Description
Technical Field
[0001] This utility model relates to the field of float switch technology, and in particular to an insertable sheathed float switch. Background Technology
[0002] In industrial production, liquid level control, and various automation systems, accurate and reliable liquid level monitoring and control are crucial. Submersible sheathed float switches, as a commonly used liquid level detection device, have a wide range of applications in many fields, from traditional industrial water tanks and pools to domestic sewage treatment and aquaculture. As various industries continue to increase their requirements for automation and production efficiency, higher expectations are being placed on the performance and stability of submersible sheathed float switches.
[0003] In existing liquid level detection technologies, many mechanical liquid level switches use the principle of simple float and mechanical lever linkage. When the liquid level changes, the float rises and falls accordingly, triggering a micro switch through the lever mechanism, thereby realizing the detection of liquid level and signal transmission. This structure is simple and direct, and the cost is relatively low. It has been widely used in some scenarios where the requirements for accuracy and stability are not high.
[0004] However, traditional submersible sheathed float switches generally have a problem: they cannot flexibly adapt to liquid environments with different densities. Since the buoyancy and overall weight of the float are fixed, when faced with liquids with large density differences, the float is difficult to accurately trigger the switch action at the appropriate liquid level, resulting in inaccurate liquid level detection and seriously affecting its application in diverse industrial scenarios. To address this issue, a new submersible sheathed float switch is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an immersion-type sheathed float switch, which aims to improve the problem that the existing immersion-type sheathed float switch cannot flexibly adapt to liquid environments of different densities, resulting in inaccurate liquid level detection.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A submersible sheathed line float switch includes a control assembly, one end of which is provided with a float, and the outer wall of the float is provided with an adjustment component, which is used to adjust the counterweight of the float;
[0008] The adjustment assembly includes a counterweight box, which is slidably connected to the outer wall of the float. A connecting plate is fixedly connected inside the counterweight box. A support shaft is fixedly connected to the top of the connecting plate, and a connecting plate is fixedly connected to the top of the support shaft. A support plate is fixedly connected to the top of the connecting plate, and a sliding shaft is fixedly connected to the bottom of the connecting plate. A connecting shaft is slidably connected to the inner wall of the sliding shaft, and the top of the connecting shaft is fixedly connected to the top of the connecting plate. A spring is provided on the outer wall of the connecting shaft, with one end fixedly connected to the outer wall of the sliding shaft and the other end fixedly connected to the outer wall of the connecting shaft. A disassembly assembly is provided on the outer wall of the counterweight box for disassembling the counterweight box.
[0009] As a further description of the above technical solution:
[0010] The disassembly assembly includes a first connecting block and a second connecting block. The first connecting block is fixedly connected to the outer wall of the counterweight box, and the second connecting block is fixedly connected to the outer wall of the float.
[0011] As a further description of the above technical solution:
[0012] The connecting block has a fixed column inside, and the fixed column has a transmission rod threaded inside.
[0013] As a further description of the above technical solution:
[0014] A rotating handle is fixedly connected to the top of the transmission rod, and a slot is provided inside the second connecting block.
[0015] As a further description of the above technical solution:
[0016] A mounting column is fixedly connected to the bottom end of the fixed column, and a connecting plate is fixedly connected to the bottom of the transmission rod.
[0017] As a further description of the above technical solution:
[0018] A conical block is fixedly connected to the bottom of the connecting plate, and a limiting ball is slidably connected inside the mounting column.
[0019] As a further description of the above technical solution:
[0020] The limiting ball contacts the outer wall of the conical block, and the limiting ball fits into the slot.
[0021] As a further description of the above technical solution:
[0022] The bottom of the conical block is fixedly connected to a base, which slides on the inner wall of the mounting column.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, by placing the counterweight block inside the counterweight box, the support shaft is squeezed and elastically deformed, which further causes the connecting shaft to slide inside the sliding shaft, causing the spring to elastically deform, thereby achieving the effect of quickly increasing the counterweight of the equipment. This solves the problem that traditional submersible sheathed float switches cannot flexibly adjust the counterweight and are difficult to accurately trigger liquid level detection in liquids of different densities, thus improving the application efficiency of liquid level detection equipment in diverse working scenarios.
[0025] 2. In this utility model, by rotating the handle, the transmission rod rotates inside the fixed column, thereby interfering with and driving the installation column to move. Under the movement of the conical block, the limit ball and the slot cooperate to achieve the effect of quick disassembly and installation of the counterweight box. This solves the problem that the traditional submersible sheathed float switch is cumbersome to install and disassemble when maintaining or adjusting the counterweight, which consumes a lot of time and manpower. This improves the efficiency of equipment maintenance and debugging. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0034] Reference Figure 1 - Figure 4 The present invention provides an embodiment of an insertable sheathed line float switch, comprising a control assembly 1, a float 2 disposed at one end of the control assembly 1, and an adjustment component disposed on the outer wall of the float 2, the adjustment component being used to adjust the counterweight of the float 2;
[0035] The adjustment assembly includes a counterweight box 3, which is slidably connected to the outer wall of the float 2 to add counterweights for easy adjustment by the user. A connecting plate 4 is fixedly connected inside the counterweight box 3, and a support shaft 5 is fixedly connected to the top of the connecting plate 4 to provide buffering force and ensure stability. A connecting plate 9 is fixedly connected to the top of the support shaft 5, and a support plate 10 is fixedly connected to the top of the connecting plate 9 to provide a certain support force and further transmit the force. A sliding shaft 7 is fixedly connected to the bottom of the connecting plate 9, and a connecting shaft 6 is slidably connected to the inner wall of the sliding shaft 7. The top of the connecting shaft 6 is fixedly connected to the top of the connecting plate 4. A spring 8 is provided on the outer wall of the connecting shaft 6 to provide a certain elastic restoring force and maintain the stability of the float 2. One end of the spring 8 is fixedly connected to the outer wall of the sliding shaft 7, and the other end is fixedly connected to the outer wall of the connecting shaft 6. A disassembly assembly is provided on the outer wall of the counterweight box 3 for disassembling the counterweight box 3.
[0036] Specifically, when the submersible sheathed float switch is used in environments where the density of the liquid is lower than that of conventionally detected liquids, or when more precise control of the liquid level is required and interference from liquid fluctuations is needed, the operator can place a counterweight inside the counterweight box 3. When the counterweight enters the counterweight box 3, it generates a compressive force, which pushes the support plate 10. The support plate 10 transmits this compressive force to the support shaft 5, forcing the support shaft 5 to move elastically. The elastic movement of the support shaft 5 will drive the sliding shaft 7 on the connecting shaft 6 to slide on its outer wall. The movement of the sliding shaft 7 further forces the spring 8 to undergo elastic deformation, thereby protecting the float 2 and the counterweight box 3. This ensures that the counterweight of the float 2 can be effectively adjusted under different liquid conditions, while avoiding damage to other components. It also facilitates the operator's adjustment of the counterweight of the float 2, ensuring that the device adapts to the usage requirements of different liquids.
[0037] Reference Figure 3 and Figure 5The disassembly assembly includes connecting block 11 and connecting block 2 12. Connecting block 11 is fixedly connected to the outer wall of the counterweight box 3 to provide a stable connection and support. Connecting block 2 12 is fixedly connected to the outer wall of the float 2. The fixed connection ensures the stability of the assembly's movement. A fixing column 13 is fixedly connected inside the connecting block 11. A transmission rod 14 is threadedly connected inside the fixing column 13. A rotating handle 15 is fixedly connected to the top of the transmission rod 14 to facilitate the operator's drive of the assembly's movement. A slot 17 is opened inside the connecting block 2 12. A mounting column 16 is fixedly connected to the bottom of the fixing column 13. A connecting plate 18 is fixedly connected to the bottom of the transmission rod 14.
[0038] Specifically, when the float switch of the submersible sheathed line needs to be regularly maintained and inspected for the condition of the counterweight, the counterweight needs to be frequently adjusted according to the liquid level control requirements, and the faulty parts in the counterweight box 3 need to be quickly replaced due to equipment failure, the operator can disassemble it by turning the rotating handle 15. When the handle 15 is turned, the rotational force is transmitted through the transmission rod 14, causing the transmission rod 14 to rotate within the fixed column 13.
[0039] Reference Figure 3 and Figure 5 A conical block 19 is fixedly connected to the bottom of the connecting plate 18 to transmit power and drive the limiting ball 20 to cooperate with the slot 17. The limiting ball 20 is slidably connected inside the mounting column 16. The limiting ball 20 contacts the outer wall of the conical block 19 to ensure that it can be squeezed by the conical block 19. The limiting ball 20 fits into the slot 17 to achieve quick fixing and unlocking. A base 21 is fixedly connected to the bottom of the conical block 19 and slides on the inner wall of the mounting column 16.
[0040] Specifically, the connecting plate 18 and the conical block 19 move inside the mounting column 16. The movement of the conical block 19 forces the limiting ball 20 to slide along the outer wall, eventually locking the limiting ball 20 into the slot 17, achieving the effect of quick fixing and unlocking. This greatly improves the convenience and efficiency of disassembly, allowing operators to quickly adjust the equipment according to actual needs, ensuring the functionality of the equipment, and providing great convenience and flexibility during operation.
[0041] Working principle: When using this switch, the control assembly 1 is switched on and off via the float 2. When it is necessary to add counterweight to the float 2, the operator places the counterweight block into the counterweight box 3. When the counterweight block is placed into the counterweight box 3, it will generate a compressive force. The other part of the force is transmitted to the support shaft 5 through the support plate 10, causing the support shaft 5 to move elastically. At the same time, the sliding shaft 7 slides on the outer wall of the connecting shaft 6. The sliding of the sliding shaft 7 forces the spring 8 to deform elastically, thereby protecting the counterweight box 3 and the float 2, and facilitating the operator to adjust the counterweight of the float 2. It is suitable for use with different liquids. When it is necessary to disassemble the counterweight box 3, the rotating handle 15 is turned. Under the action of rotation, the transmission rod 14 rotates inside the fixed column 13, which further causes the connecting plate 18 and the conical block 19 to move inside the mounting column 16. When the conical block 19 moves, it forces the limiting ball 20 to slide on its outer wall, thereby locking into the slot 17 to achieve quick fixing and unlocking. This allows the operator to adjust the equipment according to the actual situation and ensures the functionality of the equipment.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
