DETAILED DESCRIPTION

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0027] As shown in Figures 1-6 The present application provides a non-negative pressure water supply equipment self-cleaning device, which comprises a non-negative pressure water supply equipment assembly 1, the non-negative pressure water supply equipment assembly 1 comprising a water storage tank 11, a cover 12 being fitted on the upper end of the water storage tank 11, the cover 12 being used for sealing the water storage tank 11, and a connecting pipe (not marked in the figure) being installed on the water storage tank 11, and a water pump 13 being connected to one end of the connecting pipe, the water pump 13 being used for supplying water into the water storage tank 11;

[0028] A control valve 14 being fixedly installed on one side of the lower part of the water storage tank 11, the control valve 14 being connected with the water storage tank 11 through a water outlet pipe, and one end of the water outlet pipe extending into the inside of the water storage tank 11, the control valve 14 playing a role of closing the water outlet pipe;

[0029] And a stirring assembly 2 being installed on the cover 12, the stirring assembly 2 being used for stirring the mixture of impurities and water in the water storage tank 11, and the stirring assembly 2 comprising a mounting bracket 21 being fixedly installed on the cover 12, a motor 22 being fixedly installed on the mounting bracket 21, an output end of the motor 22 penetrating through the cover 12 and extending into the inside of the water storage tank 11, and a telescopic unit being fixedly installed on the output end of the motor 22;

[0030] The telescopic unit comprises a fixed shaft 23 fixedly installed at the output end of the motor 22, and an active shaft 24 movably sleeved at one end of the fixed shaft 23, and two groups of active grooves 25 symmetrically arranged are formed in the active shaft 24, and an active side block 26 adapted to the active grooves 25 is fixedly installed on the fixed shaft 23, and the fixed shaft 23 slides along the linear direction of the active grooves 25 through the active side block 26, so as to realize the telescopic function;

[0031] And the rotating blades 27 are fixedly installed on the active shaft 24 and the fixed shaft 23, and when the motor 22 drives the fixed shaft 23 to rotate, the active shaft 24 is synchronously rotated, and the rotating blades 27 installed on the active shaft 24 and the fixed shaft 23 will agitate the water body at a high speed. The water flow flowing at a high speed forms a circulation in the water storage tank 11, and the water flow will generate a certain impact force on the inner wall of the water storage tank 11. The impact force can scour the impurities that are not firmly attached to the inner wall of the water storage tank 11, so that the impurities are gradually loosened and separated from the inner wall, and then re-suspended in the water. For example, some dust, algae and other impurities that are slightly attached to the inner wall are easily washed away under the continuous impact of the water flow;

[0032] In order to filter and collect the impurities in the water, as shown in Figures 2-3 , a collecting assembly 3 is installed at one end of the fixed shaft 23, the collecting assembly 3 comprises a collecting net 31 installed on one end of the fixed shaft 23 through a bearing, two groups of connecting plates 33 are symmetrically fixedly installed on the collecting net 31, and a pull rod 32 is connected between the two groups of connecting plates 33, the pull rod 32 is in an inverted state and has two ends movably penetrating the cover 12 and extending into the water storage tank 11 to be connected with the connecting plates 33, and two groups of fasteners 34 are threadedly connected on the pull rod 32, and the two groups of fasteners 34 are respectively arranged at the upper and lower ends of the connecting plates 33 to fixedly connect the pull rod 32 and the connecting plates 33;

[0033] And a scraping ring (not marked in the figure) is arranged at the position where the collecting net 31 contacts the inner wall of the water storage tank 11, so that when the impurities slightly attached to the inner wall of the water storage tank 11 are agitated by the motor 22 driving the rotating blades 27, the operator uses the external hoisting equipment to pull the pull rod 32 to drive the collecting net 31 to move upward, and the collecting net 31 cleans the stubborn dirt attached to the inner wall of the water storage tank 11 through the scraping ring, until the active shaft 24 is completely sleeved on the fixed shaft 23 (refer to Figure 4 ), at this time, the collecting net 31 is located at the upper end position in the water storage tank 11, and can filter the impurities in the water to a certain extent;

[0034] In order to facilitate the cover 12 and the collecting net 31 to be taken out of the water storage tank 11, so as to clean the filtered impurities, as shown in Figures 4-5As shown, the side push rod 35 is fixedly installed at both ends of the pull rod 32 and is located at a relatively central position on the pull rod 32, so that when the movable shaft 24 is completely sleeved on the fixed shaft 23, the top end of the side push rod 35 is in contact with the bottom end of the cover body 12. At this time, if the impurities filtered on the collection net 31 need to be cleaned, the pull rod 32 is continuously pulled upward, and the side push rod 35 will move upward to push the cover body 12 to gradually separate from the water storage tank 11. At the same time, since the movable shaft 24 is connected with the collection net 31, the movable shaft 24 drives the collection net 31 to be pulled out of the water storage tank 11 synchronously during the lifting of the cover body 12. In this way, the impurities collected on the collection net 31 can be treated, simplifying the impurity cleaning process and improving the maintenance efficiency of the self-cleaning device of the non-negative pressure water supply equipment;

[0035] In order to ensure that the motor 22 drives the fixed shaft 23 and the movable shaft 24 to rotate, since the fixed shaft 23 and the movable shaft 24 are movably connected, the stability is lacking, such as Figure 6 As shown, a limiting unit is installed on the cover body 12, which includes two groups of fixed rings 36 fixedly installed on the pull rod 32, and the two groups of fixed rings 36 have a gap therebetween. Meanwhile, a fixed portion 37 is fixedly installed on one side of the fixed ring 36 on the cover body 12, and a rotating portion 38 is bearingly installed on the fixed portion 37. The rotating portion 38 has a notch groove (not marked in the figure) which is adapted in diameter to the pull rod 32, and the top end of the fixed portion 37 has a limiting portion 39 which can limit the rotating portion 38;

[0036] The rotating portion 38 is adapted to rotate along the center of the fixed portion 37, so that the notch groove is clamped in the gap between the two groups of fixed rings 36 and is clamped on the pull rod 32. In this application, a non-slip pad is arranged at the contact position between the rotating portion 38 and the two groups of fixed rings 36, which can be made of silica gel to enhance the friction and prevent the rotating portion 38 from sliding randomly. Through this series of structures, the stability of the pull rod 32 is enhanced, thereby providing stable support for the rotation of the fixed shaft 23 and the movable shaft 24, reducing the shaking caused by unstable connection, and ensuring the stability of rotation. (It should be noted that when the fixed shaft 23 and the movable shaft 24 are completely in the stretched state, the fixed ring 36 at the lower end is in contact with the top end of the cover body 12.)

[0037] In summary: when the inside of the water storage tank 11 needs to be cleaned, the motor 22 is operated, and its output end drives the fixed shaft 23 to rotate. Since the fixed shaft 23 and the movable shaft 24 are movably connected through the movable side block 26 and the movable groove 25, the movable shaft 24 also rotates and drives the rotating blade 27 to rotate, rapidly stirring the water body in the water storage tank 11. The water flow forms a cycle in the water tank, generating an impact force on the inner wall of the water storage tank 11, which can wash away the impurities such as dust and algae that are not firmly attached to the inner wall, making these impurities loose and re-suspended in the water;

[0038] When the rotating blade 27 stirs the water body, the operator uses external hoisting equipment to pull the pull rod 32. The pull rod 32 is U-shaped and inverted, and the two ends are movably penetrated through the connecting plate 33 on the collection net 31 and the cover body 12 and fixedly connected through two groups of fasteners 34. When the pull rod 32 is pulled, the collection net 31 moves upward, and the scraping ring can clean the stubborn dirt attached to the inner wall of the water storage tank 11. When the movable shaft 24 is completely sleeved on the fixed shaft 23, the collection net 31 is located at the upper end position in the water storage tank 11, and at this time, the collection net 31 can not only clean the dirt on the inner wall, but also filter and collect the suspended impurities in the water;

[0039] When the movable shaft 24 is completely sleeved on the fixed shaft 23, the top end of the side push rod 35 contacts the bottom end of the cover body 12. Continue to pull the pull rod 32 upward, the side push rod 35 pushes the cover body 12 to gradually separate from the water storage tank 11, and at the same time, the movable shaft 24 drives the collection net 31 to be pulled out of the water storage tank 11, so that the operator can handle the impurities collected on the collection net 31, and complete the impurity cleaning process.

[0040] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
