Description

Technical Field

[0001] The utility model relates to a sampling device, in particular to a water quality sampling device for environmental monitoring. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the environmental quality status. By monitoring and measuring indicators that reflect environmental quality, the environmental pollution status and environmental quality are determined. Environmental monitoring includes water quality testing, air pollutant testing, solid waste testing, etc. Among them, water quality testing is to monitor and measure the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, in order to evaluate the quality, safety and applicability of water bodies.

[0003] When conducting water quality testing, a water quality sampling device is needed. At present, the water quality sampling device generally uses a water pump to pump river water into a sampling bucket, and then takes the water sample in the sampling bucket into a sampling bottle to obtain the water sample. After obtaining the water sample, when sampling water samples at different depths, the water in the sampling bucket needs to be poured out. Therefore, the operation is cumbersome, and improper operation may cause water sample contamination during the process of taking out the water in the bucket, thereby affecting the accuracy of water quality testing.

[0025] Description of reference numerals: DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] like Figures 1 to 5As shown, the utility model provides a water quality sampling device for environmental monitoring, including a mounting plate 1, on which a hose reel 2, a water pump 3 and a sampling box 5 are respectively arranged, a water pumping pipe 8 is wound around the hose reel 2, one end of the water pumping pipe 8 is connected to the water pump 3, and the other end of the water pumping pipe 8 is connected to a water pumping head 82, and a water outlet pipe 4 is connected between the water pump 3 and the sampling box 5; a box cover 51 is arranged on the sampling box 5, and a water outlet hole 510 is arranged on the box cover 51, and the outlet hole 510 is arranged on the box cover 51. The water pipe 4 is fixed in the water outlet 510, and two relatively arranged sampling bottle fixing devices are provided inside the sampling box 5, and the sampling bottle fixing device includes a damping rod 53 and an arc limit plate 54. One end of the damping rod 53 is fixed on the inner wall of the sampling box 5, and the other end is fixedly connected to the arc limit plate 54. A spring 52 is sleeved on the surface of the damping rod 53, and one end of the spring 52 is fixedly connected to the inner wall of the sampling box 5, and the other end is fixedly connected to the arc limit plate 54.

[0029] The utility model provides a sampling box 5, places the sampling bottle in the sampling box 5, and fixes the sampling bottle through a sampling bottle fixing device, so as to avoid the sampling bottle from shaking or tipping over during the sampling process. During sampling, the water pump 3 draws water into the water outlet pipe 4 through the water pumping pipe 8, and then enters the sampling bottle through the water outlet hole 510 on the box cover 51. When the sampling is completed, the box cover 51 is opened, the sampling bottle is taken out, and the water quality test can be directly carried out; when it is necessary to test the water quality at different depths, another sampling bottle can be placed in the sampling box 5, and the above operation can be repeated, so the operation is very convenient, and the water directly flows into the sampling bottle, which can ensure the accuracy of the water quality test.

[0030] Among them, Figure 2 and Figure 3 As shown, the sampling bottle fixing device includes a damping rod 53 and an arc limit plate 54. When placing the sampling bottle, first pull the arc limit plate 54 on one side toward the inner wall of the sampling box 5 to compress the damping rod 53 and the spring 52, and place the bottle body of the sampling bottle against the arc limit plate 54 on the other side, and then release the previous arc limit plate 54. The damping rod 53 and the spring 52 automatically reset under the elastic effect, so that the arc limit plates 54 on both sides can be well squeezed on the surface of the sampling bottle, thereby fixing the sampling bottle in the sampling box 5, and different types of sampling bottles can be well fixed, greatly improving the practicality of the device. Preferably, the inner surface of the arc limit plate 54 is provided with a rubber pad. By providing a rubber pad, the sampling bottle can be better protected and prevented from being squeezed and damaged.

[0031] In addition, since the two sampling bottle fixing devices are arranged relative to each other, the sampling bottle is located in the middle of the sampling box 5 after being fixed. Therefore, the water outlet hole 510 on the box cover 51 is preferably arranged in the middle of the box cover 51, so as to correspond to the bottle mouth of the sampling bottle, so as to facilitate the water flow to enter the sampling bottle better. Preferably, a water outlet cylinder 511 connected to the water outlet hole 510 is provided on the bottom surface of the box cover 51. By providing the water outlet cylinder 511, the water in the water outlet pipe 4 can be better guided to enter the sampling bottle through the water outlet cylinder 511.

[0032] Preferably, one side of the box cover 51 is hinged on the side wall of the sampling box 5, and the other side is snap-fitted to the side wall of the sampling box 5. Therefore, when the sampling bottle needs to be placed or taken out, only one side of the box cover 51 needs to be opened, making the operation more convenient. Furthermore, a transparent observation window can be provided on the box body of the sampling box 5, through which the water level in the sampling bottle can be observed. When the water level in the sampling bottle reaches the required water level for sampling, the water pump 3 can be turned off and the sampling bottle can be taken out.

[0033] On the other hand, the utility model winds the water extraction pipe 8 on the hose reel 2, and the hose reel 2 drives the water extraction pipe 8 to be released to a suitable length, so that water areas at different depths at the same location can be sampled, thereby improving the practicability of the device.

[0034] Specifically, Figure 4 As shown, the hose reel 2 includes two brackets 21 arranged opposite to each other, the two brackets 21 are fixed on the mounting plate 1, a pay-off roller 22 is rotatably mounted between the two brackets 21, and the water pumping pipe 8 is wound around the pay-off roller 22. When in use, the pay-off roller 22 can be rotated according to the depth of water pumping, so that the water pumping pipe 8 is released to a suitable length. When the sampling is completed, the pay-off roller 22 is rotated in the opposite direction so that the water pumping pipe 8 is wound around the pay-off roller 22, so that the water pumping pipe 8 is retracted. Therefore, by setting the hose reel 2, waters of different depths at the same location can be sampled, thereby improving the practicality of the device. Preferably, a scale line 81 is provided on the water pumping pipe 8. By setting the scale line 81 on the water pumping pipe 8, accurate depth sampling can be performed.

[0035] Preferably, one end of the pay-off roller 22 passes through the bracket 21 and is connected to a positioning plate 23, a handle 24 is fixedly connected to the positioning plate 23, a pin 25 is movably inserted on the positioning plate 23, and the bracket 21 is provided with a pin hole 210 that is distributed circumferentially and matches the pin 25. By providing the handle 24, the pay-off roller 22 can be driven to rotate by turning the handle 24, so that the water pumping pipe 8 can be released or recovered conveniently. By providing the pin 25 and the pin hole 210, when the pay-off roller 22 is rotated by the handle 24 and the water pumping pipe 8 is released to a suitable length, the pin 25 is inserted into the pin hole 210, so that the handle 24 is limited to prevent the handle 24 from rotating, and when the handle 24 needs to be turned to recover the water pumping pipe 8, the pin 25 can be pulled out from the pin hole 210.

[0036] More preferably, if Figure 1 As shown, the mounting plate 1 is provided with a fixed pulley 6, and a limiting cylinder 7 is fixed on the outer wall of the mounting plate 1. One end of the water pumping pipe 8 passes through the fixed pulley 6 and enters the limiting cylinder 7, and passes out from the limiting cylinder 7 to be connected to the water pumping head 82. By providing the fixed pulley 6 and the limiting cylinder 7, the water pumping pipe 8 can be limited to ensure the stability of the water pumping pipe 8 during the release and recovery process. Among them, the limiting cylinder 7 can be welded to the outer wall of the mounting plate 1, and can also be fixed to the outer wall of the mounting plate 1 by screws.

[0037] Furthermore, if Figure 1 and Figure 5 As shown, a mesh filter cover 9 is installed on the water pumping pipe 8, and the water pumping head 82 is located inside the mesh filter cover 9. Since there are many impurities and weeds in the river water, the water pumping pipe 8 will be blocked during the water pumping process. By setting the mesh filter cover 9, these impurities and weeds can be filtered out to ensure the smooth progress of the water pumping process.

[0038] Furthermore, if Figure 1 As shown, the mounting plate 1 is provided with a threaded hole 11. By providing the threaded hole 11, the mounting plate 1 can be fixed on the hull during sampling, and the entire water quality sampling device can be driven by the hull to move, so as to sample river water at different positions. Of course, the mounting plate 1 can also be used alone.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
