Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to a soil pH sensor with adjustable connection wire length. Background Technology

[0002] Soil pH sensors are mainly composed of a metal sensor and a function value switching device. The metal sensor comes into contact with the soil and generates an electric current through the redox reaction in the chemical reaction. The magnitude of the current drives the ammeter to display different pH and humidity values. This type of sensor can be directly inserted into the soil to measure acidity and alkalinity.

[0003] Publication number CN219016311U discloses a soil pH sensor. By using a sliding plate to restrict the position of two probes, the strength of the probes is increased, preventing them from shifting when they encounter rocks, thus avoiding breakage at the base of the probes and reducing the failure rate. However, this patent still has the following problems in practical use:

[0004] By placing the connecting wire directly inside the receiving cavity, the wire may become tangled, making it difficult to adjust the length of the wire. Furthermore, when using the sensor, the lack of a limit on the connecting wire may cause it to slip out of the slot, affecting its use.

[0005] A soil pH sensor with adjustable connection length is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a soil pH sensor with an adjustable connecting wire length, in order to solve the problems mentioned in the background art. Currently, by installing the blower of the static eliminator inside the sleeve of the rotating roller, the ion air is blown out from the inside to the outside through the sleeve, which cannot actually have an effect on the outermost film. At the same time, because the film is rolled up on the outer wall of the sleeve, the ion air cannot be blown out, thus affecting the effect of static removal. In addition, the film may roll up during the ion air blowing process, causing the subsequent shearing to be offset. Furthermore, the fixed air delivery channel has a small elimination range, which has certain limitations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a soil pH sensor with adjustable connecting wire length, comprising a sensor body and a connecting wire fixed to one side of the sensor body;

[0008] Also includes:

[0009] The connecting wire is provided with a storage and adjustment component. The storage and adjustment component includes a connecting shell, and a winding roller is rotatably connected inside the connecting shell. A rotating block is rotatably connected to the front of the connecting shell, and the rotating block is fixedly connected to the winding roller. A guide cylinder is fixedly connected to one side of the connecting shell, and the guide cylinder communicates with the connecting shell. The connecting wire slides on the guide cylinder and is wound on the winding roller.

[0010] Among them, connecting blocks are symmetrically fixed on the upper and lower sides of the connecting line, and a first spring is fixedly connected between the connecting blocks and the guide cylinder;

[0011] The top of the guide cylinder is fixedly connected to a connecting plate, and the connecting plate has a groove inside, and a sliding plate is slidably connected inside the groove.

[0012] Preferably, a mounting block is fixedly connected to one side of the connecting plate, and the mounting block is fixed to the sliding plate with bolts.

[0013] Preferably, a second spring is fixedly connected between the guide cylinder and the slide plate, and connecting plates are symmetrically fixed to the top of the guide cylinder.

[0014] Preferably, a rotating rod is rotatably connected to the front of the connecting piece, and the rotating rod is rotatably connected to the slide plate. The rotating rod and the pivot of the slide plate are slidable, and a clamping block is rotatably connected to one side of the rotating rod, and the clamping block abuts against the connecting line.

[0015] Preferably, the clamping block is T-shaped.

[0016] Preferably, a disassembly assembly is provided on the other side of the sensor body. The disassembly assembly includes a probe, which is slidably connected to the sensor body. A fixing strip is fixedly connected between the probes, and a block is fixedly connected to one side of the fixing strip. A through groove is provided on the other side of the sensor body, and the block is slidably connected to the through groove.

[0017] Preferably, a third spring is fixedly connected inside the through groove, and a locking block is fixedly connected to the bottom of the third spring. The locking block engages with the block, and a telescopic rod is fixedly connected between the locking block and the sensor body. A pull block is fixedly connected to one side of the telescopic rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this soil pH sensor with adjustable connecting wire length can retract and store the connecting wire, avoiding tangling of the wires, and can also fix the position of the connecting wire, preventing the length of the connecting wire from changing arbitrarily. The specific details are as follows:

[0019] 1. Unscrew the bolt to release the limit on the slide plate, then press down on the slide plate. The slide plate will compress the second spring, and then the slide plate will drive the rotating rods on both sides to rotate. At this time, the first spring will rebound, and the connecting block will cause the connecting line to lengthen. Then the lengthened part of the connecting line will come out from one side of the guide cylinder, so that the rotating block and the take-up roller will take up the connecting line. When the connecting line is wound to the desired length, release the slide plate. The second spring will cause the slide plate to return to its original position, and the rotating rod will cause the clamp to release the limit on the connecting line, so that the clamp can fix the position of the connecting line again, thereby realizing the adjustment and fixation of the length of the connecting line.

[0020] 2. This causes the pull block to rise, which in turn compresses the third spring. Simultaneously, the pull block disengages from the inside of the block, thus releasing the block's restriction. The block can then be extracted from the inside of the sensor body, allowing the probe to also disengage from the sensor body, enabling the probe to be disassembled and replaced in reverse.

A guide cylinder 304 is provided, and the guide cylinder 304 communicates with the connecting shell 301. The connecting line 2 slides on the guide cylinder 304 and is wound on the winding roller 302. Connecting blocks 305 are symmetrically fixed on the upper and lower sides of the connecting line 2, and a first spring 306 is fixedly connected between the connecting blocks 305 and the guide cylinder 304. A connecting plate 307 is fixedly connected to the top of the guide cylinder 304, and a groove 308 is provided inside the connecting plate 307. A sliding plate 309 is slidably connected inside the groove 308. Figure 3 , 4 As shown, pressing down on the slide plate 309 compresses the second spring 310, causing the slide plate 309 to rotate the rotating rods 312 on both sides. At this time, the first spring 306 rebounds, causing the connecting block 305 to move. The connecting block 305 then stretches the length of the connecting line 2, and the stretched portion of the connecting line 2 comes off one side of the guide cylinder 304. At this time, the rotating block 303 can be rotated so that the rotating block 303, along with the winding roller 302, winds up the connecting line 2. When the connecting line 2 is wound to the desired length, the slide plate 309 is released, and the second spring 310 causes the slide plate 309 to return to its original position.

[0029] A mounting block 3091 is fixedly connected to one side of the connecting plate 307, and the mounting block 3091 is fixed to the slide plate 309 by bolts 3092, such as Figure 3As shown, bolt 3092 can be unscrewed to release the restriction on slide plate 309. A second spring 310 is fixedly connected between guide cylinder 304 and slide plate 309. A connecting piece 311 is symmetrically fixed to the top of guide cylinder 304. A rotating rod 312 is rotatably connected to the front of connecting piece 311. The rotating rod 312 is rotatably connected to slide plate 309. The rotating rod 312 can slide at the pivot of slide plate 309. A clamping block 313 is rotatably connected to one side of rotating rod 312. The clamping block 313 abuts against connecting line 2. The clamping block 313 is T-shaped.

[0030] On the other side of the sensor body 1, a disassembly assembly 4 is provided. The disassembly assembly 4 includes a probe 401, which is slidably connected to the sensor body 1. A fixing strip 402 is fixedly connected between the probes 401, and a block 403 is fixedly connected to one side of the fixing strip 402. A through groove 404 is provided on the other side of the sensor body 1, and the block 403 is slidably connected to the through groove 404. A third spring 405 is fixedly connected inside the through groove 404, and a locking block 406 is fixedly connected to the bottom of the third spring 405. The locking block 406 engages with the block 403, and a telescopic rod 407 is fixedly connected between the locking block 406 and the sensor body 1. A pull block 408 is fixedly connected to one side of the telescopic rod 407. Figure 5 As shown, the pull block 408 can be pulled upwards, causing the pull block 408 to lift the position of the locking block 406. Then the locking block 406 will compress the third spring 405, and at the same time, the locking block 406 will disengage from the inside of the block 403, thereby releasing the restriction on the block 403. Then the block 403 can be pulled out from the inside of the sensor body 1, thereby causing the probe 401 to also disengage from the inside of the sensor body 1, so that the probe 401 can be disassembled and replaced in reverse.

[0031] Working principle: Before using this soil pH sensor with adjustable connection cable length, it is necessary to check the overall condition of the device to ensure it can function normally. Figure 1 - Figure 5As shown, firstly, when it is necessary to adjust the connection length of the connecting line 2, the bolt 3092 can be unscrewed to release the limit on the slide plate 309. Then, press the slide plate 309 down. At this time, the slide plate 309 will compress the second spring 310, and then the slide plate 309 will drive the rotating rods 312 on both sides to rotate. At this time, the first spring 306 will rebound, and then the first spring 306 will drive the connecting block 305 to move. Then, the connecting block 305 will cause the length of the connecting line 2 to be stretched. Then, the stretched part of the connecting line 2 will come out from one side of the guide cylinder 304. The rotating block 303 can be rotated so that the rotating block 303 and the winding roller 302 can wind the connecting wire 2. When the connecting wire 2 is wound to the desired length, the slide plate 309 is released, the second spring 310 will drive the slide plate 309 to return to its original position, and then the rotating rod 312 will drive the clamping block 313 to release the abutment limit on the connecting wire 2. The rotating rod 312 will then be driven to reverse and return to its original position, so that the clamping block 313 can fix the position of the connecting wire 2 again. Then the bolt 3092 is screwed back into the slide plate 309, thereby realizing the adjustment and fixation of the length of the connecting wire 2.

[0032] Pulling the pull block 408 upwards will cause the pull block 408 to lift the position of the locking block 406. Then the locking block 406 will compress the third spring 405 and disengage from the inside of the block 403, thereby releasing the restriction on the block 403. Then the block 403 can be pulled out from the inside of the sensor body 1, thereby causing the probe 401 to also disengage from the inside of the sensor body 1, so that the probe 401 can be disassembled and replaced in reverse.

[0033] Although the present invention 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 invention should be included within the protection scope of the present invention.
