Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy project sampling, and in particular relates to a sampling device for water conservancy project investigation. Background Art

[0002] In the investigation and sampling of water conservancy projects, a sampling device is usually used. The sampling device generally consists of a sampling probe, a sampling tube, a drive mechanism, a control component, and a sample collection container. The sampling probe can penetrate into different strata or water bodies of the water conservancy project and accurately collect samples. The sampling tube connects the sampling probe and the sample collection container to ensure the smooth transmission of the collected samples. The sample collection container is used to safely store the collected samples for subsequent analysis and research. This sampling device is easy to carry and operate, and can efficiently obtain representative samples in the complex environment of water conservancy projects, providing an important basis for the investigation, design and construction of water conservancy projects.

[0003] A Chinese patent with application number CN202322834552.X discloses a sampling device for water conservancy engineering surveys, including a bottom plate and a storage tank. A feed box is fixedly connected to one side of the outer wall of the storage tank. A servo motor and a gearbox are respectively provided on one end face of the feed box. The output end of the servo motor is connected to a transmission belt, one end of the transmission belt is connected to the gearbox, the output end of the gearbox extends into the interior of the feed box and is fixedly connected to a driving shaft, and the outer wall of the driving shaft is connected to a conveyor belt. The utility model is suitable for use in large-scale sampling work. Compared with smaller sampling devices, it does not require workers to frequently insert the device into the soil for sampling work, which greatly reduces the labor intensity of workers. In addition, a sample storage structure is provided, and there is no need for a manual driving cart to follow the rear end of the sampling device.

[0004] In this solution, although the effect of rapid storage is achieved, when using it, the staff needs to push the device to the appropriate position, and the device can only sample the edges and adjust the distance, which makes sampling more limited. In addition, the entire device needs to be pushed continuously to move at different positions, which is time-consuming and labor-intensive. It is different from multi-directional sampling at the same position, which reduces work efficiency. Utility Model Content

[0005] The main technical problem to be solved by the utility model is to provide a sampling device for water conservancy engineering survey which has a simple overall structure, can automatically sample water bodies within a large range, can adjust the sampling range, improve work efficiency, and enhance use effect.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A sampling device for use in water conservancy engineering surveys includes a support rod assembly, a mounting plate fixedly mounted on the upper end of the support rod assembly, a telescopic rod fixedly connected to the mounting plate, a driving device for driving the telescopic rod to rotate provided at a position of the support rod assembly near the mounting plate, a fixing frame fixedly mounted on the telescopic end of the telescopic rod, a line-releasing device provided in the fixing frame, and a sampling bucket assembly bolted to the end of the line-releasing device;

[0008] The sampling barrel assembly includes a hanger bolted to the end of the line-releasing device, a liquid barrel fixedly mounted on the other end of the hanger, a liquid inlet plate fixedly mounted on the outer bottom surface of the liquid barrel, and a sleeve fixedly mounted at a position on the inner bottom surface of the liquid barrel corresponding to the liquid inlet plate;

[0009] A sealing plate is slidably connected in the sleeve, and a spring is fixedly installed between the sealing plate and the liquid inlet plate;

[0010] A draw rope is bolted to a middle position of the sealing plate away from the spring surface.

[0011] The following is a further optimization of the above technical solution by the present invention:

[0012] The support rod assembly includes a mounting sleeve rod, a chassis is fixedly mounted at the end of the mounting sleeve rod close to the ground, a plurality of ground cones are hinged at the edge of the chassis, and the plurality of ground cones are arranged in a circular array with the center of the chassis.

[0013] Further optimization: a top plate is fixedly installed at the end of the mounting sleeve rod away from the ground cone, a central shaft is rotatably connected to the top plate through a bearing, and a first gear is sleeved on the outer surface of the central shaft.

[0014] Further optimization: the driving device includes a motor mounting plate fixedly mounted on the outer surface of the mounting sleeve rod, and a first motor is fixedly mounted on the motor mounting plate.

[0015] Further optimization: a rotating shaft is fixedly connected to the power output end of the first motor, a second gear is sleeved on the outer surface of the rotating shaft, and the second gear is meshed with the first gear at the same time.

[0018] Further optimization: the liquid inlet plate has a plurality of first filter holes in a circular array.

[0019] Further optimization: sealant is adhered to the edge of the sealing plate.

[0020] Further optimization: rope support blocks are fixedly installed on the mounting ends of the fixed frame and the telescopic rod respectively, the two rope support blocks are in the same plane, and the other end of the rope passes through the two rope support blocks and is bolted to a pull ring.

[0021] The utility model adopts the above technical solution, with ingenious conception and reasonable structure. The first motor drives the telescopic rod to rotate, and the telescopic rod drives the sampling bucket assembly to extend and retract. The second motor drives the rope to move down and recover, and then drives the sampling bucket assembly to move down and up. At the same time, under the action of multiple counterweights, it can ensure that the liquid bucket quickly sinks to the depth of the required sampling water body, realize multi-directional and multi-angle adjustment of the liquid bucket, expand the sampling range, and meet the water sample collection needs in different environments.

[0022] When taking samples, pull the pull ring to move the sealing plate up, and the water sample liquid can pass through the first filter hole and the second filter hole into the liquid storage barrel. When the required amount of water sample liquid is met, release the pull ring, and the spring drives the sealing plate to move down, so that the water sample liquid in the liquid storage barrel can be sealed to prevent leakage. The operation is simple and convenient to use.

[0032] like Figure 1-7 As shown: A sampling device for water conservancy engineering survey, including a support rod assembly 1, a mounting plate 3 is fixedly mounted on the upper end of the support rod assembly 1, a telescopic rod 4 is fixedly connected to the mounting plate 3, a driving device 2 for driving the telescopic rod 4 to rotate is provided at a position of the support rod assembly 1 near the mounting plate 3, a fixing frame 5 is fixedly mounted on the telescopic end of the telescopic rod 4, a line-releasing device 6 is provided in the fixing frame 5, and a sampling bucket assembly 7 is bolted to the end of the line-releasing device 6;

[0033] The sampling barrel assembly 7 includes a hanger 80 bolted to the end of the pay-off device 6, and a liquid barrel 71 is fixedly mounted on the other end of the hanger 80. A liquid inlet plate 72 is fixedly mounted on the outer bottom surface of the liquid barrel 71, and a sleeve 77 is fixedly mounted on the inner bottom surface of the liquid barrel 71 at a position corresponding to the liquid inlet plate 72;

[0034] A sealing plate 74 is slidably connected in the sleeve 77, and a spring 73 is fixedly installed between the sealing plate 74 and the liquid inlet plate 72;

[0035] A pull rope 76 is bolted to the sealing plate 74 at a middle position away from the surface of the spring 73 .

[0036] In this embodiment, the support rod assembly 1 is directly placed at the land edge of the water body to be sampled.

[0037] like Figure 2-3 As shown, the support rod assembly 1 includes a mounting sleeve rod 11, and a chassis 13 is fixedly installed at the end of the mounting sleeve rod 11 close to the ground.

[0038] A plurality of ground cones 12 are hinged at the edge of the chassis 13 , and the plurality of ground cones 12 form a circular array with the center of the chassis 13 .

[0039] Damping is provided at the hinged joints of the multiple ground cones 12 and the chassis 13 to ensure that the ground cones 12 can rotate at any angle. In the prior art, controlling the rotation angle of the ground cones 12 by damping is well known and widely used, and will not be described in detail here.

[0040] During use, the plurality of ground cones 12 are all rotated counterclockwise to a certain angle and then inserted into the ground to ensure the stability of the mounting sleeve 11 during installation and use.

[0041] A top plate 14 is fixedly mounted on the end of the mounting sleeve rod 11 away from the ground cone 12 , and a central shaft 15 is rotatably connected to the top plate 14 via a bearing.

[0042] A first gear 16 is sleeved on the outer surface of the central shaft 15 .

[0043] The mounting plate 3 is fixedly mounted at the other end of the central axis 15 .

[0044] The driving device 2 includes a motor mounting plate 22 fixedly mounted on the outer surface of the mounting sleeve rod 11 , and the motor mounting plate 22 is also located near the first gear 16 .

[0045] The first motor 21 is fixedly mounted on the motor mounting plate 22 , and the power output end of the first motor 21 is arranged upward.

[0046] A rotating shaft 23 is fixedly connected to the power output end of the first motor 21 . A second gear 24 is sleeved on the outer surface of the rotating shaft 23 . The second gear 24 is meshed with the first gear 16 .

[0047] With this design, the first motor 21 is started, and the power output end of the first motor 21 drives the second gear 24 to rotate, which in turn drives the first gear 16 to rotate, and at the same time drives the central shaft 15 and the mounting plate 3 to rotate, and the telescopic rod 4 rotates following the mounting plate 3.

[0048] In this embodiment, the telescopic rod 4 is electrically driven.

[0049] In addition to this embodiment, the telescopic rod 4 can also be telescopically driven by pneumatic or hydraulic means.

[0050] The pay-off device 6 includes a rotating roller 62 rotatably connected to the inner side wall of the fixed frame 5 through a bearing.

[0051] One end of the rotating roller 62 away from the telescopic rod 4 passes through the side wall of the fixing frame 5 and is fixedly connected to the power output end of the second motor 61 .

[0052] The second motor 61 is also fixedly mounted on the fixing frame 5 .

[0053] A rope 63 is wound around the outer surface of the rotating roller 62 , wherein one end of the rope 63 is fixedly connected to the rotating roller 62 , and the other end of the rope 63 is bolted to the sampling barrel assembly 7 .

[0054] In this design, the second motor 61 is started, and the power output end of the second motor 61 rotates to drive the rotating roller 62 to rotate, and then the rope 63 is retracted and released on the rotating roller 62, so that the sampling barrel assembly 7 is moved upward or downward.

[0055] like Figure 4-7 As shown together, the other end of the wire rope 63 is bolted to the middle position of the hanger 80 .

[0056] The liquid inlet plate 72 has a plurality of first filter holes 720 in a circular array, and the water to be sampled can enter through the first filter holes 720 .

[0057] A sealant 75 is adhered to the edge of the sealing plate 74 .

[0058] One end of the spring 73 is fixedly mounted on the liquid inlet plate 72 , and the other end of the spring 73 is fixedly mounted on the sealing plate 74 .

[0059] When the spring 73 is in a natural state, the area between the liquid inlet plate 72 and the sealing plate 74 in the sleeve 77 is set as a liquid storage cavity. At this time, the liquid storage cavity is not connected to the interior of the liquid storage barrel 71.

[0060] The outer surface of the sleeve 77 is provided with a plurality of second filter holes 770 in an annular array above the liquid storage chamber.

[0061] When in use, the sampling barrel assembly 7 is placed in a body of water, and the water first passes through the first filter hole 720 and enters the liquid storage cavity.

[0062] like Figure 2 As shown, a pull rope support block 78 is fixedly mounted on the mounting end of the fixed frame 5 and the telescopic rod 4 respectively, and the two pull rope support blocks 78 are in the same plane.

[0063] The other end of the pull rope 76 passes through two pull rope support blocks 78 and is bolted to a pull ring 79. With this design, the pull ring 79 is located at the installation position of the sleeve rod 11, which is easy to operate.

[0064] During use, when the liquid storage chamber is filled with liquid, the pull ring 79 is pulled to move the sealing plate 74 upward along the inner wall of the sleeve 77. In this way, the liquid enters the liquid storage barrel 71 through the second filter hole 770, that is, the liquid storage chamber is connected to the interior of the liquid storage barrel 71. When the required liquid volume is reached, the pull ring 79 is released. Under the action of the spring 73, the sealing plate 74 moves downward. Under the sealing action of the sealant 75, the connection between the liquid storage chamber and the liquid storage barrel 71 is sealed and disconnected, and the water entering the liquid storage barrel 71 will not leak out.

[0065] A control cabinet for controlling the operation of the device is also fixedly mounted on the outer surface of the mounting sleeve rod 11 (not shown in the figure). A control system is provided in the control cabinet.

[0066] The control ends of the first motor 21 and the second motor 61 are electrically connected to the control system through wires, and the control end of the telescopic rod 4 is electrically connected to the control system through wires.

[0067] A plurality of counterweights 81 are bolted to the edge of the lower bottom surface of the liquid bucket 71. The counterweights 81 are arranged in a circular array. The function of the counterweights 81 is to facilitate the sinking of the liquid bucket 71 into the water body, and the position of the liquid bucket 71 in the water body can be set by increasing or decreasing the number of counterweights 81.

[0068] In this embodiment, the weight of all the counterweights 81 is greater than the buoyancy generated by the water on the sealing plate 74 during sampling.

[0069] When in use, the sampling device for water conservancy engineering survey is fixedly installed on the land at the edge of the water body where the water sample is to be taken through the ground cone 12, and the first motor 21 is started by the control system. The power output end of the first motor 21 drives the second gear 24 to rotate, and then the first gear 16 rotates, driving the mounting plate 3 and the telescopic rod 4 to rotate. The control system controls the start of the telescopic rod 4 to drive the sampling barrel assembly 7 to extend until the sampling barrel assembly 7 is located above the water sample to be taken;

[0070] The control system starts the second motor 61. The power output end of the second motor 61 drives the rotating roller 62 to rotate, causing the rope 63 to drive the sampling barrel assembly 7 to move downward until the sampling barrel assembly 7 enters the water body. At this time, the sampled water passes through the first filter hole 720 and enters the liquid holding chamber. At this time, the pull ring 79 is pulled, and the water passes through the second filter hole 770 and enters the liquid holding barrel 71. After the sampling is completed, the pull ring 79 is released, and the spring 73 causes the sealing plate 74 to move downward, thereby sealing the water sample in the liquid holding barrel 71.

[0071] The control system controls the second motor 61 to rotate in the opposite direction, and the rope 63 retracts to drive the liquid bucket 71 to move upward. Under the action of the sealing plate 74, the water does not leak. Then the telescopic rod 4 is controlled to retract, and the power output end of the first motor 21 drives the telescopic rod 4 to rotate, driving the liquid bucket 71 to a position above the water sample container. At this time, the pull ring 79 is pulled again to allow the water sample in the liquid bucket 71 to flow into the water sample container through the first filter hole 720 and the second filter hole 770, thereby completing the sampling of the water body.

[0072] By arranging the telescopic rod 4 to be telescopic and rotatable, the sampling range can be expanded, and the degree of automation is high, and sampling is convenient.

[0073] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, replacements and deformations made to the implementation methods are still within the scope of protection of this utility model.
