[0035] The fixing assembly 5 facilitates fixing the fixing member 6 and the connecting member 7 in the water distributor body 1;

[0036] Filters 8 are fixedly mounted on the inner side walls of the fixing member 6 and the connecting member 7. Gravel is provided on the inner side of the fixing member 6 and the connecting member 7. The gravel is located in the middle of the two filter screens 8.

[0037] A protective component 10 is provided on the outer side wall of the water distributor body 1;

[0038] Water is injected into the water distributor body 1 through the water inlet 9, and then the water is filtered by the sand-proof component 4 inside the water distributor body 1. During the filtering, the sealing and protection effect can be improved by the protection component 10, thereby preventing water penetration and the like, and avoiding friction and the like due to direct contact between the water distributor body 1 and objects, thereby improving the protection effect. When water flows through the upper joint 2 or the lower joint 3, the water is filtered by the filter mesh 8 and gravel inside the fixing member 6 and the connecting member 7, thereby improving the sand-proof effect, thereby avoiding the impact on water use due to the presence of sand and gravel in the water.

[0039] In this embodiment, specifically, the sand control assembly 4 includes two filter cartridges 41 provided on the inner side wall of the water distributor body 1. The two filter cartridges 41 are plugged into each other, and a gravel layer 42 is provided between the two filter cartridges 41.

[0040] By manually rotating the threaded bolt 11 on the water distributor body 1 and making one end of it press against the filter cartridge 41, the filter cartridge 41 can be stably fixed in the water distributor body 1, and the filter cartridge 41, with the cooperation of the gravel layer 42, can effectively prevent sand and gravel from entering the water distributor body 1. Conversely, manually reverse the bolt 11 so that one end of it is away from the filter cartridge 41, making it convenient to remove the filter cartridge 41 from the water distributor body 1, and thus convenient for cleaning and replacement.

[0041] In this embodiment, specifically, the protective assembly 10 includes a first protective shell 101 and a second protective shell 102 fixedly mounted on the water distributor body 1 by screws. The first protective shell 101 and the second protective shell 102 are arranged opposite to each other on the left and right.

An annular plate 104 is fixedly mounted at one end of the first protective shell 101, and the annular plate 104 is plugged into the annular groove 103.

[0042] By manually putting the first protective shell 101 and the second protective shell 102 on the water distributor body 1 and plugging the annular plate 104 at one end of the first protective shell 101 into the annular groove 103 opened at one end of the second protective shell 102, the connection sealing effect of the first protective shell 101 and the second protective shell 102 can be ensured. Then, the first protective shell 101 and the second protective shell 102 are fixed to the water distributor body 1 by screws, so that the first protective shell 101 and the second protective shell 102 can prevent and protect the water penetrating between the water distributor body 1 and the bolt 11, thereby preventing water from penetrating and affecting the use of surrounding equipment, and avoiding friction between the water distributor body 1 and objects due to direct contact, which is beneficial to improving the protection effect.

[0043] In this embodiment, specifically, a sealing ring is provided inside the annular groove 103, and the sealing ring is located between the second protective shell 102 and the annular plate 104. A protective pad 105 is fixedly installed on the inner side walls of the first protective shell 101 and the second protective shell 102. The material of the protective pad 105 is rubber, and the inner side wall of the protective pad 105 is in contact with the water distributor body 1;

[0044] The sealing ring is used to improve the plug-in sealing effect between the annular plate 104 and the annular groove 103, and the rubber protective pad 105 is used to improve the sealing protection effect between the first protective shell 101, the second protective shell 102 and the water distributor body 1, thereby effectively avoiding water seepage.

[0045] In this embodiment, specifically, the fixing assembly 5 includes a first curved plate 51 and a second curved plate 53 provided inside the water distributor body 1. The first curved plate 51 and the second curved plate 53 are arranged opposite to each other up and down, and the fixing member 6 and the connecting member 7 are locked and fixed between the first curved plate 51 and the screw 52 by screws. The screw 52 is fixedly installed on the inner side wall of the first curved plate 51, and the inner side wall of the second curved plate 53 is movably connected to an internal threaded barrel 54, and the bottom of the internal threaded barrel 54 is threadedly connected to the screw 52;

[0046] The first curved plate 51 and the screw 52 are manually placed into the water distributor body 1, and then the internal threaded barrel 54 mounted on the bearing of the second curved plate 53 is manually rotated, so that the internal threaded barrel 54 can drive the first curved plate 51 and the second curved plate 53 to move away from each other through the screw 52 threadedly connected thereto, so that the first curved plate 51 and the second curved plate 53 can be fixed in the water distributor body 1 under the action of the screw 52 and the internal threaded barrel 54, and finally the fixing part 6 and the connecting part 7 can be fixed to the fixing assembly 5 by screws, so that the filter screen 8 and gravel inside the fixing part 6 and the connecting part 7 can filter the water, and the fixing part 6, the connecting part 7 and the filter screen 8 can be easily disassembled, cleaned and replaced in the later stage.

[0047] In this embodiment, specifically, a connecting pipe 12 is fixedly mounted on the inner side wall of the first curved plate 51, and a hollow pipe 13 is fixedly mounted on the inner side wall of the second curved plate 53. The bottom of the hollow pipe 13 is plugged into the connecting pipe 12.

[0048] By connecting the tube 12 and the hollow tube 13, the first curved plate 51 and the second curved plate 53 in motion can be limited, thereby preventing the internal threaded tube 54 from driving the first curved plate 51 and the second curved plate 53 away from each other when they are fixed with the cooperation of the screw 52, and thus preventing the first curved plate 51 or the second curved plate 53 from rotating together with the internal threaded tube 54 or the screw 52, thereby avoiding affecting the fixation of the fixing member 6 and the connecting member 7 in the later stage.

[0049] The working principle and usage process of the present invention are as follows: when in use, the water entering from the water inlet 9 is filtered through the sand control component 4, and then when water passes through the upper joint 2 or the lower joint 3, the water passing through is filtered by the filter mesh 8 and gravel inside the fixing member 6 and the connecting member 7, thereby improving the sand control effect, and then through the protective component 10, it can prevent water infiltration and the like from occurring in the device, and can also avoid friction and the like due to direct contact between the water distributor body 1 and the object, thereby improving the protection effect. When replacing, manually unscrew the screws on the fixing component 5, the fixing member 6 and the connecting member 7, so that the fixing member 6 and the connecting member 7 can be removed from the fixing component 5 and the water distributor body 1, and then manually remove the fixing components 5 on both sides of the sand control component 4, and then reverse the bolt 11 so that one end thereof is away from the sand control component 4, thereby facilitating the removal of the sand control component 4 from the water distributor body 1, and facilitating cleaning and replacement.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
