[0001] The present invention relates to the technical field of alarm devices, and in particular to an irrigation area environment monitoring and early warning system based on distributed optical fiber sensing. Background Art

[0002] Distributed fiber optic sensing technology is a new type of sensing technology that uses light waves as carriers and optical fibers as media to sense and transmit physical and chemical parameters such as sound waves, vibrations, temperature, and strain in the external environment, and to perform intelligent identification and processing. The distributed fiber optic vibration monitoring system is an important branch of distributed fiber optic sensing.

[0003] Irrigation areas refer to irrigation areas with reliable water sources and water diversion, transmission, and distribution channel systems and corresponding drainage ditches. They are the product of human economic activities and develop with the development of social economy. Irrigation areas usually have complete water transmission, distribution, irrigation, and drainage engineering systems. They can provide irrigation and drainage services according to the needs of crops and take into account water resources and environmental carrying capacity. Planting areas are usually set up near irrigation areas. For planting areas, fire and theft are prone to occur, and the above problems are not easy to avoid.

The first connecting end and the second connecting end are respectively installed at the same height position on the two hollow tubes on the top of the base plate, and a connecting line is electrically connected between the first connecting end and the second connecting end. An air detection component is installed on the top of the hollow tube, and the air detection component includes a dust box, a fan is installed on the front end surface of the dust box, a temperature sensor is installed on the inner top of the dust box, and an air outlet is opened at the bottom of the dust box, and the top of the base plate is covered with a cover frame after the hollow tube is rotated and folded.

[0006] Furthermore, a metal hose is installed at the bottom of the base plate corresponding to the bottom of the hollow tube and the position of the interface of the optical fiber embedded tube. The two ends of the metal hose are respectively fixedly connected to the hollow tube and the optical fiber embedded tube. Fixing bolts are inserted at both ends of the base plate. A socket is fixed at the bottom of the optical fiber embedded tube corresponding to the fixing bolt, and the fixing bolt can be threadedly inserted into the socket.

[0007] Furthermore, the driving assembly also includes a bidirectional electric push rod, a bidirectional electric push rod is fixed on the surface of the base plate between the two tooth plates, and a connecting frame is fixed to the extended end of the bidirectional electric push rod, and the two connecting frames are fixedly connected to the corresponding tooth plates.

[0008] Furthermore, a second rotating seat is fixed to the other side of the base plate located on the first rotating seat, and a telescopic plate is rotatably installed on the surface of the second rotating seat. An outer plate is fixed to the bottom of the telescopic plate facing the toothed plate, and the front end of the toothed plate is at a distance from the outer plate.

[0009] Furthermore, a locking bolt is threadedly inserted at the storage port of the telescopic plate, and the locking bolt is in compression contact with the extended end of the telescopic plate, and an insertion frame is fixed to the back of the first connecting end and the second connecting end, and the upper and lower ends of the insertion frame are hollow, and an insertion block is slidably inserted in the insertion frame, and the insertion block is fixedly connected to the extended end of the telescopic plate.

[0010] Furthermore, the anti-theft component also includes a slide cylinder, the first connecting end and the second connecting end are internally fixed with the slide cylinder, and the slide cylinder is slidably sleeved on the outer surface of the hollow tube.

[0011] Furthermore, a baffle is fixed on the top of the insertion frame, and the baffle blocks a portion of the area of ​​the hollow portion at the upper end of the insertion frame, and the top of the insertion block is in compression contact with the baffle.

[0012] Furthermore, a rubber band is fixed to the back side of the first connection end and the second connection end, and the other end of the rubber band is fixed to the surface of the bottom plate.

[0013] Furthermore, the air detection component also includes a filter plate, the filter plate is rotated inside the dust box, and a weighing element is fixedly installed on the bottom of the filter plate, the weighing element is in contact with the bottom of the filter plate, and a rotating drum is fixed on the side of the dust box facing the hollow tube, and the rotating drum is rotatably installed on the outer surface of the hollow tube through bearings and torsion springs.

[0014] Furthermore, vertical plates are fixed on the outer surfaces of the first connecting end and the second connecting end, and pillars are fixed on the tops of the vertical plates. Slots corresponding to the pillars are provided on the surface of the rotating drum, and the opening end of the slot of the rotating drum has the same rotation path as the hollow tube.

[0015] Beneficial effects of the present invention: 1. In the present invention, when the hollow tube is vertically arranged on the base plate, the plug post of the vertical plate is manually plugged into the slot of the rotating drum, which is a common plug-in structure. The opening of the slot is the same as the rotation path of the hollow tube, which means that when the plug post is inserted into the slot, the hollow tube does not rotate and fold, and the rotating drum is always limited by the plug post, and cannot keep the fan end facing the planting area by rotating its own torsion spring. At the same time, when the hollow tube is rotated and folded by the driving assembly, it will not be interfered by the rotating drum. After the plug post is separated from the slot, the rotating drum rotates the fan and the dust box in a direction parallel to the base plate through the action of the torsion spring, so as to facilitate the subsequent covering of all structures on the base plate by the cover frame.

[0016] 2. The present invention adjusts the height of the connecting line by manually adjusting the height of the telescopic plate. The length of the telescopic plate can be locked by a locking bolt, and then the plug-in block is inserted into the interior of the plug-in frame. At this time, the first connecting end and the second connecting end are pulled by the rubber band and tend to move downward, while the baffle plate on the top of the plug-in frame is in compression contact with the plug-in block, so that the first connecting end and the second connecting end cannot move downward and maintain the position height. At the same time, the baffle plate only contacts a part of the surface of the plug-in block and can be dislocated by extrusion of external force, which will neither interfere with the rotation of the hollow tube nor affect the maintenance of the height of the first connecting end and the second connecting end.

[0017] 3. When the hollow tube of the present invention rotates, the first connecting end and the second connecting end slide along the surface of the hollow tube due to the elastic traction of the rubber band. When the hollow tube is completely rotated to a horizontal state, the position of the connecting end can just meet the state that the connecting line is still taut, thereby preventing the loosening of the connecting line from affecting the covering of the cover frame on the bottom plate.

[0018] 4. The present invention uses a bidirectional electric push rod to push the connecting frame and the tooth plate to move. The two tooth plates are engaged with the gears to drive the hollow tube to rotate, so that the hollow tube can be monitored and warned of the environment in a vertical state, and the hollow tube can be folded. The length of the bottom plate can meet the requirements of the two hollow tubes being folded towards each other, so that the internal structure can be stored and protected after being covered on the bottom plate by a cover frame, which makes it convenient for people to enter the irrigation area for planting work.

[0019] 5. The hollow tube of the present invention is connected to the optical fiber buried tube through a metal hose. The hollow tube can rotate at an angle. By plugging the fixing bolts into the socket, the base plate and the optical fiber buried tube can be locked and connected, thereby realizing the corresponding installation of a section of optical fiber buried tube and a group of base plates. At the same time, the base plate can be fixed to the ground through fixing bolts to maintain the stability of the monitoring and early warning system.

[0020] 6. Compared with the prior art, the present invention arranges the anti-theft component and the air detection component through the two hollow tubes that are deployed by the driving component, and cooperates with the optical fiber buried tube to monitor the temperature and fire protection from underground and above ground respectively, and at the same time, provide anti-theft warnings in the enclosed area, which can improve the overall protection effect and enable faster response when problems occur.

The cover frame 22 is a common directional frame and can wrap the folded hollow tube 3. To achieve the effect of protection and storage, the optical fiber buried tube 1 in this article is the same as the existing distributed optical fiber sensing technology. The three-way connector 11 can achieve multi-angle connection, so that the monitoring area runs through the irrigation area, and the irrigation area can also be wrapped for anti-theft and environmental monitoring from the outside. When using the device, the optical fiber buried tube 1 is pre-buried underground, and the base plate 2 is installed on the ground. The hollow tube 3 on the base plate 2 is expanded to a vertical shape through the driving component 6, and the temperature and dust on the ground are monitored through the air detection component 5 and the anti-theft component 4, which plays a role in fire prevention and anti-theft protection.

[0025] In this embodiment, a metal hose 24 is installed at the position of the bottom of the bottom plate 2 corresponding to the interface between the hollow tube 3 and the optical fiber buried tube 1, and the two ends of the metal hose 24 are fixedly connected to the hollow tube 3 and the optical fiber buried tube 1 respectively. The two ends of the bottom plate 2 are inserted with fixing bolts 23, and the bottom of the optical fiber buried tube 1 corresponding to the fixing bolts 23 is fixed with a socket 12, and the fixing bolts 23 can be threadedly inserted into the socket 12. The hollow tube 3 is connected to the optical fiber buried tube 1 through the metal hose 24, and the hollow tube 3 can be rotated. The bottom plate 2 and the optical fiber buried tube 1 can be locked and connected by plugging the fixing bolts 23 into the socket 12, so as to realize the corresponding installation of a section of optical fiber buried tube 1 and a group of bottom plates 2. At the same time, the bottom plate 2 can be fixed to the ground by the fixing bolts 23 to maintain the stability of the monitoring and early warning system.

[0026] In this embodiment, the driving assembly 6 also includes a bidirectional electric push rod 61, the bidirectional electric push rod 61 is fixed on the surface of the bottom plate 2 located between the two tooth plates 63, and a connecting frame 62 is fixed to the extended end of the bidirectional electric push rod 61, and the two connecting frames 62 are fixedly connected to the corresponding tooth plates 63, the bottom plate 2 is located on the other side of the first rotating seat 21 and fixed with a second rotating seat 66, and a telescopic plate 67 is rotatably installed on the surface of the second rotating seat 66, and the bottom of the telescopic plate 67 is fixed toward one side of the tooth plate 63. There is an outer plate 65, and the front end of the tooth plate 63 is at a distance from the outer plate 65. The two-way electric push rod 61 pushes the connecting frame 62 and the tooth plate 63 to move. The two tooth plates 63 are engaged with the gear 64 to drive the hollow tube 3 to rotate, so that the hollow tube 3 can be monitored and warned of the environment in a vertical state, and the hollow tube 3 can also be folded. The length of the bottom plate 2 meets the requirement of the two hollow tubes 3 to fold in opposite directions, so that the internal structure can be stored and protected after being covered on the bottom plate 2 by the cover frame 22, so that people can enter the irrigation area to carry out planting work.

[0027] In this embodiment, a locking bolt 68 is threadedly inserted at the storage port of the telescopic plate 67, and the locking bolt 68 is pressed and contacted with the extended end of the telescopic plate 67. The backs of the first connection end 41 and the second connection end 42 are fixed with an insertion frame 46, and the upper and lower ends of the insertion frame 46 are hollowed out. An insertion block 69 is slidably inserted in the insertion frame 46, and the insertion block 69 is fixedly connected to the extended end of the telescopic plate 67. The anti-theft component 4 also includes a slide tube 44, and the slide tube 44 is fixed inside the first connection end 41 and the second connection end 42, and the slide tube 44 is slidably sleeved on the outer surface of the hollow tube 3. The top of the insertion frame 46 is fixed with a stopper. The first connecting end 41 and the second connecting end 42 are fixed with a rubber band 48 on the back side of the bottom plate 2, and the other end of the rubber band 48 is fixed on the surface of the bottom plate 2. The first connecting end 41 and the second connecting end 42 slide along the surface of the hollow tube 3 through the slide 44 to adjust it to a suitable height. For example, in the fruit tree area, the first connecting end 41 and the second connecting end 42 and the connecting line 43 need to be adjusted as high as possible. It is easy for people to tear off the connecting line 43 when stealing fruits, and for some high When the planting area is low, the position of the connecting line 43 is set slightly lower to prevent people from stepping into the planting area to steal. The height of the connecting line 43 is adjusted by manually adjusting the height of the telescopic plate 67. The telescopic plate 67 can be locked by the locking bolt 68. Then the plug block 69 is inserted into the insertion frame 46. At this time, the first connection end 41 and the second connection end 42 are pulled by the rubber band 48 and tend to move downward. The baffle plate 47 on the top of the insertion frame 46 is squeezed and contacted with the plug block 69 to keep the first connection end 41 and the second connection end 42 from moving downward. The position height, at the same time, the baffle plate 47 is only in contact with a part of the surface of the plug block 69. The dislocation can be achieved by squeezing with external force, which will neither interfere with the rotation of the hollow tube 3 nor affect the maintenance of the height of the first connecting end 41 and the second connecting end 42. When the hollow tube 3 rotates, the first connecting end 41 and the second connecting end 42 slide along the surface of the hollow tube 3 due to the elastic traction of the rubber band 48. When the hollow tube 3 is completely rotated to a horizontal state, the position of the connecting end can just meet the requirement that the connecting line 43 is still taut, avoiding the relaxation of the connecting line 43 to affect the covering of the cover frame 22 on the bottom plate 2. The technical principle between the first connecting end 41 and the second connecting end 42 and the connecting line 43 is the same as the principle of the existing disconnection alarm.

[0028] In this embodiment, the air detection component 5 also includes a filter plate 53, the filter plate 53 is rotated inside the dust box 52, and a weighing element 54 is fixedly installed at the bottom of the filter plate 53, and the weighing element 54 is in contact with the bottom of the filter plate 53, and a rotating drum 56 is fixed on the side of the dust box 52 facing the hollow tube 3, and the rotating drum 56 is rotatably installed on the outer surface of the hollow tube 3 through a bearing and a torsion spring, and a vertical plate 45 is fixed on the outer surface of the first connecting end 41 and the second connecting end 42, and a plug is fixed on the top of the vertical plate 45. The rotating drum 56 has a slot corresponding to the plug post 49, and the slot opening end of the rotating drum 56 is in the same rotation path as the hollow tube 3. When the hollow tube 3 is vertically arranged on the bottom plate 2, the plug post 49 of the vertical plate 45 is manually plugged into the slot of the rotating drum 56. The slot position is not shown in the figure, which is a common plug-in structure. The opening of the slot is in the same rotation path as the hollow tube 3, which means that when the plug post 49 is inserted into the slot, the hollow tube 3 does not rotate and fold, and the rotating drum 56 is always limited by the plug post 49. The method keeps the end of the fan 51 facing the planting area through the rotation of its own torsion spring. At the same time, when the hollow tube 3 is rotated and folded by the drive assembly 6, it will not be interfered by the rotating drum 56. After the plug 49 is separated from the slot, the rotating drum 56 rotates the fan 51 and the dust box 52 in a direction parallel to the base plate 2 through the action of the torsion spring, so as to facilitate the subsequent covering of all structures on the base plate 2 by the cover frame 22. The fan 51 can be powered by the wires sent into the hollow tube 3 to suck the air on the planting area into the dust box 52. The weight of the dust on the filter plate 53 can be monitored by the weighing element 54. If the dust weight is always in one area, it is normal. If the weight on the filter plate 53 obtained by the weighing element 54 increases sharply, it is possible that the air quality is very poor or a fire occurs and there are more ashes floating in the air. This situation will cause the alarm light 32 and the buzzer 31 to sound an early warning. The filter plate 53 of the dust box 52 can be turned over by the motor so that the accumulated dust can be sent out before each monitoring to maintain the accuracy of the weighing measurement.

[0029] When using the device, the optical fiber buried tube 1 is pre-buried underground, and the hollow tube 3 is connected to the optical fiber buried tube 1 through the metal hose 24. The hollow tube 3 can rotate at an angle, and the fixing bolt 23 is plugged into the socket 12 to realize the locking connection between the bottom plate 2 and the optical fiber buried tube 1, so that a section of the optical fiber buried tube 1 and a group of bottom plates 2 can be installed correspondingly. At the same time, the bottom plate 2 can be fixed to the ground through the fixing bolt 23. The first connecting end 41 and the second connecting end 42 slide along the surface of the hollow tube 3 through the slide cylinder 44 to adjust it to a suitable height. For example, in a fruit tree area, the first connecting end 41 and the second connecting end 42 and The connecting line 43 needs to be adjusted as high as possible, because it is easy for people to tear off the connecting line 43 when stealing fruits. For some areas with lower heights, the position of the connecting line 43 is set slightly lower to prevent people from stepping into the planting area to steal. The height of the connecting line 43 is adjusted by artificially adjusting the height of the telescopic plate 67. The telescopic plate 67 can be locked in length by the locking bolt 68, and then the plug block 69 is inserted into the insert frame 46. At this time, the first connecting end 41 and the second connecting end 42 are pulled by the rubber band 48 and tend to move downward, and the baffle 47 on the top of the insert frame 46 is squeezed and contacted with the plug block 69 to keep the first connecting end 4 1 and the second connection end 42 cannot move downward, the position height, and the baffle 47 only contacts with a part of the surface of the plug block 69, and can be dislocated by external force extrusion, which will neither interfere with the rotation of the hollow tube 3 nor affect the height maintenance of the first connection end 41 and the second connection end 42. When the hollow tube 3 rotates, the first connection end 41 and the second connection end 42 slide along the surface of the hollow tube 3 under the elastic traction of the rubber band 48. When the hollow tube 3 is completely rotated to a horizontal state, the position of the connection end can just meet the state that the connection line 43 is still tight, so as to avoid the relaxation of the connection line 43 affecting the cover frame 22 covering the bottom plate 2, and the fan 5 1 can be powered by the wire sent into the hollow tube 3, and the air above the planting area can be sucked into the dust box 52. The weight of the dust on the filter plate 53 can be monitored by the weighing element 54. If the dust weight is always within one area, it is normal. If the weight on the filter plate 53 obtained by the weighing element 54 increases sharply, it is possible that the air quality is very poor or a fire has occurred and there are many ashes floating in the air. This situation will cause the alarm light 32 and the buzzer 31 to warn. The filter plate 53 of the dust box 52 can be turned over by the motor so that the accumulated dust can be sent out before each monitoring to maintain the accuracy of the weighing measurement.
