Description

Technical Field

[0001] The present invention belongs to the field of hydrological survey, and particularly relates to a water resource detection sampling device and method. Background Art

[0002] With the development of the times, water use safety has become a top priority. Therefore, it is necessary to regularly detect the water quality. When detecting water, it is necessary to first take out the water from places such as lakes and ditches using a water body sampling device. However, most of the existing water body sampling devices have the following problems:

[0003] During the use of existing water body sampling devices, it is mostly inconvenient to simultaneously collect water at different depths, and the accuracy of detection cannot be ensured. Moreover, during the sampling process, it is necessary to manually operate to open the collection bottle on the water surface. Therefore, a very long operating rod is required according to the depth, which is very troublesome. In view of the above problems, it is urgent to innovate and design on the basis of the original water body sampling device. Summary of the Invention

[0004] In order to solve the problems existing in the above-mentioned prior art, a water resource detection sampling device and method are provided.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] The present invention provides a water resource detection sampling device, including a device main body. A plurality of collection bottles are arranged inside the device main body. One end of each collection bottle is provided with a bottle mouth, and a bottle stopper is arranged inside the bottle mouth. The bottle stopper is fixedly connected with a moving block. One end of the moving block is connected with a T-shaped block. One end of the T-shaped block is clamped with an automatic release clamp. A chute is provided on the device main body, and the moving block is slidably connected to the chute.

[0007] Preferably, the device main body is connected with a piston cylinder. A piston is slidably connected to the piston cylinder. The piston is connected to the piston cylinder through a spring. The piston is fixedly connected with a stop rod, and the stop rod contacts the moving block.

[0008] Preferably, a second tension spring is connected below the moving block, and the second tension spring is connected to the device main body.

[0009] Preferably, the automatic release clamp is composed of two clamp handles. A torsion spring is connected between the two clamp handles. One end of the two clamp handles is a clamp mouth, and the other end is a clamp tail. The clamp mouth is clamped with the T-shaped block.

[0010] Preferably, a release opening adapted to the clamp tail is provided inside the device main body.

[0011] Preferably, a sliding block is slidably connected to the sliding groove, the sliding block is fixedly connected to a rotating shaft, and both clamping handles are rotatably connected to the automatic release clamp through the rotating shaft.

[0012] Preferably, the automatic release clamp is connected to a first tension spring, and the other end of the first tension spring is connected to the device main body.

[0013] Preferably, the elastic force of the first tension spring is greater than that of the second tension spring. In the initial state, the first tension spring is in a stretched state.

[0014] Preferably, the contact surface between the clamping jaws and the T-shaped block is a horizontal plane.

[0015] The present invention also provides a usage method of a water resource detection sampling device. Using the above-mentioned water resource detection sampling device, it includes the following steps:

[0016] S1: The operator pulls the pull rope to place the device into the water to be detected. As the depth increases, the water pressure compresses the piston to move, and the piston drives the shift lever to move;

[0017] S2: The shift lever disengages from the moving block, the first tension spring pulls the automatic release clamp to move, the automatic release clamp drives the T-shaped block to move, the T-shaped block drives the moving block to move, and the moving block drives the bottle stopper for blocking the collection bottle to move. During this process, the second tension spring is stretched;

[0018] S3: The bottle stopper opens the collection bottle, and the water sample flows into the collection bottle. The automatic release clamp continues to move to the right. When the clamp tail touches the release port, the two clamping handles rotate around the rotating shaft, the clamp tail swings inward, and the clamping jaws swing outward. The clamping jaws release the T-shaped block. During this process, the torsion spring deforms;

[0019] S4: The moving block moves to the left under the pull of the second tension spring. The moving block drives the bottle stopper to move to the left. The bottle stopper closes the collection bottle. The device continues to move downward, and can open the corresponding collection bottle according to the pressure at different depths and automatically cover the bottle mouth. The shift lever opens and closes the collection bottle in the same way.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. In the present invention, the pressure at different depths of the water body is utilized to press the piston downward. At this time, the piston drives the shift lever to move, and the shift lever releases the restriction on the moving block. The first tension spring pulls the automatic release clamp to move. The automatic release clamp pulls the moving block to the left, and the moving block drives the stopper of the blocking collection bottle to move. The stopper opens the collection bottle, and the water sample flows into the collection bottle. The automatic release clamp continues to move to the right. When the tail of the clamp touches the release port, under the action of the torsion spring, the tail of the clamp swings inward, and the jaws of the clamp swing outward. The jaws of the clamp release the T-shaped block, and the moving block moves to the left under the pull of the second tension spring. The moving block drives the stopper to move to the left, and the stopper closes the collection bottle. This device can open the corresponding collection bottle according to the pressure at different depths and automatically cover the bottle mouth, and can simply and conveniently collect water samples at different depths, reducing the operation difficulty of the operator to a certain extent.

Detailed Description of the Embodiment

[0027] The following describes in detail the embodiments of the present invention. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0028] As Figure 1-2A water resource detection and sampling device is shown, including a device main body 1. Inside the device main body 1, there are several collection bottles 2. One end of the collection bottle 2 is provided with a bottle mouth, and a bottle stopper 5 is arranged inside the bottle mouth. The bottle stopper 5 is fixedly connected to a moving block 6. One end of the moving block 6 is connected to a T-shaped block 15. There is a gap between the vertical part of the T-shaped block 15 and the moving block 6. One end of the T-shaped block 15 is clamped with an automatic release clamp 9. The device main body 1 is provided with a chute 14, and the chute 14 is slidably connected to the moving block 6. The automatic release clamp 9 is composed of two pliers handles, and a torsion spring is connected between the two pliers handles. The pliers mouth 16 of the automatic release clamp 9 adopts an L-shaped structure, and the pliers mouth 16 part is clamped at the gap part of the T-shaped block 15. The device main body 1 is provided with a chute 14, and the chute 14 is slidably matched with the moving block 6. The chutes 14 are arranged oppositely, and several collection bottles 2 are arranged vertically. Such a setting can better extract water sources at different depths.

[0029] The device main body 1 is connected with a piston cylinder 19. The piston cylinder 19 is arranged inside the device main body 1. The piston 12 is connected to the piston cylinder 19 through a spring 13. A closed setting is arranged between the piston 12 and the piston cylinder 19, and water flow will not flow into the bottom of the piston 12. The piston 12 is fixedly connected to a stop rod 7. The stop rod 7 freely passes through the device main body 1 and is in contact with the moving block 6. Driven by the spring 13, the stop rod 7 can slide up and down inside the device main body 1. The stop rod 7 is used to lock or release the moving block 6.

[0030] A first spring seat is connected below the moving block 6. The first spring seat passes through the chute 14 and is slidably connected to the chute 14. One side of the first spring seat is connected with a second tension spring 18. The other end of the second tension spring 18 is connected with a second spring seat. The second spring seat is connected to the device main body 1. When the moving block 6 is pulled by the first tension spring 8, the pulling force of the first tension spring 8 is greater than that of the second tension spring 18. When the moving block 6 is released, the second tension spring 18 pulls the moving block 6 back.

[0031] The automatic release clamp 9 is composed of two pliers handles, and a torsion spring is connected between the two pliers handles. One end of the two pliers handles is the pliers mouth 16, and the other end of the two pliers handles is the pliers tail 17 and is inclined. The pliers mouth 16 is clamped with the T-shaped block 15. The pliers tail 17 of the automatic release clamp 9 can cooperate with the release port 10. The release port 10 is composed of two inclined surfaces. The distance between the rightmost ends of the pliers tail 17 is less than the distance between the leftmost ends of the release port 10. When the first tension spring 8 pulls the release clamp 9, the automatic release clamp 9 pulls the moving block 6 to move. When the pliers tail 17 is engaged with the release port 10, the pliers mouth 16 releases the T-shaped block 15. At this time, the second tension spring 18 will pull the moving block 6 back.

[0032] The sliding block 11 is slidably connected to the sliding groove 14. The sliding block 11 is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the automatic release clamp 9. When the sliding block 11 moves in the sliding groove 14, it will drive the automatic release clamp 9 to move. At the same time, the sliding block 11 will play a guiding role for the automatic release clamp 9 to ensure that the automatic release clamp 9 moves in a straight line.

[0033] A connecting block is arranged inside the moving block 6. One end of the connecting block is connected to a bottle stopper 5, and the bottle stopper 5 plugs the bottle mouth of the collection bottle 2. The collection bottle 2 is arranged inside the device main body 1. When the bottle stopper 5 is pulled open by the moving block 6, the water source to be collected enters the collection bottle 2 under the action of water pressure.

[0034] The pulling force of the first tension spring 8 is greater than that of the second tension spring 18. In the initial state, the first tension spring 8 is in a stretched state. When the second tension spring 18 is connected to the moving block 6, the first tension spring 8 can pull the moving block 6 towards itself.

[0035] A release port 10 adapted to the clamp tail 17 is opened inside the device main body 1. The release port 10 is set in a V shape. The shape of the release port 10 is used to cooperate with the clamp tail 17. The clamp tail 17 is smaller than the release port 10. When the clamp tail 17 is engaged in the release port 10, the clamp jaws 16 release the limit on the T-shaped block 15, and the second tension spring 18 pulls the moving block 6 back, and the bottle stopper 5 connected to the moving block 6 plugs the bottle mouth of the collection bottle 2.

[0036] The contact surface between the clamp jaws 16 and the T-shaped block 15 is a horizontal plane. The horizontally arranged surface increases the friction between the clamp jaws 16 and the T-shaped block 15, making the clamping of the clamp jaws 16 closer.

[0037] A usage method of a water resource detection and sampling device, using a water resource detection and sampling device described in this embodiment, includes the following steps:

[0038] S1: The operator pulls the pull rope 4 to put this device into the water to be detected. The pull rope 4 is connected to the pull ring 3. As the depth increases, the water pressure compresses the piston 12 to move, and the piston 12 drives the shift lever 7 to move;

[0039] S2: The shift lever 7 disengages from the moving block 6. The first tension spring 8 pulls the automatic release clamp 9 to move. The automatic release clamp 9 drives the T-shaped block 15 to move. The T-shaped block 15 drives the moving block 6 to move. The moving block 6 drives the bottle stopper 5 used to block the collection bottle 2 to move. During this process, the second tension spring 18 is stretched;

[0040] S3: The bottle stopper 5 opens the collection bottle 2, and the water sample flows into the collection bottle 2. The automatic release clamp 9 continues to move to the right. When the clamp tail 17 touches the release port 10, the two clamp handles rotate around the rotating shaft, the clamp tail 17 swings inward, the clamp jaws 16 swing outward, and the clamp jaws 16 release the T-shaped block 15. During this process, the torsion spring deforms;

[0041] S4: The moving block 6 moves leftward under the pull of the second tension spring 18. The moving block 6 drives the stopper 5 to move leftward, and the stopper 5 closes the collection bottle 2. The device continues to move downward, can open the corresponding collection bottle 2 according to the pressure at different depths and automatically cover the bottle mouth. The stop lever 7 opens and closes the collection bottle 2 in the same way.

[0042] It should be noted that when the stop lever 7 disengages from the moving block 6, since the pulling force of the first tension spring 8 is greater than that of the second tension spring 18, the first tension spring 8 will pull the automatic release clamp 9 to move. The automatic release clamp 9 drives the T-shaped block 15 to move. The T-shaped block 15 drives the moving block 6 to move. The moving block 6 drives the stopper 5 blocking the collection bottle 2 to move. During this process, the second tension spring 18 is in a stretched state, and the collection bottle 2 is opened. The water to be sampled will enter the collection bottle 2 under the pressure of the water.

[0043] In addition, when the stopper 5 opens the collection bottle 2 and the water sample flows into the collection bottle 2, the first tension spring 8 continues to pull the automatic release clamp 9 to move rightward. When the clamp tail 17 contacts the release port 10, the clamp tail 17 engages with the release port 10. The two clamp handles rotate around the rotating shaft. The clamp tail 17 swings inward, and the clamp mouth 16 swings outward. The clamp mouth 16 releases the T-shaped block 15. During this process, the torsion spring deforms. The clamp mouth 16 releases the T-shaped block 15, and the moving block 6 connected to the T-shaped block 15 will move leftward to complete the blocking of the collection bottle 2.

[0044] In addition, after the automatic release clamp 9 releases the T-shaped block 15, the moving block 6 connected to the T-shaped block 15 moves leftward under the pull of the second tension spring 18. At this time, the stopper 5 also moves leftward under the drive of the moving block 6, and the stopper 5 closes the collection bottle 2. The collection of the first layer of water source is completed. When it is necessary to collect water samples at a deeper position, the device continues to move downward. The stop lever 7 opens and closes the collection bottle 2 in the same way. When the collection is completed, the operator pulls the pull rope 4 to lift the device.

[0045] The springs involved in this solution are all mature products on the market and can be purchased according to the design requirements.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
