[0002] Membrane pool is a commonly used water treatment equipment. Its working principle is to use the characteristics of semi-permeable membrane to separate impurities and ions in water, so as to achieve the purpose of purifying water quality. At present, in the process of management and operation, it is found that white aggregated bubble-like floating objects often appear in membrane pools, and they are not easy to disappear. If they exist for a long time, they will not only affect the hygiene of the pool surface, breed bacteria, but also cause the water quality in the pool to deteriorate. In order to reduce the adverse effects on the water quality in the pool, it is necessary to clean it regularly.

[0003] In the prior art, the cleaning spray is installed in the white foam gathering area, and mechanical external force is used to break it. Since the floating position of the white foam-like floating objects in the membrane pool is uncertain, it is impossible to effectively determine the location of the foam gathering area. In addition to the gathering area, there are also a small amount of foam in other areas. Only the gathering area is cleaned, which has the problem of incomplete cleaning. In addition, the attachments on the membrane pool wall and the middle beam are difficult to clean, and a large impact force is required to rinse them clean. Utility Model Content

The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] Example 1: Please refer to the attached Figure 1, an automatic membrane pool cleaning device, comprising a liquid-passing pipe 20 arranged parallel to the width direction of the membrane pool 10 and a driving mechanism 30 for driving the liquid-passing pipe 20 to move along the length direction of the membrane pool 10;

[0027] Please refer to the attached Figure 1 The liquid pipe 20 is set on the membrane pool 10, and the lower part of the liquid pipe 20 is connected with a nozzle along its length direction, wherein the nozzle close to the membrane pool wall and the middle beam is a first high-pressure nozzle 1 arranged obliquely, which is used to better remove the attachments on the membrane pool wall and the middle beam; the other positions are ordinary nozzles 2, which are used to eliminate white foam floating on the water surface; please refer to the attached Figure 2 The interior of the liquid passage tube 20 is divided into a first cavity 201 and a second cavity 202 by a partition, the first cavity 201 is connected to the first high-pressure nozzle 1, the second cavity 202 is connected to the ordinary nozzle 2, and the ends of the liquid passage tube 20 are connected to two liquid supply hoses 3 respectively connected to the first cavity 201 and the second cavity 202, and the water pressures of the two liquid supply hoses 3 are controlled separately.

[0028] The driving mechanism 30 includes two sets of screw slider structures respectively arranged at the two ends of the liquid passage 20. Figure 3 , and the lead screw 301 is arranged at one end of the liquid pipe 20 parallel to the length direction of the membrane pool 10, and the matching slider 302 is fixedly connected to a mounting ring 4 on one side, and the mounting ring 4 is sleeved on the end of the liquid pipe 20. One end of the lead screw 301 is connected to a motor 303 for driving the lead screw 301 to rotate, and the other end of the lead screw 301 is provided with a fixed block 9 fixed on the shore of the membrane pool, and the lead screw 301 is rotatably connected to the fixed block 9 through a bearing.

[0029] When in use, the motor 303 is started to drive the lead screw 301 to rotate, the slider 302 is driven to translate along the lead screw 301, and the liquid pipe 20 moves accordingly, and the liquid pipe 20 moves from one side of the membrane pool 10 to the opposite side thereof; at the same time, the liquid supply hose 3 is connected to the water source or cleaning liquid, and the water body leading to the first cavity 201 is controlled to be high-pressure water, and the water body leading to the second cavity 202 is controlled to be low-pressure water. The high-pressure water passes through the first cavity 201 and is sprayed from the first high-pressure nozzle 1, and the attachments on the membrane pool wall and the middle beam are well washed. The low-pressure water passes through the second cavity 202 and is sprayed from the ordinary nozzle 2 to remove the white foam and other objects floating on the water surface. Then the nozzle of the device sweeps across the membrane pool, which can comprehensively clean the white foam and other objects on the water surface of the membrane pool, and can well remove the attachments on the membrane pool wall and the middle beam. In addition, by providing relatively suitable low-pressure water and high-pressure water to the common nozzle 2 and the first high-pressure nozzle 1 respectively, the problem of leakage of the common nozzle 2 caused by high-pressure water can be avoided.

[0030] Embodiment 2: This embodiment differs from Embodiment 1 in that:

[0031] Please refer to the attached Figure 1 and Figure 3 The driving mechanism 30 includes a screw slider structure arranged at the end side of the liquid pipe 20 and a guide structure arranged at the other end side of the liquid pipe 20.

The working principle of the safety valve structure 7 is: under the action of high pressure, the valve core automatically closes by overcoming the spring force, and under low pressure or no pressure, the spring pushes the valve core to automatically open. The working principle of the pressure relief valve structure 8 is: under low pressure or no pressure, the valve core automatically closes under the action of the spring force, and under high pressure, the valve core automatically opens by overcoming the spring force. The specific structures of the safety valve structure 7 and the pressure relief valve structure 8 are both existing public technologies and will not be described here.
