structure design: the sealing plate 1 is provided with a mounting hole 13, which is arranged corresponding to the preset hole 203 of the end of the prefabricated component 20. The sealing plate 1 is connected with the mounting device 30 through the mounting hole 13. After the sealing plate 1 is connected with the mounting device 30, the sealing plate 1 is pressed on the prefabricated component 20 by the mounting device 30, thereby improving the installation efficiency. The mounting device can use existing hand tools or mechanical hands and other automatic equipment.

[0050] Further, the installation device 30 comprises a main body 301, and a telescopic part 302 telescopically connected with the main body 301, and the telescopic part 302 is movable relative to the main body 301. The sealing plate 1 is detachably connected with the telescopic part 302 through the installation hole 13, the sealing plate 1 is assembled with the telescopic part 302, and then is installed on the prefabricated component, and then is separated from the sealing plate 1 through the telescopic part 302. The telescopic part 302 is provided with a sensing block 303, the sensing block 303 is correspondingly arranged with the preset hole 203, and the sensing block 303 is used for sensing the position of the preset hole 203, so that the installation device 30 can be aligned with the prefabricated component. Specifically, the sensing block 303 is provided with a plurality of pressure sensors 304, and the pressure sensors 304 are distributed at the edge position of the sensing block 303. When the sensing block 303 is just inserted into and abuts against the inner wall of the preset hole 203 of the prefabricated component, the plurality of pressure sensors transmit the collected pressure data to the controller, and whether the data value difference between the pressure sensors 304 is within the preset value range is judged through the controller. If it is within the range, it is judged that it has been aligned, if it is not within the range, it is not aligned, and the position needs to be adjusted and then the sensing block 303 is inserted into the preset hole 203 again. For example, the difference between the maximum value and the minimum value of the pressure sensor can be set as the preset value, and the data obtained by the plurality of pressure sensors is compared with the preset value. The sensing block 303 of the embodiment is provided with four sensing blocks, and the four sensing blocks are arranged at four corners.

[0051] Further, the telescopic part 302 is provided with a limiting table 305, the limiting table 305 corresponds to the section part 131 of the installation hole 13, and is clamped on the limiting table 305 through the installation hole 13, so as to facilitate the assembly and separation of the installation hole 13 and the telescopic part 302. The cross sections of the sensing block 303 and the preset hole 203 are both rectangular, avoiding rotation and facilitating limiting. The main body 301 is provided with a handle 306, the handle 306 is provided with a control button 307, the telescopic part 302 can be started by pressing the control button 307, and the telescopic part 302 drives the sensing block 303 to telescope. Specifically, when the sensing block 303 is just inserted into and abuts against the inner wall of the preset hole 203 of the prefabricated component, the four pressure sensors transmit the collected pressure data to the controller, and the control button 307 is unlocked through the controller. If the sensing block 303 is not positioned with the preset hole 203 of the prefabricated component, the pressure difference received by the four pressure sensors exceeds the preset value, and the control button is locked and cannot be pressed, until the position of the sensing block is adjusted. At this time, the control button 307 is pressed, the telescopic part 302 is extended, and the sealing plate is close to the end surface of the prefabricated component, and then the magnetic part is fixedly connected with the embedded sleeve, and then the reset button 308 is pressed, and the telescopic part 302 is retracted. The installation device can adopt an electric push rod, and the telescopic part 302 is the telescopic part of the electric push rod. In the embodiment, the telescopic part 302 and the main body 301 are provided with an elastic element 309, for example, a spring. When the sensing block 303 abuts against the preset hole 203, the telescopic part 302 continues to extend, the elastic element 309 is compressed, so that the sealing plate 1 abuts against the prefabricated component.
