Description

Technical Field

[0001] The present invention relates to the technical field of cable bridges, in particular to a composite cable bridge. Background Art

[0002] Composite cable trays combine the strengths of metal and plastic, offering excellent conductivity, corrosion resistance, and strength. Composite materials also possess high stiffness and stability, maintaining their shape and size in harsh environments. The emergence of composite cable trays represents an innovative attempt to achieve better performance and higher efficiency through a combination of materials.

[0003] Based on the above description of existing composite cable trays, although composite cable trays have stronger corrosion resistance and pressure resistance, as well as higher strength and rigidity compared to traditional cable trays, they still have defects in actual use, such as:

[0004] As the high and low temperature weather changes, the cable heat dissipation requirements also change. However, the existing composite cable tray is not convenient for adaptively adjusting the vent size according to the cable heat dissipation requirements. Therefore, it is necessary to provide a composite cable tray to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a composite cable tray to solve the problem in the above background technology that the existing cable tray is not convenient for adaptively adjusting the size of the vents according to the heat dissipation requirements of the cables. The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a composite cable tray, comprising a tray body, a fireproof plate installed at the bottom inner side of the tray body, and a heat-conducting rod connected to the joint of the fireproof plate, an air collecting box provided above both ends of the tray body, and a slider provided inside the air collecting box, an installation groove provided inside the slider, an adjustment mechanism connected to the inside of the installation groove, a filter plate provided on one side above the air collecting box, a sealing plate connected above the filter plate, and an axle rod installed below the sealing plate.

[0007] In a further embodiment, a first ball bearing is provided on the inner side of the bridge body, and a threading mechanism is also installed on the inner side of the bridge body.

[0008] In a further embodiment, the first ball and the bridge body form a rolling structure.

[0009] In a further embodiment, the threading mechanism includes a fixed sleeve installed at the bottom inner side of the bridge body, and a movable rod is slidably connected to the inner side of the fixed sleeve, and first springs are connected to both ends of the movable rod.

[0010] In a further embodiment, the fixing sleeve, the movable rod and the first spring are all arc-shaped.

[0011] In a further embodiment, a brush is installed above the outer side of the slider, and the end of the brush contacts one side of the filter plate.

[0012] In a further embodiment, the adjustment mechanism includes a telescopic sleeve rod arranged inside the installation groove, and the inner side of the telescopic sleeve rod is connected to a second spring, and the end of the telescopic sleeve rod is inlaid with a second ball.

[0013] In a further embodiment, a torsion spring is installed on the outer side of the end of the shaft, and an opening and closing plate is connected to the outer side of the shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention is provided with a threading mechanism, which utilizes a fixed sleeve, a movable rod and a first spring, and cooperates with the elastic action of the first spring to enable the cable to move up and down during the threading process. Compared with the existing technology, on the one hand, the threading mechanism can be conveniently applied to cables of different diameters, and on the other hand, it can straighten relatively curved cables and restrain the straightened cables at the same time, thereby avoiding the problem that the cables passing through the inside of a wire trough run into the inside of another wire trough during the threading and laying process, resulting in the cables being laid in an interlaced manner on the inside of the corresponding wire trough.

[0016] 2. The present invention is provided with an adjustment mechanism. When a higher temperature is generated inside the bridge body, the temperature will be introduced to the inside of the gas collecting boxes on both sides through the heat-conducting rod. When the hot air inside the gas collecting box becomes more and more, it will push the slider to move upward until the top of the slider hits the sealing plate. When the heat continues to increase, the expanding hot air will push the telescopic sleeve and the second ball on one side of the slider to extend to one side in cooperation with the elasticity of the second spring, so that the opening and closing plates can be pushed outward and flipped in cooperation with the shaft rod and the torsion spring. Since the temperature inside the bridge body is constantly changing and the opening order of the opening and closing plates is from top to bottom, the adjustment mechanism can control the number of openings of the opening and closing plates according to the temperature inside the bridge body. Compared with the existing technology, this setting can adaptively adjust the number of air outlets according to the temperature changes inside the bridge body, thereby increasing the practicality and adaptability of the bridge body during use.

[0017] 3. The present invention is provided with a brush. When the slider rises, it can also drive the brush to scrub the filter plate, and the dust scrubbed off is guided to the outside of the opening and closing plate in the open state through the inclined surface above the slider, thereby effectively scrubbing and cleaning the filter plate.

[0018] 4. The present invention is provided with an adjustment mechanism. In low temperature weather, the heat dissipation demand on the inside of the bridge body is not high, and the cables on the inside of the bridge body have low working efficiency at extremely low temperatures. At this time, the cold air on the outside can be isolated by the closed opening and closing plate, and at the same time, it can also have a good thermal insulation effect on the cables on the inside of the bridge body.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 The present invention provides an embodiment: a composite cable bridge, comprising a bridge body (1), a fireproof plate (2) installed at the bottom inner side of the bridge body (1), and a heat-conducting rod (102) plugged into the joint of the fireproof plate (2), a gas collecting box (4) is provided above both ends of the bridge body (1), and a slider (5) is provided inside the gas collecting box (4), and a mounting groove (6) is provided inside the slider (5), characterized in that an adjustment mechanism (7) is connected to the inner side of the mounting groove (6), and a filter plate (8) is provided on one side above the gas collecting box (4), a sealing plate (9) is connected above the filter plate (8), and a shaft (10) is installed below the sealing plate (9).

[0028] Example 1, please refer to Figure 1-2 and Figure 5 : A first ball (101) is provided on the inner side of the bridge body (1), and a threading mechanism (3) is also installed on the inner side of the bridge body (1), the first ball (101) and the bridge body (1) form a rolling structure, the threading mechanism (3) includes a fixed sleeve (301) installed on the bottom of the inner side of the bridge body (1), and a movable rod (302) is slidably connected to the inner side of the fixed sleeve (301), and the two ends of the movable rod (302) are connected to the first spring (303), and the fixed sleeve (301), the movable rod (302) and the first spring (303) are all in an arc shape;

[0029] When laying cables of various functions, the cables are sequentially passed through the inner bottom of the corresponding bridge body (1), the inner side of the threading mechanism (3) composed of the fixed sleeve (301) and the movable rod (302), and the threads are threaded in cooperation with the two first balls (101) at the inner bottom of the threading mechanism (3). A first spring (303) is provided on the inner side of the fixed sleeve (301). Through the provision of the first spring (303), the cable can be moved up and down under the elastic action of the first spring (303) during the threading and laying process. This provision can, on the one hand, facilitate the threading mechanism (3) to be applicable to cables of different diameters, and on the other hand, can straighten relatively curved cables and bind the straightened cables, thereby avoiding the problem that the cables passing through the inner side of the cable trough run into the inner side of another cable trough during the threading and laying process, i.e., the cables are laid in an interlaced manner in the corresponding cable troughs.

[0030] Example 2, please refer to Figure 1 and Figure 4 , which is different from Example 1 in that: a brush (501) is installed above the outer side of the slider (5), and the end of the brush (501) is in conflict with one side of the filter plate (8);

[0031] When the slider (5) rises, it can also drive the brush (501) to scrub the filter plate (8), and the dust scrubbed off is guided to the outside of the opening and closing plate (1002) in the open state through the inclined surface above the slider (5), thereby effectively scrubbing and cleaning the filter plate (8).

[0032] Please refer to Example 3 Figure 1 、 Figure 3 and Figure 5 , which is different from Example 2 in that: the adjustment mechanism (7) includes a telescopic sleeve (701) arranged on the inner side of the installation groove (6), and the inner side of the telescopic sleeve (701) is connected to a second spring (702), the end of the telescopic sleeve (701) is embedded with a second ball (703), the outer side of the end of the shaft (10) is installed with a torsion spring (1001), and the outer side of the shaft (10) is connected to an opening and closing plate (1002);

[0033] In hot weather, the cables laid inside the bridge body (1) have a high heat dissipation demand and generate a high temperature inside the bridge body (1). The temperature will be introduced to the inside of the gas collecting boxes (4) on both sides through the heat conducting rod (102). When the heat inside the gas collecting boxes (4) reaches a certain amount, it will push the slider (5) to move upward until the top of the slider (5) hits the sealing plate (9). As the heat inside the bridge body (1) continues to increase, the expanded heat will extend to one side from the telescopic sleeve (701) and the second ball (703) on one side of the slider (5) in conjunction with the elasticity of the second spring (702), so that the opening and closing plate (1002) can be pushed outward and flipped in conjunction with the shaft (10) and the torsion spring (1001). The order of opening the opening and closing plates (1002) is from top to bottom, and the number of openings of the opening and closing plates (1002) is mainly controlled by the temperature inside the bridge body (1). For details, please refer to Figure 6 This arrangement can adaptively drive the gear position of the regulating mechanism (7) according to the temperature change inside the bridge body (1), thereby increasing the practicality and adaptability of the bridge body (1) during use.

[0034] Working principle: When laying cables of various functions, the cables are sequentially passed through the inner bottom of the corresponding bridge body (1), the inner side of the threading mechanism (3) composed of the fixed sleeve (301) and the movable rod (302), and the two first balls (101) at the inner bottom of the threading mechanism (3) are used for threading. A first spring (303) is provided on the inner side of the fixed sleeve (301). Through the provision of the first spring (303), the cable can be moved up and down under the elastic action of the first spring (303) during the threading and laying process. This provision can, on the one hand, facilitate the threading mechanism (3) to be applicable to cables of different diameters, and on the other hand, can straighten relatively curved cables and bind the straightened cables, thereby avoiding the problem that the cables passing through the inner side of the cable trough run into the inner side of another cable trough during the threading and laying process, i.e., the cables are laid in an interlaced manner in the corresponding cable troughs.

[0035] In hot weather, the cables laid inside the bridge body (1) have a high heat dissipation demand and generate a high temperature inside the bridge body (1). The temperature will be introduced to the inside of the gas collecting boxes (4) on both sides through the heat conducting rod (102). When the heat inside the gas collecting boxes (4) reaches a certain amount, it will push the slider (5) to move upward until the top of the slider (5) hits the sealing plate (9). As the heat inside the bridge body (1) continues to increase, the expanded heat will extend to one side from the telescopic sleeve (701) and the second ball (703) on one side of the slider (5) in conjunction with the elasticity of the second spring (702), so that the opening and closing plate (1002) can be pushed outward and flipped in conjunction with the shaft (10) and the torsion spring (1001). The order of opening the opening and closing plates (1002) is from top to bottom, and the number of openings of the opening and closing plates (1002) is mainly controlled by the temperature inside the bridge body (1). For details, please refer to Figure 6 This arrangement can adaptively drive the gear position of the regulating mechanism (7) according to the temperature change inside the bridge body (1), thereby increasing the practicality and adaptability of the bridge body (1) during use;

[0036] When the slider (5) rises, it can also drive the brush (501) to scrub the filter plate (8), and the dust scrubbed off is guided to the outside of the opening and closing plate (1002) in the open state through the inclined surface above the slider (5), thereby effectively scrubbing and cleaning the filter plate (8);

[0037] In low-temperature weather, the heat dissipation demand inside the bridge body (1) is not high, and the cables inside the bridge body (1) have low working efficiency at extremely low temperatures. At this time, the closed opening and closing plate (1002) can be used to isolate the cold air outside, while also achieving a good heat preservation effect on the cables inside the bridge body (1).
