The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The present embodiment provides a self-driven motion conversion apparatus.

In one embodiment, as shown in FIG. 1, it comprises: the drive portion casing 1, the drive portion inner tube 10, the mass 11, the inlet check valve 2, and the outlet check valve 3. The driving part housing 1 has an inner cavity provided with a first air outlet end and a second air outlet end. The driving part inner tube 10 is provided with a tube air inlet and a tube air outlet, and the tube air inlet is communicated with the first air outlet end of the inner cavity. The mass 11 is arranged in the inner cavity, and the mass 11 forms an airtight sliding connection with the inner cavity, specifically, in the present embodiment, the mass 11 forms an airtight sliding fit connection with the driving part housing 1 through an O-ring. Two ends of the mass block 11 and the first air outlet end and the second air outlet end respectively form an upper air-tight cavity and a lower air-tight cavity in a one-to-one correspondence manner; a driving elastic member for restoring the mass 11 is provided in the airtight chamber. The plurality of inlet one-way valves 2 are at least arranged at the first air outlet end and the second air outlet end of the inner cavity; the air inlet end of the inlet one-way valve 2 is communicated with the outside, and the air outlet end of the inlet one-way valve 2 is communicated with the inner cavity. Go out to check valve 3 the inlet end that goes out to check valve 3 with the second end of giving vent to anger with the pipe gas outlet intercommunication, the end of giving vent to anger that goes out to check valve 3 communicates with the output device that is used for power take off.

The device is used to secure the drive section housing 1 to an object which is subject to vibration or fluctuating movement and to cause the drive section inner tube 10 to axially follow substantially the direction of the reciprocating movement, for example in the case of a ship, to the bow of a relatively high pitch and to locate the drive section housing 1 vertically. Then, as the ship bumps, the mass 11 will have a hysteresis relative motion with respect to the driving part housing 1 due to its own inertia, and then the corresponding side airtight chamber is pressed to allow gas to flow from the outlet to the one-way valve 3 into the output device, so as to drive a functional device such as a generator. Meanwhile, the airtight cavity on the other side expands, air is sucked from the inlet one-way valve 2, and then under the reset action of the elastic element of the driving part and the return action of the reciprocating motion, the mass block 11 extrudes the airtight cavity on the other side again to continuously generate air flow to push the output device. It should be noted that although gas is used as the pressure medium in the discussion, it is obvious that liquid can also be used as the pressure medium, but it is preferable to use gas, and firstly, gas has small inertia and is beneficial to the pushing of the mass block 11; and secondly, the gas has compressibility, so that the difference between the peak and the valley of the output airflow is weakened to a certain extent, and the stable output of the output device is facilitated.

Compared with the mode of converting energy by utilizing the relative motion generated by a buoyancy device in a fixed frame, the mode of generating the relative motion in the fixed frame to generate the energy has the advantages that the fixed frame is not needed, namely, the driving part shell 1 is not needed to be stably connected with the ground, so that the device can be installed in a ship running on the sea surface and generates energy along with the movement of the ship (obviously, the device can also be installed on an automobile with bumpy road conditions), and is not required to be installed in a fixed place like the prior art. The mass block 11 of the device can output airflow outwards in two reciprocating directions, so that the working efficiency is improved. And it carries out the transmission through the air current, has avoided the high and transmission efficiency low mechanical structure of complexity, has improved device operational reliability and energy output ability. And because the energy storage effect of the elastic part of the driving part, the external irregular vibration or bumping motion is weakened and converted into regular reciprocating motion, thereby being beneficial to the stability of energy output.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 1, the drive section inner tube 10 is disposed in the inner cavity of the drive section housing 1; the mass block 11 is annularly sleeved on the driving part inner tube 10, and the mass block 11 is in airtight sliding connection with the outer wall of the driving part inner tube 10; the second air outlet end and the pipe air outlet are positioned on the same side of the driving part shell 1.

In the present embodiment, the structure of the inner tube 10 of the driving portion is disposed in the driving portion casing 1, so that after the mass block 11 extrudes the upper cavity, the gas firstly enters the one-way valve 3 through the inner tube 10 of the driving portion, and then the second gas outlet end and the gas outlet of the tube are arranged on the same side of the driving portion casing 1, so that the one-way valve 3 is arranged in a centralized manner, the overall structure of the device is compact, and the occupied volume is reduced.

Based on the above embodiments, in a preferred embodiment, the output device is a turbine 8, and the turbine 8 is designed in a turbine blade structure, so that the discontinuous airflow formed by the up-and-down movement of the mass 11 is output as a relatively continuous rotation, the output has stability and continuity, and the working efficiency of the device is improved.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 3, the outlet check valve 3 includes: valve seat 18, inner spool 21, and outer spool 26. The valve seat 18 is connected between the drive housing 1 and the turbine 8 and has a valve seat inlet 27, a valve seat outlet 24 and a valve chamber 13. The valve chamber 13 communicates between the valve seat inlet 27 and the valve seat outlet 24. The valve seat inlet 27 includes an outer flow passage 20 and an inner flow passage 19, the inner flow passage 19 communicates with the lower end of the inner tube 10 of the driving part, and the outer flow passage 20 communicates with the lower chamber. The inner spool 21 and the outer spool 26 are both disposed within the valve chamber 13. The inner valve body 21 makes the fluid flow in one direction from the inner flow passage 19 to the valve seat outlet 24. The outer spool 26 provides one-way fluid flow from the outer flow passage 20 to the seat outlet 24. It should be noted that the check valve core here may be in the form of a spring stopper (e.g. a combination of an inner core spring 23 and a stopper inner valve core 21, or a combination of an outer core spring 25 and a stopper outer valve core 26) as in the present embodiment, or may be in the form of a valve structure.

The outlet one-way valve 3 with the double valve cores is structurally integrated with two one-way valves which can be originally connected with the inner pipe 10 of the driving part and the lower cavity respectively, so that the structure is more compact and reasonable, the outlet one-way valve is convenient to connect with a subsequent turbine 8, and the assembly time is reduced.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 3, the outlet check valve 3 further includes a check valve inner tube 22 fixed inside the valve chamber 13 and communicating with the inner flow passage 19. The inner valve core 21 is arranged in the inner pipe 22 of the one-way valve; and the outer valve core 26 is sleeved outside the one-way valve inner tube 22.

The structure that the annular outer valve core 26 wraps the inner valve core 21 makes full use of the cross-sectional area of the valve seat 18, so that the valve core is easier to push. Because the valve core is pushed and influenced by two factors, namely the air pressure and the air pressure acting area. In the present embodiment, the outer valve core 26 and the inner valve core 21 occupy the cross-sectional area of the valve seat 18 together, and the largest possible air pressure acting area is obtained in the valve seat 18 with the same diameter, so that the valve cores are more easily pushed away to realize air flow output without requiring excessive pushing air pressure. And it realizes corresponding function only through setting up the simple structure of check valve inner tube 22, has characteristics simple, the low cost of manufacture.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 1 and 2, the turbine 8 includes a volute 7 and a turbine 6. The volute 7 is provided with a turbine chamber 16. The turbine 6 is arranged in a turbine cavity 16, and as in the prior art, an output shaft 14 is arranged on the large end surface of the turbine 6, and an air outlet 17 is arranged on the volute 7 close to the small end of the turbine 6. The outer side of the turbine cavity 16 is provided with a volute air passage 5 communicated with the turbine cavity. The volute air passage 5 is arranged around the turbine 6 and is spirally involute as shown in fig. 1, that is, the opening degree of the volute air passage 5 from the inner end to the outer end is gradually enlarged along the spiral line when viewed in the direction of fig. 1. The outlet one-way valve 3 is communicated with the outer end of the volute air passage 5.

Because the turbine 8 is in operation, the air flow is continuously flowing out of the fan blades of the turbine 6, and the air flow is continuously reduced from the outermost end of the volute air passage 5 connected with the outlet one-way valve 3 to the innermost end, the spiral involute volute air passage 5 follows the trend of the air flow reduction. The air passages with equal opening degrees at all positions face the problems that the air volume close to the connection position of the outlet one-way valve 3 is large, and then the air volume is weakened, so that the stress of the turbine 6 is unbalanced, the service life of a shaft member and a corresponding bearing is not favorable, and the friction force of a rotating shaft is increased due to uneven stress, so that the turbine 6 is difficult to push, and the power conversion output is influenced. The spiral involute volute air passage 5 is reduced in size, so that the air flow flowing through the spiral involute volute air passage is kept strong all the time from front to back, the turbine 6 is stressed and rotated uniformly after being arranged around the turbine 6 by 360 degrees basically, the turbine 6 is convenient to push to output power, and the energy conversion efficiency is improved.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 2, the width of the scroll gas passage 5 in the axial direction of the turbine 6 is gradually reduced from the outer end to the inner end as viewed from the view direction. The aforementioned opening degree of the volute air passage 5 can be understood as the height of the volute air passage 5 in fig. 2, and the height of the volute air passage 5 is not only gradually reduced, but the width of the volute air passage 5 is also gradually reduced in the present embodiment, so as to better meet the decreasing trend of the air flow from the outer end to the inner end of the volute air passage 5.

Based on the above embodiment, in a preferred embodiment, as shown in fig. 2, the volute air passage 5 communicates with the turbine chamber 16 through the through groove 15, and the width of the through groove 15 is not greater than the width of the inner end of the volute air passage 5 in the axial direction of the turbine 6. The width of the through groove 15 does not exceed the minimum width of the endmost volute air passage 5, that is, the difference between the width of the volute air passage 5 closer to the front end of the air flow and the width of the through groove 15 is larger, as shown in the through groove 15 connected with the volute air passage 5 in fig. 2, such a structure enables the blown air flow to be more focused on the blade area where the turbine 6 can exert the most effect after being blown out from the through groove 15, and enables the air flow in the volute air passage 5 to maintain pressure through the narrow through groove 15, so that the uniformity of the air flow is kept before and after the air flow, the turbine 6 is favorably pushed in a balanced manner, and the conversion efficiency is improved.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 1, the outlet check valve 3 is connected to the turbine 8 through a hose 4. Because the position (such as the bow) with the largest vibration or fluctuation and the place (such as a cabin) needing power output are not positioned at one position, the arrangement of the device can be convenient through rubber pipe connection, the advantage of pneumatic transmission is embodied again, the power can be transmitted to a far position without arranging complicated mechanical transmission parts, and the installation and the arrangement of the device are extremely simple and convenient.

In a preferred embodiment, as shown in fig. 1, the hose 4 is provided in an S-shape, based on the above-described embodiments. Sometimes the device can also be used on some equipment with larger vibration, and the vibration equipment is not too far away from the place where power is needed, and the output is generally carried out on the adjacent ground. Because the hose 4 cannot be stretched and compressed in the axial direction, if a shorter hose 4 is used for connection, the movement range of the driving part housing 1 is sometimes limited, but the S-shaped hose 4 is not limited, so that the applicability of the device is improved.

Based on the above embodiments, in a preferred embodiment, as shown in fig. 1, the driving part elastic member is provided in both of the airtight chambers, and the driving part elastic member is a spring abutting against the mass 11 and the driving part housing 1. Specifically, the present embodiment is implemented by the upper chamber spring 12 provided in the upper chamber and the lower chamber spring 9 provided in the lower chamber both abutting against the mass 11 and the drive unit housing 1. Compared with the spring with stretching and compressing functions, the structure of the upper spring and the lower spring enables the springs to play the role of a pressure spring, and the mass block 11 and the driving part shell 1 do not need to be specially fixed for avoiding separation like a tension spring, so that the assembly operation difficulty is reduced, the steps are simplified, and the production and the manufacture are convenient.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the spirit or scope of the invention.
