Description

Technical Field

[0001] This invention relates to the field of heavy metal detection technology in surface water, and particularly to a heavy metal content detector for surface water. Background Technology

[0002] Surface water is an important component of natural water resources and a vital material foundation for human survival and development. Testing surface water for heavy metals can ensure drinking water safety, protect public health, and also provide insights into water quality trends and pollution levels, offering a scientific basis for water quality assessment, environmental planning, and management.

[0003] A water quality heavy metal detector is a device specifically designed to detect the heavy metal content in water bodies. It plays a crucial role in the monitoring of surface water, enabling the detector to detect heavy metal ions in water bodies with high sensitivity and calculate their concentration values, thereby providing a reliable scientific basis for the assessment and detection of surface water quality.

[0004] Currently, in surface water heavy metal testing, the process typically involves the testing engineer bringing the instrument to the vicinity of the surface water to be tested, collecting samples in a collection container, and then using the instrument for analysis. Because this operation often takes place outdoors, the following shortcomings exist in the testing process:

[0005] 1. Enrichment devices often need to be supported by an external support frame, making the preparation for use and the storage after enrichment quite cumbersome. The external support frame can also be a burden to carry when going out.

[0006] 2. Since the heavy metal content of the sampled water is unknown, engineers often wear gloves when operating the equipment. However, when loading and unloading the enriched filter membrane, the gloves often need to be contaminated with the sampled water before operating the detector. The sampled water can easily come into contact with the detector's related equipment, causing corrosion and water immersion malfunctions. Summary of the Invention

[0007] The purpose of this invention is to provide a surface water heavy metal content detector that is convenient for outdoor use, avoids contamination of the sampled water, and improves the lifespan of the equipment.

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a surface water heavy metal content detector, comprising a detector body and an enrichment component;

[0009] The detector body is detachably connected to the enrichment component through an assembly assembly. The assembly assembly includes a mounting plate, a flip bar, a rotating shaft, and an assembly column. The mounting plate is fixed to the outside of the detector body. One end of the flip bar is rotatably connected to the mounting plate through the rotating shaft, and the assembly column is fixed to the other end of the flip bar.

[0010] The enrichment component includes an enrichment device, an assembly cylinder, and an assembly hole. The assembly cylinder is fixed to the outside of the enrichment device, and the assembly hole is opened on the bottom surface of the assembly cylinder. The assembly cylinder is inserted into the assembly column through the assembly hole.

[0011] The enrichment assembly also includes a detachable frame plate, a displacement assembly, a filter assembly, a loading and unloading assembly, a stationary pipe assembly, and a return assembly. The detachable frame plate is detachably connected to the displacement assembly via the loading and unloading assembly. The displacement assembly can move along the height direction of the enrichment device. The filter assembly is installed on the detachable frame plate, and the return assembly is connected to the displacement assembly.

[0012] A further feature of the present invention is that: a water pipe is provided at the bottom of the enrichment device, the water pipe extends into the filter assembly and is connected to the fixed pipe assembly, and the displacement assembly includes a guide rail opened on the outside of the enrichment device and a shift frame that slides in contact with the outside of the enrichment device. A slider is fixed on the side of the shift frame near the enrichment device, and the shift frame slides along the guide rail through the slider.

[0013] By adopting the above technical solution, the shifting frame can move vertically along the guide rail on the outside of the enrichment device.

[0014] A further embodiment of the present invention is that the filter assembly includes a housing fixed to the bottom of the detachable frame plate, an inlet pipe fixed to the top of the housing, a detection chamber opened inside the housing, and a filter device detachably installed inside the detection chamber.

[0015] By adopting the above technical solution, during the enrichment process, the outer shell drives the filter device to be immersed in the sampled water, and the suction tube moves down synchronously with the outer shell under the fixation of the tube assembly.

[0016] A further configuration of the present invention is as follows: the detection cavity includes a top cavity, a transition cavity, and a filter cavity sequentially formed from top to bottom within the outer casing; the filter device includes a filter element and an ejector element respectively installed in the filter cavity and the transition cavity; the filter element is fixed to the outer casing by a locking element.

[0017] A further configuration of the present invention is as follows: the filter element includes a mounting frame inserted inside the filter cavity, a filter membrane fixed inside the mounting frame, and a sealing ring fixed outside the mounting frame, wherein the outer side of the mounting frame is in contact with the transition cavity through the sealing ring.

[0018] By adopting the above technical solution, the sealing ring is made to fit tightly with the transition cavity, thus preventing the sampling water from seeping into the shell.

[0019] A further feature of the present invention is that the loading and unloading assembly includes a plug assembly and a force-bearing panel that are detachably connected to each other;

[0020] The insert assembly includes an insert block fixed to a detachable frame plate on one side, a locking cavity opened on the side of the insert block away from the detachable frame plate, a locking block and a magnetic plate fixed in the locking cavity, and the surface of the locking block has two symmetrically distributed inclined surfaces.

[0021] By adopting the above technical solution, it is convenient to connect the card block to the force-bearing panel through the inclined surface.

[0022] A further feature of the present invention is that the water pipe extends into the inlet pipe and is connected to the fixed pipe assembly. The surface of the detachable frame plate is provided with a sliding opening, and the interior of the detachable frame plate is provided with a through groove and an installation groove communicating with the sliding opening. The fixed pipe assembly includes a driving assembly slidably disposed in the through groove, a clamping assembly that abuts against the outside of the water pipe, and a tightening assembly connected to the driving assembly.

[0023] By adopting the above technical solution, the water pipe is fixed by applying force through the clamping component, and the clamping state of the clamping component is controlled by the tensioning component.

[0024] A further configuration of the present invention is as follows: the driving assembly includes a push plate that slides in contact with the through groove on its outer side, a finger block fixed on the outer side of the push plate, and a third spring that is fixed at both ends to the through groove and the push plate respectively; the clamping assembly includes clamping arms symmetrically arranged on the outer side of the water pipe, an arc plate fixed at one end of the clamping arm, a shaft column fixedly connected to the clamping arm at its bottom end, and a bracket fixed in the top cavity; the outer side of the shaft column is rotatably connected to the bracket; a first coil spring that helps the shaft column rotate back to its original position is fixedly mounted on the bracket; and the inner side of the arc plate abuts against the water pipe.

[0025] By adopting the above technical solution, the water pipe is clamped on the outside by the arc plate, so that the water pipe can move synchronously with the up and down movement of the outer shell after it is inserted into the outer shell.

[0026] A further feature of the present invention is that the return assembly includes a recovery cylinder and a return button. The recovery cylinder includes a protective cylinder fixedly connected to the enrichment device on the outside, a spiral tube rotatably installed inside the protective cylinder, two limiting discs fixed at intervals on the outside of the spiral tube, and a winding rope wound on the spiral tube. The bottom end of the winding rope slides out of the protective cylinder and is fixed to the transfer frame. A second coil spring for rotational return is installed on the outside of the spiral tube.

[0027] By adopting the above technical solution, when the rotating tube needs to be reset, the second coil spring can drive the rotating tube back to its original position.

[0028] A further feature of the present invention is that a control module is embedded in the detachable frame plate.

[0029] The beneficial effects of this invention are:

[0030] 1. The enrichment device does not require an external support frame for combined use. Simply rotate the flap on the detector body and let the assembly column quickly support the enrichment device to keep it in a ready position for use. This optimizes the preparation operation before enrichment and also reduces the burden on engineers to carry materials when going out.

[0031] 2. The filter assembly for enrichment is installed on a detachable frame plate. The filter assembly can be moved freely towards the enrichment container by moving the frame to meet the requirements of contact with the sampled water and enrichment discharge. The operation is orderly and quick, which can improve the convenience of enrichment operation.

[0032] 3. After enrichment, the detachable shelf can be removed from the transfer rack through the loading and unloading assembly. The engineer does not need to touch the filter membrane for loading and unloading. He only needs to operate the detachable shelf to make the locking and spring parts cooperate to quickly send the filter membrane to the main body of the detector. This reduces the contact between the sampled water and the engineer's hands, thus protecting the hands. It can also protect the main body of the detector and other equipment that need to be touched during operation, such as the keyboard, from corrosion and water immersion.

[0033] 4. After the frame is moved, it can automatically return to its original position through the return component. After the water quality test is completed, the detachable frame plate can drive the filter to quickly reset, making it convenient to pack and carry, thereby improving the efficiency of outdoor water quality testing.

[0051] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely 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 scope of protection of the present invention.

[0052] This invention specifically provides a surface water heavy metal content detector, please refer to... Figure 1 It includes the detector body 1 and the enrichment component 2.

[0053] The detector body 1 is detachably connected to the enrichment component 2 through the assembly components, so that the enrichment component 2 no longer needs to be loaded with an external support frame structure, which facilitates weight reduction of components during outdoor sampling and improves the convenience of detection.

[0054] When implementing, please refer to Figure 2 The assembly components include a mounting plate 111, a flip bar 112, a rotating shaft 113, and an assembly column 114. The mounting plate 111 is fixed to the outside of the detector body 1. One end of the flip bar 112 is rotatably connected to the mounting plate 111 via the rotating shaft 113. The assembly column 114 is fixed to the other end of the flip bar 112. By setting the rotational friction between the rotating shaft 113 and the mounting plate 111, the flip bar 112 can be rotated under a certain thrust, which makes it easy to rotate the flip bar 112 into the underside of the mounting plate 111. It also makes it easy to prevent the flip bar 112 from rotating easily after it has been rotated out.

[0055] The enrichment component 2 includes an enrichment device 21, an assembly cylinder 22, and an assembly hole 23. The assembly cylinder 22 is fixed to the outside of the enrichment device 21, and the assembly hole 23 is opened on the bottom surface of the assembly cylinder 22. The assembly cylinder 22 is inserted into the assembly column 114 through the assembly hole 23. The inner wall of the assembly hole 23 has a polygonal structure. The shape of the assembly column 114 matches the assembly hole 23, so that when the assembly hole 23 is inserted into the assembly column 114, the enrichment device 21 will not rotate circumferentially, thereby improving the placement stability of the enrichment device 21. Thus, when sampling and testing outdoors, there is no need to support the enrichment device 21 with an external support frame, which provides convenience for the use and storage of the enrichment device 21.

[0056] It is worth noting that the detector body 1 and the enrichment device 21 are common water quality heavy metal detection components. The modification of this technical solution is only implemented on the outer shell of the detector body 1 and the enrichment device 21. Therefore, the usage and principle of the detector body 1 and the enrichment device 21 will not be explained in detail.

[0057] Further, please refer to Figure 3 The enrichment component 2 also includes a detachable frame plate 3, a displacement component 4, a filter component 5, a loading and unloading component 6, a stationary pipe component 7, and a return component 8. The detachable frame plate 3 is detachably connected to the displacement component 4 through the loading and unloading component 6. The displacement component 4 can move along the height direction of the enrichment device 21. The filter component 5 is installed on the detachable frame plate 3, so that when the water sample is enriched on the filter component 5, the filter component 5 can be moved to the detector body 1 for detection by removing the detachable frame plate 3. The whole process does not require hand contact with the filter component 5, so as to reduce contact with the sampled water. The return component 8 is connected to the displacement component 4, and the displacement component 4 is reset after being moved down through the return component 8.

[0058] Specifically, please refer to Figure 3 and Figure 4 The enrichment device 21 is equipped with a water pipe 24 at its bottom. Before each enrichment of water quality, the bottom of the water pipe 24 needs to be soaked in water for cleaning. The water pipe 24 extends into the filter assembly 5 and is connected to the fixed pipe assembly 7. The displacement assembly 4 includes a guide rail 41 opened on the outside of the enrichment device 21 and a shift frame 42 that slides in contact with the outside of the enrichment device 21. A slider 43 is fixed on the side of the shift frame 42 near the enrichment device 21. The shift frame 42 slides along the guide rail 41 through the slider 43, so that the shift frame 42 can move up and down linearly along the guide rail 41 on the outside of the enrichment device 21, thereby driving the detachable frame plate 3 and the filter assembly 5 to move downward, so that the filter assembly 5 comes into contact with the sampled water, and the two water pipes 24 can respectively perform enrichment treatment of the sampled water by suction and discharge.

[0059] Further, please refer to Figure 5The filter assembly 5 includes a housing 51 fixed to the bottom of the detachable frame plate 3, an inlet pipe 52 fixed to the top of the housing 51, a detection chamber opened in the housing 51, and a filter device installed in the detection chamber in a detachable manner. During enrichment treatment, the housing 51 drives the filter device to be immersed in the sampled water, and the pipette 24 moves down synchronously with the housing 51 under the fixation of the pipe fixing assembly 7, so that the pipette 24 also comes into contact with the sampled water in the housing 51, which facilitates the intake and discharge of the sampled water.

[0060] In practice, a container filled with sampled water and an empty container are placed directly below the two filter components 5. Then, when the two filter components 5 are moved down synchronously by the moving frame 42, the filter device at the water inlet can come into contact with the sampled water, and the sampled water is drawn out through the pipette 24. Then, the sampled water is discharged from the other pipette 24 into the empty container under the processing of the enrichment device 21, so that the components of the sampled water can be enriched in the filter device in the empty container, thus completing the enrichment operation of the sampled water.

[0061] Specifically, please refer to Figure 6 The detection chamber includes a top cavity 53, a transition cavity 54, and a filter cavity 55, which are sequentially opened from top to bottom inside the outer shell 51, to facilitate the filtration of the sampled water and to provide reasonable installation space for the pipette 24.

[0062] The filtration device includes a filter element 56 and a pop-out element 57 respectively installed in the filter chamber 55 and the transition chamber 54. The filter element 56 is fixed to the housing 51 by a locking element 58. The cooperation between the pop-out element 57 and the locking element 58 allows the filter element 56 to be quickly installed and removed in the housing 51, so as to facilitate removal after enrichment and quick installation in the housing 51 after cleaning or replacement.

[0063] Specifically, the filter element 56 includes a mounting frame 561 inserted inside the filter chamber 55, a filter membrane 562 fixed inside the mounting frame 561, and a sealing ring 563 fixed outside the mounting frame 561. The filter membranes 562 in the two filter elements 56 are made of different materials. The one at the water inlet is used for preliminary filtration of impurities in the water, while the one at the water outlet is used for filtering out heavy metals. Since this purpose and principle are common methods for heavy metal detection in existing water samples, they will not be described in detail here.

[0064] After heavy metals accumulate on the filter membrane 562 at the water outlet, the mounting frame 561 can be removed from the outer shell 51 and moved to the detector body 1 for heavy metal detection. The whole process only requires holding the upper part of the detachable frame plate 3 to move and pop out the mounting frame 561, so that the hand will not come into contact with the sampled water.

[0065] The sealing ring 563 is made of ABS plastic. The outer side of the mounting frame 561 is fitted with the transition cavity 54 through the sealing ring 563, so that the sealing ring 563 and the transition cavity 54 are tightly fitted to prevent the sampling water from seeping into the interior of the outer shell 51.

[0066] Specifically, please refer to Figure 7 The pop-out component 57 includes a telescopic ring 571 that slides in contact with the transition cavity 54 on the outside and a first spring 572 that is fixedly connected to the telescopic ring 571 at the bottom. The top of the first spring 572 is fixed to the transition cavity 54, and the bottom surface of the telescopic ring 571 abuts against the mounting frame 561. When the mounting frame 561 is installed inside the housing 51, the first spring 572 is in a compressed state, so that when the mounting frame 561 needs to be removed, the first spring 572 can pop the mounting frame 561 downward through the telescopic ring 571.

[0067] The sealing ring 563 has notches 564 on both sides. The locking member 58 includes an installation cavity 581 and a sliding groove 582 inside the outer shell 51. The installation cavity 581 and the sliding groove 582 are connected to each other. A locking block 583 is rotatably installed in the installation cavity 581. The end of the locking block 583 near the filter cavity 55 is engaged with the sealing ring 563 through the notch 564. That is, the inner end of the locking block 583 abuts against the upper part of the notch 564 of the sealing ring 563, so that the installation frame 561 can be stably inserted into the filter cavity 55.

[0068] An electromagnetic component 584 is fixedly installed inside the mounting cavity 581. The electromagnetic component 584 is a commonly used electromagnetic generating component. A telescopic block 585 is slidably installed inside the slide groove 582. The telescopic block 585 can slide up and down linearly along the slide groove 582. A magnetic block 586 is fixedly installed at the top of the telescopic block 585 for cooperating with the electromagnetic component 584. When the electromagnetic component 584 is energized, it will generate a repulsive force on the magnetic block 586, causing the magnetic block 586 to drive the telescopic block 585 to move downward. The outer side of the telescopic block 585... A first push groove 587 is provided, and the telescopic block 585 abuts against the other end of the locking block 583 through the first push groove 587, so that when the telescopic block 585 moves downward, it can apply force to the locking block 583 through the first push groove 587, so that the locking block 583 can stably apply force to fasten the sealing ring 563. A compression spring 588 is fixedly provided in the slide groove 582 to provide telescopic elastic force for the telescopic block 585. The upper and lower ends of the compression spring 588 are fixedly connected to the telescopic block 585 and the slide groove 582 respectively.

[0069] When the electromagnetic component 584 is de-energized, the telescopic block 585 moves upward via the compression spring 588, causing the locking block 583 to rotate clockwise. This causes the inner end of the locking block 583 to move out of the notch 564, allowing the mounting frame 561 to pop out of the outer shell 51 under the elastic force of the telescopic ring 571. When the mounting frame 561 needs to be installed, by holding the detachable frame plate 3, aligning the filter chamber 55 with the mounting frame 561, the mounting frame 561 can be pressed into the filter chamber 55. Then, the electromagnetic component 584 is energized, causing the locking block 583 to return to its original position and lock the notch 564.

[0070] Further, please refer to Figure 8 The loading and unloading assembly 6 includes a plug assembly and a force-bearing panel that are detachably connected to each other. The plug assembly is used to connect to the detachable frame plate 3, while the force-bearing panel is installed on the moving frame 42, so that the detachable frame plate 3 can be quickly separated from the moving frame 42 when the mounting frame 561 needs to be moved to the detector body 1, and can be returned to its original position after the operation is completed.

[0071] Specifically, the insert assembly includes an insert 61 fixed to the detachable frame plate 3 on one side, a locking cavity 62 opened on the side of the insert 61 away from the detachable frame plate 3, a locking block 63 fixed in the locking cavity 62, and a magnetic plate 64. The vertical cross section of the insert 61 is square. The number of locking cavities 62 is four equidistantly arranged on the outside of the insert 61. The surface of the locking block 63 is provided with two symmetrically distributed inclined surfaces 65 to facilitate the connection of the locking block 63 to the force-bearing panel through the inclined surfaces 65.

[0072] Please refer to Figure 9 The force-bearing panel includes a force-bearing plate 66 fixedly connected to the outer side of the transfer frame 42, a slot 67 and a telescopic groove 68 formed in the force-bearing plate 66, and a magnetic bead 69 slidably installed in the telescopic groove 68. The magnetic bead 69 is fixedly connected to the inner end of the telescopic groove 68 by a second spring 610. The magnetic bead 69 can only move within the telescopic groove 68. The side of the magnetic bead 69 away from the slot 67 falls into the upward vertical projection range of the telescopic groove 68, so that the inner end of the magnetic bead 69 can be partially moved into the slot 67. The outer side of the insert block 61 is inserted into the slot 67. The locking cavity 62 is magnetically connected to the magnetic bead 69 via the magnetic plate 64. After the surface of the magnetic bead 69 passes over the inclined surface 65, it is inserted into the locking cavity 62. When the insert block 61 is inserted into the slot 67, the locking block 63 can squeeze the magnetic bead 69 through the inclined surface 65, causing the magnetic bead 69 to retract into the telescopic groove 68. After the locking block 63 continues to move in, the magnetic bead 69 can move from another inclined surface 65 into the locking cavity 62 by the elastic force of the second spring 610, and magnetically connect with the magnetic plate 64, thereby allowing the insert block 61 to be stably inserted into the slot 67.

[0073] Further, please refer to Figure 10After the water pipe 24 extends into the inlet pipe 52, it connects with the fixed pipe assembly 7. When the outer shell 51 moves down, it can drive the bottom end of the straw 24 to move down synchronously, so as to facilitate bringing the bottom end of the straw 24 into the container. The surface of the detachable frame plate 3 is provided with a sliding opening 31, and the interior of the detachable frame plate 3 is provided with a through groove 32 and an installation groove 33 communicating with the sliding opening 31. The fixed pipe assembly 7 includes a drive assembly 71 slidably disposed in the through groove 32, a clamping assembly 72 abutting against the outside of the water pipe 24, and a tightening assembly 73 connected to the drive assembly 71. The clamping assembly 72 applies force to fix the water pipe 24, and the tightening assembly 73 controls the clamping state of the clamping assembly 72 to facilitate loading and unloading of the straw 24.

[0074] Specifically, please refer to Figure 10 and Figure 11 The drive assembly 71 includes a push plate 711 that slides in contact with the through groove 32 on its outer side, a finger block 712 fixed on the outer side of the push plate 711, and a third spring 713 that is fixed at both ends to the through groove 32 and the push plate 711 respectively. The third spring 713 provides a return force to the push plate 711. The outer end of the finger block 712 extends out of the sliding opening 31 to facilitate the finger to push the finger block 712 downward so that the push plate 711 slides downward.

[0075] Please refer to Figure 11 The clamping assembly 72 includes clamping arms 721 symmetrically arranged on the outside of the water pipe 24, an arc plate 722 fixed to one end of the clamping arm 721, a shaft 723 fixedly connected to the bottom end of the clamping arm 721, and a bracket 724 fixed in the top cavity 53. The outside of the shaft 723 is rotatably connected to the bracket 724. A first coil spring 725 is fixedly installed on the bracket 724 to help the shaft 723 rotate back to its original position. When the clamping arm 721 rotates on the bracket 724 through the shaft 723, it can be reset by the first coil spring 725. In normal condition, the arc plates 722 on the two clamping arms 721 abut against each other under the drive of the first coil spring 725. The inner side of the arc plate 722 abuts against the water pipe 24, thereby clamping the outside of the water pipe 24 through the arc plate 722, so that the water pipe 24 can keep synchronized with the up and down movement of the outer shell 51 after it is inserted into the outer shell 51.

[0076] In implementation, the bottom end of the push plate 711 is provided with a first ramp 714, and the other end of the clamping arm 721 slides into the mounting groove 33 and is rotatably mounted with a pulley 726. The tensioning component 73 includes a drive block 731 set in the mounting groove 33, a second ramp 732 symmetrically opened on the outside of the drive block 731, and a second push groove 733 penetrating the upper and lower surfaces of the drive block 731. The push plate 711 slides in contact with the second push groove 733 through the first ramp 714, so that when the push plate 711 moves down, it can apply force to the second push groove 733 through the push plate 711, thereby causing the drive block 731 to move away from the clamping arm 721. The clamping arm 721 rotates in contact with the second ramp 732 through the pulley 726. The outside of the drive block 731 is fixed to the mounting groove 33 by a fourth spring 734. A support cylinder 735 is fixed on the outside of the drive block 731, and the inside of the support cylinder 735 is slidably connected to the guide rod 736.

[0077] The drive block 731 can be kept vertically sliding away from or close to the clamping arm 721 by the support cylinder 735. When it is necessary to remove the water pipe 24, simply press down the push plate 711 to move the drive block 731 away from the clamping arm 721, so that the arc plates 722 on the clamping arm 721 move away from each other, thereby separating from the water pipe 24. Before the water pipe 24 extends into the outer shell 51, the arc plates 722 are moved away from each other in the same way, and then the force applied to the push plate 711 is released, so that the arc plates 722 abut against the outer wall of the water pipe 24 and can be fixed in place inside the outer shell 51.

[0078] Further, please refer to Figure 12 The return component 8 includes a recycling cylinder and a return button. When the moving frame 42 moves down, the moving frame 42 is automatically recycled through the recycling cylinder, and the recycling cylinder is controlled by operating the return button.

[0079] Specifically, the recycling cylinder includes a protective cylinder 811 fixedly connected to the enrichment device 21 on the outside, a spiral tube 812 rotatably installed inside the protective cylinder 811, two limiting discs 813 fixed at intervals on the outside of the spiral tube 812, and a winding rope 814 wound on the spiral tube 812. The top end of the winding rope 814 is fixed to the spiral tube 812 and then wound. The two limiting discs 813 limit the winding range of the winding rope 814 on the spiral tube 812. The bottom end of the winding rope 814 slides out of the protective cylinder 811 and is fixed to the transfer frame 42. This allows the spiral tube 812 to be rotated by the winding rope 814 when the transfer frame 42 moves down. A second coil spring 815 for rotation return is installed on the outside of the spiral tube 812. When the spiral tube 812 needs to be reset, the second coil spring 815 can drive the spiral tube 812 to return to its original position, thereby causing the spiral tube 812 to wind up the winding rope 814 and drive the transfer frame 42 to move up.

[0080] Please refer to Figure 12 and Figure 13The return button includes a button 821 slidably mounted on the protective cylinder 811, a pressure tube 822 fixed at one end when the button 821 moves into the protective cylinder 811, and a fifth spring 823 fixed at both ends to the pressure tube 822 and the protective cylinder 811 respectively. The button 821 can only slide on the protective cylinder 811. When the button 821 is pressed, it will drive the pressure tube 822 to push inside the protective cylinder 811 and reset through the fifth spring 823.

[0081] The inner side of the spiral tube 812 is provided with a toothed groove 816, and the outer wall of the pressure tube 822 is fixed with a movable disk 824. A clamp 825 is rotatably mounted on the movable disk 824. The outer end of the clamp 825 abuts against the toothed groove 816. When it is necessary to move the shifting frame 42 down, thereby moving the detachable frame plate 3 down, the shifting frame 42 can be pressed down directly, causing the shifting frame 42 to pull the winding rope 814, causing the spiral tube 812 to rotate, and causing the toothed groove 816 to rotate synchronously. Under the blocking of the clamp 825, the toothed groove 816 cannot return to its original position under the action of the second coil spring 815, so that the spiral tube... If tube 812 cannot return to its original position, when tube 812 needs to return to its original position, simply press button 821 to cause moving disk 824 to drive card holder 825 to misalign with tooth groove 816, thereby causing tube 812 to automatically rotate and reset, pulling moving frame 42 to move upward automatically. A spring plate 826 is installed between moving disk 824 and card holder 825, which provides reset elasticity to card holder 825 so that card holder 825 can continuously reset with tooth groove 816. After completion, press button 821 can be reset by the fifth spring 823, so that card holder 825 returns to its original position.

[0082] It is worth noting that a control module 34 is embedded in the detachable frame plate 3. The control module 34 includes a switch and a power supply module. The power supply module is used to supply power to the electromagnetic component 584 and controls the opening and closing of the electromagnetic component 854 by pressing the switch.

[0083] The control method of this invention is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
