[0030] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] See also Figures 1 to 11 The present invention preferably provides a technical solution: a modular structure of a submersible water tank drain outlet, including: a first port, a diverter shock-absorbing pipe module and a second port, the first port is connected to the submersible water tank, and the second port is used for draining the submersible water tank; a quick-release connection module 1 is respectively installed between the diverter shock-absorbing pipe module and the first port and the second port; each group of quick-release connection modules 1 includes a tank body 101, and connecting pipes 102 that are connected to the tank body 101 and distributed in a cross shape, and the port of each connecting pipe 102 is provided with a first quick-release component 5; it also includes a shock-absorbing and buffering component arranged inside the tank body 101, and the shock-absorbing and buffering component is used for further buffering and shock absorption during pipeline operation.

[0033] This application, combined Figure 1 、 2 As shown in FIG3 and FIG4, the first port, the second port and the diversion shock-absorbing tube module are connected by a quick-release connection module 1 to realize the modular assembly and disassembly process of the device. Figure 5 、 6 As shown, the quick-release connection module 1 includes a tank body 101 and connecting pipes 102 connected to the tank body 101 and arranged in a cross shape. The first quick-release assembly 5 provided at the port of each connecting pipe 102 can be connected to the first port and the second port to realize the modular assembly and disassembly process of the device. In conjunction with the shock-absorbing and buffering assembly provided in the tank body 101, the shock-absorbing and buffering process of the water is further realized. In addition, due to the structural design of the diverter shock-absorbing pipe module, the diverter pressure reduction process of the water is realized in a diverter manner, thereby protecting the connection points of each pipe and improving the service life of the device.

[0034] The present invention realizes the modular quick assembly and disassembly process of the first port, the second port and the diverter shock-absorbing tube module through the structural design of the quick-release connection module 1, and combines the structural setting of the diverter shock-absorbing tube module and the shock-absorbing buffer assembly to further buffer the impact of water pressure on the connection points of each pipeline, thereby improving the service life of the device.

[0035] Furthermore, the first quick-release assembly 5 consists of a hook and a driving part. When the driving part drives the hook to operate, the hook can act on the end of the first port and seal the first port with the connecting pipe 102; the hook includes a mounting sleeve 501, and a mounting seat 502 annularly arranged on the outer periphery of the mounting sleeve 501, and a transmission member 503 installed on each mounting seat 502, one end of which is provided with an arc hook, and the other end of which is connected to the driving part; it also includes a first spring 504 arranged between the mounting sleeve 501 and the transmission member 503.

[0036] Here, the first quick-release assembly 5 connected to the first port and the shunt shock absorber tube module is taken as an example. The specific first quick-release assembly 5 is composed of a hook and a driving part, and the driving part serves as the driving structure of the hook. The transmission member 503 where the hook is located is rotatably connected to the mounting seat 502 on the mounting sleeve 501, and the arc hook set at one end can be connected to the end of the first port, and the other end is connected to the driving part. Cooperating with the action of the first spring 504, when the driving part is running, the transmission member 503 can be pitched and deflected around the mounting seat 502, so that several arc hooks are hooked inward to realize the sealed docking process between the mounting sleeve 501 and the end of the first port, and when several arc hooks expand outward, the two are separated. This design can realize the quick installation and removal process of the two by simply operating the driving part.

[0037] Furthermore, the driving part consists of a transmission assembly, a driving handle 506 and a snap assembly between the two; the transmission assembly includes a transmission sleeve 507, which is rotatably connected to the connecting pipe 102 and placed inside the mounting sleeve 501, and a transmission wedge 508 distributed in an annular manner on the outer wall of the transmission sleeve 507; it also includes a limiting hole 509 annularly opened on the side wall of the mounting sleeve 501, and a limiting column 505 arranged in the limiting hole 509, one end of which is inwardly in conflict with the corresponding transmission wedge 508, and the other end of which is outwardly connected to the end of the corresponding transmission member 503 away from the arc hook; the driving handle 506 is rotatably connected to the side of the transmission sleeve 507 away from the first port and is used to drive the transmission assembly to operate.

[0038] like Figure 7 、 8 As shown in Figures 9, 10, and 11, since the outer wall of the transmission sleeve 507 is provided with a plurality of transmission wedges 508, and the slopes of the plurality of transmission wedges 508 here decrease or increase in one direction in sequence, and cooperate with the limiting column 505 provided in the limiting hole 509, one end of the limiting column 505 is inwardly in conflict with the corresponding transmission wedge 508, and the other end thereof is outwardly connected to the end of the corresponding transmission member 503. Therefore, when the driving handle 506 is rotated to rotate the plurality of transmission wedges 508, if the high slope of the transmission wedge 508 gradually conflicts with the limiting column 505, the plurality of limiting columns 505 can be driven to expand outward. At this time, the arc hooks where the plurality of transmission members 503 are located can be driven to grab inward, so that the mounting sleeve 501 is sealed and docked with the end of the first port, and the plurality of first springs 504 here are in a compressed state;

[0039] When the driving handle 506 is operated in the reverse direction, the transmission members 503 lose the transmission function of the limit column 505. At this time, the arc hooks where the transmission members 503 are located can expand outward and disengage from the first port through the action of the first spring 504.

[0040] Furthermore, the buckle assembly includes a card slot 16 and a slide slot 11, which are respectively opened on the side walls of the driving handle 506 and the mounting sleeve 501 and are distributed in a ring shape; and a slider 12 slidably installed inside each slide slot 11, and the slider 12 has a connecting strip 14 fixed on its outer wall, and a second spring 13 is connected between it and the inner wall of the slide slot 11; it also includes a card block 15 arranged at the end of the connecting strip 14 away from the second spring 13, and the card block 15 is adapted to engage with the corresponding card slot 16. When the card block 15 is engaged with the card slot 16, it is used to limit and lock the driving handle 506, and when the card block 15 is disengaged from the card slot 16, it is used to unlock the driving handle 506.

[0041] like Figure 5 、 6As shown, the connecting bar 14 is slidably mounted on the slide 11 through the slider 12, and a second spring 13 is connected between the slide 11 and the slider 12 for resetting the block 15. At the same time, the block 15 provided at the end of the connecting bar 14 is adapted to engage with the slot 16. Therefore, when the driving handle 506 needs to be rotated, as shown in FIG. Figure 5 、 6 As shown, at this time, by pushing the connecting strip 14 toward the first port, the block 15 can be disengaged from the card slot 16, thereby realizing the unlocking process of the driving handle 506. After completing the driving action of the driving handle 506, release the hand, and the block 15 will be docked with the card slot 16, thereby realizing the locking process of the driving handle 506. This design can maintain the docking of the first port and the mounting sleeve 501.

[0042] Furthermore, the first port includes an inlet pipe 3, and a second quick-release assembly arranged at the water inlet end of the inlet pipe 3. The second quick-release assembly has the same structure as the first quick-release assembly 5 and is sealed and docked with the water tank of the submersible; it also includes a connecting plate 301 arranged at the water outlet end of the inlet pipe 3, and the hook portion of the first quick-release assembly 5 acts on the side of the connecting plate 301 away from the mounting sleeve 501, and docks the connecting plate 301 with the mounting sleeve 501; it also includes a sealing ring arranged at the connection between the connecting plate 301 and the mounting sleeve 501.

[0043] Here, the water inlet end and the water outlet end of the water inlet pipe 3 are respectively provided with a second quick-release component and a connecting plate 301, and the second quick-release component can be sealed and docked with the water tank of the submersible, and the connecting plate 301 is docked with the hook portion where the first quick-release component 5 is located. Figure 2 、 6 As shown, the hook portion acts on the side of the connection plate 301 away from the installation sleeve 501 and makes the connection plate 301 and the installation sleeve 501 sealed and docked;

[0044] The sealing ring provided at the connection between the connecting plate 301 and the mounting sleeve 501 further improves the sealing performance of the connection between the two.

[0045] Furthermore, a plurality of rubber pads 302 are provided on a side of the connecting plate 301 away from the mounting sleeve 501 , and the plurality of rubber pads 302 correspond to the plurality of transmission members 503 in a one-to-one manner.

[0046] Combine Figure 7 As shown, when the plurality of transmission members 503 realize pitch deflection under the action of the driving part, the arc hooks arranged at their ends can act on the rubber pads 302 on the side walls of the connecting disk 301. The rubber pads 302 arranged here can improve the tightness of the arc hooks' grip on the connecting disk 301.

[0047] Furthermore, the second port includes a drain pipe 4, the water inlet end of the drain pipe 4 is sealed and connected to the diversion shock absorber pipe module through a quick-release connection module 1, and the other end is used for drainage. Figure 1 、2 , as shown in 4.

[0048] Example 2

[0049] As another embodiment of the present invention, the diverter shock-absorbing tube module includes a first diverter tube 2 and two second diverter tubes 6 on both sides of the first diverter tube 2. The first diverter tube 2 is sealed and docked with two connecting tubes 102 arranged opposite to each other in two sets of quick-release connection modules through a first quick-release assembly 5; the two second diverter tubes 6 are respectively sealed and docked with the two connecting tubes 102 at the top and bottom of the two sets of quick-release connection modules 1 through the first quick-release assembly 5.

[0050] Known, such as Figure 4 As shown, each tank body 101 has connecting pipes 102 arranged thereon that are distributed in a cross pattern, and the two tank bodies 101 have two connecting pipes 102 arranged opposite to each other, respectively docked with the two ends of the first diversion pipe 2 where the diversion shock-absorbing pipe module is located, and the two connecting pipes 102 arranged opposite to each other are respectively docked with the first port and the second port, while the upper and lower connecting pipes 102 are respectively docked with the two second diversion pipes 6, thereby realizing modular assembly of each structure, and due to the setting of the first diversion pipe 2 and the second diversion pipe 6, the water flowing out of the first port is diverted, thereby realizing the buffering and shock-absorbing process at the pipeline connection.

[0051] Furthermore, both groups of shock-absorbing and buffering components are composed of buffer nets 17, and the two buffer nets 17 are symmetrically distributed, wherein the buffer net 17 close to the water inlet pipe 3 is used to filter the water flow flowing into the diversion shock-absorbing pipe module through the water inlet pipe 3, and the buffer net 17 close to the drain pipe 4 is used to filter the water flow flowing into the drain pipe 4 through the diversion shock-absorbing pipe module; and the telescopic components 18 are respectively arranged on the opposite sides of the two buffer nets 17, and the end of the telescopic component 18 away from the buffer net 17 is connected to the corresponding tank body 101 for resetting the buffer net 17.

[0052] In this embodiment, the two groups of shock absorbing and buffering components are composed of buffer nets 17, and the two buffer nets 17 are respectively arranged inside the two tanks 101 and are symmetrically distributed. In combination with the telescopic components 18 respectively arranged on the back sides of the two buffer nets 17, Figure 4 As shown, when water flows from the first port to Figure 4 In the right tank body 101 shown, the right buffer net 17 not only performs a buffering process but also has a filtering function. When the initially filtered water flows through the diversion pipe and enters the left tank body 101, the buffer net 17 in the left tank body 101 can perform a secondary filtering and buffering. This design not only achieves buffering and shock absorption but also further realizes the filtering process of the water flow. The telescopic component 18 not only improves the installation stability of the buffer net 17 but also provides power for the resetting of the buffer net 17.

[0053] The buffer net 17 is a conventional mature technology, and is composed of a telescopic sleeve, a telescopic rod and a spring therebetween.

[0056] In this embodiment, combined with Figure 2 As shown, the water inlet valve 7, the first drain valve 9, and the second drain valve 8 are set. When the buffer net 17 needs to be backwashed, the second drain valve 8 is closed and the water inlet valve 7 is opened, so that the backwash water flows from left to right through the two tank bodies 101 in sequence, and the impurities on the two buffer nets 17 can be flushed off the buffer nets 17. The sewage after flushing can be discharged through the second drain valve 8 and the first drain valve 9 respectively. In this design, the backwash process of the two buffer nets 17 is realized by installing the water inlet valve 7 on the drain pipe 4, thereby reducing the blockage of the two buffer nets 17.
