DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figure 1-Figure 4 As shown, the filter seal detection device of this embodiment includes a frame 1 and a detection tank 2 arranged on the frame 1, the frame 1 is provided with a gas filling and discharging mechanism 3, the detection tank 2 is provided with a detection frame 4, the detection frame 4 is arranged in the detection tank 2 in a liftable manner, the frame 1 is provided with a lifting cylinder 5, the lifting cylinder 5 is connected to the detection frame 4, and is used to drive the detection frame 4 to lift, the detection frame 4 is provided with a positioning mechanism 6, and the positioning mechanism 6 includes:

[0023] A positioning block 61 is arranged on the upper side of the detection frame 4;

[0024] A fixed cylinder 62 is arranged on the upper side of the detection frame 4;

[0025] The fixed block 63 is connected to the fixed cylinder 62 and is driven by the fixed cylinder 62 to move closer to / away from the positioning block 61; the positioning block 61 is provided with an inflation hole 611 and an deflation hole 612, and the inflation pipe and deflation pipe of the inflation and deflation mechanism 3 are respectively connected to the inflation hole 611 and the deflation hole 612; the frame 1 is provided with a camera and a processor for image recognition, the camera faces the detection slot 2, and the camera, the lifting cylinder 5 and the fixed cylinder 62 are all connected to the processor.

[0026] Through the above technical solution, when the device is used to detect filter leaks, the device is in the initial state, at this time there is water in the detection tank 2, the detection frame 4 is located on the water surface, and the distance between the fixed block 63 and the positioning block 61 is at the maximum position; then the employee grabs the filter and places it on the detection frame 4, wherein one end of the filter for air inlet and air outlet faces the positioning block 61, at this time the air inlet and air outlet of the filter are aligned with the inflation hole 611 and the deflation hole 612 on the positioning block 61, then the fixed cylinder 62 is operated to drive the fixed block 63 to move toward the positioning block 61, the fixed block 63 first contacts one end of the filter, and then pushes the filter The filter moves toward the positioning block 61 until the other end of the filter contacts the positioning block 61, and then the lifting cylinder 5 operates to drive the detection frame 4 to descend until the detection frame 4 and the filter are completely submerged in water; then the inflation and deflation mechanism 3 operates to detect leaks. At the same time, the camera reads the water surface video data, and the processor uses image processing software to pre-process the collected original image to improve the image quality and extract the feature quantity (bubble) of interest from it; finally, the pattern recognition technology is used to classify and organize the acquired feature quantities to complete the system detection, so as to determine whether the filter is leaking, without the need for naked eye observation to avoid omissions.

[0027] Specifically, a speaker is provided on the rack 1, and the speaker is connected to the processor. When bubbles are detected, the speaker broadcasts to further avoid omissions.

[0028] After the detection is completed, the lifting cylinder 5 operates to drive the leak detection frame to rise. After the leak detection frame leaves the water surface, the fixing cylinder 62 operates to drive the fixing block 63 away from the positioning block 61 and return to the initial state. At this time, the employee removes the filter that has been tested and replaces it with the filter to be tested.

[0029] The water inlet / outlet of the detection frame 4 is controlled by the lifting cylinder 5, which is shorter and more efficient than controlling the water to enter the detection tank 2 without a filter.

[0030] As an improved specific implementation, a partition plate 21 is provided in the detection slot 2, and the partition plate 21 divides the detection slot 2 into two parts, and the two parts both have detection frames 4.

[0031] Through the above technical scheme, there are detection frames 4 in both parts. When one detection frame 4 is located under the water surface for detection, the employee can remove the filter on the other detection frame 4 and install the filter to be inspected. When the detection is completed, the detection frame 4 under the water surface rises out of the water, and the detection frame 4 on the water surface descends into the water to switch the detection. The employee continues to remove the filter that has completed the detection and replace it with the filter to be inspected. The detection efficiency is high, and the partition 21 separates the water in the two parts to avoid the mutual influence of ripples when the detection frame 4 is out of water and into water, thereby ensuring the accuracy of image recognition.

[0032] Specifically, there are two cameras, which are respectively located on the upper sides of the two parts, to collect image data of the corresponding parts.

[0033] As an improved specific implementation, the detection frame 4 has two sets of positioning mechanisms 6 .

[0034] Through the above technical solution, two sets of positioning mechanisms 6 can detect two filters at the same time without affecting the operation (one filter is placed with one hand), thereby further improving the detection efficiency.

[0035] As an improved specific implementation, the detection frame 4 is composed of a plurality of longitudinal bars 41 and transverse bars 42 , the lower ends of the longitudinal bars 41 and transverse bars 42 are streamlined, and the upper ends of the longitudinal bars 41 and transverse bars 42 are streamlined.

[0036] Through the above technical solution, the detection frame 4 composed of the longitudinal rod 41 and the horizontal rod 42 is hollowed out, so that the resistance of the detection frame 4 when entering and exiting the water is small, the energy consumption during driving is reduced, energy saving and emission reduction are reduced, and costs are reduced.

[0037] As an improved specific implementation, a lifting groove 71 is provided on the side of the detection groove 2 , and a lifting block 72 is provided on the side of the detection frame 4 . The lifting block 72 is slidably connected to the lifting groove 71 .

[0038] Through the above technical solution, the lifting block 72 is slidably connected to the lifting slot 71, and the position is stable during the lifting process.

[0039] As an improved specific implementation, a sealing ring 81 is provided on a side of the positioning block 61 facing the fixing block 63 , and a groove 82 is provided on a side of the fixing block 63 facing the positioning block 61 .

[0040] Through the above technical solution, when the positioning mechanism 6 fixes the filter, one end of the filter connection hole is wrapped by the sealing ring 81, which has good sealing performance, and the other end is partially accommodated in the groove 82, with a large contact area, so that the positioning is highly stable.

[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
