[0032] Please refer to Figures 1-6 The utility model provides a kind of technical scheme: a liquid level controller for liquid unloading, including hollow tube 1 and terminal box 2, terminal box 2 is threadedly connected in the upper end of hollow tube 1, float limit component, float limit component is arranged in the inside of hollow tube 1, float limit component includes fixed block 5, fixed block 5 is fixedly connected in the inside of hollow tube 1, the inner wall of fixed block 5 is slidably connected with movable rod 6, a plurality of first limit slot 7 are set on the surface of movable rod 6, reset spring 8 is arranged in the inside of hollow tube 1, the two ends of reset spring 8 are fixedly connected on movable rod 6 and hollow tube 1, two dry reed tubes 16 are fixedly connected in the inside of hollow tube 1, rotating shaft 14 is rotatably connected in the inside of hollow tube 1, the surface of rotating shaft 14 is fixedly connected with limit plate 15, limit plate 15 is sleeved with torsion spring 17 on the surface, and the two ends of torsion spring 17 are fixedly connected with limit plate 15 and hollow tube 1 respectively.

[0033] The surface of hollow tube 1 is provided with sliding slot 10, and the surface of hollow tube 1 is slidably sleeved with movable ring 9, the inner wall of movable ring 9 is fixedly connected with connecting block 11, and the surface of movable ring 9 is fixedly connected with float ball 12.

[0034] The number of rotating shaft 14, limit plate 15 and torsion spring 17 is all ten, which are symmetrically arranged on the left and right sides in the inside of hollow tube 1.

[0035] Sliding slot 10, connecting block 11 and float ball 12 are all two, which are symmetrically arranged on the left and right sides of hollow tube 1, and the inside of float ball 12 close to dry reed tube 16 side is fixedly connected with magnetic substance.

[0036] The opposite surface of the two connecting blocks 11 is provided with a plurality of second limiting grooves 13.

[0037] The upper end of the ten limiting plates 15 is arc-shaped, and the lower end of the ten limiting plates 15 is plate-shaped.

[0038] The shape of the five first limiting grooves 7 is annular.

[0039] The surface of the hollow pipe 1 is fixedly connected with four first connecting rods 3, and the surface of the junction box 2 is fixedly connected with four second connecting rods 4.

[0040] In use of the device, the movable rod 6 can slide up and down in the hollow pipe 1, the lower end of the limiting plate 15 is extruded by the movable rod 6, so that the limiting plate 15 rotates around the rotating shaft 14, the limiting plate 15 twists the torsional spring 17, the inside of the storage tank stores liquid, the float ball 12 floats on the surface of the liquid by the buoyancy of the float ball 12 itself, the float ball 12 moves upward under the action of the buoyancy, the float ball 12 drives the movable ring 9 and the connecting block 11 to move, so that the connecting block 11 slides in the sliding groove 10, the position of the float ball 12 is automatically adjusted by the buoyancy of the liquid and the height of the liquid in the storage tank, and the position of the float ball 12 is adjusted according to the liquid level under the action of the buoyancy when the liquid in the storage tank needs to be unloaded.

[0041] When the movable ring 9 and the float ball 12 descend to a certain extent, and the movable ring 9 and the float ball 12 move to the vicinity of the float ball 12 to the reed tube 16, the reed tube 16 is electrically connected with the junction box 2 through the wires, the reed tube 16 is attracted by the magnetic material in the float ball 12, the magnetic material attracts the magnetic metal sheet in the reed tube 16, the magnetic metal sheet and the non-magnetic metal sheet are conductive, the current passes through, and then the alarm device in the junction box 2 gives an alarm.

[0042] Since the junction box 2 needs to be regularly disassembled and repaired during use of the liquid level controller to maintain normal use of the liquid level controller, when the junction box 2 needs to be disassembled, the first connecting rod 3 and the second connecting rod 4 are used, the second connecting rod 4 on the surface of the junction box 2 is rotated, the first connecting rod 3 and the second connecting rod 4 can be used as a fixed point, which is convenient for installation and maintenance personnel to operate, and the first connecting rod 3 and the second connecting rod 4 can be used as a support point when the hollow pipe 1 and the junction box 2 are disassembled or reinstalled, so that the junction box 2 can be quickly installed and disassembled.

[0043] When the junction box 2 is disassembled, the junction box 2 is separated from the hollow pipe 1, and the movable rod 6 moves upward under the action of the reset spring 8. In the process of moving the movable rod 6, since the limiting plate 15 is connected with the torsional spring 17, and the torsional spring 17 is in a torsional state, when the movable rod 6 moves, the first limiting groove 7 contacts the limiting plate 15. When the limiting plate 15 contacts the first limiting groove 7, due to the gap of the first limiting groove 7 between the movable rod 6 and the limiting plate 15, the limiting plate 15 rotates around the pivot 14 under the action of the torsional spring 17 and contacts the inner wall of the first limiting groove 7. When the limiting plate 15 rotates, the limiting plate 15 rotates towards the connecting block 11 to limit the upper end of the connecting block 11. The first limiting groove 7 limits the position of the limiting plate 15, which is convenient for limiting the position of the movable ring 9 and the position of the floating ball 12.

[0044] Due to the different liquid levels in the storage tank, the limiting plate 15 may not be accurately positioned on the upper end of the connecting block 11. When the movable ring 9 moves under the action of the buoyancy of the floating ball 12, when the connecting block 11 moves to the vicinity of the corresponding pivot 14, that is, the movable ring 9 and the connecting block 11 are located on both sides of the limiting plate 15. When the limiting plate 15 rotates, it will be blocked by the connecting block 11. Since the second limiting groove 13 is provided on the surface of the connecting block 11, the limiting plate 15 can be clamped in the corresponding second limiting groove 13, which can also limit the connecting block 11, preventing the floating ball 12 from moving due to factors such as bumps and vibrations during movement or transportation, and improving the stability of the position of the floating ball 12.

[0045] Further, when the junction box 2 is disassembled, the movable rod 6 moves under the action of the reset spring 8, and the position of the movable ring 9 and the floating ball 12 is limited by the limiting plate 15, which is convenient for limiting the position of the floating ball 12, preventing the floating ball 12 from moving due to factors such as bumps and vibrations during movement or transportation, and improving the stability of the position of the floating ball 12. This helps to maintain the accurate correspondence between the floating ball and the liquid level, and improves the accuracy of measurement.

[0046] By using the first connecting rod 3 and the second connecting rod 4, by rotating the second connecting rod 4 on the surface of the junction box 2, the first connecting rod 3 and the second connecting rod 4 can be used as a fixed point, which is convenient for installation and maintenance personnel to operate. When disassembling or reinstalling the hollow pipe 1 and the junction box 2, the first connecting rod 3 and the second connecting rod 4 can be used as a support point, which can quickly install and disassemble the junction box 2, and is convenient for repairing and maintaining the junction box 2, and prolongs the service life of the junction box 2.
