Description

[0002] With the rapid development of the economy, energy consumption has become an urgent problem to be solved, so people have put forward higher requirements for the development of modern industrial technology. Compressed air energy storage is a new energy storage technology. In order to improve the sealing of artificial chamber energy storage, sealants are used to seal the chamber. Silicone sealant materials have the functions of anti-leakage, waterproof, anti-aging and heat insulation.

[0003] However, in the prior art, there are many defects in the use of sealing devices for chamber energy storage: 1. The sealant device nozzle is fixed, which makes it difficult to spray on hidden parts such as corners. The action direction is single and cannot adapt to various working conditions, which reduces the overall effect of sealant spraying; 2: There is no automatic stirring function. For example, two-component glue needs to be stirred manually or with the help of tools, which increases the labor intensity and reduces the work efficiency. 3: Use traditional manual glue guns to apply glue, which cannot ensure the uniformity of the sealant and has low efficiency. Repeated scraping is required to achieve the gluing requirements, which increases manual labor.

One end of the adapter 5 is detachably connected to the end of the channel seat 8 located outside the shell 1, and the end of the channel seat 8 located inside the shell 1 is connected to the material storage part. The adapter 5 forms a contact surface with the left end of the shell 1, and the nozzle 6 is detachably connected to the other end of the adapter 5. A straight jet passage 9 is opened on the adapter 5, and an annular air passage 10 is opened at one end of the adapter 5, and the annular air passage 10 is connected to the straight jet passage 9. The adapter 5 and the inner and outer sides of the annular air passage 10 are respectively embedded with sealing rings 7, and the sealing ring 7 is also in contact with the left end of the shell 1. An air passage seat 11 with a through hole is opened at the left end of the shell 1, and one end of the air passage seat 11 is connected to the annular air passage 10, and the other end of the air passage seat 11 is connected to the jetting part.

[0030] In actual use: the sealant enters the adapter 5 through the channel seat 8, and is then sprayed out through the nozzle 6 to perform the sealant spraying operation. Before spraying, the jet part is started, and the airflow enters the annular airway 10 through the airway seat 11, and then the airflow enters the straight jet channel 9 through the annular airway 10 and is sprayed out, and then purging can be performed.

[0031] The annular air passage 10 can prevent the adapter 5 from not rotating into place, causing the straight jet passage 9 and the air passage seat 11 to be misaligned and connected. The annular air passage 10 can solve this problem and prevent the adapter 5 from being tightened in an inconsistent position after being replaced.

[0032] In this embodiment, one side opening of the airway seat 11 is located between a pair of sealing rings 7 . Embodiment 3:

[0033] Reference Figure 1 and Figure 4The difference of this embodiment is that: the jet part includes an air pump connecting seat 12, an air pump 13, an air pump housing 14, a metal contact A15, a metal contact B16, an air pipe 17 and an air transfer pipe 18, the lower surface of the housing 1 is provided with a mounting opening, the air pump connecting seat 12 is embedded in the mounting opening, and the air pump connecting seat 12 is located in the housing 1, the air pump 13 is detachably connected to the air pump housing 14, the top end of the air pump housing 14 is inserted into the air pump connecting seat 12, and the air pump housing 14 is snap-connected to the air pump connecting seat 12, and the air transfer pipe 18 is fixed at On the air pump connecting seat 12, the bottom end of the air transfer tube 18 extends into the air pump connecting seat 12, the top end of the air transfer tube 18 is connected with the airway seat 11 through the air pipe 17, the air pump housing 14 is provided with an air hole, the air outlet end of the air pump 13 is connected with the air hole, the bottom end of the air transfer tube 18 is plugged into the air hole, the lower surface of the air pump connecting seat 12 and the upper surface of the air pump housing 14 are respectively embedded with metal contacts A15 and metal contacts B16, the metal contacts A15 and metal contacts B16 are in contact, and the metal contacts A15 are electrically connected to the control unit 4.

[0034] In actual use: the control unit 4 controls the start and stop of the air pump 13 through the metal contact A15 and the metal contact B16. At the same time, the metal contact A15 and the metal contact B16 can facilitate the disconnection and connection of the air pump housing 14 during disassembly and assembly, thereby reducing the total weight when purging is no longer required, and facilitating replacement and maintenance, thereby achieving modularization.

[0035] The air pump 13 draws in external air and compresses it for discharge. The compressed air is sent into the air transfer tube 18 through the air holes of the air pump housing 14, and then passes through the air pipe 17, the airway seat 11, and the annular airway 10 in sequence, and is discharged from the straight jet channel 9 to achieve the purging operation. Embodiment 4:

[0036] Reference Figure 1 The difference of this embodiment is that: a card plate 19 is formed on the lower surface of the air pump connecting seat 12, and a card slot 1 adapted to the card plate 19 is formed on the outer surface of the air pump housing 14, and the card plate 19 is connected to the card slot 1.

[0037] In actual use: the card plate 19 cooperates with the card slot 1 to facilitate the limiting of the air pump housing 14 to prevent the air transfer tube 18 from not being properly plugged into the air hole. Embodiment 5:

[0038] Reference Figure 1-3The difference of this embodiment is that: the material storage part includes: a driving part, an internal driving part, a silo 20 and a material pipe 21, a slot is opened at the right end of the outer shell 1, the silo 20 is inserted into the slot, the driving part is detachably connected to the outer shell 1, the internal driving part is detachably connected in the silo 20, the driving end of the driving part is connected to the internal driving part, the driving part is electrically connected to the control unit, the silo 20 is connected to the channel seat 8 through the material pipe 21, and a feeding port is opened on the upper surface of the silo 20, and a knob 22 is detachably connected to the feeding port, and the bottom end of the knob 22 is located on the same plane as the inner upper surface of the silo 20.

[0039] The driving part includes a reduction motor 23 and a stirring motor 24, and the reduction motor 23 and the stirring motor 24 can be detachably connected in the outer shell 1, and the driving ends of the reduction motor 23 and the stirring motor 24 are connected to the inner driving part through the slot, and the reduction motor 23 and the stirring motor 24 are electrically connected to the control unit 4.

[0040] The internal drive part includes a rotating shaft 25, a push plate 26, a scraper 27, and a stirring blade 28. The two ends of the rotating shaft 25 are respectively rotatably sealed and connected to the centers of the two ends of the silo 20. One end of the rotating shaft 25 is provided with a plug hole 1, and the driving end of the reduction motor 23 is plugged into the plug hole 1 of the rotating shaft 25. The stirring blade 28 is rotatably sealed and connected to one end of the silo 20, and the stirring blade 28 is located on one side of the rotating shaft 25. One end of the stirring blade 28 is provided with a plug hole 2, and the stirring motor 24 is plugged into the plug hole 2. The push plate 26 is threadedly connected to the rotating shaft 25, and a scraper 27 is fixed on one side of the push plate 26. The scraper 27 has an interference fit with the silo 20, and the outer surface of the push plate 26 has a clearance fit with the inner surface of the silo 20.

[0041] A rubber socket 29 is detachably connected in the slot, one end of which passes through the slot and extends into the housing 1 and communicates with the material pipe 21 . A plug 30 is detachably and hermetically connected to the silo 20 , and the plug 30 is plugged into the rubber socket 29 .

[0042] In actual use: open the feed port through the knob 22, inject the sealant into the silo 20, then reset the knob 22, and start the stirring motor 24 through the control unit 4 at the same time. The stirring motor 24 drives the stirring blade 28 to rotate to stir the sealant in the silo 20. Since the sealant is a fluid, when stirring, it is preferred to place the silo 20 vertically, that is, one end of the nozzle 6 is located at the bottom, which can improve the mixing effect. After stirring for a few minutes, the silo 20 is inverted, that is, one end of the nozzle 6 is located at the top, and then the control unit 4 is used to start the stirring motor 24 ... Element 4 starts the reduction motor 23, which drives the rotating shaft 25 to rotate, and at the same time drives the push plate 26 and the scraper 27 to move, squeezing the sealant in the silo 20. Since the sealant is a fluid, when it is inverted, the air is concentrated at one end of the silo 20, that is, the end with the plug 30, so that the air is discharged through the plug 30, the rubber socket 29, the material tube 21, the channel seat 8, the adapter 5 and the nozzle 6 in sequence. After the air is discharged, the sealant that follows is also discharged in the above order in sequence, and then the spraying operation can continue.

[0043] After use, the reduction motor 23 is operated in reverse to reset the push plate 26 and the scraper 27, and the above steps can be repeated to operate again.

[0044] During cleaning, water or diluted solvent can be repeatedly injected into the feed port, and the push plate 26 and the scraper 27 can be controlled to squeeze the water multiple times to discharge the sealant in the plug 30, the rubber socket 29, the material pipe 21, the channel seat 8, the adapter 5 and the nozzle 6.

[0045] Since the reduction motor 23 and the stirring motor 24 are plugged into the rotating shaft 25 and the stirring blade 28 respectively, and the rubber socket 29 is plugged into the plug 30, the silo 20 can be taken out separately to achieve modularization, thereby facilitating subsequent disassembly, assembly and maintenance.

[0046] The stirring blade 28 is made of elastic metal sheet. When the scraper 27 contacts the stirring blade 28, the stirring blade 28 can deform adaptively to squeeze out more sealant. The scraper 27 returns to its original shape after moving away. At the same time, the stirring end angle of the stirring blade 28 can be changed to improve the mixing efficiency of the sealant.

[0047] At the same time, the start-up time of the reduction motor 23 is used as a basis for judgment. When the scraper 27 is close to the stirring blade 28, the control unit 4 limits the start-up of the stirring motor 24. Embodiment 6:

[0048] Reference Figure 1 The difference of this embodiment is that: the right end of the shell 1 is detachably connected with a second card plate 31, and the lower surface of the silo 20 is provided with a second card slot adapted to the second card plate 31, and the second card plate 31 is engaged with the second card slot after the silo 20 is inserted into the slot.

[0049] In actual use: by connecting the second card plate 31 with the second card slot, the stability of the silo 20 can be improved, and at the same time, the silo 20 can be prevented from being installed in place, resulting in incorrect connection between the reduction motor 23 and the rotating shaft 25, the stirring motor 24 and the stirring blade 28, and the plug 30 and the rubber socket 29. The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Within the knowledge scope of ordinary technicians in the field, various changes can be made without departing from the purpose of the present invention, which are all within the protection scope of this technology.
