Description

Technical Field

[0001] This utility model relates to the field of thermal power plant technology, specifically to an automated calibration device for instruments in thermal power plants. Background Technology

[0002] A combined heat and power (CHP) power plant is a facility that converts the heat energy generated by fuel combustion into both electrical and thermal energy. Compared with traditional power plants (which only generate electricity) or boiler rooms (which only provide heat), CHP plants achieve cascaded utilization of energy through CHP technology, significantly improving energy efficiency. CHP plants typically use fuels such as coal, natural gas, and biomass, which are burned in boilers to produce high-temperature, high-pressure steam.

[0003] Regarding the above and existing related technologies: When used in thermal power plants, various instruments need to be installed on various equipment. During the use of these instruments, they need to be calibrated, which requires the use of temperature monitoring instruments. However, most calibration equipment lacks dedicated moving and supporting mechanisms, which can easily lead to inconvenience in calibration operations. Therefore, this paper proposes an automated calibration device for instruments in thermal power plants to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An automated calibration device for instruments in a thermal power plant, comprising a vehicle body, a temperature monitoring instrument, and a support device. A bracket is fixedly connected to the upper surface of the vehicle body, and a push handle is also fixedly connected to the upper surface of the vehicle body. The temperature monitoring instrument is located on the inner surface of the bracket. The surface of the bracket is provided with multiple support devices, each including two support plates. The bottom ends of the two support plates are fixedly connected to the surface of the bracket. A movable plate is slidably connected to the inner walls of the two support plates. Two connecting plates are fixedly connected to the surface of the bracket near the two support plates. Magnetic strips are fixedly connected to the side walls of the connecting plates. The side walls of the magnetic strips and the side walls of the movable plates are magnetically attracted to each other. The temperature monitoring instrument is located on the upper surface of the movable plate. The movable plate slides on the inner wall of the support plate, and the movable plate adheres to the magnetic strips on the connecting plates. The magnetic strips attract the movable plate. By setting up the support plates, movable plates, connecting plates, and magnetic strips, the temperature monitoring instrument can be supported, and its position can be easily moved when needed.

[0006] Preferably, two locking blocks are fixedly connected to the upper surface of the movable plate. The two locking blocks are located on the surface of the temperature monitoring instrument. When the temperature monitoring instrument is placed, the temperature monitoring instrument fits against the locking blocks, and the locking blocks can restrict the position of the temperature monitoring instrument to a certain extent.

[0007] Preferably, the bottom end of the movable plate is rotatably connected to multiple support wheels. When the movable plate moves, the movable plate drives the support wheels to roll on the surface of the support frame. By setting the support wheels, the movable plate can be supported.

[0008] Preferably, the surface of the temperature monitoring instrument is fitted with a limit frame, and the inner wall of the limit frame and the moving plate is threaded with two positioning pins. By rotating the positioning pins to the inner wall of the limit frame and the moving plate, the position of the temperature monitoring instrument can be restricted by setting the limit frame and positioning pins.

[0009] Preferably, the surface of the support plate is provided with a sliding groove, and the surface of the movable plate and the inner wall of the sliding groove of the support plate are slidably connected. When the movable plate moves, the movable plate slides on the inner wall of the sliding groove, and the opening of the sliding groove can facilitate the movement of the movable plate.

[0010] Preferably, both sides of the push handle are provided with blocking devices. The blocking device includes a fixed plate, the side wall of the fixed plate is fixedly connected to the side wall of the push handle, and a rotating plate is rotatably connected to the inner wall of the fixed plate. The rotating plate and the inner wall of the vehicle body are threadedly connected with two limiting pins. By rotating the limiting pins to the inner wall of the rotating plate and the vehicle body, the position of other tools on the vehicle body can be restricted by setting the fixed plate, the rotating plate and the limiting pins.

[0011] Preferably, the surface of the rotating plate is fixedly connected with multiple stops, and the surface of the fixed plate is provided with a rotating hole. The inner wall of the rotating hole of the fixed plate is rotatably connected to the surface of the rotating plate. When the rotating plate rotates, it will also drive the stops to rotate. The setting of the stops can restrict the position of other tools.

[0012] The advantages of this utility model are:

[0013] 1. When inspection is required, the temperature monitoring instrument and other calibration devices are placed sequentially on different moving plate surfaces. When the temperature monitoring instrument is placed, it will fit against the locking block. Then, the limiting frame is pushed to fit against the surface of the temperature monitoring instrument. The positioning pin is then rotated to the inner wall of the limiting frame and the moving plate. When the temperature monitoring instrument needs to be used, the moving plate is pushed to slide on the inner wall of the groove of the support plate. The moving plate will drive the temperature monitoring instrument to move. The moving plate will fit against the magnetic strip on the connecting plate. Then, the temperature monitoring instrument is used. When the moving plate moves, it will drive the support wheel to roll on the support surface. By setting the entire device, the inspection equipment can be supported. At the same time, the inspection equipment can be moved out of the support when needed, thereby reducing the obstruction of equipment use due to limited space.

[0014] 2. When it is necessary to place large equipment, the equipment is placed on the upper surface of the vehicle body. Then, the rotating plate is pushed to rotate through the rotating hole on the inner wall of the fixed plate. The rotating plate rotates to the surface of the vehicle body. Then, the limiting pin is rotated to the rotating plate and the inner wall of the vehicle body. When the rotating plate rotates, it will drive the stop block to move. By setting the entire device, the movement of large equipment can be reduced, thereby reducing the possibility of large equipment falling off the surface of the vehicle body.

A magnetic strip 44 is fixedly connected to the side wall of plate 3. The side wall of the magnetic strip 44 and the side wall of the moving plate 42 are magnetically attracted to each other. The temperature detector 5 is located on the upper surface of the moving plate 42. During operation, the temperature detector 5 is placed on the moving plate 42, and then the moving plate 42 is pushed to move the temperature detector 5. The moving plate 42 slides on the inner wall of the support plate 41. The moving plate 42 is in contact with the magnetic strip 44 on the connecting plate 43. The magnetic strip 44 attracts the moving plate 42. By setting the support plate 41, the moving plate 42, the connecting plate 43 and the magnetic strip 44, the temperature detector 5 can be supported. At the same time, the position of the temperature detector 5 can be easily moved when needed.

[0024] Two locking blocks 45 are fixedly connected to the upper surface of the moving plate 42. The two locking blocks 45 are located on the surface of the temperature monitoring instrument 5. During operation, the temperature monitoring instrument 5 is in contact with the locking blocks 45, and the locking blocks 45 can restrict the position of the temperature monitoring instrument 5 to a certain extent.

[0025] The bottom end of the movable plate 42 is rotatably connected to multiple support wheels 46; during operation, the movable plate 42 drives the support wheels 46 to roll on the surface of the bracket 2, and the support wheels 46 can support the movable plate 42.

[0026] The surface of the temperature monitoring instrument 5 is fitted with a limiting frame 47, and the inner wall of the limiting frame 47 and the moving plate 42 are threadedly connected with two positioning pins 48. During operation, the limiting frame 47 is pushed to fit on the surface of the temperature monitoring instrument 5, and then the positioning pins 48 are rotated to the inner wall of the limiting frame 47 and the moving plate 42. By setting the limiting frame 47 and the positioning pins 48, the position of the temperature monitoring instrument 5 can be restricted.

[0027] The surface of the support plate 41 is provided with a sliding groove 49, and the surface of the movable plate 42 is slidably connected to the inner wall of the sliding groove 49 of the support plate 41. During operation, the movable plate 42 slides on the inner wall of the sliding groove 49, and the opening of the sliding groove 49 facilitates the movement of the movable plate 42.

[0028] Both sides of the push handle 3 are provided with blocking devices 6. The blocking device 6 includes a fixed plate 61. The side wall of the fixed plate 61 is fixedly connected to the side wall of the push handle 3. The inner wall of the fixed plate 61 is rotatably connected to a rotating plate 62.

The moving plate 42 will drive the temperature detector 5 to move, and the moving plate 42 will adhere to the magnetic strip 44 on the connecting plate 43. Then, when the temperature detector 5 is used, the movement of the moving plate 42 will drive the temperature detector 5 to move. The support wheel 46 rolls on the surface of the bracket 2. By setting up the entire device, the inspection equipment can be supported, and the inspection equipment can also be moved out of the bracket 2 when needed, thereby reducing the obstruction of equipment use due to the limited space. When it is necessary to place larger equipment, the equipment is placed on the upper surface of the vehicle body 1, and then the rotating plate 62 is pushed to rotate through the rotating hole 65 on the inner wall of the fixed plate 61. The rotating plate 62 rotates to the surface of the vehicle body 1, and then the limiting pin 63 is rotated to the rotating plate 62 and the inner wall of the vehicle body 1. When the rotating plate 62 rotates, it will drive the stop block 64 to move. By setting up the entire device, the movement of larger equipment can be reduced, thereby reducing the possibility of larger equipment falling off the surface of the vehicle body 1.
