Abstract
Description
Technical Field
[0001] This application relates to the technical field of environmental detection sampling, and particularly to a shallow water sampling device that can display flow rate in real time. Background Art
[0002] In order to obtain the relevant basic data of water body pollution, collecting water samples from polluted water bodies is a key measure. The commonly used water body sampling equipment at present is towed by a rope and cannot take samples according to the preset sampling water depth, which makes the water bodies at different depths mixed, increasing the uncertainty of the samples and bringing trouble to subsequent data processing. Moreover, there is no flow control device, resulting in inaccurate collection of water body samples.
[0003] Generally, during shallow water sampling, it is impossible to reach the preset sampling depth for accurate sampling, or the sampling tube and the sampling device are integrally formed, and it is inconvenient to adjust the length of the sampling tube according to different depths. Utility Model Content
[0004] In order to improve the problem of inconvenient collection of water samples at preset depths, this application provides a shallow water sampling device that can display flow rate in real time.
[0005] The shallow water sampling device that can display flow rate in real time provided by this application adopts the following technical solutions:
[0006] A shallow water sampling device that can display flow rate in real time includes a sampler main body, a gas flow meter, an airbag pump, and a sampling tube. The airbag pump is communicated with the sampler main body. The gas flow meter is arranged at the output end of the sampler main body, and the sampling tube is installed at the input end of the sampler main body. Among them, the sampling tube and the sampler main body are connected by a locking member, and the locking member is used to lock the sampler main body to connect sampling tubes with different extended lengths.
[0007] By adopting the above technical solutions, the sampler main body is inflated or deflated by the airbag pump to collect samples from water bodies at different depths. A two-way gas flow meter is connected to the outside of the sampler main body to display the water body flow rate data during collection. When collecting water samples at shallow water areas, the turbidity of the water bodies in different depth environments is different. The length of the sampling tube located in the water can be adjusted through the locking member at the input end of the sampler main body to achieve sampling at different preset sampling water depths.
[0008] Optionally, the locking member includes a first spring, a clamping ring, and a pull rod. A groove is opened at the input end of the sampler main body. The ends of the first spring located in the groove are respectively fixed to the clamping ring and the inner side wall of the groove. The pull rod passes through the sampler main body and is fixed to the clamping ring, and the pull rod is slidably matched with the sampler main body.
[0009] By adopting the above technical solution, the sampler pulls the pull rods on both sides of the sampler body in the direction away from each other. The first spring located between the clamping ring and the inner side wall of the groove is compressed, and the two clamping rings for clamping the outer wall of the sampling tube move away from each other. The sampling tube is extended or contracted according to different depths of the water body. When the pull rods on both sides are released, the two clamping rings clamp the sampling tube tightly.
[0010] Optionally, scale lines are provided on the sampling tube along its own length direction.
[0011] By adopting the above technical solution, the scale lines facilitate more accurate collection of the water level depth during sampling.
[0012] Optionally, handles are symmetrically fixed to the sampler body along its own axis, and rings are installed at the ends of the handles.
[0013] By adopting the above technical solution, the handles on both sides of the sampler body facilitate manual holding by the sampler, and are convenient for carrying. There is a ring at the tip of each handle, which is convenient for hanging and placing after use.
[0014] Optionally, the locking member includes a rotating shaft, a clamping ring, a second spring and a protrusion. An activity cavity for the rotating shaft to rotate is provided inside the sampler body. One end of the rotating shaft is fixed to the clamping ring, and the other end of the rotating shaft is fixed to the protrusion. Both ends of the second spring are fixed to the clamping ring and the inner side wall of the activity cavity respectively; when the clamping ring fits against the outer wall of the sampling tube, the protrusion penetrates and is exposed on the sampler body.
[0015] By adopting the above technical solution, the sampling tube is clamped by the two clamping rings on both sides. The elastic action of the second spring causes the clamping ring at one end of the rotating shaft to tend to press tightly against the outer wall of the sampling tube. The other end of the rotating shaft is connected to the protrusion that penetrates out of the sampler body. After the sampler presses the protrusion, the clamping rings on both sides of the sampling tube rotate along the rotating part of the rotating shaft, and the second spring is compressed. The sampling tube moves inside the input end of the sampler body. The sampling tube is placed at the depth to be collected. When the pressing on the protrusion is released, the clamping ring realizes the pressing action on the outer wall of the sampling tube.
[0016] Optionally, the airbag pump includes an airbag, steel balls and a control pump. The input end of the airbag is communicated with the input end of the sampler body, and the output end of the airbag is communicated with the output end of the sampler body. An air injection hole is also provided on the sampler body. The control pump is communicated with the air injection hole through a pipeline. The steel balls are located at the input end and the output end of the airbag.
[0017] By adopting the above technical solution, the steel balls are respectively located at the input end and the output end inside the airbag, playing a plugging role for the ports. The control pump pumps air in or out of the sampler main body in the air injection hole, so as to realize the flow of the collected water through the airbag, ensure the low speed of the collected water sample, reduce the contact between the collected water sample and air, and ensure the accuracy of the result.
[0018] Optionally, an anti-slip sleeve is sleeved on the grip.
[0019] By adopting the above technical solution, it is used to increase friction, improve the anti-slip effect, and can reduce the wear of the grip during use.
[0020] Optionally, the diameter of the steel ball is larger than the diameter of the input end / output end of the airbag.
[0021] By adopting the above technical solution, it is convenient for the steel ball to play a plugging role for the port of the airbag.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When sampling shallow water, the airbag pump compresses the air inside the airbag by compressed air, so as to realize the extraction or discharge of liquid. The input end of the sampler main body is connected to the sampling pipe and fastened by a locking member, which helps to accurately sample at the preset sampling depth;
[0024] 2. Since the sampling pipe can be manually adjusted according to the locking member to be located in water bodies at different depths, the sampler main body is externally connected to a two-way gas flowmeter to display the flow data in real time;
[0025] 3. A sampling pipe is extended and locked at the input end of the sampler main body, which is convenient for observing the degree of water body mixing during sampling, reducing uncertain substances in the sample, and improving the accuracy of the collected water body sample.

Detailed implementation manners
[0033] The following further elaborates on the present application in conjunction with the Figures 1-5 accompanying drawings.
[0034] Embodiment 1
[0035] An embodiment of the present application discloses a shallow water sampling device for real-time display of flow rate.
[0036] Referring to Figure 1 , it includes a sampler body 1, a gas flowmeter 2, an airbag pump, and a sampling tube 4. The airbag pump is communicated with the sampler body 1. The gas flowmeter 2 is arranged at the output end of the sampler body 1, and the sampling tube 4 is installed at the input end of the sampler body 1. Among them, the sampling tube 4 and the sampler body 1 are connected by a locking member 5. The locking member 5 is used to lock the sampler body 1 to connect sampling tubes 4 with different extension lengths. A two-way gas flowmeter 2 is connected to the outside of the sampler body 1, which is convenient for displaying flow rate data when collecting water bodies. The sampling tube 4 is sampled at different preset depths by relying on the locking member 5, improving the accuracy of sampling.
[0037] See Figure 4As shown, the locking member 5 includes a first spring 501, a clamping ring 502 and a pull rod 503. The input end of the sampler main body 1 is provided with a groove. The end parts of the first spring 501 located in the groove are respectively fixed to the clamping ring 502 and the inner side wall of the groove. The pull rod 503 passes through the sampler main body 1 and is fixed to the clamping ring 502. The pull rod 503 is slidably matched with the sampler main body 1. The groove is in a circular ring 8 shape, and the clamping ring 502 is in an arc shape. Three first springs 501 are fixed on each side of the clamping ring 502. The clamping ring 502 located in the groove is in contact with the top and bottom of the groove respectively. The caliber of the splicing of the two clamping rings 502 is smaller than the outer diameter of the sampling tube 4. Manually pull the pull rods 503 on both sides of the sampler main body 1. The first spring 501 located between the groove and the clamping ring 502 is compressed. The pull rod 503 drives the two clamping rings 502 to move away from each other, so as to facilitate the adjustment of the telescopic length of the sampling tube 4 according to different water depths. After the adjustment is completed, release the pull rod 503 by hand, and the clamping plates approach each other and press against the outer wall of the sampling tube 4.
[0038] See Figure 4 As shown, the sampling tube 4 is provided with scale lines 6 along its own length direction. According to the scale lines 6 on the sampling tube 4, it is convenient for the sampling personnel to observe and record the depth of the sampled water body.
[0039] See Figure 2 and Figure 3 As shown, the sampler main body 1 is symmetrically fixed with a handle 7 along its own axis, which is convenient for the sampling personnel to carry. A circular ring 8 is installed at the end of the handle 7, and an anti-slip sleeve 9 is sleeved on the handle 7. The handle 7 perpendicular to the axis of the sampler main body 1 is convenient for the sampling personnel to keep in the same parallel line with the horizontal when collecting water. The anti-slip sleeve 9 on the handle 7 increases the friction during daily water sampling and reduces the occurrence of slipping.
[0040] See Figure 2 and Figure 3 As shown, the airbag pump includes an airbag 3, steel balls 31, a control pump 32 and a hydraulic cylinder piston at the input port inside the sampler main body 1. The input end of the airbag 3 is communicated with the input end of the sampler main body 1, and the output end of the airbag 3 is communicated with the output end of the sampler main body 1. The sampler main body 1 is also provided with an air injection hole 33. The control pump 32 is communicated with the air injection hole 33 through a pipeline. The steel balls 31 are located at the input end and the output end of the airbag 3, and the diameter of the steel balls 31 is larger than the caliber of the input end / output end of the airbag 3.
[0041] The implementation principle of the embodiment of this application is to compress the air in the airbag 3 through compressed air to achieve the extraction or discharge of liquid. When the control pump 32 is started, the air is compressed to a certain pressure and then transported to the airbag 3. The steel ball 31 in the airbag 3 at the input end of the sampler is pushed open by the water body, and the water slowly flows into the airbag 3 through the water inlet, realizing liquid extraction; as the airbag 3 expands, the air injection hole 33 discharges air outward. When the airbag 3 expands to the maximum extent and the airflow outward from the air injection hole 33 stops, gas is introduced into the sampler main body 1. As the internal gas increases, the outside of the airbag 3 is pressured by the gas and contracts, and the steel ball 31 in the airbag 3 at the output end is pushed open by the water flow, realizing liquid discharge;
[0042] According to the different depths of the water body to be sampled, manually pull the pull rod 503 to make the clamping rings 502 on the outer wall of the sampling tube 4 move away from each other, which is convenient for adjusting the length of the sampling tube 4 extending outside the sampler main body, and helps the sampling tube 4 reach the preset sampling depth for accurate sampling; extend the sampling tube 4 with scale lines 6, which is convenient for observing the water body and reducing uncertain substances in the sampling, and improving the accuracy of the collected water body samples.
[0043] Embodiment 2
[0044] See Figure 5 As shown, compared with Embodiment 1, the locking member 5 in this embodiment includes a rotating shaft 510, a clamping ring 502, a second spring 511 and a protrusion 512. An activity cavity for the rotating shaft 510 to rotate is provided inside the sampler main body 1. One end of the rotating shaft 510 is fixed to the clamping ring 502, and the other end of the rotating shaft 510 is fixed to the protrusion 512. Both ends of the second spring 511 are fixed to the clamping ring 502 and the inner side wall of the activity cavity respectively; when the clamping ring 502 fits with the outer wall of the sampling tube 4, the protrusion 512 penetrates and is exposed on the sampler main body 1. A space for the rotating shaft 510 to rotate is provided on the sampler main body 1 and is communicated with the activity cavity. When the protrusions 512 on both sides of the sampler main body 1 are pressed by hand, the protrusions 512 drive the rotating shaft 510 to rotate around its rotating part with the sampler main body 1. The rotating shaft 510 is fixed at one end of the clamping ring 502 to compress the second spring 511, and the clamping rings 502 on both sides move away from each other, realizing the loosening of the outer wall of the sampling tube 4. According to the depth required for sampling of the sampling tube 4, the extension length is adjusted. When the hand is released, the second spring 511 drives the rotating shaft 510 and the clamping ring 502 to reset and move back, realizing the tightening effect on the outer wall of the sampling tube 4. Compared with Embodiment 1, it is more convenient for simple operation in adjusting the locking length between the sampler main body 1 and the sampling tube 4.
