Description

Technical Field

[0001] This utility model belongs to the technical field of nitrate nitrogen analyzers, and in particular relates to a nitrate nitrogen analyzer with temperature compensation function. Background Technology

[0002] A nitrate nitrogen analyzer is an instrument used to measure the nitrate content in water, and it is crucial for environmental monitoring, water quality management, and industrial process control. Nitrate nitrogen analyzers with temperature compensation functions can automatically adjust the measurement results when the temperature changes, ensuring the accuracy and stability of the data. Examples include the HK-8210 online nitrate nitrogen monitor, the NT3 series online nitrate nitrogen detector, and the OTT ecoN ultraviolet nitrate nitrogen analyzer. Therefore, it can be seen that existing environmental monitoring instruments basically meet people's needs, but the following problems still exist.

[0003] When using a nitrate nitrogen analyzer with temperature compensation, the operator inserts the probe into the liquid to be tested. The probe transmits the collected data to the nitrate nitrogen analyzer via a data cable. The analyzer then analyzes the data. After use, the operator disconnects the data cable connecting the probe and the analyzer and stores the analyzer, probe, and data cable separately in the equipment case. Reusing the analyzer may require reassembling these components. Furthermore, when testing liquids at multiple locations, repeated disassembly and reassembly of the analyzer, data cable, and probe may be cumbersome. Therefore, we propose a nitrate nitrogen analyzer with temperature compensation. Utility Model Content

[0004] This invention provides a nitrate nitrogen analyzer with temperature compensation function. The operator inserts the data cable into the positioning sleeve, then installs the winding rod on the positioning sleeve and winds the data cable around the surface of the winding rod for easy storage. The detection head is stored in the storage cover and storage sleeve. When the operator is testing at multiple locations, there is no need to repeatedly disassemble and reassemble the nitrate nitrogen analyzer, data cable, and detection head, thus improving the convenience of operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nitrate nitrogen analyzer with temperature compensation function, comprising a detector body, a positioning sleeve fixed to the surface of the detector body, and a winding rod sleeved on the surface of the positioning sleeve, with protective cotton and a storage sleeve fixed to the two ends of the winding rod respectively, a bolt post threaded in the middle of the positioning sleeve, and a stop block fixed to the end of the bolt post, with an extension plate fixed around the stop block that fits against the storage sleeve, a storage sleeve fixed to the outer wall of the detector body, and a storage cover provided at the end of the storage sleeve, with the storage cover elastically connected to the storage sleeve.

[0006] Furthermore, a first spring groove is provided in the middle of the bolt column, and a first spring and a push rod are respectively provided inside the first spring groove. The two ends of the first spring abut against the inner wall of the first spring groove and the surface of the push rod, respectively. A stop block is fixed at the end of the push rod.

[0007] Furthermore, guide blocks are symmetrically fixed at both ends of the abutment block, and guide grooves are provided on the surface of the guide blocks and formed on the inner wall of the positioning sleeve.

[0008] Furthermore, positioning blocks are inserted around the protective cotton, and the positioning blocks are all fixed to the main body of the detector.

[0009] Furthermore, the protective cotton has rectangular notches around its perimeter, and these rectangular notches match the rectangular blocks provided by the positioning blocks.

[0010] Furthermore, the surface of the storage sleeve is symmetrically fixed with second spring grooves, and each of the second spring grooves is provided with a pull rod and a limiting block. The limiting block is rotatably connected to the pull rod. The surfaces of the pull rod and the limiting block are both wrapped with second springs, and the two ends of the second springs respectively abut against the surface of the limiting block and the inner wall of the second spring groove. The ends of the pull rods are all fixed with fixing blocks, and the fixing blocks are fixed to the storage cover.

[0011] Furthermore, each of the limiting blocks has a rotating shaft penetrating one side of the pull rod, and the rotating shaft is fixed to the inner wall of the pull rod.

[0012] Furthermore, the inner walls of both the storage sleeve and the storage lid are lined with protective cotton.

[0013] The beneficial effects of this utility model are:

[0014] 1. This nitrate nitrogen analyzer with temperature compensation function is equipped with a positioning sleeve, bolt post, stop block, winding rod, storage sleeve, and storage cover. The operator inserts the data cable into the positioning sleeve and places the winding rod on its surface. Then, the operator moves the stop block, which moves the bolt post. The bolt post is threaded onto the positioning sleeve, fixing the winding rod to its surface. The operator then winds the data cable onto the winding rod for easy storage. The operator inserts the detection head into the storage sleeve and cover, which then store the detection head. When performing tests at multiple locations, the operator no longer needs to repeatedly disassemble and reassemble the nitrate nitrogen analyzer, data cable, and detection head, improving ease of use.

[0015] 2. The nitrate nitrogen analyzer with temperature compensation function is equipped with a first spring, a first spring groove, a stop block and a push rod. After the first spring recovers from elastic deformation, the first spring pushes the stop block to move through the push rod, so that the stop block abuts against the data line, and the stability of the data line inserted into the positioning sleeve is achieved.

[0027] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] Example:

[0029] Please see Figure 1 - Figure 9 A nitrate nitrogen analyzer with temperature compensation function includes a detector body 1. A positioning sleeve 2 is heat-fused to the surface of the detector body 1, and a winding rod 12 is fitted onto the surface of the positioning sleeve 2. Protective cotton 4 and a storage sleeve 3 are heat-fused to both ends of the winding rod 12, respectively. A bolt post 6 is threadedly installed in the middle of the positioning sleeve 2, and a stop block 10 is heat-fused to the end of the bolt post 6. An extension plate 11 that fits into the storage sleeve 3 is heat-fused to the periphery of the stop block 10. The storage sleeve 3 is heat-fused to the outer wall of the detector body 1. Furthermore, the storage sleeve 3 is provided with a storage cover 15 at its end, and the storage cover 15 is elastically connected to the storage sleeve 3. Symmetrically heat-fused second spring grooves 14 are formed on the surface of the storage sleeve 3, and each of the second spring grooves 14 contains a pull rod 20 and a limiting block 13. The limiting block 13 is rotatably connected to the pull rod 20. A rotating shaft 21 passes through the side of the limiting block 13 inserted into the pull rod 20, and the rotating shaft 21 is heat-fused to the inner wall of the pull rod 20. A second spring 19 is wound around the surface of both the pull rod 20 and the limiting block 13. The two ends of the pull rod 20 abut against the surface of the limiting block 13 and the inner wall of the second spring groove 14, respectively. Each end of the pull rod 20 is heat-fused with a fixing block 16, which is also heat-fused to the storage cover 15. When the operator needs to fix the data cable, the operator first moves the data cable and inserts it into the notches on both sides of the positioning sleeve 2. Then, the operator moves the winding rod 12. The oblong holes on both sides of the winding rod 12 are parallel to those on both sides of the positioning sleeve 2. The operator then places the winding rod 12 onto the positioning sleeve 2. Next, the operator moves the stop block 10, which moves the bolt post 6, so that the thread on the surface of the bolt post 6 and the internal thread on the inner wall of the positioning sleeve 2 are threaded together, so that the bolt post 6 is installed in the positioning sleeve 2. The stop block 10 moves the extension plate 11, so that the extension plate 11 abuts against the surface of the storage sleeve 3, fixing the winding rod 12 on the positioning sleeve 2. Then the operator takes the data cable and winds the data cable around the surface of the winding rod 12, making it convenient for the operator to wind the data cable.

[0030] When the operator needs to store the detection head, the operator first pulls the storage cover 15. The storage cover 15 moves the fixing block 16, and as the fixing block 16 moves, it drives the rotating shaft 21 to move via the pull rod 20. The rotating shaft 21 drives the limiting block 13 to slide within the second spring groove 14. After the limiting block 13 compresses the second spring 19, the second spring 19 undergoes elastic deformation. After the second spring 19 undergoes elastic deformation, it avoids the limiting block 13, causing the pull rod 20 and the limiting block 13 to move out of the second spring groove 14, and the storage cover 15 to separate from the storage sleeve 3. Then, the operator pushes the storage cover 15, which drives the pull rod 20 to move via the fixing block 16, causing the pull rod 20 to drive the rotating shaft 21 to move at the end of the limiting block 13. As the device rotates, the storage cover 15 opens the storage sleeve 3. The operator then inserts the detection head into the storage sleeve 3. Next, the operator pushes the storage cover 15 again, and the storage cover 15 moves the pull rod 20 through the fixing block 16. The pull rod 20 rotates at the end of the limiting block 13 through the rotating shaft 21, making the storage cover 15 and the storage sleeve 3 parallel to each other. The operator releases the storage cover 15, and the storage cover 15 no longer compresses the second spring 19 through the fixing block 16. The second spring 19 recovers its elastic deformation and pushes the limiting block 13 to move. The limiting block 13 pulls the pull rod 20 through the rotating shaft 21, and the pull rod 20 moves the storage cover 15 through the fixing block 16, so that the storage cover 15 is fitted onto the surface of the detection head for easy storage.

[0031] In other embodiments, a first spring groove 8 is provided in the middle of the bolt post 6, and a first spring 17 and a push rod 9 are respectively provided inside the first spring groove 8. The two ends of the first spring 17 abut against the inner wall of the first spring groove 8 and the surface of the push rod 9, respectively. A stop block 10 is fixed to the end of the push rod 9. When the operator installs the bolt post 6 into the positioning sleeve 2, the bolt post 6 drives the push rod 9 to move through the first spring groove 8. The push rod 9 drives the stop block 10 to move, so that the stop block 10 is inserted into the positioning sleeve 2. At the same time, the stop block 10 is attached to the surface of the data cable. When the bolt post 6 is threaded into the positioning sleeve 2, the bolt post 6 pushes the first spring groove 8 to slide on the surface of the push rod 9. When the first spring groove 8 slides on the surface of the push rod 9, the inner wall of the first spring groove 8 squeezes the first spring 17, causing the first spring 17 to undergo elastic deformation. Through the elastic deformation of the first spring 17, the first spring 17 pushes the push rod 9 to move. The push rod 9 pushes the stop block 10 to move, so that the stop block 10 abuts against the surface of the data cable, which facilitates the fixing of the data cable.

[0032] In other embodiments, guide blocks 18 are symmetrically heat-fused to both ends of the abutment block 10, and guide grooves 7 are provided on the surface of the guide blocks 18 on the inner wall of the positioning sleeve 2. The abutment block 10 drives the guide blocks 18 to be inserted into the guide grooves 7, so that the guide blocks 18 and the guide grooves 7 restrict the movement trajectory of the abutment block 10 in the positioning sleeve 2, and prevent the abutment block 10 from rotating with the bolt column 6.

[0033] In other embodiments, positioning blocks 5 are inserted around the protective cotton 4, and the positioning blocks 5 are all heat-fused to the main body 1 of the detector. Rectangular notches are opened around the protective cotton 4, and the rectangular notches opened around the protective cotton 4 match the rectangular blocks set on the positioning blocks 5. When the operator moves the protective cotton 4 by the winding rod 12, so that the protective cotton 4 is in contact with the surface of the detector main body 1, the rectangular notches opened around the protective cotton 4 are fitted onto the surface of the positioning blocks 5 fixed on the surface of the detector main body 1, so that the positioning blocks 5 restrict the protective cotton 4 and prevent the protective cotton 4 from rotating on the surface of the detector main body 1, thereby increasing the stability of the winding rod 12.

[0034] In other embodiments, the inner walls of both the storage sleeve 3 and the storage cover 15 are fitted with protective cotton 4. When the operator inserts the detection head into the storage sleeve 3 and the storage cover 15 is placed on the surface of the detection head, the protective cotton 4, which is heat-fused to the inner walls of the storage sleeve 3 and the storage cover 15, blocks the detection head from impacting the inner walls of the storage sleeve 3 and the storage cover 15, thereby increasing the safety of the detection head placed inside the storage sleeve 3 and the storage cover 15.

[0035] 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 variations 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.
