Description

Technical Field

[0001] This utility model belongs to the field of water immersion sensor technology, and specifically relates to a water immersion sensor. Background Technology

[0002] Traditional immersion sensors require changing the length of the cable according to the monitoring distance when adjusting the monitoring distance, which leads to complex inventory management and increased costs. If long cables are used directly, the excess part needs to be fixed with cable ties, which requires repeated untying and binding during adjustment, resulting in low efficiency. Moreover, the cable ties are prone to loosening, the cables are prone to tangling, and after long-term use, the cable ties are prone to aging and breakage. Exposed redundant cables are susceptible to external pulling, mechanical damage, or environmental corrosion, affecting the sensor's lifespan and monitoring accuracy. Therefore, there is an urgent need for a immersion sensor that can properly fix and store redundant cables. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a water immersion sensor, which features easy wiring fixation and storage, and good storage performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a water immersion sensor, comprising a sensor body and a first monitoring line and a second monitoring line connected to the bottom of the sensor body. The ends of the first monitoring line and the second monitoring line are electrically connected to monitoring probes for monitoring external water immersion conditions. A storage cylinder is provided below the sensor body, and the storage cylinder is fixed to an external building through an end mounting plate. An internally threaded cylinder is provided in the middle of the inner side of the storage cylinder, and the end of the internally threaded cylinder is fixedly connected to the mounting plate. The second monitoring line is wound around the outside of the internally threaded cylinder. A compression assembly is provided at the end of the storage cylinder. The compression assembly includes a rotating plate, a screw, a connecting cylinder, and a compression ring. The screw is fixed in the middle of the side wall of the rotating plate, and the screw is fixed in the middle of the rotating plate and threadedly connected to the internally threaded cylinder. The connecting cylinder is fixed to the edge of the rotating plate and its end is connected to the compression ring. The compression ring is located between the internally threaded cylinder and the storage cylinder to compress the second monitoring line.

[0005] As a preferred technical solution of the immersion sensor of this utility model, the top surface of the storage tube is provided with an upper wire outlet, the bottom surface of the storage tube is provided with a lower wire outlet, and the second monitoring line passes through the upper wire outlet and the lower wire outlet in sequence.

[0006] As a preferred technical solution of the immersion sensor of this utility model, the side wall of the compression ring is fixed with a soft washer. The soft washer is made of silicone or rubber and is used to elastically compress the second monitoring line and prevent the line from wearing.

[0007] As a preferred technical solution of the immersion sensor of this utility model, the outer ring of the rotating plate is provided with multiple grooves for manually rotating the screw.

[0008] As a preferred technical solution of the immersion sensor of this utility model, the outer ring size of the rotating plate is adapted to the outer ring size of the storage tube.

[0009] As a preferred technical solution of the immersion sensor of this utility model, the annular distance between the inner threaded cylinder and the inner wall of the storage cylinder is equal to the radial thickness of the extrusion ring, so that the extrusion ring can be tightly embedded and press the circuit.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This solution uses a storage cylinder, an internally threaded cylinder, and a compression assembly to fix the storage cylinder below the sensor. The monitoring line at the bottom of the sensor is wound around the outside of the internally threaded cylinder in the middle of the storage cylinder. Simultaneously, one side of the compression assembly is threadedly connected to the internally threaded cylinder. Rotating the rotating plate of the compression assembly allows the screw of the compression assembly to move inside the internally threaded cylinder, causing the compression ring on the edge of the rotating plate to move between the storage cylinder and the internally threaded cylinder. This achieves compression and positioning of the wound monitoring line, ensuring stability and preventing the line from loosening. The screw can be turned to adjust the degree of compression on the line, allowing for flexible adjustment based on the length of the wound line. It maintains a stable compression state for different winding lengths of line. When adjusting the line length later, reversing the screw removes the compression ring, allowing for direct pulling to extend the line. The solution is easy to operate, simple in structure, not easily damaged during long-term use, and has a long service life. Furthermore, the storage cylinder protects the wound line from external mechanical damage, resulting in excellent storage performance. Attached Figure Description

[0018] 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.

[0019] The present invention proposes the following technical solution, with reference to... Figure 1 As shown, specifically, a water immersion sensor includes a sensor body 1 and a first monitoring line 2 and a second monitoring line 3 connected to the bottom of the sensor body 1. The ends of the first monitoring line 2 and the second monitoring line 3 are electrically connected to a monitoring probe 4 for monitoring external water immersion conditions. The sensor body 1 is fixed to a designated area by screws, and its monitoring lines and probes are placed in the monitoring area. When the monitoring area is immersed in water, it can be monitored through the probes. The specific structure and operating principle of the above-mentioned water immersion sensor can be referred to the existing technology, so they are not described in detail here.

[0020] Reference Figure 2 and Figure 3As shown, specifically, a storage cylinder 5 is provided below the sensor body 1. The storage cylinder 5 is fixed to the external building via a mounting plate 54 at its end. The mounting plate 54 has through holes on its side, allowing it to be fixed to the external building with screws. An internally threaded cylinder 51 is provided in the middle of the inner side of the storage cylinder 5. The internally threaded cylinder 51 is parallel to the storage cylinder 5, and its end is fixedly connected to the mounting plate 54. The second monitoring line 3 is wound around the outside of the internally threaded cylinder 51. The top surface of the storage cylinder 5 has an upper cable outlet 52, and the bottom surface of the storage cylinder 5 has a lower cable outlet 53. The second monitoring line 3 passes through the upper cable outlet 52 and the lower cable outlet 53 in sequence. A pressing assembly 6 is provided at the end of the storage cylinder 5. The pressing assembly 6 includes a rotating plate 61, a screw 62, and a connecting cylinder 6. 3. The outer ring size of the rotating plate 61 is adapted to the outer ring size of the storage cylinder 5. The middle of the side wall of the rotating plate 61 is fixed with a screw 62. The screw 62 is fixed in the middle of the rotating plate 61 and threadedly connected to the inner thread cylinder 51. The storage cylinder 5 and the inner thread cylinder 51 are integrally formed plastic or metal parts, and the thread length of the inner thread cylinder 51 is greater than the thread length of the screw 62 to achieve multi-stage stroke adjustment. The connecting cylinder 63 is fixed to the side of the rotating plate 61 and the end is connected to the extrusion ring 64. The extrusion ring 64 is located between the inner thread cylinder 51 and the storage cylinder 5 to extrude the second monitoring line 3. The annular distance between the inner thread cylinder 51 and the inner wall of the storage cylinder 5 is equal to the radial thickness of the extrusion ring 64, so that the extrusion ring 64 can be tightly embedded and press the line.

[0021] Specifically, using the above technical solution, when using the immersion sensor, the operator places the monitoring probe 4 in the designated position. Then, the redundant wires can be passed through the outlet of the storage cylinder 5 and wound around the outside of the inner threaded cylinder 51 inside the storage cylinder 5 until the redundant wires are fully stored. The operator then connects the screw 62 of the extrusion assembly 6 to the inner threaded cylinder 51 and rotates the screw 62 through the rotating plate 61 to move it inside the threaded cylinder. This allows the extrusion ring 64 on the side of the rotating plate 61 to be embedded between the storage cylinder 5 and the inner threaded cylinder 51, achieving extrusion and positioning of the inner wound wires. Compared with the traditional method of binding and fixing with cable ties, the positioning is more stable and less prone to loosening. Furthermore, when adjusting the wire length later, the extrusion ring 64 can be easily rotated and removed. The overall tool structure has high strength, avoiding the situation where cable ties are easily broken and damaged when repeatedly bound. In addition, the storage cylinder can properly protect the wound wires from external mechanical damage, making it highly practical.

[0022] Reference Figure 4 As shown, specifically, the side wall of the compression ring 64 is fixed with a soft washer 641. The soft washer 641 is made of silicone or rubber and is used to elastically compress the second monitoring line 3 and prevent line wear. The rotation direction of the rotating plate 61 and the compression ring 64 is the same as the winding direction of the line to avoid the line being scraped and loosened when the line is compressed.

[0023] Reference Figure 3 and Figure 4 As shown, specifically, the outer ring of the rotating plate 61 is provided with multiple grooves 611 for manually rotating the screw 62, so that the operator can perform circuit adjustment without the need for additional tools, making the operation convenient.

[0024] The working principle and usage process of this utility model are as follows: When using the immersion sensor, the operator fixes the sensor in place, and then fixes the storage cylinder 5 below the sensor body 1 through the mounting plate 54. The operator then connects the end of the monitoring line to the sensor body 1 and places the monitoring probe 4 at the end of the monitoring line in the monitoring position. The operator then passes the redundant monitoring line through the outlet on the protective cylinder 5 and winds the monitoring line around the outside of the inner threaded cylinder 51 inside the storage cylinder 5 to store the redundant line. After storing the excess line, the operator aligns the screw 62 of the extrusion assembly 6 with the inner threaded cylinder 51 and aligns the extrusion ring 64 with the storage cylinder 5. The operator rotates the screw 62 to move it inside the inner threaded cylinder 51, thereby moving the extrusion ring 64 inside the storage cylinder 5 to extrude and position the wound line, facilitating proper storage and protection of the line. When the monitoring position needs to be adjusted and the line length needs to be readjusted, the extrusion assembly 6 can be rotated and removed, and then the line can be pulled or rewound. The operation is convenient.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
