Description

Technical Field

[0001] The utility model relates to an intelligent capacitance water level gauge for detecting a boiler steam drum, and in particular to an intelligent capacitance water level gauge for detecting a boiler steam drum applied in the field of capacitance water level gauges. Background Art

[0002] During the startup process of the drum boiler, the drum, water-cooled wall, economizer, superheater, reheater and other equipment are protected. The capacitance level gauge is a commonly used tool on the boiler. The capacitance level gauge is a commonly used liquid level detection device. It can measure the capacitance value between the two electrodes above and below the liquid level to achieve fast and accurate measurement of the liquid level.

[0003] When using the existing intelligent capacitance water level gauge for boiler drum detection, personnel usually wrap a protective film on the outer end of the display to protect the display. When external force acts on the protective film, not only will the protective film be damaged, but the effect of the protective film in isolating the external force is less than ideal. Therefore, a larger part of the external force will act on the display, and the effect of protecting the display on the capacitance water level gauge is less than ideal. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that it is inconvenient for personnel to protect the display on the intelligent capacitance water level gauge used for boiler drum detection.

[0005] To solve the above problems, the utility model provides an intelligent capacitance water level gauge for boiler drum detection, including a water level gauge body, a round seat fixedly connected to the water level gauge body, a display fixedly connected to the upper end of the round seat, a round groove opened at the upper end of the round seat, a protective cover inserted into the circular groove, the protective cover sleeved on the outside of the display, a transparent block fixedly connected to the upper end of the protective cover, a supporting block fixedly connected to the outer end of the protective cover, a fixed block fixedly connected to the upper end of the supporting block, a moving tube rotatably sleeved on the outer end of the fixed block, a cross bar fixedly connected to the outer end of the moving tube, a round block fixedly connected to the end of the cross bar away from the moving tube, and a sponge block fixedly connected to the lower end of the round block.

[0006] In the above-mentioned intelligent capacitance water level gauge for boiler drum detection, a protective cover is used to isolate the external force from the display of the water level gauge body, thereby preventing the external force from directly acting on the display.

[0007] As a further improvement of the present application, a sealing cover is provided on the outer end of the round block, and the lower end of the sponge block and the upper end of the transparent block are both on the same horizontal plane.

[0008] As a further improvement of the present application, the outer end of the round block is coated with a magnetic coating 1, and the inner wall of the sealing cover is coated with a magnetic coating 2.

[0009] As another improvement of the present application, a pair of limit grooves are provided at the upper end of the round seat, and the limit grooves are internally slidably connected to limit blocks. The ends of the limit blocks close to each other are fixedly connected to a pair of tension springs and limit rods, and the ends of the tension springs away from the limit blocks are fixedly connected to the inner wall of the limit groove. A circular hole is provided on the inner wall of the limit groove, and a pair of reinforcement grooves are provided at the outer end of the protective cover.

[0010] As another improved supplement of the present application, one end of the limiting rod away from the limiting block passes through the circular hole and is inserted into the interior of the reinforcement groove.

[0011] As another improved supplement of the present application, in the initial state, the tension spring is in an extended state, and one end of the limit block away from the limit rod is fixedly connected to a handle.

[0012] In summary, the water level gauge utilizes a protective cover to isolate the external force from the display of the water level gauge body, thereby preventing the external force from directly acting on the display, thereby increasing the service life of the display.

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1-6 The invention discloses an intelligent capacitance water level gauge for detecting a boiler drum, comprising a water level gauge body 1, a round seat 2 being fixedly connected to the water level gauge body 1, a display being fixedly connected to the upper end of the round seat 2, a round groove 3 being opened at the upper end of the round seat 2, a protective cover 4 being inserted in the inner part of the round groove 3, the protective cover 4 being sleeved on the outer side of the display, a transparent block 5 being fixedly connected to the upper end of the protective cover 4, a supporting block 6 being fixedly connected to the outer end of the protective cover 4, a fixed block 7 being fixedly connected to the upper end of the supporting block 6, a moving pipe 8 being rotatably sleeved on the outer end of the fixed block 7, a cross bar 9 being fixedly connected to the outer end of the moving pipe 8, a round block 10 being fixedly connected to the end of the cross bar 9 away from the moving pipe 8, a sponge block 11 being fixedly connected to the lower end of the round block 10, a sealing cover 12 being sleeved on the outer end of the round block 10, the lower end of the sponge block 11 and the upper end of the transparent block 5 being both on the same horizontal plane, the outer end of the round block 10 being coated with a magnetic coating 13, and the inner wall of the sealing cover 12 being coated with a magnetic coating 2 14.

[0024] When in use, the protective cover 4 is sleeved on the display of the water level gauge body 1, and the lower end of the protective cover 4 is inserted into the circular groove 3, so that the protective cover 4 is installed on the round seat 2, and the display of the water level gauge body 1 is protected by the protective cover 4. When an external force moves toward the display, the protective cover 4 is used to isolate the external force from the display of the water level gauge body 1, thereby preventing the external force from directly acting on the display, thereby increasing the service life of the display. When the protective cover 4 is used to protect the display, the transparent block 5 is used to facilitate personnel to observe the indication on the display through the protective cover 4;

[0025] When foreign matter and dust adhere to the transparent block 5, the sealing cover 12 needs to be removed from the round block 10 to separate the magnetic coating 1 13 from the magnetic coating 2 14. After removing the sealing cover 12, the round block 10 is turned toward the transparent block 5. At the same time, the round block 10 will drive the cross bar 9 and the sponge block 11 to rotate together, and the moving tube 8 will rotate on the fixed block 7. When the sponge block 11 is moved onto the transparent block 5, the upper end of the transparent block 5 will contact the lower end of the sponge block 11. The sponge block 11 is continued to be rotated to make it slide on the transparent block 5. The dust and foreign matter adhered to the transparent block 5 can be wiped off with the sponge block 11, so that it is convenient for personnel to clean the transparent block 5 and reduce the impact of foreign matter and dust adhering to the transparent block 5 on personnel when they pass through the transparent block 5 to view the indication on the display.

[0026] The second implementation method:

[0027] Based on the first embodiment, this embodiment adds structures such as a tension spring 17 and a limit rod 18, and the rest of the parts are consistent with the first embodiment.

[0028] Figure 2 and Figure 4 as well as Figure 6 It is shown that a pair of limit grooves 15 are opened at the upper end of the round seat 2, and the limit grooves 15 are internally slidably connected to the limit blocks 16. The ends of the pair of limit blocks 16 close to each other are fixedly connected to a pair of tension springs 17 and limit rods 18. The end of the tension spring 17 away from the limit block 16 is fixedly connected to the inner wall of the limit groove 15. A circular hole 19 is opened on the inner wall of the limit groove 15. A pair of reinforcement grooves 20 are opened at the outer end of the protective cover 4. The end of the limit rod 18 away from the limit block 16 passes through the circular hole 19 and is inserted into the interior of the reinforcement groove 20. In the initial state, the tension spring 17 is in an extended state, and the end of the limit block 16 away from the limit rod 18 is fixedly connected to a handle.

[0029] When installing the protective cover 4, it is necessary to manually pull the limit block 16 so that it pulls the limit rod 18 and the tension spring 17 to move to the side away from the round seat 2, so that the tension spring 17 is stretched. After the lower end of the protective cover 4 is inserted into the circular groove 3, the external force on the limit block 16 is removed, so that the tension spring 17 drives the limit block 16 to move to the side close to the round seat 2. At the same time, the limit rod 18 will move with the limit block 16, and then one end of the limit rod 18 will pass through the circular hole 19 and be inserted into the reinforcement groove 20 on the protective cover 4, thereby limiting the protective cover 4 and fixing it on the round seat 2. When disassembling, it is only necessary to pull one end of the limit rod 18 out of the reinforcement groove 20, manually move the protective cover 4 up, and remove it from the round seat 2, so as to facilitate personnel to disassemble and install the protective cover 4.

[0030] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
