Description

Technical Field

[0001] The embodiments of this utility model relate to the field of electrical equipment technology in thermal power plants. More specifically, this utility model relates to a protective device for electrical wiring support in thermal power plants. Background Technology

[0002] The core purpose of a thermal power plant is to generate heat energy by burning fuels (such as coal, oil, and natural gas), and then use this heat energy to produce electricity. In a thermal power plant, fuel is burned in a boiler, heating water into high-temperature, high-pressure steam. For example, in a coal-fired power plant, pulverized coal is fully burned in the boiler furnace, releasing a large amount of heat. This heat is absorbed by the water in the boiler, turning it into steam. The high-temperature, high-pressure steam drives a turbine to rotate, converting heat energy into mechanical energy. The turbine blades rotate at high speed under the impetus of the steam; this rotational motion contains mechanical energy. Finally, the turbine drives a generator to rotate, and the generator converts the mechanical energy into electrical energy. In this way, thermal power plants can continuously convert the chemical energy of fuel into electrical energy, providing electricity to society and meeting electricity demand. With the development of modern society, the demand for electricity is increasing daily.

[0003] During the electrical wiring process in thermal power plants, the electrical connection harnesses are heavy. To prevent the connectors from detaching and causing malfunctions and shutdowns of the power plant machinery, wiring support and protection devices are needed to support and protect the electrical connection harnesses and their connectors during installation. In existing technology, the protection of the connector ends is generally achieved by tightening a screw to move a clamping plate downwards until the clamping plate and a pre-cut groove in the base form a complete clamp. At this point, the connection harness is positioned between the clamping plate and the groove in the base, and the connection harness is clamped by both. While this method achieves the clamping and protection operation, the clamping plate requires support and positioning from the top plate component for installation. During the initial installation and maintenance phases, this clamping plate structure is inconvenient to replace, requiring the removal of the entire top plate structure of the unit, which is not conducive to practical operation.

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

[0024] Figure 1 The structure of a thermal power plant electrical wiring support and protection device 100 according to an embodiment of the present invention is shown. For example... Figure 1 As shown, and in combination Figure 2According to an embodiment of the present invention, a power plant electrical wiring support and protection device 100 includes: a base 1, which is disposed on a fixed foundation; a support frame 2, which is disposed on the base 1, the support frame 2 including: a bottom plate 21 and a top plate 22 arranged in parallel, one side of the bottom plate 21 and the top plate 22 being connected by a vertical plate 23, and the other side of the bottom plate 21 and the top plate 22 opposite to the vertical plate 23 being configured as an opening; a positioning seat 24, which is disposed inside the top plate 22; and a limiting seat 3, the top of which is provided with a detachable connecting assembly 31, the detachable connecting assembly 31 being detachably fixedly connected to the top plate 22. The limiting seat 3 and the positioning seat 24 are mated and engaged, and a fastening cavity 4 adapted to the outer periphery of the connecting wire harness is formed between the limiting seat 3 and the positioning seat 24, the connecting wire harness being placed within the fastening cavity 4.

[0025] In practical use, the electrical wiring support and protection device 100 for thermal power plants according to this embodiment of the present invention involves moving the connecting wire harness through the opening of the support frame 2 into the support frame 2 on the base 1, placing the limiting seat 3 at the bottom of the connecting wire harness, and lifting it upwards to engage with the positioning seat 24, thereby enclosing the connecting wire harness within the engaging cavity 4. The installation of the electrical wiring support and protection device 100 for thermal power plants according to this embodiment of the present invention is completed by fixing the detachable connecting assembly 31 to the top plate 22.

[0026] With the above-described configuration, the power plant electrical wiring support and protection device 100 according to this embodiment of the present invention is connected by the locking seat 3 and the positioning seat 24. The locking seat 3 is installed upwards, providing support for the connecting wire harness. Simultaneously, the detachable connecting component 31 is fixedly engaged with the top plate 22. When maintenance is required, the locking seat 3 can be removed after disassembling the detachable connecting component 31, thus separating the locking seat 3 from the connecting wire harness. This operation does not require disassembling the support frame 2, making the power plant electrical wiring support and protection device 100 according to this embodiment of the present invention more convenient for maintenance operations and improving the ease of manual operation.

[0027] Please refer to Figure 2 and Figure 3 In some embodiments, the limiting seat 3 may be constructed as a groove structure, with plug-in members 32 extending from the two side walls of the groove structure respectively. A connecting through groove 221 for inserting two plug-in members 32 is formed on the top plate 22. Plug-in holes 321 are correspondingly formed on the top of the two plug-in members 32. The detachable connecting assembly 31 includes a fixing member 311 for passing through the two plug-in holes 321. The two ends of the fixing member 311 are fixedly connected to the top plate 22 through connectors 312.

[0028] In this application, the groove structure of the limiting seat 3 can be a U-shaped structure constructed from a plate, with the U-shaped structure facing upwards. A semi-circular groove is formed on the positioning seat 24, which is fastened to the limiting seat 3, and faces downwards, matching the U-shaped structure. The U-shaped structure and the semi-circular groove are fastened together to form a fastening cavity 4. In this application, the connecting slot 221 includes two elongated connecting holes formed on the top plate 22 and arranged in parallel. The distance between the two elongated connecting holes is adapted to the position of the fixing member 311, so that the limiting seat 3 can be inserted into the connecting slot 221 through the fixing member 311. After the fixing member 311 is inserted into the insertion hole 321, the fixing member 311 abuts against the top surface of the top plate 22. After the fixing member 311 is fixed to the top plate 22 by bolts or other connecting parts 312, the limiting seat 3 is fixed. Conversely, the limiting seat 3 can be disassembled. With this setup, the support and maintenance of the connecting harness can be completed simply by removing the bolts and then removing the fixing part 311, making the disassembly and assembly of the limit seat 3 convenient.

[0029] Please refer to Figure 3 In some embodiments, the insertion component 32 may include: two vertical plates 322, which are respectively disposed at both ends of the sidewall of the groove structure; and a horizontal plate 323, which connects the top ends of the two vertical plates 322. Insertion holes 321 are formed on the corresponding vertical plates 322 on both sides, and the fixing component 311 includes two fixing pins 3111.

[0030] In this application, the two ends of the sidewalls of the U-shaped structure are bent outwards to form side plates, and vertical plates 322 are fixedly connected to the side plates. Each of the two plug-in components 32 includes two vertical plates 322, and a horizontal plate 323 is connected to the top of the vertical plates 322. Corresponding vertical plates on the two sidewalls of the U-shaped structure form a set of plug-in components 32, and the four vertical plates 322 form two sets of plug-in components 32. Two fixing pins 3111 are respectively plugged into the two sets of plug-in components 32. In this application, the horizontal plate 323 can be configured as a handle to facilitate the operation of the limiting seat 3.

[0031] Please continue to refer to Figure 2 and Figure 3In some embodiments, two sets of support fixing seats 222 may be provided on the outer side of the top plate 22. The two sets of support fixing seats 222 are respectively provided on both sides of the connecting through groove 221 and are respectively supported and cooperated with the two ends of the two fixing pins 3111. The top surface of the support fixing seat 222 forms a semi-circular placement groove 223 adapted to the fixing pin 3111. The placement groove 223 at one end of the fixing pin 3111 is constructed as a through groove, and the placement groove 223 at the other end of the fixing pin 3111 is constructed as a blind groove. A connecting hole 224 is opened on the inner bottom surface of the placement groove 223. Locking holes 3112 corresponding to the connecting holes 224 are formed at both ends of the fixing pin 3111. The locking holes 3112 and the connecting holes 224 are fixedly connected by fixing bolts.

[0032] In this application, the support fixing base 222 is respectively disposed on both sides of the two connecting through slots 221. There are four sets of support fixing bases 222. The top surface of each support fixing base 222 is provided with a semi-circular placement slot 223. One end of the placement slot 223 of the support fixing base 222 is a through slot, and the other end of the placement slot 223 of the support fixing base 222 is a blind slot. A connecting hole 224 is provided in the middle of the inner bottom surface of the support fixing base 222. A fixing pin 3111 is inserted into the support fixing base 222. Both ends of the fixing pin 3111 are vertically provided with locking holes 3112. The locking holes 3112 and the connecting holes 224 are arranged vertically and vertically. The locking holes 3112 and the connecting holes 224 can both be threaded holes. The locking holes 3112 can also be through holes. The two are fixedly connected by fixing bolts.

[0033] With the above setup, during operation, the connecting harness is placed into the limiting seat 3. The operator lifts the bottom of the limiting seat 3, allowing the upper end of the plug-in component 32 to pass through the connecting through slot 221. The fixing pin 3111 passes through the support fixing seat 222 with the through slot and is inserted into the plug holes 321 on both sides of the plug-in component 32 until the fixing pin 3111 enters the support fixing seat 222 with the blind slot, completing the initial and rapid positioning. By screwing the fixing bolt into the locking hole 3112 and the connecting hole 224, the fixing connection operation of the limiting seat 3 is completed, thereby improving the stability of the connecting harness installation. In addition, the bottom-up installation method allows for easy separation of the limiting seat 3 from the connecting harness by simply removing the fixing pin 3111 and fixing bolt on the top surface during actual operation, making maintenance and repair operations more convenient and improving the ease of manual operation.

[0034] Please refer to Figure 4In some embodiments, the limiting seat 3 may have: a plurality of support ribs 33 disposed on the inner circumferential surface of the limiting seat 3; and / or a plurality of vent holes 34 disposed on the outer circumferential surface of the limiting seat 3, with the vent holes 34 located between adjacent support ribs 33. The plurality of support ribs 33 are arranged in a ring array at intervals along the inner circumferential surface of the limiting seat 3, and the plurality of vent holes 34 are arranged in a ring array.

[0035] In this application, the support rib 33 can be made of a rigid rubber strip. Through this arrangement, the support rib 33 allows for a certain distance between the outer periphery of the bottom of the connecting harness and the limiting seat 3, providing space for heat dissipation and improving the heat dissipation effect of the connecting harness. The vent holes 34 further enhance the heat dissipation effect of the connecting harness.

[0036] In some preferred embodiments, the length of the support rib 33 may be the same as the axial length of the limiting seat 3, so as to provide a more stable support effect for the connecting wire harness.

[0037] Please refer to Figure 5 In some embodiments, the top surface of the support rib 33 located at the bottom side of the support rib 33 is provided with an installation groove 331, and the limiting seat 3 also includes a temperature sensing element 332, which is electrically connected to an external temperature monitoring device and is disposed inside the installation groove 331.

[0038] In this application, the temperature sensing element 332 can be a temperature-sensing optical fiber laid in the mounting groove 331, enabling it to perform real-time temperature measurement of the connecting wire harness. In this application, the temperature sensing element 332 is disposed within the bottommost support rib 33, but it can also be disposed in other locations. It is preferred to be disposed within the bottommost support rib 33, which facilitates better support of the connecting wire harness and real-time temperature measurement.

[0039] Please return Figure 4 In some embodiments, the inner top surface of the positioning seat 24 may be provided with anti-slip ribs 241, and multiple anti-slip ribs 241 are arranged at intervals. The anti-slip ribs 241 are used to abut against the outer peripheral surface of the connecting wire harness.

[0040] In this application, the anti-slip ribs 241 help to increase the friction between the ribs and the connecting wire harness, thereby improving the stability of the connecting wire harness.

[0041] Preferably, in one embodiment, the limiting seat 3 is made entirely of aluminum alloy, so that the limiting seat 3 has the characteristics of being lightweight and high-strength.

[0042] Please return Figure 2In some embodiments, the support frame 2 may further include an auxiliary support device 25, comprising: an auxiliary connecting member 251 connected to one side of the base plate 21 and extending outward; and a plurality of auxiliary brackets 252 spaced apart on the top of the auxiliary connecting member 251, the auxiliary brackets 252 being constructed as a semi-circular structure with an upward opening. The auxiliary brackets 252 are used to form a support with external connecting harnesses.

[0043] In this application, the auxiliary connecting component 251 can be constructed as an auxiliary connecting rod extending outward from one side of the base plate 21. Auxiliary brackets 252 are spaced apart at the top of the auxiliary connecting rod. The auxiliary brackets 252 are supported and connected to the external connecting harness. This configuration reduces the weight pull on the connection point of the connecting harness, further improving the stability of the connecting harness during use.

[0044] Please refer to Figure 2 and Figure 5 In some embodiments, the support frame 2 further includes a monitoring auxiliary component, which includes: a contact sensor 26, which is disposed on the base plate 21 and located in the middle region between the limiting seat 3 and the auxiliary frame, and the height of the contact sensor 26 is lower than the vertical height of the connecting wire harness in the limiting seat 3 and the auxiliary frame; and / or, a dehumidification component 27, which includes a placement frame 271 and a desiccant pack 272, the placement frame 271 being disposed on the inner side of the upright plate 23, and the desiccant pack 272 being disposed in the placement frame 271.

[0045] In this application, by setting the contact sensor 26, if the limit seat 3 moves downward during use, the connecting harness will come into contact with the contact sensor 26 below, causing the contact sensor 26 to emit an electrical signal to prompt manual maintenance, thus improving the stability of the connecting harness and providing early warning. In this application, the desiccant pack 272 is placed in the placement frame 271. The desiccant pack 272 can absorb moisture at the joints of the connecting harness, ensuring the connecting harness remains dry.

[0046] Please return Figure 1 and Figure 2 In some embodiments, a protective cover 5 may also be included, which is disposed on the outer side of the top plate 22, and the limiting seat 3 and the detachable connecting assembly 31 are both located inside the protective cover 5.

[0047] With this setup, the protective cover 5 can shield the top surface of the top plate 22, thereby protecting the mounting structure on the top surface and extending the service life of the limit seat 3 and the detachable connection assembly 31.

[0048] Please return Figure 1In some embodiments, the electrical wiring support and protection device 100 for thermal power plants of this utility model may include a base 1 and two sets of support frames 2, limit seats 3, and protective covers 5 arranged opposite to each other.
