Description
Technical Field
[0001] This application relates to the field of fire protection systems, and particularly to an automatic sprinkler system. Background Art
[0002] Currently, the fire safety measures in buildings mainly include manual fire extinguishers, fire hydrants, and smoke alarms, etc. Among them, both manual fire extinguishers and fire hydrants have the problem that they require professional operation. The smoke alarm triggers an alarm by detecting the smoke concentration to remind people to evacuate, but it cannot directly carry out fire extinguishing treatment.
[0003] Although these traditional devices can reduce the losses caused by fires to a certain extent, they have obvious deficiencies in terms of rapid response and automation, resulting in the inability to quickly extinguish fires. Summary of the Invention
[0004] In order to quickly extinguish fires, this application provides an automatic sprinkler system.
[0005] This application provides an automatic sprinkler system adopting the following technical solutions: An automatic sprinkler system is installed in a house, including a plurality of sprinkler heads, a smoke sensor, and a temperature sensor installed in the house, and further includes a controller and a water tank installed on the roof. A water outlet pipe is fixedly connected to the water tank, and a water outlet pump and a solenoid valve are installed on the water outlet pipe. Both the water outlet pump and the solenoid valve are electrically connected to the controller, and each sprinkler head is communicated with the water outlet pipe through a pipeline; A water inlet pipe is also fixedly connected to the water tank, the water inlet pipe is connected to a water source, a water inlet pump is installed on the water inlet pipe, and a water level sensor for detecting the water level is installed in the water tank. Both the water level sensor and the water inlet pump are electrically connected to the controller.
[0006] By adopting the above technical solutions, in the normal state, the smoke sensor and the temperature sensor monitor the environment in the house in real time, and the water level sensor detects the water level in the water tank. When the water level in the water tank is lower than the set water level, the water level sensor transmits a signal to the controller, and the controller sends an alarm through the network. The operator manually starts the water inlet pump through the controller to inject water into the water tank. When the water level rises to the predetermined water level, the water level sensor transmits a signal to the controller, and the controller controls the water inlet pump to stop working; when a fire occurs, the temperature sensor and the smoke sensor transmit signals to the controller, and the controller controls the water outlet pump and the solenoid valve to work, so that water enters the sprinkler heads and is sprayed into the house by the sprinkler heads, thereby extinguishing the fire. At the same time, the controller also sends an alarm to remind professional personnel to intervene in fire extinguishing. During fire extinguishing, the dependence on manual intervention is reduced, the fire response speed is improved, and the fire can be detected and extinguished faster.
[0007] Optionally, a collection component for collecting water is further provided in the water tank.
[0008] By adopting the above technical solution, rainwater can be collected for use, achieving the purpose of saving water.
[0009] Optionally, a through hole is provided at the top of the water tank. The collection assembly includes a cover body hinged to the top of the water tank for closing the through hole, and a support member for supporting the cover body and controlling the rotation of the cover body is further provided in the water tank; A filtering device is slidably connected to the inner wall of the water tank and is located below the cover body. The sliding direction of the filtering device is arranged along the height direction of the water tank. The filtering device is located on the side away from the hinge axis of the cover body and is close to the water outlet pipe. A support spring is connected to the housing of the filtering device, and the lower end of the support spring is fixed in the water tank to support the filtering device; A filter plate is hinged to one side of the lower surface of the housing of the filtering device close to the water outlet pipe. The side of the filter plate away from the housing of the filtering device is slidably connected to the inner bottom wall of the water tank, and the filter plate slides along the length direction of the water tank.
[0010] By adopting the above technical solution, the support member supports the cover body to be horizontal, so that the cover body closes the top opening of the water tank, reducing the occurrence of the situation that external sundries enter the water tank and pollute the water; when it rains, the controller controls the support member to work, so that the cover body rotates downward, thereby opening the through hole of the water tank, and the rainwater can enter the water tank. The filtering device filters the rainwater entering the water tank for the first time; as the cover body continues to rotate, the cover body contacts the filtering device and presses the filtering device to move downward, while compressing the support spring. The filtering device presses the filter plate to rotate. Since the filtering device moves downward, the filtering device makes room for the rotation of the cover body, so that the cover body can rotate as low as possible, thereby making the through hole of the water tank open larger and more rainwater can enter the water tank.
[0011] The water level sensor detects the water level. When the water level rises to a predetermined water level, the controller controls the support member to work, so that the cover body rotates upward to close the through hole of the water tank, thereby preventing rainwater from continuing to enter the water tank. At the same time, the support spring restores its deformation and drives the filtering device and the filter plate to reset; when it stops raining and the water level does not rise to the predetermined water level, the operator controls the support member to work through the controller, so that the cover body rotates upward to close the through hole of the water tank, reducing the entry of external sundries into the water tank.
[0012] When a fire occurs and the water in the water tank is used, the filter plate filters the water entering the water outlet pipe for the second time in a refined manner, reducing the occurrence of the situation that impurities in the water damage the water outlet pump, the solenoid valve and the sprinkler head.
[0013] Optionally, the support member includes two support rails slidably connected to the inner wall of the long side of the water tank. The length directions of the two support rails are arranged along the length direction of the water tank, and the sliding direction of the support rails is arranged along the height direction of the water tank. Hydraulic cylinders are provided at both ends of the support rails and below them. The telescopic direction of the hydraulic cylinders is consistent with the height direction of the water tank. The telescopic ends of the hydraulic cylinders are fixed to the support rails, and the cylinder barrels of the hydraulic cylinders are fixed to the water tank. The hydraulic system of the hydraulic cylinders is electrically connected to the controller; On one side of the lower surface of the cover body away from its hinge axis, a mating block corresponding to each support rail is hinged. The cross section of the mating block is T-shaped, and each mating block is slidably inserted into the corresponding support rail, and the mating block cannot be separated from the support rail.
[0014] By adopting the above technical solution, the cooperation of the hydraulic cylinder, the support rail and the mating block makes the cover body horizontal to close the through hole of the water tank; when it is necessary to make the cover body rotate downward to open the through hole of the water tank, the controller controls the hydraulic system of the hydraulic cylinder to work, so that the hydraulic cylinder contracts, and the hydraulic cylinder drives the support rail and the mating block to move downward. The mating block drives the cover body to rotate downward, and at the same time the cover body makes the mating block move towards the direction close to the hinge axis of the cover body; when it is necessary to make the cover body rotate upward to close the through hole of the water tank, the controller controls the hydraulic system of the hydraulic cylinder to work, so that the hydraulic cylinder extends, and the hydraulic cylinder pushes the support rail and the mating block to move upward, so that the cover body rotates upward. At the same time, the cover body makes the mating block move away from the hinge axis of the cover body. When the hydraulic cylinder returns to the initial state, the cover body is horizontal, so as to close the through hole of the water tank.
[0015] Optionally, a cleaning assembly for cleaning the filter plate is further provided in the water tank.
[0016] By adopting the above technical solution, the cleaning assembly cleans the impurities on the filter plate, reducing the occurrence of filter plate blockage.
[0017] Optionally, the cleaning assembly includes an annular scraping plate slidably sleeved on the filter plate. Both ends of the scraping plate are connected with telescopic rods with adjustable lengths. The ends of the telescopic rods away from the scraping plate penetrate through the support rail and are fixed to the corresponding mating blocks. Strip-shaped holes for the telescopic rods to pass through and slide are formed on the support rail.
[0018] By adopting the above technical solution, when the cover body is horizontal, the scraping plate is located on the higher side of the filter plate. When the cover body rotates downward, the cover body drives the mating block, the telescopic rod and the scraping plate to move towards the direction close to the hinge axis of the cover body, so that the scraping plate moves from the higher side of the filter plate to the lower side. When the scraping plate moves, it can scrape off the impurities covering the surface of the filter plate, achieving the effect of cleaning the filter plate; when the cover body rotates upward, the cover body drives the mating block, the telescopic rod and the scraping plate to move away from the hinge axis of the cover body, so that the scraping plate moves from the lower side of the filter plate to the higher side. When the cover body rotates to the horizontal position, the scraping plate and the telescopic rod move to the initial position.
[0019] Optionally, a control component for controlling the opening and closing of the cover body is further provided on the water tank.
[0020] By adopting the above technical solution, the control component can automatically replenish water for the automatic sprinkler fire extinguishing system, reducing manual intervention.
[0021] Optionally, the control component includes an installation groove formed by recessing downward from the top surface of the water tank. A support plate is provided in the installation groove. The support plate is slidably connected to the groove wall of the installation groove, and the sliding direction of the support plate is set along the height direction of the water tank. A limiting spring for supporting the support plate is connected to the support plate, and the lower end of the limiting spring is fixed to the groove wall of the installation groove; A sponge is fixedly connected to the upper surface of the support plate, and a distance measuring sensor is installed on the lower surface of the support plate. The distance measuring sensor is used to measure the distance between the lower surface of the support plate and the bottom wall of the installation groove, and the distance measuring sensor is electrically connected to the controller.
[0022] By adopting the above technical solution, when it is not finished raining, the limiting spring supports the support plate and the sponge. At this time, the bottom groove wall of the installation groove is outside the detection range of the distance measuring sensor. When the water level sensor detects that the water level is lower than the set water level, during the rain, the sponge absorbs the rainwater, causing the weight of the sponge to gradually increase, so that the support plate can be pressed to move downward, and at the same time, the limiting spring is compressed. When the bottom wall of the installation groove does not enter the detection range of the distance measuring sensor, the cover body still closes the through hole of the water tank, and the rainwater flushes the top surface of the water tank and the surface of the cover body, thereby washing off the sundries on the water tank and the cover body, reducing the situation that sundries enter the water tank along with the rainwater when the cover body is opened.
[0023] When the bottom wall of the installation groove enters the detection range of the distance measuring sensor, the distance measuring sensor transmits a signal to the controller, and the controller controls the hydraulic cylinder to work, causing the cover body to rotate downward; when the rain stops, the operator can manually control the cover body to rotate and close through the controller, or wait for the water in the sponge to evaporate. As the water in the sponge gradually evaporates, the weight of the sponge also gradually decreases. At the same time, the limiting spring resumes its deformation and pushes the support plate and the sponge to move upward. When the bottom groove wall of the installation groove is outside the detection range of the distance measuring sensor, the distance measuring sensor transmits a signal to the controller, and the controller controls the hydraulic cylinder to work, causing the cover body to rotate upward and reset.
[0024] In summary, the present application includes at least one of the following beneficial technical effects: By setting a temperature sensor, a smoke sensor, a water outlet pipe, a water outlet pump, a solenoid valve, a sprinkler head, a water tank, a water inlet pipe, a water inlet pump, and a controller, the dependence on manual intervention during fire extinguishing is reduced, the fire response speed is improved, and the fire can be detected and extinguished faster; By setting up a cover body, a support member, a filtering device, a support spring, and a filter plate, rainwater can be collected and utilized, achieving the purpose of saving water. By setting up an installation groove, a support plate, a sponge, a limit spring, and a distance measuring sensor, the automatic sprinkler fire extinguishing system can be automatically replenished with water, reducing manual intervention.

Detailed Embodiments
[0034] The following is combined with the attached Figure 1-8A further detailed description of the present application is provided.
[0035] An embodiment of the present application discloses an automatic sprinkler system. Referring to Figure 1 And Figure 2 , it is installed on the house 1, including a water tank 2 installed outside the house 1, and a plurality of sprinkler heads 3, a temperature sensor 4, and a smoke sensor 5 installed on the inner top surface of the house 1. It also includes a controller 6. The position of the controller 6 in the figure is for convenient display. In fact, the position of the controller 6 can be selected according to the actual situation; a water outlet pipe 21 is fixedly connected to the water tank 2, and a water outlet pump 22 and a solenoid valve 23 are installed on the water outlet pipe 21. Each sprinkler head 3 is fixedly connected to the water outlet pipe 21 through a pipeline. By controlling the water outlet pump 22 and the solenoid valve 23, the water in the water tank 2 can be controlled to flow into the sprinkler head 3 through the pipeline. The water outlet pump 22, the solenoid valve 23, the temperature sensor 4, and the smoke sensor 5 are all electrically connected to the controller 6.
[0036] A water replenishing mechanism is also provided in the water tank 2. The water replenishing mechanism includes a water level sensor 24 installed inside the water tank 2. The water level sensor 24 is used to monitor the water level in the water tank 2, and the water level sensor 24 is electrically connected to the controller 6; the water replenishing mechanism also includes a water inlet pipe 25 fixedly connected to the water tank 2. The water inlet pipe 25 is connected to a water source, and a water inlet pump 26 is also installed on the water inlet pipe 25, and the water inlet pump 26 is electrically connected to the controller 6.
[0037] When there is no fire, the water level sensor 24 monitors the water level in the water tank 2. When the water level is lower than the set water level, the water level sensor 24 transmits a signal to the controller 6. The controller 6 sends an alarm message through the network to remind the operator to perform a water replenishing operation. When performing the water replenishing operation, the operator controls the water inlet pump 26 to work through the controller 6, so as to pump the water from the water source into the water tank 2 through the water inlet pipe 25, thereby being able to replenish water. When the water level rises to the set value, the water level sensor 24 transmits a signal to the controller 6, and the controller 6 controls the water inlet pump 26 to stop working; thus ensuring that there is enough water stored in the water tank 2.
[0038] The smoke sensor 5 and the temperature sensor 4 monitor the smoke and temperature in the house 1, and can monitor the environmental changes in the house 1 in real time. When a fire occurs, the temperature sensor 4 and the smoke sensor 5 simultaneously detect abnormal signals and transmit the data to the controller 6. At this time, the controller 6 controls the water outlet pump 22 and the solenoid valve 23 to work, so as to pump the water in the water tank 2 into the sprinkler head 3, and the sprinkler head 3 sprays the water into the house 1, thereby extinguishing the fire. At the same time, the controller 6 can send an alarm message through the network to notify relevant personnel to take further actions; reducing the dependence on manual intervention, improving the fire response speed, and being able to detect and extinguish fires faster.
[0039] Referring to Figure 2 AndFigure 3 The water replenishment mechanism also includes a collecting component 7 for collecting rainwater. A through hole connected to the water tank 2 is opened on the top surface of the water tank 2. The collecting component 7 includes a cover body 71 for blocking the through hole. The cover body 71 is hinged on the top surface of the water tank 2, and the axis of the hinge shaft of the cover body 71 is arranged along the width direction of the water tank 2; the collecting component 7 also includes a support member 72 for supporting the cover body 71 and controlling the rotation of the cover body 71.
[0040] Reference Figure 3 , Figure 4 and Figure 5 The support member 72 includes two support rails 721 located below the cover body 71, the length direction of the support rails 721 is arranged along the length direction of the water tank 2, and the two support rails 721 are respectively slidably connected to the inner walls of the two long sides of the water tank 2, and the sliding direction of the support rails 721 is arranged along the height direction of the water tank 2; both ends of the side walls of the two support rails 721 that are away from each other are fixedly connected with sliders 722, and the inner wall of the water tank 2 is provided with slide grooves 27 corresponding to the sliders 722 one by one, and the length direction of the slide grooves 27 is arranged along the height direction of the water tank 2, and each slider 722 is slidably inserted in the corresponding slide groove 27.
[0041] A hydraulic cylinder 723 is provided below both ends of the support rail 721. The telescopic direction of the hydraulic cylinder 723 is consistent with the height direction of the water tank 2. The telescopic end of the hydraulic cylinder 723 is connected and fixed to the corresponding support rail 721. The cylinder barrel of the hydraulic cylinder 723 is fixedly connected to the inner wall of the water tank 2. The hydraulic system of the hydraulic cylinder 723 is electrically connected to the controller 6; the side of the lower surface of the cover body 71 away from its own hinge axis is hinged with a matching block 724 corresponding to the support rail 721 one by one, and the cross-section of the matching block 724 is T-shaped. Each matching block 724 is slidably inserted in the corresponding support rail 721. Since the cross-section of the matching block 724 is T-shaped, the matching block 724 cannot be separated from the support rail 721.
[0042] Reference Figure 2 and Figure 6 The collecting assembly 7 also includes a filtering device 73 located in the water tank 2. The filtering device 73 is slidably connected to one of the short side walls of the water tank 2, and the filtering device 73 is located on a side away from the hinge axis of the cover body 71. The water outlet pipe 21 and the filtering device 73 are located on the same side of the water tank 2. The filtering device 73 includes a shell and filtering particles filled in the shell. A limiting plate 731 is fixedly connected to the upper surface of the shell of the filtering device 73. The length direction of the limiting plate 731 is set along the width direction of the water tank 2, and the limiting plate 731 is located on a side of the filtering device 73 close to the hinge axis of the cover body 71.
[0043] A connecting block 732 is fixedly connected to the housing of the filtering device 73. In this embodiment, the number of the connecting blocks 732 is two. The connecting blocks 732 are located on one side of the filtering device 73 away from the hinge axis of the cover body 71. Connecting grooves 28 corresponding to the connecting blocks 732 one by one are formed in the inner wall of the water tank 2. The length direction of the connecting grooves 28 is arranged along the height direction of the water tank 2. Each connecting block 732 is slidably inserted into the corresponding connecting groove 28. A supporting spring 74 is fixedly connected to the lower surface of the connecting block 732. The lower end of the supporting spring 74 is fixedly connected to the inner bottom wall of the water tank 2. The supporting spring 74 supports the connecting block 732 and the filtering device 73.
[0044] Refer to Figure 2 , Figure 6 and Figure 7 , a filter plate 75 is hinged to the lower surface of the housing of the filtering device 73. The hinge axis of the filter plate 75 is located on one side of the filtering device 73 away from the hinge axis of the cover body 71. The length direction of the filter plate 75 is arranged along the width direction of the water tank 2. And the inner walls of the two long sides of the water tank 2 are close to the corresponding side walls of the filter plate 75. One side of the filter plate 75 away from the filtering device 73 faces downward and is inclined toward the direction close to the hinge axis of the cover body 71. A T-shaped sliding block 751 is hinged to one side of the filter plate 75 close to the hinge axis of the cover body 71. Sliding grooves 29 corresponding to the sliding blocks 751 one by one are formed in the inner bottom wall of the water tank 2. The length direction of the sliding grooves 29 is arranged along the length direction of the water tank 2. Each sliding block 751 is slidably inserted into the corresponding sliding groove 29. The filter plate 75 blocks the inlet end of the water outlet pipe 21, so that the water entering the water outlet pipe 21 can be finely filtered for the second time, reducing the occurrence of the situation that impurities damage the water outlet pump 22, the solenoid valve 23 and the nozzle 3.
[0045] Refer to Figure 2 and Figure 8 , a control assembly 8 for controlling the rotation of the cover body 71 is further provided on the water tank 2. An installation groove 81 is formed by the downward depression of the upper surface of the water tank 2. The installation groove 81 is located on one side of the cover body 71. The control assembly 8 includes a support plate 82 located in the installation groove 81. Each side wall of the support plate 82 contacts the corresponding groove wall of the installation groove 81. At least two convex blocks 83 are fixedly connected to the side wall of the support plate 82. Grooves 84 corresponding to the convex blocks 83 one by one are formed in the groove wall of the installation groove 81. The length direction of the grooves 84 is arranged along the height direction of the water tank 2. Each convex block 83 is slidably inserted into the corresponding groove 84.
[0046] The lower surface of the bump 83 is fixedly connected with a limiting spring 85. The lower end of the limiting spring 85 is fixed to the lower end wall of the groove 84. The limiting spring 85 supports the bump 83 and the support plate 82. The upper surface of the support plate 82 is fixedly connected with a sponge 86. A ranging sensor 87 is installed on the lower surface of the support plate 82. The ranging sensor 87 is used to measure the distance between the lower surface of the support plate 82 and the bottom wall of the installation groove 81. The controller 6 is electrically connected to the ranging sensor 87.
[0047] When it does not rain, the limiting spring 85 supports the support plate 82 and the sponge 86. At this time, the bottom wall of the installation groove 81 is outside the detection range of the ranging sensor 87. The controller 6 controls the hydraulic system of the hydraulic cylinder 723 to work, so that the hydraulic cylinder 723, the support rail 721 and the mating block 724 cooperate to support the cover body 71, making the cover body 71 horizontal. At this time, the cover body 71 blocks the through hole of the water tank 2, reducing the situation that foreign objects enter the water tank 2 from the outside and cause water pollution.
[0048] In the state where the water level is lower than the set water level, when it rains, the sponge 86 absorbs the rainwater. As the rainwater absorbed by the sponge 86 gradually increases, the weight of the sponge 86 gradually increases. Therefore, the sponge 86 and the support plate 82 move downward and compress the limiting spring 85. During this process, the ranging sensor 87 works, and the rainwater also washes the upper surfaces of the cover body 71 and the water tank 2, washing off the foreign objects on the upper surfaces of the cover body 71 and the water tank 2, reducing the situation of foreign objects entering the water tank 2. As the sponge 86 and the support plate 82 continue to move, when the bottom wall of the installation groove 81 enters the detection range of the ranging sensor 87, the ranging sensor 87 transmits a signal to the controller 6.
[0049] The controller 6 controls the hydraulic system of the hydraulic cylinder 723 to work, so that the telescopic end of the hydraulic cylinder 723 moves downward, thereby driving the support rail 721 and the mating block 724 to move downward. The downward movement of the mating block 724 drives the cover body 71 to rotate downward and tilt. At the same time, the cover body 71 drives the mating block 724 to move towards the hinge axis of the cover body 71. The rotation of the cover body 71 opens the through hole of the water tank 2. At this time, the external rainwater can fall into the water tank 2 along the cover body 71 for collection. The cover body 71 guides the rainwater so that the rainwater falls into the filtering device 73. The filtering device 73 filters the rainwater, reducing the situation of mixed impurities in the water.
[0050] As the supporting rail 721 continues to move downward, the rotation angle of the cover body 71 gradually increases, and the opening degree of the through hole of the water tank 2 also becomes larger, enabling rainwater to enter the water tank 2 more quickly. When the supporting rail 721 moves to contact the limiting plate 731, as the supporting rail 721 continues to move downward, the supporting rail 721 presses the limiting plate 731 and the filtering device 73 to move downward, and at the same time the supporting spring 74 is compressed. Since the filtering device 73 moves downward, it can make more space for the rotation of the supporting rail 721 and the cover body 71, so that the through hole of the water tank 2 can be opened as large as possible, and rainwater can enter the water tank 2 more quickly.
[0051] During the downward movement of the filtering device 73, the filtering device 73 presses the higher side of the filter plate 75 to move downward, causing the filter plate 75 to rotate, and the lower side of the filter plate 75 moves toward the direction of the hinge shaft of the cover body 71. During this process, the filter plate 75 always blocks the inlet end of the water outlet pipe 21, so that the water entering the water outlet pipe 21 can be filtered at any time, and when there is a sudden water use, the situation where the filter plate 75 fails to filter the water in time is reduced.
[0052] During the process of collecting rainwater, the water level sensor 24 monitors the water level. When the water level rises to the predetermined water level, the controller 6 controls the hydraulic system of the hydraulic cylinder 723 to work, so that the hydraulic cylinder 723 pushes the supporting rail 721 and the matching block 724 to move upward, and at the same time the matching block 724 pushes the cover body 71 to gradually rotate to the horizontal. During this process, the supporting spring 74 also restores its deformation and drives the filtering device 73 and the higher side of the filter plate 75 to move upward. When the hydraulic cylinder 723 returns to the initial state, the cover body 71, the filtering device 73 and the filter plate 75 all return to the initial position, and the cover body 71 continues to block the through hole of the water tank 2 to prevent rainwater from continuing to enter the water tank 2.
[0053] If the rain stops and the water level in the water tank 2 does not rise to the predetermined water level, as the water in the sponge 86 evaporates, the weight of the sponge 86 gradually decreases. At the same time, the limiting spring 85 restores its deformation and drives the supporting plate 82 and the sponge 86 to move upward. When the bottom wall of the installation groove 81 is outside the detection range of the distance measuring sensor 87, the distance measuring sensor 87 transmits a signal to the controller 6, and the controller 6 controls the hydraulic cylinder 723 system of the hydraulic cylinder 723 to work, so that the cover body 71 rotates and closes; or the operator can manually control the hydraulic cylinder 723 to work through the controller 6, so that the cover body 71 is reset to block the through hole of the water tank 2.
[0054] Since the filter plate 75 filters the water entering the water outlet pipe 21, sundries may cover the filter plate 75, thus blocking the filter plate 75. To improve the above problems, refer to Figure 2 、 Figure 4 And Figure 6, a cleaning assembly 9 for cleaning the filter plate 75 is further provided in the water tank 2; the cleaning assembly 9 includes an annular scraping plate 91 slidably sleeved on the filter plate 75, and telescopic rods 92 with adjustable lengths are fixedly connected to both ends of the scraping plate 91. A strip-shaped hole for the telescopic rods 92 to pass through and slide is formed on the lower surface of the supporting rail 721. The telescopic ends of the telescopic rods 92 are inserted into the strip-shaped holes, and the telescopic ends of the telescopic rods 92 are fixedly connected to the corresponding matching blocks 724.
[0055] When the cover body 71 closes the through hole of the water tank 2, the scraping plate 91 is located on the side of the filter plate 75 away from the hinge shaft of the cover body 71. When the cover body 71 rotates downward, the cover body 71 drives the matching block 724, the telescopic rod 92 and the scraping plate 91 to move toward the hinge shaft of the cover body 71, so that the scraping plate 91 moves from the higher side of the filter plate 75 to the lower side of the filter plate 75. The movement of the scraping plate 91 can scrape off the sundries covering the filter plate 75, reducing the occurrence of the situation that the filter plate 75 is blocked by sundries; when the cover body 71 rotates upward, the cover body 71 drives the telescopic rod 92 and the scraping plate 91 to move through the matching block 724, so that the scraping plate 91 moves from the lower side of the filter plate 75 to the higher side. When the cover body 71 rotates to the horizontal state, the scraping plate 91 moves to the initial position.
[0056] The implementation principle of an automatic sprinkler system according to an embodiment of the present application is as follows: In the normal state, the smoke sensor 5 and the temperature sensor 4 monitor the environment in the house 1, and the water level sensor 24 monitors the water level in the water tank 2. When the water level is lowered to the set water level, the controller 6 sends an alarm message through the network. The operator can start the water inlet pump 26 through the controller 6 to replenish water into the water tank 2. When the water level rises to the predetermined water level, the controller 6 controls the water inlet pump 26 to close; when it is raining and the water level is lower than the set water level, the sponge 86 absorbs rainwater and presses down the support plate 82. When the support plate 82 moves down to the predetermined position, the controller 6 controls the hydraulic system of the hydraulic cylinder 723 to work, so that the hydraulic cylinder 723 contracts, and at the same time the cover body 71 rotates downward, so that the water tank 2 is opened, rainwater enters the water tank 2, and the matching block 724 drives the scraping plate 91 to move, and the scraping plate 91 scrapes off the sundries on the filter plate 75.
[0057] When the water level rises to the predetermined water level, the controller 6 controls the hydraulic system of the hydraulic cylinder 723 to work, so that the hydraulic cylinder 723 resets, so that the cover body 71 and the scraping plate 91 reset; when the rain stops and the water level does not rise to the predetermined water level, the operator can manually reset the cover body 71 and the scraping plate 91 through the controller 6, or wait for the water in the sponge 86 to evaporate, and the limit spring 85 resumes deformation and pushes the support plate 82 and the sponge 86 to reset. When the bottom wall of the installation groove 81 is outside the detection range of the distance measuring sensor 87, the controller 6 controls the hydraulic system of the hydraulic cylinder 723 to work, so that the cover body 71 and the scraping plate 91 move and reset.
[0058] When a fire breaks out, the temperature sensor 4 and the smoke sensor 5 simultaneously detect abnormal signals, and the controller 6 controls the water pump 22 and the solenoid valve 23 to work, so as to pump the water in the water tank 2 into the sprinkler 3. The filter plate 75 filters the water entering the water outlet pipe 21 for the second time, and the sprinkler 3 sprays the water into the house 1 to extinguish the fire. At the same time, the controller 6 sends an alarm message to notify relevant personnel to take further actions.
[0059] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
