Description

Technical Field

[0001] This utility model relates to the field of thermal instrument fault alarm technology, and in particular to a thermal instrument fault alarm that is easy to repair. Background Technology

[0002] A power plant, often simply called a power plant, is a factory that converts various primary energy sources (such as hydropower, coal, oil, natural gas, nuclear energy, wind power, solar energy, etc.) into electrical energy. Existing power plants require the use of thermal instruments to measure, control, and monitor physical quantities such as temperature, pressure, flow rate, and liquid level during thermal processes.

[0003] Most existing thermal instruments have alarm devices installed on their tops. These alarm devices are usually fixed with screws during installation. Screws are used to fix the alarm device to the top of the thermal instrument and make an electrical connection between the alarm device and the thermal instrument to ensure that the alarm device can issue an alarm at the first time when the instrument data is abnormal.

[0004] Based on the aforementioned technologies, the applicant believes that using screws for installation and fixing is not conducive to the maintenance of fault alarms. During maintenance, tools are needed to remove the alarms, which is inconvenient in practice. In response to the above problems, we have introduced a thermal instrument fault alarm that is easy to maintain. Utility Model Content

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The present invention discloses a thermal instrument fault alarm that is easy to inspect and repair, which is mainly used in the scenario of inspecting and repairing thermal instrument fault alarms.

[0030] Reference Figure 1 - Figure 5 A fault alarm for thermal instruments that is easy to maintain includes an instrument housing 1. A mounting base 2 is fixedly connected to the outside of the instrument housing 1. A mounting column 5 is movably connected to the top of the mounting base 2. An alarm component 3 is fixedly connected to the top of the mounting column 5. An alarm light 4 is fixedly connected to the top of the alarm component 3. An installation mechanism is provided inside the mounting base 2. The installation mechanism includes a slide rail 61, which is fixedly connected inside the mounting base 2. Sliding blocks 62 are symmetrically slidably connected to the outside of the slide rail 61. A connecting frame 63 is fixedly connected to the top of each of the two sliding blocks 62. A positioning ring 64 is fixedly connected to the top of each of the two connecting frames 63. A sliding column 65 is slidably connected to the bottom of the inner wall of the mounting base 2. A spring 66 is sleeved on the outside of the sliding column 65. A connecting plate 67 is fixedly connected to the bottom of the sliding column 65. A lifting plate 68 is fixedly connected to the top of the sliding column 65. A diagonal support plate 69 is symmetrically rotatably connected to the front of the lifting plate 68. The diagonal support plate 69 is rotatably connected to the sliding block 62. The outer side of the mounting column 5 is symmetrically provided with positioning slots 610, which are used in conjunction with the positioning ring 64.

[0031] In this embodiment: The connecting plate 67 is supported upwards. The upward movement of the connecting plate 67 causes the sliding column 65 to slide upwards, which in turn causes the lifting plate 68 to move upwards. The upward movement of the lifting plate 68 causes the tops of the two inclined support plates 69 to move away from each other, which in turn causes the two sliding blocks 62 to slide away from each other on the outside of the slide rail 61. Then, the two connecting frames 63 move away from each other, and the two connecting frames 63 cause the two positioning rings 64 to move out of the positioning slot 610. Then, the operator pulls the mounting column 5 upwards and pulls the mounting column 5 out of the mounting base 2. Through the set installation mechanism, the alarm can be quickly disassembled and installed. No external tools are needed during the installation and disassembly process, making the operation simpler and improving the efficiency of installation and disassembly. The structure is simple and highly practical.

[0032] In the above technical solution, considering that using screws for installation and fixing is not conducive to the maintenance of the fault alarm, and that tools are needed to remove the alarm during maintenance, the specific operation is as follows:

[0033] Reference Figure 1 - Figure 5In a preferred embodiment, a limiting plate 7 is fixedly connected to the outer side of the mounting post 5. A liquid crystal display screen 9 is fixedly connected to the front of the instrument housing 1, and a protective cover 10 is fixedly connected to the front of the instrument housing 1 and above the liquid crystal display screen 9. A heat dissipation groove 8 is fixedly connected to the bottom of the instrument housing 1. A connecting seat 11 is fixedly connected to the interior of the mounting base 2, below the mounting post 5.

[0034] In this embodiment: the limiting plate 7 can limit the installation column 5 and position the insertion depth of the installation column 5; the LCD screen 9 can display the data intuitively; the protective cover 10 can protect the LCD screen 9; the heat dissipation groove 8 can dissipate heat from the instrument; and the connecting seat 11, with electrical connectors at both the top and bottom of the installation column 5, can electrically connect the alarm and the instrument.

[0035] Working principle: When the fault alarm needs to be disassembled for maintenance, the worker supports the connecting plate 67 upwards. The connecting plate 67 moves upwards, causing the sliding column 65 to slide upwards, which in turn moves the lifting plate 68 upwards. The upward movement of the lifting plate 68 causes the tops of the two inclined support plates 69 to move away from each other, which in turn causes the two sliding blocks 62 to slide away from each other on the outside of the slide rail 61. Then, the two connecting frames 63 move away from each other, which in turn causes the two positioning rings 64 to move out of the positioning slot 610. Then, the worker pulls the mounting column 5 upwards and removes it from the mounting base 2 to inspect the alarm component 3 and the alarm light 4.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
