DETAILED DESCRIPTION

[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] See also Figure 1-3The present embodiment provides a steel bridge deck wet interface rapid drying device, including a movable drying frame 1 and a plurality of drying components, the drying frame 1 includes a plurality of drying brackets 101 connected in sequence transversely, the plurality of drying brackets 101 are matched with a plurality of drying components in a one-to-one correspondence, any drying component is arranged in the corresponding drying bracket 101, the length of the drying frame 1 is the same as the width of the steel bridge deck; it also includes a control module 2, a hot air pump 3 and a hot air pipe 4, the drying component includes a drying valve 5 and a drying shell 6, the drying shell 6 is wrapped and arranged in the corresponding drying bracket 1 01, the drying shell 6 and the drying bracket 101 jointly form a drying space, and the plurality of drying spaces are sealed with each other. An output port is provided on the top of the drying shell 6, and the output port is communicated with the drying space. A drying valve 5 is sealed and arranged at the connection between the output port and the drying space. The control module 2 is connected to the plurality of drying valves 5 in communication. The hot air pump 3 is arranged on any drying bracket 101, and the hot air pump 3 is provided with an air inlet and an air outlet, and the air inlet is communicated with the external environment. The hot air pipe 4 is provided with an air inlet end and a plurality of air outlet ends, and the plurality of air outlet ends correspond to the plurality of drying shells 6 one by one. Matching, any air outlet end is interconnected with the output port of the corresponding drying shell 6, the air inlet end is interconnected with the air outlet, the control module 2 is communicated with the hot air pump 3, this scheme is provided with a hot air pump 3, a plurality of drying spaces and a plurality of drying valves 5, a plurality of drying valves 5 are matched with a plurality of drying spaces one by one, any drying valve 5 is sealed in the corresponding drying space, the hot air pump 3 is communicated with the corresponding drying space through the drying valve 5, the control module 2 realizes the drying treatment of the corresponding drying space by controlling the opening and closing of the drying valve 5, and the device of this scheme controls the opening or closing of the corresponding drying valve 5 according to the humidity level of various parts of the steel bridge located in the drying frame 1, thereby increasing the output power of the hot air pump 3 to the remaining drying spaces, which solves the traditional fire drying method for drying the steel bridge deck. The principle of the fire drying method is to evaporate the water on the surface of the steel bridge by directly heating the air. Since the humidity level is inconsistent at various places in the transverse direction of the steel bridge, and the fire drying method cannot adjust its own output power according to the humidity level at various places of the steel bridge, it is easy to cause the problem of fuel waste.

[0033] Furthermore, the drying frame 1 of the present scheme also includes moving wheels 7 and peripheral seals 8. The moving wheels 7 are arranged at the bottom of the drying frame 1, so that the drying frame 1 of the present scheme has the ability to move, which is conducive to drying various parts of the steel bridge; in addition, the peripheral seal 8 is arranged around the bottom of the drying frame 1, the top end of the peripheral seal 8 is connected to the bottom of the drying frame 1, and the bottom end of the peripheral seal 8 is arranged in contact with the surface of the steel bridge. Such an arrangement ensures that the internal space of the drying frame 1 is isolated from the external space.

[0034] Furthermore, the drying frame 1 of the present scheme also includes a plurality of internal seals 9, and there is a connecting space between two adjacent drying brackets 101. The plurality of connecting spaces are matched one-to-one with the plurality of internal seals 9. Any internal seal 9 is sealed in the corresponding connecting space. The internal seal 9, the peripheral seal 8 and the drying shell 6 together form a drying space. The present scheme realizes the formation of a drying space by providing an internal seal 9, and the internal seal 9, the peripheral seal 8 and the drying shell 6 together.

[0035] In addition, the present scheme also includes a plurality of diffuse reflection laser radars 10, and the plurality of diffuse reflection laser radars 10 are matched one-to-one with the plurality of dry spaces. Any diffuse reflection laser radar 10 is arranged in the corresponding dry space. The diffuse reflection laser radar 10 includes a signal generating module 11 and a refraction signal receiving module 12. The signal generating module 11 is used to transmit a signal toward the steel bridge deck position in the dry space, and the refraction signal receiving module 12 is used to receive the refraction signal reflected back. The present scheme is provided with a signal generating module 11 to detect the moisture condition of the steel bridge deck position in the corresponding dry space, and transmit the moisture condition to the refraction signal receiving module 12. It is worth mentioning that the signal emitted by the signal generating module 11 of the present scheme is inconsistent when passing through a position where there is water on the steel bridge deck and a position where there is no water on the steel bridge deck. Based on this, the refraction signal receiving module 12 can determine whether there is water on the steel bridge deck at that position according to the angle of the received signal.

[0036] Specifically, when the present solution detects that the higher the moisture level of the steel bridge deck in the dry space, the larger the opening degree of the corresponding dry valve 5 will be. Such a setting can quickly dry the wet surface of the steel bridge deck in the dry space, and the moisture level of the steel bridge deck in the dry space of the present solution is positively correlated with the opening degree of the corresponding dry valve 5. Based on this, the control module 2 of the present solution pre-inputs the maximum opening degree D of the dry valve 5 and the moisture level W of the steel bridge deck in the dry space paired with the maximum opening degree D of the dry valve 5. The refraction signal receiving module 12 is used to detect the moisture level W0 of the steel bridge deck in the corresponding dry space in real time, and upload the data to the control module 2. The control module 2 calculates the opening degree S of the dry valve 5 based on the data, and controls the valve port of the dry valve 5 for adjustment; wherein, S=W0 / W×D+e, e is a correction function, and D≥e≥0.

[0037] In addition, since the application occasion of the device of this scheme is on the steel bridge deck at sea, and because sea fog often appears at sea, in fact, a large amount of sea salt will be mixed in the sea fog. After the sea fog adhering to the steel bridge deck is dried by the device, sea salt will remain on the steel bridge deck. If these sea salts are not removed in time, the anti-corrosion layer laid on the steel bridge deck will cause the anti-corrosion layer to crack or fall off from the steel bridge deck. Based on this, the diffuse reflection laser radar 10 of this scheme also includes a frequency signal receiving module 13, and the frequency signal receiving module 13 is used to receive the reflected frequency signal. When the signal emitted by the signal generating module 11 of this scheme passes through the position where there is sea salt residue on the steel bridge deck and the position where there is no sea salt residue on the steel bridge deck, the reflected frequencies of the two are inconsistent. The frequency signal receiving module 13 determines whether there is sea salt residue in the corresponding area of ​​the steel bridge deck based on the received frequency signal.

[0038] When it is detected that there is sea salt residue at the position of the steel bridge deck, in order to remove the sea salt, the same end of the peripheral seal 8 of this scheme is provided with a plurality of slots, and the plurality of slots are matched one by one with the plurality of drying spaces, and any slot is connected with the corresponding drying space, and also includes a cold air pump 15, which is arranged outside the drying frame 1, and the cold air pump 15 is provided with a cold air inlet and a cold air outlet, the cold air inlet is connected with the external environment, and the cold air outlet is arranged beside the plane formed by the plurality of slots, and the cold air pump 15 blows the cold air from the slot at one end of the peripheral seal 8 to the steel bridge near the slot at the other end of the peripheral seal 8 edge of the surface; it is worth noting that, since the cold air pump 15 adopted in this scheme uses the external environment as the air source, that is to say, the air blown out by the cold air pump 15 also carries sea salt, the wind of the cold air pump 15 cannot be blown into the drying space, otherwise the sea fog in the external environment will be blown into the drying space. Based on this, the cold air pump 15 of this scheme is arranged outside the drying frame 1, and the cold air pump 15 blows air in front of each slot, so that a pressure difference is formed between the inside and the outside of each drying space, so that the dry sea salt in the drying space will be sucked out to the outside due to the pressure difference.

[0039] Furthermore, in order to ensure that the air blown out by the cold air pump 15 does not enter the various drying spaces, the present solution also includes a plurality of inclined plates 14, and the plurality of inclined plates 14 are matched one-to-one with the plurality of notches. One end of any inclined plate 14 is connected to one end of the corresponding notch, and the other end of the inclined plate 14 and the other end of the notch form an opening. The direction of the opening formed by the inclined plate 14 and the notch is not connected to the cold air outlet of the cold air pump 15. Such a setting prevents the air blown out by the cold air pump 15 from directly entering the drying space. Instead, due to the pressure difference between the inside and outside of the drying space, the dried sea salt in the drying space is sucked out of the drying space.

[0040] In the above embodiment, it is mentioned that the cold air pump 15 is provided to blow air outside the drying space to create a pressure difference between the inside and outside of the drying space, so that the sea salt in the drying space is sucked out of the drying space due to the pressure difference. However, in actual situations, the sea salt on the steel bridge deck in the drying space is not completely dried and adheres to the steel bridge deck, so that the sea salt cannot be sucked out of the drying space. Therefore, when the moisture level of the steel bridge deck in the drying space is close to dryness, the corresponding drying valve 5 cannot be completely closed at this time, and the hot air pump 3 still needs to transmit the hot air to the corresponding drying space through the drying valve 5; on the one hand, it is to continue to dry the nearly dry wet surface of the steel bridge deck in the drying space; on the other hand, it is to blow air toward the steel bridge deck in the drying space, so that the sea salt adhered to the steel bridge deck floats, and then the floating sea salt will be sucked out due to the pressure difference between the inside and outside of the drying space, further ensuring that the sea salt in the drying space is sucked out;

[0041] Specifically, the frequency signal receiving module 13 of this solution detects that the area of ​​sea salt on the steel bridge deck in the dry space is H0, and uploads the data to the control module 2. When the control module 2 pre-enters e=D, the area of ​​sea salt on the steel bridge deck in the dry space is H, and the control module 2 calculates the value of e according to the data, and controls the valve opening of the drying valve 5 for adjustment; wherein, e=H0 / H×D. Through such a setting, the opening degree of the drying valve 5 will also be affected by the content of sea salt on the steel bridge deck in the dry space. It should be noted that the value range of S in this solution is [0, D]. When the control module 2 calculates S≥D, S=D is taken.

[0042] A method for quickly drying a wet interface of a steel bridge deck comprises the following steps:

[0043] S1: The control module 2 controls the drying valve 5 to open;

[0044] S2: The control module 2 controls the hot air pump 3 to start working;

[0045] S3: The hot air passes through the hot air pipe 4 and reaches the corresponding drying space to dry the corresponding steel bridge deck;

[0046] S4: After the corresponding steel bridge deck has completed the drying process, the control module 2 controls the corresponding drying valve 5 to close.

[0047] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
