[0002] With the continuous development of industrial production technology, various automatic control systems have been widely used in water treatment, chemical industry, energy and other industries. In these systems, liquid level detection and control is an important link. Accurate detection and effective control of liquid level directly affect the safety, stability and efficiency of the production process.

[0003] At present, common liquid level detection technologies include radar level gauges, ultrasonic level gauges, differential pressure level gauges, etc. Among them, radar level gauges are widely used in industrial production due to their advantages such as non-contact, no need to install pipelines, and not easily affected by medium characteristics. However, under certain special working conditions, such as high temperature, high pressure, corrosive media and other environments, the measurement accuracy of radar level gauges will be greatly affected, and even cause equipment damage and production interruption. Taking the vortex well water pool as an example, due to the high water temperature in the pool, especially the high water vapor content in winter, it is very easy to affect the measurement accuracy of the radar level gauge.

[0004] Therefore, there is a need for a liquid level monitoring device that is suitable for special working conditions and can accurately monitor the liquid level in the water pool to improve the safety and stability of the production process. Utility Model Content

[0005] The purpose of the utility model is to provide a liquid level monitoring device with high applicability and durability, which can ensure accurate monitoring of the pool liquid level under special working conditions such as high temperature, high pressure and high corrosion, and improve the safety and stability of the production process.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A liquid level monitoring device comprises a bracket arranged on the outer wall of one side of a pool, a limit alarm component detachably arranged on the bracket, and a trigger component adapted to the limit alarm component; the trigger component comprises a fixed pulley arranged on the top of the bracket, a steel wire rope overlapped on the fixed pulley, and a container 1 and a container 2 respectively arranged at both ends of the steel wire rope and both containing liquid, the container 1 being heavier than the container 2 and being placed in the pool, and the container 2 being suspended in the air under the gravity of the container 1 and adapted to the limit alarm component on the bracket.

[0008] A further improvement of the technical solution of the utility model is that a trigger baffle is horizontally arranged on the top of the second container, and one end of the trigger baffle is adapted to fit a limit alarm component, and the other end thereof is provided with a through hole extending upward and downward.

[0009] A further improvement of the technical solution of the utility model is that one end of the wire rope is connected to the second container through the trigger baffle, and the other end thereof passes through the through hole on the trigger baffle and is connected to the first container.

[0010] A further improvement of the technical solution of the utility model is that the limit alarm component includes two travel switches arranged on one side of the bracket close to the second container and an alarm electrically connected to the two travel switches respectively, and the two travel switches are respectively located on the upper and lower sides of the trigger baffle.

[0011] A further improvement of the technical solution of the utility model is that the interval between the two travel switches is adapted to the upper and lower limit water level difference of the pool.

[0012] A further improvement of the technical solution of the utility model is that a scale is arranged on one side of the bracket close to the container.

[0013] A further improvement of the technical solution of the utility model is that: container one is the same as container two, container one is full of water, and container two is not full of water; the water contained in container two is 1 / 2 of its volume.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0015] The liquid level monitoring device of the utility model has high applicability and durability. It can ensure accurate monitoring of the liquid level in the water pool under special working conditions such as high temperature, high pressure and high corrosion, effectively avoid interference from surrounding environmental factors, and improve the safety and stability of the production process. Moreover, due to its detachable mechanical structure, it is easier to repair and maintain than conventionally used radar level gauges, ultrasonic level gauges and differential pressure level gauges, saving economic costs.

[0016] The trigger component adopted by the utility model includes a container one arranged on a fixed pulley through a steel wire rope and a container two with a trigger baffle plate horizontally arranged on the top, wherein both the container one and the container two contain liquid, and the container one is heavier than the container two and is placed in a water pool, and the container two is suspended in the air under the gravity of the container one; the limit alarm component adopted by the utility model includes two travel switches respectively located on the upper and lower sides of the trigger baffle plate and an alarm device electrically connected to the two travel switches respectively, and the interval distance between the two travel switches is adapted to the upper and lower limit water level difference of the water pool. The trigger component cooperates with the limit alarm component. When the water level in the pool drops, the water buoyancy decreases, and the pulling force generated by container one on container two increases. At this time, container two drives the trigger baffle to rise under the action of container one. If the water in the pool drops to the lower limit water level, the trigger baffle contacts the travel switch on its upper side and an alarm is issued; when the water level in the pool rises, the water buoyancy increases, and the pulling force generated by container one on container two decreases. At this time, container two drives the trigger baffle to drop. If the water in the pool rises to the upper limit water level, the trigger baffle contacts the travel switch on its lower side and an alarm is issued, thereby completing accurate water level monitoring reminders.

[0020] The present invention is further described in detail below in conjunction with the embodiments:

[0021] like Figure 1 As shown, the utility model provides a liquid level monitoring device, including a bracket 6 and a limit alarm component and a trigger component that cooperate with each other. The bracket 6 is arranged on the outer wall of one side of the water tank 1. The limit alarm component and the trigger component are both detachably arranged on the bracket 6. Compared with conventionally used radar level gauges, ultrasonic level gauges and differential pressure level gauges, the utility model can effectively avoid interference from surrounding environmental factors, and the detachable mechanical structure adopted is more convenient for maintenance and repair, saving economic costs.

[0022] Specifically, the triggering component includes a fixed pulley 2, a steel wire rope 3, a container 1 4 and a container 2 5, wherein the fixed pulley 2 is arranged on the top of the bracket 6, the steel wire rope 3 is overlapped and wrapped around the fixed pulley 2, the container 1 4 and the container 2 5 are respectively arranged at the two ends of the steel wire rope 3, the container 1 4 and the container 2 5 are both closed containers, both of which contain liquid, preferably, the liquid is water, the container 1 4 is heavier than the container 2 5 and is placed in the pool 1, which is used to reflect the water level of the pool 1, the container 2 5 is suspended in the air under the gravity of the container 1 4, and is adapted to the limit alarm component on the bracket 6, and the container 2 5 and the container 1 4 are interlocked with the limit alarm component to send out upper and lower limit water level alarms. Preferably, the material, capacity, weight, volume and shape of the container 1 4 and the container 2 5 are the same, the interior of the container 1 4 is full of water, and the interior of the container 2 5 is not full of water, and more preferably, the water contained in the container 2 5 is 1 / 2 of its volume.

[0023] A trigger baffle 7 is also horizontally arranged on the top of the container 2 5. One end of the trigger baffle 7 is adapted to the limit alarm component, that is, it can trigger the upper and lower limit water level alarms, and the other end thereof is provided with a through hole 7-1 that passes through from top to bottom. One end of the steel wire 3 is connected to the container 2 5 through the trigger baffle 7, and the other end thereof passes through the through hole 7-1 on the trigger baffle 7 and is connected to the container 1 4. When the water level in the pool 1 is adjusted, the trigger baffle 7 can limit the containers 1 4 and 2 5 to keep them stable, and at the same time can prevent the water load from affecting the container 1 4 and causing it to have a large displacement.

[0024] The limit alarm component includes two travel switches 8 electrically connected to the alarm, and the two travel switches 8 are arranged on the side of the bracket 6 close to the container 2 5, and the two travel switches 8 are respectively located on the upper and lower sides of the trigger baffle 7, so that when the water level in the pool 1 changes to the upper and lower limit water levels, the trigger baffle 7 can contact the two travel switches 8 respectively.

A scale 9 is arranged on the side of the bracket 6 close to the container 1 4 to assist in monitoring the water level.

[0025] During operation, the trigger component cooperates with the limit alarm component. When the water level in the pool 1 drops, the water buoyancy decreases, and the pulling force generated by container one 4 on container two 5 increases. At this time, container two 5 drives the trigger baffle 7 to rise under the action of container one 4. If the water in the pool drops to the lower limit water level, the trigger baffle 7 contacts the travel switch 8 on its upper side and an alarm is sounded; when the water level in the pool 1 rises, the water buoyancy increases, and the pulling force generated by container one 4 on container two 5 decreases. At this time, container two 5 drives the trigger baffle 7 to drop. If the water in the pool rises to the upper limit water level, the trigger baffle 7 contacts the travel switch 8 on its lower side and an alarm is sounded, thereby completing accurate water level monitoring reminders.
