Description

Technical Field

[0001] The invention mainly relates to the technical field of fireproof bridges, and in particular to an anti-corrosion composite cable fireproof bridge. Background Art

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, grid trays and other structures. They are composed of brackets, supports and installation accessories. They can be erected independently or laid on various buildings (structures) and pipe gallery brackets. They have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance.

[0003] The fireproof bridge is mainly composed of a fireproof board made of glass fiber reinforced materials and inorganic adhesives, a metal frame and other fireproof substrates. The outer layer is added with fireproof coating. The fireproof bridge will not burn when it encounters fire, thereby blocking the spread of fire. It has extremely good fireproof and fire-retardant effects, and is fire-resistant, oil-resistant, corrosion-resistant, non-toxic, and pollution-free. It is easy to install as a whole, has a reasonable structure, a long service life, and is beautiful. The cable is installed in the cable bridge, and the environment is clean and easy to clean. The fireproof coating has the characteristics of thin coating, high fire resistance limit, and strong adhesion. The fireproof bridge is suitable for the laying of power cables below 10KV, as well as control cables, lighting wiring, and other indoor and outdoor overhead cable trenches and tunnels.

[0004] In the existing fireproof cable bridges, for example, the technical structure of the application document with application number 201920763630.2, includes a frame, a top cover is clamped on the top of the frame, a magnetic plate is embedded on the inner bottom side of the top cover, an iron frame is clamped on the top of the frame, a rubber plate is clamped on the bottom of the top cover, and a groove matching the frame is provided at the bottom of the rubber plate, and brackets are fixedly connected to the opposite sides of the inner wall of the frame by bolts, and the brackets are made of stainless steel at right angles. The anti-corrosion composite cable fireproof bridge protects the cables laid inside by the frame and the top cover, and uses the fireproof material of the frame itself for fireproofing. However, when a fire occurs, the bridge not only needs to be fireproof, but also needs to have better thermal insulation and heat dissipation capabilities. However, the existing bridge only has the function of fireproofing, and the solid bridge structure is easy to transfer heat, which causes the cables inside the bridge to be damaged due to high temperature during a fire. Summary of the invention

[0005] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the present invention mainly provides an anti-corrosion composite cable fireproof bridge to solve the technical problem raised in the above background technology that during a fire, the bridge is easy to transfer heat, causing the cables laid inside to be damaged due to excessive temperature.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] An anti-corrosion composite cable fireproof bridge, comprising a fireproof heat-conducting mechanism and a temperature sensor, wherein the fireproof heat-conducting mechanism comprises a bracket trough body and a bracket top cover, wherein the bracket top cover is located on the upper side of the bracket trough body, a folded edge fireproof plate is arranged on the outer wall of the bracket trough body, an anti-corrosion inner trough body is arranged on the bracket trough body, and a cavity is formed at the gap between the anti-corrosion inner trough body and the bracket trough body;

[0008] The first end piece and the second end piece are respectively provided at the two end positions of the bracket slot body, and seven through holes are provided on the first end piece and the second end piece, seven heat-conducting square tubes are provided between the first end piece and the second end piece, the seven heat-conducting square tubes are all located in the cavity, and the outer wall of the heat-conducting square tube fits with the groove on the cavity, and a plurality of air holes are linearly provided on the four surfaces of each of the heat-conducting square tubes at equal intervals, and connectors are provided at both ends of each of the heat-conducting square tubes, and the connectors are butt-jointed with the corresponding through holes, a support frame is provided in the opening position of the first end piece, a motor is provided on the support frame, a rotating blade is provided at the output end of the motor, and the motor and the temperature sensor are electrically connected, and the temperature sensor is mounted on one side of the inner wall of the cavity by bolts.

[0009] Furthermore, a sealing cover is provided at the opening position of the first end piece.

[0010] Furthermore, connecting protrusions are provided at the folding positions on both sides of the upper edge of the anti-corrosion inner trough body, each of the connecting protrusions is fitted and connected with a connecting groove, and two connecting grooves are respectively provided at the folding positions on both sides of the upper edge of the bracket trough body.

[0011] Furthermore, the bracket top cover is connected to the anti-corrosion inner tank body, the bracket tank body and the folded edge fireproof plate in sequence by bolts.

[0012] Furthermore, a cable laying assembly is arranged in the anti-corrosion inner tank, and the cable laying assembly includes two rectangular grooves, the two rectangular grooves are respectively arranged on both sides of the inner wall of the anti-corrosion inner tank, and a supporting mesh plate is commonly arranged on the two rectangular grooves.

[0013] Furthermore, a plurality of cable bearing seats are linearly arranged at equal intervals on the upper side of the support mesh plate, and a cable positioning cover is connected to the upper side of each cable bearing seat by bolts.

[0014] Furthermore, the upper side of the outer wall of the bracket top cover is a convex arc-shaped surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The present invention achieves that when a fire occurs, the folded edge fireproof board has a fireproof and flame-retardant effect by providing a support trough body, an anti-corrosion inner trough body and a folded edge fireproof board, and the bridge frame itself will not catch fire. The fireproof board is made of siliceous material and calcium material as main raw materials, and is added with flame retardant, foaming agent, carbonizing agent and high-temperature refractory material. Under high temperature conditions, a continuous foaming and expansion effect will occur to form a flexible sponge-like carbonized insulation layer, so that the supported bridge frame will not be softened and deformed sharply due to the action of high-temperature flames, and the strength will not drop sharply. In addition, the cavity between the anti-corrosion inner trough body and the support trough body is used to reduce the solid heat transfer capacity of the bridge frame itself, thereby reducing the heat transfer of the bridge frame itself. The weak heat transfer capability prevents rapid temperature rise around the cable and protects the cable. The first end piece, the through hole, the second end piece, the heat-conducting square tube, the air hole, the connector, the sealing cover, the motor and the rotating blade cooperate with each other to accelerate the air flow in the heat-conducting square tube when the cavity is at high temperature. Therefore, the air flow rate in the heat-conducting square tube is greater than the air flow rate outside the heat-conducting square tube. The air pressure outside the heat-conducting square tube is relatively large, which will press the hot air into the heat-conducting square tube and then spray it out from the through hole on the second end piece, quickly discharging the hot air in the cavity out of the fireproof bridge, effectively avoiding the rapid increase in temperature inside the bridge, further protecting the cable, and greatly reducing the chance of cable damage due to high temperature.

[0017] (2) The present invention achieves a close fit between the anti-corrosion inner trough body and the bracket trough body by setting connecting grooves and connecting protrusions, thereby improving the stability of the structure. The four structures of the bracket top cover, the anti-corrosion inner trough body, the bracket trough body and the folded edge fireproof plate can be connected together by bolts on the bracket top cover, thereby further improving the overall stability of the bridge frame. The structure is simple and easy to assemble, which reduces the installation difficulty of workers and has certain practical value. The upper side of the outer wall of the bracket top cover is an arc-shaped surface, which is not easy to accumulate water and can be used both indoors and outdoors.

[0018] (3) The cable support and the cable positioning cover of the present invention are provided to position the cable at multiple positions along the length direction of the cable, which is convenient for laying the cable. The rectangular groove and the supporting mesh plate cooperate with each other so that the cable is in an overhead state inside the bridge frame, which is not easily affected by moisture and corrosion, thereby extending the service life of the cable.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Example 1, please refer to the attached Figure 1-7As shown, an anti-corrosion composite cable fireproof bridge, including a fireproof heat-conducting mechanism 1 and a temperature sensor 3, the model of the temperature sensor 3 is SIN-P202, the fireproof heat-conducting mechanism 1 includes a bracket trough 11 and a bracket top cover 14, the bracket top cover 14 is located on the upper side of the bracket trough 11, the outer wall of the bracket trough 11 is provided with a folded fireproof plate 13, the bracket trough 11 is provided with an anti-corrosion inner trough 12, and the gap between the anti-corrosion inner trough 12 and the bracket trough 11 forms a cavity 15; the first end piece 16 and the second end piece 17 are respectively provided at the two ends of the bracket trough 11, and the first end piece 16 and the second end piece 17 are both provided with seven through holes 161, and the first end piece 16 and the second end piece 1 7 are provided between the first end piece 16, the seven heat-conducting square tubes 18 are all located in the cavity 15, and the outer wall of the heat-conducting square tube 18 fits with the groove on the cavity 15, and a plurality of air holes 181 are evenly spaced and linearly arranged on the four surfaces of each of the heat-conducting square tubes 18, and a connector 182 is provided at both ends of each of the heat-conducting square tubes 18, and the connector 182 is butt-jointed with the corresponding through hole 161, a support frame 162 is provided in the opening position of the first end piece 16, and a motor 191 is provided on the support frame 162, and a rotating blade 192 is provided at the output end of the motor 191, and the motor 191 and the temperature sensor 3 are electrically connected, and the temperature sensor 3 is installed on one side of the inner wall of the cavity 15 by bolts.

[0032] The above structure reduces the heat transfer capacity of the bracket slot 11 itself when a fire occurs through the fireproof heat conduction mechanism 1, and quickly discharges the hot air in the cavity 15 out of the fireproof bridge, effectively avoiding the rapid increase in temperature around the cables inside the bridge, protecting the cables, and reducing the probability of damage due to high temperature. The structure is simple and easy to assemble, which reduces the installation difficulty of workers and has certain practical value.

[0033] The specific operation is as follows: first, place the overall interface of the bridge frame on the pre-installed bracket, then place the cable in the arc-shaped recess on the cable bearing seat 23, then cover the cable positioning cover 24 on the cable bearing seat 23 by bolts, then cover the bracket top cover 14 on the anti-corrosion inner tank body 12, and connect the bracket top cover 14, the anti-corrosion inner tank body 12, the bracket tank body 11 and the folded edge fireproof plate 13 by bolts. When a fire occurs, when the temperature sensor 3 detects that the temperature in the cavity 15 is too high, the motor 191 is started, driving the rotating blades 192 to rotate, and the accelerated airflow enters the heat-conducting square tube 18 through the first end piece 16, accelerating the air flow in the heat-conducting square tube 18. Therefore, the air flow rate in the heat-conducting square tube 18 is greater than the air flow rate outside the heat-conducting square tube 18. The air pressure outside the heat-conducting square tube 18 is relatively large, which will press the hot air into the heat-conducting square tube 18, and then spray it out from the through hole 161 on the second end piece 17, quickly exhausting the hot air in the cavity 15 out of the fireproof bridge, effectively avoiding the rapid increase of the temperature inside the bridge.

Through the cable laying component 2, positioning at multiple positions along the length direction of the cable is achieved, which is convenient for laying. The upper side of the outer wall of the bracket top cover 14 is a convex arc surface, which is not easy to accumulate water and can be used both indoors and outdoors.
