Description

Technical Field

[0001] The utility model belongs to the technical field of boiler water level measurement, in particular to a boiler water level measuring instrument. Background Art

[0002] A boiler water level gauge is a crucial device used to monitor the water level inside a boiler. Its primary function is to accurately measure the water level inside the boiler to ensure safe operation. Boiler water level gauges typically feature high precision, reliability, and stability. They provide timely feedback to operators, enabling them to take appropriate measures when water level anomalies occur, such as adjusting the water flow rate or stopping combustion. This prevents accidents caused by water shortages or overfilling, ensuring proper boiler operation and production safety.

[0003] Most of the existing boiler water level measuring instruments use manual observation, which not only wastes manpower, but also makes it inconvenient to effectively observe the water level when measuring the water level. Some boiler water level instruments include alarm devices, but the liquid level limit that triggers the alarm is fixed and cannot meet the measurement of different boiler water levels. Therefore, we propose a boiler water level measuring instrument. Utility Model Content

[0004] The purpose of this utility model is to provide a boiler water level measuring instrument, which is provided with a hollow threaded rod, specifically a handle fixedly connected to the top of the hollow threaded rod, an alarm fixedly connected to the top of the handle, a reed switch fixedly connected to the side of the inside of the hollow threaded rod near the bottom, a signal line fixedly connected to the top of the reed switch, and the signal line fixedly connected to the alarm. The user can adjust the position of the reed switch through the hollow threaded rod by turning the handle to make the distance between the magnetic plate and the reed switch longer or shorter, so as to measure different water levels required when the boiler is used, improve the scope of application of the device, and solve the problem that most of the existing boiler water level measuring instruments adopt manual observation, which not only wastes manpower, but also makes it inconvenient to effectively observe the water level when measuring the water level. In addition, some boiler water level meters include alarm devices, but the liquid level limit for triggering the alarm is fixed, which cannot meet the measurement of different boiler water levels.

[0005] In order to solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model discloses a boiler water level gauge, comprising a boiler water level gauge body and a liquid level tube. A floating block is slidably connected to the inner wall of the liquid level tube, a magnetic plate is fixedly connected to the top of the floating block, a plurality of grooves are formed on the outer surface of the floating block, and a ball is rotatably connected in each groove. The boiler water level gauge body is divided into upper and lower parts, wherein a hollow cylinder is fixedly connected to the top of the upper half of the boiler water level gauge body, a threaded hole shell is fixedly connected to the inner wall of the hollow cylinder, a connecting plate is fixedly connected to the bottom of the threaded hole shell, and a plurality of water holes are formed on the connecting plate. By providing the floating block, specifically, a plurality of grooves are formed on the outer surface of the floating block, the ball is rotatably connected to the inner wall of the groove, and the magnetic plate is fixedly connected to the top of the floating block, the floating block can be made of plastic with good buoyancy. When water enters the boiler water level gauge body, the water causes the floating block to float. Under the action of the water, the floating block rises on the inner wall of the liquid level tube through the ball, causing the magnetic plate to contact the reed switch, thereby generating an alarm when the water level reaches the predetermined level. This realizes the basic properties of internal measurement of the gauge and enhances the measurement accuracy of the gauge.

[0007] Furthermore, a hollow threaded rod is threadedly connected to the inner wall of the threaded hole shell, a reed switch is fixedly connected to the side of the inner wall of the hollow threaded rod near the bottom, and a signal line is fixedly connected to the top surface of the reed switch. By setting a hollow threaded rod, specifically a handle is fixedly connected to the top of the hollow threaded rod, an alarm is fixedly connected to the top of the handle, a reed switch is fixedly connected to the side of the inside of the hollow threaded rod near the bottom, a signal line is fixedly connected to the top of the reed switch, and the signal line is fixedly connected to the alarm. The user can adjust the position of the reed switch through the hollow threaded rod by turning the handle, so that the distance between the magnetic plate and the reed switch becomes longer or shorter, thereby measuring different water levels required when the boiler is used, thereby improving the scope of application of the device.

[0008] Furthermore, a handle is fixedly connected to the top of the hollow threaded rod. By providing the handle, the user can adjust the hollow threaded rod more conveniently, thereby improving the applicability of the device.

[0009] Furthermore, an alarm is fixedly connected to the top of the handle. By setting the alarm, the alarm function of the device is realized, ensuring that the device can avoid manual supervision of the liquid level pipe at all times when detecting the water level, thereby reducing manpower.

[0010] Furthermore, the top of the signal line is fixedly connected to the bottom of the alarm. By setting the signal line, the reed switch can transmit the working signal to the alarm, realizing the linkage between the two and ensuring the alarm properties of the device.

[0011] Furthermore, the floating block is slidably connected to the inner wall of the liquid level tube through a ball bearing that is rotated in the groove. By setting the ball bearing, the floating block can float stably inside the liquid level tube. At the same time, it also prevents the floating block from flipping over due to the force of water, causing the reed switch to fail to work effectively, thereby ensuring the stability of the internal structure of the device.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a hollow threaded rod, specifically, a handle is fixedly connected to the top of the hollow threaded rod, an alarm is fixedly connected to the top of the handle, a reed switch is fixedly connected to the side of the inside of the hollow threaded rod near the bottom, a signal line is fixedly connected to the top of the reed switch, and the signal line is fixedly connected to the alarm. The user can adjust the position of the reed switch through the hollow threaded rod by turning the handle, so that the distance between the magnetic plate and the reed switch becomes longer or shorter, thereby measuring different water levels required when the boiler is used, thereby improving the scope of application of the device.

[0014] 2. The utility model sets a floating block, specifically, a plurality of grooves are opened on the outer surface of the floating block, the inner wall of the groove is rotatably connected to the ball bearing, and the top of the floating block is fixedly connected to the magnetic plate. The floating block material can be set to plastic, which has good floating properties. When water enters the boiler water level measuring instrument body, the water can make the floating block float. The floating block rises on the inner wall of the liquid level tube under the action of the ball bearing and the water, so that the magnetic plate contacts the reed switch, realizing the alarm of the predetermined water level, realizing the basic properties of the internal measurement of the measuring instrument, and enhancing the measurement accuracy of the measuring instrument.
