Description

Technical Field

[0001] This utility model relates to the field of buoyancy device technology, and in particular to a buoyancy device for a float. Background Technology

[0002] The float needs to be submerged and resurfaced according to requirements. Once submerged, an airtightness test can be performed to ensure that internal components are not damaged by water ingress. The float can be used as an underwater diving device, allowing it to move underwater to explore the seabed. After being retrieved from the sea, the device is immersed in a pool to remove water-soluble impurities such as salt from its surface. In existing technology, counterweights are placed on the float. Due to the float's high buoyancy and long dimensions, a large counterweight is required to sink it. Adding and removing the counterweight is difficult, making it hard to control the float's balance, determine its sinking depth, and risk deformation or even damage.

[0003] Therefore, there is an urgent need for a floating device to solve the above-mentioned technical problems. Utility Model Content

One end of the steel cable is fixed to the support frame located at the bottom of the pool, and the other end passes around the movable pulley and the fixed pulley in sequence and is connected to the motor. The motor is capable of winding or unwinding the steel cable.

[0009] The motor unwinds or rewinds the steel cable to raise or lower the locking ring, causing the float to float and sink in the water of the pool.

[0010] Furthermore, the lifting assembly also includes a winding reel, which is rotatably mounted on the support frame, and the output end of the motor is connected to the winding reel.

[0013] Furthermore, the locking assembly also includes a hinge shaft, through which the first end of the first half-ring and the first end of the second half-ring are hinged.

[0014] Furthermore, the lifting assembly also includes a tensioner for tensioning the steel cable.

[0015] Furthermore, the buoyancy device of the float also includes a mounting frame, which is fixedly mounted on the locking ring, and the movable pulley is rotatably mounted on the mounting frame.

[0016] Furthermore, the mounting bracket includes a connecting part and a mounting part connected together, the connecting part being welded to the locking ring, and the movable pulley being rotatably disposed on the mounting part.

[0019] Furthermore, the floating and sinking device of the float also includes a controller, and the limiting component also includes a limit switch. The limit switch is disposed on the limiting seat and can limit the float. The limit switch and the motor are both connected to the controller.

[0020] The beneficial effects of this utility model are as follows:

[0021] The floating and sinking device provided by this utility model includes a support frame, a locking assembly, and a lifting assembly. The support frame is installed in a water tank and is at least partially submerged in the water. The locking assembly includes a locking ring that can lock the float.

[0036] like Figures 1-3As shown, this embodiment provides a floating device for a float 3 in a pool. The device includes a support frame 1, a locking assembly 2, and a lifting assembly 4. The support frame 1 is installed in the pool and at least partially submerged. The locking assembly 2 includes a locking ring 21 that locks the float 3. The lifting assembly 4 includes a steel cable 41, a movable pulley 42, a fixed pulley 43, and a motor. The movable pulley 42 is rotatably mounted on the locking ring 21. The fixed pulley 43 is mounted on the support frame 1 located at the bottom of the pool. The motor is mounted on the support frame 1. One end of the steel cable 41 is fixed to the support frame 1 at the bottom of the pool, and the other end passes sequentially around the movable pulley 42 and the fixed pulley 43 and is connected to the motor. By unwinding or rewinding the steel cable 41 by the motor, the locking ring 21 is raised or lowered, causing the float 3 to float or sink in the pool water. The unwinding or rewinding of the steel cable 41 by the motor makes the float 3 float and sink conveniently and provides precise lifting and lowering displacement. When the motor winds up the steel cable 41, pulling it down until the tension in the cable exceeds the buoyancy of the float 3, the cable 41 causes the locking ring 21 to move downwards, causing the float 3 to sink to the bottom of the pool. When the motor unwinds the cable 41, removing the force on it, the float 3 can float again due to the buoyancy of the water in the pool. Compared to placing a counterweight on the float 3, this method solves problems such as the counterweight easily slipping into the water, difficulty in placing it on the float 3, difficulty in controlling the float 3's attitude, and difficulty in accurately controlling the float 3's depth in the water. Furthermore, the float 3 is less prone to deformation under pressure, reducing the chance of damage. Motor-controlled buoyancy allows for precise control of the float 3's depth in the water, improving work efficiency.

[0037] Specifically, the motor is mounted on a support frame 1 located on the edge of the pool.

[0038] Furthermore, the lifting assembly 4 also includes a winding reel 44, which is rotatably mounted on the support frame 1, and the output end of the motor is connected to the winding reel 44. When the motor rotates forward, it drives the winding reel 44 to rotate forward, thereby winding the steel cable 41 around and onto the shaft of the winding reel 44, causing the steel cable 41 to generate a pulling force that pulls the locking ring 21, thereby pulling down the float 3 and causing the float 3 to sink to the bottom of the pool. When the motor rotates in reverse, it drives the winding reel 44 to rotate in reverse, thereby unwinding the steel cable 41 from the shaft of the winding reel 44, so that the steel cable 41 no longer generates a force, and the float 3 automatically floats to the surface under the action of buoyancy, thereby achieving the floating of the float 3. The locking ring 21 can be opened to lift the float 3 away.

[0039] In this embodiment, the main weight of the support frame 1 is in the water, ensuring that the support frame 1 will not float in the water and ensuring the stability of the support frame 1 in the pool.

[0040] like Figure 1As shown, the support frame 1 is an integrated design in the shape of an L, including an integrally formed base frame 11 and a vertical frame 12. The base frame 11 is placed on the bottom of the pool, and the vertical frame 12 is vertically mounted on the base frame 11 and located on the edge of the pool. Most of the vertical frame 12 is immersed in the water. This embodiment does not limit this.

[0041] Specifically, the support frame 1 can be hoisted into or removed from the water tank for maintenance.

[0042] Specifically, the fixed pulley 43 is mounted on the base frame 11, and the motor is mounted on the upright frame 12.

[0043] In this embodiment, there are at least two fixed pulleys 43, which are spaced apart on the base frame 11, and the rope is wound around the two fixed pulleys 43.

[0044] Furthermore, the support frame 1 also includes a reinforcing rod 13, which is disposed between the upright frame 12 and the base frame 11. Specifically, the reinforcing rod 13 is inclinedly disposed between the upright frame 12 and the base frame 11, thereby increasing the strength of the support frame 1.

[0045] Furthermore, the lifting assembly 4 also includes a tensioner 45, which is used to tension the steel cable 41. When there is no float 3 on the locking ring 21, the steel cable 41 is in a slack state, and the locking ring 21 is resting on the edge of the pool. The tensioner 45 can then... Figure 1 The steel cable 41 between the rightmost fixed pulley 43 and the winding reel 44 is always taut to ensure that the steel cable 41 can be smoothly wound when the winding reel 44 is winding.

[0046] Specifically, the tensioner 45 includes a tension pulley 451, a drum 452, a tension rope 453, and an anti-rotation component. The tension pulley 451 is fixed to the base frame 11 of the support frame 1. One end of the tension rope 451 is connected to the steel cable 41, and the other end passes around the tension pulley 451 and is wound around the spool of the drum 452. The spool of the drum 452 is rotatably mounted on the upright frame 12 of the support frame 1. An anti-rotation component is connected to the spool of the drum 452, which prevents the spool of the drum 452 from rotating. As the float 3 sinks, the anti-rotation device is not engaged, the tension rope 453 is long enough, and the shaft of the drum 452 can rotate freely to provide a suitable length of tension rope 453 to follow the movement of the steel cable 41. When the float 3 sinks to a suitable position, the length of the tension rope 453 can be finely adjusted by rotating the shaft of the drum 452 to keep the steel cable 41 taut. Then, the anti-rotation device fixes the shaft of the drum 452, preventing it from rotating and thus ensuring... The steel cable 41 is taut. When the float 3 rises, the anti-rotation device stops working, and the motor reverses, which may cause the steel cable 41 to loosen momentarily. At this time, the tension rope 453 can be lengthened or shortened by rotating the reel of the drum 452 to tighten the steel cable 41. During the rising of the float 3, the length of the tension rope 453 can be adjusted at any time according to the state of the steel cable 41 by rotating the reel of the drum 452. In other words, during the tensioning of the steel cable 41, the tension rope 453 may lengthen or shorten.

[0047] In this embodiment, the power source for rotating the roller 452 is not limited. It can be operated manually or a common power source such as a motor can be used, as long as the rotation of the roller 452 can be flexibly controlled.

[0048] Furthermore, an outer shell is provided on the drum 452, and the outer shell is fixed on the upright frame 12. An anti-rotation member is connected to the shaft of the drum 452, and an anti-rotation groove is opened on the outer shell. When the anti-rotation member is inserted into the anti-rotation groove, the shaft of the drum 452 is stopped from rotating; when the anti-rotation member is removed from the anti-rotation groove, the shaft of the drum 452 can rotate freely.

[0049] like Figure 2 As shown, the locking assembly 2 also includes a first latch 23 and a second latch 24. The float 3 is fitted inside the locking ring 21, which has an opening 22. The first latch 23 and the second latch 24 are respectively located on both sides of the opening 22. The first latch 23 can be locked onto the second latch 24. The arrangement of the first latch 23 and the second latch 24 allows the opening 22 of the locking ring 21 to be opened or closed, so that the float 3 can be engaged and locked inside the locking ring 21.

[0050] Furthermore, the locking ring 21 includes a first half-ring 211 and a second half-ring 212. The first end of the first half-ring 211 is hinged to the first end of the second half-ring 212. A first latch 23 is provided on the second end of the first half-ring 211, and a second latch 24 is provided on the second end of the second half-ring 212. The hinge of the first half-ring 211 and the second half-ring 212 allows rotation between the first half-ring 211 and the second half-ring 212 when the first latch 23 and the second latch 24 are open. This facilitates the insertion of the float 3 into the locking ring 21 and prevents damage to the float 3, thus providing a certain degree of protection for the float 3.

[0051] Furthermore, the locking assembly 2 also includes a hinge shaft 25, through which the first end of the first half-ring 211 and the first end of the second half-ring 212 are hinged.

[0052] In this embodiment, the locking ring 21 is made of high-speed steel, which has good corrosion resistance, a certain degree of rust prevention, and a long service life.

[0053] like Figure 1 and Figure 2 As shown, the buoyancy device of the float also includes a mounting frame 5, which is fixedly mounted on the locking ring 21, and the movable pulley 42 is rotatably mounted on the mounting frame 5.

[0054] Furthermore, the mounting frame 5 includes a connecting part 51 and a mounting part 52 connected together. The connecting part 51 is welded to the locking ring 21, and the movable pulley 42 is rotatably mounted on the mounting part 52. This arrangement allows the movable pulley 42 to maintain rotation while also being connected to the locking ring 21. The movable pulley 42 can change the direction of the steel cable 41, making it easier for the motor to pull the float 3.

[0055] like Figure 3 As shown, the buoyancy device also includes a limiting component 6, which is used to limit and stabilize the buoy 3 submerged in the water. The limiting component 6 includes a limiting seat 61, which is mounted on a support frame 1 located at the bottom of the pool. The buoy 3 can be limited to the limiting seat 61. The limiting seat 61 keeps the buoy 3 in a relatively central position in the pool, preventing the buoy 3 from swaying after submerging in the water, and thus preventing the buoy 3 from hitting the pool wall and being damaged.

[0056] Specifically, the limiting seat 61 is mounted on the base frame 11 and is located on both sides of the movable pulley 42, separate from the fixed pulley 43, to prevent the limiting seat 61 from interfering with the lifting assembly 4.

[0057] Furthermore, the limiting seat 61 has a limiting surface 611, the contour of which is adapted to the contour of the float 3.

[0058] In this embodiment, the limiting surface 611 is an arc surface, the float 3 is a float, and the arc surface is adapted to the surface of the float that contacts the arc surface.

[0059] When the buoyancy device provided in this embodiment pulls the float 3 into the water for immersion to remove impurities from the surface of the float 3, the size of the support base 61 can be set to be smaller. Under the premise of ensuring the limiting effect of the support base 61 on the float 3, the contact area between the support base 61 and the float 3 is reduced, thereby making the effect of removing impurities from the surface of the float 3 better.

[0060] Furthermore, the buoyancy device also includes a controller, and the limiting component 6 includes a limit switch 62. The limit switch 62 is mounted on the limiting seat 61 and can limit the buoy 3. Both the limit switch 62 and the motor are connected to the controller. Specifically, the limit switch 62 is located at a preset position on the limiting surface 611. When the buoy 3 sinks to the preset position on the limiting surface 611, the limit switch 62 is triggered and sends a signal. The controller sends a command to the motor according to the signal sent by the limit switch 62, and the controller controls the motor to stop running to prevent the buoy 3 from overtraveling when sinking and to avoid the motor continuing to pull the buoy 3 after it sinks to contact the limiting seat 61, which would cause damage to the buoy 3.

[0061] In this embodiment, the limit switch 62 can be a Xunhe SD8112.

[0062] In other alternative embodiments, instead of a controller and limit switch 62, the motor has a manual switch to control the start and stop of the motor, thereby controlling the operation and stop of the reel 44. The manual switch allows for slow adjustment of the float 3's position in the pool, preventing the float 3 from sinking to contact the limit seat 61 and causing damage by the steel cable 41 continuing to pull on it.

[0063] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
