Description

Technical Field

[0001] This utility model relates to the field of diversion device technology, and in particular to an energy-saving construction diversion device. Background Technology

[0002] During the construction of drainage pipe network renovation projects and other water-related renovation projects, it is usually required that the construction work area maintain a relatively dry working environment to meet the construction conditions and improve construction quality. However, the drainage pipe network is a branch system, and the renovated pipe section is the necessary route for drainage from the upstream area. This necessitates the use of diversion methods during construction to discharge upstream drainage to the downstream of the construction area. Depending on the construction conditions, commonly used drainage diversion methods include gravity flow diversion and pump drainage diversion.

[0003] Gravity flow diversion requires no additional power supply, saving energy and electricity. However, it requires the diversion pipe to be connected smoothly to the upstream pipe network and sloped towards the drainage endpoint. Since municipal drainage pipes are deeply buried, this requires excavation and pipe laying in the construction area, resulting in a long construction period. For deeply buried pipes, when the construction area is located on a busy urban road, it affects traffic flow, so it is rarely used in actual projects. Pump-assisted drainage diversion uses submersible sewage pumps for pressure drainage. Different sewage pumps are adapted according to different drainage volumes, and the system layout is flexible. However, in actual projects, it requires uninterrupted power supply, resulting in energy waste. Therefore, this solution proposes an energy-saving construction diversion device to solve the above problems. Utility Model Content

[0006] Upstream inspection well;

[0007] Construction inspection well, wherein the construction inspection well is located on one side of the upstream inspection well;

[0008] Downstream inspection well, wherein the downstream inspection well is located on one side of the construction inspection well;

[0009] A drainage pipe is installed at the bottom of an upstream inspection well, a construction inspection well, and a downstream inspection well, and the drainage pipe is used to connect the upstream inspection well, the construction inspection well, and the downstream inspection well.

[0010] A drainage assembly includes a siphon pipe that is inserted into the top of an upstream inspection well and inserted into the top of a downstream inspection well. A vacuum pump is installed on one side of the siphon pipe, a sealing component is installed inside the drainage pipe, and an electric valve is installed at one end of the siphon pipe.

[0011] Preferably, the other end of the siphon pipe is provided with a flared opening, and the inner wall of the bottom end of the upstream inspection well is provided with a support, with the flared opening located on the top of the support.

[0012] Preferably, the bottom of the siphon pipe is provided with multiple road surface supports, which are used to support the siphon pipe.

[0016] Preferably, the sealing element includes a sealing airbag inserted into the drain pipe, the sealing airbag being used to block water flow.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention utilizes a siphon tube, a vacuum pump, a sealing component, and an electric valve. In use, the upstream and downstream ends of the drainage pipe in the construction inspection well are first sealed with the sealing component. The electric valve is then closed. When the liquid level in the upstream inspection well rises to H4, the vacuum pump is started to evacuate the siphon tube. The liquid level inside the tube continuously increases with the increase in vacuum, eventually filling the downstream siphon tube after passing the highest point on the ground. When the siphon tube is full, the vacuum pump is turned off, and the electric valve is slowly opened to achieve siphon drainage, thus eliminating the need for digging and burying and uninterrupted power supply.

[0024] 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.

[0025] This utility model provides, for example Figure 1 - Figure 4 An energy-saving construction diversion device is shown, comprising:

[0026] Upstream inspection well 5;

[0027] Construction inspection well 12 is located on one side of the upstream inspection well 5;

[0028] Downstream inspection well 13 is located on one side of construction inspection well 12;

[0029] Drainage pipe 11 is installed at the bottom of upstream inspection well 5, construction inspection well 12 and downstream inspection well 13. Drainage pipe 11 is used to connect upstream inspection well 5, construction inspection well 12 and downstream inspection well 13.

[0030] The drainage assembly includes a siphon pipe 4 that is inserted into the top of the upstream inspection well 5 and the siphon pipe 4 that is inserted into the top of the downstream inspection well 13. A vacuum pump 8 is installed on one side of the siphon pipe 4, a sealing component is installed inside the drainage pipe 11, and an electric valve 9 is installed at one end of the siphon pipe 4.

[0031] The other end of the siphon pipe 4 is provided with a bell mouth 3. The inner wall of the bottom of the upstream inspection well 5 is provided with a support 2, and the bell mouth 3 is located on the top of the support 2. The inner wall of the bottom of the downstream inspection well 13 is provided with a liquid level control box 10. The siphon pipe 4 is inserted and connected inside the liquid level control box 10. The inlet of the vacuum pump 8 is provided with an electric contact pressure gauge 15, which is used to detect pressure.

[0032] It should be noted that the electric valve 9 is an existing solenoid valve. The occurrence of the siphon phenomenon depends on the vacuum degree of the pipeline. It is necessary to ensure that the entire system is maintained in a negative pressure state. The siphon tube 4 is made of negative pressure resistant PVC material, and the interface is connected by adhesive or heat fusion. Due to the presence of large particles in the fluid, support 2 is manufactured together with a grid. The grid bars are spaced 30mm apart. Support 2 and bell mouth 3 are made of stainless steel. A filter screen is installed at the bottom of bell mouth 3 to further filter objects in the water. The elevation relationships are as follows: H1 is the bottom elevation of the bell mouth, which is 0.5m higher than the bottom of inspection well 5; H2 is the elevation of level control box 10, which is 0.2m higher than H1 to ensure the siphon water seal effect; H3 is the elevation of electric valve 9, which is 0.2m higher than H2; and H4 is the siphon start level, which is 1.5m higher than H2. When the diameter of siphon pipe 4 is less than or equal to DN400, level control box 10 can be made of a lightweight plastic bucket with a diameter of 600mm, and its height can be selected according to the construction conditions. When the diameter of siphon pipe 4 is greater than DN400, an overflow weir can be built in the downstream inspection well 13 to form the siphon water seal effect.

[0033] Specifically, the bottom of the siphon pipe 4 is provided with multiple road support blocks 6, which are used to support the siphon pipe 4. The control ends of the vacuum pump 8, electric valve 9 and electric contact pressure gauge 15 are all provided with control lines 14. One end of the control line 14 is electrically connected to the control box 7. The sealing component includes a sealing airbag 1 that is inserted and connected inside the drain pipe 11. The sealing airbag 1 is used to block the water flow.

[0034] It should be noted that the height of the multiple road support blocks 6 decreases sequentially from the high point to the low point of the siphon pipe 4. The road support blocks 6 support the middle part of the siphon pipe 4 to prevent the siphon pipe 4 from bending in the middle due to water pressure. Two sealing airbags 1 are set up. When in use, they are used to block the drainage pipe 11 upstream and downstream of the upstream inspection well 5, thereby cutting off the water flow.

[0035] Furthermore, before starting the device, the electric valve 9 is closed. When the liquid level in the upstream inspection well 5 rises to H4, the vacuum pump 8 is started to evacuate the siphon pipe 4. The liquid level in the pipe continuously increases with the increase in vacuum, filling the downstream siphon pipe 4 after passing the highest point on the ground. When the water flow fills the siphon pipe 4, the vacuum pump 8 is closed, and the electric valve 9 is slowly opened to achieve siphon drainage. As the liquid level in the upstream inspection well 5 continuously rises, the siphon drainage volume continuously increases until it maintains a constant liquid level. As the liquid level in the upstream inspection well 5 continuously decreases, the siphon drainage volume continuously decreases. When the liquid level in the upstream inspection well 5 drops to H2, the siphon phenomenon basically stops. However, due to the water seal effect of the end liquid level control box 10, the negative pressure water filling state of the siphon pipe 4 is not destroyed. When the liquid level in the upstream inspection well 5 continuously rises, the siphon phenomenon restarts. An electric contact pressure gauge 15 is installed at the highest point of the siphon pipe 4. When the vacuum level at the electric contact pressure gauge 15 drops below the threshold, the vacuum pump 8 is started in conjunction to maintain the continuous occurrence of siphon.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
