Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher installation technology, specifically a fire extinguisher wall-mounted device for a wind turbine tower. Background Technology

[0002] In the safety design of wind turbine generators, fire extinguishers are typically installed inside the tower to address potential fire risks such as electrical short circuits and lubricating oil leaks. Currently, fire extinguishers inside wind turbine towers are mainly wall-mounted, meaning they are fixed to the inner wall of the tower using welded or bolted metal brackets.

[0003] However, existing fire extinguisher brackets have drawbacks:

[0004] First, the installation method is limited and lacks flexibility. Existing brackets are usually fixed to the inner wall of the tower by welding. Each bracket can only hold one fire extinguisher. If the number of fire extinguishers needs to be increased, a new bracket must be welded to the other side of the original bracket, which is cumbersome and affects the structural strength of the tower. In addition, existing brackets are usually designed with a fixed size and can only fit a single size of fire extinguisher cylinder. If a different model of fire extinguisher is replaced, the entire bracket needs to be replaced, which increases maintenance costs. Utility Model Content

[0005] To address the technical problems mentioned above, this utility model provides a fire extinguisher wall-mounted device for a wind turbine tower.

[0006] The technical solution of this utility model is as follows:

[0007] A fire extinguisher wall-mounted device for a wind turbine tower includes a main support frame connected to the inner wall of the wind turbine tower. The lower part of the main support frame has an L-shaped structure. A fire extinguisher placement cylinder is detachably connected to the main support frame. The lower end of the fire extinguisher placement cylinder is inserted into the lower part of the main support frame, and its upper part is connected to the main support frame through a connector.

[0008] The bottom surface of the fire extinguisher placement cylinder is provided with a bottom plate. The fire extinguisher placement cylinder includes a cylinder body. On opposite sides of the cylinder body along its length, there are respectively a matching snap-fit ​​sliding strip and a snap-fit ​​sliding groove. The bottom of the snap-fit ​​sliding strip is provided with a limiting block.

[0009] A support plate is provided on one side of the inner wall of the fire extinguisher placement cylinder. The upper part of the support plate is hinged to the inner wall of the fire extinguisher placement cylinder, and the lower part is elastically connected to the adjacent inner wall of the fire extinguisher placement cylinder through an elastic element.

[0010] The installation position of the lower part of the main support frame and the fire extinguisher placement cylinder is such that the bottom of the fire extinguisher placement cylinder is provided with an installation hole that matches the lower part of the main support frame. The installation hole extends through the fire extinguisher placement cylinder from the side closest to the inner wall of the wind turbine tower to the side away from it.

[0011] The specific structure of the snap-fit ​​slider is that the cross-section of the snap-fit ​​slider along its width direction is a T-shaped surface or a triangular surface. Therefore, the cross-section of the snap-fit ​​groove is adapted to the snap-fit ​​slider.

[0012] The structure of the main support frame is as follows: the main support frame includes an upper plate and a lower plate arranged in parallel, and a vertical plate connecting the upper plate and the lower plate. The upper plate is connected to the inner wall of the wind turbine tower through a fixing plate. The lower plate is located on the opposite side of the upper plate and is inserted into the corresponding mounting hole.

[0013] To enhance the strength of the vertical plate and facilitate the subsequent expansion of additional fire extinguisher placement cylinders on both sides of the existing fire extinguisher placement cylinder, the width of the vertical plate is greater than half the width of the fire extinguisher placement cylinder.

[0014] During operation, the wind turbine tower will vibrate. The main support frame connected to the inner wall of the wind turbine tower and the fire extinguisher placement cylinder connected to the main support frame through connectors may experience a decrease in pre-tightening force due to vibration, affecting the stable connection between the main support frame and the fire extinguisher placement cylinder. Therefore, the vertical plate is connected to the inner wall of the wind turbine tower through a buffer pad.

[0015] To reduce the shaking of the fire extinguisher placement cylinder due to the large gap between it and the bottom plate, the lower end face of the bottom plate is in close contact with the upper end face of the base plate, and the bottom plate can be inserted into the corresponding mounting hole along the upper end face of the base plate.

[0016] Preferably, a single fire extinguisher placement cylinder is detachably connected to a vertical plate via multiple connectors, with the multiple connectors being vertically distributed.

[0017] To make the fire extinguisher placement more visible and to expose part of the extinguisher cylinder, an observation window is provided on one side of the fire extinguisher placement cylinder, located between the mounting hole and the support plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] A fire extinguisher placement cylinder is installed on the main support frame. The rear side of the fire extinguisher placement cylinder is connected to the main support frame. The cylinder body of this fire extinguisher placement cylinder is provided with matching snap-fit ​​sliding strips and snap-fit ​​sliding grooves on the left and right sides respectively. This allows the snap-fit ​​sliding strips of this fire extinguisher placement cylinder to be installed with the snap-fit ​​sliding grooves of another fire extinguisher placement cylinder, and the snap-fit ​​sliding grooves of this fire extinguisher placement cylinder to be installed with the snap-fit ​​sliding strips of another fire extinguisher placement cylinder. By extending in this way, multiple fire extinguisher placement cylinders can be installed, so that the tower of the wind turbine generator set can accommodate a sufficient number of fire extinguishers. There is no need to repeatedly drill holes and damage the tower when adding fire extinguishers. Moreover, the operation of adding fire extinguisher placement cylinders is simple.

[0020] The interior of the fire extinguisher storage cylinder is used to hold fire extinguishers. The internal dimensions of the fire extinguisher storage cylinder are slightly larger than the external dimensions of a commonly used fire extinguisher, so that it can hold fire extinguishers of various sizes. To improve the stability of the fire extinguisher inside the fire extinguisher storage cylinder, a support plate is installed inside the fire extinguisher storage cylinder. The fire extinguisher cylinder is pressed tightly against one side of the support plate, which also has a cushioning effect. Attached Figure Description

[0029] See Figure 1 , Figure 2 and Figure 3 As shown, a fire extinguisher wall-mounted device for a wind turbine tower includes a main support frame 1 connected to the inner wall of the wind turbine tower. The lower part of the main support frame 1 has an L-shaped structure. A fire extinguisher placement cylinder 2 is detachably connected to the main support frame 1. The lower end of the fire extinguisher placement cylinder 2 is inserted into the lower part of the main support frame 1, and its upper part is detachably connected to the main support frame 1 through multiple connectors 3. The multiple connectors 3 are vertically distributed and can be fastening bolts.

[0030] The bottom surface of the fire extinguisher placement cylinder 2 is provided with a bottom plate. The fire extinguisher placement cylinder 2 includes a cylinder body 201. On opposite sides of the cylinder body 201 along its length direction, there are respectively provided with a matching snap-fit ​​sliding strip 202 and a snap-fit ​​sliding groove 203. The bottom of the snap-fit ​​sliding strip 202 is provided with a limiting block 204. The limiting block 204 can restrict the downward movement of the snap-fit ​​sliding groove 203. The fire extinguisher placement cylinder 2 includes a cylinder body 201, a snap-fit ​​sliding strip 202, a snap-fit ​​sliding groove 203 and a limiting block 204.

[0031] The interior of the fire extinguisher placement cylinder 2 is used to place fire extinguishers. The internal dimensions of the fire extinguisher placement cylinder 2 are slightly larger than the external dimensions of a commonly used fire extinguisher, so that it can hold fire extinguishers of various sizes. In order to improve the stability of the fire extinguisher in the fire extinguisher placement cylinder 2, a support plate 6 is installed inside the fire extinguisher placement cylinder 2. The fire extinguisher cylinder is pressed tightly against one side of the support plate 6, which also has a cushioning effect. Specifically, a support plate 6 is provided on one side of the inner wall of the fire extinguisher placement cylinder 2. The upper part of the support plate 6 is hinged to the inner wall of the fire extinguisher placement cylinder 2 via a rotating shaft 7. The rotating shaft 7 is horizontally set, and support blocks are provided at both ends of the rotating shaft 7. The support blocks are connected to the inner wall of the fire extinguisher placement cylinder 2. An elongated hole is opened in the upper part of the support plate 6 along its width direction. The rotating shaft 7 passes through the elongated hole, so that the support plate 6 can rotate inside the fire extinguisher placement cylinder 2. The lower part of the support plate 6 is elastically connected to the adjacent inner wall of the fire extinguisher placement cylinder 2 via an elastic element 8. The elastic element 8 is a compression spring. When the fire extinguisher is placed into the fire extinguisher placement cylinder 2, the fire extinguisher presses down on the lower part of the support plate 6, and the compression spring is compressed, so that the lower part of the support plate 6 can press against the fire extinguisher cylinder.

[0032] See Figure 4 As shown, the installation position of the lower part of the main support frame 1 and the fire extinguisher placement cylinder 2 is such that the bottom of the fire extinguisher placement cylinder 2 is provided with an installation hole 205 that is adapted to the lower part of the main support frame 1. The installation hole 205 penetrates the fire extinguisher placement cylinder 2 from the side close to the inner wall of the wind turbine tower to the side away from it.

[0033] The cross-section of the snap-fit ​​slider 202 along its width direction is a T-shaped surface or a triangular surface. In this embodiment, the cross-section of the snap-fit ​​slider 202 is T-shaped. Similarly, the cross-section of the snap-fit ​​groove 203 is adapted to the snap-fit ​​slider 202.

[0034] A fire extinguisher placement cylinder 2 is installed on the main support frame 1. The rear side of the fire extinguisher placement cylinder 2 is connected to the main support frame 1. The left and right sides of the fire extinguisher placement cylinder 2 are respectively provided with matching snap-fit ​​sliding strips 202 and snap-fit ​​sliding grooves 203, so that the snap-fit ​​sliding strips 202 of the fire extinguisher placement cylinder 2 can be installed with the snap-fit ​​sliding grooves 203 of another fire extinguisher placement cylinder 2, and the snap-fit ​​sliding grooves 203 of the fire extinguisher placement cylinder 2 can be installed with the snap-fit ​​sliding strips 202 of another fire extinguisher placement cylinder 2. Extending in this way, multiple fire extinguisher placement cylinders 2 can be installed, so that the tower of the wind turbine generator set can accommodate a sufficient number of fire extinguishers without the need for multiple drilling and damage operations to the tower when adding fire extinguishers. Moreover, the operation of adding fire extinguisher placement cylinders 2 is simple.

[0035] See Figure 4 and Figure 5 As shown, the main support frame 1 has the following structure: it includes an upper plate 101 and a lower plate 102 arranged parallel to each other, and a vertical plate 103 connecting the upper plate 101 and the lower plate 102. The upper plate 101 is connected to the inner wall of the wind turbine tower through a fixing plate 5. The lower plate 102 is located on the opposite side of the upper plate 101 and is inserted into the corresponding mounting hole 205. The mounting holes 205 are opened on the front and rear sides of the fire extinguisher placement cylinder 2 and are correspondingly opened for insertion and connection with the lower plate 102 of the main support frame 1.

[0036] To reduce the shaking of the fire extinguisher placement cylinder 2 due to the large gap between it and the lower plate 102, the lower end face of the lower plate 102 is in close contact with the upper end face of the base plate, and the lower plate 102 can be inserted into the corresponding mounting hole 205 along the upper end face of the base plate.

[0037] To enhance the strength of the vertical plate 103 and facilitate the subsequent expansion of additional fire extinguisher placement cylinders 2 on both sides of the fire extinguisher placement cylinder 2, the width of the vertical plate 103 is greater than half the width of the fire extinguisher placement cylinder 2.

[0038] See Figure 3 and Figure 5 As shown, during the operation of the wind turbine generator set, the tower will vibrate. The main support frame 1 connected to the inner wall of the wind turbine tower and the fire extinguisher placement cylinder 2 connected to the main support frame 1 through the connector 3 may experience a decrease in pre-tightening force due to vibration, affecting the stable connection between the main support frame 1 and the fire extinguisher placement cylinder 2. Therefore, the vertical plate 103 is connected to the inner wall of the wind turbine tower through the buffer pad 4.

[0039] To make the fire extinguisher placement location conspicuous and expose part of the fire extinguisher cylinder, an observation window 206 is provided on one side of the fire extinguisher placement cylinder 2. The observation window 206 is located between the mounting hole 205 and the support plate 6.
