Description

Technical Field

[0001] The present application relates to the technical field of high-position fire extinguishing for coal yards, and particularly to a top fire extinguishing device for a dry coal yard that utilizes rainwater. Background Art

[0002] During long-term operation, the coal dust contained in the air in the dry coal yard is dispersed everywhere in the space, resulting in a large amount of coal dust accumulating on the upper surface of the top steel frame and positions such as the top pipeline trough boxes. As time goes by, the risk of spontaneous combustion increases. For extinguishing this type of fire, if a fire truck enters the interior for extinguishing, since there are usually large coal piles in the dry coal yard and there is no vehicle flow path, the operation range of the fire truck is small. If a fire truck is used for external extinguishing, due to the influence of the surface cover plate, the spray cannot directly contact the flame. If a drone is used, due to the large metal covering structure, the control signal of the drone equipment may be affected by the shielding of the on-site steel frame, and the internal drone control signal is greatly affected. Moreover, generally, the weight carried by a drone is not higher than 50 kg, and the fire extinguishing ability is limited. Summary of the Invention

[0003] The present application provides a top fire extinguishing device for a dry coal yard that utilizes rainwater to solve the problem in the prior art that it is difficult to quickly extinguish the spontaneous combustion of coal dust on the top of the dry coal yard.

[0004] The present application provides a top fire extinguishing device for a dry coal yard that utilizes rainwater, including: A water collection assembly, arranged on the shed frame, forming a water collection cavity and a water collection port communicating with the water collection cavity; A spray assembly, including a plurality of them, respectively installed on the water collection assembly; A pipeline, arranged in the water collection cavity, one end communicating with a water pump in the water collection cavity, and the other end communicating with the spray assembly.

[0005] In a possible design, the water collection assembly includes a water collection tank and a diversion pipe. The water collection tank is installed below the shed frame. The lower end of the diversion pipe communicates with the water collection tank, and the upper end of the diversion pipe extends above the shed frame. The upper end of the diversion pipe forms the water collection port.

[0006] In a possible design, the water collection port is in the shape of an outward-expanded horn; and / or, a filter screen is arranged at the water collection port.

[0007] In a possible design, the length direction of the water collection tank is consistent with the length direction of the shed frame, and a plurality of diversion pipes are uniformly arranged along the length direction of the water collection tank.

[0008] In a possible design, a fixing pipe extending obliquely upward is arranged on the water collection tank, and an adjusting pipe is arranged at the end of the fixing pipe. The included angle between the axis of the adjusting pipe and the axis of the fixing pipe can be adjusted.

[0009] In a possible design, the spraying assembly includes: A fixed seat, installed on the inner wall of the adjusting pipe; A rotating seat, rotatably engaged with the fixed seat. A first flow channel is provided on the rotating seat, and the first flow channel is communicated with the pipeline; A nozzle, installed on the rotating seat. A second flow channel is provided on the nozzle, and the second flow channel is communicated with the first flow channel. When water flows out from the second flow channel, a moment can be generated to drive the rotating seat to rotate around its own axis.

[0010] In a possible design, a third flow channel is provided on the nozzle, and the axis of the third flow channel is arranged along the tangent direction of the rotating seat.

[0011] In a possible design, it further includes a water bag, which is suspended at intervals below the water collecting tank. A plurality of water discharge ports are provided at the lower end of the water collecting tank, and the water in the water collecting tank can flow into the corresponding water bag through the corresponding water discharge port.

[0012] In a possible design, the water collecting tank is in a horizontally placed cylindrical shape. Sleeve rings corresponding to the water discharge ports are provided at intervals on the outer wall of the water collecting tank. The water bag is suspended on the sleeve ring, and a sealing part is provided on the inner wall of the sleeve ring. The sleeve ring can move along the length direction of the water collecting tank to block or avoid the water discharge port with the sealing part.

[0013] In a possible design, a threaded hole is provided on the sleeve ring, and a threaded rod is inserted into the threaded hole. The threaded rod is rotatably installed on the bearing seat of the shed frame. The axial direction of the threaded rod is parallel to the length direction of the water collecting tank, and the rotation of the threaded rod can drive the sleeve ring to move along its axial direction.

[0014] The beneficial effects of this application are as follows: For the top fire extinguishing device of the dry coal shed in this application, by using the water collecting port extending out of the top of the shed frame of the dry coal shed, rainwater is filtered and collected into the water collecting cavity, and the rainwater is used for fire extinguishing without the need to use additional water resources, which is beneficial to saving water and has a strong water storage capacity. This device can cover each area position on the top of the dry coal shed, and the fire extinguishing spray is carried out from the inside of the shed frame, and the fire extinguishing efficiency is significantly improved compared with that of drones, etc.

In the case of an emergency fire, the spraying assembly sprays the self-igniting structure on the top with the water in the water collecting cavity to achieve rapid fire extinguishing in the first time.

[0016] By installing the water collecting tank below the shed frame, the water collecting tank applies a downward force to the shed frame, which is equivalent to adding support columns on the ground below the shed frame to make the shed frame firmly hold on the ground, which is beneficial to preventing the shed frame from tipping over in strong wind weather.

[0017] By opening a plurality of water discharge openings at the lower end of the water collecting tank and arranging water bags at each water discharge opening, when strong wind weather occurs, water is injected into each water bag, and the free swing of each water bag reduces the amplitude of the inclined swing of the shed frame to one side, thereby protecting the shed frame and preventing it from being blown down by strong winds.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0021] The following will describe, in conjunction with Figures 1 - 6 , a dry coal shed top fire extinguishing device that utilizes rainwater provided in the embodiments of the present application.

[0022] Referring to Figure 1 As shown, the dry coal shed includes a cover plate 920 and a shed frame 910. Generally, there are multiple coal piles 930 in the dry coal shed, and they are separated by a bucket wheel machine operation platform 940. The dry coal shed top fire extinguishing device that utilizes rainwater provided in the embodiments of the present application is suspended on the shed frame 910. The device includes a water collection assembly 100, a spraying assembly 200, and a pipeline 300. The water collection assembly 100 is arranged on the shed frame 910, and a water collection cavity 111 and a water collection port 121 communicating with the water collection cavity 111 are formed. Specifically, the water collection assembly 100 includes a water collection tank 110 and a diversion pipe 120. A plurality of lifting lugs are arranged at intervals on the outer wall of the water collection tank 110. At each lifting lug, at least one suspension rod 950 is correspondingly arranged. One end of the suspension rod 950 is connected to the lifting lug, and the other end is fixedly connected to the shed frame 910, so as to fix the water collection tank 110 below the shed frame 910. In some specific embodiments, the water collection tank 110 is in the shape of a horizontally placed cylinder, the length direction of the water collection tank 110 is consistent with the length direction of the shed frame 910, and a plurality of diversion pipes 120 are uniformly arranged along the length direction of the water collection tank 110. The lower end of each diversion pipe 120 is respectively communicated with the water collection cavity 111, the upper end of the diversion pipe 120 extends above the shed frame 910, and the upper end of the diversion pipe 120 forms the water collection port 121. This can facilitate installation and reduce the number of water collection tanks 110 at the same time. In some embodiments, three water collection tanks 110 are arranged in the shed frame 910. Specifically, one water collection tank 110 is fixed at the highest position in the center of the shed frame 910, and one water collection tank 110 is symmetrically fixed on each of the opposite sides. This is beneficial to make the spraying range of the water collection tank 110 cover the entire shed frame 910. In some embodiments, the water collection port 121 is in the shape of an outward-expanded horn, which is beneficial to increase the water collection area. A filter screen 113 is arranged at the water collection port 121, which can prevent impurities in the air from entering the water collection tank 110 from the water collection port 121.

[0023] Referring to Figure 2As shown, in the embodiments of the present application, a plurality of spraying components 200 are respectively installed on each water collecting tank 110. A pipeline 300 is arranged in the water collecting cavity 111 of the water collecting tank 110. One end of the pipeline 300 is communicated with a water pump 400 in the water collecting cavity 111, and the other end is communicated with the spraying component 200. Specifically, the pipeline 300 includes a hard pipe 310 and a flexible pipe 320. The hard pipe 310 includes a vertical section and a horizontal section that are communicated with each other. The lower end of the vertical section is connected to the water pump 400, the upper end of the vertical section is connected to the horizontal section, and a plurality of interfaces are uniformly arranged on the horizontal section. Each interface is respectively connected to a flexible pipe 320, and the other end of the flexible pipe 320 is connected to the corresponding spraying component 200. In this way, the water pump 400 can transport the water in the water collecting cavity 111 to each spraying component 200 through the hard pipe 310 and the flexible pipe 320 respectively.

[0024] Referring to Figure 2 As shown, in some specific embodiments, a fixing pipe 510 extending obliquely upward is arranged on the water collecting tank 110. An adjusting pipe 520 is arranged at the end of the fixing pipe 510, and the flexible pipe 320 passes through the fixing pipe 510 and the adjusting pipe 520. The included angle between the axis of the adjusting pipe 520 and the axis of the fixing pipe 510 can be adjusted. Specifically, the diameter of the adjusting pipe 520 is larger than the diameter of the fixing pipe 510. Threaded shafts are symmetrically fixed on the outer wall of the fixing pipe 510. Axial holes are symmetrically arranged at the ends of the adjusting pipe 520. The outer ends of the threaded shafts can pass through the axial holes and be fixed by fixing nuts. In this way, the included angle between the adjusting pipe 520 and the fixing pipe 510 can be adjusted, which is convenient for adjusting the spraying direction of the spraying component 200.

[0025] Referring to Figure 3 、 Figure 4As shown, in some specific embodiments, the spraying assembly 200 includes a fixed seat 210, a rotating seat 220, and a nozzle 230. The fixed seat 210 and the rotating seat 220 are respectively annular seats. The fixed seat 210 is fixed to the inner wall of the adjusting pipe 520 through a flange. Both ends of the fixed seat 210 have flange plates. One flange plate is fixedly connected to the end flange of the pipeline 300 through bolts, and the other flange plate is fixedly connected to the end flange of the fixed seat 210 through bolts. The rotating seat 220 is coaxially rotatably engaged with the fixed seat 210 through a bearing. A first flow channel 221 is provided on the rotating seat 220. When the rotating seat 220 rotates, the first flow channel 221 is always in communication with the pipeline 300. The nozzle 230 is installed on the rotating seat 220. A second flow channel 231 is provided on the nozzle 230. The second flow channel 231 is in communication with the first flow channel 221. When water flows out from the second flow channel 231, a moment can be generated to drive the nozzle 230 to drive the rotating seat 220 to rotate around its own axis. Specifically, a third flow channel 232 is provided on the nozzle 230. The axis of the third flow channel 232 is arranged along the tangent direction of the rotating seat 220. In this way, when water flows through the second flow channel 231, part of the water will flow into the third flow channel 232 and spray out from the third flow channel 232. Since the axis of the third flow channel 232 is along the tangent direction of the rotating seat 220, and inertia is generated when the water flows out. When the water leaves the nozzle 230, the inertia will cause the water to maintain a certain speed after flowing out. This inertial force will push the nozzle 230 to rotate in the reverse direction, thereby enabling the automatic rotation of the nozzle 230 and increasing the spraying area of the nozzle 230.

[0026] Referring to Figure 5 、 Figure 6 As shown, in some specific embodiments, the device further includes a water bag 600. The material of the water bag 600 is soft, such as a rubber bag, etc. It can swing left and right due to external forces after being filled with water. The water bag 600 is suspended at intervals below the water collecting tank 110. A plurality of water discharge ports 112 are provided at intervals at the lower end of the water collecting tank 110. The water in the water collecting tank 110 can flow to the corresponding water bag 600 through the corresponding water discharge ports 112. Specifically, a collar 700 corresponding to the water discharge port 112 is sleeved on the outer wall of the water collecting tank 110 at intervals. A hanging buckle is provided on the outer side of the collar 700. The upper end of the water bag 600 has a hanging hole. By threading the hanging hole through the hanging buckle, the water bag 600 can be suspended on the collar 700. A sealing portion 710 is provided on the inner wall of the collar 700. The sealing portion 710 is a rubber pad. When the collar 700 moves along the length direction of the water collecting tank 110 and reaches the position of the water discharge port 112, it can seal the water discharge port 112; when the collar 700 moves along the length direction of the water collecting tank 110 to avoid the water discharge port 112, it can open the water discharge port 112 to allow the water in the water collecting tank 110 to flow into the water bag 600.

[0027] Specifically, a thread hole is opened on the ring 700, and a screw rod 800 is passed through the thread hole. The screw rod 800 is rotatably installed on the bearing seat of the frame 910. The axial direction of the screw rod 800 is parallel to the length direction of the water collecting tank 110. The end of the screw rod 800 can be connected to the motor transmission. The motor can drive the screw rod 800 to rotate and then drive the ring 700 to move along the axial direction of the water collecting tank 110.

[0028] When it is windy, the motor drives the screw 800 to rotate and then drives the ring 700 to move along the axial direction of the water collecting tank 110 to avoid the drain port 112. At this time, the drain port 112 is opened, and the water in the water collecting tank 110 flows into the water bag 600. Due to the blowing of the wind, each water bag 600 will swing freely, which can effectively reduce the amplitude of the tilting swing of the scaffolding 910 to one side, thereby protecting the scaffolding 910 and preventing it from being blown down by the strong wind.
