Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for environmental detection. Background Art

[0002] Environmental testing is to use physical, chemical and biological techniques to conduct qualitative, quantitative and systematic comprehensive analysis of pollutants and their related components in the environment, in order to explore and study the changing laws of environmental quality. Environmental testing mainly includes: atmospheric environment testing, water quality testing, soil environment testing and solid waste testing.

[0003] Among them, when testing water quality, a sampling device is needed. The sampling device can be used to collect water samples in order to analyze various indicators in the water samples, such as dissolved oxygen, pH, heavy metals and organic matter, and then determine whether the water quality is qualified.

[0004] However, the underwater environment is complex, and the water quality environment in different water layers is also different. When workers need to sample deep water quality, since some existing sampling tubes are open structures, when they sink into the water, the sampling tubes are prone to sampling surface water samples, which will affect subsequent water quality testing and increase the error of water quality test results.

[0005] Therefore, there is an urgent need to redesign a new sampling device for environmental testing to solve the above problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It is understandable that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] See also Figures 1 to 4 The utility model discloses a sampling device for environmental detection, which comprises a sampling tube 1, a liquid inlet pipe 2 and a liquid discharge pipe 3.

[0031] The sampling tube 1 is connected with a handle 101, and the handle 101 is used to connect a sampling rope 102. The handle 101 is provided with a sampling rope 102, and the sampling tube 1 can be put into water by using the sampling rope 102, and then the sampling tube 1 can be used to sample water.

[0032] In addition, a mounting member 103 is installed on the top wall of the sampling tube 1. A cavity 104 is provided in the mounting member 103. The cavity 104 is used to accommodate a winding disk 106. The winding disk 106 can be used to wind the linkage rope 208.

[0033] Specifically, a rotating shaft 105 is rotatably disposed in the cavity 104, and a winding disk 106 is disposed on the rotating shaft 105. When the winding disk 106 winds the linkage rope 208, the sliding rod 203 can be realized to slide, so that the blocking block 205 is disengaged from the through hole 202, so that the water sample can enter the sampling tube 1 through the through hole 202.

[0034] In addition, a control unit, a power supply and a motor are also provided in the cavity 104. The output shaft of the motor is connected to the rotating shaft 105. The control unit, the power supply and the motor are electrically connected. The power supply is used to power the motor, and the control unit is used to drive the operation of the motor.

[0035] Preferably, a wireless transmission unit is provided on the control unit so that the staff can remotely control the operation of the motor using a remote controller, which is convenient for operation.

[0036] See also Figures 1 to 4 The liquid inlet tube 2 is connected to the side wall of the sampling tube 1 , and the water sample can enter the sampling tube 1 through the liquid inlet tube 2 .

[0037] Among them, a control mechanism is provided in the liquid inlet pipe 2, which can be used to control the opening and closing of the liquid inlet pipe 2. When the sampling tube 1 is on the surface water surface, if there is no need to collect surface water samples, the liquid inlet pipe 2 can be closed, making it difficult for surface water samples to enter the sampling tube 1.

[0038] In addition, the control mechanism includes a baffle 201, and a plurality of through holes 202 are provided on the baffle 201. The interior of the sampling tube 1 is connected to the outside through the through holes 202. When the blocking block 205 does not block the through holes 202, the water sample can enter the sampling tube 1 through the through holes 202 for collection.

[0039] Specifically, a slide bar 203 is slidably provided on the baffle 201, one end of the slide bar 203 is connected to a blocking plate 204, a plurality of blocking blocks 205 are connected to the blocking plate 204, and the plurality of blocking blocks 205 are respectively inserted into the plurality of through holes 202. The blocking blocks 205 are used to engage with the through holes 202, thereby achieving blocking of the through holes 202. When water sampling is not required, the external water sample will not enter the sampling tube 1 through the through holes 202.

[0040] In addition, the other end of the slide bar 203 is connected to a limit plate 206, and the limit plate 206 is used to limit the elastic sleeve 207. An elastic sleeve 207 is provided on the outside of the slide bar 203, and the elastic sleeve 207 is provided between the limit plate 206 and the baffle 201. When the linkage rope 208 does not apply tension to the blocking plate 204, the blocking block 205 on the blocking plate 204 will be engaged in the through hole 202 under the cooperation of the limit plate 206 and the elastic sleeve 207, thereby achieving the blocking of the through hole 202, so that the water sample is not easy to enter the sampling tube 1.

[0041] See also Figures 1 to 4 The blocking plate 204 is connected with a linkage rope 208, one end of which is wound around the winding disc 106. The blocking plate 204 can be pulled by the linkage rope 208 to move, thereby making the blocking block 205 disengage from the through hole 202, so that the water sample can enter the sampling tube 1 through the through hole 202.

[0042] A sealing ring 209 is disposed outside the linkage rope 208 , and the sealing ring 209 is installed in the mounting member 103 , so that the water sample is not easy to enter the cavity 104 .

[0043] See also Figures 1 to 4 The drain pipe 3 is connected to the side wall of the sampling tube 1 , and is used to discharge the water sample in the sampling tube 1 .

[0044] A plug is installed on the drain pipe 3, and the drain pipe 3 can be blocked by the plug.

[0045] See also Figures 1 to 4 A counterweight block 4 is provided at the bottom of the sampling tube 1, and the counterweight block 4 is used to increase the overall counterweight of the sampling tube 1, so that the sampling tube 1 can sink into the water quickly, so as to improve the sampling efficiency of the water sample.

[0046] A connecting rope 401 is connected between the counterweight block 4 and the sampling tube 1 , and the counterweight block 4 is connected via the connecting rope 401 .

[0047] During specific use, when it is necessary to sample deep water, the sampling tube 1 is put into the water. Under the action of the counterweight 4, the sampling tube 1 can sink quickly, thereby increasing the sinking speed of the sampling tube 1.

[0048] When the sampling tube 1 sinks to a certain depth, the motor is controlled to operate, and the motor drives the winding disk 106 to rotate, and the winding disk 106 will wind the linkage rope 208. The linkage rope 208 will pull the blocking plate 204, thereby causing the blocking block 205 on the blocking plate 204 to break away from the engagement with the through hole 202. At this time, the water sample enters the sampling tube 1 through the through hole 202 and is collected.

[0049] When the sampling tube 1 has finished sampling, the motor is disconnected, and the linkage rope 208 no longer generates tension on the blocking plate 204. The blocking block 205 will be re-engaged in the through hole 202 under the action of the limit plate 206 and the elastic sleeve 207, so as to achieve the blocking of the through hole 202, so that the external water sample will no longer enter the sampling tube 1. The sampling tube 1 can be pulled up by the sampling rope 102, and the surface water sample will not be collected during the rising process of the sampling tube 1, thereby ensuring the overall collection effect of the water sample.

[0050] When it is necessary to discharge the water sample in the sampling tube 1, remove the plug on the drainage pipe 3, and the water sample in the sampling tube 1 is discharged through the drainage pipe 3. The staff then analyzes the collected water sample to know the water quality of the collected water layer.

[0051] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
