Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic detection and elimination equipment, in particular to a portable electrostatic detection and elimination device for geophysical prospecting operations. Background Technique

[0002] At present, the acquisition of seismic data in oilfield development mostly uses the excitation method of combining detonators and explosives with drilling and filling. In the explosive-related operations (the operation links of explosives and detonators), the amount of static electricity carried by the operators determines the safety of the explosive-related links. Each explosive-packing worker needs to be equipped with tools such as a special detonator test meter, a special detonator box, and an electrostatic discharge rod. In the explosive-related operation links, the electrostatic discharge rod usually does not have the functions of detecting the static electricity margin and measuring the grounding resistance, and cannot safely and effectively ensure that all the static electricity of the explosive-related personnel is released before the explosive-related operations, thus there are potential risks and hidden dangers in the explosive-related operations.

[0003] In this regard, it can be known from the retrieval of the novelty search agency that the patent publication number CN206745747U discloses a portable electrostatic detection and elimination device for geophysical prospecting operations, including a conductive tube inserted into the ground, a support frame fixed on the conductive tube, and a diode static electricity margin indicator electrically connected to the conductive tube. The support frame is used to place a resistance tester. A touchable metal conductive part is provided on the diode static electricity margin indicator. When touching the metal conductive part, when there is static electricity on the human body, the diode static electricity margin indicator emits light to prompt. When the static electricity is released, the diode static electricity margin indicator no longer emits light, thereby ensuring the reliable grounding of the conductive tube and the reliable release of static electricity, and improving the safety of the explosive-related links.

[0004] The above-mentioned disclosed portable electrostatic detection and elimination device for geophysical prospecting operations can measure the grounding resistance by using a resistance tester, detect static electricity by observing whether the diode static electricity margin indicator emits light when a person touches the metal conductive part at the top of the diode static electricity margin indicator, and eliminate static electricity through touch conduction. However, there are still the following deficiencies in use: 1. (It realizes the support for the resistance tester by fixing a support frame on one side of the conductive rod, and fixes a wire winding hook at the bottom of the support frame to facilitate the winding and support of the cable of the resistance tester by personnel), but there is no structure for folding the support frame and the wire winding hook integrally after use. The support frame and the wire winding hook directly protrude from the right side of the conductive rod in a large area, occupying a large space and being inconvenient for convenient carrying work. In view of this, in view of the above deficiencies, improvements are made on this basis, and the present application proposes a portable electrostatic detection and elimination device for geophysical prospecting operations.

Specific implementation manner

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0026] As Figures 1 to 5 shown, the portable static electricity detection and elimination device proposed in this embodiment includes a portable static electricity detection and elimination device body. The portable static electricity detection and elimination device body includes a conductive rod 1 for inserting into the ground, a diode static electricity margin indicator light 101 fixed at the top of the conductive rod 1, and a probe insertion hole 102 opened on the front side of the conductive rod 1. The metal pins of the diode static electricity margin indicator light 101 are fixedly connected to the top of the conductive rod 1. A support plate 2 for placing a resistance tester is arranged on the right side of the conductive rod 1, and a wire winding hook 3 for winding the cable of the resistance tester is arranged below the support plate 2; among them, the other specific composition structures of the portable static electricity detection and elimination device body, and the principle of static electricity detection and elimination after one probe of the resistance tester is inserted into the probe insertion hole 102 and the other probe is inserted a specified distance below the ground and then the body contacts the metal conductive part on the upper part of the diode static electricity margin indicator light 101 itself are prior arts. In addition, this composition and technology have also been disclosed in the above-mentioned prior art CN206745747U and are the same as it, so no further elaboration will be made here;

[0027] On the right side of the conductive rod 1, a U-shaped seat 4 is fixedly connected. Between the front and rear inner walls of the U-shaped seat 4, a rotating seat 5 is rotatably connected. Among them, a pin shaft is fixedly connected between the front and rear inner walls of the U-shaped seat 4. A circular through hole is opened on the front side of the rotating seat 5. A first bearing is fixedly sleeved in the circular through hole. The inner ring of the first bearing is fixedly sleeved on the outer side of the pin shaft, achieving the effect of rotatably installing the rotating seat 5. The right side of the rotating seat 5 is fixedly connected to the left side of the support plate 2. Card slots 6 are opened on the left side and the bottom of the rotating seat 5. An elastic and convenient clamping and fixing component is movably clamped in the card slot 6 located on the left side. The conductive rod 1 is fixedly sleeved on the elastic and convenient clamping and fixing component. The elastic and convenient clamping and fixing component is used to conveniently clamp, lock, and unlock the rotating seat 5 through the card slot 6. The locked rotating seat 5 is used to support the support plate 2. When the support plate 2 is rotated downward after unlocking, the rotating seat 5 is driven to rotate downward, achieving the effect of folding the support plate 2 downward to reduce the occupied space when the support plate 2 is not in use;

[0028] A rectangular groove 11 with an open right side is opened at the bottom of the support plate 2. The lower left corner of the wire winding hook 3 is rotatably connected with a pressing wheel 15 that cooperates with the right side of the conductive rod 1. Among them, a groove with an open bottom is opened on the left bottom side of the wire winding hook 3. The left side of the pressing wheel 15 protrudes from the left side of the wire winding hook 3. A round shaft is fixedly connected between the front and rear inner walls of the groove. A circular through hole is provided on the front side of the pressing wheel 15. A second bearing is fixedly sleeved in the circular through hole. The inner ring of the second bearing is fixedly sleeved on the outer side of the round shaft, achieving the effect of rotatably installing the pressing wheel 15, so that the pressing wheel 15 is rotatably installed between the front and rear inner walls of the groove. A self-folding and pop-up elastic rotating support component is installed between the front and rear inner walls of the rectangular groove 11. The bottom of the self-folding and pop-up elastic rotating support component is fixedly connected to the top of the wire winding hook 3. When the support plate 2 rotates downward and folds, driving the wire winding hook 3 to rotate downward, the wire winding hook 3 drives the pressing wheel 15 to press against the right side of the conductive rod 1. The self-folding and pop-up elastic rotating support component is used to allow the wire winding hook 3 to rotate and fold into the rectangular groove 11 when the pressing wheel 15 presses against the conductive rod 1, and is used to automatically drive the wire winding hook 3 to rotate out for use when the support plate 2 rotates out, achieving the effect of automatically folding the wire winding hook 3 integrally when the support plate 2 folds.

[0029] Specifically, the elastic and convenient clamping component includes a T-shaped clamping rod 9 movably clamped in the clamping groove 6 on the left side. A U-shaped seat 4 is slidably sleeved on the T-shaped clamping rod 9. An outer tube 7 with a plugging structure at the left end is slidably sleeved on the T-shaped clamping rod 9. Transverse guide holes for slidably sleeving the outer side of the T-shaped clamping rod 9 are provided on the left side of the U-shaped seat 4 and the left end of the outer tube 7, which serves to allow the T-shaped clamping rod 9 to pass through and guide its lateral sliding. A conductive rod 1 is fixedly sleeved on the outer tube 7. A sleeve hole fixedly connected to the outer side of the outer tube 7 is provided on the right side of the conductive rod 1. A pressure block 8 is slidably sleeved in the outer tube 7. The pressure block 8 is fixedly sleeved on the T-shaped clamping rod 9. A spring 10 is fixedly connected between the left side of the pressure block 8 and the inner wall of the left end of the outer tube 7. The spring 10 is movably sleeved on the T-shaped clamping rod 9. The arranged T-shaped clamping rod 9, outer tube 7, pressure block 8 and spring 10 cooperate. By using the clamping of the T-shaped clamping rod 9 and the clamping groove 6, the rotation seat 5 is clamped and locked. Pull the T-shaped clamping rod 9 to the left to drive the pressure block 8 to compress the spring 10 to the left. The T-shaped clamping rod 9 separates from the clamping groove 6 on the left side, realizing convenient pulling and unlocking. Then the support plate 2 can be rotated downward and folded to drive the rotation seat 5 to rotate downward. After folding, release the pulling force on the T-shaped clamping rod 9. The elastic force of the spring 10 in the compressed state drives the T-shaped clamping rod 9 to the right to be clamped into the originally lower clamping groove 6, realizing the locking after folding. In addition, after pulling and unlocking again, the support plate 2 can also be rotated upward and opened and the clamping work can be carried out again.

[0030] Furthermore, the self-folding and pop-up elastic rotating support assembly includes a support shaft 12 rotatably connected between the front and rear inner walls of the rectangular groove 11. Third bearings are fixedly connected to both the front and rear inner walls of the rectangular groove 11. The inner ring of the third bearing is fixedly sleeved on the outer side of the support shaft 12, achieving the effect of rotatably mounting the support shaft 12. A rotating sleeve 13 fixedly connected to the top end of the wire winding hook 3 is fixedly sleeved on the support shaft 12. A torsion spring 14 is fixedly connected between the front side of the rotating sleeve 13 and the front inner wall of the rectangular groove 11. The torsion spring 14 is movably sleeved on the support shaft 12. A limiting block 16 is fixedly connected to the top of the rotating sleeve 13. The right side of the limiting block 16 is in movable contact with a stop block, and the top of the stop block is fixedly connected to the top inner wall of the rectangular groove 11, achieving the effect of limiting the clockwise rotation stroke of the rotating sleeve 13. The arranged support shaft 12, rotating sleeve 13, and torsion spring 14 cooperate. When the support plate 2 rotates and folds and drives the pressing wheel 15 to press against the right side of the conductive rod 1 through the wire winding hook 3, it is blocked and restricted. The support plate 2 that continues to rotate downward rotates at both ends of the support shaft 12 and twists and stores energy in the torsion spring 14. As the support plate 2 continues to rotate downward, the support plate 2 drives the rectangular groove 11 to be sleeved on the wire winding hook 3, achieving the effect of automatically folding the wire winding hook 3 integrally when the support plate 2 folds, further reducing the occupied space. When the support plate 2 is subsequently rotated and opened, the elastic force of the torsion spring 14 that rotates by using the stored energy drives the rotating sleeve 13 to rotate back. The rotating sleeve 13 drives the wire winding hook 3 to automatically rotate downward. The method of folding or rotating out the wire winding hook 3 integrally when the support plate 2 is folded out does not require personnel to operate the wire winding hook 3 separately, improving the operation convenience.

[0031] The usage method of this embodiment is as follows: When the portable electrostatic detection and elimination device for geophysical exploration operations is in use, after inserting the conductive rod 1 into the ground specified in the geophysical exploration site, the other specific component structures of the portable electrostatic detection and elimination device body, and after one probe of the resistance tester is inserted into the probe insertion hole 102 and the other probe is inserted below the ground at a specified distance, the principle of electrostatic detection and elimination after the body contacts the metal conductive part on the upper part of the diode static electricity margin indicator 101 is prior art. In addition, this composition and technology have also been disclosed in the above prior art CN206745747U and are the same, so no further elaboration will be made here.

[0032] When in use, the support plate 2 is used to support the resistance tester, and the wire winding hook 3 is used for personnel to wind the cable of the resistance tester to prevent the phenomenon of long and messy cables. After using and taking away the resistance tester, pull the T-shaped clamping rod 9 to the left to drive the pressing block 8 to compress the spring 10 to the left. The T-shaped clamping rod 9 separates from the clamping groove 6 on the left, realizing convenient pulling and unlocking. At this time, rotate the support plate 2 downward and fold it to the right side of the conductive rod 1. When the support plate 2 folds, it drives the rotating seat 5 to rotate downward, and the rotating seat 5 drives the two clamping grooves 6 to rotate, so that the clamping groove 6 originally at the lower part rotates to the left. At this time, relax the pulling force on the T-shaped clamping rod 9, and the elastic force of the spring 10 in the compressed state drives the T-shaped clamping rod 9 to the right and snap into the aligned clamping groove 6, realizing the locking after folding, making it convenient to fold the support plate 2 quickly and conveniently after use and reducing the occupied space on the right side; when the support plate 2 rotates downward and folds, it also drives the wire winding hook 3 to rotate downward. When the wire winding hook 3 drives the extrusion wheel 15 to rotate and squeeze against the right side of the conductive rod 1, it is blocked and restricted by it. The continuously downward rotating support plate 2 rotates at both ends of the support shaft 12 and twists and stores energy for the torsion spring 14. As the support plate 2 continues to rotate downward, the support plate 2 drives the rectangular groove 11 to be sleeved on the wire winding hook 3, realizing the effect of automatically folding the wire winding hook 3 integrally when the support plate 2 folds, further reducing the occupied space, making it convenient to fold the support plate 2 and the wire winding hook 3 integrally, quickly and conveniently after use, effectively reducing the occupied space on the right side when not in use, and facilitating the convenient carrying work for personnel;

[0033] When unlocking by separating the T-shaped clamping rod 9 from the clamping groove 6 again later, the personnel can rotate the support plate 2 upward and turn it over, and then can use the T-shaped clamping rod 9 for clamping work again. When the support plate 2 is turned over, the elastic force of the torsion spring 14 in the state of torsion and energy storage drives the rotating sleeve 13 to rotate, and the rotating sleeve 13 drives the wire winding hook 3 to automatically rotate downward, realizing the effect of turning out the support plate 2 and the wire winding hook 3 integrally. By using the method of folding or turning out the support plate 2 and the wire winding hook 3 integrally, there is no need for personnel to operate the wire winding hook 3 separately, improving the operation convenience.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
