Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a water quality testing sampling device. Background Technology

[0002] Water quality is short for water quality. It indicates the physical (such as color, turbidity, odor, etc.), chemical (content of inorganic and organic matter), and biological (bacteria, microorganisms, plankton, benthic organisms) characteristics and composition of water bodies. Water quality defines a series of water quality parameters and standards to evaluate the quality of water bodies. Water quality testing can assess the degree of pollution in water bodies. Water quality testing requires the use of sampling devices to collect samples.

[0003] Currently, when collecting water quality samples in locations where it is difficult for personnel to lower the sampling bucket, the sampling personnel use a telescopic sampling rod with a sampling rope to lower the sampling bucket from the top of the rod. However, when the top of the sampling rod slides over the sampling rope to lower the sampling bucket, it is necessary to hold both the sampling rod and the sampling rope at the same time. After the sampling bucket is filled with water and becomes heavier, it is quite strenuous to lift the sampling bucket by holding the sampling rod and pulling the sampling rope, making water quality sampling inconvenient. To address this, we propose a water quality sampling device. Utility Model Content

[0004] The main objective of this invention is to provide a water quality testing and sampling device. By improving the existing sampling rod used for water quality sampling and providing a corresponding support structure, the sampling personnel can sit on the frame. The sampling rod, consisting of a main branch pipe and a secondary branch pipe, is supported by a fixed insert above the double-ended bridge plate. The sampling bucket, with the sampling rope tied to it, can slide down through the L-shaped rope groove at the head of the secondary branch pipe, allowing the sampling rope to suspend the sampling bucket and lower it into the water for sampling and then pull it back up. This eliminates the need for the sampling personnel to hold the sampling rod and pull back the sampling bucket with both hands, effectively solving the problem of difficulty in lifting the sampling bucket after it becomes heavy due to water ingress. This enables easy operation of water quality testing and sampling. Furthermore, the fixed insert can work with the T-shaped bottom bolt plate at the central perforated plate to rotate and change the position of the main branch pipe, secondary branch pipe, and the suspended sampling bucket. This eliminates the need for the sampling personnel to extend their arms into dangerous areas to lower the sampling bucket; they can simply rotate the L-shaped handle to adjust the position of the sampling bucket, reducing the sampling risk for water quality sampling personnel in complex environments and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A water quality testing sampling device includes a double-ended bridge plate, a support plate, a base frame, and a sampling auxiliary rod. The double-ended bridge plate has a support plate and a base frame welded to its double-ended surfaces, and a central perforated plate is welded to the top of the double-ended plates. A T-shaped bottom bolt plate is rotatably installed at the hole of the central perforated plate, and a fixed insertion cylinder is welded to the top of the T-shaped bottom bolt plate. A sampling auxiliary rod is inserted into the cylinder of the fixed insertion cylinder. The sampling auxiliary rod includes a main branch pipe, a secondary branch pipe, a rotating shaft, a suspension rope plate, and a tail frame insertion rod. A secondary branch pipe is screwed into one end of the main branch pipe, and the main branch pipe is pinned into the cylinder of the fixed insertion cylinder. A rotating shaft welded to the surface of the suspension rope plate is screwed into the secondary branch pipe at the end away from the main branch pipe, and an L-shaped rope groove is opened through the surface of the suspension rope plate on one side of the rotating shaft. A tail frame insertion rod is inserted between the long straight groove wall of the L-shaped rope groove and the suspension rope plate.

[0007] Furthermore, a bottom bolt body of a T-shaped bottom bolt plate extends downward through the hole of the central hole plate, and a locking nut is screwed onto the bottom bolt body of the T-shaped bottom bolt plate extending through the central hole plate.

[0008] By adopting the above technical solution, the bottom bolt of the T-shaped bottom bolt plate can pass through the middle hole plate and be screwed to the locking nut, so that the bolt of the T-shaped bottom bolt plate can rotate at the middle hole plate.

[0009] Furthermore, a pin-fixing hole is provided between the cylinder body of the fixed insert and the pipe wall of the main branch pipe, and a T-shaped pin is inserted between the fixed insert and the pin-fixing hole of the main branch pipe.

[0010] By adopting the above technical solution, after the main branch pipe is inserted into the fixed insertion cylinder, a T-shaped pin can be inserted into the fixed hole to lock it, so that the main branch pipe can rotate with the fixed insertion cylinder.

[0011] Furthermore, a screw-in connector is screwed into the other end of the main branch pipe away from the fixed insert, and the head of the screw-in connector is welded to one end of the secondary branch pipe.

[0012] By adopting the above technical solution, the secondary branch pipe can be screwed and installed at the main branch pipe using a swivel joint.

[0013] Furthermore, an insertion hole is provided through the long straight groove wall of the L-shaped rope groove and the rope plate, and a tail frame rod is vertically inserted into the insertion hole, and a U-shaped frame plate covering the rope plate is welded to the rod body of the tail frame rod.

[0014] By adopting the above technical solution, after the sampling rope is tied to the sampling bucket, the sampling rope can slide from the long straight groove of the L-shaped rope groove into the vertical groove cavity. Then, by using the tailstock rod inserted into the insertion hole, it can be stopped at the long straight groove cavity of the L-shaped rope groove, so that the sampling rope can be pulled out or lowered at the vertical groove cavity of the L-shaped rope groove.

[0015] Furthermore, an L-shaped handle is welded to one side of the bottom plate of the fixed insertion cylinder, and a long handle extends from the handle body towards the base frame.

[0016] By adopting the above technical solution, holding the L-shaped handle allows the fixed insertion cylinder to rotate at the central hole plate with the T-shaped bottom bolt plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model improves the existing sampling rod used for water quality sampling and sets up a corresponding support structure. The sampling personnel can sit on the seat frame, and the sampling rod composed of the main branch pipe and the secondary branch pipe is supported by a fixed insertion cylinder above the double-headed bridge plate. The sampling bucket with the sampling rope tied can slide down at the L-shaped rope groove of the rope plate at the head of the secondary branch pipe, so that the sampling rope can suspend the sampling bucket and lower it into the water for sampling and pull it up. This allows the sampling personnel to pull back the sampling bucket with both hands without holding the sampling rod, effectively solving the problem of the difficulty of lifting the sampling bucket after it is filled with water and becomes heavier, and realizing easy operation of water quality testing and sampling.

[0019] Furthermore, the fixed insertion tube can be used in conjunction with the T-shaped bottom plug plate to rotate and change the position of the main branch pipe, the secondary branch pipe, and the suspended sampling bucket at the orifice plate. This allows sampling personnel to adjust the position of the sampling bucket simply by rotating the L-shaped handle without having to reach into the danger zone to lower the sampling bucket, thus reducing the sampling risk for water quality sampling personnel in complex environments.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a water quality testing sampling device includes a double-ended bridge plate 1, a support plate 2, a base frame 3, and a sampling auxiliary rod 9. The support plate 2 and the base frame 3 are welded to the surfaces of the two ends of the double-ended bridge plate 1, respectively. A central perforated plate 4 is welded to the top of the two sets of plates of the support plate 2. A T-shaped bottom plug plate 5 is rotatably installed at the hole of the central perforated plate 4, and a fixed insertion cylinder 7 is welded to the top of the T-shaped bottom plug plate 5. The sampling auxiliary rod 9 is inserted into the cylinder of the fixed insertion cylinder 7. The sampling auxiliary rod 9 includes a main branch pipe 10 and a secondary branch pipe 1. 2. A rotating shaft 13, a rope plate 14, and a tailstock insert rod 16 are provided. A secondary branch pipe 12 is screwed into one end of the main branch pipe 10, and the main branch pipe 10 is inserted into the cylinder of the fixed insert cylinder 7. A rotating shaft 13 welded to the surface of the rope plate 14 is screwed into the secondary branch pipe 12 away from the main branch pipe 10. An L-shaped rope groove 15 is provided through the surface of the rope plate 14 on one side of the rotating shaft 13. A tailstock insert rod 16 is inserted between the long straight groove wall of the L-shaped rope groove 15 and the rope plate 14.

[0027] Wherein, a bottom bolt body of a T-shaped bottom bolt plate 5 extends downward through the hole of the central hole plate 4, and a locking nut 6 is screwed onto the T-shaped bottom bolt plate 5 where it extends through the bottom bolt body of the central hole plate 4.

[0028] By adopting the above technical solution, the bottom bolt of the T-shaped bottom bolt plate 5 can pass through the middle hole plate 4 and be screwed to the locking nut 6, so that the bolt of the T-shaped bottom bolt plate 5 can rotate at the middle hole plate 4.

[0029] Wherein, a pin fixing hole is opened between the cylinder body of the fixed insertion cylinder 7 and the pipe wall of the main branch pipe 10, and a T-shaped pin 17 is inserted between the fixed insertion cylinder 7 and the pin fixing hole of the main branch pipe 10.

[0030] By adopting the above technical solution, after the main branch pipe 10 is inserted into the fixed insertion cylinder 7, it can be stopped by inserting a T-shaped pin 17 into the pin fixing hole, so that the main branch pipe 10 can rotate with the fixed insertion cylinder 7.

[0031] Among them, a screw connector 11 is screwed into the other end of the main branch pipe 10 away from the fixed insertion cylinder 7, and the head of the screw connector 11 is welded to one end of the secondary branch pipe 12.

[0032] By adopting the above technical solution, the secondary branch pipe 12 can be screwed and installed at the main branch pipe 10 using the screw joint 11.

[0033] Wherein, the long straight groove wall of the L-shaped rope groove 15 is provided with an insertion hole through the rope plate 14, and a tail frame rod 16 is vertically inserted into the insertion hole, and a U-shaped frame plate covering the rope plate 14 is welded to the rod body of the tail frame rod 16.

[0034] By adopting the above technical solution, after the sampling rope is tied to the sampling bucket, the sampling rope can slide from the long straight groove of the L-shaped rope groove 15 into the vertical groove cavity. Then, the tailstock rod 16 can be inserted into the insertion hole to stop at the long straight groove cavity of the L-shaped rope groove 15, so that the sampling rope can be pulled out or lowered at the vertical groove cavity of the L-shaped rope groove 15.

[0035] Among them, an L-shaped handle 8 is welded to one side of the bottom cylinder plate of the fixed insertion cylinder 7, and a long handle rod extends from the handle body of the L-shaped handle 8 toward the seat frame 3.

[0036] By adopting the above technical solution, holding the L-shaped handle 8 allows the fixed insertion cylinder 7 to rotate at the center hole plate 4 with the T-shaped bottom bolt plate 5.

[0037] It should be noted that this utility model is a water quality testing sampling device. By improving the existing sampling rod used for water quality sampling and providing a corresponding support structure, the sampling rope can be pre-tied to the sampling bucket during water quality sample collection. Then, a double-ended bridge plate 1 is placed near the sampling point where it is difficult for the sampling personnel to lower the sampling bucket. Subsequently, the T-shaped bolt plate 5 can pass through the central hole plate 4 above the support plate 2 and be screwed onto the locking nut 6, allowing the T-shaped bolt plate 5 to rotate at the central hole plate 4. Then, the suspension rope... Plate 14 can be screwed onto the secondary branch pipe 12 via shaft 13. At the same time, the secondary branch pipe 12 can be screwed onto the main branch pipe 10 via screw connector 11. At this time, the main branch pipe 10 can be inserted into the fixed insertion cylinder 7 and connected by T-pin 17. Then, the sampling rope can slide from the long straight groove of the L-shaped rope groove 15 into its vertical groove. Subsequently, the tailstock insertion rod 16 is inserted into the insertion hole and can be stopped at the long straight groove of the L-shaped rope groove 15, so that the sampling rope can be pulled out or lowered at the vertical groove of the L-shaped rope groove 15.

[0038] The sampling personnel can sit on the surface of the frame 3, stepping on the middle section of the double-ended bridge plate 1. They then grasp the L-shaped handle 8 and pull the sampling rope while rotating the fixed insertion cylinder 7. The fixed insertion cylinder 7, along with the main branch pipe 10, the secondary branch pipe 12, and the sampling bucket, moves to the sampling placement point. The sampling personnel then place one foot on the ground, while the foot on the double-ended bridge plate 1 can be positioned on the fixed insertion cylinder 7 on the surface of the perforated plate 4. The sampling personnel can then lower the sampling rope with both hands. After the sampling rope slides down through the L-shaped rope groove 15, the sampling bucket descends into the water for sampling. The sampling personnel can visually inspect the sampling bucket or rely on the sound of it hitting the water and their experience with the rope length to determine if a sample has been collected. After watering, the sampling personnel can pull the sampling rope back to raise the sampling bucket to the rope plate 14. The sampling rope can then be temporarily tied to the L-shaped handle 8. The sampling personnel can then lower their feet from the fixed insertion tube 7 onto the double-ended bridge plate 1, and then operate the main branch pipe 10 and the auxiliary branch pipe 11 to rotate the sampling bucket to the ground position while holding the L-shaped handle 8. The sampling rope temporarily tied to the L-shaped handle 8 can then be untied. The sampling personnel can then leave the seat frame 3, and the auxiliary branch pipe 12 can be tilted forward and pressed against the ground. The sampling personnel can then directly pull out the tail frame insertion rod 16, slide the sampling rope out from the L-shaped rope groove 15, and pour the water in the sampling bucket into the sampling storage container for preservation and testing.

[0039] Then, the T-pin 17 can be pulled out to separate the main branch tube 10 from the fixed insertion tube 7. At the same time, the screw joint 11 between the main branch tube 10 and the secondary branch tube 12 can also be screwed apart, which facilitates the carrying of the sampling device.
