Description

Technical Field

[0001] This utility model relates to the field of seismic exploration equipment technology; more specifically, it relates to a seismic exploration borehole anti-collapse device. Background Technology

[0002] Seismic exploration borehole anti-collapse devices are safety devices used to ensure that boreholes do not collapse or crumble under blasting and pressure during seismic exploration. Their main functions are to enhance the structural stability of the borehole, protect the safety of workers, and ensure the accuracy of exploration data.

[0003] Currently, existing seismic exploration borehole anti-collapse devices typically support a fixed borehole outer diameter. When different seismic exploration conditions require different sizes of anti-collapse devices, the application range is limited. Furthermore, carrying multiple sizes of anti-collapse devices during seismic exploration is inconvenient and reduces the device's practicality. Additionally, the original anti-collapse device typically supports a fixed depth for boreholes of varying depths, making adjustment difficult and further reducing applicability. Therefore, a seismic exploration borehole anti-collapse device is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seismic exploration borehole anti-collapse device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a seismic exploration borehole anti-collapse device, comprising:

[0006] The base plate has an adjustment structure inside, and a splicing plate is provided at the top of the adjustment structure. A connecting plate is fixedly connected inside the splicing plate. An extension structure is provided inside the connecting plate. Connecting rods are fixedly connected to both sides of the top of the base plate and the connecting plate. Positioning grooves are provided at the top of both sides of the outer surface of the connecting rods. A connecting structure is provided at the bottom of the base plate and the connecting plate.

[0007] The adjustment structure includes a drive motor, and the drive motor is mounted on the top surface of the base plate;

[0008] The extension structure includes an extension groove, and the extension groove is formed inside the connecting plate.

[0009] The connection structure includes a fixing plate, and the fixing plate is provided in two sets, with the two sets of fixing plates respectively fixed to the bottom surface of the base plate and the bottom surface of the connecting plate.

[0010] Preferably, the adjustment structure further includes a movable groove, which is located inside the base plate. The output shaft of the drive motor is connected to a first bevel gear via a bearing. The movable groove contains a second bevel gear that meshes with the first bevel gear. There are two sets of the second bevel gears. A lead screw is fixedly connected to one side of each set of the second bevel gears. A movable plate is threaded onto the outer surface of the lead screw. A support plate is fixedly connected to one end of the movable plate. The support plate has an arc-shaped design, which allows for adjustment of the movement distance of the support plates on both sides.

[0011] Preferably, a support block is fixedly connected at the middle position inside the movable groove, and both sides of the support block are fixedly connected to the second bevel gear through a rotating shaft. The internal dimensions of the movable groove are adapted to the external dimensions of the movable plate. This design can support the two sets of second bevel gears, so that the second bevel gear and the first bevel gear always remain in a meshing state.

[0012] Preferably, the extension structure further includes extension plates, and there are two sets of extension plates. The two sets of extension plates are respectively inserted into the inner sides of the extension groove. One end of the extension plate is fixedly connected to the splicing plate, and the other end of the extension plate is fixedly connected to a limiting plate. Limiting grooves are opened at both the upper and lower ends of the extension groove, and the width of the limiting groove is the same as the width of the limiting plate. This design allows the two sets of extension plates to extend when the splicing plate moves.

[0013] Preferably, the connection structure further includes an insertion slot, and there are two sets of insertion slots. The two sets of insertion slots are respectively opened on both sides of the bottom surface of the fixing plate. The inner sides of the insertion slot are provided with grooves, and springs are provided inside the grooves. One end of the spring is provided with a locking block. The outer surface of the locking block is trapezoidal, and the outer dimensions of the locking block are adapted to the inner dimensions of the positioning slot. This design can play a positioning role for the connecting rod.

[0014] Preferably, one end of the spring is fixedly connected to a limiting circular plate, and the external dimensions of the limiting circular plate are adapted to the internal dimensions of the groove. This design makes the movement of the locking block more stable.

[0015] The technical effects and advantages of this utility model are as follows: By starting the drive motor, the first bevel gear can be rotated. Because the second bevel gear meshes with the first bevel gear, it can drive two sets of second bevel gears to rotate in opposite directions simultaneously. This causes the two sets of lead screws to rotate accordingly, and drives the movable plate and support plate to move until the two sets of support plates respectively contact the inner wall of the blast hole, at which point the drive motor stops. This design allows the spacing between the two sets of support plates to be adjusted according to the blast hole of different outer diameters, so that the equipment as a whole can adapt to blast holes of various outer diameters, thus enhancing the range of applications of the equipment. At the same time, during seismic exploration, there is no need to carry multiple blast hole anti-collapse devices of various sizes, making it more convenient to use and improving the practicality of the equipment to a certain extent.

[0016] By placing the splicing plate above the adjustment structure and inserting the two sets of connecting rods into the insertion slots, when the thrust is greater than the spring force, the outer surface of the connecting rod moves against the inclined surface of the locking block, pressing the locking blocks on both sides back into the groove until the locking blocks on both sides move back to a certain position, allowing the connecting rod to be inserted into the top position of the insertion slot. At this point, under the action of the spring force, the locking block can be ejected outward and locked into the positioning groove. This design allows for splicing operations between the base plate and the splicing plate equipment, enabling it to be used according to the hole depth when facing blast holes of different depths, thereby improving the applicability of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The seismic exploration equipment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-6 As shown in the figure, this embodiment proposes a seismic exploration borehole anti-collapse device, comprising:

[0029] The base plate 1 has an adjustment structure 2 inside, and a splicing plate 3 is provided at the top of the adjustment structure 2. A connecting plate 4 is fixedly connected inside the splicing plate 3. An extension structure 5 is provided inside the connecting plate 4. Connecting rods 6 are fixedly connected to both sides of the top of the base plate 1 and the connecting plate 4. Positioning grooves 7 are provided on both sides of the top of the outer surface of the connecting rods 6. A connecting structure 8 is provided at the bottom of the base plate 1 and the connecting plate 4.

[0030] The adjustment structure 2 includes a drive motor 21, which is mounted on the top surface of the base plate 1. The adjustment structure 2 also includes a movable groove 22, which is located inside the base plate 1. The output shaft of the drive motor 21 is connected to a first bevel gear 23 by a bearing. The movable groove 22 is provided with a second bevel gear 24 that meshes with the first bevel gear 23. There are two sets of the second bevel gear 24. A lead screw 25 is fixedly connected to one side of each set of the second bevel gear 24. A movable plate 26 is threadedly connected to the outer surface of the lead screw 25. A support plate 27 is fixedly connected to one end of the movable plate 26. The support plate 27 has an arc-shaped design, which can enhance the contact area between the support plate 27 and the inner wall of the borehole and better prevent the borehole from collapsing.

[0031] A support block is fixedly connected to the middle position inside the movable groove 22, and both sides of the support block are fixedly connected to the second bevel gear 24 through a rotating shaft. The internal dimensions of the movable groove 22 are adapted to the external dimensions of the movable plate 26. This design can support the two sets of second bevel gears 24, so that the two sets of second bevel gears 24 always maintain meshing with the first bevel gear 23.

[0032] The extension structure 5 includes an extension groove 51, which is located inside the connecting plate 4. The extension structure 5 also includes an extension plate 52, which is provided in two sets. The two sets of extension plates 52 are respectively inserted into the inside of the extension groove 51 on both sides. One end of the extension plate 52 is fixedly connected to the splicing plate 3, and the other end of the extension plate 52 is fixedly connected to the limiting plate 53. The upper and lower ends of the extension groove 51 are provided with limiting grooves 54, and the width of the limiting groove 54 is the same as the width of the limiting plate 53. This design can effectively prevent the extension plate 52 from moving out of the inside of the extension groove 51 under the action of the limiting plate 53.

[0033] Example 2

[0034] like Figure 7 and Figure 8 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0035] The connecting structure 8 includes a fixing plate 81, and there are two sets of fixing plates 81. The two sets of fixing plates 81 are respectively fixed to the bottom surface of the base plate 1 and the bottom surface of the connecting plate 4. The connecting structure 8 also includes an insertion slot 82, and there are two sets of insertion slots 82. The two sets of insertion slots 82 are respectively opened on both sides of the bottom surface of the fixing plate 81. The two sides of the insertion slot 82 are provided with grooves 83, and springs 84 are provided inside the grooves 83. A locking block 85 is provided at one end of the spring 84. The outer surface of the locking block 85 is trapezoidal, and the outer dimensions of the locking block 85 are adapted to the inner dimensions of the positioning groove 7. Under the elastic action of the spring 84, the locking block 85 can be popped outward. When the locking block 85 is inserted into the interior of the positioning groove 7, the connecting rod 6 can be positioned.

[0036] One end of the spring 84 is fixedly connected to a limiting circular plate, and the outer dimensions of the limiting circular plate are adapted to the inner dimensions of the groove 83. This design allows the locking block 85 to move smoothly.

[0037] Working principle: When using the equipment, first observe the depth of the borehole, then place the splicing plate 3 above the adjusting structure 2, and insert the two sets of connecting rods 6 into the insertion slots 82 respectively. At this time, when the thrust is greater than the elastic force of the spring 84, the outer surface of the connecting rod 6 can move against the inclined surface of the locking block 85, and press the locking blocks 85 on both sides to move back into the groove 83 until the locking blocks 85 on both sides move back to a certain position, so that the connecting rod 6 can be inserted into the top position of the insertion slot 82. At this time, under the elastic force of the spring 84, the locking blocks 85 can be pushed outward. The splicing plate 3 is ejected from the side and inserted into the positioning groove 7. This allows the splicing plate 3 to be positioned at the upper end of the base plate 1. Then, another set of splicing plates 3 is taken and the connecting rod 6 of the other set of splicing plates 3 is inserted into the insertion groove 82 at the bottom of the base plate 1. The above operation is repeated to position the two sets of splicing plates 3 at the upper and lower ends of the base plate 1 respectively. Depending on the depth, the splicing plates 3 can be spliced ​​together again, so that the equipment as a whole can adapt to blast holes of various depths, enhancing its applicability. At the same time, it increases the contact area between the equipment and the inner wall of the blast hole, which can prevent the blast hole from collapsing to the greatest extent.

[0038] When using the equipment, the explosive is first placed into the bottom of the borehole. After the base plate 1 and the multiple sets of splicing plates 3 are spliced ​​together, the whole unit is placed into the borehole. By starting the drive motor 21, the first bevel gear 23 can be driven to rotate. Since the second bevel gear 24 meshes with the first bevel gear 23, it can drive the two sets of second bevel gears 24 to rotate in opposite directions at the same time, so that the two sets of lead screws 25 rotate accordingly, and drive the two movable plates 26 on both sides to move outward synchronously until the two sets of support plates 27 respectively touch the inner wall of the borehole. Then the drive motor 21 is stopped. At this time, it can be used according to the borehole with different diameters. The above is the complete working principle of this utility model.

[0039] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

[0040] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0041] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
