DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides an anti-blocking device for building mechanical and electrical water supply and drainage, including a delivery pipe 102, a filtering assembly and a cutting and separating assembly. One end of the delivery pipe 102 is detachably mounted on one end of the water inlet pipe 101, and the other end of the delivery pipe 102 is connected to the water inlet end of the water pump for water supply and drainage. The filtering assembly is arranged at an end of the water inlet pipe 101 away from the delivery pipe 102, and is used for filtering and preventing blockage during the water supply and drainage process. The filtering assembly includes an operating pipe 201 fixed to the side of the water inlet pipe 101 away from the delivery pipe 102. A plurality of groups of filtering holes 202 are provided on the surface of the operating pipe 201 along the radial direction. The plurality of groups of filter holes are arranged along the axial direction of the operating pipe. A cutting and separating assembly for cutting and separating blocked debris on each group of filter holes 202 is provided on the outer periphery of the operating pipe 201.

[0021] Specifically, in the process of using the water supply and drainage device to discharge wastewater from the corresponding positions of the building and mechanical and electrical buildings, the transported wastewater is filtered through the multiple groups of filter holes 202 on the operating pipe 201 to achieve the effect of anti-blocking. In the anti-blocking process, when the debris in the transported part of the waste liquid causes blockage to the filter hole 202, the debris on the filter hole 202 is cut through the cutting separation component to avoid blockage.

[0022] On the basis of the above embodiment, in a preferred embodiment, the cutting and separation component includes a first annular plate 301, a second annular plate 302 and a cutter 303. The first annular plate 301 is sleeved on the first side of the operating tube 201, and the second annular plate 302 is sleeved on the second side of the operating tube 201. A cutter 303 for cutting debris blocking the filter hole 202 is fixed between the first annular plate 301 and the second annular plate 302. A transmission component for driving the cutter 303 to rotate is provided on the second side of the operating tube 201, and a guide component for connecting and guiding the first annular plate 301 is provided on the outer circumference of the first annular plate 301.

[0023] During the drainage and anti-clogging process, the first annular plate 301 and the second annular plate 302 are driven to rotate through the transmission component. During the movement of the first annular plate 301 and the second annular plate 302, each group of cutters 303 is driven to move. During the movement of the cutters 303, the cutters 303 are used to cut off and separate the debris blocking the filter holes 202, thereby ensuring the permeability of the filter holes 202 and further facilitating continuous and stable anti-clogging operations.

[0024] Specifically, multiple groups of cutters 303 are provided, and these groups are fixed in an annular array between the first annular plate 301 and the second annular plate 302. A gap cutter 303 is provided between the cutters 303 and the operating tube 201, and is initially positioned between two adjacent groups of filter holes 202. The multiple groups of cutters 303 arranged in an annular array facilitate more efficient cutting and separation of debris.

[0025] like Figure 2-3 As shown, the transmission assembly includes a piston rod 401 which is slidably connected to the side of the operating tube 201 away from the water inlet pipe 101, a circular plate 402 is fixed to the end of the piston rod 401, a connecting assembly is provided between the circular plate 402 and the delivery tube 102, and the connecting assembly is used to connect and guide the circular plate 402, a transmission pin 403 is fixed to the side of the circular plate 402 close to the operating tube 201, and a transmission plate 404 is fixed to the side of the second annular plate 302 close to the piston rod 401, and the transmission plate 404 is provided with an inclined surface 405 for abutting the end of the transmission pin 403 for transmission.

[0026] It should be noted here that: during the drainage and anti-clogging process, when debris in part of the transported waste liquid causes blockage to the filter hole 202, with the continuous driving action of the water pump and the blocking effect of the filter hole 202, the pressure inside the operating tube 201 increases. Under the action of pressure, the piston rod 401 moves toward the inside of the operating tube 201, and in the process of movement, the circular plate 402 is driven to move. In the process of movement of the circular plate 402, one end of the transmission pin 403 is offset against the inclined surface 405 on the transmission plate 404, and the first annular plate 301 and the second annular plate 302 are driven to rotate through the offset transmission action.

[0027] On the basis of the above embodiment, in a preferred embodiment, the connecting assembly includes multiple groups of sleeves 501 fixedly arranged on the circular plate 402, one end of the sliding rod 502 is slidingly connected to the sleeve 501, and the other end of the sliding rod 502 is fixedly connected to the circular plate 402. A first spring 503 is provided on the outer side of the sleeve 501 and the sliding rod 502, one end of the first spring 503 is fixedly connected to the end face of the operating tube 201, and the other end is fixedly connected to the circular plate 402.

[0028] It should be noted that the movement of the circular plate 402 is guided by the sleeve 501 and the slide rod 502 , and the circular plate 402 is reset after movement by the first spring 503 .

[0029] like Figure 4 As shown, a sliding ring 602 is provided on the outer periphery of the first annular plate 301. Several sets of guide assemblies are provided on the sliding ring 602, and the multiple sets of guide assemblies are arranged in a circular array. The guide assemblies include two sets of mounting brackets 601, which are fixedly mounted on the sliding ring 602. The positions of the mounting brackets 601 correspond to the positions of the cutters 303. A connecting plate 603 is fixed to the first annular plate 301. The connecting plate 603 is located between the two sets of mounting brackets 601 and is slidably connected to the sliding ring 602. A second spring 604 is sleeved on the sliding ring 602. The two ends of the second spring 604 are respectively connected to one of the mounting brackets 601 and the connecting plate 603.

[0030] It should be noted here that: during the movement of the first annular plate 301 and the second annular plate 302, the connecting plate 603 is driven to move. During the movement of the connecting plate 603, the sliding action of the connecting plate 603 on the sliding ring 602 guides the movement of the connecting plate 603 and the first annular plate 301 and the second annular plate 302. The second spring 604 facilitates the reset push of the first annular plate 301 and the second annular plate 302 after movement.

[0031] Working principle: When using the water supply and drainage device to discharge wastewater from the corresponding positions of the building and mechanical and electrical buildings, the two ends of the delivery pipe 102 are installed and connected to the water inlet end of the water pump and the water inlet pipe 101 respectively. After the installation is completed, through the driving action of the water pump and the connection action of the delivery pipe 102, the wastewater at the corresponding position passes through the water inlet pipe 101 and the delivery pipe 102 and is transported outward to complete the drainage operation. During the water intake process, the front end of the water inlet pipe 101 filters the transported wastewater through the multiple groups of filter holes 202 on the operating pipe 201 to achieve an anti-clogging effect.

[0032] In the process of drainage and anti-clogging, when the debris in the transported waste liquid causes clogging to the filter hole 202, with the continuous driving action of the water pump and the clogging effect of the filter hole 202, the negative pressure inside the operating tube 201 increases. Under the action of the pressure, the piston rod 401 moves toward the inside of the operating tube 201, and in the process of movement, the circular plate 402 is driven to move. In the process of movement of the circular plate 402, one end of the transmission pin 403 is abutted against the inclined surface 405 on the transmission plate 404, and the first annular plate 301 and the second annular plate 304 are driven by the offset transmission effect. 2 rotates, and during the movement of the first annular plate 301 and the second annular plate 502, each group of cutters 303 is driven to move. During the movement of the cutters 303, the cutters 303 cut off the debris blocking the filter holes 202. After the blockage is cut off, the filter holes 202 are unblocked. At this time, the negative pressure inside the operating tube 201 is reduced. Under the action of pressure and the elastic action of the first spring 503, the piston rod 401 is driven to reset, thereby driving the cutters to reset, ensuring the permeability of the filter holes 202, and further facilitating continuous and stable anti-blocking operation.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
