Technical Field

[0001] The invention relates to the field of fire prevention and extinguishing of coal piles, and in particular to a fire prevention and extinguishing grouting equipment for coal piles at ports. Background Art

[0002] Coal stacking at ports mainly involves the storage, loading and unloading, and transportation of coal, and is an important part of the port's bulk cargo business. In the process of coal stacking at ports, large mechanical equipment is usually used, such as stackers and reclaimers, dumpers, etc. These equipment can efficiently unload coal from cargo ships and stack them in designated yards. The yard is an area of ​​the port specifically used to store bulk cargo. For bulk cargo such as coal, the yard needs to have good drainage performance and foundation bearing capacity to ensure the safe storage of coal.

[0003] If coal spontaneously combusts due to weather temperature, the coal needs to be extinguished. In the prior art, the coal is extinguished by spraying a fire extinguishing agent. However, the fire extinguishing agent is sprayed onto the surface of the coal by a machine and is not easy to enter the interior of the coal. Moreover, during the fire extinguishing, the spontaneous combustion of the coal continues to spread, and the efficiency is low.

[0004] Therefore, it is necessary to propose a port coal pile fire prevention and extinguishing spraying equipment to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a port coal pile fire prevention and extinguishing spraying equipment to solve the problem that in the prior art, the fire extinguishing agent is sprayed on the coal surface by a machine and is not easy to enter the coal, and the spontaneous combustion of the coal continues to spread during the fire extinguishing, which is inefficient.

[0007] Preferably, a winding motor is fixed to one side of the connecting frame, and a driving shaft of the winding motor is fixedly connected to one end of the winding shaft.

At the same time, by controlling the descending height of the descending plate, the fire can be extinguished at different depths inside the coal, with relatively high accuracy.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The present invention provides asFigures 1 to 3 A kind of spraying equipment for preventing and extinguishing fire on port coal piles as shown in the figure, including sliding tracks 1. There are two sliding tracks 1 arranged in parallel, and the two sliding tracks 1 are respectively enclosed on both sides of the coal pile. Mobile frames 2 are slidably fitted on both sliding tracks 1. Support frames 3 are fixed at the tops of the two mobile frames 2, and a top plate 6 is fixed between the tops of the two support frames 3, so that the mobile frames 2 move on the corresponding sliding tracks 1, thereby enabling the structures on the mobile frames 2 to move on the coal pile and reach the designated location for fire extinguishing work.

[0020] In order to solve the problem in the prior art that when extinguishing coal fires by spraying fire extinguishing agents, the fire extinguishing agents are sprayed on the surface of the coal by a machine, it is not easy to enter the interior of the coal, and during fire extinguishing, the spontaneous combustion of the coal continues to spread, with low efficiency. Therefore, a connecting frame 7 is fixed at the bottom end of the top plate 6. A winding shaft 8 is rotatably connected inside the connecting frame 7. A connecting rope 10 is wound around the winding shaft 8. The bottom end of the connecting rope 10 is connected to a descending plate 5. A winding motor 9 is fixed on one side of the connecting frame 7, and the driving shaft of the winding motor 9 is fixedly connected to one end of the winding shaft 8.

[0021] After the winding motor 9 is started, the winding shaft 8 can drive the connecting rope 10 to be released and wound, so that the connecting rope 10 drives the descending plate 5 to descend and ascend. The winding motor 9 can use a motor that can rotate in both forward and reverse directions, so as to realize the release and winding work of the connecting rope 10.

[0022] A plurality of fire extinguishing spraying nozzles 12 are arranged along the length direction at the bottom end of the descending plate 5. Insertion plates 11 are fixed on both sides of the descending plate 5. The two insertion plates 11 are both L-shaped, and the lengths of the two insertion plates 11 are longer than the length of the fire extinguishing spraying nozzles 12.

[0023] In the actual operation of the present invention, when spontaneous combustion occurs in the coal area, the whole device can be moved to the spontaneous combustion area through the movement of the mobile frame 2, and by starting the winding motor 9, the descending plate 5 descends. At this time, the insertion plates 11 on both sides of the descending plate 5 will insert into both sides of the coal spontaneous combustion area by their own gravity, preventing the spontaneous combustion area from spreading to both sides. At the same time, after the descending plate 5 descends, it will drive the fire extinguishing spraying nozzles 12 to insert into the coal interior to extinguish the spontaneous combustion area, avoiding that the fire extinguishing agent is only sprayed on the surface of the coal and cannot effectively extinguish the fire.

[0024] At the same time, the blocking effect of the two insertion plates 11 can prevent the fire extinguishing agent from spreading to both sides of the spontaneous combustion area, resulting in a decrease in the concentration of the fire extinguishing agent, improving the accuracy and efficiency of fire extinguishing, enabling the fire extinguishing agent to spread in the spontaneous combustion area between the two insertion plates 11. At the same time, by controlling the descending height of the descending plate 5, the coal at different depths inside can be extinguished, with relatively high accuracy.

[0025] If the spontaneous combustion area is on the coal surface, the fire extinguishing spraying head 12 can be simply brought close, and there is no need to insert it into the coal interior. The fire extinguishing spraying head 12 can spray fire extinguishing agents, such as existing combustion-blocking fire extinguishing agents like inhibitor and Prate fire prevention and extinguishing materials.

[0026] It should be noted that the plug board 11 can be telescopically connected to the descending plate 5 through an electric push rod, which is used to expand and contract the distance between the two plug boards 11 to facilitate adapting to the size of the actual spontaneous combustion area.

[0027] Sliding grooves 4 are provided on the opposite sides of the two support frames 3. The two sliding grooves 4 are distributed along the height direction of the corresponding sliding groove 4, and the two ends of the descending plate 5 are respectively slidably fitted inside the corresponding sliding grooves 4.

[0028] One side of the top end of the descending plate 5 is connected with an input pipe 13. The input pipe 13 is connected with a plurality of fire extinguishing spraying heads 12. The bottom ends of the plurality of fire extinguishing spraying heads 12 are conical, which can facilitate the insertion of the fire extinguishing spraying heads 12 into the gaps of the coal. Temperature sensors are fixed on the outer sides of the plurality of fire extinguishing spraying heads 12.

[0029] Wear-resistant coatings are applied on the outer sides of the plurality of fire extinguishing spraying heads 12 and the plug board 11 to increase the service life and wear resistance of the fire extinguishing spraying heads 12 and the plug board 11.
