Description

Technical Field

[0001] The present application relates to the technical field of utilizing renewable energy for energy production, and in particular to an offshore floating construction device utilizing renewable energy. Background Art

[0002] The world's energy consumption continues to grow, and the resulting environmental pollution problem is becoming increasingly serious. At present, fossil energy is still the world's main energy source. As one of the most abundant renewable resources in nature, seawater has great economic and environmental potential. In recent years, many technical means of using seawater as energy for power generation and salt production have emerged, which not only helps to alleviate the shortage of fresh water and energy, but also provides a new path for environmental protection and sustainable development.

[0003] In the process of utilizing seawater for power generation, hydrogen can be produced from seawater by photocatalysis or electrolysis, and the obtained hydrogen can be used for power generation or stored for standby use. The produced hydrogen is generally sent to an airbag for storage. For example, a floating offshore wind power hydrogen production device with publication number CN116733677B includes a floating platform, a wind power generation device, a water intake device and an electrolysis device, and also includes a hydrogen storage device, which is arranged on the floating platform. The hydrogen storage device includes a plurality of hydrogen storage tanks, and each hydrogen storage tank can be connected to the electrolysis device; a switching turntable, which is connected to the floating platform, and the switching turntable is formed with a connection station, a loading station and a unloading station. The switching turntable can drive each hydrogen storage tank to move to the connection station so as to be connected with the electrolysis device; a locking device, which is arranged between the electrolysis device and the switching turntable; and a conveying platform, which can be detachably connected to the loading station and the unloading station of the floating platform corresponding to the switching turntable, and the conveying platform is formed with a conveying trough, and each hydrogen storage tank can be moved into or removed from the conveying trough of the conveying platform. This prior art facilitates the replacement of hydrogen storage containers, reduces the frequency of transporting hydrogen storage containers, and reduces labor costs.

[0004] However, the above-mentioned prior art still has some defects when producing hydrogen at sea: 1. Due to the corrosiveness of seawater, the external components of the above-mentioned patent application can be anti-corrosive by painting, etc., but its internal components may be damaged during operation, which will cause the device to shut down, thereby interrupting the hydrogen production process and affecting the hydrogen production efficiency; and the above-mentioned patent application cannot be disassembled for transportation when the hydrogen production site is changed, causing the internal components of the device to shake easily due to its large inertia, increasing the risk of damage to the above-mentioned device during transportation.

[0005] 2. Due to the strong winds and waves at sea during the typhoon season, the floating platform of the above patent application is prone to the risk of tipping over at sea, affecting the hydrogen production process of the above patent application.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1 to 13 This application is described in further detail.

[0036] The embodiment of the present application discloses an offshore floating construction device that utilizes renewable energy. The device can be disassembled for easy transportation and the degree of shaking during transportation can be reduced; at the same time, the area of ​​the device on the sea surface can be increased, and the stability of the device during the hydrogen production process can be improved. Embodiment 1:

[0037] See also Figure 1 as well as Figure 2 A floating building device at sea using renewable energy comprises two floating platforms 1 symmetrically distributed on the left and right and having a cylindrical structure. The two floating platforms 1 are connected to each other through a connecting frame 2. The floating platforms 1 are provided with cavities to ensure that the floating platforms 1 float on the sea surface and can temporarily store transitional hydrogen. A plurality of connecting pipes 12 connected to the cavities are evenly installed on the circumferential surface of the floating platform 1. An air bag 13 is installed at one end of the connecting pipe 12 away from the corresponding floating platform 1 for storing hydrogen.

[0038] The upper end surface of the floating platform 1 is evenly penetrated by a plurality of connecting pipes 14 that are connected to the cavity and are used to transport the prepared hydrogen. The upper end surface of the connecting pipe 14 is penetrated by a plurality of capillary channels 141 evenly distributed in the circumference (see Fig.10 ), the seawater is transported upward by capillary action, and the lower end of the connecting pipe 14 passes through the lower end of the floating platform 1, and a photocatalytic chamber 15 with an opening upward is commonly provided on the connecting pipes 14 corresponding to the two floating platforms 1, catalytically decomposing the seawater into hydrogen, and the end of the connecting pipe 14 away from the floating platform 1 passes through the lower end of the photocatalytic chamber 15 and is arranged inside the photocatalytic chamber 15, and the part of the connecting pipe 14 located between the floating platform 1 and the photocatalytic chamber 15 is installed with an on-off valve 16 to control the opening and closing of the connecting pipe 14 and the capillary pipe 141.

[0039] A fixed ring is installed in the middle of the connecting frame 2. During operation, one end of an existing traction rope (not shown in the figure) is fixed to the fixed ring, and the other end of the traction rope is fixed to the coast to ensure that the device will not drift randomly on the sea surface, thereby improving the stability of the device on the sea surface. The opening and closing valves 16 corresponding to the connecting pipes 14 on any side of the floating platform 1 are all closed, and the opening and closing valves 16 corresponding to the connecting pipes 14 on the other side of the floating platform 1 are all opened. Then, the device is placed on the sea surface manually. At this time, seawater is sent into the photocatalytic chamber 15 through the capillary action of the capillary pipe 141. Hydrogen is produced after the seawater is catalyzed by the photocatalytic chamber 15. The hydrogen enters the cavity through the connecting pipe 14. At this time, the hydrogen inside the cavity enters the airbag 13 through the connecting pipe 12.

[0040] After the airbag 13 is inflated, its area on the sea surface can be increased, and at the same time, the buoyancy of the device on the sea surface can be increased, thereby preventing the floating platform 1 from capsizing due to typhoons and improving the stability of the floating platform 1 on the sea surface.

[0041] When the floating platform 1 in working state and its attached parts are damaged due to seawater immersion, the opening and closing valve 16 corresponding to the floating platform 1 in working state is closed, and the opening and closing valve 16 corresponding to the floating platform 1 in non-working state is opened. At this time, the staff can repair the damaged floating platform 1 without stopping the device, thereby improving the hydrogen production efficiency of the device.

[0042] See also Figure 4 A glass plate 151 is provided on the upper end surface of the photocatalytic chamber 15 to facilitate sunlight to enter the interior of the photocatalytic chamber 15. An L-shaped gas outlet pipe 152 is provided above the glass plate 151. Excess hydrogen stored in the air bag 13 is discharged through the gas outlet pipe 152, and the vertical section of the gas outlet pipe 152 passes through the glass plate 151 and is connected to the gas outlet pipe 152. A clamp 153 is installed at the front end of the horizontal section of the gas outlet pipe 152, which is connected to an external power generation device (not shown in the figure).

[0043] After placing the device on the sea surface, the air outlet pipe 152 is connected to the air inlet pipe of the external power generation equipment, and then the air outlet pipe 152 is fixed to the air inlet pipe of the external power generation equipment through the clamp 153. Therefore, the excess hydrogen after being stored in the air bag 13 enters the external power generation equipment through the air outlet pipe 152, thereby ensuring the dynamic balance of the internal air pressure of the device while reducing the waste of hydrogen and improving the efficiency of hydrogen use.

[0044] See also Figure 2 as well as Figure 3 A valve 121 for controlling the opening and closing of the connecting pipe 12 is installed on the circumferential surface of the connecting pipe 12, and a clamp 122 for fixing the airbag 13 is installed at one end of the connecting pipe 12 away from the corresponding floating platform 1.

[0045] During specific operation, when the airbag 13 is full, the staff approaches the floating platform 1, closes the valve 121 of the corresponding connecting pipe 12 and removes the clamp 122 to remove the airbag 13 filled with hydrogen, then puts the new airbag 13 on the corresponding connecting pipe 12, and finally fixes the airbag 13 on the corresponding connecting pipe 12 through the clamp 122.

[0046] See also Figure 5 as well as Figure 6 In order to ensure that seawater can smoothly enter the interior of the photocatalytic chamber 15 and avoid the situation where the seawater tension is small and cannot completely enter the interior of the photocatalytic chamber 15 through capillary action, a transition pipe 142 matching the inner wall of the connecting pipe 14 is installed at the lower end of the connecting pipe 14 of the present invention. The hydrogen inside the connecting pipe 14 enters the cavity through the transition pipe 142. The end of the transition pipe 142 away from the connecting pipe 14 is connected to the interior of the corresponding floating platform 1. An annular pipe 143 connected to the capillary pipe 141 is installed at the lower end surface of the connecting pipe 14. The annular pipes 143 corresponding to the same floating platform 1 are connected through a transition connecting pipe 144. A water pump 145 matching the transition connecting pipe 144 is installed at the lower end surface of the floating platform 1 for pumping seawater into the transition connecting pipe 144.

[0047] During specific operation, the transition pipe 144 is connected to the water pump 145 on the same side. When the seawater inside the photocatalytic chamber 15 is insufficient for hydrogen production, the airbag 13 no longer expands. At this time, the water pump 145 is turned on to suck in seawater and pump the seawater into the photocatalytic chamber 15 through the transition pipe 142, the annular pipe 143 and the capillary tube 141 in turn, so as to avoid insufficient seawater supply affecting the photocatalytic efficiency of seawater.

[0048] See also Figure 7 as well as Fig.13 In order to reduce the possibility of hydrogen leakage caused by failure of external power generation equipment or blockage inside the outlet pipe 152, a solenoid valve 154 is installed on the front side of the horizontal section of the outlet pipe 152 of the present invention to control the opening and closing of the outlet pipe 152. An electronic pressure gauge 155 and a transition bag 156 are respectively installed on the horizontal section of the outlet pipe 152 and on the front and rear sides of the solenoid valve 154. The solenoid valve 154 and the electronic pressure gauge 155 are interconnected through a central control component.

[0049] The central control assembly includes a central control panel arranged on the air outlet pipe 152, buttons arranged on the central control panel, and a central control unit arranged inside the central control panel, wherein the central control unit includes a central control module, a button control module electrically connected to the central control module, a pressure sensor module electrically connected to the central control module, and a valve control module electrically connected to the central control module; The pressure sensing module is electrically connected to the electronic pressure gauge 155 , the valve control module is electrically connected to the solenoid valve 154 , and the key control module is electrically connected to the key.

[0050] During specific operation, the button is turned on, and the button control module receives the signal from the button and transmits the received signal to the central control module. At this time, the central control module is turned on. When the external power generation equipment fails and causes the outlet pipe 152 to be blocked or leaked, the electronic pressure gauge 155 sends a signal and transmits it to the pressure sensing module. The pressure sensing module transmits the received signal to the central control module. The central control module analyzes and processes the received signal and then transmits it to the valve control module. The valve control module transmits the received signal to the solenoid valve 154 after processing. At this time, the solenoid valve 154 is closed, and the outlet pipe 152 is in a closed state. At this time, excess hydrogen in the outlet pipe 152 enters the transition bag 156, thereby dynamically balancing the air pressure inside the device to avoid the risk of damage to the device or even explosion caused by excessive hydrogen pressure inside the device.

[0051] The external power generation equipment can be repaired by the staff. When the external power generation equipment is repaired, the outlet pipe 152 is connected to the air inlet pipe of the external power generation equipment again. At this time, the staff opens the solenoid valve 154, and the hydrogen inside the transition bag 156 enters the external power generation equipment through the outlet pipe 152.

[0052] See also Fig. 9 as well as Fig.10 The left and right ends of the connecting frame 2 are respectively connected to the floating platform 1 on the same side, and the floating platform 1 is screwed with fastening bolts 21 for fixing the connecting frame 2 (see Figure 1 ), the portion of the circumferential surface of the connecting tube 14 located outside the photocatalytic chamber 15 is provided with a supporting protrusion 146 for supporting the photocatalytic chamber 15, and the portion of the circumferential surface of the connecting tube 14 located inside the photocatalytic chamber 15 is provided with a limiting protrusion 147 that cooperates with the supporting protrusion 146 in a detachable manner, and the connecting tube 12 is installed on the floating platform 1 by a threaded connection.

[0053] A rubber pad (not shown in the figure) is installed between the connecting pipe 12 and the floating platform 1 to increase the air tightness between the connecting pipe 12 and the internal cavity of the floating platform 1. When the device needs to be transported after the hydrogen production is completed, the towing rope is removed from the shore and removed from the fixed ring, and then the fastening bolts 21 are removed to remove the connecting frame 2 from the floating platform 1, and then the limiting protrusions 147 are removed to remove the photocatalytic chamber 15 from the connecting pipe 14, and then the connecting pipe 12 is removed from the floating platform 1. Therefore, the above-mentioned components are connected to each other in a detachable manner, and then the device can be disassembled as a whole when the device is transferred, thereby avoiding the possibility of shaking of the internal components of the device due to the inertia of the device, and reducing the risk of damage to the above-mentioned device during transportation. Embodiment 2:

[0054] See also Fig.11 as well as Fig.12 On the basis of Example 1, since the evaporation of seawater during photocatalysis may cause impurities in the seawater to float on the glass plate 151, and at the same time, the evaporated water droplets are prevented from adhering to the glass plate 151 and affecting the effect of sunlight irradiating into the photocatalytic chamber 15, a moving block 1501 that is symmetrical front and back and can move left and right is arranged inside the photocatalytic chamber 15 of the present invention, and the front and rear moving blocks 1501 are respectively slidably arranged on the inner wall of the photocatalytic chamber 15, and a rotating shaft 157 extending up and down is rotatably installed on the moving block 1501 through a bearing, and the rotating shaft 157 is located on the upper side of the moving block 1501 on the same side, and a pulley 158 is installed, and a belt 159 is installed between the two pulleys 158, and a cleaning sponge 150 is installed on the belt 159 to clean the glass plate 151.

[0055] A gear 1571 is installed on the rear rotating shaft 157 and located at the lower side of the moving block 1501 on the same side, and a rack plate 1572 meshing with the gear 1571 is installed on the inner wall of the rear side of the photocatalytic chamber 15.

[0056] During specific operation, the moving block 1501 is driven to move back and forth left and right through an external driving force (electric slider, etc.). During the movement of the moving block 1501, the rack plate 1572 cooperates with the gear 1571 to drive the rear rotating shaft 157 to rotate. During the rotation of the rotating shaft 157, the rear pulley 158 is driven to rotate. During the rotation of the rear pulley 158, the front pulley 158 is driven to rotate through the belt 159. At this time, the belt 159 moves on the two pulleys 158. During the movement of the belt 159, the cleaning sponge 150 can be used to wipe the impurities and water droplets attached to the glass plate 151, thereby ensuring that the external sunlight can smoothly enter the interior of the photocatalytic chamber 15, thereby improving the catalytic hydrogen production effect of seawater.

[0057] The implementation principle of the present invention is: (1) All the opening and closing valves 16 corresponding to the connecting pipes 14 on any one side of the floating platform 1 are closed, and all the opening and closing valves 16 corresponding to the connecting pipes 14 on the other side of the floating platform 1 are opened, and then the device is placed on the sea surface manually. At this time, seawater is sent into the photocatalytic chamber 15 through the capillary action of the capillary tube 141. Hydrogen is produced after the seawater is catalyzed by the photocatalytic chamber 15. The hydrogen enters the cavity through the connecting pipe 14. At this time, the hydrogen inside the cavity enters the airbag 13 through the connecting pipe 12.

[0058] (2) The staff approaches the floating platform 1, closes the valve 121 of the corresponding connecting pipe 12, removes the clamp 122, removes the airbag 13 filled with hydrogen, and then puts a new airbag 13 on the corresponding connecting pipe 12. Finally, the airbag 13 is fixed to the corresponding connecting pipe 12 by the clamp 122.

[0059] (3) At this time, the button control module receives the signal sent by the button and transmits the received signal to the central control module. At this time, the central control module is turned on. When the external power generation equipment fails and causes the outlet pipe 152 to be blocked or leaked, the electronic pressure gauge 155 sends a signal and transmits it to the pressure sensing module. The pressure sensing module transmits the received signal to the central control module. The central control module analyzes and processes the received signal and transmits it to the valve control module. The valve control module transmits the received signal to the solenoid valve 154 after processing. At this time, the solenoid valve 154 is closed, and the outlet pipe 152 is in a closed state. At this time, excess hydrogen in the outlet pipe 152 enters the interior of the transition bag 156.

[0060] (4) When the device needs to be transported after hydrogen production is completed, the towing rope is removed from the shore and removed from the fixed ring, and then the fastening bolts 21 are removed to remove the connecting frame 2 from the floating platform 1, and then the limiting protrusions 147 are removed to remove the photocatalytic chamber 15 from the connecting pipe 14, and then the connecting pipe 12 is removed from the floating platform 1.
