Description

Technical Field

[0001] The present invention relates to the technical field of water body monitoring equipment, and particularly to a water environment monitoring device. Background Art

[0002] Water environment monitoring takes the water environment as the object, and uses physical, chemical and biological technical means to qualitatively, quantitatively and systematically comprehensively analyze the pollutants and their related components therein, so as to explore and study the changing laws of the water environment quality. Water environment monitoring provides reliable basic data for water environment management and scientific basis for the evaluation of the effects of treatment measures.

[0003] Chinese Patent Grant Publication No.: CN101776676B discloses a mobile on-line comprehensive water body monitoring buoy. The working principle of the mobile on-line comprehensive water body monitoring buoy of the present invention is as follows: The solar photovoltaic conversion panel converts solar energy into electrical energy, which is stored in the solar storage battery. Through the power management module, it is managed to provide energy in the form of direct current to the embedded computer, the power control drive board (including the directional electronic compass), the sensor signal conditioning and analog-to-digital conversion board, the GPS module, the GPRS module, the direction-adjusting functional thruster, the power-type thruster, etc. The data collected by the water body monitoring sensor and the micro meteorological station can be processed by the embedded computer and transmitted to the remote monitoring system through the GPRS wireless communication method. When the buoy receives the position information of the buoy target area from the remote monitoring system, the embedded computer can plan the corresponding movement trajectory by combining the current position information obtained by the GPS module and the directional information (geographical north pole position) of the electronic compass, and then drive the corresponding thruster to act through the power control drive board (including the directional electronic compass), and adjust the rotation speed of each thruster through the internal algorithm to realize the automatic control of the all-round movement of the buoy. All power consumption can be provided by the solar storage battery without external power supply.

[0004] In view of the above related technologies, the water body monitoring buoy plans the corresponding movement trajectory through the current position information obtained by the GPS module and the directional information of the electronic compass to control the movement trajectory and direction of the water body monitoring buoy. However, the water body monitoring buoy can only be used in an environment with good satellite signals. When monitoring the environment of cave water bodies, long-term monitoring of cave water bodies at different time periods is required to obtain accurate data on the water environment in the cave. Due to the extremely poor satellite signals in the cave, the water body monitoring buoy cannot move along the correct movement trajectory. Summary of the Invention

[0005] In view of the above technical problems, the present invention provides a water environment monitoring device, including:

[0006] A floating body, having buoyancy and used for floating on the water body;

[0007] A water body monitoring device is installed on a floating body and is used for monitoring the water body environment;

[0008] A rack penetrates through the floating body and is used for being arranged in the cave water body;

[0009] A first gear meshes with the rack and is rotatably connected to the floating body;

[0010] A limiting device is installed on the floating body and contacts with the rack, and is used for limiting the rack so that the first gear remains meshed with the rack;

[0011] A first driving device is installed on the floating body and is drivingly connected to the first gear, and is used for driving the first gear to rotate, so as to drive the floating body to move along the length extension direction of the rack.

[0012] To achieve the above object, the present invention is realized through the following technical solutions: When environmental monitoring of a cave water body with a complex path is required, the rack is arranged along the path of the cave water body, the first driving device drives the first gear to rotate, under the limiting action of the limiting device, the first gear drives the rack to move relative to the floating body, the rack generates a pulling force on the floating body, so that the floating body moves in the water body along the length direction of the rack, and at the same time, the water body monitoring device completes the monitoring of the water body environment.

[0013] Compared with the prior art, the present invention has the following advantages: In a cave water body without satellite signals and with a complex path, the floating body drives the water body monitoring device to move along the correct path and complete the monitoring of the water body environment in the cave.

[0014] Further preferably, the rack is a double-sided rack, and the limiting device includes:

[0015] A second gear is rotatably connected to the floating body and is located on both sides of the rack respectively with the first gear.

[0016] Adopting the above technical solution, the second gear cooperates with the first gear to clamp the rack, so as to limit the rack, and at the same time, the second gear can rotate to reduce the resistance of the rack movement.

[0017] Further preferably, the first driving device includes:

[0018] A third gear is coaxially and fixedly connected to the first gear;

[0019] A fourth gear is coaxially and fixedly connected to the second gear;

[0020] A worm is rotatably connected to the floating body and meshes with the third gear;

[0021] A driving motor is installed on the floating body and is drivingly connected to the worm, and is used for driving the worm to rotate.

[0022] With the above technical solution, the driving motor drives the worm to rotate. The third gear is a worm gear. Since the worm gear is a special gear, the worm drives the third gear to rotate. The third gear drives the first gear to rotate. At the same time, the third gear drives the fourth gear to rotate, and the fourth gear drives the second gear to rotate, so that the first gear and the second gear rotate synchronously. The first gear and the second gear pull the rack at the same time, avoiding wear on one side of the rack. The meshing of the worm and the gear has a self-locking function. When it is necessary to stop the movement of the water body monitoring device, when the worm stops rotating, the gear cannot rotate, which can make the floating body stop moving and improve the stability of the water body monitoring device during water environment monitoring.

[0023] Further preferably, it further includes:

[0024] The first swing rod, the end of which is rotatably connected to the floating body;

[0025] The roller, which is rotatably connected to the first swing rod and is installed at one end of the first swing rod away from the floating body for contacting the inner wall of the cave;

[0026] The second driving device, which is installed on the floating body and is drivingly connected to the first swing rod for driving the first swing rod to swing, thereby driving the roller to swing.

[0027] With the above technical solution, when there is a turning path in the cave water body, the length extension direction of the rack also turns. The second driving device drives the first swing rod to swing, and the first swing rod drives the roller to swing towards the inner side of the bending arc of the rack. The roller contacts the inner wall of the cave, avoiding the collision between the floating body and the inner wall of the cave and prolonging the service life of the floating body.

[0028] Further preferably, the second driving device includes:

[0029] The second swing rod, the end of which is rotatably connected to the floating body;

[0030] The elastic member, one end of which is connected to the first swing rod and the other end is connected to the second swing rod, for applying a force to the first swing rod and the second swing rod to make the first swing rod and the second swing rod approach each other;

[0031] The first limiting block, which is fixedly connected to the floating body and is in contact and cooperation with the first swing rod;

[0032] The second limiting block, which is fixedly connected to the floating body, is in contact and cooperation with the first swing rod, and is respectively arranged on both sides of the first swing rod with the first limiting block for limiting the swinging amplitude of the first swing rod;

[0033] The third limiting block, which is fixedly connected to the floating body and is in contact and cooperation with the second swing rod;

[0034] The fourth limiting block, which is fixedly connected to the floating body, is in contact and cooperation with the second swing rod, and is respectively arranged on both sides of the first swing rod with the third limiting block for limiting the swinging amplitude of the first swing rod;

[0035] The driving component is installed on the floating body and is used to drive the first swing rod to swing.

[0036] With the above technical solution, the driving component drives the first swing rod to swing. When the first swing rod separates from the first limiting block, the elastic member is stretched. When the first swing rod contacts the second limiting block, under the action of the elastic force of the elastic member, the second swing rod separates from the third limiting block and swings until the second swing rod contacts the fourth limiting block.

[0037] The driving component drives the first swing rod to swing. When the first swing rod separates from the second limiting block, the elastic member is stretched. When the first swing rod contacts the first limiting block, under the action of the elastic force of the elastic member, the second swing rod separates from the fourth limiting block and swings until the second swing rod contacts the third limiting block; thereby realizing the swing of the first swing rod between the first limiting block and the second limiting block.

[0038] Further preferably, the driving component includes:

[0039] A slider, which is slidably connected to the floating body;

[0040] A first push block, which is fixedly connected to the slider;

[0041] A second push block, which is fixedly connected to the slider and is located on both sides of the first swing rod respectively with the first push block;

[0042] A driving part, which is drivingly connected to the slider and is used to drive the slider to slide.

[0043] With the above technical solution, the driving part drives the first slider to slide, the slider drives the first push block and the second push block to move, and the first push block and the second push block respectively drive the first swing rod to swing.

[0044] Further preferably, the driving part includes:

[0045] A fifth gear, which is rotatably connected to the slider and meshes with the rack;

[0046] A sixth gear, which is rotatably connected to the slider and meshes with the rack, and is located on both sides of the rack respectively with the fifth gear.

[0047] With the above technical solution, when the rack bends to one side along the path of the cave water body, the rack exerts a pulling force on the fifth gear, driving the fifth gear to move, and the fifth gear drives the slider to slide; when the rack bends to the other side along the path of the cave water body, the rack exerts a pulling force on the sixth gear, driving the sixth gear to move, and the sixth gear drives the slider to slide, thereby realizing the sliding of the slider towards the side where the rack bends.

[0048] Further preferably, the third gear is a helical gear and the fourth gear is a helical gear.

[0049] With the above technical solution, the helical gear has the advantages of smooth transmission and low noise.

[0050] Further preferably, the drive motor is a waterproof motor.

[0051] Further preferably, the roller is made of an elastic material.

[0052] By adopting the above technical solution, the vibration generated by the collision between the roller and the inner wall of the cave is reduced.

[0053] In summary, compared with the prior art, the beneficial effects of the present invention are as follows: When it is necessary to conduct environmental monitoring on the water body in a cave with a complex path, a rack is arranged along the path of the cave water body. The first driving device drives the first gear to rotate. Under the limiting action of the limiting device, the first gear drives the rack to move relative to the floating body, and the rack generates a pulling force on the floating body, so that the floating body moves along the length direction of the rack in the water body. At the same time, the water body monitoring device completes the monitoring of the water body environment. In the cave water body without satellite signals and with a complex path, the floating body drives the water body monitoring device to move along the correct path and complete the monitoring of the water body environment in the cave.

Detailed Description of the Invention

[0058] The following is a further detailed introduction to the present invention in combination with the attached Figure 1-2 drawings.

[0059] Chinese Patent Grant Publication No.: CN101776676B discloses a mobile in - water online comprehensive monitoring buoy. The working principle of the mobile in - water online comprehensive monitoring buoy of the present invention is as follows: The solar photovoltaic conversion panel converts solar energy into electrical energy, which is stored in the solar battery. Through the power management module, it provides energy in the form of direct current to the embedded computer, the power control drive board (including the directional electronic compass), the sensor signal conditioning and analog - to - digital conversion board, the GPS module, the GPRS module, the direction - adjusting functional thruster, the power - type thruster, etc. The data collected by the water body monitoring sensor and the micro - meteorological station can be processed by the embedded computer and transmitted to the remote monitoring system through the GPRS wireless communication method. When the buoy receives the position information of the buoy's target area from the remote monitoring system, the embedded computer can plan the corresponding movement trajectory by combining the current position information obtained by the GPS module and the orientation information (geographical north pole position) of the electronic compass, and then drive the corresponding thrusters to act through the power control drive board (including the directional electronic compass), and adjust the rotation speed of each thruster through the internal algorithm to achieve the self - control of the all - round movement of the buoy. All power consumption can be provided by the solar battery without an external power supply. In view of the related technology described above, the water body monitoring buoy plans the corresponding movement trajectory through the current position information obtained by the GPS module and the orientation information of the electronic compass to control the movement trajectory and direction of the water body monitoring buoy. However, the water body monitoring buoy can only be used in an environment with good satellite signals. When monitoring the cave water body environment, long - term monitoring of the cave water body at different time periods is required to obtain accurate data on the water body environment in the cave. Due to the extremely poor satellite signals in the cave, the water body monitoring buoy cannot move along the correct movement trajectory.

[0060] Based on the above technical problems, the applicant has the following technical solution concept:

[0061] By arranging racks in advance in the cave water body as paths, through the meshing of gears and racks, the rotation of the gears generates a pulling force, causing the floating body to drive the water body monitoring device to move along a fixed movement trajectory.

[0062] Based on the above concept, the applicant has proposed the technical solution of this application, which is specifically as follows:

[0063] A water body environment monitoring device, such as Figure 1 and Figure 2As shown in the figure, it includes: a floating body 1 with buoyancy for floating on the water body; a water body monitoring device 2 installed on the floating body 1 for monitoring the water body environment; a rack 3 passing through the floating body 1 for being arranged in the cave water body; a first gear 4 meshing with the rack 3 and rotatably connected to the floating body 1; a limiting device installed on the floating body 1 and in contact with the rack 3 for limiting the rack 3 so that the first gear 4 remains meshed with the rack 3; a first driving device installed on the floating body 1 and drivingly connected to the first gear 4 for driving the first gear 4 to rotate, thereby driving the floating body 1 to move along the length extension direction of the rack 3.

[0064] Before environmental detection of the cave water body with a complex path is required, the rack 3 needs to be fixed in the water body. As Figure 3 shown in the figure, one end of a fixing rod 23 can be fixedly connected to the rack 3, and the fixing rod 23 is fixed to the riverbed 24 at the bottom of the water body. When environmental detection of the cave water body with a complex path is required, the rack 3 is arranged along the path of the cave water body. The first driving device drives the first gear 4 to rotate. Under the limiting action of the limiting device, the first gear 4 drives the rack 3 to move relative to the floating body 1. The rack 3 generates a pulling force on the floating body 1, so that the floating body 1 moves in the water body along the length direction of the rack 3. At the same time, the water body monitoring device 2 completes the monitoring of the water body environment. In the cave water body without satellite signals, the floating body 1 drives the water body monitoring device 2 to move along the correct path to complete the monitoring of the water body environment in the cave.

[0065] Specifically, the rack 3 is a double-sided rack. The limiting device includes: a second gear 5 rotatably connected to the floating body 1 and located on both sides of the rack 3 respectively with the first gear 4. The second gear 5 cooperates with the first gear 4 to clamp the rack 3, thereby limiting the rack 3. At the same time, the second gear 5 can rotate to reduce the resistance of the rack 3 moving.

[0066] Specifically, the first driving device includes: a third gear 6 fixedly connected coaxially with the first gear 4; a fourth gear 7 fixedly connected coaxially with the second gear 5; a worm 8 rotatably connected to the floating body 1 and meshing with the third gear 6; a driving motor 9 installed on the floating body 1 and drivingly connected to the worm 8 for driving the worm 8 to rotate. The driving motor 9 drives the worm 8 to rotate. The worm 8 drives the third gear 6 to rotate. The third gear 6 drives the first gear 4 to rotate. At the same time, the third gear 6 drives the fourth gear 7 to rotate. The fourth gear 7 drives the second gear 5 to rotate, so that the first gear 4 and the second gear 5 rotate synchronously. The first gear 4 and the second gear 5 pull the rack 3 simultaneously to avoid wear on one side of the rack 3.

[0067] Specifically, it further includes: a first swing rod 10, with its end rotatably connected to the floating body 1; a roller 11, rotatably connected to the first swing rod 10, installed at one end of the first swing rod 10 away from the floating body 1, and used to contact the inner wall of the cave; a second driving device, installed on the floating body 1, drivingly connected to the first swing rod 10, and used to drive the first swing rod 10 to swing, so as to drive the roller 11 to swing. When a turning path appears in the cave water body, the length extension direction of the rack 3 also turns. The second driving device drives the first swing rod 10 to swing, and the first swing rod 10 drives the roller 11 to swing towards the inner side of the bending arc of the rack 3. The roller 11 contacts the inner wall of the cave, avoiding the collision between the floating body 1 and the inner wall of the cave, and prolonging the service life of the floating body 1.

[0068] Specifically, the second driving device includes: a second swing rod 12, with its end rotatably connected to the floating body 1; an elastic member 13, with one end connected to the first swing rod 10 and the other end connected to the second swing rod 12, and used to apply a force to the first swing rod 10 and the second swing rod 12, so that the first swing rod 10 and the second swing rod 12 approach each other; a first limiting block 14, fixedly connected to the floating body 1, in contact and cooperation with the first swing rod 10; a second limiting block 15, fixedly connected to the floating body 1, in contact and cooperation with the first swing rod 10, and respectively arranged on both sides of the first swing rod 10 with the first limiting block 14, and used to limit the swing amplitude of the first swing rod 10; a third limiting block 16, fixedly connected to the floating body 1, in contact and cooperation with the second swing rod 12; a fourth limiting block 17, fixedly connected to the floating body 1, in contact and cooperation with the second swing rod 12, and respectively arranged on both sides of the first swing rod 10 with the third limiting block 16, and used to limit the swing amplitude of the first swing rod 10; a pushing component, installed on the floating body 1, and used to push the first swing rod 10 to swing.

[0069] When the pushing component pushes the first swing rod 10 to swing, when the first swing rod 10 separates from the first limiting block 14, the elastic member 13 is stretched. When the first swing rod 10 contacts the second limiting block 15, under the elastic force of the elastic member 13, the second swing rod 12 separates from the third limiting block 16 and swings until the second swing rod 12 contacts the fourth limiting block 17; when the pushing component pushes the first swing rod 10 to swing, when the first swing rod 10 separates from the second limiting block 15, the elastic member 13 is stretched. When the first swing rod 10 contacts the first limiting block 14, under the elastic force of the elastic member 13, the second swing rod 12 separates from the fourth limiting block 17 and swings until the second swing rod 12 contacts the third limiting block 16; thus realizing the swing of the first swing rod 10 between the first limiting block 14 and the second limiting block 15.

[0070] Specifically, the pushing component includes: a slider 18, slidably connected to the floating body 1; a first pushing block 19, fixedly connected to the slider 18; a second pushing block 20, fixedly connected to the slider 18, and located on both sides of the first swing rod 10 respectively with the first pushing block 19; and a driving component, drivingly connected to the slider 18 for driving the slider 18 to slide. The driving component drives the first slider 18 to slide, the slider 18 drives the first pushing block 19 and the second pushing block 20 to move, and the first pushing block 19 and the second pushing block 20 respectively push the first swing rod 10 to swing.

[0071] Specifically, the driving component includes: a fifth gear 21, rotatably connected to the slider 18 and meshing with the rack 3; a sixth gear 22, rotatably connected to the slider 18 and meshing with the rack 3, and located on both sides of the rack 3 respectively with the fifth gear 21. When the rack 3 bends to one side along the path of the cave water body, the rack 3 exerts a pulling force on the fifth gear 21, pushing the fifth gear 21 to move, and the fifth gear 21 drives the slider 18 to slide; when the rack 3 bends to the other side along the path of the cave water body, the rack 3 exerts a pulling force on the sixth gear 22, pushing the sixth gear 22 to move, and the sixth gear 22 drives the slider 18 to slide, so as to realize the slider 18 sliding towards the bending side of the rack 3.

[0072] Specifically, the third gear 6 is a helical gear, and the fourth gear 7 is a helical gear. Helical gears have the advantages of smooth transmission and low noise.

[0073] Specifically, the driving motor 9 is a waterproof motor.

[0074] Specifically, the roller 11 is made of an elastic material. The vibration generated by the collision between the roller 11 and the cave inner wall is reduced.

[0075] Working principle and process

[0076] Please refer to Figures 1-3, the principle process of the present invention is described in detail as follows: Before environmental monitoring of the water body in a cave with a complex path, the rack 3 needs to be fixed in the water body. One end of the fixing rod 23 can be fixedly connected to the rack 3, and the fixing rod 23 is fixed to the riverbed 24 at the bottom of the water body. When environmental monitoring of the water body in a cave with a complex path is required, the rack 3 is arranged along the path of the cave water body. The driving motor 9 drives the worm 8 to rotate, the worm 8 drives the third gear 6 to rotate, the third gear 6 drives the first gear 4 to rotate, and at the same time the third gear 6 drives the fourth gear 7 to rotate, and the fourth gear 7 drives the second gear 5 to rotate, so that the first gear 4 and the second gear 5 rotate synchronously. The second gear 5 cooperates with the first gear 4 to clamp the rack 3, thereby limiting the rack 3. At the same time, the second gear 5 can rotate to reduce the resistance of the rack 3 to move. The first gear 4 drives the rack 3 to move relative to the floating body 1, and the rack 3 generates a pulling force on the floating body 1, so that the floating body 1 moves in the water body along the length direction of the rack 3. At the same time, the water body monitoring device 2 completes the monitoring of the water body environment.

[0077] When there is a turning path in the cave water body, the length extension direction of the rack 3 also turns. When the rack 3 bends towards one side along with the cave water body path, the rack 3 exerts a pulling force on the fifth gear 21, pushing the fifth gear 21 to move, and the fifth gear 21 drives the slider 18 to slide; when the rack 3 bends towards the other side along with the cave water body path, the rack 3 exerts a pulling force on the sixth gear 22, pushing the sixth gear 22 to move, and the sixth gear 22 drives the slider 18 to slide, so as to realize the slider 18 sliding towards the bending side of the rack 3. The slider 18 drives the first push block 19 and the second push block 20 to move. The first push block 19 and the second push block 20 respectively push the first swing rod 10 to swing. When the first swing rod 10 separates from the first limit block 14, the elastic member 13 is stretched. When the first swing rod 10 contacts the second limit block 15, under the action of the elastic force of the elastic member 13, the second swing rod 12 separates from the third limit block 16 and swings until the second swing rod 12 contacts the fourth limit block 17; when the rack 3 bends towards one side along with the cave water body path, the rack 3 exerts a pulling force on the fifth gear 21, pushing the fifth gear 21 to move, and the fifth gear 21 drives the slider 18 to slide; when the rack 3 bends towards the other side along with the cave water body path, the rack 3 exerts a pulling force on the sixth gear 22, pushing the sixth gear 22 to move, and the sixth gear 22 drives the slider 18 to slide, so as to realize the slider 18 sliding towards the bending side of the rack 3. The slider 18 drives the first push block 19 and the second push block 20 to move. The first push block 19 and the second push block 20 respectively push the first swing rod 10 to swing. When the first swing rod 10 separates from the second limit block 15, the elastic member 13 is stretched. When the first swing rod 10 contacts the first limit block 14, under the action of the elastic force of the elastic member 13, the second swing rod 12 separates from the fourth limit block 17 and swings until the second swing rod 12 contacts the third limit block 16; thus, the first swing rod 10 swings between the first limit block 14 and the second limit block 15. The first swing rod 10 drives the roller 11 to swing towards the inner side of the bending arc of the rack 3. The roller 11 contacts the cave inner wall, avoiding the collision between the floating body 1 and the cave inner wall and prolonging the service life of the floating body 1.

[0078] In the cave water body without satellite signals and with a complex path, the floating body 1 drives the water body monitoring device 2 to move along the correct path, completing the monitoring of the water body environment in the cave.
