Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of radio and television wireless coverage, and particularly relates to a feeder protection device. BACKGROUND

[0002] Radio and television stations are usually located in high-altitude mountainous areas, and the machine room and the transmitting tower are at the same altitude, or the transmitting tower is set on the hill higher than the machine room. The signal output by the machine room is sent to the antenna on the transmitting tower through the feeder, and the radio and television signal is radiated through the antenna. The height of the transmitting tower is usually ten meters or even dozens of meters. In the ice and snow weather, the ice and snow on the transmitting tower will fall and hit the feeder directly below the transmitting tower. Once the feeder is damaged or deformed, many problems will occur, such as short circuit of the internal signal line and ground line of the feeder, too large standing wave ratio, low wireless transmission coverage quality, and even damage to the equipment in the machine room.

[0003] The feeder transmits the radio and television signal from the machine room to the transmitting tower under the support and protection of the support. In the existing application, the protection mode of the feeder is to install an inclined metal plate on the support, so that the ice and snow falls on the inclined metal plate and falls to the ground through the metal plate under the action of gravity. It is found in practice that the inclined metal plate cannot provide sufficient pressure dividing capacity and buffering capacity, resulting in insufficient impact resistance, and the feeder cannot be well protected, especially when the feeder in the bottom area of the transmitting tower is turned from the ground to be perpendicular to the ground.

[0033] The utility model will be further described below in connection with examples, but the utility model is not limited to these examples.

[0034] In the radio and television station, the radio and television signal of machine room emission reaches launch tower 2 along the hillside through feed pipe 3, and then goes up to antenna 4 along launch tower 2, and finally radiates through antenna 4. Since launch tower 2 is as high as ten or even dozens of meters, when ice and snow hit the feed pipe 3 of the bottom area of launch tower 2 under the action of gravity, it is easy to damage or deform the feed pipe 3, especially the bending area 5 formed when the feed pipe 3 turns from the ground to be perpendicular to the ground, which is neither parallel to the ground nor perpendicular to the ground, and is extremely easy to be damaged by ice and snow. The structure relation diagram of machine room, feed pipe 3, launch tower 2 and antenna 4 is shown in Fig. 1. The feed pipe 3 from the machine room to the launch tower 2 should be protected, whether it is on the ground, uphill or at the bottom of the tower, to prevent damage and avoid affecting the safe broadcast of radio and television. Figure 4

[0035] ​The utility model provides a kind of feeder protection device, including protective cover 1;The protective cover 1 includes first baffle 11, second baffle 12, first baffle 13, second baffle 14 and feeder out through-hole 15;The first baffle 11 and second baffle 12 structure are same;The first baffle 11 is quadrilateral;One long side of the first baffle 11 is fixedly connected with one long side of the second baffle 12, and the connecting place forms edge 16, and the first baffle 11, second baffle 12, horizontal plane constitute first protection body, and the section of the first protection body is triangle;The first baffle 13 and second baffle 14 structure are same;The first baffle 13 is quadrilateral;One long side of the first baffle 13 is fixed to another long side of the first baffle 11, and one long side of the first baffle 13 is perpendicular to horizontal plane;One long side of the second baffle 14 is fixed to another long side of the second baffle 12, and one long side of the second baffle 14 is perpendicular to horizontal plane;The first baffle 11, second baffle 12, first baffle 13, second baffle 14 constitute second protection body, and the section of the second protection body is pentagon;Feeder out through-hole 15 is set with one point on the edge 16 as center. Figure 1 As shown in the structural diagram of the protective cover 1 in the utility model.

[0036] The section of the first protection body is triangle, and the included angle (i.e. the top angle) between the first baffle 11 and the second baffle 12 in the triangle is in the range of 15°-45°. When ice and snow hit the protective cover 1, the edge 16 divides the ice and snow into two parts, and the ice and snow quickly slide off the first baffle 11 and the second baffle 12. The ice and snow slide off best when the top angle is in the range of 15°-45°, and the protective cover 1 has the least snow on the surface.

[0037] A hydrophobic coating is arranged on the outer surface of the metal layer 111, and the hydrophobic coating is polytetrafluoroethylene, a high-molecular compound formed by polymerization of tetrafluoroethylene. The hydrophobic coating has excellent chemical stability, corrosion resistance, sealing property, high lubrication and non-stickiness, electrical insulation and good aging resistance. The hydrophobic coating is arranged on the surface of the protective cover 1, which can effectively reduce the adhesion of ice and snow and prolong the service life of the protective cover 1.

[0038] On flat ground and uphill sections, the feeder 3 can enter from the front end of the second protection body and exit from the rear end. When the feeder 3 reaches the bottom of the launch tower 2, the feeder 3 can be arranged to exit from the feeder out through-hole 15 on the edge 16. Since the feeder out through-hole 15 is arranged on the edge 16, the feeder 3 can go straight up along the launch tower 2 after exiting from the through-hole, so that the bending area 5, which is the focus of protection, is completed inside the protective cover 1. Even if ice and snow fall, the ice and snow are divided by the edge 16 and flow backward by the first baffle 11 and the second baffle 12, so that the feeder 3 in the bending area 5 can be effectively protected.

[0039] Further, the first deflector 11 comprises a metal layer 111 and a buffer layer 112; the outer layer of the first deflector 11 is the metal layer 111, the inner layer of the first deflector 11 is the buffer layer 112, and the buffer layer 112 is fixedly installed on the metal layer 111. The metal layer 111 can be one of tungsten steel, titanium alloy or stainless steel, and stainless steel is the best choice considering the strength, corrosion resistance and price. The buffer layer 112 is hollow inside and is fixedly provided with more than one spring. When the impact force of ice and snow is too large, the spring of the buffer layer 112 is subjected to accumulation and generates elastic force to support the metal layer 111, so that the metal layer 111 is prevented from deforming or being damaged, thereby improving the impact resistance of the protective cover 1 and prolonging the service life of the protective cover 1.

[0040] Further, an electrothermal film layer 113 is arranged on the lower surface of the buffer layer 112, and an insulating protective layer is arranged on the upper and lower surfaces of the electrothermal film layer 113. Considering that in extremely cold weather, the surface of the protective cover 1 will be covered with thick ice and snow, the pressure resistance and impact resistance will be greatly weakened, and when the overloaded ice and snow on the launching tower 2 falls down, the protective cover 1 cannot effectively protect the feeder 3, therefore, the electrothermal film layer 113 and the insulating protective layer are arranged correspondingly to heat the protective cover 1 and melt the ice and snow on the surface of the protective cover 1, so as to maintain the protection ability. The structural diagram of the first deflector 11 is shown in Figure 2

[0041] Further, a temperature control unit is further included; the temperature control unit comprises a remote terminal and a protective cover end;

[0042] The remote terminal comprises a remote terminal controller module, a transmitting module, a setting module and a display module; the protective cover end comprises a protective cover end controller module, a receiving module, a temperature detection module, a switch control module and a power module;

[0043] The transmitting module is connected with the remote terminal controller module, and the transmitting module is wirelessly connected with the receiving module; the output end of the setting module is connected with the remote terminal controller module; the display module is connected with the remote terminal controller module;

[0044] The receiving module is connected with the protective cover end controller module; the output end of the temperature detection module is connected with the protective cover end controller module; the control end of the switch control module is connected with the protective cover end controller module, and the switch control module controls the on-off of the electrothermal film layer 113 and the power module; the power module provides power supply for the protective cover end controller module, the receiving module, the temperature detection module and the switch control module. The structural principle diagram of the temperature control unit is shown in Figure 3

[0045] ​​The temperature control unit is used in cooperation with the electric heating film layer 113. When the ice and snow are accumulated on the first guide plate 11 and the second guide plate 12, affecting the protection function of the protective cover 1, the temperature control unit can control the electric heating film layer 113 to heat and melt the accumulated ice and snow.

[0046] In the remote control terminal, the setting module is a keyboard, such as a 2*3 keyboard, which is used to set the start and stop of the protective cover end, the increase and decrease of the temperature, the increase and decrease of the timing, etc. The display module is a display, which is used to display the current temperature value of the protective cover end, the set temperature value, and the timing information, etc. The transmitting module corresponds to the receiving module of the protective cover end, which can be one of the wireless transmission such as Bluetooth, infrared, WiFi, etc. The temperature detection module installed in the inner cavity of the protective cover 1 is used to detect the environmental temperature, which is convenient for the remote control terminal to control the start and stop of the protective cover end, confirm the setting of the temperature, and set the timing length. The switch control module is a relay, which is used to connect the power module for the electric heating film layer 113 under the control of the controller module of the remote control terminal, and start heating. At the same time, the power module also provides power supply for each module of the protective cover end.

[0047] When the heating function of the electric heating film layer 113 is needed, the feed pipe out through hole 15 needs to be improved and processed at the same time to prevent the situation that the surface of the protective cover 1 is charged when melting snow: an insulating protective layer is arranged on the edge of the feed pipe out through hole 15. The insulating protective layer can effectively ensure that the protective cover 1 is not charged.

[0048] Further, the protective cover 1 further comprises a front baffle 17, a rear baffle 18, and a feed pipe in through hole 19; the front baffle 17 is fixedly installed on one side of the second protective body, and the rear baffle 18 is fixedly installed on the other side of the second protective body; the feed pipe in through hole 19 is arranged on the front baffle 17. When waterproofing is needed, the front baffle 17, the rear baffle 18, and the feed pipe in through hole 19 can be arranged as needed, so that the feed pipe 3 and other internal modules are protected from the sun, rain, and ice, prolonging the service life of the feed pipe 3 and other modules.

[0049] Since the feed pipe 3 reaches the transmitting tower 2 under the support of the support, the same number of fixing holes 110 can be symmetrically arranged on the first baffle 13 and the second baffle 14, and the fixing holes 110 are used to fix the protective cover 1 on the support by fixing members such as steel wires, which can reduce additional fixing costs and reduce costs.

[0050] In the electrical field, data detection, data processing, instruction control and execution necessarily involve computer programs, if the computer programs involved are prior art, external programs or simple calculation, comparison and control, the technical scheme should not be considered to involve the improvement of computer programs. The computer program involved in the temperature control unit of the utility model is simple detection and control, and does not involve the improvement of computer programs. In the utility model, it has been clearly indicated in the specification that the technical scheme is to provide a technical scheme for solving the problem of insufficient protection of the prior art, mainly for structural improvement, the auxiliary temperature control unit involves circuit and computer program, but the computer program is only simple detection, comparison and control, and the claim book also only applies for the protection of hardware structure accordingly. Therefore, the technical scheme of the utility model should not be identified as an unauthorized protection object.
