Description

Technical Field

[0001] This invention relates to the field of new energy prefabricated substation technology, specifically a new energy prefabricated substation that is resistant to wind and sand and salt spray corrosion. Background Technology

[0002] A new energy prefabricated substation is a type of equipment that combines high-voltage switchgear, distribution transformers, low-voltage distribution devices, reactive power compensation devices, power metering devices, and auxiliary equipment into one or more compact sets of power distribution equipment according to a certain wiring scheme. The whole unit is enclosed in a fully enclosed metal shell and has the main functions of a substation. It is suitable for outdoor installation and use.

[0003] For example, Chinese patent CN121440379A discloses a new energy box-type substation that is resistant to wind and sand and salt spray corrosion. It includes protective boxes symmetrically arranged on both sides of the box-type substation, and also includes: a wind guiding mechanism for air conduction inside the box-type substation, a dividing mechanism for dividing the internal space of the protective box, a protective mechanism for assisting the protective box in protecting the inside of the box-type substation, and a blocking mechanism for controlling the opening or closing of the wind guiding pipe.

[0004] In the aforementioned patent, external air is initially filtered through ventilation holes before entering the protective box. It flows within the protective cavity and transfer cavity formed by the partition plate. Larger particles of sand and other impurities are blocked by the protective cavity and settle in the dust collection box at the bottom. However, the above solution has the following shortcomings: when the sandstorm in the external environment increases, the airflow will carry more sand and salt spray particles to the filter plate. When the filter plate becomes blocked, the amount of air entering the box-type substation decreases, resulting in a lower heat dissipation effect on the electrical components inside the box-type substation. Therefore, we have introduced a new energy box-type substation that is resistant to sandstorms and salt spray corrosion. Summary of the Invention

[0005] The purpose of this invention is to provide a new energy box-type substation that is resistant to wind and sand and salt spray corrosion, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A new energy prefabricated substation designed to resist wind, sand, and salt spray corrosion includes a prefabricated substation with connecting seats installed at both ends. Each connecting seat has an air guide cavity, and several air guide plates are movably connected within the air guide cavity. A first filter mechanism is provided on one side of each air guide plate and connected to the air guide cavity. A wind-powered transmission mechanism is connected to the upper end of the prefabricated substation, and the lower end of the wind-powered transmission mechanism extends into a circular cavity and connects to a connecting block. The connecting block is located within the circular cavity. When wind from the external environment comes into contact with the wind-powered transmission mechanism, the wind-powered transmission mechanism drives the connecting block to rotate.

[0008] A counterweight is movably connected to one end of the connecting block, and a compression wheel is movably connected to the end of the counterweight away from the connecting block. An annular storage bladder is fixedly connected inside the circular cavity, and the annular storage bladder stores transmission oil. A gear is fixedly connected to one end of the air guide plate, and several gears are connected to a first transmission mechanism. The first transmission mechanism is located inside the connecting seat and is connected to the inside of the annular storage bladder through a guide cavity. The guide cavity is located inside the connecting seat. The compression wheel compresses the annular storage bladder, causing the transmission oil inside the annular storage bladder to push the first transmission mechanism along the guide cavity. The first transmission mechanism drives several gears to rotate, causing several air guide plates to rotate.

[0009] The connecting seat is equipped with a pulling mechanism. One end of the pulling mechanism extends into the circular cavity, and the other end is connected to the first filter mechanism. When the connecting block rotates, it squeezes the pulling mechanism, causing the pulling mechanism to drive the first filter mechanism to vibrate. Several inclined plates are fixedly connected inside the air guide cavity. A second filter mechanism is provided inside the air guide cavity. The two ends of the second filter mechanism extend into corresponding connecting boxes. Two connecting boxes are fixedly connected to the outside of the connecting seat. A plug pipe is fixedly connected to the outside of the connecting seat. The inside of the plug pipe is connected to the air guide cavity. An exhaust fan is installed inside the plug pipe. An airflow detection mechanism is provided on the upper side of the second filter mechanism. The airflow detection mechanism is installed inside the air guide cavity and detects the amount of airflow passing through the second filter mechanism.

[0010] Preferably, the first filtration mechanism includes a first filter plate, which is rotatably connected to the air guide cavity. Guide rods are fixedly connected to both ends of the first filter plate. The guide rods are slidably connected to guide grooves, which are opened in the air guide cavity. A guide rod is slidably connected inside the guide rod, and both ends of the guide rod are fixedly connected to the guide grooves. A support spring is sleeved on the outside of the guide rod, with one end of the support spring fixedly connected to the guide groove and the other end fixedly connected to the guide rod.

[0011] Preferably, the wind power transmission mechanism includes a T-shaped connecting column, which is movably connected to the upper end of the connecting seat. A first rotating shaft and a second rotating shaft are movably connected inside the T-shaped connecting column. A bevel gear is fixedly connected to the opposite end of the first rotating shaft and the second rotating shaft. The two bevel gears mesh with each other. The end of the first rotating shaft away from the bevel gear extends into the external environment and is fixedly connected to the fan. The lower end of the second rotating shaft extends into a circular cavity and is fixedly connected to the connecting block.

[0012] Preferably, the connecting block has a first square cavity, and a first T-shaped rod is slidably connected in the first square cavity. One end of the first T-shaped rod extends into the circular cavity and is fixedly connected to the counterweight. A first spring is sleeved on the outside of the first T-shaped rod. One end of the first spring is fixedly connected to the first T-shaped rod, and the other end is fixedly connected to the first square cavity.

[0013] Preferably, the first transmission mechanism includes a T-shaped rack, the outer side of which meshes with several gears, the upper end of which slides into a connecting cavity, the connecting cavity being opened in a connecting seat, the connecting cavity communicating with the inner side of the annular storage bladder through a guide cavity, and a second spring fixedly connected to the upper end of the T-shaped rack, the upper end of which is fixedly connected to the connecting cavity.

[0014] Preferably, the pulling mechanism includes a second T-shaped rod, which slides within a second square cavity. The second square cavity is located within a connecting seat. The upper end of the second T-shaped rod extends into a circular cavity and is fixedly connected to a ball bearing. A pull rope is fixedly connected to the outer side of the second T-shaped rod and is movably connected within the connecting seat. The end of the pull rope away from the second T-shaped rod extends into the air guide cavity and is fixedly connected to the first filter plate. A third spring is fixedly connected to the lower end of the second T-shaped rod, and the lower end of the third spring is fixedly connected to the second square cavity.

[0015] Preferably, the second filtration mechanism includes a slide plate slidably connected to the air guide cavity. The slide plate has several mounting slots, in which a second filter plate is installed. Both ends of the slide plate extend into corresponding connecting boxes. A transmission screw is screwed into the slide plate, and both ends of the transmission screw are movably connected to the inside of two connecting boxes. A transmission motor is fixedly connected to the outside of one connecting box, and the output end of the transmission motor is fixedly connected to one end of the transmission screw. A box cover is installed on the upper end of the connecting box, and a protective cover is fitted onto the outside of the transmission motor, with the protective cover installed on the outside of the corresponding connecting box.

[0016] Preferably, the airflow detection mechanism includes a micro switch, the pressing end of which is fixedly connected to a baffle plate, and the lower end of the connecting seat is equipped with a discharge plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: When the external environment is windy, the wind power transmission mechanism will rotate to the direction of the wind. The wind power transmission mechanism drives the connecting block to rotate, so that the counterweight continuously squeezes the pulling mechanism. At this time, the first filter mechanism shakes back and forth, shaking off the filter material on the surface of the first filter mechanism. When the wind speed of the external environment increases, the rotation speed of the connecting block increases, and the counterweight moves outward to cancel the continuous squeezing of the pulling mechanism. The compression wheel connected to the outside of the counterweight squeezes the annular storage bladder, so that the transmission oil in the annular storage bladder pushes the first transmission mechanism to move along the guide cavity. The first transmission mechanism drives several gears to rotate, so that several wind guide plates rotate to block the wind guide cavity, preventing the airflow from carrying a large amount of sand and salt spray particles into the air during strong winds.

[0018] The airflow detection mechanism detects the airflow through the second filtration mechanism. When the detected airflow decreases, the second filtration mechanism will move to replace the filter surface to prevent the filter plate from becoming clogged, which would reduce the amount of air entering the prefabricated substation and thus reduce the heat dissipation effect of the prefabricated substation.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-15 The present invention provides a technical solution:

[0037] Example 1:

[0038] A new energy prefabricated substation with wind and sand protection and salt spray corrosion protection includes a prefabricated substation 1. The prefabricated substation 1 is used to install new energy electrical components. Both ends of the prefabricated substation 1 are equipped with connecting seats 2. During use, the exhaust fans 16 in the two connecting pipes 7 can be controlled to rotate in opposite directions according to the usage conditions, so that the air guide cavity 45 in one connecting seat 2 is used for air intake and the air guide cavity 45 in the other connecting seat 2 is used for air exhaust. The connecting seat 2 has an air guide cavity 45 for guiding airflow. Several air guide plates 3 are movably connected in the air guide cavity 45. Several limiting plates are provided in the air guide cavity 45. The positions of the several limiting plates 45 correspond to the positions of the several air guide plates 3. Through the setting of several limiting plates, the air guide plates 3 stop when they rotate to the position that blocks the air guide cavity 45.

[0039] A first filter mechanism is provided on one side of several air guide plates 3. The first filter mechanism is connected to the air guide cavity 45. The first filter mechanism filters sand particles in the airflow. The upper end of the box-type substation 1 is connected to a wind power transmission mechanism. The lower end of the wind power transmission mechanism extends into the circular cavity 21 and is connected to the connecting block 33. The connecting block 33 is set in the circular cavity 21. When the wind in the external environment comes into contact with the wind power transmission mechanism, the wind power transmission mechanism drives the connecting block 33 to rotate.

[0040] One end of the connecting block 33 is movably connected to a counterweight 30, and the other end of the counterweight 30 away from the connecting block 33 is movably connected to a compression wheel 31. An annular storage bladder 17 is fixedly connected inside the circular cavity 21. The annular storage bladder 17 can be used with fluororubber or hydrogenated nitrile rubber in extreme temperature and harsh chemical environments. The annular storage bladder 17 stores transmission oil, which can be hydraulic oil or other liquids that can be used as transmission media. One end of the air guide plate 3 is fixedly connected to a gear 36. Several gears 36 are connected to the first transmission mechanism. The first transmission mechanism is located in the connecting seat 2 and is connected to the inside of the annular storage bladder 17 through a guide cavity 44. The guide cavity 44 is located in the connecting seat 2. The compression wheel 31 compresses the annular storage bladder 17, causing the transmission oil in the annular storage bladder 17 to move along the guide cavity 44 and drive the first transmission mechanism to move. The first transmission mechanism drives several gears 36 to rotate, causing several air guide plates 3 to rotate.

[0041] The connecting seat 2 is equipped with a pulling mechanism. One end of the pulling mechanism extends into the circular cavity 21, and the other end is connected to the first filter mechanism. When the connecting block 33 rotates, it squeezes the pulling mechanism, causing the pulling mechanism to shake the first filter mechanism, which shakes off the sand particles adhering to the surface of the first filter mechanism. Several inclined plates 13 are fixedly connected in the air guide cavity 45. After the airflow enters the air guide cavity 45, the airflow collides with the several inclined plates 13, which blocks the sand particles in the airflow.

[0042] The air guide cavity 45 is equipped with a second filter mechanism. The two ends of the second filter mechanism extend into the corresponding connecting boxes 9 respectively. The second filter mechanism blocks the salt spray particles in the airflow. The two connecting boxes 9 are fixedly connected to the outside of the connecting seat 2. The connecting seat 2 is fixedly connected to the outside of the connecting pipe 7. The inside of the connecting pipe 7 is connected to the air guide cavity 45. An exhaust fan 16 is installed inside the connecting pipe 7. The exhaust fan 16 is fixedly connected to the output end of the motor. The motor is installed on the horizontal plate inside the connecting pipe 7. The motor drives the exhaust fan 16 to rotate, so that the outside air enters the air guide cavity 45.

[0043] An airflow detection mechanism is provided on the upper side of the second filtration mechanism. The airflow detection mechanism is installed inside the air guide cavity 45 and detects the size of the airflow passing through the second filtration mechanism.

[0044] Example 2:

[0045] Based on Example 1, in order to prevent a large number of sand particles from clogging the first filter plate 22 during windy weather, such as Figure 13 As shown, the first filtration mechanism includes a first filter plate 22, which is made of a corrosion-resistant material, such as stainless steel. The first filter plate 22 is rotatably connected to the air guide cavity 45. When the first filter plate 22 rotates, its upper end rotates along the air guide cavity 45 and is tightly fitted to the air guide cavity 45. Guide rods 42 are fixedly connected to both ends of the first filter plate 22. The guide rods 42 are slidably connected to the guide groove 46, which is opened in the air guide cavity 45. A guide rod 10 is slidably connected inside the guide rod 42. Both ends of the guide rod 10 are fixedly connected to the guide groove 46. A support spring 43 is sleeved on the outside of the guide rod 10. One end of the support spring 43 is fixedly connected to the guide groove 46, and the other end is fixedly connected to the guide rod 42. The guide rod 10 limits the support spring 43 to prevent the support spring 43 from disengaging from the guide groove 46 when the guide rod 42 moves along the guide groove 46.

[0046] like Figure 6 , 11As shown, the wind power transmission mechanism includes a T-shaped connecting rod 6. A tail fin is fixedly connected to the outside of the T-shaped connecting rod 6. The tail fin causes the fan 4 to rotate in the direction of the wind. The T-shaped connecting rod 6 is movably connected to the upper end of the connecting seat 2. The T-shaped connecting rod 6 is rotatably connected to the upper end of the connecting seat 2. A first rotating shaft 19 and a second rotating shaft 18 are movably connected inside the T-shaped connecting rod 6. A bevel gear 20 is fixedly connected to the opposite ends of the first rotating shaft 19 and the second rotating shaft 18. The two bevel gears 20 mesh with each other. The end of the first rotating shaft 19 away from the bevel gear 20 extends into the external environment and is fixedly connected to the fan 4. The second rotating shaft... The lower end of 18 extends into the circular cavity 21 and is fixedly connected to the connecting block 33. When the external environment is windy, the number of sand particles in the airflow entering the air guide cavity 45 increases. The outer side of the T-shaped connecting column 6 is connected to the tail fin. The lower end of the T-shaped connecting column 6 is rotatably connected to the upper end of the connecting seat 2. Therefore, under the guidance of the tail fin, the fan 4 will rotate in the direction of the wind. When the fan 4 rotates, it drives the first rotating shaft 19 to rotate. The first rotating shaft 19 drives the bevel gear 20 to rotate. At this time, the other bevel gear 20 will follow and rotate. At this time, the second rotating shaft 18 will start to rotate. The rotation of the second rotating shaft 18 drives the connecting block 33 to rotate.

[0047] like Figure 6 , 7 As shown, a first square cavity 32 is provided inside the connecting block 33. A first T-shaped rod 35 is slidably connected inside the first square cavity 32. One end of the first T-shaped rod 35 extends into the circular cavity 21 and is fixedly connected to the counterweight 30. The counterweight 30 can be selected according to the usage situation. A first spring 34 is sleeved on the outside of the first T-shaped rod 35. One end of the first spring 34 is fixedly connected to the first T-shaped rod 35, and the other end is fixedly connected to the first square cavity 32. When encountering strong winds, the rotation speed of the fan 4 increases, and the rotation speed of the connecting block 33 also increases. Under the action of centrifugal force, the high-speed connecting block 33 will cause the counterweight 30 to be thrown outward. At this time, the first T-shaped rod 35 moves along the first square cavity 32, the first spring 34 is compressed, and after the counterweight 30 is thrown outward, the rotating counterweight 30 cannot press the second T-shaped rod 25.

[0048] like Figure 10 , 15As shown, the first transmission mechanism includes a T-shaped rack 38, the outer side of which meshes with several gears 36. A cavity is provided inside the connecting seat 2 to accommodate the gears 36 and the lower end of the T-shaped rack 38. The lower end of the T-shaped rack 38 extends into this cavity and meshes with the gears 36. The upper end of the T-shaped rack 38 slides within the connecting cavity 5, which is located within the connecting seat 2. The connecting cavity 5 communicates with the inner side of the annular storage bladder 17 via a guide cavity 44. A second spring 37 is fixedly connected to the upper end of the T-shaped rack 38, and the upper end of the second spring 37 is fixedly connected to the connecting cavity 5. When encountering strong winds, the rotation speed of the fan 4 increases, and the connecting block 33... The rotation speed also increases. Under the action of centrifugal force, the high-speed connecting block 33 will cause the counterweight 30 to be thrown outward. At this time, the first T-shaped rod 35 moves along the first square cavity 32, the first spring 34 is compressed, and after the counterweight 30 is thrown outward, the rotating counterweight 30 cannot press the second T-shaped rod 25. When the counterweight 30 is thrown outward, the extrusion wheel 31 located at one end of the counterweight 30 will contact the annular storage bladder 17. As the counterweight 30 moves, the extrusion wheel 31 will extrude the annular storage bladder 17. The transmission oil located in the annular storage bladder 17 enters the connecting cavity 5 through the guide cavity 44.

[0049] like Figure 6 , 13 As shown, the pulling mechanism includes a second T-shaped rod 25, which is slidably connected to a second square cavity 23. The second square cavity 23 is opened in the connecting seat 2. The upper end of the second T-shaped rod 25 extends into the circular cavity 21 and is fixedly connected to a ball bearing 26. A pull rope 27 is fixedly connected to the outside of the second T-shaped rod 25. The pull rope 27 can be made of a corrosion-resistant material, such as stainless steel. The pull rope 27 is movably connected to the connecting seat 2. The end of the pull rope 27 away from the second T-shaped rod 25 extends into the air guide cavity 45 and is fixedly connected to the first filter plate 22. A third spring 24 is fixedly connected to the lower end of the second T-shaped rod 25. The lower end of the third spring 24 is fixedly connected to the second square cavity 23.

[0050] like Figure 9 , 14As shown, the second filtration mechanism includes a slide plate 14, which is slidably connected to the air guide cavity 45. Several mounting slots 39 are provided in the slide plate 14, and a second filter plate 29 is installed in the mounting slots 39. The second filter plate 29 is made of a material that filters salt spray particles, such as a glass fiber filter or a fluoropolymer-based composite fiber filter. Both ends of the slide plate 14 extend into the corresponding connecting boxes 9. A transmission screw 40 is screwed into the slide plate 14. Both ends of the transmission screw 40 are movably connected to the inside of two connecting boxes 9. A transmission motor 41 is fixedly connected to the outside of one connecting box 9. The output end of the transmission motor 41 is fixedly connected to one end of the transmission screw 40. A box cover 8 is installed on the upper end of the connecting box 9. A protective cover 11 is sleeved on the outside of the transmission motor 41. The protective cover 11 is installed on the outside of the corresponding connecting box 9.

[0051] like Figure 12 As shown, the airflow detection mechanism includes a micro switch 15. When using the micro switch 15, the appropriate size and model can be selected according to the usage. The pressing end of the micro switch 15 is fixedly connected to a baffle plate 28, and the lower end of the connecting seat 2 is equipped with a discharge plate 12.

[0052] The springs in this application can be made of corrosion-resistant materials, such as stainless steel, during use.

[0053] Working principle: During use, two connecting seats 2 are installed at both ends of the box-type substation 1 by screws. During installation, the plug pipe 7 is inserted into the inside of the box-type substation 1 through the hole opened on the outside of the box-type substation 1. Under normal conditions, the second spring 37 pushes the T-shaped toothed rod 38 to move downward. The movement of the T-shaped toothed rod 38 drives the gear 36 to rotate. The rotation of the gear 36 drives the air guide plate 3 to rotate. At this time, several air guide plates 3 are set in an inclined position. Through the rotation of the exhaust fan 16, the airflow is guided into the air guide cavity 45 through the air guide plate 3. When the sand particles in the airflow hit the inclined air guide plate 3, they will be blocked for the first time. The airflow entering the air guide cavity 45 first passes through the first filter plate 22. The first filter plate 22 can block the smaller sand particles in the airflow. Then the airflow passes through several inclined plates 13 along the air guide cavity 45. The several inclined plates 13 set in an inclined position block the sand particles in the airflow again.

[0054] The airflow then continues to move through the second filter plate 29, which can block the salt spray particles in the airflow. The completely filtered airflow enters the box-type substation 1 for heat dissipation. After that, the airflow is discharged back into the external environment through the air guide cavity 45 in another connecting seat 2.

[0055] When the airflow passes through the second filter plate 29, the upward airflow pushes the baffle plate 28 upward. The movement of the baffle plate 28 causes the pressing end of the micro switch 15 to press the micro switch 15. When the second filter plate 29 is blocked in a large area, causing the airflow to decrease, the airflow passing through the second filter plate 29 can no longer push the baffle plate 28 upward. At this time, the pressing end of the micro switch 15 releases the pressure. After the micro switch 15 is released, the processor controls the drive motor 41 to rotate. The drive screw 40 located at the output end of the drive motor 41 is driven to start rotating. The rotation of the drive screw 40 drives the slide plate 14 to move. The movement of the slide plate 14 moves the new second filter plate 29 into the air guide cavity 45. At the same time, the old second filter plate 29 will move into a connecting box 9. The old second filter plate 29 can be removed by opening the box cover 8 at the top of the connecting box 9. Then, the new second filter plate 29 can be installed in the mounting slot 39 by screws.

[0056] When the external environment is windy, the number of sand particles in the airflow entering the air guide cavity 45 increases. The tail fin is connected to the outside of the T-shaped connecting column 6, and the lower end of the T-shaped connecting column 6 is rotatably connected to the upper end of the connecting seat 2. Therefore, under the guidance of the tail fin, the fan 4 will rotate in the direction of the wind. When the fan 4 rotates, it drives the first rotating shaft 19 to rotate. The first rotating shaft 19 drives the bevel gear 20 to rotate. At this time, the other bevel gear 20 will follow and rotate. At this time, the second rotating shaft 18 will start to rotate. The rotation of the second rotating shaft 18 drives the connecting block 33 to rotate. The rotation of the connecting block 33 drives the counterweight block 30 to rotate. During the rotation of the counterweight block 30, it will contact the ball 26 at the upper end of the second T-shaped rod 25. At this time, as the counterweight block 30 rotates, the second T-shaped rod 25 will be squeezed downward by the counterweight block 30 and move downward. At this time, the third spring 24 is compressed.

[0057] The second T-shaped rod 25 moves downward to pull the pull rope 27, which in turn pulls the first filter plate 22. At this time, the guide rods 42 connected to both ends of the first filter plate 22 move along the guide groove 46, and the support spring 43 is compressed. When the connecting block 33 continues to rotate and does not press the second T-shaped rod 25, the second T-shaped rod 25 moves upward under the elastic force of the third spring 24, and the pull rope 27 is released from pulling. At the same time, under the elastic force of the support spring 43, the first filter plate 22 returns to its initial position. When the counterweight 30 presses the second T-shaped rod 25 again, the pull rope 27 will pull the first filter plate 22 again, so that the first filter plate 22 can shake back and forth in windy weather, thereby shaking off the sand particles on the surface of the first filter plate 22.

[0058] When encountering strong winds, the fan 4 rotates at a higher speed, and the connecting block 33 also rotates faster. Under the action of centrifugal force, the high-speed connecting block 33 causes the counterweight 30 to be thrown outward. At this time, the first T-shaped rod 35 moves along the first square cavity 32, the first spring 34 is compressed, and after the counterweight 30 is thrown outward, the rotating counterweight 30 can no longer press the second T-shaped rod 25. When the counterweight 30 is thrown outward, the compression wheel 31 located at one end of the counterweight 30 will interact with the annular storage ring. When the storage bladder 17 comes into contact with the counterweight 30, the compression wheel 31 will compress the annular storage bladder 17. The transmission oil in the annular storage bladder 17 enters the connecting cavity 5 through the guide cavity 44. The transmission oil entering the connecting cavity 5 pushes the T-shaped rack 38 to move upward. The movement of the T-shaped rack 38 drives several gears 36 to rotate. The rotating gears 36 cause the air guide plate 3 to flip and block the air inlet position of the air guide cavity 45, preventing the airflow from carrying a large amount of sand and salt spray particles into the air during strong winds.

[0059] When the strong winds end, the first T-shaped rod 35 retracts back into the first square cavity 32 under the elastic force of the first spring 34. At this time, the counterweight 30 returns to its initial position. Under the elastic force of the second spring 37, the T-shaped toothed rod 38 moves downward along the connecting cavity 5, allowing the transmission oil to re-enter the annular storage bladder 17 through the guide cavity 44. At the same time, the downward movement of the T-shaped toothed rod 38 causes the air guide plate 3 to rotate again and be set in an inclined state.

[0060] The unloading plate 12 can be removed by opening the screw that installs it, allowing the filtered sand particles in the air guide cavity 45 to be discharged. After discharge, the unloading plate 12 can be reinstalled at the lower end of the connecting seat 2 by using the screw.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
