Description

Technical Field

[0001] This utility model relates to the technical field of petroleum hydrocarbon detection, and in particular to a high-precision petroleum hydrocarbon detection system. Background Technology

[0002] Petroleum hydrocarbons are complex mixtures of hydrocarbons, primarily composed of hydrocarbons. With rapid economic development, petroleum hydrocarbon pollution has become a global problem. For example, the extraction, refining, and transportation of oil, as well as the frequent occurrence of various oil spills, have led to increasing soil pollution and damage. Total petroleum hydrocarbons (TPH) is the collective term for hydrocarbons in petroleum, and the TPH content in soil is now one of the important indicators for soil testing.

[0003] When detecting the total petroleum hydrocarbon content in soil, an extraction device is typically used to extract the total petroleum hydrocarbons from the soil. For example, a multi-stage extraction detection device for total petroleum hydrocarbons in soil disclosed in patent publication number CN114487222B includes a detection platform with a fixed base above it. Inside the fixed base are a first extraction device, a second extraction device, and a separation device. The second extraction device is located between the first extraction device and the separation device. This device can detect changes in the liquid level and viscosity of the extractant in the first extraction tank in real time through a temperature control mechanism and a magnetic plate and coil at the lower end of the stirring rod. This allows for automatic adjustment of the heating plate's temperature increase, preventing the extractant and petroleum hydrocarbons from volatilizing during extraction and affecting detection accuracy. The isolator reduces the problem of petroleum hydrocarbons volatilizing along with the extractant during separation. Furthermore, the isolator also creates turbulence within the extractant, increasing the volatilization rate.

[0004] The petroleum hydrocarbon detection device in the aforementioned patented technology also has the following drawbacks: the height of the detection platform is fixed and cannot be adjusted, which makes it inconvenient for staff to adjust the height of the detection platform according to their height. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a test platform with adjustable height, which can be adjusted according to the height of the staff during testing, bringing convenience to the staff's testing work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision petroleum hydrocarbon detection system, comprising a detection platform and an adjustment mechanism. A fixed base is provided at the top of the detection platform, and a first extraction device, a second extraction device, and a separation device are disposed inside the fixed base. The adjustment mechanism includes a base frame, with a dual-axis motor fixedly installed at the top inner side of the base frame. Transmission screws are fixedly connected to the output ends of both sides of the dual-axis motor. Two sets of transmission screws are symmetrically and rotatably mounted on the base frame, with opposite thread directions. Two sets of guide rods are fixedly connected to the inner side of the base frame, and sliding seats are screwed onto each of the two sets of transmission screws. The two sets of sliding seats are slidably mounted on the two sets of guide rods. Support plates are rotatably connected to the front and rear ends of the two sets of sliding seats. Four sets of clearance grooves are symmetrically opened at the top of the base frame, and receiving grooves are provided on the outer sides of each of the four clearance grooves. The support plates pass through the clearance grooves. Four sets of connecting seats are symmetrically fixed on both sides of the bottom of the detection platform, with the upper part of the support plates rotatably connected to the connecting seats, and the connecting seats being positioned above the receiving grooves.

[0007] Preferably, two sets of support beams are symmetrically fixedly connected to the inner side of the base frame, and the bottom end of the sliding seat abuts against the top of the support beams.

[0008] Preferably, the base frame is symmetrically provided with four sets of sliding holes, and each of the four sets of sliding holes is provided with a T-shaped guide post, the top of each of the four sets of T-shaped guide posts being fixedly connected to the bottom of the testing platform.

[0009] Preferably, four sets of buffer pads are symmetrically fixedly connected to both sides of the top of the base frame.

[0010] Preferably, each of the two sets of sliding seats is symmetrically provided with two sets of guide holes, and a sliding sleeve is fixedly provided in the guide hole. The sliding sleeve is slidably fitted onto the corresponding guide rod.

[0011] Compared with existing technologies, the advantages of this invention are as follows: During use, operators can adjust the height of the testing platform according to their own height. During adjustment, the dual-axis motor is activated, driving the transmission screw to rotate. When the transmission screw rotates clockwise, it drives the sliding seat to slide outward along the guide rod, causing the sliding seat to push the testing platform upward via the support plate, thus raising the platform height. When the transmission screw rotates counterclockwise, the testing platform height decreases. This allows the testing platform height to be adjusted to a position suitable for the operator's height before subsequent testing work, providing convenience for the operator. After testing, the testing platform height can be lowered to its lowest point, allowing the connecting seat to sink into the storage slot, enabling the testing platform to be placed on the base frame.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0018] Example

[0019] Please see Figures 1-4 This utility model discloses a high-precision petroleum hydrocarbon detection system, comprising a detection platform 1, a fixed base 2 at the top of the detection platform 1, a first extraction device 3, a second extraction device 4, and a separation device 5 inside the fixed base 2, a dual-axis motor 7 fixedly mounted on the top inner side of a base frame 6, and transmission screws 8 fixedly connected to the output ends on both sides of the dual-axis motor 7. The two sets of transmission screws 8 are symmetrically mounted on the base frame 6, and the threads on the two sets of transmission screws 8 have opposite directions. Two sets of guide rods are fixedly connected to the inner side of the base frame 6. 9. Two sets of sliding seats 10 are slidably mounted on the two sets of guide rods 9. The two sets of sliding seats 10 are screwed onto the corresponding transmission screws 8. Support plates 11 are rotatably connected to the front and rear ends of the two sets of sliding seats 10. Four sets of clearance grooves 13 are symmetrically opened at the top of the base frame 6. Each of the four sets of clearance grooves 13 has a storage groove 14 on its outer side. The support plates 11 pass through the clearance grooves 13. Four sets of connecting seats 12 are symmetrically fixed on both sides of the bottom of the testing table 1. The upper part of the support plates 11 is rotatably connected to the connecting seats 12. During use, the operator can adjust the height of the testing table 1 according to their own height.

[0020] Two sets of support beams 15 are symmetrically fixed to the inner side of the base frame 6, and the bottom end of the sliding seat 10 abuts against the top of the support beams 15. By setting the support beams 15, the support beams 15 provide further support to the sliding seat 10, ensuring that the sliding seat 10 will not bend the guide rod 9 during movement, thus improving stability.

[0021] The base frame 6 is symmetrically provided with four sets of sliding holes, and T-shaped guide posts 16 are slidably provided on each of the four sets of sliding holes. The top of the four sets of T-shaped guide posts 16 is fixedly connected to the bottom of the testing table 1. By setting the T-shaped guide posts 16, when the support plate 11 pushes the testing table 1 to move, the testing table 1 drives the T-shaped guide posts 16 to slide. Through the guidance of the T-shaped guide posts 16, the movement of the testing table 1 during the height adjustment process is more stable and reliable.

[0022] Four sets of buffer pads 17 are symmetrically fixed on both sides of the top of the base frame 6. By setting the buffer pads 17, the test table 1 is prevented from directly colliding with the top of the base frame 6 when it is placed on the base frame 6, thus playing a buffering role.

[0023] Two sets of guide holes are symmetrically provided on each of the two sets of sliding seats 10. A sliding sleeve 18 is fixedly installed in the guide hole. The two sets of sliding seats 10 are slidably fitted onto the two sets of guide rods 9 through the cooperation of the sliding sleeve 18. By setting the sliding sleeve 18, the sliding seat 10 slides more smoothly on the guide rod 9.

[0024] The working principle of this utility model is as follows: In use, the dual-axis motor 7 is started, causing the transmission screw 8 to rotate. When the transmission screw 8 rotates clockwise, it drives the sliding seat 10 to slide outward along the guide rod 9, causing the sliding seat 10 to push the testing platform 1 upward via the support plate 11, thus raising the height of the testing platform 1. When the transmission screw 8 rotates counterclockwise, the height of the testing platform 1 decreases, allowing the height of the testing platform 1 to be adjusted to a position suitable for the worker's height, facilitating the testing work before proceeding with subsequent testing. After testing, the height of the testing platform 1 can be lowered to its lowest point, at which point the connecting seat 12 can sink into the storage slot 14, and the testing platform 1 can be placed on the base frame 6.

[0025] The installation, connection, or setting methods of this utility model are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. The dual-axis motor 7 used in this utility model is purchased from the market, and technicians in this industry only need to install and operate it according to the accompanying instruction manual.

[0026] Furthermore, the detection platform 1, the fixed base 2, the first extraction device 3, the second extraction device 4, and the separation device 5 in this utility model are all referenced from a multi-stage extraction detection device for total petroleum hydrocarbons in soil disclosed in patent publication number CN114487222B. These are existing technologies that have already been disclosed. The specific structure and working principle during detection have been described in detail in that patent, so this application will not elaborate further.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
