Description

Technical Field

[0001] This utility model relates to the field of liquid level magnetic float switch technology, specifically a liquid level magnetic float switch. Background Technology

[0002] In many fields such as industrial production, chemical industry, petroleum, power, water treatment, and food industry, accurate detection and control of liquid level is crucial. For example, in equipment such as storage tanks, reactors, and water tanks, excessively high or low liquid levels may lead to abnormalities in the production process or even safety accidents. Therefore, a reliable and stable liquid level detection device is needed to monitor liquid level changes in real time and control them as needed.

[0003] In existing technology, this device monitors the liquid level by placing a magnet inside the float and changing the high and low liquid level points as the float moves up and down with the liquid surface. The internal magnetic sensitive element emits an on / off signal in a preset state. However, in actual use, the high and low liquid level points of this device are fixed, and the connecting rod is also fixed. Therefore, it is impossible to adjust the appropriate high and low liquid level points according to different liquid level requirements in the pipe. This limits the adaptability of the device and makes it unable to meet the height requirements of different scenarios. Therefore, it is necessary to improve the liquid level magnetic float switch. Utility Model Content

[0004] The purpose of this invention is to provide a liquid level magnetic float switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid level magnetic float switch, including a connecting base, a fixing hole inside the connecting base, an isolation mechanism at the top of the connecting base, an adjustment and monitoring mechanism at the bottom of the connecting base, and a switch outside the adjustment and monitoring mechanism;

[0006] The adjustment and monitoring mechanism includes an adjustment component and a monitoring component, wherein the monitoring component is disposed at the bottom of the adjustment component;

[0007] The adjustment assembly includes a locking pin, which is fixedly connected inside the connecting seat. A floating sleeve is slidably connected to the outside of the locking pin, and a fixed sleeve is fixedly connected to the outside of the floating sleeve. A push block is rotatably connected to the front of the fixed sleeve, and a rotating rod is fixedly connected to the back of the push block. Pull rods are rotatably connected to both ends of the rotating rod, and a locking block is rotatably connected to the end of the pull rod away from the rotating rod. A spring is fixedly connected between the locking block and the fixed sleeve, which facilitates the adjustment of the appropriate high and low liquid level positions according to different conditions inside the tank.

[0008] Preferably, the floating sleeve and the locking post are respectively provided with slots at positions corresponding to the locking block, and the locking block is inserted into the slots to facilitate fixing the position of the floating sleeve.

[0009] Preferably, a groove is provided at the position corresponding to the fixing sleeve and the card block, and the card block is slidably connected to the groove to facilitate limiting the position of the card block.

[0010] Preferably, the monitoring component includes a high liquid level point, which is fixedly connected inside the floating sleeve, a low liquid level point is fixedly connected inside the floating sleeve, and a floating ball is slidably connected outside the floating sleeve, so as to facilitate monitoring the liquid level inside.

[0011] Preferably, a groove is provided at the position corresponding to the floating ball of the floating sleeve, and the floating ball is slidably connected to the outside of the floating sleeve to facilitate restricting the movement of the floating ball.

[0012] Preferably, the isolation mechanism includes an isolation sleeve, which is inserted into the top of the connecting seat. A positioning block is fixedly connected to the left side of the isolation sleeve, and a connecting block is slidably connected inside the connecting seat. A spring is fixedly connected between the connecting block and the connecting seat to facilitate dust prevention and subsequent maintenance.

[0013] Preferably, the positioning block is inserted into the connector, and the isolation sleeve has a groove at the corresponding position of the connecting block, and the connecting block is inserted into the groove to facilitate fixing the position of the isolation sleeve.

[0014] Compared with the prior art, this utility model provides a liquid level magnetic float switch, which has the following beneficial effects:

[0015] 1. This liquid level magnetic float switch, through its adjustable monitoring mechanism, allows manual rotation of the push block before installation. As the pull rod moves outward, it pushes the two side locking blocks outward, completely disengaging them from the locking posts. Then, the fixed sleeve and floating sleeve move upward or downward. When the switch reaches the appropriate height, releasing the push block allows the locking blocks to re-insert under the force of the spring. This completes the position adjustment and fixation between the high and low points, further expanding the device's application range and adapting it to different height requirements.

[0016] 2. This liquid level magnetic float switch, through the set isolation mechanism, allows the connecting block to be completely separated from the isolation sleeve by manually pulling the connecting block to the right, and then pulling the isolation sleeve upward to complete the separation between the connecting seat and the isolation sleeve, thus facilitating inspection and maintenance by the staff.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Example 1:

[0028] Based on the existing technology, this device has fixed high and low liquid levels, and the connecting rod is also fixed. Therefore, it cannot adjust the high and low liquid levels according to different liquid level requirements in the pipe, resulting in a limited range of applicability. Please refer to [link to relevant documentation]. Figure 1-6 This utility model provides a technical solution: a liquid level magnetic float switch, including a connecting base 1, a fixing hole 2 inside the connecting base 1, an isolation mechanism 3 on the top of the connecting base 1, an adjustment monitoring mechanism 4 on the bottom of the connecting base 1, and a switch 5 on the outside of the adjustment monitoring mechanism 4;

[0029] The adjustment and monitoring mechanism 4 includes an adjustment component 41 and a monitoring component 42, with the monitoring component 42 located at the bottom of the adjustment component 41;

[0030] The adjusting assembly 41 includes a locking post 417, which is fixedly connected inside the connecting seat 1. A floating sleeve 421 is slidably connected to the outside of the locking post 417. A fixed sleeve 411 is fixedly connected to the outside of the floating sleeve 421. A push block 412 is rotatably connected to the front of the fixed sleeve 411. A rotating rod 413 is fixedly connected to the back of the push block 412. A pull rod 414 is rotatably connected to both ends of the rotating rod 413. A locking block 415 is rotatably connected to the end of the pull rod 414 away from the rotating rod 413. A spring 416 is fixedly connected between the locking block 415 and the fixed sleeve 411, which facilitates the adjustment of the appropriate high liquid level 422 and low liquid level 423 positions according to different conditions inside the tank.

[0031] Furthermore, the floating sleeve 421 and the locking post 417 are respectively provided with slots at the corresponding positions of the locking block 415, and the locking block 415 is inserted into the slots to facilitate fixing the position of the floating sleeve 421.

[0032] Furthermore, a groove is provided at the corresponding position of the fixing sleeve 411 and the locking block 415, and the locking block 415 slides into the groove to facilitate limiting the position of the locking block 415.

[0033] Furthermore, the monitoring component 42 includes a high liquid level point 422, which is fixedly connected inside the floating sleeve 421. A low liquid level point 423 is fixedly connected inside the floating sleeve 421, and a floating ball 424 is slidably connected outside the floating sleeve 421 to facilitate monitoring of the internal liquid level.

[0034] Furthermore, grooves are provided at the corresponding positions of the floating sleeve 421 and the floating ball 424, and the floating ball 424 is slidably connected to the outside of the floating sleeve 421, which facilitates restricting the movement of the floating ball 424.

[0035] Example 2:

[0036] Given the existing technology's need for dust protection and isolation, please refer to [link / reference]. Figure 6 Furthermore, in conjunction with Embodiment 1, it is further found that the isolation mechanism 3 includes an isolation sleeve 31, which is inserted into the top of the connecting seat 1. A positioning block 32 is fixedly connected to the left side of the isolation sleeve 31. A connecting block 33 is slidably connected inside the connecting seat 1. A spring 34 is fixedly connected between the connecting block 33 and the connecting seat 1 to facilitate dust prevention and subsequent maintenance.

[0037] Furthermore, the positioning block 32 is inserted into the connector 1, and the isolation sleeve 31 and the connector 33 are provided with grooves at corresponding positions, and the connector 33 is inserted into the grooves to facilitate fixing the position of the isolation sleeve 31.

[0038] In actual operation, when the device is used, firstly, fix the connecting seat 1 to the designated position using external fixing bolts. Before installation, manually rotate the push block 412 via the adjustable monitoring mechanism 4. This push block 412 drives the rotating rod 413 to rotate, which in turn pushes the pull rods 414 on both sides outwards. During this outward movement, the pull rods 414 push the locking blocks 415 on both sides outwards, completely disengaging them from the locking post 417. Then, move the fixing sleeve 411 and floating sleeve 421 upwards or downwards. When the device reaches the appropriate height, release the push block 412, allowing the locking block 415 to re-insert under the elastic force of the spring 416, into the groove corresponding to the locking post 417, thus completing the positioning between the high and low points. Adjustment and fixation further expand the application range of the device, making it adaptable to the needs of different scene heights. Then, the entire device is fixed in the designated position. When it starts working, magnetic sensitive elements are set inside the high liquid level 422 and the low liquid level 423. When the floating ball 424 moves up and down with the liquid level to the high liquid level 422 and the low liquid level, it changes the preset state of the internal magnetic sensitive element, thereby sending an on / off signal, which is received by the control system to monitor the liquid level. When it is necessary to repair the components inside the fixed sleeve 411 later, the connecting block 33 is completely separated from the isolation sleeve 31 by manually pulling the connecting block 33 to the right through the isolation mechanism 3. Then, the isolation sleeve 31 is pulled up to complete the separation between the connecting seat 1 and the isolation sleeve 31.
