Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water intake device for water quality detection. Background Art

[0002] Water quality testing is widely used in the fields of meteorological parameter measurement, water environment evaluation and water supply and drainage network safety monitoring. When conducting water quality testing, it is necessary to first collect water samples using a water sampling device, and then transport the water samples to the laboratory to measure the designated items of the water samples.

[0003] The utility model with patent publication number CN210802986U discloses a sampling device for water source detection of water supply and drainage, including a sampling container, a sealing groove is provided on one side of the middle part of the top of the sampling container, a water inlet hole is provided in the middle part of the bottom end of the sealing groove, a sealing plate is installed on one side of the edge of the top end of the sealing groove, a rubber sealing pad is bonded to one end of the sealing plate, and a limiting buckle is welded on the top of the other end of the sealing plate. The utility model has a scientific and reasonable structure and is safe and convenient to use. The sampling container can be sealed by the sealing groove, the water inlet hole, the sealing plate and the rubber sealing pad to prevent the sampling container from infiltrating non-sampling water when it moves underwater and affecting the detection result of the sampled water. The water intake position can be controlled by the nylon lifting rope and the sealing plate to improve the accuracy of water intake. The difficulty of resetting the sealing plate can be reduced by the spring and the fixing block, which is conducive to reducing the difficulty of use for the staff and facilitating the use of the staff.

[0004] In the above technical solution, in order to prevent water samples from non-required water layers from entering the sampling container, a sealing plate is provided at the water inlet. However, the opening and closing of the sealing plate needs to be controlled by a nylon lifting rope. During actual operation, the nylon lifting rope is easily tangled with the traction rope, affecting its water extraction efficiency. At the same time, there is a lack of filtering mechanism at the water inlet. When it is necessary to sample the water sample at the liquid surface, impurities floating on the liquid surface will also enter the water inlet with the water flow, affecting the water extraction effect of the sampling device.

[0041] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] like Figure 1-8 As shown, a water intake device for water quality detection of the utility model comprises a water intake bucket 1, an isolation cover 2, a pulling rope 3 and a counterweight block 4.

[0043] The water bucket 1 is used for collecting water samples. An opening 101 is provided on the water bucket 1. When the water bucket 1 is placed in water, the water sample can enter the water bucket 1 along the opening 101 for storage.

[0044] The isolation cover 2 is used to filter impurities floating on the liquid surface. The isolation cover 2 includes a top plate 21 and a plurality of blocking rods 22, wherein the top plate 21 selectively blocks the opening 101 and has a water hole 201 therein. When the top plate 21 blocks the opening 101, the water sample can enter the water collection bucket 1 through the water hole 201. When the top plate 21 does not block the opening 101, the water sample directly enters the water collection bucket 1 through the opening 101. The plurality of blocking rods 22 are fixedly arranged on the same side of the top plate 21 and are arranged in a circular array and at intervals about the core line of the water hole 201, such as Figure 4 As shown, a plurality of barrier rods 22 are arranged in a circular array and at intervals, forming a grid-like structure, which can achieve a certain filtering effect. Figure 5 Under the working conditions shown, the water sample needs to first pass through the gap between adjacent blocking rods 22 and then enter the water intake bucket 1 through the water through hole 201, so as to block the larger impurities floating on the liquid surface and prevent them from entering the water intake bucket 1 and affecting the water intake effect of the water intake device.

[0045] like Figure 3 As shown, the water collection bucket 1 includes a limiting cylinder 11, a bottom barrel 12 and a flange 13, wherein the limiting cylinder 11 is a cylindrical structure, which can also be called a tubular structure, the opening 101 is located at one end of the limiting cylinder 11, the bottom barrel 12 is fixedly arranged at the end of the limiting cylinder 11 away from the opening 101, and is sealedly connected thereto, the interior of the bottom barrel 12 is connected to the interior of the limiting cylinder 11, so that the water sample enters the limiting cylinder 11 and the bottom barrel 12 in sequence through the opening 101 for storage; the flange 13 is fixedly arranged at the end of the limiting cylinder 11 away from the bottom barrel 12, and the flange 13 is as shown in FIG. Figure 3 As shown, similar to the folded edge with an arc-shaped cross section, it not only increases the contact area of ​​the operator's hand-held water bucket 1, but also can be engaged with the operator's hand, so that the water bucket 1 can be carried by holding the flange 13, which facilitates the movement of the water bucket 1.

[0046] In order to allow the water bucket 1 to sink into the water quickly, it is preferred that the outer diameter of the bottom bucket 12 gradually decreases from the end close to the limiting cylinder 11 to the end away from the limiting cylinder 11, that is, it is made into a cone shape that is wide at the top and narrow at the bottom, so as to reduce the water entry resistance of the water bucket 1; similarly, the outer diameter of the limiting cylinder 11 can also be made smaller than the outer diameter of the bottom bucket 12. Of course, the outer diameter of the limiting cylinder 11 can also be made smaller than the inner diameter of the circular ring formed by the multiple blocking rods 22, and the outer diameter of the circular ring formed by the multiple blocking rods 22 can be made smaller than the outer diameter of the end of the bottom bucket 12 close to the limiting cylinder 11, such as Figure 2 and Figure 6 As shown, during use, the limiting cylinder 11 is placed inside a circular cavity surrounded by a plurality of blocking rods 22, which also has the effect of reducing resistance.

[0047] Specifically, the limiting cylinder 11 is preferably configured as a cylindrical structure to avoid interference and collision with the blocking rod 22 during movement.

[0048] The pulling rope 3 is used to be held by the operator to control the up and down movement of the water-drawing device. The pulling rope 3 passes through the water hole 201, and one end of the pulling rope 3 is fixedly arranged in the water-drawing bucket 1. The accompanying drawings only show that the pulling rope 3 is located at the bottom of the water-drawing bucket 1. In order to ensure the stability of the water-drawing bucket 1, the pulling rope 3 can also be fixed at other positions. The outer diameter of the pulling rope 3 is smaller than the inner diameter of the water hole 201 to allow the water sample to pass through the water hole 201; the operator holds the pulling rope 3 at one end away from the water-drawing bucket 1 to lift and lower the pulling rope 3 to perform water-drawing operations.

[0049] The counterweight 4 is used to increase the weight of the corresponding component so that the corresponding component sinks into the water. When the blocking rod 22 is located on the side of the top plate 21 close to the water bucket 1, the counterweight 4 is fixedly set on the water bucket 1 to allow the water bucket 1 to sink into the water; when the blocking rod 22 is located on the side of the top plate 21 away from the water bucket 1, the counterweight 4 is fixedly set on the top plate 21 to allow the top plate 21 to sink into the water.

[0050] This water sampling device can not only collect water samples at the liquid surface, but also collect water samples at the liquid surface. Figure 5 , and can also collect water samples below the liquid surface. For specific operations, see Figure 6 The difference between the two operations is not only the different installation positions of the counterweight 4, but also the need to turn over the isolation cover 2 so that the blocking rod 22 is located on the upper or lower side of the top plate 21. In order to improve the switching efficiency of the above two operations and simplify the water intake steps, Figure 7 As shown, a plurality of barrier rods 22 may be provided on both sides of the top plate 21 , and the plurality of barrier rods 22 on each side of the top plate 21 are arranged in a circular array about the core line of the water hole 201 and are spaced apart, and the counterweight block 4 is fixedly provided on the water bucket 1 or the top plate 21 .

[0051] Further, such as Figure 7 As shown, the isolation cover 2 also includes a drainage tube 23, one end of which is fixedly arranged on a side of the top plate 21 close to the water collection bucket 1 and is connected to the water through hole 201, and the drainage tube 23 is selectively inserted into the opening 101. When the water sample on the liquid surface is taken, the water sample can enter the water collection bucket 1 through the drainage tube 23. The drainage tube 23 has a certain guiding effect, which can reduce the splashing range of the water sample and maintain the stability of the water collection device.

[0052] The counterweight block 4 includes a connecting rod 41 and a weight block 42, wherein the connecting rod 41 is fixedly arranged on the water bucket 1 and the top plate 21; the weight block 42 is fixedly arranged on the connecting rod 41 in a detachable manner, and the detachable fixed connection between the weight block 42 and the connecting rod 41 is utilized to realize the rapid adjustment of the position of the counterweight block 4; specifically, the weight block 42 can be configured as a circular ring structure, a threaded hole is opened inside the weight block 42, and the weight block 42 is connected to the connecting rod 41 by threaded cooperation.

[0053] In order to prevent the arrangement of the weight block 42 from causing the center of gravity of the water intake bucket 1 and the top plate 21 to shift, it is preferred to provide a plurality of connecting rods 41 on the water intake bucket 1 and the top plate 21, so that the plurality of connecting rods 41 on the water intake bucket 1 or the top plate 21 are arranged in a circular array about the center line of the water intake bucket 1, so that the center of gravity of the water intake device can be maintained on the center line.

[0054] The method of using the water taking device for water quality detection of the utility model is as follows:

[0055] When it is necessary to collect water samples at the liquid surface, first turn over the isolation cover 2, let the blocking rod 22 be located on the upper side of the top plate 21, let the pull rope 3 pass through the water hole 201, then install the counterweight 4 on the top plate 21, then put the water bucket 1 into the water storage well, and slowly lower the pull rope 3, as shown in FIG. Figure 5 As shown, the water bucket 1 and a part of the barrier rod 22 are sunk into the water (preferably, the middle position of the barrier rod 22 is flush with the liquid surface), so that the water sample at the liquid surface can flow into the water bucket 1 through the interval between two adjacent barrier rods 22 and the water hole 201 in sequence, and finally the pull rope 3 is moved upward to take the water bucket 1 out of the water storage well;

[0056] When it is necessary to collect water samples below the liquid level, first turn over the isolation cover 2, let the blocking rod 22 be located at the lower side of the top plate 21, and let the pull rope 3 pass through the water hole 201, then install the counterweight 4 on the water bucket 1, then put the water bucket 1 into the water storage well, and slowly lower the pull rope 3, as shown in FIG. Figure 6 As shown, the water bucket 1 is sunk into the water, and the water sample below the liquid surface can flow directly into the water bucket 1 through the opening 101. Finally, the pulling rope 3 is moved upward to take the water bucket 1 out of the water storage well. During this period, when the top plate 21 contacts the liquid surface, the blocking rod 22 is subjected to a smaller buoyancy and is inserted into the water, while the top plate 21 is subjected to a larger buoyancy and is floated on the water surface. At this time, the pulling rope 3 is lowered, and the water bucket 1 is separated from the top plate 21. At this time, the blocking rod 22 is inserted into the water and is located outside the water bucket 1. Therefore, larger impurities on the liquid surface will also be blocked by the blocking rod 22 and will not enter the water bucket 1. This can also prevent impurities floating on the liquid surface from entering the water bucket 1.

[0057] 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.
