Referring to fig. 6, in an embodiment, the number of the lighting lamps 220 is multiple, and the lighting lamps 220 are spaced around the outer periphery of the camera 212. Because different light 220 sets up around camera 212, and then can provide more stable illumination for camera 212 gathers the image, improve image acquisition's quality. In another embodiment, the illumination lamp 220 is a ring lamp, and the camera 212 is disposed within an inner ring of the ring lamp. Of course, in other embodiments, the illumination lamp 220 may be spaced apart from and juxtaposed to the camera 212.

Referring to fig. 1, 3 and 10, in an embodiment, the wireline well observation device 10 further includes a placing bracket 300, the placing bracket 300 is rotatably disposed on an outer wall of the observation cylinder 130 and is located near the eyepiece 110, and the placing bracket 300 is used for placing a display device. Can place display device during the use to place on the support 300, be convenient for display device and camera 212 be connected, and then the image transmission to display device that the camera 212 of being convenient for gathered. In this embodiment, the display device may be a mobile phone, and in other embodiments, the display device may also be a computer, a display, and the like. And since the placing bracket 300 is rotatable with respect to the observation tube 130, it is convenient to adjust the position of the placing bracket 300.

Specifically, the placing support 300 is formed with a placing platform 310, and the placing platform 310 can rotate towards or away from the outer wall of the observation cylinder 130. In use, the placing platform 310 can be rotated away from the observation tube 130, so that the placing platform 310 is arranged upward, and the display device can be placed on the placing platform 310 conveniently. After use, the placing platform 310 can be rotated toward the outer wall of the observation tube 130, so that the placing bracket 300 can be received on the outer wall of the observation tube 130.

Further, the placing platform 310 and the observation tube 130 can be turned over within the range of 0-90 degrees, so that the storage is convenient, and meanwhile, the placing angle of the display device is convenient to adjust.

Referring to fig. 1, in one embodiment, a handle 400 is further disposed on an outer wall of the observation tube 130, and the handle 400 is located near the eyepiece 110. The wireline well observation device 10 is facilitated to be held and operated by the handle 400. Specifically, the handle 400 can be rotated toward or away from the outer wall of the observation tube 130. When the observation tube 130 is used, the handle 400 is rotated in a direction away from the outer wall of the observation tube 130, so that the use is facilitated, and after the use is completed, the handle 400 is rotated in a direction toward the outer wall of the observation tube 130, so that the handle 400 is stored conveniently.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
