Description

The present invention relates to a stabilization processing method that put to waste disposal sites.

  Since the management-type waste final disposal site continues to decompose even after landfill is completed, the leachate treatment facility, etc. must continue to operate until the disposal site is abolished. The period from closure to abolition is said to require several decades, and in order to shorten the period until abolition, measures to stabilize waste are required.

  Therefore, the leachate collection pipe installed above the impermeable sheet is connected to the air supply facility at the waste final disposal site where the impermeable sheet is laid on the bottom ground, and a degassing pipe is set up from the leachate collection pipe. The air generated from the air supply equipment is aerated through the sewage collecting pipe to supply air that satisfies the aerobic condition to the landfill waste. A method for early stabilization of landfill waste at the final disposal site for diffusion (for example, Patent Document 1) and a protective soil layer made of a water permeable material at the bottom of the waste disposal site, and in the protective soil layer A perforated pipe is buried, and one end of the perforated pipe is connected to a vacuum pump via a steam-water separation means, and the leachate and gas staying inside the disposal site are sucked by driving the vacuum pump. Exhaust the separated gas and leachate respectively. , Waste disposal method characterized by guiding the leachate treatment facility (for example, Patent Document 2) are proposed.

  In the former prior art, air that satisfies the aerobic condition is supplied to the landfill waste by aeration through the sewage collecting pipe from the air supply facility, and the gas generated by the decomposition uses the gas vent pipe. The aerobic decomposition can be promoted by diffusing into the atmosphere, and in the latter prior art, waste can be stabilized quickly and uniformly by forced ventilation inside the disposal site. it can.

  In both of the above prior arts, stabilization processing time can be shortened by air supply or forced ventilation, but it takes a long time before the waste is stabilized and the final disposal site is abolished. Become. In addition, in order to perform air supply or forced ventilation during the period, there is a problem that it costs power costs for driving the apparatus together with maintenance costs.

The present invention has been made in consideration of the above problems, it is possible to shorten the time required for stabilization to provide a stabilization processing method that put in landfills that self-sufficient efficiently power required Objective.

The invention according to claim 1 is provided with a vent pipe having a plurality of vent holes in the waste accumulation layer, and connected to the vent pipe with an air feeding means using a solar cell as a driving source.

According to the configuration of the first aspect, the air supply means is driven by the electric power generated by the solar cell, and the air sent from the air supply means to the vent pipe is sent to the waste accumulation layer to promote aerobic decomposition. Early stabilization becomes possible. And a waste disposal site has a vast unused plane, and can install many solar cell panels easily. Further, when the solar radiation becomes small and the illuminance decreases, the output current of the solar cell 12 decreases, and the electric power necessary to drive the DC motor cannot be obtained. When the value becomes equal to or less than a predetermined value, the load of the direct current motor is reduced by changing the number of compressed air producing sections that generate compressed air to be reduced, and stable driving can be continued. In addition, if the output of a solar cell increases and exceeds the said predetermined value, the number of the compressed air production parts which produce compressed air can be increased, and solar radiation can be efficiently used for manufacture of compressed air. Furthermore, since the inner surface of the excavation hole is consolidated, even if a vent pipe smaller than the excavation hole is inserted, the excavation hole does not collapse. It can be formed, and the air permeability of the vent pipe can be ensured by this crushed stone filling portion.

According to the second aspect of the present invention, when the excavation rod rotates, the excavated waste is pressed against the inner surface of the excavation hole by the trowel surface, and the inner surface of the excavation hole is consolidated. There is no need to discharge.

When the voltage is equal to or lower than the voltage, the calculation means 22 performs control (tracking control) so that the output voltage of the solar cell 12 is maximized.

  The constant input voltage control means 14 includes an error voltage detection means 23 for detecting an error voltage between the reference voltage and the output voltage of the electric control means 21, and the output voltage of the solar battery 12 is the rated output of the DC motor 15. When the reference voltage based on the error voltage is exceeded, the DC motor 15 is controlled to drive at the rated output according to the magnitude of the error voltage output from the error voltage detection means 23 (constant voltage control), and the rated output is exceeded. The surplus power is supplied (sold) to the commercial power source, used as a drive source for other on-site facilities, or used for power storage. In this case, the use of surplus power can be controlled by the control means 17, for example, when the solar cell 12 generates power exceeding the power required for the compressed air production apparatus 11 to pump predetermined air Then, the control means 17 detects this, and the control means 17 controls to use the surplus power exceeding any necessary power for any of the above.

  The control means 17 also controls the DC motor 15 to stop when an abnormality occurs in the DC motor 15 or the like.

  The air compressor 16 is a multi-cylinder, two-cylinder, horizontally opposed type, and has a rotary shaft input piston type in which the air discharge amount changes depending on the rotation speed using a DC motor 15 as a drive source, as shown in FIG. A plurality of (two) compressed air production units 33 each having a cylinder 31 and a piston 32 are provided, and the compressed air production unit 33 reciprocates within the cylinder 31 of the piston 32 through the intake valve.

  Further, the control means 17 is provided with an unload valve control means 24, and this unload valve control means 14 is provided when the solar radiation becomes small and the output voltage of the solar cell 12 becomes lower than the preset output of the DC motor 15. The unload valve drive unit 25 opens the unload valve 37 of one of the compressed air production units 33, and the one compressed air production unit 33 is brought into an unloaded state. When the output voltage of the battery 12 exceeds the set output of the DC motor 15, the unload valve drive unit 25 closes the unload valve 37, and the compressed air is produced again in the two compressed air production units 33. The air compressor 16 is controlled. The preset power setting may be substantially the same as or less than the rated power.

When the illuminance exceeds a predetermined value from this state, the unload valve 37 is closed and again two compressed air The production unit 33 may be controlled to produce compressed air.

The rotational motion obtained by the DC motor 15 is converted into the reciprocating motion of the piston 22 by the crank device 101. The crank device 101 includes a crankshaft 102, a connecting rod (connecting rod) 103, and a planetary mechanism 104 interposed between the crankshaft 102 and the connecting rod 103. The connecting rod 103 is the compressed air production unit. The structure is connected to 33. 8 to 12, only a schematic configuration in the mechanical drive system is shown, and other peripheral configurations such as a valve operating mechanism of an intake / exhaust system are not shown.

The crankshaft 102 is a portion connected to the rotation side, and is composed of a main shaft 110, a crank arm 111, and a crankpin 112, and the main shaft 110 is rotatably supported by a crankcase 114 via a bearing 113. In addition, the axis of the main shaft 110 and the crank pin 112 are parallel. Then, the main shaft 110 is rotated by the DC motor 15 . The two compressed air production sections 33 and 33 are provided with crank devices 101 and 101, respectively, and these two crank devices 101 and 101 are driven by the rotation of the common main shaft 110.

  The connecting rod 103 is a portion connected to the piston 32 of the compressed air production unit 33 on the reciprocating side, and specifically, is integrally formed with the piston 115. As shown in the figure, the connecting rod 103 is formed into a thin rod shape having substantially the same thickness over the entire length, and the piston 32 is also formed into a thin disk shape, and there is no skirt portion as in the conventional general well-known structure, and these reciprocating motions. The weight of the part is reduced.

  The connecting rod 103 and the piston 32 have an integral structure, as will be described later, which is a structure that can be adopted because the connecting rod 103 reciprocates linearly. The connecting rod 103 and the piston 32 may be pivotally connected to each other via a piston pin (not shown) for the purpose of absorbing machining errors and assembly errors of parts.

  The planetary mechanism 104 is a portion that connects the crankshaft 102 and the connecting rod 103, and includes an annular fixed internal gear 120 as a sun member and a planetary gear 121 as a planetary member that meshes with the fixed internal gear 120. Has been.

  The fixed internal gear 120 is fixedly provided on the crankcase 114, and a sun gear 120a on the inner periphery of the cylinder is disposed concentrically with the main shaft 110 of the crankshaft 102.

  The planetary gear 121 is provided so as to be able to roll around its axis while meshing with the sun gear 120a. A crank pin 112 of the crankshaft 102 is pivotally connected to a rotation center of one side of the planetary gear 121 via a bearing 122, and a gear pin 124 is connected to the other side of the outer periphery of the planetary gear 121. Is projected, and one end 103a of the connecting rod 103 is pivotally connected to the gear pin 124 via a bearing 125.

10, the outer diameter (pitch circle diameter) D _{1 of the} planetary gear 121 is ½ of the inner diameter (pitch circle diameter) D ₂ of the sun gear 120a. Is set to In other words, the outer peripheral length of the planetary gear 121 is set to ½ of the outer peripheral length of the sun gear 120a.

The length L ₁ of the crank arm 111 of the crankshaft 102 (the distance from the axis of the main shaft 110 to the axis of the crankpin 112) and the rotation center O ₂₁ of the planetary gear 121 (the axis of the crankpin 112). ) the distance L ₂ to the connecting point O ₃ (the axis of the gear pin 124) of the connecting rod 103 are set to be equal from. In the illustrated embodiment, the connecting point O ₃ is arranged on the pitch circle of the planetary gear 121.

As a result, the planetary gear 121 rotates twice and rolls once on the sun gear 120 a, and the connection point O ₃ is rotated around the rotation axis O of the crankshaft 102 as the planetary gear 121 rolls. ₂ It is set to reciprocate on a straight line passing through (the axis of the main shaft 110).

In the present embodiment, the other end 103b of the connecting rod 103 is fixedly connected to the center position of the lower surface of the piston 32, so that the axial center X of the piston 32 (the cylindrical inner surface 31a of the cylinder 31). coincides with the axial center) is, together with the passing through the rotation center O ₂ of the crank shaft 102, also the circumferential engagement position between the planetary gear 121 and the sun gear 120a, the axis X of the movement locus of the connecting point O ₃ is the piston 32 Is set to match. As a result, as the planetary gear 121 rolls, the connecting rod 103 swings on the straight line X, that is, on the straight line passing through the rotation center O ₂ of the crankshaft 102 together with the piston 32 (laterally). It will reciprocate linearly without shaking. On the other hand, the crankshaft 102 also rotates around the rotation center O _{2 as the} planetary gear 121 rolls. A relationship between the rotation angle φ of the crankshaft 102 and the stroke S of the piston 32 is represented by a basic form of a sine curve as shown by a solid line in FIG. (The broken line shows the movement of the crank).

Further, the mass distribution of the respective constituent members constituting the crank device 101 is a dynamic balance around the rotation center O ₂ of the crankshaft 102 so that a dynamic balance between the reciprocating motion portion and the rotary motion portion can be obtained. It is set in consideration. In this case, it is preferable that all the counter balancers provided in each component member are set so as to act as a rotational inertia force.

In the illustrated embodiment, in FIG. 11, the mass distribution on both sides of the planetary gear 121 around the rotation center O ₂₁ is equal, and the both sides of the crankshaft 102 around the rotation center O ₂ are centered. The mass distribution is set to be equal.

Specifically, the mass of the reciprocating portion (piston 32 , connecting rod 103, gear pin 124) is W ₁ , the mass of the counterweight (counter balancer) 130 for the reciprocating portion is W ₂ , and the rotational center of the planetary gear 121 The distances from O ₂₁ to the mounting position of the gear pin 124 and the counterweight 130 are A and B, respectively, and the mass of the rotary motion part (the reciprocating motion part, the planetary gear 121, the counterweight 130) is W ₃ . The mass of the counterweight 131 with respect to the rotary motion part is W ₄ , and the distances from the rotational center O ₂ of the crankshaft 102 to the rotational center O ₂₁ of the planetary gear 121 and the mounting position of the counterweight (counter balancer) 131 are C and D, respectively. Then,
W ₁ × A = W ₂ × B (1)
W ₃ × C = W ₄ × D (2)
It is set so that the relationship between the above formulas (1) and (2) is established. In this case, it is assumed that the crank arm 111 and the like have a mass balance on both sides with respect to the rotation center O ₂ in advance.

Thus, in the air compressor 16 including the crank device 101 and the compressed air production unit 33 configured as described above, when the main shaft 110 is rotated by the DC motor 15, the planetary mechanism 104 performs planetary motion and the piston 32 The power is converted into a continuous reciprocating motion, and compressed air is produced in the cylinder 31.

In this case, since the connecting rod 103 is configured as described above, the connecting rod 103 hardly swings in the lateral direction, and is completely integrated with the piston 32 so that the rotation center O ₂ of the crankshaft 102 is set. A reciprocating linear motion is performed on the passing straight line X (the axis of the piston 32 ), and a stable dynamic balance is ensured.

Due to the reciprocating motion of the connecting rod 103 on the straight line X (inclination θ = 0 with respect to the reciprocating direction of the piston 32 ), no eccentric load is generated unlike the conventional crank device. The thrust force in the crank device does not act at all. Therefore, theoretically, piston slap does not occur as in a mechanical device employing a conventional crank device, and the force acting on the cylindrical inner surface 31a of the cylinder 31 is only the frictional force with the piston 32, and vibration, noise, cavitation・ Failures such as friction loss are greatly reduced, and the power transmission efficiency can be greatly improved compared to the conventional one.

  Further, since the planetary gear 121 is disposed so as to be surrounded by the sun gear 120a and the rotational inertia force of the planetary gear 121 is reliably received by the sun gear 120a, the gear efficiency is high, and a stable dynamic balance is also obtained from this point. Secured. Further, due to the rotational inertia force of the planetary gear 121, a close meshing state between the planetary gear 121 and the sun gear 120a is obtained, and the power transmission efficiency is high.

Furthermore, as described above, the mass distribution of each component of the crank device 101 is set in consideration of the dynamic balance around the rotation center O ₂ of the crankshaft 102. Since all the counter balancers 130, 131, etc. provided in each component are set so as to act as a rotational inertia force, uniform and stable operation is ensured from a low speed rotation range to a high speed rotation range.

  In addition, the crank device 101 can be modified in various ways as listed below.

(1) Adjusting the stroke S of the piston 32 with respect to the rotation angle φ of the crankshaft 102 by appropriately adjusting the distance L ₂ from the rotation center O ₂₁ of the planetary gear 121 to the connection point O ₃ of the connecting rod 103; The sine curve of FIG. 12 can be set to an optimal shape for the motion characteristics of the target mechanical device. In this case, the connecting rod 103 and the piston 32 are pivotally connected to each other via a piston pin (not shown) so that the movement trajectory of the connecting rod 103 is not a straight line as in the illustrated embodiment. It becomes a circle or the like that passes in the vicinity of.

For example, by increasing the distance L ₂ , the peak and valley of the sine curve rise and become a sharp curve (see the alternate long and short dash line in FIG. 12). Conversely, by increasing the distance L ₁ , The peaks and valleys become lower and have a gentle curve (not shown).

  (2) The circumferential engagement position between the planetary gear 121 and the sun gear 120a can be adjusted, and the stroke S of the piston 32 can be made variable.

Specifically, for example, the fixed internal gear 120 is provided on the crankcase 114 so as to be adjustable and rotatable in the circumferential direction, and the circumferential position of the sun gear 120a can be adjusted as appropriate. The meshing position with the gear 121 can be relatively adjusted. Also in this case, like the above (1), the connecting rod 103 and the piston 32 are pivotally connected to each other via a piston pin (not shown).

  (3) In the illustrated embodiment, the structure is simplest, large power transmission and high transmission efficiency can be obtained, and the planetary mechanism 104 is composed of a fixed internal gear 120 and a planetary gear 121. However, the present invention is not limited to this, and other structures having a similar meshing function can be employed.

Although not shown, for example, a combination of a sun member chain cylindrical inner peripheral surface of the annular member is provided over the entire circumference, a sprocket wheel as a planetary member meshing with the chain, or an annular member A combination of a sun member in which a toothed belt is provided on the entire inner peripheral surface of the cylinder and a pulley as a planetary member meshing with the toothed belt (timing belt) may be employed.

  (4) Further, as described in (3) above, the engagement between the inner periphery of the solar member and the outer periphery of the planetary member is engaged, and the engagement between the inner periphery of the solar member and the outer periphery of the planetary member is engaged. May be frictional engagements that do not slip each other, and this structure is particularly effective for light load power transmission. Specifically, for example, both the solar member and the planetary member or the engaging surface portion thereof is made of rubber, and frictional engagement between rubbers can be employed.

  In this embodiment, the direct current motor 15 is used for the air compressor 16 and the direct current, which is the output from the solar battery 12, is used directly as a power source. There is no. In addition, by tracking the maximum power point with respect to the amount of solar radiation that changes over time, the power generated by the solar battery 12 can always be maximized and the output of the DC motor 15 can be maximized. In addition, since the output of the solar battery 12 and the output of the DC motor 15 are in a proportional relationship, the output of the DC motor 15 increases when the solar radiation energy increases during operation, but the rated output of the DC motor 15 increases. If it exceeds the above, the heat generation of the motor 15 becomes excessive and dangerous. In the present embodiment, in order to avoid such a state during operation, the constant voltage control is performed on the input voltage to the motor 15, and when the solar radiation energy is excessive, the DC motor 15 is rated. The output is controlled to be constant. In this embodiment, a multi-cylinder air compressor 16 is employed as a means for producing compressed air. By controlling the load of the air compressor 16, the operation can be continued over a wide range with respect to fluctuations in solar radiation energy. For example, when the solar radiation energy is reduced, that is, when the output current of the motor 15 is reduced, the rotational force (torque) necessary for operating the air compressor 16 cannot be obtained, and the rotational speed is reduced. Although the operation is stopped due to the decrease, the unloading valve 27 is opened to reduce the rotational load, so that the rotation can be continued and the production of compressed air can be maintained. On the contrary, when the solar radiation energy becomes large during operation, the opened unload valve 27 can be closed to operate. Furthermore, when the solar radiation energy is large and surplus energy is generated by constant input voltage control, surplus energy (electric power) can be used as another power source.

  The compressed air produced in this way can be stored and used as a power source for an air turbine or the like in an emergency, or can be used as a hybrid power source combined with wind power generation and / or hydroelectric power generation.

As the solar cell 12, a solar cell panel 12P is used, and a plurality of solar cell panels 12P are arranged on the ground surface of the waste accumulation layer 4 by a gantry (not shown). In this case, since there is a wide installation space in the waste disposal site 1, the installation is easy, and a roof that covers at least a part of the ground surface of the waste accumulation layer 4 is configured by a gantry and a solar battery panel 12P. The amount of rainwater that collects rainwater and permeates the waste accumulation layer 4 can be reduced by this roof. Further, as shown in FIG. 15 , solar cell panels 12 </ b> P can be arranged on the ground surface of the waste accumulation layer 4 side by side in the front / rear / left / right direction without any front / rear / left / right gaps.

  Next, the enforcement method of the said vent pipe 5 is demonstrated. The excavator used for the operation includes a rotary drive device 41 that moves up and down the leader provided in the heavy machinery. The rotary excavator 41 press-fits the excavating rod 42 while rotating in the excavating direction, and excavates the waste accumulation layer 4. Drill the hole 7.

  The excavation rod 42 is provided with a plurality of consolidated blade portions 43 on the outer periphery thereof, a spiral excavation blade 44 is provided at the distal end thereof, a plurality of excavation bits 45 are provided at the distal end of the excavation blade 44, and a base end thereof is provided. The extension rods 46 are connected, and the extension rods 46 can be connected to each other. The excavation rod 42 rotates in the same body as the extension rods 46.

  The consolidation blade portion 43 is provided at a plurality of locations (three locations) at substantially equal intervals in the circumferential direction, and is disposed at a spiral position with an interval in the length direction, and is attached to a mounting swash plate 51 inclined in the excavation direction. , 51 are arranged vertically, and a wing body 52 is provided at the outer ends of the upper and lower mounting swash plates 51, 51. The trowel surface 53, which is the outer surface of the wing body 52, has a rotational direction tip at the maximum outer peripheral position 54. A curved shape gradually inward from the maximum outer peripheral position is formed.

The vent pipe 5 described above, smaller than the borehole 7, crushed stone 8 is turned between the borehole 7 and the vent tube 5.

Next, the construction method of the excavation hole 7 of this invention is demonstrated. First, the excavation hole 7 is excavated. The excavation rod 42 is attached to the rotation driving device 41, and the excavation rod 42 is rotated and lowered from the ground surface of the waste accumulation layer 4.

The waste accumulation layer 4 is lowered while excavating the waste accumulation layer 4 by the excavation blades 44 at the tip of the excavation rod 42, while the waste of the waste accumulation layer 4 is excavated in front of the rotating direction of the trowel surface 53 of the consolidation blade portion 43. By rotation of the rod 42, the inner surface of the excavation hole 7 is pressed by the respective trowel surfaces 53, and the waste on the inner surface of the excavation hole 7 is consolidated, whereby the excavation hole 7 is discharged without discharging the waste in the waste accumulation layer 4. Can be formed. Further, excavation is performed using the rod 46 which is added according to the depth of the excavation hole 7.

  When the excavation hole 7 is formed to a predetermined depth, the excavation rod 42 is pulled up to the ground, the vent pipe 5 is inserted into the excavation hole 7, and the crushed stone 8 is filled in the gap between the outer periphery of the vent pipe 5 and the excavation hole 7. Thus, clogging of the vent hole 6 can be prevented by providing the crushed stone filling portion 9 made of the crushed stone 8 on the outer periphery of the vent pipe 5 in a cylindrical shape. In this case, the diameter of the crushed stone filling part 9 is about 650 mm with respect to the diameter of the ventilation pipe 5 being about 350 mm, and thus the diameter of the crushed stone filling part 9 is 1.5 times or more the diameter of the ventilation pipe 5. By making it twice or less, the air permeability between the vent pipe 5 and the waste object stack 4 can be ensured satisfactorily. In this case, even if it exceeds 3 times, the clogging prevention effect does not change, and conversely, the excavation hole 7 becomes unnecessarily large and the construction cost increases, so 3 times or less is preferable. In addition, as the crushed stone 8, in order to ensure air permeability, 20-60 mm single particle size crushed stone, preferably 30-50 mm single particle size crushed stone is used.

  In this way, the plurality of ventilation pipes 5 are installed, and all or a part of the plurality of ventilation pipes 5 are connected to the compressed air production apparatus 11 by the air supply pipe 61. In this case, the air supply pipe 61 is connected to the air tank 35 via the valve 62.

  Then, the compressed air production apparatus 11 is driven by the solar cell 12, the air is pumped from the air compressor 16 to the vent pipe 61, and the air is fed into the waste accumulation layer 4 from the plurality of vent holes 6. Decomposition is promoted and waste is stabilized. In this case, when the compressed air producing apparatus 11 is partially connected to the plurality of vent holes 5, the vent pipe 5 not connected to the compressed air producing apparatus 11 becomes an exhaust pipe and is generated by aerobic decomposition. Gas can be exhausted.

  As described above, in this embodiment, in the stabilization promoting device in the waste disposal site in which the waste accumulation layer 4 is provided with the vent pipe 5, the compressed air production apparatus 11 serving as the air feeding means is connected to the vent pipe 5, and the compressed air is supplied. Since the driving source of the manufacturing apparatus 11 is the solar battery 12, the compressed air manufacturing apparatus 11 is driven by the electric power generated by the solar battery 12, and the air sent from the compressed air manufacturing apparatus 11 to the vent pipe 5 is a waste accumulation layer. 4, aerobic decomposition is promoted in the waste accumulation layer 4, and early stabilization becomes possible. And the waste disposal site 1 has a vast unused plane, and can install many solar cell panels easily.

  In this way, in this embodiment, surplus power generated by the solar cell 12 is used for either power sales, a drive source of other facilities in the waste disposal site, or power storage, so that surplus power can be used effectively. Can do.

  As described above, in the present embodiment, the compressed air production apparatus 11 serving as the air supply means includes the compressed air produced by the compressed air production unit 33 including the solar cell 12 that converts sunlight into electrical energy, the cylinder 31, and the piston 32. In a compressed air production apparatus comprising: an air compressor 16 that produces a direct current motor 15 that is a drive motor of the air compressor 16 that is driven by the output of the solar battery 12, and a control means 17 that drives and controls the air compressor 16. The air compressor 16 is a multi-cylinder type having a plurality of compressed air production units 33, and the control means 17 compresses the compressed air to produce compressed air, for example, when the output of the solar cell 12 falls below a predetermined value due to a change in the illuminance of sunlight. Since control is performed to change the number of air production units 33, when the solar radiation decreases and the illuminance decreases, the output current of the solar cell 12 decreases, and the power required to drive the DC motor 15 is reduced. Obtained Therefore, for example, when the output of the solar battery 12 is equal to or less than a predetermined value, the control means 17 is changed so as to reduce the number of compressed air production units 33 that generate compressed air, thereby reducing the load on the DC motor 15. , Stable driving can be continued. When the output of the solar cell 12 increases and exceeds the predetermined value, the number of compressed air production units 33 that produce compressed air can be increased to efficiently use solar radiation for the production of compressed air.

  Further, in this embodiment, the excavation rod 42 is formed in the waste accumulation layer 4 of the waste disposal site 1 without using the excavation rod 42 to discharge the waste, and then the excavation rod 42 is pulled out. A vent pipe 5 having a plurality of vent holes 6 is stood in the hole 7, and a compressed air production apparatus 11 is connected to the vent pipe 5 to form the excavation hole 7 without discharging the waste in the waste accumulation layer 4. This eliminates the need for disposal of waste generated during excavation.

  In this way, in this embodiment, the excavation rod 42 is provided with a plurality of consolidated wing portions 43 provided with a trowel surface 53 from the outer circumference of the rod to the excavation diameter, so that when the excavation rod 42 rotates, the excavation rod 42 is excavated. The waste surface is pressed against the inner surface of the excavation hole 7 by the trowel surface 53, and the inner surface of the excavation hole 7 is consolidated, thereby eliminating the need to discharge the excavated waste to the ground surface.

  Further, in this embodiment, after the excavation hole 7 is formed, the vent pipe 5 having an outer diameter smaller than that of the excavation hole 7 is inserted into the excavation hole 7. Since the crushed stone 8 is inserted to form the crushed stone filling portion 9, the inner surface of the excavation hole 7 is consolidated by the excavation rod 42, so that even if the vent pipe 5 smaller than the excavation hole 7 is inserted, the excavation hole 7 The crushed stone filling portion 9 can be formed by filling the crushed stone 8 between the excavation hole 7 and the ventilation pipe 5 without securing the crushed stone filling portion 9. Can do.

  Hereinafter, as an effect on the embodiment, the vent pipe 5 is smaller than the excavation hole 7 and the crushed stone 8 is introduced between the excavation hole 7 and the vent pipe 5. Clogging of the air holes 6 can be prevented.

  Further, a plurality of vent pipes 5 are arranged at the intersections of the meshes, and one of the adjacent vent pipes 5 is connected to the compressed air production apparatus 11 in the vertical and horizontal directions of the grid, and the other adjacent vent pipe 5 is connected to the waste accumulation layer. Since the exhaust pipe for exhausting the gas in 4 to the outside is provided, the supply of air to the waste accumulation layer 4 and the exhaust of the generated gas can be performed efficiently, and early stabilization becomes possible.

  Further, by setting the diameter of the crushed stone filling portion 9 to 1.5 times or more the diameter of the vent pipe 5, the air permeability between the vent pipe 5 and the waste object stack 4 can be ensured satisfactorily.

  The compressed air production unit 33 has an unload valve 37 for no-load operation, and the number of compressed air production units 33 that create the compressed air by opening the unload valve 37 is changed. The opened compressed air production unit 33 is in a no-load operation, and can reduce the load on the DC motor 15 without stopping the operation of the piston 32 separately.

  Further, since the drive motor is the DC motor 15, the DC power that is the output of the solar battery 12 can be directly supplied to the DC motor 15. Therefore, DC / AC conversion is unnecessary, and the loss associated with the conversion is eliminated.

  In addition, since the maximum output point tracking device 14 that tracks the maximum point of the output of the solar cell 12 is provided, the output of the solar cell 12 is obtained by tracking the maximum power point with respect to the output of the solar cell 12 that changes due to solar radiation. Can be kept to the maximum.

  Also, if the output of the solar battery 12 exceeds the rated output of the DC motor 15, the DC motor 15 is driven at the rated output. Excessive heat generation of the motor 15 can be prevented, and the portion exceeding the rated output can be used for charging or the like.

The crank device 101 used for the air compressor 16 is a device applied to a power conversion part of reciprocating motion and rotational motion, and is connected to a crankshaft 102 connected to the rotating side and connected to the reciprocating motion side. a rod 103, made and a planetary mechanism 104 interposed between the crank shaft 102 and connecting rod 103, the planetary mechanism 104, the rotation center O ₂₁ of the crank shaft 102 coaxially and rotatably adjustably disposed And a planetary gear 121 that is a planetary member that rolls along the inner periphery of the fixed internal gear 120, and the outer diameter D ₁ of the planetary gear 121 is the inner diameter of the fixed internal gear 120. is set to 1/2 of the D _2, on one side of the rotational center O ₂₁ of the planetary gear 121, together with the crankpin 112 of the crankshaft 102 is pivotally connected rotatably, on the outer peripheral portion the other side of the planet gears 121 The one end 103a of the connecting rod 103 is pivotally connected via a pin, The trajectory of the reciprocating motion of the one end 103a of the connecting rod 103 traverses the circular rotational trajectory of the crank pin 112, and the mass distribution of each of the above components is such that a dynamic balance is achieved between the reciprocating motion portion and the rotational motion portion. Since the circumferential engagement position between the planetary gear 121 and the fixed internal gear 120 can be adjusted by adjusting the rotation of the fixed internal gear 120 as necessary, the connecting rod 103 can be swung almost horizontally. Without moving, the piston 32 moves substantially linearly with the piston 32 in the reciprocating direction of the piston 32 to ensure a stable dynamic balance.

In particular, the length L ₁ of the crank arm 111 of the crankshaft 102 and the distance L ₂ from the rotation center O ₂₁ of the planetary gear 121 to the connecting point of the connecting rod 103 are set equal to each other. If it is set so as to move along a straight line passing through the rotation center O ₂ of the crankshaft 102 with rolling, the connecting rod 103 does not swing at all and cannot swing sideways. It disappears at all.

  Moreover, the planetary gear 121 is disposed so as to surround the fixed internal gear 120, and the rotational inertia force of the planetary gear 121 is reliably received by the fixed internal gear 120. From this point as well, a stable dynamic balance is ensured. In addition, a close engagement state between them can be obtained, and the power transmission efficiency can be improved.

  Further, since the mass distribution of each component is set in consideration of the dynamic balance around the rotation center of the crankshaft 102, uniform and stable operation from the low speed rotation range to the high speed rotation range is ensured. The In this case, in particular, it is preferable that all the counter balancers provided in the constituent members are set so as to work as a rotational inertia force.

  FIG. 16 shows a second embodiment of the present invention, in which the same parts as those in the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted. In this example, the solar cell panel 12P is disposed above the vent hole 5, and the solar cell panel 12P covers the upper portion of the vent hole 5. The solar panel 12P is arranged obliquely facing the sun.

  Therefore, even when it rains, rainwater does not directly enter the vent hole 5 by the solar cell panel 12P, and air permeability can be ensured. The rainwater falling on the solar cell panel 12P follows the inclination of the solar cell panel 12P. To the ground surface away from the vent hole 5.

  The present invention is not limited to this embodiment, and various modifications can be made within the scope of the gist of the present invention. For example, in the embodiment, the compressed air manufacturing apparatus is connected to the vent pipe via a valve. However, the air compressor of the compressed air manufacturing apparatus may be connected to the vent pipe by an air supply pipe without using the valve and the air tank. . Moreover, although the Example demonstrated the air compressor provided with two air compressed air manufacturing parts, it is good also as three or more air compressed air manufacturing parts.
