Description

Technical Field

[0001] This utility model relates to the field of magnetic level gauge technology, and in particular to a magnetic level gauge warning system for water tanks. Background Technology

[0002] To monitor the water level in the water tanks of coal mine heat exchange stations, magnetic level gauges are installed on the tanks, and alarm switches are also installed on the magnetic level gauges. When the water level in the tank reaches the upper or lower limit, the alarm switch sends an alarm signal. Currently, the alarm switch is mostly fixed to the outside of the magnetic level gauge by strapping it on, which makes it inconvenient to adjust the position of the alarm switch on the magnetic level gauge and needs improvement. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a magnetic float level gauge warning system for water tanks, which facilitates the adjustment of the position of the alarm switch on the magnetic float level gauge.

[0004] Technical Solution: To achieve the above objectives, the present invention provides a magnetic level gauge warning system for water tanks, comprising an alarm and a magnetic level gauge installed on the water tank.

Attached Figure Description

[0012] Appendix Figure 1 This is a schematic diagram of a magnetic level gauge and alarm switch on a water tank.

[0013] Appendix Figure 2 This is a schematic diagram of the sliding seat. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As attached Figures 1 to 2 The magnetic level gauge warning system for water tanks includes an alarm 1 and a magnetic level gauge 3 installed on the water tank 2. The working principle of the magnetic level gauge 3 is mainly based on buoyancy and magnetic coupling. The magnetic level gauge 3 includes an indicator and a measuring tube. The measuring tube is connected to the inside of the water tank 2, forming a communicating vessel, so that the measuring tube matches the liquid level of the water tank 2. There is a magnetic float inside the measuring tube. When the liquid level in the water tank 2 rises or falls, the magnetic float in the measuring tube also rises or falls accordingly. The permanent magnet inside the float transmits the signal to the magnetic flip indicator through magnetic coupling, driving the red and white flip columns to rotate 180°. When the liquid level rises, the flip column changes from white to red; when the liquid level falls, the flip column changes from red to white. The red-white boundary of the indicator is the actual height of the liquid level in the water tank 2, thus achieving a clear indication of the liquid level in the water tank 2.

[0016] An alarm switch 4 is installed on one side of the magnetic level gauge 3. The alarm switch 4 contains a reed switch. When the magnetic float in the magnetic level gauge 3 moves up and down with the liquid level, the reed switch at the corresponding liquid level position is attracted or deactivated by the magnetic field inside the float. This change is converted into a passive switch signal output by a conversion module, thereby realizing the high and low liquid level alarm function. The alarm switch 4 is electrically connected to the alarm 1, and the signal output by the alarm switch 4 is transmitted to the alarm 1 to trigger an alarm.

[0017] As attached Figure 1As shown, a bracket 5 is installed on the water tank 2, and a sliding seat 6 is provided on the bracket 5. The alarm switch 4 is fixed on the sliding seat 6. The sliding seat 6 can move up and down on the bracket 5 to adjust its position. The alarm switch 4 can slide and move up and down on the bracket 5 with the sliding seat 6 to adjust the position of the alarm switch 4 relative to the magnetic float level gauge 3. This solves the problem of difficulty in adjusting the position of the alarm switch 4 when it is tied to the magnetic float level gauge 3.

[0018] A clamping assembly and an adjusting assembly are provided on the sliding seat 6. The clamping assembly clamps the alarm switch 4 to fix the alarm switch 4 on the sliding seat 6. The adjusting assembly can adjust the position of the sliding seat 6 on the bracket 5, so that the sliding seat 6 is closer to or farther away from the magnetic float level gauge 3, thereby ensuring that the alarm switch 4 fixed on the sliding seat 6 is close to one side of the magnetic float level gauge 3, ensuring the sensitivity of the alarm switch 4.

[0019] As attached Figure 1 As shown, the bracket 5 includes a vertical guide rod 7, which is adjacent to the magnetic level gauge 3. The upper and lower ends of the vertical guide rod 7 are respectively fixed to the outer wall of the water tank 2. (See attached diagram) Figure 2 As shown, a square collar is provided on one side of the sliding seat 6, and an adjustment hole 8 is inside the square collar. The vertical guide rod 7 is inserted into the adjustment hole 8. The adjustment hole 8 is a square hole, and the vertical guide rod 7 is a square rod. The width of the cross-section of the square rod is the same as the width of the adjustment hole 8, and the length of the cross-section of the square rod is less than the length of the adjustment hole 8. This allows the sliding seat 6 to move horizontally relative to the vertical guide rod 7 along the length direction of the adjustment hole 8, thereby allowing the sliding seat 6 to move closer to or further away from the magnetic float level gauge 3. This ensures that the alarm switch 4 fixed on the sliding seat 6 can be tightly attached to one side of the magnetic float level gauge 3.

[0020] On both sides of the length of the adjusting hole 8, there are opposing bolts 9. The front ends of the opposing bolts 9 abut against the vertical guide rod 7, so that the sliding seat 6 can be fixed on the vertical guide rod 7. Specifically, two opposing bolts 9 are provided on the side of the adjusting hole 8 near the magnetic float level gauge 3, that is, the two opposing bolts 9 are located at the top and bottom ends of the sliding seat 6, respectively. On the side of the adjusting hole 8 away from the magnetic float level gauge 3, there is one opposing bolt 9 in the middle position. (See attached diagram) Figure 2 As shown, the three opposing bolts 9 cooperate with each other to stably fix the sliding seat 6 to the vertical guide rod 7.

[0021] The clamping assembly includes a top plate 10 and a bottom plate 11 disposed opposite each other on the sliding seat 6. The top plate 10 has a vertical screw hole, into which a clamping bolt 12 is installed. The clamping bolt 12 can be screwed downwards to press the alarm switch 4 against the bottom plate 11, thereby fixing the alarm switch 4. A pressure plate 16 is provided at the lower end of the clamping bolt 12 to prevent the clamping bolt 12 from damaging the alarm switch 4 and to clamp the alarm switch 4 more stably.

[0022] The base plate 11 has an opening 13; the bottom of the alarm switch 4 is provided with a wiring terminal 14, and the alarm switch 4 is electrically connected to the alarm 1 through the wiring terminal 14, with the wiring terminal 14 extending out from the opening 13 of the base plate 11.

[0023] The bracket 5 is equipped with two alarm switches 4, which monitor the upper and lower limits of the water level in the water tank 2. The alarm device 1 includes two audible and visual alarm lights 15, and the two alarm switches 4 are electrically connected to the two audible and visual alarm lights 15 respectively.

[0024] In this utility model, when adjusting the position of the alarm switch 4, first loosen all three counterbolts 9, then slide the sliding seat 6 to the position to be adjusted, first tighten the two counterbolts 9 at the top and bottom of the sliding seat 6 so that the alarm switch 4 is close to one side of the magnetic float level gauge 3, and then tighten the counterbolt 9 in the middle of the sliding seat 6 so that the three counterbolts 9 work together to fix the sliding seat 6 in the position to be adjusted.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
