Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation cover plates for cable bridges, and in particular relates to a ventilation cover plate structure for a cable bridge. Background Art

[0002] A ventilation cover is a structure installed above a concave cable tray, shielding the cables within and preventing falling dust and even rain in the event of a leak. It can be installed indoors or outdoors, but outdoor installations require higher levels of rain protection. To balance heat dissipation and rain protection, the cover features optional side vents.

[0003] Problems with existing technologies:

[0004] In order to dissipate heat outdoors, ventilation ducts are horizontally passed through the ventilation cover, and the circulating air can take away the heat in the cable tray. However, these ventilation ducts have a certain rigidity and it is difficult to stick to the cables in the cable tray, especially when the cables are laid in single, double, or triple strands, which is not conducive to heat dissipation of the adaptive cables. Utility Model Content

[0005] The utility model aims to provide a ventilation cover structure for a cable tray, which can guide air to flow close to the cable surface, and the air inlet port faces downward to prevent rainwater from entering, so as to adaptively dissipate heat from the cable and protect it from rain.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A ventilation cover structure for a cable tray comprises a metal shell, with metal folding plates fixed on both sides of the metal shell facing the same side. The two metal folding plates and the metal shell form a concave structure. Two elbows and a silicone tube connected between the two elbows are inserted transversely inside the concave structure. A silicone tube is connected between one end of the two elbows that are close to each other. The other ends of the two elbows extend downward through the adjacent metal folding plates. Stainless steel rings are bonded to the inside of the silicone tubes. The two metal folding plates are pulled outward to open the gap, and then moved downward to cover the cable tray, driving the silicone tube to fall into the cable tray. Under the action of the falling stainless steel ring, it can stick to the cables in the cable tray. While the metal shell closes the cable tray, the silicone tube is supported by the elbow to form a passage through the cable tray, guiding air to flow close to the surface of the cable. The air inlet port of the elbow faces downward to prevent rainwater from entering. The adaptive cable can dissipate heat while taking into account rain protection. It can also separate humid air from the cable and reduce the cable from getting wet.

[0008] As a preferred solution, metal baffles are welded on both sides of the metal shell, and the two metal baffles respectively face downward to cover the lower end of the bent pipe with the metal folding plate. The gaps between the two metal baffles and the adjacent metal folding plates are filled with a resin layer. The bent pipe is installed first, and then two metal baffles are installed. The metal folding plates are used to cover the bent pipe from both sides for protection, and then the resin layer is filled to reinforce the bent pipe, so that the bent pipe is more stable and can resist impact, bending, friction and the like during the installation of the ventilation cover structure.

[0009] As a preferred solution, the lower surface of the metal folding plate is threaded with a tightening bolt. After the metal folding plate is put on the folded edge of the trough-type cable tray, the tightening bolt is rotated forward until it presses against the folded edge and is locked under the action of friction, so that the trough-type cable tray is sealed more tightly. When disassembly is required, the tightening bolt can be reversed to disengage from the folded edge.

[0010] As a preferred solution, sealing gaskets are bonded to both ends of the metal shell, and both sides of the two sealing gaskets are folded toward the outside of the metal baffle. The two sealing gaskets are stacked to seal the gap at the connection between the two metal shells 1, and then they are glued firmly with waterproof glue to reduce rainwater leakage into the gap.

[0011] As a preferred solution, a plurality of alloy support plates are fixed at intervals on the sides of the two metal folding plates away from each other, and the alloy support plates are fixedly connected to the lower edge of the metal baffle along the interval between two adjacent elbows.

[0012] As a preferred solution, rubber gaskets are bonded to the sides of the two metal folding plates that are close to each other, and the two rubber gaskets are arranged under the bent pipe. When the metal folding plates buckle the folded edges, they drive the rubber gaskets downward and tightly against the trough-type cable tray, closing the edge seams and further improving the rainproof performance.

[0013] As a preferred solution, a lifting ring is welded on the upper surface of the metal shell, and a distance is left between the lifting ring and the metal folding plate. Each metal shell is equipped with four lifting rings, which can be lifted with a rope and a crane, or lifted with a steel pipe passed through the lifting ring. This way of moving can avoid applying force to the two metal folding plates, keeping the two metal folding plates in a free state, making it convenient to pull them apart in an "eight" shape by hand.

[0014] The technical effects achieved by this utility model are:

[0015] This utility model pulls the two metal folding plates outward to open the gap, then moves them downward to enclose the cable tray, driving the silicone tube into the cable tray. Under the action of the falling stainless steel ring, it can adhere to the cables in the cable tray. While the metal shell encloses the cable tray, the curved tube supports the silicone tube, forming a passage through the cable tray, guiding air to flow close to the cable surface. The curved tube's air inlet port faces downward to prevent rain from entering. This adaptive cable dissipates heat while providing rain protection, and also separates humid air from the cables, reducing the risk of cables getting wet.

[0016] The utility model first installs the bent pipe, then installs two metal baffles, cooperates with the metal folding plates to cover the bent pipe from both sides for protection, and then fills the resin layer to reinforce the bent pipe, making the bent pipe more stable and able to resist impact, bending, friction and the like during the installation of the ventilation cover structure.

[0024] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0025] Cable trays are devices used to carry and protect cables and are widely used in a variety of fields, including construction, electricity, and communications. For example, trough-type cable trays consist of a series of parallel troughs with right-angled sides that fold over to form slide rails. These neatly place cables within the troughs, providing excellent support and protection, making them suitable for locations with low cable capacity and smaller spans. Especially when installed outdoors, cable trays require high levels of rainproofing while also taking into account heat dissipation. Therefore, we improved upon traditional ventilation covers and created a rainproof and heat-dissipating ventilation cover structure for this trough-type cable tray.

[0026] like Figure 1-Figure 5 As shown, a ventilation cover structure of a cable tray includes a metal shell 1, and metal folding plates 2 are fixed on both sides of the metal shell 1 facing the same side. The lower edges of the two metal folding plates 2 are three-folded and used to fasten the two side edges of the opening of the concave cable tray. The two metal folding plates 2 and the metal shell 1 are surrounded by a concave structure, and two bent pipes 3 and a silicone tube 4 connecting the two bent pipes 3 are inserted horizontally inside the concave structure. The silicone tube 4 is connected between one end of the two bent pipes 3 that are close to each other, and the other ends of the two bent pipes 3 extend downward through the adjacent metal folding plates 2, and stainless steel rings 5 ​​are bonded to the inside of the silicone tubes 4.

[0027] Furthermore, the height of the lower edge of the metal folding plate 2 is smaller than the height of the bent pipe 3, which makes it convenient for the staff to pull in an eight-shaped pattern to both sides to open the gap between the two metal folding plates 2 and to cover the folded upper edge of the trough-type cable tray.

[0028] Furthermore, in this embodiment, the length of the silicone tube 4 is greater than the width of the metal shell 1 and can be bent inside the metal shell 1. At the same time, the number of stainless steel rings 5 ​​is preferably five, which are used to drop the silicone tube 4 from different positions.

[0029] Through the above structure, its working principle is: pull the two metal folding plates 2 outward to open the distance, then move down to cover the cable tray, drive the silicone tube 4 to fall into the cable tray, and under the falling action of the stainless steel ring 5, it can stick to the cables in the cable tray.

[0030] While the metal shell 1 encloses the cable tray, the silicone tube 4 is supported by the curved pipe 3 to form a passage that penetrates the cable tray, guiding the air to flow close to the cable surface, and the air inlet port of the curved pipe 3 faces downward to prevent rain from entering. The adaptive cable can dissipate heat and protect against rain, and can also separate humid air from the cable, reducing the cable from getting wet.

[0031] like Figure 4 As shown, when laying double-strand cables inside the trough-type cable tray, the cables are separated, and the silicone tube 4 is dropped through the stainless steel ring 5 so that the silicone tube 4 bends toward both sides on the upper surface of the cable to cover the outer surface of the cable as much as possible.

[0032] like Figure 5 As shown, when three cables are laid inside the trough-type cable tray, the cables are separated, and the silicone tube 4 is dropped through the stainless steel ring 5 so that the silicone tube 4 bends to both sides on the upper surface of the cable. The premise for this is that the cable spacing must be reserved so that multiple cables can all get heat dissipation.

[0033] Refer to the attached Figure 2 and Figure 3 , metal baffles 6 are welded on both sides of the metal shell 1, and the two metal baffles 6 respectively cover the lower end of the bent pipe 3 downward with the metal folding plate 2. The gaps between the two metal baffles 6 and the adjacent metal folding plates 2 are filled with a resin layer 7. The bent pipe 3 is installed first, and then two metal baffles 6 are added. The metal folding plates 2 cover the bent pipe 3 from both sides for protection, and then the resin layer 7 is filled to reinforce the bent pipe 3, so that the bent pipe 3 is more stable and can resist impact, bending, friction and the like during the installation of the ventilation cover structure.

[0034] Refer to the attached Figure 1 、 Figure 2 and Figure 3 The lower surface of the metal folding plate 2 is threaded with a tightening bolt 8. After the metal folding plate 2 is put on the folded edge of the trough type cable tray, the tightening bolt 8 is turned forward until it is pressed against the folded edge and locked under the action of friction, making the trough type cable tray more tightly sealed. When disassembly is required, the tightening bolt 8 can be reversed to disengage from the folded edge.

[0035] Refer to the attached Figure 1 and Figure 2 Sealing gaskets 9 are bonded to both ends of the metal shell 1. Both sides of the two sealing gaskets 9 are folded toward the outside of the metal baffle 6. The two sealing gaskets 9 are stacked to seal the gap at the connection of the two metal shells 1, and then glued with waterproof glue to reduce rainwater leakage into the gap.

[0036] Refer to the attached Figure 1 and Figure 2 A plurality of alloy support plates 10 are fixed at intervals on the side of the two metal folding plates 2 away from each other. The alloy support plates 10 are fixedly connected to the lower edge of the metal baffle 6 along the interval between two adjacent bent pipes 3. The number of alloy support plates 10 is adjusted with the number of bent pipes 3. For example, if the number of bent pipes 3 is ten, the number of alloy support plates 10 is twelve, or if the number of bent pipes 3 is fourteen, the number of alloy support plates 10 is sixteen. In this way, there are always two alloy support plates 10 clamping the bent pipes 3 from both sides, and they also support the resin layer 7 upward, fully separating the bent pipes 3, so that the air flow is relatively isolated.

[0037] Refer to the attached Figure 2 and Figure 3The two metal flaps 2 are close to each other and are bonded with rubber pads 11 on one side, and the two rubber pads 11 are arranged below the elbow pipe 3, when the metal flaps 2 hold the folded edge, the rubber pads 11 are driven to tightly adhere to the groove type cable bridge downwards, the edge seam is closed, and the rainproof performance is further improved.

[0038] Referring to the drawings Figure 1 and Figure 3 The upper surface of the metal shell 1 is welded with lifting rings 12, and the lifting rings 12 and the metal flaps 2 are spaced apart, and in the embodiment, four lifting rings 12 are provided for each metal shell 1, and a rope can be used in cooperation with a crane for lifting, or a steel pipe is passed through the lifting ring 12 to lift, so that the metal shell 1 is moved, the force is not applied to the two metal flaps 2, the two metal flaps 2 are kept in a free state, and the two metal flaps 2 are conveniently pulled apart in an eight-shaped manner.

[0039] The working principle of the utility model is as follows: when working, the two metal flaps 2 are pulled apart to open the interval, and then the cable bridge is covered downwards, the silica gel pipe 4 falls into the cable bridge, and under the falling action of the stainless steel ring 5, the cable in the cable bridge can be adhered.

[0040] At the same time that the metal shell 1 closes the cable bridge, the silica gel pipe 4 is supported by the elbow pipe 3 to form a through path through the cable bridge, air is guided to flow close to the surface of the cable, and the air inlet end of the elbow pipe 3 is downward to prevent rainwater from entering, and the cable is self-adapted to heat dissipation and rainproof, and can also separate the humid air from the cable to reduce the cable that is wetted.

[0041] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
