Description

TECHNICAL FIELD

[0001] The present application relates to the field of water level monitoring, in particular to a water level monitoring device. BACKGROUND

[0002] Water pool water level monitoring is an important measure to ensure water supply safety and improve management efficiency. Its importance is reflected as follows: (1) Ensure water supply. Real-time monitoring can ensure that the water pool is always within a reasonable water level range, avoiding sudden water shortage or insufficient water pressure problems, especially during peak water consumption periods (such as early morning and evening); (2) Prevent water pollution. When the water level is too low, the sediments at the bottom of the pool may be stirred up, resulting in an increase in suspended solids and turbidity of the water; a reasonable water level can reduce the risk of pollutants entering the water supply pipeline; (3) Respond to emergencies. In the event of pipeline rupture, natural disasters (such as earthquakes, floods), etc. Emergency events, water level monitoring systems can quickly detect abnormalities, helping repair personnel locate problems and shorten recovery time.

[0003] The existing water pool water level monitoring technology includes float ball type water level meter, pressure type water level meter, and ultrasonic water level meter. Among them, the float ball type water level meter is widely used in water pool water level monitoring due to its simple structure, easy installation and maintenance. Applications include: float ball, connecting rod, guide rod, and contact switch (or potentiometer) basic components, without complex circuit or precision sensor. However, the existing float ball type water level meter lacks an alarm function and cannot alarm according to changes in the water level of the pool. SUMMARY

[0004] The present application aims to provide a water level monitoring device to solve the problem of the lack of alarm function in the existing float ball type water level meter, which cannot alarm according to changes in the water level of the pool.

[0005] To achieve the above purpose, the present application provides the following technical solutions: A water level monitoring device, comprising a support and an alarm, the support is fixedly provided with a liquid level pipe, a first carbon rod electrode is fixedly arranged at the top of the inner side of the liquid level pipe, a guide rod is vertically slidably connected to the liquid level pipe, the guide rod is detachably connected to a connecting rod, the connecting rod is fixedly provided with a float ball, a second carbon rod electrode is fixedly arranged at the top of the guide rod, and the first carbon rod electrode, the alarm, and the second carbon rod electrode form a closed electric circuit.

[0006] The working principle and beneficial effects of the present application are as follows: When monitoring the water level of the water tank, the bracket is fixedly installed on the water tank, and the floating ball is suspended on the liquid surface in the water tank. When the water level of the water tank changes, the floating ball moves up and down according to the height of the water level line, thereby driving the guide rod to move up and down in the liquid level pipe. When the second carbon rod pole on the guide rod contacts the first carbon rod pole, the first carbon rod pole, the alarm and the second carbon rod pole form a closed electric circuit, and the electric circuit is conducted to make the alarm alarm.

[0007] Further, the inside of the liquid level pipe is provided with a limiting groove, and the guide rod is provided with a limiting block in sliding connection with the limiting groove. Through the cooperation of the limiting groove and the limiting block, the guide rod is prevented from coming out of the liquid level pipe.

[0008] Further, the connecting rod and the guide rod are connected in a clamping manner. When the floating ball is used in water level monitoring, the alga on the surface of the floating ball will affect the monitoring result because the water tank for daily use is exposed to sunlight. The alga adhered to the floating ball increases the weight of the floating ball and changes the buoyancy characteristics thereof. If the buoyancy is not enough to offset the added weight, the floating ball sinks, thereby underestimating the actual water level. The alga makes the surface of the floating ball rough, increases the friction with the water body or the guide structure, and reduces the monitoring sensitivity. Therefore, the connecting mode of the connecting rod and the guide rod is set as clamping, so that the new floating ball can be conveniently replaced.

[0009] Further, the bracket comprises a vertical beam, a first cross beam and a second cross beam, the first cross beam and the vertical beam are vertically and slidably connected, the vertical beam is fixedly provided with a first air cylinder for driving the first cross beam to ascend and descend, the first cross beam is fixedly provided with a second air cylinder, the liquid level pipe and the movable end of the second air cylinder are fixedly connected, the second cross beam is fixedly provided with a motor, and the movable end of the motor is provided with a cleaning cylinder.

[0010] When the floating ball grows alga, the first cross beam is driven by the first air cylinder to move upward, so that the floating ball is separated from the water surface. Then, the second air cylinder drives the liquid level pipe to slide horizontally, so that the floating ball moves to the upper side of the cleaning cylinder. Then, the first cross beam is driven by the first air cylinder to move downward, so that the floating ball enters the cleaning cylinder. The alga on the floating ball is cleaned by rotating the cleaning cylinder driven by the motor. After cleaning, the floating ball is reset to continue the water level monitoring work.

[0011] Further, the vertical beam is further vertically and slidably connected with a limiting beam located between the first cross beam and the second cross beam, the limiting beam is provided with a through groove for the connecting rod to pass through, the connecting rod is fixedly provided with a limiting plate with a size larger than that of the through groove, and the movable end of the first air cylinder is fixedly connected with the limiting beam.

[0012] Since the guide rod is vertically sliding in the liquid level tube, when the cleaning cylinder cleans the algae on the floating ball, if the movement of the guide rod, connecting rod and floating ball is not limited, the cleaning effect on the floating ball will be poor when the cleaning cylinder rotates. Therefore, the first cylinder drives the first cross beam to move upward, so that the floating ball is separated from the water surface, the limiting block slides downward to the bottom in the limiting groove, and the limiting groove can prevent the connecting rod and floating ball from moving downward. At this time, the second cylinder drives the liquid level tube to slide horizontally, so that the floating ball moves to the top of the cleaning cylinder, the connecting rod is clamped into the through groove, the limiting plate is clamped below the limiting beam, and the limiting plate and the limiting beam are in contact. Then, the limiting beam prevents the connecting rod and the floating ball from moving upward, and then the first cylinder drives the first cross beam and the limiting beam to descend, so that the floating ball extends into the cleaning cylinder. Since the floating ball moves up and down, the floating ball remains stationary, so that the rotation of the cleaning cylinder quickly cleans the algae on the floating ball, improving the cleaning effect on the floating ball.

[0013] Further, the inside of the cleaning cylinder is fixedly provided with a sponge pad. The sponge pad improves the algae cleaning effect. BRIEF DESCRIPTION OF DRAWINGS

[0015] The following will be further described in detail through specific embodiments: The reference signs in the drawings of the specification include: floating ball 1, connecting rod 2, guide rod 3, second carbon rod pole 4, liquid level tube 5, first carbon rod pole 6, first cylinder 7, first cross beam 8, cleaning cylinder 9, second cross beam 10, motor 11, limiting groove 12, limiting beam 13, limiting plate 14, through groove 15, sponge 16.

[0016] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0017] Example 1: A water level monitoring device, such as Figure 1 As shown, it includes a bracket and an alarm, a liquid level tube 5 is fixedly provided on the bracket, a first carbon rod electrode 6 is fixedly provided on the top of the inner side of the liquid level tube 5, the liquid level tube 5 is vertically slidably connected to a guide rod 3, a connecting rod 2 is clamped on the bottom of the guide rod 3, a float 1 is fixed on the connecting rod 2, a second carbon rod electrode 4 is fixed on the top of the guide rod 3, and the first carbon rod electrode 6, the alarm and the second carbon rod electrode 4 form a closed electrical circuit.

[0018] When monitoring the water level of a domestic water pool, the bracket is fixedly installed on the pool, and the float 1 is suspended on the liquid surface in the pool. When the water level in the pool changes, the float 1 moves up and down according to the height of the water level line, thereby driving the guide rod 3 to move up and down in the liquid level tube 5. When the second carbon rod electrode 4 on the guide rod 3 contacts the first carbon rod electrode 6, the first carbon rod electrode 6, the alarm and the second carbon rod electrode 4 form a closed electrical circuit. The electrical circuit is turned on, causing the alarm to sound an alarm.

[0019] Example 2: The difference from Example 1 is that the bracket includes a vertical beam, a first horizontal beam 8 and a second horizontal beam 10, the first horizontal beam 8 and the vertical beam are vertically slidably connected, the vertical beam is fixedly provided with a first cylinder 7 for driving the first horizontal beam 8 to rise and fall, the first horizontal beam 8 is fixedly provided with a second cylinder, the liquid level tube 5 and the movable end of the second cylinder are fixedly connected, the liquid level tube 5 and the first horizontal beam 8 are horizontally slidably connected, the second horizontal beam 10 is fixedly provided with a motor 11, the movable end of the motor 11 drives a cleaning cylinder 9, and the inner side wall of the cleaning cylinder 9 is fixedly provided with a sponge 16.

[0020] like Figure 3 and Figure 4 As shown, when moss grows on the float 1, the first cylinder 7 drives the first crossbeam 8 to move upward, so that the float 1 is out of the water surface, as shown in FIG. Figure 5 As shown, a limiting groove 12 is provided inside the liquid level tube 5, and a limiting block is fixedly provided on the guide rod 3 and is slidably connected to the limiting groove 12. The limiting groove 12 and the limiting block cooperate to prevent the guide rod 3 from falling out of the liquid level tube 5.

[0021] Then the second cylinder drives the liquid level tube 5 to slide horizontally, so that the float 1 moves to the top of the cleaning cylinder 9, and then the first cylinder 7 drives the first beam 8 to move downward. Figure 6 As shown, the float 1 enters the cleaning cylinder, and the motor 11 drives the cleaning cylinder 9 to rotate. The sponge 16 cleans the moss on the float 1. After the cleaning is completed, the float 1 is reset to continue the water level monitoring work.

[0022] Example 3: The difference from example 2 is that, as shown in Figure 7 and Figure 8 The vertical beam is further vertically slidingly connected with a limiting beam 13 between the first horizontal beam 8 and the second horizontal beam 10, the limiting beam 13 is provided with a through slot 15 for the connecting rod 2 to pass through, the connecting rod 2 is fixedly provided with a limiting plate 14 with a size larger than that of the through slot 15, and the movable end of the first air cylinder 7 is fixedly connected with the limiting beam 13.

[0023] Since the guide rod 3 is vertically sliding in the liquid level pipe 5, if the movement of the guide rod 3, the connecting rod 2 and the floating ball 1 is not limited when the cleaning cylinder 9 cleans the algae on the floating ball 1, the cleaning effect on the floating ball 1 will be poor when the cleaning cylinder 9 rotates. Therefore, the first air cylinder 7 drives the first horizontal beam 8 to move upward, so that the floating ball 1 is separated from the water surface, and the limiting block slides downward to the bottom in the limiting slot 12, which can prevent the connecting rod 2 and the floating ball 1 from moving downward. At this time, the second air cylinder drives the liquid level pipe 5 to slide horizontally, so that the floating ball 1 moves to the upper side of the cleaning cylinder 9, the connecting rod 2 is clamped into the through slot 15, the limiting plate 14 is clamped below the limiting beam 13, and the limiting plate 14 and the limiting beam 13 are in contact. Then, the limiting beam 13 prevents the connecting rod 2 and the floating ball 1 from moving upward, and then the first air cylinder 7 drives the first horizontal beam 8 and the limiting beam 13 to descend, so that the floating ball 1 extends into the cleaning cylinder 9. Since the floating ball 1 moves up and down, the floating ball 1 remains stationary, so that the rotation of the cleaning cylinder 9 quickly cleans the algae on the floating ball 1, and improves the cleaning effect on the floating ball 1.
