[0001] This utility model relates to the field of sampling device technology, specifically a sampling device for monitoring total hydrocarbon concentration at the inlet of an oil and gas treatment environmental protection system. Background Technology

[0002] The core function of the total hydrocarbon concentration monitoring and sampling device at the inlet of the oil and gas treatment environmental protection system is to accurately and in real time grasp the initial concentration of pollutants before treatment, providing key data support for the performance evaluation of subsequent treatment processes, emission compliance verification and system operation optimization. Therefore, the total hydrocarbon concentration monitoring and sampling device at the inlet of the oil and gas treatment environmental protection system is required.

[0003] Although existing technologies for monitoring and sampling devices for total hydrocarbon concentration at the inlet of oil and gas treatment environmental protection systems have many beneficial effects, the following problems still exist: after the device extracts the gas, the inlet of the extraction device is mostly still directly exposed to the outside, which makes it easy for the extracted gas inside the extraction device to come into contact with the external environment, thus easily affecting the stability of the gas in the tank.

[0023] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] This utility model provides an overall structural schematic diagram of an embodiment of a total hydrocarbon concentration monitoring and sampling device for the inlet of an oil and gas treatment environmental protection system, including: Please see Figure 1 - Figure 6 This utility model provides a technical solution: See also Figure 1 Figure 6 As shown, the total hydrocarbon concentration monitoring and sampling device at the inlet of the oil and gas treatment environmental protection system includes a housing 1 and an inlet 51 opened at the bottom of the housing 1, a clamping plate 57 connected to the inner wall of the inlet 51 by a bearing; a sealing assembly 5 installed on the inner wall of the inlet 51 for driving the clamping plate 57 to rotate; and a driving assembly 4 installed inside the housing 1 for driving the sealing assembly 5 to move, thereby facilitating the sealing effect of the housing 1.

[0025] See also Figure 2 Figure 5 As shown, the drive assembly 4 includes a drive rod 41, a track 42 is sleeved on the outer circumference of the drive rod 41, and an auxiliary rod 43 is sleeved on the inner wall of the track 42. The track 42 drives the auxiliary rod 43 to rotate, so that the auxiliary rod 43 and the drive rod 41 can move synchronously, thereby changing the position of the clamping plate 57 while the suction plate 2 is raised and lowered.

[0026] See also Figure 2 Figure 4 As shown, a gear 44 is inserted into the bottom of the auxiliary rod 43. A gear ring 45 is meshed with the outer circumference of the gear 44. A gear 46 is meshed with the inner circumference of the gear ring 45. A vertical rod 54 is sleeved on the inner circumference of the gear 46. By utilizing the meshing connection between the gear 44, the gear 46 and the gear ring 45, the gear 46 can synchronously drive the vertical rod 54 to rotate while the gear 44 rotates in conjunction with the auxiliary rod 43, thereby achieving the purpose of driving the slider 53 to rise and fall.

[0027] See also Figure 3 and Figure 4As shown, there are multiple gears 46, which are arranged in a ring shape. The multiple gears 46 allow the clamping plate 57 to close at multiple angles to the inner wall of the feed port 51.

[0028] See also Figure 3 As shown, a slider 53 is slidably connected to the outer circumference of the vertical rod 54. One end of the slider 53 is connected to a support bar 55 through a bearing. The vertical rod 54 rotates to drive the slider 53 to rise and fall, so that the support bar 55 can drive the clamping plate 57 to change, thereby achieving the purpose of changing the position of the clamping plate 57.

[0029] See also Figure 3 As shown, a slot 56 is provided at the bottom of the card plate 57. A support strip 55 is slidably connected to the inner wall of the slot 56. By using the support strip 55 to slidably connect to the slot 56, the support strip 55, the card plate 57 and the vertical rod 54 are directly in a triangular state, which makes it easier to maintain the stability of the card plate 57 in various positions.

[0030] See also Figure 3 As shown, a groove 52 is provided on the inner wall of the feed inlet 51. The surface of the slider 53 is slidably connected to the groove 52. By using the slider 53 to slide on the inner wall of the groove 52, the support bar 55 can change its angle by rising and falling along the position of the slider 53, thereby driving the card plate 57 to change its angle position.

[0031] See also Figure 3 As shown, a sealing strip 58 is embedded on the surface of the card plate 57, which enhances the sealing effect when the card plate 57 is closed.

[0032] See also Figure 4 and Figure 5 As shown, a limiting groove 61 is provided at the bottom of the housing 1. A limiting pin 6 is threadedly connected to the inner wall of the limiting groove 61. The outer circumferential wall of the limiting pin 6 is inserted into the circumferential surface of the gear 44. By using the limiting pin 6 to insert into the surface of the gear 44, the position of the clamping plate 57 is kept stationary when the operator needs to extract a large amount of oil and gas, which is beneficial to adjust the extraction needs according to the actual situation.

[0033] See also Figure 2 As shown, an air extraction plate 2 is slidably connected to the outer circumference of the vertical rod 54, and a filter plate 3 is bolted to the inner wall of the housing 1. The filter plate 3 filters and isolates the moisture in the air, thereby maintaining the purity of the extracted oil and gas.

[0034] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0035] Combination Figure 1- Figure 6 The specific usage process of the total hydrocarbon concentration monitoring and sampling device at the inlet of an oil and gas treatment environmental protection system according to this embodiment is as follows: 1. In actual use, the staff moves the box 1 to a suitable position, and the drive motor makes the drive rod 41 rotate, so that the suction plate 2 can rise to extract the required oil and gas. At the same time, the track 42 rotates synchronously with the drive rod 41, so that the auxiliary rod 43 drives the gear 1 44 to mesh with the gear ring 45, so that the gear 2 46 synchronously drives the vertical rod 54 to rotate. Thus, the slider 53 can rise along the outer circumference of the vertical rod 54 on the inner wall of the slide groove 52. Therefore, the support bar 55 can synchronously slide and connect to the inner wall of the slot 56, and the inner wall pivot point of the feed port 51 drives the clamping plate 57 to change the angle. Thus, after the air is extracted, the feed port is also closed and blocked by the clamping plate 57. In conjunction with the sealing strip 58, the sealing effect of the gas extracted inside the box 1 is maintained, reducing the interference of the external environment and maintaining the integrity of the sampled gas. 2. When the volume of gas to be extracted by the staff is large, the limiting pin 6 is threaded into the limiting groove 61, so that the outer circumference of the limiting pin 6 can be inserted into the surface of the gear 44, thereby stopping the gear 44 from rotating, that is, fixing the position and angle of the clamping plate 57, so that the suction plate 2 continues to rise to achieve the purpose of suction.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
