Description

Technical Field

[0001] This utility model relates to the field of thermal instrumentation technology, and in particular to a power plant thermal instrument that is easy to clean. Background Technology

[0002] A combined heat and power (CHP) plant is a thermal power plant that generates electricity while simultaneously using steam extracted or exhausted from a steam turbine to provide heat to users. Its main working principle is to use the hot water generated after the thermal power plant generates electricity, and then reheat it for heating. In order to ensure the normal operation of the generator units in a timely manner, thermal instruments are needed to monitor various data during power generation. Thermal instruments mainly include: pressure gauges, pressure transmitters, differential pressure transmitters, pressure calibrators, thermal signal calibrators, etc.

[0003] Because thermal instruments generate heat to varying degrees during use, their casings are typically equipped with various shaped heat dissipation vents to ensure timely heat dissipation. However, these vents allow external dust to enter the instrument, necessitating the installation of dust filters inside. Over time, these filters become clogged with dust, reducing internal heat dissipation efficiency. Current dust filters are bolted to the instrument, making disassembly inconvenient and affecting cleaning efficiency. Furthermore, the instrument is installed using multiple mounting plates at the bottom, but these plates are fixed in position. Any misalignment between the holes on the mounting surface and the holes on the mounting plates during installation can hinder proper installation. Therefore, this invention proposes a power plant thermal instrument that facilitates dust removal. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a power plant thermal instrument that is easy to clean.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5As shown, a power plant thermal instrument that is easy to clean includes an instrument body 1. An air inlet 2 and an air outlet 3 are respectively opened on both sides of the instrument body 1. A rotatable dustproof component 4 is provided inside the air inlet 2. A fixing component 6 for fixing the dustproof component 4 is installed on the upper surface of the instrument body 1 and near the air inlet 2. A heat dissipation component 5 is installed on the outer wall of the instrument body 1 and near the air outlet 3. T-shaped guide rails 8 are fixed on the bottom of both sides of the instrument body 1. Multiple mounting components 9 are slidably connected to the surface of the T-shaped guide rails 8.

[0025] Multiple metal heat sinks 7 are fixed through and fixed to the top wall of the instrument body 1.

[0026] The heat dissipation fins 7 can conduct heat out of the instrument body 1, providing another way to dissipate heat from the instrument body 1, thereby improving the heat dissipation effect of the instrument body 1.

[0027] The dustproof component 4 includes a frame plate 41 located inside the air inlet 2. The bottom end of the frame plate 41 is rotatably connected to the bottom end of the air inlet 2 via a hinge. A first dustproof net 42 is fixed inside the frame plate 41, and a handle 43 is fixed on the top surface of the frame plate 41.

[0028] When the frame plate 41 is located inside the air inlet 2, it can prevent external dust from entering the instrument body 1 through the first dustproof net 42.

[0029] A magnet 44 is fixed to the top of the frame plate 41 on the side away from the handle 43, and an iron plate is provided on the top of the air inlet 2. The top of the frame plate 41 is attracted and fixed to the top of the air inlet 2 by the magnet 44.

[0030] By using handle 43, the top of frame plate 41 can be pulled outwards towards air inlet 2, allowing the first dust filter 42 to rotate out from inside air inlet 2, thus facilitating the cleaning of dust on the first dust filter 42. After cleaning, rotate frame plate 41 upwards, and use magnet 44 to attract iron sheets to achieve initial fixation of frame plate 41.

[0031] The fixing component 6 includes a guide rod 61 fixed to the upper surface of the instrument body 1, and an L-shaped clamping plate 62 is slidably connected to the surface of the guide rod 61. A top plate 63 is fixed to the top of the guide rod 61. A spring 64 is fixedly connected to the lower surface of the top plate 63 and the upper surface of the L-shaped clamping plate 62. The vertical part of the L-shaped clamping plate 62 is engaged with the top surface of the frame plate 41.

[0032] Under the push of spring 64, the L-shaped clamping plate 62 will be pressed downward, so the vertical part of the L-shaped clamping plate 62 can be locked onto the top edge of the frame plate 41, thereby further fixing the frame plate 41. When it is necessary to rotate and open the frame plate 41, simply pull the L-shaped clamping plate 62 upward to disengage it from the frame plate 41.

[0033] The heat dissipation assembly 5 includes an annular plate 51 fixed to the outside of the air outlet 3, and an electric fan 52 is fixedly installed inside the annular plate 51. A side cover 53 is rotatably connected to the outer wall of the annular plate 51 by a thread, and a second dustproof mesh 54 is fixedly connected inside the side cover 53.

[0034] During normal heat dissipation, the electric fan 52 is activated, and external air enters the instrument body 1 through the air inlet 2 and is then exhausted through the air outlet 3, thus dissipating heat from the inside of the instrument body 1. The second dust filter 54 prevents external dust from entering the instrument body 1 through the air outlet 3. When it is necessary to clean the second dust filter 54, simply unscrew the side cover 53 from the surface of the annular plate 51.

[0035] Mounting assembly 9 includes a slide block 91 that is slidably sleeved on the surface of T-shaped guide rail 8. The side wall of slide block 91 is threaded with locking bolts 92. Mounting plate 93 is fixed at the bottom of slide block 91, and mounting hole 94 is provided in the middle of mounting plate 93.

[0036] When installing the instrument body 1, the slide 91 can be moved along the T-shaped guide rail 8 so that the mounting hole 94 on the mounting plate 93 at the bottom of the slide 91 is aligned with the mounting hole. Then, tighten the locking bolt 92 to fix the slide 91.

[0037] Working principle: When the instrument body 1 is working normally, the electric fan 52 starts, and external air enters the instrument body 1 through the air inlet 2 and is then discharged through the air outlet 3, thus achieving heat dissipation inside the instrument body 1. When it is necessary to clean the dust on the first dust filter 42, first pull the L-shaped clip 62 upward to disengage it from the frame plate 41, and then rotate the frame plate 41 downward to open it, thereby cleaning the first dust filter 42 in the middle of the frame plate 41. When it is necessary to clean the second dust filter 54, simply unscrew the side cover 53 from the annular plate 51.
