Abstract
Description
Technical Field
[0001] This invention relates to the field of conductivity sensor technology, and in particular to a cage-type cross-shaped droplet detection probe and a method for adjusting the probe length. Background Technology
[0002] Conductivity sensors are primarily used to monitor the conductivity parameters of media in pipeline systems. They detect changes in impedance across their input terminals by applying a potential across the electrodes, and then issue an alarm signal when the input state is reached. Based on the principle of liquid conductivity, the sensor uses dedicated electrodes to quickly detect the presence of water, converting this information into high or low level signals for output. Therefore, the length of the detection probe significantly impacts the detection results. A probe that is too long has poor applicability, while a probe that is too short cannot perform effective detection. Furthermore, the stability of the detection probe and the distance between them also affect the detection results.
[0003] Chinese patent CN219285085U discloses a conductivity sensor with adjustable probe length. This conductivity sensor with adjustable probe length facilitates the change of probe length by allowing the probe to slide on the connecting plug. A limiting end is set at one end that extends into the conductive housing to prevent the probe from falling off. The other end can pass through the connecting plug to facilitate the replacement of the probe and facilitate the change of probe length.
[0004] However, compared with existing technologies in related fields, after the detection probe undergoes multiple length changes, the diameter of the connector hole will increase due to friction. As a result, the detection probe will inevitably slide automatically due to gravity during use. In summary, the detection probe cannot be effectively positioned after its length changes, resulting in poor stability during equipment use. Summary of the Invention
[0005] The technical problem this invention aims to solve is that the length of the detection probe has a significant impact on the detection results. A probe that is too long has poor applicability in various scenarios, while a probe that is too short cannot perform effective detection. Furthermore, the stability of the detection probe and the distance between them also affect the detection results. To address the above-mentioned shortcomings of existing technologies, this invention provides a cage-type cross-shaped droplet detection probe and a method for adjusting its length.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0007] A cage-type cross-shaped droplet detection probe is constructed, comprising a conductive housing and conductive connecting plugs installed on the upper and lower sides of the conductive housing. The conductive connecting plug located on the lower side of the conductive housing is provided with a positioning assembly. The positioning assembly includes a fixed base. The top of the fixed base has multiple sliding grooves. Positioning clamps are slidably connected inside each sliding groove. A rotating knob is rotatably connected to the outer surface of the fixed base. Wedge-shaped blocks are fixedly provided on the inner wall of the rotating knob corresponding to the positions of the multiple positioning clamps. Multiple probes are inserted into the interior of the fixed base.
[0008] The conductive connector plug on the upper side of the conductive housing is equipped with a wire end.
[0009] By adopting the above technical solution, the wire end is connected to the conductive connector, and one of the conductive connectors connects the wire end to the conductive housing, while the other conductive connector connects the probe to the conductive housing. Thus, the wire end and the probe are connected to the conductive housing through the conductive connector.
[0010] Preferably, the conductive connector plug and the fixing base on the lower side of the conductive housing are provided with insertion holes at the positions of the multiple probes.
[0011] By adopting the above technical solution and utilizing the insertion hole, the stability of the probe during sliding can be improved.
[0012] Preferably, the positioning clamp has an arc-shaped groove on the side away from the wedge block, the probe is adapted to the arc-shaped groove, and a rubber layer is fixedly provided inside the arc-shaped groove.
[0013] By adopting the above technical solution, the probe can be clamped and constrained by the arc groove of the positioning clamp and the sliding groove, thereby improving the stability of the probe in the liquid.
[0014] Preferably, the fixed seat has a rotating groove at the position of the knob, and the fixed seat and the rotating groove are connected by an elastic element.
[0015] By adopting the above technical solution, the elastic force of the elastic element will cause the knob to reset, and at the same time, the knob can be kept in a fixed position when it is not subjected to external force.
[0016] Preferably, the bottom end of the plurality of probes is provided with a probe bundle.
[0017] By adopting the above technical solution, multiple probes can be constrained simultaneously using a probe bundle, thereby preventing the probes from affecting the detection effect due to shaking in the liquid.
[0018] Preferably, at least three probes are provided, and multiple probes are arranged side by side or in a circular arrangement.
[0019] By adopting the above technical solution, the probe bundles are arranged side by side or in a circular arrangement, so that the distance between adjacent probes is the same, thus avoiding the detection liquid from flowing out between the probe bundles and reducing the detection effect.
[0020] Preferably, when the probes are arranged in a circular pattern, the impedance between two adjacent sets of probes is 500 kΩ.
[0021] By adopting the above technical solution, the impedance between the two sets of probes is greatly reduced, thus improving the accuracy of the test.
[0022] A method for adjusting the probe length of a cage-type cross-shaped droplet detection probe, the method comprising the following steps:
[0023] S1: Rotate the torsion knob to release the wedge block from the clamping constraint of the positioning block;
[0024] S2: Adjust the probe length as needed;
[0025] S3: After adjusting the probe length, the torsion is reset;
[0026] S4: The wedge block causes multiple positioning clamps to slide simultaneously toward the center of the fixed base to fix the probe;
[0027] S5: The probe, after its length has been adjusted, is clamped into the liquid to be tested through the arc groove and the sliding groove for testing.
[0028] Preferably, after the probe length is adjusted, the elastic force of the elastic element resets the knob and fixes it.
[0029] The beneficial effects of this invention are as follows: This cage-type cross-shaped droplet detection probe, by setting a positioning component, can both use the arc groove of the positioning clamp and the sliding groove to clamp and constrain the probe, thereby improving the stability of the probe in the liquid, and at the same time, the positioning clamp can be removed from clamping and constraining the probe by rotating the knob, thus facilitating the user to quickly adjust the probe.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.
[0040] A cage-type cross-shaped droplet detection probe according to a preferred embodiment of the present invention; such as Figure 1-8As shown, the device includes a conductive housing 1 and conductive connecting plugs 2 installed on the upper and lower sides of the conductive housing 1. The conductive connecting plug 2 located on the lower side of the conductive housing 1 is equipped with a positioning assembly 3. The positioning assembly 3 includes a fixing base 301. Multiple sliding grooves 302 are formed on the top of the fixing base 301. Positioning clamps 303 are slidably connected inside each sliding groove 302. A rotating knob 304 is rotatably connected to the outer surface of the fixing base 301. A rotating groove 3011 is formed on the fixing base 301 at the position of the rotating knob 304. The fixing base 301 and the rotating groove 3011 are connected by an elastic element 3012. Wedge-shaped blocks 305 are fixedly provided on the inner wall of the rotating knob 304 corresponding to the positions of the multiple positioning clamps 303. Multiple probes 4 are inserted into the interior of the fixing base 301. Insertion holes are formed on the conductive connecting plug 2 on the lower side of the conductive housing 1 and on the fixing base 301 at the positions of the multiple probes 4. A conductive connector 2 on the upper side of the housing 1 is fitted with a wire end 5. The wire end 5 is connected to the conductive connector 2, and one of the conductive connectors 2 connects the wire end 5 to the conductive housing 1. The other conductive connector 2 connects the probe 4 to the conductive housing 1. Thus, the wire end 5 and the probe 4 are connected and connected to the housing 1 through the conductive connector 2. The bottom of the multiple probes 4 is provided with a probe bundle 6. The probe bundle 6 can constrain the multiple probes 4 at the same time, thereby preventing the probes 4 from affecting the detection effect due to shaking in the liquid. The positioning clamp 303 has an arc groove 3031 on the side away from the wedge block 305. The probe 4 is adapted to the arc groove 3031. A rubber layer is fixed inside the arc groove 3031. By using the arc groove 3031 of the positioning clamp 303 to cooperate with the sliding groove 302, the probe 4 can be clamped and constrained, thereby improving the stability of the probe 4 in the liquid.
[0041] Furthermore, multiple probes 4 are configured, which can be arranged side-by-side or in other ways. The probes 4 are circular, forming a probe ring with a diameter of 15 cm. Utilizing the characteristic that the distance between any two points of a circle is equal, better detection results can be achieved. The circular cage-like design allows for no blind spots in the wiring direction, enabling detection even with a small volume, and ensuring that any two adjacent probes can detect droplets upon contact. The cage-like cross-type droplet detection probe has distributed capacitance and relative impedance. Tests at a frequency of 10 kHz showed that the existing impedance is 500 kΩ, while the impedance of conventional detection probes is >10 MΩ. The cage-like probe also has a probe bundle 6 at the other end to fix the probe and prevent the detection probe from swaying in the liquid, thus avoiding interference with the detection effect.
[0042] In use, when the length of probe 4 needs to be adjusted, the knob 304 is rotated, causing the wedge block 305 to no longer press against the positioning clamp block 303. At this time, the positioning clamp block 303 no longer clamps and constrains probe 4. The length of probe 4 can be adjusted by pulling it outward or pushing it inward. After the length adjustment is completed, the knob 304 is released, and the elastic force of the elastic element 3012 will cause the knob 304 to reset, while also allowing the knob 304 to remain in a fixed position when not subjected to external force. After the knob 304 is reset, the wedge block 305 pushes against the positioning clamp block 303, thereby causing multiple positioning clamp blocks 303 to slide together toward the center point of the fixed seat 301. By utilizing the arc groove 3031 of the positioning clamp block 303 in cooperation with the sliding groove 302, the probe 4 can be clamped and constrained, thereby improving the stability of probe 4 in the liquid.
[0043] A method for adjusting the probe length of a cage-type cross-shaped droplet detection probe, the method comprising the following steps:
[0044] S1: Rotate the torsion knob to release the wedge block from the clamping constraint of the positioning block;
[0045] S2: Adjust the probe length as needed;
[0046] S3: After adjusting the probe length, the torsion is reset;
[0047] S4: The wedge block causes multiple positioning clamps to slide simultaneously toward the center of the fixed base to fix the probe;
[0048] S5: The probe, after its length has been adjusted, is clamped into the liquid to be tested through the arc groove and the sliding groove for testing.
[0049] Furthermore, after the probe length is adjusted, the elastic force of the elastic element resets the knob and fixes it in place.

Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
