DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Example

[0027] In view of the problems raised in the above background technology, this embodiment provides a surface water resource carrying capacity monitoring and early warning system with unique structure and ingenious design, such as Figure 1-5As shown, it includes a monitoring ship 1, a monitoring controller, a detection unit, a traction adjustment unit 4 and an early warning unit. The bottom of the monitoring ship 1 is provided with an air cavity 21 with an open bottom. There is air in the air cavity 21, so that the internal space of the air cavity 21 will not be flooded by water. There are many ways to set the air cavity 21. For example: a detection box 2 with an open bottom is vertically installed in the monitoring ship 1. The detection box 2 penetrates the bottom of the monitoring ship 1 downward, and the edge of the detection box 2 is sealed and connected to the bottom of the ship. The internal space of the detection box 2 is the air cavity 21.

[0028] The detection unit includes a front frame 41, a rear frame 42 and a sensor group. Two fixed shafts 43 are arranged in parallel in the longitudinal direction in the air cavity 21. The top ends of the front frame 41 and the rear frame 42 are respectively rotatably mounted on the front and rear fixed shafts 43. A plurality of platform plates 44 are evenly spaced in the front frame 41 along the setting direction of the front frame 41. The platform plates 44 are arranged parallel to the horizontal plane where the two fixed shafts 43 are located. The platform plates 44 are rotatably installed in the front frame 41, and the rear end of the platform plates 44 is hinged to the rear frame 42. The front frame 41 and the rear frame 42 are connected together through the platform plates 44 to form a parallelogram structure detection frame. Specifically: like Figure 2-3 As shown, the front frame 41 includes two front main rods 411 arranged in parallel and at intervals in the transverse direction, the top ends of the two front main rods 411 are rotatably mounted on the front fixed shaft 43, and the tail ends of the two front main rods 411 are fixedly connected together and connected to the traction adjustment unit 4, and a plurality of rotating shafts 412 are arranged in parallel and at intervals between the two front main rods 411, and the central axes of the plurality of rotating shafts 412 are in the same straight line with the central axis of the front fixed shaft 43, and the two ends of the rotating shaft 412 are respectively vertically connected to the front main rods 411 on the adjacent sides, and the middle part of the platform plate 44 is provided with an axis hole and is rotatably mounted on the corresponding rotating shaft 412, and the tail end of the platform plate 44 is hinged to the rear frame 42, and the rear frame The frame 42 includes two rear auxiliary rods 421 arranged in parallel and at intervals along the transverse direction. The top ends of the two rear auxiliary rods 421 are rotatably mounted on the rear fixed shaft 43. The tail ends on the left and right sides of the platform plate 44 are respectively hinged to the adjacent side rear auxiliary rods 421, and the rear auxiliary rods 421 and the front main rod 411 are arranged parallel to each other, so that the front frame 41 and the rear frame 42 are connected together through the platform plate 44 to form a parallelogram structure detection frame, so that when the front frame 41 is driven to flip forward around the front fixed shaft 43 toward the air cavity 21, the front frame 41 will drive the rear frame 42 to flip forward around the rear fixed shaft 43 toward the air cavity 21 through the platform plate 44.

[0029] The tail end of the front frame 41 is connected to the traction adjustment unit 4. The controller can drive the front frame 41 to flip forward and upward around the top end and store it in the air cavity 21 through the traction adjustment unit 4. The traction adjustment unit 4 has various structures. For example, in this embodiment, the traction adjustment unit 4 includes a hoisting device and a water depth sensor. The hoisting device is installed on the inner wall of the front cavity of the air cavity 21 above the fixed shaft 43 and is connected to the detection controller. A traction rope is wound in the hoisting device, and the traction end of the traction rope is connected to the tail end of the front frame 41. The water depth sensor is installed on the bottom of the ship at the front or rear side of the air cavity 21 and is connected to the monitoring controller. The monitoring controller controls the release length of the traction rope of the hoisting device according to the water depth detected by the water depth sensor. When the hoisting device releases the traction rope, the tail end of the detection frame will automatically turn around the top and extend out of the air cavity 21 to be immersed in the water. During this process, each platform plate 44 will remain parallel. Therefore, when the tail end of the detection frame touches the bottom, since the platform plates 44 are evenly spaced, each platform plate 44 divides the water body into multiple detection areas evenly according to the depth; when the hoisting device releases the traction rope, the traction rope will pull the tail end of the detection frame upward, so that it will rotate upward around the top and be recovered to the air to separate the inside from the water.

[0030] A sensor group is installed on each platform plate 44, and the sensor group is connected to the monitoring controller for detecting the water quality data of the water layer where the platform plate 44 is located. The sensor group includes a plurality of water quality sensors embedded in the upper end surface of the platform plate 44, and the water quality sensors are connected to the monitoring controller for detecting different water quality parameters; the early warning unit is connected to the monitoring controller, and when the water quality data exceeds the safety value, the controller will control the early warning unit to send out an early warning signal, and the early warning unit includes an early warning control module and a signal transmission module, and the early warning control module is connected to the monitoring controller for analyzing the water quality data transmitted by the sensor group to determine whether it exceeds the preset safety threshold; when the water quality data exceeds the safety value, the early warning signal is triggered; the signal transmission module includes an audible and visual alarm and a wireless signal transmitter, and the audible and visual alarm is connected to the monitoring controller for sending an audible and visual alarm when the water quality data exceeds the safety value, and the wireless signal transmitter is connected to the monitoring controller for sending the early warning signal to the remote monitoring center or the mobile device of the management personnel.

[0031] When in use, the monitoring controller can control the depth below the detection frame according to the water depth by pulling the adjustment unit 4, and use the platform plate 44 to evenly divide the water body into multiple detection areas. At the same time, water bodies in different areas are detected, thereby improving the accuracy of water quality detection results and realizing all-round monitoring of water quality. In addition, since the platform plate 44 is horizontally arranged, when performing detection, the water bodies detected by each water quality sensor on the platform plate 44 are the same, which can effectively reduce errors. After the monitoring is completed, since the air cavity 21 is arranged downward and there is air in the air cavity 21, the internal space of the air cavity 21 will not be submerged in water. Therefore, after the detection unit is stored in the air cavity 21 by pulling the adjustment unit 4, the detection sensor group will be separated from the water body, thereby increasing the service life. Example

[0032] The difference between Example 2 and Example 1 is that the inner end surfaces of the two rear auxiliary rods 421 are respectively flush with the inner end surfaces of the front main rods 411 adjacent to the front side, and the inner end surfaces of the two rear auxiliary rods 421 are installed with connecting components, and the rear auxiliary rods 421 are rotatably sleeved on the fixed shaft 43 through the connecting components and are hinged with the corresponding platform plate 44. Figure 4 As shown, the connection components It includes a main connecting seat 422 vertically and cross-mounted at the top of the rear auxiliary rod 421, the main connecting seat 422 extends the rear auxiliary rod 421 forward, and is rotatably mounted on the rear fixed shaft 43, a plurality of auxiliary connecting seats are arranged on the rear auxiliary rod 421 below the main connecting seat 422 along the vertical interval, the auxiliary connecting seats are vertically and cross-fixed on the inner end surface of the rear auxiliary rod 421, that is, the end surface of the rear auxiliary rod 421 facing the other side; the auxiliary connecting seat protrudes forward from the rear auxiliary rod 421 and is provided with an axial hole, the left and right tail ends of the platform plate 44 are provided with notches matching the auxiliary connecting seat, the end surface of the notch facing outward is matched with a pin shaft, the auxiliary connecting seat is matched and inserted into the notch on the adjacent side of the front platform plate 44, and is rotatably mounted on On the pin shaft in the notch, the front frame 41 and the rear frame 42 are connected together through the platform plate 44 to form a parallelogram structure detection frame, and the vertical distance dimension between the central axis of the shaft hole on the sub-connecting seat and the front end surface of the rear auxiliary rod 421 is a, and the vertical distance dimension between the central axis of the rotating shaft 412 and the rear end surface of the front main rod 411 is b, where a=b, so that during use, when the tail end of the detection frame is lifted into the air cavity 21 by the traction adjustment unit 4, the sub-connecting seats on the rear frame 42 can be inserted into the front frame 41, so that the lower part of the rear frame is in contact with the lower part of the front frame, so that it is horizontally stored in the air cavity 21. Compared with the inclined storage of the detection frame, the space required for horizontal storage is small.

[0033] Furthermore, a positioning block 5 is matched and installed on the cavity top of the air cavity 21 . When the front frame 41 turns forward around the front fixed axis 43 toward the air cavity 21 and contacts the positioning block 5 , the rear frame 42 and the front frame 41 contact each other synchronously. Example

[0034] The difference between Example 3 and Example 2 is that a cleaning unit is matched in the air wall, such as Figure 6 As shown, the cleaning unit includes a plurality of cleaning modules spaced apart in the air cavity 21 at the rear side of the positioning block 5 , and the number and position of the cleaning modules correspond to the number and position of the platform plate 44 .

[0035] The cleaning module includes a water tank 6, a water pipe and a wiping block 62. The water tank 6 is arranged above the front side of the platform plate 44 in the storage state. The water tank 6 is connected to a water supply device through a water pipe. The water supply device is installed on the monitoring ship 1 to replenish cleaning water into the water tank 6. A drainage port is provided laterally on the rear end face of the water tank 6. The wiping block 62 is horizontally slidably installed in the air cavity 21 on the rear side of the water tank 6, and is connected to a driving mechanism for transmission. When the frame flips forward around the front fixed axis 43 toward the air cavity 21 and collides with the positioning block 5, the upper end face of the platform plate 44 collides with the wiping block 62.

[0036] The driving mechanism is connected to the monitoring controller, and the monitoring controller can drive the wiping block 62 to move horizontally to wipe the upper end surface of the platform plate 44 through the driving mechanism. A protrusion matching the drain outlet of the water tank 6 is provided at the front end of the wiping block 62. When the monitoring controller drives the wiping block 62 forward to contact the water tank 6 through the driving mechanism, the protrusion on the wiping block 62 will block the drain outlet of the water tank 6; thus, after the detection frame is recovered into the air cavity 21, the monitoring controller drives the wiping block 62 backward to wipe the upper end surface of the platform plate 44 through the driving mechanism. As the wiping block 62 moves, the clean water in the water tank 6 will flow to the platform plate 44 through the drain outlet to rinse the upper end surface of the platform plate 44 and the detection end of the water quality sensor.

[0037] There are many ways to slide and install the wiping block 62. For example, wiping seats are symmetrically installed on the left and right ends of the wiping block 62. The wiping seats are slidably installed on the inner wall of the air cavity 21 on the adjacent side along the longitudinal direction. The driving mechanism includes a driving screw and a driving motor. A threaded hole that penetrates the seat body is provided along the longitudinal direction of the wiping seat on one side of the wiping block 62. The driving screw is matched and sleeved in the threaded hole. Both ends of the driving screw are rotatably installed on the inner wall of the air cavity 21 through bearing seats. The driving screw is connected to the driving motor in transmission. When the driving motor is working, it will drive the wiping seat to drive the wiping block 62 to move through the driving screw. Example

[0038] The difference between Example 4 and Example 3 is that the cleaning unit structure is different.

[0039] like Figure 7-9 As shown, the cleaning unit includes a water supply device, an air supply device, a cleaning device, a linkage adjustment device and a traction device. The cleaning device includes a cleaning roller, a movable seat, a supply mechanism and a linkage adjustment mechanism. A movable seat 71 is symmetrically installed on the inner walls on the left and right sides of the air cavity above the front side of the fixed shaft for sliding along the longitudinal direction, and a cleaning roller 72 is arranged horizontally between the two movable seats. Roller shafts 721 are symmetrically installed on the left and right sides of the cleaning roller, and a cavity is axially arranged inside the cleaning roller, and the cavity is connected with the output end of the supply device and the water supply device; bristles are arranged on the outer ring surface of the cleaning roller, and a plurality of output holes 722 connected with the internal cavity are arranged on the axial uniform parts on the outer ring surface of the cleaning roller, and the roller shaft on one side of the cleaning roller is directly rotatably inserted into the movable seat on the adjacent side, and the roller shaft 721 on the other side of the cleaning roller is rotatably connected with the movable seat on the adjacent side through the supply mechanism, and the linkage adjustment mechanism is installed on the movable seat on the same side of the supply mechanism, and is transmission-connected with the supply mechanism, and when the movable seat is driven to move the cleaning roller through the linkage adjustment mechanism, the linkage adjustment mechanism will first cause the cleaning roller to rotate a fixed angle, so that the output hole on the cleaning roller is inclined downward in the moving direction.

[0040] The supply mechanism includes a supply shaft 73 fixedly mounted on the roller shaft of the cleaning roller, and the end of the supply shaft 73 away from the cleaning roller is rotatably mounted on the movable seat on the same side; the linkage adjustment mechanism includes a base 75 mounted on the bottom of the movable seat in a longitudinal sliding manner, and the base is connected to a traction component in a transmission manner. The monitoring controller can drive the base to move longitudinally in the air cavity through the traction component, and when the base slides to the limit position along the movable seat, the traction component will drive the base to drive the movable seat to slide synchronously. Specifically: A dovetail-shaped track groove is provided in the longitudinal direction on the base, and a dovetail-shaped slider 741 is matched and installed in the anti-slip track groove. The slider extends upward out of the base and is fixedly connected to the bottom surface of the movable seat 71. A rack 742 is installed in the longitudinal direction on the base below the supply shaft 73, and a gear 743 is fixedly mounted on the supply shaft above the rack. The gear meshes with the rack, and a limit block 744 is matched and installed on the base on the front and rear sides of the connecting seat to restrict the sliding range of the base, and the resistance of driving the cleaning roller to rotate by pulling the base is less than the resistance of driving the movable seat to drive the cleaning roller to move longitudinally. When the detection frame is recovered into the air cavity, the platform plate located at the front side of the detection frame will collide with the bristles on the cleaning roller, so that when the monitoring controller controls the driving component to drive the base to move backward, the cleaning roller will move backward to clean the platform plate in the detection frame. When cleaning, the controller will synchronously control the water supply device to start. During this process, the rack will drive the cleaning roller to rotate before the cleaning roller moves, so that the output hole on the cleaning roller is set backward and downward. When the cleaning roller moves backward to clean the platform plate in the detection frame, the clean water injected into the cleaning roller will be sprayed out from the output hole to rinse the platform plate first, making it easier for the brush to clean the platform plate; when the monitoring controller controls the driving component to drive the base to move forward and reset, the shift controller will synchronously control the air supply device to start. During this process, the rack on the base will drive the cleaning roller to rotate in the opposite direction at a certain angle before the cleaning roller moves, so that the output hole on the cleaning roller is set forward and downward. When the cleaning roller moves forward and resets, the high-pressure gas injected into the cleaning roller will be sprayed out from the output hole to flush the platform plate first, dry the liquid accumulated on the platform plate, and prevent liquid residue.

[0041] There are many ways to slide the movable seat on the inner wall of the air cavity, for example: a guide rail is installed horizontally along the upper edge of the inner wall of the air cavity on the front side above the fixed shaft, a sliding seat is matched and installed in the guide rail, the sliding seat extends outward from the guide rail and is fixedly connected to the connecting seat; the traction assembly of this embodiment adopts a screw drive structure, including a bearing seat, a screw and a driving motor connected to the monitoring controller. A threaded hole 751 is provided in the middle of the base along the longitudinal direction, the screw is matched and installed in the threaded hole, and the two ends of the screw are respectively fixedly installed on the front and rear sides of the detection frame in the storage state through the bearing seat. The driving motor is installed in the air cavity and is connected to the screw transmission. When the screw rotates, it will drive the base to move synchronously. Example

[0042] The difference between Example 5 and Example 4 is that the water supply device includes a high-pressure water tank installed on the monitoring ship, the air supply device includes a high-pressure air tank installed on the monitoring ship, when the cleaning roller is in the initial state, the cleaning roller is automatically disconnected from the air supply device and the water supply device, when the cleaning roller moves backward, the cleaning roller is automatically disconnected from the air supply device, and when the cleaning roller moves forward, the cleaning roller is automatically disconnected from the water supply device. Specifically: like Fig. 9As shown, one end face of the supply shaft facing the movable seat is in sealing contact with the end face of the movable seat, and an input channel connected to the internal cavity of the cleaning roller is axially arranged on the end face of the supply shaft facing the movable seat, and the input channel is arranged away from the axis of the supply shaft, and an air channel and a liquid channel are arranged at intervals along the circumferential direction around the axis of the supply shaft on the end face of the movable seat in sealing contact with the supply shaft, and in the initial state of the supply shaft, the input channel is located between the air channel and the liquid channel, and the outer ports of the air channel and the liquid channel are blocked by the end face of the supply shaft, specifically: When the cleaning roller is in the initial state, the middle teeth of the gear and the rack are meshed. At this time, the input channel on the supply shaft is located between the air channel and the liquid channel, and the outer openings of the air channel and the liquid channel are blocked by the end face of the supply shaft; when the base drives the movable seat to move backward, the supply shaft will be driven to rotate counterclockwise to the extreme position, so that the outer opening of the input channel on the supply shaft is connected with the outer opening of the liquid channel on the movable seat. Conversely, when the base drives the movable seat to move forward, the supply shaft will be driven to rotate clockwise to the extreme position, so that the outer opening of the input channel on the supply shaft is connected with the outer opening of the air channel on the movable seat.
