Description

Technical Field

[0001] This utility model relates to the technical field of cable shafts, specifically a cable shaft with a ventilation and heat dissipation structure. Background Technology

[0002] A cable is a conductor system used to transmit electricity or signals, typically consisting of multiple insulated conductors, a protective layer, and a shielding layer. It is widely used in modern society, primarily for energy transportation and information communication. During cable installation, cable shafts are commonly used. Cable shafts are vertical passage systems in buildings or underground facilities specifically designed for vertically laying cables. They are mainly used for centralized management and protection of the vertical routes of power and communication cables and are now widely used.

[0003] Most existing cable shafts are modular, consisting of multiple shaft sections assembled with bolts or flanges. Their specific structure generally consists of a shaft body and a front access door. The shaft body is a square cylindrical structure formed by four protective plates: front, rear, left, and right. The access door is located on the front protective plate, which facilitates cable installation and maintenance. During maintenance or repair, the internal structure can be accessed simply by opening the front access door.

[0004] Cable shafts are typically long, vertical shafts. When maintenance needs to be performed at a high location, maintenance personnel must use external objects, such as ladders, to increase their standing height. Maintenance work usually requires carrying various tools, but at heights, it's inconvenient to store these tools, limiting the number that can be carried. When tools need to be replaced, personnel must climb down to replace them, then climb back up to perform the maintenance, which is extremely cumbersome. Therefore, we offer cable shafts with ventilation and heat dissipation structures to solve these problems. Utility Model Content

[0005] 1) Technical problems to be solved This utility model proposes a cable shaft with a ventilation and heat dissipation structure. The top of the support plate is released from the fixing mechanism, and the flip plate is rotated outward by 90 degrees, so that the flip plate and the two support plates move to a horizontal state. The fixing between the two support plates is released by the locking mechanism, and the support plate is rotated by 180 degrees, so that the two support plates are placed on the two support mechanisms, thereby opening up the maintenance space in the middle and forming two support platforms on both sides. By placing excess maintenance tools on the support platforms, the need to climb up and down to change tools is avoided, thus achieving the purpose of convenient maintenance. This solves the problem that in the past, when tools needed to be changed, it was necessary to climb down to change them and then climb back up for maintenance, which was too cumbersome.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable shaft with a ventilation and heat dissipation structure, comprising a housing, wherein the side of the housing is provided with a plurality of heat dissipation holes for heat dissipation and ventilation, a flip plate is hinged to the inner wall of the housing, and two mutually separable support plates are rotatably connected to the outer surface of the flip plate, and a locking mechanism is provided between the two support plates for fixing the two support plates together; support mechanisms are provided on both sides of the housing for supporting the support plates; and a fixing mechanism is provided on the upper part of the housing for fixing the support plates to the housing.

[0008] Furthermore, the locking mechanism includes a plug rod, the outer surface of which is slidably connected to one of the support plates. One end of the plug rod is fixedly connected to a first spring, and the end of the first spring away from the plug rod is fixedly connected to the support plate. A circular hole is provided on the other support plate.

[0009] Furthermore, the support plate is also provided with a sliding groove, and a sliding block is slidably connected to the inner wall of the sliding groove. One side of the sliding block is fixedly connected to the insertion rod.

[0010] Furthermore, the support mechanism includes a fixed box, the outer surface of which is fixedly connected to the housing, and a support rod is slidably connected to the inner wall of the fixed box, with a pull block fixedly connected to one end of the support rod.

[0011] Furthermore, the fixing mechanism includes an outer clamping plate, a connecting shaft is fixedly connected to one side of the outer clamping plate, an inner clamping plate is fixedly connected to the end of the connecting shaft away from the outer clamping plate, and a rectangular groove is formed on the inner wall of the housing, the inner wall of the rectangular groove is slidably connected to the connecting shaft.

[0012] Furthermore, a second spring is fixedly connected to the upper surface of the outer card plate, and the upper end of the second spring is fixedly connected to the housing.

[0013] Furthermore, a rectangular plate is fixedly connected to the front of the housing, and the rectangular plate is located below the flip plate.

[0014] (iii) Beneficial effects: Compared with existing technologies, this cable shaft with ventilation and heat dissipation structure has the following advantages: 1. This cable shaft with ventilation and heat dissipation structure uses a fixing mechanism to release the top of the support plate, rotate the flip plate outward by 90 degrees, so that the flip plate and the two support plates move to a horizontal state. The fixing between the two support plates is released by the locking mechanism, and the support plate is rotated by 180 degrees, so that the two support plates are placed on the two support mechanisms, thereby opening up the maintenance space in the middle and forming two support platforms on both sides. By placing excess maintenance tools on the support platforms, the need to climb up and down to change tools is avoided, thus achieving the purpose of convenient maintenance. This solves the problem that when tools need to be changed, it is too cumbersome to climb down to change them and then climb back up to maintain them.

[0015] II. This cable shaft with ventilation and heat dissipation structure, through the setting of fixing mechanisms and other components, uses an outer clamping plate and an inner clamping plate to clamp the shell in the middle. It can move up and down through a rectangular groove. When it moves to the upper part, the support plate closes. After the top of the support plate moves to below the outer and inner clamping plates, the outer and inner clamping plates move downward to clamp the top of the support plate in the middle, thereby fixing the support plate and preventing it from opening. For higher stability, the outer clamping plate can also be fixed to the support plate with bolts. When needed, it can be opened by a second spring that gives the outer clamping plate a downward elastic force, so that the outer clamping plate is fixed to the support plate for a long time, which facilitates opening and closing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-6 As shown, this utility model provides a technical solution: a cable shaft with a ventilation and heat dissipation structure, including a housing 1. Multiple heat dissipation holes for ventilation are provided on the side of the housing 1. A flip plate 3 is hinged to the inner wall of the housing 1. Two mutually separable support plates 4 are rotatably connected to the outer surface of the flip plate 3. A locking mechanism 5 is provided between the two support plates 4 for fixing them together. Support mechanisms 6 are provided on both sides of the housing 1 for supporting the support plates 4. A fixing mechanism 7 is provided at the upper part of the housing 1 for fixing the support plates 4 to the housing 1. Bolt holes are provided at both ends to facilitate the connection of multiple housing sections 1 end to end. Ventilation openings 2 are used to increase the air circulation inside and outside the housing 1, thereby increasing the heat dissipation effect of the internal cables of the housing 1. A pin is connected to the flip plate 3, which is inserted into the inner wall of the housing 1 to enable the flip plate 3 to flip, thereby opening and closing the front of the housing 1. During normal use, the support plate 4 is used as the door of the working door to close the housing 1. During maintenance, the support plate 4 is opened and used as a support platform to support maintenance tools. The side of the support plate 4 used for support is roughened to increase friction.

[0021] The locking mechanism 5 includes a rod 501. The outer surface of the rod 501 is slidably connected to one of the support plates 4. One end of the rod 501 is fixedly connected to a first spring 502. The end of the first spring 502 away from the rod 501 is fixedly connected to the support plate 4. The other support plate 4 has a circular hole 505. The first spring 502 gives the rod 501 a force to slide outward, so that the rod 501 can be inserted into the circular hole 505. The two support plates 4 are connected by the rod 501 to prevent them from separating from each other.

[0022] The support plate 4 is also provided with a sliding groove 503. A sliding block 504 is slidably connected to the inner wall of the sliding groove 503. One side of the sliding block 504 is fixedly connected to the insertion rod 501. The side of the sliding block 504 near the outside is rough. Pushing the sliding block 504 can drive the insertion rod 501 to slide, thereby realizing the locking and separation between the two support plates 4.

[0023] The support mechanism 6 includes a fixed box 601. The outer surface of the fixed box 601 is fixedly connected to the shell 1. A support rod 602 is slidably connected to the inner wall of the fixed box 601. A pull block 603 is fixedly connected to one end of the support rod 602. By pulling the pull block 603, the support rod 602 can be slid outward to support the unfolded support plate 4.

[0024] The fixing mechanism 7 includes an outer clamping plate 701, a connecting shaft 702 fixedly connected to one side of the outer clamping plate 701, and an inner clamping plate 703 fixedly connected to the end of the connecting shaft 702 away from the outer clamping plate 701. A rectangular groove 704 is provided on the inner wall of the housing 1. The inner wall of the rectangular groove 704 is slidably connected to the connecting shaft 702. The outer clamping plate 701 and the inner clamping plate 703 clamp the housing 1 in the middle. The rectangular groove 704 allows it to move up and down. When it moves to the upper part, the support plate 4 closes. After the top of the support plate 4 moves to below the outer clamping plate 701 and the inner clamping plate 703, the outer clamping plate 701 and the inner clamping plate 703 move downward to clamp the top of the support plate 4 in the middle, thereby fixing the support plate 4 and preventing it from opening. If a higher degree of firmness is required, the outer clamping plate 701 and the support plate 4 can also be fixed together with bolts, and then opened when needed.

[0025] A second spring 705 is fixedly connected to the upper surface of the outer clamping plate 701. The upper end of the second spring 705 is fixedly connected to the housing 1. The second spring 705 gives the outer clamping plate 701 a downward elastic force, so that the outer clamping plate 701 is fixed to the support plate 4 for a long time.

[0026] A rectangular plate 8 is fixedly connected to the front of the housing 1. The rectangular plate 8 is located below the flip plate 3. When the flip plate 3 is opened, the rectangular plate 8 can support the flip plate 3 from below, keeping the flip plate 3 in a horizontal state and preventing it from flipping down too much.

[0027] Working principle: During use, the two support plates 4 are fixed together by the locking mechanism 5, and then the support plates 4 are fixed to the housing 1 by the fixing mechanism 7. The support plates 4 act as door panels for easy use. When maintenance is required, the top of the support plates 4 is released by the fixing mechanism 7, and the flip plate 3 is rotated outward by 90 degrees, so that the flip plate 3 and the two support plates 4 move to a horizontal state. The two support rods 602 are pulled out, and the fixing between the two support plates 4 is released by the locking mechanism 5. The support plates 4 are rotated by 180 degrees, so that the two support plates 4 are placed on the two support rods 602, thereby opening up the maintenance space in the middle and forming two support platforms on both sides. By placing excess maintenance tools on the support platforms, the need to climb up and down to change tools is avoided, thus facilitating maintenance.
