Description

Technical Field

[0001] This utility model relates to the field of seismic wave detection equipment technology, and in particular to a single-hole seismic wave imaging device. Background Technology

[0002] Single-hole seismic imaging devices are commonly used in geophysical exploration, and are widely applied in engineering geological surveys, mineral resource exploration, and other work. These working environments are typically in the field, such as construction sites, mountainous areas, or near drilling platforms, where environmental conditions are often complex, and operators frequently need to move between different measuring points.

[0003] Existing seismic imaging equipment typically includes core detection instruments (such as the hydrophone in this proposal) as well as ground control and data acquisition units. For field operation, these equipment components must be safely transported to the work site and stably installed and deployed during operation to ensure the accuracy of the detection data.

[0004] Currently, to achieve portability, the main unit of such equipment is often transported in a protective case. However, upon arrival at the work site, operators need to remove the main unit from the case, set up a separate tripod or workbench, and then install the main unit onto the support. This design, which separates the main body of the equipment, the transport case, and the supporting structure, results in numerous components being carried, and the on-site deployment process is cumbersome and time-consuming.

[0005] This inefficient deployment is particularly pronounced when rapid relocation of measuring points is required or when seizing operational time in adverse weather conditions. Furthermore, the separate support structure occupies additional space during storage and transportation, increasing the burden on field operations. How to efficiently combine the portable transport function of the equipment with its rapid and stable on-site deployment capability is a pressing technical problem in this field. Therefore, this invention proposes a single-hole seismic wave imaging device to address the shortcomings of existing technologies. Utility Model Content

The support column and the limiting shaft are used to limit the sliding stroke of the sliding plate and cooperate with the movable plate to trigger its rotation when the sliding plate slides out to the position. Preferably, the bottom inner wall of the base is fixed with a support column and a limiting shaft, which are used to limit the sliding stroke of the sliding plate, and cooperate with the movable plate to make it rotate when the sliding plate slides out to the position.

[0010] By adopting the above technical solution, the device also includes a hydrophone, which is housed within the housing space when the cover is closed.

[0011] Preferably, when the cover rotates to the closed state relative to the base, the receiving space formed by the base and the cover together accommodates the hydrophone. At this time, the hydrophone is confined within the space as the cover closes, and is in a static state of being stored and protected, thus realizing the storage and protection of the hydrophone when the equipment is not in use. By adopting the above technical solution, the device further includes a locking mechanism, which is used to lock the closed cover onto the base.

[0020] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0021] Example: A single-aperture seismic imaging device, 1. Figure 2 and Figure 4 The device includes a base 1 and a cover 4 that is closable and connected to the base 1. The base 1 and the cover 4 together define a receiving space for accommodating a hydrophone 5. The device also includes a retractable mechanism 2, which is integrally disposed at the bottom of the base 1. The retractable mechanism 2 includes a sliding plate 21 and a support leg 22. The sliding plate 21 is slidably connected along the length of the inner wall of the bottom of the base 1, and the upper end of the support leg 22 is rotatably connected to the base 1. Specifically, a single-aperture seismic imaging device has a core component consisting of a base 1 and an openable / closable cover 4. The combined storage space defined by the two components can properly house and protect the hydrophone 5. The base 1 has a retraction mechanism 2 at its bottom, with a sliding plate 21 that slides along the inner wall of the bottom of the base 1. Pulling the sliding plate 21 can drive the upper support leg 22 connected to the base 1 to rotate and unfold through a linkage structure, forming a stable support. When storing, pressing the retraction mechanism 2 allows for folding and storage.

[0022] It also includes a movable plate 28 and a connecting rod 23. The movable plate 28 is rotatably connected to the lower surface of the sliding plate 21 via its central axis. The first end of the connecting rod 23 is rotatably connected to the end of the movable plate 28 away from its central axis, while the second end of the connecting rod 23 is rotatably connected to the side wall of the support leg 22 near its upper end. With this configuration, when the sliding plate 21 is pulled outward from the bottom of the base 1, the linear motion of the sliding plate 21 causes the movable plate 28 to translate and rotate around its central axis. The rotation of the movable plate 28 is transmitted through the connecting rod 23, driving the support leg 22 to unfold outward around its rotational connection point with the base 1, thereby transforming the device from a compact storage form to a stable ground support form. Specifically, the retraction mechanism 2 of the device also includes a movable plate 28 and a connecting rod 23. The movable plate 28 is rotatably connected to the lower surface of the sliding plate 21 via a central shaft, and the two ends of the connecting rod 23 are rotatably connected to the distal end of the movable plate 28 and the upper sidewall of the support leg 22, respectively. When the sliding plate 21 is pulled outward, its linear motion causes the movable plate 28 to translate and rotate. The power is transmitted through the connecting rod 23, driving the support leg 22 to unfold outward, realizing the transformation of the device from a retracted form to a stable support form.

[0023] The retraction mechanism 2 also includes a bearing seat 24, a spring 25, a connecting shaft 27, a support column 26, and a limiting shaft 29. The bearing seat 24 is fixedly connected to the lower surface of the sliding plate 21. One end of the connecting shaft 27 is linked with the movable plate 28, so that the movable plate 28 can drive the connecting shaft 27 to move during rotation. The spring 25 is a tension spring, with its two ends fixedly connected to the bearing seat 24 and the other end of the connecting shaft 27, respectively. When the support leg 22 is in the extended state, the spring 25 is stretched, and the elastic potential energy it generates is converted into a continuous tension on the connecting shaft 27, which reacts through the bearing seat 24 to the sliding plate 21, so that the connecting rod 23 of the entire retraction mechanism 2 remains taut. Specifically, the auxiliary components of the retraction mechanism 2 include a bearing seat 24, a spring 25, a connecting shaft 27, a support column 26, and a limiting shaft 29. The bearing seat 24 is fixed to the lower surface of the sliding plate 21, and one end of the connecting shaft 27 is linked to the movable plate 28. When the support leg 22 unfolds, the movable plate 28 rotates, causing the connecting shaft 27 to shift and stretch the spring 25. The elastic potential energy of the spring 25 is converted into a continuous tensile force, which reacts through the bearing seat 24 onto the sliding plate 21, keeping the connecting rod 23 taut for stable support.

[0024] A support column 26 and a limiting shaft 29 are also fixedly connected to the bottom inner wall of the base 1. The support column 26 and the limiting shaft 29 are used to physically block and precisely limit the outward sliding stroke of the sliding plate 21. At the same time, their positions are set to cooperate with the movable plate 28 to trigger its rotation when the sliding plate 21 slides out to the position, ensuring that the starting timing of the unfolding action is accurate. Specifically, the support column 26 and the limiting shaft 29 fixed to the inner wall of the bottom of the base 1 have the core function of physically blocking and precisely limiting the outward sliding stroke of the sliding plate 21, preventing the sliding plate 21 from sliding out excessively. The positions of the two are precisely set, and when the sliding plate 21 slides out to the correct position, it will precisely cooperate with the movable plate 28 to trigger its rotation, ensuring that the starting timing of the unfolding action of the support leg 22 is accurate and ensuring the smooth linkage of the entire retraction mechanism 2.

[0025] Reference Figures 1 to 3 It also includes a hydrophone 5, which is housed within a receiving space defined by the base 1 and the cover 4 when the cover 4 is closed, and is also equipped with a locking mechanism 3; please refer to Figure 1 and Figure 3 The locking mechanism 3 includes a base plate 35 fixedly connected to the cover 4; a connecting rod 32 rotatably connected to the base plate 35; a buckle plate 36 fixedly connected to the free end of the connecting rod 32; a locking hole 34 fixedly connected to the base 1, the locking hole 34 having a through hole for the buckle plate 36 to pass through; and a buckle 31 fixedly connected to the base 1, the buckle 31 having a slot for the connecting rod 32 to engage. Specifically, the device includes a hydrophone 5. When the cover 4 is closed, the hydrophone 5 is securely housed within the space defined by the base 1 and the cover 4. A locking mechanism 3 assists in fixation; its base plate 35 is fixedly connected to the cover 4, a connecting rod 32 is rotatably connected to the base plate 35, and a buckle 36 is mounted on the free end of the connecting rod 32. A buckle 31 on the base 1 allows the connecting rod 32 to engage, and the through hole of the locking hole 34 allows the buckle 36 to pass through, achieving a secure lock to protect the hydrophone 5.

[0026] The locking mechanism 3 also includes a limiting component 33 disposed in the base 1 and cooperating with the lock hole component 34; the limiting component 33 includes a connecting plate 331 movably disposed inside the lock hole component 34 and a second spring 332; the two ends of the second spring 332 abut against the inner wall between the connecting plate 331 and the base 1, and the lock hole component 34 is also integrally formed with a padlock hole through which an external lock can pass. Specifically, the limiting component 33 of the locking mechanism 3 is installed inside the base 1 and cooperates with the lock hole component 34. In the component, the connecting plate 331 is movably disposed inside the lock hole component 34, and the two ends of the spring 332 abut against the connecting plate 331 and the inner wall of the base 1, and can lock the buckle plate 36 through elastic rebound. The padlock hole integrally formed by the lock hole component 34 can be inserted into an external lock, further improving the locking security when the device is stored and protecting the internal hydrophone 5.

[0027] Working principle: During deployment, the operator pulls the sliding plate 21 outward, and the sliding plate 21 slides out along the length of the inner wall of the bottom of the base 1 until it is limited by the support column 26 and the limiting shaft 29. During the sliding process, the sliding plate 21 drives the movable plate 28 to move together through its central axis and causes it to rotate. The rotation of the movable plate 28 is transmitted to the support leg 22 through the connecting rod 23, driving the support leg 22 to rotate outward around its rotation connection point until a stable support state is formed. At the same time as the movable plate 28 rotates, it drives the connecting shaft 27 to move, so that the spring 25 fixed between the bearing seat 24 and the connecting shaft 27 is stretched. The tension of the spring 25 acts in the opposite direction on the entire linkage mechanism to ensure that the support leg 22 is deployed in place and remains tight and stable.

[0028] When storing, press the retractable mechanism 2 to fold and store it into the bottom of the base 1, place the hydrophone 5 into the storage space, and close the cover 4 on the base 1; then, flip the connecting rod 32 fixed to the bottom plate 35 on the cover 4 so that it engages with the slot of the buckle 31 fixed on the base 1; then press the buckle plate 36 at the end of the connecting rod 32 so that the buckle plate 36 passes through the locking hole 34 fixed to the base 1; during the passage, the buckle plate 36 squeezes the connecting plate 331 in the limiting assembly 33, forcing the connecting plate 331 to compress the second spring 332. When the buckle plate 36 has completely passed through the locking hole 34, the compressed second spring 332 releases its elastic potential energy, pushes the connecting plate 331 back and locks it behind the buckle plate 36, achieving a firm lock; if needed, an external lock can also be added to the padlock hole of the locking hole 34. The use of the locking mechanism 3 can keep the equipment in a protected state when it is not in use.
