Description

Technical Field

[0001] This invention relates to the field of substation equipment technology, and more specifically, to a substation fire protection system. Background Technology

[0002] For substations built in mountainous or hilly areas, some substations have at least one side facing a mountain, or even are surrounded by mountains on all four sides, making them prone to wildfires in dry environments. Existing fire prevention measures for some substations only focus on the impact on internal equipment, neglecting external risks, leading to insufficient response time in the event of a wildfire.

[0003] In response to the above situations, some substations, when faced with external fires and unavailable firefighters, can only temporarily assemble fire hoses and spray water onto the perimeter wall to soak weeds and prevent the fire from spreading into the wall. However, this method has an insufficient spray range, and dragging the hoses is time-consuming and labor-intensive, making it impossible to quickly evacuate areas with strong fires. Furthermore, the workers are also in danger. Some substations were designed with the idea of ​​digging protective trenches outside the substation and storing water in them to create a moat-like firebreak. However, during the rainy season, mudslides can easily block these trenches or cause backflow, and the construction of such trenches is a significant undertaking.

[0004] Therefore, there are no good existing technologies to deal with the impact of wildfires outside the substation on the substation. Summary of the Invention

[0005] The main objective of this invention is to provide a substation fire protection system to address the problem in related technologies of the lack of effective measures to deal with the impact of wildfires outside the substation.

[0006] To achieve the above objectives, the present invention provides a substation fire protection system, comprising: a perimeter wall, which is disposed around the substation and includes a wall corresponding to a mountain; and a sprinkler system disposed on the wall, which includes a rotatable water gun structure capable of spraying fire extinguishing liquid toward the outside of the wall.

[0007] Furthermore, fire windows are installed on the wall, and the substation fire protection system also includes a window door installed on the outside of the fire windows. The water gun structure includes a first water gun located inside the wall and corresponding to the fire windows. The window door has a blocking position for blocking the fire windows and an open position for exposing the fire windows. The window door is hinged to the wall and can be flipped outward to switch from the blocking position to the open position.

[0008] Furthermore, the sprinkler system also includes a delivery pipeline installed inside the wall and capable of delivering extinguishing liquid to the first water gun. The delivery pipeline includes a fixed section and a rotating section that are interconnected. The fixed section is fixedly connected to the wall. The first end of the rotating section is rotatably connected to the fixed section in the lateral direction and has a storage position located inside the window or door and an extinguishing position extending into the fire window or out of the wall. The first water gun is installed at the second end of the rotating section and is connected to the rotating section.

[0009] Furthermore, the spraying device also includes a first shielding frame connected to the rotating section and covering the outer periphery of the first water gun.

[0010] Furthermore, the first shielding frame includes a top plate, a bottom plate, and a support rod connecting the top plate and the bottom plate. A connection port is provided on the bottom plate, and the second end of the rotating section passes through the connection port.

[0011] Furthermore, the first shielding frame also includes a support leg disposed below the base plate, with the bottom wall of the fire window supported below the support leg; and / or, the first shielding frame also includes a reinforcing folding rod connected between the base plate and the second end of the rotating section.

[0012] Furthermore, the sprinkler system also includes a limiting rod installed inside the fire window, a first limiting plate installed on the limiting rod, and a second limiting plate installed on the first shield. The first limiting plate is provided with a first limiting groove. When the rotating section is in the fire extinguishing position, the first shield is fixedly connected to the limiting rod and the first limiting plate by fasteners passing through the first limiting groove and the second limiting plate, so that the rotating section is kept in the fire extinguishing position.

[0013] Furthermore, the spraying device also includes a gate valve and a drip valve installed on the fixed section. The gate valve has a conducting state that allows the conveying pipeline to be opened and a blocking state that blocks the conveying pipeline. The drip valve is installed between the gate valve and the rotating section.

[0014] Furthermore, the water gun structure includes a second water gun installed at the top of the wall, the second water gun being connected to the inside of the wall via a mounting bracket, and the spraying device also includes a second shielding bracket covering the outer periphery of the second water gun.

[0015] Furthermore, the substation fire protection system also includes a detection device electrically connected to the sprinkler system, which can detect wildfire conditions and send detection information to the sprinkler system.

[0016] By applying the technical solution of this invention, a sprinkler system is installed on the outer wall of the substation. The sprinkler system includes a water gun structure. When a fire occurs outside the substation, workers can use the water gun structure to spray water onto the outside of the wall to prevent the wildfire from spreading and intruding into the substation. The water gun structure is rotatably mounted on the wall, allowing it to cover a large area outside the wall, ensuring effective fire extinguishing or fire suppression. Furthermore, the water gun structure is directly installed on the wall, resulting in a lower workload. Therefore, the technical solution of this application effectively solves the problem in related technologies of lacking effective measures to address the impact of wildfires outside the substation.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] As 1 to Figure 7As shown, this application provides a substation fire protection system, wherein an embodiment of the substation fire protection system of this application includes a perimeter wall 10 and a sprinkler system 20. The perimeter wall 10 is located on the outer perimeter of the substation and includes a wall 11 corresponding to a mountainside. The sprinkler system 20 is mounted on the wall 11 and includes a rotatably mounted water gun structure 21 capable of spraying fire extinguishing liquid onto the outer side of the wall 11.

[0034] Applying the technical solution of this embodiment, a sprinkler system 20 is installed on the outer wall 11 of the substation. The sprinkler system 20 includes a water gun structure 21. When a fire occurs outside the substation, workers can spray water onto the outside of the wall 10 through the water gun structure 21 to prevent the wildfire from spreading and intruding into the substation. The water gun structure 21 is rotatably mounted on the wall 11, allowing it to cover a large area outside the wall 10, ensuring the effectiveness of extinguishing or blocking the fire. Furthermore, directly installing the water gun structure 21 on the wall 11 requires minimal engineering work. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where there are no good measures to address the impact of wildfires outside the substation on the substation.

[0035] It should be noted that the wall 10 in this embodiment is a structure that the substation itself already has. In this embodiment, a sprinkler device 20 is added to the wall 10, which has the advantage of being easy to construct.

[0036] like Figure 1 as well as Figures 4 to 6 As shown, a fire window 111 is provided on the wall 11. The substation fire protection system also includes a door 30 located outside the fire window 111. The water gun structure 21 includes a first water gun 211 located inside the wall 11 and corresponding to the fire window 111. The door 30 has a blocked position for blocking the fire window 111 and an open position for exposing the fire window 111. The door 30 is hinged to the wall 11 and can be flipped outward to switch from the blocked position to the open position. By opening a fire window 111 on the wall 11 and setting a flip-out door 30 on the outside of the wall 11 corresponding to the fire window 111, when the first water gun 211 needs to be activated, the door 30 can be opened to expose the first water gun 211; after use, the door 30 can be closed.

[0037] Specifically, the window 30 is made of stainless steel. The opening angle of the window 30 is adjustable. When the window 30 is closed, it can be fixed with a latch. This makes it easy to maintain and also provides high security.

[0038] like Figure 1 as well as Figures 4 to 6As shown, the sprinkler system 20 also includes a delivery pipe 22 disposed inside the wall 11 and capable of delivering fire extinguishing liquid to the first water gun 211. The delivery pipe 22 includes a fixed section 221 and a rotating section 222 that are interconnected. The fixed section 221 is fixedly connected to the wall 11. The first end of the rotating section 222 is rotatably connected to the fixed section 221 in the lateral direction and has a storage position located inside the window 30 and a fire extinguishing position extending into the fire window 111 or extending out of the wall 11. The first water gun 211 is disposed at the second end of the rotating section 222 and is connected to the rotating section 222. Specifically, in this embodiment, the fixed section 221 extends vertically and the rotating section 222 extends horizontally. The rotating section 222 can rotate around the axis of the fixed section 221, so that when the first water gun 211 needs to be activated, the first water gun 211 can extend outward as much as possible to cover a larger spraying range; after use, the first water gun 211 can be stored inside the window 30.

[0039] like Figure 1 and Figure 2 As shown, the spray device 20 also includes a first shield 23 connected to the rotating section 222 and covering the outer periphery of the first water gun 211. The first shield 23 covers the outer periphery of the first water gun 211 and can protect the first water gun 211, especially the connection position between the first water gun 211 and the rotating section 222, reduce the wear and tear caused by sun and rain on the first water gun 211, and ensure the service life of the first water gun 211.

[0040] like Figure 4 and Figure 5 As shown, the first water gun 211 has three states: the first state is the normal state (i.e., Figure 4 The first state is when the window 30 is open but the rotating section 222 remains in the retracted position (not shown in the figure). The second state is when the window 30 is open but the rotating section 222 remains in the retracted position (i.e., the first state is when the window 30 is open but the rotating section 222 remains in the retracted position). The third state is when the window 30 is open and the rotating section 222 is rotated to the fire extinguishing position (i.e., the second state is when the window 30 is open but the rotating section 222 remains in the retracted position). Figure 5 (The states are described in the original text). The window / door 30 includes a window frame fixedly connected to the fire window 111 and a door body that is rotatably connected to the window frame. In the first state, the first water gun 211 is located inside the window frame and close to it, forming a small angle with the plane of the window frame. This arrangement allows the door body to close, ensuring the integrity of the wall and not compromising its function. When the first water gun 211 needs to operate, the door body flips outward, and a limiting structure ensures that the door body flips outward to a position with an angle of 10° to 15° with the horizontal plane, reaching the second state. In the third state, the rotating section 222 drives the first water gun 211 to rotate, extending it outside the wall 11.

[0041] like Figure 1 and Figure 2As shown, the first shielding frame 23 includes a top plate 231, a bottom plate 232, and a support rod 233 connecting the top plate 231 and the bottom plate 232. The bottom plate 232 is provided with a connection port 234, and the second end of the rotating section 222 passes through the connection port 234. The second end of the rotating section 222 passes through the connection port 234 and is connected to the first water gun 211, which can effectively protect the first water gun 211.

[0042] like Figure 1 and Figure 2 As shown, the first shielding frame 23 also includes a support leg 235 disposed below the base plate 232, and the bottom wall of the fire window 111 is supported below the support leg 235. The support leg 235 is provided to support the first shielding frame 23 and the first water gun 211.

[0043] like Figure 1 and Figure 2 As shown, the first shield 23 has two support legs 235, and the sprinkler device 20 also includes a limiting block 244 set on the bottom wall of the fire window 111. When the rotating section 222 is in the storage position, one of the support legs 235 cooperates with the limiting block 244 to stop and limit the first shield 23 and the first water gun 211 in that position.

[0044] like Figure 1 and Figure 2 As shown, the first shielding frame 23 also includes a reinforcing folding rod 236 connecting the base plate 232 and the second end of the rotating section 222. Since the first water gun 211 has a certain inward recoil force when spraying fire extinguishing liquid outward, the reinforcing folding rod 236 can be used to reinforce the area between the rotating section 222 and the base plate.

[0045] like Figure 1 and Figure 2 As shown, the sprinkler system 20 also includes a limiting rod 241 installed inside the fire window 111, a first limiting piece 242 installed on the limiting rod 241, and a second limiting piece installed on the first shield 23. The first limiting piece 242 has a first limiting groove 243. When the rotating section 222 is in the fire extinguishing position, the first shield 23 is fixedly connected to the limiting rod 241 and the first limiting piece 242 by fasteners passing through the first limiting groove 243 and the second limiting piece, so that the rotating section 222 is kept in the fire extinguishing position. When the rotating section 222 rotates to the fire extinguishing position, the operator can install fasteners to fix the first shield 23 and the first limiting piece 242, so that the rotating section 222 can be kept in that position, thus ensuring the stability of the first water gun 211 during operation. This design has the advantages of simple structure and simple operation.

[0046] Specifically, in order to install the first water gun 211 on the wall 11, in addition to making a hole in the wall 11, a fire gun platform needs to be built at the hole location. The fire gun platform and the hole together form the fire window 111, that is, the upper surface of the fire gun platform forms the bottom wall of the fire window 111.

[0047] Specifically, in this embodiment, the fastener includes a screw passing through the first limiting groove 243 and the second limiting piece, and a nut disposed on the screw.

[0048] like Figure 6 As shown (where 211(a) and 222(a) indicate the states of the first water gun 211 and the rotating section 222 when the rotating section 222 is in the retracted position or begins to rotate outward from the retracted position; 211(b) and 222(b) indicate the states of the first water gun 211 and the rotating section 222 when the rotating section 222 is in the fire extinguishing position), in order to ensure that the first water gun 211 can extend as far as possible out of the wall 11 for fire extinguishing and for retraction after use, the delivery pipe 22 is configured as a two-section structure, specifically including a fixed section 221 and a rotating section 222. To avoid interference or collision between the first water gun 211 and the wall 11 when it rotates with the rotating section 222, the parameter settings at the first water gun 211 need to meet the following requirements:

[0049]

[0050] The minimum width required for the first water gun 211 to rotate horizontally outside the wall 11 is L_total. This width is related to the length L1 of the first water gun 211, the distance L2 between the mounting base of the first water gun 211 (i.e., the connection point between the first water gun 211 and the rotating section 222) and the wall 11, the thickness L3 of the wall 11, the vertical distance L4 between the axis of the fixed section 221 (i.e., the rotation axis of the rotating section 222) and the wall 11, and the pre-load LB. Figure 6 In this context, L represents the total distance from the axis of the fixed section 221 to the front end of the first water gun 211. The length L1 of the first water gun 211 determines its range of rotation, and the pre-load LB is a calculated allowance to ensure reliable operation of the first water gun 211 in emergency situations. The overall design must guarantee the pre-load LB.

[0051] In this embodiment, the spraying device 20 also includes a gate valve and a drip valve installed on the fixed section 221. The gate valve has a conducting state for opening the delivery pipeline 22 and a blocking state for blocking the delivery pipeline 22. The drip valve is installed between the gate valve and the rotating section 222. The gate valve controls the opening and closing of the delivery pipeline 22 and the amount of water in the delivery pipeline 22. After the spraying operation is completed, the pump room needs to be stopped first, and then the gate valve is closed. After the gate valve is closed, there is residual water in the delivery pipeline 22 between the pipe above the gate valve and the first water gun 211. The drip valve (specifically, a pressure relief valve) can discharge this residual water. The drip valve can regulate the water pressure inside the delivery pipeline 22 to prevent excessive water pressure from damaging the pipeline.

[0052] In addition, considering that there is a large pressure inside the delivery pipe 22 when the first water gun 211 is working, a pipe fixing clip is installed to fix it to the wall 11 to ensure the stability of the delivery pipe 22.

[0053] like Figure 7 As shown, the water gun structure 21 includes a second water gun 212 mounted on top of the wall 11. The second water gun 212 is connected to the inner side of the wall 11 via a mounting bracket 40. The sprinkler device 20 also includes a second shielding bracket 25 covering the outer periphery of the second water gun 212. For the wall 11 with an external mountain retaining wall, the ignition point is high when a wildfire spreads. By directly mounting the second water gun 212 on top of the wall 11, it can spray to a higher position. The second shielding bracket 25 covers the outer periphery of the second water gun 212, which can protect the second water gun 212, especially the connection between the second water gun 212 and the delivery pipe connected to it, to ensure the service life of the second water gun 212.

[0054] like Figure 7 As shown, the mounting bracket 40 includes a triangular support frame 41, a support upright 42, and a support crossbar 43. The triangular support frame 41 is installed on the inner side of the wall 11. The delivery pipe connected to the second water gun 212 is fixed to the support upright 42 and the support crossbar 43 by clamps to counteract the impact force generated by the second water gun 212 during operation. Holes can be drilled in the triangular support frame 41 to rigidly adjust the position of the mounting bracket 40 on the wall 11.

[0055] The structure and function of the second shield 25 are basically the same as those of the first shield 23, and will not be described again here. Both the first shield 23 and the second shield 25 only cover a portion of the structure of the first water gun 211 and the second water gun 212. The spray tip of the first water gun 211 extends outward from the first shield 23 to prevent the first shield 23 from restricting the rotation range of the first water gun 211; the spray tip of the second water gun 212 extends outward from the second shield 25 to prevent the second shield 25 from restricting the rotation range of the second water gun 212.

[0056] Specifically, in this embodiment, the water gun structure 21 may include at least one first water gun 211 and / or at least one second water gun 212. The choice between the first water gun 211 and the second water gun 212 can be made based on the wiring arrangement on the substation wall 11 (referring to the layout of electrical wires) and the external terrain. For a perimeter wall 10 (i.e., wall 11) with an external mountain, the water gun structure 21 is required. Furthermore, when the terrain outside the wall 11 is relatively flat or wiring is required above the wall 11, the first water gun 211 is installed; when the external mountain is relatively high, a protective wall is installed, or no wiring is required above the wall 11, the second water gun 212 is installed. Of course, on the same wall 11, both the first water gun 211 and the second water gun 212 can be installed simultaneously, forming a staggered installation.

[0057] In this embodiment, both the first water gun 211 and the second water gun 212 are structures capable of rotating around their mounting points. The first water gun 211 and the second water gun 212 can be purchased directly from the market, therefore their specific structures will not be described in detail.

[0058] Furthermore, the spacing between adjacent water guns is primarily determined by the coverage area of ​​the water gun itself, ensuring that the final spray range of the water gun structure 21 can cover all the hillsides outside the substation. Of course, in addition to considering the horizontal coverage area of ​​the water gun structure 21, the vertical coverage area and the required distance from the electrified surface also need to be considered. Specifically, the water gun structure 21 must satisfy the following formula:

[0059]

[0060] in,

[0061] L(H) is the distance between the water gun structure 21 and the surrounding electrical equipment at the arrangement height H;

[0062] D an These are the required safe distance values ​​for different voltage levels;

[0063] dwall-out The lateral distance between the outer wall at height H and the external mountain or protective wall is determined for the installation of the water gun structure 21.

[0064] α is the maximum elevation angle of the water gun structure 21;

[0065] h(d wall-out The height difference between the water gun structure 21 at height H and the top of the mountain or protective wall outside the wall 11.

[0066] Since substations built into mountains are typically constructed by excavating spaces within the mountainside, the outer side of wall 11 usually has little or no vegetation. Abundant vegetation only appears at the top of the excavation site, making it easier for wildfires to spread. The aforementioned design ensures that the water jets from the water gun structure 21 are not blocked by this lack of vegetation, allowing them to reach the upper part of the mountain where wildfires are prone to spread.

[0067] In this embodiment, the substation fire protection system also includes a detection device electrically connected to the sprinkler system 20. The detection device can detect the wildfire situation and send detection information to the sprinkler system 20. The detection device is arranged at the location where the first water gun 211 and the second water gun 212 are installed. The detection device can detect the wildfire situation and send the detection information to the sprinkler system 20, thereby causing the sprinkler system 20 to start or stop the water pump, and can control the size of the gate valve to adjust the water output, so as to extinguish the fire or prevent the fire from spreading into the substation.

[0068] Specifically, the detection device can be an image recognition module, which can observe the size of the fire-affected area of ​​the equipment inside and outside the enclosure 10 and feed it back to the control module. The control module controls the opening and closing of the water gun structure according to the existing fire pipeline pressure, the water storage in the pump room, etc., and at the same time controls the opening and closing of the pressure relief valve to maintain the pressure balance inside the pipeline.

[0069] The substation fire protection system also includes a flow control system. To ensure a minimum safety margin of water storage w1 within the substation, the substation maintains a fixed water storage capacity wc. With fire hoses simultaneously spraying water, the water supply is quickly depleted, necessitating timely replenishment of the fire water storage wb. Simultaneously, based on externally detected wildfire conditions, the outward water flow rate C is adjusted. The overall outward water flow rate requirement is as follows: C ≤ wb + wc - w1.

[0070] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0071] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0072] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
