Description

Technical Field

[0001] The utility model relates to the field of water body sampling equipment, in particular to a sewage sampling barrel. Background Art

[0002] At present, the water of rivers or lakes needs to be sampled and tested to determine the degree of pollution. Since there will inevitably be floating leaves or garbage and other debris in sewage (water bodies containing pollutants), the sewage needs to be initially filtered before pouring it into the sampling barrel to prevent leaves or garbage and other debris from entering the sampling barrel. Currently, the sewage is poured into the screen plate, and the sewage flows into the sampling barrel after being filtered by the screen plate, while the debris is intercepted in the screen plate. The sewage in the sampling barrel is then tested offline. However, since the screen plate and the sampling barrel are scattered, it is necessary to pick up the screen plate with one hand and pour the sewage into the screen plate with the other hand. As a result, the sewage is easily poured on the hands, and the operation is also very inconvenient. Moreover, in the process of transporting the sewage barrel, since the screen plate and the sampling barrel are scattered, it is easy to cause the screen plate to deform or break. Therefore, it is necessary to improve the sewage sampling barrel of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings.

[0022] The sewage sampling barrel of the utility model is as follows Figures 1 to 3 As shown, it includes a barrel body 1, and the barrel body 1 is covered with a barrel cover 2. Specifically, as Figure 5 As shown, the outer peripheral portion of the barrel cover 2 is formed with a hook ring groove 22. Figure 1 As shown, when the barrel cover 2 is covered on the barrel body 1, the hook ring groove 22 is adapted to be hooked on the barrel mouth edge of the barrel body 1, thereby preventing the barrel cover 2 and the barrel body 1 from being horizontally displaced relative to each other. Figures 1 to 3 As shown, a sieve plate 3 is provided on the barrel cover 2. Figure 6 and Figure 7 As shown, the sieve plate 3 includes a cylinder 30 and a sieve 31. The sieve 31 is arranged in the lower end of the cylinder 30. For example, a step structure is formed in the lower end of the cylinder 30, and the edge of the sieve 31 is placed on the step structure to prevent the sieve 31 from falling off the cylinder 30. Figure 7 As shown, the lower end of the barrel 30 is formed with an outer flange 301. Figure 4 and Figure 5 As shown, a water drop hole 201 is formed in the middle of the bucket cover 2, and a hook portion 21 is formed at the edge of the water drop hole 201. The hook portion 21 is located on the upper side of the bucket cover 2, and the hook portion 21 can be bonded to the bucket cover 2, such as Figure 1 As shown, the lower end of the sieve plate 3 is aligned with the drain hole 201, that is, the cylinder 30 and the drain hole 201 are arranged coaxially. Figure 2 As shown, the outer flange 301 is placed on the edge of the water hole 201, and the hook 21 is buckled with the outer flange 301, that is, the outer flange 301 is adapted to be clamped between the edge of the water hole 201 and the hook 21, so as to prevent the sieve plate 3 and the barrel cover 2 from shifting up and down relative to each other. Figure 3 and Figure 6 As shown, a notch 3011 for the hook 21 to pass through is formed on the outer flange 301. Therefore, when the sieve plate 3 needs to be disassembled for cleaning, the sieve plate 3 can be rotated by hand to rotate the notch 3011 to a position aligned with the hook 21, and then the sieve plate 3 is lifted upward, and the hook 21 can pass relatively through the notch 3011 to allow the sieve plate 3 to be separated from the barrel cover 2 upward.

[0023] like Figure 1As shown, when sewage sampling is performed, the sewage is poured into the sieve plate 3, and the cylinder 30 serves to prevent the sewage from splashing out. The sewage passes through the sieve 31, and debris such as leaves or garbage are intercepted by the sieve 31, while the water passes through the sieve 31 downward, and then flows downward into the barrel body 1. Since the barrel cover 2 supports the sieve plate 3, and the hook 21 is buckled with the outer flange 301, the user does not need to hold the sieve plate 3 with his hands during the process of pouring sewage, so as to avoid sewage splashing on his hands. Therefore, the sewage sampling barrel of the utility model is more convenient to use. When the amount of sewage sample is sufficient, the sieve plate 3 is disassembled, and then the debris in the sieve plate 3 is cleaned up, and then the notch 3011 is aligned with the hook 21, and the sieve plate 3 is lowered down so that the outer flange 301 is placed on the edge of the drain hole 201, and then the sieve plate 3 is rotated so that the outer flange 301 is rotated and buckled into the hook 21. During the transportation of the sewage sampling barrel, the hook 21 is buckled with the outer flange 301, so as to prevent the sieve plate 3 from falling off the barrel cover 2, and the barrel body 1 also plays a role of horizontal impact protection for the sieve plate 3, thereby preventing the sieve plate 3 from being easily deformed or damaged.

[0024] Furthermore, if Figure 6 As shown, the number of the notches 3011 is set to two, and the two notches 3011 are arranged at 180°. That is, the notches 3011 are symmetrically distributed on both sides of the central axis of the barrel 30. Figure 4 As shown, the number of hooks 21 is set to two, and the two hooks 21 are arranged at 180°. Figure 3 As shown, the hook 21 can buckle the left and right ends of the sieve plate 3, which is beneficial to balance the force of the sieve plate 3 and prevent the sieve plate 3 from jumping up during the transportation of the sewage sampling barrel. When the sieve plate 3 is rotated to make one of the notches 3011 align with the hook 21, the other notch 3011 also aligns with the corresponding hook 21 at the same time.

[0025] Furthermore, if Figure 7 As shown, the lower end of the barrel 30 is formed with a socket portion 302. Figure 1 and Figure 2 As shown, the socket portion 302 is adapted to be inserted into the drain hole 201, that is, the socket portion 302 is in a downwardly protruding shape, so when installing the sieve plate 3, after aligning the notch 3011 with the hook portion 21, the sieve plate 3 is moved down to insert the socket portion 302 into the drain hole 201, and then the sieve plate 3 is rotated to make the hook portion 21 buckle with the outer flange 301, so that the drain hole 201 radially (horizontally) positions the sieve plate 3, further avoiding accidental displacement of the sieve plate 3 during use, which is conducive to the smooth progress of sampling work.

[0026] Furthermore, if Figure 1 and Figure 2 As shown, a support frame 5 for supporting the filter paper 4 is provided in the upper end of the cylinder 30 (it should be noted that Figure 3The support frame 5 and the filter paper 4 are not shown. Figure 8 As shown, the support frame 5 includes a rod 51, such as Figure 1 and Figure 2 As shown, the end of the rod 51 is fixedly connected to the inner wall of the barrel 30. Figure 8 As shown, the rods 51 are evenly arranged around the center of the barrel 30; therefore, when the sewage needs to be filtered to a higher degree, the filter paper 4 can be placed on the support frame 5, and then the sewage can be poured on the filter paper 4 for filtration. The water penetrates the filter paper 4 and then flows down into the barrel 1. At this time, the screen 31 also plays a role of insurance, preventing the filter paper 4 from accidentally breaking and debris falling into the barrel 1. Figure 8 As shown, the support frame 5 can be radial, that is, the top projection of the rod 51 is on the diameter of the barrel 30, so that the support frame 5 has a better supporting effect on the center of the filter paper 4, preventing the center of the filter paper 4 from being easily broken. The material of the barrel 30 and the screen 31 can be stainless steel, so the edge of the screen 31 is welded to the above-mentioned step structure of the barrel 30, and the rod 51 can be a stainless steel round rod, and the end of the rod 51 is welded to the inner wall of the barrel 30. For example, the barrel 30 and the screen 31 can also be integrally formed by injection molding, and the support frame 5 can be bonded to the barrel 30.

[0027] Furthermore, if Figure 1 and Figure 8 As shown, the support frame 5 is in an arc-shaped concave shape. Since the filter paper 4 is soft, when it is impacted by sewage, the filter paper 4 will sink and deform, so that the filter paper 4 sticks to the support frame 5. The support frame 5 will position the filter paper 4 to prevent the filter paper 4 from shifting in the horizontal direction and to prevent the sewage from easily flowing to the outside of the sieve plate 3.

[0028] Furthermore, if Figure 3 and Figure 4 As shown, the barrel cover 2 is formed with a water extraction hole 202 on the outer side of the sieve plate 3. Figure 1 As shown, the pumping hole 202 is provided with a rubber plug 6, in other words, the rubber plug 6 is used to close the pumping hole 202. Specifically, a flange is formed at the upper end of the rubber plug 6, and the flange is placed on the edge of the pumping hole 202, and the lower end of the rubber plug 6 is inserted into the pumping hole 202 with an interference fit, thereby closing the pumping hole 202. When the sewage barrel of the utility model containing the sewage sample is transferred to the testing laboratory, the rubber plug 6 is taken out, and then the sewage sample in the barrel body 1 is pumped out using the existing barrel pump.
