Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples. Furthermore, various embodiments or examples and features of different embodiments or examples described in this specification can be combined and combined by one skilled in the art without contradiction.
Referring to fig. 1 to 42, the fluid kinetic energy conversion device according to the embodiment of the present invention includes a plurality of interacting power conversion assemblies, each of which includes a plurality of guide rails 4, a roller blind assembly 2, a chain belt 1 and a plurality of energy storage assemblies.
The guide rails 4 are arranged in the river channel. As shown in fig. 2 and 3, the number of the guide rails 4 may be four, thereby forming a moving space of the roll screen assembly 2 between the four guide rails 4. Of course, the number and distribution of the guide rails 4 is not limited to the examples given herein, and will depend on the structure of the roller blind body 202 in the roller blind assembly 2 and other relevant factors. For example, six, eight or any other number of guide rails 4 may be adopted, as long as the installation requirement of the roller shutter assembly 2 is met, and the roller shutter assembly 2 can be installed in the river channel through the guide rails 4, so as to utilize the kinetic energy of the fluid in the river channel. Further, the structure and material of the guide rail 4 are not particularly required. Of course, since the guide rail 4 is provided in the river course, the guide rail 4 may be made of a rust-proof material as much as possible.
The roller blind assembly 2 is mounted to the guide rail 4 and is movable in either a forward or reverse direction along the length of the guide rail 4. Wherein the length direction of the guide rail 4 corresponds to the extending direction of the river runner. The guide rail 4 may have a linear structure or a curved structure. In order to ensure that the structure of the fluid kinetic energy conversion equipment is simple, the fluid kinetic energy conversion equipment is installed by selecting a straight line section or an approximate straight line section of a river channel as much as possible, and the guide rail 4 is also selected to have a straight line structure as much as possible.
The rolling shutter assembly 2 includes a roller 201 and a shutter body 202 adapted to be retracted and extended as the roller 201 rotates. The rolling curtain body 202 is generally in the form of a flexible rolling curtain plate or a rolling curtain cloth for rolling. Of course, the specific form of the rolling shutter body 202 is not limited as long as the rolling shutter body 202 can be wound and unwound along with the rotation of the winding shaft 201. Because the roller shutter assembly 2 is installed in the river channel, the roller shutter body 202 will be subjected to a certain buoyancy when unreeling. In order to ensure that the roller shutter assembly 2 is smoothly unreeled, the roller shutter assembly 2 may be made of a material having a density greater than that of water, and the bottom of the roller shutter assembly 2 may also be a tensioning structure, wherein the tensioning structure is described in detail below.
The chain belt 1 is connected with the roller shutter component 2. The chain belt 1 is used for driving the roller blind assembly 2 moving towards the downstream end of the guide rail 4 to move downstream in an unreeling state (including completely unreeling or not completely unreeling), or the chain belt 1 is used for driving the roller blind assembly 2 moving towards the upstream end of the guide rail 4 in a reeling state (including completely reeling or not completely reeling). The downstream end part of the guide rail 4 refers to the end part of the guide rail 4 corresponding to the downstream of the river runner; the upstream end of the guide rail 4 refers to the end of the guide rail 4 corresponding to the upstream of the river channel, wherein "upstream" and "downstream" are only relative concepts for the river channel. When the roller blind assembly 2 moves from upstream to downstream along the fluid in the river channel, the roller blind assembly 2 can drive the chain belt 1 to move towards the downstream end of the guide rail 4. When the roller blind assembly 2 is to move from downstream to upstream against the fluid, the chain belt 1 drives the roller blind assembly 2 to move towards the upstream end of the guide rail 4, and the power of the chain belt 1 is derived from the power conversion assembly which moves the other roller blind assembly 2 along the fluid. The chain belt 1 refers to a chain or a conveyor belt that can be engaged with a gear structure.
A plurality of first gears 3 engaged with the chain belt 1 are provided along the chain belt 1. Several energy storage assemblies are power coupled to the first gear 3 to store kinetic energy of the first gear 3. When the first gear 3 adopts a structural form of a belt wheel, the chain belt 1 refers to a conveying belt capable of being matched with the belt wheel; when the first gear 3 is in the form of a common gear, the chain belt 1 is a chain that can cooperate with the common gear. The chain belt 1 is generally disposed in a ring shape, and in this case, the moving direction of the chain belt 1 refers to the moving direction of the section of the chain belt 1 connected to the roller blind assembly 2. It should be noted that many first gears 3 are not shown, and the arrangement of the first gears 3 along the chain belt 1 may be determined according to the requirement. For example, the first gear 3 may be provided at a position where kinetic energy of the fluid is to be extracted; for another example, the first gear 3 may be disposed at a position corresponding to the first gravity energy storage assembly 6 and the second gravity energy storage assembly 7 mentioned later.
A gear set 5 is provided between the chain belts 1 of the interacting power conversion assemblies. Wherein the roller blind assembly 2 of the downstream roller blind assembly 2 drives the roller blind assembly 2 of the other power conversion assembly interacting with each other to reverse flow through the gear set 5. Of course, besides the gear set 5, other transmission components can be obviously arranged between the chain belts 1 of the power conversion assemblies which interact with each other. The chain belts 1 of the interacting power conversion assemblies move toward the upstream and downstream ends of the guide rails 4, respectively. In fig. 1, the chain belt 1 is in a rectangular ring shape and includes four chain belt sections 1 connected end to end, and the moving direction of the chain belt 1 is hereinafter referred to as the moving direction of the bottom chain belt section (i.e., the chain belt section connected with the roller blind assembly 2) for convenience of description. As shown in fig. 1, assuming that the interactive power conversion assemblies include a first power conversion assembly a and a second power conversion assembly B (of course, the interactive power conversion assemblies may be three or more, and only two interactive power conversion assemblies are described below as an example), the roller blind assembly 2 of the first power conversion assembly a moves from the upstream to the downstream of the river channel under the action of the fluid, and then the roller blind assembly 2 drives the chain belt 1 of the first power conversion assembly a to move toward the downstream end portion a2 of the guide rail 4. The chain belt 1 of the first power conversion assembly a drives the chain belt 1 of the second power conversion assembly B through the gear set 5, so that the chain belt 1 of the second power conversion assembly B moves towards the upstream end a1 of the guide rail 4, and the chain belt 1 can drive the roller shutter assembly 2 to move towards the upstream end of the guide rail 4. The rolling curtain component 2 moving along the fluid is in an unreeling state, and the rolling curtain component 2 moving against the fluid is in a reeling state, so that for the power conversion components with multiple interactions, the thrust of the fluid on one rolling curtain component 2 is far greater than the resistance of the fluid on the other rolling curtain component 2, and the rolling curtain components 2 with multiple interactions are wholly subjected to the thrust along the fluid to convert the kinetic energy of the fluid, wherein the conversion of the kinetic energy of the fluid comprises the condition of storing the kinetic energy of the fluid firstly and the condition of directly utilizing the kinetic energy of the fluid, namely, the energy storage component can temporarily store the kinetic energy of the fluid and can directly utilize the kinetic energy of the fluid.
Any other transmission components can be arranged between the interacting multiple sets of power conversion assemblies besides the gear set 5, and the position relationship between the multiple sets of power conversion assemblies can be determined. For example, multiple sets of power conversion assemblies may be arranged side by side in the river channel, that is, multiple sets of power conversion assemblies are distributed along the width direction of the river channel. Or, multiple sets of power conversion assemblies may be arranged along the length direction of the river channel, and in this case, the downstream end of the chain belt 1 of the first power conversion assembly a and the upstream end of the second power conversion assembly B are power coupled through the gear set 5. For the first power conversion assembly a and the second power conversion assembly B, assuming that the roller blind assembly 2 of the first power conversion assembly a moves toward the downstream, the roller blind assembly 2 of the second power conversion assembly B moves toward the upstream, and the chain belt 1 of the first power conversion assembly a powers the reverse flow movement of the second power conversion assembly B through the gear set 5; on the contrary, assuming that the roller blind assembly 2 of the first power conversion assembly a moves toward the upstream, the roller blind assembly 2 of the second power conversion assembly B moves toward the downstream, and the chain belt 1 of the second power conversion assembly B powers the reverse flow movement of the first power conversion assembly a through the gear set 5.
According to the fluid kinetic energy conversion equipment provided by the embodiment of the utility model, the energy of the fluid in the river channel is stored through various interactive power conversion assemblies, so that the fluid kinetic energy in nature can be utilized. Wherein for each set of power conversion assemblies: the conversion of the kinetic energy of the fluid can be realized when the roller blind assembly 2 moves along the guide rail 4 from the upstream end to the downstream end; when the roller blind assembly 2 moves to the downstream end, the chain belt 1 of the other power conversion assembly interacting at this time drives the chain belt 1 of the current power conversion assembly through the gear set 5, so that the roller blind assembly 2 moves to the upstream end of the guide rail 4 again for the next conversion of the fluid kinetic energy. The fluid kinetic energy conversion equipment does not need to be provided with a high dam for water storage and energy storage. In addition, because guide rail 4, roll up curtain subassembly 2 and energy storage subassembly etc. can design based on the interface size of river runner, and then can guarantee not to influence the normal use of river runner. For example, the passage of ships in river channels or the swimming of fishes and shrimps and the like can not be influenced by the fluid kinetic energy conversion equipment.
According to the fluid kinetic energy conversion equipment provided by the embodiment of the utility model, the guide rail 4 is designed into a straight line section, and the river channel of the straight line section is selected as far as possible correspondingly. The length of the guide rail 4 can be selected by the conditions of the river channel. For example, the length of the guide rail 4 may be about 5 meters, or may be much longer than 5 meters (e.g., 20 meters, 30 meters, 50 meters or even longer), and a plurality of first gears 3 engaged with the chain belt 1 may be disposed along the length of the guide rail 4. Thereby, the fluid kinetic energy can be extracted through any first gear 3 to achieve the maximum conversion of the fluid kinetic energy.
According to the embodiment of the utility model, the energy storage assembly comprises a gravity energy storage assembly, wherein the gravity energy storage assembly comprises a first gravity energy storage assembly 6 arranged corresponding to the upstream end part and a second gravity energy storage assembly 7 arranged corresponding to the downstream end part; the first gravity energy storage assembly 6 is used for driving the scroll 201 to unreel under the action of one of the first gears 3, and the second gravity energy storage assembly 7 is used for driving the scroll 201 to reel under the action of the other one of the first gears 3. At the moment, the rolling and the unreeling of the roller shutter assembly 2 in the fluid kinetic energy conversion equipment are realized through the conversion of the fluid kinetic energy, and other control parts do not need to be additionally arranged. Of course, the roller shutter assembly 2 with an automatic lifting effect can be arranged, so that the roller shutter assembly 2 can be automatically unwound when moving to the upstream end part and can be automatically wound when moving to the downstream end part. Wherein, for the roller blind assembly 2 with automatic lifting effect, it can set a sensor at the relevant position of at least one of the guide rail 4, the roller blind assembly 2 and the chain belt 1, and then sense the position of the roller blind assembly 2 through the sensor, and control the roller blind assembly 2 to automatically lift based on the position of the roller blind assembly 2.
According to the embodiment of the utility model, in the case of the first gravity energy storage assembly 6 and the second gravity energy storage assembly 7, the power conversion assembly further comprises a clutch component 9, namely a first clutch component corresponding to the first gravity energy storage assembly 6 and a second clutch component corresponding to the second gravity energy storage assembly 7.
That is, under the condition that the first gear 3 drives the reel 201 to unreel through the first gravity energy storage assembly 6, the first clutch component is disposed corresponding to the first gravity energy storage assembly 6, and is configured to couple the first gravity energy storage assembly 6 and the first gear 3 corresponding thereto in the process that the roller shutter assembly 2 moves toward the upstream end along the guide rail 4, and disengage the first gear 3 and the first gravity energy storage assembly 6 when the roller shutter assembly 2 reaches the upstream end, so that the first gravity energy storage assembly 6 drives the reel 201 to unreel. That is, through the effect of the first clutch component, it can be ensured that the kinetic energy of the first gear 3 is converted into the gravitational potential energy of the first gravitational energy storage assembly 6, and the gravitational potential energy of the first gravitational energy storage assembly 6 is used for driving the reel 201 to rotate so as to realize unreeling. Wherein, the first gravity energy storage assembly 6 and the corresponding first gear 3 can be coupled in the process that the roller blind assembly 2 is positioned near the upstream end of the guide rail 4 and starts to move towards the downstream end, so that the energy storage can be realized in the process that the roller blind assembly 2 moves from the downstream end to the upstream end next time. When the roller blind assembly 2 starts to move from the upstream end to the downstream end along the guide rail 4, referring to fig. 7, since the corresponding first gear 3 is in the form of a one-way ratchet (refer to fig. 32 and 33), the first gravity energy storage assembly 6 is not driven to move during the downward movement of the roller blind assembly 2; when only the roller shutter component 2 moves up in the reverse direction, the first gear 3 corresponding to the first clutch component can drive the first gravity energy storage component 6 to store energy.
Similarly, the first gear 3 can also drive the reel 201 to wind through the second gravity energy storage assembly 7. And, at this time, the power conversion assembly further comprises a second clutch component arranged corresponding to the second gravity energy storage assembly 7, the second clutch component is suitable for dynamically coupling the second gravity energy storage assembly 7 and the first gear 3 corresponding to the second gravity energy storage assembly 7 in the process that the roller shutter assembly 2 moves towards the downstream end part along the guide rail 4, and in the case that the roller shutter assembly 2 reaches the downstream end part, the first gear 3 and the second gravity energy storage assembly 7 are disengaged, so that the second gravity energy storage assembly 7 drives the roller 201 to wind. During the process when the rolling shutter assembly 2 is near the downstream end and starts to move towards the upstream end, the second clutch component can be triggered to be in power coupling with the second gravity energy storage assembly 7. However, during the movement of the rolling shutter assembly 2 toward the upstream end, the second gravitational energy storage assembly 7 does not move because it employs a one-way ratchet mechanism (refer to fig. 32 and 33) as shown in fig. 7 corresponding to the first gear 3 of the second gravitational energy storage assembly 7.
The clutch member 9 may adopt an automatic clutch, and the clutch member 9 may switch positions based on the position of the roller shutter assembly 2, and of course, the clutch member 9 may also be controlled by the first stroke control assembly. Specifically, the power conversion assembly further comprises a first stroke control assembly, the first stroke control assembly is mounted on the chain belt 1 or the roller shutter assembly 2, and the first stroke control assembly moves along with the chain belt 1 or the roller shutter assembly 2. For controlling the clutch member 9 to switch between the coupled or uncoupled position in case the first stroke control assembly is moved to the position of the clutch member 9.
Referring to fig. 3 and 6 to 8, the first stroke control assembly includes two first wedge-shaped members 10, the first wedge-shaped members 10 are mounted to the roll screen assembly 2, and the first wedge-shaped members 10 are formed with first wedge faces 101 as the roll screen assembly 2 moves. Furthermore, the clutch member 9 includes a second gear 901, two racks 902, a third wedge 904, and a third gear 906. Two racks 902 are located on two sides of the second gear 901 and perform reverse linear motion, that is, when one rack 902 moves downward, the other rack 902 moves upward, and vice versa. A first bearing 907 is installed at the first end of the rack 902, and the first bearings 907 at the first ends of the two racks 902 are matched with the first wedge-shaped surfaces 101 of the two first wedge-shaped pieces 10 respectively and do linear motion under the action of the first wedge-shaped surfaces 101; a second end of the rack 902 is provided with a second wedge 903, and the second wedge 903 is formed with a second wedge surface 9031; the third wedge 904 is formed with a third wedge surface 9041 matched with the second wedge surface 9031, the third wedge 904 is connected with the first gear 3 through a transmission shaft 905, and the first gear 3 can only drive the third wedge 904 to rotate towards a set direction, that is, the transmission shaft 905 and the first gear 3 rotate in a unidirectional and synchronous manner. The cooperation between the second wedge surface 9031 and the third wedge surface 9041 can drive the third wedge 904 to move. The third wedge 904 has a coupled position and a disengaged position. In the coupled position, the first gear 3 is connected to the third gear 906 via the transmission shaft 905; in the disengaged position, the first gear 3 may be coupled to the drive shaft 905, but the drive shaft 905 disengages from the third gear 906 as the third wedge 904 moves, such that the first gear 3 and the third gear 906 are independent of each other.
The first wedge-shaped member 10 may be provided with a mounting hole 102, and the first wedge-shaped member 10 may be mounted to the blind assembly 2 by a mounting member mounted through the mounting hole 102. The installation angle of the first wedge-shaped element 10 can be adjusted by the arrangement of the through-fitting element, so that the cooperation between the first wedge surface 101 and the rack 902 is ensured.
It will be seen from fig. 1 to 5 that each first stroke control assembly comprises two oppositely directed first wedge parts 10, the two first wedge parts 10 of which are arranged one behind the other. One of the first wedge members 10 in the first travel control assembly may then interact with one of the racks 902 of FIG. 7 to control the drive shaft 905 to connect with the third gear 906; another first wedge-shaped element 10 can interact with another rack 902 in fig. 7 to control the disengagement of the drive shaft 905 from the third gear 906. Of course, the position relationship of the two first wedge-shaped pieces 10 is not limited by the drawings, as long as in the process of moving along with the roller blind assembly 2 and the chain belt 1, the two first wedge-shaped pieces can be respectively matched with the racks 902 on the two sides of the second gear 901 at different times so as to drive the clutch component to realize state switching. The gravity energy storage assembly comprises a vertical rod 601 and a weight member 602. Wherein, the weight member 602 is installed on the vertical rod 601, and the weight member 602 can be lifted along the vertical rod 601. The weight 602 refers to any structure that has a certain gravity and can be lowered to drive the roller blind assembly 2 to wind or unwind when the clutch member 9 is in the disengaged position. Wherein the weight 602 is provided with a first tooth segment 60221 and a second tooth segment 60222 that lie in different planes. The first gear segment 60221 is disposed in correspondence with the third gear 906, and the second gear segment 60222 is power coupled to the spool 201 via the unidirectional transmission assembly 16.
In fig. 8, the second tooth segment 60222 and the first tooth segment 60221 have different tooth profiles. Wherein the first tooth segment 60221 is denser and the second tooth segment 60222 is more comb. As the roller shade assembly 2 moves along one end of the guide rail 4 to the other, the third gear 906 moves from the bottom end to the top end of the first gear segment 60221; as the weight 602 moves from the upper limit position to the lower limit position of the vertical bar 601, the winding/unwinding of the winding shaft 201 is completed. The weight member 602 includes upper and lower weights 6021 and a faceted column gear rack 6022 positioned between the two weights 6021, the faceted column gear rack 6022 formed with a first gear segment 60221 and a second gear segment 60222.
Under the condition that the transmission shaft 905 is coupled with the third gear 906, the first gear 3 drives the weight 602 to ascend through the transmission shaft 905 and the third gear 906; when the transmission shaft 905 is disengaged from the third gear 906, the weight 602 descends to drive the winding shaft 201 to unwind or wind.
Specifically, when the first gear 3 is coupled to the third gear 906 via the clutch component 9, the first gear 3 can drive the third gear 906 to rotate, and when the third gear 906 rotates, the third gear is engaged with the first tooth segment 60221, so that the weight 602 rises along the vertical rod 601. The process weight 602 stores gravitational potential energy. When the rolling shutter assembly 2 moves to the upstream end of the guide rail 4, the first gear 3 and the third gear 906 are disengaged, and at this time, under the action of the gravity of the weight 602, the weight 602 descends to drive the one-way transmission assembly 16 to move, so as to drive the winding shaft 201 to wind or unwind.
Since the first clutch component of the first gravity energy storage assembly 6 and the first stroke control assembly work in a similar manner to the second clutch component of the second gravity energy storage assembly 7 and the second stroke control assembly, only the first clutch component of the first gravity energy storage assembly 6 and the first stroke control assembly will be described as an example. Specifically, when one of the first wedge members 10 of the first stroke control assembly of the first gravity energy storage assembly 6 is located near the upstream end of the guide rail 4 and moves from the upstream end to the downstream end, at this time, the first wedge member 10 acts on the left rack 902 of the first clutch part in fig. 7, the left rack 902 moves downward and drives the second gear 901 to rotate counterclockwise, and the second gear 901 rotates counterclockwise and drives the right rack 902 to move upward. Meanwhile, the second wedge 903 connected to the left rack 902 has the second wedge surface 9031 acting on the third wedge surface 9041 on the left side of the third wedge 904, so that the third wedge 904 moves to the right, at this time, the transmission shaft 905 is coupled to the third gear 906, so that the clutch component 9 is in a coupled state when the next roller shutter assembly 2 moves from the downstream end to the upstream end, and the first gear 3 can drive the first gravity energy storage assembly 6 to store energy.
When the first stroke control assembly of the first gravity energy storage assembly 6, the other first wedge 10 moves towards the upstream end of the guide rail 4 along with the roller blind assembly 2 and is near the upstream end, at this time, the first wedge 10 acts on the right rack 902 of the first clutch part, the right rack 902 moves downwards and drives the second gear 901 to rotate clockwise, and the second gear 901 rotates clockwise and drives the left rack 902 to move upwards. Meanwhile, the second wedge surface 9031 of the second wedge 903 connected to the right rack 902 acts on the third wedge surface 9041 on the right side of the third wedge 904, so that the third wedge 904 moves to the left, and the transmission shaft 905 and the third gear 906 are disengaged at this time, so that the first gravity energy storage assembly 6 drives the roller blind assembly 2 at the upstream end to unwind under the action of gravity.
According to an embodiment of the present invention, the fluid kinetic energy conversion device further comprises a stopper assembly 8. The stopping assembly 8 is switched between a locking position and an unlocking position based on the starting and stopping of the unreeling, and before the unreeling is started, the stopping assembly 8 is switched to the locking position to lock the roller shutter assembly 2 at the upstream end part; after unwinding, the stop assembly 8 is switched to the unlocking position to avoid the roller blind assembly 2, so that the roller blind assembly 2 can move towards the downstream end along with the fluid.
The stop assembly 8 here can be an automatic control assembly, i.e. the position and state of the roller blind assembly 2 can be detected based on the setting of the sensor. Specifically, when the sensor detects that the roller blind assembly 2 moves to the upstream end, the stop assembly 8 may be controlled to rotate based on the detection result, so that the stop assembly 8 is switched to the locking position to lock the roller blind assembly 2 at the current position; when the sensor detects that the roll screen assembly 2 is at the upstream end and the roll screen body 202 is completely unwound, the stop assembly 8 may be controlled to rotate based on the detection result, so that the stop assembly 8 is switched to the unlocking position, and the roll screen assembly 2 after the unwinding is completed may move downstream again along with the fluid. The stop assembly 8 serves to prevent the roller blind assembly 2 from moving downstream under fluid flushing before unwinding is complete. Moreover, only when the roller shutter is fully unwound, the contact area between the roller shutter body 202 and the fluid can be larger, and further, the kinetic energy of the fluid can be utilized to a greater extent.
Of course, the stop assembly 8 may also control the switch position by means of a second and a third stroke control assembly. Specifically, the roller shutter body 202 is provided with a second stroke control assembly, and when unwinding is completed, the second stroke control assembly controls the stopping assembly 8 to be switched from the locking position to the unlocking position; the roller shutter assembly 2 is provided with a third travel control assembly, the third travel assembly is installed on the chain belt 1 or the roller shutter assembly 2 and is suitable for moving along with the chain belt 1 or the roller shutter assembly 2, and the third travel control assembly is suitable for controlling the stop assembly 8 to be switched to an unlocking position from a locking position before unwinding starts. In this case, the position switching of the stopper assembly 8 can be directly determined by the roller blind assembly 2 or the chain belt 1 under the action of the fluid kinetic energy without additionally providing a power source.
The second and third travel control assemblies may be configured with reference to the first wedge 10, rack 902, and second gear 901 configurations described above. In particular, the first wedge 10 of the second stroke control assembly is formed with a first wedge surface which acts on a rack 902 (with reference to the construction of the clutch member 9) on one side of the second gear 901. When the rack 902 drives the second gear 901 to rotate forward, the second gear 901 can drive the fourth gear 803 of the stopping assembly 8 to rotate forward. Likewise, the wedge face of the first wedge 10 of the third stroke assembly may act on the rack 902 on the other side of the second gear 901. When the rack 902 drives the second gear 901 to rotate reversely, the second gear 901 can drive the fourth gear 803 of the stopping assembly 8 to rotate reversely.
In fig. 9-11, the stop assembly 8 includes a gravity balance 801, a latch 802, a fourth gear 803, and a spud 804. The gravity balance 801, the latch 802, and the latch 802 are all mounted to the peg 804 and may rotate about the peg 804. When the wedge surface of the second stroke control assembly drives the fourth gear 803 to rotate forward, the fourth gear 803 drives the gravity balance member 801 to rotate, and further the lock bolt 802 can be driven to rotate to the locking position only by a small external force, referring to fig. 5, the locking position of the lock bolt 802 corresponds to the locking position of the stopper assembly 8, that is, the stopper assembly 8 is locked by the lock bolt 802. When the wedge surface of the third stroke control assembly drives the fourth gear 803 to rotate in the opposite direction, the fourth gear 803 drives the gravity balance member 801 to rotate, and similarly, a small external force is required to drive the lock bolt 802 to rotate to the unlocking position, referring to fig. 4, the unlocking position of the lock bolt 802 corresponds to the unlocking position of the stop assembly 8. The latch 802 may be locked or unlocked by turning 90 or any other angle.
According to an embodiment of the present invention, the fluid kinetic energy conversion apparatus further includes a mesh enclosure 12, the mesh enclosure 12 being formed with an installation space in which the plurality of sets of power conversion components are installed. The mesh enclosure 12 is used to prevent external impurities from entering the installation space, and to avoid affecting the normal operation of the power conversion assembly. For example, the mesh enclosure 12 includes a front mesh 121 and a side mesh 122. Wherein, the front protecting net 121 is installed at the upstream of the power conversion assembly in the river runner. The front protecting net 121 can be designed to be arc-shaped, so that sundries flowing through the front protecting net 121 can be guided to a certain extent, and the sundries can flow to two sides along the arc-shaped front protecting net 121. On this basis, the side protecting net 122 can further protect the power conversion assembly and avoid the sundry basic power conversion assembly.
In fig. 12, the front guard net 121 is higher than the side guard nets 122. Of course, the side panels 122 may be designed to be as tall as the front panel 121.
According to the embodiment of the present invention, the power conversion assembly further includes the net frame 14, the net frame 14 is located at the downstream of the rolling shutter body 202, and the accommodating space 1401 of the rolling shutter body 202 is formed, and when the unwinding is completed, the rolling shutter body 202 is located in the accommodating space 1401. In this case, through the setting of the net frame 14, the structure of the rolling curtain body 202 can be strengthened, and the rolling curtain body 202 is prevented from deforming or even being damaged under the impact of the fluid. Also, since fluid can normally pass through the frame 14, the frame 14 is not positioned to interfere with the movement of the roller shade assembly 2. The material of the frame 14 is selected to ensure a certain structural strength. Furthermore, the frame 14 is not so fine as to prevent excessive resistance to the movement of the frame 14 and the roller blind assembly 2 together against the fluid in the event of a roll-up. In order to move the screen frame 14 and the rolling shutter assembly 2 together, the roller 201 of the rolling shutter assembly 2 may be mounted to the edge of the screen frame 14. Of course, other manners of engagement of the frame 14 and the roller shade assembly 2 are possible. Of course, in the case where the strength of the rolling shutter body 202 is sufficient, the frame 14 may not be provided.
In the case where the screen frame 14 is provided, the screen frame 14 is mounted to the guide rail 4, and the roll screen assembly 2 is mounted to the screen frame 14, and the roll screen assembly 2 is moved along the guide rail 4 by the screen frame 14. In order to ensure the smooth movement of the screen frame 14 along the guide rail 4, a sliding assembly 13 may be installed at the edge of the screen frame 14. Referring to fig. 13 and 14, the sliding assembly 13 includes a wheel sleeve 131 and a rotating shaft 132 installed on the wheel sleeve 131, the rotating shaft 132 is installed on the wheel sleeve 131 through a second bearing 133, and both ends of the rotating shaft 132 are spherical or spherical-segment-shaped. On this basis, one end of the wheel sleeve 131 is fixed to the net frame 14, and the other end of the wheel sleeve 131 and the rotating shaft 132 are both located in the guide groove of the guide rail 4. The contact area between the wheel sleeve 131 and the rotating shaft 132 and the inside of the guide groove is small, so that the friction resistance between the sliding assembly 13 and the guide rail 4 can be ensured to be small.
In fig. 15 to 21, the screen frame 14 has a rectangular box shape. The first wedge-shaped element 10 may be mounted to the edge of the frame 14. In addition, the number of the sliding assemblies 13 may be four, and the sliding assemblies may be arranged corresponding to the four guide rails 4.
According to an embodiment of the present invention, referring to fig. 18 to 21, a traction frame 15 is respectively disposed at the upstream and downstream of the screen frame 14, the traction frame 15 includes a plurality of mounting arms 151 connected to the screen frame 14, all the mounting arms 151 intersect at a mounting interface 152, and the mounting interface 152 is connected to the chain belt 1. The arrangement of the traction frame 15 can ensure the smooth movement of the chain belt 1.
According to the embodiment of the present invention, referring to fig. 22 to 28, the roller blind assembly 2 further includes a first one-way ratchet 204 and a second one-way ratchet 205 with opposite driving directions, and further, the roller blind assembly 2 further includes a guide shaft 206 and a tension flexible cable 203. The first one-way ratchet 204 and the second one-way ratchet 205 are both arranged on the reel 201; the guide shaft 206 is installed below the reel 201; one end of the tensioning flexible cable 203 is connected with the bottom of the roller shutter body 202, and the other end of the tensioning flexible cable is wound on the second one-way ratchet wheel 205 after being wound on the guide shaft 206. The first one-way ratchet 204 is coupled to the second gear segment 60222 of the gravity energy storage assembly, and the first one-way ratchet 204 is used for driving the tensioning flexible cable 203 to be tensioned and driving the second one-way ratchet 205 to move in a reverse direction towards the first one-way ratchet 204, and the first one-way ratchet 204 drives the reel 201 to rotate through the second one-way ratchet 205. Assuming that the first one-way ratchet 204 rotates clockwise under the action of an external force, the tensioning flexible cable 203 drives the second one-way ratchet 205 to rotate counterclockwise at this time, so as to ensure that the tensioning flexible cable 203 is in a tensioning state, thereby ensuring that the roller shutter body 202 is smoothly unreeled or reeled. On the contrary, if the first one-way ratchet 204 rotates counterclockwise under the external force, the tensioning flexible cable 203 drives the second one-way ratchet 205 to rotate clockwise at this time, so as to ensure that the tensioning flexible cable 203 is in the tensioned state. The tensioning flexible cable 203 may take the form of a tensioning rope, a tensioning wire, or a tensioning chain, among others.
When the fluid kinetic energy conversion device includes a gravitational energy storage assembly, the first one-way ratchet 204 is dynamically coupled to the second gear segment 60222 of the gravitational energy storage assembly, according to an embodiment of the present invention. Further, the second gear segment 60222 can drive the first one-way ratchet 204 to rotate via the one-way transmission assembly 16. The unidirectional transmission assembly 16 may also adopt a unidirectional ratchet structure, see fig. 32 and 33, and includes a connecting shaft 161 and a unidirectional ratchet body 162 mounted on the connecting shaft 161. Of course, the specific structural form of the unidirectional transmission assembly 16 is not limited, as long as the weight member 602 of the gravity energy storage assembly cannot drive the reel 201 to rotate when ascending, and the weight member 602 of the gravity energy storage assembly can drive the reel 201 to rotate when descending. In addition, referring to fig. 34 and 35, in the embodiment of the present invention, a plurality of positions may be provided with the moving speed-changing device 11, and the setting of the transmission ratio is realized by the multi-stage transmission gear in the moving speed-changing device 11. For example, the above motion shifting means 11 may be provided between the second gear segment 60222 and the gravity energy storage assembly.
According to an embodiment of the present invention, referring to fig. 36 to 42, the energy storage assembly may further include a third energy storage assembly 17. Wherein the third energy storing assembly 17 comprises a fifth gear 1706 in mesh with the first gear 3, and a third one-way ratchet 1701 in mesh with the first gear 3 and a fourth one-way ratchet 1702 in mesh with the fifth gear 1706. Wherein, the third one-way ratchet 1701 and the fourth one-way ratchet 1702 are in the same direction and are both arranged on the same power output shaft 1704. Here, "the third one-way ratchet 1701 and the fourth one-way ratchet 1702 are in the same direction" means: the third one-way ratchet 1701 and the fourth one-way ratchet 1702 can drive the power output shaft 1704 to rotate along the pointer, and cannot drive the power output shaft 1704 to rotate counterclockwise; alternatively, the third one-way ratchet 1701 and the fourth one-way ratchet 1702 can both drive the power output shaft 1704 to rotate counterclockwise, but cannot drive the power output shaft 1704 to rotate clockwise. Therefore, no matter what direction the chain belt 1 moves towards the guide rail 4, the first gear 3 can only drive the power output shaft 1704 to move in one direction. Specifically, referring to fig. 40 to 42, it is assumed that the chain belt 1 drives the first gear 3 to rotate clockwise, and at this time, the fifth gear 1706 meshed with the first gear 3 moves counterclockwise, and further the third unidirectional ratchet 1701 rotates counterclockwise, and the fourth unidirectional ratchet 1702 moves clockwise, and at this time, the fourth unidirectional ratchet 1702 drives the power output shaft 1704 to rotate, and the third unidirectional ratchet 1701 does not act; the chain belt 1 drives the first gear 3 to rotate anticlockwise, the fifth gear 1706 meshed with the first gear 3 moves clockwise at the moment, the third one-way ratchet 1701 further rotates clockwise, the fourth one-way ratchet 1702 moves anticlockwise, the third one-way ratchet 1701 drives the power output shaft 1704 to rotate at the moment, and the fourth one-way ratchet 1702 does not act. Thus, the power output shaft 1704 is continuously rotated in one direction at all times to achieve the conversion of the kinetic energy of the fluid.
The two ends of the power output shaft 132 may be designed to have a non-circular power output interface 1705. Further, the power output shaft 132 may be connected to the outside through a power output interface 1705. For example, in fig. 41, a first fitting 1707 and a second fitting 1708 are provided at both ends of the power output shaft 1704, respectively. Wherein the first and second fittings 1707, 1708 may be power take-off gears. Furthermore, it is found from fig. 41 that the third energy storage assembly 17 is mounted by a third bearing 1703.
According to the embodiment of the utility model, in order to fully utilize the kinetic energy of the fluid, the installation depth of the roller shutter assembly 2 in the river channel can be reasonably selected. The fluid flow velocity at the deeper part in the river channel is lower, and the kinetic energy of the corresponding fluid is smaller, so that the roller shutter component 2 is installed corresponding to the upper part of the river channel as far as possible under the condition that the depth of the river channel is enough. And moreover, by reasonably arranging the position of the power conversion assembly in the river runner, the fluid kinetic energy conversion equipment can not be seen from the outside basically.
According to the embodiment of the utility model, a plurality of groups of power conversion components which interact with each other can be arranged along the river channel, so that the kinetic energy of the fluid in the river channel can be fully utilized. In addition, the fluid kinetic energy conversion equipment provided by the embodiment of the utility model has no special requirements on the river channel, and only needs to have certain width and depth and comprise relatively straight flow sections.
One embodiment of the present invention is described in detail below with reference to the accompanying drawings:
referring to fig. 1 to 42, the fluid kinetic energy conversion device includes a plurality of interactive power conversion assemblies distributed along the length direction of the river channel. For the power conversion assembly with interaction, a gear set 5 is arranged between the chains, the gear set 5 comprises a plurality of first gears 3, and the first gears 3 of the gear set 5 are arranged corresponding to the middle parts of the chains. The chain is rectangular ring-shaped, the net frame 14 is rectangular box-shaped, the rolling curtain component 2 is installed at the upstream of the rectangular box-shaped net frame 14, and the rolling shaft 201 of the rolling curtain component 2 can rotate relative to the net frame 14. The upstream and downstream sides of the screen frame 14 are respectively provided with a traction frame 15, and the traction frame 15 comprises four mounting arms 151, wherein the four mounting arms 151 are vertically symmetrical and bilaterally symmetrical, and the four mounting arms 151 intersect at a mounting interface 152. The chain is connected to the mounting interface 152. In addition, the upper and lower edges of the frame 14 are provided with first wedge-shaped members 10, respectively. A stop assembly 8 is mounted at an upstream end position of the guide rail 4, and the stop assembly 8 is switched in position under the action of a second stroke control assembly and a third stroke control assembly.
When the roller blind assembly 2 is moved to the upstream end, the second stroke control assembly controls the stop assembly 8 to move to the locking position, locking the roller blind assembly 2 and the frame 14 to the upstream end. Thereafter, the roller blind assembly 2 starts to be unwound by the first gravity energy storage assembly 6, and when unwinding is completed, the third travel control assembly controls the stop assembly 8 to move to the unlocking position, so that the roller blind assembly 2 and the screen frame 14 move toward the downstream end under the impact of the fluid.
When the roller blind assembly 2 and the frame 14 start to move from the upstream end, the second clutch member is in a coupled state, so that the first gear 3 of the corresponding second gravity energy storage assembly 7 and the third gear 906 of the second gravity energy storage assembly 7 are engaged. Further, the weight member 602 of the second gravitational energy storage assembly 7 stores gravitational potential energy during movement of the roller blind assembly 2 and the frame 14 toward the downstream end. In addition, in the process, the first gear 3 converts the kinetic energy of the fluid through the third energy storage assembly 17. When the roller blind assembly 2 and the net frame 14 move to the downstream end, the weight 602 of the second gravity energy storage assembly 7, the third gear 906 of the first gear segment 60221 thereof is disengaged from the first gear 3 through the second clutch component, and then the weight 602 of the second gravity energy storage assembly 7 descends under the action of gravity and drives the winding shaft 201 to wind.
When the roller blind assembly 2 and the frame 14 start to move from the downstream end, the first clutch member is in a coupled state, so that the first gear 3 of the corresponding first gravity energy storage assembly 6 and the third gear 906 of the first gravity energy storage assembly 6 are engaged. Further, the weight member 602 of the first gravitational energy storage assembly 6 stores gravitational potential energy during movement of the roller blind assembly 2 and the frame 14 toward the upstream end. When the roller blind assembly 2 and the screen frame 14 move to the upstream end, the weight 602 of the first gravity energy storage assembly 6, the third gear 906 of the first gear segment 60221 thereof is disengaged from the first gear 3 through the first clutch component, and then the weight 602 of the first gravity energy storage assembly 6 descends under the action of gravity, and drives the winding shaft 201 to unwind.
So reciprocating, the unwinding of the roller blind assembly 2 at the upstream end and the winding of the roller blind assembly 2 at the downstream end are realized. When the roller shutter component 2 of the first power conversion component A flows downwards, the second power conversion component B is driven to move upwards in a counter-current manner; when the second power conversion component B flows downwards, the first power conversion component A is driven to move upwards in a counter-current mode. Thereby, the roller blind assembly 2 is continuously moved from the upstream end to the downstream end to achieve a continuous conversion of the fluid kinetic energy. In addition, the gravity energy storage assembly continuously realizes the storage and the release of gravitational potential energy.
The fluid kinetic energy conversion equipment provided by the embodiment of the utility model has the advantages that the position or state switching of all the parts is completely realized by self, no power part is additionally arranged, and the whole flow of fluid kinetic energy-reciprocating rotation shape-continuous rotation power shape can be automatically completed. The fluid kinetic energy conversion equipment does not discharge materials, dissipate heat, vibrate or generate noise, and can meet the requirement of environmental protection while utilizing the fluid kinetic energy.
The above embodiments are merely illustrative of the present invention and are not to be construed as limiting the utility model. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the technical solution of the present invention is covered by the claims of the present invention.
