Description

Technical Field

[0001] This application relates to detection equipment technology, and more particularly to a bottom-penetrating component and an underwater detection device containing the same. Background Technology

[0002] When conducting rapid on-site water depth measurement, bottom sediment exploration, or target search in shallow water areas (such as rivers, lakes, ports, and aquaculture areas), operators use handheld detection equipment. Handheld detection equipment has advantages such as low cost, intuitive operation, and no need for complex energy sources.

[0003] In related technologies, the detection equipment is equipped with a bottom probe. By sensing the depth of the probe or visually observing the length of the probe submerged in the water, it is possible to intuitively determine whether the bottom has been reached.

[0004] However, current probe rods are generally fixed to the detection equipment with screws, which makes it inconvenient to manually adjust the height of the probe rods and makes it impossible to quickly disassemble and replace them, thus affecting the efficiency of detection operations. Utility Model Content

[0005] This application provides a bottom-detection assembly and an underwater detection device containing the same, in order to solve the technical problems in the related art where the bottom-detection rod of the bottom-detection assembly is inconvenient to adjust in height and inconvenient to disassemble and replace.

[0006] To address the aforementioned technical problems, in one aspect, embodiments of this application provide a bottom-finding component, comprising:

[0007] Bottom probe;

[0008] A support frame has at least two constraint blocks on one side along the height direction, and at least two constraint blocks have coaxially arranged slots, through which the bottom probe rod passes;

[0009] An adjusting member is rotatably mounted on the support frame. The adjusting member is provided corresponding to one of the constraint blocks. The adjusting member has a rotating pin that passes through the support frame and the constraint block. The rotating pin has a deformable part that is recessed in the radial direction.

[0010] The constraint block is provided with a connecting groove to the adjusting member, and the adjusting member has an active position in which the deformable part is directly opposite the connecting groove, and a locking position in which the deformable part is deviated from the connecting groove.

[0011] In the locked position, at least a portion of the rotating pin enters the communicating groove and abuts against the bottom probe to limit the displacement of the bottom probe relative to the constraint block.

[0012] In some possible implementations, the adjusting member includes a pin handle connected to the rotating pin, the pin handle being located on the side of the support frame away from the constraint block, the pin handle being used to drive the rotating pin to rotate synchronously.

[0013] In some possible implementations, the support frame is provided with a protruding limiting post located on the rotation path of the pin handle. The limiting post is configured such that when the bottom probe moves upward relative to the constraint block, it blocks the rotational displacement of the pin handle in the locked position.

[0014] In some possible implementations, the pin handle and the rotary pin key are connected in a cooperative manner.

[0015] In some possible implementations, the deformable portion is a groove provided on the rotating pin, the groove extending along the axial direction of the rotating pin.

[0016] In some possible implementations, the length of the deformed portion is not less than the opening length of the communicating groove.

[0017] In some possible implementations, the side edges of the deformable portion on both sides and the main body of the rotating pin are formed with transitional chamfers or rounded corners.

[0018] In some possible implementations, the probe rod is provided with transverse ribs spaced apart along the height direction.

[0019] In some possible implementations, the probe rod is a hollow carbon fiber tube.

[0020] On the other hand, this application provides an underwater detection device, including a detection body and a bottom-penetrating component as described in any of the above claims disposed on the detection body.

[0021] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0022] 1. The bottom-probing assembly provided in this application utilizes at least two constraint blocks set on the support frame. The coaxial slots on the constraint blocks form a double guide channel to ensure that the bottom-probing rod always maintains axial linear movement and avoids deflection.

[0023] 2. The bottom-probing assembly provided in this application features a radial recessed design on the rotating pin shaft to form a non-complete cylinder. When the deformable part rotates to the connecting groove, it is in an active position, with the recessed area of ​​the deformable part facing the connecting groove, avoiding the internal space of the groove. The bottom-probing rod can slide freely. When the rotating pin shaft rotates to the point where the complete cylindrical section enters the connecting groove, the cylindrical surface of the rotating pin shaft is squeezed into the connecting groove, pressing the bottom-probing rod and using friction to lock the displacement of the bottom-probing rod. The overall structure does not require springs or hydraulic components, and the bottom-probing rod can be manually locked and unlocked by mechanical action without removing bolts. This facilitates the disassembly of the bottom-probing rod and the adjustment of its height on the support frame. The operation is convenient, simple, and easy to learn, which helps to improve the efficiency of the detection operation.

[0024] 3. The bottom-testing component provided in this application includes a pin handle connected to a rotating pin, which allows operators to easily rotate the rotating pin by operating the pin handle, further improving the ease of operation of the adjusting component.

[0025] 4. The bottom-probing assembly provided in this application embodiment has a protruding limiting post on the support frame. The limiting post is located on the rotation path of the pin handle. The limiting post is configured such that when the bottom-probing rod moves upward relative to the constraint block, it blocks the rotational displacement of the pin handle in the locked position. Therefore, when the bottom-probing rod touches the bottom and the rotating pin is subjected to an upward force from the bottom, the pin handle will be blocked by the limiting post to prevent continuous rotation, thereby locking the upward sliding of the bottom-probing rod and ensuring the locking and fastening of the bottom-probing rod.

[0032] This application provides a rotating device for sonar equipment and a gimbal containing the same, thereby solving the technical problem of low efficiency in target searching by sonar equipment in the prior art.

[0033] As described in the background section, the detection device is equipped with a bottom probe. By sensing the depth of the probe or visually observing the length of the probe submerged in the water, one can intuitively determine whether it has reached the bottom.

[0034] However, current probe rods are generally fixed to the detection equipment with screws, which makes it inconvenient to manually adjust the height of the probe rods and makes it impossible to quickly disassemble and replace them, thus affecting the efficiency of detection operations.

[0035] Based on the above description, one or more embodiments of this application provide a bottom-penetrating component and an underwater detection device. The following description, in conjunction with the accompanying drawings, illustrates the solutions of the embodiments of this application.

[0036] like Figures 1 to 5 As shown, the bottom-testing assembly in this application embodiment includes a bottom-testing rod 100, a support frame, and an adjusting component.

[0037] At least two constraint blocks 201 are provided on one side of the support frame along the height direction. At least two constraint blocks 201 are provided with coaxially arranged slots 2011, and the bottom probe rod 100 passes through the slots 2011. An adjusting member is rotatably provided on the support frame. The adjusting member is provided corresponding to one of the constraint blocks 201. The adjusting member has a rotating pin 301 that passes through the support frame. The rotating pin 301 is provided with a deformable part 303 that is recessed in the radial direction.

[0038] The constraint block 201 is provided with a connecting groove 2012 that connects to the adjusting member. The adjusting member has an active position in which the deformable part 303 is directly opposite the connecting groove 2012, and a locked position in which the deformable part 303 is deviated from the connecting groove 2012. In the locked position, at least a portion of the rotating pin 301 enters the connecting groove 2012 and abuts against the bottom probe 100 to limit the displacement of the bottom probe 100 relative to the constraint block 201.

[0039] As can be seen from the above description, the bottom-probing component of this application embodiment utilizes at least two constraint blocks 201 provided on the support frame. The coaxial slots 2011 on the constraint blocks 201 form a double guide channel to ensure that the bottom-probing rod 100 always maintains axial linear movement and avoids deflection.

[0040] Furthermore, the radial recessed design of the deformable part 303 on the rotating pin 301 forms a non-complete cylinder. When the deformable part 303 rotates to the connecting groove 2012, it is in an active position. The recessed area of ​​the deformable part 303 faces the connecting groove 2012, avoiding the internal space of the slot 2011. The probe rod 100 can slide freely. When the rotating pin 301 rotates to the point where the complete cylindrical section enters the connecting groove 2012, the cylindrical surface 304 of the rotating pin 301 is squeezed into the connecting groove 2012, pressing the probe rod 100 and locking the displacement of the probe rod 100 by friction. The overall structure does not require springs or hydraulic components. The probe rod 100 can be manually locked and unlocked by mechanical action without removing the bolts. This facilitates the removal of the probe rod 100 and the adjustment of the height of the probe rod 100 on the support frame. The operation is convenient, simple and easy to learn, which helps to improve the efficiency of the detection operation.

[0041] In some embodiments, the cross-section of the support frame is "door" shaped, including a top plate 202 and side plates 203 on both sides of the top plate 202. A constraint block 201 is disposed on one side plate 203 of the support frame. The top plate 202 of the support frame is used to connect the handheld rod of the underwater detection equipment. A clamping member 205 is provided between the two opposite side plates 203. The clamping member 205 clamps the sensors, probes and other detection components of the underwater detection equipment. It should be noted that the lower end of the bottom probe 100 should be lower than the sensors, probes and other detection components of the underwater detection equipment to protect the detection components from being bumped.

[0042] In some embodiments, the constraint block 201 may be made of high-strength engineering plastic, such as polyoxymethylene (POM) material, and the bottom probe 100 may be made of hollow metal tube or carbon fiber tube, as long as it can be pressed and limited by the rotating pin 301 using friction.

[0043] The adjusting component includes a pin handle 302 connected to the rotating pin 301. The pin handle 302 is located on the side of the support frame away from the constraint block 201. The pin handle 302 is used to drive the rotating pin 301 to rotate synchronously.

[0044] Specifically, such as Figure 4 As shown, the pin handle 302 and the rotating pin 301 are keyed together. One end of the rotating pin 301 is rotatably connected to the constraint block 201, and the other end passes through the constraint block 201 and the side plate 203 of the support frame. The end of the rotating pin 301 that passes through the support frame is the connecting end 306, and the cross-section of the connecting end 306 is approximately "D" shaped. The pin handle 302 is provided with a corresponding "D" shaped groove through which the rotating pin 301 passes. The pin handle 302 and the rotating pin 301 are engaged and plugged together, so that the pin handle 302 drives the rotating pin 301 to rotate.

[0045] Furthermore, a protruding limiting post 204 is provided on the support frame. The limiting post 204 is located on the rotation path of the pin handle 302. The limiting post 204 is configured to block the rotational displacement of the pin handle 302 in the locked position when the bottom probe 100 moves upward relative to the constraint block 201.

[0046] The aforementioned limiting post 204 can be a bolt that is threadedly connected to the side plate 203 of the support frame. When the bottom probe 100 touches the bottom, the bottom probe 100 is subjected to an upward reaction force from the bottom. The force transmitted by the bottom probe 100 to the rotating pin 301 generates a tendency to push the rotating pin 301 to rotate. The limiting post 204 can limit and block the continuous rotation of the pin handle 302, thereby locking the upward sliding of the bottom probe 100.

[0047] It should be noted that the position of the limiting post 204 should be set at the rotation limit position of the pin handle 302. This rotation limit position is generally the cylindrical surface 304 on the other side opposite to the rotating pin 301 and the deformable part 303. Of course, the position of the limiting post 204 can be flexibly adjusted in different design scenarios.

[0048] For example, the pin handle 302 is in Figure 2 When the horizontal position is as shown in the diagram, the deformable part 303 is in the movable position directly opposite the connecting groove 2012, the bottom probe 100 can move freely up and down, and the pin handle 302 is displaced to... Figure 3 When the pin handle 302 is in the vertical position shown in the diagram, it abuts against the limiting post 204. At this time, the deformable part 303 is offset from the connecting groove 2012, and the rotating pin 301 and the cylindrical surface 304 on the other side opposite to the deformable part 303 enter the connecting groove 2012 and press against the bottom probe 100.

[0049] In some embodiments, such as Figure 4 As shown, the deformable part 303 is a groove provided on the rotating pin 301, and the groove extends along the axial direction of the rotating pin.

[0050] The groove has opposing side walls along the axial direction of the rotating pin 301, and the other two sides of the groove completely penetrate the rotating pin 301 to avoid interference with the probe rod 100 in the active position.

[0051] like Figure 5 As shown, the length of the deformable part 303 is not less than the opening length of the connecting groove 2012. The opening length of the connecting groove 2012 refers to the length extending along the axial direction of the rotating pin 301. This design can prevent interference between the other cylindrical surfaces 304 of the rotating pin 301 and the bottom probe 100 when the length of the deformable part 303 is less than the opening length of the connecting groove 2012 in the active position.

[0052] It should be noted that in this embodiment, the connecting groove 2012 is a circular groove and the deformable part 303 is a groove with an approximately rectangular opening. As an alternative implementation, the connecting groove 2012 can also be a circular groove, as long as it does not affect the active position and locking position of the deformable part 303.

[0053] In some embodiments, the side edges of the deformable portion 303 on both sides and the main body of the rotating pin 301 are formed with transitional chamfers 305 or rounded corners. During the rotation of the rotating pin 301, the rounded corners or chamfers 305 first contact the bottom probe 100. This prevents the cylindrical surface 304 of the rotating pin 301 from bumping and scratching the bottom probe 100 when it is pressed.

[0054] Furthermore, the probe rod 100 is provided with horizontal ribs arranged at intervals along the height direction. The horizontal ribs can cooperate with the cylindrical surface 304 of the rotating pin 301 to increase the friction, thereby enhancing the locking strength of the probe rod 100 and the rotating pin 301 in the locked position.

[0055] Another embodiment of this application provides an underwater detection device, including a detection body and a bottom-penetrating component as described in any of the above embodiments, disposed on the detection body.

[0056] Since the underwater detection equipment includes the bottom-penetrating component as described in any of the preceding embodiments, it possesses all the advantages of a bottom-penetrating component. Of course, in addition to the bottom-penetrating component, the underwater detection equipment should also include other related components for performing normal underwater detection operations. These related components can be components of handheld underwater detection equipment in the related art, which will not be elaborated upon in the embodiments of this application.

[0057] It should be understood that although quantifiers such as "first," "second," etc., may be used herein to describe various units, these units should not be limited by these terms. These terms are used merely to distinguish one unit from another. For example, without departing from the scope of the exemplary embodiments, a first unit may be referred to as a second unit, and similarly, a second unit may be referred to as a first unit.

[0058] The directional terms such as "outer," "middle," and "inner" mentioned or potentially used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0059] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0060] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from the method of this application, and these improvements and additions should also be considered within the protection scope of this utility model.
