Description

Technical Field

[0001] The invention belongs to the technical field of river water quality monitoring, in particular to a water quality monitoring device for river environment management. Background Art

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is the comprehensive indicators reflecting the water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand; the other is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organic pesticides.

[0003] In the process of water quality monitoring, it is necessary to collect water samples and analyze and test the samples in order to timely understand the water pollution situation. In the process of collecting samples, in addition to sampling at different locations in the river, since pollutants will be deposited near the riverbed, the pollution degree of water at different depths will also be different, so samples need to be collected from different depths.

[0004] A Chinese patent with application number CN202222893789.0 discloses a sampling device for water quality monitoring, which controls the winding and releasing of a pulling rope by driving a motor to rotate a reel, thereby sending a filter box into a water body at a specific depth, and then pumping water into a sample storage tank through a water pump to achieve the collection of water bodies at different depths. However, in this process, a large amount of river pollutants and impurities in the water body often adhere to the surface of the pulling rope after passing through the water. After the pulling rope is wound up by the reel, it is more difficult to clean the inner pulling rope. If the cleaning is not thorough, it is easy to cause corrosion to the pulling rope, affecting the service life and stability of the device.

DETAILED DESCRIPTION

[0035] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] like Figure 1-8 As shown, the present invention provides a water quality monitoring device for river environment management, comprising a hull 1, a winch assembly 2 is installed on one side of the top of the hull 1, a cleaning assembly 3 is installed on the other side of the top of the hull 1, a first driving assembly 4 is arranged on one side of the winch assembly 2 on the top of the hull 1, a second driving assembly 5 is installed on one side of the cleaning assembly 3 on the top of the hull 1, a transmission assembly 6 is arranged between the first driving assembly 4 and the second driving assembly 5, and a guide assembly 7 is also included;

[0038] The cleaning component 3 includes a fixed frame 301 fixedly arranged on the top of the hull 1. Two U-shaped frames 302 are slidably installed inside the fixed frame 301. Magnets 303 are fixedly arranged on the U-shaped frames 302, and the magnetic poles on the opposite sides of the magnets 303 on the two U-shaped frames 302 are opposite. Second rotating shafts 304 are rotatably installed inside the U-shaped frames 302. Cleaning sponges 305 are sleeved on the surfaces of the second rotating shafts 304. Under the action of the magnets 303, the two U-shaped frames 302 approach each other, so that the cleaning sponges 305 maintain sufficient pressure on the towing rope 204;

[0039] The first driving component 4 includes a worm 401 rotatably installed on the top of the hull 1 and a worm gear 402 fixedly connected to the first rotating shaft 203. The worm gear 402 is meshed with the worm 401. The first driving component 4 further includes a motor 403 fixedly installed on the top of the hull 1, and the output end of the motor 403 is in transmission connection with the worm 401. The motor 403 drives the worm 401 to rotate, the worm 401 drives the worm gear 402 to rotate, and the worm gear 402 drives the winding drum 202 to rotate, so as to wind or release the towing rope 204 through the winding drum 202;

[0040] The second driving component 5 includes a spline shaft 501 rotatably installed on the top of the hull 1 and coaxial with the worm 401. Two spline sleeves 502 are meshed on the outside of the spline shaft 501. A first bevel gear 503 is fixedly connected to the outside of the spline sleeve 502. An L-shaped movable plate 504 is also rotatably connected to the outside of the spline sleeve 502. A second bevel gear 505 is rotatably installed on the L-shaped movable plate 504. The second bevel gear 505 is meshed with the first bevel gear 503, and the two second bevel gears 505 are respectively fixedly connected to the two second rotating shafts 304. The spline shaft 501 drives the spline sleeve 502 to rotate, the spline sleeve 502 drives the first bevel gear 503 fixedly connected thereto to rotate, the first bevel gear 503 drives the second bevel gear 505 meshed therewith to rotate, and the two second bevel gears 505 respectively drive the two second rotating shafts 304 to rotate in opposite directions, so as to drive the cleaning sponges 305 to rotate by the second rotating shafts 304 to clean the towing rope 204 and the sampling cylinder 205;

[0041] The transmission assembly 6 includes a third bevel gear 601, a fourth bevel gear 602 and a fifth bevel gear 603. The third bevel gear 601 is fixedly connected to one end of the worm 401, and the fourth bevel gear 602 is rotatably mounted on the outer side of the spline shaft 501. The fifth bevel gear 603 is rotatably mounted on the top of the hull 1 and is located between the third bevel gear 601 and the fourth bevel gear 602. The third bevel gear 601 and the fourth bevel gear 602 are both meshed and connected with the fifth bevel gear 603. The transmission assembly 6 also includes two ratchet wheels 604 symmetrically arranged on the surface of the spline shaft 501 between the third bevel gear 601 and the fourth bevel gear 602, and the ratchet teeth on the surfaces of the two ratchet wheels 604 are in opposite directions. Ratchet pawls 605 that can cooperate with the ratchet wheels 604 are respectively installed in an array around the two ratchet wheels 604 on the opposite sides of the third bevel gear 601 and the fourth bevel gear 602. The worm 40 When the third bevel gear 601 is driven to rotate forwardly, the pawl 605 provided on the third bevel gear 601 is engaged with one of the ratchet wheels 604 on the spline shaft 501, so that the third bevel gear 601 can drive the spline shaft 501 to rotate in the same direction. During this process, the third bevel gear 601 drives the fourth bevel gear 602 to rotate in the opposite direction through the fifth bevel gear 603. However, since the ratchet teeth on the surface of the other ratchet wheel 604 are in the opposite direction, the fourth bevel gear 602 will not affect the forward rotation of the spline shaft 501. When the worm 401 drives the third bevel gear 601 to rotate in the reverse direction, the fourth bevel gear 602 is driven to rotate forwardly through the fifth bevel gear 603. At this time, the pawl 605 provided on the fourth bevel gear 602 is engaged with the other ratchet wheel 604, so that the spline shaft 501 is driven to continue to rotate forwardly through the fourth bevel gear 602.

[0042] As a preferred technical solution of the present invention, a movable groove 8 for two second rotating shafts 304 to pass through and connected to the second bevel gear 505 is provided on one side of the fixed frame 301 close to the spline shaft 501, and the movable groove 8 provides space for the two second rotating shafts 304 to move.

[0043] As a preferred technical solution of the present invention, the guide assembly 7 includes a fixing frame 701 arranged on the top of the fixing frame 301 and a fixing plate 705 arranged on the shaped frame 302 near the position of the hoisting assembly 2;

[0044] A limit plate 702 is fixedly disposed on the top of the fixing frame 701, a guide wheel 703 is installed on the top of the limit plate 702, and a first through hole 704 is also opened on the limit plate 702;

[0045] The fixed plate 705 is arranged on the side of the U-shaped frame 302 close to the hoisting assembly 2. Two sliding rods 706 are symmetrically installed at the top of the fixed plate 705. A moving plate 707 is slidably installed between the two sliding rods 706 at the top of the fixed plate 705. The two ends of the moving plate 707 are respectively slidably connected to the two sliding rods 706. A second through hole 708 is formed in the moving plate 707. A spring 709 is sleeved on the surface of the sliding rod 706, and the spring 709 is located between the moving plate 707 and the hoisting assembly 2. The moving plate 707 is kept on the side of the top of the fixed plate 705 away from the hoisting assembly 2 by the spring 709.

[0046] As a preferred technical solution of the present invention, the guiding assembly 7 further includes a fixing strip 710 arranged below the cleaning sponge 305 at the bottom of the U-shaped frame 302. A V-shaped frame 711 is arranged on the side of the fixing strip 710 close to the other U-shaped frame 302. The towing rope 204 passes through the second through hole 708, the guiding wheel 703, the first through hole 704, between the two cleaning sponges 305, and between the two V-shaped frames 711 in sequence. When not wound onto the sampling cylinder 205, the area between the two V-shaped frames 711 is slightly larger than the size of the limiting block 9, so that the towing rope 204 can be limited to prevent the towing rope 204 from shifting. After the distance between the two U-shaped frames 302 changes, the size of the area formed between the two V-shaped frames 711 will also increase accordingly, facilitating the passage of the sampling cylinder 205.

[0047] As a preferred technical solution of the present invention, a limiting block 9 is arranged on the surface of the towing rope 204 near the sampling cylinder 205. The outer diameter of the limiting block 9 is smaller than the inner diameter of the first through hole 704 and larger than the inner diameter of the second through hole 708. The limiting block 9 can pass through the inside of the first through hole 704, but cannot pass through the second through hole 708. After the winding drum 202 winds the towing rope 204 to move the limiting block 9 to the position of the second through hole 708, continuing to wind the towing rope 204 can pull the moving plate 707 to move.

[0048] As a preferred technical solution of the present invention, a fixed sleeve 10 is fixedly arranged at the top of the fixed frame 301. A gear 11 is rotatably installed inside the fixed sleeve 10. Rack bars 12 are installed above and below the gear 11 inside the fixed sleeve 10. The two rack bars 12 are respectively fixedly connected to the two U-shaped frames 302, and both rack bars 12 are meshed with the gear 11. Through the arrangement of the two rack bars 12, when the U-shaped frame 302 near the hoisting assembly 2 moves, it will drive the rack bar 12 connected thereto to move. When the rack bar 12 moves, it will drive the gear 11 to rotate, so that the other rack bar 12 moves in the opposite direction, thereby achieving the synchronous movement of the two U-shaped frames 302 in opposite directions to change the radius of the two second rotating shafts 304, so as to adapt to the size of the towing rope 204 or the sampling cylinder 205.

[0049] As a preferred technical solution of the present invention, the cleaning component 3 also includes a scraper 13 arranged on the inner side of the shaped frame 302, and one side of the scraper 13 is in contact with the cleaning sponge 305. During the rotation of the cleaning sponge 305, the scraper 13 can scrape off the debris on the surface of the cleaning sponge 305 to keep the surface of the cleaning sponge 305 clean.

[0050] As a preferred technical solution of the present invention, the overall center of gravity of the sampling barrel 205 is biased downward, and a guide strip 14 is provided on the outside of the sampling barrel 205. The guide strip 14 is used to improve the stability of the sampling barrel 205 during the sinking process. The third through hole 15 is provided at the bottom and the top of the sampling barrel 205, and a one-way valve is installed on the inner side of the third through hole 15. The one-way valve makes the third through hole 15 open only in one direction. During the sinking process of the sampling barrel 205, the water flow exerts an upward force on the one-way valve from below to prompt the one-way valve to open. At this time, the third through holes 15 at the bottom and top of the sampling barrel 205 form a passage, and the water flows into the bottom of the sampling barrel 205 and is discharged from the top of the sampling barrel 205 in time. After reaching the target depth, the traction rope 204 pulls the sampling barrel 205 upward. During the upward traction of the sampling barrel 205, the water flow exerts a force on the one-way valve from above, and the one-way valve cannot be opened, so that the water body at the target depth is preserved inside the sampling barrel 205.

[0051] Specific working principle:

[0052] When the device is in use, the hull 1 is first controlled to move to the target area of ​​the river. The control of the hull 1 can be achieved by conventional technical means such as remote control, which will not be described in detail here. When the hull 1 moves to the target area, the motor 403 is started, and the motor 403 drives the worm 401 to rotate, and the worm 401 drives the worm wheel 402 to rotate, so that the winding drum 202 releases the traction rope 204, and the sampling tube 205 sinks to the target depth under its own gravity. During the sinking process, the water flow opens the one-way valve at the bottom of the sampling tube 205 from the bottom of the sampling tube 205, and the sampling tube 205 is taken out from the sampling tube 205. 05 opens the one-way valve at the top of the sampling cylinder 205, so that the water at the non-target depth is discharged from the top of the sampling cylinder 205 in time. After reaching the target depth, the water at the target depth enters the sampling cylinder 205, and the motor 403 drives the winding drum 202 to rotate the winding traction rope 204 in the opposite direction to make the sampling cylinder 205 rise. In this process, the one-way valve is closed under the action of water pressure, so that the water at the target depth flows out of the sampling cylinder 205, and at the same time, it can prevent the water at the non-target depth from entering the sampling cylinder 205, and complete the collection of water samples at the target depth;

[0053] When the winding drum 202 winds up the traction rope 204, the two yokes 302 approach each other and clamp the traction rope 204 under the action of the two magnets 303. At the same time, the worm 401 drives the spline shaft 501 to rotate through the transmission mechanism. The spline shaft 501 drives the first bevel gear 503 to rotate through the spline sleeve 502. The first bevel gear 503 drives the two second rotating shafts 304 to rotate in opposite directions through the second bevel gear 505. The second rotating shaft 304 rotates and drives the cleaning sponge 305 to rotate. 305 cleans the surface of the traction rope 204. When the reel 202 reels the traction rope 204 to the position where the sampling tube 205 is close to the bottom of the V-shaped frame 302, the limit block 9 passes through the two V-shaped frames 711, the two cleaning sponges 305, the first through hole 704, and the surface of the guide wheel 703 and moves to the second through hole 708 in sequence. Since the second through hole 708 is smaller than the size of the limit block 9, the limit block 9 cannot pass through the second through hole 708. The reel 202 continues to reel the traction rope 204, which will pull the moving The movable plate 707 moves, and at the same time, under the action of the spring 709 set on the surface of the slide bar 706, the movable plate 707 is kept at the top of the fixed plate 705 at a position away from the winding drum 202. Therefore, during the winding process, the limit block 9 will drive the shaped frame 302 to approach the winding drum 202. During the movement of the shaped frame 302, one of the racks 12 is driven to move, and the rack 12 drives the other rack 12 to move in the opposite direction through the gear 11, so that the other shaped frame 302 moves to a position away from the winding drum 202, thereby making As the distance between the two second rotating shafts 304 increases, the two V-shaped frames 302 move away from each other, which will simultaneously drive the two V-shaped frames 711 to move in opposite directions, thereby increasing the size of the area formed between the two V-shaped frames 711, making it easier for the sampling barrel 205 to pass between the two V-shaped frames 711. At the same time, as the distance between the two second rotating shafts 304 increases, the sampling barrel 205 can also pass between the two rotating shafts. During this process, the two cleaning sponges 305 continue to rotate, making it easier to clean the surface of the sampling barrel 205.

[0054] By setting the transmission component 6, no matter in which direction the worm 401 drives the winding drum 202 to rotate through the worm wheel 402, the rotation direction of the spline shaft 501 will only rotate in one direction. At the same time, due to the deceleration characteristics between the worm 401 and the worm wheel 402, the rotation speed of the cleaning sponge 305 is higher than the rotation speed of the winding drum 202. Therefore, in the process of the winding drum 202 releasing the traction rope 204, the two cleaning sponges 305 rotate while the traction rope 204 between the winding drum 202 and the cleaning sponge 305 is kept in a taut state. Similarly, in the process of the winding drum 202 winding up the traction rope 204, since the cleaning sponge 305 still keeps rotating in the same direction, the traction rope 204 between the cleaning sponge 305 and the winding drum 202 is still kept in a taut state, thereby improving the tightness of the traction rope 204 on the surface of the winding drum 202 and preventing the traction rope 204 from being entangled and knotted.
