Description

Technical Field

[0001] This utility model relates to the field of monitoring devices, and in particular to a boiler water level gauge flushing monitoring device. Background Technology

[0002] A boiler is an energy conversion device. The energy input to the boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. During the operation of the boiler, a water level gauge is needed to measure and control the liquid level in the boiler drum. During long-term use, the water level gauge needs to be cleaned of dirt to ensure its accuracy.

[0003] In existing water level gauges, the cleaning process is usually determined by a combination of manual and mechanical methods. Since the staff cannot visually observe the cleaning process, it is difficult to judge whether the cleaning is thorough. This may result in residues remaining inside the water level gauge, affecting its accuracy. Furthermore, if the cleaning is incomplete or the operation is incorrect, the water level gauge may malfunction, potentially causing accidents such as boiler water shortage or overfilling, resulting in serious consequences for the boiler and the entire system.

[0004] Therefore, in the existing water level gauges, the determination of whether they are clean is usually made manually in conjunction with machinery during flushing. Since the staff cannot directly see the flushing process, it may affect the accuracy of the water level gauge, which may lead to accidents such as boiler water shortage or overfilling. A boiler water level gauge flushing monitoring device can be designed. The monitoring device can automatically monitor the flushing process and ensure that the flushing is carried out smoothly. Utility Model Content

[0005] To overcome the problem that existing water level gauges are usually judged by manual labor and machinery during flushing, which may affect the accuracy of the water level gauge because the staff cannot visually observe the flushing process, and may lead to accidents such as boiler water shortage or overfilling.

[0006] The technical solution of this utility model is as follows: a boiler water level gauge flushing monitoring device, including a water level gauge body, a boiler connecting pipe, a control panel, a flushing force monitoring component, and a flushing cleanliness monitoring component; two sets of boiler connecting pipes connected to the boiler are spaced apart at the outer end of the water level gauge body, and two sets of detection main pipes are respectively provided at the outer end of the two sets of boiler connecting pipes. Detection holes are opened inside the detection main pipes. Two sets of flushing force monitoring components for monitoring the flushing force of the water flow are respectively provided at the ends of the two sets of detection main pipes away from the boiler connecting pipes. The flushing force monitoring component includes a primary fixing seat and a primary detection probe. Two sets of connecting rods are provided between the two sets of flushing force monitoring components. A control panel for controlling the monitoring device is provided at the outer end of the two sets of connecting rods. The two sets of flushing force monitoring components are symmetrically arranged along both ends of the control panel. A flushing cleanliness monitoring component for detecting particles in the flushing water flow is provided at the upper end of the water level gauge body. The flushing cleanliness monitoring component includes a secondary fixing seat, a warning light, and a secondary detection probe.

[0007] Preferably, compared to existing water level gauges where rinsing typically relies on manual labor combined with machinery to determine cleanliness, making it difficult for workers to visually observe the rinsing process and assess its thoroughness, this application combines a rinsing force monitoring component with a rinsing cleanliness monitoring component. During rinsing, the primary detection probe of the rinsing force monitoring component penetrates the detection hole of the main detection pipe and extends into the boiler connecting pipe. As the rinsing water flows past the primary detection probe, it bends under pressure, detecting the rinsing force. This allows for adjustment of the rinsing force based on varying degrees of fouling on the water level gauge. While the rinsing water flows inside the water level gauge, a secondary detection probe extends into the gauge. Fouling particles from the water level gauge detach under the rinsing force and collide with the secondary detection probe. The secondary detection probe detects the frequency of these collisions, indicating the cleanliness of the water level gauge. A warning light of different colors visually displays the rinsing progress to the workers.

[0008] Preferably, there are two sets of primary fixing seats, with a fixing rod between the two sets of primary fixing seats. The two sets of primary fixing seats are fixedly connected by the fixing rod. Each set of primary fixing seats has a connecting seat at the center of one end near the other set of flushing force monitoring components. The center of the connecting seat has a connecting hole, and both ends of the connecting rod extend into the connecting hole. The two sets of flushing force monitoring components are fixedly connected by the connecting rod.

[0009] Preferably, one set of fixing bases has a detection sub-tube at its outer end, the end of the detection sub-tube away from the first-stage fixing base extends into the detection hole, a sealing sleeve is provided between the detection main tube and the detection sub-tube, and a first-stage detection probe is provided at the center of the detection sub-tube.

[0010] Preferably, one set of mounting bases is equipped with a pressure sensor inside, one end of the primary detection probe passes through the primary mounting base and is connected to the pressure sensor, and the other end of the primary detection probe passes through the detection hole and extends into the interior of the boiler connecting pipe.

[0011] Preferably, the outer end of the water level gauge body is provided with a water level scale groove, the upper center of the water level gauge body is provided with a through hole, the secondary fixing seat is located at the upper end of the water level gauge body, the secondary detection probe is located at the lower center of the secondary fixing seat, and the lower end of the secondary detection probe extends through the through hole into the interior of the water level gauge body.

[0012] Preferably, the outer end of the secondary detection probe is fitted with a sealing sleeve corresponding to the through hole, the interior of the secondary fixing seat is equipped with a spring-type displacement sensor, the upper end of the secondary detection probe passes through the secondary fixing seat and is connected to the spring-type displacement sensor, the upper end of the secondary fixing seat is provided with a light groove, the warning light is located inside the light groove, the outer end of the secondary fixing seat is provided with a connecting pipe, one end of the connecting pipe is connected to the secondary fixing seat, and the other end of the connecting pipe is connected to the primary fixing seat of one of the flushing force monitoring components.

[0013] Preferably, the control panel has a display screen at the front end, control buttons below the display screen, two sets of fixing buckles symmetrically arranged at the rear end of the control panel, fixing buckles with fixing slots inside, fixing slots matching and engaging with connecting rods, a battery holder at the center of the rear end of the control panel, a battery pack inside the battery holder, and a spring-type displacement sensor electrically connected to the pressure sensor and control panel.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared to existing water level gauges where cleaning is typically determined manually and mechanically, making it difficult for staff to visually assess the rinsing process and ensure thoroughness, this application combines a rinsing force monitoring component with a rinsing cleanliness monitoring component. During rinsing, the primary detection probe of the rinsing force monitoring component penetrates the detection hole of the main detection pipe and extends into the boiler connecting pipe. As the rinsing water flows past the primary detection probe, it bends under pressure, detecting the rinsing force. This allows for adjustment of the rinsing force based on varying levels of dirt on the water level gauge. While the rinsing water flows inside the water level gauge, a secondary detection probe extends into the gauge. Dirt particles detach from the gauge body under the rinsing force and collide with the secondary detection probe. The secondary detection probe detects the frequency of these collisions, indicating the cleanliness of the water level gauge. Different colored warning lights visually indicate the rinsing progress to the staff. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a boiler water level gauge flushing monitoring device, including a water level gauge body 1, a boiler connecting pipe 2, a control panel 5, a flushing force monitoring component 3, and a flushing cleanliness monitoring component 6. Two sets of boiler connecting pipes 2, connected to the boiler, are spaced apart at the outer end of the water level gauge body 1. Two sets of detection main pipes 9 are respectively provided at the outer ends of the two sets of boiler connecting pipes 2. Detection holes 10 are opened inside the detection main pipes 9. Two sets of flushing force monitoring components 3, monitoring the flushing force of the water flow, are respectively provided at the ends of the two sets of detection main pipes 9 away from the boiler connecting pipes 2. Each flushing force monitoring component 3 includes a primary fixing seat 301 and a primary detection probe 306. Two sets of connecting rods 4 are provided between the two sets of flushing force monitoring components 3. A control panel 5 for controlling the monitoring device is provided at the outer ends of the two sets of connecting rods 4. The two sets of flushing force monitoring components 3 are symmetrically arranged along both ends of the control panel 5. A flushing cleanliness monitoring component 6 for detecting particles in the flushing water flow is provided at the upper end of the water level gauge body 1. The flushing cleanliness monitoring component 6 includes a secondary fixing seat 602, a warning light 604, and a secondary detection probe 606.

[0025] Please see Figures 1-5 In this embodiment, two sets of primary fixing seats 301 are provided, and a fixing rod 304 is provided between the two sets of primary fixing seats 301. The two sets of primary fixing seats 301 are fixedly connected by the fixing rod 304. Each set of primary fixing seats 301 has a connecting seat 302 at the center of one end near the other set of flushing force monitoring components 3. A connecting hole 303 is opened in the center of the connecting seat 302. Both ends of the connecting rod 4 extend into the interior of the connecting hole 303. The two sets of flushing force monitoring components 3 are fixedly connected by the connecting rod 4. The combination of the connecting seat 302 and the connecting hole 303 allows the operator to connect the connecting rod 4 during installation. The two ends of the device are inserted into the connection holes 303 of the two sets of flushing force monitoring components 3, thereby connecting the two sets of flushing force monitoring components 3 together. One set of fixed bases has a detection sub-tube 305 at its outer end. The end of the detection sub-tube 305 away from the first-level fixed base 301 extends into the detection hole 10. A sealing sleeve is provided between the detection mother tube 9 and the detection sub-tube 305. The center of the detection sub-tube 305 is provided with a first-level detection probe 306. By combining the detection sub-tube 305 with the detection mother tube 9, the two sets of flushing force monitoring components 3 can insert their respective first-level detection probes 306 into the boiler connecting pipe 2 to detect the water flow impact force.

[0026] Please see Figures 3-5In this embodiment, a pressure sensor (model PR6212 / 1T) is installed inside one of the fixing bases. C1), one end of the primary detection probe 306 passes through the primary fixing seat 301 and is connected to the pressure sensor. The other end of the primary detection probe 306 passes through the detection hole 10 and extends into the interior of the boiler connecting pipe 2. By combining the primary detection probe 306 with the pressure sensor, the primary detection probe 306 is bent under pressure when the water flows through it. The pressure sensor senses the bending degree of the primary detection probe 306 under pressure, thereby detecting the flushing force of the flushing water flow. A water level scale groove 7 is opened at the outer end of the water level gauge body 1. A through hole 8 is opened at the center of the upper end of the water level gauge body 1. The secondary fixing seat 602 is located at the upper end of the water level gauge body 1. The secondary detection probe 606 is located at the center of the lower end of the secondary fixing seat 602. The lower end of the secondary detection probe 606 passes through the through hole 8 and extends into the interior of the water level gauge body 1. By combining the secondary detection probe 606 with the through hole 8, the secondary detection probe 606 can pass through the through hole 8 and extend into the interior of the water level gauge body 1, thereby detecting the flushing cleanliness inside the water level gauge body 1.

[0027] Please see Figures 3-6In this embodiment, the outer end of the secondary detection probe 606 is fitted with a sealing sleeve 605 corresponding to the through hole 8. A spring-type displacement sensor (model GCA-121-050) is installed inside the secondary mounting base 602. The upper end of the secondary detection probe 606 passes through the secondary mounting base 602 and connects to the spring-type displacement sensor. A light groove 603 is provided at the upper end of the secondary mounting base 602, and a warning light 604 is located inside the light groove 603. A connecting pipe 601 is provided at the outer end of the secondary mounting base 602. One end of the connecting pipe 601 is connected to the secondary mounting base 602, and the other end of the connecting pipe 601 is connected to the primary mounting base 301 of one of the flushing force monitoring components 3. Through the combination of the secondary detection probe 606 and the spring-type displacement sensor, when the water flows, the dirt particles on the water level gauge body 1 are dislodged from the water level gauge body 1 under the flushing force of the water flow, and thus collide with the water flow. The secondary detection probe 606 detects the frequency of dirt particle collisions and detects the cleanliness of the water level gauge body 1. The warning light 604 emits different colored lights to visually display the rinsing progress to the staff. The control panel 5 has a display screen 11 at the front end and a control button 12 below the display screen 11. The control panel 5 has two sets of fixing buckles 13 symmetrically arranged at the rear end. The fixing buckles 13 have fixing slots 14 inside, which match and engage with the connecting rod 4. The battery holder 15 is located at the center of the rear end of the control panel 5. The battery holder 15 contains a battery pack 16. The spring displacement sensor and pressure sensor are electrically connected to the control panel 5. Through the combination of the display screen 11 and the control button 12, the staff can visually see the rinsing data on the display screen 11 and adjust the sensitivity of the rinsing monitoring by pressing the control button 12.

[0028] During operation, the operator can insert both ends of the connecting rod 4 into the connecting holes 303 of the two sets of flushing force monitoring components 3, thereby connecting the two sets of flushing force monitoring components 3 together. By combining the detection sub-tube 305 with the detection mother tube 9, the two sets of flushing force monitoring components 3 can insert their respective primary detection probes 306 into the boiler connecting pipe 2 to detect the water flow impact force. When the water flow passes through the primary detection probe 306, the primary detection probe 306 is bent by pressure. The pressure sensor senses the bending degree of the primary detection probe 306 under pressure, thereby detecting the flushing force of the flushing water flow.

[0029] The secondary detection probe 606 can pass through the through hole 8 and extend into the interior of the water level gauge body 1 to detect the cleanliness of the water level gauge body 1. When the water flows, the dirt particles of the water level gauge body 1 are detached from the water level gauge body 1 under the flushing of the water flow, and collide with the secondary detection probe 606 under the drive of the water flow. The secondary detection probe 606 detects the degree of cleanliness of the water level gauge body 1 by sensing the frequency of the dirt particle collision, and the warning light 604 emits different colored warning lights to intuitively show the flushing progress to the staff.

[0030] Through the above steps, by combining the flushing force monitoring component 3 and the flushing cleanliness monitoring component 6, when flushing the water level gauge body 1, the detection end of the primary detection probe 306 of the flushing force monitoring component 3 can pass through the detection hole 10 of the detection header 9 and penetrate into the interior of the boiler connecting pipe 2. When the flushing water flows through the primary detection probe 306, the primary detection probe 306 is bent by pressure, thereby detecting the flushing force of the flushing water flow. This allows for adjustment of the flushing force according to different levels of dirt on the water level gauge. When the flushing water flows inside the water level gauge body 1, the secondary detection probe 606 extends into the interior of the water level gauge. Dirt particles on the main body 1 are detached from the water level gauge body 1 under the flushing of water flow, and then collide with the secondary detection probe 606 under the influence of the water flow. The secondary detection probe 606 detects the frequency of the dirt particle collisions and detects the cleanliness of the water level gauge body 1. The flushing progress is then visually displayed to the staff by emitting different colored warning lights 604. This solves the problem that in the current water level gauge, the flushing process is usually judged by manual labor and machinery. Since the staff cannot visually see the flushing process, it may affect the accuracy of the water level gauge, which may lead to accidents such as boiler water shortage or overfilling.
