Description

A buoy deployment device for hydrological monitoring Technical Field

[0001] This invention relates to the field of buoy deployment device technology, and particularly to a buoy deployment device for hydrological monitoring. Background Technology

[0002] In hydrological monitoring, the precise deployment of buoys is crucial for ensuring the continuity and accuracy of monitoring data. Current buoy deployment relies on the hooks of traditional lifting and deployment devices, but this method has significant technical drawbacks. Existing hooks lack automatic alignment and hooking functions, requiring manual adjustment of the hook before deployment. This increases the difficulty of manual operation, reduces deployment efficiency, and necessitates personnel operating near the water's edge or from a boat, posing safety risks such as falling into the water. Furthermore, traditional hooks cannot automatically detach after deployment, requiring remote manual control or close-range assistance for separation. This not only prolongs the operation but also risks buoy displacement due to improper detachment, affecting the accuracy of hydrological data acquisition. These issues highlight the low efficiency and safety hazards associated with manual operation. Summary of the Invention

[0003] The main objective of this invention is to provide a buoy deployment device for hydrological monitoring, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A buoy deployment device for hydrological monitoring includes a mounting frame. A lifting and deployment device is fixedly mounted on the upper end of the mounting frame. A steel cable is installed on the lifting and deployment device. A positioning component is installed on one side of the steel cable. A deployment component is installed below the positioning component. The positioning component includes a fixed bent rod fixedly mounted on the telescopic rod of the lifting and deployment device. A circular tube is fixedly installed in the middle of the fixed bent rod. An upper limit ring is fixedly installed at the lower end of the circular tube. An outer sleeve is fixedly installed at the lower end of the upper limit ring. An inner sleeve is slidably installed on the inner side of the outer sleeve. The inner sleeve has a lower limit ring fixedly installed at its lower end. A spring is fixedly installed between the upper limit ring and the lower limit ring, near the outer sleeve and outside the inner sleeve. A fixing sleeve is fixedly installed at the lower end of the steel rope. A connector is fixedly installed at the lower end of the fixing sleeve. A sleeve block is fitted around the fixing sleeve and the connector. A guide shaft is fixedly installed on one side of the upper end of the sleeve block. Two sets of limiting plates are fixedly installed on the upper side of the guide shaft. A guide ring is fixedly installed at the lower end of the lower limit ring, corresponding to the position outside the fixing sleeve. A slot is opened on one side of the guide ring.

[0006] Preferably, the delivery assembly includes two sets of fixing plates fixedly disposed at the lower end of the sleeve block, a rotating shaft rotatably disposed between the two sets of fixing plates, a hook fixedly disposed at the lower end of the rotating shaft, a connecting rod fixedly disposed on one side of the rotating shaft, a counterweight fixedly disposed on the upper side of the connecting rod, two sets of rod sleeves fixedly disposed on the inner side of the sleeve block, toothed rods movably disposed on the inner side of each of the two sets of rod sleeves, ball sleeves fixedly disposed at the upper end of each of the two sets of toothed rods, ball bearings movably disposed on the inner side of each of the two sets of ball sleeves, gear rings fixedly disposed on the outer side of the rotating shaft near the two sets of toothed rods, and a limit bar fixedly disposed between the two sets of fixing plates near the other side.

[0007] Preferably, a conveying device is fixedly installed at one end of the mounting frame, and several sets of support rollers are rotatably arranged on the inner side of the conveying device near the conveyor belt. Several sets of placement rings are fixedly arranged on the outer side of the conveyor belt of the conveying device. An injection port is opened on the outer shell of the conveying device away from the mounting frame, and five sets of monitoring buoys are placed on the conveyor belt of the conveying device.

[0008] Preferably, the steel rope passes through the inner side of the round tube, outer tube, and inner tube and is connected to the fixed sleeve. The spring is in a compressed state. The fixed sleeve is fitted to the bottom of the lower limit ring. The sleeve head block is movably fitted on the outside of the fixed sleeve and the connector. The upper side of the sleeve head block is inclined and fits against the guide ring.

[0009] Preferably, the upper side of the guide shaft is arc-shaped near the two sets of limiting pieces, the guide shaft is engaged in the slot, the two sets of limiting pieces are respectively arranged inside and outside the guide ring, and the lower side of the guide ring is inclined.

[0010] Preferably, the two sets of hooks and toothed rods are located on both sides of the two sets of fixing plates, the connecting rod is inclined, and the weight of the counterweight is greater than the weight of the hooks and the two sets of toothed rods.

[0011] Preferably, the toothed rod passes through the upper ball bearing of the rod sleeve and rests on the lower end of the lower limiting ring. The toothed rod and the gear ring are meshed. The limiting rod limits the rotation angle of the hook along the rotating shaft.

[0012] Preferably, the conveying device provides a fixed conveying distance for the monitoring buoy each time, and several sets of support rollers and placement rings are arranged horizontally and evenly. The placement rings are adapted to the monitoring buoy, the release port meets the size of the monitoring buoy, and a lifting ring is fixedly provided on the upper side of the monitoring buoy.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Place the monitoring buoys to be deployed on the conveyor belt of the conveyor device, with the corresponding placement rings placed inside. At the same time, the lifting ring on the upper side of the monitoring buoy should face the hook side. During the subsequent deployment process, the conveyor device will transport each group of monitoring buoys a certain distance, so that the monitoring buoys are positioned at the deployment port and the lifting rings are positioned at the hook retraction position each time, so that each deployed monitoring buoy is automatically placed in a fixed position, which facilitates subsequent deployment work.

[0015] 2. The head block is pulled up by a steel cable, aligning the guide shaft with the guide ring. With the lower end of the guide ring tilted, the guide shaft rotates and slides along the guide ring, causing the lower deployment component and hook to rotate together until the guide shaft slides to the inside of the slot and engages. Simultaneously, the tilted surface of the head block contacts the guide ring, pushing the ball bearings and toothed rod downwards, driving the hook to rotate for easy deployment. The hook automatically aligns with the monitoring buoy's hook direction, and the lifting and deployment device moves back, causing the hook to move towards the monitoring buoy's lifting ring position. The hook is inserted into the ring, and the sliding mechanism between the outer and inner sleeves, combined with the elasticity of the spring, allows the head block to be pulled within a certain distance to adjust the height of the hook aligned with the lifting ring, and to move upwards to lift the monitoring buoy away from the conveyor belt of the conveyor device. Under the weight of the monitoring buoy, the counterweight block remains in the upper position when the steel cable is lowered. Thus, each time the monitoring buoy is deployed, the hook can automatically rotate to align with the lifting ring of the monitoring buoy and lift it to place it on the water surface, eliminating the tedious steps of manual adjustment and operation close to the edge of the boat.

[0016] 3. When the lifting and launching device drives the steel cable to lower the head block and launching component, the head block separates from the guide ring and the ball bearing separates from the lower limit ring. This continues until the monitoring buoy falls to the water surface and generates buoyancy. As the hook continues to descend, it disengages from the monitoring buoy's lifting ring and automatically rotates to release itself under the weight of the counterweight. No manual close-range assistance is required, and the hook release is completed quickly, saving the waiting and debugging time of traditional hook release. In addition, by pulling the hook upward with the steel cable, the lower limit ring pushes the toothed rod downward, driving the meshing gear ring and rotating shaft to rotate until it is restricted by the limit bar. Then, the rotating shaft drives the hook to the lower side to prepare for the next step of the work. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship as a relative relationship of orientation or position, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0028] Please refer to Figures 1-8. One embodiment of the present invention provides a buoy deployment device for hydrological monitoring, comprising a mounting frame 1. A lifting and deployment device 2 is fixedly mounted on the upper end of the mounting frame 1. A steel cable 3 is provided on the lifting and deployment device 2. A positioning component 4 is provided on one side of the steel cable 3. A deployment component 5 is provided below the positioning component 4. The positioning component 4 includes a fixed bent rod 41 fixedly mounted on the telescopic rod of the lifting and deployment device 2. A circular tube 42 is fixedly mounted in the middle of the fixed bent rod 41. An upper limit ring 43 is fixedly mounted at the lower end of the circular tube 42. An outer sleeve 44 is fixedly mounted at the lower end of the upper limit ring 43. An inner sleeve 45 is slidably mounted inside the outer sleeve 44. A lower limit ring 46 is fixedly installed at the lower end of the inner sleeve 45. A spring 47 is fixedly installed between the upper limit ring 43 and the lower limit ring 46 near the outer sleeve 44 and the outer side of the inner sleeve 45. A fixing sleeve 48 is fixedly installed at the lower end of the steel rope 3. A connector 49 is fixedly installed at the lower end of the fixing sleeve 48. A sleeve block 410 is fitted on the outer side of the fixing sleeve 48 and the connector 49. A guide shaft 411 is fixedly installed on one side of the upper end of the sleeve block 410. Two sets of limiting plates 412 are fixedly installed on the upper side of the guide shaft 411. A guide ring 413 is fixedly installed at the lower end of the lower limit ring 46 corresponding to the outer position of the fixing sleeve 48. A slot 414 is opened on one side of the guide ring 413.

[0029] The steel rope 3 passes through the inner side of the round tube 42, outer tube 44, and inner tube 45 and connects to the fixed sleeve 48. The spring 47 is in a compressed state. The fixed sleeve 48 is attached to the bottom of the lower limit ring 46. The sleeve block 410 is movably sleeved on the outside of the fixed sleeve 48 and the connector 49. The upper side of the sleeve block 410 is inclined and attached to the guide ring 413. The upper side of the guide shaft 411 is arc-shaped near the two sets of limit pieces 412. The guide shaft 411 is engaged in the slot 414. The two sets of limit pieces 412 are respectively set inside and outside the guide ring 413. The lower side of the guide ring 413 is inclined.

[0030] The head block 410 is pulled up by the steel cable 3, so that the guide shaft 411 is aligned with the guide ring 413. With the lower end of the guide ring 413 tilted, the guide shaft 411 rotates and slides along the guide ring 413, causing the lower delivery component 5 and the hook 53 to rotate together until the guide shaft 411 slides to the inside of the slot 414 and engages. At the same time, the inclined surface of the head block 410 is in contact with the guide ring 413 and pushes the ball bearing 59 and the toothed rod 57 to move downward, driving the hook 53 to rotate for easy delivery (as shown in Figure 6). The hook 53 automatically aligns with the hook direction of the monitoring buoy 10, and the lifting and delivery device 2 moves back to make the hook 53... The buoy 10 is moved to the ring position and inserted into the ring opening. The sliding setting of the outer sleeve 44 and the inner sleeve 45, combined with the elastic action of the spring 47, pulls the head block 410 to adjust the height of the hook 53 aligned with the ring within a certain distance, and moves upward to pull the buoy 10 away from the conveyor belt of the conveyor device 6. Under the weight of the buoy 10, the counterweight block 55 is always kept in the upper position when the steel rope 3 is lowered. Thus, each time the buoy 10 is deployed, the hook 53 can automatically rotate to align with the ring of the buoy 10 and lift it to place it on the water surface, eliminating the tedious steps of manual adjustment and operation close to the edge of the boat.

[0031] The delivery component 5 includes two sets of fixing plates 51 fixedly installed at the lower end of the sleeve block 410. A rotating shaft 52 is rotatably installed between the two sets of fixing plates 51. A hook 53 is fixedly installed at the lower end of the rotating shaft 52. A connecting rod 54 is fixedly installed on one side of the rotating shaft 52. A counterweight block 55 is fixedly installed on the upper side of the connecting rod 54. Two sets of rod sleeves 56 are fixedly installed inside the sleeve block 410. A toothed rod 57 is movably installed inside the two sets of rod sleeves 56. A ball sleeve 58 is fixedly installed at the upper end of the two sets of toothed rods 57. A ball bearing 59 is movably installed inside the two sets of ball sleeves 58. A gear ring 510 is fixedly installed on the outer side of the rotating shaft 52 near the two sets of toothed rods 57. A limit bar 511 is fixedly installed between the two sets of fixing plates 51 near the other side.

[0032] Two sets of hooks 53 and toothed rods 57 are located on both sides of two sets of fixed plates 51. The connecting rod 54 is inclined. The weight of the counterweight 55 is greater than the weight of the hooks 53 and the two sets of toothed rods 57. The toothed rod 57 passes through the upper ball bearing 59 of the sleeve 56 and rests on the lower end of the lower limit ring 46. The toothed rod 57 and the gear ring 510 are meshed. The limit bar 511 limits the rotation angle of the hooks 53 along the rotating shaft 52.

[0033] When the lifting and launching device 2 drives the steel rope 3 to lower the head block 410 and the launching component 5, the head block 410 separates from the guide ring 413 and the ball bearing 59 separates from the lower limit ring 46. Until the monitoring buoy 10 falls to the water surface and generates buoyancy, when the hook 53 continues to descend, the hook 53 disengages from the monitoring buoy 10's lifting ring and, under the weight of the counterweight 55, the hook 53 automatically rotates and disengages. No manual close-range assistance is required, and the disengagement is completed quickly, saving the waiting and debugging time of traditional disengagement (as shown in Figure 7). In addition, by pulling the hook 53 upward with the steel rope 3, after the positioning component 4 rotates, the lower limit ring 46 pushes the toothed rod 57 to move downward, driving the meshing gear ring 510 and the rotating shaft 52 to rotate until it is restricted by the limit bar 511. Then, the rotating shaft 52 drives the hook 53 to the lower side to prepare for the next step of work.

[0034] A conveying device 6 is fixedly installed at one end of the mounting frame 1. Several sets of support rollers 7 are rotatably arranged on the inner side of the conveying device 6 near the conveyor belt. Several sets of placement rings 8 are fixedly arranged on the outer side of the conveyor belt of the conveying device 6. An injection port 9 is opened on the outer side of the outer shell of the conveying device 6 away from the mounting frame 1. Five sets of monitoring buoys 10 are placed on the conveyor belt of the conveying device 6.

[0035] The conveying device 6 conveys the monitoring buoy 10 at a fixed distance each time. Several sets of support rollers 7 and placement rings 8 are arranged horizontally and evenly. The placement rings 8 are adapted to the monitoring buoy 10. The release port 9 meets the size of the monitoring buoy 10. A hanging ring is fixedly installed on the upper side of the monitoring buoy 10.

[0036] The monitoring buoys 10 to be deployed are placed on the conveyor belt of the conveyor device 6, and the corresponding placement rings 8 are placed in them. At the same time, the hanging ring on the upper side of the monitoring buoy 10 faces the hook 53. During the subsequent deployment process, the conveyor device 6 transports each group of monitoring buoys 10 a certain distance, so that the monitoring buoys 10 correspond to the deployment port 9 and the hanging ring corresponds to the position when the hook 53 is extended each time. This allows the monitoring buoys 10 deployed each time to be automatically placed in a fixed position, which is convenient for subsequent deployment work.

[0037] Working principle: In use, the monitoring buoy 10 to be deployed is first placed on the conveyor belt of the conveyor device 6, with the corresponding placement ring 8 placed inside. Simultaneously, the lifting ring on the upper side of the monitoring buoy 10 faces the hook 53. During deployment, the conveyor device 6 transports each group of monitoring buoys 10 a certain distance, ensuring that the monitoring buoy 10 corresponds to the deployment port 9 and the lifting ring corresponds to the position when the hook 53 retracts each time. This automatically places each deployed monitoring buoy 10 into a fixed position, facilitating subsequent deployments. During deployment, the steel cable 3 pulls up the head block 410, aligning the guide shaft 411 with the guide ring 413, cooperating with the guide ring 413. The lower end of the 13 is inclined, and the guide shaft 411 rotates and slides along the guide ring 413, causing the lower delivery component 5 and the hook 53 to rotate together until the guide shaft 411 slides to the inside of the slot 414 and engages. At the same time, the inclined surface of the sleeve block 410 is in contact with the guide ring 413 and cooperates to push the ball 59 and the toothed rod 57 to move downward, driving the hook 53 to rotate for easy delivery (as shown in Figure 6). The hook 53 automatically aligns with the hook direction of the monitoring buoy 10. With the lifting and delivery device 2 moving back, the hook 53 moves towards the position of the monitoring buoy 10 and inserts into the ring. The sliding arrangement of the outer sleeve 44 and the inner sleeve 45, combined with the elasticity of the spring 47, Under the action of the lifting device 6, the height of the hook 53 aligned with the lifting ring can be adjusted within a certain distance by pulling the head block 410, and the upward movement can lift the monitoring buoy 10 away from the conveyor belt of the conveying device 6. Under the weight of the monitoring buoy 10, the counterweight 55 of the hook 53 remains in the upper position when the steel cable 3 is lowered. Thus, each time the monitoring buoy 10 is deployed, the hook 53 can automatically rotate to align with the lifting ring of the monitoring buoy 10 and lift it to place it on the water surface, eliminating the tedious steps of manual adjustment and operation close to the edge of the boat. When the lifting and deployment device 2 drives the steel cable 3 to lower the head block 410 and the deployment component 5, the head block 410 separates from the guide ring 413 and the ball bearing 59 and the guide ring 413 separate. The lower limit ring 46 separates until the monitoring buoy 10 falls to the water surface and generates buoyancy. Therefore, when the hook 53 continues to move downward, the hook 53 disengages from the monitoring buoy 10 and is automatically rotated and disengaged under the weight of the counterweight 55. No manual close-range assistance is required to quickly complete the disengagement, saving the waiting and debugging time of traditional disengagement (as shown in Figure 7). In addition, the hook 53 is pulled upward by the steel cable 3. After the positioning component 4 rotates, the lower limit ring 46 pushes the toothed rod 57 to move downward, driving the meshing gear ring 510 and the rotating shaft 52 to rotate until it is restricted by the limit bar 511. Then, the rotating shaft 52 drives the hook 53 to the lower side to prepare for the next step of the work.
