Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The preferred embodiment of the wastewater treatment liquid level monitoring device of this utility model has the following structure: Figures 1-4 As shown, the structure includes a housing 10. Specifically, the housing 10 includes an upper half-shell 11 and a lower half-shell 12 that is threadedly detachably connected to it. The inner cavity of the upper half-shell 11 is used to install the main control board 20, and the inner cavity of the lower half-shell 12 is used to install the battery 30. Both the upper half-shell 11 and the lower half-shell 12 are cylindrical in shape, and the diameter of the lower half-shell 12 is smaller than the diameter of the upper half-shell 11. The upper end of the lower half-shell 12 extends into the lower end of the upper half-shell 11 and is threadedly sealed to each other. A mounting plate 40 is provided on the lower outer wall of the lower half-shell 12, which can be connected to an external mounting bracket by screws. A wiring port 50 is provided on the outer wall of the upper half-shell 11 for the connection wire to pass through.

[0027] Furthermore, the structure also includes a lever arm 60 horizontally positioned below the outer shell 10, a support rod 70 longitudinally rotatably connected to one end of the lever arm 60, and a counterweight block 80 slidably positioned on the other end of the lever arm 60; the middle part of the lever arm 60 is longitudinally hinged to the lower end of the outer shell 10 through a hinge assembly. Specifically, the hinge assembly consists of two vertical triangular plates 90 facing each other, one straight edge of which is integrally connected to the bottom of the lower shell 12. The lever arm 60 is located in the middle of the two triangular plates 90 and is longitudinally rotatably connected to the triangular plates 90 through a hinge shaft 100, thereby achieving a stable connection.

[0028] Furthermore, a magnetic induction liquid level signal transmitter module 110 is provided on the lever arm 60 above its hinge axis; an adjustment component 120 for adjusting the tilt angle of the support rod 70 is provided on the lower side wall of the end of the lever arm 60 away from the counterweight 80; a float ball 130 is provided on the end of the support rod 70 away from the lever arm 60; during installation, the float ball 130 on the end of the support rod 70 is placed on the liquid surface, and then the vertical position of the housing 10 is adjusted to a suitable height, generally less than the overall length of the support rod 70, so that the support rod 70 is at an inclined angle; during operation, the float ball 130 moves up and down with the change in the liquid level in the sewage tank, thereby pushing the lever arm 60 and the magnetic induction liquid level signal transmitter module 110 to swing longitudinally, thereby converting the change in the liquid level position into an electrical signal and receiving it by the main control board 20, so that the main control board 20 can make corresponding control operations according to the predetermined rules.

[0029] Furthermore, in actual management, if the liquid level in the sewage tank needs to be adjusted, the tilt angle of the support rod 70 can be adjusted by adjusting component 120, thus adapting to different liquid level measurement scenarios in the sewage tank. There is no need to set up additional brackets to extend the overall structure of the device to a position closer to the center of the sewage tank, nor is there a need to readjust the overall position and height of the device again. This greatly facilitates the daily maintenance and inspection by staff.

[0030] In this embodiment, the upper end of the support rod 70 is provided with an upward-opening U-shaped hinge arm 140. The upper ends of both arms of the U-shaped hinge arm 140 are longitudinally hinged to the lever arm 60. The upper end of the support rod 70 passes through the U-shaped hinge arm 140 and extends between its two arms. One end of the adjusting component 120 extends between the two arms of the U-shaped hinge arm 140 and cooperates with the support rod 70. Specifically, the adjusting component 120 includes a movable push rod 121 that is slidably disposed parallel to the lower end face of the lever arm 60, and a limiting member 122 that positions the axial position of the movable push rod 121. A downward-sloping curved arm 12a is provided at one end near the support rod 70. When adjusted to the correct position, the inner wall of the curved arm 12a abuts against the side wall of the support rod 70 away from the counterweight 80. By adjusting the axial position of the movable push rod 121 and the curved arm 12a, the angle at which the support rod 70 can rotate can be adjusted. The farther the curved arm 12a is from the counterweight 80, the greater the angle at which the support rod 70 can rotate. At this time, the float 130 and the support rod 70 can be adapted to a higher liquid level. If the curved arm 12a is closer to the counterweight 80, the effect is the opposite.

[0031] In this embodiment, the movable push rod 121 is provided with a window 12b that runs longitudinally through it. The window 12b is long and one part of it extends to the lower end of the curved arm 12a. In the vertical state, the upper end of the support rod 70 extends into the window 12b to avoid the upper end of the support rod 70 being squeezed against the top of the inner wall of the curved arm 12a during the rotation process, thereby causing the curved arm 12a to deform upward.

[0032] In this embodiment, the limiting member 122 is columnar and vertically arranged. The upper end of the limiting member 122 is threadedly connected to the lever arm 60. The movable push rod 121 is provided with a clearance hole 12c along its length direction to avoid the limiting member 122. The lower end side wall of the limiting member 122 is coaxially provided with an annular boss c1. When assembled in place, the upper surface of the annular boss c1 slides against the lower surface of the movable push rod 121. By loosening the tightness of the limiting member 122, the axial position of the movable push rod 121 can be adjusted. After being in place, the limiting member 122 can be tightened again to limit the tilt angle of the support rod 70 through the positioned bent arm 12a.

[0033] In this embodiment, a receiving groove 61 for accommodating the movable push rod 121 is provided on the lower surface of the lever arm 60. The end of the receiving groove 61 facing the support rod 70 passes through the side wall of the lever arm 60. The receiving groove 61 not only guides the movable push rod 121, but also prevents the movable push rod 121 from protruding on the lever arm 60, making the overall structure more compact.

[0034] In this embodiment, the magnetic level signal transmitter module 110 includes a vertically arranged positioning shaft 111 and a magnet 112 embedded in the upper surface of the positioning shaft 111. Specifically, the magnet 112 is sheet-shaped and arranged in the left-right direction. The positioning shaft 111 is vertically connected to the lever arm 60. Furthermore, the magnetic level signal transmitter module also includes a magnetic induction sensor 113 located at the lower end of the housing 10. Specifically, multiple magnetic induction sensors 113 are evenly distributed on the outside of the deflection trajectory of the positioning shaft 111. The magnetic induction sensor 113 is generally a Hall sensor, but it can also be a magnetoresistive sensor. During operation, when the float 130 drives the support rod 70 and the lever arm 60 to deflect, the magnet 112 will move and trigger the magnetic induction sensors 113 at different positions, thereby triggering the main control board 20 to work and issue prompts or alarms to the management personnel.

[0035] In this embodiment, the lower end of the outer shell 10 is provided with an opening 150 and a sealing plastic plate 160 that seals the opening 150. The magnetic induction sensor 113 is disposed on the inner wall of the sealing plastic plate 150. The sealing plastic plate 150 not only facilitates disassembly and assembly, but also ensures the trigger sensitivity of the magnet 112 to the magnetic induction sensor 113.

[0036] In this embodiment, the counterweight 80 is damped and slidably connected to the lever arm 60 to balance the weight of the support rod 70 and the float 130.

[0037] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
