Description

Technical Field

[0001] This application relates to the field of transfer equipment, and in particular to a water sampler transfer device. Background Technology

[0002] In marine scientific research, environmental monitoring, and water resource exploration, collecting samples from water at different depths is a crucial means of obtaining key data. Water samplers, as core tools in these tasks, must be designed to balance efficiency, safety, and accuracy. However, safely and conveniently transferring salvaged water samplers from the work platform to the sampling chamber while maintaining a clean environment, requiring a simple transport trolley with external drive that can be easily detached from the sampler's moving trolley for quick closure of the chamber door, has always been a challenge in this field.

[0003] Currently, to facilitate the transfer of water samplers, many sampling stations or work platforms use transfer trolleys to load the samplers, which are then pulled by a system consisting of a winch, cable, and pulley. Specifically, the system releases a cable via a winch; the cable loops around a pulley at the top of the sampling chamber and its end is connected to the water sampler. When the winch starts, the cable is retracted under the guidance of the pulley, slowly pulling the water sampler away from the winch into the sampling chamber. However, while this system functionally meets the basic requirements for transferring water samplers, it still presents some inconveniences in actual operation. First, the cable must be connected to the water sampler before each transfer, but the connection point is usually located at the bottom of the transfer trolley, making connection and disconnection inconvenient. Second, because the pulling can only be done in one direction, the lack of control in the opposite direction can lead to difficulty in stopping the device and potential danger due to overshoot.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the beneficial effects of the technical solution provided in this application include at least the following:

[0025] The water sampler transfer device of this application can realize the function of transferring the water sampler inside and outside the sampling room. When transferring the water sampler from outside the sampling room to inside the sampling room, the first area of ​​the transfer platform is the sampling room, and the second area is outside the sampling room. The transfer trolley first loads the water sampler in the second area. At this time, the connecting component is also set in the second area. Its push-pull rod is embedded in the slot of the transfer trolley through the locking block, so that the push-pull rod and the transfer trolley are fixed in their moving direction. Then, the drive mechanism works, and the drive component drives the roller to rotate. Since the two ends of the pull rope are wound in opposite directions on the roller, the two ends of the pull rope can be released and pulled back respectively when the roller rotates. The pull rope changes the direction of force through the fixed pulley, so that when the end connected to the fixed pulley is pulled back, it can pull the rocker arm, the push-pull rod and the transfer trolley to move towards the sampling room until the water sampler is transferred to the sampling room. When the water sampler transfer device of this application transfers the water sampler from the sampling room to the outside of the sampling room, the roller rotates in the opposite direction to perform rope winding and unwinding operations at both ends of the pull rope. The pull rope pulls the transfer trolley to move towards the second area until the water sampler is transferred to the outside of the sampling room.

[0026] The water sampler transfer device of this application can control the movement of the transfer trolley in both directions, making it easier to stop the transfer trolley and reducing the risk of overshoot.

[0027] The water sampler transfer device of this application can quickly connect the transfer trolley and the drive mechanism through a connecting component. The push-pull rod cooperates with the slot of the transfer trolley through a locking block to achieve quick connection and disconnection, making operation more convenient.

[0028] The water sampler transfer device of this application, by winding the pull rope around the rocker arm, can compensate for the difference in the length of the pull rope when it is wound up and unwound at both ends by swinging the rocker arm, thus avoiding excessive or insufficient tension of the pull rope, thereby extending the service life of the pull rope and improving the reliability of the water sampler transfer device.

[0045] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0047] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0049] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0050] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0051] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0052] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0053] In order to transfer the salvaged water sampler to the sampling room, the existing transfer platform has a fixed pulley installed in the sampling room. The cable on the winch in the winch workshop goes around the fixed pulley and is connected to the water sampler. Although it can pull the water sampler into the sampling room, the cable needs to be connected to the water sampler before each transfer. However, the existing cable connection to the water sampler is not convenient enough.

[0054] To address the aforementioned technical problems, this embodiment provides a water sampler transfer device. (See reference...)

Figure 6 yes Figure 5 A schematic diagram of section C. Figure 7 This is a perspective view of the connecting components in an embodiment of this application. Figure 8 yes Figure 7 A schematic diagram of section D.

[0055] A water sampler transfer device, such as Figure 1 and Figure 3 As shown, the water sampler 6 is used to move between the first region 51 and the second region 52 of the transfer platform 5. The water sampler transfer device includes: a track 1, a transfer trolley 2, a connecting component 3 and a drive mechanism 4.

[0056] Track 1 is set on the transfer platform 5 and extends in a straight line to the first region 51 and the second region 52.

[0057] The transfer trolley 2 is movably mounted on the track 1 and is fixedly mounted with a connecting seat 21, which is provided with a slot 211.

[0058] The connecting component 3 is a disengagement device, including a push-pull rod 31 and a rocker arm 32. One end of the push-pull rod 31 is provided with a locking block 311, which is detachably embedded in the locking groove 211 so that the push-pull rod 31 is detachably connected to the transfer trolley 2. The rocker arm 32 is oscillatingly connected to the other end of the push-pull rod 31 through a swing shaft 33, which is perpendicular to the straight line direction.

[0059] The drive mechanism 4 includes a fixed pulley 41, a pull rope 42, and a drive assembly 43. The fixed pulley 41 is rotatably mounted on the track 1. The drive assembly 43 includes a rotatable roller 431, which is rotatably disposed in the second region 52 and parallel to the swing shaft 33. The two ends of the pull rope 42 are wound around the roller 431 in opposite directions, and the middle part of the pull rope 42 passes over the fixed pulley 41 and is wound around the rocker arm 32. The drive assembly 43 can be an existing winch, and its output shaft is connected to the roller 431 for transmission.

[0060] In some implementations, see Figure 7 and Figure 8 As shown, the connecting seat 21 is provided with two spaced-apart limiting blocks 212, which form a slot 211 with the transfer trolley 2. One end of the push-pull rod 31 is positioned between the two limiting blocks 212. The slot 211 formed by the limiting blocks 212 and the transfer trolley 2 allows for quick and accurate positioning of the push-pull rod 31 on the connecting seat 21, greatly improving installation efficiency and ensuring the accuracy of the push-pull rod 31's installation position, thus laying the foundation for the stable operation of the subsequent device.

[0061] See Figure 8 As shown, in some embodiments, both limiting blocks 212 are provided with pin holes 213, and the connecting assembly 3 further includes a pin 214, which is movably inserted into the pin holes 213 of the two limiting blocks 212. One end of the push-pull rod 31 is disposed between the connecting seat 21, the pin 214, and the limiting blocks 212. The pin 214 provides additional limiting measures for the installation of the push-pull rod 31, enhances the connection strength between the push-pull rod 31 and the connecting seat 21, effectively prevents the push-pull rod 31 from loosening or falling off during use, and improves the reliability and safety of the entire device.

[0062] In some implementations, see Figure 8As shown, the cross-section of the pin hole 213 perpendicular to its length includes a circular area 215 and an anti-rotation area 216 disposed at the edge of the circular area 215. The pin 214 has a handle 217 at one end and a plug 218 at the other end. The cross-sectional shape of the plug 218 perpendicular to its length is the same as the cross-sectional shape of the pin hole 213 perpendicular to its length, and it is disposed within at least one of the pin holes 213 to prevent the pin 214 from rotating. The cross-sectional structure formed by the circular area 215 and the anti-rotation area 216 of the pin hole 213 and the plug 218 ensures that the pin 214 can be firmly fixed in the desired position after being inserted into the pin hole 213, and will not rotate due to external force. This further enhances the stability of the connection between the push-pull rod 31 and the connecting seat 21, avoiding the problem of loosening of the connection caused by the rotation of the pin 214.

[0063] Further, see Figure 8 As shown, the anti-rotation zone 216 is horizontally oriented away from the circular zone 215. The handle 217 is rod-shaped and horizontally positioned. Both ends of the handle 217 extend towards opposite sides of the pin 214 with different lengths, giving the pin a tendency to rotate. The horizontally positioned handle 217 facilitates gripping and operation by the operator. The different lengths at both ends shift the center of gravity to one side in a horizontal position, thus tending to rotate the pin 214. This rotational tendency allows the plug 218 to abut against the inside of the pin hole 213, thereby improving the stability of the pin 214 and reducing the risk of the pin 214 dislodging from the pin hole 213.

[0064] To avoid damage to the paint or appearance of components due to rigid fit between parts, please refer to... Figure 8 As shown, a pad 219 is provided between the locking block 311 and the transfer trolley 2, the limiting block 212, and the connecting seat 21, and a pad 219 is provided between the push-pull rod 31 and the connecting seat 21, the limiting block 212, and the pin 214. The pad 219 can be a nylon pad. Simultaneously, the pad 219 effectively disperses the pressure between components, reduces wear between components, and extends the service life of the device. The pad 219 also acts as a buffer, reducing vibration and noise generated during operation, and improving the smoothness and comfort of the device's operation.

[0065] In some implementations, see Figure 4 and Figure 6 As shown, a pair of lugs 34 are fixedly mounted on the top of the push-pull rod 31, and the upper end of the rocker arm 32 is rotatably connected to the lugs 34 via the swing shaft 33. The connection between the lugs 34 and the swing shaft 33 allows the rocker arm 32 to swing flexibly relative to the push-pull rod 31.

[0066] See Figure 6and Figure 7 As shown, in some embodiments, a mounting plate 35 is fixedly provided at the end of the push-pull rod 31 near the rocker arm. The mounting plate 35 and the rocker arm 32 are provided with through holes 36. The connecting assembly 3 also includes an adjusting bolt 37, which is movably inserted through the through holes 36 in the mounting plate 35 and the rocker arm 32, with both ends extending to the outside of the mounting plate 35 and the rocker arm 32, respectively. The adjusting bolt 37 has stop portions 38 on both sides of the mounting plate 35 and the rocker arm 32 to limit the swing range of the rocker arm 32. The stop portions 38 can be integrally formed on the head of the adjusting bolt 37 or a nut threaded onto the adjusting bolt 37. The adjusting bolt 37 and the stop portions 38 can precisely control the swing angle of the rocker arm 32, preventing excessive swing of the rocker arm 32 from causing device damage or operational errors. Simultaneously, this design allows for adjustment of the swing range of the rocker arm 32 according to actual needs, improving the adaptability and flexibility of the device.

[0067] In some implementations, see Figure 7 As shown, the rocker arm 32 is equipped with a circular shaft 39, and the pull rope 42 is wound around the circular shaft 39. An anti-detachment plate 321 is provided at the bottom of the circular shaft 39 to prevent the pull rope 42 from detaching from the bottom of the circular shaft 39. The design of the anti-detachment plate 321 effectively prevents the pull rope 42 from falling off the circular shaft 39 during use, ensuring a reliable connection between the pull rope 42 and the rocker arm 32, guaranteeing the normal operation of the water sampler transfer device, and avoiding operational interruptions and safety hazards caused by the pull rope 42 falling off.

[0068] See Figure 7 As shown, in some embodiments, a clamp 322 is provided on the outer side of the circular shaft 39, and the pull rope 42 is wound around the rocker arm 32 portion located inside the clamp 322. The two ends of the pull rope 42 wound around the rocker arm 32 portion are respectively led out from the top and bottom of the clamp 322. The clamp 322 provides further constraint on the pull rope 42, making its winding on the circular shaft 39 more neat and stable, reducing the swaying and tangling of the pull rope 42, and improving its service life and operational accuracy. Simultaneously, the design of the pull rope 42 leading out from the top and bottom of the clamp 322 also facilitates the arrangement and operation of the pull rope 42.

[0069] When using the water sampler transfer device of this application, the first time the rope is wound, the pull rope 42 can be wound around the roller 431 near the roller motor end, passing through the fixed pulley 41 on the track. At this time, the rocker arm 32 needs to be fixed in the middle position with the adjusting bolt 37. The pull rope 42 is wound around the rocker arm 41 several times and fixed with buckles or clamps to increase friction. Then it is wound back to the roller 431 in the opposite direction. The adjusting bolt 37 of the rocker arm 32 can be loosened after maintaining the tension of the pull rope 42 (not in a slack state).

[0070] The water sampler transfer device of this application can realize the function of transferring the water sampler inside and outside the sampling room. When transferring the water sampler from outside the sampling room to the sampling room, the first area 51 of the transfer platform 5 is the sampling room, and the second area 52 is the outside of the sampling room. The transfer trolley 2 first loads the water sampler in the second area 52. At this time, the connecting component 3 is also set in the second area 52. Its push-pull rod 31 is embedded in the slot 211 of the transfer trolley 2 through the locking block 311, so that the push-pull rod 31 and the transfer trolley 2 are fixed in their moving direction. Then, the drive mechanism 4 works, and the drive component 43 drives the roller 431 to rotate. Since the two ends of the pull rope 42 are wound in opposite directions on the roller 431, the roller 431 can release and retract the two ends of the pull rope 42 respectively when rotating. The pull rope 42 changes the direction of force through the fixed pulley 41, so that when the end connected to the fixed pulley 41 retracts the rope, it can pull the rocker arm 32, the push-pull rod 31 and the transfer trolley 2 to move towards the sampling room until the water sampler is transferred to the sampling room. When the water sampler transfer device of this application transfers the water sampler from the sampling room to the outside of the sampling room, the roller 431 rotates in the opposite direction to perform rope winding and unwinding operations at both ends of the pull rope 42. The pull rope 42 pulls the transfer trolley 2 to move towards the second area 52 until the water sampler is transferred to the outside of the sampling room.

[0071] The water sampler transfer device of this application can quickly connect the transfer trolley 2 and the drive mechanism 4 via the connecting component 3. The push-pull rod 31 engages with the slot 211 of the transfer trolley 2 via the locking block 311, enabling quick connection and disconnection, making operation more convenient. At the same time, the pull rope 42 can be a fiber optic cable, which has a certain degree of elasticity and can loosen the buckle to release the tension of the cable for removal of the release device.

[0072] The water sampler transfer device of this application, by winding the pull rope 42 around the rocker arm 32, can compensate for the difference in the length of the pull rope 42 when it is wound up and unwound at both ends by swinging the rocker arm 32, thereby avoiding excessive or insufficient tension of the pull rope 42, extending the service life of the pull rope 42, and improving the reliability of the water sampler transfer device.
