Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of water tank level monitoring devices, specifically a water tank level monitoring and alarm device. Background Technology
[0002] Water tanks are containers used to hold water. They are classified into six types based on material: fiberglass water tanks, stainless steel water tanks, stainless steel-lined fiberglass water tanks, seawater fiberglass water tanks, enamel water tanks, and galvanized steel plate water tanks. Water tanks are generally equipped with HYFI remote-controlled electric level valves, water level monitoring systems, automatic cleaning systems, and self-cleaning sterilizers. The overflow pipe and drain pipe of the water tank are connected after the valve and are fitted with insect screens. The water tank should have two vent pipes at different heights (with insect screens). The water tank is equipped with internal and external ladders. Water tanks generally have inlet pipes, outlet pipes (domestic water outlet pipe, fire water outlet pipe), overflow pipes, and drain pipes. Water tanks are classified into five types according to function: domestic water tanks, fire water tanks, industrial water tanks, personal protective water tanks, and household water towers.
[0003] However, existing water tank level monitoring devices can only detect the overall liquid level of the water tank. When the water tank is tilted, the liquid level will not change, and the monitoring data of the water tank level monitoring device will remain normal, which is not conducive to the safe use of the water tank. Therefore, it does not meet the existing needs. In response, we have proposed a water tank level monitoring and alarm device. Utility Model Content
[0004] The purpose of this utility model is to provide a water level monitoring and alarm device for water tanks, so as to solve the problems mentioned in the background art, that the water level monitoring device can only detect the overall liquid level of the water tank, and the liquid level of the water tank will not change when the water tank is tilted. At this time, the monitoring data of the water level monitoring device remains normal, which is not conducive to the safe use of the water tank.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water level monitoring and alarm device for a water tank, comprising a water tank, a marker rod slidably mounted through the top of the water tank, a trigger plate fixed to the top of the marker rod, an alarm button fixed to the upper surface of the water tank, a fixing block fixed to the bottom of the marker rod, a connecting flexible plate detachably mounted on all four sides of the fixing block, an auxiliary buoyancy block fixed to the bottom surface of the end of the connecting flexible plate away from the fixing block, and a central buoyancy block fixed to the bottom surface of the fixing block.
[0006] Preferably, the length of the trigger plate is three to five times the diameter of the marker rod, and the alarm button is located directly below the end of the trigger plate away from the marker rod.
[0007] Preferably, the fixing block has a cross structure and each of the four ends has a mounting slot, and one end of the connecting flexible plate is detachably installed inside the mounting slot.
[0008] Preferably, the outer surface of the marker rod is engraved with a height display scale.
[0009] Preferably, the end of the connecting flexible plate inserted into the inner side of the mounting slot is connected to a connecting pin, and the two ends of the connecting pin are rotatably inserted into the fixed block.
[0010] Preferably, pressure sensors are fitted on the outer sides of both ends of the connecting pin. The pressure sensors are located between the connecting flexible plate and the fixing block, and the sum of the thickness of the connecting flexible plate and the two pressure sensors is consistent with the internal height dimension of the mounting slot.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention uses four connecting flexible plates to connect four auxiliary buoyancy blocks to fixed blocks. By using the central buoyancy block and auxiliary buoyancy blocks, the water level at the center of the water tank and the water level at the four corners can be detected simultaneously. When the water tank tilts, it can be detected immediately and the direction of tilt can be determined. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] like Figures 1 to 3As shown, a water level monitoring and alarm device for a water tank includes a water tank 1. A marker rod 2 is slidably installed through the top of the water tank 1. The outer surface of the marker rod 2 is engraved with a height display scale. A trigger plate 4 is fixed to the top of the marker rod 2. An alarm button 3 is fixed to the upper surface of the water tank 1. A fixing block 5 is fixed to the bottom of the marker rod 2. A connecting flexible plate 7 is detachably installed on all four sides of the fixing block 5. An auxiliary buoyancy block 8 is fixed to the bottom surface of the end of the connecting flexible plate 7 away from the fixing block 5. A central buoyancy block 6 is fixed to the bottom surface of the fixing block 5. The central buoyancy block 6 and the auxiliary buoyancy block 8 are in contact with the water inside the water tank. When the water volume inside the water tank changes, the central buoyancy block 6 and the auxiliary buoyancy block 8 rise and fall with the change of the water volume inside the water tank, thereby changing the position of the marker rod 2, so as to monitor the water level inside the water tank.
[0019] The length of the trigger plate 4 is three to five times the diameter of the marker rod 2. The alarm button 3 is located directly below the end of the trigger plate 4 away from the marker rod 2. When the liquid level inside the water tank reaches its lowest point, the trigger plate 4 contacts the alarm button 3 to trigger the alarm program, thereby reminding the staff to fill the water tank with water or to inspect the water tank.
[0020] The fixing block 5 has a cross structure and each of its four ends has a mounting slot 9. One end of the connecting flexible plate 7 is detachably installed inside the mounting slot 9. The end of the connecting flexible plate 7 that is inserted into the mounting slot 9 is connected to a connecting pin. The two ends of the connecting pin are rotatably inserted into the fixing block 5. Pressure sensors 10 are sleeved on the outer sides of both ends of the connecting pin. The pressure sensors 10 are located between the connecting flexible plate 7 and the fixing block 5. The sum of the thickness of the connecting flexible plate 7 and the two pressure sensors 10 is consistent with the internal height of the mounting slot 9. When the water tank tilts, the auxiliary buoyancy block 8 on the tilted side of the water tank will move upward due to the tilt of the water tank. At this time, the connecting flexible plate 7 tilts upward and squeezes the pressure sensor 10 located above it. The pressure data value of the pressure sensor 10 is used to determine whether the water tank is tilted and the degree of tilt. The greater the degree of tilt of the water tank, the greater the pressure data detected by the pressure sensor 10.
[0021] Working Principle: When storing water in the tank, the water inside generates buoyancy on the central buoyancy block 6 and the auxiliary buoyancy block 8. As the water level rises, the central buoyancy block 6 and the auxiliary buoyancy block 8 also rise, causing the connecting flexible plate 7 and the fixing block 5 to rise simultaneously. At this time, the marker rod 2 extends from the water tank 1, increasing the distance between the trigger plate 4 and the alarm button 3. When the water level drops, the fixing block 5 and the connecting flexible plate 7 descend, causing the marker rod 2 to lower the trigger plate 4. The trigger plate 4 then approaches the alarm button 3. When the water level drops to the warning line, the trigger plate 4 contacts the alarm button 3, triggering the water tank's alarm program. If the water tank tilts during use... Marker rod 2 tilts simultaneously with the water tank, but the liquid level inside the tank remains unchanged. This constant liquid level causes the four auxiliary buoyancy blocks 8 to be at the same height, resulting in the auxiliary buoyancy blocks 8 on the tilted side of the tank exerting an upward force on the connecting flexible plate 7. This causes the connecting flexible plate 7 to bend and apply pressure to the pressure sensor 10 above it. The pressure value of the pressure sensor 10 increases; the greater the tilt of the water tank, the greater the pressure data detected by the pressure sensor 10. The pressure data value of the pressure sensor 10 determines whether the water tank is tilted and the degree of tilt. By using the different pressure values of all pressure sensors 10, the tilt of the water tank can be detected immediately, and protective measures can be taken to ensure the safety of the water tank during use.
