[0026] The present invention provides the following embodiments

[0027] Example 1

[0028] See also Figure 1 The figure shows a quick-detachable electrical detection device for a thermal power plant, comprising a detection body 1, with connecting blocks 2 and movable blocks 4 symmetrically distributed at both ends of the detection body 1, the movable block 4 being movable up and down on the outside of the connecting block 2, a second mounting rod 14, a first mounting rod 10 and a main rod 5 being arranged inside the detection body 1, a central cross bar 6 being installed inside the detection body 1, a spring 11 being installed on one side of the central cross bar 6, and a tension spring 13 being arranged on the side of the central cross bar 6 away from the spring 11.

[0029] See also Figure 2-4 In the figure, the main rod 5 is arranged in the middle of the first mounting rod 10, one end of the main rod 5 is fixedly connected to the second mounting rod 14, the other end of the main rod 5 is fixedly connected to the first mounting rod 10, and the main rod 5 is slidably connected to the central cross rod 6.

[0030] In the present embodiment: by arranging the connection block 2 and the movable block 4 to be symmetrically distributed at both ends of the detection body 1, and the movable block 4 can be raised and lowered to a certain extent, after the detection body 1 is normally fixed to the wall using the expansion bolts, the conventional detection body 1 often needs to be removed before the bolts can be disassembled, while this device can drive the second mounting rod 14 and the first mounting rod 10 to move downward by moving the main rod 5 downward, thereby driving the movable block 4 to move downward, so that the connection block 2 and the movable block 4 are away from the expansion bolts, so that the detection body 1 can be quickly disassembled.

[0031] By setting up the second mounting rod 14, the first mounting rod 10 and the main rod 5 for use in conjunction, an I-shaped frame is formed, so that the frame can move upward by itself under the action of the spring 11 and the first mounting rod 10, thereby driving the movable block 4 to move upward to approach the connecting block 2 to tighten the bolts, so as to facilitate the installation of the detection body 1.

[0032] Example 2

[0033] See also Figure 1 This embodiment further explains Example 1. In the figure, one side of the connecting block 2 is fixedly connected to the outer shell of the detection body 1. The surfaces of the connecting block 2 and the movable block 4 are both provided with arc surfaces. The connecting block 2 and the movable block 4 are distributed at the four corners of the detection body 1.

[0034] In this embodiment: by arranging the connecting blocks 2 and the movable blocks 4 distributed at the four corners of the detection body 1, the user can bolt and fix the four corners of the detection body 1 to obtain better hanging stability. By arranging the connecting blocks 2 and the detection body 1 for use in coordination, the connecting blocks 2 can be fixed to the detection body 1 to ensure the connection strength of the connecting blocks 2.

[0035] See also Figure 2 In the figure, the surface of the central cross bar 6 is fixedly connected to the detection body 1 , the central cross bar 6 is arranged in the middle of the detection body 1 , and the spring 11 and the tension spring 13 are both bolted to the central cross bar 6 .

[0036] In this embodiment: by setting the central cross bar 6 for use with the detection body 1, the central cross bar 6 can be fixed on the back of the detection body 1, and the spring 11 is set to provide an upward elastic force to the second mounting rod 14, and the tension spring 13 is set to provide an upward pulling force to the first mounting rod 10, so that the first mounting rod 10 and the second mounting rod 14 can drive the movable block 4 to move upward by itself.

[0037] See also Figure 3In the figure, the movable block 4 is distributed at both ends of the second mounting rod 14, and the movable block 4 is distributed at both ends of the first mounting rod 10. The second mounting rod 14 and the first mounting rod 10 are both bolted to the movable block 4, the lower side of the second mounting rod 14 is bolted to the spring 11, and the upper side of the first mounting rod 10 is bolted to the tension spring 13.

[0038] In this embodiment: by setting the cooperation of the second mounting rod 14, the first mounting rod 10 and the movable block 4, the movable block 4, the first mounting rod 10, the main rod 5 and the second mounting rod 14 can form a whole to move together, and the movable block 4 can be disassembled for easy installation and later replacement.

[0039] See also Figure 3 In the figure, the arc surfaces of the connecting block 2 and the gasket 3 are both provided with gaskets 3, the back of the detection body 1 is bolted with a back cover 15, and side grooves 12 are opened on both sides of the detection body 1.

[0040] In this embodiment: a back cover 15 is provided to seal the back of the detection body 1, and the back cover 15 can be disassembled to facilitate the later inspection of the back parts of the detection body 1, and a protrusion is fixedly connected to the end of the movable block 4 close to the detection body 1, which is used to engage in the side groove 12 to limit the movement of the movable block 4, and the gasket 3 can be coated with corrosion-resistant materials to prevent rust from long-term contact with the expansion bolt. In order to prevent metal products from rusting due to environmental factors during use, especially when the expansion bolt is installed in a humid or dusty environment, a rust-resistant gasket is usually used between the expansion bolt and other components. The rust-resistant gasket can protect the screw head of the expansion bolt from corrosion and extend its service life; the gasket can also help to evenly distribute the pressure to prevent damage or loosening caused by concentrated pressure; by providing a flat and non-deformable surface, the gasket can increase the stability of the entire fastening system. The gasket can be made of stainless steel, galvanized steel or other materials with anti-corrosion properties.

[0041] See also Figure 4 In the figure, the upper end of the main rod 5 is hollow, and a resistance rod 9 is inserted into the upper end of the main rod 5. The resistance rod 9 passes through the outer shell on the upper side of the detection body 1. A limiting block 8 is provided at the upper end of the detection body 1. A rotating handle 7 is fixedly connected to the upper end of the resistance rod 9, and the rotating handle 7 and the limiting block 8 are movably connected.

[0042] In this embodiment: by setting the resistance rod 9, when the main rod 5 needs to be moved downward, the resistance rod 9 can be connected with the main rod 5 and pressed to drive the main rod 5, the second mounting rod 14 and the first mounting rod 10 to move downward, and then control the movable block 4 and the connecting block 2 to move away, and when the rotating handle 7 is overlapped with the L-shaped limiting block 8, the second mounting rod 14, the first mounting rod 10 and the main rod 5 can be limited to keep the movable block 4 in the descending position, so as to facilitate the removal of the detection body 1 during disassembly.

[0043] The specific implementation process of the present invention is as follows: when the electrical detection device needs to be disassembled, first, the main rod 5 is connected through the contact rod 9, and the contact rod 9 is pressed to make the main rod 5 drive the second installation rod 14 and the first installation rod 10 to move downward, so that the movable block 4 moves downward and away from the connecting block 2, so that a gap is formed between the movable block 4 and the connecting block 2, and it can be removed from the expansion screw, and the second installation rod 14, the first installation rod 10 and the main rod 5 are limited by rotating the handle 7 to ensure that there is always a gap between the movable block 4 and the expansion screw, which is convenient for disassembly of the detection device. The spring 11 provides an upward elastic force to the second mounting rod 14, and the tension spring 13 provides an upward pulling force to the first mounting rod 10, so that the first mounting rod 10 and the second mounting rod 14 drive the movable block 4 to move upward by itself, so that the movable block 4 returns to its original position, ensuring that the movable block 4 and the connecting block 2 are in contact with the expansion screw. Gaskets 3 are arranged on the movable block 4 and the connecting block 2. The gasket 3 is coated with corrosion-resistant material to prevent rust caused by long-term contact with the expansion bolt, thereby ensuring the stability of the connection with the expansion screw.

[0044] The beneficial effects of the present invention are as follows: a quick-detachable thermal power plant electrical detection device is provided, which solves the problem that the thermal power plant electrical detection device is not quickly disassembled, and comprises a detection body, wherein connecting blocks and movable blocks are symmetrically distributed at both ends of the detection body, and the movable block is lifted and lowered on the outside of the connecting block, and the detection body is provided with a second mounting rod, a first mounting rod and a main rod inside, and a central cross bar is installed inside the detection body, and a spring is installed on one side of the central cross bar, and by arranging the connecting blocks and the movable blocks to be symmetrically distributed at both ends of the detection body, and the movable block can be lifted and lowered to a certain extent, this device can drive the second mounting rod and the first mounting rod to move downward by moving the main rod downward, and then drive the movable block to move downward, so that the connecting block and the movable block are away from the expansion bolt, and then the detection body can be quickly dismantled;

[0045] The invention solves the problem that currently some small-volume detection devices are generally installed by wall-mounting, which usually uses expansion bolts for fixing and installation, but this fixing method is relatively rigid and not conducive to the later disassembly and maintenance of the electrical detection devices of thermal power plants. The rear cover is designed to be detachable, and the rear cover can be disassembled when necessary to facilitate the later inspection of the back parts of the detection body, making the disassembly of the detection device faster and the maintenance and repair more convenient.
