Description

Technical Field

[0001] This utility model belongs to the technical field of power system monitoring equipment, specifically referring to a sealing device for a detection camera to check the status of GIS equipment. Background Technology

[0002] Currently, the fault tolerance rate of GIS room equipment in power systems is low, and a failure can have serious consequences. Furthermore, GIS equipment is not yet mature enough to directly monitor its actual status. To prevent misoperation, ensure equipment safety, and guarantee the normal operation of the opening and closing of disconnectors and grounding switches in the GIS room of UHV converter stations, using an endoscope to observe whether the opening and closing are in place is the most accurate and direct method. Therefore, to achieve remote online monitoring of GIS equipment status, an endoscopic camera is typically installed in the observation window of the GIS equipment. An LED supplementary lighting source is also needed to illuminate the endoscopic camera, enabling observation of the opening and closing operations inside the GIS equipment.

[0003] Existing camera sealing devices simply drill two parallel holes in the mounting base, one for fixing the camera and the other for fixing the LED supplementary light source. Because the two are set in parallel, the brightness at the camera is greater than the brightness at the subject, which is extremely detrimental to camera shooting.

[0004] Furthermore, existing camera sealing devices are typically fixed directly to the camera before being installed on the observation window, with the camera's shooting angle determined by the sealing device. Since GIS equipment is filled with high-pressure sulfur hexafluoride insulating gas, the camera's sealing device must be installed on the observation window beforehand. Only after the sealing device is installed can the high-pressure sulfur hexafluoride insulating gas be introduced into the GIS equipment. Due to light refraction and other factors, there will be some deviation when viewing the inside of the GIS equipment through the observation window. Therefore, experienced operators are needed to accurately determine the installation position of the sealing device to ensure the camera can accurately capture the opening and closing operations of the GIS indoor disconnect switches and grounding switches. Otherwise, the camera's shooting angle may be inaccurate, making it impossible to accurately capture the opening and closing operations of the GIS indoor disconnect switches and grounding switches, which is extremely detrimental to the inspection of the GIS equipment's condition. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device for a GIS equipment inspection camera that facilitates camera shooting and installation and ensures that the camera can accurately capture the range of the inspection.

[0006] This utility model is achieved through the following technical solution: a sealing device for a detection camera to check the status of GIS equipment, mainly installed on the observation window, including...

[0007] A connecting mechanism is fixedly installed on the observation window, and a through hole is provided inside it. The end of the connecting mechanism located outside the observation window is provided with an external thread.

[0008] A fixing mechanism is placed inside the observation window. The rear end of the fixing mechanism is detachably and fixedly connected to the front end of the connecting mechanism extending into the observation window. The fixing mechanism also has a through hole that communicates with the through hole in the connecting mechanism. A transparent plate is provided at the through hole at the front end of the fixing mechanism. An LED light strip is also installed around the transparent plate at the front end of the fixing mechanism. A ring-shaped light-blocking plate is also provided between the transparent plate and the LED light strip.

[0009] The observation window is a window used to observe the status inside the GIS equipment, and it is fitted with sealed plexiglass.

[0010] An endoscopic camera is fitted with an end cap. The endoscopic camera passes through the through holes in the connecting mechanism and the fixing mechanism in sequence and abuts against the transparent plate. The end cap is provided with internal threads and is threadedly connected to the connecting mechanism to fix the endoscopic camera in the connecting mechanism and the fixing mechanism.

[0011] The working principle of this technical solution is to optimize the position of the LED light strip and the camera in the fixing mechanism so that the endoscopic camera and the through hole of the fixing mechanism are coaxially set, and the LED light strip is set around the endoscopic camera. This makes the supplementary lighting range wider. In addition, the light-blocking plate can block the light emitted by the LED light strip and avoid adverse effects on the endoscopic camera's shooting.

[0012] By setting up a ring-shaped light-blocking plate, the adverse effects of LED lights as supplementary lighting on camera shooting are effectively avoided. This solves the problem of excessive brightness at the camera and insufficient illumination in the subject area caused by traditional parallel light sources, ensuring high-definition imaging.

[0013] To better realize this utility model, the front end of the fixing mechanism is further provided with a ball seat, and a rotatable ball head is installed in the ball seat. The ball head is provided with a through hole that matches the endoscopic camera. The transparent plate is set at the through hole at the front end of the ball head. The endoscopic camera passes through the through holes in the connecting mechanism and the fixing mechanism in sequence, and enters the through hole in the ball head to abut against the transparent plate.

[0014] To better realize this utility model, a spherical notch is further provided on the rear side of the ball head, and the axis of the through hole in the ball head coincides with the axis of the plane where the spherical notch is located.

[0015] To better realize this utility model, the ball seat at the front end of the fixing mechanism is a hemispherical cavity that matches the ball head.

[0016] To better realize this utility model, the LED light strip is further provided with a uniform light-diffusing lens to make the light source diffuse evenly.

[0017] To better realize this utility model, the power cord of the LED light strip passes through the through holes in the connecting mechanism and the fixing mechanism in sequence, and finally extends from the fitting point between the endoscopic camera and the end cover to connect with the external power source.

[0018] To better realize this utility model, the connecting mechanism is further threadedly connected to the observation window, and the connecting mechanism is threadedly connected to the fixing mechanism.

[0019] To better realize this utility model, an O-ring is further provided between the connecting mechanism and the observation window.

[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0021] (1) This utility model optimizes the position of the LED light strip and the camera in the fixing mechanism. By setting up a ring-shaped light blocking plate, it effectively avoids the adverse effects of LED light as a supplementary light source on the camera shooting. It solves the problem of excessive brightness at the camera and insufficient illumination in the subject area caused by traditional parallel light sources, and ensures high-definition imaging.

[0022] (2) The present invention uses a ball head and a ball seat at the front end of the fixing mechanism, so that the endoscope camera can be tilted and left and right after installation, and is fixed by sealant, which greatly increases the tolerance of the angle adjustment error, and does not need to rely on experience to predict the installation position, thus improving the installation efficiency of the sealing device.

[0023] (3) This utility model uses a double seal of threaded connection and O-ring to avoid leakage in the high pressure environment of sulfur hexafluoride. The connecting mechanism and the fixing mechanism adopt a detachable design. When replacing the camera, there is no need to disassemble the main body of the sealing device, which greatly improves the maintenance efficiency. In addition, the power cord is integrated into the through hole to avoid external line interference. It is stable and suitable for widespread application. Attached Figure Description

[0033] Example 1:

[0034] The main structure of this embodiment is as follows: Figure 1 As shown, it is mainly installed on the observation window 3, including

[0035] A connecting mechanism 1 is fixedly installed on the observation window 3, and has a through hole inside. The end of the connecting mechanism 1 located outside the observation window 3 is provided with an external thread.

[0036] A fixing mechanism 2 is placed inside the observation window 3. The rear end of the fixing mechanism 2 is detachably and fixedly connected to the front end of the connecting mechanism 1 that extends into the observation window 3. The fixing mechanism 2 also has a through hole that communicates with the through hole in the connecting mechanism 1. A transparent plate 21 is provided at the through hole at the front end of the fixing mechanism 2. An LED light strip 22 is also installed around the transparent plate 21 at the front end of the fixing mechanism 2. A ring-shaped light-blocking plate 23 is also provided between the transparent plate 21 and the LED light strip 22.

[0037] Observation window 3 is a window used to observe the status inside the GIS equipment, and it is fitted with sealed plexiglass.

[0038] An endoscopic camera 4 is fitted with an end cap 5. The endoscopic camera 4 passes through the through holes in the connecting mechanism 1 and the fixing mechanism 2 in sequence and abuts against the transparent plate 21. The end cap 5 is provided with an internal thread and is threadedly connected to the connecting mechanism 1 to fix the endoscopic camera 4 in the connecting mechanism 1 and the fixing mechanism 2.

[0039] The specific installation process is as follows: first, the fixing mechanism 2 is embedded in the front end of the connecting mechanism 1 to fix the two together, and the internal through holes are connected. Due to the setting of the transparent plate 21 at the front end of the fixing mechanism 2, the fixing mechanism 2 and the connecting mechanism 1 are kept sealed.

[0040] Next, the connecting mechanism 1 is installed on the observation window 3, so that the front fixing mechanism 3 is placed inside the observation window 3. Then, the endoscopic camera 4 is passed through the through holes in the connecting mechanism 1 and the fixing mechanism 2 in sequence, and abuts against the transparent plate 21. Then, sealant is filled into the through holes in the connecting mechanism 1 and the fixing mechanism 2 to reinforce the internal endoscopic camera 4. Finally, the end cap 5 is threadedly connected to the connecting mechanism 1 to fix the endoscopic camera 4 inside the connecting mechanism 1 and the fixing mechanism 2. Since the transparent plate 21 is a transparent structure, the endoscopic camera 4 can film the opening and closing operations of the GIS indoor switch and ground switch through the transparent plate 21.

[0041] When the endoscopic camera 4 captures the opening and closing operations of the GIS indoor switch and ground switch through the transparent plate 21, the LED light strip 22 surrounding the transparent plate 21 provides supplementary lighting for the opening and closing operations of the GIS indoor switch and ground switch, while the light-blocking plate 23 blocks the light from the LED light strip 22 towards the endoscopic camera 4, ensuring that the endoscopic camera 4 can achieve high-definition imaging.

[0042] Example 2:

[0043] This embodiment further defines the structure of the fixing mechanism 2 based on the above embodiment, such as... Figures 2-4As shown, the front end of the fixing mechanism 2 is also provided with a ball seat, and a rotatable ball head 26 is installed in the ball seat. The ball head 26 is provided with a through hole that matches the endoscopic camera 4. The transparent plate 21 is located at the through hole at the front end of the ball head 26. The endoscopic camera 4 passes through the through holes in the connecting mechanism 1 and the fixing mechanism 2 in sequence, and enters the through hole in the ball head 26, abutting against the transparent plate 21. The ball head 26 is added mainly so that when the endoscopic camera 4 is installed in the ball head 26, it can be adjusted slightly up, down, left, and right by rotating the ball head 26. This expands the field of view of the endoscopic camera, so there is no need to rely on experience to predict the precise installation position of the sealing device, which greatly increases the error tolerance of the installation position and improves the installation efficiency of the sealing device.

[0044] In practical use, the fixing mechanism 2 is first embedded in the front end of the connecting mechanism 1 to fix the two together, and the internal through holes are connected. Due to the setting of the transparent plate 21 at the front end of the fixing mechanism 2, the fixing mechanism 2 and the connecting mechanism 1 are kept sealed.

[0045] Next, the connecting mechanism 1 is installed on the observation window 3, so that the front fixing mechanism 3 is placed inside the observation window 3. Then, the endoscopic camera 4 is passed through the through holes in the connecting mechanism 1 and the fixing mechanism 2, and then through the through hole in the ball head 26 to abut against the transparent plate 21. A thin wire can be passed through the through holes in the connecting mechanism 1 and the fixing mechanism 2 to contact the ball head 26. According to the field of view captured by the endoscopic camera 4, the ball head 26 is rotated in the ball seat, so that the endoscopic camera 4 can accurately capture images of the GIS indoor knife switch and floor switch. Then, sealant is filled into the through holes in the connecting mechanism 1 and the fixing mechanism 2 to reinforce the internal endoscopic camera 4. Finally, the end cap 5 is threadedly connected to the connecting mechanism 1 to fix the endoscopic camera 4 inside the connecting mechanism 1 and the fixing mechanism 2. The through-hole in the ball head 26 is sized to match the endoscopic camera 4, and its diameter is smaller than the diameter of the through-holes in the connecting mechanism 1 and the fixing mechanism 2. Therefore, when filling with sealant, the sealant will not enter the through-hole in the ball head 26. The sealant directly stabilizes the endoscopic camera 4 by fixing the ball head 26 and the ball seat. The other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0046] Example 3:

[0047] This embodiment further defines the structure of the ball head 26 based on the above embodiment, such as... Figures 2-4As shown, a spherical notch is provided on the rear side of the ball head 26, and the axis of the through hole inside the ball head 26 coincides with the axis of the plane where the spherical notch is located. To facilitate adjustment of the ball head 26's rotation, the rear side of the ball head is designed as a planar spherical notch, making it easier to rotate the ball head 26 using a thin wire. Furthermore, the coincidence of the axis of the through hole inside the ball head 26 with the axis of the plane where the spherical notch is located ensures that the endoscopic camera 4 can accurately pass through the through holes in the connecting mechanism 1 and the fixing mechanism 2, enter the through hole in the ball seat 26, and abut against the transparent plate 21, thus ensuring a stable field of view for the endoscopic camera 4. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0048] Example 4:

[0049] This embodiment further defines the structure of the fixing mechanism 2 based on the above embodiment, such as... Figures 2-4 As shown, the ball seat at the front end of the fixing mechanism 2 is a hemispherical cavity that matches the ball head 26. This ball seat structure is designed to allow the ball head 26 to rotate more easily within the ball seat, thereby adjusting the field of view of the endoscopic camera 4, while simultaneously ensuring a seal between the ball head 26 and the ball seat to prevent leakage of high-pressure sulfur hexafluoride gas inside. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0050] Example 5:

[0051] This embodiment further defines the structure of the fixing mechanism 2 based on the above embodiment, such as... Figures 2-4 As shown, the LED light strip 22 is also equipped with a uniform light-diffusing lens 24 to ensure even light dispersion. The uniform light-diffusing lens 24 adopts an aspherical microstructure, and the divergence angle is controlled within 3°±0.5°. Together with the light-blocking plate 23, it effectively eliminates light spot overlap, ensures the signal-to-noise ratio of the endoscopic camera 4, and ensures clear image capture. The other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0052] Example 6:

[0053] This embodiment further defines the structure of the fixing mechanism 2 based on the above embodiment, such as... Figures 2-4 As shown, the power cord 25 of the LED light strip 22 passes sequentially through the through holes in the connecting mechanism 1 and the fixing mechanism 2, and finally extends out from the fitting point between the endoscopic camera 4 and the end cover 5 to connect to an external power source. Other parts of this embodiment are the same as those in the above embodiments and will not be described again.

[0054] Example 7:

[0055] This embodiment, based on the above embodiment, further defines the connection relationship between the connecting mechanism 1, the observation window 3, and the fixing mechanism 2. The connecting mechanism 1 and the observation window 3 are threadedly connected, and the connecting mechanism 1 and the fixing mechanism 2 are also threadedly connected. The other parts of this embodiment are the same as those in the above embodiment and will not be described again.

[0056] Example 8:

[0057] This embodiment, based on the above embodiment, further adds an O-ring seal 6, such as... Figures 1-3 As shown, an O-ring seal 6 is also provided between the connecting mechanism 1 and the observation window 3. The O-ring seal 6 is provided to further ensure the sealing effect between the connecting mechanism 1 and the observation window 3. The other parts of this embodiment are the same as those in the above embodiment, and will not be described again.

[0058] It is understood that the working principle and process of the detection camera sealing device structure according to one embodiment of the present invention, such as the uniform light lens 24 and the O-ring seal 6, are existing technologies and are well known to those skilled in the art, and will not be described in detail here.

[0059] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
