Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety detection, in particular to a boiler safety detection device. Background Art
[0002] As a kind of equipment used in power plants, the main function of power station boilers is to provide steam of specified quantity and quality for steam turbines. The volume of boilers is adjusted according to actual production needs and corresponds to the capacity of the steam turbine generator set. Power station boilers mainly use a variety of fuels such as pulverized coal, crude oil or heavy oil for combustion to achieve power output. However, during long-term use, scaling will gradually appear inside the boiler. These scalings contain insoluble carbonate substances. If they exist for a long time, they will have a certain corrosive effect on the boiler.
[0003] Therefore, staff will conduct internal inspections of the boiler from time to time, usually using photographic equipment to observe the internal corrosion or scaling of the boiler in order to assess its degree or amount. However, most current inspection agencies are of fixed size, making it difficult to inspect boilers of different sizes, which has major limitations. Utility Model Content
[0004] The purpose of the utility model is to provide a boiler safety detection device to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a boiler safety detection device, comprising a main body and a detection head, wherein one end of the main body is fixedly connected to a motor, a threaded rod is provided in the middle of the motor, a slider is sleeved on the threaded rod, and a steering rod is slidably connected to the slider, the detection head is installed on one end of the steering rod, and the other end of the steering rod is fixedly connected to a connecting head.
[0006] Preferably, the upper end of the steering rod is fixedly connected to a support rod, a buffer block is sleeved on the support rod, an elastic member is installed in the buffer block, and the buffer block is fixedly connected to a detection head.
[0007] Preferably, the upper end of the support rod is fixedly connected to a clamping block, and the clamping block is slidably connected to the inner wall of the buffer block.
[0008] Preferably, one side of the steering rod is fixedly connected to a transmission line, and the other end of the transmission line is fixedly connected to a display screen.
[0009] Preferably, a handle is fixedly connected to the bottom end of the main body.
[0010] Preferably, the connecting head is clamped to the extension rod.
[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:
[0012] First, the utility model can extend the detection range of the detection head by setting a steering rod and a clamping block. The motor drives the threaded rod to rotate, which makes the slider rise and fall, and drives the steering rod to move. The device is extended into the boiler, and the movement of the steering rod makes the detection head contact with the inner wall of the boiler for detection. In addition, one end of the connector can be clamped with the extension rod, thereby further extending the steering rod, realizing the detection of boilers of different sizes, and enhancing the practicality of the device.
[0013] Second, the utility model can provide buffer protection for the detection head by arranging elastic parts and buffer blocks. When the detection head is impacted, the buffer block is squeezed, and the impact force is absorbed by squeezing the internal elastic parts through the buffer block, thereby reducing damage to the detection head.

The detection head 2 is installed at one end of the steering rod 6. The other end of the steering rod 6 is fixedly connected to a connecting head 8. The threaded rod 3 is driven to rotate by the motor 14, and the slider 4 is driven to rise and fall by the rotation of the threaded rod 3. The steering rod 6 is driven to move by the lifting of the slider 4. At this time, the device is extended into the boiler, and the detection head 2 is brought into contact with the inner wall of the boiler through the movement of the steering rod 6 for detection, so as to judge the internal situation of the boiler.
[0021] The upper end of the steering rod 6 is fixedly connected to the support rod 11, the support rod 11 is sleeved with a buffer block 7, an elastic member 10 is installed in the buffer block 7, and the buffer block 7 is fixedly connected to the detection head 2. When the detection head 2 is impacted, the buffer block 7 is squeezed, and the impact force is absorbed by squeezing the internal elastic member 10 by the buffer block 7, thereby reducing damage to the detection head 2.
[0022] The upper end of the support rod 11 is fixedly connected to the clamping block 13, and the clamping block 13 is slidably connected to the inner wall of the buffer block 7. The buffer block 7 and the support rod 11 are limited by the clamping block 13 to prevent the buffer block 7 from falling off the support rod 11.
[0023] One side of the steering rod 6 is fixedly connected to the transmission line 12, and the other end of the transmission line 12 is fixedly connected to the display screen 5. The detection result is displayed on the display screen 5, so that the corrosion or scaling of the inner wall of the boiler can be intuitively obtained.
[0024] The bottom end of the main body 1 is fixedly connected to a handle 9, and the handle 9 supports the main body 1.
[0025] The connector 8 is clamped with the extension rod, and one end of the connector 8 can be clamped with the extension rod, thereby extending the steering rod 6 to detect boilers of different sizes, further improving the practicability of the device.
[0026] When in use, the motor 14 drives the threaded rod 3 to rotate, and the rotation of the threaded rod 3 drives the slider 4 to rise and fall, and the lifting of the slider 4 drives the steering rod 6 to move. At this time, the device is extended into the boiler, and the steering rod 6 is moved to make the detection head 2 contact with the inner wall of the boiler for detection. At the same time, when the detection head 2 is impacted, the buffer block 7 is squeezed, and the impact force is absorbed by squeezing the internal elastic member 10 by the buffer block 7, thereby reducing damage to the detection head 2. At the same time, one end of the connecting head 8 can be clamped with the extension rod, thereby extending the steering rod 6, and boilers of different sizes are detected, which further improves the practicality of the device. At the same time, the detection results are displayed on the display screen 5, so that the corrosion or scaling of the inner wall of the boiler can be intuitively obtained.
