Description
Technical Field
[0001] This invention relates to the field of tunnel fire protection technology, and in particular to a control system for a high-level fire water tank in tunnels. Background Technology
[0002] A tunnel is an engineering structure buried underground, representing a form of human utilization of underground space. The structure of a tunnel consists of two parts: the main structure and auxiliary equipment. The main structure comprises the tunnel body and portals, while auxiliary equipment includes passing bays, fire-fighting facilities, emergency communication systems, and drainage systems. Longer tunnels also have specialized ventilation and lighting equipment.
[0003] In traffic tunnels, elevated fire-fighting water tanks are needed for fire prevention and extinguishing. However, in the mountainous areas of northern China, these tanks are built on mountaintops at high altitudes. In winter, the water in these tanks is prone to freezing, making it difficult to drain the water quickly during firefighting. Furthermore, since these tanks are located on mountaintops, the water is mostly drawn from natural sources such as wells and rivers. These water sources contain a large number of impurities and microorganisms, leading to bacterial growth, algae, moss, and plankton proliferation. This increases the turbidity of the water, deteriorates the water quality, and causes it to smell bad. There may even be biological slime and large floating objects in the water, which may cause blockages in some equipment of the fire protection system.
[0004] Therefore, it is necessary to provide a new control system for elevated fire-fighting water tanks in tunnels to solve the above-mentioned technical problems. Summary of the Invention

[0014] Preferably, an inspection port and a vent pipe are provided at the top of the water tank, and one end of the vent pipe has a curved sidewall and an opening facing downwards.
[0015] Compared with related technologies, the tunnel high-level fire water tank control system provided by the present invention has the following beneficial effects:
[0016] This invention provides a control system for a high-level fire-fighting water tank in a tunnel. When water is stored in the tank, impurities such as silt and sand in the water move downwards and settle at the bottom of the tank. At regular intervals, a second water pump is turned on. The operation of the second water pump generates suction inside the suction pipe, causing water at the bottom of the tank to pass through the gauze layer and the filter screen and enter the interior of the suction pipe. The sediment at the bottom of the tank moves towards the collection tank, facilitating the sediment in the tank to fall into the collection tank. The operation of the second water pump transports the water at the bottom of the tank into the interior of the mixing mechanism. The water is mixed with disinfectant inside the mixing mechanism and then sprayed out again. Inside the water tank, the water is disinfected to inhibit microorganisms and prevent water quality deterioration. When water moves within the mixing mechanism, it drives the second gear to rotate, which in turn drives the first gear. The diameter of the second gear is smaller than that of the first gear, making it easier for the second gear to drive the first gear. This causes the first gear to continuously rotate the crank-connecting rod. The bottom end of the crank-connecting rod is connected to one of the insulation plastic panels, which in turn causes the insulation plastic panels to move up and down continuously. The insulation plastic panels are rotatably connected to each other via a rotating shaft. The continuous up-and-down movement of the insulating plastic panels causes other insulating plastic panels to move up and down as well, resulting in simple harmonic motion of the insulating plastic panels on the water surface. This motion increases the amplitude of water movement within the pool, facilitating the even mixing of disinfectant into the water. Furthermore, the constant agitation of the water with the insulating plastic panels moves impurities settled at the bottom of the pool upwards, making it easier for the suction tube to draw these impurities into the collection tank. This also prevents impurities from clogging the fire-fighting mechanism during fire suppression. When the water temperature inside the pool is low and about to freeze, the insulating plastic panels placed on the water surface insulate the water and reduce the risk of freezing. The probability of ice formation on a small water surface is reduced; the second water pump draws water from the pool into the heating mechanism. The heated water then passes through the mixing mechanism to the water surface, increasing its temperature. Simultaneously, the insulating plastic plate undergoes simple harmonic motion on the water surface, continuously compressing the water. The water flows through grooves on the surface of the insulating plastic plate, which is fitted with magnets at both ends. The water flowing through these grooves is magnetized, making it less prone to freezing. As the water flows between the magnets, the polar water molecules cut the magnetic lines of force and tend to align themselves under the influence of the magnetic field. After exiting the magnetizer, the water molecules cannot quickly return to their original chaotic state of motion, further reducing the likelihood of freezing. The continuous impact and compression of the water surface by the insulating plastic plate, causing it to undergo simple harmonic motion, increases its fluidity and reduces the probability of freezing.

Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] Please refer to the following: Figures 1 to 11The tunnel high-level fire water tank control system includes: a tunnel 1; a water tank 2, which is constructed in the soil above the tunnel 1; a first water inlet mechanism 4, which is fixed to the top of the water tank 2; an overflow mechanism 5, which is installed on the side wall of the water tank 2; and a second water inlet mechanism 8, which includes a collection tank 81, a cylinder 82, a filter screen 83, a through hole 84, a fixed pipe 85, a second connecting pipe 86, a suction pipe 87, a second water pump 88, and a gauze layer 89. The collection tank 81 and the filter screen 82 are installed at the bottom of the water tank 2. The cylindrical body 82 has filter screens 83 installed on its side walls, along with the collection pool 81. A gauze layer 89 is fitted over the side walls of the filter screens 83. A through hole 84 is provided at the connection between the collection pool 81 and the cylindrical body 82, located inside the filter screen 83. A second water pump 88 is installed inside the cylindrical body 82, connected to a suction pipe 87, which is also connected to the filter screen 83 located inside the collection pool 81. The filter screen 83 located on the side wall of the cylindrical body 82 is connected to a fixing pipe 85. The second connecting pipe 86 is installed obliquely on the side wall of the fixed pipe 85; a heating mechanism 7 is installed on the side wall of the cylinder 82; a fire-fighting mechanism 6 connects the heating mechanism 7 and the cylinder 82; a mixing mechanism 9 is fixed to the top of the water tank 2 and is connected to the heating mechanism 7; a heat preservation mechanism 3 includes a heat preservation plastic plate 31, a crank connecting rod 32, a shell 33, a first gear 34, a second gear 35, a groove 36, a magnet 37, and a rotating shaft 38. The outer casing 33 is installed at one end of the coupling mechanism 9. The first gear 34 and the second gear 35 are rotatably connected inside the outer casing 33, and the first gear 34 meshes with the second gear 35. The crank connecting rod 32 is installed at one end of the first gear 34, and the crank connecting rod 32 is rotatably connected to one of the thermal insulation plastic plates 31. Adjacent thermal insulation plastic plates 31 are rotatably connected by the rotating shaft 38. The side wall of the thermal insulation plastic plate 31 is provided with multiple grooves 36, and the magnets 37 are symmetrically installed inside the thermal insulation plastic plate 31.
[0031] The heating mechanism 7 includes a housing 71, a heating tube 72, a heating coil 73, a first connecting pipe 74, and protrusions 75. The housing 71 is installed on one side of the cylindrical body 82. The heating tubes 72 are installed inside the housing 71 in an "S" shape. The heating coil 73 is wound around the side wall of the heating tubes 72 inside the housing 71, and multiple protrusions 75 are installed inside this part of the heating tubes 72. The side wall of the first connecting pipe 74 is connected to the second water pump 88, the second connecting pipe 86, and the heating tubes 72. In order to facilitate water to enter the interior of the heating tubes 72 through the first connecting pipe 74, the water comes into contact with the protrusions 75 during its movement inside the heating tubes 72. The protrusions 75 disturb the water flow, increase the heat exchange efficiency, and facilitate the heat emitted by the heating coil 73 to enter the water, thereby increasing the water temperature.
[0032] The fire-fighting mechanism 6 includes a fire-fighting pipe 61, a drain pipe 62, a solenoid valve 63, and a compression pipe 64. The fire-fighting pipe 61 is installed at the top of the tunnel 1. The two ends of the drain pipe 62 are connected to the fire-fighting pipe 61 and the cylinder 82, respectively. The compression pipe 64 is installed at an angle on the side wall of the first connecting pipe 74. The compression pipe 64 points to the top of the drain pipe 62, and the connection between the drain pipe 62 and the cylinder 82 is located inside the housing 71. In order to facilitate the heating coil 73 to heat the top of the drain pipe 62 and prevent the top of the drain pipe 62 from freezing, it is convenient for water inside the cylinder 82 to pass through the drain pipe 62 and enter the interior of the fire-fighting pipe 61 for fire extinguishing.
[0033] The mixing mechanism 9 includes a storage tank 91, a feeding pipe 92, a fixed shaft 93, fan blades 94, a mounting pipe 95, a pull rod 96, a bracket 97, a sealing block 98, and a piston 99. The storage tank 91 is installed inside the top of the water tank 2. The two ends of the feeding pipe 92 are respectively connected to the storage tank 91 and the outer shell 33. The sealing block 98 and the bracket 97 are installed inside the feeding pipe 92. The pull rod 96 is slidably connected to the inside of the bracket 97. The piston 99 is installed at the top of the pull rod 96, and the piston 99 engages with the funnel-shaped sealing block 98. The fixed shaft 93 and the fan blades 94 are rotatably connected inside the outer shell 33, and the mounting pipe 95 and the heating pipe 72 are symmetrically connected to the side wall of the outer shell 33. Multiple fan blades 94 are installed on the side wall of the fixed shaft 93. The fan blade 94 is slidably connected to the pull rod 96, which has a spherical end. When water quickly enters the interior of the outer casing 33 through the heating pipe 72, the water drives the fan blade 94 and the fixed shaft 93 to rotate. During rotation, the fan blade 94 presses against the spherical pull rod 96, causing it to move upwards along the bracket 97. The pull rod 96 pushes the piston 99 to disengage from the sealing block 98, allowing the disinfectant inside the discharge pipe 92 to pass through and enter the interior of the outer casing 33. The disinfectant mixes with the water and enters the water tank 2. When the fan blade 94 separates from the pull rod 96, under gravity, the pull rod 96 drives the piston 99 to engage the sealing block 98, sealing the discharge pipe 92. This allows the disinfectant to slowly enter the water, preventing excessive disinfectant in the water.
[0034] The solenoid valve 63 is installed on the side wall of the drain pipe 62, the compression pipe 64, the first connecting pipe 74, the fixing pipe 85, the second connecting pipe 86 and the discharge pipe 92 respectively, so as to facilitate the opening and closing of the drain pipe 62, the compression pipe 64, the first connecting pipe 74, the fixing pipe 85, the second connecting pipe 86 and the discharge pipe 92.
[0035] The first water inlet mechanism 4 includes an inlet pipe 41, a first water pump 42, a connector 43, a fixing plug 44, a rotating rod 45, a fulcrum 46, a lever 47, a float 48, and a connecting pipe 49. The two ends of the inlet pipe 41 are respectively connected to the connector 43 and the first water pump 42. The connector 43 is fixed inside the water tank 2, and the connecting pipe 49 is installed on the side wall of the connector 43. The fixing plug 44 is slidably connected inside the connector 43. The two ends of the rotating rod 45 are rotatably connected to the fixing plug 44 and the lever 47, respectively. The lever 47 is connected to the connector 43 via the fulcrum 46. The lever 47, which is rotatably connected and has a "V"-shaped sidewall, is fixedly connected to the float 48. In order to replenish the interior of the water tank 2 by the first water pump 42 through the water inlet pipe 41, as the liquid level inside the water tank 2 rises, it pushes the float 48 to move upward. The float 48 pushes the lever 47 to rotate. The lever 47 pushes the rotating rod 45 and the fixed plug 44 to move, so that the fixed plug 44 gradually moves closer to the connector 43. When the liquid level inside the water tank 2 is appropriate, the fixed plug 44 closes the connector 43 to prevent the liquid level inside the water tank 2 from being too high.
[0036] The overflow mechanism 5 includes an overflow pipe 51, a retaining ball 52, a spring 53, a fixing block 54, and a crossbar 55. The overflow pipe 51, with an "L"-shaped sidewall, is installed at the top of the water tank 2. The crossbar 55 and the fixing block 54 are installed inside the overflow pipe 51. The fixing block 54, with an internal funnel shape, engages the retaining ball 52. The two ends of the spring 53 are respectively fixedly connected to the retaining ball 52 and the crossbar 55. When the liquid level inside the water tank 2 exceeds the overflow pipe 51... When water enters the overflow pipe 51 and comes into contact with the retaining ball 52, under the pressure of the water, the retaining ball 52 moves downward, disengages from the fixing block 54, and compresses the spring 53, so that excess water inside the water tank 2 can flow out through the overflow pipe 51. After the excess water inside the water tank 2 is drained, the spring 53 extends and pushes the retaining ball 52 to close the fixing block 54, preventing debris from entering the water tank 2 through the overflow pipe 51 and maintaining the water quality inside the water tank 2.
[0037] The top of the water tank 2 is provided with an inspection port 21 and a vent pipe 22. One end of the vent pipe 22 is curved and the opening faces downward. In order to allow air to enter the interior of the water tank 1 through the curved vent pipe 22, the curved vent pipe 22 prevents impurities from entering the interior of the water tank 2.
[0038] The working principle of the tunnel high-level fire water tank control system provided by this invention is as follows: The device is connected to an external power supply. The liquid level sensor inside the water tank 2 monitors the water level inside the water tank 2. When the water level inside the water tank 2 is too low, the liquid level sensor transmits the information to the PLC control cabinet. The PLC control cabinet operates to turn on the first water pump 42. The first water pump 42 operates to replenish water into the water tank 2 through the water inlet pipe 41. As the liquid level inside the water tank 2 rises, it pushes the float 48 upward. The float 48 pushes the lever 47 to rotate. The lever 47 pushes the rotating rod 45 and the fixed plug 44 to move, causing the fixed plug 44 to gradually approach the connector 43. When the liquid level inside the water tank 2 is appropriate, the fixed plug 44 closes the connector 43, preventing the liquid level inside the water tank 2 from becoming too high. During the high temperatures of summer and autumn, the second water pump 88 is turned on once a month, simultaneously opening the solenoid valve 63 on the side wall of the first connecting pipe 74 and the discharge pipe 92. The operation of the second water pump 88 generates suction inside the suction pipe 87, causing water from the bottom of the water tank 2 to pass through the gauze layer 89 and the filter screen 83 and enter the interior of the suction pipe 87. Sediment at the bottom of the water tank 2 moves towards the collection tank 81, facilitating its deposition. The second water pump 88 then rapidly pumps water from the bottom of the water tank 2 through the heating pipe 72 into the interior of the outer casing 33. This water drives the fan blades 94 and the fixed shaft 93 to rotate. During the rotation of the fan blade 94, the bottom of the spherical pull rod 96 is squeezed, causing the pull rod 96 to move upward along the bracket 97. The pull rod 96 pushes the piston 99 to disengage from the sealing block 98, allowing the disinfectant inside the feed pipe 92 to pass through the feed pipe 92 and enter the interior of the outer shell 33. After the disinfectant mixes with water, it enters the water tank 2 through the installation pipe 95 to disinfect the water inside the water tank 2, inhibit microorganisms in the water, and prevent water quality deterioration. When the fan blade 94 separates from the pull rod 96, under the action of gravity, the pull rod 96 drives the piston 99 to engage the sealing block 98, sealing the feed pipe 92, thereby allowing the disinfectant to slowly enter the water and preventing excessive disinfectant in the water.When the fixed shaft 93 moves, it drives the second gear 35 to rotate. The second gear 35 drives the first gear 34 to rotate. The diameter of the second gear 35 is smaller than the diameter of the first gear 34. The second gear 35 drives the first gear 34 to rotate with less effort, thereby causing the first gear 34 to drive the crank connecting rod 32 to rotate continuously. The bottom end of the crank connecting rod 32 is connected to one of the heat-insulating plastic plates 31. The crank connecting rod 32 drives the heat-insulating plastic plates 31 to move up and down continuously. The heat-insulating plastic plates 32 are rotatably connected to each other through the rotating shaft 38. When the heat-insulating plastic plates 32 move up and down continuously, they drive the other heat-insulating plastic plates 32 to move up and down continuously, thereby causing the heat-insulating plastic plates 32 to perform simple harmonic motion on the water surface (as shown in the appendix). Figure 6 As shown in the diagram, the insulating plastic plate 32 causes the water to undergo simple harmonic motion, increasing the water's movement amplitude within the water tank 2. This facilitates the even mixing of disinfectant into the water. Furthermore, the continuous agitation of the water within the tank, caused by the insulating plastic plate 2, moves impurities settled at the bottom upwards, allowing the suction pipe 87 to draw these impurities into the collection tank 81. In winter, when the temperature sensor inside the water tank 1 detects that the water temperature is below 3°C, the PLC control cabinet activates the second water pump 88, the heating coil 73, and the solenoid valve 63 on the side wall of the first connecting pipe 74. Water enters the heating pipe 72 through the first connecting pipe 74. During its movement within the heating pipe 72, the water contacts the protrusion 75, which agitates the water flow, increasing heat exchange efficiency and allowing the heat emitted by the heating coil 73 to enter the water, raising its temperature. The heated water then enters the top of the water tank 2, further increasing the water temperature. The insulating plastic board 31 is laid on the water surface to insulate the water and reduce the chance of freezing. Simultaneously, the insulating plastic board 31 undergoes simple harmonic motion on the water surface, continuously compressing the water. The water flows through the grooves 36 on the surface of the insulating plastic board 31. Magnets 37 are installed at both ends of the insulating plastic board 31. The water flowing through the grooves 36 is magnetized by the magnets 37. Magnetized water is even less likely to freeze. As the water flows between the two magnets 37 (as shown in the attached diagram)... Figure 7As shown), polar water molecules cut magnetic field lines and, under the influence of the magnetic field, tend to align in a specific direction. After flowing out of the magnetizer, the water molecules cannot quickly return to their original chaotic state of motion, thus making them less prone to freezing. The insulation plastic plate continuously impacts and compresses the water surface, causing the water surface to undergo simple harmonic motion with the insulation plastic plate 31, increasing its fluidity and reducing the probability of freezing. When a fire occurs inside the tunnel 1, the smoke alarm inside the tunnel 1 is triggered, and the PLC control cabinet operates to open the second water pump 88, the solenoid valve 63 on the side wall of the exhaust pipe 62, and the solenoid valve 63 on the side wall of the second connecting pipe 86. Water from the pool 2 passes through the through hole 84 into the interior of the cylinder 82 and the drain pipe 62, and the second water pump 88 pumps water through the second connecting pipe 86 into the filter screen 83 on the surface of the cylinder 82. Due to the lack of cleaning over a long period of time, the filter screen 83 on the surface of the cylinder 82... Dust adheres to the surfaces of filter screen 83 and gauze layer 89. At this time, the second water pump 88 pumps water to backwash filter screen 83 and gauze layer 89 for 15 seconds. The PLC control cabinet then shuts off the second water pump 88 and opens the solenoid valve 63 on the side wall of the fixed pipe 85, allowing water from the water tank 2 to quickly pass through the gauze layer 89, filter screen 83, and fixed pipe 85 into the drain pipe 62. The water then flows through the drain pipe 62 into the fire extinguishing pipeline 61 to extinguish the fire in tunnel 1. A pressure sensor is installed inside the drain pipe 62 to detect the water pressure. As the water level in the tank decreases, the water pressure inside the drain pipe 62 decreases. The PLC control cabinet then turns on the second water pump 88 and opens the solenoid valve 63 on the side wall of the compression pipe 64. The second water pump 88 pumps water through the compression pipe 64 and quickly and obliquely flushes it into the drain pipe 62, replenishing the water pressure inside the drain pipe 62 and accelerating the fire extinguishing efficiency.
