Description

Technical Field

[0001] This utility model relates to the field of chimneys, and in particular to a chimney top displacement detection system. Background Technology

[0002] National standards for chimneys impose limits on the displacement of the chimney top. Current technologies involve installing inclinometers at the top of the chimney or multiple inclinometers on the chimney body to collect data, and then performing complex calculations to obtain the displacement value of the chimney top. This calculation process is generally cumbersome, the system is complex, the information is not intuitive, and regular maintenance is required, resulting in high system costs. Summary of the Invention

[0003] Purpose of the utility model: In order to overcome the shortcomings of the prior art, this utility model discloses a chimney top displacement detection system.

[0004] Technical solution: The chimney top displacement detection system disclosed in this utility model includes:

[0005] A laser information disk is located in the top area of ​​the chimney body;

[0006] A laser source is located outside the chimney body. The emitted laser beam forms a laser point on the laser information disk, converting the chimney's swaying into the displacement of the laser point on the laser information disk.

[0007] A camera assembly is mounted on the chimney body, with its lens facing the surface of the laser information disk.

[0008] Furthermore, the laser information disk is a circular or fan-shaped disk structure, with the initial laser point located at the center of the laser information disk.

[0009] Furthermore, the surface of the laser information disk is provided with scale markings radiating radially from the center.

[0010] Furthermore, the laser information disk is fixed vertically to the outer wall of the chimney body with its disk surface facing downwards, and the laser source is located at the bottom periphery of the chimney body, emitting a laser beam toward the disk surface.

[0011] Furthermore, the laser information disk and the laser source are configured as a one-to-one pair, and there may be one or more pairs.

[0012] Furthermore, the camera assembly is fixed to the outer wall of the chimney body, located below the laser information disk, and corresponds to it one by one.

[0013] Furthermore, the camera component is connected to a data transmission module, which transmits the displacement information of the laser points on the laser information disk to the mobile terminal.

[0014] Furthermore, the camera assembly is connected to a solar power module.

[0015] Beneficial effects: Compared with the prior art, the advantages of this utility model are: the displacement of the top of the chimney is converted into the displacement of the laser point on the plate, which is recorded by the camera component and transmitted to the mobile terminal. The plate uses a scale mark that spreads radially from the center. No calculation is required. The displacement information of the chimney can be obtained directly from the plate information. The structure is simple, the installation is convenient, and the information reading is more intuitive. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0017] Figure 2 This is a schematic diagram of the circular laser information disk of this utility model;

[0018] Figure 3 This is a schematic diagram of the semi-circular laser information disk of this utility model. Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 The chimney top displacement detection system shown includes:

[0021] Laser information disk 1, wherein the laser information disk 1 is located in the top area of ​​the chimney body 2;

[0022] Laser source 3, which is located outside the chimney body 2, emits a laser beam that forms a laser point on the laser information disk 1, and converts the swaying of the chimney into the displacement of the laser point on the laser information disk 1.

[0023] Camera assembly 4 is mounted on the chimney body 2, with its lens facing the surface of the laser information disk 1.

[0024] The laser information disk 1 is a circular or fan-shaped disk structure, with the initial laser point located at the center of the laser information disk 1. The disk surface of the laser information disk 1 faces downward and is vertically fixed to the outer wall of the chimney body 2. The laser source 3 is located at the bottom periphery of the chimney body 2 and emits a laser beam toward the disk surface.

[0025] like Figure 2 As shown, when using a circular disk, only one laser information disk 1 needs to be set up. The initial laser point moves from the center to the surrounding area, and one disk can record the displacement information of the chimney in each direction.

[0026] like Figure 3As shown, when using a semi-circular disk or a fan-shaped disk, two semi-circular disks need to be set up, symmetrically placed on both sides of the chimney, each recording the displacement information of 180° around the chimney. The information from the two disks combined is the complete displacement information.

[0027] The laser information disk 1 has a scale marking that radiates radially from the center. The displacement information of the chimney can be directly read through this marking. A threshold mark can be set on the scale marking. When the laser point exceeds the threshold mark, it will also be displayed intuitively.

[0028] The laser information disk 1 and the laser source 3 are paired up one by one. There may be one or more pairs of laser sources. Considering that the laser source 3 may cause harm to personnel, a fixed platform that exceeds the working height of a person can be erected on the ground, and the laser source 3 can be drilled through the fixed platform.

[0029] The camera assembly 4 is fixed to the outer wall of the chimney body 2, located below the laser information disk 1, corresponding to it one-to-one. The camera assembly 4 is connected to the data transmission module, which transmits the displacement information of the laser points on the laser information disk 1 to the mobile terminal. The computer can use existing image feature capture technology to capture the position of the laser points in each frame of the image, and obtain the displacement curve of the laser points, thus displaying the displacement information of the chimney more intuitively and clearly.

[0030] The camera component 4 is connected to a solar power module, eliminating the need for additional wiring and providing power to the entire system.
