Description

Technical Field

[0001] The invention relates to a self-cleaning device for underwater equipment, and in particular to an automatic algae removal device with an underwater LED lamp having a spray head. Background Art

[0002] In order to create a better viewing effect, many landscape scenes are not only equipped with fountains, but also with underwater LED lights. With the continuous development of technology, underwater LED lights with nozzles are born; and the problems that arise are also increasing. For example, too much algae garbage is generated on the LED lamp surface, which seriously affects the lighting effect and is very inconvenient to clean. Conventional rags, sponges and other tools cannot be effectively cleaned, and algae are prone to repeated growth. At the same time, ordinary brushes cannot effectively remove algae garbage on the LED lamp surface. Usually, only scrapers can be used to effectively remove them. Underwater LED lights with nozzles are placed in pools, rivers, cave streams and other locations for a long time. The cleaning environment is relatively complex and very inconvenient for manual cleaning. Therefore, some inventors have proposed to set a scraper on the LED lamp surface, but the drive mode is very difficult to set and the scraper cannot be effectively driven to operate. In addition, because it is operated underwater, the sealing requirements are high, and conventional electrical equipment cannot be directly installed; secondly, even if the scraper can be driven, the cleaned algae garbage will fall on the LED lamp surface again without water flow guidance, which greatly reduces the effect achieved.

[0026] The principle of the automatic algae removal device with underwater LED lamp with nozzle of the present invention is as follows: when the underwater LED lamp with nozzle opens the fountain water pipeline, the nozzle 2-2 sprays water, and the fountain water in the nozzle connecting pipe 2-3 introduces part of the water into the driving chamber 3-8 through the driving nozzle 3-1, and the driving nozzle 3-1 is opened and closed by the water outlet electric control valve 3-2. When the water outlet electric control valve 3-2 is in the open state, the driving nozzle 3-1 impacts the impact blade 3-3, and the impact blade 3-3 is driven by the force to drive the wheel arm 3-4 to rotate. Since the wheel arm 3-4 is connected to the driving output gear 3-5, the driving output gear 3-5 is driven to rotate. The output gear 3-5 drives the transmission input gear 4-1 to rotate, and the transmission input gear 4-1 introduces power into the reducer 4-2 through the first transmission shaft 4-3. After the reducer 4-2 adjusts the speed, it transmits the power through the intermediate input gear 4-5. The intermediate input gear 4-5 transmits the power to the intermediate output gear 4-4. The intermediate output gear 4-4 transmits the power to the transmission output gear 4-7 through the second transmission shaft 4-6. The transmission output gear 4-7 drives the scraper frame 5-1 to rotate, thereby, the scraper 5-2 set on the scraper frame 5-1 effectively cleans the LED lamp surface 1-2. When the water outlet electric control valve 3-2 is in the closed state, the nozzle 2-2 continues to spray water, and the algae removal device is suspended.

[0027] The underwater LED lamp automatic algae removal device with a nozzle of the present invention is provided with a reducer 4-2, which can effectively avoid large power fluctuations of the driving unit 3. Most of the current fountain heads use constantly changing water pressure to form a better viewing experience for visual effects, especially the current musical fountains. When the water pressure changes to a relatively high level, its impact force will seriously damage the structural parts of the transmission unit 4 and the algae scraping unit 5. Therefore, the reducer 4-2 is used to effectively prevent the impact on the structural parts when the driving force is high, and at the same time, it also provides a stable and appropriate power input for the algae scraping unit 5.

[0028] The automatic algae removal device of the underwater LED lamp with a nozzle of the present invention adopts a two-stage shaft transmission. The first transmission shaft 4-3 is mainly used for centralized adjustment and is arranged as a whole below the LED lamp body 1, and will not increase the radial width of the LED lamp body 1; the second transmission shaft 4-6 transmits the adjusted power to the top of the LED lamp body 1, and only the second transmission shaft 4-6 increases the radial width of the LED lamp body 1 by a very small part. According to this design, the structure is more compact, the functional area setting is more reasonable, the overall installation of the LED lamp body 1 is more convenient, and the aperture of the mounting hole of the LED lamp body 1 will not be greatly increased due to the arrangement of the automatic algae scraping device. In particular, the transmission is more stable and reliable.

[0029] The automatic algae removal device with underwater LED lights and nozzles of the present invention adopts a dry-wet separation shell structure. The drive unit shell 3-6 is an independent shell structure. All joints adopt a waterproof sealing structure to effectively prevent water overflow in the drive unit 3 from affecting the structural operation of the transmission unit 4. The transmission adjustment shell 4-8 and the transmission output shell 4-9 both adopt an independent shell structure, which is convenient for disassembly, maintenance, and installation.

[0030] The driving unit shell 3-6 of the underwater LED lamp automatic algae removal device with a nozzle of the present invention is connected to the drain pipe 3-7. The drain port is not directly designed, but the water in the driving cavity is returned to the through-hole sleeve 1-9 through the drain pipe 3-7, and the water discharged into the through-hole sleeve 1-9 is discharged along the upper end of the through-hole sleeve 1-9. Since the nozzle 2-2 is installed at the center position of the through-hole sleeve 1-9, the high-pressure water sprayed by the nozzle 2-2 will discharge the water flowing into the through-hole sleeve 1-9 from the drain pipe 3-7 to the surroundings at the upper end of the through-hole sleeve 1-9, which can be directly used to flush the dirt scraped by the algae scraping unit, and can quickly discharge the dirt, forming an effective cooperation with the algae scraping unit; if this drainage method is not used, the nozzle 2-2 will spray high pressure When water is sprayed, a large negative pressure will be formed around the water outlet of the nozzle 2-2, causing the dirt scraped out by the algae scraping unit 5 to be adsorbed by the negative pressure to the vicinity of the water outlet of the nozzle 2-2, so that a large amount of dirt is deposited in the through-hole sleeve 1-9 and cannot be cleaned, resulting in the growth of more algae dirt. Therefore, the underwater LED light automatic algae removal device with a nozzle of the present invention connects the drainage of the driving cavity to the through-hole sleeve 1-9, that is, the nozzle through-hole, through the drain pipe 3-7, effectively cooperating with the algae scraping unit 5 to clean the dirt, and at the same time, compensating for the negative pressure caused by the nozzle 2-2 during the water spraying process, and will not accumulate too much algae dirt in the through-hole sleeve 1-9, forming a better sewage discharge direction in the algae removal process, and solving the problem of only scraping algae without clearing dirt.

[0031] like Figures 1 to 7As shown, the rotation coverage area of ​​the scraper 5-2 is equal to the area of ​​the LED lamp surface 1-2. This design is mainly for effectively and comprehensively cleaning the algae dirt on the LED lamp surface 1-2. The scraper 5-2 is one or more than one piece, all of which are installed between the double rings of the scraper frame 5-1. The scraper 5-2 of this design is supported by the two ends of the double rings of the scraper frame 5-1, which effectively ensures that the force of the scraper 5-2 is balanced when working, so that the blade of the scraper 5-2 can better contact the LED lamp surface 1-2, and there will be no gap between the blade of the scraper 5-2 and the LED lamp surface 1-2, which seriously affects the cleaning effect of the scraper 5-2. When the present invention is provided with multiple scrapers 5-2, they can compensate for each scraper 5-2 due to the incomplete balance of force. Dead corners caused by cleaning, that is, if one of the scrapers 5-2 has a dead corner, the other scraper 5-2 can supplement the cleaning to form an overall complete cleaning effect. A spring clamping structure 6 is arranged between the upper side of the outer ring 5-1-1 of the scraper frame and the transmission output housing 4-9. The spring clamping structure 6 includes a spring 6-1, a clamping wheel seat 6-2 and a clamping wheel 6-3. One end of the spring 6-1 is connected to the transmission output housing 4-9, and the other end is connected to the clamping wheel seat 6-2. The clamping wheel 6-3 is pivoted to the clamping wheel seat 6-2 and contacts the top surface of the scraper frame 5-1. The spring clamping structure is one or more groups, which are evenly spaced on the upper side of the outer ring 5-1-1 of the scraper frame. This design can better maintain the smoothness of the operation of the scraper frame 5-1 and increase the cleaning effect of the scraper frame 5-1, even if the scraper 5-2 has a force acting on the LED lamp surface 1-2. At the same time, the upper and lower positions of the scraper frame 5-1 at the opening of the transmission output housing 4-9 are provided with dynamic sealing structures. Since the LED lamp surface 1-2 is a fixed end, the transmission output housing 4-9 is installed on this fixed end. Therefore, the dynamic sealing structure on the scraper frame 5-1 is easily compressed and damaged, and the spring compression structure 6 effectively alleviates this problem. The drive output gear housing 3-9 is provided on the outside of the drive output gear 3-5, and the drive output gear housing 3-9 is provided with an opening to communicate with the chamber of the transmission adjustment housing 4-8. In order to further ensure the waterproof effect of the transmission unit 4, it is designed in this way. The drive nozzle 3-1 is one or more, and multiple drive nozzles 3-1 are evenly spaced. In order to achieve a better driving effect, a multi-nozzle interval setting structure is adopted. A scraper seat 5-3 is also provided between the double rings of the scraper frame 5-1, and a scraper 5-2 is installed on the scraper seat 5-3, and the scraper 5-2 is set to 3 to 4 pieces. In order to further enhance the stability of the scraper 5-2 during operation, a scraper seat 5-3 is provided, and the scraper seat 5-3 provides a more stable support effect for the scraper 5-2. The scraper seat 5-3 is also provided with an auxiliary blade 5-4, which is arranged perpendicular to the scraper 5-2. The blade seat of the auxiliary blade 5-4 is installed on the scraper seat 5-3, and its blade faces outward. Since the scraper frame 5-1 is provided in the present invention, some dirt is easily stuck. The auxiliary blade 5-4 can cut off the stuck dirt, effectively avoiding the dirt stuck in the scraper frame 5-1.There is one or more drain pipes 3-7, one end of each drain pipe 3-7 is evenly distributed along the driving unit 3 and connected to the driving cavity, and the other end is evenly distributed along the nozzle mounting seat 2-1 and connected to the through-hole sleeve 1-9. The distribution of multiple drain pipes 3-7 can make drainage more stable and the driving unit 3 run more smoothly. The water outlet electric control valve 3-2 can be replaced with a time-delay relay control valve and is electrically connected to the main control circuit board 1-6. The water outlet electric control valve 3-2 requires manual operation of the main control circuit board 1-6. Specifically, the main control circuit board 1-6 is electrically connected to the shore controller, and the shore controller controls the main control circuit board 1-6. The main control circuit board 1-6 controls the opening and closing of the valve body. Replacing it with a delay relay control valve can automatically control the opening and closing of the valve body by setting a fixed time interval, so that the degree of automation of the present invention is better. It can be understood that both the water outlet electric control valve 3-2 and the delay relay control valve are electrically connected to the main control circuit board 1-6, and are controlled by the main control circuit board 1-6. The electrical connection can enter the LED lamp body 1 through the cable waterproof installation head 1-8, which will not increase the difficulty of waterproof sealing of the LED lamp body 1. Of course, the connection lines of the water outlet electric control valve 3-2 or the delay relay control valve extending out of the drive unit 3 need to be waterproof sealed.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
