[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments and features of this utility model can be combined with each other.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0020] The following is combined with Figs. 1 to 3 The specific embodiments of this utility model will be described in detail below.

[0021] This embodiment provides an adjustable high-altitude viewing device, including a connecting component 1, a telescopic cylinder component 2, a reflective component, and a lifting component 3.

[0022] The connecting component 1 is used to fix it to the container under test 100.

[0023] As is easily understood, the connecting component 1 is a structure used to fix the device onto the container 100 to be tested, and its specific design can be adapted to the shape and size of the container 100 to be tested. For example, in this embodiment, which is for a metering tanker, the connecting component 1 includes a lower connecting ring 11, an upper connecting ring 12, and a connecting vertical plate 13; the lower connecting ring 11 is used to be loosely fitted onto the bottom end of the container 100 to be tested; the upper connecting ring 12 is used to be loosely fitted onto the container 100 to be tested and is located above the lower connecting ring 11; the top end of the connecting vertical plate 13 is provided with a first waist wheel 14 and the bottom end is provided with a second waist wheel 15. The first waist wheel 14 is snapped below the upper connecting ring 12, and the second waist wheel 15 is snapped above the lower connecting ring 11. The connecting vertical plate 13 is fixedly connected to the fixing cylinder 21. In this embodiment, the connecting component 1 can be well adapted to the metering tank truck, and the connecting vertical plate 13 can be moved circumferentially through the first waist wheel 14 and the second waist wheel 15. For the metering tank truck, which is prone to uneven liquid surface, the metering accuracy is higher by measuring at multiple positions in the circumferential direction and then calculating the average value.

[0024] It is easy to understand that the upper connecting ring 12 and the lower connecting ring 11 are fitted onto the container 100 under test with a gap. The purpose is to provide space for the installation of the lap wheel. Specifically, the connecting ring and the container 100 under test can be fitted together by welding, bolts or magnetic attraction.

[0025] Specifically, in this embodiment, a horizontally arranged arc-shaped strip 16 is fixed to the bottom end of the connecting vertical plate 13, and a second waist wheel 15 is installed at each end of the arc-shaped strip 16. The two second waist wheels 15 located at the bottom are more conducive to maintaining the stability of the connecting vertical plate 13 on the connecting ring.

[0026] Furthermore, in this embodiment, multiple positioning grooves 111 are distributed circumferentially at intervals on the lower surface of the lower connecting ring 11, and a buckling assembly 4 is provided at the bottom end of the connecting vertical plate 13. The buckling assembly 4 has a positioning state of being engaged in the positioning groove 111 and a clearance state of being disengaged from the positioning groove 111. Since the metering tanker has a display window at a fixed position in the circumference, the positioning groove 111 is set at the position corresponding to the display window. This allows the connecting vertical plate 13 to be limited by the cooperation between the buckling assembly 4 and the positioning groove 111 when it moves to the position of the positioning groove 111, which is more conducive to reading the reading smoothly and accurately.

[0027] Specifically, the buckle assembly 4 in this embodiment includes a swing rod 41, a telescopic rod 43, and a compression spring 44; one end of the swing rod 41 is rotatably mounted on the connecting vertical plate 13 with its rotation axis arranged horizontally, and the other end is equipped with a positioning wheel 42; one end of the telescopic rod 43 is rotatably mounted on the connecting vertical plate 13 with its rotation axis arranged horizontally; the compression spring 44 is sleeved on the telescopic rod 43, and when the compression spring 44 abuts against the swing rod 41, the positioning wheel 42 is engaged in the positioning groove 111 to keep the buckle assembly 4 in the positioning state, and when the compression spring 44 disengages from the swing rod 41, the positioning wheel 42 disengages from the positioning groove 111 to switch the buckle assembly 4 to the avoidance state. When a limiting position is required, the compression spring 44 is manually compressed, and the telescopic rod 43 is adjusted so that the compression spring 44 abuts against the lower part of the swing rod 41. The positioning wheel 42 is engaged in the positioning groove 111 and held in the positioning groove 111 by the elastic force of the compression spring 44, thus limiting the connection vertical plate 13 at that circumferential position. When an avoidance position is required, the compression spring 44 is manually compressed, and the telescopic rod 43 is adjusted to disengage from the swing rod 41, so that the buckle assembly 4 switches to the avoidance state. This structure is relatively convenient to operate and the positioning effect is relatively reliable.

[0028] The telescopic cylinder assembly 2 includes a fixed cylinder 21 and a movable cylinder 22. The fixed cylinder 21 is fixedly connected to the connecting assembly 1 and arranged vertically. The movable cylinder 22 is slidably sleeved on the fixed cylinder 21. The top of the movable cylinder 22 extends horizontally towards the container 100 to be tested, and a first horizontal cylinder 23 extends horizontally. The free end of the first horizontal cylinder 23 forms a collection window 24. The bottom of the fixed cylinder 21 extends horizontally away from the container 100 to be tested, and a second horizontal cylinder 25 extends horizontally. The free end of the second horizontal cylinder 25 forms a reading window 26. The first horizontal cylinder 23, the movable cylinder 22, the fixed cylinder 21, and the second horizontal cylinder 25 together form an optical channel.

[0029] Specifically, in this embodiment, both the fixed cylinder 21 and the movable cylinder 22 are square cylinders, and the movable cylinder 22 is fitted inside the fixed cylinder 21. The square cylinder can not only achieve vertical guidance, but also avoid horizontal rotation and twisting; the movable cylinder 22 is placed inside the fixed cylinder 21, which can avoid interference with the connection between the fixed cylinder 21 and the connecting component 1.

[0030] The reflective component is used to reflect the light entering from the acquisition window 24 to the reading window 26. The reflective component includes at least two mirrors arranged in the optical channel.

[0031] Specifically, this embodiment has two reflectors located at the two corners of the optical channel, and the reflectors are arranged at a 45° angle. One reflector can deflect the direction of light by 90°, and the two reflectors work together to make the light eventually parallel to the original light, with only a vertical translation, so that the operator can view the field of view of the acquisition window 24 from the reading window 26 below.

[0032] As is easily understood, the two corners of the optical channel are located at the junction of the first horizontal cylinder 23 and the movable cylinder 22, and at the junction of the second horizontal cylinder 25 and the fixed cylinder 21, respectively.

[0033] It should be noted that two reflectors are sufficient, but more reflectors can be set to deflect the light more than twice, as long as the light can eventually exit from the reading window 26.

[0034] The lifting assembly 3 includes a fixed part and a lifting part. The fixed part is connected to the fixed cylinder 21, and the lifting part is connected to the movable cylinder 22.

[0035] Specifically, the fixing part in this embodiment includes a mounting cylinder 31, a gear 32, and a handwheel 33. The mounting cylinder 31 is vertically arranged and fixedly connected to the fixing cylinder 21. The gear 32 is rotatably mounted on the bottom of the mounting cylinder 31 and integrally connected to the handwheel 33. The lifting part includes a rack 34, which is fixedly connected to the movable cylinder 22. The rack 34 is inserted into the mounting cylinder 31 and meshes with the gear 32. In use, the operator rotates the handwheel 33 to drive the gear 32 to rotate, thereby driving the rack 34 to rise and fall, thus realizing the raising and lowering of the movable cylinder 22.

[0036] It should be noted that the lifting component 3 in this embodiment is designed to be manual, while electric or other automatic structures may be used in other embodiments.

[0037] The working principle of the adjustable high-altitude observation device in this embodiment is as follows: In use, first install the first waist wheel 14 and the second waist wheel 15 on the corresponding connecting rings, then fix the upper connecting ring 12 and the lower connecting ring 11 on the container to be tested 100. Adjust the acquisition window 24 to a suitable height by rotating the handwheel 33, and then move the acquisition window 24 to the target acquisition position by circumferential movement. The operator reads the reading at the target acquisition position through the reading window 26. Repeat the operation to read the readings at multiple positions in the circumferential direction. Finally, calculate the average value to get the final reading.

[0038] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and all should be covered by the protection scope of the claims.
