Description

Technical Field

[0001] This utility model relates to the field of water environment detection technology, specifically a probe for a water environment detection sensor. Background Technology

[0002] In the field of water environment monitoring, the probe, as the core component of the sensor, directly affects the detection accuracy and reliability. The probe can detect water quality in the water environment, thereby providing data support for the specific conditions of the water quality. However, due to insufficient protection of the existing sensor probes during use, the probe head is prone to wear, which leads to unstable data in subsequent water quality monitoring and affects the accuracy of the data detection.

[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN209841221U, published on 2019-12-24) provides a probe for a thermistor, belonging to the field of temperature sensor technology. It includes a heat-conducting sleeve, with a sliding sleeve fitted inside the open end of the sleeve. The sliding sleeve and the heat-conducting sleeve communicate to form an open cavity. Within this cavity, from the bottom plate of the heat-conducting sleeve to the open end, a thermal expansion element, a first column, and a second column are sequentially arranged. The surface of the heat-conducting sleeve is provided with heat-conducting fins. This increases the probe's thermal conductivity and conduction performance, and provides wear-resistant protection using appropriate materials, thereby improving the probe's sensitivity and service life.

[0004] The aforementioned mechanisms improve the sensitivity and lifespan of the probe by incorporating a wear-resistant structure on the outside of the probe. However, in actual use, when the probe is not in use and is not individually protected, it is prone to wear due to direct contact with the outside environment, resulting in inaccurate detection data. Utility Model Content

[0005] The purpose of this invention is to provide a probe for a water environment detection sensor to solve the problem mentioned in the background art that when the probe is not in use and is not individually protected, it is prone to wear when in direct contact with the outside world, resulting in inaccurate detection data.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a probe for a water environment detection sensor, including a plug, a wire fixedly connected to the top of the plug, and a probe body fixedly connected to the other end of the wire; an anti-detachment mechanism for improving the sealing of the plug and the wire is provided at the connection point, and a protective mechanism for protecting the probe body is provided on the outside of the probe body.

[0007] Furthermore, the protective mechanism includes a protective shell, which is fitted onto the outside of the probe body. The upper end of the probe body has a positioning groove that matches the protective shell. A rubber pad is provided at the upper end of the outer side of the protective shell, and the inner side of the rubber pad is in contact with the outer side of the probe body.

[0008] Furthermore, a limiting mechanism is provided at the upper end of the outer side of the probe body. The limiting mechanism includes a locking block, which is engaged with the outer side of the probe body. The left and right sides of the outer side of the protective shell are provided with slots that match the locking block.

[0009] Furthermore, connecting springs are provided at both the front and rear ends of the card block, and the card block and the probe body form an elastic structure through the connecting springs.

[0010] Furthermore, the anti-detachment mechanism includes a first elastic airbag, which is sleeved on the upper end of the plug. A compression plate is fixedly connected to the bottom end of the first elastic airbag, and a second elastic airbag is provided at the bottom end of the compression plate on the outside of the plug. An elastic sealing layer is sleeved on the outside of the second elastic airbag.

[0011] Furthermore, the extrusion plate has a connecting rod on its side, and a fixing block is provided at the upper end of the outer side of the plug, with a connecting groove matching the connecting rod at the bottom end of the fixing block.

[0012] Furthermore, a threaded groove is provided on the outer side of the fixing block, and a threaded sleeve is threadedly connected to the outer side of the fixing block, and the threaded sleeve is located on the outer side of the connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the probe body is not in use, the protective shell is fitted onto the outside of the probe body. The positioning groove at the bottom of the probe body keeps the protective shell in a locked position with the probe body, thereby fixing the protective shell in place. The protective shell can protect the probe body and reduce wear on the probe body.

[0015] Furthermore, when the protective shell is engaged, the rubber pad on the outside of the protective shell comes into contact with the probe body, thereby filling the gap between the protective shell and the probe body, thus protecting the bottom edge of the protective shell and reducing the possibility of the protective shell breaking and failing to protect the probe body.

[0016] Furthermore, the threaded sleeve and the fixed block are connected by threads and move downwards, thereby locking the position of the mating rod and fixing the position of the mating rod. This allows the second elastic airbag to remain filled with gas and seal the insertion interface, making the insertion slot and the plug fit more tightly and reducing dust from entering the insertion slot.

[0017] 2. By pulling out the locking block, the protective shell and the positioning groove are aligned. Then, the tension applied to the locking block is removed, allowing the locking block to automatically reset due to the elasticity of the connecting spring. This keeps the locking block and the groove in a locked state, thus restricting the position between the protective shell and the probe body. This effectively prevents the protective shell from separating from the probe body due to external forces in the locked state, improving the stability of the protective shell when locked. This provides better external physical protection for the probe body and reduces the possibility of damage to the probe body.

[0018] Furthermore, the elasticity of the connecting spring can assist the locking block in resetting its position, improving the flexibility of the locking block during repeated pulling. At the same time, the shape of the locking block facilitates pulling and reducing slippage during pulling, thus improving its applicability in use. Attached Figure Description

[0026] 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.

[0027] Example 1: As Figures 1-3 The technical solution shown addresses the problem that when the probe is not in use and is not individually protected, it is prone to wear and tear due to direct contact with the outside environment, leading to inaccurate detection data. The probe for this water environment detection sensor discloses a protective mechanism, including a plug 1. A wire 2 is fixedly connected to the top of the plug 1, and the other end of the wire 2 is fixedly connected to the probe body 3. A protective mechanism, including a protective shell 4, is provided on the outside of the probe body 3. The protective shell 4 is fitted onto the outside of the probe body 3. A positioning groove 5 matching the protective shell 4 is provided at the upper end of the probe body 3. A rubber pad 9 is provided at the upper end of the outer side of the protective shell 4, and the inner side of the rubber pad 9 is in contact with the outer side of the probe body 3.

[0028] In this example, such as Figure 2 and Figure 3 As shown, plug 1 is inserted into the sensor. When the probe body 3 is not in use, the protective shell 4 is placed on the outside of the probe body 3. The positioning groove 5 at the bottom of the probe body 3 keeps the protective shell 4 and the probe body 3 in a locked state, thereby fixing the position of the protective shell 4. At the same time, when the protective shell 4 is locked, the rubber pad 9 on the outside of the protective shell 4 contacts the probe body 3, thereby filling the gap between the protective shell 4 and the probe body 3, thus protecting the bottom edge of the protective shell 4 and reducing the possibility of the protective shell 4 breaking and failing to protect the probe body 3.

[0029] Example 2: Figures 1-3 and Figure 5 The technical solution shown addresses the issue that the protective shell 4 may accidentally detach when it is fitted onto the outside of the probe body 3 for protection. The probe for this water environment detection sensor discloses a limiting mechanism. A limiting mechanism is provided at the upper end of the probe body 3's outer side. This limiting mechanism includes a locking block 6, which is engaged with the outside of the probe body 3. The left and right sides of the protective shell 4 are provided with slots 7 that match the locking block 6. Connecting springs 8 are provided at both the front and rear ends of the locking block 6. The locking block 6 and the probe body 3 form an elastic structure through the connecting springs 8.

[0030] In this example, such as Figure 3 and Figure 5As shown, by pulling out the locking block 6, the protective shell 4 and the positioning groove 5 are aligned. Then, the tension applied to the locking block 6 is removed, causing the locking block 6 to automatically reset due to the elastic force of the connecting spring 8. This keeps the locking block 6 in a locked state with the locking groove 7, thereby restricting the position between the protective shell 4 and the probe body 3. This effectively prevents the protective shell 4 from separating from the probe body 3 due to external force, improving the stability of the protective shell 4 during locking, and thus providing better external physical protection for the probe body 3, reducing the possibility of damage to the probe body 3. Figure 3 As shown, the elastic force of the connecting spring 8 can assist the locking block 6 in resetting its position, improving the flexibility of the locking block 6 when repeatedly pulled out. At the same time, the shape of the locking block 6 facilitates pulling out and reduces slippage during pulling out, thus improving its applicability in use.

[0031] Example 3: Figure 1 , Figure 2 , Figure 4 and Figure 6 The technical solution shown addresses the problem of dust entering the gap between the probe and the sensor during the connection process, leading to insensitive contact. The probe for the water environment detection sensor discloses an anti-detachment mechanism. The connection between the plug 1 and the wire 2 is equipped with this mechanism to improve the sealing of the connection. The anti-detachment mechanism includes a first elastic airbag 13, which is fitted onto the upper outer side of the plug 1. A compression plate 14 is fixedly connected to the bottom of the first elastic airbag 13. A second elastic airbag 15 is located at the bottom of the compression plate 14 on the outer side of the plug 1, and an elastic sealing layer 16 is fitted onto the outer side of the second elastic airbag 15. A connecting rod 11 is located on the side of the compression plate 14. A fixing block 17 is located at the upper outer side of the plug 1, and a connecting groove 12 matching the connecting rod 11 is opened at the bottom of the fixing block 17. A threaded groove is opened on the outer side of the fixing block 17, and a threaded sleeve 10 is threadedly connected to the outer side of the fixing block 17, and the threaded sleeve 10 is located on the outer side of the connecting rod 11.

[0032] In this example, such as Figure 4 and Figure 6As shown, when plug 1 is inserted into the sensor, the compression plate 14 fitted on the upper end of plug 1 contacts the sensor, so that the top of the sensor can push the compression plate 14 upward. The second elastic airbag 15 and the elastic sealing layer 16 are then connected to the sensor slot. When the compression plate 14 is connected, the first elastic airbag 13 is compressed, so that the gas inside the first elastic airbag 13 is delivered to the inside of the second elastic airbag 15 through the hose. The connecting rod 11 is engaged with the connecting groove 12. When the top of the connecting rod 11 contacts the top of the inside of the connecting groove 12, the threaded sleeve 10 is rotated, so that the threaded sleeve 10 is threadedly connected to the fixing block 17 and moves downward, so that the threaded sleeve 10 locks the position of the connecting rod 11, completing the fixation of the position of the connecting rod 11, so that the inside of the second elastic airbag 15 can be filled with gas and the plug interface can be sealed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
