Description

Technical Field

[0001] The utility model relates to the technical field of water sample collection, and more specifically, it relates to an extendable probe for water sample collection. Background Technique

[0002] Hydrogeology, environmental geology and engineering geology are branches of geology. Hydrogeology is the science that studies groundwater, mainly focusing on the distribution and formation laws of groundwater, the physical properties and chemical compositions of groundwater, the rational utilization of groundwater resources, the adverse impacts of groundwater on engineering construction and mine exploitation and their prevention and control. With the development of science and the needs of production and construction, hydrogeology is further divided into branch disciplines such as regional hydrogeology, groundwater dynamics, hydrogeochemistry, water supply hydrogeology, ore deposit hydrogeology, and hydrogeology for soil improvement. When sampling water quality, a water sample collection probe is usually required. When using the existing extendable probe for sampling, it is necessary to send the sampling probe into the water. After collecting the sample, the sample is then stored in a sampling test tube. The sampling process is relatively cumbersome. To solve the above problems, we have developed the following device. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide an extendable probe for water sample collection, which has the characteristic of a simple sampling process.

[0005] (2) Technical Solution

[0006] To achieve the above object, the utility model provides an extendable probe for water sample collection, which includes a hollow rod and a movable rod. The movable rod is inserted into the hollow rod. A movable plate is fixedly connected to the lower end of the hollow rod, and a collection probe is fixedly connected to the surface of the movable plate. An installation frame is fixedly connected to the surface of the hollow rod, and a U-shaped seat is fixedly connected to the surface of the installation frame. A hollow rotating shaft is fixedly connected to the surface of the U-shaped seat through a bearing. A pipeline connector is inserted through the surface of the hollow rotating shaft, and a wire reel is fixedly connected to the surface of the hollow rotating shaft. A soft conduit is wound around the surface of the wire reel. One end of the soft conduit is inserted into the pipeline connector, and the other end of the soft conduit is fixedly connected to the inner wall of the output port of the collection probe. A housing is fixedly connected to the surface of the installation frame. A first rotating shaft is fixedly connected to the inner wall of the housing through a bearing. A clockwork spring is arranged inside the housing. One end of the clockwork spring is fixedly connected to the inner wall of the housing, and the other end of the clockwork spring is fixedly connected to the surface of the first rotating shaft. One end of the hollow rotating shaft is fixedly connected to one end of the first rotating shaft. A rotary joint is fixedly connected to the surface of the U-shaped seat. One rotatable end of the hollow rotating shaft is inserted into the hollow rotating shaft. The output end of the rotary joint is fixedly connected to a first conduit. A micro water pump is fixedly connected to the surface of the installation frame. The other end of the first conduit is fixedly connected to the input end of the micro water pump. A support block is fixedly connected to the surface of the installation frame. A second conduit is inserted through the surface of the support block. One end of the second conduit is fixedly connected to the output end of the micro water pump, and the other end of the second conduit is sleeved with a rubber plug. Vent holes are formed on the surface of the rubber plug.

[0007] When using an extendable probe for water sample collection of this technical solution, by setting a micro water pump, a rubber plug and vent holes, during sampling, people sleeve a sampling test tube on the surface of the rubber plug and insert the probe into the water to an appropriate depth. Then people control the micro water pump to operate through a control switch, so that the water sample at an appropriate depth sequentially enters the sampling test tube through the collection probe, the soft conduit, the pipeline connector, the hollow rotating shaft, the rotary joint, the first conduit, the micro water pump, the second conduit and the rubber plug. The water sample squeezes the air in the sampling test tube, so that the air is discharged through the vent holes, preventing the internal pressure of the sampling test tube from increasing and detaching from the rubber plug. Until enough samples are collected in the sampling test tube, then stop the operation of the micro water pump and the sampling test tube can be removed. This process does not require removing the sampling probe out of the water surface, and the sampling process is relatively simple.

[0008] Further, a support plate is fixedly connected to the inner wall of the hollow rod near the top position. A second rotating shaft is fixedly connected to the surface of the support plate through a bearing.

The limiting block is fixedly connected to the surface of the movable rod.

[0009] Further, one end of the hollow rotating shaft close to the first rotating shaft is not communicated.

[0010] Further, the rubber plug has a frustum shape in appearance.

[0012] Further, a storage battery is fixedly connected to the surface of the mounting bracket, a control switch is fixedly connected to the surface of the hollow rod, and the control switch is electrically connected to the storage battery and the micro motor through wires respectively.

[0013] Further, a pipeline bracket is sleeved on the surface of the flexible conduit, and the pipeline bracket is fixedly connected to the surface of the hollow rod near the bottom.

[0015] In summary, the present utility model has the following beneficial effects:

[0016] 1. For the extendable probe for water sample collection, by setting the micro water pump, the rubber plug and the ventilation holes, when sampling, people sleeved the sampling test tube on the surface of the rubber plug, inserted the probe into the water to an appropriate depth, and then people controlled the operation of the micro water pump through the control switch, so that the water sample at an appropriate depth entered the sampling test tube through the collection probe, the flexible conduit, the pipeline connector, the hollow rotating shaft, the rotary joint, the first conduit, the micro water pump, the second conduit and the rubber plug in sequence. The water sample squeezed the air in the sampling test tube, so that the air was discharged through the ventilation holes, preventing the internal pressure of the sampling test tube from increasing and detaching from the rubber plug. Until enough samples were collected in the sampling test tube, and then stop the operation of the micro water pump, the sampling test tube can be removed. This process does not require removing the sampling probe out of the water surface, and the sampling process is relatively simple;

[0026] Embodiment:

[0027] The following further describes the present utility model in detail with reference to the attached Figures 1-4 drawings.

[0028] Please refer to Figures 1-4, the present utility model provides a technical solution: an extendable probe for water sample collection, which includes a hollow rod 1 and a movable rod 2. The movable rod 2 is inserted into the hollow rod 1. A movable plate 3 is fixedly connected to the lower end of the hollow rod 1. A collection probe 4 is fixedly connected to the surface of the movable plate 3. An installation frame 5 is fixedly connected to the surface of the hollow rod 1. A U-shaped seat 6 is fixedly connected to the surface of the installation frame 5. A hollow rotating shaft 7 is fixedly connected to the surface of the U-shaped seat 6 through a bearing. A pipeline connector 8 is inserted through the surface of the hollow rotating shaft 7. A wire reel 9 is fixedly connected to the surface of the hollow rotating shaft 7. A flexible conduit 10 is wound around the surface of the wire reel 9. One end of the flexible conduit 10 is inserted into the pipeline connector 8. The other end of the flexible conduit 10 is fixedly connected to the inner wall of the output port of the collection probe 4. A housing 11 is fixedly connected to the surface of the installation frame 5. A first rotating shaft 12 is fixedly connected to the inner wall of the housing 11 through a bearing. A clockwork spring 13 is arranged inside the housing 11. One end of the clockwork spring 13 is fixedly connected to the inner wall of the housing 11. The other end of the clockwork spring 13 is fixedly connected to the surface of the first rotating shaft 12. One end of the hollow rotating shaft 7 is fixedly connected to one end of the first rotating shaft 12. A rotary joint 14 is fixedly connected to the surface of the U-shaped seat 6. The rotatable end of the hollow rotating shaft 7 is inserted into the hollow rotating shaft 7. The output end of the rotary joint 14 is fixedly connected to a first conduit 15. A micro water pump 16 is fixedly connected to the surface of the installation frame 5. The other end of the first conduit 15 is fixedly connected to the input end of the micro water pump 16. A support block 17 is fixedly connected to the surface of the installation frame 5. A second conduit 18 is inserted through the surface of the support block 17.

Air holes 20 are opened on the surface of the rubber plug 19.

[0029] By adopting the above technical solution, for the extendable probe for water sample collection, by setting the micro water pump 16, the rubber plug 19 and the air holes 20, during sampling, people sleeve the sampling test tube on the surface of the rubber plug 19, insert the probe into the water to an appropriate depth, and then people control the micro water pump 16 to operate through the control switch 29, so that the water sample at an appropriate depth sequentially passes through the collection probe 4, the flexible conduit 10, the pipeline connector 8, the hollow rotating shaft 7, the rotary joint 14, the first conduit 15, the micro water pump 16, the second conduit 18 and the rubber plug 19 and enters the sampling test tube. The water sample squeezes the air in the sampling test tube, so that the air is discharged through the air holes 20, preventing the internal pressure of the sampling test tube from increasing and detaching from the rubber plug 19. Until enough samples are collected in the sampling test tube, then stop the operation of the micro water pump 16 and the sampling test tube can be removed. This process does not require removing the sampling probe out of the water surface, and the sampling process is relatively simple.

[0030] Specifically, a support plate 21 is fixedly connected to the inner wall of the hollow rod 1 near the top. A second rotating shaft 22 is fixedly connected to the surface of the support plate 21 through a bearing. A crank 23 is fixedly connected to the upper end of the second rotating shaft 22. A threaded column 24 is fixedly connected to the lower end of the second rotating shaft 22. A threaded tube 25 is disposed through the movable rod 2. The threaded tube 25 is threadedly connected to the surface of the threaded column 24. A limiting groove 26 is formed in the inner wall of the movable rod 2. A limiting block 27 is slidably connected in the limiting groove 26. The limiting block 27 is fixedly connected to the surface of the movable rod 2.

[0031] By adopting the above technical solution, for the extendable probe for water sample collection, by providing the crank 23, the threaded column 24 and the threaded tube 25, when collecting water samples at a relatively deep depth, people can rotate the crank 23, thereby driving the second rotating shaft 22 and the threaded column 24 to rotate. Under the mutual cooperation of the threaded column 24 and the threaded tube 25, the threaded tube 25 moves and drives the movable rod 2 to withdraw from the hollow rod 1, thereby driving the movable plate 3 and the collection probe 4 away from the hollow rod 1, facilitating people to collect water samples at a relatively deep depth.

[0032] Specifically, one end of the hollow rotating shaft 7 close to the first rotating shaft 12 is not communicated.

[0033] Specifically, the rubber plug 19 has a frustum shape.

[0034] Specifically, there are two groups of the limiting grooves 26 and the limiting blocks 27, and they are symmetrically arranged on the inner wall of the hollow rod 1.

[0035] Specifically, a storage battery 28 is fixedly connected to the surface of the mounting bracket 5. A control switch 29 is fixedly connected to the surface of the hollow rod 1. The control switch 29 is electrically connected to the storage battery 28 and the micro motor through wires respectively.

[0036] Specifically, a pipeline support 30 is sleeved on the surface of the flexible conduit 10. The pipeline support 30 is fixedly connected to the surface of the hollow rod 1 near the bottom.

[0037] The working principle of the present utility model is as follows: When in use, people consider whether to extend the probe rod according to the depth of the water sample to be collected. When collecting water samples at a deeper depth, people can rotate the crank 23, which drives the second rotating shaft 22 and the threaded column 24 to rotate. Under the mutual cooperation of the threaded column 24 and the threaded tube 25, the threaded tube 25 moves and drives the movable rod 2 to withdraw from the hollow rod 1, thereby driving the movable plate 3 and the sampling probe 4 away from the hollow rod 1. During the process of extending the probe rod, due to the presence of the wire reel 9 and the spring 13, the flexible conduit 10 can be automatically retracted and extended to adapt to the overall length change of the extended probe rod. Then, people sleeved the sampling test tube on the surface of the rubber stopper 19 and inserted the probe into the water at an appropriate depth. Then, people control the operation of the micro water pump 16 through the control switch 29, so that the water sample at an appropriate depth successively passes through the sampling probe 4, the flexible conduit 10, the pipeline connector 8, the hollow rotating shaft 7, the rotary joint 14, the first conduit 15, the micro water pump 16, the second conduit 18 and the rubber stopper 19 and enters the sampling test tube. The water sample squeezes the air in the sampling test tube, so that the air is discharged through the air holes 20, preventing the internal pressure of the sampling test tube from increasing and detaching from the rubber stopper 19. Until enough samples are collected in the sampling test tube, then stop the operation of the micro water pump 16 and the sampling test tube can be removed.

[0038] This specific embodiment is only an explanation of the present utility model, and it is not a limitation to the present utility model. Those skilled in the art can make modifications without creative contributions to this embodiment according to needs after reading this specification, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
