Description

Technical Field

[0001] The invention relates to the field of pole towers, and in particular to a windproof and defrosting pole tower structure. Background Art

[0002] A communication tower is a tall structure equipped with communication antennas. It is characterized by its high structure. Conventional communication towers are mainly composed of steel components such as tower bodies, platforms, lightning rods, ladders, antenna supports, etc. They are mainly used for the transmission and emission of microwave, ultra-short wave, and wireless network signals.

[0003] Currently, most communication towers are installed outdoors. When extreme weather occurs, steel structures such as antenna supports are prone to risks of being blown off or toppled. When strong wind warnings occur around communication towers, it is impossible to respond in time.

[0004] For example, China Patent Publication No. 1, a smartly manufactured high-strength windproof mobile communication signal tower, was published on April 23, 2021, and is named "A mobile communication tower". It includes a base, and the internal movably connected base is equipped with an installation shaft. Through a spiral fixing platform, the contact area between the plug-in rod and the outside is increased, and the grip of the plug-in rod is improved, so that the signal tower can be firmly fixed. The reinforced steel improves the lateral strength and wind resistance of the signal tower. A counterweight block is arranged on the outside of the mounting seat to prevent the signal tower from falling to one side when hit by strong winds, thereby enhancing the wind resistance of the signal tower. When strong winds hit, the buffer spring can buffer and filter the impact force of the strong wind. At the same time, the inclined rod drives the movable block to compress the rubber air spring, thereby increasing the buffering and reducing the rigid impact of strong winds on the signal tower.

[0005] The disadvantages of the existing patents are: (1) the antenna installed on the upper part of the tower is prone to being blown off or toppled over in strong wind conditions, which increases the maintenance cost; (2) when a strong wind alarm occurs around the tower, it is impossible to take protective measures in time and there is no wind protection equipment. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the antenna arranged on the upper part of the tower body is easily blown off or damaged in strong wind conditions, and to provide a windproof and defrosting pole tower structure with a windproof device to protect the antenna from affecting the communication effect in strong wind conditions.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A windproof and defrosting tower structure, comprising:

[0009] A tower body, wherein an antenna is provided on the outer side wall of the upper end of the tower body;

[0010] A windproof device, the windproof device includes an installation box arranged on the outer side wall of a tower body, a fan module arranged in the installation box, and a driving device for driving the motor, the installation box includes an upper installation box and a lower installation box, the antenna is located between the upper installation box and the lower installation box, the fan module includes a first fan arranged in the upper installation box, and a second fan arranged in the lower installation box, the first fan vertically supplies air downward to form a wind curtain, and the antenna is located in the wind curtain.

[0011] The upper installation box and the lower installation box are sleeved on the outer wall of the tower body. The first fan arranged in the upper installation box sends air vertically downward to form a wind curtain, and the antenna is located in the wind curtain. When strong wind occurs, the fan module in the installation box is started to form a wind curtain from top to bottom outside the antenna, which isolates the antenna from the strong wind outside the wind curtain and reduces the damage to the antenna caused by strong wind.

[0012] Preferably, an upper air supply port is provided on the lower side plate of the upper installation box, an upper air inlet is provided on the upper side plate of the upper installation plate, and the first fan is located between the upper air inlet and the upper air supply port.

[0013] In the upper installation box, the first fan draws natural wind into the first fan from the upper air inlet, and the first fan then vertically supplies air downward from the upper air outlet to form a wind curtain.

[0014] Preferably, a lower air inlet is provided on the upper side plate of the lower installation box, and the second fan is located below the lower air inlet, and the second fan supplies air toward the tower body.

[0015] When the first fan is started, the second fan in the lower installation box is started, and the wind of the wind curtain and the natural wind are drawn into the lower installation box from the lower air inlet through the second fan, so that a wind curtain barrier is formed on the outside of the antenna, blocking the damage to the antenna by strong external wind and reducing the subsequent manual maintenance costs.

[0016] Preferably, the upper air supply port and the lower air inlet are arranged opposite to each other in the vertical direction.

[0017] The upper air supply port and the lower air inlet are arranged opposite to each other in the vertical direction, so that an air curtain is formed vertically downward, and the airflow direction is controllable.

[0018] Preferably, the lower air inlets are distributed in a circle according to the central axis of the tower body, the antennas correspond to the lower air inlets one by one, and the antennas are located on the inner side of the relative lower air inlets.

[0019] The antenna corresponds to the lower air inlet one by one and is located on the inner side of the lower air inlet. The upper air outlet and the lower air inlet are vertically opposite to each other. Therefore, the antenna corresponds to the upper air outlet one by one, so that the air flow velocity of the wind curtain outside the antenna is the strongest, and the wind curtain barrier corresponding to the outside of the antenna is the most stable.

[0020] Preferably, a sleeve is sleeved on the outer wall of the tower body between the upper installation box and the lower installation box, and an annular channel is formed between the sleeve and the outer wall of the tower body, and the annular channel passes through the upper installation box and the lower installation box.

[0023] A heating module is provided in the lower installation box, and the heating module is heated under the driving device. The second fan supplies air toward the heating module, and the airflow enters the annular channel after being heated by the heating module, so that the airflow in the annular channel has a certain temperature.

[0024] Preferably, the side wall of the sleeve is provided with regularly distributed air holes, and the air holes penetrate the outer side of the sleeve and the annular channel.

[0025] The heated air flow flows through the annular channel, and is supplied to the space inside the upper mounting box and the lower mounting box from the air holes on the side wall of the sleeve. The air flow has temperature, and a wind curtain is formed on the outside of the antenna, so that the temperature inside the wind curtain is higher than the temperature outside the wind curtain. The heated air flow flows through the antenna, so that the antenna can be defrosted and de-iced when the temperature drops or in extreme weather, without affecting the communication effect of the antenna. The wind curtain blocks the air flow outside to form a barrier, so that heat is not easily lost over a large area, thereby reducing the energy loss of the heating module.

[0026] Preferably, a lightning rod is provided on the upper end of the tower.

[0027] Therefore, the present invention has the following beneficial effects: (1) The antenna installed on the pole tower is provided with a windproof device to prevent the antenna from being blown off or damaged in strong wind conditions, thereby reducing the labor maintenance cost; (2) In cooling or extremely cold weather conditions, the area around the antenna can be defrosted and de-iced without affecting the communication effect of the antenna.

[0034] In order to make the purpose, technical scheme and advantages of the technical solution embodiments of the present invention clearer, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In the embodiment shown, a windproof and defrosting tower structure comprises:

[0036] A tower body 1, wherein an antenna 2 is provided on the outer side wall of the upper end of the tower body 1;

[0037] A windproof device, the windproof device includes an installation box arranged on the outer wall of the tower body 1, a fan module arranged in the installation box, and a driving device for driving the motor, the installation box includes an upper installation box 3 and a lower installation box 4, the antenna 2 is located between the upper installation box 3 and the lower installation box 4, the fan module includes a first fan 5 arranged in the upper installation box 3, and a second fan 6 arranged in the lower installation box 4, the first fan 5 vertically sends air downward to form a wind curtain, and the antenna 2 is located in the wind curtain.

[0038] The upper installation box 3 and the lower installation box 4 are sleeved on the outer wall of the tower body 1. The first fan 5 arranged in the upper installation box 3 vertically sends air downward to form a wind curtain, and the antenna 2 is located in the wind curtain. When strong winds appear, the fan module in the installation box is started, and a wind curtain is formed from top to bottom outside the antenna 2, which isolates the antenna 2 from the strong wind outside the wind curtain, thereby reducing the damage to the antenna 2 caused by the strong wind.

[0039] The windproof and defrosting pole tower structure described in the above embodiment forms a wind curtain by means of a first fan 5 arranged in an upper mounting box 3 and a second fan 6 arranged in a lower mounting box 4. The antenna 2 is located in the formed wind curtain, and adapts to the strong wind conditions outside by adjusting the speed of the fan module. This solves the problem that the antenna 2 arranged on the upper part of the tower body 1 is easily blown off or tipped over in strong wind conditions, thereby increasing the maintenance cost. In addition, when a strong wind alarm occurs around the pole tower, protective measures cannot be taken in time, and there is no windproof equipment.

[0040] like Figure 2 , Figure 4 As shown, an upper air outlet 3.1 is provided on the lower side plate of the upper installation box 3, an upper air inlet is provided on the upper side plate of the upper installation plate, and the first fan 5 is located between the upper air inlet and the upper air outlet 3.1.

[0041] In the upper installation box 3, the first fan 5 draws natural wind into the first fan 5 from the upper air inlet, and the first fan 5 then vertically supplies air downward from the upper air outlet 3.1 to form an air curtain.

[0042] like Figure 2 , Figure 3 As shown, a lower air inlet 4.1 is provided on the upper side plate of the lower installation box 4, and the second fan 6 is located below the lower air inlet 4.1, and the second fan 6 supplies air toward the tower body 1.

[0043] When the first fan 5 is started, the second fan 6 in the lower installation box 4 is started, and the wind of the wind curtain and the natural wind are drawn into the lower installation box 4 from the lower air inlet 4.1 through the second fan 6, so that a wind curtain barrier is formed on the outside of the antenna 2 to prevent the damage to the antenna 2 caused by strong external wind, thereby reducing the later manual maintenance cost.

[0044] like Figure 2 As shown, the upper air outlet 3.1 and the lower air inlet 4.1 are arranged opposite to each other in the vertical direction.

[0045] The upper air outlet 3.1 and the lower air inlet 4.1 are arranged opposite to each other in the vertical direction, so that an air curtain is formed vertically downward and the airflow direction is controllable.

[0046] like Figure 3 As shown, the lower air inlets 4.1 are distributed in a circle according to the central axis of the tower body 1, the antennas 2 correspond to the lower air inlets 4.1 one by one, and the antennas 2 are located on the inner side of the lower air inlets 4.1 relative to each other.

[0047] The antenna 2 corresponds to the lower air inlet 4.1 one by one and the antenna 2 is located on the inner side of the lower air inlet 4.1, and the upper air outlet 3.1 and the lower air inlet 4.1 are arranged opposite to each other in the vertical direction. Therefore, the antenna 2 corresponds to the upper air outlet 3.1 one by one, so that the air flow velocity of the wind curtain outside the antenna 2 is the strongest, and the wind curtain barrier corresponding to the outer side of the antenna 2 is the most stable.

[0048] like Figure 2 , Figure 5 As shown, a sleeve 7 is sleeved on the outer wall of the tower body 1 between the upper installation box 3 and the lower installation box 4 , and an annular channel 8 is formed between the sleeve 7 and the outer wall of the tower body 1 , and the annular channel 8 passes through the upper installation box 3 and the lower installation box 4 .

[0049] The annular channel 8 passes through the upper installation box 3 and the lower installation box 4, so that a circulating airflow is formed between the first fan 5 and the second fan 6, and the gas flows through the first fan 5, the air curtain, the second fan 6, the lower installation box 4, the annular channel 8, the upper installation box 3, and the first fan 5 respectively.

[0050] like Figure 2 As shown, a heating module 9 is provided in the lower installation box 4 , and the heating module 9 is located at the connection between the inner cavity of the lower installation box 4 and the annular channel 8 .

[0051] A heating module 9 is provided in the lower installation box 4. The heating module 9 is heated under the driving device. The second fan 6 supplies air toward the heating module 9. The airflow is heated by the heating module 9 and enters the annular channel 8, so that the airflow in the annular channel 8 has a certain temperature.

[0052] like Figure 5 As shown, regularly distributed air holes 10 are provided on the side wall of the sleeve 7 , and the air holes 10 penetrate the outer side of the sleeve 7 and the annular channel 8 .

[0053] The heated air flow flows through the annular channel 8, and is supplied to the space inside the upper mounting box 3 and the lower mounting box 4 from the air holes 10 on the side wall of the sleeve 7. The air flow has temperature, and a wind curtain is formed on the outside of the antenna 2, so that the temperature inside the wind curtain is higher than the temperature outside the wind curtain. The heated air flow flows through the antenna 2, so that the antenna 2 can be defrosted and de-iced when the temperature drops or in extreme weather, without affecting the communication effect of the antenna 2. The wind curtain blocks the air flow outside to form a barrier, so that heat is not easily lost over a large area, thereby reducing the energy loss of the heating module 9.

[0054] like Figure 1 , Figure 2 As shown, a lightning rod 11 is installed at the top of the tower body 1, and the lightning rod 11 is located in the middle position above the upper installation box 3. When the first fan 5 is working, a vertical downward airflow is formed at the upper air inlet on the upper side of the upper installation box 3, so that a certain wind curtain barrier is formed outside the lightning rod 11, and the damage to the lightning rod 11 by the storm is reduced in the case of strong wind.

[0055] The outer side wall of the lower installation box 4 is provided with regularly distributed natural air holes, so that the airflow pressure in the lower installation box 4 will not be too large, and the lower installation box 4 will not be damaged.

[0056] A temperature sensor and a humidity sensor are provided on the outer wall of the tower body 1, and the temperature sensor and the humidity sensor are connected and controlled by a PLC with the first fan 5 and the second fan 6. The temperature sensor and the humidity sensor are set with a value range in advance, and when the outside temperature and humidity reach a certain value range, the first fan 5, the second fan 6 and the heating module 9 are started.

[0057] The upper installation box 3 is provided with an air supply channel, which passes through the annular channel 8 and the air inlet end of the first fan 5, so that the air circulation has guiding properties.

[0058] The specific embodiments described above are only preferred implementations of the present invention, and are not intended to limit the specific implementation scope of the present invention. All equivalent changes made according to the shape and structure of the present invention should be included in the protection scope of the present invention.
