Description

Technical Field

[0001] The utility model relates to the technical field of water quality improvement, in particular to a drainage mechanism of water quality improvement equipment. Background Art

[0002] The physical properties of river water mainly refer to water temperature, color, transparency and smell. The chemical properties are determined by the gases, ions, molecules, colloids, suspended solids, microorganisms and the content of these substances dissolved and dispersed in the river water. The main chemical components dissolved in river water are similar to those of general natural water, and its evaluation indicators are also the same as those of natural water. The existing river water quality improvement equipment has a relatively complex structure. At the same time, when dealing with the impurities filtered out, it is troublesome to use manual salvage. At the same time, it is impossible to adjust the discharge volume, resulting in poor water quality improvement.

[0003] Chinese patent CN213475562U discloses a river water quality improvement device, which can filter and purify river water and adjust the amount of drainage through the coordinated use of a box, a first filter, activated carbon, a horizontal plate, a drain pipe, a baffle and a second filter.

[0004] However, when this solution is in use, the drainage volume is changed by the rotation of the baffle inside the drain pipe. However, when the drainage volume is not at the minimum or maximum value, the baffle will not be continuously impacted by the water flow. After long-term operation, the baffle may rotate abnormally, causing the drainage volume of the drain pipe to change, causing the total drainage volume to deviate from the rated value. Utility Model Content

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a drainage mechanism of a water quality improvement equipment includes a drainage pipe 2 connected to a frame 1 and a fixed ring 3 arranged inside the frame 1, a movable ring 21 is movably sleeved on the drainage pipe 2, a stepped through hole 11 connected to the drainage pipe 2 is opened on the frame 1, the fixed ring 3 is coaxial with the drainage pipe 2, the fixed ring 3 is inside the stepped through hole 11, the center of the fixed ring 3 is hollowed out and the two ends of the fixed ring 3 are connected by a rotating shaft 31, the rotating shaft 31 is parallel to the axis of the fixed ring 3, the number of the rotating shafts 31 is four, the four rotating shafts 31 are evenly distributed around the axis of the fixed ring 3, a blocking piece 32 is fixedly arranged on the rotating shaft 31, and when the movable ring 21 and the drainage pipe 2 move relative to each other, the rotating shaft 31 rotates to drive the blocking piece 32 to block the drainage pipe 2.

[0027] When the drainage volume is large, the movable ring 21 is controlled to move relative to the drain pipe 2, and the rotating shaft 31 drives the blocking piece 32 to rotate and move to the outside of the fixed ring 3. At this time, the drain pipe 2 is not blocked. When the drainage volume needs to be reduced, the movable ring 21 is controlled to move relative to the drain pipe 2 again. At this time, the rotating shaft 31 rotates to drive the blocking piece 32 to continuously move to the inside of the fixed ring 3, and the drain pipe 2 will be continuously blocked at this time. Compared with the prior art, the blocking piece 32 of the utility model blocks the drain pipe 2 while maintaining a vertical state with the water flow direction, so that the drainage volume of the drain pipe 2 will not change due to the influence of the working environment, ensuring that the drainage volume of the drain pipe 2 will not deviate due to too long time, and ensuring that the entire water quality improvement equipment can work stably.

[0028] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown: the drain pipe 2 also includes an inner gear ring 22 and a gear 23. The inner gear ring 22 is coaxially rotatably sleeved on one end of the drain pipe 2 close to the fixed ring 3. The outer diameter of the inner gear ring 22 is equal to the outer diameter of the drain pipe 2. The gear 23 is rotatably set inside the side wall of the drain pipe 2. The axis of the gear 23 is parallel to the axis of the drain pipe 2. The gear 23 meshes with the inner gear ring 22. A prism 24 extending to the outside of the drain pipe 2 is coaxially fixed on the gear 23. A first groove 311 for inserting the prism 24 is provided on the rotating shaft 31. A fixing strip 25 is fixedly provided on the outer wall of the inner gear ring 22. A second groove 211 for inserting the fixing strip 25 is provided on the inner wall of the movable ring 21.

[0029] The movable ring 21 is controlled to rotate. The movable ring 21 rotates the inner gear ring 22 through the cooperation of the second groove 211 and the fixed bar 25. The inner gear ring 22 rotates and drives the gear 23 to rotate. The gear 23 rotates by the cooperation of the first groove 311 and the prism 24 so that the rotating shaft 31 drives the baffle 32 to rotate. Compared with the prior art, the inner gear ring 22 of the utility model drives four gears 23 to rotate at the same time, thereby ensuring that all the baffles 32 maintain synchronization of movement.

[0030] See also Figure 2-Figure 6 As shown: an external thread is arranged on the outer wall of the drain pipe 2, and an internal thread matching with the external thread is arranged on the inner wall of the movable ring 21.

[0031] The movable ring 21 is rotated, and the movable ring 21 slides relative to the drain pipe 2 under the condition of threaded cooperation. At the same time, the inner gear ring 22 also rotates under the cooperation of the fixing bar 25 and the second groove 211. Compared with the prior art, the movable ring 21 of the utility model is threadedly cooperated with the drain pipe 2, so that the position of the baffle 32 after moving can be fixed.

[0032] See also Figure 4-Figure 6 As shown: the external thread on the drain pipe 2 is not at both ends.

[0033] Compared with the prior art, the drain pipe 2 of the present invention limits the position of the external thread, thereby ensuring that the movable ring 21 will not separate from the drain pipe 2 when rotating.

[0034] See also Figure 6 As shown, an anti-slip strip 212 is fixedly provided on the outer side wall of the movable ring 21 . There are several anti-slip strips 212 , and all the anti-slip strips 212 are evenly distributed around the axis of the movable ring 21 .

[0035] Compared with the prior art, the movable ring 21 of the utility model is provided with an anti-slip strip 212 for increasing friction, thereby facilitating the user to control the movable ring 21 to move in the water flow.

[0036] See also Figure 3-Figure 6 As shown, a first clamping groove 33 is provided on the side wall of the fixing ring 3 , and a clamping protrusion 12 cooperating with the first clamping groove 33 is fixedly provided inside the stepped through hole 11 .

[0037] First, retract all the blocking pieces 32 into the interior of the fixing ring 3, then align the first snap-fit ​​groove 33 with the snap-fit ​​protrusion 12, and then insert the fixing ring 3 into the interior of the stepped through hole 11. Compared with the prior art, the first snap-fit ​​groove 33 and the snap-fit ​​protrusion 12 of the utility model cooperate to limit the position of the fixing ring 3 in the stepped through hole 11, thereby ensuring that the fixing ring 3 itself does not rotate.

[0038] See also Figure 3-Figure 6 As shown: a second clamping groove 26 cooperating with the clamping protrusion 12 is provided on the drain pipe 2.

[0039] Align the second snap-fit ​​groove 26 and the snap-fit ​​protrusion 12, and then connect the drain pipe 2 to the stepped through hole 11. Compared with the prior art, the second snap-fit ​​groove 26 and the snap-fit ​​protrusion 12 of the utility model cooperate to limit the position of the drain pipe 2, thereby ensuring that the prism 24 can be inserted into the first groove 311.

[0040] See also Figure 3-Figure 6 As shown: a clamping strip 27 is slidably provided at one end of the drain pipe 2 close to the fixing ring 3, the sliding direction of the clamping strip 27 is parallel to the diameter direction of the drain pipe 2, a spring 28 is fixedly provided at one end of the clamping strip 27 close to the center of the drain pipe 2, the other end of the spring 28 extends along the sliding direction of the clamping strip 27, and a clamping hole 13 cooperating with the clamping strip 27 is opened in the stepped through hole 11.

[0041] Insert the clamping strip 27 into the wall of the drain pipe 2, and then insert the drain pipe 2 into the stepped through hole 11. The spring 28 releases its elastic force to push the clamping strip 27 into the clamping hole 13. Compared with the prior art, the clamping strip 27 and the clamping hole 13 of the utility model cooperate to fix the position of the drain pipe 2, thereby facilitating the installation of the drain pipe 2.

[0042] The above embodiments only express one or several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
