Description

Technical Field

[0001] The present invention relates to a one-way leaf spring pressure-controlled solar hot air space, which performs hot air pressurization and pressure control in a fully natural passive manner. Hot air can be input into the hot air space, and the quality and pressure of the hot air can be increased, and the pressure value can be controlled within a certain range. It can be applied to civil, agricultural and industrial occasions that require hot air, utilize solar energy, and comprehensively utilize renewable energy. It belongs to the field of solar energy technology and related environmental protection and energy-saving technology. Background Art

[0002] In the industrial and civil fields, renewable energy technology systems such as solar energy often appear in the form of active and passive hybrids, as well as comprehensive utilization systems of multiple energy technologies. The ultimate design concept is a fully natural passive system, which has the best energy, environmental and resource effects.

[0003] Solar thermal air technology systems are used in many industrial and civil applications. These applications often require hot air at a certain pressure and have certain continuity requirements for the hot air flow. Solar thermal air systems often need to be pressurized to a certain pressure range before they can be used in actual working conditions.

[0004] The rational operation of solar energy technology systems requires parameter control in many cases. In fact, industrial and civil technology systems are mostly composite systems of equipment systems and automatic control systems. The pressure control system of solar hot air is a "secondary technology system" of the solar energy technology composite overall system. In order to achieve the most reasonable and optimized way of energy, environment and resources, its control system should also be designed with all-natural, passive and zero-energy technical requirements as the limit of the concept.

[0005] The all-natural passive system has the best energy, environmental and resource effects. The design concept of the entire engineering technology system and all its subsystems should be all-natural, passive and zero energy consumption. Only in this way can the best energy, environmental and resource effects be achieved. But in reality, its development and application are not enough.

[0006] Generally speaking, the control of solar energy technology systems mostly adopts active power-consuming electrical or digital control systems. The development and application of zero-energy, all-natural and passive control systems designed with the concept of full system and all-natural is still insufficient. That is, the design and development of passive control of the control system of solar energy technology system is insufficient. Not only is it neglected in concept, but the development of its technical measures also has certain difficulties and shortcomings. It is necessary to develop and apply reasonable and optimized technical measures.

[0007] Therefore, the related passive zero-energy solar hot air boost pressure control system has a large application space. How to generate hot air within a set pressure range in a fully natural passive way is a technical problem with a certain degree of difficulty. Similarly, on the other hand, the related technical system has considerable development and application space. Summary of the invention

[0008] In view of the above difficulties and shortcomings, the present invention provides a one-way leaf spring pressure-controlled solar hot air space, which can input hot air into the hot air space, and can achieve quality and pressure increase of the hot air, and at the same time can control its pressure value within a certain range.

[0009] The technical solution of the present invention is:

[0010] A one-way leaf spring pressure-controlled solar thermal air space, the system composition of which is:

[0011] It is composed of solar hot air inlet pipe 2, one-way pressure control sealing plate 3, solar hot air pressurization space 1, hot air opening and closing outlet 9, one-way pressure control spring wall frame 4, one-way plate rotation wall groove 5, one-way plate rotation pivot wall frame 6, one-way pressure control spring 7, one-way plate rotation pivot 8.

[0012] A one-way leaf spring controls the pressure of a solar thermal air space, and its system structure is:

[0013] The outside air heating intake structure is:

[0014] The solar hot air inlet duct 2 is connected to the solar hot air pressurized space 1 .

[0015] The hot air taking channel structure is:

[0016] The solar hot air pressurization space 1 is provided with a hot air opening and closing outlet 9 connected thereto.

[0017] The one-way pressure-controlled sealing plate 3 is arranged in the following structure:

[0018] The upper end of the one-way pressure control sealing plate 3 is opened and a one-way plate rotation pivot 8 is built in. The one-way plate rotation pivot 8 is connected to the one-way plate rotation pivot wall frame 6. The upper end of the one-way pressure control sealing plate 3 is built in the one-way plate rotation wall groove. The one-way pressure control sealing plate 3 is also connected to the one-way pressure control spring 7, and its connection point is a retractable and movable connection end. At the same time, the other end of the one-way pressure control spring 7 is the one-way pressure control spring wall frame 4, and its connection point is an immovable fixed end.

[0019] The length and width of the one-way pressure-controlled sealing plate 3 are both greater than the maximum length and width of the corresponding hot air inlet passage. It can be ensured that when the plate surface naturally falls to a plumb state, the plate surface can cover and seal the hot air inlet of the solar hot air inlet duct 2 formed by the opening of the south wall. The one-way pressure-controlled sealing plate 3 will not rotate outwardly toward the south wall to form a hot air inlet, but can only rotate inwardly toward the south wall to form a hot air inlet.

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is based on the above-mentioned internal and external components, structures and structural relationships of the one-way leaf spring pressure-controlled solar hot air space. On the above basis, the present invention can achieve the quality and pressure increase of hot air, and at the same time can passively control its pressure value within a certain range. Its technical system implements and applies a passive zero-energy mechanical pressure automatic control system.

[0025] The technical principle of the present invention is:

[0026] The opening principle of the channel for hot air to enter the hot air space is:

[0027] When the hot air in the solar hot air inlet pipe 2 reaches a sufficient pressure, the outer plate surface of the one-way pressure control sealing plate 3 can be pushed open to form a hot air inlet channel, so that the hot air enters the solar hot air boosting space 1.

[0028] The principle of the one-way pressure-controlled sealing plate 3 opening inwards is:

[0029] The hot air inlet channel of the solar hot air boosting space 1 is composed of the outlet of the solar hot air inlet pipe 2, the inner plate surface of the one-way pressure-controlled sealing plate 3 which is rotated inward to a certain angle around the one-way plate rotation pivot 8 in a non-plumb position, and the inner surface of the south wall of the solar hot air boosting space 1.

[0030] When the thrust of the hot air on the outer surface of the one-way pressure control sealing plate 3 is sufficient to push the pressure control plate to rotate around the one-way plate rotation pivot 8 into the solar hot air boosting space 1, the hot air inlet is formed, and the hot air enters the solar hot air boosting space 1 in this way.

[0031] The flowing hot air in the solar hot air inlet duct 2 forms an inward pressure on the outer plate surface of the one-way pressure-controlled sealing plate 3, which generates an inward thrust of the one-way pressure-controlled sealing plate 3, causing the one-way pressure-controlled sealing plate 3 to open inward.

[0032] The principle of increasing the pressure of the solar hot air boosting space 1 is:

[0033] The hot air flows into the solar hot air pressurization space 1, causing the air quality and temperature in the space to increase. Under the condition that the space is closed and thermally insulated, the pressure in the space gradually increases.

[0034] The principle of closing the hot air passage of the one-way pressure-controlled sealing plate 3 is:

[0035] The pressure in the solar hot air boosting space 1 gradually increases, and the inner plate surface pressure of the one-way pressure-controlled sealing plate 3 gradually increases. A pressure difference is generated inside and outside the one-way pressure-controlled sealing plate 3. The pressure of the one-way pressure-controlled sealing plate 3, that is, the pressure of the solar hot air boosting space 1, is gradually increasing. When the inner plate surface pressure of the one-way pressure-controlled sealing plate 3 is greater than the outer plate surface pressure, the one-way pressure-controlled sealing plate 3 falls to the plumb bob position, which can close the passage of the flowing hot air in the solar hot air inlet pipe 2 to the solar hot air boosting space 1. At this time, the inner plate surface pressure of the one-way pressure-controlled sealing plate 3 is the pressure of the combined effects of the weight of the one-way pressure-controlled sealing plate 3, the increase in air mass and the temperature rise in the hot space, etc. The above-mentioned effects generate an outward thrust of the one-way pressure-controlled sealing plate 3.

[0036] When the inner surface pressure of the one-way pressure-controlled sealing plate 3 is greater than the outer surface pressure, the outward thrust of the one-way pressure-controlled sealing plate 3 is greater than the inward thrust, and the one-way pressure-controlled sealing plate 3 rotates outward around the one-way plate rotation pivot 8 and falls to the plumb bob position, thereby closing the channel of the flowing hot air in the solar hot air inlet pipe 2 to the solar hot air boosting space 1.

[0037] The pressure control action principle of the one-way pressure control spring 7 is:

[0038] The present invention has two opposite effects on the channel closing of the one-way plate. The thermal pressure thrust of the hot air space, together with the deadweight of the plate, can close the channel of the solar hot air temperature and mass pressurizing collector 3 to the solar hot air pressurizing space 1, which can be called the plate closing thrust. The inflow pressure of the outside hot air, and the spring preload, together can open the channel of the solar hot air temperature and mass pressurizing collector 3 to the solar hot air pressurizing space 1, which can be called the plate opening thrust.

[0039] The weight of the plate, the spring preload and the hot air pressure in the hot space determine the outward thrust of the plate. The spring preload and the weight of the plate can be set. Thus, the setting of the spring preload can determine the pressure range after closing.

[0040] When the pressure of the solar hot air boosting space 1 is lower than the set range, the one-way pressure control spring 7 reduces the channel opening resistance of the one-way pressure control sealing plate 3. By controlling the lower limit pressure range of the hot space in this way, the lower limit pressure of the hot space can be reduced. That is, when the intake pressure is less than the pressure formed by the deadweight of the one-way pressure control sealing plate 3, the quality and temperature can be increased in the solar hot air boosting space 1, thereby determining the lower limit pressure range of the hot space. Obviously, increasing the spring preload of the one-way pressure control spring 7 can reduce the lower limit pressure range of the hot space. On the contrary, increase.

[0041] The one-way pressure control spring 7 controls the upper limit of the pressure of the thermal space through its spring preload. The one-way pressure control spring 7 reduces the channel closing thrust of the one-way pressure control sealing plate 3, thereby controlling the upper limit range of the pressure of the thermal space. Obviously, under different conditions of variable or constant intake pressure, the spring preload setting of the one-way pressure control spring 7 can play a role in controlling the pressure within a certain range. For example, under strong intake conditions, reducing the spring preload setting of the one-way pressure control spring 7 can increase the channel closing thrust of the one-way pressure control sealing plate 3. At this time, the hot air pressure in the thermal space can be reduced, that is, the upper limit range of the pressure of the thermal space can be controlled.

[0042] If no spring is provided, the pressure of the thermal space in the initial working condition will drop to the space pressure value balanced only by the deadweight of the plate. Here, the spring preload determines the minimum pressure range of the thermal space. The initial space pressure of the plate with a preloaded spring is higher than the initial space pressure of the plate alone.

[0043] The one-way pressure control spring 7 controls the upper limit of the pressure of the thermal space through its preload. Because the pressure of the hot air is higher than a certain value, it works together with the pressure formed by the fixed preload to shut off the channel. Since the shut-off pressure is the sum of the pressure formed by the preload and the pressure of the thermal space, and since the spring preload is fixed, the maximum pressure range of the thermal space can be controlled by changing the setting of the spring preload.

[0044] The principle of maintaining the set pressure of the solar hot air boosting space 1 is:

[0045] When the inner plate pressure of the one-way pressure control sealing plate 3 is greater than the maximum pressure of the outer plate, the hot air inlet channel is closed, resulting in the closure of the hot air space of the solar hot air boosting space 1. The solar hot air boosting space 1 is provided with thermal insulation to maintain the hot air pressure value within a set range.

[0046] The one-way closing setting mechanism of the one-way pressure-controlled sealing plate 3 is:

[0047] The hot air inlet channel is a channel consisting of the outlet of the solar hot air inlet duct 2 and the opened one-way pressure control sealing plate 3, and has a maximum length and width. This channel is the hot air inlet formed by the south wall opening.

[0048] The length and width of the one-way pressure-controlled sealing plate 3 are both set to be greater than the maximum length and width of the corresponding hot air inlet channel. It can be ensured that when the plate surface naturally falls to the plumb state, the plate surface can cover and seal the hot air inlet formed by the opening of the south wall. In this way, the one-way pressure-controlled sealing plate 3 will not rotate outwardly toward the south wall surface to form a hot air inlet, but can only rotate inwardly toward the south wall to form a hot air inlet, forming an opening and closing with working conditions.

[0049] The one-way pressure-controlled sealing plate 3 deviates from its plumb bob position and rotates inwardly and upwardly around the one-way plate rotation pivot 8 to open the hot air inlet passage, and rotates inwardly to the plumb bob direction to close the passage.

[0050] Under certain working conditions, the outer plate surface and the inner plate surface of the one-way pressure control sealing plate 3 can reach a pressure balance and maintain the inlet passage. The pressure on the inner plate surface will be greater than the pressure on the outer plate surface at a certain moment, and the one-way pressure control sealing plate 3 can rotate outward around the one-way plate rotation pivot 8 and fall to the plumb bob direction to close the hot air inlet passage.

[0051] The principle of automatic inflation and pressurization cycle after hot air is taken is:

[0052] Due to the closed space and thermal insulation, the solar hot air boosting space 1 can maintain the boosting pressure after the channel is closed. At this time, the hot air opening and closing outlet 9 is in a closed state. When taking the boosted hot air, the hot air opening and closing outlet 9 is opened, and the boosted hot air in the solar hot air boosting space 1 is depressurized and flows out.

[0053] At this time, the pressure on the inner and outer surfaces of the one-way pressure control sealing plate 3 gradually becomes unbalanced. The inner surface pressure of the one-way pressure control sealing plate 3 gradually decreases, resulting in a gradual decrease in the outward thrust of the one-way pressure control sealing plate 3 and a gradual increase in the inward thrust of the one-way pressure control sealing plate 3.

[0064] When the inward thrust on the one-way pressure-controlled sealing plate 3 is sufficient to push the pressure-controlled plate to rotate inward around its rotation axis, the hot air inlet opens, and the hot air at outdoor atmospheric pressure enters the solar hot air boosting space 1 through the hot air channel.

[0055] Due to the closed space and thermal insulation, the mass and temperature of the air entering the solar hot air boosting space 1 increase, causing the pressure in the space to gradually increase again. In this way, a reverse pressure difference is generated inside and outside the one-way pressure control sealing plate 3. When the pressure on the inner plate surface of the one-way pressure control sealing plate 3 is greater than the pressure on the outer plate surface, it falls to the plumb bob position due to gravity, and the hot air channel can be closed again, starting the second pressure maintenance cycle.

[0056] The working process of the technical system of the present invention is:

[0057] The system process of the present invention includes sequential cyclic processes such as air intake pressurization, closed pressure maintenance, pressure relief and use, and cyclic air intake pressurization.

[0058] The intake boost process is:

[0059] Due to the spring setting, the channel is initially open.

[0060] Hot air equipment such as solar air collectors will continue to increase the quality and temperature of the enclosed space. Under the above working conditions, hot air enters the solar hot air boosting space 1 and increases the quality and temperature of the solar hot air boosting space 1.

[0061] The pressure in the solar hot air boosting space 1 gradually increases, and the inner plate surface pressure of the one-way pressure control sealing plate 3 gradually increases. A pressure difference is generated inside and outside the one-way pressure control sealing plate 3. When the inner plate surface pressure of the one-way pressure control sealing plate 3 is greater than the outer plate surface pressure, the thrust generated by the pressure difference and the force of the composite plate's deadweight cause the one-way pressure control sealing plate 3 to fall to the plumb bob position, closing the hot air passage of the solar hot air inlet duct 2 to the solar hot air boosting space 1. At this point, the boosting process ends, and the pressure maintenance and use stages begin.

[0062] The closed pressure maintenance process is:

[0063] After the hot air passage is closed by the one-way pressure-controlled sealing plate 3, the solar hot air boosting space 1 can maintain the boosted pressure due to the closed space and thermal insulation.

[0064] The pressure relief and use process is:

[0065] When the pressurized hot air is taken, the hot air opening and closing outlet 9 is opened, the pressurized hot air in the solar hot air pressurization space 1 is depressurized, and the pressurized hot air flows out.

[0066] The cycle of air intake and pressurization process is:

[0067] As the pressure of the solar hot air boosting space 1 decreases after use, the pressure on the inner surface of the one-way pressure control sealing plate 3 gradually decreases. When it decreases to a level lower than the pressure on the outer surface of the one-way pressure control sealing plate 3,

[0068] When the thrust of the hot air from the hot air equipment such as the solar air collector on the one-way pressure control sealing plate 3 is sufficient to push the pressure control plate to rotate around the one-way plate rotation pivot 8 into the solar hot air boosting space 1, a hot air inlet is formed. In this way, the hot air enters the solar hot air boosting space 1 through the channel formed by the one-way plate and the heat collecting air inlet. The storage and use of the boosted hot air in the solar hot air boosting space 1 begins to cycle, and the air intake boosting process is cycled again.

[0069] The process of the pressure control action of the one-way pressure control spring 7 is:

[0070] When the pressure of the solar hot air boosting space 1 is lower than the set range, the one-way pressure control spring 7 reduces the channel opening resistance of the one-way pressure control sealing plate 3. By controlling the lower limit pressure range of the hot space in this way, the lower limit pressure of the hot space can be reduced. That is, when the intake pressure is less than the pressure formed by the deadweight of the one-way pressure control sealing plate 3, the quality and temperature can be increased in the solar hot air boosting space 1, thereby determining the lower limit pressure range of the hot space. Obviously, increasing the spring preload of the one-way pressure control spring 7 can reduce the lower limit pressure range of the hot space. On the contrary, increase.

[0071] The one-way pressure control spring 7 reduces the channel closing thrust of the one-way pressure control sealing plate 3, thereby controlling the upper limit range of the thermal space pressure. Obviously, in different cases where the intake pressure is variable or constant, the spring preload setting of the one-way pressure control spring 7 can play a role in controlling the pressure within a certain range. For example, under the condition of strong intake, reducing the spring preload setting of the one-way pressure control spring 7 can increase the channel closing thrust of the one-way pressure control sealing plate 3. At this time, the hot air pressure in the thermal space can be reduced, that is, the upper limit range of the thermal space pressure can be controlled.

[0072] The technical system functions of the present invention are:

[0073] It can increase the quality and pressure of hot air, and passively control its pressure value within a certain range.

[0074] The technical and application characteristics of the present invention are:

[0075] The invention performs hot air boosting and pressure control in a completely natural way. The system design is simple, the structure is simple, the manufacturing is simple, and the cost is low. It operates in a completely natural, passive way and is low cost. Passive zero-energy mechanical pressure control replaces electrical or digital automatic control systems that consume power, have high investment and high maintenance costs.

[0076] The application scenarios of the technical system of the present invention are:

[0077] The present invention can improve the quality and pressure of solar hot air, and provide high-temperature and high-pressure solar hot air with pressure controlled within a certain range. It can be applied to some civil, industrial and agricultural production occasions that require high-pressure hot air. For example, heating, drying, using hot air power to propel and generate electricity, etc.

[0078] The application prospects of the technical system of the present invention are:

[0079] Passive energy and industrial systems have good energy, environmental protection, and material effects. This system belongs to the above-mentioned field technology and has good development and application prospects.

[0080] The technical system of composite equipment system and control system adopts passive control system, which is the secondary system of the overall composite technical system. Its control system adopts passive control secondary system, which can achieve zero energy consumption and optimal energy, environment and resource effects of the whole system, and has a large development space and application prospects.
