Description

Technical Field

[0001] This utility model relates to the field of coal mine safety production technology, specifically to a fire prevention and extinguishing material spraying equipment for goaf areas. Background Technology

[0002] Spontaneous combustion of coal in goaf areas is one of the major hidden dangers to coal mine safety. According to the different heat sources caused by the fire in the mine, it can be divided into two categories: external fires and spontaneous combustion of coal. Spontaneous combustion in coal mines is very serious in my country, with spontaneous combustion in goaf areas accounting for 60% of internal fires. The harsh conditions in underground coal mines, such as high temperature, high humidity, and poor heat dissipation, pose a serious threat to underground production safety. When a spontaneous combustion accident occurs in a goaf area, it is necessary to use spraying equipment to spray fire extinguishing materials to extinguish the fire.

[0003] The device can spray fire extinguishing materials onto the goaf to extinguish the fire. However, if the device is used for a long time to spray the fire extinguishing materials into the goaf, the materials may cause blockages in the delivery pipeline, which will affect the delivery of the fire extinguishing materials and thus affect the fire extinguishing effect of the device, which will also be detrimental to the use of personnel. Utility Model Content

[0004] The purpose of this utility model is to provide a fire-fighting material spraying device for goaf areas, in order to solve the problem mentioned in the background art that, while the device can spray fire-fighting materials onto the goaf area to achieve a fire-fighting effect, if the device is used for a long time to spray the fire-fighting materials, the fire-fighting materials are prone to causing blockages in the delivery pipeline, which will affect the delivery of the fire-fighting materials, thereby affecting the fire-fighting effect of the device and making it unsuitable for personnel to use.

[0025] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0026] Example 1:

[0027] The fire prevention and extinguishing material spraying equipment for goaf areas provided in this application includes a storage tank 1 and a spraying mechanism 3; a stirring mechanism 2 is installed inside the storage tank 1, a spraying mechanism 3 is installed on the top of the storage tank 1, and a processing mechanism 4 is installed between the spraying mechanisms 3 on the top of the storage tank 1.

[0028] The processing mechanism 4 includes an air supply device 401, a hose 402 and a valve 403. An air supply device 401 is installed between the top spraying mechanism 3 of the storage tank 1. A hose 402 is installed at the output end of the air supply device 401. A valve 403 is installed on the outside of the hose 402.

[0029] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the storage tank 1 stores fire extinguishing materials. The stirring mechanism 2 is used to stir the fire extinguishing materials inside the storage tank 1 to prevent them from clumping. The spraying mechanism 3 is used to transport and spray the fire extinguishing materials inside the storage tank 1. The processing mechanism 4 is used to process the inside of the conveying pipe of the spraying mechanism 3. The air supply device 401 is a fan. The air supply end of the air supply device 401 is connected to the conveying pipe of the spraying mechanism 3 through the hose 402. When it is necessary to process the inside of the conveying pipe of the spraying mechanism 3, the valve 403 is opened and the air supply device 401 works to generate air force. Then the air is blown into the inside of the conveying pipe of the spraying mechanism 3 through the hose 402, which can then purge the inside of the conveying pipe to prevent blockage and affect the delivery of fire extinguishing materials.

[0030] Furthermore, the spraying mechanism 3 includes a power pump 301, a connecting pipe 302, and a spray pipe 303. The power pump 301 is installed on the top of the storage tank 1. The connecting pipe 302 is installed at the output end of the power pump 301. Two sets of spray pipes 303 are rotatably installed on the top of the power pump 301. One end of the connecting pipe 302 is connected to the spray pipe 303.

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, in order to deliver the fire extinguishing material, the input end of the power pump 301 is connected to the storage tank 1, and the output end of the power pump 301 is connected to the nozzle 303 through the connecting pipe 302. The power pump 301 works to deliver the fire extinguishing material inside the storage tank 1 to the inside of the nozzle 303 through the connecting pipe 302. When the fire extinguishing material is sprayed out from the inside of the nozzle 303, the fire extinguishing material can be sprayed inside the goaf.

[0032] Furthermore, a telescopic rod 5 is rotatably mounted on the top of the power pump 301, and a nozzle 303 is rotatably connected to the moving end of the telescopic rod 5.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, in order to adjust the angle at which the nozzle 303 sprays the extinguishing material, one end of the telescopic rod 5 is rotatably connected to the top of the power pump 301, and the other end is rotatably connected to the nozzle 303. One end of the nozzle 303 is rotatably connected to the top of the power pump 301. When the telescopic rod 5 works, the telescopic end of the telescopic rod 5 will drive the nozzle 303 to move. At this time, the nozzle 303 will rotate with the connection point with the power pump 301 as the fulcrum, thereby adjusting the angle at which the nozzle 303 sprays the extinguishing material.

[0034] Furthermore, a connecting cover 6 is rotatably mounted on one end of the nozzle 303, and a fixing pin 601 is installed inside the nozzle 303 near the connecting cover 6;

[0035] Specifically, such as Figure 4 As shown, in order to facilitate workers to better handle the fire extinguishing material inside the nozzle 303, by moving the fixing pin 601, when one end of the fixing pin 601 moves out of the inside of the connecting cover 6, the worker can rotate the connecting cover 6 to open it from the inside of one end of the nozzle 303, which makes it convenient for workers to operate and handle the inside of the nozzle 303.

[0036] Furthermore, a heating assembly 101 is installed on the inner wall of storage tank 1;

[0037] Specifically, such as Figure 1 As shown, in order to prevent the fire extinguishing materials stored inside the storage tank 1 from clumping due to moisture, the heating component 101 is composed of heating wires. The heating component 101 converts electrical energy into heat energy, which can heat the fire extinguishing materials inside the storage tank 1 to prevent them from clumping due to moisture and affecting the delivery of fire extinguishing materials by the spraying mechanism 3.

[0038] Furthermore, the stirring mechanism 2 includes a drive gear 201, a transmission gear 202, and a crushing rod 203. The drive gear 201 is rotatably mounted inside the storage tank 1. The crushing rod 203 is mounted at both ends of the storage tank 1 near the drive gear 201. The transmission gear 202 is mounted on the outside of the crushing rod 203. The drive gear 201 and the transmission gear 202 are driven by gears.

[0039] Specifically, such as Figure 1 As shown, in order to disperse the fire extinguishing material inside the storage tank 1, the drive gear 201 consists of a motor assembly and a transmission disc. The output end of the motor assembly is connected to the transmission disc, which is existing technology. By rotating the drive gear 201, it can drive the transmission gear 202, thereby driving the breaking rod 203 to rotate. By rotating the breaking rod 203, the fire extinguishing material inside the storage tank 1 can be dispersed.

[0040] Furthermore, an anti-slip seat 102 is installed at the bottom of storage tank 1;

[0041] Specifically, such as Figure 1 As shown, in order to facilitate the fixed use of storage tank 1, workers can place storage tank 1 on a vehicle for installation and use according to the usage situation. The anti-slip seat 102 can improve the anti-slip performance of storage tank 1 when it is placed, and prevent its movement from affecting the use of personnel.

[0042] Furthermore, a weighing sensor 103 is installed at the bottom of the storage tank 1;

[0043] Specifically, such as Figure 1 As shown, in order to monitor the fire extinguishing materials stored inside the storage tank 1, the weight of the fire extinguishing materials stored inside the storage tank 1 can be monitored by the weighing sensor 103. When the value detected by the weighing sensor 103 is lower than the set value, the staff can be reminded by the external controller so that the staff can replenish the fire extinguishing materials inside the storage tank 1 in a timely manner.

[0044] Working principle: The drive gear 201 rotates and can be geared to the transmission gear 202, thereby driving the breaking rod 203 to rotate. The rotation of the breaking rod 203 can break up the fire extinguishing material inside the storage tank 1. Then, the power pump 301 works to transport the fire extinguishing material inside the storage tank 1 to the inside of the nozzle 303 through the connecting pipe 302. When the fire extinguishing material is sprayed out from the inside of the nozzle 303, it can be sprayed to extinguish the fire inside the goaf.

[0045] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
