Description

Technical Field

[0001] This utility model relates to the field of seismic exploration technology, specifically a detector embedding coupling effect measurement device. Background Technology

[0002] In seismic exploration, the coupling effect between the geophone and the surface plays a crucial role in the accuracy of data acquisition. Currently, commonly used methods for measuring geophone coupling rely heavily on complex electronic sensors and data analysis systems, resulting in high equipment costs and cumbersome operation. Some simplified measurement methods cannot intuitively and quickly reflect the coupling state between the geophone and the surface, making it difficult for personnel to assess the geophone's installation quality on-site, thus affecting the overall efficiency and data quality of seismic exploration.

[0003] Announcement No. CN220709362U discloses a novel detector capable of automatically detecting coupling effects, comprising a device housing, an internal sensor disposed inside the device housing, a level sensor and a buzzer disposed inside the device housing, a depth sensor disposed at the bottom of the device housing, and a through groove formed at the center of the device housing, wherein a pressing block is installed in the through groove, the lower end of the pressing block is connected to an external expansion fixing component, and the lower end of the expansion fixing component is connected to a telescopic insertion cone component.

[0004] This existing technology is highly integrated and cannot be used with existing detectors.

[0005] Announcement No. CN216485539U discloses a geophone coupling device for a coal roadway. During the insertion of the geophone tail cone into the borehole, a square magnet attracts a fixed iron plate, firmly adhering the iron plate to the magnet. This pushes the geophone tail cone into the borehole, improving coupling between the tail cone and the coal roadway. Furthermore, the geophone will not loosen or fall off when vibrations occur in the coal roadway, and disassembly is easier. By installing a tail cone sleeve inside the borehole and providing elastic barbs on its exterior, the sleeve expands as the tail cone is continuously inserted, pushing outwards against the elastic barbs. These barbs then compress against the borehole wall, making the sleeve more securely installed and increasing the difficulty of detaching it from the borehole.

[0006] The existing technology requires the fixing plate to be connected to the detector body, which cannot accommodate detector bodies of various sizes.

[0007] Announcement No. CN220526020U discloses a nodal detector coupling quantitative detection instrument, including a housing, in which a tension sensor is installed. The tension sensor includes a fixed end and a movable end. The fixed end is used to be fixedly connected to the housing, and the movable end is used to pull the tension sensor to deform it relative to the pulling direction after it is connected to the nodal detector. A processing module is provided in the housing, and the processing module is connected to the tension sensor through a cable. The processing module is connected to a display module that converts the signal of the tension sensor into a tension value for display on the housing.

[0008] The existing technology and equipment are expensive.

[0009] In summary, the technical solutions, technical problems to be solved, and beneficial effects of the above-disclosed technologies are all different from those of this utility model. For more technical features, technical problems to be solved, and beneficial effects of this utility model, the above-disclosed technical documents do not provide any technical inspiration.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Example 1:

[0040] Please see Figures 1 to 5This utility model provides a detector embedding coupling effect measurement device, including a tension measuring component 1 and a fixing component 3. The fixing component 3 is used to fix the detector body 4. The fixing component 3 includes a fixing plate 31, and a fixing bolt 37 is provided through the fixing plate 31 for connecting to the ground. The fixing plate 31 is provided with a tail cone through hole. At least two symmetrically distributed clamping units are provided on the upper end surface of the fixing plate 31 around the tail cone through hole. The fixing plate 31 is connected to the ground by the fixing bolt 37. The tail cone 5 of the detector is coupled to the ground by passing through the tail cone through hole. The detector body 4 is clamped by the clamping units to complete the fixing of the detector body 4. The coupling force is measured by connecting the tension measuring component 1 to the detector body 4.

[0041] Furthermore, the clamping unit includes a support plate 32, through which a threaded rod 33 passes. The threaded rod 33 is threadedly connected to the support plate 32, and one end of the threaded rod 33 near the tail cone through hole is rotatably connected to a clamping plate 34. The clamping plate 34 can abut against the detector body 4. By setting the fixing component 3, the effect of clamping and fixing different detector bodies 4 is achieved. The threaded rod 33 in the support plate 32, in conjunction with the clamping plate 34, can be flexibly adjusted according to the size of different detector bodies 4, which greatly enhances the adaptability of the fixing component 3 to detectors of various specifications, reduces the cost for enterprises to equip multiple fixing devices due to different detector specifications, and improves the practicality of the device.

[0042] Specifically, in this embodiment, the length of the clamping plate 34 is greater than the distance between the clamping plate 34 and the fixing plate 31, or the clamping plate 34 slides in contact with the fixing plate 31, thereby restricting the rotation of the clamping plate 34.

[0043] Specifically, an anti-slip pad 35 is connected to the end face of the clamping plate 34 near the tail cone through hole. The anti-slip pad 35 is made of rubber. By setting the anti-slip pad 35, the contact area between the clamping plate 34 and the detector is increased, the clamping friction is improved, and the practicality of the device is enhanced.

[0044] Specifically, in this embodiment, two clamping units are provided.

[0045] Specifically, the fixing plate 31 is threaded with four fixing bolts 37. The fixing plate 31 is a rectangular plate, and the four fixing bolts 37 are distributed at the four corners of the fixing plate 31.

[0046] Furthermore, the tensile force measuring component 1 includes an open outer shell 101. A scale 102 is installed inside the cavity of the outer shell 101. A pointer 103 is rotatably connected to the surface of the scale 102 near the opening of the outer shell 101. A tensile force transmission mechanism 2 is installed on the side of the scale 102 away from the pointer 103 inside the cavity of the outer shell 101. The tensile force transmission mechanism 2 includes a connecting seat 201, which is disposed on the inner surface of the scale 102. A limiting frame 211 is horizontally arranged on the connecting seat 201. The limiting frame 211 is L-shaped, with one end connected to the connecting seat 201 and the other end rotatably connected to the rotating shaft of the pointer 103. The rotating shaft of the pointer 103 is located within the limiting frame. A gear 202 is provided between the 211 and the dial 102. A rack plate 203 is vertically provided between the gear 202 and the limiting frame 211. The gear 202 and the rack plate 203 are meshed together. A horizontal connecting plate 204 is connected to the lower end of the rack plate 203. The vertical rods of the U-shaped rod 205 are respectively connected to both ends of the connecting plate 204. The vertical rods of the U-shaped rod 205 slide out of the outer shell 101. The horizontal rod of the U-shaped rod 205 is outside the outer shell 101. The horizontal rod of the U-shaped rod 205 is connected to a hook 209. The upper ends of the two vertical rods of the U-shaped rod 205 are respectively connected to springs 207. The upper ends of the springs 207 are connected to the operating frame 210. The operating frame 210 is fixedly connected to the outer shell 101.

[0047] The upper limit of the tension measuring component 1 is set by the distance between the connecting plate 204 and the inner wall of the outer casing 101. The pass / fail standard for the tension measuring component's coupling measurement of the detector is defined according to different ground surfaces and coupling conditions. During actual measurement, the operator pulls the tension measuring component 1, causing the connecting component 2 to drive the detector to generate an upward tension. At this time, the spring 207 deforms under the tension, the U-shaped rod 205 drives the connecting plate 204, and the connecting plate 204 drives the rack plate 203 to rotate the gear 202. The rack plate 203 and the gear 202 are always meshed, and the gear 202 drives the pointer 103 to move on the dial, thus displaying the magnitude of the tension. The coupling effect between the detector and the ground surface can be qualitatively judged based on the magnitude of the tension. The greater the tension, the tighter the coupling between the detector and the ground surface; the smaller the tension, the poorer the coupling effect.

[0048] Specifically, the spring constant of the spring 207 is reasonably selected based on the detector specifications and the expected measurement range, and the spring constant of the spring 207 is between 0.1 and 10 N / M. Limiting the spring constant of the spring 207 to this range, based on the detector specifications and the expected measurement range, ensures both the detector's sensitive capture of minute signal changes and the accuracy and reliability of measurement data within the measurement range, effectively improving the detector's measurement performance and application adaptability.

[0049] Specifically, a transparent plate 104 is installed at the opening of the outer casing 101, and a waterproof sealing gasket is provided at the connection between the transparent plate 104 and the outer casing 101. The installation of the transparent plate 104 on the surface of the outer casing 101 and the provision of a waterproof sealing gasket at the connection not only facilitates reading the pointer 103 index but also effectively prevents moisture infiltration, thus improving the practicality of the device. The transparent plate 104 is made of acrylic.

[0050] Specifically, the upper ends of the two vertical rods of the U-shaped rod 205 are threaded to a circular plate 206. The circular plate 206 is connected to a spring 207 via a spring fixing plate. The two ends of the connecting plate 204 are sleeved on the two vertical rods of the U-shaped rod 205. The connecting plate 204 is fixedly connected to the vertical rods via fixing pins. The upper end of the spring 207 is hook-shaped and is hooked to the fixing plate. The fixing plate is fixedly connected to the operating frame 210 via an anti-rotation pin. The operating frame 210 is integrally formed with the outer shell 101.

[0051] Specifically, the crossbar of the U-shaped rod 205 is slidably connected to a connecting ring 208, the connecting ring 208 is fixedly connected to a hook 209, and the surface of the detector body 4 is fixedly connected to a hook plate 41. The hook plate 41 and the hook 209 are engaged, so that the tension measuring component 1 is connected to the detector body 4.

[0052] Example 2:

[0053] Based on Embodiment 1, in this embodiment, the support plate 32 is slidably connected to the slide rod 36, and the slide rod 36 is threadedly connected to the clamping plate 34. By setting the slide rod 36, the clamping plate 34 is guided to start, which avoids the threaded rod 33 from rotating the clamping plate 34, which would prevent the clamping plate 34 from effectively clamping and fixing the detector body 4, thus improving the practicality of the device.

[0054] Two rubber strips 38 are fixedly connected to the lower surface of the fixing plate 31. The two rubber strips 38 are symmetrically distributed on the lower surface of the fixing plate 31, or the two rubber strips 38 are arranged in a curved array on the lower surface of the fixing plate 31. The rubber strips 38 can enhance the friction between the fixing plate 31 and the contact surface and improve the stability of the fixing component 3.

[0055] The outer casing 101 is a two-way open casing, and both openings of the outer casing 101 are provided with transparent plates 104. A waterproof sealing gasket is provided at the connection of the transparent plates 104. This allows for clear observation of the interior of the outer casing 101 through the transparent plates 104, facilitating internal maintenance, while the waterproof sealing gasket effectively prevents water from seeping in, thus improving the practicality of the device.

[0056] The working principle of a detector embedded coupling effect measurement device is as follows: When using the detector embedded coupling effect measurement device, the preparation work is first carried out through the fixing component 3. The detector tail cone 5 is quickly installed on the fixing plate 31 through the tail cone through hole on the fixing plate 31. Then, according to the size of the detector, the threaded rod 33 in the support plate 32 is rotated to adjust the clamping plate 34. The anti-slip pad 35 is used to increase the friction and the sliding rod 36 is used for guidance to firmly clamp the detector. At the same time, the rubber strip 38 under the fixing plate 31 contacts the ground to increase stability. The fixing plate 31 is fixed in the detection position by four fixing bolts 37.

[0057] During measurement, the operator hangs the hook 209 on the hook plate 41 and pulls the tension measuring component 1, causing the operating frame 210 to deform the spring 207. The U-shaped rod 205 slides along the outer casing 101, pulling the detector through the hook 209 on the connecting ring 208 to generate tension. The movement of the U-shaped rod 205 drives the connecting frame and the rack plate 203 to move, and the gear 202 meshing with the rack plate 203 rotates accordingly, thereby driving the pointer 103 fixed on the gear 202 to move on the dial 102, displaying the position. The tensile force value is displayed. Since the tensile force measuring component 1 has an upper limit value set in advance according to different ground surfaces and coupling conditions, and the elastic coefficient of spring 207 is in a reasonable range of 0.1-10 N / M, it can accurately reflect the force condition of the detector. The larger the tensile force value, the tighter the coupling between the detector and the ground surface. The smaller the tensile force value, the worse the coupling effect. By observing the tensile force value displayed by pointer 103 and comparing it with the set qualified standard, the operator can qualitatively judge the coupling effect between the detector and the ground surface and complete the measurement work.
