Description

Technical Field

[0001] This utility model relates to the field of water safety house technology, and in particular to a self-adjusting buffer mechanism for water safety houses to resist wind and waves. Background Technology

[0002] With the rapid development of the aquaculture industry, net enclosure aquaculture is now widely used in lakes and oceans. To facilitate effective monitoring of net enclosure aquaculture areas, cameras, various sensors, and other electronic control components are typically installed within the enclosure area for intelligent monitoring. Data transmission from these components requires corresponding equipment, which is then installed and stored in safe houses. Safe houses are also needed for temporary storage and rest during aquaculture operations such as feeding within the enclosure area. However, existing safe houses are usually only secured by anchor cables. When there are large waves, the tension of the anchor cables provides only cushioning, resulting in insufficient wave resistance and reduced overall safety. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a self-adjusting buffer mechanism for water safety houses that is resistant to wind and waves, which has the advantages of effectively buffering wind and waves and improving wind and wave resistance.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] According to an embodiment of this disclosure, a self-adjusting buffer mechanism for a floating safety house against wind and waves is provided, comprising:

[0006] Support frames are installed near the four corners of the safe house;

[0007] Rotary connection to the winding spindle of the support frame;

[0008] A take-up roller fixed to the take-up spindle;

[0009] A transmission gear fixed to the winding spindle;

[0010] A pressure relief pump that meshes with the transmission gear;

[0011] An anchor rope connected to the take-up roller, with one end of the anchor rope partially wound up to the take-up roller and the other end connected to a heavy anchor;

[0012] When the safe house is raised by wind and waves, the anchor rope pulls the winding spindle to rotate. The pressure relief pump is connected to a hydraulic buffer system to convert the power transmitted by the transmission gear into hydraulic power.

[0013] To achieve the above technical solution, when the waves are large, the water surface will rise due to the force of the waves, while the heavy anchor is anchored to the bottom. At this time, the anchor rope will be unwound from the winding roller and pull the winding main shaft to rotate. During the rotation of the winding main shaft, the transmission gear will rotate synchronously, thereby engaging the pressure relief pump to operate. The pressure relief pump is connected to the hydraulic buffer system to facilitate the flow of fluid, thereby converting the power transmitted by the transmission gear into hydraulic power, releasing the energy generated by the waves, achieving a buffering effect, which helps to further improve the wind and wave resistance of the safe house, and thus improves the safety of the safe house.

[0014] In some exemplary embodiments, the hydraulic cushioning system includes:

[0015] The oil tank is used to store and supply hydraulic oil, and the pressure relief pump is connected to the oil tank and pumps hydraulic oil from the oil tank to form hydraulic power;

[0016] A plurality of interconnected elastic dampers are provided, wherein the elastic dampers are connected to the pressure relief pump and are used to receive the hydraulic power to generate elastic buffer deformation, and the elastic dampers are also connected to the oil tank by a pressure relief oil circuit, wherein a pressure relief valve is provided on the pressure relief oil circuit for opening and releasing pressure after the elastic dampers reach the elastic deformation limit.

[0017] To achieve the above technical solution, when the pressure relief pump is driven by the meshing of the transmission gear, it pumps hydraulic oil from the oil tank and delivers it to the elastic damper to form hydraulic power. When the elastic damper receives this hydraulic power, it undergoes elastic deformation, thereby releasing the energy generated by the wind and waves and playing a buffering role. When the wind and waves are too high, causing the elastic damper to reach its elastic deformation limit, in order to avoid overloading the hydraulic buffer system, the pressure relief valve opens when it reaches the opening pressure, and the hydraulic pressure is discharged back into the oil tank.

[0018] In some exemplary embodiments, the elastic damper includes:

[0019] A damping box, wherein a sealed movable space is formed inside the damping box;

[0020] A piston that is slidably assembled inside the damping box and sealed to the damping box is used to receive hydraulic power;

[0021] An elastic reset member with one end connected to the damping box and the second end connected to the piston is used to generate elastic buffer deformation.

[0022] To achieve the above technical solution, under normal conditions, the piston is located at the inlet of the damping box under the action of the elastic reset component. When the pressure relief pump pumps hydraulic water in, it acts on the piston, driving the piston to move and compress the elastic reset component to form elastic deformation, thus achieving a buffering effect. When the water level drops or returns to normal, the pressure relief pump stops pumping hydraulic water into the elastic damper. At this time, the piston stops being subjected to force and can be reset under the action of the elastic force of the elastic reset component.

[0023] In some exemplary embodiments, the transmission gear also meshes with a bidirectional hydraulic motor, which is connected to the oil tank and the damping box, for synchronously depressurizing with the pressure relief pump or for driving the winding spindle to rotate in the opposite direction to wind up the anchor rope.

[0024] To achieve the above technical solution, a bidirectional hydraulic motor assists in pumping oil while the pressure relief pump is operating, dispersing a portion of the oil pressure and transmitting it to the elastic damper to improve the pressure relief and buffering effect. When the water level drops or returns to normal, the elastic damper resets, which drives the bidirectional hydraulic motor to drive the transmission gear to rotate in the opposite direction, thereby driving the winding spindle to rotate in the opposite direction and rewind the anchor rope onto the winding roller for the next buffering action.

[0025] In some exemplary embodiments, the transmission gear also meshes with a starter-generator integrated machine, which is connected to an energy storage device. The transmission gear can mesh with and drive the starter-generator integrated machine to rotate to generate electrical energy and store it in the energy storage device. Alternatively, the starter-generator integrated machine can act as a power source to drive the transmission gear to rotate in the opposite direction to wind up the anchor rope.

[0026] To achieve the above technical solution, when the transmission gear rotates, it can drive the generator to rotate and generate electrical energy to be stored in the energy storage device, thereby effectively utilizing the energy generated by wind and waves, and also assisting in buffering and depressurization; when the bidirectional hydraulic motor has insufficient driving force or malfunctions, it can actively control the generator to drive the transmission gear to rotate in the opposite direction to wind up the anchor rope, ensuring that there is a sufficient length of anchor rope for buffering when the next wind and wave arrives.

[0027] In some exemplary embodiments, a first check valve is also connected between the pressure relief pump and the elastic damper, the first check valve restricting the fluid flow to flow only from the pressure relief pump to the elastic damper.

[0028] In some exemplary embodiments, a second check valve is also connected between the inlet end of the first check valve and the pressure relief pump.

[0029] In some exemplary embodiments, the support frame includes: flanges located on both sides, and a plurality of support rods disposed between the two flanges, with the anchor rope passing through the gap between the two support rods located below.

[0030] The above technical solution is achieved by using a support rod to guide and block the anchor rope, making the winding and unwinding of the anchor rope smoother.

[0031] In some exemplary embodiments, the energy storage device is connected to an energy storage inverter, which is used to connect to electrical control equipment to provide electrical energy.

[0032] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0033] This utility model embodiment provides a self-adjusting buffer mechanism for a floating safety house to resist wind and waves. It is characterized by comprising: a support frame located near the four corners of the safety house; a winding main shaft rotatably connected to the support frame; a winding roller fixed to the winding main shaft; a transmission gear fixed to the winding main shaft; a pressure relief pump meshing with the transmission gear; and an anchor rope connected to the winding roller, one end of which is wound around the winding roller, and the other end connected to a heavy anchor. When the safety house rises due to wind and waves, the anchor rope pulls the winding main shaft to rotate. The pressure relief pump is connected to a hydraulic buffer system to convert the power transmitted by the transmission gear into hydraulic power. When the waves are large, the water level will rise due to the force of the waves, while the heavy anchor remains anchored to the bottom. At this time, the anchor rope will be unwound from the winding roller and pull the winding spindle to rotate. During the rotation of the winding spindle, the transmission gear will rotate synchronously, thereby engaging the pressure relief pump to operate. The pressure relief pump is connected to the hydraulic buffer system to facilitate the flow of fluid, thus converting the power transmitted by the transmission gear into hydraulic power, releasing the energy generated by the waves, achieving a buffering effect, which helps to further improve the safety of the safe house against wind and waves, thereby improving the safety of the safe house.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] like Figures 1 to 3 As shown, this utility model provides a self-adjusting buffer mechanism for a floating safety house 10 to resist wind and waves, including: a support frame 21 set near the four corners of the safety house 10; a winding main shaft 22 rotatably connected to the support frame 21; a winding roller 23 fixed to the winding main shaft 22; a transmission gear 24 fixed to the winding main shaft 22; a pressure relief pump 25 meshing with the transmission gear 24; and an anchor rope 26 connected to the winding roller 23, one end of which is wound around the winding roller 23 and the other end is connected to a heavy anchor 261; when the safety house 10 is raised by wind and waves, the anchor rope 26 pulls the winding main shaft 22 to rotate, and the pressure relief pump 25 is connected to a hydraulic buffer system 30 to convert the power transmitted by the transmission gear 24 into hydraulic power.

[0041] Understandably, the safe house 10 is supported on a floating base 11, which provides buoyancy to float on the water surface and maintain balance. The house of the safe house 10 can usually be formed by splicing together waterproof materials such as aluminum alloy plates, composite plates, and sealed heat insulation plates. Solar photovoltaic panels 54 can usually be laid on the top of the safe house 10 for energy storage and power generation to provide power to the electrical control equipment 53 inside the house.

[0042] Specifically, the support frame 21 includes: flanges 211 located on both sides, and several support rods 212 disposed between the two flanges 211. The anchor rope 26 passes through the gap between the two support rods 212 located below. A heavy-duty low-speed bearing is provided in the middle of the flange 211 to provide a stable rotation platform for the winding spindle 22. The first end of the winding spindle 22 is connected to the transmission gear 24, and the second end extends out of the flange 211 to form a hexagonal or directional manual joint. The manual joint can be turned by turning the support spindle with a special tool. The support rods 212 can guide and block the anchor rope 26, making the winding and unwinding of the anchor rope 26 smoother.

[0043] The take-up roller 23 can be in the form of a plastic roller, rubber roller, etc., and is fixed to the take-up spindle 22 by means of bonding, snapping, etc. In order to make the anchor rope 26 more smoothly take-up and unwind, a take-up groove can be provided on the take-up roller 23. The take-up groove is in the form of a continuous spiral, and the diameter of the take-up groove is similar to the diameter of the anchor rope 26. The distance between the support rod 212 and the take-up roller 23 is set to be slightly smaller than the diameter of the anchor rope 26, thereby preventing the anchor rope 26 from leaving the take-up groove.

[0044] The hydraulic buffer system 30 includes: an oil tank 31 for storing and supplying hydraulic oil; a pressure relief pump 25 connected to the oil tank 31 and pumping hydraulic oil from the oil tank 31 to form hydraulic power; and several interconnected elastic dampers 32, which are connected to the pressure relief pump 25 for receiving hydraulic power to generate elastic buffer deformation. A pressure relief oil passage 33 is also connected between the elastic damper 32 and the oil tank 31. A pressure relief valve 331 is provided on the pressure relief oil passage 33 for opening and releasing pressure after the elastic damper 32 reaches its elastic deformation limit.

[0045] When the pressure relief pump 25 is driven by the transmission gear 24, it pumps hydraulic oil from the oil tank 31 and delivers it to the elastic damper 32 to form hydraulic power. When the elastic damper 32 receives the hydraulic power, it undergoes elastic deformation, thereby releasing the energy generated by the wind and waves and playing a buffering role. However, when the wind and waves are too high, causing the elastic damper 32 to reach its elastic deformation limit, in order to avoid overloading the hydraulic buffer system 30, the pressure relief valve 331 opens when it reaches the opening pressure, and the hydraulic pressure is discharged back into the oil tank 31.

[0046] Furthermore, a first check valve 251 is connected between the pressure relief pump 25 and the elastic damper 32. The first check valve 251 restricts the fluid flow to flow only from the pressure relief pump 25 to the elastic damper 32, and prevents the fluid flow from the elastic damper 32 to the pressure relief pump 25. A second check valve 252 is also connected between the inlet end of the first check valve 251 and the pressure relief pump 25. Specifically, the outlet end of the second check valve 252 is connected to the inlet end of the first check valve 251, and the inlet end of the second check valve 252 is connected to the oil inlet pipe between the oil tank 31 and the pressure relief pump 25. During the rope winding process, the transmission gear 24 will drive the pressure relief pump 25 to reverse, and at this time, the pressure relief valve 331 will idle and circulate through the second check valve 252.

[0047] The elastic damper 32 includes: a damping box 321, with a sealed movable space formed inside; a piston 322 slidably mounted inside and sealed to the damping box 321, which receives hydraulic power; and an elastic reset member 323, with one end connected to the damping box 321 and the other end connected to the piston 322, which generates elastic buffer deformation and is made of spring. Under normal conditions, the piston 322 is positioned at the inlet of the damping box 321 by the action of the elastic reset member 323. When the pressure relief pump 25 pumps hydraulic pressure, it acts on the piston 322, driving the piston 322 to move and compress the elastic reset member 323, forming elastic deformation and achieving a buffering effect. When the water level drops or returns to normal, the pressure relief pump 25 stops pumping hydraulic pressure into the elastic damper 32, at which point the piston 322 stops being stressed and can reset under the elastic force of the elastic reset member 323.

[0048] Furthermore, the transmission gear 24 also meshes with a bidirectional hydraulic motor 40, which is connected to the oil tank 31 and the damping box 321. This motor is used to synchronously depressurize with the pressure relief pump 25 or to drive the winding spindle 22 to rotate in the opposite direction to wind up the anchor rope 26. The displacement of the bidirectional hydraulic motor 40 is smaller than that of the pressure relief pump 25, ensuring that the operation of the bidirectional hydraulic motor 40 does not affect the pressure relief pump 25's depressurization action when the transmission gear 24 rotates forward. The bidirectional hydraulic motor 40 assists in pumping oil while the pressure relief pump 25 is operating, dispersing some of the oil pressure and transmitting it to the elastic damper 32, thus improving the pressure relief buffering effect. When the water level drops or returns to normal, the elastic damper 32 resets, discharging the hydraulic oil and generating hydraulic power for the bidirectional hydraulic motor 40. This drives the bidirectional hydraulic motor 40 to drive the transmission gear 24 to rotate in the opposite direction, which in turn drives the winding spindle 22 to rotate in the opposite direction, rewinding the anchor rope 26 onto the winding roller 23 for the next buffering action.

[0049] Meanwhile, a return oil pipe is connected between the bidirectional hydraulic motor 40 and the oil tank 31. A control valve is connected to the return oil pipe for controlling the return oil flow. The control valve can be an electromagnetic control valve or a manual valve.

[0050] Furthermore, the transmission gear 24 also meshes with a generator 50, which is connected to an energy storage device 51. The transmission gear 24 can mesh with and drive the generator 50 to rotate, generating electrical energy that is stored in the energy storage device 51. Alternatively, the generator 50 can act as a power source to drive the transmission gear 24 to rotate in the opposite direction to reel in the anchor rope 26. It is understood that the generator 50 is an existing self-starting generator. When the transmission gear 24 rotates, it can drive the generator to rotate, generating electrical energy that is stored in the energy storage device 51, thereby effectively utilizing the energy generated by wind and waves, and also assisting in buffering and depressurization. When the driving force of the bidirectional hydraulic motor 40 is insufficient or malfunctions, for example, when the wind and waves are too large and the anchor rope 26 is completely released, the power of the bidirectional hydraulic motor 40 is insufficient to complete the entire reeling action. The generator can be actively controlled to drive the transmission gear 24 to rotate in the opposite direction to reel in the anchor rope 26, ensuring that there is a sufficient length of anchor rope 26 for buffering when the next wind and waves arrive.

[0051] The energy storage device 51 is connected to an energy storage inverter 52, which is used to connect to an electrical control device 53 to provide power. The electrical control device 53 may include, for example, a smart computer, an air conditioner, a communication transceiver, etc. The solar photovoltaic panel 54 is also connected to the energy storage device 51, and the power generated by the solar photovoltaic panel 54 is also stored in the energy storage device 51.

[0052] Meanwhile, in some embodiments, several symmetrically distributed wind turbines 60 can also be provided around the floating base 11 or the safe house 10. For example, they can be arranged in a centrally symmetrical manner on the floating base 11, or in a left-right symmetrical manner on the outside of the safe house 10. The wind turbines 60 can adopt existing generator structures, and the wind turbines 60 are also connected to the energy storage device 51. When the wind on the water surface blows the impeller of the wind turbine 60, the impeller rotates and converts wind energy into electrical energy and stores it in the energy storage device 51, thereby providing power to electrical equipment. At the same time, the rotation of the impeller can also dissipate wind force, which is beneficial to further improve the typhoon resistance performance.

[0053] When this invention is in use, if there are large waves, the water surface will rise due to the force of the waves, while the heavy anchor 261 is anchored to the bottom of the water. At this time, the anchor rope 26 will be unwound from the winding roller 23 and pull the winding main shaft 22 to rotate. During the rotation of the winding main shaft 22, the transmission gear 24 will be driven to rotate synchronously, thereby engaging the pressure relief pump 25 to rotate. The pressure relief pump 25 is connected to the hydraulic buffer system 30 to facilitate the flow of fluid, thereby converting the power transmitted by the transmission gear 24 into hydraulic power, releasing the energy generated by the waves, achieving a buffering effect, which is beneficial to further improve the wave resistance performance of the safety house 10, and thus improve the safety of the safety house 10.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
