Description

Technical Field

[0001] This utility model relates to the field of marine water quality testing technology, and in particular to an underwater suspension mechanism for maintaining the stable attitude of a sensor. Background Technology

[0002] Marine 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 status. Water quality sensors are commonly used equipment for water quality detection. They can sense the information being measured and transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording, and control.

[0003] When using existing water quality testing equipment, the main body of the equipment is first floated on the water surface by buoyancy. Then, the testing unit is lowered into the water area by a wire or guide rod for testing. However, when the water flow is fast, it will generate an uneven force on the equipment, which will cause the equipment to tilt or rotate. At the same time, when the lowered wire is retrieved, it will become tangled and knotted, resulting in severe wear of the wire and affecting its service life. Utility Model Content

[0029] The technical solution provided by this utility model will be further illustrated below with reference to the embodiments.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-3 The underwater suspension mechanism for maintaining sensor posture stability provided in this embodiment includes a housing 1, and each side of the housing 1 is equipped with a buoyancy box 3 via at least one telescopic mechanism 2. Figure 1 The diagram shows that each side of the shell 1 is equipped with a buoyancy box 3 via two telescopic mechanisms 2. Figure 2 As shown, each telescopic mechanism 2 includes a telescopic seat 10, a connecting rod 9, and a pin 12; one end of the connecting rod 9 is fixedly connected to the side of the buoyancy box 3, and the other end is slidably connected to the telescopic seat 10; the supporting area of ​​the underwater hoisting mechanism is adjusted by the sliding distance of the connecting rod 9; both the telescopic seat 10 and the connecting rod 9 are provided with multiple through holes 11, and the pin 12 passes through the through holes 11 through the telescopic seat 10 and the connecting rod 9, thereby stably fixing the connecting rod 9. Specifically, the telescopic seats 10 of the multiple telescopic mechanisms 2 are symmetrically installed on the outside of the housing 1, as shown in the figure. Figure 2 As shown, the telescopic seat 10 is provided with a sliding groove, and a connecting rod 9 is slidably connected in the sliding groove. The other end of each connecting rod 9 is fixedly connected to the side of the buoyancy box 3 corresponding to the position. Each telescopic seat 10 is equipped with multiple pins 12, and the multiple pins 12 pass through the connecting rod 9 and extend outward. Each telescopic seat 10 and the connecting rod 9 are provided with multiple through holes 11, and each pin 12 passes through the corresponding through hole 11. It should be noted that the number of pins 12 on each telescopic seat 10 is at least two, so as to stabilize and fix the connecting rod 9. By adjusting the sliding distance of the connecting rod 9, the support area of ​​the device can be adjusted, so as to maintain stability in waters with high flow rates and avoid overturning.

[0032] like Figure 2As shown, each buoyancy tank 3 is equipped with an airbag 8. By adjusting the water volume inside the airbag 8, the buoyancy of the airbag 8 is adjusted, thereby adjusting the center of gravity and attitude of the device in the water to maintain stability. Specifically, a first water pump 4 and a second water pump 6 are respectively installed on the top surface of each buoyancy tank 3, and each first water pump 4 and second water pump 6 is connected to the corresponding airbag 8. Specifically, each first water pump 4 and second water pump 6 is connected to the corresponding airbag 8 through a corrugated pipe. Each first water pump 4 is connected to a water inlet pipe 5, and the horizontal plane of one end of each water inlet pipe 5 is higher than the horizontal plane of the bottom surface of the airbag 8. Each second water pump 6 is connected to a drain pipe 7. It should be noted that water can be drawn from below the device through the water inlet pipe 5 and enter the airbag 8, and water can be discharged from the airbag 8 through the drain pipe 7, thereby adjusting the buoyancy of the airbag 8.

[0033] like Figure 3 As shown, the housing 1 contains a winding post 17, a drive mechanism, a pulley 16, a wire 18, and a detection unit 19. The winding post 17 is rotatably connected to the housing 1 and is driven to rotate by an external drive source. The drive mechanism drives the pulley 16 to perform linear reciprocating motion along a first parallel line, which is parallel to the axis of the winding post 17. The detection unit 19 is mounted on the bottom surface inside the housing 1 and is located between the first parallel line and the winding post 17. One end of the wire 18 is wound around the winding post 17, and the other end passes through the pulley 16 and connects to the detection unit 19. The pulley 16 guides the wire 18, so that the wire 18 is evenly wound around the winding post 17 along the axial direction of the winding post 17.

[0034] Specifically, the driving mechanism includes a reciprocating screw 13 and a screw sleeve 15. A winding post 17 and the reciprocating screw 13 are rotatably connected inside the housing 1, and are connected via a synchronous transmission assembly. The winding post 17 is driven to rotate by an external drive source, thereby driving the reciprocating screw 13 to rotate synchronously via the synchronous transmission assembly. A screw sleeve 15 is fitted onto the reciprocating screw 13, and a pulley 16 is provided on the side of the screw sleeve 15 near the winding post 17. A detection unit 19 is mounted on the inner bottom surface of the housing 1, and the mounting position of the detection unit 19 is located between the winding post 17 and the reciprocating screw 13. One end of a wire 18 is wound around the winding post 17, and the other end passes through the pulley 16 and connects to the detection unit 19. The lead screw sleeve 15 reciprocates linearly along the axis of the reciprocating lead screw 13 as the lead screw 13 rotates, thereby driving the pulley 16 to reciprocate linearly in sync. The pulley 16 guides the wire 18, so that the wire 18 is evenly wound around the outside of the winding post 17, thereby reducing the mutual tangling and knotting of the wire 18 and extending the service life of the wire 18.

[0035] Specifically, the reciprocating lead screw 13 has threads on its outer wall, and the lead screw sleeve 15 is threadedly connected to the reciprocating lead screw 13.

[0036] Specifically, the synchronous transmission assembly includes a synchronous pulley 20 and a synchronous belt 21. A synchronous pulley 20 is respectively installed at one end of the reciprocating screw 13 and the winding post 17, and the synchronous belt 21 is fitted onto the two synchronous pulleys 20. The winding post 17 is driven to rotate by an external drive source, and the synchronous belt 21 drives the reciprocating screw 13 to rotate synchronously.

[0037] A limiting rod 14 is also fixedly installed inside the housing 1. The limiting rod 14 is parallel to the reciprocating screw 13 and is located on the side of the reciprocating screw 13 away from the winding post 17. The screw sleeve 15 is provided with a guide hole. The limiting rod 14 passes through the guide hole and is slidably connected to the limiting rod 14. The limiting rod 14 limits the screw sleeve 15 so that it can only perform linear reciprocating sliding.

[0038] When using this invention, the device is first placed in water. The air bladders 8 inside the multiple buoyancy tanks 3 allow the device to float on the horizontal surface. Then, when the water flow velocity increases, the sliding distance of the multiple connecting rods 9 can be extended to increase the support area of ​​the device, thereby stabilizing the device. The amount of water in the corresponding air bladders 8 can be adjusted according to the direction of the water flow. The water in the air bladders 8 can be discharged through the second water pump 6 and the drain pipe 7 to increase buoyancy. Water can be drawn into the air bladders 8 through the first water pump 4 and the inlet pipe 5 to reduce buoyancy. By adjusting the buoyancy of the multiple air bladders 8, the center of gravity of the device can be changed, thereby keeping it stable in the water.

[0039] When the wire 18 is being retracted, the winding post 17 is driven to rotate by an external drive source, which in turn drives the reciprocating screw 13 to rotate through the synchronous pulley 20 and the synchronous belt 21. The limit rod 14 and the screw sleeve 15 drive the pulley 16 to slide back and forth along the axis of the reciprocating screw 13, thereby guiding the wire 18 so that it is evenly wound around the outside of the winding post 17, thereby reducing the mutual tangling and knotting of the wire 18 and extending the service life of the wire 18.

[0040] As can be seen from the above technical solutions, this utility model is simple to operate, can increase the support area of ​​the device, and can change the center of gravity of the device to counteract the uneven impact of the water flow, so that it can maintain the stability of its posture in the water. At the same time, when the wire is retrieved, the pulley slides back and forth to guide the wire, so that it is evenly wound on the winding post, avoiding tangling and knotting, which would affect its service life.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
