Description

Technical Field

[0001] This utility model relates to the field of drainage diversion technology, specifically a water supply and drainage diversion device. Background Technology

[0002] A water supply and drainage diversion device is a piece of equipment used in water supply and drainage systems to distribute and control water flow. In scenarios where drainage needs to be diverted, it can effectively reduce drainage pressure and protect pipes from damage. The device typically includes a main pipe and a diversion box, both of which contribute to the rational distribution of water flow in the water supply and drainage system.

[0003] Chinese patent CN221798643U discloses a water supply and drainage diversion device, including a diversion box. The diversion box is connected to an inlet pipe and multiple outlet pipes. A filter screen is installed inside the diversion box, adjacent to the inlet pipe. A mounting plate is installed on the side of the filter screen adjacent to the inlet pipe, with brush bristles mounted on it. An upper sealing plate is fixed to the mounting plate, and a sealing strip A is provided around its outer periphery. A lower sealing plate is located directly below the mounting plate, with a sealing strip B around its outer periphery. A fixing rod connects the lower sealing plate to the mounting plate. A power assembly for driving the upper sealing plate to rise and fall is installed on the diversion box. A drain port is provided at the bottom of the diversion box, and a bottom shell is connected to the bottom of the diversion box. A hollow cavity is provided inside the bottom shell. This invention allows for convenient cleaning of the filter screen without disassembling it or closing valves, making it simple to operate and highly practical.

[0004] The aforementioned device facilitates the cleaning of the filter screen. However, when existing devices divert urban water supply and drainage, they typically treat sewage by overall purification or direct discharge, leading to increased purification costs and water waste. Furthermore, excessive accumulation of dirt and grime occurs after water sedimentation. Therefore, a water supply and drainage diversion device is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a water supply and drainage diversion device to solve the problems of increased purification costs and water waste, as well as excessive accumulation of dirt after water sedimentation, when existing devices divert urban water supply and drainage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water supply and drainage diversion device, comprising a water injection pipe and three manual sewage discharge pipes, each of the three manual sewage discharge pipes being fixedly installed with a water valve, and a diversion mechanism being provided between the water injection pipe and the three manual sewage discharge pipes; the diversion mechanism includes a first diversion box, a second diversion box, and a third diversion box, the lower part of the first diversion box being fixedly installed with an upper sewage discharge pipe, the lower part of the second diversion box being fixedly installed with a lower sewage discharge pipe, and a diversion pipe being fixedly installed between the first diversion box, the second diversion box, and the third diversion box, with two fastening seats fixedly installed on each diversion pipe, a rubber pad fixedly installed in the middle of the two fastening seats, a filter screen fixedly installed in the middle of the rubber pad, and four fastening bolt groups fixedly installed through the two fastening seats, and a water outlet pipe fixedly installed on one side of the third diversion box.

[0007] Preferably, the first diverter box is located above the second and third diverter boxes, and the second and third diverter boxes are on the same horizontal plane.

[0008] Preferably, the three manual drain pipes are fixedly installed on the lower side of the first diversion box, the second diversion box and the third diversion box respectively, and protrusions are fixedly installed on both sides of the two fastening seats.

[0009] Preferably, the first and second diversion boxes are provided with a sewage discharge mechanism, which includes two slatted rods and two valve seats. The two slatted rods are slidably installed on the upper side of the first and second diversion boxes, and a float is fixedly installed at one end of each of the two slatted rods. A support spring is fixedly installed between the float and the first and second diversion boxes and outside the two slatted rods. A limit groove is opened at the other end of each of the two slatted rods. The two valve seats are fixedly installed on the upper sewage pipe and the lower sewage pipe, respectively. A valve ball is rotatably installed inside each of the two valve seats, and a limit rod is fixedly installed on the valve ball and through the valve seat.

[0010] Preferably, the float is located at the upper part of the diversion pipe, and the limiting groove and the valve seat are on the same horizontal plane.

[0011] Preferably, the valve ball has a through-hole in the middle, and the limiting rod is embedded in the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This water supply and drainage diversion device controls the water flow into the first diversion box through the water inlet pipe. When the water level in the first diversion box exceeds the upper diversion pipe, it will flow to the second diversion box. When the water level in the second diversion box exceeds the lower diversion pipe, it will flow to the third diversion box. As the water flows through the diversion pipe, it will be purified by the filter screen. When the water level in the third diversion box exceeds the outlet pipe, the relatively pure water can be discharged from the outlet pipe. The device has the effect of distributing and purifying water quality.

[0014] 2) This device is used for water supply and drainage diversion. When the water level in the first and second diversion boxes exceeds the diversion pipe, the water flow will cause the float to float, thereby counteracting the supporting force of the support spring and causing the lever to move upward. When the lever moves upward, it can control the valve ball to rotate, allowing the dirt deposited inside the first and second diversion boxes to be discharged. When the water level in the first and second diversion boxes drops to the lower side of the diversion pipe, the valve ball will rotate in the opposite direction under the action of the support spring, restricting the water flow inside the upper and lower drain pipes, thus playing the role of sewage discharge and water level restriction. In use, the control water valve can actively remove the dirt deposited at the bottom of the first, second, and third diversion boxes. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-5 A water supply and drainage diversion device includes a water injection pipe 1 and three manually operated drain pipes 2. Each of the three manually operated drain pipes 2 is fixedly equipped with a water valve 3. A diversion mechanism 4 is provided between the water injection pipe 1 and the three manually operated drain pipes 2. The diversion mechanism 4 includes a first diversion box 401, a second diversion box 402, and a third diversion box 403. An upper drain pipe 404 is fixedly installed at the lower part of the first diversion box 401, and a lower drain pipe 405 is fixedly installed at the lower part of the second diversion box 402. A diversion pipe 406 is fixedly installed between the first diversion box 401, the second diversion box 402, and the third diversion box 403. Two fastening seats 407 are fixedly installed on the diversion pipe 406. A rubber pad 408 is fixedly installed in the middle of the two fastening seats 407. A filter screen 409 is fixedly installed in the middle of the rubber pad 408. Four fastening bolt groups 410 are fixedly installed through the two fastening seats 407. A water outlet pipe 411 is fixedly installed on one side of the third diversion box 403.

[0024] See Figure 2 and Figure 3 Furthermore, the first diversion box 401 is located above the second diversion box 402 and the third diversion box 403, and the second diversion box 402 and the third diversion box 403 are on the same horizontal plane. The three manual drain pipes 2 are respectively fixedly installed on the lower side of the first diversion box 401, the second diversion box 402 and the third diversion box 403, and protrusions are fixedly installed on both sides of the two fastening seats 407.

[0025] Specifically, the first diversion box 401 performs initial diversion of the convection. During use, sewage enters the first diversion box 401 through the water inlet pipe 1. When the water level in the first diversion box 401 reaches the upper diversion pipe 406, the water flows to the second diversion box 402 and undergoes initial filtration under the action of the upper filter screen 409. When the water level in the second diversion box 402 reaches the lower diversion pipe 406, the water flows to the third diversion box 403 and undergoes repeated filtration under the action of the lower filter screen 409. When the water level in the third diversion box 403 reaches the outlet pipe 411, relatively pure water can be discharged, achieving the function of sewage diversion and purification. At the same time, the location of the first diversion box 401 between the second diversion box 402 and the third diversion box 403 reduces the water pressure in the device, thereby avoiding damage to the device from water pressure.

[0026] Example 2

[0027] Combination Figure 1 , Figure 4 and Figure 5 A sewage discharge mechanism 5 is provided on the first diversion box 401 and the second diversion box 402. The sewage discharge mechanism 5 includes two folding rods 501 and two valve seats 505. The two folding rods 501 are slidably installed on the upper side of the first diversion box 401 and the second diversion box 402, and a float 502 is fixedly installed on one end of each of the two folding rods 501. A support spring 503 is fixedly installed between the float 502 and the first diversion box 401 and the second diversion box 402 and outside the two folding rods 501. A limit groove 504 is opened on the other end of each of the two folding rods 501. The two valve seats 505 are fixedly installed on the upper sewage pipe 404 and the lower sewage pipe 405, respectively. A valve ball 506 is rotatably installed inside each of the two valve seats 505. A limit rod 507 is fixedly installed on the valve ball 506 and through the valve seat 505.

[0028] See Figure 2 Furthermore, based on Embodiment 1, the float 502 is located at the upper part of the diversion pipe 406, the limiting groove 504 and the valve seat 505 are on the same horizontal plane, the valve ball 506 has a through hole in the middle, and the limiting rod 507 is embedded in the limiting groove 504.

[0029] Specifically, when the water level in the first diversion box 401 and the second diversion box 402 exceeds the diversion pipe 406, the float 502 will float up, thereby counteracting the supporting force of the support spring 503 and causing the bending rod 501 to move upward. When the bending rod 501 moves upward, it will drive the limiting rod 507 to rotate the valve ball 506, thereby discharging the dirt settled at the bottom of the first diversion box 401 and the second diversion box 402, achieving the descaling effect. When the water level inside the first diversion box 401 and the second diversion box 402 drops to the diversion pipe 406, the bending rod 501 will move downward under the action of the support spring 503, thereby driving the valve ball 506 to move in the opposite direction, thereby restricting the water flow in the upper drain pipe 404 and the lower drain pipe 405. In use, the dirt sediment can be actively discharged from the first diversion box 401 and located inside the second diversion box 402 and the third diversion box 403 by controlling the water valve 3.

[0030] In actual operation, the first diversion box 401 performs initial diversion of the convection. When in use, sewage enters the first diversion box 401 through the water inlet pipe 1. When the water level in the first diversion box 401 reaches the upper diversion pipe 406, the water will flow to the second diversion box 402 and undergo initial filtration under the action of the upper filter screen 409. When the water level in the second diversion box 402 reaches the lower diversion pipe 406, the water will flow to the third diversion box 403 and undergo repeated filtration under the action of the lower filter screen 409. When the water level in the third diversion box 403 reaches the outlet pipe 411, relatively pure water can be discharged, achieving the function of sewage diversion and purification. At the same time, the first diversion box 401 is located between the second diversion box 402 and the third diversion box 403, which reduces the water pressure in the device and thus avoids water pressure damage to the device.

[0031] When the water level in the first diversion box 401 and the second diversion box 402 exceeds the diversion pipe 406, the float 502 will float up, thereby counteracting the supporting force of the support spring 503 and causing the bending rod 501 to move upward. When the bending rod 501 moves upward, it will drive the limit rod 507 to rotate the valve ball 506, thereby discharging the dirt settled at the bottom of the first diversion box 401 and the second diversion box 402, achieving the descaling effect. When the water level inside the first diversion box 401 and the second diversion box 402 drops to the diversion pipe 406, the bending rod 501 will move downward under the action of the support spring 503, thereby driving the valve ball 506 to move in the opposite direction, thereby restricting the water flow in the upper drain pipe 404 and the lower drain pipe 405. In use, the dirt sediment can be actively discharged from the first diversion box 401 and located inside the second diversion box 402 and the third diversion box 403 by controlling the water valve 3.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
