Description

Technical Field

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

[0002] In water supply and drainage systems, diversion devices are key components for achieving water flow distribution.

[0003] Traditional diversion devices have the following problems:

[0004] 1. When using it, a filter screen is usually added inside the main pipe to filter impurities in the water. However, impurities in the main pipe are easy to accumulate on the surface of the filter screen, which can cause poor water flow or even blockage. Frequent manual cleaning is required, resulting in high maintenance costs.

[0005] 2. There is a lack of effective blocking devices for the water flow in the diversion pipe, making it difficult to adjust the water flow size of each diversion.

[0006] To solve the above problems, this utility model proposes a diversion device for water supply and drainage engineering. Utility Model Content

[0007] The technical problem this invention aims to solve is that traditional diversion devices are prone to clogging and it is difficult to control the size of the diverted water flow.

[0008] To achieve the above functions, the technical solution adopted by this utility model is as follows: a diversion device for water supply and drainage engineering, including a T-shaped main pipe and a diversion pipe fixedly connected to the lower end of the T-shaped main pipe and arranged opposite to it, the diversion pipe is provided with a blocking component, and a self-cleaning filter component is fixedly provided on the inner wall of the upper half of the T-shaped main pipe.

[0009] The blocking component includes a handle that is rotatably mounted on the outer wall of the diversion tube, and one end of the handle extends into the inner wall of the diversion tube and is connected to a spherical flow blocking block. The spherical flow blocking block has symmetrically opened circular holes on its upper and lower sides.

[0010] The self-cleaning filter assembly includes an annular strip fixedly connected to the inner wall of the T-shaped main pipe, and a filter screen is fixedly installed on the inner side of the annular strip. A cleaning mechanism is provided at the upper edge of the annular strip.

[0011] Furthermore, two limiting blocks for limiting the handle are fixedly installed on the outer wall of the diversion pipe.

[0012] Furthermore, the spherical flow-blocking block has a hollow center, and its diameter is the same as the inner diameter of the diversion pipe.

[0013] Furthermore, the cleaning mechanism includes an annular pressure sensor fixedly disposed on the upper end of the edge of the annular strip, and a plurality of vibrators cooperating with the annular pressure sensor are fixedly arranged in an annular array at the lower end of the annular strip.

[0014] Furthermore, the annular strip is internally embedded with multiple signal converters located between the annular pressure sensor and the vibrator. Each signal converter has wires connected to both ends, and the wires at the upper and lower ends are connected to the annular pressure sensor and the vibrator, respectively.

[0015] Furthermore, the gaps between the annular pressure sensor, signal converter, wire, and vibrator are all filled with sealing material.

[0016] The beneficial effects of this utility model by adopting the above structure are as follows:

[0017] 1. Equipped with a self-cleaning filter component, which senses the water pressure through a pressure sensor and links with the vibrator to achieve automatic cleaning when the filter screen is clogged, reducing the frequency of manual maintenance;

[0018] 2. Equipped with a blocking component, the on / off state of the diversion pipe can be quickly switched by the cooperation of the spherical flow blocking block and the handle, making it convenient to control the water flow in each diversion. Attached Figure Description

[0025] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] refer to Figure 1-4 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: a diversion device for water supply and drainage engineering, including a T-shaped main pipe 1 and a diversion pipe 2 fixedly connected to the lower end of the T-shaped main pipe 1 and arranged opposite to it. The diversion pipe 2 is provided with a blocking component, and a self-cleaning filter component is fixedly provided on the inner wall of the upper half of the T-shaped main pipe 1.

[0029] The self-cleaning filter assembly includes an annular strip 5 fixedly connected to the inner wall of the T-shaped main pipe 1, and a filter screen 8 is fixedly installed on the inner side of the annular strip 5. A cleaning mechanism is provided at the upper edge of the annular strip 5.

[0030] like Figure 2-5 As shown, the cleaning mechanism includes an annular pressure sensor 9 fixedly installed at the upper edge of the annular bar 5. Multiple vibrators 12, cooperating with the annular pressure sensor 9, are fixedly arranged in an annular array at the lower end of the annular bar 5. Multiple signal converters 10 are embedded inside the annular bar 5, located between the annular pressure sensor 9 and the vibrators 12. Wires 11 are connected to both ends of the signal converters 10, and the upper and lower wires 11 are connected to the annular pressure sensor 9 and the vibrators 12, respectively. Water flows through the filter screen 8, and impurities are retained on the surface of the filter screen 8. At this time, the annular pressure sensor 9 detects a normal pressure value, and the vibrators 12 do not start. When the filter screen 8 becomes clogged, causing the water pressure to rise above a threshold, the annular pressure sensor 9 triggers the vibrators 12 through the signal converters 10, vibrating to remove impurities from the filter screen 8 and restore smooth water flow, thus achieving self-cleaning and anti-clogging. The gaps between the annular pressure sensor 9, the signal converters 10, the wires 11, and the vibrators 12 are all filled with sealing material to prevent liquid seepage and damage to internal parts.

[0031] Example 2:

[0032] Based on Example 1, in order to achieve flexible adjustment of the water flow within each branch, such as Figure 1-5As shown, the blocking assembly includes a handle 4 that is rotatably mounted on the outer wall of the diversion pipe 2, and one end of the handle 4 extends into the inner wall of the diversion pipe 2 and is connected to a spherical flow-blocking block 6. The spherical flow-blocking block 6 has symmetrically arranged circular holes 7 on its upper and lower sides. Two limiting blocks 3 for limiting the handle 4 are fixedly mounted on the outer wall of the diversion pipe 2. The center of the spherical flow-blocking block 6 is hollowed out and its diameter is the same as the inner diameter of the diversion pipe 2. When in use, the handle 4 is rotated so that the circular hole 7 of the spherical flow-blocking block 6 is aligned with the direction of water flow. The water flows through the T-shaped main flow pipe 1 and is diverted to the diversion pipe 2. At this time, it is in a conductive state.

[0033] Rotating handle 4 ninety degrees causes the non-porous surface of the spherical flow block 6 to block the water flow, thus closing the diversion pipe 2. The limiting block 3 restricts the rotation range of handle 4 to ensure reliable blocking. At this time, it is in the blocking state.
