Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum sampling, in particular to a surface water petroleum sampling device. Background Art

[0002] The petroleum in surface water mainly comes from industrial wastewater and domestic sewage. After entering the water body, petroleum pollutants will change the physical, chemical and biological properties of the water body, deteriorate the water quality, endanger the growth and reproduction of aquatic organisms, and even endanger human health. Therefore, it is necessary to sample and test the concentration and distribution of petroleum pollutants in surface water in order to understand the degree of water pollution. The steps for sampling petroleum are: first destroy the oil film that may exist in the surface water, put the sampling bottle 30cm away from the water surface, collect columnar water samples, and after collecting the samples, there should be appropriate space left in the sampling bottle, and all the substances in the sampling bottle should be used for determination. At present, when sampling petroleum, after the sampling bottle enters the surface water, it is impossible to accurately know the amount of water in the sample in the sampling bottle, and the general situation can only be judged based on work experience, which may cause the sample in the sampling bottle to be full. Since the density of petroleum substances is lower than that of water, they basically float on the water surface. When the sampling bottle is full, petroleum substances will flow out with the overflowing water, affecting the detection of petroleum in surface water, thereby increasing the difficulty of the sampler's work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0018] Example 1

[0019] The surface water petroleum sampling device described in this embodiment is as follows: Figure 1As shown, it includes a sampling bottle body 1, a bottle stopper 9 is arranged at the bottle mouth of the sampling bottle body 1, a connecting rope 8 is fixed on the top of the bottle stopper 9, and a floating ball 7 is connected to the movable end of the connecting rope 8. A water inlet pipe 10 connected to the bottle mouth is arranged on the inner wall of the sampling bottle body 1, and a blocking plate 12 for blocking the water outlet end of the water inlet pipe 10 is arranged in the sampling bottle body 1. Two floating plates 5 are arranged on the blocking plate 12. The bottle mouth of the sampling bottle body 1 is plugged with a bottle stopper 9, and the bottle stopper 9 The bottle stopper 9 is in transitional fit with the bottle mouth of the sampling bottle body 1, and the transitional fit can be a clearance fit or an interference fit. A fixing ring is welded or glued on the top of the bottle stopper 9, one end of the connecting rope 8 is wound around the fixing ring, and the other end of the connecting rope 8 is glued to the float 7, and an elastic rope is glued to the bottle stopper 9, and the movable end of the elastic rope is glued to the bottle body of the sampling bottle body 1. When the bottle stopper 9 is pulled out from the bottle mouth of the sampling bottle body 1, the bottle stopper 9 will not be lost under the action of the elastic rope, and it can be used. , using the existing fixing frame, put the sampling bottle body 1 into the fixing frame, use the lifting rope on the fixing frame to put the fixing frame and the sampling bottle body 1 into the surface water or take it out of the surface water after collecting the sample, after putting the sampling bottle body 1 into the surface water, the sampling bottle body 1 sinks into the water under the action of gravity, the length of the connecting rope 8 is less than 30cm, the distance from the bottle mouth of the sampling bottle body 1 to the floating ball 7 is fixed, when the sampling bottle body 1 reaches a depth of 30cm, the bottle stopper 9 is pulled out from the bottle mouth of the sampling bottle body 1, so that the sampling bottle body 1 can collect petroleum samples of a certain depth, when the sampling bottle body 1 sinks into the surface water, the floating ball 7 floats on the water surface due to the buoyancy, and the floating ball 7 pulls the bottle stopper 9 through the connecting rope 8, under the pulling force of the connecting rope 8 and the gravity of the sampling bottle body 1, the connecting rope 8 drives the bottle stopper 9 to be pulled out from the bottle mouth of the sampling bottle body 1, and the petroleum sample enters the sampling bottle body 1 through the bottle mouth, and the sampling is completed;

[0020] An inlet pipe 10 is adhered to the inner top of the sampling bottle body 1, and the inlet pipe 10 is connected to the bottle mouth of the sampling bottle body 1. A blocking plate 12 is arranged inside the sampling bottle body 1, and two symmetrically distributed floating plates 5 are arranged on the side wall of the blocking plate 12. When in use, the petroleum sample enters from the bottle mouth of the sampling bottle body 1, and then flows into the sampling bottle body 1 through the inlet pipe 10. As the water level in the sampling bottle body 1 increases, the floating plate 5 drives the blocking plate 12 to gradually approach the water outlet end of the inlet pipe 10 until the blocking plate 12 blocks the water outlet end of the inlet pipe 10. At this time, the petroleum sample no longer flows into the sampling bottle body 1, and because there is a certain distance from the inlet pipe 10 to the top of the sampling bottle body 1, the petroleum sample in the sampling bottle body 1 is not overflowed, and the sampling bottle body 1 can be taken out from the surface water.

[0021] like Figure 1As shown, two symmetrically distributed hanging ears 6 are fixed on the sampling bottle body 1. Two symmetrically distributed hanging ears 6 are glued on the sampling bottle body 1. The sampling bottle body 1 can be fixed on the fixing frame of the prior art by using the hanging ears 6. If there is no fixing frame, the pulling rope can be wound around the hanging ears 6, so as to put the sampling bottle body 1 into the surface water and take the sampling bottle body 1 out of the surface water;

[0022] like Figure 1 As shown, a seeding block 13 is fixed at the bottom of the sampling bottle body 1, and the seeding block 13 is pasted on the bottom of the sampling bottle body 1. The seeding block 13 can be made of waterproof alloy steel, so that the sampling bottle body 1 is easier to sink, and the sampling bottle body 1 is less skewed as much as possible after being affected by buoyancy, so that it can better sample petroleum samples;

[0023] like Figure 1 As shown, the outer surface of the sampling bottle body 1 is sprayed with anti-rust paint, which can enhance the anti-rust, anti-oxidation and anti-corrosion properties of the sampling bottle body 1 and extend the service life of the sampling bottle body 1 as much as possible;

[0024] like Figure 1 As shown, a scale is provided on the connecting rope 8, and the scale on the connecting rope 8 enables the sampler to visually check the length of the connecting rope 8, which is convenient for operation;

[0025] During actual use, the sampling bottle body 1 is placed in surface water. Under the gravity of the sampling bottle body 1, the sampling bottle body 1 continues to sink. Under the buoyancy of the float 7, the float 7 drives the bottle stopper 9 to be pulled out from the bottle mouth of the sampling bottle body 1 through the connecting rope 8. The petroleum sample passes through the bottle mouth and the water inlet pipe 10 and then flows into the sampling bottle body 1 from the water outlet end of the water inlet pipe 10. As the water in the sampling bottle body 1 continues to increase, the floating plate 5 drives the blocking plate 12 to float on the water surface in the sampling bottle body 1 until the blocking plate 12 blocks the water outlet end of the water inlet pipe 10. At this time, there is still appropriate space left in the sampling bottle body 1, the petroleum sample in the sampling bottle body 1 is not full, and the petroleum will not overflow from the sampling bottle body 1. The sampling bottle body 1 is then taken out from the surface water, so that the petroleum sample can be sampled better.

[0026] Example 2

[0027] This embodiment further illustrates the technology. Figure 1As shown, the inner wall of the sampling bottle body 1 is provided with two slide grooves 2, and a slider 3 is provided in the slide groove 2 to slide with the slide groove 2 and fixed on the floating plate 5. The inner wall of the sampling bottle body 1 is provided with two symmetrically distributed slide grooves 2, and a slider 3 is provided in the slide groove 2 to slide with the slide groove 2. The slider 3 is adhered to the side wall of the floating plate 5. When the floating plate 5 drives the blocking plate 12 to float on the water surface, the slider 3 slides up and down in the slide groove 2 to limit the movement trajectory of the floating plate 5, so that the blocking plate 12 can accurately block the water outlet end of the water inlet pipe 10.

[0028] A magnet 4 is fixed on the top of the chute 2, and a magnet 4 is pasted on the top of the chute 2. The slider 3 is made of metal material, and the slider 3 is an iron block, which attracts the magnet 4. When the blocking plate 12 blocks the water outlet of the water inlet pipe 10, the slider 3 contacts the magnet 4 on the top of the chute 2, thereby fixing the blocking plate 12 on the water outlet of the water inlet pipe 10, thereby blocking the water inlet pipe 10, avoiding excessive petroleum samples in the sampling bottle body 1, and preventing external water from flowing into the sampling bottle body 1;

[0029] A sealing plug 11 is provided on the top of the sealing plate 12 for plugging into the water outlet end of the water inlet pipe 10. The sealing plug 11 is adhered to the top of the sealing plate 12. When the sealing plate 12 blocks the water outlet end of the water inlet pipe 10, the sealing plug 11 on the top of the sealing plate 12 is plugged into the water outlet end of the water inlet pipe 10, thereby further sealing the water outlet end of the water inlet pipe 10 to achieve better sealing effect and prevent more petroleum samples from entering the sampling bottle body 1. After the sampling bottle body 1 is taken out of the surface water, a stick is inserted into the sampling bottle body 1 to push the sealing plug 11 out of the water outlet end of the water inlet pipe 10, so that the water outlet end of the water inlet pipe 10 is unobstructed, thereby taking out the petroleum sample in the sampling bottle body 1 for testing.
