Description

Technical Field

[0001] This utility model relates to the field of natural gas extraction equipment technology, and in particular to a stethoscope device. Background Technology

[0002] In the field of natural gas extraction, "listening to the equipment" refers to analyzing the equipment's operating status in real time using acoustic or vibration monitoring technologies to prevent malfunctions and improve safety and efficiency. For example, natural gas extraction equipment operates in high-pressure, high-temperature, and corrosive environments for extended periods, making it prone to malfunctions due to wear, loosening, or fatigue. Listening to the equipment can capture abnormal sounds or vibration signals during operation, identify early-stage faults, and allow for repairs before the fault worsens, thus avoiding sudden downtime.

[0003] In related technologies, the stethoscope head is a flat structure, so it can only fit a flat surface. If the area to be auscultated is a curved or irregular surface, the stethoscope head cannot form a good fit, resulting in a large deviation between the auscultation results and the actual situation.

[0018] Two outer portions, each connected to one side of the middle portion in the first direction, each outer portion having a plurality of second sliding grooves on its side facing the middle portion. These second sliding grooves extend vertically and penetrate the upper and lower surfaces of the outer portions, forming the first through hole by the interaction of the second and first sliding grooves.

[0019] Two bolts, one of which connects one of the outer portions to the middle portion, and the other bolt connects the other outer portion to the middle portion, and the axial directions of both bolts are parallel to the first direction.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0043] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0044] Please see Figure 1 This utility model provides a stethoscope device 1, including an earplug 11, a cannula 12, and a stethoscope head 13. One end of the cannula 12 is connected to the earplug 11, and the stethoscope head 13 is connected to the other end of the cannula 12. Please refer to the following: Figure 2 and Figure 3 The hearing head 13 includes a main body 131 and multiple tentacles 132, the main body 131 being arranged in a vertical direction (e.g., Figure 4 As shown in the Y direction, a plurality of first through holes 1311 are provided, with both ends of the plurality of first through holes 1311 penetrating the upper and lower surfaces of the main body 131. A plurality of contact feet 132 are slidably disposed in the plurality of first through holes 1311, and one end of each contact foot 132 protrudes from the lower surface of the main body 131. The plurality of contact feet 132 are configured to move axially along the first through holes 1311 according to the shape of the geometric surface of the location to be auscultated, so that the end of each contact foot 132 protruding from the main body 131 can contact the geometric surface of the location to be auscultated.

[0045] The geometric surface of the location to be auscultated can be a plane, a curved surface, or other irregular surface. The number of antennae must be at least three, ensuring that at least three antennae can make multiple points of contact with the aforementioned surface to avoid accidental deviations. For example, the number of antennae can be eight.

[0046] In this embodiment, when auscultating a location, if the geometric surface of the location is curved or irregular, the auscultator 13 is gradually moved closer to the location until some of the pins 132 abut against the geometric surface of the location. At this point, all the pins 132 remain stationary. The distance between the auscultator 13 and the location is further reduced. During this process, the number of pins 132 in contact with the geometric surface of the location increases. The pins 132 that were previously in contact with the geometric surface move along the axis of the corresponding first through hole 1311 until all the pins 132 are in contact with the geometric surface. At this point, at least some of the pins 132 protrude from the lower surface of the body 131 by a different distance than the other pins 132, thus adapting to different geometric surfaces.

[0047] Therefore, in this embodiment of the application, by setting multiple tentacles 132 that can move relative to the main body 131, when auscultating different geometric surfaces, the multiple tentacles 132 can move independently to ensure that all tentacles 132 are in contact with the geometric surface, thereby forming multi-point contact with the geometric surface and preventing large deviations between the auscultation structure and the actual situation.

[0048] Please refer to the following: Figure 3 and Figure 4In some embodiments, the end of the contact foot 132 located inside the first through hole 1311 is provided with a first step 1231, and the end of the first through hole 1311 located on the lower surface of the main body 131 is provided with a second step 1312 that can abut against the first step 1231.

[0049] The second step 1312 abuts against the first step 1231, preventing the first step 1231 from falling out of the first through hole 1311, thereby preventing the contact 132 from falling out of the first through hole 1311. For example, both the contact 132 and the first step 1231 can be columnar structures, while the second step 1312 can be annular. The diameter of the contact 132 can be approximately 8 mm, the diameter of the first step 1231 can be approximately 9 mm, the inner diameter of the second step 1312 can be approximately 8 mm, and the inner diameter of the first through hole 1311 can be approximately 9 mm, thus enabling the second step 1312 to abut against the first step 1231 and allowing the contact 132 to move along the second step 1312.

[0050] In some embodiments, the earpiece 13 further includes a plurality of first springs (not shown in the figure), which are disposed one-to-one with a plurality of first through holes 1311. The first springs are arranged in a compressed manner, and the first springs abut against one end of the contact foot 132 located in the first through hole 1311 and apply an elastic force to the contact foot 132 to push the end of the contact foot 132 away from the first spring to protrude from the lower surface of the body 131.

[0051] The first spring applies an elastic force to the probe 132 to push the end of the probe 132 away from the spring to protrude from the lower surface of the body 131, so that the length of all probes 132 protruding from the lower surface of the body 131 is approximately the same when they are not in contact with the geometric surface of the location to be auscultated, which can avoid the situation where some probes 132 are stuck in the first through hole 1311 and do not contact the geometric surface.

[0052] Please refer to the following: Figure 2 and Figure 5 In some embodiments, the earpiece 13 further includes a plurality of carriers 135, which are all mounted on the upper surface of the main body 131, and the plurality of carriers 135 cover the plurality of first through holes 1311 in a one-to-one correspondence. The end of the first spring away from the contact foot 132 abuts against the carrier 135, wherein the lateral dimension of the carrier 135 is larger than the diameter of the first through hole 1311.

[0053] The lateral dimension of the support member 135 is larger than the through hole of the first through hole 1311, which can prevent the support member 135 from falling into the first through hole 1311 and causing the first spring to fail. For example, the support member 135 can be a columnar structure, the diameter of the support member 135 can be approximately 10 mm, and the inner diameter of the first through hole 1311 can be approximately 9 mm.

[0054] Please refer to the following: Figure 2 , Figure 3 and Figure 5 In some embodiments, the earpiece 13 further includes a plurality of guide rods 136, which are connected one-to-one with a plurality of carrier members 135, and the guide rods 136 are located within a first through hole 1311, with a first spring sleeved on the guide rod 136. Each of the plurality of contact feet 132 has a receiving cavity 1232 at one end within the first through hole 1311, and the receiving cavity 1232 of the plurality of contact feet 132 corresponds to the end of each guide rod 136 located away from the carrier member 135.

[0055] The first spring is sleeved on the guide rod 136, which can limit the radial deformation of the first spring along the first through hole 1311, so that the first spring can only apply an elastic force along the axial direction of the first through hole 1311 to the contact foot 132.

[0056] The extension direction of the guide rod 136 is approximately coincident with the axial direction of the first through hole 1311. The guide rod 136 is accommodated in the corresponding receiving cavity 1232, so that the guide rod 136 can guide the contact foot 132, that is, restrict the contact foot 132 to move only along the guide rod 136. For example, both the guide rod 136 and the receiving cavity 1232 can be columnar structures, the diameter of the guide rod 136 can be approximately 6 mm, and the inner diameter of the receiving cavity 1232 can be approximately 6 mm.

[0057] Please see Figure 6 In some embodiments, the earpiece 13 also includes a cover 133, which is connected to the upper surface of the main body 131. The conduit 12 is connected to the cover 133. The lower surface of the cover 133 is provided with a plurality of receiving grooves 1331, which correspond to and accommodate a plurality of carriers 135.

[0058] The edge of the support member 135 can contact the side wall of the receiving groove 1331, and the depth of the receiving groove 1331 is approximately the same as the height of the support member 135, so that after the cover 133 is connected to the main body 131, the receiving groove 1331 can restrict the movement of the support member 135.

[0059] Please refer to the following: Figure 1 and Figure 7 In some embodiments, the main body 131 is provided with a cavity 1316, which penetrates the upper surface of the main body 131, and a plurality of first through holes 1311 are respectively located on both sides of the cavity 1316. The cover 133 is provided with a guide 1332, one end of which penetrates the lower surface of the cover 133 and is opposite to the cavity 1316, and the other end of which protrudes from the upper surface of the cover 133 and is connected to the conduit 12.

[0060] In this embodiment, the sound wave propagates in the following order: contact 132, main body 131, cavity 1316, conductive element 1332, conduit 12 and earplug 11, and finally propagates into the ear of the worker.

[0061] The cavity 1316 can be a cuboid structure, with a length of approximately 46 mm and a width of approximately 20 mm. The cavity 1316 can amplify sound waves.

[0062] The conductive element 1332 is opposite to the cavity 1316, which can prevent the sound wave from being blocked on its way from the cavity 1316 to the conductive element 1332, thus preventing sound wave distortion.

[0063] Please refer to the following: Figure 1 , Figure 4 and Figure 8 In some embodiments, the main body 131 includes a central portion 1313, two outer portions 1314, and two bolts (not shown in the figure). The central portion 1313 is in a first direction (e.g., Figure 4 Multiple first grooves 1313a are provided on both opposite sides of the middle portion 1313 (as shown in the X direction). These first grooves 1313a extend vertically and penetrate the upper and lower surfaces of the middle portion 1313, with the first direction perpendicular to the vertical direction. Two outer portions 1314 are respectively connected to both sides of the middle portion 1313 in the first direction. Multiple second grooves 1314a are provided on the sides of the two outer portions 1314 facing the middle portion 1313. These second grooves 1314a extend vertically and penetrate the upper and lower surfaces of the outer portions 1314. The second grooves 1314a and the first grooves 1313a together form a first through hole 1311. One bolt connects one outer portion 1314 to the middle portion 1313, and another bolt connects the other outer portion 1314 to the middle portion 1313. The axial directions of both bolts are parallel to the first direction.

[0064] The first groove 1313a and the second groove 1314a can be roughly regarded as mirror images, that is, the first groove 1313a and the second groove 1314a are each half of the first through hole 1311.

[0065] The two outer portions 1314 are respectively connected to the two sides of the middle portion 1313 in the first direction. That is, all the first through holes 1311 are respectively close to the two sides of the main body 131 in the first direction, so that the probes 132 can be dispersed as much as possible, and prevent the probes 132 from being too concentrated, which would lead to a large probability of randomness in the auscultation results.

[0066] Please continue reading. Figure 1 , Figure 4 and Figure 8In some embodiments, both the first and second sides are provided with screw holes 1313b, and each of the two outer portions 1314 is provided with a second through hole 1314b corresponding to the two screw holes 1313b respectively. The bolt shank passes through the through hole and engages with the screw hole 1313b via a thread. The head 13 also includes two second springs (not shown in the figure), which are respectively compressed and sleeved on the bolt, with one end of the second spring abutting against the outer portion 1314 and the other end abutting against the bolt nut.

[0067] The bolt and screw hole 1313b are threaded together. When the bolt does not rotate relative to the main body 131, the distance between the bolt nut and the main body 131 remains approximately constant. One end of the second spring abuts against the bolt nut, and the other end abuts against the outer portion 1314, thereby applying an elastic force towards the main body 131 to the outer portion 1314. Under the action of the elastic force, the second slide groove 1314a of the outer portion 1314 can clamp the contact foot 132 with the first slide groove 1313a, thus creating friction between the contact foot 132 and the first and second slide grooves 1313a. This friction can overcome the elastic force applied to the contact foot 132 by the first spring, thereby restricting the movement of the contact foot 132. Furthermore, the magnitude of the friction can be adjusted by adjusting the bolt to change the force applied by the second spring to the outer portion 1314.

[0068] For example, after all the probes 132 are in contact with the geometric surface of the location to be auscultated, the bolt can be rotated to reduce the distance between the bolt nut and the body 131. After the distance between the bolt nut and the body 131 is reduced, the second spring is further compressed, which increases the elastic force applied by the second spring to the outer part 1314, thereby increasing the friction between the probes 132 and the first groove 1313a and the second groove 1314a, thereby overcoming the elastic force applied by the first spring to the probes 132 and restricting the movement of the probes 132.

[0069] After the auscultation device 1 finishes auscultation, the bolt can be rotated in the opposite direction to increase the distance between the bolt nut and the main body 131. After the distance between the bolt nut and the main body 131 increases, the second spring is relatively extended, which reduces the elastic force applied by the second spring to the outer part 1314. This reduces the friction between the contact foot 132 and the first slide groove 1313a and the second slide groove 1314a. The friction is insufficient to overcome the elastic force applied by the first spring to the contact foot 132, so that the contact foot 132 is reset under the action of the elastic force applied by the first spring.

[0070] In some embodiments, the auscultatory device 1 further includes a listening component 14 disposed on the catheter 12.

[0071] The listening component 14 can record and store sound waves, facilitating analysis of the sound waves at the end of auscultation. For example, the listening component 14 may include a power supply, a sound wave vibration sensor, and a storage device. The power supply powers the sound wave vibration sensor and the storage device, and the sound wave vibration sensor records and stores the detected sound waves in the storage device.

[0072] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
