Description

Technical Field

[0001] This utility model relates to the field of butterfly valve switch technology, specifically a butterfly valve switch with a camera. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve. It can be used to control the flow of various types of fluids, including air, water, steam, corrosive media, slurry, oil, liquid metals, and radioactive media. In pipelines, it primarily functions as a shut-off and throttling device. The butterfly valve's opening and closing element is a disc-shaped plate that rotates around its own axis within the valve body, thereby achieving opening, closing, or regulation.

[0003] In real life, butterfly valves that control ventilation doors in some mines are mostly opened and closed using limit switches or similar methods. When the limit switch is damaged or the circuit is blocked, it can cause misjudgment, which can lead to the failure of the automation process of the mine's unattended ventilation fan online monitoring system, thus requiring human intervention. If the human intervention time exceeds a certain period of time, it can lead to serious ventilation accidents and even casualties. Therefore, a butterfly valve switch with a camera is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a butterfly valve switch with a camera to solve the problem mentioned in the background art. For butterfly valves in some mines that control air doors, their opening and closing are mostly done by limit switches or the like. When the limit switch is damaged or the circuit is blocked, it will cause misjudgment, which will cause the automation process of the mine unattended ventilation fan online monitoring system to fail, thus requiring human intervention. When the human intervention time exceeds a certain period of time, it will lead to serious ventilation accidents and even cause casualties.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a butterfly valve switch with a camera, comprising:

[0007] A butterfly valve switch body, wherein a mounting base is fixedly provided at the top of the butterfly valve switch body;

[0008] A support assembly, comprising a base, a connecting frame, a sliding rod, a fixing element, a movable seat, and a support frame;

[0009] The outer wall of the base is engaged with the inner wall of the mounting base, the bottom end of the connecting frame is fixedly mounted on the top end of the base, the outer wall of the slide rod penetrates one side of the connecting frame, the fixing member is fixedly mounted on one end of the slide rod, one side of the movable seat is fixedly mounted on the other end of the slide rod, and the back of the support frame is fixedly mounted on the front of the movable seat.

[0010] The bottom of the camera is connected to the top of the support frame via a damping pivot.

[0011] Furthermore, the total length of the slide bar and the movable seat is adapted to the length from one side of the connecting frame to the other side of its inner wall.

[0012] Furthermore, the fastener includes a connecting block, and a first lead screw is provided through the bottom end of one side of the connecting block, and one end of the first lead screw is threadedly connected to one side of the connecting frame.

[0013] Furthermore, a first torque is fixedly provided at the other end of the first lead screw.

[0014] Furthermore, the device also includes an installation assembly, which comprises a second lead screw, a second rotary knob, a moving block, a connecting rod, and a locking rod.

[0015] The outer wall of the second lead screw passes through the top of the connecting frame and the base respectively. The bottom end of the second rotary knob is fixedly set at the top of the second lead screw. The inner wall of the moving block is threaded onto the outer wall of the second lead screw. One end of the connecting rod is rotatably connected to one side of the moving block. One side of the outer wall of the clamping rod is rotatably connected to the other end of the connecting rod.

[0016] Furthermore, the bottom end of the second lead screw is rotatably connected to the bottom end inside the base.

[0017] Furthermore, one end of the lever penetrates the inner wall of both the base and the mounting base to the outside of the mounting base.

[0018] This utility model has the following beneficial effects:

[0019] This invention comprises a camera, a movable base, and a fixing component. Moving the movable base left and right moves the camera until it contacts the inner wall of the connecting frame, where it is then fixed in place by the fixing component. The camera is then rotated to a suitable angle. The camera provides redundant judgment on whether the damper / butterfly valve is in position. Even if the limit switch is damaged or malfunctions, it does not affect the camera's image recognition of the damper / butterfly valve's position. Through intelligent image analysis, combined with an industrial computer system, a mechanically-free damper / butterfly valve position judgment system can be realized, completely avoiding automation system failures caused by misjudgments of damper opening and closing. Furthermore, the camera's position and angle can be adjusted according to the butterfly valve's installation location, thus meeting various needs.

[0020] Based on the aforementioned beneficial effects, by providing a second rotary knob and a locking rod, rotating the second rotary knob drives the moving block to move upward through the second lead screw, and then drives the two locking rods to move towards each other through the connecting rod until the locking rods separate from the mounting base, and then move upward to remove the base. This method facilitates the disassembly of the support components, and the whole process is time-saving and labor-saving, making it convenient for later maintenance of the camera.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figure 1-4 As shown, this utility model is a butterfly valve switch with a camera, comprising:

[0033] The butterfly valve switch body 1 has a mounting base 2 fixedly provided at its top end;

[0034] The butterfly valve switch body 1 is mainly used for controlling the ventilation door in the mine, and the mounting base 2 is mainly used for connection and support.

[0035] The bracket assembly 3 includes a base 301, a connecting frame 302, a slide rod 303, a fixing member 304, a movable seat 305, and a support frame 306.

[0036] The outer wall of the base 301 is engaged with the inner wall of the mounting base 2. The bottom end of the connecting frame 302 is fixedly mounted on the top end of the base 301. The outer wall of the slide rod 303 penetrates one side of the connecting frame 302. The fastener 304 is fixedly mounted on one end of the slide rod 303. One side of the movable seat 305 is fixedly mounted on the other end of the slide rod 303. The back of the support frame 306 is fixedly mounted on the front of the movable seat 305.

[0037] The connecting frame 302 is U-shaped, with two sliding rods 303 slidably provided on both sides. The sliding rods 303 can be moved and limited, and the position of the moving seat 305 can be adjusted left and right. The fixing member 304 can be used to fix and limit the position of the sliding rods 303. The support frame 306 is L-shaped and is mainly used for connection and support.

[0038] Camera 4, the bottom end of camera 4 is connected to the top end of support frame 306 via a damping pivot;

[0039] Camera 4 uses an AI intelligent camera, model CX200pro+, which redundantly judges whether the butterfly valve is in position through the camera. Even if the limit switch is damaged or fails, it will not affect the camera's image recognition of the damper / butterfly valve being in position. Camera 4 does not contact the support frame 306 during rotation.

[0040] The total length of the slide bar 303 and the movable seat 305 is adapted to the length from one side of the connecting frame 302 to the other side of its inner wall;

[0041] The fastener 304 includes a connecting block 3041, a first lead screw 3042 is provided through the bottom end of one side of the connecting block 3041, one end of the first lead screw 3042 is threadedly connected to one side of the connecting frame 302, and a first knob 3043 is fixedly provided at the other end of the first lead screw 3042.

[0042] The outer wall of the first lead screw 3042 is threaded to one side of the connecting block 3041, and the outer wall of the first knob 3043 is provided with anti-slip threads to facilitate the rotation of the first knob 3043.

[0043] Working principle: Based on the butterfly valve's switch position, the movable seat 305 is moved left or right. The movement of the movable seat 305 drives the support frame 306 to move, which in turn drives the camera 4 to move left or right until the movable seat 305 contacts the inner wall of the connecting frame 302. Then, the first rotary knob 3043, which is close to the connecting frame 302, is rotated. The rotation of the first rotary knob 3043 drives the first lead screw 3042 to move until the first lead screw 3042 is threadedly connected to the connecting frame 302. Then, the angle of the camera 4 is adjusted so that it can redundantly judge whether the damper / butterfly valve is in position. Through intelligent image analysis, combined with an industrial computer system, a damper / butterfly valve position judgment system without mechanical joints can be realized.

[0044] This step ensures that even if the limit switch is damaged or fails, it will not affect the camera's image recognition of the damper / butterfly valve being in position, thus completely avoiding the problem of automation system failure caused by misjudging the damper's opening and closing.

[0045] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0046] Mounting component 5 includes a second lead screw 501, a second rotary knob 502, a moving block 503, a connecting rod 504, and a locking rod 505;

[0047] The outer wall of the second lead screw 501 passes through the top of the connecting frame 302 and the base 301 respectively. The bottom end of the second rotary knob 502 is fixedly set at the top of the second lead screw 501. The inner wall of the moving block 503 is threaded on the outer wall of the second lead screw 501. One end of the connecting rod 504 is rotatably connected to one side of the moving block 503. One side of the outer wall of the clamping rod 505 is rotatably connected to the other end of the connecting rod 504.

[0048] The second lead screw 501 is connected to the connecting frame 302 and the base 301 bearing. The outer wall of the second rotary knob 502 is also provided with anti-slip threads, and the top of the second rotary knob 502 does not contact the bottom of the moving seat 305, so as to avoid motion interference. During the process of the moving block 503 moving up and down along the second lead screw 501, the outer wall of the locking rod 505 is always in contact with the inner wall of the base 301.

[0049] The bottom end of the second lead screw 501 is rotatably connected to the bottom end inside the base 301;

[0050] One end of the lever 505 passes through the inner wall of the base 301 and the mounting base 2 to the outside of the mounting base 2;

[0051] Working principle: Rotate the second knob 502. The rotation of the second knob 502 drives the moving block 503 to move upward through the second lead screw 501. The upward movement of the moving block 503 drives the two locking rods 505 to move towards each other through the two connecting rods 504 until the locking rods 505 are separated from the mounting base 2. Then the connecting frame 302 moves upward until the base 301 is separated from the mounting base 2.

[0052] This step allows for easy assembly and disassembly of bracket component 3, saving time and effort throughout the process and making it convenient to operate.
