Description

Technical Field

[0001] This invention relates to the field of fixed structure technology for suspended fire extinguishing devices, specifically to a fire extinguishing device suspension frame and a wind turbine generator set using the same. Background Technology

[0002] To achieve a wider extinguishing range, suspended fire extinguishers need to be installed at a certain height. In conventional factories or some scenarios, where the number of extinguishers is relatively small, they can usually be directly fixed to the ceiling beam with bolts or other structures. However, in some scenarios, especially in applications involving equipment such as wind turbine generators, a large number of suspended fire extinguishers are required. Therefore, moving ladders one by one and fixing them with bolts during use is labor-intensive. Furthermore, conventional wind turbine generator nacelles do not have crossbeams; instead, connecting structures need to be welded to the ceiling and then bolted together. Since the fire extinguishing devices themselves are relatively large, the actual operation and bolting connection are time-consuming and difficult. Summary of the Invention

[0003] To address the problem that bolted connections in fire extinguishing devices are time-consuming and difficult, this invention provides a fire extinguishing device suspension bracket and a wind turbine generator set using the same.

[0004] The technical solution of this invention is as follows:

[0005] A fire extinguishing device suspension bracket includes a hanging beam, a clamping frame, and a mounting plate;

[0006] The hanging beam is horizontally fixed on the reference plane and has multiple symmetrical fixed grooves along its length. The fixed grooves are used to suspend and limit the clamping frame.

[0007] The clamping frame includes a control rod, and clamping arms are symmetrically arranged at both ends of the control rod. The clamping arms are rotatably connected to the control rod. The upper end of the clamping arm can be suspended in the fixed sink, and the lower end of the clamping arm is rotatably connected to a connecting rod.

[0008] The upper surface of the mounting plate is rotatably connected to the end of the connecting rod away from the clamping arm, and the lower surface can be connected to the fire extinguishing device.

[0009] By using a clamping frame structure, after fixing the fire extinguishing device to the mounting plate, it is only necessary to connect the symmetrical hanging beams of the clamping frame, eliminating the need for fixing bolts. Therefore, it is more efficient and the process is simpler.

[0010] To improve stability, the distance between the openings at the top of the two clamping arms decreases as the control lever is raised. This ensures greater stability when the fire extinguishing device and mounting plate fall due to gravity.

[0011] Preferably, both ends of the clamping arm are bent towards the side closer to the center of the control lever. Therefore, when the lower end of the clamping arm rotates outward, the upper end of the clamping arm moves inward.

[0012] Based on the above structure, furthermore, in the horizontal direction, the distance between the upper ends of the two connecting rods is smaller than the distance between their lower ends. When the mounting plate moves downward, it can pull the lower end of the clamping arm to rotate outward.

[0013] For ease of manual operation, a handle is provided in the middle of the control lever. It is easy to hold and does not easily slip.

[0014] To make the structural connection between the hanging beam and the clamping frame more stable, a hook is provided at the upper end of the clamping arm, which can be connected with the fixed sink.

[0015] The specific structure of the clamping arm is as follows: the clamping arm includes a bent lower arm that is lower than the control rod and a bent upper arm that is higher than the control rod.

[0016] Preferably, the length of the bent upper arm is greater than the length of the bent lower arm.

[0017] Specifically, when the hanging beam, clamping frame, and mounting plate are relatively stationary, the lower surface of the mounting plate is horizontal. This ensures that the fire extinguishing device installed behind the mounting plate will not tilt and affect its use.

[0018] A wind turbine generator set includes a fire extinguishing device suspension frame as described above. The suspension beam is positioned above the main shaft of the wind turbine generator set, and its length direction is the same as that of the main shaft. Multiple clamping frames and mounting plates are correspondingly installed on the suspension beam, and a fire extinguishing device is fixed beneath each mounting plate. Since easily flammable components within the wind turbine generator set, such as the gearbox, generator, brake discs, and cables, are primarily located around the main shaft, the suspension beam must also be designed according to this standard.

[0019] The beneficial effects of this invention are as follows: This invention is a fire extinguishing device suspension bracket and a wind turbine generator set using it. Unlike the existing bolt fixing method, this device installs the fire extinguishing device through a clamping bracket. The clamping bracket can be adjusted and hung in any fixed groove of the hanging beam. Under the gravity pull of the mounting plate for installing the fire extinguishing device, the clamping bracket can clamp the hanging beam to make the fixing structure more stable. When disassembling, it is only necessary to move the control rod and the mounting plate relative to each other. The entire process does not require the use of any tools, so workers can perform disassembly and assembly operations with their bare hands. Attached Figure Description

[0023] Figure 2 This is a schematic diagram of the disassembled structure of the present invention;

[0024] Figure 3 This is a schematic diagram of the top view of the hanging beam structure of the present invention;

[0025] The components represented by the various reference numerals in the diagram are:

[0026] 1. Mounting plate; 2. Clamping bracket; 21. Connecting rod; 22. Clamping arm; 221. Bent lower arm; 222. Bent upper arm; 223. Hook; 23. Control lever; 231. Handle; 3. Hanging beam; 31. I-beam; 32. Fixed sink; 4. Fire extinguishing device. Detailed Implementation

[0027] like Figure 1 , 2 The fire extinguishing device suspension bracket shown includes:

[0028] The hanging beam 3 is horizontally fixed on the reference plane and has multiple symmetrical fixing grooves 32 along its length. The purpose of the fixing grooves 32 is to be used to install multiple fire extinguishing devices or to move a fire extinguishing device to different positions. The hanging beam 3 can be fixed to the reference plane in various ways. When a detachable structure is required, it can be connected by bolts or similar structures. When a detachable connection is not required and only a stable fixing effect is needed, the hanging beam 3 can be directly welded to the required position.

[0029] The hanging beam 3 includes an I-beam 31 with an I-shaped cross-section. A sunken fixed groove 32 is provided above the I-beam 31 near its middle position. Figure 3 As shown, the fixed sinkhole 32 can be a fixed countersunk hole, that is, it penetrates the structure of the I-beam 31. This setting can be selected arbitrarily according to the requirements.

[0030] Subsequently, based on the above structure, a clamping frame 2 is further provided. The clamping frame 2 includes a control rod 23, and clamping arms 22 are symmetrically arranged at both ends of the control rod 23. The clamping arms 22 are rotatably connected to the control rod 23, so that the entire clamping arm 22 can rotate. The specific structure of the clamping arm 22 is as follows: the clamping arm 2 includes a bent lower arm 221 lower than the control rod 23 and a bent upper arm 222 higher than the control rod 23. The connection position of the bent lower arm 221 and the bent upper arm 222 is the rotation connection point with the control rod 23, and the length of the bent upper arm 222 is greater than the length of the bent lower arm 221, because the bent upper arm 222 needs to be used to clamp the hanging beam 3.

[0031] The end of the clamping arm 22 that is higher than the control rod 23, that is, the end of the bent upper arm 222 that is away from the bent lower arm 221, can be fixed to the hanging beam 3 to achieve the fixation of the entire clamping frame 2 and the hanging beam 3. At the same time, the bent upper arm 222 is limited by the fixed groove 32 in the length direction of the hanging beam 3 and cannot move. Therefore, when using it, the bent upper arm 222 needs to be aligned with the appropriate fixed groove 32.

[0032] To ensure a more stable structural connection between the hanging beam 3 and the clamping frame 2, a hook 223 is provided at the end of the clamping arm 22 that is higher than the control rod 23, i.e., the end of the bent upper arm 222 that is away from the bent lower arm 221. The hook 223 can cooperate with the fixed sink 32 to achieve the desired effect. Figure 1 The effect of the connection shown.

[0033] The clamping arm 22 is lower than the control rod 23 at one end, that is, the end of the bent lower arm 221 away from the bent upper arm 222 is rotatably connected to the connecting rod 21. The connecting rod 21 is used to connect the mounting plate 1. If the mounting plate 1 is directly fixed to the bent lower arm 221 and cooperates with the control rod 23, the entire clamping arm 22 cannot rotate, and the device cannot be used normally. Therefore, the design of the connecting rod 21 is necessary.

[0034] Finally, there is the mounting plate 1. The upper surface of the mounting plate 1 is rotatably connected to the end of the connecting rod 21 away from the clamping arm 22, and the lower surface can be connected to the fire extinguishing device 4. As a structure that is directly connected to the fire extinguishing device 4, the mounting plate 1 needs to be provided with bolt holes or other connection structures for the fire extinguishing device 4, and the structure is not limited. Since there is no requirement for the usage time of the mounting plate 1 and the fire extinguishing device 4 during the use of this device, the fire extinguishing device 4 can be fixed to the mounting plate 1 before the clamping frame 2 is connected to the hanging beam 3. The fixing method is not required, as long as the fire extinguishing device 4 cannot be detached from the mounting plate 1.

[0035] Meanwhile, when the clamping frame 2 is fixed to the hanging beam 3, that is, when the hanging beam 3, clamping frame 2, and mounting plate 1 are relatively stationary, the lower surface of the mounting plate 1 is horizontal. This ensures that the fire extinguishing device 4 installed behind the mounting plate 1 will not tilt and affect its use.

[0036] In the above structure, by using the clamping frame 2 structure, after the fire extinguishing device 4 is fixed to the mounting plate 1, it is only necessary to connect the symmetrical hanging beams 3 of the clamping frame 2, eliminating the need for fixing bolts. Therefore, the efficiency is high and the process is relatively simple.

[0037] Preferably, to improve the fixing strength between the clamping frame 2 and the hanging beam 3, the clamping frame 2 is configured such that the greater the distance between the control rod 23 and the mounting plate 1, the smaller the distance between the ends of the two clamping arms 22 that are higher than the control rod 23. This ensures that the clamping frame 2 and the hanging beam 3 are more stably fixed when the fire extinguishing device 4 and the mounting plate 1 are subjected to gravity and fall downwards.

[0038] To achieve the above effect, the necessary structural design is as follows: both ends of the clamping arm 22 are bent towards the center of the control rod 23, that is, the bent upper arm 222 and the bent upper arm 221 are inclined. Therefore, when the lower end of the clamping arm 22 rotates outward, the upper end of the clamping arm 22 will move inward. For this reason, it is only necessary to ensure that the falling of the mounting plate 1 pulls the lower end of the bent upper arm 221 to rotate outward to achieve the above technical effect. Therefore, the required design is as follows:

[0039] In the horizontal direction, the distance between the upper ends of the two connecting rods 21 is smaller than the distance between their lower ends. For example... Figures 2 to 1 As shown in the diagram, when the position of the control lever 23 is constant and the mounting plate 1 falls, the mounting plate 1 will pull the connecting rod 21 to rotate. Simultaneously, the connecting rod 21 will pull the lower end of the bent upper arm 221 to rotate outwards. Correspondingly, the upper end of the bent upper arm 222 will rotate inwards, thus achieving the desired state. Figure 1 In the state shown, a lateral clamping force is guaranteed, which can make the clamping arm 22 more secure.

[0040] As can be seen from the above structure, the adjustment of the clamping frame 2 is mainly achieved by the relative movement of the control lever 23 and the mounting plate 1. To facilitate manual adjustment, a handle 231 is provided in the middle of the control lever 23. This handle 231 is convenient to hold and prevents slippage. Figure 2 Status switch to Figure 1At this time, simply use both hands to control the handle 231 and the mounting plate 1 respectively, ensuring the distance between the upper ends of the clamping arms 22 is greater than that of the hanging beam 3. When it is located in the vertical section of the I-beam 31, pull down the mounting plate 1 so that the upper ends of the clamping arms 22 are tightly against the I-beam 31. Then, simultaneously align the handle 231 and the mounting plate 1 with the appropriate mounting groove 32 and lower them. This will achieve the desired effect. Figure 1 In the state shown, conversely, move the handle 231 and the mounting plate 1 upwards simultaneously, keeping the handle 231 stationary, and raise the mounting plate 1 so that the distance between the upper ends of the clamping arms 22 is greater than the width of the I-beam 31, then it can be disassembled.

[0041] A wind turbine generator set includes a fire extinguishing device suspension frame as described above. The suspension beam 3 is positioned above the main shaft of the wind turbine generator set, with its length aligned with the length of the main shaft. Multiple clamping frames 2 and mounting plates 1 are correspondingly mounted on the suspension beam 3, and a fire extinguishing device 4 is fixed beneath each mounting plate 1. Since easily flammable components within the wind turbine generator set, such as the gearbox, generator, brake discs, and cables, are primarily arranged around the main shaft, the suspension beam 3 must also adhere to this standard. Following the aforementioned installation steps, the mounting plate 1 with the fire extinguishing device 4 installed is then positioned on the corresponding location on the suspension beam 3 using the clamping frames 2.
