Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0028] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] See Figure 1 , Figure 1 A lid-lifting sampling device is shown, comprising: a connecting seat 1 disposed on the top cover of a storage tank; a sampling cover 2 disposed on the connecting seat 1; and a support seat 3 disposed beside the connecting seat 1, wherein a pull rope 34 connected to the sampling cover 2 is disposed on the support seat 3; wherein the sampling cover 2 is connected to a rotating shaft 35 disposed on the support seat 3, so that the sampling cover 2 rotates around the rotating shaft 35 under the pull of the pull rope 34.

[0030] In some embodiments, by providing a connecting seat 1 on the top cover of the storage tank and placing the sampling cover 2 on the connecting seat 1, the sampling port is covered. The sampling cover 2 is pulled by a support seat 3 provided on the side of the connecting seat 1. Specifically, the rotating shaft 35 provided on the support seat 3 is connected to the sampling cover 2. The sampling cover 2 is pulled by the pull rope 34 on the support seat 3, causing the sampling cover 2 to rotate around the rotating shaft 35, thereby opening the sampling cover 2. Since the rotating shaft 35 is far away from the sampling port, the volatile oil and gas will not adhere to the rotating shaft 35, thus solving the technical problem of the sampling cover 2 being difficult to rotate.

[0031] See Figure 2 and Figure 3 In some embodiments, the sampling cover 2 includes a cover body 21 and a connecting rod 22. The connecting rod 22 includes a horizontally arranged straight rod 221 and an inclined rod 222. The inclined rod 222 is connected to a rotating shaft 35, which is inserted into a bearing seat 36. Thus, when the pull rope 34 pulls the sampling cover 2, the cover body 21 rotates around the rotating shaft 35 via the inclined rod 222 of the connecting rod 22, thereby opening the cover body 21 by pulling it open.

[0032] In some embodiments, the sampling cover 2 further includes a connecting cover 24 disposed on the top surface of the straight rod 221. The connecting cover 24 is provided with a first pulley 23. The first pulley 23 reduces the lifting force required when the pull rope 34 pulls the connecting cover 24. Specifically, the support base 3 is provided with a pull ring 32 and a second pulley 33 respectively. The pull ring 32 is located below the second pulley 33. By fixing one end of the pull rope 34 to the pull ring 32 and passing the other end around the first pulley 23 and the second pulley 33 in sequence, it is connected to a driving member (not shown in the figure). Under the driving action of the driving member, the pull rope 34 is pulled up, thereby lifting the connecting cover 24. The connecting cover 24 is connected to the cover body 21 through the straight rod 221, thereby lifting the cover body 21 and realizing the opening of the cover.

[0033] In some embodiments, in related technologies, the lifting method typically involves one end of a pull rope fixedly connected to the sampling cover, while the other end is manually pulled by the operator to lift the cover. This requires considerable pulling force and is difficult to operate. The first pulley 23 and the second pulley 33, when the sampling cover is lifted, require less effort due to the pulley system. Simultaneously, by increasing the height of the column 31, the pulling arm is lengthened. This combined design can save up to 60% of the force required to lift the sampling cover, meaning only 40% of the original force is needed.

[0034] In some embodiments, a notch adapted to the width of the column is provided on the side wall of the connecting cover 24, so that the column 31 is avoided after the connecting cover 24 is rotated, allowing the connecting cover 24 to open at a larger angle.

[0035] In some embodiments, the connecting seat 1 is arranged in the form of an inverted trapezoid; wherein the diameter of the bottom opening of the connecting seat 1 is adapted to the diameter of the sampling port opened on the top cover, and the diameter of the top opening of the connecting seat 1 is adapted to the diameter of the cover body 21, so that the cover body 21 can completely cover the sampling port.

[0036] Secondly, this disclosure also provides a lid-lifting sampling device, which includes: a connecting seat 1, disposed on the top cover of a storage tank; a sampling cover 2 disposed on the connecting seat 1; and a support seat 3 disposed beside the connecting seat 1, wherein a pull rope 34 connected to the sampling cover 2 is disposed on the support seat 3; wherein a first pulley 23 is disposed on the connecting cover 24 of the sampling cover 2, and a pull ring 32 and a second pulley 33 are disposed on the column of the support seat 3; the pull ring 32 is located below the second pulley 33; one end of the pull rope 34 is connected to the pull ring 32, and the other end passes through the first pulley 23 and then through the second pulley 33; a driving member connected to the pull rope 34 is disposed on the column, and the driving member pulls the pull rope 34 to move, thereby driving the sampling cover 2 to rotate.

[0037] In summary, this flip-top sampling device covers the sampling port by setting a connecting seat 1 on the top cover of the storage tank and placing the sampling cover 2 on the connecting seat 1. The sampling cover 2 is pulled by a support seat 3 set on the side of the connecting seat 1. Specifically, the rotating shaft 35 set on the support seat 3 is connected to the sampling cover 2. The sampling cover 2 is pulled by the pull rope 34 on the support seat 3, so that the sampling cover 2 rotates around the rotating shaft 35, thus opening the sampling cover 2. Since the rotating shaft 35 is far away from the sampling port, the volatile oil and gas will not adhere to the rotating shaft 35, thereby avoiding the rotation of the sampling cover 2 being obstructed by the oil and gas adhering to the rotating shaft 35, and solving the technical problem of the sampling cover 2 being difficult to rotate.

[0038] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.

In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0046] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
