Floating ball structure with self weight

By setting a partition plate in the float structure to divide the float cavity into a sealed cavity and an open cavity, the weight of the float can be adjusted by using the buoyancy of the gas in the sealed cavity and the water level change. This solves the problem of the ease of use of the float switch when it is placed at an angle, and enables the normal start and stop of the water pump and reduces costs.

AI Technical Summary

Technical Problem

When the water pump is not placed vertically, the existing float switch may cause the boom and float to move down unsmoothly due to insufficient weight, resulting in the water pump being unable to stop, which reduces its ease of use.

Method used

A partition plate is used to divide the float chamber into a sealed chamber and an open chamber. The sealed chamber stores gas to provide buoyancy, while the open chamber is connected to the outside. The weight of the float is adjusted by changes in water level to ensure that the float moves smoothly up and down.

Benefits of technology

This design improves the ease of use of the float structure, ensures that the water pump can start and stop normally, and reduces the cost of the float while keeping its size small.

Description

Technical Field

[0001] This application relates to the technical field of float switches, and in particular to a float structure with its own weight. Background Technology

[0002] Current float switches control the start and stop of water pumps by using the buoyancy of a float to trigger an inductive switch when the water level changes.

[0003] For example, Chinese Patent Application No. 2017113434337 discloses a float switch, including a base and an outer cover. A micro switch and a toggle lever are housed within the cavity of the outer cover. A boom is movably connected to the base, with a float fixed to the lower end of the boom and the upper end of the boom connected to the toggle lever. A magnet is fixed to the upper end of the boom, and another magnet is fixed to the other end of the toggle lever. The two magnets are positioned opposite each other. When the water level is high, the float rises and pushes the boom. When the two magnets attract each other, the toggle lever pushes the button of the micro switch, and the water pump starts working. When the water level drops, the float loses buoyancy, and the boom moves downwards under its own weight and the weight of the float. The two magnets move away from each other, the button of the micro switch is not triggered, and the water pump stops working.

[0004] Regarding the aforementioned technologies, the inventors discovered that water pumps are not necessarily placed completely vertically in the water. In particular, when the bottom of the water is uneven, there may be a certain tilt angle. If the weight of the boom and float is insufficient, the descent may be difficult, causing the water pump to be unable to stop, resulting in low ease of use. Therefore, there are certain areas for improvement. Utility Model Content

[0005] To improve ease of use, this application provides a float structure with its own weight.

[0006] The self-weighted float structure provided in this application adopts the following technical solution:

[0007] A self-weighted float structure includes a float body, a float cavity is provided inside the float body, a partition plate is provided inside the float cavity, the partition plate divides the float cavity into a sealed cavity and an open cavity, and a flow port connected to the open cavity is provided on the float body.

[0008] Preferably, the partition plate is horizontally arranged, dividing the float cavity into a sealed cavity and an open cavity. The sealed cavity and the open cavity are arranged vertically, with the sealed cavity located above the open cavity, and the flow port located on the side wall of the float body.

[0009] Preferably, multiple flow ports are provided along the circumferential direction of the float body.

[0010] Preferably, the partition plate is horizontally arranged, dividing the float cavity into a sealed cavity and an open cavity. The sealed cavity and the open cavity are arranged vertically, with the open cavity located above the sealed cavity. The flow port is located on the side wall of the float body or on the top of the float body.

[0011] Preferably, multiple flow ports are provided along the circumferential direction of the float body.

[0012] Preferably, the partition plate is arranged vertically, dividing the float cavity into a sealed cavity and an open cavity, the sealed cavity being located outside the open cavity, and the flow port being located at the top of the float body.

[0013] Preferably, the partition plate is arranged vertically, dividing the float cavity into a sealed cavity and an open cavity, the open cavity being located outside the sealed cavity, and the flow port being located at the top of the float body or on the side wall of the float body.

[0014] Preferably, the float body has a through-hole in the middle, and the sealing cavity and the opening cavity are arranged around the through-hole.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] In this application, the partition plate divides the float cavity into a sealed cavity and an open cavity. The sealed cavity generates buoyancy when sealed, while the open cavity communicates with the outside through a flow port, allowing outside water to enter. When the water level is high and the float needs to rise, since the open cavity is also filled with water, the weight of this water does not need to be considered; the buoyancy generated by the sealed cavity only needs to be greater than the float's own weight to achieve buoyancy. When the water level drops, there is still a large amount of water in the open cavity, which increases the weight of the float itself, thus facilitating its downward movement under its own weight. This float structure improves ease of use.

[0017] Furthermore, this application can ensure the required weight of the float structure while maintaining a small float structure volume, thereby reducing the cost of the float. Attached Figure Description

The sealed cavity 4 is located outside the open cavity 5, and the open cavity 5 is located inside the sealed cavity 4. Both the sealed cavity 4 and the open cavity 5 are arranged around the mounting port 2.

[0038] In this embodiment, the flow port 6 is located on the top of the float body 1. The flow port 6 can be one or more. When the flow port 6 is multiple, the flow port 6 is located along the circumferential direction of the float body 1.
