Description

Technical Field

[0001] This utility model relates to the field of automatic cleaning technology for underwater probes, specifically to a device for automatic cleaning of underwater probes. Background Technology

[0002] Underwater probes are critical sensors for real-time monitoring in fields such as chemical engineering, environmental protection, water treatment, and unmanned water plants. During operation, they are easily contaminated by oil, sludge, and other pollutants, forming scale buildup that reduces detection accuracy. Currently, cleaning mainly relies on manual methods, which are not only labor-intensive but also pose risks of falls near edges and probe damage from impacts. Existing automatic cleaning devices are often costly, prone to probe damage, and lack adaptability, failing to meet the demands of continuous automated monitoring under complex conditions. Therefore, we have designed an automatic underwater probe cleaning device that enables timed, efficient, and non-destructive cleaning, flexibly adapting to different operating conditions. It effectively removes scale while ensuring probe safety, significantly improving the accuracy and reliability of monitoring data. Utility Model Content

[0003] The purpose of this invention is to provide an automatic cleaning device for underwater probes, which has the advantages of timed, efficient, and non-destructive cleaning, and flexible adaptation to different working conditions. It solves the problems of existing underwater probes being submerged in complex water quality for a long time, where the sensing surface is easily covered by oil, biological slime or other pollutants, leading to distortion of monitoring signals and serious reduction in accuracy; and the problems of high labor intensity, high operational risks, difficulty in scientifically controlling the cleaning interval and effect, and potential damage to the probe during the cleaning process. At the same time, it overcomes the defects of existing automatic cleaning devices, such as complex structure, high cost, non-adjustable cleaning intensity, easy wear on the sensitive membrane surface of the probe or poor adaptability.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic underwater probe cleaning device, comprising a flushing device, a lifting lug welded to the upper part of the flushing device, the lifting lug of the flushing device being connected to a winch via a steel wire rope, the top of the flushing device being connected to a flushing channel via a retractable flushing pipe, a pressure sensor installed inside the flushing channel, and the other end connected to a closed water tank, a throttle valve installed on the closed water tank to control the water pressure, the throttle valve being controlled by a human-machine interface, the closed water tank being filled with water by a flushing pump, the flushing pump being connected to a distribution box, and the winch being controlled by a servo motor; the winch and the servo motor are fixed to the upper end of a support frame, and the support frame, probe base, and flushing channel are connected to form the overall frame of this device.

[0005] Preferably, the rinsing device is in the shape of a tubular shell, with multiple rinsing holes on the inner wall of the tubular shell, the retractable rinsing pipe communicating with the inner cavity of the rinsing device, and a water outlet at the bottom of the rinsing device.

[0006] Preferably, the winch and the servo motor are both fixed to the upper end of the bracket.

[0007] Preferably, the flushing channel is divided into two parts: one part is a water passage channel set in the probe base, and the other part is a flushing channel located inside the flushing device, and the two are connected by a telescopic flushing pipe.

[0008] Preferably, the enclosed water tank is filled with water by a flushing pump.

[0009] Preferably, casters are installed at the bottom of the bracket.

[0012] Preferably, the lower end of the rinsing device has a conical structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves automatic lifting and precise positioning of the flushing device through a winch, wire rope, and retractable flushing pipe precisely controlled by a servo motor. It can accurately lower and reset the flushing cover. The system can perform 360° flushing of underwater probes without dead angles, and can flexibly adjust the flushing pressure and time according to the type of probe and the degree of scaling. It effectively replaces the high-risk and low-efficiency manual cleaning method, significantly reduces maintenance costs and probe damage risks, and has the advantages of high efficiency, simple operation, strong adaptability and low maintenance costs. It has a wide range of applications.

[0014] 2. This utility model integrates a flushing pump, a closed water tank, a pressure control system with a throttling valve, and a pressure sensor within the flushing channel to form a closed-loop water pressure management unit. This system provides stable and adjustable cleaning water pressure, ensuring efficient flushing of various types of dirt with high-pressure water flow. Simultaneously, through pressure relief via the throttling valve and monitoring by the pressure sensor, the water pressure is consistently controlled within a safe threshold, effectively preventing impact damage to the sensitive membrane surface of the probe caused by excessive water pressure, thus achieving a balance between high efficiency and non-destructive operation.

[0015] 3. This utility model adopts a modular frame design, connecting the bracket, probe base, and flow channel into a stable overall load-bearing frame, ensuring the stability and reliability of the equipment operation. Simultaneously, the probe base can flexibly adjust the probe's fixed height via a fixing nut and threaded support rod, and the casters at the bottom of the bracket facilitate overall movement. This allows the device to quickly adapt to different models, installation positions, and operating conditions of underwater probes, demonstrating exceptional versatility and flexibility.

[0020] Please see Figures 1-3 An automatic underwater probe cleaning device includes a flushing device 1. A lifting lug 2 is welded to the upper part of the flushing device 1. The lifting lug 2 of the flushing device 1 is connected to a winch 9 via a steel wire rope. The top of the flushing device 1 is connected to a flushing channel 5 via a retractable flushing pipe 3. A pressure sensor 14 is installed inside the flushing channel 5, and the other end is connected to a closed water tank 16. A throttle valve is installed on the closed water tank 16 to control the water pressure. The throttle valve is controlled by a human-machine interface 21. The closed water tank 16 is filled with water by a flushing pump 15, which is connected to a power distribution box 18. The winch 9 is controlled by a servo motor 8. The winch 9 and the servo motor 8 are fixed to the upper end of a bracket 7. The bracket 7, the probe base 6, and the flushing channel 5 together form the overall frame of the device.

[0021] Please see Figures 1-3 The rinsing device 1 has a tubular shell shape, and multiple rinsing holes 4 are provided on the inner wall of the tubular shell. The retractable rinsing pipe 3 is connected to the inner cavity of the rinsing device 1, and the rinsing device 1 has a water outlet at the bottom.

[0022] Specifically, the winch 9 and the servo motor 8 are connected and fixed to the upper end of the bracket 7.

[0023] Please see Figure 1 The flushing channel 5 is divided into two parts: one part is a water passage channel set in the probe base 6, and the other part is a flushing channel located inside the flushing device 1. The two are connected by a telescopic flushing pipe 3.

[0024] Please see Figure 1 , Figure 3 The sealed water tank is filled with water by flushing pump 15.

[0025] Please see Figure 1 One end of the flushing pump 15 is connected to the distribution box 18.

[0026] To improve the flexibility of this device, casters 19 are installed at the bottom of the bracket 7, preferably self-locking casters.

[0027] In some preferred embodiments, the probe base 6 is threadedly connected to an adjusting support rod 11 and a fixing nut 20 that mates with the adjusting support rod 11, and the lower end of the adjusting support rod 11 is used to connect the probe.

[0028] To improve the corrosion resistance and service life of the rinsing device, the rinsing device 1 is made of stainless steel.

[0029] In some other preferred embodiments, the lower end of the flushing device 1 is a conical structure. In this structure, the circumferentially sprayed water will form a local positive pressure at the bottom conical part of the flushing device 1, which is in the form of a pipe shell, which helps to clean the bottom of the probe 10.

[0030] During use, parameter settings and status checks are performed as follows: The automatic operation interval, flushing time, flushing pressure and other parameters are set through the human-machine interface, and the status of the servo motor 8 and the liquid level of the closed water tank 16 is checked for alarms. Automatic operation process: After the system starts, the flushing pump 15 is turned on, and the flushing pressure is controlled by the electrically adjustable throttle valve 17. The servo motor is controlled to rotate forward, driving the winch 9 to release the steel wire rope 12. The flushing device 1 descends to the position of the probe 10 by its own weight and covers it. Water is sprayed out from the flushing hole through the flushing channel to flush the probe 10 from all directions. After the preset flushing time is reached, the servo motor 8 reverses, driving the winch 9 to wind the steel wire rope 12 and lift the flushing device 1 back to the initial position. After the flushing device is reset, the flushing pump 15 is turned off.

[0031] During the rinsing process, in order to achieve a better rinsing effect, the winch 9 can be controlled to raise and lower the wire rope 12 to adjust the height of the rinsing device and thoroughly clean the probe 10.
