Description

Technical Field

[0001] This utility model relates to the field of generator set fire protection technology, specifically to a fire protection device used in generator sets. Background Technology

[0002] In the energy supply system of modern society, generator sets play a vital role and are widely used in industrial production and commercial operations.

[0003] However, during long-term operation, generator sets pose a potential fire risk due to various factors such as aging electrical wiring, short circuits, overloads, frictional heat from mechanical parts, and lubricating oil leaks encountering high-temperature components. Once a fire breaks out in a generator set, the flames often spread rapidly, causing severe damage to the generator set itself, rendering it unable to function properly and disrupting normal production and daily life. Furthermore, it can easily trigger a chain reaction, threatening the safety of surrounding equipment and personnel.

[0004] Currently, existing firefighting methods for generator sets are significantly inadequate. When a generator set catches fire, it is difficult to achieve comprehensive fire suppression. Furthermore, the complex structure of generator sets allows fire sources to easily hide in various corners. In most cases, firefighting still relies primarily on manual methods. However, manual firefighting has many limitations. Due to a lack of professional firefighting equipment and protective measures, it faces significant safety risks during the firefighting process. In addition, manual firefighting cannot quickly and comprehensively cover the fire scene, failing to effectively control the spread of the fire in a timely manner, often leading to further fire damage.

[0005] Therefore, based on this, a design or technical improvement is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned shortcomings and provide a fire-fighting device for generator sets.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A fire-fighting device for a generator set includes a bracket, on which multiple sets of support plates are fixedly installed, and on which the generator set body is disposed. A mounting box is fixedly installed at one end of the bracket, and a fixing frame is fixedly installed on both sides of the bracket.

[0009] The installation box contains multiple storage tanks, each containing liquid carbon dioxide. Each storage tank is connected to a drain pipe, which in turn is connected to a guide pipe. The guide pipe extends through both sides of the installation box, and both ends of the guide pipe are connected to delivery pipes. A rotary joint is rotatably connected to the end of the delivery pipe. One end of the rotary joint is connected to a connecting pipe, and the other end of the connecting pipe is connected to a manifold. A shaft is fixedly installed at one end of the manifold, and the shaft is rotatably connected to the inner wall of the fixed frame. The manifold is equipped with multiple nozzles.

[0010] Each of the fixed frames is fixedly equipped with an electric push rod at its bottom end, and a connecting rod is fixedly installed at the end of the electric push rod, the connecting rod being fixedly connected to the manifold.

[0011] The bracket is equipped with an auxiliary positioning component for convenient installation of the generator set body.

[0012] Furthermore, the auxiliary positioning component includes a long rod fixedly connected to the electric push rod, and both ends of the long rod are fixedly mounted with mounting shells. The inner wall of the mounting shell is provided with multiple sets of springs, and the ends of the multiple sets of springs are fixedly connected with telescopic blocks. The ends of the telescopic blocks are fixedly connected with limit blocks, and the limit blocks are located at the top of the support plate.

[0013] Furthermore, the drain pipe is equipped with an electronic valve and a pressure booster, and the inner wall of the bracket is equipped with a switch for controlling the electronic valve and the pressure booster.

[0014] Furthermore, multiple sets of fixing rings are fixedly installed on the guide pipe, and each set of fixing rings is fixedly installed with a support rod, and the support rods are all fixedly connected to the bracket.

[0015] Furthermore, a protective shell is provided on the fixed frame, and an electric push rod is provided inside the protective shell.

[0016] Furthermore, limit plates are fixedly installed on all of the aforementioned support plates.

[0017] Compared with existing technologies, the beneficial effects of this solution are:

[0018] 1. This system allows for rapid control of the electronic valve and pressurizer via a switch. The electronic valve opens quickly, allowing liquid carbon dioxide to flow out of the storage tank in a timely manner. The pressurizer simultaneously pressurizes, ensuring that the liquid carbon dioxide enters the subsequent pipeline with sufficient pressure and flow. Multiple storage tanks work in concert, with liquid carbon dioxide smoothly entering the manifold through the drain pipe, guide pipe, delivery pipe, and rotary joint, and then rapidly distributed to multiple nozzles. The nozzles spray the liquid carbon dioxide in a mist or fine particulate form, completely covering the surface of the generator set. By cooling and isolating oxygen, it rapidly suppresses the spread of fire, achieving highly efficient fire suppression and greatly reducing the damage to the generator set from the fire.

[0019] 2. This solution uses an electric actuator to drive the manifold to swing around a shaft. A rotary joint ensures a smooth connection between the delivery pipe and the manifold, without affecting the delivery of liquid carbon dioxide. This swinging motion allows multiple nozzles to be adjusted vertically, resulting in a more uniform and wider-coverage spray of the extinguishing medium, effectively improving fire suppression efficiency, ensuring timely fire extinguishing, and guaranteeing the safe operation of the generator set.

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figure 1-7 The fire-fighting device for a generator set shown includes a bracket 1. Multiple support plates 211 are fixedly mounted on the bracket 1, and the generator set body 3 is mounted on the support plates 211. A mounting box 2 is fixedly mounted at one end of the bracket 1, and mounting frames 4 are fixedly mounted on both sides of the bracket 1. Multiple storage tanks 111 are installed inside the mounting box 2, each storing liquid carbon dioxide. Each storage tank 111 is connected to a drain pipe 113, which is connected to a guide pipe 811. The guide pipe 811 passes through both sides of the mounting box 2, and its two ends are connected to... There is a transmission pipe 911, and a rotary joint 512 is rotatably connected to the end of the transmission pipe 911. One end of the rotary joint 512 is connected to the connecting pipe 511, and one end of the connecting pipe 511 is connected to the manifold 6. A shaft 5 is fixedly installed at one end of the manifold 6. The shaft 5 is rotatably connected to the inner wall of the fixed frame 4. The manifold 6 is provided with multiple sets of nozzles 7. An electric push rod 711 is fixedly installed at the bottom of the fixed frame 4. A connecting rod 9 is fixedly installed at the end of the electric push rod 711. The connecting rod 9 is fixedly connected to the manifold 6. An auxiliary positioning component is provided on the bracket 1 for convenient installation of the generator set body 3.

[0031] In one embodiment, the auxiliary positioning component includes a long rod 411 fixedly connected to an electric push rod 711, with mounting shells 314 fixedly installed at both ends of the long rod 411. Multiple sets of springs 313 are provided on the inner wall of the mounting shells 314, and telescopic blocks 312 are fixedly connected to the ends of the springs 313. Limiting blocks 311 are fixedly connected to the ends of the telescopic blocks 312, and the limiting blocks 311 are located at the top of the support plate 211. The limiting blocks 311 on both sides work together to position the generator set body 3 from two directions, making the installation process more efficient. Operators do not need to repeatedly adjust the position of the generator set body 3; they only need to control the movement of the limiting blocks 311 through the electric push rod 711 to quickly complete the initial positioning of the generator set body 3, greatly shortening the installation time and improving work efficiency. When the limiting block 311 abuts against the outer surface of the generator set body 3, the elasticity of the springs 313 allows the telescopic blocks 312 to extend and retract within the mounting shells 314, thereby achieving adaptive adjustment of the limiting blocks 311 to the generator set body 3.

[0032] In one embodiment, an electronic valve 114 and a pressure booster 116 are provided on the drain pipe 113. The electronic valve 114 can precisely control the flow of liquid carbon dioxide in the drain pipe 113, and the pressure booster 116 can pressurize the liquid carbon dioxide in the drain pipe 113 to ensure that the liquid carbon dioxide can enter the subsequent pipeline with sufficient pressure and flow. A switch 112 is provided on the inner wall of the bracket 1, and the operator can operate the electronic valve 114 and the pressure booster 116 in a unified manner through the switch 112.

[0033] In one embodiment, multiple sets of fixing rings 115 are fixedly installed on the guide pipe 811, and each set of fixing rings 115 is fixedly installed with a support rod 117. The support rods 117 are fixedly connected to the bracket 1. The fixing rings 115 and the support rods 117 can play a good role in fixing and supporting the guide pipe 811.

[0034] In one embodiment, a protective shell 8 is provided on the fixed frame 4, and an electric push rod 711 is provided inside the protective shell 8. The protective shell 8 encloses the electric push rod 711, which can effectively protect the electric push rod 711 from interference and damage from the external environment.

[0035] In one embodiment, limit plates 212 are fixedly installed on multiple sets of support plates 211. The limit plates 212 can prevent the limit blocks 311 from moving excessively, ensuring that the limit blocks 311 always position the generator body 3 within a reasonable range, thereby improving the accuracy and stability of the installation process.

[0036] The specific workflow of this plan is as follows:

[0037] When a fire occurs in the main body 3 of the generator set, people press switch 112, at which time electronic valve 114 opens, allowing liquid carbon dioxide in storage tank 111 to flow out smoothly. At the same time, pressurizer 116 also opens to pressurize the liquid carbon dioxide to ensure that it can enter the subsequent pipeline with sufficient pressure and flow.

[0038] Liquid carbon dioxide in multiple storage tanks 111, under pressure, flows through drain pipe 113 into guide pipe 811. Guide pipe 811 is securely fixed to support 1 by fixing ring 115 and support rod 117, ensuring the stability of the conveying process. Liquid carbon dioxide continues to flow within guide pipe 811 and enters delivery pipe 911 at both ends of guide pipe 811. Delivery pipe 911 is connected to manifold 6 via rotary joint 512, allowing liquid carbon dioxide to smoothly enter manifold 6 through rotary joint 512.

[0039] After liquid carbon dioxide enters the manifold 6, it is quickly distributed to multiple sets of nozzles 7. The nozzles 7 spray the liquid carbon dioxide in the form of mist or fine particles, covering the surface of the generator set body 3. By reducing the temperature and isolating oxygen, the spread of fire is quickly suppressed, thus achieving the purpose of extinguishing the fire.

[0040] To ensure the extinguishing medium is evenly sprayed onto all parts of the generator set body 3 and improve the extinguishing effect, an electric push rod 711 is driven. The piston rod of the electric push rod 711 extends, pushing the connecting rod 9 forward. The connecting rod 9 is fixedly connected to the manifold 6, thus causing the manifold 6 to move together. Since the shaft 5 at one end of the manifold 6 is rotatably connected to the inner wall of the fixed frame 4, the manifold 6 will swing around the shaft 5 under the push of the electric push rod 711. The rotary joint 512 ensures that the connection between the delivery pipe 911 and the manifold 6 remains unobstructed during the swinging process of the manifold 6, without affecting the normal delivery of liquid carbon dioxide. Through this swinging motion, the multiple nozzles 7 can adjust their vertical angle, thereby making the sprayed extinguishing medium more even, covering a wider area, and effectively improving the extinguishing efficiency.

[0041] During the installation of the generator set body 3, the auxiliary positioning component can provide a convenient installation method. Before installing the generator set body 3, the electric push rod 711 is in a retracted state, and the long rod 411 and the limiting block 311 are located on the side close to the electric push rod 711. The generator set body 3 is initially placed on the multiple support plates 211 on the bracket 1 by bolts, but at this time the generator set body 3 is not completely fixed in place.

[0042] At this point, the electric push rod 711 is driven, and its piston rod extends, pushing the long rod 411 forward. Under the limiting action of the limiting plate 212, the limiting block 311 moves smoothly along the surface of the support plate 211, gradually approaching the generator set body 3. When the limiting block 311 abuts against the outer surface of the generator set body 3, the multiple sets of springs 313 set on the inner wall of the mounting shell 314 will function. The springs 313 have a certain elasticity, allowing the telescopic block 312 to extend and retract to a certain extent within the mounting shell 314. In this way, the limiting block 311 can adaptively adjust according to the actual size of the generator set body 3, ensuring a tight fit against the outer surface of the generator set body 3, thereby achieving precise positioning and auxiliary fixation of the generator set body 3. Afterward, by further tightening the bolts, the generator set body 3 is firmly fixed to the support plate 211.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
