[0016] 2. In this utility model, by setting a sealing device, the plug ring is inserted into the plug groove, which causes the plug ring to squeeze the sealing ring, causing the sealing ring to move to one side and squeeze the third spring. The third spring contracts and generates a rebound force, which causes the third spring to drive the sealing ring to fit tightly against one side of the plug ring, thereby sealing the gap between the external pipe and the water outlet pipe, thus improving the sealing performance and preventing water leakage from affecting the use.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example 1

[0022] Reference Figures 1-3This is the first embodiment of the present invention. This embodiment provides a wastewater zero-discharge evaporation circulation pump mechanical device, including a base frame 2, a drive motor 1 mounted on the top of the base frame 2, and a base block 3 connected to the top of the base frame 2. The pump body 10 is connected to the top of the base block 3. The output shaft of the drive motor 1 is connected to a fan wheel of the pump body 10. An inlet pipe 4 is connected to the outer wall of the pump body 10, and an outlet pipe 9 is connected to one side of the pump body 10. A buffer device 6 is connected to the top of the inlet pipe 4. The buffer device 6 includes a support pipe 601 connected to the inlet pipe 4, and a sliding part is provided inside the inlet pipe 601. A buffer plate 606 buffers the water flow through damping movement. A support ring 607 is connected to the inner wall of the support pipe 601. Multiple side grooves 610 are opened on the inner wall of the support ring 607. A bracket 602 is connected to the inner wall of the side grooves 610. The same support rod 603 is connected between the inner walls of the brackets 602. A sliding ring 604 is slidably connected to the outer wall of the support rod 603. A connecting plate 605 is slidably connected to the outer wall of the sliding ring 604. The multiple connecting plates 605 are connected to the same buffer plate 606. Two first springs 609 are sleeved on the outer wall of the support rod 603.

[0023] Furthermore, the bottom of the support pipe 601 is connected to the top of the water inlet pipe 4 by bolts, and multiple dispersion holes are provided in the buffer plate 606.

[0024] Furthermore, the upper first spring 609 is connected at both ends to the top of the sliding ring 604 and the top of the inner wall of the bracket 602, respectively, and the lower first spring 609 is connected at both ends to the bottom of the sliding ring 604 and the bottom of the inner wall of the bracket 602, respectively.

[0025] Furthermore, a shielding device 7 is connected to one side of the bracket 602. The shielding device 7 includes a protective frame 701. A movable groove 705 is opened on one side of the protective frame 701. Multiple shielding blocks 702 are slidably connected in the movable groove 705. Adjacent shielding blocks 702 are attached to each other and slidably connected. A second spring 704 is connected to one side of the shielding block 702.

[0026] Furthermore, one side of the protective frame 701 is connected to the inner wall of the bracket 602, and both sides of the shielding block 702 are provided with inclined surfaces, and the other end of the second spring 704 is connected to one side of the inner wall of the movable groove 705.

[0027] Furthermore, a fixing groove is provided on one side of the blocking block 702, and a fixing rod 703 is slidably connected in the fixing groove. The other end of the fixing rod 703 is connected to one side of the inner wall of the movable groove 705, and the second spring 704 is sleeved on the outside of the fixing rod 703.

[0028] Furthermore, both sides of the connecting plate 605 are connected to top blocks 608, and the top of the top block 608 is provided with two extrusion slopes.

[0029] The specific implementation method is as follows: By setting up a buffer device 6, water flow is introduced through the inlet pipe 4, allowing the water flow to directly contact the top of the buffer plate 606. The impact causes the buffer plate 606 to move downwards, which in turn causes the connecting plate 605 to move downwards. The connecting plate 605 then moves the sliding ring 604. The sliding ring 604 slides on the outer wall of the support rod 603, causing the first springs 609 on both sides of the sliding ring 604 to stretch and compress respectively. This allows the first springs 609 to absorb the impact force of the water flow through extension, thereby preventing the water flow from directly entering the pump body 10 and impacting the fan wheel, which could damage the fan wheel. When the connecting plate 605 moves up and down, it causes the top block 608 to press against the inclined part of the blocking block 702. This causes the blocking block 702 to move inward and compress the second spring 704. The compressed second spring 704, through its rebound force, causes the blocking block 702 to close the path that the connecting plate 605 has moved, preventing large impurities in the water from adhering to the outer wall of the support rod, thus avoiding affecting the sliding of the sliding ring 604. The second spring 704 is supported by the fixed rod 703 to prevent the second spring 704 from bending during compression and affecting the rebound effect. Example 2

[0030] Reference Figure 4 In the second embodiment of this utility model, an external pipe 5 is installed on one side of the water outlet pipe 9, and a sealing device 8 is provided between the water outlet pipe 9 and the external pipe 5. The sealing device 8 includes a plug groove 801, which is opened on the side wall of the water outlet pipe 9. A sealing ring 804 is slidably connected to the inner wall of the plug groove 801. A third spring 802 is connected to one side of the sealing ring 804, and the other end of the third spring 802 is connected to one side of the inner wall of the plug groove 801.

[0031] Furthermore, a plug ring 805 is attached to one side of the sealing ring 804. The outer wall of the plug ring 805 is attached to and slidably connected to the inner wall of the plug groove 801. One side of the plug ring 805 is connected to one side of the outer pipe 5. Two rubber rings 806 are connected to the outer wall of the plug ring 805.

[0032] Furthermore, the inner wall of the insertion groove 801 is provided with multiple limiting grooves, and a limiting block 803 is slidably connected in the limiting groove. One side of the limiting block 803 is connected to the outer wall of the sealing ring 804.

[0033] The specific implementation method is as follows: By setting a sealing device 8, the insertion ring 805 is inserted into the insertion groove 801. The movement of the insertion ring 805 causes one side to squeeze the sealing ring 804. The sealed ring 804 under force moves to one side and squeezes the third spring 802, causing the third spring 802 to contract and generate a rebound force. When the outer pipe 5 is installed in place, the rebound force of the third spring 802 causes the sealing ring 804 to fit tightly against one side of the insertion ring 805, thereby sealing the gap between the outer pipe 5 and the water outlet pipe 9 to prevent water leakage from affecting use. By setting a rubber ring 806, the flexibility of the rubber ring 806 allows the rubber ring 806 to seal the gap between the insertion groove 801 and the insertion ring 805, thereby further improving the sealing effect.

[0034] Working principle: In use, the insertion ring 805 on one side of the outer pipe 5 is inserted into the insertion slot 801, which causes the insertion ring 805 to squeeze the sealing ring 804. This causes the sealing ring 804 to move inward and squeeze the third spring 802, which in turn causes the third spring 802 to generate a rebound force. This allows the sealing ring 804 and the insertion ring 805 to fit tightly together, thus sealing the gap between the outer pipe 5 and the inlet / outlet water pipe 9 to prevent water leakage. Then, the drive motor 1 drives the fan wheel inside the pump body 10 to rotate and pump water. The water flow comes into contact with the buffer plate 606, causing the buffer plate 606 to move. The buffer plate 606 drives the connecting plate 605 to move, and the connecting plate 605 drives the sliding ring 604 to move. This causes the sliding ring 604 to squeeze the first spring 609 at the bottom, which absorbs the impact force of the water flow by contracting, preventing the water flow from directly impacting the fan wheel and thus avoiding damage to the fan wheel and affecting the pumping efficiency.
