Description

Technical Field

[0001] The present invention relates to the technical field of waterproofing for building structures, and particularly to a dehumidification system based on electroosmotic pulses and a dehumidification method thereof. Background Art

[0002] With the rapid development of society, there are more and more various buildings, which are also getting taller and taller. However, most of the underground space development technologies are in the initial stage. In real life, water seepage often occurs in the underground layer. When water seeps through the walls or other structures of the underground layer, it is likely to cause problems such as damp and mildew, and further make the air in the environment where people are located turbid, reducing the quality of people's daily life. In addition, serious water seepage will also bring other disadvantages, such as corroding buildings or steel bars, increasing maintenance costs, and shortening the structural life of buildings.

[0003] Currently, the common methods for preventing water seepage include: building an elevated floor and using the method of sandwich wall construction, using asphalt rolls or polypropylene fiber cloth for auxiliary construction, and using high-power dehumidifiers or central air conditioners for the dehumidification system based on electroosmotic pulses. Among the above traditional methods, building an elevated floor and using the method of sandwich wall construction only simply achieves the effect of reducing the intrusion of moisture, which will result in a relatively large market loss of the building; the method of using asphalt rolls or polypropylene fiber cloth for auxiliary construction is simple and rough in construction, and it can prevent water but not moisture; using high-power dehumidifiers or central air conditioners for the dehumidification system based on electroosmotic pulses only reduces the moisture content in the air and has no protective effect on the building structure.

[0041] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0042] In people's daily lives, there are many scenarios that require dehumidification and moisture removal to ensure that the corresponding structures and facilities are not corroded or damaged by moisture, thereby avoiding such situations from affecting people's normal lives. The dehumidification system and its dehumidification method based on electroosmotic pulses provided by the present invention can be applied to various types of building structures, such as basements, etc., and can also be applied to other building structures other than basements. For example, other places such as tunnels, bridges, and hydroelectric power stations. It should be noted that the present invention does not specifically limit a certain application place. The dehumidification system and its dehumidification method based on electroosmotic pulses provided by the present invention are applicable to all building structures that are mainly composed of porous materials such as bricks, water, and concrete, whether new or old, large or small, for residential or other uses. Specifically, the present invention will be described by taking a basement as an example.

[0043] Embodiment 1

[0044] This embodiment provides a dehumidification system based on electroosmotic pulses, including:

[0045] An anode wire, which is buried in the wall of the structure to be measured and is used to conduct a positive current to the wall of the structure to be measured;

[0046] A cathode rod, which is inserted into the soil at a set distance from the wall of the structure to be measured and is used to form a pulse circuit with the anode wire;

[0047] The positive electrode current monitoring module is used to generate a positive electrode current according to a monitoring instruction and send it to the anode wire, and is also used to obtain the changing current data in the circuit and send the changing current data to the comparison circuit;

[0048] The comparison circuit is used to compare the changing current data with a preset threshold value, obtain the drying information of the structure to be measured according to the comparison result, and send the drying information to the host;

[0049] The host is used to generate a monitoring instruction, and is also used to receive the drying information and optimize the monitoring instruction according to the drying information;

[0050] The positive electrode current monitoring module is connected to the anode wire and the comparison circuit. The positive electrode current monitoring module is connected to the host through a communication cable. The anode wire and the cathode rod form a pulsed circuit loop.

[0051] The above dehumidification system based on electroosmotic pulse utilizes the electroosmotic principle, combines pulsed electricity, and uses a safe low voltage to make the water molecules in the porous medium migrate directionally under the action of an electric field, which can solve the waterproof and moisture-proof problems of the underground layer of a building.

[0052] It should be noted that in another feasible embodiment, the above anode wire can also be buried in the ground or top surface of the structure to be measured. The present invention does not limit the specific position where the anode wire is buried, but it should be emphasized that whether the anode wire is buried in the wall, ground or top surface of the structure to be measured belongs to the protection scope of the present invention.

[0053] As a preferred implementation manner of this embodiment, the monitoring instruction generated by the host includes the time for generating a positive current. Specifically, the host receives the drying information and optimizes the monitoring instruction according to the drying information. Specifically, the host adjusts the time for generating a positive pulse current according to the real-time drying degree of the structure to be measured, for example, shortens the corresponding time, or pauses generating a positive pulse current. That is, the frequency and magnitude of the positive pulse are adjusted to prevent excessive dehydration and cracking from affecting the structure to be measured.

[0054] In another feasible embodiment, when the above dehumidification system based on electroosmotic pulse is applied to different void levels, it can not only reduce the water content to achieve the dehumidification function, but also prevent water intrusion to achieve the anti-seepage function. Its specific purpose depends on the void level.

[0055] As a preferred implementation manner of this embodiment, the anode wire and the cathode rod form a pulsed circuit loop, and the dehumidification system based on electroosmotic pulse includes several groups of pulsed circuit loops. In the present invention, dehumidification and moisture removal are carried out by adopting a pulsed current-based method, such as Figure 2As shown, by inserting the anode wire into the wall of the basement to be measured and inserting the cathode rod into the soil at a set distance from the wall of the basement to be measured, a pulsed electric field can be provided on both sides of the porous medium (the wall, floor or ceiling of the basement to be measured). Under the action of this pulsed electric field, the water in the medium will move towards the cathode along the direction of the electric field, thus playing a drying role.

[0056] Specifically, each anode wire and a cathode rod form a pulsed circuit loop. It is sufficient to install the same pulsed loop on the same wall of the basement to be measured. Installing one pulsed loop on each different wall can better dehumidify each wall of the entire basement to be measured.

[0057] In this embodiment, the cathode rod is inserted into the soil 3 - 5 feet from the ground. It should be noted that the present invention does not limit this. In different usage scenarios, the distance at which the cathode rod is inserted into the soil can also be adjusted to a certain extent.

[0058] As a preferred implementation manner of this embodiment, the anode wire uses conductive plastic as the material, and the negative electrode rod uses copper metal as the material. In this embodiment, the anode wire is buried, which can enhance the service life of the anode.

The IN - pin of the amplification chip U1 is connected to one end of the capacitor C6, and the IN + pin of the amplification chip U1 is connected to the other end of the capacitor C6.

[0066] Specifically, through the above amplification, the spike waves in the circuit can be filtered out, and the data information passing through here can be amplified, ensuring the stability of information transmission.
