Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a water disinfection equipment and a water plant disinfection process based on the introduction of sodium hypochlorite.

[0034] Example 1: Please refer to Figure 1-Figure 4 , a water disinfection device, comprising a device body 1 and a water pipe 2, the device body 1 is provided with an output pipe 3, the end of the output pipe 3 is fixedly connected with a vertically arranged connecting pipe 4, the bottom end of the connecting pipe 4 is fixedly plugged into the water pipe 2, an upper winding assembly 5 is installed on the top of the connecting pipe 4, the bottom end of the water pipe 2 is fixedly connected with a receiving pipe 6, the receiving pipe 6 is located directly below the water pipe 2, a cleaning roller 7 is arranged in the receiving pipe 6, and a lower winding assembly 8 is installed at the bottom end of the receiving pipe 6;

[0035] The upper winding assembly 5 includes an upper rope body 501, the bottom end of which passes through the connecting tube 4 and is connected to the top end of the cleaning roller 7. The upper winding assembly 5 is used to drive the cleaning roller 7 to move vertically upward;

[0036] The lower winding assembly 8 includes a lower rope body 801, the top of which is connected to the bottom of the cleaning roller 7, and the lower winding assembly 8 is used to drive the cleaning roller 7 to move vertically downward;

[0037] The outer diameter of the cleaning roller 7 matches the inner diameter of the connecting tube 4, and the cleaning roller 7 is used to scrape off the crystals on the inner wall of the connecting tube 4;

[0038] When the device body 1 is running, the disinfectant is output to the water pipe 2 through the output pipe 3 and the connecting pipe 4. At this time, the cleaning roller 7 is stored in the storage tube 6. When the inner wall of the connecting pipe 4 is crystallized, the upper winding assembly 5 is operated to wind up the upper rope body 501, and drive the cleaning roller 7 to move vertically upward, forcing the cleaning roller 7 to enter the connecting pipe 4 and scrape off the crystals. When the cleaning is finished, the lower winding assembly 8 is operated to wind up the lower rope body 801, thereby driving the cleaning roller 7 to move vertically downward, forcing the cleaning roller 7 to return to the storage tube 6;

[0039] Among them, the disinfectant in this embodiment is set to sodium hypochlorite, the bottom end of the connecting pipe 4 extends to the center of the water pipe 2, the inner edge of the bottom end of the connecting pipe 4 is chamfered, the inner edge of the top end of the storage tube 6 is chamfered, the inner diameter of the storage tube 6 matches the outer diameter of the cleaning roller 7, and in the initial state, the cleaning roller 7 is completely located in the storage tube 6, and there is only a straight upper rope body 501 in the connecting pipe 4, and the upper rope body 501 has a small diameter, which has little obstruction to the transportation of the disinfectant;

[0040] When in use, when the device body 1 is started, the diluted disinfectant enters the connecting pipe 4 through the output pipe 3, and then enters the water pipe 2 through the bottom end of the connecting pipe 4, and is finally dispersed in the water. When crystals appear on the inner wall of the connecting pipe 4, the upper winding assembly 5 and the lower winding assembly 8 are started. When the upper winding assembly 5 is running, the upper rope body 501 is wound up, and at the same time, the lower winding assembly 8 is running, and the lower rope body 801 is released, so that the cleaning roller 7 moves vertically upward. At this time, the cleaning roller 7 first detaches from the storage tube 6 and then enters the connecting pipe 4. When the cleaning roller 7 moves upward inside the connecting pipe 4, the edge scrapes off the crystals attached to the inner wall. When the cleaning is completed, the upper winding assembly 5 and the lower winding assembly 8 are started again. At this time, the upper winding assembly 5 releases the upper rope body 501, and the lower winding assembly 8 rewinds the lower rope body 801, thereby pulling the cleaning roller 7 to move vertically downward, so that the cleaning roller 7 is reinserted into the storage tube 6;

[0041] By arranging the connecting tube 4, the upper winding assembly 5, the storage tube 6, the lower winding assembly 8 and the cleaning roller 7, the upper winding assembly 5 and the lower winding assembly 8 are used to control the cleaning roller 7 to enter the connecting tube 4 and move vertically, so as to scrape off the crystals attached to the inner wall of the connecting tube 4, thereby avoiding the blockage of the connecting tube 4. After the cleaning is completed, the cleaning roller 7 is stored in the storage tube 6 on the water pipe 2, which will not affect the normal output efficiency of the disinfectant, will not come into contact with the disinfectant outside the cleaning work, will not produce crystals itself, has a long service life, and is easy to maintain.

[0042] Example 2: See Figure 1 , Figure 3 and Figure 4 , which is different from the above embodiment, the upper winding assembly 5 includes an upper shell cover 502 fixed to the top of the connecting tube 4, the side wall of the upper shell cover 502 is fixedly connected to the upper drive motor 503, the output shaft of the upper drive motor 503 is fixedly connected to the upper shaft body 504, the upper shaft body 504 extends to the inside of the upper shell cover 502 and is rotatably connected to the side wall of the upper shell cover 502, an upper winding wheel 505 is fixed on the upper shaft body 504, and the top of the upper rope body 501 is connected to the upper winding wheel 505 is fixed, the lower winding assembly 8 includes a lower shell cover 802 fixed to the bottom end of the storage tube 6, the side wall of the lower shell cover 802 is fixedly connected to a lower driving motor 803, the output shaft of the lower driving motor 803 is fixedly connected to a lower shaft body 804, the lower shaft body 804 extends to the inside of the lower shell cover 802 and is rotatably connected to the side wall of the lower shell cover 802, a lower winding wheel 805 is fixed on the lower shaft body 804, and the bottom end of the lower rope body 801 is fixed to the lower winding wheel 805;

[0043] The upper drive motor 503 and the lower drive motor 803 are both configured as servo motors, the upper shell cover 502 and the lower shell cover 802 are both fixedly installed by bolts, and the connection between the upper shaft body 504 and the upper shell cover 502 and the connection between the lower shaft body 804 and the lower shell cover 802 are both sealed;

[0044] When in use, the upper drive motor 503 is started, and the upper drive motor 503 drives the upper shaft body 504 and the upper winding wheel 505 to rotate, thereby realizing the winding of the upper rope body 501, and the lower drive motor 803 is started to drive the lower shaft body 804 and the lower winding wheel 805 to rotate, thereby unwinding the lower rope body 801, and the cleaning roller 7 can be driven to move vertically upward by mutual cooperation, and similarly, the upper drive motor 503 and the lower drive motor 803 can drive the cleaning roller 7 to move vertically downward by reverse operation;

[0045] By providing the upper driving motor 503 and the lower driving motor 803 , it is advantageous to drive the cleaning roller 7 to move vertically by retracting and releasing the upper rope body 501 and the lower rope body 801 , and the degree of automation is high.

[0046] Example 3, see Figure 4-Figure 6, which is different from the above embodiment, the cleaning roller 7 includes an inner cleaning column 701 and an outer cleaning tube 702, the outer cleaning tube 702 is sleeved outside the inner cleaning column 701, the outer diameter of the outer cleaning tube 702 matches the inner diameter of the connecting tube 4, the outer cleaning tube 702 is engaged with the inner cleaning column 701, and a control component 9 is provided on the lower shell cover 802, the control component 9 is used to release the engagement connection between the outer cleaning tube 702 and the inner cleaning column 701, the inner wall of the outer cleaning tube 702 is provided with an annular limiting groove 703, the inner wall of the inner cleaning column 701 A cavity 704 is provided, in which a limit pin 705 is provided, one end of the limit pin 705 is provided with an arc end 706, the other end of the limit pin 705 is movably plugged with the side wall of the cavity 704, a base ring 707 is fixedly sleeved on the outside of the limit pin 705, a spring 708 is fixed between the base ring 707 and the side wall of the cavity 704, the spring 708 is sleeved on the outside of the limit pin 705, a guide rod 709 is fixed in the center of the cavity 704, a driving block 710 is sleeved on the guide rod 709, and the bottom end of the outer cleaning tube 702 is fixed A ring iron block 711 is connected, a magnet 712 is provided at the bottom of the inner cavity of the storage tube 6, and the magnet 712 is fixedly connected to the lower shell cover 802. The top of the driving block 710 is provided with an annular slope 713, and the side wall of the driving block 710 is provided with an annular shallow groove 714, and the inner wall of the annular shallow groove 714 is set as an arc surface. A vertical rod 715 is fixed at the bottom end of the driving block 710, and the vertical rod 715 is movably plugged with the inner bottom wall of the cavity 704 and extends to the bottom of the inner cleaning column 701. The bottom end of the vertical rod 715 is fixedly connected with an annular plate 716, and the annular plate 716 is fixedly connected to the bottom of the inner cleaning column 701. 16 is sleeved on the outside of the lower rope body 801, the control assembly 9 includes an electric push rod 91 and a base shaft 92, the base shaft 92 is arranged inside the lower shell cover 802 and is rotatably connected to the side wall of the lower shell cover 802, a push block 93 is fixedly connected to the middle of the base shaft 92, one end of the base shaft 92 extends to the outside of the lower shell and is fixedly connected to a gear 94, the electric push rod 91 is fixed to the outside of the lower shell cover 802, a rack 95 is fixed to the output end of the electric push rod 91, the rack 95 is meshed with the gear 94, and the rack 95 is also slidably connected to the outer wall of the lower shell cover 802;

[0047] Among them, the upper rope body 501 and the lower rope body 801 are fixed to the top and bottom ends of the inner cleaning column 701 respectively, the inner cleaning column 701 is set to a cylindrical shape, the outer cleaning tube 702 is set to a circular tube shape, and the limit pin 705 is preferably set to two, and the two limit pins 705 are symmetrically distributed on both sides of the inner cleaning column 701. In the initial state, the limit pin 705 is inserted into the annular limit groove 703 at one end away from the arc surface end 706, and the arc surface end 706 is located in the annular shallow groove 714. The spring 708 is in a compressed state, thereby realizing the snap connection, and the vertical rod 715 is preferably set to two and symmetrically distributed. The annular plate 716 is arranged horizontally, the bottom ends of the two vertical rods 715 are fixedly connected to the annular plate 716, and a through hole corresponding to the position of the storage tube 6 is arranged on the lower shell cover 802, the diameter of the through hole is smaller than the diameter of the inner cleaning column 701 and larger than the diameter of the annular plate 716, when the cleaning roller 7 is stored in the storage tube 6, the annular iron block 711 just corresponds to the position of the magnet 712 and is adsorbed by the magnet 712, and at this time the annular plate 716 extends to the inside of the lower shell cover 802 through the through hole, and the base shaft 92 and the push block 93 on the base shaft 92 are just located at the edge of the annular plate 716;

[0048] When in use, when the upper rope body 501 pulls the inner cleaning column 701, since the inner cleaning column 701 is engaged with the outer cleaning tube 702, the outer cleaning tube 702 and the inner cleaning column 701 move up together, and the annular iron block 711 moves up with the outer cleaning tube 702 to separate it from the magnet 712. When there are many crystals inside the connecting tube 4, the resistance to scraping the crystals through the entire cleaning roller 7 is often large, which not only increases the difficulty of cleaning, but also makes it easy for the large amount of crystals under cleaning to completely block the inside of the connecting tube 4. At this time, the electric push rod 91 is started, and the electric push rod 91 extends to drive the rack 95 to move, and the rack 9 The driving gear 94 and the base shaft 92 rotate, and the base shaft 92 drives the push block 93 to swing. When the push block 93 swings, it pushes the annular plate 716 on the side downward, so that the annular plate 716 moves downward. When the annular plate 716 moves downward, it drives the vertical rod 715 and the driving block 710 to move downward. When the driving block 710 moves downward, the arc surface end 706 at the end of the limit pin 705 is separated from the annular shallow groove 714. At this time, under the elastic force of the spring 708, the limit pin 705 shrinks inward and is separated from the annular limit groove 703, thereby releasing the clamping connection between the inner cleaning column 701 and the outer cleaning tube 702. When the upper winding assembly 5 and the lower winding assembly 8 are started, only the inner cleaning column 701 can be driven to move upward. Since the inner cleaning column 701 has a smaller diameter, it can first clean a part of the crystals in the connecting tube 4. After the inner cleaning column 701 is cleaned, it moves back to the outer cleaning tube 702. At this time, the electric push rod 91 is started again. The electric push rod 91 contracts and drives the rack 95 to move in the opposite direction. The rack 95 drives the base shaft 92 and the swing block to swing in the opposite direction. When the push block 93 swings, it just pushes the annular plate 716 on the side upward. The annular plate 716 moves upward and drives the vertical rod 715 and the driving block 710 to move upward. When the driving block 710 moves upward, the annular slope 713 squeezes the arc surface end 706, thereby pushing the limiting pin 705 to move outward and compressing the spring 708. After the limiting pin 705 moves outward, it is re-engaged in the annular limiting groove 703, and the driving block 710 moves upward until the annular shallow groove 714 matches the arc surface end 706. The elastic force of the spring 708 makes the arc surface end 706 fit inside the annular shallow groove 714. At this time, the upper winding assembly 5 and the lower winding assembly 8 are started again, which can drive the entire cleaning roller 7 to move upward at the same time, and perform secondary cleaning on the remaining crystals in the connecting pipe 4;

[0049] By setting the cleaning roller 7 to have an inner cleaning column 701 and an outer cleaning tube 702 with different outer diameters, and being able to connect and separate by snapping, when faced with a situation where there are a lot of crystals in the connecting tube 4, first use the inner cleaning column 701 with a smaller diameter for preliminary cleaning, and then use the outer cleaning tube 702 with a larger diameter for secondary cleaning. This batch cleaning reduces the difficulty of cleaning, and can also reduce the probability of crystals clogging the connecting tube 4 during the cleaning process, which is more practical and efficient.

[0050] Example 4, see Figure 1 , Figure 8 and Fig. 9 , which is different from the above embodiment, a drainage blocking valve 10 is installed on the water pipe 2, a water inlet blocking valve 11 is installed on the output pipe 3, a drainage branch pipe 12 is fixedly connected to the output pipe 3, the drainage branch pipe 12 is fixedly connected to the water pipe 2 at one end away from the output pipe 3, a first gate valve 13 is installed at one end of the drainage branch pipe 12 close to the output pipe 3, a second gate valve 14 is installed at one end of the drainage branch pipe 12 close to the water pipe 2, and a filter 15 is fixed in the middle of the drainage branch pipe 12;

[0051] The drain blocking valve 10 is arranged on the drainage direction side of the connecting pipe 4, the connection between the drain branch pipe 12 and the water pipe 2 is arranged on the drainage direction side of the drain blocking valve 10, the connection point between the drain branch pipe 12 and the output pipe 3 is located between the connecting pipe 4 and the water inlet blocking valve 11, and the filter 15 includes an external shell and a filter element installed inside the shell;

[0052] When in use, after the crystals are scraped off by the cleaning roller 7, the drainage blocking valve 10 and the water inlet blocking valve 11 are closed, and the first gate valve 13 and the second gate valve 14 are opened. At this time, the water and the crystals in the water pipe 2 will enter the drainage branch pipe 12 through the connecting pipe 4 and the output pipe 3, wherein the crystals are filtered and collected by the filter 15, and the water is discharged into the water pipe 2 again;

[0053] By setting up a drainage branch pipe 12, a filter 15, a drainage blocking valve 10, a water inlet blocking valve 11, a first gate valve 13 and a second gate valve 14, it is helpful to control the direction of water flow in the water pipe 2, transport the cleaned and detached crystals to the filter 15, and then collect the crystals to prevent the crystals from mixing into the water in the water pipe 2 and causing pollution.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
