In particular, the functionality of clean water storage equipment is more sufficient and complete than that of sewage storage equipment. The existing clean water storage equipment is mainly represented by a water outlet trough, but the water outlet trough is also equipped with a water inlet device, a water outlet device, a water quality detection device, a water quality treatment device, etc., among which the water outlet device is represented by a water outlet valve.

[0003] The existing outlet valve on the clean water storage tank will freeze in low temperature conditions in winter because the clean water stored in the clean water storage tank will freeze, and the valve group will also freeze in the clean water, causing the valve group to move insensitively after freezing, and the water output may not meet the discharge standards; and the existing water storage valve guide column cannot ensure the parallelism of the four guide columns during installation, resulting in the spring being stuck by the guide column when the water outlet valve is opened, the spring loses its effect, and the valve plate cannot be opened; and the existing valve plate has a short maintenance cycle, and the spring must be checked frequently to see if it has failed, wasting manpower. To this end, we provide a clean water storage tank outlet device to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0029] See also Figure 1-3 The utility model is a water outlet device for a clean water storage tank, comprising a main shaft 2, which is connected to a valve group 1 through a cam 3, and is also connected to a reducer 6 through a sprocket 2 7. Under the power provided by the reducer 6 and the linkage effect of the sprocket 1 4 and the sprocket 2 7, all valve groups 1 can be opened or closed uniformly to achieve the effect of opening water outlet and sealing flow blocking.

[0030] Specifically, two groups of main shafts 2 and valve groups 1 are respectively provided, and the two main shafts 2 are connected by a coupling 8. Multiple cams 3 are arranged at equal intervals on one main shaft 2, and a valve group 1 is also arranged behind the cam 3. The other ends of the two main shafts 2 are rotatably connected to the inner wall of the water storage tank 11 through bearings 9. At the same time, a sprocket 2 7 is sleeved on one main shaft 2, and a sprocket 1 4 is sleeved on the shaft end of the reducer 6. The sprocket 1 4 and the sprocket 2 7 are synchronously rotated and connected through a chain 5.

[0031] Furthermore, a water outlet 10 is provided at the bottom of the water tank 11, and a mounting frame 12 is installed at the bottom of the water tank 11. The mounting frame 12 is installed on the concrete wall 14 through expansion bolts 13, and a slag retaining plate 15 is also installed on the outer wall of the water tank 11 corresponding to the front end of the valve body 1, and the cam 3 and the valve group 1 are arranged one by one.

[0032] The operation process of this embodiment is: the reducer 6 works to provide the sprocket 1 4 on its shaft end with the power for rotation. At that time, the sprocket 1 4 will drive the sprocket 2 7 on the main shaft 2 to rotate synchronously under the interlocking action of the chain 5, that is, the main shaft 2 will also rotate, causing the cam 3 on the main shaft 2 to rotate as well. Moreover, due to the shape of the cam 3 itself, when it rotates, the cam 3 itself will press on the wear-resistant plate 109, causing the valve plate 108 to close. After the cam 3 is turned open, the valve plate 108 automatically opens under the action of the torsion spring 104, so that the running trajectory of the valve plate 108 can be controlled by the cam 3 to ensure that the valve plate 108 is closed in place to avoid water leakage. Specific embodiment 2

[0034] See also Figure 4-5On the basis of the specific embodiment 1, a valve group 1 is further provided, wherein a large O-ring 113 is installed on the valve plate 108 on the valve group 1, and a small O-ring 112 is also installed between the valve plate 108 and the wear-resistant plate 109. The large O-ring 113 and the small O-ring 112 can prevent water leakage caused by uneven plate surface of the water storage tank 11.

[0035] Specifically, the fixed ear plate 101 and the valve plate 108 assembly are fixed on the water tank 11 after the pin is inserted, and a fixing frame 102 is also installed on the inner wall of the water tank 11 corresponding to the two fixed ear plates 101, and a torsion spring upper fixing block 103 is also installed on the fixing frame 102. The fixing frame 102 is connected to the torsion spring 104 through the torsion spring upper fixing block 103, and the middle part of the torsion spring 104 is connected to the pin 106 through the cotter pin 105, and the torsion spring lower fixing blocks 107 are also installed on the two end feet of the torsion spring 104, and the torsion spring 104 is connected to the valve plate 108 through the torsion spring lower fixing block 107.

[0036] Furthermore, a large O-ring 113 is embedded and sleeved on the valve plate 108, and a wear-resistant plate 109 is provided on the front side of the valve plate 108, and a small O-ring 112 is installed on the side of the wear-resistant plate 109 facing the valve plate 108. At the same time, a valve plate fixing sleeve 115 is installed on the top axial end of the valve plate 108, and the valve plate fixing sleeve 115 is connected to the middle part of the pin shaft 106. An ear plate fixing bolt 110 is inserted into the fixed ear plate 101, and the fixed ear plate 101 is connected to the inner wall of the water tank 11 through the ear plate fixing bolt, and a wear plate fixing bolt 111 is inserted into the wear plate 109, and the wear plate 109 is connected to the large O-ring 113 and the small O-ring 112 through the wear plate fixing bolt 111, and a self-locking nut 114 is locked and connected to the other end of the wear plate fixing bolt 111. Specific embodiment three

[0038] See also Figure 6 , and also provides a structure of a water outlet valve on an existing clean water outlet tank.

[0039] Specifically, an old fixed plate is fixedly installed at the water outlet position on the water storage tank 11, a new fixed plate is arranged on the front side of the old fixed plate, and a guide column is arranged between the old fixed plate and the new fixed plate, and one end of the guide column is detachably fixedly connected to the old fixed plate, and the outer side wall of the guide column is slidably plugged into the new fixed plate.

[0040] Furthermore, a spring is sleeved on the guide column, and the spring is arranged between the old fixing plate and the new fixing plate. At the same time, the two ends of the spring are respectively connected to the front side wall of the old fixing plate and the rear side wall of the new fixing plate.

[0041] The operation process of this embodiment is as follows: first, by applying an outward traction force to the new fixing plate, the spring is stretched, and then, under the action of its own elastic force, the new fixing plate is separated from the old fixing plate, that is, a gap is generated between the two, and the gap can be used for the outflow of clean water; second, under the action of external force, the new fixing plate is attached to the old fixing plate, and the spring is in a compressed state in this state, and then this part of the external force is removed, and then the spring returns to its initial state, that is, extension, and it will push the new fixing plate to move away from the old fixing plate. A gap is generated between the two, and water can flow. However, in a winter environment, because the surrounding environment is in a low temperature state, the spring will be frozen on the guide column in extremely cold weather, making the spring inactive, resulting in the movable plate being unable to move, the valve port being unable to close, and water leaking.
