This addresses the technical problem that existing technologies use multiple samplers for synchronous sampling in order to improve sampling efficiency. Each sampler is controlled by a solenoid valve, but the solenoid valve is not very stable when working underwater and is easily damaged, which affects the sampling process.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a hammer-type synchronous sampling device, comprising: support; Multiple sampling components are spaced apart on the support along a first direction. Each sampling component includes a reel, a rope, a sampler, and a gravity hammer. The reel is rotatably mounted on the support.

It has a non-triggered state that is fixed to the support and a triggered state that is detached from the support, slides along the rope, and triggers the sampler. A first connector connects to the plurality of samplers; and A first power unit is connected to the reel to drive the reel to rotate.

[0007] In some embodiments, a second connector is provided between two adjacent reels. The second connector is movably disposed on the bracket to have a connected state connecting two adjacent reels and a separated state separating from at least one of the reels. During winding, the second connector is in the connected state so that the multiple reels rotate synchronously.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To address the technical problem that existing technologies use multiple samplers simultaneously to improve sampling efficiency, each controlled by a solenoid valve, but these solenoid valves are unstable and prone to damage underwater, affecting the sampling process, this invention provides a hammer-type synchronous sampling device. Multiple samplers can sample simultaneously, improving sampling efficiency. Furthermore, sampling is achieved by using a gravity hammer to strike the samplers, i.e., using a hammer-based control method, resulting in strong controllability, low failure rate, and resistance to damage.

[0022] Please see Figure 1 , Figure 1 This is a schematic diagram of the hammer-type synchronous sampling device in one embodiment of the present invention.

[0023] This utility model provides a hammer-type synchronous sampling device, including a support 1, multiple sampling components 2, a first connector 3, and a first power device 4. The multiple sampling components 2 are spaced apart on the support 1 along a first direction. Each sampling component 2 includes a reel 21, a rope 22, a sampler 23, and a gravity hammer 24. The reel 21 is rotatably mounted on the support 1. One end of the rope 22 is wound around the reel 21, and the other end of the rope 22 is connected to the sampler 23. The gravity hammer 24 is sleeved on the rope 22 and movably connected to the support 1, having a non-triggered state fixed to the support 1 and a triggered state in which it detaches from the support 1, slides along the rope 22, and triggers the sampler 23. The first connector 3 connects the multiple samplers 23. The first power device 4 is connected to the reel 21 to drive the reel 21 to rotate.

[0024] In this embodiment, please refer to Figures 1 to 3The support 1 is mounted on the hull, and multiple reels 21 are spaced apart along a first direction on the support 1. One end of the rope 22 is wound around the reel 21, and the other end is connected to the sampler 23. The gravity hammer 24 is slidably mounted on the rope 22. The reel 21 in the middle is the main reel, and the other reels 21 are auxiliary reels. The first power device 4 is connected to the main reel. In actual use, the sampler 23 is first opened, and the gravity hammer 24 is moved to the end of the rope 22 near the reel 21 and fixed. When the device moves to the designated water area, the first power device 4 drives the main reel to unwind, and multiple samplers 23 move downwards simultaneously into the river. The rope 22 on the auxiliary reel is passively unwound under the drive of the sampler 23. When multiple samplers 23 extend to a set depth, the gravity hammer 24 is dropped. The gravity hammer 24 moves downward to abut against the sampler 23 and triggers the sampler 23 to close, thus achieving the sampling of sediment. Finally, the first power device 4 drives the main reel to rewind, and the other reels 21 assist in the rewinding, thus completing the entire sampling process. In this application, multiple samplers 23 can sample simultaneously, improving sampling efficiency. At the same time, the sampling is carried out by using the gravity hammer 24 to trigger the sampler 23, that is, by using a hammering method for control, which has strong controllability, low failure rate, and is not easily damaged.

[0025] In this embodiment, please refer to Figure 5 and Figure 6 The first connector 3 connects multiple samplers 23 to form an integral structure, ensuring that the multiple samplers 23 operate synchronously, that the multiple samplers 23 can sample at the same depth, and that the multiple samplers 23 sample simultaneously, thereby improving sampling efficiency.

[0026] In this embodiment, the main reel serves two purposes: firstly, to wind up and unwind the rope 22, and secondly, to guide the gravity hammer 24. The auxiliary reels, on the other hand, only serve to guide the gravity hammer 24. That is, the middle reel 21 actively winds up and unwinds the rope, while the other reels 21 assist in winding up and unwinding the rope. This avoids the situation where multiple reels 21 simultaneously wind up and unwind the rope, resulting in uneven unwinding and inconsistent heights of the multiple samplers 23.

[0027] In this embodiment, please refer to Figure 5 and Figure 6The sampler 23 includes a cylindrical body 231, two door panels 232, a first elastic element, and a locking element 233. The cylindrical body 231 has a sampling channel. The upper ends of the two door panels 232 are rotatably mounted at opposite ends of the sampling channel. The first elastic element is disposed within the sampling channel, and its two ends are connected to the two door panels 232. The first elastic element drives the two door panels 232 to rotate toward each other to close the sampling channel. The locking element 233 is movably mounted on the cylindrical body 231 in a vertical direction. The locking element 233 has a locked state where it moves upward and connects to the two door panels 232, and an unlocked state where it moves downward and separates from the two door panels 232. In the first state, the rope 22 is connected to the cylinder 231 and is corresponding to the locking member 233. In specific use, firstly, the two door panels 232 are rotated to open the sampling channel, and the door panels 232 and the locking member 233 are abutted in the vertical state. Then, the sampler 23 is lowered to a set depth for sampling. After waiting for a period of time, the gravity hammer 24 is released. The gravity hammer 24 moves downward along the rope 22 until it abuts against the locking member 233. Under the hammering of the gravity hammer 24, the locking member 233 moves downward and is in the unlocked state. At this time, the two door panels 232 close the sampling channel under the elastic force of the first elastic member, thereby completing the sampling.

[0028] It is understood that the sampler 23 is existing technology, and its structure and usage will not be described in detail here.

[0029] When the sampling is completed and the winding is performed, the winding method of the auxiliary reel is not limited. It can be that the auxiliary reel is manually rotated to wind up while the main reel is driven by the first power device 4. Alternatively, multiple reels 21 can be connected in series through a connecting structure so that the multiple reels 21 rotate synchronously, thereby using the first power device 4 to wind up synchronously. At this time, the sampling is completed and there is no need to consider the situation of uneven winding.

[0030] In this embodiment, please refer to Figures 2 to 4A second connector 5 is provided between two adjacent reels 21. The second connector 5 is movably disposed on the bracket 1, having a connected state connecting two adjacent reels 21 and a separated state separating from at least one reel 21. During winding, the second connector 5 is in the connected state, allowing multiple reels 21 to rotate synchronously. Each pair of adjacent reels 21 is provided with a second connector 5, allowing multiple reels 21 to be connected in series. The second connector 5 is detachable from the reel 21. During unwinding, the second connector 5 moves to separate from at least one reel 21, being in the separated state, where the multiple reels 21 are relatively independent. During winding, the second connector 5 connects two adjacent reels 21, being in the connected state, where the multiple reels 21 form a whole and can rotate synchronously, achieving synchronous winding and reducing labor intensity during winding.

[0031] The second connector 5 can take many different forms; In one embodiment, slots are provided on the opposite sides of two adjacent reels 21; the second connector 5 includes a plug-in that is inserted into the two slots.

[0032] Specifically, the slots are arranged radially, and one end of the slot extends to the outer periphery of the reel 21 to form an opening. The two slots correspond to each other, and the connector is detachably inserted into the two slots. When unwinding, the connector is removed, and when rewinding, the connector is inserted into the two slots, thereby connecting the two reels 21 together.

[0033] Furthermore, in order to improve the connection strength, each of the reels 21 is provided with a plurality of slots, and the plurality of slots are arranged at intervals along the circumference of the reel 21. Correspondingly, a plurality of plug-in members are provided.

[0034] In this embodiment, please refer to Figures 2 to 4 The reel 21 has a rotating shaft 211 in the middle, which is rotatably mounted on the bracket 1. The rotating shaft 211 has external splines 212 at both ends. The second connecting member 5 includes a spline sleeve 51, which is slidably mounted on the bracket 1 along the first direction and located between the two rotating shafts 211. The spline sleeve 51 is splinedly engaged with the rotating shaft 211.

[0035] Specifically, the reel 21 has a rotating shaft 211 in the middle, which extends along a first direction and has protruding ends. The reel 21 is rotatably mounted on the bracket 1 via the rotating shaft 211. Multiple rotating shafts 211 are coaxially arranged and spaced apart. The ends of the rotating shafts 211 are provided with external splines 212. The second connecting member 5 is a spline sleeve 51 adapted to the external spline 212. The spline sleeve 51 is slidably mounted on one of the rotating shafts 211. When winding, the spline sleeve 51 slides towards another rotating shaft 211 and engages with the spline of the other rotating shaft 211, thereby connecting two adjacent rotating shafts 211 using the spline sleeve 51 to ensure that multiple rotating shafts 211 rotate synchronously.

[0036] In this embodiment, please refer to Figure 4 The first power unit 4 includes a transmission structure and a geared motor 41. The geared motor 41 is mounted on the bracket 1. The main shaft of the geared motor 41 is connected to the rotating shaft 211 through the rotating shaft 211 structure, thereby driving the reel 21 to rotate through the geared motor 41.

[0037] Specifically, the transmission structure includes a driving gear 42 and a driven gear 43. The driving gear 42 is rotatably mounted on the bracket 1 along the axis in the first direction. The main shaft of the reduction motor 41 is connected to the driving gear 42. The driven gear 43 is fixedly connected to the rotating shaft 211. The driving gear 42 and the driven gear 43 mesh, thereby driving the reel 21 to rotate through gear transmission.

[0038] In another embodiment, the transmission structure includes two synchronous pulleys and a synchronous belt. The two synchronous pulleys are respectively mounted on the main shaft of the geared motor 41 and the rotating shaft 211. The synchronous belt is connected to the two synchronous pulleys, thereby driving the reel 21 to rotate through the synchronous belt.

[0039] In another embodiment, the hammer-type synchronous sampling device further includes a second power unit connected to the remaining reels 21 to drive them to rotate synchronously, wherein the rotational speed of the remaining reels 21 is less than or equal to the rotational speed of the reel 21 located in the middle. The first power unit 4 drives the reel 21 located in the middle, while the remaining reels 21 are driven by the second power unit. This arrangement reduces the labor intensity during winding.

[0040] Specifically, the middle reel 21 is provided with a clearance hole in the middle part. The second power device includes a drive motor and a connecting shaft. The diameter of the connecting shaft is smaller than the diameter of the clearance hole. The connecting shaft is rotatably mounted on the bracket 1 along the axis in the first direction, and the connecting shaft passes through the clearance hole. The connecting shaft is fixedly connected to the other reels 21. The main shaft of the drive motor is connected to one end of the connecting shaft, thereby driving the other reels 21 to rotate through the connecting shaft.

[0041] In this embodiment, please refer to Figure 7 The gravity hammer 24 has a through hole in the middle, through which the rope 22 passes. This arrangement ensures a secure installation and prevents the gravity hammer 24 from easily coming loose.

[0042] In this embodiment, please refer to Figures 5 to 6 To facilitate assembly and subsequent maintenance, the first connector 3 is detachably connected to the multiple samplers 23.

[0043] Specifically, a boss 2311 is formed on the upper side of the sampler 23, and the boss 2311 is provided with a threaded hole. The first connector 3 is provided with a plurality of through holes, and the plurality of through holes correspond one-to-one with the plurality of threaded holes. The first connector 3 is connected to the plurality of samplers 23 by bolts.

[0044] In this embodiment, please refer to Figures 1 to 3 Since the bracket 1 is installed on the hull, and the upper end of the bracket 1 is bent outward and extends outside the hull, while the reel 21 is installed at the lower end of the bracket 1, in order to guide the rope 22, the bracket 1 is provided with a plurality of pulleys 11 at intervals along the first direction, and the plurality of pulleys 11 correspond one-to-one with the plurality of ropes 22, and the rope 22 is wound around the corresponding pulley 11.

[0045] The specific form of fixing the gravity hammer 24 is not limited. In one embodiment, the bracket 1 is provided with a hook hole near the pulley 11, and the gravity hammer 24 is provided with a hook. The gravity hammer 24 is fixed by hanging in the hook hole through the hook. When in use, the hook can be taken out, which is convenient to operate.

[0046] In this embodiment, please refer to Figure 1 and Figure 7 The hammer-type synchronous sampling device also includes an electromagnet 6, which is disposed on the bracket 1 and located below the pulley 11, so that when the electromagnet 6 is energized, the electromagnet 6 magnetically engages with the plurality of gravity hammers 24. The gravity hammers 24 are made of iron, and the fixing and loosening of the gravity hammers 24 are achieved by turning the electromagnet 6 on and off.

[0047] In this embodiment, please refer to Figure 1 In order to increase the counterweight of the multiple samplers 23, the hammer-type synchronous sampling device also includes a lead weight 7, which is located at the bottom of the sampler in the middle of the multiple samplers.

[0048] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail below: In practical use, the electromagnet 6 is energized, and the gravity hammer 24 is attracted and fixed to the electromagnet 6. Then, the two door panels 232 are rotated to open the sampling channel, and the door panels 232 are connected to the locking member 233. The sliding spline sleeve 51 is in the separated state. At this time, the multiple reels 21 are relatively independent. The reduction motor 41 is started. The reduction motor 41 drives the middle reel 21 to unwind through the meshing of the driving gear 42 and the driven gear 43. The multiple samplers 23 move downwards synchronously into the river. The ropes 22 on the remaining reels 21 are passively unwound under the action of their respective samplers 23 until they reach the set depth. Then, the electromagnet 6 is de-energized, and the gravity hammer 24 is fixed to the electromagnet 6. Under the influence of gravity, the hammer 24 moves downward along the rope 22 until it abuts against the locking member 233. Under the hammering of the hammer 24, the locking member 233 moves downward and enters the unlocked state. At this time, the two door panels 232 close the sampling channel under the elastic force of the first elastic member, thereby completing the sampling. Then, the spline sleeve 51 is slid to the connected state, and the reduction motor 41 drives multiple reels 21 to rotate synchronously for winding, completing the sampling. In this application, multiple samplers 23 can sample synchronously, improving the sampling efficiency. At the same time, the sampling is carried out by using the hammer 24 to strike the sampler 23, that is, by using a hammering method for control, which has strong controllability, low failure rate, and is not easily damaged.
