Description

Technical Field

[0001] The invention relates to the field of fire safety teaching aids, in particular to a petroleum storage tank fire extinguishing tactical sand table. Background Art

[0002] With the establishment of the Ministry of Emergency Management, the fire rescue team has embarked on a new path of professionalization and specialization, but at the same time it has also put forward higher requirements on the professionalism and command ability of fire commanders. At present, in the special training of oil tank fires, my country's training methods are still very simple. Due to the constraints of venues and funds, field training is difficult to carry out, and therefore it is difficult to improve the commander's command ability.

[0003] When faced with a complex fire scene, the commander's command and decision-making ability is still an important factor affecting the efficiency of fire fighting. The factors that affect the commander's on-site decision-making at the fire scene are mainly the on-site information processing results and the commander's own command ability. Since oil storage tank fires account for a relatively low proportion of all types of fires in the country and the number of occurrences is relatively low, the commander's experience accumulated through actual combat is limited, and the commander's command ability is limited.

[0004] There are related technologies in the prior art to utilize the auxiliary role of the sand table to improve the commander's command ability, such as the utility model patent with application number "201921868892.1" and name "A simulation teaching sand table for oil storage tank area" and the utility model patent with application number "201921868909.3" and name "A simulation teaching sand table for liquefied hydrocarbon storage tank area". Although they can help commanders improve their abilities to a certain extent, the storage tanks on the sand table are fixed and cannot be disassembled, and the scenes are fixed. When using it for hypothetical operations and desktop simulations, the scenes that can be set are limited, and different scenes cannot be changed. The role they play in the training of fire commanders is limited, and the teaching effect is poor.

[0005] Therefore, people are in urgent need of a petroleum storage tank fire extinguishing tactical sand table with good teaching effect. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a tactical sand table for oil tank fire fighting to solve the problems existing in the prior art. The inclination angle of the floating plate can be adjusted by adjusting the pulling rope, simulating the situation where the floating plate is tilted at different angles in a real fire, and then teaching how to extinguish the fire when the floating plate is tilted at different angles, thereby improving the teaching effect.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Please refer to Figures 1 to 3 As shown, a petroleum storage tank fire extinguishing tactical sand table is provided, including a sand table surface 1 and a plurality of simulated oil tanks 2, the plurality of simulated oil tanks 2 are all arranged on the sand table surface 1, the plurality of simulated oil tanks 2 include intact vaulted roof tanks, intact external floating roof tanks, intact internal floating roof tanks, oil tanks with inwardly curved tank walls, internal floating roof tanks with curled edges on floating plates, and oil tanks equipped with complete accessories, the accessories being ladders, railings, etc. The specific transparent material can be selected from acrylic plates, which can enhance the commander's awareness of whether the tank body is damaged while enabling the commander to understand the internal structure of various oil tanks and corresponding accessories, thereby improving the commander's knowledge reserve and ensuring that the tank body is intact. A number of hooks 19 are arranged around the outer wall of the external floating roof tank. A number of pulling ropes 20 are evenly connected around the floating plate of the intact external floating roof tank. The pulling ropes 20 can be fishing lines. The pulling ropes 20 can be glued to the floating plate or holes can be opened on the floating plate. The pulling ropes 20 are passed through the holes and bound to the floating plate. The hooks 19 correspond to the pulling ropes one by one. The pulling ropes 20 pass through the top tank mouth of the intact external floating roof tank and are connected to the hooks 19. The inclination angle of the floating plate can be adjusted by pulling the pulling rope, thereby simulating the situation where the floating plate is tilted at different angles in a real fire, and then teaching how to extinguish a fire when the floating plate is tilted at different angles, thereby improving the teaching effect.

[0030] Due to the different number of oil tanks in different oil tank areas, several intact arch roof tanks, intact external floating roof tanks and intact internal floating roof tanks can be set up. However, since the oil tanks with inward curved tank walls, internal floating roof tanks with curled edges on the floating plates and oil tanks equipped with complete accessories are only for identification and teaching purposes, they can be set to one.

[0031] In order to more fully simulate the real situation, water can be poured into the simulated oil tank 2 to simulate the oil during teaching.

[0032] The oil tank fire extinguishing tactical sand table also includes simulated fixed fire-fighting facilities and simulated rescue facilities. The upper surface of the sand table surface 1 is a magnetic adsorption area as a whole. Several simulated oil tanks 2, simulated fixed fire-fighting facilities and simulated rescue facilities are all adsorbed on the magnetic adsorption area by magnetic force. The magnetic adsorption method can be: the sand table surface 1 is iron or other metals that can be attracted to magnets, and magnets are pasted on the bottom of several simulated oil tanks 2, simulated fixed fire-fighting facilities and simulated rescue facilities, or magnets are directly embedded in the bottom of several simulated oil tanks 2, simulated fixed fire-fighting facilities and simulated rescue facilities during production; the sand table surface 1 can also be made of a material that does not affect the attraction of the magnet, for example Aluminum alloy, a magnet plate 3 with the same area as the bottom of the sand table surface 1 is pasted, or several small magnet blocks are used to cover the bottom of the sand table surface 1, and magnets used to attract each other with magnet plates 3 at the bottom of the sand table surface 1 are pasted on the bottom of several simulated oil tanks 2, simulated fixed fire-fighting facilities and simulated rescue facilities. Since several simulated oil tanks 2, simulated fixed fire-fighting facilities and simulated rescue facilities are all adsorbed on the magnetic adsorption area by magnetic force, the positions of the simulated oil tanks 2, simulated fixed fire-fighting facilities and simulated rescue facilities on the sand table surface 1 can be adjusted by directly taking them away, thereby realizing flexible disassembly of components and building a variety of scenes to improve teaching effects.

[0033] A smoke ejector 4 for simulating smoke in a fire scene is arranged on the sand table surface 1. A dry ice spray machine can be selected as the smoke ejector 4. The smoke ejector 4 is used to simulate the smoke scene in a fire situation, which further improves the realism of the sand table simulation, increases the scene control range of the sand table, and further improves the teaching effect.

[0034] A fence 5 is extended upward from the four sides of the sand table surface 1 to intercept smoke. Several groups of indicator lights 6 are evenly arranged on the inner wall of the fence 5. The indicator lights 6 include yellow lights for simulating the color of flames under normal combustion conditions, white lights for simulating the color of flames when heavy oil burns and boils and splashes, and blue lights for simulating the color of flames in explosion-prone situations. The indicator lights 6 are used to simulate the combustion conditions in a fire, which further improves the realism of the sand table simulation, increases the scene control range of the sand table, and further improves the teaching effect.

[0035] The sand table surface 1 is provided with a speaker 7 for simulating the sound of boiling, splashing or explosion. The use of the speaker 7 to simulate the sound of boiling, splashing or explosion further improves the realism of the sand table simulation, increases the scene control range of the sand table, and further improves the teaching effect.

[0036] The simulated fixed fire-fighting facilities include fire passages 8, foam stations 9, fire pools 10, fire hydrants 11, firebreaks 12 and sprinkler systems 13. All components are magnetically adsorbed on the magnetic adsorption area. In order to make the scene more realistic, the scale ratio of the fire passages 8 and the firebreaks 12 is the same as that of the simulated oil tank 2, for example, 1:100. In order to make small components clearer, the scale ratio of the fire hydrants 11 and the sprinkler system 13 is greater than that of the simulated oil tank 2. For example, the scale ratio of the fire hydrants 11 is 1:10, and the scale ratio of the sprinkler system 13 is 1:30. The sprinkler system 13 includes a cooling water sprinkler system, a semi-fixed water sprinkler system, a fixed foam fire extinguishing facility, a semi-fixed liquid upper spray fire extinguishing facility and a semi-fixed liquid lower spray fire extinguishing facility. Several components included in the sprinkler system 13 can be set to increase the scope of the sand table simulation. Multiple fire hydrants 11 can be set and divided into foam fire hydrants and water source fire hydrants.

[0037] The fire passage 8 includes several groups of strip passages of different widths, each group includes at least four strip passages, which are used to enclose fire passages 8 of different widths. On this basis, since the slope is an important factor affecting the parking of the fire truck 15 and the selection of positions, several additional strip passages for simulating ramps can be added to each group of strip passages, for example, several strip passages with angles of 5°, 10° or 15° can be added to simulate ramps.

[0038] In order to construct firebreaks 12 of different sizes, the entire firebreak 12 can be assembled similar to Lego blocks, and the bottoms of the blocks used to form the bottom layer among the blocks are magnetically adsorbed on the magnetic adsorption area, and the blocks used to form the bottom layer are set in a different color from the upper blocks for distinction.

[0039] The simulated rescue facilities include firefighters 14 and fire trucks 15. The fire trucks 15 include a vehicle body and on-board equipment. In order to make the firefighters 14 and the on-board equipment clearer, the scaling ratios of the firefighters 14 and the on-board equipment are greater than the scaling ratio of the simulated oil tank 2. For example, the scaling ratio of the firefighters 14 is 1:35, and the scaling ratio of the on-board equipment is 1:10. The scaling ratio of the vehicle body is the same as that of the simulated oil tank 2, for example, 1:100. Several firefighters 14 can be made and divided into commanders, fighters, safety officers, water supply officers, communicators and other occupations, and distinguished by different colors.

[0040] The fire fighting vehicles 15 include water tank fire trucks, foam fire trucks, aerial spray trucks, aerial platform trucks, foam transport trucks, emergency rescue vehicles, communication command vehicles and logistics support vehicles, etc. The on-board equipment includes mobile water cannons, mobile foam cannons, mobile water guns, foam pipe guns, foam hook pipes and water distributors, etc.

[0041] In order to facilitate the transfer of the sand table surface 1, a plurality of support legs 16 are provided on the bottom surface of the sand table surface 1, and walking wheels are provided at the bottom of the support legs 16.

[0042] A storage tray 17 for holding various simulation components is provided below the sand table surface 1, so as to fully utilize the space and improve the space utilization rate.

[0043] The sand table surface 1 is also provided with a simulated pipe gallery 18, a simulated adjacent tank area, a simulated chemical area or a simulated high slope, which are used to simulate the buildings around the oil tank area.

[0044] Grid grooves can be opened on the entire upper surface of the sand table surface 1. The grid is a square grid, and each grid represents a certain distance. The specific distance represented is determined artificially, that is, the grid grooves serve as marking scales.

[0045] In actual use, various components are magnetically adsorbed on the sand table surface 1 according to needs, and assembled into the required scenes to teach the commanders.

[0046] Adaptive changes made according to actual needs are all within the protection scope of the present invention.
