Description

Technical Field

[0001] This utility model relates to the field of liquid level switch technology, and in particular to a liquid level switch with an anti-corrosion coating. Background Technology

[0002] A liquid level switch, also known as a water level switch, is a switch that controls the on / off state of a circuit based on the liquid level. Liquid level switches are mainly divided into contact type and non-contact type. Commonly used non-contact switches include contact type, while contact type is the most widely used, such as electrode type liquid level switches.

[0003] In the prior art, such as Chinese Patent CN 219696328 U, a corrosion-resistant liquid level switch includes a liquid tank, a liquid level monitoring mechanism, and an alarm mechanism. A top cover is screwed to the top of the liquid tank, and a fixing rod is fixedly connected to the inner wall of the top cover. The liquid level monitoring mechanism is located on the inner wall of the liquid tank, and the alarm mechanism is located at the top of the liquid level monitoring mechanism. This corrosion-resistant liquid level switch, through its liquid level monitoring mechanism, allows for easy application during use. The anti-corrosion coating applied to the outside of the mounting column prevents corrosion of the mounting column when the liquid tank contains corrosive liquid, thus extending the service life of the liquid level switch. However, this patent also has the following problems.

[0004] In the aforementioned patent, although a sensing block and a float are incorporated, an alarm is triggered when the float touches the sensing block to prevent the liquid level in the tank from exceeding a set threshold. However, if the corrosive liquid in the tank contains impurities, these impurities may adhere to the surface of the float, altering its weight and buoyancy, thus affecting its normal rising and falling and accurate sensing of the liquid level. With prolonged use, the accumulation of impurities may also cause the float to become stuck, preventing it from moving properly with changes in the liquid level and rendering the liquid level monitoring function ineffective. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that if the corrosive liquid in the tank contains impurities, the accumulation of impurities after long-term use may cause the float to get stuck and fail to move normally with changes in liquid level, thus causing the liquid level monitoring function to fail. Therefore, this invention proposes an anti-corrosion coated liquid level switch.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a corrosion-resistant coating liquid level switch, including a top plate, a storage groove inside the top plate, a second gear rotatably mounted inside the storage groove, a motor fixedly mounted on the top of the top plate, the output end of the motor entering the storage groove and fixedly mounted on a first gear, the first gear meshing with the second gear, a rotating ring fixedly mounted on the bottom of the second gear, the bottom of the rotating ring penetrating the top plate and fixedly mounted on a filter frame, a mounting column fixedly mounted on the bottom of the top plate, a float slidably mounted on the outer wall of the mounting column, a bottom plate fixedly mounted on the outer wall of the mounting column, a rotating groove opening on the top of the bottom plate, a limiting ring fixedly mounted on the bottom of the filter frame, the limiting ring slidably connected to the rotating groove, and a scraper fixedly mounted on the bottom of the top plate.

[0007] Preferably, two limiting grooves are symmetrically opened at the bottom of the top plate. A spring is fixedly installed on the inner wall of the limiting groove. A limiting plate is fixedly installed at one end of the spring. A locking block and a pressure plate are fixedly installed on the outer wall of the limiting plate. One end of the pressure plate penetrates through the top plate.

[0009] Preferably, a sealing ring is fixedly installed at the bottom of the top plate, and a sealing groove is provided at the top of the water tank, with the sealing ring and the sealing groove being slidably connected.

[0010] Preferably, an inlet pipe is installed through and fixedly mounted on the outer wall of the water tank, and an outlet pipe is installed through and fixedly mounted on the bottom of the water tank, with a solenoid valve installed at the bottom of the outlet pipe.

[0011] Preferably, a sensing block and a placement ring are fixedly installed on the outer wall of the mounting column.

[0012] Preferably, a controller is fixedly installed on the top of the top plate, an alarm light is provided on the top of the controller, and an alarm is provided on the outer wall of the controller.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when in use, the liquid enters the water tank and comes into contact with the filter frame. After being filtered by the filter frame, the liquid enters the filter frame and pushes the float to rise. At this time, impurities remain on the outer wall of the filter frame. At the same time, the operator starts the motor. The output end of the motor drives the first gear to rotate, which in turn drives the second gear to rotate. The second gear drives the filter frame to rotate through the rotating ring. The outer wall of the filter frame comes into contact with the scraper, which can scrape off the impurities, thus improving the filtration efficiency and preventing impurities from adsorbing on the surface of the float.

[0015] 2. In this utility model, when installing the top plate, the worker presses down the pressure plate, which moves the locking blocks via the limiting plate, compressing the spring. Then, the worker inserts the two locking blocks into the two slots respectively. The worker then releases the pressure plate, and the spring force pushes the locking blocks into the slots, thus completing the installation and improving efficiency. Furthermore, the sealing ring enters the sealing groove at this time, improving the sealing performance. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figures 1-4As shown, this utility model provides a corrosion-resistant coating liquid level switch, including a top plate 1, a storage groove 13 inside the top plate 1, a second gear 16 rotatably mounted inside the storage groove 13, a motor 14 fixedly mounted on the top of the top plate 1, the output end of the motor 14 entering the storage groove 13 and a first gear 15 fixedly mounted thereon, the first gear 15 meshing with the second gear 16, a rotating ring 17 fixedly mounted on the bottom of the second gear 16, the bottom of the rotating ring 17 penetrating the top plate 1 and a filter frame 18 fixedly mounted thereon, a mounting post 19 fixedly mounted on the bottom of the top plate 1, a float ball 25 slidably mounted on the outer wall of the mounting post 19, a bottom plate 20 fixedly mounted on the outer wall of the mounting post 19, a rotating groove 21 opening on the top of the bottom plate 20, a limit ring 22 fixedly mounted on the bottom of the filter frame 18, the limit ring 22 slidably connected to the rotating groove 21, and a scraper 12 fixedly mounted on the bottom of the top plate 1.

[0024] The effect achieved by the entire embodiment 1 is as follows: when in use, the liquid enters the water tank 2 and comes into contact with the filter frame 18. After being filtered by the filter frame 18, the liquid enters the filter frame 18 and pushes the float 25 to rise. At this time, impurities remain on the outer wall of the filter frame 18. At the same time, the operator starts the motor 14. The output end of the motor 14 drives the first gear 15 to rotate, which in turn drives the second gear 16 to rotate. The second gear 16 drives the filter frame 18 to rotate through the rotating ring 17. The outer wall of the filter frame 18 comes into contact with the scraper 12, which can scrape away the impurities, thus improving the filtration efficiency and preventing impurities from adsorbing on the surface of the float 25.

[0025] Example 2, as Figures 1-4 As shown, further, two limiting grooves 28 are symmetrically opened at the bottom of the top plate 1. A spring 29 is fixedly installed on the inner wall of the limiting groove 28. A limiting plate 30 is fixedly installed at one end of the spring 29. A locking block 31 and a pressure plate 32 are fixedly installed on the outer wall of the limiting plate 30. One end of the pressure plate 32 penetrates through the top plate 1.

[0026] Furthermore, a water tank 2 is provided at the bottom of the top plate 1, and a connecting ring 3 is fixedly installed on the outer wall of the water tank 2. Two slots 26 are symmetrically opened on the top of the connecting ring 3, and a slot 27 is opened on the inner wall of the slot 26.

[0027] Furthermore, a sealing ring 11 is fixedly installed at the bottom of the top plate 1, and a sealing groove 10 is opened at the top of the water tank 2, with the sealing ring 11 and the sealing groove 10 slidably connected.

[0028] Furthermore, an inlet pipe 7 is installed through and fixedly mounted on the outer wall of the water tank 2, and an outlet pipe 8 is installed through and fixedly mounted on the bottom of the water tank 2. A solenoid valve 9 is installed at the bottom of the outlet pipe 8 to discharge the liquid in the water tank 2.

[0029] Furthermore, a sensing block 23 and a placement ring 24 are fixedly installed on the outer wall of the mounting column 19. The outer wall of the mounting column 19 is coated with an anti-corrosion coating. Through the anti-corrosion coating on the outside of the mounting column 19, when the water tank 2 is filled with corrosive liquid, the anti-corrosion coating can prevent the liquid from corroding the mounting column 19, thereby extending the service life of the liquid level switch.

[0030] Furthermore, a controller 4 is fixedly installed on the top of the top plate 1, an alarm light 5 is installed on the top of the controller 4, and an alarm 6 is installed on the outer wall of the controller 4.

[0031] The overall effect of Embodiment 2 is as follows: When installing the top plate 1, the worker presses down the pressure plate 32, which moves the locking blocks 31 via the limiting plate 30, compressing the spring 29. Then, the worker inserts the two locking blocks 31 into the two slots 26 respectively. The worker then releases the pressure plate 32, and the spring force of the spring 29 pushes the locking blocks 31 into the slots 27, thus completing the installation and improving installation efficiency. Furthermore, at this time, the sealing ring 11 enters the sealing groove 10, improving the sealing performance.

[0032] Working principle: During use, the operator introduces liquid into the inlet pipe 7, which then enters the water tank 2. The liquid comes into contact with the filter frame 18 and, after being filtered by the filter frame 18, enters the filter frame 18, pushing the float 25 upward. At this time, impurities remain on the outer wall of the filter frame 18. Simultaneously, the operator starts the motor 14. The output of the motor 14 drives the first gear 15 to rotate, which in turn drives the second gear 16 to rotate. The second gear 16 drives the filter frame 18 to rotate through the rotating ring 17. The outer wall of the filter frame 18 comes into contact with the scraper 12, which scrapes away the impurities, improving filtration efficiency and preventing impurities from adhering to the surface of the float 25. When the float 25 comes into contact with the sensing block 23, the alarm 6 sounds, and the alarm light 5 illuminates, alerting the operator. When installing the top plate 1, the worker presses down the pressure plate 32. The pressure plate 32 moves the locking block 31 through the limiting plate 30, compressing the spring 29. Then, the worker inserts the two locking blocks 31 into the two slots 26 respectively. The worker then releases the pressure plate 32, and the spring force of the spring 29 pushes the locking block 31 into the slot 27, thus completing the installation and improving installation efficiency. At this time, the sealing ring 11 enters the sealing groove 10, improving the sealing performance.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
