Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater and sewage diversion wells, in particular to a rainwater and sewage diversion well with a diversion structure. Background Art
[0002] Separate drainage wells are used to separate rainwater and sewage. Rainwater is drained directly into the river through the stormwater network, while sewage is collected through the sewage network and sent to a sewage treatment plant for treatment, preventing it from entering the river and causing pollution.
[0003] In order to avoid sewage remaining in the well, the sewage outlet is usually set at the bottom of the well, such as Figure 5 As shown, the sewage outlet at the bottom of the well is also connected to a 90° elbow, so that the outlet direction of the sewage outlet is set horizontally, which is convenient for connecting to the sewage pipe.
[0004] Since the elbow and the rainwater and sewage diversion well are both made of plastic, they are not only easy to deform, but also because the sewage outlet is perpendicular to the sewage pipe, if there is an error in the position, the elbow is easily pulled by the axial direction of the sewage pipe, so the connection between the sewage outlet and the elbow is prone to leakage. Utility Model Content
[0005] In order to solve the technical problems in the background technology, the utility model discloses a rainwater and sewage diversion well with a diversion structure.
[0006] The utility model provides a rainwater and sewage diversion well with a diversion structure, comprising a well body, a sewage outlet provided at the lower end of the well body, and an inclined sewage discharge channel provided at the lower end of the well body;
[0007] The sewage channel and the well body are formed in one piece;
[0008] The outlet of the sewage channel is set as a sewage outlet;
[0009] The well body is provided with interpenetrating holes;
[0010] The sewage pipe passes through the through hole and is connected to the lower end of the sewage channel;
[0011] The sewage pipe is sealed and connected to the well body through a sealing ring.
[0012] The sewage channel is integrally formed with the well body, which has higher strength and more stable structure; the sewage pipe is directly connected to the sewage channel in a horizontal state, eliminating the elbow, and its connection strength is higher and more stable; thus, sewage is not easy to leak.
[0013] If the inclination angle of the sewage channel is too small, when the sewage discharge volume is small, precipitation is likely to form in the sewage channel; if the inclination angle of the sewage channel is too large, it will occupy more space in the well body, resulting in a smaller well body capacity. Based on this, further improvements are: the inclination angle of the sewage channel is 5±1.5°.
[0014] Furthermore, the lowest end of the sewage channel is higher than the lowest end of the inner wall of the sewage pipe or is flush with the lowest end of the inner cavity of the sewage pipe, so as to ensure that no sewage will remain in the well body.
[0015] In order to improve the connection strength and stability between the sewage pipe and the well body, specifically: the inlet end of the sewage pipe is inserted into the inside of the well body.
[0016] When the sewage pipe is deformed or its position moves, it is easy to cause leakage. Based on this, a further improvement is that a clamping platform is provided on the inner wall of the sewage outlet; and the inlet end of the sewage pipe is clamped to the clamping platform.
[0017] In order to improve the sealing performance between the sewage pipe and the well body, a further design is that raised serrations are provided on the inner side of the sealing ring.
[0018] The sewage pipe easily moves away from the well body under axial tension. Based on this, a further improvement is to direct the serrations away from the well body toward the interior of the well body. This arrangement allows the sewage pipe to deform and contract in the direction of the tension when it is pulled away from the well body, increasing the pressure between the serrations and the sewage pipe, thereby increasing the resistance of the sewage pipe and making it less likely to move axially when subjected to tension.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0027] like Figure 1-Figure 3 As shown, the present invention discloses a rainwater and sewage diversion well with a diversion structure, comprising a well body 1, the lower end of which is provided with an inclined drainage channel 3 and a through hole 4 directly opposite the lower end of the drainage channel 3. The drainage channel 3 has an inclination angle of 5±1.5° to prevent the drainage channel from being too inclinated, which would easily form sediment in the drainage channel 3 when the sewage discharge volume is small; and to avoid the drainage channel 3 from being too inclinated, which would occupy more space in the well body 1 and reduce the well body 1 capacity.
[0028] The drainage channel 3 is formed integrally with the well body 1, which has higher strength and more stable structure. The outlet of the drainage channel 3 is set as the sewage outlet 2.
[0029] The sewage pipe 5 is arranged horizontally, passes through the insertion hole 4, and is connected to the lower end of the sewage channel 3. The insertion hole 4 is also clamped with a sealing ring 6, and the outer wall of the sealing ring 6 is provided with an annular U-shaped groove, which is clamped on the hole wall of the insertion hole 4 to achieve installation and fixation.
[0030] The sewage pipe 5 is plugged into the inner hole of the sealing ring 6 to achieve a sealed connection between the sewage pipe 5 and the well body 1. Figure 4 As shown, the inner side of the sealing ring 6 is provided with raised serrations 8, which point toward the interior of the well body 1. With this arrangement, when the sewage pipe 5 is subjected to a pulling force away from the well body 1, the serrations 8 will deform in the direction of the pulling force and contract, increasing the pressure between the sewage pipe 5 and the serrations 8, thereby increasing the resistance of the sewage pipe 5 and making it difficult for the sewage pipe 5 to move axially when subjected to the pulling force.
[0031] The inlet end of the sewage pipe 5 engages the clamping plate 7, which then passes through the insertion hole 4 and engages with the clamping plate 7. This ensures the installation and positioning of the sewage pipe 5, maintaining the structural and positional stability of the inlet of the sewage pipe 5. Furthermore, the sewage pipe 5 is inserted into the well body 1 for a certain distance, further improving the positional stability of the sewage pipe 5.
[0032] After the sewage pipe 5 is connected, the lowest end of the sewage channel 3 is higher than the lowest end of the inner wall of the sewage pipe 5 or is flush with the lowest end of the inner cavity of the sewage pipe 5. This ensures that no sewage will remain in the well body 1.
[0033] The utility model eliminates the need for elbows, and its connection strength is higher and more stable; thus, sewage is not easily leaked.
[0034] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
