Abstract
Description
Technical Field
[0001] This utility model relates to the field of float level detection technology, and in particular to a multi-station linkage float level detection device. Background Technology
[0002] Float-type level gauges are commonly used liquid level detection devices. However, in mixed liquid level detection involving oil, the oil may solidify or the float may become stuck due to suspended solids, preventing the float from rotating and causing the level gauge to malfunction. Furthermore, existing float-type level gauges typically only detect one fixed position, making them unsuitable for multi-position level detection. Therefore, the present inventors aim to provide a multi-position linkage-type level float device that prevents the float from getting stuck and has multiple floats. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the main purpose of this utility model is to provide a multi-station linkage liquid level float device that is stable in signal triggering and capable of multi-point measurement.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-station linkage float level detection device, comprising a mounting frame, a plurality of limit switches disposed within the mounting frame, and a linkage float assembly corresponding to each limit switch; the mounting frame includes a fixed base plate and a cover disposed on the fixed base plate, the plurality of limit switches are all fixed on the fixed base plate, each linkage float assembly is provided with a float, a linkage, and a rotating plate rotatably connected to the linkage from bottom to top, the linkage passes through the fixed base plate, each limit switch includes a switch base and a switch head rotatably connected to the switch base, the switch head is fixedly connected to the rotating plate, the float drives the linkage to rise or fall, and the linkage drives the rotating plate and the switch head to rotate relative to the switch base, thereby realizing the opening and closing of the limit switch.
[0005] Preferably, a guide tube is provided on the fixed base plate at each link position.
[0006] Preferably, the connecting rod is rotatably connected to one end of the rotating plate via a pin and a cotter pin.
[0007] Preferably, the fixed base plate is provided with a mounting plate for fixing the limit switch.
[0008] Preferably, a junction box is provided on the fixed base plate.
[0009] This invention has the following advantages over existing technologies: The entire multi-station linkage-type liquid level float device is installed on top of the storage tank via a fixed base plate. This separates the limit switches from the floats in the mounting bracket, isolating the limit switches from the environment inside the storage tank and minimizing the influence of the liquid being detected on the limit switches. Several limit switches are configured one-to-one with the linkage float assembly. The detectable liquid level of each linkage float assembly is determined by the length of the linkage. When the float contacts the liquid, it causes the linkage to rise or fall. The linkage then drives the rotating plate and switch head to rotate relative to the switch base, thus opening and closing the limit switches. Triggering the limit switches through the rotational connection of the linkage and rotating plate avoids the influence of the liquid on the limit switch triggering, ensuring the smooth implementation of the detection process.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1As shown, a multi-position linkage 5 type liquid level float 4 device includes a mounting frame, a plurality of limit switches 3 disposed within the mounting frame, and a linkage 5 float 4 assembly corresponding to each limit switch 3. The mounting frame includes a fixed base plate 1 and a cover 2 covering the fixed base plate 1. The plurality of limit switches 3 are all fixed on the fixed base plate 1. Each linkage 5 float 4 assembly is arranged from bottom to top with a float 4, a linkage 5, and a rotating plate 6 rotatably connected to the linkage 5. The linkage 5 passes through the fixed base plate 1. Each limit switch 3 includes a switch base 31 and a switch head 32 rotatably connected to the switch base 31. The switch head 32 is fixedly connected to the rotating plate 6. The float 4 drives the linkage 5 to rise or fall. The linkage 5 drives the rotating plate 6 and the switch head 32 to rotate relative to the switch base 31, thereby realizing the opening and closing of the limit switch 3.
[0018] This solution presents a multi-station linkage 5-type liquid level float 4 device. Its working principle is as follows: the entire multi-station linkage 5-type liquid level float 4 device is installed on the top of the liquid storage tank 12 via a fixed base plate 1. This separates the limit switch 3 from the float 4 in the mounting bracket, isolating the limit switch 3 from the environment inside the liquid storage tank 12 and minimizing the influence of the liquid being detected on the limit switch 3. Several limit switches 3 are configured one-to-one with the linkage 5 float 4 assembly. The liquid level that each linkage 5 float 4 assembly can detect is determined by the length of the linkage 5. In this embodiment, four linkage 5 float 4 assemblies can detect four liquid levels in the liquid storage tank 12. When the float 4 contacts the liquid, it drives the linkage 5 to rise or fall. The linkage 5 drives the rotating plate 6 and the switch head 32 to rotate relative to the switch base 31, thereby opening and closing the limit switch 3. The rotational connection of the linkage 5 and the rotating plate 6 triggers the limit switch 3, avoiding the influence of the liquid on the triggering of the limit switch 3 and ensuring the smooth implementation of the detection process.
[0019] Preferably, a guide tube 7 is provided on the fixed base plate 1 at each position of the connecting rod 5. The function of the guide tube 7 is to limit the lifting and lowering process of the connecting rod 5, thereby improving the verticality of the lifting and lowering of the connecting rod 5 and improving the detection accuracy.
[0020] Preferably, the connecting rod 5 is rotatably connected to one end of the rotating plate 6 via a pin 8 and a cotter pin 9. This arrangement allows for convenient connection between the connecting rod 5 and the rotating plate 6.
[0021] Preferably, the fixed base plate 1 is provided with a mounting plate 10 for fixing the limit switch 3. The mounting plate 10 facilitates the placement of the limit switch 3.
[0022] Preferably, a junction box 11 is provided on the fixed base plate 1. The junction box 11 is electrically connected to four limit switches 3.
