When the staff is not on site and the water level is too high, the excessively high water level will cause water to enter the water measuring pipe from the drainage pipe and into the glass connecting pipe, causing overall damage. There are certain limitations. Summary of the invention

[0005] The utility model provides a boiler water level monitoring device, aiming to solve the problems that when the monitor is in use, the staff needs to be beside the boiler all the time, which increases the working intensity of the staff, and the degree of automation needs to be improved. When the staff is not on site and the water level is too high, the excessive water level will cause water to enter the measuring water pipe from the drainage pipe and then enter the glass connecting pipe, which will cause damage to the whole, and there are certain limitations.

[0006] An embodiment of the utility model provides a boiler water level monitoring device, which includes a base, a boiler is installed on the base, a water inlet pipe is connected to the top of the boiler, the water inlet pipe is controlled by a first solenoid valve, a water outlet pipe is connected to the side wall of the boiler, the water outlet pipe is controlled by a second solenoid valve, a water level monitoring mechanism is installed on the surface of the boiler, a remote monitoring mechanism is arranged directly in front of the water level monitoring mechanism, and a control component installed on the boiler is also included. The control component can control the first solenoid valve, the second solenoid valve, the water level monitoring mechanism and the remote monitoring mechanism to work normally, and the control component is electrically connected to the first solenoid valve, the second solenoid valve, the water level monitoring mechanism and the remote monitoring mechanism.

[0007] Further, the water level monitoring mechanism includes a two-color water level gauge and a float water level gauge installed on the surface of the boiler. Both the two-color water level gauge and the float water level gauge are connected to the inside of the boiler through a communicating vessel. Placement cavities are installed on both sides of the float water level gauge, and a plurality of infrared pair detectors are installed in the placement cavities. The control component is electrically connected to the infrared pair detectors.

[0008] By adopting the above technical scheme, the two-color water level gauge and the float water level gauge can be connected to the internal space of the boiler through a communicating vessel, so that the water in the boiler can affect the two-color water level gauge and the float water level gauge, which is convenient for the staff to observe.

[0009] Further, the float water level gauge includes a housing, the housing is fixedly connected to the outer wall of the boiler, a perspective area is provided on the peripheral side wall of the housing, scale lines are provided on the housing, a transparent glass tube is arranged in the housing, the upper and lower ends of the transparent glass tube are respectively connected to the communicating vessel, and a float is arranged in the transparent glass tube. The float is on the induction path of the infrared pair detectors.

[0010] By adopting the above technical scheme, the infrared rays emitted by the emitter of the infrared pair detectors can pass through the transparent glass tube and then be received by the receiver at the other end. At the same time, the float can block the infrared rays, so that the receiver at this water level cannot receive the infrared signal emitted by the emitter.

[0017] The beneficial effects of the present utility model are as follows:

[0018] 1. Through the settings of the infrared pair emitter, the two-color water level gauge and the float water level gauge of the present utility model, the two different water level gauges can monitor the water level simultaneously, avoiding the abnormal observation results of the staff caused by the damage of a single water level gauge.

[0019] 2. Through the setting of the communicating vessel of the present utility model, the water in the boiler can affect the two-color water level gauge and the float water level gauge. At the same time, when the staff is not on-site, water leakage and damage will not occur due to too high water level.

[0020] 3. Through the setting of the camera of the present utility model, the staff can remotely and intuitively observe the water level scales of the two-color water level gauge and the float water level gauge through the camera, reducing the work intensity of the staff.

[0021] 4. Through the setting of the control component, the first solenoid valve, the second solenoid valve, the infrared pair - emission alarm, and the camera can be controlled by the control component. Thus, the intelligent control of the entire monitoring process can be realized, greatly improving the automation degree and reducing the working intensity of the staff.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to make the objectives, technical solutions, and advantages of the technical solutions of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the drawings of the specific embodiments of the present utility model. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0029] Referring to Figures 1 - 3 , an embodiment of the present utility model provides a boiler water level monitoring device, including a base 1, on which a boiler 2 is installed. A water inlet pipe 3 is connected to the top of the boiler 2, and the water inlet pipe 3 is controlled by a first solenoid valve 4. A water outlet pipe 5 is connected to the side wall surface of the boiler 2, and the water outlet pipe 5 is controlled by a second solenoid valve 6. Both the first solenoid valve 4 and the second solenoid valve 6 adopt the American Miller (Miller) pilot-operated solenoid valve of model ML175. A water level monitoring mechanism 7 is installed on the surface of the boiler 2. The water level monitoring mechanism 7 includes a two-color water level gauge 71 and a float type water level gauge 72 installed on the surface of the boiler 2. The two-color water level gauge 71 adopts the hw-yjl3 boiler two-color water level gauge. Both the two-color water level gauge 71 and the float type water level gauge 72 are connected to the inside of the boiler 2 through a communicating vessel 73. The two-color water level gauge 71 and the float type water level gauge 72 can be connected to the internal space of the boiler 2 through the communicating vessel 73, so that the water in the boiler 2 can affect the two-color water level gauge 71 and the float type water level gauge 72. The float type water level gauge 72 includes a housing 721, which is fixedly connected to the outer wall surface of the boiler 2. A perspective area is provided on the peripheral side wall of the housing 721, and scale lines are provided on the housing 721. A transparent glass tube 722 is provided in the housing 721. The upper and lower ends of the transparent glass tube 722 are respectively connected to the communicating vessel 73. A float 723 is arranged in the transparent glass tube 722. Placing cavities 74 are installed on both sides of the float type water level gauge 72, and a number of infrared opposed beam alarms 75 are installed in the placing cavities 74. The infrared opposed beam alarms 75 adopt the PAS-6520 infrared opposed beam alarms. A control component 100 is electrically connected to the infrared opposed beam alarms 75. The float 723 is on the induction path of the infrared opposed beam alarms 75. The infrared rays emitted by the transmitter of the infrared opposed beam alarms 75 can pass through the transparent glass tube 722 and then be received by the receiver at the other end. At the same time, the float 723 can block the infrared rays, so that the receiver at this water level cannot receive the infrared signal emitted by the transmitter, and then the control component 100 processes it, enabling the staff to remotely understand the water level height where the float 723 is located. The infrared opposed beam alarms 75 can make the monitoring process more intelligent.

[0030] Referring to Figures 1 - 3 , a remote monitoring mechanism 8 is arranged directly in front of the water level monitoring mechanism 7. The remote monitoring mechanism 8 includes a mounting table 81 opposite to the boiler 2. A camera 82 is installed on the mounting table 81, and the camera 82 is directly facing the two-color water level gauge 71 and the float type water level gauge 72. Through the camera 82, the staff can remotely and intuitively observe the water level scales of the two-color water level gauge 71 and the float type water level gauge 72.

[0031] Referring to Figures 1 - 3, further including a control component 100 installed on the boiler 2. The control component 100 includes a control module 200, a communication module 300, an alarm module 400, and a client 500. The control module 200 uses an STM32 microcontroller, and the communication module 300 uses 4G wireless communication technology. The control module 200 is electrically connected to the communication module 300, and the control module 200 is electrically connected to the alarm module 400 and the client 500 through the communication module 300. The control module 200 is electrically connected to the first solenoid valve 4, the second solenoid valve 6, the infrared pair detector 75, and the camera 82. Through the control module 200, the communication module 300, the alarm module 400, the client 500, the first solenoid valve 4, the second solenoid valve 6, the infrared pair detector 75, and the camera 82, the intelligent control of the entire monitoring process can be achieved.

[0032] The implementation method is specifically as follows: During normal use, the staff can remotely view the water level situation at the boiler 2 site through the camera 82, and control the first solenoid valve 4 to open through the control module 200, and then add water to the boiler 2. The water level can be visually observed through the two-color water level gauge 71 and the float water level gauge 72. When the normal water level is reached, the first solenoid valve 4 is closed. When the load in the boiler 2 changes, the water level will also change, and thus the water level observed through the two-color water level gauge 71 and the float water level gauge 72 will also change. A number of groups of infrared pair detectors 75 installed in the placement cavity 74 respectively correspond to the high water level, the upper limit of the normal water level, the lower limit of the normal water level, and the low water level from top to bottom. When the height of the float 723 in the float water level gauge 72 changes due to the water level, the infrared ray emitted by the emitter of the infrared pair detector 75 will be blocked by the float 723, and thus the receiver at the other end cannot receive the infrared ray. When the float 723 blocks the infrared ray emitted by the emitter of the infrared pair detector 75 at the high water level or the low water level, since the receiver at this water level cannot receive the infrared ray, a signal will be transmitted to the alarm module 400, and then the buzzer 401 and the flash lamp 402 will be activated. At the same time, this alarm information will be transmitted to the client 500 through the communication module 300, enabling the staff to remotely understand that the water level of the boiler 2 is abnormal. The staff can remotely control the opening and closing of the second solenoid valve 6 or the first solenoid valve 4 in a timely manner, and then take timely remedial measures for the boiler 2 to avoid safety accidents.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model.
