Abstract
Description
Technical Field
[0001] This application relates to drainage technology for dewatering wells, and more particularly to a frost-proof drainage structure for dewatering wells. Background Technology
[0002] In some coal mining areas in the north, winter temperatures are low, and in order to ensure the normal operation of the drainage system in the mining area, it is usually necessary to protect the drainage pipes from freezing.
[0003] Currently, drainage pipes in dredging wells are generally protected from freezing by being buried underground and covered with soil, with a burial depth of ≥3m. However, this method requires excavating trenches on the ground to place the drainage pipes, and the burial depth of the pipes must exceed the depth of the frozen soil, typically ≥3m, meaning the trench depth must also be ≥3m. This results in a large amount of construction work being done when burying drainage pipes, and the depth of the trenches is also inconvenient for installing the drainage pipes. Utility Model Content
[0004] This application provides a frost-proof drainage structure for dredging wells to solve the problem that existing frost-proofing methods for buried drainage pipes in dredging wells require the excavation of deep trenches, resulting in a large amount of construction work and making it inconvenient to install drainage pipes due to the depth of the trenches.
[0005] This application provides a frost-proof drainage structure for a drainage well, including a drainage pipeline. The drainage pipeline is composed of multiple insulated pipes connected together, and multiple evenly distributed heating devices are provided on the drainage pipeline.
[0006] The heating device includes a pipe fitting connected to a drainage pipe, and the interior of the pipe fitting is provided with a heating structure for heating water.
[0007] Optionally, the heating structure consists of multiple electric heating tubes distributed along the axial direction of the pipe.
[0008] Optionally, the electric heating tube has a flat spiral structure, and the electric heating tube expands radially along the pipe fitting.
[0009] Optionally, the outer wall of the pipe fitting is covered with an insulation layer.
[0010] Optionally, there is a gap between the insulation layer and the pipe fitting;
[0011] The electric heating element also includes a terminal block, which passes through the pipe fitting and is sealed to the pipe fitting, and the terminal block extends into the gap;
[0012] All terminals are connected to wires, and the wires extend through the insulation layer to the outside of the insulation layer.
[0013] Optionally, both ends of the pipe fitting are connected to the insulation pipe via flange structures.
[0014] The antifreeze drainage structure for the dewatering well provided in this application consists of a drainage pipeline composed of multiple insulated pipes connected together. Multiple evenly distributed heating devices are installed on the drainage pipeline. Each heating device includes a fitting connected to the drainage pipeline, and the fitting contains a heating structure for heating the water. During use, the insulated pipes reduce the impact of the low external temperature environment on the water temperature. Simultaneously, as the water flows within the drainage pipeline, the multiple heating structures heat the water at multiple different locations within the pipeline, increasing the water temperature. This allows the drainage pipeline to be installed on the ground. With the combined action of the insulated pipes and heating structures, the water within the drainage pipeline can be prevented from freezing, achieving an antifreeze effect. This not only eliminates the need for trench excavation, reducing construction work, but also facilitates the installation of the drainage pipeline. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0022] like Figures 1-4 As shown:
[0023] An embodiment of this application provides a frost-proof drainage structure for a drainage well, including a drainage pipe 1. The drainage pipe 1 is composed of multiple insulated pipes 101 connected together, and multiple uniformly distributed heating devices 2 are provided on the drainage pipe 1.
[0024] In this embodiment, the insulation pipe 101 is existing technology and will not be described in detail.
[0025] The heating device 2 includes a pipe fitting 201 connected to the drain pipe 1, and the interior of the pipe fitting 201 is provided with a heating structure 202 for heating water.
[0026] Furthermore, the fitting 201 is located between the two insulation pipes 101, and both ends of the fitting 201 are connected to the insulation pipes 101 respectively.
[0027] In use, the drainage pipe 1 is installed on the ground (the installation method of the pipe on the ground is existing technology and will not be described in detail). When the temperature is low in winter, the heating structure 202 is activated, and water drawn from the drainage well enters the drainage pipe 1. As the water flows along the drainage pipe 1, the insulation pipe 101 blocks the heat exchange between the water and the external environment, reducing the impact of the low temperature environment on the water temperature. At the same time, multiple heating structures 202 heat the water at multiple different locations in the drainage pipe 1, increasing the water temperature in the drainage pipe 1, thereby preventing the drainage pipe 1 from freezing.
[0028] The antifreeze drainage structure for the drainage well provided in this embodiment is achieved by setting up a drainage pipeline 1 composed of multiple insulated pipes 101 connected together. The drainage pipeline 1 is equipped with multiple evenly distributed heating devices 2. The heating device 2 includes a pipe fitting 201 connected to the drainage pipeline 1. The pipe fitting 201 has a heating structure 202 for heating water inside. This allows the drainage pipeline 1 to be set on the ground during use. Under the combined action of the insulated pipes 101 and the heating structure 202, the water in the drainage pipeline 1 can be prevented from freezing, thus achieving the antifreeze effect of the drainage pipeline 1. This not only eliminates the need for trench excavation, reducing the amount of construction work, but also facilitates the installation of the drainage pipeline 1.
[0029] In some embodiments of this application, the heating structure 202 is composed of a plurality of electric heating tubes 203 distributed along the axial direction of the tube 201.
[0030] In this embodiment, the electric heating element 203 is prior art and will not be described in detail.
[0031] When in use, after water enters the pipe fitting 201, as it flows along the pipe fitting 201, multiple electric heating tubes 203 simultaneously heat the water inside the pipe fitting 201 to increase the water temperature.
[0032] In this embodiment, a solar cell power supply system is also included. The solar cell power supply system is connected to the electric heating tube 203, and the solar cell power supply system provides power to the electric heating tube 203. The solar cell power supply system is prior art and will not be described in detail.
[0033] In some embodiments of this application, the electric heating tube 203 has a flat spiral structure to increase the contact area between the electric heating tube 203 and the water. The electric heating tube 203 expands radially along the pipe fitting 201, so that the electric heating tube 203 can heat the water at multiple positions radially of the pipe fitting 201, thereby improving the heating effect.
[0034] In some embodiments of this application, the outer wall of the pipe fitting 201 is covered with an insulation layer 3 to reduce heat loss inside the pipe fitting 201.
[0035] In some embodiments of this application, there is a gap 4 between the insulation layer 3 and the pipe fitting 201.
[0036] The electric heating element 203 also includes a terminal block 204, which passes through the fitting 201 and is sealed and fixedly connected to the fitting 201, and extends into the gap 4. All terminal blocks 204 are connected to wires 5, which pass through the insulation layer 3 and extend to the outside of the insulation layer 3. The wires 5 are connected to the solar cell power supply system.
[0037] In this embodiment, a gap 4 is formed between the insulation layer 3 and the pipe fitting 201, and after the terminal block 204 of the electric heating tube 203 extends into the gap 4, the insulation layer 3 can not only insulate the inside of the pipe fitting 201, but also protect the terminal block 204 of the electric heating tube 203.
[0038] In some embodiments of this application, both ends of the pipe fitting 201 are connected to the insulation pipe 101 via flange structure 6, thereby facilitating the connection between the pipe fitting 201 and the insulation pipe 101.
[0039] In some embodiments of this application, those skilled in the art can design corresponding automatic control systems based on common knowledge in the art. The automatic control system monitors the water temperature inside the insulation pipe 101 through a temperature sensor, and automatically turns the electric heating tube 203 on or off according to the water temperature.
[0040] In this embodiment, the automatic control system is connected to the solar cell power supply system, and the solar cell power supply system supplies power to the automatic control system.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
