Description

Technical Field

[0001] The present invention relates to the technical field of water level sensors, and particularly to an adaptive high-precision water level monitoring sensor and an installation method thereof. Background Technique

[0002] A radar water level gauge is an electronic device that uses electromagnetic waves to detect targets. It emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the water flow to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, height, etc. For example, the existing product AD110C / AD110D high-frequency radar level gauge has the principle that a microwave pulse of micro power is emitted from the radar antenna, propagates in space at the speed of light, is reflected by the measured object and received by the radar. The time difference between the emission and reception of the pulse signal is proportional to the distance from the radar antenna to the measured object. The propagation speed of the electromagnetic wave signal in space is the speed of light. Usually, when measuring the distance, the time difference between the emitted pulse and the received pulse is extremely short, only on the order of nanoseconds, and it is very difficult for conventional techniques to accurately measure this time.

[0003] Existing radar water level gauges have the characteristics of convenient installation and long service life. However, during normal use, there are also some factors that affect the detection accuracy of the radar water level gauge. For example, the turbidity of the water body will affect the penetration and reflection of the radar signal. High turbidity will absorb or scatter the radar wave, reducing the signal intensity. Suspended solid content: A large amount of suspended solids will also affect the reception and processing of the radar signal, thereby affecting the measurement accuracy. For floating objects on the water surface that will affect the radar light wave, it is difficult to directly deal with them by manual cleaning. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an adaptive high-precision water level monitoring sensor and an installation method thereof to solve the problems raised in the above background technology. The structure of the present invention is novel. The water level is measured jointly by the radar water level sensor and the float assembly, improving the detection accuracy. At the same time, the float assembly cooperates with the drive assembly and can move around the periphery of the radar water level sensor, concentrating the surrounding floating objects near the storage assembly and cleaning them through the storage assembly, keeping the water surface free of floating objects that affect the radar light wave and improving the detection accuracy.

[0008] Further, scraping frames are fixed at the positions corresponding to the filter screen passing through on the floating upper plate and the sinking plate. The two sides of the filter screen are in sliding contact with the scraping frames. A vertical plate is fixed at the movable end of the filter screen. First electric push rods are fixed on the outer walls of the two sides of the scraping frames, and the extending ends of the first electric push rods are in pressing contact with the vertical plate. An insertion frame is fixed on the surface of the winding shaft of the other set of the floating component. The vertical plate can be inserted into the insertion frame.

[0009] Further, slots are opened on both sides of the vertical plate. Insertion plates are slidably inserted on both sides of the insertion frame, and the insertion plates are slidably inserted into the slots. A bidirectional electric push rod is fixed at the top of the insertion frame, and the extending end of the bidirectional electric push rod is fixedly connected to the insertion plate.

[0010] Further, the storage component further includes a collection groove. A collection groove is formed on the middle surface of the collection frame, and the collection groove is communicated with the inside of the collection box. A sewage discharge pipe is fixed to the back of the collection box. A baffle is covered on the surface of the collection groove, and storage grooves are formed on both sides of the collection frame corresponding to the baffle. A sliding groove is formed on the surface of the collection frame on one side of the baffle, and a convex block is slidably connected inside the sliding groove.

[0011] Further, a second electric push rod is fixed on the surface of the vertical rod, and the extending end of the second electric push rod is fixedly connected to the top of the storage box.

[0012] Further, the driving component further includes a first gear. A first gear is fixed on the connecting plate at the uppermost end of the fixing frame. A first driven gear is meshed on one side of the first gear. A second driven gear is fixed to the bottom of the first driven gear. Both the first driven gear and the second driven gear are rotatably installed on the fixing frame. A second gear is fixed on the connecting plate at the lower end of the fixing frame, and a transmission gear is meshed between the second gear and the second driven gear.

[0013] Further, a transmission belt is installed at the output end of the motor. A pulley at the other end of the transmission belt is fixed with a shaft rod. A rotating ring is rotatably installed on the surface of the mounting disc, and the shaft rod is fixedly passed through the rotating ring. A brush plate is fixed to the bottom of the shaft rod, and the brush plate is in sliding contact with the inner and outer walls of the transmitting cover of the radar water level sensor.

[0014] An installation method for an adaptive high-precision water level monitoring sensor, the installation method includes the following steps: (1) Fix the mounting base on the bank of the measured water area, select a relatively flat area, and vertically correct the mounting base and the vertical rod through a level; (2) Fix the mounting disc of the radar water level sensor to the front end of the cross plate, and keep the radar transmitting end perpendicular to the water surface; (3) Install the storage component on the bank near the mounting base, and connect the sewage discharge pipe to the external sewage treatment equipment; (4) Install the float component on the top of the radar water level sensor and unfold it when it is necessary to clean the floating objects on the water surface.

[0015] The beneficial effects of the present invention: In the present invention, a connecting plate at the lower end is rotated by a motor. The second gear meshes with the transmission gear, and the transmission gear meshes with the second driven gear. The first driven gear and the second driven gear rotate coaxially. The first driven gear meshes with the first gear to transmit kinetic energy to the connecting plate at the upper end, causing the two connecting plates to rotate synchronously and in opposite directions. When not in use, the two floating component groups can be moved to the rear end to avoid interfering with the detection of the radar water level sensor. When in use, the two floating component groups are rotated to the front end. After the two take-up reels are connected through the filter screen and then return, during this process, the unfolding of the filter screen will gather the floating impurities in the water area around the radar water level sensor and move them towards the side of the storage component.

[0016] In the present invention, through the transmission of the transmission belt, the shaft rod is driven to rotate along the shaft collar, so that the brush plate slides along the inner and outer walls of the transmitting cover of the radar water level sensor to clean the dust on its surface. The brush plate is made of a material that does not interfere with the emission of radar light waves.

[0017] In the present invention, due to the elastic force of the return spring, the convex block slides to the outermost side of the chute, and at this time, the baffle blocks the storage groove. When the floating component group rotates near the collection frame, the take-up reel on one side of the insertion frame will contact the convex block, thereby pushing the baffle into the storage groove to open the collection groove. The floating objects are pumped out through the pump body connected to the rear end of the sewage pipe. The sewage pipe is a flexible pipe and can adjust its position. The second electric push rod can lift and adjust the position of the entire storage component to keep it corresponding to the positions of the upper floating plate and the lower sinking plate, so that the upper floating plate and the lower sinking plate can slide into contact with the top and bottom of the collection frame, and the storage shaft extends into the collection frame without moving interference.

[0018] In the present invention, when the two sliding rods approach, the first electric push rod pushes the vertical plate towards the insertion frame. After the vertical plate is inserted into the insertion frame, the bidirectional electric push rod drives the two insertion plates to insert into the slots of the vertical plate, thereby realizing the locking connection between the insertion frame and the vertical plate. During the subsequent rotation of the two floating component groups, the filter screen is gradually opened and wraps the surrounding water area. When approaching the storage component, the filter screen will contract to gather and collect the floating objects.

[0019] Compared with the prior art, in the present invention, the water level is measured jointly by the radar water level sensor and the floating component group, improving the detection accuracy. At the same time, the floating component group cooperates with the drive component and can move around the periphery of the radar water level sensor, concentrating the surrounding floating objects near the storage component and cleaning them through the storage component, keeping the water surface free of floating objects that affect radar light waves and improving the detection accuracy.

The winding shaft 37 slides along the inside of the collection frame 41. When using the device, fix the mounting base 1 on the bank of the measured water area, vertically correct the mounting base 1 and the vertical rod 11 with a level, then fix the mounting plate 21 of the radar water level sensor 2 to the front end of the cross plate 13, adjust to an appropriate height and then detect the water level. Through the cooperation of the float component 3 and the driving component 5, the floating objects in the water area around the radar water level sensor 2 are collected and gathered, and are collected and discharged through the storage component 4 to avoid affecting the detection accuracy of the radar water level sensor 2.

[0025] In this embodiment, a photovoltaic panel 14 is rotatably installed at the outer end of the sliding seat 12. Locking bolts 16 are inserted on both the rotation installation position of the photovoltaic panel 14 and the surface of the sliding seat 12. The sliding seat 12 and the photovoltaic panel 14 are fixedly installed through the locking bolts 16. A towing rope 15 is fixed to the top of the vertical rod 11, and the other end of the towing rope 15 is fixedly connected to the outermost end of the fixed frame 17. The photovoltaic panel 14 provides power for the device. Through the fixation of the sliding seat 12 and the locking bolts 16, it is convenient to adjust the installation position of the radar water level sensor 2. The towing rope 15 maintains the stability of the front end of the fixed frame 17 and does not tilt.

[0026] In this embodiment, the float assembly 3 further includes a fixing plate 33. The fixing plate 33 is fixed on the top surface of the sliding rod 32, and a suspension rope 34 is fixed to the bottom of the fixing plate 33. The other end of the suspension rope 34 is fixedly connected to the upper floating plate 35. Scraping frames 39 are fixed at the positions where the upper floating plate 35 and the lower sinking plate 36 correspond to the penetration of the filter screen 38. The two sides of the filter screen 38 are in sliding contact with the scraping frames 39. A vertical plate 310 is fixed to the movable end of the filter screen 38. First electric push rods 312 are fixed on the outer walls of both sides of the scraping frame 39, and the extending ends of the first electric push rods 312 are in pressing contact with the vertical plate 310. An insertion frame 313 is fixed on the surface of the other take-up reel 37 of the float assembly 3. The vertical plate 310 can be inserted into the interior of the insertion frame 313. Slots 311 are formed on both sides of the vertical plate 310. Insertion plates 314 are slidably inserted into both sides of the insertion frame 313, and the insertion plates 314 are slidably inserted into the slots 311. A bidirectional electric push rod 315 is fixed to the top of the insertion frame 313, and the extending end of the bidirectional electric push rod 315 is fixedly connected to the insertion plate 314. An infrared sensor can be installed on the top of the sliding rod 32 to measure the lifting height of the upper floating plate 35. The upper floating plate 35 and the lower sinking plate 36 are integrated. The upper floating plate 35 floats on the water surface. The change in the distance measured by the upper floating plate 35 can be compared with the water level change measured by the radar water level sensor 2. When there is a large error, an electric signal causes the drive assembly 5 to be activated, and the float assembly 3 cleans the surrounding water area. When the two sliding rods 32 approach, the first electric push rod 312 pushes the vertical plate 310 to move towards the insertion frame 313. After the vertical plate 310 is inserted into the insertion frame 313, the bidirectional electric push rod 315 drives the two insertion plates 314 to be inserted into the slots 311 of the vertical plate 310, thereby realizing the locking connection between the insertion frame 313 and the vertical plate 310. During the subsequent rotation of the two groups of float assemblies 3, the filter screen 38 is gradually opened and wraps the surrounding water area. When approaching the storage assembly 4, the filter screen 38 will contract again to gather and collect the floating objects.

[0027] In this embodiment, the storage assembly 4 further includes a collection groove 43. The collection groove 43 is formed on the middle surface of the collection frame 41, and the collection groove 43 is communicated with the inside of the collection box 47. A sewage discharge pipe 48 is fixed to the back of the collection box 47. A baffle 42 covers the surface of the collection groove 43, and the collection frame 41 is provided with storage grooves on both sides corresponding to the baffle 42. A sliding groove 46 is formed on one surface of the collection frame 41 on the side of the baffle 42, and a convex block 44 is slidably connected inside the sliding groove 46. The convex block 44 is fixedly connected to the baffle 42. A return spring 45 is fixed between the convex block 44 and the sliding groove 46. A second electric push rod 49 is fixed on the surface of the vertical rod 11, and the extending end of the second electric push rod 49 is fixedly connected to the top of the storage box. In the initial state, due to the elastic force of the return spring 45, the convex block 44 slides to the outermost side of the sliding groove 46, and at this time, the baffle 42 blocks the storage groove. When the float assembly 3 rotates to the vicinity of the collection frame 41, the winding shaft 37 on one side of the insertion frame 313 will contact the convex block 44, thereby pushing the baffle 42 into the storage groove and opening the collection groove 43. The floating objects are pumped out through the sewage discharge pipe 48 with a pump body connected to the rear end. The sewage discharge pipe 48 is a flexible pipe and can adjust its position. The second electric push rod 49 can lift and adjust the position of the entire storage assembly 4 to keep it corresponding to the positions of the floating plate 35 and the sinking plate 36, so that the floating plate 35 and the sinking plate can slide into contact with the top and bottom of the collection frame 41, and the storage shaft extending into the collection frame 41 will not interfere with the movement.

[0028] In this embodiment, the driving component 5 further includes a first gear 56. The first gear 56 is fixed on the surface of the connecting plate 31 at the uppermost end of the fixing frame 17. A first driven gear 57 is meshed and connected to one side of the first gear 56. A second driven gear 58 is fixed at the bottom of the first driven gear 57. Both the first driven gear 57 and the second driven gear 58 are rotatably installed on the fixing frame 17. A second gear 59 is fixed on the surface of the connecting plate 31 at the lower end of the fixing frame 17. A transmission gear 510 is meshed and connected between the second gear 59 and the second driven gear 58. A transmission belt 52 is installed at the output end of the motor 51. The other pulley of the transmission belt 52 is fixed with a shaft rod 53. A rotating ring 54 is rotatably installed on the surface of the mounting disc 21, and the shaft rod 53 is fixedly passed through the rotating ring 54. A brush plate 55 is fixed at the bottom of the shaft rod 53. The brush plate 55 is in sliding contact with the inner and outer walls of the transmitting cover of the radar water level sensor 2. The motor 51 drives the connecting plate 31 at the lower end to rotate. The second gear 59 is meshed with the transmission gear 510, and the transmission gear 510 is meshed with the second driven gear 58. The first driven gear 57 and the second driven gear 58 rotate coaxially. The first driven gear 57 is meshed with the first gear 56 to transmit kinetic energy to the connecting plate 31 at the upper end, so that the two connecting plates 31 rotate synchronously and in opposite directions. When not in use, the two sets of float assemblies 3 can be moved to the rear end to avoid interfering with the detection of the radar water level sensor 2. When in use, the two sets of float assemblies 3 are rotated to the front end. After the two take-up reels 37 are connected through the filter screen 38, then return. During this process, the unfolding of the filter screen 38 will gather the floating impurities in the water area around the radar water level sensor 2 and move them towards the storage assembly 4. At the same time, the rotation of the motor 51 drives the shaft rod 53 to rotate along the shaft ring through the transmission of the transmission belt 52, so that the brush plate 55 slides along the inner and outer walls of the transmitting cover of the radar water level sensor 2 to clean the dust on its surface. The brush plate 55 is made of a material that does not interfere with the emission of radar light waves.

[0029] When using the device, fix the mounting base 1 on the bank of the measured water area. Vertically correct the mounting base 1 and the vertical rod 11 with a level. Then fixedly connect the mounting plate 21 of the radar water level sensor 2 to the front end of the cross plate 13. After adjusting the appropriate height, detect the water level. Install an infrared sensor on the top of the sliding rod 32 to measure the lifting height of the floating plate 35. The floating plate 35 and the sinking plate 36 are integrated. The floating plate 35 floats on the water surface. The change in the distance measured by the floating plate 35 can be compared with the change in the water level measured by the radar water level sensor 2. When there is a large error, the electric signal causes the drive assembly 5 to start, and the float assembly 3 cleans the surrounding water area. When the two sliding rods 32 approach, the first electric push rod 312 pushes the vertical plate 310 towards the insertion frame 313. After the vertical plate 310 is inserted into the insertion frame 313, the bidirectional electric push rod 315 drives the two insertion plates 314 to insert into the slot 311 of the vertical plate 310, thereby realizing the locking connection between the insertion frame 313 and the vertical plate 310. During the subsequent rotation of the two float assemblies 3, the filter screen 38 is gradually opened and wraps the surrounding water area. When approaching the storage assembly 4, the filter screen 38 will contract again to gather and collect the floating objects. The motor 51 drives the connecting plate 31 at the lower end to rotate. The second gear 59 meshes with the transmission gear 510, and the transmission gear 510 meshes with the second driven gear 58. The first driven gear 57 and the second driven gear 58 rotate coaxially. The first driven gear 57 meshes with the first gear 56 to transmit kinetic energy to the connecting plate 31 at the upper end, causing the two connecting plates 31 to rotate synchronously and in opposite directions. When not in use, the two float assemblies 3 can be moved to the rear end to avoid interfering with the detection of the radar water level sensor 2. When in use, rotate the two float assemblies 3 to the front end. After the two winding shafts 37 are connected through the filter screen 38, then return. During this process, the unfolding of the filter screen 38 will gather the floating impurities in the water area around the radar water level sensor 2 and move them towards the storage assembly 4 side. At the same time, the rotation of the motor 51 drives the shaft rod 53 to rotate along the shaft collar through the transmission of the transmission belt 52, causing the brush plate 55 to slide along the inner and outer walls of the transmitting cover of the radar water level sensor 2 to clean the dust on its surface. In the initial state, due to the elasticity of the return spring 45, the convex block 44 slides to the outermost side of the chute 46, and the baffle 42 blocks the storage groove at this time. When the float assembly 3 rotates to near the collection frame 41, the winding shaft 37 on one side of the insertion frame 313 will contact the convex block 44, thereby pushing the baffle 42 into the storage groove and opening the collection groove 43. Connect the rear end of the sewage discharge pipe 48 to a pump body to pump out the floating objects. The sewage discharge pipe 48 is a flexible pipe and can adjust its position. The second electric push rod 49 can lift and adjust the position of the entire storage assembly 4 to keep it corresponding to the positions of the floating plate 35 and the sinking plate 36, so that the floating plate 35 and the sinking plate 36 can slide into contact with the top and bottom of the collection frame 41, and the storage shaft extends into the collection frame 41 without moving interference, avoiding affecting the detection accuracy of the radar water level sensor 2.
