[0002] Wetland refers to land with perennial accumulation of water and excessive moisture. Wetland is one of the most productive environments in the world and the cradle of biodiversity. Countless species of animals and plants depend on the water and primary productivity provided by wetlands for survival. Wetlands nurture highly concentrated species of birds, mammals, reptiles, amphibians, fish and invertebrate species and are also important storage places for plant genetic material. Wetlands are generally shallow areas with static or flowing water, such as natural or artificial swamps, and also include waters with a depth of no more than 6 meters at low tide. It is an important ecosystem.

During the wetland monitoring operation, after the deadweight increases due to the collection of water samples, the contact area between the floating components and the water area cannot be controlled, causing the restoration monitoring device to become unbalanced, and there is a risk of the monitoring device tipping over. Moreover, the functions of wetland ecosystem restoration monitoring equipment are generally simple, mainly by taking pictures of the ecosystem to obtain the wetland ecosystem restoration status of the area. However, the accuracy of the wetland restoration status is not guaranteed by simply taking pictures of the collected area with a camera, and sampling and testing of the wetland water source is required.

[0017] Compared with the prior art, the present invention provides a monitoring device for wetland water environment ecological restoration, which has the following beneficial effects:

[0018] 1.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Example:

[0032] Reference Figure 1-Figure 6 A monitoring device for wetland water environment ecological restoration includes a monitoring base 1 and a floating plate 2 in a circular array at the bottom of the monitoring base 1, a monitoring camera 16 is arranged on one side of the upper surface of the monitoring base 1, the monitoring camera 16 is electrically connected to a PLC, and an inclination sensor connected to the PLC electrical signal is arranged on the monitoring base 1;

[0033] The floating plate 2 is slidably arranged at the bottom of the monitoring base 1, and the fixed floating plate 4 is arranged in a circular equidistant array in the center of the bottom surface of the monitoring base 1. A telescopic floating plate 3 is connected between the floating plate 2 and the fixed floating plate 4. The floating plate 2 moves at the bottom of the monitoring base 1, driving the telescopic floating plate 3 to unfold;

[0034] In this embodiment, the monitoring base 1 is used to carry the monitoring camera 16 and other equipment for repair and monitoring. In order to facilitate the monitoring base 1 to move and monitor in the wetland water area, four groups of floating plates 2 are arranged at the bottom of the monitoring base 1. At the same time, in order to facilitate the adjustment of the floating plates 2 at the bottom of the monitoring base 1, thereby increasing the contact area between the monitoring base 1 and the water surface, the floating plates 2 are retractably connected to the bottom of the monitoring base 1 using fixed floating plates 4 and retractable floating plates 3. Taking into account the wetland water environment, during the wetland monitoring operation, the monitoring camera 16 can detect floating objects in time, receive and convert signals through PLC, and adjust the position of the floating plates 2, so as to unfold or retract the retractable floating plates 3, thereby adjusting the contact area between the floating components and the water surface, maintaining the balance of the monitoring device, and effectively avoiding the hidden danger of the monitoring device overturning due to scratches or collisions with floating objects when the monitoring device moves in the water area.

[0035] The monitoring base plate 1 is provided with guide grooves 12 at equal intervals in an annular shape. A moving block 6 is slidably installed in the guide groove 12 . The floating plate 2 is fixedly connected to the bottom of the moving block 6 through a connecting frame 5 .

[0036] Specifically, in this embodiment, considering that the moving block 6 may move frequently in the monitoring base 1, a guide groove 12 is provided in the monitoring base 1 to limit the moving block 6 to ensure horizontal movement of the floating plate 2 during the adjustment process.

[0037] Furthermore, the guide groove 12 is symmetrically provided with limiting grooves 13 , and the moving block 6 is symmetrically provided with guide blocks on both sides, and the guide blocks and the limiting grooves 13 are clearance-matched.

[0038] In the present embodiment, considering that when the moving block 6 and the guide groove 12 are in direct contact, the contact surface of the two parts is large, the friction force is also large, the movement of the moving block 6 generates resistance, and the floating plate 2 may be partially sunk into the water body, which may also generate resistance to the adjustment. Therefore, a limit groove 13 is opened to further limit the moving block 6, which not only ensures that the resistance to the movement of the moving block 6 is reduced as much as possible, but also ensures the stability of the movement of the moving block 6.

[0039] An internal threaded sleeve 8 is rotatably installed in the moving block 6 through a bearing, and a screw rod 7 is connected to the internal thread of the internal threaded sleeve 8. A passive bevel gear 11 is fixedly installed at one end of the screw rod 7. A first motor 9 is installed on the monitoring base plate 1 through a motor seat 15. An active bevel gear 10 is fixedly installed at the output shaft end of the first motor 9, and the active bevel gear 10 is meshed with the passive bevel gear 11.

[0040] In this embodiment, in order to enable the monitoring base 1 to achieve automatic adjustment and ensure that after the monitoring device leaves the operator's line of sight, the contact area between the floating component and the water area can still be adjusted according to the real-time environment of the monitoring site, thereby preventing the repair monitoring device from losing balance in the water area and avoiding the monitoring device from overturning.

[0041] Specifically, the monitoring camera 16 converts the real-time environment of the monitoring site collected by the PLC into data signals, and the signals are sent to the first motor 9. The rotation of the first motor 9 drives the active bevel gear 10 to rotate, and the rotation of the active bevel gear 10 drives the four sets of passive bevel gears 11 to rotate, thereby driving the screw rod 7 to rotate. Since the screw rod 7 is slidably connected to the moving block 6 through the internal threaded sleeve 8, the forward / reverse rotation of the first motor 9 is controlled to drive the screw rod 7 to rotate forward / reverse, thereby driving the moving block 6 to move in a concentrated / dispersed manner in the monitoring base plate 1, thereby driving the telescopic floating plate 3 to stretch / contract through the floating plate 2, thereby controlling the contact area between the floating part and the water area.

[0042] It should be noted that the surveillance camera 16 is set as a panoramic high-definition camera, model KJ-W2 (not limited to this model), relying on 5G, cloud computing and other technologies to realize the "radar-vision linkage" between the camera and the radar, and collect and analyze the target position and driving trajectory data tracked and scanned by the radar around the clock and at all times. It can monitor 24 hours a day and provide real-time feedback on the monitoring environment.

[0043] A second motor 17 is arranged on the upper surface of the monitoring base 1, and two sets of output shafts of the second motor 17 are fixedly connected with the driving shaft 18. One end of the driving shaft 18 is rotatably connected with the monitoring base 1 through the ear plate 27. Two sets of underwater driving rollers 21 are rotatably installed on the bottom surface of the monitoring base 1. Walking wheels 23 are arranged on the surface of the underwater driving rollers 21, and the walking wheels 23 are transmission-connected with the driving shaft 18.

[0044] In order to make the monitoring range of the monitoring device as large as possible and to be able to move freely away from the operator's line of sight, in this embodiment, a second motor 17 is arranged above the monitoring base 1, and two groups of underwater driving rollers 21 are symmetrically arranged on the front side of the bottom of the monitoring base 1. Traveling wheels 23 are arranged on the surface of the underwater driving rollers 21. When in use, the second motor 17 is started to drive the driving shafts 18 on both sides of the second motor 17 to rotate, and the driving shafts 18 drive the traveling wheels 23 to rotate, thereby driving the monitoring device to move in the water.

[0045] A walking part bracket 24 is fixedly installed on the lower surface of the monitoring base 1, and the underwater driving roller 21 is rotatably installed in the walking part bracket 24. A connecting shaft 25 is fixedly connected between the two groups of underwater driving rollers 21. A driving pulley 19 is fixedly installed on the surface of the driving shaft 18. The two groups of walking wheels 23 are transmission-connected with a passive pulley 22. The passive pulley 22 and the active pulley 19 are transmission-connected through a transmission belt 20. The passive pulley 22 is fixedly installed on the end of the connecting shaft 25. A yield groove 26 is opened in the monitoring base 1, and the transmission belt 20 runs through the yield groove 26.

[0046] Specifically, in the present embodiment, two groups of walking part brackets 24 are used to support the underwater driving roller 21, and the two groups of underwater driving rollers 21 are connected by a connecting shaft 25. A driving pulley 19 is fixedly installed at one end of the driving shaft 18, and a passive pulley 22 is fixedly installed at the end of the underwater driving roller 21. The driving pulley 19 and the passive pulley 22 are connected by a transmission belt 20. In order to protect the normal operation of the second motor 17 and extend the service life of the second motor 17 as long as possible, the second motor 17 is arranged above the monitoring base 1, and the transmission belt 20 passes through the upper side of the monitoring base 1 to the lower side of the monitoring base 1 via the give way groove 26, so that the driving pulley 19 and the passive pulley 22 are connected by transmission, thereby ensuring that the walking wheel 23 drives the monitoring base 1 to walk in the water.

[0047] Two groups of sampling parts are symmetrically arranged on the monitoring base 1, and the sampling parts are provided with sampling hoses 32 of different lengths. In this embodiment, sampling hoses 32 of different lengths are used to absorb different water layers or even the bottom of the water in the same water area, which is convenient for subsequent detection, thereby carrying out necessary restoration and all-round monitoring of the wetland water environment ecology.

[0048] It should be noted that the number of the sampling hoses 32 is set according to the volume of the water sample that the monitoring base 1 can carry.

[0049] Two sets of sampling parts are arranged in the monitoring base 1, and the two sets of sampling parts are symmetrically arranged on both sides of the tail of the monitoring base 1. Compared with the sampling parts, the walking wheels 23 are located at the head below the monitoring base 1, and the sampling parts and the walking parts can be used to balance the entire monitoring device. During the movement of the monitoring device, the sampling hose 32 can enter different water areas to absorb water samples in the water area. It should be noted that the sampling hose 32 is set to different lengths, so that different water layers or even the bottom of the water in the same water area can be absorbed, which is convenient for subsequent detection, thereby carrying out necessary restoration and all-round monitoring of the wetland water environment ecology.

[0050] The sampling part also includes a sampling bracket 14, in which a water storage pipe 30 is arranged. The bottom end of the water storage pipe 30 is connected to a valve 31. The sampling hose 32 is connected to the water storage pipe 30 through the valve 31. A filter block 33 is fixedly installed at the water inlet end of the sampling hose 32. The material of the filter block 33 is set to a stainless steel mesh plate.

[0051] Specifically, in this embodiment, the sampling hose 32 is installed in the sampling bracket 14, and the sampling bracket 14 is fixedly connected to both sides of the monitoring base plate 1. A valve 31 is connected in the sampling hose 32, and the valve 31 is used to control the opening and closing of the sampling hose 32, so that the sampling hose 32 can absorb water samples in any water area.

[0052] At the same time, a filter block 33 is arranged at the bottom of the sampling hose 32. The filter block 33 is made of a stainless steel mesh plate that is bent and welded into a hollow block structure with a through hole. In the process of absorbing water samples, large particles of stone and soil are prevented from entering the sampling hose 32. No secondary filtration is required, which reduces the intensity of manual work and can also avoid damage to the detection equipment during subsequent ecological restoration.

[0053] The sampling bracket 14 is arranged in an open structure with upper and lower penetrations, and a water hole 29 is provided at one end of the sampling bracket 14 away from the walking wheel 23, a support sleeve 44 is sleeved on the surface of the water storage pipe 30, and the support sleeve 44 is connected to a support rod 43, and the support sleeve 44 is fixedly connected to the inner wall of the sampling bracket 14 through the support rod 43.

[0054] In this embodiment, the sampling bracket 14 is arranged with an open structure at the top and bottom, and a water hole 29 is opened at one end of the sampling bracket 14, which can not only reduce the weight of the monitoring device, but also reduce the resistance of the sampling bracket 14 in the water during the forward movement of the monitoring base 1.

[0055] In this embodiment, the support rod 43 is used to connect the support sleeve 44, and the water storage pipe 30 is clamped in the support sleeve 44. After sampling, it is convenient for the operator to take the water storage pipe 30 out of the sampling bracket 14 to obtain the water sample.

[0056] A liquid level gauge 46 is provided on the top of the water storage pipe 30 , and a connecting pipe 34 is connected between two adjacent groups of water storage pipes 30 . The connecting pipe 34 is connected to the water pumping pipe 35 through the first branch pipe 40 , the second branch pipe 41 and the third branch pipe 42 .

[0057] In this embodiment, a liquid level meter 46 is provided at the top of the water storage pipe 30. When the water sample in the water storage pipe 30 reaches the measurement set by the operator, the liquid level meter 46 feeds back a signal to the PLC, and the valve 31 can be closed to stop the suction action of the sampling hose 32.

[0058] An eccentric roller 28 is fixedly mounted on the surface of the driving shaft 18, an airbag 36 is arranged between the driving shaft 18 and the upper surface of the monitoring base 1, the upper and lower sides of the airbag 36 are respectively connected to a top plate 37 and a bottom plate 38, the bottom plate 38 is fixedly connected to the monitoring base 1, the upper surface of the top plate 37 and the outer surface of the eccentric roller 28 are fitted together, four groups of springs 39 are arranged between the top plate 37 and the bottom plate 38, the airbag 36 is connected to one end of the water pumping pipe 35, and an exhaust valve 45 is arranged on one side of the airbag 36.

[0059] In this embodiment, an eccentric roller 28 is provided on the surface of the driving shaft 18, and an airbag 36 is provided at the bottom of the eccentric roller 28. During the rotation of the eccentric roller 28, the airbag 36 is squeezed, and the airbag 36 is connected to the sampling hose 32. Therefore, by squeezing the airbag 36, the water sample in the water can be sucked into the water storage pipe 30.

[0060] It should be noted that during the movement of the monitoring base 1, the drive shaft 18 rotates continuously and continuously squeezes the airbag 36. Since the eccentric roller 28 is set as an eccentric structure, after one rotation, the eccentric roller 28 with a large radius has the maximum squeezing stroke on the airbag 36, completing one squeezing operation. It should be noted that the valve 31 is a one-way valve, and the inhaled water sample will not be discharged due to secondary squeezing.

[0061] It should be noted that the lengths of the sampling hoses 32 connected to the first branch pipe 40 , the second branch pipe 41 and the third branch pipe 42 are successively lengthened to absorb different water layers or even the bottom of the water in the same water area.

[0062] Specifically, the valve 31 in the sampling hose 32 connected to the second branch 41 and the third branch 42 is initially closed. When the water storage pipe 30 connected to the first branch 40 absorbs a set amount of water sample, the valve 31 connected thereto is closed, and the valve 31 in the sampling hose 32 connected to the second branch 41 is opened to absorb water samples from another layer of water area, and so on, until the water storage pipe 30 connected to the third branch 42 completes sampling, thereby realizing the absorption of water samples from different water areas and water layers.

[0063] When all water storage pipes 30 have completed sampling, the exhaust valve 45 on the top of the airbag 36 is opened, and the airbag 36 is compressed. This will not affect the movement of the monitoring base plate 1 in the water and will not increase the pressure in the water storage pipe 30, ensuring that the water storage pipe 30 is not affected before the monitoring base plate 1 is returned to the operator.

[0064] In this embodiment, the driving force of the walking part is utilized to effectively reciprocate and compress the airbag 36, so that during the movement, water samples from as many water areas as possible can be absorbed within the largest possible monitoring range, further improving the sampling range of the monitoring device, and better monitoring and timely repair of the wetland water environment ecology.

[0065] It should be noted that, by arranging an inclination sensor in the monitoring base plate 1, the inclination sensor and the PLC data signal in the monitoring device are connected. After the water storage pipe 30 is sucked, the deadweight of the monitoring device will increase accordingly. After the inclination sensor transmits a signal, the PLC controls the first motor 9 to drive the bevel gear transmission, thereby adjusting the position of the floating board 2, thereby changing the contact area between the floating part and the water area, until the signal of the inclination sensor restores the data of the balanced state, the first motor 9 stops, and the monitoring device continues to monitor the work through the monitoring camera 16, or returns to the operator.

[0066] It should be noted that the tilt sensor model is SCA116T, which monitors and feeds back the balance parameters of the monitoring base 1 in the water area, and adjusts the contact area between the floating part and the water area in time through PLC control, so as to ensure the balance of the device and prevent it from overturning.

[0067] In the present invention, in the initial state, the monitoring base 1 and the monitoring device formed by the mechanical structure carried by the monitoring base 1 are placed in the wetland waters, and the PLC, monitoring camera 16 and inclination sensor in the monitoring base 1 are started. First, the balance of the monitoring base 1 is sensed by the inclination sensor, and the signal is transmitted to the PLC. The signal data is converted by the PLC to control the first motor 9 to start. The first motor 9 rotates to drive the active bevel gear 10 to rotate, and the active bevel gear 10 rotates to drive the four sets of passive bevel gears 11 to rotate, thereby driving the screw rod 7 to rotate. Since the screw rod 7 is slidably connected to the moving block 6 through the internal threaded sleeve 8, the screw rod 7 rotates forward / reverse, driving the moving block 6 to move in a concentrated / dispersed manner in the monitoring base 1, and the telescopic floating plate 3 is stretched / contracted through the floating plate 2, thereby controlling the contact area between the floating part and the waters, ensuring the balance of the entire monitoring device in the waters, thereby ensuring the normal operation of the monitoring device;

[0068] The second motor 17 is started to drive the driving shafts 18 on both sides of the second motor 17 to rotate, and the driving shafts 18 drive the running wheels 23 to rotate, thereby driving the monitoring device to move in the water, thereby increasing the moving range of the monitoring base 1 in the water area;

[0069] At the same time, the eccentric roller 28 is fixedly mounted on the surface of the driving shaft 18. During the movement of the monitoring base plate 1, the eccentric roller 28 rotates accordingly to squeeze the airbag 36. The airbag 36 is connected to the sampling hose 32. Therefore, squeezing the airbag 36 can suck the water sample into the water storage pipe 30.

[0070] The valve 31 in the sampling hose 32 connected to the second branch pipe 41 and the third branch pipe 42 is initially closed. When the water storage pipe 30 connected to the first branch pipe 40 absorbs a set amount of water sample, the valve 31 connected to it is closed, and the valve 31 in the sampling hose 32 connected to the second branch pipe 41 is opened to absorb water sample from another layer of water area, and so on, until the water storage pipe 30 connected to the third branch pipe 42 completes sampling, thereby realizing the absorption of water samples from different water areas and water layers;

[0071] When all water storage pipes 30 have completed sampling, the exhaust valve 45 on the top of the airbag 36 is opened, and the airbag 36 is compressed. This will not affect the movement of the monitoring base plate 1 in the water and will not increase the pressure in the water storage pipe 30, ensuring that the water storage pipe 30 is not affected before the monitoring base plate 1 is returned to the operator.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
