Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water level monitoring equipment, in particular to an automatic water filling device for a water tank based on a proximity switch. Background Art
[0002] Traditional automatic water replenishment devices mainly use a water level controller to detect the continuity between electrodes inserted into the water to obtain water level signals, thereby controlling the opening and closing of the solenoid valve to achieve automatic water replenishment. However, when the water is clean, the water will not be conductive, and the water level controller cannot obtain water level signals by detecting the continuity between the electrodes inserted into the water. When the water quality is poor, although the water level controller can obtain water level signals by detecting the continuity between the electrodes, impurities in the dirty water can easily adhere to the surface of the electrodes, changing the conductivity of the electrodes, causing distortion of the water level detection results, and easily leading to water shortages or flooding accidents. Water replenishment can also be done through manual observation. However, because this link takes a long time, it is very easy to forget to refill the water tank on time, causing the water level in the tank to be lower than the environmental water level requirement for a long time. Utility Model Content
[0003] In order to solve the technical problems mentioned in the background technology, the utility model provides an automatic water tank water replenishing device based on a proximity switch.
[0004] The utility model adopts the following technical solution: an automatic water filling device for a water tank based on a proximity switch, comprising a sliding rod; the sliding rod is arranged in the water tank through a fixed bracket; a metal float is slidably connected to the sliding rod; a conical protrusion is arranged at the bottom of the sliding rod to prevent the metal float from sliding out of the sliding rod; a switch group connecting bracket is arranged at the top of the sliding rod; a low water level proximity switch, a water filling level proximity switch, a water stop level proximity switch and a high water level proximity switch for marking the water level are arranged on the connecting bracket in sequence from bottom to top; the low water level proximity switch, the water filling level proximity switch, the water stop level proximity switch and the high water level proximity switch are connected in sequence to a water level controller arranged on the outside of the water tank; the water level controller is connected to a first solenoid valve arranged on the water supply pipeline, for controlling the water supply pipeline to fill water into the water tank.
[0005] Furthermore, the water level controller is connected to an audible and visual alarm device.
[0006] Furthermore, a filter is provided at the junction of the water supply pipeline and the water tank.
[0007] Furthermore, the bottom of the water tank is connected to a drain pipe; a second solenoid valve is provided on the drain pipe, and when the high water level proximity switch is turned on, the second solenoid valve controls the drain pipe to discharge water out of the water tank.
[0008] Compared with the prior art, the advantages of the present invention are:
[0009] The automatic water replenishing device for water tank based on proximity switches involved in the present utility model has a positive correlation between the height of the metal float ball and the water level in the water tank. The float ball and the proximity switch group cooperate to form a control unit for the electromagnetic valve of the water supply pipeline to realize the on-off of the water supply line. When the water level in the water tank is at a low level, the water supply line is turned on to replenish water to the water tank, and when the water tank is at a high level, the water supply line is cut off to stop replenishing water to the test pool. At the same time, the drain pipe drains water in time to lower the water level in the water tank to a safe height.

Detailed Embodiments
[0013] Hereinafter, for the convenience of those skilled in the art to understand the technical solution of the present utility model, further description will be made with reference to the drawings. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model.
[0014] In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present utility model. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0015] Please refer to Figure 1, which is the overall structural schematic diagram of the automatic water replenishing device for the water tank based on the proximity switch of the present utility model, includes a sliding rod 1. The sliding rod 1 is arranged in the water tank 3 through a fixed bracket 2. A metal floating ball 4 is slidably connected to the sliding rod 1. A conical protrusion 5 is arranged at the bottom of the sliding rod 1 to prevent the metal floating ball 4 from sliding out of the sliding rod 1. A switch group connection bracket 6 is arranged at the top of the sliding rod 1. A low water level proximity switch 7 for marking the water level, a water injection water level proximity switch 8, a stop water level proximity switch 9, and a high water level proximity switch 10 are sequentially arranged on the switch group connection bracket 6 from bottom to top. The low water level proximity switch 7, the water injection water level proximity switch 8, the stop water level proximity switch 9, and the high water level proximity switch 10 are sequentially connected to a water level controller 11 arranged outside the water tank. The water level controller 11 is connected to a first electromagnetic valve 13 arranged on the water supply pipeline 12 for controlling the water supply pipeline 12 to inject water into the water tank 3. A filter screen 15 is arranged at the junction of the water supply pipeline 12 and the water tank 3 for filtering impurities in the water supply. The water level controller 11 is connected to an audible and visual alarm device 14.
[0016] In addition, the bottom of the water tank 3 is connected to a drain pipe 16. A second electromagnetic valve 17 is arranged on the drain pipe 16. When the high water level proximity switch 10 is turned on, the second electromagnetic valve 17 controls the drain pipe 16 to discharge water outside the water tank 3 so that the water level approaches the height of the stop water level proximity switch 9.
[0017] In the specific implementation of this embodiment, appropriate water levels are set by adjusting the positions of the low water level proximity switch 7, the water injection water level proximity switch 8, the stop water level proximity switch 9, and the high water level proximity switch 10 according to requirements. After the positions of the proximity switches are adjusted, due to the buoyancy of water, the metal floating ball 4 moves up and down in the water tank along the cylindrical sliding rod 1 with the water level. When the water level in the water tank drops to the water injection water level, the hollow metal floating ball 2 drops to the water injection water level proximity switch 8, and the water level controller 11 turns on the first electromagnetic valve 13 to replenish water into the water tank. The hollow metal floating ball 2 rises continuously with the water level in the water tank. When the hollow metal floating ball 2 rises to the stop water proximity switch 9, the water level controller 7 closes the electromagnetic valve 8 to stop injecting water into the water tank.
[0018] When the water level in the water tank drops to the low water level proximity switch 7 or rises to the high water level proximity switch 9, the hollow metal floating ball 2 will turn on the low water level proximity switch 7 or the high water level proximity switch 10. The water level controller 7 drives the audible and visual alarm device 14 to emit audible and visual alarms to remind the staff that the water level in the water tank is abnormal. At the same time, when the water level is at a high level, the water level controller 11 also controls the second electromagnetic valve 17 to start, and discharges water urgently outside through the drain pipe 16 to prevent water from overflowing from the water tank 3 and causing accidents.
[0019] In summary, the automatic water replenishing device for water tanks based on proximity switches according to the present utility model has a metal floating ball whose height is positively correlated with the water level in the water tank. The floating ball and the proximity switch group cooperate to form a control unit for the solenoid valve controlling the water supply pipeline, so as to realize the on-off of the water supply line. When the water level in the water tank is at a low level, the water supply line is turned on to replenish water to the water tank, and when the water tank is at a high level, the water supply line is cut off to stop replenishing water to the test pool. At the same time, the drain pipe drains water in time to lower the water level in the water tank to a safe height. This device is safe and reliable, not affected by water quality and water conductivity during use, can accurately replenish water to the water tank and can give an alarm in time when the water level is abnormal.
[0020] The above embodiments are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solution of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
