Description

Technical Field

[0001] This invention relates to a fire-resistant sealing and protection process system for sling anchor cups, and more specifically to an intelligent central control system for dehumidifying bridge anchor cups. Background Technology

[0002] The applicant's earlier utility model patent CN 217974042 U discloses a fire-resistant sealing protective cover for a sling anchor cup and its sling anchor cup protection system; it includes a sealing cover body; the sealing cover body is a cylindrical body with openings at both ends; the inner surface of the sealing cover body has a sealing fire-resistant layer; the sling anchor cup protection system includes the above-mentioned fire-resistant sealing protective cover, the sealing cover body is sealed and fixed to the outside of the sling anchor cup, and an isolation gap is formed between the sealing cover body and the sling anchor cup; it also includes a dehumidification system for introducing dry gas into the isolation gap, and the sealing cover body has an inlet valve and an exhaust valve for introducing dry gas.

[0003] In the above patented technologies, in order to introduce dry gas into the isolation gap, a dehumidifier and related pipelines are provided in the bridge deck maintenance passage at the lowest point of the main cable in the middle span. After the dehumidification pipeline is connected to the dehumidifier, it extends along the fork-shaped ear plate at the bottom of the suspender cable towards the main towers on both sides. The dry air with a slight positive pressure in the dehumidification pipeline is sent to the upper part of the sealing cover body. The dry air flows from the top to the bottom inside the sealing cover body and is discharged through the exhaust valve at the bottom, taking away the humid air inside the sealing cover body. This ensures that the air humidity inside the sealing cover body is kept below 45%, thereby achieving dehumidification protection for the bottom of the suspender cable and the suspender cable anchor cup.

[0004] However, there are many anchor cup protective covers on bridges. It would be a waste to equip each cover with a dehumidifier. Therefore, how to unify the anchor cup protective covers on the entire bridge to achieve unified ventilation and dehumidification and thus achieve coordinated control is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides an intelligent central control system for dehumidifying bridge anchor cups, aiming to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An intelligent central control system for dehumidifying bridge anchor cups includes an anchor cup and a protective cover fitted over the outside of the anchor cup. The protective cover has an air inlet and an exhaust outlet for introducing drying gas. The system also includes a drying ventilation module and a central control module.

[0008] The drying and ventilation module includes a main ventilation pipe and a dehumidifier connected to the inlet of the main ventilation pipe; the main ventilation pipe has multiple branch ventilation pipes, each of which is connected to the air inlet of the protective cover; a first three-way solenoid valve is installed at the connection point between the main ventilation pipe and the branch ventilation pipe, and a second three-way solenoid valve is installed at the end of the branch ventilation pipe near the air inlet;

[0009] The main control module is electrically connected to the signal control terminals of the dehumidifier, the first three-way solenoid valve, and the second three-way solenoid valve.

[0010] Through the above technical solution, the intelligent master control system provided by the present invention uses a dehumidifier for unified dehumidification control. By using the cooperation of the first three-way solenoid valve and the second three-way solenoid valve, the main ventilation pipe and the branch ventilation pipe can be dehumidified first. After the moisture in the main ventilation pipe and the branch ventilation pipe is removed, the inner cavity of the protective cover is dehumidified, which has a better dehumidification effect.

[0011] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, an on / off solenoid valve is installed on the exhaust port of the protective cover, and the on / off solenoid valve is electrically connected to the control module. When dehumidification is required, the on / off solenoid valve is opened to facilitate the discharge of moisture.

[0012] Preferably, in the above-mentioned intelligent control system for dehumidifying bridge anchor cups, a one-way valve is installed at the end of the branch ventilation pipe near the first three-way solenoid valve, and the one-way valve prevents gas from flowing back into the main ventilation pipe.

[0013] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, a first humidity sensor is installed inside the protective cover, and a second humidity sensor is installed on the branch ventilation pipe. The second humidity sensor is located between and close to the first three-way solenoid valve and the second three-way solenoid valve. The first humidity sensor detects the humidity inside the protective cover, providing early warning of when dehumidification is needed and detecting when dehumidification is complete. The second humidity sensor detects the humidity inside the pipe, ensuring that moisture is removed from the pipe before dehumidifying the inside of the protective cover.

[0014] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, both the air inlet and the exhaust outlet are located at the bottom of the protective cover, and respectively on both sides of the bottom of the protective cover. The air inlet and exhaust outlet can form a cycle from bottom to top and then from top to bottom, ensuring the dehumidification effect.

[0015] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, the air inlet is connected to an extension pipe, the bottom end of which is connected to the branch ventilation pipe, and the top end of which is located in the upper part of the inner cavity of the protective cover. This allows the drying gas to be blown from top to bottom throughout the entire interior of the protective cover.

[0016] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, both the first three-way solenoid valve and the second three-way solenoid valve are three-position three-way solenoid directional valves. The inlet and one outlet of the first three-way solenoid valve are connected to the main venting pipeline, and the other outlet of the first three-way solenoid valve is connected to the branch venting pipeline; the inlet and one outlet of the second three-way solenoid valve are connected to the branch venting pipeline, and the other outlet of the second three-way solenoid valve is connected to the outside. Selecting three-position three-way solenoid directional valves facilitates control and meets usage requirements.

[0017] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, the control module controls the dehumidifier's activation and the switching of the first and second three-way solenoid valves to introduce dry gas into the inner cavity of the protective cover. The dehumidification modes of the control module include a gradual dehumidification mode and a directional dehumidification mode. Dehumidification can be selected according to different dehumidification needs to meet those requirements.

[0018] Preferably, in the aforementioned intelligent control system for dehumidifying bridge anchor cups, the progressive dehumidification mode involves sequentially introducing dry gas into multiple protective covers in an arranged order, while the directional dehumidification mode involves introducing dry gas into the protective cover requiring dehumidification as needed. Selecting different dehumidification modes enables comprehensive dehumidification and protection of the anchor cups, resulting in better performance.

[0019] Preferably, in the above-mentioned intelligent control system for dehumidifying bridge anchor cups, the dehumidification and ventilation method of any of the protective covers is as follows: after the dehumidifier is turned on, the first three-way solenoid valve is controlled to connect the main ventilation pipeline to the corresponding branch ventilation pipeline, and the second three-way solenoid valve is controlled to connect the branch ventilation pipeline to the outside; then the second three-way solenoid valve is controlled to connect the branch ventilation pipeline to the inner cavity of the protective cover. The intelligent control system provided by this invention can ensure the dryness of the pipeline before the protective cover is dehumidified, balancing the advantages and disadvantages of overall integrated dehumidification, with a simpler structure and more convenient control.

[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an intelligent central control system for dehumidification of bridge anchor cups, which has the following beneficial effects:

[0021] 1. The intelligent central control system provided by the present invention uses a dehumidifier for unified dehumidification control. By using the cooperation of the first three-way solenoid valve and the second three-way solenoid valve, the main ventilation pipe and the branch ventilation pipe can be dehumidified first. After the moisture in the main ventilation pipe and the branch ventilation pipe is removed, the inner cavity of the protective cover is dehumidified, which has a better dehumidification effect.

[0022] 2. The intelligent central control system provided by this invention can ensure the dryness of the pipeline before the protective cover dehumidifies, balancing the advantages and disadvantages of overall joint control dehumidification, with a simpler structure and more convenient control.

[0023] 3. This invention can select dehumidification according to different dehumidification needs to meet those needs; selecting different dehumidification modes can achieve comprehensive dehumidification protection for the anchor cup, resulting in better performance. Attached Figure Description

[0039] The main control module 4 is electrically connected to the signal control terminals of the dehumidifier 32, the first three-way solenoid valve 34, and the second three-way solenoid valve 35.

[0040] To further optimize the above technical solution, an on / off solenoid valve 23 is installed on the exhaust port 22 of the protective cover 2, and the on / off solenoid valve 23 is electrically connected to the main control module 4.

[0041] To further optimize the above technical solution, a one-way valve 36 is installed at the end of the branch ventilation pipe 33 near the first three-way solenoid valve 34. The one-way valve 36 prevents gas from flowing back into the main ventilation pipe 31.

[0042] To further optimize the above technical solution, a first humidity sensor 37 is installed inside the protective cover 2, and a second humidity sensor 38 is installed on the branch ventilation pipe 33. The second humidity sensor 38 is located between the first three-way solenoid valve 34 and the second three-way solenoid valve 35, and is close to the second three-way solenoid valve 35.

[0043] To further optimize the above technical solution, both the air inlet 21 and the exhaust outlet 22 are located at the bottom of the protective cover 2, and are located on both sides of the bottom of the protective cover 2 respectively.

[0044] To further optimize the above technical solution, the air inlet 21 is connected to an extension pipe 24, the bottom end of the extension pipe 24 is connected to the branch ventilation pipe 33, and the top end of the extension pipe 24 is located in the upper part of the inner cavity of the protective cover 2.

[0045] To further optimize the above technical solution, the first three-way solenoid valve 34 and the second three-way solenoid valve 35 are both three-position three-way solenoid directional valves.

The inlet and one outlet of the second three-way solenoid valve 35 are connected to the branch vent line 33, and the other outlet of the second three-way solenoid valve 35 is connected to the outside.

[0046] To further optimize the above technical solution, the main control module 4 controls the opening of the dehumidifier 32 and the switching of the first three-way solenoid valve 34 and the second three-way solenoid valve 35 to allow dry gas to enter the inner cavity of the protective cover 2; the dehumidification modes of the main control module 4 include progressive dehumidification mode and directional dehumidification mode.

The second three-way solenoid valve 35 is controlled to connect the branch vent pipe 33 to the outside environment to dehumidify the pipes. Then, when the second humidity sensor 38 detects that the humidity meets the requirements, the second three-way solenoid valve 35 is controlled to connect the branch vent pipe 33 to the inner cavity of the protective cover 2 for dehumidification. When the first humidity sensor 37 detects that the inner cavity of the protective cover 2 meets the requirements, the dehumidification of one anchor cup is completed. Then, the dehumidification of the next segment of pipes and anchor cups is performed.

[0050] When the directional dehumidification mode is selected, that is, when the first humidity sensor 37 detects that the humidity inside a certain protective cover 2 is too high, the above-mentioned method is used to dehumidify the inner cavity of the protective cover 2.

[0051] The gradual dehumidification mode is determined based on the data values ​​detected jointly by the first humidity sensor 37 and the second humidity sensor 38, or it can be based primarily on the detection value of the first humidity sensor 37.
