[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1-2 In an embodiment of the present utility model, a pipeline leakage detection device includes a telescopic rod 2, a spray detection mechanism and a lifting and adjusting mechanism.

[0023] The bottom end of the telescopic rod 2 is fixedly sleeved with an anti-slip sleeve 1, which is convenient for gripping and reduces the possibility of accidental slipping. The top of the telescopic rod 2 is fixedly connected with a spray detection mechanism, which includes a vertical plate 8, a spray frame 6 and a spray pipe 13. The top of the telescopic rod 2 is fixedly connected with a vertical plate 8, and the vertical plate 8 is connected to the spray frame 6. The inner end surface of the spray frame 6 is provided with a plurality of spray grooves 15 that are evenly and circumferentially distributed, and the outer surface of the spray frame 6 is fixedly connected with the spray pipe 13. One side of the vertical plate 8 is fixedly connected to a water tank 10, and a water pump 12 is fixedly installed on the lower surface of the water tank 10. The water inlet end of the water pump 12 is fixedly connected to the bottom of the water tank 10, and the water outlet end of the water pump 12 is fixedly connected to the spray pipe 13, and an observation line 11 is provided on the outer surface of the water tank 10. The upper surface of the spray frame 6 is fixedly connected with a plurality of lighting lamps 14 that are evenly and circumferentially distributed.

[0024] When in use, we put the spray frame 6 on the outside of the pipeline. Under the operation of the water pump 12, the liquid in the water tank 10 is sent into the spray frame 6 through the spray pipe 13, and is sprayed to the outside of the pipeline through the spray trough 15. The spraying range can be changed by moving the telescopic rod 2, which facilitates spraying detection at different positions.

[0025] It should be noted that, through the design of the spray frame 6 and the spray pipe 13, the function of automatically and evenly spraying soapy water is realized, which improves the detection efficiency and reduces the complexity and labor intensity of manual operation. Due to the multiple uniform and circularly distributed spray grooves 15 opened on the inner end face of the spray frame 6, the soapy water is ensured to be evenly sprayed on the pipe surface, effectively covering the detection area, and improving the accuracy and sensitivity of the detection. In conjunction with the setting of the water tank 10 and the water pump 12, water can be continuously supplied for spraying to ensure the continuity and stability of the spray detection process, avoid detection interruption due to insufficient water, and improve detection reliability. In addition, the lighting lamp 14 fixedly connected to the spray frame 6 provides sufficient light, especially in low-light environments, which enhances the detection visibility and facilitates the operator to observe and confirm the leakage location.

[0026] The vertical plate 8 is provided with a lifting and adjusting mechanism, which includes a driving motor 3, a threaded rod 9 and a lifting block 7. The front end surface of the vertical plate 8 is provided with a lifting groove 5, and the threaded rod 9 is rotatably connected between the upper and lower inner walls of the lifting groove 5, and the inner wall of the lifting groove 5 is slidably connected to the lifting block 7. The threaded rod 9 passes through the lifting block 7 and is threadedly connected thereto. The front end surface of the vertical plate 8 is provided with a mounting groove 4, and the lower inner wall of the mounting groove 4 is fixedly connected to the driving motor 3. The bottom end of the threaded rod 9 passes through the lifting groove 5 and is fixedly connected to the output end of the driving motor 3 through a coupling.

[0027] When in use, the driving motor 3 works, thereby driving the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the lifting block 7, and the lifting block 7 is slidably connected due to the lifting slot 5, the lifting block 7 will move in the vertical direction, thereby achieving the effect of changing the spraying position, which is convenient for detection.

[0028] It should be noted that, through the cooperation of the drive motor 3, the threaded rod 9 and the lifting block 7, the height of the spray detection mechanism can be adjusted to adapt to the height of the pipeline, thereby enhancing the applicability and flexibility of the device. The threaded connection design of the threaded rod 9 and the lifting block 7 ensures the smoothness and precision of the adjustment process, so that the spray detection mechanism can work stably at the required height. The drive motor 3 provides a lifting function, which reduces the tedious steps and labor intensity of manual adjustment. The operator only needs to achieve height adjustment through simple control, thereby improving work efficiency.

[0029] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
