Description

Technical Field

[0001] This utility model relates to the field of hammer sensor technology, and in particular to a hammer sensor prism cleaning device. Background Technology

[0002] In industrial sugar production, syrup concentration is achieved through continuous evaporation. To facilitate monitoring of the syrup concentration process, a prism sensor is often used to detect the syrup prism saturation. However, the prism of the prism sensor is prone to accumulating dirt during use, affecting the accuracy of the detection. For example, Chinese Patent Application No. 201510127291.5 discloses an online automatic measurement and control system for syrup saturation saturation, which uses water to rinse the prism and clean it periodically. However, the rinsing water enters the syrup and needs to be evaporated, increasing energy consumption. To address this, a prism inspection surface cleaning device for sugar mill syrup saturation sensors, as disclosed in Chinese Patent Application No. 201821717425.4, has been developed. This device uses a motor-driven transmission shaft to drive a wire brush to clean the prism inspection surface, eliminating the need for water rinsing and reducing subsequent evaporation energy consumption. However, the application only uses a sealing union for sealing. In actual use, syrup is under pressure, and leakage will still occur after long-term use. Because the location is inside the pipe, leakage is not easy to detect. Leaked syrup can easily enter the motor, causing the motor to short-circuit and burn out. Using this solution requires regular inspection or waterproof modification of the motor, which increases the difficulty of later maintenance. Therefore, a hammer sensor prism cleaning device is needed, which is driven by a magnetic coupling. When syrup leaks, it can prevent syrup from entering the motor and reduce the difficulty of later maintenance. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a cleaning device for a hammer sensor prism, which uses a magnetic coupling for transmission. This prevents sugar syrup from entering the motor during leakage, reducing the difficulty of subsequent maintenance.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a cleaning device for a hammer sensor prism, comprising: a hammer sensor body, a connecting pipe, a planetary gear reducer, a first transmission rod, a second transmission rod, a magnetic coupling, and a motor. The hammer sensor body has an opening on one side, and one end of the connecting pipe is connected to the opening of the hammer sensor body via a flange. The planetary gear reducer is installed in the connecting pipe. The input end of the planetary gear reducer is connected to the first transmission rod, and the output end of the planetary gear reducer is connected to the second transmission rod. One end of the second transmission rod passes through the connecting pipe and extends above the prism of the hammer sensor body, and a wire brush is provided at the end of the second transmission rod. A first cap is provided at the end of the connecting pipe, and the motor is coaxially mounted on one side of the connecting pipe through the first cap. The output shaft of the motor is connected to the first transmission rod via a magnetic coupling.

[0006] Furthermore, the magnetic coupling includes a first transmission plate and a second transmission plate, which are respectively mounted on the output shaft of the motor and the first transmission rod, and permanent magnet blocks are evenly mounted on the first transmission plate and the second transmission plate.

[0007] Furthermore, the first cap is made of plastic.

[0008] Furthermore, a connecting plate is provided on one side of the first cover, the motor is connected to the first cover through the connecting plate, and the lower part of the motor is also connected to the ground through a support frame.

[0009] Furthermore, a partition is provided inside the connecting pipe, and the partition is connected to the second transmission rod through a sealed bearing.

[0010] Furthermore, the connecting pipe has a detection port on the lower part of one side of the partition, and the detection port is provided with a second cap.

[0011] Furthermore, the planetary gear reducer includes a gear ring, planetary gears, a sun gear, and a housing. The gear ring and the housing are fixedly installed inside a connecting pipe. The sun gear is coaxially installed in the middle of the gear ring. The planetary gears are installed between the sun gear and the gear ring, and the planetary gears are connected to each other through a planet carrier. The housing covers both sides of the gear ring.

[0012] Furthermore, the first transmission rod is connected to the sun gear, and the second transmission rod is connected to the planet carrier.

[0013] The beneficial effects of this utility model are as follows: By setting a connecting pipe on one side of the hammer sensor body and a first cover on the other side of the connecting pipe, and enabling the motor to achieve air transmission through a magnetic coupling, the problem of syrup leakage damaging the motor when the sealed bearing fails can be effectively avoided. Furthermore, the first transmission rod is connected to the second transmission rod through a planetary gear reducer, which can amplify the torque so that the second transmission rod can obtain sufficient torque to drive the wire brush to wipe the prism of the hammer sensor body, keeping the prism clean and ensuring the accuracy of hammer detection.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0024] like Figures 1 to 6 As shown, an embodiment of this utility model provides a hammer sensor prism cleaning device, including: a hammer sensor body 1, a connecting pipe 2, a planetary gear reducer 3, a first transmission rod 4, a second transmission rod 5, a magnetic coupling 6, and a motor 7. The hammer sensor body 1 has an opening on one side. One end of the connecting pipe 2 is connected to the opening of the hammer sensor body 1 through a flange. The planetary gear reducer 3 is installed in the connecting pipe 2. The input end of the planetary gear reducer 3 is connected to the first transmission rod 4, and the output end of the planetary gear reducer 3 is connected to the second transmission rod 5. One end of the second transmission rod 5 passes through the connecting pipe 2 and extends to the top of the prism of the hammer sensor body 1. A wire brush 8 is provided at the end of the second transmission rod 5. A first cover 9 is provided at the end of the connecting pipe 2. The motor 7 is coaxially installed on one side of the connecting pipe 2 through the first cover 9. The output shaft of the motor 7 is connected to the first transmission rod 4 through the magnetic coupling 6.

[0025] When the prism of the hammer sensor body 1 needs cleaning, the motor 7 is started. The motor 7 drives the first transmission plate 10 to rotate, and under the action of magnetism, the second transmission plate 11 rotates along with the first transmission plate 10. The magnetism can pass through the first plastic cover 9, achieving air-to-ground transmission. After the second transmission plate 11 rotates, it drives the first transmission rod 4 to rotate, and through the planetary gear reducer 3, it drives the second transmission rod 5. Figure 2 As shown, after the second transmission rod 5 rotates, it will drive the wire brush 8 at its end to wipe the prism of the hammer sensor body 1 to prevent scale buildup. The hardness of the prism is higher than that of the wire brush 8, so the wire brush 8 will not scratch the prism when cleaning the scale, thus ensuring the normal operation of the prism.

[0026] Since the magnetic coupling 6 transmits power through magnetic force, its maximum torque is relatively low. In order to ensure that the second transmission rod 5 has sufficient torque to overcome the resistance and drive the wire brush 8, this device uses a planetary gear reducer 3 to amplify the torque. By setting the gear ratio of the sun gear 20 and the planetary gear 19, the torque can be amplified by 2 to 3 times, so that the second transmission rod 5 can rotate smoothly.

[0027] Since the connecting pipe 2 is sealed by the first cap 9, when the sealing bearing 16 fails, the leaked syrup will be blocked in the connecting pipe 2 by the first cap 9, preventing the syrup from entering the motor 7, preventing damage, and ensuring the reliability of the equipment.

[0028] Specifically, such as Figure 5 As shown, the magnetic coupling 6 includes a first transmission plate 10 and a second transmission plate 11. The first transmission plate 10 and the second transmission plate 11 are respectively mounted on the output shaft of the motor 7 and the first transmission rod 4. Permanent magnet blocks 12 are evenly installed on the first transmission plate 10 and the second transmission plate 11. The permanent magnet blocks 12 at corresponding positions on the first transmission plate 10 and the second transmission plate 11 have opposite magnetic poles, so that the first transmission plate 10 can be driven by the motor 7, and the first transmission plate 10 and the second transmission plate 11 can rotate synchronously through the combined action of opposite poles attracting and like poles repelling. The magnetic force realizes the transmission without contact, ensuring that the inside of the connecting pipe 2 is in a closed state, and the motor 7 will not be damaged when the sugar juice leaks.

[0029] Preferably, the first cover 9 is made of plastic. The plastic material of the first cover 9 facilitates the passage of magnetic force, ensuring the efficient transmission of the magnetic coupling 6.

[0030] Specifically, a connecting plate 13 is provided on one side of the first cover 9. The motor 7 is connected to the first cover 9 through the connecting plate 13, and the lower part of the motor 7 is also connected to the ground through the support frame 14. The motor 7 is positioned by the connecting plate 13, so that after the motor 7 is installed, the centers of the first transmission plate 10 and the second transmission plate 11 can be on the same axis, thereby improving the smoothness of transmission.

[0031] Specifically, such as Figure 4 As shown, a partition 15 is provided inside the connecting pipe 2. The partition 15 is connected to the second transmission rod 5 through a sealed bearing 16. The sealed bearing 16 is a commercially available sealed bearing 16, which is used to form the first barrier to prevent the sugar juice from seeping into the connecting pipe 2 and to ensure the normal operation of the device.

[0032] In one specific embodiment, the connecting pipe 2 has a detection port on the lower part of one side of the partition 15, and a second cover 17 is provided on the detection port. Maintenance personnel can periodically open the second cover 17. If the sealing bearing 16 fails, the sugar juice seeps into the connecting pipe 2 and concentrates at the lower part of the connecting pipe 2. If sugar juice flows out after opening the second cover 17, it indicates that the sealing bearing 16 has failed and needs to be replaced. The second cover 17 is easy to open, reducing the difficulty of inspection.

[0033] In a specific embodiment, such as Figure 6 As shown, the planetary gear reducer 3 includes a gear ring 18, planetary gears 19, a sun gear 20, and a housing 21. The gear ring 18 and the housing 21 are fixedly installed inside the connecting pipe 2. The sun gear 20 is coaxially installed in the middle of the gear ring 18. The planetary gears 19 are installed between the sun gear 20 and the gear ring 18, and the planetary gears 19 are connected by a planet carrier 22. The housing 21 covers both sides of the gear ring 18. Planetary gear reducers are widely used in fields such as electric drills. The reduction principle of the planetary gear reducer 3 in this device is the same as that of existing planetary gear reducers. When the sun gear 20 rotates, it drives the planetary gears 19 to rotate, thereby driving the planet carrier 22 to rotate, realizing the amplification of torque, so that the second transmission rod 5 obtains sufficient torque, overcoming the problem of low torque transmission of the magnetic coupling 6.

[0034] In a preferred embodiment, the first transmission rod 4 is connected to the sun gear 20, and the second transmission rod 5 is connected to the planetary carrier 22, so that the torque of the first transmission rod 4 is amplified by the planetary gear reducer 3 and transmitted to the second transmission rod 5, ensuring that the second transmission rod 5 has sufficient torque to drive the wire brush 8 to clean the prism of the hammer sensor body 1.

[0035] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
