Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, in particular to a cooling device that is convenient for disassembly, assembly and maintenance of a fire extinguishing system. Background Art

[0002] In the field of rail transit, electrical equipment will generate a lot of heat when working for a long time during locomotive operation. There is also the risk of fire caused by line short circuit, equipment failure, etc.

[0003] The structural design of traditional locomotive fire protection systems in the existing technology is unreasonable. Most of them adopt an integral structure, and the components are interconnected, which requires overall disassembly for maintenance. The operation is difficult and time-consuming. In particular, core components such as fire extinguisher tanks lack a quick positioning and installation structure, and the alignment needs to be repeatedly adjusted during replacement, which seriously affects maintenance efficiency. In addition, space utilization is low, and the space in the locomotive equipment compartment is small. However, the piping layout of the traditional fire extinguishing system is chaotic, and the electrical control unit occupies a large space, which often interferes with the heat dissipation system. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a cooling device that is easy to disassemble and maintain the fire extinguishing system, solving the technical problems of unreasonable structural design and low space utilization of the locomotive fire extinguishing system in the existing technology. It has the advantages of greatly reducing the difficulty and workload of subsequent maintenance and high space utilization.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a cooling device for a fire extinguishing system that is easy to disassemble and maintain, comprising a mounting frame, an aluminum top cover fixedly mounted on the upper end of the mounting frame, an inspection door assembly provided on the mounting frame, a centrifugal fan for discharging heat fixedly mounted inside the mounting frame, radiators symmetrically arranged on both sides of the centrifugal fan, an active fire extinguishing mechanism detachably mounted inside the mounting frame, a fire extinguishing cabinet and a sensor provided in the locomotive compartment, and an active fire extinguishing mechanism that is automatically activated when the sensor detects an open fire or excessively high temperature in the compartment. The fire extinguishing mechanism will automatically input fire extinguishing gas into the fire extinguishing cabinet to extinguish the fire. The active fire extinguishing mechanism includes a fire extinguishing tank assembly, a diversion pipeline assembly and an electrical control assembly. The fire extinguishing tank assembly includes a fire extinguishing tank body and a fire extinguishing tank bracket. The fire extinguishing tank bracket is provided with a limit clamp for fixing the fire extinguishing tank body. The fire extinguishing tank body is connected to the main fire extinguishing pipeline. The fire extinguishing tank bracket is provided with an anti-detachment structure that supports the fire extinguishing tank body. The fire extinguishing tank assembly, the diversion pipeline assembly and the electrical control assembly adopt a modular design and can be disassembled and repaired separately, which is convenient for later maintenance.

[0006] Preferably, a mounting seat A for mounting the fire extinguishing tank assembly is welded inside the mounting frame, and a limit plate is fixedly mounted on the mounting seat A. When the fire extinguishing tank assembly falls on the limit plate, the mounting holes can be quickly aligned, thereby reducing installation time.

[0007] Preferably, the anti-fall-off structure is fixedly mounted on the bottom of the fire extinguisher tank bracket and is used to clamp the fire extinguisher tank body, thereby effectively preventing the fire extinguisher tank body from falling off during the hoisting process.

[0008] Preferably, a lifting circular hole is provided on the fire extinguisher tank bracket, and the fire extinguisher tank assembly can be lifted in or out from the inside of the mounting frame through the lifting circular hole, so as to facilitate maintenance operations.

[0009] Preferably, the radiator is fixedly connected to the mounting frame, and the radiator and the centrifugal fan are sealed by a sealing strip. When the centrifugal fan is powered on, the heat generated by the operation of various components in the locomotive can be discharged through the radiator in time, thereby achieving a cooling effect.

[0010] Preferably, the diversion pipeline assembly includes a mounting base B welded to the inside of the mounting frame, and a solenoid valve mounting plate is detachably mounted on the mounting base B, and a branch fire extinguishing pipeline is fixedly mounted on the solenoid valve mounting plate. The branch fire extinguishing pipeline is connected to the main fire extinguishing pipeline. After the fire extinguishing gas inside the fire extinguishing tank body is discharged through the main fire extinguishing pipeline, it will enter each fire extinguishing cabinet through the branch fire extinguishing pipeline.

[0011] Preferably, the branch fire extinguishing pipeline is composed of six exhaust pipes, each exhaust pipe is equipped with an electromagnetic reversing valve to control the on and off of the exhaust pipe, and each exhaust pipe corresponds to a fire extinguishing cabinet in a locomotive, thereby realizing independent operation and precise fire extinguishing.

[0012] Preferably, the six exhaust pipes are symmetrically arranged on the upper and lower sides of the solenoid valve mounting plate, which can fully utilize the narrow space inside the mounting frame.

[0013] By means of the above technical solution, the present invention provides a cooling device for a fire extinguishing system that is easy to disassemble, assemble, and maintain, and has at least the following beneficial effects: 1. The present invention adopts a modular design by setting an active fire extinguishing mechanism, and the fire extinguisher tank assembly, diversion pipeline assembly and electrical control assembly are designed. The lifting circular hole design on the fire extinguisher tank bracket is convenient for overall lifting. There is no need for complicated disassembly during maintenance. Replacement or maintenance can be completed directly by lifting in or out from the top, which greatly reduces the difficulty and workload of later maintenance and improves the maintainability and ease of operation of the equipment.

[0014] 2. The present invention provides an active fire extinguishing mechanism. The fire extinguisher body is clamped at the bottom by an anti-drop structure, and combined with the tightening effect of the limit clamp, it can effectively prevent accidental falling off during lifting or operation, ensuring the safety of the equipment. During installation, the fire extinguisher assembly is accurately positioned by the limit plate and then fixed to the mounting base A with bolts to form a double stable connection.

[0015] 3. The present invention divides the branch fire extinguishing pipeline into six independently controlled exhaust pipes by setting a diversion pipeline assembly and adopting a modular design of the diversion pipeline assembly. Each exhaust pipe is equipped with an electromagnetic reversing valve. When the sensor detects abnormal temperature or open flame in a certain area, the system only triggers the electromagnetic valve of the corresponding exhaust pipe, so that the fire extinguishing gas is directed to the target fire extinguishing cabinet to achieve precise fire extinguishing. This zoning control method avoids the waste of fire extinguishing resources and greatly shortens the system response time, ensuring that the fire can be quickly suppressed in the early stage, which significantly improves the safety and fire extinguishing efficiency of the locomotive.

[0016] 4. The present invention provides a diversion pipeline assembly with a symmetrical design. Six exhaust pipes are equally distributed on the upper and lower sides of the solenoid valve mounting plate, making full use of the narrow space inside the mounting frame, so that the system can be highly integrated in a limited area. In addition, the modular branch fire extinguishing pipeline design allows the system to flexibly adjust the number and distribution of fire extinguishing cabinets according to actual needs, which not only adapts to the space limitations of existing locomotives, but also provides convenience for subsequent functional expansion, taking into account both space utilization and maintenance convenience.

[0017] 5. The present invention adopts an innovative X-shaped junction box mounting plate design by setting up electrical control components. It is not only strong, but also can make full use of the narrow space on the top of the installation rack and optimize the overall layout. Moreover, the double inspection port design on the junction box mounting plate facilitates the quick disassembly and installation of fasteners, simplifying the maintenance process of components.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1 The conventional locomotive fire protection system in the existing technology is not rationally designed. It mostly adopts an integral structure, and the components are intertwined, which requires the entire system to be disassembled for maintenance. This operation is difficult and time-consuming. In particular, the core components such as the fire extinguisher tank lack a quick positioning and installation structure. When replacing, the position needs to be repeatedly adjusted, which seriously affects the maintenance efficiency. In order to solve this technical defect in the existing technology, Figure 1-Figure 5 As shown, this embodiment proposes a cooling device that is easy to disassemble and maintain the fire extinguishing system. It adopts a modular design, which is convenient for overall lifting and does not require complicated disassembly during maintenance. The cooling device includes a mounting frame 1, an aluminum top cover 2 is fixedly mounted on the upper end of the mounting frame 1, an inspection door assembly 3 is provided on the mounting frame 1, a centrifugal fan 4 for discharging heat is fixedly mounted inside the mounting frame 1, and radiators 6 are symmetrically arranged on both sides of the centrifugal fan 4. An active fire extinguishing mechanism 5 is detachably mounted inside the mounting frame 1, and a fire extinguishing cabinet and a sensor are provided in the locomotive compartment. When the sensor detects an open fire or an excessively high temperature in the compartment, the active fire extinguishing mechanism 5 will automatically input fire extinguishing gas into the fire extinguishing cabinet to extinguish the fire.

[0022] Specifically, the active fire extinguishing mechanism 5 includes a fire extinguishing tank assembly 501, a shunt pipe assembly 502 and an electrical control assembly 503. The interior of the mounting frame 1 is welded with a mounting seat A for mounting the fire extinguishing tank assembly 501. A limit plate is fixedly installed on the mounting seat A. When the fire extinguishing tank assembly 501 falls on the limit plate, the mounting holes can be quickly aligned, thereby reducing the installation time. The fire extinguishing tank assembly 501 includes a fire extinguishing tank body 5011 and a fire extinguishing tank bracket 5013. The fire extinguishing tank bracket 5013 is provided with a limit clamp 5012 for fixing the fire extinguishing tank body 5011. The fire extinguishing tank body 5011 is connected to the main fire extinguishing pipe 5014. The fire extinguishing tank bracket 5013 is provided with an anti-slip structure 5015 that supports the fire extinguishing tank body 5011. Component 502 and electrical control component 503 adopt modular design and can be disassembled and repaired separately, which is convenient for later maintenance. The anti-slip structure 5015 is fixedly installed at the bottom of the fire extinguisher tank bracket 5013 and is used to clamp the fire extinguisher tank body 5011, which can effectively prevent the fire extinguisher tank body 5011 from falling off during the lifting process. A lifting circular hole 5016 is provided on the fire extinguisher tank bracket 5013, and the fire extinguisher tank assembly 501 can be lifted in or out from the inside of the mounting frame 1 through the lifting circular hole 5016, which is convenient for maintenance operations. The radiator 6 is fixedly connected to the mounting frame 1, and the radiator 6 and the centrifugal fan 4 are sealed by a sealing strip. When the centrifugal fan 4 is powered on, the heat generated by the operation of various components in the locomotive can be discharged in time through the radiator 6, thereby achieving a cooling effect.

[0023] According to the above content, when installing the equipment, first open the inspection door assembly 3, clamp the head of the fire extinguisher body 5011 into the anti-slip structure 5015, and then use the limiting clamp 5012 to fix the fire extinguisher body 5011 on the fire extinguisher bracket 5013, and then use the pipe clamp to fix the main fire extinguishing pipeline 5014 on the fire extinguisher bracket 5013, and finally hoist the fire extinguisher assembly 501 from the top of the installation rack 1 through the lifting hole 5016.

[0024] After being hoisted in, the fire extinguisher tank assembly 501 will fall on the limit plate. Next, the staff will use bolts to fix the fire extinguisher tank bracket 5013 and the mounting seat A.

[0025] In this embodiment, an active fire extinguishing mechanism 5 is provided, and the fire extinguisher tank assembly 501, the diversion pipe assembly 502 and the electrical control assembly 503 adopt a modular design. The lifting circular hole 5016 on the fire extinguisher tank bracket 5013 is designed to facilitate overall lifting. There is no need for complicated disassembly during maintenance. Replacement or maintenance can be completed directly by lifting in or lifting out from the top, which greatly reduces the difficulty and workload of later maintenance and improves the maintainability and operational convenience of the equipment. Moreover, in this embodiment, an active fire extinguishing mechanism 5 is provided, and the fire extinguisher tank body 5011 is clamped to the bottom by the anti-slip structure 5015, and combined with the fastening effect of the limit clamp 5012, it can effectively prevent accidental falling off during lifting or operation, ensuring the safety of the equipment. During installation, the fire extinguisher tank assembly 501 is accurately positioned by the limit plate, and then fixed to the mounting seat A with bolts to form a double stable connection.

[0026] Example 2 In order to achieve accurate fire extinguishing and shorten the system response time, based on the first embodiment, Figure 2 and Figure 6 As shown, this embodiment is provided with a diverter pipe assembly 502. Specifically, the diverter pipe assembly 502 includes a mounting base B welded to the inside of the mounting frame 1, and a solenoid valve mounting plate is detachably mounted on the mounting base B. A branch fire extinguishing pipe is fixedly mounted on the solenoid valve mounting plate, and the branch fire extinguishing pipe is connected to the main fire extinguishing pipe 5014. After the fire extinguishing gas inside the fire extinguisher tank body 5011 is discharged through the main fire extinguishing pipe 5014, it will enter each fire extinguishing cabinet through the branch fire extinguishing pipe. The branch fire extinguishing pipe consists of six exhaust pipes, each of which is equipped with an electromagnetic reversing valve to control the on and off of the exhaust pipe. Each exhaust pipe corresponds to a fire extinguishing cabinet in a locomotive, thereby realizing independent operation and precise fire extinguishing. The six exhaust pipes are symmetrically arranged on the upper and lower sides of the solenoid valve mounting plate, which can make full use of the narrow space inside the mounting frame 1.

[0027] According to the above content, important locations of the locomotive (such as the battery cabinet, converter cabinet, driver's cab, etc.) are equipped with fire extinguishing cabinets and sensors. When the temperature of these parts is too high or open flames are generated, the sensors will feed back signals to the main controller. Next, the fire extinguishing tank assembly 501 will discharge high-pressure fire extinguishing gas under the control of the main controller.

[0028] Next, the high-pressure fire extinguishing gas will enter the interior of the branch fire extinguishing pipeline through the main fire extinguishing pipeline 5014. At this time, the electromagnetic reversing valve on the exhaust pipe connected to the fire extinguishing cabinet at the fault location will be automatically connected. Then, the fire extinguishing gas will enter the interior of the fire extinguishing cabinet through the exhaust pipe and spray outward, thereby realizing active fire extinguishing.

[0029] In this embodiment, a branch pipe assembly 502 is provided. Through the modular design of the branch pipe assembly 502, the branch fire extinguishing pipe is divided into six independently controlled exhaust pipes. Each exhaust pipe is equipped with a solenoid reversing valve. When the sensor detects an abnormal temperature or open fire in a certain area, the system only triggers the solenoid valve of the corresponding exhaust pipe, so that the fire extinguishing gas is directed to the target fire extinguishing cabinet to achieve precise fire extinguishing. This zoning control method avoids the waste of fire extinguishing resources and significantly shortens the system response time, ensuring that the fire can be quickly suppressed in the early stage, significantly improving the safety and fire extinguishing efficiency of the locomotive. Moreover, in this embodiment, the branch pipe assembly 502 is provided. The branch pipe assembly 502 adopts a symmetrical design. The six exhaust pipes are equally distributed on the upper and lower sides of the solenoid valve mounting plate, making full use of the narrow space inside the mounting frame 1, so that the system can be highly integrated in a limited area. In addition, the modular branch fire extinguishing pipe design allows the system to flexibly adjust the number and distribution of fire extinguishing cabinets according to actual needs, which not only adapts to the space limitations of existing locomotives but also provides convenience for subsequent functional expansion, taking into account both space utilization and maintenance convenience.

[0030] Example 3 The electrical control assembly 503 includes a mounting base C welded to the inside of the mounting rack 1, and a junction box mounting plate is detachably mounted on the mounting base C. The junction box mounting plate has an "X"-shaped structure, which is not only strong but also can make full use of the narrow space on the top of the mounting rack 1. Two inspection ports are provided on the junction box mounting plate to facilitate the disassembly and assembly of fasteners. A junction box is fixedly mounted on the junction box mounting plate, and a guide rail is fixedly mounted inside the junction box. Components and control cables are provided on the guide rail. The control cables are connected to the fire extinguisher body 5011, the electromagnetic reversing valve, components, and the main controller (not shown in the figure), which can realize the detection of the internal air pressure of the fire extinguisher body 5011 and the control of gas generation.

[0031] This embodiment adopts an innovative "X"-shaped junction box mounting plate design by providing an electrical control component 503. This design not only provides high strength but also fully utilizes the narrow space on top of the mounting rack 1 to optimize the overall layout. Furthermore, the dual inspection ports on the junction box mounting plate facilitate quick disassembly and assembly of fasteners, simplifying the maintenance process of components.

[0032] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0033] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
