A reel for synchronously winding two cables is provided inside the storage ring. A sunken tube with a lateral groove is sleeved on the outside of the connecting cable, and a card block is provided on the outside of the driving steel cable that is staggered and engaged with the groove.

[0007] The waterproof central control box is equipped with a drive motor and two sets of electromagnetic telescopic parts, including:

[0008] The drive motor selectively drives the receiving ring to perform 360° limited rotation or drives the reel to retract and release the cable through the expansion and contraction switching of the electromagnetic telescopic part;

[0009] When the electromagnetic telescopic member is extended, its telescopic portion locks the rotational freedom of the drum.

[0010] Preferably, the shaft rod is externally sleeved with a shaft disc mounted via a bearing, the axis of the reel passes through the eccentric portion of the shaft disc and extends into the waterproof central control box, and the axis end of the reel is sleeved with a retractable gear.

[0011] Preferably, a lifting bracket is installed between the telescopic parts of the two electromagnetic telescopic members, a locking ring is installed below the end of the lifting bracket, and a switching disk is coaxially connected between the lifting bracket and the locking ring through a bearing;

[0012] The lock ring and the switching disk move synchronously along the axial direction with the telescopic part of the electromagnetic telescopic component, and the inner wall of the lock ring is provided with a lock groove that meshes with the gear teeth on the surface of the retractable gear.

[0013] Preferably, the outer periphery of the switching disk is evenly distributed with driving teeth and grooves, and the output shaft of the driving motor is sleeved with a driving gear meshing with the driving teeth and grooves;

[0014] The tooth length of the driving gear is consistent with the movable length of the switching disk along with the telescopic portion of the electromagnetic telescopic member.

[0015] Preferably, one end of the shaft located at the top of the shaft disc is sleeved with a steering gear, and the steering gear and the retracting gear are staggered in an up-and-down manner;

[0016] An upper transmission tooth groove meshing with the steering gear is provided on the inner side of the upper end portion of the switching disk, and a lower transmission tooth groove meshing with the retracting gear is provided on the inner side of the lower end portion of the switching disk.

[0017] Preferably, the receiving ring is provided with two sets of interlocking frames at positions corresponding to the support tube, and the two interlocking frames are connected by a separation plate;

[0018] The connecting cables and the driving steel cables are distributed at the front and rear parts of the separation plate, and the two interlocking frames are located at the bottom of one side of the driving steel cables and are connected to auxiliary rollers through a rotating shaft.

[0019] Preferably, the facing surfaces of the two engaging frames are each provided with an inclined groove corresponding to the driving steel cable, and the two inclined grooves are arranged in an inclined manner from top to bottom and facing each other;

[0024] 1. This solution is controlled by a linkage cable group consisting of parallel connecting cables and drive cables. The monitoring depth of the monitoring device can be adjusted by synchronous retraction and extension. The drive cable can also be pulled alone to tilt the immersed tube to form a monitoring offset angle, allowing the monitoring device to move in a circumferential fan-shaped range along the buoy axis, thereby expanding the monitoring range.

[0025] 2. The waterproof central control box features a dual-mode switching mechanism driven by an electromagnetic telescopic element. A lifting bracket controls the meshing state of the switching disc with the steering gear and retraction gear, enabling independent control of monitoring azimuth adjustment and cable retraction. The interlocking frame and chute mechanism, combined with the traction rope, precisely control the displacement of the drive cable through the lifting block when the electromagnetic telescopic element is activated. Meanwhile, a separation plate and auxiliary rollers ensure orderly separation and interlocking of the cables during retraction and extension. This eliminates the need for multiple motors to drive each, reducing internal redundancy, lowering costs, and lowering overall weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "up", "down", "left", "right", etc. indicate directions or positional relationships, they are based on the directions or positional relationships shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0043] The implementation of the present invention is described in detail below with reference to specific embodiments.

[0044] This application aims to solve the problem that traditional floating water quality monitors can usually only stay in shallow water bodies, have a limited monitoring range, and usually require multiple devices to be configured when conducting large-scale water environment monitoring, resulting in high monitoring costs.

[0045] In this embodiment:

[0046] Reference Figure 1-Figure 2 As shown, a preferred embodiment of the present invention is provided.

[0047] A floating water quality monitor of this embodiment includes a float 1, a storage box 2 fixed to the top of the float 1, a waterproof central control box 3 installed above the storage box 2, and a monitoring component 4 provided below the float 1. The monitoring component 4 is a sensor encapsulated in a stainless steel filter. The stainless steel filter can prevent floating objects and organisms in the water from damaging the sensor, and can also suppress the water hammer effect in waters with high flow rates. The sensor types can be freely matched, including monitoring pH, EC, dissolved oxygen, turbidity, residual chlorine, COD, chlorophyll, blue-green algae, ammonia nitrogen, suspended solids, ORP, ions, etc., which are existing technologies well known to those skilled in the art and will not be described in detail in this solution.

[0048] The outer ring of the waterproof central control box 3 is provided with solar panels 12, which charge the power supply inside the waterproof central control box 3 to ensure that the monitor can be used outdoors for a long time; fixed earrings 11 are provided around the top of the float 1, which can be used to fix the float 1, and counterweights can also be added through the fixed earrings 11 to lower the center of gravity of the float 1 and avoid rollover.

[0049] exist Figure 5 In the embodiment, a support tube 23 passing through the float 1 is coaxially fixed to the bottom of the storage box 2, and a linkage cable group is arranged in the support tube 23, which includes a connecting cable 24 and a driving steel cable 26 arranged in parallel. The bottom ends of the two cables are connected to the monitoring part 4 and control its lifting. A hollow shaft 22 which can rotate around its axis is provided inside the storage box 2, and a storage ring 211 is provided at the bottom end of the shaft 22. A drum 25 for synchronously winding the two cables is provided in the storage ring 211. A sunken tube 241 with a lateral pulling groove 242 is sleeved on the outside of the connecting cable 24, and a card block 261 which is staggered and embedded with the pulling groove 242 is provided on the outside of the driving steel cable 26. The driving steel cable 26 and the connecting cable 24 are synchronously retracted and released by the drum 25, so as to drive the monitoring part 4 to rise and fall, thereby improving the monitoring depth of the monitoring part 4. Figure 8 When the driving steel cable 26 is pulled upward alone, the block 261 of the driving steel cable 26 will be pulled into the pull groove 242 of the immersed tube 241, thereby causing the immersed tube 241 to be offset and tilted. Since the driving steel cable 26 has a certain rigidity, it can keep the immersed tube 241 and the monitoring component 4 moving obliquely downward of the float 1, thereby changing the monitoring range of the monitoring component 4.

[0050] It is worth noting that, referring to Figure 3-4 As shown, the waterproof central control box 3 is provided with a drive motor 32 and two sets of electromagnetic telescopic components 33, wherein:

[0051] The drive motor 32 selectively drives the receiving ring 211 to perform 360° limited rotation or drives the reel 25 to retract or release the cable through the expansion and contraction switching of the electromagnetic expansion member 33;

[0052] When the electromagnetic telescopic member 33 is extended, the telescopic portion thereof locks the rotational freedom of the spool 25 .

[0053] Specifically, the shaft 22 is externally sleeved with a shaft disc 21 mounted via a bearing, the axis of the reel 25 passes through the eccentric portion of the shaft disc 21 and extends into the waterproof central control box 3, the axis end of the reel 25 is sleeved with a retracting gear 251, a lifting bracket 34 is installed between the telescopic portions of the two electromagnetic telescopic members 33, a locking ring 36 is installed below the end of the lifting bracket 34, a switching disk 31 is coaxially connected between the lifting bracket 34 and the locking ring 36 via a bearing, the locking ring 36 and the switching disk 31 move synchronously along the axis direction with the telescopic portion of the electromagnetic telescopic member 33, and the locking ring 36 is provided at the bottom of the lifting bracket 34. The inner wall of the ring 36 is provided with a locking groove 361 that meshes with the gear teeth on the surface of the retracting gear 251. This allows the locking groove 361 of the locking ring 36 to move upward from the bottom to the top and mesh with the retracting gear 251 when the electromagnetic telescopic member 33 drives the switching disk 31 and the locking ring 36 to move upward. Since the locking ring 36 itself cannot rotate, it can limit the retracting gear 251, thereby preventing the drum 25 from being pulled by the connecting cable 24 and the driving steel cable 26 due to the weight of the monitoring member 4 or the impact of water flow when the monitoring position of the monitoring member 4 is adjusted by the switching disk 31, thereby affecting the monitoring position coordinates.

[0054] And, in Figure 4 In the embodiment, the outer periphery of the switching disk 31 is evenly distributed with driving teeth and grooves 311, and the output shaft of the driving motor 32 is sleeved with a driving gear 321 that meshes with the driving teeth and grooves 311. The tooth length of the driving gear 321 is consistent with the movable length of the switching disk 31 as the electromagnetic telescopic part 33 is extended and contracted. This ensures that when the switching disk 31 is adjusted to lift and lower the switching storage ring 211 for 360° limited rotation or the reel 25 is driven to perform cable retraction and release, the driving gear 321 always remains in engagement with the driving teeth and grooves 311 of the switching disk 31, ensuring that the driving motor 32 can drive the switching disk 31 to rotate at any time, and can perform continuous operation when adjusting the monitoring direction and monitoring range, thereby improving the positioning accuracy of the monitoring component 4 during large-scale monitoring.

[0055] Furthermore, the steering gear 221 is sleeved on one end of the shaft rod 22 located at the top of the shaft disc 21, and the steering gear 221 and the retracting gear 251 are staggered up and down. An upper transmission tooth groove 313 is provided on the inner side of the upper end portion of the switching disc 31 for engaging with the steering gear 221, and a lower transmission tooth groove 312 is provided on the inner side of the lower end portion of the switching disc 31 for engaging with the retracting gear 251. Since the steering gear 221 and the retracting gear 251 are staggered, the driving tooth groove 311 of the switching disc 31 switches with the expansion and contraction of the electromagnetic telescopic member 33, and can engage with the steering gear 221 and the retracting gear 251 independently, thereby preventing the switching disc 31 from simultaneously driving the steering gear 221 and the retracting gear 251 to rotate, preventing the relative position of the monitoring member 4 and the float 1 from changing when adjusting the monitoring direction, or preventing the monitoring member 4 from changing the monitoring direction when adjusting the relative position with the float 1, thereby improving the monitoring coordinate accuracy.

[0056] The storage ring 211 is provided with two sets of interlocking frames 27 at the corresponding position of the support tube 23. The two interlocking frames 27 are connected by a separation plate 272. The connecting cable 24 and the driving steel cable 26 are distributed at the front and rear parts of the separation plate 272. The two interlocking frames 27 are located at the bottom of one side of the driving steel cable 26 and are also connected to an auxiliary roller 273 through a rotating shaft. When the connecting cable 24 and the driving steel cable 26 are released by the reel 25 through the two sets of interlocking frames 27, the auxiliary roller 273 will squeeze the block 261 on the outside of the driving steel cable 26 and merge it into the groove 242 on one side of the outer immersed tube 241 of the connecting cable 24. When the two are synchronously wound by the reel 25, they enter the storage box 2 When the cable 26 is pulled upward, the block 261 moves in the groove 242, so that the side of the submerged tube 241 outside the connecting cable 24 is pulled and tilted at a certain angle, thereby realizing the bending state of the connecting part (the linkage cable group connected to the monitoring part 4) with the joint cooperation of multiple groups of submerged tubes 241, and the monitoring part 4 can make a fan-shaped angle offset obliquely downward to the float 1, thereby improving the monitoring range.

[0057] exist Figure 6 and Figure 7In the embodiment, the two facing surfaces of the two interlocking frames 27 are provided with inclined grooves 271 corresponding to the driving steel cables 26. The two inclined grooves 271 are arranged to be tilted from top to bottom and back to back. Slide blocks 282 are slidably installed inside the two inclined grooves 271. A lifting block 283 is provided at one end of the slide block 282 close to the driving steel cables 26. A traction frame 28 is slidably provided inside the two interlocking frames 27. The traction frame 28 is connected to the top of the two slide blocks 282 through the traction frame 28, and a traction rope 281 passing through the shaft 22 is connected between the traction frame 28 and the lifting bracket 34, so that the driving steel cables 26 can be pulled upward by themselves, thereby driving multiple groups of immersed tubes 2 41 realizes the bending state of the connecting piece, and by pulling the traction rope 281 when the lifting bracket 34 rises, the traction bracket 28 at the other end thereof can drive the slider 282 to slide upward in the inclined groove 271 of the interlocking frame 27. Since the inclined groove 271 is inclined from top to bottom and back to back, when the slider 282 slides upward, the pulling block 283 at its end will move closer to the middle, thereby being able to lift the clamping block 261 and lift the traction drive cable 26. During the lifting process, the lifting bracket 34 is in an upward moving state, so the above-mentioned locking ring 36 will synchronously lock the retracting and releasing gear 251 of the reel 25, preventing the movement of the reel 25 from causing the connecting cable 24 to move along with the drive cable 26;

[0058] When it is necessary to retract the monitoring component 4 and lower the float 1 through the retraction box 2, the electromagnetic telescopic component 33 drives the lifting bracket 34 to move downward, so that the driving steel cable 26 is lowered and set parallel to the connecting cable 24, unlocking the reel 25, and allowing the switching disk 31 to engage with the retraction gear 251 through the lower transmission tooth groove 312. The driving motor 32 drives the switching disk 31 to rotate through the driving gear 321, and the switching disk 31 drives the reel 25 to rotate, reeling the connecting cable 24 and the driving steel cable 26. At this time, the monitoring component 4 can be retracted under the float 1 again.

[0059] A control device 35 is installed inside the waterproof central control box 3. The control device 35 includes a power supply and a PLC. The PLC is integrated with a communication component, which is usually one or more of GPRS / 4G, WIFI or Bluetooth. It is electrically connected to the drive motor 32 and the electromagnetic telescopic part 33 through a PLC model S4-400. Real-time control of the drive motor 32, the electromagnetic telescopic part 33 and the communication component is achieved through PLC programming, and positioning, control and data transmission of the monitoring depth, monitoring direction and monitoring range of the monitoring part 4 are completed, with a high degree of automation.

[0060] This solution designs an intelligent floating water quality monitor, which is controlled by a linkage cable group consisting of a parallel connecting cable 24 (with a submerged tube 241 structure) and a driving steel cable 26 (with a clamping block 261). The monitoring depth of the monitoring component 4 can be adjusted by synchronous retraction and extension, and the driving steel cable 26 can be pulled up separately to tilt the submerged tube 241 to form a monitoring offset angle, so that the monitoring component 4 can move in a circumferential fan-shaped range along the axis direction of the float 1, thereby improving the monitoring range.

[0061] The waterproof central control box 3 features a dual-mode switching mechanism driven by an electromagnetic telescopic element 33. A lifting bracket 34 controls the meshing of the switching plate 31 with the steering gear 221 and the retraction gear 251, respectively, enabling 360-degree adjustment of the monitoring position and independent control of cable retraction and extension. The interlocking frame 27 and the inclined slot 271, in conjunction with the traction rope 281, precisely control the displacement of the drive cable 26 via the lifting block 283 when the electromagnetic telescopic element 33 is activated. Simultaneously, the separation plate 272 and auxiliary roller 273 ensure orderly separation and engagement of the cables during retraction and extension. This eliminates the need for multiple motors to drive each, improving internal redundancy and reducing costs while also reducing overall weight.

[0062] Compared with traditional floating water quality monitors, this solution solves the problem that traditional fixed-depth monitoring modes cannot adapt to complex water environments. By linking the cable group and the immersed tube 241 structure, the combined adjustment of monitoring depth and horizontal displacement is achieved.

[0063] It improves the limitations of the traditional single control mode and realizes the decoupling control of monitoring azimuth and depth through the dual-mode switching mechanism driven by the electromagnetic telescopic part 33, greatly improving the positioning accuracy. At the same time, it integrates solar power supply and PLC intelligent control system, which significantly improves the reliability and automation level of outdoor long-term monitoring.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
