[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-6 The present invention discloses a boiler endoscope observation auxiliary device, including an endoscope component 1, which includes a rod body 101, a lens component 102 installed at one end of the rod body 101, and a wire 103 passing through the rod body 101, wherein one end of the wire 103 is connected to the lens component 102 for signal connection, and the other end thereof can be connected to an external terminal signal. It can extend into the boiler from the observation hole to observe the interior of the boiler. The endoscope component 1 is common knowledge in the field, so the specific working principle thereof will not be described in detail in this article.

[0016] In one embodiment, an adjustment component 2 is provided on the endoscope component 1, and the adjustment component 2 has a mounting end and a sliding end, and the sliding end can be slidably mounted on the endoscope component 1. The device also includes at least three folding components 3 and positioning components 4, wherein the two ends of the folding component 3 are respectively hingedly provided at the mounting end and the sliding end of the adjustment component 2. When the sliding end of the adjustment component 2 slides on the endoscope component 1, it can drive each folding component 3 to fold or unfold in an umbrella shape; and each positioning component 4 is respectively provided on the corresponding folding component 3. After the folding component 3 is folded, the positioning component 4 can be moved to the side away from the endoscope component 1.

[0017] In the specific implementation, in the initial state, the folding component 3 is in the folded state. When in use, the endoscope component 1 is first inserted into the observation hole. When it is inserted until each positioning component 4 is aligned with the inner wall of the boiler, the adjustment component 2 can be operated to make each folding component 3 move and fold. At this time, it will cause each positioning component 4 to move to the side away from the endoscope component 1, that is, to move to the side close to the side wall of the observation hole. When it moves until each positioning component 4 is docked with the side wall of the observation hole, the endoscope component 1 can be fixed very stably at the center of the observation hole, so that the staff can operate the endoscope component 1 to observe the inside of the boiler very conveniently, labor-saving and accurately.

[0018] At the same time, the endoscope component 1 and the adjustment component 2 can be connected in a rotating manner and used in conjunction with a corresponding fixing device, which can be a clamp. When the positioning component 4 is fixed to the side wall of the observation hole, the endoscope component 1 can be rotated to change its observation angle. After the angle adjustment is completed, the clamp is closed to clamp the endoscope component 1 for positioning, thereby facilitating observation of different positions inside the boiler. The clamp mentioned above is common knowledge in this field, and its specific structure will not be described in detail in this article.

[0019] In one embodiment, the adjustment component 2 includes a first mounting sleeve 201 and a second mounting sleeve 202 relatively mounted on the rod body 101, and a sliding sleeve 204 is slidably mounted on the rod body 101 and located between the first mounting sleeve 201 and the second mounting sleeve 202. At least two connecting shafts 203 are installed between the first mounting sleeve 201 and the second mounting sleeve 202, and one of the connecting shafts 203 is a lead screw, which can rotate clockwise or counterclockwise. The sliding sleeve 204 is threadedly engaged with the connecting shaft 203 which is a lead screw and is sleeved with the other connecting shafts 203, and an adapter 205 is provided on the lead screw, and the two ends of the folding component 3 are respectively hingedly mounted on the first mounting sleeve 201 and the sliding sleeve 204.

[0020] In the specific implementation, the staff can rotate the connecting shaft 203 which is a screw to move the sliding sleeve 204 threadedly connected to it to the side close to or away from the first mounting sleeve 201, thereby folding or unfolding the folding component 3. When it is folded, the positioning component 4 can be close to the inner wall of the observation hole, thereby facilitating subsequent positioning and fixation; when it is unfolded, the positioning component 4 can be close to the center of the endoscope component 1 to facilitate subsequent recycling and processing.

[0021] In addition, the corresponding tool can be plugged into the adapter 205 to facilitate the rotation adjustment of the corresponding connecting shaft 203. The tool can be a manual tool such as a wrench, or an electric tool such as a motor. This type of tool is common knowledge in the field, so the specific structural composition and working principle will not be described in detail in this article.

[0022] In one embodiment, the folding assembly 3 includes a first connecting rod 301 and a second connecting rod 302 respectively hingedly mounted on the first mounting sleeve 201 and the sliding sleeve 204, the first connecting rod 301 and the second connecting rod 302 are hingedly matched on one side close to each other, and the positioning assembly 4 is arranged at the hinged connection between the first connecting rod 301 and the second connecting rod 302.

[0023] With this design, when the sliding sleeve 204 moves toward the side close to the first mounting sleeve 201, the first connecting rod 301 and the second connecting rod 302 will be folded in a V shape, thereby causing the positioning assembly 4 located between the first connecting rod 301 and the second connecting rod 302 to move toward the side away from the endoscope assembly 1; when the sliding sleeve 204 moves toward the side away from the first mounting sleeve 201, the first connecting rod 301 and the second connecting rod 302 will be unfolded, and at this time the positioning assembly 4 moves toward the side close to the endoscope assembly 1.

[0024] In one embodiment, the positioning assembly 4 includes an abutment platform 401 rotatably mounted at the hinged connection between the first connecting rod 301 and the second connecting rod 302, an abutment plate 402 is mounted on the abutment platform 401, and the abutment platform 401 and the abutment plate 402 are L-shaped. A positioning hook 403 is rotatably mounted on the side of the abutment platform 401 away from the abutment plate 402, and a vertical slide groove 404 is provided inside the abutment platform 401, an abutment bar 405 is slidably mounted in the slide groove 404, and a spring (not shown in the figure) for squeezing the abutment bar 405 to reset it is also installed in the slide groove 404, a rack 406 is installed on the abutment bar 405 along its length, and a gear 407 meshing with the rack 406 is rotatably provided on the abutment platform 401, and the gear 407 is coaxially mounted with the positioning hook 403.

[0025] In a specific implementation, after the endoscope component 1 is inserted into the observation hole, and the abutment plate 402 is located inside the boiler and the positioning hook 403 is located outside the boiler, the folding component 3 can be adjusted to fold it. At this time, the abutment platform 401 will move to the side close to the side wall of the observation hole, and then the position can be adjusted so that the abutment plate 402 contacts the inner wall of the boiler and the abutment platform 401 contacts the side wall of the observation hole. During this movement, the side wall of the observation hole will contact the abutment bar 405. At this time, the abutment bar 405 will slide to the side away from the abutment plate 402. At this time, the gear The bar 406 moves synchronously and drives the gear 407 to rotate, and the positioning hook 403 coaxially matched with the gear 407 will rotate toward the side close to the abutment plate 402, and the positioning hook 403 will abut against the outer wall of the boiler. Therefore, the abutment plate 402, the abutment platform 401 and the positioning hook 403 will further make the endoscope assembly 1 more stable and safe when fixed at the center of the observation hole; when the abutment platform 401 moves to the side away from the side wall of the observation hole, the abutment bar 405 releases the limited abutment state, and at this time the spring will squeeze the abutment bar 405 to reset it.

[0026] In addition, the side of the abutting plate 402 in contact with the boiler has a rounded corner, so it can adapt to the curved inner wall of the boiler and effectively abut against it.

[0027] In one embodiment, a ratchet component is provided at the coaxial connection between the gear 407 and the positioning hook 403. In the specific implementation, the ratchet component can be adjusted to an abutment state or an unlocked state. When it is in the abutment state, the positioning hook 403 can only rotate to the side close to the abutment plate 402, thereby ensuring that the positioning hook 403 is difficult to rotate, thereby effectively ensuring its abutment stability against the outer wall of the boiler; when the staff manually unlocks the ratchet component and puts the ratchet component in the unlocked state, the positioning hook 403 can be rotated to the side away from the abutment plate 402 to facilitate its subsequent removal from the observation hole.

[0028] In one embodiment, the ratchet component includes a ratchet 408 installed at the coaxial connection between the gear 407 and the positioning hook 403 , and a pawl 409 in contact with the ratchet 408 is rotatably installed on the abutment platform 401 .

[0029] In a specific implementation, a torsion spring (not shown in the figure) is provided at the rotational connection between the pawl 409 and the abutment platform 401. The torsion spring is used to ensure that the pawl 409 always contacts the ratchet 408 under normal conditions. When manual unlocking is required, the staff can manually rotate the pawl 409 to the side away from the ratchet 408.

[0030] In one embodiment, the device also includes a guide assembly 5 arranged on the folding assembly 3, and the guide assembly 5 includes a third connecting rod 501 and a fourth connecting rod 502 respectively hingedly mounted on the first connecting rod 301 and the second connecting rod 302, and the opposite sides of the third connecting rod 501 and the fourth connecting rod 502 are hingedly matched, and they are combined in a diamond shape with the first connecting rod 301 and the second connecting rod 302, and a supporting platform 503 is rotatably mounted at the hinged connection between the third connecting rod 501 and the fourth connecting rod 502, and a telescopic rod 504 is mounted on the supporting platform 503. In addition, a through hole is opened on the abutment platform 401, and the telescopic rod 504 extends into the through hole away from the side of the supporting platform 503.

[0031] In a specific implementation, when the first connecting rod 301 and the second connecting rod 302 are folded or unfolded, the third connecting rod 501 and the fourth connecting rod 502 will also be folded or unfolded. During this process, the supporting platform 503 and the telescopic rod 504 can always be oriented toward the hinge of the first connecting rod 301 and the second connecting rod 302, and the telescopic rod 504 is inserted into the through hole, thereby ensuring that the abutment platform 401 always maintains an unchanged angle when the first connecting rod 301 and the second connecting rod 302 are rotated and adjusted, so as to facilitate subsequent fixed cooperation with the side wall of the observation hole.

[0032] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features.
