Depth sounding valve and ship

Abstract

The application provides a sounding valve, and relates to the technical field of ships. According to the sounding valve provided in the application, when sounding operation is needed, a crew member can drive a force applying member to rotate around an axis, drive a valve core to rotate, switch the valve core from a state of disconnecting spaces on both sides of the valve core to a state of connecting the spaces on both sides of the valve core, and along with the process, a counterweight member moves along the force applying member to at least a middle part of the force applying member in a predetermined direction. Thus, the counterweight member is switched from the original position on the first side of the force applying member to a new position along with the opening of the sounding valve, and in the new position, the counterweight member no longer promotes the valve core to reset to the state of disconnecting the spaces on both sides of the valve core or promotes the valve core to reset to the state of disconnecting the spaces on both sides of the valve core in a weaker way.

Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a depth sounding valve and a ship. Background Technology

[0002] Ships currently use sounders to measure tank levels, and these sounders typically use manually operated self-closing valves at the end. During measurement, crew members must overcome the weight of the valve's weight to open the valve's passage before the measurement can be performed. This measurement work is not easy or convenient for crew members.

[0003] In existing technologies, foot-operated self-closing depth sounders have emerged. These typically use fixed pulleys and ropes to activate the foot pedal. However, the installation of fixed pulleys and ropes requires additional installation space, resulting in a relatively high actual height for the self-closing depth sounder. This places high demands on the installation space required for its application on ships, especially on container ships. In some cases, the depth sounder's measuring end is located inside the lashing bridge, where the installation space is extremely limited, making it impossible to install and use a conventional foot-operated self-closing depth sounder. In such situations, only a more traditional depth valve structure can be used. During crew measurements, manual operation by two people is required: one person opens the depth valve structure while the other performs the measurement.

[0004] To address the space requirements for installation, existing technologies have specifically incorporated automated equipment into self-closing depth sounding devices. For example, motors, winches, and ropes are used to automatically pull the foot pedal of the self-closing depth sounding device. In this approach, only manual operation of opening and closing the winch is required to activate and deactivate the self-closing depth sounding device, thus balancing the installation space requirements and the convenience of single-person operation to a certain extent.

[0005] However, the above-mentioned scheme requires the use of external cables for the winch and motor, as well as wiring work on the deck. The cables can also pose safety hazards. In addition, the exposed winch and ropes are too close to the crew during depth sounding, making it difficult to set up protective measures. The rotating winch may threaten the personal safety of the crew. Summary of the Invention

[0006] In view of this, this application provides a depth sounding valve and a ship, with the aim of solving the above-mentioned technical problems to a certain extent.

[0007] This application provides a depth sounding valve, which is installed on the deck of the ship, and the depth sounding valve includes:

[0008] A valve body having a valve cavity extending along the direction of gravity;

[0009] A valve core located within the valve cavity, the valve core being configured to rotate about an axis perpendicular to the direction of gravity to connect and disconnect spaces in the valve cavity located on either side of the valve core in the direction of gravity.

[0010] A drive assembly includes a force-applying member disposed on the outside of the valve body, the force-applying member extending along a predetermined direction intersecting the extension direction of the axis, the valve core being connected to the middle portion of the force-applying member in the predetermined direction, and the force-applying member being configured to rotate along the axis to drive the valve core to move within the valve cavity.

[0011] The drive assembly further includes a counterweight component, which is movably connected to the force-applying component so as to be able to move along the predetermined direction;

[0012] Wherein, when the counterweight is configured to be located on the first side of the force-applying member in the predetermined direction, it disconnects the spaces of the valve cavity located on both sides of the valve core in the direction of gravity. The counterweight and the force-applying member are further configured such that when the force-applying member drives the valve core to rotate to connect the spaces of the valve cavity located on both sides of the valve core in the direction of gravity, the counterweight moves from the first side to at least the middle of the force-applying member in the predetermined direction.

[0013] Preferably, when the counterweight member and the force-applying member are configured such that the force-applying member drives the valve core to rotate to connect the valve cavity to the spaces located on both sides of the valve core in the direction of gravity, the counterweight member moves from the first side to the middle of the force-applying member in the predetermined direction;

[0014] The counterweight moves to the center of the predetermined direction of the force-applying component and abuts against the valve body.

[0015] Preferably, when the counterweight member and the force-applying member are configured such that the force-applying member drives the valve core to rotate to connect the valve cavity to the spaces located on both sides of the valve core in the direction of gravity, the counterweight member moves from the first side to the second side of the force-applying member in the predetermined direction;

[0016] The force-applying component includes a force-applying body extending along the predetermined direction, and the force-applying component also includes a connecting body spaced apart from the force-applying body in the extension direction of the axis, the connecting body connecting the force-applying body and the valve core.

[0017] Preferably, the force-applying component further includes a first link and a second link;

[0018] The connecting body extends along the predetermined direction, and the two ends of the connecting body in the predetermined direction are respectively connected to the two ends of the force-applying body in the predetermined direction via the first connecting rod and the second connecting rod.

[0019] Preferably, the counterweight component includes a plurality of counterweight parts, all of which are sleeved on the force-applying body. The plurality of counterweight parts and the first connecting rod are further configured such that the plurality of counterweight parts can move to be sleeved on the outside of the first connecting rod, and the plurality of counterweight parts and the second connecting rod are further configured such that the plurality of counterweight parts can move to be sleeved on the outside of the second connecting rod.

[0020] Preferably, the counterweight component includes a through hole penetrating the counterweight component, and the force-applying body passes through the through hole;

[0021] In this embodiment, at least one of the inner portion of the through hole and the outer portion of the force-applying body is configured as an undulating surface.

[0022] Preferably, the counterweight component includes a through hole penetrating the counterweight component, and the force-applying body passes through the through hole;

[0023] The depth measuring valve further includes an elastic part, which is disposed on one of the inner side of the through hole and the outer side of the force-applying body.

[0024] This application provides a depth sounding valve, which is installed on the deck of the ship, and the depth sounding valve includes:

[0025] A valve body having a valve cavity extending along the direction of gravity;

[0026] A valve core located within the valve cavity, the valve core being configured to rotate about an axis perpendicular to the direction of gravity to connect and disconnect spaces in the valve cavity located on either side of the valve core in the direction of gravity.

[0027] A drive assembly includes a force-applying member disposed on the outside of the valve body, the force-applying member extending along a predetermined direction intersecting the extension direction of the axis, the valve core being connected to the middle portion of the force-applying member in the predetermined direction, and the force-applying member being configured to rotate along the axis to drive the valve core to move within the valve cavity.

[0028] A counterweight component, which is fixedly connected to one side of the force-applying component in the predetermined direction;

[0029] The depth sounding valve further includes a stop member and an elastic member. The valve body includes a receiving portion, the elastic member is disposed within the receiving portion, and the stop member is disposed outside the elastic member. The stop member includes a first guide surface and a second guide surface that are opposite to each other.

[0030] The force-applying member is configured to abut against the first guide surface when it rotates around the axis under external force, so as to push the stop member into the receiving portion, and to abut against the second guide surface, so as to push the stop member into the receiving portion;

[0031] The counterweight, the connecting member, and the stop member are configured such that after the force-applying member passes the stop member, the space on both sides of the valve core in the direction of gravity is connected to the valve cavity of the valve core. They are also configured such that after the external force is released, the second guide surface abuts against the force-applying member to prevent the force-applying member from rotating.

[0032] This application provides a vessel that includes a depth sounding valve as described above.

[0033] Preferably, the vessel includes a deck and a depth sounder penetrating the deck, a portion of the valve body is inserted into the depth sounder, and the valve body includes a positioning surface that abuts against the upper side of the depth sounder;

[0034] The distance H between the positioning surface and the deck satisfies 450mm≤H≤700mm.

[0035] According to the depth sounding valve provided in this application, when a depth sounding operation is required, the crew can drive the force-applying component to rotate around its axis, causing the valve core to rotate. This switches the valve core from a state where the spaces on both sides of the valve core are disconnected to a state where the spaces on both sides of the valve core are connected. As this process proceeds, the counterweight component moves along the force-applying component, at least to the middle of the force-applying component in a predetermined direction. Thus, the counterweight component moves from its original position on the first side of the force-applying component to a new position as the depth sounding valve opens. In this new position, the counterweight component no longer has the function of causing the valve core to return to a state where the spaces on both sides of the valve core are disconnected, or it has a weaker function of causing the valve core to return to a state where the spaces on both sides of the valve core are disconnected.

[0036] Therefore, the crew does not need to continuously apply external force to the force-applying component to counteract the reset effect provided by the counterweight component, nor does the crew need to continuously apply a large force to the force-applying component to counteract the reset effect provided by the counterweight component. Thus, after opening the depth sounding valve, the crew does not need to apply external force to the valve or applies even less external force to maintain the depth sounding process. This allows the crew to complete the depth sounding process independently and reduces their workload during the process.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0046] According to a first aspect of the embodiments of this application, a depth sounding valve is provided. The structure and working principle of the depth sounding valve will be described in detail below with reference to the accompanying drawings.

[0047] According to an embodiment of this application, a depth sounding valve is provided. The depth sounding valve is installed on the deck 40 of a ship. The depth sounding valve includes a valve body, a valve core, and a drive assembly. In an embodiment, the valve body has a valve cavity extending along the direction of gravity. The valve core is located within the valve cavity and is configured to rotate about an axis perpendicular to the direction of gravity to connect and disconnect the spaces of the valve cavity located on both sides of the valve core in the direction of gravity.

[0048] In an embodiment, the drive assembly includes a force-applying member 20 disposed on the outside of the valve body. The force-applying member 20 extends along a predetermined direction intersecting the extension direction of the axis. The valve core is connected to the middle portion of the force-applying member 20 in the predetermined direction. The force-applying member 20 is configured to rotate along the axis to drive the valve core to move within the valve cavity.

[0049] In one embodiment, the drive assembly further includes a counterweight 30, which is movably connected to the force-applying member 20 to be movable along a predetermined direction. When the counterweight 30 is configured to be located on a first side of the force-applying member 20 in the predetermined direction, it disconnects the spaces on either side of the valve core in the direction of gravity within the valve chamber. The counterweight 30 and the force-applying member 20 are further configured such that when the force-applying member 20 rotates the valve core to connect the spaces on either side of the valve core in the direction of gravity within the valve chamber, the counterweight 30 moves from the first side at least to the center of the force-applying member 20 in the predetermined direction.

[0050] Thus, according to the depth sounding valve provided in this application embodiment, when a depth sounding operation is required, the crew can drive the force-applying member 20 to rotate around its axis, causing the valve core to rotate. This switches the valve core from a state where the spaces on both sides of the valve core are disconnected to a state where the spaces on both sides of the valve core are connected. As this process proceeds, the counterweight member 30 will move along the force-applying member 20, at least to the middle of the force-applying member 20 in a predetermined direction. Therefore, the counterweight member 30 moves from its original position on the first side of the force-applying member 20 to a new position as the depth sounding valve opens. At this new position, the counterweight member 30 no longer has the function of causing the valve core to return to a position where the spaces on both sides of the valve core are disconnected, or it has a weaker function of causing the valve core to return to a position where the spaces on both sides of the valve core are disconnected.

[0051] Therefore, the crew does not need to continuously apply external force to the force-applying component 20 to counteract the reset effect provided by the counterweight component 30, nor does the crew need to continuously apply a large force to the force-applying component 20 to counteract the reset effect provided by the counterweight component 30. Thus, after opening the depth sounding valve, the crew does not need to apply external force to the depth sounding valve or applies even less external force to maintain the depth sounding process. This allows the crew to complete the depth sounding process independently and reduces their workload during the depth sounding process.

[0052] Compared to existing technologies, the depth sounding valve provided according to the embodiments of this application does not pose safety hazards due to the introduction of electrically driven structures such as winches and motors. It also effectively reduces the workload of crew members while allowing them to perform depth sounding operations alone. Prior to this application, although various solutions for single-person depth sounding operations had been proposed in the prior art, they still had many limitations in practical applications. Therefore, in most practical applications, a two-person depth sounding operation was still used, with one person keeping the depth sounding valve open and the other person specifically performing the depth sounding operation.

[0053] Maintaining the sounding valve in an open state is not difficult for a single crew member to complete, and maintaining the sounding process for 5-10 minutes for a single operation does not seem difficult either. In other words, when the sounding process is divided between two people, each person's work is "specialized." This reduction in the difficulty of the work has limited the development of improvement ideas for maintaining the sounding valve without maintaining it or with less effort in the existing technology, resulting in a lack of emphasis on improving the overall structure of the sounding valve in this field.

[0054] On the other hand, the depth sounding valve devices used in the existing technology often adopt standard valve structures for components such as valve core, valve body and pedal. These are usually obtained through mass production and bulk purchasing. In this case, improving the depth sounding valve device itself may lead to a decrease in production efficiency and an increase in cost. Therefore, the simplest and most effective way seems to be to add additional electrical components such as winches and motors to the existing standard valve structure. However, this improvement method is more limited in application, and the resulting safety hazards of electrical insulation, tripping, and entanglement are difficult to ignore.

[0055] In this embodiment, the working principle between the valve body and the valve core is a conventional principle, which is only briefly illustrated here as an example. Specifically, the valve structure formed by the valve body and the valve core can be a structure similar to a ball valve. The valve core can be, for example, a spherical structure with a through hole penetrating the spherical structure. When the axis of this through hole intersects the axis of the valve cavity, the through hole can separate the spaces on both sides of the valve core in a non-continuous valve cavity manner, at which point the valve structure is in a non-conductive state. When the through hole rotates around... Figure 1When the axis extending perpendicular to the paper rotates, the through hole rotates accordingly. The openings at both ends of the through hole connect with the spaces on both sides of the valve core, thus connecting the spaces on both sides of the valve core. At this time, the valve structure is in a conductive state, which allows the crew to use tools such as rulers to pass through the valve cavity and the depth sounding tube 50 on the deck 40 in sequence to measure the liquid level depth in the compartment below the deck 40.

[0056] In the embodiments, the valve structure formed by the valve core and the valve body usually has a self-limiting function in the prior art. That is, when the valve core rotates relative to the valve body to open the valve structure, the further rotation of the valve core in the valve body is prevented. In other words, after the valve structure is in position and opened, it limits the position of the valve core itself. This will not be elaborated here.

[0057] In an embodiment, the counterweight member 30 may be, for example, a block-shaped counterweight element, which may be formed of a metal such as steel, and may be fitted onto the outside of the force-applying member 20 to form a sliding connection with the force-applying member 20, as will be described in detail below.

[0058] It should also be noted that, in the embodiments, the “middle part” of the force-applying member 20 to which the counterweight member 30 moves in the predetermined direction should be understood to include the part located between the first side and the second side of the force-applying member 20 in the predetermined direction, and is not limited to the exact center of the force-applying member 20.

[0059] Furthermore, it should be noted that after the counterweight component 30 moves to the middle of the force-applying component 20, it can stop moving and remain in the middle position of the force-applying component 20 without external force. Since it no longer acts as a force-providing object in the lever structure formed after the force-applying component 20 is connected to the valve core, the crew can stop stepping on the force-applying component 20 after using a driving method such as foot pedal, and thus focus on the depth measurement process.

[0060] However, it should be further explained that after the counterweight 30 moves to the middle of the force-applying member 20, it may still have a tendency to move towards the first side of the force-applying member 20. This may require the force-applying member 20 to maintain its current tilt state, thus requiring the crew to continue applying external forces such as foot pressure to the force-applying member 20. However, because the counterweight 30 is closer to the connection point between the force-applying member 20 and the valve core, i.e., the fulcrum of the lever structure, compared to its initial state on one side of the force-applying member 20, as the object providing resistance to the lever structure, the resistance arm of the lever structure is greatly shortened, and the resistance torque is reduced. Even if the crew needs to provide external force to maintain the current open state of the valve core, it is not necessary to provide excessive holding force, which still provides the crew with more focus during depth sounding and reduces the crew's workload.

[0061] Furthermore, according to the depth sounding valve provided in the embodiments of this application, compared with the prior art, the structural adjustments of the finished valve are all on the external components of the valve structure formed by the valve core and the valve body, and the adjustment amount is relatively small.

[0062] According to the depth sounding valve provided in the embodiments of this application, the counterweight member 30 and the force-applying member 20 can be configured such that when the force-applying member 20 drives the valve core to rotate to connect the spaces located on both sides of the valve core in the direction of gravity of the valve cavity, the counterweight member 30 moves from the first side to the middle of the force-applying member 20 in a predetermined direction, and abuts against the valve body when the counterweight member 30 moves to the middle of the force-applying member 20 in the predetermined direction.

[0063] Thus, according to the depth sounding valve provided in this application embodiment, the counterweight 30 is directly connected to the valve body before reaching the connection position between the force-applying member 20 and the valve core, thereby using the valve body to form a stop on the counterweight 30 and limit the valve body. Based on this, by adjusting the lengths of the force-applying member 20 and the counterweight 30, the counterweight 30, after abutting against the valve body, no longer has a tendency to move towards the first side of the force-applying member 20. In this case, the valve structure is in the open state, and the crew no longer needs to apply external force to the force-applying member 20. For example, when the crew steps on the force-applying member 20 to open the valve structure, after the counterweight 30 abuts against the valve body, they no longer need to step on the force-applying member 20.

[0064] In this example, the force-applying member 20 can be formed as a rod-like structure, such as... Figure 1 As shown, the middle part of the force-applying member 20 is connected to the valve core. The second side, i.e., the second end, of the force-applying member 20 can be in a horizontal position when the valve structure is closed, so as to facilitate the crew's stepping. The first side, i.e., the first end, of the rod-shaped structure can have a larger limiting part, which can abut against the counterweight member 30 to prevent the counterweight member 30 from coming off the force-applying member 20. As an example, the limiting part can be, for example, a nut, i.e., the first side of the rod-shaped structure can be formed with external threads that mate with the nut. When the nut is not installed, the counterweight member 30 with a hole can be inserted into the first side of the rod-shaped structure, and then the nut can be screwed onto the first side of the rod-shaped structure.

[0065] According to the depth sounding valve provided in the embodiments of this application, the counterweight 30 and the force-applying component 20 can be configured such that when the force-applying component 20 drives the valve core to rotate and communicate with the valve cavity in spaces located on both sides of the valve core in the direction of gravity, the counterweight 30 moves from the first side to the second side of the force-applying component 20 in a predetermined direction. In the embodiments, the force-applying component 20 includes a force-applying body extending along the predetermined direction, and the force-applying component 20 also includes a connecting body spaced apart from the force-applying body in the extension direction of the axis, the connecting body connecting the force-applying body and the valve core.

[0066] In this embodiment, the counterweight 30 is movably connected to the force-applying body, which is connected to the valve core via a connecting body spaced apart from it. This arrangement allows the counterweight 30 to fully utilize the force-applying body for movement without considering the obstruction of the connection position between the force-applying member 20 and the valve core. Therefore, in this example, the counterweight 30 can substantially move along the force-applying body from the first side of the force-applying member 20 to the second side of the force-applying member 20.

[0067] Therefore, in the above example, the counterweight 30 not only no longer provides resistance to prevent the valve structure from opening, but also provides power for opening the valve structure because it has moved from the first side of the force-applying member 20 to the second side, passing through the connection position between the force-applying member 20 and the valve core. That is, the crew can open the valve structure by stepping on the second side of the force-applying member 20, which simultaneously causes the counterweight 30 to move towards the second side of the force-applying member 20. After the counterweight 30 passes the connection position between the force-applying member 20 and the valve core, the crew can release their foot from stepping on the second side of the force-applying member 20, allowing the counterweight 30 to move to the second side of the force-applying member 20 under its own weight.

[0068] Conversely, after the depth measurement operation is completed, simply stepping on the first side of the force-applying member 20, which is in a raised state, will cause the counterweight member 30 to return to the first side of the force-applying member 20 in a movement process similar to the above-described movement process, so as to re-close the valve structure.

[0069] In this embodiment, the force-applying body can be the rod structure mentioned in the previous example. Similarly, the connecting body can also be a rod structure of the same shape. The connecting body can be connected to the valve core by mechanical connection methods such as welding.

[0070] According to the depth sounding valve provided in the embodiments of this application, the force-applying component 20 may further include a first link and a second link. As described above, the connecting body may extend along a predetermined direction, and the two ends of the connecting body in the predetermined direction may be connected to the two ends of the force-applying body in the predetermined direction via the first link and the second link, respectively.

[0071] Therefore, in the depth-sounding valve provided according to the embodiments of this application, both the first connecting rod and the second connecting rod are located at the ends of the two main bodies, thus not affecting the utilization of the force-applying body, and there is no need to consider the influence of the connection between the connecting body and the force-applying body on the movement of the counterweight component 30. In the embodiments, the counterweight component 30 can still cooperate with the force-applying body by means of opening and being sleeved on the outside of the force-applying body.

[0072] In this embodiment, the two connecting rods and the two main bodies essentially form a frame structure. The long side of this frame extends along a predetermined direction, and the wide side extends along a direction parallel to the axis around which the valve core is wound. In this embodiment, when the force-applying member 20 is stepped on, the first connecting rod and the second connecting rod can be stepped on. That is, the first connecting rod and the second connecting rod not only serve to connect the two main bodies but also provide a larger stepping area.

[0073] According to the depth sounding valve provided in the embodiments of this application, the counterweight component 30 includes a plurality of counterweight parts, which can all be sleeved on the force-applying body. The plurality of counterweight parts and the first connecting rod can also be configured such that the plurality of counterweight parts can move to the outside of the first connecting rod. The plurality of counterweight parts and the second connecting rod can also be configured such that the plurality of counterweight parts can move to the outside of the second connecting rod.

[0074] In this example, each of the multiple counterweights, relative to the overall thicker counterweight member 30, can be a sheet-like structure. This results in a shorter through-hole in each counterweight, allowing the counterweight to slide onto the connecting rod at the corner where it connects to the main body. In this example, after the depth measurement operation is completed, the multiple counterweights can be manually moved onto the first connecting rod. In this case, even if the second side of the force-applying member 20 is accidentally stored, movement of the counterweight member 30 relative to the force-applying member 20 can be prevented. Alternatively, the multiple counterweights can be moved onto the second connecting rod to keep the valve structure in the normally open state.

[0075] According to the depth sounding valve provided in the embodiments of this application, as mentioned in the above description, the counterweight component 30 includes a through hole penetrating the counterweight component 30, and the force-applying body is disposed in the through hole. At least one of the inner side of the through hole and the outer side of the force-applying body is configured as an undulating surface.

[0076] In this embodiment, the undulating surface refers to a surface formed by a continuous alternation of convex and concave structures. Specifically, a frosted surface or a patterned surface can serve as such an undulating surface. This undulating surface actually increases the friction between the inner part of the through hole and the outer part of the force-applying body, thereby slowing down the movement speed of the counterweight 30 along the force-applying body. This "deceleration" setting on the counterweight 30 allows the crew sufficient reaction time to release their foot after the counterweight 30 passes the connection position. On the other hand, although the kinetic energy of the counterweight 30 is limited due to the limited distance it moves, the "deceleration" setting still reduces its kinetic energy, reducing the potential impact on the crew's feet (if the crew does not release their foot). Even without the "deceleration," the impact itself will not cause substantial damage to the crew's feet.

[0077] As an example, the inner side of the through hole and the outer side of the force-applying body can both be provided with undulating surfaces, or the undulating surface can be made only on the outer side of the force-applying body, which is easy to process.

[0078] According to the depth sounding valve provided in the embodiments of this application, in some other examples, the depth sounding valve further includes an elastic portion, which may be disposed on one of the inner side of the through hole and the outer side of the force-applying body. As an example, the elastic portion located between the inner side of the through hole and the outer side of the force-applying body can also provide greater friction, thereby achieving the purpose of "slowing down". As an example, the elastic portion may be formed of rubber, for example, it may be pasted on the inner side of the through hole (e.g., a rubber sheet) and / or the outer side of the force-applying body (e.g., a rubber strip extending along a predetermined direction).

[0079] The first aspect of this application also provides another example of a depth sounding valve. Unlike the above example, the counterweight member 30 is fixedly connected to the first side of the force-applying member 20 in a predetermined direction. In order to ensure that the force-applying member 20 is limited after opening the valve structure, this example is provided with a stop member for stopping the force-applying member 20 and an elastic member that provides a stopping force to the stop member.

[0080] In an embodiment, the valve body may include a receiving portion, an elastic member disposed within the receiving portion (the elastic member may be, for example, a spring), and a stop member disposed outside the elastic member, the stop member including a first guide surface and a second guide surface opposite to each other.

[0081] In an embodiment, the force-applying member 20 is configured to abut against a first guide surface when subjected to external force rotating about an axis to push the stop member into the receiving portion, and to abut against a second guide surface to push the stop member into the receiving portion. As an example, both guide surfaces can be inclined structures, which makes the end of the stop member away from the elastic member wedge-shaped.

[0082] In the embodiment, the counterweight member 30, the connecting member, and the stop member are configured such that after the force-applying member 20 passes the stop member, the space located on both sides of the valve core in the direction of gravity of the valve core connecting the valve cavity (i.e., the valve structure is opened), and are also configured such that after the external force is released, the second guide surface abuts against the force-applying member 20 to prevent the force-applying member 20 from rotating.

[0083] In other words, the force-applying member 20 can abut against the first guide surface under the action of an external force, pressing the stop member into the receiving portion, thereby passing through the stop member. Subsequently, the stop member is ejected under the action of the elastic member. At this point, no external force such as the footing force of the crew member is applied to the force-applying member 20. The force-applying member 20 will have a tendency to reset under the resistance torque of the counterweight member 30 and abut against the second guide surface of the stop member. In this case, the second guide surface is configured to withstand the resistance torque without causing the stop member to retract, thereby limiting the force-applying member 20. When the force-applying member 20 needs to reset, the crew member only needs to lift the second side of the force-applying member 20 with their foot, pushing the second guide surface, so that the force-applying member 20 presses the stop member into the receiving portion, and then passes through the stop member.

[0084] In an embodiment, the groove may be a substantially stepped hole structure, the elastic member may be, for example, a helical spring, which may have a larger outer diameter and is disposed within the larger inner diameter hole of the stepped hole structure, and the stop may be a columnar structure with a wedge-shaped end as described above, and the stop may be disposed within a smaller inner diameter hole further out of the stepped hole structure. In an embodiment, the helical spring may be in a continuously compressed state, in which the stop member extends beyond the receiving portion, and the end of the stop member abutted by the helical spring may have a shoulder for preventing the stop member from dislodging from the receiving portion.

[0085] In actual assembly, the receiving part can be a through-hole structure that penetrates the valve body. The stop member and spring can be installed into the receiving part from the inside of the valve body, and the inner opening of the receiving part can be closed by a structure such as a plug to provide a contact position for the spring.

[0086] According to a second aspect of the embodiments of this application, a ship is provided, which includes the depth sounding valve as described above, and also includes the beneficial effects described above, which will not be repeated here.

[0087] According to the embodiments of this application, the ship includes a deck 40 and a sounding tube 50 penetrating the deck 40. A portion of the valve body is inserted into the sounding tube 50. The valve body includes a positioning surface 11, which abuts against the upper side of the sounding tube 50. In the embodiments, the distance H between the positioning surface 11 and the deck 40 satisfies 450mm ≤ H ≤ 700mm. As an example, the lower part of the valve body has a stepped structure. The smaller outer diameter portion is inserted into the sounding tube 50 for assembly, and the larger outer diameter portion and the smaller outer diameter portion form an annular positioning surface 11, which acts as a shoulder and abuts against the upper end of the sounding tube 50. This height H is set to avoid excessive height, which would occupy too much installation space, and to avoid the positioning surface 11 being too close to the deck 40, which would interfere with personnel movement. Here, as an example, H can be, for example, 500mm, 550mm, 600mm, or 650mm.

[0088] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
