Technical Field

[0001] The utility model relates to the technical field of electric power construction, and particularly relates to a new cable trench with a ventilation and heat dissipation function. Background Technique

[0002] With the rapid development of the power industry and the continuous expansion of the power grid scale, as an important carrier for power transmission, the safety and stability of cables are crucial for the operation of the entire power system. However, the traditional cable trench design often ignores the key factor of ventilation and heat dissipation, resulting in too high temperature inside the cable trench, which in turn causes a series of problems such as accelerated cable aging and decreased insulation performance, seriously threatening the safe operation of the power system.

[0003] Chinese Patent Publication No. CN206004273U discloses a power cable trench with ventilation and heat dissipation, which is provided with an intake fan and an exhaust fan controlled by a control circuit, further improving the ventilation and heat dissipation inside the cable trench, and keeping the ventilation and heat dissipation inside the cable trench in a good state through precise control.

[0004] However, in actual use of the above structure, since it is necessary to install filters on the intake fan and the exhaust fan to reduce the entry of dust, dust or garbage will adhere to and accumulate on the filter during long-term use. If the filter is not cleaned in time, it is easy to cause heat accumulation of the cables inside the cable trench, thereby affecting the service life of the cables. Content of the Utility Model

[0005] In view of the above problems, a new cable trench with a ventilation and heat dissipation function is provided, which solves the problem of dust or garbage accumulation on the filter through a heat dissipation box and a scraper.

The heat dissipation mechanism includes a heat dissipation box, a fan blade arranged inside the heat dissipation box, and a linkage scraping and cleaning mechanism for transmitting the rotational force of the fan blade. The new cable trench with a ventilation and heat dissipation function also includes a filter disassembly and removal mechanism for filtering dust arranged on the heat dissipation box.

[0007] Preferably, the linkage scraping and cleaning mechanism includes a rotary driver and a transmission rod; the rotary driver is arranged inside the heat dissipation box; the transmission rod is arranged at the output end of the rotary driver through a coupling.

[0009] Preferably, the linkage scraping and cleaning mechanism further includes a rotating block and a swinging block; the rotating block is arranged on the rotating rod and fixedly connected with the rotating rod coaxially; the swinging block is rotatably arranged on the mounting plate.

[0011] Preferably, the filtering and dismounting mechanism includes a filter net and a locking rod; the filter net is arranged on the heat dissipation box in a horizontal linear sliding direction; the locking rod is threadedly connected to the filter net.

[0012] The beneficial effects of the present utility model compared with the prior art are as follows:

Specific embodiments

[0027] In order to further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 - 5 As shown, a new type of cable trench with ventilation and heat dissipation functions includes a mounting plate 1, a cable placement plate 2 provided on the mounting plate 1 for placing cables, a closing plate 3 for closing and shielding the mounting plate 1, and a heat dissipation mechanism 4 for dissipating heat from the cables placed in the mounting plate 1. The heat dissipation mechanism 4 includes a heat dissipation box 41 and a fan blade 42 provided in the heat dissipation box 41, and a linkage scraping and cleaning mechanism 5 for transmitting the rotational force of the fan blade 42. The new type of cable trench with ventilation and heat dissipation functions further includes a filtering and dismounting mechanism 6 provided in the heat dissipation box 41 for filtering dust. A plurality of heat dissipation openings 11 for air passage are opened on the mounting plate 1. The cable placement plate 2 is threadedly connected to the mounting plate 1 through a threaded rod 12. A restricted placement groove 13 for separating cables is provided on the cable placement plate 2. A connecting pipe 14 is provided on the heat dissipation box 41, which penetrates through the mounting plate 1 and extends into the mounting plate 1.

[0029] When heat dissipation is required for the cables placed in the mounting plate 1, the rotary drive 51 is activated and drives the transmission rod 52 to rotate. When the transmission rod 52 rotates, the fan blade 42 can drive the air into the heat dissipation box 41. At this time, the air passes through the heat dissipation box 41 and the connecting pipe 14 and then enters the mounting plate 1, and dissipates heat from the cables placed in the mounting plate 1. When the transmission rod 52 rotates, it can drive the rotating rod 53 and the rotating block 55 to perform reciprocating tilting motions on the swinging block 56. When the swinging block 56 makes reciprocating tilting motions, the scraper 552 provided below can automatically scrape the filter net 61, and the dust and garbage on the filter net 61 can be automatically cleaned without manual cleaning. On the one hand, the heat dissipation effect of the cables placed in the mounting plate 1 can be maintained at all times, and on the other hand, the frequency of manual cleaning and replacement of the filter net 61 is reduced.

[0030] See Figures 6 - 8 As shown, the linkage scraping and cleaning mechanism 5 includes a rotary drive 51 and a transmission rod 52; the rotary drive 51 is arranged in the heat dissipation box 41; the transmission rod 52 is arranged at the output end of the rotary drive 51 through a coupling, and the transmission rod 52 is coaxially fixed with the fan blade 42 and is located below the filter net 61.

[0031] When heat dissipation is required for the cables placed in the limiting placement groove 13, first, the rotary drive 51 is activated, which then drives the transmission rod 52 connected through the coupling to rotate. When the transmission rod 52 rotates, the coaxially fixed fan blade 42 can be rotated, and then the air can enter through the heat dissipation box 41 and circulate in the mounting plate 1. At this time, heat dissipation work can be carried out on the cables placed in the mounting plate 1.

[0032] See Figures 8 - 9 As shown, the linkage scraping and cleaning mechanism 5 further includes a rotating rod 53 and a transmission belt 54; the rotating rod 53 is arranged on the heat dissipation box 41; the transmission belt 54 is sleeved on the transmission rod 52 and the rotating rod 53 respectively.

[0033] When the transmission rod 52 rotates, the rotational force can be transmitted to the rotating rod 53 through the transmission belt 54, and the rotating rod 53 is driven to rotate.

[0034] See Figure 9 As shown, the linkage scraping and cleaning mechanism 5 further includes a rotating block 55 and a swinging block 56; the rotating block 55 is arranged on the rotating rod 53 and is coaxially fixed with the rotating rod 53; the swinging block 56 is rotatably arranged on the mounting plate 1, a limiting block 551 is arranged on the rotating block 55, the limiting block 551 is cylindrical in shape, a mounting rod 561 for mounting the swinging block 56 is arranged on the mounting plate 1, and a scraper 552 for cleaning and scraping the dust or garbage on the filter net 61 is arranged below the swinging block 56.

[0035] When the rotating rod 53 rotates under the drive of the transmission belt 54, the rotating block 55 coaxially fixed on the rotating rod 53 can be driven to rotate synchronously, and when the rotating block 55 rotates, the swing block 56 can be driven to rotate and swing.

[0036] See also Figure 9 As shown, the linkage scraping and cleaning mechanism 5 further includes a linear limiting groove 57 ; the linear limiting groove 57 is provided on the swing block 56 , and the rotating block 55 is slidably matched with the linear limiting groove 57 .

[0037] When the rotating block 55 rotates, the limiting block 551 provided on the rotating block 55 can be driven to slide along the linear limiting groove 57 provided on the swinging block 56. During the continuous rotation of the rotating block 55, the limiting rod can be driven to slide along the linear limiting groove 57 provided on the swinging block 56. As a result, the swinging block 56 is driven to swing back and forth along the mounting rod 561 under the influence of the rotating block 55 and the linear limiting groove 57. During the swinging process, the scraper 552 is driven to slide on the filter screen 61 provided on the cooling box 41. Automatic cleaning can achieve the heat dissipation of the cables placed in the installation plate 1 at the same time. The transmission belt 54 can also drive the swing block 56 and the scraper 552 to synchronously rotate and scrape away the dust and garbage on the filter 61, so as to prevent the garbage from adhering to or blocking the filter 61 and affecting the air entry, resulting in poor heat dissipation effect, and can reduce the number of times the filter 61 is manually disassembled and cleaned. On the one hand, the heat dissipation effect of the cables placed in the installation plate 1 can be maintained at all times, and on the other hand, the frequency of manual cleaning and replacement of the filter 61 is reduced.

[0038] See also Figures 7 - 10 As shown, the filter disassembly mechanism 6 includes a filter screen 61 and a locking rod 62; the filter screen 61 is arranged on the heat sink 41 in a horizontal linear sliding direction; the locking rod 62 is threadedly connected to the filter screen 61, and the heat sink 41 is provided with a mounting hole 611 for the filter screen 61 to slide in a horizontal linear direction, and the heat sink 41 is also provided with a threaded mounting groove 612 for the locking rod 62 to be threadedly connected.

[0039] When the filter 61 needs to be disassembled and replaced, first rotate the locking rod 62 in the opposite direction until the locking rod 62 rotates and moves out of the outside of the threaded mounting groove 612, and then the filter 61 can be disassembled to the outside of the heat sink 41 for disassembly and maintenance. When the filter 61 needs to be installed, it only needs to be placed on the mounting hole 611 and the locking rod 62 is threaded into the threaded mounting groove 612, so that the filter 61 can be quickly installed, which simplifies the installation steps and operations. The opening of the mounting hole 611 makes it easy to quickly place the filter 61 on the heat sink 41, thereby facilitating the installation or disassembly of the filter 61.

[0040] The above embodiments merely represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
